Description

[Technical Field]

[0001] The present invention relates to a putter training machine used for practicing golf, and more particularly to a putter training machine used for practicing putting. [Background technology]

[0002] An example of this type of conventional technology is the golf putting training tool described in Patent Document 1. The golf putting training tool described in Patent Document 1 has two guide plates arranged in parallel and a plate whose both ends are pivotally connected to the two guide plates, and is configured so that the space between the two guide plates can be closed or opened.

[0003] When practicing, the two guide plates are spread apart and placed on the grass, and swings are repeated between the two guide plates so that the putter head does not come into contact with the two guide plates, allowing the user to correct their swing.When storing, the putter can be made compact by closing the gap between the two guide plates. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3245801 Summary of the Invention [Problem to be solved by the invention]

[0005] As a result of various verification studies, the inventors discovered that the rolling behavior of a ball varies depending on the vertical position of the putter head at the time of impact between the ball and the putter head. The golf putting training device described in Patent Document 1 allows practice to correct swing direction. However, when putting, the trainee views the ball from above, making it difficult to determine the vertical position of the putter head. Therefore, there is a need for a golf putting training device that can determine the vertical position of the putter head, so that the user can determine the height of the putter head from the ground at which the putter head should be struck to achieve a good rolling behavior.

[0006] The present invention has been made to solve the above-mentioned problems in the prior art, and aims to provide a putting practice machine that has the function of being able to determine the up and down position of the putter head when hitting the ball. [Means for solving the problem]

[0007] The putter training machine of the present invention has the following configuration.

[0008] The putter training machine of the present invention is a base to be placed under the user's feet; a height check unit disposed on the base and configured to measure the height of the putter head when the user swings the putter and hits the ball; the base has a placement portion that indicates a position where the ball is placed; The height check unit a support shaft attached to the base and extending in the vertical direction; a plurality of flat plate members each having one end rotatably supported by the support shaft; The plurality of flat plate bodies are each pivotally supported by the support shaft so as to be independently rotatable, The other ends of the plurality of flat plates are arranged at positions that allow them to come into contact with the putter head when the putter head hits the ball placed on the placement section.

[0009] According to the present invention configured as described above, when the putter head impacts the ball, the plate that contacts the putter head rotates, while the plate that does not contact the putter head remains. By checking the remaining plate, it is possible to determine the vertical position of the putter head when it hits the ball.

[0010] The putter training machine of the present invention also includes: The putter further includes a guide portion attached to the base at a position opposite to the height check portion, the guide portion serving as a guide for the movement direction of the putter when a user swings the putter, The guide portion is a connecting shaft that hinge-connects one end of the first flat plate extending in the longitudinal direction to one end of the second flat plate, the second flat plate is in sliding contact with the putter when the user swings the putter, The plate is rotatable relative to the first plate and is held in a rotated position.

[0011] According to the present invention configured in this way, by aligning the heel of the putter head with the second plate forming the slope, stable and highly reproducible practice becomes possible. Moreover, since the angle of the second plate can be freely changed, it is possible to set the angle of the second plate to a pulling style that suits oneself (the degree to which it is pulled on an inside trajectory). In this way, it is possible to customize a stroke that is easy to swing and practice it repeatedly.

[0012] The putter training machine of the present invention also includes: The golf club further includes a follow-through indicator attached to the tip end of the base, the follow-through indicator being used by a user to indicate the magnitude of the follow-through after impact. The follow-through indicator portion is a rail portion slidably held on the base and protruding from a tip of the base; The follow-through indicator plate is rotatably supported at the tip end of the rail portion and is displaceable between a reclined position and an upright position relative to the rail portion.

[0013] According to the present invention configured in this way, the follow-through indicator plate is positioned on the follow-through side when the user swings the putter, and is configured so that if the follow-through is too great, the putter head will come into contact with the follow-through indicator plate and fall over. This allows the user to follow through toward the follow-through indicator plate and stop the putter head so that it does not hit the follow-through indicator plate, allowing them to practice controlling and correcting the magnitude of their follow-through. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a putting practice machine having a function that makes it possible to determine the up and down position of the putter head when the putter head hits the ball. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention will be described in more detail below using preferred embodiments, but the following embodiments are merely examples of realizing the present invention and the present invention is not limited thereto.

[0017] The configuration of a putting practice machine 1 according to one embodiment of the present invention will be described.

[0018] Figures 1, 2 and 3 are perspective views showing the appearance of a putter training machine 1 in one embodiment of the present invention, where Figure 1 is a view seen from above on one side, Figure 2 is a view seen from above on the other side, and Figure 3 is a view seen from below on one side.

[0019] [Putter Practice Machine 1] The putter training machine 1 is configured to include a long base 2 placed under the user's feet so as to extend in the direction in which the user swings the putter, and a guide section 3, a follow-through indicator section 4, and a height check section 5 attached to the base 2.

[0020] 3, the base 2 is made of metal and includes a first base portion 21, a second base portion 22, a first connecting portion 23, and a second connecting portion 24. The base 2 can be configured in any shape, such as a plate-like body, as long as it can fix at least the height check unit 5.

[0021] The first base portion 21 is an elongated member that extends in the direction in which the user swings the putter (the front-to-back direction shown in FIG. 1 ) and has a substantially C-shaped cross section. A rail plate 42 of the follow-through indicator portion 4, which will be described later, is inserted into the first base portion 21. In addition, the first base portion 21 is formed with engagement portions 21a, on both the front and back sides, that engage (for example, screw) with the tip end of a fixing member (for example, a screw) 35a of the guide portion 3, which will be described later.

[0022] Returning to Figure 1, the second base portion 22 is disposed parallel to the first base portion at a predetermined distance that is longer than the width of the putter head. The second base portion 22 is an elongated member that extends in the direction in which the user swings the putter (the front-to-back direction shown in Figure 1) and has a substantially C-shaped cross section. A rail plate 43 of the follow-through indicator portion 4, which will be described later, is inserted into the second base portion 22.

[0023] The length of the second base portion 22 in the longitudinal direction is longer than 40 cm (for example, 50 cm), and a scale of 0 to 40 cm is marked on the surface. Furthermore, flat extension portions 22a are formed on one side of the second base portion 22 extending in the longitudinal direction on the outer side, extending outward from the scale positions indicating 0 cm, 10 cm, 20 cm, 30 cm, and 40 cm. A through-hole is formed in the center of this extension portion 22a. The tip of the second base portion 22 has an area where no scale is marked, and a through-hole 22b is formed in the surface of this area.

[0024] The first connecting portion 23 consists of a flat plate-like member that connects the tip of the first base portion 21 and the tip of the second base portion 22, and has a U-shaped mounting portion 23a in the center on which a ball is placed, and horizontal portions 23b that extend outward from both ends of the U-shaped mounting portion 23a.

[0025] Placement portion 23a has an open portion 23d consisting of a circular hole in the center that serves as an index for where to place the ball, and a notch that widens in a V shape from this circular hole toward the tip side.

[0026] An end of one horizontal portion 23b is fixed to the back surface of the tip of the first base portion 21, i.e., the back surface of the area on either side of the scale indicating 0 cm where no scale is displayed. The end of the other horizontal portion 23b is fixed to the back surface of the tip of the second base portion 22, i.e., the back surface of the area on either side of the scale indicating 0 cm where no scale is displayed.

[0027] The second connecting portion 24 is a rectangular flat plate-like member that connects the rear end portions of the first base portion 21 and the second base portion 22. The horizontal portion 23b of the first connecting portion 23 and the second connecting portion 24 are parallel to each other.

[0028] The guide portion 3 has a first flat plate 31 that is substantially rectangular and long, a second flat plate 32 that has substantially the same shape as the first flat plate 31, and a connecting shaft 33 that hinge-connects the first flat plate 31 and the second flat plate 32.

[0029] The first flat plate 31 has a cylindrical bent portion on one side extending in the longitudinal direction excluding both ends, and the second flat plate 32 has a cylindrical bent portion on both ends of one side extending in the longitudinal direction.

[0030] When one side of the first flat plate 31, on which the cylindrical bent portion is formed, and one side of the second flat plate 32 are aligned, a single cylinder is formed by the cylindrical bent portions of the first flat plate 31 and the second flat plate 32, and by passing the connecting shaft 33 through this cylinder, the first flat plate 31 and the second flat plate 32 are hingedly connected to each other so that they can be opened and closed freely. Because a frictional force acts between the side surface of the connecting shaft 33 and the inner surface of the cylinder, when the first flat plate 31 and the second flat plate 32 are opened, they are maintained in that state.

[0031] The length of the first flat plate 31 in the longitudinal direction is longer than 50 cm (for example, 60 cm), and scales from 0 to 50 cm are marked on the surface of the first flat plate 31. Furthermore, on one longitudinal side of the first flat plate 31 that is not hinged, flat extension portions 31a are formed that extend outward from the scales indicating 10 cm, 20 cm, 30 cm, 40 cm, and 50 cm, and a through-hole is formed in the center of each extension portion 31a. Furthermore, there are areas on both ends of the first flat plate 31 where no scales are marked. Slots extending in the width direction of the first flat plate 31 are formed to the right of the 0 cm scale and to the left of the 40 cm scale on the first flat plate 31, and cylindrical in / out adjustment portions 35 are formed to surround these slots.

[0032] Figure 4 is a diagram illustrating the guide unit 3 of the putter training machine 1 in one embodiment of the present invention. Figure 4(a) shows the guide unit 3 separated from the second base unit 22, Figure 4(b) shows the guide unit 3 moved closer to the second base unit 22, and Figure 4(c) shows the guide unit 3 with the leading end moved closer to the second base unit 22 and the trailing end moved away from the second base unit 22.

[0033] The entry / exit adjustment parts 35 are formed at positions (two positions in the example shown in FIG. 2) corresponding to the engagement parts 21a of the first base part 21 when the guide part 3 is placed on the first base part 21. The guide part 3 is fixed onto the first base part 21 by inserting fixing members (for example, screws or the like) 35a into the elongated holes of the entry / exit adjustment parts 35 and engaging with the engagement parts 21a of the first base part 21.

[0034] With this configuration, when the fixing members 35a, whose tip ends engage with the engaging portions 21a of the first base portion 21 in the two in / out adjustment portions 35, are fixed at a position (upper in FIG. 4) closer to the second base portion 22 (see FIG. 2), the guide portion 3 is fixed to the first base portion 21 in a state spaced apart from the second base portion 22, as shown in FIG. 4(a). In the example shown in FIG. 4(a), the guide portion 3 is fixed in a state parallel to the second base portion 22.

[0035] Furthermore, when the fixing members 35a of the two in / out adjustment parts 35, whose tip sides engage with the engaging parts 21a of the first base part 21, are fixed at a position (lower in FIG. 4) away from the second base part 22 (see FIG. 2), the guide part 3 is fixed to the first base part 21 in a state where it is close to the second base part 22, as shown in FIG. 4(b). In the example shown in FIG. 4(b), the guide part 3 is fixed in a state where it is parallel to the second base part 22.

[0036] In addition, when the fixing member 35a, whose tip side engages with the engaging portion 21a of the first base portion 21, is fixed at a position (lower in FIG. 4) away from the second base portion 22 (see FIG. 2) at one (e.g., the front side) of the two in / out adjustment portions 35, and the fixing member 35a, whose tip side engages with the engaging portion 21a of the first base portion 21, is fixed at a position (upper in FIG. 4) closer to the second base portion 22 at the other (e.g., the rear side) of the two in / out adjustment portions 35, the guide portion 3 is fixed to the first base portion 21 with the tip side closer to the second base portion 22 and the rear end side of the guide portion 3 away from the second base portion 22, as shown in FIG. 4(c). In the example shown in FIG. 4(c), the guide portion 3 is fixed in a state where it is disposed obliquely with respect to the second base portion 22.

[0037] Returning to FIG. 2, when the guide portion 3 is disposed parallel to the second base portion 22, when the guide portion 3 and the second base portion 22 are viewed in plan from above, an imaginary line connecting the scale indicating 0 mm displayed on the guide portion 3 and the scale indicating 0 mm displayed on the second base portion 22 is perpendicular to the longitudinal direction of the guide portion 3 and the second base portion 22. Furthermore, this imaginary line is positioned rearward of the center of the circular hole in the open portion 23d by the radius of the ball. In other words, the scale indicating 0 mm displayed on the guide portion 3 and the second base portion 22 corresponds to the impact position between the ball and the putter head.

[0038] The follow-through indicator portion 4 includes a follow-through indicator plate 41, rail plates 42 and 43, and a rotation shaft 44.

[0039] The follow-through indicator plate 41 is made of a generally rectangular flat plate member whose width is the length from the outer side surface of rail plate 42 to the outer side surface of rail plate 43 and is longer than the diameter of the ball. An arch-shaped hole 41a is formed in the lower center of the follow-through indicator plate 41, allowing the ball to pass through. Both ends of the lower end of the follow-through indicator plate 41 are formed into a cylindrical shape.

[0040] The rail plate 42 is made of a long, rectangular plate-like member that can be inserted into the first base portion 21.

[0041] The rail plate 43 is made of a long, rectangular plate-like member that can be inserted into the second base portion 22. The length of the rail plate 43 is approximately 50 cm, and a scale is marked on the surface of the rail plate 43. This scale indicates the length from the scale indicating 0 cm on the first base portion 21 to the follow-through indicator plate 41. Specifically, when the scale indicating 5 cm on the rail plate 43 is positioned at the tip of the second base portion 22, it indicates that the length from the scale indicating 0 cm on the first base portion 21 to the follow-through indicator plate 41 is 5 cm. When the rail plate 43 is inserted into the second base portion 22, the scale becomes visible through the through-hole 22b.

[0042] A bearing portion is formed at the tip of the rail plates 42, 43. This bearing portion is composed of a plate-shaped extension piece extending upward from the tip of one side extending in the longitudinal direction of the rail plates 42, 43, and a through hole formed in the center of this extension piece. By inserting a rotary shaft 44 into the through hole of this bearing portion and the cylindrical portion at the lower end of the follow-through indicator plate 41, the follow-through indicator plate 41 is rotatably attached to the tip end of the rail plates 42, 43. The follow-through indicator plate 41 rotates toward the front end, and when rotated toward the rear end, the follow-through indicator plate 41 is restricted so as not to rotate more than 90 degrees relative to the rail plates 42 and 43. In other words, when the follow-through indicator plate 41 is rotated toward the rear end, it is in an upright position.

[0043] As shown in FIG. 2, the height checking unit 5 includes a plurality of check bars 51, an extension piece 52, and a support shaft 53.

[0044] The multiple check bars 51 are rod-like flat plates that notify the user of the height from the ground. The extension piece 52 is made of a flat plate-like member and is fixed to a position slightly toward the tip of the scale indicating 0 mm on the inner back surface of the second base portion 22. The support shaft 53 is erected on the extension piece 52 and extends in the vertical direction.

[0045] FIG. 5 is a plan view showing the configuration of check bar 51 of putter training machine 1 in one embodiment of the present invention. The check bar 51 has a flat plate-shaped main body 51a that is shorter than the horizontal portion 23b, and a circular hole 51b that is formed at one end of the main body 51a in the longitudinal direction and through which the support shaft 53 is inserted.

[0046] Numbers indicating the height from the ground are displayed on the surface of the main body 51a. According to this embodiment, the thickness of the main body 51a is 1 mm. Furthermore, because the surface of the extension piece 52 is set to be 2 mm above the ground, the support shaft 53 supports the first check bar 51 at a height of 3 mm above the ground. The first check bar 51 is marked with a "3." According to this embodiment, the height check unit 5 is formed by stacking the check bars 51 marked with "3" to "15" on the support shaft 53 in numerical order. Each check bar 51 is supported by the support shaft 53 so as to be independently rotatable. It is desirable that the check bars 51 have a slippery surface so that the friction generated between two check bars 51 in contact with each other is minimized. This reduces the possibility of multiple check bars 51 rotating together. Furthermore, the check bars 51 may be configured to be detachable from the support shaft 53.

[0047] [Example of using the putter practice machine 1] Next, an example of how to use the putter training machine 1 according to this embodiment will be described. When using the putting practice machine 1, first, the follow-through indicator plate 41 is rotated and set up on the tip of the rail plates 42, 43, and then the first base portion 21 and the second base portion 22 are placed on the grass surface.

[0048] Next, the user pulls out the rails 42 and 43 to position the follow-through indicator 41 at the desired location. The follow-through indicator 41 is used when practicing a shot that stops the putter head during the follow-through (so-called "snatching"). It is positioned at the desired location for the putter head to stop. For example, an analysis of the putting of USPGA Tour players reveals that short putts stop exactly 5 to 10 cm after impact. Even slightly longer putts of about 5 meters stop exactly 15 to 20 cm after impact. Therefore, when practicing short putts, the follow-through indicator 41 is positioned approximately 15 cm from the impact position, and when practicing longer putts, the follow-through indicator 41 is positioned approximately 25 cm from the impact position.

[0049] Next, the user lifts the second flat plate 32 and rotates it to a desired angle. The surface of the second flat plate 32 forms a slope that slopes downward toward the second base portion 22 side. The second flat plate 32 is used for stroke practice. By placing the heel of the putter head against the tilted second flat plate 32 and making strokes along the surface of the second flat plate 32, the assistance of the second flat plate 32 makes it possible to repeatedly practice similar strokes, thereby enabling the player to acquire strokes with high reproducibility.

[0050] Specifically, the greater the tilt of the second plate 32, the greater the degree of inward pull. In other words, the ability to freely adjust the angle of the slanted plate means that the putter head can be adjusted to a degree of inward pull that suits the individual. For example, if the angle is set to 90 degrees, the putter head will be pulled completely straight, and in reality, this trajectory cannot be achieved unless the putter head is tilted forward enough to make the spine parallel to the ground. Furthermore, tilting the second plate 32 to about 60 degrees allows for a slight inward pull, which is typical of many conventional stances. Furthermore, tilting the second plate 32 to 45 degrees allows for a pull that emphasizes the inward pull. In this way, the user can adjust the pull (degree of inward pull) that suits them and practice repeatedly.

[0051] Next, the user adjusts the orientation of the tips of the multiple check bars 51 so that the multiple check bars 51 are perpendicular to the longitudinal direction of the second base portion 22. As a result, the tips of the check bars 51 are positioned so that they can come into contact with the putter head when the putter head hits the ball placed on the placement portion 23a.

[0052] In order to check the size of the putter's backswing, a thread-like member may be stretched between the extension portion 31 a and the extension portion 22 a. For example, if the takeback is to be 20 cm, pins may be inserted into the through-holes of the extension portion 31 a and the extension portion 22 a that correspond to the scale indicating 20 cm, and ends of the thread-like member may be attached to the pins, thereby stretching the thread-like member on the rear surfaces of the first base portion 21 and the second base portion 22.

[0053] During practice, the user holds the putter, places a ball on the placement portion 23a, and then stands to the side of the guide portion 3. At this time, the guide portion 3 and the second base portion 22 are placed under the user's feet so that they extend in the direction in which the user swings the putter, and the follow-through indicator plate 41 is placed on the follow-through side.

[0054] Fig. 6 is a plan view schematically showing the operation of check bar 51. Fig. 7 is a side view schematically showing the operation of check bar 51. The user places the putter head between the first base portion 21 and the second base portion 22 and faces the ball as shown in Figures 6(a) and 7(a). Then, the user takes a backswing, swings the putter back toward the rear end, and then hits the putter head against the ball on the mounting portion 23a. This causes the ball to roll and pass through the hole 41a.

[0055] When the putter head hits the ball, as shown in Figures 6(b) and 7(b), the upper check bar 51 that hits the putter head rotates, and the number displayed on the top check bar 51 of the remaining lower check bars 51 corresponds to the height from the ground. This allows the user to know the height of the putter head when hitting the ball by visually checking this number. For example, when the putter head passes 5 mm above the ground, the check bars 51 that are 5 mm or higher are brushed away, and the check bars 51 that are 5 mm or lower (check bars 51 with the number 5 written on them) remain, so it is easy to tell that the putter head hit the ball at a height of 5 to 6 mm.

[0056] The inventors have verified that many professional golfers hit the ball with the putter head about 5 to 10 mm above the ground when putting. Furthermore, in an experiment using a putting robot, they have verified that the ball rolls better when the ball impacts with the putter head about 9 mm above the ground. Therefore, according to this embodiment, by repeatedly practicing so that the check bar 51 with the number 9 written on it remains and the check bar 51 with the number 10 or above rotates, the probability of reproducing a stroke in which the putter head impacts with the putter head about 9 mm above the ground increases.

[0057] Furthermore, the user stops the putter head in the follow-through after hitting the ball. If the putter head comes into contact with the follow-through indicator plate 41 and the follow-through indicator plate 41 falls in the follow-through direction, the user can determine that the stop was not successful.

[0058] [Action and effect] According to the embodiment of the present invention configured as described above, the following advantageous effects are achieved.

[0059] According to this embodiment, the height check unit 5 is provided, and upon impact between the putter head and the ball, the check bar 51 that comes into contact with the putter head rotates, while the check bar 51 that does not come into contact with the putter head remains without rotating. By checking the numerical display of the remaining check bar 51, the user can check how many millimeters the putter head was lifted when making a stroke. Based on the check results, the user can get a reference for how the ball will roll depending on how many millimeters the putter head is lifted when hitting the ball, and can find the putter head height that is best suited to their putter.

[0060] Furthermore, according to this embodiment, by aligning the heel of the putter head along the second flat plate 32 that forms the slope, stable and highly reproducible practice becomes possible. Moreover, since the angle of the second flat plate 32 can be changed as desired, it is possible to set the angle of the second flat plate 32 to a pulling style that suits oneself (the degree to which the putter is pulled on an inside trajectory). In this way, it is possible to customize a stroke that is easy to swing and match it to one's own stroke, and practice it repeatedly.

[0061] Furthermore, according to this embodiment, the follow-through indicator plate 41 is provided, and by stopping the putter head during the follow-through so as not to hit the follow-through indicator plate 41, practice can be performed to control and correct the magnitude of the follow-through. Furthermore, the first flat plate 31 and the second base portion 22 of the guide portion 3 are formed with extension portions 31a and 22a at regular intervals, and by placing an indicator, such as a thread-like member stretched between the extension portions 31a and 22a, it is possible to check the magnitude of the putter's take-back. This allows practice to control and correct the magnitude of the take-back. As such, according to this embodiment, practice can be performed to control and correct both the magnitude of the take-back and the magnitude of the follow-through.

[0062] Furthermore, since the putter training machine 1 in this embodiment is mainly composed of plate-shaped and rod-shaped members, it can be disassembled to make it compact enough to fit in a golf bag.

[0063] Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments. For example, according to the above-described embodiments, the height check unit 5 is provided on the second base portion 22, but it goes without saying that the height check unit 5 may be provided on the first base portion 21. Furthermore, the height check unit 5 may be provided on both the first base portion 21 and the second base portion 22.

[0064] The extension piece 52 may also be detachable from the second base portion 22, allowing the height check unit 5 to be used alone. In this case, two height check units 5 may be used, one on the toe side and one on the heel side of the putter, and used like gates. In this case, it is also possible to measure the difference in the lift of the toe and heel.

[0065] A hole into which a tee can be inserted is provided near the support shaft 53 in the second base portion 22 and towards the tip, and by inserting a tee into this hole, if the check bar 51 rotates significantly, the check bar 51 comes into contact with the tee standing in the through hole 22b, restricting further rotation. This prevents the check bar 51 from rotating once and coming to rest on top of the remaining check bar 51 without rotating, making it difficult to check the numbers on the remaining check bar 51.

[0066] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. [Explanation of symbols]
