Abstract
A pitching practice device for indicating and simulating the height and width of a strike zone for a typical batter, the device having a base slightly wider than home plate and two laterally spaced, upwardly extending posts connected to the base, the posts each having a plurality of slidably engaged sleeves that are independently adjustable to indicate the top and bottom of the strike zone, and the posts and sleeves having contrasting colors.
Claims12
A pitching practice device indicating a simulated strike zone height and width, the device comprising:
- a base having a width at least as great as a simulated strike zone width;
- two posts extending vertically upward from the base and supported only by the base, the posts being taller than a simulated strike zone height and being separated by a lateral distance approximating the simulated strike zone width and devoid of structure between the posts or inside the simulated strike zone;
- two sleeves coaxially aligned with and slidably disposed on each post to define a longitudinal section of each post that is visible between the sleeves;
- and
- at least one elastomeric O-ring adjustably positioning each sleeve on the post on which the sleeve is slidably disposed to indicate one of an upper limit and a lower limit of the simulated strike zone distance not height;
- the sleeves on each post contrasting in color with the longitudinal section of the post between the sleeves.

A pitching practice device indicating a simulated strike zone height and width, the device comprising:
- a rectangular base having a width at least as great as a simulated strike zone width;
- two posts extending vertically upward from the base and supported only by the base, the posts being taller than a simulated strike zone height and being separated by a lateral distance approximating the simulated strike zone width and devoid of structure between the posts or inside the simulated strike zone;
- the base and posts constructed of substantially rigid, tubular polymeric material;
- two foamed polymeric sleeves coaxially aligned with and slidably disposed on each post to define a longitudinal section of each post that is visible between the sleeves;
- and
- at least one elastomeric O-ring adjustably positioning each sleeve on the post on which the sleeve is slidably disposed to indicate one of an upper limit and a lower limit of the simulated strike zone height;
- the sleeves on each post contrasting in color with the longitudinal section of the post between the sleeves.
