Description

[Detailed description of the invention] The present invention wraps around the outside of the hollow part 7 of the ear part 1 of the synthetic resin eaves gutter 3 in which a thin metal material 2 is insert-molded, and inserts the end of the metal material 2. ,
At the upper end of the ear part 1, there is an outer bending piece 5 extending upward and projecting along the outer surface of the ear part 1, and an outer bending piece 5 extending upward and projecting along the inner surface of the ear part. This relates to an eaves gutter ear structure characterized by comprising an inner bending piece 4 with a space provided between the outer bending piece 5 and the outer bending piece 5. To provide a structure for an eaves gutter which has an ear part that easily adapts to the cutting angle of scissors and is difficult to break.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

The eaves gutter 3 is made of synthetic resin into which a metal material 1 such as a thin steel plate is insert-molded, and the ears 1 are hollow. The end of the metal material 2, such as a steel plate, is wrapped around the outside of the hollow part 7 and inserted into the ear part 1. An elastic inner bending piece 4 and an outer bending piece 5 are respectively projected upward from the inside and outside of the upper end of the ear part 1. However, when cutting the eaves gutter 3 from the ear part 1 with scissors 6 as shown in FIG. When the bending is eliminated, the bending pieces 4 and 5 are cut at the cutting angle θ of the scissors 6.
The elasticity of the flexible pieces 4 and 5 can absorb the impact caused by cutting, and the ear part 1 can be prevented from cracking.

As mentioned above, the present invention has an outer flexible piece that extends upwardly and protrudes along the outer surface of the ear at the upper end of the ear, and an outer flexible piece that extends upward along the inner surface of the ear. Since the inner bending piece is formed to protrude and has a space between it and the outer bending piece, when cutting the eaves gutter from the ear part with scissors, the inner bending piece and the outer bending piece are held together with scissors. However, when cutting by bending them in opposite directions due to their elasticity, both bending pieces easily adapt to the cutting angle of the scissors, making cutting easier.
Moreover, the impact at the time of cutting can be absorbed by the elasticity of both flexible pieces, and as a result, cracking of the ears can be prevented.
