In general, golf clubs are composed of a set of golf clubs to be selectively used depending on the position and pitch of the golf ball, distance to the hole cup, and the surrounding conditions, each of which is a driver, iron, putter It consists of (putter).

Among these golf clubs, putters are used to put golf balls into hole cups on the green. If the level of the striking surface is not good, the ball direction of the golf ball will show a big difference according to the minute difference. .

The putter should send the golf ball in the correct direction toward the hole cup, but there is a large difference depending on the location of the hitting point hitting the upper and lower ends of the golf ball by the unstable posture or wind when putting.

Therefore, it is important for the golfer to always keep the hitting surface of the putter head and the hitting point of the golf ball so that the center of the hitting surface of the putter head and the central portion of the golf ball are exactly positioned on one axis when hitting the golf ball.

Putting is the most important in golf as described above, but many golfers have a lot of difficulties in putting hunting. In the case of putters, the golf ball slips and cannot be sent in the desired direction. For beginners or intermediates, it is difficult to learn golf and give up easily because it is difficult to send in the desired direction using the putter.

Therefore, in order to overcome the above problems, a conventional registered utility model No. 20-0447894 "putter head with a wheel" has been proposed, looking at the technical configuration, the guide hole is formed in a rectangular in the vertical direction and the shaft is inserted, A head including a plurality of coupling holes communicating with the guide hole in a vertical direction and fixed with bolts and having springs inserted therein; bearings coupled to both ends of the shaft and having a ground contact portion coupled to an outer circumferential surface thereof; A shaft hole is formed and is inserted into the guide hole through the bearing, it is configured to include a moving member is applied to the elastic force downward by the spring.

Conventional putter head configured as described above has the advantage of improving the straightness and accuracy because two wheels are rotated at the same time on the flat green surface, but the green of most golf courses is 10-20 degrees maximum 45 depending on the difficulty It is difficult to adjust the pitching angle according to the curved green due to the wind direction or wind speed caused by rain or wind, and even when putting, only one wheel contacts the rolled green. In addition, in this case, there was a problem in that the putter head loses the direction and the accuracy is lowered.

In addition, if the golfer's height is high, you can put close to the vertical while holding the club, but if you're short, the golfer's body and the club will be put at the angle of the gap. In addition to the inferior accuracy of the putt, the putter head is shaken by the strong wind during backstroke, which causes the putting hunting.

In addition, the putting swing of the putter head is made with the rotation of the wheel when the putter head is installed on both sides as described above, but if there is sand or foreign matter or long grass on the green surface, it immediately passes. In addition, the putter head is caught in the sand or foreign matter or long grass, there was also a problem such as not making a smooth putting swing.

The present invention devised in order to solve the above-described conventional problems, the roller of the elliptical shape, the diameter of which is gradually reduced from the hem side to both ends on the bottom surface of the putter head is mounted so as to project downward from the bottom surface of the putter head, Back grooves and putting swings by rollers installed on the bottom of the putter during putting work of golfers, regardless of the angle of putting, ie the angle of inclination or the angle of inclination of the putter on the green, as the grooves are formed at equal intervals on the outer circumferential surface of the green. The purpose is to improve the straightness and accuracy of putting on the slope of the green while smoothly proceeding without jamming the green grass.

In addition, in the case of the present invention, when putting in the green using a roller formed with a plurality of grooves at equal intervals on the outer circumferential surface as described above, sand, foreign matter, grass, etc. through the plurality of grooves formed in the roller is well grooved roller The other purpose is to make the back stroke and putting swing more smoothly than when using.

In the case of the present invention, since the roller makes contact rolling along the green surface even in the strong wind blowing during the backstroke of the putter head, the putting is performed in a state in which the putting is deviated from the green surface as in the prior art. Another purpose is to be able to hit the golf ball accurately without shaking compared to the putter.

The putter head provided with the grooved roller of the present invention for solving the above object, the roller groove in the longitudinal direction on the bottom surface of the putter head, the front and rear of the putter head in accordance with the inclination angle of the green in the roller groove An elliptical roller whose diameter is gradually reduced from the center side to both ends so as to be in contact with the green surface while maintaining the pitching angle while adjusting the pitching angle is mounted to protrude downward from the bottom surface of the putter head. Forming a plurality of grooves at equal intervals on the outer circumferential surface of the sand, foreign matter, grass on the green is well drawn through the grooves characterized in that the back stroke and the putting swing is configured to be made smoothly.

According to the present invention, the back stroke and the putting swing by the roller installed on the bottom surface of the putter during the putting operation of the golfer regardless of the putting angle, that is, the angle of inclination of the putter, the inclination angle of the putter on the green, and the green inclination, are smooth without being caught on the green grass. As it progresses, it has excellent effects such as improving the straightness and accuracy of putting on the slope of the green.

In addition, when putting on the green using a putter head in which a plurality of grooves are formed at equal intervals on the outer circumferential surface, sand, foreign matter, grass, etc. are easily escaped through a plurality of grooves formed in the roller to use a roller without a groove. Back strokes and putting swings are made more smoothly than ever, resulting in better putting performance.

In addition, since the roller makes contact rolling along the green surface even in the strong wind blowing during the backstroke of the putter head for putting, the shaker is more shaken than the conventional putter performing the putting in the state of being lifted from the green surface as in the prior art. There is also an effect that can hit the golf ball accurately without.
