- the sheet 1, the mounting member 30, and the lower mold 40 for supporting the mounting member 30 are shown.
- the lower mold 40 has a support recess 41 that can receive the base 31 of the mounting member 30 on the upper surface thereof. When the mounting member 30 is placed in the support recess 41, the axis of the shaft portion 32 of the mounting member 30 is aligned. It matches the axis of the upper mold 10B.
- the upper die 10 ⁇ / b> B is lowered (the lower die 40 may rise), and the shaft portion 32 of the attachment member 30 is accommodated in the expansion allowance portion 13 ⁇ / b> B of the working bottom portion 11 ⁇ / b> B.
- the expansion action surface 131b crushes the tip 32d of the shaft portion 32 as shown in FIG.
- the shaft portion 32 expands radially outward on the opening 24A on the bottom surface 23A ′ of the bottom portion 23A of the female snap button 20A, and a part of the outer expansion allowance portion is crushed while being received by the peripheral recess 15B.
- a rib 322b is formed in the peripheral recess 15B, and the female snap button 20A is fixed on the seat 1.
- the shaft portion 32 of the attachment member 30 is collected in the expansion allowance portion 13B even when the sheet 1 is thick. Since it can be expanded to the recess 15B and deformed relatively outwardly in the deformation direction, a necessary button mounting force can be secured. Even when the sheet 1 is thin, the deformation of the shaft portion 32 outward in the radial direction is dispersed in the circumferential direction, and the force required for caulking is small, so the load on the press machine does not increase.
- an edge 151 that defines the boundary between the peripheral recess 15A and the expansion allowance 13A is formed between the peripheral recess 15A and the expansion allowance 13A of the upper mold 10A shown in FIG.
- the belt-like bottom surface shown in FIG. 5 has a slope shape that gradually rises and slopes toward the expansion allowance portion 13A, and the end of the belt-like bottom surface portion is integrated and continuous with the annular recess 133a without forming the edge 151.
- the outer end portion of the rib 322a does not have to be located on the outer periphery of the base portion 321a, and the outer end portion of the rib 322a may be located inside the outer periphery of the base portion 321a.
- the extended peripheral surface 132c may also be used. In this case, the expansion action surface 131c may have a flat surface or a curved surface.
- the extended peripheral surface 132c can be a curved surface or an inclined surface that expands in a concave shape from the expansion action surface 131c toward the peripheral portion 12C.
- the thickness of the rib 322b of the end portion 32b of the shaft portion 32 is formed thinner than that of the base portion 321b.
- the ribs 322c of the end portion 32c of the shaft portion 32 and the base portion 321c may have the same thickness.
- the member 100 and the member 101 shown in FIG. 16 may be integrally formed.
- the expansion action surface 131b of the upper mold 10B is shown as a plane perpendicular to the side wall portion 132b in the drawing, but the cross section is reversed U depending on the shape of the button to be manufactured. You may have a character-shaped curved surface.

Description
-ボタン-
本発明の第1の実施の形態に係るボタンは、図1~図3に示すように、第1主面1a及び第1主面1aと対向する第2主面1bを有するシート1の第1主面1a上に配置され、開口24Aを備えるボタン本体20と、第2主面1b上に配置された基部31及び基部31から突出し第2主面1bから開口24Aを通って第1主面1a側へ貫通する軸部32を備える取付部材30とを備える。
第1の実施の形態に係るボタン取付用上金型10A(以下単に「上金型10A」ともいう)は、図5に示すように、軸部32(図7参照)を加締めるために軸部32の先端32dと接触する作用底部11Aを備える。作用底部11Aは、作用底部11Aの外周を定義する周縁部12A上に配置された複数の周縁凹部15Aと、周縁部12Aの内側(作用底部11A中央)に配置された拡張許容部13Aと、周縁部12Aの周方向に沿って互いに離間して設けられた複数の周縁凸部14Aとを備える。
次に、図5のボタン取付用上金型10Aを使用しての雌スナップボタン20Aをシート1へ取り付ける取付工程を説明する。図7は、雌スナップボタン20Aをシート1の一例である生地に取り付ける直前の主要構成の上下方向(軸方向)の配置状態を示し、上から、ボタン取付用上金型10A、雌スナップボタン20A、シート1、取付部材30、及び、取付部材30を支持させる下金型40を示す。下金型40は、その上面に、取付部材30の基部31を受け入れ可能な支持凹部41を有し、この支持凹部41に取付部材30を載置すると、取付部材30の軸部32の軸線が上金型10Aの軸線と合致するようになっている。

本発明の第2の実施の形態に係るボタンは、図11~図13に示すように、第1主面1a及び第1主面1aと対向する第2主面1bを有するシート1の第1主面1a上に配置され、第1主面1a上に開口24Aを備えるボタン本体20Aと、第2主面1b上に配置された基部31及び基部31から突出し、第2主面1bから開口24Aを通って第1主面1a側へ貫通する軸部32を備える取付部材30とを備える。
第2の実施の形態に係るボタン取付用上金型10B(以下単に「上金型10B」ともいう)は、図14に示すように、軸部32を加締めるために軸部32の先端32d(図16参照)と接触する作用底部11Bを備える。作用底部11Bは、作用底部11Bの外周を定義する周縁部12B上に沿って配置された複数の周縁凸部14Bと、複数の周縁凸部14Bの間に、周縁部12Bに沿ってそれぞれ離間して配置された周縁凹部15Bと、周縁部12Bの内側(作用底部11B中央)に配置され、加締め時に軸部32の半径方向外側への拡張を許容する拡張許容部13Bとを備える。
次に、図14のボタン取付用上金型10Bを使用しての雌スナップボタン20Aのシート1への取付工程を説明する。図16は、雌スナップボタン20Aをシート1の一例である生地に取り付ける直前の主要構成の上下方向(軸方向)の配置状態を示し、上から、ボタン取付用上金型10B、雌スナップボタン20A、シート1、取付部材30、及び、取付部材30を支持させる下金型40を示す。下金型40は、その上面に、取付部材30の基部31を受け入れ可能な支持凹部41を有し、この支持凹部41に取付部材30を載置すると、取付部材30の軸部32の軸線が上金型10Bの軸線と合致するようになっている。
上記のように本発明の実施の形態を記載したが、この開示の一部をなす論述及び図面は、この発明を限定するものであると理解すべきではない。例えば、図5に示す上金型10Aの周縁凹部15Aと拡張許容部13Aとの間には、周縁凹部15Aと拡張許容部13Aとの境界を定義する縁151が形成されているがこれに限定されない。例えば、図5に示す帯状の底面を、拡張許容部13Aへ向けて徐々に上り傾斜させる斜面形状とし、帯状の底面部分の端を、縁151を形成することなく環状凹部133aと一体且つ連続するように形成してもよい。
