Golf swing training device

Abstract

A golf swing training device comprises a club member and at least one weight member. The weight member includes a mating structure for securing the weight member to a complementary mating structure in the shaft portion of the club member. The weight member can be secured to the shaft in at least three positions including a first position at the top of the shaft adjacent the handle, a second position at or near the midpoint of the shaft and a third position at or near the distal end of the shaft.

What is claimed is:  
     
         1 . A golf swing training device comprising a club member and at least one weiglht member, wherein said club member comprises a handle portion and a shaft portion extending from said handle portion, wherein said shaft portion comprises shaft mating structure for fastening said weight member to at least three positions comprising a first position in the section adjacent to said handle portion on the opposite end from the distal end of said shaft portion, a second position between said first position and the distal end of said shaft portion, and a third position in a section including the distal end of said shaft portion, wherein said weight member has weight mating structure for fastening said weight member to said shaft mating structure, and wherein at least one weight member is secured to at least one position along said shaft portion.  
     
     
         2 . A device according to  claim 1 , wherein said shaft mating structure comprises an outwardly threaded surface.  
     
     
         3 . A device according to  claim 1 , wherein said shaft portion has a unitary structure, wherein said shaft mating structure comprises shaft fastening bore holes, perpendicular to direction of the shaft, adapted to receive pins for fastening weights to said shaft, wherein said weight member has an annular configuration with a coaxial bore axially slidably received by said shaft portion, wherein said weight mating structure comprises weight fastening bore holes, complementary to the shaft fastening bore holes, perpendicular to and bisecting said coaxial bore, adapted to receive pins for fastening weights to said shaft, and wherein said weight is fastened to said shaft by fastening pins.  
     
     
         4 . A device according to  claim 1 , wherein said handle portion is attachable to and detachable from said shaft portion, wherein said shaft portion comprises at least two shaft sections which are attachable to and detachable from one another and attachable to and detachable from said handle portion, wherein said weight member is attachable to and detachable from said shaft sections and said handle portion, wherein, when said device is assembled for golf training, said handle portion and said shaft sections are either connected to one another directly, or with at least one weight member there between, functioning as an adapter connector, provided that, when said handle portion and said shaft sections are connected to one another directly, at least one weight member is attached to the distal end of said shaft portion.  
     
     
         5 . A device according to  claim 4 , wherein said handle portion, said shaft section and said weight member are attachable to and detachable from one another by a male/female screw threading arrangement.  
     
     
         6 . A kit for assembling a golf swing training device according to  claim 1 , said kit comprising a club member and at least one weight member, wherein said club member comprises a handle portion and a shaft portion extending from said handle portion, wherein said shaft portion comprises shaft mating structure for fastening said weight member to at least three positions comprising a first position in the section adjacent to said handle portion on the opposite end from the distal end of said shaft portion, a second position between said first position and the distal end of said shaft portion, and a third position in a section including the distal end of said shaft portion, wherein said weight member has weight mating structure for fastening said weight member to said shaft mating structure.  
     
     
         7 . A kit according to  claim 6  comprising at least three weight members.  
     
     
         8 . A kit according to  claim 7 , wherein said shaft mating structure comprises an outwardly threaded surface.  
     
     
         9 . A kit according to  claim 7  further comprising fastening pins, wherein said shaft portion has a unitary structure, wherein said shaft mating structure comprises shaft fastening bore holes, perpendicular to direction of the shaft, adapted to receive pins for fastening weights to said shaft, wherein said weight member has an annular configuration with a coaxial bore axially slidably received by said shaft portion, wherein said weight mating structure comprises weight fastening bore holes, complementary to the shaft fastening bore holes, perpendicular to and bisecting said coaxial bore, adapted to receive pins for fastening weights to said shaft.  
     
     
         10 . A method for training a golf swing using a golf swing training device according to  claim 1 , said method comprising the steps of: 
 (a) positioning a weight member in said first position;    (b) swinging said training device with the weight as positioned in step (a);    (c) repositioning a weight member to said second position;    (d) swinging said training device with the weight as positioned in step (c);    (e) repositioning a weight member to said third position; and    (f) swinging said training device with the weight as positioned in step (e).
