An example lock apparatus generally includes a housing, a latch spindle, a drive spindle, an electronic lock mechanism, and an override mechanism. The latch spindle is mounted for rotation relative to the housing, and is operable to actuate a latch mechanism. The drive spindle is mounted for rotation relative to the housing. The electronic lock mechanism is disposed in the housing, and is operable to selectively couple the drive spindle with the latch spindle. The override mechanism is disposed in the drive spindle, and is operable to selectively couple the drive spindle with the latch spindle.

A deadbolt lock assembly comprising a retractable and extendable deadbolt, a housing, an outside member movably mounted on the housing, the member being normally disconnected from the deadbolt, and an operator input device on the housing, the device connecting the member to the deadbolt in response to presentation of an appropriate credential, such that a force applied to the member by the operator is mechanically transmitted to the deadbolt to move the deadbolt.

An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position.

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.

Provided is a lock mechanism, wherein the lock mechanism includes a lock base, the lock base is provided with an opening and a cavity extending from the opening, the opening is used for the lock shaft mounted to the battery pack to enter the cavity, the lock mechanism further includes: a lock assembly, the lock assembly is connected to one side of the lock base opposite the lock shaft, the lock assembly is moveable relative to the lock base, and the side of the lock base opposite the lock shaft extends into the cavity or exits the cavity; wherein, the lock assembly is capable of preventing the lock shaft from exiting the cavity from the opening when the lock assembly extends into the cavity; the lock assembly is capable of allowing the lock shaft to exit the cavity from the opening when the lock assembly exits the cavity.

An electronic lock includes a latch member and a clutch mechanism mounted on the outside of the lock cylinder and including a clutch unit, a driving unit and a control module. The clutch unit includes a rotatable seat having a first engaging portion, an accessible knob, and a clutch seat having a second engaging portion. The clutch seat is movable relative to the rotatable seat between an unlock position and a lock position, where the second engaging portion engages and disengages the first engaging portion, respectively.

The invention relates to an electronic lock that defines an open position and a closed position and includes a mobile carriage moveable in a linear manner. The mobile carriage is coupled to a closure element and to an actuation mechanism. A first spring is provided between the mobile carriage and the closure element and is configured to move in relation to the mobile carriage. A lock sensor is provided for controlling the position of the closure element. An electronic control module is connected to the sensor for identifying non-authorised manipulations of the lock when it should be closed. The lock sensor detects when the closure element is in the open position or, if it should be open, the lock sensor does not detect when the closure element is in the open position.

A locking device including: a locking pin movable in a linear direction; a tappet movable in the linear direction; and a clamping device connecting the tappet to the locking pin. Wherein the clamping device having an inner spring and an outer spring arranged coaxially relative to each other in the linear direction, and the inner spring is at least partially surrounded by the outer spring in a radial direction orthogonal to the linear direction.

An electronic lock with an electronic sensing arrangement to accurately sense relative positions of a bolt which mechanically locks a door, such as a door of an electronic drop safe, and to also sense an electronically controlled plunger which locks the bolt in place. The arrangement provides a mechanism for sensing a variety of mechanical malfunctions, as well as, potential fraud or tampering situations.

An interlock unit for preventing rotation from a closed position of a cover to an open position thereof, includes: a hollow case having a rectangular parallelepiped shape disposed at a position adjacent to an inner side surface of a casing, below an end part opposite to a support shaft at the closed position of the cover; an action member that is provided on an upper surface of the case, supported to be movable between a non-operating position and an operating position, and engaged with a protruding part provided on the cover at the operating position to inhibit the cover from rotating toward the open position; electromagnetic drive means provided below the action member to drive the action member; and drive connecting means for driving the action member by connecting the action member and the electromagnetic drive means and transmitting an operation of the electromagnetic drive means to the action member.
