Abstract
Description
そして、このような構成によれば、カシメ用突起が基布に打ち込まれたときに、貫通孔の周りに突設した環状壁が基布との摩擦力によって貫通孔の中心側へ変形し、カシメ用突起と貫通孔との間の隙間を小さくすることで、基布の一部がカシメ用突起によって貫通孔内に持ち込まれないようにすることができると記載されている。
そして、このような構成によれば、リベット部材の材料として硬い樹脂を使用した場合でも、突起の突出先端部の打撃による拡開変形を容易に行えて、突起の付け根や拡開変形部の付け根にクラックが発生することを防止でき、しかも突起による可撓性シートの貫通孔への引きずり込みを防止できると記載されている。
また、特許文献2に記載されたスナップ部材は、ポスト部(突起)を差し込む差込部(貫通孔)が、ポスト部の直径より小さな直径を有する小径孔部と大径孔部とを備えているが、このような2段構成に形成されていても、なおポスト部を差し込む際に大きな力を必要とし、さらに差し込む際のポスト部にかかる負荷が大きく、ポスト部が座屈してしまうという問題がある。
すなわち、本発明に係るスナップ部材は、円柱状のポスト部を備えたスナップ取付部材により可撓性基材に取り付けられるスナップ部材であって、前記スナップ部材は、前記可撓性基材を貫通したスナップ取付部材のポスト部が差し込まれる円形の差込口を有する差込部が形成された部材本体を備え、前記部材本体は、前記差込部の差込口の周囲に環状の壁部を介して形成された溝部を備え、前記差込部は、前記差込口の直径が前記スナップ取付部材のポスト部の直径より小さく、且つ、深さ方向に進むにつれて徐々に直径が大きくなるテーパ状に形成されている。
ここで、上述の「ポスト部の直径」とは、前記ポスト部における先端部位の直径であってもよく、側面の特定部位の直径であってもよい。
また、特に、本実施形態では、スナップ部材として雌型のものを例示するが、これに限られず、雄型スナップ部材を用いても良い。
(スナップ部材10の構成)
図1は本発明の実施形態1に係るスナップ部材10の裏面側の斜視図を、図2はスナップ部材10の断面図を示す。また、図3は、ポスト部31差し込み前の、スナップ取付部材30、可撓性基材20、及び、スナップ部材10の断面図を示す。
次に、本発明の実施形態1に係るスナップ部材10の、衣服の生地等の可撓性基材20への取り付け方法について図を用いて詳細に説明する。また、本実施形態では、スナップ取付部材30及びスナップ部材10を、スナップ部材取り付け装置(不図示)を用いて可撓性基材20に取り付ける方法について例示的に説明する。
続いて、可撓性基材20を緊張させてスナップ取付部材30とスナップ部材10との間に介在させた状態で、スナップ部材取り付け装置の打ち込み具を下降させる。打ち込み具が下降すると、図3に示すように、緊張した可撓性基材20を挟んだ両側において、スナップ取付部材30のポスト部31とスナップ部材10の差込部16とが対向する。
続いて、さらに打ち込み具を下降させると、図5に示すように、差込部16の差込口17が塑性変形により若干開くと共に、壁部19が押される。ここで、壁部19は、その先端から基端にかけて半径方向の肉厚がしだいに減少する形状に形成されているため、基端が先端に比べて肉厚が小さく、変形しやすい。従って、押された壁部19は、基端を中心にして傾き、先端から溝部18内へ入り込むようにして変位する。このとき、溝部18が、壁部19の変位量を収容することで、ポスト部からの押圧力を吸収する。このように、ポスト部31の差し込みに伴って生じる部材本体11の変位を溝部18が吸収するため、部材本体11の可撓性基材20に対する移動が抑制され、取り付け位置が安定する。
この状態でさらに打ち込み具が下降を続けることにより、打ち込み具の軸芯部に設けられたハンマーがポスト部31の先端部を打撃して拡開変形させる(フランジ付けする)ことによって、図7に示すように、スナップ取付部材30とスナップ部材10とが加締め止めにより可撓性基材20に固定される。
スナップ部材は、実施形態1に記載したものに限らず、例えば、以下に説明する実施形態2に係る構成であってもよい。
