Abstract
A duct joining system for providing an air-tight seal and mechanical connection for ducts and fittings is disclosed. The duct joining system includes a flexible gasket affixed to a male end of a duct or fitting. The flexible gasket is affixed at an angle relative to normal of the male end of the duct. The female end of the other duct includes a raised bead in which the flexible gasket is seated when the ducts are properly joined. The angled flexible gasket seated in the raised bead forms an air-tight seal as well as fastens or locks the male end to the female end. Alternatively, when a flexible duct is used, a band clamp with a raised bead is clamped over the female end of the flexible duct and over the male end of a fitting to provide an air tight seal and fastened connection.
Claims21
A duct joining system comprising:
- a first duct having a male end and a flexible gasket coupled to said male end;
- and
- a second duct having a female end, said male end sliding into said female end, said second duct also having a raised bead on said female end, said raised bead being formed by at least two opposing sidewalls, said flexible gasket seats in said raised bead to form a seal with said female end and to fasten said male end to said female end.
A duct joining system comprising:
- a first duct comprising a male end and a flexible gasket coupled to said male end;
- a second duct comprising a female end, said male end sliding into said female end, said flexible gasket forming a seal with said female end, said second duct is a flexible duct;
- and
- a band clamp, said band clamp placed over said female end and said male end and clamps said first duct and said second duct together, said band clamp comprising a raised bead, said flexible gasket is seated in said second duct and said raised bead to form said seal with said female end and to fasten said male end to said female end.
An apparatus comprising:
- a first duct;
- a flexible gasket;
- means for affixing said flexible gasket to said first duct at an angle relative to the normal of said first duct;
- and
- a second duct having a raised bead being formed by at least two opposing sidewalls;
- wherein a portion of said first duct is inserted into a portion of said second duct and said flexible gasket seats in said raised bead and provides a seal and a mechanical connection between said first duct and said second duct.
A duct joining system comprising:
- a first duct having a male end;
- a second duct having a female end, said male end of said first duct being inserted into said female end;
- and
- means for mechanically fastening and sealing said first duct to said second duct, said means for mechanically fastening and sealing coupled to said first duct and said second duct and including a flexible gasket and a bead being formed by at least two opposing sidewalls in which said flexible gasket is seated when said male end is inserted into said female end.
