Description

スライドファスナーSlide fastener
　本発明は、ファスナーエレメント列の一端部に上止が取り付けられたスライドファスナーに関する。 The present invention relates to a slide fastener in which a top stopper is attached to one end of a fastener element row.
　従来、スライドファスナーにおいて、ファスナーテープの対向側縁に沿って取り付けられたファスナーエレメント列の上端部に合成樹脂製の上止が射出成形されたスライドファスナーが知られている（特許文献１参照）。 Conventionally, a slide fastener in which a top end made of a synthetic resin is injection-molded at an upper end portion of a fastener element row attached along the opposite side edge of a fastener tape is known (see Patent Document 1).
　この上止は、ファスナーテープの表面側にある表面部およびファスナーテープの裏面側にある裏面部とを有しているとともに、ファスナーテープの対向側縁を跨いで形成されているので、例えば裏面がない上止と比べて、ファスナーテープから剥れにくい構成となっている。 The top stop has a front surface portion on the front surface side of the fastener tape and a back surface portion on the back surface side of the fastener tape, and is formed across the opposite side edge of the fastener tape. Compared to no top stopper, it is more difficult to peel off from the fastener tape.
　また、上止は、スライダーを抜け止めするストッパーとして機能する構成を備えている。具体的には、スライドファスナーの左右方向においてファスナーエレメントの噛合頭部側に位置する上止の外側面には、左右方向外側に膨出した膨出部が形成されており、左右方向において前記外側面とは反対側に位置する内側面には、左右方向内側に突出した突部が形成されている。
　この上止では、スライドファスナーのスライダーがスライドしてファスナーエレメント列の上端部に配置された場合、上止の膨出部がスライダーの胴体の左右方向における中間位置に形成された案内柱に当接し、かつ、上止の突部がスライダーの胴体の左右のフランジに当接することで、スライダーのスライドを規制する。 The top stopper has a structure that functions as a stopper for preventing the slider from coming off. Specifically, a bulging portion bulging outward in the left-right direction is formed on the outer surface of the top stop located on the side of the engagement head of the fastener element in the left-right direction of the slide fastener. A protrusion projecting inward in the left-right direction is formed on the inner surface located on the side opposite to the side surface.
In this top stopper, when the slider of the slide fastener slides and is arranged at the upper end portion of the fastener element row, the bulging portion of the top stopper abuts on a guide column formed at an intermediate position in the left-right direction of the body of the slider. In addition, the slide of the slider is regulated by the protrusions of the top stop coming into contact with the left and right flanges of the slider body.

　ところで、特許文献１に記載のスライドファスナーでは、その上止が、ファスナーテープから剥れにくくするための裏面部と、前述した膨出部および突出部などのストッパーとして機能する構成とを別部分の構成として有しているので、上止が大きくなりがちであった。 By the way, in the slide fastener described in Patent Document 1, the upper end of the rear surface portion for making it difficult to peel off from the fastener tape and the structure functioning as a stopper such as the bulging portion and the protruding portion described above are different parts. Since it has as a structure, the top end tended to be large.
　本発明の目的は、ファスナーテープから剥れにくく、かつストッパーとして機能する上止を従来よりも小さくすることができるスライドファスナーを提供することにある。 An object of the present invention is to provide a slide fastener that is less likely to be peeled off from a fastener tape and that can make an upper stopper that functions as a stopper smaller than a conventional stopper.
　本発明のスライドファスナーは、ファスナーテープおよび前記ファスナーテープの側縁部に沿ったファスナーエレメント列を有した一対のファスナーストリンガーと、前記各ファスナーエレメント列に連結されるスライダーとを備え、前記各ファスナーエレメント列の一端部に上止がそれぞれ配置されたスライドファスナーであって、前記上止は、上止表面部と、前記上止表面部に連続した上止裏面部を有し、前記上止表面部は、前記ファスナーテープの表面に付着され、前記上止裏面部は、前記ファスナーテープの裏面に付着され、前記上止裏面部は、前記スライダーのスライド方向において前記スライダーに当接可能に対向して配置されることを特徴とする。 The slide fastener of the present invention includes a pair of fastener stringers having a fastener tape and a fastener element row along a side edge of the fastener tape, and a slider connected to each fastener element row, and each fastener element A slide fastener in which top stoppers are respectively arranged at one end of a row, wherein the top stopper has a top stopper surface portion and a top stopper back surface portion continuous with the top stopper surface portion, and the top stopper surface portion. Is attached to the front surface of the fastener tape, the top stop back surface portion is attached to the back surface of the fastener tape, and the top stop back surface portion is opposed to the slider in a sliding direction of the slider. It is characterized by being arranged.
　本発明のスライドファスナーによれば、上止が、ファスナーテープの表面および裏面に付着された上止表面部および上止裏面部を有しているので、例えば上止裏面部がない上止と比べて、上止をファスナーテープから剥れにくい構成にできる。また、スライダーがスライドしてファスナーエレメント列の一端部に配置される場合には、スライド方向においてスライダーに対向して配置された上止裏面部が当該スライダーに当接するので、当該スライダーのスライドを規制できる。このように、上止裏面部の構成によって、ファスナーテープから剥れにくくでき、かつストッパーとして機能させることができるので、ファスナーテープから剥れにくくする構成とストッパーとして機能する構成とを別部分で構成する必要がなくなり、上止を小さくすることができる。 According to the slide fastener of the present invention, since the top stopper has the top stopper surface portion and the top stopper back surface portion attached to the front and back surfaces of the fastener tape, for example, compared with the stopper having no top stopper back surface portion. Thus, the top stopper can be made difficult to peel off from the fastener tape. In addition, when the slider slides and is arranged at one end of the fastener element row, the top back surface portion arranged to face the slider in the sliding direction comes into contact with the slider, so that the sliding of the slider is restricted. it can. In this way, the configuration of the top stop back surface part makes it difficult to peel off from the fastener tape and can function as a stopper. There is no need to do so, and the top stop can be made smaller.
　本発明のスライドファスナーでは、前記上止表面部は、前記ファスナーエレメント列の一端部を構成するエレメントが埋め込まれた保持部と、前記上止の厚さ方向において前記上止裏面部と対向した対向部とを有し、前記保持部および前記対向部は、前記スライド方向において異なる位置に配置されていることが好ましい。
　このような構成によれば、スライド方向において保持部と異なる位置に配置された対向部の裏側に上止裏面部が対向して配置されるので、エレメントが埋め込まれた保持部よりもファスナーテープから剥れやすい対向部を上止裏面部によって補強でき、この対向部がファスナーテープから剥れることを抑制できる。 In the slide fastener of the present invention, the top stop surface portion is opposed to the holding portion in which an element constituting one end portion of the fastener element row is embedded and opposed to the top stop back surface portion in the thickness direction of the top stop. It is preferable that the holding part and the opposing part are arranged at different positions in the sliding direction.
According to such a configuration, the top back surface portion is disposed opposite to the back side of the facing portion that is disposed at a position different from the holding portion in the sliding direction, so that the fastener tape can be separated from the holding portion in which the element is embedded. The facing part that is easily peeled off can be reinforced by the top back surface part, and the facing part can be prevented from peeling off from the fastener tape.
　本発明のスライドファスナーでは、前記対向部は、前記スライド方向において前記保持部よりも前方に配置されていることが好ましい。
　このような構成によれば、スライダーが上止裏面部に当接した状態で上止表面部のうち対向部よりも前記スライド方向において後方に位置する部分をスライダー内に収めることができる。 In the slide fastener according to the aspect of the invention, it is preferable that the facing portion is disposed ahead of the holding portion in the sliding direction.
According to such a configuration, a portion of the top stop surface portion that is located rearward in the sliding direction with respect to the facing portion can be accommodated in the slider in a state where the slider is in contact with the top stop back surface portion.
　本発明のスライドファスナーでは、前記ファスナーテープの表面のうち前記保持部が付着された部分に対向する裏面の部分は、露呈していることが好ましい。
　このような構成によれば、エレメントが埋め込まれてファスナーテープから剥れにくい箇所である保持部の裏側から上止裏面部をなくすことができ、上止を小型化できる。 In the slide fastener of the present invention, it is preferable that a portion of the back surface facing the portion to which the holding portion is attached is exposed in the surface of the fastener tape.
According to such a configuration, the top stopper back surface portion can be eliminated from the back side of the holding portion, which is a place where the element is embedded and is difficult to peel off from the fastener tape, and the top stopper can be downsized.
　本発明のスライドファスナーでは、前記上止表面部は、前記ファスナーテープの幅方向外側に配置された外側面と、前記ファスナーテープの幅方向内側に配置された内側面とを有し、前記上止裏面部は、前記上止表面部の外側面側から前記上止表面部の内側面側に向かって延出して形成され、前記上止裏面部の先端は、前記上止の厚さ方向において前記上止表面部の内側面に沿った位置に配置されていることが好ましい。
　このような構成によれば、上止裏面部の先端が、上止の厚さ方向において上止表面部の内側面に沿った位置に配置されているので、ファスナーテープの幅方向において上止表面部および上止裏面部のうちの一方が他方に対して突出した部分が形成されなくなる。このように突出した部分を形成しないので、当該突出した部分に付着されたファスナーテープの部分が上止表面部および上止裏面部の他方に支えられずに剥れてしまうことがなくなる。 In the slide fastener of the present invention, the top surface portion includes an outer surface disposed on the outer side in the width direction of the fastener tape, and an inner side surface disposed on the inner side in the width direction of the fastener tape, The back surface portion is formed to extend from the outer surface side of the top stopper surface portion toward the inner surface side of the top stopper surface portion, and the tip of the top stopper back surface portion is formed in the thickness direction of the top stopper. It is preferable to arrange at a position along the inner surface of the top stop surface portion.
According to such a configuration, since the tip of the top stopper back surface portion is disposed at a position along the inner surface of the top stopper surface portion in the thickness direction of the stopper, the top stopper surface in the width direction of the fastener tape. A portion in which one of the portion and the top back surface portion protrudes from the other is not formed. Since the protruding portion is not formed in this manner, the portion of the fastener tape attached to the protruding portion is not peeled off without being supported by the other of the top stop surface portion and the top stop back surface portion.
　本発明のスライドファスナーでは、前記上止裏面部は、その基端側から前記先端側に向かうに従って幅が広くなっていることが好ましい。
　このような構成によれば、上止裏面部の先端側は、上止表面部と連続している基端側から離間しているため、上止裏面部の基端側と比べてファスナーテープからの剥れにくさが低下するが、上止裏面部の先端側における幅寸法を大きくしてファスナーテープに対する付着面積を広げることで、上止裏面部の先端側の部分をファスナーテープから剥れにくくできる。 In the slide fastener of the present invention, it is preferable that the upper back surface portion has a width that increases from the proximal end side toward the distal end side.
According to such a configuration, the distal end side of the top stop back surface portion is separated from the base end side continuous with the top stop surface portion, and therefore, from the fastener tape compared to the base end side of the top stop back surface portion. Although it is difficult to peel off, the width of the top end of the top stop back surface is increased to increase the adhesion area to the fastener tape, making it difficult for the top stop back portion to peel off from the fastener tape. it can.
　本発明のスライドファスナーでは、前記上止裏面部は、その基端側から前記先端側に向かうに従って前記スライド方向において後方に位置する形状となっていることが好ましい。
　このような構成によれば、スライダーがスライドファスナーを閉めるスライド方向に移動され、前記上止裏面部に当接すると、各上止には、そのスライド方向前方側がファスナーテープの幅方向内側に向かうとともに、そのスライド方向後方側がファスナーテープの幅方向外側に向かう回転力が生じて、上止のスライド方向後方側同士でスライダーの案内柱部４１３を挟み込むので、スライダーのガタツキを抑制できる。 In the slide fastener of the present invention, it is preferable that the upper back surface portion has a shape that is located rearward in the sliding direction as it goes from the proximal end side to the distal end side.
According to such a configuration, when the slider is moved in the sliding direction for closing the slide fastener and abuts on the upper back surface portion, each upper stop has its front side in the sliding direction directed inward in the width direction of the fastener tape. Further, a rotational force is generated on the rear side in the slide direction toward the outer side in the width direction of the fastener tape, and the guide column part 413 of the slider is sandwiched between the rear sides in the slide direction of the top stopper, so that rattling of the slider can be suppressed.
　本発明のスライドファスナーでは、前記スライダーは、前記各ファスナーエレメント列の裏面側に配置される下板部を有し、前記上止裏面部は、前記スライド方向において前記下板部の上面に当接可能に対向したストッパー面を有し、前記ストッパー面は、前記下板部の上面に沿った形状とされていることが好ましい。
　このような構成によれば、ストッパー面がスライダーの下板部の上面に沿った形状とされているので、ストッパー面の全面を下板部の上面に当接させることができる。このため、スライダーが上止に当たる際の衝撃をストッパー面の全面に分散させることができ、前記ストッパー面の破損などのおそれを低減できる。 In the slide fastener of the present invention, the slider has a lower plate portion disposed on the back surface side of each fastener element row, and the upper back surface portion contacts the upper surface of the lower plate portion in the slide direction. It is preferable to have a stopper surface that faces each other, and the stopper surface has a shape along the upper surface of the lower plate portion.
According to such a configuration, since the stopper surface is shaped along the upper surface of the lower plate portion of the slider, the entire surface of the stopper surface can be brought into contact with the upper surface of the lower plate portion. For this reason, it is possible to disperse the impact when the slider hits the upper end over the entire surface of the stopper surface, thereby reducing the possibility of damage to the stopper surface.
　本発明のスライドファスナーでは、前記スライダーは、前記各ファスナーエレメント列の表面側に配置される上板部と、前記各ファスナーエレメント列の裏面側に配置される下板部と、前記上板部および前記下板部をつないだ案内柱部とを有し、前記上止表面部の表外面から前記ファスナーテープの裏面までの寸法を寸法Ａとし、前記上止表面部の表外面から前記上止裏面部の裏外面までの寸法を寸法Ｂとし、前記上板部の内面から前記下板部の内面までの寸法を寸法Ｃとした場合、寸法関係はＡ＜Ｃ＜Ｂであることが好ましい。
　このような構成によれば、スライダーがファスナーエレメント列の一端部に配置された場合には、上止表面部をスライダーの上板部および下板部間に挿入できるとともに、上止裏面部をスライダーの下板部に当接させて当該スライダーを抜け止めできる。 In the slide fastener of the present invention, the slider includes an upper plate portion disposed on the front surface side of each fastener element row, a lower plate portion disposed on the back surface side of each fastener element row, the upper plate portion, A guide column portion that connects the lower plate portion, and a dimension from the outer surface of the upper stopper surface portion to the rear surface of the fastener tape is dimension A, and from the outer surface of the upper stopper surface portion to the upper stopper rear surface. When the dimension from the inner surface of the upper plate part to the inner surface of the lower plate part is dimension C, the dimensional relationship is preferably A <C <B.
According to such a configuration, when the slider is arranged at one end portion of the fastener element row, the upper stopper surface portion can be inserted between the upper plate portion and the lower plate portion of the slider, and the upper stopper rear surface portion is the slider. The slider can be prevented from coming off by contacting the lower plate portion.
　本発明のスライドファスナーでは、前記上止表面部の外側面は、前記ファスナーテープの幅方向外側に膨出した膨出部を有していることが好ましい。
　このような構成によれば、スライドファスナーの閉鎖状態では、上止の膨出部と案内柱部との隙間を狭め、また、膨出部を案内柱部に当接させることができ、これにより、ファスナーテープの幅方向におけるスライダーのガタツキを抑制できる。
　さらに、上止表面部および上止裏面部の連続部分も膨出部を含むので、当該連続部分を大きくできて上止の強度を高めることができる。 In the slide fastener of the present invention, it is preferable that the outer surface of the top stop surface portion has a bulging portion that bulges outward in the width direction of the fastener tape.
According to such a configuration, in the closed state of the slide fastener, the gap between the bulging portion of the top stop and the guide column portion can be narrowed, and the bulging portion can be brought into contact with the guide column portion. Further, rattling of the slider in the width direction of the fastener tape can be suppressed.

　図８に示すように挿通溝４５Ａ，４５Ｂに上止２６，３６がそれぞれ挿入された状態では、案内柱部４１３と上止２６，３６との隙間は膨出部２６４Ａ，３６４Ａによって狭められている。なお、膨出部２６４Ａ，３６４Ａは案内柱部４１３に当接していてもよい。これにより、スライダー４の左右方向におけるガタツキは抑制される。 As shown in FIG. 8, the guide column portion 413 is formed at an intermediate position in the left-right direction in FIG. 8, which is an upper portion between the upper plate portion 411 and the lower plate portion 412. The guide post 413 divides the insertion groove 45 into a left insertion groove 45A in FIG. 8 through which the fastener element row 24 is inserted and a right insertion groove 45B in FIG. 8 through which the fastener element row 34 is inserted.
As shown in FIG. 8, in the state in which the top stoppers 26 and 36 are inserted into the insertion grooves 45A and 45B, the gap between the guide column part 413 and the top stoppers 26 and 36 is narrowed by the bulging parts 264A and 364A. . Note that the bulging portions 264A and 364A may be in contact with the guide column portion 413. Thereby, the rattling of the slider 4 in the left-right direction is suppressed.
　図９に示すように、上止表面部２６１の表外面２６２からファスナーテープ２１の裏面２１ＢまでのＺ方向における寸法（保持部２６８の表外面からファスナーテープ２１の裏面２１Ｂまでの寸法）を寸法Ａとし、上止表面部２６１の表外面２６２から上止裏面部２７１の裏外面２７７までのＺ方向における寸法（対向部２６９の表外面から上止裏面部２７１の裏外面までの寸法）を寸法Ｂとし、上板部４１１の内面４１１Ｂから下板部４１２の内面４１２ＢまでのＺ方向における寸法を寸法Ｃとした場合、寸法関係はＡ＜Ｃ＜Ｂである。 As shown in FIG. 9, the dimension in the Z direction from the front outer surface 262 of the top stop surface portion 261 to the rear surface 21B of the fastener tape 21 (dimension from the front outer surface of the holding portion 268 to the rear surface 21B of the fastener tape 21) is dimension A. Dimension B in the Z direction from the front outer surface 262 of the top stop surface portion 261 to the back outer surface 277 of the top stop back surface portion 271 (dimension from the front outer surface of the facing portion 269 to the back outer surface of the top stop back surface portion 271) is dimension B. When the dimension in the Z direction from the inner surface 411B of the upper plate portion 411 to the inner surface 412B of the lower plate portion 412 is defined as C, the dimensional relationship is A <C <B.
　また、上止表面部２６１の表外面２６２からファスナーテープ２１の表面２１ＡまでのＺ方向における寸法（保持部２６８の表外面からファスナーテープ２１の表面２１Ａまでの寸法）を寸法Ａ１とし、上止表面部２６１の表外面２６２からファスナーテープ２１の表面２１ＡまでのＺ方向における寸法（対向部２６９の表外面からファスナーテープ２１の表面２１Ａまでの寸法）を寸法Ｂ１とし、上板部４１１の内面４１１Ｂからファスナーテープ２１の表面２１ＡまでのＺ方向における寸法を寸法Ｃ１とした場合、寸法関係はＡ１＝Ｂ１＜Ｃ１である（なお、Ｂ１＜Ａ１＜Ｃ１であってもよい）。 Further, the dimension in the Z direction from the front outer surface 262 of the top stop surface part 261 to the surface 21A of the fastener tape 21 (the dimension from the front outer surface of the holding part 268 to the surface 21A of the fastener tape 21) is defined as dimension A1, and the top stop surface The dimension in the Z direction from the outer surface 262 of the part 261 to the surface 21A of the fastener tape 21 (the dimension from the outer surface of the facing part 269 to the surface 21A of the fastener tape 21) is defined as dimension B1, and from the inner surface 411B of the upper plate part 411 When the dimension in the Z direction to the surface 21A of the fastener tape 21 is defined as the dimension C1, the dimensional relationship is A1 = B1 <C1 (B1 <A1 <C1 may be satisfied).
　さらに、上止裏面部２７１の裏外面２７７からファスナーテープ２１の裏面２１ＢまでのＺ方向における寸法を寸法Ｂ２とし、下板部４１２の内面４１２Ｂからファスナーテープ２１の裏面２１ＢまでのＺ方向における寸法を寸法Ｃ２とした場合、寸法関係は、Ｃ２＜Ｂ２である。 Further, the dimension in the Z direction from the back outer surface 277 of the top back surface portion 271 to the back surface 21B of the fastener tape 21 is defined as dimension B2, and the dimension in the Z direction from the inner surface 412B of the lower plate portion 412 to the back surface 21B of the fastener tape 21 is defined as dimension B2. When the dimension is C2, the dimensional relationship is C2 <B2.
　なお、上止２６の厚さ方向において保持部２６８（図４参照）に対向する裏面側の部分には後述する変形例におけるスライダー挿入部がないため、当該部分における上止裏面部の厚さ寸法Ａ２は「０」である。また、スライダー挿入部がある場合、寸法関係はＡ２＜Ｃ２＜Ｂ２とされる。 In addition, since there is no slider insertion part in the modification mentioned later in the part of the back surface facing the holding | maintenance part 268 (refer FIG. 4) in the thickness direction of the top stop 26, the thickness dimension of the top stop back surface part in the said part A2 is “0”. When there is a slider insertion portion, the dimensional relationship is A2 <C2 <B2.
　このため、上止裏面部２７１（３７１）は、スライダー４のスライド方向において当該スライダー４の下板部４１２の上面４１２Ｃに当接可能に対向し、配置される。
　このように寸法関係が設定されているので、上止２６の上止表面部２６１は、挿通溝４５Ａに挿入され、上止裏面部２７１のストッパー面２７６は、下板部４１２の上面４１２Ｃに当接する。また、前述同様に、上止３６の上止表面部３６１は、挿通溝４５Ｂに挿入され、上止裏面部３７１のストッパー面３７６は、下板部４１２の上面４１２Ｃに当接する。これらの当接部によってスライダー４が上止２６，３６よりもスライド方向前方へのスライドが規制され、この規制によってスライダー４が抜け止めされる。 For this reason, the upper back surface portion 271 (371) is disposed so as to oppose the upper surface 412C of the lower plate portion 412 of the slider 4 in the sliding direction of the slider 4.
Since the dimensional relationship is set in this way, the top surface 261 of the top stop 26 is inserted into the insertion groove 45A, and the stopper surface 276 of the top back surface portion 271 contacts the top surface 412C of the bottom plate portion 412. Touch. Similarly to the above, the top surface portion 361 of the top stop 36 is inserted into the insertion groove 45B, and the stopper surface 376 of the top back surface portion 371 contacts the top surface 412C of the bottom plate portion 412. These abutting portions restrict the slider 4 from sliding forward in the sliding direction with respect to the top stops 26 and 36, and the slider 4 is prevented from coming off by this restriction.
［本実施形態の効果］
（１）前記実施形態では、スライドファスナー１は、ファスナーテープ２１，３１およびファスナーテープ２１，３１の側縁部２２，３２に沿ったファスナーエレメント列２４，３４を有した一対のファスナーストリンガー２，３と、各ファスナーエレメント列２４，３４に連結されるスライダー４とを備え、各ファスナーエレメント列２４，３４の上端部２４Ａ，３４Ａに上止２６，３６がそれぞれ配置されたスライドファスナー１であって、上止２６，３６は、上止表面部２６１，３６１と、上止表面部２６１，３６１に連続した上止裏面部２７１，３７１を有し、上止表面部２６１，３６１は、ファスナーテープ２１，３１の表面２１Ａ，３１Ａに付着され、上止裏面部２７１，３７１は、ファスナーテープ２１，３１の裏面２１Ｂ，３１Ｂに付着され、上止裏面部２７１，３７１は、スライダー４のスライド方向において当該スライダー４に当接可能に対向し、配置されることを特徴とする。
　上記構成を有するため、上止２６，３６が、ファスナーテープ２１，３１の表面２１Ａ，３１Ａおよび裏面２１Ｂ，３１Ｂに付着された上止表面部２６１，３６１および上止裏面部２７１，３７１を有しているので、例えば上止裏面部２７１，３７１がない上止と比べて、上止２６，３６をファスナーテープ２１，３１から剥れにくい構成にできる。また、スライダー４がスライドしてファスナーエレメント列２４，３４の上端部２４Ａ，３４Ａに配置される場合には、スライド方向においてスライダー４に対向して配置された上止裏面部２７１，３７１が当該スライダー４に当接するので、当該スライダー４のスライドを規制できる。このように、上止裏面部２７１，３７１の構成によって、ファスナーテープ２１，３１から剥れにくくでき、かつストッパーとして機能させることができるので、ファスナーテープ２１，３１から剥れにくくする構成とストッパーとして機能する構成とを別部分で構成する必要がなくなり、上止２６，３６を小さくすることができる。 [Effect of this embodiment]
(1) In the above embodiment, the slide fastener 1 includes a pair of fastener stringers 2 and 3 having fastener element rows 24 and 34 along the side edges 22 and 32 of the fastener tapes 21 and 31 and the fastener tapes 21 and 31. And a slider 4 connected to each fastener element row 24, 34, and a slide fastener 1 in which top stoppers 26, 36 are respectively arranged on upper end portions 24A, 34A of each fastener element row 24, 34, The top stoppers 26 and 36 have top stopper surface portions 261 and 361 and upper stopper rear surface portions 271 and 371 continuous with the upper stopper surface portions 261 and 361, respectively. 31 are attached to the front surfaces 21A and 31A of the upper end 31 and the upper back surfaces 271 and 371 are attached to the rear surfaces 21B and 21B of the fastener tapes 21 and 31, respectively. Attached to 1B, the top end stop back surface 271,371 is capable of abutting to and facing the slider 4 in the sliding direction of the slider 4, characterized in that it is arranged.
Since it has the above configuration, the top stoppers 26 and 36 have top stopper surface portions 261 and 361 and top stopper rear surface portions 271 and 371 attached to the front surfaces 21A and 31A and the rear surfaces 21B and 31B of the fastener tapes 21 and 31, respectively. Therefore, for example, the top stoppers 26 and 36 can be made difficult to peel off from the fastener tapes 21 and 31 as compared with the top stopper without the top stopper back surface portions 271 and 371. Further, when the slider 4 slides and is disposed at the upper end portions 24A and 34A of the fastener element rows 24 and 34, the upper back surface portions 271 and 371 disposed to face the slider 4 in the sliding direction are the sliders. 4, the sliding of the slider 4 can be regulated. As described above, the configuration of the top back surfaces 271 and 371 can be prevented from peeling off from the fastener tapes 21 and 31 and can function as a stopper. It is not necessary to configure the functioning structure separately, and the top stoppers 26 and 36 can be made small.
（２）上止表面部２６１，３６１は、ファスナーエレメント列２４，３４の上端部２４Ａ，３４Ａを構成する線条ファスナーエレメント２５，３５が埋め込まれた保持部２６８，３６８と、上止２６，３６の厚さ方向において上止裏面部２７１，３７１と対向した対向部２６９，３６９とを有し、保持部２６８，３６８および対向部２６９，３６９は、スライド方向において異なる位置に配置されている。
　このため、スライド方向において保持部２６８，３６８と異なる位置に配置された対向部２６９，３６９の裏側に上止裏面部２７１，３７１が対向して配置されるので、線条ファスナーエレメント２５，３５が埋め込まれた保持部２６８，３６８よりもファスナーテープ２１，３１から剥れやすい対向部２６９，３６９を上止裏面部２７１，３７１によって補強でき、対向部２６９，３６９がファスナーテープ２１，３１から剥れることを抑制できる。 (2) The top stopper surface portions 261 and 361 include holding portions 268 and 368 in which the linear fastener elements 25 and 35 constituting the upper end portions 24A and 34A of the fastener element rows 24 and 34 are embedded, and the top stoppers 26 and 36, respectively. The holding portions 268 and 368 and the opposing portions 269 and 369 are arranged at different positions in the sliding direction. The opposing portions 269 and 369 are opposed to the top stop back surface portions 271 and 371 in the thickness direction.
For this reason, since the top stop back surface portions 271 and 371 are disposed opposite to the back sides of the facing portions 269 and 369 disposed at positions different from the holding portions 268 and 368 in the sliding direction, the linear fastener elements 25 and 35 are The facing portions 269 and 369 that are more easily peeled off from the fastener tapes 21 and 31 than the embedded holding portions 268 and 368 can be reinforced by the top stop back surface portions 271 and 371, and the facing portions 269 and 369 are peeled off from the fastener tapes 21 and 31. This can be suppressed.
（３）対向部２６９，３６９は、スライダー４のスライド方向において保持部２６８，３６８よりも前方に配置されている。
　このため、スライダー４が上止裏面部２７１，３７１に当接した状態で上止表面部２６１，３６１のうち対向部２６９，３６９よりも、スライダー４のスライド方向において後方に位置する部分をスライダー４内に収めることができる。 (3) The facing portions 269 and 369 are disposed in front of the holding portions 268 and 368 in the sliding direction of the slider 4.
For this reason, a portion of the top stop surface portions 261 and 361 located behind the opposing portions 269 and 369 in the sliding direction of the slider 4 with the slider 4 in contact with the top stop back surface portions 271 and 371 is the slider 4. Can fit inside.
（４）ファスナーテープ２１，３１の表面２１Ａ，３１Ａのうち保持部２６８，３６８が付着された部分に対向する裏面２１Ｂ，３１Ｂの部分は、露呈している。
　このため、線条ファスナーエレメント２５，３５が埋め込まれてファスナーテープ２１，３１から剥れにくい箇所である保持部２６８，３６８の裏側から上止裏面部２７１，３７１をなくすことができ、上止２６，３６を小型化できる。 (4) Of the front surfaces 21A and 31A of the fastener tapes 21 and 31, the back surface portions 21B and 31B that face the portions to which the holding portions 268 and 368 are attached are exposed.
For this reason, the top stopper back surfaces 271 and 371 can be eliminated from the back side of the holding portions 268 and 368, which are portions where the linear fastener elements 25 and 35 are embedded and are not easily peeled off from the fastener tapes 21 and 31, and the top stopper 26 36 can be reduced in size.
（５）上止表面部２６１，３６１は、ファスナーテープ２１，３１の幅方向外側に配置された外側面２６４，３６４と、ファスナーテープ２１，３１の幅方向内側に配置された内側面２６５，３６５とを有し、上止裏面部２７１，３７１は、上止表面部２６１，３６１の外側面２６４，３６４側から上止表面部２６１，３６１の内側面２６５，３６５側に向かって延出して形成され、上止裏面部２７１，３７１の先端２７５，３７５は、上止２６，３６の厚さ方向において上止表面部２６１，３６１の内側面２６５，３６５に沿った位置に配置されている。
　このため、上止裏面部２７１，３７１の先端２７５，３７５が、上止２６，３６の厚さ方向において上止表面部２６１，３６１の内側面２６５，３６５に沿った位置に配置されているので、ファスナーテープ２１，３１の幅方向において上止表面部２６１，３６１および上止裏面部２７１，３７１のうちの一方が他方に対して突出した部分が形成されなくなる。このように突出した部分を形成しないので、当該突出した部分に付着されたファスナーテープ２１，３１の部分が上止表面部２６１，３６１および上止裏面部２７１，３７１の他方に支えられずに剥れてしまうことがなくなる。 (5) The top stop surface portions 261 and 361 include outer side surfaces 264 and 364 disposed on the outer side in the width direction of the fastener tapes 21 and 31, and inner side surfaces 265 and 365 disposed on the inner side in the width direction of the fastener tapes 21 and 31. The top stop back surface portions 271 and 371 are formed by extending from the outer side surfaces 264 and 364 side of the top stop surface portions 261 and 361 toward the inner side surfaces 265 and 365 side of the top stop surface portions 261 and 361. The top ends 275 and 375 of the top stopper back surfaces 271 and 371 are arranged along the inner side surfaces 265 and 365 of the top stopper surface portions 261 and 361 in the thickness direction of the top stoppers 26 and 36.
Therefore, the leading ends 275 and 375 of the top stopper back surface portions 271 and 371 are disposed at positions along the inner side surfaces 265 and 365 of the top stopper surface portions 261 and 361 in the thickness direction of the top stoppers 26 and 36. In the width direction of the fastener tapes 21 and 31, a portion in which one of the top stop surface portions 261 and 361 and the top stop back surface portions 271 and 371 protrudes from the other is not formed. Since the protruding portion is not formed in this manner, the portion of the fastener tapes 21 and 31 attached to the protruding portion is peeled off without being supported by the other of the top stop surface portions 261 and 361 and the top stop back surface portions 271 and 371. It wo n’t be lost.
（６）上止裏面部２７１，３７１は、その基端２７２，３７２側から先端２７５，３７５側に向かうに従って幅が広くなっている。
　このため、上止裏面部２７１，３７１の先端２７５，３７５側は、上止表面部２６１，３６１と連続している基端２７２，３７２側から離間しているため、上止裏面部２７１，３７１の基端２７２，３７２側と比べてファスナーテープ２１，３１からの剥れにくさが低下するが、上止裏面部２７１，３７１の先端２７５，３７５側における幅寸法を大きくしてファスナーテープ２１，３１に対する付着面積を広げることで、上止裏面部２７１，３７１の先端２７５，３７５側の部分をファスナーテープ２１，３１から剥れにくくできる。 (6) The top back surfaces 271 and 371 are wider in width from the base ends 272 and 372 toward the tips 275 and 375.
Therefore, the top ends 275 and 375 of the top stopper back surfaces 271 and 371 are separated from the base ends 272 and 372 that are continuous with the top stopper surfaces 261 and 361, so that the top stopper back surfaces 271 and 371 are separated from each other. Although the difficulty of peeling from the fastener tapes 21 and 31 is reduced as compared with the base ends 272 and 372 of the fastener tapes 21 and 31, By widening the adhesion area to 31, it is possible to make it difficult for the portions of the top stopper back surfaces 271, 371 on the tips 275, 375 side to peel off from the fastener tapes 21, 31.
（７）上止裏面部２７１，３７１は、その基端２７２，３７２側から先端２７５，３７５側に向かうに従ってスライド方向において後方に位置し、図７に示すとおり、スライド方向後方を下方とするなら、下下がりの形状となっている。
　このため、スライダー４がスライドファスナー１を閉めるスライド方向に移動され、前記上止裏面部２７１，３７１に当接すると、各上止２６，３６には、そのスライド方向前方側がファスナーテープ２１，３１の幅方向内側に向かうとともに、そのスライド方向後方側がファスナーテープ２１，３１の幅方向外側に向かう回転力が生じて、上止２６，３６の下部同士でスライダー４の案内柱部４１３を挟み込むので、スライダー４のガタツキを抑制できる。 (7) The top back surfaces 271 and 371 are positioned rearward in the sliding direction from the base ends 272 and 372 toward the distal ends 275 and 375, and as shown in FIG. , Has a shape of falling.
For this reason, when the slider 4 is moved in the sliding direction for closing the slide fastener 1 and comes into contact with the upper stopper back surfaces 271 and 371, the upper stoppers 26 and 36 have the fastener tapes 21 and 31 on the front side in the sliding direction. Since a rotational force is generated inward in the width direction and on the rear side in the sliding direction toward the outer side in the width direction of the fastener tapes 21 and 31, the guide column portion 413 of the slider 4 is sandwiched between the lower portions of the upper stoppers 26 and 36. 4 rattle can be suppressed.
（８）スライダー４は、各ファスナーエレメント列２４，３４の裏面側に配置される下板部４１２を有し、上止裏面部２７１，３７１は、スライド方向において下板部４１２の上面４１２Ｃに当接可能に対向したストッパー面２７６，３７６を有し、ストッパー面２７６，３７６は、下板部４１２の上面４１２Ｃに沿った形状とされている。
　このため、ストッパー面２７６，３７６がスライダー４の下板部４１２の上面４１２Ｃに沿った形状とされているので、ストッパー面２７６，３７６の全面を下板部４１２の上面４１２Ｃに当接させることができる。このため、スライダー４が上止２６，３６に当たる際の衝撃をストッパー面２７６，３７６の全面に分散させることができ、上止２６，３６の破損を防止できる。 (8) The slider 4 has a lower plate portion 412 disposed on the back surface side of each fastener element row 24, 34, and the upper stopper back surface portions 271 and 371 contact the upper surface 412C of the lower plate portion 412 in the sliding direction. The stopper surfaces 276 and 376 are opposed to each other so as to come into contact with each other, and the stopper surfaces 276 and 376 have a shape along the upper surface 412C of the lower plate portion 412.
For this reason, since the stopper surfaces 276 and 376 are shaped along the upper surface 412C of the lower plate portion 412 of the slider 4, the entire surfaces of the stopper surfaces 276 and 376 can be brought into contact with the upper surface 412C of the lower plate portion 412. it can. For this reason, it is possible to disperse the impact when the slider 4 hits the upper stoppers 26, 36 over the entire stopper surfaces 276, 376, and to prevent the upper stoppers 26, 36 from being damaged.
（９）スライダー４は、各ファスナーエレメント列２４，３４の表面側に配置される上板部４１１と、各ファスナーエレメント列２４，３４の裏面側に配置される下板部４１２と、上板部４１１および下板部４１２をつないだ案内柱部４１３とを有し、上止表面部２６１，３６１の表外面２６２，３６２からファスナーテープ２１，３１の裏面２１Ｂ，３１Ｂまでの寸法を寸法Ａとし、上止表面部２６１，３６１の表外面２６２，３６２から上止裏面部２７１，３７１の裏外面２７７，３７７までの寸法を寸法Ｂとし、上板部４１１の内面４１１Ｂから下板部４１２の内面４１２Ｂまでの寸法を寸法Ｃとした場合、寸法関係はＡ＜Ｃ＜Ｂである。
　このため、スライダー４がファスナーエレメント列２４，３４の上端部２４Ａ，３４Ａに配置された場合には、上止表面部２６１，３６１をスライダー４の上板部４１１および下板部４１２間に挿入できるとともに、上止裏面部２７１，３７１をスライダー４の下板部４１２に当接させて当該スライダー４を抜け止めできる。 (9) The slider 4 includes an upper plate portion 411 disposed on the front surface side of each fastener element row 24, 34, a lower plate portion 412 disposed on the back surface side of each fastener element row 24, 34, and an upper plate portion. 411 and a guide column part 413 connecting the lower plate part 412, and the dimension from the front outer surface 262, 362 of the upper stopper surface part 261, 361 to the rear surface 21 B, 31 B of the fastener tape 21, 31 is defined as dimension A, The dimension from the front outer surfaces 262, 362 of the upper stopper surface portions 261, 361 to the outer outer surfaces 277, 377 of the upper stopper rear surface portions 271, 371 is defined as a dimension B, and the inner surface 412B of the lower plate portion 412 from the inner surface 411B of the upper plate portion 411. When the dimension up to is C, the dimensional relationship is A <C <B.
Therefore, when the slider 4 is disposed at the upper end portions 24A and 34A of the fastener element rows 24 and 34, the upper stop surface portions 261 and 361 can be inserted between the upper plate portion 411 and the lower plate portion 412 of the slider 4. At the same time, the upper back surface portions 271 and 371 can be brought into contact with the lower plate portion 412 of the slider 4 to prevent the slider 4 from coming off.
（１０）上止表面部２６１，３６１の外側面２６４，３６４は、ファスナーテープ２１，３１の幅方向外側に膨出した膨出部２６４Ａ，３６４Ａを有している。
　このため、スライドファスナー１の閉鎖状態では、上止２６，３６の膨出部２６４Ａ，３６４Ａと案内柱部４１３との隙間を狭め、また、膨出部２６４Ａ，３６４Ａを案内柱部４１３に当接させることができ、これにより、ファスナーテープ２１，３１の幅方向におけるスライダー４のガタツキを抑制できる。
　さらに、上止表面部２６１，３６１および上止裏面部２７１，３７１の連続部分２７３，３７３も膨出部２６４Ａ，３６４Ａを含むので、当該連続部分２７３，３７３を大きくできて上止２６，３６の強度を高めることができる。 (10) The outer side surfaces 264 and 364 of the top stop surface portions 261 and 361 have bulging portions 264A and 364A that bulge outward in the width direction of the fastener tapes 21 and 31, respectively.
For this reason, in the closed state of the slide fastener 1, the gap between the bulging portions 264 A and 364 A of the top stoppers 26 and 36 and the guide column portion 413 is narrowed, and the bulge portions 264 A and 364 A are in contact with the guide column portion 413. Thereby, the rattling of the slider 4 in the width direction of the fastener tapes 21 and 31 can be suppressed.
Further, since the continuous portions 273 and 373 of the top stop surface portions 261 and 361 and the top stop back surface portions 271 and 371 also include the bulging portions 264A and 364A, the continuous portions 273 and 373 can be enlarged so that the top stops 26 and 36 Strength can be increased.
