Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a drain filter, 4? This invention relates to a filter for drains used in drains installed in bathhouses and the like.

(Prior art and problems) As shown in Figure 7, a drain 2 installed on the floor 1 of a bathhouse or the like drains a large amount of waste water at once, for example when the bath plug is pulled out. 6th because there is a split leading to tube 3.
As shown in the figure, a lid 4 is fitted with a hole 4a occupying a relatively large area.

Therefore, hair, dirt, etc. pass through the lid 4 and the drain pipe 3 becomes clogged.

Therefore, it has recently been considered to add a filter to the drain port 2 to prevent the drain pipe 3 from clogging.

There are many types of drain ports 2 in terms of size and shape.

It is necessary to produce filters of a large number of sizes and shapes depending on the drain outlet 2, which increases the production cost, and there are problems such as it is not easy to attach to an existing drain outlet.

(Purpose of the Invention) The present invention has been made to solve such problems, and can be easily installed in existing single-layer drains in size and shape, thereby preventing clogging of the drains. The object of the present invention is to provide a filter for a drain outlet that can be used as a drain outlet.

(Structure of the Invention) In order to achieve this object, the drain filter of the present invention has the following features:
An opening is formed in the center of a flat plate provided with a separation indication line concentrically displaying the peripheral edges of a plurality of drainage ports having at least one of different shapes and sizes. It is characterized by being provided with.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

Figures 1 and 2 show an embodiment of the present invention; 9 a thin flat plate approximately 20 cm square 5 made of a water-resistant and translucent material such as synthetic toilet fat;
The cutting indication lines 6al, 6b, 6c, 6d are formed by concentrically displaying the periphery of a number of circular drainage holes with different diameters.
6el, 6f, and cutting indication lines 7a and 7b concentrically displaying the periphery of a plurality of rectangular drainage ports of different sizes.
, 7c, 7d, 7e Furthermore, a triangular cutting indicator line 8 is provided by a perforation, and a circular opening 9 is formed in the center of the flat plate 2, and this opening 91 The filter body 10 is provided with a bag-like filter body 10 made of a flexible, fine-mesh net.

Further, in this embodiment, an engaging member 11 for engaging a drain port lid, which will be described later, is installed in the opening 9. This engaging member 11
is substantially rectangular and is formed integrally with the flat plate 5. A through hole is formed in the center of the adhesive, and this through hole 12 communicates with a through hole 14 having a larger diameter than this through hole 9 through a communicating elongated hole 13. has been done.

In order to use the drain outlet filter 15 having such a configuration, first, the drain outlet 2 where the drain outlet filter is to be installed is used.
Cutting indication line (5a) that matches the shape and size of the peripheral edge of
, 7a, B).

Cut out the flat plate 5 according to the appropriate cutting direction line.

At this time, in this embodiment, since the flat plate 5 has translucency, the flat plate 5 is directly connected to the drain port 2 as shown in Fig. 2) 3.
By overlapping the lines, it is possible to easily select a cutting line that matches the drain port 2, and since the cutting line is formed by a perforation, there is no need to use cutting tools such as scissors or a knife. Can be separated. Even if the cutting line is formed by discontinuous cuts instead of perforations, the same edge will be obtained.

Then, as shown in FIG. 4, a drain filter 15 cut to a size suitable for the drain port 2 is engaged with a lid rest 4 fitted to the drain port 2 and suspended. This engagement is achieved by inserting a bolt 16a from the lower surface into a through hole 4b normally provided in the center of the lid 4, and using engagement protrusions 16 formed on the upper and lower surfaces of the drain filter! First, the engagement head 17 at the lower end of the engagement protrusion 6 is inserted into the through hole 14, which is formed to have a larger diameter than the engagement head 17. Insertion, then long hole drilling 3
is passed through, moved laterally, and inserted into a through hole n having a slightly larger diameter than the shaft 18 of the engaging protrusion 16 formed at the center. In addition, at this time, there is a long hole! 3 is slightly narrower than the axis 18 of the engagement protrusion 16, but since the flat plate 5 is formed of a thin plate, the elongated hole 14
The hole wall of 1 is warped, allowing forcible lateral movement, and the lid 4
and the drain filter 15 can be engaged with each other.

Next, the lid body 4 can be used by fitting it into the drain port 2 as shown in Fig. 8g5 in the same way as before. If so, remove the lid body 4 from the drain port 2, and with the hand II opposite to the above-mentioned engagement, remove the drain filter 15 from the lid body 4, remove any dirt, etc. inside the filter body 10, and replace it with a new one. Replace it with a suitable drain outlet filter 15 and attach it to the drain outlet 2 again as described above.

Note that although this embodiment is configured to be used by engaging with the lid rest 4, it may be configured without the engaging member 11. In this case #'i, first, the drain filter 15 according to the present invention is attached to the drain outlet 2, and then the lid 4 is placed on top of the drain outlet filter 15.

In addition, in this embodiment, a cutting line indicating both various shapes and sizes is provided on the flat plate 5, but when a plurality of pieces of the same type-f1 shape of different sizes are provided. is also used in the same way, and since it is generally easy for the user to know the shape of the drain to which the drain filter of the present invention will be attached at the time of purchase, such a configuration can also function satisfactorily. In the case of a display of several different shapes such as circles, squares, and triangles with the same size, that is, the same diameter, side length, height, etc., 1
One drain filter can handle various shapes of drains.

Furthermore, instead of cutting line indicating lines such as rectangular lines having various shapes and sizes, cutting line indicating line with square scale may be provided.
In this case, it is extremely convenient to adapt it to drains of various sizes and shapes, such as rectangular, triangular, fan-shaped, etc. Yet again.

In this embodiment, the filter body 10 is made of a net, but it may also be made of a bag-shaped metal plate formed with a large number of small holes. There is little clogging, and it is easy to remove dirt.

(Effects of the Invention) The present invention has an opening formed in the center of a flat plate on which a cutting indication line is formed by concentrically displaying the periphery of a plurality of drainage ports having at least one of different shapes and sizes. In addition, since the filter body is installed in this opening, there is no clogging of the drain pipe when it is attached to the drain, and drainage is good, and it can be easily attached to drains of various shapes and sizes. You can wear it twice, and the production price is low.

In addition, if the cutting line is made up of perforations or discontinuous cuts, tools such as scissors are not required for cutting, and if the flat plate is made of a translucent material, the drainage hole can be removed. It is possible to select a cutting line that directly overlaps and matches the drain port, and it is possible to save the labor of measuring the shape and size of the drain port. Furthermore, according to the structure in which the engagement member for the drain outlet cover is installed in the opening formed in the center of the flat plate, the drain filter can be removed when the cover is attached to or removed from the drain outlet. It is convenient to put on and take off at the same time.
