Abstract

An extruded interlocking flexible gasket with a first side with at a least one first side spline and at least one first side groove on the gasket to be positioned between a first member and a second member. The gasket further having a second side with at a least one second side spline and at least second first side groove on said extruded gasket, wherein said first side interlocks with said second side when said first side is immediately adjacent to said second permitting the at a least one first side spline to be interlocked with at least the second side groove, and extending continuously therealong.

First claim

What is claimed is:

1. An extruded interlocking flexible gasket comprising:
a first side with a first side spline and a first side groove to be positioned between a first member and a second member; and
a second side with a second side spline and a second side groove,
wherein said gasket is formed from a resilient and compressible material,
wherein an imaginary centerline extends between said first and second side grooves and said first and second side grooves do not cross said imaginary centerline,
wherein said first side interlocks with said second side when said first side overlaps said second side.

2. The interlocking flexible gasket of claim 1 , wherein said gasket is positioned in a groove in a first surface of said first member, wherein said gasket wraps around said groove in said first surface of said first member and said first side of said gasket overlaps said second side of the gasket to produce a seal between said first member and said second member.

3. The interlocking flexible gasket of claim 1 , wherein said splines and said grooves further interlock as said first member is compressed upon said second member in order to seal said first member to said second member.

4. The interlocking flexible gasket of claim 1 , wherein said first side groove has an opening, said opening having a width less than a maximum width of said second side spline in order to prevent disengagement of said second side spline from said first side groove along a longitudinal direction of said flexible gasket.

5. The interlocking flexible gasket of claim 1 , wherein said gasket has an elliptical cross-sectional shape permitting a maximum first longitudinal movement when said gasket is compressed in a second longitudinal direction.

6. The interlocking flexible gasket of claim 1 , wherein said resilient and compressible material is selected from the group consisting of an inorganic polymer, an organic polymer, a copolymer, a fluoropolymer, a polyester, a rubber, a silicone rubber, a synthetic rubber, and a vinyl polymer.

7. A method to seal the junction between two surfaces, comprising:
loading at least one of a polymer mixture, a filler, an activator, an accelerator, a bonding promoter, a curative compound, and a pigment into a extruding device;
mixing the at least one of said polymer mixture, said filler, said activator, said accelerator, said bonding promoter, said curative compound, and said pigment to form an elastomer;
feeding the elastomer into an extruder;
extruding said elastomer though a die to form a gasket; and
positioning said gasket in a groove in a first surface, wherein said gasket wraps around said groove in said first surface and a first end of the gasket overlaps a second end of the gasket;
placing a second surface on said gasket and said first surface, thereby sealing the first surface to the second surface.

8. The method of claim 7 , wherein the polymer mixture is a least one of an inorganic polymer, an organic polymer, a copolymer, a fluoropolymer, a polyester, a rubber, a silicone rubber, a synthetic rubber, and a vinyl polymer.

9. The method of claim 7 , further comprising, heating the extruder.

10. The method of claim 7 , wherein the extruder is at least a screw extruder and a ram extruder.

11. The method of claim 7 , further comprising, shaping the gasket with the die, wherein die produces said gasket with a first side with at a least one first side spline and at least one first side groove, and a second side with a second side spline and a second side groove.

12. The method of claim 7 , further comprising, compressing said gasket as the first surface is positioned adjacent to the second surface, thereby further interlocking said first side spline and said first side groove as the first surface is attached to the second surface.

13. A system for sealing the junction between two surfaces, comprising:
means for loading at least one of a polymer mixture, a filler, an activator, an accelerator, a bonding promoter, a curative compound, and a pigment into a extruding device;
means for mixing the at least one of said polymer mixture, said filler, said activator, said accelerator, said bonding promoter, said curative compound, and said pigment to form an elastomer;
means for feeding the elastomer into an extruder;
means for extruding said elastomer though a die to form a gasket; and
means for positioning said gasket in a groove in a first surface, wherein said gasket wraps around said groove in said first surface and a first end of the gasket overlaps a second end of the gasket;
means for placing a second surface on said gasket and said first surface, thereby sealing the first surface to the second surface.

14. The system of claim 13 , wherein the polymer mixture is a least one of an inorganic polymer, an organic polymer, a copolymer, a fluoropolymer, a polyester, a rubber, a silicone rubber, a synthetic rubber, and a vinyl polymer.

15. The system of claim 13 , further comprising, means for heating the extruder.

16. The system of claim 13 , wherein the extruder is at least a screw extruder and a ram extruder.

17. The system of claim 13 , further comprising, means for shaping the gasket with the die, wherein die shapes said gasket with a first side with at a least one first side spline and at least one first side groove, and a second side with a second side spline and a second side groove.

18. The system of claim 13 , further comprising, means for compressing said gasket as the first surface is positioned adjacent to the second surface, thereby further interlocking said first side spline and said first side groove as the first surface is attached to the second surface.
