In principle, duplicate descriptions between the embodiments are omitted. The reference drawings are mainly for description of the invention, and may be simplified for convenience of drawing.
 以下においては、次のように説明される「方向用語」を用いて説明が展開される。前後方向がスライダーの摺動方向に一致する。スライダーの前進により左右のファスナーストリンガーが閉じられ、左右のファスナーエレメントが噛み合う。スライダーの後進により左右のファスナーストリンガーが開けられ、左右のファスナーエレメントの噛合いが解除される。左右方向は、前後方向に直交する方向であり、またスライダーの案内柱にも直交する方向である。上下方向は、前後方向及び左右方向に直交する方向である。上下方向は、スライダーの案内柱が延びる方向に一致する。上下方向は、ファスナーテープのテープ面に直交する方向でもある。なお、ファスナーテープは、上面と下面として一対のテープ面を有する。 In the following, the explanation is developed using “direction terms” explained as follows. The front-rear direction matches the sliding direction of the slider. As the slider advances, the left and right fastener stringers are closed, and the left and right fastener elements engage. The left and right fastener stringers are opened by the backward movement of the slider, and the engagement of the left and right fastener elements is released. The left-right direction is a direction orthogonal to the front-rear direction, and is also a direction orthogonal to the guide column of the slider. The up-down direction is a direction orthogonal to the front-rear direction and the left-right direction. The vertical direction coincides with the direction in which the guide column of the slider extends. The vertical direction is also a direction orthogonal to the tape surface of the fastener tape. The fastener tape has a pair of tape surfaces as an upper surface and a lower surface.

 図1及び図2に示すように、スライドファスナー700は、左右一対のファスナーストリンガー400、及び左右一対のファスナーストリンガー400を開閉するためのスライダー500を有する。各ファスナーストリンガー400は、ファスナーテープ100と、ファスナーテープ100の側縁部150に沿って設けられたファスナーエレメント200、ファスナーテープ100の側縁部150に設けられた樹脂製の前止め300、及びファスナーテープ100の側縁部150に設けられた樹脂又は金属製の後止め600を有する。後止め600が左右のファスナーストリンガー400に共通であり、これにより左右のファスナーストリンガー400が後端側において連結されている。 1 and 2, the slide fastener 700 includes a pair of left and right fastener stringers 400 and a slider 500 for opening and closing the pair of left and right fastener stringers 400. Each fastener stringer 400 includes a fastener tape 100, a fastener element 200 provided along the side edge 150 of the fastener tape 100, a resin front stopper 300 provided on the side edge 150 of the fastener tape 100, and a fastener A back end 600 made of resin or metal is provided on the side edge 150 of the tape 100. The back stop 600 is common to the left and right fastener stringers 400, whereby the left and right fastener stringers 400 are connected on the rear end side.
 スライダー500は、図11及び図12に図示のごとく、上翼板510、下翼板520、案内柱530、フランジ部540、引手取付柱550、引手560を有する。上翼板510と下翼板520が案内柱530を介して連結し、上翼板510と下翼板520が互いに平行に配される。上翼板510の上面視形状と下翼板520の下面視形状が同一である。上翼板510、下翼板520、案内柱530、及びフランジ部540によってファスナーエレメント200のためのY字状のエレメント通路が定められる。フランジ部540は、上翼板510の左右の各側縁部から下方に延びる上部フランジ部と、下翼板520の左右の各側縁部から上方に延びる下部フランジ部を含む。幾つかの実施形態においては上部フランジ部及び下部フランジ部の一方が省略される。引手取付柱550は、上翼板510の上面上に片持ち状に設けられる。引手560は、引手取付柱550に挿通される開口を有する。 11 and 12, the slider 500 includes an upper blade plate 510, a lower blade plate 520, a guide post 530, a flange portion 540, a pull attachment column 550, and a pull handle 560. The upper wing plate 510 and the lower wing plate 520 are connected via the guide column 530, and the upper wing plate 510 and the lower wing plate 520 are arranged in parallel to each other. The top view shape of the upper wing plate 510 and the bottom view shape of the lower wing plate 520 are the same. The upper blade plate 510, the lower blade plate 520, the guide post 530, and the flange portion 540 define a Y-shaped element passage for the fastener element 200. The flange portion 540 includes an upper flange portion that extends downward from the left and right side edges of the upper blade plate 510 and a lower flange portion that extends upward from the left and right side edges of the lower blade plate 520. In some embodiments, one of the upper flange portion and the lower flange portion is omitted. The pulling attachment column 550 is provided in a cantilevered manner on the upper surface of the upper wing plate 510. The pull handle 560 has an opening inserted through the pull handle attachment column 550.
 各ファスナーテープ100は、ファスナーエレメント200が側縁部150に設けられていない第1領域110、ファスナーエレメント200が側縁部150に設けられている第2領域120、及び前止め300が側縁部150に設けられている第3領域130を有する。第1領域110と第2領域120の間に第3領域130が設けられる。つまり、各前止め300は、ファスナーエレメント200が側縁部150に設けられていない第1領域110と、ファスナーエレメント200が側縁部150に設けられている第2領域120の間に設けられる。 Each fastener tape 100 includes a first region 110 in which the fastener element 200 is not provided on the side edge 150, a second region 120 in which the fastener element 200 is provided on the side edge 150, and a front stop 300 on the side edge. 150 has a third region 130 provided at 150. A third region 130 is provided between the first region 110 and the second region 120. That is, each front stop 300 is provided between the first region 110 where the fastener element 200 is not provided on the side edge 150 and the second region 120 where the fastener element 200 is provided on the side edge 150.
 各ファスナーテープ100の第1領域110は、スライドファスナー700を他の物品にしっかりと縫い付けた場合に有用であることが予期される。図2は、左右のファスナーストリンガー400がY字状に連結した状態を示し、左右の第1領域110の間に間隔W110が存在することを示す。この左右の第1領域110の間の間隔W110が、本実施形態に係る前止め300の採用により低減されることが予期される。なお、各ファスナーテープ100の第1領域110の前後長さは必ずしも一致する必要はない。各ファスナーテープ100の第2領域120の前後長さは、実施形態間において様々である。 The first region 110 of each fastener tape 100 is expected to be useful when the slide fastener 700 is firmly sewn to another article. FIG. 2 shows a state in which the left and right fastener stringers 400 are connected in a Y-shape, and shows that there is a space W110 between the left and right first regions 110. It is expected that the interval W110 between the left and right first regions 110 is reduced by employing the front stop 300 according to the present embodiment. In addition, the front-rear length of the first region 110 of each fastener tape 100 does not necessarily need to match. The front-rear length of the second region 120 of each fastener tape 100 varies between the embodiments.
 各ファスナーテープ100は、糸が織られて成る織物若しくは糸が編まれて成る編物である。各ファスナーテープ100は、上面及び下面として一対のテープ面を有する可撓性部材である。各ファスナーテープ100は、テープ主部140とテープ主部140の側縁にある側縁部150を含む。各ファスナーテープ100の側縁部150は、左右他方のファスナーテープ100の側縁部150に対向し、従って、時折、対向側縁部とも呼ばれる。幾つかの実施形態においては側縁部150がテープ主部140よりも厚みが大きい部分を含み、幾つかの実施形態においては側縁部150が芯紐155を含むが、必ずしもこの限りではない。 Each fastener tape 100 is a woven fabric formed by woven yarn or a knitted fabric formed by knitting yarn. Each fastener tape 100 is a flexible member having a pair of tape surfaces as an upper surface and a lower surface. Each fastener tape 100 includes a tape main portion 140 and a side edge portion 150 on a side edge of the tape main portion 140. The side edge 150 of each fastener tape 100 faces the side edge 150 of the other left and right fastener tape 100, and is therefore sometimes referred to as the opposite side edge. In some embodiments, the side edge 150 includes a portion that is thicker than the tape main portion 140, and in some embodiments, the side edge 150 includes a core string 155, but this is not necessarily the case.
 ファスナーテープ100の内側に向かう方向をファスナーテープ内方、略してテープ内方と呼ぶ場合がある。ファスナーテープ100の外側に向かう方向をファスナーテープ外方、略してテープ外方と呼ぶ場合がある。分かりやすい一例としては、テープ内方は、ファスナーテープ100のテープ面の外にある位置からファスナーテープの側縁部を通過してファスナーテープ100のテープ面上に向かう方向である。テープ外方は、ファスナーテープ100のテープ面上にある位置からファスナーテープの側縁部を通過してファスナーテープ100のテープ面の外にある位置に向かう方向である。ファスナーテープのテープ面内においてもテープ内方及びテープ外方との用語が意味する方向が同様に理解されるだろう。 The direction toward the inside of the fastener tape 100 may be referred to as the fastener tape inner side, or the tape inner side for short. A direction toward the outside of the fastener tape 100 may be referred to as a fastener tape outward, abbreviated as tape outward. As an easy-to-understand example, the inside of the tape is a direction from the position outside the tape surface of the fastener tape 100 to the side of the fastener tape toward the tape surface of the fastener tape 100. The tape outward direction is a direction from a position on the tape surface of the fastener tape 100 toward a position outside the tape surface of the fastener tape 100 through the side edge of the fastener tape. In the tape surface of the fastener tape, the directions of the terms “tape inward” and “tape outward” will be similarly understood.
 ファスナーテープ100の側縁部150にはファスナーエレメント200が設けられる。ファスナーエレメント200としてコイルエレメントが図示されているが、これに限定されるべきではない。幾つかの実施形態においては、ファスナーエレメントとして樹脂エレメントや金属エレメントが採用される。ファスナーエレメントの種類に依存することなく、本願に開示の実施形態の利益が享受されるものと理解される。 Fastener element 200 is provided on side edge 150 of fastener tape 100. Although a coil element is illustrated as the fastener element 200, it should not be limited to this. In some embodiments, a resin element or a metal element is employed as the fastener element. It is understood that the benefits of the embodiments disclosed herein are enjoyed without depending on the type of fastener element.
 ファスナーエレメント200は、係合部210と基部220を有する。係合部210は、相手側のファスナーエレメント200に係合可能な部分である。基部220は、ファスナーエレメント200の係合部210よりもテープ内方に位置し、ファスナーテープ100に対するファスナーエレメント200の取り付けを確保するための部分である。当業者が理解するように、係合部210がスライダー500の案内柱530に接触可能であり、基部220がスライダー500のフランジ部540に接触可能である。 The fastener element 200 has an engaging part 210 and a base part 220. The engaging portion 210 is a portion that can engage with the mating fastener element 200. The base 220 is a portion that is located on the inner side of the tape with respect to the engaging portion 210 of the fastener element 200, and for securing the attachment of the fastener element 200 to the fastener tape 100. As understood by those skilled in the art, the engaging portion 210 can contact the guide column 530 of the slider 500, and the base portion 220 can contact the flange portion 540 of the slider 500.
 図示例に係るファスナーエレメント200は、コイルエレメントであり、モノフィラメントが螺旋状に巻かれて構成される。ファスナーエレメント200は、基本ユニットが前後方向に連続して構成される。各基本ユニットは、前後方向に幅広に構成された係合頭部231、係合頭部231の上端に連結する上部脚部232、係合頭部231の下端部に連結する下部脚部233、及び下部脚部233の他端に連結し、隣接する基本ユニットの上部脚部の他端に連結する反転部234を含む。係合頭部231は、ファスナーテープ100の側縁部150上には存在しない。上部脚部232及び下部脚部233が、ファスナーテープ100の側縁部150の芯紐155を横切り、テープ内方に延びる。 The fastener element 200 according to the illustrated example is a coil element and is configured by winding a monofilament in a spiral shape. The fastener element 200 is configured such that basic units are continuous in the front-rear direction. Each basic unit includes an engaging head 231 configured to be wide in the front-rear direction, an upper leg 232 connected to the upper end of the engaging head 231, a lower leg 233 connected to the lower end of the engaging head 231, And an inversion part 234 connected to the other end of the lower leg part 233 and connected to the other end of the upper leg part of the adjacent basic unit. The engaging head 231 does not exist on the side edge 150 of the fastener tape 100. The upper leg 232 and the lower leg 233 cross the core string 155 of the side edge 150 of the fastener tape 100 and extend inward of the tape.
 ファスナーエレメント200の幅W200は、お互いに平行である第1仮想面PL1及び第2仮想面PL2により定められる。図3及び図6に示すように、第1仮想面PL1には、最もテープ外方に位置する各係合部210の点又は面が配される。第2仮想面PL2には、最もテープ内方に位置する各基部220の点又は面が同一平面内に配される。 The width W200 of the fastener element 200 is determined by the first virtual plane PL1 and the second virtual plane PL2 that are parallel to each other. As shown in FIGS. 3 and 6, the first virtual plane PL <b> 1 is provided with a point or a plane of each engaging portion 210 that is located most outward from the tape. On the second virtual plane PL2, the points or planes of the respective bases 220 located most inside the tape are arranged in the same plane.
 換言すれば、第1仮想面PL1には、ファスナーテープ100の側縁部150から最も離れた各係合部210の点又は面が配される。第2仮想面PL2には、各係合部210から最も離れた各基部220の点又は面が配される。 In other words, the point or surface of each engaging portion 210 that is farthest from the side edge portion 150 of the fastener tape 100 is disposed on the first virtual surface PL1. On the second virtual plane PL2, the point or surface of each base 220 farthest from each engaging portion 210 is disposed.
 図示例に係るコイルエレメントにおいては、各係合頭部231の平坦面が第1仮想面PL1に配される。各反転部234の最もテープ内方に位置する点が第2仮想面PL2に配される。 In the coil element according to the illustrated example, the flat surface of each engagement head 231 is arranged on the first virtual plane PL1. A point of each reversing portion 234 located at the innermost side of the tape is arranged on the second virtual plane PL2.
 スライドファスナー700を基準とする場合、第1仮想面PL1は、ファスナーエレメント200の左右内側の境界を定める。第2仮想面PL2は、ファスナーエレメント200の左右外側の境界を定める。 When the slide fastener 700 is used as a reference, the first virtual plane PL1 defines the left and right inner boundaries of the fastener element 200. The second virtual plane PL2 defines the left and right outer boundaries of the fastener element 200.
 各前止め300は、三日月状の上面視形状を有する。各前止め300は、第1領域110を臨む前面310、第2領域120を臨む後面320、前面310と後面320を結び、テープ外方を臨む第1側面330、前面310と後面320を結び、テープ内方を臨む第2側面340を有する。各前止め300は、ファスナーテープ100のテープ上面101から離間して配される上面350を有し、またファスナーテープ100のテープ下面102に面一の下面360を有する。第1側面330と前面310の間には丸み付けられた縁部が存在し、第1側面330と後面320の間には丸み付けられた縁部が存在する。 Each front stop 300 has a crescent-shaped top view. Each front stop 300 connects the front surface 310 facing the first region 110, the rear surface 320 facing the second region 120, the front surface 310 and the rear surface 320, the first side surface 330 facing the outside of the tape, the front surface 310 and the rear surface 320, It has the 2nd side 340 which faces the inside of a tape. Each front stop 300 has an upper surface 350 that is spaced apart from the tape upper surface 101 of the fastener tape 100, and has a lower surface 360 that is flush with the tape lower surface 102 of the fastener tape 100. A rounded edge exists between the first side surface 330 and the front surface 310, and a rounded edge portion exists between the first side surface 330 and the rear surface 320.
 各前止め300は、非限定の形態においては、インサート成形に基づいてファスナーテープ100の側縁部150に対して一体的に成形される。左側前止め300の前後長は、右側前止め300の前後長よりも大きい。左側前止め300は、右側前止め300よりもファスナーテープ100の側縁部150に沿って長く延びる。 Each front stop 300 is integrally formed with respect to the side edge 150 of the fastener tape 100 based on insert molding in a non-limiting form. The front-rear length of the left front stop 300 is larger than the front-rear length of the right front stop 300. The left front stop 300 extends longer along the side edge 150 of the fastener tape 100 than the right front stop 300.
 図3に示す左側前止め300の第1側面330の後方領域には、第1仮想面PL1を越えてファスナーテープ内方に窪んだ凹状係合部390が設けられる。凹状係合部390は、第1仮想面PL1に交差する側面391を有する。 In the rear region of the first side surface 330 of the left front stop 300 shown in FIG. 3, a concave engagement portion 390 that is recessed inward of the fastener tape beyond the first virtual surface PL1 is provided. Concave engagement portion 390 has a side surface 391 that intersects first virtual surface PL1.
 図6に示す右側前止め300の第1側面330の後方領域には第1仮想面PL1を越えてファスナーテープ外方に突出した凸状係合部380が設けられる。凸状係合部380は、第1仮想面PL1に交差する2つの側面381を有する。 6 is provided in the rear region of the first side surface 330 of the right front stop 300 shown in FIG. 6 with a convex engagement portion 380 projecting outward from the fastener tape beyond the first virtual surface PL1. The convex engagement portion 380 has two side surfaces 381 that intersect the first virtual plane PL1.
 スライダー500の前進により左右の前止め300がスライダー内に収容される時、左側前止め300の凹状係合部390と右側前止め300の凸状係合部380が係合及び接触し、左側前止め300には時計回りの回転力が付与され、右側前止め300には反時計周りの回転力が付与される。左右の各前止め300の第2側面340には、その前方領域から後方領域に亘って第2仮想面PL2に近接するように傾斜して延びる傾斜面345が含まれ、従って、各前止め300の第2側面340がスライダー500のフランジ部540の内壁面に接触するまで各前止め300の回転が許容される。 When the left and right front stops 300 are accommodated in the slider by the advance of the slider 500, the concave engagement portion 390 of the left front stop 300 and the convex engagement portion 380 of the right front stop 300 are engaged and contacted, and the left front stop The stop 300 is given a clockwise rotational force, and the right front stop 300 is given a counterclockwise rotational force. The second side surface 340 of each of the left and right front stops 300 includes an inclined surface 345 extending from the front region to the rear region so as to approach the second virtual surface PL2, and accordingly, each front stop 300 is provided. Each front stop 300 is allowed to rotate until the second side surface 340 contacts the inner wall surface of the flange portion 540 of the slider 500.
 なお、前止め300の前方領域及び後方領域は相対的なものである。例えば、図示例の場合、前止め300の前方領域が、前止め300の前後方向の中心よりも前方にある領域である。前止め300の後方領域が、前止め300の前後方向の中心よりも後方にある領域である。前止め300の前後方向の中心から前後方向にややシフトした点に照らして前方及び後方領域が規定され得る。 Note that the front region and the rear region of the front stop 300 are relative. For example, in the illustrated example, the front region of the front stop 300 is a region that is ahead of the center of the front stop 300 in the front-rear direction. The rear region of the front stop 300 is a region located behind the center of the front stop 300 in the front-rear direction. The front and rear regions can be defined in light of a point slightly shifted in the front-rear direction from the front-rear center of the front stop 300.
 この各前止め300の回転により図2に示す間隔W110が減じられる。図2に示す間隔W110の減少により、閉状態のスライドファスナー700の外観が改善され、又は縫製し易さも確保され、又はスライダー500の良好な始動性が確保される。スライダーの始動性は、停止状態のスライダーを動かすことの容易性に等しい。 The interval W110 shown in FIG. 2 is reduced by the rotation of each of the front stops 300. By reducing the interval W110 shown in FIG. 2, the appearance of the closed slide fastener 700 is improved, the ease of sewing is ensured, or the good startability of the slider 500 is secured. The startability of the slider is equal to the ease of moving the slider in the stopped state.
 図3及び図6に示すように、図示例に係る各前止め300は、前面310と第2側面340の間に第2仮想面PL2を越えてテープ内方に突出する丸み付けられた第1縁部371を有する。第1縁部371が第2側面340よりもテープ内方に位置し、第2側面340は、後方に延びるに応じて第2仮想面PL2に近接するように延びる。図3に示す左側前止め300においては、第2側面340の傾斜面345が、後方に延在する過程において第2仮想面PL2を交差する。この時、傾斜面345と第2仮想面PL2とが交差する点を交差点とすると、交差点よりも前方において傾斜面345は第2仮想面PL2よりもテープ内方に位置し、交差点よりも後方において傾斜面345は第2仮想面PL2よりもテープ外方に位置する。図6に示す右側前止め300においては、第2側面340の傾斜面345が、後方に延在する過程において第2仮想面PL2に交差しない。しかしながら、他の実施形態においては、右側前止め300の傾斜面345が第2仮想面PL2に交差し得る。 As shown in FIGS. 3 and 6, each front stop 300 according to the illustrated example has a rounded first protrusion that protrudes inward from the front surface 310 and the second side surface 340 beyond the second virtual surface PL <b> 2. It has an edge 371. The first edge portion 371 is positioned inward of the tape with respect to the second side surface 340, and the second side surface 340 extends closer to the second virtual surface PL2 as it extends rearward. In the left front stop 300 shown in FIG. 3, the inclined surface 345 of the second side surface 340 intersects the second virtual surface PL2 in the process of extending backward. At this time, if a point where the inclined surface 345 and the second virtual surface PL2 intersect is defined as an intersection, the inclined surface 345 is located inward of the tape from the second virtual surface PL2 in front of the intersection and behind the intersection. The inclined surface 345 is located outside the tape with respect to the second virtual surface PL2. In the right front stop 300 shown in FIG. 6, the inclined surface 345 of the second side surface 340 does not intersect the second virtual surface PL2 in the process of extending backward. However, in other embodiments, the inclined surface 345 of the right front stop 300 may intersect the second virtual surface PL2.
 図3に示す左側前止め300の第2側面340の傾斜面345が丸み付けられた第2縁部376を介して後面320に結合する。図6に示す右側前止め300の第2側面340の傾斜面345が丸み付けられた第2縁部376を介して後面320に結合する。右側前止め300の第2側面340の傾斜面345と第2縁部376の境界377が第2仮想面PL2上にある若しくは第2仮想面PL2の近傍にある。右側前止め300の第2縁部376が第2仮想面PL2に交差する。 3 is coupled to the rear surface 320 via a second edge 376 in which the inclined surface 345 of the second side surface 340 of the left front stop 300 shown in FIG. The inclined surface 345 of the second side surface 340 of the right front stop 300 shown in FIG. 6 is coupled to the rear surface 320 via a rounded second edge 376. The inclined surface 345 of the second side surface 340 of the right front stop 300 and the boundary 377 of the second edge 376 are on the second virtual surface PL2 or in the vicinity of the second virtual surface PL2. The second edge 376 of the right front stop 300 intersects the second virtual plane PL2.
 図3及び図6に示すように各前止め300の第1側面330の前方領域にはテープ外方に突出した丸み付けられた隆起部372が設けられる。隆起部372は、スライダー500の案内柱530に接触可能に構成される。図3に示す左側前止め300においては、隆起部372が第1仮想面PL1を越えてテープ外方に突出せず、隆起部372の最もテープ外方の位置が第1仮想面PL1上にある。他方、図6に示す右側前止め300においては、隆起部372が第1仮想面PL1を越えてテープ外方に突出する。スライダー500の案内柱530とフランジ部540の間の間隔を十分に閉塞することが担保される。 As shown in FIGS. 3 and 6, a rounded raised portion 372 protruding outward from the tape is provided in the front region of the first side surface 330 of each front stop 300. The raised portion 372 is configured to be able to contact the guide column 530 of the slider 500. In the left front stop 300 shown in FIG. 3, the raised portion 372 does not protrude outward from the tape beyond the first virtual surface PL1, and the most outward position of the raised portion 372 is on the first virtual surface PL1. . On the other hand, in the right front stop 300 shown in FIG. 6, the raised portion 372 protrudes outward of the tape beyond the first virtual plane PL1. It is ensured that the interval between the guide column 530 and the flange portion 540 of the slider 500 is sufficiently closed.
 各前止め300の第1側面330の後方領域には第1仮想面PL1を越えてテープ外方に突出する突出部が設けられる。図3に示す左側前止め300においては、第1側面330の後方領域に突出部373が設けられ、この突出部373の前方に隣接して上述の凹状係合部390が設けられる。突出部373は、第1仮想面PL1よりもテープ外方に突出する。凹状係合部390の前方に隣接して傾斜面375が設けられる。この傾斜面375の前方に隣接して窪み374が設けられる。窪み374の前方に隣接して上述の隆起部372が設けられる。 In the rear region of the first side surface 330 of each front stop 300, a protruding portion that protrudes outward from the tape beyond the first virtual surface PL1 is provided. In the left front stop 300 shown in FIG. 3, a protruding portion 373 is provided in the rear region of the first side surface 330, and the above-described concave engaging portion 390 is provided adjacent to the front of the protruding portion 373. The protrusion 373 protrudes outward of the tape from the first virtual surface PL1. An inclined surface 375 is provided adjacent to the front of the concave engaging portion 390. A recess 374 is provided adjacent to the front of the inclined surface 375. The above-described raised portion 372 is provided adjacent to the front of the recess 374.
 図6に示す右側前止め300においては、第1側面330の後方領域に上述の凸状係合部380が設けられ、この凸状係合部380の前方に隣接して傾斜面375が設けられる。傾斜面375の前方に隣接して窪み374が設けられる。窪み374の前方に隣接して上述の隆起部372が設けられる。 In the right front stop 300 shown in FIG. 6, the convex engagement portion 380 described above is provided in the rear region of the first side surface 330, and the inclined surface 375 is provided adjacent to the front of the convex engagement portion 380. . A recess 374 is provided adjacent to the front of the inclined surface 375. The above-described raised portion 372 is provided adjacent to the front of the recess 374.
 隆起部372がスライダー500の案内柱530とフランジ部540の間の開口を閉鎖する。隆起部372が上面視して丸み付けられ、隆起部372と案内柱530間の小さい接触抵抗が達成される。窪み374により前止め300の第1側面330と案内柱530の接触面積が低減される。傾斜面375により案内柱530とフランジ部540の間における前止め300の安定した変位が促進される。 The raised portion 372 closes the opening between the guide column 530 and the flange portion 540 of the slider 500. The raised portion 372 is rounded when viewed from above, and a small contact resistance between the raised portion 372 and the guide column 530 is achieved. The depression 374 reduces the contact area between the first side surface 330 of the front stopper 300 and the guide column 530. The inclined surface 375 promotes stable displacement of the front stop 300 between the guide column 530 and the flange portion 540.
 第1側面330の傾斜面375を第1傾斜面と呼び、第2側面340の傾斜面345を第2傾斜面と呼び、若しくは、第1側面330の傾斜面375を第2傾斜面と呼び、第2側面340の傾斜面345を第1傾斜面と呼んでも構わない。幾つかの実施形態においては、第1傾斜面及び第2傾斜面はお互いに平行である。 The inclined surface 375 of the first side surface 330 is called a first inclined surface, the inclined surface 345 of the second side surface 340 is called a second inclined surface, or the inclined surface 375 of the first side surface 330 is called a second inclined surface, The inclined surface 345 of the second side surface 340 may be referred to as a first inclined surface. In some embodiments, the first inclined surface and the second inclined surface are parallel to each other.
 図4及び図7に示すように各前止め300は、ファスナーテープ100のテープ上面101から離間した上面350と、ファスナーテープ100のテープ下面102に面一の下面360を有する。芯紐155を挟んで、前止め300のテープ外方領域には段差部351が設けられ、そのテープ内方領域には下り傾斜面352が設けられる。段差部351は、ファスナーテープ100の側縁部150に沿って延び、またその延在過程において変化する左右幅W351を有する。下り傾斜面352は、第2側面340に接続するまでファスナーテープ100に向かって下り傾斜している。下り傾斜面352と段差部351の間には曲面353が設けられる。 As shown in FIGS. 4 and 7, each front stop 300 has an upper surface 350 spaced from the tape upper surface 101 of the fastener tape 100 and a lower surface 360 that is flush with the tape lower surface 102 of the fastener tape 100. A stepped portion 351 is provided in the tape outer region of the front stopper 300 with the core string 155 interposed therebetween, and a downward inclined surface 352 is provided in the tape inner region. The step portion 351 extends along the side edge 150 of the fastener tape 100 and has a left-right width W351 that changes in the extending process. The downward inclined surface 352 is inclined downward toward the fastener tape 100 until it is connected to the second side surface 340. A curved surface 353 is provided between the downward inclined surface 352 and the stepped portion 351.
 なお、前止め300のテープ内方領域及びテープ外方領域は相対的なものである。例えば、図示例の場合、前止め300のテープ内方領域が、前止め300の左右方向の中心よりもテープ内方にある領域である。前止め300のテープ外方領域が、前止め300の左右方向の中心よりもテープ外方にある領域である。前止め300の左右方向の中心から左右方向にややシフトした点に照らしてテープ内方及びテープ外方領域が規定され得る。 Note that the tape inner area and the tape outer area of the front stop 300 are relative. For example, in the illustrated example, the tape inner area of the front stop 300 is an area located inside the tape with respect to the center of the front stop 300 in the left-right direction. The tape outer region of the front stop 300 is a region located on the tape outer side than the center of the front stop 300 in the left-right direction. The tape inner area and the tape outer area can be defined in light of a point slightly shifted in the left-right direction from the center of the front stop 300 in the left-right direction.
 各前止め300の段差部351はスライダー500の構造との干渉を回避又は抑制するために設けられる。各前止め300の下り傾斜面352はスライダー500の構造との干渉を回避又は抑制するために設けられる。 The step portion 351 of each front stop 300 is provided in order to avoid or suppress interference with the structure of the slider 500. The downward inclined surface 352 of each front stop 300 is provided in order to avoid or suppress interference with the structure of the slider 500.
 図12に示すように、スライダー500の上翼板510及び下翼板520には左右のエレメントの移動路を区画するための仕切り壁570が設けられる。また、上翼板510とフランジ部540の連結箇所の内壁にはコイルエレメントの反転部234を押さえるための押さえ部580が設けられる。 As shown in FIG. 12, the upper wing plate 510 and the lower wing plate 520 of the slider 500 are provided with partition walls 570 for partitioning the movement paths of the left and right elements. In addition, a pressing portion 580 for pressing the reversing portion 234 of the coil element is provided on the inner wall of the connection portion between the upper blade plate 510 and the flange portion 540.
 上述の段差部351により前止め300のテープ外方領域が薄肉化され、これにより、上下に位置する仕切り壁570と前止め300の干渉が抑制される。前止め300には、ファスナーテープ100上に設けられていない肉薄部354が設けられている。 The tape outer area of the front stop 300 is thinned by the above-described stepped portion 351, and thereby the interference between the partition wall 570 positioned above and below and the front stop 300 is suppressed. The front stop 300 is provided with a thin portion 354 that is not provided on the fastener tape 100.
 図示例においては、肉薄部354は、前止め300のファスナーテープの側縁部150よりもテープ外方に位置する。肉薄部354は、最大厚H300の前止め300よりも段差部351の深さD351だけ薄い。段差部351の左右幅W351は、前後方向において変化する。図示例においては、前止め300の後方領域における段差部351の左右幅W351が、前止め300の前方領域における段差部351の左右幅W351の幅よりも大きい。この場合、前止め300の前方領域において芯紐155に対する前止め300の結合強度が好適に維持され、またよりスライダー500の内部へと入り込む前止め300の後方領域において仕切り壁570と前止め300の干渉を効果的に抑制することができる。上述の下り傾斜面352により押さえ部580と前止め300の干渉が抑制される。 In the example of illustration, the thin part 354 is located in the tape outer side rather than the side edge part 150 of the fastener tape of the front stop 300. FIG. The thin portion 354 is thinner than the front stop 300 having the maximum thickness H300 by the depth D351 of the step portion 351. The left-right width W351 of the stepped portion 351 changes in the front-rear direction. In the illustrated example, the left and right width W351 of the step portion 351 in the rear region of the front stop 300 is larger than the left and right width W351 of the step portion 351 in the front region of the front stop 300. In this case, the bonding strength of the front stopper 300 with respect to the core string 155 is suitably maintained in the front region of the front stopper 300, and the partition wall 570 and the front stopper 300 are further rearward in the region of the front stopper 300 that enters the slider 500 more. Interference can be effectively suppressed. The above-described downward inclined surface 352 suppresses interference between the pressing portion 580 and the front stop 300.
 本実施形態においては、各前止め300は、凸状係合部380と凹状係合部390の係合及び接触に起因して回動力が付与される。前止め300と仕切り壁570との干渉や前止め300と押さえ部580の干渉が生じると、この前止め300の回動が阻害されてしまうおそれがある。本実施形態においては、上述の段差部351及び下り傾斜面352を前止め300に設け、このような問題の顕在化を回避又は抑制する。 In the present embodiment, each front stop 300 is provided with a rotational force due to the engagement and contact between the convex engagement portion 380 and the concave engagement portion 390. If interference between the front stop 300 and the partition wall 570 or interference between the front stop 300 and the pressing portion 580 occurs, the rotation of the front stop 300 may be hindered. In the present embodiment, the above-described stepped portion 351 and the downward inclined surface 352 are provided in the front stop 300 to avoid or suppress the occurrence of such a problem.
 図示例においては、D351<H300/3を満足し、ここで、D351が段差部351の深さであり、H300が前止め300の最大厚である。換言すれば、段差部351の深さは、前止め300の最大厚の3分の1よりも小さい。 In the illustrated example, D351 <H300 / 3 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is smaller than one third of the maximum thickness of the front stop 300.
 図示例においては、D351<H300/4を満足し、ここで、D351が段差部351の深さであり、H300が前止め300の最大厚である。換言すれば、段差部351の深さは、前止め300の最大厚の4分の1よりも小さい。 In the illustrated example, D351 <H300 / 4 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is smaller than a quarter of the maximum thickness of the front stop 300.
 図示例においては、D351<H300/5を満足し、ここで、D351が段差部351の深さであり、H300が前止め300の最大厚である。換言すれば、段差部351の深さは、前止め300の最大厚の5分の1よりも小さい。 In the illustrated example, D351 <H300 / 5 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is smaller than one fifth of the maximum thickness of the front stop 300.
 図示例においては、D351>H300/6を満足し、ここで、D351が段差部351の深さであり、H300が前止め300の最大厚である。換言すれば、段差部351の深さは、前止め300の最大厚の6分の1よりも大きい。 In the illustrated example, D351> H300 / 6 is satisfied, where D351 is the depth of the stepped portion 351 and H300 is the maximum thickness of the front stop 300. In other words, the depth of the stepped portion 351 is larger than 1/6 of the maximum thickness of the front stop 300.
 図5及び図8に示すように、段差部351は、前止め300のテープ外方領域の前方及び後方領域に亘って設けられる。同様に、下り傾斜面352は、前止め300のテープ内方領域の前方及び後方領域に亘って設けられる。曲面353は、後方から前方に向かって左右幅が広がるように設けられる。スライダー500の仕切り壁570及び押さえ部580との干渉の回避又は抑制が十分に促進されることが予期される。図12及び図13の参照からこれらの構造により達成される効果が即時に理解されるだろう。 As shown in FIGS. 5 and 8, the stepped portion 351 is provided across the front and rear regions of the tape outer region of the front stop 300. Similarly, the downward inclined surface 352 is provided across the front and rear regions of the tape inner region of the front stop 300. The curved surface 353 is provided so that the lateral width is widened from the rear to the front. It is expected that avoidance or suppression of interference between the partition wall 570 and the pressing portion 580 of the slider 500 is sufficiently promoted. The effect achieved by these structures will be readily understood from the reference to FIGS.
 図9乃至図11を参照してスライダー500を前進させ、左右一対のファスナーストリンガー400を閉じ、左右一対のファスナーエレメント200を噛み合わせ、スライダー500内に左右一対の前止め300を収容する過程について説明する。ここで、左右一対のファスナーストリンガー400において、左側ファスナーストリンガー400の左側前止め300は、右側ファスナーストリンガー400の右側前止め300よりもファスナーテープ100の側縁部150に沿って長く延びる。また、左側前止め300の第1側面330の後方領域には凹状係合部390が設けられ、右側前止め300の第1側面330の後方領域には凸状係合部380が設けられる。 The process of moving the slider 500 forward, closing the pair of left and right fastener stringers 400, engaging the pair of left and right fastener elements 200, and housing the pair of left and right front stops 300 in the slider 500 will be described with reference to FIGS. To do. Here, in the pair of left and right fastener stringers 400, the left front stopper 300 of the left fastener stringer 400 extends longer along the side edge 150 of the fastener tape 100 than the right front stopper 300 of the right fastener stringer 400. Further, a concave engagement portion 390 is provided in the rear region of the first side surface 330 of the left front stop 300, and a convex engagement portion 380 is provided in the rear region of the first side surface 330 of the right front stop 300.
 図9に示すスライダー位置から図10に示すスライダー位置にスライダー500を前進させる過程において、左右の各ファスナーエレメント200の係合部210がスライダー500の案内柱530の側面上を摺動し、また基部220がスライダー500のフランジ部540の内側面上を摺動する。図9から理解できるように、右側前止め300よりも左側前止め300が先にスライダー500の案内柱530とフランジ部540の間の開口に突入する。なお、スライダー500は、案内柱530と左側フランジ部540の間に左側開口を有し、案内柱530と右側フランジ部540の間に右側開口を有する。 In the process of moving the slider 500 forward from the slider position shown in FIG. 9 to the slider position shown in FIG. 10, the engaging portion 210 of each of the left and right fastener elements 200 slides on the side surface of the guide column 530 of the slider 500, and the base portion. 220 slides on the inner surface of the flange portion 540 of the slider 500. As can be understood from FIG. 9, the left front stop 300 enters the opening between the guide column 530 and the flange portion 540 of the slider 500 before the right front stop 300. The slider 500 has a left opening between the guide column 530 and the left flange portion 540, and a right opening between the guide column 530 and the right flange portion 540.
 図10に示すスライダー位置から図11に示すスライダー位置にスライダー500を前進させる過程で、スライダー500の右側開口からスライダー500内へ突入した右側前止め300の凸状係合部380がスライダー500の左右方向の中心線CLを越えて左側前止め300の凹状係合部390に接触し、これにより、左側前止め300に時計方向の回転が生じ、右側前止め300には反時計方向の回転が生じる。この時、左側開口からスライダー500内へ突入した左側前止め300の突出部373は、スライダー500の左右方向の中心線CLを越えて右側前止め300の後面320の後方に位置する。左右の各前止め300には上述のように傾斜面345が設けられており、各前止め300の適当量の回転が許容される。各前止め300の傾斜面345とスライダー500のフランジ部540の内壁面の間の間隔SP5が、各前止め300の回転により減じられ、図2に示した間隔W110が減じられる。 In the process of moving the slider 500 forward from the slider position shown in FIG. 10 to the slider position shown in FIG. 11, the convex engagement portion 380 of the right front stop 300 that has entered the slider 500 from the right opening of the slider 500 Crosses the center line CL in the direction and contacts the concave engaging portion 390 of the left front stop 300, thereby causing the left front stop 300 to rotate clockwise and the right front stop 300 to rotate counterclockwise. . At this time, the protrusion 373 of the left front stop 300 that has entered the slider 500 from the left opening is positioned behind the rear surface 320 of the right front stop 300 beyond the center line CL in the left-right direction of the slider 500. The left and right front stops 300 are provided with the inclined surfaces 345 as described above, and an appropriate amount of rotation of each front stop 300 is allowed. The interval SP5 between the inclined surface 345 of each front stop 300 and the inner wall surface of the flange portion 540 of the slider 500 is reduced by the rotation of each front stop 300, and the interval W110 shown in FIG. 2 is reduced.
 一実施形態においては、各前止め300の傾斜面345がスライダー500のフランジ部540の内壁面に衝突するタイミングが、各前止め300の隆起部372が案内柱530に衝突するタイミングよりも早い。他の実施形態においては、各前止め300の傾斜面345がスライダー500のフランジ部540の内壁面に衝突するタイミングが、各前止め300の隆起部372が案内柱530に衝突するタイミングよりも遅い。更に他の実施形態においては、各前止め300の傾斜面345がスライダー500のフランジ部540の内壁面に衝突するタイミングが、各前止め300の隆起部372が案内柱530に衝突するタイミングと実質的に同一タイミングである。 In one embodiment, the timing at which the inclined surface 345 of each front stop 300 collides with the inner wall surface of the flange portion 540 of the slider 500 is earlier than the timing at which the raised portion 372 of each front stop 300 collides with the guide column 530. In another embodiment, the timing at which the inclined surface 345 of each front stop 300 collides with the inner wall surface of the flange portion 540 of the slider 500 is later than the timing at which the raised portion 372 of each front stop 300 collides with the guide column 530. . In still another embodiment, the timing at which the inclined surface 345 of each front stop 300 collides with the inner wall surface of the flange portion 540 of the slider 500 is substantially the same as the timing at which the raised portion 372 of each front stop 300 collides with the guide column 530. Are the same timing.
