These prismatic elements (31, 32) couple along a coupling direction (100) allowing relative motion between said plates (10, 20) accompanied by a variation in the width of the frame (8). The buckle (1) according to the utility model also comprises stop means provided to prevent separation of the second plate (10) from the first plate (10).

Description

BUCKLE FOR BELT

DESCRIPTION

The present invention relates to a buckle to be attached to a belt usable as clothing accessory. The invention also relates to a belt comprising such as buckle.

As it is known, buckles constitute the end part of a belt and are provided to allow fastening thereof. Conventionally, belt buckles are formed of a frame, generally made of metal or plastic, which is attached to an end of the belt. When used, the latter is made to pass inside the frame and secured (buckled) through a stop means operatively associated with said frame.

In a first type of known and widely used buckles, this stop means is constituted by a pin, also called tongue, which is inserted into one of the holes previously made in the belt. In the case of the belts made of particularly precious leathers, such as crocodile, the perforation operation represents a delicate, and therefore costly, technological step, since it could potentially damage the aesthetic integrity of the belt.

A second type of widely used buckles partly overcomes this drawback by producing a fastening of the belt that does not require holes to be produced therein. With a view to this, the American patents US1278340, US1352937, US1384061 and US1850944 show buckle structures belonging to this second type. In substance these buckles are realized by a support to which an end of the belt is secured. The support is substantially constituted by a plate which remains visible during normal use of the belt. From one of the surfaces of the plate, the one not visible, two lateral edges extend, produced on each of which is a guide groove for one end of a transverse pin which constitutes an element movable with respect to the plate. The belt is placed during use between the surface of the plate that is not visible and the transverse pin which by moving exerts a pressure on the belt so as to secure it, preventing movement thereof. If, on the one hand, this solution makes it possible to limit operations on the belt, on the other this type of buckle has proved to have some drawbacks with regard to practical use. In fact, with regard to the fastening principle, in many cases the transverse pin tends to move with difficulty along the grooves making fastening difficult and not very efficient. Moreover, the configuration of many of these buckles is rather complex and also somewhat unreliable. This complexity is found above all in those parts of the buckle provided to allow attachment thereof to the end of the belt.

On the basis of these considerations, the main aim of the present invention is to provide a buckle for a belt that allows the aforesaid drawbacks to be overcome.

Within the scope of this aim an object of the invention is to provide a buckle whose fastening principle does not require operations on the belt potentially damaging for the integrity thereof.

Another object of the present invention is to provide a buckle with a simple configuration which is also easy to attach to an end of a belt.

A further object of the present invention is to provide a buckle that is produced from a limited number of elements easy to produce and easy to assemble together.

Not the last object of the present invention is to provide a buckle that is reliable, easy to produce and with competitive costs.

This aim and these and other objects which will be more apparent from the description, are achieved through a buckle for belt according to the indications in claim 1 and in the dependent claims.

Once the buckle according to the invention has been attached to an end of a belt, it allows this belt to be fastened easily without requiring particular preliminary operations, above all the production of fastening holes. This feature makes the buckle particularly suitable to be attached to belts made of particularly valuable material. Moreover the particularly compact configuration of the buckle and the limited number of components thereof ensure simple and efficient fastening of the belt to which the buckle is attached.

Further characteristics and advantages will be more apparent from the description of preferred, but not exclusive, embodiments of the buckle according to the invention, shown by way of a non-limiting example in the accompanying drawings, in which: figure 1 is a perspective view of a first embodiment of a buckle according to the present invention;

- figure 15 is a view of an end of a belt to which a buckle according to the present invention is attached.

With reference to the aforesaid figures, the buckle 1 according to the present invention comprises a first plate 10 provided with a first flat portion 11 and a first pair of opposed sides 17, 18 which extend from the first flat portion 11. The first flat portion 11 defines a coupling surface 12 for connecting the buckle 1 to a first end of a belt 2. As described below, the buckle 1 comprises connection means provided to connect an end 2A of the belt 2 to said coupling surface 12.

It must be understood that for the objects of the present invention the expression belt is intended in general as a strip of flexible material which has an end 2A suitable to be connected to a buckle so as to form a clothing accessory.

The buckle 1 also comprises a second plate 20 provided with a second flat portion 21 and with a second pair of sides 27, 28 which extend from the second flat portion 21 so as to give the second plate 20 a substantially C-shaped configuration similar to the first plate 10.

The first plate 10 and the second plate 20 are mutually coupled through coupling means that slidingly couple at least a first side 17 of the first plate 10 to a corresponding first side 27 of the second plate 20. More specifically, through said coupling means the two plates 10 and 20 are coupled so that the respective flat portions 11 and 21 are mutually facing thus defining a frame 8 for a portion of the belt 2, substantially opposite the portion connected to the buckle 1, to pass through.

According to the present invention, the coupling means comprise a first pair of mating prismatic elements 31 and 32 which by coupling define a prismatic kinematic pair. More specifically, the pair of prismatic elements 31 and 32 is constituted by a first prismatic element 31 associated with said first side 17 of the first plate 10 and a second prismatic element 32 associated with said corresponding first side 27 of the second plate 20. The expression "associated" is intended both as the possibility of producing the prismatic elements integral with the relative sides, but also as the possibility of "attaching" these prismatic elements to said sides.

The prismatic elements 31 and 32 extend and are coupled according to a coupling direction 200 inclined with respect to the flat portions 11 and 21 of the two plates 10 and 20 of the buckle 1 to allow a relative motion therebetween accompanied by a variation in the width of the frame 8. In other words, by coupling along this inclined coupling direction 200, the prismatic elements 31 and 32 allow a relative motion of the second plate 20 with respect to the first 10 so that the second flat portion 21 moves away from or toward the first flat portion 11 increasing or decreasing the distance between these flat portions 11 and 21.

The relative motion between the two plates 10 and 20 forms the essence of the fastening principle of the buckle 1. In fact, once a predetermined portion of belt 2 has been made to pass inside the frame 8, an action on one of the two plates (preferably on the second plate 20), performed by the user, translates into a compression of the portion of belt 2 interposed between the two flat portions 11 and 21. In this way fastening of the belt 2 is obtained through pressure between the flat surfaces. A more detailed discussion of this fastening principle will be provided below during the description.

The buckle 1 according to the present invention also comprises stop means provided to prevent separation of the second plate 20 from the first plate 10. These stop means comprise at least one pin element 41 which is interposed between the prismatic elements mutually coupled along the coupling direction 200. In the solutions shown this pin element 41 projects transversely with respect to the coupling direction from the second prismatic element 32 (for example defined by a groove) to be positioned during operation in a longitudinal seat 42 produced on the other prismatic element 31 (for example a raised track geometrically mating with said groove). In practice, the pin element 41 stops the relative motion of the second plate 20 with respect to the first plate 10 in a predetermined position, in substance preventing the two plates 10, 20 from separating by sliding. It must be understood that the expression "pin element" indicates any element, whether pin, screw or other functionally equivalent element, so that once positioned in the seat 42 it performs the stop function described above.

Figure 1 is a perspective view of a first embodiment of the buckle 1 according to the present invention. Figure 2 instead shows the buckle in figure 1 attached to a belt 2 for the purpose of forming, for example, a clothing accessory. For the sake of precision it must be underscored that in figure 2 the second plate 20 is depicted as separate from the first 10, while actually fact from the operational point of view the two plates 10 and 20 remain constantly connected as a result of the presence of the stop means. As shown in the aforesaid figures, the coupling means slidingly couple both sides 17, 18 of the first plate 10 to corresponding sides 27, 28 of the second plate, so that the flat portions 11 and 21 of the plates 10 and 20 are mutually facing each other to allow the belt 2 to pass inside the frame 8. More specifically, these coupling means slidingly couple a first side 17 of the first plate 10 to a corresponding first side 27 of the second plate 20 and a second side 18 of the first plate 10 to a corresponding second side 28 of the second plate 20.

Figures 4 and 5 are respectively a sectional front view and an exploded view of the buckle in figure 1. As shown, the coupling means are preferably formed by a first and by a second pair of mating prismatic elements 31 and 32. In detail, each pair of prismatic elements is constituted by a first prismatic element 31 associated with a side 17, 18 of the first plate 10 and by a second prismatic element 32 associated with a corresponding side of the second plate 20. Each pair of mating prismatic elements 31, 32 in substance constitutes a prismatic kinematic pair which extends according to a predetermined coupling direction 100. In particular, the prismatic elements constituting the first pair extend and mate according to a direction parallel (coincident with the coupling direction 200) to the direction along which the elements constituting the second pair extend and mate.

The stop means preferably comprise, for each pair of prismatic elements 31, 32, a pin element 41 interposed along the coupling direction 200 between prismatic elements 31, 32 mutually coupled in order to clamp mutual sliding of these element in a predetermined position.

In the solution shown in figures 4 and 5, the first pair of prismatic elements comprises, as first prismatic element 31, a first track that projects outward from the first side 17 of the first plate 10. This first pair also comprises as second prismatic element 32 a first groove (geometrically mating with said first track) produced on a corresponding first side 27 of the second plate 20. As shown, the first track has an interrupted portion defining in substance the seat 42 (see figures 6 and 7) inside which the pin element 41 is placed. From the point of view of assembly of the buckle 1, the second plate 20 is first coupled to the first plate 10 while the pin 41 is inserted subsequently in a passage produced on the sides of the second plate 20 and positioned transversely with respect to the coupling direction 100 of the two plates 10 and 20.

According to a preferred embodiment of the present invention, also the second pair of prismatic elements indicated above comprises, as first prismatic element 31, a track that projects outward from the second side 18 of the first plate 10 and as second prismatic element 32 a groove (formally mating with the second track) produced on the corresponding second side 28 of the first plate 20. Analogously to the first pair of prismatic elements 31, 32, this track also has an interrupted portion defining a further seat 42 to house a corresponding pin element 41.

Obviously, it must be understood that the above description of the shape of the prismatic elements must be considered exclusively as a preferred and non-limiting embodiment of the present invention. Alternatively, it is in fact possible, for example, for the prismatic elements associated with the sides of the second plate 10 to be formed by one or more tracks while those associated with the sides of the first plate 10 are constituted by corresponding grooves mating with these tracks. Any equivalent shapes and configurations of the prismatic elements must therefore be considered as falling within the scope of the present invention.

Figures 6 and 7 are side views of the buckle 1, which allows the operating principle of the buckle 1, or the manner in which it produces fastening of the belt 2 to which it is attached, to be understood. As is apparent, by virtue of the coupling means the second plate 20 moves with respect to the first plate 10 along the coupling direction (indicated with the reference 100) between a first and a second limit position defined by contact of the pin element 41 with the ends of the seat 42. In particular, at the first limit position the pin 41 intercepts a first end of the seat 42 so that the two flat portions 11 and 21 of the two plates 10 and 20 are at a first distance Hl which allows the user to easily insert the belt 2 inside the frame 8. The second limit position is instead reached when the pin element 41 contacts a second end of the seat 42 opposite the first. As can be seen in figure 7, in this position the two flat portions 11 and 21 are at a second lesser distance H2 than the first distance Hl. In practice, the second plate 20 moves from the first towards the second limit position compressing the belt 2 previously inserted by the user in the frame 8, consequently clamping and fastening said belt.

By virtue of the particular configuration of the buckle 1, the movement of the second plate 20 is produced manually by the user, who can act directly on the second plate 20, moving it towards the first plate 10. With reference to figure 3, to move the second plate 20 the user can also act on the free end of the belt, in substance "pulling" it in the direction indicated by the arrow 50. In this way the belt pushes the second plate 20 into the correct position allowing extremely simple and efficient fastening of the belt 2.

As already indicated above, the buckle 1 comprises first means for connection of the first plate 10 to an end of the belt 2 at the coupling surface 12. In the solution shown in figures 4 and 5, these first means comprise a fixing plate 6 operatively connected to the coupling surface 12 of the first plate 10 to fasten a first end 2 A of the belt 2 to the first plate 10 of the buckle 1. In other words, the first end 2 A is permanently clamped between the first flat portion 11 of the first plate 10 and the fixing plate 6. In the solution shown in figures 3 and 5, for example, the fixing plate 6 is operatively placed in a position facing the second flat portion 21 of the second plate 20. In this solution the first end 2A of the belt 2 is clamped by means of a plurality of fixing pins 7 which permanently connect the fixing plate 6 to the first flat portion 11. The fixing pins 7 pass transversely through the first end 2A of the belt 2 at relative through holes produced in said end.

Figures 8, 9 and 10 are relative to a further embodiment of the buckle 1 according to which the two plates 10 and 20 are mutually coupled to the sides so that the respective C- shaped configurations are operatively positioned one inside the other. Unlike the previous case, the coupling surface 12 of the first plate 10 is not facing the second flat portion 21 but is instead substantially opposite it.

In this solution in question, the first connection means comprise a fixing plate 6 which is hinged at one end to the first flat portion 11 of the first plate 10 so as to rotate about an axis 110 substantially orthogonal to the sides 17 and 18 of said first plate. In greater detail, this rotation axis faces the first flat portion 11 of the first plate 10 on a side that is opposite the side which the second flat portion 21 of the second plate 20 faces. As can be understood from the side view in figure 9, the first end 2A of the belt 2 is clamped between the fixing plate 6 and the first flat portion 11 of the first plate 10 by means of a toothed block 35 associated with the fixing plate 6 to compress the surface of the belt 2 against the first flat portion 11.

This embodiment therefore involves a different method of attaching the buckle 1 to the first end 2A of the belt 2 with respect to the previous solution. The fixing surface 6 is in fact first rotated about the rotation axis thereof (arrow 105 in figure 8) so that the toothed block 35 takes an inert position which allows the first end 2 A of the belt 2 to be positioned against the first flat portion 11 of the first plate 10. The fixing surface 6 is then rotated in the opposite direction to allow the toothed block 35 to perform its clamping action on the belt 2.

This fast and efficient principle of attaching the buckle 1 to a relative belt 2 is evidently advantageous, as it eliminates all operations to perforate the belt. The ease with which the buckle 1 is attached to the end of the belt 2 also provides the user with the possibility of rapidly attaching the same buckle to different belts.

According to the present invention, in order to increase the tightness of the fastening, anti-slip means can advantageously be added to the pressure surfaces of the buckle intended to remain in contact with the belt 2, in order to increase the grip between these and the surface of the belt 2.

These anti-slip means can comprise, for example, a rough membrane which is attached to these surfaces. Alternatively, these surfaces can be coated with a layer of anti- slip paint or be knurled on the surface. Any other functionally equivalent solution must in any case be considered as falling within the scope of the present invention.

Figure 11 is an exploded perspective view of a further embodiment of the buckle 1 according to the present invention, which differs from the buckle in figure 8 in that it has a different system of connecting the end 2 A of the belt 2 to the coupling surface 12 of the first plate 10.

In detail, in this solution this connection is removable so that the end 2 A of the belt 2 can be easily connected and subsequently removed from the buckle 1. This allows a versatile use of the buckle as it can be advantageously attached to different belts 2, for example in terms of length and design.

In the solution shown, this removable connection is produced through first connection means 91 associated with said coupling surface 12 and configured to be connected removably to second connection means 92 associated with the end 2A of the belt 2 for which the buckle 1 is intended.

In the solution in figure 11, the first 91 and the second connection means 92 are respectively constituted by a plurality of male connection elements and by a relative plurality of female connection elements, each of which is fixed on a male element. As shown in figure 11, the male elements 91 can extend directly from the coupling surface 12 of the first plate 10 as a single body or alternatively can be connected to said surface, for example by means of a screw connection. Again in the exploded view in figure 11₅ it can be seen that the female elements are inserted permanently in suitable holes produced in the belt 2 according to the direction indicated by the arrow with the reference 89.

Figures 12 and 12A respectively show a front view and a plan view of the first plate 10 of the buckle 1 in question. In detail, the first connection means comprise three male elements 91 which have a substantially cylindrical shape. The possibility of using a different number of elements and a different configuration thereof must obviously be considered as included in the invention.

Figures 13, 13A and 13B are respectively a plan view and two sectional views of the second plate 20 of the buckle 1 in question. It can be seen that the configuration of the second plate 20 is substantially identical to that of the previously described solutions. In particular, in the sectional view 13 A it can be seen how each pin element 41 is inserted in a recess produced on the side of the second plate 20, orthogonally to the longitudinal direction in which this extends. Through this solution the stop elements 41 are advantageously invisible during normal use of the buckle 1. This solution can also advantageously be provided for the other two embodiments indicated above.

Figure 14 is a view analogous to the one in figures 6 and 7, the purpose of which is to show the moving principle of the plates 10 and 20. In particular, it can be seen how the first plate 20 has a lesser longitudinal extension (intended as measured in the direction of the arrow with the reference 99) with respect to that of the second plate 20. Through this solution, it is possible to maintain the relative motion of the first plate 10 with respect to the second 20 within the dimensional limits of the latter as is evident in the figures. This naturally represents an advantageous alternative to the solution shown in figures 6 and 7 in which the two plates 10, 20 have the same longitudinal extension.

The present invention also relates to a belt 2, which is characterized in that it comprises an end 2A provided with second connection means 92 suitable to be connected, preferably in a removable manner, to the first connection means 91 provided on the coupling surface 12 of the buckle 1 for the purpose of allowing connection of the parts. The connection thus produced between the belt and the buckle forms an accessory, preferably for clothing. With a view to this, figure 15 shows a plan view of the belt 2 connected to the coupling surface 12 of the first plate 10 of the buckle 1.

In an alternative embodiment to the one described above and not shown in the figures, the first 91 and the second connection means 92 could be structured according to a "Velcro" connection method. In particular, this connection includes the use of one or more fabric elements provided with hooks suitable to couple permanently to respective elements having surfaces with loops. In detail, the first connection means 91 could be formed of one or more hooked fabric elements glued to the coupling surface 12 of the first plate 10. In this case, the second connection means 92 could comprise the same number of elements with looped surfaces stitched to the end 2 A of the belt 2.

In a particularly preferred embodiment of the buckle 1, titanium is used to produce the plates 10 and 20 described above. It has been seen that the use of this material makes the buckle extremely solid, reliable and particularly appreciated from an aesthetic point of view. In particular, it has been seen that the use of titanium is particularly advantageous above all to produce coupling means that slidingly connect the two plates 10, 20. In fact, titanium decreases wear of these coupling means, thereby increasing the useful life of the buckle 1. In any case, it must be understood that the parts of which the buckle 1 is formed could also be made of another material besides titanium or alternatively of a non-metal material, such as plastic.

It has been seen that the first embodiment of the buckle (figures 1 to 7) is particularly suitable for prestigious uses, i.e. suitable to be attached to belts made of costly and refined materials. The second and third embodiments (figures 8 to 10) are instead more suitable for use on more widely used belts, such as those with a fabric structure.

The technical solutions adopted for the buckle according to the present invention allow it to fully accomplish the proposed tasks and objects. The buckle thus conceived is reliable by virtue of the use of a limited number of components which can be easily assembled together. The buckle is also easy to attach and is distinguished by an operating principle that advantageously allows operations on the surface of the belt to be limited to a minimum.

In practice, the materials used and the dimensions and contingent shapes can be any according to needs and to the state of the art.
