PATENTEDO0I24 m2 SHEET 6 [IF 6 FOLDING BED This invention relates to folding beds.

Known folding beds have certain drawbacks, notably mechanical complexity, inaestheticappearance of the folded bed and, when portable, the necessity of transporting the bedding separately from the folded bed.

It is an object of the invention to provide a folding bed of simple construction portable together with the bedding, and of an agreeable aesthetic appearance both when folded and open. Such a bed is principally intended as a childs cot, but this use is not limiting.

Accordingly, the invention provides a foldable bed comprising two half-shells foldable together to form a valise, handle means to enable carrying of said valise, said half-shells each being provided with foldable frame members retractable into said valise when closed and adapted to open into frame members for the bed when open, foldable feet members on each of said half shells, and means for locking said feet in operative position.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

FIGS. 1 to 4 are perspective views of a first embodiment with the bed in erected, partially folded, folded flat, and stored positions respectively;

FIG. is an enlarged perspective view of a lock plate of the first embodiment;

FIGS. 6 and 7 are perspective views of second and third embodiments;

FIG. 8 is a perspective view of the fourth embodiment during folding thereof;

FIGS. 9, 10, 11 and 12 are perspective views of fifth, sixth, seventh and eighth embodiments; and

FIG. 13 is a side view of the eighth embodiment during folding thereof.

Referring to FIGS. 1 to 5, the first embodiment of the invention comprises two rigid half-shells 1 and 2, for example of a synthetic material, and of a shape corresponding to the two parts of a valise. The half-shells could, alternatively, be in a supple material, for example a fabric, on a rigid frame. Half-shells 1 and 2 are pivotally joined to a rigid panel 5 by means of hinges 3 and 4 respectively. Panel 5 is of slightly less width than half-shells l and 2 and is provided at its two ends with rigid plates 6 and 7 which fit inside the half-shells when closed.

Each half-shell has a foot member, 8 and 9 respectively, formed of a bent tube. The feet members are pivoted about axes l0 and 11, 12 and 13 on the lateral walls of half-shells 1 and 2. Of course, instead of using two feet members each from a single tube, four independent feet could be provided.

Each half-shell 1 and 2 is additionally provided with an end frame member 18, 19 respectively articulated to the half-shells at 14, and 16, 17. The end frames are connected to the extremities of the feet members by ,60

Referring to FIG. 5, the side frames, for example and 27 as illustrated, can be locked together with plate 7. For this purpose, the top of plate 7 is provided with two inwardly directed channels 70: and 7b separated by an opening 28. Channels 7a and 7b are adapted to receive horizontal tubes 25c and 270 respectively whilst vertical tubes 25d and 27d lie together, tubes 25 and 27 passing through opening 28. Below opening 28, a cam 29 is pivotally fixed at 30 on plate 7 and is rotatable by means of a button, not shown, on the outside of plate 7. The cam, for example of synthetic material, is partially of circular shape and has a flat 31 so that when the button is turned so that flat 31 faces opening 28, tubes 25c and 27c can be pushed down and removed from or inserted in channels 7a and 7b. When tubes 25c and 270 are thus placed in the channels 7a and 7b the button can be turned so thatthe circular cam surface presses tubes 25c and 27c against the channels 7 a and 7b thereby positionally locking the side and end frame members and, additionally, feet members 8 and 9. Sideframe members 24 and 26 are similarly locked so that the cot can be simply and rapidly locked in its open position.

Of course, other locking devices are possible and could act on the side or end frame members, on the feet members, or on the half-shells 1 and 2, or be a combination of any of these means.

The operation of folding up the cot can easily be understood by considering FIGS. 1, 2, 3 and 4 in turn. Firstly the locking devices, such as described with reference to FIG. 5, are unlocked and side frame members 24, 25 and 26, 27 are folded adjacent to their respective end frame members 18 and 19 as shown in FIG. 2. End frame members 18 and 19 are then folded flat onto half-shells l and 2 as shown in FIG. 3. The two half-shells are then folded together to form a valise and are locked with a standard releasable fastener 33, as shown in FIG. 4. This latter operation brings feet mem bers 8 and 9 adjacent one another so that they form a handle suitable for carrying the valise.

The bedding 32 is schematically shown on FIG. 1 and is not shown on FIGS. 2 and 3. However, it is understood that the bedding can remain in the cot during the folding and unfolding operations so that the cot, folded into a valise, can be carried with the bedding protected both from the weather and from the possibility of soiling.

Referring now to FIG. 6, there'is shown a cot formed from two half-shells 41 and 42 foldable about a central panel 43. Feet members 44 and 45 are pivoted on halfshells 41 and 42 and are connected to foldable endframe members 46 and 47 by pivoted arms 48 and 49 respectively. Two pairs of identical side-frame members 50 are each pivotally attached to hinge members 51 and 52 which are solidly fixed perpendicularly to the ends of panel 43.

When the cot is opened out, the free ends of side frame members 50 are attached by any suitable means to the uprights of end frames 46 and 47, thereby locking the cot in its erected position. To store away the cot, the side frame members 50 are pivoted to their central position, as indicated by arrows A, the end frame members 46 and 47 are then folded flat onto the half-shells 41 and 42, and the two half-shells are folded together, as for the first embodiment.

Referring to FIGS. 7 and 8, for this embodiment the end frame members 46 and 47 and four side frame members 53 are all pivoted about horizontal hinge members on the corresponding edges of the half-shells 41 and 42. The central panel 43 has two vertical uprights 54 provided with means 55 which enable locking of the side frame members. Clips 56 are additionally provided on the end frame members 46 and 47 to enable clipping of side frame members 53 thereon.

Feet members 57 and 58 are pivotable about the same axes as end frame members 46 and 47 and advantageously are rigidly connected to their end frame member. Of course, the same system of positioning the feet could be used with other arrangements for the side frame members.

Referring to FIG. 9, two half-shells 59 and 60 are pivotally joined to a central panel (not shown) carrying two uprights 61. Two U-shaped tubular frame members 62 and 63 are pivotally fixed, at their ends, to the uprights 61. On the side arms 62a and 63a of the frame members are provided slidable runners 64 and 65. Feet members '66 and 67 are pivoted to the half-shells at 68 and 69 respectively and to the runners 64 and 65. Therefore, raising or lowering frame member 62 causes raising orlowering of foot member 66 and similarly for frame member 63 and foot member 67. Nicks 70 and 71- are provided in the walls of the half-shells to enable passage, when the half-shells are folded, of the join of the feet members with the runners and the tubular frame members 62 and 63.

A skirt 72, for example in a canvas fabric, is carried by frame members 62 and 63 and uprights 61, the skirt forming the walls of the cot when erected.

The embodiment illustrated in FIG. comprises two half-shells 73 and 74 connected to one another by lateral expansible frames 75 and 76 comprising a plurality of articulated arms. A half-mattress is foldable into each half-shell, only one half-mattress 77 with a rigid base 79 being shown. Cross beams 80 are attached to each intermediate lower articulations 80a and 80b of the pairs of arms. Feet 81 are capable of sliding into the half-shells and are connected to the articulated arms in such a way that approaching the two half-shells together causes entry of the feet whilst separation of the half-shells causes protrusion thereof. Suitably, for this purpose the feet are mechanically linked to the upper extremities of the end arms which are free to move vertically in the half-shells, the lower extremities of the end arms being fixed. Preferably, frames 75 and 76 are covered with a canvas fabric 82. 5

FIG. 1 1 shows a variation of the embodiment of FIG. 10, in which the half-shells 73 and 74 are joined by deformable lateral frames covered with a canvas fabric 83. The half-shells are shown at an intermediate position (73a, 74a) in dotted-dashed lines, where the intermediate positions of articulated pairs of arms 84 (84a and 84b, 84c and 84d) are also seen. The arms 84a and 84b, 84c and 84d can be of different lengths.

Feet 96 are retractable in any suitable manner into the half shells and are provided with locking means (not shown) to fix them in the open position. Two halfmattresses 86 can be stored in the half-shells and can be folded down onto the base of the bed to lock it in open position.

The bed shown in FIGS. 12 and 13 has one half-shell 87 forming the body of the valise, the other halfshell 88 articulated on half-shell 87, forming a cover. The cover 87 supports, in the open position a part of mattress 89, the other part of which is supported by a base member 90 pivotally mounted to the edge 88a of the cover. Base member 90 also has a foldable frame member 91 and feet 92. A locking device 93 is provided for frame member 91. A foldable foot member 94 is provided on base member 90 to support the mid dle part of the bed, whilst foot member 95 fixed to the body 87 can be used to carry the folded bed.
