Title:
AUXILIARY SHOE HEEL AND METHOD OF FABRICATING SAME
Document Type and Number:
WIPO Patent Application WO/2012/081912
Kind Code:
A3
Abstract:
The present invention relates to an auxiliary shoe heel and a method of fabricating the auxiliary shoe heel that includes: a hard heel disposed in the central portion thereof; and a soft heel disposed around the periphery of the hard heel and integrally formed with the hard heel through an insert injection molding process, thereby preventing the soft heel and the hard heel from being separated from each other, and providing cushioning and anti-slip functions. More particularly, a shoe heel comprises a coupling member that includes a coupling end integrally formed with an end of a coupling rod. A hard heel part surrounds the coupling end of the coupling member, and is formed of hard rubber in a semicircular plate shape through an insert injection molding process. A hard heel part includes a plurality of soft heel holes that vertically pass through the hard heel surrounding the coupling end. A soft heel is coupled to the hard heel of the hard heel part through an insert injection molding process. The shoe heel is attached to a main shoe heel that is coupled to the bottom surface of a placement part on which a foot is inserted and placed, and that supports the ground, or is coupled to the main shoe heel through the coupling member so as to function as an auxiliary heel. The soft heel is integrally formed with the hard heel through the insert injection molding process, so as to fill the soft heel holes and surround side and bottom surfaces of the hard heel. Accordingly, the bottom surface of the soft heel covering the bottom surface of the hard heel contacts the ground so as to perform cushion and anti-slip functions. Holes are formed in the hard heel, and are filled with a liquid material through the insert injection molding process to form the soft heel, whereby the periphery of the hard heel and the ground contacting portion thereof are covered with the soft heel, so as to provide the cushion and anti-slip functions.
