Provided are door systems having a plurality of door panels and a frame, the door panels being movable between an extended position closing an opening in a building structure, and a folded retracted position. When in the extended position, the door panels interlock with each other forming a barrier to wind, dirt, dust and insects. The frame is movably attached to the building structure and when the door panels are in the extended position, the frame moves and engages the door panels with a sealing member to provide an airtight seal of the opening in the building structure.

A console box includes a box body that includes an opening portion, a lid supported by a hinge shaft on the box body, and an opening/closing mechanism that tilts the lid. The opening/closing mechanism includes a main rack that includes an engaging portion and a sub-rack that includes an engaged portion. When the lid is tilted between an opened position and a closed position, the engaged portion engages the engaging portion and restricts sliding of the sub-rack on the main rack. When the lid is further tilted from the closed position in a closing direction in which the lid closes the opening portion and when the lid is further tilted from the opened position in an opening direction in which the lid opens the opening portion, the engaged portion is disengaged from the engaging portion to cancel the restriction imposed on the sub-rack by the main rack.

In a preferred embodiment, a telescoping panel door for an aircraft compartment includes a first panel configured for hinged connection to a surface of a door frame, a second panel, and a linkage fixing a distance that the second panel can extend from the door frame, where the second panel is configured for connection to the door frame via the linkage. The door operates such that, in a closed position, the second panel is extended from an interior of the first panel, the first and second panels cooperate to completely cover an opening defined by the door frame, and the linkage is generally parallel to the plane defined by the door frame. In an open position, the second panel is retracted into the interior of the first panel by operation of the linkage and the first and second panels are nested to reduce a distanced spanned by the panels.

According to some embodiments, a railcar with a pair of sidewall assemblies and a hopper comprises a plurality of transverse discharge openings. The railcar comprises a sliding gate assembly coupled to the hopper to control the discharge flow of lading. The sliding gate assembly comprises a support frame coupled to the hopper proximate the transverse discharge openings. The support frame extends longitudinally along the sidewall assemblies. The sliding gate assembly further comprises a plurality of discharge gates slidably coupled to the support frame; and a gate actuator operable to slide the plurality of discharge gates between a closed position, where each discharge gate is disposed adjacent to each of the discharge openings to restrict the discharge flow of lading, and an open position, where each discharge gate is disposed between discharge openings to permit the discharge flow of lading.

An oven appliance includes a cabinet that defines a chamber. A pair of doors is rotatably mounted to provide selective access to the chamber of the cabinet. The pair of doors is connected with a linkage assembly such that the doors rotate open and closed simultaneously. The linkage assembly includes a spur gear that engages another gear of the linkage assembly. The spur gear can hinder unwanted rotation of the pair of doors or compress the pair of doors against a seal.

A mechanism for conjointly operating a plurality of gate assemblies mounted on a hopper car having an elongated car body with sides and ends, and a bottom defining a discharge area comprised of a plurality of discharge openings. Each gate assembly includes a slide door arranged in operable association with one of the discharge openings. The mechanism operates the slide door on all the gates conjointly relative to each other. Methods for controlling the gravitational discharge of material from a hopper car are also disclosed.
