Title: Golf putting trainer
Inventor: HONMA MASARU
IPC: A63B69/36
Filed: 1990-08-02
Abstract: PURPOSE:To provide a compact putter trainer capable of freely selecting a distance and gradient from a ball driving position to a cup by providing a film support plate, piezoelectric plastic film, comparator means and judgment result informing means. CONSTITUTION:When a ball 20 collides with a film support plate 5 in a recess 2, a piezoelectric film 6 is deformed together with the film support plate 5, so that a piezoelectric plastic film 6 generates piezoelectricity through a piezoelectric effect. The height of generated voltage corresponds to the intensity of the ball 20 colliding with the film support plate 5. Thus, the output voltage of the piezoelectric plastic film 6 amplified by an amplifier 13 causes the intensity of driven ball to be judged into three kinds by a comparator 14. By properly determining the threshold value of the comparator 14, the output voltage ranges of the three kinds of piezoelectric plastic films 6 to be judged by the comparator 14 are adapted to correspond to 'too weak driven ball', 'proper intensity driven ball' and 'too strong driven ball', respectively.
