Abstract:
1. A washer incorporated into a pivot assembly including a support sector and a rotatable sector pivotally mounted to the support sector by aligning apertures in the sectors which receive a widthwise inserting pin, said washer comprising: a disk shaped body defining an open interior and supported by the pin between the sectors; and first and second pluralities of protrusions extending from each of first and second annular faces of said body and which are arranged in either of circumferentially or radially offset and uneven grouped fashion, said protrusions exhibiting deformable characteristics which, upon application of laterally compressive forces associated with assembling the sectors, results in collapsing of said protrusions in order to reduce instances of lateral play between the sectors and body while allowing for variations in material thickness between the sectors.
