ACTIVE SEALING/LOCKING USING THE CONSTRICTION PRINCIPLE

Abstract

A sealing system for an opening in a wall surface includes a wall surface with an opening, having a circumferential inner surface, a leaf adapted to the geometry of the opening to be inserted into the opening and closed, wherein a circumferential outer surface of the leaf is arranged facing the inner surface of the opening in the closed state.

A sealing device is formed by a first sealing element arranged in the inner surface and moved towards and away from the outer surface.

The system includes, a drive element that drives the first sealing element in the opening plane towards the outer surface of the leaf into a sealing position and produces a force in the direction of the outer surface such that when the opening is in the closed state, the first sealing element comes into sealing contact with the outer surface when acted upon by force.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The disclosure is explained in more detail based on the following figures. The figures should only be understood as examples and are not intended to limit the disclosure to the exemplary embodiments shown. In particular, it should be pointed out once again that the explanation is only given by way of example using a door leaf or a door; all features can also be applied to two opening window leaves, for example. The figures are also only schematic diagrams, with not all aspects being to scale.

[0027] In the figures:

[0028] FIG. 1: shows a simplified schematic diagram of an open door leaf, which is not sealed or locked,

[0029] FIG. 2: shows a simplified schematic diagram of the closed door leaf, which is not sealed or locked,

[0030] FIG. 3: shows a sectional view of the region A, A from FIG. 2,

[0031] FIG. 4: shows a simplified schematic diagram of the closed door leaf, which is sealed or locked, and

[0032] FIG. 5: shows a sectional view of the region B, B from FIG. 4.

DETAILED DESCRIPTION OF THE DRAWINGS

[0033] The figures show a sealing system 20 according to the disclosure by way of example. They show a leaf 22, in this case a door leaf arranged in an opening 24 of a wall surface 25. A drive element 26, designed as a tensioning device, is arranged above the opening or door opening 24.

[0034] The drive element 26 is connected to a tensioning element 28, designed as a steel cable or steel strip. The tensioning element 28 surrounds the door opening 24 in the manner of a strap. The drive element 26 is designed in such a way that it can contract the tensioning element 28, which reduces the size of the strap formed and constricts the door leaf 22, shown by the arrows in FIGS. 4 and 5.

[0035] The door leaf 22 is constricted by virtue of the fact that the tensioning element 28 moves a first moveable sealing element 30 towards an outer surface of the closed door leaf 22. For this purpose, in a particularly advantageous embodiment, the tensioning element 28 is arranged within the first sealing element 30, which in turn is moveably mounted in a guide profile 32 (cf. in particular FIGS. 3 and 5). In the exemplary embodiment shown, the first sealing element 30 has two components, one sealing means 34 that can be moved towards and away from the outer surface of the closed door leaf 22 and one retaining means 36 connected thereto and immovably fixed in the guide profile 32. The retaining means 36 is held in a groove 38 of the guide profile 32, the tensioning element 28 extends through the sealing means 34 parallel to an inner surface of the opening 24.

[0036] A restoring element 40 designed as a spring element is also shown. This is arranged within the first sealing element 30 between the sealing means 34 and the retaining means 36 and produces a force in the direction of the inner surface of the opening 24, i.e. in the opposite direction of the constricting force of the tensioning element 28. When the tensioning element 28 is released, the restoring element 40 causes the first sealing element 30 or the sealing means 34 to move away from the leaf 22, releasing it.

[0037] In principle, the restoring element 40 must be arranged between an inner surface running around the opening 24 and the moveable first sealing element 30 or the moveable sealing means 34. The proposed design of the first sealing element 30 with a retaining means 34 is not compulsory. The same applies to the tensioning element 28, which can also be designed differently than what has been described, adapted to the first sealing element 30. For example, it is conceivable that the entire first sealing element 30 is moveable and the tensioning element 28 extends between the first sealing element 30 and the inner surface of the opening 24.

[0038] FIGS. 1, 2 and 4 show the arrangement of the drive element 26 above the opening 24. Alternatively, the drive element 26 can also be provided at a different point, but preferably outside the opening 24. The drive element 26 can be implemented by various means, for example by a spindle on which the tensioning element 28 is wound and unwound.

[0039] FIGS. 3 and 5 show a second sealing element 42 arranged on an outer surface of the leaf 22. In the exemplary embodiment shown, the two sealing elements 30,42 that come into contact with each other are designed in such a way that the leaf 22 is held in a form-fitting manner in the constricted, closed state in the opening direction, i.e. transversely to the main extension plane of the opening 24. This is achieved by the fact that the second sealing element 42 has a receiving groove 44 for a projection 46 of the first sealing element 30. During the constriction process, the projection 46 moves into the receiving groove 44, thus coming into contact with the receiving groove 44 on three sides, with a front surface and two sides. This ensures an exceptionally good sealing effect.

[0040] In one particularly advantageous embodiment, the sealing system 20 is designed in such a way that it not only seals the leaf 22, but also locks it in the opening 24.

[0041] This can be achieved by virtue of the fact that the two sealing elements 30,42 are suitably resistant. This is the case here, whereby the two sealing elements 30, 42 not only seal the door system, but also at the same time lock the leaf 22 in the opening 24.

[0042] The disclosure is not limited to the exemplary embodiments shown, but also includes further variants of the disclosure.
