Description

The invention relates to a rollable ridge and ridge ventilation element in the preamble of the type described in claim 1.

Such ventilation elements, hereinafter also referred to as fans, are located on their central part attached to a ridge or ridge slat and seal the gap between this slat and the Roof tiles from a roof, with their outer edge areas on the Cover plates come to rest.

A ventilation element is known from DE-A-40 01 766. This fan is made of a non-woven fabric and pleated in the area of its outer edges, so Can be enlarged in size to nestle into the valleys of the roofing slabs to be able to. The necessary air exchange between the areas below and above of the fan is realized in that air-permeable non-woven material is used becomes. Since the nonwoven material must be impermeable to water but permeable to air, points this fan only has very small air passage pores in the nonwoven fabric Dusting over time and becoming airtight, causing the ventilation function can no longer be fulfilled.

Another ridge and ridge ventilation element is known from EP-A-0 117 391. It exists from a rigid middle part with adjacent side parts made of comb-like elastic Teeth are built on which a non-woven material is attached in a pleated form. The Side parts in turn nestle against the roofing slabs, thereby the sealing is achieved. In the stiff middle part of this fan are next to the support area ventilation openings are provided for the ridge or ridge through which the air can pull up from the roof structure. This rigid ventilation element is disadvantageous not rollable and must be manufactured and sold by the meter, whereby storage and distribution costs are increased. Furthermore, the manufacture of such an element is expensive, and its uses are limited to certain Roof tile shapes limited.

Ventilation elements with the features of the preamble of claim 1 are from known from DE-U-295 04 548 and from EP-A-0 712 973. However, these elements show Roofing tile conformability problems, namely because of their high transverse rigidity.

It is therefore the object of the invention, a ridge and ridge ventilation element and a To provide a process for its manufacture that has the disadvantages of the prior art technology overcomes. In particular, a ventilation element is to be created that can be rolled up, provides a permanent good ventilation of the roof structure for different roof tile designs can be used and manufactured inexpensively, can be stored and transported.

This object is described by the characterizing part of claim 1 Features of the ridge and ridge ventilation element according to the invention solved.

The subclaims relate to preferred embodiments of the present invention.

According to the present invention can be produced inexpensively in the extrusion process, a fan that ensures permanent good ventilation by means of the ventilation openings. These vents cannot be blocked by dust. The material from which the Fan is made, is both air and water impermeable and guaranteed thus a complete seal of the gap between the roofing and the Ridge or ridge slat. Furthermore, the fan manufactured in the extrusion process is flexible and rollable and can therefore be in great lengths with good transportability and storage to provide. It is also very adaptable due to its flexibility and can be used for various roof shapes.

In the ventilation element according to the invention in the section of the ventilation element where the ventilation strip adjoins the central strip, and / or in the section where the ventilation strip adjoins the sealing strip, in the longitudinal direction of the ventilation element a bending zone with one opposite adjacent areas of reduced material thickness. The side parts of the ventilation element after placing the median strip on the ridge or ridge slat, if possible their own weight fall down and into the valleys of the roofing slabs mold. By means of the bending zones described above, which run along the fan a lower bending stiffness is achieved in the transverse direction of the fan, so that the Nestling of the sealing strip on the roof tile shape is facilitated.

According to a preferred embodiment, in a fan according to the invention the ventilation openings in the ventilation strip protruding towards the top Deposits formed, the outer edges of which form water protection edges. These water protection edges prevent water from entering the roof through the ventilation openings penetrates, and ensure a good drainage of the water on the top of the fan.

The material of the fan is preferred in the area of the deposits compared to the surrounding ones Areas thickened, and advantageously the edges of the ventilation openings reinforced with beads. These configurations prevent that when the Ventilation element, the deposits with the ventilation openings and the water protection edges be pressed in by surface pressure. To one against such an impression To provide further protection can also on the ventilation strip to the top of the Vent element protruding spaced spacers may be provided.

In the case of a fan according to the invention, it advantageously runs in the section of the Ventilation element, where the ventilation strip adjoins the sealing strip, one for Spoiler edge protruding from the top of the fan in the longitudinal direction of the ventilation element. The outside air that flows through the ventilation duct of the roof tile valleys overflows this spoiler edge, which creates an additional vacuum above the fan, which leads to improved ventilation of the roof structure through the ventilation openings.

Adhesives, in particular, are suitably attached to the underside of the sealing strip Adhesive beads, arranged, the area of the sealing strip where the adhesive are arranged, is advantageously roughened. The adhesives are used in the Valleys of the roof tiles recessed sealing strips to fix there to an optimal Obtain sealing effect. The roughening of the sealing strips causes a better one Stop the adhesive.

Glue is particularly preferred up to the valleys in the pleating of the sealing strip on all sides applied, which improves the stability within the pleating. Likewise, Advantageously, good gluing into the valleys of the roof tiles or roofing slabs into it.

The ventilation element preferably consists of a, in particular modified, PVC material, which, thanks to additives, is weatherproof and especially resistant to UV light is made. Especially with the sealing strip that is partially exposed to the outside Such a design brings advantages in terms of service life.

There are several possible ways of improving the stability of the sealing strips. First, stabilizing in the material of the sealing strip during extrusion malleable elements are introduced, e.g. from an expanded metal mesh or from in There are wires or flat strips extending in the longitudinal direction of the ventilation element. On the other hand, a stabilizing can also be on the underside of the sealing strip malleable element, in particular a flat strip, in the longitudinal direction of the fan runs, be attached.

In a preferred embodiment, a ridge and ridge ventilation element according to the invention characterized in that the sealing strip forms a separate component which with the middle part consisting of the median strip and the ventilation strip is connected. By providing such a multi-part embodiment, it will now possible different shapes and materials of sealing strips in the inventive Ventilation element to use and so an optimal in each case To provide fan shape for the various applications.

According to an embodiment of such a fan, the sealing strip is in the region of the Connection point with the middle part of its material reshaped to ensure a safe Connect.

The sealing strip can at least in the area of the connection points with the middle part be designed as a flat strip, which makes the connection easy during extrusion can be manufactured.

To ensure a firm connection, it is advantageous if the sealing strip in the Area of the connection point with the central part in the longitudinal direction of the ventilation element has spaced connecting bores. The material that is still soft during extrusion of the middle part can penetrate into the connecting bores in the sealing strip and thus one Cause claws between the sealing strip and the middle section.

According to another embodiment, the sealing strip can also be in a pleated form be molded into the material of the middle part.

The sealing strip can ver in different ways with the material of the middle part be bound. In addition, welding, gluing, riveting, folding or Putting or reshaping when extruding into question.

The material for the separate sealing strip can vary depending on the usage requirements to get voted. In particular, lead, aluminum, copper, fabric material Brushes or similarly deformable material can be considered as the material for the sealing strip.

For a general explanation of the operation of a ridge and Burr ventilation element is now first referred to FIGS. 7 and 8. The 8 shows a side view of a partially cut roof ridge, a ventilation element, that is rolled out of a roll 20 and laid on a ridge batten 18. The Ventilation element is hereinafter referred to as fan 1. The fan 1 lies with his Middle part 6 on the ridge 18 and covered with the ventilation strip 7 and Sealing strip 8 the gap between the roofing panels 17, 19 and the ridge slat 18. The fan 1 is attached to the central part 6 on the ridge 18, e.g. nailed.

The sealing strip 8 of the fan 1 hugs the shape of the roofing panels and thus takes on the waveform through the valleys 19 and the apex 17 of the Roofing slabs is specified. The ventilation openings are in the ventilation strip 7 9 of the fan 1 incorporated, through the air from the lower area of the roof ridge after can circulate above.

Fig. 7 shows a cross section through a ridge on which the invention Fan 1 is moved. It can be seen here in particular how the ventilation strip 7 is free is between the ridge batten 18 and the roofing panels 17, 19 to a good To ensure air circulation. At the bottom of the ventilation openings 9 in their Depositions 11 in FIG. 7 are also those running along the fan 1 in the longitudinal direction To see spoiler edges 13, the function of which will be explained in more detail below.

1 and 2 show a cross section and a plan view of an embodiment of a fan 1 according to the invention. The median strip 6 of the fan 1 is the part which is placed on a ridge or ridge slat. The ventilation strip connects to this 7 with the ventilation openings 9 which protrude upwards Sections 11 are molded. Run to the left and right of the sections 11 along the fan 1 bending zones 5, the material of which compared to the surrounding Material is made thinner. The fan 1 bends slightly at these bending zones 5 its own weight down, whereby the adjoining the ventilation strip 7 Sealing strip 8 can nestle well into the valleys of the roofing slabs. The Sealing strip 8 is pleated, as can be seen in FIGS. 1 and 2, so that it is at the adaptation to the waveform of the roof can increase in area. Around to allow areal enlargement is also possible to others Process for making a wave or fold shape or using the seal to design strips like brushes.

The deposits 11, in which the ventilation openings 9 are pronounced, form on their Outer edges of water protection edges 14. This ensures that on the fan 1 located water runs off without in the ventilation openings 9 and thus in the roof interior to penetrate. Between the paragraphs 11 are shown in the here rectangular shape transverse channels 10 are formed, which also for a good flow of Provide water and form further water protection edges 14.

The material of the fan 1, which is modified PVC in the present case, by Suitable additives are made flexible and weatherproof, is in the area of sediments 11 thickened. This configuration allows simple formation of the settlements 11 and stabilizes their shape against being pressed in when the fan rolls up 1.

In particular, additives are added to the fan material that are exposed to it Make UV light resistant.

3 and 4 show a further embodiment of the fan according to the invention. in the Difference to the fan shown in FIGS. 1 and 2 are in that according to FIG. 3 and 4, the deposits 11 are formed in a circular stepwise manner. They form graded Water protection edges 14. Another difference concerns the provision of spacers 15 in the fan shown here. These spacers 15 are for Molded elements bulged out on top of the fan that are slightly higher than that Depositions 11. When rolling up the fan according to this embodiment, prevent Spacer 15 that a surface pressure is exerted on the deposits 11 and protect them from undesired impressions. A cross section through a Deposition 11 with a ventilation opening 9 is shown in Fig. 5. Outside at the deposition 11 the stepped water protection edge 14 can be seen.

6 shows a cross section through a spacer 15.

Finally, the fan according to FIGS. 3 and 4 differs from that of FIG. 1 and 2 still in that between the shoulders 11 and the sealing strip 8 on both sides a spoiler edge 13 running along the fan is formed in each case. This spoiler edge 13 allows better ventilation of the roof structure because of the ventilation duct the roof tile valleys flowing air must cross the spoiler edge, causing itself a negative pressure above the ventilation openings 9 results. Enlarged by this vacuum the volume flow of the air flowing out through the ventilation openings 9; ventilation is improved.

9 shows a further design option for a sealing strip ventilation element according to the invention. The symmetrical fan is here, just like in 10 to 16, 19, 20 and 23, shown as a half section in cross section. In the 9 is a stabilizing material in the sealing strip 21 of the fan 22 introduced. Such a stabilizing material 22 can e.g. an expanded metal grid may be, however, other stabilizing materials with the same effect be used, as will be explained later.

In Fig. 10, the sealing strip 21, which is still shown in Fig. 9 is not pleated, is now shown in pleated condition. On the underside of the sealing strip 21 are adhesive beads 37 attached with which the sealing strip 21 is located on the top of the Roof cover plates can be attached. Thanks to the stabilized shape and firm adhesion a very good sealing effect can be achieved. 11 shows again in the Top view of an expanded metal grid 22 incorporated into a sealing strip 21.

12 to 14 different possibilities are shown, stabilizing elements in the sealing strip. So are in the sealing strips shown in Fig. 12 Wires 24 running along the fan are shown. The sealing strip shown in Fig. 13 has flat strips 25, for example made of expanded metal, which like the wires 24 of the Embodiment according to FIG. 12 are incorporated into the material of the sealing strip.

Fig. 14 shows an embodiment in which a flat strip 26 suitably comprises Expanded metal, attached to the outside of the sealing strip at the bottom. This flat strip too 26 gives the sealing strip greater stability after installation.

The embodiments of FIGS. 12 to 14 are also provided with adhesive beads 37. To a removable plastic film tape (not shown) are applied so that the fan roller does not stick during transport.

15 shows a preferred embodiment of a fan 2 according to the invention, in which the cover strip 27 consists of a separate component, which during the manufacturing process is connected to the central part 38. The sealing strip 27 is in here shown in an unpleated form. It can be used for all purposes suitable materials. Examples of this are lead, aluminum, copper, fabric material, Brushes and similarly malleable material.

The sealing strip 27 is unpleatedly connected to the central part 38 in that it is enclosed by this at the junction. 16 shows the sealing strip 27 in its pleated form, which after connection to the central part 38 is awarded. In the area of the connection point, the sealing strip 27, as in FIG 17 is shown in detail, a connecting bore 29. In the preparation of the connection penetrates still soft material of the middle part 38 by extrusion the connecting bore 29 of the sealing strip 27 forms an undercut, and ensures a good connection thanks to a claw effect.

FIG. 18 shows the pleating at various points on the sealing strip 27 from FIG. 16. In the left part, designated P2, the sealing strip 27 is completely pleated, while in the transition area, indicated by P1, a less highly developed one There is pleating. With this fan 2, the sealing strip remains in the area of the connection point with the central part 38 unpleated.

Another embodiment of a ventilation element according to the invention as fan 3, is shown in FIGS. 19 to 22. From Fig. 19 it can be seen that at this fan 3, as with the fan 2, the sealing strip 30 only in its outer Area is pleated, while section 31 is at the junction with the central part 38 remains unpleated. The connection of the sealing strip 30 to the middle part 38 takes place as with fan 2 through a plastic enclosure.

The fan 3 is reinforced in its central section 38 at certain points in the material. 19 shows in particular the material reinforcement by beads 32 at the ventilation opening 39 can be seen. Again, spacers 33 are arranged on the middle part 38. The Position of the reinforcements, i.e. the beads 32 and the spacer 33 is shown in FIG. 20 clearly. 21 shows the step-like configuration of the beads 32, the one Form water protection edge; 22 is a thickened spacer 33 in cross section shown.

23 and 24 show a further embodiment of a ventilation element 4 according to of the present invention. The extrusion connection 35 of the central part 38 with the Sealing strip 34 of the fan 4 is made in this embodiment so that the Sealing strip 34 in a fully pleated shape in the outer edge of the central strip 38 is extruded. This creates a very durable connection Cross section A-A (see Fig. 23) is shown in Fig. 24 and in which the edge material of the Middle part 38 is designated by the reference numeral 37. This extrusion connection too can be a claw by providing connection holes (not shown) or others effecting elements are reinforced. Instead of extrusion molding can also be overmoulded in a simple injection molding process on a spraying machine.

A ventilation element according to the invention is rolled up in lengths of, for example, 5 m manufactured and delivered. The manufacturing process for multi-part according to the invention Ventilation elements basically have two variations:

The first variation, in which a fan according to FIGS. 15 to 22 is produced, is the flat sealing strip is connected to the central part and at least later partially pleated. Advantageously, an unpleated remains at the connection point Part with a width of about 15 mm.

In the second variation, a fan is produced, which according to FIGS. 23 and 24 is trained. The pleating runs across the entire width of the sealing strip.
