Abstract
A duct support assembly includes first and second spaced rings joined by a plurality of circumferentially spaced links. First and second means pivotally join the links to the first and second rings, and the links may be assembled through an outer surface of the first ring and are adjustable from the first ring outer surface.
Claims14
A duct support assembly comprising:
- a) a first ring having an outer surface;
- b) a second ring spaced radially inwardly from said first ring to define an annual duct there between;
- c) a plurality of circumferentially spaced links joining said first and second rings, each of said links comprising a bolt having a first end, and a second end wherein:
- i) said bolts are aligned generally tangentially to said second ring,
- ii) said first end comprises a bolt head, and said bolt is rotationally adjustable for preloading said bolt in tension from said first ring outer surface;
- d) first means for pivotally joining said link first ends to said first ring wherein said first joining means includes:
- i) a partly spherical bearing surface on said bolt head facing toward said first ring outer surface,
- ii) a bearing seat fixedly joined to said first ring and being complimentary to said bearing surface, said seat including a central aperture receiving said bolt and allowing said bearing surface to slideably contact said seat, and
- iii) a bracket fixedly secured to said first ring, wherein said bracket includes;
- A) an outer surface defining said bearing seat,
- B) an inclined bore extending through said bracket for receiving said bolt, and
- C) a base having an outer surface including said bearing seat, an inner surface contacting said first ring outer surface, and a platform extending from said base toward said second ring and disposed in a complimentary slot in said first ring;
- and
- e) second means for pivotally joining said link second ends to said second ring.
