  • Patent number: 4266778
    Abstract: A game apparatus for repeatedly catching and relaunching a ball into the air comprises a pair of congruent straps with the ends superposed for grasping in the player's hands. Stacking the straps creates a separation between their intermediate portions so that with the exercise of some skill a ball in flight may be allowed to pass through an opening in the upper strap and caught on a hole in the lower strap. Upon smartly drawing the straps taut, the ball is relaunched. Attached to the upper strap is a frusto-conical shell axially aligned with the holes in the straps which increases the ease with which the ball may be intercepted.
