Description

[Technical field]

[0001] The present invention relates to a method and system for creating a golf club indicator. [Background technology]

[0002] For example, in order to set up a golf club in a square stance and hit the ball in the desired direction (hereinafter also referred to as the target direction), it is preferable to point the face surface toward the target direction. If the face surface does not face the target direction, the face surface will tilt at the time of impact and the ball will not fly straight. For this reason, there are golf clubs that have an index to align the face surface with the target direction.

[0003] Patent Document 1 discloses a golf club with a center line marked on the top surface of the club head that extends in the direction in which the face faces. When the club head is viewed from directly above, this center line appears to be a straight line perpendicular to the face.

[0004] However, when holding a golf club such as an iron or a driver, the user looks down at the club head from diagonally above. In this case, the center line of Patent Document 1 appears to be curved along the curved upper surface of the club head, making it difficult to align it with the target direction.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 09-262323 Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE PRESENT EMBODIMENTS The main object of the present invention is to create an index that allows a user holding a golf club to easily align the face surface in a predetermined direction. [Means for solving the problem]

[0007] The method for creating a golf club indicator of the present invention is characterized by comprising a first step of drawing a first light ray extending along the direction in which the face surface faces the floor using light emitted from a first light source attached to a golf club, and a user holding the golf club so that the first light ray faces a predetermined direction; a second step of drawing a second light ray parallel to or overlapping with the first light ray on the club head using light emitted from a second light source installed in front of the head of the user holding the golf club; and a third step of creating an indicator on the club head based on the second light ray.

[0008] According to the present invention, by marking an index along the second ray drawn on the club head, an index that forms a straight line along a predetermined direction can be created on the curved or bent surface of the club head when seen by a user who holds the golf club so that the face surface faces the predetermined direction. As a result, when holding the golf club, the face surface can be directed in the predetermined direction simply by aligning the extension direction of the index with the predetermined direction.

[0009] Also, when an index is marked on the curved or bent surface of the club head, the posture of the club head can be made constant simply by aligning the index with a specified direction. This allows the player to develop the habit of holding the club head in a constant posture. Furthermore, in this case, if the face surface is not facing the specified direction when the golf club is held, the index does not appear to be straight, so the player can intuitively determine whether the face surface is facing the specified direction or not.

[0010] For example, in the second step, when the user takes a square stance, it is generally preferable to orient the face toward the target direction. On the other hand, when the user takes an open or closed stance, it is preferable to orient the face toward a direction tilted clockwise or counterclockwise from the target direction in order to hit the ball toward the target direction. In other words, the direction in which the face should be orientated is determined by the stance and the target direction.

[0011] Therefore, the predetermined direction may be determined based on the stance of the user holding the golf club and the target direction.

[0012] A specific embodiment of the third step is to mark the indicator continuously or intermittently in a straight line along the second light beam.

[0013] A more specific embodiment of the third step is to mark at least a portion of the indicator along a curved or bent surface of the club head.

[0014] For example, if a target indicating a specific direction is placed on the floor of a room, the first light beam can be directed in the specific direction simply by aligning the first light beam with the target; however, if the target is placed at a position higher than the floor, such as on a wall, it is difficult to align the first light beam with the target.

[0015] Therefore, the first light source may emit a line of light along a vertical plane when the golf club is held in a position. With this configuration, it becomes easier to apply the line of light to a target even if the target is placed at a position higher than the floor surface.

[0016] A specific embodiment of the second light source is one in which the second light source is placed in front of the eyes of a user who holds the golf club and looks at the club head, and emits light in the viewing direction.

[0017] The golf club index creating system of the present invention is characterized by comprising a first light ray drawing device which is attached to a golf club and has a first light source which draws a first light ray extending on the floor surface in front of the face in the direction the face faces, and a second light ray drawing device which is attached to a user and has a second light source which draws a second light ray on the club head which is parallel to or overlaps with the first light ray when the user holds the golf club so that the first light ray faces a predetermined direction.

[0018] According to the present invention, for example, a linear indicator can be created along a predetermined direction when viewed from a user who holds a golf club so that the face surface faces the predetermined direction with respect to a curved or bent surface of a club head. As a result, when holding a golf club, the face surface can be oriented in the predetermined direction simply by aligning the extension direction of the linear indicator with the predetermined direction.

[0019] The first light beam drawing device may further include a spherical main body attached to the face surface, and a first light source may be installed on the main body.

[0020] According to this configuration, the first light source rendering device has a golf ball shape, and the user can hold a golf club with the image of actually hitting a ball.

[0021] The second light beam drawing device may further include an attachment mechanism that is interposed between the user and the second light source and that attaches the second light source in front of the user's eyes. With this configuration, light can be emitted along the line of sight of the user.

[0022] The golf club according to the present invention is characterized in that the club head is provided with indicators that are marked continuously or intermittently so as to form a straight line along a specified direction when viewed by a user holding the golf club with the face surface facing the specified direction.

[0023] According to the present invention, the face surface can be oriented in a predetermined direction simply by holding the golf club so that the direction in which the index extends is aligned with the predetermined direction.

[0024] It is also preferred that at least a portion of the indicia is marked along a curved or bent surface of the club head.

[0025] With this configuration, if the face surface is not facing the specified direction, the indicator does not appear to be linear to the user holding the golf club, and therefore the user can intuitively determine that the face surface is not facing the specified direction. Effect of the Invention

[0026] According to the present invention, an index is obtained that allows a user holding a golf club to easily align the face surface in a predetermined direction, and as a result, the user can develop a habit of holding the club with the face surface facing the predetermined direction.

[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an index creating system, an index creating method, and a golf club according to the present invention will be described with reference to the drawings.

[0029] The index creating system and index creating method according to the present invention are for creating an index for a golf club to be used when orienting the face surface in a predetermined direction when addressing the club, etc. This index is particularly effective for golf clubs where the user looks down on the club head from diagonally above when addressing the club, specifically golf clubs other than putters (drivers, fairway woods, utilities, irons, or wedges), but may also be used for putters.

[0030] <Embodiment> An index creating system 100 according to this embodiment includes a first light beam drawing device 10 attached to a golf club X, and a second light beam drawing device 20 attached to a user A, as shown in FIG.

[0031] The first light beam drawing device 10 includes a first light source 11 that draws a first light beam L1 on the floor surface S of the club head X1, the first light beam L1 extending in the direction in which the face surface Xs faces. In this embodiment, the first light beam L1 is drawn on the floor surface S in front of the face surface Xs, the first light beam L1 extending in the direction in which the face surface Xs faces. The first light source 11 emits a line light beam l1 that spreads in a fan shape. The floor surface S also includes the ground.

[0032] 2, the first light beam drawing device 10 further includes a mounting fixture 12 for mounting the first light source 11 to the golf club X. The mounting fixture 12 in this embodiment is configured to mount the first light source 11 to the face surface Xs, but is not limited thereto, and the first light source 11 may be mounted at a location other than the face surface Xs of the golf club X, for example, on the upper surface Xa or shaft of the club head X1.

[0033] Specifically, the mounting fixture 12 of this embodiment includes a spherical main body 13 and a base 14 protruding from the surface of the main body 13. The main body 13 has the same diameter as a golf ball, and holds the first light source 11 so that light is emitted from the hemisphere opposite to the hemisphere from which the base 14 protrudes. A magnet is built into the base 14, and the base 14 is detachably magnetically attached to the face surface Xs by the magnetic force of the magnet.

[0034] In addition, the fixture 12 of this embodiment is configured so that the main body 13 and the base 14 are also detachably attached by magnetic force. The fixture 12 further includes an angle adjustment mechanism 15 interposed between the main body 13 and the base 14 for adjusting the angle of the light emitted from the first light source 11 with respect to the floor surface S. Specifically, the angle adjustment mechanism 15 includes a convex guide 15a extending along a circumference that cuts the main body 13 so as to pass through the center and the light emission port, and a groove 15b formed on the contact surface of the base 14 with the main body 13 and into which the guide 15a fits. The angle of the light can be adjusted by sliding the main body 13 relative to the base 14 while fitting the guide 15a into the groove 15b.

[0035] 1, the second light beam drawing device 20 includes a second light source 21 that is installed in front of the head of the user A, more specifically, in front of the eyes. The second light source 21 emits light in front of the head, more specifically, in front of the eyes. The second light source 21 also emits a line light l2 that spreads in a fan shape.

[0036] 3, the second light beam drawing device 20 further includes an attachment mechanism 22 for attaching the second light source 21 to the user A. The attachment mechanism 22 in this embodiment is configured to attach the second light source 21 to the brim of a hat worn by the user A, but is not limited thereto, and may be attached to other wearable items such as glasses or the user himself / herself. The attachment mechanism 22 includes a position adjustment mechanism for aligning the position of the second light source 21 in front of the user's eyes, and a direction adjustment mechanism for adjusting the direction of light emitted from the second light source 21.

[0037] Specifically, the attachment mechanism 22 of this embodiment includes a clip 23 that clamps the flange, a cylindrical holder 24 that holds the second light source 21, and a shaft 25 that connects the clip 23 and the holder 24 to each other. The shaft 25 includes an inner cylinder 25a and an outer cylinder 25b, and the position of the second light source 21 can be adjusted by sliding these relative to each other, which serves as a position adjustment mechanism. In addition, a ball joint 26 is interposed between the holder 24 and the shaft 25, and the direction of the light emitted from the second light source 21 can be adjusted by adjusting the direction of the holder 24 with the ball joint 26, which serves as a direction adjustment mechanism.

[0038] Next, a procedure for creating an index using the index creating system 100 according to this embodiment will be described with reference to Figs. 4 to 6. In this embodiment, a case where the user sets up with a square stance will be described. In this case, it is preferable to orient the face surface Xs toward a target direction when setting up the golf club.

[0039] First, the first light beam drawing device 10 is attached to the face surface Xs, and the second light beam drawing device 20 is attached to a hat worn by the user A.

[0040] Next, the first light source 11 is turned on, and the light emitted from the first light source 11 draws a first light ray L1 on the floor surface S in front of the golf face Xs, extending in the direction in which the golf face Xs faces, and the user A holds the golf club X so that the first light ray 11 faces the target direction (first step).

[0041] Specifically, as shown in Fig. 3(a), a line of light l1 emitted from the first light source 11 is directed at a target P installed on a wall in the target direction, and the orientation of the first light source 11 is adjusted so that the line of light l1 is emitted along a vertical plane. As a result, a first light ray L1 extending toward the target direction is drawn on the floor surface S in front of the face surface Xs, as shown in Fig. 5. At this time, the angle of the light emitted from the first light source 11 is adjusted using the angle adjustment mechanism 15 so that the line of light 11 draws the first light ray L1 on the floor surface S while striking the target P.

[0042] Next, the second light source 21 is turned on, and the light emitted from the second light source 21 draws a second light ray L2 that is parallel to or overlaps with the first light ray L1 on the club head X1 (second step).

[0043] Specifically, as shown in FIG. 3(b), the user A looks at the golf club head X1 while holding the golf club X, and adjusts the position adjustment mechanism so that the second light source 21 is located in front of the eyes, more specifically, between the eyes, i.e., in front of the eyebrows. Then, the orientation adjustment mechanism adjusts the orientation of the second light source 21 so that the line light l2 emitted from the second light source 21 passes through the club head X and is parallel to or overlaps with the first light ray L1. In this state, the second light source 21 emits light in the viewing direction of the user A who looks at the club head X1. More specifically, the second light source 21 is located on a virtual line connecting the eyes of the user A and the club head X1, and emits the line light l2 along the virtual line. As a result, as shown in FIG. 6, the second light ray L2 is drawn, which passes through the club head X and is parallel to or overlaps with the first light ray L1. In this embodiment, the line light l2 passes through the face surface Xs and the top surface Xa of the club head X1.

[0044] Then, as shown in FIG. 7(a), an index L is marked on the club head X in the form of a straight line along the second light ray L2. This index L may be marked along the second light ray L2 as seen by the user A holding the golf club X, and may be recognized as a straight line drawn by the second light ray L2. In this embodiment, the index L is a straight line continuously marked on the second light ray L2 from the face surface Xs to the upper surface Xa so as to pass through the curved or bent surface of the club head X1, but is not limited to this. For example, the index L may be a plurality of points intermittently marked on the second light ray L2. In addition, the index L is preferably directly marked on the club head X, and may be written with ink or engraved, for example.

[0045] However, the task of drawing the index L on the second light ray L2 is difficult for a single user. This is because the second light ray L2 is shifted when the user crouches down to draw the index L. Therefore, a guide portion 30 may be provided on the club head X in advance to allow the user to memorize the position where the second light ray L2 passes. As shown in FIG. 8, the guide portion 30 in this embodiment is a coordinate sticker on the surface of the club head X to make it easier to memorize the coordinates on the surface, and this coordinate sticker has a lattice pattern printed on it. In this way, the user can memorize the pattern as to which position on the coordinate sticker the second light ray L2 passed in the second step, and draw the index L based on that memory, allowing the user to draw the index L by himself.

[0046] According to this embodiment, a linear indicator can be created on the curved or bent surface of the club head X1, which is aligned with a predetermined direction when viewed from a user who holds the golf club X so that the face surface Xs faces the predetermined direction. As a result, when holding the golf club, the face surface can be oriented in the predetermined direction simply by aligning the extension direction of the linear indicator with the predetermined direction.

[0047] Also, a user holding the golf club X can intuitively tell whether the face surface Xs is facing the target direction or not. In other words, if the index L is marked on the curved or bent surface of the club head X in this way, as shown in Fig. 7(b), if the face surface Xs is not facing the target direction, the index L appears bent to a user holding the golf club X. This allows the user to intuitively tell whether the face surface Xs is facing the target direction or not.

[0048] <Other embodiments> The index creating system and the index creating method according to the present invention are not limited to the above embodiment. For example, in the above embodiment, a line is marked as an index, but the present invention is not limited to this, and may be a point. Specifically, as shown in FIG. 9(a), the index may be three or more points marked on the curved or bent surface of the club head X1. When the index L is three or more points marked on the curved or bent surface of the club head, the straight line connecting the points that is visible when the user is holding the golf club may be directed in a predetermined direction. In the above embodiment, the index is newly marked on the club head, but the index may be marked by utilizing the structure that the club head originally has. Specifically, as shown in FIG. 9(b), a plurality of face lines XL formed on the face surface Xs may be formed so that one end is aligned on the second light ray l2, and the one end may be used as a part of the index L. In this case, one end of each face line XL becomes an intermittently marked index. It should be noted that the indicator L is not limited to being partially marked on the curved or bent surface of the club head X1, and the entire indicator L may be marked on the curved or bent surface of the club head X1.

[0049] In the above embodiment, the case where the user takes a square stance has been described, but when the user takes an open or closed stance, for example, it is preferable to orient the face in a direction tilted clockwise or counterclockwise from the target direction in order to hit the ball in the target direction. Therefore, when the user takes a stance other than the square stance, in the first step, it is sufficient to orient the face in a predetermined direction suitable for the stance, so that the first light ray L1 is oriented in a direction suitable for the stance. An indicator suitable for each stance can be created by following the same procedure as in the embodiment.

[0050] The position adjustment mechanism and orientation adjustment mechanism of the attachment mechanism are not limited to those in the above embodiment. For example, the clip and the holder may be connected by an arm having multiple joints, and the arm may function as the position adjustment mechanism and orientation adjustment mechanism. By using ball joints for the multiple joints, the degree of freedom in adjusting the position and orientation is increased.

[0051] In the above embodiment, the first light beam drawing device is attached to the face surface, but in this embodiment, the ball cannot be test-hit with the first light beam drawing device attached. Therefore, the first light beam drawing device may be attached to a location other than the face surface of the golf club, for example, the upper surface of the club head or the shaft. In this case, for example, after using a light source attached to the face surface as in the above embodiment to draw a light beam extending along the direction in which the face surface faces, a first light source drawing device attached to the shaft may draw a light beam parallel to or overlapping with the light source, and this light beam may be used as the first light beam.

[0052] In the above embodiment, the second light beam drawing device is provided with an attachment mechanism for attaching the second light beam drawing device to the user, but the present invention is not limited to this. For example, the second light source may be provided with a stand for supporting the second light source, and the stand may be used to set the second light source in front of the user's head. In this case, the stand may be provided with a position adjustment mechanism and a direction adjustment mechanism.

[0053] In addition, parts of the various embodiments may be combined or modified as long as it does not go against the spirit of the present invention. [Explanation of symbols]
