Abstract

A pipe coupling support having a substantially rigid body with an inner surface formed to mate with at least a portion of the exterior surface of a pipe coupling installed on pipe. In many cases, the exterior surface of the installed pipe coupling will be non-cylindrical. For example, when pipes of differing diameters or pipes manufactured from different materials must be joined with commonly available pliable couplings. In this instance the inner surface of the body of the pipe coupling support may be formed to mate with a majority of or substantially the entire exterior surface of the installed pipe coupling.

Claims

1. A pipe coupling support in combination with an installed pipe coupling, the installed pipe coupling connecting a first pipe having a first exterior diameter and a second pipe having a second exterior diameter different from the first exterior diameter, the installed pipe coupling including a pliable body having a first portion receiving the first pipe, a second portion receiving the second pipe, and at least one clamping apparatus securing the pliable body to the first pipe and the second pipe, the pipe coupling support comprising:

a rigid body having;

a first opening having a first size, the first opening operable to receive the first pipe with the first exterior diameter; and

a second opening having a second size such that the second opening is operable to receive the second portion of the installed pipe coupling when the second pipe with the second exterior diameter is inserted in to the pliable body of the installed pipe coupler;

wherein the second opening is larger than the first opening thereby allowing the rigid body to be slipped over the pipe coupling after the pipe coupling has been installed on the first pipe and second pipe, wherein the clamping apparatus further comprises a first hose clamp comprising a first worm drive bolt, the first hose clamp compressing the first portion of the pliable body against the first exterior diameter of the first pipe and the rigid body of the pipe coupling support covers the first portion of the pliable body, the first hose clamp and first worm drive bolt when the pipe coupler support is installed on the installed pipe coupling.

2. The pipe coupling support of claim 1, wherein the pipe coupling support further comprises a recess in the rigid body positioned to receive a protruding structure from the installed pipe coupling.

3. The pipe coupling support of claim 2, wherein the at least one clamping apparatus comprises a second hose clamp comprising a second worm drive bolt, the second hose clamp compressing the second portion of the pliable body against the second exterior diameter and the recess is shaped to receive the worm drive bolt when the pipe coupling support is installed on the installed pipe coupling.

4. The pipe coupling support of claim 3, wherein the first opening and the second opening are concentric openings, thereby aligning the centers of the first pipe and the second pipe when the pipe coupling support is installed.

5. The pipe coupling support of claim 1, wherein the rigid body of the pipe coupling support covers the first portion and the second portion of the pliable body when the pipe coupling support is fitted on the installed pipe coupling.

6. The pipe coupling support of claim 1, wherein when the pipe coupling support is fitted on the installed pipe coupling the pipe coupling support prevents the pliable body from flexing by stabilizing the fist pipe and the second pipe with the rigid body, the first pipe being stabilized through direct contact with the rigid body and the second pipe being stabilized through the rigid body'"'"'s contact with the second portion of the installed pipe coupling.

7. The pipe coupling support of claim 1, further comprising an inner support.

8. The pipe coupling support of claim 7, wherein the inner support is operatively positioned between an inner surface of the rigid body and a portion of an exterior surface of the installed pipe coupling.

9. The pipe coupling support of claim 8, wherein the inner surface is sloped to transition an interior diameter between the first size of the first opening and the second size of the second opening.

10. The pipe coupling support of claim 1, further comprising a support sleeve operatively positioned between the inner surface of the rigid body and the installed pipe coupling.

11. The pipe coupling support of claim 10, wherein the support sleeve defines one or more recesses.

12. The pipe coupling support of claim 1, further comprising a pliable inner surface sized to mate with an outer surface of the first pipe.
