ABSTRACT:
An axial split-pin tumbler-type lock mechanism includes a rotatable operating part and a stationary part, which adjoin at an interfacial plane. Tumblers each including a driver element and a follower element are mounted in bores in the parts, which bores meet in alignment at the interfacial plane, and the tumblers are movable back and forth in the bores. When the joints between the tumbler elements coincide with the interfacial plane upon insertion of a key, the operating part may be rotated by means of the key, to accomplish a desired function. The lock mechanism is provided with structure making it resistant to picking, including ledge means on the operating part adjacent to and intermediate the ends of a bore in the stationary part, and rib means on a follower element carried in the latter bore and adapted to overlappingly engage the ledge means when picking torque is applied to the operating part and while the joint of the tumbler which includes the latter follower element is displaced from the interfacial plane, for preventing longitudinal movement of the follower element in the direction of the interfacial plane.
