Claim Text:
1. A lifting door comprising: a movable door leaf, the door leaf comprising a plurality of slats connected to one another so as to bend, the door leaf arranged to cover a door opening in a closed condition; a drive unit configured to move the door leaf; structure-mounted frames arranged on both sides of the door opening; a plurality of lateral guides arranged at the frames, each of the plurality of lateral guides comprising a vertical section and a lintel section; a sealing assembly with frame sealing elements arranged at the frames, wherein the frame sealing elements close a gap between the door leaf and a section of the frames facing the door opening when the lifting door is closed, wherein the door leaf is pressed against the sealing assembly when the lifting door is closed; a trigger device comprising an actuating rod and a plurality of actuating blocks having guide surfaces; a frame-side actuator comprising a plurality of deflection rollers in a vertical spaced apart relation; wherein the door leaf is guided in the lateral guides such that it is disposed in the lintel sections when the lifting door is open and in the vertical sections of the lateral guides when the lifting door is closed; wherein the lintel sections and the vertical sections of the lateral guides are displaceably mounted on the frames, so that the door leaf is displaceable in a direction to an outer side of the lifting door when the lifting door is in the closed condition; wherein the trigger device is configured to cause the guide surfaces to engage the plurality of deflection rollers concurrently to effect displacement of the vertical sections at the frames; wherein the lintel sections of the guides form a spiral configuration having spaced-apart lateral guide regions, wherein the door leaf, in an open condition of the lifting door, is disposed within the spaced-apart lateral guide regions; and wherein the guides can only be displaced in a linear horizontal direction, but not in a moving direction of the door leaf.
