摘要

A tumbler pin tip and key surface are configured so that when engaged, the tumbler pin tip fully and precisely seats in the key bitting, and thus is rotationally positioned at a predetermined location. The contacting surfaces are generally sloped from one edge of the tumbler (and key surface) to the other in tapered form and the sloping surface may be flat, concave, convex or a combination as disclosed.
