Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to golf putters.

[0002]

[Prior art]

 Golf putters are used exclusively on greens, unlike wood-headed clubs used on tees and fairways, and metal-headed clubs used on fairways or sandpits. It is well known that they are not.

[0005] The above-mentioned wood head is designed such that a plurality of ridges are extended downward in the same plane as the hitting surface, and the ridges are extended to a bottom surface (sole) which is rearward, so-called clogs are provided. Was done.

However, the clogs described above are intended to reduce the frictional resistance against the ground when hit, and require that the front surface of the clogs be in the same plane as the hitting surface.

[0005] On the other hand, a putter dedicated to the green is one that taps the ball lightly and does not hit the ball with force and seeks an appropriate flight distance.

On the green, the take-back from the address takes place and the golf ball hits after the downswing. However, in the hitting state shown in FIG. Ball does not run. In Fig. 5 (c), the hole is forward-rotated in the direction of the arrow (overspin), the influence of the grass is small, the direction is stable, and the hole rolls well.

[0007] However, regarding the above-mentioned overspin, the bottom surface of the putter body metal fitting is landed and addressed, and if it is taken back in that state, it is easy to take back in the straight line direction facing the tapping direction. Lifting mm causes mental stress and disturbs tapping.

[0008] Therefore, if take-back is performed from a state where the take-up is performed several mm before the address, the take-back direction may be disturbed, and the hitting direction, overspin, and the like may be disturbed.

In order to raise the bottom surface from the ground, linear projections, plate-like projections or hemispherical projections are formed on the bottom surface (JP-A-8-150233, JP-A-8-215358, and JP-A-8-215358). New model registration No. 3001052). However, in these inventions, there is a problem in that the resistance between the protrusion and the turf is large during takeback or downswing, and the resistance to the turf based on the feel of the hand or arm increases the mental burden of the player.

In addition, the linear, plate-like, and hemispherical projections do not have a peak in the longitudinal direction (left-right direction) and the front-back direction of the putter, and do not have a conical surface on the outer periphery of the peak. There is a problem that the ground contact area is large, the frictional resistance with the grass or the ground during takeback or downswing is large, and it is difficult to perform smooth and stable takeback and downswing.

Further, since the conventional projection does not have a top portion in the longitudinal direction (left-right direction) and the front-rear direction of the putter, it is difficult to tilt the putter body front, rear, left and right at the time of addressing. Because it was difficult to set the front, rear, left, and right inclinations freely, positioning of the putter at the time of setting required extra thinking effort and was also a factor that hindered simple takeback actions.

[0012]

[Problems to be solved by the invention]

 In this model, the bottom surface of the putter body is easy to lift slightly (several mm) when addressing, but the takeback is easy to be linear in the hitting direction, and at the same time it is easy to take horizontality, and the ball is easily overspun (forward rotation) during downswing and used. The purpose is to obtain an easy pattern.

[0013]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a putter body metal fitting having a ball hitting surface on a front surface and a bottom surface facing rearward from a lower end edge of the ball hitting surface. The golf putter according to the first invention, wherein the front end of the golf putter is formed substantially stepwise at the rear part of the lower end edge, and the top of the protrusion is formed in the hit area of the ball hitting surface. The golf putter according to any of the first to third inventions, wherein the golf putter according to the first or second invention has a conical shape, and the protrusion has a pyramidal shape. The golf putter according to any one of the first to third aspects of the present invention is configured such that the tops of the protrusions are slightly rounded or flattened.

[0014]

[Embodiment of the invention]

 The putter body metal fitting 3 is attached to the tip of the shaft 7, and the metal fitting 3 has a ball hitting surface 1 (face) formed on the front surface thereof, and has a convex arc shape that projects rearward from the convex lower end edge 1 'of the ball hitting surface 1. A shaped bottom surface 2 (sole) is formed.

A projection 4 whose center line is parallel (FIGS. 1 to 3) or perpendicular (FIG. 4) to the bottom edge 1 ′ of the ball hitting surface 1 is provided on the bottom surface 2, and a front end 4 ′ of the projection 4. Is formed substantially stepwise at the rear of the lower edge 1 '.

The projection 4 has a top 4 ″, and is formed into a conical shape in which an inclined surface 4 a is formed from the top 4 ″ toward the bottom 2, as shown in FIGS. 1 (b) and 2 (b). As shown, the top 4 "is included in a hit area (hit area) 5 of the ball hitting surface 1. The position of the hit area 5 is slightly different depending on the type as shown in FIG. The pyramid is a rectangular quadrangular pyramid (Fig. 1 (a) (b) (c) (d), Fig. 2 (a) (b) (c) (d), Figs. FIG. 6 (b) is a conical shape (FIG. 6 (c)), and the top 4 ″ is rounded or cut flat.

The height from the bottom surface 2 to the top portion 4 ″ is about 10 mm or less or about 10 mm. The grip 8 at the upper end of the shaft 7 is gripped and the ball hitting surface 1 hits the ball 9 on the green 6. In the static state, the hit point p of the ball hitting surface 1 becomes lower than that of the conventional type, so that overspin is easily applied.

Therefore, as shown in FIG. 1 (a), when the top 4 ″ is grounded on the ground 6 ′ of the green 6, and the ball hitting surface 1 is applied to the ball 9 grounded on the ground 6 ′ to address the player, The lower edge 1 'appears to float above the ground 6', and after takeback, can swing down in the direction of the arrow b without lifting the main body fitting 3. In this way, the hit area 5 of the ball hitting surface 1 is reduced. As shown in FIG. 1 (a), the hit point p 'of the ball 9 is hit, and the ball 9 rotates in the direction of arrow a, overspins and rolls toward the hole.

The top 4 ″ is in contact with the ground 6 ′ under the grass 6 ″ of the green 6, and the maximum contact width 2 d with the grass 6 ″ is about の of the maximum contact width 2 D of the semicircular projection 4 b, The friction resistance with turf 6 "is small. And the inclination of the putter body centering on the grounded top 4 "is easy and it adapts to the address posture before takeback.

[0020]

[Effect of the invention]

 Since the present invention is constructed as described above, the lower edge or bottom surface of the ball hitting surface (face) appears to be floating from the ground even if the protrusion of the putter body metal fitting on the green is grounded. The effect is that it is easy to take back straight back when the bottom is in contact with the ground, and it is possible to downswing with the feeling that the bottom is floating as you see it, making putting easy and applying overspin easily. There is.

Further, the top of the conical projection is easily grounded to the ground, and the resistance of the turf is small, so that the horizontality of the club at the time of takeback is more likely to occur, and complicated and extra thinking at the time of takeback is not required, and a simpler structure is obtained. Takeback is possible.
