SOFA-BED.

Specicatioil of Lettera Patent.

Patented June 25, 1918.

Application led January 2, 1912. Serial No. 668,946.

To all whom t may concern.'

Be it known that I, CHARLES J. KINDnL, a citizen of the United States, residing at Wilmette, in the county Vof Cook and State of Illinois, have invented new and useful Improvements in Sofa-Beds, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to improvements in sofa-beds, and more particularly to that class thereof employinga plurality (more than two) lbed-frames in its mattress-support.

The principal objects in view are to con struct, in a bed of this class, a mattresssupport wherein the bed-frames composing the same are so relatively arranged, as well as connected, that when folded they are adapted to be stored in the sofa-bed frame and below the seat thereof and when unfolded they combine to constitute a continuous practically unbroken mattress-supporting surface, and wherein, .1n both the operation of folding and unfolding, the plurality of frames composing the bed are successively operated and continuously. inthe same direction; furthermore to provide 1n a sofa-bed suitable supports for the several frames composing the mattress-support or bed while extended into bed-form as well as when folded and stored, as well as means for locking the outer frames together during a manipulation thereof either in the act of closing or unclosing or folding, and also means for properly and relatively spaclng the frames apart when folded whereby the mattress and bedding too, if desired, may be folded and stored with the bed-frames below the seat of the sofa.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings: n

Figure 1 'is a plan view, partly 1n section, and with parts broken away, of a sofa-bed embodying my invention. l

Fig. 2 is an end-elevation of the same, the Sofa-end removed, and the mattress-support opened and in position for use as a bed; the mattress-support also being shown partly folded by dotted lines;

Fig. 3 is aview similar to Fig. 1, the mattress-support being shown completely folded and stored within the sofa-frame;

Fig. 4: is an enlarged detail sectionalview hereafter referred to Similar numerals of reference indicate similar parts in all the figures of the drawings.

Referring to the drawings more in detail and forthe purpose of describing a practical embodiment of the invention, it will be seen that I employ a conventional form of sofa-frame, wherein are embraced a pair of sofa-ends l, and a connecting back-board 2, the latter, as is usual, extending above the ends, and in this design of sofa-bed, terminating above the ends in an upholstered section 4 and constituting a convenient head-rest, and when the sofa-back is in position for use as such, a part of the same. To bring the head-rest to a proper position, the same may be supported at the front of a ledge 3, extending forwardly from the back-board 2 of the frame.

The mattress-support, and with this my invention principally has to do, comprises, in the form illustrated, three bed-frames pivotally connected in series and so that` they will both fold and unfold with respect to each other successively as well as continuously in the same direction; and so that, further, when unfolded or open, there will be presented a practically unbroken mattress-support at a proper elevation for convenient use as a bed, and when folded the frames will be compactly and relatively arranged, whereby, not only are they all stored within the sofa-bed frame below the seat, but are alsol locked together, certain of them, to facilitate manipulation, and are relatively positioned so as to permit of the bedding being folded and stored therewith.

The mattress-support comprises, in the present embodiment of the invention, three bed-frames, designated as 5, 6 and 7 or, in other words, the main, the intermediate, and the foot-frames. The main-frame 5 is arranged within the sofa-bed frame, and is formed sectionally, comprising bars 8 and 9, pivotally connected, as shown at 10, and

is supported from bars 11, removably arrce said frame may be adjusted or folded with respect thereto. For this purpose, a pair. of

rear links 12, may be pivotally connected at the rear ends of the bars 11, and also with 5 the frame-bars 8, near therear ends ofthe latter, and a pair of front links 13, are connected with the bars 11, near their Jfront ends, and pivotally connected with the frame-bars 9, at their front ends, as indicated at 14:. The bars 11 may be supported in osition by suitable lugs or castings 15, secured to the sofa-ends 1, 4and v inclined braces 16, may be pivotally connected at their ends to the bars 11 and the links 13, for reinforcing and bracing the latter.

A front-board 17, may be arranged at the base and front of the sofa-frame to partly closethe same and thus conceal the parts in rear thereof.

The intermediate bed-frame 6, is pivotally connected with the frame-bars 9, of the frame 5, as at 14, and, in the present design of sofa-bed, constitutes a support for the sofa-seat 18, the frame 19, of the latter, being supported some distance therefrom, by means of rigid standards 20.

If desired, the links 13, may be additionally supported at their upper ends, by clips 21, secured to the inner sides of the sofa-ends- 30 The side frame-bars of the intermediate frame 6, are preferably curved upwardly (when the parts are unfolded as in Fig.. 2) or made quadrant-shaped,as indicated at 22, andthe adjacent ends of the side framebars of the outermost or oot-frame 7, are similarly disposed, as at 23, the curved ends of these two sets of side or frame-bars being pivoted together, as at 24.

The outermost or footframe 7 is adapted to be folded rearwardly upon the middleframe 6, against that side thereof opposite which the sofa-'seat 18 is located, and lone or more yielding latches, as, for instance, 25, may be pivotally connected intermediate their ends to the side frame-bars of the footframe 7, as at 26, and adapted to engage over suitable corresponding catches, as pins 27, projecting from the middle or intermediate frame 6, whereby, these two frames 50 will become locked when folded to the position shown in Fig. 2, and thereafter may be turned or manipulated as one element. The latches may be controlled by springs 28, connected to the same above their pivotpoints and to the side frame-bars of the frame 7, and said latches, below their pivotpoints, or otherwise, it desired, may be connected by a rod 29, which will serve as a convenient handle for simultaneously op-y erating the latches to disconnect vthe same from the catches when necessary. A stoplug 30, may project from each of the frame- 'bars of the frame 7, whereby td maintain the latch at a suitable angle against its spring.

navegar The outer or foot-frame 7, is, of course, intended to be supported upon suitable legs,` the same being arranged to be folded'out of the way when not in use. In the present instance, legs 31, are pivotally connected at the sides and near the outer end of the frame 7, as at 32, and these I arrange to automatically foldand unfold with respect to the foot-frame 7 and during the folding and unfolding movement of the same, by means of leg-operating links 33, pivotallyl connected to the respective legs, as at 34, and eccentrically with relation to the pivots 32, and also pivotally connected at their opposite ends, as at 35, to short links 36, carried by the intermediate frame 6. rlhe pivots 35 are eccentrically locatedwith relation to the pivots 24e, so that when the frames 6 and 7 are folded into the position shown. by dotted lines in Fig. 2, the legs 31 will he held B5 against pivotal movement.

In the present instance, the sofa-seat 18 is provided with an upholstered back-section 37, the latter .being rigid with the seat,and the former positioned as described with respect to the intermediate-frame 6, the upper or free edge of the back will, when the bedframes are opened, serve as a support .for the intermediate-frame 6. This backfis so proportioned and designed with respect to the other parts having relation thereto, that when the parts are adjusted to sofa-form, as in Fig. 3the free or the then upper edge of the back' will pass below the adjacent edge of the head-rest 4:, combining with it E06 to form a conventionally appearing back for the sofa. The mattress-'supporting bedstructure l have described, is not necessarilyy intended for use in connection with this style of sofa, that is, one wherein the seat and back turn and the latter, constitutes a support for the intermediate-frame. To the contrary, l have merely suggested support# ing the intermediate-frame by the sofa-back as one means thatmay be used, but it will 1w be obvious that any other desired. means may i be substituted.

Helical springs 39, are disposed between 'the frames 5 and 6, connecting the rear ends of the frame-bars of the former with the .L15 front ends of the frame-bars 8 of the lat? ter, such springs serving as a means for as` sisting in the unfolding operation of. the structure, as is more fully described in my Patent No. 1,065,373. 120

A continuous elastic mattress-supporting surface 40, of any well-known woven-wire design, issecured in the/usual manner tothe frames 5, e and 7, such mattress-support being omitted in some figures of the drawing, i

for the purpose of clearness.

The sofa-seat may be provided with the usual springs 4l, (see Fig. 4), and is adapted, when unfolded, to assume aposition with respect to the remaining bed-frames at the E3@ point where the greatest Weight or strain usually occurs upon the .wire fabric when the bed is occupied. In order, therefore, to more thoroughly and yet yieldingl y reinforce the fabric at this point, a bank of doubly coiled springs 42, may be mounted to project beyond the ends of the springs 4l and the frame 19, so as to ellgage and support the wire fabric as clearly shown in Fig. 4.

A flexible apron 43, may be provided to form a closure at the front of the sofa-frame between the edge of the seat-frame and the top of the front-board 17, when the sofa is folded.

It will, of course, be understood, that the several bed-frames are rectangular in plan, and preferably constructed of angle-iron, the frame-bars thereof being so connected as to enable the frames to break joint in one direction only, all as is usual in this class of beds.

Moreover, the sofa-frame, in order to lend rigidity, may be suitably braced, as for instance, by diagonal braces 44. So also, may the seat-frame 19 be formed of angle-iron, withinsueh frame being arranged the usual filler 45.

Assuming the parts to be in the position shown by full lines in Fig. 2, the bed is closed by the following operation: The foot frame 7, is swung upward and rearward, .whereby to bring it over and upon the intermediate or adjacent frame 6. During this movement of the foot-frame 7, the links 33 being held stationary at their inner pivoted ends and moving in an eccentric circle at their outer ends, will cause the legs 31 to move upon their pivots 32, into the position shown by dotted lines, Fig. 2, against the upper side of the frame 7. By this time, the latches 25 will have engaged automatically with the catches on the intermediate-frame 6, thus locking as well as spacing the two frames 7 and 6, so that thereafter they are capable of turning or being manipulated as one. The thus partly closed bed will, in the present construction, be partly supported by the inverted back. To continue the operation of closing the bed, the two frames 6 and 7 are swung upward and rearward and over upon the main-fra1ne 5, during which operation the frame-bars 9 of the mainframe break joint with the frame-bars 8 thereof, and swinging downward upon their pivots 10, assume substantially a vertical position. This movement of the frame 6 will be against the tension of the helical springs 39, which tension may be later uti.y ized to aid in the subsequent unfolding operation of the bed. As the frarnebars 9 assume the 'vertical position mentioned, the

.main-frame 5, together with the frames 6 and 7 will lower to and within the base of the sofa-frame and at a point near the bottom thereof, the rear supportmg-links 12 swinging forward and downward at their upper ends and thus permitting. the lowering of the bed-structure andv serving to guide the same during such movement. By the time this point of the closin operation has been reached, the upholstered seat will have become reversed and occupy its normal position upon the upper side of the frame 6, which, as will be seen, will now be uppermost in the series. As will be perfectly obvious, a reversal of this operation will again adjust the sofa-bed in bed-form. The mattress, it will be observed, opens, closes and folds with the bed-frames and is stored therewith in the base of the sofa-bed frame.

Both during the folding and unfolding operation of the mattress-support, it will he seen that the bed-frames are not only successively operated, but also, are continuously operated or moved in the same direction, and as a result of this successive as well as continuous operation of the frames in the same direction, when the frames are folded and occupy their stored position in the base of the sofa-bed, the main-frame, or a part thereof, is at the bottom, the intermediatc-frame is at the top, and the footframe is spaced from and 1n between these two, this forming, so far as I am aware, a new and distinctive type of sofa-bed.

Having described my invention, what I claim, is:
