Abstract
A device for teaching baseball batting techniques in which a base (10) provides a well (12) for one of the batter's feet and an arm (14) provides a yieldable barrier that reminds the batter whenever he has stepped away from the pitcher's mound and into the arm. The arm (14) is pivoted such that it forms a yieldable barrier that does not trip the batter. The device also preferably includes a chord (20) that is adjusted to a length such that it checks the batter's swing at levels above his strike zone.
Claims4
A device for teaching baseball batting techniques, said device comprising:
- a base having a well therein for accomodating one foot of a batter;
- and
- a guide arm flexibly connected to the base such that it is pivoted between one position substantially normal to the base and a second position that is substantially parallel to the base, said guide being sufficiently high when in the one position to provide a yieldable barrier to the other foot of a batter striding into it.
