Embodiment Construction

[0037] Generally, the present invention relates to a door assembly for closing a door opening in a wall. The door assembly includes a first flexible door and a second door, one behind the other, so that the other door can be used to close the door opening when the other door is open.

[0038] The use of such a door assembly is of particular interest when the second door is constituted by a rigid door which moves relatively slowly between the closed position and the open position. If people or vehicles pass through the door opening with a relatively high frequency, when it is necessary to wait for the opening of the rigid door, the opening and closing of the rigid door results in wasting a lot of time. Having a flexible door that can be closed or opened at high speed overcomes this disadvantage. Thus, the rigid door is kept in the open position when waiting for traffic at a relatively high frequency, and in the closed position at night when there is no traffic.

Abstract

The invention relates to a door assembly for closing a door opening (3) in a wall (4), comprising a first flexible door (1) and a second door (2) having at least one rigid lower edge (17) , each of these doors (1, 2) can perform an upward movement and a downward movement between an open position and a closed position, respectively, and the second door (2) is set so that when the second door moves to the open position During ascent, a gap (31) is created between the wall (4) and the rigid lower edge (17) of the second door (2). The flexible door (1) is at least partly located between the second door (2) and the wall (4), and when the second door (2) is in the open position, the flexible door can pass through the gap (31) in its open position and Move between closed positions.

Description

technical field [0001] The present invention relates to a door assembly for closing a door opening in a wall comprising a first flexible door and a second door having a rigid lower edge, each of the doors being movable in an open position and a closed position respectively Perform an ascending movement and a descending movement between, and the second door is set so that when the second door rises toward the open position, its lower edge leaves the wall, creating a gap between the wall and the lower edge of the second door. [0002] Said second door is formed, for example, by a sectional door consisting of a series of rigid sections hinged relative to each other. When the second door is in its closed position, the sections and lower edge of the door rest against the wall, while in the open position a gap is created between the portion of the wall above the door opening and the lower wall of the door. Background technique [0003] Currently known door assemblies have a relat...
