ABSTRACT:
A pivoting joint assembly that includes a first portion formed with a first aperture and a second portion formed with a second aperture, the first and second apertures being alignable. A recess is formed about the second aperture. There is a shaft insertable through the first and second apertures. A bearing surface is formed adjacent one end of the shaft and a retaining member is releasably mountable to the other end of the shaft. A spacing member is insertable between the first and second portions to separate the portions to an extent such that the bearing surface of the shaft engages and retains the first portion on the shaft and the retaining member mounted to the shaft is positioned within the recess of the second portion to define a second bearing surface that engages and retains the second portion on the shaft. The first and second portions are releasably and rotatably locked together for rotation with respect to each other about an axis defined by the shaft.
