According to the invention of claim 22, the gap is formed between the urging member spanned on the surface on which the binding ring is formed, straddling between the pair of left and right binding ring holding portions. Therefore, the bound object is not guided to the guide portion and enters the gap. According to the invention of claim 23, the pair of left and right binding rings holding portions swings around the portion where the pair of left and right binding rings contact and Z or close when pivoting. The biasing member is fixed between the binding ring holding portions at a height close to the surface on the side where the binding ring protrudes, and the biasing member is a length of the binding ring holding portion. Both ends are fixed in the vicinity of the inner side of the base of the binding ring holding portion so as to bias the binding ring holding portion toward the direction of closing the binding ring. Therefore, the bound object is not guided to the guide portion and enters the gap.

The above object, other objects, features, and advantages of the present invention will be described with reference to the drawings. The power of explanation of the best mode for carrying out the invention below will become more apparent.

When the mounting portion 56 is attached to the through-holes 52a, 52b, 52c formed in the horizontal portion 52, the bottom portion 56d and the flange portion 56e are formed in a plan view. Only the collar portion 56e on the side (in the protruding direction of the binding ring) protrudes, whereas the collar portion 56d on the upper side (in the protruding direction of the binding ring) protrudes, After inserting the portion of the cylindrical body 56c above the collar portion 56e on the lower side (in the direction in which the ring protrudes) into the through holes 52a, 52b, 52c, the upper part (the protrusion of the ring ring protrudes) The upper end of the cylindrical body 56c (in the direction in which the binding ring protrudes) is crushed and stretched toward the periphery. Those which are out formed.

Then, the cylindrical main body 56c is attached to the cover sheet 12 with a flange 60 inserted into the through hole of the cylindrical main body 56c. That is, the horizontal portion 52 is fixed by the hooking force head 62a at one end of the rod 60, and the cover side is fixed by the hooking force head 62b at the other end.

[0030] The urging member 50 has a longitudinal force from the upper end (in the height direction of the cover) to the lower end (in the height direction of the cover) of the first binding member 22a. The length between the uppermost binding ring 40al and the lowermost binding ring 40a2 constituting the binding ring 40a and the uppermost binding ring 40al and the lowermost binding ring 40b2 constituting the binding ring 40b of the second binding ring member 22b The binding ring 40a is formed so that the uppermost binding ring 40b1 is positioned inside the uppermost binding ring 40al and the lowermost binding ring 40a2 is positioned inside the lowermost binding ring 40b2. In the state of being inserted between the rings 40b, the distance between the operation knob 30bl and the operation knob 30a2 is slightly shorter. Like that The biasing member 50 sandwiched between the binding ring 40a and the binding ring 40b is formed in the binding ring holding part 24a and the binding ring holding part 24b when the binding tool 20 is assembled. This is because the fixed pore 36a and the fixed pore 36b are fitted and fixed so as to be fixed.

When the urging member 50 is fixed to the binding ring holding part 24a and the binding ring holding part 24b, the binding ring 40a and the binding ring 40b are slightly shifted in the vertical direction (in the height direction of the cover), When the binding ring 40a enters between the other binding rings 40b (a state in which the binding rings 40a cross each other), the biasing member 50 is not tensioned, and the right or left side of the biasing member 50 With the gap between the fixed part 54a and the fixed part 54b slightly expanded, the fixed hole 36a of the ring holding part 24a and the fixed hole 36b of the ring holding part 24b are fitted into the fixed hole 36a and The urging member 50 is fixed to the ring holding part 24a and the ring holding part 24b at the hole edge of the fixed hole 36b.

[0031] In the state where the binding ring 40a and the binding ring 40b are closed (stable state), the alignment portion 32a of the binding ring holding portion 24a and the alignment portion 32b of the binding ring holding portion 24b are in contact with each other. The tip of ring 40a and the tip of binding ring 40b are in contact.

Since the urging member 50 has the fixing portions 54a and 54b at both ends slightly widened in the width direction, the binding ring holding portion 24a, the binding ring holding portion 24b, the binding ring 40a, and the binding ring 40b. It works to close the.

The urging member 50 includes a fixing portion 54a that is a joint portion between the binding ring holding portion 24a and the urging member 50, a hinge portion 26a and a hinge portion 26b, and a fixing portion that is a joint portion between the binding ring holding portion 24b and the urging member 50. 54b Since the force is V-shaped, the linear distance between the fixed portion 54a that is the joint and the fixed portion 54b that is the joint is slightly shortened, the entire biasing member 50 is slightly expanded, and the spring force is slightly activated.

[0032] When the binding ring 40a and the binding ring 40b are in a half-open state, that is, in a neutral state (unstable state), the alignment part 32a of the binding ring holding part 24a and the matching part 32b of the binding ring holding part 24b It is not.

Also, neither the tip of the ring 40a nor the tip of the ring 40b hits.

Since the urging member 50 is most widened, it is unstable whether the ring holding part 24a and the ring holding part 24b and the ring 40a and the ring 40b are to be closed or opened. It is a state of thought point.

The urging member 50 includes a fixing portion 54a that is a joint between the binding ring holding portion 24a and the urging member 50. Since the fixing portion 54b, which is the joining portion between the hinge portion 26a and the hinge portion 26b, the ring holding portion 24b, and the biasing member 50, is in a straight line, the fixing portion 54a that is the joining portion is fixed. The straight line distance with the part 54b is the longest. At this time, the urging member 50 is in the most unfolded state, and the spring force works most.

[0033] When the binding ring 40a and the binding ring 40b are in an open state (stable state), the matching portion 32a of the binding ring holding portion 24a and the matching portion 32b of the binding ring holding portion 24b come into contact with each other, and the binding ring 40a The tip of the ring does not touch the tip of the ring 40b.

Since the urging member 50 is slightly expanded, it acts to open the ring holding part 24a, the ring holding part 24b, the support piece 28a, and the support piece 28b.

However, since the support piece 28a hits the lower surface (in the direction in which the binding ring protrudes) of the binding ring holding portion 24b and the support piece 28b hits the lower surface (in the direction in which the binding ring protrudes), Furthermore, the ring 40a and the ring 40b cannot be opened.

The urging member 50 is a fixed portion 54a which is a joint between the ring holding portion 24a and the urging member 50, the hinge 26a and the hinge 26b, and a joint between the ring holding portion 24b and the urging member 50. Since the fixing portion 54b has a mountain shape, the straight line distance between the fixing portion 54a serving as the joining portion and the fixing portion 54b serving as the joining portion is slightly short. At this time, the urging member 50 is in a slightly expanded state, and the spring force works slightly.

[0034] When the ring 40a and the ring 40b are opened, the operation knob 30a2 and the operation knob 30b2 or the operation knob 30al and the operation knob 30bl that are separated from each other are left and right. If the ring 40a and the ring 40b are half-opened, that is, the neutral state (unstable state), the ring 40a and the ring 40b are also open (stable state). become.

When closing the open ring 40a and the ring 40b, grasp the outer surface of the ring 40a and the ring 40b with your fingers and pull them together, so that the ring 40a and the ring 40b are half open. The state, that is, the neutral (unstable) force, can also be closed, and the hole 42a and the protrusion 44a at the tip of the binding ring 40a and the hole 42b and the protrusion 44b at the tip of the binding ring 40b are fitted together. And become stable.

[0035] A gap 5 is formed between the vicinity of the connecting portion between the horizontal portion 52 and the fixing portion 54a and the vicinity of the base portion of the binding ring 40a. 8a is formed, and a gap 58b is formed between the vicinity of the connecting portion between the horizontal portion 52 and the fixing portion 54b and the vicinity of the base portion of the binding ring 40b.

[0036] The left-side opening guide surface 46a is configured to pass the object S to be bound in the right guide binding ring 40b3 or in the vicinity of the tips of the binding ring 40a and the binding ring 40b to the left guide binding ring 40a3 and the right guide ring 40a. When the binding hole S2 is moved along the loop of the binding ring 40b3 and moved to the left guide binding ring 40a3, the binding margin side edge S1 of the binding object S is moved to the upper surface (the upper surface of the left opening guide surface 46a). By sliding, it was guided to the upper surface of the horizontal portion 52 without entering the gap 58a, slid up the upper surface of the horizontal portion 52, and opened the object S to be bound in the left guide binding ring 40a3. It is configured to be in a state.

The right-side opening guide surface 48a is formed by using the left-side guide binding ring 40a3 and the right-side guide binding ring 40b3 as the binding object S near the tips of the left-side guide binding ring 40a3 and the binding ring 40b3. When the binding hole S2 is moved to the right guide binding ring 40b3 along the binding hole S2, the upper edge (the upper surface of the right opening guide surface 48a) of the binding margin side edge S1 of the object S is slid. Thus, without entering the gap 58b, it is guided to the upper surface of the horizontal portion 52, and the upper surface of the horizontal portion 52 is slid up so that the object to be bound S is opened in the right guide ring 40b3. It is configured to be able to.

[0037] The left-side closing guide surface 46b extends along the loop of the left-side guide binding ring 40a3 and the right-side guide binding ring 40b3 through the binding hole S2 of the binding object S that is open in the left-side guide binding ring 40a3. Even when the binding margin side edge S1 of the binding object S slides down on the upper surface of the horizontal part 52 and enters the gap 58a when moving to the right guide binding ring 40b3, the binding object S In accordance with the movement of the object, the binding margin side edge S1 of the object to be bound S is guided and repeated to reach the upper surface of the horizontal portion 52, and the upper surface of the horizontal portion 52 is slid. It has been.

The left closing guide surface 46b is a return guide end surface of the binding margin side edge S1 of the object S to be bound. The right closing guide surface 48b is opened in the right guide binding ring 40b3. When the binding hole S2 of the object S is moved to the left guide binding ring 40a3 along the loop of the right guide binding ring 40b3 and the left guide binding ring 40a3, the binding margin side edge S1 of the binding object S is laterally moved. Even when the upper surface of the frame 52 slides down and enters the gap 58b, the binding object S is also moved. Therefore, the binding margin side edge SI of the object to be bound S is guided and repeated to reach the upper surface of the horizontal portion 52, and the upper surface of the horizontal portion 52 is slid. The

The right closing guide surface 48b is a return guide end surface of the binding margin side edge S1 of the object S to be bound.

[0038] Thus, when trying to make the object S to be spread apart, as shown in FIG. 6, the object S is guided to the left side so that the binding margin side edge S1 does not enter the gap 58a. Slide down the upper surface of the left-side opening guide surface 46 a of the portion 46 and reach the upper surface of the biasing member 50.

In addition, when the object S to be bound is intended to close the spread state force or to rotate and move to the opposite side (for example, the front cover 12b side force is also the back cover 12c side), the binding object S is The binding margin side edge S1 enters the gap 58a from the left closing guide surface 46b to the left guiding tip 46c, slides up the upper surface of the left guiding portion 46, and the binding margin side edge S1 is bent or hooked. It can be closed or moved without doing it.

Next, a method for assembling the binding tool 20 will be described mainly based on FIGS. 11 to 13.

First, the binding ring holding part 24a and the binding ring holding part 24b are arranged in parallel, the binding ring holding part 24a and the binding ring holding part 24b are slightly shifted in the length direction, and one binding ring 40a is connected to the other binding ring 40b. And the mating part 32a and the mating part 32b are abutted to form the hinge part 26al and the hinge part 26bl, and the fixed pore 36a and the fixed fine hole 36b. The distance between the fixed part 54a and the fixed part 54b of the horizontal part 52 is approximately the same as the distance between the fixed part 54a and the fixed part 54b.

Then, the fixing portion 54a of the horizontal portion 52 is fitted to the fixed pore 36a of the binding ring holding portion 24a, and the fixing portion 54b of the horizontal portion 52 is fitted to the fixing pore 36b of the binding ring holding portion 24b. Let Next, the binding ring 40a and the binding ring 40b are opened, and the binding ring holding portion 24a and the binding ring holding portion 24b are slightly shifted in the length direction thereof, so that the top end binding ring 40al and the top end binding ring 40bl or The lower end binding ring 40a2 and the lowermost end binding ring 40b2 are moved to a position where their respective tips meet each other to be in a stable state.

At this time, the first ring member 22a and the second ring member 22b are divided into the first ring member 22a by the operation knob 30a 1 and the operation knob 3 Obi, and by the operation knob 30a2 and the operation knob 30b2. And the second binding ring member 22b is not displaced in the length direction, that is, the height direction of the cover. In addition, the attachment portion 56 is fitted into the attachment through hole 38a and the attachment through hole 38b formed in the alignment portion 32a and the alignment portion 32b of the binding ring holding portion 24a and the binding ring holding portion 24b. The first and second ring members 22a and 22b are prevented from moving in the length direction, that is, in the height direction of the cover.

The binding tool 20 is assembled through the above processes.

[0040] As described above, the first binding ring member 22a and the second binding ring member 22b of the binding tool 20 are formed by integrally molding with a synthetic resin, so that the number of molded parts is small. Assembling and immediately manufacturing costs are reduced after molding.

[0041] Further, in the binding tool 20, an elastic force is exerted so as to return to the original when the distance between both end portions of the urging member 50 is widened. Since this elastic force is used, for example, a leaf spring or a coil spring is used. No other parts are required, which also reduces assembly and immediate manufacturing costs.

Further, in this binding tool 20, as shown in FIG. 8, the operation knob 30al and the operation knob 30a2 or the operation knob 30bl and the operation knob 30b2 are rotated in one direction to approach each other, so that the binding rings 40a and 40a and The binding ring 40b can be opened, and, for example, paper having a binding hole is bound into the binding ring 40a and the binding ring 40b, or paper having a binding hole is removed from the binding ring 40a and the binding ring 40b. can do.

[0043] In the above-described example, the binding tool 20 is attached to the spine cover 12a of the cover 12 with a scissors. The force binding tool 20 may be attached to another. Further, for example, a screw, a bolt, a nut, or the like may be used as an attachment for attaching the binding tool 20 instead of the collar.

[0044] Further, in the above-described binding tool 20, the first binding ring member 22a and the second binding ring member 22b, the binding ring holding part 24a and the binding ring holding part 24b, and the biasing member 50 have a specific shape, Although formed with a specific number, they may be formed in other shapes or numbers in whole or in part.

For example, the binding ring 40a and the binding ring 40b may be formed in different shapes such as a straight line shape and a semicircular shape so as to be closed in a D-shaped ring shape. Also, for example, the ring 40a and the ring 40b may be formed in numbers other than 30 each. [0045] Next, a second embodiment will be described.

FIG. 14 is a perspective view showing an example of a ring file binding tool according to a second embodiment to which the present invention is applied. FIGS. 15, 16, 17, 18, and 19 show the ring file binding tool.

A ring file 110 shown in FIG. 14 of the second embodiment includes a synthetic resin such as polypropylene, for example, and a cover 112 having a paper strength such as cardboard. The front cover 112 includes a belt-like back cover 112a, and a front cover 112b and a back cover 112c are formed at both ends in the width direction of the back cover 112a. A binding tool 120 made of synthetic resin such as ABS is mainly attached to the inner surface of the back cover 112a of the cover 112, for example.

As shown in FIGS. 15 to 21, the binding tool 120 includes a pair of left and right first binding ring members 122a and second bindings each having a shape corresponding to the inner surface of the back cover 112a, which is a mounting region of the cover 112. The ring member 122b is slidably connected.

One of the first binding members 122 a includes a strip-shaped binding member 124 a attached to the cover 112. The binding ring holding portion 124a has a length (direction) extending in the height direction of the cover 112, and is opposed to the second binding member 122b so as to be rotatable via the one-end force hinge portion 126a in the width direction. The

Similarly, the other second binding member 122b also includes a strip-shaped binding holder 124b attached to the cover 112, and the binding holder 124b has a length (direction) extending in the height direction of the cover 112. And has a first end force in the width direction, and is abutted against the first binding ring member 122a via the hinge portion 126b.

Here, the height direction of the cover means the upward and downward directions of the arrow X shown in FIG.

[0049] The pair of left and right ring holding parts 124a and the ring holding part 124b are a pair of left and right ring holding parts 124a and a ring holding part when opening and closing the ring 140a and the ring 140b. The hinge part 126a and the hinge part 126b, which are the parts that come into contact with 124b, are pivotally fixed around the pivot part. ing. The hinge part 126a and the hinge part 126b are formed on the upper part (in the protruding direction of the ring) of the ring holding part 124a and the ring holding part 124b.

The matching portion where the binding ring holding portion 124a and the binding ring holding portion 124b are combined, that is, the matching portion 132a of the binding ring holding portion 124a and the matching portion 132b of the binding ring holding portion 124b are planar, and the binding ring It is formed so as to be substantially orthogonal to the upper surface and lower surface of the holding portion 124a and the upper surface and lower surface of the binding ring holding portion 124b, and is hinged at the upper part of the mating portion 132a and the mating portion 132b (in the direction in which the binding ring protrudes). The force of 126a and hinge 126b is formed!

The upper and lower surfaces of the binding ring holding portion 124a and the upper and lower surfaces of the binding ring holding portion 124b are in the direction in which the binding ring 14Oa and the binding ring 140b protrude, and the upper surface is the upper surface and the lower surface is the lower surface. ,

[0050] Four support pieces 128a, 128a,... Are spaced in the longitudinal direction so that the other end force protrudes outward on the other end side in the width direction of the binding ring holding portion 124a, that is, the upper surface of the mating portion 132a. Are formed with a gap. Similarly, the eight support pieces 128b, 128b,... Are extended in the longitudinal direction on the other end side in the width direction of the binding ring holding portion 124b, that is, on the upper surface of the mating portion 132b so as to protrude outward from the other end portions. Formed at intervals.

The support piece 128a and the support piece 128b are connected to the ring holding part 124a and the ring holding part 124a when the fitting part 132a and the fitting part 132b, which are the other ends in the width direction of the ring holding part 124b, are brought together. And the ring holding part 124a and the ring holding part 124b are supported so that they can swing together with the other end side in the width direction of the ring holding part 124b as a pivot. As shown in FIGS. 16 and 18, they are arranged on the inner surface side of the other end in the width direction of the binding ring holding portions 124b and 124a on the other side, that is, on the facing mating portions 132a and 132b.

[0051] The pair of left and right binding ring holding portions 124a and the binding portion 132b of the binding ring holding portion 124b are arranged in the direction in which the binding ring 140a and the binding ring 140b protrude from the binding ring holding portion 124a and the binding ring holding portion 124b. On the upper side, a pivot (region of the hinge part 126a and the hinge part 126b) is formed, and the support piece 128a protrudes from the one ring holding part 124a toward the other ring holding part 124b, and the other ring A support piece 128b protrudes from the holding part 124b toward the one ring holding part 124a, and is aligned with the mating part 132a around the pivot. When the mating portion 132b is separated, the support piece 128a of the one ring holding portion 124a comes into contact with the surface of the other ring holding portion 124b, and the support piece 128b of the other ring holding portion 124b is This is formed so as to hold the angle between the right and left ring rings 140a and 140b and to hold the ring ring 140a and the ring ring 140b open. It is made.

[0052] One binding ring holding portion 124a is formed with a recessed portion 129a for receiving the supporting piece 128b of the other binding ring holding portion 124b in succession to the support piece 128a, and the other binding ring holding portion. 124b is formed with a recessed portion 129b for accommodating the support piece 128a.

This is because, when the binding tool 120 is assembled and manufactured, the pair of left and right ring holders 124a and 124b are aligned with the pivot part (the region of the hinge part 126a and the hinge part 126b). The pair of left and right ring holders 124a and 124b are shifted in the length direction in a state in which the mating part 132a and the mating part 132b are separated from each other with the pivot part as a center, and one of the binding parts The support piece 128a of the ring holding portion 124a fits into the recessed portion 129b of the other ring holding portion 124b, and the support piece 128b of the other ring holding portion 124b is recessed in the other ring holding portion 124a. It is formed so that it can be fitted into the notch 129b and the left and right binding rings 140a and 140b can be crossed with each other. As a result, between the intersecting ring 140a and ring 140b, the biasing member is applied to the fixed hole 136a and the fixed hole 136b formed in the ring holding part 124a and the ring holding part 124b. When the fixed portion 154a and the fixed portion 154b of 150 are fixed, the distance between the left and right fixed pores 136a and 136b is determined between the left and right fixed portions 154a and 154b of the biasing member 150. The angle can be such that the length is substantially close to the interval.

[0053] A return-preventing projection 170 projects from the mating portion 132b of one binding ring holding portion 124b, and a return-preventing recessed portion 172 is formed in the other binding ring holding portion 124a. The ring holding part 124a and the ring holding part 124b are slidable in a state in which the mating part 132a and the mating part 132b are combined, so that the return preventing protrusion 170 is engaged with the return preventing recess 172. Formed. The return prevention protrusion 170 and the return prevention recess 172 constitute a movement preventing means for preventing the binding ring holding part 124a and the binding ring holding part 124b from moving in the height direction of the cover. [0054] At the time of assembling, the return-preventing recessed portion 172 shifts the pair of left and right binding rings holding portions 124a and the binding ring holding portions 124b in the length direction, so that the left and right binding rings 140a and 140b are different from each other. The biasing member is applied to the fixed pore 136a and the fixed pore 136b formed in the binding ring holding portion 124a and the binding ring holding portion 124b between the crossed binding rings 140a and 140b. When the fixed portion 154a and the fixed portion 154b of 150 are fixed, the interval between the left and right fixed pores 136a and 136b is set between the left and right fixed portions 154a and 154b of the biasing member 150. An assembly recess 174 for accommodating the return prevention protrusion 170 is continuously formed so as to have an angle that is substantially close to the interval.

The recessed portion 172 for preventing return and the recessed portion 174 for assembly have substantially the same shape, and the recessed portion 172 for preventing return includes an inclined surface 172a corresponding to the inclined surface 170a of the return preventing protrusion 170 and the return surface. The assembling recess 174 includes an inclined surface 174a corresponding to the inclined surface 170a of the return preventing projection 170 and the return preventing projection 170. Engagement surface 170b and a corresponding engagement surface 174b.

The return prevention protrusion 170 shifts the pair of ring holding parts 124a and the ring holding parts 124b in the length direction, and holds the other ring holding when the left and right ring rings 140a and 140b are brought together. Inclination 170a slidably contacting the mating portion 132a of the portion 124a, and the return prevention recess formed in the mating portion 132a of the other ring holding portion 124a when the left and right binding rings 140a and 140b are brought together And an engaging surface 170b engaged with the portion 172. This inclined surface 170a is formed on a slope that becomes lower in the direction of displacement!

[0055] The first binding ring member 122a has an operation knob 130a1 and an operation knob 130a2 at both ends in the longitudinal direction, and the second binding ring member 122b has an operation knob 130bl and an operation knob at both ends in the longitudinal direction. Only 130b2.

The operation knob 130al has a second binding ring member 122b from the first binding ring member 122a so that the operation knob 130a 1 of the first binding ring member 122a and the operation knob 130b 1 of the second binding ring member 122b intersect each other. And the operation knob 130bl is obliquely upward from the second binding member 122b toward the first binding member 122a (in the direction in which the binding ring protrudes). In).

The left-side closing guide surface 146b, which also has a curved surface force, is formed, and the left-side opening guide surface 146a and the left-side closing guide surface 146b intersect with each other above the upper surface of the biasing member 150. The biasing member 150 protrudes to a position that closes the left gap 158a formed between the left end edge of the biasing member 150 and the inner surface of the left guide binding ring 140a3.

[0062] The right guide portion 148 is formed with a right-side opening guide surface 148a having an oblique force following the inner surface where the distal end force of the right guide binding ring 140b3 continues, and the inner surface from the binding ring holding portion 124b. A right-side closing guide surface 148b made of a curved surface is formed, and the right-side opening guide surface 148a and the right-side closing guide surface 148b intersect with each other at the right-side guide tip 148c above the upper surface of the biasing member 150. Then, the biasing member 150 is projected and formed to a position that closes the right gap 158b formed between the right end edge of the urging member 150 and the inner surface of the right guide binding ring 140b3.

[0063] The left guide ring 140a3 is between the uppermost end ring 140al and the lowermost end ring 140a2, and the right guide ring 140b3 is the uppermost end ring 140bl and the lowermost end ring 140b2. In between, four are formed at appropriate intervals on the left and right sides.

[0064] The binding ring 140a and the binding ring 140b are formed by combining the binding ring holding portion 124a and the binding ring holding rod 124b with the hinge 咅 126a and the hinge 咅 126b. Are closed when approaching the cover 112 and conversely, they are opened when they are moved away from the cover 112.

Further, holes 142a and protrusions 144a are alternately formed at the tips of the respective ring rings 140a, and the protrusions that fit into the holes 142a when the ring rings 140a and the ring rings 140b are closed are formed at the tips of the ring rings 140b. 1 44b and holes 142b that fit into the projections 144a are alternately formed.

Some of these protrusions 144a and 144b are formed larger than the others, and the holes 142a and 142b at positions corresponding to the protrusions 144a and 144b formed larger are the other holes 142a. And deeper than the hole 142b.

[0065] In the first ring member 122a, the ring ring holding part 124a and the operation knob 130a 1 and the operation knob 130a2 and the ring ring 140a are integrally formed of synthetic resin, and the second ring member 122b is formed of the ring ring holding part. 124 b, operation knobs 130bl and 130b2, and ring 140b are integrally formed of synthetic resin.

[0066] The urging member 150 includes a semicircular arc-shaped horizontal section 152 that swells upward (in the direction in which the binding ring protrudes), and a downward direction (the protrusion of the binding ring protrudes) from both ends of the horizontal section 152. A pair of left and right fixing parts 154a and 154b projecting inwardly (in the direction), and the fixing part 154a fits into the fixed pore 136a extending in the length direction of the ring holding part 124a. The fixing portion 154b is fitted into a fixing pore 136b extending in the length direction of the ring holding portion 124b, and the upper surfaces of the ring holding portion 124a and the ring holding portion 124b (in the protruding direction of the ring). And fixed so as to sandwich the fixed pore 136a and the fixed pore 136b. [0067] The pair of left and right ring holders 124a and 124b is configured to shift the pair of ring holders 124a and 124b in the length direction so that the left and right ring rings 140a and 140b A biasing member is formed between the fixed ring 136a and the fixed hole 136b formed in the ring holding part 124a and the ring holding part 124b between the ring 140a and the ring 140b crossed alternately. 150 fixing parts 154a and 154b are fixed, and the pair of binding rings holding part 124a and binding ring holding part 124b are shifted in the length direction so that the right and left binding rings 140a and 140b are joined together. However, the fixed hole 136b of the other ring holding part 124b is displaced from the position of the one ring holding part 132a when the fixing part 154b of the urging member 150 is fitted. Therefore, the direction in which the binding ring holding portion 124b is displaced (the downward direction of the arrow in FIG. 31 and the downward direction of the cover height) ) It is extended on the opposite side of the.

[0068] The pair of left and right ring holders 124a and 124b shift the pair of ring holders 124a and ring holders 124b in the length direction thereof, and Crossing alternately, between the intersecting ring 140a and ring 140b, straddle between the fixed hole 136a and the fixed hole 136b formed in the ring holding part 124a and the ring holding part 124b. After the fixing portion 154a and the fixing portion 154b of the urging member 150 are fixed in the state of being covered with the crown, the pair of the ring holding portions 124a and the ring holding portions 124b are shifted in the length direction thereof, and the left and right bindings The ring 140a and the ring 140b can be mated together, and the fixed portion 154a of the biasing member 150 is fitted into the fixed pore 136a and the fixed portion 154b of the biasing member 150 is fitted into the fixed pore 136b. Thus, the ring holding portion 124b is displaced and the angle at which the ring holding portion 124a and the ring holding portion 124b are brought together changes. It is, at positions summed Ki wants right of the binding rings 140a and Tsuzuriwa 140b, and movement prevention means 176 is formed in order to prevent the biasing member 150 moves, Ru.

[0069] The urging member movement preventing means 176 fixes the end 132b1 of the fixed pore 136b of one of the pair of left and right ring holders 124b and the other end of the ring holder 124a. Of the terminal end 132al and the terminal end 132a2 of the narrow hole 136a, the fixing part 124b of the one ring holding part 124b is formed by the terminal part 136al on the opposite side in the length direction of the ring holding part. Note that the length of the fixed pore 136a of the ring holding portion 124a (that is, the length between one end 136al of the fixed pore 136a and the other end 136a2 of the fixed pore 136a). The length between them is substantially the same as the length of the fixing portion 154a of the urging member 150.

[0070] The urging member 150 is a metal plate panel in which an attachment portion 156 for attachment to the cover 112 is formed from the horizontal portion 152 toward the binding ring holding portions 124a and 124b.

The attachment portion 156 is inserted into the attachment through holes 138a and 138b formed in the matching portions 132a and 132b of the pair of left and right binding ring holding portions 124a and 124b at the center in the width direction, and the horizontal portion 152 It is formed so as to be fixed to the cover 112 in the vicinity of the tip on the opposite side.

[0071] The attachment portion 156 has a length for allowing the binding ring holding portions 124a and 124b to be attached to the cover 112 at a height that allows the pair of left and right binding ring holding portions 124a and 124b to swing. I have. In this embodiment, the mounting portion 156 is provided in the vicinity of the upper end and the lower end and in the center in the height direction of the cover of the horizontal portion 152 of the urging member 150. A hollow cylindrical body 156c having openings 156a, 156b on the 152 side and the cover 112 side, and a circular flange 156d in plan view protruding from the upper end of the hollow cylindrical body 156c over the entire circumference and a collar 156e, and when attaching the attachment part 156 to the through holes 152a, 152b, 152c drilled in the horizontal part 152, only the collar part 156e on the lower side (in the direction in which the binding ring protrudes) initially On the other hand, the collar portion 156d on the upper side (in the direction in which the binding ring protrudes) is extended to the lower side (in the direction in which the binding ring protrudes). Penetrates the prosthesis of the cylindrical body 156c above the collar 156e (in the direction of the protruding ring) 152a, 152b, 152c [After insertion, the upper end of the cylindrical body 156c (in the direction in which the binding ring protrudes) is crushed from the top (in the direction in which the binding ring protrudes) It is formed to project toward the periphery.

Then, the cylindrical main body 156c is attached to the cover 112 by a hook 160 inserted into the through hole of the cylindrical main body 156c. That is, the horizontal portion 152 is fixed by the hooking force head 162a at one end of the rod 160, and the cover side is fixed by the hooking force head 162b at the other end.

[0072] The pair of left and right binding ring holding portions 124a and the binding ring holding portion 124b have a length extending in the height direction of the cover, and are attached through holes 138a for attachment and attachments for attaching the attachment portions 156. A through hole 138b for use is formed.

The mounting through-hole 138a and the mounting through-hole 138b are formed at a normal mounting position of the mounting portion 156, and the mounting through-hole 138b of the other binding ring holding portion 124b has a normal mounting position force. Thus, an assembly through-hole 138bl for accommodating at least the mounting portion 156 is formed. This is because when the binding tool 120 is assembled and manufactured, the mounting portion 186 fits into the mounting through hole 138a and the assembly through hole 138bl, and the pair of left and right binding ring holding portions 124a and In a state in which the ring holding portion 124b is aligned and the alignment portion 132a and the alignment portion 132b are separated from each other about the pivot portion, the pair of left and right binding ring holding portions 124a and the ring holding portion 124b are arranged in the length direction. The left and right ring rings 140a and 140b are formed so as to be able to cross each other.

The biasing member 150 has a length in the length direction from the upper end (in the height direction of the cover) to the lower end (in the height direction of the cover), and the binding ring 140a of the first binding member 122a is The length between the uppermost binding ring 140al and the lowermost binding ring 140a2 and the binding ring of the second binding member 122b 1 The length between the uppermost binding ring 140al and the lowermost binding ring 140b2 constituting the 40b The upper ring 140a is positioned between the ring 140b so that the uppermost ring 140bl is positioned inside the uppermost ring 140al and the lowermost ring 140a2 is positioned inside the lowermost ring 140b2. In the intruded state, it is formed slightly shorter than the interval between the operation knob 130b1 and the operation knob 130a2. The reason for this configuration is that when the binding tool 120 is assembled, the biasing member 150 sandwiched between the binding ring 140a and the binding ring 140b is attached to the binding ring holding part 124a and the binding ring holding part 124b. This is because the fixed pore 136a and the fixed pore 136b that are formed are fitted between the fixed pore 136a and can be fixed.

When the urging member 150 is fixed to the binding ring holding part 124a and the binding ring holding part 124b, the binding ring 140a and the binding ring 140b are slightly shifted in the vertical direction (in the height direction of the cover), In a state in which the binding ring 140a enters between the other binding rings 140b (a state in which the binding rings 140b are alternately crossed), the biasing member 150 is not applied with a tension force, or the right and left fixing portions 154a and 154b of the biasing member 150 With the gap slightly expanded, the fixed hole 136a of the ring holding part 124a and the fixed hole 136b of the ring holding part 124b are fitted into the fixed hole 1 The biasing member 150 is fixed to the binding ring holding portion 124a and the binding ring holding portion 124b with the hole edges of the 36a and the fixing hole 136b.

[0074] In a state where the binding ring 140a and the binding ring 140b are closed (stable state), the alignment portion 132a of the binding ring holding portion 124a and the alignment portion 132b of the binding ring holding portion 124b are separated from each other, The tip of the ring 140a and the tip of the ring 140b are in contact.

The urging member 150 has a fixed portion 154a and a fixed portion 154b at both ends in the width direction that are slightly expanded! / Ring, so that the binding ring holding portion 124a and the binding ring holding portion 124b and the binding ring 140a and the binding member 150 Acts to close ring 140b.

The urging member 150 is a fixed portion 154a, a hinge portion 126a and a hinge portion 126b, which is a joint portion between the binding ring holding portion 124a and the urging member 150, and a fixing portion, which is a joint portion between the binding ring holding portion 124b and the urging member 150. Since 154b is V-shaped, the linear distance between the fixed part 154a that is the joint and the fixed part 15 4b that is the joint is slightly shortened, the entire biasing member 150 is slightly widened, and the spring force works slightly. .

[0075] When the binding ring 140a and the binding ring 140b are in a half-open state, that is, in a neutral state (unstable state), the matching portion 132a of the binding ring holding portion 124a and the matching portion of the binding ring holding portion 124b It does not hit 132b.

Further, neither the front end of the binding ring 140a nor the front end of the binding ring 140b hits.

Since the urging member 150 is most widened, it is unstable whether the ring holding part 124a and the ring holding part 124b and the ring 140a and the ring 140b are to be closed or opened. This is the state of thought.

The biasing member 150 includes a fixing portion 154a, a hinge portion 126a and a hinge portion 126b, which are joint portions between the binding ring holding portion 124a and the biasing member 150, and a connecting portion between the binding ring holding portion 124b and the biasing member 150. Since the fixing portions 154b are aligned in a straight line, the linear distance between the fixing portion 154a as the joint portion and the fixing portion 154b as the joint portion is the longest. At this time, the urging member 150 is in the most unfolded state, and the spring force works most.

[0076] When the binding ring 140a and the binding ring 140b are in an open state (stable state), the binding portion 132a of the binding ring holding portion 124a and the matching portion 132b of the binding ring holding portion 124b are in force contact with each other, and the binding ring The tip of 140a does not touch the tip of ring 140b. Since the urging member 150 is slightly expanded, the biasing member 150 acts to open the hinge portion 126a of the binding ring holding portion 124a and the hinge portion 126b of the binding ring holding portion 124b.

However, since the matching part 132a of the binding ring holding part 124b and the matching part 132b of the binding ring holding part 124a are in contact with each other, the binding ring 140a and the binding ring 140b cannot be opened any further.

The biasing member 150 includes a fixing portion 154a, a hinge portion 126a and a hinge portion 126b, which are joint portions between the binding ring holding portion 124a and the biasing member 150, and a connecting portion between the binding ring holding portion 124b and the biasing member 150. Since the barrel fixing portion 154b has a mountain shape, the linear distance between the junction fixing portion 154a and the junction fixing portion 154b is slightly shorter. At this time, the urging member 150 is in a slightly widened state, and the spring force works slightly.

[0077] When the ring 140a and the ring 140b are opened, the operation knob 130a2 and the operation knob 130b2 or the operation knob 130a 1 and the operation knob 130b 1 that are separated from each other are picked up with fingers. If the distance is reduced, the ring 140a and the ring 140b are in a half-open state, that is, the neutral (unstable) force is also applied to the ring 140a and the ring 140b (stable) State).

When closing the open ring 140a and the ring 140b, if the outer surfaces of the ring 140a and the ring 140b are gripped with fingers and pulled together, the ring 140a and the ring 140b are half-opened. From the neutral state (unstable state) to the closed state, and the holes 142a and projections 144a at the end of the ring 140a and the holes 142b and 144b at the end of the ring 140b are fitted. Together, it becomes a stable state.

[0078] A gap 158a is formed between the vicinity of the connecting portion between the horizontal portion 152 and the fixing portion 154a and the vicinity of the base portion of the binding ring 140a, and in the vicinity of the connecting portion between the horizontal portion 152 and the fixing portion 154b. A gap 158b is formed between the ring and the vicinity of the base of the ring 140b.

[0079] The left-side opening guide surface 146a is provided on the right guide binding ring 140b3 or in the vicinity of the binding ring 140a and the front end of the binding ring 140b. When the binding hole S2 is moved along the loop of the binding ring 140b3 and moved to the left guide binding ring 140a3, the binding margin side edge S1 of the object S to be bound is moved to the upper surface (the upper surface of the left opening guide surface 146a). By sliding, it is guided to the upper surface of the horizontal portion 152 without entering the gap 158a, and the upper surface of the horizontal portion 152 is slid and raised, and the object S to be bound is opened in the left guide binding ring 140a3. It is configured to be in a state.

The guide surface 148a for opening on the right side is the left side guide binding ring 140a3 and the right side guide binding ring 140b3, which is located on the left guide binding ring 140a3 or near the tip of the binding ring 140a and the binding ring 140b. When the binding hole S2 is moved to the right guide binding ring 140b3 along the binding hole S2, the upper edge (the upper surface of the right opening guide surface 148a) of the binding margin side edge S1 of the object S is slid. As a result, it is guided to the upper surface of the horizontal portion 152 without entering the gap 158b, and the upper surface of the horizontal portion 152 is slid and raised, so that the object to be bound S is opened in the right guide binding ring 140b3. It is configured to be able to

[0080] The left-side closing guide surface 146b extends along the loop of the left-side guide binding ring 140a3 and the right-side guide binding ring 140b3 through the binding hole S2 of the binding object S that is open in the left-side guide binding ring 140a3. Even if the binding margin side edge S1 of the binding object S slides down on the upper surface of the horizontal portion 152 and enters the gap 158a when moving to the right guide binding ring 140b3, the binding object S Is configured so that the binding edge S1 of the binding object S is guided and repeated to reach the upper surface of the horizontal portion 152 and slide on the upper surface of the horizontal portion 152. It has been done.

The left closing guide surface 146b is a return guide end surface of the binding margin side edge S1 of the object S to be bound.

The right closing guide surface 148b is formed on the right guide binding ring 140b3 with the binding hole S2 of the object S to be opened on the left side along the loop of the right guide binding ring 140b3 and the left guide binding ring 140a3. Even when the binding margin side edge S1 of the binding object S slides down on the upper surface of the horizontal portion 152 and enters the gap 158b when moving to the guide binding ring 140a3, it follows the movement of the binding object S. The binding margin side edge S1 of the object to be bound S is guided and repeated to reach the upper surface of the horizontal portion 152, and the upper surface of the horizontal portion 152 is slid. .

The right closing guide surface 148b is a return guide end surface of the binding margin side edge S1 of the object S to be bound.

[0081] Thus, when trying to make the object S to be spread apart, as shown in FIG. 20, the object to be bound S has a left guide portion where the binding margin side edge S1 does not enter the gap 158a. Left side of 146 Slide down the upper surface of the opening guide surface 146a and reach the upper surface of the biasing member 150.

In addition, when the object S to be bound is intended to close the spread state force or to rotate and move to the opposite side (for example, from the front cover 1 12b side to the back cover 112c side), the object S to be bound is The binding margin side edge S1 reaches the left guide end 146c from the left closing guide surface 146b without entering the gap 158a, slides up the upper surface of the left guide portion 146, and the binding margin side edge S1 is bent. It can be closed and moved without hanging or hanging.

Next, a method for assembling the binding tool 120 will be described mainly with reference to FIGS.

First, the binding ring holding part 124a and the binding ring holding part 124b are arranged in parallel, the binding ring holding part 124a and the binding ring holding part 124b are slightly shifted in the length direction, and one binding ring 140a is connected to the other binding ring 140b. Between the mating part 132a and the mating part 132b to form the hinge part 126al and the hinge part 126b 1 to form the fixed hole 136a and the fixed hole 136b. Is set to a length substantially close to the distance between the fixed portion 154a and the fixed portion 154b of the urging member 150.

At this time, the support piece 128a of one of the ring holding portions 124a is fitted into the recess 129b of the other ring holding portion 124b, and the support piece 128b of the other ring holding portion 124b is the other ring. It fits into the recessed part 129b of the holding part 124a, and the left and right binding rings 140a and 140b intersect each other.

The length reaching the knob 30b2 (that is, the distance between the two) is configured to be substantially the same, and the first binding ring in the length direction of the binding ring holding portion 24a and the binding ring holding portion 24b (that is, the height direction of the cover). The operation knob 30b 1 of the second binding ring member 22b is positioned below the operation knob 30al of the member 22a (in the height direction of the cover), and the lower side of the operation knob 30a2 of the first binding ring member 22a (the height of the cover) In the vertical direction, the operation knob 30b 1 of the second binding ring member 22b is positioned!

Therefore, the first binding member 22a and the second binding member 22b are prevented from moving in the length direction of the first binding member 22a and the second binding member 22b, that is, in the height direction of the cover. ing. Here, the height direction of the cover means the upward and downward directions of the arrow X shown in FIG.

[0095] As shown in FIGS. 41, 43 and 50, for example, 26 arcuate ring rings 40a, 40a,... It is formed with an interval of. Similarly, for example, 30 arcuate ring rings 40b, 40b,... Are formed at regular intervals in the longitudinal direction on the upper surface that is the outside of the ring holding part 24b.

The binding rings 40a and 40b are closed when the matching portions 32a and 32b are brought close to the cover 12 in the hinge portions 26a and 26b of the combined ring holding portions 24a and 24b, and conversely, the cover 12 It is formed so that it opens when it is away from it.

In addition, holes 42a and protrusions 44a are alternately formed at the tips of the respective ring portions 40a, and protrusions 44b that fit into the holes 42a when the ring portions 40a and 40b are closed are formed at the tips of the respective ring portions 40b. The holes 42b that fit into the protrusions 44a are alternately formed.

Some of these protrusions 44a and 44b are formed larger than the others, and the holes 42a and 42b at positions corresponding to the protrusions 44a and 44b formed larger than the other holes 42a and 42b. Deeply formed.

[0096] On the upper surface (in the protruding direction of the binding ring) of the binding ring holding part 24a, a fixed pore 36a extending in the longitudinal direction of the binding ring holding part 24a is formed in the vicinity of the inner side of the base part of the binding ring 40a. On the upper surface of the part 24b (in the direction in which the binding ring protrudes), keep the binding ring near the inside of the base of the binding ring 40b. Fixed pores 36b extending in the longitudinal direction of the holding portion 24b are formed.

[0097] In the first ring member 22a, the ring holding part 24a and the operation knob 30al and the operation knob 30a2 and the ring 40a are integrally formed of synthetic resin, and the second ring member 22b is formed of the ring holding part 24b. The operation knobs 30bl and 30b2 and the ring 40b are integrally formed of synthetic resin.

[0098] The urging member 50 includes a semicircular arc plate-like horizontal section 52 that bulges upward (in the direction in which the binding ring protrudes), and a downward direction (direction in which the binding ring protrudes) from both ends of the horizontal section 52. And a pair of left and right fixing portions 54a and 54b projecting inwardly, and the fixing portion 54a is fitted into a fixing pore 36a extending in the length direction of the ring holding portion 24a, The fixing portion 54b is fitted into a fixed pore 36b extending in the length direction of the binding ring holding portion 24b, and is fixed so as to sandwich the fixed pore 36a and the fixed pore 36b.

The urging member 50 is a metal plate panel in which an attachment portion 56 for attaching to the cover 12 is formed from the horizontal portion 52 toward the binding ring holding portions 24a and 24b.

[0100] The attachment portion 56 is a length that allows the binding ring holding portions 24a, 24b to be attached to the cover 12 at a height that allows the pair of left and right binding ring holding portions 24a, 24b to swing. Is equipped.

The mounting portion 56 has a hollow cylindrical main body 56c having openings 56a and 56b on the horizontal portion 52 side and the cover 12 side, and the entire upper end of the hollow cylindrical main body 56c (in the direction in which the binding ring protrudes). When the mounting portion 56 is attached to the through-holes 52a, 52b, 52c formed in the horizontal portion 52, the bottom portion 56d and the flange portion 56e are formed in a plan view. Only the collar part 56e on the side (ぉ in the direction in which the binding ring protrudes) protrudes and The flange 56d on the side (in the direction in which the binding ring protrudes) protrudes, and the cylindrical body on the lower side (in the direction in which the binding ring protrudes) is located above the flange 56e. After the 56c portion is inserted into the through holes 52a, 52b, 52c, the upper end (in the protruding direction of the staple ring) of the cylindrical main body 56c is crushed from above (in the protruding direction of the staple ring), and toward the periphery. It is an overhang formed.

[0101] The urging member 50 has a longitudinal force from the upper end (in the height direction of the cover) to the lower end (in the height direction of the cover) of the first binding member 22a. The length between the uppermost binding ring 40al and the lowermost binding ring 40a2 constituting the binding ring 40a and the uppermost binding ring 40al and the lowermost binding ring 40b2 constituting the binding ring 40b of the second binding ring member 22b The binding ring 40a is formed so that the uppermost binding ring 40b1 is positioned inside the uppermost binding ring 40al and the lowermost binding ring 40a2 is positioned inside the lowermost binding ring 40b2. In the state of being inserted between the rings 40b, the distance between the operation knob 30bl and the operation knob 30a2 is slightly shorter. The reason for this is that when the binding tool 20 is assembled, the urging member 50 sandwiched between the binding ring 40a and the binding ring 40b is attached to the binding ring holding part 24a and the binding ring holding part 24b. This is so that the fixed pore 36a and the fixed pore 36b formed can be fitted and fixed across the fixed pore 36b.

When the urging member 50 is fixed to the binding ring holding part 24a and the binding ring holding part 24b, the binding ring 40a and the binding ring 40b are slightly shifted in the vertical direction (in the height direction of the cover), When the binding ring 40a enters between the other binding rings 40b (a state in which the binding rings 40a cross each other), the biasing member 50 is not tensioned, and the right or left side of the biasing member 50 The biasing member 50 is fitted to the fixed hole 36a of the ring holding part 24a and the fixed hole 36b of the ring holding part 24b with the fixing part 54a and the fixed part 54b slightly expanded. Secure to the ring holder 24a and the ring holder 24b.

[0102] In the state where the binding ring 40a and the binding ring 40b are closed (stable state), the alignment portion 32a of the binding ring holding portion 24a and the alignment portion 32b of the binding ring holding portion 24b are in contact with each other. Tip and ring of ring 40a It hits the tip of 40b.

[0103] When the binding ring 40a and the binding ring 40b are in a half-open state, that is, in a neutral state (unstable state), the alignment part 32a of the binding ring holding part 24a and the matching part 32b of the binding ring holding part 24b It is not.

Also, neither the tip of the ring 40a nor the tip of the ring 40b hits.

The urging member 50 is a fixed portion 54a which is a joint between the ring holding portion 24a and the urging member 50, the hinge 26a and the hinge 26b, and a joint between the ring holding portion 24b and the urging member 50. Since the fixing portions 54b are arranged in a straight line, the linear distance between the fixing portion 54a that is the joining portion and the fixing portion 54b that is the joining portion is the longest. At this time, the urging member 50 is in the most unfolded state, and the spring force works most.

[0104] When the binding ring 40a and the binding ring 40b are in an open state (stable state), the matching portion 32a of the binding ring holding portion 24a and the matching portion 32b of the binding ring holding portion 24b come into contact with each other, and the binding ring 40a The tip of the ring does not touch the tip of the ring 40b.

However, since the support piece 28a hits the lower surface (in the direction in which the binding ring protrudes) of the binding ring holding portion 24b and the support piece 28b hits the lower surface (in the direction in which the binding ring protrudes), Furthermore, the ring 40a and the ring 40b cannot be opened. The urging member 50 is a fixed portion 54a which is a joint between the ring holding portion 24a and the urging member 50, the hinge 26a and the hinge 26b, and a joint between the ring holding portion 24b and the urging member 50. Since the fixing portion 54b has a mountain shape, the straight line distance between the fixing portion 54a serving as the joining portion and the fixing portion 54b serving as the joining portion is slightly short. At this time, the urging member 50 is in a slightly expanded state, and the spring force works slightly.

[0105] When the ring 40a and the ring 40b are opened, the operation knob 30a2 and the operation knob 30b2 or the operation knob 30al and the operation knob 30bl that are separated from each other are left and right. If the ring 40a and the ring 40b are half-opened, that is, the neutral state (unstable state), the ring 40a and the ring 40b are also open (stable state). become.

Next, an assembling method of the binding tool 20 of the third embodiment will be described mainly based on FIG. 50 or FIG.

Then, the fixing portion 54a of the horizontal portion 52 is fitted to the fixed pore 36a of the binding ring holding portion 24a, and the fixing portion 54b of the horizontal portion 52 is fitted to the fixing pore 36b of the binding ring holding portion 24b. Let Next, the binding ring 40a and the binding ring 40b are opened, and the binding ring holding portion 24a and the binding ring holding portion 24b are slightly shifted in the length direction thereof, so that the top end binding ring 40al and the top end binding ring 40bl or Move the lower end binding ring 40a2 and the lowermost end binding ring 40b2 to the position where their tips meet, A stable state is assumed.

At this time, the first and second binding members 22a and 22b are formed by the operation knob 30al and the operation knob 30bl, and by the operation knob 30a2 and the operation knob 30b2. There is no deviation in the length direction of the ring member 22b, that is, the height direction of the cover. In addition, the attachment portion 56 is fitted into the attachment through hole 38a and the attachment through hole 38b formed in the alignment portion 32a and the alignment portion 32b of the binding ring holding portion 24a and the binding ring holding portion 24b. The first and second ring members 22a and 22b are prevented from moving in the length direction, that is, in the height direction of the cover.

The binding tool 20 is assembled through the above processes.
