Pivoting joint assembly

A pivoting joint assembly comprising:

• a first portion formed with a first aperture;
• a second portion formed with a second aperture, said first and second apertures being alignable;
• a recess formed about the second aperture;
• a shaft insertable through the first and second apertures;
• bearing means formed formed adjacent one end of the shaft;
• a retaining member releasably mountable to the other end of the shaft to prevent axial movement of the retaining member alone the shaft;
• a spacing member comprising an annular split ring having two parts insertable between the first and second portions about the shaft, and locking means to hold the two parts together when in position about the shaft, the spacing member acting to separate the portions to an extent such that the bearing means 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 means that engages and retains the second portion on the shaft to releasably and rotatably lock together the first and second portions for rotation with respect to each other about an axis defined by the shaft.
