Description

The present invention relates to a golf putter that can be put while feeling the weight of a head at a concentrated point.

It is said that it is important to feel the weight of the head when putting golf. In fact, there are many types of putters with heavy heads. However, I'm not sure where the head feels and how it feels. I still don't know if I feel the weight with the grip, the head, or during the stroke. It may be because the weight of the ball, not to lose the rebound, or because extra force does not enter. As a result of searching for the keywords “putter head”, “sole”, and “protrusion” in the patent electronic library, there were 14 cases. Among them, (Patent Document 1) shows a clog-like projection of a clog that protrudes from the sole part of the putter head, and the head sinks in the lawn. A tooth-like projection of a book is provided, and the height of the ball is made higher so that the height of the ball core and the putter head coincide with each other. Landing on the ground. Since the invention of the present application requires a sense of delicate weight to sole the turf, it can be said that it is clearly different because it does not touch the ground under the turf. (Patent Document 2) shows a long rail-like protrusion along the face surface direction at the tip of the sole near the bottom of the face as shown in FIGS. This is because there is no OB, and as with the conventional theory of no OB, if the putter is duffed, the face orientation is corrected correctly. Obviously, the rail direction is provided in a direction perpendicular to the putting, and the length of the rail is as long as the length of the face. It can be said that the present invention is clearly different in that it is circular in order to concentrate and feel the weight of the putter.

There is no doubt that it is the center of gravity that senses the weight of an object. It can be said that the best stroke is when the center of gravity and the center of gravity of the ball are aligned with the target. However, since the putter has a configuration of a head and a shaft, the centroid of the figure of the head and the center of gravity of the putter synthesized with the shaft do not necessarily match. Moreover, it is complicated because it seems to be affected by the grip position of the shaft and how it is felt by the grip force. Normally, the physical center of gravity of the head is behind the shaft mounting position. However, the so-called core or impact point of the face surface that hits the ball is in front. The distance between them slightly affects the straightness of the stroke. That is, since the stroke draws a slight arc, if the distance between the center of gravity and the impact point is too long, the reproducibility error also increases and it becomes difficult to hit the core of the face. In addition, the concentration point set up at the time of address is vague. It cannot be said that the physical center of gravity feels weight. In putting, there is no doubt that concentration is important. It is easy to concentrate if it represents the weight. It is easy to feel the weight of the head if the putter is lifted at the address. In the case of putting, I want some concentration point rather than feeling at the center of gravity. However, the shape of the putter is also diverse and complex, and the centroids of the figures are difficult to understand, making it difficult to understand. Therefore, if it is an alternative circle, it is clear that the center is the centroid and the center of gravity, and it is easy to understand as an image of concentration. Also, the bottom surface of many putters is curved to cope with the height of people of various heights, to deal with individual differences in the shaft angle of the address, or to prevent duffing, so that a specific part is curved It's hard to catch. The feeling is not constant at every address. Therefore, it is possible to solve the problem by providing a circular flat surface projecting on the sole portion closer to the face side than the actual center of gravity of the head, so that it can be concentrated as an alternative weight center when lifting at the time of addressing. Furthermore, if you draw a center circle that matches the top and bottom on the upper surface of the putter head, it becomes a place where it is easier to concentrate visually, and you can create a concentration point that specifically feels the weight, and it can be said that the problem is solved.

In order to solve such a problem, the golf putter of the present invention has a circular shape with a flat surface tangentially or horizontally from the contact point of the curved sole portion of the putter head or a flat surface protruding from the sole portion. A circular shape is provided such that the center of the circular shape is located on the face side of the center of gravity of the putter head.

In addition, the golf putter of the present invention is characterized in that a hollow portion is provided in the circular shape of the flat surface of the sole portion.

In addition, the golf putter of the present invention is characterized in that a circular shape having a center that coincides with the circular center of the sole portion in the vertical direction is drawn on the upper surface of the putter head, or a circular shape that moves from there to the face surface side. .

Loosen the grip at the time of addressing, land the head on the green, hang it while feeling the circular flat surface protruding on the sole, and if you lift it, you can feel the weight of the head, the virtual center of gravity position. The position of the center of gravity helps to increase the concentration at the time of addressing when the image is superimposed on the impact point of the face. Another effect is that when the circular flat surface is matched to the green surface, the putting line is an ascending line, descending line, hook line, and slice from the inclination different from the inclination of the shaft in the normal flat line. The line can be read. There are effects such as concentration effect, line reading effect, and stable stroke while feeling weight. In addition, as it is said that there is no OB in the duffing, there is an effect that the stroke can be performed according to the line by the resistance of the projection of the sole even in the putting or the duffing. Since the concentration point is clear, it can be easily adopted as a routine. Above all, golf will become even more fun if the important concentration increases, leading to a higher score. If the circle of the sole is colored, such as white, the putter of the cart that puts the putter upside down makes the identification of the owner obvious, making it colorful and fun. It's also fun to attract your friends when you hole out in each hall.

Front view from the circular face direction of a flat surface provided tangentially from the contact of the curved sole part of the putter head Front view of the flat surface protruding from the sole part of the putter head from the circular face direction A bottom view of the flat surface drawn from the bottom of the circular putter head. An example of a circular shape with a flat surface drawn on the sole, with the height on the circumference and the height of a small circle at the center aligned, and a recess in the middle An example of a circular shape with a flat surface drawn on the sole part, with a concave part in the concave part, and a uniform height. An example of a circle with a flat surface drawn on the sole, with a groove in the stroke direction and the same height in the remaining stroke direction An example of a circle on the upper surface of the putter head centered on the top and bottom of the circle center of the sole An example of a circle in which the circle on the upper surface of the putter head in FIG. 7 is moved to the face side. In the case of a putter with an upper surface that is two steps away, the upper rib portion and the lower upper surface portion are depicted as an integral circle when viewed from above.

A circular shape with a flat surface is provided on the sole of the putter. The size of the circle is less than the size of the ball for concentration. The center of the circle is coincident with the center of gravity of the head or between the impact point of the face. We need an image that will not lose to the impact or reaction force of the impact of the ball. I would like to have a diameter of 2cm or more. It is desirable that the circular face side be as close as possible to the impact point. If the protrusion is too large, it will duff. The circular flat surface may be formed as a whole even if it is not flat on the entire surface. For example, a flat surface with the same height around the circumference may be formed, and the surface may be hollowed out, or may be uneven as a whole and the height of the convex surface may be on the same plane. Naturally, the sole part cannot be seen from above, so an image appears when a circle with the same center position is drawn on the upper surface of the head. If there is a mark at the center, it becomes a more concentrated point, and if a through-hole is provided, the center of gravity and the eye position are overlapped and determined by looking into the center, and it can be said that there is a synergistic effect as a routine. Coloring the back and front circles will make it even more fun. Furthermore, it can be said that moving the circle to the face side is an easy way to create an impact image.

3 is an example of a circular flat surface of the sole portion, FIG. 3 is a circular shape of a generally flat surface, and FIG. 4 is a flat shape in which the height of the convex portion around the circumference and the height of a small circular shape in the central portion are equal. Fig. 5 shows an example of a rounded surface with the height of the concavo-convex raised and flat, and Fig. 6 shows an example of a rounded surface with the height of the concavo-convex row aligned in the putting line direction. is there.

In an example of a putter with a large head and a top surface that is not two-tiered, a circle with the same size as the ball can be drawn. In FIG. 7, the center of the upper and lower sides coincides with each other, and the size of the circle is a slightly smaller circle on the upper surface. FIG. 8 shows an example in which the circular shape of the upper surface is drawn close to the face surface side. In other words, it is desirable to be close to the impact point to some extent. You may mark an impact point at that position. Any of the circular shapes may be smaller than the circular shape of the sole portion.

In the putter with a thin face portion shown in FIG. 9, the face surface is thin, the rib width is small, the head width is small, and the upper surface has two steps. For this reason, the centroid of the figure is on the face side with respect to the stepped putter, and the circular size of the flat surface of the sole part must be relatively small. The circular shape on the upper surface is a circular shape including the rib portion. In other words, the upper surface of the rib and the upper surface of the lower putter are drawn so as to have a circular shape when viewed from above, although they are different. Of course, the size of the circle will be relatively small to fit within the width of the putter. The impact point of the face may be marked on a circular line.
