Abstract

As a scale provided on a grip of a putter with a distance measuring function, a putter having a structure that is easy to measure and does not impair the image in design is provided. The scale is represented by, for example, a triangle, a quadrangle, a pentagon, or a complex figure at a position of 10 cm units such as 30 cm, 40 cm,... For a figure such as a pentagon whose precise scale position is difficult to understand, a point or line segment is included in the center position to facilitate measurement. In addition, each small figure is configured to be bilaterally symmetric or point symmetric so that it is easy to read regardless of the dominant eye of the player. [Selection] Figure 3

Description

        The present invention is a putter with a distance measuring function that can read the distance to the cup and the take-back amount of the putter suitable for it when putting golf, and provides a way to put a scale that is easy to measure with a design that is not just a numerical display It is.

The conventional measuring method was measured by the number of steps from the ball to the cup, but the error was large, and considerable experience was required to measure accurately.
On the other hand, the method described in Japanese Patent Application No. 2005-504504 suspends the grip end of the putter at the ball position on the green according to the height of the eyes, and the eyes and putter when looking at the cup with the arms extended. Attach the graduation to the grip to determine the number of distances from the intersection point to the cup, and at the same time treat the putting as a pendulum and write the optimal takeback amount necessary to roll the distance to the cup on the scale above. It provides a means of reading instantaneously in motion.
On the other hand, the actual application 2006-002051 provides means for providing a thin plate at the shape of the through hole provided at the reference position and the end of the grip in order to easily match the reference position of the grip scale with the eye height. In addition, instead of numerical display, the scale is also expressed by the number of small figures.

        Since the scale provided in the actual application 2006-002051 is for reading the optimum takeback amount by the number of small figures, the scale is complicated and there is a problem in expressing the entire grip with a simple design.

The present invention solves the problem of the actual application 2006-002051. For example, the scale which becomes a knot of take back amounts of 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm has three, four, five, six, Adopt small figures that customarily remind you of the numbers 7 and 8.
However, since graphic representation requires an area, it has a problem that the scale position is ambiguous. As a solution to this problem, a small point (including a polygon) indicating the position of the scale, a line segment, an apex angle, etc. are included in the center of the small figure.

        Since the total number of figures representing the scale is reduced at once, the overall design of the grip can be expressed concisely. Therefore, patent no. The method of expressing grip design has the effect of expanding at once.

FIG. 1 shows the principle of standing on a green having an inclination angle θ and reading the optimum takeback amount with the scale Y of the grip A based on the distance X from the ball position B to the cup C.
2 shows that when putting with pendulum half length R on an inclined green, the potential energy of the equivalent weight M of the putter tip born by the takeback of the swing angle β is converted into the kinetic energy of the partially hit ball m. The energy is lost to the frictional heat due to the resistance μ of the turf and the potential energy due to the green inclination angle θ. Details are described in Japanese Patent Application No. 2005-504504, and are omitted here.
FIG. 3 shows an example of small figures (3a to 3f) in which a scale is provided on the basis of the through hole 2 provided near the end of the grip 1 and the numerical value is expressed in 10 cm increments from the maximum notation position of the takeback amount. For example, take back 80cm is a composite 3a using two squares, 70cm is a composite 3b using squares and three dots, 60cm is a composite 3c using two triangles, 50cm is a single pentagon 3d, and 40cm is a square. 3e and 30cm are triangles 3f, and all these figures are symmetrical. The reason is that it can be read regardless of the dominant position of the player. Moreover, at least one point 4a, several point rows 4b, apex angle 4c, etc. are included on the approximate center line of the figure so that the position of the scale can be accurately understood.

FIG. 4 shows an overall image of the present invention, and the small figures shown in FIG. 3 are arranged on each scale. However, since the takeback amounts 23 cm, 26 cm, 33 cm, and 36 cm mean 3 cm and 6 cm of the 20 cm level and 30 cm level, respectively, the two locations are identified by one point 5 a and two points 5 b.
Further, the takeback amounts of 45 cm and 55 cm mean half of the 10 cm interval, and are expressed by rounded line segments 6a and 6b, respectively. Similarly, take back 70 cm means the middle between 60 cm and 80 cm, and a small circle 7 is substituted.

FIG. 5 shows an application example of the present invention. Two horizontal numbers (8a to 8f) are arranged point-symmetrically, and the point 9a and the line segment 9b indicating the point-symmetrical position of the figure also express the position of the scale. is doing.
In this way, the scale for reading the takeback amount is minimized, and numerical information is made into a figure that can be customarily read from the normal living environment, greatly expanding the possibilities of grip design.
