Description

UPPER, SHOES AND METHOD FOR MANUFACTURING UPPER

The present invention relates to an upper, shoes comprising this upper, and a method of manufacturing the upper.

Conventionally, many techniques have been developed to bring the upper into close contact with the foot by applying tension to the upper. For example, in Patent Document 1, in an upper having a plurality of eyelet holes formed on the left and right side edges of the throat portion, shoelaces are alternately passed through the left and right eyelet holes, and a knitted mesh serving as the base material of the upper is disclosed. A technique for passing an inlaid strand between is disclosed.

The inlaid strands disclosed in Patent Document 1 are arranged on each side of the throat. Each inlaid strand repeatedly extends from the outer edge of the upper toward the throat portion, passes around one eyelet hole, and then returns to the outer edge of the upper. One of the inlaid strands passes around a plurality of eyelet holes provided on one side edge of the throat. The other inlaid strand passes around a plurality of eyelet holes provided on the other side edge of the throat. In the technique disclosed in Patent Document 1, by pulling the shoelace and applying tension to the inlaid strands, it is easy to apply tension to a wide range of the upper.

Japanese Patent No. 6302478

However, in the upper disclosed in Patent Document 1, when the shoelace is pulled from the heel-side end of the shoelace, tension is less likely to be applied to the portion of the inlay strand located closer to the toe side. The inlaid strands must be tensioned by pulling separately from the top to the bottom.

The present invention has been made in view of the above, and an object of the present invention is to obtain an upper that can be tensioned in one action instead of being pulled sequentially from the toe side.

In order to solve the above-mentioned problems and achieve the object, the upper according to the present invention comprises a cloth-like substrate having at least one layer, and a cloth-like substrate arranged side by side on the substrate and formed independently of each other. and a plurality of linear members. Each of the plurality of linear members has a first portion provided at least at one end along the length direction of the linear member and fixed to the layer, and a portion of the linear member other than the first portion. a second portion provided and not secured to the layer. The second portions of adjacent linear members are hooked on each other. Part or all of the second portion of the at least one linear member is exposed to the outside of the substrate.

The upper according to the present invention has the effect of being able to apply tension to the upper with a single action instead of pulling sequentially from the toe side.

In the present embodiment, the base material 20 has two layers 20a shown in FIG. 7 and the like, but the base material 20 may have one layer 20a. When the layer 20a of the base material 20 is a single layer, the second portion 21b of the linear member 21 is formed on the surface of the layer 20a facing the outside of the upper 2 and the surface facing the inside of the upper 2. placed on one side. Part or all of the second portion 21b of the at least one linear member 21 is formed on the surface of the layer 20a, that is, the surface of the layer 20a facing the outside of the upper 2 and the surface facing the inside of the upper 2. It should be exposed on one side. When the layer 20a of the base material 20 is made into one layer in this manner, the weight of the shoe 1 can be reduced.

At least part of the layer 20a shown in FIG. 7 and the like preferably has transparency. When the linear member 21 is hidden by the layer 20a, the linear member 21 can be visually recognized from the outside of the upper 2 by arranging the transparent layer 20a. Thereby, the design of the shoe 1 can be enhanced by exposing the linear member 21 . Also, the tightness of the upper 2 can be visually confirmed.

The stretching direction, number, material, etc. of the linear members 21 shown in FIG. For example, if the shoes 1 are casual shoes, the number of linear members 21 may be reduced. Further, for example, when the shoes 1 are performance shoes such as running shoes, a material with low elasticity may be used as the material of the linear members 21 .

Also, the arrangement of the linear members 21 is not limited to the illustrated example, and may be changed as appropriate according to the use of the shoe 1. For example, if the shoes 1 are casual shoes, the linear members 21 do not need to be arranged on the upper sole portion R4. Further, for example, if the shoe 1 is a core performance shoe for basketball, volleyball, or the like, it is necessary to attach a counter to the heel portion of the shoe 1 to provide stability to the heel portion. It is not necessary to arrange the heel part of the

Although the plurality of linear members 21 shown in FIG. 1 extend in the front-rear direction and are arranged side by side in the foot width direction, they may be arranged side by side in the front-rear direction while extending in the foot width direction. In the case of such a structure, the foot width direction is the first direction, and the front-rear direction is the second direction crossing the first direction. Each linear member 21 extends in a zigzag shape alternately protruding forward and backward in the longitudinal direction from one side to the other side in the width direction of the foot. The second portion 21b of each linear member 21 includes a first hook portion 21c to be hooked by another linear member 21 arranged forward along the front-rear direction, and another portion arranged rearward along the front-rear direction. The second hooking portions 21d hooked on the linear member 21 are alternately formed in the foot width direction. When the wearer of the shoe 1 moves, the skin of the midfoot portion of the foot is distorted such as shrinkage and twisting, and the upper metatarsal portion R2 undergoes shear deformation in the foot width direction. Therefore, when the linear member 21 is arranged to extend in the foot width direction, the elasticity of the linear member 21 arranged in the upper metatarsal region R2 is adjusted to the elasticity of the linear member 21 arranged in the upper forefoot region R1. And, it is preferable to make the stretchability higher than that of the linear member 21 arranged in the upper rear foot portion R3. In this way, the linear members 21 arranged in the upper metatarsal region R2 follow the deformation of the skin of the foot and are easily sheared in the foot width direction. The occurrence of wrinkles in 2 can be suppressed.

Each of the plurality of linear members 21 shown in FIG. 1 may have at least one of the same stretchability and tensile strength, or may have a portion of the plurality of linear members 21 and a plurality of linear members. At least one of elasticity and tensile strength may be different from the rest of the material 21 . For example, in the example shown in FIG. 1, since the strongest tension is applied to the two linear materials 21 that are directly pulled, the tensile strength of these two linear materials 21 is greater than the tensile strength of the other linear materials 21. In order to increase the strength and to easily transmit the tension to the other wire members 21, the elasticity of the other wire members 21 should be higher than the elasticity of the two wire members 21 to facilitate stretching. By changing the material of the linear materials 21, the number of fibers constituting the linear materials 21, and the like, the elastic properties and tensile strengths of the linear materials 21 can be varied.

At the position where the linear material 21 shown in FIG. 1 is exposed, that is, at the position where the linear material 21 is pulled, the part where the tension is easily applied and the part where the tension is not easily applied in the upper 2 changes, so the position where the linear material 21 is pulled is It may be changed as appropriate according to the use of the shoe 1 .

In this modification, part of the second portions 21b of the four linear members 21 are exposed to the outside of the base material 20 through the holes 20g. In this modification, when the second portions 21b of the four linear members 21 exposed to the outside of the base material 20 are pulled rearward, tension is applied to the pulled linear members 21 and the other linear members are pulled. Tension is also applied to the material 21 interlockingly, and tension is also applied to the base material 20 to which each linear material 21 is fixed. Therefore, in this modified example, tension can be applied to the upper 2 with a single action. In particular, by pulling the linear member 21 from the heel side, it is possible to simultaneously apply tension to the upper 2 in the longitudinal direction and the foot width direction. In addition, in this modified example, by pulling the linear member 21 from the heel side, tension is easily applied to the heel portion of the shoe 1, so that the wearer's feeling of holding the heel portion can be enhanced. In addition, in this modification, the second portion 21b positioned between the first layer 20b and the second layer 20c is exposed to the outside of the base material 20 through the hole 20g, and the exposed portion is placed outside the shoe 1. Since the linear material 21 can be pulled from the wearer's foot, it is possible to prevent the linear material 21 from hitting the wearer's foot.

As shown in FIG. In this modification, the second portion 21b located between the first layer 20b and the second layer 20c is exposed to the outside of the base material 20 through the opening 20h, and the exposed portion can be pulled from the outside of the shoe 1. Therefore, it is possible to prevent the linear member 21 from hitting the wearer's foot. When the second portion 21b is exposed to the outside of the base material 20 through the opening 20h formed in the outer edge of the base material 20, it is provided at one end of the linear material 21 along the length direction. The second portion 21b may be exposed to the outside of the base material 20 through the opening 20h.
