In the present invention, a base plate is a base plate on which artificial turf is laid. A ball collecting groove 4 is provided on a peripheral edge portion 3 of the base substrate, which is a portion where the green of the artificial grass is cut off, and an outer wall 5 is provided further outside the ball collecting groove 4 so as to prevent the ball from jumping out. The height of the outer wall 5 from the artificial grass surface and the groove width of the ball collection groove 4 are preferably 50 mm to 200 mm and 40 mm, respectively.
It is selected from the range of mm to 100 mm. It is preferable that the ball collecting groove 4 and the outer wall 5 are provided in a desired portion around the assembled green so as to surround the green, and are necessarily provided in one side portion or both side portions of all the base boards. It is not something that can be done.

Balls that have been hit off the green by the above structure are blocked by the outer wall 5 and fall into the ball collecting groove 4 to be collected. Here, it is preferable that the ball collection groove 4 is formed with an inclination such that the ball rolls naturally. That is, the golf driving range 1 of FIG. 1 will be described. The bottom surface of the groove g is continuously and continuously inclined from the ball collecting groove 4 of the base plate g to the ball collecting grooves 4 of the base plates f, e, d, c, b, and a. If it is formed so as to
The golf balls that have fallen into the ball can be successively rolled in the ball collecting groove 4 and collected in the ball pool 6 of the tee ground a, picked up and played again.

As the artificial grass laid on the base substrate, a grass element made of vinylidene chloride is preferable from the viewpoint of weather resistance, but the present invention is not limited to this and it is not limited to nylon or polypropylene. Artificial grass of known material can be used. From the viewpoint of cleaning dust and mud adhering to the turf surface with water, a water-permeable artificial turf is used, and the surface of the base plate on which the artificial turf is laid has cleaning water collecting grooves 4 It is preferable that the water collecting port 4 is formed with a slight inclination so as to collect water, and that the ball collecting groove 4 is further provided with a drainage port.

FIG. 2 shows a state in which the base plates a, b, c, d, e, f, and g are developed. The artificial turf green may be simply placed on the turf laying surface (usually in the center) on the upper surface of the base substrate, but it is preferably fixed with adhesive or metal fittings so that the turf is not displaced or wrinkled. To be done. Further, an easily attachable / detachable fixing means such as a magic tape is arranged on the turf laying surface and the base cloth surface of the artificial turf,
Laying artificial turf is convenient because you can easily replace it with an artificial turf with a different grain.

The base substrate needs to be formed to be strong and lightweight. For example, fiber-reinforced resin (FRP) such as glass fiber-filled polyester resin, carbon fiber-filled polyester resin or polypropylene resin with steel wire, or aluminum is used. It is formed of a material that satisfies the conditions. Among these materials, aluminum is convenient because it can be recycled.

An example of the dimensions of the base substrate is a width of about 4 m and a length of about 2 m, and in some cases, the base substrate is subdivided into about half. Therefore, the base substrate and base plate of the present invention can be easily carried, installed, removed, and stacked. In general, most of the base boards constituting the golf driving range of the present invention are manufactured with the same outer dimensions and the same vertical movement device mounting dimensions except for undulation on the green. This facilitates replacement and replacement of the base board and base plate, and enables a variety of course designs.

FIG. 3 shows the base plates a, b, c, d, e, of FIG.
It is CC sectional drawing about f and g. Here, each base substrate has various undulations as needed, for example, the ground a is a substantially flat plane, and the rough or fairway b is increased in height sequentially,
c is a progressively lower height, d is a higher central portion, e is a substantially flat triangular or fan-shaped flat surface, f is a base substrate formed so that the height is sequentially increased, and g is a substantially flat mound. There is.

[0016] In such a combination, it is possible to appropriately replace the base substrates within a range in which the undulation levels of the base substrates are substantially the same at the joints of the base substrates, and various different undulations can be used. Obtainable.
Further, the number of base plates used as a rough or fairway can be freely increased or decreased depending on the size and length of the installation place to be a short hole or a long hole.

The putting green g may have a substantially gourd shape or any other shape other than the substantially circular shape shown in the drawing. Further, the green has at least one hole 2, but it is preferable that a plurality of holes, for example, 2 to 6 holes are provided in advance and one of the holes is removed and the lid is covered. Reference numeral 2'in FIGS. 1 and 2 denotes a hole in the state in which the lid is covered, and FIG. 6 shows a cross section of the hole 2 '. In FIG. 6, the lid is composed of a circular pedestal 7, an artificial turf 8 stretched on the surface of the pedestal 7, and a rod 9 having a male screw vertically attached to the center of the back surface of the pedestal 7. on the other hand,
A female screw 10 is fixed to the lower part of the hole 2'on the putting green g side, and the hole can be covered by inserting the rod 9 having the male screw into the female screw 10 and rotating the artificial grass 8. it can.

The lid of the hole of the present invention is not limited to the above-mentioned structure, but the method of this embodiment in which the artificial turf 8 is moved up and down by the screwing operation allows the height of the lid to be finely adjusted. Adjust the height of the surface to be the same as the surrounding green,
It is preferable because the grass can be aligned. In the golf driving range of the present invention in which a large number of holes 2 ′ having such a lid are provided, the position of the hole 2 can be freely changed according to preference.
It is a lot of fun as well as widening the range of golf practice.

Furthermore, it is also preferable to provide an artificial pond 11 and a bunker 12 on the artificial grass green to make the course more varied. The bunker 12 of FIG. 1 is constructed by laying artificial grass containing sand so as to be slightly lower than the surrounding green.

A plurality of vertical moving devices independent of each other are fixedly provided on the base substrate of the present invention. The number is preferably 3 to 10 per base substrate. Further, the position at which the vertical movement device is fixed and installed is preferably the peripheral edge portion 3, for example, the most end portion shown in FIG. However, as will be described later with reference to FIGS. 9 and 10, the vertical movement device may be provided below the green.

FIG. 5 shows a jack device 13 as an example of the vertical moving device. The jack device is a simple device including a jack bolt 14, nuts 15 and 15 ', and a base 16. Insert the jack bolt 14 into the mounting hole 17 of the base board, and sandwich the mounting hole 17 between the nuts 15 and 15
The jack device 13 is fixed to the pedestal substrate by tightening with ‘′. Further, by changing the tightening positions of the nuts 15 and 15 ', the height of the base board from the ground or floor can be easily adjusted.

The stand 16 of the jack device is used by placing it on an installation surface such as a floor, concrete or foundation. It is preferably fixed to the installation surface by the anchor bolts 18. According to this structure, the base board is firmly fixed to the installation surface via the vertical movement device, so that the base board does not move or bounce during play. You can play safely without worry. On the other hand, when the vertical moving device is used without being fixed to the installation surface, it is preferable to increase the number of vertical moving devices and fix the side surfaces of the base substrate that are in contact with each other with bolts or the like. Since the vertical movement device of the present invention is provided independently of each other, it is in contact with the installation surface at a point or a portion close to the point, and even if it is slightly uneven, it is possible to secure a safe play simply by placing it. ..

7 and 8 show another preferable example of the base substrate, in which the play zones 19 and 20 are attached to the peripheral edge portion 3. The play zones 19 and 20 are used, for example, when playing a ball near the collecting groove 4. 7 shows the play zone 19 with the tip of the toe lowered, and FIG. 8 shows the play zone 20 with the tip of the toe raised, but of course, it may be a flat surface.
In addition, in the case of FIG.
If it is blocked by 9, it is not always necessary to provide the outer wall 5. It is preferable to attach artificial grass or a rubber sheet to the play zones 19 and 20 so as to absorb the bounce of the ball and prevent the ball from slipping.

FIG. 9 is a partial plan view of another golf driving range of the present invention, and FIG. 10 is an enlarged sectional view of a portion D-D in FIG. The driving range shown in FIG. 9 is one in which two base plates are juxtaposed in the green width direction to realize a wide green. Then, FIG. 10 is an example of the vertical movement device 22 provided immediately below the green. In the vertical movement device 22, a nut 23 having gears arranged around it is used instead of the nut 15 'of the vertical movement device shown in FIG. 5, and only in this point, the two differ. The rotation of the nut 23 is performed through the bottom space of the base plate by a long chain (not shown) meshed with its gear. Reference numeral 24 in the drawing is a cover having an artificial grass arranged on the upper surface. Of course, the vertical moving device 22 provided directly under the green can also be applied to the base substrate as shown in FIG. 1, and is used for adjusting and reinforcing the base substrate.

As described above, the vertical moving device of the present invention has been described with the jack devices 13 and 22. However, the vertical movement device of the present invention is not limited to these screw jacks, and for example, a rack jack that moves the rack up and down by the action of a pawl, or a hydraulic pressure generated by the reciprocating motion of a small plunger is supplied to the cylinder. Then, a device such as a hydraulic jack for moving the ram up and down, a jack device such as a hydraulic jack driven by a hydraulic pump, a spring with a stopper, etc., that can be vertically moved and fixed to the base board, may be used.

Further, the two vertical moving devices corresponding to each other with the boundary line between the adjacent base plates sandwiched therebetween may not be separate, but may be one common vertical moving device. In this case, the base plates are fixed to each other with a fixed plate sandwiching the boundary line, and the fixed plate is driven by a common vertical moving device. According to the above configuration, even if the vertical movement device is driven, a step does not occur between the adjacent base plates, and adjustment of the step is not necessary, so that the undulation can be changed quickly and easily.

By operating the up-and-down moving device, the desired pedestal substrate can be vertically moved by, for example, 0.5 mm to 3 cm to slightly change the undulation not only in the length direction of the golf practice table but also in the width direction. it can. If necessary, the base plates may be fixed to each other using bolts or magnets, the heights of the adjacent base plates may be made uniform, and the mutual level positions may be fixed.

[0028]

[Effect] Since the present invention has the above-described structure and operation, the golf driving range of the present invention can be set up very easily,
Further, the course of the golf driving range can be easily changed to a state having various desired undulations. In particular, by using a combination of various base plates having a rectangular shape, a triangular shape, a polygonal shape, a fan shape, an atypical shape, etc. in a plan view, it is a course having a bend or undulation, and further a short hole or a long hole. Since the golf course can be variously varied according to demands, the practitioner can improve quickly.

In the golf driving range of the present invention, since the base boards are fixed to a plurality of independent vertical moving devices, it is possible to practice the golf stably even if the practitioner exercises on them. .. Since the golf driving range of the present invention is composed of an independent base plate, the base plate can be easily installed, removed, stacked, etc., and can be stored and installed in a small space, for example, in a building. It is easy to install on the rooftop, on the edge of the amusement park, on the poolside, etc.
