发明名称 Pitching practice target
摘要 Pitching practice targets teach a pitcher to deliver accurate pitches. A tripod assembly is attached to one end of a body. The height of the pitching practice target can be adjusted by telescoping first and second body extensions inserted into the body's opposing end and telescoping lower legs inserted into the upper legs of the tripod assembly. The upper legs are hingedly attached to the body so that they can be folded up when not in use. An arm collar attaches one end of an arm to the second body extension. A target is suspended from the arm by chains hung from chain hooks. A target retainer connects the bottom edge of the target to the body's opposing end. The opposing end of the arm is bent at an angle and forms a triangular structure in conjunction with an arm support.
