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 an angle-adjustable putter capable of setting a shaft at a desired position on a head having a sole surface constantly attached to the ground.

[0002]

2. Description of the Related Art Conventionally, many golfers have one stylized putter and practice daily to get used to the habit of the putter. However, the golfer had to kill his habit to match the putter. Most golfers did not follow the putter's habit and ignored the putter's habit and hit the ball in their own way. In addition, there are many golfers who, even if they try to adjust themselves to the habits of putters, are not familiar with their constitution, habits, or preferences.

As shown in FIG. 12, ideally, it is desirable to set the square in (a). However, there are many golfers who set an acute angle in (b) or an obtuse angle in (c). In the conventional putter, the head and shaft are integrated,
In the case of (b), the sole has a posture in which the back side opens by α °. In the case of (c), the posture is such that the face side opens by β °. Originally, the putter is designed to be 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. It is usually designed so that the ball hits the sweet spot on the face when the sole surface is evenly on the ground.

In the cases (b) and (c), the golfer hits the ball with the shaft not inclined to the ground but slightly inclined. Although the inclination is slight because it is inclined in the direction of the face angle, it looks like a large inclination for golfers who are concentrated on the putter, it is difficult to stop at the address of the putter, and the ball is hit in an uneasy state.

Further, as shown in FIG. 13, ideally, it is desirable to set the face surface at right angles to the T line and to set the sole surface on the ground evenly. Therefore, each golfer has a different θ °.

Furthermore, the face is not a T line,
There are many golfers who hold on the R line or L line because of their habits and habits. As described above, since the conventional putter has a head and a shaft integrated with each other, the face opens when held on the R line, and the face closes when held on the L line. On the ground on average. Therefore, unless a putter suitable for oneself is used, it is difficult to stop at the address of the putter, and the ball is hit in an uneasy state.

Unless the face angle and the lie angle are finely adjusted in this manner, a missed shot is ultimately caused. Due to these problems, it has been desired to develop a putter tailored to each golfer.

In the meantime, the present applicant has devised a putter described in Japanese Patent No. 2875974. This putter has a circumferential surface as a friction surface at the end of the shaft, a notch at the bottom, a screw insertion hole on the side, and a screw hole for screwing the adjustment screw up to the notch. Lumped part with an extended part having a bottom and a hole that does not screw with a screw, a screw insertion hole in which the inner surface of the lump formed in the head is in communication with a concave part that is a friction surface, and an adjustment screw inserted into the screw insertion hole It is characterized by comprising. Therefore, it is possible to adjust the head to any angle.

In the above-described putter, since the head can be adjusted in any direction in any direction, it can sufficiently cope with any golfer's tastes and habits. However, since the adjusting screw is located on the side surface of the head instead of the upper surface, it is possible to make some adjustments, but it is difficult to make fine adjustments with the shaft standing up. Therefore, it is necessary to provide an angle adjusting mechanism capable of finely adjusting the shaft while standing.

[0009]

SUMMARY OF THE INVENTION In order to solve the conventional problems, even if the shaft is slightly inclined in the face angle direction or the lie angle direction due to the golfer's preference or habit, the sole surface is required. The goal is to provide a putter that matches the golfer's address, so that it is always on the ground on average.

[0010]

In order to achieve the above object, according to the first aspect of the present invention, there is provided an angle adjusting mechanism capable of setting a shaft at a desired angle on a head having a sole surface attached to the ground. The angle of the shaft can be adjusted on the upper surface of the head. Therefore, the angle can be adjusted while the putter is standing.

A tightening nut for holding a holding portion formed near the center of the head is provided between the washer having the adjustment rod penetrated and the head, and the hole of the washer is eccentrically formed when the hole of the washer is formed. The shaft is positioned at a desired position by increasing the thickness in the direction opposite to the direction in which the shaft approaches the portion, and using the contact surface between the jaw and the constriction and / or the contact surface between the washer and the washer receiver as a friction surface. It is characterized by an angle adjustment mechanism that allows fine adjustment. Therefore, the shaft can be reliably set at a desired position.

In the invention according to claims 5 to 7, an adjusting rod having an upper end attached to the shaft and a spherical head at the lower end;
The head is loosely inserted into the hollow part provided in the head, and the screw washer that has the adjustment rod penetrated, and a bag screw member that fixes the screw washer to the washer receiver, and the top of the lower hemisphere part of the head is the bottom of the hollow part A stepped nut having a reverse female screw portion screwed to a reverse male screw portion formed on the adjusting rod, a female screw portion screwed to the male screw portion of the screw washer, and an upper portion of the stepped nut. A tightening nut that is screwed into the reverse male screw portion formed on the adjustment rod is provided.When the hole of the screw washer is eccentrically formed, the thickness of the hole in the direction opposite to the direction in which the hole approaches the edge of the washer is reduced. It is characterized in that the shaft is made thicker and that the shaft and the hollow portion or / and the washer with screw and the washer receiver are used as frictional surfaces to provide an angle adjusting mechanism capable of finely adjusting the shaft to a desired position. Therefore, the shaft can be reliably set at a desired position.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the putter of the present invention will be described. In this embodiment, an angle adjusting mechanism that can set a shaft to a desired angle is provided on a head having a sole surface attached to the ground on an average, and the angle of the shaft can be adjusted on the upper surface of the head.

An adjusting rod having an upper end mounted on the shaft and a spherical head at the lower end, and a head inserted in a hollow portion provided in the head, and the adjusting rod is fixed at a desired angle and position in the hollow portion. An angle adjusting mechanism that can finely adjust the shaft to a desired position is provided.

The hollow portion provided in the head is formed near the center of the head to maintain a space in which the head can move up and down in the hollow portion and to adjust the diameter of the head so that the adjusting rod is movable. It is desirable that the diameter is larger and the upper and lower portions are formed to be equal to or longer than the diameter.

Next, the washer is inserted into the adjusting rod, and the tightening nut is screwed into a screw portion formed on the adjusting rod to fix the adjusting rod. However, when the shaft is set up non-perpendicularly to the sole surface, , Increase the diameter of the washer hole,
Alternatively, a hole of the washer may be formed at an eccentric position. In other words, prepare the ground and vertical washers and non-vertical washers,
By making the thickness of the other one thicker than the thickness of one, and further preparing several types of non-vertical washer surfaces from gentle to steep, the washer surface and adjustment rod can always be kept vertical, The fastening of the fastening nut can be ensured.

In order to surely set the shaft at a desired position, a portion where the adjustment rod is fixedly supported on the head and a contact portion thereof are preferably formed as friction surfaces. When the adjustment rod is fixed,
The position of the shaft does not become unstable due to the resistance of the friction surface.

For fine adjustment of the shaft, the putter is set up after the upper end of the adjustment rod is attached to the shaft, and the tightening nut is loosened, so that the adjustment rod and the head are in a free state. Thereafter, the shaft may be finely adjusted to a desired position, and the tightening nut may be tightened.

Although the adjusting rod is inserted and stored in the hollow part, it is difficult to insert and store the adjusting rod in the hollow part from the upper surface of the head because the diameter of the head is larger than the diameter of the adjusting rod. Therefore, the head itself is divided vertically or horizontally around the hollow portion, and after the adjustment rod is stored, the head is reassembled or a hole is formed in the head to penetrate the head in the vertical direction. It is conceivable to insert an adjusting rod from the lower surface and then use a means for closing the opening. Alternatively, a separate body that forms a hollow portion may be provided separately from the head, and after the adjustment rod is inserted and stored, it may be set on the head.

The head assembling and the means for closing the opening are performed by a bonding method using an adhesive or a locking piece.
Alternatively, it is conceivable to form a screw portion with each other and screw-fit. In addition, regarding the mounting of the adjusting rod to the shaft, it is conceivable to form a screw portion with each other and to screw the adjusting rod together. In any case, it is sufficient that the adjusting rod is inserted and stored in the hollow portion. If the adjusting rod and the shaft can be connected, the present invention is not limited thereto, and other means may be used.

[0021]

Next, embodiments will be described in detail with reference to the accompanying drawings. 1 to 6 show a head structure of a putter according to the present invention. An angle adjusting mechanism S is provided with a through hole 3 in the longitudinal direction near the center of the head 2, and a constricted portion 4 is provided above the through hole 3.
And a washer receiver 5 is recessed at the upper end. In addition, a spherical shape larger than the diameter of the adjusting rod is provided at the lower end of the adjusting rod 10 which penetrates the through hole 3 and has an upper end mounted on the shaft 1.
A head 11 having a jaw 12 in the upper hemisphere of the sphere is provided. Further, the adjusting rod 10 is moved from the lower surface of the head 2 to the through hole 3.
After that, the bottom cover 9 having the recess 8 formed on the upper surface and having the shape matching the head 11 is set in the through hole 3. At this time, a space formed between the constricted portion 4 and the concave portion 8 in the through hole 3 is a hollow portion 6, and the hollow portion 6 is a hollow portion 6 of the head 11.
It has a space that can be moved up and down inside.

Next, the washer 15 is fitted into the adjustment rod 10 and loosely fitted into the washer receiver 5. Further, by screwing the tightening nut 17 to the screw portion 13 formed on the adjustment rod 10, the contact range between the constriction portion 4 and the jaw portion 12 and the contact range between the washer receiver 5 and the washer 15 are reduced. As the holding portion 7, they are held together from above and below.

For fine adjustment of the shaft 1, after putting the upper end of the adjusting rod 10 on the shaft 1 and setting the putter and loosening the tightening nut 17, the head descends in the hollow portion and once holds the holding portion. Since the operation is interrupted, the adjusting rod 10 and the head 2 are in a free state. Thereafter, the shaft 1 is finely adjusted to a desired position, and the tightening nut 17 is tightened again to complete.

When the shaft 1 is set up perpendicular to the sole surface, the diameter of the hole 16 of the washer 15 is increased, or the hole 16 of the washer 15 is formed at an eccentric position. That is, the washer 15 for the vertical to the ground and the washer 15a for the non-vertical are prepared. In the case of the washer 15a in which the hole 16 is formed at an eccentric position, 1
The thickness of the 15c side is made thicker than the thickness of the 5b side to keep the surface of the washer 15a and the adjusting rod 10 perpendicular at all times, thereby ensuring the tightening of the tightening nut 17. Therefore, if several types of surfaces of the non-vertical washer 15a are prepared from a gentle inclination to a steep inclination, it is possible to perform from slight fine adjustment to visual adjustment. Needless to say, as the inclination becomes steeper than the gentle inclination, the position of the hole 16 approaches one edge of the washer 15a.

If one or both of the constriction 4 and the jaw 12 are friction surfaces, the position of the shaft 1 is not unstable due to the resistance of the friction surface, and the holding portion 7 is held between the jaw 12 and the washer 15. After being held, the adjustment rod 10 is securely fixed. Similarly, in the contact surface between the washer 5 and the washer 15, if one or both of the washer 5 and the washer 15 are frictional surfaces, the fixing of the adjusting rod 10 increases the reliability.

As means for setting the bottom cover 9 in the through hole 3, means such as bonding with an adhesive or forming a screw portion (not shown) between the bottom cover 9 and the through hole 3 and screwing the same is used. Also, the adjusting rod 10 is mounted on the shaft 1 by means such as screwing a mounting male screw portion 14 provided on the adjusting rod 10 and a mounting female screw portion (not shown) of the shaft.

Next, another example of the angle adjusting mechanism S will be described with reference to FIGS.
11 will be described in detail. The angle adjusting mechanism S 'is provided with a substantially spherical hollow portion 23 extending in the vertical direction and having an open upper surface near the center of the head 22, a narrowed portion 24 provided above the hollow portion 23, and a washer at the upper end. Protrusion 25 is provided,
A screw portion 26 is screwed around the circumference. In addition, a hollow portion 2 is provided at the lower end of the adjustment rod 30 whose upper end is mounted on the shaft 11.
3 and a head 31 having a spherical shape larger than the diameter of the adjustment rod 30 and having a top portion 32 as a lower hemispherical portion of the ball. Further, the hollow portion 23 holds a space in which the head 31 can move up and down in the hollow portion 23.

Next, the washer 35 with a screw is fitted into the adjusting rod 30 and placed on the washer receiver 25. Further, in order to fix the position of the screw washer 35, the bag screw member 39 is
Then, the step nut 40 is fitted into the adjustment rod 30.

The stepped nut 40 has an inverted female screw 41 that is screwed to the inverted male screw 33 formed on the adjusting rod 30 and a female screw 42 that is screwed to the male screw 37 of the screw washer 35. are doing. The head portion 31 descends in the hollow portion 23 by screwing the reverse male screw portion 33 and the reverse female screw portion 41 and the male screw portion 37 and the female screw portion 42 with each other.
And the bottom part 27 in the hollow part 23 abuts and presses.

The washer receiver 25 has a screw portion 26 screwed around the circumference, and the screw portion 26 is sandwiched between the flanges 38 of the screw washer 35.
The bag screw member 39 is screwed into. Then, step nut 4
In order to prevent loosening of the stepped nut 40, a tightening nut 43 having an inverted female screw portion is tightened to the adjusting rod 30.

For fine adjustment of the shaft 21, a putter is set up after the upper end of the adjusting rod 30 is mounted on the shaft 21,
When the tightening nut 43, the stepped nut 40, and the cap screw 39 are loosened, the head rises in the hollow portion and stops pressing once, so that the adjusting rod 30 and the head 22 are in a free state. Thereafter, the shaft 21 is finely adjusted to a desired position, and the blind screw member 39, the stepped nut 40, the tightening nut 4
When tightening 3 again, the process is completed.

When the shaft 21 is set up non-perpendicularly to the sole surface, the diameter of the hole 36 of the threaded washer 35 is increased or
Alternatively, the hole 36 of the threaded washer 35 is formed at an eccentric position. In other words, a screw washer 35 for vertical use with respect to the ground and a screw washer 35a for non-vertical use are prepared. In the case of the screw washer 35a in which the hole 36 is formed at an eccentric position, the thickness of the screw washer 35a is made thicker on the 35c side than on the 35b side, so that the surface of the screw washer 35a and the adjusting rod 30 are always kept vertical, The tightening of the nut 40 and the tightening nut 43 is ensured. At this time, the cap screw 39 and the screw washer 3 for vertical
5 is removed, the non-vertical screw washer 35a is placed on the washer receiver 25, and the bag screw member 39 is set again. Therefore, if the surface of the non-vertical threaded washer 35a is prepared in several types from a gentle inclination to a steep inclination, it is possible to perform from a slight fine adjustment to a visible adjustment. As the inclination becomes steeper than the gentle inclination, the position of the hole 36 is changed to the screw washer 35.
Needless to say, it approaches one edge of a.

If one or both of the bottom portion 27 and the top portion 32 are friction surfaces, the resistance of the friction surfaces causes the shaft 21
After the top portion 32 has pressed the bottom portion 27, the adjustment rod 30 is securely fixed without the position becoming unstable. Similarly,
If one or both of the washer 25 and the screwed washer 35 are also frictional surfaces at the contact surface between the washer receiver 25 and the screwed washer 35, the fixing of the adjustment rod 30 will be more reliable.

The adjusting rod 30 is inserted into the hollow portion 23 of the head 22.
As described above, as described above, the head 22 itself is divided vertically or horizontally around the hollow portion 23, the adjustment rod 30 is stored, and then the head 22 is assembled again.
A means for separately providing the hollow portion 23 from the head 22, inserting and storing the adjustment rod 30, and then setting the adjustment rod 30 on the head 22 is used. The above-described means is also used for mounting the adjustment rod 30 on the shaft 21.

[0035]

The present invention is a putter that matches the address of the golfer's habit and the like, and the golfer's favorite posture of hitting the putter always changes with respect to the inclination of the shaft in the face angle direction or the lie angle direction. Adjustable so that the sole surface of the head is evenly attached to the ground. Therefore, a stable address can be obtained.

Since the angle can be adjusted on the upper surface of the head, the shaft can be adjusted while the putter is standing, and fine adjustment can be easily and accurately performed.

Since the angle can be finely adjusted in any direction, it can be surely adjusted to a desired position. Further, by making the contact portion a friction surface, the shaft can be more securely fixed, and even if vibration or impact is applied to the head, the angle once adjusted does not change, and reliability can be improved.
