ABSTRACT:
A sports practice device for practicing the stroking motion used in games such as tennis, baseball, squash and the like includes a pair of guide rails mounted to the floor and ceiling of a room, a pair of carriages constrained to move relative to the rails between stops mounted in the rails, and a ball secured to an elastic cord which in turn is secured to the carriage members thereby suspending the ball a pre-determined distance above the floor at a hitting position. When the ball is hit, motion is imparted to the carriage members which move along the guide rails until their motion is stopped by the stops. The ball continues to move stretching the elastic cord which after full stretch snaps the ball back to its initial position.
