In addition, a groove 27 is formed on the outer circumferential surface of the wheel 3 along the circumferential direction. The groove 27 is for preventing the wheel 3 from being separated from the parallel line 18, and is preferably formed to match (correspond to) the shape of the parallel line 18.

On the other hand, as shown in Figs. 13 to 14, when the unevenness 31 is formed on the parallel track 18, the unevenness corresponding to the unevenness 31 may be formed on the outer peripheral surface of the wheel 30.

The connecting member 50 includes both ends 16 and a central portion 52 between both ends 16. The wheels 3 are rotatably installed at both ends 16 and a protrusion 5 is formed at the central part 52. Further, the central portion 52 is formed to have a height lower than that of both ends 16 and has a width greater than that of the putter heads 13 and 24.

The central part 52 is formed to have a height lower than both ends 16 in order to allow the putter heads 13 and 24 to hit the golf ball at the same height as in the actual field. If the connecting member 50 is formed in a straight line, the

putter head

13 and 24 are spaced apart from the ground by the radius of the wheel 3 and the height of the rotation shaft coupling hole 33, which is different from the actual hitting conditions in the field. In the present invention, the central part 52 is lower than both ends 16 and the

protrusions

5 and 25 are formed in the central part 52, but the

putter head

13 and 24 are the

protrusions

5 and 25. The width of the central part 52 is made larger than the width of the putter heads 13 and 24 so that it can be fastened.

The

protrusions

5 and 25 are formed to protrude from the connection member 50 and are inserted into the fastening grooves 22 and 23 of the putter heads 13 and 24. The fastening grooves 22 and 23 are formed upward from the lower surfaces of the putter heads 13 and 24.

protrusions

5 and 25 are formed to match the fastening grooves 22 and 23, and various shapes so that the

protrusions

5 and 25 and the fastening grooves 22 and 23 are not separated from each other. It can be formed as If the protrusions (5) (25) and the fastening grooves (22, 23) are separated and separated, there is a possibility that the swing movement direction of the putter head (13, 24) may deviate from the parallel line direction of the parallel line (18). to be.

The elastic member 20 is installed on the pedestal 1. 15B shows the elastic member 20 installed between the pedestal 1 and the rotating body 2, in a state in which no hit is made by the putter heads 13 and 24, that is, the wheel 3 is the rotating body ( It shows the state located in the center of 2). And, Figure 15a shows the elastic member 20 in a state in which the rotating body 2 is removed.

As shown in Figs. 15a to 15c, the central part of the elastic member 20 is fixed to the pedestal 1, and both ends are installed to elastically support the rotating body 2. To this end, the elastic member 20 is formed long along the longitudinal direction of the rotating body 2 and has a radius of curvature smaller than the radius of curvature of the rotating body 2, and accordingly, in a state slightly bent by the rotating body 2 It is preferable to apply an elastic force to the rotating body 2 in the direction of the arrow.

Meanwhile, in the drawing, one elastic member 20 is shown as having its central portion fixed to the pedestal 1 and extending to both sides, but two elastic members 20 separated from each other may be installed on both sides respectively. .

In addition, the drawings show that the elastic member 20 extends on both sides of the rotation shaft 32, but the elastic member 20 is centered on the rotation shaft 32, and the front end of one side of the rotation body 2 (That is, it may extend only in the direction of the locking projection (7)). At this time, if the wheel (3) is in the center position of the rotating body (2), both ends of the rotating body (2) are at the same height from the pedestal (1), and the wheel (3) runs between the ends along the parallel track (18). In response to the movement, the elastic member 20 applies a pushing elastic force and a pulling elastic force to the rotating body 2.

15D shows a case where the putter heads 13 and 24 are hit. In a state in which the putting exerciser is arranged so that the parallel track 18 faces the target point, the hitting surface of the putter heads 13 and 24 forms a vertical plane with the direction toward the target point.

At this time, the mounting part 4 moves along the parallel line 18 together with the

putter head

13 and 24, and accordingly, the rotating body 2 rotates about the rotation shaft 32, the elastic member ( 20) applies an elastic force in the direction of the arrow to the rotating body 2 so that the parallel track 18 and the wheel 3 are in close contact, and the mounting part 4 and the

putter head

13 and 24 are in close contact. As a result, the swing of the

putter head

13 and 24 proceeds along the parallel track 18, and the hitting surface of the

putter head

13 and 24 continuously maintains a certain angle toward the target direction before, during and after the hit. Will be maintained.

As described above, the golf putting exerciser according to the present invention strikes the golf ball with the hitting surface of the putter heads 13 and 24 and sends it to the target point. After setting so that it is on a vertical plane, the hitting surface is maintained at the set angle before, at the moment of hitting, and after hitting, so that the motion of hitting the ball can be repeatedly practiced.

The elastic force of the elastic member 20 may be increased or decreased as needed. For example, as shown in FIG. 16, by installing the adjusting screw 35 under the elastic member 20 and adjusting the height of the adjusting screw 35, the elastic force of the elastic member 20 can be adjusted.

17 is a cross-sectional view showing a modified example of the elastic member 20a. The elastic members 20a are springs installed on both sides of the rotation shaft 32, respectively. The springs 20a are respectively installed on both sides of the rotation shaft 32 to apply an elastic force to the rotation body 2 to push the rotation body 2 upward.

In place of the elastic spring 20a, an elastic plate such as a leaf spring may be installed between the pedestal 1 and the rotating body 2.

On the other hand, in the present invention, the fastening of the

putter head

13, 24 and the mounting part 4 is due to the fact that the

protrusions

5 and 25 are inserted into the fastening grooves 22 and 23 of the

putter head

13, 24. Made by Therefore, the fastening grooves 22 and 23 must be formed on the lower surfaces of the putter heads 13 and 24.

However, when the fastening auxiliary unit is used, a conventional putter head without fastening grooves 22 and 23 can also be fastened to the mounting portion 4. As shown in Figs. 19 to 21, the fastening auxiliary unit 41 includes a body and a fastening means for fastening the body to the putter heads 13 and 24.

The body is a flat plate including a groove 37 and a pedestal 48. The protrusion 5 is inserted into the groove 37 to be fastened. In addition, the support 48 is a portion protruding in an L shape at the lower end of the body, and supports the putter heads 13 and 24.

The fastening means includes a ring 38 installed on the body and an elastic strap 36 fastened to the ring 38. Rings 38 are installed on one side of the body, preferably on both sides of the body. In addition, the elastic strap 36 is a strap having elasticity, and as shown in FIGS. 20 and 24, the putter heads 13 and 24 are fixed to the body while both ends thereof are coupled to the ring 38. .

The elastic strap 36 can be made in a variety of structures. For example, as shown in FIG. 25, the elastic strap 38 may be made in the form of a net.

On the other hand, Figure 22 is a modified example of the fastening auxiliary unit, the fastening auxiliary unit 42 is different from the above-described fastening auxiliary unit 41 in that the groove 45 is formed on the side of the body. As shown in FIG. 23, the protrusion 5 is inserted between the hitting surface of the putter head 13 and the side surface of the body (ie, the groove 45) and fastened.

26 to 27 are another modified example of the fastening auxiliary unit, the fastening auxiliary unit 43 of FIG. 26 has only one groove 46 formed inside the body, and the fastening auxiliary unit 44 of FIG. 27 is a fastening groove It is differentiated from the aforementioned fastening auxiliary units in that only one 47 is formed on the side of the body. The method of coupling the fastening

auxiliary units

43 and 44 with the putter head is the same as described above.
