Abstract

A pipe clamp comprises a mounting post having a flexible arm extending laterally therefrom in a semi-circular arc. The arm defines with the mounting post an arcuate recess having spaced apart opposite ends between which different size pipe is selectively insertable into the recess. Opposed flexible fingers extend radially inwardly adjacent opposite ends of the recess. The fingers are axially angled between opposite sides of the clamp to facilitate bending of the fingers when contacted by the pipe during insertion of the pipe into the recess.

Claims

1. A pipe clamp for selectively supporting different size pipe, the clamp comprising a mounting post, and a flexible arm extending from the mounting post, the arm and the post defining a recess having spaced apart opposite ends between which the different size pipe is selectively insertable into the recess, and opposed flexible fingers extending radially inwardly from the recess, the fingers extend radially inwardly toward a center of the recess, wherein the fingers are axially inwardly inclined away from the arm and post and toward the center of the recess from one side of the clamp toward an opposite side of the clamp to form gaps between ends of the fingers and the arm and the post to facilitate bending of the fingers relative to the arm and the post when contacted by the pipe during insertion of the pipe into the recess for retaining the pipe in the recess;

wherein the mounting post has a bottom surface that extends below the pipe when fully inserted into the recess to provide a clearance space between the pipe and a mounting surface when the clamp is attached to the mounting surface with the bottom surface of the mounting post in engagement with the mounting surface;

wherein when a larger size pipe than the pipe is fully inserted into the recess, an outer diameter of the larger size pipe protrudes outwardly beyond the bottom surface of the mounting post, whereby when the clamp with the larger size pipe fully inserted into the recess is attached to the mounting surface with the bottom surface of the mounting post engaging the mounting surface, the outwardly protruding outer diameter of the large size pipe is clamped against the mounting surface; and

wherein the bottom surface of the mounting post has a tapered outer surface that is in substantial alignment with the outwardly protruding outer diameter of the larger size pipe when the larger size pipe is fully inserted into the recess, whereby both the tapered outer surface of the mounting post and the outwardly protruding outer diameter of the larger size pipe are clamped against the mounting surface when the clamp with the larger size pipe fully inserted into the recess is attached to the mounting surface.

2. The clamp of claim 1 further comprising a pair of circumferentially spaced, axially extending ribs on a radial inner surface of the recess intermediate the opposite ends thereof for cradling the pipe between the ribs when inserted into the recess.

3. The clamp of claim 1 further comprising a rib extending inwardly from a radial inner surface of the recess in closely spaced, substantially parallel relation to an inner side edge of each of the fingers for guiding the radial and axial inward bending of the fingers when contacted by the pipe during insertion of the pipe into the recess.

4. The clamp of claim 1 wherein the fingers are chamfered.

5. The clamp of claim 1 wherein an outermost end of the arm is in substantial alignment with the bottom surface of the mounting post when the clamp is in a fully relaxed condition and after the one size pipe is fully inserted into the recess, whereby when the clamp with the one size pipe fully inserted into the recess is attached to the mounting surface with the bottom surface of the mounting post engaging the mounting surface, the outermost end of the arm engages the mounting surface.

6. The clamp of claim 1 wherein a fastener hole extends through the mounting post and out the bottom surface for attaching the bottom surface of the mounting post to the mounting surface.

7. The clamp of claim 6 wherein another fastener hole extends through a portion of the arm opposite an opening between the spaced apart ends of the recess at an obtuse angle to a flat outer surface of the mounting post for attaching the flat outer surface of the mounting post to the mounting surface.

8. A pipe clamp for selectively supporting different size pipe, the clamp comprising a mounting post, and a flexible arm extending from the mounting post, the arm and the post defining a recess having spaced apart opposite ends between which the different size pipe is selectively insertable into the recess, opposed flexible fingers extending radially inwardly from the recess, the fingers extend radially inwardly toward a center of the recess, wherein the fingers are axially inwardly inclined away from the arm and post from one side of the clamp toward an opposite side of the clamp to form gaps between ends of the fingers and the arm and the post to facilitate inward bending of the fingers relative to the arm and the post when contacted by the pipe during insertion of the pipe into the recess for retaining the pipe in the recess, and ribs extending inwardly from a radial inner surface of the recess in closely spaced, substantially parallel relation to an inner side edge of each of the fingers for guiding the inward bending of the fingers when contacted by the pipe during insertion of the pipe into the recess;

wherein when a one size pipe is fully inserted into the recess, an outer diameter of the one size pipe protrudes outwardly beyond a bottom surface of the mounting post, whereby when the clamp with the one size pipe fully inserted into the recess is attached to a mounting surface with the bottom surface of the mounting post engaging the mounting surface, the outwardly protruding outer diameter of the one size pipe is clamped against the mounting surface; and

wherein the bottom surface of the mounting post has a tapered outer surface that is in substantial alignment with the outwardly protruding outer diameter of the larger size pipe when the larger size pipe is fully inserted into the recess, whereby both the tapered outer surface of the mounting post and the outwardly protruding outer diameter of the larger size pipe are clamped against the mounting surface when the clamp with the larger size pipe fully inserted into the recess is attached to the mounting surface.

9. The clamp of claim 8 wherein the fingers are chamfered.

10. The clamp of claim 8 wherein the bottom surface extends below the one size pipe when the one size pipe is fully inserted into the recess to provide a clearance space between the one size pipe and the mounting surface when the clamp is attached to the mounting surface with the bottom surface of the mounting post in engagement with the mounting surface.

11. The clamp of claim 8 wherein the a fastener hole extends through the mounting post and out the bottom surface for attaching the bottom surface of the mounting post to the mounting surface.

12. The clamp of claim 11 wherein another fastener hole extends through a portion of the arm opposite an opening between the spaced apart ends of the recess at an obtuse angle to a flat outer surface of the mounting post for attaching the flat outer surface of the mounting post to the mounting surface.

13. A pipe clamp for selectively supporting different size pipe, the clamp comprising a mounting post and a flexible arm extending from the mounting post, the arm and the mounting post defining a recess having spaced apart opposite ends between which the different size pipe is selectively insertable into the recess, wherein when one size pipe is fully inserted into the recess, an outer diameter of the one size pipe protrudes outwardly beyond the bottom surface of the mounting post, whereby when the clamp with the one size pipe fully inserted into the recess is attached to a mounting surface with the bottom surface of the mounting post engaging the mounting surface, the outwardly protruding outer diameter of the one size pipe is clamped against the mounting surface, and wherein the bottom surface of the mounting post has a tapered outer surface that is in substantial alignment with the outwardly protruding outer diameter of the one size pipe when the one size pipe is fully inserted into the recess, whereby both the tapered outer surface of the mounting post and the outwardly protruding outer diameter of the one size pipe are clamped against the mounting surface when the clamp with the one size pipe fully inserted into the recess is attached to the mounting surface.
