An intelligent door lock system coupled to a door at a dwelling. a door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

An energizable electromagnet of a door locking system is affixed to the door or the door frame for electromagnetically attracting an armature affixed to the other. A power control circuit is configured to selectively energize the electromagnet using a pulse-width modulated current cycle wherein two levels of magnetic force may be selectively applied to the system. A door position sensor is configured to provide a first communication signal to the power control circuit when the door is in a closed position. A second communication signal is provided when the door is not in the closed position. The electromagnet is energized at the lower level of magnetic force when the power control circuit receives the first communication signal and at the higher level of magnetic force only when an unauthorized attempt to open the door is initiated.

A latch control device includes a mounting seat and a locking cap device pivotably mounted to the mounting seat and pivotable relative to the mounting seat between a closure position and a non-closure position. Optionally mounted to the latch control device are a first accessory, a second accessory, a third accessory, a first escutcheon, and a second escutcheon. The latch control device is selectively assembled into a first mode (including a detecting device), a second mode (including the detecting device, the first accessory, and the third accessory), or a third mode (including the detecting device, the first accessory, and the second accessory) for cooperating with a cylindrical latch device, a first box type latch device, or a second box type latch device.

A playpen door, including a door frame; a door body movably mounted on the door frame; and a detection assembly mounted on the door frame and the door body and configured to detect open or closed state of the door body. The door body is hinged to the door frame. A locking assembly is arranged between the door body and the door frame. The locking assembly may be opened by a switch. The detection assembly is mounted away from a position where the door body is hinged to the door frame. When the door body rotates relative to the door frame, the detection assembly may be triggered, at which time the door body may be sensed to be open. When the door body returns to the closed position again after opening, the detection assembly may be triggered, at which time the door body may be sensed to be closed.

Locking device having a guard lock for safety doors, comprising a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart, which housing comprises a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor, wherein the actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing, being shaped as a bushing and carrying radially displaceable and fixable engagement elements which lock the engagement plunger at its inner contour in the locked position during a defined state, for which purpose the engagement plunger comprises an engagement stop at the inner contour which acts in the longitudinal direction.

A door system comprises a door frame adapted to be mounted within an opening, a door pivotally attached to the door frame, an AC/DC converter operably associated with the door frame, a DC electric device mounted to the door, at least one sensor mounted to the door frame or the door, and a power management controller configured to receive an input from the at least one sensor and send a command to the DC electric device. The AC/DC converter is configured to be electrically connected to an AC power unit disposed outside the door system. The DC electric device is electrically connected to the AC/DC converter.

Locking device is disclosed for parcel boxes or lockers. The device comprises a user operable handle and a lock mechanism comprising a motor to rotate a pinion to move a rack attached to a handle-blocker and to a deadbolt. The handle-blocker controls transition of the user operable handle between open and closed positions due to movement of the rack, and simultaneously the deadbolt is configured to move between locking and unlocking positions. In the closed position, the handle-blocker and the handle-body have a linear connection with each other and in open position this connection is lost. The handle may be activated by tapping the handle-cover, or by using an RFID, NFC or by mobile technologies. A method to operate opening and closing a parcel box locked with the locking device allows one or more users to access the parcel box via software application paired with the device.

The present invention relates to a door-lock system (S) for a household appliance, in which said household appliance is of the type comprising a frame and a door hinged to said frame, and in which said lock-door system (S) comprises: an engaging member (2), which can be fixed to said door of said household appliance, and comprising a prong (22) and a security member (23) arranged substantially parallel to said prong (22); and a door lock device (1).

The present invention also relates to an oven.

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.

An electronic gaming machine including a cabinet defining an interior space. The electronic gaming machine also includes a door releasably fastened to the cabinet operable to move between a locked state preventing access to the interior space and an unlocked state permitting access to at least a portion of the interior space. A security housing comprising a locking assembly and an optical switch coupled to a processor. The locking assembly includes an actuator defining a channel. The optical switch comprises a transmitter and a receiver. When the door engages the locking assembly, the actuator is operable to move the channel to align with the transmitter and the receiver to form an optical path between the transmitter and the receiver through the channel and the optical switch is operable to communicate the locked state to at least one of the processor, the server computer, and the gaming system.
