摘要

Method of attaching metal frames or similar and the framework required to execute said procedure; for the construction of furniture, shelves, scaffolding and the like for disassembling, the frame being characterized as being rectangular with elastic material (Figures 1, 2 and 3) arranged to be hooked in different ways to other similar frames, whose frame is essentially composed of following elements: a) two first cylindrical bars in the shape of "U" (1a, 2a, 3a or 4a), of which the greater arm forms one of the respective minor sides of said frame; b) two parallel beams, which form the major sides of said frame, each of which is constituted by two second straight cylindrical bars, of a diameter equal to that of the aforementioned "U" bars, joined together by suitable means to said "U" bars (1b, 2b or 3b); c) eight semi-cylindrical notches, of the same diameter of the second straight bars forming said beams whose notches are located at the inner end of said second bars, and whose axes of symmetry are perpendicular to the plane of the frame (1c); d) a series of tabs, integral with said second bars and formed from their same body, located at equal intervals from the ends of said second bars and in the line of intersection of the lateral surface of each bar with a diametrical plane parallel to the plane of the frame; e) four stops (1e and 2e) placed between said second bars forming said beams, joined together thereto, and in contact and only in contact with said first "U" bars; f) a third straight bar (1f and 2f), cylindrical, parallel and equidistant to said greater arms of said first "U" bars, so that it divides the frame into two equal parts, solidly joined to said second bars forming said beams and between which it is imprisoned.
