Abstract

PURPOSE:To allow a player to correct his putting motion so that the track of movement of the golf putter becomes rectilinear by guiding the shaft portion of the golf putter by means of the rectilinear guide face of a guide in the form of a bar or a plate, and supporting the guide above the ground plane and horizontally by means of legs. CONSTITUTION:A pair of upper and lower guides 2 are connected together by a connecting column 10 which is supported to a pair of legs 3 via upper- and lower-stage arms 12, 13 in such a manner as freely moving in its vertical direction and having its angle of installation freely varied. The height and guiding angle of a guide 2 are adjusted to the body of a player and a putter, etc., and then the player makes a putting motion thereby guiding a shaft portion 6 to a rectilinear guide face 1; when the player makes a backswing and a follow-through, the shaft portion 6 is forced into contact with the rectilinear guide face 1, which is felt as resistance to the arms. Thereby the player can recognize his manner of putting himself and then correct his motion so that the resistance between the shaft portion 6 and the rectilinear guide face 1 is reduced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putting practice machine for making a person familiar with the trajectory of putting with a golf putter.

0002

2. Description of the Related Art A ball carried to a green is putted by a putter aiming at a hole on the green. The pleasure you get when you hit a hole over a relatively long distance with just one putt is a special feeling, and this is one of the real pleasures of golf. Therefore, when putting, the tension of concentrating on that single stroke is extremely intense. However, human motor function is not designed to trace the exact trajectory of a putt. That is, putting requires that the center of the head move accurately and linearly on an assumed putting trajectory. However, human motor function instinctively tends to move in a direction that makes the body more comfortable. Then, during putting, the backswing and follow-swing inevitably involve the head being rolled toward the player's side from the ideal putting trajectory. This causes the head to swing at the moment of impact, making it impossible to drive the ball along the ideal trajectory. In other words, the deflection of the trajectory leads to the deflection of the head, making it impossible to drive the ball straight. As mentioned above, in order for the head to run straight, both the backswing and the follow swing need to be in a straight line. Conventionally, there has been no device that corrects such a putting trajectory through the feel of the grip.

0003

[Means for Solving the Problems] Therefore, the present invention forcibly restrains the movement of the hand so that the backswing, impact, and follow-through are always in a straight line, and memorizes the movement as a sensation of the hand. The purpose of the present invention is to provide a golf putting practice machine that can perform the following functions.To achieve this purpose, the following configuration is adopted. That is, the golf putting practice machine of the present invention is formed so that the linear guide surface 1 of the guide 2 guides the shaft portion of a golf putter. The guide 2 is supported by legs 3 above the ground plane and substantially horizontally.

0004

[Operation] By adjusting the height and inclination angle of the guide 2 according to the player's body, the shape of the putter, etc., and letting the guide 2 guide the shaft of the golf putter, the practitioner's hand holding the grip can You can force the player to memorize the putting trajectory.

Embodiments Next, each embodiment of the present invention will be explained based on the drawings. FIG. 1 shows a first embodiment of the present invention, FIG. 2 is a cross-sectional view thereof, and FIG. 3 is an enlarged view of section III in FIG. As is clear from FIG. 1, in this training aircraft, a pair of upper and lower guides 2 are connected by a connecting column 10. And the connecting pillar 1
0 is supported by a pair of legs 3 via an upper arm 12 and a lower arm 13 so as to be vertically movable and to freely adjust the mounting angle. Further, the pair of legs 3 are erected on the base 11. Finally, the pair of guides 2 are supported by the base 11. Each guide 2 includes a pair of rod-shaped linear guide surfaces 1 arranged parallel to each other at an interval slightly wider than the thickness of the shaft portion 6, and a pair of partially cut-out annular enlarged portions 9.
Both ends of the linear guide surface 1 are connected to the open end of each of the linear guide surfaces 1. Note that the expanded portion 9 of the lower guide 2 has a plane that is inclined downward. The pair of guides 2 formed in this manner are connected to both ends of the four connecting columns 10 at both ends thereof.

Next, the ends of an upper arm 12 and a lower arm 13 are rotatably connected to the upper and lower ends of a pair of connecting columns 10 arranged on one side of the guide 2 via hinges 14, respectively. . An angle plate 2 is attached to the other end of the lower arm 13.
1 is fixed, and its protruding end is fitted into the closing part of the U-shaped bolt 19, and the U-shaped bolt 19 is fastened to the leg 3 via the fastener 20 so as to be vertically movable. It is configured so that the height in the vertical direction can be adjusted as appropriate. (See FIGS. 2 and 3) Next, support metal fittings 17 are provided protruding from both upper ends of the pair of legs 3, and the intermediate portion or end portion of the upper arm 12 is fitted into the support metal fittings 17. Then, the hole 15 bored in the side surface of the upper arm 12 and the slit of the support fitting 17 are aligned, and the pin 16 is inserted between them. By selecting holes 15 at appropriate positions, the inclination angle of the connecting column 10 can be changed.

[0007]

[How to use] Assemble this training machine as shown in Figs. 1 and 2, and adjust the height and guide angle of the guide 2 to suit the player's body, putter, etc. Next, putter 5
The shaft portion 6 is inserted between the pair of linear guide surfaces 1 of each of the upper and lower guides 2. For this insertion, the head 8 may be inserted through the expanded portion 9 at the end of the guide 2. The practitioner then holds the grip 27 of the putter 5 and takes a putting stance. Next, by performing a putting operation, the shaft portion 6 is guided to the linear guide surface 1. At this time, the practitioner tends to roll the head 8 toward his or her body during backswing and follow swing, but when such a movement occurs, the shaft portion 6 comes into strong contact with the linear guide surface 1, causing the arm to It becomes resistance and is felt. This allows the practitioner to understand his or her putting habits, and the practitioner performs actions such that the resistance between the shaft portion 6 and the linear guide surface 1 is reduced. Then it is head 8
This will lead to moving the ball in a straight line, allowing you to master ideal putting.

According to experiments, this putting practice machine has the following properties:
Most people feel that the head gets caught up in the practitioner's body during the backswing and follow swing mentioned earlier, and by correcting this, the swing of the ball's trajectory can be eliminated and accurate putting can be achieved. It turns out that it can be done. The reason why the expanded portions 9 provided at both ends of the lower guide 2 are inclined downward is to allow the head 8 to slip out into the expanded portions 9 when increasing the backswing and follow swing of the head 8. This was taken into consideration. Note that, generally, the head 8 does not move so much as to come out of the expanded portion 9 during backswing and follow-swing. In FIG. 2, reference numeral 29 denotes an alarm circuit, which is configured to issue an alarm when the shaft of the putter 5 comes into contact with the linear guide surface 1. In this embodiment, a conductive portion 4 is provided at the lower edge of the linear guide surface 1 on the lower stage side. One end of the alarm circuit 29 is connected to the conductive portion 4, and the other end is connected to the metal shaft portion 6. When the shaft portion and the conductive portion come into contact, an alarm circuit 2
9 is turned on, and buzzer B issues an alarm. Therefore, by practicing so that the shaft part moves accurately between the pair of guide surfaces so that the buzzer B does not issue an alarm, a more accurate trajectory can be learned. Note that this alarm circuit 29 may be installed as necessary.
