JPS6014854Y2 - Perforated plate for drain hole - Google Patents

Description

[Detailed description of the invention] The present invention relates to a perforated plate that is used by being attached to the top surface of a drain trap body or a drain outlet, and particularly relates to a perforated plate for a drain outlet that can be installed and removed without using any other tools. It is.

A conventional drainage perforation plate has a large number of through holes, and each hole has a width of 8wt+ or less to prevent large particles from passing through.

Therefore, a special disassembly and assembly tool is required to remove the drain perforation from the drain or the trap body during cleaning or the like.

Particularly, in the case of a perforated drain plate that is attached or removed by rotating the perforated plate, it is extremely troublesome to attach or remove the perforated plate.

The present invention has at least two holes on the top surface that are large enough to allow fingers to be inserted into the perforated plate, and is configured so that the fingers can be inserted into these holes and held. This is a perforated drain plate that eliminates all drawbacks.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

The perforated drain plate 1 according to the present invention is made of synthetic resin, metal, etc., and has an overall circular shape as shown in FIG.

This drain hole plate 1 is provided with a large number of circular or elongated holes 2 through which water can pass.

Further, the drain hole plate 1 has two holes 3 large enough to insert fingers.

These holes 3 are formed at opposing positions and have a depth such that the perforated plate can be held by inserting fingers into the holes.

In addition, a through hole 5 is bored in the bottom 4 of each of the holes 3, so that even though drainage water passes through, large dirt does not pass through.

The perforated drain plate 1 of the present invention as described above is not limited to that illustrated in FIGS. 1 and 2.

As illustrated in FIG. 4, a plurality of holes 3 may be formed, and a large number of through holes 5 may be bored in the bottom 4 of each hole 3.

Although not shown, two holes may be formed relatively close to each other, and one or more small through holes may be bored at the bottom of the holes.

In short, two or more holes 3 into which fingers can be inserted are formed, and the drain hole plate 1 can be held between the fingers by inserting the fingers into these holes 3. It is sufficient that a through hole 5 is bored in the bottom 4 of the container so that waste water can pass therethrough, but large garbage cannot pass therethrough.

The perforated drain plate 1 of the present invention is used to prevent clogging due to dirt by being attached directly to a drain outlet in a bathroom or the like, or attached to a strainer of a drain trap.

Figure 3 shows a drainage trap 7 with a built-in strainer 6.
The strainer 6 is shown as an example of a case in which the strainer 6 is embedded in the drain port 8 and the drain port perforated plate 1 shown in FIG. 1 is attached to the strainer 6.

To attach the drain hole plate 1 to the strainer 6, use the hole 3
This is done by inserting one's fingers into the drain opening plate 1, and placing and fitting it above the strainer 6.

At this time, no special assembly tools are required.

When the drainage port perforation plate 1 is installed in this manner, drainage water passes through the through hole 2 and the through hole 5.

However, large debris during drainage does not pass through the through hole 2 and the through hole 5, but accumulates on the upper surface of the drain plate 1 and in the hole 3, so that clogging of the drain pipe, etc. can be prevented.

Further, when cleaning the drain perforation plate 1, the strainer 6, etc., insert fingers into the holes 3, grasp the drain perforation plate 1, and remove it from the strainer 6.

In this case, there is no need to use special disassembly tools.

Although not shown, even if the perforated plate for the drain port is attached to or removed from the drain port by rotating it, it can be rotated by inserting your fingers into the hole and holding it between the holes. Since it can be moved, special disassembly and assembly tools are not required.

As described above, the perforated drain plate of the present invention has at least two holes into which fingers can be inserted, so it is easy to attach or remove it from the drain or strainer. This can be easily done without using any other tools, since the fingers can be inserted into the holes and held.

This is particularly effective in a perforated drain plate that can be attached or removed by rotating.

Furthermore, since a through hole is provided at the bottom of the hole, there is no fear that drainage water will accumulate in the hole.
