Putting training aid

Abstract

To provide a compact putting training aid for enabling a user to train putting with a normal putter.SOLUTION: A putting training aid 1 includes: an isosceles triangular main body 2; a reference surface 24 positioned on a bottom surface part of the isosceles triangle; and a laser beam oscillation device 3 incorporated in the main body 2. When a putter face Paf of a putter is allowed to have surface-contact with the reference surface 24, a direction of the isosceles triangular main body 2 indicates an advance direction of a ball when performing putting. An extension line of an indication line 25 displayed on an upper surface of the main body 2 indicates a movement direction of the ball. When the laser beam oscillation device 3 is turned on, an irradiation position of the laser indicates the advance direction of the ball. The putting training aid is used while a stance is determined, thereby to recognize a difference between a sensorily determined stance and the actual movement direction of the ball.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a putting practice aid, and more particularly to a putting practice aid for correcting the putting direction of a player when deciding on a putting stance. [Background technology]

[0002] In golf, the winner is determined by the number of times a player hits the ball from the tee until it finally lands in the cup. The number of putts on the green where the cup is cut is said to be a major factor in determining victory or defeat. For this reason, putting practice tends to be popular. While golf practice requires a driving range with a certain amount of space to practice hitting shots with drivers and irons, putting practice can be done in a small space, even indoors at home. In such putting practice, the following tools have been proposed to improve the effectiveness of practice. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Application Publication No. 6-57368 [Patent Document 2] Patent Publication No. 2000-288146 [Patent Document 3] JP 2005-253559 [Patent Document 4] Utility Model Application Publication No. 8-71191 [Patent Document 5] Utility Model Registration No. 3042356 [Patent Document 6] JP 2003-305148 A [Patent Document 7] Patent Publication No. 2019-216782 Summary of the Invention [Problem to be solved by the invention]

[0004] When putting, first decide on your stance. If the putting line is a straight line, as shown in Figure 11, imagine a straight line L0 connecting ball B and cup C, and decide your stance so that the toes A1 and A2 of both feet are on a line L1 parallel to line L0. Then, align the putter face F with ball B, and make a stroke along line L0 while maintaining the putter face F perpendicular to line L0 connecting ball B and cup C. Even when taking a shot following this procedure, ball B may not necessarily head toward cup C, as shown by the lines Sh1 and Sh2 that indicate the shot direction.

[0005] There are several reasons for this, one of which is when the stance that was initially decided upon is not parallel to the line L0 connecting ball B and cup C, or when the putter face F is not held perpendicular to the line L0. These are cases where the player is not aware of it, but the stance position is not as intended, or the putter face F is not positioned as intended. Possible causes include, for example, skeletal distortion, bad habits acquired during practice, or visual impairment in either eye.

[0006] In such cases, no tool has been proposed to quantitatively detect problems in the player's stance or the settings of the putter face F. Patent documents 1 to 3 listed in the above prior art documents are designed to correct the stroke direction in the putter itself, and are putters that can be used for putting practice but cannot be used in actual competitions. The putters described in Patent Documents 4 to 6 also have a built-in laser device and are designed to allow for more accurate stroke practice, but these cannot be used in actual competitions. Patent Document 7 describes a practice aid for practicing putting with a putter that can be used in competitions, but it is large in size and not suitable for carrying to a practice range.

[0007] An object of the present invention is to provide a putting practice aid that is compact and allows practicing putting with a normal putter. [Means for solving the problem]

[0008] The putting training aid of the present invention solves the above problems and has the following features: A putting training aid that is placed on the impact direction side of the putt after the player has finished addressing the putt, The main body and a reference portion provided on the putter side of the main body and disposed along the putter face to detect the orientation of the putter face; an indicator provided along a direction perpendicular to the putter face detected by the reference portion; By checking the direction the indicator is pointing, the player can accurately predict the direction the ball will actually roll when putting.

[0009] The putting practice aid of the present invention also includes: A putting training aid that is placed on the impact direction side of the putt after the player has finished addressing the putt, The main body and a reference portion provided on the putter side of the main body and disposed along the putter face to detect the orientation of the putter face; a laser oscillator for generating a laser beam that is irradiated in a direction perpendicular to the putter face detected by the reference unit; With this configuration, the player can accurately predict the direction in which the ball will actually roll when putting, based on the direction in which the laser light is emitted.

[0010] Furthermore, by having a through hole located on the axis of the indicating part and through which the rotation axis of the main body is inserted, the main body can swing around the rotation axis and easily change its orientation, so that the reference part can detect the orientation of the putter face.

[0011] Furthermore, by providing the insertion hole near the center of gravity of the main body, the main body can be made to swing even more easily. Furthermore, by providing a rotation shaft upright on a base positioned below the main body, the main body can be further easily swung.

[0012] By oscillating the laser irradiation direction along the vertical direction, the direction in which the laser light is being irradiated can be indicated by the laser light reflected on the ground. By providing a laser receiving member on the front or rear side of the cup, the direction in which the pole will actually roll can be more clearly indicated. [Effects of the Invention]

[0013] The putting training aid of the present invention allows you to practice putting with a regular putter, and helps you understand deviations in stance and putter face direction caused by skeletal distortions and habits, which can be useful in improving your putting technique.

[0015] One embodiment of the putting training aid of the present invention will be described in detail below. Figure 1 is an overall perspective view of the putting training aid 1 of the present invention, and Figure 2 is an exploded perspective view of the same. The putting training aid 1 comprises a main body 2, a laser beam oscillator 3, and a laser receiving member 4 that receives the laser beam generated by the laser beam oscillator 3. The main body 2 is a plate-like member formed into an isosceles triangle shape as a whole in a plan view, and the side of the base of the isosceles triangle serves as a reference surface 24, which serves as a reference portion. An indicator line 25, which serves as an indicator portion, is provided on the top surface of the main body 2 on the center line of the isosceles triangle, extending in a direction perpendicular to the reference surface 24, with the tip of the indicator line 25 reaching the apex 20 of the isosceles triangle. The base end of the indicator line 25 is connected to an axial hole 28. The axial hole 28 is preferably formed on the center line of the isosceles triangle at a position corresponding to the centroid of the isosceles triangle. A switch button 27 protrudes from the indicator line 25, and pressing this switch button 27 turns on / off the laser oscillation of the built-in laser beam oscillator 3.

[0016] A circular pseudo-ball portion 29 is provided at the center of the base of the isosceles triangle. The peripheral edges of this pseudo-ball portion 29 contact the reference surface 24, a guide line 25 passes through the center, and the diameter is the same as or similar to the diameter of a golf ball. A laser hole 26 through which a laser is irradiated is formed at the apex of the isosceles triangle in the main body 2. Because the overall shape of the main body 2 is an isosceles triangle in a plan view, the orientation of the main body 2 directly indicates the direction in which the ball will be hit with the putter. Furthermore, the orientation of the guide line 25 extending from the reference surface 24 toward the tip also indicates the direction in which the ball will be hit with the putter. By providing such guide line 25, as shown in FIG. 3 , when viewing the tip 20 from the reference surface 24, it is easy to recognize the extension lines Q and Q0 of the guide line 25 as the trajectory of the ball rolling. In Figure 3, the extension line Q indicates that the ball's direction of putt is off to the right or left of the cup C as a result of measuring the ball's direction of putt using the putting training aid 1 of the present invention. In such cases, adjustments should be made during putting practice so that the stance position and address are determined so that the extension Q0 is aligned with the center of the cup C.

[0017] The main body 2 is constructed by stacking two identical plate-like members. The pair of plate-like members, an upper member 21 and a lower member 22, are stacked together with the lower surface 211 of the upper member 21 and the upper surface 221 of the lower member 22 facing each other and in contact. A storage groove 222, a light-transmitting groove 223, and an insertion hole 224 are formed on the same axis on the upper surface 221, which are the opposing surfaces. The rear end of the light-transmitting groove 223 is connected to the tip of the storage groove 222, and the tip of the light-transmitting groove 223 reaches the acute-angled tip of the isosceles triangular lower member 22. Insertion holes 225, through which fastening bolts 231 are inserted, are formed near both ends of the base of the isosceles triangle, and a similar insertion hole 225 is formed near the tip of the center portion.

[0018] On the other hand, the lower surface 211 of the upper member 21 is provided with the same configurations as the storage groove 222, light-passing groove 223, and insertion hole 224 formed on the upper surface 221, and these are formed in opposing positions when the upper member 21 and the lower member 22 are overlapped. An internal space is formed by matching the storage groove 212 (not shown) on the lower surface 211 with the storage groove 222, and a storage section is formed that accommodates the laser beam oscillator 3, which is the laser oscillator section. An internal space is formed by matching the light-passing groove 213 (not shown) on the lower surface 211 with the light-passing groove 222, and a laser passage through which the laser beam passes is formed, and its tip is the laser hole 26. An axial hole 28 is formed by matching the insertion hole 214 on the lower surface 211 with the insertion hole 224. A rotation shaft is inserted into this axial hole 28. On the lower surface 211, bolt holes 215 (not shown) are formed at positions facing the insertion portions 225 of the upper surface 221, and the tips of bolts 231 inserted through the insertion portions 225 are screwed into the bolt holes 215.

[0019] A switch hole 216 is formed on the indicator line 25 of the upper member 21, and a cylindrical switch member 27 is housed inside. The switch member 27 is held so as to be able to freely move in and out of the switch hole 216, and its lower end has a large diameter portion with a diameter larger than that of the switch hole 216 so as not to protrude outside. The switch hole 216 is located opposite the switch position of the housed laser beam oscillator 3, and is configured so that the switch button 31 of the laser beam oscillator 3 can be turned on / off from the outside via the switch member 27. When the laser beam oscillator 3 is used, a laser receiving member 4 is placed on the opposite side of the cup C.

[0020] When using the putting training aid 1 of the present invention for putting practice with this configuration, the position of a predetermined cup C is determined, assuming that the ball will be hit toward the cup. Next, the position where the ball will be hit toward the cup is determined. Then, as shown in FIG. 3, the putting training aid 1 of the present invention is placed at the position where the ball will be hit. The putting training aid 1 is positioned so that the pseudo-ball portion 29 overlaps with the position of the ball when actually putting. Then, the steps for hitting a ball toward a normal cup are carried out in order. That is, first, the stance is determined, and then the address is determined. Next, the putter face Paf of the putt Pa is placed on the reference surface 24. This causes the orientation of the putter face Paf to match the orientation of the reference surface 24. As a result, the direction in which the ball will be hit is indicated by the orientation of the indicator line 25 and the direction of the laser beam, depending on the orientation of the putter face Paf.

[0021] When using the laser beam oscillator 3, pressing the switch button 27 causes the laser beam position that appears on the laser receiving surface 41 of the laser receiving member 4 to indicate the ball's direction of impact. The distance between this position and the position of the cup C is the distance that needs to be corrected. The player takes a stance toward the center of the cup C and addresses the ball, but the player can quantitatively recognize the difference between the actual position measured by the putting training aid 1 of the present invention. By recognizing this distance, the player can correct the ball's impact direction in actual practice using that distance as the correction amount. For example, if the measured length is 5 cm to the right, the player can take a stance aiming for a position 5 cm to the left of the cup C and then putt. Alternatively, the player can adjust the position measured by the putting training aid 1 of the present invention during regular putting practice so that it coincides with the position measured by the putting training aid 1 after determining their stance without using the aid.

[0022] The practice method described above is a method of use when no pivot shaft is inserted through the pivot hole 28. The putting practice aid 1 shown in FIGS. 4 and 5 illustrates an embodiment in which a pivot shaft is inserted through the pivot hole 28. The putting practice aid 1 shown in FIG. 4 has a plate-shaped base 5 below the main body 2. The base 5 has a pedestal 51 and a pivot shaft 52 erected at the rear end of the pedestal 51. The pedestal 51 is formed in an axisymmetrical shape with respect to the center line 53, and is configured so that when the indicator line 25 of the main body 2 and the center line 53 are aligned, the side surfaces 54a and 54b on both sides of the center overlap the side surfaces 20a and 20b of the main body 2. The pivot shaft 52 is provided at the rear end of the indicator line 25, and both sides of the pivot shaft 52 are provided with trimmed oblique sides 55a and 55b. By providing such oblique sides 55a, 55b, when the putter face Paf is placed on the reference surface 24, the base 5 is prevented from interfering with the putter face Paf, and the main body 2 can rotate smoothly along the putter face Paf.

[0023] 5 shows an embodiment for practicing at an outdoor putting practice area with a lawn. When using the putting practice aid 1 of the present invention on grass, a golf tee 6 is inserted into the grass from above into the shaft hole 28, and the inserted golf tee 6 is used as the pivot axis. The shaft hole 28 as described above is preferably formed at or near the center of gravity of the main body 2. When the shaft hole 28 is located at the pivot axis, the main body 2 rotates smoothly around the pivot axis, making it easier to align the reference surface 24 with the orientation of the putter face Paf of the putter, and the orientation of the putter face Paf can be detected more accurately.

[0024] 6 is an overall perspective view showing another example of the configuration of the putting practice aid 1. In this embodiment of the putting practice aid 1, the main body 2 is made up of a single member, and a housing groove 22s for housing the laser beam oscillator 3 is formed on the upper surface 23b or the lower surface 23a. The rear end of the light transmission groove 23s is connected to the tip side of the housing groove 22s, and the tip of the light transmission groove 23s is connected to the tip portion 20. This configuration makes it possible to reduce the number of parts and simplify the assembly process.

[0025] 7 is an overall exploded perspective view showing another example of the configuration of the putting training aid 1. In this embodiment of the putting training aid 1, the laser beam oscillator 3 is disassembled into a laser oscillator 30a that generates a laser beam, power supplies 32a and 32b that supply power to the laser oscillator 30a, and a switch 31a, and housing units are provided to house each of these components. By disassembling the laser beam oscillator 3 in this way and providing housing units for each component separately in the main body 2, it is possible to reduce the size of the main body 2.

[0026] An accommodation groove 222a for accommodating the laser oscillator 30a is provided on the upper surface 221 of the lower material 22. This accommodation groove 222a is formed with a short axial length in order to accommodate only the laser oscillator 30a, and power supply accommodation grooves 222b and 222c for accommodating batteries 32a and 32b that serve as the power source for the laser oscillator 30a are formed on both sides of the base end of the accommodation groove 222a in parallel to the accommodation groove 222a. In addition, a switch 31a is accommodated between the power supply accommodation grooves 222b and 222c, and the laser oscillator 30a, batteries 32a and 32b, and switch 31a are electrically connected.

[0027] Grooves of the same shape are also formed on the lower surface 211 of the upper member 21 at positions corresponding to the accommodation groove 222a and the power supply accommodation grooves 222b and 222c, and by overlapping the upper member 21 and the lower member 22, these paired grooves form an accommodation section that accommodates the laser oscillator 30a and the batteries 32a and 32b within the main body 2. In addition, a switch hole 26 that accommodates a switch button 27 is formed in the upper member 21 at a position opposite the switch 31a, so that the switch 31a can be operated via the switch button 27. By adopting the above-described configuration, the axial length of the main body 2 formed in the shape of an isosceles triangle can be shortened, thereby achieving miniaturization.

[0028] As shown in Figure 8, the laser irradiation can be configured to display not only the ball's destination but also the trajectory leading up to the destination. Specifically, as shown in the figure, the laser beam oscillator 3 is provided with a function for swinging the laser irradiation direction vertically to cause the laser irradiation to reciprocate. This function can be easily implemented using a known device.

[0029] To obtain the vertical amplitude of the laser, at least the portion of the base material 22 distal to the tip of the laser beam oscillator 3 is cut out along dotted line 227. With this configuration, when a laser is irradiated toward the laser receiving member 4 provided on the edge of the cup C, the laser, which reciprocates vertically, is irradiated in a fan shape centered on the irradiation port 34 of the laser beam oscillator 3, and reciprocates between imaginary lines Lg1 and Lg2 shown in FIG. 8. Because the oscillation range extends below the ground, the laser irradiates not only the laser receiving surface 41 but also the floor surface (ground), and the portion irradiated by the laser is displayed as line Lm. In addition, a movement trajectory 42 of the laser irradiation appears on the laser receiving surface 41 of the laser receiving member 4. Line Lm indicates the trajectory of the ball's roll, and movement trajectory 42 indicates the ball's arrival point.

[0030] In the above-described embodiment, the reference portion is a reference surface, but the reference portion is not limited to a surface. For example, as shown in FIG. 9, the reference portion may be two protrusions 241a, 241b protruding from both ends of the base of an isosceles triangle. By abutting such a pair of protrusions against the putter face Paf, the orientation of the putter face can be detected. The shape of the main body 2 is not limited to a triangle, and is not particularly limited as long as it has an indicator portion indicating the direction, but it is preferable that the shape indicate the direction as a whole. For example, the shape may be an arrow shape, a pentagon, or any other odd-numbered polygonal shape.

[0031] As another variation, as shown in FIG. 10, the indicators do not have to be lines. A pair of triangular protrusions 251a and 251b are provided as markers at the center of the base (reference surface side) of an isosceles triangle. A line M extending from the vertex 20 toward the reference surface 24 is perpendicular to the reference surface 24 and passes through the center point between the pair of markers (protrusions 251a and 251b). A viewpoint Wa is set at a position where the tip 20 can be seen through the gap 251s between the vertices of the pair of protrusions 251a and 251b, and the position of the cup C within the field of view from this viewpoint is confirmed. The extension of the line M connecting the gap 251s and the tip 20 can be predicted as the direction in which the ball will travel. The relationship between the direction of the ball (line M) hit with a determined stance and the actual position of the cup C can be used to determine the extent and direction in which the stance positioning needs to be corrected. Note that instead of a pair of markers, a single marker may be provided on the line M.

[0032] As described above, the putting practice aid 1 of the present invention allows for putting practice using a putter used in competitions. It also has a compact configuration that makes it easy to carry. [Explanation of symbols]
