Patent ID: 8246028

Claim:
A telescopingly adjustable clamp for securing an object to a support, the clamp comprising: an anchor rod having a first end portion, a second end portion and a longitudinal axis, the anchor rod being adapted for affixation to the object at the first end portion of the anchor rod and including a plurality of axially spaced, circumferentially extending grooves formed in the anchor rod, the grooves defining at least one barrier wall between adjacent grooves; a positioning member defining a receptacle sized and shaped to receive at least the second end portion of the anchor rod and to allow motion of the anchor rod relative to the positioning member in the receptacle, the positioning member comprising a positioning tab projecting into the receptacle and sized and shaped to be received in one of the grooves and retained in said one groove by the barrier wall; at least one of the positioning tab and the barrier wall being resiliently deflectable upon application of a release force along the longitudinal axis of the anchor rod for moving the positioning tab out of one of the grooves; a clamping member supported by the positioning member and extending generally radially outwardly from the longitudinal axis of the anchor rod, wherein relative movement of the anchor rod and the positioning member changes the distance between the clamping member and the first end portion of the anchor rod for clamping the object to the support; wherein the receptacle includes a capture section in which a second end of the anchor rod is captured, and wherein the capture section of the receptacle has a larger diameter than a support section of the receptacle, and wherein the anchor rod has a retainer projecting outwardly from the anchor rod to a radius that is larger than that of the support section.
