Slider for slide fastener

Abstract

A slider (1) has a slider body (2), a pull tab (5), and a stop claw body (6) having a claw (61). An upper wing plate (21) of the slider body (2) has an insertion groove (32) into which the stop claw body (6) is inserted, a staking section (34) for staking and fixing the stop claw body (6), and a claw hole (37) formed so that the claw (61) can be inserted therethrough. The stop claw body (6) is provided such that the claw (61) can be inserted and extracted from an element guide path (28) through the claw hole (37) by elevating and lowering the pull tab (5). The staking section (34) is adapted so that, with the stop claw body (6) staked and fixed in position, the position in height of the upper end of the staking section (34) is the same as or lower than that of the upper surface of the upper wing plate (21). This prevents the staking section (34) from being pressed and crushed when the staking section is in contact with the pull tab (5) and other members. As a result, the size of a clearance on the inner side of the staking section (34) can be maintained for a long period of time, so that insertion and extraction operation of the claw (61) can be smoothly performed and an automatic stop mechanism of the slider (1) can stably function.

Description

technical field [0001] The present invention relates to a slider for a slide fastener provided with an automatic stop mechanism based on a stop claw, and more particularly to a slider for a slide fastener capable of protecting the operation of the stop claw and stably maintaining its sliding characteristics for a long period of time, and an automatic stop mechanism. Background technique [0002] In the past, as a slider used for a slide fastener, it is known that after the slide fastener is opened and closed, if the handle is released, the stop claw body installed inside the slider automatically moves to maintain the stop position of the slider, and when the handle is not operated In this case, a slider with an automatic stop mechanism that can maintain the sliding stop state of the slider. Moreover, the specific example of the slider provided with such an automatic stop mechanism is disclosed, for example in US Patent No. 6,647,598 (Patent Document 1), British Patent No. 12...

AI Technical Summary

Problems solved by technology

As a result, the protruding portion 86 or the fixing portion for caulking may be crushed by an external force, and the size of the gap provided when fixing the other end portion of the stop pawl 96 may not be stably maintained.

[0020] Since sufficient clearance cannot be ensured at the other end side of the stop claw body 96 like this, the movement (movement) of the stop claw body 96 in the insertion groove 83 is restricted, so the relative movement of the claw portion 97 cannot be performed smoothly. As a result of the insertion and extraction operations of the tooth guide path 84, the slide characteristic of the slider 80 is lowered, and there are problems such as that the automatic stop mechanism cannot function smoothly.
