A carry-cot is collapsible from an open use state into a flat state. For this purpose the cot has an upper frame and a lower frame, with a flexible sheet stretched between these two frames to form an all-around side wall. A bottom plate is placed on the lower frame. The upper and lower frames are connected by four foldable links. As these links are collapsed or folded, the upper frame approaches the lower frame until the flat collapsed state is established. A first belt is attached at its ends to the first and second link and a second belt is attached at its ends to the third and fourth link means for carrying the cot.

In a box-type carry-cot having a box frame with an open top and flexible belt means (1, 2) having opposed ends connected to frame points located to surround the center of gravity of the carry-cot, so that the carry-cot can be suspended by lifting the belts, the improvement comprising an upper frame (3) forming a peripheral edge defining said open top, a lower base (4) forming a peripheral edge and disposed parallel to and below said upper frame (3) and defining a bottom wall of the carry-cot, flexible sheet means (5) stretched between said upper frame (3) and the peripheral edge of said lower base (4) for forming box side walls, a head wall and a foot wall, first, second, third and fourth link means (6, 7, 8, 9) arranged in pairs for holding said upper frame (3) and said lower base (4) so as to allow them to move toward and away from each other, each link means comprising a main support rod (14) having upper and lower ends, and an auxiliary support rod (15) also having upper and lower ends first journal means (16) for connecting said lower end of said auxiliary support rod to a lengthwise intermediate portion of said main support rod (14) so that said rods can overlap each other when the rods extend longitudinally in parallel with each other, said first and second link means (6, 7) being disposed on one side of said cot and said third and fourth link means (8, 9) being disposed on the other side of the said cot, second journal means (18) for connecting said lower ends of said individual main support rods to an outer periphery of said lower base (4) at four points surrounding the center of gravity of the carry-cot, third journal means (35) for individually connecting said upper ends of said auxiliary support rods (15) to an outer peripheral edge of said upper frame (3) so that when said individual link means (6 to 9) are respectively in the linear state, the first and second link means (6, 7) on the one hand and the third and fourth link means on the other hand are directed obliquely upwardly with their upper ends positioned closer to each other than their respective lower ends, first folding stop means (17) enabling said first and second link means (6, 7) and said third and fourth link means (8, 9) to collapse from their respective linear states only in one direction (A) in which said upper ends of said main and auxiliary support rods (14, 15) move away from each other, second folding stop means (32, 33) for limiting the cot opening movement of said individual link means when they are respectively in the linear state and for maintaining said upper frame (3) and said lower base (4) at a maximum distance from each other and substantially parallel to each other, whereby said main support rods (14) of each pair are prevented from further rotating in the direction in which they approach each other, locking means (23) for elastically engaging said main and auxiliary support rods (14, 15) of a pair with each other to maintain the main and auxiliary rods in the linear state, wherein said belt means include a first belt (1) attached with its ends to the lower ends of said main support rods of said first and second link means (6, 7) and a second belt (2) attached with its ends to the lower ends of said main support rods of said third and fourth link means (8, 9), and wherein each of said main support rods (14) comprises belt guide means (27) defining a belt receiving hole (26) substantially at the upper end of the respective main support rod, said first and second belts (1, 2) being inserted in the respective belt receiving hole for maintaining the respective belt end substantially alongside the respective main support rod.
