Patent ID: 11083948

Abstract:
A tennis-stroke trainer device is an apparatus that allows a user to perform various tennis strokes repetitively. The apparatus includes a frame, a training ball, a pair of length-adjustable fasteners, and an elastic cord. The frame offset and rotates the training ball around a post. The post is preferably a tennis post. The frame includes a U-shaped bracket, a cantilever arm, a counterfort arm, and a hook. The U-shaped bracket offsets and mounts both the cantilever arm and the counterfort arm with the post. The hook stretches the elastic cord along the cantilever arm. The training ball is preferably a large foam ball and serves as a target for the user. The pair of length-adjustable fasteners mounts the U-shaped bracket with the desired post. The elastic cord retracts the cantilever arm and the counterfort arm, and consequently the training ball after the training ball has been hit by the user.
