发明名称 Energy dissipating ball tee
摘要 A ball tee is described for supporting a ball as a stationary target at a prescribed elevation to be struck as a practice exercise for a selected sport. The tee structure is formed with a self-supporting material that is capable of absorbing and dissipating energy delivered by violent impact. It is formed of two interfitting members, a base and a shaft. The shaft has a ball receiving support at an outer end that will hold a ball at a prescribed elevation. The shaft is removable from the base which includes a recess formed in its bottom side. This recess may be utilized to support larger balls adjacent to a ground surface primarily for kicking purposes. In another embodiment, the ball support may be provided with gripping members that releasably support a ball at any selected angle. The shaft is formed of a synthetic closed cell material. The nature of the material is such that it will not significantly disrupt the swing path of a bat or the resultant trajectory of the target ball. Further, recoil shock suffered by the person holding the bat or racket is hardly noticeable. The material dissipates the energy of impact and will recover its original geometry quickly after impact.
