Referring now more particularly to the drawings, it will be understood that in the embodiment shown in Fig. l, the device is arranged to simulate a sofa having a back rest-21, arms 28 and 29, and a front closure panel 30, all of which are upholstered to match the seat cushions 3i. The back rest 21 is preferably formed of a plywood panel which is padded and then covered with any suitable upholstery material.

The back rest 21 (Fig. 12) is secured to the framework 21A and 21B, and the side arms 28 and 28 are secured to the framework 213 and to a sub-base member 210 by means of bolts or other suitable means. The front panel 30 is secured by bolts or other suitable means to the base member 89A (Figs. 5 and 11) and is reinforced by braces 30A (Figs. 5 and 11) which connect to the base reinforcing members 94. The side arms 28 and 29 are preferably formed as boxes which are open at the top, so that pillows, bed clothes, and the like may be stored therein. Suitable lids 28A and 29A which are also upholstered serve as closures for the openings in the hollow side arms 28 and 29.

When it is desired to use the device as a single bed, as shown in Fig. 2, the seat cushions 3| are first removed and the bed frames carrying the front closure panel 35, and other elements as hereinafter described, are moved forwardly as shown in Fig. '2, so that the full width of the mattress 32 is exposed. Suitable bed clothes 33 may be used to cover the mattress 32 with top sheet 33A and blanket 33B and the device is ready for single occupancy.

When it is desired to utilize the device as a double-deck bed, the device is adjusted to the position shown in Fig. 3. In this position it will be seen that the mattress 32 'is now elevated and becomes the mattress for the upper deck.

I will now describe the mechanical structures which make possible the several conversions illustrated in Figs. 2 and '3. Broadly speaking the device consists of a lower rectangular bed frame 34 which is adapted to carry a mattress 35 and an upper bed frame 36, which is adapted to carry the mattress 32.

The bed frame 36 (Fig. 3) is supported at either end by means of a pair of arms 31 and 38 (Figs. 3 and 5). The arms 3'! and 38 are pivoted at their center, as at 39, and at their respective ends are provided with rollers 40 (Fig. 4) The arms 31 and 38 are also connected to the bed frame 36 by means of pairs of arms 4| and 42, which are pivoted to the arms 31 and 38, as at 43, and to the bed frame 36 as at 44.

The bed frame 38 is rectangular in shape and is formed of stock having a substantially T shaped cross section (Fig. 4) This member may be formed by bending and rebending a continuous piece of stock to form the mattress supporting portion 45, and the mattress retainer 46, and the guide member 41, or it may be formed by welding together lengths of right angular stock to form the same elements. When the frame is formed by bending and rebending a single sheet of metal. I prefer to roll the edges (as shown in Fig. 4) to provide strength. By so doing, I am enabled to use a lighter gauge metal without sacrificing strength.

The mattress supporting element of each bed frame is perforated near the inner edge, as at 45A to accommodate springs 45B (Figs. 4 and 8), to which springs are secured flat steel straps 450, which are inner-woven as at 45D to form a further support for the mattress and obviates the necessity of using conventional box springs under the mattress. The guide member 41 is slotted, as at 48, to accommodate the roller axle 49, which also extends through suitable bores formed in the channel-like member secured to the upper ends of the arms 31 and 38. Thus, it will be seen that the rollers 40 carried at the upper end of each arm 3'! and 38 provide frictionless but movable supports for the upper bed frame 35. fhe travel of the rollers 40 is limited by the lengths of the slots 48 and the arms 4| and 42. This structure helps to prevent any weaving between the upper and lower bed frame.

The lower ends of the arms 31 and 38 are likewise provided with rollers 5| and 52 (Fig. 15). The roller 54 is adapted to engage the under side of the mattress support 53 of the lower bed frame member 34 and the roller 52 is adapted to contact the upper surface of the outwardly extending flange 54 of the guide member 55 of the bed frame 34 and serves as a track for the rollers 52. The guide member 55 is slotted, as at 58, to accommodate the roller axle 51, which slot limits the distance of travel of the rollers 5i and 52 as previously described with reference to slot 48. Thus, it will be seen that the arms 31 and 38 will function to raise and lower the bed frame 34 as a result of a corresponding movement of the upper bed frame 36.

The lower bed frame 34 (Fig. 5) is supported at either end by pairs of cross arms 58, 59, 60, and Bi, which pairs of cross arms are pivoted at their centers as at '62 and 53. The cross arms 59 and 60 are pivoted, as at 64 and 65, to the guide member 55 of the bed frame 34, and the upper ends of the arms 58 and BI are pivoted to the roller axles 51 and are arranged to travel therewith. The lower ends of the arms 58 and 5! are pivoted, as at 65 and 51, to the guide portion 68 of the member 69, which comprises part of the base of the device. The guide member 68 is slotted, as at Ill (Figs. 5 and 14), to accommodate the axles 10A of the rollers H and 72 carried at the lower ends of the arms 59 and 6!). The rollers TI and 12 are arranged to ride on outwardly extending track portions E 3 and 73A (Fig. 14) formed on the base member 69. A rocker arm I4 (Fig. 5) is pivoted at its upper end to a link 11, which in turn is pivoted at its upper end to the lower end of the arm 3i, as at 51, and the lower end of the rocker arm 14 is pivoted to a link 18, which in turn pivoted to the lower end of the cross arm 58 as at MA. This arrangement insures the synchro-v nous travel of the rollers l l and T2 at the ends of the arms '59 and 60, and the rollers carried at the ends of the arms 37' and 38. A rocker arm '14 is mounted at each end of a shaft 75, which pivots in either end in a bracket 16 mounted on the base member 69.

Extending through the shaft 15 (Fig. 11) and in alignment with the rocker arm I4 is a torsion bar 83, to the ends of which are pivotally secured the springs 84 and 85, which in turn are secured at their opposite ends to the base members 69A and 693. The torsion bar 83 and the springs 84 and 85 serve to counter-balance all of the moving parts employed in supporting the upper and lower bed frames, so that the bed frames may be moved upwardly and downwardly with a minimum of effort.

A locking bar 19 (Figs. 5 and 11) is pivoted to the cross arms 60 and 6|, as at 63, and is provided with a slot 80, which is adapted to engage the pivot 62 of the cross arms 58 and 59. When the slot 80 is engaged with the pivot 62, the pairs of arms 58, 59, 60, and 6| are locked against movement, which in turn secures the bed frames 34 and 36 against vertical movement. The locking bars I9- at either end of the structure are tied together by means of a bar 86 (Fig. 9). The locking bars I9 may be simultaneously lifted out of locking position by means of a lift strap 81 which connects to the tie bar 88 and extends upwardly behind the front panel 30. Although I have herein illustrated and described fully only one end of the bed frame support, control, and locking mechanisms, it will be understood that similar structures and arrangement are provided at both ends of the bed frames.

In order to support the pairs of cross arms 58, 59, 60, and 6| in a vertical plane, I provide braces 88, 89, and 90 (Figs. 9, 11, and 15). The brace 90 is rigidly secured, as at 92 (Fig. 15) to the movable arm 58 and is pivotally secured, as at 93 (Fig. 11), to a channel-shaped cross member 94 which extends between the base members 69A and 693. It will be understood that each pair of cross arms is provided with a similar brace. In order to further steady the upper bed frame and to prevent its longitudinal movement when in elevated position, I provide braces 9I which are pivoted, as at 9IA (Fig. 9) to the upper bed frame 32 and are supported on rollers, as at 9IB, which travel in slots SIC formed in the lower bed frame 34. The movement of the braces 9I is lim ited by the length of the slots 9IC. The rear portion of the base member 693 (Figs. 11 and 12) is supported on rollers 96 which travel on tubular members 91 which in turn are supported by the sub-base framework 98, 99, and I00. The

front portion of the base member 69A is supported on rollers 95, which in turn are supported by the floor. The forward movement of the base members 69A and 69B is limited by the stops 91A. When the base members 69A and 69B are moved to the rear, the rollers 96 rest in depressions 91B formed in the tubular members 91, so that the base member 69 may not accidentally be shifted forwardly.

When the device is used as a sofa the forward movement of the bed frames is guided by rollers IOI, which ride against the inside surfaces of the arm members 28 and 29. When the device is in folded position, as shown in Figs. '7 and 18, the bed frames rest on rigid stop members or spacers I02. This takes all of the strain off of the moving parts. The upper bed frame 36 (Fig. 3) is provided with a guard rail I03 which is pivoted, as at I04, and when not in use, is swung into the position shown by the dotted lines I03 and is nested in an out of sight position when the bed frames are in lowered position. A hand grip I05 is provided on the upper bed frame 36, so that the device may be easily manipulated.

In Fig. 16 I illustrate the use of the device as a day bed. In this embodiment the frames are removed from the framework 21A and 21B and the sub-base members 91, 98, 99, and I00. This is accomplished by simply lifting the back rollers 96 from their tracks 91 (Fig. 11).

When using the device as shown in Fig. 16, I employ a drapery or skirt I06 to conceal the working parts. The skirt is secured to the base 69 (Fig. 19) by means of corner brackets I01, which brackets support a rod I08, which encircles the lower bed frame. The rod I08 (Figs. 20 and 21) is provided with a threaded coupling I 09, so that the skirt I06 may readily be assembled or detached. In Fig. 17 I illustrate the manner in which the day bed may be converted into a double-deck bed as previously described.

In Fig. 22 I illustrate the manner in which the device may be employed as a Hollywood bed by attaching bed legs IIIA to the base member 69 and to the headboard H0. The legs III of the head board IIO are secured to triangular shaped brackets II 2 (Figs. 22 and 23) which are preferably welded to the base members 69. Rest plates II3 are welded to the bottom of the base members 69 and are adapted to support L shaped brackets I I4 which are attached thereto by means of wing nuts and bolts H5. The members III and H2 and H4 are then secured together by means of nuts and bolts H6. Rubber stops III are secured to brackets I I4 by means of nuts and bolts H8. The rubber stops I" prevent the bed or its headboard from marring the walls when being moved.

From the foregoing it will be seen that I have devised a piece of furniture which has great utility and which may readily be converted into either a sofa, single bed, day bed, double-deck bed, or a Hollywood bed.

Having described my invention what I claim and desire to secure by Letters Patent is:
