摘要

Improved ball joint device for supporting or similar structures, of the type constituted by a main body (1) adopting an approximately parallelepipedic shape formed by two front faces (1a) and rear (1b) square with blunt vertexes and four lateral faces ( 1c) rectangular, rounded edges; wherein said main body (1), has on its lateral (1c) and rear (1b) sides, alternately, two cubic niches (2) suitable for housing and fixing, by conventional means such as screw threading through of the holes (3), allowing the articulation or pivoting in a range of up to 90º of the tubular elements that will make up the structure to which it is intended characterized by the fact of comprising the main body (1), on the front face (1a ) axially a through hole (4) able to receive the tie element (5), which consists of an elongated cylindrical piece (5a) provided at its end with a frustoconical head (5b), axially associated therewith by means of a small stem (5c), to which a groove (5d) has been made to give it a certain elasticity that will allow its introduction and fixation in said through hole (4), thus acting as an element of association and positioning between conjugate nodular numbers or between one of them and a fixed base.
