DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves gutter joint for connecting two eaves gutters, and more particularly to an eaves gutter joint arranged along the inner surface of an eaves gutter.

[0002]

2. Description of the Related Art Generally, an eave of a house is provided with an eave gutter for receiving rainwater on the roof. A plurality of eaves gutters are arranged in a row along the eaves. Two adjacent eaves gutters are connected via a joint straddling between them. However, the appearance may be impaired by the joint. Therefore, a construction method in which the joint is formed in a substantially U-shaped plate shape, which is attached to the inner surface of the eaves gutter, and is bonded with an adhesive, or the upper edge is locked to the ear of the eaves gutter, is often used. (Japanese Unexamined Patent Publication No.
No. 161056). As a result, the joint can be made invisible from outside, and an aesthetic appearance can be secured.

[0003]

However, since the roof eaves face the upper opening of the eaves gutter, there has been a problem that it is difficult to put the joint into the eaves gutter.

[0004]

In order to solve the above problems, the present invention is attached to the inner surface of the eaves gutter so as to straddle between the two eaves gutters and connects the eaves gutters to each other. Pertaining to the eaves gutter joint. The joint has an outdoor side plate portion attached to the outdoor side wall of the eaves gutter, a bottom plate portion connected to the lower edge of the outdoor side plate portion and attached to the bottom of the eaves gutter, and an edge of the bottom plate portion on the house side. And a house side plate portion attached to the house side wall of the eaves gutter. The house side plate part forms an obtuse angle with respect to the bottom plate part in a natural state before being connected to the eaves gutter and is inclined toward the house side from the house side wall, and a groove is formed at a boundary with the bottom plate part. This makes it possible to bend it outdoors. As a result, even if the eaves face the upper opening of the eaves gutter, the house side plate of the joint can be easily inserted into the eaves gutter through the gap between the eaves and the upper end of the outdoor side wall of the eaves gutter. it can. Consequently, the entire joint can be easily inserted into the eaves gutter. Then, the house side plate portion can be bent and attached to the house side wall of the eaves gutter.
Here, “house side” means a side that faces the house when the joint is installed on the eaves gutter, and “outdoor side” means a side that faces the outdoor.

[0005]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 2, the house 1 is provided with a gutter device M that collects rainwater falling on the roof 2 and guides the rainwater to the ground. The gutter device M includes a plurality of eave gutters 10 and an eave gutter joint 20 connecting the eave gutters 10. Figure 1
2, each eaves gutter 10 has front and rear (outdoor side and house side) walls 11, 12 and a bottom plate 13 (bottom), has a substantially U-shaped cross section, and is horizontally elongated. Extending.
The plurality of eaves gutters 10 are arranged in a row along the eaves 3 of the roof 2, and ends of two adjacent eaves gutters 10 abut each other. The eave 3 faces the upper surface opening of the eave gutter 10.

In the eaves gutter 10, the eaves gutter joint 20 is accommodated in a contact portion between ends. Figure 1
As shown in FIG. 3, the joint 20 is formed of a synthetic resin such as hard vinyl chloride, and has front and rear plate portions 21 and 22.
And a bottom plate portion 23 connecting the lower edges of these plate portions 21 and 22.
And

The front plate portion 21 (outdoor side plate portion) is straddled between two eaves gutters 10 so that the front wall 11 of these eaves gutters 10 is provided.
It is attached to the house side (the inner surface of the eaves gutter 10) of the (outdoor side wall). An ear engaging portion 21 a is provided at an upper end of the front plate portion 21. The locking portion 21a is fitted into the front ear 11a at the upper end of the front wall 11. A step 21 b is provided on the lower side of the front plate portion 21, and the step 21 b is
Is attached so as to cover the step 11b.

[0008] The bottom plate portion 23 is straddled between the two eaves gutters 10, and the upper surface of the bottom plate 13 of these eaves gutters 10 (eave gutters 10).
Inside).

The rear plate portion 22 is attached to the outdoor side surface (the inner surface of the eaves gutter 10) of the rear wall 22 (house side wall) of the eaves gutter 10 so as to straddle between the two eaves gutters 10. Rear plate 2
The upper end edge of the rear wall 12 abuts on the lower end edge of the rear ear 12a of the upper end of the rear wall 12. (Note that, similarly to the front plate portion 21, the rear plate portion 22 may be provided with an ear locking portion that is fitted into the ear 12a and locked.)

The eaves gutter 10 and the joint 20 are adhered to the joint surface between the eaves gutter 10 and the joint 20 by applying an adhesive (not shown). Thus, two adjacent eaves gutters 10 are connected via the joint 20. The adhesive also serves to seal rainwater from leaking between the eaves gutter 10 and the joint 20.

The features of the present invention will be described. As shown in FIG. 3, the rear plate portion 22 of the joint 20 forms an obtuse angle with the bottom plate portion 23 in a natural state before being connected to the eaves gutter 10 and is inclined toward the house. That is, the eaves gutter 10
Is inclined toward the house side from the vertical rear wall 12. On the inner side of the boundary between the rear plate portion 22 and the bottom plate portion 23, a groove 20a is formed over the entire width. The groove 20a allows the rear plate portion 22 to be easily bent to the outside of the bottom plate portion 23 with little force.

A method of connecting the eaves gutter 10 by the eaves gutter joint 20 configured as described above will be described. In advance, eaves gutter 1
0 or one of the joints 20 is coated with the adhesive. Then, as shown in FIG.
Is inserted into the eaves gutter 10 through a gap between the upper end of the front wall 11 of the eaves gutter 10 and the eaves 3. At this time, since the rear plate portion 22 forms an obtuse angle with respect to the bottom plate portion 23, the insertion operation can be easily performed. As a result, the bottom plate 23 can be easily inserted.

As shown in FIG. 5, for example, the rear plate 22 is raised while the upper end of the rear plate 22 is hooked on the corner between the rear wall 12 and the rear ear 12a of the eaves gutter 10 (see FIG. 5). Further, the insertion operation is performed while bending the bottom plate portion 23 to the outdoor side. Thus, the entire joint 20 can be easily inserted into the eaves gutter 10 while preventing the joint 20 from hitting the eaves 3. In addition, the joint 20 can be inserted while preventing the inner surface of the eaves gutter 10 from rubbing against the inner surface of the eaves gutter 10, especially while preventing the corner between the bottom plate 23 and the rear plate 22 from sliding against the bottom plate 13. This can prevent the adhesive from peeling off.

Then, as shown in FIG. 2, two eaves gutters 1
The rear plate portion 22 is attached to the rear wall 12 and the bottom plate portion 23 is attached to the bottom plate 13 so as to straddle between the 0 end portions. Further, the ear engaging portion 21a is fitted into the front ear 11a, and the front plate 2
1 is attached to the front wall 11. As described above, since the adhesive does not peel off, the joint 20 and the eaves gutter 10 can be securely bonded, and thus the two eaves gutters 10 can be reliably connected. Furthermore, the water stoppage between the joint 10 and the eaves gutter 20 can be reliably ensured.

The present invention is not limited to the above embodiment, and various modifications are possible. For example, the groove 20a is
It may be formed on the outer surface side of the boundary between 2 and the bottom plate portion 23.

[0016]

As described above, according to the present invention,
Even if the eaves face the upper opening of the eaves gutter, the house side plate portion of the joint can be easily inserted into the eaves gutter through the gap between the eaves and the upper end of the outdoor side wall of the eaves gutter. Consequently, the entire joint can be easily inserted into the eaves gutter. And
The house side plate can be bent and attached to the house side wall of the eaves gutter.
