Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a cap to be attached to the opening surface of a drainage pipe provided on a slope that has been earth-stopped by, for example, assembling a stone wall or spraying concrete.

(B) Conventional technology The water draining pipe is for draining water accumulated in the slope, and the base end side is buried in the soil with the opening at the tip protruding from the slope. There was a water drainage hole on the slope.

C. Problems to be solved by the device Muddy water enters from the base end of the pipe buried in the soil, and sand dust, moss spores, and weed seeds, etc. come in from the opening at the tip. Therefore, the inside of the pipe becomes the best environment for the growth of moss and weeds, the plants infest, the aesthetics are impaired, and the drainage function becomes insufficient. In addition, drainage pipes are a perfect place for birds to nest and often become a place for raising children, which not only impairs the drainage function, but also pollutes the surrounding area with bird droppings and impairs the beauty. Be done. Furthermore, there are some mischiefs in which empty cans etc. are plunged.

D. Means for Solving the Problems The present invention shuts out dust, moss spores and weed seeds, bird entry, and empty can insertion without damaging the drainage function. A cap for a drainage pipe intended to create an environment that is not suitable for plant growth even if it enters the pipe. A plurality of elastic legs which are formed on one side surface of the shielding plate having a shape and a size in which a clearance for extraction is formed, projecting from the peripheral edge thereof in a direction orthogonal to the plate surface, and having an intermediate portion bulging in the outer peripheral direction of the shielding plate. Is equipped with.

E action By pressing the intermediate bulging part of the elastic leg inward from the surroundings with the inner wall of the drainage pipe, just push it in until the shield plate and the opening surface are flush with each other, and it fits in. Due to elasticity, it can be applied even if the inner diameter is slightly different or the opening surface is inclined due to the difference in wall thickness of the drainage pipe. Further, a space for draining water is secured between the inner peripheral wall of the drainage pipe and the outer peripheral edge of the shielding plate, and dust, spores of moss and seeds of weeds are prevented from coming in from the outside, and entry of birds is prevented.

F. Embodiment An embodiment of the cap for a water draining pipe according to the present invention will be described with reference to the drawings.

In the cap for drain pipe shown in FIG. 1, 1 is
It is a shield plate having a corrugated outer peripheral shape which is slightly smaller than the desired inner diameter of the water draining pipe, and stoppers 2 are projected in the outer peripheral direction at symmetrical portions of the peripheral edge of the shield plate 1. There is a step in one direction with respect to the shield plate 1. The corrugated peripheral edge has six peaks and troughs at six points, and the other surface of the shield plate 1 is provided with legs 3, 3, ... These are integrally formed of synthetic resin. And legs 3, 3 ...
, The middle portions 3a, 3a, ... bulge in the outer peripheral direction of the shield plate 1,
It has elasticity.

The drain pipe cap thus formed is
As shown in the drawing, from one end of the drainage pipe 4 which is exposed from the slope, the intermediate portion 3a of the all elastic leg 3 is brought into contact with the inner wall of the drainage pipe 4, and the inner surface of the drainage pipe 4 is directed toward the center of the drainage pipe 4. Hold it down and push it in. Then, the stoppers 2 and 2 come into contact with the edge of the water draining pipe 4, and the cap is attached to the shield plate 1.
And the opening surface of the pipe are flush with each other.
Then, it suffices to apply an adhesive between the intermediate portion 3a of the leg 3 and the inner wall of the drainage pipe 4 and fix it. The adhesive can be applied to the intermediate portion 3a of the leg 3 in advance,
It can also be detachably attached without applying an adhesive material.

The cap for the water draining pipe of this embodiment can be accurately and easily positioned when fitted by the stopper. Although there are some drainage pipes having the same nominal diameter but different inside diameters between the drainage pipes 4 and 4'due to the difference in wall thickness, since the legs have elasticity, the inside diameter may vary slightly. 4A and 4B, and even if the opening surface of the drainage pipe 4 is inclined, it can be attached as shown in FIG. In the opening of the drainage pipe with the drainage pipe cap attached in this way, a gap for drainage is secured between the inner peripheral wall of the pipe and the outer peripheral edge of the shielding plate, so that the drainage function is not hindered. Absent. It is desirable that this drainage clearance be about 1/3 of the cross section of the pipe opening. And since the opening is covered with a shielding plate, it has a good aesthetic appearance, and the entry of dirt, moss spores and weeds is blocked, and even if dirt, moss spores or weeds enter,
It blocks the sun's rays and hinders the growth of plants, preventing clogging in pipes. Moreover, even if a bird tries to make a nest in the pipe, the shielding plate prevents the bird's entry, and the surrounding area is not polluted by bird droppings, and it is possible to prevent the mischief of children plunging an empty can.

In the cap for the water draining pipe of the present embodiment, the shielding plate has a corrugated outer peripheral shape, but the shape and size are such that a gap for draining water is formed between the opening surface of the water draining pipe and the inner surface of the opening. Any shape such as a perfect circle, a polygon or the like may be used as long as the number of legs is two or more. Further, the stopper may or may not be provided, and the time of attachment to the drainage pipe does not matter before or after the burial on the slope.

According to the present invention, it is possible to easily realize a revolutionary concept such as attaching a cap to the water draining pipe, which was not possible in the past, to improve aesthetics and prevent clogging in the pipe, and also various pipes. The actual profit is enormous because it can be adapted to the form and can be attached to the existing drainage pipe as well as the one to be constructed in the future.
