Abstract

In a universal (three axis) joint for a tool plate 10 of the manipulator mechanisms of automatic handling equipment, there are two third members (23a, 23b) each pivotally supported by a second member (22), and wherein each third member (23a, 23b) a) is essentially U-shaped, having a base portion with two free edges upstanding therefrom between which extends a third axis (C-C), b) carries thrust member attachment means located upon the face of the base portion opposing the free ends and nearer one such end than the other, whereby there may be affixed thereto a thrust member (24a, 24b), and c) is supported about the third axis (C-C) with its free ends interleaved with those of the other third member, so that the two attachment means (and, when affixed thereto, the two thrust members) are coplanar with first (A-A) and second (B-B) axes, and any forces transmitted therethrough intersect with the three axis intersection point. A U-shaped first member 21 is pivotally supported upon the tool plate 10 by a spindle 31. <IMAGE>
