Abstract

Sealing strip (

1) for sealing a joint (

23) between a frame profile (

12), for example a window-frame profile, and a wall (

15), having an elastically resilient foam strip (

2) which is accommodated in a compressed state in a tear-open wrapper (

3), which allows recovery of the foam strip (

2). The tear-open wrapper (

3) comprises a plastic sheet (F) which encloses the foam strip (

2) and, at the same time, forms a tear-off flap (

4) extending in longitudinal direction of the sealing strip (

1).

Description

The subject matter of the invention is explained in more detail herein-below with reference to an exemplary embodiment illustrated in the figures, in which:

FIG. 1 shows a perspective illustration of a portion of a foam strip in its non-compressed state,

FIG. 2 shows, likewise in a schematic illustration, a portion of a sealing strip with encased foam strip, in the compressed state,

FIG. 3 shows a cross-section through a region of a frame profile in the direction of a wall with associated foam strip, accommodated in a bar,

FIG. 4 shows, on a vastly enlarged scale and broken away in layers, a plan view of a portion of the sealing strip,

FIG. 5 shows the section along line V—V in FIG. 4, and

FIG. 6 shows an enlargement from FIG. 6 (sic).

Claims

1. Sealing strip (

1) for sealing a joint (

23) between a frame profile (

12), and a wall (

15), having an elastically resilient foam strip (

2) which is accommodated in a compressed state in a tear-open wrapper (

3), which allows recovery of the foam strip (

2), wherein the tear-open wrapper (

3) comprises a plastic sheet (F) which encloses the foam strip (

2) and, at the same time, forms a tear-off flap (

4) extending in longitudinal direction of the sealing strip (

1), wherein the plastic sheet is arranged as a strip deflected about a longitudinally running fold and is attached to itself at a distance from said longitudinally running fold.

2. Sealing strip according to claim 1, wherein the plastics sheet (F) is attached to itself to form the tear-open wrapper (

3).

3. Sealing strip according to claim 1, wherein the foam strip is an open-cell PU foam strip (

2).

4. Sealing strip according to claim 1, wherein the foam strip (

2) is impregnated for delayed recovery.

5. Sealing strip according to claim 4, wherein impregnating agent is an acrylate.

6. Sealing strip according to claim 2, wherein attachment (

7) is formed by sewing.

7. Sealing strip according to claim 2, wherein attachment (

7) is formed by welding.

8. Sealing strip according to claim 2, wherein attachment (

7) is formed by adhesive bonding.

9. Sealing strip according to claim 1, wherein the foam strip (

2) is attached to the plastics sheet (F) inside the tear-open wrapper (

3).

10. Sealing strip according to claim 9, wherein attachment between the foam strip (

2) and plastics sheet (F) is formed by adhesive bonding.

11. Sealing strip according to claim 1, wherein a double-sided adhesive strip (

10) is disposed inside the tear-open wrapper (

3), the adhesive strip being adhesively bonded, on one side, to the plastics sheet (F) and, on the other side, to the foam strip (

2).

12. Sealing strip according to claim 1, wherein the sealing strip (

1) has a longitudinal adhesive strip (

11) on an outside for adhesive bonding to the frame profile (

12) or a bar (

13).

13. Sealing strip according to claim 12, wherein the longitudinal adhesive strip (

11) is disposed such that it overlaps an inside attachment between the foam strip (

2) and the plastics sheet (F).

14. Sealing strip according to claim 1, wherein the plastics sheet (F) is reinforced in a region of attachment between the foam strip (

2) and the plastics sheet (F) and/or of an outer longitudinal adhesive strip (

11).

15. Sealing strip according to claim 14, wherein reinforcement is formed by reinforcing filaments (

14).

16. Sealing strip according to claim 15, wherein the reinforcing filaments (

14) are disposed as a reinforcing network.

17. Sealing strip according to claim 14, wherein reinforcement is adhesively bonded to the plastics sheet (F).

18. Sealing strip according to claim 14, wherein reinforcement forms an intermediate layer between an inner double-sided adhesive strip (

10) and an inner surface of the plastics sheet (F).

19. Sealing strip according to claim 1, wherein the tear-off flap (

4) comprises two double-layer-forming ends of the plastics sheet (F).

20. Sealing strip according to claim 1, wherein the frame profile is a window frame profile.

21. Compressed foam strip (

2) which is disposed in a bar (

13) and is accommodated in a tear-open wrapper (

3), wherein a tear-off flap (

4), which is formed from the tear-open wrapper (

3) itself, the latter being in form of a plastics sheet (F), projects in an outward direction beyond the bar (

13) e to release compression.

22. Foam strip according to claim 21, wherein mount (

16), which is formed in the bar (

13), is of bench-like form in cross-section.

23. Foam strip according to claim 22, wherein parallel to a bench backrest (

17) of the mount (

16), but located opposite same, the bar (

13) has an adhesive surface (

20) for adhesive bonding to frame profile (

12).

24. Foam strip according to claim 21, wherein the bar (

13) is associated with frame profile (

12) such that it leaves a gap for the tear-off flap (

4).

25. Sealing strip (

1) for sealing a joint (

23) between a frame profile (

12) and a wall (

15), having an elastically resilient foam strip (

2) which is accommodated in a compressed state in a tear-open wrapper (

3), which allows recovery of the foam strip (

2), wherein the tear-open wrapper (

3) comprises a plastic sheet (F) which encloses the foam strip (

2) and, at the same time; forms a tear-off flap (

4) extending in a longitudinal direction of a sealing strip (

1), wherein the plastic sheet (F) is attached to itself to form the tear-open wrapper (

3) and the foam strip (

2) is attached to the plastic sheet (F) inside the tear-open wrapper (

3).

26. Sealing strip according to claims

25, wherein the frame profile is a window frame profile.
