A door lock mechanism for actuation of the locking slide of a disconnector on a control box, includes a setting mechanism, that may be disposed between a locking position and a released position and that is pre-loaded toward the locking position, wherein the setting mechanism comprises a shaft that is pivoted around a rotation axis, wherein the shaft comprises at a first end a first lever that may be coupled with the locking slide of a disconnector, and wherein the shaft comprises at a second end opposing the first end a second lever having an actuating bolt so that upon pivoting the second lever the first lever conducts a respective pivoting; and a locking nose to be mounted at the inside of a control box door wherein the locking nose comprises starting from its tip an approach slope turning into a catch that turns into a contour slope so that upon closing the control box door the actuating bolt is guided along the contour slope in direction of the release position and against the pre-load.

A latch is provided including a claw configured to rotate between an open position and a closed position. A pawl is rotatable in and out of engagement with the claw. The latch includes a first release mechanism, a second release mechanism, and a third release mechanism. The first release mechanism applies a rotational force to a first portion of the pawl to rotate the pawl out of engagement with the claw. The second release mechanism applies a rotational force to a second portion of the pawl to rotate the pawl out of engagement with the claw. The third release mechanism applies a rotational force to a first portion of the pawl to rotate the pawl out of engagement with the claw.

A pressing type latch device includes a seat, a pivotal seat mounted in the seat, and a handle having a grasping portion pivotably connected to two eccentric locations of the pivotal seat, such that a greater operational height can be formed when the handle is lifted. When the latch device is in one of a plurality of retainable open positions or a retainable closed position, the grasping portion of the handle can be moved to a position to lift the pivotal seat, such that the grasping portion of the handle lies flush with the pivotal seat. On the other hand, when the grasping portion of the handle is lifted to move the pivotal seat downward, the handle and the pivotal seat can rotate freely. Since the latch device includes a closed position and a plurality of open positions, the latch device can be installed and used more easily.

A latch is disclosed herein. The latch having: a fork bolt movably mounted to the latch for movement between an open position and a closed position; a detent lever movably mounted to the latch for movement between a latched position and a released position, wherein the detent lever prevents the fork bolt from moving from the closed position to the open position when the detent lever is in the latched position; a hold open lever configured to engage and retain the detent lever when it moves from the latched position to the released position; and wherein the fork bolt is configured to disengage the hold open lever from the detent lever when the fork bolt travels away from the closed position.

A vehicle door latch assembly is disclosed herein, having: a fork bolt movably secured to the latch assembly; a detent lever movably secured to the latch assembly, the detent lever being capable of movement between an engaged position and a disengaged position, the detent lever retains the fork bolt in a latched position when the detent lever is in the engaged position and an engagement surface of the detent lever contacts an engagement surface of the fork bolt; an inertia block out assembly for preventing the detent lever from moving into the disengaged position when the inertia block out assembly is in a blocking position; and a manual override mechanism for the inertia block out assembly, wherein the manual override mechanism requires at least three independent actions to be performed to move the inertia block out assembly from the blocking position to an unblocking position.

A lever-lock release system is configured to releasably couple two objects together, for example a parachute and a payload. The lever-lock release system may comprise a first lever and a second lever, each rotatably coupled to a rigid base. When activated, the levers cascadingly rotate to release a first object and a second object. With these systems and related methods, various failure modes may be eliminated, such as undesired premature deployment of recovery parachutes during aerial delivery.

A latch and a method for preventing a latch from failing to open while a connected handle is lifted are provided. The latch includes a primary pawl pivotally mounted to the latch. An end piece having a protrusion extending from it is fixed to the primary pawl. An inner lever is rotatably coupled to the end piece. The inner lever includes a tail adjacent the protrusion of the end piece. The inner lever is movable between a first position and a second position. A secondary pawl is pivotally mounted to the latch and is movable between a first position and a second position. A blocking lever is also coupled to the latch and movable between a first position and a second position. When the inner lever is in a second position, the tail abuts the protrusion and the blocking lever limits movement of the inner lever and the primary pawl.

The invention is directed to lock for a vehicle door arrangement, wherein a catch and a pawl are provided. The catch can be brought into an opening position and into a closed position, wherein the catch, which is in the closed position, is or may be brought into holding engagement with a lock striker. The pawl may be brought into an engagement position. A pawl actuation lever is provided for deflecting the pawl into the release position. A switchable coupling arrangement comprises a first coupling lever on the side of the pawl actuation lever, a second coupling lever on the side of the pawl and a moveable coupling element that may be moved into a closing position for a coupling engagement with the two coupling levers and into an opening position for decoupling the two coupling levers. The coupling element is arranged on one of the two coupling levers.

A vehicle latch (1) comprising a ratchet (15); a primary pawl (25) movable between a ratchet checking position and a ratchet release position; an auxiliary ratchet (26) movable between an enabling position and a disabling position; a secondary pawl (27) movable between an auxiliary ratchet holding position, in which the secondary pawl (27) is positioned to hold the auxiliary ratchet (26) in its enabling position, and an auxiliary ratchet release position; electrically-operated actuator means (6) for moving the secondary pawl (27) to the auxiliary ratchet release position and the auxiliary ratchet (26) to the enabling position; a back-up mechanism (7) for moving the secondary pawl (27) to the auxiliary ratchet release position or the auxiliary ratchet (26) to the enabling position; and an inhibiting lever (81) for selectively preventing interaction of the back-up mechanism (7) with the auxiliary ratchet (26).

A high visibility hook latch may include a hook arm having a proximal end and a distal end; a handle pivotably attached to the proximal end of the hook arm; and a connector having a first connector end pivotably attached to the distal end of the hook arm via a link and a second connector end pivotably attached to the handle proximate to the hook arm.
