Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves trough bending joint for connecting eaves troughs at eaves corners of buildings such as houses.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional example of an eaves gutter bending joint for connecting eaves gutters at the corners of the eaves of a building such as a house. This eaves trough bending joint is the eaves trough 3, which we meet at the corner of the eaves corner.
An L-shaped bottom plate 11 for fitting the eaves gutters 3 and 3 by fitting the ends of the inner side of the inner part 3 to the inner side of the both ends and having an L-shape in plan view 11
And an L-shaped front plate 13 whose left and right surfaces cross L-shapes from the front edge of the L-shaped bottom plate 11 and an L-shaped rear plate which right and left surfaces cross L-shapes from the rear edge of the L-shaped bottom plate 11 The plate 12 and the plate 12, and the inner peripheral surfaces of both end portions are arranged along the outer peripheral surface of the eaves gutter 3. At the upper end of the L-shaped rear plate 12, a rising portion 14b which rises along the rear side of the rear ear 34 of the eaves gutter 3 and a forward bending from the upper end of this rising portion 14b along the upper side of the rear ear 34 A rear ear holding piece 14 including a holding portion 14a is provided. In this rear ear holding piece 14, the rising part 14b is an L-shaped rear plate.
As an extension of 12 upwardly, it is integrally formed on the left and right in an L shape, and the rear ear upper pressing portion 14a rises up at a corner.
The left and right sides of 14b are bent separately.

In order to connect the eaves gutters 3 and 3 at the eaves corners by the eaves gutter bending joint, the eaves gutter bending joint is pushed up against the end of the eaves gutter 3 from below. The method of inserting the gutter 3 into the eaves gutter bending joint and pushing it further to the inside and sliding it, or inserting the end of the eaves gutter 3 from the lateral outside to the end of the eaves gutter bending joint and sliding it further to the back Is being done. The former connection method is adopted when the shape of the front plate 33 of the eaves gutter 3 is relatively simple. In this case, the fitting is compared by using the elasticity of the eaves gutter bent joint and the eaves gutter 3. It can be done easily. On the other hand, when the shape of the front plate 33 of the eaves gutter 3 is complicated, generally, if the former connection method is adopted, the eaves gutter bent joint and the eaves gutter 3 must be largely elastically deformed. Has been adopted.

[0004]

By the way, when the eaves trough bending joint and the eaves trough 3 are connected by the latter connection method described above, the end portion of the eaves trough 3 is connected to the end portion of the eaves trough bending joint. It is easy to hit, which is especially true of the rear ear 34 and the rear ear retention piece 14.
It becomes remarkable at the fitting position with. That is, the front part of the eaves gutter 3 end can be visually checked to confirm the position with respect to the end of the eaves gutter joint, so that it is relatively easy to match the position, while the rear part of the eaves gutter 3 end is hidden. Since it is hard to see, it is necessary to confirm the position by touching or feeling, and the rear ear located at the tip of the rear part of the eaves gutter 3.
The end portion 34 easily hits the end portion 14 of the rear ear holding piece 14. In this case, when the rear ear holding piece 14 is elastically deformed rearward by pressing the end of the eaves trough 3 against the end of the eaves trough bending joint, the end of the eaves trough 3 is placed inside the end of the eaves trough bending joint. However, in the eaves gutter bending joint according to the above-mentioned conventional example, the rising part 14b of the rear ear holding piece 14 is integrally formed on the upper end of the L-shaped rear plate 12 in the left-right shape. The rear ear holding piece 14 is unlikely to be deformed rearward because it is formed in the shape. Therefore, when the end part of the eaves trough 3 is press-fitted and inserted into the end part of the eaves trough joint, a large pressing force may be required or the press-fitting may not be performed, which makes it difficult to fit the eaves gutter.

The present invention has been made in view of the above circumstances, and provides an eaves trough bending joint in which the eaves trough can be easily fitted.

[0006]

The eaves gutter bending joint according to claim 1 is an L-shaped bottom plate formed in an L-shape in plan view, and this L-shaped bottom plate.

In the eaves gutter bending joint provided with a rear ear holding piece consisting of a rising portion rising along the rear rising edge and a rear ear upper pressing portion that bends forward from the upper end of the rising portion and extends along the upper side of the eaves rearing ear, The holding pieces are formed separately at the upper ends of the left and right rear plate portions that intersect the L shape and form the L-shaped rear plate.

In this eaves gutter bent joint, the rear ear holding piece is L
Since the left and right rear plate portions forming the mold rear plate are formed separately at the upper ends thereof, the left and right rear ear holding pieces are easily elastically deformed rearward. Therefore, when the end of the eaves gutter is inserted into the end of the eaves gutter bending joint from the lateral outside and fitted, even if the end of the eaves gutter hits the end of the rear ear holding piece, By pressing the eaves trough, the rear ear holding piece can be elastically deformed rearward with a smaller pressing force than in the past, and the eaves trough can be press-fitted into the eaves trough bending joint. Therefore, the eaves trough bending joint is easily fitted into the eaves trough.

The eaves gutter bending joint according to a second aspect is the eaves trough bending joint according to the first aspect, wherein the rear upper ear holding portion of the rear ear holding piece extends from the front to the rear at an end portion in the eaves gutter insertion direction. It is characterized in that it has a taper portion that narrows toward the width.

In this eaves trough bending joint, when the end of the eaves trough is laterally inserted and fitted into the end of the eaves trough bending joint, the end of the eaves trough rear end is the end of the rear ear holding piece. Even if you hit
When the eaves trough is further pressed, the end of the rear ear slides along the taper portion of the rear ear upper pressing portion of the rear ear holding piece, and the rear ear holding piece is elastically deformed rearward to move the eaves trough. It can be press-fitted into the eaves trough bending joint. Therefore, the eaves gutter pressing force requires a smaller force, and thus the eaves gutter bent joint is more easily fitted into the eaves gutter.

The eaves gutter bending joint according to a third aspect is the eaves trough bending joint according to the second aspect, wherein the rear ear upper pressing portion is laterally outside at the upper end of the rising portion of the rear ear holding piece. It is characterized in that it is formed at a position that is inserted in the central direction.

In this eaves trough bending joint, since the rear upper ear pressing portion is formed at the upper end of the rising portion at a position which is inserted laterally from the outside toward the center of the joint, the rear upper ear pressing portion of the rising portion is more than the rear upper ear pressing portion. The portion protruding outward in the lateral direction serves as a guide, and when inserting the eaves gutter into the end of the eaves trough bending joint from the lateral direction outside, the rear ear does not shift back and forth and the rear ear of the rear ear holding piece It is guided to the taper portion of the upper pressing portion. Therefore, the eaves gutter bent joint is more easily fitted into the eaves gutter.
