Description

[Detailed description of the invention] <Industrial application field> This invention relates to a golf practice device particularly suitable for putting practice, and the direction of undulation can be freely changed by rotating the disc. In addition, the disk can be easily rotated manually, and the disk, which is easy to rotate, can be easily fixed.

<Prior art and its problems> The best way to improve your golf skills is to practice on a golf course, but due to geographical, time, or economical issues, it is difficult to play golf partially. Exercise equipment that allows this has already been developed.

For example, the putter practice device shown in FIG. 6 is one such device, in which artificial turf b is stretched over a table a having fixed undulations, and a cup c is formed in a portion thereof. According to this, although the structure was extremely simple and suitable for mass production, there was a problem that the undulating state could not be changed, the pattern could not be specified, and the effect of practice could not be expected.
Therefore, as methods for changing the undulation, for example, there are methods shown in Japanese Utility Model Publication No. 50-13176, Japanese Patent Application Laid-Open No. 52-540, Japanese Patent Application Laid-Open No. 63-51876, and Japanese Utility Model Application Publication No. 63-96866. However, these are artificial turf that partially rises in a conical shape (pointed hat shape), and are
In the case of the one shown in Publication No. 96866, artificial turf is placed on a pine-shaped disk with a cup formed in the center, with the grass facing in one direction, and the disk is rotated. Therefore, in order to change the direction of the grass grain and to give undulations to the pine-shaped disc, a reduction motor different from the motor for rotating the disc is used, and this reduction motor is The protrusions that should give undulations during operation are
Since the disk rotates in a planetary manner with respect to the rotation axis of the disk, not only is the structure complicated, but the material forming the disk is pine, so the undulations formed are cone-shaped. Moreover, when walking on the disk, stability is lacking. Furthermore, in the case described in the above-mentioned Japanese Utility Model Publication No. 63-96866, the member for forming the undulations rotates around the hole while pushing up the circular pine constituting the green from below. Although the undulating state is changed, the pine is independent of the pine constituting the fairway and rotates near the end of the member for forming the undulating shape. As shown, the presence of the member causes the ends of the green mat to rise. Therefore, if the ball rotates toward the teeing ground rather than the hole, the ball may fall under the floating pin. It is necessary to use the golf ball within a range of up to 180 degrees, but this makes it meaningless to form undulations and is fruitless as a golf practice. Furthermore, as shown in FIG. 7, in a golf practice device in which artificial turf is arranged on the upper surface of a movable floor that partially moves up and down, the movable floor is formed of expanded metal d to provide a sense of realism on the actual green. These golf practice devices are designed to exhibit the following effects, but they are all superior to the device shown in Figure 6 in that they can realize a wide variety of combinations of undulations. However, not only is the device large and the mechanism complicated, but it is also not easily available at a low price.

In addition, examples of devices that allow the position of the cup to be changed freely include the Utility Model 59-
There is a device disclosed in Japanese Patent No. 145960, which has a structure in which a relatively large hole is formed in a part of the golf practice device and a disc with a cup is rotatably engaged with this hole. In order to change the position of the cup, the disc must be manually rotated, and the larger the training device disclosed in the publication, the more difficult it is to manually rotate the disc. This poses a problem in that it is difficult to hold and rotate it, making it impractical.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the golf practice device according to this invention has a cross section on the lower surface of a disk with artificial grass on which arbitrary undulations are fixedly formed on the upper surface. An annular rotation ring having an inverted L shape is interposed therebetween, and an annular fixed ring having an L-shaped cross section facing the rotation ring is fixed to the base, and a wheel in contact with the rotation ring is disposed on the fixed ring. ,
In addition, a braking device that can be freely engaged and detached from the rotating ring is provided, and a plurality of cups are formed on the disc, and a removable lid with artificial turf is provided on the cup, so that the rotation of the disc is controlled. The direction of the undulation can be freely changed by rotating the disk, the disk can be easily rotated manually, and the disk that is easy to rotate can be easily fixed. It has been made possible to do so.

<Example> Next, an example of the golf practice device according to this invention will be described based on the drawings. 1 is a fixed floor surface, and 2 is a circular hole formed in a part of this fixed floor surface 1. be. Reference numeral 3 denotes a disk rotatably disposed in the circular hole 2, and an arbitrary undulation is formed on the upper surface of the disk 3. The above-mentioned undulations for the disk 3 can be formed by using any undulating material 4 such as rubber, plaster, mortar, or synthetic resin, but this undulation can be has a fixed and specific shape. Further, the following means can be used to configure the disk 3 to be rotatable. That is, as shown in FIGS. 3 and 4,
An annular guide plate 5 is fixed to the side edge of the lower surface of the disk 3, and the rotating ring 6 is connected to the support base 7 through an annular rotating ring 6 having an inverted L-shaped cross section that is in contact with the inner surface of the guide plate 5 and the lower surface of the disk 3. An annular fixed ring 8 having a symmetrical shape to the ring 6 is fixed, and a vertical wheel 9 and a horizontal wheel 10 interposed between the rotating ring 6 and the fixed ring 8 are arranged on the fixed ring 8. Reference numeral 11 indicates a plurality of cups formed on the disk 3, and this cup 11 is formed at an arbitrary position on the disk 3.
A removable lid 12 is provided. Reference numeral 13 denotes artificial turf arranged on the upper surfaces of the fixed floor surface 1, the disc 3, and the lid 12, but this artificial turf 13 is arranged independently on the fixed floor surface 1, the disc 3, and the lid 12, respectively. There is. 14 is a braking device for the disk 3, and 15 is a control rod that reciprocates in the lateral direction by an operating lever 16. A brake shoe 17 is provided at the tip of this control rod 15, and
It is configured to be able to approach and separate from the rotating ring 6. still,
In the figure, 18 is a ball stopper.

<Operation> The brake shoe 17 of the control rod 15 is then separated from the rotating ring 6 by the operation lever 16. Then, the brake on the disc 3 is released, and the disc 3 can be rotated by hand, for example. In this case, the rotating ring 6 is not fixed to the lower surface of the disc 3, but rotates together with the disc 3 due to its close contact with the disc 3, and also rotates smoothly due to the presence of the vertical wheels 9 and the horizontal wheels 10. I will do it. When the disk 3 has rotated to a desired angle, the control rod 15 is again operated by the operation lever 16.
The disc 3 can be braked by causing the brake shoe 17 to pop out and press the rotating ring 6 against the brake shoe 17. A desired cup 11 is selected and used, and the cup 11 can be opened by removing the lid 12.

<Effects of the invention> As described above, according to the golf practice device according to the invention, an annular rotation ring having an inverted L-shaped cross section is provided on the lower surface of the disk with artificial turf, which has an arbitrary undulation fixedly formed on the upper surface. At the same time, an annular fixed ring having an L-shaped cross section facing the rotating ring is fixed to the base, and a wheel that contacts the rotating ring is disposed on the fixed ring, and a wheel that is connected to and detached from the rotating ring is disposed on the base. In addition to installing a flexible braking device,
A plurality of cups are formed on the disk, and a removable lid with artificial turf is provided on the cup, so that the direction of undulation can be controlled by rotating the disk. In addition to being able to freely change the disc, the disc can be easily rotated manually, and a disc that is easy to rotate can be easily fixed. It also has the effect of being able to change the combination of reverse stitches.
