Description

[Detailed Description of the Invention] This invention relates to a connection device for pipes such as water pipes and drain pipes in wash basins and the like.

Conventionally, construction work has been carried out to penetrate the backboard of the wash basin and connect piping such as water pipes to the end of the water pipes extending from the building frame on site. Because each pipe is different, it was not possible to drill a pipe insertion hole in the back plate of the washbasin in advance, so the holes had to be aligned on site. This on-site drilling work has the drawback of being extremely troublesome and time-consuming.

Therefore, Special Publication No. 56-6766, Special Publication No. 56-6766,
As seen in Publication No. 6767 or Japanese Patent Publication No. 16647/1983, holes for punching are formed in the back plate of the washstand with thin sections or discontinuous slits, and the holes can be opened on site. A proposal was made to make the work easier.

However, in the case of these items, although the opening work is facilitated by cutting the back plate along the thin wall section or slit, it is extremely difficult to confirm the piping position on the building frame side through the thin slit. At the same time, since the entire washstand must be moved when cutting, there is an inconvenience in that the washstand must be moved each time the pipes are aligned, cut, or installed. Particularly in the case of thin-walled pipes in which punched holes are formed, the position of the pipes on the building frame cannot be visually recognized from the sink side, making alignment extremely difficult.

This invention was devised to eliminate the above-mentioned drawbacks found in conventional pipe connection devices for washstands, etc., and will be described in detail below with reference to the drawings.

This invention will be described below regarding the connection of a water pipe in a washstand, but the invention is not limited thereto. It can be similarly applied to other furniture such as sinks and gas cabinets, and is also suitable for connecting not only water pipes but also gas pipes and drain pipes.

In the figure, reference numeral 1 denotes a rectangular box-shaped washstand with a water tank 2 in the center of the upper part. Connect to the end of the water pipe 7 extending from the water pipe 7.

A large-diameter pipe port 8 is previously opened in the back plate 5, and the pipe port plate 9 is removably fixed to the inner surface of the back plate 5 by closing the opening 8. The pipe port 8 has a sufficient size to cover substantially all the pipe positions of the water pipes, which differ from building to building, and there is no need to re-open the pipe port 8 in accordance with the pipe position.

The pipe port plate 9 is preferably a rectangular plate having a size sufficient to close the large diameter pipe port 8, and is detachably fixed to the inner surface of the back plate 5 with screws or the like. A large number of small circular holes 10 are bored through substantially the entire surface of the pipe port plate 9. The small circular holes 10 are regularly arranged at regular intervals, and preferably the small circular holes 10 are formed at the intersections 12 of a plurality of parallel diagonal lines 11 of 60° and 120° spaced at regular intervals. Ru. When the small circular holes 10 are arranged along the intersections 12 of the diagonal lines 11, the small circular holes 10 can be connected in a straight line and then cut to open the hexagonal pipe insertion hole 13. This has the advantage that the pipe insertion hole 13 can be formed in an attractive manner, and the opening work is easy.

When actually connecting the piping, use the piping port 8 on the back plate 5.
Install the washbasin 1 facing the end of the water pipe 7 on the building frame side, visually check the position of the water pipe 7 through the small circular hole 10, and mark the pipe position on the pipe opening plate 9 in black or the like. do. Thereafter, only the pipe port plate 9 is removed and cut along the small circular hole 10 to cut out the pipe insertion hole 13. After the connecting pipe 4 is inserted into the pipe insertion hole 13 and the connecting pipe 4 and the water pipe 7 are connected, the pipe port plate 9 is fixed to the back plate 5.

Thus, according to this invention, a large diameter pipe port 8 is drilled in the back plate 5 of furniture such as a washstand, and the pipe port 8 is opened.
A pipe port plate 9 that closes the pipe port 8 is removably fixed to the inner surface of the back plate 5 while blocking the pipe port 8, and a large number of small circular holes 10 are provided in the pipe port plate 9 over almost the entire surface. The small circular holes 10 are arranged in parallel at equal intervals.
Since it is formed at the intersection of multiple diagonal lines 11 of 60° and 120°, the pipe position can be visually confirmed through the small circular hole 10, and the pipe insertion hole 13 is drilled in the pipe port plate 9 while determining the accurate position. In addition, when opening the pipe insertion hole 13, only the pipe port plate 9 can be removed, and there is no need to move the washbasin 1, resulting in good workability. Furthermore, since the connecting pipe 4 and the water pipe 7 can be connected through the large-diameter pipe port 8, various practical effects such as ease of connection work can be achieved. Furthermore, a small circular hole 10
are formed at the intersections of a plurality of diagonal lines 11 of 60° and 120° arranged in parallel at equal intervals, so that the hexagonal pipe insertion hole 13 can be opened easily and with good appearance. Since it is only necessary to cut the hole while connecting it in a straight line along the hole, it has the advantage of good drilling workability.
