  • Patent number: 3930646
    Abstract: An amusement device simulates the game of tennis and has a miniature playing surface provided with the lines and net that characterize a tennis court. Hitting elements representing opposing players are disposed on opposite sides of the net, and a wire extends over the net and has its ends anchored near the respective elements. The wire simulates the path of a ball, and a bead is threaded on the wire to represent the ball. The two hitting elements are mounted for oscillation about upright axes, and a cam-operated spring drive alternately actuates the elements in a manner to strike the bead and propel it back and forth over the net to simulate the action in tennis.
