Fluid overflow relief system

Abstract

An overflow relief system for a bath tub having an adapter having a first end attached to a drain opening for receiving fluid from the drain opening and a second end remote from the first end for connecting to a drain pipe, the adapter defining an adapter body between the first end and the second end of the adapter and defining a hollow interior surrounded by a sidewall defining an adapter body opening, a unitary conduit integrally formed to the tub having a first open end connected to an overflow opening and a second open end connected to the adapter body opening, the conduit providing a fluid passageway from the overflow opening to the adapter, and wherein the adapter forms a passageway for fluid to flow from the drain opening to the drain pipe and from the second end of the conduit to the drain pipe.

What is claimed is: 
     
         1 . An overflow relief system comprising:
 a tub having a base and a sidewall, said tub defining a drain opening formed in said base and an overflow opening formed in said sidewall;   an adapter having a first end attached to the drain opening for receiving fluid from said drain opening and a second end remote from said first end for connection to a drain pipe, said adapter defining an adapter body between said first end and said second end of said adapter, the adapter body defining a hollow interior surrounded by a sidewall, the sidewall of the adapter body defining an adapter body opening; and   a unitary conduit integrally formed to said tub, said conduit having a first open end connected to said overflow opening and a second open end connected to said adapter body opening, said conduit defining a fluid passageway from said overflow opening to said adapter;   wherein said adapter forms a passageway for fluid to flow from said drain opening to said drain pipe and for fluid to flow from said second end of said conduit to said drain pipe.   
     
     
         2 . The system of  claim 1  wherein the second end of the adapter fluidly connects the drain opening with the drain pipe. 
     
     
         3 . The system of  claim 2  wherein the second end is threaded. 
     
     
         4 . The system of  claim 1  wherein the adapter body opening is integrally formed with the second end of the conduit. 
     
     
         5 . The system of  claim 1  wherein the conduit is substantially elbow shaped. 
     
     
         6 . The system of  claim 1  wherein the conduit has a substantially oval cross-section. 
     
     
         7 . The system of  claim 1  wherein the connection between the first open end and the overflow opening is gasketed. 
     
     
         8 . The system of  claim 1  wherein the connection between the first end and the drain opening is gasketed. 
     
     
         9 . The system of  claim 1  wherein the integrally formed conduit and tub are coated with a protective coating. 
     
     
         10 . The system of  claim 9  wherein the protective coating comprises a fiberglass resin. 
     
     
         11 . A bath tub overflow relief system comprising:
 a bath tub having a fiberglass base and a fiberglass side wall, said bath tub defining an drain opening in said base and an overflow opening formed on said sidewall;   an adapter having a gasketed first end attached to the drain opening for receiving fluid from said drain opening and a second end remote from said first end for connection to a drain pipe, said second end including a threaded drain pipe connector, said adapter defining an adapter body between said first end and said second end of the adapter, said adapter body defining an adapter body opening; and   a corrugated elbow shaped unitary conduit having a flattened oval shaped cross-section integrally formed to said tub side wall, said conduit having a gasketed first open end connected to said overflow opening and a second end integrally connected to said adapter body opening, said conduit defining a fluid passageway from said overflow opening to said adapter,   wherein said adapter forms a passageway for fluid to flow from said drain opening to said drain pipe and for fluid to flow from said second end of the conduit to said drain pipe.   
     
     
         12 . A bath tub overflow system comprising:
 a bath tub overflow relief system comprising a bath tub having a fiberglass base and a fiberglass side wall, said bath tub defining an drain opening in said base and a generally rectangular overflow opening formed on said sidewall;   an adapter having a gasketed first end attached to the drain opening for receiving fluid from said drain opening and a second end remote from the first end for connection to a drain pipe, said adapter defining an adapter body between said first end and said second end of said adapter, said adapter body defining an adapter body opening; and   an elbow shaped conduit formed from a linear conduit piece and at least two elbow shaped fittings and having a flattened oval shaped cross-section integrally formed to said tub side wall, said conduit having a gasketed first open end connected to said overflow opening and a second end integrally connected to said adapter body opening, said conduit defining a fluid passageway from said overflow opening to said adapter,   wherein said adapter forms a passageway for fluid to flow from said drain opening to said drain pipe and for fluid to flow from said second end of said conduit to said drain pipe.
