Description

  The present invention relates to a bunker shot practice tool capable of effectively practicing a bunker shot in which a ball hit into a bunker is launched from the bunker.

  In golf play, if a player is driven into a bunker, high skill is required for launching from the bunker, and the quality of the score is greatly affected by the skill of the bunker shot. Since bunker shots are important, various bunker shot practice tools for improving the accuracy of bunker shots have been proposed as shown below.

  FIG. 13 is a diagram showing a configuration example of a bunker shot practice tool described in Japanese Patent Laid-Open No. 07-328169 in the prior art. The bunker shot practice tool described in Japanese Patent Application Laid-Open No. 07-328169 is provided with a bunker and a side groove-like slope body inclined at the tip thereof, and a ball catcher for stopping the speed of the ball is attached to the upper end of the slope body, A golf ball placed in a bunker can be regarded as a golf ball driven into a bunker, and bunker shots can be practiced, and both the launched golf ball and sand are arranged so as to return to the bunker without flying outside the device. (Patent document 1).

  FIG. 14 is a diagram showing a configuration of a bunker shot practice tool described in Japanese Patent Laid-Open No. 2012-165768 in the prior art. The bunker shot practice tool described in Japanese Patent Application Laid-Open No. 2012-165768 is attached to a golf ball. The wing-like swing guide piece 12 is attached to the golf ball, and the attachment direction and angle of the wing-like swing guide piece 12 are attached. Therefore, the golf club head has a function of easily recognizing the impact of the golf ball by visually recognizing the incident angle and the track direction of the head of the golf club (Patent Document 1).

JP 07-328169 A JP 2012-165768 A

According to the bunker shot practice tool described in Patent Document 1, it can be practiced easily by installing it on the yard of a home or the rooftop of a company.
However, it was simply a simple reproduction of a bunker, and in that reproduced bunker, a golf ball was deferred and practiced by just striking it. For this reason, users are not able to receive tips on how to hit bunker shots, but if they only wear their own habits, it is not a practice. It is thought that there are many.

According to the bunker shot practice tool described in Patent Document 2, by attaching the wing-shaped swing guide piece 12 to the golf ball, the incident angle and the trajectory direction of the golf club head can be visually determined by the mounting direction and the mounting angle. This makes it possible to recognize the impact of a golf ball easily. However, there are problems with this bunker shot practice tool. Since the wing-like swing guide piece 12 is directly attached to the golf ball and is maintained in the obliquely upward direction, the user can imagine the incident angle and the track direction as the swing guide piece 12 is. And hit the golf ball just before it.
As described above, in the conventional bunker shot practice tool, the user has not always been able to easily grasp the tips for bunker shot.

  In addition, since the bunker shot practice tool described in Patent Document 2 is attached by attaching the wing-shaped swing guide piece 12 to the golf ball, it is difficult to adjust the angle of the golf ball manually. However, it is difficult to show the correct incident angle and track direction of the head of the golf club.

Further, since the bunker shot practice tool described in Patent Document 2 is attached by attaching the wing-shaped swing guide piece 12 to the golf ball, it fails during practice and the golf ball or the swing guide piece 12 is directly hit by the club head. In many cases, the swing guide piece 12 may be bonded and the swing guide piece 12 may come off.
Thus, there is a difficulty in using the bunker shot practice tool of Patent Document 1 and the bunker shot practice tool of Patent Document 2.

The inventor Okumoto Sono, the inventor of the present invention, has been focusing on golf guidance for many years and has been focusing on the fact that there are so many trainees who suffer from bunker shots while teaching trainees as golf coaches. I have been studying how to make trainees learn the tips of bunker shots efficiently in a short period of time. Among them, players who are not good at bunker shots have noticed that when they make a bunker shot, they often misunderstood that the club does not touch the sand and must hit the ball directly.
Actually, instead of directly hitting the golf ball when making a bunker shot, swing the club to an ideal position determined from the ball, for example, a position about 3 to 4 cm away from the golf ball. It is necessary to instruct them to fly with the sand. Originally, many golfers tend to think of so-called duffing or topping as a miss shot. However, if it is impossible to understand that it is a trick to make a `` golf shot with the golf ball and the sand in front of it '' that seems to be a miss shot at first glance, the escape of the ball entering the bunker is It seems almost impossible. In addition, in the bunker shot, the head at the time of impact is inserted, the incident angle that falls, the opening and closing of the face, the size of the swing, the height and distance of the ball depending on the force, the spin amount It is necessary to learn through practicing bunker shots.

  Therefore, when the bunker shot is made for the trainee, the club is not directly applied to the ball, but the club is moved to a hitting point slightly away from the ball, for example, 3-4 cm away from the ball. The incident angle comes down and the size of the swing, the size of the swing, and the force are used to instruct the ball and the sand in front of it to be thrown away, recalling a practice tool that makes it easy for anyone to learn the tips of a bunker shot. It came to do.

  The present invention has been made in view of various problems caused by the above-described conventional bunker shot training tool, and an object thereof is to provide a bunker shot training tool that makes it easy to learn the tips of a bunker shot. To do.

In order to achieve the above object, the bunker shot practice tool of the present invention includes a plate face body placed on a bunker, a ball installation portion for placing a golf ball provided on the plate face body, and the plate face body on the plate face body. An impact position guide that is formed at a predetermined distance from the ball setting portion and serves as a mark indicating the impact position when the club head is swung down in a bunker shot, and a mark indicating the impact angle when the club head is swung down in the bunker shot It is equipped with an impact angle guide.
The impact angle guide may be configured to be indicated by a line or a graphic printed on the plate face body or a cut edge in the plate face body.

  With the above configuration, when using the bunker shot practice tool of the present invention, the position where the club head should be swung down in a bunker shot, i.e., a predetermined distance from the golf ball, just by swinging down the club head while aiming at the impact position guide. It can be accurately guided to the position, and trainees can easily learn the tips for bunker shots.

Also, since the impact angle guide looks flat from the perspective of the trainee, it may seem that the angle guide function is insufficient when swinging down the club. However, since the plank body of the bunker shot practice tool of the present invention can be seen diagonally forward when viewed from the position where the trainee holds the club, in fact, the trainee can clearly understand the angle at which the head should be swung down. It has become. That is, if the club head is swung down along the apparent line of the impact angle guide, it is the incident angle of the head when the club head is swung down.
In addition, regarding the swinging down of the head, information indicating strength instructions (strong, somewhat strong, slightly weak, weak etc. instructions, numbers that are indicators of strength such as 1 to 5) are displayed on the plate. Show it.
Similarly, on the plate body, it is possible to print at least various information necessary for the bunker shot, such as the approach direction, the trajectory of the golf ball, and the holding direction.

Next, the plate face will be described.
The basic shape may be a substantially disk shape. This is because it is easy to handle if it is substantially circular, and its shape is compact and convenient for storage.
Further, if the plate body is circular, there is an advantage that since the golf club has a uniform shape with no corners or cuts, the impact is easily dispersed everywhere the golf club hits, and there is little risk of breakage or damage of the plate body.
Note that the plate face does not necessarily have a substantially disc shape. For example, the plate body may be a non-circular shape, and the shape thereof may be a shape that makes it easy to grasp the extending direction of a line connecting the ball installation portion from the impact position guide. With such a shape, it is possible to easily grasp the direction in which the golf ball should fly when practicing bunker shots. For example, the bunker shot may be practiced in the green direction.
The material of the plate body is not particularly limited. As an example, the plate face body can be formed of a flexible plastic sheet material or a cardboard material.
In addition, it is also preferable to form the plate body from a transparent material. This is because when placed on a bunker, the bunker can be seen through, so that the bunker can be conscious, and even when practicing bunker shots, a feeling close to that of an actual battle can be obtained.

  Next, a configuration in which holes or notches for air venting or sand venting are provided in the plate face body is also possible. Thus, by providing the hole or notch in the plate face body, the hole or notch becomes a kind of air vent or sand vent, and the bunker shot practice tool of the present invention is launched by the impact of the golf club. The flight distance can be suppressed. Although the golf ball is spherical and has a kind of streamline, since the bunker shot practice tool of the present invention is flat, it easily receives the momentum of sand that pops out due to the striking force of the golf club and flies like a golf ball. . Therefore, by providing a hole or a notch for a type of air vent or sand vent, the bunker shot practice tool is devised so as not to fly excessively.

Next, a configuration in which a notch opening from the impact position guide to the ball setting portion is provided in the plate face body is also possible.
By providing the notch opening, there is an effect that the structure is reduced from the position where the club head is swung down to the golf ball, and the practice of impacting the bunker can be performed in a situation close to an actual bunker shot. In other words, there is no structure between the driving position of the club head and the golf ball, and the visual sensation is close to the sensation of an actual bunker shot as if the golf ball existed in the bunker. It is done.

  According to the bunker shot practice tool of the present invention, just by aiming and swinging down the impact position guide, it can be accurately guided to a position a predetermined distance from the golf ball to be swung down as a bunker shot. You will be able to easily learn the tips. In addition, regarding the angle to be swung down as a bunker shot, if you swing down along the impact angle guide as it follows the direction of the line of the impact angle guide, you can practice a bunker shot that impacts at an accurate angle. Moreover, regarding the strength to which the head is swung down, if the instruction information indicating the strength of the impact shown on the plate is used as a clue, it is possible to practice a bunker shot that impacts with an appropriate strength.

  Hereinafter, embodiments of the bunker shot practice tool of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to the specific application, shape, number, etc. shown in the following examples.

A configuration example of the bunker shot practice tool 100 of the present invention shown in the first embodiment will be described.
FIG. 1 is a diagram illustrating the bunker shot practice tool 100 according to the first embodiment.
The bunker shot practice tool 100 includes a ball setting unit 110, an impact position guide 120, an impact angle guide 130, and a plate face 150. In this configuration example, a print 160 including various information necessary for practicing bunker shots is further provided on the plate body 150.
FIG. 2 shows a usage example of the bunker shot practice tool 100 according to the first embodiment, and also shows a golf ball 200.

First, each structure of the bunker shot practice tool 100 of this invention is demonstrated.
The plate body 150 is a plate body placed on a bunker. The plate body 150 is a structure that supports the entire bunker shot practice tool 100 of the present invention, and is preferably a flat plate so as not to obstruct the practice of the bunker shot.
In this configuration example, it is substantially on a disc, but shapes other than the substantially disc are possible as shown in Example 2 and Example 3 described later.

The material of the plate body 150 will be described. The plate body 150 is preferably provided with a structural strength that is difficult to break and torn, since the club head may collide during bunker shot practice. For example, it is assumed that it is formed of a plastic sheet material. Some plastic sheet materials are hard and easy to break, but here they are soft and strong in tensile strength, such as vinyl material, polypropylene (PP) material, polyethylene (PE) material, polyethylene terephthalate (PET) material. Those that are difficult to tear are preferred.
In addition, it is also preferable to form the plate body 150 from a flexible material. Since the bunker is recessed, it has a flat part and a curved part. Since it can be sufficiently assumed that the golf ball is hit on the curved surface portion of the bunker, it is necessary to practice the bunker shot assuming the curved surface portion of the bunker. In that case, it is preferable to bend so that the plate body 150 may follow the curved surface part of a bunker. Therefore, if the plate body 150 is formed of a flexible material, the plate body 150 can be deformed along the curved surface of the surface of the bunker on which the bunker shot practice tool 100 of the present invention is placed.

  It is also preferable to form the plate body 150 from a transparent material. In actual bunker shots, golf balls hit directly on the bunker's sand are shot only with the impact shots of the golf club, so the sense of the underlying sand is more similar to the actual bunker shot. May be obtained. Therefore, if the plate body 150 is formed of a transparent material, when the trainee practice bunker shot using the bunker shot practice tool 100 of the present invention, the ground sand ground can be seen through the plate body 150. There is a possibility that a feeling close to a bunker shot can be obtained.

The ball installation unit 110 is a portion on which a golf ball provided on the plate surface 150 is placed. In this configuration example, the ball installation unit 110 is an opening opened in the center of the plate surface 150 and has a circular frame. The size of the golf ball is slightly larger than the diameter of the golf ball and fits within the frame.
FIG. 2 is a diagram showing a state in which the bunker shot practice tool 100 of the present invention is used. As shown in FIG. 2A, when using the bunker shot practice tool 100 of the present invention, the golf ball 200 is placed on the ball installation unit 110 and installed.
In addition, the ball installation part 110 is slightly larger than the diameter of the golf ball 200, and the lie state in the bunker can be adjusted. FIG. 2B reproduces a normal lie state in which the golf ball 200 is placed on the surface of the bunker. FIG. 2 (c) reproduces the lie state in which the golf ball 200 is slightly buried in the sand of a bunker. FIG. 2D reproduces the state of the lie in which the golf ball 200 is in a so-called “eyeball state” in which the golf ball 200 is deeply buried in the sand of the bunker. As shown in FIGS. 2B to 2D, the trainee can reproduce the state of the lie of the golf ball to be practiced by adjusting the degree of pushing the golf ball 200 into the sand.

  The impact position guide 120 is disposed at a position on the bunker a predetermined distance before the golf ball provided on a part of the plate face 150, and indicates the position to swing the club head down in the bunker shot. It is a mark of the position to swing down. In this configuration example, the mark is provided at the edge of the plate face 150, and the difference between the diameter D2 of the plate face 150 and the diameter D1 of the ball setting portion 110 is approximately the distance L that the impact position guide 120 should secure. . The distance L of the impact position guide is a distance that should be separated from the golf ball 200 in an ideal bunker shot. One of the tips for bunker shots is not to swing down the golf ball 200 and swing down the club head in front of the distance L. By using this impact position guide 120, the golf ball 200 Positions separated by the distance L can be easily grasped.

  The impact angle guide 130 indicates the angle to which the club head swings down in the impact position guide 120, and is, for example, a line or a graphic printed on the plate face 150. In the configuration example of FIG. 1, it is shown as diagonal lines drawn on a circular disk. The angle indicated by the oblique lines indicates the angle at which the club head is swung down. The usage and effects of the impact angle guide 130 will be described later.

  The swing guide 140 guides the locus of the swing of a golf club head such as a sand wedge. With this swing guide 140, the trainee can easily grasp that it is sufficient to approach the head of the sand wedge toward the impact position 120 along the direction indicated by the swing guide 140, and the impact has occurred at the impact position 120. Thereafter, it can be understood that it is sufficient to follow through the head of the sand wedge along the direction indicated by the swing guide 140.

  Thus, by combining the three pieces of information of the impact position guide 120, the impact angle guide 130, and the swing guide 140, it becomes possible for the trainee to easily grasp basic information necessary for practicing bunker shots.

  In the configuration example shown in FIG. 1, printing 160 (number of 160 is not shown) including various information necessary for practicing bunker shots is further applied on the plate body 150. . In this example, information such as approach direction 161, stance 162, eye line 163, and locus 164 of the golf ball is printed. These pieces of information are collectively referred to as printing 160. These prints may vary depending on the type of bunker shot.

  The approach direction 161 indicates the direction in which the golf ball flies. The bunker shot practice tool 100 of the present invention may be placed on the bunker so that the green is in this direction. In this example, it is an arrow mark.

The stance 162 indicates the direction in which the body is turned, the angle of the foot, how to apply the weight, and the like. In this example, it is a footprint. In this example, the number “6” is drawn on the left footprint, and the number “4” is drawn on the right footprint. This is the ratio of the weight applied to the left and right feet. This is a simple illustration and means that you should hang your weight on your left foot. (This is because the club head tends to enter an acute angle in the case of left foot weight.)
A line of sight 163 indicates a direction in which the face is directed. In this example, it means that the face should be set to face the golf ball according to the position.

  The golf ball trajectory 164 is obtained by swinging the club face down to the position indicated by the impact position guide 120 at the angle indicated by the impact angle guide 130 according to the position specified by the print 160 information, etc. It is a simple indication of how high and how far to fly. In this example, a parabola as shown in the locus 164 of the golf ball is drawn to reach the green.

A method of using the bunker shot practice tool 100 of the present invention having the above basic configuration will be described.
FIG. 3 simply shows the correction effect of a bunker shot using the bunker shot practice tool 100 of the present invention. The bunker shot practice tool 100 and the golf ball 200 of the present invention are actually viewed from the trainee's perspective. It shows how it was seen.
When trainees practice bunker shots, when the golf ball 200 and the bunker shot practice tool 100 of the present invention are placed on the bunker and held at an appropriate standing position, as shown in FIG. The bunker shot practice tool 100 of the invention will be seen obliquely forward. As shown in FIG. 3, the trainee can easily grasp the information regarding the points to be aware of in the bunker shot.

  First, the swing trajectory of the head of the sand wedge can be easily grasped sensuously by the swing guide 140. It can be easily grasped sensuously that the sand wedge should be swung down toward the impact position along the direction indicated by the swing guide 140, and after the impact, the sand wedge is aligned along the direction indicated by the swing guide 140. It is easy to understand sensuously what should be done by following through. Here, it can be grasped that the sand wedge should be swung in a slightly oblique direction instead of the approach direction 161 which is the direction of the green in which the golf ball is to fly.

Further, the impact position guide 120 allows the position of the sand wedge head to be swung down to easily grasp the position to be impacted. Here, it can be understood that the sand wedge should be swung down to a position slightly apart from the position just below the golf ball 200.
Next, the impact angle guide 130 makes it possible to easily and intuitively grasp the angle of the sand wedge head at the moment of impact. Here, it can be understood that the impact should be made with a slight angle on the sand wedge face, instead of impacting at right angles to the approach direction 161.

  Thus, by combining the three pieces of information of the impact position guide 120, the impact angle guide 130, and the swing guide 140, it becomes possible for the trainee to easily grasp basic information necessary for practicing bunker shots.

Further, in this configuration example, it is possible to grasp what should be known in the bunker shot by the printing 160 on the plate body 150.
First, the approach direction 161 makes it easy to sensuously sense in which direction the green is.
Next, with the stance 162, the direction in which the body is turned, the angle of the foot, how to apply weight, etc. can be easily grasped sensuously.
Next, the direction of the face and the like can be easily perceived by the eyes 163.
Next, the golf ball trajectory 164 is used to perform a bunker shot that satisfies these various conditions, and the golf ball hits at what height and what distance the golf ball draws. The trajectory can be easily grasped sensuously.

  As for the strength of impact by swinging down the club head, it is also possible to present information serving as an indication of the strength as a print 160 to the trainee. For example, it is possible to indicate “strong”, “slightly strong”, “slightly light”, or “lightly” as the strength of impact. This “adjustment of power” varies from individual to individual, and should be learned through practice.

  By using the bunker shot practice tool 100 of the present invention described above, the trainee can easily learn the tips for bunker shots.

As the bunker shot practice tool 100a according to the second embodiment, an impact angle guide 130a having a configuration example indicated by a cut edge in the plate face 150a is shown.
FIG. 4 is a diagram illustrating the bunker shot practice tool 100a according to the second embodiment. Here, the description of the same components as those of the bunker shot practice tool 100 shown in FIG. 1 according to the first embodiment will be omitted, and the description will focus on differences from the first embodiment.
As shown in FIG. 4, the bunker shot practice tool 100a includes a ball setting part 110a, an impact position guide 120a, an impact angle guide 130a, a swing guide 140a, and a plate face body 150a.

  In this configuration example, the impact angle guide 130a is a cut edge in the plate face body 150a. The impact angle guide 130 shown in the first embodiment is a diagonal line printed on the board surface of the plate face 150, but in this configuration example, as shown in FIG. Is easier to see.

The method of using the bunker shot practice tool 100a according to the second embodiment is the same as that shown in FIG. FIG. 5 simply shows the correction effect of a bunker shot using the bunker shot practice tool 100a according to the second embodiment of the present invention. From the perspective of the trainee, the bunker shot practice tool 100a according to the present invention is actually shown. Further, a state where the golf ball 200 is seen is shown.
When trainees practice bunker shots, when the golf ball 200 and the bunker shot practice tool 100a of the present invention are placed on the bunker and set in an appropriate standing position, as shown in FIG. The bunker shot practice tool 100a of the invention will be seen obliquely forward. As shown in FIG. 5, the trainee can easily grasp the information regarding the points to be careful in the bunker shot.

  The swing guide 140a shown in FIG. 5 is the same as the swing guide 140 shown in FIG. 3, and the swing trajectory of the head of the sand wedge can be easily grasped sensuously. Further, the impact position guide 120a shown in FIG. 5 is the same as the impact position guide 120 shown in FIG. 3, and the position to be impacted by swinging down the head of the sand wedge can be easily grasped sensuously. Here, the impact angle guide 130a shown in FIG. 5 has a cut edge of the outline, which is different from the impact angle guide 130 of FIG. 3 which is a printed diagonal line. It is the same, and the angle of the head of the sand wedge at the moment of impact can be easily grasped sensuously.

  As described above, according to the bunker shot practice tool 100a according to the second embodiment, the trainee student can combine the three pieces of information of the impact position guide 120a, the impact angle guide 130a, and the swing guide 140a, and various pieces of information of the printing 160. Therefore, the basic information necessary for practicing bunker shots can be easily grasped.

As a bunker shot practice tool 100b according to Example 3, a configuration example in which holes 151b for air venting or sand venting are provided on the plate body 150b is shown.
FIG. 6 is a diagram illustrating the bunker shot practice tool 100b according to the third embodiment. Here, the description of the same components as those of the bunker shot practice tool 100 shown in FIG. 1 according to the first embodiment will be omitted, and the description will focus on differences from the first embodiment.

As shown in FIG. 6, the bunker shot practice tool 100b includes a ball setting part 110b, an impact position guide 120b, an impact angle guide 130b, a swing guide 140b, and a plate face 150b.
In this configuration example, as shown in FIG. 6, the plate face body 150b is provided with holes 151b for air venting or sand venting. The number and shape of the air vent or sand vent holes 151b are not particularly limited, but in this configuration example, four air vent or sand vent holes 151b are provided as circular holes.

  By providing the hole 151b in the plate body 150b, the hole 151b can be a kind of air vent or sand vent. In the bunker shot, since the impact point of the golf club impacts in front of the golf ball 200 and hits the golf ball 200 with sand, the golf club face does not actually impact the golf ball 200 directly. The golf ball 200 flies by the pressure obtained from the sand that is in contact with the ball. Here, although the golf ball 200 has a spherical shape and a kind of streamline, the bunker shot practice tool 100b of the present invention is flat, so that it is easy to receive the momentum of sand popping out by the striking force of the golf club. Similarly, it jumps out in the launch direction. Therefore, by providing a hole 151b that serves as a type of air vent or sand vent, sand and air from the lower side of the plate face 150b of the bunker shot practice tool 100b are appropriately removed. The effect that the shot practice tool 100b does not fly excessively is obtained.

The example of a structure which provided the notch opening part from an impact position guide to a ball | bowl installation part with respect to a plate body as a bunker shot practice tool concerning Example 4. FIG.
FIG. 7 is a diagram illustrating the bunker shot practice tool 100c according to the fourth embodiment. Here, the description of the same components as those of the bunker shot practice tool 100 shown in FIG. 1 according to the first embodiment will be omitted, and the description will focus on differences from the first embodiment.

As shown in FIG. 7, the bunker shot practice tool 100c includes a ball setting part 110c, an impact position guide 120c, an impact angle guide 130c, a swing guide 140c, and a plate face body 150c.
In this configuration example, as shown in FIG. 7, the plate face 150c is provided with a notch opening 152c from the impact position guide 120c to the ball setting portion 110c.
Further, in this configuration example, the impact position guide 120c is provided at two points on the outermost periphery of the edge of the notch opening 152c, and the integrated region connecting them can be grasped as a place to be impacted. Yes.
In this configuration example, the impact angle guide 130c is a diagonal line printed on the board surface of the plate body 150c, and the trainee can clearly recognize the angle at which the club head is swung down. ing.

  By providing a notch opening 152c in the plate face 150c, there is a bunker shot guide by the bunker shot practice tool 100c, but there is no structure between the position where the club head is swung down and the golf ball 200, There is an effect that the sense of visual observation is close to that of an actual bunker shot as if the golf ball 200 is present in the bunker.

  In the bunker shot, since the impact point of the golf club impacts in front of the golf ball 200 and hits the golf ball 200 with sand, the golf club face does not actually impact the golf ball 200 directly. The golf ball 200 flies by the pressure obtained from the sand that is in contact with the ball. Here, by providing the notch opening 152c, there is no structure between the head of the sand wedge and it is possible to practice bunker shots while obtaining a feeling close to that of an actual bunker shot.

As bunker shot practice tools concerning Example 5, the example of composition of various other patterns in which the external shape of a plate face object other than circular is shown.
Here, the description of the same components as those of the bunker shot practice tool 100 shown in FIG. 1 according to the first embodiment will be omitted, and the description will focus on differences from the first embodiment.

FIG. 8 is a diagram illustrating the bunker shot practice tool 100d according to the fifth embodiment.
FIG. 9 is a diagram illustrating another shape of the bunker shot practice tool 100e according to the fifth embodiment.
FIG. 10 is a diagram illustrating a bunker shot practice tool 100f of still another shape according to the fifth embodiment.

  The bunker shot practice tools 100d, 100e, and 100f are similar to the first embodiment, respectively, the ball setting portions 110d, 110e, and 110f, the impact position guides 120d, 120e, and 120f, the impact angle guides 130d, 130e, and 130f, and the swing guides 140d and 140e. 140f and plate surface bodies 150d, 150e, and 150f, as shown in FIG. 8, in this configuration example, the outer shapes of the plate surface bodies 150d, 150e, and 150f are non-circular.

  For example, in the case of the bunker shot practice tool 100d, the whole is generally arrow-shaped, and it is clearly easy to understand that the apex direction of the arrow is the direction in which the golf ball is launched. Further, in the case of the bunker shot practice tool 100e, the whole is roughly an arrow shape, and it is clearly easy to understand that the apex direction of the arrow shape is the direction in which the golf ball is launched. Further, in the case of the bunker shot practice tool 100f, the whole is generally a so-called keyhole shape, and it is sensuously easy that the straight portion of the keyhole shape points to the approach direction 161f, which is the direction in which the golf ball is launched. It can be grasped.

As Example 6, the bunker shot practice tool 100 (Type, Btype, Ctype) according to Example 1 having three patterns in which the flying distance and height of the bunker shot are changed is shown.
FIG. 11A shows a bunker shot practice tool 100 of A type (a type having a relatively large flight distance and a relatively low flight height), and FIG. 11B shows a B type (having a flight distance). The bunker shot practice tool 100 is shown as having a relatively medium flight height. FIG. 12 shows a bunker shot practice tool 100 of C type (having a relatively small flight distance and a relatively high flight height).
As described above, it will be understood that various types of bunker shots can be practiced by arranging several types of bunker shot practice tools 100 of different types.

  While preferred embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made without departing from the scope of the invention. Therefore, the technical scope of the present invention is limited only by the description of the appended claims.
