[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eaves trough cover that suppresses the intrusion of a water blocking object into the water channel of the eaves trough that collects and drains rainwater that flows down from the roof.

[0002]

[Prior art]

 FIG. 5 is a perspective view showing a configuration of an example of a conventional eaves gutter, which is disclosed in Japanese Utility Model Laid-Open No. 57-168629. As shown in FIG. 5, the eaves gutter is composed of an outer gutter 2 having a substantially concave cross section and an inner gutter 1 having a substantially V-shaped cross section and internally provided in the outer gutter 2. There is. A large number of elongated holes 4 are formed on the surface of the inner gutter 1.

There is also an eaves gutter disclosed in, for example, Japanese Utility Model Laid-Open No. 52-147932, in which the cross section of each of the outer gutter 2 and the inner gutter 1 is formed in a substantially arc shape. Further, the hole 4 formed on the surface of the inner gutter 1 may have a substantially circular shape.

In the conventional eaves gutter shown in FIG. 5, rainwater that has flowed down the inner gutter 1 flows down from the hole 4 to the outer gutter 2 and flows in the outer gutter 2 in a predetermined direction to be drained. When fallen leaves and the like enter the inner gutter 1, they are collected in the bottom portion 5 of the inner gutter 1 and do not enter the outer gutter 2 side. For this reason, in such eaves gutter, there is an advantage that the water flow is not hindered by the invasion of fallen leaves.

[0005]

[Problems to be solved by the device]

 However, in the conventional eaves trough described above, when a large amount of fallen leaves and the like accumulate in the inner gutter 1, the hole 4 is blocked, and rainwater overflows from the inner gutter 1 without flowing down from the hole 4 to the outer gutter 2. There was a chance to meet.

Therefore, it has been necessary to regularly remove fallen leaves and the like accumulated in the inner gutter 1 and clean the eaves gutter. However, the fallen leaves accumulated in the inner gutter 1 had only to be removed by climbing on the roof and using a broom, etc., and it had to be a dangerous and difficult work.

In the eaves gutter disclosed in Japanese Utility Model Laid-Open No. 52-147932, the inner gutter 1 is rotatably attached with one outer edge of the outer gutter 2 as a fulcrum. Since 1 can be rotated to be arranged outside the outer gutter 2, it is possible to remove the fallen leaves and the like accumulated in the inner gutter 1. However, providing such a mechanism on the eaves was expensive.

The present invention has been made to solve the above-mentioned problems, and it is possible to suppress the accumulation of fallen leaves and the like in eaves gutters, and to maintain good drainage of rainwater. Intended to provide a cover.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first solution of the eaves trough cover according to the present invention is to cover the eaves trough (10) having a water channel part with an opening formed at the upper side, and to supply water to the water channel part. An eaves trough cover (20) for suppressing the intrusion of an obstruction, which is inclined from the upper side of the end of the opening to the lower side of the inner peripheral wall of one end of the water channel of the eaves gutter. A base (21) having a rainwater receiving surface arranged to receive the rainwater and covering the opening of the eaves gutter, and the rainwater on the rainwater receiving surface formed on or near the lower end of the base. And a drainage port (21a) flowing down into the water channel part.

A second solving means of the eaves trough cover is a holding member which is fixed to the base and holds the base on the eaves trough by engaging with an end of at least one opening of the eaves gutter. (22) is provided.

[0011]

In the first solution of the eaves gutter cover, the base body is arranged so as to cover the upper part of the opening of the eaves gutter. When the rainwater falls on the rainwater receiving surface of the base body, it flows on the rainwater receiving surface and flows down from the drain port of the base body to the water channel of the eaves gutter. Therefore, it is possible to suppress the entry of the water flow obstruction into the eaves gutter. Moreover, since most of the base is located at a position higher than the upper end of the eaves gutter, the ventilation on the base 21 is good, and even if the water blocking substance collects on the base (rainwater receiving surface). , They can be scattered using wind power.

In the second solution of the eaves gutter cover, the base body is attached to the eaves gutter by the holding member. Therefore, the base can be detachably attached to the existing eaves gutter.

【Example】

 An embodiment of an eaves gutter cover according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the structure of an embodiment of an eaves trough cover according to the present invention attached to an eaves trough. FIG. 2 shows a plan view ((a) in the figure) and a side view ((b) in the figure) of FIG. Here, the eaves gutter shown in the embodiment is an example of a conventional eaves gutter.

As shown in FIG. 1, the eaves gutter 10 has an opening 11 formed on the upper side thereof and a water channel portion 12 having a substantially arcuate cross section. The eaves gutter 10 is formed of, for example, a plate-shaped member having a thickness of about 0.5 mm. Both ends of the opening 11 of the eaves gutter 10 are formed in a substantially hollow cylindrical shape.

The eaves gutter cover 20 includes a base body 21 and a holding member 22. The base 21 is formed of, for example, a steel plate having a thickness of about 0.5 mm, preferably a stainless steel plate having excellent corrosion resistance, or a plastic member. The length of the base 21 in the longitudinal direction is, for example, about 1.2 m. As shown in FIG. 1 and FIG. 2B, the base body 21 is formed in a substantially L shape or a substantially V shape. Further, as shown in FIG. 2A, drain ports 21a, which are cut out in a substantially arc shape, are arranged in parallel at one end thereof with a predetermined interval.

The holding member 22 is made of, for example, a stainless steel plate having a thickness of about 0.7 mm and having elasticity, a plastic member, or the like. As shown in FIG. 2 (b), the holding member 22 has a central portion formed in a substantially hollow cylindrical shape, and both sides thereof are extended in a substantially vertical direction. One end surface of the holding member 22 is fixed to the base body 21. As a method of fixing the holding member 22 to the base body 21, for example, any method such as welding, adhesion, screwing with a screw, or the like may be used. Although only one holding member 22 is provided on the base body 21 in FIG. 2A, a plurality of holding members 22 may be provided, for example, at predetermined intervals in the longitudinal direction of the base body 21.

Next, how the eaves gutter cover 20 is attached to the eaves gutter 10 will be described. As shown in FIG. 2 (b), the portion of the holding member 22 formed into a substantially hollow cylindrical shape is replaced with the substantially cylindrical portion of one end of the eaves gutter 10 (left side in FIG. 2 (b)). Mating. As a result, the end surface of the holding member 22 extending downward in FIG. 2B is brought into contact with or pressed against the outer wall surface of the eaves gutter 10. As a result, the base 21 is held on the eaves gutter 10.

At this time, one end portion (right side in FIG. 2B) of the base 21 comes into contact with the upper end portion of the eaves gutter 10 on the right side in the figure. Further, the other end of the base 21 (on the left side in FIG. 2B) comes into contact with the inner peripheral wall surface of the water channel 12 of the eaves gutter 10 and slightly below the upper left end in the figure. In this way, the surface of the base body 21 arranged so as to incline from the opening 11 of the eaves trough 10 to the upper left side in the figure of the water channel 12 of the eaves trough 10 serves as a rainwater receiving surface for receiving rainwater. Become. A plurality of bases 21 overlap each other in the longitudinal direction by, for example, about 10 mm, and are connected to the eaves gutter 10.

FIG. 3 is a side view showing the flow of rainwater on the eaves gutter cover 20 attached to the eaves gutter 10 described above. As shown in FIG. 3, in the eaves gutter cover 20, the rainwater receiving surface of the base 21 is located below the end of the roof 30 of the building, and the downward direction of the rainwater receiving surface of the base 21 is the roof 30 or the like. Is arranged so as to be an outer side direction (left direction in FIG. 3).

When the rainwater flows down from the roof 30 or the like, the rainwater flows down in the direction A in the figure and falls on the rainwater receiving surface of the base body 21. Therefore, the rainwater does not flow down directly into the water channel 12 of the eaves gutter 10. The rainwater flows down to the lower left side in the figure (direction B in the figure) due to the downward gradient of the rainwater receiving surface of the base body 21. Since the drain 21a is formed at the lower left end of the base body 21 in the figure, rainwater passes through the drain 21a and flows down into the water channel 12 of the eaves gutter 10 (direction C in the figure). .

Since the upper part of the opening 11 of the eaves gutter 10 is covered with the base 21, the water flow obstruction, such as litter, must be of a size that can pass through the drain 21a. , Does not enter the waterway 12 of the eaves gutter 10. Also, soil, dust, and cypress leaf-sized ones can pass through this drainage port 21a, but they flow with rainwater through the water channel portion 21 of the eaves gutter 10 and are drained. It does not prevent water flow.

Further, since most of the base 21 is disposed above the opening 11 of the eaves gutter 10, when fallen leaves or the like adhere to the rainwater receiving surface of the base 21, when the wind blows. These winds can be used to naturally disperse these things. In addition, when fallen leaves and the like stick to the base 21 and are not scattered, it is easy to use these by spraying water or air onto the rainwater receiving surface of the base 21 using an injector or the like. Can be scattered. At this time, these things can be scattered without the above injection from the roof of the building.

Next, a specific design example of the eaves gutter cover 20 according to the present invention will be shown. FIG. 4 is a diagram showing a design example of the eaves gutter 10 and the eaves gutter cover 20 shown in FIG. As shown in FIG. 4 (b), the eaves gutter 10 has a thickness T1 of 0.5 mm, an inner radius R1 forming the water channel portion of 45 mm, a lateral width L1 of 90 mm, and outer diameters of hollow cylindrical portions at both ends. D1 is set to 8 mm.

At this time, in the eaves gutter cover 20, as shown in FIG. 4A, the interval L11 forming the drainage port 21a was set to 15 mm, and the semicircular cutout radius R11 was set to 2.5 mm. . Further, as shown in FIG. 4 (b), the thickness T11 of the base 21 was set to 0.5 mm, the length L12 of the portion constituting the rainwater receiving surface was set to 83 mm, and the other length L13 was set to 22 mm. The height H11 of the base 21 from the upper end of the eaves gutter 10 (that is, the center of the half-diameter R1 of the water channel of the eaves gutter 10) is set to 17 mm, and the height of the holding member 22 from the close contact surface with the base 21 of the eaves gutter 10 is increased. The height H12 to the upper end was set to 10 mm.

An embodiment of the eaves gutter cover according to the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. It is possible. For example, the holding member 22 is attached to one end portion of the base body 21, but may be attached to both end portions and engaged with both end portions of the eaves gutter 10. Further, although the base 21 is attached to the eaves gutter 10 only by the holding member 22, if the base 21 is attached to the eaves gutter 10 and a wire or the like is further wound, the base 21 can be more securely fixed. .

The drainage port 21a is formed by cutting out the outer edge portion of the base body 21 in a substantially arc shape. However, the drainage port 21a is not limited to this, and the vicinity of the outer edge portion of the base body 21 is opened in a substantially circular shape, a substantially square shape, or the like. It may be formed. Further, in the embodiment, the base 21 is attached to the eaves gutter 10 so as not to move, but the base 21 may be formed with the holding member 22 so as to be rotatable around one end of the eaves gutter 10 as a fulcrum. The height of the rainwater receiving surface of the base 21 from the eaves gutter, the angle of inclination, the size of the area, and the number, shape, area, etc. of the drainage ports 21a should be appropriately determined according to the difference in environment such as precipitation. They can be set and are not limiting in size in the present invention.
