An exemplary electric strike includes a housing and a keeper pivotally mounted in the housing. The strike also includes a plunger having an extended position and a retracted position, a cage including an aperture, and a locking element movably seated in the aperture. The locking element is engaged with the plunger, and the plunger is structured to urge the locking element radially outward as the plunger moves from an extended position toward a retracted position. The strike also includes a sleeve, a transmission engaged with the sleeve, and a motor drivingly coupled to the transmission. The sleeve is structured to selectively prevent radially outward movement of the locking element and retraction of the plunger. The strike also includes at least one of a lost motion connection and an anti-tamper mechanism.

A tugger train trailer (1) with a chassis (2) and a transport device (7) is disclosed and configured to hold at least one cargo carrier (LT) having rollers (R), wherein the tugger train trailer (1) is provided with at least one locking means (20) that secure the received cargo carrier (LT) in the transverse direction (Q) of the vehicle of the tugger train trailer (1). The locking means (20) has a locking element (21a; 21b) that can be electro-mechanically actuated between a locked position and an unlocked position, wherein the locking element (21a; 21b) is actuated by a spring device (30) toward the locked position and by means of an electric drive device into the unlocked position.

A lock module for a door in an aircraft has a lock with a blocking element and a non-self-locking drive for moving the blocking element. A blocking sensor detects a blocked position and an unblocked position of the blocking element. A control unit receives a blocking signal from the sensor and activates the drive based on the blocking signals of the blocking sensor(s). A module portion of the door leaf has at least the lock, the drive, and the blocking sensor structurally integrated therein. There is also described a door for the space with a lock module where the door leaf of the door contains the module portion, and a space of an aircraft which is closed by the door.

The subject matter of this specification can be embodied in, among other things, a rotary lock assembly that includes an epicyclic gear assembly that includes a sun gear assembly having a sun gear axial aperture defined therein, a ring gear assembly, and a planet gear assembly mechanically engaged to the sun gear assembly and to the ring gear assembly, a lock motor configured to urge rotation of the sun gear assembly, and a screw lead extending axially through the sun gear axial aperture.

A deadbolt control and security system for preventing rotation of a deadbolt manual egress handle of a deadbolt lock is described herein. The system preferably includes a deadbolt interface unit and at least one actuator unit. The deadbolt interface unit has a manual mode (the deadbolt interface unit manual egress handle controlling locking and unlocking the deadbolt lock) and a remote mode (the at least one actuator unit controlling locking and unlocking the deadbolt lock). The deadbolt interface unit includes: a deadbolt interface unit manual egress handle; a gear train having a shaft coordinated with the deadbolt interface unit manual egress handle; a unit-handle coupler that interfaces between the deadbolt manual egress handle and the deadbolt interface unit manual egress handle via the shaft; and a clutch. Preferred systems prevent the deadbolt lock from being unlocked using keys and/or other bypass tools.

An electronically-controlled manually-actuated deadbolt lock is provided. The electronically-controlled manually-actuated deadbolt lock includes an internal spring-actuated coupling mechanism that, when a user is authenticated, the coupling mechanism is placed in an engaged position that allows a deadbolt latch to be moved into a locked or unlocked position responsive to a manual rotation of a turn piece. Because the deadbolt latch is manually driven, a warped door condition can be overcome. Additionally, because the deadbolt latch is manually actuated, operation of the electronic motor may be decreased, which may increase battery life.

A method for operating a deposit-operated lock system for a borrowed object, in particular for a transport trolley which can be moved by hand. There is also described a suitable deposit-operated lock system. A key that is held in a deposit lock is released when an electric drive drives a carriage that is displaceably mounted on a blocking element in an initial position.

A door latch for an electrical appliance includes a rotary gripper movably disposed between a gripping position and a release position with rotational displaceability and having a gripping mouth delimited between a pair of jaws. The rotary gripper is adapted to hold captive a striker in the gripping mouth for holding closed a door of the electrical appliance in the gripping position and to permit release of the striker for opening the door in the release position. The gripping position and the release position correspond to different rotational positions of the rotary gripper. A spring arrangement in the gripping position of the rotary gripper exerts on the rotary gripper a bias which counteracts a movement of the rotary gripper towards the release position. An opener mechanism for opening the closed door includes a movably arranged opening element separate from the striker and a drive unit for driving the opening element.

An electromechanical lock includes an electromechanical locking mechanism and a control circuit, wherein an associated counter-piece is locked by way of the locking mechanism. The locking mechanism has a latch, an entrainer that is rotatable about an axis of rotation for driving the latch, and an electric motor for driving the entrainer, wherein the latch is moveable between a locking position and an unlocking position, wherein the latch is preloaded in the direction of the locking position. The entrainer is rotatable into a release position, a standby position, and a blocking position and the latch can is driven to perform a movement into the unlocking position by rotating the entrainer into the release position. In the standby position, the latch is released to be urged back against the preload. In the blocking position, the entrainer blocks the latch against a movement in the direction of the unlocking position.

A lock and lid lock for an appliance are provided. The lock has a base supporting a driving mechanism, a sliding mechanism, a connecting mechanism and a locking mechanism. The driving mechanism includes a driving unit that drives rotation of a screw rod. A sliding block is connected to a gear that is engaged with the screw rod and drives the sliding block to move linearly back and forth with the rotation of the screw rod. One end of the connecting mechanism is connected to the sliding block and the other end is connected to the locking mechanism. This allows linear movement of the sliding block to be converted into rotational movement of the locking mechanism. The locking mechanism is rotatably connected to the base and may include a locking portion which is configured to unfold or retract relative to the base along with the rotation of the locking mechanism.
