Application filed Novemli'e'r 2, 1925. Serial No. 66,280.

This invention relates to collapsible and camp beds.

It is an object of the invention to provide a bed which can be collapsed into a very small and compact form and which is of Very light, but substantial, structure and which can: be tended an'd'set up for use.

Anobject is to provide a mattress support which can" be rolled into small form arid is interlocka'ble' with and separable from its complementary bed frame.

An obj set is to providela bed having fold adjusted as a hammock. Figure 2 is a perspective of the bed; the mattress support being broken away. Figure 3 is an end view of the collapsed frame. Figure 4 is an end View of the extended frame. Figure 5 is a.

in perspective of the rail end and its saddle.

Figure 6 is an end view of a saddle. Figure 7 is a perspective of a hinge leaf of the saddle. Figure 8 is a plan of the blank of a saddle.

The bed includes a pair of side rails 2 having at the lower corner ends hinges 3 to which are attached legs 4 which swing down from the rail to an outwardly inclined position. Stout, folding braces 5 connect the legs to the rail for bracing the legs in the extended position.

When extended the upper end of each leg forms a shoulder beyond the rail end and on this shoulder may rest a foldable stub rail 2 which is connected to its near rail by a hinge having its pin 6 in the top plane of the rail so that the stub 2? can be folded over on top of the rail in collapsed form. A hook-brace 7 is pivoted in each leg 4 and its hooked end 8 is insertablein holes 9 and 10 in the stub rail 2 I A pair of rail structures just described are foldably connected in parallel relation by'a r collapsible means of the lazy tongs type.

This means includes a set of link members quickly and very easily ex 1'111* connected'at 12 to struts 13 and pivoted at 14:" on tlie 'upper' ends of opposite legs 4. Levers 177-18 are connected at 19 and are pivoted at 202l near the bottom ends of the legs; t'ogethe rat 22. r

Th'e'refore', as the side rails are pulled away fromeach other, asinFig. 3, the levers 1-7'18' open out intoalinement and automatically move the struts 13 up between the The struts are connected 3- tobr'a'ce the struts andthe legs. lVhenthe" rails have been spread an end stile is mounted on the extended ends of one palr of stubs 2 and the mattress support 26 is I unrolled toward theopposite'en'd of the bed and the other end stile is connected to the relative stubs before these are fully extended.

The stubs are then pulled outward and pressed down to the plane of the rails. This places springs 28 under high tension and theyhold the stubs down on the tops of the legs 4.

The stiles 25 combine with the bottom levers 17--18 to lock the frame in fully spread position.

To permit the legs to fold up close, the lazy tong-linkage on one end of the bed is connected or mounted on the outer faces of their legs while'the linkage of the legs at the opposite end of the bed is on the under face of the legs. The support 26 can be pulled tight by pressing down the end stubs 2 below the center of hinges 6; the springs 28 highly tensioning the fabric and pulling the stubs 2 'down against the tops of the legs 4.

A hammock may be formed by tipping up I the stubs 2 as in Fig. 1, and placing the brace hooks, in holes 10. The edges of the support 26 are wholly free from the rails and may, therefore, freely sag down between the rails and form a very comfortable hammock.

When the end bars 25 are removed the whole frame can be collapsed into a small bundle form, and the support 26 can be-rolled into a small roll. I

To obtain. a very strong structure and good connections for the legs and the stub ends 2*, I provide a saddle forming a central seat portion 30 having upturned side lugs 31 here shown as of triangular form. The top cor-.

11ers of the lugs 31 form bearings 32 for the hinge pins 6. At the outer, lower corners of the seat 30v is'a pair'of bearing ears 3 for the pin 3 of its hinge leaf 3. The pins 3 and 6 are disposed about in the end plane of the rail 2.

The leaves 3 and 6 of the hinges are substantiallyduplicate.

A stout rivet 83 secures the saddle in place on the end of its rails, and, a hole 34: in the.

seat 30 provides for a fastening screw if desired.

W'hatis claimed is: ,1. Abed having side rails and end pairs of legs foldable onthe rails, levers pivoted at their ends on respective pairs of legs and connected together at their inner ends and aiming When extended, struts Whose inner ends are connected and Whose outerends are pivoted on the levers near the pivots thereof, and diagonal brace links connected to the le rs and connected to the struts at points between their ends.

2. A bed havingside rails and end pairs of legs foldable on the rails, levers pivoted at their ends on respective pairs of legs and connected together at their inner ends and ahning when extended, struts Whose inn-er ends are connected and Whose outer ends are pivoted on the levers near the pivots thereof,

and'diagonal brace links connected to the legs and connected to the struts at points betothe levers.

3. An adjustable bed structure including side railshaving on their'ends saddles with bottom seat portions and upturned side hinge tween their ends, and near their attachment pintle plates Which are fixedly secured to the rails;the upper corners of the plates providing bearing lugs for hinge pins, bearing ears at the outer corn-ersof thee-eat portions for hingepins, and hinge leaves pivoted on said'lugs and ears and carrying railstubs movable-into alinenientlivith the rails, and

for hinge pins, an upper hinge leaf anda lowerihinge leaf in respective bearings at the end corners ofthe plates of each saddle an extension rail part carried byone leaf, and a leg carried by thelower leaf;
