Abstract: A latch structure comprising an elastic pull latch is disclosed. The top of the elastic pull latch includes a latch bar configured with a latch groove. The elastic pull latch also includes an elastic boss that moves in and out of the latch cover of the pull latch. On both sides of a box, an elastic pull latch is provided at the top and a catch groove having a catch affixed to the lower edge is provided at the bottom. When two boxes are stacked together, the catch in the catch groove of the upper box is snapped into the latch groove of the elastic pull latch of the lower box to securely connect the two boxes. When the latch is released, the catch of the upper box blocks the elastic boss of the latch of the lower box to prevent the latch from retracting inwards.

Abstract: A latch structure according to an embodiment includes a body, a locking body, a latch head, a plunger, and a latch stopper. The body is disposed inside a door. The locking body moves in response to an external operation. The latch head protrudes from the body to maintain the door in a closed position, and rotates when the locking body is spaced apart at least a predetermined distance. The plunger retracts into the body to prevent the latch head from rotating while the door is being closed. The latch stopper prevents the protruding latch head from retracting into the body when the plunger is maintained within the body.

The door has a door frame with four adjustable concealed striker receivers within the door frame. The door has four interconnected concealed mortised bolt lock assemblies, each with a biased bolt, wherein one of the bolt lock assemblies has an engageable brake to hold all four interconnected biased bolts in retraction when the door is opened after a handle interconnected with the four biased blots is moved to a door open position. A roller assembly is provided in the one bolt lock assembly biased to extend and move out from the door when the door is opened and releases the brake and allows the biased bolts to extend and move into the strike receivers when the extended roller assembly is moved inwardly toward the door.

Abstract: An exemplary method generally relates to operating an access control device including a motor, a locking member, and a target component operably connected with the locking member. The motor may be operated to drive the locking member in a first direction from an initial position toward a desired position. When the locking member is blocked from moving beyond a blockage position, a target location of the target component is detected. The motor may then be operated to drive the locking member in a second direction opposite the first direction. The motor may then be operated to drive the locking member in the first direction toward the blockage position while monitoring the location of the target component. As the target component reaches the target location, the motor is supplied with a boost current to drive the locking member beyond the blockage position and toward the desired position.

Abstract: An anti-unlocked mechanism comprises a transmission gear, a sliding rod, a locking member and a first elastic member. The transmission gear includes an arc surface. An end of the sliding rod contacts the deadbolt of the lock body. The sliding rod is provided with a fixed stopper and a second elastic member. When the deadbolt is retracted, the sliding rod moves with the deadbolt against the elastic force of the second elastic member. When the deadbolt extends, the locking member moves with the sliding rod to block the rotation of the rotating part. The first elastic member comprises first and second protrusions. The second protrusion will not hinder the fixed stopper of the slide rod unless the first protrusion contacts with the circular arc surface, which will block the movement of the locking member to block rotation of the rotating part.

Abstract: A door lock for a domestic electrical appliance includes a locking member which is electrically switchable between an unlocking position and a locking position, which locking member in the unlocking position allows a closed door of the domestic appliance to be opened and in the locking position is in blocking engagement with a blockable component at least when the door is closed, and an auxiliary member, separate from the blockable component, which is movable in dependence on the closing of the door from a release position into a blocking position. The blocking engagement effects blocking of the closed door against opening. In the release position, the auxiliary member allows the locking member to be transferred from the unlocking position into the locking position; in contrast, in its blocking position, the auxiliary member blocks the locking member against being transferred from the unlocking position into the locking position.

Abstract: A hatch lock cover includes inner and outer flanges, with a keeper and a handle positioned between the flanges. The handle is rotatable with respect to the flanges to move a batten bar contacting surface into and out of engagement with a batten bar or a hatch cover tab of a hatch cover. A downwardly extending portion of an arm of the keeper may define an aperture and/or include a projection for securing an adjustment plate or extension piece to the arm to provide an alternative batten bar contacting surface. Alternatively, a mounting bracket may be provided to secure the hatch cover lock to a railcar, with the mounting bracket accommodating the hatch cover lock in different positions having different elevations. Such configurations allow the hatch cover lock to be adjusted for use with a batten bar or hatch cover tab having a gasket that has become worn out.
