Abstract

A cylindrical protrusion section (14, 54, 74) is provided around a mounting opening (13, 53, 73) in a base section (11, 51, 71) of a male snap button (10, 50) or a female snap button (70). When mounting the male snap button (10, 50) or the female snap button (70) to cloth (1) by means of a button mounting member (20), a post section (22) of the button mounting member (20) is caused to penetrate through the cloth (1) and then to pass through the mounting opening (13, 53, 73) of the male snap button (10, 50) or the female snap button (70), and after that the post section (22) is staked by an upper die (30, 60, 80). In the staking operation, the protrusion section (14, 54, 74) of the male snap button (10, 50) or the female snap button (70) is crushed between the post section (22) and the base section (11, 51, 71), and this causes a part of the load applied to the male snap button (10, 50) or the female snap button (70) to be absorbed by the deformation of the protrusion section (14, 54, 74).

　本発明は、雄スナップボタン取付方法、雄スナップボタン及び雄スナップボタン構成体、並びに雌スナップボタン取付方法、雌スナップボタン及び雌スナップボタン構成体に関し、特に、生地を貫通したボタン取付部材のポスト部を上金型で加締めることにより生地に取り付ける雄スナップボタン及び雌スナップボタンの生地への取り付け方法と、そのような雄スナップボタン及び雌スナップボタンと、そのような雄スナップボタン及び雌スナップボタンとボタン取付部材との組合せから成る雄スナップボタン構成体及び雌スナップボタン構成体とに関する。 The present invention relates to a male snap button mounting method, a male snap button and a male snap button structure, and a female snap button mounting method, a female snap button and a female snap button structure, and in particular, a post portion of a button mounting member penetrating a cloth. A male snap button and a female snap button to be attached to the fabric by crimping with a top mold, such a male snap button and a female snap button, such a male snap button and a female snap button, The present invention relates to a male snap button structural body and a female snap button structural body, which are formed in combination with a button mounting member.
　スナップボタンを構成する一対の雄スナップボタン（雄スナップ）及び雌スナップボタン（雌スナップ）は、衣服や袋物等の合わせ目に広く使用されており、合わせ目をなす一方の生地に雄スナップが、他方の生地に雌スナップが取り付けられ、雄スナップの突起部を雌スナップの突起受入部に係合及び脱係合することにより、合わせ目が閉開される。雄スナップ及び雌スナップそれぞれの生地への取り付けは、一般に、ボタン取付部材のポスト部を生地に貫通させ、次いで雄スナップ又は雌スナップの基部の中央に設けられた取付用開口に通した後、上金型のパンチによりポスト部を雄スナップ又は雌スナップの基部上で加締めることによって行われる。 A pair of male snap buttons (male snaps) and female snap buttons (female snaps) that make up the snap buttons are widely used in joints such as clothes and bags, and male snaps are on one of the fabrics that make up the joints. A female snap is attached to the other fabric, and the joint is closed and opened by engaging and disengaging the projection of the male snap with the projection receiving portion of the female snap. The male snap and the female snap are generally attached to the fabric by passing the post portion of the button mounting member through the fabric and then passing through the mounting opening provided at the center of the base of the male snap or the female snap. This is done by caulking the post portion on the base portion of the male snap or the female snap with a punch of a mold.
　しかしながら、上金型のパンチでボタン取付部材のポスト部を加締める際、雄スナップ又は雌スナップに大きい荷重がかかるため、雄スナップ及び雌スナップは、加締め時の大荷重に耐え得る強度で形成する必要があり、材料や寸法の選択範囲にある一定の制限があった。また、上金型には、余分な荷重を吸収するために円筒状の弾性部材が設けられており（例えば特開平１１－１８１２号公報参照）、その分、コストが嵩んだ。 However, when the post part of the button mounting member is crimped with the punch of the upper mold, a large load is applied to the male snap or the female snap. Therefore, the male snap and the female snap are formed with a strength that can withstand the large load during the crimping. There was a certain limitation in the selection range of materials and dimensions. Further, the upper mold is provided with a cylindrical elastic member to absorb an excessive load (see, for example, Japanese Patent Laid-Open No. 11-1812), and the cost is increased accordingly.
特開平１１－１８１２号公報Japanese Patent Laid-Open No. 11-1812
　本発明は、上記のような問題点に着目してなされたものであり、その目的は、ボタン取付部材のポスト部の加締め時に荷重の一部を吸収することができ、これにより、雄スナップボタン又は雌スナップボタンの製品強度を下げたり、上金型の弾性部材を不要にすることができる雄スナップボタン取付方法、雄スナップボタン及び雄スナップボタン構成体、並びに雌スナップボタン取付方法、雌スナップボタン及び雌スナップボタン構成体を提供することにある。 The present invention has been made paying attention to the above-described problems, and the purpose thereof is to absorb a part of the load when the post portion of the button mounting member is caulked, and thereby, the male snap.

　図２は、雄スナップ１０を生地１に取り付ける際に使用するボタン取付部材２０、上金型３０及び下金型４０と、雄スナップ１０及び生地１の取り付け時における上下方向の配置状態を示す。なお、雄スナップ１０とボタン取付部材２０は本発明に係る雄スナップボタン構成体の一実施形態を成す。ボタン取付部材２０は、アセタール樹脂製であり、略円板状のベース部２１と、ベース部２１から上方にベース部２１と同心状に突出するポスト部２２とを備える。ポスト部２２は上方へと先細りし、尖った先端２３を有する。上金型３０は、図示しないスナップボタン取付用プレス機の昇降部に連結され、環状のパンチガイド３１と、パンチガイド３１の軸線に沿う中央孔３２を通って昇降される（図示される下方部分が）円柱状で鋼製のパンチ３４とを含む。パンチガイド３１の底部には、取り付け時に雄スナップ１０の突起部１２を受け入れて雄スナップ１０を保持するための、上方に凹となるスナップ保持部３３が設けられ、突起部１２は、その拡張部１２’が弾性的に若干縮径されてスナップ保持部３３と係合する。また、パンチ３４の底部には、水平で環状の底面３５と、底面３５の半径方向内側で上方に凹となる、ボタン取付部材２０のポスト部２２を加締めるための加締め凹部３６とが形成される。パンチ３４の底部の外径は、雄スナップ１０の***部１４の外径よりも大きく、加締め凹部３６の直径は、雄スナップ１０の***部１４の内径とほぼ同じである（図３参照）。下金型４０は、上面にボタン取付部材２０のベース部２１を合致的に受ける凹状のベース載置部４１を有する。ベース載置部４１にベース部２１が載置されたボタン取付部材２０は、ポスト部２２の軸線がパンチ３４の軸線と一致して上金型３０と同心となる。 FIG. 2 shows a button mounting member 20, an upper mold 30 and a lower mold 40 that are used when the male snap 10 is attached to the cloth 1, and an arrangement state in the vertical direction when the male snap 10 and the cloth 1 are attached. The male snap 10 and the button mounting member 20 constitute an embodiment of the male snap button structure according to the present invention. The button mounting member 20 is made of acetal resin, and includes a substantially disc-shaped base portion 21 and a post portion 22 that protrudes from the base portion 21 concentrically with the base portion 21. The post portion 22 tapers upward and has a pointed tip 23. The upper die 30 is connected to an elevating part of a snap button attaching press (not shown), and is moved up and down through an annular punch guide 31 and a central hole 32 along the axis of the punch guide 31 (lower part shown in the figure). A) a cylindrical punch 34 made of steel. The bottom of the punch guide 31 is provided with a snap holding portion 33 that is recessed upward to receive the protrusion 12 of the male snap 10 and hold the male snap 10 at the time of attachment. 12 'is elastically slightly reduced in diameter and engaged with the snap holding portion 33. Further, a bottom surface of the punch 34 is formed with a horizontal and annular bottom surface 35 and a caulking recess 36 for caulking the post portion 22 of the button mounting member 20 that is recessed upward in the radial direction of the bottom surface 35. Is done. The outer diameter of the bottom part of the punch 34 is larger than the outer diameter of the raised part 14 of the male snap 10, and the diameter of the caulking recessed part 36 is substantially the same as the inner diameter of the raised part 14 of the male snap 10 (see FIG. 3). . The lower mold 40 has a concave base mounting portion 41 that receives the base portion 21 of the button mounting member 20 on the upper surface. The button mounting member 20 on which the base portion 21 is placed on the base placement portion 41 is concentric with the upper mold 30 so that the axis of the post portion 22 coincides with the axis of the punch 34.
　次に、本発明に係る雄スナップボタン取付方法の一実施形態として、雄スナップ１０を生地１に取り付ける工程について説明する。図３は、パンチガイド３１のスナップ保持部３３に突起部１２が係合して雄スナップ１０を保持した上金型３０を、下金型４０のベース載置部４１に載置されたボタン取付部材２０に対し、雄スナップ１０とボタン取付部材２０間に生地１を挟んで降下させ、ボタン取付部材２０のポスト部２２が生地１を突き上げている状態を示す。この時点で、パンチ３４の底面３５は雄スナップ１０の***部１４の頂端に突き当たっている。この状態から上金型３０を更に降下させると、図４に示すように、ポスト部２２が生地１を貫通し、次いで雄スナップ１０の開口１３を通り、ポスト部２２の先端２３がパンチ３４の加締め凹部３６に入り込んで突き当たる。この時点ではまた、生地１が雄スナップ１０の基部１１とボタン取付部材２０のベース部２１との間で挟み付けられて圧縮される。この状態からパンチ３４を降下させることにより、加締め工程が次に述べるように行われる。 Next, the process of attaching the male snap 10 to the fabric 1 will be described as one embodiment of the male snap button attaching method according to the present invention. FIG. 3 shows a button attachment in which the upper mold 30 holding the male snap 10 by engaging the protrusion 12 with the snap holding section 33 of the punch guide 31 is mounted on the base mounting section 41 of the lower mold 40. The member 20 is lowered with the fabric 1 sandwiched between the male snap 10 and the button mounting member 20 and the post portion 22 of the button mounting member 20 pushes up the fabric 1. At this point, the bottom surface 35 of the punch 34 is in contact with the top end of the raised portion 14 of the male snap 10. When the upper die 30 is further lowered from this state, as shown in FIG. 4, the post portion 22 penetrates the cloth 1, then passes through the opening 13 of the male snap 10, and the tip 23 of the post portion 22 is formed on the punch 34. It enters into the caulking recess 36 and hits it. At this time, the fabric 1 is also sandwiched between the base portion 11 of the male snap 10 and the base portion 21 of the button mounting member 20 and compressed. By lowering the punch 34 from this state, the caulking process is performed as described below.
　加締め工程の初期状態において、図５に示すように、パンチ３４の加締め凹部３６がポスト部２２を先端２３から潰し始めると共に、パンチ３４の底面３５が雄スナップ１０の***部１４をその上端側が半径方向外側に逸れるように変形させ始める。この状態からパンチ３４が更に降下すると、図６に示すように、ポスト部２２が潰れて加締め凹部３６を満たし、更に半径方向外側へと膨張し始める。このポスト部２２の半径方向外側への膨張は、パンチ３４の底面３５からの押圧と相俟って雄スナップ１０の***部１４を更に半径方向外側へと倒す。図７は、加締め工程が完了した状態を示す。この状態において、雄スナップ１０の***部１４は半径方向外側に倒されて基部１１の上面１１’上に押し潰される。この潰れた***部１４’上にポスト部２２の半径方向外側に膨張した部分２２’が重なるように加締め付けられる。 In the initial state of the caulking process, as shown in FIG. 5, the caulking recess 36 of the punch 34 begins to crush the post portion 22 from the tip 23, and the bottom surface 35 of the punch 34 pushes the raised portion 14 of the male snap 10 to its upper end. Begin to deform so that the sides deviate radially outward. When the punch 34 is further lowered from this state, as shown in FIG. 6, the post portion 22 is crushed, fills the caulking concave portion 36, and starts to expand further outward in the radial direction. The expansion of the post portion 22 outward in the radial direction, combined with the pressing from the bottom surface 35 of the punch 34, further tilts the raised portion 14 of the male snap 10 outward in the radial direction. FIG. 7 shows a state where the caulking process is completed. In this state, the raised portion 14 of the male snap 10 is tilted outward in the radial direction and crushed on the upper surface 11 ′ of the base 11. The crushed raised portion 14 ′ is crimped so that the portion 22 ′ expanded outward in the radial direction of the post portion 22 overlaps.
　以上の加締め工程において、雄スナップ１０では、パンチ３４からの圧力の一部を***部１４を変形させて吸収することができるため、基部１１にかかる荷重を低減することができ、これにより、雄スナップ１０の製品強度を下げることが可能となるため、雄スナップ１０の材料や寸法の選択範囲が拡大する。また、基部１１にかかる荷重を軽減するために従来から上金型に設けられている円筒状の弾性部材（ばね）を不要とすることができる。 In the above caulking process, since the male snap 10 can absorb a part of the pressure from the punch 34 by deforming the raised portion 14, the load applied to the base 11 can be reduced. Since the product strength of the male snap 10 can be lowered, the selection range of the material and dimensions of the male snap 10 is expanded. Further, it is possible to eliminate the need for a cylindrical elastic member (spring) conventionally provided in the upper mold in order to reduce the load applied to the base 11.
　図８は雄スナップ及び上金型の変形例を示す。この雄スナップ５０は、***部５４の高さ以外は上述した雄スナップ１０と同じであり、また、上金型６０は、パンチ６４の底面６５が平坦で加締め凹部が無い点以外は上述した上金型３０と同じである。そのため、雄スナップ５０及び上金型６０以外の構成は、図２等と同じ参照番号を用いる。雄スナップ１０の***部５４の高さは突起部５２と同じである。生地１を貫通し次いで雄スナップ５０の開口５３を通ったボタン取付部材２０のポスト部２２は、上金型６０のパンチ６４の底面６５により図８の状態から図９に示すように軸方向に潰れかつ半径方向外側に膨張するように加締められる。この際、雄スナップ５０の***部５４は、パンチ６４と変形するポスト部２２によって基部５１上に押し潰される（変形後の***部を符号５４’で示す）。 Fig. 8 shows a modification of the male snap and upper die. The male snap 50 is the same as the male snap 10 described above except for the height of the raised portion 54, and the upper mold 60 is the same as that described above except that the bottom surface 65 of the punch 64 is flat and has no caulking recess. The same as the upper mold 30. Therefore, configurations other than the male snap 50 and the upper mold 60 use the same reference numbers as in FIG. The height of the raised portion 54 of the male snap 10 is the same as that of the protruding portion 52. The post portion 22 of the button mounting member 20 that has passed through the fabric 1 and then passed through the opening 53 of the male snap 50 is axially moved from the state of FIG. 8 to the axial direction as shown in FIG. 9 by the bottom surface 65 of the punch 64 of the upper mold 60. It is crimped to collapse and expand radially outward. At this time, the raised portion 54 of the male snap 50 is crushed on the base portion 51 by the punch 64 and the deformed post portion 22 (the raised portion after deformation is indicated by reference numeral 54 ′).
　図１０は、本発明に係る雌スナップボタンの一実施形態である雌スナップボタン（以下、単に「雌スナップ」という）７０を含む図２と同様の配置状態を示し、生地１、ボタン取付部材２０及び下金型４０は図２等と実質的に同じものであるため、同じ参照番号を付して説明を省略する。なお、雌スナップ７０とボタン取付部材２０は本発明に係る雌スナップボタン構成体の一実施形態を成す。雌スナップ７０は、略円板状の基部７１と、基部７１から上方に基部７１と同心状に突出し、雄スナップ１０、５０の突起部１２、５２を着脱可能に受け入れる突起受入部７５を規定する円筒状の周側部７２と、周側部７２の上端部から半径方向外側に延びるスカート状のフランジ部７６と、基部７１における周側部５２より半径方向内側の中央部に開けられた円形の開口７３と、開口７３の周囲において基部７１から上方に***する円筒状の***部７４とを有する。周側部７２の上端部には、雄スナップ１０、５０の突起部１２、５２との離脱抵抗を高めるため、半径方向内側に拡張する拡張部７２’が設けられる。***部７４の基部７１の上面からの高さは、周側部７２の高さの１／２よりも若干高く設定されるが、これに限らず、例えば周側部７２と同じ高さに設定することができる。 FIG. 10 shows an arrangement similar to FIG. 2 including a female snap button (hereinafter simply referred to as “female snap”) 70 which is an embodiment of the female snap button according to the present invention. Since the lower mold 40 is substantially the same as that shown in FIG. 2 and the like, the same reference numerals are assigned and description thereof is omitted. The female snap 70 and the button attachment member 20 constitute an embodiment of the female snap button structure according to the present invention. The female snap 70 defines a substantially disc-shaped base 71 and a protrusion receiving portion 75 that protrudes upward from the base 71 concentrically with the base 71 and removably receives the protrusions 12 and 52 of the male snaps 10 and 50. A cylindrical peripheral side portion 72, a skirt-like flange portion 76 extending radially outward from the upper end of the peripheral side portion 72, and a circular shape opened in a central portion radially inward from the peripheral side portion 52 in the base portion 71. It has the opening 73 and the cylindrical protruding part 74 which protrudes upward from the base 71 around the opening 73. The upper end portion of the peripheral side portion 72 is provided with an extended portion 72 ′ that extends radially inward in order to increase the separation resistance with the protrusions 12 and 52 of the male snaps 10 and 50. The height of the raised portion 74 from the upper surface of the base portion 71 is set to be slightly higher than ½ of the height of the peripheral side portion 72, but is not limited thereto, and is set to the same height as the peripheral side portion 72, for example. can do.
　上金型８０は、環状のパンチガイド８１と、パンチガイド８１の軸線に沿う中央孔８２を通って昇降される（図示される下方部分が）円柱状のパンチ８４とを含む。パンチガイド８１の底部には、取り付け時に雌スナップ７０の突起受入部７５に入り込んで雌スナップ７０を保持するための、下方に突出する円筒状のスナップ保持部８３が設けられる。周側部７２は、その拡張部７２’が弾性的に若干拡径してスナップ保持部８３と係合する。また、パンチ８４の底部には、水平で環状の底面８５と、底面８５の半径方向内側で上方に凹となる、ボタン取付部材２０のポスト部２２を加締めるための加締め凹部８６とが形成される。パンチ８４の底部の外径は、雌スナップ７０の***部７４の外径よりも大きく、加締め凹部８６の直径は、雌スナップ７０の***部７４の内径とほぼ同じである。 The upper mold 80 includes an annular punch guide 81 and a cylindrical punch 84 that is moved up and down (a lower portion shown in the drawing) through a central hole 82 along the axis of the punch guide 81. At the bottom of the punch guide 81, there is provided a cylindrical snap holding portion 83 projecting downward to enter the protrusion receiving portion 75 of the female snap 70 and hold the female snap 70 when attached. The peripheral side portion 72 is engaged with the snap holding portion 83 with its expanded portion 72 ′ elastically slightly expanded in diameter. In addition, a bottom surface of the punch 84 is formed with a horizontal and annular bottom surface 85 and a caulking recess 86 for caulking the post portion 22 of the button mounting member 20 that is recessed upward in the radial direction of the bottom surface 85. Is done. The outer diameter of the bottom of the punch 84 is larger than the outer diameter of the raised portion 74 of the female snap 70, and the diameter of the caulking recess 86 is substantially the same as the inner diameter of the raised portion 74 of the female snap 70.
　本発明に係る雌スナップボタン取付方法の一実施形態としての、雌スナップ７０をボタン取付部材２０を用いて生地１に取り付け工程は、パンチガイド８１のスナップ保持部８３を突起受入部７５に係合させて雌スナップ７０を保持した上金型８０を降下させて、雄スナップ１０の取り付け工程と同様に行われる。すなわち、ボタン取付部材２０のポスト部２２が生地１を貫通し次いで雌スナップ７０の開口７３を通った後、パンチ８４を降下させて、雌スナップ７０の***部７４を変形させながらポスト部２２を図１１に示すように加締める。この場合も、***部７４は変形するポスト部２２と雌スナップ７０の基部７１との間で押し潰され（変形後の***部を符号７４’で示す）、パンチ８４からの圧力の一部を吸収することができ、基部７１にかかる荷重を低減することができる。 As an embodiment of the female snap button attachment method according to the present invention, the step of attaching the female snap 70 to the fabric 1 using the button attachment member 20 engages the snap holding portion 83 of the punch guide 81 with the protrusion receiving portion 75. Then, the upper mold 80 holding the female snap 70 is lowered, and the same process as that of the male snap 10 is performed. That is, after the post portion 22 of the button mounting member 20 passes through the cloth 1 and then passes through the opening 73 of the female snap 70, the punch 84 is lowered to deform the raised portion 74 of the female snap 70 while deforming the post portion 22. It crimps as shown in FIG. Also in this case, the raised portion 74 is crushed between the deformed post portion 22 and the base portion 71 of the female snap 70 (the raised raised portion is indicated by reference numeral 74 ′), and a part of the pressure from the punch 84 is reduced. Therefore, the load applied to the base 71 can be reduced.
