For purposes of disclosure, I have illustrated in the drawings and shall hereinafter describe in 5g detail a preferred form of the invention,` together with a modified. form thereof, with the understanding that I do not intend to limit the invention to the particular constructions and arrangements shown, it being contemplated that various changes may besmade'by those skilled in the art 5 without departing'from the. spirit and scope of theappend'e'd claims. y

`Asaillustrated in Figs. 1 to 4, the invention is ini the lform of a. davenport which-is convertible into beds. This davenport comprises upl right end frames I0 and I I' lsecured in laterally spaced relation by a rearbase board I2 and a bottom board I3. The end frames have vertical front members Il. and vertical rear members'` Il, horizontal top members I6 and horizontal base boards I1, al1 secured together by glue or other means to form rectangular frames. These are generally covered with padding and cloth as indicated by dotted lines I3 in Fig. l. Feet Il extend downwardly from the rear ends of the endl t. frames, and feet I9' are secured to and support the front ends thereof. An intermediate frame'l 20 in the form of a board extends forwardly from the rear base board I2 and upwardly from the bottom board I3 and is preferably glued to both. u

Movably supported and adjustable on the frame structure just described are pairs of seat frames 2|, back frames 22and holding frames 23, all of which are upholstered and covered 'as indicated by the dotted outlines 2|', 22' and 23'. respectively. Each seat frame 22 isiconnected to a back frame 2| by means of a pair of automatic hinges 24 and 25 of well known construction, and each folding frame 23 is secured to the front edge of a seat frame 22 means of a.v plurality of 35 hinges 26 with thefresult that each set of connected frames may :be adjusted independently from the positions shown in Fig. 1 (wherein they form a davenport) to thepositions shown in Figs.

3v and 4 (wherein they form twin beds). 40 y Each automaticihinge comprises metal brackets 3|I"and 3|, secured as by means of screws to the end portions of the seat frame 2|, and back frame 22. These brackets are pivotally connected together by headed pins 32 to form a hinge joint. 45 Links 33 and 34 have their lower ends pivotally secured to a metal bracket 35 by headed pivot pins 36 and 31, respectively, and have their upper ends secured respectively to the headed pin 32 and a headed pivot pin 38 on the bracket 3|. These 50 links serve as a, supporting means for the seat frame 2| and back frame 22, the brackets 35 being mounted one on each end frame base board I'I `and two on the intermediate frame board 2l. The hinged brackets 30 and 3i of each automatic l hinge are normally secured in the relative positions shown in Fig. 1 by means of a hook member 39, pivoted on the bracket 30 by a headed pin 40. The free end of the hook rides fiat against the bracket 3| and under a U-shaped staple 4| secured to said bracket. The free end of the hook member 39 has a notch 42 therein arranged to receive one leg 4| of the staple and thereby hold the back frames 22 in the upwardly inclined position shown in Fig. 1. A suitable spring 43 is cai'- ried on the bracket 30 and serves to pivot the hook 39 in a clockwise direction, as shown in Fig. 1, to insure engagement of the notched end of the hook with the staple leg 4|'. A pin 44 extending from the stationary bracket 35 limits the clockwise movement of the link 33, as shown in Fig. 1. and enables the links to determine the positions of the seat and back frames.

A cam member 45 is pivoted on each hook 39 on a pin 46 and is arranged to pivot from the position shown in Figs. 1 and 2 to the position shown in Fig. 3 for the purpose of disengaging the hook 39 and permitting the seat and back frames to be straightened out. Since the automatic hinges are in themselves old and well known, it will suilice to say that the hinges 24 and 25 are duplicates with the exception that one is lefthand and the other right-hand, and there is one pair of hinges for each seat frame.

The front end of the seat frames are herein shown in Figs. 1 to 4 as supported by legs 55 which have horizontal portions at their upper ends secured to the seat frame by screws 5|. The lower ends of the legs 50 extend downwardly to rest on the floor indicated at 52 at a point rearwardly of the legs i9' when the frames are in the positions illustrated in Fig. 1. The front ends (when extended) of the folding frames 23 are provided with a plurality of legs 53, the lower ends of which carry casters 54 which rest upon the door. Preferably, a strap handle 55 is secured to the upholstered portion 23' of the folding frame to facilitate handling.

When the invention of Figs. 1 to 4 is in use as a davenport, the parts are in the positions shown in Fig. 1. To convert the davenport into twin beds, a handle 55 is grasped and the corresponding folding frame 23 is pulled forwardly and upwardly throughthe position shown in Fig. 2 to a position in which the folding frame is swung outwardly from the bottom board.|3 and the back frame 22 is substantially horizontal. A slight additional clockwise movement of the seat frame 2| then permits the cam members 45 of the automatic hinges to move partly over the notches 42 of the hooks 39 so that upon a reverse or counterclockwise movement of the seat frame 2|, the hooks 39 slip out of engagement with the staple leg 4|' and the seat and folding frames can assume the positions shown in Fig. 3, wherein they are stretched out to form a bed. Due to the movement of the links 33 and 34, the legs 50 are now positioned forwardly of the legs I9'. By repeating these operations on the other set of frames, the other twin bed may be obtained.

To change back to anavenport, the handle 55 of one folding frame is grasped and pulled upwardly until the hooks 39 of the automatic hinges are engaged, and the folding frame 23 is then swung back under the seat frame before the s eat frame is lowered into position. The lowering of the seat frame to its horizontal position raises the back frame to the position of Fig. 1. This operation is then repeated on frames.

the other set nf In the form illustrated in Fig. 5, t'ne invention is shown as having end frames I and connected by a rear base board I2 and a bottom board I3. A single set of adjustable frames are provided comprising a seat frame 2|, a back frame 22 and a folding frame 23. The seat frame 2| and back frame 22 are connected together and supported on the end frames by hinges 24 and 25 and hinges 26 connect the folding frame to the front edge of the seat frame. The principal difference between the form of the invention illustrated in Fig. and the form of Figs. 1 to 4 is in the provision of a single set of folding frames 2|, 22 and 23 instead of two sets. By making the base frame and folding frames relatively long, as shown in Fig. 5, the invention serves, alternatively, as a davenport and as a double bed. By making the frames somewhat shorter, this form of the invention would be convertible from a chair toa twin sized bed or day-bed. Under these conditions, the invention is also convertible into a combination chair and ottoman, the folding frame 23 forming an extension to the seat frame and serving as an ottoman.

In Figs. 6 to 9, the invention is embodied in a chair which is convertible from the chair form, shown in Figs. 6 and 7, to a combination chairottoman form, as shown in Fig. 8, and, alternatively, is convertible into a bed. as shown in Fig. 9. Since certain of the frame parts in these figures are shown covered or as having upholstered cushions thereon, a brief description thereof follows.

Generally, the chair comprises upright end -frames ||0 and connected in laterally spaced relation by a rear base board ||2 and a bottom board ||3. Feet H9 extend downwardly from the rear ends of the end frames, and feet I I9 are secured to and support the front ends thereof. Movably supported and adjustable on the frame structure just described is a seat |2I, a back |22, and a folding cushion |23, including, respectively, a seat frame |2I, a back frame |22', and a folding frame |23. 'The seat frame is connected to the back frame by means of a pair of automatic hinges identical with those illustrated and described in connection with Figs. 1 to 4, so that the hinge visible in Fig. '7 bears the numeral 25 and parts thereof bear the'same numbers as corresponding parts in Figs. 1 to 4 inclusive. For purposes of clearness, certain of the parts have not been illustrated in Figs. 7 to 9. These hinges function in the manner hereinbefore described to support the seat and back frames either in the relative positions shown in Figs. 'I and 8 or, alternatively, in the relative positions shown in Fig. 9.

The front end of the seat frame is shown in Figs. 6 to 9 as supported by legs 50, and the folding frame |23' is secured to the front edge of the seat frame |2I by means of a plurality of hinges 26. The lower ends of the legs 50 extend downwardly to rest on the floor indicated at 52 at a point rearwardly of the legs l I9 when the frames are in the positions illustrated in Figs. 6, 'l and 8. The front end of the folding frame |23 is provided with a plurality of legs 53, the lower ends of which carry casters 54 which rest on the floor when the parts are in the positions shown in Figs'. 8 and 9. These legs'53 extend upwardly behind the back frame |22' when the parts form a chair, as shown in Fig. '7. A strap handle 55 is preferably secured to'the folding cushion |23 to facilitate changing the chair into an ottoman-chair or bed, or vice versa.

When the invention in the form illustrated in Figs. 6 to 9 is in use as a chair, as shown in Figs.

v6 and 7, it may readily be converted into the chair-ottoman combination of Fig. 8 by grasping the handle 55 and pulling forwardly and upwardly thereon until the folding cushion I2! swings out of the space under the seat cushion I 2i, so that it may be straightened out to the position shown in Fig. 8. While the folding cushion is being pulled out, care is taken so as not to operate the automatic hinges 24, 25, thus leaving the back cushion |22 in the position shown in Fig. 8. To change into the bed illustrated in Fig. 9, the seat cushion is swung upwardly in a clockwise direction, as viewed in Fig. 8, until the automatic hinges are operated, in the manner hereinbefore described, to release the hooks 39 and thereby permit the frames to assume positions shown in Fig. 9.

In either form of the invention, when converted into a bed, the joints between the folding frames run crosswise of the bed and are, therefore, much less noticeable toa sleeper than if they ran lengthwise of the bed.

I claim as my invention:

1. A chair comprising a pair of end frames,

means for supporting said frames in laterally spacedv upright position, a seat cushion, a back cushion, hinge devices including a releasable latch normally connecting said seat cushion and said back cushion in rigid relation but permitting the back cushion to be placed in a horizontal position upon release of said latch by lifting said seat cushion to a predetermined position, and returning said seat cushion in alignment with said back cushion, means connecting said hinge devices to said end frames, `,a folding cushion pivotally connected to the forward end of said seat cushion and normally underneath said seat cushion and .movable in alignment therewith upon raising of said seat cushion to a height short of the position for actuation of said latches, and means for supporting said folding cushion when in aligned position to provide a chaise lounge, the chair seat, the chaise lounge and the bed being each of the same height when respectively converted thereto for such use.

2. A chair comprising a pair of end frames, means for supporting said frames in laterally spaced upright position, a seat cushion, a back cushion, hinge devices connecting said seat cushion and said back cushion, said hinge devices being operative to normally -hold said seat cushion and said back cushion in rigid relation, said hinge devices being further operative upon lifting said seat cushion to a predetermined position to permit said back cushion to be placed in a horizontal position and said seat cushion to be returned in alignment therewith, means connecting said hinge devices to said end frames, a folding cushion pivotally connected to the forward end of said seat cushion and normally underneath said seat cushion and movable in alignment therewith upon raising of said seat cushion to a height short of the predetermined position for actuation of said hinge devices, and means for supporting said folding cushion when in aligned position to provide a chaise lounge, the chair seat, the chaise lounge and the bed being each of the same.
