Problems solved by technology

[0007] This makes it difficult to hit the ball in the exact target direction during the swing
In addition, for a putter configured to assist an accurate swing by attaching a direction indicating body, etc., its manufacture is not necessarily easy.

Embodiment approach

[0024] Figure 1A and 1B It is explanatory drawing which shows the structure of the putter 1 which is one embodiment of this invention. Figure 1A Indicates the situation of observing putter 1 from vertically above when addressing the ball, Figure 1B Indicates the state of the putter 1 viewed from the heel side. Such as Figure 1A and 1B As shown, the putter 1 has: a club head 10 , a shaft 3 and a hosel 20 connecting the club head 10 and the shaft 3 . The shape of the head 10 is symmetrical in the heel-toe direction from the heel side toward the toe side. In addition, in the club head 10, the club face 11, which is the hitting surface of the ball BL, faces slightly vertically upward. Additionally, if Figure 1A As shown, in the putter 1 , the head 10 is symmetrical in the heel-toe direction, so the center of gravity CW of the head 10 is located at the center of the head 10 in the heel-toe direction.

[0025] The hosel 20 has: a rising portion 21 connected to the center po...

Deformed example 1

[0043] In the above embodiment and modification of the hosel shape, the position where the imaginary line 4 passes is visually confirmed through the region where no parts constituting the hosel 20, 20a, 20b exist, but a transparent configuration may also be used. The parts of the hosel are configured to visually confirm the position where the imaginary line 4 passes. In order to visually confirm the position where the virtual line 4 passes through the members constituting the hosel, the hosel may be formed of a transparent material such as glass or plastic. In this case, in order to easily confirm the direction in which the virtual line extends, at least the center of the extended portion of the hosel made of a transparent material may be left to paint the outer surface of the hosel, or the extended portion may be painted. Draw an indicator line near the center of the .

[0044] In addition, as another form in which the position where the virtual line 4 passes through the mem...

Deformed example 2

[0046] In the above-described embodiment, in order to enable visual confirmation of the position where an imaginary line passing through the center of gravity of the head and perpendicular to the club face passes and confirmation of the direction in which the imaginary line extends, the extended portion 22 of the hosel 20 Slots 24 are provided that are long in the extending direction of the virtual line as viewed from vertically above, and a linear region through which the virtual line 4 passes can be visually recognized. However, as long as at least two points on the virtual line can be visually confirmed, the extending direction of the virtual line can be confirmed. In order to visually confirm at least two points on the imaginary line, for example, the hosel may be provided with at least two or more holes separated in the extending direction of the imaginary line as viewed from vertically above. Among them, it is preferable to provide a slot hole because it is easier to vis...

Abstract

The invention relates to a golf putter, and the putter comprises a putter head (10), a putter neck (20) and a putter shaft (3). The putter neck (20) connects the putter head (10) and the putter shaft (3) and extends from the putter head (10) toward a putter face (11) side. The putter neck (20) can be determined visually to pass through a center of gravity (CW) of the putter head (10) and two points on a phantom line (4) which is orthogonal to the putter face (11), and the putter neck (20) can determine the extending direction of the phantom line (4).

Description

technical field [0001] The present invention relates to a golf putter, in particular to a putter capable of swinging more accurately. [0002] This application claims priority based on Japanese Patent Application No. 2014-174789 for which it applied in Japan on August 29, 2014, and uses the content here. Background technique [0003] Since the number of swings accounts for a large part of the number of shots in golf, it is important to perform accurate swings while reducing the number of swings in order to improve golf scores. Therefore, in order to perform a swing accurately, when placing the ball, make the lines drawn on the surface of the ball and the linear marks (hereinafter collectively referred to as "mark lines") coincide with the target direction such as the hole, and place the ball Play along the direction of the marked line. Specifically, the player imagines a target line connecting the ball to the hole, and aligns the marked line with the imagined target line. ...
