Abstract: The two ends of the girders used for the formation of modular shelves are provided with a pair of superposed fasteners wherein the inlet and outlet eyelets which circumscribe the passage slits of the fasteners, are exactly equal and coaxial with each other. The pair of fasteners, which are located near the corners of the ends of the girders, engage in restrained relation and correct vertical alignment with as many superposed indentations formed along vertical uprights of the modular shelves. The indentations and pair of fasteners have the same distance between centres and combine with each other, in stable and aligned restrained coupling, because of the equal and coaxial configuration of the sections of the passage slits of the fasteners.

Abstract: Assemblable modular elements are described, particularly in thin sheet, suitable for the formation of a metal shelving. The modular elements in question essentially comprise substantially tubular box-shaped bodies of generally rectilinear shape, which, on their upper face, are equipped with a longitudinal groove suitable to receive the folded or squashed end side of further elements forming supporting shelves. Said box-shaped bodies are also equipped, on their projecting portions, with openings suitable to receive corresponding projecting portions of further substantially rectilinear tubular elements forming the uprights of the shelving.A substantially elongated, rectilinear element equipped at the ends with at least one opening suitable to receive the projecting portions of the uprights, forming in this way a spacer of the shelving, also forms the object of the invention.

Abstract: Simplified metallic structures, in particular shelving, consisting of shelves and uprights, made of relatively thin sheet metal and complete with projections and of fixing members consisting of plastic angular components arranged in the space defined between the uprights and the shelves and with cavities where the projections of the shelves and the uprights are inserted.The uprights may have the same shape and dimensions of the shelves, or may have smaller dimensions and have a transverse section corresponding to that of the cavity. A hole is made in the angular components where the fixing and anchoring tie-rods are inserted.
