Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a running path for golf course carts.

BACKGROUND OF THE INVENTION In recent years, golf courses have been using golf bag transport carts that are guided by loop lines.
However, this cart uses a pick-up coil installed at the front end of the cart to detect the magnetic field belt generated in the buried guide wire on the asphalt-paved management road or cart-only road built around the course. It is an unmanned system operated by remote control, and the player on the fairway and the cart on the managed road or cart-only road are quite far apart even at the shortest distance, so it takes time to change clubs and play is delayed.
It also required a lot of effort on the part of the players.

Therefore, it is conceivable to switch from unmanned operation to manned operation and drive the cart around the course like a general electric cart, but in this case, not only would the advantage of unmanned guidance be eliminated, but also the weight of the bag would be added, making the cart heavier. Repeated free running within the fairway can cause problems such as damage to the grass on the fairway. However, like the managed roads and cart-only roads, it is not possible to provide a wide cart running path with guide lines embedded within the fairway because it would interfere with play.

In addition, two rails made of synthetic resin pipes are laid protruding directly on the ground surface covered with grass, and have grooved wheels that fit into the rails to prevent them from coming off the rails. A transport device for golf bags has been proposed in which the wheels are guided by the rails and the rails are laid protruding above the ground surface, so the golf bags cannot be transported easily. Not only is it difficult to detach and return the transport vehicle from the rails as necessary, but even during normal driving, the rails move horizontally and vertically on the ground surface due to loads such as lateral G and vertical G. By moving
Excavation of soil on the ground surface or crushing of grass near the rails impairs the growth of lawns and the aesthetic appearance of the ground surface, and especially when the ground surface becomes soft due to rainfall or watering, the rails may become buried. There is a risk that the wheels of the transport vehicle may come into direct contact with the ground surface without being supported by the rails, causing them to float up and derail.Furthermore, synthetic resin pipes for the rails, such as common PVC pipes, have poor weather resistance and rigidity. Also, the friction coefficient was insufficient, and from the above points, it was not sufficient for practical use.

Problems to be Solved by the Invention The present invention was devised in view of the above-mentioned circumstances, and it detects the magnetic field generated in the guide wire and allows unmanned golf course carts to move along the running path with almost no hindrance to play. To provide a running path for a cart for a golf course that can be safely, reliably, and easily constructed in a course without causing any problems.

Means for Solving the Problems The present invention lays a guide line along the golf course, and also aligns a plurality of rails with the width of each wheel of the golf course cart to the running line of each wheel of the golf course cart. Each rail is buried at a constant distance from the guide line so that the upper surface of the rail is flat and approximately at the level of the ground surface,
The feature is that grass is grown between the rails and on the ground surface outside the rails.

Function The present invention has a plurality of rails corresponding to each wheel of a golf course cart laid so as to maintain a constant distance relationship from the guiding line so as to match the running line of each wheel. The magnetic field generated in the guide wire can be uniformly detected by the detection unit on the golf course cart that runs unmanned above, thereby accurately controlling the steering of the golf course cart. Therefore, the cart can sufficiently withstand loads such as lateral G and vertical G during unmanned running, and is restrained on the rail, allowing the cart to run stably without coming off the rail. Therefore, each rail can be narrowed to the corresponding wheel width, and is buried so that the top surface of the rail is flat and approximately at ground level, and grass is placed on the ground between and outside the rails. Because the grass is covered with vegetation, the upper surface of the rails located below the grass growth surface is hidden by the grass growth, increasing the effective playing area within the course and ensuring that the aesthetics of the course are maintained. If necessary, the cart can be switched to manned operation to easily temporarily leave the track and return.

Example An embodiment of the present invention will be described.

Figure 1 is a schematic diagram of the golf course.
2 is the fairway, 2 is the teeing ground, 3 is the green, 4 is the bunker, and 5 is the administrative road around the course and the cart-only road.

In addition, FIG. 2 is a schematic diagram of a loop induction type cart, in which 6 is a pick-up coil provided at the front end of a three-wheeled or four-wheeled cart 7, 8 is one front wheel,
Reference numeral 9 indicates two rear wheels on the left and right.

When constructing a cart running path 12 consisting of three parallel rails 10 and 11 on which the front wheels 8 and rear wheels 9 of the cart 7 are placed within the fairway 1, the present invention uses a cart running path 12 as shown in FIGS. 3 to 7. Then, follow steps (1) to (8)
Let's do it.

(1) In the fairway 1, grooves 13 are continuously excavated along the cart running path construction line to approximately the same depth.

(2) In the groove 13, a roadbed 14 made of sand and gravel such as cut crushed stone is constructed so as to be continuous at approximately the same depth.

(3) Construct three concrete foundations 15 corresponding to the running lines of the front wheels 8 and rear wheels 9 on the roadbed 14 so that their upper surfaces are parallel to the fairway surface 1a, and A gap for draining water to the roadbed 14 is provided between the foundations 15.

(4) Mortar 1 on the concrete foundation 15 on both sides
For example, a concrete rail unit 1 with a length of 1 m is used as a rail made of a material that has a high coefficient of friction with the cart wheels and has sufficient rigidity.
7 are connected and fixed, and at that time, the rail unit 1
Mortar 1 is placed in the connecting hole 18 formed between 7 and 7.
9 to connect the rail units 17 together, thus forming the rail 11.

Similarly, mortar 16 is spread on the central concrete foundation 15, and concrete rail units 17' having a length of, for example, 1 m are connected and fixed, and at this time, the connecting holes 18 formed between the rail units 17' are Next, the rail units 17' are connected together by filling with mortar 19, thus forming the rail 10.

The rail units 17, 17' have upper and lower wheel running surfaces 20 and adhesive surfaces 21 that are parallel to each other at the same height, and have a cross-sectional shape that is stable in terms of self-sustainability. A groove 22 is formed in the running surface 20) along the longitudinal direction of the unit.

Both of these rail units 17, 17' are produced in large quantities at a factory.

(5) A guide wire 23 is installed in the continuous groove 22 on the upper surface of the rail 10 for causing the cart 7 to run in a loop-line guidance method.

(6) Top surface of rails 10, 11 (wheel running surface 20)
Then, if necessary, artificial grass 24 is adhered to cover the upper surface.

(7) Backfill the groove 13 portion around the rails 10, 11 to the top surface of the rails 10, 11.

(8) Grass 26 is grown on the surface of the backfill soil 25.

In the above configuration, the short rail unit 1
The roadbed 14 and the concrete foundation 15 are placed on the fairway surface 1a on both sides of the groove 13 so that the upper surface (wheel running surface 20) of 7, 17' is parallel to the fairway surface 1a and the height is the same or slightly lower. The rail units 17, 17' can be adhered to the concrete foundation 15 by performing construction based on the above and making fine adjustments using the mortar 16.

Therefore, the rail 11 connecting the rail unit 17
The rails 10 connecting the rail units 17' can be laid in correspondence with the undulations of the fairway surface 1a, and at the same level as the fairway surface 1a or slightly recessed. Furthermore, this work can be easily and reliably performed by excavating a wider groove 13 than the cart running path 12 and using factory-produced rail units 17, 17'.

Moreover, the rails 10, 11, mortar 16, and concrete foundation 15 are kept in place by their own weight as a whole. Moreover, the groove 13 portion around the rails 10 and 11 is backfilled and grass 26 is grown on its surface, and this grass 26 takes root in the backfilling earth and sand 25 and the soil around the groove 13. Since the grass 26 that has its roots in the earth and sand 25 further spreads its roots in the soil below the roadbed 14, the rail 1
0,11 has good integrity and stability, and is durable enough for long-term use.

As shown in the example of the rail unit 17, if cross-section defects 27 are provided on both sides of the unit, the backfill earth 25 enters the sections 27, which not only increases the stability of the rail but also reduces the weight. This will reduce the amount of concrete used. Additionally, a connecting hole 18 is provided between the rail units 17, and a mortar 1 is inserted into the connecting hole 18.
9 can further increase the integrity and stability of the track.

As described above, the rails 10 and 11 are laid in a stable manner, and the guide wire 23 is supported on the stable rail 10 via the groove 22, so that the cart 7 is guided by the guide wire and its travel is smooth. The line becomes constant, and the cart 7 can be firmly supported on the rails 10 and 11 that coincide with the running line, and can run stably without coming off the wheels. be able to. Moreover, the lawn 26 is integrated with the fairway 1,
In addition, the rail 1 exposed on the fairway surface 1a
Since the upper surface (wheel running surface 20) of No. 0, 11 is narrow enough to correspond to the wheel width, it is rare for a golf ball to rest on the upper surface during play, and there is almost no hindrance to play. However, the beauty of the course is not affected much.

Note that if artificial turf 2 is pasted on the upper surfaces of the rails 10 and 11, play can be continued even if a golf ball is placed on it. In addition, whether the artificial grass 24 is pasted or not, if the grass 26 grows, the grass 26 will be able to move the rails 1 located below the growing surface of the lawn 26.
Since the narrow upper surfaces of 0 and 11 are covered, the beauty of the inside of the course can be maintained reliably.

Figure 8 shows the rail unit 1 when the cart 7 has two front wheels 8 and the front wheel spacing is narrower than the rear wheel spacing.
7'A is a sectional view showing the installation status of the rail unit 17'A, and FIG. 9 is a perspective view showing the configuration of the rail unit 17'A.
7'A is formed to have a U-shaped cross section, and has a parallel upper surface as a wheel running surface 20, a hole 28 in the bottom, and a groove 22 in the upper surface of the bottom.

Even if this rail unit 17'A is used, the cart running path 12 is created in the same manner as in steps (1) to (8) above. Further, although the guide wire 23 is different from the above in that it is buried in the backfilling earth and sand 25, the guiding effect of the cart 7 is the same because the buried depth is shallow.

FIG. 10 is a sectional view showing the rail installation situation when the front wheel spacing of the cart is the same as the rear wheel spacing,
As is clear from this figure, the support unit for supporting the guide wire 23 can be laid in the same way as the rail unit 17. In this case, the support unit may consist of only the concrete foundation 15 and the mortar 16, but a short concrete support unit may be connected and fixed thereon.

Effects of the Invention As described above, the present invention allows a cart running path to be created within the course safely, reliably, and easily without interfering with play.

That is, on a golf course, by laying a plurality of rails at a certain distance from the guiding line so as to match the running line of each wheel of the golf course cart, the golf course cart can run unmanned on the rails. The magnetic field generated in the guide wire can be uniformly detected by the detection unit on the golf course cart side, and as a result, the steering of the golf course cart can be accurately controlled. Even if the rail is equivalent to the width of the wheel, the lateral G during unmanned driving,
It is able to sufficiently withstand loads such as vertical G and is restrained on the rails, allowing the cart to run stably and unmanned without falling off the rails. Even in the grass, the rails are buried so that the top surface is flat and almost at the height of the ground surface, and the rails support the weight of the cart as it repeatedly runs, allowing the wheels of the cart to directly touch the lawn. In addition to not interfering with the growth of the grass, the track is stable because the ground is less likely to loosen when combined with the grass, and the cart can run unmanned with less vibration without adversely affecting the growth of the surrounding grass. As a result, the golf clubs in the golf bag carried by the cart are less likely to be damaged by vibration, and furthermore, running resistance is reduced, the power consumption of the cart is significantly reduced, and the weight of the drive system can be reduced.

In addition, the rails are narrow and buried with their tops almost at ground level, and grass is grown between the rails and on the ground surface outside of them, so that the tops of the rails are hidden as the grass grows. As a result, the beauty of the course is further ensured, and the probability of falling and colliding with golf balls is extremely small and does not interfere with play, so there is greater freedom in creating running paths within the course without interfering with the effective play area within the course. Since the travel route can be laid out at a fairway or in a position close to the players, such as near the fairway, the time required for changing clubs etc. is reduced, freeing up time for Kiyaday to provide services to players, and allowing play to proceed smoothly and attracting more visitors. We can expect an increase.

Furthermore, since the top surface of the rails is flat and almost at the ground level, it is extremely easy to switch the cart to manned operation and temporarily leave the rails, then return again, if necessary, such as when a following party is overtaking. It is something that can be done.
