Abstract

A sealing gasket (4) for use between flashing members (31,32) is disclosed. It comprises a compressible sealing section and an attachment section comprising at least two legs configured for engagement with a flashing member, both sections extending over substantially the entire length of the sealing gasket. The at least two legs of the attachment section project from a base section of the attachment section so that a first recess and a second recess extending in parallel are defined, said first and second recesses being configured for engagement with a flange, ridge, or leg on a flashing member. The invention further relates to a flashing arrangement and to a method of sealing a gap between flashing members for a roof window.

First claim

The invention claimed is:

1. A sealing gasket for use between flashing members, comprising a compressible sealing section and an attachment section comprising at least two legs configured for engagement with a flashing member, said sealing gasket having a length direction and a width direction extending perpendicular to the length direction, and said compressible sealing section and said attachment section both extending over substantially an entire length of the sealing gasket when viewed in the length direction,
the compressible sealing section having an outer inclined surface, two cavities arranged next to each other when viewed in the width direction and an inner wall, said inner wall being disposed between the two cavities, where each of the outer inclined surface, the two cavities and the inner wall extend over the entire length of the sealing gasket, the compressible sealing section further having a bottom wall extending in the width direction across a width of the inner wall and a width of each of the two cavities, the bottom wall being disposed below a lowermost portion of each of the two cavities and a lowermost portion of the inner wall, and
the at least two legs of the attachment section project from a base section of the attachment section in a height direction, which is perpendicular to the length direction and the width direction, each leg of the at least two legs has a free edge furthest from the base section, and that the at least two legs project substantially in parallel, so that a first recess extending in the length direction is defined between the at least two legs, and that said attachment section comprises a second recess extending in parallel with the first recess, said first and second recesses being configured for engagement with one of a flange, a ridge, and a leg on a flashing member.

2. The sealing gasket according to claim 1 , where the attachment section comprises at least one further leg extending in parallel with the at least two legs, and where at least one further recess extending in parallel with the first and second recesses is delimited by the at least one further leg.

3. The sealing gasket according to claim 2 , where the first recess, the second recess, the at least one further recess, and the compressible sealing section are arranged in a row when viewed in the width direction.

4. The sealing gasket according to claim 3 , where the compressible sealing section extends outwardly from the attachment section.

5. The sealing gasket according to claim 3 , where the outer inclined surface forms a side of the compressible sealing section furthest from the attachment section when viewed in the width direction to drain off water.

6. The sealing gasket according to claim 3 , where at least one leg of the at least two legs of the attachment section is provided with a thickening or projection so that a width of a respective recess of the first and second recesses at free edges of the at least two legs is smaller than a width of the respective recess closer to the base section.

7. The sealing gasket according to claim 3 , where the at least two legs of the attachment section are made from a resilient material allowing the legs to bend about an axis, which is substantially parallel to the length direction, and automatically return towards an original position of the at least two legs.

8. The sealing gasket according to claim 2 , where each of said two cavities are disposed between said inclined outer surface and the attachment section.

9. The sealing gasket according to claim 2 , where the compressible sealing section extends outwardly from the attachment section.

10. The sealing gasket according to claim 2 , where the outer inclined surface forms a side of the compressible sealing section furthest from the attachment section when viewed in the width direction to drain off water.

11. The sealing gasket according to claim 2 , where at least one leg of the at least two legs of the attachment section is provided with a thickening or projection so that a width of a respective recess at free edges of the at least two legs is smaller than a width of the respective recess of the first and second recesses closer to the base section.

12. The sealing gasket according to claim 2 , where the at least two legs of the attachment section are made from a resilient material allowing the legs to bend about an axis, which is substantially parallel to the length direction, and automatically return towards an original position of the at least two legs.

13. The sealing gasket according to claim 1 , where the compressible sealing section extends outwardly from the attachment section.

14. The sealing gasket according to claim 1 , where at least one leg of the at least two legs of the attachment section is provided with a thickening or projection so that a width of a respective recess of the first and second recesses at free edges of the at least two legs is smaller than a width of the respective recess of the first and second recesses closer to the base section.

15. The sealing gasket according to claim 1 , where the at least two legs of the attachment section are made from a resilient material allowing the legs to bend about an axis, which is substantially parallel to the length direction, and automatically return towards an original position of the at least two legs.

16. The sealing gasket according to claim 1 , where the first recess, the second recess, and the compressible sealing section are arranged in a row when viewed in the width direction.

17. A roof window assembly including at least one roof window having a frame, at least two flashing members and at least one sealing gasket, the at least one sealing gasket comprising a compressible sealing section and an attachment section comprising at least two legs engaging one of the at least two flashing members, said at least one sealing gasket having a length direction and a width direction extending perpendicular to the length direction, and said compressible sealing section and said attachment section both extending over substantially an entire length of the at least one sealing gasket when viewed in the length direction,
the at least two legs of the attachment section project from a base section of the attachment section in a height direction, which is perpendicular to the length direction and the width direction, each leg of the at least two legs has a free edge furthest from the base section, and that the at least two legs project substantially in parallel, so that a first recess extending in the length direction is defined between the at least two legs, and said attachment section comprises a second recess extending in parallel with the first recess, said first recess receiving and engaging one of a flange, a ridge, and a leg of a first flashing member of the at least two flashing members when the at least one sealing gasket is in a first operational position and said second recess receiving and engaging one of the flange, the ridge, and the leg of the first flashing member of the at least two flashing members when the at least one sealing gasket is in a second operational position, wherein the second operational position is different from the first operational position,
where the compressible sealing section of the at least one sealing gasket contacts each of the at least two flashing members and closes a gap between them and where one of the flange, the ridge, and the leg of the first flashing member projects into a corresponding recess of the first and second recesses of the attachment section.
