Abstract

(57) [Summary] [Purpose] To provide a sand wedge capable of performing a bunker shot without feeling anxiety or fear. [Structure] A face 2 of a sand wedge 1 is formed into a substantially circular shape, and a hosel 4 connected by a bridge 3 is integrally formed. On the face 2 of a substantially circular shape,
A number of parallel score lines 5 are engraved in a virtual circle C drawn concentrically with the face 2. Because it has a round and large face, you can take a bunker shot with confidence without feeling anxiety or fear.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a sand wedge.

[0002]

[Prior Art and its Problems] When performing a bunker shot with a conventional sand wedge, the technique of swinging outside with the face open and the sand explosion by the swing that intentionally creates a double (below It is called an explosion) and requires a technique such as hitting a ball with the sand. Therefore, many golfers are not good at bunker shots.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a sand wedge that can be used for bunker shots without feeling psychological anxiety.

[0004]

In order to achieve the above object, the sand wedge of the present invention as set forth in claim 1 has a face having a substantially perfect circular shape and a virtual circle concentrically drawn on the face. It is characterized by engraving score lines inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a sand wedge 1 according to the present invention,
2 is a side view of the same, and FIG. 3 is a bottom view of the same. The shape of the face 2 of the sand wedge 1 is formed into a substantially perfect circle, and the hosel 4 connected by the bridge 3 is integrally formed. On the substantially circular face 2, a large number of parallel score lines 5 are engraved in a virtual circle C drawn concentrically with the face 2.

As shown in the explanatory views of FIGS. 2, 3 and 4, the sand wedge 1 of the present invention has a leading edge 6 having an arcuate curvature, a sole 7 and a crown 8 of a face 2. Unlike the conventional sand wedge (Fig. 4 (b)), the shape of the back surface 9 is rounded in all directions R
A part of the spherical state B having (FIG. 4A) is used. This is because the sphere is an object with excellent straightness. However, with a shape in which a part of the spherical state B is used, the straightness after being driven into the sand is excellent, but the kickback (bounce) is too large. Therefore, the rear surface B of the spherical state B
A cavity 10 is formed by removing a and removing the meat in a circular shape in the removed portion. The loft is formed at 58 °.

The above-mentioned sand wedge 1 of the present invention is excellent in straightness after being driven into sand at the time of a bunker shot, and also kicks back (vans) at the time of driving.
Can be given an appropriate momentum. Therefore, it is easier to enter the sand than the conventional sand wedge, and it is easy to slip out, so that it is possible to deal with any lie, and it is also possible to approach from the divot.

Further, the sand wedge has an explosive effect as the distance L from the leading edge 6 to the crown 8 increases. Since the conventional sand wedge has a shape as shown in FIG. 5 (a), the distance L cannot be maximized unless the face portion is used obliquely in order to maximize the explosion effect. On the other hand, in the sand wedge 1 according to the present invention, as shown in FIG. 5B, since the shape of the face 2 is a substantially circular shape, the leading edge 6 to the crown 8 are formed.
Since the distance L to is equal, the maximum explosion effect can always be exerted. Also, the spin amount of the hit ball is large.

[0009]

As described above, in the sand wedge of the present invention, the shape of the face is made into a substantially circular shape, and score lines are engraved in a virtual circle concentrically drawn on the face, which is round and large. Since you don't have to open your face when swinging, you can take a bunker shot with confidence without feeling anxiety or fear. Further, the shape utilizing a part of the spherical shape is excellent in that it has a large explosive effect because the straightness is high and the face is large.
