A door strike assembly includes a strike housing and latch release assembly. The door strike assembly is used in conjunction with a lockset which includes a door latch moveable from a latched condition when a door is closed and an unlatched condition where the door may be opened. The lockset includes a deadlatch to prevent unauthorized movement of the door latch when the door is closed. The latch release assembly is received within the strike housing and includes a latch ejector which engages the deadlatch when the door is closed. A motor is coupled to the latch ejector where actuation of the motor rotates the latch ejector to disengage the latch ejector from the deadlatch. Further rotation of the latch ejector causes the latch ejector to engage the door latch to move the door latch to the unlatched condition such that the door may be opened.

An electric locking device for an operable/closable member attached to an opening portion, includes a biasing member which biases a pair of rods in a direction in which the rods are brought into engagement with a pair of locking portions, an actuator for sliding the rods to disengage from the locking portions, the actuator having a case having an opening portion, a motor disposed within the case, a worm rotated by the motor and a worm wheel supported rotatably on the case and interlocked with the worm for rotation. The worm wheel has a rotating portion projecting outwards of the case from the opening portion, and proximal end portions of the rods are assembled individually to the rotating portion so as to move in an associated fashion, causing the rods to slide in a synchronized fashion in opposite directions to each other.

A gear assembly includes a planetary gear set and a clutch. The planetary gear set includes a sun gear, at least one planet gear meshing with the sun gear, a carrier supporting the at least one planet gear, and an outer ring gear meshing with the at least one planet gear. The clutch is operable to engage with and disengage from the planetary gear set to enable the planetary gear set to switch between a first mode and a second mode.

A switch device includes a moving unit, a manual unit, a plurality of securing members and an actuating mechanism. The moving unit includes a ring gear, first and second sliding members, and a first connecting member. The first and second sliding members are slidable relative to the ring gear and respectively in mutually perpendicular directions. The securing members extend through the first connecting member and the first sliding member into the manual unit for securing the first sliding member between the first connecting member and the manual unit. The actuating mechanism is co-movably connected to the second sliding member and is adapted for actuating operation of a lock mechanism.

An intelligent door lock system for a door at a dwelling. The intelligent door lock system includes a door status device is at the dwelling, an engine, an energy source, a memory, and a camera. 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. The engine, the energy source, and the memory are coupled together. The camera is configured to record in response to door lock status.

An intelligent door lock system is provided with a push notification. A sensor is configured to be coupled to a drive shaft of a lock. The position sensing device senses position of the drive shaft to assist in locking and unlocking a lock of a lock. An engine with a memory is coupled to the positioning sensing device. The engine and an energy source are coupled to the circuit. A push notification is provided to a dwelling user when a lock of the intelligent door lock system is manually opened.

A system allows dwelling access to third parties. An intelligent door lock system at the dwelling includes a device configured to be coupled to a drive shaft of a lock device, with the device sensing movement of the drive shaft to assist in locking and unlocking a lock of a lock device. The intelligent door lock system is configured to be in communication with a server. An occupant/or owner, or end-dwelling user of the dwelling communicates with the server to grant a third party secured access to a dwelling, which can be programmatic.

A present invention relates to a digital doorlock including a latch bolt self-loosening structure which includes an authenticator which receives an authentication signal and performs authentication; a motor which is driven in a predetermined direction when authentication is performed by the authenticator; a latch operator which can be operated through driving of the motor; and a shaft which is rotated according to operation of the latch operator and operates a latch bolt, wherein the latch operator releases the latch bolt by operating according to the authentication and rotating the shaft in one direction.
