An appliance includes a hinge module between a main body and a pull-down door. The hinge module includes a housing, a rotational axis member disposed in the housing serving as a center of rotation between the pull-down door and the main body, an inner link housing movably disposed in the housing that moves with the opening of the pull-down door in a direction of the rotational axis member, and a damper installed in the inner link housing, the damper including a piston and a cylinder and providing damping force according to a relative movement of the piston and the cylinder. Any one of the piston and the cylinder of the damper moves with the inner link housing and the other of the piston and the cylinder of the damper moves by a predetermined distance as the inner link housing moves and then is interfered by the housing so as not to move further, and the piston and the cylinder of the damper starts damping, wherein the predetermined distance corresponds to an opening angle of the pull-down door in which the damping is started.

An electric strike lock is disclosed. The electric strike lock cooperates with a lock when in use. The lock has a lock tongue. The electric strike lock includes a base. The base has an opening for accommodating the lock tongue. The base has a pair of grooves corresponding to two opposite sides of the opening. Two sliding members are slidably disposed in the respective grooves. The sliding members are connected with at least one driving unit for the sliding members to slide closer to each other so that the lock tongue is engaged in the opening, or for the sliding members to gradually slide away from each other so that the lock tongue is disengaged from the opening, thereby performing locking and unlocking operations on a door in a sliding manner.

A safety door device according to an aspect includes: a full closing detector for detecting that a safety door has fully closed from an opened state; a locking mechanism for locking the safety door so that the safety door does not open; a measurement unit (acceleration sensor, control unit for measuring a travel acceleration, a travel speed, or a travel time when the safety door closes; and a control unit for controlling the locking mechanism to lock the safety door when the safety door is detected to be fully closed. If the travel acceleration or the travel speed is greater than a first threshold, or if the travel time is shorter than a second threshold, then the control unit does not cause the safety door to be locked.

A locking assembly for a non-pivotable door is provided. The locking assembly comprises a spacer plate defining a spacer plate bolt void and a strike plate defining a strike plate bolt void. The spacer plate and strike plate are to be coupled to one another and further fixedly coupled to the non-pivotable door, such that the spacer plate bolt void and the strike plate bolt void are aligned. The locking assembly further comprises a locking mechanism and a housing, which is configured to receive and contain the locking mechanism. The locking mechanism comprises a latch bolt that is moveable between a retracted position within the housing and a deployed position. In the deployed position, the latch bolt extends outwardly from the housing and into each of the spacer plate bolt void and the strike plate bolt void, thereby locking the non-pivotable door to the housing.

A locking system is installed inside a truck work body such as a service body. A linear actuator drives a sliding member longitudinally between locked and unlocked positions. The sliding member is supported by slide bearings. A spring may bias the sliding member toward the unlocked position. Locking catches are secured on the compartment doors of storage compartments of the truck work body. Locking members protruding from the sliding member engage the locking catches in the locked position, and disengage from the locking catches in the unlocked position. The actuator may be wirelessly activated by a transmitter key fob. The actuator is mounted by tamper-resistant fasteners that are accessible and removable from the exterior of the work body, to release the actuator and unlock the system in the event of an actuator failure. A single actuator locks all compartments on one side of the work body.

An exemplary trim lock device is configured for use with a trim comprising a lift finger, and generally includes a housing, a blocking member, and a lock actuator. The blocking member includes a projection, and is rotatably mounted to the housing for rotation between a blocking position in which the projection blocks actuating movement of the lift finger and an unblocking position in which the blocking member does not block actuating movement of the lift finger. The lock actuator is operable to rotate the blocking member between the blocking position and the unblocking position.

An improved mechanism of electric lock for door, comprising a case, on both side of the opening of the case arranged keeper arms, drive rods, and rotate member, and a drive mechanism connected to a drive member and a brake member; to achieve lock mode, the drive member drive the brake member to be engaged with the rotate member, making the keeper arms and drive rod unable to rotate, so the keeper arms can block the latch bolt from going through the opening; to achieve unlock mode, the drive member drive the brake member to be separate from the rotate member, making the keeper arms and drive rod able to rotate, so the latch bolt is able to go through the opening.

A rim strike assembly includes a strike body, strike jaw, retaining clutch, locking cam, locking clutch, and a solenoid. The strike jaw, retaining clutch, locking cam, and locking clutch are pivotably coupled to the strike body. The strike body and strike jaw define a latch cavity to receive a latch of a door. The strike jaw includes a jaw follower. The strike jaw is pivotable between a release position and a closed position. The retaining clutch engages the jaw follower and includes a retaining follower. The locking cam includes a retaining notch and a locking notch. The retaining follower engages the retaining notch. The locking clutch includes a locking follower that engages the locking notch of the locking cam. The solenoid includes a plunger coupled to the locking clutch such that movement of the plunger rotates the locking clutch from a locked position to an unlocked position.

An actuator-controlled electric strike for operating in conjunction with a spring latch of a lockset is provided. The strike comprises a housing having an entry chamber therein, and a spring latch keeper disposed in the entry chamber for movement between a keeper locked position and a keeper unlocked position. The spring latch keeper includes a keeper face, a second surface recessed from the keeper face and a contact ridge between the keeper face and second surface. The keeper face is contactable by the spring latch when the spring latch keeper is in the keeper locked position. The contact ridge, disposed at a non-perpendicular angle with the rotational axis of the keeper is contactable by the spring latch as the keeper moves toward its unlocked position so that a contact point on said spring latch changes as said spring latch exits said entry chamber.

The electric strike can have a housing having an internal face receivable against a receiving face of a door frame, an external strike face, a socket recessed into the strike face along a socket axis normal to the receiving face of the door frame, for receiving a male locking member retractably mounted to a door, the male locking member also being moveable transversally to the socket axis, along a horizontal escape path, by opening the door, the electric strike further having a keeper pivotally mounted around a pivot axis between a closed configuration and an open configuration, the pivot axis parallel to the socket axis and offset from the escape path on a first side of the socket, inside the housing, the keeper having a gate member forming a restraining wall of the socket blocking the escape path when in the closed configuration, and a distal end.
