A door management system on an aircraft includes a fuselage extending along a longitudinal axis in a fore-aft direction parallel to forward flight, an opening in a sidewall of the fuselage, a door mounted on the sidewall to slide in the fore-aft direction between a closed position covering the opening and an open position revealing the opening, a cable attached to the fuselage and the door and a speed governor operatively coupled to the cable to limit a velocity of the door as it moves between the open position and the closed position.

A refrigerator includes a refrigerator body having an interior storage space. A door is coupled to the refrigerator body to open and close the interior storage space. A door handle is coupled to the door in a pivotally rotatable manner and an opening actuator is coupled to the door handle where the opening actuator applies a force to the refrigerator body to open the interior storage space. The opening actuator includes a front bezel, a handle pivot plate coupled to the door handle, a casing enclosing an actuator mechanism, and one or more pushers that extend and retract against a front wrapper edge of the refrigerator body. An intermediate attachment couples the handle pivot plate to the casing and a back bezel.

A door operator comprises a rotary shaft, a chain disk for rotating the rotary shaft, and a locking mechanism for locking the rotary shaft. The locking mechanism comprises a bidirectional rotary block, a plurality of push pins and anti-rotation posts. When the chain disk rotates, the push pins urge the bidirectional rotary block to rotate the rotary shaft, and when the rotary shaft rotates, the of anti-rotation posts lock the bidirectional rotary block, and preclude the rotary shaft from rotating.

A vehicle enclosure system may include a top rail and a bottom rail coupled to a side of a vehicle. The vehicle enclosure system may also include a housing coupled to the side of the vehicle. The housing may include a covering coupled to at least one handle. The at least one handle may be configured to facilitate a movement of the covering by a user. The housing may include a roller configured to facilitate the movement and storage of the covering. The vehicle enclosure system may include a rear cover assembly coupled to the housing and the covering. The covering may enclose an interior of the vehicle and extend the rear cover assembly simultaneously when the covering is moved to a deployed position. The covering may expose the interior of the vehicle and store the rear cover assembly simultaneously when the covering is moved to a storage position.

A window, with a hybrid sash counterbalance and assist mechanism, includes a frame having upper and lower sashes slidable within the frame. A sash coupling element extends between the upper and lower sashes. The hybrid sash counterbalance and assist mechanism is coupled with the sash coupling element. The window with the hybrid sash counterbalance and assist mechanism is operable in a sash counterbalance mode and in an independent sash movement mode. In the sash counterbalance mode, movement of the upper or lower sash causes converse movement of the lower or upper sash through the sash coupling element. In the independent sash movement mode, one of the upper and lower sashes is held static while the other of the lower or upper sashes is moved.
