<p>A telescopic handling arm comprises a module consisting of two segments (12, 14) and a knee cap (15). All the motions of the knee cap (15) are transmitted through the module by similar mechanisms so that the frictions and inertia are the same for each motion. Said mechanisms comprise shafts (36a-36c) housed at equal distance from the axis XX' in the lower segment (14) and shafts (56a-56c) housed at equal distance from the axis XX' in the upper segment (12). The shafts (36a-36c) carry similar pinions (40a-40c) which are in mesh with similar toothed wheels (42a-42c) which are also in mesh with identical pinions (46a-46c) integrally rotated by the shafts (56a-56c).</p> |
