Patent ID: 7401754

Claim:
A system for supporting a member on a support post, the support post being generally circular when viewed in radial cross-section, said system comprising: a sleeve having an inner surface generally circular in cross-section to embrace the support post and an outer surface formed with a first axially outwardly inclined portion and at least one second axially outwardly inclined portion that, when viewed in radial cross-section, extends at an angle to said first inclined portion; and a collar adapted to be secured to the member and embrace said sleeve, said collar having a first wedge surface formed to mate with said first inclined portion of said outer surface of said sleeve and at least one second wedge surface formed to mate with said second inclined portion of said outer surface of said sleeve; wherein, when said sleeve embraces the post and said collar embraces said sleeve, axial loading of said collar in one direction causes said first wedge surface to mate with said first inclined portion of the outer surface of said sleeve and said second wedge surface to mate with said second inclined portion of the outer surface of the sleeve, thereby to urge said sleeve toward the post in at least two generally radial directions, and wherein said sleeve comprises two sections each for engaging a circumferential portion of the post, said sections of said sleeve including means for aligning said sections together to embrace the post.
