An electronically-controlled manually-actuated deadbolt lock is provided. The electronically-controlled manually-actuated deadbolt lock includes an internal spring-actuated coupling mechanism that, when a user is authenticated, the coupling mechanism is placed in an engaged position that allows a deadbolt latch to be moved into a locked or unlocked position responsive to a manual rotation of a turn piece. Because the deadbolt latch is manually driven, a warped door condition can be overcome. Additionally, because the deadbolt latch is manually actuated, operation of the electronic motor may be decreased, which may increase battery life.

A modular electronic deadbolt includes a bolt module having a first housing defining a first longitudinal axis, a motor disposed in the first housing, and a deadbolt configured to be linearly moveable in relation to the first housing along the first longitudinal axis by the motor. The modular electronic deadbolt also includes a battery module configured to be operatively coupled to the bolt module. The battery module includes a second housing configured to receive a power source, and a face plate coupled to the second housing. The faceplate defines a second longitudinal axis and includes an extension that extends along the second longitudinal axis. The extension is configured to removably couple the bolt module to the battery module such that the first longitudinal axis is substantially orthogonal to the second longitudinal axis.

A flap opening and closing mechanism includes a flap and a lock member. The flap includes a first engagement member, and is pivotally supported on a vehicle body side. The flap opens and closes an opening in an outer plate of a vehicle body. The lock member locks the flap. The lock member includes a body to be mounted on the vehicle body side, a swing member pivotally supported on the body, a second engagement member, and an adjustor. The second engagement member is engaged with the first engagement member, and provided in the swing member. The adjustor allows for a rotational movement of the body about a rotation shaft of the swing member to the vehicle body in a state where the body is temporarily fixed to the vehicle body side. The lock member locks the swing member at a position corresponding to the closing position of the flap.

Various disclosed embodiments include a lock assembly. The lock assembly includes a lock bolt. The lock bolt has a lock bolt body and having a bolt security engagement feature formed as part of the lock bolt body. The lock assembly also includes a receiver. The receiver has a receiving area for receiving at least a portion of the lock bolt and the receiver has a receiver security engagement feature formed as part of the receiver. The receiver security engagement feature is complementary to the lock bolt security engagement feature.

A method for operating a deposit-operated lock system for a borrowed object, in particular for a transport trolley which can be moved by hand. There is also described a suitable deposit-operated lock system. A key that is held in a deposit lock is released when an electric drive drives a carriage that is displaceably mounted on a blocking element in an initial position.

A latch control device includes a connecting seat divided by two integrally formed walls into a hollow portion and a mounting portion spaced from the hollow portion. A detecting module is disposed between the two walls. A locking member is pivotably mounted between the two walls. A first restraining member is disposed in the mounting area and is configured to lock or unlock the locking member, controlling pivotal movement of the locking member. When the locking member is not pivotable, a latch of a door lock in the hollow portion is restrained in the hollow portion, preventing opening of a door to which the door lock is mounted. When the locking member is pivotable, the locking member can pivot while the door pivots, permitting opening of the door.

An exemplary apparatus includes a housing, a lock mechanism mounted to the housing, an electromechanical driver, a first override mechanism, and a second override mechanism. The electromechanical driver is mounted to the housing and is operable to unlock the lock mechanism. The first override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The second override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The apparatus has a first configuration in which a lock cylinder is engaged with the first override mechanism such that actuation of the lock cylinder unlocks the lock mechanism. The apparatus has a second configuration in which the lock cylinder is engaged with the second override mechanism such that actuation of the lock cylinder unlocks the lock mechanism.

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.

Methods and systems for detecting and correcting insufficient locking behavior, using an electronic lockset. One aspect is a method of deadlatching an electronic lockset, the method comprising detecting motion of a deadbolt from an unlocked position toward a locked position, determining a position of the deadbolt after the motion ceases via a sensor of the electronic lockset, determining, based on the position, whether the deadbolt has moved to the locked position, wherein in the locked position the deadbolt is placed in a deadlatched state, and transmitting an actuation command to the electronic lockset to move the deadbolt into the locked position.

A locking device intended to prevent opening of a door/doors includes a body, which is capable of being coupled immovably to a door handle and prevents opening of a door/doors. The body is provided with a coupling arrangement adjustable with adjustment elements for locking the handle against an external surface of the door by being propped immovably on a vertical frame member of the door or on a handle of the adjacent door.
