Abstract: The foldable bed has a frame including pairs of upper and lower U-shaped supporting tubes, each pair forming a substantially rectangular structure for fixing a cloth forming the side wall of the bed. The supporting tubes are pivotably connected with and supported by two U-shaped legs. The upper supporting tubes and the legs are interconnected by struts locking the upper supporting tubes in a horizontal position when the bed is in its open state for use. The connection between each strut and the adjacent leg is made by means of a sliding member slidable along a side-piece of the leg. This slidable connection between each strut and the adjacent leg substantially facilitates folding and opening the bed and minimizes the danger of hurting the user or a child in the bed.

Abstract: A double joint assembly for interconnecting three elements of a foldable structure, two elements being capable of pivoting in the same plane so as to be located at a pre-selected angle to the third element, the joint assembly comprising a forked member, a clamping member and a bolt member, each of which members is integral with, or affixable to one of the said elements, the clamping member and the bolt member each having a flat portion which is pivotable about a pivot axis and which is located in an aperture formed in the forked member, each flat portion having a cam surface formed thereon having at least one support surface, that the clamping member abuts against one surface of the forked member when the foldable structure is extended, the cam surface of the bolt member co-operating with the cam surface of the clamping member such that, in use, the clamping member is retained in position relative to the forked member in two directions, the angular position of the bolt member being determined by the angle at
