发明名称 TRAINING APPARATUS FOR DEVELOPING PROPER TENNIS SWING TECHNIQUE
摘要 A training apparatus for learning and improving upon proper tennis swing development. The apparatus has a rectangular frame mounted onto adjustable and telescoping vertical support members. The proximal end of the frame is attached to a return guide ramp, which is curved in shape to cause a ball to be returned at a correct height for the user. The distal end of the frame is attached to a backstop panel, which is arranged upwardly oriented at a predetermined angle to return a ball at a predetermined trajectory. A flexible material is disposed across the width of the rectangular frame and extends to the backstop panel and return guide ramp, and is rigid enough to provide a ball support and return surface.

主权项 1. A training apparatus to aid in proper tennis swing technique comprising: a) a frame made up of two parallel frame members; b) a backstop panel connecting said frame members at a distal end thereof, said backstop panel being movable into a predetermined angle to return a ball at a predetermined trajectory; d) a return guide ramp connecting said frame members at a proximal end thereof, and said return guide ramp being adjustable relative to the frame at the connection to the proximal end of said frame member and is curved in shape to cause a ball to be returned to a user at the correct height for a respective user; d) a vertical support at a distal end and a vertical support at a proximal end of said frame members; and e) a flexible material disposed across the width of said parallel frame members, and extending to the backstop panel and return guide ramp, and connected thereto for providing a ball support and return surface.
