United States Patent 3,430,274 BED Minoru Ikeda, Tokyo, Japan, assignor to France Bed Co., Ltd., Shibuya-ku, Japan, a corporation of Japan Filed Jan. 5, 1967, Ser. No. 607,565 US. Cl. 181 3 Claims Int. Cl. A47c 17/86 ABSTRACT OF THE DISCLOSURE A bed having side boards and a footboard extending outwardly of the mattress to avoid undue heaviness of the bedclothes covered on a person lying thereon an occasional slipping oif of the bedclothes from the mattress. These boards can be separable from the mattress and detachable into several parts when it is not used.
Background of the invention The present invention relates to bed constructions and more particularly to improvements in bed support assemblies to support a bed mattress.
A conventional bed generally comprises a wooden sup port frame structure to support a mattress, a headboard secured to the support frame and a mattress laid on the support frame. Usually the width of a mattress is substantially equal to or slightly larger than the corresponding dimension of the support frame, so that the side edges of the mattress overhang the frame structure. When a person is to lie down on this type of bed, he first necessarily sits on the bed or directly puts his one leg on the corresponding portion of the bed. Such a posture is very unstable and consequent strong pressure locally applied to the same part of the bed results in early damage and permanent transformation of that part.
The absence of portions of the support frame extending outside the sides of the mattress naturally gives rise to hanging down of corresponding margins of bedclothes such as blankets and coverlets, the width of which is usually greater than the corresponding dimension of the mattress to cause the person lying on the bed to feel heavier these blankets or coverlets. Further, unbalance of hanging portions often causes slipping down of the blankets and the like from the mattress to disadvantage.
A further disadvantage encountered in the conventional bed support assembly comprising a support frame and a headboard is that these parts are secured to each other by means of screw bolts and the like so that assemblage and disassemblage of these parts can not be easily made. Accordingly, transportation and storage of the bed requires a large space and much labor, and bringing it in and taking it out of a room are very troublesome.
Summary According to the invention there is provided a bed which comprises a mattress, a mattress support framework carrying said mattress and consisting of a headboard, side boards and a footboard, said side boards and footboard extending outwardly of said mattress, and a support frame supporting said mattress support framework.

Detailed description In the drawings the same or similar parts are designated by like reference numerals.
Referring to the drawings, and particularly to FIGS. 1, 2 and 3, there is shown a single bed has a mattress 12 laid on a mattress support framework 11 comprising a headboard 13, side boards 14 and 15 and a footboard 16, these boards extending outwardly of the mattress 12. The mattress 12 is supported as in the usual bed construction in a rectangular recess defined by the surrounding boards of the support frame work. The framework 11 is carried by a support frame having four legs 17 in parallel with the floor. The headboard 13 has an upright portion formed at the side remote from the mattress 12 such that a hollow 18 may be formed. The upper surfaces of the side boards 14 and 15 and footboard 16 are arranged to lie slightly below the upper surface of the mattress 12. The upper edges of the side boards 14 and 15 are curvedly cut lower at middle portions. The headboard 13, side boards 14 and 15 and footboard 16 are detachably secured to one another by suitable connecting means.
It is preferred to make these boards from a soft material, for example synthetic resin foam such as polyurethane foam, polyvinyl chloride foam and the like, reinforced by a suitable framework imbedded within the material. Such materials may be readily molded to have a desired configuration and are sufliciently resilient. If desired, the surfaces of the foam may be covered with cloths or synthetic resin sheets to enhance the strength and appearance of the surfaces. Instead of the foam, a synthetic resin such as polyethylene, phenol-formaldehyde resin, urea resin and the like, which are easy to mold may be used depending upon circumstances. Of course, wood may also be used. These materials may be imparted with strength at least suflicient to withstand the weight of the human body by suitable reinforcing means.
As has been previously mentioned, since the edge portions of the bedclothes such as blankets and coverlets are supported on the upper surfaces of the side boards 14 and 15 and footboard 16, not only unduly heavier weight sensation sensed by the human body due to the hanging down of these edge portions of the bedclothes may be avoided, but also the slipping off of these bedclothes from the mattress may be effectively prevented. Also, the side board 14 and 15 extending from both side of the mattress 12 serves as the steps when one transfers his body from the floor onto the bed, so that local damage to or deformation of the mattress may be prevented.
FIGS. 4, 5 and 6 inclusive illustrate another embodiment of the bed according to the invention. In this embodiment the mattress support framework 11 is supported on the support frame 21. The support frame 21 comprises a rectangular frame member 22 and four legs 17 attached thereto. The frame member 22 is made of steel and has an L-shape cross section. As is seen from FIG. 5, there are formed four holes 23 in the horizontal portions of the frame member 22. The mattress support framework 11 is separable in two parts at about the middle of the side boards 14 and 15. The headboard 13 and the footboard 16 are also separable from the corresponding halves of the side boards 14 and 15.
The mechanism involved for connecting separate parts constituting the framework 11 is clearly seen from FIG. 6. Each part of the mattress support framework 11 has a reinforcing hollow steel member 24 having a rectangular cross section contiguously surrounded by an outer member 25 made of wood, synthetic resin or synthetic resin foam. A connecting member 26 is inserted half Way into the reinforcing hollow member 24 and secured thereto by suitable means. Each part of the mattress support framework 11 may be connected to the adjacent part by inserting portion of the connecting member 26 extending from the associated reinforcing member 24 into the hollow of the counterpart reinforcing member 24 of the adjacent part to complete the assemblage of the support framework 11. If it is desired to completely prevent the accidental detachment of the connecting member out of the mate reinforcing member, the telescoped portion of the connecting and reinforcing members may be secured by such auxiliary means as set screws traversing the section of the telescoped portion. The reinforcing member 24 is provided at its lower side with downwardly extending stud bolts 27 at predetermined positions for insertion into holes 23 (FIG. 5) formed in the support frame 21 to secure the mattress support framework 11 to the support frame 21 preferably by fastening nuts 28.
This embodiment permits easy disassemblage into mattress, mattress support framework and support frame, with mattress support framework being further separated into several parts, for transportation and storage, so that space and costs for spacing and subsequent transportation and storage may be considerably reduced. Conversely, the assemblage of the separated parts can be readily made. When ssembled, this bed also affords mattress protection and comfortability as in the previous embodiment shown in FIGS. 1 to 3.
1 FIG. 7 illustrates a modification of the mechanism involved in the connection between the support frame and the mattress support framework having reinforcing members 24 and legs 17. In this variety the mattress support frame work 11 is secured to the side portion of the support flame 21 by means of screw bolts 27 and the legs 17 are secured to the underside of the reinforcing member 24 by means of stud bolts 29. With this construction the mattress support framework 11 can have a greater strength to withstand the load applied thereon and also can have suificient lateral dimensions.
It is to be understood that the foregoing description of specific examples of this invention is made by way of example only and is not to be considered as a limitation on its scope.
