[Problems to be solved by the invention]
However, even if a line is provided on the upper surface of the head as in the above-described example, it is difficult to set the orientation of the face with respect to the ball with high accuracy at the time of addressing using only the line. In particular, in situations where there is a lot of pressure, such as when you really want to put and put in a putter golf club, it is difficult to set the orientation of the face with high accuracy at the time of addressing, and it is easy to make a putt mistake Become.
[0010]
Further, when the head of the putter golf club itself is T-shaped, there is no portion that serves as an index for setting the face orientation at the time of addressing. In addition, there is a golf club head provided with an index having a top edge portion and a back side portion extending in the back direction from the center portion of the top edge portion, but the width of the top edge portion and the back side portion is the same. Sometimes it is difficult to see as an index for setting the face orientation. For this reason, it is necessary to set the face orientation based on the shape of the entire head, and the reference for setting the face orientation with respect to the ball at the time of addressing becomes too large, making it difficult to recognize the reference. Therefore, it becomes difficult to discriminate subtle changes in the orientation of the face, and it is easy for a mistake to occur.
[0011]
Accordingly, an object of the present invention is to provide a golf club head capable of setting the orientation of the face with high accuracy at the time of addressing, and a golf club provided with the head.
[0012]
[Means for Solving the Problems]
In one aspect, a golf club head according to the present invention includes a head body including a face portion, a toe portion, a heel portion, and a back portion, and a face side portion provided on the upper surface of the head body and extending along the face portion. And an indicator portion including a back side portion extending from the face side portion toward the back portion, and a width in the toe / heel direction of the back side portion of the indicator portion is defined as a width in the face / back direction of the face side portion. Make it wider. Here, the face-back direction is a direction from the face part of the head body toward the back part, and the toe-heel direction is a direction from the toe part of the head body toward the heel part.
[0013]
Thus, since the indicator portion includes the face side portion and the back side portion, the orientation of the face can be adjusted at the time of addressing using both of them. At this time, by making the width in the toe / heel direction of the back side portion of the index portion wider than the width in the face / back direction of the face side portion, the back side portion is emphasized in the index portion. It becomes easy to recognize as an index for setting the orientation of the face at the time of addressing.
[0014]
In another aspect, the golf club head according to the present invention includes a head body including a face portion, a toe portion, a heel portion, and a back portion, and a face side portion that is provided on the upper surface of the head body and extends along the face portion. And an indicator portion having a substantially T shape composed of a back side portion extending from the center portion of the face side portion toward the back portion, and the width of the indicator portion on the back side portion in the toe-heel direction. The width of the face side portion is wider than the width in the face-back direction.
[0015]
As described above, the indicator portion has a substantially T-shape including the face-side portion and the back-side portion, so that the orientation of the face is adjusted at the time of addressing using both the face-side portion and the back-side portion in the T-shape. can do. Further, by making the width of the back side portion of the T-shaped index portion in the toe / heel direction wider than the width of the face side portion in the face / back direction, the impact on the back portion of the index portion is emphasized. It becomes a T shape with a certain shape, and is easily recognized as an index for setting the orientation of the face at the time of addressing.
[0016]
The indicator portion is preferably provided in a convex shape. Further, the indicator portion may be made of a material different from the material of the head body, and the indicator portion may be attached to the upper surface of the head body. The face side portion preferably extends in the vicinity of the face portion from the vicinity of the toe portion to the vicinity of the heel portion, and the back side portion preferably extends to a portion on the side farthest from the face portion on the upper surface of the head body. Reach.
[0017]
It is preferable that at least one of hue, lightness, and saturation on the upper surface of the head main body is different from the hue, lightness, and saturation on the upper surface of the indicator portion.
[0018]
A hitting direction indicating line for instructing the hitting direction may be provided on the upper surface of the indicator part, or a central display part for displaying the central part in the longitudinal direction of the face side portion.
[0019]
The width of the back side portion in the toe / heel direction is reduced as it is away from the face portion, or the width of the face side portion in the face / back direction is maximized in the center portion of the face side portion in the toe / heel direction, It is preferable to make it narrower as it approaches the toe part and the heel part.
[0020]
A golf club according to the present invention includes the above-described golf club head. Therefore, it is possible to set the direction of the face at the time of addressing with high accuracy, and to obtain a golf club capable of smooth swing.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, golf club heads and golf clubs according to embodiments of the present invention will be described. The present embodiment can be applied to any of a wood golf club, an iron golf club, and a putter golf club, but is particularly useful for a putter golf club.
[0022]
The golf club in the present embodiment includes a golf club head, a shaft, and a grip which will be described later. The golf club head includes a head main body and an indicator portion on the upper surface of the head main body. Well-known shafts and grips can be used.
[0023]
The head body is made of a composite material of a metal other than a metal, such as a metal such as stainless steel or a titanium alloy, or a resin. In the case of a wood golf club, the head body typically has a metal outer shell structure, and includes a face portion, a crown portion, a sole portion, a toe portion, a heel portion, and a back portion. In the case of an iron golf club, the head body has, for example, a metal outer shell structure or a cavity back structure, and includes a face portion, a sole portion, a toe portion, a heel portion, and a back portion. In the case of a putter golf club, the head main body typically has a solid metal structure, and includes a face portion, a toe portion, a heel portion, and a back portion.
[0024]
The indicator portion includes a face side portion extending along the face portion and a back side portion extending from the face side portion toward the back portion. Therefore, the orientation of the face can be adjusted at the time of addressing using both the face side portion and the back side portion. Here, “address” refers to a posture in which the golf club is set on the back side of the ball without contacting the ball in order to hit the golf ball.
[0025]
The indicator portion preferably has a substantially T-shape configured by a face side portion and a back side portion extending from the center portion of the face side portion toward the back portion. In this way, the indicator portion has a substantially T-shape, so that the indicator portion can be conspicuous and the indicator portion can be clearly recognized at the time of addressing. Therefore, even under a very high pressure situation such as when it is absolutely desired to cup-in, attention can be directed to the indicator portion, and the orientation of the face can be adjusted with high accuracy at the time of addressing.
[0026]
The face side portion is preferably arranged in the vicinity of the top edge, which is the upper edge of the face portion. Accordingly, the face side portion can be easily recognized at the time of addressing, and the orientation of the face can be adjusted with high accuracy.
[0027]
In addition, by extending the back side portion in a direction (rear side) substantially perpendicular to the face surface, an ideal stroke can be realized by stroking in a direction along the back side portion. In the case of a club head, it is possible to realize a head that is extremely excellent in the direction of hitting.
[0028]
Furthermore, it becomes easy to swing smoothly by extending the back side portion backward. As a result, it is easy to perform the desired pad swing, the ball can be hit firmly, and miss shots can be reduced. In addition, since the degree of freedom in design can be expanded, it is possible to produce a head with excellent design.
[0029]
The above effect is considered to be particularly remarkable when the index portion has a size of a certain level or more. For example, the length of the face side portion of the index portion is set to about 50% or more and 100% or less of the length of the face portion in the toe / heel direction, which is the direction from the toe portion toward the heel portion. It is conceivable that the length is about 50% to 100% of the length of the head body in the face-back direction, which is the direction from the face part toward the back part.
[0030]
Also, when the face side part extends from the vicinity of the face part (near the top edge part) to the vicinity of the heel part, and the back side part reaches the part of the top surface of the head body that is farthest from the face part. In addition, the above effect is considered to be remarkable.
[0031]
The indicator portion may be provided in a concave shape on the upper surface of the head body, but is preferably provided in a convex shape. For example, both the face side portion and the back side portion are made of a solid member such as a plate-like member having a certain thickness, or a hollow member, and the face side portion and the back side portion are made of convex portions having a relatively wide width. It is possible to do. As a result, the index part can be effectively conspicuous, and the index part can be recognized more clearly at the time of addressing.
[0032]
The indicator portion can be made of the same material as that of the head body, but may be made of a material different from that of the head body. When the indicator portion is made of the same material as the head main body, for example, a convex portion can be provided when the head main body is formed by casting or forging, or the head main body can be machined to provide a convex portion. .
[0033]
In a case where the index portion is made of a material different from that of the head body, as a preferred example, it is conceivable that the index portion is made of resin and the head body is made of metal. As the resin, for example, acrylic resin, polycarbonate resin, vinyl chloride resin, acrylonitrile / butadiene / styrene copolymer (ABS) resin, polypropylene resin, urethane resin, or an elastomer thereof can be used. When the indicator portion is attached to the head body, the indicator portion may be joined to the upper surface of the head body using, for example, a double-sided tape or an adhesive. Thereby, the indicator portion can be brought into a state of being raised on the upper surface of the head body, and the indicator portion can be effectively made conspicuous.
[0034]
It is preferable that at least one of the hue, brightness, saturation, and surface roughness on the upper surface of the head main body is different from the hue, brightness, saturation, and surface roughness on the upper surface of the indicator section. For example, the head main body upper surface other than the index part is processed to suppress the lightness more than the index part, or the surface roughness of the head main body upper surface and the index part upper surface is made different to make the finishing state different. It is possible.
[0035]
As processing for suppressing the lightness, for example, a paint having a lightness and low saturation such as black may be applied, or the upper surface of the head main body may be coated with rubber or the like. As processing for making the finished state different, for example, it is conceivable to make the upper surface of the head main body a matte surface such as a satin surface or a matte surface by plating.
[0036]
Also, the color of the head body upper surface and the indicator top surface are different, the degree of vividness of the colors attached to the head body upper surface and the indicator top surface is different, or the patterns, characters, and symbols that are different on the head body top surface and the indicator top surface. It is also possible to add such as.
[0037]
By differentiating at least one of the hue, brightness, saturation, and surface roughness of the upper surface of the head body and the upper surface of the indicator portion as described above, for example, the contrast between the head body and the indicator portion can be enhanced, The indicator part can be made more conspicuous.
[0038]
Also, the width of the back side portion in the toe / heel direction (width in the direction from the toe portion toward the heel portion) is larger than the width in the face / back direction of the face side portion (width in the direction toward the back portion from the face portion). It is preferable to make it wide.
[0039]
By making the width of the back side portion in the toe / heel direction wider than the width of the face side portion in the face / back direction as described above, the indicator portion has an impact shape, and even if it is in tension at the time of addressing, the indicator You can focus on the department. Thereby, even when it is easy to become a tension | tensile_strength state, for example at the time of putting, it can stroke smoothly.
[0040]
Further, it is possible to suppress only the face side portion, that is, the top edge portion of the head main body, from being emphasized, and as a result, it is possible to avoid difficulty in recognizing directionality. The width of the back side portion in the toe / heel direction is appropriately about the diameter of the golf ball.
[0041]
The width of the back side portion in the toe / heel direction is made wider than the width of the face side portion in the face / back direction as a whole, and straight from the face side portion located above the sweet spot of the face surface to be orthogonal to the face surface. It is also conceivable to extend the back side portion backward. In the case of such a shape, it becomes easy to concentrate the consciousness on the back side portion of the index portion at the time of addressing, and the hitting direction becomes easier to recognize.
[0042]
It is also conceivable that the width in the face / back direction at the center of the face side portion is wider than the width in the face / back direction at the end portion in the toe / heel direction of the face side portion. For example, the width in the face-back direction of the face side portion may be the largest in the center portion in the toe / heel direction in the face side portion, and may be narrowed as approaching the toe portion and the heel portion.
[0043]
Also, the width in the toe / heel direction of the back side portion at the connecting portion with the face side portion is wider than the width in the toe / heel direction of the rear end portion of the back side portion, and the rear edge of the face side portion The toe side edge of the back side portion and the heel side edge of the back side portion may be configured with smooth curves. At this time, it is preferable that the width of the back side portion in the toe-heel direction is narrowed as the distance from the face portion increases (rearward).
[0044]
As described above, by making the width in the toe / heel direction of the back side portion at the connection portion with the face side portion wider than the width in the toe / heel direction of the rear end portion of the back side portion, Since the back side is felt wide and heavy, it is possible to avoid a situation in which a feeling of smooth swing-out is not obtained, and as a result, it becomes unstable at the time of addressing.
[0045]
A hitting direction indicating line that indicates the hitting direction may be provided on the upper surface of the indicator portion. Thereby, the direction of the hit ball can be recognized more clearly at the time of addressing, which can contribute to the reduction of miss shots such as pat mistakes.
[0046]
The hitting direction indication line is typically on the center of the face side portion and the back side portion in a direction substantially perpendicular to the face surface so as to indicate the center portion of the face surface (preferably the center position of the sweet spot). To extend. The length of the indicator line can be arbitrarily selected, and may or may not reach the end on the face side and the end on the back side of the indicator part. Further, the hitting direction indicating line is typically constituted by a straight line, but may be constituted by a line other than a straight line or may be constituted by an intermittent line. Further, the number of instruction lines may be either singular or plural.
[0047]
The hitting direction indicator line may be formed by providing an uneven portion such as a step or a groove on the upper surface of the index portion, such as applying a paint having a lightness and high saturation such as white on the upper surface of the index portion. May be drawn. Alternatively, potting may be performed by pouring resin or the like into the recess.
[0048]
The indicator portion may be provided with a central display portion for displaying the central portion in the longitudinal direction of the face side portion, that is, the central portion of the face surface. Thereby, it is possible to concentrate the consciousness on this part at the time of addressing. In addition, since a sweet spot usually exists in the center of the face surface, it is easy to hit a ball at the center of the sweet spot, which leads to reduction of miss shots such as put mistakes.
[0049]
For example, the central display portion is provided with a stepped portion at the center in the longitudinal direction of the face side portion, forming a concave or convex portion surrounding at least a part of the central portion, or drawing a line. It can be formed by dividing the central portion from other portions of the indicator portion. It is also conceivable to provide a central display portion by making the color or pattern of the central portion in the longitudinal direction of the face side portion different from the color or pattern of the upper surface of the indicator portion in a portion other than the central portion.
[0050]
As the shape of the central display portion, an arbitrary shape can be selected. For example, an ellipse, a circle, a shape close to these, a polygon, and the like are conceivable. Moreover, you may make it prescribe | regulate a part of center display part using the outer periphery of a face side part.
