- \LLIARD DESENNETT ATTORNEYS United States This application is a continuation-impart of application Serial No. 103,776, filed April 18, 1961, now abandoned, and relates to a wall bed structure.

The primary object of the invention is the provision of a generally improved wall bed structure which utilizes a regular box spring and mattress, and which is supported on a wall panel, which, when the bed is pivoted into the wall recess, matches and is flush with the rest of the wall, so that the presence of the bed structure is concealed, the bed structure being thereby suitable for installation in living areas wherein space is at a minimum, and/or wherein extra sleeping accommodations for occasional or regular use are required, which do not interfere with or detract from the decorative schemes of the areas, as in family dens or living rooms, hotel and motel rooms, dormitories, and trailers.

Another object of the invention is the provision of a wall bed structure wherein a torsion bar assembly is provided which enables the bed to be easily operated between storage and use positions, and wherein the bed, once started out of its wall recess, subsides gradually to its use position on the floor, whereby no substantial strength or skill is required, and exertions such as might be injurious to elderly or ill persons are eliminated.

A further object of the invention is the provision of a wall bed structure wherein a locking means is provided which is actuable upon execution of the movement of the bed to the use position to releasably hold the bed in fixed position upon the adjacent portion of the floor surface.

A still further object of the invention is the provision of a wall bed structure wherein a releasing means is operatively connected to the locking means for retaining the locking means in the position releasably holding the bed in the fixed position upon the adjacent portion of the floor surface and which releasing means is releasable at the will of the user of the bed.

A still further object of the invention is to provide a wall bed structure which utilizes a bed assembly including a box spring and a mattress superimposed upon and fixed to a bed frame, the mattress and box spring being detachably secured together by cooperating releasable attaching means on the spring and mattress and of a construction such as to permit the tucking of a sheet between the complemental side edges of the spring and mattress when said cooperating means are in attaching relation and the bed assembly is in use position, and permit re-positioning or replacement of the mattress when said cooperating means are in detached relation and the bed assembly is in use position.

A still further object of the invention is the provision of a bed structure of the character indicated above which is simple in construction and is composed of a small number of simple and easily assembled parts, and which is devised to be manufactured in rugged, serviceable, and well-finished forms at substantially lower cost than present wall beds.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

R ferring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated bed structure comprises a wall 10 of a living area, the wall being formed with a vertically-elongated rectangular recess 12, which includes a portion 14 of the room floor F as a bottom wall, has a perpendicular back wall 16, parallel perpendicular side walls 18, and a horizontal top Wall 2%. As show-n in FIGURE 1, the recess 12 extends from the floor F to a point spaced above the floor F and is of an area to receive a bed assembly when in an upstanding position. Arranged in a position of use is a non-folding bed assembly designated by the numeral 22, the assembly being disposed, FIGURE 1, so as to extend along the floor F with the head 44 contiguous to and in alignment with the recess 12 and the foot 64 spaced longitudinally outwardly of and in alignment with the recess 12.

The bed assembly 22 comprises a bed frame 24, which is composed of upper and lower frame members 26 and 23, respectively, which are preferably made of square tubing, and are spaced and connected together by means of longitudinallyspaced intermediate vertical elements 39 and outer vertical corner elements 32. In any construction of the frame 24, the same is to be strong enough and rigid enough to resist all stresses and strains, including twisting, to be expected in its use and operation. A crossbar 3-!- extends between and is fixed to the side members 27 of the upper frame member 26, midway between its ends.

The lower frame member 28 reaches longitudinally inwardly beyond the upper frame member 26, as shown in FIGURES 4 and 5, and a wall panel 38 which reaches outwardly beyond the outer end of the frame 24, underlies and is fixed to the underside of the lower frame member 28, as by means of screws id.

The head 44- in the form of a headboard is fixed to the inner end of the bed frame 24.

At a location longitudinally outwardly of the outer end of the bed frame 24, the foot or footboard 64 is fixed upon the wall panel 53. The footboard 64 preferably comprises a perpendicular wall 66 which is fixed to and rises from the upper surface of the wall panel, to a level above the frame 24. The well 66 is preferably cornerbloclred relative to the Wall panel, as indicated at 63, and an outwardly-declining finish panel 7%) is secured to and extends downwardly from the upper end of the wall 3 66 and is suitably secured, at its lower end to the wall panel 38. Transversely-spaced operating handles 72 are suitably fixed to the outer surface of the finish panel 79.

The bed frame 24 is transversely pivoted, at its inner end, to the outer end of an anchor frame 74, located on the fioor portion 14 within the wall recess 12, and constituting the means connecting the head 44 of the bed assembly 22 to the anchor frame 74 for movement of the assembly between the use position and an upstanding position of storage within the recess, as shown in FIG- URE 5. The anchor frame 74, as shown in FIGURE 2, includes an elongated side member 76 which extends along the inner end of the bed frame 24, a tray-like end member 78 projecting transversely from each end of the side member 76, and a connecting member 39 extending between and having its ends secured to the end members 73. To the side member 76 of the anchor frame 74 is pivoted, as by hinges 38, the inner end of the bed frame 24. The anchor frame 74 is fixed to the floor portion 14 by means of screws 84 extending through the end members 78 and threaded into the floor portion 14.

A torsion bar assembly, generally designated 104, is provided for controlling and assisting in the movement of the bed assembly 22 between the use position and the upstanding position of storage within the recess 12, the torsion bar assembly being so constructed as to be under maximum load condition when the bed assembly is in the use position, and under minimum load condition when the bed assembly 22 is in the storage position. The torsion bar assembly 164 comprises a pair of

straight bars

110 and 112 arranged so as to extend in criss-cross relation with the adjacent ends secured to the complemental ends of the anchor frame 74 and the bed frame head 44.

As shown in FIGURE 3, the torsion bar 116 terminates, at its ends, in oppositely-directed

arms

114 and 116, which are initially disposed at right angles thereto. The arm 114 is stressed and is extended into the related side member 27 of the upper bed frame member 26, and the arm 116 is stressed and extends along the adjacent end member 78 and is suitably fixed upon the end member 78 of the anchor frame 74 by means of a plurality of spaced clamp means 46. Each clamp means 46 comprises, FIG- URE 7, a fixed block 47 rising from the adjacent end member 78, and overlying and abutting against the arm 116 is a bar 49 which has one end 48 supported in a slot 50 provided in the end member 78 and has the other end portion 51 bearing upon and secured to the block 47 by means of a bolt 52.

The torsion bar 112 underlies the torsion bar 119, and has its arm 114 extended into the related side member 27 of the upper bed frame member 26. The arm 116 of the torsion bar 112 extends along the adjacent end member 78 and is fixed upon the end member 78 of the anchor frame 74. As shown in FIGURES 4 and 5, in the use position of the bed 22, the arms of the

torsion bars

110 and 112 are in spaced parallel horizontal positions and the torsion bars are under maximum torsional stress; and in the storage position of the bed, the arms of the two torsion bars are at right angles to each other and the torsion bars are under minimum torsion stress. Since the intersection of the torsion bars is located inwardly of the axes of the hinges 88, the stressed condition of the torsion bars, in the storage position of the bed 22, serves to hold or counterbalance the bed 22, including the box spring 166 and the mattress 108, in erect position within the recess 12 and to overbalance the same slightly in an inward direction, so that the outer end 122 of the panel 38 is forcibly engaged with a transverse stop bar 124, which is suitably fixed to the underside of the top wall 20 of the recess 12, inwardly of the wall 10, so that the wall panel 38, secured to the underside of the bed frame 24, is disposed with its then outer surface 126 flush with the outer surface of the wall, as shown in FIGURE 5,, and closes the opening of the recess, in a manner to 4 constitute a practically indistinguishable part of the wall 15 Looking means is provided which is operatively connected to the anchor frame 74 and the head 44 of the bed assembly 22 and which is actuable upon execution of the movement of the bed assembly to the use position, said locking means serving to releasably hold the bed assembly 22 in fixed position upon the adjacent portion of the floor surface F. Specifically, this locking means comprises a pair of articulated rod members 55 which have their ends pivotally connected to the head 44 of the bed frame 24 and the anchor frame 74. Each of the ends of each rod member 55 is provided with a sleeve 56 adjustably connected to the adjacent end of the rod member with the free end of the sleeve 56 provided with a flattened stem 57 which permits pivotal connection to the adjacent head or anchor frame 74. An articulated arm 58 has one end pivotally connected to the joint 59 of each of the rod members 55 and has the other end pivotally connected to the anchor frame 74. It is to be noted that the part of the arm 58 having the end 60 is longer than the part of the arm 58 having the end 61, and disposed transversely of the first-named part and fixedly secured in a block 62 serving as a stop, the block being located adjacent to and below the joint 63 of the arm 58. This stop or block serves to retain the arm 58 in the extended position, but permits the two parts of the arm 56 to pivot about the joint 63 in a direction away from the head 44. Spring means in the form of a coil spring 9t; is operatively connected to each of the arms 53 and the head 44 of the bed frame 24 for retaining the arm 58 in its extended position.

The head or headboard 44 is provided with floorlevelling means for adjusting the bed when in the storage position to the level of the floor portion 14 of the floor to thereby permit the panel 38 to snugly fit the recess 12. This means comprises a U-shaped member 91 located on the under face of the head 44 inwardly of and adjacent each end and having the legs fixedly secured to the head with the bight parallel to the head, and a floor-engaging element 92 threadedly supported in the bight.

The bed assembly 22 is also provided with a releasing means which is operatively connected to the anchor frame and the locking means and which is operable at the will of the user of the bed assembly to shift the locking means out of the position releasably holding the bed assembly in the fixed position upon the floor F. Such means comprises a pair of bars 93 arranged in confronting end-to-end spaced relation, and a connecting member 94 interposed between and pivotally connected to the confronting end of the bars 93, the connecting member 94 being connected to a cable 95, Whose free end extends through the footboard 64 and may be grasped by the user of the bed assembly to actuate the releasing means. Spring means in the form of a coil spring 96 is operatively connected to the connecting member 94 and the anchor frame 74, the spring 96 serving to urge the connecting member 94 away from the head 44. A flexible member or chain 97 connects the non-confronting end of each bar 93 to the joint 63 of the adjacent articulated arm 58.

The box spring 106 and mattress 108 are provided with cooperating releasable attaching means which extend along each of the 'complemental sides of the spring and mattress and which is of a construction such as to permit tucking of a sheet between the complemental side edges of the box spring and mattress when the cooperating means are in attaching relation and the bed assembly is in use position. This cooperating means comprises a flexible tab which extends along and inwardly of and spaced from each of the sides of the box spring and which has one side edge secured to the top of the box spring and which has a plurality of male fasteners 136 extending in spaced relation along the opposite side edges of the tab 135. Extending in spaced relation along each of the sides of the mattress are a plurality of female fasteners 137. The thus described cooperating attaching means permits repositioning or replacement of the mattress when the cooperating means are in detached relation and the bed assembly is in use position.

In operation, the bed 22 being in storage position in the recess 12, the bed is manually started out of the recess, a ratch (not shown) or other suitable finger-hold means being provided for the purpose on an edge of the panel, until the Weight of the bed 22 overcomes the stress of the torsion bar assembly .104, whereat the weight of the bed takes over and lets the bed 22 swing slowly and gently down to a use position upon the room floor F. This action can be restrained or accelerated by grasping the footboard handle 72. As soon as the bed 22, has execnted its movement to the use position the locking means acts to releasably hold the bed in fixed position upon the adjacent portion of the floor F, and to retain it in such position until the user is desirous of restoring it to the storage position.

For moving the bed 22 from use position to storage position in the recess 12, the free end of the cable 95 is grasped and pulled outwardly, resulting in the shifting of the locking means out of the position releasably holding the bed in fixed position. The handles 72 are then grasped and the bed started upwardly by a gentle upward pull thereon, to a point whereat the panel 38 can be pushed toward the recess 12 until the counter-balance assembly 104 and the weight of the bed take over and close the panel into place in the recess, the action being such that risk of slamming the panel into place is minimal.

The bed spring 106 is preferably lightly secured to the bed frame 24, as by means of straps 128 secured, as indicated at 130 and 132, to the outer sides of the bed spring 106 and side members of the [upper bed frame member 26.
