Swing training device

Abstract

A swing training device is disclosed, which comprises a shaft part 14 having a grip part 11 formed as grip on the surface, and a pendulum part 12 extending from the forward end of the shaft part 14 and having flexibility and restoring elasticity for restoration to a substantially straight state. The grip part 11 and the shaft part 14 can be formed as separate parts, and the shaft part 14 may be disposed in the sole inside of the grip part 11.

What is claimed is:  
     
         1 . A swing training device for reforming the swing comprising: 
 a rigid shaft part having a grip part formed as grip on the surface; and    a pendulum part extending from the forward end of the shaft and having flexibility and restoring elasticity for restoration to a substantially straight state.    
     
     
         2 . The swing training device according to  claim 1 , wherein the grip part and the shaft part are formed as separate parts, the shaft being disposed on the sole inside of the grip part.  
     
     
         3 . A swing training device for reforming the swing, comprising: 
 a grip part serving as grip;    a shaft formed at least in the inside of the grip part; and    a pendulum part formed such as to extend from the forward end of the shaft and having flexibility and restoring elasticity for restoration to a substantially straight state.    
     
     
         4 . The swing training device according to  claim 1  or  3 , wherein the pendulum part has such flexibility that it can be flexed along the body when swinging the swing training device.  
     
     
         5 . The swing training device according to  claim 1  or  3 , wherein the pendulum part has a cylindrical shape.  
     
     
         6 . The swing training device according to  claim 1  or  3 , wherein the pendulum part has a solid shape or a hollow shape.  
     
     
         7 . The swing training device according to  claim 1  or  3 , wherein the pendulum part is made of thermoplastic elastomer, thermoplastic resin, thermoplastic vulcanizates (TPV) or rubber.  
     
     
         8 . A swing training device for reforming the swing comprising: 
 a rigid shaft part having a grip part formed as grip on the surface;    a pendulum part extending from the forward end of the shaft and having flexibility and restoring elasticity for restoration to a substantially straight state; and    a head part secured to the forward end of the pendulum part.    
     
     
         9 . A swing training device for reforming the swing, comprising: 
 a grip part serving as grip;    a shaft formed at least in the inside of the grip part;    a pendulum part formed such as to extend from the forward end of the shaft and having flexibility and restoring elasticity for restoration to a substantially straight state; and    a head part secured to the forward end of the pendulum part.    
     
     
         10 . The swing training device according to  claim 8  or  9 , wherein the head part is an elastic weight member.  
     
     
         11 . The swing training device according to  claim 8  or  9 , wherein the head part has a cylindrical shape or a global shape, is longitudinally substantially perpendicular to the pendulum part, and is longitudinally symmetrically secured to a forward end mounting portion of the pendulum part.  
     
     
         12 . The swing training device according to  claim 8  or  9 , wherein the head part is made of urethane foam.  
     
     
         13 . The swing training device according to one of claims  1 ,  3 ,  8  and  9 , which has a length of about 76 to 117 cm.  
     
     
         14 . The swing training device according to one of claims  1 ,  3 ,  8  and  9 , which is used for reforming the golf club swing.  
     
     
         15 . The swing training device according to one of claims  1 ,  3 ,  8  and  9 , which is used for reforming the baseball bat swing.
