本考案は開離嵌挿具付のスライドフアスナーの
改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a slide fastener with a releasable fitting.
従来、第１図に示すような務歯がフアスナー面
に対して垂直方向に噛合するスライドフアスナー
においては、スライダー１のチヤンネル３がフア
スナー面に対して傾斜している為、スライダー１

ダー１と箱２との境界部に折曲部を生じ、その為
前記境界部において折曲した蝶棒４と該蝶棒４と
逆方向に折曲した箱棒とを使用していた。 Conventionally, in a slide fastener in which interlocking teeth engage in a direction perpendicular to the fastener surface as shown in FIG. 1, the channel 3 of the slider 1 is inclined with respect to the fastener surface.
When the slider 1 and the box 2 are in contact with each other (FIG. 1), a bend occurs at the boundary between the slider 1 and the box 2, and therefore, the insert pin 4 bent at the boundary becomes opposite to the insert pin 4. A box rod bent in the direction was used.
しかし乍ら、上記フアスナーを閉じたとき、務
歯６の噛合開始部に於て、前記蝶棒４と箱棒とが
逆方向に傾斜している為チエーン５にねじれが生
じ、チエーン割れを誘発すると共に、蝶棒４が箱
棒に挿入する際の操作性が悪い等の問題があつ
た。 However, when the fastener is closed, the chain 5 is twisted because the insert pin 4 and the box pin are tilted in opposite directions at the beginning of engagement of the engagement teeth 6, which may lead to chain cracking. In addition, there were problems such as poor operability when inserting the insert pin 4 into the box rod.
本考案はかかる従来の問題点を解決せんとする

を設けたことを特徴とするスライドフアスナーを
要旨とするものである。 The present invention aims to solve such conventional problems.In a slide fastener with a releasable fitting in which the fastening teeth engage in a vertical direction with respect to the fastener surface, when the slider and the box are in contact,
The gist of this slide fastener is a slide fastener characterized in that a thin, flexible portion is provided near the slider side of the boundary between the slider and the box between the insert pin or the insert pin and the box rod.
以下図面に基づいて詳細に説明する。 A detailed explanation will be given below based on the drawings.

れは薄肉部１０に於ても同様である。 As shown in FIG. 7, the thin section 8 is preferably formed by notching the core string section 14 of the tape 7 corresponding to the thin section 8 in advance to form a notch 13, and then injection molding the insert pin 4 as shown in FIG. In this case, the adhesion strength between the insert pin 4 and the tape 7 is increased, and there is no fear that the insert pin 4 will fall off from the tape 7 even when used for many years. This also applies to the thin wall portion 10.

つては設けなくてもよい。 FIG. 3 is a perspective view of an embodiment of the box rod 9, in which a thin wall portion 10 is provided on a portion 9a protruding from the box 2. In the figure, reference numeral 11 denotes a stopper, which engages with a concave portion 12 on the second inner surface to prevent the box bar 9 from falling off from the box 2 when the box bar 9 is attached to the box 2 as shown in FIG. . The thin wall portion 10 of the box bar 9 may not be provided depending on the case.

は冒頭で述べた如く、各々逆方向に折曲している
為、務歯６の噛合開始部にねじれを生じていたも
のである。 Fig. 5 shows a side view of the present invention with the slider lowered and the insert pin 4 inserted into the box 2, as seen from the box pin 9 side, and Fig. 6 shows a front view of the same state. , FIG. 8 shows a state in which the fastener is closed using a conventional separable fitting. Here, the insert pin 4 and box pin 9 in the conventional separable fitting
As mentioned at the beginning, since they are each bent in opposite directions, twisting occurs at the meshing start portion of the interlocking teeth 6.

務歯の確実な噛合状態を確保できるものである。 However, according to the present invention, the thin parts 8 and 10 provided on the insert pin 4 and the box pin 9, respectively, allow the insert pin to
When inserted into the box 2, the insert pin 4 box rod 9 is bent at the thin parts 8 and 10, but when the slider 1 is raised and the fastener is closed, the insert pin 4 box rod 9 becomes flexible. As a result, each of the bent portions is restored to its straight state, and a reliable meshing state of the interlocking teeth can be ensured.
