ABSTRACT:
Apparatus comprising a first member including first and second member engagement surfaces, a second member, a pin pivotally connecting the first and second members, the pin having a longitudinal axis and opposite ends, and a retainer for retaining the pin in position relative to the first and second members, the retainer having a center of gravity and including first and second retainer engagement surfaces, the retainer being movable relative to the first member between a retaining position and a non-retaining position so that, when the retainer is in the retaining position, the first and second member engagement surfaces respectively engage the first and second retainer engagement surfaces to limit axial movement of the retainer relative to the first member, the retainer covers one end of the pin and thereby limits axial movement of the pin relative to the first member, the retainer has a point of engagement with the first member, and the position of the center of gravity relative to the point of engagement is such that gravity biases the retainer in a direction so that the retainer remains substantially in the retaining position, whereby the retainer is held in the retaining position without welds or other locking mechanisms, and so that, when the retainer is in the non-retaining position, the first and second member surfaces are out of engagement with the first and second retainer surfaces such that the retainer is removable from the first member.
