Abstract

A clamp for mounting pipes on a support, including a band that encircles the pipe and has a pair of end tabs that can be held together, and a mount strap fixed to the band and having mounting holes whose axes are out of line with the tabs. An elastomeric cushion on the band has a pair of radially extending end ridges formed to curl out and a middle ridge of smaller height and located between the end ridges.

Claims

1. A pipe mounting clamp comprising:

a band for encircling a pipe, said band having a pair of tab portions fastenable to each other to tighten the band on the pipe; and

a cushion of resilient material covering the radially inner surface of the band to contact and encircle the pipe, said cushion having a pair of radially-inwardly extending end ridges at the axially opposite ends of the cushion and having a middle ridge located between said end ridges, each of said end ridges having a height which is at least 50 percent greater than the height of said middle ridge, whereby the middle ridge does not contact a pipe until the end ridges have been severely deformed.

2. The clamp described in claim 1 including:

a clamp support, said band being mounted on said support; and

a pipe, said band and cushion surrounding said pipe to tend to hold it at a predetermined orientation with respect to said clamp support, but said pipe being free to tilt with respect to said predetermined orientation;

said end ridges being angled to extend away from said middle ridge and said cushion being tightened sufficiently on said pipe so that the middle ridge contacts the pipe while the end ridges are deformed away from the middle ridge, whereby when the pipe tilts it tends to tilt about the middle ridge as a fulcrum so that both end ridges tend to remain in contact with the pipe.

3. The clamp described in claim 1 wherein:

each of said end ridges has an outer surface whose top portion has a bead that extends away from the middle ridge.
