Abstract

The side parts (3) abutting on the central part (2) are formed with air through passage areas (21) between their edge areas (21) and the central part. These areas are formed as spaced flow apertures in air permeable areas of the side parts. The flow apertures extend over at least one longitudinal fold (10-14) in the ventilating component (1) longitudinal direction. The flow apertures of the side parts are closed by an air-permeable material layer fixable to the under side or the upper side of the side part, in order to close several flow apertures.

Description

The present invention relates to a ridge 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 with air passage areas are formed as individual spaced apart Flow openings in the air-impermeable areas of the side parts are incorporated.

Such a ridge or ridge ventilation element is through the German utility model 295 01 242.0 became known.

Ridge 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 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 or ridge ventilation element adequate ventilation of the roof interior be made possible to prevent the roof truss from rotting To protect damage.

In the known ridge or ridge ventilation element comes into play Median strip over two longitudinal, between each beads having a section of a predetermined length into a hard shoulder. Because of this training the ridge or ridge ventilation element has preformed snap edges on which each to different ridge and / or Burr widths are customizable.

Problems now arise when the ridge ventilation element Gap between ridge batten and roof covering not as intended can cover up. In these cases, sealing problems arise in the border areas between roof covering and Ridge tiles on. There can also be ventilation problems from the improper fastening of the ridge ventilation element result, because the air-permeable area of the side part underneath Under certain circumstances on the ridge or on the roof covering comes to the plant. The air-permeable area can for this reason, the ventilation function of the Meet the interior of the roof.

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.

DE 40 01 766 C2 also discloses a ridge 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 or Ridge ventilation element unable to differentiate Cover the distances between the ridge batten and the roof covering can.

The present invention therefore has the technical problem to present a ridge or ridge ventilation element, by using different sized spaces covered in such a way between ridge batten and roof covering that can be between ridge and roof covering air circulation is possible and the area between Ridge tiles and roof covering easy to seal is.

According to the invention, this technical problem is solved by that the flow openings over at least one extending in the longitudinal direction of the ridge or ridge ventilation element Extend longitudinal fold of a side part, the one Material supply area creates, so that the ridge ventilation element is designed extendable in its lateral length.

By forming one or more longitudinal folds in the Side parts of the ridge ventilation element can be the ridge ventilation element variable to different distances between Ridge lath and roof covering react. The folds in Longitudinal direction of the ridge ventilation element ensure that the lateral extension of the ridge ventilation element accordingly can be adjusted. If the air passage areas can extend over the longitudinal folds despite wrinkling, an area necessary for ventilation of the side part remain. Vice versa even if the distance between the ridge is reduced and roofing new creases are created so that the ridge ventilation element is shortened laterally accordingly. For this reason, the edge area is always sealed the roof covering, while the air permeable area of the side part of the ridge ventilation element optimally aligned is fixed between the ridge.

Tolerance fluctuations through the use of different Ridge or ridge slats and their aligned fastening therefore have no 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 or ridge ventilation elements on top of each other towards the ridge tile are arranged 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 elements are the flow openings the side parts of an air-permeable material layer locked. In the manufacture of the ridge ventilation element can initially flow openings in the side panels incorporated with an appropriate tool (punched, cut or the like) and then be covered by the layer of material. The Integration of the air-permeable areas in an air-impermeable Side part can therefore be carried out easily become. In particular, the training: of air passage areas coordinate well with the formation of the longitudinal folds, so that functional ventilation is always guaranteed is.

Machine can simplify the manufacturing process of the ridge ventilation element, the material layer as a material web on the bottom or top to attach the side panel to multiple flow openings to close. The material web is in its dimensions matched to the side panel and can be the bottom of the Cover the side part including the flow openings.

Of course, the craftsman could also add flow openings later train with a suitable tool and seal with a layer of material.

The attachment of the material web is special in one variant easy to carry out with the material web on the underside or top of the side part can be stuck on is.

The material layer preferably consists of a fabric membrane. By using a fabric membrane it is possible to that optimal air permeability and moisture transport is possible from the inside out, but none Moisture penetrate into the roof from outside can.

The material layer can also be formed by individual filaments be made into a malleable lattice or fabric with each other are connected. By arranging the individual An area of the ridge ventilation element is created flow through the air with high efficiency can. Even if parts of the side parts with a Grid structure can be folded over each other anyway Flow air outwards from the interior of the roof. In contrast becomes the state of the art through the predetermined grid openings always a defined possibility for air flow guaranteed.

The material layer of the air passage area is preferred by threads made of an elastic plastic or metal built up. Such threads (filaments) can be used the air passage area of a side part in addition to Shapeability through the longitudinal folds according to the invention further deform or adapt to 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 a covering a tennis racket can counter the filaments are shifted to correct each other if necessary that the air permeability is impaired.

In a further preferred embodiment, this is Ridge or ridge ventilation element made of a flexible, deformable Rollable material. This has the advantage that the Ridge or ridge ventilation element rolled up into larger rolls that can be stored very easily and inexpensively, can be transported and fastened in the roof area. Rolls with a length of sufficient for an average roof. By rolling of the ridge ventilation element, the craftsman can easily the ridge ventilation element on the ridge batten and the Fasten 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 or the outer edge areas of the side part with a activatable adhesive layer are provided. By pulling it 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.

Fig. 1 shows a ridge ventilation element 1, such as it is arranged in the ridge area of a roof truss.

The ridge ventilation element 1 has a central part 2 and adjoining side parts 3. When the Ridge ventilation element 1 is the middle part 2 with his Middle part underside 4 on the top 5 of the staff Ridge slat 6 on. On the middle part underside 4 has that Middle part 2 an adhesive layer, so that the middle part 2 the ridge batten 6 is permanently and securely fixed.

The side parts 3 are essentially impermeable to air trained and include air passage areas 7. These Areas 7 can have any dimensions and outer contour. They allow air circulation so that air can be discharged from the roof interior 8 to the outside. In contrast, moisture cannot enter the interior of the roof 8 reach. In the side parts 3 there are two in the longitudinal direction 9 the longitudinal folds 10 of the ridge ventilation element 1 and 11 incorporated. Due to the formation of the longitudinal folds 10 and 11, the side part 3 can be transverse to the longitudinal direction 9 be unfolded. The extension of the ridge ventilation element 1 transverse to the longitudinal direction 9 can therefore be changed become. By forming even more longitudinal folds 12 to 14 this function can be enhanced. Leave it there are different distances between the ridge batten 6 and bridge a roof covering 15.

The roof covering 15 is made of individual roof covering plates formed and lies on roof battens 16 and 17. The Roof battens 16 and 17 are attached to rafters 18 and 19. The ridge 6 is above the rafters 18 and 19 arranged with the aid of a ridge slat holder 20.

A non-air-permeable edge area 21 serves for sealing between a ridge tile 22 and the roof covering 15. The side parts 3 sit out of the air passage area 7 and the non-air-permeable remaining area together. The edge region 21 can also be folded up, so that its length in the direction of arrow 23 can also be varied can. In addition, 21 transverse folds are formed in the edge area, whose fold edges run in the direction of arrow 23. The edge region 21 can therefore be well on wavy roof contours be adjusted.

The side parts 3 are expandable like an accordion. The areas formed by the longitudinal folds 12 to 14 either be folded up so that the edge area 21 aligned as parallel as possible to the roof covering 20 or that the edge area 21 with a to the ridge tile 22 aligned flow edge (longitudinal fold 13) is. The flow edge prevents it from leaving the area the roof covering 15 snow or rain below the Ridge tile 22 penetrate to the air passage areas 7 can.

The air passage areas 7 consist of a material layer covered flow openings of the side parts 3. The layer of material comprises individual filaments that form one Grids or fabrics are connected. The filaments exist made of elastic threads made of plastic, so that the air passage area 7 can be deformed additionally, to the area between ridge batten 6 and roof covering 15 to be adjusted.

One between the ridge tiles 22 and the ridge ventilation element 1 remaining free space 25 forms a flow or Air ascent zone for the ascending from the roof area 8 Air and for those flowing across the ridge Air flow.

The space 25 collects from the roof interior 8 exhaust air rising through the air passage areas 7.

The airflow arriving on a windward side of the roof flows partially below the brick area 26 in the Free space 25 in. Below a brick area 27 can the air flow exits the free space 25 again and takes thereby the exhaust air located in the free space 25. Other Parts of the air flow are directed over the ridge tile 22 and generate one on the leeward side in the brick area 27 Vacuum. As a result, that located in the free space 25 Air sucked out under the brick area 27, so that a good ventilation of the roof interior 8 is guaranteed.

For the ventilation of the inner roof area 8, it is advantageous when the air flow in the free space 25 in the direction of the arrow 23 takes place.

Fig. 2 shows how the ridge ventilation element before its assembly can be transported.

The ridge ventilation element 1 consists of the middle part 2 and the side parts 3. The ridge ventilation element 1 built symmetrically to the middle part 2 on a Ridge slat 6 (see Fig. 1) to be attached. According to the invention ridge ventilation elements 1 are also conceivable, which are asymmetrical or only for sealing and Ventilate a single roof slope.

The side parts 3 adjoin the middle part 2 on both sides. Each side part 2 is in turn composed of air passage areas 7 and non-air-permeable areas 28 together. The air passage area 7 consists of a large number individual filaments that form a network or grid are connected. The grid is only indicated in FIG. 2.

The side parts 3 of the ridge ventilation element 1 have Longitudinal folds 10 to 14, so that the side parts 3 if possible can just be squeezed together. When attached of the time ventilation element 1, the side parts 3 can be expanded to different distances and gaps to bridge between ridge and roof covering. In the figure, sections of the side parts 3 are pressed flat together, so that the ridge ventilation element 1 to a role can be rolled up. The ridge ventilation element 1 is made of an elastic plastic. Therefore leave the side parts 3 fold up slightly, pull apart and fold up again if necessary. The longitudinal folds 11 to 14 can already in the finished state of the ridge ventilation element 1, they can also due to the deformability of the material by the craftsman elsewhere in the side panels 3 in the material can be molded. By training the Longitudinal folds 11 to 14 can be different in the edge region 21 large flow edge rising from the edge region 21 (see Fig. 1) are formed, the height of which the space below the ridge tile can be coordinated can.

In the side part 3, as can be seen in Fig. 3, are Flow openings 29 incorporated through an air-permeable Material layer 30 are closed. The flow openings 29 form together with the material layer 30 Air passage areas 7. The material layer 30 is on the Underside of the side part 3 firmly by an adhesive connection appropriate. The material layer 30 can be glued continuously be and cover several flow openings.

A ridge ventilation element 31 is seated again according to FIG. 4 from a middle part 32 and adjoining side parts 33 together. The middle part 32 is flat. and Made from a material that differs from the material the side parts 33 differs. Set the side parts 33 consist of two separate components 34 and 35. Component 34 and component 35 are different Made of materials and glued together. In the Part of air passage areas 35 are incorporated, the air passage areas 7 according to FIGS. 1 and 2 correspond. Therefore, air flows through the component 35 penetrate very well, while the component 34 a can perform a good sealing function.

The component 35 is bellows-like with upstanding longitudinal folds pushed together to extend the ridge ventilation element 30 to be able to vary in the direction of arrow 36. The part 34 has transverse folds to adapt to wavy ones Roof coverings (see Figure 1). A flow edge 37 can prevent snow or rain from entering.

A ridge or ridge ventilation element 1 comprises a central part 2, which can be attached to a ridge or ridge slat 6 is, and on both sides of the middle part 2 adjacent side parts 3, with their outer edge areas 21 on roof coverings 15 can be placed and between their edge regions 21 and the middle part 2 are formed with air passage areas are. The air passage areas 7 are single, spaced-apart flow openings in air-impermeable Areas of the side parts 3 7 incorporated, where the flow openings over at least one in the longitudinal direction 9 of the ridge or ridge ventilation element 1 extending Longitudinal fold 10 to 14 of a side part 3 extend. By using the ridge or ridge ventilation element 1 there can be different sized spaces between the ridge 6 and roof covering 15 are covered such that between Ridge lath 6 and roof covering 15 an air circulation is possible and the area between ridge tiles 22 and Roof covering 15 is easy to seal.
