Abstract

An exemplary lock re-pinning fixture includes a first housing releasably joined with a second housing, and a follower bar positioned at least partially in the second housing. The follower bar may be structured for a plurality of orientations within the housings, and may be biased toward the first housing. The first housing may be configured to receive a lock cylinder such that the plug of the cylinder is aligned with the follower bar. Further embodiments, forms, features, aspects, benefits, and advantages of the present application shall become apparent from the description and figures provided herewith.

First claim

What is claimed is:

1. A system, comprising:
a front housing mounted to a rear housing;
a lock assembly removably housed in said front housing, and comprising a lock body and a lock core;
one or more top pins housed in said lock body;
one or more bottom pins housed in said lock core;
a biasing element mounted in said rear housing; and
a follower bar removably housed in said rear housing;
wherein said biasing element biases said follower bar against said lock core, said follower bar and said lock core being stationary with respect to one another;
said lock body having plurality of positions with respect to the lock core, the plurality of positions comprising:
a first position in which said one or more top pins and said one or more bottom pins are contained by said lock body and said lock core; and
a second position in which said one or more top pins are contained by said lock body and said follower bar.

2. The system of claim 1 , wherein said follower bar is structured for multiple orientations within said rear housing.

3. The system of claim 1 , wherein said follower bar comprises one or more end features matingly engageable with said lock assembly.

4. The system of claim 1 , wherein said front housing and said rear housing are removably mounted via bayonet attachment features.

5. The system of claim 1 , wherein the plurality of positions further comprises a third position in which said one or more bottom pins are exposed.

6. A fixture structured for re-pinning a lock assembly comprising:
a first housing having a first housing interior mounted to a second housing having a second housing interior;
said first housing interior and said second housing interior being in communication with one another when said first housing is mounted to said second housing;
a follower bar removably housed within said second housing interior, wherein said follower bar extends in a longitudinal direction and includes a first end having a first geometry and an opposite second end having a second geometry different from said first geometry, wherein each of the first geometry and the second geometry comprises a flat surface and at least one longitudinal protrusion; and
wherein said follower bar is structured for a plurality of orientations within said second housing interior.

7. A fixture structured for re-pinning a lock assembly comprising:
a first housing mounted to a second housing;
said first housing and said second housing being in communication with one another, wherein said first housing is received at least partially within said second housing;
a follower bar removably housed within said second housing, wherein the follower bar comprises a first end and an opposite second end, and wherein the first end of the follower bar comprises a recess having an elliptical cross-section; and
wherein said follower bar is structured for a plurality of orientations within said second housing, and wherein the second end of the follower bar comprises a protrusion having a circular cross-section.

8. The fixture of claim 6 , wherein said second housing interior and said follower bar include one or more keys that are selectively engaged with a plurality of key ways to provide said plurality of orientations of said follower bar within said second housing interior.

9. The fixture of claim 8 , wherein said plurality of key ways are defined by said follower bar, and wherein said one or more keys are defined by said second housing interior.

10. A fixture structured for re-pinning a lock assembly comprising:
a first housing mounted to a second housing;
said first housing and said second housing being in communication with one another;
a follower bar removably housed within said second housing; and
a biasing element mounted within said second housing, said biasing element biases against said follower bar; and
wherein said follower bar is structured for a plurality of orientations within said second housing.

11. The fixture of claim 10 , wherein said biasing element biases said follower bar toward said first housing.

12. A system, comprising:
a first housing removably joined to a second housing;
a lock assembly comprising a lock plug and an outer casing, said lock assembly being removably mounted in said first housing;
a biasing element housed in said second housing;
a first follower bar housed in said second housing and said biasing element biasing said first follower bar toward said first housing; and
wherein said first follower bar comprises a plurality of key ways and said second housing comprises one or more keys, said key ways being structured for a plurality of engagement orientations with said keys.

13. The system of claim 12 , wherein said first follower bar and said lock plug are stationary with respect to one another.

14. The system of claim 12 , wherein said first follower bar has at least one structural end feature matingly engageable with said lock plug.

15. The system of claim 12 , further comprising a second follower bar, wherein said second follower bar is interchangeable with said first follower bar.

16. The system of claim 12 , further comprising a plurality of top pins housed in said outer casing, and a plurality of bottom pins housed in said lock plug, said outer casing comprising at least a first position with respect to said lock plug wherein said plurality of top pins and said plurality of bottom pins are captured by said outer casing and said lock plug.

17. The system of claim 16 , wherein said outer casing comprises at least a second position with respect to said lock plug wherein said plurality of top pins are captured by said outer casing and said first follower bar.

18. The system of claim 16 , wherein said outer casing comprises at least a second position with respect to said lock plug wherein said plurality of bottom pins are removable.

19. The fixture of claim 6 , wherein the at least one protrusion of the first geometry comprises a circular protrusion, and wherein the at least one protrusion of the second geometry comprises a pair of crescent-shaped protrusions.
