and hasfor its principal object to produce a foldable" st ucture which is simple and inexpensive, yet strong and durable, which may be readily opened as a full size bed and folded compactly into a small space to constitute a sofa or divan.

It further object is to produce a structure wherein the pivotal frame sections are Well balanced so that the Weightand leverage are equalized throughout the opening and closing movements thereof.

()ther advantages hereinafter more fully appear.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

in the accompanying drawings which form part of this specification and wherein like svmbols refer to like parts Whereverthey occur,-Figure 1 is a side elevation of the device folded as a sofa or divan; Fig. is a side elevation showing the device par tially opened; and Fig. 3 is a side elevation of the device fullyopened as a bedstead.

The device comprises a supporting frame comprising vertical front and rear corner members 1 and 2, respectively. The lower portions of the members 1 and 2 are connected by said members 1 and 2 are respectively connected to the member 3 by diagonal braces 1 and 5. The vertical members 1 and 2 are respectively connected near their lower ends by front and rear cross members 6' and 7 3 and, obviously, diagonal braces or stays 5 similar to those t and 5 above noted, may connect said members 2 with their cross member 7. The rear vertical corner members 2 are extended up as at 2 near their upper ends by a cross member 8. The extensions 2 and cross members 8 serve as a head-board and also a support for the folding outer frame section (hereinafter described) when it is in closed position.

Pivotally supported on the front vertical corner members 1 is a reversible frame comhorizontal end members 3: and

and connected prising triangular end members 9, 10 and 11. The members 1.0 and 11 are res ectively connected by cross members 12 an 13 and they may be suitably. braced by diagonal stays12 and 13 similar to thosed and 5 above set forth. The

versible frame are pivoted, as at 14310 brackets 14 secured to the front vertical of the members 11. The end portions 10 pivotal frame members 10 are extended some distance beyond the members 9 and are pivotally connected, as at 15, to extensions 15 of end members 15 of a cooperati'n frame Whose other end members 16 and 1% are connected to said members 15 in triangular relation. Across member 18 connects the res ective end frame members at or about t e juncture of the members 15 and by diagonal stays 18 bers 16 are extended some distance beyond the point of juncture with the members 17 and are pivotally connected to the upper end portions of supporting links 19, as at 19*. The links 19 are pivotally connected at their lower e1 1 v as at 19, on brackets 20 secured on the lori'zontal end members 3 of the supporting frame. The members 9 of the reversible frame have their end portions 9 extended some distance beyond the point of juncture with. the members 11 members 10 of the re 17 and is also connected to the members 1-5 I '75 The rear end portions 16 of the mem-' iind pivotally connected to extensions 21of end members 21 of a second cotiperating folding frame, as at 21. The opposite end portions of the members 21 are secured to members 22 constituting supporting legs for the frame in its open position, as shown in Fig. The legs 22 and frame members 21. are connected by diagonal stays 23; and said legs 22 are also connected by across member 24. The cross member 24 is also connected to the legs 22 by diagonalstays or braces 24 and it is adapted to rest on the ends 10 of the reversible frame members 10 when the frame is folded back into the position shown in Fig. 1. Members 25 and 26 are secured to the members 21 of the folding frame and to each other in triangular relation; and said members 25 and 26 areconnected at their point of juncture by a cross member 27 and the respective members 25 and 26 are connected to said cross member 27 by dia onal stays or braces 25?!1d 26. [The members 25 and 26 being r dly se- 1.10

curedto the members 21, and connected by the cross member 27 and braced by the diagonal stays 25 and 26*, form ,a rigid cross tie and truss for the outer folding frame; and the triangular end members 15, 16 and 17 of the other folding frame which cooperates with the reversible frame and are connected by the cross member 18, also serve to stiffen the structure. It is also preferable to provide a cross member 16 end extensions 16 cent to the pivots 19% The lower end portions of the legs 22 are connected by a cross tie piece 28 so as to resist the tension of the spring mattress support which is connected only to side frame members 21 of the outer folding section, and its tendency is to draw the upper end portions of the legs inwardly. lower portions outwardly,i owing to the location of the cross memand force their ber 24.

The arrangement of-the triangular end: members 9, l0 and 11 and cross members 12 and 13 of the reversible frame gives considerable rigidity to that structure; and it is necessarily required, for the reason that this frame is really the main supporting frame,

while the two others are secondary or auxiliary frames.

The several supporting posts and frame members are preferably constructed of angle irons. This enables the structure to be made light without sacrificing rigidity.

Arontinuous mattress 29 is employed, and it is supported on a suitable woven wire fabric or other flexible spring mattress support, not shown, but which may be obviously secured to the horizontal flanges of the side frame members members being arranged substantially the same horizontal plane, as shown-in Fig. 3. The structure also permits the frames to be folded with the mattress thereon into the position shown in Fig. 1, the portion of the mattress which is car- 16, 9 and 21, said so as to open in ried by the outer frame members21 serving as the cushion for the sofa seat.

position of the device, as shown in Fig. 1, the end extensions 21 of the members 21 rest on the cross member 8 which connects the rear uprights 2 of the stationary supporting frame, while the horizontal flange of the cross member 24 which connects the supporting legs- 22 rests on the upper end portions 10 of the reversible frame members 10.

In the closed The device may be easily opened to the.

position shown in Fig. 3 by merely lifting on the outer frame members and drawing the same forward; and it is closed just as The inner bed section being hinged on the supporting links 19 and pivoted to is brought into posistructure is counterso that there are no sudden tion; and the Whole balanced,

'quired to be released prior to which connects the of the members 16 adjachanges in weight and leverage which would require the person operating the device, either in opening or closing the same, to exercise any special caution. Nor is it necessary to provide any locking means or latches to hold the device in either closed or open position, and, therefore, none are recfi'ecting the openlng and closing of the device.

Obviously, the device admits of considerable modification without departing from my invention. Therefore, I do not wish to be limited to the specific construction and arrangement shown.
