发明名称 Golf swing training machine
摘要 There is described a golf practice device having a golf club guiding member consisting of a single tube wound in the form of a helix having in excess of one and a half turns. The diameter of the helix is somewhat less than the arc of a club head during the golf swing and the guide is supported on the ground or other surface such that the helix lies approximately in the plane defined by the shaft of a golf club during the normal golf swing. One end of the helix terminates adjacent the impact region of the club with the golf ball. The helical guide member extends away from the point of impact in the direction of the back swing. The pitch of the helix increases so that the overlapping turns of the helix are divergent in going from the point of impact to the top of the back swing region of the golf swing. The overlapping turns of the helix are held in fixed spaced relation by a supporting leg in the form of an open loop, the ends of the loop supporting the adjacent overlapping portions of the helical guide. The one end of the helix may be braced from the supporting leg.
