Description

[Technical Field]

[0001] The present invention relates to a line marker, and more particularly to a line marker for drawing a line on the surface of a golf ball. [Background technology]

[0002] 2. Description of the Related Art Conventionally, when putting, a line is drawn on the golf ball to indicate the direction to the cup. For example, Patent Document 1 proposes a marking tool for drawing such a line on a golf ball, which includes an annular portion having an inner diameter roughly equal to the diameter of the golf ball, a plurality of pillars arranged on the annular portion to form a hemispherical space inside, and a guide groove that penetrates the pillars and displays an imaginary line pointing toward the target, the longest straight guide groove, and a guide groove that is perpendicular to the guide groove.With the marking tool in Patent Document 1, by positioning the golf ball so that the line drawn by the longest straight guide groove faces toward the cup, it becomes possible to putt while being conscious of the direction of the cup.

[0003] [Patent Document 1] Utility Model Registration No. 3138076 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the putter's eyes are positioned to the side of the body of the putter relative to the line connecting the center of the golf ball to the center of the cup, and on a line that intersects the line perpendicularly and passes through the center of the golf ball. As a result, there is a discrepancy between the line drawn on the golf ball that points toward the cup and the line through which the player sees the cup. This discrepancy can cause the accuracy of putting to be impaired, so the putter should pay more attention to the line perpendicular to the line connecting the center of the golf ball to the center of the cup than to the line connecting the center of the golf ball to the center of the cup, and by hitting the golf ball with the putter face parallel to that line, the accuracy of putting can be improved.

[0005] However, with the marking device of Patent Document 1, the imaginary line pointing toward the target (such as a cup) is the longest, so the putter's attention is drawn to this imaginary line, causing them to neglect the orientation of the putter face and impairing the accuracy of their putting.

[0006] The present invention aims to provide a line marker that allows players to be more aware of the direction of the putter face and improve putting accuracy. [Means for solving the problem]

[0007] (1) A line marker for drawing a line on the surface of a golf ball, a body that can be placed over the golf ball; The main body is formed with a guide portion that serves as a guide for drawing the line and penetrates from the outer surface to the inner surface, The guide portion is a first guide portion that serves as a guide for the line indicating the direction in which the golf ball is to be hit; a second guide portion extending in a direction perpendicular to the first guide portion, The line marker is characterized in that the second guide portion is longer than the first guide portion.

[0008] In the invention of (1), a line marker for drawing a line on the surface of a golf ball has a body that can be placed over the golf ball. The main body is formed with a guide portion that penetrates from the outer surface to the inner surface and serves as a guide for drawing lines. The guide portion includes a first guide portion and a second guide portion. The first guide portion serves as a guide for the line that indicates the direction in which the golf ball is to be hit. The second guide portion extends in a direction perpendicular to the first guide portion. The second guide portion is longer than the first guide portion.

[0009] As a result, a user (e.g., a person putting) places the main body over a golf ball and marks on the golf ball a line drawn using the first guide portion as a guide (hereinafter also referred to as the "first line") and a line drawn using the second guide portion as a guide (hereinafter also referred to as the "second line"). Next, the user places the golf ball with the first and second lines drawn on it. At this time, the user places the golf ball with the first line facing a target (e.g., a cup).

[0010] Next, the user prepares his or her putting posture for the placed golf ball. At this time, the user prepares his or her posture so that his or her line of sight is on the second line. Then, the user strokes the putter face parallel to the second line and hits the golf ball. This causes the golf ball to be hit in a direction perpendicular to the second line (the direction intended by the user).

[0011] Here, when a user focuses on a target (such as a cup) while being conscious of the direction of the first line on the golf ball, the user's line of sight is misaligned with the imaginary line connecting the first line on the golf ball and the target. Therefore, if a stroke is made based on this misaligned line of sight, the putter face will not be able to hit the golf ball at the appropriate angle, and the golf ball will not be hit in the direction the user intended.

[0012] According to the invention of (1), since the second guide portion is longer than the first guide portion, a second line longer than the first line can be attached to the golf ball. Therefore, although the first line is used as a guide when placing the golf ball, the user's attention can be focused on the second line during the stroke. This allows the user to focus on the orientation of the putter face relative to the golf ball at the moment of impact, without being distracted by the line of sight toward the target. Therefore, it becomes possible to be more aware of the direction of the putter face, and the accuracy of putting improves.

[0013] (2) The second guide portion or an extension line of the second guide portion intersects with or is in contact with the first guide portion or an extension line of the first guide portion, The body has a cross-sectional shape formed in an arc shape that follows the surface of the golf ball, The line marker described in (1) is characterized in that, when placed over the golf ball, the guide portion is on the extension of the first guide portion, and is formed at a position 90 degrees from the position where the second guide portion or the extension of the second guide portion intersects or touches the first guide portion or the extension of the first guide portion with respect to the center of the golf ball, and further comprises a third guide portion for drawing an indication of the impact point of the golf ball.

[0014] In the invention (2), the line marker has the second guide portion or an extension of the second guide portion intersecting or contacting with the first guide portion or an extension of the first guide portion. The cross section of the main body is formed into an arc shape that conforms to the surface of the golf ball. The guide portion further includes a third guide portion. The third guide portion, when placed over the golf ball, is an extension of the first guide portion, and is formed at a position 90 degrees from the position where the second guide portion or the extension of the second guide portion intersects or touches the first guide portion or the extension of the first guide portion with respect to the center of the golf ball, and is intended to provide an indication of the impact point of the golf ball.

[0015] According to the invention (2), the user can mark the golf ball with a mark (hereinafter also referred to as an "impact point mark") drawn using the third guide portion as a guide, on the extension of the first line, at a position 90 degrees offset from the position where the second line or the extension of the second line intersects or touches the first line or the extension of the first line. This allows the user to accurately be aware of the position on the golf ball where the face of the putter will hit (impact point mark) and make a stroke.

[0016] (3) The third guide portion is The dimple is formed so as to surround at least a portion of one of the dimples of the golf ball, a first auxiliary portion extending parallel to the second guide portion and aligned with the top of the dimple; The line marker described in (2) is characterized by comprising a second auxiliary portion that is aligned with the side edge in a direction perpendicular to the top of the dimple.

[0017] In the third aspect of the invention, the third guide portion is formed so as to surround at least a portion of one dimple on the golf ball, and includes a first auxiliary portion and a second auxiliary portion. The first auxiliary portion extends parallel to the second guide portion and is aligned with the top of the dimple. The second auxiliary portion is aligned with the side edge portion of the dimple in a direction perpendicular to the top of the dimple.

[0018] The surface of the golf ball is formed with a series of dimples that are recessed toward the center of the golf ball, creating an uneven shape. Therefore, when putting the golf ball, the putter face comes into contact with the raised parts of the golf ball (the areas between the dimples).

[0019] When the putter face comes into contact with the upper or lower end of the convex portion on the extension of the first line, the golf ball will be launched in the direction of the first line (the direction intended by the user). On the other hand, when the putter face comes into contact with the side edge (the side end in the left-right direction) of the convex portion on the extension of the first line, the golf ball is likely to be launched in a direction other than the direction of the first line (the direction intended by the user).

[0020] According to the invention (3), when the user places the main body on the golf ball, he or she focuses on one dimple, aligns the first auxiliary part with the top of the dimple, and aligns the second auxiliary part with the side edge perpendicular to the top of the dimple. In this state, the user marks the first and second lines on the golf ball and marks the impact point using the third auxiliary part as a guide. This allows the impact point mark to be placed on the golf ball at the top end of the convex portion on an extension of the first line. Therefore, by hitting the face of the putter on this impact point mark, the user can hit the golf ball in the direction of the first line (the direction intended by the user). [Effects of the Invention]

[0021] According to the present invention, a line marker can be provided that allows players to be more aware of the direction of the putter face and improve putting accuracy. [Brief explanation of the drawings]

[Figure 6] FIG. 1 is a diagram showing some of the dimples on a golf ball. DETAILED DESCRIPTION OF THE INVENTION

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description, the same components are denoted by the same reference numerals, and the description thereof will be omitted or simplified. FIG. 1 is a perspective view of a line marker according to an embodiment of the present invention attached to a golf ball. FIG. 2 is a top view of a line marker according to an embodiment of the present invention. FIG. 3 is a side view of the line marker according to the embodiment of the present invention as viewed from behind.

[0024] As shown in FIG. 1, the line marker 1 is attached (placed over) a golf ball 100 so that a user can draw a line on the surface of the golf ball 100 using a writing implement, and has a main body 10 that can be placed over the golf ball.

[0025] As shown in FIG. 3, the main body 10 is made of any material such as resin, metal, or wood, and includes a cover portion 11 and an extension portion 12.

[0026] Cover portion 11 is shaped like a hollowed-out hemisphere, with its cross section formed into an arc shape that conforms to the surface of golf ball 100. Cover portion 11 is formed so that the inner diameter of the inner surface is the same as or slightly larger (e.g., 43 to 45 mm) than the outer diameter of golf ball 100 (e.g., 42.67 mm or more).

[0027] The extension portion 12 is formed in a ring shape and extends downward from the lower end of the cover portion 11. The inner diameter of the extension portion 12 is preferably equal to or greater than the inner diameter of the lower end of the cover portion 11. The extension portion 12 may be omitted from the main body 10.

[0028] 1, the main body 10 is formed with a guide portion 20 that penetrates from the outer surface to the inner surface and serves as a guide for the user to draw a line with a writing implement. The guide portion 20 includes a first guide portion 21, a second guide portion 22, and a third guide portion 23.

[0029] The first guide portion 21 serves as a guide for a line indicating the direction in which the golf ball 100 is to be hit (the front-to-rear direction in FIG. 1). As shown in FIG. 2, the first guide portion 21 is a groove that has a predetermined width when viewed from the radial direction of the main body 10 (for example, a width that allows the tip of a writing implement to be inserted, such as 1 to 5 mm), penetrates from the outer surface to the inner surface of the main body 10, and is provided with a straight portion 211 and a direction indicating portion 212.

[0030] Straight portion 211 passes through base point P of main body 10 and is formed in a straight line shape when viewed from above base point P. In this embodiment, the base point of main body 10 is a position on main body 10 that, when main body 10 is placed over golf ball 100, coincides with the position of golf ball 100 facing vertically upward when golf ball 100 is placed on the field.

[0031] Note that the straight portion 211 may be configured, for example, by a plurality of dot-shaped or straight-line grooves, as long as it is arranged on a line passing through the base point P of the main body 10. That is, as shown in FIG. 1 or 2, the straight portion 211 may be configured such that the straight portion 211 itself passes through the base point P of the main body 10, or, for example, if the straight portion 211 is configured by a plurality of dot-shaped or straight-line grooves, the extension line L of these center lines (a line passing through the center of the straight portion 211 in the width direction and extending in the direction in which the straight portion 211 extends) extending on the outer surface of the main body 10 may pass through the base point P of the main body 10. Furthermore, in the example shown in FIG. 1 or 2, the straight portion 211 is formed in a manner that passes through the base point P of the main body 10, but is not limited thereto, and the straight portion 211 may extend with the base point P as a base point.

[0032] The direction indicating portion 212 is formed on one end side of the straight portion 211 and extends obliquely with respect to the straight portion 211 from one end of the straight portion 211 as an apex to the other end side of the straight portion 211 .

[0033] With this configuration, the first guide portion 21 is formed in the shape of an arrow that passes through the base point P of the main body 10. Note that the first guide portion 21 may be formed in the shape of a straight line that passes through the vertex of the main body 10, without the direction indicating portion 212.

[0034] The second guide portion 22 passes through the base point P of the main body 10, and is formed in a linear shape when viewed from above the base point P, and extends in a direction perpendicular to the first guide portion 21.

[0035] The second guide portion 22 is a groove that has a predetermined width when viewed from the radial direction of the main body 10 (for example, a width that allows the tip of a writing instrument to be inserted, such as 1 to 5 mm), penetrates from the outer surface to the inner surface of the main body 10, and is formed with a length when viewed from above the base point P of the main body 10 that is longer than that of the first guide portion 21 (straight portion 211).

[0036] Note that the second guide portion 22 may be configured, for example, by a plurality of dot-shaped or linear grooves, as long as it is disposed on a line passing through the base point P of the main body 10. That is, as shown in Fig. 1 or 2, the second guide portion 22 may be configured in a form in which the second guide portion 22 itself passes through the base point P of the main body 10, or, for example, in a case in which the second guide portion 22 is configured by a plurality of dot-shaped or linear grooves, the extension line of these center lines (lines passing through the center of the second guide portion 22 in the width direction and extending in the extension direction of the second guide portion 22) extending on the outer surface of the main body 10 may pass through the base point P of the main body 10.

[0037] In this way, the center line of the second guide portion 22 or an extension line of the second guide portion 22 intersects with or is tangent to the center line of the first guide portion 21 (straight portion 211) or the extension line L of the first guide portion 21 (straight portion 211) at the base point P. That is, in this embodiment, the base point P of the main body 10 is the point where the center line of the second guide portion 22 or an extension line of the second guide portion 22 intersects with or is tangent to the center line of the first guide portion 21 (straight portion 211) or the extension line L of the first guide portion 21 (straight portion 211).

[0038] 1, third guide portion 23 is formed on extension line L of first guide portion 21 (straight portion 211) at a position 90 degrees from base point P with respect to center C of golf ball 100 when placed over golf ball 100, and serves to indicate the golf ball's impact point. In this embodiment, third guide portion 23 is formed by a notch formed in the side edge of main body 10, but is not limited to this and may be formed by a hole or groove penetrating main body 10.

[0039] As shown in Figure 3, the third guide portion 23 is formed to surround at least a portion of one of the dimples 110 on the golf ball, and serves as a guide for the user to draw a line using a writing instrument, and also functions as a position adjustment portion that adjusts the position of the line marker 1 and the golf ball 100 when the user places the line marker 1 on the golf ball 100.

[0040] The first auxiliary portion 231 extends parallel to the second guide portion 22 and is aligned with the apex 110 a of the dimple 110 . The second auxiliary portion 232 is aligned with the side edge 110b in a direction perpendicular to the apex 110a of the dimple 110. In this embodiment, the second auxiliary portion 232 is provided on each end of the first auxiliary portion 231, but the second auxiliary portion 232 may be provided on only one of the first auxiliary portions 231.

[0041] FIG. 4 is a diagram illustrating a golf ball on which lines are marked by a line marker according to an embodiment of the present invention. The user first places the line marker 1 on the golf ball 100, focuses on one of the dimples 110 on the golf ball 100, and aligns the top 110a of the dimple 110 with the first auxiliary portion 231 of the third guide portion 23, and aligns the side edge 110b of the dimple 110 with the second auxiliary portion 232. This results in an appropriate positional relationship between the golf ball 100 and the line marker 1, as shown in FIG.

[0042] In this state, the user uses a writing implement to draw a first line RL1 on the surface of the golf ball 100, using the first guide portion 21 as a guide to indicate the direction in which the golf ball 100 will be hit, and using the second guide portion 22 as a guide to draw a second line RL2 to make the user aware of the direction of the putter face when making a stroke, and using the first auxiliary portion 231 of the third guide portion 23 as a guide to draw a third line RL3 to indicate the position (impact point marker) where the putter face will hit the golf ball 100.

[0043] 4, a first line RL1 and a second line RL2 that is perpendicular to and longer than the first line RL1 are marked on the surface of golf ball 100. In addition, a third line RL3 is marked on the surface of golf ball 100 on an extension of first line RL1, at a position 90 degrees from the intersection of first line RL1 and second line RL2 with respect to the center C of golf ball 100.

[0044] FIG. 5 is a diagram illustrating the line of sight of a user when putting a golf ball on which a line has been marked by a line marker according to an embodiment of the present invention. When placing the lined golf ball 100, the user points the first line RL1 toward a target T (for example, a cup) and places the ball with the intersection of the first line RL1 and the second line RL2 pointing vertically upward.

[0045] When putting, the user turns their body in the direction in which the second line RL2 extends so that the center of their body is in the direction in which the second line RL2 extends, and strokes toward the third line RL3, being conscious of keeping the face surface f of the putter P parallel to the second line RL2.

[0046] Here, the user's line of sight when putting will be described. 5, the line of sight S1 directed toward the target T (e.g., a cup) is deviated (angled) from the imaginary line connecting the first line RL1 marked on the golf ball 100 and the target T. Therefore, if a stroke is made based on this deviated line of sight S1, the face f of the putter P cannot hit the golf ball 100 at an appropriate angle, and the golf ball 100 will not be hit in the direction intended by the user.

[0047] When putting, the user does not pay attention to the first line RL1, but strokes the face f of the putter P parallel to the second line RL2, thereby hitting the golf ball 100 in the intended direction.

[0048] FIG. 6 is a diagram showing some of the dimples on a golf ball. A plurality of dimples 110 are arranged at predetermined intervals on the surface of golf ball 100. Therefore, if the center of each dimple 110 is considered to be a recess, a protrusion (the apex of each dimple 110 (the portion farthest from the center of golf ball 100)) is formed between adjacent dimples 110. This protrusion is the portion that comes into contact with the face f of putter P (see FIG. 5) when putting.

[0049] This convex portion has a top portion 110a parallel to the grounded surface G of golf ball 100 and a side portion 110b perpendicular to the grounded surface G. When the golf ball 100 is putted, and the face f of the putter P comes into contact with the apex 110a, the golf ball 100 is launched in the same direction as the stroke of the putter P. On the other hand, when the golf ball 100 is putted, if the face f of the putter P comes into contact with the side portion 110b, there is a high possibility that the golf ball 100 will be hit in a direction different from the direction in which the putter P was stroked.

[0050] According to the line marker 1 of the present embodiment, the third line RL3 can be drawn at or near the apex 110a by aligning one dimple 110 of the golf ball 100 with the third guide portion 23 and then drawing the third line RL3 using the first auxiliary portion 231 of the third guide portion 23 as a guide. Furthermore, since the first line RL1 and the second line RL2 are drawn after aligning one dimple 110 of the golf ball 100 with the third guide portion 23, when placing the golf ball 100 with these lines, if the first line RL1 is directed toward the target T (e.g., a cup) and the intersection of the first line RL1 and the second line RL2 is directed vertically upward, the third line RL3 will inevitably be positioned at the appropriate impact point (a position 90 degrees from the intersection of the first line RL1 and the second line RL2).

[0051] According to such a line marker 1, the second guide portion 22 is longer than the first guide portion 21, and therefore the second line RL2, which is longer than the first line RL1, can be applied to the golf ball 100. Therefore, although the first line RL1 serves as a guide when placing the golf ball 100, the user's attention can be focused on the second line RL2 during the stroke. This allows the user to focus on the orientation of the face f of the putter P relative to the golf ball 100 at the moment of impact, without being distracted by the line of sight toward the target. Therefore, it becomes possible to be more aware of the direction of the putter face, and the accuracy of putting improves.

[0052] Furthermore, with the line marker 1, the user can mark the golf ball 100 with a third line RL3, which serves as a mark (hereinafter also referred to as an "impact point mark") that is drawn using the third guide portion 23 as a guide, on the extension of the first line RL1, at a position that is 90 degrees offset from the position where the second line RL2 or the extension of the second line RL2 intersects or touches the first line RL1 or the extension of the first line RL1. This allows the user to accurately be aware of the position on the golf ball where the face of the putter will hit (impact point mark) and make a stroke.

[0053] Furthermore, with the line marker 1, when the user places the main body 10 on the golf ball 100, he or she focuses on one dimple 110, aligns the first auxiliary portion 231 with the peak 110a of the focused dimple 110, and aligns the second auxiliary portion 232 with the side edge 110b in a direction perpendicular to the peak 110a of the dimple 110. In this state, the user marks the first line RL1 and the second line RL2 on the golf ball 100, and then marks the third line RL3, which serves as an impact point marker, using the third guide portion 23 as a guide. This allows the third line RL3 to be attached to the apex 110a of the golf ball 100, which is an extension of the first line RL1. Therefore, by hitting the face f of the putter P on the third line RL3, the user can hit the golf ball 100 in the direction of the first line RL1 (the direction intended by the user).

[0054] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. [Explanation of symbols]
