A locking piece assembly adapted for installation in a cylindrical lock and meant to engage a locking mechanism comprises a locking piece and a lock button. The locking piece has one end adapted to engage the locking mechanism and an opposite end with a connecting hook. The lock button has an aperture adapted for attachment to the locking piece connecting hook, and can be depressed to move the locking piece inward to engage the locking mechanism after the locking piece assembly is installed in the cylindrical lock. The lock button can be installed onto the locking piece by hand, specifically by inserting the connecting hook into the aperture on the lock button, pivoting the lock button with respect to the locking piece, and placing the locking piece and lock button into alignment. After installation, the connecting hook is held in place to prevent separation from the lock button aperture.

The present disclosure relates to a refrigerator including a latch device configured to couple or separate the second door to or from the first door, wherein the latch device includes a fixing member disposed on the first door, a locking member provided on the second door to be coupled or separated from the fixing member, and an input member provided on the second door to be rotatable in the left and right directions, and wherein the locking member rotates in a direction of being separated from the fixing member when the input member rotates in the left direction, and the locking member rotates in the direction of being separated from the fixing member when the input member rotates in the right direction.

A window vent stop for use in a sliding sash window or a sliding sash door assembly. The vent stop includes a housing and a tumbler. The housing is adapted to be disposed in a recess in a rail or stile of the window/door. This housing includes a cavity with a bottom wall therein. The tumbler has at least one pivot for pivotally securing the tumbler to the housing for movement between an extended position, to prevent movement of the sliding member, and a retracted position, to allow movement of the sliding member. The tumbler is formed with a protruding spring member for selectively biasing the tumbler. The housing has one or more flexible members extending from each of its end walls to secure the housing within the opening in the sash member.

A closure device having a lock element that can be locked on a mating piece, preferably for closing a sealing flap of an opening, in particular an inspection flap, preferably in a drywall construction, in particular for a wall or a ceiling is provided.

A closure device is distinguished by the fact that the lock element is arranged in such a way that, preferably under the action of a spring, in a first position with respect to the mating piece it is or can be moved into a locking position and, in a second position, it reaches a position and/or a state without any blocking action.

The present invention relates to the field of locks and relates to a latchbolt mechanisms, comprising a rotatable latchbolt (16) and an elastic element (17), wherein the rotatable latchbolt (16) is fixedly mounted on a rotatable pin shaft, round which the rotatable latchbolt rotates. Therefore, a rotational unlocking and locking is enabled and is suitable not only for hinged doors, but also for sliding doors. By a rotary movement, actions of door opening and closing are avoided in a usual case.

An apparatus for a dump truck includes a catch affixable to one of the tailgate and the open-box bed of the dump truck, a latch affixable to the other of the tailgate and the open-box bed of the dump truck, a face cam affixable to the chassis or the open-box bed of the dump truck, a follower fixed to the latch, and a return spring affixable to the other of the tailgate and the open-box bed, and coupled to the follower. The apparatus is useful for providing a secondary locking device by engaging a tailgate or door assembly on a dump truck.

A latch and lock assembly includes a lever pivotable between a latched and unlatched position. A first actuator selectively moves a locking tab between a locked and unlocked position. In the locked position, the locking tab blocks pivotable movement of the lever from the latched position to the unlatched position. In the unlocked position, the locking tab allows pivotable movement of the lever from the latched position to the unlatched position. A second actuator selectively rotates a door opening tab between a first and second position when the locking tab is in the unlocked position is included. When the door opening tab is in the first position the lever is in a latched position, and when the door opening tab is rotated from the first position to the second position, the door opening tab abuts the lever and urges the lever from the latched position to the unlatched position.

A powered latch system for a door of a vehicle including a latch assembly, actuatable inside and outside handles, a powered actuator and a door controller that causes the powered actuator to unlatch the latch assembly upon actuation of the inside and outside door handles. The latch assembly may be mechanically unlatched by a user within a vehicle interior even if the powered actuator does not actuate due to a loss of electrical power or other failure. The controller can be programmed to unlatch the latch assembly according to various criteria as required to meet the specific requirements of different markets.

A sliding door includes a panel configured to slide along a path; a holding member including an abutting portion and defining a channel configured for receiving therein at least a segment of the panel; and a stop member being displaceable between an engaged state in which a first end of the stop member engages the abutting portion and a second end of the stop member engages the segment thereby precluding sliding of the panel in a direction away from the holding member and a disengaged state in which the stop member allows sliding of the panel.

The present application provides a lock (100) for a door. The lock comprises a housing (102), a lock mechanism (108), and a bolt (104). An end portion (112) of the bolt comprises a trigger (106). The lock mechanism is operable to move the bolt between a locked position in which the end portion extends through an opening in the housing and projects from the housing, and an unlocked position in which the end portion is within the housing. The lock further comprises a retraction mechanism (110), wherein actuation of trigger causes the retraction mechanism to automatically move the bolt from the locked position into the unlocked position.
