Description
本発明は、スライドファスナー用スライダーに関する。
The present invention relates to a slider for a slide fastener.
従来のスライドファスナー用スライダーとしては、胴体、カバー部材、及び引手を備え、カバー部材は、胴体の穴部からエレメント案内路に入り込む爪部と、爪部がエレメント案内路に入り込むようにカバー部材を押圧する弾性片と、胴体の上面に立設される前側柱部及び後側柱部にそれぞれ係合する前側係合片及び後側係合片と、を有し、前側柱部は、カバー部材の前側係合片と係合する前側被係合凹部を有し、後側柱部は、カバー部材の後側係合片と係合する後側被係合凹部を有するものが知られている(例えば、特許文献1参照)。
A conventional slider for a slide fastener includes a body, a cover member, and a handle. The cover member includes a claw portion that enters the element guide path from a hole portion of the body, and a cover member so that the claw portion enters the element guide path. An elastic piece to be pressed, and a front side engagement piece and a rear side engagement piece respectively engaged with a front side column part and a rear side column part standing on the upper surface of the body, and the front side column part is a cover member It is known that there is a front-side engaged recess that engages with the front-side engaging piece, and the rear column portion has a rear-side engaged recess that engages with the rear-side engaging piece of the cover member. (For example, refer to Patent Document 1).
ところで、上記特許文献1に記載の胴体を鋳造するには、上金型、下金型、エレメント案内路を形成するために胴体の前後方向に移動するスライドコア、前側柱部及び後側柱部に前側被係合凹部及び後側被係合凹部を形成するために胴体の前後方向と直交する幅方向に移動するスライドコアが必要である。そして、金型で多数の胴体を一度に鋳造するためには、多数の胴体を一方向に並べた姿勢で成形する方が効率が良い。
By the way, to cast the fuselage described in Patent Document 1, an upper die, a lower die, a slide core that moves in the front-rear direction of the fuselage to form an element guide path, a front pillar portion, and a rear pillar portion. In order to form the front-side engaged concave portion and the rear-side engaged concave portion, a slide core that moves in the width direction perpendicular to the front-rear direction of the body is necessary. And in order to cast many fuselage | body bodies at once with a metal mold | die, it is more efficient to shape | mold in the attitude | position which arranged many fuselage | casings in one direction.
そして、胴体の前後方向に移動するスライドコアで各胴体にエレメント案内路を同時成形する場合、胴体はその幅方向に並んだ姿勢で成形されるが、ここで、幅方向に移動するスライドコアを用いる場合、スライドコアが移動できる範囲を金型の幅方向にも確保する必要があり、胴体を配置するスペースが少なくなる。従って、1度の鋳造工程で少数の胴体しか得ることができず、スライドファスナー用スライダーの製造コストが増大してしまっていた。
When the element guide path is simultaneously formed in each body with the slide core that moves in the front-rear direction of the body, the body is formed in a posture aligned in the width direction. Here, the slide core that moves in the width direction is used. When used, it is necessary to secure a range in which the slide core can move in the width direction of the mold, and the space for arranging the body is reduced. Therefore, only a small number of bodies can be obtained in one casting process, and the manufacturing cost of the slider for the slide fastener has increased.
本発明は、前述した事情に鑑みてなされたものであり、その目的は、1度の鋳造工程で多数の胴体を得ることができ、製造コストを削減することができるスライドファスナー用スライダーを提供することにある。

また、左右一対の側面部91の外側面には、カバー部材50の左右一対の前側係合片56が係合する前側被係合凹部95がそれぞれ形成されている。この前側被係合凹部95は、前側係合片56の上面と対向する面を有し、前側係合片56の上面と当接してカバー部材50の上方への移動を規制する係合部95aと、前側係合片56の前面と対向する面を有し、前側係合片56の前面と当接してカバー部材50の前方への移動を規制するストッパ95bと、から構成される。
Further, on the outer side surfaces of the pair of left and right side portions 91, front engaged recesses 95 that engage with the pair of left and right front engagement pieces 56 of the cover member 50 are formed. The front-side engaged recess 95 has a surface facing the upper surface of the front-side engagement piece 56 and is in contact with the upper surface of the front-side engagement piece 56 to restrict the upward movement of the cover member 50. And a stopper 95b that has a surface facing the front surface of the front engagement piece 56 and that abuts the front surface of the front engagement piece 56 and restricts the forward movement of the cover member 50.
ストッパ95bは、左右の側面部91から前方に向けて突出するように形成されおり、折り曲げ前の状態では、左右の側面部91の切欠部91a内に配置されている。
The stopper 95b is formed so as to protrude forward from the left and right side surface portions 91, and is disposed in the notch portion 91a of the left and right side surface portions 91 before being bent.
また、左右一対の側面部91の前側被係合凹部95の上方には、カバー部材50を前側柱部90に嵌め入れる際に左右一対の前側係合片56が乗り上がるスロープ97がそれぞれ形成されている。このスロープ97は、側面部91の上端から下方に向けて下り傾斜する部分であり、上記前側被係合凹部95の係合部95aを形成するために、側面部91の上端から下方に向けて側面部91の左右方向の肉厚を漸次増加するように形成した部分である。
Further, slopes 97 on which the pair of left and right front engaging pieces 56 ride when the cover member 50 is fitted into the front column 90 are formed above the front engaged recesses 95 of the pair of left and right side portions 91, respectively. ing. The slope 97 is a portion inclined downward from the upper end of the side surface portion 91, and downward from the upper end of the side surface portion 91 in order to form the engagement portion 95 a of the front engaged recess 95. It is the part formed so that the wall thickness of the side part 91 may increase gradually.
そして、前側被係合凹部95は、図17に示すように、前側柱部90の左右のストッパ95bを不図示の折曲部材で外側に折り曲げる(塑性変形する)ことにより形成される。なお、左右のストッパ95bは、互いに左右反対方向に折り曲げられる。即ち、左側のストッパ95bは、左側に折り曲げられ、右側のストッパ95bは、右側に折り曲げられる。
Then, as shown in FIG. 17, the front engaged recess 95 is formed by bending (plastically deforming) the left and right stoppers 95 b of the front column 90 to the outside with a bending member (not shown). The left and right stoppers 95b are bent in opposite directions. That is, the left stopper 95b is bent to the left, and the right stopper 95b is bent to the right.
なお、本実施形態の第4変形例として、後側柱部40は図18に示す後側柱部100であってもよい。この後側柱部100は、基部101と、基部101の上端部から左右外方に突出する左右一対の突部102と、基部101の前面左端から前方に延びる側面視三角形状のガイド部103と、を有する。
As a fourth modification of the present embodiment, the rear column portion 40 may be the rear column portion 100 shown in FIG. The rear column portion 100 includes a base 101, a pair of left and right protrusions 102 protruding from the upper end of the base 101 to the left and right, and a triangular guide portion 103 extending forward from the left front end of the base 101. Have.
そして、本変形例では、後側柱部100を塑性変形させることなく、左右の突部102により、カバー部材50の左右一対の後側係合片57が係合する後側被係合凹部104が構成される。また、後側被係合凹部104は、後側係合片57の上面と対向する面を有し、後側係合片57の上面と当接してカバー部材50の上方への移動を規制する係合部104aを備える。また、後側被係合凹部104は、胴体20の前後方向に移動するスライドコアによって形成され、胴体20の幅方向に移動するスライドコアは必要ない。なお、本変形例では、カバー部材50の後方への移動を規制するストッパは設けなくてよい。
In this modified example, the rear engaged recess 104 in which the pair of left and right rear engagement pieces 57 of the cover member 50 are engaged by the left and right protrusions 102 without plastically deforming the rear column 100. Is configured. The rear engaged recess 104 has a surface facing the upper surface of the rear engagement piece 57 and abuts on the upper surface of the rear engagement piece 57 to restrict the upward movement of the cover member 50. The engaging part 104a is provided. Further, the rear engaged recessed portion 104 is formed by a slide core that moves in the front-rear direction of the body 20, and a slide core that moves in the width direction of the body 20 is not necessary. In this modification, it is not necessary to provide a stopper that restricts the backward movement of the cover member 50.
なお、本発明は上記実施形態に例示したものに限定されるものではなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。
It should be noted that the present invention is not limited to those exemplified in the above embodiment, and can be appropriately changed without departing from the gist of the present invention.
