Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for attaching a lower end portion of a bent water supply pipe for a urinal connecting a urinal body and a flush valve thereabove to a top portion of the urinal body.

[0002]

[Prior Art]

 Generally, the urinal body (1) and the flush valve (2) above it are located between the top horizontal surface of the body (1) and the lower end of the flush valve (2), as shown in FIG. The water supply pipe (3) having the gently bent obtuse-angled bends (3a) (3b) is arranged at an interval sufficient for easy attachment.

However, in some cases, due to the structure of the building and other factors, it may not be possible to provide a sufficient space between the urinal body (1) and the flush valve (2) as described above. In such a case, as shown in FIG. 3, the obtuse-angled bent portion of the water supply pipe is forcibly bent at a right angle using a pipe wrench, a monkey, etc., and the bent water supply having the right-angled bent portions (4a) (4b) is provided. Used a tube (4).

[0004]

[Problems to be solved by the device]

 However, in this bent water supply pipe (4), the forcibly bent right-angled bent portions (4a) and (4b) had bites inside the bent portions, which was not good in appearance. In addition, since the stud (12) for mounting the water supply pipe installed in the top insertion hole (7) of the urinal body (1) projects at a considerable height from the top horizontal surface of the urinal body (1), The space between the urinal body (1) and the flush valve (2) may be even smaller. In this case, the water supply pipe (4) had to be curved into an S-shape, and yet the installation of the bent water supply pipe was extremely difficult and sometimes impossible.

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

[0006]

[Means for Solving the Problems]

 The attachment device according to the present invention has been devised to achieve the above-mentioned object, and includes a cylindrical portion (6a) fitted in the top insertion hole (7) of the urinal body (1) and an upper end of the cylindrical portion (6a). A flange part (6b) attached to the top of the urinal body (1) and an O-ring (8) provided on the inner surface of the cylindrical part (6a). The lower end of the crank-shaped bent water supply pipe (5) in which the bent portions (5a) and (5b) are substantially perpendicular to each other is closely inserted.

The crank-shaped bent water supply pipe (5) in which the bent portions (5a) and (5b) are substantially right angles is composed of 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. The pipe and the lower vertical pipe having an inclined cut end face at the upper end are the inclined cut face of the upper vertical pipe and one inclined cut face of the intermediate horizontal pipe, and the other inclined cut face of the intermediate horizontal pipe and the lower vertical pipe. It is integrated by joining the inclined facets.

[0008] The inclined cut end faces of the upper vertical pipe, both inclined cut end faces of the intermediate horizontal pipe, and the inclined cut end faces of the lower vertical pipe are normally formed so as to be inclined at 45 ° with respect to the axis of each pipe. However, this angle is not limited, and is appropriately set so that the bent portions of the bent water supply pipe after joining form a substantially right angle.

The joining of the slanted facets is usually done by brazing, but is not limited to this.

The adhesion between the flange portion (6b) of the attachment member (6) and the top horizontal surface of the urinal body (1) is usually performed by adhering the packing (13) to the lower surface of the flange portion (6b) and then the packing (13 ) And the top horizontal surface with a double-sided adhesive tape interposed, but it may of course be done by other means.

【Example】

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

In FIG. 1, the crank that connects the urinal body (1) and the flush valve (2) at a small distance 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) that is bent like a circle is provided. The bent portions (5a) and (5b) of the bent water supply pipe (5) form a substantially right angle.

An insertion hole (7) is opened at the top of the urinal body (1), and a water supply pipe mounting member (6) is provided in the hole (7). The mounting member (6) includes a cylindrical part (6a) fitted in the insertion hole (7), and a flange part (6b) provided at the upper end of the cylindrical part and bonded to the top horizontal surface of the urinal body (1). , 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. There is. The packing (13) is bonded to the lower surface of the flange portion (6b) of the mounting member (6), and the packing (13) and the top horizontal surface are bonded by the double-sided adhesive tape (11).

The bent water supply pipe (5) having the right-angled bent portions (5a) (5b) is inclined at 45 ° with respect to the axis, and the upper vertical pipe having an inclined cut end face at the lower end and inclined at 45 ° with respect to the axis. It consists of an intermediate horizontal pipe having inclined end faces on both ends and a lower vertical pipe having an inclined end face inclined at 45 ° to the axis at the upper end. The inclined end face of the upper vertical pipe and one inclined end of the intermediate horizontal pipe. The end face and the other inclined cut end face of the intermediate horizontal pipe and the inclined cut end face of the lower vertical pipe are joined by brazing.

When arranging the bent water supply pipe (5) having the right-angled bent portions (5a) (5b) at a small distance between the top horizontal surface of the urinal body (1) and the lower end of the flush valve (2), For, cut the upper and lower vertical tubes in advance to an appropriate length. Then, fix the upper vertical pipe of the bent water supply pipe (5) to the lower end of the flush valve (2) with the nut (10) of the flush valve (2). On the other hand, insert the lower end of the bent water supply pipe (5) into the cylindrical part (6a) of the mounting member (6) provided in the top insertion hole (7) of the urinal body (1) to keep it watertight. Keep it.

[0016]

[Effect of the device]

 Since the bent water supply pipe for urinal according to the present invention is configured as described above, even if the gap between the top horizontal surface 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) can be connected without any problem, and compared with the conventional bent water supply pipe where the obtuse angled bent part of the bent water supply pipe is forcibly bent at a right angle using a pipe wrench, monkey, etc. It looks very nice in appearance.
