Description

[Detailed explanation of the idea] The present invention relates to the structure of bathroom grates.

In the past, as shown in FIG. 1, both ends of the extension piece 9' were simply cut out and used as drainage openings 11', so that the preliminary drainage groove 10' from the washing area 2' to the drainboard A'. The drainage water flowing into the interior is drained into the preliminary drainage ditch 1.
It flows into the drainage opening 11' cut out at 0', falls from the drainage opening 11' to the outside of the drainage groove 4' of the floor pan 3', flows from there into the drainage groove 4', and drains into the drainage hole 5' at both ends or in the center. It was becoming more drained. Because the drainage distance is long, the preliminary drainage ditch 10'
Water may remain in the center of the tank without being drained,
Furthermore, waste water that generates a lot of foam, such as shampoo, has the disadvantage that foam accumulates in the center and both ends, as shown in FIG.

This invention was made in view of the drawbacks of the conventional example mentioned above, and its purpose is to shorten the drainage distance of drainage by opening communication holes in the legs of the slatted body, and to make the drainage function effective. This can be used to provide a slatted structure for the bathroom.

The gist of the present invention is to form a drain groove 4 in the floor pan 3 between the bathtub 1 and the washing area 2 on the bathroom floor, and to form a drain hole 5 in the drain groove 4.
A drainboard main body 6 having an inverted U-shaped cross section is fitted into this drainage groove 4 so that the upper surface of the drainboard main body 6 and the floor surface of the washing area 2 are approximately flush with each other, and from the lower part of the leg piece 7 of the drainboard main body 6 on the bathtub 1 side. An extension piece 9 having a substantially L-shaped cross section is raised toward the lower end of the apron 8 of the bathtub 1.
A preliminary drainage groove 10 is formed between the leg piece 7 and the extension piece 9, and a drainage opening 11 is formed by cutting out the extension piece 9, and a communication hole is formed for directly communicating the preliminary drainage groove 10 and the drainage groove 4. 12 is provided in the structure of a bathroom drainboard formed by perforating the leg pieces 7.Examples of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 4, the floor pan 3 consists of a washing area 2 and a bathtub installation part 13, and a drain groove 4 is provided across the entire width in between.
It's open.

A plurality of anti-slip protrusions 14 are provided on the upper surface of the slat body 6, and the lower ends of the leg pieces 15 on the side of the washing area 2 of the slat body 6 are cross-shaped to ensure strength. . Further, the bottom of the extension piece 9 is inclined downward toward the leg piece 7 side, and the bottom of the extension piece 9 and the lower edge of the communication hole 12 formed in the leg piece 7 are smoothly continuous. The drainage openings 11 are formed by cutting out the bottom of the extension piece 9 and the leg piece 7 at both ends, one end, or the center of the drainboard A, and a plurality of communication holes 12 are bored therebetween at approximately constant pitches.

The drainboard A fitted in the drain groove 4 is held by fitting the leg piece 15 into the engagement groove 16 between the drain groove 4 and the washing area 2, and the other leg piece 7 is attached to the drain groove 4 and the bathtub installation part 13.
It is placed on pedestals 17 that protrude at regular pitches between the two, and the upper end of the extension piece 9 extends above the upper surface of the drainboard body 6, and is installed in the bathtub installation part 13. It is cut and opposed to the lower end of the apron 8 of the bathtub 1, and closes the gap under the apron 8.

Therefore, the waste water that has flowed into the preliminary drain groove 10 of the drainboard A is drained from the drain openings 11 at both ends, but at the center, it is drained directly to the drain groove 4 through a shorter drainage distance than the communication hole 12. Since the bottom of the extension piece 9 is inclined, the communication hole 12
This will further promote drainage from the water.

As described above, in addition to the drainage openings at both ends, the present invention has communication holes in the slat body and leg pieces that directly communicate the preliminary drainage groove with the drainage groove, so that drainage can flow inside the preliminary drainage groove all the way to the end. Drainage is conducted directly into the drain from the communication hole without running sideways, shortening the drainage distance.Therefore, there is no accumulation of water or bubbles in the preliminary drain, and smooth drainage is achieved. There is an advantage. In addition, communication holes are drilled in the legs of the slat body, which has an inverted U-shaped cross section, so the communication holes are not visible and the appearance is good.In addition, the extension piece is raised toward the bottom end of the apron. This has the advantage that the space under the apron is closed, and there is no risk of objects getting into it or getting your toes stuck in it.
