Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a putter practice device that is small, lightweight, and convenient to carry, allowing easy putter practice even indoors.

[Background technology and its problems]

For many amateur golfers, putting practice is essential in order to shorten their scores. For this reason, mats for putter practice devices have been commercially available.

This is a pine with a specified width and length with a cup at the tip, but since this pine is about 50cm wide and 2 to 3m long, it is often left alone. type, and it is impossible to easily bring it indoors and practice putting.

[Purpose of invention]

Therefore, this invention proposes a simple putter practice device that is small, lightweight, and convenient to carry, allowing you to practice putter easily even indoors.

[Summary of the idea]

Therefore, the putter practice device according to this invention,
An indicator thread of a predetermined length that indicates the direction of travel of a golf ball, a thread-wound rotating body rotatably housed in a cylindrical case around which the indicator thread is wound, and a weight body attached to the tip of the indicator thread. and a storage section at the lower end of the cylindrical case, which removably stores the weight body in the lower end of the thread-wound rotating body, and the indicator thread has a plurality of threads arranged at predetermined intervals. It has a marker attached to it. According to this, it can be easily installed on a mat spread indoors, and by simply extending the indicator string to the desired length, it is possible to easily determine the direction and distance of the golf ball, making it ideal for indoor putter practice. Very suitable.

〔Example〕

Next, an example of the putter practice device according to this invention will be explained in detail with reference to FIG. 1 and subsequent figures.

FIG. 1 is a sectional view showing an example of a putter practice device 10 according to the invention, in which a cylindrical case 1 having an open bottom and a predetermined inner diameter has a thread-wound rotating body 2 rotatably housed therein. . The thread winding rotating body 2 is for winding an indicator thread 3 to be described later, and the tip of its rotating shaft 4 is provided so as to protrude above the case 1, and its lower end is screwed into the case 1. The thread-wound rotary body 2 is inserted into the center hole 6 of the support body 5, whereby the bobbin-wound rotating body 2 is rotatably supported by the case 1. To enable the disk-shaped support 5 to be screwed into the case 1, meshing portions 7 are formed at predetermined positions on the circumferential surface of the case 1 and on the outer circumferential surface of the support 5, respectively.

A housing portion 9 is formed on the lower end surface of the support body 5 so that a weight body 8 to which the tip of the indicator thread 3 is tied can be stored in a detachable manner.

In this example, a recess 11 is formed with a predetermined radius on the lower end surface of the support 5, and a disk-shaped attracting body 12, such as a magnet, is attached and fixed to the recess 11, and a storage portion 9 is formed. is configured.

The weight body 8 is made of a metal body, and its size is arbitrary as long as it is smaller than the inner diameter of the case 1, but in order to be able to stretch the indicator thread 3 under tension, the weight body 8 has a certain weight. Requires. In this example, a flat disk-shaped metal body approximately equal to the outer diameter of the adsorbent 12 is used.

In addition, in order to prevent the weight 8 from protruding from the bottom of the case 1 even when the weight 8 is stored in the storage part 9, in this example, the end of the case 1 is placed above the lower end surface of the weight 8. Its length is selected so that it protrudes slightly.

Further, at the end of the case 1, there is a cutout recess 14, which allows the indicator thread 3 to be passed through a portion located in an arbitrary diametrical direction passing through the center of the case 1.
15 is formed.

On the other hand, a rotary knob 17 pivotally connected to the rotating shaft 4 is provided at the top of the case 1, and by rotating the rotary knob 17 in a predetermined direction, the indicator thread 3 is wound around the bobbin rotating body 2. It will be done so that A knurling 18 as shown in the figure is formed on the outer circumferential surface of the rotary knob 17, and a recess 19 into which a finger can be inserted is provided in the upper plane of the rotary knob 17. Made to be rotatable.

Now, as shown in Fig. 2, the indicator thread 3 has a marker Ms for setting the ball at a predetermined position on the weight body 8 side.
At the same time, putter swing check markers Msf and Msb for checking the distance and direction of the back swing and follow swing are placed at a predetermined distance L1 in front and behind the marker Ms, for example, 50 cm, respectively. , also set marker
A predetermined distance L2 from the center point of the set marker Ms is placed on the indicator thread 3 which goes from Ms to the side of the bobbin winding rotating body 2.
For example, distance markers M1, M2, . . . are attached at intervals of 0.5 to 1 m, respectively. The indicator thread 3 therefore has a length of 3 to 5 m.

As the indicator thread 3, it is possible to use fishing line or cotton thread, which is hard to be affected by rolling a ball on the indicator thread, is strong, and is easy to wind up.
Of course, it is also possible to use something a little wider, such as cotton tape. Various markers can be attached to the indicator thread 3 using dyeing, color tape attachment, or other methods. In the case of dyeing, the color can also be changed depending on the type of marker.

In addition, this putter practice device 10 has a diameter of 5 to 10 mm.
cm, and can be configured as a flat body with a height of 3 to 5 cm.

Now, putter practice device 1 configured in this way
To actually practice putter using 0,
First, take out the weight body 8 from the storage part 9, turn the rotary knob 17 to extend the indicator thread 3 by the required length, and place the case on the jacket 19 laid indoors, for example, as shown in FIG. 1 and the weight body 8 are set. In this case, since the case 1 is cylindrical and the weight body 8 is disc-shaped, both can be stably installed as they are on the elevator 19, the floor, or a tatami. The indicator thread 3 is stretched under tension and set so that the indicator thread 3 passes through the cutout recesses 14 and 15. By passing through the notched recesses 14 and 15, the indicator thread 3 is extended parallel to the plane of the jacket 19. After setting, as shown in Fig. 3, place the ball 20 on the set marker Ms, and use the putter (not shown).
Roll the ball 20 to the virtual cup using the .

Since the ball cannot be cupped in unless the ball 20 rolls on the pointing thread 3, the user can practice the direction and distance to the virtual cup while checking the back swing and follow swing.

After completing the exercise, turn the rotary knob 17 to set the instruction thread 3.
When the weight body 8 is wound and the weight body 8 is stored in the storage portion 9 as shown in FIG. 1 after winding, the weight body 8 will not come off due to the attraction force of the magnet.

[Effect of idea]

As explained above, according to this invention, there is a bobbin winder rotor housed in a cylindrical case around which the indicator thread is wound, a weight body attached to the tip of the indicator thread, and a storage unit that removably houses the bobbin winder. This part constitutes a putter practice device. According to this, it is possible to realize a simple putter practice device that is small, lightweight, and convenient to carry, allowing you to easily practice putting, especially indoors.

In addition, in addition to the ball set mark, swing check and distance marks are attached to the instruction thread, so you can accurately check the distance and direction of the ball you hit without relying on visual estimation, making it more effective in practice. It has the practical benefit of realizing a certain putter practice. The device is small and lightweight, so it can be moved freely between practice locations.

Furthermore, when the device is not in use, the weight body 8 can be stored in the case 1 while being attracted to the suction body 12, so that the weight body 8 will not easily come off from the case 1 when the device is being carried around. Therefore, there is no chance of parts being accidentally lost.
