Patent ID: 7640773

Claim:
A portion of a lock, comprising: a stationary member having a bore and being mountable to an object; a movable member positioned at least partially within the bore and movable relative to the bore in an unlocking direction during a normal unlocking operation; a non-resilient deformable portion positioned adjacent an interface between the stationary member and the movable member, the non-resilient deformable portion being fixed to one of the stationary member and the movable member, wherein the deformable portion permits the movable member to move in the unlocking direction during a normal unlocking operation, and wherein the deformable portion is deformable to prevent movement of the movable member relative to the stationary member when subjected to excessive force applied in an attempt to move the movable member in the unlocking direction in other than a normal unlocking operation; and a locking member comprising a locking bar extending along a longitudinal axis of the portion of the lock and comprising a first end and a second end, the first end being configured to move radially inward relative to the movable member, the locking member being engageable with the stationary member and the movable member to resist movement of the movable member relative to the stationary member, the locking member being positioned adjacent the deformable portion such that the excessive force applied to the movable member causes the first end of the locking member to deform the deformable portion.
