Abstract
An interchangeable lock core for use with a key and having a locked state and an unlocked state is disclosed. The lock core may include a shell, a plug, and a lock. The plug may be positioned within and rotatable relative to the shell between a first plug position and a second plug position about a longitudinal axis of the plug. The plug may include a keyway adapted to receive the key. The lock may be rotatable about a lock axis between a first wherein a rotation of the plug is restricted and a second position wherein the plug is rotatable from the first plug position to the second plug position. The lock axis may be positioned outside of an envelope of the plug.
Claims21
A lock core for use with a key, the lock core comprising:
- a shell;
- a plug positioned within and rotatable relative to the shell between a first plug position and a second plug position about a longitudinal axis of the plug, the plug including a keyway adapted to receive the key;
- and
- a lock rotatable about a lock axis between a first position wherein a rotation of the plug is restricted by the lock and a second position wherein the plug is rotatable from the first plug position to the second plug position, the lock being rotatable within an envelope of the shell and the lock axis positioned outside of an envelope of the plug;
- wherein the lock is rotatable from the second position to a third position wherein a rotation of the plug is restricted.
A lock core for use with a key, the lock core comprising:
- a shell;
- a plug positioned within and rotatable relative to the shell between a first plug position and a second plug position about a longitudinal axis of the plug, the plug including a keyway adapted to receive the key;
- a blocker movable between a first position restricting rotation of the plug, a second position allowing rotation of the plug, and a third position restricting rotation of the plug;
- and
- a gear assembly positioned within the plug and configured to cause movement of the blocker between the first position, the second position, and the third position.
A lock core for use with a key, the lock core comprising:
- a shell;
- a plug positioned within and rotatable relative to the shell between a first plug position and a second plug position about a longitudinal axis of the plug, the plug including a keyway adapted to receive the key;
- a lock rotatable about a lock axis between a first position wherein a rotation of the plug is restricted by the lock and a second position wherein the plug is rotatable from the first plug position to the second plug position, the lock being rotatable within an envelope of the shell and the lock axis positioned outside of an envelope of the plug;
- and
- a lock actuator positioned within the lock passage of the plug, the lock actuator comprising a rack and a spring longitudinally aligned with the rack, the rack comprising a receiver, one end of the spring is received by the receiver, and another end of the spring is received by the plug, and the spring provides a biasing force to bias the lock to the first position;
- wherein the plug comprises a lock passage, and the lock is positioned in the lock passage.
