The bottom view of the jumping shoes concerning the modification of the embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

The jumping shoes according to the present embodiment belong to a so-called half-shoe that is worn exclusively during gymnastics such as rhythmic gymnastics in which a toe is covered and a rubber string as an elastic body is fastened on an instep and a heel.

In the jumping shoe, an upper surface portion 110 made of natural leather having a soft and stretchable shoe body 100 and a lower surface portion 120 made of natural leather having a soft and stretchable shape have openings 130 at one end portions 110a and 120a, respectively. Each edge 110b, 120b is formed into a bag shape by sewing together with a seam allowance of 2.5 mm to form. The flat shape of the shoe body 100 is that the half on the thumb side and the half on the little finger side of the shoe body 100 are asymmetrical, and the thumb side is compared to the little finger side so that the shoe body 100 can softly wrap the entire toes. It is greatly formed. Further, the width W110 (see FIG. 5) of the upper surface portion 110 is formed to be larger than the width W120 (see FIG. 6) of the lower surface portion 120 so that W110> W120. The seam allowance is set to 2.5 mm, which is suitable considering as much as possible the reduction in load on the wearer's foot, particularly the toe, due to the seam. However, the seam allowance is not strictly limited to this 2.5 mm, and it is a matter of course that the shoe main body 100 can be manufactured with a slight numerical range.

The upper surface portion 110 and the lower surface portion 120 are made of natural leather with a thickness of about 0.4 mm that is soft and stretchable as natural leather. Since it is suitable in terms of easiness and easiness of sewing, it is the thickness, and is not limited to the thickness as long as it has an equivalent function. Although artificial material having the same function as natural cow leather may be used, natural cow leather is advantageous and practical in terms of cost and softness of seams at the toe portion. Natural pig leather and deer leather may be used, but since natural pig leather is thick, processing to make it thin and soft is necessary. Not suitable. Although natural deer leather is soft, it is easy to tear and has difficulty in durability and is expensive. Therefore, at present, natural cowhide is preferable because it is excellent in durability and inexpensive in terms of cost and has the merit that its performance varies depending on the processing method.

Further, the front side of the natural cowhide is the upper part of the upper surface part 110, and the upper side of the upper surface part 110 has a good appearance and is difficult to adhere dirt, and can be easily removed even if dirt is attached. It is. Moreover, the back side of natural cowhide is made the lower part of the lower surface part 120, and it is comprised so that a function may be exhibited as a slipper.

An insole portion 140 having a deodorizing function and a drying function, which is made of a fabric having a stretchability and a linearly blended deodorant component, is attached to the upper portion of the lower surface portion 120 with a rubber glue adhesive. Further, the insole portion 140 attached to the lower surface portion 120 by adhesion of rubber glue is V-shaped from one end side to the other end side of the lower surface portion 120 (from the left side to the right side in FIGS. 3 and 6). It is sewed to the lower surface part 120 through the shape-like seam 150. The V-shaped seam 150 is formed such that when the shoe body 100 is attached to a foot, the insole portion 140 is formed on the lower surface portion against the force generated by the movement of the wearer with respect to the insole portion 140 and the lower surface portion 120. It functions so that it can hold the state firmly attached to 120.

Further, a cover 160 is sewn to the opening 130 on the upper surface 110 side of the shoe main body 100 through a seam 162 by gathering. The cover 160 is made of a two-way fabric having excellent extensibility and is designed. Moreover, this cover 160 is comprised so that the site | part located in the opening part 130 of the cyclic | annular rubber string (1st elastic body) 170 mentioned later may be coat | covered.

The annular rubber strap 170 is sewn to a part of the opening 130 on the upper surface 110 side of the shoe main body 100 by gathering. Thus, the entire portion located in the opening 130 is configured to be covered with the cover 160 as described above. The rubber strap 170 may be configured to be sewn via the seams 172 and 174 by gathering as shown in FIG.

Also, an annular rubber string (second elastic body) 180 is provided inside the opening 130 on the lower surface 120 side of the shoe body 100 by being sewn through the seams 182 and 184 by gathering. ing.

Furthermore, a tag 190 having a deodorizing function is attached to the upper surface side of the insole portion 140 of the shoe main body 100. The tag 190 is attached by sewing both end portions in the longitudinal direction to the insole portion 140.

An example of the manufacturing method of the jumping shoe will be described with reference to FIGS.

First, the insole portion 140 is bonded to the upper side of the lower surface portion 120 with rubber paste (step S710 in FIG. 7). Next, by providing a V-shaped seam 150 with a sewing machine from one end 120a to the other end of the lower surface 120 (from the left side to the right side in FIG. 6), the insole portion 140 is The portion 120 is sewn (step S720 in FIG. 7). Subsequently, the cover 160 is sewn to the part forming the opening 130 on the upper surface part 110 side with a sewing machine through the seam 162 by gathering (step S730 in FIG. 7). Thereafter, the rubber string 170 is sewn to the part where the opening 130 on the upper surface part 110 side is formed by gathering and sewing (step S740 in FIG. 7). Thus, the upper surface portion 110 and the lower surface portion 120 are sewn into a bag shape by stitching the respective edge portions 110b and 120b with a sewing machine at a sewing margin of 2.5 mm so as to form the opening portion 130 at the respective one end portions 110a and 120a. Thus, the shoe main body 100 is produced (step S750 in FIG. 7). The completed shoe body 100 is sewn to the opening 130 on the lower surface portion 120 side by providing the seam 182 and 184 with the sewing machine by gathering the rubber string 180 (step S760 in FIG. 7). Finally, the tag 190 is sewn to the upper part of the insole portion 140 at both ends thereof (step S770 in FIG. 7). Thereby, the jumping shoes of this embodiment are completed.

In the jumping shoe manufacturing process, the cover 160 and the rubber string 170 are attached to the opening 140 in the order of attaching the rubber string 170 after the cover 160 is attached. As shown, the cover 160 may be attached after the rubber strap 170 is attached.

That is, first, the insole portion 140 is bonded to the upper side of the lower surface portion 120 with rubber paste (step S810 in FIG. 8). Next, by providing a V-shaped seam 150 with a sewing machine from one end 120a to the other end of the lower surface 120 (from the left side to the right side in FIG. 6), the insole portion 140 is The portion 120 is sewn (step S820 in FIG. 8). Subsequently, the rubber string 170 is sewn to the part where the opening 130 on the upper surface part 110 side is gathered with a sewing machine through the seams 172 and 174 by gathering (step S830 in FIG. 8). Thereafter, the cover 160 is sewn to the part sewn in the opening 130 of the rubber cord 170 by gathering by providing a seam 162 with a sewing machine on the upper surface part 110 so as to cover the whole part (see FIG. 8 step S840). Thus, the upper surface portion 110 and the lower surface portion 120 are sewn into a bag shape by stitching the respective edge portions 110b and 120b with a sewing machine at a sewing margin of 2.5 mm so as to form the opening portion 130 at the respective one end portions 110a and 120a. Thus, the shoe main body 100 is produced (step S850 in FIG. 8). The completed shoe body 100 is sewn to the opening 130 on the lower surface 120 side by providing the seam 182 and 184 with a sewing machine by gathering the rubber strap 180 (step S860 in FIG. 8). Finally, the tag 190 is sewed on both ends of the insole portion 140 (step S870 in FIG. 8). Thereby, the jumping shoes of this embodiment are completed.

According to the above-described embodiment, the bag-like shoe main body 100 is formed of soft stretchable natural cowhide, the rubber straps 170 and 180 are sewn to the shoe main body 100 by gathering, and the opening on the upper surface portion 110 side. The rubber strap 170 sewn on 130 is covered with the cover 160, so that the function of the natural cowhide is fully utilized, it has excellent exercise characteristics, holdability and wearing feeling, and high performance, competition and practice. It can contribute to stability and safety, and can provide high durability. In addition, it is possible to solve the problem of feeling uncomfortable wearing shoes, pain, or hurting the skin of the upper. Also, the half on the thumb side and the half on the little finger side of the shoe body 100 are asymmetrical, and the shoe body 100 is formed larger on the thumb side than the little finger side so that the entire foot finger is wrapped softly. Since no force is generated in the direction of the inner crotch on the wearer's foot as shown in FIG. 5, there is no additional load on the wearer, and in addition, a V-shaped seam 150 is provided on the lower surface portion 120. The attachment power of the insole portion 140 to the lower surface portion 120 is remarkably improved, and as a result, it is possible to concentrate on acting, competition, practice and the like. Moreover, since the cover 160 is designed, the aesthetic appearance is improved and shoes with various industrial designs can be provided. In addition, since the insole portion 140 attached to the lower surface portion 120 absorbs moisture such as odor and sweat, it has a hygienic practical effect of being excellent in deodorizing properties and drying properties. . Moreover, the lower surface side of the shoe body 100 has a double structure with the insole portion 140 and is resistant to the effects of friction, sweat, etc., and is less likely to peel off than conventional insoles attached by thermal welding. The floor is in close contact with the foot and is difficult to slip. In addition, by using a soft and stretchable material with a thickness of about 0.4 mm, it is possible to make a shape close to the foot, hold an appropriate hold on the foot, and is excellent in wearing feeling and fitting feeling. is there. Even if the seam hits the toe, there is no unnecessary pressure and pressure as compared with conventional ones due to the characteristics of natural cowhide, and a soft feel can be obtained. And since the front side of the natural leather is the upper part of the upper surface part 110, the upper side of the upper surface part 110 looks good and does not easily get dirt, and even if dirt is attached, it can be easily removed. Moreover, since the back side of the natural leather is made to be the lower part of the lower surface part 120, it functions as an anti-slip and has a practical effect. Further, since the rubber string 180 is attached to the upper side of the lower surface part 120 by gathering so as to be positioned inside the opening 130 and the cover 160 is attached to the opening 130 by gathering, the wearer's Appropriate frictional force is generated on the soles and ankles, and the shoe main body 100 can be prevented from being inadvertently removed during the gymnastic performance.
