Description

本発明は、紐先留具及びその製造方法に関する。さらに詳しく説明すると、本発明は、取付箇所が目立たない紐留具及びその製造方法に関する。 The present invention relates to a string tip fastener and a method for manufacturing the same. More specifically, the present invention relates to a string fastener in which the attachment portion is inconspicuous and a method for manufacturing the same.

丸紐、コード、組紐、より紐又はスピンドル紐その他の編んで織り上げた紐は、切り放しだとばらけるため、その先端にいわゆるチップ加工が施される。チップ加工には、セルチップ加工、金属チップ加工及び弾丸チップ加工等がある。セルチップ加工は、紐の先端に熱収縮する合成樹脂製のフィルムを巻き付ける加工方法である。金属チップ加工は、紐の先端に板状の金属をかしめて巻き付ける加工方法である。弾丸チップ加工は、紐の先端に板状の金属をかしめて巻き付けて、さらにその先端を丸くする加工方法である。 Round cords, cords, braided cords, twisted cords, spindle cords, and other knitted and woven cords are separated when left uncut, so so-called chip processing is applied to the tips. Chip processing includes cell chip processing, metal chip processing, bullet chip processing, and the like. Cell chip processing is a processing method in which a heat-shrinkable synthetic resin film is wound around the tip of a string. Metal chip processing is a processing method in which a plate-shaped metal is crimped and wound around the tip of a string. Bullet tip processing is a processing method in which a plate-shaped metal is crimped and wound around the tip of a string, and the tip is further rounded.

また、編んで織り上げた紐の先端に、ポリエチレンのチューブを収縮させるＥＶ加工や、アイロン等でシュリンクフィルムを収縮させる加工方法もある。さらに、編んで織り上げた紐の先端に、ワニ口等の先止め金具を噛ませて取り付ける加工方法もある。編んで織り上げた紐の先端は、これらの加工方法が施されてばらけることを防ぎ、孔等にも通しやすくなる。このように、従来から様々な方法で紐の先端がばらけないための加工がされているが、特許文献を基に従来の技術を説明する。 There are also EV processing methods for shrinking a polyethylene tube at the tip of a knitted and woven string, and processing methods for shrinking a shrink film with an iron or the like. Further, there is also a processing method in which the tip of the knitted and woven string is attached by biting a tip stopper such as an alligator mouth. The tip of the knitted and woven string is subjected to these processing methods to prevent it from loosening and to easily pass through holes and the like. As described above, processing has been conventionally performed so that the tip of the string does not come apart by various methods, but the conventional technique will be described based on the patent document.

紐本体の周囲に塗布した樹脂剤を型枠に嵌め込み、加熱・加圧して硬化させた筒状のセルチップが取り付けられた紐の技術が知られている（例えば、特許文献１参照）。また、端部に液状のシリコーン樹脂を付与し、成形金型内に収めて加熱及び加圧することによって熱硬化したソフトセルチップを設けた紐の技術が知られている（例えば、特許文献２参照）。セルチップを用いることなく、紐部材の端部を細径化及び硬質化すると同時に、恒久的なほつれ止めを行えるようにした、加工の容易な紐端部の加工装置及び該装置を用いる加工方法の技術が知られている（例えば、特許文献２参照）。 A technique is known in which a resin agent applied around a string body is fitted into a mold, and a tubular cell tip that is heated and pressurized to be cured is attached (see, for example, Patent Document 1). Further, there is known a technique of a string provided with a soft cell chip that is heat-cured by applying a liquid silicone resin to an end portion, storing it in a molding die, and heating and pressurizing it (see, for example, Patent Document 2). ). An easy-to-process string end processing device and a processing method using the device, which makes it possible to reduce the diameter and harden the end of the string member and at the same time permanently prevent fraying without using a cell tip. The technique is known (see, for example, Patent Document 2).

しかし、特許文献１及び２に示されたセルチップは、単に紐の先端を合成樹脂で固めているだけであって、意匠性に乏しいという問題点があった。特許文献３に示された紐端部は、硬質化されているのみであって、意匠性に乏しいという問題点があった。また、金属チップ加工及び弾丸チップ加工等は、セルチップ加工に比べると金属特有の高級感があるが、かしめて固定している箇所やつなぎ目等が外見上明らかであり、歪みも形成されてしまうため意匠性に乏しいという問題点があった。さらに、かしめているため先端部分を平たくすることが困難であるという問題点があった。 However, the cell chips shown in Patent Documents 1 and 2 have a problem that the tip of the string is simply hardened with a synthetic resin and the design is poor. The string end portion shown in Patent Document 3 has a problem that it is only hardened and has poor design. In addition, metal chip processing and bullet chip processing have a high-class feeling peculiar to metal compared to cell chip processing, but the points where they are crimped and fixed, the joints, etc. are apparently clear, and distortion is also formed. There was a problem that it lacked design. Further, there is a problem that it is difficult to flatten the tip portion because it is crimped.

本発明は、このような社会的、技術的背景に基づいたものであり、次のような目的を達成する。本発明の目的は、意匠性に優れた紐留具及びその製造方法を提供することにある。また、本発明の目的は、金属特有の高級感を持ちながら固定されている箇所が外見上わかりにくい紐留具及びその製造方法を提供することにある。 The present invention is based on such a social and technical background, and achieves the following objects. An object of the present invention is to provide a string fastener having excellent design and a method for manufacturing the same.

Embodiment 1 of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external view showing a cord fastener 1 according to the first embodiment of the present invention. FIG. 2A is an enlarged view showing an enlarged state of the string fastener 1, and FIG. 2B is a cross-sectional view showing a state in which the string fastener 1 is cut. FIG. 3 is a diagram showing a process of manufacturing the string fastener 1.

図１及び２に示すように、紐留具１は、仮留部１０、本体部２０、縮径部３０及び装飾部４０とから構成されている。紐留具１は、本体部２０、縮径部３０及び装飾部４０が一体に形成されている。仮留部１０は、紐部Ｓに直接で取り付けられている。本体部２０は、仮留部１０を介して紐部Ｓに取り付けられている。紐部Ｓは、衣類等に形成された紐通し穴に挿通して用いられる丸紐等の周知の紐状部材である。紐部Ｓは、所定の力が加えられると弾性変形する外径４ｍｍのポリエステル製のスピンドル紐である。 As shown in FIGS. 1 and 2, the string fastener 1 is composed of a temporary fastening portion 10, a main body portion 20, a diameter reduction portion 30, and a decorative portion 40. In the string fastener 1, the main body portion 20, the diameter reduction portion 30, and the decorative portion 40 are integrally formed. The temporary fastening portion 10 is directly attached to the string portion S. The main body portion 20 is attached to the string portion S via the temporary fastening portion 10. The string portion S is a well-known string-like member such as a round string used by inserting it into a string through hole formed in clothing or the like. The string portion S is a polyester spindle string having an outer diameter of 4 mm that elastically deforms when a predetermined force is applied.

〔仮留部１０〕
図２（ｂ）に示すように、仮留部１０は、紐部Ｓの端部がばらけることを防ぐための部材であり、紐部Ｓの端部の外周に取り付けられている。仮留部１０は、紐部Ｓの端部に熱収縮するセルロース等の合成樹脂製の仮留フィルム１５を巻き付けて熱をかけて収縮させて形成されている（図３参照）。仮留部１０は、仮留フィルム１５が収縮されて筒状になり、紐部Ｓの端部をまとめて固定するため、紐部Ｓの端部がばらけることを防ぐ。仮留部１０は、長さ寸法が１５ｍｍに形成されている。仮留部１０は、紐部Ｓの端部を収縮しているため、仮留部１０の外径は、紐部Ｓの外径より小さい３ｍｍに形成されている。 [Temporary retaining part 10]
As shown in FIG. 2B, the temporary fastening portion 10 is a member for preventing the end portion of the string portion S from coming apart, and is attached to the outer periphery of the end portion of the string portion S. The temporary fixing portion 10 is formed by winding a temporary fixing film 15 made of a synthetic resin such as cellulose that heat-shrinks around the end of the string portion S and applying heat to shrink the temporary fixing portion 10 (see FIG. 3). In the temporary fixing portion 10, the temporary fixing film 15 is contracted to form a cylindrical shape, and the ends of the string portion S are fixed together, so that the ends of the string portion S are prevented from coming apart. The temporary fastening portion 10 is formed to have a length dimension of 15 mm. Since the temporary fastening portion 10 contracts the end portion of the string portion S, the outer diameter of the temporary fastening portion 10 is formed to be 3 mm, which is smaller than the outer diameter of the string portion S.

〔本体部２０〕
図１及び図２に示すように、本体部２０は、紐部Ｓの端部の装飾性を向上させるための部材であり、仮留部１０を全部覆うように紐部Ｓに取り付けられている。本体部２０は、高級感のある外観にするために真鍮等の金属で形成されている。本体部２０は、長さ寸法が２５ｍｍ外径が３．８ｍｍであり、内径が３．１ｍｍの略筒状に形成されている。本体部２０は、一端を開口する開口部２０ｈが形成され、他端を塞ぐ底部２０ｂが形成されている。本体部２０は、切削加工により形成されており、底部２０ｂが平らに形成されている。本体部２０は、その開口部２０ｈ側に縮径部３０が形成されている。本体部２０は、その内部に収納部２３が形成されており、仮留部１０を収納することができる。 [Main body 20]
As shown in FIGS. 1 and 2, the main body portion 20 is a member for improving the decorativeness of the end portion of the string portion S, and is attached to the string portion S so as to cover the entire temporary fastening portion 10. .. The main body 20 is made of a metal such as brass in order to give a high-class appearance. The main body 20 has a length dimension of 25 mm, an outer diameter of 3.8 mm, and an inner diameter of 3.1 mm, and is formed in a substantially cylindrical shape. The main body 20 is formed with an opening 20h that opens one end and a bottom 20b that closes the other end. The main body 20 is formed by cutting, and the bottom 20b is formed flat. The main body 20 has a reduced diameter portion 30 formed on the opening 20h side thereof. A storage portion 23 is formed inside the main body portion 20, and the temporary fastening portion 10 can be stored.

〔縮径部３０〕
図１及び図２に示すように、縮径部３０は、本体部２０を紐部Ｓに取り付けるための部材であり、本体部２０の開口部２０ｈに形成されている。縮径部３０は、開口部２０ｈに対して所定の力を加えて折り曲げて形成されている。縮径部３０は、他端側から一端側にかけて徐々に径が小さくなるようにテーパ状に形成されている。縮径部３０は、外径が３．６ｍｍであり、内径が２．９ｍｍの略筒状に形成されている。 [Diameter 30]
As shown in FIGS. 1 and 2, the reduced diameter portion 30 is a member for attaching the main body portion 20 to the string portion S, and is formed in the opening portion 20h of the main body portion 20. The reduced diameter portion 30 is formed by bending the opening 20h by applying a predetermined force. The reduced diameter portion 30 is formed in a tapered shape so that the diameter gradually decreases from the other end side to the one end side. The reduced diameter portion 30 is formed in a substantially cylindrical shape having an outer diameter of 3.6 mm and an inner diameter of 2.9 mm.

図１及び２に示すように、縮径部３０の外径は本体部２０の外径より小さく形成されており、縮径部３０の内径は本体部２０の内径より小さく形成されている。縮径部３０の内径は紐部Ｓの外径より小さく形成されているため、縮径部３０は紐部Ｓに食い込む。縮径部３０の内径は仮留部１０の外径より小さく形成されているため、収納部２３に収納された仮留部１０は本体部２０から抜けない。本体部２０の縮径部３０は、弾性変形した紐部Ｓに食い込んでいる状態なので、紐部Ｓに対して回転自在である。 As shown in FIGS. 1 and 2, the outer diameter of the reduced diameter portion 30 is formed to be smaller than the outer diameter of the main body portion 20, and the inner diameter of the reduced diameter portion 30 is formed to be smaller than the inner diameter of the main body portion 20. Since the inner diameter of the reduced diameter portion 30 is formed to be smaller than the outer diameter of the string portion S, the reduced diameter portion 30 bites into the string portion S. Since the inner diameter of the reduced diameter portion 30 is formed to be smaller than the outer diameter of the temporary fastening portion 10, the temporary fastening portion 10 housed in the storage portion 23 cannot be removed from the main body portion 20. Since the reduced diameter portion 30 of the main body portion 20 is in a state of biting into the elastically deformed string portion S, it is rotatable with respect to the string portion S.

〔装飾部４０〕
図１及び２に示すように、本体部２０には、本体部２０の装飾性を向上させるための装飾部４０が形成されている。装飾部４０は、本体部２０に形成されており、切削加工により削り取られた溝である。装飾部４０は、本体部２０の他端を沿うように一周にわたって削り取られて形成されている。装飾部４０は、切削加工によって本体部２０を削り取って形成されているため、一定の幅であり、一定の深さに形成されている。 [Decorative part 40]
As shown in FIGS. 1 and 2, the main body 20 is formed with a decorative portion 40 for improving the decorativeness of the main body 20. The decorative portion 40 is a groove formed in the main body portion 20 and cut off by cutting. The decorative portion 40 is formed by being scraped off around the other end of the main body portion 20. Since the decorative portion 40 is formed by cutting the main body portion 20 by cutting, it has a constant width and a constant depth.

紐留具１は、本体部２０が切削加工によって歪みのない滑らかな外観に形成されているため、装飾性に優れている。紐留具１は、本体部２０全体をかしめて紐部Ｓに固定されてるのではなく、端部のみが曲げられているため、固定されている箇所が外見上わかりにくい。紐留具１は、本体部２０全体をかしめていないため、つなぎ目が外観上に表れることもないうえに、先端である底部２０ｂを平らに形成することができるため、装飾性にすぐれている。紐留具１は、接着不良による剥がれやのりのはみ出しなどが生じず、縫い止め品のように穴バリ不良、糸切れなどができない。 The string fastener 1 is excellent in decorativeness because the main body 20 is formed by cutting to have a smooth appearance without distortion. The string fastener 1 is not fixed to the string portion S by crimping the entire main body portion 20, but only the end portion is bent, so that the fixed portion is difficult to see from the outside. Since the string fastener 1 does not crimp the entire main body 20, the joint does not appear on the appearance, and the bottom 20b, which is the tip, can be formed flat, so that the string fastener 1 is excellent in decorativeness. The string fastener 1 does not peel off or stick out due to poor adhesion, and unlike a sewn-in product, it does not have poor hole burrs or thread breakage.

〔実施の形態１の紐留具１の製造方法〕
次に紐留具１の製造方法について、図３に基づいて説明する。紐留具１は、仮留工程（Ｓ１）、配置工程（Ｓ２）及び押圧工程（Ｓ３）を経て製造される。図３は、紐留具１を製造する工程を示す図である。なお、図３（ｃ）及び図３（ｄ）は、本体部２０の内部の状態を示すため、本体部２０を切断した状態を示している。まず、仮留工程（Ｓ１）について説明する。図３（ａ）に示すように、紐部Ｓと仮留フィルム１５を用意し、仮留フィルム１５を紐部Ｓの端部に強く巻き付ける。紐部Ｓは、仮留フィルム１５が強く巻き付けられるため、その部分の外径が小さくなる。 [Manufacturing method of the string fastener 1 of the first embodiment]
Next, a method of manufacturing the string fastener 1 will be described with reference to FIG. The string fastener 1 is manufactured through a temporary fastening step (S1), an arranging step (S2), and a pressing step (S3). FIG. 3 is a diagram showing a process of manufacturing the string fastener 1. Note that FIGS. 3 (c) and 3 (d) show a state in which the main body 20 is cut in order to show the internal state of the main body 20. First, the temporary fixing step (S1) will be described. As shown in FIG. 3A, the string portion S and the temporary fixing film 15 are prepared, and the temporary fixing film 15 is tightly wound around the end portion of the string portion S. Since the temporary fixing film 15 is strongly wound around the string portion S, the outer diameter of that portion becomes smaller.

図３（ｂ）に示すように、紐部Ｓに仮留フィルム１５巻きつけた状態で熱をかけて収縮させると、紐部Ｓの端部に仮留部１０が形成される。次に、配置工程（Ｓ２）について説明する。図３（ｃ）に示すように、仮留部１０の全体を覆うように、縮径部３０が形成されていない本体部２０を被せて配置する。次に、押圧工程（Ｓ３）について説明する。仮留部１０に本体部２０を被せた状態で、本体部２０の開口部２０ｈに対して所定の力を加えて縮径部３０を形成する。縮径部３０は、開口部２０ｈに対して外側から押圧器具を当てて、本体部２０を押圧して塑性変形させて、内側に折り曲げて形成される。 As shown in FIG. 3B, when the temporary fixing film 15 is wound around the string portion S and contracted by applying heat, the temporary fixing portion 10 is formed at the end of the string portion S. Next, the arrangement step (S2) will be described. As shown in FIG. 3C, the main body portion 20 in which the diameter-reduced portion 30 is not formed is covered and arranged so as to cover the entire temporary fixing portion 10. Next, the pressing step (S3) will be described. With the temporary fastening portion 10 covered with the main body portion 20, a predetermined force is applied to the opening portion 20h of the main body portion 20 to form the reduced diameter portion 30. The reduced diameter portion 30 is formed by applying a pressing device to the opening 20h from the outside, pressing the main body portion 20 to plastically deform it, and bending it inward.

本体部２０を押圧器具で押圧しているとき、本体部２０を回転させているため、縮径部３０は、他端側から一端側にかけて徐々に径が小さくなるようにテーパ状に形成される。折り曲げられて形成された縮径部３０の内径は紐部Ｓの外径より小さく形成されているため、縮径部３０は紐部Ｓに食い込む。折り曲げられて形成された縮径部３０の内径は仮留部１０の外径より小さく形成されているため、収納部２３に収納された仮留部１０は本体部２０から抜けなくなる。 Since the main body 20 is rotated when the main body 20 is pressed by the pressing device, the reduced diameter portion 30 is formed in a tapered shape so that the diameter gradually decreases from the other end side to the one end side. .. Since the inner diameter of the reduced diameter portion 30 formed by bending is smaller than the outer diameter of the string portion S, the reduced diameter portion 30 bites into the string portion S. Since the inner diameter of the reduced diameter portion 30 formed by bending is smaller than the outer diameter of the temporary fastening portion 10, the temporary fastening portion 10 housed in the storage portion 23 cannot be removed from the main body portion 20.

In this example, the decorative portion 140 is printed only on a part of the peripheral wall of the main body portion, but the peripheral wall of the main body portion 120 may be printed all around. Since the decorative portion 140 is printed on the main body portion 120 formed to have a smooth appearance without distortion by cutting, it is excellent in design and can widen the range of design selection. Since the main body 130 of the string fastener 101 is rotatable, the decorative portion 140 can be positioned at any position.

〔実施の形態３〕
本発明の実施の形態３を図面に基づいて詳細に説明する。なお、この実施の形態３の紐留具２０１は、前述した実施の形態１の紐留具１とほぼ同様の構成である。このため、異なる構成である装飾部２４０の詳細な説明はするが、同様の構成である仮留部２１０、本体部２２０及び縮径部２３０については説明は省略する。 [Embodiment 3]
Embodiment 3 of the present invention will be described in detail with reference to the drawings. The string fastener 201 of the third embodiment has almost the same configuration as the string fastener 1 of the first embodiment described above. Therefore, although the decorative portion 240 having a different configuration will be described in detail, the description of the temporary fastening portion 210, the main body portion 220, and the diameter-reduced portion 230 having the same configuration will be omitted.

図５（ａ）は、本発明の実施の形態２の紐留具２０１を拡大した状態を示す拡大図であり、図５（ｂ）は、紐留具２０１を切断した状態を示す断面図である。図５（ａ）に示すように、本体部２２０には、本体部２２０の装飾性を向上させるための装飾部２４０が取り付けられている。本例において、装飾部２４０は、宝石としてラインストーンが使用されている。装飾部２４０は、台座部２５０を介して本体部２２０の周壁に取り付けられている。 FIG. 5A is an enlarged view showing an enlarged state of the string fastener 201 according to the second embodiment of the present invention, and FIG. 5B is a cross-sectional view showing a state in which the string fastener 201 is cut. be. As shown in FIG. 5A, a decorative portion 240 for improving the decorativeness of the main body 220 is attached to the main body 220. In this example, the decorative portion 240 uses rhinestones as jewels. The decorative portion 240 is attached to the peripheral wall of the main body portion 220 via the pedestal portion 250.

台座部２５０は、本体部２２０に接着剤等で取り付けられており、装飾部２４０は、台座部２５０に接着剤等で取り付けられている。装飾部２４０は、本体部２２０の先端に形成された切削部２６０に取り付けられている。切削部２６０は、本体部２２０の先端に切削加工により形成されている。装飾部２４０は、飾りとして使用できるものであれば、合成樹脂、金属、宝石、ガラス、貝、水晶、木及び鉱物から選択される１種以上の部材で良い。 The pedestal portion 250 is attached to the main body portion 220 with an adhesive or the like, and the decorative portion 240 is attached to the pedestal portion 250 with an adhesive or the like. The decorative portion 240 is attached to a cutting portion 260 formed at the tip of the main body portion 220. The cutting portion 260 is formed at the tip of the main body portion 220 by cutting. The decorative portion 240 may be one or more members selected from synthetic resin, metal, gemstone, glass, shellfish, crystal, wood and mineral as long as it can be used as a decoration.

本例では、装飾部２４０は、本体部の周壁に三個取り付けられているが、本体部２２０に一個だけ取り付けても良いし、本体部２２０の周壁を一周にわたり複数個取り付けられても良い。紐留具２０１は、装飾部２４０として宝石が取り付けられることで、さらに意匠性に優れるとともに、デザイン選択の幅が広くできる。また、本体部２２０は、その全体が押圧されることなく、つまり、かしめることなく製造されているため、ラインストーン等の比較的壊れやすい宝石を使用できる。紐留具２０１は、本体部２３０が回転自在であるため、装飾部２４０を好きな位置にすることができる。 In this example, three decorative portions 240 are attached to the peripheral wall of the main body portion, but only one may be attached to the main body portion 220, or a plurality of peripheral walls of the main body portion 220 may be attached over one circumference. By attaching a jewel as a decorative portion 240 to the string fastener 201, the design is further improved and the range of design selection can be widened. Further, since the main body 220 is manufactured without being pressed, that is, without caulking, a relatively fragile gem such as a rhinestone can be used. Since the main body 230 of the string fastener 201 is rotatable, the decorative portion 240 can be positioned at any position.

〔実施の形態４〕
本発明の実施の形態４を図面に基づいて詳細に説明する。なお、この実施の形態４の紐留具３０１は、前述した実施の形態１の紐留具１とほぼ同様の構成である。このため、異なる構成である仮留部３１０及び本体部３２０の詳細な説明はするが、同様の構成である縮径部３３０及び装飾部３４０については説明は省略する。 [Embodiment 4]
