Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a putting practice machine.

[Conventional technology and its problems]

In golf, the quality of your score is largely determined by your putting technique, and therefore it would be advantageous if you could practice using various undulations in conditions close to the actual green.

However, conventional putting practice machines generally have an upwardly sloping base made of board or metal material, and artificial turf is spread over this base.
As a result, the feeling of taking a stance and the rolling of the ball are significantly different from those on the actual green, and the undulation is fixed at a constant level, making it monotonous, leading to players getting tired easily and not being able to master various putting techniques. There was a problem.

In Japanese Utility Model Publication No. 51-43409, an inclined frame is provided next to a stance base 2 in the form of a base plate, and a cloth-lined rubber plate with a plurality of holes is stretched on the surface of the frame, and a cloth-lined rubber A putting training machine has been proposed in which the space under the board is provided with a height difference in width and a spiral wing is provided so as to be rotatable and movable.

However, in this prior art, the ball rolling surface is a cloth-lined rubber plate, so the feeling of taking a stance and the rotation of the ball are significantly different from the actual green, and the putting position is fixed, making it impossible to practice by changing the distance. do not have. In addition, since the rubber plate is simply lifted locally using the helical blades, the slope becomes unnatural, and there are other problems such as being able to attach undulations to only one place on the parting surface. It was hot.

[Means for solving problems]

The present invention was devised to solve the above-mentioned problems, and its purpose is to make the stance state and ball rolling closer to the actual green, and to reduce undulation. It is an object of the present invention to provide a device that can be varied in various ways and allows extremely practical putting practice.

In order to achieve this purpose, the present invention fills the containing part of a frame with an open upper box-shaped containing part and a hollow part surrounding it, and at the same time, the surface of the powder and particulate material layer is An artificial turf with holes at appropriate places is spread out, and a scraping member for forming undulations is arranged between the backing material of the artificial turf and the surface of the powdery material, and the hollow part is provided with a scraping member for forming undulations. a first operating mechanism for moving the scraping member in a direction intersecting its axis to move the surface layer of the powder or granular material to create a height change; and a first operating mechanism for moving the surface layer of the powder or granular material by changing the angle of the scraping member. This configuration includes a second actuation mechanism for changing the amount.

[Effect of the embodiment]

Since the present invention has the above-mentioned configuration, when practicing putting, the player takes a stance on the artificial grass 3 across the frame 1, and hits the golf ball with the putter toward the hole cup 3c. Since the artificial turf 3 is spread over the powder layer A, it does not have a rigid or hard feel like metal plates, etc., and the appropriate fluidity and cushioning properties of the powder make it look like a real green. You can feel as if you were under your feet and the rolling and condition of the ball. Also, because the artificial turf 3 is supported by a layer of powder, your stance position is not fixed, so you can take a stance from any position and make long putts. You can practice putting distances of various distances such as short putts.

In the above practice, when the first actuating mechanism 5 is activated, the sprocket 5 is activated via the transmission shaft 5d.
e, 5e rotates, which causes chains 5g, 5
The guide members 7 and 7' move through the guide members 7 and 7', and the undulation forming member 4 supported by these guide members 7 and 7' moves along the surface of the powder layer A as shown in FIG. Since the particles A are moved by the scraper action caused by the movement, the height of the surface layer changes. For example, by moving the undulation forming member 4 in the direction shown by the arrow in FIG. 2, a smooth slope with an upward tendency toward the hole cup 3c is formed. If the second actuating mechanism 6 is activated during such movement of the undulation forming member 4, the shaft portions 4a, 4a' rotate, thereby causing the undulation forming member 4 to rotate.
Since the angle changes, the degree of the inclination can be increased or decreased as desired, and when the undulation forming member 4 is in a horizontal state, the lower surface is aligned with the surface of the powder layer A. Alternatively, if the undulation forming member 4 is made to float slightly above the surface, a two-tiered green can be easily formed by leveling the undulation forming member 4 by a required distance during movement, and tilting and moving it again. In addition, since the movement of the powder/granular material layer is absorbed by the deformation of the rubber plates 2b, 2b, it does not flow out from the storage section 2.

Furthermore, as in the embodiment shown in FIG.
If the first actuating mechanism 6, 6' is provided and the driving force of the first actuating mechanism 5 is turned on by the clutch mechanism 13, 13', a more complicated undulation system having a hook line and a slice line is provided. can form a sixth
When the undulation forming member 4 is allowed to move in an arc as shown in the figure, the undulation can be extremely complicated.

Furthermore, there are jacks 18a, 18 on the four corners of the frame.
b, 18c, and 18d, by selectively operating them, the entire frame 1 is tilted back and forth and left and right, making it possible to simulate a state closer to a natural green.

[Effect of idea]

According to the present invention described above, the storage part 2 of the frame 1, which has a box-shaped storage part 2 open at the top and a hollow part surrounding it, is filled with powder and granules, and a layer of powder and granules is filled. An artificial turf 3 with holes formed at appropriate places on the surface is spread, and a scraping member 4 for forming undulations is arranged between the backing material 3b of the artificial turf 3 and the surface of the powdery material, In the hollow part, there is provided a first actuating mechanism 5 for moving the scraping member 4 in a direction crossing its axis to move the surface layer of the powder and granular material to create a height change, and a first actuating mechanism 5 for moving the scraping member 4 in a direction intersecting the axis of the scraping member 4, and for adjusting the angle of the scraping member 4. Since the second actuation mechanism 6 is provided to change the amount of movement of the powder and granular material on the surface layer, the following excellent effects can be obtained.

The structure of the putting surface is artificial turf 3 supported by a layer of powder and granules.Moreover, the surface layer of the granules A is moved to create heights, rather than directly undulating the artificial turf 3, so that the sloping state is natural. It is possible to reproduce the rolling state of the ball almost equivalent to the green on an actual golf course,
In addition, since the artificial turf 3 is stably supported by the powder layer, the putting stance position can be freely taken anywhere, and long putts and short putts can be practiced as if they were real.

Since the scraping member 4 for forming undulations is movable in the direction intersecting the axis thereof, and the angle of the scraping member 4 can be freely changed,
The undulations can be formed at multiple locations on the parting surface, and the degree of inclination at the multiple locations can be set as desired, such as strong or weak. As mentioned above, you can choose your stance position as you like. Therefore, it is possible to easily perform practical putting practice that is rich in countless variations.

Artificial grass stretched in a hollow shape when forming a slope 3
The artificial turf is not deformed by applying local pressure directly to it, but is deformed by the moving pressure of powder and granules, so it does not require excessive force, and damage and fatigue to the artificial turf can be reduced.
