[0003] [Patent Document 1] Japanese Patent Publication No. 2022-048672 Summary of the Invention [Problem to be solved by the invention]

[0004] Some strainers with enhanced design have a decorative sheet applied to the top surface of the strainer itself. The outer edge of the decorative material extends from the top surface of the strainer itself to the outer edge. Therefore, if the strainer is repeatedly placed on the floor and leaned against a wall, there is a concern that the outer edge of the decorative material may be scraped or peeled off due to friction with the floor.

[0005] The present disclosure has been made in consideration of the above-described conventional situation, and aims to solve the problem of suppressing damage to the outer peripheral edge of the decorative portion. [Means for solving the problem]

[0006] The perforated plate of the present disclosure is A perforated plate that is detachably installed in a drainage tank, a main body; a thin-film-like decorative portion covering an upper surface portion of the outer surface of the main body portion and a peripheral surface portion extending downward from an outer periphery of the upper surface portion; In a plan view of the main body from above, the outer periphery of the non-decorated portion of the peripheral surface that is not covered by the decorative portion is located outside the outer periphery of the decorative portion.

[0008] <Embodiment 1> A first embodiment of the present disclosure will be described below with reference to Figures 1 to 11. The strainer 10 of the present disclosure is attached to a drainage manhole 40 located at the lowest position on the floor F of the washing area of ​​a bathroom B. By installing the strainer 10 in the drainage manhole 40, the drain outlet (not shown) in the drainage manhole 40 can be hidden.

[0009] The strainer 10 is a component that integrates a main body 11 made of synthetic resin and a decorative portion 18 for enhancing the design of the strainer 10. As shown in Figures 2 and 3, the main body 11 has a horizontal plate-like portion 12 and four legs 13. In a plan view of the strainer 10 from above, the plate-like portion 12 is generally rectangular. More specifically, the four corners of the plate-like portion 12 form quarter-circular arcs. The four legs 13 are portions that protrude downward from the four corners of the plate-like portion 12. A rubber spacer 14 is attached to the underside of each leg 13. As shown in Figure 6, when the strainer 10 is viewed horizontally from the front, back, left, and right, the spacer 14 is positioned inward from the outer surfaces of the legs 13.

[0010] Of the outer surface of the main body portion 11, the upper surface portion 15 is composed of only one flat surface. As shown in FIG. 5 , the portion of the outer surface of the main body portion 11 that protrudes diagonally downward from the outer peripheral edge 15E of the upper surface portion 15 is defined as the peripheral surface portion 16. The peripheral surface portion 16 is the upper end portion of the outer surface of the plate-shaped portion 12. Of the outer surface of the main body portion 11, the region below the peripheral surface portion 16 is defined as the outer peripheral surface 17 of the main body portion 11.

[0011] In a horizontal view, the peripheral surface portion 16 is composed of a decorative-side first convex surface 21, a decorative-side second convex surface 22, a concave surface 23, and a non-decorative-side convex surface 24. The decorative-side first convex surface 21 is tangentially connected to the upper surface portion 15 and is composed of a curved surface that protrudes obliquely downward from the outer peripheral edge 15E of the upper surface portion 15 toward the outer periphery. The decorative-side second convex surface 22 is tangentially connected to the decorative-side first convex surface 21 and is composed of a curved surface that protrudes obliquely downward from the outer peripheral edge 21E of the decorative-side first convex surface 21 toward the outer periphery. The curvature of the decorative-side second convex surface 22 is greater than the curvature of the decorative-side first convex surface 21.

[0012] The concave surface 23 is tangentially connected to the decorative-side second convex surface 22 at an upper inflection point 25, and is formed by a curved surface that protrudes obliquely downward from the outer peripheral edge 22E of the decorative-side second convex surface 22 toward the outer periphery. The non-decorative-side convex surface 24 is tangentially connected to the concave surface 23 at a lower inflection point 26, and is formed by a curved surface that protrudes obliquely downward from the outer peripheral edge 23E of the concave surface 23 toward the outer periphery. The outer peripheral edge 24E of the non-decorative-side convex surface 24 coincides with the lower edge 16E of the peripheral surface portion 16. The lower edge 16E of the peripheral surface portion 16 is tangentially connected to the upper end of the outer peripheral surface 17 of the main body portion 11.

[0013] In a horizontal view, a plane circumscribing the peripheral surface portion 16 is defined as an imaginary plane 27. The imaginary plane 27 circumscribing the peripheral surface portion 16 at two points: a decorative-side outer contact point 28 on the decorative-side second convex surface 22, and a non-decorative-side outer contact point 29 on the non-decorative-side convex surface 24. The region of the peripheral surface portion 16 between the decorative-side outer contact point 28 and the non-decorative-side outer contact point 29 is defined as a non-contact recess 30. In a horizontal view, the entire region of the non-contact recess 30 is located inside the imaginary plane 27.

[0014] The decorative portion 18 is formed by integrally press-molding a resin-impregnated nonwoven fabric having a colored nonwoven fabric, or by painting. The decorative portion 18 is formed over the entire upper surface portion 15 and the upper end region of the peripheral surface portion 16. In a horizontal view, the outer peripheral edge 18E of the decorative portion 18 is located between the decorative-side outer contact point 28 and the non-decorative-side outer contact point 29. In other words, the outer peripheral edge 18E of the decorative portion 18 is located within the concave surface 23 of the non-contact recess 30. The area of ​​the outer surface of the main body portion 11 where the decorative portion 18 is not formed is defined as the non-decorative portion 31.

[0015] The region of the non-decorative portion 31 located within the peripheral surface portion 16 is defined as the non-decorative planar visible region 32. The non-decorative planar visible region 32 is a region below the outer peripheral edge 18E of the decorative portion 18. The non-decorative planar visible region 32 is a region of the peripheral surface portion 16 that is outer than the outer peripheral edge 18E of the decorative portion 18 in a planar view. In a planar view, the outer peripheral edge 32E of the non-decorative planar visible region 32 coincides with the outer peripheral edge 31E of the non-decorative portion 31 in the peripheral surface portion 16 and also coincides with the lower edge 16E of the peripheral surface portion 16.

[0016] When the strainer 10 is set up perpendicular to the floor F and the outer peripheral surface 17 of the main body 11 is in surface contact with the floor F, the non-contact recess 30 where the outer peripheral edge 18E of the decorative portion 18 is located is spaced upward from the floor F. Therefore, the outer peripheral edge 18E of the decorative portion 18 does not come into contact with the floor F. As shown in FIG. 7, when the strainer 10 is set up at an angle and the peripheral surface 16 is in contact with the floor F, even if the decorative-side outer contact point 28 and the non-decorative-side outer contact point 29 come into contact with the floor F, the non-contact recess 30 where the outer peripheral edge 18E of the decorative portion 18 is located is spaced upward from the floor F, as shown in FIG. 8. Therefore, the outer peripheral edge 18E of the decorative portion 18 does not come into contact with the floor F.

[0017] As shown in FIG. 9, when the strainer 10 is lifted obliquely within the drainage manhole 40, the decorative-side outer contact point 28 and the non-decorative-side outer contact point 29 come into contact with the inner surface 41 of the drainage manhole 40. However, as shown in FIG. 10, the non-contact recess 30 where the outer peripheral edge 18E of the decorative portion 18 is located is spaced laterally from the inner surface 41 of the drainage manhole 40. Therefore, the outer peripheral edge 18E of the decorative portion 18 does not come into contact with the inner surface 41 of the drainage manhole 40. As shown in FIG. 9, when the strainer 10 is lifted obliquely within the drainage manhole 40, even if the lower ends of the legs 13 on the outer peripheral surface 17 of the main body 11 approach the inner bottom surface 42 of the drainage manhole 40, as shown in FIG. 11, the spacers 14 abut against the inner bottom surface 42 of the drainage manhole 40, so the lower ends of the legs 13 do not come into contact with the inner bottom surface 42 of the drainage manhole 40. Therefore, there is no risk of the inner bottom surface 42 or the lower ends of the legs 13 being damaged.

[0018] The strainer 10 of this embodiment 1 is removably installed on a drainage manhole 40 provided on the floor F of the bathroom B. The strainer 10 comprises a main body 11 and a decorative portion 18. The decorative portion 18 is a thin-film-like portion of the outer surface of the main body 11 that covers the upper surface 15 and the peripheral surface 16 that extends downward from the outer peripheral edge 15E of the upper surface 15. In a plan view, the outer peripheral edge 31E of the non-decorative portion 31 of the peripheral surface 16 that is not covered by the decorative portion 18 is located outside the outer peripheral edge 18E of the decorative portion 18. According to this configuration, when the outer surface 17 of the main body 11 is brought into contact with the floor F or the inner surface (inner side surface 41 or inner bottom surface 42) of the drainage manhole 40, the outer edge of the decorative portion 18 does not come into contact with the floor F or the inner surface (inner side surface 41 or inner bottom surface 42) of the drainage manhole 40, thereby suppressing damage such as peeling or scraping at the outer edge 18E of the decorative portion 18.

[0019] A non-decorative planar visible region 32 of the non-decorative portion 31 that appears in a plan view is inclined so as to descend toward the outer peripheral edge 31E of the non-decorative portion 31 in a horizontal view when the peripheral surface portion 16 is viewed horizontally. In a horizontal view, the outer peripheral edge 18E of the decorative portion 18 is located inside an imaginary plane 27 that circumscribes the decorative-side second convex surface 22 of the decorative portion 18 and the non-decorative-side convex surface 24 of the non-decorative portion 31. With this configuration, even if the decorative-side second convex surface 22 and the non-decorative-side convex surface 24 come into contact with the floor surface F or the inner surface of the drainage manhole 40 (the inner surface 41 or the inner bottom surface 42), the outer peripheral edge of the decorative portion 18 does not come into contact with the floor surface F or the inner surface of the drainage manhole 40 (the inner surface 41 or the inner bottom surface 42).

[0020] When viewed horizontally, the non-contact recess 30, which is the area of ​​the peripheral surface 16 between the decorative side outer contact point 28 and the non-decorative side outer contact point 29 circumscribed by the imaginary plane 27, is composed of a concave curved surface (part of the decorative side second convex surface 22, the concave surface 23, and part of the non-decorative side convex surface 24) so ​​that at least the non-decorative portion 31 is positioned inside the imaginary plane 27.

[0021] The upper surface 15 of the main body 11 is formed entirely of flat surfaces. When the upper surface 15 is formed entirely of flat surfaces, the curvature of the decorative portion 18 at the outer periphery 15E of the upper surface 15 is smaller than when the upper surface is curved so that the center is concave. By forming the upper surface 15 entirely of flat surfaces, it is possible to reduce stress generated at the outer periphery of the upper surface 15 when the outer periphery 15E of the upper surface 15 comes into contact with the floor or the inner surface (inner surface 41 or inner bottom surface 42) of the drainage basin 40.

[0022] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure. When viewed horizontally, the area of ​​the peripheral portion 16 between the decorative side outer contact point 28 and the non-decorative side outer contact point 29, which are circumscribed by the imaginary plane 27, may be a plane that coincides with the imaginary plane 27 in the area of ​​the non-decorative portion 31 that is separated from the outer peripheral edge 18E of the decorative portion 18. The horizontally viewed shape of the decorative portion 18 on the peripheral surface portion 19 may be a stepped shape made up of only straight lines, or a shape made up of straight lines and curved lines. The horizontally viewed shape of the non-decorated planar visible area 32 on the peripheral surface portion 19 may be a stepped shape made up of only straight lines, or a shape made up of straight lines and curved lines. The boundary portion of the peripheral surface portion 19 between the outer periphery 18E of the decorative portion 18 and the non-decorated planar visible region 32 may have a stepped shape when viewed in horizontal view.
