Abstract

PROBLEM TO BE SOLVED: To provide an eaves gutter capable of reducing the quantity of rainwater flowing downward along an outer surface of a gutter front surface side wall, and securely preventing it from flowing to a bottom wall lower surface. SOLUTION: In an eaves gutter A comprising front and back surface side walls 1, 2, and a bottom wall 3, a middle part of the vertically raised gutter front surface side wall 1 is bent horizontally forward to form a swollen part bottom surface part 5 of a proper width, a front end edge part of the swollen part bottom surface part 5 is protruded in the form of an arc vertically downward, it is then raised vertically upward to form a swollen part front surface part 6, and form a drain edge part 7 at a lower end part of the swollen part front surface part 6, an upper end part of the gutter front surface side wall 1 is swollen forward to form a swollen part 4, and an upper end edge part of the swollen part 4 is bent to be down inclined toward the inside of the gutter A to form an inclined top surface part 8. More rainwater can thus be received by the inclined top surface part 8 to flow into the inside of the eaves gutter A. Rainwater flowing downward along the swollen part front surface part 6 can be securely cut off by the drain edge part 7 to drop.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter installed at an eave.

[0002]

2. Description of the Related Art An eaves gutter receives rainwater flowing down a roof surface and guides it to a vertical gutter. A part of the rainwater flowing down the roof surface adheres to the upper end of the front side wall of the eaves gutter. In some cases, the water flows down the outer surface of the front side wall, and further wraps around the lower surface of the bottom wall of the eaves gutter. The rainwater that stagnates on the bottom surface of the bottom wall takes in dust and dust in the air, and the dust and dust remain on the bottom surface of the bottom wall even after the rainwater evaporates, so that the bottom surface of the bottom wall is contaminated.

[0003] In order to solve the above problem, for example, as disclosed in Japanese Patent Application Laid-Open No. Hei 9-144250, as shown in FIG. The outer surface 51 of the gutter front side wall 51
The eaves gutter 50 has been devised so that the rainwater flowing down along the line a is drained at the lower end edge 52 so that the rainwater does not flow into the lower surface 53 of the gutter bottom wall.

[0004]

However, the above eaves gutter 50
When a large amount of rainwater flows down the roof surface due to a large amount of rainfall, the amount of rainwater flowing down the outer surface 51a of the gutter front side wall 51 also increases. Despite the formation of a drain, the rainwater sometimes reaches the bottom surface 53 of the gutter bottom wall.

In order to solve the above-mentioned problems, the present invention can reduce the amount of rainwater flowing down the outer surface of the front wall of the gutter and further reliably prevent the rainwater from flowing to the lower surface of the bottom wall. It will provide eaves gutters that can be used.

[0006]

[Means for Solving the Problems] To solve such problems,
According to the present invention, in an eave gutter having front and rear both side walls and a bottom wall, an upper end portion of a front side wall is swelled forward, and a drainage edge protruding downward is formed at a lower end of a front surface of the swelling portion. I decided that. Thereby, the rainwater flowing down the outer surface of the front side wall is drained at the drain edge formed at the lower end of the front surface of the bulging portion, and it is possible to reliably prevent rainwater from flowing to the lower surface of the bottom wall.

Further, according to the present invention, in an eaves gutter having front and rear both side walls and a bottom wall, an upper end portion of a front side wall is bulged forward, and an end of the bulged portion is lowered inside the eaves gutter. It was bent in an inclined manner to form an inclined top surface portion. Since the upper opening of the gutter can be widened by the formation of the bulging portion, and the upper surface portion is an inclined top surface portion,
Conventionally, rainwater attached to the upper end of the front side wall can be received by the inclined top surface and guided into the eaves gutter, and the amount of rainwater flowing down the outer surface of the front side wall can be reduced.

[0008] Throughout the specification, the front refers to a direction away from a building, and the rear refers to a direction approaching a building.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below based on examples. FIG. 1 is a perspective view of an eaves gutter A according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view of an example in which the eaves gutter A is installed at an eaves via a gutter gutter hanging tool.

The eaves gutter A of the present embodiment has front and rear side walls 1, 2
And a substantially U-shaped groove opening upward from the bottom wall 3 and
An upper end portion of the gutter front side wall 1 is swelled forward to form a swelling portion 4, and an upper edge of the swelling portion 4 is bent inward into the gutter so as to form an inclined top surface portion 8. A front engaging ear 9 that can be engaged with the engaging portion of the eave gutter hanging tool is formed at the distal end edge of the top surface 8, while the engaging portion of the eave gutter hanging tool is formed on the upper end edge of the gutter rear side wall 2. A rear engaging ear 10 that can be engaged is formed.

The bulging portion 4 is a vertically erected gutter front side wall 1.
Is bent horizontally forward to form a bulged portion bottom surface portion 5 having an appropriate width, and the front end edge of the bulged portion bottom portion 5 is vertically projected downwardly in an arc shape, and then vertically vertically upwardly. The bulging portion front portion 6 is formed by rising, and a drain edge 7 is formed at the lower end of the bulging portion front portion 6.

The eaves gutter A thus formed is, for example, shown in FIG.
As described above, if the bulge 4 is installed at the eaves via the eave gutter hanging tool B, the upper opening of the eave gutter A is widened due to the formation of the bulge 4, and the inclined top surface 8 of the bulge 4 is connected to the gutter. Since it is sloped down inside the gutter, it can receive more rainwater and flow it into the eaves gutter. In addition, the bulging part front part 6
The rainwater flowing down along the drain can be reliably separated and dropped by the drain edge 7, so that it is possible to prevent the rainwater from flowing to the lower surface of the bottom wall 3 of the eaves gutter A.

In the present invention, the bulging portion bottom portion 5
Is not limited to a horizontal plane such as the eaves gutter A, but is a flat surface inclined forward and downward as shown in FIG. 3 or a curved surface inclined downward and forward as shown in FIG. It can also be formed as In these cases, the lower end portion of the bulging portion front surface portion 6 can be made to project downward to form a draining edge portion without forming a downward projecting portion.

The bulging portion front portion 6 is formed so as to rise vertically upward like the eaves gutter A, and is formed to be inclined upward toward the inside of the eaves gutter (rear) as shown in FIG. Although not shown, it can also be formed in an upwardly inclined shape toward the outside (front) of the eaves gutter. Furthermore, when the bulging part front surface part 6 is formed in an inclined shape, it may be formed as a curved surface.

As shown in FIGS. 6A and 6B, the drain edge 7 is formed by protruding the tip edge of the bulging bottom surface 5 vertically downward like an arc like the eaves gutter A. 6 (c), a pentagonal shape as shown in FIG. 6 (d), or a bar-shaped projection as shown in FIG. 6 (e). You can also. May be implemented.

If the inclined top surface portion 8 is formed to be inclined downward toward the inside of the eaves gutter, it may be formed as a flat surface or a curved surface. May be either a top chord or a bottom chord in cross section.
