Abstract:
1. A lifting door comprising a movable door leaf and building-mounted frames disposed on either side of a door opening, wherein mutually facing, lateral guides for the door leaf are arranged at the frames, the lateral guides comprising a vertical section and a lintel section, wherein the door leaf is formed of slats pivotally connected to each other and in the closed condition covers the door opening, wherein the door leaf is guided in the lateral guides such as to be accommodated in the lintel sections in the opened state of the lifting door and in the vertical sections of the guides in the closed condition of the lifting door, wherein the vertical sections of the guides are mounted on the frames so as to be displaceable, whereby in the closed condition of the lifting door-the door leaf may be displaced in a direction toward the outer side of the door, and wherein the lifting door further comprises a drive unit for operating the door leaf, frame sealing elements of a seal are furthermore arranged at the frames, wherein in the closed condition of the lifting door the door leaf presses against the seal, wherein a frame-side actuator initiates the displacement of the vertical sections of the guides by contacting a plurality of displacement mechanisms, the plurality of displacement mechanisms including a plurality of deflection rollers, and the vertical sections of the guides are mounted on the frames so as to be displaceable perpendicularly to the plane of the door leaf and fixed in the direction of vertical movement of the door leaf, wherein the actuator comprises an actuation rod and a plurality of actuation blocks having guide surfaces, wherein the plurality of deflection rollers rollingly engage the guide surfaces concurrently to transmit linear horizontal force at multiple locations of the vertical sections of the guides to displace the guides perpendicularly to the plane of the door leaf.
