Furniture that can be converted into a bed (sofa, bench, etc.).

Patented in the German Empire on October 29, 1920.

The invention relates to a chair convertible into a bed, according to which The front pull-out seat is provided with a hinged widening surface that when converting the furniture is moved by the former. It concerns the arrangement and Design of the widening surface in such a way that it moves when the seat surface is pushed in adjusts ίο into the rear wall surface of the furniture and part of the rear wall of the furniture forms.

The drawing shows an embodiment of a sofa bed set up according to the invention illustrated in graphical representations.

Fig. Ι shows a front view of the sofa as seating.

Fig. 2 shows the sofa after removing the cushions and upholstery (seat, back and side cushions), partly in end and partly in rear view.

Fig. 3 is a view similar to Fig. 2,

only that the two parts of the folding frame are erected so that they are in one plane lie.

Fig. 4 shows the sofa in front and front S view prepared as a bed; the after The spring frame pulled out at the front has swung down into the horizontal position on the support frame; the covering of the frame but is omitted in the drawing to show the

ίο the parts of the sofa underneath it better to reveal.

The sofa as such can be made in any size, shape and equipment in the usual way and the cushions a, b, c (Fig. 1), with which the seat, the backrest and one or both side rests are covered, a simpler or more elegant Have get-up. Above a bottom of the sofa designed as a box d (Fig. 3 and 4) to hold bedding (sheets, blankets, pillows, etc.) is a frame-like pull-out or support frame e on the front, on which one of the is exposed two existing folding frame with f articulated parts g and g ^1. Both parts have a common, spring-loaded covering of a known type. When the sofa is used as seating furniture, the support frame and the spring frame are in the pushed-in position shown in FIG. The hinged part g ^{1 of} the spring frame hangs down freely between the two rear posts, the transverse wires of the frame covering being supported on the upper edge of a board h or the like in the manner shown in FIG. This support board, which is arranged slightly in front of the back plane of the sofa and prevents the part of the covering serving as a seat from sinking in, is provided with cutouts at its upper corners, into which the transverse parts of the two frame parts g and g ^{1 lead} when they are pulled out and pushed in. To stiffen the spring frame in itself, the transverse parts of part g are expediently by a

Metal bracketsH connected to one another. ;

Converting the sofa into a bed ^!

instead of happening in the manner evident from the figures in the drawing by first removing the cushions a, h, c (Fig. 2),! then pulls out the support frame e and lifts part g of the spring frame, whereby part g ^{1 will} straighten up by itself J as a result of the tension exerted by the spring cover I and will align itself with part g (Fig. 3). To connect the two frame parts g and g ¹ in the plane, a snap device can also be attached to the hinge points f , which spring in as soon as the folding part g ^{1 is} erected and which are triggered by means of a push button or the like can, if the folding part: should swing down again. Such locking devices are recommended if the frame parts g and g ^{1 are designed} as rigid surfaces. Then the bedding is: taken out of the box d and the folding frame g, g ¹ set in the plane is pulled forward j and placed in the horizontal position on the support frame e (Fig. 4). j After placing the pillows a, b (the pillow b j inside, the pillow α outside) as a longitudinally divided mattress on the spring frame, the pillow c as a wedge pillow and the rest of the bedding, the sofa is then prepared for use as a bed.

The conversion of the bed to a sofa is done in reverse order.

Finally, the design can also be chosen so that the folding frame is replaced by a single surface made in the manner of a roller blind, which can be run at the rear over the support board i or another equivalent support device (rod, roller or the like). The part of the blind that is not used for the seat then hangs down loosely at the back or can also be wound around a suitable roller.

Claims (3)

Patent Claims: 1. Seating furniture which can be converted into a bed (sofa, bench or the like), the forwardly extendable seat of which is provided with an articulated widening surface which is moved through the former when the furniture is converted, characterized in that the widening surface (g ¹ ) forms a rear wall of the furniture when the seat (g) is pushed in. 10a 2. Seating furniture according to claim i, characterized characterized in that the widening area is designed as a roller blind. 3. Seating furniture according to claim 1, characterized in that the seat (d) and its widening surface (e) consists of an extendable, longitudinally divided folding frame (g, g ¹ ) with a common, flexible covering which, when the folding frame is extended, has its entire width · forms an unobstructed lying surface, but when the folding frame is pushed in, it folds with the folding frame part (g ¹ ) around a support rail (h) or the like in order to form a supported narrower seat surface. 1 sheet of drawings.
