Description

Slide fastener

The present invention relates to a slide fastener.

】 Slide fasteners are widely used as opening / closing tools in daily necessaries such as clothing, bags, shoes and sundries, as well as in industrial products such as tents.

In general, a slide fastener is inserted between a fastener stringer having an element row that is a meshing portion of a fastener along a side edge of a pair of long tapes and a pair of left and right fastener stringers to mesh and separate the element row. Is mainly composed of a slider for controlling the opening and closing of the fastener.

Conventionally, slide fasteners are generally sewn to the main body of an article. However, recently, in order to obtain a sense of unity with an article, a technique for attaching a fastener element to the fabric itself constituting the main body has been proposed (eg, International Publication No. 2017/094145 (Patent Document 1)). FIG. 13 shows a cross-sectional view of the side edge portion of the tape member described in FIG. In Patent Document 1, the tape side edge portion (22) of the tape member (20) is continuously arranged in the tape width direction from the tape main body portion (21), and the first string portion (24a) is formed. 1 tape fixing part (22a), a bent part (22b) extending from the first tape fixing part (22a) and bent into a substantially U shape on the back side of the member, and from the bent part (22b) to the inside of the tape It has described that it has the 2nd tape fixing | fixed part (22c) extended toward. The second tape fixing portion (22c) is superimposed on the first tape fixing portion (22a) and is sewn to the first tape fixing portion (22a) by the tape sewing line (29).

Also, among slide fasteners, open fasteners that allow a pair of fastener stringers to be separated are known. In an open fastener, a reinforcing film is generally attached to strengthen an attachment of an opening fixture fixed to the lower end of an element row (for example, Japanese Utility Model Publication No. 61-77811). Patent Document 2)). In FIG. 14, sectional drawing of the side edge part of the fastener tape described in FIG. 6 of patent document 2 is shown. In Patent Document 2, the side edge of the adherend (10) is folded in half and sandwiched between the front surface and the reinforcing piece (4) protruding from the surface of the tape (1), and further, the reinforcing piece ( 4) A slide with a separation fitting that is brought into contact with the back surface of the tape (1) and the front and back reinforcing pieces (4) and the adherend (10) are welded to the tape (1) at once by ultrasonic welding or high frequency welding. Fasteners are described.

International Publication No. 2017/094145 Japanese Utility Model Publication No. 61-77811

In Patent Document 1, the side edges of the fastener tape are folded back, thereby obtaining the effect of improving the aesthetics and improving the fixing strength of the core string. However, in patent document 1, consideration with respect to application to an open fastener is insufficient. That is, in patent document 1, although the 2nd tape fixing | fixed part (22c) is sewn on the 1st tape fixing | fixed part (22a) by the tape sewing line (29), the edge of a 2nd tape fixing | fixed part (22c) (A) is exposed. In the open fastener, when a pair of fastener stringers are separated and joined, the user's hand or the like is likely to come into contact with the periphery of the opening, and the second tape fixing portion (22c) is touched by the edge (A). There is a risk that the two-tape fixing portion (22c) may be rolled. When a tensile force is repeatedly applied to the bent portion, the second tape fixing portion (22c) may be peeled off and the slide fastener may be damaged. For this reason, it is desirable to prevent the folded tape member from curling.

Patent Document 2 discloses an open fastener and discloses a sticking of a reinforcing film in the vicinity of the opening device. However, similarly to Patent Document 1, the folded edge (B) of the adherend (10) is disclosed. Is exposed, the edge (B) in the vicinity of the opening device may hit the user's hand or the like when the fastener stringer is separated and joined, and the adherend (10) may be wound. Therefore, even if the technical idea of patent document 2 is combined with patent document 1, the said problem cannot be solved.

The present invention was created in view of the above circumstances, and in one embodiment, in a slide fastener in which an opening device is fixed to a side edge of the folded fabric, the folded fabric can be prevented from curling. Provide slide fasteners. Moreover, this invention makes it a subject to provide the articles | goods provided with such a slide fastener in another one Embodiment.

FIG. 5 illustrates a schematic cross-sectional structure when an adhesive is interposed between the overlapping portions. FIG. 6 is a usage example of an article using the slide fastener according to the first embodiment.

In the following description, the vertical direction refers to the length direction (L) of the fastener element row, and is the same direction as the sliding direction in which the slider slides. Moreover, the left-right direction means a direction orthogonal to the length direction (L) of the fastener element row and the front and back direction of the fabric, and is the same as the width direction (W) of the fastener element. Further, the front and back direction of the fabric is a direction perpendicular to the main surface of the fabric, and is the same as the thickness direction (T) of the fastener element.

As shown in FIGS. 1A and 1B, the slide fastener (100) according to the first embodiment is a pair of fabrics (110) in which one side edges (111) face each other, and each fabric (110) is A pair of fabrics (110) having overlapping portions (113a, 113b) with one side edge (111) as a folded portion (112), and one side edge on the overlapping portions (113a, 113b) of each fabric (110) A fastener element row (120) fixed along (111) and one side edge (111) on the overlapping portion (113a, 113b) of each fabric (110) adjacent to one end of the fastener element row (120). ) Fixed along the other end of the fastener element row (120), a fastener (140) fixed adjacent to the other end of the fastener element row (120), and a puller (151). The slider (150) that separates and meshes the pair of fastener element rows (120), and the edge of the overlapping portion (113a, 113b) from the overlapping portion (113a, 113b) to which the opening tool (130) is fixed ( 114) and a film (160) affixed to each fabric (110) over a portion where the overlapping portions (113a, 113b) do not exist.

There is no particular limitation on the fabric constituting the slide fastener (100). Examples of the fabric include woven fabric, knitted fabric, nonwoven fabric, animal natural leather, synthetic leather, and resin film. It is also possible to use a plurality of doughs superimposed on each other, and a water stop film may be attached to the surface. Furthermore, the fabric (110) may be waterproof and breathable. For example, a synthetic resin film such as Gore-Tex (registered trademark) can be used as the fabric having waterproof and moisture permeability.

There is no limitation on the types of elements constituting the fastener element row (120). For example, a single element typified by a resin element and a metal element, and a continuous element typified by a coiled resin element can be used. A fastener element row formed of synthetic resin elements can be formed by fixing a plurality of synthetic resin elements to one side edge (111) of the fabric (110) at a constant interval by injection molding. The fastener element row by metal elements can be formed by caulking and fixing a plurality of metal elements at a certain interval to one side edge (111) of the fabric (110). The fastener element row by the coiled resin element can be formed by sewing the coiled element on one side edge (111) of the fabric (110) with a suture thread.

Each fastener element (120) can have the same shape as a fastener element arranged in a conventional fastener, and there is no particular restriction. FIG. 2A shows an example of a fastener element (120) applicable to a waterproof fastener. As shown in FIG. 2A, each fastener element (120) includes a first element portion (120a) disposed on the first main surface (115) side of the fabric (110) and a second element of the fabric (110). It has the 2nd element part (120b) provided in the main surface (116) side and provided with the shape different from the 1st element part (120a).

Here, the first main surface (115) of the fabric (110) is the main surface on the side having the edge (114) of the overlapping portions (113a, 113b) formed by folding the fabric (110). Say. The second main surface (116) of the fabric (110) is the main surface opposite to the first main surface (115).

In the fastener element (120) shown in FIG. 2A, the first element part (120a) is formed continuously from the first body part fixed to the fabric (110) and the first body part, and has a constricted shape. It has a neck and an oval meshing head formed continuously from the neck. In the fastener element (120) shown in FIG. 2A, the second element portion (120b) includes a substantially rectangular parallelepiped second trunk portion fixed to the fabric (110), and an element head protruding in the element width direction from the second trunk portion. Part. The element head of the second element portion (120b) has a shape in which the dimension in the length direction (L) of the fastener element row (120) gradually decreases in two steps toward the tip of the element head.

As shown in FIG. 2A, each fabric (110) includes a first string portion (117) fixed to the overlapping portion (113a) on the first main surface (115) side of the fabric, and a second fabric. And a second string portion (118) fixed to the overlapping portion (113b) on the main surface (116) side. In the illustrated embodiment, the first string portion (117) is formed so as to bulge in a direction away from the overlapping portion (113a) on the first main surface (115) side of the fabric (110). The second string portion (118) is formed so as to bulge in a direction away from the overlapping portion (113b) on the second main surface (116) side of the fabric (110). . Fastening strength can be improved by fixing the fastener element row (120) so as to sandwich the first string portion (117) and the second string portion (118).

As illustrated in FIG. 2B, the fabrics (110) facing each other in the overlapping portions (113a, 113b) may be sewn together by a sewing line (180). Thereby, the effect which prevents that an overlapping part (113a, 113b) collapses can be acquired.

1st string part (117) and 2nd string part (118) can be fixed with one needle thread, respectively. More specifically, the first needle thread (117a) does not pierce the first string portion (117) in the overlapping portion (113a) on the first main surface (115) side, as shown in FIG. As described above, the first string portion (117) can be fixed by tightening while repeating a certain stitch form in the element row direction. Similarly, the second string portion (118) can be fixed to the overlapping portion (113b) on the second main surface (116) side by using the second needle thread (118a).

The opening tool (130) in the present embodiment is generally called a separation / insertion tool, and as shown in FIGS. 4A and 4B, one of the overlapping portions (113a, 113b) of the fabric (110) on the right side of the paper surface. At the side edge, the butterfly pin (131) disposed adjacent to the fastener element row (120) and the one side edge of the fabric (110) on the left side of the paper is disposed adjacent to the fastener element row (120). A box bar (132) and a box body (133) formed integrally with the box bar (132) at the lower end of the box bar (132) and capable of accommodating the butterfly bar (131) are provided. A meshing protrusion (131a) extends from the upper end of the butterfly stick (131) toward the box bar (132) so as to engage with a locking part (not shown) inside the box bar (132).

In the present embodiment, there is an overlapping portion (113a, 113b) straddling the edge (114) of the overlapping portion (113a, 113b) from the overlapping portion (113a, 113b) to which the opening tool (130) is fixed. A film (160) is affixed to each fabric (110) over the portion that is not (in the left-right direction). Thereby, the edge (114) of the overlapping portion (113a) to which the opening tool (130) is fixed is not exposed. Therefore, even if the dough (110) around the opening device (130) is gripped by a human finger and the butterfly stick (131) is stored in the box (133), the overlapping portion around the opening device (130) Since the human hand does not touch the edge (114) of (113a), it is possible to prevent the fabric (110) on the first main surface (115) side from curling.

The film (160) has a function of reinforcing the fabric (110) on the first main surface (115) side. The area to which the film (160) is attached is not limited to the above-described range, and may be additionally attached to other areas. For example, the overlapping portion (113a, 113b) straddles the edge (114) of the overlapping portion (113a, 113b) from an arbitrary position of the overlapping portion (113a, 113b) where the opening tool (130) is not fixed. A film (160) may be affixed to each fabric (110) over a portion where there is no presence (in the left-right direction). In the slide fastener (100) according to the present embodiment, as shown in FIG. 1B, a film (110) is attached to the end of the fabric (110) extending above the stopper (140) (the side away from the fastener element row). 161) is affixed.

The film (160) is preferably attached only to the first main surface (115) side as shown in FIG. 4B. Thereby, since the film (160) is hidden and cannot be seen from the second main surface (116) side, the aesthetic appearance of the second main surface side can be improved. Further, since the edge of the film (160) is not exposed on the second main surface (116) side, an effect that the film (160) is difficult to peel from the second main surface (116) side is also obtained.

As shown in FIG. 4B, the film (160) overlaps the fabrics (110) so as to cover at least a part of the first string portion (117) fixed to the overlapping portions (113a, 113b). Affixing to the first main surface (115) side of the mating portions (113a, 113b) is preferable from the viewpoint of improving the adhesive strength of the film (160) and aesthetics.

As shown in FIG. 4B, the film (160) preferably has a portion interposed between the opening tool (130) and each fabric (110). In particular, it is preferable that the edge in the left-right direction of the film (160) that is closer to the folded portion (112) is interposed between the opening tool (130) and each fabric (110). . With this configuration, an effect that the film (160) is hardly peeled off from the fabric (110) is obtained.

The length in the width direction of the fastener element row (120) of the film (160) is, as shown in FIG. 4B, the fastener element row (110) of the fabric (110) to which the film is attached from the viewpoint of production cost and aesthetics. 120) is preferably shorter than the length in the width direction (W) (left-right direction).

The film (160) extends a predetermined length (D) or more from the edge (114) of the overlapping portion (113a) in the width direction (W) (left-right direction) of the fastener element row (120). However, the film (160) is preferable from the viewpoint of preventing the overlapping portion (113a) on the first main surface (115) side from curling without peeling off from the first main surface (115) side. Specifically, the predetermined length (D) is preferably 1 mm or more, more preferably 2 mm or more, and even more preferably 3 mm or more. However, the length (D) is preferably 4 mm or less from the viewpoint of manufacturing cost.

The material of the film (160) is not particularly limited, but a polyamide (nylon) -based material is preferable from the viewpoint of easily and reliably sticking the film (160) to a predetermined portion. These may be used individually by 1 type and may use 2 or more types together.

The thickness of the film (160) is not limited and can be set as appropriate. The thickness of the film (160) is preferably 0.2 mm or more, and more preferably 0.25 mm or more, from the viewpoint of convenience during use.

Even if the film (160) is pasted across the edge (114) of the overlapping portions (113a, 113b), the overlapping portion (113a) on the first main surface side (115) side and the second main surface A slight clearance may occur between the side (116) and the overlapping portion (113b). In such a case, there is a risk that the film (160) may be peeled off and the fabric (110) may be damaged as the clearance increases due to repeated use such as opening and closing of the slide fastener (100). Therefore, as shown in FIG. 5, it is preferable to have an adhesive region where the facing fabric surfaces are bonded to each other in the overlapping portions (113a, 113b). And from the viewpoint of preventing breakage in the vicinity of the opening device, the adhesion region and the region where the film (160) is adhered are observed from a direction parallel to the thickness direction (T) of the fabric (110). More preferably, there is an overlapping region. Thereby, since it becomes difficult to produce clearance in the overlapping part (113a, 113b) around the opening tool (130), the fabric (110) can be prevented from curling even when the slide fastener (100) is repeatedly opened and closed. The durability of (110) can be improved. More preferably, the adhesive region extends continuously in the vertical direction (L) so as to protrude from both ends of the film (160) in the vertical direction (L).

The formation method of the adhesion region is not particularly limited, but for example, it can be formed by interposing an adhesive between the facing fabric surfaces. Examples of the adhesive include a thermosetting resin adhesive, an elastomer adhesive, a thermoplastic resin adhesive, and a hot melt adhesive. The adhesive may be provided in the form of a double-sided adhesive tape. Further, the overlapping portions (113a, 113b) can be thermocompression-bonded or welded without interposing an adhesive. In addition to ironing, an ultrasonic welding machine, a high-frequency welding machine, or the like can be used for bonding.

When a double-sided thermal adhesive tape is used as the adhesive, the overlapping portion (113a, 113b) on the first main surface (115) side or the second main surface (116) side is heated and pressed by a heating means such as an iron. By doing so, it is possible to bond the opposite fabric surfaces of the overlapping portions (113a, 113b).

Each fabric (110) can be provided as a long tape body. Such a tape body is formed, for example, by cutting the fabric (110) into a long tape shape. It is also possible to manufacture a slide fastener by directly forming a plurality of fastener elements on the fabric (110) by injection molding using a fabric constituting a part of an article body such as clothing. In this case, the pair of fabrics (110) whose side edges oppose each other can be seamlessly integrated with the main body of the article. This makes it possible to obtain a slide fastener that has a sense of unity with the article. At this time, it is aesthetic that the second main surface (116) of the fabric (110) forms the outer surface of the article, and the first main surface (115) of the fabric (110) forms the inner surface of the article. And it is preferable from a viewpoint of peeling prevention of a film (160).

Referring to FIGS. 1A and 1B, each fabric (110) is the longitudinal edge of the fastener element row (120) of the opening device (130) and is far from one end of the fastener element row (120). It may extend beyond one end edge (lower end in the figure) in a direction (downward direction in the figure) from one end of the fastener element row (120) toward the opening tool (130). By the said structure, since the part to which the opening tool (130) is attached to the cloth | dough (110) can be made into the whole opening tool (130), there exists an advantage which can obtain easily the attachment strength to cloth | dough (110). Further, the fabric portion below the opening tool (130) has an advantage that it can be used as a portion for finishing an article to which a slide fastener such as clothes is attached.

The article to which the slide fastener is attached is not particularly limited, but can be selected from the group consisting of clothes, shoes, bags, and accessories. Moreover, the example of application to the clothing (1000) of the slide fastener which concerns on this invention is shown by FIG. In this case, the pair of fabrics (110) is seamlessly integrated with the front body of the clothing (1000).

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS. 7A to 9B. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

FIG. 7A is a schematic front view of a slide fastener according to the second embodiment. FIG. 7B is a schematic rear view of the slide fastener according to the second embodiment. FIG. 8 is a schematic XX cross-sectional view of FIG. 7A. FIG. 9A is a rear view schematically showing a state in which the opening device provided in the slide fastener according to the second embodiment is separated. FIG. 9B is a schematic XX cross-sectional view of FIG. 9A.
