ABSTRACT:
A spring pivot joint comprises two face plates with heavy serrations or ribs between them, both sandwiched between Belville springs or spring washers, the washers being held in a strongly stressed condition by a hollow rivet. The face plates have integral wings or tabs extending radially beyond the washers for attachment to the companion mannequin parts to be jointed. Since the rivets are hollow, a simple rod can extend through a plurality of them to hold them in coaxial alignment while being attached to the jointed mannequin parts.
