Multi-purpose golf practice machine

Abstract

A multi-purpose golf practice machine is disclosed. The disclosed multi-purpose golf practice machine is for putting practice and comprises a base frame configured to be supported on the ground and a putting rail portion that has a curved shape and is installed to be connected to the base frame so as to guide a golf club along a putting trajectory, wherein the golf practice machine further comprises a connection joint portion that connects the base frame to the putting rail portion and allows changing a posture in various putting trajectory forms by rotating the putting rail portion back and forth with respect to the base frame.

What is claimed is: 
     
         1 . A multi-purpose golf practice machine for putting practice, comprising:
 a base frame configured to be supported on the ground; and   a putting rail portion that has a curved shape and is installed to be connected to the base frame so as to guide a golf club along a putting trajectory,   wherein the golf practice machine further comprises a connection joint portion that connects the base frame to the putting rail portion and allows changing a posture in various putting trajectory forms by rotating the putting rail portion back and forth with respect to the base frame.   
     
     
         2 . The multi-purpose golf practice machine of  claim 1 , wherein the connection joint portion comprises
 a rotation support portion fixedly installed on one side of the base frame;   a rotation shaft portion rotatably installed on the rotation support portion to enable adjustment of left and right rotation angle of the putting rail portion; and   a clip portion formed on an upper end of the rotating shaft portion and formed in an arch shape to secure a middle portion of the putting rail portion in a snap-fit manner while allowing the putting rail portion to be rotated forward and backward by an external force applied by a user.   
     
     
         3 . The multi-purpose golf practice machine of  claim 1 , wherein the connection joint portion comprises
 a fixed shaft portion fixedly installed on one side of the base frame; and   a clip portion formed on an upper end of the fixed shaft portion and formed in an arch shape to secure a middle portion of the putting rail portion in a snap-fit manner while allowing the putting rail portion to be rotated forward and backward by an external force applied by a user.   
     
     
         4 . The multi-purpose golf practice machine of  claim 1 , wherein the putting rail portion is configured with at least two putting rail bars, each formed in a curved shape and connected to each other, and is configured to be transformable into various putting trajectory forms. 
     
     
         5 . The multi-purpose golf practice machine of  claim 4 , wherein the at least two putting rail bars are provided with a coupling means that detachably couples two adjacent ends,
 the coupling means comprises a coupling recess formed on one end of two opposing ends of the two adjacent putting rail bars, a coupling protrusion formed on the other end of the two adjacent putting rail bars and configured to be inserted into and coupled to the coupling recess, and an attachment member, formed of any one of a Velcro means, a magnetic means, and a snap-fit means, configured to attach and detach the two opposing ends,   an inner circumferential surface of the coupling recess is provided with multiple rotation-restricting grooves at preset intervals, and   an outer circumferential surface of the coupling protrusion is provided with multiple rotation-restricting protrusions configured to be inserted into the rotation-restricting grooves to prevent relative rotation between the two putting rail bars when coupled.   
     
     
         6 . The multi-purpose golf practice machine of  claim 1 , further comprising a swing rail portion detachably coupled to each end of the putting rail portion and configured, together with the putting rail portion, to guide a golf club along golf swing trajectories. 
     
     
         7 . The multi-purpose golf practice machine of  claim 6 , wherein the swing rail portion comprises a first swing rail portion coupled to one end of the putting rail portion and configured to guide the golf club along backswing and downswing trajectories of the golf swing trajectories, and a second swing rail portion detachably coupled to the other end of the putting rail portion and configured to guide the golf club along follow-through and finish trajectories of the golf swing trajectories. 
     
     
         8 . The multi-purpose golf practice machine of  claim 7 , wherein the first swing rail portion is configured such that at least two first swing rail bars are detachably coupled to each other, and the second swing rail portion is configured such that at least two second swing rail bars are detachably coupled to each other, allowing them to be transformable into various swing trajectory forms. 
     
     
         9 . The multi-purpose golf practice machine of  claim 7 , wherein the first swing rail portion and the second swing rail portion are configured not to be connected to each other.
