Title: GLUING-FREE SHOE AND METHOD FOR MANUFACTURING SAME
Abstract:
The present invention relates to a gluing-free shoe and a method for manufacturing the same, and the purpose of the present invention is to provide a gluing-free shoe and a method for manufacturing the same, wherein coupling between an upper leather and an outsole and a frame, which constitutes a sole, can be made firmly without using glue such that a shoe having excellent air permeability and water discharge functions is provided while improving working environments and productivity and reducing the defective ratio and labor costs. Particularly, the present invention provides a gluing-free shoe comprising an upper leather and a sole coupled to each other without using glue, wherein the upper leather has an upper leather fixing piece formed on the lower end thereof so as to protrude in a corrugated shape, a fixing hole extending through the upper leather fixing piece, a reinforcing core material having high strength and durability is embedded on the lower end of the upper leather and inside the fixing piece; the sole comprises a frame, which is fixed to the upper leather, and an outsole fitted to the frame, the frame is injection-molded using a hard synthetic resin or molded using a rubber molding material, a frame fixing piece is formed on the upper side of the periphery of the frame to be positioned outside the upper leather fixing piece formed on the upper leather, a pin coupling hole being formed in the frame fixing piece, the outsole comprises an upper plate made of a hard synthetic resin and seated on the upper portion of the frame and a lug integrally foam-molded on the upper plate to be fitted to an outsole assembly hole extending through the frame vertically, or the outsole comprises an upper plate and a lug constituting an integrally shaped sole using one of synthetic resin, EVA sponge, PU, and rubber; coupling between the upper leather and the sole is made by a fixing pin fitted into an upper leather fixing hole through the pin coupling hole formed on the frame fixing piece; a head larger than the pin coupling hole is formed on the rear end of the fixing pin, and a hook is formed on the front end thereof to engage with an engaging recess formed on the upper plate of the outsole. In addition, the toe and heel portions of the frame are fixed by sewing according to functionality of the shoe, thereby completing more perfect coupling between the upper leather and the outsole.
