20100024496Electric Locks with Release Hammer - Electric lock with hammer for doors, locker doors, safe doors, telephone chassis, vending machines and the like which also have an anti jamming mechanism. To close the electric lock, the bar moves forward and the door latch closes upon a corresponding bolt. When moving forward, the bar stretches the spring into a tense state. The latch drops into a corresponding groove and mechanically locks the bar. To unlock the electric lock the solenoid activates the hammer while applying most of the energy over a relatively short period of time. The hammer in turn hits the latch out of its groove to unlock the electric lock. The spring pulls the bar backwards and the door latch opens up. According to the present invention, when mechanical pressure is applied upon any of lock mechanical components, the hammer strikes at the latch repeatedly until it comes out of its groove and the unlocks.02-04-2010

A second urging arrangement is operative to bias the actuation member to move to the second state. A third urging arrangement is operative to bias the actuation member to move from the second to the first state. The plunger is operatively associated with the locking assembly to cause said lock actuation member to move from the first to the second state for unlocking the lock upon displacement of the plunger in the first direction, and to permit movement of the actuation member, induced by the third urging arrangement, from the second to the first state for locking the lock, upon displacement of the plunger from the extended to the retraced state.12-17-2009

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.09-13-2012
