Description

[Technical Field]

[0001] The present invention relates to a shoe component used in a shoe upper and a shoe having an upper using the same. [Background technology]

[0002] Shoes have an upper that covers the wearer's foot and a sole that covers the sole of the wearer's foot. When the wearer kicks off while walking or running, the MP joint of the wearer's foot flexes, causing the wearer's foot to try to slip out of the upper. Therefore, the shoe upper is required to fit the wearer's foot and prevent the wearer's foot from slipping out even when the MP joint of the wearer's foot flexes during kicking.

[0003] To improve the fit of the upper to the wearer's foot, a lace-up fitting structure is provided on the upper. Patent Document 1 discloses a shoe with eyelets on a side panel that is not surface-bonded to the exterior material of the main upper. The shoe disclosed in Patent Document 1 allows the wearer to choose whether to fit the side panel to the wearer's foot, or to fit both the side panel and the main upper, so the fit can be adjusted to suit the wearer's preference. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5444558 Summary of the Invention [Problem to be solved by the invention]

[0005] Shoes with a lace-up fitting structure have a tongue that covers the instep of the wearer's foot. The shoes disclosed in Patent Document 1 do not allow adjustment of the fit of the tongue to the instep of the wearer's foot, so there is room for further improvement in the fit to the wearer's foot.

[0006] The present invention has been made in view of the above, and has as its object to provide a shoe component that can form an upper that fits closely to the wearer's foot. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems and achieve the object, the shoe component of the present invention includes a tongue that covers the instep of a wearer's foot, an inner wing that covers the wearer's medial midfoot portion, and an outer wing that covers the wearer's lateral midfoot portion. Tongue eyelets for passing shoelaces are provided in at least one of the inner tongue portion having a portion of the tongue that is medial to the center in the foot width direction and the inner wing, and the outer tongue portion having a portion of the tongue that is lateral to the center in the foot width direction and the outer wing. [Effects of the Invention]

[0008] The shoe component according to the present invention has the effect of forming an upper that fits closely to the wearer's foot. [Brief explanation of the drawings]

[0010] Hereinafter, embodiments of shoe components and shoes according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. In the embodiments shown below, the same or common parts are designated by the same reference numerals, and their description will not be repeated.

[0011] In the embodiments described below, the direction in which the heel center axis, which is a perpendicular line passing through the heel center of the sole when the shoe is viewed in a plan view, extends is referred to as the front-to-rear direction, and the direction perpendicular to the front-to-rear direction when the shoe is viewed in a plan view is referred to as the foot width direction.

[0012] In addition, within the front-to-rear direction, the direction from the heel to the toe in the shoe is referred to as the front, and within the front-to-rear direction, the direction from the toe to the heel in the shoe is referred to as the rear.

[0013] The side of the foot that is closest to the midline in the anatomical orthogonal position is called the medial side, and the side of the foot that is opposite the midline in the anatomical orthogonal position is called the lateral side. In other words, the side closest to the midline in the anatomical orthogonal position is called the medial side, and the side farthest from the midline in the anatomical orthogonal position is called the lateral side.

[0014] Furthermore, unless otherwise specified, the height direction means the direction perpendicular to both the front-to-back direction and the foot width direction, and the thickness means the dimension in the height direction unless otherwise specified.

[0015] (Embodiment 1) 1 is a perspective view of a shoe according to a first embodiment of the present invention. Shoe 50 includes upper 1 that covers the wearer's foot and sole 2 that covers the sole of the wearer's foot. Upper 1 includes main upper 11 that covers the wearer's forefoot, midfoot, and heel, and shoe component 12A that covers the wearer's instep.

[0016] The main upper 11 has a first opening 1A through which the wearer's foot passes and a second opening 1B connected to the first opening 1A in front of the first opening 1A. The main upper 11 has upper eyelets 111 on the edge of the second opening 1B through which the shoelaces 3 pass. The main upper 11 also has an insole (not shown).

[0017] 2 is a plan view of a shoe component according to the first embodiment. The shoe component 12A includes a tongue 121 that covers the instep of the wearer, an inner wing 122 that covers the medial midfoot portion of the wearer, and an outer wing 123 that covers the lateral midfoot portion of the wearer. The inner wing 122 and a portion of the tongue 121 that is closer to the medial side of the center in the foot width direction constitute the inner tongue portion 21. The inner wing 122 is a tongue-shaped member that extends from the tongue 121 toward the medial side of the foot width direction. The outer wing 123 and a portion of the tongue 121 that is closer to the lateral side of the center in the foot width direction constitute the outer tongue portion 22. The outer wing 123 is a tongue-shaped member that extends from the tongue 121 toward the lateral side of the foot width direction. The inner tongue portion 21 and the outer tongue portion 22 are provided with tongue eyelets 23 through which shoelaces 3 are passed. The shoe component 12A may have the inner wing 122 and the outer wing 123 seamlessly connected to the tongue 121, or the inner wing 122 and the outer wing 123 may be separate components sewn to the tongue 121.

[0018] The tongue eyelets 23 are provided in a portion of the tongue 121 closer to the medial side than the center in the foot width direction, and in a portion of the tongue 121 closer to the lateral side than the center in the foot width direction. Two tongue eyelets 23 are provided in the medial tongue portion 21 and one in the lateral tongue portion 22. The tongue eyelets 23 formed in the medial tongue portion 21 and the tongue eyelets 23 formed in the lateral tongue portion 22 are arranged alternately in the front-to-rear direction. The shoe component 12A is formed of a material having elasticity different from that of the main upper 11.

[0019] The tongue 121, inner wing 122, and outer wing 123 each have an outer outer material that forms the outer surface and an inner outer material that forms the inner surface. The tongue eyelet 23 is formed by a portion of the outer outer material sandwiched between slits 24 formed in parallel in the outer outer material. In the tongue eyelet 23, the shoelace 3 is pulled between the outer outer material and the inner outer material through one slit 24, and the shoelace 3 is pulled out from between the outer outer material and the inner outer material through the other slit 24. By forming a portion of the outer outer material of the shoe component 12A as the tongue eyelet 23, a more part-less structure can be achieved compared to a structure in which the tongue eyelet 23 is formed by attaching a ring-shaped part to the outer outer material. However, the tongue eyelet 23 is not limited to the portion of the outer outer material sandwiched between the slits 24 formed in parallel. In other words, the tongue eyelet 23 may be formed by attaching a ring-shaped part to each of the inner tongue portion 21 and the outer tongue portion 22. The slits 24 extend in the foot width direction. By making the slits 24 extend in the foot width direction, it is possible to reduce resistance when threading the shoelace 3 through the tongue eyelet 23. The slits 24 may also extend in the front-to-rear direction.

[0020] 3 is a top view of a shoe according to the first embodiment. As described above, upper eyelets 111 are provided at the edge of second opening 1B of main upper 11, but upper eyelets 111 are not provided at the medial edge of second opening 1B, which is located at the same longitudinal position as tongue eyelets 23 provided in medial tongue portion 21. Furthermore, upper eyelets 111 are not provided at the lateral edge of second opening 1B, which is located at the same longitudinal position as tongue eyelets 23 provided in lateral tongue portion 22. Shoelace 3 is threaded alternately through tongue eyelets 23 provided in medial tongue portion 21 and tongue eyelets 23 provided in lateral tongue portion 22, and then threaded through upper eyelets 111. Here, if the shoelace 3 is divided into two parts starting from the midpoint between the part that passes through the forward-most upper eyelet 111 on the inner side of the foot and the part that passes through the forward-most upper eyelet 111 on the outer side of the foot, the half that passes only through the upper eyelet 111 is called the first part 31, and the half that passes through the upper eyelet 111 and the tongue eyelet 23 is called the second part 32.

[0021] FIG. 4 is a diagram showing the fixed state of the shoe component, main upper, and sole according to the first embodiment. The front edge of the tongue 121 of the shoe component 12A is connected to the front edge of the second opening 1B of the main upper 11 by a method such as sewing or welding. The tip of the outer wing 123 of the shoe component 12A is sewn to the lower end of the midfoot portion of the main upper 11 and the insole. Part A in FIG. 4 is the sewing location between the front edge of the tongue 121 of the shoe component 12A and the front edge of the second opening 1B of the main upper 11. Part B in FIG. 4 is the sewing location between the tip of the outer wing 123 of the shoe component 12A and the lower end of the midfoot portion and the insole of the main upper 11. Although not shown in FIG. 4, the tip of the inner wing 122 of the shoe component 12A is sewn to the lower end of the midfoot portion of the main upper 11 and the insole. Therefore, the shoe component 12A forms an arch in the width direction of the foot.

[0022] After the wearer puts on the shoe 50, pulling the first portion 31 of the shoelace 3 pulls the medial and lateral edges of the second opening 1B of the main upper 11 toward the center in the foot width direction, causing the main upper 11 to tighten around the wearer's foot in the foot width direction. On the other hand, pulling the second portion 32 of the shoelace 3 pulls the medial and lateral edges of the second opening 1B of the main upper 11 toward the center in the foot width direction, and also pulls the medial tongue 21 and the lateral tongue 22 of the shoe component 12A toward the center in the foot width direction. Because the tips of the medial wing 122 and the lateral wing 123 of the shoe component 12A are sewn to the midsole, when the medial tongue 21 and the lateral tongue 22 are pulled toward the center in the foot width direction, the arch formed by the shoe component 12A lowers, and the shoe component 12A holds the instep of the wearer. Therefore, when second portion 32 of shoelace 3 is pulled, shoe component 12A holds the instep of the wearer, and main upper 11 tightens the wearer's foot in the width direction. Because shoe component 12A is made of a material with different elasticity from main upper 11, the feeling of hold on the wearer's foot differs depending on whether first portion 31 or second portion 32 of shoelace 3 is pulled.

[0023] In the shoe component 12A according to the first embodiment, the number of tongue eyelets 23 in the inner tongue 21 is greater than the number of tongue eyelets 23 in the outer tongue 22. Therefore, when the second portion 32 of the shoelace 3 is pulled, the inner tongue 21 is pulled more strongly toward the center in the width direction of the foot than the outer tongue 22. Therefore, when the second portion 32 of the shoelace 3 is pulled, the shoe 50 using the shoe component 12A according to the first embodiment can hold the inner side of the wearer's foot more firmly than the outer side.

[0024] As described above, the shoe 50 using the shoe component 12A according to the first embodiment fits the wearer's foot differently when the first portion 31 of the shoelace 3 is pulled and when the second portion 32 is pulled. Therefore, a wearer of the shoe 50 using the shoe component 12A according to the first embodiment can wear the shoe with a tightness that suits their preference. Furthermore, the shoe component 12A according to the first embodiment includes the inner wing 122 and the outer wing 123 in addition to the tongue 121, and therefore can hold the instep of the wearer's foot in a hugging manner. In this way, by using the shoe component 12A according to the first embodiment, an upper 1 that fits the wearer's foot well can be formed.

[0025] Although the example shown here is a structure in which two tongue eyelets 23 are provided in the inner leg tongue portion 21 and one in the outer leg tongue portion 22, the number of tongue eyelets 23 is not limited to the illustrated number. For example, a structure in which three tongue eyelets 23 are provided in the inner leg tongue portion 21 and two in the outer leg tongue portion 22 may be used, which differs from the illustrated number.

[0026] (Embodiment 2) 5 is a plan view of a shoe component according to embodiment 2 of the present invention. The shoe component 12B according to embodiment 2 differs from the shoe component 12A according to embodiment 1 in that one tongue eyelet 23 is formed in the inner tongue portion 21 and two tongue eyelets 23 are formed in the outer tongue portion 22.

[0027] In the shoe component 12B according to the second embodiment, the number of tongue eyelets 23 in the outer tongue 22 is greater than the number of tongue eyelets 23 in the inner tongue 21. Therefore, when the second portion 32 of the shoelace 3 is pulled, the outer tongue 22 is pulled more strongly toward the center in the width direction of the foot than the inner tongue 21. Therefore, when the second portion 32 of the shoelace 3 is pulled, the shoe 50 using the shoe component 12B according to the second embodiment can hold the outer side of the wearer's foot more firmly than the inner side.

[0028] (Embodiment 3) 6 is a plan view of a shoe component according to a third embodiment of the present invention. The shoe component 12C according to the third embodiment differs from the shoe component 12A according to the first embodiment in that a tongue eyelet 23 is provided in the outer wing 123 of the outer foot tongue portion 22.

[0029] The shoe component 12C according to the third embodiment has a tongue eyelet 23 provided on the outer wing 123 of the outer foot tongue 22, and the tongue eyelet 23 of the outer foot tongue 22 is located away from the center in the foot width direction. Therefore, when the second portion 32 of the shoelace 3 is pulled in a shoe 50 using the shoe component 12C according to the third embodiment, the outer wing 123 of the outer foot tongue 22 of the shoe component 12C is pulled toward the center in the foot width direction, and the wearer's instep is not pressed against the portion of the tongue 121 that is closer to the outer foot than the center in the foot width direction. Therefore, the shoe 50 using the shoe component 12C according to the third embodiment provides a softer impact on the wearer's instep, improving comfort for the wearer.

[0030] (Fourth embodiment) 7 is a plan view of a shoe component according to a fourth embodiment of the present invention. A shoe component 12D according to the fourth embodiment has a plurality of tongue eyelets 23 provided at the same position in the front-to-rear direction but at different positions in the foot width direction. Specifically, the shoe component 12D according to the fourth embodiment has tongue eyelets 23 provided in the inner tongue portion 21, lined up in the foot width direction, on a portion of the tongue 121 closer to the inner foot than the center in the foot width direction, and on the inner wing 122. Furthermore, the shoe component 12D according to the fourth embodiment has tongue eyelets 23 provided in the outer tongue portion 22, lined up in the foot width direction, on a portion of the tongue 121 closer to the outer foot than the center in the foot width direction, and on the outer wing 123.

[0031] A shoe 50 using the shoe component 12D according to the fourth embodiment allows a wearer to select which of the multiple tongue eyelets 23 arranged in the width direction of the foot through which to thread the shoelace 3. Threading the shoelace 3 through a tongue eyelet 23 closer to the center of the foot width direction among the multiple tongue eyelets 23 arranged in the width direction of the foot provides a stronger hold on the instep of the wearer's foot, while threading the shoelace 3 through a tongue eyelet 23 farther from the center of the foot width direction provides a weaker hold on the instep of the wearer's foot. Therefore, a wearer of a shoe 50 using the shoe component 12D according to the fourth embodiment can customize the hold on the instep of the wearer's foot. Furthermore, by changing the tongue eyelet 23 through which the shoelace 3 is threaded in the front-to-back direction, the hold on the instep of the wearer's foot can be changed in the front-to-back direction. For example, customization is possible, such as weakening the hold on the portion of the instep closer to the toes and strengthening the hold on the portion closer to the ankle.

[0032] (Embodiment 5) 8 is a plan view of a shoe component according to a fifth embodiment of the present invention. The shoe component 12E according to the fifth embodiment is composed of a tongue 121 and an inner wing 122, and differs from the shoe component 12A according to the first embodiment in that it does not include an outer wing 123. A shoe 50 using the shoe component 12E according to the fifth embodiment can improve the hold of the wearer's instep in a portion closer to the medial side of the center in the width direction of the foot. Furthermore, because the shoe component 12E does not include an outer wing 123, the shoe 50 using the shoe component 12E according to the fifth embodiment can achieve a lighter weight.

[0033] Although the shoe component 12E described here has a structure that is composed of the tongue 121 and the inner wing 122 and does not have the outer wing 123, the shoe component 12E may have a structure that is composed of the tongue 121 and the outer wing 123 and does not have the inner wing 122. By configuring the shoe component 12E to have a structure that is composed of the tongue 121 and the outer wing 123, the shoe 50 using the shoe component 12E can improve the hold of the portion of the instep of the wearer that is closer to the outer side of the center in the foot width direction.

[0034] (Sixth embodiment) 9 is a plan view of a shoe component according to a sixth embodiment of the present invention. The shoe component 12F according to the sixth embodiment differs from the shoe component 12A according to the first embodiment in that the tongue eyelet 23 is formed only in the medial tongue 21, and not in the lateral tongue 22. When the second portion 32 of the shoelace 3 is pulled in the shoe 50 using the shoe component 12F according to the sixth embodiment, the medial tongue 21 is pulled toward the center in the width direction of the foot, and the shoe component 12F holds the medial portion of the instep of the wearer's foot.

[0035] In the shoe 50 using the shoe component 12F of embodiment 6, like the shoe 50 using the shoe component 12A of embodiment 1, the outer wing 123 and the inner wing 122 are fixed to the main upper 11 and the midsole, so the position of the shoe component 12F is less likely to shift.

[0036] The configurations shown in the above embodiments are examples of the content of the present invention, and may be combined with other known technologies, and some of the configurations may be omitted or modified within the scope of the gist of the present invention.
