Description

  In the present invention, the player's effectiveness is perpendicular to the ball hitting surface of the putter head and is located right above the line passing through the sweet spot (hit point), and is always constant even if not right above. The present invention relates to a golf putter or a member attached to the golf putter provided with a visual recognition means for performing a putter stroke at the position of the effect.

  In general, the skill of a golf putt greatly affects the player's score, and therefore various ideas have been made to improve the success rate of the putt. For example, in a putter head of a golf club, the toe side and the heel side are inclined sides of 90 degrees or more with respect to the ball striking surface, and the ball striking surface can be accurately directed in the target direction (see Patent Document 1). Is set to approximately minus 45 degrees so that the ball can be launched toward the target even if the orientation of the club face is not accurate (see Patent Document 2).

  Also, as a golf putter that keeps the position of the player's eyes or head relative to the putter head and increases the success rate of the putt, a viewing object having a light-transmitting slit parallel to the hitting surface is fixed to the putter head. In addition, a clear vision part capable of receiving light from the outside is formed on the lower side of the visible body, and the player can confirm his / her head position by looking through the clear vision part. There is a thing (refer patent document 3). However, since this golf putter has a complicated structure and a passage slit is provided in parallel with the ball striking face, it is possible to confirm the position of the head in the front-rear direction of the putter head. It cannot be identified whether the head is on the toe side or the heel side of the putter head, or whether the head is located on the hitting line of the putter head.

  On the other hand, when the player puts on the green, as shown in FIG. 1, the target line a and the hitting line b of the putter head 1 (perpendicular to the hitting surface 2 of the putter head 1 and the sweet spot 3 (hit point)) Basically, the player hits the ball by stroking the putter, and the player's effectiveness or head is positioned on the toe side of the putter head, that is, on the right side of the hitting line toward the target. Then (FIG. 1 (A)), the player tends to address the putter head 1 in this line-of-sight direction and backswing along this direction (b). As a result, the ball 9 moves toward the target line. And deviate to the left (I). Further, when the player's effect or head is located on the heel side of the putter head, that is, on the left side of the hitting line (FIG. 1B), the putter head 1 is addressed in this line of sight, and in the opposite direction to the above. It is known from experience that there is a tendency to address and backswing along this direction (d), so that the ball 9 deviates to the right of the target line (c). It is a common belief that positioning on the hitting line of the putter head is important for successful putting.

As a thing that incorporates such putting theory, a practice tool that trains so that the ball mounting part of the putting practice mat is a mirror and the practitioner's effect and head are directly above the ball is not commercially available. However, even with training, it is difficult to perform putting as practiced in the actual green.
In addition, as a putter incorporating such a putting theory, an extension portion perpendicular to the putter is provided and markers are provided on both sides thereof (see Patent Document 4), or a protruding portion substantially perpendicular to the putter There is one in which both sides are painted (see Patent Document 5). However, these putters only make it visible whether or not the player's head is on the hitting line of the putter head.
On the other hand, there are many players who have individuality, and there are many players who cannot get used to positioning their effectiveness or head on the hitting line of the putter head, and even in such a player, a putter that can perform stable and accurate putting is desired. In addition, there are many players who do not hold the putter's sole surface parallel to the ground but address the toe side or the heel side of the putter head slightly, and they are hit. It is desirable to have a putter that can be made to occur.

JP 2004-141594 A Japanese Patent Laid-Open No. 11-253589 Japanese Patent Laid-Open No. 2001-218879 Japanese Utility Model Publication No. 52-11456 Japanese Utility Model Publication No. 51-100150

  The object of the present invention is to incorporate the above putting theory into the golf putter itself, and to provide a visual means capable of adjusting from such a theoretical head position to an optimum head position for an individual player. Therefore, it is an object of the present invention to provide a golf putter that enables a stable and accurate patching and has a simple structure and can significantly improve the success rate of putting.

As a result of diligent research, the present inventor has positioned the player's effectiveness on the putter head itself of the golf putter, right above the hitting surface of the putter head and on the line passing through the sweet spot (hit point). In addition, it has been found that the above-mentioned problem can be solved by providing a visual recognition means provided with a visual recognition means for putting a putter stroke at a constant effect position even if it is not located directly above. That is, the present invention is as shown in the following (1) to (9).

The member described above, wherein the member is provided.

According to the present invention, it is possible to provide a golf putter that incorporates the above-described putting principle into the golf putter itself and can significantly improve the putting success rate with a simple structure.
The golf putter according to the present invention can be set correctly on a line (hit line) passing through the sweet spot with its effectiveness or head orthogonal to the hitting surface of the putter head and putting on the line easily. . On the other hand, such a theoretical head position is not suitable for all players, and the present invention makes it possible to adjust the head position from the theoretical position to a position suitable for the individual player, and visually recognize the position. By providing the means for doing so, the present invention can be applied to all players, and the ball launch direction is stabilized, and the success rate of putting can be improved without shifting from side to side with respect to the target line.

  According to the present invention, the player's effect or head is perpendicular to the ball hitting surface of the putter head and is positioned directly above the line passing through the sweet spot, and is always constant even if it is not positioned directly above the putter head. The present invention relates to a golf putter characterized by providing visual means for putting a stroke at the position of the head or effect.

A first example of a preferred embodiment of the present invention is shown in FIGS.
In this golf putter, a putter head 1 is attached to the tip of a shaft 10 having a terminal grip portion, and on the extending member 4 behind the hitting surface 2 of the putter head 1 with respect to a sole surface M at the bottom of the putter head. A rising piece 5 rising vertically is provided. In other words, the golf putter of the present invention has a flat portion where at least a part of the bottom surface of the putter head becomes a sole surface. The rising piece 5 is provided on a line b (hereinafter referred to as the hitting line of the putter head) b that is orthogonal to the hitting surface 2 of the putter head and passes through the sweet spot 3. Are respectively provided with markers 6 and 6 'on the upper surface of the extending member 4 of the putter head.
The height of the rising piece 5 and the position of the marker are set so that when the player's effect or head is not on the hitting line, the line of sight is obstructed by the rising piece and all or part of the marker cannot be visually recognized.
The marker is composed of a plurality of strip-shaped markers and is provided in parallel with the rising piece.
The band-shaped markers are colored and at least the adjacent band-shaped markers have different color schemes, or the plurality of band-shaped markers are arranged at the same width as the band-shaped markers. In the latter case, an uncolored putter head portion sandwiched between two colored band-shaped markers can also be a band-shaped marker. The width of each strip marker is preferably the same, and the width is 0.5 mm to 5 mm, preferably 1 mm to 3 mm. These strip markers are symmetrical with respect to the rising piece including the color scheme. It is desirable to provide it.
In the above golf putter, the rising piece and the marker are provided on the upper surface of the extending member in the putter head. However, the rising piece and the marker may be provided as shown in FIG. 4 without providing such an extending member. .

FIG. 5A shows that the effect 7 of the player is on the near side (heel side) with respect to the hitting line, and therefore one of the markers 6 ′ provided on the opposite side (toe side) of the hitting line b of the putter head. This shows how the part disappears. This is the same when the player's effect is on the other side (toe side) of the hitting line. In this case, a part of the marker 6 provided on the heel side of the hitting line b of the putter head cannot be seen ( FIG. 5 (B)).
Therefore, when putting using this putter, if the head is moved so that all the band-like markers on the markers on both sides can be seen across the rising piece 5, the head position is on the hitting line b of the putter head. become. In many cases, if the putter stroke is made at this head position, the putter success rate is improved. On the other hand, there are individual differences among players, and there are cases where the putter success rate is lowered at the head position on such a hitting line. In such a player, the position where a part of the marker cannot be seen is the optimum position, and the position of the head can be said to be the reverse of which one of the plurality of markers of the marker is not visible. It is possible to know by visually checking which band-shaped marker is visible. For example, when all the belt-like markers on the heel side are visible and one belt-like marker on the rising side is not visible among the belt-like markers on the toe side, the player's head position is slightly on the heel side. You can see that However, if this player has a high putter success rate even at the head position, the head position that looks like this is the optimal position, and if the position that looks like this is memorized, the head position is Stable putting can always be performed at the optimal position, and the success rate of putting improves.
In addition, in a player who does not hold the sole of the putter parallel to the ground and addresses the toe side or the heel side of the putter, positioning the head directly above the rising piece is not necessarily on the hitting line in the true sense. It will not be positioned (FIG. 5C).
The true hitting line is a line that is perpendicular to the hitting surface and passes through the point where the ball is actually hit (hit point 3 '). The hitting line of the putter head is the putter sole on the ground. This is distinguished from the true hitting line on the premise of holding in parallel.
Even in such a player, when the position of the head or effect is on the hitting line in the true sense, it is necessary to remember which of the belt markers can be seen, and even in such a player, the head or effect is effective. It can be positioned directly above the hitting line in the true sense.
The player can perform an accurate stroke by putting the head or effect on the hitting line of the putter head, for example, by putting according to the following routine.
(1) First, put the putter parallel to the ground, and make sure that the effect or head is right above the rising piece of the putter head.
(2) Next, lift the toe side or heel side of the putter and confirm that it is on some line and hit.
In other words, each of the band-shaped markers of the present invention functions as a scale for visually recognizing the optimum position of the player's individual head, and the visibility is improved by coloring.
The rising piece 5 is preferably elongated in the direction of the hitting line. In putting, it is an iron rule to make a straight stroke along the target line, and the markers 6 and 6 'composed of the rising piece of the shape and the band-shaped marker serve as a guide for performing such a putting stroke. In this case, it is desirable to color the upper surface of the rising piece. However, when the color of the band-shaped marker and the color of the upper surface of the rising piece are adjacent to each other, they are arranged so as to stand out. Thereby, the visibility of the rising piece and the marker is improved, and not only the guide function but also the effective position confirmation function is improved.

A second embodiment of the preferred embodiment of the present invention is shown in FIGS.
In this golf putter, a putter head 21 is attached to the tip of a shaft 10 having a terminal grip portion, and a prism having a cross section of an isosceles triangle (including an equilateral triangle) is provided behind a hitting surface 22 of the putter head 21. The member 23 has one side surface parallel to the sole surface at the bottom of the putter head, and the other two side surfaces (S, S ′) constituting the isosceles side of the cross section having the same inclination angle and the toe side and the heel of the putter head. It is provided so as to be inclined to each side. Further, the apex line c formed by the two inclined surfaces S and S ′ is provided on the hitting line b in the putter head 21, and the markers 26 and 26 ′ are provided on the two inclined surfaces S and S ′. Is provided.
The position where the marker is provided is preferably a position that is symmetrical with respect to the opposite position of the two inclined surfaces, specifically, the apex line c.
The shape of the marker may be any of a band, a line, a circle, a square, a triangle, a star, and the like, and may be a scale provided in an inclined direction. It is preferable that these markers have the same shape. .

In the case of this golf putter, as shown in FIG. 8, when the player's effectiveness or head is not on the hitting line b of the putter head 21, for example, the effectiveness is on the front side (heel side) of the hitting line of the putter head 21. At this time, the marker located on the far side (toe side) of the hitting line appears to be compressed in the direction orthogonal to the hitting line of the putter head, compared to the marker located on the heel side (A).
On the other hand, when the player's effect or head is on the other side (toe side) of the hitting line b of the putter head 21, the marker located on the near side (heel side) appears to be compressed (B). Only when the effect of is on the hitting line b of the putter head 21, the two markers appear to have the same shape (C). For example, when a band-shaped marker extending in the hitting line direction is provided on two inclined surfaces, one marker appears to be a thin band compared to the other marker.
Therefore, when putting using this putter, the effect or the position of the head can be confirmed by the shape of the two visually recognized markers. It becomes possible to adjust the position of the head to the position.

In the golf putter of this embodiment, the markers provided on the two inclined surfaces S and S ′ may be combined to represent one figure. Such a figure can be seen as a complete figure only when viewed from directly above the hitting line. For example, when the markers on the two inclined surfaces S and S ′ are formed so as to be a perfect circle only when viewed from directly above the hitting line b of the putter head as shown in FIG. 9A, the effect is on the hitting line. If not, it looks like a deformed ellipse (FIG. 9B).
The shape when viewed from directly above such a hitting line may be, for example, a regular square, a regular triangle, a star, or the like in addition to a perfect circle, or a character pattern. Even with such a marker, it is possible to adjust the position of the head to the optimum position of the individual player.
The apex line c formed by the two inclined surfaces S and S ′ also functions as a guide for performing the putting stroke. For this purpose, the apex line is elongated by extending the prism member in the direction of the hitting line. In order to further improve the visibility, it is preferable to color the top ridge line.

  Further, as shown in FIG. 10A, such a prism member 23 may be provided on the member 4 extending behind the striking surface of the putter head, and FIGS. 10B and 10C. May be provided on the upper surface of the putter head.

Furthermore, a third embodiment of the preferred embodiment of the present invention is shown in FIGS.
In this golf putter, a putter head 31 is attached to the tip of the shaft 10 having the end grip portion, and a prismatic member 33 having a trapezoidal cross section is provided behind the hitting surface 32 of the putter head 31. At this time, the two parallel side surfaces of the prism member 33 are provided so that the smaller area is the upper surface and the larger area is the bottom surface, and is parallel to the sole surface M of the bottom portion of the putter head. The two side surfaces S and S ′ are provided so as to incline toward the toe side and the heel side of the putter head at the same inclination angle.
Further, a center line e which bisects the upper surface of the prism member 33 into the toe side and the heel side is positioned on the hitting line b of the putter head, and further, the markers 36, 36 ′ are placed on the two inclined surfaces S, S ′. Is provided. The positions where the markers are provided are preferably symmetrical positions with the two inclined surfaces S and S ′ facing each other, specifically the center line c.
The shape of this marker may be any of a band, a line, a circle, a square, a triangle, a star, etc., or may be a scale provided in the slope height direction, and such a marker has the same shape. Is preferred.
Also in the case of this golf putter, as in the golf putters shown in FIGS. 6 to 10 above, when the player's effectiveness or head is not on the hitting line of the putter head, the markers on the two inclined surfaces S and S ′ are respectively putter heads. In the case where the length in the direction orthogonal to the ball hitting line is different and putting, the optimum position of the effect or the head position can be confirmed by the shapes of the two markers visually recognized.
Further, in the golf putter of this embodiment, the markers provided on the two inclined surfaces S and S ′ facing each other similarly to the putter shown in FIG. 9 may be combined to represent one figure. Good. Similar to the above, it is possible to adjust the position of the head to the optimum position of the player by the visually recognizing shape of these markers.
Further, the center line e on the upper surface of the prism member 33 also functions as a guide for performing a putting stroke. For this purpose, the prism member 33 is elongated in the hitting line direction to extend the center line, and further visible. In order to improve the property, it is preferable to form the center line e as a convex line or a concave line, or to color it. Furthermore, this trapezoidal trapezoidal prism member may be provided on a member extending behind the ball striking face of the putter head, or on the upper surface of the putter head, like the golf putter of FIG.

The inclination angles of the inclined surfaces S and S ′ in the second and third specific examples are 30 to 85 degrees, preferably 45 to 80 degrees, more preferably 50 to the other surfaces of the prism member. It is preferable to set the angle to 70 degrees, and when the inclination angle is large, the visual shape of the two markers on the inclined surface according to the position of the effect or the head changes more markedly. However, when the angle exceeds 85 degrees, the marker shape itself is difficult to recognize.
In the case of putting using the golf putters of the second and third specific examples described above, the positions where the markers provided on the two inclined surfaces S and S ′ appear to be the same shape or the two inclined surfaces S and S ′. It is only necessary to move and fix the effect or the head to a position where the marker across the surface looks the correct shape, or to a position where the marker becomes the optimal visual shape of the player's individual, and put it at that position.
In the first, second, and third specific examples, the visibility of the marker is particularly important. In order to improve the visibility, it is preferable that the marker is colored in a color different from the color of the putter head, and the convexity is further increased. You may form in a shape part or a concave part.

  In the present invention, each component member of the putter head including the visual recognition means of the present invention may be integrally formed at the time of manufacturing the putter head, and is fixed by fixing means such as welding and screwing after the formation of each component member. Thus, a putter head may be created.

  On the other hand, in the invention of the present application, the visual recognition means in the first to third specific examples described above are created as members separate from the golf putter, and the golf equipment that the player wears on his / her own golf putter. It is also possible.
