Abstract

A baseball target device is disclosed wherein the device includes a target that is adjustable in height and length to simulate the strike zones of different size batters. In the preferred embodiment, the device utilizes a base to which a telescopically adjustable vertical frame is attached, wherein the frame supports an adjustable spring-loaded window shade device. The shade of this device hangs down from the frame and its unrolled portion defines a "strike zone" for the pitcher. A picture of a crouched catcher and umpire is imprinted on the shade to give the target a realistic effect. The pitcher may adjust the target to the size of the strike zone for a particular batter by adjusting the telescopic frame to the height of the batter'"'"'s shoulder and then adjusting the target shade to the batter'"'"'s knee, thus creating a target whose size and location simulates the exact strike zone for that particular batter.

Claims

1. A baseball target device comprising:

a. a base;

b. a tubular frame extending substantially vertically therefrom;

c. said frame having a spring-loaded roller mechanism mounted across it in a substantially horizontal position, whereby the top of the roller defines the top level of a simulated strike zone for the device;

d. said frame having a pair of telescopic vertical legs whose overall length can be adjusted to raise or lower the height of the roller to conform to the actual top level of a particular batter'"'"'s strike zone; and

,

e. a target sheet attached to the roller for simulating the strike zone, said sheet having a width equal to that of any batter'"'"'s strike zone, said sheet also having one end fixedly attached to the roller so that a midsection of the sheet is rollable upon the roller and a second, free end of the sheet is adapted to hang from it, whereby the unrolled portion of the sheet between the top of the roller and the sheet'"'"'s free end defines the length of the simulated strike zone, the free end defines the lower level of the device'"'"'s strike zone and the length of the simulated zone can be selectively varied by rolling or unrolling the sheet from the roller to simultaneously adjust both the length of the device'"'"'s strike zone and its lower level to conform to the actual length and lower level of the batter'"'"'s strike zone.

2. The device of claim 1 wherein the target sheet has a picture imprinted on it of a crouched catcher and umpire.

3. The device of claim 1 wherein the target sheet has securing means near its free end for removably attaching the sheet to the frame to prevent the sheet from accidentally rerolling upon the spring-loaded roller when the sheet is hit by a pitched ball.

4. The device of claim 1 wherein the target is rectangular and has a substantially constant width equal to that of a standard home plate used in baseball.

5. A baseball target with an adjustable strike zone, said device comprising:

a. a base;

b. a tubular frame extending substantially vertically from the base, said frame having a spring-loaded roller mechanism attached to it that defines the upper limit of a simulated strike zone for the device, wherein said frame also has telescopic means for vertically adjusting the height of the roller mechanism to the shoulder level of a particular batter;

c. a target sheet attached to the roller for simulating the strike zone, said sheet having one end fixedly attached to the roller so that a midsection of the sheet is rollable upon the roller and a second, free end of the sheet is adapted to hang from it, whereby the unrolled portion of the sheet between the top of the roller and the sheet'"'"'s free end defines the length of the lower level of the device'"'"'s strike zone and the length of the simulated zone can be selectively varied by rolling or unrolling the sheet from the roller to simultaneously adjust both the length of the device'"'"'s strike zone and its lower level to conform to the actual length and lower level of the batter'"'"'s strike zone.

6. The adjustable device of claim 5 wherein the target sheet is rectangular and has a constant width corresponding to that of a baseball batter'"'"'s strike zone.

7. The adjustable device of claim 5 wherein the target sheet has the picture of a crouched catcher and umpire on it and the amount of the picture shown to a batter varies with the amount of the sheet that is unrolled from the roller mechanism.

8. The adjustable device of claim 7 wherein the target sheet has securing means near its free end for removably attaching the sheet to the frame to prevent the sheet from accidentally rerolling upon the spring-loaded roller when the target sheet is hit by a pitched ball.

9. A pitcher'"'"'s practice device comprising:

a. a base having two parallel tubular members connected at their midpoints by a modified T-connector to a cross member that is perpendicular to both so that the distance between the outside edges of the two parallel members substantially corresponds to the width of a baseball batter'"'"'s strike zone;

b. an adjustable vertical frame rigidly attached to the modified T-connectors of the base, said vertical frame comprising a pair of parallel, tubular telescoping members attached at their lower end to the base, wherein each of said members has a lower vertical tube attached to the base, said tube having a series of holes that are evenly spaced along its length and an outside diameter slightly less than the inside diameter of a coaxial, upper vertical tube so that the upper tube slides over the lower one, wherein said upper tubes each contain a hole through which a bolt can be placed in order to lock the upper tubes at a specific height on the lower tubes;

c. a pair of bolts that are insertable through the holes in the telescoping members to lock the members at a specific height;

d. a horizontal, tubular cross member connected to the upper end of each telescoping member by elbow connectors so that the outside edges of the telescoping members are substantially the same distance apart as the width of a baseball batter'"'"'s strike zone;

e. a spring-loaded roller mechanism mounted in a horizontal position on the frame flush with the top of it; and

,

f. a target sheet attached to the roller for simulating the strike zone, said sheet having a width equal to that of any batter'"'"'s strike zone, said sheet also having one end fixedly attached to the roller so that a midsection of the sheet is rollable upon the roller and a second, free end of the sheet is adapted to hang from it, whereby the unrolled portion of the sheet between the top of the roller and the sheet'"'"'s free end defines the length of the simulated strike zone, the free end defines the lower level of the device'"'"'s strike zone and the length of the simulated zone can be selectively varied by rolling or unrolling the sheet from the roller to simultaneously adjust both the length of the device'"'"'s strike zone and its lower level to conform to the actual length and lower level of the batter'"'"'s strike zone.
