Abstract
Description
(1)本発明のホースクランプは、幅広領域及び幅狭領域の長手方向の両端部に略径方向外方へ屈曲してそれぞれ第1、第2の摘み操作片が形成される一方、幅広領域の幅方向の側縁には幅狭領域との境界部から第1摘み操作片にほぼ至る長さ範囲に亘って曲げ部であるフランジが折り曲げ形成され、幅狭領域の幅方向の両側縁間には幅広領域との境界部から第2摘み操作片にほぼ至る長さ範囲に亘って曲げ部であるビードがプレス加工によって曲げ形成されている構成とすることが好ましい。
このような構成によれば、幅広領域では側縁を折り曲げことでフランジを容易に形成することができる。また、幅狭領域では幅方向の中央部をプレス加工によってビードを形成するようにしたため、側縁の折り曲げが困難な幅狭領域においても容易に曲げ部を形成することができる。
(2)前記ビードと前記フランジとは長手方向に関して一部がラップするようにしてもよい。
仮にも、ラップさせない場合には、ビードとフランジとの境界部位に応力が集中してしまい、当該部位で変形を生じてしまうが、上記のような構成によれば、こうした応力集中を回避することができる。
このような構成によれば、フランジがホース等への差し込みに際し、締め付け部の幅方向の側縁がホース等の端面に引っ掛かりにくく、差し込み作業を容易に行うことができる。
(7)前記フランジは、前記幅広領域の両側縁を外面側へ弧状に巻き込んでカールさせることによって形成されるようにしてもよいし、また幅広領域の両側縁を外面側へ密着して折り曲げることによって形成されるようにしてもよい。
図1乃至図8は本発明の実施例1に係るホースクランプ1を示している。このうち、図5はホースクランプ1の展開図を示している。同図に示すように、ホースクランプ1は帯状の板ばね材により形成されている。また、その長さ範囲の略2/3程度は相対的に幅の広い幅広領域(図5に示すX1領域)であり、残りの略1/3程度は相対的に幅の狭い幅狭領域(同図に示すX2領域)となっている。
また、ビード7は、外向きに突出するようプレスにより曲げ加工にて形成されている。その断面形状は、図7に示すように、頂縁が弧状をなし裾野側へ向けて拡がる湾曲形状に形成されている。本実施例では、ビード7の突出高さ及び幅(ビード7の延び方向と直交する方向の幅)は全長に亘って均一に形成されている。

図12は、実施例3に係るホースクランプ20の幅狭領域X2側を拡大して示している。同図に示すように、幅狭領域X2の幅は幅広領域X1との境界部分から先端側に至る所定長さ範囲(Lで示された範囲)に亘って寸法が漸減するように形成されている。このことに対応して、ビード21自体の幅寸法も同様に先端側に向けて漸減するようにしてある。より詳細には、ビード21はX軸を中心として対称形状に形成されている。また、その一端部は幅広領域側に少し食い込んだ部位に位置し、Lで示された範囲の端部に近接した部位に至る範囲に形成され、先端側へ行くにつれて徐々に幅寸法が小さくなるように形成されている。
図13は実施例4に係るホースクランプ30のフランジ31を拡大して示している。このような断面形状のものも本発明のフランジの概念に包含される。すなわち、実施例4のフランジ31は幅方向の両側縁を外周面側へ巻き込んでカールさせたものである。このようなフランジ31が形成される長さ方向(周方向)の範囲は、実施例1及び実施例2と同じである。巻き込み高さは全長さ範囲に亘って均一でもよいし、Y軸から先端側に行くにしたがって対称にかつ徐々に小さくするようにしてもよい。
図14は実施例5に係るホースクランプ40のフランジ41を拡大して示している。このような断面形状のものも本発明のフランジの概念に包含される。すなわち、実施例5のフランジ41は幅方向の両側縁を外周面側へ密着状態で折り返したものである。このようなフランジ41が形成される長さ方向(周方向)の範囲は、実施例1及び実施例2と同じである。折り返し幅は全長さ範囲に亘って均一でもよいし、Y軸から先端側に行くにしたがって対称にかつ徐々に小さくするようにしてもよい。
本発明は上記記述及び図面によって説明した実施例に限定されるものではなく、例えば次のような実施例も本発明の技術的範囲に含まれる。
(1)上記実施例では、幅広領域側と幅狭領域側とで二種類の異なる曲げ部(フランジとビード)を設けたが、同種の曲げ部、例えば幅広領域と幅狭領域の双方にフランジ、あるいは双方にビードを形成するようにしてもよい。
(2)上記実施例では、ホースクランプを拡径状態に保持する手段を持たない形式であったが、別体のホルダーを設けて接近状態にある両摘み操作片を保持するようにしてもよい。
(3)上記実施例では、幅広領域側の先端同士が連結されて開口部が閉じている形態を示したが、非連結として開口部が先端側へ開放するような形態としてもよい。
(4)上記実施例では、フランジの曲げ方向及びビードの突出方向は共に外方であったが、いずれも内方へ向けてのものであってもよい。
(5)上記実施例では、フランジ及びビードは長さ方向(周方向)に連続して形成される形態を示したが、複数個に分割して断続的に形成される形態であってもよい。
(6)上記実施例では、ビードを一条だけ形成したが、複数条を並列して形成するようにしてもよく、また途中で複数条に分岐するようにしてもよい。
