Description
TITLE OF THE INVENTION
FLUID OVERFLOW RELIEF SYSTEM
FIELD OF THE INVENTION
This invention relates to a system and apparatus for relieving fluid, preferably water, overflow conditions in bathtubs.
3.0 BACKGROUND OF THE INVENTION
Water overflow prevention devices are universally used in bath tubs to prevent the overflow of water in the event the tub supply tap is left open while filling the bath.
Without such a device, the tub would overflow resulting in potentially extensive and costly water damage to the area surrounding the tub.
Currently-used overflow systems typically comprise multiple pieces of pipe and fittings that connect an overflow intake with the tub drain. The pipe and fittings are typically connected together using material-appropriate glue or threaded hardware to produce the overflow system.
In practice, the tub is installed during construction and the supply and drain lines are attached and tested for leaks. Afterwards, the various pipes and fittings are installed in place to produce the overflow system. However, by having the overflow system installed in this fashion, manual manipulation of the overflow pieces is required by the plumber and the multiple fittings introduces potential leak (failure) points as well as increasing installation costs.
Canadian patent application 2,248,822 teaches a bath tub water overflow system using a c-shaped trough that can be affixed to a bath tub to join an overflow inlet with a tub drain.
Canadian patent 2,109,081 teaches sink basin having a water overflow device comprising an integrated, multi-channeled conduit.
Canadian patent 2,171,383 teaches a bath tub water overflow system using a c-shaped trough joining the overflow inlet to the tub drain and adaptable to the shape of the tub wall and base.
Canadian patent 2,358,171 teaches removable bath tub system that can be installed in a shower to convert the shower to a bathtub and which possesses an overflow orifice connected to the tub drain via a channel.
Canadian patent 2,480,298 teaches a bath tub overflow assembly comprising multiple pieces that are assembled and attached after bath tub installation.
There remains a need for a bath tub overflow system that is efficient, durable and easy to install.

Preferably these fittings are connected using glue or adhesive.
In another embodiment, the conduit 30 can have a substantially oval cross-section. In this context, the term "substantially oval cross-section" means the shape is oval or elliptical and not circular. The conduit can be made from a polymer, preferably a polymer commonly used in the art.
In another embodiment, the adapter first end gasket 21 exists proximate the adapter first end 22 to ensure a watertight seal with the drain opcning.
With reference to Figures 1 and 4, a unitary conduit 30 has a first open end 32 attached to the overflow opening 15 in the tub sidewall 14 and a second open end 34 attached to the adapter body opening 28, providing a fluid passageway between the overflow opening 15 and the adapter 20. The unitary conduit 30 is integrally formed to the tub 10. In a preferred embodiment, the conduit second end 34 and the adapter body opening 28 are integrally formed.
This provides for a watertight connection between the adapter and the conduit and increases the strength and rigidity of the overflow relief system.

With reference to Figures 5, 6, 14, 15 and 20, in an alternate embodiment, the first open end 32 has a rectangular attachment 36 as shown in Figure 14 and a rectangular frame 36A as shown in Figure 20 attached to the rectangular overflow opening 16 in the tub sidewall 14. A decorative rectangular cap 37 as shown in Figure 15 covers the rectangular overflow opening 16. The conduit 30 has a second open end 38 attached to fittings 33A and 39 and the adapter body opening 28, providing a fluid passageway between the overflow opening 16 and the adapter 20.
The conduit 30 is integrally formed to the tub 10. In another embodiment, the conduit second end 38, fittings 33A and 39 and the adapter body opening 28 are connected with adhesive. This provides for a watertight connection between the adapter 20 and the conduit and increases the strength and rigidity of the overflow relief system. In another preferred embodiment, a first open end gasket 31 is located between the first open end 32 and the overflow opening 16 to provide a watertight seal between the first open end 32 and the overflow opening 16.
Preferably, the conduit 30 and fittings 33A and 39 have a generally flattened oval cross-section.
With reference to Figure 17 a metal strainer 44 is positioned in the drain opening 13 to prevent excess hair, objects or the like from entering the adapter 20.
In operation, the drain opening 13 is stoppered by a plug to allow water to enter and fill the tub 10. Once the water level reaches the overflow opening 15, water begins flowing into the overflow opening. Water then enters the conduit 30 through the first open end 32. The water travels the length of the unitary conduit 30 to the second end 34 of the conduit 30. Since the second end of 34 of the conduit 30 is connected to the adapter body opening 28, water flows through the adapter body opening 28 and into the hollow interior of the adapter 20. The water continues to flow through the adapter to the second end 24 of the adapter. The water then flows into the connected drainpipe.
In operation of an alternate embodiment, the drain opening 13 is stoppered by a plug to allow water to enter and fill the tub. Once the water level reaches the rectangular overflow opening 16, water begins flowing into the overflow opening. Water then enters the conduit 30 through the

Water then flows through the adapter body opening 28 and into the hollow interior 52 of the adapter 20. The water continues to flow through the adapter to the second end 24 of the adapter. The water then flows into the connected drainpipe.
Removal of the plug from the drain opening 13 allows water to flow through the drain opening 13. Water then flows from the drain opening into the hollow interior of the adapter 20. The water continues to flow through the adapter to the second end 24 of the adapter. The water then flows into the connected drainpipe. Where water is contemporaneously flowing from the overflow opening 15 or the rectangular overflow opening 16 through the conduit 30, water from the drain opening 13 and from the overflow opening 15 or the rectangular overflow opening 16 will mix in the hollow interior 52 of the adapter 20. Through this operation, the water in tub 10 does not overflow the tub and cause water damage to the area surrounding the tub.
The construction of the system as a unitary apparatus comprising a bathtub and an overflow relief conduit provides an efficient system. The fiberglass protective layer covering the bathtub and the conduit helps to avoid damage to the system during transport.
