Abstract
Internal connectors are configured to conformingly fit within each of the mating ends of adjacent duct elements. The internal connectors each comprise a sleeve having an outwardly extended wall disposed about a perimeter of the internal connector. The mating ends each have a stepped face configured to conformingly mate with the internal connector. To connect the duct elements together, the mating ends are mated to each side of the internal connector and the mating ends are glued to each other. Because the mating ends and the internal connectors conformingly mate with each other, the duct elements will be aligned with each other. The internal connectors are glued to a side wall of the duct element wherever branch take-offs are made.
Claims4
A duct system comprising:
- at least one connector comprising a generally rectangular sleeve having a pair of outwardly extending wall portions disposed about a perimeter of said sleeve;
- each said outwardly extending wall portion defining a first double stepped portion comprised of a pair of outwardly facing step surfaces and an intervening surface;
- a plurality of duct elements, each of said duct elements having at least one generally rectangular mating end, each of said mating ends having a second double stepped portion configured to engage one of said first double stepped portions by conformingly mating with the respective said pair of outwardly facing step surfaces and said intervening surface, and said connector being configured to conformingly fit within said mating ends, respectively;
- wherein said duct elements can be aligned and connected together by fitting one of said at least one connector within said mating ends of two of said duct elements and gluing the respective said mating ends to each other.
A method of assembling a portion of a duct system comprising:
- providing at least one connector comprising a generally rectangular sleeve having a pair of outwardly extending wall portions disposed about a perimeter of said sleeve, wherein each said outwardly extending wall portion defines a first double stepped portion comprised of a pair of outwardly facing step surfaces and an intervening surface;
- providing a plurality of duct elements, each of said duct elements having at least one generally rectangular mating end, each of said mating ends having a second double stepped portion configured to engage one of said first double stepped portions by conformingly mating with the respective said pair of outwardly facing step surfaces and said intervening surface, and said connector being configured to conformingly fit within said mating ends, respectively;
- fitting one of said at least one connector within said mating ends of two of said duct elements to align said duct elements, and gluing the respective said mating ends to each other.
