Description

  The present invention relates to a putting practice instrument that can be used for golf strokes, in particular, to improve the stroke accuracy with which a straight stroke can be accurately performed.

  It is not easy to correct a problem simply by pointing out a bad swing or stroke during a golf lesson. Especially for those who have experienced an ideal swing at all or rarely, such as beginners to average level players, especially if the advanced player wants to correct a collapsed swing. It is quite difficult to point out only at the point.

Utility Model Registration No. 3115975

Therefore, a golf practice machine as described in Patent Document 1 has been proposed. This golf practice machine is installed behind the player with the main bar aligned with the shaft plane, so that the player can visually check their swing path and the difference between the main bar. .
Thus, most of the existing golf practice machines including the above-described check function focus on the swing of the club, and have not heard much of the focus on the putter stroke.

This is because putting is greatly influenced by the actual situation of the golf course green (the way the ball bends and speeds) and does not require strength, so the stroke theory is not as established as the club. The reason is considered.
For this reason, most of the existing putting practice machines were simple, with a hole in a mat that resembles a green.

However, since golf scores are greatly influenced by putting, there should be a full-fledged practice device for putting.
There are two necessary points to acquire the putting technique. That is,
It is how to read the undulating green line and how to hit the head face accurately and accurately on the ball.
The former is basically a rule of thumb, but the latter may be able to be mastered efficiently by using exercise equipment well.
The present invention has been made by paying attention to the above-mentioned conventional problems. It is small and can be easily attached to and detached from an actual putter, and in particular, a force capable of straightly and accurately striking a ball most important in putting. The purpose is to provide a putting practice tool that can be used to improve the performance.

As a result of trial and error, the present inventor has shown a line of laser light perpendicular to the face surface of the putter head, which is the basic of putting, how to make an accurate stroke that rolls the ball far without being bent straight. The present invention was completed by finding that it can be easily confirmed visually by using it as an indicator line that moves together with a stroke.
The invention of claim 1 of the present invention is a putting practice device that can be detachably attached to a golf putter, and is attached to a shaft and projects a laser beam in a line shape toward the head side; and A projection button that is attached to a grip and drives the laser light projection unit to project laser light. When the grip is gripped, the projection button is pressed, and laser light is projected from the laser light projection unit in a line shape. The putting practice instrument is characterized in that a line perpendicular to the face surface of the putter head is drawn on the green.

  The invention according to claim 2 is the putting practice instrument according to claim 1, wherein the laser light is green light.

  According to a third aspect of the present invention, in the putting practice instrument according to the first or second aspect, the laser light projection unit includes a diffractive optical element that converts the laser light into a dot row, and a laser light line is formed on the green. It is a putting practice instrument characterized by being drawn as a dot row.

  According to a fourth aspect of the present invention, in the putting practice instrument according to any one of the first to third aspects, the laser light projection unit is pivotally attached to the shaft, and the rotation position of the laser light is determined by the rotation. This is a putting practice instrument characterized in that the part drawn by the line can be adjusted in the range from the position immediately below the head to the putting destination side by changing.

  According to a fifth aspect of the present invention, in the putting practice instrument according to any one of the first to fourth aspects, the laser light projection unit and the projection button are connected by wire, and the laser light projection unit is respectively connected to both ends of the line. And a projection practice instrument characterized in that the projection button is arranged.

According to the putting practice instrument of the present invention, since it is small and can be detachably attached to an actual putter, it can be taken to a golf course and used on an actual green.
In addition, the putting practice device of the present invention projects a line perpendicular to the face surface of the putter head as light, and when the player swings, the line light moves along with the stroke. Whether the laser beam line is traced can be confirmed from the irradiation state of the laser beam line. Therefore, the direction of the stroke in putting can be easily confirmed visually.

In response, the laser drive circuit 11 is driven to emit laser light from the laser light source 13. This laser light is adjusted to line-shaped light, that is, line light, via the condensing / line conversion lens system 15 and then incident on the diffractive optical element 17. The diffractive optical element 17 has a diffraction pattern on the incident surface, and incident laser light is converted into a dot row by the diffractive action of the diffraction pattern. The size of each dot corresponds to the beam size of the incident laser beam.

Reference numeral 19 denotes a holder. The holder 19 has a split portion on the front side and is open in the vertical direction. When the housing 5 is inserted into the holder 19 from above, the lower part of the housing 5 is held and held from the side, and the step 7 of the housing 5 comes into contact with the upper surface of the holder 19 so that it falls off. Is blocked.
On the back side of the holder 19, a clamp 21 having an embedding surface in an arc shape is fixed. When the clamp 21 is elastically expanded to widen the lateral gap, the putter shaft can be inserted from the side, so that the shaft can be clamped in a horizontal state without passing through the shaft.
The holder 19 is connected to a clamp 21 via a ball bearing, and can rotate.

A projection button 23 is provided as a trigger for the laser light projection unit 3 having the above-described configuration.
The main body of the projection button 23 is a vertically-long rectangular plate-like switch piece 25 to which a switch board (not shown) is attached. A tape attachment portion 27 is provided near the lower side of the switch piece 25. The upper part of the tape attachment part 27 extends on both the left and right sides to form extension parts 29 and 29. Further, between the extended portions 29, 29, a bulged portion 31 is bulged in an arc shape on the surface side.
Reference numeral 33 denotes a hook-and-loop fastener tape, and one end of the hook-and-loop fastener tape 33 is passed through and fixed to the tape attachment portion 27.
In addition, on the surface side of the switch piece 25, a red light emitting display lamp 35 for indicating that laser projection is being performed is arranged.

Reference numeral 37 denotes a code, and the lead wire is folded in two in the code 37. One end of the cord 37 enters the housing 5 of the laser light projection unit 3, and the exposed lead wire is connected to the laser driving circuit 11. The other end is connected to the switch board of the projection button 23 by wire connection. Further, the lighting circuit for the display lamp 35 is interposed on the projection button 23 side.
With this circuit configuration, when the switch piece 25 of the projection button 23 is pressed, the circuit is closed and the laser driving circuit 11 is driven. Further, when the button is pressed, the above-described display lamp is turned on.

  The putting practice instrument 1 is configured as described above, and the laser light projection unit 3 and the projection button 23 are connected by a cord 37. When not in use, the cord 37 is folded. It can be made compact and easy to carry.

FIG. 2 shows a state in which the putting practice instrument 1 is mounted on an actual putter P.
On the laser light projection unit 3 side, the clamp 21 is attached to the shaft S of the putter P while the housing 5 is held by the holder 19.
In a state where the shaft S is upright, the housing 5 is held by the holder 19 so as not to fall off, and the light exit window faces downward. Since the laser light is in a line shape and is projected downward from the light emission window, the line L is substantially perpendicular to the face surface of the head H.

On the projection button 23 side, the hook-and-loop tape 33 is wound around the grip G of the putter P while the hook-and-loop fastener tape 33 is pressed against the grip G of the putter P. ing.
Since the extended portions 29 and 29 and the bulging portion 31 are hung on the upper edge of the surface fastener tape 33 that has been wound and has come to the front side, the switch piece 25 does not fall off from the surface fastener tape 33. Further, since the length of the hook-and-loop fastener tape 33 and the length of the cord 37 are set with a margin, it is possible to bring the switch piece 25 to a position where the player can easily push the switch piece 25 in accordance with how the player holds it.

The putting practice instrument 1 is used by being attached to the putter P as described above, and the laser light is projected toward the green on the ground side.
The projected laser beam becomes a line-shaped dot row and illuminates the green.
As shown in FIG. 2, the laser beam (L) is a line of dot rows having a certain length across the head H.

Using the putter P to which the putting practice instrument 1 is attached, practice as shown in FIG.
That is, when putting in the actual green and assuming that there is a virtual ball (B) beside the head H of the putter P, the putting swing is performed.
Since the laser light is projected toward the green, a line (one-dot chain line) orthogonal to the face surface of the putter head moves along with the stroke and is drawn on the green. The player can confirm from the irradiation state of the laser beam line whether the laser beam line traces the line in the direction of rolling the ball.

  Therefore, if the line in the direction of rolling the ball and the line of the laser beam are misaligned, the player repeatedly shakes the putter P while checking the irradiation state of the line light, so that the player can change the putting direction. It can be corrected.

FIG. 4 shows a state in which the laser light shines on the green.
The case where the laser beam is set to red and green and further formed into a simple line shape is compared with the case where it is formed into a dot row.
As shown in this figure, the green color is easier to see than the red color, but it is much easier to see due to the dot arrangement.
Since the putting practice instrument 1 according to the above embodiment is of a green type and irradiates in a dot row shape, the line is the easiest to see.

Since lasers are radiation, safety standards are set strictly internationally. For this reason, the output of many laser devices is set, making it difficult to see outdoors during the day.
On the other hand, the putting practice instrument 1 of the present invention uses green which is easy to see, and further makes it easy to see in the form of a dot array. It has become.
In addition, the laser beam is emitted only when the grip G is gripped, and the shaft does not turn extremely sideways in putting, so the laser beam is not directed to the surrounding people and is safe. Sex is also secured.

In the putting practice instrument 1, the holder 19 of the laser beam projection unit 3 is rotatable with respect to the clamp 21, so that the laser beam line can be adjusted by adjusting the rotation angle as shown in FIG. You can bring it forward.
If you become an advanced person, you need to be able to stroke straight and accurately even on the far side away from the head H, but according to the putting practice instrument of the present invention, you can change the position of the laser light line, so beginners It can correspond to the technical level from the advanced to the advanced.

FIG. 6 shows another example of the laser light projection unit 41.
The housing 43 is integrally provided with a holder function. That is, the sphere 45 is attached to the back side of the housing 43. Moreover, the housing | casing 43 is a single 5 battery utilization type.
Since the spherical body portion 45 is externally fitted to the bearing portion 49 having the concave portion on the clamp 47 side, when the holding portion 51 of the clamp 47 is fixed by holding the shaft S of the putter P, the housing 43 side becomes the shaft S. By rotating with respect to the angle, the angle can be changed.

By the way, depending on the irradiation location, there are cases where it is easier to see laser irradiation in red or laser irradiation in a continuous line rather than a dot row.
Corresponding to such a case, prepare a plurality of laser modules according to the type of laser light, leave the housing attached with an attachment, and install the laser module you want to use to the housing each time It is also possible.

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, the width and interval of lines drawn by laser light irradiation, and the total length can be set as appropriate.
