111., a corporationof Delaware 6 Claims. The present invention relates k to improvements in twin studio couches or davenports, and

hasparticular reference to anew and improved couch having two relatively movable sections adaptedto' be' positioned in angular relation for use as a seat and back rest respectively or a lounge, and to be moved into relatively projected position with" both units horizontal to provide a doublesleeping surface.

One of the objects of the invention is to provide a couch of the foregoing character in, which both of the couch sections are disposed at bed height when arranged as sl-eeping surfacesp A further object is to provide a twin section couch or the foregoing character in which one of the couch 'sections is provided in the form of a swinging back connected to a stationary base structure by a linkage mechanism which serves to lock the swinging couch section firmly, though releasably, in either upright or horizontal position.

A further object is to provide a twin section couch of the foregoing character in which the couch sections can be operatively disconnectedfrom each other only when the sections are in extended horizontal sleeping surface position. so that the sections may be separated for independent usc. v

A general object of the invention is to provid a novel twin section couch having a supporting" mechanism for swingably supporting one of the sections in either a back restpcsition orsleeping surfaceposition, which is simple and inexpen-- sive in. construction, which is easy to operate, and which is substantially concealed from view when the sections are in assembled relation:

Further objects and advantages of theinvention' will become apparent as the following description proceeds, taken in connection with i l the accompanying drawings inwhich:

While the invention is susceptible mam.

modifications and alternative constructions, a preferred embodiment has been shown in the drawings andis herein described in detail, but, it is to be understood that there is no intention to thereby limit the invention to thespecific form disclosed, but on the other hand, the intention is to cover all. modifications andalternative constructions falling within the spirit and scope of the invention by the appended claims.

Referring more particularlyto the drawings, the couch illustrated (Figs. 1 and 4) comprises two relatively movable couch sections 1 and 2 adapted to be disposed in angular relation to form, respectively, a backrest and seat of a lounge (Fig. 4), or to be adjusted into separated or relatively projected position and horizontal position (Fig.5) for use as twin sleeping surfaces or beds. The back rest section Iis swin'gably mounted, by a novel mechanism hereinafter described, on a stationary base unit 3 which rests on the fioor. This base unit comprises a rec- Toc'on'di'tion' the couch for sleeping purposes the couch-sectiont is pulled rectilinearly forward away from the base unit 3. This couch, section 2 comprises a border frame 8 open at the rear to receive the stationary base unit 3, and more particularly comprising a longitudinal front channel member 9 (Figs, 5and 9) and end channel members iii. A rear longitudinal angle bar I l spansandis secured to the top of the rear ends of the frame members i ll. members 9 and iii has upper andlower flanges l2 and I3 extending'inwardly in vertically spaced relation.

The section 2' is supported by four corner legs i i (Fig. 5) which are'secured to the lower flanges l3 cf'the endImembers lllgancl whichare providedwith' casters l5 adapted'to roll onjthe floor. Aprons'lfiflalscsecureti to the" lower flanges 13 Each of the frame of the frame, serve to conceal the legs I4 substantially from View.

Mounted on the top of the border frame 8 is a box spring structure I! (Figs. 4 and 5). A cush ion I8 may be removably or fixedly positioned on the spring structure [1 to provide a seating surface or a sleeping surface of suitable height from the floor.

The other, or swingably mounted, couch section I has been shown herein (Figs. 1 and 4) as embodying a rectangular border frame I9 made of longitudinal and transverse angle bars and 2!, respectively. On this frame is stretched what is commonly known as a flat springstructure 22. An upholstered cushion 23, similar to the cushion i3, is removably positioned in front of the frame I 9 when the couch is contracted for use as a lounge (Fig. 4). This cushion 23rests on the rear portion of the base unit frame 45 and is pressed against the front face of the upright frame 19 by the box spring structure I! on the horizontally slidable couch section 2. The parts are so dimensioned that when the couch section 2 is in its retracted or nested position over the stationary base 3 a channel or space will be left at the rear of the couch section 2 to receive the lower edge of the cushion 23. On the other hand, when the frame I9 is positioned horizontally (Fig. 5) for sleeping purposes, the cushion 23 is laid on the top side of the frame I9 soas to form a suitable sleeping surface thereon. The cushions l8 and 23 may, if desired, be made interchangeable,

In order to support the frame I9 for swinging movement on the base unit 3, a linkage is provided such that when the frame I 9 is in horizontal position the upper surface of the cushion 23 on it will be substantially flush with the top of the cushion I8. In this way two sleeping surfaces, on the cushions I8 and 23, are provided, and both are at bed height. This is to be distinguished from various prior studio couch constructions in which a plurality of sleeping surfaces are provided but all at a comparatively low height from the floor. The couch unit of the present construction provides what are known as bed highisleeping surfaces.

The particular linkage shown herein for; sup.- porting the frame I9 embodies a pair of crossed links 24 and 25 (Figs. '1, 4 and 5) at one end of the couch. "A similar linkage is provided at the opposite end; but sin ce the two are substantially identical a' description of one will sufiice for both. The link 25 is somewhat shorter than the link 25 and is of an elongated S-shape, being pivoted to. the rear portions of the frame I9 and base unit frame at 26 and-27, respectively. The other link 25 is somewhat curved (see Fig, 5) and is fashioned with offset ends (see Fig. 1) which are pivoted, respectively, to the frame I9 at29, and at 29 to a bracket 30 which is fixed to the end channel 5 on the frame of the base unit 3. The pivot 29 is located inwardly of the pivot 25 on the frame I9. With the links 24 and 25 fashioned and pivoted" as shown, the link 25 swings across the link 24, when moving from the position of Fig. 4 to that of Fig. 5, and finally engages the stop pin 3I fixed on the link 24. In this way the links 24-25 and the frame I9 are locked against further forward movement when the frame I9 reaches its horizontal position.

lit

For "supporting the front of the frame I9 at r the desired height when the frame is horizontal retractable legs 33 are utilized (Figs. 4 and 5)..

at 34 and are interconnected with the linkage supporting the rear of the frame I9 in such manner that the legs are retracted to a horizontal position when the frame I9 is upright, and are projected into a vertical position when the frame I9 is horizontal. In particular, a link 3-5 is pivotally connected to the lower portions of the leg 33 at a point eccentric with respect to the pivotal connection of the leg to the base frame. The other end of the link 35 has a lost motion connection with the link 25 by means of a pin 35 on the link 25 and a slot 31 in the link 35. Consequently, when the link 25 is swung clockwise (as viewed in Fig. 4) the link 35 is pivoted generally endwise to the right and pulls the leg 33 down to a horizontal position. The legs 33 are; made of angle iron so that when in this hori-- zontal position they fit snugly about the top of." the frame of the base unit and out of the way; of the horizontally slidable couch section 2. Sim-v ilarly, when the link 25 is shifted in the opposite-.- direction, to the position shown in Fig. 5, the link; 35 is thrust generally endwise to the left and; turns the leg 33 to its upright position so that. the descending frame I9 rests firmly on its fiat. upper end.

To further aid in looking the links 24 and; 25 while the frame I9 is in horizontal position}. a latch frame, designated generally by the numeral 38 (Figs. 2 and 3), is pivoted on the links.- 24 by the stop pins 3i. The frame 38 is made up by a pair of angle bars 39 pivoted on the inner; ends of the pins 3|, and a longitudinal reenforc ing bar 49. The lengths of the frame, end bars; 39 are so dimensioned with respect to a, pair of upstanding stop pins 44, on the. Stationary base unit frame channels 5, as to lodge against the forward faces of these pins, when the links 2 19 and 25 are swung forwardly to the position of Fig. 5. With the ends, 015. the latch frame bars 39 wedged against the pins. 44., as shown in Fig. 5, the links 24 are held against clockwise movement. a was pre io s y no ed, the links 25 are ld g st m vem nt in the opposite or coun- B rock ise movement by their abutment or stop pin 3i. AS a result the cross links 24 and and then swing, it upward a short distance so as.

to clear these pins.

A suitable interconnection is provided between; the horizontal sliding couch section 2 and the.- stationary base unit 3 in order to guide the former and releasably secure it against separation. from the base unit 3. In general, the mechanism: is the same as that embodied in the twin studio; couch disclosed in copending'application Serial No. 220,632 of Ira M. Pink and Victor Bergstrom, filed July 22, 1938. 9

As shown in Fig. 9, this mechanismembodies; a pair of links 45, each of which has its forward end pivoted on a corresponding bracket 46 fixed to an end channel It) of the sliding couch unit 2. The other end of each of the links is connected by a pin 47 to the front channel member 4 of the stationary base unit 3. The pins 47 (Figs. 6, 7 and 8) are rigidly fixed to the corresponding links 45 and extend downwardly through elongated slots! in the upper forward- 1y projecting flanges of angle brackets 49 riveted to the front of the frame member 4. The lower ends of the pins 4'! are flattened to provide flared keys 50, which are rotatable as an incident to the swinging of the links 45 into locking relation with the slot 48. Except when the couch section 2 is substantially in full projected position, the pins 4'! are not readily accessible and the locking keys 59 are not in parallel alinement with the slots 48, and, hence, prevent separation of the levers @5 from the brackets 49. The slots &8 permit relative shifting of the pins 41 to accommodate the arcuate movements of the latter as the levers are swung from either extreme position to the other. When the couch section 2 is in its fully projected position, the keys 5!] register with the slot 43 so that they may be lifted upwardly through the same and the couch section 2 completely detached from the stationary base unit 3, with the result that the couch section 2 can be positioned independently anywhere in the room, as desired.

The two links 45 at the opposite ends of the couch (Fig. 9) are interconnected by equalizing means to insure straight line movement of the couch section 2 as it is moved into and out of nested relation with the base 3. This means consists of two cross bars 5|, secured respectively to the links 45 adjacent the brackets 43, and cross cables 52 connecting the ends of each bar respectively to the reverse ends of the other bar. Inadvertent forward sliding of the couch section 2 is prevented by a releasable latch connection between it and the stationary base unit 3. This latch connection has been shown herein (Figs. 1, 4 and 5) as including a stop member 53 fixed on a cross brace 54 of sliding couch unit frame 6, and projecting downwardly and forwardly therefrom. A cooperating latch 55 is pivoted on the stationary frame member 4 at 56, and is fashioned with a forwardly projecting operating extension 51. When in upright position (Fig. 4) the latch 55 lies in the path of the stop member 53 and engages it soas to prevent forward displacement of the couch section 2 relative to the base unit 3. The operatorhas but to kick the latch 55 to one side or the other, however, in order to free the stop member 53 so that the couch section 2 can be slid forwardly. In the use of the couch described above, the couch sections I and 2 are positioned as shown in Figs. 1 and 4 when the couch is to be used as a lounge or seat. To make up the couch into twin beds the latch 55 is swung out of the way of the stop member 53 and couch section 2 pulled forward away from the stationary base unit 3 so as to expose the top of the latter. In the extreme forward position of the couch section 2 the keys 5!! are in registry with their corresponding bracket slots 48 so that they can be pulled free from the same and the couch section 2 moved about the room to any position desired.

After having exposed the upper surface of the base unit 3 by pulling out the telescoped couch section 2, as described above, the couch section l is swung into the horizontal position of Fig. 5. To accomplish this it is simply necessary to remove the cushion 23, grasp the frame l9, and swing the latter forwardly and downwardly. During this forward swinging movement of the frame IS the legs 33 are automatically projected into upright position by their associated links 35. Finally, the latch frame 38 is wedged against the forward faces of the stop pins 43. In this way the frame I9 is rigidly fixed in horizontal position above the stationary base unit 3. The cushion 23 is then placed on top of the frame it and a second sleeping surface is thus provided at bed height fromthe floor.

To reassemble the couch into its contracted position (Fig. 4) for use as a seat or lounge, the cushion 23 is removed and the latch frame 38 (Fig. 5) pulled forwardly and upwardly to release it from the pins 44. Then the frame I9 is swung to its upright position and in the course of such movement the legs 33 are automatically retracted. This return swinging movement of the frame I9 is limited by the engagement of the pins 35 with the outer ends of the slots 31 in the links 35 (Fig. 4), and also by the engagement of the rear bar 20 of the frame I9 with the back of the base unit 3. If the couch section 2 has been previously completely disengaged from the base unit 3, it is rolled back to position at the front of the base unit and the keys 5!! thrust into the slots 48. Thereafter the couch unit 2 is pushed toward the base unit 3 so as to telescope it over the latter and in this return movement the links 45 and equalizer cables 52 guide the couch section 2 for straight line movement. The cushion 23 is replaced in front of the upright frame l9 (Fig. 4) and the couch section 2 pushed to its fully retracted position and in which position it is latched by the latch 55. In that way the couch is quickly and easily assembled in the form of an attractive lounge or studiocouch.
