International ClassA63B 059/06AbstractA shock absorbing bat comprises a long cylindrical central handle and a main body, both being connected together and held firmly by means of a retaining collar and an elastic ring. An elastic connector is provided which is axially attached to an end piece. This construction can drastically reduce the shock to the batter's arm and the possibility of injury to the elbow is minimized. The construction also increases the impulse, when a ball is struck. | |
