Description

  The present invention relates to a cover to be attached to sports shoes, and in particular, to an improvement in the structure thereof.

  In sports shoes, especially short-distance shoes for athletics, the air resistance acting on the instep during running cannot be ignored. For example, it has been found that, for a top athlete on land short distance, the air resistance is maximized when the angle formed by the instep of the shoe and the ground contact surface is about 40 degrees during running. Therefore, in order to reduce the air resistance during running, as shown in Japanese Patent Laid-Open No. 2002-306204, it is possible to eliminate the unevenness of the instep portion of the instep portion by providing a cover on the instep portion of the instep portion. What has been proposed is proposed.

However, in this case, the cover does not cover the front edge of the opening of the shoe mouth, and the front edge of the opening of the shoe mouth is exposed to the outside even after the cover is attached. Further, since the cover is provided with an opening and closing fastener, and the cover surface is not formed completely smoothly, it is easily affected by air resistance. Furthermore, since the fastener portion is not stretchable, the fit when the cover is attached is poor. Further, in the case of a fastener, the entire cover cannot be opened widely, and there is a problem that the operability when tightening a shoe string or belt is poor.
JP 2002-306204 A (see FIG. 1)

  The problem to be solved by the present invention is to provide a cover structure for a sports shoe that can reduce air resistance during running and can improve operability when tightening a shoe string or belt.

  The cover structure of the sports shoe according to the invention of claim 1 is formed integrally with the cover main body covering from the toe portion of the shoe to the front edge of the opening of the wearing mouth through the instep portion, and the opening of the wearing mouth. And a pair of left and right belt-shaped portions extending to the rear end of the shoe along the side edge portions. The cover body is fixed to the peripheral edge of the forefoot part of the sole of the shoe, and the other part of the cover body is provided separately from the sole of the shoe. Moreover, the engaging member which can engage / disengage freely the front-end | tip part of each strip | belt-shaped part is provided.

  According to the first aspect of the present invention, since the cover main body that covers from the toe portion of the shoe to the front edge portion of the mouth opening through the instep portion is provided, the shoe that is most affected by the air resistance during running after the cover is attached. The entire instep will be covered with a cover. Thereby, the air resistance at the time of driving | running | working can be reduced. Moreover, in this case, since the pair of left and right belt-like portions extending to the rear end of the shoe are integrally formed with the cover body, substantially all the region of the upper part of the shoe can be covered with the cover, Thereby, the air resistance during traveling can be further reduced.

  Further, in this case, since the engaging member is provided so that the front end of each belt-like portion can be engaged and disengaged, the cover can be opened and closed by the belt-like portion on the rear end side of the shoe. Thus, it is not necessary to provide a member such as a fastener for opening and closing the cover, and it is possible to form the cover surface with a completely smooth surface without unevenness. As a result, the air resistance during traveling can be further reduced. In addition, by engaging each belt-like portion while pulling the tip of each belt-like portion, the wrinkles and slack of the cover body can be removed to further reduce the air resistance during travel, and the wearer The fit of the cover to the foot can be improved.

  In addition, it is possible to make the cover itself function as the upper part of a shoe by improving the fitting property of the cover. As a result, there is no need to provide an upper part that covers the entire foot as in the past, and a large number of openings are formed in the upper part, or the upper part is configured only from a plurality of belts spaced apart from each other. Thus, the upper part may be constituted by a minimum number of parts, and in this way, the weight of the upper part can be reduced, and consequently the weight of the entire shoe can be reduced.

  In addition, the fixing part of the cover body to the shoe is provided at the peripheral part of the forefoot part of the sole of the shoe, and the other part of the cover body is separated from the sole of the shoe. Thus, when the cover body is opened to the front side of the shoe, the string or belt for tightening the shoe can be exposed, thereby improving the operability when tightening the string or belt.

  In the invention of claim 2, the cover main body is hung on the peripheral part of the front foot part of the sole of the shoe in the region from the heel part of the wearer's foot to the heel part of the toe part. It is fixed.

  In the invention of claim 3, the cover main body is three-dimensionally sewn according to the three-dimensional shape of the foot. In this case, the fit to the foot can be further improved, and a sense of unity with the foot can be realized.

  In the invention of claim 4, the cover body extends upward beyond the front edge of the opening of the shoe mouth. In this case, since the gap between the ankle and the opening front side edge of the shoe mouth can be eliminated, the air resistance during running can be further reduced.

  In the invention of claim 5, the cover main body and the belt-like portion are made of a stretchable material. In this case, the fit to the foot can be further improved without hindering the movement of the foot during running. The stretchability here means at least stretchability in the front-rear direction of the shoe, and preferably means stretchability in two directions, the front-rear direction and the width direction of the shoe.

  In the invention of claim 6, the outer peripheral edge of the cover main body and the belt-like portion is processed by chain stitching. By this “ring stitch”, the stretchability of the outer peripheral edge of the cover body and the belt-like portion is not hindered by sewing, and the stretchability of the cover body and the belt-like portion is maintained. This chain stitch includes a single needle overlock, a two needle overlock, an interlock, a flat two single-sided decoration, a single ring stitch, and the like.

  In the invention of claim 7, the cover main body has a reinforcing material provided along the toe edge periphery of the shoe. Examples of the reinforcing material include attaching urethane resin to the surface of the cover body by bonding, or attaching artificial leather or leather to the surface of the cover body.

  In the invention of claim 8, the engaging member is formed of any one of a hook-and-loop fastener, a hook, a fastener, a buckle and a button.

  In the ninth aspect of the present invention, the first and second belt pieces are respectively fixed to the tips of the belt-like portions, and the first belt piece is formed with an opening into which the second belt piece is inserted. Has been. Then, with the second belt piece inserted into the opening of the first belt piece, the first and second belt pieces can be detachably engaged with the corresponding belt-like portions. ing.

  In this case, on the rear end side of the shoe, with the second belt piece inserted into the opening of the first belt piece, the first and second belt pieces are pulled and engaged with the belt-like portions. As a result, the belt-like members can be easily tightened.

  In the invention of claim 10, a strip-like piece extending upward from the rear edge of the opening of the shoe mouth is provided at the back end of the shoe, and the strip is looped on the back end side of the upper portion. In the state of being folded back, the front end portion of the belt-like piece can be detachably engaged with the rear end of the heel. In this case, the belt-like pieces formed in a loop shape stably hold each belt-like portion between the upper part of the shoe and the belt-like piece. Thereby, the shift | offset | difference of a cover can be prevented.

  As sport shoes to which the present invention is applied, as described in the invention of claim 11, athletics shoes are suitable.

  According to the cover structure of a sports shoe according to the present invention, not only a cover body that covers from the toe portion of the shoe to the front edge of the opening of the shoe mouth through the instep portion is provided, but also a pair of right and left extending to the rear end of the shoe. Since the belt-like portion is integrally formed with the cover main body, substantially all the region of the upper part of the shoe can be covered with the cover, thereby reducing the air resistance during running. In addition, in this case, the fixing portion of the cover body with respect to the shoes is provided on the periphery of the front foot portion of the sole of the shoe, and the other portion of the cover body is separated from the sole of the shoe. When the shoe is opened to the front side of the shoe, the shoe tightening string or belt can be exposed, thereby improving the operability when tightening the string or belt.

In addition, the upper part 3 in which a plurality of apertures 30 are formed and the plurality of belts 4, 5, 6 disposed on the upper part 3 are provided.

  The outsole 2 has a winding portion 21 that rises upward at a shoe midfoot region. The belts 4 and 5 are composed of a pair of left and right belts extending upward from the inner inner side and the outer side. The belts 4 corresponding to the left and right are connected to each other by shoelaces 7 (see FIG. 8). The belt 5 is wound around the rear end side. The belt 6 is a tightening belt with a buckle, for example. A belt-like piece 32 extending upward from an opening rear side edge portion of the mouthpiece 15 is attached to the rear end of the upper portion 3. A hook-and-loop fastener 32 a is attached to the back surface of the strip-shaped piece 32. On the other hand, a hook-and-loop fastener 32b to which the hook-and-loop fastener 32a can be freely engaged and disengaged is fixed to the rear end of the upper portion 3.

  As shown in FIGS. 1 and 2, the cover 10 according to the present invention includes a cover main body 11 that covers from a toe portion of a shoe to an opening front side edge portion 34 (see FIGS. 5 and 8) of a shoe mouth 15 through an instep portion. And a pair of left and right belt-like portions 12 which are formed integrally with the cover body 11 and extend to the rear end of the shoe along the side edges 35 (see FIGS. 5 and 8) of the opening 15 of the footwear 15.

  The cover main body 11 is fixed to the periphery of the front foot portion of the outsole 2 of the shoe, and the other part of the cover main body 11 is provided separately from the outsole 2. Preferably, the cover main body 11 passes from the heel portion of the wearer's foot (the position corresponding to point A in FIG. 1) to the toe portion to the cuboid portion (the position corresponding to point B in FIG. 2). In the area to which it reaches, it is suspended and fixed to the peripheral part of the front foot part of the outsole 2 of the shoe. The cover body 11 extends upward beyond the opening front side edge 34 of the shoe mouth 15. In other words, the upper edge 11 a of the cover main body 11 is disposed above the opening front edge 34 of the wear mouth 15.

  The cover body 11 is three-dimensionally sewn according to the three-dimensional shape of the foot. In the example shown in FIGS. 1 and 2, the cover main body 11 includes an outer side member that is arranged on the outer side and extends to the upper part of the instep, and an inner side member that is arranged on the inner side and extends to the upper part of the instep. And these outer side members and inner side members are sewn in the upper part of the instep. In this case, it is possible to easily follow the three-dimensional shape of the foot, and the number of seam portions can be reduced. Moreover, it is preferable that the cover main body 11 and the strip | belt-shaped part 12 are comprised from the raw material which has a stretching property. The stretchability here means at least stretchability in the front-rear direction of the shoe, and preferably means stretchability in two directions, the front-rear direction and the width direction of the shoe.

  It is preferable that the outer peripheral edge portion of the cover body 11 and the belt-like portion 12 (and the sewing portion of the upper part of the instep of the cover body 11) be “ring stitched” by an overlock sewing machine. By this “ring stitch”, the stretchability of the outer peripheral edge of the cover main body 11 and the belt-like portion 12 is not hindered by sewing, and the stretchability of the cover main body 11 and the belt-like portion 12 is maintained.

  The cover main body 11 has a reinforcing member 18 provided along the toe portion periphery of the shoe 1. Examples of the reinforcing material 18 include, for example, coating the surface of the cover body with urethane resin by bonding, or bonding artificial leather or leather to the surface of the cover body.

  As clearly shown in FIG. 8, the first and second belt pieces 13 and 14 are fixed to the front ends of the belt-like portions 12, respectively. An opening 13a into which the belt piece 14 is inserted is formed. A hook-and-loop fastener 13 b is fixed to the back surface of the first belt piece 13. Similarly, a hook-and-loop fastener 14 b is fixed to the back surface of the second belt piece 14. On the other hand, a hook-and-loop fastener 12a (see FIG. 6) to which the hook-and-loop fasteners 13b and 14b of the first and second belt pieces 13 and 14 can be detachably engaged is fixed to the surface of each band-like portion 12. Yes.

Next, the function and effect of this embodiment will be described.
As described above, according to the present embodiment, the cover body 11 that covers from the toe portion of the shoe 1 through the instep portion to the opening front side edge portion 34 of the mouthpiece 15 is provided. The entire instep of the shoe 1 affected by the air resistance is covered with the cover 10. Thereby, the air resistance at the time of driving | running | working can be reduced. In addition, in this case, since the pair of left and right belt-like portions 12 extending to the rear end of the shoe 1 are integrally formed with the cover body 11, substantially all the region of the upper portion of the shoe 1 is covered with the cover 10. Thus, the air resistance during traveling can be further reduced.

  Furthermore, in this case, since the cover body 11 extends upward beyond the opening front side edge 34 of the shoe mouth 15 of the shoe 1, the ankle and the opening front side edge 34 of the shoe mouth 15 of the shoe 1 are connected. The gap can be eliminated, and thereby the air resistance during running can be further reduced.

  In addition, since the cover body 11 is three-dimensionally sewn in accordance with the three-dimensional shape of the foot, the fit to the foot can be further improved, and a sense of unity with the foot can be realized. Furthermore, since the cover main body 11 and the belt-shaped part 12 are comprised from the raw material which has a stretching property, the fitting property with respect to a leg can be improved further, without inhibiting the movement of the leg at the time of driving | running | working. At this time, the outer peripheral edge portions of the cover body 11 and the belt-like portion 12 are stitched by the overlock sewing machine, so that the stretchability of the outer peripheral edge portions of the cover main body 11 and the belt-like portion 12 is not hindered by sewing. The stretchability of the cover body 11 and the belt-like portion 12 is maintained.

  Furthermore, according to the present embodiment, the first and second belt pieces 13 and 14 fixed to the tips of the belt-like portions 12 are provided in the belt-like portions 12 so as to be detachable. Can be performed by the belt-like portion 12 via the first and second belt pieces 13 and 14 on the heel rear end side of the shoe 1, thereby eliminating the need to provide the cover 10 with a member such as a fastener for opening and closing. It is possible to form the cover surface with a completely smooth surface without unevenness. As a result, the air resistance during traveling can be further reduced.

  Further, when the belt pieces 13 and 14 of the belt-like portions 12 are engaged, the belt pieces 13 and 14 are engaged while being pulled, so that wrinkles and slack of the cover main body 11 are removed and air resistance during traveling is obtained. Can be further reduced, and the fit of the cover to the wearer's foot can be improved.

  In addition, it is possible to make the cover 10 itself function as an upper part of the shoe 1 by improving the fit of the cover 10. Accordingly, it is not necessary to provide a cover portion that covers the entire foot as in the prior art, and a plurality of apertures 30 are formed in the cover portion 3 as shown in the present embodiment, or a plurality of belts that are spaced apart from each other. By configuring the upper part only from the upper part, the upper part can be formed from the minimum parts, and the weight of the upper part can be reduced in this way, and thus the weight of the entire shoe can be reduced.

  Further, the fixing portion of the cover body 11 to the shoe 1 is provided on the front foot peripheral portion of the outsole 2 of the shoe 1, and the other part of the cover body 11 is separated from the outsole 2 of the shoe 1. When the first and second belt pieces 13 and 14 are disengaged and the cover body 11 is opened to the front side of the shoe (see FIG. 8), the string 7 and the belt 6 for tightening the shoe 1 are exposed. Thus, the operability when tightening the string 7 or the belt 6 can be improved.

  Next, when the cover 10 is closed after the cover 10 is fully opened as shown in FIG. 8, that is, when the cover 10 is attached to the shoe 1, as shown in FIGS. While the belt-like piece 32 is disengaged, each belt-like portion 12 is wound around the shoe rear end side of the shoe 1, and the second hole is formed in the opening 13 a of the first belt piece 13 on the shoe rear end side. After the belt piece 14 is inserted, the hook-and-loop fasteners 13b and 14b on the back surfaces of the belt pieces 13 and 14 are engaged with the hook-and-loop fasteners 12a of the belt-like portions 12 respectively.

  Next, the belt-like piece 32 is folded back toward the rear end of the heel, and the strip-like piece 32 is engaged with the hook-and-loop fastener 32b on the heel rear end side of the upper portion 3 (see FIGS. 3 and 4). Accordingly, the first and second belts 13 and 14 are stably clamped between the upper portion 3 and the belt-like piece 32. As a result, the cover 10 can be prevented from shifting while the cover 10 is attached.

  In the embodiment, the hook-and-loop fastener 13b is used to detachably engage the first and second belt pieces 13 and 14 fixed to the tips of the belt-like portions 12 of the cover body 11 with the belt-like portions 12. 14b is used, but as such an engaging member, a hook, a fastener, a buckle or a button may be used in addition to the hook-and-loop fastener. Similarly, as an engaging member for detachably engaging the strip-like piece 32 extending upward from the rear edge of the opening of the shoe mouth 15 of the shoe 1 to the rear end of the upper portion 3, other than a hook-and-loop fastener. May be used.

  As the shoes to which the cover structure according to the present invention is applied, the above-described athletics shoes are suitable, but the present invention is also applicable to sports shoes such as basketball and volleyball.
