no. 1 Embodiment approach

[0036] First, refer to Figure 1 to Figure 7 1st Embodiment of the slider for slide fasteners concerning this invention is demonstrated.

[0037] The slide fastener slider 10 of the present embodiment is a slider with an automatic stop function, such as figure 1 and figure 2 As shown, the slider 10 for a slide fastener has the main body 20 which has the element guide passage 27 which penetrates the main body 20 in the front-back direction inside. Specifically, the main body 20 includes: an upper wing 21 and a lower wing 22, which are separated in the vertical direction and arranged side by side; a guide column 23, which connects the front ends of the upper wing 21 and the lower wing 22; The flange 24a protrudes downward along the left and right edges of the upper wing 21 ; the lower flange 24b protrudes upward along the left and right edges of the lower wing 22 . Thereby, the left and right shoulder openings 25 separated by the guide posts 23 are formed at the front porti...

no. 2 Embodiment approach

[0055] Next, refer to Figure 8 ~ Figure 13 The second embodiment of the slide fastener slider of the present invention will be described. In addition, about the same or equivalent parts as those of the first embodiment, the same reference numerals as those of the first embodiment are attached in the drawings, and descriptions thereof are omitted or simplified.

[0056] In this embodiment, if Figure 8 , Figure 9 and Figure 11 As shown, instead of the locking step portion 34 and the locking protrusion 58 of the first embodiment described above, the upper wing plates 21 constituting the lower surfaces of the left and right front side engaged recesses 31 are respectively formed with downwardly recessed locking points. The step portion 61 is fixed, and locking protrusions 62 protruding downward and locking with the locking step portion 61 are respectively formed on the front end lower surfaces of the left and right paired front engaging pieces 56 .

[0057] On the left and ...

no. 3 Embodiment approach

[0065] Next, refer to Figure 14 ~ Figure 16 A third embodiment of the slide fastener slider of the present invention will be described.

[0066] The slide fastener slider 10 of the present embodiment is a slider with an automatic stop function, such as Figure 14 and Figure 15 As shown, the slider 10 for a slide fastener has the main body 20 which has the element guide passage 27 which penetrates the main body 20 in the front-back direction inside. Specifically, the main body 20 includes: an upper wing 21 and a lower wing 22, which are separated in the vertical direction and arranged side by side; a guide column 23, which connects the front ends of the upper wing 21 and the lower wing 22; The flange 24a protrudes downward along the left and right edges of the upper wing 21 ; the lower flange 24b protrudes upward along the left and right edges of the lower wing 22 . As a result, left and right shoulder openings 25 separated by guide posts 23 are formed at the front portion...

Abstract

Provided is a slider for a slide fastener, whereby several bodies can be obtained in one casting process and production costs can be reduced. A cover member (50) has a pair of right and left front-side engagement pieces (56) that engage with a front-side pillar section (30) and a pair of right and left rear-side engagement pieces (57) that engage with a rear-side pillar section (40). Front-side recessed sections for engagement (31) having a surface facing the upper surface of the front-side engagement pieces (56) are formed in the right and left side surfaces of the front-side pillar section (30); rear-side recessed sections for engagement (41) having a surface facing the upper surface of the rear-side engagement pieces (57) are formed in the right and left side surfaces of the rear-side pillar section (40); and the front-side and rear-side recessed sections for engagement (31, 41) are formed penetrating along the front-rear direction of the bodies (20).

Description

technical field [0001] The invention relates to a slider for a slide fastener. Background technique [0002] A conventional slider for a slide fastener is known (for example, refer to Patent Document 1): the slider for a slide fastener includes a main body, a cover member, and a handle, and the cover member includes a claw portion, an elastic piece, a front engaging piece, and a rear engaging piece. The above-mentioned claw part enters the sprocket guide passage from the claw hole of the main body, and the above-mentioned elastic piece presses the cover member so that the claw part enters the sprocket guide passage. The front side column part provided on the upper surface of the main body is engaged with the rear side column part, the front side column part has a front side to be engaged concave part engaged with the front side engaging piece of the cover member, and the rear side column part has a The rear side to be engaged recessed part which the rear side engaging piece...
