Problems solved by technology

[0005] However, in the slide fastener described in the above-mentioned Patent Document 1, since the fastener elements have a substantially rectangular shape with corners, in a state where the left and right fastener elements are meshed and arranged in a straight line, the slide fastener is difficult to bend and lacks flexibility. sexual problems
In addition, in the slide fastener described in the above-mentioned Patent Document 2, since the front surface side of the fastener element is also in the shape of an element, that is, a substantially mushroom shape, there is a problem that the appearance is low.

Embodiment Construction

[0032] Hereinafter, one Embodiment of the slide fastener of this invention is demonstrated in detail based on drawing.

[0033] like figure 1 As shown, the slide fastener 10 of this embodiment has the fastener stringer 11 and the slider 30. As shown in FIG. The fastener stringer 11 includes a pair of left and right belt members 12 arranged in parallel in the left-right direction, and a pair of left and right fastener element rows 14 attached to opposite belt side edges of the pair of left and right belt members 12 13 on. And by moving the slider 30 to the longitudinal direction of the fastener stringer 11, the fastener element row 14 of a pair of left and right can be meshed and separated.

[0034] Each fastener element row 14 is composed of a plurality of fastener elements 15 using, for example, synthetic resins such as polyamide, polyacetal, polypropylene, polybutylene terephthalate (PBT), and the like. It is injection-molded on the belt side edge portion 13 of the belt m...

Abstract

There is provided a slide fastener capable of preventing core strings from being caught in a gap between upper and lower flanges, securing the flexibility of the slide fasteners when engaged, and improving the designability of the slide fasteners. The dimension (L4) of a gap (S3) between the upper and lower flanges (33a, 33b) of a slider (30) in the up-down direction is smaller than the dimension (L5) of the core strings (13a) in the front-rear direction when the core strings are pressed with the pressure of 5kgf or more. Fastener elements (15) constituting a fastener elements row (14) are independently disposed in the up-down direction of a tape member (12) when engaged. The fastener elements (15) has a design portion (16) disposed at a front side of the tape members (12), and an engaging portion (17) disposed at a rear side of the tape member (12) so as to engage with adjacent fastener elements (15), and the design portion (16) is disposed distant from the adjacent design portion (16) when engaged and having a hemispherical shape with a curved shape.

Description

technical field [0001] The present invention relates to a slide fastener, and specifically relates to a slide fastener having excellent appearance. Background technique [0002] Conventionally, there has been disclosed a slide fastener in which the outer shape of the front surface side of the fastener element is a shape similar to a button, a hook and the like, and has a decorative function (for example, refer to Patent Documents 1 and 2). The fastener element of the slide fastener described in the said patent document 1 has a substantially rectangular front part, the rear part is provided with the tooth part and the recessed part which meshes with this tooth part, and the front part is provided with decorativeness. Moreover, in the slide fastener described in the said patent document 2, the front part and the rear part of a fastener element are formed in the substantially mushroom-shaped same shape, and imitation gem (Imitation Gem) etc. are arrange|positioned on the front ...
