Description

[Detailed Description of the Invention] The present invention mainly relates to a toilet joint for connecting a drain pipe to a Western-style toilet.

Generally, the connection between the toilet bowl opening and the drain pipe is made of rubber to maintain watertightness and absorb vibrations between the toilet bowl and the drain pipe.
A joint for a toilet is used, which is made of a soft elastic material such as synthetic rubber, and whose upper end is fitted onto the outer layer of the toilet opening on the bottom of the toilet, and whose lower end is inserted and fitted into a drain pipe.

In addition, several types of drain pipes with different inner diameters are usually used to connect, and for this reason, conventionally, several types of drain pipes with different outer diameters were formed according to the inner diameter of the drain pipes used. I needed to keep it.

In view of the above-mentioned current situation, the present invention allows the same joint to be used for drain pipes with different inner diameters with simple work, and also allows for easy connection work and maintains the same high watertightness when connecting any of the drain pipes. The purpose of this joint is to provide a joint for a toilet bowl that can be used for toilet bowls, and its gist is that the joint body is formed into a cylindrical shape using a soft elastic material such as rubber or synthetic rubber, and a trumpet-shaped joint is attached to the upper end of the joint body. In a toilet joint which is integrally provided with a toilet fitting part and in which a drain pipe can be freely fitted to the outer periphery from the lower end thereof, annular protrusions having a substantially semicircular cross section are arranged at appropriate intervals on the outer peripheral surface of the joint main body. The joint body is integrally formed with a folded cylindrical portion extending to the lower end of the joint body, and the folded cylindrical portion has an annular protrusion having a substantially semicircular cross section on its inner surface at a distance between the protrusions of the joint body. The joint for a toilet bowl is characterized in that the outer surface of the folded cylindrical portion at the position of the protrusion is formed in a corrugated shape that is annularly obstructed.

Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, numeral 1 indicates a joint body formed in a cylindrical shape.

The joint body is made of a soft elastic material such as rubber or synthetic rubber, and a fitting part 2 is integrally molded on the toilet bowl which is expanded in a trumpet shape at the upper end.

A curved part 3 having a substantially semicircular cross section is formed in the intermediate part of the fitting part 2 in the toilet bowl in an annular shape along the circumferential surface.

Further, annular protrusions 4 directed in the circumferential direction are integrally molded on the outer peripheral surface of the joint body 1, and the protrusions 4 have a substantially semicircular cross section and are provided in plural at regular intervals. .

Furthermore, a folded cylindrical portion 5 is integrally molded at the lower end of the joint body 1 in the direction of its extension.

This folded tube part 5 is formed thin so as to be folded back and overlapped on the outer peripheral surface of the joint body 1, and a protrusion 6 having a substantially semicircular cross section is formed on the inner circumferential surface of the folded cylinder part 5, which corresponds to the protrusion 4 on the outer circumference of the joint body. In correspondence with this, they are integrally molded at the same spacing.

The outer circumferential surface of the folded tube portion 5 is formed in a wavy shape with the outer side of the protrusion 6 being recessed.

When using the toilet bowl joint that can be constructed in this way and used for a small-diameter drain pipe 7a, the folded cylindrical part 5 is cut off as shown in FIG. Fit into place.

In addition, when used for a large diameter drain pipe 7b, the folded tube part 5 is folded back around the outer periphery of the joint body 1 as shown in FIG.
A drain pipe 7b is fitted around its outer periphery.

When folding it back, the ridge 6 of the folded tube 5 is folded back sufficiently so that it overlaps the ridge 4 of the joint body 1, and the drain pipe 7b is fitted around its outer periphery.

In the figure, 8 is the toilet main body, 9 is the toilet opening, 10 is the toilet stopper, and 11 is the toilet mounting screw.

The toilet joint of the present invention is constructed as described above, and has annular concave portions and annular convex portions each having a semicircular cross section formed on the outer surface of the cylindrical portion for fitting the drain pipe in a continuous and alternating manner. It has a bellows-like shape that fits into the unevenness of the tube, and is integrally equipped with a folded tube section that can be folded back and stacked on the outer surface of the tube section, allowing the - joint to connect drain pipes of several different diameters. It can be used, and the connection work can be done by folding back the folded tube part or press-fitting it into the drain pipe as it is, so no special process is required in addition to the conventional connection work using a joint. In addition, since the folded cylindrical part is formed into a bellows shape that corresponds to the outer surface of the cylindrical part, when it is folded back, it comes into close contact with the cylindrical part and does not shift. Like the cylindrical part itself, it has an annular uneven shape and maintains good watertightness.
