Golf swing controller

Abstract

A swing controller comprises three parts: an attachment part for attachment to the handle of the golf club, a main part including a main cylinder with spike and supporting three antifriction bearing rings and club face scale, and a telescope part including a telescoping cylinder with groove and O-ring disposed at a lower end of the telescope part and a positioning part for check points for indicating the position of the club and disposed at the upper end of the telescope part. The telescope part is extendable and allows adaptation to short golf clubs, to medium golf clubs and to long golf clubs. An extended axis of the club shank is produced by attaching the swing controller onto the end of the club handle. This renders possible and produces an effective, visual control for all axial planes.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.  
     
         1 . A swing visualizing and controlling device for allowing to correct swinging and holding of a golf club comprising 
 an attachment part for attachment to a handle of a golf club;    a main part including    a main cylinder with a spike for engaging a shank of a golf club,    three antifriction bearing rings disposed on the main cylinder,    a club face scale slidingly disposed on the main cylinder;    a telescope part having a lower end and having an upper end including    a telescoping cylinder having a groove disposed at the lower end of the telescope part,    an O-ring seated in the groove;    a positioning part for check points for indicating the position of the club and disposed at the upper end of the telescope part.    
     
     
         2 . The swing visualizing and controlling device according to  claim 1 , further comprising 
 means for extending furnished at the telescoping part for allowing adaptation of the device to short golf clubs, to medium golf clubs and to long golf clubs.    
     
     
         3 . The swing visualizing and controlling device according to  claim 1 , wherein the main cylinder is attachable to the end of a golf club grip, which main cylinder, in its attached state, forms a rigid axial extension of the golf club.  
     
     
         4 . The swing visualizing and controlling device according to  claim 1 , further comprising 
 a pin for attaching one of the three antifriction bearing rings to the main cylinder.    
     
     
         5 . The swing visualizing and controlling device according to  claim 1 , further comprising 
 a second pin for attaching one of the three antifriction bearing rings to the attachment bush.    
     
     
         6 . The swing visualizing and controlling device according to  claim 1 , further comprising 
 a sliding sleeve disposed surrounding the attachment bush.    
     
     
         7 . The swing visualizing and controlling device according to  claim 6 , further comprising 
 an inner groove ring disposed on an inside face of the sliding sleeve.    
     
     
         8 . The swing visualizing and controlling device according to  claim 1  further comprising 
 an outer ring collar surrounding the attachment bush.  
 
     
     
         9 . The swing visualizing and controlling device according to  claim 1 , wherein the telescoping cylinder slides inside the main cylinder.
