Abstract
Description
- The present disclosure relates to a golf putter for practice(hereinafter, referred to as "golf practice putter"), and more particularly, to a golf practice putter, in which a hitting face is capable of being interchangeably used and a right-handed user or a left-handed user is capable of easily use the putter, so that putting practice for precisely putting a golf ball placed on a putting green into a hole can be efficiently performed.
- In general, a putter is an iron club for putting and is used to directly hit a ball on a green toward a hole. The term, putting, means an act of hitting a ball using a putter.
- In the above-mentioned putting, direction and distance are important for successful putting, but what is required most is a correct putting posture. In order to have the correct putting posture, it is necessary to learn the feeling of the posture through numerous exercises over a long period of time.
- In this case, the correct putting posture refers to a posture for causing a putter and a golfer's hands holding the putter to perform a pendulum movement around the golfer's head during swing and causing the putter head to impact the ball at the lowest point of the pendulum movement. The ball will be sent to the desired position only when the ball is hit with the posture described above.
- When the wrist is bent or the body is shaken during the swing, a correct pendulum movement is not performed. Thus, the ball is impacted at an improper position and the ball will not be sent to the desired position.
- These problems may be somewhat solved by practicing putting using a practice putter.
- As a prior art, a putter for golf practice is disclosed in Korean Utility Model No.

FIG. 3 is an exploded perspective view illustrating a first embodiment of the present disclosure,FIGS. 4A to 4C are perspective views illustrating different embodiments of a hitting member illustrated inFIG. 1 , andFIG. 5 is a cross-sectional view illustrating a coupling state of the golf practice putter illustrated inFIG. 3 . - As illustrated in
FIGS. 3 to 5 , a golf practice putter according to a first embodiment of the present disclosure includes aputter head 20 having aputter face 24 at a lower end of ashaft 10 having a grip at an upper end thereof, and a hittingmember 30 is detachably coupled to theputter head 20. - This will be described in more detail.
- A through
hole 22 is formed in theputter head 20 to be stepped such that afastening bolt 40 upwardly passes through the throughhole 22 from the bottom face of theputter head 20, and acutout portion 26 is formed in theputter face 24 corresponding to the throughhole 22 to open a portion of theupper face 23 of theputter head 20 in a hitting direction. - Forming the through
hole 22 to be stepped is to prevent the head of the fasteningbolt 40 from protruding from the bottom face of theputter head 20 when thefastening bolt 40 is coupled to the hittingmember 30 through the throughhole 22. - It is desirable to form the through
hole 22 and thecutout portion 26 in the middle portion of theputter head 20. - The hitting
member 30 is configured to be selectively coupled to or separated from theputter head 20, and is formed to have the shape of a golf ball as illustrated inFIG. 3 in a size, which is the same as or similar to that of the golf ball. The hittingmember 30 has a spherical or flat hittingface 34 on the outer peripheral face thereof, aseating face 32 seated on theupper face 23 of theputter head 20, and asupport face 32A formed on one side of theseating face 32 in a stepped form so as to be supported by theedge 23A of theupper face 32 when theseating face 32 is seated on theupper face 23. Theseating face 32 is provided with a screw-fastening groove 32B having female threads such that thefastening bolt 40 is coupled thereto. - The hitting
member 30 described above is interchangeably coupled to theputter head 20 by thefastening bolt 40 in the state of being seated on theupper face 23 such that a part of the hittingface 34 protrudes beyond theputter face 24 through thecutout portion 26. In addition, even if thefastening bolt 40 is fastened to the screw-fastening groove 32B through the throughhole 22 from the bottom face of theputter head 20, the head of thefastening bolt 40 does not protrude from the bottom face of theputter head 20 since the head of thefastening bolt 40 is seated in the stepped throughhole 22. - Meanwhile, the hitting
face 34 of the hittingmember 30 is formed as aspherical hitting face 34A formed in a curvature, which is the same as the golf ball or aflat hitting face 34B formed in a plane shape. When aflat hitting face 34B is formed as the hittingface 34, it is desirable to provide multiple hittingmembers 30 for respective sizes of flat hitting faces 34B. That is, when multiple hittingmembers 30 having different flat hitting surfaces 34B of different sizes are provided, a user may select a hittingmember 30 having theflat face 34B of a desired size, and may use the hittingmember 30 by coupling the hittingmember 30 to theputter head 20. - The action of the golf practice putter according to the first embodiment of the present disclosure, which is configured as described above, will be described.
- The user may select hitting
members 30 having different hitting faces 34. For example, the user may select and a hittingmember 30 having aspherical hitting face 34A to theupper face 23 of theputter head 20, or may select and couple a hittingmember 30 having aflat face 34B and couple the hittingmember 30 to theupper face 23 of theputter head 20. That is, the user selects a hittingmember 30 having a desired hittingsurface 34 and couples the hittingmember 30 to theputter head 20 using thefastening bolt 40. - Next, when the hitting
member 30 is coupled to theputter head 20, since the hittingface 34 protrudes beyond the hittingface 24 of theputter head 20 in the hitting direction through thecutout portion 26, the user is capable of performing putting practice for hitting a golf ball with the hittingmember 30, as illustrated inFIG. 6 . - Since it is possible to select one of a hitting
member 30 having aspherical hitting face 34A and a hittingmember 30 having a flat hitting face 34B and to use the selected one by coupling the selected one to theputter head 20, the user may perform putting practice more efficiently using various hitting faces. - In addition, since the
seating face 32 of the hittingmember 30 is seated on theupper face 23 of theputter head 20, thesupport face 32A is supported on the edge of theupper face 23, and thefastening bolt 40 is fastened to thefastening groove 32B through the throughhole 22, the hittingmember 30 and theputter head 20 are maintained in the strongly coupled state, and thus the hittingmember 30 does not move during putting practice. Further, since thesupport face 32A is supported by theedge 23A of theupper surface 23, it is possible to stably hit the golf ball without movement of the hittingmember 30. - In the accompanying drawings,
FIG. 7 is an exploded perspective view illustrating a second embodiment of the present disclosure,FIG. 8 is a cross-sectional view illustrating the coupled state of the golf practice putter illustrated inFIG. 7 , andFIGS. 9A and 9B are plan views illustrating the state in which the hitting direction of the golf practice putter illustrated inFIG. 7 is changed. - As illustrated in

That is, the outer peripheral surface of each of the hittingmembers spherical hitting face 320 in one part, and different flat hitting faces 340 are formed in the other parts, respectively. Forming multiple different hitting surfaces on one hitting member is to allow the user to select and use hitting surfaces having various sizes and shapes (spherical or flat shapes). - In addition,
position change units 500, which are configured to change the positions of thesecond hitting member 300B and thethird hitting member 300C, to select each of the spherical hitting faces 320 and each of the flat hitting faces 340, or to make the hitting faces 320 and 340 variable depending on whether a user is left-handed or right-handed, are provided on the opposite side faces of thesecond hitting member 300B, which face thefirst hitting member 300A and the third hitting member C, respectively, and on thefirst hitting member 300A and thethird hitting member 300C. - Each
position change unit 500 consists of a triangular tooctagonal connection member 510 having a predetermined length, and a triangular tooctagonal positioning groove 520 formed in each of the opposite side faces of thefirst hitting member 300A, thesecond hitting member 300B, and thethird hitting member 300C to be fitted on theconnection member 510. - The
polygonal connection members 510 and thepolygonal positioning grooves 520 will be described as being formed in a rectangular shape. The minimum number of theconnection members 510 is two.
This is to connect the different hitting members to the opposite sides of the centrally positioned hitting member, respectively. - The
first hitting member 300A, thesecond hitting member 300B, and thethird hitting member 300C may be made of a material, which is the same as that of the golf ball, a metal material, or a synthetic resin material. - In addition, a through hole may be formed in each of the
connection members 510 so as to allow thecoupling rod 400 therethrough. - The action of the golf practice putter according to the second embodiment, which is configured as described above, will be described.
- As illustrated in
FIG. 8 , in the state in which theshaft 10 is coupled to thefirst hitting member 300A, thesecond hitting member 300B is located on one side face of thefirst hitting member 300A, thethird hitting member 300C is located on one side face of thesecond hitting member 300B, one end of one connection member 510A is fitted to thepositioning groove 520 of thefirst hitting member 300A, and the other end is fitted to thepositioning groove 520 formed in the one side face of thesecond hitting member 300B. In addition, one end of another connection member 510B is fitted to thepositioning groove 520 formed in the other face of thesecond hitting member 300B, and the other end is fitted to thepositioning groove 520 formed in one face of thethird hitting member 300C. - Next, the
