However, as described in each of the above-mentioned patent documents, the downspout cover is often provided integrally with the members forming the downspout. Therefore, the drop hole cover is likely to be restricted by the shape and size of the drop hole, and is likely to be a simple accessory to the member that constitutes the drop hole. etc. was difficult. For example, since the drop opening cover is a small dome-shaped one made by combining several vertical beams, it has low durability and tends to be clogged with dust and dead leaves.

Therefore, the main object of the present invention is to contribute to the improvement of the above-described problems.

In response to the above problems, the present invention
A downspout cover installed at the position of the downspout in the eaves gutter so as to cover the downspout,
A three-dimensional cover member is provided separately from the eaves gutter and the downspout, and the cover member has rigidity to withstand the load of people and accumulated snow, and keeps out dirt and dead leaves on the surface. The cover member has a large number of holes of a certain size, and the cover member has a flat upper surface and a side surface extending from the upper surface toward the bottom surface of the eaves gutter, and the side surface has an eaves edge side of the eaves gutter. A downspout spout cover is characterized having a first fixed portion secured to a riser and a second fixed portion secured to a roof tip.

According to the present invention, the durability and functions can be improved by the above configuration.
In addition, since the cover member has a flat upper surface and a side surface extending toward the bottom surface of the eaves gutter, even if a person accidentally steps on the cover member during work, the flat upper surface provides stability. It is possible to ride in a state where it is folded down, and it is possible to prevent deformation and damage to the upper surface due to the load. The cover member can be fixed inside the eaves gutter by the first fixing part and the second fixing part.

The decorative member 37 is an elongated member for covering the portion of the roof 2 on the eaves 3 side, the eaves gutter 21, etc., and adjusting the appearance of the roof 2. - 特許庁The decorative member 37 has a cross-sectional shape that extends substantially vertically. When the position of the upper end is reached, the upper end of the rising portion 21b is pressed from above.

In addition to the above configuration, the drop opening cover 25 of this embodiment can have the following configuration.

(1) The drop cover 25 has a three-dimensional cover member 41 that is separate from the eaves gutter 21 and downpipe 22 .
The cover member 41 is rigid enough to withstand the load of people and accumulated snow, and has a large number of holes 42 on its surface that are large enough to prevent dust and dead leaves from passing through.

Here, the cover member 41 is a member that constitutes the main part of the drop opening cover 25 . Usually, the cover member 41 is often integrated with the members forming the drop opening 24 and attached to the eaves gutter 21 or the downpipe 22. , the cover member 41 is constructed as a separate part from any of the members constituting the eaves gutter 21, the downspout 22, and the drop opening 24. As shown in FIG. The cover member 41 is independently installed inside the eaves gutter 21 in a state separated from the members forming the drop opening 24.例文帳に追加

The three-dimensional shape may be of any shape, but at least the cover member 41 has a shape larger than the opening 21d of the drop opening 24 by one size or more when viewed in plan, so that the entire drop opening 24 is covered. is assumed to surround from the outside. In addition, it is preferable that the cover member 41 has approximately the same height dimension as the eaves gutter 21 when viewed from the side. In this embodiment, the cover member 41 is slightly higher than the upper surface of the roof 2 and slightly lower than the upright portion 21b on the eaves 3 side. As a result, the cover member 41 can drain rainwater up to a height at which the eaves gutter 21 overflows. However, the height of the cover member 41 is not limited to this.

Rigidity to the extent that it can withstand loads from people and accumulated snow can be obtained by making the cover member 41, for example, made of metal or high-strength resin. Also, by devising the shape of the cover member 41, the rigidity can be ensured. For example, by forming the cover member 41 into a polyhedral shape or the like, it is possible to obtain higher rigidity than the existing dome-shaped one.

The surface is a surface forming the appearance of the cover member 41 .

The hole portion 42 may have any size as long as it is a size that does not allow dust and dead leaves to pass through. For example, the hole 42 can have a size of about 0.5 mm to 1.5 mm. In this embodiment, the holes 42 are square holes or the like arranged in a grid orderly at equal pitches in the vertical and horizontal directions. The holes 42 are provided substantially evenly over substantially the entire surface of the cover member 41 .

(2) The cover member 41 may have a flat upper surface 51 and side surfaces 52 to 55 extending from the upper surface 51 toward the bottom surface 21 a of the eaves gutter 21 .
The side surfaces 52 to 55 have a first fixing portion 56 fixed to the rising portion 21b on the eaves edge 3 side of the eaves gutter 21 and a second fixing portion 57 fixed to the tip portion of the roof 2. You can

Here, the upper surface 51 of the cover member 41 is a generally flat horizontal surface. The upper surface 51 is substantially rectangular (square or rectangular) in plan view. An upper surface 51 having a substantially rectangular shape in plan view is surrounded by four sides, a pair of sides substantially parallel to the longitudinal direction L of the eaves gutter 21 and a pair of sides substantially parallel to the width direction W of the eaves gutter 21. It is a face.

The side surfaces 52 to 55 of the cover member 41 are composed of four substantially rectangular (square or rectangular) surfaces extending substantially downward from respective sides forming the substantially rectangular upper surface 51 when viewed from above. Each of the four sides 52-55 is generally flat and substantially vertical. The four side surfaces 52 to 55 and the top surface 51 make the cover member 41 substantially rectangular parallelepiped or cubic with an open bottom.

The first fixing portion 56 includes a cover fixing portion 56a that extends substantially vertically along the side surface 52 of the cover member 41 on the side of the eaves 3, and a gutter that extends substantially vertically along the rising portion 21b of the eaves gutter 21 on the side of the eaves 3.

It is The cover fixing portion 56a is fixed in advance to the side surface 52 of the cover member 41 on the eaves edge 3 side, and the gutter mounting portion 56b is fixed to the rising portion 21b of the eaves gutter 21 on the eaves edge 3 side by a fastener such as a screw or a rivet. be done.

The second fixing portion 57 includes a cover fixing portion 57a that extends substantially vertically along the side surface 53 on the eaves side of the cover member 41, and a lower surface ( or upper surface), and has a roof mounting portion 57b extending laterally in a substantially horizontal state. The cover fixing portion 57a is fixed in advance to the side surface 53 of the eaves side of the cover member 41, and the roof mounting portion 57b is screwed to the lower surface (or upper surface) of the tip portion of the roof material 19 from below (or above). It is fixed by a fixture 59 such as a rivet or the like.

(3) The cover member 41 may have a convex portion 61 that rises with respect to the hole portion 42 on its surface.

Here, the surface on which the hole 42 is formed can be any of the surfaces (the upper surface 51 and the four side surfaces 52 to 55) constituting the cover member 41, but in this embodiment, at least the upper surface 51 and , two side surfaces 54 and 55 located on both sides of the eaves gutter 21 in the longitudinal direction L.

The convex portion 61 may have any shape as long as it has a shape that rises in the out-of-plane direction with respect to the hole portion 42. In this embodiment, for example, it has two orthogonal surfaces. By attaching one surface of the angle member 62 having an L-shaped cross section to the surface of the cover member 41 as the mounting surface 63 , the remaining surface of the angle member 62 is used as the convex portion 61 . A single or a plurality of angle members 62 can be attached to each surface on which the convex portion 61 is provided. The plurality of angle members 62 are preferably installed in parallel with intervals. By using the angle member 62 , the convex portion 61 becomes continuous along the mounting direction of the angle member 62 .

Specifically, the angle member 62 faces the upper surface 51 of the cover member 41 in the longitudinal direction L of the eaves gutter 21 and has substantially the same length in the longitudinal direction L as the upper surface 51 . It is attached in a state that it is almost aligned with 51. In this case, the angle member 62 is attached at a position between rows of the holes 42 formed in the upper surface 51 in such a manner as not to block the holes 42 as much as possible. The row of holes 42 is provided in the direction along the side of the upper surface 51 .

The angle member 62 extends in the vertical direction with respect to the two side surfaces 54 and 55 of the cover member 41 and has substantially the same length in the vertical direction as the side surfaces 52 to 55. It can be installed in almost the same state. In this case, the angle member 62 is attached at a position between the rows of the holes 42 formed in the side surfaces 54 and 55 so as not to block the holes 42 as much as possible. The rows of the holes 42 are provided along the sides of the side surfaces 54 and 55 .

<Action> The action of this embodiment will be described below.

Rainwater falling on the roof 2 flows down along the slope of the roof 2 to the side of the eaves 3 and is collected from the eaves 3 to an eaves gutter 21 attached to the eaves 3 of the roof 2.例文帳に追加The rainwater collected in the eaves gutter 21 is flowed downstream along the drainage gradient of the eaves gutter 21, and is discharged to the outside through the downpipe 22 from the drop opening 24 provided on the downstream side of the eaves gutter 21. - 特許庁.

For example, when the upper part of the eaves gutter 21 is open and exposed to the outside, dust and dead leaves around the roof 2 may enter the inside of the eaves gutter 21 due to wind or the like. When the debris and dry leaves are sufficiently small relative to the drop opening 24, they are flushed from the drop opening 24 to the downspout 22 together with the rainwater. There is a risk that the water will collect in the water or clog the drop opening 24 or the downpipe 22, thereby hindering the drainage from the downpipe 22. - 特許庁Therefore, a drop hole cover 25 is provided on the drop hole 24 to prevent clogging of the drop hole 24 and the like with dust and dead leaves.

<Effects> According to this embodiment, the following effects can be obtained.

(Effect 1) The drop opening cover 25 of the downspout 22 may include a three-dimensional cover member 41 configured as a separate part from the eaves gutter 21 and the downspout 22 . As a result, the cover member 41 is not restricted by the shape and size of the drop opening 24 itself, so that the cover member 41 can be designed with a relatively free structure and size. Therefore, it is possible to further enhance the functions of the outlet cover 25 (for example, the drainage function and the clogging prevention function). Also, the cover member 41, which is a separate part, can be installed on the drop opening 24 of the downpipe 22 by retrofitting or the like as required.

By forming the cover member 41 into a three-dimensional shape, the drop opening 24 of the downpipe 22 can be three-dimensionally covered. As a result, the cover member 41 can be made less likely to be clogged with dust or dead leaves.

The three-dimensional cover member 41 may have a rigidity capable of withstanding the load of a person and accumulated snow. This makes it difficult for the cover member 41 to deform and ensures high durability.

The cover member 41 may have a large number of holes 42 on the surface that are large enough to prevent dirt and dead leaves from passing through. This allows the cover member 41 to drain rainwater from the spout 24 to the downpipe 22 through any one of the many holes 42 while keeping out dirt and dead leaves.

(Effect 2) The drop opening cover 25 of the downspout 22 may have the flat upper surface 51 of the cover member 41 and the side surfaces 52 to 55 extending toward the bottom surface 21 a of the eaves gutter 21 . As a result, even if a person steps on the cover member 41 carelessly during work, the flat upper surface 51 allows a person to get on in a stable state. At this time, for example, by setting the flat upper surface 51 to substantially the same height as the roof material 19 , it is possible to make it difficult to trip over the cover member 41 .

The flat upper surface 51 is supported by the side surfaces 52 to 55 extending from the upper surface 51 toward the bottom surface 21a of the eaves gutter 21, thereby providing the flat upper surface 51 with rigidity capable of withstanding the load of people and accumulated snow. becomes possible. Therefore, deformation and breakage of the upper surface 51 and the like due to the load can be prevented.

Further, the side surfaces 52 to 55 of the cover member 41 may be provided with the first fixing portion 56 and the second fixing portion 57 (integrally). As a result, the first fixing portion 56 fixed to the rising portion 21b of the eaves gutter 21 on the side of the eaves edge 3 and the second fixing portion 57 fixed to the tip portion of the roof 2 allow the cover member 41 to be secured to the eaves gutter. 21 can be fixed inside. Therefore, even if the cover member 41 is configured as a separate component, the cover member 41 can be reliably installed and held at the position of the drop opening 24 of the downspout 22 .

(Effect 3) The outlet cover 25 of the downspout 22 may have a convex portion 61 on the surface of the cover member 41 that rises with respect to the hole portion 42 . As a result, the dust and dead leaves that have reached the hole 42 are lifted off the surface on which the hole 42 is formed by the convex portion 61, so that the dust and dead leaves adhere to the surface on which the hole 42 is formed. It is possible to prevent clogging (clogging) of the hole 42 and to ensure drainage from the hole 42 at all times.
