摘要

One-piece reinsured foldable advertising chair, characterized in particular by obtaining it from a piece of cut or cut material (drawing 1), which has different flaps or zones, separated by creases, of which the two upper centrals (j and k) are of greater height than the rest of them and that when extending along the central axis of height and superimposing the bases symmetrically one of the flaps protrudes (I), which is folded outwards to serve as a link together with the flap h to shelter inside the flap a, which for its connection will be linked by the tab 6 and its slot of the same name (6 "'') in the lower part of the same flap and link in the three flaps a, h and i, giving us a set of three layers of material in its vertical position with a triple development of pressure and weight support.when this unión is achieved, we take it to the central axis and develop the seating position (l) and backrest ( m and ll) proceeding by means of the crimping system by inserting the tab l "'' in the closing groove 4, designed in the flap c as an entry and without possibility of exit, raising the wings once the closure has been inserted in its hole in the shape of "U" inverted. For the backing we proceed in the same way with the flaps n ll and the flange n. The latter is inserted in the crimp slot k "'' of the flap k, making a downward stroke as a bolt that, with the assembly already made, and placed the structure in a horizontal plane, performs a force of no return back, getting in third safe.after developed the entire structure and fixed the three aforementioned insurance, we proceed to the assembly of stable seating position with the closure l "'', automatically achieving that the seat (flap l), just on its central side, fastens, by downward pressure, a non-return closure with projections 1 and 5 and slot 4, which supports the weight capacity and pressure of the spine at the point of the coccyx of a human body.
