An assembly for assisting in lifting a tailgate includes an elongated housing extending along a predetermined length, a spring anchored at one end at a first end of the housing, and a connector having a first end affixed to the opposite end of the spring and extending through the housing. In one embodiment, at least three rollers are provided for engaging the connector. The rollers may be arranged in a variety of configurations to maintain the connector and spring in a generally centered location within the housing. In another embodiment, at least two vertically aligned guides are provided. A vehicle for integrating the foregoing assemblies is also provided.

A door roller includes a carriage member comprising a plurality of bores, and a plurality of roller assemblies connected to the carriage member, each roller assembly of the plurality of roller assemblies including a pivot bearing rotatably disposed within a bore of the plurality of bores and a pair of rollers coupled to the pivot bearing. Each wheel assembly is configured to pivot relative to the carriage member.

A link mechanism for a vehicle door is provided. The link mechanism includes a body having a first end portion facing a vehicle body and a second end portion facing a vehicle door and a first mounting member that is mounted on the vehicle body, and rotatably connected to the first end portion of the body through a first shaft. A second mounting member is mounted on the vehicle door, and is rotatably connected to the second end portion of the body through a second shaft. A rotation restricting unit selectively restricts a rotation of the second mounting member.

A platform screen door system having a fixed panel and a door panel, wherein the system is provided with a track (11) having a convex surface adapted to support a roller (14), which roller is rotatably mounted on the moving panel and has a concave surface and has two points of contact (17) on the track.

A roller assembly for a sliding vehicle door includes a bracket structure having a first and second inner horizontal guide roller arranged to interact with an inner vertical surface of the track member. The bracket structure further includes at least a first and second vertical guide roller arranged to interact with a first inner surface of the track member, a resiliently arranged rotatable member arranged to interact with a second inner surface of the track member and at least one outer horizontal guide roller arranged to interact with an outer vertical surface of the track member.

A track door system for an aircraft includes a door having a first side and a second side opposite the first side. A first roller track and a second roller track are aligned adjacent one another on the first side of the door. A third roller track and a fourth roller track are aligned adjacent one another on the second side of the door. A first motion driver is configured to move the door along the first roller track and the second roller track. A second motion driver is configured to move the door along the third roller track and the fourth roller track. A drive unit is operatively coupled to the first motion driver and the second motion driver to provide electromechanical power for cooperatively moving the door forward to an open position or aft to a closed position.

A sliding door roller assembly includes a roller housing being at least partially disposed within an outer housing moveable relative to the roller housing and at least one roller wheel in a direction perpendicular to a rotational axis of the at least one roller wheel. At least one resilient member is positioned at an end of the outer housing, and includes a fixed termination section coupled to an end member of the outer housing, a compliant section extending from the fixed termination section, a curved engagement section, and a resilient section between the compliant section and the curved engagement section and pivotable about the compliant section. The at least one resilient member is flexible from a first position to a second position when the curved engagement section mates with an inner surface of a slot defining a bottom edge of a panel secured to the outer housing to provide a holding force between the resilient member and the inner surface of the slot.

Proposed is a door hinge. More particularly, there is provided a door hinge which is conveniently assembled, has a minimized shape, and above all, enables a closing force to be applied to a door so that when the door is opened, high-temperature heat is inhibited from being released from inside an apparatus on which the door hinge is installed.

A hybrid drive-thru door system that includes a door panel assembly movable between a plurality of operating modes. The door panel assembly includes a sliding door panel operable for movement between a closed position to at least partially cover a doorway opening and an opened position to at least partially expose the doorway opening. The sliding door panel has an upper sliding door panel member releasably attached to a lower sliding door panel member. The upper sliding door panel member is independently movable relative to the lower sliding door panel member in a window operating mode of the door panel assembly.

A sealing assembly for pressing a garage door horizontally into weather stripping or a door jamb; the sealing assembly having at least one cam-stop assembly, the cam-stop assembly further having at least one cam assembly, at least one linking assembly coupling the cam-stop assembly to the cam assembly, and at least one stop brace. The garage door is sealed when a combination of cam-stop assemblies having cam assemblies—further comprising at least two triangular hinge plates and corners—couple with stop braces and rotate counter-clockwise by exertion of torque to move the garage door forward and downward to form a snug seal with the side of the door jamb and also the bottom floor.
