Abstract: An interchangeable electronic lock mechanism provides selective access to a motor controlled latching system including a motorized pin to lock and unlock a knob assembly. The lock mechanism may be used to replace key operated locking cores, on the exterior of a storage unit, with a plug and optional adapter inserted into a remaining shell housing, and a driver to control access to a storage unit. Manual rotation of the knob activates the drive assembly to control access to the storage unit. An optional break away security feature in the knob inhibits unauthorized unlatching of the lock. When the lock is unlatched, the knob rotates the drive assembly including the plug and adapter within the shell housing, and in turn, activates the driver to operate the lock assembly in the storage unit. An optional modular chassis assembly includes a removable array of components for testing, maintenance and repair.

Abstract: A weather resistant tumbler lock has an elongated body, and defines a longitudinal axis. The lock is interchangeable with another lock having a corresponding asymmetrical perimeter profile with an opening in a top surface sealed with a cap, the other lock having a different rotatable core and a different configuration of tumblers. A drainway provides a channel for water to flow outwardly from the interior of a shell housing, a rotatable core and a keyway within the core, to a drain below the lock. The drain connects to a channel through a lower edge. The core provides an arcuate gap in a lower quadrant adjacent the interior surface of the shell for fluid communication with the drainway. A method includes identifying a substitute tumbler lock with an impermeable outer wall for replacing another lock having an identical outer perimeter profile and a permeable closed opening on its top surface.

Abstract: A cammed lever is configured to nest and lock with a cam follower at a recess formed on the cammed lever or the cam follower. Upon rotation of the lever, the cam follower and the cammed lever are disengaged at the recess to form a gap when the cammed lever is rotated upon outward movement of a drawer or drawer slide. The lock assembly includes the cammed lever and cam follower in a stacked array for use in a storage unit having multiple drawers. Preferably, only one drawer is permitted to open in the stacked array. The cammed lever, when unlocked, is permitted to rotate between the open and closed positions. When locked, the cam follower prevents rotation of the cammed lever to an open position. An optional sliding bracket is provided for added security when the drawers are locked.

Abstract: A weather resistant pin lock with an elongated body, defining a longitudinal axis includes a shell housing a rotatable core having a keyway. An elevated pinway projects upwardly from the shell to define a linear array of pin slots containing a set of lock pins. A hood is fastened to the pinway to hold the lock pins in the pin slots and to provide a water resistant barrier. A drainway provides a channel for water to flow outwardly from the interior of the shell, the rotatable core and the keyway within the core, to a drain below the pin lock. At the proximate end, an access door rotates adjacent the keyway at an elevated position, to provide a gap along the bottom edge of the access door.

Abstract: An interchangeable electronic lock includes an electronic access system to activate a motor which powers a gear assembly in the electronic lock. An optional manual bypass allows an operator to override the electronic access. When the lock is activated, the operator manually cranks a lock shaft to lock and unlock a storage unit. A controller selectively operates the motor to move the gear assembly in a linear direction. The gear assembly engages a first portion of a drive assembly with a second portion, to permit manual operation of the lock shaft to lock and unlock the storage unit. An optional modular chassis assembly includes a removable array of components for testing, maintenance and repair. The invention includes a system for operation of the electronic lock, a method of operating the electronic lock and software for operating the electronic lock.

Abstract: A locking apparatus includes a fixed housing with a longitudinal elongated bore between two open ends. One end defines an arcuate track with a new rotational displacement range. A pivoting riser extends from a driver to an elongated retainer moving across a locking core configured with a predefined rotational range. A follower on the driver travels within the track. The core and the driver may be connected and inserted via the same open end for rotation within the bore. When the locking core is unlocked and rotated with an operating key, the riser displaces the retainer to retain the core within the housing, while the follower continues to rotate within the track so that the rotational range of the core is changed to the new rotational displacement range. The apparatus may include the core. The apparatus may exclude the core to allow separate installation for combined rotation with the driver.

Abstract: An electronic lock is interchangeable with mechanical locks in retrofit applications or as an OEM lock. The lock includes interchangeable modular components. The lock housing is interchangeable with other housings of different configurations to permit replacement of existing mechanical locks. The lock may also include interchangeable drivers for compatibility with other systems. The lock includes an electronic access system such as a programmable keypad or card reader to activate a motor which powers the electronic lock. An optional manual bypass allows an operator to override the electronic access, for example when the motor is inoperative. When the lock is activated, the operator manually cranks a lock shaft to lock and unlock a storage unit. An optional modular chassis assembly includes a removable array of components for testing, maintenance and repair.

Abstract: A locking system or a storage unit with the locking system, includes a locking core and a connected cammed lever. A user can rotate the core and lever about an axis when a latch is disengaged from a detent. When the latch is engaged with the detent, the core and the cammed lever are prevented from rotating about the axis. When the locking assembly is installed within the storage unit, the latch may be configured to strike a guide associated with a locking bar assembly, so that when the latch is moved to an unlatched position, the locking core and the lever are free to rotate, operating the locking bar between locked and unlocked positions. When the latch is withdrawn away from the guide, the latch engages with the detent to prevent movement of the lever and locking core relative to the locking assembly, to retain the lever and locking core in a desired, predetermined orientation.
