Abstract

An interchangeable core assembly for a lock core assembly capable of being flush mounted in a door including a housing, a lock insert mounted in the housing, a lock core mounted in the housing adjacent to and cooperative with the lock insert, a thumb-turn assembly mounted in the non-cylindrical housing coaxial with the lock core, a first offset cam mounted on the thumb-turn assembly for rotation therewith, and a second offset cam mounted on the lock core for rotation therewith. The barrel of the lock core assembly is unobstructed by locking train components such that the lock core assembly extends completely through the latch assembly when installed therein. The lock core assembly is secured to the latch assembly without threads and a means to remove/replace the thumb-turn component is provided.

First claim

What is claimed is:

1. A flush-mounted lock core assembly connectable to a latch assembly in a door stile, the door stile having an outer surface and an opening for receiving the lock core assembly, the lock core assembly comprising:
a housing including an outermost face, an inner face; and
a core including a core outermost face,
wherein the housing includes a channel configured for receiving the core, and
wherein when the opening of the door stile receives said lock core assembly, the outermost face of the housing is flush with the outer surface of the door stile.

2. A flush-mounted lock core assembly in accordance with claim 1 wherein when the opening in the door stile receives the lock core assembly, the outermost face of the housing and the core outermost face are flush with the outer surface of the door stile.

3. A flush-mounted lock core assembly in accordance with claim 1 further comprising a core insert including a core insert outermost face, wherein when the opening in the door stile receives the lock core assembly, the outermost face of the housing, the core outermost face, and the core insert outermost face are flush with the outer surface of the door stile.

4. A flush-mounted lock core assembly in accordance with claim 3 wherein the core is an interchangeable core, and wherein the core insert is an interchangeable core insert.

5. A flush-mounted lock core assembly in accordance with claim 1 wherein the housing includes a cross-sectional shape, and wherein the cross-sectional shape is circular.

6. A flush-mounted lock core assembly in accordance with claim 1 wherein the housing includes a cross-sectional shape, and wherein the cross-sectional shape is non-circular.

7. A flush-mounted lock core assembly in accordance with claim 6 wherein the latch assembly includes an opening for receiving the lock core assembly, and wherein the latch assembly opening is shaped similarly to the cross-sectional shape of the housing to prevent the latch core assembly from being twisted relative to the opening of the latch assembly.

8. A flush-mounted lock core assembly in accordance with claim 6 , wherein the cross-section shape is elongated.

9. A flush-mounted lock core assembly in accordance with claim 6 , wherein the cross-section shape is elliptical.

10. A flush-mounted lock core assembly in accordance with claim 1 wherein the housing includes an outer surface, and wherein the outer surface of the housing is not threaded.

11. A flush-mounted lock core assembly in accordance with claim 1 wherein the housing includes a length measured between the outermost face of the housing and the inner face of the housing, wherein the door stile includes an inner wall, and wherein when the opening in the door stile receives the lock core assembly, the inner face of the housing is close to or touching the inner wall of the door stile.

12. A flush-mounted lock core assembly in accordance with claim 11 wherein the door stile includes a recess for receiving the housing, and wherein the length of the housing is full fitting in the recess when the door stile receives the lock core assembly.

13. A flush-mounted lock core assembly in accordance with claim 1 wherein the core is an interchangeable core.
