Golf swing trainer

Abstract

A golf swing trainer apparatus for straightening or otherwise improving a golf swing. The golf swing trainer may include a rod, a handle connected on one end of the rod, a bulb disposed on the other end of the rod, and a magnetic base positioned in the middle of the rod. An impact sliding block may be constrained to move on the rod between the bulb and the magnetic base, and may be held in a rest position by the magnetic base. When the user makes a stroke with the trainer apparatus, the impact sliding block may be forced downward from the magnetic base and may impact the bulb, making a sound to provide the user with feedback about their golf swing.

The following list of claims replaces any prior listing of claims: 
     
         1 . A golf swing trainer apparatus, comprising:
 a rod, the rod having an upper end and a lower end;   a handle disposed on the upper end of the rod, the handle having a grip;   a lower retaining element disposed on the lower end of the rod, the lower retaining element having a lower retaining element body portion and a counterweight head, the counterweight head fixedly facing in the direction of the upper end of the rod and being disposed around a circumference of the rod;   an upper retaining element disposed on the rod at a point between the lower and the upper end of the rod, the upper retaining element comprising a magnetic base facing in the direction of the lower end of the rod; and   an impact sliding block, the impact sliding block having a center hole through which the rod is disposed, the impact sliding block further being configured to move along a portion of the rod between the counterweight head of the lower retaining element and the magnetic base of the upper retaining element, wherein each of the counterweight head of the lower retaining element and the magnetic base of the upper retaining element have a larger cross-section than the center hole of the impact sliding block, the impact sliding block further having a sliding impact device coupled to an end of the impact sliding block facing in the direction of the counterweight head of the lower retaining element, wherein a flat surface of the sliding impact device is configured to contact a flat surface of the counterweight head.   
     
     
         2 . The golf swing trainer apparatus of  claim 1 , wherein the magnetic base comprises one or more magnetic elements, and wherein the impact sliding block has a plate of magnetic material disposed on an end of the impact sliding block that faces the magnetic base. 
     
     
         3 . The golf swing trainer apparatus of  claim 2 , wherein the magnetic elements comprise a plurality of rare earth magnets disposed around a circumference of the magnetic base. 
     
     
         4 . The golf swing trainer apparatus of  claim 1 , further comprising:
 a turning sleeve disposed around the magnetic base, the magnetic base having an external thread disposed around its external circumference, the turning sleeve having an internal thread disposed around its inner circumference, the internal thread of the turning sleeve and the external thread of the magnetic base configured to interlock;   wherein the turning sleeve and the magnetic base each have a lower end and an upper end, the lower end of each of the turning sleeve and the magnetic base facing in the direction of the lower retaining element, and the upper end of each of the turning sleeve and magnetic base facing in the direction of the handle; and   wherein the lower end of the turning sleeve extends past the lower end of the magnetic base.   
     
     
         5 . The golf swing trainer apparatus of  claim 4 , further comprising a limiting base, the limiting base being fixedly coupled to the magnetic base and extending above the upper end of the turning sleeve. 
     
     
         6 . The golf swing trainer apparatus of  claim 1 , wherein the lower retaining element comprises a decoration shell that is removably coupled to the counterweight head. 
     
     
         7 . The golf swing trainer apparatus of  claim 1 , wherein the sliding impact device is a metal sliding impact device, and the remaining portion of the impact sliding block is constructed from a nonmetallic material. 
     
     
         8 . The golf swing trainer apparatus of  claim 1 , wherein the lower retaining element comprises a bulb having a lower end and an upper end, a metal fixed impact sleeve fixed on the upper end of the bulb, and a metal sliding impact sleeve, the metal impact sleeve having an upward-facing impact part, the metal sleeve being connected to the bulb by a spring;
 wherein each of the metal fixed impact sleeve and the metal sliding impact sleeve are disposed around the circumference of the rod, and wherein the metal fixed impact sleeve and metal sliding impact sleeve are disposed sequentially on the rod and held apart by the spring.   
     
     
         9 . The golf swing trainer apparatus of  claim 1 , wherein the rod has a molded grip configured to hold the hands of the user in an optimal swing position. 
     
     
         10 . The golf swing trainer apparatus of  claim 1 , wherein the position of the upper retaining element on the rod is adjustable.
