Non-sewing material for a footwear upper, footwear upper and footwear using the same

Abstract

A material for a footwear upper, includes a first side corresponding to an inner foot top and an inner side of a foot, a second side corresponding to an outer foot top and an outer side of the foot and extending outwards from an end of the first side to face the first side, a first wing portion extending outwards from the first side in a wing shape, and a second wing portion extending outwards from the second side in the wing shape. The first side and the second side, the first side and the first wing portion, and the second side and the second wing portion are integrated with each other, respectively so that a loss of the material may be reduced and manufacturing efficiency may be improved.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND CLAIM OF PRIORITY[0001]The present application claims the benefit of Korean Patent Application No. 10-2014-0045058, filed Apr. 15, 2014 in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates, in general, to a non-sewing material for a footwear upper, a footwear upper and footwear using the material, and, more particularly, to a non-sewing material for a footwear upper, a footwear upper and footwear using the material, in which a wing is provided on each of an inner side and an outer side, thus reducing a loss of the material and improving manufacturing efficiency.[0004]2. Description of the Related Art[0005]Generally, footwear includes two main members, i.e., an upper and a sole structure. The upper is secured to the sole structure and defines an opening in the footwear to receive the foot comfortably and safe...

AI Technical Summary

Benefits of technology

[0019]As is apparent from the above description, the present invention is advantageous in that the base portion of fabric that has hitherto been disposed of is incorporated into the upper material, thus maximally preventing the loss of material when the footwear is made, and in that the wing portion is provided on the outer portion of the upper in such a way as to extend therefrom, so that the upper itself can serve as the support portion, thus minimizing the formation of the support portion, and in that the bottom portion of the upper is formed on the extending wing portion, thus allowing the bottom portion of the upper to be easily formed, therefore enhancing the process efficiency and minimizing the defective rate of a product.

Problems solved by technology

However, the support portion occupies a large area of the fabric, thus causing a waste of the fabric, and besides, the formation of the support portion leads to an inefficient process.

Particularly, portions of the fabric other than a portion on which the upper is formed are disposed of, thus resulting in the loss of the fabric and consequently the waste of the material.

Such an operation requires highly skilled workers and increases a defective rate.
