Description

Zipper teeth connecting belt Technical Field The present invention relates to a fastener element coupling. Background Conventionally, for example, in order to open and close left and right front bodies of clothing, a slide fastener having a separable bottom end stop, a box pin, and the like has been widely used. In addition, the slide fastener is mainly used for long jackets, ski wear, and the like. In order to improve the functionality and design of clothing, a slide fastener is known in which left and right element rows in an engaged state can be separated not only from the upper end of a fastener chain but also from the lower end. A slide fastener capable of separating element rows in an engaged state from both upper and lower ends in this way is called a double-split slide fastener. An example of a slide fastener that can be opened in both directions is disclosed in japanese patent application laid-open No. 2008-99975 (patent document 1). In the slide fastener of patent document 1, for example, a case is described in which a pair of left and right fastener stringers are engaged from a state in which the pair of left and right fastener stringers are opened (separated) to close the fastener stringers. First, a pair of upper and lower sliders attached to a fastener element row of one fastener stringer is slid and moved to a lower end portion on a rod side. Next, the insert pin is inserted into the pair of upper and lower sliders that move to the lower end portions. In this insertion operation, the insert pin is inserted into the element guide passage of the upper slider and the element guide passage of the lower slider from the shoulder opening of the upper slider. The locking piece portion of the socket rod is accommodated in the insert rod accommodating portion, and the insert rod is sufficiently inserted deep into the element guide path of the lower slider, whereby the insert operation of the insert rod is completed. Then, by sliding the upper slider upward along the element rows, the left and right element rows can be engaged to close the slide fastener. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2008-99975 Disclosure of Invention In the slide fastener disclosed in patent document 1, in a state in which the pair of right and left fastener stringers are separated, that is, in a so-called single fastener tape state, the rigidity in the front-back direction is not so high that the fastener is likely to flex, and the insertion of the insert pin may be difficult. In addition, as described above, the slider is moved upward in the fully inserted state of the insert pin, so that the right and left fastener stringers can be closed. In order to prevent such improper combination, the present inventors have conceived that, from the viewpoint of improving the startability of the slider, it is preferable that when the insert pin is fully inserted, the slider is automatically pulled up and engagement of the first element on the socket side and the insert pin is started. The present invention has been made in view of the above problems, and provides a fastener stringer having excellent operability. In order to solve the above problems, the present invention is achieved by the following configuration. [1] A fastener stringer is provided with: Fastener tapes (5 a, 5 b), and A plurality of fastener elements (70, 80) arranged and mounted on the inner side edges (6 a, 6 b) of the fastener strips (5 a, 5 b) in the width direction in the up-down direction, The fastener stringers (3A, 3B) are characterized in that, The fastener element (70, 80) comprises a main body (71, 81) mounted on the width direction inner side edge (6 a, 6 b) of the fastener tape (5 a, 5 b), and an engagement head (73, 83) extending from the main body (71, 81) to the width direction inner side, The main body portion (71, 81) of the fastener element (70, 80) has a first front and rear surface (71B, 81A) facing in a front-rear direction, a second front and rear surface (71A, 81B) facing in a direction opposite to the first front and rear surface (71B, 81A), first upper and lower surfaces (71C, 81C) facing upward or downward, and second upper and lower surfaces (71D, 81D) facing in a direction opposite to the first upper and lower surfaces (71C, 81C), The main body portion (71, 81) of one of the fastener elements (70, 80) has a first convex portion (72, 82), the first convex portion (72, 82) is provided to extend from the first front and rear surface (71B, 81A) side of the first upper and lower surfaces (71C, 81C) toward the adjacent fastener element (70, 80), The main body portions (71, 81) of the adjacent fastener elements (70, 80) have second protruding portions (76, 86), the second protruding portions (76, 86) are provided so as to extend from the second front and rear surfaces (71A, 81B) of the second upper and lower surfaces (71D, 81D) toward the one fastener element (70, 80), The first protrusions (72, 82)
