FIG. 4 is a plan view showing a process of hitting a golf ball on both inclined sides of a concave portion of the practice golf putter according to the first embodiment of the present invention. FIG. 5 is a view taken along line F-F′ of FIG. 2. FIG. 5(a) is a view showing a process in which the golf ball hits on the both inclined sides of the concave portion and then rolls forward. FIG. 5(b) is a sectional view showing a state in which the golf ball hits on a protrusion of the concave portion and then moves upward.
A golf putter including a body 103 configured to hit a golf ball B includes a concave portion 110 formed on a front surface of the body 103 and opened forward and upward.
The concave portion 110 includes inclined surfaces 111 formed on right and left sides of the concave portion 110, and a protrusion 120 is formed at a lower end portion of a point 113 at which the inclined surfaces 111 meet each other and protrudes forward.
The concave portion 110 is formed in a closed state because a bottom portion 130 is provided at a lower end of the concave portion 110. The protrusion 120 is configured to simultaneously come into contact with the both inclined surfaces 111, the bottom portion 130, and the point 113 between the inclined surfaces 111 meeting each other.
The using example of the practice golf putter 100 according to the first embodiment is as follows.
After the golf ball B is placed on a green or a golf tee in a state in which a shaft is connected to the practice golf putter 100, the user may hold the shaft, swing the shaft while aiming at a hole-cup, and hit the golf ball G. As shown in FIG. 4, when the golf ball B simultaneously hits the both inclined surfaces 111, the golf ball may roll straight toward the hole-cup. However, when the golf ball hits one side of the both inclined surfaces 111, the golf ball may roll slantingly toward a front left or front right, thereby deviating from the hole-cup. Accordingly, for example, when the golf ball B rolls forward left, the user may embody the putting by repeating the same motion after finding out a proper point until the golf ball B goes straight toward the hole-cup while moving the practice golf putter 100 to the right in the state of FIG. 4. For example, when the golf ball B rolls forward right, the user may embody the putting by repeating the same motion after finding out the proper point while moving the practice golf putter 100 to the left in the state of FIG. 4.
In addition, when the golf ball is not hit on the both inclined surfaces 111 of the practice golf putter 100 as shown in FIG. 5(a), and a hitting height of the practice golf putter 100 is high as shown in FIG. 5(b), the golf ball B hits on the protrusion 120 and flies forward and upward. In this case, after finding out a point for allowing the golf ball to go straight toward the hole-cup while lowering a position of the practice golf putter, the user may embody the putting by repeating the same motion.
According to the present invention, since the hitting point is checked from the trajectory of the golf ball B upon hitting the golf ball B, a correct swing posture can be trained by changing a position of the practice golf putter 100 for each hitting. Accordingly, the user can quickly train the putting compared to the related art.
In addition, the bottom portion 130 serves to prevent the golf ball B from being damaged or prevent grasses on the green from being damaged, when a tip of the protrusion 120 is hit by the golf ball B. In addition, the bottom portion 130 is configured to support the protrusion 120 and prevent a shape of the protrusion 120 from being deformed due to frequent hits.

The concave portion 161 is formed in a closed state at a bottom thereof due to a bottom portion 167, and the protrusion 165 is configured to simultaneously come into contact with the both inclined surfaces 163, the bottom portion 167, and the point 164 between the inclined surfaces 163 meeting each other.
In addition, as shown in FIG. 9, a T-shape key 193 inserted into the key slot 150 is formed at a rear side of the body to replace the concave hitting portion, and a real hitting portion 190, which has a flat front surface and is inserted into the insertion groove 140 to hit the golf ball, is provided.
A rear part of the real hitting portion 190 matches the insertion groove 140 because being formed in the same manner as the rear part of the concave hitting portion 160.
In addition, an elastic portion 197 is attached to the front surface, such that the golf ball B rolls to a long distance with less force upon hitting the golf ball B. For example, the elastic portion 197 may be formed of a rubber or urethane sheet having elasticity. Alternatively, as shown in FIG. 9, a tube filled with air may also be configured. At this time, a check valve for injecting the air may be additionally added.
When the elastic portion 197 is the tube, a moving distance of the golf ball B can be adjusted according to strength of air pressure.
The using example of the practice golf putter 100 according to the second embodiment is as follows.
First, practicing the putting may be performed by mounting the concave hitting portion 160 to the insertion groove 140, in which each function and using process of the inclined surfaces 163, the protrusion 165 and the bottom portion 167 are the same as those described through the inclined surfaces 111, the protrusion 120 and the bottom portion 130 according to the first embodiment. In addition, advantageous effects are the same.
Next, when the force is applied to the concave hitting portion 160 upward or downward, the key 170 is separated from the key slot 150, such that the concave hitting portion 160 can be separated. In the above state, when the key 193 of the real hitting portion 190 is inserted into the key slot 150, the golf putter can be used for actual gaming purposes on the field.
In other words, when the golf ball B is actually hit in a state in which the real hitting portion 190 is mounted and the golf ball B rolls properly toward the hole-cup, it is confirmed that the user has trained a correct posture. Otherwise, the user may practice the hitting again after replacing the concave hitting portion 160. The elastic portion 197 can hit the golf ball B to a long distance with a less force. In particular, when the elastic portion 197 is the tube, a moving distance of the golf ball B can be adjusted according to strength of air pressure to be charged.
