DESCRIPTION OF PREFERRED EMBODIMENTS

[0022] Referring to the drawings, the view in FIG. 1 shows an embodiment of a particular a gas-tight sealing device generally designated 10, shown in a schematically simplified sectional view. The gas-tight sealing device 10 comprises a sealing device portion (a wall/barrier that is gas impermeable) 11, which gas-tightly encloses a coupling element 12 acting, for example, as a removal point (gas removal point) for combustible gas, especially a coupling element 12 in the form of or configured as a tube connection bushing, as well as a section of a line element 14 connected to the coupling element 12, i.e., for example, a section of a flexible tube. The gas-tight sealing device 10 adjoins for this the line element 14, extending all around in a gas-tight manner, at a first sealing point (sealing edge) 16, and the gas-tight sealing device 10 comprises for this, for example, a seal, which is in contact with the outer surface of the line element 14 in the area of the first sealing point 16 in a manner that is known, in principle, per se, and thus ensures a gas-tight closure. The gas-tight sealing device 10 likewise adjoins at a second sealing point (sealing edge) 18, extending in a gas-tight manner all around, either the coupling element 12 or, as is shown here, a wall 20, for example, a housing wall, a building wall or the like, namely, a wall 20, in or at which the coupling element 12 is mounted. Here as well, the gas-tight sealing device 10 comprises, for example, a seal, which is in contact with the surface of the wall 20 in the area of the second sealing point 18, in a manner known, in principle, per se. Instead of a seal in the area of the first and/or second sealing point 16, 18, the gas-tight sealing device 10 may also be gas-tightly connected to the line element 14 or to the coupling element 12 or to the wall 20 with the first and/or second sealing point 16, 18 comprising a bonded connection. Such bonded connection sealing points (bonded sealing edges) 16, 18 have the advantage that the sealing points 16, 18 are also effective directly for fixing the sealing device portion 11 as a whole in a stationary manner. An additional mechanical fixation of the sealing device portion (sealing device wall) 11, which maintains the sealing device portion in position, i.e., in a gas-tight contact with, for example, the wall 20, may possibly also be necessary in case of a seal at the first and/or second sealing point 16, 18.

[0023] The gas-tight sealing device 10 brings about a gas-tight enclosure of the connection point between the line element 14 and the coupling element 12. In case of a mounted gas-tight sealing device 10, the gas being discharged in case of a leaky connection of the line element 14 to the coupling element 12 reaches only the interior of the gas-tight sealing device 10. The gas can possibly flow off from there possibly via remaining gaps between the coupling element 12 and the wall 20, as this is shown in the view in FIG. 1 by the arrows originating from the end of the line element 14, which end is connected to the coupling element 12.

[0024] The view in FIG. 2 shows an embodiment of the gas-tight sealing device 10 according to FIG. 1, in which this has a vent port for a removing line element, which will hereinafter be called a flexible tube 22 for distinction from the line element 14, but without abandoning a continued general validity. Gas that is discharged to the coupling element 12 in case of a leaky connection of the line element 14 to the coupling element 12 and first enters the interior of the sealing device 10 can flow off via the flexible tube 22. The vent port and a possibly connected flexible tube 22 generally act as a vent of the gas-tight sealing device 10.

[0025] The view in FIG. 3 shows an embodiment in which the gas-tight sealing device 10 is connected to the line element 14, on the one hand, and to the coupling element 12, on the other hand, and thus ensures a gas-tight enclosure of the connection point between the line element 14 and the coupling element 12. The explanations given in connection with FIG. 1 and FIG. 2 correspondingly apply to the embodiment of the gas-tight sealing device 10 shown in FIG. 3, so that unnecessary repetitions can be eliminated here. Contrary to the embodiment shown in FIG. 1 and FIG. 2, the gas-tight sealing device 10 adjoins, extending in a gas-tight manner all around, the coupling element 12 at a second sealing point 18. The gas-tight sealing device 10 adjoins, extending in a gas-tight manner all around, the line element 14 at a first sealing point 16, in a manner similar to the embodiment shown in FIG. 1 and FIG. 2.

[0026] The view in FIG. 4 shows an embodiment, in which the gas-tight sealing device 10 encloses a plurality of connection points between a coupling element 12 and a respective line element 14 in a gas-tight manner. The gas-tight sealing device 10 has a number of sealing points (first, second, and further sealing edges) 16 corresponding to the number of line elements 14, and the gas-tight sealing device 10 adjoins, extending all around in a gas-tight manner, the respective line element 14 at these sealing points 16. In the embodiment shown, this has a basically optional vent port, and a flexible tube 22 is connected, likewise optionally, via this vent port, to the gas-tight sealing device 10 for removing gas escaping at a connection point between the coupling element 12 and a line element 14 and collected by means of the gas-tight sealing device 10.

[0027] It applies to all the embodiments shown that the respective sectional views show only one section of the wall (sealing device portion) 11 of the gas-tight sealing device 10 and that the gas-tight sealing device 10 is accordingly complemented at right angles to the drawing plane in both directions to obtain a closed housing comprised of the wall (sealing device portion) 11. The gas-tight sealing device 10 is preferably a one-piece plastic part. The gas-tight sealing device 10 is optionally elastic and is made, for example, in one piece from a material acting as a seal at the edge, for example, an elastomer. A multipart gas-tight sealing device 10 may also be provided. The gas-tight sealing device 10 has one or more sealing points with seals or bonds for a gas-tight connection of one of the individual parts to the other individual part.

[0028] The gas-tight sealing device 10 according to FIG. 1, FIG. 2 and FIG. 3 may have a cylindrical basic shape, with a vertical axis parallel to a coupling element 12 fully or partially enclosed in the gas-tight sealing device 10. As an alternative, the gas-tight sealing device 10 may also have a polygonal basic shape, for example, a cubic or cuboid basic shape. The outer shape of the gas-tight sealing device 10 is, in principle, freely selectable and may also have any desired degree of complexity, for example, in view to the smallest possible volume and hence the smallest possible space requirement, and follow, for example, the boundary lines of the respective enclosed components (coupling element 12, line element 14) encapsulated in the interior of the gas-tight sealing device 10.

[0029] The configurations according to FIG. 1 through FIG. 4 act, for example, as gas removal points. Based on the gas-tight enclosure of the connection point or of each connection point, which is/are, in principle, subject to the risk of leakage, by means of the gas-tight sealing device 10, the gas removal point as a whole is enclosed in a gas-tight manner. The gas removal point (site) may thus be positioned, in principle, as desired, and the gas removal site may also be located, for example, in the vicinity of electrical or electronic circuits or consumers.

[0030] Individual aspects of the description being filed here, which are in the foreground, can thus be briefly summarized as follows: A gas-tight sealing device 10 is provided, which comprises a sealing device portion (wall) that encloses at least one part of a coupling element 12 or a part of a wall 20 with the coupling element 12, on the one hand, as well as at least one section of a line element 14 connected to the coupling element 12, on the other hand, wherein the gas-tight sealing device 10 is connected, extending in a gas-tight manner all around, to the line element 14 at a sealing point (sealing edge) 16, wherein the sealing device 10 is connected, extending in a gas-tight manner all round, at another sealing edge 16 and/or 18 to the coupling element 12 or to a wall 20, in or at which the coupling element 12 is mounted, and wherein the sealing device portion (wall) 11 encloses a volume defined by the geometry of the gas-tight sealing device 10 in a gas-tight manner between the sealing edges (such as between the first sealing point 16 and the second sealing point 18). The sealing device 10 acts as a single partitioning device, contrary to the partitioning in individual areas, as it is provided in the current state of the art.

[0031] While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
