Abstract:
The guiding device, which serves for guiding a sliding element, such as a sliding door provided with a door leaf, with which a room opening of a building part can be closed at least approximately tightly, comprises a running rail having a longitudinal axis and at least one carriage that is guided along the running rail and that comprises a carriage body that is connected to a coupling device that is coupled or can be coupled with the sliding element.
Abstract:
The present invention relates to a rail and a door roller of a window and door system and a window operation apparatus for windows and doors using the same. The rail and the door roller of a window and door system and the window operation apparatus for windows and doors using the same according to the present invention include: one or more upper linear rail units 1 which are installed on an upper end of a window casing, are opened downward so as to rectilinearly guide a door roller 3 that is installed on an upper end of a window frame and has a vertical shaft 3a or a diagonal shaft 3b, have guides 4 that are vertically or diagonally formed at both sides thereof, and are rectilinearly formed to have a predetermined length; and one or more upper meandering rail units 2 which diagonally or curvedly guide an upper door roller 3, which rectilinearly moves on the upper linear rail unit 1, so as to operate the window frame in a horizontal direction, are installed to be connected to one side end of the upper linear rail unit 1 so as to be connected to the guides 4 of the upper linear rail unit 1 with the same cross section, and have guides 4 that are diagonally or curvedly extended.

The guiding device, which serves for guiding a sliding element, such as a sliding door provided with a door leaf, with which a room opening of a building part can be closed at least approximately tightly, comprises a running rail having a longitudinal axis and at least one carriage that is guided along the running rail and that comprises a carriage body that is connected to a coupling device that is coupled or can be coupled with the sliding element.
Abstract:
A flexible door assembly includes an upper guide track comprising an elongate bar including at least two generally planar support surfaces. The upper guide track is mounted in the elevator cab, or outside the cab in the hoistway, above the door opening, defining a non-linear pathway. A plurality of door sections each having a door panel, and a carriage assembly including a carriage frame and at least two wheels each supported by, and in rolling contact with, one of the at least two support surfaces on the guide track, a hinge pin supported by the carriage, a door panel pivotally connected to the hinge pin, and wherein the carriage, the hinge pin, and the door panel pivot about the same vertical axis defined by the longitudinal axis of the hinge pin when a door assembly has moved through a bend in the upper guide track.
Abstract:
Hardware for converting a door panel into a sliding door includes a pair of two-wheel trolley assemblies for supporting a door panel, a one piece track for attachment above a door opening, and a guide assembly for the bottom of the door panel for stabilizing the door when it is in the closed position. The track has running surfaces at 90.degree. to each other on which the wheels run. For use with doors for refrigerated rooms, one of the running surfaces has elevated portions for raising one wheel of each trolley. When on the elevated portions, the door panel is moved outwards from the door opening, thereby minimizing damage by the sliding panel to the door seals.
