Definitions

  • the invention relates to a fan cap made of plastic material for rear ventilation of roofs in the ridge, hip or ridge area, with a fastening area, with an edge area and with an intermediate area connecting the fastening area and the edge area, the intermediate area having air passage openings and the edge area on the roof side has the cap length extending, resilient sealing member and the sealing member has the structure of a fine thread brush with a plurality of elastic brush threads arranged in at least largely flow-tight packing.
  • Such a fan cap is already known from DE-A-38 13 094.
  • the basic advantage of a fan cap with a sealing element designed as a fine thread brush is that the fine thread brush can easily adapt to the various gap shapes between the roof covering and the fan cap, without impairing the airtightness, especially in the case of sharp-edged and particularly pronounced transitions.
  • the fine thread brush is firmly connected to the edge area of the fan cap, so that the fine thread brush is an integral part of the fan cap.
  • the object of the invention is to design and develop a fan cap of the type mentioned at the outset in such a way that storage, packaging, transport and installation problems are substantially reduced or decisively simplified.
  • this object is essentially achieved in that the sealing member is releasably connected to the edge region. Due to the releasable fastening according to the invention there is the advantage that the sealing member has to be connected to the relevant fan cap practically only at the respective construction site, so that depending on the required dimensions of the sealing member only different sealing members in connection with only a single type of fan cap or more precisely, a fan cap base body must be kept in stock and then the required combinations can be put together on site.
  • the preferred embodiments of the releasable fastening of the sealing member to the edge region specified in the subclaims effectively prevent the fine thread brush from falling off or loosening from the edge region.
  • Detaching and dropping off of sealing elements from the edge area can occur relatively frequently in known fan caps if the sealing elements are glued to the edge area, which is, however, the rule.
  • the sealing member may come off and fall off from the edge area when the fan cap is being transported. It is particularly disadvantageous if a sealing member only comes loose after the fan cap has been installed, since then repair or replacement of the fan cap is associated with a relatively large amount of effort.
  • a fan cap 1 which comprises a fastening area 2, a roof-side edge area 3 and an intermediate area 4, 4 air passage openings 5 being provided in the intermediate area and 3 support elements 6 being provided in a known manner in the edge area 3.
  • a sealing member 7 in the form of a fine thread brush made of a plurality of brush threads 8 is attached.
  • Fine thread brushes designed according to the invention can be used with all types of fan caps, so that the fan cap with fine thread brush indicated in FIG. 1 is only to be regarded as an example of such fan caps.
  • the seal according to the invention in the form of a fine thread brush can accordingly be used for ridge, hip or ridge areas, but also for throat areas.
  • Fig. 2 shows an embodiment in which the sealing member 7 is attached in the form of a fine thread brush to a carrier part 9 and has brush threads 8 of different lengths, so that the fine thread brush has a wedge-shaped area 10 at its end facing away from the carrier part 9.
  • the fine thread brush is substantially wedge-like over its entire height, and the carrier part 9 has a recess 11, in the area of which a coupling or connection to the associated fan cap 1 is preferably possible.
  • the fine thread brush consists of several areas of brush threads 8 of different lengths, with graded transitions between the individual areas.
  • three brush strip strips can be combined with one another in this case, as will be explained in more detail below.
  • the carrier part 9 is connected to a fastening part 12 which encloses an acute angle with the carrier part 9.
  • FIG. 5 An arrangement analogous to FIG. 4 is shown in FIG. 5, in which case the fine-thread brush is designed in the form of an oblique wedge with a blunt end.
  • FIG. 6 shows an embodiment of an arrangement according to the invention essentially corresponding to FIG. 4, in which case clamping or dome knobs 18 are attached to the fastening part 12, which preferably have lateral clamping ribs.
  • the sealing member 7 can be connected in a simple manner to the associated fan cap 1, ie to the edge region 3, via these dome knobs 18 since it is only necessary to insert the dome knobs 18 into corresponding receiving slots and to snap them into place.
  • the dome knobs 18 can simultaneously form support members for ridge caps.
  • Fig. 7 shows a schematic representation to explain a preferred way of producing the fine thread brush according to the invention.
  • a first layer of brush threads 8 is placed on a tensioned holding element 14 in the form of a wire, rod or the like, and further layers are then applied adjacent to this first layer.
  • the carrier part 9, which in this embodiment is designed as a galvanized sheet is bent around the holding element 14 in such a way that the brush threads 8 are enclosed in the carrier part 9 in the region of the holding element 14, so that the fine thread brush shown in FIG. 8 results.
  • the fine thread brush can also be produced by first placing the brush threads on a horizontally lying strip of zinc sheet, metal strips or strips of other materials. A holding element in the form of a wire or rod is then placed in the center of the brush threads placed on it and the entire arrangement is then crumbled.
  • the clamping is somewhat more pronounced in the area of the exit of the brush threads 8 from the carrier part 9, so that the smallest width of the fine thread brush results at this point, while the brush threads 8 fan out somewhat towards the free end.
  • the width of the fine thread brush according to a preferred embodiment is approximately 2.5 mm, it being essential that the individual brush threads 8 have diameters in the range from 0.10 to 0.40 mm and preferably in Have a range from 0.15 to 0.35 mm, which is equivalent to the fact that the fine thread brush according to the invention has a large number of brush threads 8 per running length unit.
  • the brush threads 8 can consist of plastic material, in particular polypropylene or nylon. However, it is also possible to use fine metal threads and natural fibers of vegetable or animal origin, and in principle mixtures of these different fibers can also be advantageous.
  • the brush threads 8 already provide the necessary flow tightness when they are straight, due to their tight packing, but these brush threads 8 are preferably deformed in their longitudinal plane, in particular corrugated, since this results in mutual interlocking, which also contributes to that no air breakthrough can occur even with strong wind pressure. This results in the best safety against flying snow and driving rain.
  • brush threads 8 with lengths of 30, 40, 50, 60, 75, 97 and 105 mm are provided, and a major advantage of the invention is that these different brush strips must first be connected on site to the associated fan cap 1, which is readily possible since a corresponding coupling with the fan cap 1 is possible in the simplest way via the carrier part 9.
  • the squeeze fastening of the brush threads 8 explained with reference to FIGS. 7 and 8 represents a particularly simple and preferred way of realizing the carrier part 9 for the fine thread brush, but it is also possible to fix the brush threads 8 at their fastening-side end in another way, provided that it is always the necessary tight packing guaranteed and ensured that the inflow tightness can no longer be guaranteed in the required manner by a tuft arrangement of the brush threads, for example.
  • FIG. 9 shows a preferred coupling option between the fine thread brush and the edge area 3 of the fan cap 1.
  • a tab part is shown that is used to implement a sliding guide 15.
  • inserted insertion corners 20 are provided.
  • the right part of the illustration in FIG. 9 shows the fan cap 1 with an outwardly extending spoiler 19 and an inwardly angled edge region 21.
  • the free ends of the angled edge region 21 and the sliding guide 15 on the brush side are again angled inwards so that the fine thread brush is prevented from escaping on this U-shaped receptacle.
  • the fine thread brush is preferably introduced in the form of a sliding process, the insertion of the fine thread brush or the brush strip strip to be carried out in the longitudinal direction 1 being facilitated by the corners 20 that have been set up.
  • This embodiment of a coupling between the brush strip strip and the fan cap 1 is distinguished by a particular simplicity and also by an inexpensive production, because the fan cap 1 itself forms part of the sliding guide 15 mentioned with its edge region.
  • the fan cap 1 according to the invention is extremely temperature-resistant, taking into account the respective choice of material and due to its construction with a large number of separate individual elements, is also flow-tight under difficult circumstances and, above all, extremely adaptable in relation to the respective sealing problem. Due to the detachable and adaptable fine thread brush, every roofing material is completely sealed without leaving open areas at corners and arches through which driving rain and / or flying snow can be introduced. Furthermore, there is no danger that - as can be the case with conventional foam seals - the sealing material is used for nest building and the sealing function is thereby deteriorated.
  • the brush threads 8 can preferably have a circular, elliptical, triangular, or square or rhombic cross section.
  • the cross-sectional profile over the length of the brush thread can be cylindrical or conical.
