ABSTRACT:
A swivel assembly comprises a housing having a bore extending therethrough along a central axis. The housing has an end wall with an opening about the axis extending therethrough. A generally spherical swivel member is rotatably and swivelly disposed in the bore and includes an extension protruding through the opening. The portion of the extension within the opening is substantially smaller in transverse cross-section than the opening to permit limited swivel movement of the swivel member in the housing. The bore has first and second sections. The first section has a smaller diameter than the second section and thereby forms a wall. A stiff resilient element is provided between the wall and the swivel member for preventing movement of the spherical swivel member when subjected to a heavy load.
