DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure for mounting a hand-washing spout pipe in a Western-style toilet having a hand-washing portion formed on the upper surface side of a low tank.

[Prior Art] A conventional example of this type will be described with reference to FIGS.

In FIGS. 5 and 6, a toilet seat 52 is installed on the upper surface side of the bowl of the toilet body 51, and a low tank 53 is erected on the toilet body 51 on the rear side of the toilet seat 52. A water supply pipe 54 is connected to the low tank 53 from the outside.
Water can be supplied into the low tank 53 via the.
Further, a lid member 55 having a hand-washing pot surface 55a is attached to the upper surface side of the low tank 53, and the spout pipe 5 capable of supplying hand-washing water toward the hand-washing pot surface 55a is attached to the lid member 55.
6 are erected.

The water supply pipe 54 is connected to the low tank 53 via a water stopper 57.
It is connected to the ball tap 58 inside. The water discharge pipe 56 is connected to the ball tap 58 via a connection pipe 58b. Reference numeral 58a indicates a float. The lower end of the water discharge pipe 56 is fixed to the lid member 55 with a nut 59. In the figure, 60 is an overflow pipe, 61 is a float valve, and 62 is a local cleaning device.

[Problems to be Solved by the Invention] Conventionally, in order to remove the lid member 55, it is necessary to loosen the nut 59 to separate the water discharge pipe 56 from the connection pipe 58b, which makes removal of the lid member 55 very difficult. It was For example, if the lid member 55 is forcibly lifted upward, the connecting pipe 58
b is broken. For this reason, the conventional water discharge pipe mounting structure has a problem that inspection of the inside of the low tank 53 is very troublesome.

[Means for Solving the Problems] The hand-washing water discharge pipe mounting structure for a low tank of the present invention is supported by a water discharge pipe erected on a hand-washing pot surface of the low tank and a mounting member at an upper edge of the low tank. The rising pipe has an upper end inserted into the water discharge pipe from below, and a bellows pipe connected to the lower end of the rising pipe and introducing water from a ball tap into the rising pipe. The mounting member has a holding portion at the upper edge of the raw tank and a support portion for the rising pipe.

In the present invention, the mounting member may further include a rubber material provided on the contact surface of the holding portion with the raw tank.

[Operation] In the structure of the present invention, since the rising pipe is inserted into the lower end portion of the water discharge pipe erected on the lid member, when removing the lid member from the raw tank, it is only necessary to lift the lid member. That is, when the lid member is lifted, the rising pipe remains held in the low tank via the mounting member, and only the lid member with the water discharge pipe is removed.

At this time, when a rubber material is provided on the mounting member, the frictional force between the mounting member and the raw tank is extremely large.
Therefore, when the lid member is lifted, even if an upward force is applied to the attachment member, the attachment member does not come off from the raw tank. Therefore, the work of removing the lid member can be performed extremely smoothly and easily.

In the present invention, even when the lid member is put on the raw tank, it is sufficient to place the lid member so as to be mounted from above, and this work is also easy. The rising pipe is connected to the ball tap through the bellows pipe, and the position of the mounting member can be freely changed. Therefore, since the installation position of the rising pipe can be freely adjusted, the position of the rising pipe can be freely adjusted according to the position of the water discharge pipe fixed to the lid member.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an assembly perspective view of an upper part of a low tank showing a structure of an embodiment, FIG. 2 is a side view of an essential part, FIG.
FIG. 4 is a plan view of the same.

On the upper surface of the lid member 55 of the low tank 53, the handwash spout pipe 1
Are fixed by a nut 59. Reference numeral 52 indicates a washer. A rubber packing 3 is attached to the lower end of the water discharge pipe 1.

The bell tap pipe 4 which can be expanded and contracted and bent is connected to the ball tap 58 disposed inside the low tank 53, and the tubular rising pipe 5 is integrally connected to the tip of the bellows pipe 4. Has been done. The bellows tube 4 and the rising tube 5 may be integrally formed, or separate pieces may be connected and integrated by using an adhesive or by fitting.

The rising pipe 5 is locked to the upper edge portion of the low tank 53 by a mounting member 6. The mounting member 6 includes a holding portion 6a at the upper edge of the low tank having a U-shaped side view, an arm portion 6b protruding from the holding portion 6a, and a C-shaped rising pipe grip provided at the tip of the arm portion 6b. The portion 6c is integrally formed of synthetic resin. A plurality (four in this embodiment) of rubber pieces 6d are bonded to the inner surfaces of the sandwiching portion 6a that face each other.

As shown in the figure, the holding portion 6a has a shape that narrows toward the opening on the lower end side. Further, in this embodiment, the rising pipe 5 has a shape in which the upper end thereof is obliquely cut.

The mounting member 6 is attached to the low tank 53 by being inserted into the edge portion of the low tank 53 from above so that the holding portion 6 a holds the upper edge of the low tank 53. The rising pipe 5 has a flange portion 5a at its lower portion, and the rising pipe 5 is held by the mounting member 6 by pushing between the flange portion 5a and the bellows pipe 4 into the grip portion 6c.

The attachment member 6 is attached to the raw tank 53 so that the position of the rising pipe 5 is aligned with the water discharge pipe 1. Startup pipe 5
May be attached to the attachment member 6 in advance, or the attachment member 6 may be attached after the attachment member 6 is attached to the low tank 53.

After attaching the rising pipe 5 to the low tank 53 as described above, by attaching the lid member 55 to the low tank 53 from above, the rising pipe 5 is inserted into the lower end portion of the water discharge pipe 1, and the rising pipe 5 is inserted. And the water discharge pipe 1 are integrated. The rising pipe 5 and the water discharge pipe 1 are watertightly joined by the sealing effect of the rubber packing 3 attached to the lower end of the water discharge pipe 1. Therefore, in order to attach the lid member 55 to the low tank 53, it suffices to attach the water discharge pipe 1 to the rising pipe 5, and when removing the lid member 55, simply lift the lid member 55 to automatically stand up. The water discharge pipe 1 is separated from the upper pipe 5.

In this embodiment, since the mounting member 6 is provided with the rubber piece 6d, the friction coefficient between the mounting member 6 and the low tank 53 is large, and the mounting member 6 can be easily pulled even if the mounting member 6 is pulled upward. Does not get out. Therefore, when the lid member 55 is lifted, only the lid member 55 having the water discharge pipe 1 can be lifted. Therefore, as in the conventional case, the rising pipe 5
Also, the bellows tube 4 is not pulled upward and broken.

In the present embodiment, the position of the mounting member 6 can be freely changed, and the bellows tube 4 can be freely expanded and contracted and bent, so that the rising tube can be installed at an arbitrary position. Therefore, the lid member 5
It is possible to attach the rising pipe 5 to various lid members 55 having different installation positions of the water discharge pipe 1 fixed to the pipe 5.

In the present embodiment, the tip (lower end) of the holding portion 6a of the mounting member 6 is
Since the mounting member 6 is recessed, the mounting member 6 has a strong force to clamp the upper edge of the low tank 53, and the mounting member 6 is very firmly supported by the low tank 53.

Further, in the illustrated embodiment, the tip of the rising pipe 5 is cut obliquely and has a sharp shape, so that the rising pipe 5 can be easily inserted into the water discharge pipe 1.

Although the mounting member 6 is separate from the rising pipe 5 in the above embodiment, the mounting member 6 and the rising pipe 5 may be integrally formed. Further, although the rubber piece is adopted in the above-mentioned embodiment, a rubber plate or an annular rubber member may be used. Such a rubber material can be provided in the sandwiching portion, for example, by bonding with an adhesive or by fitting it in a recess provided in the sandwiching portion. Furthermore, this rubber material can also be formed by applying and drying liquid rubber such as latex.

[Effect of the Invention] According to the low tank hand-washing spout mounting structure of the present invention, the lid member can be easily attached to and detached from the upper surface of the low tank by simply inserting or withdrawing the rising pipe at the lower end of the spout. Therefore, the work of removing the lid member can be performed very easily. In this case, by providing the mounting member with a rubber material, the mounting member supporting the rising pipe does not come off or move, and the above-mentioned work can be performed extremely smoothly. Further, according to the present invention, the position of the rising pipe can be freely adjusted and installed even if the lid member has a fixed position of the water discharge pipe.
