Golf swing positioning indication method and apparatus

Abstract

The present invention discloses a method and device for indicating the positioning of a golf swing, characterized in that a plane formed by projection of a light source, at a certain angle with the ground, is served as a reference plane to allow a golfer to directly swing on the reference plane or swing in a swing plane parallel to the reference plane during a swing; and a point optionally selected from an intersection position of the swing plane and the ground is served as a spot, so that the swing path and the hitting point are unified in the swing plane to guide a correct swing. The method and device provided by the present invention indicate, by forming a plane wall by light projection, that the swing path, the hitting point and the target direction are unified in this plane to guide a correct swing, and thus have good popularization value.

I claim:

         2 . The method for indicating the positioning of a golf swing according to  claim 1 , characterized in that the reference plane is a light projection wall at a certain angle with the ground; a point optionally selected from a projection of the light projection wall onto the ground is served as a spot, with the axial direction of the projection being the same as the target direction; a club shaft is projected onto the projection wall, so that the swing path, the hitting point and the target direction are unified in the swing plane to guide a correct swing. 
     
     
         3 . The method for indicating the positioning of a golf swing according to  claim 1 , characterized in that indication members are provided, within a projection area of the light source, on the left and right sides beyond a swing area of a golfer, respectively, with the indication members on the two sides being located in the swing plane. 
     
     
         4 . The method for indicating the positioning of a golf swing according to  claim 1 , characterized in that the reference plane is a light projection wall at a certain angle with the ground; and a point optionally selected from a projection of the light projection wall onto the ground is served as a spot, with the swing plane passing through the spot and being parallel to the light projection wall. 
     
     
         5 . The method for indicating the positioning of a golf swing according to  claim 1 , characterized in that an included angle between the reference plane of light projection and the ground is 45° to 65°. 
     
     
         6 . The method for indicating the positioning of a golf swing according to  claim 1 , specifically comprising the following steps:
 a. first, adjusting an included angle between the reference plane of projection of a light source and the ground, and optionally selecting a point from a projection of the light source onto the ground as a spot;   b. positioning the shaft within the coverage of the light projection, and adjusting the angle of inclination of the shaft to be the same as that of the reference plane; and   c. swinging, with the shaft being kept to move within the coverage of the light projection during a swing.   
     
     
         7 . The method for indicating the positioning of a golf swing according to  claim 1 , specifically comprising the following steps:
 a. first, adjusting an included angle between the reference plane of projection of a light source and the ground, and optionally selecting a point from a projection of the light source onto the ground as a spot;   b. positioning the shaft beyond the coverage of the light projection, keeping the shaft parallel to the reference plane, and adjusting the angle of inclination of the shaft to be the same as that of the reference plane; and   c. swinging, with the shaft being kept to move in a plane parallel to the reference plane during a swing.   
     
     
         8 . A device for indicating the positioning of a golf swing according to  claim 1 , comprising a support and a projector provided on the support, with a light beam from the projector being obliquely projected into a hitting area. 
     
     
         9 . The device for indicating the positioning of a golf swing according to  claim 8 , characterized in that the width of the light beam from the projector is within 30 cm, and an included angle between a projection area of the projector and the ground is 45° to 65°. 
     
     
         10 . The device for indicating the positioning of a golf swing according to  claim 8 , characterized in that the projector is an I-shaped projector or a point-like multi-light-source projector; and a lifting device and a moving holder for adjusting to projection angle of the projector are provided between the support and the projector. 
     
     
         11 . The device for indicating the positioning of a golf swing according to  claim 8 , characterized in that a light prompt device is provided on the club shaft, the light prompt device being reflective paper stuck onto the club shaft or reflective coating applied onto the club shaft or giving a prompt by sound and/or flash. 
     
     
         12 . The method for indicating the positioning of a golf swing according to  claim 2 , characterized in that indication members are provided, within a projection area of the light source, on the left and right sides beyond a swing area of a golfer, respectively, with the indication members on the two sides being located in the swing plane.
