Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for attaching a lower end of a bent urinal for connecting a urinal body and a flush valve on the urinal to a top of the urinal body.

[0002]

2. Description of the Related Art Generally, a urinal body (1) and a flush valve (2) on the urinal body (1), as shown in FIG.
Between the top horizontal surface and the lower end of the flash valve (2)
Slowly bent obtuse bends near both ends (3a) (3b)
The water supply pipes (3) having the holes are arranged so as to allow easy attachment.

[0003] However, in some cases, due to the structure of the building and other factors, there is a case where a sufficient space as described above cannot be provided between the urinal body (1) and the flush valve (2). In such a case, as shown in FIG. 3, the obtuse bent portion of the water supply pipe is forcibly bent at a right angle using a pipe wrench, a monkey, or the like, and the bent water supply having the right-angled bent portions (4a) and (4b) is provided. tube
(4) was used.

[0004]

[Problem to be solved by the invention] However, in this bent water supply pipe (4), the right-angled bent parts (4a) and (4b) which are forcibly bent have a bite inside the bend, so that the appearance is good. It was not something. In addition, the stud (12) for installing the water supply pipe attached to the top insertion hole (7) of the urinal body (1) is
Since the projection protrudes from the horizontal plane at the top of (1) at a considerable height, the distance between the urinal body (1) and the flush valve (2) may be further reduced. In such a case, the water supply pipe (4) had to be curved in a substantially S-shape, and the installation of a bent water supply pipe was still extremely difficult and even impossible.

In view of the above, the object of the present invention is to provide a flush toilet (1) and a flush valve (2) even if the gap between the top horizontal surface of the urinal (1) and the lower end of the flush valve (2) is small. 2) A device for mounting a lower end of a bent water supply pipe for a urinal, which can be connected without any trouble.

[0006]

The mounting device according to the present invention has been devised to achieve the above object, and has a cylindrical portion (6a) fitted into a top insertion hole (7) of a urinal body (1).
A flange portion (6b) provided at the upper end of the cylindrical portion (6a) and bonded to a top horizontal surface of the urinal body (1); and a cylindrical portion (6a).
And an O-ring (8) provided on the inner surface of the
In (6), the lower end of a crank-shaped bent water supply pipe (5) in which each bent portion (5a) (5b) forms a substantially right angle is densely inserted.

A crank-shaped bent water supply pipe (5) in which each bent portion (5a) (5b) forms a substantially right angle has an upper vertical pipe having an inclined cut end face at a lower end and an intermediate horizontal pipe having an inclined cut end face at both ends. A pipe and a lower vertical pipe having an inclined cut end at the upper end, wherein the inclined cut end of the upper vertical pipe and one inclined cut end of the middle horizontal pipe, and the other inclined cut end of the intermediate horizontal pipe and the slope of the lower vertical pipe. They are integrated by joining the cut end faces.

[0008] The inclined cut end of the upper vertical pipe, the two inclined cut end of the middle horizontal pipe and the inclined cut end of the lower vertical pipe are usually
It is formed so as to be inclined at 45 ° with respect to the axis of each pipe, but this angle is not limited, and is appropriately set so that each bent portion of the bent water supply pipe after joining substantially forms a right angle. .

[0009] The joining of the inclined cut end faces is usually performed by brazing, but is not limited thereto.

The bonding between the flange portion (6b) of the mounting member (6) and the horizontal surface at the top of the urinal body (1) is usually performed using the flange portion (6).
The packing (13) is adhered to the lower surface of (b), and a double-sided adhesive tape is interposed between the packing (13) and the horizontal surface of the top. However, the packing may be performed by other means.

[0011]

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

In FIG. 1, a crank-shaped connection between the urinal body (1) and the flush valve (2) is provided at a small space between the top horizontal surface of the urinal body (1) and the lower end of the flush valve (2). A bent water supply pipe (5) is provided. The bent portions (5a) and (5b) of the bent water supply pipe (5) are substantially at right angles.

An insertion hole (7) is formed at the top of the urinal body (1), and a mounting member (6) for a water supply pipe is provided in the hole (7). The mounting member (6) includes a cylindrical portion (6a) fitted into the insertion hole (7), and a urinal body provided at an upper end of the cylindrical portion.
It comprises a flange portion (6b) adhered to the top horizontal surface of (1) and an O-ring (8) provided on the inner surface of the cylindrical portion. The O-ring (8) is fitted in a groove (9) formed in the inner surface of the cylindrical portion (6a) in the circumferential direction, and holds the lower end of the bent water supply pipe (5) in a watertight manner. . A packing (13) is adhered to the lower surface of the flange (6b) of the mounting member (6), and the packing (13) and the horizontal surface at the top are adhered by a double-sided adhesive tape (11).

A bent water supply pipe having right-angle bent portions (5a) (5b)
(5) is an upper vertical tube having at its lower end an inclined cut surface inclined at 45 ° to the axis, an intermediate horizontal tube having inclined inclined end surfaces at both ends inclined at 45 ° to the axis, and 45 ° to the axis.
A lower vertical pipe having an inclined cut end face inclined at an upper end, the inclined vertical cut end face of the upper vertical pipe, one inclined cut end face of the intermediate horizontal pipe, and the other inclined cut end face of the intermediate horizontal pipe and the lower vertical pipe. Are joined by brazing.

Bend water pipe having right-angle bends (5a) (5b)
In disposing (5) at a small interval between the top horizontal surface of the urinal body (1) and the lower end of the flush valve (2), the upper and lower vertical pipes are previously cut to an appropriate length. Then, flush the upper vertical pipe of the bent water pipe (5) with a flash valve.
Fix to the lower end of the flash valve (2) with the nut (10) of (2). On the other hand, a bent water supply pipe is attached to the cylindrical portion (6a) of the mounting member (6) provided in the top insertion hole (7) of the urinal body (1).
Insert the lower end of (5) and keep it watertight.

[0016]

[Effect of the invention] The bent water pipe for urinals according to the invention is
As described above, even if the gap between the horizontal surface at the top of the urinal body (1) and the lower end of the flush valve (2) is small, the urinal body (1) and the flush valve (2) do not interfere. It can be connected without any problem, and it has a much better external appearance than a conventional bent water supply pipe in which the obtuse bent part of the bent water supply pipe is forcibly bent at a right angle using a pipe wrench, a monkey or the like.
