16 Claims.. (Cl. 155-181) The present invention relates to furniture such for example aschairs, divans, couches, beds, or vehicle seats, having a novel box spring structure, and more particularly to a novel box spring structure which may be built into such furniture or which may be used as a separate unit therewith in the usual manner.

in the past such box spring units have generally been made by fabricating a rectangular wooden frame and then mounting a group of springs on the frame in various ways. The use of wooden frames for box springs has long been considered undesirable from a manufacturing standpoint since the accumulation of the necessary quaniity of wood in a factory creates a substantial fire hazard and since workmen are frequently injured by splinters or slivers when handling wooden frames and often cut themselves when they .are attempting to cut the Wood. Furthermore, wooden frames are usually constructed at one plant and then shipped to various box spring assembling plants and since wooden frames cannot easily be shipped in a knocked down condition the shipping and handling charges are unnecessarily excessive. Another undesirable characteristic of wooden box spring structures having Wooden frames is that they may be unduly noisy. This results from the fact that the wooden frames tend to amplify spring noises and also from the fact that the joints of the wooden frames may loosen and begin to squeak. It has been suggested that the wooden frames may be replaced by metal frames but such heretofore suggested metal frames have been relatively heavy, complicated and expensive so that wooden frames are still generally used.

An object of the present invention is to provide a novel box spring structure of the above described general type, which structure is provided with a metal frame that is relatively light in Weight, of simple construction and inexpensive when compared to Wooden frames heretofore use Another object of the present invention is to provide :i novel metal frame for a box spring structure, which frame may be easily shipped in a knocked down co-ndition and may be relatively easily assembled together.

Still another object of the present invention is to provide furniture incorporating a novel box spring structure of the type described in the preceding paragraphs, which furniture may also include supporting legs and/ or a back rest connected to the frame of the box spring structure in simple, economical, and rigid manner.

A further object of the present invention is to provide a novel box spring structure of the above described type wherein the springs are retained in assembled relationship with each other and with the metal frame in a simple and economical manner.

A more specific `object of the present invention is to provide a novel box spring structure having a metal frame of the above described type, which structure also includes a covering fabric or ticking anchored to the metal frame in a simple and economical manner.

Referring now more specically to the drawings where'- in like parts are designated by the same numerals throughout the various figures, a couch or daybed 30 is shown in Fig. l for the purpose of illustrating an important application of the present invention. The couch 30 includes a box spring unit 32, a plurality of supporting leg structures '34 connected to the box spring unit inthe manner described below, a back rest 36, and support arms or brackets 38 and 40 which are also connected to the box spring unit. A mattress 42is disposed on the box spring unit and this mattress may be of inner spring or foam rubber construction or of any other known construction and if desired the single mattress 42 may be replaced by a plurality of cushions, now shown.

In accordance with the present invention the box spring unit includes a metal frame 44 shown best in its entirety in Figs. 2 and 4. The metal frame 44 includes a longitudinally extending side frame member 46 having integral end portions 48 and 50 bent inwardly to provide a part of the frame ends and a second longitudinally extending side frame member 52 also having inwardly bent end portions 54 and 56. A plurality of transverse frame members S8, 60, 62 and 64 extend between and are secured to the side frame members in the manner described more fully hereinbelow and the corners of the frame structure are braced by diagonal frame members .66, 68, 70 and 72.

In accordance with a feature of the present invention all of the frame members of the frame Vstructure 44 are formed from lengths of sheet metal which have been rolled to provide the particular generally channel-shaped transverse cross section shown best in Fig. 5. More specifically, it will be seen by referring to Fig. that each of the frame members is formed so that it includes a generally vertically extending web portion 74 having upper and lower horizontal llanges 76 and 78. In addition, the web portion is formed with a reversely facing channel section, or in other words, the web portion 74 is formed with relatively short ' horizontal sections 80 and 32 joined by a bottom section 84. This structure gives the relatively light weight sheet metal frame members great strength and rigidity so that the frame structure 44 is lighter and stronger than it would be if it were constructed from wood. Furthermore, substantial economies may be effected by utilizing the metal frame structure 44 since 'all `ofgthe Iframe members are cut from the same channel stock and they may be easily shipped in Vknocked down or disassembled condition to a factory where they are secured together. Y

As indicated above the side frame members 46 and 52 and their Aassociated inturned end portions are each formed lfrom a single piece of channel stock, which stock is formed so as to provide the frame structure with corners that are not only neat in appearance but also are strong and rigid, Since all of these corners are identical only the cornerbetweenthe side Vframernember `46 and its end (portion 50 will be described in detail.

This'corner is formed as shown best in Figs. 5, '6, 9

bracing the corresponding flanges of the side frame memi ber. During this folding operation the material of the channelV portion 84 is looped or bent into a fold'86 which substantially strengthens the corner. At the same time the material of the horizontal channel portion 80 at opposite sides of the slit is folded upwardly in the form of tabs 87 and 88 and it will be understood that the material of the horizontal channel portion V82 at the opposite sides of the slit will be similarly formed. After the end portion 50 hasbeen bent to the position illustrated, Vthe upper flanges of the side frame member and the `end portion are spot welded together as indicated at 90 and the lower flanges are similarly spot welded together as indicated at 92.

After the side frame members 46 and 52 and their associated .end portions have been formed in .the manner just described the end portions 48 and 54 are joined together by the means shown best in Fig. 8 and the end portions 50 and 56 are similarly joined together as will beundersto'od The end Vportions 48 and 54 are butt welded as indicated at 94 in Fig. 8 and a sheet metal reinforcing member 96 having the same cross sectional shape as the web portion V74 is positioned within and welded to the end portions 48 and 54 at a plurality of spot welds 98. Thus, the junction between the end portions 48 and 54 has a smooth neat external appearance and the particular cross sectional shape of the end portions and the reinforcing member 96 gives the junction great strength.

The diagonal frame member 68 is secured between the side frame member 46 and its associated end portion 5l? in the manner shown best in Figs. 4, 5, 6 and 7. The ends of the diagonal member 68 are cut at an angle, as indicated, so that they may be inserted fully within the llanges of the side frame member 46 and its associated end portion. Since all of the frame members have the same cross sectional dimensions it is necessary to bend the flanges of the side member and the end portion and/or the flanges of the diagonal member to permit assembly of the diagonal member in the manner just set forth and the light weight of the sheet material stock permits such bending to be readily accomplished. In addition to cutting the ends of the diagonal framc member 68 at an angle the web portion ot this frame member, at each end thereof, is notched as indicated at 100 and 102 in Fig. 7 to permit the diagonal member to be assembled over the sections 80-84 of the side frame member and the end portion 50 and also to provide tabs v104 which are bent to lie against the sections 84 of the side frame member and the end portion 50. After the diagonal frame member 68 has been assembled the tabs 104 are spot lwelded Yto the side 'frame member 46 and its end portion as indicated at 106 and the upper and lower flanges of the diagonal frame member are spot welded as indicated at 108and 110 to thecorrespending flanges of the side frame member 46 and thc end portion Si). While only the end portion of the diagonal frame member 68 connected to the side frame member 46 has been shown in detail it is understood that the opposite end of the .frame memberis constructed in a similar manner for connection to the end portion 50 and it is further understood that the remaining diagonal frame members are identical to the frame member 68.

The transverse frame members 58-64 are also inserted within and spot welded to the upper and lower flanges of the side frame members. Since each end of all of the transverse frame members is connected to its associated side frame member in the same manner only the connection of the transverse frame member 62 to the side frame member 46 will be described in detail. Referring particularly to Figs. 5 and 6 it isseen that the frame member 62 is inserted between the flanges 76 and 78 of the side frame member until it abuts against the section 84 of the side frame member. It should be noted that the flanges 76 and 78 are substantially longer than the horizontal sections 80 and 82 whereby the flanges of the side frame member may be spot welded to the corresponding flanges of the transverse frame member as indicated at 112. The connection `between the transverse frame member'and the side frame member is further strengthened and rigidified by means of an angle bracket 114 which is spot welded as at 116 and 118 to the sections 84 of the transverse frame member and side frame member respectively.

Referring particularly to Figs. 2, 3, and l0 it is seen that a plurality of longitudinally extending llat metal strips 120 are spaced from each other transversely across the top of the frame structure 44. These strips are spot welded at their opposite ends to the ends of the frame structure in the manner indicated best at 122 in Fig. 10 and they are also spot welded to the diagonal frame members and the transverse frame members as indicated at 124 and 126. Thus, the strips 120 serve to further strengthen and rigidify the frame structure. In addition, each of the strips 120 serves to support a row of coil springs 128. In this embodiment, "each of the springs 128 is of inverted generally frusto-conical shape with its bottom end coiled tightly together as shown best in Fig. 11. The tight bottom -coils of each spring are slipped over one of the strips and resiliently grip the strip for retaining the spring and the strip in assembled relationship. In addition, each of the strips 120 is provided with a series of upwardly struck tabs 130 with each of the tabs located to project within one of the springs as shown in Fig. l1 and retain the spring in the desired position upon the strip. With this structure it has been found that the springs are sufficiently supported so that their upper ends need not be tied together or otherwise positively held in place.

The box spring unit 32 includes an insulator 132 of any known construction overlying the springs 128. A pad 134 of sisal or cotton or any other suitable material is placed over the insulator and the assembly is enclosed bya suitable fabric covering 136. The fabric covering extends downwardly around the metal frame and is secured to the frame in the manner shown in Fig. 17. Thus, the fabric is wrapped around the lower ange 78 of the frame side and end members and a generally U- shaped spring clip 138 is snapped over the ilange and fabric. The clip includes a plurality of inwardly and rearwardly projecting struckout teeth 140 which dig into the ange and positively prevent disassembly of the clip. While only one clip 138 is illustrated it is understood that a plurality of these clips should be spaced along l the flange 78 entirely around the frame structure.

In Figs. 18 and 19 there is shown amodiiied structure for securing the covering fabric 136 to the frame. In this embodiment the clips 138 are eliminated and a plurality of spaced teeth 142 are struck from the flange 78 and project into the fabric. Preferably the margin of the fabric is folded into at least a double thickness as indicated at 144 to prevent the teeth from tearing the fabric.

In Figs. 12, 13, 14 and 15 there is illustrated a modified box spring structure which is similar to the structure described above as indicated by the application of identical numerals with the suiiia added to identical parts. This embodiment differs from the structure described above in the manner in which the springs are supported. The above described elongated metal strips 128 'have been replaced by a grid of longitudinally extending wires 146 and transversely extending Wires 148, which wires are connected to the frame by passing end portions thereof through suitable apertures provided in thev frame as shown best in Fig. l2. At every crossing of the wires 146 and 148 they are formed with mating undulated portions as shown best in Fig. 14. With this structure one of the coil springs may be connected to each crossing of the wires 146 and 148 by passing the end of the spring rst under the wire 148, then over the wire 146, then under the wire 148 again, and finally over the wire 146 in the manner illustrated.

As indicated in Figs. 12 and 15 the transverse wires 148 may be omitted at the positions occupied by the transverse frame members and the transverse frame members may be'modied to perform the function of the omitted wires. This modication is accomplished by bending the upper flange of each transverse frame member such as the frame member 58a into a vertical position and then reversely folding the margin 150 ofthe flange. As shown best in Figs. 12 and l5, the resulting double thickness of the transverse frame member 58a projects above the plane of the wires 146 and therefore the upper edge of the transverse frame member is notched as at 152 to receive each wire 146. In addition, the transverse frame member is provided with a pair of apertures 154 and 156 located on opposite sides of each of the wires 146, which apertures are adapted to receive a coil spring in the manner illustrated so that the transverse frame member cooperates with the longitudinally extending Wire 146 for mounting spring.

f bracket in anysuitable manner.

In Fig. 16 there is illustrated a modified form of the structure illustrated in Fig. l5. ln the embodiment of Fig. 16 the transverse frame member 581; instead of being modified into the form shown in Fig. 15 supports a. sheet metal angle member 1538 which is spot welded thereto. The upwardly extending ange of the angle member. is provided with a slot 152b and apertures 154b and 1561; which have the same function as the corresponding elements shown in Fig. 15. It is of course understood that a plurality of slots and associated apertures will be spaced along the length of the angle member to accommodate a plurality of wires 146 and a plurality of springs.

The support leg structure 34 is shown in Figs. 1 through 3, 10 and 22 through 25. The support leg structure includes a `bracket having a base and a pair of iiat vertically extending and angularly disposed fingers 162 and 164. The base and lingers are preferably formed from a single piece of heavy sheet metal. As shown best in Figs. 22, 23 and 24 the bracket is connected to the metal frame 44 by inserting the fingers 162 and 164 through suitable slots formed in the metal frame; More particularly, the

lower flange 78 and the upper and lower horizontal sections 88 and 82 of each of the frame side members and end portions are respectively provided with narrow slits 166, 168 and 170 for receiving one of the ngers 162-- 164.y Preferably the lingers are slightly tapered toward their outer ends and are substantially thicker than the width of the slits, whereby the fingers may be forced or driven through the slits and tightly held in place. Preferably the fingers are driven into the slits after the fabric covering 136 has been applied to the frame so that the fabric will be drawn into the slit 166 around each finger as shown in Fig. 22 and thereby present a smooth and neat appearance. While the fingers 162 and 164 of the bracket will normally be tightly gripped and held in position it may be desirable to positively lock the bracket against accidental loosening by passing screws 172 through suitable apertures provided therein and threading the screws into the frame structure. In the illustrated embodiment a leg 174 is secured to the bracket base 160 and this leg consists of a generally U-shaped metal rod. However, it should be understood that the leg 17 4 may be of any known construction and may be connected to the With the structure just described it is seen that the particular cross sectional shape of the frame members enables the support leg brackets to be applied to the frame in an extremely simple and economical manner while at the same time the connection between the leg bracket and the frame is strong and free from looseness.

In Fig. 26 there is illustrated the back rest supporting bracket 48. This bracket is connected with a frame structure in much the same manner as the leg bracket described above. More particularly, the bracket 48 includes a heavy sheet metal Ibase 176, a pair of fingers 178 and 180 eX- tending upwardly from the base, and a back rest support arm 182 extending upwardly from the base. The fingers 178 and 188 are adapted to be inserted through slits in the frame structure, which slits are identical to the slits 166-170 described above and theingers 17S and 180 are identical to the fingers 162 and 164 of the leg bracket except that they are disposed in the same or parallel planes rather than in angularly disposed planes. The back rest support brackets 38 which are partially shown in Fig. l may be identical to the bracket 48 or they may include arms integral with or connected to the base 168 of one of the leg brackets. It is understood that arm rests, not shown, may also be mounted to the frame 44 in the same manner as the `back rest. Such arm rests as well as the `back rest may be provided by a metal frame essentially the same as the frame 44 covered with suitable padding and either with or without suitable spring means anchored thereto.

,As will be understood the fabric covering 136 which is 2,1841 ,nos

stretched tightly over the outwardly facing surface of-the sheet metalframe may tend to sag into the inwardly formed channel or recess inthe outer surface of the frame structure. This tendency of the material `to sag into the channel is particularly noticeable at the corners of the metal frame and .therefore the corners are preferably filled with any suitable padding material as indicated at 184 in Fig. 24. in addition, it may be sometimes desirable to filllthe channel with the padding material as shown in Fig. 20. The channel may be filled with -the padding material all the way around the frame or only for example, along the front of the frame.

In Fig. 21 there is illustrated the cross section of a channel member 186 which may be used in lplace of the channel members described above. The channel member 186 includes an outer vertical web 188 having upper and lower integral horizontal flanges 190 and 192. The channel member 186 includes a second part having vertical sections 194 and'196 which are offset vfrom another vertical section 19S by short horizontal sections 200 and 202. The vertical sections 194 and 196 are spot welded as indicated at 204 to the vertical web 188 so that the two sections of the channel member combine together to provide the channel member with great strength and rigidity without an undue increase in weight. vIt should be noted that the cross sectional shape of the channel member 186 is essentially the same as the Vcross sectional shape of the channel member described above and shown for example in Fig. 20 so that the 'advantages of this cross sectional shape in facilitating rapid and economical fabrication of a strong light weight metal frame 'are retained. Besides being substantially stronger than the previously described channel members, the channel member 186 has the further advantage of presenting a smooth outer surface so that the extra step of filling the inwardly extending channel of the structure shown in Fig. 20 with the padding 184 may be eliminated.

From the above description it is seen that the present invention has provided a novel box spring structure which may be used in a conventional bed or which may equally well be built into a couch or daybed or similar piece of furniture.

As will be understood, the term furniture as used herein in the description and claims includes any and all assemblies with which the Vnovel box spring structure of this invention may be used, such for example, either back, arm or cushion portions of vehicle seats, couches, divans or chairs, and beds wherein the box spring structure is either separable or with attached legs such as in Hollywood bed types and the like. It also is seen that the present invention has provided a novel box spring structure having a metal frame which may be more easily and economically fabricated than wooden frames heretofore used and which is relatively light in weight and may be economically shipped in a knockdown condition. In addition, it will be appreciated that the use of the metal frames of this invention enables the frames to be fabricated readily in various sizes and shapes and permits frame portions to be added to a frame whenever desired. More specifically, it is seen that the present invention has provided a novel metal frame which includes light weight sheet metal members having a particular cross sectional shape such that the frame members may be easily assembled and provide a strong and rigid frame structure and in addition the frame members are particularly adapted for easy connection to leg or back rest support brackets and the like. Furthermore, it is seen that the present invention has provided a novel box spring structure wherein the springs and covering fabric are connected to the novel metal frame in an extremely simple and economical manner.
