Description

  The present invention relates to a slide fastener and a shoe with a slide fastener in which a tape for supporting a dental dentition can be expanded and contracted in the width direction, and is particularly suitable for use in boots, boots, underground socks, and the like.

  Since the slide fastener is provided with a pair of parallel dentitions on the tape, and these dentitions can be engaged and disengaged to easily open and close the opposing edges, etc. It is attached to the kimono. For example, in a long boot, which is one of the adherends, a slide fastener is attached to a slit at an edge portion in the vertical direction facing the opening portion so that the foot can be easily put in and out. However, since there are individual differences in the thickness of the foot, if a large pulling force acts between the engaged tooth rows, the tooth may be detached midway.

  Therefore, conventionally, a slide fastener structure in which the tape is stretchable in the width direction has been proposed. For example, in Patent Document 1 below, in a warp knitted tape in which a wale is formed in the length direction of a support tape, a weft made of an inelastic yarn is provided in a section of a fastener element mounting portion, and a weft made of an elastic thread is provided in another section. A knitted support tape for a slide fastener is disclosed in which both wefts are alternately engaged in the warp direction on the stitches in the same wale at the boundary, and the structure density and tape thickness of both sections are the same. Yes.

  Moreover, the following patent document 2 discloses a fastener made of a material in which both or one of the two strips of the base tape portion of the fastener is expanded or contracted in the longitudinal direction.

Further, in Patent Document 3 below, the entire slide fastener including the dentition row can be expanded and contracted at least in the length direction, the extension is 10% or more, and the dentition pitch at the time of extension is the height of the meshing head. Disclosed is a slide fastener having stretchability that is controlled within a range that remains below twice.

  However, the knitted support tape for slide fastener disclosed in Patent Document 1 is a knitted fabric in which yarns run in a loop shape, and therefore has elasticity in the longitudinal direction, unlike a fabric in which warp yarns and weft yarns intersect perpendicularly. Moreover, the fastener disclosed by patent document 2, 3 becomes a structure which the base tape part and the whole fastener expand / contract in a longitudinal direction. That is, in the conventional configurations disclosed in Patent Documents 1, 2, and 3, in any case, the tape expands and contracts in the longitudinal direction. In general, in order to attach a slide fastener to a long boot as described above, sewing is often performed in most cases, and when the sewing part which is the opening edge part becomes long, sewing work while applying tension in the longitudinal direction Therefore, it becomes difficult to sew the slide fastener straight, and the finished product often becomes a defective product in which the slide fastener wavy.

  The present invention has been made in view of the above situation, and provides a slide fastener and a shoe with a slide fastener in which separability is prevented from being disengaged even when an excessive tensile load is applied, and the sewing allowance does not expand and contract. An object of the present invention is to improve the reliability and sewing performance of slide fasteners and shoes with slide fasteners.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The slide fastener 100 according to claim 1 of the present invention is a slide fastener 100 in which a pair of service teeth rows 11 and 11 to be opened and closed are supported by tapes 13 and 13, respectively.
The tape 13 has, in the width direction, a fixed tooth mounting portion A that supports the fixed tooth rows 11, 11, a sewn portion C that is sewn to an adherend, the fixed tooth mounting portion A, and the sewn portion. It consists of a stretchable part B intervening between C and
A weft 15 having stretchability is provided continuously in the width direction across the engagement tooth mounting portion A, the stretchable portion B, and the sewing portion C,
Non-stretchable warp yarns 17 are densely woven at a predetermined interval d in the engagement tooth attachment portion A and the sewing portion C,
The non-stretchable warp 17 is provided, and a pair of regulation yarn in each of said inextensible warp 17 in the stretchable portion B with a large distance D which said stretch unit B becomes sparse than the predetermined distance d 19 and 19 are entangled together with the stretchable weft 15.

  In this slide fastener 100, the weft 15 having elasticity is provided across the service tooth attachment part A, the expansion / contraction part B, and the sewing part C, but the non-stretchable warp is provided on the service tooth attachment part A and the sewing part C. When 17 is densely woven at a predetermined interval d, the extension of the weft 15 is restricted by the friction with the closely woven warp 17 and the expansion and contraction is prevented at the engagement tooth attaching portion A and the sewing portion C. . Accordingly, since the warp 17 is originally non-stretchable, the service tooth attachment portion A and the sewn portion C do not expand or contract with the background. On the other hand, since the warp yarns 17 are provided loosely at the interval D larger than the predetermined interval d in the expansion / contraction portion B, the expansion / contraction of the weft 15 is not restricted, and the expansion / contraction portion B can expand / contract in the tape width direction. Furthermore, a pair of restriction yarns 19, 19 are entangled with the respective warp yarns 17 in the stretchable part B together with the weft yarns 15, so that the weft yarns 15 are subjected to a certain restriction so as not to extend too much, and the warp yarns 17 in the tape width direction The displacement of the stretchable portion B sparsely woven is also suppressed.

The shoe 200 with a slide fastener according to claim 2 is provided with a slit 33 with one end 33 a facing the opening 31 and the slide fastener 100 with the slide fastener 100 according to claim 1 sewn in the slit 33. Shoes 200,
The sewn portions C, C of the tapes 31, 31 are sewn from the inside of the shoe to the slit edge 33a, which is the adherend,
Only the expansion / contraction part B is exposed to the outer side of the shoe between the engagement tooth attaching part A and the slit edge part 33a.

  In this shoe 200 with a slide fastener, for example, in the case of boots, the stretchable portion B of the tape 13 can be stretched in the tape width direction according to the expansion / contraction of the opening / closing opening 31. Further, the sewing portion C sewn on the slit edge portion 33b does not expand and contract, and an easy sewing operation without waviness is possible. Furthermore, since only the expansion / contraction part B is exposed between the engagement tooth mounting part A and the slit edge 33b, the exposed area of the slide fastener 100 is reduced.

  According to the slide fastener of the first aspect of the present invention, the wefts having elasticity are provided over the service gear mounting portion, the stretchable portion and the sewing portion, and the service gear mounting portion and the sewing portion are not stretched. Since the warp yarns are woven at a predetermined interval and the warp yarns are provided at intervals greater than the predetermined interval, the tape can be expanded and contracted in the width direction by the elastic portions woven loosely, and the slide fastener is closed Even if an excessive tensile load is applied in this state, the expansion / contraction part can be extended and the dentitions can be prevented from coming off. In addition, since the service tooth mounting portion does not expand and contract, it is possible to prevent the service tooth rows from coming off. And since the sewing part used as a seam allowance does not expand-contract, a wave | undulation does not arise and an easy sewing operation | work can be performed. Furthermore, since a pair of regulating yarns are entangled together with the wefts in each warp in the expansion / contraction part, it is possible to apply a certain regulation so as not to prevent the wefts from expanding and contracting, and not to extend too much. While preventing displacement in the tape width direction, it is possible to suppress see-through of the sparsely woven expansion and contraction.

  According to the shoe with a slide fastener according to claim 2, since the slide fastener having the stretchable portion that can be stretched in the tape width direction is sewn, for example, in the case of a long boot having a relatively long slide fastener portion, The slide fastener can be opened and closed in correspondence with feet having different thicknesses. In addition, the sewn part of the tape is sewn to the slit edge from the inside of the shoe, and only the stretchable part is exposed to the outside of the shoe between the engagement tooth attaching part and the slit edge part. It can be easily sewn to the slit edge, and since this sewn part is hidden and only the stretchable part appears, the extra tape part does not appear on the table, reducing the exposed area of the slide fastener. The design property can be improved.

Hereinafter, preferred embodiments of a slide fastener and a shoe with a slide fastener according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view of a main part of a slide fastener according to the present invention, and FIG. 2 is a cross-sectional view in a direction orthogonal to the longitudinal direction of the slide fastener according to the present invention.
In the slide fastener 100 according to the present embodiment, a pair of fastener element (service teeth) rows 11 and 11 (see FIG. 2) to be opened and closed are supported by tapes 13 and 13, respectively.

  The tape 13 has, in the width direction (left-right direction in FIG. 1), a service tooth mounting portion A that supports the service tooth row 11, a sewn part C that is sewn to an adherend (for example, a boot described later), and a service tooth. It consists of the expansion-contraction part B interposed between the attaching part A and the sewing part C. FIG. The service tooth attachment part A, the expansion / contraction part B, and the sewing part C extend in the longitudinal direction of the service tooth row 11 (vertical direction in FIG. 1).

  The tape 13 is provided with the same weft 15 having stretchability over the service gear mounting portion A, the stretchable portion B, and the sewn portion C. As the weft 15, for example, Soloflex (trade name) (polytrimethylene terephthalate fiber side-by-side conjugate yarn) manufactured by Solotec Corporation can be used.

  Non-stretchable warp yarns 17 are woven in the width direction of the tape 13 at a predetermined interval d at the engagement tooth attachment portion A and the sewing portion C of the tape 13. For example, polyester can be used as the warp 17. The warp yarns 17 are woven on the front and back sides of the tape 13 for each one or two weft yarns 15 in a direction perpendicular to the weft yarns 15. That is, the tape 13 has a structure as a woven fabric different from the knitted fabric in which the yarn runs in a loop shape. The tapes 13, 13 are not stretched in the longitudinal direction by the non-stretchable warp 17 extending along the dentitions 11, 11.

  The warp 17 is provided in the expansion / contraction part B of the tape 13 at a distance D that is larger than a predetermined distance d between the warp 17 in the service tooth attachment part A and the sewing part C. That is, in the stretchable part B, the warp yarns 17 are woven loosely from the service tooth attachment portions A and the sewn portions C in which the warp yarns 17 are densely woven.

  Further, a pair of restriction yarns 19 are entangled with the wefts 15 in each warp yarn 17 in the stretchable portion B. As the regulation yarn 19, for example, a stretchable Tetoron wooly (bulky processed yarn) can be used. The restricting yarn 19 is entangled with the warp yarn 17 intersecting on the tape front surface side of the weft yarn 15 by being hung on the back surface side of the weft yarn 15. As a result, the intersecting portion of the weft 15 and the warp 17 is appropriately tightened by the regulating yarn 19.

  The dentition rows 11 and 11 are attached to the dentition attachment portion A of the tapes 13 and 13. In this embodiment, the dental dentition 11 is made of a synthetic resin coil element, and a core string 21 is disposed in the coil. Further, at least the lower threads 23, 23 of the sewn threads of the dentitions 11, 11 are bulky processed threads of polyester.

  In this slide fastener 100, wefts 15 having stretchability are provided across the tooth attachment part A, the stretchable part B, and the sewing part C. On the other hand, the non-stretchable warp yarns 17 are densely woven at predetermined intervals in the engagement tooth attachment portion A and the sewn portion C. Thereby, in the service tooth attachment part A and the sewing part C, the extension of the weft 15 is restricted by the friction with the closely woven warp 17 and the expansion and contraction in the tape width direction is prevented. On the other hand, since the warp yarns 17 are sparsely woven at the large interval D in the stretchable portion B, the original stretchability of the weft yarn 15 is exhibited between the warp yarns 17 and 17, and the stretchable portion B is in the tape width direction. It can be stretched.

  Accordingly, since the warp 17 is originally non-stretchable, the service tooth attachment portion A and the sewn portion C do not expand or contract with the background. On the other hand, because the warp yarns 17 are provided loosely at an interval D larger than the predetermined interval d, the expansion / contraction portion B is not restricted from expanding / contracting the weft yarn 15, and the expansion / contraction portion B can expand / contract in the tape width direction. Furthermore, a pair of restricting yarns 19 are entangled with the respective warp yarns 17 in the stretchable part B together with the weft yarns 15, so that the weft yarns 15 are subjected to a certain restriction so as not to extend too much and the warp yarns 17 are displaced in the tape width direction. Is blocked. Further, since the pair of regulating yarns 19 are entangled for each warp yarn 17, the see-through of the stretchable portion B sparsely woven is also suppressed.

  As described above, according to the slide fastener 100 according to the present embodiment, the weft 15 having elasticity is provided over the service tooth attachment part A, the expansion / contraction part B, and the sewing part C. A non-stretchable warp 17 is woven at a predetermined interval d in the wearing portion C, and a warp 17 is provided at a spacing D larger than the predetermined interval d in the stretchable portion B. Even if an excessive tensile load is applied in a state where the tapes 13 and 13 can be expanded and contracted in the width direction by B and the slide fastener 100 is closed, the expansion and contraction part B can be extended and the dentitions can be prevented from coming off. Moreover, since the service tooth attachment part A does not expand and contract, it is possible to prevent detachment of the service tooth rows.

  And since the sewing part C used as a seam allowance does not expand-contract, a wave | undulation does not arise and an easy sewing operation | work can be performed. Furthermore, since a pair of restriction yarns 19 are entangled with each warp 17 in the stretchable part B together with the wefts 15, it is possible to apply a certain restriction so that the expansion and contraction of the wefts 15 is not hindered and not excessively stretched. In addition, while preventing the warp 17 from shifting in the tape width direction, it is possible to suppress the see-through of the stretchable part B woven loosely.

Next, a shoe with a slide fastener according to the present invention to which the above slide fastener is attached will be described.
FIG. 3 is an exploded side view of a shoe with a slide fastener according to the present invention, and FIG. 4 is an external view of the shoe with a slide fastener according to the present invention.
For example, a boot 200, which is a shoe with a slide fastener, is provided with a slit 33 with one end 33a facing the opening 31 of the upper part. The slide fastener 100 is sewn into the slit 33.

  The slide fastener 100 is sewn from the inside of the shoe to the slit edge 33b in which the above-described sewing portions C and C of the tapes 13 and 13 are adherends. The sewn portion C is sewn after an adhesive is applied and adhered to the slit edge 33b in advance. In the slide fastener 100, the tapes 13 and 13 are sewn between the engagement tooth attachment portion A and the slit edge portion 33b so that only the stretchable portion B is exposed to the outside of the shoe.

  In this boot 200, the stretchable portions B, B of the tapes 13, 13 can be stretched in the tape width direction according to the expansion / contraction of the opening / closing opening 31 and the rising portion 35. Further, the sewing portion C sewn on the slit edge portion 33b does not expand and contract, and an easy sewing operation without waviness is possible. Furthermore, since only the expansion / contraction part B is exposed between the engagement tooth mounting part A and the slit edge 33b, the exposed area of the slide fastener 100 is reduced.

  Therefore, according to the boot 200 according to the present embodiment, since the slide fastener 100 having the stretchable portion B that can be stretched in the tape width direction is sewn, the slide fastener 100 can be opened and closed corresponding to the feet having different thicknesses. Can be made possible. Further, the sewn portion C of the tapes 13 and 13 is sewn to the slit edge portion 33b from the inside of the shoe, and only the stretchable portion B is exposed to the outside of the shoe between the tooth mounting portion A and the slit edge portion 33b. Therefore, the sewn portion C that does not expand and contract can be easily sewn to the slit edge portion 33b, and since this sewn portion C is hidden and only the stretchable portion B appears, an extra tape portion appears on the table. Therefore, the design area can be improved by reducing the exposed area of the slide fastener 100.
