Abstract

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical 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.

First claim

We claim:

1. An interchangeable 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 an interior, the lock core body including 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, the lower portion, the upper portion, and the waist portion forming an envelope of the lock core body;
a moveable plug positioned within a first portion of the interior of the lock core body proximate a first 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 a 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 the 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 within the envelope of the lock core body to permit removal of the lock core body from the opening of the lock device;
an electronically controlled blocker positioned in the interior of the lock core body, the electronically controlled blocker being moveable between a blocking position and a release position; and
an operator actuatable assembly including an operator actuatable input device extending beyond a second end of the lock core body, wherein the operator actuatable input device blocks access to the interior of the lock core body, the moveable plug is movable from the first position to the second position with the operator actuatable input device being assembled to the lock core body, and the operator actuatable input device must be removed from a remainder of the interchangeable lock core prior to moving the core keeper from the retain position to the release position.

2. The interchangeable core of claim 1 , further comprising a control sleeve rotatable about the moveable plug axis, the control sleeve supporting the core keeper.

3. The interchangeable core of claim 2 , wherein the moveable plug is received within an interior of the control sleeve.

4. The interchangeable core of claim 3 , wherein the control sleeve is positioned in the interior of the lock core body.

5. The interchangeable core of claim 3 , wherein the lower portion of the lock core body includes an opening and the control sleeve is positioned in the opening of the lower portion of the lock core body.

6. The interchangeable core of claim 3 , further comprising at least a first coupler received in at least a first opening of the moveable plug, the first coupler being moveable in a direction angled relative to the moveable plug axis to couple the control sleeve to the moveable plug such that a rotation of the moveable plug about the moveable plug axis causes a rotation of the control sleeve about the moveable axis.

7. The interchangeable core of claim 6 , wherein moveable plug includes a central keyway along the moveable plug axis, the first coupler extending into the central keyway, wherein with the operator actuatable input device removed from the remainder of the interchangeable lock core, the keyway is accessible from the second end of the lock core body.

8. An interchangeable 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 an interior, the lock core body including 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, the lower portion, the upper portion, and the waist portion forming an envelope of the lock core body;
a moveable plug positioned within a first portion of the interior of the lock core body proximate a first 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 a 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 the 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 within the envelope of the lock core body to permit removal of the lock core body from the opening of the lock device;
a control element positionable within the waist portion, an end of the control element having a first vertical position when the core keeper is in the retain position and a second vertical position when the core keeper is in the remove position; and
an operator actuatable assembly including an operator actuatable input device extending beyond a second end of the lock core body, the second end being opposite the first end.

9. The interchangeable lock core of claim 8 , wherein the operator actuatable input device blocks access to the interior of the lock core body, the moveable plug is movable from the first position to the second position with the operator actuatable input device being assembled to the lock core body, and the operator actuatable input device must be removed from a remainder of the interchangeable lock core prior to moving the core keeper from the retain position to the release position.

10. The interchangeable lock core of claim 8 , further comprising a control sleeve rotatable about the moveable plug axis, the control sleeve supporting the core keeper.

11. The interchangeable core of claim 10 , wherein the moveable plug is received within an interior of the control sleeve.

12. The interchangeable core of claim 11 , wherein the lower portion of the lock core body includes an opening between the first end of the lock core body and the second end of the lock core body and the control sleeve is positioned in the opening of the lower portion of the lock core body.

13. The interchangeable lock core of claim 11 , wherein the operator actuatable input device blocks access to the interior of the lock core body, the moveable plug is movable from the first position to the second position with the operator actuatable input device being assembled to the lock core body, and the operator actuatable input device must be removed from a remainder of the interchangeable lock core to expose an opening into the interior of the lock core body.

14. The interchangeable lock core of claim 13 , further comprising an elongated tool receivable by the opening into the interior of the lock core body and operatively coupled to the control sleeve when inserted into the interior to a first depth, wherein a rotation of the elongated tool at the first depth results i
