EMBODIMENTS OF INVENTION

Hereinafter, embodiments of a slide fastener according to the present invention will be described in detail with reference to the accompanying drawings. In the following description, as for fastener tapes, a front side refers to a near side with respect to the paper surface of FIG. 1 (an upper side of a slider which will be described later, at which a pull tab is provided), a back side refers to a far side with respect to the paper surface of FIG. 1 (a lower side of the slider which will be described later, at which no pull tab is provided), an upper side refers to an upper side with respect to the paper surface of FIG. 1 (a side to which the slider is moved so as to engage fastener element rows which will be described later), a lower side refers to a lower side with respect to the paper surface of FIG. 1 (a side to which the slider is moved so as to disengage the fastener element rows which will be described later), a left side refers to a left side with respect to the paper surface of FIG. 1, and a right side refers to a right side with respect to the paper surface of FIG. 1. As for the slider, an upper side refers to a near side with respect to the paper surface of FIG. 1, a lower side refers to a far side with respect to the paper surface of FIG. 1, a front side refers to an upper side with respect to the paper surface of FIG. 1, a rear side refers to a lower side with respect to the paper surface of FIG. 1, a left side refers to a left side with respect to the paper surface of FIG. 1, and a right side refers to a right side with respect to the paper surface of FIG. 1. In addition, the right and left direction of the fastener tapes and the slider is also referred to as a width direction. The upward and downward direction of the fastener tapes is also referred to as a longitudinal direction. A tape longitudinal direction refers to the longitudinal direction of the fastener tapes, and the tape width direction refers to the width direction of the fastener tapes.

As shown in FIG. 1, the slide fastener 10 according to this embodiment includes a pair of right and left fastener tapes 20 which are made by weaving, a pair of right and left fastener element rows 30 which are respectively provided on opposing tape side edge portions 20a of the pair of right and left fastener tapes 20, the pair of right and left fastener element rows 30 each of which has a plurality of fastener elements 31, a slider 40 which is configured to engage and disengage the right and left fastener element rows 30, top end stops 11 which are respectively provided adjacent to the upper end portions of the right and left fastener element rows 30, and a bottom end stop 12 which is provided adjacent to the lower end portions of the right and left fastener element rows 30. When the slider 40 is moved upward by operating a pull tab 41, the right and left fastener element rows 30 are engaged with each other. When the slider 40 is moved downward by operating a pull tab 41, right and left fastener element rows 30 are disengaged from each other.

As shown in FIGS. 2 and 3, the fastener tapes 20 are made by weaving of warp threads 21 and weft threads 22 each of which is constituted by a multifilament thread of a polyester or polyamide fiber. The fineness of the warp threads 21 and the weft threads 22 is 330 dTex. Core strings 23a and 23b are respectively woven into the tape side edge portions 20a of the fastener tape 20 at both sides in the front-back direction. The core strings 23a and 23b are arranged adjacent to the warp threads 21 in the tape width direction, and are thicker than the warp threads 21. Each of the core strings 23a and 23b is constituted by three multifilament threads of 560 dTex as a core material and knitting yarns of 267 dTex which cover around the core material.

Stripe patterns S are respectively formed along the tape longitudinal direction in the tape side edge portions 20a at portions above the top end stops 11 and at portions below the bottom end stop 12. Each of the stripe patterns S is formed of the weft threads 22 and the core string 23a which is arranged at the front side. The stripe pattern S is formed by the difference in colors of the weft threads 22 and the core string 23a. The core string 23a is disposed so as to be raised from the front surface of the fastener tape 20 toward the front side of the fastener tape 20. The core string 23b is disposed so as to be raised from the back surface of the fastener tape 20 toward the back side of the fastener tape 20. Although the stripe patterns S are formed of the weft threads 22 and the core strings 23a in this embodiment, the stripe patterns S may be formed of the warp threads 21 and the weft threads 22. As for the colors of the core string 23a and the weft threads 22, if the core string 23a has a light color such as white, the weft threads 22 may have a dark color such as brown or dark blue. It is preferred that the colors of the warp threads 21 be the same as the color of the core string 23a. Consequently, if the color of the core string 23a is white, the colors of the warp threads 21 should be white. The colors of the warp threads 21 are not limited to the same color as the core string 23a, but the colors of the warp threads 21 can be the same as the colors of the weft threads 22 or can be different from the color of the core string 23a and the colors of the weft threads 22.

According to this embodiment, in order to form a favorable stripe pattern S, as shown in FIG. 2, the core string 23a which is disposed at the front side is woven so as to cross over three weft threads 22 (in this embodiment, two weft threads are bundled and counted as one) and then pass under one weft thread 22. The core string 23b which is disposed at the back side is woven so as to cross over one weft thread 22 and then pass under three weft threads 22. The warp threads 21 are woven so as to cross over two weft threads 22 and then pass under two weft threads 22. Consequently, since the number of the weft threads 22 which the core strings 23a and 23b cross over (the core string 23b passes under the weft threads 22 when viewed from the front side of the tape) is more than the number of the weft threads 22 which the warp threads 21 cross over, the core strings 23a and 23b are exposed to a large extent, thereby forming a favorable stripe patterns S. The number of the weft threads 22 which the core strings 23a cross over (pass under) can be any number, and is preferably 2 or more. The method of weaving the warp threads 21 as described above is intended for use in the warp threads 21 adjacent to the core strings 23a and 23b, and any other methods of weaving may be used for the other warp threads 21. The stripe patterns may be formed by making the colors of the warp threads 21 different from the colors of the weft thread 22. Such stripe patterns may collaborate with the above-described stripe patterns S. In addition, since the stripe patterns S are formed of the weft threads 22 and the core string 23a having different colors along the tape side edge portions 20a, the colors of the weft threads 22 or the color of the core string 23a is exposed through between the plurality of fastener elements 31 which are attached along the tape side edge portions 20a. Furthermore, it is possible to make the color exposed through between the plurality of fastener elements 31 uniform in the colors of the weft threads 22 or the color of the core string 23a by adjusting at least one of the intervals of the stripe patterns S and the intervals of the plurality of fastener elements 31.

As described above, according to the slide fastener 10 of this embodiment, since the stripe patterns S are formed along the tape longitudinal direction in the tape side edge portions 20a at portions above the top end stops 11 and at portions below the bottom end stop 12, it is possible to improve the aesthetic appearance of the tape side edge portions 20a at the outer side of the top end stops 11 and the bottom end stop 12 in the tape longitudinal direction.

According to the slide fastener 10 of this embodiment, since the stripe patterns S are formed by the weaving texture of the weft threads 22 and the core strings 23a which is disposed at the front side, it is possible to reduce the number of coloring processes as compared with the case in which stripe patterns are given by coloring the core strings 23a. Consequently, it is possible to reduce the manufacturing cost of the slide fastener 10.

As a first modified embodiment of this embodiment, as shown in FIG. 4, a separable end stop 50 comprised of a box pin 51, a box body 52 and an insert pin 53 may be used in place of the bottom end stop 12. In this case, the stripe patterns S are formed in the tape side edge portions 20a only at portions above the top end stops 11.

As a second modified embodiment of this embodiment, as shown in FIG. 5, the pair of right and left fastener element rows 30 may be made of metal, and first and second sliders 40a and 40b may engage and disengage the pair of right and left fastener element rows 30. The first slider 40a is disposed at the upper side of the slide fastener 10 and the second slider 40b is disposed at the lower side of the slide fastener 10 such that rear sides of the first and second sliders 40a and 40b face each other. In addition, the right and left fastener element rows 30 are engaged with each other when the first slider 40a is moved upward of the slide fastener 10 and are disengaged from each other when the first slider 40a is moved downward of the slide fastener 10. In addition, the right and left fastener element rows 30 are disengaged from each other when the second slider 40b is moved upward of the slide fastener 10 and are engaged with each other when the second slider 40b is moved downward of the slide fastener 10. In addition, the slide fastener 10 of this modified embodiment has top end stops 11 which are respectively arranged adjacent to the upper end portions of the right and left fastener element rows 30 and bottom end stops 12 which are respectively arranged adjacent to the lower end portions of the right and left fastener element rows 30. In addition, the stripe patterns S are respectively formed along the tape longitudinal direction in the tape side edge portions 20a at portions above the top end stops 11 and at portions below the bottom end stops 12. The front and rear of the second slider 40b and the right and left of the second slider 40b are opposite to the front and rear of the first slider 40a and the right and left of the the first slider 40a.

The present invention is not limited to those that were illustrated in the foregoing embodiments but can be suitably changed without departing from the technical concept of the present invention.
