[Technical field to which the invention belongs]

 The present invention relates to a golf putter, and more specifically, when pushing a golf ball, the force and the moving direction of the ball can be easily controlled, the probability of hole-in can be increased, and the life of the golf putter can be improved. It relates to a golf putter that is long, practical and convenient.

[0002]

[Prior art]

 A general golf putter that has been conventionally used is as shown in FIG. 1, and includes a rod (shaft) portion 2 and a head portion 3. The rod portion 2 provided with the grip 2G is connected to the irregular elliptical head portion 3 by the lock fixing means by the head fixing portion 4, and the putter surface (limited to the central axis 3A of the head portion 3 ( Or, the golf ball is struck and pushed out so as to make a hole-in along the line of motion of the golf ball by 3F (also called “club face”).

Further, in order to facilitate the hole-in, the center of gravity 3G of the putter surface 3F is provided so as to be toward the center of the golf ball, and the center axis 3A of the head portion 3 and the line for pushing out the golf ball are The golf balls are formed so as to intersect with each other vertically, and with this, the golf ball is propelled with a proper thrust and a correct direction and is made into the hole.

Further, the grip 2G is provided with an aiming surface 2F which is perpendicular to the central axis 3A of the head portion 3 so that a fixed position of the grip when the user pushes out the ball is obtained. The axis 3A and the thrust line of the golf ball are configured to be perpendicular to each other.

However, since the putter surface 3F is too long due to the irregular elliptical shape of the head portion, it is difficult to hit the golf ball so that the center of gravity 3G accurately hits the golf ball. When it hits the ball, its thrust is either too great or insufficient, resulting in the golf ball crossing the hole or stopping in front of the hole.

At the same time, since the head portion is not formed symmetrically on both sides of the rod portion 2, the center of gravity 3G of the putter surface 3F is not located on the axis 2A of the rod portion 2, and the center of gravity 3G is the axis line. It will have a kind of inertial torque for 2A. Therefore, when the putter surface 3F pushes out the golf ball, the putter surface 3F is easily affected by the inertia torque, the putter surface 3F is twisted with respect to the axis 2A, and the putter surface 3F is distorted. Further, the center line 3A of the head portion 3 and the thrust line of the golf ball cannot be kept perpendicular, and as a result, the thrust ball deviates from the thrust line of the golf ball and cannot be hole-in.

Further, since the rod portion 2 and the head portion 3 of these conventional golf putters 1 are integrally connected by the lock fixing means of the head fixing portion 4, either the rod portion 2 or the head portion 3 is connected. If a problem such as damage or failure occurs in the product and it becomes unusable, the fixed connection structure of the lock fixing means must be destroyed, and the defective part must be replaced and fixed again. Therefore, the cost is very high. Otherwise, not only the parts that have not failed must be disposed of, but it is not only economically wasteful, but also the spirit of “waste utilization” and “recycling”, which are the concepts of environmental conservation. Become.

Further, the grip 2G is damaged due to wear when it is used for a long time. In that case, this can be taken out and replaced with a new grip 2G, but if it is replaced by hand and sticks to the rod part 2, it is difficult to position the aiming surface 2F accurately. As a result, the aiming surface 2F cannot be held perpendicular to the central axis 3A, and when the grip 2G is gripped, the putter surface 3F is distorted, and the accuracy of the direction of the golf ball ejected is lost.

【Example】

 Next, the configuration of the present invention will be described with reference to specific examples. 2 and 3 are views schematically showing an example of the golf putter of the present invention, and FIG. 3 is a side view thereof when FIG. 2 is a front view of the golf putter. As shown in these drawings, a golf putter 10 of the present invention comprises a rod portion 20 provided with a grip 20G at one end (upper end) and a columnar head provided at the other end (lower end) of the rod portion 20. And a part 30. The axis 20A of the rod portion 20 is orthogonal to the pillar-shaped axis 30A of the head portion 30 at the midpoint of the axis 30A. As a result, the outer shape of the head portion is formed symmetrically with respect to the axial line of the rod portion. In the head portion 30, a putter surface (club face) 30F is formed on the end surface of the columnar shape in the axial direction.

The shape of the head part may be a columnar shape, but from the point of symmetry with respect to the axis of the rod part, a regular polygonal shape or a columnar shape having a circular cross section is preferable, and a cylindrical shape is particularly preferable. .

When the shape of the head portion is cylindrical, the diameter of the circle of the cross section of the columnar shape and the length of the cylindrical shape of the head portion are not limited, and are dimensions that allow a golf ball to be hit. If

It is preferable to provide a partial flat surface 20F, which functions as an aiming surface, at the end of the grip, similarly to the one described in the above-mentioned prior art.

The rod portion and the head portion may be inseparable and integrally formed, but as shown in FIG. 4, they are preferably connected by a detachable connecting means 40. Good Thus, even if a problem such as damage or failure occurs in either the rod portion or the head portion, only that portion can be easily replaced.

As a connecting means for detachably connecting the rod portion to the head portion, a structure in which the tip portion of the rod portion is inserted and fixed in the head portion is preferable. Among these connecting means, as shown in FIG. 4, a male screw 42 is formed on the tip portion of the rod portion 20, and a female screw 43 is formed on the head portion for screwing this into the connecting means 40. Therefore, the structure in which they are connected is particularly preferable. In this case, the hole or female screw formed in the head portion for inserting the tip portion of the rod portion into the head portion is such that the axis of the rod portion corresponds to the columnar axis 30A of the head portion 30 with respect to the axis 30A. It is formed so that it can be orthogonal at the midpoint.

The female screw formed in the head portion may be formed in the through hole or the blind hole.

It is preferable to provide a fixing means in order to securely fix the both ends of the rod portion inserted in the head portion. An example of the fixing means is a structure in which a screw such as a set screw is screwed from the surface of the head portion toward the rod portion inserted into the head portion. The set screw makes it possible to maintain the tip of the rod part inserted in the head part, which is a preferable detent when the rod part is screwed into the head part for connection.

Further, a female screw 45 for a set screw is formed on the head portion. The female screw 45 is preferably provided so as to be orthogonal to both the columnar axis of the head and the axis of the head. As a result, the set screw 44 is rotatably rotated to vertically contact the rod axis 20A and the head axis 30A.

The head of the set screw is not limited to having a slot or a hexagonal hole, but a slot having a special tool is preferable.

When the rod portion is screwed into the head portion for connection and a set screw is used, the portion of the entire length of the male screw formed at the tip portion of the rod portion where the tip portion of the set screw hits the screw It is preferable to form a smooth section that is not formed and use it as a portion that receives the tip of the set screw. That is, as shown in FIG. 4, the male screw 42 has a structure in which it is divided into two stages in the longitudinal direction, and a smooth fixing surface 42F which is not threaded is interposed in the middle thereof. With this structure, when the set screw 44 is rotated and tightened, the tip of the set screw 44 comes into contact with the smooth fixing surface 42F, and the male screw 42 of the rod portion 20 is fixed in the female screw 43 of the head portion 30. Even if tightened firmly, the tip of the set screw only bites into the flat fixing surface 42F, and the thread of the male screw of the rod portion is not crushed.

When the rod portion 20 and the head portion 30 are separated, or when the angle of the aiming surface 20F with respect to the pattern surface 30F is finely adjusted, the set screw 44 is loosened. By releasing the tightly fixed state between the male screw 42 of the rod portion and the female screw 43 of the head portion, the rod portion 20 is rotated to be removed from the head portion 30, and the rod portion 20 is rotated to rotate the shaft. After adjusting the angle to a desired angle, the set screw 44 is rotated and tightened so that the male screw 42 and the female screw 43 are brought into close contact with each other and fixed.

As shown in FIG. 5, it is preferable that an aiming portion 31 having a length equal to that of the head portion 30 is formed in the upper side region of the side surface of the head portion 30. The shape of the aiming portion is preferably a long strip shape along the longitudinal direction of the head portion so that the image is well retained by the user. In addition, the sighting portion may be colored or may be a three-dimensional display with unevenness. The example of FIG. 5 is an example in which a long strip shape along the longitudinal direction of the head portion is expressed by a concave portion. With such an aiming portion, when the user pushes out the golf ball, the user can easily grasp the course of the ball and aim it easily.

The putter surface 30 F may be formed on only one end surface of the head portion in the axial direction of the columnar shape, or on both end surfaces, but it is formed on both end surfaces at the same time, and both end surfaces of the head portion 30 are formed. Also, by making it a putter that can be used as a club face, it will be more convenient and practical to use.

On the putter surface 30F, it is preferable to form an uneven pattern that causes a frictional action. The pattern of the uneven pattern is not limited. The example of FIGS. 3 and 5 is a preferred example of this uneven pattern, and is an example of the case where the uneven pattern 32 is formed in a striped pattern. When the golf ball is pushed out by this uneven pattern, the frictional force that the golf ball instantaneously adheres to the putter surface 30F is held at the moment of impact of the putter surface with respect to the golf ball, and the slip phenomenon due to the impact occurs. The phenomenon that the pushing direction is shifted is suppressed, and the golf ball is pushed to the planned course.

The materials used for the rod portion and the head portion are not limited, and materials used for conventional golf putters may be used. Furthermore, the head portion may be freely selected from wood, metal, resin, or a combination thereof.

The above-described embodiments are examples of specific implementation of the present invention, and do not limit the scope of implementation of the present invention. Any changes or modifications made under the spirit and principle disclosed in the present invention shall be included in the claims of the present invention.

[Effect of the invention]

 As is clear from the above description, the present invention has the following excellent effects. 1. The golf putter of the present invention has a long columnar head portion, and the head portion forms regular symmetry on both sides of the rod portion. Therefore, the twisting torque generated by the irregular shape of the head, which is seen in the known putter, and the phenomenon that the putter surface is displaced do not occur. Therefore, the direction in which the golf ball is pushed can be accurately grasped, and the probability of hole-in increases.

2. In the golf putter of the present invention, the end surface of the longitudinal axis of the long columnar head portion is used as the putter surface, so that the head surface of a known putter is too long and it is not easy to impact the golf ball with its center of gravity. In addition to eliminating the disadvantage, the emphasis is limited to the axial end face of the head portion in the longitudinal direction, and the axis of the head portion and the pattern line are easily aligned. For this reason, the force of impact can be controlled easily, and the accuracy of hole-in can be increased.

3. In the golf putter of the present invention, the rod portion and the head portion are detachably connected. Therefore, when one of them is damaged, the damaged one can be easily replaced. This not only prolongs the life of the product, but also fits the idea of "recycle" for environmental protection.

4. With the configuration in which the rod portion and the head portion are detachably connected, it is easy to replace the rod portion and the head portion, and by rotating the male screw and the female screw, the rod of the head portion is rotated. The angle with respect to the part can be adjusted, and the relative positions of the putter surface and the sighting surface of the grip can be adjusted at any time. Therefore, it is possible to reduce the possibility of distortion in the direction of pushing out the golf ball. In addition, the length of the entire rod portion can be adjusted by adjusting the amount of insertion of the rod portion with respect to the head portion. Therefore, the user's need can be met, and the utility of the present invention can be enhanced.

5. When putting on the green, anyone who is familiar with golf can understand that in order to push the golf ball in the correct direction and put it in the hole, the putter surface and the golf ball must be pushed. You must concentrate all your nerves so that you keep them perpendicular to the lines you put out. Therefore, the nerves and attention used for this are much larger than those of swings other than the green. For this reason, some of the holes in the first half used too much mental force to go into the hole, and after that, the attention was distracted due to fatigue, and the golf course could not be held accurately. You

However, since a long strip-shaped sight is provided on the head portion of the putter of the present invention, when the player performs putting, the sight of the sight is visually observed due to the residual phenomenon of sight and the golf ball is pushed. The straight line in front of the golf ball can be easily grasped, and the line of motion when the head is pushed out can be easily matched with the line of movement of the golf ball. Therefore, it is possible to reduce the concentration of attention required during putter by half, or further reduce it. Therefore, not only can the golf ball be propelled in an accurate direction, but also fatigue due to concentration of attention can be reduced and concentration of attention can be continued. This will greatly increase the probability of hole-in.
