Golf swing practice device

Abstract

An improved golf swing practice device is composed of a base frame, a guide hoop mounted on the base frame and having a trajectory on the same plane, a guide rail slidably mounted on the guide hoop, the guide rail being parallel to the plane that the guide hoop is positioned and having an extending direction substantially corresponding to the diametrical direction of the guide hoop, a slide member slidably mounted on the guide rail, and a training golf club having a distal end pivotably mounted on a rear end of the slide member to define an imaginary club head. Accordingly, the golfer can stand behind the guide hoop and hold the training golf club to perform swing actions. A position that the imaginary club head is positioned is controlled to move on a swing plane, such that the present invention effectively helps the golfer to perform swing actions.

1 . A golf swing practice device comprising: 
 a base frame;    a guide hoop mounted on said base frame, a standing space being defined at a rear side of said guide hoop for the golfer's standing and performing swing actions, a trajectory of said guide hoop being positioned on the same plane and facing the standing space and sloping with its top side facing upwards and forwards;    a guide rail slidably mounted on said guide hoop, said guide rail having a long axle parallel to said plane that said guide hoop is positioned;    a slide member slidably mounted on said guide rail; and    a training golf club having an end pivotably connected to a rear end of said slide member and the other end provided for the golfer's holding.    
   
   
       2 . The practice device as defined in  claim 1 , wherein said guide hoop angle-adjustably mounted on said base frame.  
   
   
       3 . The practice device as defined in  claim 1 , wherein said guide hoop is elliptical in shape and has a long axle, said long axle having two ends corresponding to left and right ends of said base frame.  
   
   
       4 . The practice device as defined in  claim 3 , wherein said guide rail is connected to said guide hoop at an end thereof and is correspondingly positioned inside an ellipse defined by said guide hoop, a position that said training golf club is pivotably connected with said slide member abutting the ground for a distance when said guide rail slides down to a lowest point of said guide hoop.  
   
   
       5 . The practice device as defined in  claim 1 , wherein said guide hoop is circular.  
   
   
       6 . The practice device as defined in  claim 1 , wherein said guide hoop is elliptical and has a long axle, said long axle having two ends corresponding to left and right sides of said base frame, two arched sections being formed at a top bilateral side of said guide hoop, the curvature of said two arched sections being not identical to that of the whole guide hoop, the trajectory of said guide hoop substantially corresponding to that of a golf club head during a general swing action.  
   
   
       7 . The practice device as defined in  claim 1 , wherein said guide hoop has an I-shaped cross-section to form two opposite channels and opposite bilateral sides respectively facing forwards and backwards, said guide hoop having a front side connected with said base frame; said guide rail comprises two crank-like members, said two crank-like members respectively extending into said two channels of said guide hoop, each of distal ends of said crank-like members being pivotably disposed with a plurality of rollers, said rollers engaging against the peripheries of said channels.  
   
   
       8 . The practice device as defined in  claim 1 , wherein said guide rail has a T-shaped channel extending along the long axle thereof, said T-shaped channel having an opening facing backwards; said slide member comprises a head portion received in said T-shaped channel and a body portion extending from said head portion towards outside of said T-shaped channel, said head portion having a plurality of rollers, said rollers engaging against an inner periphery of said T-shaped channel; said training golf club is pivotably connected to a rear end of said body portion.  
   
   
       9 . The practice device as defined in  claim 1 , wherein said head portion of said slide member is pivotably connected with a connector at a rear end thereof; said training golf club is connected with said connector at an end thereof.
