[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a drain pipe such as a sink and a drain pipe provided in a wall surface.

[0002]

2. Description of the Related Art Generally, drainage of a basin provided in a wash basin is performed by providing a drain pipe on a floor surface under the wash basin. There is a drainage method that is performed by connecting to a pipe.

[0003] In such a drainage system, conventionally, a straight pipe connecting pipe is connected to a drain trap provided immediately below a basin drain port, and is connected to a drain pipe provided on a wall surface with a predetermined drain gradient. Is going.

[0004]

[Problems to be Solved by the Invention] However, in such a connection structure, since the drain trap is directly connected to the drain pipe in the wall, construction errors cannot be absorbed, and the construction position of the drain pipe in the wall and the washing surface cannot be absorbed. It is necessary to accurately determine the position where the drain pipe is taken out of the vessel. In addition, even if the positioning is performed accurately, the level of the wash basin is often adjusted after the piping work in the wall surface, so that the position of the drain trap changes and it becomes difficult to connect the drain pipe. .

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a drain pipe connection structure that can be easily connected regardless of the presence or absence of a construction error.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The features of the present invention will be specifically described below with reference to the embodiments shown in the drawings.

FIG. 1A is a front view of a vanity incorporating the drainage pipe connecting structure of the present invention, and FIG. 1B is a side view of the same.

The bathroom vanity is made of anodized aluminum and its main members are supported by a supporting column 4 for a washbasin 1, a mirror 2, and a lighting fixture 3, and a supporting leg is provided at a lower end of the supporting column 4. 5 are provided and fixed to the floor.

The basin 1 has a single-lever mixer tap 6.
Is connected to an external water supply / hot water supply system via a water supply pipe 6a and a hot water supply pipe 6b. Reference numeral 7 denotes a soap receiver arranged on the upper surface of the basin. Further, a drain trap 8, a drain pipe 9 and the like are connected to a lower portion of the basin 1, and are connected to a drain pipe 18 provided in a wall surface and discharged to the outside.

As shown in an exploded perspective view of FIG. 2A and a cross-sectional view of FIG. 2B, the support column 4 has an elliptical cross section having a space therein, and has a support rod insertion hole having a rectangular cross section. 4a, and a mounting pipe 3 for the lighting fixture 3 at both inner ends.
a is provided with a mounting hole 4b which can be inserted and fixed. 4c is
The back plate is formed to have the same curvature as that of the support column 4 and is attached to the support column 4 with screws. Reference numerals 4d and 4e are insertion holes for inserting a drain pipe.

As shown in FIGS. 3 (a) and 3 (b), the supporting leg 5 for fixing the vanity table to the floor F is provided with a leg 5a and a cover 5f for covering the leg 5a. A support rod 5b that can be fitted into the support rod insertion hole 4a of the support column 4 protrudes from the seat 5a, and an adjuster 5c for height adjustment is provided.
Are screwed together, and a floor fixing wood screw 5d and a rubber bush 5e are further provided. On the other hand, the aluminum cover 5f has a columnar projection 5g that can be engaged with the bush 5e provided on the leg 5a and an elliptical insertion hole 5h through which the support column 4 can be inserted. After fixing to the floor, the cover 5f is put on from above.

FIG. 4 is a detailed view showing a drain pipe connecting structure of the wash basin. A drain trap 8 is provided at a drain port 1a of the basin 1, and a drain pipe 9 is connected to the drain trap 8. . The drain pipe 9 is provided with a predetermined drain gradient, is inserted through the insertion hole 4e of the support column 4, and has a first elbow pipe 10 having a bending angle of 90 degrees connected to the other end. Further, an adjustment tube 11 for length adjustment is connected to the first elbow tube 10. A second elbow pipe 12 having a bend angle of 90 degrees is connected to the other end of the adjustment pipe 11. The second elbow pipe 12 and a drain pipe 18 in the wall are connected by a drain pipe 13. doing. In the drawings, reference numerals 14, 15, and 16 denote connection nuts, and reference numeral 17 denotes a flange for mounting on a wall surface.

As described above, in this embodiment, the first elbow pipe 1
An adjusting tube 11 for adjusting the length is provided between the 0 and the second elbow tube 12. For this reason, by cutting the length of the adjusting pipe 11 and adjusting it appropriately, the drain pipes 9, 13 connecting the drain trap 8 and the drain pipe 18 in the wall surface can be easily located.

In this embodiment, the drain port 1 of the basin 1 is provided.
An insertion hole 4e is provided in the support pillar 4 located directly behind the hole a, and a drain pipe 9 from a drain trap 8 is inserted into the insertion hole 4e. For this reason, the elbow pipes 10, 12 and the adjustment pipe 11 are hidden by the support pillars 4 and have excellent appearance.

[0017]

As described above, according to the present invention, a first elbow pipe and a second elbow pipe are provided, and these two elbow pipes are connected by a snapper adjusting pipe. Therefore, by adjusting the length of the connecting pipe, it is possible to absorb the construction error of the drainage pipe on the building side provided in the wash basin and the wall, and the position of the drain trap and the drain pipe in the wall can be absorbed. The installation efficiency of the drainpipe is dramatically improved without the need to accurately determine the installation position .
Located between the washing surface unit and the wall surface on the back of the support pillar for supporting the basin, the l, by positioning the second elbow pipe and adjusting tube, the facilities in which these pipes are not exposed Obtainable.
