Electro-mechanical lock core
An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.
1. An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state, the lock device including an opening sized to receive the interchangeable lock core, the interchangeable lock core comprising:
a lock core body having a front end, a rear end, and an opening;
a moveable plug positioned within an interior of the lock core body proximate the rear end of the lock core body, the moveable plug having a first position relative to the lock core body, which corresponds to the lock device being in the locked state, and a second position relative to the lock core body, which corresponds to the lock device being in the unlocked state, the moveable plug being rotatable between the first position and the second position about a moveable plug axis;
a core keeper moveably coupled to the lock core body, the core keeper being positionable in a retain position wherein the core keeper extends beyond an envelope of the lock core body to hold the lock core body in the opening of the lock device and a remove position wherein the core keeper is retracted towards the lock core body relative to the retain position;
an operator actuatable assembly supported by the lock core body and including an operator actuatable input device positioned forward of the front end of the lock core body;
an electro-mechanical control system which in a first configuration operatively couples the operator actuatable input device of the operator actuatable assembly to the moveable plug and in a second configuration uncouples the operator actuatable input device of the operator actuatable assembly from the moveable plug; and
an actuator accessible from an exterior of the lock core body, the actuator operatively coupled to the core keeper independent of the moveable plug to move the core keeper from the retain position to the remove position;
wherein the operator actuatable input device blocks access to the opening in the lock core body when the operator actuatable input device is coupled to the lock core body.
2. The interchangeable electro-mechanical lock core of claim 1 , wherein the actuator is a mechanical actuator.
3. The interchangeable electro-mechanical lock core of claim 1 , wherein the actuator is completely internal to the lock core body.
4. The interchangeable electro-mechanical lock core of claim 3 , wherein the actuator is accessible through the opening in the lock core body.
5. The interchangeable electro-mechanical lock core of claim 1 , further comprising a control sleeve, wherein at least one of the actuator and the control sleeve includes a blocker which limits a movement of the actuator.
6. The interchangeable electro-mechanical lock core of claim 5 , wherein the actuator includes the blocker.
7. The interchangeable electro-mechanical lock core of claim 5 , wherein the control sleeve includes the blocker.
8. The interchangeable electro-mechanical lock core of claim 5 , wherein the control sleeve includes a first partial gear and the actuator includes a second partial gear, the first partial gear and the second partial gear are intermeshed to operatively couple the actuator to the core keeper.
9. The interchangeable electro-mechanical lock core of claim 8 , wherein the actuator includes the blocker and the blocker interacts with the first partial gear of the control sleeve to limit a rotational movement of the actuator.
10. The interchangeable electro-mechanical lock core of claim 8 , wherein the actuator includes the blocker and the blocker interacts with the control sleeve to limit a translational movement of the actuator.
11. The interchangeable electro-mechanical lock core of claim 8 , wherein the control sleeve includes the blocker and the blocker interacts with the second partial gear of the actuator to limit a translational movement of the actuator.
12. The interchangeable electro-mechanical lock core of claim 8 , wherein the control sleeve includes the blocker and the blocker interacts with the second partial gear of the actuator to limit a rotational movement of the actuator.
13. The interchangeable electro-mechanical lock core of claim 1 , wherein the actuator includes a recess which receives a stop member supported by the lock core body.
14. The interchangeable electro-mechanical lock core of claim 13 , wherein the stop member is positioned above the actuator and the moveable plug is positioned below the actuator.
15. An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state, the lock device including an opening sized to receive the interchangeable lock core, the interchangeable lock core comprising:
a lock core body having a front end and a rear end, the lock core body further having an upper portion having a first maximum lateral extent, a lower portion having a second maximum lateral extent, and a waist portion having a third maximum lateral extent, the third maximum lateral extent being less than the first maximum lateral extent and being less than the second maximum lateral extent;
a moveable plug positioned within an interior of the lock core body proximate the rear end of the lock core body, the moveable plug having a first position relative to the lock core body, which corresponds to the lock device being in the locked state and a second position relative to the lock core body, which corresponds to the lock device being in the unlocked state, the moveable plug being rotatable between the first position and the second position about a moveable plug axis;
a core keeper moveably coupled to the lock core body, the core keeper being positionable in a retain position wherein the core keeper extends beyond an envelope of the lock core body to hold the lock core body in the opening of the lock device and a remove position wherein the core keeper is retracted towards the lock core body relative to the retain position;
a control sleeve having an opening, the moveable plug being received in the opening of the control sleeve, the core keeper extending from the control sleeve;
an operator actuatable assembly supported by the lock core body and including an operator actuatable input device positioned forward of the front end of the lock core body; and
an actuator operatively coupled to the control sleeve independent of the moveable plug to move the core keeper from the retain position to the remove position, the actuator having a first gear portion which is operatively coupled to a second gear portion of the control sleeve.
