Lock portion with deformable features

An anti-attack portion of a lock, comprising:

• a stationary outer body comprising a generally circular bore having a contiguous channel formed therein;
• a rotatable generally cylindrical inner core positioned at least partially within the circular bore and rotatable relative to the stationary outer body, the rotatable cylindrical inner core having a recess formed therein;
• non-resilient deformable members adjacent an interface between the stationary outer body and the rotatable cylindrical inner core;
• and
• a movable 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 rotatable cylindrical inner core, the movable locking member being positioned at least partially within the recess and between the deformable members such that the deformable members are adjacent laterally opposed sides of the movable locking member, a portion of the movable locking member being engageable with the channel to resist rotation of the inner core relative to the outer body when the lock is in a locked state and disengageable from the channel when the lock is in an unlocked state;
• wherein rotation of the inner core relative to the outer body when the lock is in the locked state urges the locking member against at least one of the deformable members, and wherein further rotation exceeding a predetermined torsional force causes the locking member to deform at least one of the deformable members, thereby preventing rotation of the inner core relative to the outer body.

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, wherein the deformable portion permits the movable member to move in the unlocking direction during 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 an excessive force applied to the movable member in the unlocking direction in other than the normal unlocking operation causes the locking member to deform the deformable portion and occupy a void created by the deformation of the deformable portion.
