Description

  The present invention relates to a training shoe with a finger crotch having a finger crotch between a thumb part and a four finger part.

  An underground tabi having a crotch between a thumb part and a four-finger part has various advantages, and is still used for a job. The advantage of the finger crotch is that it is easy to put force on the free thumb part relative to the other four-finger parts, so the gripping force (grip force) by the sole increases, so that you can walk safely even on unstable scaffolds A point can be mentioned. In recent years, in addition to the gripping force, it has been found that easy to apply force to the thumb part leads to strengthening of muscle strength from foot to leg, and training shoes with finger crotch (training shoes with finger crotch) have been proposed. It is becoming. The finger crotch of this training shoe with a finger crotch is formed, for example, by suspending a cracked portion of the upper part in a cracked portion of the shoe sole.

  The training shoes with a finger crotch found in Patent Documents 1 to 4 have a configuration in which a finger crotch is formed in a conventional training shoe that has been conventionally seen. On the other hand, the training shoe with a finger crotch shown in Patent Document 5 has a structure in which an underground socks are brought close to the training shoe. The difference between the two is that the upper and the sole are continuous as in a normal training shoe (Patent Literature 1 to Patent Literature 4), or the upper and the sole each have a cracked portion (Patent Literature 5). ) Is the difference. The former cannot visually recognize the presence of the finger crotch from the appearance, but the latter can visually recognize the presence of the finger crotch even when viewed from the front, the plane, or the bottom.

  The training shoes with finger crotch shown in Patent Document 1 to Patent Document 4 can look like a normal training shoe by providing a finger crotch inside, but can increase the degree of freedom of the thumb part with respect to the four finger parts. Therefore, it is difficult to obtain the advantage of having a finger crotch. On the other hand, the training shoes with a finger crotch shown in Patent Document 5 can sufficiently obtain the advantages of having a finger crotch by clearly dividing the finger crotch into a thumb part and a four finger part. However, it seemed uncomfortable as if you were wearing an underground socks, and resisted wearing and hindered popularization. Therefore, as a training shoe with a finger crotch, we studied to achieve an appearance that does not give a sense of incongruity as if wearing an underground socks while adopting the configuration of Patent Document 5 that sufficiently obtains the advantages of having a finger crotch. .

Was developed result of the examination is, each composed instep and sole having a cracked portion divided into a thumb portion and four finger portions, the finger crotch forming crowded hanging under the upper to the sole, vamp In a training shoe with a finger crotch that covers the cracked part of the upper part with a tip cover so that the cracked part cannot be visually recognized , the tip cover is turned from the upper part of the cracked part of the upper part to the front and is folded into the lower surface. It is a training shoe with a finger crotch having a section . The front cover covers the cracked part of the upper cover, hides the finger crotch, eliminates the discomfort as if wearing an underground socks, and does not give resistance to wearing. Further, since the finger crotch is only covered with the tip, the advantage of having the finger crotch can be sufficiently obtained without hindering the degree of freedom of the thumb part.

  The front cover only needs to hide at least the cracked portion of the upper cover, but the front cover may teach the presence of the finger crotch. Therefore, the front cover has a size ranging from the thumb part that covers the cracked part of the upper part to the four-finger part. The edge that crosses the upper part is sewn to the upper part, and the remaining edge part is attached to the shoe sole together with the upper part. It is good to have a configuration to suspend. In other words, the thumb part including the crotch part and the part of the upper part that forms the four-finger part are housed in the front cover, so that the crotch is not visually recognized, and the degree of freedom of the thumb part, Secure up to the degree of freedom. In addition, the tip cover of this size also acts as a protective cloth for protecting the toe, like the conventional training shoes, and is in harmony with the other parts and does not impair the design as a training shoe.

When the front cover is put on the cracked part of the upper cover, the front cover is rolled over the thumb part and the four finger parts by scooping the cracked part of the upper part, but the lower edge of the cracked part is hung on the shoe sole. The finger crotch formed by the split parts of the upper and the shoe sole becomes a space opened downward, and there is a possibility that pebbles and the like may enter the space. Therefore, before the can when the configuration having the protrusion Tsukomi portion from the upper surface of the cracking portion of the vamp are written Ri folded on the bottom surface by turning the front. As a result, the finger crotch becomes a closed space with the upper surface side covered by the front cover and the lower surface side closed by the protruding suspending portion, and the possibility of pebbles and the like entering the finger crotch can be eliminated. Here, there are many shoe sole patterns in which the thumb part and the four finger part are separated, so just touching the bottom side of the finger crotch, you can feel the presence of the finger crotch from the shoe sole side. You can not let it.

  As described above, a thick coat or cloth can be used as a protective cloth for protecting the toe, as described above, but the thin front cover is thin from the viewpoint of ensuring the freedom of the thumb part and the four-finger part. It is desirable. In this case, if the tip cover is loosened and falls into the finger crotch, the meaning of hiding the finger crotch with the tip cover is lost. Therefore, it is preferable to attach a step-preventing cloth that is directed to the upper part from the thumb part that covers the cracked part of the upper part to the four-finger part. That is, while using a thin tip covering, only the portion that may fall into the finger crotch is made thick by adding a step prevention cloth so that the tip covering does not fall into the finger crotch.

  The present invention provides a training shoe with a finger crotch that has a finger crotch that clearly separates a thumb part and a four-finger part and cannot visually recognize the finger crotch. Accordingly, it is possible to promote the popularization of training shoes with finger crotches that do not give a sense of incongruity as if wearing an underground socks, while sufficiently obtaining the advantages of having finger crotches. If the tip cover is sized to hide the thumb part and the four finger part in addition to the finger crotch, the degree of freedom of the thumb part and the four finger part can be secured, and the appearance uses the tip cover as a protective cloth, and The design can also be inferior to conventional training shoes. In addition, when the tip cover covers the lower surface side of the finger crotch with the protruding suspending portion, the presence of the finger crotch can be hidden even when viewed from the shoe sole side, and further, a step prevention cloth is attached to the finger crotch. Can be avoided, and the presence of the crotch can be hidden. As described above, the present invention has an effect of hiding only the finger crotch without impairing the advantage of having the finger crotch in a training shoe with a finger crotch where the thumb part and the four finger part are clearly separated. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a training shoe 1 with a finger crotch to which the present invention is applied, FIG. 2 is a perspective view showing a state in which an edge portion 141 of a front cover 14 is sewn on an upper 12, and FIG. FIG. 4 is a partial bottom view of the state before suspending the tip cover 14 from the inside of the instep 12 (not shown), and FIG. 5 is a projection. FIG. 6 is a partial bottom view showing the state in which the hanging part 143 is folded back (illustration of the mold 2 is omitted), and FIG. 6 is a partial sectional view showing the state in which the protruding hanging part 143 is folded back (cut by the finger crotch 11; 2 is omitted). The training shoe 1 with a finger crotch in this example is for the right foot, and the other parts except for the toe cover 14 are the same as the training shoes of the same type in the past. For example, the upper 12 has a configuration in which a thin fabric for interior is layered on a mesh material. The shoe sole 13 is composed of an EVA bottom.

  As shown in FIG. 1, the training shoe with finger crotch 1 includes an upper 12 having a split portion 121, 131 and a sole 13 that are divided into a thumb portion 122 and a four-finger portion 123, and the upper 12 according to the split portion 121, 131. The finger crotch 11 is formed by suspending the shoe on the shoe sole 13. The cracked portion 131 of the shoe sole 13 is not concealed, but the cracked portion 121 of the upper 12 is covered with the tip cover 14 so that it cannot be visually recognized. Thereby, the training shoe 1 with a finger crotch of the present invention eliminates a sense of incongruity as if wearing an underground socks in appearance and does not give resistance to wearing. Further, the tip 14 only covers the toe portion of the upper 12 including the finger crotch 11, the degree of freedom of the thumb portion 122 is not hindered, and the advantage of having the finger crotch 11 is not impaired.

  The front cover 14 is a U-shaped skin material in plan view that extends from the thumb part 122 to the four-finger part 123 that crawls the cracked part 121 of the upper part 12, and an inner edge 141 that crosses the upper part 12 has an upper edge 12. Then, an adhesive is applied along the remaining outer edge 142 (see FIG. 2), and is hung on the shoe sole 13 together with the upper 12. Specific examples of the skin material of the tip coat 14 include sheep skin, pig skin and cow skin. The tip cover 14 of the present example is configured not to make the finger crotch 11 visible from the appearance by covering the toe part of the upper part 12 forming the thumb part 122 and the four finger part 123 including the finger crotch 11, as well as the thumb part 122. In addition to the degree of freedom, the degree of freedom of the four finger part 123 is secured. In addition, the toe cover 14 of this example also works as a protective cloth for protecting the toe, and is in harmony with the other parts and does not impair the design as a training shoe.

  In addition, as described later, the tip cover 14 of this example folds the protruding hanging portion 143 so as to surround the finger crotch 11 so that the presence of the finger crotch 11 is not felt even when viewed from the shoe sole 13. A step-preventing cloth 144 that is directed to the upper 12 from the thumb portion 122 to the four-finger portion 123 that holds the cracked portion 121 of the upper 12 is attached to the inside (see FIGS. 2 to 5). The protruding suspending portion 143 is a portion that continuously protrudes from the tip cover 14, forms a closed space together with the finger crotch 11 and the tip cover 14, and eliminates the possibility of pebbles and the like entering the space. Further, the step prevention cloth 144 is made of a T-shaped canvas that is separate from the front cover 14 so that the front cover 14 does not fall into the finger crotch 11 and the finger crotch 11 exists due to the bending of the front cover 14 or the like. Try not to be realized.

  The manufacturing procedure of the training shoe 1 with finger crotch of this example will be described. As shown in FIG. 2, the upper 12 is formed by sewing or adhering various skin materials or cloth materials to each other according to the mold 2. The feature of the upper 12 of this example is that, unlike the conventional training shoes of the same type, the toe part has a cracked part 121, the toe part is divided into a thumb part 122 and a four-finger part 123. The finger crotch 11 is formed by suspending it on the shoe sole 13 having the same. The front cover 14 is a state in which a step-preventing cloth 144 is attached to a portion of the back surface (the inner surface that cannot be seen from the outside) that covers the finger crotch 11, and an inner edge 141 crossing the upper 12 is turned over to the upper 12 Sewing in a state where the back surface is the top surface. The protruding hanging part 143 protrudes rearward and upward.

  After the tip 14 is sewn to the upper 12 and the adhesive is applied along the remaining outer edge 142 that has not been sewn, the entire tip 14 is removed as shown in FIGS. The tip cover 14 is put on the finger crotch 11, the thumb portion 122, and the four finger portion 123 by turning over. The tip 14 covers the finger crotch 11 and covers the thumb part 122 and the four finger part 123 in a U shape in plan view, and hides the finger crotch 11. At this time, since the step prevention cloth 144 is placed between the upper 12 and the front cover 14 by scooping the finger crotch 11, there is no possibility that the front cover 14 falls into the finger crotch 11 (see FIG. 3). Further, the edge portion 141, 142 is sewn or stuck to the upper 12 respectively, but most of the front cover 14 is simply overlapped with the upper 12, so that the thumb portion 122 and the four finger portion 123 are It can be moved freely within the range surrounded by the tip 14. At this time, the protruding suspending portion 143 protrudes forward or downward.

  The upper 12 and the front 14 are coated with adhesive on the lower peripheral edge and hung from the shoe sole 13 (see FIG. 1). At this time, as shown in FIGS. 5 and 6, the projecting hanging portion 143 projecting forward or downward is folded back toward the rear, and the upper 12, the front covering 14, and the projecting hanging portion 143. A finger crotch 11 is formed in a closed space surrounded by. That is, the front cover 14 of this example hides the upper surface side of the finger crotch 11, and also conceals the lower surface side of the finger crotch 11 by the folded projecting suspending part 143 so that the presence of the finger crotch 11 cannot be visually recognized from the appearance. Yes. The protruding hanging part 143 does not hide the cracked part 131 of the shoe sole 13, but the pattern of the shoe sole 13 may be divided into a thumb part 122 and a four-finger part 123. If even the lower surface side of the finger crotch 11 can be blocked by the portion 143, the presence of the finger crotch 11 can be prevented from being felt even when viewed from the shoe sole 13 side.
