A method for retrofitting a roll door lock that enables both manual and remote wireless locking and unlocking of a roll door. More specifically, the retrofitted lock comprises an interior plate with a cylinder lock aperture, a motorhead gear coupled to a motor and rotationally secured within the housing, and a controller functionally coupled to the motor, wherein the controller may be commanded to operate the motor to lock the roll door lock by causing a blocking coupler edge to reduce the diameter of a ball-pin aperture, and unlock the roll door lock by withdrawing the blocking coupler edge.

A smart locker includes electronics to operate a user interface, including a keypad, and to receive user commands via the keypad to lock or unlock the smart locker with an electronic lock. The smart locker also receives primary input power and provides direct charging power and wireless charging power for charging electronic devices. The smart locker also is capable of receiving secondary input power to operate the electronic lock in the absence of the primary input power.

A locking mechanism for a motor is provided. The locking mechanism includes a detent mounted on a shaft coupled to the motor, and a solenoid including an electromagnetic coil, a plunger, and a spring that holds the plunger at an extended state. The plunger engages the detent at the extended state when no voltage is applied, and the spring is configured to exert a predetermined force for the plunger to engage the detent to lock the shaft. The plunger retracts away from the detent to allow rotation of the motor shaft when a voltage is applied to the solenoid.

A system for a closure lock comprises a battery-powered remote module with a lock mechanism for operating the lock, the remote module communicating with a base station coupled to a closure controller, the base station able to send lock control signals to the remote module to operate the lock. The module is arranged to have an operation mode and a non-operation mode, power consumption in the non-operation mode being lower than that in the operation mode, and is further configured to switch between the modes based on instructions from the base station. In the non-operation mode, the module maintains a communication link with the base station based on a pre-established synchronisation protocol.

The invention provides reliability against interference between base station and remote module, whilst greatly limiting the power consumption of the remote module.

The present invention includes various types of open-air display cases for displaying, storing, and/or vending food, beverages, or other products having a movable barrier that can be automatically positioned over an open front or side of such a unit to prevent access to the products therein when temperatures, component failure, lost power supply, or other variables affect the condition of the items stored in the display case, and methods of using such units.

A vertical door latch assembly includes an electro-mechanical lock assembly and a rotatable engagement feature. A controller is in electrical communication with the electro-mechanical lock assembly. The controller is configured to direct the electro-mechanical lock assembly between a locking position with the electro-mechanical lock assembly in locking engagement with the rotatable engagement feature and a non-locking position with the electro-mechanical lock assembly in non-engagement with the rotatable engagement feature.

A vertical door latch assembly includes a bolt that has a catch portion located adjacent a distal end of the bolt. A latch has a retention feature for engaging the catch portion of the bolt. An electro-mechanical locking assembly secures the latch between a locking position preventing movement of the bolt and a non-locking position allowing movement of the bolt. A controller is in electrical communication with the electro-mechanical locking assembly and is configured to direct the electro-mechanical locking assembly between the locking position and the non-locking position.

A locking apparatus for a rollup door, comprising a striker member, latch assembly including a latch, a release lever, a trigger, a cam and a solenoid. The latch assembly may also include a limit switch for detecting when the latch assembly is in an unlocked position. The locking apparatus can be electronically unlocked or it can be unlocked manually by a user by actuating the solenoid which causes the latch to release the locked striker member.

A shutter locking assembly that has a bolt carriage with a bolt slidingly engageable with the bolt carriage and a biasing (actuator) means operatively connected to the bolt member and the bolt carriage. The bolt carriage is inserted into a cavity of a shutter slat, and the action of moving the shutter slat between an up (open) position and a down (locked) position, causing the bolt to be moved between an extended position and a retracted position. When the shutter slat is in a down (locked) position the bolt engages with a bolt receiving opening adjacent to the shutter slat, and when in an up (open position) the bolt is retracted

Provided is an opening/closing device that includes a structure for inhibiting a brake engage part or a lock engage part from touching an object or the like and that prevent the perimeter of a guide rail from becoming thick due to the structure. In an opening/closing device in which a brake engage part is caused to engage with a first engaged part by a close prevention device to put a brake on the closing operation of an opening/closing body, a space adjacent to the horizontal width direction end face of the opening/closing body and continuous in the opening/closing body opening/closing direction is ensured, the space is encompassed in the opening/closing body opening/closing direction by the horizontal width direction end face of the opening/closing body, the guide rail, and the support member, and a detach spot for the first engaged part and the brake engage part is arranged within the space.
