Abstract

A putting practice machine according to one embodiment of the present invention includes a base member disposed behind a golf ball and having a preset height so that a putter hits the golf ball at a predetermined distance from the ground.

Description

[Technical Field]

[0001] The present invention relates to a putting practice machine that has a simple configuration and enables effective golf putting practice. [Background technology]

[0002] The putter is not only the club that a player uses most often in golf, but also has a direct impact on the player's score. Therefore, various types of practice equipment have been disclosed that allow players to practice putting strokes.

[0003] There are various theories regarding strokes for effective putting, but it is known that hitting the center of the ball upward with the center of the putter face is advantageous for rolling the golf ball.

[0004] Considering that a typical golf ball has a diameter of 42.7 mm, when using a typical putter, a player must strike the ball in the center of the putter head while keeping the putter at a certain distance from the ground. Furthermore, to prevent distance loss, it is effective to strike the ball upward.

[0005] Generally, players prepare their putter to touch the ground to putt, which can cause the putter to drag too much on the ground during the stroke, resulting in the ball being hit on the top of the putter face.Even if a player prepares their putter while it is still touching the ground, if the putter is moved a certain distance from the ground during the stroke and the golf ball is hit, the ball can be hit in the center of the putter face instead of the top.

[0006] Conventional putting practice tools have the problem that the ball is placed on a member, the putter is placed on a member, or the ball and putter are placed on a member, resulting in practice in an environment that differs from actual putting.

[0007] Therefore, there is a need for a training device that can effectively practice upward strokes at the center of the putter with a simple structure. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to provide a solution to the above problems.

[0038] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the concept of the present invention is not limited to the disclosed embodiments, and a person skilled in the art who understands the concept of the present invention may easily propose other inventions or other embodiments within the concept of the present invention by adding, changing, or deleting other components within the same concept, which would also be considered to be within the concept of the present invention.

[0039] Figure 1 is an oblique view showing a putting practice machine of the first embodiment of the present invention, Figure 2 is an oblique view showing the side of the putting practice machine of the first embodiment of the present invention and the path along which the putter moves, Figure 3 is a diagram showing the state in which the first side member and the second side member are connected to the putting practice machine of one embodiment of the present invention, and Figure 4 is a diagram for explaining the state in which the base member of the putting practice machine of one embodiment of the present invention is used.

[0040] 1 and 4, the golf training device of this embodiment includes a base member 10, a first side member 20, and a second side member 30. As shown in FIG.

[0041] The base 10 functions to enable the user to strike the golf ball 2 at a certain distance from the bottom surface when stroking the putter 1.

[0042] The distance a typical putter must be spaced from the ground to hit the center of the golf ball varies depending on the size of the golf ball and the size of the putter. The diameter of a typical golf ball is approximately 42.7 mm. For putters, the center is 13 mm from the bottom, although this varies depending on the type. Therefore, in order to hit the center of the golf ball with the center of the putter, it is most effective to perform a stroke with the putter about 7 to 8 mm off the ground.

[0043] In this embodiment, when practicing strokes with a base member 10 having a preset height placed behind the golf ball 10, the putter 1 must be spaced a certain distance from the bottom surface before making a stroke, otherwise the base member 10 will not strike the golf ball 2 accurately.

[0044] That is, the set height of the base member 10 in this embodiment is 7 to 8 mm, and the user can practice hitting the center of the golf ball 1 with the center of the putter 1 through stroke practice so that the user can hit the golf ball 2 without interference from the base member 10.

[0045] The width of the base member 10 in the left-right direction is not limited, but in this embodiment, it is preferably formed to be longer than the width of a typical putter in the left-right direction. As a result, when the first side member 20 and the second side member 30 described below are attached to the base member 10, it is possible to practice hitting the ball at the center point based on the left-right direction of the putter 1 during a stroke.

[0046] Furthermore, when the base member 10 is formed in a rectangular bar shape, the alignment of the putter face can be checked by making the base member 10 parallel to the putter face.

[0047] The front-to-rear width of the base member 10 is not limited, but is preferably narrower than the front-to-rear width of a typical putter. In particular, when the golf ball 2 is placed in front of the base member 10, if the width is such that the base member 10 can be positioned under the golf ball 2, addressing the putter 1 with a short distance between the golf ball 2 and the putter 1 is possible. Therefore, practice can be performed under the same conditions as when actually putting.

[0048] Furthermore, the width L2 in the front-rear direction and the width L1 in the up-down direction of the base member 10 can be formed to be different from each other. Therefore, as shown in Figure 4, the base member 10 can be rotated to set different heights.

[0049] A first recess 11 may be formed on the entire surface of the base member 10. The first recess 11 is formed in a shape corresponding to the outline of the golf ball 2. Therefore, when the golf ball 2 is placed on the front surface of the base member 10, the first recess 11 allows the golf ball 2 to be positioned rearward, allowing the user to address the ball 2 with a shorter distance between the putter 1 and the putter.

[0050] A second recess 12 is formed on the rear surface of the base member 10. The second recess 12 is formed to have an inclined surface that slopes downward from the top surface of the base member to the rear end. Therefore, when the user performs a stroke, it can be guided to perform an upward impact from the bottom to the top.

[0051] A third depression 14 is formed in the lower front surface of the base member 10. The third depression 14 has a downwardly inclined surface, similar to the second depression 12. Therefore, as shown in FIG. 4, when the base member 10 is positioned so that the third depression 14 is located at the top, it can induce an upward hit of the putter 1.

[0052] The scales 13, 15 may be provided in various shapes on the top and front surfaces of the base member 10. Therefore, the user can check the alignment by comparing the scales 13, 15 with the front surface of the putter 2 during the address process.

[0053] Furthermore, in the case of various conventional putting practice devices, practice is conducted with the golf ball positioned on the device, the putter positioned on the device, or both the golf ball and the putter positioned on the device. However, in actual putting, the golf ball is positioned on the ground, with no components between the putter and the ground. That is, when using the putting practice device of the present invention, the base member 10 is positioned between the golf ball 2 and the putter 1, and practice is possible with the golf ball 2 positioned on the ground, with no components between the putter 1 and the ground, similar to actual putting conditions. Therefore, there is an advantage in that practice can be conducted under the same conditions as actual putting.

[0054] The first side member 20 and the second side member 30 are connected to both ends of the base member 10, and the putter 1 passes between the first side member 20 and the second side member 30 during a stroke. Therefore, it is possible to practice hitting the golf ball 2 in the center of the putter 1 based on the left-right direction.

[0055] In this embodiment, the first side member 20 and the second side member 30 are formed in a rod shape and can be detachably coupled to the base member 10. Therefore, a user can selectively couple the first side member 20 and the second side member 30 of various shapes having different lengths or widths to the base member 10.

[0056] Various known methods may be used to connect the first and second side members 20 and 30 to the base member 10. For example, if grooves are formed in the base member 10, the rod-shaped first and second side members 20 and 30 may be connected in a fitted manner.

[0057] In this embodiment, magnets 21, 31 are provided on the lower portions of the first side surface member 20 and the second side surface member 30. Therefore, if the base member 10 is made of a material that can be bonded by magnetic force, such as iron, the magnets 21, 31 can be bonded to the base member 10 by magnetic force.

[0058] On the other hand, the height of the first side surface member 20 is set to a height that does not interfere with the shaft of the putter 2 when the user addresses the ball at the center of the base member 10 .

[0059] In other words, using the putting training machine of this embodiment, a user can practice hitting a golf ball in the center based on the up-down and left-right directions of the putter 1 with the first side member 20 and the second side member 30 connected to the base member 10, or can practice hitting a golf ball in the center based on the up-down direction of the putter 1 with the first side member 20 and the second side member 30 separated from the base member 10.

[0060] Furthermore, in this process, by placing the golf ball 2 in the first recessed groove 11, the distance between the golf ball 2 and the putter 1 can be reduced during address, allowing practice while making an address similar to the actual one, and by forming the second recessed groove 12, it is also possible to practice an upward hit during the stroke process.

[0061] FIG. 5 is a perspective view of a putting training machine according to a second embodiment of the present invention, and FIGS. 6 and 7 are diagrams for explaining various usage states of the putting training machine according to the second embodiment of the present invention.

[0062] 5 to 7, the putting training machine according to the second embodiment of the present invention includes a base member 10, a first side member 120, and a second side member .

[0063] The overall configuration of the base member 10 is the same as that of the first embodiment described above, and therefore the following description will be omitted.

[0064] The first side member 120 and the second side member 130 of this embodiment are formed to have a fixed length, unlike in the first embodiment. A plurality of coupling portions are formed on the first side member 120 and the second side member 130. The coupling portions may employ various coupling structures that can couple the first side member 120 and the second side member 130 to the base member 10, and in this embodiment, they are formed with a plurality of magnets 121, 131, as in the first embodiment.

[0065] Specifically, in this embodiment, three magnets 121, 131 are arranged at regular intervals, and as shown in Figures 6 and 7, by changing the positions at which the first side member 120 and the second side member 130 are attached to the base member 10, it is possible to train strokes with various trajectories in parallel.

[0066] Other configurations of this embodiment are the same as those of the above-described embodiment, and therefore the following description will be omitted.

[0067] FIG. 8 is a perspective view of a putting training machine according to a third embodiment of the present invention, and FIGS. 9 and 10 are diagrams illustrating the process of a user visually checking the alignment of a putter using the putting training machine according to the third embodiment of the present invention.

[0068] 8 to 10, the putting training device of this embodiment includes a base 10, a first side member 20, and a second side member 230. As shown in FIG.

[0069] The base 10 and the first side surface member 20 are the same as those in the first embodiment described above, and therefore the following description will be omitted.

[0070] The second side member 230 is connected to the base member 10 by a magnet 231 and includes a first part 232 that is elongated in the vertical direction, and a second part 233 that extends from the first part 232 and is elongated in the horizontal direction of the putter 1.

[0071] The height of the first part 232 and the length of the second part 233 are formed so that the putter can pass between the base 10, the first side member 20, and the second side member 230 during a stroke.

[0072] Meanwhile, the second side member 230 has a structure that allows it to be selectively attached to the base member 10, so that the second side member 230 of a size corresponding to various types of putters can be selectively attached to the base member 10 for practice.

[0073] In other words, when using the putting training machine of this embodiment, as described above, the user has the advantage that not only can he practice hitting the center based on the up-down direction of the putter 1 and the center based on the left-right direction of the putter 1, but he can also train to prevent hitting the upper center of the golf ball.

[0074] Generally, depending on the dominant eye, there may be a difference between the actual position of the putter 1 and the position of the putter 1 perceived by the user. Therefore, it is very important to recognize the difference between the alignment of the putter 1 based on the dominant eye of the user and the actual position of the putter 1, and to perform accurate alignment accordingly.

[0075] 9, it is possible to check whether the alignment in the front-rear direction is correct by comparing the position of the scale 13 of the base member 10 with the position of the second part 233 at address. In particular, if the width of the second part 233 in the front-rear direction is narrower than the width of the base member 10 in the front-rear direction, it is possible to more effectively check the position of the scale 13 with the second part 233.

[0076] In addition, a plurality of scales 234 may be formed on the second part 233 in the left-right direction of the putter 1. Therefore, as shown in Fig. 10, the left-right alignment can be confirmed by comparing the scales 13 on the base member 10 with the scales 234 on the second part 233.

[0077] As a result, in this embodiment, the second side member 230 including the second part 233 located on the top of the putter 1 during a stroke not only allows the user to train to prevent excessive upward hitting or hitting the top center of the ball during a stroke, but also has the advantage of being able to check whether the putter 1 is aligned correctly when addressing the ball.

[0078] In addition, the second part 233 may be formed with a fourth recess 233a having an inclined surface that slopes downward from the front surface of the second part 233. This allows the putter 1 to effectively guide an upward hit.

[0079] 11 is a perspective view of a putting training device according to a fourth embodiment of the present invention. Referring to FIG. 11, the putting training device of this embodiment includes a base 10, a first side member 20, and a second side member 330.

[0080] The base 10 and the first side surface member 20 are the same as those in the first embodiment described above, and therefore the following description will be omitted.

[0081] The second side member 330 of this embodiment is connected to the base member 10 by a magnet 331, and includes a first part 332 and a second part 333 that is formed long in the left-right direction of the putter 1 and is movably connected to the first part 232.

[0082] The first part 332 includes a fixed member 332a and a movable member 332b that is connected to the fixed member 332a so as to be movable in the up-down direction. The movable member 332b may be formed to be elongated in the up-down direction, and in this embodiment, is formed by being bent toward the first side surface member 10.

[0083] That is, in this embodiment, the vertical height can be adjusted by moving the moving member 332b, and the horizontal width can be adjusted by moving the second part 333. Therefore, there is an advantage that it can be used for putters 1 of various sizes and shapes.

[0084] Fig. 12 is a perspective view of a putting training device according to a fifth embodiment of the present invention, and Fig. 13 is a cross-sectional view of the putting training device according to the fifth embodiment of the present invention. Referring to Figs. 12 and 13, the putting training device of this embodiment includes a base member 110 and a plurality of second side members 230, 230'.

[0085] The base member 110 includes a body 111 and an extension 112 formed by extending from the other end of the body 111. The body 111 of this embodiment may be formed in the same shape as the base member 10 of the above-described embodiment, and the extension 112 is formed at the other end of the body 111.

[0086] A plurality of second side members 230, 230' are provided and are coupled to the other end of the body 111 and the extension 112. The second side members 230, 230' in this embodiment may be the second side members of the third embodiment or the second side members of the fourth embodiment.

[0087] Therefore, when the second side member of the third embodiment is applied, if the height d1 of the front side member 230 is formed higher than the height d2 of the rear second side member 230', the configuration shown in Figure 13 can be arranged to induce an upward hit of the putter 1.

[0088] When the shape of the side member 330 of the fourth embodiment is applied, the upward hit of the putter 1 can be induced by adjusting the distance that the moving member 332b moves from the fixed member 332a.

[0089] FIG. 14 is a perspective view of a putting training machine according to a sixth embodiment of the present invention.

[0090] Referring to FIG. 14, the putting training device of this embodiment includes a base member 210 and a plurality of first and second side members.

[0091] The base member 210 includes a body 211 and extensions 212 formed to extend in the front-rear direction from one end and the other end of the body 211 .

[0092] Therefore, the user can assemble the golf club in a variety of forms that allow for various stroke practice by selectively combining the various first and second side members described above with the body 211 and the extension 212.

[0093] FIG. 15 is a perspective view of a putting training machine according to the seventh embodiment of the present invention.

[0094] Referring to FIG. 15, the putting training device of this embodiment includes a base member 310 and a plurality of first and second side members.

[0095] The base member 310 includes a body 311, extensions 312 extending in the front-to-rear direction from one end and the other end of the body 311, and protrusions 313 formed on the extensions 312 extending forward of the body 311 in directions opposite to each other.

[0096] The protrusions 313 may be formed at the same height as the body 311 or at a height higher than the body 311. Therefore, the user can practice strokes so that the putter 1 maintains a constant height from the ground even after hitting the golf ball 2 with the putter 1. The protrusions 313 may be formed at a constant distance apart so that the golf ball 2 can pass between the protrusions 313.

[0097] Therefore, the user can assemble the golf club in a variety of forms that allow for various stroke practice by selectively connecting the various first and second side members to the body 311 and the extension 312.

[0098] FIG. 16 is a perspective view of a putting training machine according to an eighth embodiment of the present invention.

[0099] Referring to FIG. 16, the putting training device of this embodiment includes a base member 410, a first side member 420, and a second side member 430.

[0100] In this embodiment, at least one of the first side member 420 and the second side member 430 is connected to the base member 410 so as to be movable in the left-right direction. Therefore, the left-right width of the space through which the putter passes can be adjusted. Therefore, it can be used universally for putters of various sizes, and the difficulty of practice can be adjusted by adjusting the width.

[0101] The base member 410 of this embodiment includes a body 411 and an extension 412 .

[0102] The body 411 may be formed in a shape similar to that of the above-described embodiment, but in this embodiment, guide grooves 411a and 411b are formed to slidably couple the first side member 420 and the second side member 430.

[0103] In this embodiment, the guide grooves 411a and 411b are recessed into the upper surface of the base member 411, but are not limited thereto as long as the first guide member 420 and the second guide member 430 are movably coupled.

[0104] The extensions 412 are formed to extend from the ends of the body 411 to enable stable support of the base member 410, and in this embodiment, four extensions 412 are formed in the front-rear direction at both ends of the body 411.
