Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a handle device for cleaning a toilet bowl.

[0002]

2. Description of the Related Art In a low tank for supplying flush water to a toilet bowl, a valve such as a float valve is provided at the bottom of the toilet tank, and the handle device pulls up the valve so that the water in the low tank is transferred to the toilet bowl. It is released toward.

FIG. 3 is a vertical sectional view showing a conventional example of a mounting structure of a handle device to a raw tank.

The handle device 1 comprises a column 2 having a flange 2a, a spindle 3 inserted in the column 2 and a handle 4 attached to the spindle 3.

The column 2 is fixed to the raw tank 5 by inserting the column 2 into the opening 6 provided in the raw tank 5 and tightening a nut 7 with a male screw provided on the outer peripheral surface of the column 2. That is, the edge portion of the opening 6 is sandwiched by the flange 2a and the nut 7.

A spindle 3 inserted in this column 2
Has one end bent in an L shape, and a linear body (not shown) such as a chain is hooked on the tip thereof. The other end of the spindle 3 projects from the column 12, and a handle 4 is attached to the tip of the column 12. By turning the handle 4, the float valve is pulled up via a linear body such as a chain, and the water in the low tank 5 is discharged to the toilet bowl.

The structure shown in FIG. 3 is usually adopted when the raw tank 5 is made of pottery. In recent years, a Western-style toilet bowl of a type referred to as a "console type" or the like having a low tank made of synthetic resin and a tank cover made of synthetic resin covering the low tank has been used in place of the low tank 5 made of ceramics. Is becoming

FIG. 4 is an exploded perspective view showing an example of such a Western-style toilet, in which a low tank 12 made of synthetic resin is installed on the upper rear surface of the Western-style toilet 11, and is covered with a tank cover 13 made of synthetic resin. The tank cover 13 includes a cover rear 14 that surrounds the rear side of the low tank 12 and the low tank 1.
Cover front 15 surrounding the front side of 2 and low tank 12
And a cover top 16 that covers the upper part of the. The handle device 1 is attached to the cover rear 14, and the toilet seat 17 and the toilet lid 18 are rotatably attached to the cover front 15.

The cover top 16 is provided with a hand-washing pot portion 19 and a hand-washing and spouting portion 20 for discharging water toward the hand-washing pot portion 19. An insert pipe 21 that is inserted into the hand-washing / water-discharging section 20 is attached to the cover rear 14, and the cover top 16 is attached to the cover rear 14.
When the cover front 15 is covered, the insertion pipe 21 is inserted into the hand-washing water discharge unit 20. This plug tube 21
A ball tap (not shown) provided on the raw tank 12 is connected via a tube 22.

The low tank 1 in the tank cover 13
On the lower side of 2, an apparatus such as a hot water washing device having washing nozzles 24, 25 for washing the buttocks of the human body with warm water, and a hot air blowing device 26 for drying the buttocks after washing with warm air. Is installed.

5 and 6 are a longitudinal sectional view and a perspective view showing the mounting structure of the handle device 1 to the cover rear 14. The handle device and its fixing structure itself are the same as in the case of FIG. 3, and the column 2 is inserted into the opening 28 provided in the cover rear 14 of the tank cover 13, the nut 7 is screwed into the column 2, and the nut 7 The handle device 1 is fixed to the cover rear 14 by sandwiching the edge of the opening 28 with the flange 2a. The raw tank 12 is provided with a U-shaped notch 29 for inserting the spindle 3.

[0012]

When the U-shaped cutout portion 29 is provided in the low tank 12 as shown in FIGS. 5 and 6, the water droplets that have jumped up inside the raw tank 12 pass through the cutout portion 29 and outside the low tank 12. Easy to jump out to.

In the conventional handle device mounting structure, the column 2 is fixed to the raw tank 12 by screwing the nut 7 into the column 2.
The nut 7 was turned many times, which was troublesome to mount.

The present invention solves such problems and provides a handle device mounting structure for cleaning a toilet bowl, which facilitates mounting of the handle device and prevents water droplets from splashing out of the low tank. The purpose is.

[0015]

The handle device mounting structure for toilet bowl of the present invention has a handle for covering a low tank for storing toilet flush water with a tank cover and discharging water from the low tank to the toilet bowl. A structure for mounting a device, wherein the handle device has a cylindrical column, a spindle inserted into the column, and a handle for turning the spindle, and a handle device mounting structure for toilet bowl cleaning. In the above, the raw tank and the tank cover are respectively provided with openings, the column of the handle device is inserted into the opening, and the flange provided on the column is brought into contact with the outer surface of the tank cover. A column movement blocking member is engaged between the stopper and the inner surface of the raw tank to attach the column to the raw tank and the tank cover. It is an.

In the mounting structure of such a handle device, since the row tank is provided with an opening for inserting a column, water droplets are extremely unlikely to splash out of the low tank as compared with the conventional example in which a U-shaped notch is provided. Becomes

Further, when the handle device is attached, it is only necessary to engage the column movement preventing member with the column, and the attaching work of the handle device is extremely easy.

In the present invention, it is preferable that the locking portion is a ridge provided on the outer peripheral surface of the column, and the column movement preventing member is a C-shaped member.

Further, in the present invention, it is preferable to provide means for preventing the raw tank and the tank cover from approaching each other at the place where the handle device is installed. By doing so, the handle device can be attached very firmly.

As this approach preventing means, a convex portion provided on at least one of the raw tank and the tank cover is preferable.
