An emergency escape apparatus includes a support frame that is configured to be installed on a door or a wall and that defines an exit opening, an escape door that is located at an inner side of the exit opening and configured to open and close the exit opening and that defines an accommodation space, a driving unit located in the accommodation space and configured to rotate relative to the escape door, and an unlocking device that is located in the accommodation space, that is configured to be pushed by the driving unit, and that is configured to release coupling between the escape door and the support frame based on rotation of the driving unit. The driving unit is configured to be controlled by a control unit based on a sensor detecting an event.

An assembly can include a chassis that includes a chamber and an opening; a cover movable for access to the chamber via the opening; a cover latch; and a cover latch release that includes a push panel operatively coupled via a linkage to a pull panel that includes a finger grip surface, where the linkage rotates the pull panel responsive to rotation of the push panel to expose the finger grip surface, and where further rotation of the pull panel releases the cover latch.

The disclosed apparatus, systems and methods relate to a quick release grill guard further comprising at least one latching system configured for the quick release and pivot of the grill guard away from the vehicle grill face. The quick release grill guard may comprises a vehicle coupling portion, a clasped member an elongate bar and a clasping member. The clasping member may be constructed and arranged to be releasably engaged with the clasped member. Further, actuation of the elongate bar may cause the clasping member and clasped member to disengage.

A door that is adapted to separating two environments with different pressures and to an aircraft with such a door. The door may include a door leaf, a door frame having a door stop and a roller, and an actuating system having a latch element and an inward-moving drive system. The inward-moving drive system may include a puller shaft and a puller that is non-rotatably attached to the puller shaft. The puller may include a guide rail that moves along the roller during a rotation of the puller such that the puller moves the door leaf in direction of the first environment thereby disengaging the latch element from the door stop.

A locking assembly includes a first locking member, a rotating shaft for driving the first locking member to move, and a shell member. The first locking member is movably coupled to the shell member. An elastic element is coupled between the first locking member and the shell member. A first protruding portion is provided on an outer peripheral side of the rotating shaft. One end of the first locking member is provided with a first abutting portion. The first protruding portion abuts against the first abutting portion. The elastic element is used to maintain mutual contact between the first protruding portion and the first abutting portion. The first protruding portion rotates along with the rotating shaft to drive the first locking member to extend from or retract into the shell member.

The disclosed apparatus, systems and methods relate to a quick release grill guard further comprising at least one latching system configured for the quick release and pivot of the grill guard away from the vehicle grill face. In certain embodiments, the quick release grill guard further comprises a grill guard coupling portion, a vehicle coupling portion, a latching portion a hinge, a quick release bar; and a clasping member. In certain embodiments, the grill guard coupling portion is capable of being freely pivoted relative to the hinge by actuation of the clasping member by way of the quick release bar. In exemplary embodiments, the quick release bar is in operable communication with multiple latching systems so as to release the grill guard in a plurality of locations simultaneously.
