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 eaves gutters attached to the eaves of a building.

[0002]

2. Description of the Related Art As a conventional eaves-and-spout joint, for example, one described in Japanese Patent Laid-Open No. 20646/1992 is known.

This conventional eaves gutter joint is used at the corner of the eaves and is called a curved joint. The plane elongate joint is formed into an L shape, and the ends of the eaves gutter are fitted to both ends. An eaves gutter connection is provided. In addition, on the inner surface of this eaves trough connection part, a rising part raised from the inner surface of the eaves gutter connection part at a right angle to the eaves gutter connection part, and from the upper end of the rising part to the tip side of the eaves gutter connection part An eaves gutter presser piece consisting of a eaves trough connection part and a parallel part extending parallel to the eaves gutter connection part is provided, and when the end part of the eaves gutter is fitted into the eaves gutter connection part, this eaves gutter presser piece is provided. When the end of the eaves gutter is inserted between the eaves gutter connection part and the eaves gutter connection part, the outer surface of the eaves gutter does not rise above the inner surface of the eaves gutter connection part.

[0004]

However, in the above conventional eaves gutter joint, the rising part of the eaves gutter presser piece provided on the inner surface of the eaves gutter connection part is perpendicular to the eaves gutter connection part. Since the rainwater travels from the eaves joint to the eaves fitted to the eaves joint of the eaves joint, the rainwater hits the rising part of the eaves retainer and jumps up, causing turbulence. There was a problem that the flow occurred.

As a means for solving this problem, as shown in FIG. 4, the eaves gutter pressing piece 20 is formed on the outer surface side of the eaves gutter connecting portion 10 so as not to cause a step on the inner surface of the eaves gutter joint. As is well known, in this case, since a step is formed on the outer surface of the eaves-and-groove joint, another problem that the appearance is greatly deteriorated occurs.

Further, in Japanese Utility Model Laid-Open No. 4-68131,
In a stretchable eaves gutter joint, a structure is described in which the outer surface of the rising part of the eaves gutter presser piece is inclined toward the tip side of the eaves gutter connection part. In this structure, rainwater flows from the eaves joint
On the way to the eaves trough fitted to the eaves trough connection part of the eaves trough joint, the erecting of the eaves trough retaining piece does not bounce up by changing the direction of the flow diagonally along the rising edge of the eaves trough retaining piece. The outer surface of the part is inclined with respect to the eaves gutter connection part, while the inner surface is at a right angle to the eaves gutter connection part, and since the wall thickness is uneven, sink marks are likely to occur during molding. There was another problem.

In view of the above problems, the present invention can prevent rainwater from generating turbulent flow, and can prevent the appearance from being damaged and sink marks to be generated during molding. The purpose is to provide an eaves trough joint that can be made.

[0008]

In order to achieve the above object, the eaves gutter joint of the present invention has eaves gutter connection portions at both ends thereof to which the ends of the eaves gutter can be fitted. On the inner surface of the connection part,
Eaves gutter presser consisting of a rising part raised from the inner surface of the eaves gutter connection part, and a parallel part extending parallel to the eaves gutter connection part from the upper end of the rising part toward the tip side of the eaves gutter connection part. In the eaves gutter joint provided with a piece, the rising part of the eaves gutter presser piece is inclined toward the tip side of the eaves gutter connection portion and is formed with a substantially uniform wall thickness. In addition, it is preferable to chamfer the outer corner of the tip of the horizontal part of the eaves gutter pressing piece.

[0009]

In the eaves trough joint of the present invention, since the rising part of the eaves trough retainer is inclined toward the tip side of the eaves trough connection part, rainwater in the trough is connected to the eaves trough joint from the eaves trough joint. On the way to the eaves gutter fitted to the eaves gutter connection part, only the direction of the flow is changed diagonally along the rising part of the eaves gutter presser piece, and it does not bounce.

Further, in the eaves gutter joint of the present invention, since the rising part of the eaves gutter pressing piece is formed with a substantially uniform wall thickness, sink marks do not occur during molding.

Further, in the eaves trough joint of the present invention, since the eaves trough pressing piece is formed on the inner surface of the eaves trough connection portion, it is possible to prevent a step from being formed on the outer surface of the eaves trough joint.

Further, in the eaves trough joint according to the second aspect of the present invention, the outer corner of the tip of the horizontal portion of the eaves gutter pressing piece is chamfered, so that the resistance of the tip of the horizontal portion to the flow of rainwater becomes small.

[0013]

Embodiments First, the construction of an eaves gutter joint of the embodiment will be described with reference to FIGS. 1 and 2. The eaves gutter joint of this embodiment is
It is used in the outer corner of the eaves and is called a bend.

FIG. 3 is a diagram showing the flow of rainwater in the eaves-and-groove joint of this embodiment. In the eaves gutter joint A of this embodiment, the outer corners 221 of the tips of the parallel portions 22 of the eaves gutter pressing piece 2 are chamfered, so that the resistance of the tips of the parallel portions 22 to the flow of rainwater is small. Therefore, rainwater is
As indicated by the arrow a, the eaves trough B is fitted into the eaves trough joint 1 of the eaves trough joint A, and smoothly flows into the eaves trough joint A. Moreover, since the rising part 21 of the eaves gutter presser piece 2 is inclined toward the tip side of the eaves gutter connection part 1, rainwater in the gutter will not be absorbed by the eaves gutter joint A.
On the way to the eaves trough A fitted to the eaves trough connection portion 1 of the eaves trough joint A, as shown by an arrow b, the flow of the slanting flow along the rising portion 21 of the eaves trough retainer piece 2 is increased. Just turn around and don't bounce. Therefore, the rainwater does not generate a turbulent flow in the eaves-spout joint A.

Further, in the eaves gutter joint A of this embodiment, since the rising part 21 of the eaves gutter presser piece 2 is formed with a substantially uniform thickness, sink marks do not occur during molding, and the eaves gutter Since the outer shape is such that no step is formed in the direction of disturbing the axial line of the joint A, the appearance is also good.
