An electric strike having two keepers arranged to pivot about respective shafts extending in a longitudinal direction, a lock lever for locking the keepers in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever. The keepers form side walls of a bolt cavity and are arranged to pivot between a door-locking position and a door-releasing position. Therefore, the bolt may exit the cavity in two directions, e.g., a first direction for a left-handed closure member and a second direction for a right-handed closure member. The strike can thus be mounted in the same orientation for both left-handed and right-handed closure members.

A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation to a main latch, wherein the latch slider is provided with a protruding lug; a lock arrangement comprising; a body moving between a locking position and an unlocking position, wherein in the locking position a portion of the body is preventing movement of the lug along a path in parallel with said first axis, and in the unlocking position the lug can be moved along said first axis; and an electrically powered device connected to the body for moving the body between the locking position and the unlocking position.

A self-locking parcel delivery apparatus and method includes a tamper-resistant compartment beneath a lid of a porch bench seat and insulated for protecting delivered parcels. The apparatus includes a lid that is held open magnetically until proactively released to close and lock (such as by a delivery person) or by a remote user via a primary software application running on a mobile communications device. The apparatus may be operated in conjunction or cooperation with a supplemental software application associated with a video motion detection system so that a remote user can authenticate a supposed delivery person and then, using another software app, activate a remote delivery container to be made ready to receive a delivered parcel.

An electric strike having a keeper arranged to pivot about a shaft extending in a longitudinal direction, a lock lever for locking the keeper in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever. The strike is provided with a bearing element arranged to bear against the lock lever. The bearing element acts as a stop against possible lateral motions of the lock lever. Such motions may be induced by trying to force open the door lock when the lock lever is in the locking position. By providing the bearing element, it is avoided that the forces due to these lateral motions are exerted onto the second shaft that connects the lock lever to the strike.

A door latch for a domestic electrical appliance wherein the door latch comprises a rotary gripper which, on closing of a door, can be transferred from a release position into a gripping position by rotation in a rotational plane, and an electrically controllable locking mechanism having a movably arranged blocking element which, in the gripping position of the rotary gripper, can be fixed in a blocking position in which the blocking element cooperates with the rotary gripper to block the movement of the rotary gripper both from the gripping position into the release position and from the gripping position into a yielding position. The rotary gripper forms a gripping mouth which in the gripping position is oriented to hold captive a closing shackle which, on closing of the door, moves relatively closer to the rotary gripper along a closing path and arranged for a yielding movement into the yielding position.

A control device for a push bar latch, comprising: a base frame having a sliding slot; a control connecting rod, the outer end is combined with an unlocking return unit of the push bar latch and the inner end has a positioning pin, the positioning pin is set through the sliding slot; a locking hook, the outer end has a hook portion relative to the positioning pin; an electromagnet, used for holding the inner end section of the locking hook, so let the hook portion enter a hooking state for the positioning pin; and a release element, used to release the hook portion from the hooking state for the positioning pin when the electromagnet is powered off. Whereby the push bar latch has the enter control function.

An arrangement (10, 82) for locking and unlocking a lock device (58, 74), the arrangement (10, 82) comprising a transfer element (12) movable between a protruded position (42) and a retracted position (56); a core member (14) of soft magnetic material, the core member (14) comprising a coil section (20); an electric coil (16) wound around the coil section (20); and a blocking member (48) comprising a magnet (18), the blocking member (48) being movable between a blocking position (50), in which the magnet (18) establishes a magnetic circuit through the coil section (20) and the blocking member (48) blocks movement of the transfer element (12) to the retracted position (56), and an unblocking position (54), in which the magnet (18) establishes a magnetic circuit through the coil section (20) and the blocking member (48) unblocks movement of the transfer element (12) to the retracted position (56). A lock device (58, 74) comprising an arrangement (10, 82), and a method of controlling a lock device (58, 74), are also provided.

The present disclosure discloses a portable dismantling structure for a smart doorbell, including a doorbell main body; the doorbell main body is provided with a front shell and a cover plate; the front shell is provided with a main control panel and an unlock mechanism; the main control panel is connected to the unlock mechanism in a control manner; the unlock mechanism is provided with a first elastic clasp; and the cover plate is provided with a second elastic clasp matched with the first elastic clasp. To achieve locking, the second elastic clasp of the cover plate is pushed into the front shell to fasten the second elastic clasp with the first elastic clasp to achieve fastened locking of the cover plate and the front shell.

An electronic article surveillance tag including a tag body member and a connecting member having a pin portion releasably engageable with the tag body member, wherein the pin portion extends along a first axis. The tag further includes a locking member having a clutch mechanism including a plunger member formed from a non-ferromagnetic material and an unlocking member connected to the clutch mechanism. The unlocking member is moveable along a second axis perpendicular to the first axis between a locked position and an unlocked position, wherein during movement between the locked position and the unlocked position, the unlocking member moves the clutch mechanism between the first position corresponding to the locked state and the second position corresponding to the unlocked state.

A method for managing the unlocking mode of an object. The object includes a communication interface for communicating with a device for transmitting electromagnetic signals when the object is located in the field of electromagnetic coverage formed by the signals transmitted from the device, and when the object is located in the region of coverage associated with the field of electromagnetic coverage, the method includes selecting a first unlocking mode associated with the region of coverage associated with the field of electromagnetic coverage.
