Abstract (en)
[origin: EP0053582A1] 1. Joint for spatial framework structures in geometric module with pyramidal base and tetrahedral (fig.1) in which converge same shafts endowed with spheres at the tips directed in every direction in the space, it is composed of two parts jointed together by one central bolt, it is caracterized by two caps of changeable thickness, semispheric and hollow, in which converge twelve shafts (7) (fig. 3) endowed with one sphere (9) through one pipe (8), four horizontal and eight oblique, they are characterized by four large slits (4) orthogonal to each other, to allow the introduction of the spheric terminals of the oblique shafts, and characterized by four semicircular holes (5) to allow the introduction of spheric terminals of the four horizontal shafts, so that the central bolt (1) that cross the hole of the cap is tangent to the spheres of the shafts and at the same time all the spheres are tangent to the hemispheric inside surface of the two caps when these caps are assembled with the introduction of the terminal of the shafts in the slits (4) and (5), allowing their rotation in every direction in the space after the blockage.
