Patented Apr. 13, 1937 abuses PATENT or ies FOLDING COT FOR CHILDREN Thodore Bonny, Chambesy-Geneva, Switzerland Application January 6, 1936, Serial No. 57,859 In France January 16, 1935 2 Claims.

The object of the invention is a folding cot for children.

The cot comprises a framework constructed of wood, metal tubes or light metal bars, the parts of which are so connected together that the whole is easy to fold to an easily transportable and noncumbersome form, and can be unfolded to form a rigid structure when required for use.

The annexed drawing illustrates a form of construction of the cot according to my invention.

The cot comprises four groups of similar ele ments: and since these groups are alike details of one only are illustrated.

Fig. 1 is a diagrammatic view of a bed according to the present invention.

Figs. 2, 3 and 5 are partial views in elevation.

Fig. 4 is a plan of the middle portion of the framework.

Fig. 6 is a sectional elevation drawn to a larger scale of a detail of construction.

Fig. '7 is a plan view of Fig. 6.

Fig. 8 shows the position of elements after partial folding.

Fig. 9 is a complete view of the folded device before securing with a girth or strap with tightening buckle.

i Fig. 10'illustrates a method of connecting one of the corners of a flexible sheet for example of canvas, to the framework.

Fig. 11 is a sectional view of a hem on the edges of said sheet giving the stiffness of four thicknesses of fabric.

Figs. 12, 13 and 14 are detail views illustrating a modification of construction.

In the position of use each corner of the sheet I is provided with a reinforced opening laby means of which the sheet is hooked to a stud l on the upper end of an upright 2 articulated to two struts 4, 5 themselves articulated on one of the 40 four arms 6 of a cross-bar, said arms being articulated on the ribs of a central plate N) (Fig. 4).

; Each of the four legs I is articulated by means of fish plates 8 to one of the arms 6 and can be folded as indicated in dotted lines in Fig. 2, which 4.5 allows for a low position of the cot, the thickness only of the legs I being then interposed between the ground and the arms 6.

Supports 3 can be easily secured to the uprights 2 and are intended to eventually maintain a fabric vertically round the sheet I such as a mosuito-net.

The connection of the various parts is obtained by connections comprising headed studs 2 each engaging in the circular portion of a keyhole slot 6 so as to allow the head to pass through, which is then slid into the narrow portion whereit is maintained against removal. The drawing illustrates this means of fixing, well known for other uses.

Hooking of the sheet l to rings 9 is available 5 for accentuating the tension of the sheet.

A sliding stirrup H enables the device to be easily gripped when dismounting or mounting.

The various parts can be articulated together, in slightly difierent ways according to the cases, in particular according to the size of said parts, they may comprise spring abutments or the like.

On the sheet I can be placed a mattress the under side of which would have the curve of said cloth, the top side being practically fiat, and 15 the said mattress can be held at its corners by hooking buckles.

In the folded position the four groups of elements of the framework are placed near each other as indicated in Fig. 9. A girth or a strap will enable them to be kept in a bundle, together with the cloth rolled up into small volume.

The hem in four thicknesses, Fig. 11, tensions the edges of the sheet I and the hollow thus formed by the latter, also accentuated by the 25 weight supported forms for the child a surface which gives under the weight of the child which tends to prevent it from falling out.

Figs. 12 to 14 show a modification, each support 3 is provided with a hook-shaped metal plate 2 l, intended to be hooked on a support 52 passing through a housing l3 provided in the upright 2. At I4 is a recess for the upper flange of a fillet, which flange is retained by a plate-spring iii. The plate-spring l6 opposes any accidental collapse up of the leg 1. A knob ll enters a hole of H5, in the same way as a knob it enters the hole ill of the blade 26.

I claim;

1. A folding cot comprising a central ribbed plate, a group of arms pivoted at one end to said plate and adapted in operative position to project horizontally outwardly from said central plate, a leg pivotally mounted on the outer end of each arm for movement from a folded position parallel to and in contact with its associated arm to a use position substantially perpendicular to said arm, an upright member associated with .each arm, each upright member having its lower end detachably connected to the outer end of the associated arm, stays pivotally connected between said arms and associated upright mem-- bers to maintain the latter in an upright position, and a sheet of fabric detachably connected to the tops of said upright members, said arms,

legs and upright members being adapted to be swung about their pivots to occupy positions parallel to each other when folded.

2. A folding cot comprising a central ribbed plate, a group of arms pivoted at one end to said plate and adapted in operative position to project horizontally outwardly from said central plate, a leg pivotally mounted on the outer end of each arm for movement from a folded position parallel to and in contact with its associated arm to a use position substantially perpendicular to said arm, the upper surface of each arm having a recess formed therein adjacent the outer end thereof, a plate having a keyhole slot therein covering said recess, and positioned with the circular portion of the keyhole slot inwardly, an upright member associated with each arm, a stud having an enlarged head on the lower end of each upright member for cooperating with said keyhole slot to detachably connect said upright member to its associated arm, stays pivotally connected between said arms and associated upright members to maintain the latter in an upright position, and a sheet of fabric detachably connected to the tops of said upright members, said arms, legs and upright members being adapted to be swung about their pivots to occupy positions parallel to each other when folded.

THEODORE BONNY.
