Iwao Fukino has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A recess portion is formed on a front side of a head body, and a gel is placed in the recess portion. A face member is fixed on the head body so as to seal the gel in the recess portion. Thus, the gel can be certainly provided on the rearward of the face, whereby a hitting force (striking force) can be improved, while a sound generated when hitting a golf ball can be reduced. The sealed gel sticks to the recess portion without forming any space in a condition that it is pressed therein. Thus, the sound generated when hitting a golf ball can be made uniform, ensuring the transmission of a force for hitting a golf ball.
