[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves gutter joint provided with a drain outlet.

[0002]

2. Description of the Related Art Conventionally, various types of eaves gutter joints having a drain port are known, but the most general eaves gutter joint having a drain port is disclosed in Japanese Patent Publication No. 59-4049.
As described in Japanese Unexamined Patent Application Publication No. 6-206, a long piece having a groove-shaped cross section is bent at a predetermined angle, and a drain port is provided at a substantially central portion of the bent portion. This eaves gutter joint is used by applying adhesive to both ends of the eaves gutter joint and the ends of the eaves gutter, and gluing the ends of the eaves gutter and the ends of the eaves gutter joint to drain. Attach a downspout to the mouth. In this method, the eaves bend joint and the eaves gutter are firmly fixed with an adhesive.

[0003]

[Problems to be solved by the invention] However, if the eaves gutter and the eaves gutter bent joint are firmly fixed with an adhesive as described above, the eaves gutter expands in summer and shrinks in winter. The eaves gutter is pushed and pulled at the bent portion of the eaves gutter joint by the expansion and contraction of the eaves gutter. As a result,
There is a problem that force concentrates on this bent portion and the eaves gutter bending joint is damaged.

Accordingly, an object of the present invention is to provide a bent joint of an eaves gutter which is not damaged by expansion and contraction due to a temperature difference between summer and winter.

[0005]

According to the first aspect of the present invention, there is provided an eaves gutter bent joint in which a long piece of a groove having a cross section is bent at a predetermined angle, and the upper end of the bent portion is provided at an inner upper end . A drain port made of an elastic body is provided integrally from the outer upper end to a portion beyond the center, and a portion extending from the upper edge of the drain port to the inner upper end or the outer upper end is bent. The drain port is formed of the same elastic body.

[0006]

In the bent joint of the present invention according to the first aspect, a drain port made of an elastic body is provided integrally from the inner upper end or the outer upper end of the bent portion to a portion beyond the center, Since the part extending from the upper edge of the drain to the inner upper end or the outer upper end is formed of the same elastic body as the drain, the compressive force is applied to the eaves gutter joint by, for example, expansion and contraction of the eaves gutter. Alternatively, even if a tensile force acts, the compressive force or the tensile force is reduced by the elastic drain port and the inside of the corner from the upper edge of the drain port.
Portion reaches the upper end, or discharge port and the drain port will be absorbed alleviated by the compression deformation and tensile deformation of the portion extending outside the upper end of the outer corner side from the top edge of an elastic. For this reason, even if the eaves gutter is fixed to both ends of the eaves gutter joint with an adhesive, breakage of the eaves gutter bent joint due to expansion and contraction of the eaves gutter can be prevented.

[0007] Even if the eaves gutter bending joint is displaced in the horizontal direction due to expansion and contraction of the eaves gutter, the amount of the displacement is absorbed by deformation of the drainage port, which is an elastic body. The connection with the gutter is not damaged.

[0008]

Next, an embodiment of the present invention will be described. FIG. 1 shows an embodiment of the eaves bend joint of the present invention, and is an explanatory view showing a state where the eaves gutter is connected by the eaves bend joint.

In FIG. 1, reference numeral 1 denotes an eave trough made of a long body having a semicircular cross section made of a vinyl chloride resin. Thick ears 11, 11 are provided at upper ends on both sides of the eaves gutter 1. 2
Is an eaves bent joint made of vinyl chloride resin, and the eaves bent joint 2 is formed by bending a long piece of a groove-shaped cross section at substantially a right angle. A connecting portion 22 and an ear holding portion 23 are provided at both ends of the eave bending joint 2. Connection pieces 21, 21 into which the ends of the eaves gutter 1 are inserted are provided on the inner surface at the back of both connection parts 22. The ear holding portions 23 are provided at upper ends on both sides , and are engaged with the ear portions 11 of the eaves gutter 1. Reference numeral 3 denotes a drain port made of an elastic body made of synthetic rubber, and is provided integrally with the bent portion of the eaves gutter joint 2. In this case, the drainage port 3 is provided from the inner upper end 25 on the entry corner side of the eaves bend joint 2 to a portion beyond the center. The portions 24, 24 extending from the upper end edge of the drain port 3 to the inner upper end 25 on the entry corner side of the bent portion are also formed of the same elastic body as the drain port 3. 4 is a downspout.

Next, the eaves gutters 1 and 1 are connected to the eaves gutter joint 2.
A method and an operation of connecting are described. An adhesive is applied to the inner peripheral surfaces of the connecting portions 22 and 22 at both ends of the eaves gutter joint 2 and the outer peripheral surface of the ends of the eaves gutter 4, and the ends of the eaves gutter 4 are inserted into the connection pieces 21 while abutting the two. The ear 11 is fitted to the ear holding part 23. When this adhesive is solidified, the eaves gutter 1 and the eaves gutter bending joint 2 are firmly bonded. Then, the upper end of the downspout 4 is connected to the lower end of the drain port 3. In this way, the connection between the eaves gutters 1, 1 and the gutters 4 is completed.

In summer, when the eaves gutters 1 and 1 on both sides are extended, the corners of the eaves gutter joint 2 are pushed out from both sides, and a compressive force acts in a direction in which the angle of the bent portion becomes narrower. This eaves gutter joint 2 has an inner upper end on the inside corner side.
Elastic drain port 3 from 25 to the part beyond the center
Are provided, and the portions 24, 24 extending from the upper end edge of the drain port 3 to the inner upper end 25 on the inside corner of the bent portion are also made of an elastic body, so that they act on the eaves gutter bending joint. Since the bending compressive force is absorbed by the compression deformation of the drain port 3 and the portions 24 connected to and above the drain port 3, the eaves gutter bending joint 2 is not damaged.

Since the width of the non- elastic portion between the drain port 3 and the outer upper end 26 is short, the amount of expansion and contraction is small, and therefore, this portion is not damaged.
Conversely, when the eaves gutters 1 and 1 on both sides shrink in winter, both ends of the eaves gutter joint 2 are pulled, and a tensile force acts in a direction in which the angle of the bent portion increases. As described above, the eaves bend joint 2 has an inner corner on its inside corner side.
The drainage port 3 having elasticity is provided from the upper end 25 to a portion beyond the center, and furthermore, portions 24, 24 extending from the upper end edge of the drainage opening 3 to the inner upper end 25 of the bent corner.
Is also made of an elastic body, the bending tensile force acting on the eaves bend joint is absorbed by the tensile deformation of the drain port 3 and the portions 24, 24 connected above the drain port 3. The eaves bend joint 2 is not damaged.

FIG. 2 is an explanatory view showing a second embodiment of the present invention together with a use state. This embodiment is basically the same as the first embodiment except that a drain port 3a made of an elastic body of the eaves bent joint 2a is provided at a portion beyond the center from the outer upper end . As shown in FIG. 2, the drainage port 3 a is provided from the outer upper end 26 a on the protruding corner side of the eaves bent joint 2 to a portion beyond the center. Portions 24a, 24a extending from the upper end edge of the drain port 3a to the outer upper end 26a on the protruding corner side of the bent portion are also formed of the same elastic body as the drain port 3a. 4a is a downspout.

The eaves gutters 1a, 1a and the downspout 4a are connected by using the eaves gutter joint 2a by the same operation as the embodiment shown in FIG.

In summer, when the eaves gutters 1a and 1a on both sides are extended, the corners of the eaves gutter joint 2a are pushed out from both sides, and a compressive force acts in a direction in which the angle of the bent portion becomes smaller. The eaves bend joint 2a is provided with a drainage port 3a having elasticity from the outer upper end 26a on the protruding corner side to a portion beyond the center, and furthermore, the bent part from the upper end edge of the drainage port 3a is provided. Since the portions 24a, 24a reaching the outer upper end 26a on the corner side are also formed of an elastic body, the bending compressive force acting on the eaves gutter bending joint 2a is connected to the drain port 3 and the drain port 3 above. Part 24, 2
4, the eaves gutter bending joint 2a is not damaged.

Conversely, when the eaves gutters 1a, 1a on both sides shrink in winter, both ends of the eaves gutter joint 2a are pulled, and a tensile force acts in a direction in which the angle of the bent portion increases. However, as described above, the eaves gutter bending joint 2a has:
A drain port 3a having elasticity is provided from the outer upper end 26a on the outgoing corner side to a portion beyond the center, and the outer upper end 2 on the outgoing corner side of a portion bent from the upper edge of the outlet port 3a.
Since the parts 24a, 24a reaching 6a are also made of an elastic body, the bending tensile force acting on the eaves bend joint 2a exerts the drainage ports 3a and the parts 24a, 24a connected above the drainage ports 3a. Is absorbed by the compression deformation, so that the eaves gutter joint 2a is not damaged.

[0017]

According to the present invention, even if a compression force or a tensile force acts on the eaves gutter due to expansion and contraction of the eaves gutter, the compression force and the tension force are not elastic. Is absorbed and relaxed by the compressive and tensile deformation of the drain port having the drain port and the portion from the upper edge of the drain port to the inner upper end on the entrance corner, or the portion from the upper edge of the drain port to the outer upper edge on the exit corner side. Moreover, breakage of the eaves gutter joint caused by expansion and contraction of the eaves gutter can be prevented.

Further, since the drainage port is made of an elastic body, even if the eaves gutter bending joint is displaced in the horizontal direction due to expansion and contraction of the eaves gutter, this displacement is absorbed by the deformation of the drainage port. Damage to the connection with the downspout connected to the lower end can be prevented.
