2. Description of the Related Art Needless to say, a golf club putter is a club mainly designed for use on a green, and the shot by the putter is the most mental surface of golf shots. It depends on.

[0003] For this reason, a very large number of types of putters are provided, and it is difficult to select them. Therefore, the weight and the weight felt by a golfer are mainly based on the direction of the ball and the rolling characteristics. , The length of the shaft, the lie angle at which the head and the shaft intersect, etc. (these are referred to as selection elements in this specification).

[0004] Therefore, there has been proposed a putter head in which these selection elements can be adjusted.

[0005] For example, proposals have been made to adjust the lie angle so as to match the physique of the golfer, to match conditions such as unevenness on the green, or to match the attitude (address) to be prepared (for example, Japanese Utility Model Publication No. 2-43409). Bulletin, Jitsuhei 2
No.-36539), an L-shaped putter having features such as that the shaft does not obstruct the eyes, a sense of approach is utilized, and the sense of distance in a long pad is easily adjusted, and a switch on the extension of the shaft. T-shaped pattern that has a spot spot (core) and is easy to hit with this sweet spot
And proposals that make them compatible with each other (for example,
No. 46184) and a proposal to adjust the weight of the putter head so that the center of impact desired by the golfer matches the center of impact of the putter itself (for example, Japanese Utility Model Publication No. 57-57).
Japanese Patent Application Laid-Open No. 3-53582), a proposal in which the weight adjustment and weight distribution adjustment of a putter head can be performed in a small unit (fine adjustment) (for example, Japanese Utility Model Publication No. 3-41727),
(See, for example, Japanese Utility Model Publication No. Sho 63-30455) in which a core having an inclination angle with respect to the bottom of the ball is inserted into a putter head, and the inclination angle is changed to obtain a heavy ball type. Various proposals have been made.

[0006]

However, in each of these proposals, the adjustment in the selection elements such as weight adjustment and lie angle adjustment is almost stepwise adjustment, and as described above, the shot of the I am not fully satisfied that it depends on the mental aspects of the golfer.

Accordingly, the present invention has been devised in view of such a problem, and an object of the present invention is to adopt a columnar putter head to diversify selection elements and finely adjust the adjustment elements. It is what it was.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is an overall view of a putter head of a golf club according to an embodiment of the present invention.
Is a sectional view, (B) is a front view, (C) is a side view of (B),
FIG. 2 is a main part view of FIG. 1, (D) is a sectional view taken along the arrow B of (B),
(E) is another side view of (B), (F) is a plan view of a main part of (B), and FIG. 3 is an exploded perspective view of FIG. 1.

In the golf club putter head 1 of the present embodiment, the putter head main body 2 is formed in a columnar shape of approximately 30 mmφ so that the sole can smoothly slide on the surface of the turf.
Further, while improving the rolling property and directionality of the ball, adjustment of the plurality of selection elements, for example, loft (pattern)
It is possible to respond to a mental change of a golfer in a putter shot by making fine adjustments to the adjustment of the angle of the face with respect to the ground and the change of the position of the sweet spot.

In these figures, the putter head body 2
Is made of a material such as titanium, aluminum or the like having a low specific gravity or a material such as fine ceramics, and has an axial length of about 110 mm, and has a heel portion (shaft-side portion) 3 and a toe portion (tip portion). 4 are separated from each other, and the respective outer peripheral surfaces are formed in the same shape, and the two are connected to each other by a screw rod 5 integrally protruding inside the toe portion 4. The cover is covered by a cylinder portion 6 having substantially the same shape as the outer peripheral surface of the control portion 3 and the like. Of course, the cylinder portion 6 may be integrated with the toe portion 4, and the screw rod 5 may be integrally protruded inside the heel portion 3.

Therefore, the heel portion 3, the toe portion 4, and the cylinder portion 6 can be firmly integrated by tightening and connecting.

A thread-shaped balancer 7 carved through a female thread at the center of the threaded bar 5 is threadably engaged with the threaded rod 5 and a lock nut 8 for fixing the balancer 7. .

Therefore, the position change of the sweet spot of the putter head body 2 can be finely adjusted by screwing the balancer 7 back and forth on the screw rod 5.

In order to check the sweet spot, for example, the tip of a shaft (not shown) is lightly gripped, the putter head 1 is suspended, and the putter face 9 is
For example, hitting with a coin or the like, for example, hitting the toe portion 4 side can open the putter face 9 and hitting the hill portion 3 side can return so that the putter head 1 closes.
Since this unreturnable position is a sweet spot, it can be checked. Therefore, if the balancer 7 is positioned, for example, on the toe portion 4 side, the sweet spot can be moved accordingly. Of course, it may be determined by the positioning mark 19 as described later.

Further, the balancer 7 is made of a metal (for example, copper alloy) having a high specific gravity to form a predetermined weight of the putter head 1, and a plurality of types of balancers 7 having different specific gravities are used. If prepared, the weight of the putter head 1 can be adjusted stepwise.

If thin lead is attached to the outer surface of the balancer 7, the weight can be finely adjusted by peeling the lead with a blade. Since the balancer 7 with lead is also covered by the cylinder portion 6, there is no risk of spoiling appearance and spontaneous peeling.

The tip of the threaded rod 5 is screwed into a commercially available embedded nut 10 provided on the heel 3.
This embedding nut 10 is threaded on its outer periphery,
It is screwed and embedded in the female screw 11 cut inside the screw part 3. Therefore, the material and processing costs of the expensive heel portion 3 are reduced.

A shaft base (housing) 12 is press-fitted and fixed to the heel portion 3. This shaft base 12
Is inserted into the pattern face 9 at a predetermined angle (about 30 degrees) with respect to the pattern face 9 as shown in FIG. It is bent substantially in parallel, and a bent portion 14 is formed in a direction of about 27 ° so as to be separated from the pattern face 9 as shown in FIG.

Therefore, if the direction of insertion of the shaft base 12 with respect to the pattern face 9 is changed, a plurality of insertion holes or a plurality of shaft bases 12 are required. In the embodiment, the embedding nut 10 of the heel portion 3 is left as it is with the number of parts as it is.
On the other hand, the loft can be fine-adjusted from 0 ° to about 7 ° only by rotating the screw rod 5 of the toe portion 4 and thus by relatively rotating the cylinder portion 6.

Further, a female screw 11 is engraved in the heel portion 3 and a cavity 15 as large as possible is formed to reduce the weight and material of the heel portion 3.

The outer edge of the heel portion 3 has a radius of 10 mm.
Is formed.

Since the toe portion 4 is formed of a so-called circular head bolt and the outer edge of the head has an R of 5 mm, it is difficult to rotate the toe portion 4. Therefore, a small hexagon socket bolt 16 is screwed into the center of the outer surface, and the small hexagon socket bolt is turned by using a hexagon wrench or the like to rotate the toe portion 4 to finely adjust the loft. Or disassembled to adjust the position of the balancer 7.

The cylindrical outer diameter of the cylinder portion 6 is equal to the
Is formed slightly larger in diameter than the outer diameter of
In addition, on the front and rear sides (opposite sides), surface triangular cuts are formed over the entire length of each axis, thereby achieving inexpensive processing.

[0025] On one side of the bird, a pattern of about 15 mm
The outer surface of the pattern surface 9 is flush with the outer diameter of the heel portion 3 or the toe portion 4. Therefore, if the heel portion 3 or the toe portion 4 The direction of the ball is not impaired even if a shot is taken at the boundary between the ball and the pattern surface 9.

Since the parts other than the surface bird, especially the sole of the putter head 1 are arcuate surfaces, not only the entire surface reaches the turf surface, but also the obverse pins hitting the upper part of the ball. The influence of turf eyes is small and the direction is stable, and the resistance can be reduced by sliding on the turf surface.

Of course, if a beam piece made of a material having a high specific gravity is fitted to the arc surface of the sole on the side of the pattern face 9 by fitting it into a concave and convex key groove (fitting with an Arimizo), the existing shape is obtained. L type, T
An edge can be configured at the lower edge found in the mold, pin mold and D-shape, while still adding weight.

Further, the other surface bird 17 is made lighter in weight of the cylinder portion 6, and the other surface birds 18, 1 are also provided diagonally forward and backward.
8 is also made lighter.

The anti-pattern face 9 of the cylinder 6
On the side, as shown in FIG. 1 (B), a plurality of filaments are provided, and are used as positioning marks 19 for screwing the balancer 7 forward and backward.

Further, both ends of the cylinder portion 6 are externally fitted to concentric circular steps 20, 20 of the heel portion 3 and the toe portion 4, respectively, and fitted through O-rings 21.
Water is sealed at 1.

An oil-impregnated ring 22 is also fitted to a pair of outer peripheries of the drum of the balancer 7 to smoothly advance and retreat the balancer 7 and reinforce it as a rib on the inner surface of the cylinder portion 6 to increase a shot force. ing.

The axial position of the illustrated screw rod 5 in this embodiment is located at the center of the heel portion 3 or the toe portion 4. However, the present invention is not limited to this. 2 source
Alternatively, the circular step portions 20 of the heel portion 3 and the toe portion 4 may be eccentric.

Further, the screw rod 5 may be provided on the heel portion 3 and the embedding nut 10 may be provided on the toe portion 4.

[0034]

According to the present invention, the loft adjustment by replacing the base portion of the shaft requires a large number of parts and is stepwise adjusted. However, according to the present invention, the relative position between the heel part and the cylinder part is maintained without changing the number of parts. By the rotation, the loft can be finely adjusted, and not only the object of the present invention can be achieved, but also the heel portion, the toe portion, and the cylinder portion can be firmly integrated.

Further, the position of the sweet spot can be finely adjusted by advancing and retreating the balancer screwed to the screw rod.
In addition, since the balancer is covered by the cylinder portion, the fine adjustment is not disturbed. In addition, the screw rod is a connecting member between the heel portion and the toe portion, and is a supporting member of the balancer. Therefore, the number of parts can be reduced and the configuration can be made at low cost.
