Seal with two sealing portions having flange receiving opening therebetween

Abstract

An integral ring-shaped seal adapted to be carried at the end of a connector housing and provide two spaced-apart sealing portions, said two spaced-apart sealing portions being connected by a web, and said two spaced-apart sealing portions together with said web providing therebetween an opening adapted to receive a flange located in proximity to the end of the connector housing, at least one of said two spaced-apart sealing portions having a cut-out axially disposed away from said opening to provide increased resiliency and wear resistance.

We claim: .[.1. An integral ring-shaped seal adapted to be carried at the end of a connector housing and provide two spaced-apart sealing portions, said two spaced-apart sealing portions being connected by a web, and said two spaced-apart sealing portions together with said web providing therebetween an opening adapted to receive a flange located in proximity to the end of the connector housing, at least one of said two spaced-apart sealing portions having a cut-out axially disposed away from said opening to provide increased resiliency and wear resistance..]. .[.2. The construction of claim 1 wherein said opening is a slot..]. .[.3. The construction of claim 1 wherein there are two symmetric axial cut-outs which open at opposite sides of the seal..]. .[.4. The construction of 
     
        claim 1 wherein there is one axial cut-out..]. .[.5.  The novel combination comprising telescoping connector housing sections one of which has an upstanding annular flange located in proximity to its open end, and an integral ring-shaped seal carried at the end of one of said connector housing, said seal having two spaced-apart sealing portions, said two spaced-apart sealing portions being connected by a web, and said two spaced-apart sealing portions together with said web providing therebetween an opening, said flange being received in said opening, at least one of said two spaced-apart sealing portions having a cut-out axially disposed away from said opening to provide increased resilency and wear resistance..]. .[.6. The construction of claim 5 wherein the seal has an L-shaped cross-section, one leg of which abuts the side of the flange and the other leg abuts the surface of one of its sides and the end of the flange on the other..]. .[.7. The construction of claim 5 wherein said opening is a slot..]. .[.8. The construction of claim 5 wherein there are two symmetric axial cut-outs which open at opposite sides of the seal..]. .[.9. The construction of claim 5 wherein there is one axial cut-out..]. .[.10. The construction of claim 5 where one of said telescoping sections has two adjacent "L" shaped flange sections, one of which is received in said opening in the seal and the other positioned to abut the end of said seal, both of said flange sections being adhered to the cylindrical surface of said telescoping section..]. .[.11. The construction of claim 10 wherein the flanges are on the interior of said telescoping section..]. .[.12. The construction of claim 10 wherein the flanges are on the 
     
     
        exterior of said telescoping section..]. .Iadd.13.  In the ducts of commercial jet aircraft, the improvement comprising: a novel combination forming part of said ducts and comprising telescoping flexible connector housing sections one of which has an upstanding annular flange located in proximity to the open end of the connector housing, and an integral, flexible, fiber-reinforced elastomeric ring-shaped seal carried at the end of one of said connector housing, said seal having two spaced-apart sealing portions, said two spaced-apart sealing portions being connected by a web, and said two spaced-apart sealing portions together with said web providing therebetween an opening, said flange being received in said opening, at least one of said two spaced-apart sealing portions having a cut-out axially disposed away from said opening to provide increased resiliency and wear resistance, said connector housing sections being adapted to undergo flex due to thermal cycling and other stresses. .Iaddend. .Iadd.14. The improvement of claim 13, wherein the seal has an L-shaped cross-section, one leg of which abuts the side of the flange and the other leg abuts the surface of one of its sides and the end of the flange on the other. .Iaddend. .Iadd.15. The improvement of claim 13, wherein said opening is a slot. .Iaddend. .Iadd.16. The improvement of claim 13, wherein there are two symmetric axial cut-outs which open at opposite sides of the seal. .Iaddend. .Iadd.17. The improvement of claim 13, wherein there is one axial cut-out. .Iaddend. .Iadd.18. The improvement of claim 13, wherein one of said telescoping sections has two adjacent "L" shaped flange sections, one of which is received in said opening in the seal and the other positioned to abut the end of said seal, both of said flange sections being adhered to the cylindrical surface of said telescoping section. .Iaddend. .Iadd.19. The improvement of claim 18, wherein the flanges are on the interior of said telescoping section. .Iaddend. .Iadd.20. The improvement of claim 18, wherein the flanges are on the exterior of said telescoping section. .Iaddend.
