Batter's Box
US Patent:
2009023, Sep 17, 2009
Filed:
Feb 20, 2009
Appl. No.:
12/389548
Inventors:
David Lerch - South Riding VA, US
International Classification:
A63B 69/00
US Classification:
473452
Abstract:
The Batter's Box device is an instruction tool to help children, primarily but not limited to ages 5-12, learn two aspects of proper hitting mechanics for baseball and softball: 1) feet placement base, and 2) stride. Stride has two components, length and direction. The batter's box teaches feet placement and stride by limiting the movement of the batter's feet. The batter's box is a rectangular frame that is placed on the ground. The batter stands in the frame of the batter's box and two bungee cords, one attached to the frame in front of the back foot and one attached to the frame in front of the lead, or stride, foot, create a barrier that will constrain the batter's feet (the back foot and the stride foot) if they move with improper technique. The batter's box is adjustable for player's of different height and size. The frame may be widened and the restrictive bungee cords can be placed at various increments to complement longer or shorter legs.
