Title:
GOLF CLUB FOR PRACTICE
Document Type and Number:
WIPO Patent Application WO/2006/061889
Kind Code:
A1
Abstract:
A golf club for practice enabling a swing in a correct form without being aware of it, capable of actually hitting a ball in the form, and also enabling the easy and clear recognition of the defect of swing and the easy correction of the defect. A head support axis (B-B) of a club head (20) is displaced to the toe side of the club head (20) relative to the grip axis (A-A) thereof. Since a head balance is lost by the intentional displacement, a reasonable correct form can be completed by normally swinging the golf club. The displaced amount (D) of the head support axis (B-B) relative to the grip axis (A-A) is set to half to twice a length (S) between the heel and the toe of the club head (20).
