Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf putter having a structure in which the shape of a club can be freely changed, and its parts and equipment.

[0002]

2. Description of the Related Art In a conventional golf putter,
The shape of the club is generally fixed. There is also a golf putter having a structure in which the shape of the club is constant, but the angle of the ball striking face is variable. (For example, Japanese Patent Application No. 2-6
(See No. 6019)

[0003]

In the conventional golf putter, even if the hitting surface can be changed, the shape such as the angle of the shaft or the grip and the length of the shaft cannot be changed with respect to the longitudinal direction of the head. However, there is a problem in that the golfer must make a custom-made modification even if he / she wants to change the shape to his or her own preference. Furthermore, in order to find out the shape of the golf putter that matches the individuality of the golfer's own putt, there is a problem that it is necessary to purchase a plurality of golf putters or modify them into a plurality of kinds of shapes.

According to the present invention, various shapes can be easily changed in the longitudinal direction of the head with one golf putter. Furthermore, the aim is to make it easy to find a shape that matches the individuality of the golfer's own putt.

[0005]

In order to achieve the above object, in the golf putter of the present invention, the angle with the shaft with respect to the longitudinal direction of the head (regardless of the face surface, the head and the shaft of FIG. 5). (See the angle with and) can be freely changed by the variable portion, and further, the variable portion can be locked.

Further, the structure is such that the angle and arrangement of the shaft and the grip can be freely changed by the variable portion and the variable portion can be locked.

The positions of the variable parts of the head and the shaft and the shaft and the grip may be between the shafts, but the positions around the connecting parts of the head and the shaft and the shaft and the grip are preferable.

Further, the structure is such that the expansion and contraction of the shaft can be freely changed by the variable portion and the variable portion can be locked. Further, in order to change the arrangement of the grips, a structure for rotating an outer shaft and an inner shaft, which will be described later, in opposite directions is provided.

For a reason to be described later, when the head and the shaft are locked at a substantially right angle, the shaft and the head can be accurately and easily moved like a pendulum of a timepiece. It is preferable to attach a rotating device to the.

Further, in order to move the shaft like a pendulum of a timepiece, it is preferable to attach a handle to the upper part of the shaft.

[0011]

In the golf putter constructed as described above, the shape can be freely changed in the longitudinal direction of the head. That is, from a different point of view, it can be formed into various shapes by changing the angle of the head or grip in the longitudinal direction with respect to the shaft, and the expansion or contraction or rotation of the shaft, and can be used by locking at that position.

When a rotating device or a handle is attached and a pad is put along the rotation axis, it is possible to hit a ball accurately like a pendulum of a timepiece.

The embodiment shown in FIG. 4 is an enlarged cutaway sectional view of the variable connecting portion with the inner shaft 3 which is inserted into the hollow portion 13 of the outer shaft 2. The outer shaft 2 and the inner shaft 3 are locked (fixed) by bolts 14. A hard rubber 15 is fixed to the tip of the bolt 14.

With the above-described structure, the expansion and contraction of the entire shaft can be freely changed by the variable portion, and the shaft can be locked (fixed) at a desired length. Further, the outer shaft 2 and the inner shaft 3 can be rotated in opposite directions.

The embodiment shown in FIGS. 5A to 5H is a modification of the embodiment of the golf putter in which the shape of the club is freely variable. 5 (a) to 5 (e) are side views of the golf putter, and FIGS. 5 (f) to 5 (h) are plan views seen from above.

Various modifications of the golf putter are formed by changing the angle between the head and the shaft and the angle between the grip and the shaft, or by rotating or expanding or contracting the outer shaft and the inner shaft, respectively.

FIG. 5C shows a golf putter having a shape in which the inner shaft 3 and the outer shaft 2 and the grip 1 are positioned substantially at right angles to the longitudinal direction of the head 4. In this case, it is possible to use by locking all the connecting portions, but by removing the hard rubber rings 10 and 10 (see FIG. 3 (a)) at the connecting portion between the grip 1 and the outer shaft 2,
By making it a connecting portion between the grip 1 and the outer shaft 2 in FIG. 1, it is possible to rotate and hit a ball like a pendulum of a timepiece.

In this case, the grip 1 can be held with one hand and the upper part of the outer shaft 2 can be hit with the other hand like a pendulum of a timepiece. In this case,
It is preferable to have the handle 16 of (c). Further, it is optional to provide the handle 16 at a position where it is easy to hit a ball and also in FIG. 5 (d).

FIG. 5 (e) shows a golf putter in which the inner shaft 3 is deeply inserted into the outer shaft 2 having a hollow portion to shorten the entire shaft.

FIG. 5 (f) is a plan view of FIG. 5 (b) as seen from above by the golfer.

FIG. 5 (g) is a plan view of a golf putter having a shape in which the arrangement of the grip 1 is changed. That is, the grip 1 is arranged at a position inclined laterally when viewed from a plane. [Refer to the difference from the arrangement of the grip 1 in FIG. 5 (f)]
This structure is formed by rotating the outer shaft 2 and the inner shaft 3. Alternatively, the shaft may be rotated at each variable connecting portion (not shown). It is formed by the golfer's liking in order to hit the ball accurately.

In the shape of FIG. 5 (h), the shaft is positioned at right angles to the longitudinal direction of the head, and further, the grip 1
6 is a plan view of a golf putter arranged in the same manner as the grip 1 of FIG. 5 (g).

Since the golf putter has the structure as described above with reference to FIGS. 1 to 5, the golfer's favorite shape can be freely changed and formed. It should be noted that it is preferable to provide a scale plate or the like at the connecting portion at a variable position for confirmation before and after use.

In the prior art, a golf club with a variable striking face becomes a putter when the striking face (face) is made substantially at right angles to the ground, and the striking face (face) changes its angle with respect to the ground and faces upward. When you open the face, the ball you hit will fly away from the ground. Therefore, the angle at which the sphere flies with respect to the ground changes depending on the angle at which the face opens, so this is a proposal using the angle of the face.

Therefore, it is completely different from the proposal of the present invention. In other words, the golf putter of the present invention is a golfer's own, suitable shape for hitting a ball straight (accurately) to the target, not to change the quality of the putt for multiple purposes or to fly. The purpose is to find a conforming putter that can be easily deformed without separately modifying and modifying the golf putter.

[0033]

It is said that all swings in clubs other than golf putters, such as drivers and irons, have their respective basic patterns. However, it is even said that the putter putt has no basics. Therefore, the golfer himself has various hitting (putting) methods. In addition, it is said that a putter that suits the golfer himself is good because it does not require a flight distance.

It goes without saying that the golfer's own method of hitting (putting) also has a peculiar habit because the addresses are different from each other, and a putter suitable for that person is good. For that purpose, it is preferable to find a golf putter having a shape suitable for the individuality of the golfer's own putt.

In the golf putter of the present invention, the grip and head angles are changed with respect to the shaft, and the outer shaft and the inner shaft are respectively rotated in reverse to change the grip arrangement and the shaft is expanded and contracted. By doing
It is possible to easily change and form various shapes with one putter.

For example, it is preferable that the head and the shaft are formed substantially at right angles and putt like a pendulum of a timepiece.
In the conventional putter, the grip is connected to the shaft in a substantially straight line, so it is difficult to swing, and when the shaft is hit with one hand, the other grip moves in the opposite direction at the same time and the pressure load is large. , There is a risk of shaking and it is difficult to put accurately. However, in the golf putter of the present invention, the grip is set at a position where it is easy to grasp,
Moreover, by removing the hard rubber ring and rotating the shaft along the rotation axis with the handle according to preference, it is possible to further reduce the pressure load on the grip and make an accurate hit.

Furthermore, if the shaft is shortened as shown in FIG. 5 (e), it is possible to hit more accurately.

Further, as shown in FIGS. 5 (g) and 5 (h), it is possible to change the arrangement of the grips so that a stable grip can be adjusted to each golfer's taste.

As shown in FIG. 5 (a), there is a famous professional who puts the shaft with the shaft close to the ground. However, in the case of a golf putter having a general shape, the result is not as shown in FIG. 5A, and the tip of the bottom of the head stands up against the ground, which makes it difficult to hit. Also, when the shaft is perpendicular to the ground as shown in FIG. 5C, the rear part of the bottom of the head also stands up against the ground in the case of a putter having a general shape. However, the golf putter of the present invention has no problem because the angle between the head and the shaft can be adjusted.

Furthermore, a set of detachable assembly parts (kit) is provided, which is convenient for carrying around for practice during travel and can be sold as a kit. For golfers who are enthusiastic about research, the fun will increase.

Further, when the shaft is remodeled by changing the grip angle or arrangement, it is difficult to insert the grip into the golf bag from the tip of the grip. However, in the golf putter of the present invention, the grip can be locked substantially linearly with respect to the shaft and can be easily stored in the golf bag if the position is confirmed by the scale.

The above description of the embodiments is intended to explain the present invention, but does not limit the invention described in the claims or reduce the scope thereof. Further, it goes without saying that the configuration of each part of the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical scope described in the claims.

For example, the configuration of the device having a structure capable of changing the shape of the club and locking the variable portion and the position thereof, the rotating device between the grip and the shaft, and the handle device on the upper part of the shaft are limited to the embodiments. Of course, it goes without saying that various devices can be configured. For example, various configurations can be made by combining components other than hard rubber, nuts, and bolts, and a cylinder or the like can be used as a rotating device. The shape of the handle may be the shape of a grip.

Further, it goes without saying that a golf putter component constructed for the purpose of proposing the present invention and a device related thereto are also within the scope of the present invention.
