Description

The present invention relates to a windbreak pad for use in windproofing a pitched roof structure of a building having a window frame installed therein. The invention further relates to a kit comprising a plurality of wind protection pads and a sealing collar for use in the installation of a window frame, the roof structure comprising rafters, a flexible sub-roof and roof battens adapted to support a roofing material.

During the installation of a window in a pitched roof that includes a sub-roof, an opening for the window frame is created by removing roofing material and cutting through the battens and sub-roof, thereby breaking the water and wind protection.

In order to make the transition between the installed window frame and the sub-roof watertight and to prevent the seepage of water into the roof structure, a sealing collar, also known as a sub-roof collar, is commonly used. Such an under roof seal is out of the EP0994992B1 known. The under-roof seal is installed after the window frame and possibly an insulation frame have been installed in the opening. During installation, the under-roof seal is pulled over the window frame and attached to the outside of the window frame, ie the side facing away from the frame opening. To fulfill its purpose, the sub-roof collar must be in close engagement with both the outside of the window frame and the sub-roof of the roof structure next to the window. Careful installation of the under-roof seal is thus required, which means that the process is prone to errors caused by incorrect handling and time constraints.

The provision of a sub-roof collar also provides a certain wind protection, but to further improve the insulation at the transition between the window frame and the roof structure, the roof opening is often designed somewhat oversized and an insulation frame is arranged in the opening between the window frame and the roof structure. Such an insulation frame is, for example, from EP2677092B1 known, but again incorrect handling and time constraints can result in the isolation frame not coming into close engagement with the window frame and / or roof structure, resulting in inadequate isolation.

Another approach to securing the roof opening from wind is from the EP1518974A1 known. Here, areas of the sub-roof material that previously covered the roof opening are folded over the roof battens at the top and bottom of the roof opening and metal rails are arranged along the sides of the roof opening so that they clear the gaps between the ends of the roof battens that were created when the roof opening was made have been breached, cover. Curved areas at the ends of the rails superimpose the folded-down sub-roof areas on the top and bottom, so that a continuous windbreak is formed that extends completely along the inside of the roof opening. An additional windbreak tape is used along the sides of the roof opening to secure the windbreak structure. However, this method has the disadvantage that the rails are relatively expensive to manufacture and that the metal used for the rails forms thermal bridges, which leads to a reduction in the thermal insulation properties of the final structure.

Thus, it is an object of the invention to provide a means for use in windproofing a pitched roof structure of a building with a window frame installed therein which is relatively inexpensive, does not adversely affect the thermal properties of the structure and has a low risk of errors during installation . Another object of the invention is to provide a method of installing a window frame in a pitched roof structure that is relatively inexpensive, does not adversely affect the thermal properties of the structure, provides wind protection and has a low risk of errors during installation.

• einen ersten Bereich, der dazu konfiguriert ist, sich entlang der ersten Innenseite der Dachöffnung zu erstrecken, und
• einen zweiten Bereich, der dazu konfiguriert ist, sich entlang der zweiten Innenseite der Dachöffnung zu erstrecken, wobei
• der erste und der zweite Bereich entlang einer Verbindungslinie miteinander verbunden sind.

The first object is achieved with a wind protection pad for wind protection of an inner corner of a roof opening in a pitched roof structure of a building, where a first and a second inner side of the roof structure which delimit the roof opening meet, the wind protection pad comprising:

• a first area configured to extend along the first interior side of the roof opening, and
• a second region configured to extend along the second interior side of the roof opening, wherein
• the first and the second area are connected to one another along a connecting line.

The windbreak pad can be attached to a corner of a window mounting frame for use in installing a window frame in a pitched roof structure of a building where a inner side of the fastening frame facing the inside of the building and an outer side facing the outside of the building, and an inside facing an opening delimited by the fastening frame, can be used, the first area of the cushion being configured to the outer side, the inner Side and inside of a first member of the mounting frame at least partially, and the second area is configured to at least partially cover the outside, the inside and the inside of a second member of the mounting frame.

Here, a mounting frame can be an installation frame as described below with regard to other aspects of the invention, or it can be an insulation frame arranged in a roof opening, or it can be part of the roof structure that delimits an opening for the window, for example auxiliary roof battens that around the window opening are arranged in the roof surface to assist in supporting the window frame.

Since the first and second areas are connected to one another along a connecting line, the first and second areas can extend in a fastened state along two inner sides which extend orthogonally to one another, i. H. on a corner. The first and second areas can be made from separate pieces of material which are attached to the connecting line by a connecting means, such as e.g. B. an adhesive, glue, tape, welds or welds, can be connected to one another. In one embodiment, a strip is adhered to the first and second areas to connect them together, thereby providing a particularly flexible connection along the connecting line. The material that forms the first area can thus be spaced from the material that forms the second area, and the gap can be covered by the strip. The strip can be made of the same material as either or both of the pads, or can be made of a different material. The manufacture of the strip from an elastic material allows a high degree of flexibility during the attachment of the pad. Alternatively, the first and second areas can be made from a single piece of material with a connecting line.

In a delivery state, the cushion can be folded over at the connecting line, so that the first and the second area lie in parallel planes, which enables easy and compact storage. In addition, the connecting line is preferably preformed in the material of the first and / or the second area and / or of the connecting means. The connecting line can be produced, for example, by deforming, hitting or weakening material along the bending line or by applying a strip, an adhesive or the like.

The cushions can be fixed by fixing means, such as. B. an adhesive, to ensure a wind-tight and reliable connection to the first and the second inner side or the first and the second member of the fastening frame can be fixed. Accordingly, an adhesive may be provided on a back side of the pad which, in use, faces the inside or the mounting frame. Preferably the adhesive is applied to the entire area of both the first and second areas. Alternatively, the adhesive may be applied to part of the surface of the first and / or second area, e.g. Along the edges of the area (s). The adhesive is preferably applied during production and thus a removable cover, such as e.g. B. paper, cardboard, foil, film or the like, which prevents the sticking and / or hardening of the adhesive during storage and transport, can be provided on the adhesive. The cover can be provided in one piece and cover the entire adhesive surface of both the first and second areas. Preferably, the cover comprises some pieces of material which can be individually removed to allow easier installation of the pad, since the entire surface of the adhesive is not necessarily exposed at once.

• einen ersten oberen Bereich und einen ersten Seitenbereich, der entlang einer Biegelinie mit dem ersten oberen Bereich verbunden ist;
• und der zweite Bereich umfasst:
  • einen zweiten oberen Bereich und einen zweiten Seitenbereich, der entlang der Biegelinie mit dem zweiten oberen Bereich verbunden ist.

In one embodiment of the windbreak pad, the first area comprises:

• a first upper region and a first side region connected to the first upper region along a bend line;
• and the second area includes:
  • a second upper area and a second side area which is connected to the second upper area along the bending line.

Preferably, the first upper region is configured to be applied to an outer side of a roof structure along the first inner side or a first member of a mounting frame, and the first side region is configured to at least partially an inner side of a roof structure or the first member of the mounting frame to cover. Likewise, the second upper region is preferably configured to be applied to an outer side of a roof structure along the second inner side or a second member of the mounting frame, and the second side region is preferably configured to at least partially an inner side of a roof structure or the second member to cover the mounting frame.

Since the respective side areas and upper areas are connected to one another along a bending line, the cushion can be folded into a position that resembles its intended shape in the attached state, with the upper areas extending in the folded state in a plane that corresponds to the The plane of the side regions is substantially orthogonal. Accordingly, since the pad can be folded into the intended shape, ie, the shape of a mounting frame corner, the pad can be self-positioning. Similar to the connecting line, the bending line is preferably preformed. The preforming can be carried out in a manner similar to that explained for the connecting line.

In a further embodiment of the wind protection pad, one end of the first and second upper regions, the end that extends along the connecting line, preferably at an angle of approximately 45 degrees, to a length direction that is parallel to the inside of the roof opening and to the plane of the Badger runs in the fastened state, angled. As a rule, this means that the ends of the upper regions are angled at an angle of approximately 45 ° to a corresponding end of the first and the second side region, which extends along the connecting line.

Since one end of each of the first and second upper areas is angled, the ends of the upper areas adjoin one another along the connecting line when folded down, so that they together form an L-shaped upper area that is designed to be parallel to the To extend level of the roof structure, while the side areas extend into the roof opening. This in turn allows wind protection along the entire connecting line and further assists the wind protection pad in maintaining a shape that is substantially similar to its intended shape in an attached state.

This in turn allows easy installation of the windbreak pad.

In yet another embodiment, the windbreak pad further comprises at least one strut to provide additional rigidity to at least part of the first and / or the second area.

The strut, which provides additional rigidity, assists the windbreak pad in maintaining the intended shape in an attached condition when the windbreak pad is in its folded-over condition, thereby enabling easy installation. A strut is preferably provided on each upper region of the pad. If either or both of the upper portions include a brace, the braces help the upper pieces to lie correctly on the outside of the mounting frame or roof structure, thereby reducing the risk of inadvertent bending, folding or creasing, thereby allowing easy installation of the cushion .

The strut can extend along the entire length and / or width of the upper region, or it can extend along part of the length and / or width thereof. The strut can be made of a hard plastic material, such as. B. polymethyl methacrylate (PMMA), polyvinyl chloride (PVC), polyethylene (PE), such as. B. a high-density polyethylene (HDPE), or the like, made of cardboard, by applying a stiffening substance, such as. B. a cured adhesive, on the material of the pad, from a wire embedded in the material, etc., be made.

• einen ersten unteren Bereich, der dazu konfiguriert ist,
• zumindest zum Teil eine innere Seite einer Dachstruktur entlang der ersten Innenseite oder des ersten Glieds des Befestigungsrahmens zu bedecken;
• und der zweite Bereich umfasst ferner:
  • einen zweiten unteren Bereich, der dazu konfiguriert ist, zumindest zum Teil eine innere Seite einer Dachstruktur entlang der zweiten Innenseite oder des zweiten Glieds des Befestigungsrahmens zu bedecken.

In a further embodiment of the wind protection pad, the first area further comprises:

• a first lower area configured to
• at least partially covering an inner side of a roof structure along the first inner side or first member of the mounting frame;
• and the second area further comprises:
  • a second lower region configured to at least partially cover an inner side of a roof structure along the second inner side or the second member of the mounting frame.

The respective lower portions can then be bent into position, i.e. H. around the respective link of the mounting frame or under an inner side of the roof structure. This in turn allows easy attachment, particularly when the pad is adhered to the attachment frame. Alternatively, the respective lower areas can be connected to one another at the respective side areas without attachment to the roof structure or the mounting frame by a second bending line, which allows the cushion to be folded into its intended shape. The second bending line can be preformed in the same way as the first bending line and / or the connecting line.

The first and second lower areas can be connected along the connecting line to form a preferably windproof connection along the connecting line when they are attached. Thus, one end of each of the lower areas can go to the end of the side areas where the ends of these areas meet the connecting line wise to be angled. The angle can be 45 degrees or less to accommodate varying dimensions of the mounting frame or roof structure.

Alternatively, in an attached state, the first and second lower portions may not be connected along the connecting line to further accommodate larger widths of the attachment frame members or the roof structure. Accordingly, the ends of the lower regions need not be angled towards the end of the side regions.

The wind protection pad according to the invention can be used in combination with or independently of any of the other aspects of the invention. The wind protection cushion can thus be used without a sealing cuff and / or an installation frame.

The second object is achieved with a method that comprises the following steps:

1. A) Creating a rectangular roof opening in the roof structure, whereby an inside of the roof structure, which faces the roof opening, is created, and wherein the part of the sub-roof that previously covered the roof opening is divided into four sub-roof areas, each of which extends along one Side of the roof opening extend,
2. B) providing a sealing collar comprising an installation frame comprising upper, lower and side members which meet at four corners and together define an inner edge defining a collar opening at least when the installation frame is in the attached state, the Sleeve opening is designed to surround the window frame,
3. C) arranging the sealing collar on the outer side of the roof structure so that the collar opening is essentially aligned with the roof opening when viewed in a direction perpendicular to the plane of the roof structure,
4. D) attaching the installation frame to the roof battens,
5. E) Folding up the sub-roof areas along the inside of the roof structure and attaching this to an outer side of the installation frame,
6. F) applying at least one wind protection cushion to each corner of the sealing collar, so that two sub-roof areas are connected to the installation frame and / or with one another and so that a continuous wind protection is provided that extends along the entire inner edge, and
7. G) Inserting the window frame into the cuff and roof opening.

By providing a sealing collar with an installation frame on the outer side of the roof battens, dividing the part of the sub-roof that previously covered the roof opening into four sub-roof areas and attaching these to the outer side of the upper, lower and side members of the installation frame, respectively Wind protection created with minimal use of new materials, d. H. there is no need to apply additional windbreak tape along the entire circumference of the cuff opening.

In addition, the fact that the windbreak will become an integral part of the existing sub-roof means that the number of connection points and thus the number of possible leaks is low.

The installation frame is preferably plate-shaped, so that in a fastened state it extends in a plane running parallel to the plane of the roof surface. The installation frame only needs to have a rigidity sufficient to span the gaps between the roof battens without great sag and be suitable for supporting the four sub-roof areas. As a result, the amount of material required is small and manufacture can be made from relatively inexpensive materials such as e.g. B. polymer layer, such as. B. a layer of polyethylene (PE), polypropylene (PP), polyurethane (PU), polymethyl methacrylate (PMMA) or polycarbonate (PC), a corrugated plastic sheet or a material based on natural fibers, such as cardboard, plywood, chipboard or fiberboard, or made of composites with one or more of these materials. The layers could, for example, be solid, hollow, with channels, corrugated, with a honeycomb structure or combinations of these. The material should allow the installation frame, in a fastened state, to be dimensionally stable in a plane running parallel to the plane of the roof surface, i.e. H. such that the cuff opening retains its dimensions.

When installing a roof window on the installation frame, there are fastening brackets for the roof window, which are intended to rest on roof battens, on the installation frame. This can cause the window to be positioned higher than intended with respect to the roof surface. Thus, the material of the installation frame preferably allows a certain deformation in the Height direction, ie when viewed from an inner to an outer side, of the installation frame when installing a roof window. This can be achieved, for example, in that the installation frame comprises channels in a longitudinal direction of one or more of the side members which, in an attached state, allow local compression of the installation frame under the fastening brackets due to the weight of a roof window attached thereto. As an alternative to this or in combination therewith, the installation frame can comprise weakened sections, ie sections which comprise less material, for receiving fastening brackets of a window. In yet another embodiment, areas of the installation frame in which the mounting brackets are to rest are compressed in advance or made of a thinner material than the rest of the installation frame. The installation frame can comprise several such receiving areas, which are designed for different installation situations in which the fastening brackets are attached to the window frame at different positions.

The installation frame can be a one-piece monolithic structure, e.g. B. made of one piece of material, or can be made of several pieces that are connected to each other to form the installation frame. The installation frame is preferably made of a material with a thickness of less than 10 mm, measured in a fastened state from an inner side to an outer side, and preferably about 1-4 mm. The thickness of the installation frame material can depend on the area of the roof opening and / or sleeve opening. The thickness of the installation frame can be, for. B. be defined as 1 mm per square meter of area, measured in the plane of the roof surface, the roof opening. The thickness of the material of the installation frame can furthermore depend on the type of material used.

Since the sub-roof areas often cannot cover the entire inner surface of the roof opening, the cushions are used to connect them either directly or by connecting each to the installation frame and / or to members of the roof structure. In a currently preferred embodiment, a cushion connects two sub-roof areas with one another and connects these two to the installation frame.

The cushions can be of many different constructions, but it is currently preferred to use adhesive cushions made of a material similar to that used for the sub-roof and with the side provided with the adhesive with a cover sheet as shipped can be provided. The cover layer and / or the cushion itself can be provided with instructions for use.

Such cushions can also be used without the sealing collar which connects the sub-roof areas with one another and with the roof structure, e.g. B. be attached to roof battens or the like. The pads can be used alternatively or in combination with other connection points, such as e.g. B. corner junctions, junctions between different elements, e.g. B. roof battens, insulation material, borders, covers or the like to solidify.

The attachment of the cushions is simplified if one or more tabs on the inner edge of the installation frame are folded down so that they protrude from the plane of the cuff down into the roof opening and so that they line the inner surface at least at the corners. If the installation frame is made of a material that is inherently windproof, and if a gap between the sub-roof areas is completely spanned by these flaps, the cushions need not be windproof. However, it is currently preferred to use windbreak pads.

When fastened, tabs protruding from the installation frame and down into the roof opening can also be used to position the sealing collar with respect to the roof opening and / or to check that the roof opening has the intended dimensions. If tabs are provided on two opposite sides of the cuff opening and protrude from the inner edge, they should both engage the inner surface of the roof opening when the roof opening is of the correct dimensions and the sealing cuff is properly positioned. This applies regardless of the use of upholstery.

The installation frame can also be used to carry insulating members which are designed to form an insulating frame when fastened. In one embodiment, the method thus further comprises the step H) of moving insulation members, which are part of the sealing sleeve and which are attached to the installation frame, from a first position in which they are arranged on an outer edge of the installation frame opposite the inner edge a second position in which they protrude into the roof opening and line at least part of the inside. Step H) is preferably carried out before step G), since this is considered to be the least error-prone, but it is also possible to remove the insulating members after the Insert window frame in a space between the window frame and the inner surface.

Such integrated insulation members can be connected to the installation frame by a connecting material having a width which essentially corresponds to the width of the installation frame. One side of the connecting material is preferably attached to the outer edge of the installation frame and the other side is attached to the insulation member at the level that is to be positioned on the inner edge of the installation frame in the fastened state. In this way, the connecting material ensures that the insulating member cannot be inserted too far into the roof opening, and the connection between the connecting material and the insulating member can serve as a hinge, thereby allowing the insulating member to be pivoted into the correct fastening position, by rotating it around the inside edge of the installation frame.

Isolation links need not be on all four sides of the sealing sleeve, and the isolation links will often be of different constructions. In one embodiment, at least one insulating member is provided with an interruption or weakening, which allows a part of the insulating member to be moved between an installation position and a fixed position to make room for other parts of the sealing sleeve, for tools used during installation or for parts of the window frame. It is currently contemplated to provide such breaks to make room for mounting brackets of the window frame so that they can come into direct contact with the installation frame and so that insulation material can be placed over the mounting brackets after they are attached to the roof structure have been.

If the connecting material is a strip of sheet material that corresponds to or is similar to the material used for the sub-roof, it will also provide additional wind protection by overlaying the sub-roof areas attached to the outer side of the installation frame. In such cases, the method can advantageously include the step I) arranging secondary windbreak pads at the corners of the installation frame, step I) being carried out after step H) and preferably before step G). These secondary pads can be used to connect the connecting material associated with each insulating member and / or to connect the connecting material to the outer side of the installation frame.

It is noted that if the sealing collar does not comprise any insulating members, the roof opening can be provided with a separate insulating frame, for example from FIG EP2677092B1 is known. If such an insulation frame is attached before the sub-roof areas are attached to the outer side of the installation frame, the inside of the insulation frame forms the inside of the roof opening.

It is also noted that insulation material can be arranged in the spaces formed between the roof battens, the sub-roof and the installation frame. Such insulation material can be arranged between the roof battens before the sealing collar is fastened, provided on the inner side of the installation frame or introduced into the inside of the roof opening through openings between roof battens.

When the window frame has been secured in the roof opening, it is usually attached to the roof structure to hold it in the intended position. This can be done by J) attaching the window frame to the roof structure by passing fastening means through the installation frame, the fastening means preferably being screws which pass through openings in fastening brackets attached to the window frame. In this way, the sealing collar is also secured to the roof structure. At the same time, the window frame and the sealing collar are fixed with respect to one another, which can be relevant, for example, if the installation frame is made with a collar opening that is larger than the outer dimensions of the window frame, and / or if it is made of a low-friction material.

To provide additional wind protection and water impermeability, the method can further include the step K) of arranging a sub-roof sleeve made of a waterproof membrane on the sealing sleeve, attaching an inner edge of the sub-roof sleeve to the window frame and attaching an outer edge of the sub-roof sleeve on the outer side of the roof structure, the sub-roof sleeve may be attached to the installation frame in the delivery state. Such under-roof seals are known to the person skilled in the art, but they were previously supplied and fastened separately.

In one embodiment, the sub-roof seal is attached in a rolled-up state to the outer edge of the upper member of the installation frame so that it can rest on the roof structure above the roof opening until it can should be installed without getting in the way of other installation steps.

The invention has been described above with reference to a method in which the roof opening is produced before the under roof seal is attached, but step A) can also be carried out after steps B) and C). In such cases, and if at least the inner edge of the installation frame is made of a substantially dimensionally stable material, the inner edge can be used as a guide for a cutting tool or as a drawing aid for transferring a guide pattern, which shows the intended position of the roof opening, to the roof structure .

According to a further aspect of the invention, the object is achieved by a kit comprising a plurality of wind protection cushions, which are designed for attachment to the sealing collar and to one or more sub-roof areas, and a sealing collar for use in the installation of a window frame in a pitched roof structure of a building wherein the roof structure comprises rafters, a sub-roof and battens adapted to support a roofing material, an inner side of the roof structure facing the interior of the building and an outer side facing the exterior of the building, with a rectangular roof opening in the roof structure and wherein the part of the sub-roof which previously covered the roof opening was divided into four sub-roof areas, each extending along one side of the roof opening, the sealing collar being designed to surround the window frame; wherein the sealing collar comprises an installation frame comprising upper, lower and side members that meet at four corners and together define an inner edge defining a collar opening at least when the installation frame is in the attached state; wherein the sealing cuff has an outer side which is designed to face the outside of the building in the fastened state, and an inner side which is designed to be arranged on the outer side of the roof structure, so that the cuff opening when viewed in FIG a plane running perpendicular to the plane of the roof structure is substantially aligned with the roof opening; wherein the installation frame is designed for attachment to the outer side of the roof battens; wherein the installation frame is designed for attaching the sub-roof areas on the outer side of the installation frame; and wherein the sealing cuff is adapted to attach at least one cushion to each corner, so that a continuous wind lock that extends along the entire inner edge is provided.

Embodiments and advantages described above in relation to one aspect of the invention also apply to the other aspects of the invention, unless stated otherwise.

The battens are designed to support a roofing material (not shown) that forms an outer surface of the finished roof structure that faces the exterior of the building.

In this case, the roof opening was rectangular 50 in the roof structure 5 before placing the sealing sleeve 1 on the outer surface of the battens 53 made, but it is also possible to make a preliminary hole, the sealing collar 1 and then use the installation frame as a cutting guide or drawing aid that determines the dimensions of the roof opening. The installation frame can advantageously be attached to the roof battens and / or additional roof battens before the roof opening is completed, and / or the installation frame can have one or more stabilizing members that prevent deformation of the cuff opening, with a stabilizing member being arranged in the cuff opening, for example .

The formation of the roof opening 50 means that an inside of the roof structure facing the roof opening is formed, the inside 55 at least through the end faces of those roof battens 53 that were interrupted to create the roof opening is defined.

As the roof opening 50 was made, became the part of the sub-roof 51 that previously covered the roof opening into four sub-roof areas 56 , each extending along one side of the roof opening, divided. Only two of these sub-roof areas, which extend along the upper side and the right-hand side of the roof opening, are in 1 however, it should be understood that similar areas extend along the lower side and the left side. In this case, the sub-roof has been cut along lines extending from each corner of the roof opening at an angle of approximately 45 degrees to the two sides that meet at that corner, and a central portion of the part of the sub-roof that previously formed the Roof opening has been removed. The remaining sub-roof areas 56 thus have a trapezoidal shape, as in 2 you can see. However, other shapes are also possible.

The installation frame 2 includes a top element 21 , a lower element 22nd and two side elements 23 , 24 that meet at four corners and together form an inner edge 25th define that delimits a cuff opening. In this case the installation frame is monolithic, made from a single piece of material, but it can also be composed of several pieces of material, for example to allow the sealing sleeve to be delivered in a folded-down state. The installation frame can then be assembled when it is placed on the outer surface of the roof structure.

In this embodiment the side members are 23 , 24 of the installation frame are provided with weakenings (not shown) extending in their lengthwise direction, thereby allowing an area 26th each side link into the roof opening 50 is folded down so that it is part of the inside 55 line the roof opening, as well as in 2 you can see. The connection points between these areas and the rest of the installation frame thus define the inner edge 25th of the sealing collar, and the distance between the connection points defines the width of the sealing collar. In this embodiment, the folded-down areas extend 26th along the entire length of the side links 23 , 24 , however, it is also possible to use smaller local flaps, which can be positioned at a corner, for example, in order to simplify their use for aligning the sealing sleeve with the roof opening.

After positioning in relation to the roof opening 50 becomes the sealing sleeve 1 regarding the roof structure 5 by attaching the installation frame 2 fixed to the roof structure. In this case, the installation frame was made using brackets 6th on the outer sides of additional roof battens 54 on the top and bottom and on the outer sides of roof battens 53 attached along the sides. However, it is also possible to use the flap sections 26th to be attached to the roof battens on the inside of the roof opening.

Referring now to FIG 3 can be seen how the sub-roof areas 56 over the inside 55 and on the outer side of the installation frame 2 where they were opened by means of brackets 6th were attached.

4th shows an adhesive wind protection pad 7th that is used to cover the parts at the corner that are not covered by the sub-roof areas 56 in 3 be covered, is thought.

5 shows how the upholstery 7th attached, and 6th shows the upholstery in the attached State. As can be seen, the notches allow 71 in the middle of the pad, which can be supplemented by an embossed line or weakening (not shown) extending between them to simplify the bending, that a pad can be 7th both on the inside 55 and the outer side on both the lower limb 22nd as well as on the side link 23 extends. This provides a continuous connection between the two sub-roof areas 56 and the installation frame 2 so that if upholstery 7th a continuous windbreak that extends along the entire inner edge has been attached to all four corners 25th extends, is provided.

In 7th are the isolation links 32 , 33 from its first position, which is shown in the previous figures, to a second position, in which it is in the roof opening 50 protrude and at least part of the inside 55 undress, has been moved. As can be seen, the connecting material has 35 that is the isolation links 32 , 33 with the installation frame 2 connects, a width W which is substantially the same as the width of the installation frame, and is on one side with the outer edge 27 of the installation frame connected, so that the connecting material 35 lies flat over the outer surface of the installation frame. In addition to providing further wind protection, this means that the isolation links 31 , 32 , 33 , 34 not too deep into the roof opening 50 can be introduced, neither during the attachment of the insulation member nor during the subsequent attachment of the window frame.

8th shows how the pieces of connecting material 35 that the side or lower insulating member 32 , 33 are assigned, with each other and with the installation frame 2 through a secondary adhesive wind protection pad 8th get connected. In this way, a wind lock is created not only on the inside and the inside, but also on the outside of the installation frame 2 generated. The secondary cushion 8th should preferably extend over the entire width W of the installation frame so that wind cannot penetrate under the connecting material at any point. In the embodiment shown, the installation frame members all have the same width W, but this is not required.

The upholstery 7th , 8th are described herein as being self-adhesive, but it should be understood that other types of pads could be used, that they could be other sizes and shapes than shown, and that more pads could be overlaid.

Ultimately, it becomes the window frame 9 attached by putting in the roof openings 50 and is thus also inserted into the cuff opening, as in 9 will be shown. As can be seen, there are mounting brackets 91 for attaching the window frame to the roof structure 5 on the outer side of the installation frame 2 either directly or with the connecting material 35 the isolating links in between. When screws (not shown) are then inserted into the holes in the mounting brackets, they penetrate the installation frame, thereby creating the sealing collar 1 on the roof structure 5 is fixed.

To space for the mounting brackets 91 to create and at the same time an insulation of the parts of the window frame 9 that are above the level of the outer side of the battens 53 extend, provide, are parts 36 , 37 of the insulating upper and lower limb 31 , 32 have been placed in an installation position and are designed to be moved to a fixed position once the window frame has been secured.

10 shows how an upper part 36 of the upper isolation link 31 has been cut off from the rest of the insulation link at the level of the outer side of the installation frame and how this cut off part 36 is held in a raised position. As can be seen, the upper part was made 36 also in a main part 361 and a holder part 362 divided. The cut separating these two parts is oblique, so that the holder part 362 on the side that runs from the cuff opening 10 is longer than on the side facing the opening. By pressing the main part 361 away from the cuff opening, past the one thus from the holder part 362 formed projection, the main part comes to rest on the outer side surface of the holder part. Once the mounting bracket (in 10 not shown) on the additional roof batten 54 has been secured, becomes the main part 361 back over the holder part 361 pressed so that it engages the outside of the window frame (in 10 Not shown). An adhesive can be used to seal the main part 361 to keep in engagement with the window frame or the mounting bracket, but since that of the holder part 362 The protrusion formed now prevents the main part from moving outwards, it is often not necessary.

The embodiment in 10 requires that the isolation member be made of a resilient and relatively soft material. Another embodiment, which is also suitable for non-elastic materials, is in the 9 and 11 shown. Here became an upper part 37 of the lower isolation link 32 completely separated from the remainder of the isolation link and by means of a length of tape 39 on an adjacent upper part 38 appropriate. The ribbon 39 serves as a hinge that allows the upper part to be separated 37 according to the Representation by the arrow between an installation position (in 9 seen), in which it extends along the outside of the adjacent upper part 38 extends, and a fixed position (not shown) in which it extends in continuation of the adjacent upper part 38 along the outside of the window frame (in 11 not shown) and extends over the outer side of the mounting bracket, can be pivoted. Once in the fastened position, the separated upper part 37 preferably attached to the outside of the window frame or to the mounting bracket. A temporary attachment of the separated upper part 37 in the installation position can also be beneficial.

This embodiment can be used on all sides of the sealing sleeve 1 and can be used with almost all types of insulation materials and all types of window frames.

Of course, other embodiments of the insulation members are also possible, and it goes without saying that the invention is not limited to methods in which insulation members protrude beyond the outer side of the roof battens in the fastened state.

Another embodiment of a wind protection pad 7 ' is in 12th shown. It includes a first area 72 with a first upper area 720 , a first page area 722 that of the first upper area 720 is separated by a bending line B, and a first lower area 724 . The first area 72 is with a second area 74 connected with a similar construction along a connecting line A. The connecting line A allows the corner pad 7 ' in the in 13th The shape shown in FIG 5 shown upholstery 7th can follow.

Likewise, the respective upper areas 720 , 740 , Side areas 722 , 742 and lower areas 724 , 744 from individual pieces of material, which by a connecting means, such as. B. an adhesive, welds, welds or the like, are connected to each other, be made. The connecting and bending line (s) can be formed and / or preformed by such connecting means.

In this embodiment, the first 72 and the second area 74 through a strip 76 , which extends along the connecting line A, connected to each other. The stripe 76 is made of a material similar to that of the first 72 and the second area 74 is shaped and is preformed to form the connecting line A in the strip, thereby creating the cushion 7 ' easily in the state in 13th and 14th can be brought. The stripe 76 will be at first 72 and the second area 74 glued, but can alternatively be attached to the first 72 and / or second area 74 welded, connected to it by a weld seam or the like.

As in 12-14 is shown, the first comprises the upper portion 720 a first strut 726 and the second upper area 740 includes a second strut 746 . The striving 726 , 746 are attached to the pad during manufacture 7 ' adhered, but can alternatively be welded to it or connected by a weld seam, integrated into the material of the upholstery or in situ on the upholstery 7 ' be liable. The striving 726 , 746 each extend over the entire length of their respective upper regions 720 , 740 and limit when the cushion is 7 ' in its folded-over state, on the connecting line. In an alternative embodiment, the struts extend 726 , 746 over part of the length of the respective upper area 720 , 740 and / or over the entire width of the respective upper area 720 , 740 away. Similar struts can be used in place of the struts 726 , 746 or in combination with it on the side 722 , 742 and / or the lower areas 724 , 744 be attached. The striving 726 , 746 are from one relatively stiff material, i.e. PMMA, is made. The striving 726 , 746 can alternatively be made of another rigid material, preferably a hard plastic material, such as. B. PVC, HDPE, polycarbonate or any combination thereof.

Both the first and the second area 72 , 74 include an adhesive on their back side that is from a first 728 and a second peelable adhesive cover 748 is covered. The back of the first area 72 with the first peelable adhesive cover 728 is the in 12th shown area. The adhesive assists in securing the pad in place 7 ' on the two inner sides and / or links of the mounting frame after removing the covers 728 , 748 . Here the adhesive is on the entire surface, with the exception of the area that is used by the struts 726 , 746 is covered, the back of both the first and second areas 72 , 74 upset. Alternatively, it can be applied to part of the surfaces, e.g. B. in local places or only at the edges of the areas 72 , 74 , be applied, or it can also be on the struts 726 , 746 be upset. The first 728 and the second cover 748 are divided into two pieces here, which can be detached individually, as in 12th in relation to the first cover 728 will be shown. Alternatively, the covers 728 , 748 can be made in one piece, or they can be made up of three or more pieces. As in 12th and 14th shown, the adhesive covers extend over the struts 726 , 746 away, although they are not attached to them. The covers 728 , 748 can in another embodiment only the zone of the back of the pad 7 ' covered with adhesive. The covers 728 , 748 are made from a paper material with a peelable coating, but they can also be made from any disposable sheet material suitable for contact with the adhesive.

In a further embodiment of the pad 7 " , in the 15th the first upper region of the first region (in 15th not shown) and the second upper area 740 ' of the second area 74 ' no striving. Instead, there is an adhesive on the entire surface of the first and second upper regions 740 ' provided, and the first (in 15th not shown) and the second pressure sensitive adhesive cover 748 are thus to the entire area of the first and the second area 74 ' stuck. Apart from this, the embodiment in FIG 15th those in the 12-14 .

As in 15th shown are the longitudinal ends of the first (not shown) and second upper portions 740 ' that point to connecting line A at an angle 9 to the end of the page area 742 angled. The angle 9 is about 45 degrees here, so that the adjacent first and second upper area meet 740 ' Can bend over about 90 degrees to the side areas when the pad 7 " is folded over. In this way, the adjacent upper regions together form an L-shaped upper region which is designed to extend parallel to the plane of the roof structure, while the side regions extend into the roof opening in a direction substantially perpendicular to the plane of the roof extend.

The same applies to the embodiment of the pad 7 ' , in the 12-14 will be shown. As in the 12-14 in terms of the upholstery 7 ' shown, this allows the ends of the side panels 720 , 740 border on connecting line A. This gives the upholstery 7 ' automatically the in 13th and 14th The shape shown, this shape being similar to the shape intended in the attached state. This also applies to the in 15th shown upholstery 7 " when in a folded state (not shown).

As in 15th is shown is a longitudinal end of the lower portion 744 pointing to connecting line A with respect to the end of the side area 742 angled but less than 45 degrees. This means that the lower areas bend somewhat with respect to the side areas in the folded-down state, as in FIG 13-14 can be seen, but not over 90 degrees, like the upper areas. Alternatively, the lower area 744 at an angle equal to the angle θ of the end of the upper range 740 ' resembles to be angled.

In a further embodiment (not shown) the longitudinal ends are the lower regions 724 , 744 not to the ends of the side panels 722 , 742 angled.

Instead are the lower areas 724 , 744 not connected at connecting line A, and the lower areas 724 , 744 therefore do not adjoin each other when folded down. In yet another embodiment (not shown) the pad 7 ' , 7 " no lower areas 724 , 744 on.
