Abstract
A flanged ring connector (50) for connecting adjacent ends of HVAC ducting (52) includes an insertion flange portion to engage within the interior of the ducting. A mating flange portion (56) extends laterally or transversely to the insertion flange portion (54). A seat (58) is formed along the mating flange portion (56) to receive and retain a seal (60) and/or a reinforcing member or bead (90).
Claims19
A flanged ring connector to join adjacent ducts in an HVAC system, the flange ring connector comprising:
- a. a first mating flange defining a first mating face, said first mating flange defining an outer perimeter portion and an inner perimeter portion;
- b. a first insertion flange extending laterally from the inner perimeter portion of the first mating flange, said first insertion flange having an inside surface and an outside surface, said first insertion flange having a sufficient length to allow fixed attachment to an HVAC duct;
- c. a first formed seat extending along the first mating flange, said first seat defining an interior cavity sized and shaped to receive a first seal within the first seat;
- and
- d. the first seal disposed and held within the interior of the first seat and projecting from the first seat beyond the first mating face in the direction opposite to the direction that the insertion flange extends from the first mating flange to be in position to mate with a corresponding seal of a flanged ring connector of an adjacent HVAC duct.
A flanged ring connector to join ducts in an HVAC system, the flange ring connector comprising:
- a. a mating flange defining an outer perimeter portion and an inner perimeter portion;
- b. an insertion flange extending laterally from the inner perimeter portion of the mating flange, said insertion flange having an inside surface and an outside surface, said insertion flange having a sufficient length to allow fixed attachment to an HVAC duct;
- c. wherein said mating flange defines a mating face on the side of the mating flange opposite to the direction that the insertion flange projects from the mating flange and a second face on the side of the mating flange opposite to the mating face;
- and
- d. a compressible seal disposed about the outer perimeter portion of the mating flange, said seal having portions overlapping and attached to the mating flange mating face and mating flange second face.
A flanged ring connector to join ducts in an HVAC system, the flange ring connector comprising:
- a. a mating flange defining an outer perimeter portion and an inner perimeter portion;
- b. an insertion flange extending laterally from the inner perimeter portion of the mating flange, said insertion flange having an inside surface and an outside surface, said insertion flange having a sufficient length to allow fixed attachment to an HVAC duct;
- c. a formed first seat extending along the mating flange to define an interior cavity;
- d. a reinforcing member disposed within the interior cavity of the first seat to increase the structural integrity of the flanged ring connector;
- and
- e. a compressible seal also disposed within the interior cavity of the first seat, said compressible seat projecting from the first seat beyond the mating flange in the direction opposite to the direction that the insertion flange extends from the mating flange.
