<Arrangement (fixed) on the horizontal drain pipe D1>
As shown in FIGS. 33 and 34, the drain cover Y is used for a sideways drain pipe D1 installed on a rooftop of a building, a condominium, a detached house (house), a balcony, or the like. For example, the balcony BK1 is composed of a floor F1 and a standing wall W1 and has a drainage hole PT1 as shown in FIGS. 33 and 34. The drainage hole PT1 is formed at the boundary between the floor F1 and the standing wall W1 and penetrates the standing wall W1 sideways. The sideways drain pipe D1 is inserted into the drain hole PT1 and fixed to the floor F1 and the vertical wall W1.
As shown in FIGS. 29 to 32, the drain cover Y bends the cover main body plate 51 and the soft metal core wires 2E to 2H along the bending line N2 (plate length center line α or plate boundary line), for example ( Bend).
At this time, the cover main body plate 51 and the soft metal core wires 2E to 2H are bent in one bending direction or the other bending direction, and the bending angle of the cover main body plate 51 (first and second cover plate portions 65, 66). Adjust θ.
The bending angle θ of the cover body plate 51 is set to the floor wall angle θ2 between the floor F1 and the standing wall W1, and for example, the bending of the cover body plate 51 (first and second cover plate portions 65, 66) is adjusted. If the floor wall angle θ2 = 90 degrees (right angle), the bending angle θ = 90 degrees (right angle) [see FIG. 33 (b)].
The bending angle θ of the cover body plate 51 (first and second cover plate portions 65, 66) is such that the bending line N2 is the turning center (bending center) and the first or second cover plate portions 65, 66 are bent. Adjust by bending in one direction or the other bending direction.
The drain cover Y bent at the floor wall angle θ2 is arranged at the boundary portion so as to cover the opening DK1 of the lateral drain pipe D1.
In the drain cover Y bent at the floor wall angle θ2, the long protrusions 56 and the short protrusions 57 and 58 are placed on the floor F1 to support the first cover plate portion 65 on the floor F, and the second cover plate portion 65 is supported on the floor F. The cover plate portion 66 covers the opening DK1 of the lateral drain pipe D1.
At this time, if necessary, along one or more bending lines of the first cover plate portion 65 (one or a plurality of bending lines in the plate length direction LR), the first cover plate portion 65 and each soft metal core wire 2E ~ 2H is bent (bent), and along one or more bending lines (one or more bending lines in the plate length direction LR) of the second cover plate portion 66, the second cover plate portion 66 and each soft By bending (bending) the metal core wires 2E to 2H, the first and second cover plate portions 65 and 66 are finely adjusted with respect to the floor F or the standing wall W (horizontal drain pipe D).

Can be covered. Further, when the first cover plate portion 65 is supported on the floor F1 by the long protrusions 56 and the short protrusions 57 and 58, a water passage space SA1 is formed (partitioned) between the first cover plate portion 65 and the floor F1.

As shown in FIGS. 29 to 32, the drain cover Y bent at the floor wall angle θ2 bends the spring support plate 17 of the leaf spring body 8 in an “inverted U shape” and guides the leaf spring body 8 into a guide length. By moving along the hole 53, the metal leaf spring 18 is positioned and adjusted to a position corresponding to the opening DK1 of the lateral drain pipe D1.
In the drain cover Y bent at the floor wall angle θ2, each long protrusion 56 and each short protrusion 57, 58 are placed on the floor F1, and the back surface 51B of the second cover plate portion 66 hits the lateral drain pipe D1. At the time of contact, the metal leaf spring 18 is elastically deformed in a curved shape and inserted into the lateral drain pipe D1. At this time, the metal leaf spring 18 is elastically deformed in a curved shape and inserted into the lateral drain pipe D1, and is brought into contact with the inner peripheral DN1 of the lateral drain pipe D1 with a spring force (see FIG. 34).
As a result, the drain cover Y bent at the floor wall angle θ2 is fixed to the lateral drain pipe D1 by the spring force of the metal leaf spring 18.
Water (rainwater), fallen leaves, dust (foreign matter) such as twigs, etc. are flushed from the floor F1 to the drain cover Y. At this time, dust such as fallen leaves and twigs is captured by the drain cover Y. A small amount of water is flowed into the lateral drain pipe D1 from the water passage space SA1 or the like between the first cover plate portion 65 and the floor F1. When the water volume of the floor F1 increases, a large amount of water flows from each drain hole 55 of the first cover plate portion 65, the water passage space SA1, and each drain hole 55 of the second cover plate portion 66 into the lateral drain pipe D1. Is done. The lateral drain pipe D1 drains the water flowing from the drain cover Y laterally.

The drain cover Y is the first cover plate portion 65 at one or a plurality of arbitrary positions in the plate length direction LR depending on the floor wall angle θ2 between the floor F1 and the standing wall W1 and the installation status of the floor F1 and the standing wall W1. By bending the second cover plate portion 66 and the soft metal core wires 2E to 2H, fine adjustment can be made according to the installation conditions of the floor F1 and the standing wall W1.

The present invention is most suitable as a drain cover for a lateral drain pipe.
