ABSTRACT:
A friction detent apparatus includes a resistance washer having a planar circular body with a central portion fixedly mounted to a pivot rod attached to a support structure, the body having a first arcuate friction contact surface spaced a first predetermined distance from the central portion and a second arcuate friction contact surface spaced a second greater predetermined distance from the central portion, a first detent nub formed on the first contact surface and a second detent nub formed on the second contact surface. First and second follower pins are fixedly mounted on a device pivotally mounted on the pivot rod for engaging the first and second friction surfaces respectively. The pins move along the friction surfaces as the device is rotated relative to the pivot rod and the detent nubs releasably retain the pins in an "end of travel" position. In a tension beam washer form, an elongated arcuate slot in the body has the first friction surface as a side thereof and a portion of the body is deflected outwardly under tension as the first pin moves past the first detent nub. In a compression beam washer form, the first friction surface is formed as a radially recessed portion of a periphery of the body, an arcuate slot is formed in the body and the portion of the body adjacent the slot is deflected inwardly under compression as the first pin moves past the first detent nub.
