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-described problems and achieve the object, the upper according to the present invention comprises a cloth-like base material having at least one layer, and a plurality of linear members formed independently of each other. ing. 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. 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.
