ABSTRACT:
The invention provides a dismantleable ball and socket joint.
A bearing made of a plastic material is placed in a rigid housing, and is adapted to receive a ball. Accessory component parts, or special shaping of the bearing provide elasticity to the bearing, which enables part of the bearing to change position relative to the housing, according to the direction of insertion or extraction of the ball. On assembly, the bearing contracts and expands.
The assembly of the ball and socket joint requires a much smaller force than that required for extraction of the ball from the socket.
