【考案の詳細な説明】 産業上の利用分野 本考案は、排水、灌漑用等の用途に使用されるホースを
順次接続するための金具に関するものである。TECHNICAL FIELD The present invention relates to a metal fitting for sequentially connecting hoses used for applications such as drainage and irrigation.
近年、低海抜地域においては、台風等により集中豪雨を
受けた場合、その雨水の排水が追いつかず、浸水等の被
害がでている。そこで近年この水を大口径のホースで強
制的に揚水して排水することが検討されている。In recent years, in a low sea level area, when a heavy rainfall is caused by a typhoon or the like, the drainage of the rainwater cannot catch up and damage such as inundation occurs. Therefore, in recent years, it has been considered to forcibly pump and drain this water with a large-diameter hose.
この場合に要求されるホースは、一般に少くとも400mm
以上の大口径のものであり、このような大口径のホース
を長尺のもので用意するのは、敷設や運搬に不便であ
る。従って通常は、数十ｍ程度の短いホースを多数用意
し、これを順次接続して所望の長さを得ることが必要で
ある。そしてそのための接続金具が要求されている。The hose required in this case is generally at least 400 mm
It is a large diameter hose as described above, and it is inconvenient to lay and transport the hose having such a large diameter. Therefore, it is usually necessary to prepare a large number of short hoses each having a length of several tens of meters and connect them sequentially to obtain a desired length. And the connection metal fittings for that are required.

Description of the Related Art As a conventional metal fitting for a hose of this type, a hose having an inner diameter approximately equal to the outer diameter of the metal fitting is fitted to both ends of a tubular metal fitting body, and a metal band or the like is attached from the outer circumference of the hose. The hose and the metal fitting body are joined by tightening with.
この結合構造を第４図及び第５図に従って説明すると、
金具本体１の筒体２の外周面に環状の凹溝３が刻設され

屈曲挟持せしめている。This bonding structure will be described with reference to FIGS. 4 and 5.
An annular groove 3 is engraved on the outer peripheral surface of the tubular body 2 of the metal fitting body 1, and a hose 4 is fitted from the end of the tubular body 2 to the outer periphery thereof. At the position of, the metal band 5 is tightened, and the hose 4 is bitten into the concave groove 3 so as to be bent and clamped.

である。However, in this joint structure, when the metal band 5 is tightened, the metal band 5 is strongly tightened and then the
As shown in the figure, both ends of the metal band 5 are fixed by the buckle metal fittings 6 to maintain the tightened state. Therefore, when the metal band 5 is tightened, the hose 4 bite into the concave groove 3 of the tubular body 2 is pulled in the circumferential direction due to friction with the metal band 5, and wrinkles 7 are formed. In particular, since the inner diameter of the hose 4 is approximately equal to the outer diameter of the tubular body 2, there is a margin in the hose portion that digs into the groove 3, and the margin is brought close to the buckle metal fitting 6 by friction with the metal band 5. Then, it appears as wrinkles 7.
そしてこのような皺７がよると、この皺７の部分を通じ
て漏水し、また皺７の部分はホースが一部重なって締付
けられることとなるため、傷付き易い。When the wrinkles 7 are formed, water leaks through the wrinkles 7, and the hose is partially overlapped with the hose so that the hose is easily damaged.

The purpose of the present invention is to provide a joint structure that is not damaged.
