GOLF BALL PRACTICE DEVICE |
摘要 |
A golf practice device simulates the appearance and general flight characteristics of an actual regulation golf ball, but commonly only travels about 30-80 feet when impacted by a swung golf club. The device includes a substantially regulation ball connected by a shaft extending diametrically with respect to the ball to a substantially disc-shaped drag element, the disc perpendicular to the shaft and preferably of a one-piece molding of rubber or resilient plastic. The disc has a substantially flat bottom, and the disc and shaft act like a tee, allowing the ball to be "teed up" off any surface. The shaft may be ultrasonically welded to the exteriorly dimpled plastic shell of a regulation golf ball, the shaft extending through a diametrically extending opening in the ball; or the ball, shaft and disc may be unitarily molded of the same plastic material.
