  • Pitching training tool with indicator
    Patent number: 6651497
    Abstract: The present invention provides a pitching training tool, comprising a rod-shaped body portion, which has a hollow, cylindrical shaft portion that is lighter than a regulation ball, and a gripping portion, which is integrally formed to one end of this shaft portion; an acceleration sensor or other such detector, which is incorporated in the gripping portion side of this rod-shaped body portion, and which detects a state of motion when the rod-shaped body portion is swung around; an arithmetic processing portion for performing computations based on motion state data from this detector; and a display for displaying the results of computations by the arithmetic processing portion, and is constituted so as to compute in the computing portion at least the rotational speed of the rod-shaped body portion based on the detection results by this detector and to display same.
