Abstract
Abstract This invention describes a basketball training aid in which a basketball is hung by a flexible cord from an arm which juts out from a supporting wall, the other end of the cord hangs vertically along the wall and carries a cylindrical weight which fits, as a piston, inside of a tubular cylinder and is sealed by means of an O-ring, rubber washer, or wiper to the cylinder. The bottom of the cylinder is closed and there is an opening which is covered by a sliding cover so that an aperture of variable size is available to limit the inflow of air as the weighted piston moves up or down. Check valve means may be installed in addition. The cylinder can be raised or lowered which sets the basketball at any desired height above the floor. In operation the basketball player jumps and grasps the ball in both hands and pulls down. Because of the weight, which can be adjusted to any desired value, and the suction created by the seal, the pull can be adjusted to any desired value which forces the player to maintain a strong pressure on the ball. When the ball is released it returns to its regular position as the weight drops to the bottom of the cylinder.
