Abstract: A folding chassis (1) for a child's pushchair comprising a plurality of up members (10, 11, 13, 13) for supporting the wheels and a support for the child, in which at least two members (10, 11, 13, 13) of said plurality of members are articulated to one another in such a way that when the chassis is in a deployed configuration the angular separation between these two members is higher than it is when the chassis is in a folded configuration, and in which each one of said two members comprises several parts (1021, 1022, 1121, 1122, 121, 122, 131, 132) able to slide relative to one another in a longitudinal direction of said member.

Abstract: A shelving system includes first and second support members extending in parallel vertical planes, and a pair of shelves mounted intermediate the support members. Each of the shelves has a longitudinal pivot axis perpendicular to the planes of the support members. Each shelf is continuously positionable at any angular orientation about its pivot axis. Each of the support members includes an upper and a lower stacking surface. Modular units may be stacked to form a larger shelving system wherein mating upper and lower stacking surfaces abut. To facilitate alignment when stacked, the stacking surfaces include first and second alignment portions, and upper and lower alignment cavities formed in each support member. To maintain alignment of the units, an alignment member is received in mutually facing alignment cavities in the assembled shelving system.
