Definitions

  • the present invention relates to a fastener for a slide fastener, in particular, a fastener for a lower end portion of the slide fastener.
  • a two-dimensional slide fastener usually exists in a plane composed of a first length direction, which is the first movement direction of the slider when it opens and closes, and a second length direction perpendicular to the first length direction.
  • first length direction there is a pair of tapes laid flat, each tape having an inner edge that is the edge of each tape closest to the corresponding edge of the other tape.
  • element or tooth
  • the elements of the first tape are releasably pushed into the space between two cooperating successive elements of the second tape.
  • Tapes with elements attached in this way are known as stringers. When two stringers are joined together, they are known as chains. Get a piece of chain and place it on the slider, upper stop and lower stop (the stop will drop off the chain either by the upper stop or by the lower stop) When it is installed, a slide fastener is created, thereby completing the slide fastener.
  • Elements (or teeth) and sliders and fasteners add a third height dimension to the discussion.
  • the third height dimension is a direction perpendicular to both the first length direction and the second length direction.
  • the present invention does not specifically consider the jacket and related problems, but the following discussion refers to the jacket.
  • the slide fastener on the front of the jacket needs to be completely separable into two different stringers so that the wearer's body can move through the gap between the stringers when opened.
  • the slider has a lock mechanism that is permanently in place, the slider will fall off the attached stringer. For this reason, a blocking mechanism is required.
  • the blocking mechanism can be either a plastic or metal fused tooth, or a separate deposit, as long as it protrudes into the normal path of the slider and prevents the slider from moving beyond the end of the dentition. Good. This type of mechanism is required above and below the slide fastener.
  • the slide fastener does not have any blocking mechanism, there is nothing to prevent the tooth from separating, and they must be prevented when the slide fastener is in the closed position.
  • the first option to prevent segregation of the tooth is to sew a slide fastener stringer into the jacket in a manner that prevents the slider from falling off using the jacket material. This option is selected with a pocket slide fastener where the pocket mouth gap terminates.
  • the second most common option is to use an opener, a so-called box-throwbar arrangement, whereby the first of the two stringers of the jacket extends along the stringer in a direction away from the service teeth. It has a pin-shaped protrusion (butterfly stick). This protrusion is designed to advance on one side of the Y-shaped channel provided by the slider.
  • the second stringer has a similar pin shape that begins to extend along the stringer, but is attached to the second stringer and is provided with a receiver (“box”) for the first stringer's butterfly bar. The butterfly bar is inserted into it, thereby holding the engaged chain in place as the slider passes along it.
  • This type of slide fastener is called an “open fastener” (open product) because its lower end can be opened.
  • closed fasteners The opposite of open fasteners is closed fasteners (stopped products). Close fasteners have ends that do not open at both ends of the tooth. In a slide fastener with an opener attached, the box effectively holds the butterfly pin in place and, in cooperation with such a slider, the two stringers are brought into close proximity before closing. However, the closed fastener is attached with the closed end straddling both stringers. Thus, closed-end slide fasteners are not suitable for jackets because the wearer cannot pass through this type of stop.
  • the slide fastener of the present disclosure is related to a fastener in the form of a closed fastener, particularly a lower fastener. Its application is mainly in the field of bags and trunks, but it may be used in other areas such as pockets.
  • the present invention originates from the examination of the process of making one bag / trunk such as a handbag.
  • the handbag may be sewn first, followed by a slide fastener attached to the mouth of the handbag.
  • the two pieces can then be brought together, to which are attached one or more sliders, and finally a stop can be attached beyond the last element on each side of the stringer element row.
  • the stop may be of many types well known to those skilled in the art, and in particular may be an H-shaped contoured closed end stop.
  • the bottom stop of the H-shaped profile is so called because it looks like H on its side.
  • This type of stop may be used to grip a cord of tape that extends beyond the service teeth within each mouth of H.
  • cords can be incorporated along opposite edges of two tapes of a slide fastener. Coiled teeth can continue to be sewn into the cord, whereas when using metal or plastic teeth, they are each crimped to the cord or injected around the cord.
  • U-shaped contour fasteners may be used by including both cords in their mouths and then crimping them.
  • the cord is used as a fixing point for the fastener.
  • This procedure can point out many problems. 1) Appropriate pressure must be applied to the fastener to ensure crimping. 2) As is usually the case, when the crimping operation is performed manually, the accuracy of the stopper arrangement cannot be guaranteed. 3) Manual labor struggles with possible repetitive stress problems. 4) Crimping pressure can lead to variations in a series of final products. 5) The crimping device is not easy to operate. Pliers are commonly used.

Description

スライドファスナー用止具及びスライドファスナーSlide fastener fastener and slide fastener
　本発明は、スライドファスナー用止具、特に、スライドファスナーの下端部用止具に関する。 The present invention relates to a fastener for a slide fastener, in particular, a fastener for a lower end portion of the slide fastener.
　スライドファスナーは、通常、それが開閉する際のスライダーの第１移動方向である第１長さ方向及びその第１長さ方向に対して垂直な第２長さ方向からなる平面に存在する二次元品目と考えられる。第１長さ方向において、平らに置かれた一対のテープが存在し、それぞれのテープは、他方のテープの相当縁部に最も近い各テープの縁部である内縁部を有する。それぞれのテープの内縁部には、それぞれのエレメントに対するスライダーの動作によって内縁部が互いの方へ引き寄せられる時にこれらのエレメントを互いに噛合させることを確かにする様態で、エレメント（又は務歯）が取り付けられている。即ち、第１テープのエレメントは、第２テープの２つの協働する連続したエレメント間のスペースに解放可能に押し込まれる。エレメントがこのように取り付けられたテープは、ストリンガーとして知られる。２つのストリンガーが一体に結合された時、それらはチェーンとして知られる。一片のチェーンを得て、そのチェーンにスライダー、上止具及び下止具（止具はスライダーが（上止具によって）上部又は（下止具によって）下部のどちらかでチェーンから脱落するのを阻止する設計になっている）を取り付けた時に、スライドファスナーが創成され、これによりスライドファスナーを完成する。エレメント（又は務歯）並びにスライダー及び止具は、ディスカッションに第３の高さ次元を追加する。第３の高さ次元とは、第１長さ方向及び第２長さ方向の両方に対して垂直に交差する方向である。 A two-dimensional slide fastener usually exists in a plane composed of a first length direction, which is the first movement direction of the slider when it opens and closes, and a second length direction perpendicular to the first length direction. Considered an item. In the first length direction, there is a pair of tapes laid flat, each tape having an inner edge that is the edge of each tape closest to the corresponding edge of the other tape. At the inner edge of each tape is attached an element (or tooth) in a manner that ensures that the elements engage each other when the inner edge is pulled towards each other by the movement of the slider relative to the respective element. It has been. That is, the elements of the first tape are releasably pushed into the space between two cooperating successive elements of the second tape. Tapes with elements attached in this way are known as stringers. When two stringers are joined together, they are known as chains. Get a piece of chain and place it on the slider, upper stop and lower stop (the stop will drop off the chain either by the upper stop or by the lower stop) When it is installed, a slide fastener is created, thereby completing the slide fastener. Elements (or teeth) and sliders and fasteners add a third height dimension to the discussion. The third height dimension is a direction perpendicular to both the first length direction and the second length direction.
　従来技術をより良好に理解するために、本発明はジャケット及びそれに関連する問題について特定的には考えていないが、以下の検討はジャケットに言及する。ジャケットの前面のスライドファスナーは、開く時に着用者の身体がストリンガー間の間隙を移動できるように２つの異なるストリンガーに完全に分離できる必要がある。しかし、永久的に適位置にあるロック機構をスライダーが持たない限り、スライダーは取り付けられたストリンガーから脱落する。この理由で、阻止機構が必要とされる。 In order to better understand the prior art, the present invention does not specifically consider the jacket and related problems, but the following discussion refers to the jacket. The slide fastener on the front of the jacket needs to be completely separable into two different stringers so that the wearer's body can move through the gap between the stringers when opened. However, unless the slider has a lock mechanism that is permanently in place, the slider will fall off the attached stringer. For this reason, a blocking mechanism is required.
　阻止機構は、スライダーの通常経路内に突出してスライダーが務歯列の端部を越えて移動するのを防止する限り、プラスチック又は金属どちらかの溶融務歯、又は別個の付着物であってもよい。この形式の機構はスライドファスナーの上下で必要とされる。 The blocking mechanism can be either a plastic or metal fused tooth, or a separate deposit, as long as it protrudes into the normal path of the slider and prevents the slider from moving beyond the end of the dentition. Good. This type of mechanism is required above and below the slide fastener.
　さらに、スライドファスナーがいずれの阻止機構も持たなければ、務歯が分離するのを防ぐものは何もなく、スライドファスナーが閉鎖位置にある時、それらは妨げられなければならない。 Furthermore, if the slide fastener does not have any blocking mechanism, there is nothing to prevent the tooth from separating, and they must be prevented when the slide fastener is in the closed position.
　務歯が分離するのを防ぐ第１選択肢は、ジャケットの材料を使用してスライダーが脱落するのを防ぐ様態で、スライドファスナーストリンガーをジャケットに縫い込むことである。この選択肢は、ポケットの口の間隙が終端するポケットのスライドファスナーで選択される。 The first option to prevent segregation of the tooth is to sew a slide fastener stringer into the jacket in a manner that prevents the slider from falling off using the jacket material. This option is selected with a pocket slide fastener where the pocket mouth gap terminates.
　第２の最も一般的な選択肢は、開き具、いわゆる箱・蝶棒構成を使用することであり、これによってジャケットの２つのストリンガーの第１のものは務歯から離れる方向にストリンガーに沿って延びるピン形状の突出部（蝶棒）を有する。この突出部はスライダーによって設けられたＹ字形チャネルの片側を進んで行く設計になっている。他方、第２ストリンガーには、ストリンガーに沿って延び始める類似のピン形状があるが、この第２ストリンガーに取り付けられ、第１ストリンガーの蝶棒のための受け（「箱」）が設けられており、その中に蝶棒が挿入され、それによりスライダーがそれに沿って通ると、係合したチェーンを適位置に保持する。この形式のスライドファスナーは、下端部を開放できるので、「オープンファスナー」（開き製品）と呼ばれる。 The second most common option is to use an opener, a so-called box-throwbar arrangement, whereby the first of the two stringers of the jacket extends along the stringer in a direction away from the service teeth. It has a pin-shaped protrusion (butterfly stick). This protrusion is designed to advance on one side of the Y-shaped channel provided by the slider. On the other hand, the second stringer has a similar pin shape that begins to extend along the stringer, but is attached to the second stringer and is provided with a receiver ("box") for the first stringer's butterfly bar. The butterfly bar is inserted into it, thereby holding the engaged chain in place as the slider passes along it. This type of slide fastener is called an “open fastener” (open product) because its lower end can be opened.
　オープンファスナーの反対物はクローズファスナー（止め製品）である。クローズファスナーは開放しない端部を務歯の両端に有する。開き具が取り付けられたスライドファスナーにおいて、箱は蝶棒を適位置に効果的に保持し、そのようなスライダーとの協働により、２つのストリンガーは閉鎖前に近接させられる。しかし、クローズファスナーは閉端止具が両方のストリンガーにまたがって取り付けられる。従って、閉端スライドファスナーは、着用者がこの形式の止具を通り抜けることができないので、ジャケットには不適切である。 The opposite of open fasteners is closed fasteners (stopped products). Close fasteners have ends that do not open at both ends of the tooth. In a slide fastener with an opener attached, the box effectively holds the butterfly pin in place and, in cooperation with such a slider, the two stringers are brought into close proximity before closing. However, the closed fastener is attached with the closed end straddling both stringers. Thus, closed-end slide fasteners are not suitable for jackets because the wearer cannot pass through this type of stop.
　本開示のスライドファスナーは、クローズファスナー形式の止具、特に下止具に関連している。その用途は主に鞄・トランク類の分野にあるが、例えばポケットといった他の領域に使用してもよい。 The slide fastener of the present disclosure is related to a fastener in the form of a closed fastener, particularly a lower fastener. Its application is mainly in the field of bags and trunks, but it may be used in other areas such as pockets.
　本発明は、ハンドバッグといった１個の鞄・トランク類を作るプロセスの検討に起因する。ハンドバッグは最初に縫製され、引き続きスライドファスナーがハンドバッグの口に取り付けられるとしてよい。これは多くの難題をもたらす。この理由で、代替方法が用いられる。詳しくは、多くの方法は、ハンドバッグの口を形成するべく意図された一片の材料側に１つのストリンガーを取り付け、口の反対側を形成するのを助ける対応する材料部片に他方のストリンガーを取り付けることを含む。２つの部片はその後一緒に合わせられ、それらに単数又は複数のスライダーが取り付けられ、最後に止具がストリンガーのエレメント列の各側の最終エレメントを越えて取り付けられ得る。この構成において、止具は当業者で周知の多くの形式のものとしてよく、特にＨ字形輪郭の閉端下止具としてよい。Ｈ字形輪郭の下止具はその側面でＨのように見えるのでそう呼ばれる。この種類の止具は、Ｈのそれぞれの口の内部において務歯を越えて延びるテープのコードを把持するのに使用してもよい。周知の通り、コードはスライドファスナーの２つのテープの対向する縁部に沿って組み込まれ得る。コイル務歯は引き続きコードに縫製され得るのに対し、金属又はプラスチック務歯を使用する場合、それらはそれぞれ、コードに圧着されるか、又はコードのまわりに射出される。代替として、Ｕ字形輪郭の止具は、両方のコードをその口に包含させてから圧着することによって使用してもよい。 The present invention originates from the examination of the process of making one bag / trunk such as a handbag. The handbag may be sewn first, followed by a slide fastener attached to the mouth of the handbag. This poses many challenges. For this reason, alternative methods are used. Specifically, many methods attach one stringer to a piece of material side intended to form the mouth of a handbag and attach the other stringer to a corresponding piece of material that helps form the opposite side of the mouth. Including that. The two pieces can then be brought together, to which are attached one or more sliders, and finally a stop can be attached beyond the last element on each side of the stringer element row. In this configuration, the stop may be of many types well known to those skilled in the art, and in particular may be an H-shaped contoured closed end stop. The bottom stop of the H-shaped profile is so called because it looks like H on its side. This type of stop may be used to grip a cord of tape that extends beyond the service teeth within each mouth of H. As is well known, cords can be incorporated along opposite edges of two tapes of a slide fastener. Coiled teeth can continue to be sewn into the cord, whereas when using metal or plastic teeth, they are each crimped to the cord or injected around the cord. Alternatively, U-shaped contour fasteners may be used by including both cords in their mouths and then crimping them.
　従来技術において、コードは止具のための固定点として使用される。この手順では多くの問題が指摘できる。
１）圧着を確実に行うために止具に相当の圧力を加えなければならない。
２）通常そうであるように、圧着作業を手動で行う場合、止具の配置の精度が保証できない。
３）手作業は起こり得る反復的ストレス問題に苦慮する。
４）圧着圧力が一連の最終製品のばらつきにつながり得る。
５）圧着装置は操作が容易でない。プライヤーが一般に使用される。 In the prior art, the cord is used as a fixing point for the fastener. This procedure can point out many problems.
1) Appropriate pressure must be applied to the fastener to ensure crimping.
2) As is usually the case, when the crimping operation is performed manually, the accuracy of the stopper arrangement cannot be guaranteed.
3) Manual labor struggles with possible repetitive stress problems.
4) Crimping pressure can lead to variations in a series of final products.
5) The crimping device is not easy to operate. Pliers are commonly used.

　本発明に係る止具の一実施形態について図面を参照して説明する。図面に関する以下の説明において、同一又は類似の部分には同一又は類似の参照番号が割り当てられている。 An embodiment of a fastener according to the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are assigned the same or similar reference numerals.
　図１は、本発明に従った下止具を含むスライドファスナーの第１実施形態を示す例示的な平面図である。スライドファスナー１は、左右のファスナーテープ４，５、及び左右のファスナーテープ４，５の対向する縁部に沿って２列に配された複数のファスナーエレメント６，７を含む左右のファスナーストリンガー２，３と、２列のファスナーエレメント６，７を互いに係合し分離するためのスライダー１０と、を備える。ファスナーテープ４，５の対向する縁部に形成されるコード８，９は、図９に示されている。 FIG. 1 is an exemplary plan view showing a first embodiment of a slide fastener including a lower stop according to the present invention. The slide fastener 1 includes left and right fastener stringers 2 including left and right fastener tapes 4 and 5 and a plurality of fastener elements 6 and 7 arranged in two rows along opposing edges of the left and right fastener tapes 4 and 5. 3 and a slider 10 for engaging and separating the two rows of fastener elements 6 and 7 from each other. The cords 8 and 9 formed on the opposite edges of the fastener tapes 4 and 5 are shown in FIG.
　以下の説明において、別段に述べていない限り、用語「縦」又は「長さ方向」又は「上下」は、スライドファスナーに沿ったスライダーの移動方向を示す。詳しくは、スライダー１０がファスナーエレメント６，７の列を係合するためにファスナーエレメントの列に関して相対的に移動する方向は「上方」と定義され、スライダーが移動してファスナーエレメント６，７の列を分離する方向は「下方」と定義される。また、ファスナーテープの表面と裏面を横切り、縦方向に対して直交する方向は「横」方向又は「幅」方向として定義される。 In the following description, unless otherwise stated, the terms “vertical” or “length direction” or “up and down” indicate the moving direction of the slider along the slide fastener. Specifically, the direction in which the slider 10 moves relative to the fastener element rows to engage the rows of fastener elements 6 and 7 is defined as “upward”, and the slider moves to move the fastener elements 6 and 7 rows. The direction of separating is defined as “downward”. Further, a direction that crosses the front and back surfaces of the fastener tape and is orthogonal to the longitudinal direction is defined as a “lateral” direction or a “width” direction.
　ファスナーエレメント６，７の列の下端部には、下止具（以下、単に「止具」と言うこともある）２０が左右のファスナーテープ４，５にわたって固定されている。図示していないが、下止具２０に類似の上止具（又はストッパー）が、ファスナーエレメント６，７の列の上端部（不図示）に固定され得る。 A lower stopper (hereinafter sometimes simply referred to as “stopper”) 20 is fixed to the lower ends of the fastener elements 6 and 7 across the left and right fastener tapes 4 and 5. Although not shown, an upper stopper (or stopper) similar to the lower stopper 20 may be fixed to the upper end (not shown) of the row of the fastener elements 6 and 7.
　以下の説明では、下止具に言及する。同じ原理は上止具としても当てはまるが、その品を上止具として使用する場合、本書で後述する機能のうちの１つが必要ないことを認識するはずである。 In the following explanation, reference is made to the bottom stop. The same principle applies as a top stop, but it should be recognized that one of the functions described later in this document is not required when the item is used as a top stop.
　図１において、スライダー１０よりも下に位置する左右のファスナーエレメント６，７は互いに係合しており、スライダー１０よりも上に位置する左右のファスナーエレメント６，７は係合していない（つまり分離している）。 In FIG. 1, the left and right fastener elements 6, 7 positioned below the slider 10 are engaged with each other, and the left and right fastener elements 6, 7 positioned above the slider 10 are not engaged (that is, Separated).
　ファスナーエレメント６，７は、両側に同一形状でファスナーテープの表面と裏面に熱可塑性樹脂などの合成樹脂を射出成形することによって形成可能である。図示していないが、ファスナーテープには、その対向する縁部に沿って貫通孔を形成し、ファスナーエレメントを製造する際に溶融樹脂がその穴を流れるようにできる。代替として、ファスナーエレメントを金属で作り、各テープの縁部のコードに圧着してもよい。ファスナーエレメント及びスライダーは従来設計のものであってよく、この文脈において詳細な説明は不要であると考えられる。ここでは、（図２の断面図で図式的に示した）スライダーが、上翼部１３、下翼部１４、及び両翼部を連結する連結柱（又は「ダイヤモンド」ともいう）１５を有しており、これによってスライダーは既知の様態で、スライダーがエレメントの列に沿って移動する際にファスナーエレメントを噛合及び連結させ、又は分離させるためにその内部にＹ字形経路を設けている。Ｙ字形経路は、図１７に示すように、互いに連結されたファスナーエレメント６，７が通る開口部である後口１６と、分離されたファスナーエレメント６，７が通る一対の開口部である一対の肩口１７と、一対の肩口１７側から連続して形成され、連結柱１５によって分岐して形成される一対の肩口側通路１８と、一対の肩口側通路１８を合流させて後口１６まで形成される後口側通路１９と、を備える。 Fastener elements 6 and 7 can be formed by injection molding a synthetic resin such as a thermoplastic resin on the front and back surfaces of the fastener tape with the same shape on both sides. Although not shown, through-holes are formed in the fastener tape along the opposing edges, so that the molten resin can flow through the holes when the fastener element is manufactured. Alternatively, the fastener element may be made of metal and crimped to the cord at the edge of each tape. The fastener element and slider may be of conventional design and detailed description is considered unnecessary in this context. Here, the slider (shown schematically in the cross-sectional view of FIG. 2) has an upper wing part 13, a lower wing part 14, and a connecting column (also referred to as “diamond”) 15 that connects both wing parts. Thus, in a known manner, the slider is provided with a Y-shaped path therein to engage and connect or separate the fastener elements as the slider moves along the row of elements. As shown in FIG. 17, the Y-shaped path is a pair of rear openings 16 through which the mutually connected fastener elements 6 and 7 pass, and a pair of openings through which the separated fastener elements 6 and 7 pass. The shoulder opening 17 is formed continuously from the side of the pair of shoulder openings 17, and is formed up to the rear opening 16 by joining the pair of shoulder opening passages 18 formed by branching the connecting pillar 15 and the pair of shoulder opening passages 18. And a rear opening side passage 19.
　縦方向及び横方向に対して直交する方向は、「垂直」方向又は「高さ」方向として定義する。 The direction perpendicular to the vertical and horizontal directions is defined as the “vertical” direction or the “height” direction.
　下止具２０は、本書に後述する様態で、スライドファスナーの一端部のファスナーエレメントの１つ以上わたってスライドファスナーのテープ４，５に止着するクリップの働きをする。また、別の様態では、下止具２０は、外部から力を加えることによって、下止具２０をスライドファスナーの一端部のファスナーエレメントの１つ以上わたってスライドファスナーのテープ４，５に加締め固定をする働きをする。また、下止具２０は、その両方の働きをするものである。 The lower stopper 20 functions as a clip that is fastened to the tape 4 and 5 of the slide fastener over one or more fastener elements at one end of the slide fastener in a manner described later in this document. Further, in another aspect, the lower stopper 20 is caulked to the slide fastener tapes 4 and 5 across one or more fastener elements at one end of the slide fastener by applying a force from the outside.

A pair of left and right first vertical flanges 24 project from the upper wing portion 21 toward the lower wing portion 22 on the lateral side (vertical edge portion) extending in the vertical direction of the upper wing portion 21. A pair of left and right second vertical flanges 24 are formed so as to protrude from the lower wing portion 22 toward the upper wing portion 21 on the lateral side (vertical edge portion) extending in the direction. The first and second longitudinal flanges 24 are parallel and form a pair of left and right slots 25 extending longitudinally on both lateral sides of the stop.

The inner channel 29 is configured to accommodate two cords 8, 9 and a combined fastener element 6, 7 of a certain length (see FIG. 5).
　それぞれのスロット２５の垂直高さは、ファスナーエレメント６，７の垂直寸法（又は垂直厚さ、つまり高さ）よりも小さい。 The vertical height of each slot 25 is smaller than the vertical dimension (or vertical thickness, that is, height) of the fastener elements 6 and 7.

In one embodiment, the height of the slot 25 may be 70-85% of the cord thickness. According to another embodiment, the height of the slot 25 may be smaller than half the distance between the inner surfaces 31 and 32 of the wings 21 and 22 (that is, the height of the connecting column 23).
　図面に示した例示的実施形態とは異なって、第１及び第２縦フランジ２４のそれぞれの高さは同一でなくてもよい。 Unlike the exemplary embodiment shown in the drawings, the heights of the first and second vertical flanges 24 may not be the same.
　図面に示した例示的実施形態において、それぞれの翼部２１，２２は、上翼部２１又は下翼部２２の内面から延びる一対のフランジ２４を設けている。 In the exemplary embodiment shown in the drawings, each wing 21, 22 is provided with a pair of flanges 24 extending from the inner surface of the upper wing 21 or the lower wing 22.
　更なる実施形態（不図示）によれば、２つの翼部２１，２２のうちの一方だけが一対のフランジ２４を設けてもよく、この場合、スロット２５の高さは、エレメントの高さよりも小さい。 According to a further embodiment (not shown), only one of the two wings 21, 22 may be provided with a pair of flanges 24, in which case the height of the slot 25 is higher than the height of the element. small.
　内側チャネル２９は、前端部（又は上端部）２６から後端部（又は下端部）２７まで、止具の内部で長さ方向に延びるとしてよい。 The inner channel 29 may extend from the front end (or upper end) 26 to the rear end (or lower end) 27 in the length direction inside the stopper.
　例示実施形態において、内側チャネル２９は下止具２０を貫いて縦方向に延びている。前端部２６は開放しているが、後端部２７は開放していても閉鎖していてもよい。例示実施形態において、内側チャネル２９の後端部２７は開放している。 In the illustrated embodiment, the inner channel 29 extends longitudinally through the lower stop 20. Although the front end portion 26 is open, the rear end portion 27 may be open or closed. In the illustrated embodiment, the rear end 27 of the inner channel 29 is open.
　他の実施形態（不図示）によれば、連結柱２３を横方向に拡張し、止具の後端部で壁を形成し、これによって内側チャネル２９の後端部２７が閉鎖されることもある。 According to another embodiment (not shown), the connecting post 23 can be expanded laterally to form a wall at the rear end of the stop, thereby closing the rear end 27 of the inner channel 29. is there.
　例示実施形態のように、下止具２０は、概ね矩形の中実本体を成すとしてよい。止具の外形及び全体の大きさは異なり得る。要求される強度特性に応じて、止具は、金属又は他の硬質材料、又は比較的硬質なプラスチック材料の一体品で作られ得る。好ましくは、同じスライドファスナーの場合、止具及びファスナーエレメントは同じ種類の材料又は類似の強さを有する材料で作られる。プラスチック製止具は、損傷を与えることなくプラスチック製ファスナーエレメントと良好に相互作用する。同様に、金属製止具は金属製エレメントを有するスライドファスナーで好ましい。 As in the illustrated embodiment, the bottom stop 20 may be a generally rectangular solid body. The external shape and overall size of the fastener can vary. Depending on the required strength characteristics, the fastener can be made of metal or other hard material, or a single piece of relatively hard plastic material. Preferably, in the case of the same slide fastener, the fastener and fastener element are made of the same type of material or materials having similar strength. Plastic fasteners interact well with plastic fastener elements without damage. Similarly, the metal fastener is preferably a slide fastener having a metal element.
　実施形態によれば、阻止機能を更に向上させるために、同じ翼部の２つのフランジ２４の間の横幅は、係合したファスナーエレメント６，７の幅よりもわずかに広くして、フランジ２４と下止具２０内の結合したファスナーエレメントとの間に所定の限られた横方向の遊びを許すようにしてよい。 According to the embodiment, in order to further improve the blocking function, the lateral width between the two flanges 24 of the same wing is slightly wider than the width of the engaged fastener elements 6, 7, A predetermined limited lateral play may be allowed between the joined fastener elements in the lower stop 20.
　内部高さ、即ち２つの翼部２１，２２の互いに対面する内面３１，３２間の垂直距離は、ファスナーエレメント６，７の垂直厚さ又は高さよりもわずかに大きくして、内面３１，３２と下止具２０内の結合したファスナーエレメントとの間に所定の限られた垂直方向の遊びを許すようにしてよい。 The internal height, i.e. the vertical distance between the inner surfaces 31, 32 facing each other of the two wings 21, 22, is slightly larger than the vertical thickness or height of the fastener elements 6, 7, so that the inner surfaces 31, 32 and A predetermined limited vertical play may be allowed between the fastener elements in the bottom stop 20.
　下止具２０は、互いに対面する内面３１，３２の少なくとも一方から他方の内面３２，３１の方向に突出する少なくとも１つの内側突出部３３を設けている。少なくとも１つの内側突出部３３は、内側チャネル２９の内部において同一テープ４（又は５）に固定された２つの連続するファスナーエレメント６（又は７）の間にあるスペースの内部に突出する構成になっている。 The lower stopper 20 is provided with at least one inner projecting portion 33 that projects in the direction of the other inner surface 32, 31 from at least one of the inner surfaces 31, 32 facing each other. At least one inner protrusion 33 protrudes into the space between two successive fastener elements 6 (or 7) fixed to the same tape 4 (or 5) inside the inner channel 29. ing.
　好ましくは、内側突出部３３は、左右のストリンガー２，３の少なくとも一方、又は、両方のストリンガー２，３のエレメント間で２つの翼部２１，２２の両方の内面３１，３２から突出するように設けられている。 Preferably, the inner protrusion 33 protrudes from the inner surfaces 31 and 32 of the two wings 21 and 22 between at least one of the left and right stringers 2 and 3 or between the elements of both the stringers 2 and 3. Is provided.
　内側突出部３３は直線状であり、縦フランジ２４に対して直交する横方向に延びていてもよい。言い換えれば、エレメント間に確実に係合されるように、エレメントの側面の直線形状に合わせて内側突出部３３は形成されている。 The inner projecting portion 33 is linear and may extend in a lateral direction perpendicular to the vertical flange 24. In other words, the inner protrusion 33 is formed in accordance with the linear shape of the side surface of the element so as to be reliably engaged between the elements.
　好ましくは、それぞれの内側突出部３３は、下止具２０の幅方向における中心縦中間線を越えて、又はそれを横切って延びていない。この配列によって、各内側突出部３３は、同一テープの２つのファスナーエレメントの間に突出するが、他方のテープのファスナーエレメントには干渉しない。また、それぞれの内側突出部３３は、連結柱２３の側縁よりも外側に形成されている。 Preferably, each inner protrusion 33 does not extend beyond or across the central longitudinal middle line in the width direction of the lower stop 20. With this arrangement, each inner protrusion 33 protrudes between two fastener elements of the same tape, but does not interfere with the fastener element of the other tape. Each inner protrusion 33 is formed outside the side edge of the connecting column 23.
　好ましくは、内側突出部３３は、フランジ２４に隣接している。すなわち、内側突出部３３は、フランジ２４の側面に連結されており、例示実施形態のように、内側突出部３３は、フランジ２４から横方向に延びていてもよい。 Preferably, the inner protrusion 33 is adjacent to the flange 24. That is, the inner protrusion 33 is connected to the side surface of the flange 24, and the inner protrusion 33 may extend laterally from the flange 24 as in the exemplary embodiment.
　内側突出部３３は、エレメント（務歯）の幅から、協働するエレメントと係合するために使用されるエレメントの一部である頭部の幅を引いたものよりも小さい横幅を有するとしてよい。言い換えると、各内側突出部３３の横幅は、エレメントの係合に干渉しないように設定される。 The inner protrusion 33 may have a lateral width that is less than the width of the element (service tooth) minus the width of the head that is part of the element used to engage the cooperating element. . In other words, the lateral width of each inner protrusion 33 is set so as not to interfere with the engagement of the elements.
　それぞれの内側突出部３３の横幅は、好ましくは、ファスナーエレメントの尾部／脚部の横幅よりも小さい。周知の通り、エレメントの脚部は、コードを包囲する部分を有し、それによりエレメントをテープに固定する。 The lateral width of each inner protrusion 33 is preferably smaller than the lateral width of the tail / leg portion of the fastener element. As is well known, the leg of the element has a portion that surrounds the cord, thereby securing the element to the tape.
　さらに、内側突出部３３がフランジ２４から延びておらず、フランジ２４から横方向に離隔している場合、内側突出部３３とフランジ２４との間の距離及び内側突出部３３の横幅は、１つのファスナーエレメントの幅から頭部又は好ましくは脚部の幅を引いたものを超えてはならない。 Further, when the inner protrusion 33 does not extend from the flange 24 and is spaced laterally from the flange 24, the distance between the inner protrusion 33 and the flange 24 and the lateral width of the inner protrusion 33 are one. It must not exceed the width of the fastener element minus the width of the head or preferably the leg.
　内側突出部が突出するフランジの内面から離れる方向に延びる垂直距離という意味における内側突出部３３の高さは、ファスナーエレメント６，７の高さの半分よりも小さくてもよく、また、フランジの最長の垂直寸法又は最長の高さの半分よりも小さくてもよい。 The height of the inner protrusion 33 in the sense of a vertical distance extending in a direction away from the inner surface of the flange from which the inner protrusion protrudes may be smaller than half of the height of the fastener elements 6, 7, and the longest of the flange May be less than half the vertical dimension or half of the longest height.
　好ましくは、内側突出部３３は、下止具２０の内面３１，３２の間の距離の１５％を超えない距離だけ、それぞれの内面３１，３２から突出する。 Preferably, the inner protrusion 33 protrudes from the inner surfaces 31 and 32 by a distance not exceeding 15% of the distance between the inner surfaces 31 and 32 of the lower stop 20.
　下止具２０は、単数又は複数のファスナーエレメントにわたりスライドファスナーの閉鎖方向に押されて、それにより内側突出部３３が意図したエレメント間に静止できるように意図されている。これを考慮して、内側突出部３３の連結柱２３から離れる側の面は、斜面３５に形成されていてもよい。言い換えれば、斜面３５は、前端部２６から後端部２７に向けて内側突出部３３の高さ寸法が徐々に厚くなるような上り傾斜面である。好ましくは、斜面３５は、内面３１（又は内面３２）に対して鋭角を成している。 The lower stop 20 is intended to be pushed in the closing direction of the slide fastener over one or a plurality of fastener elements so that the inner protrusion 33 can rest between the intended elements. In consideration of this, the surface on the side away from the connecting pillar 23 of the inner protrusion 33 may be formed on the slope 35. In other words, the inclined surface 35 is an upward inclined surface in which the height dimension of the inner projecting portion 33 gradually increases from the front end portion 26 toward the rear end portion 27. Preferably, the inclined surface 35 forms an acute angle with respect to the inner surface 31 (or the inner surface 32).
　内側突出部３３は、のこぎり歯形状の断面形状に形成され、面取りした又は丸みのある頂上又は峰３４を有していてもよい。 The inner protrusion 33 is formed in a sawtooth cross-sectional shape, and may have a chamfered or rounded top or peak 34.
　ファスナーエレメントに対する阻止動作を最適化するために、内側突出部３３は、長さ方向に対して直交して延びており、それぞれのファスナーエレメント６又は７の横面に少なくとも部分的に当接する横面３７を有していてもよい。 In order to optimize the blocking action on the fastener elements, the inner projections 33 extend perpendicular to the length direction and are at least partially in contact with the lateral surfaces of the respective fastener elements 6 or 7 37 may be included.
　図面に示した例示的実施形態のように、内側突出部３３は、斜面３５が連結柱２３から離れる方向に向いた台形形状の断面輪郭を有し得る。他の実施形態（不図示）では、内側突出部３３は、斜面３５が連結柱２３から離れる方向に向いた三角形状の断面輪郭を有し得る。更に異なる他の実施形態（不図示）では、内側突出部３３は、連結柱２３から離れる方向に向いた斜面３５に類似の第１斜面、及び第１斜面に平行で連結柱２３に向いた第２斜面による偏菱形状の断面輪郭を有し得る。 As in the exemplary embodiment shown in the drawings, the inner protrusion 33 may have a trapezoidal cross-sectional profile with the inclined surface 35 facing away from the connecting column 23. In another embodiment (not shown), the inner protrusion 33 may have a triangular cross-sectional profile with the inclined surface 35 facing away from the connecting column 23. In still another different embodiment (not shown), the inner protrusion 33 has a first slope similar to the slope 35 facing away from the connecting pillar 23 and a first slope parallel to the first slope and facing the connecting pillar 23. It may have a rhomboid cross-sectional profile with two bevels.
　２つのテープの協働するファスナーエレメントの千鳥状配列のために、同じ翼部から突出し、スライドファスナーの異なるテープに固定されたファスナーエレメントと協働するように意図された２つの内側突出部３３は、横方向に整列していないが、平行であり、横方向及び縦方向の両方で互いに離隔している。 Due to the staggered arrangement of the two tape cooperating fastener elements, the two inner projections 33 intended to cooperate with fastener elements protruding from the same wing and fixed to different tapes of the slide fastener are: , Not laterally aligned, but parallel and spaced apart from each other in both the lateral and longitudinal directions.
　同じ翼部２１、２２は、同一テープに固定された異なるファスナーエレメントと協働するように意図された２つ以上の内側突出部３３を設けており、その場合、それらの内側突出部は縦方向に互いに離隔している。また、上翼部２１の内側突出部３３の位置は、下翼部２２の内側突出部３３の縦方向及び横方向において同位置に形成されている。すなわち、対向する上翼部２１の内側突出部３３と下翼部２２の内側突出部３３は同じテープに取り付けられた隣り合うエレメントによって画成された隙間に突出する。 The same wings 21, 22 are provided with two or more inner projections 33 intended to cooperate with different fastener elements fixed to the same tape, in which case these inner projections are longitudinal. Are separated from each other. Further, the position of the inner protrusion 33 of the upper wing part 21 is formed at the same position in the vertical direction and the horizontal direction of the inner protrusion 33 of the lower wing part 22. That is, the inner projecting portion 33 of the upper wing portion 21 and the inner projecting portion 33 of the lower wing portion 22 that are opposed to each other project into a gap defined by adjacent elements attached to the same tape.
　下止具２０がファスナーエレメントに沿って押される際に、翼部に加えられる力が翼部をわずかに開くように促して、ファスナーエレメントが内側突出部３３を通り越して移動することが必要であってもよい。従って、連結柱２３の材料は、ある程度の弾性を有していた方が好ましい。また、前端部２６から連結柱２３までの距離が少なくともエレメントの３ピッチ分の間隔があることが好ましい。これにより、連結柱２３のある程度の弾性力を確保することができる。 When the lower stop 20 is pushed along the fastener element, the force applied to the wings prompts the wings to open slightly and the fastener elements need to move past the inner protrusions 33. May be. Therefore, it is preferable that the material of the connecting column 23 has a certain degree of elasticity. Moreover, it is preferable that the distance from the front-end part 26 to the connection pillar 23 has the space | interval for at least 3 pitches of an element. Thereby, a certain amount of elastic force of the connecting column 23 can be secured.
　連結柱２３の高さは、ファスナーエレメント６，７よりもわずかに高く（即ち垂直方向でより長く）、協働するスライダー１０の連結柱１５の高さと同じであってもよい。 The height of the connecting column 23 is slightly higher than the fastener elements 6 and 7 (that is, longer in the vertical direction) and may be the same as the height of the connecting column 15 of the cooperating slider 10.
　スライドファスナーが延びる方向に対して直交する横方向で測定した連結柱２３の幅は、左右のテープのどちらのエレメントも止具を通り抜けるのを防ぐのに十分に広くなければならない。従って、連結柱２３の幅は、係合したエレメントの遠位端の間の距離を上回らない幅である。連結柱２３の最小幅は、エレメントが係合している時のテープ間の距離である。 The width of the connecting post 23 measured in the transverse direction perpendicular to the direction in which the slide fastener extends must be wide enough to prevent both elements of the left and right tapes from passing through the stop. Thus, the width of the connecting post 23 is such that it does not exceed the distance between the distal ends of the engaged elements. The minimum width of the connecting post 23 is the distance between the tapes when the elements are engaged.
　スライドファスナーが延びる長さ方向で測定した連結柱２３の長さは、好ましくは、およそ１ｍｍであるとしてよい。 The length of the connecting column 23 measured in the length direction in which the slide fastener extends is preferably about 1 mm.
　また、好ましくは、長さ方向で測定した連結柱２３の長さはスライダーの連結柱の長さよりも小さくしてもよい。 Also preferably, the length of the connecting column 23 measured in the length direction may be smaller than the length of the connecting column of the slider.
　連結柱２３の長さ方向又は縦方向長さは、好ましくは、１つのファスナーエレメントの縦方向の寸法の＋１０％を超えず、より好ましくは＋５％を超えない。 The length direction or the longitudinal direction length of the connecting pillar 23 preferably does not exceed + 10%, and more preferably does not exceed + 5% of the longitudinal dimension of one fastener element.
　止具がエレメント間で安定に保持されていることを保証するために、止具内部での係合したエレメントの回転、垂直及び水平移動を防止しなければならない。 To ensure that the fastener is held stably between the elements, rotation, vertical and horizontal movement of the engaged element within the fastener must be prevented.
　使用時、チェーンのテープが止具に挿入され、係合したエレメントの列の最初のエレメントに止具が接して止具が静止するように、止具を操作できる。 When in use, the stopper can be operated so that the chain tape is inserted into the stopper and the stopper comes into contact with the first element in the row of engaged elements and the stopper stops.
　図示した止具の実施形態において、上翼部及び下翼部の間で連結柱２３の両側に２つの空きスペースが設けられる。この配列により、テープは随意選択で連結柱２３を通り越して出てもよい。 In the illustrated embodiment of the fastener, two empty spaces are provided on both sides of the connecting column 23 between the upper wing and the lower wing. With this arrangement, the tape may optionally pass past the connecting post 23.
　止具は、少なくとも１つのファスナーエレメントをカバーしなければならず、その場合それは協働する係合したエレメントの一部分をカバーする。 The stop must cover at least one fastener element, in which case it covers a portion of the cooperating engaged elements.
　好ましくは、下止具２０の翼部２１，２２は、最初の協働する一対のエレメント６，７を完全にカバーする。更に好ましくは、止具の翼部は、少なくとも二対の協働するエレメントを完全にカバーしてもよい。 Preferably, the wings 21, 22 of the lower stop 20 completely cover the first pair of cooperating elements 6, 7. More preferably, the stop wing may completely cover at least two pairs of cooperating elements.
　随意選択で、翼部の外面及び連結柱の少なくとも一方にロゴなどを組み込んでもよい。 Optionally, a logo or the like may be incorporated into at least one of the outer surface of the wing and the connecting column.
　過度な力でスライダーを止具と接触させた場合、スライダーの翼部が止具の翼部の間に押し込まれ、それにより止具を開放させ得る。これは下止具（即ちスライダーの尾部に当接するように意図された止具）で起こりがちとしてよい。これを防ぐために、スライダー１０の翼部１３，１４に当接する下止具２０の翼部２１，２２の前端部に、スライダーの方向に延びる前端突出部３６をそれぞれ形成してもよい。前端突出部３６の内面は翼部２１，２２の内面と同一面を備えており、前端突出部３６の外面は翼部２１，２２の高さよりも低い。言い換えれば、前端突出部３６は、翼部２１，２２の側面の内側半分からスライダーの方向に延びていてもよい。なお、翼部２１，２２の前端部は、連結柱２３から最も遠い翼部の端部である。 When the slider is brought into contact with the stopper with an excessive force, the slider wing is pushed between the stopper wings, thereby releasing the stopper. This may tend to occur with a lower stop (ie a stop intended to abut the tail of the slider). In order to prevent this, a front end protrusion 36 that extends in the direction of the slider may be formed at the front end of the wings 21 and 22 of the lower stopper 20 that contacts the wings 13 and 14 of the slider 10. The inner surface of the front end protrusion 36 is flush with the inner surfaces of the wings 21 and 22, and the outer surface of the front end protrusion 36 is lower than the height of the wings 21 and 22. In other words, the front end protrusion 36 may extend from the inner half of the side surfaces of the wings 21 and 22 in the direction of the slider. The front end portions of the wing portions 21 and 22 are the end portions of the wing portion farthest from the connecting column 23.
　２つの前端突出部３６のそれぞれは、連結柱２３から離れる方向に収束するとともに、スライダー１０の上翼部１３及び下翼部１４に当接する構成になっている一対の傾斜面３８（図２及び図１３参照）の一方を設けている。この配列により、スライダー１０の翼部１３，１４の尾部が止具に当接する際に、止具の翼部２１，２２はスライダーの翼部１３，１４の間に進入可能である。その結果、止具を更に下に移動させる力がスライダーに加えられた場合、止具は、止具の翼部が互いに近づき開放しないという意味で、更に締め付けられるか、又は閉鎖されることになる。なお、止具を上止具として検討する時も、その翼部に前端突出部３６をそれぞれ形成してもよい。 Each of the two front end projecting portions 36 converges in a direction away from the connecting column 23 and is a pair of inclined surfaces 38 configured to contact the upper wing portion 13 and the lower wing portion 14 of the slider 10 (see FIG. 2 and FIG. 2). One of them is provided (see FIG. 13). With this arrangement, when the tail portions of the wing portions 13 and 14 of the slider 10 come into contact with the stopper, the wing portions 21 and 22 of the stopper can enter between the wing portions 13 and 14 of the slider. As a result, if a force is applied to the slider that moves the stop further down, the stop will be further tightened or closed in the sense that the wings of the stop will not approach each other and open. . When considering the stopper as an upper stopper, the front end protrusions 36 may be formed on the wings.
　実施形態において、下止具２０及びスライダー１０の高さは、止具の上翼部と下翼部との間の垂直距離、及びスライダーの上翼部と下翼部との間の垂直距離と同等であってもよい。この配列により、スライダーが過度に激しく止具に引っ張られ、スライダーの両翼部が止具の翼部の内部又は外部に達した場合に起こり得る、望ましくないくさび動作を防ぐことができる。 In the embodiment, the height of the lower stopper 20 and the slider 10 is such that the vertical distance between the upper wing and the lower wing of the stopper and the vertical distance between the upper wing and the lower wing of the slider. It may be equivalent. This arrangement prevents unwanted wedge motion that can occur if the slider is pulled too hard into the stop and both wings of the slider reach inside or outside the stop wing.
　次に、図１５及び図１６を参照して、本発明に従った下止具を含むスライドファスナーの第２実施形態について説明する。なお、第１実施形態と同一又は同等部分については、図面に同一或いは同等符号を付してその説明を省略或いは簡略化する。 Next, a second embodiment of the slide fastener including the lower stop according to the present invention will be described with reference to FIGS. 15 and 16. Note that portions that are the same as or equivalent to those of the first embodiment are denoted by the same or equivalent reference numerals in the drawings, and description thereof is omitted or simplified.
