Flexible support bushing

A flexible support bushing adapted for encircling and clamping an element such as a pipe, cable or the like in position relative to a plate through which said element passes, said plate having a pre-determined thickness, said bushing comprising a unitary first member having a first annular portion with a first inner and a first outer diameter defining a pipe-gripping annnulus of substantially uniform thickness, said first annular portion being integrally formed with a second annular portion having a second inner diameter which is substantially equal to said first inner diameter and a second outer diameter larger than said first outer diameter, said second annular portion having two plate-engaging flanges which each extend radially outwardly an equal distance from said second annular portion and are spaced by a distance sufficient to accomodate said predetermined thickness of said plate, each said plate-engaging flange having a plate-engaging surface and a nonengaging surface, each said non-engaging surface having an annular groove formed therein to enhance flexibility, and a second member comprising an adjustable hose clamp encircling said pipe-gripping annulus and clamping said annulus snugly against the outer surface of said element with a uniform gripping force to prevent translational movement between said element and said plate.

A series of unitary, flexible support bushings each adapted for securing one of a variety of diameters of pipe, cable, or the like, in position relative to a plate having a standardized diameter aperture for receiving said bushings, said aperture having a predetermined periphery, each of said series of bushings comprising a first annular portion having a first inner and a first outer diameter, said first annular portion being integrally formed with a second annular portion having a second inner and a second outer diameter, each said first and second inner diameters being substantially equal to the outer diameter of the particular one of the variety of diameters of elements to be received therein, said second outer diameter of each bushing in said series being larger than its corresponding first outer diameter and substantially equal to said second outer diameter of each bushing in said series and, in turn, equal to the size of the standardized diameter aperture in said plate, each said second annular portion having two plate-engaging flanges of substantially equal diameter extending substantially radially therefrom and spaced by a distance which is at least equal to the thickness of the plate to engage said plate on each side thereof around the periphery of said standardized diameter aperture.
