Application January 2S, 1953, Serial No. 333,691

11 Claims. (Cl. 5 285) The present invention relates to bed frames adapted to support spring units and mattresses.

A general object of the present invention is to provide light weight bed frame structures which are simple and sturdy of construction, with the parts thereof few in number and readily and economically manufactured on a mass production basis and which permit simple assembly in an unusually simple manner by unskilled purchasers.

A more specific object of the present invention is to provide such bed frame structures in the form of four corner leg bracket units and four L-shaped angle rails which may be easily bolted or otherwise fastened together to produce bed frames in which the legs avoid kick interference and which permit spring units to be readily mounted thereon and removed facilitating assembly and disassembly and knockdown storing.

Another object of the present invention is to provide in such bed frames corner leg bracket units which dictate anchorage thereto of L-shaped angle side rails in outwardly canted positions, and which in Hollywood ernbodiments permit the vertical flanges of the L-shaped angle end rails to extend downwardly out of the way in overlapping relation to end portions of the brackets.

A further object of the invention is the provision of such bed frame structures in either Hollywood or head board style which are readily made and permit eiiicient use thereof.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements and arrangement of parts, which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.

Referring to the drawings, in which like numerals identify similar parts throughout, it will be seen from Figs. l to 7 incl. that an embodiment of the present invention may be of the Hollywood type consisting generally of four corner bracket units 20-20, two side rail units 21, 21 and two end rail units 22, 22. Such a bed frame structure has neither a head board nor a foot board, and thus the corner bracket units 20-20 may all be of like construction.

As is best seen from Figs. 3, 4 and 6, each corner bracket unit 20 may comprise a lateral support plate 23 having dened thereon a pair of elongated, rail-supporting top portions 24 and 25 substantially normal to each other and extending toward a corner portion 26 which is preferably right angularly shaped, as shown. The railsupporting top portions 24 and 25, respectively, constitute seats for an end of each of a side rail 21 and an end rail 22. The seat 25 is preferably, but not necessarily, defined by a pair of laterally spaced, longitudinallyextending, relatively at lands 27 and 28. The seat 24 preferably has a longitudinally-extending land 29 provided only along the inside edge thereof, which preferably, but `not necessarily, extends only to the land 27. The side edge of the support plate 23 is provided with an upstanding flange 30 laterally spaced from, and extending substantially parallel to, the land 29, and to which the lands 27 and 28 preferably extend. A lateral cross web 31 extends diagonally across between the seat portions 24 and 25, and preferably forms an integral portion of the support plate 23.

As is best seen from Figs. 3 and 4, a downwardly extending yleg 32 is made integral with the support plate 23 and is set back au appreciable distance from the corner 26 to beneath the web portion 31 of the support plate, so that the edges of the bed at the foot, head and sides will extend appreciable distances beyond the legs to minimize kick interference. Each leg 32 is provided with strengthening side ribs 33, 33 and the connection of the base of the leg with the support plate 23 is strengthened by additional fins or ribs 34 and 35. As is best seen in Fig. 4, the upstanding side flange 30 preferably extends downwardly past the support plate 23 to provide a skirt 36 with which the rib 3S is merged to bridge between that skirt and the leg 32. The bottom end of each leg is preferably provided with a hole or socket 37 to receive the stem of any suitable caster unit, such as that illustrated at 3S in Fig. 4.

The side and end rails 21, 21 and 22, 22 are provided in the form of lengths of L-shaped metal angle stock. Each side rail has a laterally extending bottom flange 39 and an upstanding side flange 4t) disposed substantially at right angles to each other. Each end rail has a laterally extending flange 41 and a downwardly extending flange 42, also disposed substantially at right angles to each other.

As is best seen from Figs. 5, 6 and 7, each of the seats 24 and 25 preferably is provided with a pair of longitudinally-extending and longitudinally-spaced, elongated slots 43, 43. Both ends of the bottom flange 39 of each side rail 21 and those of lateral flange 41 of each end rail 22 are provided with pairs of longitudinally-spaced bolt holes through which bolts t4-44 are projected down through slots 43-43 to receive beneath support plate 23 fastening wing nuts Liii-55, demountably to attach the side and end rails to the corner bracket units. Employment of slots 43-43 is preferred to permit easy adjustment of the parts relative to each other and to avoid the necessity of careful location of holes to be aligned for reception of the bolts. Of course, other suitable fastening means may be employed preferably of a demountable nature, to connect the ends of the side and end rails to the corner bracket units.

The embodiment of the invention illustrated in Figs. 1 to 7 incl. may be marketed in knockdown form which permits compact packaging, simplifying storage and shipping. The parts preferably are made from light-weight material, such as aluminum alloy, from which the corner bracket units Ztlmay be readily cast. The side rails of course may be made as cut-off lengths of rolled or cast angle stock. Thus, such a bed frame structure may be easily and compactly stored by the purchaser in a closet, or the like. An unskilled purchaser readily may assemble the parts by following simple directions with insertion of the bolts in the holes and the slots and threading thereon the wing nuts.

It will be found in the assembled bed frame that the land 29 slightly tilts the bottom flange 39 of each side rail 21 to slope it downwardly and outwardly toward the bracket side flange 30. The resulting small angle of tilt is indicated at 46 in Fig. 6. This causes the upstanding flange 40 of each side rail 21, which is lapped to the inner side of the bracket flange to extend obliquely upwardly and be canted outwardly, the angle of canting being indicated at 47 in Fig. 6. As a result, the distance between the top edges of the side rail flanges 40, 40 is somewhat greater than the distance between their bottom portions where they connect with the bottom flanges 39, 39. Thus, When the bottom portions of angle flanges 40, 40 are spaced apart a distance suicient readily to receive therebetween the bottom structure of a spring unit, such as a box spring, no binding will be experienced in mounting such a spring unit on the bed frame and in removing it. Facilitating such reception and removal of the spring unit in that manner is an important feature of the present invention. it will be noted from Figs. 6 and 7 that preferably the top surface 48 of land 29 is sloped downwardly and outwardly toward the base of the bracket side flange 30 so as to provide an appreciable bearing between the land top surface and the bottom of the inner edge of the rail bottom flange 39. Of course, if desired, the seat 24 may be provided with a wide sloping seating surface for the same purpose, and the land 29 may have a at top surfacewhich will have at least line contact with the bottom of the inner edge of rail flange 39 to tilt it upwardly. All such rail-supporting structures constitute outwardly and downwardly sloping seating means to cant outwardly the rail upstanding flange 40.

As is best seen in Figs. 4, 5 and 6, it is preferred that the end rails 22, 22 be mounted with their unperforated flanges 42, d2 extending downwardly so as to overlap the end portions of the corner bracket units 20-20. There is little tendency for spring units, mattresses and bedding to shift in use longitudinally on a bed frame, and thus it is not necessary to have upstanding end rail structure, such as side rail flanges 4i), 4t), to prevent such shifting. As a result, reception and removal of the spring unit from the bed frame may be facilitated by such orientation of the end rails, and, of course, the necessity of also canting them outwardly is eliminated.

Although it is preferred to employ the two laterally extending lands 27 and 28 of substantially uniform height upon which the end rail flange 41 is to seat, their use is not necessary and the seat 25 defined thereby may also be of uniform thickness throughout. lt is preferred that the seat 25 overlap the end of the seat 24 as shown in Fig. 6 and extend substantially to the bracket side flange 36 so that the latter may, if desired, give some support to the end edge of the end rail flange 41.

The present invention may be embodied in a bed frame structure of the head board type as illustrated in Figs. 8 to 13 incl. In such embodiment the bracket units 120, which are to be located at the corners of the head of the bed differ'from the bracket units 20, 20 of the embodiment illustrated in Figs. l to 7 incl., as indicated hereinafter. As is best seen in Fig. l0, the side flange 130 is increased in height at Sti in the vicinity of the extreme corner 126 there to merge with a similar elevated head and flange portion 51. Head end flange 230 is similar to side flange 130 but it has provided in its elevated portion 51 a pair of elongated slots 52, 52 through which bolts may be received to fasten thereto any desired head board unit, such as that indicated at 53 in dotted lines in Fig. l() and full lines in Fig. 8. An upstanding lug 49 on lateral support plate 123 defines an outer end of the seat for one end of the head rail 122. Such structure dictates mounting of the head end rail 122'with one perforated end of its lateral flange 41 bearing upon the seat 125 and its other flange 42 extending upwardly and lapped to the inside of bracket upstanding flange 230. The end edge of lateral flange 41 of the head end rail 122 may abut against the stop lug 49 which prevents this rail from extending outward therebeyond in all positions of adjusted width.

As best seen in Fig. 10, the leg element 132 of head board leg bracket unit 120 is modified to conserve casting metal while retaining the necessary strength. The upper portion of the leg is in the form of a C-shaped web 54 merged at the top with lateral plate 123 on which seats 24 and 125 are formed. The C-shaped web 54 is closed off at its bottom 55 by a cross wall which is merged with a relatively thick bottom leg portion 56 having strengthening ribs 133, 133.

Different foot bracket units may be employed with such head bracket units 120, 120, as is illustrated in Figs. 12 and 13. Each of such foot bracket units 220, 220 may have a curved corner 226, rather than a right angle corner such as 126 of head bracket unit 120. The side and end upstanding flanges are merged with a curved corner which together provide a curved upstanding flange' In all other respects the features of each foot bracket unit v 220 and the mounting thereto of the side and end rails 21, 21 and 122 are similar to those of each head bracket unit 120, except that stop lugs 49, 49 preferably are provided for both the side and end rail seats 124 and 125.

As illustrated in Figs. 14 to 17 incl., a modified form of the present invention as embodied in the Hollywood type of bed may comprise four corner bracket units 320, 320, two of which are alike and the other two being similar but reversed with respect to the side and end seats and the side flanges. The main body of bracket 320 has a curved outer corner 326 defined by an upstanding curved flange 430. Preferably, curved flange 430 is of appreciably less height than the curved flange 33() of bracket 220 except along side rail seat 224 where it is increased in height to provide flange portion 530. Seat 225 for an end of the downwardly oriented end rail 22 is foreshortened, as shown and preferably is provided with inner and outer laterally-spaced lands 127 and 128, extending to the edge of a socket 56 defined on the outer side by flange 430 and on the inner side by another curved flange 57 and end walls 58, 5S at the outer ends of rail seats 224 and 225. The deep socket 56 also foreshortens side rail seat 224 which is additionally defined at its outer end by an upwardly extending stop or abutment rib 59 on the inner face of side flange portion 530 against the outer edge of upstanding flange 40 of side rail 21 may abut.

The socket 56 is provided for conservation of material without sacrifice of strength and the socket side walls 430, 57, 58 and 58 merge at the bottom of the socket with cross wall structure from which integrally extends a solid leg portion 156 carrying strengthening side fins merged with socket end walls S8, 58, as best seen in Fig. 14. Curved flange 430 terminates adjacent the outer end of end rail seat 225 in a substantailly vertical abutment shoulder S9 where depending skirt 136 is set back to a depth substantially the thickness of the flange 42 of end rail 22. Thus the outer face of that rail flange 42 will lie substantially flush with the outer surface of the curved portion of outside flange 430 forming the outer Wall of socket 56 which forms a hollow top portion of the leg structure.

The land 129 of the Figs. 14 to 17 incl. embodiment may be merged at its inner end with a tapered cross rib 60 providing a wider oblique outwardly sloping seat for side rail flange 39. Obviously seat 224 may be formed by a wide land having a sloping top surface extending completely across to flange 531B.

As indicated in Fig. 18 one may provide an upstanding abutment flange 61 flanking the sloping top surface 48 of inner side seating land 29, to flank the inside edge 62 of the rail bottom flange 39. As a result, when bottom flange 39 of side rail 21 is seated upon its seat 324 with upstanding flange 46 lapped to the inner face of bracket flange 30, the inside edge 62 of that bottom rail flange will abut against seat flange 61 so that the latter may limit lateral movement of the rail.

It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
