International Classification:
A63B 69/36
US Classification:
473221
Abstract:
A golf swing modeling device includes a base having a first row of sensors, a striking row of sensors, a second row of sensors and a third row of sensors. The various sensors output individual signals. The striking row of sensors comprises a striking row inside sensor and a striking row outside sensor. A ball striking assembly has a lower ball mounted on a lower ball arm which is mounted on a lower retainer and an upper ball mounted on an upper ball arm which is mounted on an upper retainer. The upper ball has a sensor which outputs a signal when struck. A striking face of the lower ball is placed between the striking row inside sensor and striking row outside sensor. A processor receives individual signals from the sensors. The processor calculates club speed, and club head orientation from individual signals, and the processor provides output.
