Abstract

A lock re-pinning assembly including two or more housings and a mounting block. Each housing is configured for use with a corresponding one of a plurality of lock cylinder shells. Each of the housings includes a cylindrical chamber and a channel. The chamber is configured to receive the body of the corresponding shell, and the channel is configured to receive the tower of the corresponding shell. The mounting block includes a mounting block having two or more sections. Each section is configured for use with a corresponding one of a plurality of lock cylinder plugs. Each section includes a cavity configured to receive an end of at least one of the housings, and a cylindrical follower bar having a diameter substantially equal to a diameter of the corresponding plug. Each of the housings is releasably engageable with the mounting block at each of the plurality of sections.

First claim

What is claimed is:

1. A lock re-pinning assembly, comprising:
a plurality of housings, wherein each housing is configured for use with a corresponding one of a plurality of lock cylinder shells, each of the shells includes a cylindrical body and a tower extending from the body, each of the housings including:
a first end and an opposite second end, wherein the first end is open, the second end includes a face, and the face has an opening configured to receive a key;
a cylindrical chamber extending from the first end, the chamber sized and configured to receive the body of the corresponding shell; and
a channel extending from the first end, the channel sized and configured to receive the tower of the corresponding shell; and

a mounting block including a plurality of sections, wherein each section is configured for use with a corresponding one of a plurality of lock cylinder plugs, each of the sections including:
a cavity configured to receive the first end of at least one of the housings; and
a cylindrical follower bar extending into the cavity and having a diameter substantially equal to a diameter of the corresponding plug; and

wherein each of the plurality of housings is releasably engageable with the mounting block at each of the plurality of sections.

2. The lock re-pinning assembly of claim 1 , wherein each of the housings further includes a partial circumferential opening connected with the channel, wherein the partial circumferential opening is sized and configured to receive the tower of the corresponding shell and to enable limited rotational movement of the corresponding shell when the tower is received therein.

3. The lock re-pinning assembly of claim 1 , wherein each of the follower bars includes an end portion configured to flushly engage at least a portion of a back end of the corresponding plug.

4. The lock re-pinning assembly of claim 1 , wherein the housings and the mounting block further comprise attachment features, and the attachment features are configured to releasably couple the housings to the mounting block with the first ends received in the cavities.

5. The lock re-pinning assembly of claim 1 , wherein each of the housings is releasably coupled to a corresponding one of the sections, the first end of each of the housings is received in the cavity of the corresponding section, and each follower bar projects into the chamber of the corresponding housing.

6. The lock re-pinning assembly of claim 1 , wherein the mounting block is a single-piece unitary structure including each of the follower bars.

7. A method of using the lock re-pinning assembly of claim 1 , the method comprising:
selecting a lock cylinder including a shell, a plug seated in the shell, a plurality of driving pins, and a first plurality of driven pins, wherein the shell has a first of the plurality of shell formats, and the plug has a first of the plurality of plug formats;
selecting from the plurality of housings a first housing corresponding to the first shell format;
selecting from the plurality of sections a first section corresponding to the first plug format;
positioning the body of the shell in the chamber of the first housing;
aligning a back end of the plug with the follower bar of the first section; and
coupling the first housing to the mounting block with the back end of the plug aligned with the follower bar of the first section.

8. An assembly configured for use with each of a plurality of lock cylinder formats, wherein each of the lock cylinder formats includes one of a plurality of shell formats and one of a plurality of plug formats, each of the shell formats includes a cylindrical body and a tower connected to the body at a tower base, and each of the plug formats includes a curved outer surface and a back end, the assembly comprising:
a plurality of housings, wherein each of the housings is configured for use with a corresponding one of the shell formats, each of the housings including:
a distal end and a proximal end, wherein the distal end is open, the proximal end includes a face, and the face has an opening configured to receive a key;
a cylindrical chamber extending proximally from the distal end and sized and configured to receive the body of the corresponding shell format; and
a channel extending proximally from the distal end and sized and configured to receive the tower base of the corresponding shell format;

a mounting block including a plurality of sections, wherein each section includes a cavity, and each of the housings is operable to be releasably coupled to each of the sections with the chamber in communication with the cavity; and
a plurality of follower bars, wherein each of the follower bars extends proximally into one of the cavities, each of the follower bars is configured for use with a corresponding one of the plurality of plug formats, each of the follower bars including:
a follower surface having curvature corresponding to curved outer surface of the corresponding plug format; and
an end portion configured to engage the back end of the corresponding plug format; and
wherein, with the end portion engaged with the back end of the corresponding plug format, at least a portion of the curved outer surface is substantially flush with the follower surface.

9. The assembly of claim 8 , wherein the follower bars are integrally formed with the mounting block to define a single piece monolithic structure.

10. The assembly of claim 8 , wherein each section further comprises a mounting block channel configured to connect to the channel of each of the housings when the housing is coupled to the section.

11. The assembly of claim 8 , wherein each of the sections further comprises a first alignment feature, and each of the housings further comprises a second alignment feature configured to engage one of the first alignment features when the housing is coupled to each of the sections.

12. The assembly of claim 11 , wherein each of the first alignment features comprises one of a protrusion and a slot, each of the second alignment features comprises the other of the protrusion and the slot, and each of the slots is sized and configured to receive each of the protrusions.

13. The assembly of claim 8 , wherein the mounting block has a hollow interior which opens to a distal side of the mounting block, wherein the assembly further comprises a counterweight, and wherein the counterweight is positioned in the hollow interior.

14. The assembly of claim 13 , wherein the counterweight includes a plurality of recesses configured to receive the housings, and a plurality of arms operable to releasably couple the housings to the counterweight.

15. The assembly of claim 8 , wherein each of the sections includes a ridge, and each of the housings includes a hook configured to engage each of the ridges to releasably couple the housing to the mounting block at each of the sections.

16. An assembly, comprising:
a plurality of housings, including:
a first housing including a first housing attachment feature, a first cylindrical chamber extending proximally from a distal end of the first housing, a first housing channel extending proximally from the distal end of the first housing, and a first partial circumferential opening connected with the first channel, the first partial circumferential opening having a first axial length;
a second housing including a second housing attachment feature, a second cylindrical chamber extending proximally from a distal end of the second housing, a second housing channel extending proximally from the distal end of the second housing, and a seco
