Bolt Housing for Toilet Water Tank

Abstract

Toilet water tanks are mounted to the bowls with two bolts through two open holes. While rubber washers are used to seal the open bolt holes at the bottom of water tanks, water leaking is a century-old issue for many do-it-yourselfers. This invention designed a water-tight bolt housing to seal off the bolt hole. This invention eliminates the water leaking problem around water tank mounting bolts.

Description

BACKGROUND OF THE INVENTION

Two-piece toilet consists of a toilet bowl and a water tank. Water tank is traditionally mounted to the bowl by two bolts through two open holes at the bottom of a water tank. Rubber washers are used to seal off the bolt holes by the pressure applied by the bolts. However, water leakages around bolt holes occur very often due to improper installations and movements through the usages. For example, rocking motions caused by the back of a sitting person usually lead to loosening and tightening of the bolts, and thus result in temporary water leaking through the mounting holes. The water leaked can cause small damages such as water stains on the floor and big damages such as molds under the floors or inside walls, and water damages to the houses.

SUMMARY OF THE INVENTION

This invention designed a water-tight bolt housing for the bolt used for mounting the water tank to the toilet bowl. Because the housing is water-tight, water is sealed off from the bolt holes. Improper installations of the water tank will no longer result in water leakages around bolt holes. The movements of the water tank through the usages such as pushes by the back of a sitting person will not cause temporary leakages.

FIG. 3 shows the cross section of the water tank through the middle of the Bolt Housings.

DETAILED DESCRIPTION OF THE INVENTION

1. The Physical Structure

The invented water-tight Bolt Housing consists of units as follows:

(a) Locknut (FIG. 1)

• • Locknut locks and tightens the union to the bottom of the water tank.

(b) Rubber Washer (FIG. 1)

• • Rubber washer seals water when locknut tightens to the union.

(c) Male to Male Nipple Union (FIG. 1)

• • This union is the main part of the housing to host the bolt.

(d) Silicon Washer (FIG. 1)

• • Silicon washer seals off the water when tightened to the union.

(e) Flare Cap (FIG. 1)

• • Flare cap along with the silicon washer seal off the water from entering the bolt housing.

2. Operation of Water-Tight Bolt Housing

The main goal of this invented water-tight Bolt Housing is to seal off water from entering the housing and provide a space free of water for the mounting bolts:

• • (a) When locknut tightens the union with rubber washer to the bolt hole, water is seal off (FIG. 2).
  • (b) After the mounting bolts are used to mount the water tank, flare cap and silicon washer is screwed on to the top of the union. Thus, it seals off the water from entering the housing (FIG. 2).
  • (c) FIG. 3 illustrates that water is sealed off from entering the housing, thus providing a water free space for the mounting bolt. Therefore, improper installations of mounting bolts and movements through the usages will not cause any water leakage.
