FOLDABLE BED COUCH.

Application filed November 13, 1922. Serial No. 600,651.

This invention relates to foldable bed couches, and particularly to the type of foldable bed couch described and illustrated in my copcnding application. Serial No. 528,286, filed January th, 1922, which has eventuated in Patent No, 1527416, Feb. 24, 1925.

The invention relates generally to a foldable bed couch and particularly to a bed couch adapted for use in connection with a divan or the like, whereby the bed couch in it collapsed position is capable of being moved under the seat of the divan, and which, in its extended position, is adapted to constitute a bed with the seat of said divan.

()ne of the features of importance of this invention resides in the brace members arranged along two sides of the bed frame, which are adapted in their operative position to maintain the bed frame in its extended position by preventing the fold ing of the same. These brace members are 50 arranged that they may be moved to inoperative position and be thereuaon folded with the bed frame so that the ed may be reduced to a collapsed position.

lVith these features in mind, the invention consists in the novel combination, construction and arrangement of parts more fully hereinafter described, especially when considered in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of the bed in open position, certain parts being broken away;

Fig. 2 is an enlarged end view of the parts in folded position;

Fig. 8 is a side view of the foldable bed with thesections in extended position;

Fig. 4 is a fragmentary plan view, showing the connection between the brace mem bers and the bed frame; and,

Fig. 5 is a fragmentary elevation of a corner of a bed showing a detail of construction.

Referring now more particularly to the drawings wherein like reference characters indicate like parts, it will be noted that there is illustrated a divan or the like 10, having a seat portion 11, under which the foldable bed about to be described is adaptcd to be placed when in its collapsed position. However, as the description proceeds it will be apparent that this invention is not limited in its use to the combination with the divan, inasmuch as it may be employed with equal facility as a wall bed.

The foldable bed consists of a supporting bed frame 14 is formed in two sections 15,

which are joined together by hinge connections 16. arranged at the center so that the bed frame sections 15 may, in collapsed position, be folded one upon the other.

The bed frame 14 is formed preferably of angle bars, as clearly illustrated, and is connected to and supported upon the supporting frame 12 by sets of parallelogram links or members 17 and 18, arranged at both sides of the bed frame. The lower ends of both sets of links are pivoted to said supporting frame and the upper ends of said links are pivoted to the said bed frame.

The upper end of one set of links is provided with an extension which is pivoted as at 19 to a link member 20. The other endof the link 20 is pivoted as at 21 to the bed frame, and as at 22 to a link 23, having pivotal connection with the leg 24 which in turn is pivoted to the-bed frame, whereupon, during the unfolding of the bed the leg 24 will be moved to its operative position, as clearly illustrated in Fig. 1. The link connections just described are duplicated at each end of the bed frame, ,aswill be immediately apparent.

From the structure thus far described it will be apparent'that the bed frame sections 15 may be folded one upon the other, and the two bed frame sections then moved to a collapsed position upon the supporting frame 12, as is clearly illustrated in Fig. 2. This is possible by reason of the parallelogram connecting links, 17 and 18, heretofore described. It will be also obvious that during the collapsing of the bed frame the legs 24 will also be moved to a position substantially parallel with the folded bed frame sections.

A spring mattress 26 of the cross lace variety, is employed, which is secured to the bed frame 14, thus causing a stress upon the frame in both directions, thereby equalizing the strain and maintaining the bed in its required shape. For assisting in the bracing of the bed frame there is provided at each corner an angularly disposed cross brace 27, which is secured at its ends at 28 to the bed frame sections. These braces also assist in preventing a distortion of the bed frame be cause of strains.

F or locking the bed frame in its open position there is provided, preferably at each end thereof, a pair of angular brace members 29 and 80. These members are substantially U-shaped and are connected together at their abutting sides by means of a hinge 31. The hinge of each pair of braces is arranged substantially in line with the hinged connection 16, upon which the bed frame sections 15 fold. Each pair of braces 29 and 30 is further pivot-ally or hingedly connected to the bed frame as at 32, so that each pair of brace members may be swung about its pivot downwardly, whereupon the bed may be folded, the brace members in this instance folding at their hinged connections 31. Obviously in setting up the bed the brace member 29 may be grasped and the pair of braces moved to the position illustrated in Fig. l, whereupon the brace members are prevented from collapsing at the hinged connection 31 and securely brace the bed frame and prevent the same from folding or collapsing. These brace members also materially strengthen the bed frame and impart thereto a degree of rigidity sufficient to withstand the normal strains imparted thereto.

From the foregoing it will be immediately apparent that a foldable and collapsible bed is provided which in its collapsed condition is reduced to a compact size convenient for storing, whereupon it may be either placed under the seat of a divan, or may be moved against a wall, or stored in a closet.

Furthern'iore, the bed may be quickly and easily unfolded and set up for use, and positively prevented from collapsing and thoroughly reinforced and braced by means of the pairs of brace members disposed at each end and associated therewith.

Obvious modifications may suggest themselves and to this end reservation is made to make such changes in the specific form of the invention illustrated as may come within the urview of the accompanying claims.

I aving thus described the invention what is claimed is:

1. In a foldable bed, a supporting frame, a bed frame, said bed frame being formed in sections hinged to fold upon itself, means for extensibly supporting said bed frame upon said supporting frame, a brace member pivotally connected to said bed frame at each end thereof, said brace members each com prising two sections hinged together to fold only in one direction whereby said brace member may fold with said bed frame, said braces adapted in their operative position to prevent a folding of said bed frame and an outward displacement of the endsof said frame.

2. A foldable bed of the class described comprising a supporting frame, a bed frame formed in sections adapted to be folded upon themselves, means for mounting said bed frame on said supporting frame, and brace members pivotally connected to said bed frame at each end thereof, each of said brace members comprising a pair of abutting U shaped members, hinged at their abutting sides and adapted to fold in but one direction whereby they may limit outward movement of the ends of the said bed frame.

In testimony whereof, I affix my signature.

OTTO KONRAD.
