ABSTRACT:
The invention is a mechanism for selectively fixing the angular relationship of two pivotaly related structural members in finite steps using a manually actuated, cam-activated gear lock. This provides an adjustable and selectively lockable angular relationship. Fixed and moveable cylindrical cams and a concentric face gear/clutch are used. In one application, the mechanism is incorporated into a four bar linkage.
