发明名称 EXERCISING AND TRAINING TYPE GOLF CLUB
摘要 The pivoted member at the upper end of the golf club shaft, which is biased outwardly by a compression spring, is adapted to be squeezed by the uppermost hand of the user and moved against the fixed semi-cylindrical portion of the shaft to provide a generally cylindrical grip portion. If the gripping force exerted by the golfer's hand is not sufficient to compress the spring and force the pivoted member against the shaft, an awkward and uncomfortable grip portion is provided which prevents the golfer from swinging the club in the proper manner.
