foot stirrup, and thehead prop being made from U-shaped bent steel tubes, by the articulations consisting of two plates each, one platebeing fastened to either side of the steel tubes, by the U-shaped stirrups, constituting the feet of the bed, being deflected in their webs so that these foot stirrups only rest on the floor with their curved parts, and by the stirrup forming the middle foot being stiffened by struts. Furthermore, these aims are attained by welding an undulating wire to the U-shaped steel tube stirrups, forming the bed frame and the head prop, said wire being provided with rests between the welding points for hooking in the ends of coil springs, the other ends, of which are fastened to the canvas or the like. Finally, the bed frame is also provided with tiltable rods for the fixation of mosquito-nets.

The drawing annexed discloses theinvention by way of two embodiments; Fig. 1 being a bird's eye view of an embodiment of a camp bed in the position of use, whilst Fig. 2 shows the same camp bed inthe collapsed state, and Fig. 3 represents the mode of fastening the foot stirrup to the bed frame, Fig. 4 is a section taken on the line IVIV of Fig. 3. Fig. 5 shows the connection of the two bed frames. Fig. 6 is a section taken on the line VIVI of Fig. 5. Fig. 7 shows the mode of fastening the undulating wire to the U-shaped frame, and the canvas hooked in by means of coil-springs. Fig. 8 is a section taken on the line VIII-VIII of Fig. 7 on an Fig. 9 is a lateral view of the camp bed, as bed for the tropics fitted with props for carrying the mosquito-net. Fig. 10 is a frontal view of the camp bed according to Fig. 9. Fig. 11 shows the bed according to Fig. 9 in the collapsed state, whereas Fig. 12 is a view from above on the bed according to Fig. 9-. The bed frame according to Figs. 1 and 2 consists of two U-shaped stirrups I and 2, made from bent steel tubes, their free shanks being connected by articulations. The connection is effected by the two plates 3, one on either side of the steel tubes, and the bolts 4 and 5 about which the stirrups 1 Claim. (Cl. .5-117) 'tiltable about the bolt 2I.

I and 2 canbe tilted. The stirrup 9, constituting the middle foot of the bed, is fixed by means of rivets I between the two plates 3 according to Figs. 5 and 6. Said stirrup is provided with a web 8 bent upwards and is stiiiened by the struts 9.

To the stirrup 2 the stirrup II! forming the front foot islinked so as to be tiltable about the bolt I4. The stirrup I9 hasa web I2 bent upwards so that it can only rest on the floor with its curved parts I3. Said stirrup III is fixed by riveting between the two plates I I, said two plates II being connected by the bolt I4 with the tubular stirrup 2 on both sides of the tube of the stirrup 2. I

To the stirrup I the stirrup I5, constituting the rear foot is, according to the Figs. 3 and 4, fastened by means of the plates I6 so as to be The stirrup I5 has again a bent-up web II. Besides, to the stirrup l the stirrup I8 is linked, serving as prop for the head, by means of the plates I9 so as to be tiltable about the bolt 20.

To the U-shaped stirrups I, 2, and I8 undulating wires 22 are welded at the points 23 so that between said welding points rests 24 are formed into which the ends of the coil springs 25 are hooked, whilst the other ends of said coil springs are fastened to the canvas 26. According to the weight of the person utilizing the bed, the number of said coil springs can be increased, and additionally several coil springs may be hooked in at the points at which the canvas is more heavily loaded as is seen at 25 in Fig. 7.

The bed is folded up as seen in Fig. 2, and is kept in that position by means of a strap 21, or the like. I

According to the embodiment revealed in the Figs. 9-12 the U-shaped stirrup I8, forming the head prop is tiltably fastened within the stirrup I by means of the articulations 3I and can be arranged in an oblique position by means of the toothed strut 28 and the bolt 29. At their curved portions the stirrups I and 2 are connected by welding with the short supports 39 to which the rods 32 are tiltably fastened by means of hinges 33, said rods being kept in their upright positions by means of struts 34. According to Fig, 10 said rods can be formed into U-shaped stirrups 'and be used for carrying the mosquitonets. The bed according to Figs. 9 and 10 is made to collapse as shown in Fig. 11.

It is a further advantage that all parts of the bed are connected by means of articulations, and that there are no loose parts which hitherto had to be kept separately and had to be stuck on the bed fitted up.

What I claim is:

In a folding bed having a frame formed of two pivotally connected U-shaped members with support elements pivotally connected to each said member and a head rest pivotally mounted on one said member, the improvement comprising said head rest comprising a U-shaped frame pivotally mounted at its ends to the sides of said one frame member, undulating wires having spaced bends of greater length than intermediate bends, said Wires being fixed by welding said greater bends to the inner sides of said head rest frame and said one frame member between the pivotal connections thereof to the head rest frame and to the other said frame member, a body support web, a plurality of springs connected at one end to the edges of said Web and selectively hooked at their other ends in selected lesser bends of said undulating wires, said support elements com- '4 prising U-frames having their ends pivotally connected to the sides of said frame members and in the plane of each side for abutment therewith in supporting position and solely propped by said abutment.
