Abstract
Abstract A pipe clamp for holding a pipe so as to isolate sound, prevent electrolysis and minimize heat transmission while avoiding pipe rupture and yet premitting pipe expansion and contraction can be formed of a single body of a resilient polymer material. This body includes a slotted cylindrical center section having ridges extending towards its interior and attaching flanges with ribbed lower surfaces, these flanges extending from the center section on opposite sides of the slot in the center section.

A pipe clamp formed as a unitary body of a resilient polymer material, said body including: a central cylindrical section having a slit therein, said slit extending the length of said section, a plurality of spaced, parallel, projecting flexible ridges located in the interior of said section so as to extend towards the axis of said section, said ridges extending the length of said section, the extremities of said ridges adjacent to the axis of said section being located equidistant from the axis of said section, the extremities of said ridges adjacent to the axis of said section having generally sharp edges and being capable of engaging the exterior of a pipe for minimal contact so as to hold such a pipe passing through said section, a pair of attaching flanges located on said center section adjacent to said slit, one of said flanges being located on one side of said slit and the other of said flanges being located on the other side of said slit, said flanges being aligned with one another and having bottom surfaces lying in the same plane, a plurality of flexible rib means for engaging a support for said pipe clamp so as to aid in holding said pipe clamp with respect to the support located on said bottom surfaces so as to extend therefrom and having generally sharp edges for minimal contact with said support, said ridges and ribs adapted to minimize heat and sound conduction and permit pipe expansion and contraction, said body being capable of being temporarily deformed so that said center section can be opened along said slit for the insertion of a pipe into said center section and being sufficiently resilient to resume its initial configuration after such insertion of a pipe, and said flanges each having a hole to accomodate a fastener located therein remote from said section, said holes extending through said flanges.
