Description

  Golf is a sport that can be enjoyed in lush and spacious nature. Considering the origin of golf, golf that can be played with a single club is called snack golf (also known as stick golf), and the golf ball is made large, light and soft to reduce the flight distance and make it easier to hit, according to the rules of golf It is accepted as a golf introductory sport that can be played, as a family sport and a lifelong sport, and aims to increase the golf population and expand the use of the golf course. The club head and shaft shape and structure and the new hole shape and structure are changed so that only one club can be used by exchanging the head part of the club used for snack golf and extending and shortening the shaft length. It is.

Conventional golf clubs are composed of drivers 1-5, irons 1-9, pitching wedges, sand wedges, putters, etc., and many clubs are used. Each club has a fixed loft angle of the head and a length of the shaft, and the head and the shaft have an integral structure.
It is stipulated that any 14 clubs can be used.

In the case of golf, since the ball is small, skill is required to hit the core, and since the “bending” (elasticity) of the shaft is used to extend the flight distance, it is a sport that requires advanced technology.
A club is selected for each shot according to the target distance and course conditions. For this reason, we have a lot of clubs such as several drivers, several irons, sand wedges, putters, etc., so it is bulky and heavy overall, and we use caddies and carts to carry around to concentrate on playing, sports I feel a little uncomfortable as an image. In addition, the purchase price is high and the image of high-class sports is strong, and there is a sense of distance as a familiar sport.
For this reason, in snack golf, the sweet spot is expanded by enlarging the ball, and by making it light and soft, the flight distance is reduced and it is easy to hit, and play can be performed according to the rules of golf. Since the combination of head part replacement and shaft length expansion / contraction can be set by himself, an address suitable for the hitting situation can be obtained, and only one club is required.

In order to respond to the distance of the course and the situation of the hitting point, the devised club uses four different types of drivers, irons, sand wedges and putters with different loft angles, so it can be used around fairways, bunker and green You can use them properly and enjoy playing without destroying the image of golf.
In addition, by combining the expansion and contraction of the shaft length, it is possible to make an address corresponding to the situation of the distance and the ball hitting point, and in the same way as selecting a conventional golf club, the club according to the course situation The club shape and structure have been devised so that you can set your own.

Playing a tee shot, approaching, and playing with a putt is golf itself, and you can easily learn the basics of golf. The point is that the ball is large, light, soft, no club “bending”, and the club length can be adjusted.
1. Like golf clubs, the head has a putter, driver, iron, and sand wedge, and you can set the loft angle, lie angle, and shaft length to suit you.
2. The club has four types of heads to be exchanged, so you can understand the basics of selecting a club according to the course situation, distance, and hitting situation.
3. By placing the sole of the head on the ground, the loft angle can be realized, and the length of the club can be adjusted according to the situation of the hitting point, and the address can be grasped.
4). The club has no “bending”, so it is learned that the flight distance can be extended by taking the basic form of hitting the ball core.
5. By making the ball larger than the golf ball (diameter 56-58 mm), the sweet spot becomes larger, and it becomes lighter and softer, making it easier to hit by making the weight less than or equal to the golf ball. I feel that it can be done easily because the size of the ball is intermediate between golf and baseball, tennis, etc., and I can play away the existing concept.
6). By changing the weight of the ball used according to age and skill, golfers who have become beginners or elderly people can enjoy golf without difficulty in their physical strength and visual acuity.
7). Just like golf and other sports, you can hit it as hard as you like, and it's a play in a vast greenery where you can enjoy a sense of fulfillment.
8). There are various types of balls for urethane sports and children's playground equipment with strong repulsive force. The size and weight are specified for snack golf, and the structure should be as diverse as the golf ball.
9. You can use the rules of golf as they are, so you can learn how to understand and understand the points of play and think about solutions.
10. Snack golf equipment is one club, the number of heads is four, the capacity is small, light weight, so you can carry it by yourself from children to the elderly, so you can learn the way of the original sport.
11. Since the flight distance is suppressed and the number of hits is increased, the course can be 9 holes (half), thereby reducing the play time, play cost, and expenses.
12 In the green nature, it can be a fun sport that can be easily played by beginners, and it can also be a family sport and a lifelong sport at a low cost.
13. Being a promising candidate for family sports and lifelong sports leads to an increase in the golf population and the expansion of golf course users, thereby improving golf course management.
14 By changing the incident angle of the shaft, the lie angle suitable for the loft angle can be set, and addressing can be performed with the loft angle and lie angle suitable for the situation of the hitting point.
15. Since the shaft has a constant thickness, the telescopic structure is not required by changing the grip position, and simplification can be achieved by eliminating the tip replacement structure exclusively for golf.
16. By replacing the gear with a different insertion gear with the rotational position of the gear shifted, it becomes the same as having eight heads.

1. Head shape and structure Snack golf considers the origin of golf, and there is only one club. As an easy golf that can be enjoyed in a spacious green golf course, the golf ball is made large, light and soft to reduce the flight distance. This is a golf introductory sport that makes it easy to tackle, so it is possible to carry it by yourself without relying on caddies and carts, and consider the shape and structure of the club that can handle each scene with a single club.
However, clubs with different loft angles that can respond to changing course distances and hitting points are still necessary, and as a coping method, in baseball, it is possible to handle from off-site home runs to bunts with a single bat. In the case of golf, there should be at least four clubs with different loft angles, currently used drivers, irons, sand wedges, and putters.
As a countermeasure, there is only one club shaft, changing the loft angle by changing the head part. You can change the loft angle by rotating one head without changing the head.
Four types of heads (1) Driver with emphasis on flying distance (Loft angle 15 °)
▲ 2 Iron with emphasis on reliable direction (loft angle 30 °)
(3) Sand wedge with an emphasis on launching from sand (loft angle 50 °)
(4) Putter with a focus on accurate rolling on the green (Loft angle 0 °)
[FIG. 7] As shown in FIG. 8, the head and the shaft are separated, the shaft tip is bent at an average lie angle of 60 °, and a square shaft insertion hole is provided on the back of the head to provide a square shaft tip. Insert and fix the part, and the head striking surface is given an angle that is the average loft angle of each of the four types of heads.
The center height of the shaft is close to the radius of the ball to prevent the head from wobbling and to increase the flight distance.
As shown in [Fig. 1], the driver is for increasing the flight distance, and the head is thickened to create a mass-like shape and structure, and by using a shape that is sensuously similar to a golf club, Eliminate the sense of discomfort.
The putter has a large lie angle. Therefore, as shown in [FIG. 4], an angle of 15 degrees is perpendicularly formed in the shaft insertion hole on the back surface of the head, and the lie angle of the average putter becomes 75 degrees when inserted. Also, the iron can be angled at 5 degrees, the lie angle can be 65 degrees, the sand wedge can be angled at 10 degrees, and the lie angle can be 70 degrees to make it easier to hit the body.
The material of each head is made of a material and thickness that can sufficiently cope with the impact at the time of impact.
2. Loft angle conversion structure-1
In golf, when selecting a club, a club having a loft angle that seems to be optimal for the situation of the ground contact point of the ball and the target distance is selected.
In Snack Golf, there are four types of heads, and each loft angle is based on a general average value of 15 degrees for a driver, 30 degrees for an iron, 50 degrees for a sand wedge, and 0 degrees for a putter. The lie angle is obtained by bending the front end portion of the club at an average lie angle of 60 degrees, and it can sufficiently cope with the situation by expanding and contracting the shaft length and making the head sole a large curve.
As described above, it is possible to select and set the head in consideration of one's own striking force, and to make an address corresponding to the target distance and situation. While baseball and tennis hit a fast changing ball with one bat and one racket, snack golf hits a lighter, softer ball than a golf ball stationary on the ground. By combining the selection of the type of head and the expansion and contraction of the club length, an address corresponding to the situation can be obtained.
Also, the lie angle can be accommodated by making the sole part of the head a large curve, and the sweet pot does not come off because the ball is large.
3. Securing the bottom of the head (sole) and level feeling When selecting a golf club and hitting it, the club is placed on the ground many times and the address is confirmed and hit. At this time, the sole of the head is placed on the ground and the angle difference between the ground surface and the horizontal is grasped. Basically, a satisfactory address cannot be obtained unless the sense of level is grasped. In order to eliminate this concern, a shape / structure that can maintain the level of the head bottom plate in accordance with the loft angle is required, and the direction and distance of hitting the ball with the head of the selected club can be assumed. All four types of snack golf club heads have a shape and structure that can secure the selected loft angle as shown in [Fig. 5] by grounding the sole horizontally, so that you can get a sense of the loft angle when hitting. Can do.
4). Loft angle conversion structure-2
As shown in [FIG. 10], as shown in FIG. 10, the tip end portion has a gear-like meshing structure, the club tip is separated into a shaft and a head, and the two cross sections are meshed to form a gear shape. . The loft angle is changed by inserting the head into the shaft and shifting it one by one. By making 360 degrees into a 24 gear structure, it is possible to change the angle by 15 degrees by shifting the meshing of the gears by one.
Therefore, four types of loft angles can be used from the head shape: putter (loft angle 0 degrees), driver (loft angle 15 degrees), iron (loft angle 30 degrees), and sand wedge (loft angle 45 degrees). The bolt cross section is tightened and fixed with a nut, and a loft angle conversion structure that prevents the head from popping out is obtained.
The sand wedge usually has a large loft angle of 56 degrees, but with a gear structure it is 45 degrees, but the ball is large, and the sole part of the head is a large curve, so it can be hit close to the body by expanding and contracting the shaft length. It responds by the same feeling that the lie angle changes correspondingly. Since the putter usually has a loft angle of 0 degrees and a lie angle of 75 degrees, if the lie angle is considered insufficient, a putter head shown in FIG. 4 may be prepared separately.
In this way, the loft angle is converted by 15 degrees by shifting the meshing of the gear structure. Since the club is simplified and the ball is large, light and soft, it is satisfactory if there are two types of heads: a gear-structured head and a putter head for golf golf. In addition, if a gear shaft structure with a slightly rotated gear position at the tip of the club shaft is prepared separately, one head can be used for eight loft angles, and eight clubs are provided. It will be the same.
As shown in [Fig. 10-3], a hinge with a spring is installed on the bottom surface of the head, as shown in [Fig. 10-3]. By sandwiching a horizontal securing plate corresponding to each loft angle of 6), a loft angle to be selected with respect to the horizontal plane can be obtained, so that a sense can be grasped.
5. Stretch structure of shaft length In golf, there is a difference of about 30 cm in the maximum shaft length between the driver and the putter.
However, stick golf is regarded as an introductory golf, and if the driver can expand and contract by about 20 cm by reducing the length, it can cope with it. For this reason, a 20 cm expansion / contraction target is required for a single club.
As shown in FIG. 6, the shape and structure for expanding and contracting is a double structure at the upper grip portion of the shaft, and is expanded and contracted by sliding up and down by rotation. And, in order to prevent the shaft from coming out at the time of impact and to strengthen the integration of the double structure, a screw type double structure as shown in [Fig. 6-2], which can expand and contract by 1 cm per rotation. It is easy to handle by using a screw thread. Then, a vertical cut is made in the lower part of the covering side, and the cut portion is fastened with a fastener to prevent the shaft from coming out and to ensure the integration of the double structure.
6). Shaft tip conversion structure (lie angle 60 degrees)
As shown in [FIG. 7] and [FIG. 8], the tip portion of the shaft may be replaced with a bolt and nut so that the head portion with an average lie angle of 60 degrees can be removed. The lie angle is basically 60 degrees for all of the driver, iron, sand wedge, and putter, and the putter is angled 15 degrees on the shaft insertion hole on the back of the head as shown in [Fig. 4-2]. Set to 75 degrees.
Note that the driver, iron, and sand wedge can be changed to a lie angle suitable for the club when the head shaft insertion hole is angled in the same manner as the putter.
Further, by providing an angle in the horizontal direction, it is possible to cope with prevention of slice balls and hook balls.
The tip can be replaced with a tip with a different lie angle according to the preference of each person, and when used as a stake, it can be replaced with a tip for a cane.
7). New hole shape and structure As the size of snack golf balls increases, the diameter of the holes will also increase.
In the case of sharing with golf, the shape / structure may be set such that a hole is dug in the size of a snack golf hole as shown in FIG. 8 and a frame that is the size of a conventional golf hole is set.
In addition, as shown in [Fig. 8], with a structure with a circular spring with a spring, and a structure that does not go out once inside, it is placed on the ground without digging holes. What is necessary is just to fix a position with a pin as a shape and a structure.

In the case of golf, there should be at least four clubs with different loft angles, currently used drivers, irons, sand wedges, and putters.
As a countermeasure, there is only one club shaft, changing the loft angle by changing the head part. You can change the loft angle by rotating one head without changing the head.
Four types of heads (1) Driver with emphasis on flying distance (loft angle 15 °)
▲ 2 Iron with emphasis on reliable direction (loft angle 30 °)
(3) Sand wedge with an emphasis on launching from sand (loft angle 50 °)
(4) Putter with a focus on accurate rolling on the green (Loft angle 0 °)
[FIG. 7] As shown in FIG. 8, the head and the shaft are separated, the shaft tip is bent at an average lie angle of 60 °, and a square shaft insertion hole is provided on the back of the head to provide a square shaft tip. Insert and fix the part, and the head striking surface is given an angle that is the average loft angle of each of the four types of heads.
The center height of the shaft is close to the radius of the ball to prevent the head from wobbling and to increase the flight distance.
As shown in [Fig. 1], the driver is for increasing the flight distance, and the head is thickened to create a mass-like shape and structure, and by using a shape that is sensuously similar to a golf club, Eliminate the sense of discomfort.
The putter has a large lie angle. Therefore, as shown in [FIG. 4], an angle of 15 degrees is perpendicularly formed in the shaft insertion hole on the back surface of the head, and the lie angle of the average putter becomes 75 degrees when inserted. Also, the iron can be angled at 5 degrees, the lie angle can be 65 degrees, the sand wedge can be angled at 10 degrees, and the lie angle can be 70 degrees to make it easier to hit the body.
The material of each head is made of a material and thickness that can sufficiently cope with the impact at the time of impact.
2. Loft angle conversion structure-1
In golf, when selecting a club, a club having a loft angle that seems to be optimal for the situation of the ground contact point of the ball and the target distance is selected.
In Snack Golf, there are four types of heads, and each loft angle is based on a general average value of 15 degrees for a driver, 30 degrees for an iron, 50 degrees for a sand wedge, and 0 degrees for a putter. The lie angle is obtained by bending the front end portion of the club at an average lie angle of 60 degrees, and it can sufficiently cope with the situation by expanding and contracting the shaft length and making the head sole a large curve.
As described above, it is possible to select and set the head in consideration of one's own striking force, and to make an address corresponding to the target distance and situation. While baseball and tennis hit a fast changing ball with one bat and one racket, snack golf hits a lighter, softer ball than a golf ball stationary on the ground. By combining the selection of the type of head and the expansion and contraction of the club length, an address corresponding to the situation can be obtained.
Also, the lie angle can be accommodated by making the sole part of the head a large curve, and the sweet pot does not come off because the ball is large.
3. Securing the bottom of the head (sole) and level feeling When selecting a golf club and hitting it, the club is placed on the ground many times and the address is confirmed and hit. At this time, the sole of the head is placed on the ground and the angle difference between the ground surface and the horizontal is grasped. Basically, a satisfactory address cannot be obtained unless the sense of level is grasped. In order to eliminate this concern, a shape / structure that can maintain the level of the head bottom plate in accordance with the loft angle is required, and the direction and distance of hitting the ball with the head of the selected club can be assumed. All four types of snack golf club heads have a shape and structure that can secure the selected loft angle as shown in [Fig. 5] by grounding the sole horizontally, so that you can get a sense of the loft angle when hitting. Can do.
4). Loft angle conversion structure-2
As shown in [FIG. 10], as shown in FIG. 10, the tip end portion has a gear-like meshing structure, the club tip is separated into a shaft and a head, and the two cross sections are meshed to form a gear shape. . The loft angle is changed by inserting the head into the shaft and shifting it one by one. By making 360 degrees into a 24 gear structure, it is possible to change the angle by 15 degrees by shifting the meshing of the gears by one.
Therefore, four types of loft angles can be used from the head shape: putter (loft angle 0 degrees), driver (loft angle 15 degrees), iron (loft angle 30 degrees), and sand wedge (loft angle 45 degrees). The bolt cross section is tightened and fixed with a nut, and the loft angle conversion structure prevents the head from popping out.
The sand wedge usually has a large loft angle of 56 degrees, but with a gear structure it is 45 degrees, but the ball is large, and the sole part of the head is a large curve, so it can be hit close to the body by expanding and contracting the shaft length. It responds by the same feeling that the lie angle changes correspondingly. Since the putter usually has a loft angle of 0 degrees and a lie angle of 75 degrees, if the lie angle is considered insufficient, a putter head shown in FIG. 4 may be prepared separately.
In this way, the loft angle is converted by 15 degrees by shifting the meshing of the gear structure. Since the club is simplified and the ball is large, light and soft, it is satisfactory if there are two types of heads: a gear-structured head and a putter head for golf golf. In addition, if a gear shaft structure with a slightly rotated gear position at the tip of the club shaft is prepared separately, one head can be used for eight loft angles, and eight clubs are provided. It will be the same.
As shown in [Fig. 10] (3), a hinge with a spring is installed on the bottom surface of the head to secure the sense of loft angle and the bottom of the head (sole) and horizontal sensation. By sandwiching the horizontal securing plate corresponding to each loft angle of (6), the loft angle to be selected with respect to the horizontal plane can be obtained, so that the sense can be grasped.
5. Stretch structure of shaft length In golf, there is a difference of about 30 cm in the maximum shaft length between the driver and the putter. However, stick golf is regarded as an introductory golf, and if the driver can expand and contract by about 20 cm by reducing the length, it can cope with it. For this reason, a 20 cm expansion / contraction target is required for a single club.
As shown in FIG. 6, the shape and structure for expanding and contracting is a double structure at the upper grip portion of the shaft, and is expanded and contracted by sliding up and down by rotation. In order to prevent the shaft from coming out at the time of impact and to strengthen the integration of the double structure, a screw-type double structure as shown in FIG. 6 (2), which can expand and contract by 1 cm per rotation. It makes it easy to handle by using a screw thread. Then, a vertical cut is made in the lower part of the covering side, and the cut portion is fastened with a fastener to prevent the shaft from coming out and to ensure the integration of the double structure.
6). Shaft tip conversion structure (lie angle 60 degrees)
As shown in [FIG. 7] and [FIG. 8], the tip portion of the shaft may be replaced with a bolt and nut so that the head portion with an average lie angle of 60 degrees can be removed. The lie angle is basically 60 degrees for all of the driver, iron, sand wedge and putter, and the putter is angled 15 degrees to the shaft insertion hole on the back of the head as shown in [Fig. 4] (2). Is set to 75 degrees.
Note that the driver, iron, and sand wedge can be changed to a lie angle suitable for the club when the head shaft insertion hole is angled in the same manner as the putter.
Further, by providing an angle in the horizontal direction, it is possible to cope with prevention of slice balls and hook balls.
The tip can be replaced with a tip with a different lie angle according to each user's preference. When used as a stick, [FIG. 8] (2) The tip can be replaced with a tip.
7). New hole shape and structure As the size of snack golf balls increases, the diameter of the holes will also increase.
In the case of sharing with golf, the shape / structure may be such that a hole is dug in the size of a snack golf hole as shown in FIG. 9 and a frame that is the size of a conventional golf hole is set.
In addition, as shown in [Fig. 9], with a structure with a circular spring with a spring, and a structure that does not go out once inside, it is placed on the ground without digging holes. What is necessary is just to fix a position with a pin as a shape and a structure.
