The versatile training device for correcting the hitting technique contains the hitting set with the probe of the optimal hit directions designed as the movable disk with the center fastened inside on the support with the aid of the ball joint. Along the external perimeter, the disk is connected with the case through the adjusting springs with the mechanisms of controlling the deviations of the hitting pulses relative to the site of the hit. The corresponding signals are transmitted to the display. At the top, the adjusting mechanism is located. The case of the device is attached to the support with the adjustable height. The mechanism of controlling the deviations of the hitting pulses relative to the site of the hit contains the control probes, the sound amplifier and the electronic unit, all the elements connected in succession. The device is equipped with the additional mechanism of measuring the force of the hit comprising two separately located springs designed in a way allowing for the measurement of the specified force. The springs are fastened rigidly with the forward part of the guide bushings. The rear part is connected with the major bar containing the adjustable loading devices. The bar is attached to the central part of the case being capable of moving along the guide bushings connected with two supports with the bushings for the movement of the auxiliary bars. Opposite to the middle part of the major bar, the pointer and electronic probes are located for the control of the position of the bar. Their signals are transmitted to the sound amplifier and the display. |
