Description

【０００１】
【発明の属する技術分野】
本発明は、家屋の軒先に設けられる曲り継手に関する。
【０００２】
【従来の技術】
従来、軒先の軒樋同士を接続する曲り継手としては、例えば、実開平３−８２７３８号公報と、又、曲り継手の支持具としては、例えば、実開平６−７９９３６号公報に記載されているようなものがある。
前者の実開平３−８２７３８号公報に記載の曲り継手は、略Ｌ字型に形成され、軒樋を嵌合可能な軒樋嵌合部が両端に設けられ、軒樋嵌合部の内周面にパッキングと、略Ｌ字に形成された曲り継手の入隅側の一片と他片の外壁面に係止具とが設けられているものである。
【０００３】
この曲り継手は、曲り継手の入隅側（屋内側）の一片と他片の外壁面に設けられた係止具を、軒先の出隅部に一片と他片に取り付けられた取付金具に取り付け、曲り継手の軒樋嵌合部に軒樋の両耳部を嵌めて、軒樋嵌合部の内周面に設けられられたパッキングで側壁や底部からの漏水を防ぎ、軒樋と曲り継手とを接続しているもので、簡単な構造で、使い易いものである。
【０００４】
後者の実開平６−７９９３６号公報に記載の曲り継手の支持具は、固定部と、この固定部から屋外方向に長く突出した腕部と、腕部の屋外側先端に２個の屋外側保持部と、この屋外側角部保持部より屋内側に屋内側角部の２個の屋内側係止部とが設けられているものである。
この曲り継手の支持具は、曲り継手の屋外側耳部を外側から２個の屋外側保持部に嵌め込み、屋内側耳部を２個の屋内側係止部に嵌め込み、固定部を軒先の出隅部に取り付けて曲り継手を支持具で支持しているもので、簡単な構造で、使い易いものである。
【０００５】
【発明が解決しようとする課題】
ところが、軒樋は、気温の変化に伴って、軒樋の長さ方向や幅方向に伸縮し、軒樋の伸縮に伴って曲り継手も伸縮し、軒樋や曲り継手が変形することがある。
上記の実開平３−８２７３８号公報に記載の曲り継手は、曲り継手の入隅側（屋内側）の外壁面が軒先の出隅部に繋がれ、固定しているもので、曲り継手の出隅側（屋外側）は固定されておらず、曲り継手の出隅側（屋外側）で気温の変化に伴って伸縮し、変形することがあり、軒樋嵌合部に隙間ができ、漏水するという問題がある。
【０００６】
又、実開平６−７９９３６号公報に記載の曲り継手の支持具は、曲り継手の入隅側（屋内側）と出隅側（屋外側）でしっかりと曲り継手を支持しているが、曲り継手の入隅側（屋内側）と出隅側（屋外側）のそれぞれ２箇所で曲り継手の耳部を掴んで支持しているため、支持具自体が大きくなり、嵩張って持ち運びに手間が掛かるという問題があり、又、伸縮による変形で掴んでいる耳部が外れることがあるという問題がある。
【０００７】
そこで、本発明の目的は、上記のような問題に着目し、温度変化があっても、曲り継手の入隅側（屋内側）と出隅側（屋外側）で変形し軒樋嵌合部に隙間ができず漏水せず、掴んでいる耳部が外れず、嵩張らず持ち運びに手間が掛からない曲り継手を提供するものである。
【０００８】

BACKGROUND OF THE INVENTION
The present invention relates to a bent joint provided at the eaves of a house.
[0002]
[Prior art]
Conventionally, as a bent joint for connecting eaves at the eaves, for example, Japanese Utility Model Laid-Open No. 3-823838 is disclosed, and as a support for the bent joint, for example, Japanese Utility Model Laid-Open No. 6-79936 is described. There is something like this.
The former bent joint described in Japanese Utility Model Publication No. 3-823838 is formed in a substantially L shape, and is provided with eave ridge fitting portions capable of fitting eave ridges at both ends. A packing is provided on the surface, and a locking member is provided on the outer wall surface of one corner and the other piece of the bent joint formed in a substantially L shape.
[0003]
This bend joint attaches the fasteners provided on the outer wall surface of one corner and the other side of the corner joint (indoor side) of the bend joint to the mounting bracket attached to the one corner and the other piece on the outer corner of the eaves. By fitting both ears of the eaves to the eaves fitting fitting part of the bent joint, the packing provided on the inner peripheral surface of the eaves fitting fitting prevents water leakage from the side wall and bottom, Is easy to use with a simple structure.
[0004]
The latter bent joint support described in Japanese Utility Model Laid-Open No. 6-79936 has a fixed portion, an arm portion that protrudes long in the outdoor direction from the fixed portion, and two outdoor side holdings at the outdoor end of the arm portion. And two indoor side locking portions of the indoor side corner portion are provided on the indoor side from the outdoor side corner holding portion.
The support for this bent joint is to fit the outer ears of the bent joints into the two outdoor holding parts from the outside, the indoor ears into the two indoor locking parts, and the fixed part at the corner of the eaves The bent joint is supported by a support and is simple in structure and easy to use.
[0005]
[Problems to be solved by the invention]
However, the eaves can expand and contract in the length and width directions of the eaves as the temperature changes, and the elongate and elongate joints can expand and contract as the eaves expands and contracts. .
The bending joint described in the above-mentioned Japanese Utility Model Publication No. 3-823838 is such that the outer wall surface on the corner side (indoor side) of the bending joint is connected and fixed to the protruding corner of the eaves. The corner side (outdoor side) is not fixed, and the bent joint side (outdoor side) may expand and contract as the temperature changes, deforming, creating a gap in the eaves fitting part, and leaking water There is a problem of doing.
[0006]
Further, the bent joint support described in Japanese Utility Model Publication No. 6-79936 supports the bent joint firmly at the entrance corner side (indoor side) and the exit corner side (outdoor side) of the bend joint. Since the corner of the joint is gripped and supported at two places, the entrance corner side (indoor side) and the exit corner side (outdoor side) of the joint, the support itself becomes large and bulky and laborious to carry. There is a problem of hanging, and there is a problem that an ear portion gripped by deformation due to expansion and contraction may come off.
[0007]
Therefore, the object of the present invention is to pay attention to the above-mentioned problems, and even if there is a temperature change, the bent joint is deformed at the entrance corner side (indoor side) and the exit corner side (outside side), and the eaves hook fitting portion Therefore, it is possible to provide a bent joint that does not have a gap, does not leak, does not come off the gripping ear part, is bulky, and does not take time to carry.
