This invention relates to a folding cot, suitable for camping purposes, which can be quickly and easily set up and folded and which will fold compactly so that it can be readily handled and transported.

In carrying out the invention, I provide a pair of side rails composed of channel bars, each rail comprising three parts, namely, a relatively long central bar and two end bars of shorter length having forked ends which straddle the central bar and which are pivoted to it, a short distance from its ends. Legs are pivoted within the central bar, at the ends of the latter, and these are provided 1 with slots or notches near their pivotal points. Sliding bolts are secured to the end bars and adapted to enter these notches when the cot is being set up. These bolts lock the end bars and the legs so that the legs cannot fold and the end bars cannot move upwardly or downwardly except by releasing the bolts. The pair of legs at each end of the cot are connected together by folding toggle levers, and a suitable fabric is detachably con- 'nected to the end bars of the frame. When the cot is folded the channeled end bars fold over the backs of the central'bars and the legs fold within the central bars, and the toggle connections between the legs at opposite 30. sides of the cot fold and permit the side bars tolie close to one another.

In the accompanying drawings,

Fig. 1 is a top plan view of the cot set up, a part only of the mattress frame being '3 shown,-

Fig. 2 is a side elevation ofthe same; Fig. 3 is a detail view, on a larger scale, showing parts of a side bar, an end bar, and a leg in central longitudinal section, and a 4 part of the mattress frame in cross section;

Fig. 4 isan end view of the cot, set up; Fig. 5 is a side view of the cot, folded; Fig. 6 is an end view of the cot, partly folded;and,

1F ig. 7 is a perspective view of detached portions of a side bar end bar and leg,- and of a cross bar of the mattress frame.

Referring. to the drawings, the, frame of the: cot comprises a pair of side rails a, a, eachalike-in construction and each composed of a relatively long central bar 1 and end bars 2 and 2 which are connected to the central bar, by pivots 3, a short distance from the ends of the latter bar. The several parts of the side rails are composed of channeled steel, the central bars 1 having their open sides facing down-ward when the cot is set up, and the end bars having their open sides facing upward when the cot is set up. The end bars are of slightly greater width than the central bar. As shown in the detail views, Figs. 3 and 7, the end bars have their back portions removed for some distance from their pivotal points, leaving forked ends 2 which straddle the central bar. Legs 4, 4: composed of channel steel, are connected to the ends of each central bar by pivot pins 5. The legs are of slightly less width than the width of the central bars of the side rails and are pivoted within the central bars, so that they may fold therein. The open sides of the legs connected with each side rail face one another, and in the back of each leg, close to its upper end, is formed a slot 6, adapted to receive a sliding latch or bolt 7 secured to the back of the adjacent end rail. Each bolt is arranged within a suitable guide 8, attached to the end rail, and it is pressed toward its locking position by a spring 9.

v When the cot is set up, these bolts lock the end bars to the legs so that the latter cannot fold and the end bars cannot be moved upwardly or downwardly with respect to the legs or the central bars.

The end bars are provided with adjustable channelled parts 2 at their outer ends, and

these parts are slotted at their ends, as shown at 2, to receive studs 10 on cross bars 10 which support the wire mattress b. As shown these crossbars are of U-shape in cross section and hook over the ends of the adjustable parts 2 of the end bars. Each part 2 has a suitable number of spaced openings 2, through which a bolt 11 may be inserted to hold the part in, anyposition of adjustment. The purpose of this adjustment is to apply the proper tension to the mattress when the cot is setup. 4 I

The pair of legs at each end of the cot are connected together by toggle levers 25, eachv consisting of two relatively long levers12,

pivoted, as shown, near the upper ends of the legs and pivotally connected together at 13, and two shorter levers 14, pivotedto the legs near their lower ends and to the ends of the levers 12, the arrangement being such that in folding the cot, the joints between the i levers '12and 14 will break downwardly.

When the cot is knocked down, the end bars 2, 2, fold over the backs of the central bars 1, as shown in Figs. 5 and 6, and the legs fold within the central bars, the toggleslying' flat against the legs, as shown in Fig. 5. In setting up thecot, the legs are first unfolded,

as shown in Fig. 6, the cot lying on its side, and the side rails are then pulled apart upwardly, spreading the toggles. The end bars at one end o'f th-e cot are then swung outwardly, and the latch bolts automatically lock with the legs, the beveled ends 7 of the bolts sliding'over the ends of thecentral bars and into the slots in the legs. The end bars at the opposite end of the cot are then swung outwardly, but not into the locking position, and the fabric frame is then hooked over the end bars; After the fabric frame has been applied,the' end barswhich were last un- "folded, are pressed downwardly and the bolts the'adj acent legs.

' To fold the'cot, the operation is reversed,

thereon automatically enter the openings in the bolts at one end of the cot being first released, afterwhich the fabric frame may be unhooked. Ihe end bars, after releasing the bolts, may then be folded over the backs of the central bars, and the legs may be folded within the centralbars after the toggles havebeen broken and the legs at the opposite sides' of the cot have been brought together, as shown in Fig. 6.
