This document discloses a storage device for theft-proof storage of valuable articles, comprising a cabinet, having at least one drawer space, a safe drawer, which is received in the drawer space, a safe housing, comprising side walls and a top wall connecting the side walls, wherein the safe drawer is slidably connected to the safe housing and wherein the safe housing is mounted to the cabinet in the drawer space, a locking member, which is movably connected to the safe drawer or to the safe housing, an actuator, which is operatively connected to the locking member, for controlling a movement of the locking member, and a controller, which is operatively connected to the actuator, and which is configured to control the actuator. The controller is configured for receiving a control signal, based on which the controller is configured to control the actuator. The locking member is movable between a first position, in which the locking member locks safe drawer relative to the cabinet, and a second position, wherein the safe drawer is unlocked relative to the cabinet.

A rotary latch mechanism for releasably securing a first structure relative to a second structure. The rotary latch mechanism includes a housing adapted to be attached to the first structure, an actuator assembly coupled to the housing, a linkage coupled to the actuator assembly and arranged for movement along the housing with movement of the actuator assembly, and a bolt coupled to the housing and to the linkage, the bolt arranged for pivotal movement relative to the housing with movement of the linkage. The bolt is adapted to move between a latched position engaged with the second structure to secure the first structure relative to the second structure and an unlatched position spaced apart from the second structure to allow movement of the first structure relative to the second structure.

An interconnection assembly includes a chassis, and cam plates that are rotatably coupled to the chassis to pivot about a plurality of rotational axises. An upper cam plate is operatively coupled to a deadbolt. The upper cam plate has a cam surface. A lower cam plate is rotatably coupled to the chassis to pivot about a second rotational axis. The lower cam plate is operatively coupled to an interior latch bolt handle. The lower cam plate has a cam slot. A linkage bar is rotatably coupled to the chassis to pivot about a pivot axis. The linkage bar has a first linkage portion having a first cam follower configured to operatively engage the cam surface of the upper cam plate and has a second linkage portion having a second cam follower operatively received in the cam slot of the lower cam plate.

A sliding panel deadbolt lock assembly that is associated with a sliding panel that transitions between an open position and a closed position relative to a stationary panel that is coupled to the sliding panel. A sliding panel lock assembly includes a pin that transitions between an engaged position and a retracted position. A first magnetic field sensing device is positioned at the retracted position of the pin when the pin is in the retracted position to enable the sliding panel to transition from the closed position. The first magnetic field sensing device detects a magnetic field generated by a first magnetic field generating device positioned on the pin. The first magnetic field sensing device positioned at the retracted position of the pin is aligned with the first magnetic field generating device positioned on the pin when the pin is in the retracted position.

An intelligent door lock system is coupled to a door at a dwelling. A first sensor is at the dwelling. The first sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. The lock device is coupled to the first sensor and the lock device includes a bolt. An engine, an energy source and a memory are coupled together. A magnetic sensor provides a reading or measurement used to determine a door open or closed status.

An access door arrangement of an elevator shaft, wherein at least one elevator car is moving, includes a door lock, whereby in connection with the door lock a reset switch of an inspection mode resetting device is located, whereby the door lock has a lock part movable between a lock position and an open position and whereby the reset switch is integrated in said door lock to be operated by the movement of the movable lock part or a related movable part. This solution allows an easy resetting of the inspection mode of the elevator.
