A vehicle door structure includes two doors, a weatherstrip, a moving device and a control device. The two doors are disposed adjacently at a vehicle side portion with no pillar therebetween. The weatherstrip is provided at one of the doors and is disposed to change a distance between the weatherstrip and the other door. The moving device moves the weatherstrip in a direction of putting the weatherstrip into contact with and a direction of separating the weatherstrip from the other door. When it is determined that the two doors are closed and neither is opening or closing, the control device controls movement of the moving device to put the weatherstrip into contact with the other door. When a single door is closed and the counterpart door is opening or closing, the control device controls movement of the moving device in the direction of separating the weatherstrip from the other door.

A liftable closure element movable between a lowered and a raised configuration, is associated with a portal structure having a compartment for storing the closure element, delimited by a front wall, a space being provided which communicates with the compartment and with the outer environment between the wall and the closure element. An air seal device for the liftable closure includes first and second sealing members adapted to reach a facing position in which they adhere by magnetic attraction to close the transverse space, one connected to the wall for supporting a ferromagnetic plate, the other consisting of a magnetic member fixed to the closure element. The first sealing member includes a base structure which can be fixed to said wall by first and second adjustable fasteners in a position exactly corresponding to the position of the sealing member fixed to the surface of the closure element.

The invention relates to a drop-down seal for a building part comprising a housing (1), a sealing strip (2, 3) that can be raised and lowered in said housing (1), and a spring-loaded lowering mechanism (8), which causes automatic lowering of the sealing strip (2, 3) when the building part is closed. The lowering mechanism (8) is connected to a slide (4, 6), which protrudes beyond the housing (1) at one end and which activates the lowering mechanism (8) when the building part is closed. The slide (4, 5) applies a tension to the lowering mechanism (8). The drop-down seal according to the invention enables a one-sided triggering in tension, wherein the seal has a space-saving design.

A steam sterilizer having a door movable relative to an opening between a first open position and a second closed position. A plurality of spaced-apart roller assemblies are aligned along edges of the door to align the door relative to the opening as the door moves between the open and closed position. Each of the roller assemblies are comprised of a cylindrical roller having an outer annual recess extending along the periphery thereof. The recess is dimensioned to receive a lateral edge of the door. The roller is mounted on a shaft and is movable against a biasing force axially along the axis of the shaft.

A barricade used to obstruct the gap between a garage door, weather stripping, a threshold surface and a door frame. The barricade successfully prevents pests from breaching the barricade. The barricade uses a spring assist with low displacement force in order to conform to the changing downward or upward angle when a garage door is being operated. It also includes smooth ceramic or rubber that is magnetized to prevent chaffing to the garage door surface. This barrier stays in-place or rotates relative to the garage door face when encountering foreign objects in the path of the moving garage door. Alternatively, the barriers may be constructed of overlapping and/or abutting material configured to obstruct gaps at door frames and/or at threshold surfaces where a weather stripping and/or weather-stripping bulb provide inadequate obstruction.

A door assembly for an electromagnetic shielded enclosure includes a metal door frame for defining a passageway into the enclosure and a door for selectively enclosing the passageway. The door includes a door leaf pivotally coupled to the frame. A set of radio frequency (RF) seals is connected to the exposed peripheral edge of a conductive plate in the door leaf. Each RF seal includes a resilient movable finger which overlies a U-shaped bracket mounted along the outer edge of the door leaf. A plurality of air cylinders is mounted within each bracket and is designed to urge the resilient finger of each RF seal into contact with the door frame.
