The invention discloses a bed cover connection device for pickup truck, wherein includes a sidebar lock system connected to two sidebars, a large rear bar lock system connected to the rear bar and multiple intermediate node blocks, the sidebar locking system includes a sidebar lock base, the sidebar lock base has a locking cavity, and there are two large rear bar lock systems, the two large rear-bar lock systems are set corresponding to the two side-bar lock systems, the large rear-bar lock system includes a rear-bar lock block and a lock connection shaft, the rear-bar lock block is connected to the rear bar, the lock connection shaft passes through the rear-bar lock block. The device in this invention can pull the lock out of the lock cavity to open the rear bar by setting up a wire rope, and multiple intermediate node blocks, which separate the wire rope into multiple segments, are set up to facilitate the user to pull the wire rope.

A magnetic door lock control system for use with an egress handle system and a door is provided. The magnetic door lock control system employs magnets that communicate with one another across the door jamb thereby eliminating the need for a hard wired electrical connection between the egress handle system (e.g., a mechanical switch bar) configured with a door and a door locking mechanism mounted above the door in the header of the entranceway. In this way, the need for an electrical wire loop between the egress handles and the door locking mechanism is eliminated.

The present invention relates generally to the field of cabinet locks. More specifically, the present invention relates to a cabinet lock device primarily comprised of a pendulum housing, a latch housing, a catch housing release, and a door plate that can be attached to a rear door surface of a cabinet door. The door plate further receives the catch housing release. The pendulum and latch housing is further comprised of a latch and a pendulum wherein the pendulum activates a series of internal mechanisms within the pendulum and latch housing when movement of the cabinet is detected, which ultimately releases the latch into the catch housing release such that the cabinet door automatically locks in an automatic fashion. The catch housing release is further comprised of a release lever that can be used to unlock the cabinet from the outside after the device has been locked.

A vibration-reducing apparatus for an assembly comprising a first member including a latch and a second member including a striker may include a threaded post having arm members extending outwardly therefrom, the threaded post being rotatably advanceable in discrete increments in a threaded opening extending through the first member such that, in a closed position of the first and second members, a distal portion of the threaded post extending through the first member contacts the second member upon rotational advancement of the threaded post in the threaded opening; and a locking region arranged to interact with at least a portion of the arm members, the rotational advancement of the threaded post in the threaded opening and contact with the second member reducing an engagement distance between the latch and the striker with the first and second members in the closed position, and attenuating vibrations between the latch and the striker.

A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

A latch includes a base having a bore extending therethrough defining an axis, a plunger positioned within the bore and rotatable about the axis, a drive shaft positioned adjacent the base and engaged with the plunger such that rotation of the plunger about the axis causes corresponding rotation of the drive shaft about the axis, a bracket positioned adjacent the base and the drive shaft and engaged with the drive shaft such that rotation of the drive shaft about the axis causes movement of the bracket, and a closure element coupled to the bracket such that movement of the bracket causes the closure element to move between a position wherein the closure element allows a structure to move with respect to an adjacent structure and a position in which the closure element prevents the structure from moving with respect to the adjacent structure.

A lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in at least a closed orientation and an open orientation. The latching assembly further includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions.

This cylinder lock is a cylinder lock which can lock and unlock a mortise lock via a displacement transmission member. The cylinder lock comprises: a cylinder lock body; a key insertion part which is provided on one end side of the cylinder lock body and into which a key is inserted; and a displacement transmission member mounting part which is provided on the other end side of the cylinder lock body and on which the displacement transmission member can be mounted. A plurality of displacement transmission members corresponding to each of case locks having a plurality of specifications can be removably mounted on the displacement transmission member mounting part. Thus, cylinder locks having the same specification can be applied to case locks having a variety of specifications.
