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. Another assenblies element according to the invention is a containing body of substantially tray shape, equipped at the end with a folded edge suitable to be inserted and housed in the longitudinal groove of the crosspiece. The above elements are equipped with ribs and/or folded and/or superposed stiffening parts to increase their flexural strength.

Dependent claims

An assemblable modular structure in thin sheet comprising at least two front and two rear uprights (46), at least two crosspieces (10) engageable with said uprights, one crosspiece extending between said two front uprights and one crosspiece extending between said two rear uprights, a spacer (32) extending between one front and a rear upright and engageable therewith, a horizontal shelf (24) having squashed and folded end sides (30) and a tray (38) having folded edges (44), said shelf and said tray being engageable with said crosspieces, each of said uprights having a square cross section and four faces and each said face having a central longitudinal rib (19) and first projections (60) essentially of mushroom shape on each face, each projection being formed by a round head (60a) and a shank (60b), said crosspiece (10) being formed by an essentially tubular box-shaped body having an upper face (12), a lower face (14) a front face (18) and a rear face (18'), said upper face (12) having a groove (16) capable of seating said squashed and folded end sides (30) of said supporting shelf (24) and said folded edges (44) of said tray (38), said crosspiece (10) presenting strengthening second projections (20) on said front face, said second projections having first openings (22), said first projections (60) of each of said uprights engaging with said first openings (22) in said crosspiece, said spacer (32) having second openings (72) at the ends thereof, said first projections (60) of the upright (46) being inserted in said second openings to fix the spacing at the ends of said spacer (32).
