Abstract

A connector to receive the top and bottom member of a duct system.

Claims

1. A connector for sealingly connecting adjacent ends of aligned ducts comprising an inner member of sheet material in the form of an elongated strip having a central portion and a width to bridge the space between the adjacent ends of the ducts, each side edge of said strip which fits into an end of a duct including a shallow angulated portion facing outwardly and having terminal ends thereon for sealing contact with the inner surface of the end of each duct at areas spaced from said central portion and extending throughout the length of said strip, an outer member, and means securing said outer member to said central portion of said inner member, said outer member being coextensive with said inner member, said outer member having side edges in opposed relation to the central portion of the inner member for engagement with the outer surface of the duct to retain the terminal ends of the angulated portion of the inner member in sealing contact with the inner surface of the duct.

2. The connector of claim 1 wherein the inner surface of said inner member is substantially smooth with the angulated portions presenting shallow inclined surfaces to air flow through the duct.

3. The connector of claim 1 wherein said outer member includes outwardly extending flanges to reinforce said connector and adjacent ends of the ducts.
