Golf club weighting system with under-grip retention

In a novel approach to golf club counter-weighting, directed to incorporation in a golf club at original manufacture as well as in the after-market, required secure longitudinal retention of the weighting device is accomplished by structure differing from known practice in that the required longitudinal retention is referenced to the top end surface of the golf club shaft by an annular flange configured at the top end of the weighting device and held securely between the cap portion of an original unmodified golf club grip and the top end of the shaft, thus accomplishing the required longitudinal retention of the weighting device with no need for grip modification or friction-gripping the interior surface of the shaft. The flange diameter is sized to fit closely inside the grip so as to also provide lateral retention at the top end of the thusly cantilevered weighting device..

Grip for golf club

In the present invention, there are effects that the grip for golf club can be stably gripped by the thumb and the index finger without applying a large force since the diameter of the lower part of the grip for golf club is thick enough, as well as that the entire weight of the grip is considerably reduced so as to be at the level comparable to the usual grip due to a cut section which is formed by removing, among the lower part of the grip for golf club, the remaining portion except the portion where the thumb and the index finger of the hand which is positioned at the relatively lower position touch, and also that the upper end of a shaft can be easily inserted and the assembly is easy so that there is no worry of degradation of the productivity since the entire thickness of the lower narrow section can be small.. .
