Description

The present invention relates to a putter head and a putter used for putting in golf.

Putting in golf is a play in which a player puts a ball on the green or near the green into a cup (hole) using a putter. Each golf course has greens with various types of turf, slopes, speeds, etc. Therefore, it is important to have highly accurate directionality and stable putting with a sense of distance when putting.

In golf putting, the rule is to hit the putter sideways, and the putter must be looked down from above. When launching the ball, instead of aligning the face at a right angle to the cup and aiming straight at the cup, consider the height difference and slope of the green and create a spat between the ball and the cup. It is necessary to set the launch direction target point) and align the face surface at a right angle to the direction of the spat.

However, in conventional putters, as in Patent Document 1, it is not easy to align the face surface perpendicular to the spat just by drawing a line perpendicular to the face surface on the top surface of the putter head. direction error was likely to occur.

In golf putting, shape factors such as the position of the center of gravity and the moment of inertia of the putter head are also important. , inclination, speed, etc.), the player selected an appropriate putter.

In order to meet such demands, as in Patent Document 2, a putter head is combined with a plurality of parts in one putter, and the shape of the putter head is changed by changing the combination of the parts as necessary. There have also been proposals to adjust the position of the center of gravity and the moment of inertia of the ball, but due to the complexity of the structure, it was difficult to change the shape according to the conditions of the green, and the range of adjustment was narrowly limited.

Explain alignment procedures for golfers putting on the green.

First, the distance from the position of the golf ball to the cup, the slope, the grain of the lawn, etc. are checked. Then set the spat between the ball and the cup. Next, the face surface 7 of the putter head portion 2 is set in the spat direction. At that time, the most appropriate alignment line is selected according to the distance to the spat to focus on the spat. Align them perpendicularly.

Adjusting the face surface 7 to be more accurately perpendicular to the direction of the spat by using the double focus function of the second arc 10 formed concentrically in addition to the first arc 9. can be done.

After aligning the putter head 2 with respect to the spat, the putter head 2 can be viewed directly from the first cavity 11a to the eighth cavity 14b of the head 2 at the time of impact from take-back when hitting a ball. It is a design that allows a correct and straight take-back and a straight and accurate impact on the spat with the face surface 7.

By gazing at these cavities when aligning the face surface 7 with the spat at address, these cavities are input into the brain from vision, and if the take-back and impact cannot be performed accurately as an afterimage effect, the shape of these cavities will be visible. produce variations in In order to reduce the variation, it is possible to accurately line the golf ball with a stable stroke and spat by directly looking at these cavities from take-back to impact.

7A to 7D show the intersecting distances of the alignment lines that align the spat under various conditions such as the distance to the spat, the slope of the green, and the grain of the green when the putter head 2 is viewed from above. A golfer can improve the probability that the ball will be cup-in by accurately and correctly aligning the face surface 7 with the spat corresponding to each distance.

As an example of use, in the case of pattern A in FIG. 7, the cup is a line that slices to the right. It is necessary to focus the intersection of ' on the spurt.

In the case of pattern B, the cup 1 is a line that hooks leftward, but it is necessary to focus the spatter on the spatter 6 and focus the intersection of the alignment lines f and f' on the spatter.

In the case of the C pattern, it is a hook line with a long distance, and it is necessary to focus the spatter on the spatter 1 and focus the intersection of the alignment lines a and a' on the spatter.

In the case of the D pattern, the line is straight up to the cup 1, but since the distance is long, it is necessary to align the spatter with the spatter 4 and focus the intersection of the alignment lines d and d' on the spatter.

In this way, a putter and a putter head that have a function that makes it easier to focus on the spat in response to situations such as direction, distance, slope, and grain during putting by assuming a combination of seven alignment lines. It can be said.
