Cable lock and method
Some embodiments of the cable lock provide a body defining a housing in which a cable can be received to lock the cable lock. In some embodiments, the cable is rotatable with respect to the housing when the cable lock is in a locked state, thereby increasing the difficulty of circumventing the lock. The cable lock can have a wall with an aperture shaped to compliment the cross-sectional shape of the cable passed therethrough, an end wall that can be attached to the housing by rolling or crimping an edge of the housing over the end wall, and/or one or more visual indicators providing a manner by which tampering of the cable lock can be detected.
1. A cable lock, comprising:
a housing having an internal cavity, at least a majority of the internal cavity being substantially filled with a flowable medium;
a cable having an end insertable into the internal cavity of the housing to lock the cable lock; and
a barrier positioned within the internal cavity and punctured by the cable upon insertion of the cable into the housing.
2. The cable lock of claim 1 , wherein the flowable medium is a lubricant.
3. The cable lock of claim 1 , wherein the flowable medium comprises grease.
4. The cable lock of claim 1 , wherein the barrier is a frangible barrier through which the cable is inserted.
5. The cable lock of claim 4 , wherein the barrier is a sheet of material punctured by the cable.
6. The cable lock of claim 1 , wherein the cable is movable through the housing in a first direction but not in a direction opposite the first direction.
7. A method of assembling a cable lock, comprising:
providing a housing having an internal cavity;
filling at least a majority of the internal cavity with a flowable medium;
inserting a cable into an aperture in the housing and in a first direction through the flowable medium; and
securing the cable within the housing against removal from the aperture in a second direction substantially opposite the first direction while allowing the cable within the housing to move with respect to the housing in the first direction.
8. The method of claim 7 , wherein the flowable medium is a lubricant.
9. The method of claim 7 , wherein the flowable medium comprises grease.
10. The method of claim 7 , further comprising substantially filling the internal cavity with the flowable medium.
11. The method of claim 7 , further comprising puncturing a barrier with the cable.
12. The method of claim 11 , further comprising retaining at least some of the flowable medium in the housing with the barrier.
13. A cable lock, comprising:
a housing having an internal cavity;
a flowable medium occupying at least a majority of the internal cavity; and
a cable insertable into the housing in a first direction, the cable lock having a first state within the housing in which the cable is movable with respect to the housing in the first direction but is restrained against movement with respect to the housing in a second direction substantially opposite the first direction;
wherein the cable is rotatable relative to the housing in the first state of the cable lock.
14. The cable lock of claim 13 , wherein the flowable medium is a lubricant.
15. The cable lock of claim 13 , wherein the flowable medium comprises grease.
16. The cable lock of claim 13 , wherein the internal cavity of the housing is substantially filled with the flowable medium.
17. The cable lock of claim 13 , further comprising a frangible barrier through which the cable is insertable.
18. The cable lock of claim 17 , wherein the frangible barrier is a sheet of material punctured by the cable.
19. The cable lock of claim 13 , wherein the cable is rotatable within the housing in the first state.
