Abstract

A magnetic door gasket (10) having a central web (18) and three enclosed chambers (12, 14, 16) projecting from a first side of the web, and a U-shaped recess (20) formed by the web and a leg (22) spaced from the opposed side of the web and joined thereto by a bight (26). The leg has a U-shaped projection (24) projecting therefrom partly to the web, the projection being spaced from the bight. The projection has a nib (28) projecting obliquely from a closed end (30) toward the web and the bight. The gasket is formed from a resilient material, such as PVC, by extrusion.

Claims

1. A gasket for sealing a juncture between a door and a cabinet to which the door is hingedly connected, said gasket being formed from a resilient material and being adapted to be attached to a panel of the door, said gasket having a cross-sectional configuration comprising:

a central web;

a plurality of enclosed chambers extending from a first side of said central web;

a leg spaced from a second side of said central web and extending generally parallel thereto;

a bight joining an end of said leg and an end of said central web and forming a generally U-shaped recess with said leg and said web;

a generally U-shaped projection extending partly from said leg toward said web, said generally U-shaped projection being spaced from said bight and having a closed end positioned adjacent to, but spaced from, said web; and

a nib extending from said closed end of said generally U-shaped projection toward said central web, said nib being adapted to impede disengagement of said gasket from the panel of the door during assembly of said gasket to the door.

2. A gasket according to claim 1 which is formed integrally by extrusion from a resilient material.

3. A gasket according to claim 2 wherein the resilient material is polyvinyl chloride.

4. A gasket according to claim 3 wherein said nib extends obliquely from said closed end toward said bight.

5. A gasket according to claim 4 wherein said plurality of enclosed chambers includes a generally rectangular chamber, said generally rectangular chamber being adapted to contain a magnetic insert.

6. A gasket according to claim 5 wherein said plurality of enclosed chambers consists of three enclosed chambers disposed in a triangular array.

7. A gasket according to claim 3 wherein said plurality of enclosed chambers includes a generally rectangular chamber, said generally rectangular chamber being adapted to contain a magnetic insert.

8. A gasket according to claim 7 wherein said plurality of enclosed chambers consists of three enclosed chambers disposed in a triangular array.

9. A gasket according to claim 2 wherein said nib extends obliquely from said closed end toward said bight.

10. A gasket according to claim 9 wherein said plurality of enclosed chambers includes a generally rectangular chamber, said generally rectangular chamber being adapted to contain a magnetic insert.

11. A gasket according to claim 10 wherein said plurality of enclosed chambers consists of three enclosed chambers disposed in a triangular array.

12. A gasket according to claim 2 wherein said plurality of enclosed chambers includes a generally rectangular chamber, said generally rectangular chamber being adapted to contain a magnetic insert.

13. A gasket according to claim 12 wherein said plurality of enclosed chambers consists of three enclosed chambers disposed in a triangular array.

14. A gasket according to claim 1 wherein said nib extends obliquely from said closed end toward said bight.

15. A gasket according to claim 14 wherein said plurality of enclosed chambers includes a generally rectangular chamber, said generally rectangular chamber being adapted to contain a magnetic insert.

16. A gasket according to claim 15 wherein said plurality of enclosed chambers consists of three enclosed chambers disposed in a triangular array.

17. A gasket according to claim 1 wherein said plurality of enclosed chambers includes a generally rectangular chamber, said generally rectangular chamber being adapted to contain a magnetic insert.

18. A gasket according to claim 17 wherein said plurality of enclosed chambers consists of three enclosed chambers disposed in a triangular array.

19. In combination with a panel of a door of a refrigerator a gasket attached to said panel for sealing a juncture between the door and a cabinet to which the door is hingedly connected, said gasket being formed from a resilient material and having a cross-sectional configuration comprising:

a central web;

a plurality of enclosed chambers extending from a first side of said central web;

a leg spaced from a second side of said central web and extending generally parallel thereto;

a bight joining an end of said leg and an end of said central web and forming a generally U-shaped recess with said leg and said web;

a generally U-shaped projection extending partly from said leg toward said web, said generally U-shaped projection being spaced from said bight and having a closed end positioned adjacent to, but spaced from, said web; and

a nib extending from said closed end of said generally U-shaped projection toward said central web, said nib engaging said panel of the door during assembly of said gasket to the door to prevent disengagement of said gasket from said panel.

20. A combination according to claim 19 wherein said gasket is formed integrally by extrusion from polyvinyl chloride.

21. A combination according to claim 20 wherein said nib of said gasket extends obliquely from said closed end toward said bight.
