Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head structure of a putter whose angle is adjustable so that a shaft having a sole surface evenly attached to the ground can be set with a shaft at a desired angle.

[0002]

2. Description of the Related Art Conventionally, a single putter has been standardized.
Various people are practicing to fit the putter and are trying to get used to the "habit" of the putter. However, in order for the human to match the putter, he must kill his own "habit". Most people obediently try to get used to the putter. However, there are some people who do not follow the putter, rebel, ignore the putter's "habit", and use it in the ego style. Also, even if you try to match yourself with the putter's "habit", there are people who can't get used to it due to their physical constitution, "habit", and taste. Due to such problems, the development of putters suitable for human beings has been desired. In it, a putter that fits some humans was devised. FIG. 6 shows an example. (See, for example, Japanese Patent Laid-Open No. 5-76622) FIG. 6 shows a putter posture perpendicular to the line for hitting a putter, and the lie angle θ can be adjusted with respect to the shaft 1 at the time of addressing. Certainly, the putter is designed to match the lie angle of each person. However, this structure is an adjustment of the lie angle θ on the surface perpendicular to the line during the addressing of the putter, and it has not yet been possible to completely solve the desired putter suitable for humans. In fact, the problem shown in FIG. 7 remains. That is, this is a case where the face angle ε is different due to the preference at the time of addressing. Most golfers set up in the square in (a). However, some people hold it at an acute angle (b) or an obtuse angle (c). Since the head and the shaft are integrated, in the case of (b), the back side of the sole is in a position to open by α °. Further, as shown in (c), some people take a posture in which the face surface side opens by β °. Originally, the putter is designed to hit in the standard posture of (a), and the sole surface in the case of (a) is designed to be installed horizontally on the ground. Usually, the ball is designed to hit the sweet spot of the face when the sole surface is on the ground evenly.
In the cases of (b) and (c), the golfer hits the ball with the sole surface slightly inclined. Since the head is inclined in the width direction, the inclination is slight, but for golfers who concentrate their nerves on the putter, it looks like a large inclination, and when the putter is addressed, it is difficult to stop and hit the ball with anxiety. Become. Therefore, a miss shot is likely to occur. If such adjustment of the face angle is not solved, it can be said that humans still have to adjust to the putter.

The present invention has been made in view of the conventional problems, and an object thereof is to putters that match addresses of all human tastes, such as "habit", that is, humans without focusing on face angles. It aims to provide matching putters.

[0004]

In order to achieve the above object, the putter according to the present invention has a golfer's preference and
Even if the shaft of any putter such as "habit" is used,
An angle adjustment mechanism was provided in the head so that the sole surface always contacts the ground evenly and the ball is always hit at the sweet spot.

The angle adjusting mechanism uses a friction surface on the end surface of the shaft, a notch on the lower side, a screw insertion hole on the side surface, and a screw hole for engaging the adjusting screw up to the notch. , The extended portion from the notch has a bottom and is a hole that is not screwed into the adjusting screw, the concave portion in which the inner surface of the massive portion formed in the head is a friction surface, and one side surface of the head communicates with the concave portion It is composed of a screw insertion hole and an adjusting screw which is inserted from the screw insertion hole and is screwed into the screw hole to be expanded in the recess through the notch of the block.

[0006]

The ball will always hit the sweet spot because the sole surface of the head is evenly attached to the ground regardless of the angle of the shaft.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the first embodiment. A lump portion 2 is formed at an end of the shaft 1, and a lower portion of the lump portion 2 is
A notch 3 is formed, and the block portion 2 is bifurcated through the notch 3. The entire peripheral surface of the lump portion 2 forms a polyhedron that is a friction surface, and abuts and fixes the inner surface of the recessed portion 7 of the head described later. Reference numeral 4 is a screw hole that is screwed into an adjusting screw described later. Screws are engraved up to the notch 3, but a simple hole 5 into which the adjusting screw 10 is not screwed is provided in the portion extending coaxially from the notch. Reference numeral 7 denotes a concave portion formed on the upper surface side of the head 6 and having a friction surface on the inner peripheral surface thereof, and the block portion 2 is inserted into the recess 7 by reducing the notch 3 and the block portion 2 as shown by a broken line. Reference numeral 8 denotes a screw insertion hole for inserting an adjusting screw formed on the side surface of the head 6, which communicates with the recess 7. The screw insertion hole 8 is shaped like a mortar as shown in the figure because the angle of the shaft 1 is changed and the screw hole is changed accordingly, so that a screw can be inserted and tightened at any time even if it rotates a small amount. It has been expanded. Reference numeral 10 is a screw, and the head is grooved so that it can be turned by a screwdriver (not shown). Except for the tip, the screw is engraved.

The mounting of the shaft on the head of the present invention is
When the lumped portion 2 of the shaft 1 is shrunk into the recessed portion 7 of the head 6 as shown by the broken line and is inserted from the upper surface of the head 6, the notch 3 returns to its original state due to the elastic force, and the lumped portion 2 projects into the recessed portion.
It becomes difficult for the head 6 to come off easily. Next, adjusting screw 1
0 is inserted into the screw hole 4 of the lump portion 2 from the screw insertion hole 8 and is inserted while rotating the adjusting screw 10 with a screwdriver, the adjusting screw 10 advances while screwing with the screw hole 4, and passes through the notch 3. Then, it further advances inside the hole 5 and hits the bottom portion 5a of the hole 5. Even if it hits, when the adjusting screw 10 is further turned, the notch 3 is expanded. When the notch 3 is expanded, the polyhedron on the peripheral surface of the lump 2 comes into contact with the friction surface on the inner peripheral surface of the recess 7 and is fixed by friction on both surfaces. When the adjusting screw 10 is turned until it does not turn, the shaft 1 is fixed to the head 6 in its relative position. Since the adjusting screw 10 is screwed into the screw hole 4 of the block portion 2, the fixing state is maintained unless the adjusting screw 10 is turned in the opposite direction. Of course, there is no need to worry about loosening when using the putter. When adjusting the angle of the shaft 1 with respect to the head 6,
On the other hand, adjust the shaft 1 to the golfer's habit and favorite angle (any angle not limited to face angle, lie angle),
Maintaining the shaft 1 at that angle, the head 6 is
By tightening the set adjustment screw 10 with a screwdriver, it can be fixed at a desired angle. Further, when the screw is loosened, the tip of the adjusting screw 10 is disengaged from the bottom 5a of the hole 5, the notch 3 is reduced accordingly, and the lump 2 is disengaged from the inner peripheral surface of the recess 7 to allow the angle adjustment. . The friction surface of the lump and the friction surface of the inner peripheral surface of the recess may be shot blast.

FIG. 2 shows a second embodiment of the present invention. The structure is such that the concave portion 17 is provided on the sole surface 9 side of the head 6 and is cut out on the upper surface of the head to form a hole. In the case of this configuration, the shaft 1 is inserted from the sole surface side of the head 6 and pulled up on the head 6. Others are the same as those in the first embodiment and will not be described.

FIG. 3 shows the third embodiment of the present invention in which the block portion 2 of the shaft 1 is inserted from the recess 27 formed on the side surface (back surface 13) of the head 6. In the figure, 14 is a guide groove of the shaft 1, and 15 is a cover that covers the guide groove 14 and the recess 27. Others are the same as those in the first embodiment and will not be described.

FIGS. 4 and 5 show a fourth embodiment of the present invention in which the head is vertically divided into two parts, and the block portion 2 of the shaft 1 is sandwiched from both sides. As shown in the figure, the two divided heads 6a and 6b are provided with recesses 7a and 7b for accommodating the lumped portion 2 of the head 1, respectively, and adjustment screws 10 are provided on the side surfaces.
Insertion holes 8a, 8b are provided so as to communicate with the recesses 7a, 7b. Further, on both mating surfaces of the heads 6a, 6b, a fitting portion 18a for integrally joining the heads 6a, 6b is formed.
25a, 18b, and 25b are formed. Further, a sole plate 26 to be attached to the sole surfaces 9a and 9b is provided. Others are the same as the first embodiment. Assemble the adjustment screw 1 in advance.
The lumped portion 2 of the shaft 1 into which 0 is screwed is inserted into the recessed portion and the screw insertion hole of one head, and the fitting portions of both heads are coated with an adhesive and fixed by fitting. Subsequently, the sole plate 26 is coated with an adhesive on the sole surface and bonded to each other to complete the process as shown in FIG. This structure is easier to work than other examples.
