PATENT OFFICE.

The subject of the present invention forms a collapsible bed, which in particular is intended for colonial or military purposes, but also as a sleeping place in the garden or in the open field, as well as in ambulances and so on.

This collapsible bed is characterized by the fact that it rests on the floor by means of beams which extend the entire length of the bed and connect the bedposts to one another. These beams offer a relatively large support surface and enable the bed to be on any floor he being able to sit down soft or ungleichmäfsig without the risk of sinking or tipping. This particular arrangement of the bar offers a great advantage over the commonly used · collapsible cots or other, which always rest on Füfsen that offer little support surface and a Do not prevent sinking into soft ground or tipping over on uneven ground.

Another major advantage of this collapsible bed is its lightness and strength, in the light and simple collapsibility, in the small Clearance requirement of a bed folded in this way and easy handling when putting it together and dismantling. The collapsible bed can also be used as a bench in certain cases by turning the upper side sweeps down.

The accompanying drawings show some embodiments of such a collapsible one Bed.

The collapsible shown in Figs Bed consists of two longitudinal beams, from

Claims (1)

each of which consists of three parts abc articulated to one another by means of bolts ee . Each end of the intermediate part b is provided with a cleat f which adjoins the adjacent part a or c when the bed is spread out. The posts gh, which are hinged to the ends of the beams, can be folded over in an arc by struts i and k, which are rotatably fastened to part b. They are also held in an upright position by cross struts m connecting the posts h and by small struts η holding the posts g . The struts η connect the posts g to the roller o, which is held by the posts. The canvas cover p, which forms the bearing, is attached on the one hand to the roller o and on the other hand to the roller q ; it can be tensioned using suitable devices. The struts i consist of one piece, while the struts k are formed from two parts inserted one inside the other and reinforced by rings u (Fig. 5). The parts abc of each beam are made of U-iron, the interior of which is completely filled with wood (Fig. 6). In order to give the whole beam abc a certain mobility when the bed is empty (Fig. 1), supports d (Fig. 6) of suitable thickness are arranged under the cleats f so that the beam becomes straight under the pressure of the load . On the other hand, in order to ensure the exact position of the spread-out parts from c to one another, the cleats f can be provided with a tenon / (Fig. 6) which comes to rest in a corresponding mortise of the parts α and c. If the bed is to be dismantled, the canvas ρ is removed, the rollers 0 and q are lifted from their bearings, the various arms and struts are unhooked, and the similar bed halves are put together by placing the posts g and h on parts α and c and the latter then turned over to the side of part b ; the whole of each half of the bed folded in this way (Fig. 7) takes up only a very small amount of space. In the embodiment of the collapsible bed shown in Figs. 8 to 13, the part b is connected to the posts g and h rotatably arranged at the ends of each beam by struts r , which consist of two parts held together by means of bolts (Fig. 11). In order to hang each strut r in the plate 5, a resilient pawl t fastened on part b is provided, which is bent upwards so that the knee-shaped bent part u of the strut r is inserted into a corresponding hole in the plate 5 when the former is put on can. The resilient pawls t each step into a groove of the pin u of the struts r and secure the latter in its position of use against self-loosening. Figures 14-19 show a similar collapsible one Bed, with the only difference that the longitudinal beams are wide enough to allow them to be placed next to one another and turning the bed over for a seat supported by the posts like a bench form. Each of the two parts of the same bed is formed from a beam of the wooden of two angle iron held together by longitudinal healing is ν. The posts, struts and cross struts are connected to one another and to the beam in a manner similar to the previously described types of execution. To convert the bed into a bench, the cross braces m are unhooked and the two bed parts are brought closer to one another and the cross braces m are hung in the eyelets w attached to the supports. The bed can then be turned over and used as a bench (Figs. 16 and 17). In order to increase the strength of the bench, coupling parts can be arranged under the beam parts ν. Such an arrangement is shown, for example, by the hooks χ (Fig. 18), which are rotatably attached to one of the beam parts ν and are hung in the eyelets of the other beam part. This embodiment can also be folded up in a simple manner and then takes a very small space, as Fig. ig shows. Figures 20 and 21 relate to an embodiment of the last-described bed; The beams can be rotated in their middle in joints y , so that such a collapsed bed is only half the length it used to be. After the bed has been turned over and converted into a bench, the latter can be given the necessary load-bearing capacity by means of tension pegs or cross braces or other suitable means. In the drawing, the bars are in the center and ν shown below the same pegs \, which serve to receive the clamping wires which are connected to the ends of the beams (Fig. 20). Handles (Fig. 1 and 14) are used to To be able to carry the bed with your hands like a stretcher. Pa τ ent-Ans ρ ruche: i. A collapsible bed, characterized by the fact that it is placed on the floor Rests longitudinal beams which connect the lower ends of the bed posts. '. An embodiment of the under i. called collapsible bed, in which the longitudinal beams consist of three parts (abc) which are connected in such a way that they allow a certain movement when the bed is empty, whereas when the bed is in use, they lie firmly on the floor. · An embodiment of the under i. called collapsible bed, in which resilient pawls (t) are arranged, which each enter a groove of the pin (u) of the strut (r) and secure the latter in its position of use against self-loosening.
An embodiment of the under ι. said collapsible bed, in which the longitudinal beams (v) are sufficiently wide to form a bench-like seat supported by the posts after they have been laid next to one another and the bed is inverted. For this purpose 2 sheets of drawings.
