Abstract
Abstract A general purpose target for defining a window in space is provided by an F shaped frame having spaced parallel vertical ribbons extending between opposing horizontal arms of the F shape to define a strike zone. One of the ribbons may be removed to enable a bat to swing through the strike zone. The frame may be elevated when the window in space should be higher, as for an archery target, for exmaple. A colored sleeve may be disposed on each horizontal arm to define the width of the strike zone. The F shaped frame may be yieldably mounted by a spring on a support stand, or the frame may be rotatably mounted in the stand, to bend or rotate when struck by a thrown ball or swung bat.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
115 words
A baseball pitcher's practice target comprising a frame having at least one vertical and two horizontal frame members joined together to form the frame in an F shape, a pair of spaced parallel vertical boundary marker means extending between the horizontal frame members in said F shape whereby the target is defined by a window of space within the area between the horizontal frame members and the vertical marker means, means for marking a limited distance along the length of said horizontal frame members to fix and define the width between said vertical boundary marker means of said window of space forming said target area and means for supporting said target on a support surface
Claim 2
Dependent Claim
115 words
A baseball pitcher's practice target comprising a frame having at least one vertical and two horizontal frame members joined together to form the frame in an F shape, a pair of spaced parallel vertical boundary marker means extending between the horizontal frame members in said F shape whereby the target is defined by a window of space within the area between the horizontal frame members and the vertical marker means, means for marking a limited distance along the length of said horizontal frame members to fix and define the width between said vertical boundary marker means of said window of space forming said target area and means for supporting said target on a support surface
Claim 3
Dependent Claim
