ABSTRACT:
A tennis practice device for indoor use has a swingable upright arm pivotally connected to a weighted base. A tennis ball is connected to the top of the arm, and movement of the arm is limited and dampened by two cushions. An elastic strap normally holds the arm against one of the cushions. In the arm, an elongated wire with a spring trunk is surrounded by lengths of tubing arranged in telescopic fashion. The arm is resilient and capable of whip-like movement, rendering the impact resistance presented by the ball against a racquet similar to the resistance of a ball in actual play. Simultaneously, the combination of the pivot means with the resilient nature of the arm permits the ball to escape the follow-through stroke of the racquet, yet quickly return to its normal position to allow the tennis player to repeat strokes in rapid succession.
