8 Claims.

This invention relates to studio or convertible bed couches of that kind in which the couch back is adapted to be shifted to lie alongside of the couch seat and together therewith form a full width bed.

The objects of the invention are to provide a desirable, practical and easily operable convertible bed couch of novel construction; to provide a convertible bed couch in which the supporting frames of the couch seat and back are relatively movable laterally for converting from couch to bed and vice versa, and the back is moved from its normal standing position to a horizontal position beside the couch seat to form the bed; 15 in which, in converting from couch to bed, the

' couch seat moves forwardly and the couch back moves downwardly and. forwardly to a horizontal position beside the seat without either the seat or the back being inverted, so that the same surfaces which form the top of the seat and the front of the back form the top surface of the bed; which is of simple and economical construction; which is adapted to be constructed and assembled with the minimum of labor and expense; in which the couch is easily converted into the bed by pressing downwardly and rearwardly on the upper edge of the back; in which the parts are firmly held in their bed-forming position without the necessity for latching or look- 30 ing means; in which when the back is moved upwardly and rearwardly to convert from bed to couch, the back is automatically latched or secured in its standing position; and which has the other features of improvement and advantage hereinafter described and set forth in the claims.

In the accompanying drawings:

The couch comprises a seat-supporting frame and a back-supporting frame, one of which is horizontally movable laterally relatively to the other for converting from couch to bed and vice versa. Preferably the back-supporting frame remains stationary while the seat-supporting frame is movable sidewise forwardly and rearwardly relatively thereto, and the former will be hereinafter termed the stationary frame, although the seat-supporting frame could be the stationary frame and the back-supporting frame the movable frame.

A metal seat-supporting frame is shown comprising upright angle bar legs l2 at its four corners, rigidly connected at their upper ends by horizontal front and rear angle bars l3 and M respectively and horizontal end bars l5. The horizontal bars [3, l4 and 15 form the base of the couch seat, which may be an upholstered spring seat consisting, for example, of coil springs supported by the base frame and forming a spring support for an upholstered seat pad or cushions Hi. This invention, however, is not concerned with the spring or upholstered construction of the couch, and the couch. seat and back, which are shown as of similar upholstered construe-- tion, may be of any usual or suitable form and construction, such as indicated by broken lines. At opposite ends of the seat frame are upright couch ends or arm members I! which may be con-' structed and rigidly fastened to the ends of the seat frame in any suitable manner. Thecouoh ends shown consist of upright, rectangular skeleton frames l8 covered by suitable covering fabric or material I 9. The seat frame is preferably furnished with supporting rollers or casters at the lower ends of its corner legs to facilitate rolling motion of the seat frame on the floor.

The back-supporting or stationary frame 2|, as shown, is also of metal construction and consists of upright angle bar legs 22 at its four corners rigidly connected by horizontal front and rear angle bars 23 and end bars 24 secured to the lower end portions of the legs. The end bars 24 shown have the ends of their horizontal flanges depressed and secured under the bottom ends of the legs, thus forming broad feet for the stationary frame. A horizontal end rail 25 is rigidly secured to and connects the upper ends of the corner legs at one end of the frame, and a similar end rail 25 connects the upper ends of the legs at the opposite end of the frame. Each of these rails 25 preferably consists of a metal channel bar arranged with its flanges extending inwardly, see Fig. 10, and its bottom fiange having an upturned or vertical, inner edge 26, the end rails thus forming guideways or tracks for supporting rollers for the couch back, as hereinafter explained.

The stationary frame is shorter and lower than the seat frame, which is adapted to stand over the former with its legs straddling the stationary frame and spaced outwardly beyond the ends of the latter, most clearly shown in Fig. 3, so that the seat frame is adapted to move forwardly and rearwardly from and to its normal position in which the couch seat overlies the stationary frame. As shown, the couch back comprises a rectangular metal frame formed by rigidly connected end bars 21 and longitudinal front and rear, or bottom and

top bars

28 and 29, and an upholstered spring back cushion, similar to the upholstered couch seat, supported by said back frame.

At its lower or front portion, and spaced inwardly from its ends, the back frame is equipped with rollers 30 arranged in and adapted to roll on the bottom flanges of the channel rails 25 of the stationary frame. As shown, these rollers are mounted on the ends of a longitudinal rod or axle 3| extending through bearing holes in brackets 32 which are rigidly attached to fixed cross bars 33 of the back frame and project downwardly from the back frame.

The back frame is also provided at its opposite ends adjacent its lower or front portion with outwardly'projecting, fixed studs or pivots 34 which, as shown, are-fixed to brackets 35, rigidly attached to the back frame at its lower or front corners and projecting upwardly and inwardly therefrom. These studs extend into and are adapted to slide and turn in vertical guides 36 on the vertical couch ends H. The guides 36 may be formed by slots in bracket plates 31 rigidly'attached to the frames of the couch ends Heads on the studs prevent them from pulling out of the slots, but the slots have open, lower ends through which the studs can be engaged in and disengaged from the slots in assembling and dismantling the couch;

38 indicates two levers-each of which is pivoted at one end, as by a bolt 38a,.to one of the back cross bars 33 and is fulcrumed near its opposite end'to the stationary frame-2|, preferably by means of a horizontal rod 39 which extends longitudinally of the stationary frame adjacent its rear edge. The fulcrumrod 39 may extend through holes in the levers 38 and bear at its ends in holes in the channel rails 25 of the stationary frame and in bearing plates 40 fixed to said rails at their inner sides. A coil tension spring 4| is attached at one end to the lower or rear end of each lever 38 and is anchored at its other end to the stationary frame asyfor instance, to the adjacent lower end bar 24 of the frame- These springstend to pull the lower ends of the levers forwardly and swing the opposite ends thereof upwardly to the position shown in Figs. 1 and 4, in whi h the couch back is in its normal standing position. By pressing rearwardly on the upper edge of the back,the lower or front edge thereof Will move forwardly, the rollers 30 travelling on the channel rails 25, and by reason of the engagement of the studs 34 in the slots 36 in the couch ends, will shove the seat frame forwardly to the position shown in Fig. 6, until the cross bars 33 of the back frame strike and rest upon a horizontal rod or shaft 42 which extends longitudinally of the stationary frame from end to end thereof, near its rear edge so that the back will thus be firmly supported in a horizontal position by the rollers 30 at its front edge and the shaft 42 adjacent its rear edge. The back and seat will then lie alongside of each other in the same horizontal plane and form a wide bed. In thus moving the back downwardly to convert the couch into the bed, the springs 4| are stretched and act to assist in lifting the weight of the back in returning the back to its standingposition when converting the bed into thecouch. The upward, rear movement of the couch-back to its normal position pulls the seat frame back over the stationary frame by reason of theengagement of the studs 34 in their slots 36 in the couch ends.

Latch means are provided for releasably securing the back in its normal standing position, such means, as shown, comprising two hookedshaped latches 43 fixed to the shaft 42 and projecting forwardly therefrom so as to hook over the roller axle 3| for holding the lower edge of the back from forward movement. Each latch has a downwardly and rearwardly bevelled front end, and in rear of the hook has an upwardly and rearwardly inclined or curved cam face 45 arranged to be engaged by the axle 3| When the back is moved upwardly and rearwardly, the axle 3| will strike the bevelled ends of the latches and lift the same so that the axle will pass under the latch hooks and the axle will then strike the cam faces 45 and positively cam the latch hooks downwardly in front of the axle to secure the back in standing position.

Foroperating the latches to release the back, a latch-operating lever 46 is shown fixed to one end of the latch shaft 42 at the outer side of the adjacent end of the stationary frame. By depressing the rear end of this operating lever 46,. the latches will be lifted out of holding engagementwith the roller axle 3| and release the back.v .Stop pins 41 on the adjacent end rail 25 are engaged .by the lever 46 to limit the up and down movement of the latches and prevent possible movement of the latches out of operative relation to the axle 3|. The latches could be released by any other suitable means such, for

instance, as a trip rod 41, see Fig. 4, movably mounted on the back frame and having a handle in convenient reach for operation, and a finger or part 48 at its lower end adapted, when the back is in normal position, to project under the front end of one of the latches for lifting them out of engagement with the axle 3|.

The described construction of the couch is simple and economical and facilitates the manufacture and assembly of the parts. Before assembly, the seat frame and back frame are disconnected, which facilitates upholstering the seat and back. In assembling the seat and back, the rollers 30 on the back frame are passed into the channel rails 25 of the stationary frame through their open front ends, and the seat frame is placed in position with its legs stradtiling the stationary frame and the rear portion of the seat over the front portion of the stationary frame. The back is then rolled rearwardly on the channel rails until the studs 34 at the ends of the back are brought into vertical alinement with their guide slots 36 in the couch ends I1, and the seat frame is lifted and the guide slots engaged over the studs 34. The upper or forward ends of the levers 38 are then attached to the back frame by the bolts 38a which completes the assembly. To dismantle or disconnect the parts, it is only necessary to remove the bolts 38a and reverse the described assembling operation.

In the normal position of the parts, with the back in its standing or upright position, the backoperating levers 38, which are bent, pass in front of and under the latch shaft 42 and, by striking the latter, limit the rearward movement of the back, while the lower end of the back will be held from forward and rearward movement by engagement of the latches 43 with the roller axle 3|. The back is thus firmly held in its standing position and prevented from tipping or moving forwardly or rearwardly so long as the latches are in holding position. To convert the couch into the bed, the latches are released and the upper edge of the back pressed rearwardly and downwardly. This tends to swing the back on its pivotal connections with the levers 38 and causes the rollers to travel forwardly in the channel rails 25, and the upper ends of the levers 38 to move downwardly and forwardly. In this movement of the back, the stud and slot connections between the back and the couch ends l'I move the couch seat forwardly, and such movement of the parts is continued until the back lies horizontally in rear of and alongside the seat in the same horizontal plane, as before explained. The reversal of these movements reconverts the bed into the couch, and the springs 4i acting on the levers 38 assist in lifting the back and moving the seat frame rearwardly. The device is thus readily and easily converted from couch to bed and from bed to couch.

When the couch is opened to form the bed, as shown in Figs. 2 and 6, the seat and back sections can be disconnected for use as separate beds, simply by lifting the seat section to disengage the pivot studs 34 from their slot guides 36 on the couch ends I1.
