发明名称 Fixed hand span device for bowler
摘要 A semi-rigid device utilized on the hand for support in bowling, comprising a generally triangularly shaped member designed for insertion between two fingers of the hand, such as between the index finger and the middle finger, so as to define a consistent spread or span. Securing means are removably attached to the member, with such securing means encircling at least part of the hand or wrist of the user, thus to prevent dislodgement of the generally triangularly shaped member from the selected position between the fingers. I prefer to use a hand-encircling or wrist-encircling strap as the securing means, and I also prefer to use Velcro on the generally triangularly shaped member as well as on the interior portion of the strap in order that proper positioning of the member on the strap may be readily achieved. Additionally, I may utilize two generally triangularly shaped members on occasion, with one of these employed between the index finger and the middle finger, and the other employed between the ring finger and the little finger.
