Abstract
An analyzer and practice aid primarily for determining a ball pitcher's or hitter's stride angle and stride length. The analyzer is comprised of a ground or floor mat with a grid imprinted on it, the grid havings a reference point from which reference lines extend forwardly and outwardly at predetermined angles toward a target, such as the home plate. The grid also includes lines that intersect the reference lines for easy measurement of the distance from the reference point toward the target. The mat may also include means behind the reference point for mounting an adjustable pitching rubber. The analyzer can also be used for batting practice and in training for improvement in other sports such as golf for determining a proper stance.
Claims7
An analyzer for measuring the stride length and stride angle of a person pitching a ball toward a target, said analyzer comprising:
- a mat having an upper surface and a lower surface adapted to be supported with the lower surface on the ground or floor;
- a reference point imprinted on the upper surface of the mat;
- a pitcher's rubber positioned on the upper surface of the mat behind the reference point;
- a zero line imprinted on the upper surface of the mat and extending from the reference point toward the target;
- a plurality of angular reference lines each extending outwardly from the reference point generally toward the target and at an angle from the zero line;
- and a plurality of cross reference lines intersecting the angular reference lines at spaced intervals outwardly from the reference point.
An analyzer for measuring the stride length and stride angle of a person throwing or hitting a ball toward a target, said analyzer comprising:
- a mat having an upper surface and a lower surface adapted to be supported with the lower surface on the ground or floor;
- a reference point imprinted on the upper surface of the mat;
- a zero line imprinted on the upper surface of the mat and extending from the reference point toward the target;
- a plurality of angular reference lines each extending outwardly from the reference point generally toward the target and at an angle from the zero line;
- and a plurality of cross reference lines intersecting the angular reference lines at spaced intervals outwardly from the reference point;
- the angular reference lines being spaced apart at equal predetermined intervals, and the cross reference lines being equally spaced concentric lines that extend across and between the angular reference lines at predetermined intervals.
