    摘要: By providing a suction cup dart or shuttlecock in combination with a hand-held paddle or target which incorporates a dart-adhering or holding zone and a dart-rejecting zone, a unique game is provided. Furthermore, the suction cup portion of the dart or shuttlecock is flexibly mounted to the dart body, thereby allowing the shuttlecock or dart to hit the adhering zone of the paddle or target at angles other than merely perpendicular and adhere to the surface.

    摘要: A device for practicing tennis rebounds comprising an anchor or weighted base, a tennis ball and a generally elastic cord connected therebetween. The line or cord is provided with adjusting means for varying the length of the cord from a maximum length to one-half thereof, thereby enabling the ball return speed to be controlled by setting a desired or predetermined length for the elastic cord. The greater the length of the elastic cord, the slower the return of the tennis ball.
