The present invention is a lock system that can be used in the entire sector of white appliances and characterized by comprising a lock bolt (4) that fits into its seat through the stretching of the lock bolt housing (6) by means of the spring (3) located on the body (1) and a mechanism that allows the machine hatch to be closed by restoring the lock bolt housing (2) back to its former position even if the lock bolt housing (2) is in closed position.

A fastener operating structure includes a holding base and a fastening-connecting unit. The holding base is disposed at a first object. The fastening-connecting unit is movably disposed at the holding base. The fastening-connecting unit is fastened to a second object. Consequently, the holding base is disposed at the first object, and the fastening-connecting unit is coupled to or removed from the second object, so as to couple together and separate the first and second objects repeatedly and quickly.

A door assembly includes a frame having interconnected wires that define an opening for an animal to pass therethrough, and a door having interconnected wires and being coupled to the frame. A latch assembly has a handle structure and a pin. The handle structure is pivotable with respect to one of the door and the frame, and the pin is movable axially with respect to one of the door and the frame. A first wire of the plurality of wires of the frame forms a key hole assembly. The key hole assembly defines an aperture for receiving the pin when the door is in a latched position with respect to the frame. A tab assembly is formed by at least one wire of the door and is disposable behind at least one of the plurality of wires of the frame in the closed position.

An aircraft trolley retention device may include a retention latch with a shaft including a first component of an interlocking assembly and a sleeve including a second component of the interlocking assembly and configured to receive the shaft, and an interlocking assembly. The retention latch may be configured to actuate between a closed position and an open position. The interlocking assembly may be configured to guide the retention latch during the actuation between the closed position and the open position. The retention latch may be configured to retain an aircraft trolley within an aircraft trolley bay when the retention latch is in the closed position. A portion of the retention latch may be configured to be positioned in front of a striker plate corresponding to a handle of an aircraft trolley bay door of the aircraft trolley bay when the retention latch is in the open position.

A latch assembly is provided that includes a latch arm having a rotational axis and an engagement surface on a distal end of the latch arm a length from the rotational axis. The engagement surface is stowed in a stowed state of the latch arm. The latch arm is configured to receive a pushing force to depress the latch arm a predetermined distance along the rotational axis. The latch assembly also includes a turret assembly having a top end with the latch arm mounted thereon. The turret assembly is configured to, in response to the pushing force being applied to the latch arm, raise and rotate the latch arm about the rotational axis to thereby transition the latch arm from the stowed state to a deployed state in which the engagement surface is exposed.

A latch is configured to fix a panel relative to a frame. The latch includes a housing having a longitudinal axis and defining an aperture along the longitudinal axis; a cap mounted within the aperture of the housing for rotation about the longitudinal axis, the cap comprising a drive surface; and a cover coupled to the housing to pivot about a lateral axis, the cover pivotable to be in a closed position in which the cover covers the cap; wherein when the cap is in an unlatched position, the drive surface of the cap is aligned with an engagement surface of the cover and positioned to block the cover from pivoting to the closed position; and wherein when the cap is in a latched position, the drive surface is unaligned with the engagement surface and positioned to permit the cover to pivot to the closed position.
