Description

Detailed Description of the Invention The present invention provides a toilet bowl, a low tank, and a low tank cover that are integrally attached, and a handle for operating a float valve for supplying flush water to the toilet bowl that is attached to the low tank. This article relates to (1) a low-tank closed type toilet that is divided into a main body and a handle lever attached to a low-tank cover.

FIG. 1 is an exploded perspective view showing a conventional low tank closed type toilet bowl 1, and FIG. 2 is a partial sectional view showing how the low tank 2 and toilet bowl 3 are attached. As shown in the figure, the conventional low tank closed type toilet bowl 1 has a pedestal 4 formed on the upper surface of the rear side of the toilet bowl 3, and the low tank 2 is connected and fixed to the pedestal 4 with bolts 5 or the like. A pole tap 6 is attached to the upper part of the left side wall of the low tank 2 so that one end thereof penetrates to the outside, and is connected to a water supply pipe 8 through a water supply pipe 7. Furthermore, a handle 9 for operating a float valve, which is integrally formed with a handle body 9a and a handle lever 9b, is attached to the upper part of the right side wall of the low tank 2, and is connected to a float valve 10 fixed to the bottom of the low tank 2. .

However, the connection between the low tank 1 and the toilet bowl 2 is
First, insert the bolt 5 into the bolt hole provided on the bottom of the low tank 2.
, and fix it with a nut 11 , insert the bolt 5 into the bolt hole of the pedestal 4 , and tighten the nut 1 from the bottom side of the pedestal 4 .
This fixing method of tightening nuts from the bottom side of the pedestal 4, which had to be done by screwing 2 together (2), requires that the work be done in an awkward position in a toilet room where space is limited. Otherwise, uneven tightening may occur.

As a result, the sealing function of the gasket 13 disposed between the low tank 2 and the toilet bowl 3 is lost, resulting in the problem of water leakage.

Furthermore, since the connecting part between the low tank 2 and the toilet bowl 3 is exposed to the outside, and the bottom surface of the low tank 2 and the top surface of the pedestal 4 are not in close contact with each other, there is no sense of unity between the two, which tends to result in a lack of design. Ta.

Furthermore, between the pole tap 6 and the water supply pipe 8,
The water supply pipe 7 for connecting these parts is exposed, which has a disadvantage in that it looks unsightly.

The present invention improves and eliminates the above-mentioned drawbacks of conventional low-tank closed toilet bowls, and includes a low-tank and a low-tank cover that covers the low-tank attached to the installation part formed on the upper surface of the rear side of the toilet. Attach the handle body (3) for operating the float valve to the top of the side wall, and attach the handle lever rotatably to the position corresponding to the above handle body attachment part of the low tank cover, and connect the other end of the above handle body to the handle lever. By connecting the two via serrations, etc., the low tank and attached parts such as the water supply pipe are not exposed to the outside, and the toilet bowl and the low tank cover create a sense of unity. It is something to do.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 3 is an exploded perspective view of the second low-tank closed toilet bowl 14 according to the present invention, FIG. 4 is a perspective view of the assembled low-tank closed toilet bowl 14 seen from the upper left side, and FIG. 5 is a perspective view of the low tank closed toilet bowl 14 seen from the upper right side. FIG. As shown in FIG. 3, an installation portion 18 for mounting and fixing a low tank 16 and a low tank cover 17 is formed on the upper surface of the rear side of the toilet bowl 15 of the low tank closed type toilet bowl 14. The installation section 18 has a pedestal 19 for installing the low tank 16 and a pedestal 20 for installing the metal J, and also has a standing wall 21 (4) around the periphery.

To install the low tank 16, as shown in FIG. 6, a bolt 23 having a double terminal structure is inserted into the bolt hole 19a of the pedestal 19 from the bottom side of the pedestal 19, and then fixed with a nut 24. Then, the low tank 16 is connected via the packing 25.
is placed on the pedestal 19, and the bolt 26 is screwed into the screw hole 27 of the bolt 23 from the inner side of the low tank 16.If the installation is from the inner side of the low tank 16, the work is simple. It is not an unreasonable posture and it is easy.

After attaching the low tank 16, a ball tap 28 is attached to the upper left side wall of the tank 16, and a handle body 29 for operating the float valve is rotatably attached to the upper right side wall. The pole tap 28 is installed using a nut 53 from the outer wall side of the low tank 16, and a connecting elbow 54 is attached to the inlet side thereof. As shown in FIG. 7, the connecting elbow 55 of the water supply pipe 22, which is attached to penetrate the upright wall 21 and face the inside thereof, and the inlet side of the ball tap 28 are connected via union nuts 56 and 57. Connect with the water supply pipe 30 (5), and install the handle body 29 at the 10th FI.
! As shown in J, insert the threaded portion 29a of the handle body 29 into the through hole 58 from the outside of the low tank 16, and then tighten the nut 5.
Conclusion at 9. Then, one end side of the handle body 29 and the float valve 31 are connected by a chain 32 or the like.

After that, the low tank cover 17 is fixed.

To fix this low tank cover 17, first, as shown in FIG. 3 and FIG.
Place the bolt 35 into the bolt hole 34 of the pedestal 19.20.
By inserting it through and tightening it with the nut 36,
The metal fittings 33 are fixed. This metal fitting 33 has a screw hole 40 for attaching the low tank cover, which is located above the upper end surface 21a of the standing wall 21 after being attached. Then, as shown in FIGS. 3 and 9, a flat metal fitting 39 is fixed to the inner surface of the upright wall 21 by inserting bolts 38 into through holes 37 formed at the left and right rear sides of the upright wall 21. Like the metal fitting 33 described above, this flat metal fitting 39 also has a screw hole 41 for attaching the low tank cover located above the upper end surface 21a of the upright wall 21 after installation.

(6) After the attachment of the metal fittings 33 and 39 is completed in this manner, the low tank cover 17 that covers the low tank 16 is placed on the upper end surface 21a of the upright wall 21 with its end surfaces butted against each other. Through holes 42 and 43 are drilled in the front and rear positions near the lower end of the left and right side walls of the low tank 16.
45, and attach these ports) 44.45 to the metal fitting 3 above.

4.45 and the through hole 42.43.

Next, as shown in FIG. 10, a bundle lever 46 for operating the float valve is rotatably attached to the upper right side of the low tank cover 17. The handle lever 46 is installed by inserting the guide member 61 into a through hole 60 bored at a position corresponding to the attachment part of the handle body 29 of the low tank 16.
is inserted and fastened with a nut 62. Then, the handle lever 46 is inserted into the guide member 61, and the tip side of the handle lever 46 and the handle body 29 are connected by the serration shaft 47, the serration (7), the silane groove 48, etc. Finally, the handle lever 46 and the handle body 29 are fixed with the fixing member 49, and the screw hole 52 of the handle lever 46 and the member 49 are covered with the lid member 50.

By the way, the conventional flow I/valve operating handle 9 shown in FIG. 1 has a handle body 9a and a handle lever 9b.
are integrally formed. With such an integrally formed handle 9, it is practically impossible to attach it to the low tank closed type toilet bowl 14 which consists of the toilet bowl 15, the low tank 16, and the low tank cover 17. The reason for this is that after the low tank cover 17 is attached, one end side of the handle body 9a and the float valve 31 cannot be connected with the chain 32 or the like inside the low tank 16.

If the low tank closed type toilet bowl 14 is constructed as in the present invention, the work of installing the low tank 16 is as follows.
This can be done from above inside the tank, and the low tank cover 1
The installation work No. 7 can be performed from the left and right sides. Therefore, even if the toilet is small, it is easy to work from an area with plenty of space (8). Moreover, in this low tank closed type toilet bowl 14, since the low tank cover 17 covers the low tank 16, the water supply pipe 30 etc. are not directly exposed to the outside, resulting in a very attractive appearance with excellent design. It's good. Furthermore, the attachment surfaces of the low tank cover 17 and the toilet bowl 15 are in perfect contact with each other by abutting their ends, creating a sense of unity and providing a calm and dignified feel.

In the above embodiment, the case where there is no hand washing is described, but the technology of the present invention is of course applicable even to a case where hand washing is provided.

As explained above, the technology of the present invention can be applied to toilet bowls.

A low tank closed toilet bowl consisting of a low tank and a low tank cover has a handle for operating the float valve.
Since it consists of a handle body that is attached to the low tank and a handle lever that is attached to the low tank cover, the installation work is easy. In addition, with this low tank closed toilet bowl, the low tank can be fixed from the inner surface of the tank (9), and the low tank cover can be fixed from the side of the cover, so it can be used in narrow toilets. These tasks can be performed relatively easily even indoors. In addition, the low tank cover prevents accessory parts such as water supply pipes from being exposed to the outside, giving it a good appearance.Furthermore, the toilet bowl and low tank cover are attached closely with their ends butting, creating a sense of one body. The result is a calm drink with a profound feel.
