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 on 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, there are problems such as deterioration of the sliding characteristics of the slider 80 and failure of the automatic stop mechanism to function smoothly.

Embodiment 1

[0055] figure 1 It is a perspective view showing a state in which parts constituting the slide fastener slider of the first embodiment are separated, figure 2 It is a perspective view which shows the assembled state of this slider. in addition, image 3 It is a cross-sectional view showing a state in which the handle is lying on the rear opening side of the slider, Figure 4 yes image 3 Section view of line IV-IV in, Figure 5 yes image 3 The V-V line sectional view in.

[0056] In addition, in the slider of the present invention, the direction in which the slider slides so as to engage the teeth is defined as the front, and the direction in which the slider slides to separate the teeth is defined as the rear. In addition, the direction perpendicular to the upper and lower blades is defined as the vertical direction, and the direction parallel to the upper and lower blades and perpendicular to the sliding direction of the slider is defined as the left-right direction...

Embodiment 2

[0100] Figure 10 It is a perspective view showing a state in which parts constituting the slide fastener slider of the second embodiment are separated, Figure 11 It is a perspective view which shows the assembled state of this slider. in addition, Figure 12 It is a cross-sectional view showing a cross-section of a portion of the slider where a caulking portion is provided.

[0101] Compared with the slider 1 of the above-mentioned embodiment 1, the slide fastener slider 71 of the present embodiment 2 differs in the form of the riveted part 74 of the riveted and fixed stop claw body 6, and the shape of the upper wing plate 21 provided with the riveted part 74 It has substantially the same structure as the slider 1 of the said Example 1 about the structure other than a front-end|tip part. Therefore, in this second embodiment, parts and components having the same configuration as those of the slider 1 of the above-mentioned first embodiment are denoted by the same reference...

Abstract

A slider (1) has a slider body (2), a tab (5), and a locking pawl (6) having a claw portion (61). An upper blade (21) of the slider body (2) has an insert groove (32) into which the locking pawl (6) is inserted, a temporary engagement portion (34) for temporary engaging and fixing the locking pawl (6), and a claw hole (37) formed so that the claw portion (61) can be inserted therethrough. The locking pawl (6) is provided such that the claw portion (61) can be inserted into and detached from an element guide lane (28) through the claw hole (37) by elevating and lowering the tab (5). The temporary engagement portion (34) is adapted so that, with the locking pawl (6) fixed in position, the position in height of the upper end of the temporary engagement portion (34) is the same as or lower than that of the upper surface of the upper blade (21). This prevents the temporary engagement portion (34) from being pressed and crushed when the temporary engagement portion is in contact with the tab (5) and other members. As a result, the size of a clearance on the inner side of the temporary engagement portion (34) can be maintained for a long period of time, so that insertion and detachment operation of the claw portion (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...
