Abstract
A sleeve assembly for supporting flexible duct includes a frame with first and second frame sections. The frame sections are secured together by fastener subassemblies. The sleeve assembly accommodates flexible duct in various angular and straight configurations. The frame can comprise various suitable materials and skeletal or solid-exterior construction. The sleeve assembly is adapted for various installations in air distribution systems of heating, ventilating and air conditioning systems.
Claims20
In combination with an air handling system of a heating, ventilating and air conditioning system, including a supply duct, a diffuser and a length of flexible hose interconnecting same and including an arcuate bend, the improvement of a sleeve assembly which comprises:
- a) first and second ends;
- b) a passage extending between and open at said ends, said passage selectively receiving the length of flexible duct;
- c) a frame generally conforming to the exterior shape of the flexible duct and including first and second frame sections;
- and
- d) a frame fastener for securing said first and second frame sections together with the length of flexible duct located in said passage.
In combination with an air handling system of a heating, ventilating and air conditioning system including a supply duct, a diffuser and a length of flexible duct interconnecting same and including an arcuate bend, the improvement of a sleeve assembly which comprises:
- a) a frame including:
- 1) opposite first and second ends;
- 2) an inner radius frame section including an inner radius arc extending between said ends;
- 3) an inner radius frame section including an outer radius arc extending between said ends;
- 4) an arcuate longitude axis extending between said ends in generally parallel relation with respect to said arcs;
- 5) a plurality of annular rings, including a first end ring located adjacent to said frame first end, a second end ring located adjacent to said frame second end and an intermediate ring located between said end rings;
- 6) each said ring lying generally in a plane perpendicular to said longitudinal axis;
- 7) each said ring comprising an inner rib of said inner radius frame section and an outer rib of said outer radius frame section;
- 8) each said frame section including a pair of arcuate side edges;
- and
- 9) a passage extending between and open at said ends, said passage receiving said flexible duct;
- and
- b) a plurality of fastener subassemblies each mounted on said frame adjacent to said section side edges, each said fastener subassembly having an open position with said frame sections disengaged and a closed position with said frame sections engaged.
A sleeve for a length of flexible duct, which comprises:
- a) first and second ends;
- b) a passage extending between and open at said ends, said passage selectively receiving the length of flexible duct;
- c) a frame generally conforming to the exterior shape of the flexible duct and including first and second frame sections;
- d) a frame fastener for securing said first and second frame sections together with the length of flexible duct located in said passage;
- e) a frame having a longitudinal axis extending between said sleeve ends and a curved configuration curving through an angle in the range of approximately 15 degrees to 180 degrees;
- f) said sleeve ends lie in respective planes generally perpendicular to said sleeve axis;
- g) said frame including said first and second end rings located at said sleeve first and second ends respectively and an intermediate ring located intermediate said first and second end rings;
- h) a plurality of longitudinal members extending between and connecting said rings, said longitudinal members extending in generally parallel relation with respect to said longitudinal axis;
- i) said ring comprises a pair of ribs, each said rib being located in a respective frame section;
- j) a plurality of loops each mounted on a respective rib of a respective end ring;
- and
- k) a pair of ties each encircling a respective end ring, said ties being received in said loops.
