Description

The present invention relates to a golf practice tool that determines a golf player's posture at address.

Golf may seem like a simple sport because it involves hitting a stationary ball, but in order for golf players to hit the ball in the desired direction and distance, they must maintain the best body posture to impact the ball. Beginners don't know what posture to use to hit the ball, so even when they hit the ball, they have trouble determining the direction. Particularly difficult are the angle of forward inclination of the upper body and the degree of rotation of the upper body during the backswing. In other words, in order to determine the direction of the ball and increase the flight distance of the ball, it is necessary to swing the golf club appropriately. It is necessary to properly lean forward and rotate the upper body when hitting the ball.

FIG. 1 is a diagram showing a backpack-type golf practice tool 10 of the present invention. As shown in FIGS. 3 to 5, the backpack-style golf practice tool of the present invention is carried on the golf player's back in the same way as a school bag or backpack for practice. Therefore, it may also be called a school bag (rucksack) type golf practice tool. The backpack-type golf practice tool 10 of the present invention (hereinafter also simply referred to as a golf practice tool) includes a column-shaped backpack-type golf practice tool main body 11, and a backpack-type golf practice tool main body 10 that is carried on the back and worn on the left and right shoulders of a golf player. It is composed of shoulder belts (shoulder straps) 16 and 18.

The backpack-type golf practice tool body 11 has a columnar shape, and the part that comes into contact with the back (back-contacting part) 14 is a side surface (of the columnar part) of the backpack-type golf practice tool main body 11, and has a substantially rectangular planar shape. be. That is, the backpack-type golf practice tool main body 11 has a shape in which a columnar portion is cut in a direction perpendicular to the columnar bottom surface. The backpack-type golf practice tool main body 11 shown in FIG. 1 has a columnar shape (which may also be referred to as a partial columnar shape or a cut columnar shape) in which a column with a circular bottom is cut in a direction perpendicular to the circular bottom. The partial circle may be a semicircle, a partial circle wider than a semicircle, or a partial circle narrower than a semicircle, depending on the golf player's body and skill level. The back contact portion may be uneven so that it can easily contact the back.

In addition to the circular shape shown in FIG. 1, the bottom shape may be an ellipse, a triangle, a rectangle (rectangle or square), a polygon, or any curved shape, or a shape similar to these. In addition, in the case of a polygonal shape such as a triangular shape, the back contacting portion 14 that contacts the back may be a part of the side surface thereof (that is, it does not have to be a cut surface).

The portion 14 that the back contacts (back contact portion) has a planar shape in FIG. 1, but may have an uneven portion. The formation of the uneven portion makes it difficult for the contact portion 14 to move on the back, so that the backpack-type golf practice tool main body 11 is stabilized on the golf player's back. Alternatively, the back contact portion 14 may be formed in a shape that fits (fits) the shape of the back. In this case as well, the contact portion 14 becomes difficult to move on the back, so the backpack type golf practice tool main body 11 is stabilized on the golf player's back. Alternatively, if a flexible member is attached to the abutting portion 14 (or the abutting portion 14 itself is a flexible member), the abutting portion 14 deforms and fits according to the shape of the back, and the abutting portion 14 moves. Since it becomes difficult to carry, the backpack type golf practice tool main body 11 is stabilized on the golf player's back. Moreover, since the flexible material touches your back, you won't feel any discomfort, and you won't feel tired even during long hours of practice. The flexible member is, for example, flexible plastic, various rubbers, or various sponges, and the flexible plastic is, for example, urethane resin or vinyl chloride (PVC). Alternatively, an air mat (air pad) containing gas such as air may be used.

Both ends of the shoulder belts 16 and 18 are fixed to the back contact portion 14 or the outer side surface 13 of the backpack-type golf practice tool main body 11. Put the shoulder belt 16 on your right shoulder, put the shoulder belt 18 on your left shoulder, adjust the lengths of the shoulder belts 16 and 18 with the length adjustment parts 17 and 19, and put the main body 11 of the backpack-style golf practice tool on a predetermined part of your back. Avoid moving from your back. Alternatively, the waist belt 20 may be attached to the backpack-type golf practice tool main body 11 to further prevent the backpack-type golf practice tool main body 11 from moving. Reference numeral 21 denotes a length adjustment portion for adjusting the length of the waist belt 20. Both ends of the waist belt 20 are fixed to the lower back abutting portion 14 of the backpack-type golf practice tool main body 11 or to the outer side surface 13 of the backpack-type golf practice tool main body 11.

Striped patterns 31, 32, and 33 are formed on the top surface (bottom surface) 12 of the main body 11 of the backpack-type golf practice tool of the present invention. The striped patterns 31 to 33 define the angle of inclination of the golf player's upper body, as will be shown later. It is preferable that the striped patterns 31 to 33 be drawn approximately parallel to the back contact portion 14 in order to facilitate defining the angle of inclination. Furthermore, since it is easier to depict the striped patterns 31 to 33 in a straight line, manufacturing costs can be reduced. Of course, it can also be made in a curved shape. If it is linear, it may be called a striped line. The number of striped patterns 31 to 33 may be greater. However, if there are too many angles, it becomes difficult to specify the inclination angle, so it may be adjusted according to the proficiency level of the golf player. You can also change the color and brightness of the striped pattern to make it easier to see. Further, the striped patterns 31 to 33 may be color-coded, or may be color-coded by color pattern.

As shown in FIG. 1, striped patterns 35, 36, and 37 are also formed on the side surface 13 of the backpack-type golf practice tool main body 11 of the present invention. Since FIG. 1 is a perspective view, the back side of the side surface 13 of the backpack-type golf practice tool main body 11 is not visible, but a similar striped pattern is formed on the side surface 13 on the back side of the side surface 13. The striped patterns 35 to 37 define the rotation angle of the golf player's upper body, as will be shown later. The striped patterns 35 to 37 are preferably drawn approximately perpendicular to the top surface (bottom surface) 12 in order to easily define the angle of inclination. Furthermore, since the striped patterns 35 to 37 are easier to depict if they are linear, manufacturing costs can be reduced. Of course, it can also be made in a curved shape. The number of striped patterns 35 to 37 may be greater. However, if there are too many angles, it becomes difficult to specify the inclination angle, so it may be adjusted according to the proficiency level of the golf player. You can also change the color and brightness of the striped pattern to make it easier to see. Further, the striped patterns 35 to 37 may be color-coded, or may be color-coded by color pattern.

FIG. 2 is a diagram showing three views (a plan view, an elevation view, and a side view) of the backpack-type golf practice tool main body 11 shown in FIG. 1. FIG. 2(a) is a plan view (top (bottom) view), and FIG. 2(a) is an elevational view (front view) seen from above (above), and FIG. 2(c) is a side view. The figure seen from direction A shows the back contact portion 14 of the backpack type golf practice tool main body 11, and since this back contact portion 14 is not used for practice, it does not need to have a pattern. The pattern in FIG. 2 is depicted as a substantially rectangular colored pattern. Such color patterns can also be used to practice regulating a golf player's posture. FIG. 2(a) shows the upper surface 41 of the main body 11 of the backpack-type golf practice tool, in which substantially rectangular color patterns 46, 47, 48, 49, and 50 are formed. Using these color patterns 46 to 50, a golf player can practice defining the degree of inclination of the upper body of the golf player, as will be shown later. The number of color patterns 46 to 50 may be smaller or larger, and can be adjusted according to the golf player's skill level.

FIG. 2(b) is an elevational view (front view) seen from the direction opposite to direction A, and is a view showing the side surface 42 of the backpack-type golf practice tool main body 11. When worn on the back, vertically long rectangular color patterns 51, 52, 53, 54, 56, 57, and 58 are formed. FIG. 2(c) is a side view seen from a direction perpendicular to direction A, and is a view showing the side surface 43 of the backpack-type golf practice tool main body 11, when the backpack-type golf practice tool main body 11 is carried on the back. Vertically long rectangular color patterns 61, 62, 63, 64, 65, and 66 are formed on. Since the side surface of the backpack-type golf practice tool body 11 is a curved surface, even if the widths of the rectangular colored patterns 51 to 58 and 61 to 66 are the same, the widths in the elevation view (b) and the side view (c ), the width changes, but that change is not taken into account. The larger the pattern change between adjacent objects, the easier it is to visually recognize them, making it easier to remember the degree of inclination and rotation. Additionally, the number of color patterns can be increased or decreased to match the golf player's skill level. Although the upper surface and side surfaces are filled with colored patterns in FIG. 2, the same applies to the case of a striped pattern (which may also be called a striped line) as shown in FIG. Such a striped pattern can also be produced by pasting colored tapes of various colors, for example. If the tape is colored, it can be changed to suit the skill level of the player, and the color can also be changed according to the player's preference. Additionally, once a player's style is fixed, you can stick colored tape in a noticeable color to ensure it stays that way.

FIG. 3 is a diagram illustrating a method of using the backpack-type golf practice tool of the present invention, and is a diagram illustrating a golf player practicing while carrying the backpack-type golf practice tool of the present invention on his back. In order for a golf player to hit the ball in the appropriate direction and increase the flight distance of the ball, it is necessary to swing the golf club appropriately. It is necessary to maintain an appropriate angle (referred to as the forward leaning posture angle). Based on past experience and research, the appropriate forward leaning angle during the swing is said to be 30 to 35 degrees, but this naturally varies depending on the golf player's physique, athletic ability, technical level, etc. In other words, you need to know the forward tilt angle that suits your condition (physique, athletic ability, skill level, etc.). By using the backpack-type golf practice tool of the present invention, it is possible to easily set the forward tilt angle to a constant angle that suits one's own condition.

FIG. 3 is a side view of the state of the body when the backpack-type golf practice tool 10 of the present invention is carried on the back, leaning forward and impacting (hitting) a ball. Golf players practice while visualizing the state of their body when they make an impact, in order to imagine what it would be like to impact (hit) a ball and get into that state. However, it is very difficult to imagine what the forward leaning posture is like without a standard, and it is difficult to achieve the posture you envisioned during the actual swing. When the backpack-type golf practice tool 10 of the present invention is used, as shown in FIG. Reflected in mirror 73.

Striped patterns 31 to 33 are drawn on the upper surface 12 of the main body 11 of the backpack-type golf practice tool, so the striped pattern (in this case, the striped line 32) appearing above the head 74 of the golf player 71 is indicated by an arrow. It moves like 75 and is reflected in mirror 73. The golf player 71 can check the striped line pattern 32 reflected in the mirror 73 placed in front of him and can visualize his own forward leaning posture. If it is better to reduce the forward tilt angle, the striped pattern 33 or the space between the striped patterns 32 and 33 may be reflected in the mirror 73. If it is better to increase the forward tilt angle, the striped pattern 31 or the space between the striped patterns 32 and 31 may be reflected in the mirror 73. In this way, you can easily know your forward leaning (posture) angle visually, and you only need to memorize that state. If you don't have a mirror, you can ask someone else to look at it and tell you.

FIG. 4 is a front view of the golf player 71 carrying the backpack-type golf practice tool 10 shown in FIG. 3 on his back. That is, the shoulder belts 18 and 19 are placed on the shoulders of the golf player 71, and the waist belt 20 is also used to secure the main body 11 of the backpack-type golf practice tool to the back of the golf player 71, and the golf player 71 is in a forward leaning posture. . As can be clearly seen when viewed from the front of the golf player 71, the upper surface 12 of the backpack-type golf practice tool main body 11 is visible, and the striped line (striped pattern) 32 is visible above the head 74 of the golf player 71. While imagining this forward-leaning posture, the golfer should assume this forward-leaning posture when swinging the golf club and impacting the ball with the golf club. If you swing the golf club and impact the ball with this image in mind, you can see in which direction and how far the ball will fly based on the forward leaning angle.

If the direction and flight distance are insufficient, you can simply change the forward lean angle. For example, if you want to increase the forward leaning posture angle, you can make it so that the area between the striped lines 32 and 31 can be seen in the mirror above the head 74; The striped line 31 should be aligned. Alternatively, if you want to reduce the forward leaning posture angle, you can make the area between the striped lines 32 and 33 visible in the mirror above the head 74, or if you want to make the forward leaning posture angle even smaller, you can The striped line 33 should be aligned. As described above, by using the backpack-style golf practice tool main body 11 of the present invention, you can visually visualize your own forward leaning posture angle and set it to a certain angle, so that you can fly in the desired direction and the desired distance. You can hit the ball with. In addition, in FIG. 3, the shoulder belts 16 and 18 are placed over the left and right shoulders, and the waist belt 20 is placed around the waist to secure the main body 10 of the backpack-type golf practice tool to the back during posture correction practice or golf club swing practice. It is also important to prevent the main body 10 of the backpack-type golf practice tool from moving.

Golf players want to hit the ball as far as possible, so the posture of the backswing and the speed at which the golf club is swung down are important. The important thing about posture during the backswing is to rotate the hips and shoulders appropriately. The degree of rotation of the hips and shoulders also determines the speed at which the golf club is swung down. It is said that at the top of the backswing, it is ideal for the hips to rotate 45 degrees and the shoulders to rotate 90 degrees, but it is important to know the optimal degree of rotation based on the golf player's physical ability and skill level. . FIG. 5 is a diagram showing the top state of a backswing with the backpack-type golf practice tool of the present invention worn on the back. When the golf player 71 rotates the waist and shoulders of the upper body in the direction of the arrow 77 while suppressing the movement of the lower body and keeping the axis of the body, as shown in FIG. The practice tool main body 11 rotates, and the vertical striped line pattern drawn on the side surface 13 of the backpack-type golf practice tool main body 11 becomes visible from the front of the golf player 71. In FIG. 5, vertical striped line patterns 36 and 37 are visible. From this state, it is possible to know how far the ball will fly when the ball is swung down with the golf club and makes an impact. If you practice by understanding the degree of twist (rotation) of your upper body based on this striped pattern, you will be able to achieve a nearly constant distance. In this way, by using the backpack-type golf practice tool of the present invention, you can see how the striped pattern looks when you twist (rotate) your body using the mirror placed in front of you. You can practice by yourself without borrowing. Also, even if you don't have a mirror, you can have someone else look at you and tell you what you are doing.

The lighter the main body of the backpack-type golf practice tool of the present invention is, the more comfortable it can be carried on the back. For example, the main body of the backpack-type golf practice tool is made of fibers such as plastic and paper. Examples of plastics include polyvinyl chloride (PVC) and polyurethane. Since polyvinyl chloride (PVC), polyurethane, and the like are flexible plastics, there is no problem of physical pain even if the main body of the backpack-style golf practice equipment hits the body directly. Especially for children, it is important not to make them feel uncomfortable. Of course, various other flexible plastics can also be used. Also, if it is made of foamed plastic, it will be quite lightweight, so even children can easily carry it on their backs. Examples of foamed plastic include urethane foam, styrofoam, and propylene foam. If the inside is hollow, it will be considerably lighter, so the outside (outer layer) material can also be made of metal (iron, stainless steel, or various alloys). Even if it is made of metal, to make it even lighter, it may be made of titanium, its alloy, aluminum, or its alloy, for example. Alternatively, it may take a predetermined shape (for example, a partially cylindrical shape, a partially elliptical column shape, a rectangular column shape, a trapezoid column shape, a polygon column shape) when folded and opened. Alternatively, it may be manufactured by mixing various plastics or by combining various materials. Alternatively, the inside may be made of foamed plastic such as styrofoam, and the surface may be made of another plastic material, cloth, or the like. For example, the surface of the foamed plastic can be covered with polyvinyl chloride or cloth. In that case, it is also possible to print a striped pattern on the surface (coating) material. In this case, if the surface (coating) material becomes dirty, it can be replaced or washed. If the shape of the columnar box is a trapezoidal column with a substantially trapezoidal bottom, the side of the trapezoid corresponding to the long base of the trapezoid (called the long base) is the side that comes into contact with the back (called the back contact side). Become. When the shape of the columnar box is a polygonal column with a substantially polygonal bottom surface, one of the side surfaces of the polygonal column becomes a surface that comes into contact with the back (referred to as a back-contacting side surface).

Alternatively, if you make it into a balloon, you can deflate it when not in use and inflate it with air, nitrogen, or other gas only when you want to use it, and it won't take up much space when you store it, so you can store it anywhere. Since it is not heavy, it can be hung on the wall for storage. In the case of a balloon type (balloon body), the frame body may be manufactured so that it takes on a predetermined shape (for example, partially cylindrical, partially elliptical cylindrical, rectangular cylindrical, trapezoidal cylindrical, polygonal cylindrical) when inflated. It may be arranged so that it takes on a predetermined shape only when it is inflated. The outer (outer layer) material is rubber, stretchable elastomer, cloth, or paper. In the case of a balloon body, it is considerably lighter, so you can play with it in almost the same condition as an actual plate.

FIG. 9 is a diagram showing a modified embodiment of the partially cylindrical backpack-type golf practice tool shown in FIG. 1. Shoulder belts and waist belts are not listed. In this embodiment, a border portion 25 is provided between the outer side surface 13 of the backpack-type golf practice tool main body 11 and the back contact portion 14. By providing the border portions 25 and 26 on both sides, the back, arms, and head are less likely to hit the corners, making it easier to move the body. Even if the back contact portion 14 is wider than the back, if the edges are trimmed so that it is approximately the same as or narrower than the back, it becomes easier to carry the backpack-type golf practice equipment on the back, and the body becomes easier to move and play. Furthermore, if there is no edged portion as shown in FIG. 1, the angle of the corner portion is small and the corner portion is likely to be damaged, but by providing the edged portion 25, damage can be prevented. The border portions 25 and 26 may be flat or curved, or may be modified as appropriate. In the present invention, the term "partial cylindrical shape" includes not only cases with such edging, but also shapes similar to these. The top and bottom surfaces may not be flat, but may be curved surfaces with a bulge or slightly concave curves. Furthermore, the scope of the present invention also includes cases in which a slightly uneven curved surface is formed on the side surface or a similar curved surface. Furthermore, various other columnar shapes also include shapes similar to those described in this specification.

Since it is a practice tool that is carried on the back of a person, its size is almost self-evident from the figures and descriptions given so far, but the approximate size of the backpack-type golf practice tool of the present invention will be estimated. FIG. 8 is a diagram showing a backpack-type golf practice tool having a partially cylindrical shape, and is the same diagram as FIG. 1, and is a diagram showing dimensions. That is, FIG. 8 is a diagram showing the approximate size of the backpack-type golf practice tool. (Refer to Fig. 1 for reference numbers) The radius r of the bottom surface 12 of the partial cylinder 11 is about 10 cm to 40 cm, the height of the partial cylinder 11 (length of the back contact part) is about 20 cm to 80 cm, and the shape of the partial circle is centered It is determined by the angle α, which is approximately 120 degrees to approximately 300 degrees, and the width d of the contact portion is determined by r and α, which is approximately 15 cm to 80 cm. Of course, it is possible to make the size smaller or larger than the above size. The backpack-type golf practice tool of the present invention can be used by both children and large adults, so the size can be appropriately determined according to each person's body size.

FIG. 6 is a second invention similar to the present invention described above, and is a diagram showing a (bracelet type) golf practice arm supporter (also referred to as an arm supporter type golf practice tool) 80. The condition of the arm is important in controlling the direction and speed of the ball. FIG. 6 is a diagram showing an arm supporter 80 for golf practice that is wrapped around the arm (bracelet type). The arm supporter for golf practice has a flexible cylindrical shape, the arm is passed through the cylindrical hole 92, and the approximately middle part of the arm supporter for golf practice is applied to the elbow part. Around the outer side of the arm supporter for golf practice, vertical striped line patterns (vertical striped patterns) 82 to 91 are drawn in the length direction of the arm, similar to the above-mentioned columnar backpack-type golf practice tool. Since it is around the outer side, a vertical striped line pattern is also depicted on the opposite side, which is not visible in FIG.

FIG. 7 is a diagram showing an example of how to use the arm supporter for golf practice (bracelet type golf practice tool) of the present invention. The state of the golf player shown in FIG. 7 is during the backswing, and the left arm is extended and brought close to the chest. The arm supporter 80 for golf practice is passed through the left arm, and its middle portion is placed against the elbow of the left arm (indicated by a broken line 93). Vertical striped line patterns 94 to 97 are depicted on the arm supporter 80 for golf practice (the number is even greater since there are also areas that are not visible). It is better to extend the left arm as straight as possible, so it is better to make the vertical stripe pattern as straight as possible. Since this can be visually confirmed (indicated by the broken line arrow in FIG. 7), the condition of the left arm can be brought closer to the ideal condition. Also, if you want to control the direction by twisting your left arm, color-code the vertical striped line pattern (so-called striped pattern, but you can also call it a striped pattern including the striped line pattern), and place it in an appropriate position. You can hold your left arm when a vertical stripe pattern of a predetermined color appears on the screen. Alternatively, the vertical striped line pattern may be numbered and matched with the vertical striped line pattern of that number. The arm supporter for golf practice of the present invention can also be used for bending the elbow. For example, it is also possible to set the angle at which the elbow is bent or the angle at which the elbow is twisted by passing the golf practice arm supporter of the present invention through the elbow.

The golf practice arm supporter of the present invention is made of rubber, cloth, paper, and various elastic materials. The size of the inner ring should be large enough to fit around the arm, and the inner ring may be larger than the circumference of the arm as long as it can be secured to the arm with rubber bands at both ends. In addition, if it is a stretchable member such as rubber, the inner size of the ring may be smaller than the circumference of the arm, and after passing it around the arm, it will fit and be fixed so as to tighten the arm to some extent. Note that instead of the vertical striped line pattern, a vertical striped color pattern similar to that shown in FIG. 2 (which may be considered as a thickened striped line) may be used. It may also be used on other parts of the arm, such as the wrist. That is, it is also possible to grasp the twisted state of the wrist using the arm supporter for golf practice of the present invention. In this case, it can also be called a wrist supporter for golf practice.

Recently, an increasing number of elementary school students are playing golf, and it is more effective to teach them visually than by theory, and if you use visuals, they will be more interested and learn faster. The invention is also particularly suitable as an educational tool for such children. Instructors can also check directly with their own eyes, and training for beginners is easy. Also, you can practice by yourself using a mirror. You can secretly improve your golf skills.
