A clutch for a door lock may comprise an output shaft configured to operate the door lock, and a thumb turn shaft coupled to the output shaft comprising an inclined projection. The clutch may also comprise an input gear configured to be coupled to an actuator output, and a coupler coupled to the input gear such that the coupler and input gear rotate together. The coupler may be configured to translate between an engaged position and a disengaged position, where the inclined projection of the thumb turn shaft is configured to move the coupler from the disengaged position to the engaged position when the thumb turn shaft rotates relative to the coupler. In the disengaged position the coupler may be decoupled from the output shaft.

Gearbox clutch mechanism for motorized lock

Keypad for a door lock

A lock having a latch assembly with a bolt head freely movable between an extended position and a retracted position. The latch assembly also includes lock pin that is movable between a locked position and an unlocked position, which may be moveable by a motor and/or biasing mechanism. The lock also has a strike assembly including a strike housing for receiving the bolt head. The strike housing includes a keeper biased to a latched position relative to the bolt head. When the lock pin is in the locked position, the lock pin engages the keeper to hold the keeper in the latched position, and thus the bolt head in the extended position in the strike housing. The lock also includes an access control system for controlling the motor of the lock.

Embodiments described herein relate to a motorized door lock detection system. Some embodiments of the device include a sensor gear that meshes directly with the gear system of the motorized door lock. As the sensor gear rotates, it drives the rotating contact of a potentiometer, varying the voltage in a reference circuit that corresponds directly with an angular position of the thumb-drive used to drive the deadbolt. In some embodiments, a conducting member that rotates with the output shaft of the deadbolt contacts a plurality of electrical contacts positioned such that they are contacted when the deadbolt is in a position range that requires more precise position monitoring. When the conducting member is in contact with a deadbolt, power is supplied such the output from the potentiometer can be determined. In this way, power to the potentiometer and/or controller driving the potentiometer can be limited.

Deadbolt position sensor

A progressive deadlatching arrangement for a deadbolt lock prevents an external force applied on the deadbolt from retracting the deadbolt or otherwise compromising a secured door. The progressive deadlatching arrangement prevents external forces from retracting the deadbolt while still allowing an authorized user to operate the deadbolt. ASSA ABLOY Residential Group, Inc. is a subsidiary of ASSA ABLOY AB.

Progressive deadlatching for deadbolts

A locking mechanism for a bored lock has a lock chassis, a locking element, a motor housing, a reversible electric motor, an auger, and a spiral lock spring disposed between the locking element and the motor. The motor may drive the auger in a first or second rotational direction to move the spring towards/away from the motor to reduce/increase spring force on the locking element, thereby moving the locking element to an unlocked/locked position. One of the locking element and motor housing has a projection while the other has a guideway for slideably receiving the projection. The guideway prevents rotation of the locking element with respect to the motor as it moves between locked and unlocked positions. The projection and guideway are interlocked to prevent disassembly of the locking element and motor housing.

Locking mechanism for bored lock

An electronic lock housing for the inside surface of a door with an opening therethrough has an interior portion for receiving electronic components for a door lock, a back portion with channels, a bracket, a plug, and a front portion. The back portion is meant for securing onto the door surface and has an opening meant for alignment with the door opening. The channels in the back portion permit air from the outside of the door to flow through the door opening and housing back opening to the inside of the door without passing through the housing interior. The bracket secures the back portion to the door and receives the plug to create an air-tight seal within the housing interior. The housing front portion is secured over the assembled back portion, bracket, and plug once they are installed to the door surface, fully encasing the electronic components.

Channel gasket and plug for electromechanical lock

A gasket system for an electromechanical locking device includes an inner gasket for the door facing surface of the device. The peripheral edge of the inner gasket and the peripheral edge of the housing of the device include complementary step features that interact to compress the peripheral edge of the inner gasket to seal the housing and mitigate air and water flow into the locking device. Some embodiments of the device include an 'L' shaped front gasket that is compressed between stepped features of two portions of the housing to further mitigate air and water flow. Openings in the gaskets for lock components are circumferentially surrounded by compressible ribs that extend from the surface of the gasket. The compressible ribs are compressed against the surface of the door preventing air and water from migrating through openings.
