- a locking bar comprising a plurality of sequential teeth formed in a side of the locking bar;
a pivoting locking lever that engages the teeth of the locking bar, wherein the locking bar is slidable relative to the teeth of the locking lever;
wherein the locking bar acts as a cam, and the locking lever acts as a cam follower, and the locking lever sequentially engages the teeth of the locking bar as the locking bar slides relative to the teeth; and

Abstract
An electro-mechanical lock for cargo containers or similar enclosed spaces such as storage units. The locking mechanism includes a dual-ratcheting mechanism, which is normally in the locked position, and which firmly secures doors of a container or other enclosure. To unlock the device, the user obtains a temporary access code and unlocks the device, either by a wireless interface or by, for example, a key pad. The device incorporates a rolling access code algorithm that changes the access code based upon a pre-defined customer selected time period during which the code is valid. Once the validity period expires the user must obtain a new access code from a secure access code source to unlock the device. When access is desired, the user contacts a remote secure access code source, which provides the access code for the associated lock and time period.
