This invention relates'to a foldable and collapsible bed, such as'used by campers,

tourists, and the like, and particularly, to a mattress for said bed which is secured to a tensioned flexible sheet, such as a. sheet of canvas. In beds of the prior art where a tensioned sheet or mattress is used the tension has often been applied to the mattress. This destroys and tears the mattress and renders the same objectionable for sleeping purposes. If the supporting. or tensioning means are not secured to the mattress the mattress is apt to contract and become crumpled and lumpy. I

It is an object of this invention, therefore, to provide a collapsible bed structure including a tension flexible sheet having a thin mattress secured thereto which is adapted to be rolled or folded with said sheet, the mattress being slightly longer than the sheet so that suflicient slack is provided thatwhen the sheet is tensioned the mattress'will not be under tension.

It is a further object of the invention to provide a collapsible'bed structure comprising a flexible sheet having tensioning means secured adjacent each of its ends, which means are supported by said bed, together with a mattress secured at its ends to the ends of said sheet, the end portions of the sheet and mattress overlapping the tensioning means.

It is more specifically an object of the invention to provide such a structure as set forth in the preceding paragraph in which said flexible sheet is provided with spaced longitudinallyv extending reinforcing portions, and in which the tensioning means is secured to rods disposed, respectively, at each end of said sheet and loosely secured thereto, said rods preferably being secured in a loop formed by folding the mattress.

These and other objects and advantagesof the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which Fig.1 is a view in side elevation of the device, a small portion being shown in verti-- cal section;

Fig. 2 is a top plan view of the device with certain portions broken away to show the underlying parts;

Fig. 3 is a vertical se'ction taken-on the hne 33 of v Fig. 2, as indicated by the arrows;

Fig. 4 is avertical section taken on the line H of Fig. 2, as indicated by the arrows; I

Fig. 5 is a vertical section taken on the line 5+5 of Fig. 2, as indicated by the arrows; and i Fig. 6 is avertical section taken substan tially on the line 66 of Fig. 2, as indicated by the arrows, Figs. 3 and 6 beingshown' on an enlarged scale.

Referring to the drawings, a bed is shown comprising'a frame having connectible end portions, each of which comprises an end bar 7 which may be formed of pipe or tubing and which, has at each end thereof, a bifurcated member 7*. Side bars 8 are pivoted to the portion 7 on vertical pivots and leg members 9 having the forked or bifurcated members 9 at their upper ends are pivoted to the members 8 adjacent the member 7 about horizontal pivots. The members 8, at one end of the frame, are formed with pointed ends 8*, While the ends of the members 8, at the other end of the frame, are formed with concave portions 8 in which the ends 8 are adapted to fit and form a substantially universal joint. A sleeve 10 is slidable on the bars 8 so that it may be disposed over the adjacent end portion of the members 8, as shown in Figs. 1, 2 and 6.

A flexible sheet 11 of fabric material, suchas strong canvas, is provided and this sheet, preferably is provided with spaced longitudinally extending reforcing portions. While these portions may be variously formed, in the embodiment of the invention illustrated, they are shown as formed by folding the canvas to form a double or reverse fold or plait 11 held in such shape by spaced longitudinal rows of stitching l1". A rod 12 is loosely secured to the sheet 11 adjacent each of its ends so as to extend transversely thereof, and while this rod may be variously secured, in the embodiment of the invention illustrated, it is shown as disposed in a loop fold 11 formed by folding the sheet 11 transversely in a reverse fold and securing said fold by a transverse line of stitching 11. At one end of the sheet 11 a series of tensile springs 13 are provided having one of their ends formed as hooks and extending around the rod '12 through the loop 11. It will be noted that certain of these springs are alined with theportions 11". The springs are secured at their outer ends by headed and nutted screws 14 to'split rings 15 which embrace the rod 7. At the other end of the bed .the rod 12 is embraced by a series of chain links 16 forming the inner end links of chains 16, the outer end links of which are secured to split rings 15 which are similar in construction to the rings 15 already described and secured to the said end links in the same manner as the ends of the spring 13 are secured. The end portions of the sheet 11 extend over the springs 13 and rods 7 at one end of the bed and over the chains 16 and rod 7, respectively, at the other end of the bed. A comparatively thin mattress 17 is provided which, preferably will be provided with the usual tufts 17, which mattress is adaptd to be folded or rolled up. The mattress 17 is slightly longer than the sheet 11 and is secured at its ends to the end of said sheet in any suitable manner, as by the line of stitching 18.

In operation, when the bed is to be erected, the ends of the members 8 will be engaged, the sleeve 10 atthis time being entirely on the members 8 at one end of the bed. The ends of the members 8 bein engaged and the legs disposed downward y, as shown in Fig. 1, the members 8 can be pressed down into horizontal position and the sleeve 10 slid thereover, so that the canvas 11 will be tensioned. The tensioning stress is transmitted to the rods 12 and by the rods to the sheet 11. As stated, the mattress 17 is somewhat longer than the sheet 11 and slack is provided so that when the sheet 11 is under tension the mattress will not be under tension but will simply lie in proper and loose condition on the sheet, the ends of said sheet and mattress overlapping the springs 13 and the chains 16, as well as the bars 7, as already described. The bed is now in condition for use and a pillow or other similar means can be placed under one end of the sheet 11 and mattress 17.

When the bed is to be colla sed, the sleeves 10 are slid onto the mem era 8 at one end of the frame so that the bars 8, at each end, can be swung at an angle and disconnected. Each bar 8 will then fold along one of the end bars 7, the le 9 also folding along the bars 8. When t e parts are so folded the same can be rolled up with the sheet ll'and mattress 17 so that the whole structure can be collapsed into a very small volume. If the sheet 11 or spring 13 should become somewhat extended sothat sufiicient tension is notprovided, a link can be taken up in the chain 16 so that pro er tension can then be secured. The rein orced portions' 11 of sheet- 11 insure that the said sheet can be highly tensioned without any damage or danger of tearing and "these reinforcin portions form spaced supporting zones. 7 he mattress 17 not being place under tension and yet being held properly in place, is not damaged or unduly stretched so as to get out of shape and thus remains in proper and comfortable condition for a long period. From the above description it is seen that a plicant has provided a very simple and e cient, as well as durable folding bed andmattress structure therefor. The device has been amply demonstrated in actual practice and found to be very successful and is meetin with great commercial favor.

It will of course, be understood, that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of applicants invention, which generally stated, consists in a device capable of .carryin out the objects above set forth, in the nove parts and combinations of parts disclosed and defined in the appended claims.

What is claimed is 1. A- folding bed'structure having in com.- bination, a flexible sheet of fabric material, a support-spaced from each end thereof, a series of spaced means secured adjacent each end of said sheet and secured at their opposite ends, respectively, to said supports, one of said series of means being resilient, and a comparatively thin foldable mattress permanently secured at its ends to the ends of said sheet with suficient slack so that when said sheet is tensioned, said mattress will not be under tension.

2. A collapsible bed structure having in combination, a flexible sheet of fabric material having spaced longitudinally extending reinforced portions, a series of spaced tensioning means secured adjacent the ends of said sheet and alined with said portions, one of said series being resilient, and a mat tress permanently secured to the ends of said sheet, said mattress being slightly longer than said sheet whereby said mattress is not tensioned when said sheet is ten- .sioned.

V 3. A collapsible bed structure having in combination, a flexible sheet of fabric material, a rod extending transversely of said sheet adjacent each end thereof and loosely secured thereto, the end portions of said sheet extending beyond said rod, a mattress of slightly greater length than said sheet having its ends permanently secured to the ends of said sheet, and tensioning and su portmg means secured to said rods and disposed beneath the end portions of said sheet and mattress.

4. A collapsible bed structure having in combination, a flexible sheet of fabric material, said sheet being reversely folded and transversely stitched adjacent each end to form a transversely extending 100p, rods disposed respectively in said loops, spaced tensioning and supporting means embracing each rod and extending therefrom, the ends of said sheet overlying said tensioning means, and a comparatively thin mattress tress so that when said sheetis tensioned W said mattress will not be tensioned.

In testimony whereof I afiix my signature.
