Abstract
Abstract A modular pipe system is provided for ease of securement to a ceiling or wall. The pipe system includes a back plate which is secured to the constructional surface, the back plate provided with a nesting surface for receiving a pipe and with longitudinal first complemental coupling means. The pipe is snap-fittably secured into said nesting surface. About the pipe is provided a first plate having longitudinal second coupling means proportioned for snap-fit engagement with the first coupling means such that the first plate will, in radial cross-section area between the interior of the front plate and the interior of the back plate, externally to said pipe. The front plate will be formed fire-resistance rated material such as a mineral-filled Noryl.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
147 words
A modular pipe system for securement to a constructional surface, comprising: (a) a back bracket having a back surface proportioned for securement to said constructional surface and having a front surface comprising resilient nestable rigidly securing means having a partially open face geometry in a direction opposite from said constructional surface, said back plate further comprising, along the edges thereof, longitudinal first complemental coupling means; (b) a pipe portioned for complemental coupling to said nesting means of said back plate; and (c) a front plate proportioned cross-section to said back plate and having, along the edges thereof, longitudinal second complemental coupling means proportioned for mating complemental engagement with said first complemental coupling means, whereby a modular pipe system may be formed by coupling said pipe to said nesting means and by mutually engaging said first and second complemental coupling means of said respective back and front plates.
Claim 2
Dependent Claim
147 words
A modular pipe system for securement to a constructional surface, comprising: (a) a back bracket having a back surface proportioned for securement to said constructional surface and having a front surface comprising resilient nestable rigidly securing means having a partially open face geometry in a direction opposite from said constructional surface, said back plate further comprising, along the edges thereof, longitudinal first complemental coupling means; (b) a pipe portioned for complemental coupling to said nesting means of said back plate; and (c) a front plate proportioned cross-section to said back plate and having, along the edges thereof, longitudinal second complemental coupling means proportioned for mating complemental engagement with said first complemental coupling means, whereby a modular pipe system may be formed by coupling said pipe to said nesting means and by mutually engaging said first and second complemental coupling means of said respective back and front plates.
Claim 3
Dependent Claim
37 words
The modular pipe system as recited in claim 1, further comprising insulation means disposed externally of said pipe and intermediately within the internal surfaces defined by said back and front plates after the mutual coupling engagement thereof.
Claim 4
Dependent Claim
41 words
The pipe system as recited in claim 1 in which: said complemental coupling of said pipe to said coupling means comprises a snap fit coupling; and said mating engagement between said front plate and said back plate comprises a snap-fit engagement.
Claim 5
Dependent Claim
69 words
A modular pipe system for securement to a constructional surface comprising: (a) a pipe hanger depending from said constructional surface; (b) a pipe secured to said pipe hanger at an end thereof opposite to the end secured to said constructional surface; and (c) a covering plate having, integrally formed therein, a nestable rigidly securing element proportioned for complemental engagement of said pipe about at least one cross-sectional semicircle thereof.
Claim 6
Dependent Claim
69 words
A modular pipe system for securement to a constructional surface comprising: (a) a pipe hanger depending from said constructional surface; (b) a pipe secured to said pipe hanger at an end thereof opposite to the end secured to said constructional surface; and (c) a covering plate having, integrally formed therein, a nestable rigidly securing element proportioned for complemental engagement of said pipe about at least one cross-sectional semicircle thereof.
Claim 7
Dependent Claim
32 words
The pipe system as recited in claim 4, further comprising insulating means disposed intermediately between the interior surface of said cover plate, facing said constructional surface, and the exterior of said pipe.
Claim 8
Dependent Claim
16 words
The pipe system as recited in claim 4 in which said constructional surface comprises a ceiling.
Claim 9
Dependent Claim
16 words
The pipe system as recited in claim 4 in which said constructional surface comprises a wall.
Claim 10
Dependent Claim
18 words
The pipe system as recited in claim 7 in which said wall comprises the intersection of two walls.
Claim 11
Dependent Claim
24 words
The pipe system as recited in claim 4 in which: said complemental engagement between said nesting element and said pipe comprises a snap-fit engagement.
Claim 12
Dependent Claim
152 words
A modular pipe system for securement to a constructional surface, comprising: (a) a back bracket having a back surface proportioned for securement to said constructional surface and having a front surface, said back plate further comprising along the edges thereof longitudinal first complemental coupling means; (b) a pipe proportioned for snap-fit coupling to said nesting means of said back plate; and (c) a front plate proportioned in cross-section to said back plate and having, along the edges thereof, longitudinal second complemental coupling means proportioned for mating snap-fit engagement with said first complemental coupling means, said front plate further comprising an integral resilient nesting means having a semi-circular open face geometry in a direction opposite from said constructional surface, whereby a modular pipe system may be formed by coupling said pipe to said nesting means and by mutually engaging said first and second complemental coupling means of said respective back and front plates.
Claim 13
Dependent Claim
152 words
A modular pipe system for securement to a constructional surface, comprising: (a) a back bracket having a back surface proportioned for securement to said constructional surface and having a front surface, said back plate further comprising along the edges thereof longitudinal first complemental coupling means; (b) a pipe proportioned for snap-fit coupling to said nesting means of said back plate; and (c) a front plate proportioned in cross-section to said back plate and having, along the edges thereof, longitudinal second complemental coupling means proportioned for mating snap-fit engagement with said first complemental coupling means, said front plate further comprising an integral resilient nesting means having a semi-circular open face geometry in a direction opposite from said constructional surface, whereby a modular pipe system may be formed by coupling said pipe to said nesting means and by mutually engaging said first and second complemental coupling means of said respective back and front plates.
