Abstract

A generally L-shaped corner seal includes an elongated leg comprising a material having a first hardness and an integral shorter leg comprising a material having a second hardness less than the first hardness.

Claims

1. A generally L-shaped corner seal for a hinged panel comprising:

an elongated leg comprising a material having a first hardness; and

an integral shorter leg comprising a material having a second hardness less than the first hardness.

2. The corner seal of claim 1 wherein the first leg comprises an adhesive layer.

3. The corner seal of claim 1 wherein the first leg comprises a tapered leg having a thicker portion abutting the second leg, and a thinner distal portion.

4. The corner seal of claim 1 wherein the first leg comprises foam.

5. The corner seal of claim 4 wherein the foam comprises closed cell foam.

6. The corner seal of claim 1 wherein the second leg comprises foam.

7. The corner seal of claim 6, wherein the second leg comprises closed cell foam.

8. The corner seal of claim 1 further comprising a lip projecting from the second leg at a substantially right angle.

9. The corner seal of claim 4, further comprising a fabric layer on the foam.

10. The corner seal of claim 6, further comprising a fabric layer on the foam.

11. The corner seal of claim 1, further comprising a continuous fabric layer covering the first and second legs.

12. The corner seal of claim 11, wherein the continuous fabric layer surrounds the first and second legs.

13. The corner seal of claim 1, wherein the first hardness is in a range of from about 5 durometer to about 20 durometer.

14. The corner seal of claim 1, wherein the second hardness is in a range of from about 20 durometer to about 35 durometer.

15. A seal for use between confronting members movable with respect to each other, the seal comprising:

a first portion comprising a material having a first hardness; and

a second portion formed integrally with the first portion and comprising a material having a second hardness.

16. The seal of claim 15 having a substantially L-shape, the first portion comprising a first leg and the second portion comprising a second leg substantially perpendicular to the first leg.

17. A method of manufacturing a corner seal, comprising

providing a first material having a first hardness;

providing a second material having a second hardness; and

coextruding the first material and the second material through a single die to form a unitary structure.

18. The method of claim 17 further comprising applying a slip coat over a portion of one or both of the first material and the second material.

19. The method of claim 18, further comprising applying a pressure sensitive adhesive on a portion of at least one of the first material, the second material, and the slip coat.
