Description
先ず、図1(a)を参照して、従来のミシン針における上糸の解撚発生のメカニズムについて説明する。この図1(a)は従来のミシン針の針穴周辺の模式拡大図であって、1は針幹部、2は表溝(長溝)、3は針穴、Tは上糸、Z−Zは針軸中心線、mは上糸Tを構成する複数本のフィラメントによる撚り目、θは撚り目mの傾斜角、Fは針穴3の上端縁3aの部分において上糸Tに作用するしごき力である。
本発明に係るミシン針の一実施の形態を図2〜図4に示す。図2は針穴とその周辺部分の拡大正面図、図3(a)〜(e)は図2中のA−A〜E−E線各位置における断面図、図4は針穴部分の拡大図である。

3 針穴
3a 針穴の上端縁
4 クランク部
5 針先
6 エグリ部
Z−Z 針軸中心線
T 上糸
m 上糸の撚り目
θ 撚り目の傾斜角
W 表溝の溝幅
Claims (4)
- 針軸中心線Z−Zに一致させて針幹部先端に形成された針先と、針先近傍に形成された唯一の針穴と、針幹部表側に位置して針軸中心線Z−Zと平行に針幹部上部側から針穴位置まで形成された表溝とを備えたミシン針において、
前記針穴につながる表溝の針穴直前部分を、針軸中心線Z−Zに対して上糸の撚り目の傾斜角と同程度の角度に傾斜させてクランク部とし、該クランク部を介して表溝と針穴をつなぎ、前記クランク部の溝の深さは針幹部上部側の表溝よりも浅く形成されていることを特徴とするミシン針。 - 前記クランク部の溝形状を、上糸の外径寸法と同程度の寸法からなる断面凹弧状としたことを特徴とする請求項1記載のミシン針。
- 前記クランク部につながる針穴の上端縁の穴幅をクランク部に向けて細く絞り、針穴とクランク部とを滑らかにつないだことを特徴とする請求項1または2記載のミシン針。
- 前記表溝の溝幅を、上糸がミシンの張力によって伸張されたときの糸直径と無張力時の糸直径との間の中間の寸法に設定したことを特徴とする請求項1〜3のいずれかに記載のミシン針。
