Systems and methods for golf swing training

Abstract

A golf swing training device may comprise a first elongate member and a second elongate member each coupled at and extending orthogonally from a junction, wherein the second elongate member is shorter than the first elongate member, wherein a distal end of the second elongate member is sharply tapered to a point.

What is claimed is: 
     
         1 . A golf swing training device, comprising:
 a first elongate member and a second elongate member each coupled at and extending orthogonally from a junction, wherein the junction includes a frangibility feature, wherein in response to applying an impact force to the first elongate member, the first elongate member is separated from the junction with the second elongate member by shearing at the frangibility feature.   
     
     
         2 . The golf swing training device of  claim 1 , wherein the ratio of the length of the first elongate member to the second elongate member is about 1:1.2. 
     
     
         3 . The golf swing training device of  claim 1 , wherein an interior angle defined by an intersection between the center lines of first elongate member and the second elongate member is between 85° and 95°. 
     
     
         4 . The golf swing training device of  claim 1 , further comprising a flanged portion projecting radially from the second elongate member. 
     
     
         5 . The golf swing training device of  claim 4 , wherein the flanged portion includes a frustoconic al portion. 
     
     
         6 . The golf swing training device of  claim 4 , wherein the flanged portion is removable. 
     
     
         7 . The golf swing training device of  claim 4 , wherein the flanged portion is traversable along the second elongate member in response to a traversing force. 
     
     
         8 . The golf swing training device of  claim 1 , wherein the second elongate member comprises a detent. 
     
     
         9 . The golf swing training device of  claim 1 , wherein the junction includes a web portion extending between the first elongate member and the second elongate member. 
     
     
         10 . The golf swing training device of  claim 1 , wherein a distal end of the second elongate member is sharply tapered to a point. 
     
     
         11 . The golf swing training device of  claim 1 , wherein the frangibility feature includes at least one of a cutout portion or a shear line. 
     
     
         12 . A golf swing training device, comprising:
 a first elongate member and a second elongate member each coupled at and extending orthogonally from a junction, wherein the second elongate member comprises a flanged portion, wherein each of the first elongate member, the second elongate member, the junction, and the flanged portion are monolithic, wherein the junction includes a frangibility feature, and wherein in response to applying an impact force to the first elongate member, the first elongate member is separated from the junction with the second elongate member by shearing at the frangibility feature.   
     
     
         13 . The golf swing training device of  claim 12 , wherein the flanged portion projects radially from the second elongate member, the flanged portion including a frustoconical portion. 
     
     
         14 . The golf swing training device of  claim 12 , wherein the junction includes a web portion extending between the first elongate member and the second elongate member. 
     
     
         15 . The golf swing training device of  claim 12 , wherein the first elongate member comprises one of a circular cross section, an elliptical cross section, a lenticular cross section, or a rectangular cross section. 
     
     
         16 . A method of providing golf swing feedback, comprising:
 aligning a first elongate member of a swing training device;   applying an insertion force to a second elongate member of the swing training device and, in response, inserting a distal end of the second elongate member below a substrate; and   applying an impact force to the first elongate member and, in response to the impact force, shearing the first elongate member from a junction between the first elongate member and the second elongate member.   
     
     
         17 . The method of  claim 16 , further comprising removing the insertion force in response to at least one of a tactile feedback, a visual feedback, or contacting a flanged portion with the substrate. 
     
     
         18 . The method of  claim 17 , further comprising selecting a desired height of the first elongate member above a golf ball.
