  • Patent number: 4936577
    Abstract: A basketball training and retrieving arrangement defined by an enlarged arch or ring mounted on a framework supported on a common basketball backboard and extending above and around an existing basketball goal. The invention plays importance in perfecting a player's ability, as from shooting at a three point line. Whether or not the basketball passes through the hoop of the goal, the basketball is introduced into a return which is selectively movable to the player's shooting location. The basketball return is rotatably mounted at a location below the basketball goal and includes a structural configuration which "kicks" the basketball into return movement along downwardly inclined rails.
