A transmission mechanism of an electromechanical lock includes a first rotating wheel and a rotatable structure. The first rotating wheel has a recessed portion and two first protruding portions. The recessed portion is arranged in a center of the first rotating wheel, and the two first protruding portions are separated from each other and protrude from a side surface of the recessed portion. The rotatable structure is arranged in the recessed portion. The rotatable structure includes a rotatable portion and two elastic members. The rotatable portion is rotatably arranged in the recessed portion. The two elastic members are separated from each other and connected to the rotatable portion, in which each of the elastic members has a second protruding portion close to the side surface of the recessed portion and is configured to interfere with each of the first protruding portions.

A dispensing cabinet may include a security panel and a plunger having a disengaged position and an engaged position. The plunger may be secured in the disengaged position by the security panel. The security panel may be released in order to transition the plunger from the disengaged position to the engaged position. The dispensing cabinet may further include a lever configured to interface with the plunger and one or more latch assemblies. The lever may shift upwards in response to the plunger being transitioned from the disengaged position to the engaged position. An upward motion of the lever may release the one or more latch assemblies by rotating, to a limit, a cam bracket included in each of the one or more latch assemblies. The dispensing cabinet may be unlocked by the release of the one or more latch assemblies.

A safe for the storage of a valuable, such as a firearm. The safe has an imaging system that is used to scan a portion of a human in the near infrared spectrum to image blood vessels and determine if the image matches a stored image and thereafter effect unlocking of the safe. A manual override lock system is provided to manually effect unlocking of the safe.

A latching system and method are configured to selectively latch and unlatch a first component in relation to a second component. The latching system and method include an actuator, a first coupler secured to the actuator, a latch, and a second coupler secured to the latch. The first coupler is configured to couple to the second coupler to couple the actuator to the latch. The first coupler is configured to uncouple from the second coupler to uncouple the actuator from the latch in response to the latch being manually operated.

A latch control device includes a connecting seat divided by two integrally formed walls into a hollow portion and a mounting portion spaced from the hollow portion. A detecting module is disposed between the two walls. A locking member is pivotably mounted between the two walls. A first restraining member is disposed in the mounting area and is configured to lock or unlock the locking member, controlling pivotal movement of the locking member. When the locking member is not pivotable, a latch of a door lock in the hollow portion is restrained in the hollow portion, preventing opening of a door to which the door lock is mounted. When the locking member is pivotable, the locking member can pivot while the door pivots, permitting opening of the door.

Systems and methods to indicate whether a safe is locked or unlocked.

A redundant actuation lock apparatus includes an interface, an electronic mechanism, and a manual mechanism. The interface manipulates lock bar(s) into a locked/unlocked position. The electronic mechanism includes an actuator and power drive. The actuator is disengageably coupled to and drives the interface. The power drive is coupled to and drives the actuator in response to a control signal. The manual mechanism includes a key input and an output. The key input receives and rotates with a mechanical key. The output disengageably couples to the interface and rotates with the mechanical key. The actuator is engaged with and the output is disengaged from the interface in an electronic mode, while the actuator is disengaged from and the output is engaged with the interface in a manual mode.

A locking device for an energy storage device of a motor vehicle, includes a locking element, which is adjustable based on a control signal, by an adjusting device between a locking position, in which the locking element engages with a latch receptacle, and a release position, in which the locking element is out of engagement with the latch receptacle. The adjusting device has an adjusting element made of a shape memory alloy. The shape change enables the locking element to be adjustable between the locking position and the release position.

An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

An exemplary trim assembly comprises an escutcheon, a drive spindle, a lock mechanism, a cam mechanism, and a driver. The drive spindle is mounted to the escutcheon for rotation about a longitudinal axis. The lock mechanism includes a lock gear movably mounted in the escutcheon. The cam mechanism includes a first cam defined by the escutcheon and a second cam defined by the lock gear. The driver is operable to rotate the lock gear between a first rotational position and a second rotational position. The cam mechanism is configured to longitudinally drive the lock gear from a first longitudinal position to a second longitudinal position as the lock gear rotates from the first rotational position to the second rotational position. Movement of the lock gear between the first longitudinal position and the second longitudinal position transitions the lock mechanism between a locked state and an unlocked state.
