Benefits of technology
The patent text describes a method for hardening a knitted fabric used in a sports shoe by using a thermally fusible yarn. This yarn is applied to the outer surface of the shoe and is fused together by heat treatment, making the fabric harder on the outside and improving the shoe's holdability and comfort. The hardened fabric also has improved solidity and reinforces the shoe's surface. This method is useful for improving the assembly of sports shoes and enhancing the overall quality of the shoe's upper.
Problems solved by technology
As a result of this, when wearing a shoe the hardened first knitted fabric contacts a wearer's foot and thereby wearer's touch on the foot might be deteriorated.
As a result of this, when wearing a shoe the fusion area contacts a wearer's foot and thereby wearer's touch on the foot is deteriorated.

Embodiment Construction
[0040]Referring now to the drawings, FIGS. 1 to 4 show an upper structure for a sports shoe according to an embodiment of the present invention. These drawings illustrate an upper alone. In an exemplification, the upper structure is applied to a walking shoe or a running shoe. Of course, it also has an application to shoes of different kinds.
[0041]As shown in FIGS. 1 to 4, an upper 1 that covers a foot of a shoe wearer is formed of a knitted fabric, which is knitted into a sock-shape. The upper 1 has an opening 1a for entry of the foot into the upper 1. The knitted fabric of the upper 1 comprises a knitted fabric region 1A to 1D (see vertical lines) having thermally fusible yarn that is fusion-bonded, cured and impregnated into the region 1A to 1D, and a knitted fabric region 1E (see white void areas defined by outlines) having no thermally fusible yarn. The thermally fusible yarn is yarn of relatively lower melting point (e.g. low-melting-point nylon) and it includes “ELDER®” of TO...

Abstract
An upper structure for a sports shoe is provided that can not only enhance holdability as an upper but also improve wearer's touch on a foot. In the upper structure for the sports shoe, the upper is formed of a knitted fabric having thermally fusible yarn and another knitted fabric having no thermally fusible yarn. In the knitted fabric having the thermally fusible yarn, the thermally fusible yarn is disposed on an outer surface side of the upper, and on an inner surface side of the upper, a front yarn and a back yarn are arranged in a parallel relationship. The thermally fusible yarn is fusion-bonded and cured in the knitted fabric by heat treatment and the outer surface side of the upper 1 is thus hardened than the inner surface side of the upper.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates generally to an upper structure for a sports shoe, and more particularly, to improvement in structure that can not only enhance holdability or holding property as an upper but also improve wearer's touch on a foot.[0002]An upper structure for a sports shoe was shown in publications such as Japanese patent application publication Nos. 2004-105323 (hereinafter referred to JP'323) and 2006-511306 (hereinafter referred to JP '306).[0003]JP '323 describes that a first region of an upper is formed of a first knitted fabric in which a first synthetic resin fiber having a low softening point is knitted, a second region of an upper is formed of a second knitted fabric in which a second synthetic resin fiber having a higher softening point than the softening point of the first synthetic resin is knitted, and the first knitted fabric is hardened by heating the upper at a temperature that is higher than the softening point of the fi...
