A linear reciprocating-motion apparatus includes at least one movable member (10, 30) supported by a housing (90) and being capable of undergoing linear reciprocating motion in a range that includes a first position, a second position, and a third position; a stopper (50) supported by the housing to be displaceable between a blocking position that blocks the at least one movable member and a nonblocking position that does not block the at least one movable member, and is displaced to the nonblocking position in response to a specific operation; an intermittent mechanism (100, 200) that interacts with movement of the at least one movable member and assumes a specific state once every two times that the at least one movable member moves to the third position; and a switch (SW1) that, in response to the specific state, is switched from a disconnected state or a connected state to the other thereof.

A latch assembly is provided where the latch is moveable to open and close a door by operation of a dead lock assembly that blocks or unblocks movement of a bolt. In a blocked state, a blocking cartridge of the dead lock assembly is prevented from inward movement, blocking inward movement of the bolt. Turning a door knob or door handle causes a spindle extending through the dead lock assembly to move locking bars of the dead locking assembly, the locking bars moving further apart to permit the blocking cartridge to slide there between and move inwardly into the latch housing. The bolt can now move inward by force of the door jamb upon the bolt in order to clear the door jamb when opening and closing the door.

A door lock device for a household appliance, including a support body which can be attached to a structural element of the household appliance, and a movable deadlock designed to cooperate with a receiving seat of a door of the household appliance; the movable deadlock having: a locking tooth connected to the support body for translation and rotation relative to the latter along a predetermined trajectory to cooperate by a first end with the receiving compartment; a rod carried in axially sliding manner by the support body and connected by means of an articulated device to a second end of the locking tooth; first elastic compression means operatively associated with the rod and configured to push the rod toward the locking tooth; and a control device comprising a movable element carried by the support body and operatively associated with the locking tooth, cooperating during use with the door to insert the locking tooth in the receiving seat.

An aircraft panel system including a first panel, having a hinged coupling configured to couple the first panel to an aircraft structure, a second panel disposed adjacent to the first panel such that the first panel and the second panel together form cabin surface of an aircraft, and a latch mechanism configured to releasably couple the second panel to the aircraft structure, where the first panel is configured to pivot about the hinged coupling from a latched position to an actuation position to actuate the latch mechanism and cause a release of the second panel from the latch mechanism.

The disclosure relates to a push-and-pull latch device including a housing, a latching component, a first elastic component, an inner-sleeve assembly, an inner-shaft component, a second elastic component and a third elastic component. The first elastic component abuts the latching component. The latching component engages an object through the housing. The inner-sleeve assembly is accommodated within the housing. The inner-shaft component is partially accommodated within the inner-sleeve assembly. The second elastic component is abutted between the inner-shaft component and the inner-sleeve assembly. The third elastic component includes a fixed portion connected to the inner-shaft component and an engaging end engaged with a guide groove of the inner-sleeve assembly. By driving the inner-shaft component to move the engaging end relative to the guide groove or move the inner-sleeve assembly relative to the housing, the relative positions between the components can be switched to provide the functions of opening and closing.

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.
