Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a putter used in green when playing golf, and in particular to a putter with markings on the face surface on which a ball is hit.

  In the past, golf putters are known to be marked as an index when hitting a ball. The marking is provided on the putter's head to help put the ball after hitting a ball on the line captured by the player (the line captured when the ball rolls to the cup and cups in). Generally, for example, as disclosed in Patent Document 1, the top side (upper surface of the head) of the head is provided with a line perpendicular to the face surface, or such a line is provided on the back side or the like. What has been known. Alternatively, if the putter is not given such markings, the player looks at the directionality by looking at the upper and lower edges (edges extending in the toe-heel direction) defining the face portion or the grooves provided on the face surface. It is being done. That is, the marking or the upper and lower edges or grooves as described above is important for the player to address and put a ball on a line as expected.

  Although it is conceivable to provide marking on the face surface where the hitting point and the position of the ball are closest to each other, generally the loft angle of the face surface of the putter is small (10 ° or less, and usually As described above, it is generally provided on the upper surface of the head or the like because it is difficult to see when addressing.

Unexamined-Japanese-Patent No. 2006-326216

  As described above, the marking provided on the head portion of the putter is an indicator for placing the putted ball on the line. With regard to such markings, it is considered to be important to make the player aware of the position and direction of the ball at the moment of hitting, so it is considered preferable to provide them on the face surface where hitting is made. As described above, since the loft angle of the putter is small, it is difficult to make the player visually recognize the marking even on the face surface.

  The present invention has been made based on the above-described problems, and an object of the present invention is to provide a golf putter that makes it easy for a player to view markings serving as a guide for the directionality of hitting balls attached to a face surface.

In order to solve the problems described above, the golf putter according to the present invention includes a head having a face surface height of 20 to 30 mm, and the face surface includes a sole side face surface and a top side face. Provided that the loft angle of the sole side face surface is α1 and the loft angle of the top side face surface is α2, α1 <α2 and 1 ° ≦ α1 , and the height of the sole side face surface is The length is 15 mm or more, and a marking is provided near the hitting position of the sole side face surface.

  According to the golf putter having the above-described structure, the player can address by forming the face surface with a plurality of faces and forming the loft angle α2 of the top side face surface larger than the loft angle α1 of the sole side face surface. At the time of visualizing, the face surface on the top side is not obstructed, and the sole side face is easy to visually recognize. Therefore, the ball is hit while visually recognizing the marking attached near the hitting position on the sole side face. can do. That is, since the player can be made aware of the position of the ball and the proper directionality of the head by the marking at the moment of hitting, the directivity of the hit ball can be improved.

  In the above configuration, the hitting position means the hitting position (sweet spot) which is an ideal hitting position in the putter, and the marking is in the vicinity (sweet spot) to make the player aware of such a position. Above). Further, in the above-described configuration, the sole side face surface and the top side face surface may include not only a flat surface but also a slightly curved surface. Furthermore, with respect to the loft angle of each face surface, it is preferable that 1 ° ≦ α1 ≦ 5 ° and 5 ° ≦ α2 ≦ 10 ° so that the sole side face surface is easily visible at the time of addressing.

  According to the golf putter of the present invention, the marking serving as a pointer for the directionality of the striking ball attached to the face surface can be easily viewed by the player, and the directionality of the striking ball can be improved.

It is a figure which shows 2nd Example of this invention, and is a side view of a head part. The enlarged view which looked at the marking attached to the face of FIG. 8 from the front.

  1 to 5 are views showing a first embodiment of a golf putter (hereinafter referred to as putter) according to the present invention, FIG. 1 is a front view, and FIG. 2 is a golf putter shown in FIG. 3 is a perspective view of the head portion of the golf putter shown in FIG. 1, FIG. 4 is a plan view of the head portion of the golf putter shown in FIG. 1, and FIG. 5 is the face shown in FIG. Is an enlarged view from the front of the marking attached to the.

  The putter 1 includes a shaft 5 to which a grip 5 a is attached on the base end side, and a head 10 attached to the tip of the shaft 5. The shaft 5 is made of metal or fiber reinforced resin, and the head 10 is integrally formed with a metal material such as stainless alloy, aluminum alloy, iron or the like so as to have a predetermined shape by forging or casting, for example. Is made up of In this case, the head may have a single structure or a structure in which a plurality of members are combined.

  The head main body 10A constituting the head 10 is provided with a face surface (pasting surface) 11 on which a ball is hit, and the face surface may be an insert structure of a material different from that of the head main body. Other than that, the top part 12, the sole part 13, and the back part 14 are provided. The head body 10A of the present embodiment is formed on a flat surface 12a in which the top portion 12 is rectangular in plan view, and the sole portion 13 is rectangular in plan view having a longer length in the face-back direction than that. Is formed on the flat surface 13a. In this case, the sole portion 13 may be curved along the toe-heel direction so that the toe side and the heel side rise. The back portion 14 has a step portion, and includes a rectangular flat surface 14 a parallel to the flat surfaces constituting the top portion 12 and the sole portion 13.

  In the head main body 10A as described above, the ridges in the face-back direction of the top portion 12 (face-side ridges 12A and back-side ridges 12B) are orthogonal to the head traveling direction at the time of swinging, thus providing directionality. It becomes possible to set it as a standard. In addition, the face side ridgeline 13A of the sole portion 13 is also in a state of being easily visible due to the relationship of loft angles α1 and α2, which will be described later. Furthermore, since the ridgeline 14A at the rear end of the back portion 14 is also orthogonal to the traveling direction of the head at the time of swinging, it becomes possible to use it as a reference for achieving directivity.

  The present invention is characterized in the configuration of the face surface of the head main body, and the configuration of the exception is not limited. For example, the shape of the head body (the shapes of the top portion, the sole portion, and the back portion) and the method of attaching the shaft to the head body are not limited. Further, as shown in FIGS. 3 and 4, the head main body 10A of the present embodiment includes the toe portion 15 and the heel portion 16 extending in the vertical direction from the sole portion, but these are integrated with other portions. It may be formed continuously in a flush manner. Of course, the ridge line 12C on the toe side and the ridge line 12D on the heel side in the top portion and the back portion can also be set as a reference for providing directionality by being configured to coincide with the traveling direction of the head. It becomes possible.

  The head body is preferably formed so that the height H of the face surface 11 is 20 to 30 mm so that the player does not feel discomfort, and the face surface 11 includes the sole side face surface 11A and the top side. A face 11B is provided. Each of the face surfaces 11A and 11B is formed so that the loft angle (the angle of the face surface with respect to the perpendicular when the perpendicular is drawn on the horizontal surface P as shown in FIG. 2) is different. And .alpha.2, they are formed such that .alpha.1 <.alpha.2. That is, the face surface 11 includes a plurality of surfaces, and a ridgeline 11C is formed at the boundary between the sole side face surface 11A and the top side face surface 11B due to a change in loft angle.

  In the above configuration, the head main body 10A is formed such that the surface on which the ball is actually hit is the sole side face surface 11A, and the sweet spot of the head main body (a position where the head main body is difficult to shake when hitting) A position where a vertical line is drawn from the center of gravity position of the head main body to the face surface; also referred to as a hitting position) S exists below the ridgeline 11C. Here, the height H1 of the sole side face surface 11A is formed to be 15 mm or more. In this case, the height H1 of 20 mm or more means that the golf ball B has a diameter of 1.68 inches (42.672 mm) or more on the rule, and the ball hitting point (ball The height of the position P1 closest to the center surface C from the center C is 21.336 mm, which is its radius. In practice, the golf ball B sinks slightly by the green grass, and the player usually swings (patters) the head main body by floating about 1 to 5 mm from the ground contact surface, so the sole side face surface If the height (length in the vertical direction) H1 of 11A is secured at least 15 mm, the hitting point P1 of the ball can be hit at a position lower than the ridgeline 11C at the time of hitting.

  If the height H1 of the sole side face 11A is set to less than 15 mm, the player does not preferably hit the sole side face 11A without swinging with the head body floating to some extent. Further, when the height (length in the vertical direction) of the top side face surface 11B is H2, it is preferable to form H1 H H2 so as to make the hitting face wider for the player.

A marking 20 is attached in the vicinity of the sweet spot (ball hitting position) S of the sole side face surface 11A.
The marking 20 according to the present embodiment includes one horizontal line 21 provided to cross the sweet spot S and two vertical lines 23 a and 23 b extending vertically downward at both ends of the horizontal line 21. To allow the player to recognize the area within this range as the target position (sweet area) to be hit.

  The lateral lines 21 described above are provided so that the lengths on both sides of the sweet spot S are equal, and the length W1 is approximately 10 to 30 mm. That is, when the hitting point P1 of the ball is within this range, the toe side and the heel side of the head body do not shake at the time of hitting, and it is possible to launch the ball accurately. In this case, the length W1 in the lateral direction is preferably 10 mm or more in order to improve visibility.

  Further, the two vertical direction lines 23a and 23b described above are provided on both sides of the sweet spot S so as to be symmetrical. That is, since the horizontal lines 21 are formed so that the lengths on both sides are equal with the sweet spot S at the center as described above, the two vertical lines 23 a and 23 b are respectively set to the horizontal lines 21. By hanging in a direction perpendicular to the direction perpendicular to the sweet spot S (a virtual center line X passing through this point), a vertical marking axisymmetrically attached is obtained. In this case, the longitudinal lines 23a and 23b are preferably attached without straddling the ridgeline 11C (do not interfere with the top face surface), and the height H3 of the longitudinal direction also indicates the height of the sole face surface 11A described above. It is preferable to make it less than H1.

  According to the putter 1 having the above-described configuration, the loft angle α2 of the top side face surface 11B is formed larger than the loft angle α1 of the sole side face surface 11A. Therefore, when the player addresses, the top side face surface There is no hindrance to 11B, and the sole side face 11A is easily visible. For this reason, as shown in FIG. 4, the above-mentioned marking 20 attached to the sole side face surface 11A can be visually recognized at the time of the address, thereby being attached near the hitting position of the sole side face surface 11A. The ball can be hit while visually recognizing the marking 20. That is, since the player can be aware of the position of the ball and the proper directionality of the head by marking (the proper directionality to the hitting ball) at the moment of hitting, the directionality of the hit ball is improved. It can be done.

  Further, as described above, since the longitudinal lines 23a and 23b are attached so as to be line symmetrical with respect to the sweet spot S, it is possible to always position the player's viewpoint at an ideal position. . Specifically, as shown in FIG. 6A, when addressing with the putter 1, assuming that the position where the ball is viewed from directly above (appropriate position) is E1, and the position not directly above is E2, it is appropriate. When the marking applied to the sole side face surface 11A is visually recognized at the proper position E1, as shown in FIG. 6B, the longitudinal lines 23a and 23b appear to extend in the direction orthogonal to the transverse line 21. However, when viewed at a position E2 which is not directly above, as shown in FIG. 6C, the vertical lines 23a and 23b are directed obliquely with respect to the horizontal line 21 (the lower ends of the vertical lines 23a and 23b are Since it looks as if it extends in the direction of the arrow direction), it is possible to make the player aware of an appropriate eye point at the time of addressing.

  The longitudinal lines 23 a and 23 b described above may not be orthogonal to the horizontal line 21. For example, as shown in FIG. 7A, the lines of symmetry (C-shaped lines of symmetry) 23a 'and 23b' may be set so as to move away from each other as they move toward the sole side. According to such a symmetry line, when the ball is viewed at a position not right above, as shown in FIG. 7B, one longitudinal line 23a 'and the other longitudinal line 23b' do not appear symmetrical ((b) Since it looks like an irregular shape), it is possible to make the player aware of an appropriate eye point at the time of addressing, as described above. The lines of symmetry 23a 'and 23b' may be attached in the form of an inverted V shape.

  About the marking 20 given to the sole side face surface 11A mentioned above, it is possible to change the how to give it variously. For example, only the horizontal direction line 21 shown in FIG. 3 may be attached. Since the width of the sweet area in the toe-heel direction can be visually recognized even by such a lateral line 21 alone, the head can be aligned in the traveling direction because it extends in the direction orthogonal to the traveling direction of the head body. It becomes. Further, as shown in FIG. 4, upper and lower ridge lines (the face side ridge lines 12A and 13A) defining the face surface 11 and a ridge line 11C which is a boundary between the sole side face surface 11A and the top side face surface 11B. Since it can be viewed in parallel with the lateral direction line 21, it becomes easy to align the traveling direction of the head.

Further, as shown in FIGS. 8 and 9, it is preferable that a plurality of (21a, 21b, 21c) lines be provided at regular intervals in the vertical direction for the horizontal direction line.
By providing a plurality of such marks, when the loft angle α1 is present in the sole-side face surface 11A, when viewed from above, these are single markings (markings that become somewhat wider in the head traveling direction) Can be visually recognized, and the traveling direction of the head can be more easily aligned.

  In addition, the marking 20 may have only longitudinal lines, and may have one or more longitudinal lines. In this case, if only one is provided, it is possible to recognize a specific hitting position by passing the sweet spot S (coincident with the virtual center line). That is, it is possible to recognize the hitting position with awareness of one longitudinal line while aligning the advancing direction by the ridge line extending in the toe-heel direction described above. Also, if there are two or more longitudinal lines, in the case of an even number, as described above, it may be provided at symmetrical positions with respect to the virtual center line, and in the case of an odd number, one of the virtual center lines The position may be given, and the others may be given at positions symmetrical with respect to the virtual center line.

  As described above, with regard to the marking provided on the sole side face surface, the hitting position can be recognized only by the longitudinal direction line, and by providing a plurality of marks, the sweet area to be the target position of hitting can be recognized. It becomes possible.

  The marking 20 only needs to be provided so that the player who has made the address can visually recognize it. For example, the marking 20 can be formed in a protruding shape or in a recessed shape (groove). In addition, when coloring (coloring) by printing or painting, or when finishing the face surface, masking may be performed to perform surface finishing (grinding, cutting). In the case of adding a color as a marking, it is preferable to add a color with high brightness (white-based color), a red-based color, or the like so that the player can visually recognize at the time of addressing. Moreover, when a protrusion and a groove are formed as marking, the structure which gives color to these parts may be sufficient.

  The marking shown in FIG. 8 and FIG. 9 is composed of a plurality of lateral lines 21a, 21b and 21c, and the lateral lines 21a passing through the sweet spot are grooves. When coloring such a groove, at least the four inner side walls defining the groove and the inner side wall 21a1 on the sole side that is visible when viewed from at least the upper side of the bottom wall Is preferable.

  Moreover, when forming a groove as marking, if the depth is 0.2 mm or more, it is possible to make it difficult to lose color when color is applied. Moreover, about the width | variety of the groove | channel used as the marking, it is preferable to form in about 0.3-2.0 mm in consideration of the ease of processing, etc.

  In the lateral lines shown in FIGS. 8 and 9, only the lateral line 21a passing through the sweet spot is formed as a groove, but the other lateral lines 21b and 21c may also be formed as a groove. As described above, when a color is applied to the inside of the marking as a groove structure, the color is less likely to disappear, so that the marking can be stably maintained for a long time. The three horizontal lines may be line symmetrical with respect to the imaginary center line X, and the lengths of the three lines may not be the same.

  The marking 20 described above is formed on the sole side face surface 11A having a small loft angle α1, and the loft on the upper side face (top side face surface 11B) of the face surface so that the marking 20 is easily visible. The angle α2 is increased. In this case, it is preferable to set the loft angle of the face surface configured by the composite surface of the present invention to be 10 ° or less so as to avoid a sense of discomfort with a general putter, and a sole For the loft α1 of the side face surface, 1 ° ≦ α1 ≦ 5 °, and for the top side loft angle α2, set the range of 5 ° ≦ α2 ≦ 10 ° so that the sole side face surface is easily visible. Is preferable. Alternatively, the loft angle α1 may be set to 5 ° or more and 8 ° or less. When the loft angle α1 is thus increased, the loft angle α2 is set to be larger than the loft angle α1 and 10 ° or less You should do it.

  Further, in the above-described configuration, the sole side face surface and the top side face surface may include not only a flat surface but also a slightly curved surface, and further include a flat surface having another loft angle. It may be. Further, the marking may be formed on the sole side face surface, and a part of the marking may be provided on the top side face surface. For example, it may be provided at the lower end of the top face 11B (which may cross the ridgeline 11C).

  The embodiment of the present invention has been described above. However, the present invention is characterized by the structure of the face surface of the head body of the putter, and the other configurations can be configured in various modes.
