Sealing or guiding assemblies and method of making it

1. A sealing or guiding assembly for sealing or guiding a corner of a closure member for an opening and for attachment to a frame for the opening, including;

strips of flexible material extending towards and meeting at an apex of the corner and shaped to receive the closure member at the corner and adapted to be supported by a corner support which forms part of the frame, and

a flap of flexible material joined to the strips of flexible material in a region of the corner and bridging across the corner between the strips,

wherein the strips each include a first lip extending from a proximal region of the flap and a second lip extending from an end region of the flap with the second lip bridging across the corner between the strips such that at least one of the first and second lips sealingly engages the closure member, the arrangement being such that an outer join at the end region of the flap is disposed under the second lip.

2. The assembly of claim 1 , wherein an inner join at the proximal region of the flap is disposed under one of the first lips of one of the strips.

3. The assembly of claim 2 , wherein two sides of the flap are joined to respective sides of the strips in the region of the corner with the sides of the flap extending toward the apex of the corner and inner joins at the sides of the flap being disposed under respective first lips of the strips.

4. The assembly of claim 3 , wherein the outer join bridges across the corner between the sides of the flap such that the second lip bridges angularly across the corner with the outer join disposed under the second lip.

5. The assembly of claim 1 , wherein the strips include at least one further lip for clampingly engaging the frame.

6. The assembly of claim 1 , wherein the strips include a resiliently deformable protrusion for engaging a recess of the frame for serving to locate the strips with respect to the frame.

7. The assembly of claim 1 , wherein the strips include a channel for grippingly engaging a flange of the frame.

8. The assembly of claim 1 , wherein the flap is formed of moulded material.

9. The assembly of claim 1 , wherein the flap is moulded onto the strips.

10. The assembly of claim 1 , wherein the strips are formed of extruded material.

11. The assembly of claim 1 , wherein at least one of the flap and the strips comprise at least one of EPDM and TPE.

12. The assembly of claim 1 , wherein the flap is compressible or extendable/stretchable in order to allow it to extend over the corner support.

13. The assembly of claim 12 , wherein the flap includes a reduced thickness portion to provide the compressibility or extendibility.

14. The assembly of claim 1 , wherein a distal end of each of the strips have an embedded rigid member therein for reducing the tendency of the distal end to bend.

15. The assembly of claim 1 , in which at least one of the flap and the strips include a formation for engaging the corner support.

16. The assembly of claim 15 , wherein the formation comprises a protrusion with a resiliently deformable enlarged head portion.

17. The assembly of claim 16 , in which the corner support includes an aperture with which the protrusion engages.

18. The assembly of claim 16 , wherein the formation is formed from material which is harder than the flexible material forming other parts of the strips.

19. The assembly of claim 16 , wherein the protrusion has a rigid member embedded therein.

20. The assembly of claim 15 , wherein the formation is integrally formed with at least one of the strips.

21. The assembly of claim 15 , wherein the formation is integrally formed with the flap.

22. The assembly of claim 21 , wherein the formation comprises a recess.

23. The assembly of claim 22 , wherein the corner support includes an engagement part for abutting a surface of the recess.

24. A sealing or guiding assembly for sealing or guiding a corner of a closure member for an opening and for attachment to a frame for the opening, including;

strips of flexible material extending towards and meeting at an apex of the corner and shaped to receive the closure member at the corner and adapted to be supported by a corner support which forms part of the frame, and

a flap of flexible material having two sides joined to respective sides of the strips of flexible material in a region of the corner with the flap bridging across the corner between the strips,

wherein the strips include a first lip extending towards the apex of the corner and a second lip extending from an end region of the flap of flexible material that bridges across the corner between the strips such that the second lip is spaced from the apex of the corner, the first and second lips being for sealingly engaging the closure member with an outer join at the end region of the flap being disposed under the second lip.

25. A sealing or guiding assembly for sealing or guiding a corner of a closure member for an opening and for attachment to a frame for the opening, including;

strips of flexible material extending towards and meeting at an apex of the corner and shaped to receive the closure member at the corner and adapted to be supported by a corner support which forms part of the frame, and

a flap of flexible material having two sides joined to respective sides of the strips of flexible material in a region of the corner with the flap bridging across the corner between the strips,

wherein the strips include a first lip extending towards the apex of the corner and a second lip extending from an end region of the flap of flexible material that bridges across the corner between the strips for sealingly engaging the closure member with inner joins at the sides of the flap being disposed under respective first lips of the strips and an outer join at the end region of the flap being disposed under the second lip with the outer join bridging across the corner between the sides of the flap.
