Abstract

A locking device is provided for locking a container having sidewalls and at least one lid defining an open position and a closed position. The locking device may include an elongate lock member configured to engage the lid(s) and a lock housing that is associated with at least one of the sidewalls. The lock housing may be configured to at least partially receive the elongate lock member. The locking device may be designed to be installed on the container in the field, or the locking device may be integrally formed with the container. The lock housing may include a security element that is detectable by a security system to guard against theft of the container. In some cases, a security module is provided that releasably attaches to the lock housing to provide further alarm functionality.

3. The locking device of claim 1, wherein the lock housing further comprises an audible alarm device and an energy source.

4. The locking device of claim 1, wherein the lock housing further comprises an audible alarm device, an energy source, and a sense loop configured to detect a fault condition associated with the locking device.

5. The locking device of claim 1 further comprising a security module configured to be releasably attached to the lock housing, wherein the security module comprises an audible alarm device and an energy source.

6. The locking device of claim 1 further comprising a security module configured to be releasably attached to the lock housing, wherein the security module comprises an audible alarm device, an energy source, and a logic circuit disposed in communication with at least a portion of the elongate lock member to form a sense loop configured to detect a fault condition associated with the locking device.

7. The locking device of claim 1, wherein the elongate lock member is configured to engage the at least one lid, and the lock housing is securely fastened to the at least one of the sidewalls.

8. The locking device of claim 7, wherein the container defines a handle, and wherein the lock housing is securely fastened to the at least one of the sidewalls proximate the handle.

9. The locking device of claim 1, wherein the elongate lock member is configured to engage the at least one lid, and wherein the at least one of the sidewalls at least partially forms the lock housing.

10. The locking device of claim 1, wherein the elongate lock member defines a locking surface, and wherein the lock assembly comprises a locking slider that is spring biased to engage a locking surface of the elongate lock member.

11. The locking device of claim 1, wherein the flexible cable of the elongate lock member defines a locking surface, and wherein the lock assembly is configured to engage the locking surface of the flexible cable when the lock assembly is in a locked position.

12. The locking device of claim 11, wherein the lock assembly is configured to engage the locking surface of the flexible cable when the flexible cable is in the retracted position.

13. The locking device of claim 12, wherein a retraction force is required to drive the flexible cable from the extracted position to the retracted position.

14. The locking device of claim 13, wherein the flexible cable defines a driving element configured to be grasped by a user when applying the retraction force.

15. The locking device of claim 13, wherein the at least one lid comprises a cable retaining element configured to frictionally resist movement of the flexible cable from the extracted position to the retracted position.

16. The locking device of claim 13, wherein the flexible cable defines a drive rigidity for reducing buckling of the flexible cable when the retraction force is applied.

17. The locking device of claim 1, wherein the container comprises a first lid and a second lid, and wherein the elongate lock member is configured to engage and secure the first lid and the second lid in the closed position when the lock assembly is in the locked position.

18. The locking device of claim 1, wherein the container comprises a first lid and a second lid, and wherein the elongate lock member is configured to engage and secure the first lid and the second lid in the closed position when the lock assembly is in a locked position.

19. The locking device of claim 18, wherein the elongate lock member is configured to remain with the first lid when the elongate lock member is in an extracted position and the first lid is in the open position.

20. A locking device for locking a container having sidewalls and at least one lid defining an open position and a closed position, the locking device comprising:

a flexible cable configured to engage the at least one lid and defining a locking surface, the flexible cable being configured to travel between a retracted position and an extracted position;

a lock housing associated with at least one of the sidewalls, wherein the lock housing is configured to at least partially receive the flexible cable, wherein the lock housing comprises a locking slider defining a locked position and having an engagement surface, wherein the engagement surface is configured to engage the locking surface of the flexible cable and secure the at least one lid in the closed position when the locking slider is in the locked position; and

a guide element fixedly disposed to the lock housing, the guide element being configured to direct the flexible cable in a substantially linear direction towards the lock housing as the flexible cable is driven from the extracted position to the retracted position,

wherein the entire flexible cable is maintained in a substantially linear form when the locking surface of the flexible cable is lockably engaged with the engagement surface of the locking slider.

21. The locking device of claim 20, further comprising a security element selected from the group consisting of an RFID transponder and an EAS element.
