<P>PROBLEM TO BE SOLVED: To provide a mechanical tee for batting practice. <P>SOLUTION: The mechanical tee may present a ball to a batter at various heights, positions, speeds, and angles to simulate real game conditions. The mechanical tee may include a vertical stand 102 with a variable position, retractable post 104 that supports flexible tubing 106 with a suction cup 108 at the end to hold a ball in a suspended manner for striking. The mechanical tee may have a motor and vacuum pump configuration to provide suction, and may automatically feed balls to a batter. The vertical stand 102 may additionally have an air compressor and an attachment for pneumatically tossing or propelling a ball upward for striking. The mechanical tee may move, or toss, a ball to variable and/or random placements within a three dimensional strike zone 110. A portable stand may have several telescopic pistons for lifting a ball at various placements. <P>COPYRIGHT: (C)2013,JPO&INPIT |
