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 first housing;
a second housing rotatable within and with respect to the first housing;
a grip at least partially located within the second housing; and
a cable insertable in a first direction into a passage within at least one of
the first and second housings, the cable having a first state in which the cable is movable with respect to the second housing in the first direction but is restrained against movement with respect to the second housing in a second direction substantially opposite the first direction, and a second state in which the grip is movable about the passage;
wherein the cable is rotatable relative to the first housing when in the first state without deforming or damaging the cable; and
wherein the grip is movable to permit the cable to move in the first direction, is engageable with the cable to restrain the cable from moving in the second direction, and is freely movable about the passage in the second state of the cable.
2. The cable lock of claim 1 , wherein the grip is selected from the group consisting of a ball, a pin and a plate.
3. The cable lock of claim 1 , further comprising a third housing positioned within the first and second housings.
4. The cable lock of claim 3 , wherein the third housing is moveable axially with respect to the second housing.
5. The cable lock of claim 3 , wherein the third housing is rotatable with respect to the second housing in the second state of the cable.
6. The cable lock of claim 3 , wherein the grip is spring-loaded in the second direction.
7. The cable lock of claim 3 , wherein the cable is insertable into the second housing and rotatable with respect to the second housing in the second state of the cable.
8. The cable lock of claim 1 , wherein the grip is spring-loaded toward engagement with the cable.
9. The cable lock of claim 1 , wherein the first housing is crimped at an end thereof.
10. The cable lock of claim 1 , wherein the first housing has an open end, the cable lock further comprising an end cap positionable within the open end of the first housing, the first housing extending around an edge of the end cap to secure the end cap in the open end of the first housing.
11. The cable lock of claim 10 , wherein the end cap has a peripheral edge enclosed by the first housing.
12. A method of locking and preventing compromise of a cable lock, the method comprising the steps of:
inserting a cable into a housing in a first direction, the cable having a first state and a second state;
feeding the cable into the housing and past at least one grip;
rotating the at least one grip about the cable in the second state of the cable;
moving the cable to a position in which the cable is in the first state in which the cable is restrained from motion in a second direction substantially opposite the first direction; and
rotating the cable with respect to the housing in the position of the cable without deforming or damaging the cable.
13. The method of claim 12 , further comprising the steps of:
moving the grip within the housing with the cable;
permitting the cable to move in a first direction past the grip; and
resisting motion of the cable in a second direction substantially opposite the first direction with the grip.
14. The method of claim 13 , wherein the grip is selected from the group consisting of a ball, a pin and a plate.
15. The method of claim 13 , wherein the housing is a first housing, the method further comprising the step of feeding the cable into a second housing located at least partially within the first housing.
16. The method of claim 15 , further comprising the step of moving the second housing axially with respect to the first housing.
17. The method of claim 15 , further comprising the step of rotating the second housing within the first housing.
18. The method of claim 13 , further comprising the step of biasing the grip into engagement with the cable.
19. The method of claim 15 , further comprising the step of biasing the second housing in a direction opposite a direction of insertion of the cable into the second housing.
