ABSTRACT:
A locking pivot member for mounting on a first member and which releasably holds a second member in a coupled pivotal relation thereto. The locking pivot includes a generally cylindrical body portion which is elongated along an axis from a free end portion to a mounted end portion which is secured to the first member. The cylindrical body is further provided with a radially and inwardly extending peripheral groove at a distance spaced axially towards the free end portion and from the first member. A continuous O-ring made of plastic rubber, teflon or other resiliently deformable material is positioned in the peripheral groove. The O-ring is formed having an inner diameter approximately equal to that of the innermost diameter of the radial groove, and an outer diameter greater than that of the remainder of the cylindrical body. The pivot is inserted through an opening in the second member which has a diameter marginally greater than the diameter of the cylindrical body, but which is less than the outermost diameter of the O-ring. When coupled, the cylindrical body extends through the opening so that the second member is pivotable about the axis of the pivot but which is retained against withdrawal by engagement with the O-ring.
