Description

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 ends of two eaves gutters.

[0002]

2. Description of the Related Art In buildings such as houses, eaves gutters are often arranged along the eaves. Most of these eaves gutters have a long length of about 3 to 5 m. In addition, these ends must be connected to each other at a high place under the eaves. For this reason, it is desirable to connect eaves gutters as easily as possible.

In response to such a request, for example, actual fairness 4-12
As shown in Japanese Patent No. 175, an eaves trough joint has been devised which enables the eaves trough to be easily connected to the eaves trough joint from its longitudinal direction.

In the case of this type of eaves trough joint, since the eaves trough is moved in the longitudinal direction and connected to the eaves trough joint, the connection itself is simple, but a long eaves trough at a high place is required. I couldn't get to the point where I could exchange them in the longitudinal direction and connect them, and some troublesome parts remained.

Therefore, recently, as shown in FIG. 6, a rectangular selvage 2 is projected outward on the upper portion of both side walls (only one side is shown) 1 having a substantially U-shaped cross section. Eaves gutter 3
Eaves gutter joint 4 that can be fitted to the end of the floor with one touch from below
Has been devised. This eaves trough joint 4 has a substantially U-shaped cross section similar to the eaves trough 3, and has a substantially U-shaped cross section in which the edge 2 of the eaves trough 3 is fitted on the upper portions of both side walls (only one side is shown) 5. A character-shaped edge fitting portion 6 is provided.

According to this, the eaves troughs 3 and 3 can be connected by aligning the ends of the two eaves troughs 3 and 3 and pushing the eaves trough joint 4 upward from below. At this time, as shown in FIG. 6 (B), the adhesive 8 is applied from the side wall 5 to the bottom portion 7 of the eaves gutter joint 4,
The fitting state as shown in (A) is maintained.

[0007]

However, in the case of the eaves trough joint 4 described above, as shown by an arrow M in FIG. 6 (B), the eaves trough 3 has an eaves trough joint 4 centered on an upper corner portion 9 thereof. The lower corner portion 10 of the eaves gutter 3 scrapes up the adhesive 8 due to the rotation. For this reason, eaves gutter 3
Crimping between the eaves gutter joint 4 and the eaves trough joint 4 tended to be insufficient, and the water stop performance was sometimes impaired. In addition, after the edge 2 of the eaves gutter 3 is fitted into the edge fitting part 6 of the eaves trough joint 4, the edge fitting part 6 is changed over time.
There was also a tendency for the strength of the to deteriorate.

The present invention has been made against the background of such circumstances, and the eaves gutter joint having sufficient strength at the selvage edge fitting portion while maintaining the waterproof performance with sufficient crimping with the eaves gutter. Is intended to provide.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is an eaves gutter having a substantially U-shaped cross section and having rectangular edge edges projecting outward at the upper portions of both side walls. In an eaves gutter joint that is fitted from below to the end of the eaves gutter, it has a cross-sectional shape that is substantially similar to the cross-sectional shape of the eaves gutter, and the edge is fitted in the upper portions of both side walls with an approximately U-shaped cross section. A fitting portion is provided, and a pressing portion that presses the ear edge against the upper wall portion of the ear edge fitting portion when the ear edge is fitted is straddled between the bottom surface portion inside the ear edge fitting portion and the vertical wall portion. It is characterized by being formed.

[0010]

In the eaves trough joint according to the present invention, the eaves trough joint has a sectional shape substantially similar to that of the eaves trough.
Then, on the upper portions of both side walls of the eaves trough joint, there are provided edge edge fitting portions having a substantially U-shaped cross section into which the ear edges of the eaves trough are fitted.
Further, a pressing portion that presses the ear edge against the upper wall portion of the ear edge fitting portion when the ear edge is fitted is formed across the inner bottom surface portion and the vertical wall portion of the ear edge fitting portion. This causes the eaves trough fitted in the eaves joint to rotate with respect to the eaves joint around the upper corner of the selvage, but at this time, the lower corner of the selvage becomes the selvage fitting part. It can be lifted upward by the provided pressing portion. That is, the upper corner portion of the edge is also lifted upward. Therefore, the degree to which the lower corner of the eaves gutter scrapes up the adhesive is alleviated.

Further, since the pressing portion of the eaves trough joint is formed so as to straddle the inner bottom surface of the edge fitting portion and the vertical wall portion, the elastic force of the edge fitting portion is reinforced. .

The ear edge fitting portion 16 is provided with a pressing portion 17 for pressing the ear edge 13 against the upper wall portion 16a of the ear edge fitting portion 16 when the ear edge 13 is fitted.

As shown in FIG. 2, the pressing portion 17 is formed in a wedge shape so as to straddle the inner bottom surface portion 16b of the edge fitting portion 16 and the vertical wall portion 16c, and is formed integrally with the eaves gutter joint 14. Has been done.

Next, the operation of the eaves gutter joint 14 having such a configuration will be described.

The eaves gutter 11 has an edge 13 as shown in FIG.
Is fitted to the eaves trough joint 14 while rotating with respect to the eaves trough joint 14 about the upper corner portion 13a of the ear edge 13a. At this time, the lower corner portion 13b of the ear edge 13 is pressed against the ear edge fitting portion. 1
It comes to be lifted up (forced guidance) by 7. That is, the upper corner portion 13a of the edge 13 is also lifted upward. Along with this, the lower corner portion 11a of the eaves gutter 11 is formed on the bottom surface portion 14a of the eaves gutter joint 14.
As a result, the degree to which the adhesive (not shown) applied to the surface of the bottom surface portion 14a is scraped off is relaxed.

Further, the pressing portion 17 of the eaves gutter joint 14 is
Since the inner edge fitting portion 16 is formed so as to straddle the inner bottom surface portion 16b and the vertical wall portion 16c, the elastic force of the edge fitting portion 16 (the force in the direction indicated by the arrow N in FIG. 2) is It is reinforced.

FIGS. 3 to 5 show modified examples of the eaves-and-groove joint described up to this point, and the shapes of the pressing portions provided in the edge fitting portions are different from each other.

In the case of the eaves gutter joint 31 shown in FIG. 3, the pressing portion is composed of two small wedges 32a and 32b, and the ends of the eaves gutter which are independently connected to each other are pushed up. This weakens the degree to which the wobble of one eaves gutter is transmitted to the other eaves gutter.

In the case of the eaves gutter joint 41 of FIG. 4, the pressing portion 4
The surface of 2 is a curved surface. As a result, when the edge of the eaves gutter is fitted, the edge of the ear gutter engages the upper wall portion 43a of the edge fitting portion 43.
The momentum that pushes up is moderate.
