Description

[Detailed description of the present invention] The present invention relates to a drain pipe cover for a gutter used to drain rainwater collected by a gutter to a rainwater basin or a drainage channel through a water pipe buried underground. And it is used for connection between the downspout and the water pipe.

[Prior art] Conventionally, in order to connect a downspout to a water pipe, a structure in which the lower end of the downpipe is fitted into a connection section of a pre-sleeved water pipe is generally used. Since the downspout cannot be removed later, cleaning cannot be performed when dust accumulates in the downspout or the water pipe, and as a result, the connection portion has to be damaged.

Therefore, as shown in FIG. 6, a drainage pipe cover for a gutter in which a lower end portion of a vertical gutter connecting tube capable of slidably fitting a vertical gutter is formed to form a water guiding tube connecting tube. Came to be used.

[Problems to be solved by the invention]

However, the water pipe that protrudes from the ground surface is buried when the rain gutter is constructed, and if it is larger than the diameter of the vertical gutter, there is no other way than to order another water pipe cover for the gutter.

In addition, since the conventional gutter drain pipe cover has a reduced diameter portion having a step portion bent at a right angle, when a large amount of rainwater flows in, turbulence occurs in the reduced diameter portion,
Not only does the drainage capacity decrease, but also adverse effects such as rainwater that accumulates in the reduced diameter portion overflowing from the connecting portion with the downspout occur, and further, the end of the water pipe appears at this connecting portion. This not only impairs aesthetics but also has problems such as damage to the end of the water pipe.

[Means for solving the problem]

The present invention has been devised in order to solve the above-mentioned drawbacks of the conventional product, and has a gutter connecting cylinder having a size such that a gap is formed such that air can escape between the gutter and a fitting gutter. A reduced diameter tube connected to the lower end of the downspout connection tube at an angle of inclination of 135 ° or more with respect to the wall surface of the downspout connection tube, and a water pipe connection tube connected to the free end of the reduced diameter tube And a gutter drain pipe cover formed with a decorative cover for covering the connection part of the water pipe connected to the water pipe connecting cylinder.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a gutter drain pipe cover of the present invention, FIG. 2 is a longitudinal sectional view of the same, FIG. 3 and FIG.
FIG. 5 is a diagram showing the state of use of the above, and FIG.

In the figure, reference numeral 1 denotes a downspout connecting tube provided for connection to the downspout A, which has a size such that a gap is formed between the downspout A and the downspout A in which air can escape. Things.

Reference numeral 2 denotes a diameter-reduced tube formed at the lower end of the downspout connection tube 1, which is reduced in diameter so as to have an inclination angle α of 135 ° or more with respect to the wall surface of the downspout connection tube 1. And
The inclination angle α is formed on both the inner peripheral surface and the outer peripheral surface.

Reference numeral 3 denotes a water pipe connecting tube formed at the lower end of the diameter-reduced cylinder 2, which is fitted into a connection portion of the water pipe B exposed on the ground surface, and reference numeral 4 denotes a water pipe. A decorative cover formed at the lower end of the downspout connection tube 1 so as to cover the connection portion of B, and is used for shielding the connection portion of the water pipe B.

In this embodiment, when the outer diameter of the water pipe B is substantially equal to the inner diameter of the water pipe connecting tube 3, the water pipe B is installed as shown in FIG. If it is larger, it is installed as shown in FIG. Adjustment of the water guide pipe B of the diameter reduction cylinder 2 in such a case is achieved by adjusting the height of the water guide pipe B already buried by cutting.

The downspout connection tube 1 is formed to be relatively long compared to the water pipe connection tube 3 so that it can slide upward along the downspout A even after connection to the downspout A. The downspout connection section 1 and the water pipe connection tube 3 are detachably connected to the downspout A and the water pipe B.

[Effect of the invention]

As is clear from the above, the drainage cover for gutter of the present invention is provided at the lower end portion of the gutter connection tube with respect to the wall surface of the gutter connection tube.
Since it is configured to form a water pipe connecting tube whose diameter is reduced through a diameter-reducing cylinder having an inclination angle of 5 ° or more, it can flexibly cope with any diameter of the water pipe, and water pipe construction This saves the labor of a gutter installation contractor who becomes a contractor after the contractor.

In addition, the present invention forms a gap between the downspout and the downspout connecting tube for the purpose of sliding and bleeding air, but there is no overflow caused by turbulence of rainwater due to diameter reduction seen in conventional products. Further, since a decorative cover is provided on the outer periphery of the connecting pipe of the water pipe to shield the connecting section of the water pipe, the connecting section of the water pipe is not damaged and the aesthetic appearance can be improved.
