By the way, the stud is originally used to connect the members to each other. Therefore, it is generally made of metal, and as a result, it contributes to giving the impression that the school bag or the like on which the stud is used is robust and has excellent durability. Therefore, it is kept in mind that the decorative studs that are not used for connecting members, for example, the second stud of Patent Document 1, are also made of metal, and the decoration applied to the head of the stud is also rhinestone or It is made of hard glass, ceramics, ceramics, etc., and the studs are used to give the school bag a sense of robustness and luxury.

However, such an image can cause a mismatch. In other words, when the hanging lid was decorated with a design that gave a soft and gentle impression, there was a case where a sense of unity could not be obtained with the studs that had a hard image, and the impression was erratic. In Patent Document 2, a part of the stud is hidden by the ribbon made of leather, but when the ribbon is attached to the stud, the leather is sandwiched between the screw head of the mounting screw and the flange portion of the main body screw. Therefore, the flange portion located on the outside of the leather is completely exposed.

Therefore, an object of the present invention is to provide a decorative stud that can give a soft and gentle impression and a school bag using this decorative stud.

The decorative stud of the present invention has a stud body 2 having a head 22c protruding from the adherend 10, and a head while interposing between the adherend 10 and the head 22c and directly facing the adherend 10. It is characterized in that it includes a soft member 3 that covers the portion 22c.

In the decorative stud having the above configuration, it is preferable that the soft member 3 is an embroidered body.

Further, it is preferable that the embroidery body 3 is formed by laminating a plurality of embroidery sheets 4, and the head 22c is located between the embroidery sheets 4. Further, it is preferable that the embroidery sheet 4 is sewn on the head 22c. Further, it is preferable that another embroidery sheet 4 is adhered to the embroidery sheet 4 sewn on the head 22c.

An embroidery sheet 4 that abuts on the upper surface of the head 22c is sewn on the head 22c, and the embroidery sheet 4 may be adhered to the upper surface and the lower surface of the sewn embroidery sheet 4 with an adhesive, respectively. ..

It is preferable that the plurality of lower layer embroidery sheets 4 have the same shape, and the upper layer embroidery sheet 4 has a shape different from that of the lower layer embroidery sheet 4 while being within the range of the lower layer embroidery sheet 4.

Further, it is preferable that the school bag is attached to the connecting portion between the hanging lid 11 and the connecting belt 12.

The school bag of the present invention is characterized in that any of the above decorative studs 1 is attached.

In the decorative stud of the present invention, since the head of the stud body is covered with a soft member, when the stud is attached to the adherend, a soft and gentle impression can be given. Further, since the soft member is interposed between the adherend and the head and directly faces the adherend, it is difficult to recognize the head from the outside, and it is as if the entire stud is from the soft member. You can feel it as if it were composed, or you can give the impression that you are not using studs. Also, if a stud of similar size is made of metal, there may be problems with weight and safety, but such concerns do not occur.

Further, when the soft member is an embroidered body, the texture peculiar to embroidery can give an impression completely different from the conventional studs.

When the embroidery body is made by stacking a plurality of embroidery sheets and the head is located between the embroidery sheets, it is easy to hide the head and to secure the attachment strength between the head and the embroidery body.

When the embroidery sheet is sewn on the head, the embroidery body can be firmly attached to the head.

When another embroidery sheet is adhered to the embroidery sheet sewn on the head, the sewing thread can be hidden.

When an embroidery sheet that abuts on the upper surface of the head is sewn on the head and the embroidery sheet is adhered to the upper surface and the lower surface of the sewn embroidery sheet with an adhesive, the sewing thread and the adhesive are used. The embroidery body can be attached to the head and the sewing thread can be hidden.

When multiple lower layer embroidery sheets have the same shape and the upper layer embroidery sheet has a different shape from the lower layer embroidery sheet while being within the range of the lower layer embroidery sheet, a complicated three-dimensional shape is expressed. be able to.

When attached to the connecting part between the hanging lid of the school bag and the connecting belt, it can give a soft and gentle impression that is completely different from the conventional studs. Therefore, when the hanging lid is decorated with a design that gives a soft and gentle impression, it is possible to produce a harmonious sense of unity.

Next, the decorative studs of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the decorative stud 1 of the present invention is composed of a metal stud body 2 and a soft member 3 attached to the stud body 2.

The stud body 2 is a so-called set screw or single screw type screw, and is composed of a male member 21 and a female member 22.

The male member 21 includes a male screw portion 21a and a seat portion 21b integrally formed at the lower end of the male screw portion 21a. The seat portion 21b has a disk shape, and its outer diameter is larger than the outer diameter of the male screw portion 21a. Further, a groove 21c used when rotating with a driver or the like is provided on the lower surface of the seat portion 21b.

The female member 22 includes a shaft portion 22a in which a female screw 22b is engraved inside, and a head portion 22c integrally formed at the upper end of the shaft portion 22a. The head portion 22c has a disk shape, and its outer diameter is larger than the outer diameter of the shaft portion 22a. Further, the head portion 22c is provided with a sewing hole 22d penetrating in the vertical direction (plate thickness direction). A plurality (4) of the sewing holes 22d are provided at equal intervals in the vicinity of the outer edge of the head portion 22c. The upper surface and the lower surface are flat except for the sewing hole 22d. When the stud body 2 is attached to the adherend (school bag or the like) 10 (see FIG. 8), the head 22c protrudes from the adherend 10. The same applies to the seat portion 21b.

The soft member 3 is made of an embroidered body. The embroidery body 3 is configured by laminating a plurality of embroidery sheets 4 having a width wider than the head 22c of the stud body 2. As shown in FIGS. 3A to 3C, the planar shapes of the embroidery sheets 4 are a plurality of lower layer embroidery sheets 4A, an upper layer embroidery sheet 4B laminated on the lower layer embroidery sheet 4A, and an upper layer embroidery sheet 4B. It is different from the top layer embroidery sheet 4C laminated on top. Specifically, the planar shape of the lower layer embroidery sheet 4A is a contour in which a knot is tied to the center of two types of ribbons slightly offset from each other, and the planar shape of the upper layer embroidery sheet 4B has two types. The contour of only one of the ribbons, and the planar shape of the uppermost embroidery sheet 4C is the contour of only the central knot. That is, the plurality of lower layer embroidery sheets 4A have the same shape as each other, and the upper layer and the uppermost layer embroidery sheets 4B and 4C are within the range of the lower layer 4A and 4B embroidery sheet 4 from themselves, and the lower layers 4A and 4B are embroidered. It has a different shape from the sheet 4 (see FIG. 4).

By the way, as shown in FIG. 5, the embroidery sheet 4 has a flexible base material 41, an embroidery 42 provided on the base material 41, and heat adhesion provided on the back surface side (the bobbin thread 42b side of the embroidery 42 described later). It is composed of an agent layer 43. However, as will be described later, the thermal adhesive layer 43 may not be provided.

The substrate 41 is preferably a woven fabric made of a thermoplastic resin that can be heat-cut and does not melt at the temperature of thermal bonding, a woven fabric made of a thermoplastic synthetic fiber, or a synthetic resin film. The substrate 41 does not need to have high strength, tear resistance, or strength against thread tension. Further, the substrate 41 may be melted when heat-bonded. However, since the embroidery sheet 4 is handled alone during the manufacturing process, a predetermined strength is required. Therefore, plant fibers such as cotton and linen, animal fibers such as wool, mesh fabrics woven with synthetic fibers, woven fabrics, woven fabrics, and the like may be used.

When the base material 41 has a heat-cutting property, a large number of embroidery 42 formed on the large base material 41 can be easily individually separated (cut) along the contour. However, when other cutting methods such as die cutting are adopted, the heat cut property does not have to be obtained. When cutting, it is preferable to attach a heat-resistant film on the upper surface so that the film does not fall apart after being separated.

For the embroidery 42 provided on the base material 41, a needle thread 42a located on the upper side of the base material 41 and a bobbin thread 42b located on the lower side of the base material 41 are used. The needle thread 42a and the bobbin thread 42b are required to have predetermined tensile strength, wear resistance, and weather resistance. In addition, embroidery may be performed with one embroidery thread.

The thermal adhesive layer 43 is an adhesive that melts by heating, flows into the gaps between the substrate 41 and the embroidery 42, and is integrally bonded to each other after cooling, and a hot melt adhesive or the like is suitable. As the material of such a thermal adhesive layer 43, for example, polyethylene, polypropylene, or the like can be adopted.

In order to manufacture the above embroidery sheet 4, an embroidery thread (upper thread 42a, bobbin thread 42b) is sewn onto the base material 41 so as to have a predetermined shape to provide the embroidery 42, and a thermal adhesive layer is provided on the lower surface of the embroidery 42. It is completed by providing 43. If necessary, a release paper may be attached to the heat adhesive layer 43. The thermal adhesive layer 43 may be formed by applying it in advance and drying it, or may apply a liquid adhesive immediately before attaching. When the adhesive is applied at the time of bonding, it is not necessary to provide the heat adhesive layer 43 on the embroidery sheet 4, but it is of course possible to provide the heat adhesive layer 43. As long as the predetermined durability and adhesive strength are satisfied, an adhesive or adhesive glue that adheres by pressure can be used instead of the thermal adhesive layer 43.

In manufacturing the decorative stud 1, as shown in FIG. 6, first, one lower layer embroidery sheet 4A is brought into contact with the upper surface of the head 22c of the stud body 2, and the sewing hole 22d of the head 22c is used. Then, the embroidery sheet 4A is sewn on the head 22c. At this time, it is wider than the head 22c and has a sufficient distance from the outer edge of the head 22c to the outer edge of the embroidery sheet 4A so that the head 22c is hidden when the head 22c is sandwiched between the other embroidery sheets 4A. It is preferable to sew it in a place where it can be secured. The sufficient distance is, for example, the same as or longer than the thickness of the head 22c (in the plate thickness direction).

Subsequently, as shown in FIG. 7, another embroidery sheet 4A is superposed on the embroidery sheet 4A sewn on the head 22c. Specifically, the embroidery sheet 4A having the same shape is superposed on the upper surface and the lower surface of the embroidery sheet 4A sewn on the head 22c. The embroidery sheet 4A overlapping the lower surface of the embroidery sheet 4A sewn on the head 22c is provided with an insertion hole 4A1 for passing the shaft portion 22a. The diameter of the insertion hole 4A1 is the same as or smaller than the outer diameter of the shaft portion 22a. As a result, in addition to the lower surface of the embroidery sheet 4A sewn on the head 22c, the lower surface of the head 22c is also covered with the embroidery sheet 4A, the sewing thread 5 is hidden, and the head 22c can be recognized from the outside. It will be difficult.

It is preferable that the embroidery sheets 4 are adhered to each other with an adhesive. This is because the sewing thread 5 is exposed to the outside when it is fixed by sewing, for example. The adhesive is the thermal adhesive layer 43. At the time of bonding, heat and pressure are applied from the stacking direction (heat pressing) to melt the heat adhesive layer 43 and bond it to the upper and lower embroidery sheets 4.

Hereinafter, the embroidery sheet 4A is layered on the embroidery sheet 4A in the same manner and heat-pressed. The heat pressing may be performed each time the embroidery sheets 4A are stacked, or may be performed after stacking a plurality of embroidery sheets 4A. Finally, by stacking 5 lower layer embroidery sheets 4A, 1 upper layer embroidery sheet 4B, and 1 upper layer embroidery sheet 4C, the embroidery body 3 is completed, and at the same time, the production of the decorative stud 1 is completed. (See FIG. 2).

As shown in FIG. 8, the decorative stud 1 having the above configuration is attached to a hole previously provided in the school bag. Specifically, eyelet studs 13 are struck at the connecting portion between the hanging lid 11 and the connecting belt 12 (see FIG. 9), and are attached to the eyelet holes 13a formed by the eyelet studs 13. In mounting, first, the shaft portion 22a of the female member 22 is passed through the eyelet hole 13a from the upper side, and the male member 21 is screwed from the lower side. Since the embroidery body 3 is attached to the female member 22, there is also a problem that occurs when the embroidery body 3 is attached to the male member 21 (the embroidery body 3 is sandwiched between the tip of the shaft portion 22a and the seat portion 21b). It can't happen. The embroidery sheet 4 located below the head portion 22c and the seat portion 21b are screwed together until the tip of the shaft portion 22a abuts on the seat portion 21b or the seat portion 21b abuts on the eyelet stud 13 or the school bag to complete the installation. .. In this attached state, as shown in FIG. 8, the embroidery sheet 4 located below the head 22c is interposed between the school bag and the head 22c of the stud body 22 and directly faces the school bag.

In the decorative stud 1 having the above configuration, since the entire head 22c of the stud body 2 is covered with the embroidery body 3, the head 22c cannot be recognized from the outside, and only the embroidery body 3 exists there. It gives the illusion of being as if it were, and gives a soft and gentle impression that is different from conventional studs. Therefore, as shown in FIG. 9, for example, when the hanging lid 11 is embroidered E or the embroidery sheet 4 is attached, a harmonious sense of unity can be given as a whole. Further, since the embroidered body 3 which is a soft member 3 is interposed between the adherend 10 and the head 22c, the head 22c and the adherend 10 do not come into contact with each other, and the decorative stud 1 is attached. It is possible to prevent the adherend 10 from being damaged or left behind.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. For example, the position where the decorative stud 1 is attached is not limited to the connecting portion between the hanging lid 11 and the connecting belt 12, and may be attached to other parts of the hanging lid 11, the side surface 14 of the school bag, and the backpack belt 15 (see FIG. 9). ). Further, although the eyelet stud 13 was used for mounting, it is not always necessary to use it. Further, the stud body 2 is composed of a male member 21 and a female member 22, and the male member 21 and the female member 22 are screwed together so that the decorative stud 1 can be attached and detached, but it cannot be attached and detached. You may. For example, a stud that is fixed by caulking may be used.

Further, the soft member 3 is not limited to the embroidered body, and various materials such as soft resin, rubber, woven fabric, non-woven fabric, and paper that give a soft impression can be adopted. Further, the embroidery body 3 is not limited to a stack of a plurality of embroidery sheets 4, and may be composed of one embroidery sheet 4. The stud body 2 may be made of a hard resin as well as a metal. That is, it may be a hard member.
