Slide fastener

Abstract

The slide fastener according to the present invention includes a pair of left and right first and second fastener stringers (2a, 2b) having a fastener element row (3), box bars (4, 82) provided on the first fastener stringer (2a) , 92), the plunger (5) arranged on the above-mentioned second zipper string (2b), and a pair of first and second sliders (6a, 6b) arranged in a direction where the rear openings face each other. In addition, the first slider (6a) is arranged so as to be on the side of the box bar (4, 82, 92) compared with the second slider (6b), and the box bar (4, 82, 92) has a box bar The main body (41), the block part (42) arranged on the front end side of the box rod main body (41), and the raised parts (43, 83) formed on at least one of the upper and lower surfaces of the box rod main body (41). Furthermore, the inner surface of at least one side of the upper and lower wing plates (63, 64) in the above-mentioned first slider (6a) is formed so that the plate of the above-mentioned upper wing plate (63) or the above-mentioned lower wing plate (64) The chamfered portion (69b) whose thickness gradually decreases toward the rear opening, and the raised portion (43, 83) are arranged when the first slider (6a) collides with it and stops at the stopper portion (42). , close to the position of the above-mentioned chamfered portion (69b) of the first slider (6a). According to this, when the user slides the first slider (6a) to the regular plunger insertion position, it can give a tactile feeling like "Kaz", which can make the user realize that the first slider (6a) is moving. to the specified position. As a result, the user can habitually perform the operation of sliding the first slider (6a) to the regular plunger insertion position reliably, and can smoothly perform the insertion operation or extraction of the plunger (5) thereafter. operate.

Description

technical field [0001] The present invention relates to a disengagement operation that can be performed by having a plunger provided on one fastener stringer, a box rod provided on the other fastener stringer, and a pair of upper and lower sliders arranged so that the rear openings face each other. zipper. Background technique [0002] Conventionally, in order to open and close the left and right front pieces of clothing, a slide fastener provided with a detachable insert is often used.

Zippers that are separated at one end (lower end) are known. A slide fastener that can separate the meshed fastener element row from both ends in this way is also called a reverse opening slide fastener. ...

AI Technical Summary

Problems solved by technology

[0012] If the positions of the first and second sliders 106a, 106b are deviated from the regular plunger insertion positions, there will be a problem that the plunger 105 will be in contact with the counterpart when the plunger 105 is inserted into the first and second sliders 106a, 106b. The zipper tooth row 103 and the box rod 104 interfere, and the insertion rod 105 cannot be fully inserted into the specified position.
