Description

[Detailed description of the invention] The present invention relates to a drainage trap, more specifically, a drainage trap that is installed under the floor of a drainage section of a bathroom washing area, etc., and drains water from the bathroom washing area, etc. to a sewer pipe. To provide a drainage trap in which a drainage perforation plate is securely locked in an opening and can be rationally removed.

A plurality of small protrusions of the same shape are provided inside the drain opening of the drain trap body, and on the other hand, the same number of notches into which the above-mentioned small protrusions fit loosely are formed on the inside of the perforated plate. Conventionally, drain traps have been provided in which the drain traps are fitted.

In such conventional products, since all the small protrusions are the same size, the perforated plate can be attached or removed at any location as long as the small protrusions and the notches match.

With something like this, it is convenient to install the perforated plate, but
On the other hand, it is easy to remove, and as a result, the perforated plate may be removed naturally, resulting in a lack of stability.

The present invention is a drain trap that eliminates the above-mentioned drawbacks by providing a drain trap body with a pair of opposing protrusions on one side and a pair of opposing protrusions on the other with different sizes. It is.

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

Figures 1 to 4 show the drainage trap of the present invention, in which Figure 1 is an exploded sectional view, Figure 2 is a perspective view of the inner lid with one part cut away, and Figure 3 is a drainage trap with one part cut out. FIG. 4 is a perspective view of the perforated plate, and a sectional view showing how the drainage perforated plate is attached.

As illustrated in FIG. 1, the trap consists of a drain trap main body 1 having an inner lid 2 on the upper side and a drain perforation plate 3.

This inner cover 2 has a circular drain opening 4, and is removable by screwing it to the floor 5 so that the drain trap body 1 can be easily attached to the floor 5.
It is not limited to this.

Although not shown, a circular drain opening may be provided directly in the drain trap body.

Further, the inner cover may be attached to the drain trap body by means other than screwing.

As shown in FIG. 2, the circular drainage opening 4 in the inner lid 2 has four protrusions 6, 6 and 7 on its upper inner surface.
7 is set opposite.

These protrusions 6, 6 and 7, 7 have a pair of opposing protrusions of the same size, and one pair of opposing protrusions is larger than the other pair of opposing protrusions. .

That is, the pair of protrusions 6, 6 facing each other have the same size,
The protrusions 7, 7 are of the same size.

Moreover, one pair of opposing protrusions 6.6 is larger than the other pair of opposing protrusions 7,7.

Further, as illustrated in FIG. 3, the drainage perforation plate 3 has a locking portion 9 on the lower surface of the drainage perforation plate 3, which has a large number of through holes 8 for drainage.
It is a formality.

Moreover, an engaging groove 10 is provided around the outside of the locking portion 9, and each projection 6 of the inner lid 2 is provided in the engaging groove 10. 6.
7°7 is designed to engage.

Furthermore, each protrusion 6 of the inner lid 2 is attached to the locking portion 9. 6.
7. 7 and each protrusion 6. 6. 7. 7
Notches 11, 11 and 12, 12 are provided, into which each can be loosely fitted.

That is, the locking part 9 at a position corresponding to the protrusions 6, 6 of the inner lid 2 is provided with a notch 11.11 that is slightly thicker than the protrusions 6, 6, and corresponds to the protrusions 7, 7. At the position, protrusion 7,
When a notch 12.12 that is slightly thicker than 7 is provided, and one notch 11.11 and the protrusions 6, 6 match, and the other notch 12, 12 and the protrusions 7, 7 match, respectively. To,
The drainage perforation plate 3 can be attached and removed.

The inner lid 2 is not limited to those illustrated in FIGS. 1, 2, and 4.

Although not shown, for example, six protrusions may be provided on the inner surface of the drainage opening.

In this case, although not shown, it is necessary to provide six notches at corresponding positions in the locking portion of the drainage perforation plate.

However, if the number of protrusions and notches is too large, it becomes convenient to install and remove the drainage perforation plate, but on the other hand, the drainage perforation plate often ends up being removed even if it rotates slightly on its own. , their number is optimally 4 or 6.

Moreover, the shape of each protrusion and the drainage perforation plate are not limited to those shown in the example.

For example, the locking portion of the drain plate may be engaged with a projection, and a cutout portion into which the projection can be loosely fitted may be provided.

In FIG. 1, reference numeral 13 indicates a water sealing plate, 14 indicates a drainage outlet, and 15 indicates a sewage pipe connected to the drainage outlet.

As shown in FIG. 1, the drain trap of the present invention as described above is installed, for example, in a drainage section of a bathroom washing area, and a sewer pipe 15 is connected to the drain outlet 14 of the drain trap main body 1.

In addition, as shown in FIG. 4, a drain plate 3 is attached to the drain opening 4 of the inner lid 2, and the drain from the bathroom washing area is transferred to the drain pipe 15.
It is used to flow to.

To attach the drain eye plate 3 to the drain opening 4, attach the drain eye plate 3 to the drain opening 4.
The notches 11, 11 on one side are aligned with the protrusions 6, 6 on one side of the drainage opening 4.

Then, the other notch 12.12 also has the other protrusion 7,
7.

Next, the drainage perforation plate 3 is inserted into the drainage opening by fitting the protrusions 6, 6 on one side into the notches 11.11 on the other hand, and the protrusions 7, 7 on the other side into the notches 12.12 on the other side. Push it inside 4.

Thereafter, the drain plate 3 is rotated in either direction.

When the ice drain plate 3 is rotated, the respective protrusions 6, 6 and 7, 7 are engaged with the engagement groove 10 of the locking portion 9, and the drain plate 3 is attached.

In addition, when removing the drainage perforation plate 3, rotate the drainage perforation plate 3 fitted in the drainage opening 4 and insert one notch 11. What is necessary is to match the protrusions 6, 6 of.

Since the present invention has the above-described configuration, there are two or three locations where the protrusion of the drain opening and the notch of the drain plate match.

That is, when four of the projections and notches are provided, there are only two positions where they match, and these are the positions where the drainage eye plate is rotated by a maximum of 180 degrees.

In addition, for those provided with six protrusions and notches,
There are 3 places that match, and the drainage eye plate is the maximum of 1.
This is the position rotated 20 degrees.

Therefore, there are 2 to 3 degrees of freedom in attaching and removing the drainage perforation plate, so it is possible to install the drainage perforation plate even in a narrow space or in a situation where installation is difficult.

In addition, it not only cannot be removed unnecessarily, but also prevents the drain plate from rotating slightly due to drainage from the floor and being removed naturally, which has many effects as a drain trap. be.
