Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to a structure for installing a simple flush type Japanese-style toilet.

(Conventional installation structure of Japanese-style simple flush toilets) Simple flush toilets are installed in areas where public sewage facilities are underdeveloped, and are used to remove filth, etc. from inside the toilet bowl. It is configured to discharge a small amount of wash water to a pump-type toilet tank located underground.

FIG. 2 is a side sectional view showing how the simple flush Japanese-style toilet bowl 1 is installed. The floor surface of the toilet room shown in the figure is formed into a stepped portion (vertical surface of the stepped portion is shown by a broken line) with an appropriate height difference between the entrance side floor surface 8 and the floor surface 9 where the Japanese-style toilet bowl 1 is installed. The Japanese-style toilet 1 is of a so-called dual-use type, considering the convenience of both urination and urination. The Japanese-style toilet bowl 1 is fixed via a box-shaped construction frame 10 installed at the lower part of the installation floor surface 9. The configuration of the simple flush Japanese style toilet bowl 1 will be briefly explained below.

FIG. 3 is an enlarged sectional view showing the vicinity of the toilet bowl outlet 1b of the Japanese-style toilet bowl 1. A rotatable hemispherical valve body 2 is attached to the discharge port 1b. Further, a pedal rod 3a that projects toward the front side of the toilet bowl is connected to the valve body 2, as shown by a two-dot chain line. Therefore, when the pedal 3 at the tip of the pedal rod 3a is depressed, the valve body 2 rotates to open the discharge port 1b, and when the depression is released, the outlet returns to its original closed state. Further, as shown in FIG. 2, one end of a wire cable 4 is connected to the rotating base 3b of the pedal lever 3a, and the other end is a water conduit 7 that connects the low tank 6 (or high tank) and the Japanese-style toilet 1. It is connected to a flush valve 5 interposed therein. Therefore, when the pedal 3 is depressed as described above, the flush valve 5 is opened by the tensile force of the wire cable 4, and toilet bowl flushing water etc. are supplied from the low tank 6 to the toilet main body 1.

By the way, flushing or non-flushing Japanese style toilets are
In addition to being installed in a dual-use type as described above, it may also be installed as a type exclusively for urination (including female urination). In order to use the toilet exclusively for urination, a Japanese-style toilet is installed on the flat floor of the toilet room. However, the simple flush type Japanese-style toilet 1 as described above has a pedal rod 3a and a pedal 3 protruding from the front side thereof, and cannot be installed on a flat toilet room floor as a toilet-only type. Therefore, although not shown in the drawings, a configuration was adopted in which an operating handle was attached to the flush valve 5 (see FIG. 2). That is, when the operating handle is rotated, the wire cable 4 is pressed in the opposite direction, thereby rotating the valve body 2 that closes the toilet bowl outlet 1b. Of course, the flush valve 5 is opened by operating the operating handle, and the water in the low tank 6 is supplied to the Japanese-style toilet bowl 1. In this way, push the pedal lever 3a toward the front side of the toilet.
It has also become possible to prevent the pedal 3 from protruding. However, even if measures were taken to omit these pedal rods 3a and pedals 3, it was still not possible to construct a simple flush Japanese-style toilet 1 exclusively for urination.

FIG. 4 shows an exploded view of the conventional structure for fixing the Japanese-style toilet bowl 1 to the construction frame 10. Construction frame 1
A defecation pipe communicating with an underground toilet tank (not shown) is connected to the internal floor surface 10a of the toilet 0, with its end 15 protruding. Therefore, the construction frame 10
To fix the Japanese-style toilet 1 to the
A stool evacuation tube 14 attached to the buried part 1a under the floor of
into the tube end 15 of the defecation tube (see Figure 3). Then, the fixing metal fitting 12 is fitted into the mounting base 11 formed on the internal bottom surface 10a of the construction frame 10 (in the drawing, the fixing metal fitting 12 is shown hooked to the stool ejection tube 14 side), and the fixing metal fitting 12 is attached to the stool evacuation tube 14. make it hang.
And finally, the wing nut 13 of the fixing fitting 12
Tighten. In this way, the Japanese-style toilet 1 also serves as its entire fixation by fixing the toilet ejector tube 14. This is because since the Japanese-style toilet bowl 1 is made of ceramic, the dimensions of each product naturally vary, and a structure in which a part of the Japanese-style toilet bowl 1 is directly fixed cannot be adopted.

(Problems to be solved by the invention) In the conventional fixed structure, the Japanese-style toilet bowl 1 is installed in a dual-purpose manner, and the front decorative board 10b (third
(see figure) is removable. In other words, if a Japanese-style toilet is installed exclusively for urination, the entire circumference of the construction frame 10 will be buried under the floor of the toilet room, making it impossible to perform any operations regarding the fixing fittings 12.

The present invention was developed in view of the above-mentioned circumstances, and is a new installation structure (hereinafter referred to as the proposed installation structure) that makes it possible to construct a simple flush Japanese-style toilet for use only for urination. The purpose is to provide.

``Structure of the invention'' (Means for solving problems) The gist of the proposed installation structure is a box capable of storing the under-floor buried part of a simple flush Japanese-style toilet and the toilet ejector attached to the under-floor buried part. In a structure in which a construction frame is installed under the floor of the toilet room, and a Japanese-style toilet is installed in the construction frame, the construction frame is installed under the floor of the toilet room, and the pipe end of the defecation pipe that communicates with the toilet tank buried underground is connected to the inside bottom of the construction frame. A fastening tool such as a bolt is protruded from the upper edge to be inserted into a fastening hole drilled around the kinakakure part of the Japanese-style toilet, and the fastening tool can be moved along the length of the Japanese-style toilet. In addition, the fastening hole of the Japanese-style toilet bowl has an allowance diameter that allows it to swing horizontally relative to the fastener of the construction frame.

(Function) Fasteners such as bolts protruding from the upper edge of the construction frame are movable along the longitudinal direction of the Japanese-style toilet installed in the construction frame. Furthermore, the fastening hole of the Japanese-style toilet has a diameter that allows for horizontal swinging relative to the diameter of the fastener. In other words, the Japanese-style toilet installed in the construction frame can be adjusted and moved in the vertical and lateral directions with respect to the construction frame. Therefore, the Japanese-style toilet can be fixed based on the positional relationship between the defecation tube of the Japanese-style toilet and the end of the construction frame connected to each other. The moving direction of the fastener is set as the longitudinal direction of the Japanese-style toilet because the center-to-center distance from the center of the toilet ejector, which is attached to the buried part of the Japanese-style toilet under the floor, to the center of the fastening hole is long, and the dimensions are correspondingly longer. This is because the error may also become large.

(Example) The present invention will be described below based on drawings showing examples thereof.
