Abstract
A washer formed by two identical C-shaped sections having parallel upper and lower surfaces, two ends, an inside and an outside arcuate edge, the ends having a plurality of tabs and recesses that inter-digitate to form continuous surfaces. The outside arcuate edges have a slot adjacent to one end and a flap projecting from the opposite end. The flaps are inserted into the slots of adjacent sections to retain adjoining ends in fixed relation to each other. Additional grooves on the outside arcuate edge facilitate assembly using needle-nosed pliers.
Claims12
A washer comprising:
- two identical C-shaped sections, each section having parallel upper and lower surfaces and a perimeter comprising two ends, an unthreaded inside arcuate edge and a substantially smooth outside arcuate edge, and a plurality of tabs projecting from the ends and separated from each other by intervening recesses configured so that the tabs and recesses of adjoining ends of the two sections can inter-digitate to form a substantially continuous surface, the tabs and recesses being configured so that the inter-digitation is achieved without requiring any change in the thickness of the washer, the smoothly smooth outside arcuate edge including a groove adjacent to each end for receiving an installing tool to facilitate inter-digitation of the tabs and recesses, the groove extending through the upper and lower surfaces of the section.
A C-shaped molded polymeric washer section comprising:
- parallel upper and lower surfaces and a perimeter comprising two ends, an unthreaded inside arcuate edge and a substantially smooth outside arcuate edge, a plurality of tabs projecting from the ends, the tabs being separated by intervening recesses sized and shaped to receive corresponding tabs projecting from an end of an identically shaped C-shaped washer section, the substantially smooth outside arcuate edge including a groove adjacent each end adapted to receive a washer installing tool facilitating inter-digitation of the tabs and recesses of each end with an adjacently positioned end of the identically shaped C-shaped washer section, the groove extending through the upper and lower surfaces of the washer section.
