Description

The present invention relates to a ridge and / or ridge ventilation element, whose middle part on a ridge or Rattlatte is attachable, and on both sides of the middle part adjacent side parts with their outer edge areas can be placed on roof coverings and between their edge areas and the middle part is air-permeable are.

Such a ridge and / or ridge ventilation element is made became known to the German utility model G 94 16 291.3.

Ridge and / or ridge ventilation elements are in the roof area used to between the ridge or ridge and the Sealing roof coverings remaining gap. This There is a gap between the ridge or ridge slat and the roof covering to the right and left of the ridge or ridge slat in the longitudinal direction of the roof ridge. Through the ridge and / or ridge ventilation element the ingress of rainwater, snow, Bugs or debris in the roof interior if possible prevented. At the same time through the ridge and / or ridge ventilation element adequate ventilation of the roof interior be made possible to protect the roof structure against rotting To protect damage.

The well-known ridge and / or ridge ventilation element is in one piece made from a soft, open-cell foam. Due to its fixed geometric dimensions the gap between the ridge and roof covering be bridged. Then ridge tiles are placed over the Ridge ventilation element arranged so that the edge areas of the ridge ventilation element sealing against the roof covering be pressed. Problems now arise when that Ridge ventilation element the gap between the ridge and Roof covering cannot cover as intended. In these Cases occur sealing problems in the peripheral areas between the roof covering and ridge tiles. It can too Ventilation problems from improper attachment of the Ridge ventilation element result because the air-permeable Area of the side part may be on the ridge or comes to rest on the roof covering. The breathable For this reason, the area can no longer Perform the ventilation function of the roof interior.

But when it comes to erecting the roof structure, it always happens before that the distances between ridge batten and roof batten (or roof covering) are dimensioned differently. Also it can happen if the roof battens are not precisely aligned, that the distance between the ridge and the roof covering within the same roof truss is subject to fluctuations.

A possible solution to these problems could be that the craftsman ridge ventilation elements different Size used. But this is expensive to perform and makes the seal between the roof covering and the ridge tiles more expensive.

From DE 40 01 766 C2 there is a ridge and / or ridge ventilation element known that in the above manner in Ridge area can be attached. The side parts of this Ridge ventilation elements consist of a nonwoven or Fabric that matches the shape and dimensions of the ridge ventilation element firmly pretends. Consequently, this is also ridge and / or Ridge ventilation element unable to differentiate Cover the distances between the ridge batten and the roof covering can.

With one in the German utility model 295 01 242.0 described sealing strip goes a median over two longitudinal, one between each Section of predetermined length beads in a Hard shoulder across. Because of this training, the Sealing strips preformed snap edges, which each to different ridge and / or ridge slat widths are customizable.

Single or multiple bends on a vent are designed according to the teaching of DE 38 25 348 A1, allow the formation of stall edges.

Longitudinal folds of a ridge ventilation element known from GB 21 55 516 A. form groove flanks of a holding groove in the other components of the ridge ventilation element attached can be.

The present invention is based on the technical problem to present a ridge and / or ridge ventilation element, by using different sized spaces between the ridge batten and the roof covering can that between the ridge and roof covering Air circulation is possible and the area between ridge tiles and roof covering is easy to seal.

According to the invention, this technical problem is solved by that the side panels in their breathable area and / or in their outer edge areas with in the longitudinal direction of the ridge and / or ridge ventilation element Longitudinal folds are provided, which create a storage area, so that the ridge ventilation element in its side Extendable length is designed.

By forming the longitudinal folds of the invention Ridge ventilation element, the ridge ventilation element can be varied to different distances between the ridge and Roof covering react. The folds in the longitudinal direction of the Ridge ventilation element ensure that the lateral extension the ridge ventilation element adjusted accordingly can still be the area necessary for ventilation of the side part is given. With one opposite the lateral length of the ridge ventilation element smaller distance between ridge batten and roof covering can Ridge ventilation element creates new folds so the ridge ventilation element is shortened laterally accordingly. For this reason, the edge area is always sealed on the roof covering while the air permeable area of the side part of the ridge ventilation element optimal aligned between the ridge batten.

Tolerance fluctuations through the use of different Ridge or ridge slats and their aligned fastening therefore have an influence on one another Functional use of the ridge ventilation element.

According to the invention, the longitudinal folds can be designed in this way be that corresponding sections of the side part of the Ridge and / or ridge ventilation elements towards the ridge tile are arranged one above the other or erected side by side are so that the longitudinal folds point to the ridge tile. The individual longitudinal folds also do not have to have sharp edges be formed, but can also be folded with curves his. It is important that surface areas of the side part fold-rock-like structure accordion-like or can be pushed apart. Therefore, according to the invention also understood by the formation of longitudinal folds, that individual areas of the side parts of the ridge ventilation element Form wave crests or wave troughs. This wave-like folding has the advantage that the ridge ventilation element adjust variably across its longitudinal direction leaves. When pulling apart, the relative increases Angle of adjacent folds or waves and it lengthens this section of the ridge ventilation element without Material stresses occur.

In a particularly preferred embodiment of the invention Ridge ventilation element have the outer Edge areas on a longitudinal fold leading to one of the roof covering groundbreaking flow edge is erectable. In Connection with the possibility of the ridge ventilation element to be able to pull apart as needed, one such flow edge at any point with any Form the size between the roof covering and the ridge tile. The flow edge can have a small extent protrude up to the ridge tile, but it can also fit the ridge tile. The flow edge prevents Incoming air snow, moisture or debris inside can carry. The air-permeable area of the ridge ventilation element therefore always remains dry and flowable, so that air circulates through the air permeable area can.

In a further embodiment, the side parts are made in its air-permeable area made of individual filaments, which are connected to form a formable grid or fabric are. By using the individual filaments an area of the ridge ventilation element is created, through which air can flow with high efficiency. Even if partial areas of the side parts with a lattice structure air can still be folded over each other Flow out of the roof interior. In contrast becomes the state of the art through the predetermined grid openings always a defined possibility for air flow guaranteed.

With regard to the manufacture of the ridge ventilation element according to the invention it is preferred that the outer edge regions the side parts by strengthening the grid areas are formed. As a result, the entire ridge ventilation element except the middle part of a net or grid manufactured. For sealing between roof covering and ridge tiles it is advantageous that the outer edge areas consist of the deformable grid. this makes possible it to adapt the edge areas to the contour of the roof covering and form a better seal. Through the Solidification of the lattice areas is achieved that the openings eliminated between the individual filaments, one Sealing function can be exercised, but the deformability of the grid remains intact.

In a further development of this embodiment, the Solidification of the edge areas in a coating and / or Cover the grid areas with a thin-walled film. On the one hand, the thin-walled film fulfills the task of To close grid openings of the grid areas and on the other hand to increase the stability of the edge areas. Therefore can the edge areas on different roof contours adapt well and allow the effect of a seal.

When this training is first implemented, the Foil made from a light metal. It is e.g. conceivable, the mesh fabric on both its top as well cover on the underside with an aluminum foil. The two aluminum foils can be glued together, so that the malleable mesh or fabric is wrapped in an aluminum sheath is embedded. The malleability through the The lattice structure is retained even if the aluminum foil is applied. Of course you can also use foils other metal alloys can be used.

In another realization of the coating of the lattice structure the film is made of plastic. The usage of plastic has the advantage that the ridge ventilation element in addition to its inexpensive manufacture is made of a weatherproof material.

The grid area of the ridge and / or ventilation element is preferably by threads made of an elastic plastic or metal. Through such threads (filaments) the side part of a ridge ventilation element can also be used to the design by the inventive Deform longitudinal folds even further to create a three-dimensional Train structure that adapts well to those to be worked on Can adjust roof area. In particular, the individual Filaments even after the ridge ventilation element has been attached still to be edited. Similar to covering one Tennis racket can move the filaments against each other to correct, if necessary, that the Air permeability is impaired.

In a further preferred embodiment, this is Ridge and / or ridge ventilation element can be rolled up. this has the advantage that the ridge and / or ridge ventilation element can be rolled up into larger rolls that are very easy and inexpensively stored, transported and in the roof area can be attached. You can roll with one Make the length sufficient for an average roof. By rolling off the ridge ventilation element the craftsman can easily use the ridge ventilation element on the Fasten the ridge batten and the roof covering.

As an alternative to the roll-up version, the invention Ridge ventilation element also through to it Wrinkles formed in the longitudinal direction to form an endless ridge ventilation element be merged. The ready to transport The ridge ventilation element is then not cylindrical Roll form before, but has cuboid geometry. It can then be stacked better. The ridge ventilation element can then be placed in a rectangular "dispenser box" and as strips in corresponding sections removed and separated as required.

The ridge ventilation element can be attached particularly well just perform when the bottom of the midsection and / or the outer edge regions of the side part are provided with an activatable adhesive layer. By the Peeling off a protective film over the adhesive layer can do that Ridge ventilation element can be glued. So that's it permanent tight sealing of the gap between the Ridge lath and the sloping roof covering easy perform. For gluing the ridge ventilation element any adhesive techniques and adhesives are conceivable under also the use of hot glue. Hot glue connects cannot be detached from the plastic of the ridge ventilation element, so that despite the occurrence of high temperatures a secure, positive connection in the roof area permanently given is.

Further features and advantages of the invention result from the following description of an embodiment the invention, based on the drawing, the essential to the invention Shows details, and from the claims. The single ones Features can be used individually or in several any combination in an embodiment of the invention be realized.

The invention is shown schematically in the figures, so that the essential features of the invention can be seen well are. The illustrations are not necessarily to scale to understand.

1 shows a ridge ventilation element 10, as is arranged, for example, in the ridge area of a roof structure.

The ridge ventilation element 10 has a central part 11 and adjoining side panels 12. When attached to the Ridge ventilation element 10 is the middle part 11 with his Bottom 13 on the top 14 of a ridge batten 15 on. On its underside 13, the middle part 11 has one Adhesive layer so that the middle part 11 on the ridge 15th is permanently and securely fixed.

Air-permeable regions 16 adjoin the central part 11 of the side part 12. Have the air-permeable areas 16 two in the longitudinal direction 17 of the ridge ventilation element 10 longitudinal folds 18 and 19. Due to the The area 16 can be formed by the longitudinal folds 18 and 19 are folded apart transversely to the longitudinal direction 17. The Extension of the ridge ventilation element 10 transversely to the longitudinal direction 17 can therefore be changed. Through training still further longitudinal folds 18 and 19 can this Enhance function. There are different ones Distances between the ridge batten 15 and a roof covering Bridge 20.

The roof covering 20 is made of individual roof covering plates formed and lies on roof battens 21 and 22. The Roof battens 21 and 22 are attached to the rafters 23 and 24. The ridge 15 is above the rafters 23 and 24 arranged with the help of a ridge slat holder 25.

The middle part 11 of the ridge ventilation element 10 goes into the air-permeable area 16, to which in turn a not air-permeable edge region 26 adjoins. The side part 12 is made up of the air-permeable area 16 and the not air-permeable edge region 26 together. The edge area 26 is also foldable so that its length can also be varied in the direction of arrow 27. additionally 26 transverse folds are formed in the edge region, the Fold edges run in the direction of arrow 27. The edge area 26 can therefore be well adapted to undulating roof contours become.

In the figure there are longitudinal folds 28 to 30 of the edge region 26 shown. As with area 16, it could also be at further longitudinal folds 28 are formed in the edge region his. Both the area 16 and the edge area 26 are in such a case expandable like an accordion. The areas formed by the longitudinal folds 28 to 30 either be folded up so that the edge area 26 aligned as parallel as possible to the roof covering 20 or that the edge area 26 with a to the ridge tile 31 directed flow edge 32 is formed. The Flow edge 32 prevents that from the area of the roof covering 20 Snow or rain below the ridge tile 31 can penetrate to the air-permeable area 16.

The air-permeable area 16 consists of a large number individual filaments, which are connected to a grid. The Filaments consist of elastic threads made of plastic, so that the area 16 can be deformed in addition to to the area between ridge batten 15 and roof covering 20 to be adjusted.

One between the ridge tiles 31 and the ridge ventilation element 10 remaining free space 33 forms a flow or air ascent zone for those ascending from a roof interior Air and for those flowing across the ridge Air flow.

In this free space 33 that collects from the roof interior through the areas 16 exhaust air rising.

The airflow arriving on a windward side of the roof flows partially below the brick area 34 in the Free space 33 in. Below a brick area 35 can the air flow emerges from the free space 33 again and takes the exhaust air located in the free space 33. Other Parts of the air flow are directed over the ridge tile 31 and generate one on the leeward side in the brick area 35 Vacuum. Consequently, the one located in the free space 33 Air sucked out under the brick area 35, so that a good ventilation of the roof interior is guaranteed.

For ventilation of the roof interior, it is advantageous if the air flow in the free space 33 takes place in the direction of arrow 27.

Fig. 2 shows how the ridge ventilation element can be transported before it is installed.

The ridge ventilation element 10 consists of the middle part 11 and the side parts 12. The ridge ventilation element 10 built symmetrically to the middle section on one Ridge slat (see Fig. 1) to be attached. According to the invention are also conceivable ridge ventilation elements that are constructed asymmetrically or only for sealing and ventilation serve a single sloping roof.

The side parts 12 adjoin the middle part 11 on both sides on. Each side part 12 is in turn made of an air-permeable Area 16 and from a non-air permeable Area 26 together. The air-permeable area 16 is made from a large number of individual filaments that form one Network or grid are connected together. The grid is in 2 only hinted at.

The side parts 12 of the ridge ventilation element 10 have Longitudinal folds 18, 19 and 28 to 30, so that the side parts 12th can be compressed as evenly as possible. In the fortified Condition of the time ventilation element 10 can the side parts 12 can be expanded to different distances and gaps between the ridge and the roof covering bridged. In the figure, sections of the side parts 12 pressed flat so that the ridge ventilation element 10 can be rolled up into a roll. The ridge ventilation element 10 is made of an elastic plastic. Therefore, the side parts 12 can be easily folded up, pull apart and if necessary again again fold. The longitudinal folds 18, 19 and 28 to 30 can already in the finished state of the ridge ventilation element 10 can be formed, but they can also be due the deformability of the material by the craftsman on others Place the side parts 12 molded into the material become. Through the formation of the longitudinal folds 28 to 30 can in the edge area 26 a different size from the edge area 26 upstanding flow edge (see Fig. 1) formed be, the height of which on the free space below the ridge tile can be coordinated.

According to FIG. 3 , a ridge ventilation element 40 is composed of a central part 41 and adjoining side parts 42. The middle part 41 is flat and made of a material that differs from the material of the side parts 42. The side parts 42 are composed of two separate components, an air-permeable area 43 and a non-air-permeable edge area 44. The area 42 and the edge area 44 are made of different materials and glued together. The area 42 can therefore very well let air flows through, while the edge area 44 can perform a good sealing function.

The area 42 is pushed together like a bellows with upstanding longitudinal folds, around the extension of the ridge ventilation element 40 to be able to vary in the direction of arrow 45. The edge area 44 has transverse folds 46 for adaptation to wavy ones Roof coverings (see Figure 1). A flow edge 47 can prevent snow or rain from entering.

A ridge and / or ridge ventilation element 10 has a Middle part 11, which can be attached to a ridge or ridge batten 15 is, and a side part 12. Both sides adjoin the middle part 11 side parts 12 with their outer Edge areas 26 can be placed on roof coverings 20 and between its edge regions 26 and the central part 11 are permeable to air are trained. The side parts 12 are in their air-permeable area 16 and / or in its outer Edge areas 26 with in the longitudinal direction 17 of the ridge and / or Ridge ventilation element 15 longitudinal folds 18, 19, 28 to 30 provided. By using the ridge and / or Burr ventilation element 10 can have differently sized free spaces covered in such a way between ridge batten and roof covering be that between ridge and roof covering Air circulation is possible and the area between Ridge tiles and roof covering are easy to seal.
