Abstract

A weatherstrip with improved stackability has a rigid base portion including a planar surface and a flexible strip portion adhered over a corner of the base portion and extending outwardly at an angle to the planar surface of the base portion.

Claims

3-1. The weatherstrip of claim 1 wherein the base portion includes an angled edge opposite the corner of the base portion to which the strip portion is adhered.

10. A weatherstrip being a first weatherstrip comprising a rigid base portion including a planar surface and a flexible strip portion adhered over a corner of the base portion and extending outwardly at an angle to the planar surface of the base portion, wherein said first weatherstrip is stacked on a second weatherstrip having an identical structure, and wherein a strip portion of the second weatherstrip is free to angle outward without contacting a base portion of the first weatherstrip.

11. The weatherstrip of claim 10 wherein the strip portion of the first weatherstrip is tapered as progressively thinner from the corner of the base portion to an outermost edge of the strip portion furthest from the base portion.

12. The weatherstrip of claim 11 wherein the base portion of the first weatherstrip includes an angled edge opposite the corner of the base portion to which the strip portion is adhered.

13. The weatherstrip of claim 12 wherein the base portion of the first weatherstrip is cellular polyvinyl chloride and the strip portion of the first weatherstrip is non-cellular material.

14. The weatherstrip of claim 13 wherein the strip portion of the first weatherstrip is an extrudate and extrusion bonded to the corner of the base portion of the first weatherstrip.

15. A weatherstrip being a first weatherstrip comprising a rigid base portion including a planar surface and a flexible strip portion adhered over a corner of the base portion and extending outwardly at an angle to the planar surface of the base portion, wherein said first weatherstrip is stacked on a second weatherstrip having an identical structure, and wherein a strip portion of the second weatherstrip is free to angle outward with substantially no contact with a base portion of the first weatherstrip.

16. The weatherstrip of claim 15 wherein the strip portion of the first weatherstrip is tapered as progressively thinner from the corner of the base portion to an outermost edge of the strip portion furthest from the base portion.

17. The weatherstrip of claim 16 wherein the base portion of the first weatherstrip includes an angled edge opposite the corner of the base portion to which the strip portion is adhered.

18. The weatherstrip of claim 17 wherein the base portion of the first weatherstrip is cellular polyvinyl chloride and the strip portion of the first weatherstrip is non-cellular material.

19. The weatherstrip of claim 18 wherein the strip portion of the first weatherstrip is an extrudate and extrusion bonded to the corner of the base portion of the first weatherstrip.
