A door for an aircraft configured to be selectively closed on a frame, the door comprising a safety system for an anchoring element, the safety system comprising a source of light radiations and a receptor of said radiations, the source being integral with the door and the receptor being integral with the anchoring element, said receptor being optically connected to signalling means, signalling the positioning of the anchoring element in the second operating condition when the receptor receives the light radiation from the source.

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.

A transmission system allowing a window to be opened in three directions includes a door hinge assembly, a guide wheel assembly, a lock assembly, a handle, a first transmission lever, a second transmission lever, an angle converter, a first gear tooth combination, a second gear tooth combination a and a second gear tooth combination b. The angle converter is connected at a position of the first transmission lever and a position of the second transmission lever located at corners of a window sash. The first gear tooth combination is arranged in the handle. The second gear tooth combination a and the second gear tooth combination b are connected to the top and the bottom of the window sash respectively. The lock assemblies are symmetrically provided at two sides of the second gear tooth combination a and the second gear tooth combination b.

The current disclosure relates to a tank trailer for transporting meat packaging by-products. The tank trailer has a cylindrical body having a sloped rear end. An opening is formed in the sloped rear end, and a gate selectively blocks the opening. A locking mechanism is provided to securely lock the gate to the cylindrical body, thereby sealing the cylindrical body. The sloped rear end forms a chute through which meat by-products can be poured. The chute extends for a distance rearwardly of the trailer's rear wheel assembly.

A door of a substrate container includes a latching mechanism for operating at least two latch members. The substrate container can be a front opening substrate container or a bottom opening substrate container. The latching mechanism can include a rotatable cam having a first rotational profile out of phase with a second rotational profile such that when the cam is rotated to operate the latch mechanism from the disengaged position to the engaged position, a first latch member engages a first corresponding slot in a door frame prior to a second latch member engaging a second corresponding opening provided in the door frame such that the latch members are operated in a staggered manner. This staggered latching configuration allows for the application of a load provided by the system to be used in the most efficient manner per latch arm or per set of latch arms.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a multipoint lock. The multipoint lock may include a horizontally translating lock bolt and at least one vertical translating lock bolt. In addition, the multipoint lock includes a linkage coupled to and configured to translate the horizontally translating lock bolt and the at least one vertical translating lock bolt. Further, the multipoint lock includes a gear mechanism configured to actuate the linkage and to effect translation of the horizontally translating lock bolt and the at least one vertical translating lock bolt.

A latching mechanism for securing a door mounted to a door frame comprises a striker pin mounted to the door frame; a pawl comprising a first arm for holding the striker pin captive when the pawl is in a latching position; and an actuator moveable relative to the door for opening or closing the door. The actuator is configured to pivot the pawl from the latching position to an open position according to movement of the actuator. The actuator comprises a biasing mechanism for urging the pawl to remain in the latching position until a resistance of the biasing mechanism is overcome by operation of the actuator.

A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.
