Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

The invention is a sliding latch with a bolt sliding in and out of a primary housing from a closed condition to an open condition on a sled that also slides in the housing. A spring biases the bolt to extend out of the housing to the closed condition. The bolt can be moved to an open condition by an electric motor mounted on the sled that rotates a threaded member to move a nut in a cavity in the bolt that pulls the bolt against the spring bias. The bolt can also be moved to an open condition by a force directly on the bolt against the spring bias. The bolt can also be moved to an open condition by a force pulling on the sled to move the sled and nut so the nut pulls the bolt against the spring bias to an open condition.

A power child lock device includes a rotation driving mechanism, a switch link connected to the rotation driving mechanism so as to be moved vertically by a rotational force of the rotation driving means, an inside handle lever cooperatively connected to an inside handle installed in a door of a vehicle, a release lever connected to a door catch and configured to lock or release the door catch, and a power child lever configured to selectively connect or separate the inside handle lever and the release lever by being moved by the switch link.

Disclosed are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also disclosed are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

A lock including a latch provided at one of a door and a cabinet, and a coupler provided at the other one of the door and the cabinet, the coupler including a housing including a latch insertion hole, an engaging lever including an engaging lever body rotatably provided within the housing, a latch insertion groove having a first end of the latch inserted therein by extending from a first end of the engaging part body, and first, second, third, and fourth projections formed by extending a second end of the engaging lever body.

The invention relates to a lock for a motor vehicle door with: a locking mechanism; an actuating lever assembly which acts upon the locking mechanism; and a drive unit for at least one lever of the actuating lever assembly. The drive unit comprises at least one motor and a bolt which is acted upon by the motor and is provided with a recess for at least one output shaft of the motor.

A drawer slide with lock mechanism has an elongated outer slide member extendably coupled to an inner slide member. A latch arm or pin is fixed to the inner slide member for latching by a lock mechanism fixed to the outer slide member. The lock mechanism uses a latch receiver that rotates with respect to the lock mechanism and is in a travel path of the latch arm. A lever arm rotates with respect to the lock mechanism and is positionable to block rotation of the latch receiver in a locked position to retain the latch arm. A motor drives a cam to position the lever arm to free the latch receiver from the locked position.

An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position.

Disclosed are various embodiments of lock devices, systems, and methods. A lock of the application can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock can be made from an assembly of parts that have locating features that require one way installation/assembly. The lock can include an internal power source capable of driving electronics used to determine handedness of a door.
