Description

スライドファスナエレメントおよびスライドファスナストリンガSlide fastener element and slide fastener stringer
　本発明は、一般にスライドファスナに関するものである。より詳細には、本発明は、改良されたスライドファスナエレメント、およびそのようなスライドファスナエレメントの列からなるスライドファスナストリンガに関するものである。 The present invention generally relates to a slide fastener. More specifically, the present invention relates to an improved slide fastener element and a slide fastener stringer consisting of a row of such slide fastener elements.
　よく知られているように、スライドファスナは、平らに並べられた一対のテープを有する。一対のテープは、紐が取り付けられる内側対向縁を有し、ファスナエレメント（または歯）は、紐とテープの内側縁に取り付けられている。スライダを操作して内側縁同士を近づけると、エレメントが相互に噛み合う。このようにエレメントを取り付けたテープをストリンガという。２つのストリンガを組み合わせたものをチェーンという。スライドファスナは、一般的に、チェーンと、少なくとも１つのスライダと、を有する。多くの場合、チェーンには、上止、下止、またはその両方が取り付けられる。スライドファスナを開閉する際には、通常、スライダに連結されたプルタブを持って、スライダを前方または後方に引く。これにより、スライダの移動方向に応じて、スライドファスナが閉じたり開いたりする。 As is well known, slide fasteners have a pair of flatly arranged tapes. The pair of tapes have an inner facing edge to which the string is attached, and the fastener element (or tooth) is attached to the inner edge of the string and the tape. When you operate the slider to bring the inner edges closer together, the elements mesh with each other. The tape to which the element is attached in this way is called a stringer. A chain is a combination of two stringers. The slide fastener generally has a chain and at least one slider. Chains are often fitted with top stops, bottom stops, or both. When opening and closing the slide fastener, you usually hold the pull tab attached to the slider and pull the slider forward or backward. This causes the slide fasteners to close and open depending on the direction of movement of the slider.
　本発明は、例えば、金属製又は金属合金製のファスナエレメントに関するものである。金属製ファスナエレメントの製造には、いくつかの技術が主に知られている。第１の技術によれば、ファスナエレメントはワイヤから切断される。別の方法として、ファスナエレメントの基本的な形状は、プレス加工によって製造されてもよい。これらの２つの技術は、ファスナエレメントが実質的にＵ字型またはＹ字型に製造された後、紐とテープの縁部にクランプされることを提供する。第３の製造方法は、例えばＣＮ２５２７１３１Ｙに記載されているように、金属製のファスナエレメントをテープに直接射出成形するものである。第４の製造方法は、金属製または樹脂製のファスナエレメントをダイキャストまたは射出成形によって最初に作成し、そのエレメントを紐とテープの縁部にクランプすることを提供する。 The present invention relates to, for example, a fastener element made of metal or a metal alloy. Several techniques are mainly known for the manufacture of metal fastener elements. According to the first technique, the fastener element is cut from the wire. Alternatively, the basic shape of the fastener element may be manufactured by stamping. These two techniques provide that the fastener element is manufactured substantially U-shaped or Y-shaped and then clamped to the edges of the string and tape. The third manufacturing method is, for example, as described in CN25271131Y, in which a metal fastener element is injection-molded directly onto a tape. A fourth manufacturing method provides that a metal or resin fastener element is first made by die casting or injection molding and the element is clamped to the edges of the string and tape.
　ファスナエレメントの初期形状は、成形および／または切断の過程で得られ、その後、エレメントの脚部を変形させてテープに装着する。 The initial shape of the fastener element is obtained in the process of molding and / or cutting, and then the legs of the element are deformed and attached to the tape.
　スライドファスナの業界では、金属製のファスナエレメントの少なくとも使用時に見える表面に、装飾を施すことが求められている。しかし、第１、第２、第３の技術を構成する製造プロセスでは、多くの装飾面を施すことは困難である。 In the slide fastener industry, it is required to decorate at least the surface of the metal fastener element that can be seen at the time of use. However, it is difficult to apply many decorative surfaces in the manufacturing process constituting the first, second, and third techniques.
　また、ファスナエレメントを紐やテープにクランプする動作は、特にダイキャストで得られたファスナエレメントは、エレメントの外面に１つ以上のクラックが発生する可能性が高く、そのクラックはどのような装飾上にも見える可能性がある。 In addition, the operation of clamping the fastener element to a string or tape is particularly likely to cause one or more cracks on the outer surface of the element, especially for the fastener element obtained by die casting. May also look like.
　本発明は、スライドファスナの通常の使用時に見えるエレメントの表面に施された装飾を損なうことなく、テープにクランプすることができる、改良された金属製ファスナエレメントを提供する。これは、ファスナエレメントの基本的な形状がダイキャスト成形によって作られたものであっても同様である。特に本発明は、装飾を施すことが容易な、改良された金属ファスナエレメントを提供する。 The present invention provides an improved metal fastener element that can be clamped to tape without compromising the decoration applied to the surface of the element that is visible during normal use of the slide fastener. This is the same even if the basic shape of the fastener element is made by die casting. In particular, the present invention provides an improved metal fastener element that is easy to decorate.

The connecting portion 43 of the element 40 can be held.
　紐受容空間４６（図２）は、脚部４２の間に画定される。脚部４２は、紐が脚部４２の間の紐受容空間４６に導入される隙間５３をその間に規定する自由端または遠位端５６を有する。 The string receiving space 46 (FIG. 2) is defined between the legs 42. The leg 42 has a free end or a distal end 56 that defines a gap 53 in which the string is introduced into the string receiving space 46 between the legs 42.
　各脚部４２の、対向する他方の脚部４２の側面に面する表面は、内側面と呼ばれる。内側面とは逆側の脚部４２の表面は、外側面と呼ばれる。好ましくは、脚部４２の自由端である遠位端５６は、紐２０に取り付けられたときに、紐２０またはテープ１３またはその両方をしっかりと把持できるように、一方の脚部４２から他方の脚部４２に向かって延びている。図面に示されている例示的な実施形態では、エレメント４０の頭部４１から遠位の脚部４２の端部における脚部４２の内側面は、脚部４２の遠位端５６に曲がりを生じさせる半径を有する。さらに、それぞれの外側面は、相補的な半径を有してもよい。横方向におけるそれぞれの内側面と対向する外側面との間の距離は、変化してもよく、半径に沿った点で特に長くなってもよい。さらに、脚部４２の遠位端５６における半径の追加は、紐受容空間４６を部分的に包囲して部分的に閉じ、隙間５３を狭めてもよい。 The surface of each leg 42 facing the side surface of the other opposite leg 42 is called the inner surface. The surface of the leg 42 opposite to the inner surface is called the outer surface. Preferably, the distal end 56, which is the free end of the leg 42, is from one leg 42 to the other so that when attached to the string 20, the string 20 and / or tape 13 can be firmly gripped. It extends toward the leg 42. In an exemplary embodiment shown in the drawings, the inner surface of the leg 42 at the end of the leg 42 distal to the head 41 of the element 40 causes a bend at the distal end 56 of the leg 42. Has a radius to make. In addition, each outer surface may have complementary radii. The distance between each inner surface and the opposite outer surface in the lateral direction may vary and may be particularly long at points along the radius. Further, the addition of the radius at the distal end 56 of the leg 42 may partially surround and partially close the string receiving space 46 to narrow the gap 53.
　エレメント４０をテープ１３に取り付ける際、脚部４２のそれぞれの遠位端５６は、ファスナテープ１３または紐２０またはその両方を間に挟むように、ファスナテープ１３または紐２０またはその両方に配置される。脚部４２の根元部５０は、互いに対向する対向面５１を有している。これら対向面５１は、一対の脚部４２の内側面の間の面を構成する頭部４１の曲面５２によって接続される。根元部５０の対向面５１は、実質的に直線状であってもよいし、わずかに凹んでいてもよく、曲率は曲面５２の曲率よりもかなり大きい。 When attaching the element 40 to the tape 13, each distal end 56 of the leg 42 is placed on the fastener tape 13 and / or string 20 so as to sandwich the fastener tape 13 and / or string 20 in between. .. The root portion 50 of the leg portion 42 has facing surfaces 51 facing each other. These facing surfaces 51 are connected by a curved surface 52 of the head 41 forming a surface between the inner side surfaces of the pair of legs 42. The facing surface 51 of the root portion 50 may be substantially linear or slightly recessed, and the curvature is considerably larger than the curvature of the curved surface 52.
　脚部４２は、曲面５２を遠位とする脚部４２の遠位端５６の半径の開始まで、またはその直前まで、幅方向に先細りとなっている。装着時に、クランプされたエレメント４０によって紐およびテープに加えられる圧力が、脚部４２が紐２０またはテープ１３と接触して延びる際に変化しないように、幅方向の脚部４２の内側面及び外側面が実質的に平坦またはわずかに凹んでいることが好ましい。 The leg portion 42 is tapered in the width direction until the start of the radius of the distal end 56 of the leg portion 42 having the curved surface 52 as the distal end, or until just before the radius. The inner and outer sides of the leg 42 in the width direction so that the pressure applied to the string and tape by the clamped element 40 during mounting does not change as the leg 42 extends in contact with the string 20 or tape 13. It is preferred that the sides are substantially flat or slightly recessed.
　各脚部４２には、好ましくは、各脚部４２の内側面から反対側の脚部４２に向かって延びる複数の紐係合突起４７、４８、４９が設けられている。紐係合突起４７～４９は、本明細書で後に説明するように、ストリンガの紐２０を係合して保持するためのものである（図８）。 Each leg 42 is preferably provided with a plurality of string engaging protrusions 47, 48, 49 extending from the inner surface of each leg 42 toward the opposite leg 42. The string engaging protrusions 47 to 49 are for engaging and holding the string 20 of the stringer, as will be described later in the present specification (FIG. 8).
　好ましい実施形態によれば、各脚部４２は、曲面５２または頭部４１から距離を置いて配置された第１の紐係合突起４７と、脚部４２の遠位端５６の近くにある少なくとも第２の紐係合突起４８と、を提供する。より好ましくは、各脚部４２は、第１の紐係合突起４７および第２の紐係合突起４８の中間の第３の紐係合突起４９も備える。 According to a preferred embodiment, each leg 42 is at least near a first string engaging projection 47 located at a distance from the curved surface 52 or head 41 and the distal end 56 of the leg 42. A second string engaging projection 48 is provided. More preferably, each leg 42 also includes a third string engaging projection 49 in between the first string engaging projection 47 and the second string engaging projection 48.
　好ましい実施形態によれば、第１の紐係合突起４７は、それらが一体的に取り付けられている脚部４２の内側面から遠くに延びるにつれて、幅方向に徐々に細くなっている。第１の紐係合突起４７は、長さ方向から見たときに実質的に四辺形の形態を生じるように形成されている。好ましくは、当該四辺形は台形である。 According to a preferred embodiment, the first string engaging projections 47 gradually taper in the width direction as they extend farther from the inner surface of the leg 42 to which they are integrally attached. The first string engaging projection 47 is formed so as to form a substantially quadrilateral shape when viewed from the length direction. Preferably, the quadrilateral is trapezoidal.
　さらに好ましくは、図２に示すように、各第１の紐係合突起４７の頭部は、第１の紐係合突起４７の端面４７ａに合わさる２つの側面４７ｂ，４７ｃを有する。好ましくは、側面４７ｂ，４７ｃは、第１の紐係合突起４７の端面４７ａに収束して合わさる傾斜面である。さらに、好ましくは、２つの傾斜した側面４７ｃ，４７ｂは、第１の紐係合突起４７が延びる脚部４２の内側面と鈍角をなす。 More preferably, as shown in FIG. 2, the head of each first string engaging protrusion 47 has two side surfaces 47b, 47c that fit into the end face 47a of the first string engaging protrusion 47. Preferably, the side surfaces 47b and 47c are inclined surfaces that converge and fit on the end surface 47a of the first string engaging projection 47. Further, preferably, the two inclined side surfaces 47c and 47b form an obtuse angle with the inner surface of the leg portion 42 on which the first string engaging projection 47 extends.
　さらに、図８に見られるように、ファスナエレメント４０がスライドファスナ１０のテープ１３の紐２０を把持するとき、一対の第１の係合突起部４７は、曲面５２の頭部から離れるにつれて、その端面４７ａが接近するように突出する。すなわち、対向する第１の紐係合突起４７の間の隙間７０は、横方向に向かって先細りになっている。 Further, as seen in FIG. 8, when the fastener element 40 grips the string 20 of the tape 13 of the slide fastener 10, the pair of first engaging projections 47 are moved away from the head of the curved surface 52. The end face 47a protrudes so as to approach. That is, the gap 70 between the first string engaging protrusions 47 facing each other is tapered in the lateral direction.
　さらに、エレメント４０の頭部４１から遠く離れた各第１の紐係合突起４７の傾斜面４７ｃは、紐受容空間４６（図２）に面しており、ファスナエレメント４０が紐２０を把持すると、傾斜面４７ｃは紐２０の周縁部に接している。図８に示すように、脚部４２の内側面から延びる一対の第１の紐係合突起４７の横方向の幅は、ファスナエレメント４０のクランプ状態において、傾斜面４７ｃのそれぞれが互いに接近して、紐２０の最内周部に接触または係合する障壁を一緒に形成するように選択される。当該障壁によって、曲面５２と、脚部４２の根元部５０の対向面５１と、第１の紐係合突起４７の傾斜面４７ｂと、の間に規定される中空空間または貫通孔５５に、紐２０が入ることが実質的に防止される。なお、図８に示すように、一対の第１の紐係合突起４７によって紐１３のごく一部が挟み込まれていてもよい。 Further, the inclined surface 47c of each first string engaging projection 47 far away from the head 41 of the element 40 faces the string receiving space 46 (FIG. 2), and when the fastener element 40 grips the string 20. The inclined surface 47c is in contact with the peripheral edge of the string 20. As shown in FIG. 8, the lateral width of the pair of first string engaging protrusions 47 extending from the inner surface of the leg portion 42 is such that the inclined surfaces 47c are close to each other in the clamped state of the fastener element 40. , Selected to together form a barrier that contacts or engages with the innermost circumference of the string 20. The barrier creates a string in the hollow space or through hole 55 defined between the curved surface 52, the facing surface 51 of the root portion 50 of the leg portion 42, and the inclined surface 47b of the first string engaging projection 47. 20 is substantially prevented from entering. As shown in FIG. 8, a small part of the string 13 may be sandwiched by the pair of first string engaging projections 47.
　貫通孔５５は、根元部５０と、頭部４１に最も近い位置に配置された第１の紐係合突起４７と、の間に設けられている。 The through hole 55 is provided between the root portion 50 and the first string engaging protrusion 47 arranged at the position closest to the head 41.
　具体的には、貫通孔５５は、頭部４１の曲面５２と、脚部４２の根元部５０の対向面５１と、第１の紐係合突起４７の傾斜面４７ｂと、によって規定される。 Specifically, the through hole 55 is defined by the curved surface 52 of the head 41, the facing surface 51 of the root portion 50 of the leg portion 42, and the inclined surface 47b of the first string engaging projection 47.
　貫通孔５５は、ファスナエレメント４０が紐２０に取り付けられていないときには、紐受容空間４６と連続し、連通している。ファスナエレメント４０の各嵌合空間部４４は、貫通孔５５と連続している。 The through hole 55 is continuous with and communicates with the string receiving space 46 when the fastener element 40 is not attached to the string 20. Each fitting space 44 of the fastener element 40 is continuous with the through hole 55.
　貫通孔５５が設けられていると、クランプ作用による脚部４２の変形やファスナエレメント４０の外面の亀裂の形成を抑えることができるため、脚部４２の横方向の長さを長くすることができる。 When the through hole 55 is provided, it is possible to suppress the deformation of the leg portion 42 and the formation of cracks on the outer surface of the fastener element 40 due to the clamping action, so that the lateral length of the leg portion 42 can be lengthened. ..
　貫通孔５５は、頭部４１における曲面５２と、脚部４２の根元部５０の対向面５１と、第１の紐係合突起４７の傾斜面４７ｂと、ファスナエレメント４０をクランプした後の紐２０と、によって実質的に囲まれている。 The through hole 55 includes a curved surface 52 in the head 41, a facing surface 51 of the root portion 50 of the leg portion 42, an inclined surface 47b of the first string engaging protrusion 47, and a string 20 after clamping the fastener element 40. And are virtually surrounded by.
　図４に示すように、ファスナエレメント４０の結合時には、ファスナエレメント４０の連結部４３は、対向するストリンガの隣接するファスナエレメント４０の嵌合空間部４４に残っており、連結部４３は、貫通孔５５に入り込んでいない。つまり、クランプ後に形成される貫通孔５５の周面の大きさは、連結部４３の全体がそこに入り込むのを妨げるように、連結部４３よりも小さい。 As shown in FIG. 4, when the fastener element 40 is coupled, the connecting portion 43 of the fastener element 40 remains in the fitting space portion 44 of the adjacent fastener element 40 of the facing stringer, and the connecting portion 43 is a through hole. Not in 55. That is, the size of the peripheral surface of the through hole 55 formed after clamping is smaller than that of the connecting portion 43 so as to prevent the entire connecting portion 43 from entering the peripheral surface.
　好ましくは、紐係合突起４７，４８，４９のうちの少なくとも１つ、この例では第１の紐係合突起４７は、長さ方向において、脚部４２の長さ方向の厚さＴ４２または頭部４１の長さ方向の厚さＴ４１よりも小さいまたは狭い厚さまたは大きさを有し、さらに、長さ方向において、根元部５０の長さ方向の厚さＴ５０よりも大きいまたは厚い厚さまたは大きさを有する。この配置により、第１の紐係合突起４７は、ファスナエレメント４０内の紐２０の位置を支持することができる。 Preferably, at least one of the string engaging protrusions 47, 48, 49, in this example the first string engaging protrusion 47, is the length T42 or head of the leg 42 in the length direction. The thickness of the portion 41 in the length direction is smaller or narrower than that of the T41, and the thickness of the root portion 50 is larger or thicker than the thickness T50 in the length direction of the root portion 50. Has a size. With this arrangement, the first string engaging projection 47 can support the position of the string 20 in the fastener element 40.
　さらに、この配置により、第１の紐係合突起４７の厚さが、エレメント４０の脚部４２をファスナテープ１３にクランプするために必要な圧力に影響を与えないことが保証される。 Further, this arrangement ensures that the thickness of the first string engaging projection 47 does not affect the pressure required to clamp the leg 42 of the element 40 to the fastener tape 13.
　第１の紐係合突起４７の寸法は、上記の説明によって限定されないことが理解されるであろう。例えば、その厚さが脚部４２または根元部５０の厚さよりも大きくても小さくても、同様の結果が得られる。また、その他の寸法についても、当業者であれば明らかであろう。ただし、そのような場合には、上述した効果が低下する可能性がある。 It will be understood that the dimensions of the first string engaging projection 47 are not limited by the above description. For example, the same result can be obtained regardless of whether the thickness is larger or smaller than the thickness of the leg portion 42 or the root portion 50. Also, other dimensions will be apparent to those skilled in the art. However, in such a case, the above-mentioned effect may be reduced.
　図示された実施形態では、ストリンガの形成を助けるためにファスナテープ１３にクランプされた後も、第１の紐係合突起４７の端面４７ａの間には隙間７０が存在する。 In the illustrated embodiment, there is a gap 70 between the end faces 47a of the first string engaging projection 47 even after being clamped to the fastener tape 13 to aid in the formation of the stringer.
　実施形態においては、紐２０およびそのテープ１３上にエレメント４０が取り付けられたときに、第１の紐係合突起４７の間の隙間７０が紐２０の方向に徐々に狭まり、結合または結合解除の過程で隣り合うエレメント４０が互いに干渉するのを防ぐようにしてもよい。 In the embodiment, when the element 40 is mounted on the string 20 and its tape 13, the gap 70 between the first string engaging protrusions 47 gradually narrows in the direction of the string 20 to engage or disengage. It may be possible to prevent adjacent elements 40 from interfering with each other in the process.
　上記の配置により、紐２０，２１（図４）は、スライドファスナ１０の閉状態において、反対側のファスナストリンガの隣接するファスナエレメント４０の連結部４３によって係合されることになる嵌合空間部４４から遠ざけられる。 Due to the above arrangement, the strings 20 and 21 (FIG. 4) are engaged by the connecting portion 43 of the adjacent fastener element 40 of the opposite fastener in the closed state of the slide fastener 10. Move away from 44.
　好ましい実施形態によれば、クランプされた第２および第３の紐係合突起４８，４９は、紐２０の中に突出するような形で紐受容空間４６の中心に向かって延びる。 According to a preferred embodiment, the clamped second and third string engaging projections 48, 49 extend toward the center of the string receiving space 46 so as to project into the string 20.
　第２の紐係合突起４８は、第１の紐係合突起４７と脚部４２の遠位端５６との間で脚部４２の内側面から突出し、脚部４２の遠位端５６に隣接し、第１の紐係合突起４７から離れている。 The second string engaging protrusion 48 projects from the inner surface of the leg 42 between the first string engaging protrusion 47 and the distal end 56 of the leg 42 and is adjacent to the distal end 56 of the leg 42. However, it is separated from the first string engaging protrusion 47.
　いくつかの実施形態では、図示された例のように、さらなる第３の紐係合突起４９が、第２の紐係合突起４８と第１の紐係合突起４７との間に設計されてもよい。このようにして、エレメント４０に第３の紐係合突起４９を組み込むことで、エレメント４０の脚部４２の取り付け強度を高めることができる。 In some embodiments, an additional third string engaging projection 49 is designed between the second string engaging projection 48 and the first string engaging projection 47, as in the illustrated example. May be good. In this way, by incorporating the third string engaging projection 49 into the element 40, the attachment strength of the leg portion 42 of the element 40 can be increased.
　第２の紐係合突起４８は、好ましくは、突出方向に先細りのテーパ形状を有する。第２の紐係合突起４８は、エレメント４０の脚部４２の内側面に近い基部では大きく、脚部４２の内側面から離れた自由遠位端では長さ方向に薄くなっている。この先細りの形状により、第２の紐係合突起４８が紐２０に容易に押し込まれ、貫通することができる。好ましくは、第２の紐係合突起４８の体積は、第１の紐係合突起４７の体積よりも小さく、第１の紐係合突起４７よりも少ない範囲で脚部４２の内側面から突出する。 The second string engaging protrusion 48 preferably has a tapered shape that tapers in the protruding direction. The second string engaging projection 48 is large at the base near the inner surface of the leg 42 of the element 40 and thinner in the length direction at the free distal end away from the inner surface of the leg 42. Due to this tapered shape, the second string engaging projection 48 can be easily pushed into the string 20 and penetrated. Preferably, the volume of the second string engaging protrusion 48 is smaller than the volume of the first string engaging protrusion 47 and protrudes from the inner surface of the leg portion 42 in a range smaller than that of the first string engaging protrusion 47. do.
　第３の紐係合突起４９を有する実施形態では、第３の紐係合突起４９は、好ましくは、第１の紐係合突起４７よりも小さな体積を有し、好ましくは、第１の紐係合突起４７よりも少ない範囲で脚部４２の内側面から突出する。 In the embodiment having the third string engaging projection 49, the third string engaging projection 49 preferably has a smaller volume than the first string engaging projection 47, preferably the first string. It protrudes from the inner surface of the leg 42 in a range smaller than that of the engaging protrusion 47.
　図示されていないさらなる実施形態では、第４、第５の紐係合突起など、３つ以上の紐係合突起を含んでいてもよい。これらのさらなる紐係合突起は、第１の紐係合突起４７と第２の紐係合突起４８の間に位置する第３の紐係合突起４９と実質的に同様の寸法で形成されてもよい。このような紐係合突起の配置により、紐２０を保持するためのグリップ力が向上する。 In a further embodiment (not shown), three or more string engaging projections such as the fourth and fifth string engaging projections may be included. These additional string engaging projections are formed in substantially the same dimensions as the third string engaging projection 49 located between the first string engaging projection 47 and the second string engaging projection 48. May be good. By arranging such a string engaging protrusion, the grip force for holding the string 20 is improved.
　好ましくは、紐係合突起４７，４８，４９の少なくとも１つ、この例では第２の紐係合突起４８は、長さ方向の厚さ又は大きさが、脚部４２の長さ方向の厚さＴ４２又は頭部４１の長さ方向の厚さＴ４１よりも小さい又は狭いとともに、長さ方向の厚さ又は大きさが、根元部５０の長さ方向の厚さＴ５０よりも大きい又は厚い。この配置により、第２の紐係合突起４８がファスナエレメント４０内の紐２０の位置を保持することができ、また、エレメント４０がファスナテープ１３と紐２０にクランプされた後に、ファスナエレメント４０に対して紐２０が長さ方向に相対的に移動するのを防止することができる。 Preferably, at least one of the string engaging protrusions 47, 48, 49, in this example the second string engaging protrusion 48, has a thickness or size in the length direction and a thickness in the length direction of the leg portion 42. The thickness or size in the length direction is smaller or narrower than the thickness T41 in the length direction of the T42 or the head 41, and the thickness or size in the length direction is larger or thicker than the thickness T50 in the length direction of the root portion 50. With this arrangement, the second string engaging protrusion 48 can hold the position of the string 20 in the fastener element 40, and after the element 40 is clamped to the fastener tape 13 and the string 20, it becomes the fastener element 40. On the other hand, it is possible to prevent the string 20 from moving relatively in the length direction.
　しかしながら、上述した厚さは、実施形態の説明であり、本開示を限定するものと理解すべきではないことを認識すべきである。第２の紐係合突起４８が第１の紐係合突起４７よりも大きな厚さを有する場合もある。 However, it should be recognized that the thicknesses mentioned above are description of embodiments and should not be understood as limiting this disclosure. The second string engaging projection 48 may have a larger thickness than the first string engaging projection 47.
　さらに、第１の紐係合突起４７と同様に、各第２紐係合突起４８は、脚部４２の内側面から延びる２つの側面４８ｂ、４８ｃを提供してもよい。好ましくは、側面４８ｂ、４８ｃは、各第２の紐係合突起４８の遠位端である端面４８ａに向かって収束して合わさる傾斜面であり、それによって、２つの第２の紐係合突起４８の間のギャップの大きさをわずかに減少させることができる。好ましくは、２つの傾斜した側面４８ｂ、４８ｃは、第２の紐係合突起４８が延びる脚部４２の内側面と鈍角をなす。 Further, similarly to the first string engaging protrusion 47, each second string engaging protrusion 48 may provide two side surfaces 48b and 48c extending from the inner side surface of the leg portion 42. Preferably, the sides 48b, 48c are inclined surfaces that converge and meet towards the end face 48a, which is the distal end of each second string engaging projection 48, thereby the two second string engaging projections. The size of the gap between 48 can be slightly reduced. Preferably, the two inclined side surfaces 48b, 48c form an obtuse angle with the inner surface of the leg 42 on which the second string engaging projection 48 extends.
　第１の紐係合突起４７と同様に、図２に示すように、第３の紐係合突起４９は、長さ方向に見たときに実質的に四辺形のプロファイルを有していてもよく、好ましくは台形である。各第３の紐係合突起４９は、脚部４２の内側面から延び、各第３紐係合突起４９の遠位端４９ａに向かって収束する２つの傾斜面４９ｂ、４９ｃを有してもよい。すなわち、第３紐係合突起４９の幅は、それらが一体的に取り付けられている脚部４２の内側面から離れるほど、幅方向に先細りになっている。 Similar to the first string engaging projection 47, as shown in FIG. 2, the third string engaging projection 49 may have a substantially quadrilateral profile when viewed in the longitudinal direction. Well, preferably trapezoidal. Even if each third string engaging projection 49 has two inclined surfaces 49b, 49c extending from the inner surface of the leg 42 and converging toward the distal end 49a of each third string engaging projection 49. good. That is, the width of the third string engaging protrusion 49 is tapered in the width direction toward the inner surface of the leg portion 42 to which they are integrally attached.
　さらに、２つの傾斜した側面４９ｂ、４９ｃは、好ましくは、第３の紐係合突起４９が延びる脚部４２の内側面と鈍角を形成する。 Further, the two inclined side surfaces 49b and 49c preferably form an obtuse angle with the inner surface of the leg portion 42 on which the third string engaging protrusion 49 extends.
　さらに、第１の紐係合突起４７と同様に、各第３の紐係合突起４９は、第３の紐係合突起４９の遠位端において平坦な遠位端面（または端面）４９ａに収束する２つの傾斜面（または側面）４９ｂ，４９ｃを含んでいてもよく、それによって、２つの対向する第３の紐係合突起４９の間のギャップの大きさをわずかに減少させることができる。 Further, like the first string engaging projection 47, each third string engaging projection 49 converges on a flat distal end face (or end surface) 49a at the distal end of the third string engaging projection 49. The two inclined surfaces (or side surfaces) 49b, 49c may be included, whereby the size of the gap between the two opposing third string engaging protrusions 49 can be slightly reduced.
　第１、第２および第３の紐係合突起４７，４８，４９の傾斜面は、さらに、エレメントがダイキャストによって製造されるときに、ダイからのエレメントの取り出しを助ける。したがって、図１１に示すように、上型６５と下型６６とで金型を形成し、傾斜面は上型６５と下型６６のパーティングラインに沿って頂点に来るように形成してもよい。この製造形態では、紐係合突起４７，４８，４９がファスナエレメント４０の脚部４２の内側面から延びており、当該内側面も同様に、２つの傾斜面が上型と下型のパーティングラインで頂点を形成するように製造されていることが好ましい。このような傾斜面は、ファスナエレメント４０の紐へのグリップを助ける役割も果たす。 The inclined surfaces of the first, second and third string engaging projections 47, 48, 49 further assist in removing the element from the die when the element is manufactured by die casting. Therefore, as shown in FIG. 11, even if the mold is formed by the upper mold 65 and the lower mold 66, and the inclined surface is formed so as to come to the apex along the parting line of the upper mold 65 and the lower mold 66. good. In this manufacturing mode, the string engaging protrusions 47, 48, 49 extend from the inner side surface of the leg portion 42 of the fastener element 40, and the inner side surface also has two inclined surfaces of upper mold and lower mold parting. It is preferably manufactured so as to form vertices on the line. Such an inclined surface also serves to help grip the fastener element 40 to the string.
　すなわち、各紐係合突起４７，４８，４９の少なくとも端面４７ａ，４８ａ，４９ａは、その前後両面からファスナエレメント４０の中心を通る横方向の平面６７に向かって先細りになっている。各紐係合突起４７，４８，４９の先細り形状は、上型および下型からのダイキャストエレメントの取り出しを容易にする。 That is, at least the end faces 47a, 48a, 49a of each string engaging protrusion 47, 48, 49 are tapered from both the front and rear surfaces thereof toward the lateral plane 67 passing through the center of the fastener element 40. The tapered shape of each string engaging protrusion 47, 48, 49 facilitates removal of the die-cast element from the upper and lower dies.
　さらに、各紐係合突起４７，４８，４９の２つの側部の傾斜面４７ｂ，４８ｂ，４９ｂ，４７ｃ，４８ｃ，４９ｃも、互いに向かって、かつファスナエレメント４０の中心面に向かって先細りになっていてもよい。当該テーパは、脚部４２の内側面のいずれかまたはすべて、ならびに紐係合突起４７、４８、４９のいずれかまたはすべての端面または側面に、部分的または全体的に形成されてもよい。 Further, the inclined surfaces 47b, 48b, 49b, 47c, 48c, 49c on the two sides of the string engaging protrusions 47, 48, 49 also taper toward each other and toward the central surface of the fastener element 40. May be. The taper may be partially or wholly formed on any or all of the inner surfaces of the leg 42 and on any or all of the end faces or sides of the string engaging projections 47, 48, 49.
　好ましくは、紐係合突起４７，４８，４９の少なくとも１つ、この例では第３の紐係合突起４９は、長さ方向の厚さまたは大きさが、第１の紐係合突起４７の厚さまたは第２の紐係合突起４８の厚さよりも小さいまたは狭い。また、第３の紐係合突起４９は、長さ方向において、脚部の厚さＴ４２及び／又は頭部の厚さＴ４１よりも小さい又は狭い厚さ又は大きさを有している。 Preferably, at least one of the string engaging projections 47, 48, 49, in this example the third string engaging projection 49, has a thickness or size in the length direction of the first string engaging projection 47. Less than or narrower than the thickness or the thickness of the second string engagement protrusion 48. Further, the third string engaging protrusion 49 has a thickness or size smaller or narrower than the leg thickness T42 and / or the head thickness T41 in the length direction.
　この配置により、ファスナエレメント４０の閉鎖状態において、第３の紐係合突起４９が紐をより容易に貫通することができ、紐がファスナエレメント４０に対して長さ方向に相対的に移動することを防止することができる。 With this arrangement, in the closed state of the fastener element 40, the third string engaging projection 49 can more easily penetrate the string, and the string moves relative to the fastener element 40 in the length direction. Can be prevented.
　図１１に示すように、ファスナエレメント４０をテープ上に直接射出成形することなく、ダイキャスト工程を経て製造することは、比較的複雑な形状を作成することができ、複数の方向に異なる厚さを有する部分を形成することができるため、金型からの離脱を容易にすることができるという点で有利である。 As shown in FIG. 11, manufacturing the fastener element 40 through a die casting process without injection molding directly onto the tape can create relatively complex shapes and have different thicknesses in multiple directions. Since it is possible to form a portion having a portion, it is advantageous in that it can be easily detached from the mold.
　ファスナエレメント４０、特に頭部４１、脚部４２、および各紐係合突起４７、４８、４９の基本的な形状（輪郭）は、ダイキャストプロセスによって形成される。頭部４１から延びる脚部４２の角度は、エレメント４０がファスナストリンガに取り付けられると、より鋭くなる。 The basic shapes (contours) of the fastener element 40, particularly the head 41, the legs 42, and the string engaging protrusions 47, 48, 49 are formed by a die casting process. The angle of the legs 42 extending from the head 41 becomes sharper when the element 40 is attached to the fastener.
　第２の紐係合突起４８は、牽引力に対抗する、すなわち、ファスナエレメント４０がいったん紐にクランプされると紐２０が隙間５３を介して紐受容空間４６から引き出されるのを防止する、というタスクを有する（図８）。 The second string engaging projection 48 opposes the traction force, i.e., the task of preventing the string 20 from being pulled out of the string receiving space 46 through the gap 53 once the fastener element 40 is clamped to the string. (Fig. 8).
　閉じた状態（図８）では、脚部４２の遠位端５６は、好ましくは、その間にテープ１３をクランプする。 In the closed state (FIG. 8), the distal end 56 of the leg 42 preferably clamps the tape 13 in between.
　また、好ましくは、紐係合突起４７，４８，４９のすべてが、脚部４２の長さ方向の厚さＴ４２よりも小さい長さ方向の厚さを有する。この配置により、より強固な取り付けが可能となり、テープ１３に対するエレメント４０の位置をより容易に設定することができ、また、より軽量なエレメント４０を形成することができる。 Also, preferably, all of the string engaging protrusions 47, 48, 49 have a thickness in the length direction smaller than the thickness in the length direction of the leg portion 42 in the length direction. With this arrangement, a stronger attachment is possible, the position of the element 40 with respect to the tape 13 can be set more easily, and a lighter element 40 can be formed.
　添付図面に描かれた例示的な実施形態では、各脚部４２に３つの紐係合突起４７，４８，４９が設けられているが、各脚部４２の紐係合突起４７，４８，４９の数は３つとは異なっていてもよい。 In the exemplary embodiment depicted in the accompanying drawings, each leg 42 is provided with three string engaging projections 47, 48, 49, but each leg 42 is provided with string engaging projections 47, 48, 49. The number of may be different from three.
　さらに、エレメント４０がテープ１３から意図せずに取り外されることができない限り、第１の紐係合突起４７のみで十分であってもよく、同様に第１および第２の紐係合突起４７，４８で十分であってもよい。しかし、場合によっては、さらに紐係合突起が必要になることもあり、例えば、第４および第５の紐係合突起（図示せず）が必要になることもある。これらの変形は、エレメント４０の脚部４２の外面の特に複雑なデザインや、脚部４２の横方向の伸びの変化に対応して必要とされる場合がある。 Further, as long as the element 40 cannot be unintentionally removed from the tape 13, only the first string engaging projection 47 may be sufficient, as well as the first and second string engaging projections 47, 48 may be sufficient. However, in some cases, additional string engaging projections may be required, for example, fourth and fifth string engaging projections (not shown). These modifications may be required in response to particularly complex designs on the outer surface of the legs 42 of the element 40 and changes in lateral elongation of the legs 42.
　紐係合突起４７，４８，４９は、紐係合突起４７，４８，４９が脚部４２の厚さであるため、脚部４２を強化しつつ、紐２０を効果的に保持・把持するという二重のタスクを有している。 Since the string engaging protrusions 47, 48, 49 have the thickness of the leg portion 42, the string engaging protrusions 47, 48, 49 are said to effectively hold and grip the string 20 while strengthening the leg portion 42. Has dual tasks.
　嵌合空間部４４は、脚部４２よりも薄く、したがって、エレメント４０のより弱い、より柔軟な部分を構成している。 The fitting space 44 is thinner than the legs 42 and therefore constitutes a weaker and more flexible portion of the element 40.
　紐２０が紐受容空間４６に導入された後、ファスナエレメント４０の２つの脚部４２を変形させて互いに近づけることにより、ファスナエレメント４０が紐２０にクランプされる。隙間５３は狭くなり、テープ１３の上に閉じられる。表面４７ｃを有する第１の紐係合突起４７は、紐２０が貫通孔５５に実質的に入るのを防ぐ。第２および第３の紐係合突起４８，４９は、紐２０を貫通することができる。嵌合空間部４４よりも相対的に厚くて硬いので、脚部４２は、クランプ工程中に顕著には曲がらない。曲げ応力と変形は、より薄い嵌合空間部４４の領域と、脚部４２と頭部４１の接合部にある曲面５２と、にほぼ集中してかかる。このように、エレメント４０の形状により、エレメント４０の特定の箇所や領域に応力が集中することがない。その結果、脚部４２にクランプ作用によるクラックが発生しない。より具体的には、脚部４２の外面５７に亀裂が生じることはない。したがって、外面５７が損傷することはなく、その上に適用される装飾も損傷しない。 After the string 20 is introduced into the string receiving space 46, the fastener element 40 is clamped to the string 20 by deforming the two legs 42 of the fastener element 40 and bringing them closer to each other. The gap 53 is narrowed and closed on the tape 13. The first string engaging projection 47 having the surface 47c prevents the string 20 from substantially entering the through hole 55. The second and third string engaging projections 48, 49 can penetrate the string 20. Since it is relatively thicker and harder than the fitting space 44, the legs 42 do not bend significantly during the clamping process. The bending stress and deformation are substantially concentrated on the region of the thinner fitting space 44 and the curved surface 52 at the joint between the leg 42 and the head 41. As described above, due to the shape of the element 40, stress is not concentrated on a specific place or region of the element 40. As a result, the leg portion 42 does not crack due to the clamping action. More specifically, the outer surface 57 of the leg 42 is not cracked. Therefore, the outer surface 57 is not damaged, nor is the decoration applied on it damaged.
　図１２、１３および１４では、ファスナエレメント４０の外面に施される装飾の例が示されている。図１２では、脚部４２の外面７１は丸みを帯びているが、図１３および１４では、絵やロゴなどの装飾画像を表示するようにデザインできる凹凸が形成されている。図１３のファスナエレメント４０の脚部４２は、装飾的なレリーフ６８を提供しており、一方、図１４のファスナエレメント４０の脚部４２は、装飾的な凹部６９を提供している。これらの装飾的特徴は、ダイケース成形の使用によって得られる。 FIGS. 12, 13 and 14 show examples of decorations applied to the outer surface of the fastener element 40. In FIG. 12, the outer surface 71 of the leg portion 42 is rounded, but in FIGS. 13 and 14, unevenness that can be designed to display a decorative image such as a picture or a logo is formed. The leg 42 of the fastener element 40 of FIG. 13 provides a decorative relief 68, while the leg 42 of the fastener element 40 of FIG. 14 provides a decorative recess 69. These decorative features are obtained by the use of die case molding.
　頭部４１のデザインは、要求に応じて変化してもよい。図２～８に示す例示的な実施形態では、ファスナエレメント４０の頭部４１は、曲面５２および貫通孔５５に隣接する連結部４３を提供する。頭部４１の縁部５８は、曲面５２および貫通孔５５に沿って連結部４３を部分的に取り囲む。頭部４１の縁部５８は、各連結部４３の周囲に長さ方向に直交する平坦な面を備えている。 The design of the head 41 may be changed according to the request. In an exemplary embodiment shown in FIGS. 2-8, the head 41 of the fastener element 40 provides a connecting portion 43 adjacent to a curved surface 52 and a through hole 55. The edge 58 of the head 41 partially surrounds the connecting portion 43 along the curved surface 52 and the through hole 55. The edge portion 58 of the head portion 41 is provided with a flat surface orthogonal to the length direction around each connecting portion 43.
　図９の例示的な実施形態によれば、連結部４３は、曲面５２および貫通孔５５に隣接している。縁部５８は設けられていない。特に、脚部４２から最も遠い曲面５２は、連結部４３のうち頭部４１から突出して脚部４２に最も近い部分よりも、脚部４２側から遠い部分に形成されている。すなわち、図９に示すように、連結部４３は、その一部が切断されるように形成されている。連結部４３は、頭部４１の端部から延びている。 According to the exemplary embodiment of FIG. 9, the connecting portion 43 is adjacent to the curved surface 52 and the through hole 55. The edge 58 is not provided. In particular, the curved surface 52 farthest from the leg 42 is formed in a portion of the connecting portion 43 that protrudes from the head 41 and is farther from the leg 42 side than the portion closest to the leg 42. That is, as shown in FIG. 9, the connecting portion 43 is formed so that a part thereof is cut off. The connecting portion 43 extends from the end of the head 41.
　図１０の代替実施形態では、連結部４３は、端縁５８を形成するプレート部分から出て、連結部４３を完全に取り囲む。連結部４３は、曲面５２および貫通孔５５から間隔を置いて配置されている。 In the alternative embodiment of FIG. 10, the connecting portion 43 exits from the plate portion forming the edge 58 and completely surrounds the connecting portion 43. The connecting portion 43 is arranged at a distance from the curved surface 52 and the through hole 55.
　好ましくは、紐係合突起４７、４８、４９は、割れないように、また、ダイからのエレメント４０の取り出しを容易にするために、鋭利ではなく、丸みを帯びた角やエッジを有している。 Preferably, the string engagement projections 47, 48, 49 have rounded corners or edges rather than sharp edges to prevent cracking and to facilitate removal of the element 40 from the die. There is.
　代替実施形態（図示せず）では、脚部４２の遠位端５６が、嵌合空間部４４に近接する脚部４２の部分よりも長さ方向の厚さが小さくてもよい。 In an alternative embodiment (not shown), the distal end 56 of the leg 42 may be thinner in the length direction than the portion of the leg 42 adjacent to the fitting space 44.
　図示されていない代替実施形態では、紐係合突起４７，４８，４９が、脚部４２の内側面に沿って千鳥状に配置されることを規定してもよい。 In an alternative embodiment not shown, it may be specified that the string engaging projections 47, 48, 49 are arranged in a staggered manner along the inner surface of the leg 42.
　スライドファスナエレメント４０およびスライドファスナストリンガの多数の態様および実施形態を説明してきた。各態様および実施形態は、任意の他の態様または実施形態と組み合わせ可能であることを理解されたい。さらに、本発明は記載された実施形態に限定されるものではなく、添付の特許請求の範囲およびその法的均等物の範囲内で変化させることができる。 Many aspects and embodiments of the slide fastener element 40 and the slide fastener stringer have been described.
