Abstract
Abstract A pipe-supporting device adapted to receive and support an exposed pipe on a roof has a substantially flat bottom for resting on the roof and an upwardly tapered structure secured on and rising from the base to provide a pipe positioning and supporting structure which substantially equally distributes the weight of the supported pipe over the area of the base in contact with the roof. The pipe positioning and supporting structure has a pocket for positioning a pipe therein and the pipe is supported in the pocket by at least one roller positioned in at least one receiving trough. As the pipe expands or contracts, it rides on the roller which rotates within the trough.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
A pipe-supporting device adapted to receive and support an exposed pipe on a roof, said device comprising a base having a substantially flat bottom for resting on the roof; upwardly tapered structure secured on and rising from said base to provide a pipe positioning and supporting structure having a pocket for positioning a pipe therein; trough means within the pocket for receiving roller means therein; roller means adapted to fit into the trough means and to rotate therein and adapted to have a pipe rest thereon to be supported above the base, said pipe positioning and supporting structure having lower ends forming a symmetrical periphery at the base which substantially evenly distributes the pipe load on the roller means over the base and on the roof.
Claim 2
Dependent Claim
126 words
A pipe-supporting device adapted to receive and support an exposed pipe on a roof, said device comprising a base having a substantially flat bottom for resting on the roof; upwardly tapered structure secured on and rising from said base to provide a pipe positioning and supporting structure having a pocket for positioning a pipe therein; trough means within the pocket for receiving roller means therein; roller means adapted to fit into the trough means and to rotate therein and adapted to have a pipe rest thereon to be supported above the base, said pipe positioning and supporting structure having lower ends forming a symmetrical periphery at the base which substantially evenly distributes the pipe load on the roller means over the base and on the roof.
Claim 3
Dependent Claim
15 words
A pipe-supporting device according to claim 1, wherein the pipe receiving pocket is downwardly convergent.
Claim 4
Dependent Claim
45 words
A pipe-supporting device according to claim 2, wherein the roller means extends across the bottom of the downwardly convergent pocket forming a flat bottom therefore, and the roller means is adapted to receive and support a pipe to be supported by one point contact thereon.
Claim 5
Dependent Claim
26 words
A pipe-supporting device according to claim 3, wherein the downwardly convergent pocket is formed by two arcuate sides which meet at the bottom of the pocket.
Claim 6
Dependent Claim
34 words
A pipe-supporting device according to claim 4, wherein the device, except for the roller means, is integrally molded from a polyvinylchloride plastic material and the roller means is made of a Teflon plastic material.
Claim 7
Dependent Claim
15 words
A pipe-supporting device according to claim 4, wherein the trough means is a V-shaped grove.
Claim 8
Dependent Claim
56 words
A pipe-supporting device according to claim 2, wherein the downwardly convergent pocket forms a substantially V recess having divergent line contacts for receiving and supporting the pipe, and wherein the roller means includes a roller along each of the divergent line contacts so that the pipe is supported along such divergent line contacts by the rollers.
Claim 9
Dependent Claim
14 words
A pipe-supporting device according to claim 7, wherein the trough means are semicircular grooves.
Claim 10
Dependent Claim
34 words
A pipe-supporting device according to claim 7, wherein the device, except for the roller means, is integrally molded from a polyvinylchloride plastic material and the roller means is made of a Teflon plastic material.
Claim 11
Dependent Claim
32 words
A pipe-supporting device according to claim 1, wherein the base includes at least one channel formed in the bottom of the base to provide for drainage of water from under the device.
