Component for shelf units, shelves, bookcases, stairs and similar furnishing elements and its manufacturing process

A process for making a component for shelving, shelves, bookcases, stairs and similar furnishing elements comprising the steps which consist of:

• extruding metal crosspieces having snap fitting means for their reciprocal connection and at least one elongate element made of metal material;
• milling said at least one elongate element along a longitudinal direction of extension of said at least one elongate element, in such a way as to form an inner groove designed to house induction lighting means and so that said inner groove has a substantially elliptical curvilinear profile shaped in such a way as to hide the light source of said lighting means from direct contact with the eye of the user;
• making ducts for the passage of cables for electrifying said lighting means on said metal crosspieces, in such a way as to allow the mutual communication between each of said inner grooves with the corresponding said conduits;
• connecting said metal crosspieces using said snap fitting means to form a frame defining a perimeter;
• positioning, inside said perimeter, at least one elongate element and a reinforcement plate, one adjacent to the other in such a way as to form an intermediate layer defining a plane of extension of the component;
• said at least one elongate element housing said lighting means in said inner groove and said reinforcing plate having a structure consisting of a tessellation of the space of the honeycomb type, preferably honeycomb-shaped;
• said intermediate layer interposing at least two laminar elements substantially parallel to each other;
• passing said cables in said ducts in such a way as to be able to connect them to said lighting means;
• making, by removing material, a window on a first element of said at least two laminar elements;
• said window being defined at said inner groove, in such a way that the light emitted by said lighting means is not stopped by the thickness of said first element (2′);
• and
• gluing said laminar elements to opposite faces of said intermediate layer in such a way as to make the component.
