| 04/07/2005 | US20050075199 Portable playing field for playing a plastic ball and bat game that can be adjusted to accommodate the playing field size, indoor/outdoor use, skill levels, age groups, including professional use. The field automatically determines the hit (ie double or homerun) and the pitch (ie strike). The field is easily portable and stored in a bag, that doubles as the strike zone. A miniature version is used as a game that includes a hitting plate and figurine bat/batter. A manual button releases the pitch and another button swings the bat to hit the pitch. The scoreboard dial keeps track of runs. |
