Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a golf practice apparatus that can be installed at a practice field or at home.
[0002]
[Prior art]
For example, an artificial turf is generally laid on the practice surface of a golf practice practice field, and practice is practiced through that practice.
[0003]
[Problems to be solved by the invention]
However, since this practice surface is flat, the practice is monotonous. On the other hand, when actually playing a game in the green, not only the flat surface but also rough, bunker, etc. As there are various irregularities and inclined surfaces, good results cannot be expected by practice only on flat surfaces.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a golf practice device that enables effective practice in conformity with an actual battle.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 is a golf practice apparatus installed in a golf driving practice field or at home, etc., and a frame having a certain height on a practice surface with a fixed periphery. The frame is provided with a horizontal axis that is driven to rotate horizontally by a motor, and a spherical drive roller provided on the horizontal axis, and a large number of used golf balls are placed in the frame. The artificial turf can be freely deformed up and down by rotating the horizontal axis with the drive roller in a state of being turned.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments .
[0006]
FIG. 1 shows a preferred embodiment of the present invention. Reference numeral 1 denotes a frame having a recess formed in a practice field, and the frame 1 is formed of a metal plate, resin, wood, or the like .
[0007]
At home, it may be formed by digging a garden, or if it is concrete, the frame 1 may be installed on the concrete as a frame .
[0008]
The frame 1 is rectangular when viewed from above, but may be round or polygonal .
[0009]
2 is a practice surface and corresponds to the upper surface of the artificial turf 3 .
[0010]
The artificial turf 3 is affixed on a base 4 having a shape substantially corresponding to the frame 1, and the base 4 can be tilted back and forth via a central fulcrum shaft 5 .
[0011]
Reference numeral 6 denotes a bracket attached to the bottom of the base 4, and 7 denotes a bearing body provided upright from the frame 1 side. The bearing body 7 is provided upright from an attachment block 8 made of concrete or the like .
[0012]
The bearing body 7 may be fixed to the frame body 1 .
[0013]
Reference numeral 10 denotes a support cylinder erected from the mounting block 8. A hydraulic cylinder 11 such as hydraulic pressure, water pressure or pneumatic pressure is inserted into the support cylinder 10 in a vertical direction, and a roller at the tip of the rod 12 of the cylinder 11 is fixed. Is engaged with the long hole 13 of the base 4.
[0014]
The solid line in FIG. 1 indicates that the artificial turf 3 is in a horizontal state. By operating the control box 15 embedded in the floor 14, the practice surface 2 can be tilted to a desired front and rear angle as indicated by the virtual line. It has become. Therefore, by practicing the practice surface 2, it is possible to practice as if it were a real battle.
[0015]
The embodiment shown in FIG. 2 is a base 4 provided with an artificial turf 3 having an uneven practice surface 2, and this embodiment is also tiltable via a support shaft 5. Thus, the cylinder 11 may be installed in the horizontal axis direction. In addition, although it is the same also in the following embodiment, the artificial turf 3 can be made into a main turf and can be exchanged.
[0016]
The embodiment shown in FIG. 3 is one in which sand 17 is placed in the base 4 and can be tilted, and is suitable for practice such as bunker shots.
[0017]
The embodiment shown in FIG. 4 is a specific example of the artificial turf 3, and grooves 19 a... Are freely formed in the bottom board portion 19 of the artificial turf 3. The groove 19a has a round groove shape to enhance durability.
[0018]
In the embodiment shown in FIG. 5, a plurality of hydraulic cylinders 21 such as hydraulic pressure, hydraulic pressure, pneumatic pressure, etc. are arranged on a plane, and a circular umbrella-shaped receiving plate 23 is provided on the upper end of the rod 22 of the cylinders 21. Can be moved up and down individually. The virtual line indicates the artificial grass 3.
[0019]
The embodiment shown in FIG. 6 shows another driving method, in which one or a plurality of orthogonally extending roller shafts 26 project from an inclined driving shaft 25 and the roller shaft 26 has a spherical roller 27. Are arranged in a freely rotatable manner. By rotating the drive shaft 25, the rollers 27...
[0020]
In the embodiment shown in FIGS. 7 and 8, the driving means is an air bag 29 that inflates and contracts in a pneumatic manner, and these are appropriately inflated and contracted so that the artificial turf 3 thereon is uneven. It is a thing. The air bag 29 can be practiced stably if it is made as difficult to deform as possible. Further, water can be used instead of air.
[0021]
In the embodiment shown in FIG. 9, the shower device 32 is installed so as to shower from the upper side toward the artificial grass 3 of the practice device. This is due to the fact that there was rainfall in the actual battle. In this case, you can practice wearing rain gear as in the actual battle. Moreover, you may install the electric fan 33 which generate | occur | produces a wind so that it may show simultaneously.
[0022]
In the embodiment shown in FIG. 10, a large number of used golf balls 35 are placed in a frame 1 having a constant height, and a horizontal rotation driven horizontally by a motor 36 is put in the frame 1. The shaft 37 and the drive roller 38 having different spherical diameters disposed on the horizontal shaft 37 are configured, and the drive roller 38 is slowly rotated while the horizontal 37 is driven to rotate horizontally. The artificial turf 3 having the upper surface as a practice surface is freely deformed up and down, and golf practice is performed using the deformed practice surface .
[0023]
In addition, as shown in FIG. 10, you may make it the periphery of the artificial grass 3 pull with means, such as a check rubber 40. FIG. This can be applied to all the embodiments described above. Moreover, you may fix the periphery of the artificial turf 3 with an anchor. Further, in the embodiment shown in FIGS. 1 to 10, after being tilted, it is once locked in that state, but it is possible to continue tilting.
Further, in the above-described embodiment, it is mainly configured for the practice of shots. However, a practice device that assumes a putt in the green may be similarly configured.
Furthermore, the artificial turf can be changed to a rough state suitable for rough shots.
[0024]
【The invention's effect】
Since the present invention is configured as described above, it is possible to practice effectively on a flat surface as well as on an inclined surface or a green surface with a compound inclination, more effectively in practice.
