Abstract

A pipe support system comprises a pipe fitting and a pipe support. The pipe fitting is any standard fitting with the addition of two lugs added to the outside surface of the fitting so that they are diagonally opposite each other. The support has two arms joined together at the base and shaped so that they partially wrap around the fitting after installation. The inside surface of each arms is shaped to have a socket, the walls of which fit snugly against the respective lug after installation. The arms are fabricated of a stiff, elastic material so as to allow sufficient flexation of the arms during the installation of the fitting so that the fitting can pass between the tops ends of the arms without the support becoming permanently distorted.

Claims

1. An apparatus for supporting pipe such as PCV pipe or metal pipe, said apparatus comprising:

a standard pipe fitting

having an outer perimeter of its cross section and

configured with the addition of one or more mechanical protrusions wherein said protrusions are formed to have a shape of an arced segment of a slice of a cylindrical pipe somewhat larger than the fitting so that the outside diameter is the same as the inside diameter of the slice, the slice being taken perpendicular to the centerline of the larger cylindrical pipe and the inside diameter of the slice being equal to the outside diameter of the fitting and

a pipe support comprising

one or more arms,

each having an inner surface, and

each extending from a common base in a manner whereby the inner surface or surfaces of the arm or arms generally describe an area having a shape complimentary to said outer perimeter,

a gap between the end of the arm and the base or between the ends of the arms,

means for temporarily enlarging the gap in a manner whereby the gap is large enough for said pipe fitting to pass through the gap during installation,

means for reducing the enlarged gap, after installation, in a manner whereby said arm or arms fit snugly around said fitting in a manner whereby said fitting is held securely in place during use,

means for enlarging the gap, after installation, in a manner whereby the installed fitting may be removed from said support if said removal is intended, and

one or more recesses of sufficient number shape and position to snugly accommodate said protrusion or protrusions each said recess including an edge which engages an edge of its respective protrusion.

2. The apparatus of claim 1,

wherein said fitting is a standard round PCV pipe fitting;

wherein said protrusions are two in number and formed onto the outside of the fitting diagonally opposite each other, each formed to have a shape of an arced segment of a slice of a cylindrical pipe somewhat larger than the fitting so that the outside diameter is the same as the inside diameter of the slice, the slice being taken perpendicular to the center line of the larger cylindrical pipe and the inside diameter of the slice being equal to the outside diameter of the fitting;

wherein the arms are two in number and said arms extend in opposition to each other from the base and are shaped so that the inside surface of one arm is separated from the inside surface of the other arm by a cylindrical area which forms an arc greater than 180°

but less than 270°

, which area is complimentary in shape to the outside surface of the fitting in a manner whereby, after installation, said fitting is held snugly by said support;

wherein the arms are fabricated of a stiff, elastic material so as to allow sufficient flexation of the arms during installation of the fitting so that the flexed dimensional separation of the arms will accommodate the outside diameter of the fitting without the support becoming permanently distorted;

wherein the elasticity of the arms is choosen so that the force required for removal of the installed fitting from the support is greater than the force created in that direction by the natural loading of the piping system at the pipe support; and

wherein the inner surface of each arm is further shaped to have a recess which is complimentary in shape to the slice in a manner whereby each slice fits snugly into a recess.

3. A method of supporting pipe such as PCV pipe or metal pipe, said method comprising the steps of:

mounting a pipe support in a desired location,

said pipe support being configured to accept,

conform with and secure a pipe fitting,

said fitting comprising

a standard pipe fitting,

an outer perimeter of its cross-section, and

the addition of one or more mechanical protrusions wherein said protrusions are formed to have a shape of an arced segment of a slice of a cylindrical pipe somewhat larger than the fitting so that the outside diameter is the same as the inside diameter of the slice, the slice being taken perpendicular to the centerline of the larger cylindrical pipe and the inside diameter of the slice being equal to the outside diameter of the fitting,

said support comprising

one or more arms,

each having an inner surface, and

each extending from a common base in a manner whereby the inner surface or surfaces of the arm or arms generally describe an area having a shape complimentary to said outer perimeter,

a gap between the end of the arm and the base or between the ends of the arms,

means for temporarily enlarging the gap in a manner whereby the gap is large enough for said pipe fitting to pass through the gap during installation,

means for reducing the enlarged gap, after installation, in a manner whereby said arm or arms fit snugly around said fitting in a manner whereby said fitting is held securely in place during use,

means for enlarging the gap, after installation, in a manner whereby the installed fitting may be removed from said support, and

one or more recesses of sufficient number shape and position to snugly accommodate said protrusion or protrusions each said recess including an edge which engages an edge of its respective protrusion, and

installing said fitting into said support.
