Description

  The present invention relates to an attachment structure for fasteners attached to clothes, bags, and other objects, and an attachment method for fasteners.

  2. Description of the Related Art Conventionally, for example, a structure shown in FIGS. 5 and 6 is known as an attachment structure for fasteners attached to clothes, bags, and other objects.

  The fastener attachment structure shown in FIG. 5 is configured by folding back the side edge portion 23 of the surface fabric 22 to which the fastener 21 is attached, and sewing the side edge portion 23 and the fastener tape 25 using a thread 24. It is called the show fastener specification.

  Further, the fastener attachment structure shown in FIG. 6 is a ball edge (covering cloth) for making the fastener 21 inconspicuous between the end edge portion 3 of the folded surface cloth 22 and the fastener tape 25. Tamabuchi) 26 is folded in half and stitched together with thread 24, so-called single ball specification.

  By the way, in any of the above attachment structures, the number of steps for attaching the fastener is large and cumbersome, and since the fabric attached to the fastener is folded in two, the thickness of the portion where the fastener is attached There was a problem that it was not good from the viewpoint of comfort and design.

In order to solve such problems, a fastener mounting structure shown in FIG. 7 is provided. That is, in such an attachment structure, the surface fabric 22 of the chemical fiber having thermoplasticity and the synthetic resin tape 27 having thermoplasticity are bonded and integrated, and then an opening 28 is provided using a laser beam. The integrated part and the fastener tape 25 are stitched together by a thread 24, and the surface fabric 22 and the synthetic resin tape 27 are melted and solidified by a laser, and a melt-solidified part that performs the same function as a ball edge. A pair of edge processing portions 30 for preventing fraying of the yarn are formed at the same time. Thereby, the number of processes for attaching a fastener is reduced, and the thickness of a fastener part is reduced (for example, patent documents 1).
Japanese Patent No. 3467494

  However, in any of the above attachment structures, since the thread 24 is used when the fastener 21 is attached to the surface fabric 22, the seam appears on the surface fabric 22, and the thread 24 is frayed or frayed from the seam when used for many years. The product life cannot be maintained for a long time, and the mounting structure shown in FIG. 7 uses a laser. Therefore, it is expensive to mount the fastener, and the product can be manufactured at low cost. There is a problem that it is not possible.

  In view of the above problems, an object of the present invention is to provide a fastener mounting structure and a fastener mounting method that are excellent in durability of the fastener portion and can be attached at low cost.

  The fastener attachment structure according to the present invention is a fastener attachment structure that is attached to a predetermined portion of a surface fabric, and has an end that is a fold that is folded in half between the surface fabric and each fastener tape. Is provided so that the edge of the surface fabric is positioned on the fastener element side, and the covered fabric and the fastener tape are sewn at a position farther from the fastener element than the edge of the surface fabric. In addition, the surface fabric and the covering fabric are directly or indirectly joined by a joining means, and further, a coating treatment is performed on the edge of the surface fabric along the edge.

  Here, “directly” means that the surface fabric and the covered fabric are joined without using other members, and “indirect” means that the surface fabric and the covered fabric are joined using other members. It means joining.

  According to the fastener mounting structure having the above-described structure, the yarn is used only for joining the covering fabric and the fastener tape, and no seam appears on the surface fabric, and the yarn is covered by the surface fabric. This prevents the fraying and fraying, improving the durability and improving the appearance. Further, since the surface fabric does not fray from the edge due to the coating process, the process of turning back the edge of the surface fabric becomes unnecessary, and an increase in thickness can be prevented. On the other hand, the covering fabric used to make the fastener tape inconspicuous is arranged in such a manner that the edge and the slider are worn by friction, and the fold is directed toward the center of the fastener. Durability is improved.

  Moreover, in the attachment structure of the fastener according to the above-described invention, a part of the adhesive disposed on the facing portion of both the fabrics to melt the surface fabric and the covering fabric is melted from between the both fabrics and adheres to the edge. Therefore, it is possible to adopt a configuration in which a coating process is performed.

  According to the fastener mounting structure having the above-described configuration, the edge is coated by melting and solidifying the adhesive at the same time as joining the two fabrics without separately applying the coating after the fastener is attached to the surface fabric. Therefore, process integration can be achieved.

  Furthermore, the method of attaching the fastener according to the present invention is a method of attaching a fastener attached to an opening formed in a surface fabric, wherein the fold is formed as an end edge, and the end edge is an opening end of the surface fabric. A covering fabric disposed on each fastener tape so as to be positioned closer to the fastener element than the edge; a step of sewing the fastener tape at a position farther from the fastener element than the opening edge; and the covering The adhesive disposed in the facing portion between the fabric and the surface fabric is melted by the melt pressurizing means, and the pressure is applied until a part of the adhesive is pushed out between the fabrics and adheres to the opening edge. A method of attaching a fastener including the step of joining both fabrics can be employed.

  According to the attachment method of the fastener having the above configuration, since the adhesive is melted and pressurized by the melt pressurizing means, it is solidified while penetrating the covering fabric and the surface fabric, and simultaneously joining both the fabrics, A part is pushed out and solidified in the area defined by the edge and the covering fabric to cover the opening edge of the surface fabric.

  As described above, according to the first and third aspects of the present invention, the thread that stitches the coated fabric and the fastener tape is covered with the surface fabric, so that the durability of the fastener mounting structure can be improved. And the appearance can be improved.

  In addition, according to the invention described in claim 3, since it is possible to simultaneously perform the bonding and coating treatment of the coated fabric and the surface fabric, it is possible to consolidate the processes compared to the case where these are performed in separate processes. This makes it possible to reduce the time required for manufacturing and labor, thereby reducing the manufacturing cost.

  Hereinafter, an embodiment of a fastener mounting structure according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the fastener attachment structure according to the present embodiment is a fastener attachment structure attached to an opening or an edge portion provided on a surface fabric, and the surface fabric 1 and the fastener 2 are Between each of the fastener tapes 3, the folded fold line 4 is used as an end edge, and the fold line 4 is closer to the fastener element 6 side than the end edge 5 of the surface fabric 1 so as to cover the fastener tape 3. The covering fabric 7 is provided, and the covering fabric 7 and the fastener tape 3 are sewn together with a thread 8 at a position farther from the fastener element 6 than the edge 5 of the surface fabric 1. Moreover, the surface fabric 1 and the covering fabric 7 are bonded by interposing the adhesive 9. Further, the edge 5 of the surface fabric 1 is subjected to a coating process along the edge 5 when the two fabrics are joined to form a coat portion 10.

  The surface fabric 1 is provided in clothing, a bag, and other items so that the front side faces outward, and is made of natural fibers such as cotton cloth, or a single chemical fiber such as polyester, polyurethane, or nylon. Or what was made combining the plurality is used.

  The fastener 2 is an opening / closing means provided to open or close an opening portion such as a pocket of clothes, an end edge portion such as a front opening portion or a take-out portion provided on a bag, and mainly a fastener tape 3. The fastener element 6, the slider 11, and the pull handle 13 are constituent members.

  The fastener tapes 3 are provided along the longitudinal direction of the fastener 2 and are provided in pairs with substantially the same width on both sides of the fastener 2 in the width direction. The fastener element 6 is planted in a straight line. As the fastener tape 3, various tapes such as a synthetic fiber such as polyester, a cloth tape, or a tape whose surface is waterproofed are used.

  The covering fabric 7 is a member attached to the front side of the fastener tape 3 and the back side of the front surface fabric 1, and performs an opening / closing operation of the fastener 2 in view of emphasizing a design that prevents the fastener tape 3 from being exposed and standing out. In order to prevent the fastener 2 from being distorted in the longitudinal direction and preventing the slider 11 from sliding well, the fastener 2 is employed in a fastener mounting structure from the viewpoint of emphasizing the function of providing tension to the fastener 2. In addition, various fabrics can be used for the covering fabric 7 similarly to the surface fabric 1, and the same type of fabric as the surface fabric 1 can be used, or a different type of fabric can be used.

  The covering fabric 7 is formed by folding the fabric in half so as to make the tension stronger and prevent biting by the slider 11 and to withstand the friction with the slider 11. The coated fabric 7 folded in half is pasted together in advance by a thermoplastic adhesive 12 or the like to form a single elongated sheet, and has a width substantially equal to that of the fastener tape 3. In order to make the tension even stronger, the core body may be sandwiched between the coated fabrics folded in half.

  Such a covering fabric 7 is arranged such that the end edge (fold) 4 is close to the fastener element 6 and the other end opposite to the fold 4 is at substantially the same position in the width direction as the end edge of the fastener tape 3. The That is, the pair of covering fabrics 7 are arranged to face each other with a distance narrower than the width of the slider 11. The coated fabric 7 and the fastener tape 3 are sewn together at the other end edge side of the coated fabric 7. Thereby, the covering fabric 7 floats at the intermediate portion in the width direction of the fastener 2 while keeping both sides of the slider 11 and the handle 13 under the covering fabric 7 without obstructing the operability of the slider 11 and the pull handle 13. Since it is in a state, a space where the slider 11 can easily slide is secured.

  The said surface fabric 1 and the covering fabric 7 are joined using a joining means. The joining means is melt pressure adhesion using an adhesive 9, the adhesive 9 is disposed at a portion where the surface fabric 1 and the covering fabric 7 face each other, and the melted adhesive is bonded to the surface fabric 1. The fabric is solidified with the coated fabric 7 to join the two fabrics, and is extruded to a region defined by the edge 5 of the surface fabric 1 and the coated fabric 7 to solidify and coat the edge 5. When 10 is formed, a coating process is performed.

  Specifically, a synthetic resin having thermoplasticity is used as the adhesive 9, and the adhesive 9 is disposed between the surface facing the front side of the cover fabric 7 folded in half and the back side of the surface fabric 1. The In addition, the adhesive 9 is in the form of a tape or a sheet whose width is substantially equal to the width in which the surface fabric 1 and the covering fabric 7 overlap and whose length is substantially equal to the entire length of the fastener 2. Note that various types of adhesives such as polyester-based adhesives can be adopted as the adhesive 9.

  The adhesive 9 is subjected to a bonding process from the surface fabric 1 by a melt pressure device such as a high frequency welder or a microwave heating device. As a result, the adhesive was melted and solidified between the surface fabric 1 and the covering fabric 7 to form a fixing layer 14, and the edge 5 of the surface fabric 1 was pushed out between the two fabrics 1 and 7. The adhesive 9 is similarly solidified to form the coat portion 10. That is, a continuous integrated adhesive layer is formed from the region sandwiched between the surface fabric 1 and the covering fabric 7 to the region defined by the edge 5 of the surface fabric 1 and the covering fabric 7. . In the above-described joining process, the adhesive is melted and pressed by the melt pressurizing means, but the both fabrics 1 without applying pressure using an adhesive that exhibits a certain degree of fluidity when melted. , 7 may be melted to form the coat portion 10.

  As a method of attaching the fastener, a step of temporarily fixing the adhesive 9 on the back side of the portion to which the fastener of the surface fabric 1 is attached and forming an opening in the portion, and a pair of coated fabrics 7 in which the creases 4 are formed are provided. A step of disposing on the fastener tape 3 so as to face each other with a predetermined distance, a step of sewing the covering fabric 7 and the fastener tape 3 at a position farther from the fastener element 6 than the end edge 5; 3 (a), the process of superimposing the surface fabric 1 and the covering fabric 7, and the adhesive 9 is melted by the melt pressurizing means, and a part of the adhesive 9 is covered with the surface fabric 1 It is possible to employ a method comprising a step of pressing the fabric 7 and pressurizing it so as to adhere to the edge 5 of the opening and joining the fabrics 1 and 7 together.

  As a method of forming the opening, a method of punching the surface fabric 1 with a cutting die is used. Note that a method using an ultrasonic fusing machine or the like can also be adopted, and in some cases, a method of fusing with a laser can be considered. Note that the size of the opening is determined in consideration of the use of the portion to which the fastener is attached. The fastener 2 attached to the surface fabric 1 is appropriately selected and used in a size suitable for the opening. The covering fabric 7 is sewn to the fastener tape 3 so as to face each other with a distance in consideration of the width of the slider 11 and the pull handle 13 of the fastener 2.

  And in the joining process of the surface fabric 1 and the covering fabric 7, the fastener structure shown in FIG. 3 (B) constituted through the above steps is joined by the melt pressure device. That is, when the adhesive 9 positioned between the fabrics 1 and 7 is melted and pressed, the melted adhesive 9 penetrates the surface fabric 1 and the covering fabric 7 and at the same time, Extruded to the edge part. Thereafter, the temperature of the adhesive 9 decreases, and as shown in FIG. 1, the fixing layer 14 and the coating portion 10 become an adhesive layer in which they are integrally continuous.

  As described above, according to the fastener mounting structure according to the present embodiment, a thread is not used for stitching the fastener 2 and the surface fabric 1, and the fastener tape 3 and the covering fabric 7 are stitched together. Since the yarn 8 is completely covered and protected by the surface fabric 1, it is excellent in durability. Further, since the edge 5 is coated by the coat portion 10, fraying of the yarn from the edge 5 can be effectively prevented, and an increase in the thickness of the fastener portion can be prevented, so that the fastener is not clearly noticeable. It can be attached in such a way that it is excellent in design and comfortable to wear.

  Further, when the surface fabric 1 and the coated fabric 7 are bonded using a melt pressure device such as a high-frequency welder, the adhesive 9 is compared with the case where the adhesive 9 is melted by applying heat from the outside. Can be reliably melted, and the adhesive strength can be increased. Moreover, since the adhesive 9 disposed on the facing portion of the surface fabric 1 and the covering fabric 7 is melted, a coating process that covers the edge 5 at the same time as the joining of the fabrics 1 and 7 can be performed. You can reduce the number and attach the fasteners neatly.

  The attachment structure of the fastener according to the present invention is not limited to the above embodiment, and departs from the gist of the present invention that the durability can be improved and the appearance can be improved. As long as it is within the range, it can be changed as appropriate.

  For example, it is possible not only to attach the fastener so as to be inconspicuous, but also to design it so as to attract the opposite. That is, as shown in FIG. 4, the shape of the opening can be changed by changing the mold for cutting the surface fabric 1, thereby realizing fastener mounting structures of various designs. it can. In addition, the fabric used for the covering fabric 7 can be a fabric having a color or pattern different from that used for the surface fabric 1, and if implemented in combination with the deformation of the opening, the design is further enhanced. It will be a thing.

  In addition, as a method of performing the coating treatment, the fixing layer 14 and the coating portion 10 are not simultaneously formed using the thermoplastic adhesive as described above, but the bonding between the surface fabric 1 and the covering fabric 7 is performed. In addition, a method in which a coating material such as a resin is directly applied to the edge 5 can be employed. In this case, the coating treatment is not only applied to the edge 5 but also to the area including the region defined by the edge 5 of the surface fabric 1 and the covering fabric 7 and further to the upper surface of the surface fabric 1. It is done.

  Furthermore, as a joining means of the surface fabric 1 and the covering fabric 7, by using the same kind of material for both the fabrics 1 and 7, melting them in the facing portion and then integrating them, without using an adhesive or the like. A welding method can also be employed. According to this method, since it is not necessary to arrange an adhesive, the process can be further simplified. Similarly, the method of sticking both the fabrics 1 and 7 using a double-sided tape etc. as a joining means is also employable.

  In addition, as described above, instead of forming the opening after the adhesive 9 is attached to the back surface of the surface fabric 1, in the step of joining the surface fabric 1 having the opening and the covering fabric 7, The adhesive 9 may be disposed along the opening edge at the facing portion of 7. According to such a method, since the size of the adhesive 9 to be arranged can be freely set, for example, the adhesive 9 protrudes in a manner closer to the fastener element than the end edge 5 and is melt-pressed. Accordingly, it is possible to employ a coating method in which the protruding portion of the adhesive 9 melts and adheres to the edge 5.
