The main plate 9 of the step plate 7 is made slant against the auxiliary plate 8 by a second cylinder 34. Various slant faces can be made by synthesizing the inclined angles of the two sides of step plate 7 mutually crossing in right angles. The main plate 9 is covered with a thick rubber plate. This rubber plate is elastically deformed in the thickness direction to form swelled parts or recessed parts on the surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf practice apparatus and a ball set mat which are mainly installed in a golf practice range to practice hitting golf on a sloping ground.

[0002]

2. Description of the Related Art In competitions on the fairways of golf courses, there are many opportunities to hit a ball on a sloping ground except for the first shot and the putter on the green. On the contrary, the ball is rarely hit on a completely flat ground, and the ball is often hit from a slightly inclined point. However, in a conventional golf driving range, the ball is placed on a flat grass mat or the ball is placed on a tee standing on the grass mat to hit the ball. Golf beginners need to practice on such flat terrain, but those skilled in the art need to practice hitting balls on sloping terrain as in competition on fairways. The reality is that such practice can hardly be done.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a golf practice apparatus capable of hitting a ball in a golf course in almost the same state as hitting a ball on the fairway of the golf course. ..

[0004]

A first means adopted by the present invention to solve this problem is a main use surface part centering on a base, a tread support member fixed to the base, and a hinge part. And the auxiliary use surface part are foldably connected,
A tread plate in which the auxiliary use surface part is rotatably supported by the tread plate support member around a support shaft that is substantially orthogonal to the hinge part, and for tilting the entire tread plate by rotating about the support shaft. And a second driving means for tilting the main use surface portion of the tread plate with respect to the auxiliary use surface portion by rotating the hinge portion around the hinge portion as a center, thereby constructing a golf practice apparatus for sloped land. By tilting the main use surface portion of the tread plate on which the player mounts to practice hitting independently of each other about the support shaft and the hinge portion by the first and second driving means, That is, various inclinations are generated by synthesizing inclinations in two different directions that are substantially orthogonal to each other on the main use surface portion of the tread. In the same second means, the tread plate is entirely made of a thick elastic plate, and the tread plate is locally elastically deformed along the thickness direction by the third driving means, and an appropriate number is formed on the upper surface thereof. That is, it is possible to form a ridge or a depression.

[0005]

The main use surface portion of the tread rotates and tilts about the support shaft by the first driving means, and at the same time, tilts about the hinge portion by the second driving means. The support shaft that supports the tread to the tread support member and the hinge that connects the main and auxiliary use surface parts of the tread are almost orthogonal, so the main use surface part of the tread is almost orthogonal. Inclination in two different directions independent of each other. By freely combining the independent inclinations of the treads in two different directions, various inclined surfaces can be created on the upper surface of the treads, and the player who practices golf hitting on the treads is almost the same as the fairway on the golf course. You can practice in this state. Further, if the entire tread is made of an elastic plate, and the tread is locally raised or recessed along the thickness direction by the third driving means, the tread of the tread may be changed due to the inclination of the entire tread. Since the ridges or the depressions are added to the upper surface, it is possible to generate an inclined surface that is closer to the actual inclined surface that is generated on the fairway, and further enhance the golf practice effect on the inclined surface.

In this way, by independently operating the first and second cylinders 25 and 34, the inclinations in two different directions orthogonal to each other can be arbitrarily combined, and the main use surface portion 9 of the tread 7 can be combined. Various inclined surfaces can be freely generated.

FIG. 11 shows a pit 10 formed by using the above-mentioned golf training apparatus A at a place where a ball is hit on a golf driving range.
It is installed inside and the tread 7 is shown on the upper surface of the ground G. Since the player P puts on the main use surface portion 9 of the tread 7 and hits the ball B to practice, the player P
Is right-handed, the practice direction of the hinge 22 connecting the auxiliary use surface portion 8 and the main use surface portion 9 of the tread 7 is made to coincide with the direction of the flight line of the ball B, and golf practice is performed. The device A is installed in the pit. The tread 7 is inclined, and the ball setting mat M shown in FIGS. 12 and 13 is used in order to set the ball B on the upper surface so that the ball B does not roll. In this mat M, innumerable artificial grass 56 is planted on a substrate 55 made of a thin rubber plate, and a split spherical concave portion 57 into which a part of the ball B can be fitted is formed on the upper surface of the innumerable artificial grass 56. Many are formed.

When the player P is practicing hitting golf, as shown in FIG. 11, the mat M is laid on the upper surface of the main use surface portion 9 of the tread 7, and the golf ball is placed in the recess 57 of the mat M. The ball P is put in, and the player P rests on the main use surface portion 9 of the tread 7. 8 to 1
As shown in FIG. 0, the player P uses an inclined surface corresponding to almost all inclined surfaces from the slight inclined surface to the large inclined surface in the fairway of the golf course to the main use surface portion 9 of the tread 7.
Since it can be generated by, it is possible to practice how to determine the position of the foot and how to swing the club C on the same slope as the slope on the fairway. Furthermore, FIG.
As shown in FIG. 10, when the main use surface portion 9 of the tread 7 is inclined or is horizontal, one or both of the third cylinders 42 is operated so that When the two raised portions 50 are formed, the raised portions 50 form a shape similar to the raised portion of the ground on the fairway, so that the player P can perform batting practice when the ball B falls in the depression of the fairway. .. When the golf practice device A described above is installed in the pit 10 and the tread plate 7 is inclined, a large gap is formed between the peripheral part of the tread plate 7 and the pit 10, and a ball is formed from this part. Since B or the like may fall into the pit 10, covering the void with a net 58 can prevent the above-mentioned problems.

In the above embodiment, the thick rubber plate 19 forming the tread plate 7 is elastically deformed in the thickness direction to form the raised portion 50 or the recessed portion 60 on the upper surface of the third cylinder. I am using two 42, but this third
The number of cylinders 42 to be used and the position of installation are arbitrary, and an appropriate number of raised portions 5 can be provided at almost any position on the thick rubber plate 19.
It is possible to increase the practice effect of golf on a sloping ground by forming 0 or the concave portion 60. Further, when the main use surface portion 9 of the tread 7 is not inclined with respect to the auxiliary use surface portion 8, the auxiliary use surface portion 8 can be used as a practice tread, and the use area is widened.

[0015]

In the golf practice device according to the present invention, the tread plate for the player to mount and practice hitting golf is the first step.
And the second driving means independently inclines in two different directions that are substantially orthogonal to each other. Therefore, by combining the inclinations of the treads in the two different directions, various inclined surfaces can be generated on the upper surface of the tread. Players who practice hitting golf can be practiced in a state almost the same as a fairway on a golf course. Further, if the entire tread is made of an elastic plate, and the tread is locally raised or recessed along the thickness direction by the third driving means, the tread of the tread may be changed due to the inclination of the entire tread. Since the ridges or the depressions are added to the upper surface, it is possible to generate an inclined surface that is closer to the actual inclined surface that is generated on the fairway, and further enhance the golf practice effect on the inclined surface. Further, when the ball set mat according to the present invention is used, even if the tread laying the mat is tilted, a part of the ball is inserted in the recessed spherical concave portion, so that the ball can be moved along the inclined surface. You can practice hitting golf on an inclined surface without any problems.
