Abstract
An extensible exercise golf club including a golf club shaft comprising a plurality of telescopic interlocking shaft lengths which function to extend from a collapsed position to a fully extended position as a result of the force generated by the swinging action of the golf club and automatically return to the collapsed position by the force of vacuum generated within the shaft as the shaft sections are telescopically extended.
Claims6
An extensible exercise golf club comprising:
- a club head member, a club handle member, and a club shaft member disposed therebetween, said club shaft member including:
- a plurality of telescopic tubular members which telescopically fit into each other for slidably extending from a telescopically collapsed position to a telescopically extended position, said telescopic tubular members, when in the extended position, defining an internal space,
- extended raised portions disposed on the outer and inner end portions of adjacent telescopic tubular members for slidably interlocking said adjacent telescopic tubular members together, and
- a cap for covering the end opening of the largest of said plurality of telescopic tubular members;
- and
- a weighted member attached to the end portion of the smallest one of said plurality of telescopic tubular members;
- and said club further including means
- whereby upon swinging the golf club, the club shaft member of the golf club is telescopically extended while simultaneously creating a vacuum within the internal space of the club shaft, and upon finishing the swing, the club shaft member of the golf club is automatically collapsed by the force of the vacuum generated in said internal space of the club shaft.
