Abstract:
A golf-swing training device comprising:(a) an elongated shaft for removably mounting a weight member thereonto, the shaft including a first end and a second end;(b) a stopper having a radius greater than the radius of the second end and projecting outwardly therefrom and coaxial therewith, the stopper preventing slidable detachment of a weight member from the shaft;(c) at least one weight member removably mountable to the shaft, the at least one weight member comprising:a body member having a substantially centered aperture, the aperture adapted for securing the member to a golf club shaft, the body member further comprising(i) first and second opposedly-arranged, identical body portions adapted to be freely slidable in a direction parallel to the longitudinal axis of the aperture, each of the first and second body portions having a male pedestal portion, a male foot portion, a U-shaped recess, and an inner surface, wherein each inner surface defines a first female portion for axially slidably receiving the male foot portion of each opposite body portion in an interdigitating relationship and each U-shaped recess of each body portion defines a second female portion for axially slidably receiving the male pedestal portion of each opposite body portion in an interdigitating relationship, the body portions being prevented from radial disengagement by the interdigitation of the two body portions; and(ii) a channel extending radially through the outer periphery of the body member and into the aperture, the channel extending through the inner surface of each body portion and through the interdigitated foot portion of the other body portion thereby defining a notch in the foot portion of the other body member; anda locking member for engaging in the channel when the body portions are assembled onto a golf club shaft, the locking member lockingly engaging the shaft to thereby prevent axial sliding movement of the weighted member relative to the shaft.
