Description

[Detailed description of the invention] The present invention relates to rain gutters used as construction materials.

Conventionally, as this type of rain gutter, a gutter whose cross-sectional shape is a precise semicircular arc is often used.

However, in the case of such round gutters, the curvature of the inner surface is set to be relatively large in order to ensure drainage performance above a certain capacity, so if the amount of rainwater flowing in is small, the water level becomes lower. Therefore, in order to ensure reliable drainage of even a small amount of rainwater, it is necessary to construct the system with a certain flow gradient. However, even if this is done, if the flow gradient is small, garbage that flows in with rainwater will likely accumulate, so in order to avoid this, it is recommended to provide a flow gradient that is clearly visible during actual construction. I'm forced to.

On the other hand, there is a demand among rain gutter builders to make rain gutters invisible from the outside, and in order to meet this demand, the so-called fascia is used to hide the entire length and height of the conventional round gutter mentioned above. It is conceivable to hold the decorative board in a separate frame. However, if this is done, it is necessary to provide a frame for attaching the decorative board in addition to constructing the rain gutter, and the troublesome work and effort involved is a great burden on the constructor.

This idea was made in view of the above circumstances.
By housing the rain gutter body with a predetermined cross-sectional shape in a frame body equipped with a decorative board, construction is easy and can be installed without tilting the decorative board, and even in such construction conditions, the amount of rainwater is The purpose is to provide a rain gutter that does not easily accumulate garbage, etc., regardless of the amount.

Hereinafter, the rain gutter of the present invention will be explained according to the illustrated embodiment.

As is clear from the example shown in Figure 1,
The rain gutter 100 has the entire length of the rain gutter body 2 inside the frame 1.
3 so that the entire height part elastically engages to form a half-egg shape.
It is housed with point support. In the frame 1, a decorative board 12 is raised up from one end in the width direction of a flat bottom plate 11, and a semi-cylindrical engagement part 121 is provided at the upper end of the decorative board 12. Further, a support plate 13 is raised at the opposite end, and a semi-cylindrical engagement portion 131 is also provided at the upper end of this support plate 13.

Although such a frame 1 can be constructed by bending a thin metal plate, it is also possible to construct a continuous molded product obtained by continuously extruding thermoplastic synthetic resin, such as polyvinyl chloride, from an extrusion die. It can also be constructed by dividing into predetermined lengths. The latter, made of synthetic resin molded products, is superior to the former, made of metal, in terms of corrosion resistance and elastic restoring force, and is convenient to handle due to its light weight.

Next, as clearly shown in FIG. 2, the rain gutter main body 2 has a semi-oval cross-sectional shape, and the curvature of its inner surface gradually decreases as it approaches the bottom 22. Further, the rain gutter main body 2 is provided with ears 21, 21 extending over the entire length at both ends thereof. In this type of rain gutter body 2, the passage width near the lowest point is narrower than that of a semi-circular round gutter with the same width, so even if a small amount of rainwater flows in, the water level will be high compared to the amount of water. ,
Rainwater flows at a relatively high velocity. Therefore, even if the flow gradient that should be applied during construction is made so small that it cannot be seen, or in extreme cases, even if the construction is done horizontally, a good drainage effect will be maintained, making it difficult for garbage to accumulate. becomes. It goes without saying that the rain gutter main body 2 is provided with a rainwater outlet at an appropriate location.

As shown in detail in FIG.
1,131 are the two ears 21, 21 of the rain gutter body 2
The entire length of the bottom part 22 of the rain gutter body 2 comes into elastic contact with the bottom plate 11 of the frame body 1, and the frame body 1 and the rain gutter body 2 are elastically engaged at these three points. supported and integrated. In this state, frame 1
The bottom plate 11, the decorative plate 12, and the support plate 13 are in a state where they are somewhat expanded against their elasticity, while the rain gutter body 2 is in a state where it is somewhat narrowed against their elasticity. As a result, a phenomenon in which the two are pressed against each other occurs, and a reliable engagement state is obtained.

In such a rain gutter 100, as described above, even if the rain gutter main body 2 is constructed horizontally or with a flow gradient that is not visible, a good drainage effect is maintained. The decorative board 12 that hides the rain gutter body 2 is installed horizontally or tilted to such an extent that it cannot be seen. Therefore, it becomes possible to meet the request of the construction owner to construct the rain gutter body, that is, the rain gutter so that it cannot be seen from the outside. In addition, the half-egg-shaped rain gutter body 2 as shown in Figure 2 is different in shape from the conventional semi-circular arc-shaped rain gutter, so the orderer may feel that it is strange. Since the full length and full height portion of 2 is accommodated in the frame 1, it is not visible from the outside, and no problem arises due to such discomfort.

FIG. 3 shows a rain gutter 100 in which the decorative board 12 is made taller than the support board 13. According to this, the upwardly protruding portion 122 of the engaging portion 121 in the decorative board 12 plays the same role as a splash-preventing decorative plate provided at a location where a gutter joins the rain gutter main body 2, and prevents rainwater from flowing. This has the advantage of preventing scattering to the outside.

By the way, in the case of general rain gutters, a decorative plate may be attached as mentioned above, but since this decorative plate is partially attached at the meeting point of the rain gutter, this decorative plate is This is essentially different from the protruding portion 122 described in FIG. That is, since the protruding portion 122 originally constitutes a part of the decorative board 12, it is not a partial portion.
It is arranged over the entire length of the rain gutter body 2.

As detailed above, according to the rain gutter of the present invention, the rain gutter body is completely hidden by the frame, so even if the rain gutter body is housed in a half-oval shape, after construction, Only the decorative board on the frame is visible, and the eaves can be decorated in the same way as conventional decorative boards attached separately. Further, even if the frame body and the rain gutter body are separate bodies, by housing the rain gutter body within the frame body, it is only necessary to attach the frame body to the eaves, which simplifies the installation work. Further, the rain gutter main body is elastically supported by the frame in a three-point support state, and is securely engaged by pressing between the two, allowing for long-term use. Furthermore, since the gutter body is housed in a half-egg shape,
Rainwater flows down smoothly and sand, dirt, etc. do not accumulate, so the rain gutter can be constructed horizontally, and the decorative board can be made in perfect harmony with the horizontal eaves.
