のであつた。 Conventionally, eaves gutters made only of synthetic resin do not dent due to their elasticity against impact forces.
Also, while it has the advantage of not rotting over time and can last a long time, it has the disadvantage of being susceptible to deformation such as meandering due to heat. On the other hand, eaves gutters made only of metal materials do not deform due to heat, but are susceptible to deformation such as dents due to impact forces, and eaves gutters that are made of only metal materials do not deform due to heat, but are susceptible to deformation such as dents due to impact forces. However, if the covering material were to peel off, it would be susceptible to corrosion such as rust, making it difficult to withstand changes over time. A solution to these shortcomings is the metal thin plate insert eaves gutter, which has a thin metal plate embedded in a hard synthetic resin eave gutter body to compensate for the shortcomings of the hard synthetic resin and metal materials and take advantage of the strengths of both. However, this eaves gutter also has a problem. In other words, if the ears formed at both upper edges of the eaves gutter have a generally circular cross section, and a thin metal plate is buried in the ears with a generally circular cross section along the outer surface, the ears will be cut when cut with scissors. When the ear is deformed, it is difficult to return to the original approximately circular shape, and the thin metal plate is not approximately circular and the first
It tends to become as shown in Figure A to Figure 1 B, and for this reason, it is very difficult to fit the joint of the eaves gutter.

本考案は以上の点に鑑みて為されたものであ

4 is a thin metal plate. Metal thin plate insert eaves gutter 1
There are ears 3 having a substantially circular cross section on both upper edges of the trough-like body 2,
3 is formed to form the eaves gutter body 21, and a hollow part 31 is formed in the central part of the ear part. The metal thin plate 4 is buried along the gutter-like body of the eaves gutter body 21 made of hard synthetic resin, and is buried up to the position of the outer peripheral wall 32 of both the ears 3,3. The thin metal plate 4 embedded in the outer peripheral wall 32 has a substantially U-shaped cross section. That is, it is formed into a square shape with corner portions 5, 5 formed therein. In this case, when cutting with scissors, the ears 3, 3 are not deformed, but the thin metal plate 4 is deformed at the corner 5, as shown in FIG.
The circumferential length of the eaves and gutters is not large, making it easy to fit joints, etc. As shown in the enlarged view of the ear part in FIG. 3, when the upper wall piece 51 of the generally U-shaped thin metal plate 4 is buried so as to be inclined inward, it becomes more easily deformed than in FIG. 2. There is.

部のクラツクの伝播を防ぐことができる。 As described above, the thin metal plate insert eaves gutter of the present invention is formed by forming the thin metal plate embedded in the ear portion into a substantially U-shaped cross section with corner portions, so the ear portion is easily deformed. It does not deform to a large circumference like an elliptical shape, and fits well with joints, etc., and because it deforms easily, it prevents the propagation of cracks in the ears. can.
