Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an improvement of a running path along which a guided golf cart runs along a course of a golf course.

(b) Prior art At golf courses, alternating current is passed through a single induction loop buried approximately in the center of the cart running path along the course, and the alternating magnetic field generated by this is induced as shown in Figure 1. It is detected by a detection coil b attached to the front of the dynamic golf cart a, the induced electromotive force is amplified, and the difference between the two induced electromotive forces causes the servo motor to rotate forward or backward, changing the direction of the caster c. , the cart is guided along a guiding loop. d is the driving wheel.

Conventionally, this running road has two methods: the entire surface is paved with concrete or asphalt, and as shown in Figure 2, only the parts where the drive wheels and casters pass are lined up with flat concrete blocks e, f, and g, and no blocks are laid. Grass was planted in some areas.

The former cart path has a paved road about 1.5m wide that is rough along the course, and as an improvement to this, the latter cart path has three or four thin blocks lined up only in the area where the wheels pass, making the surrounding grass a little more uneven. It's hard to stand out. However, both routes are covered in snow and ice during the winter, and even though it is possible to play golf, there are places where the routes remain frozen forever due to the shade of mountains, etc. Since the carts run unmanned, the road surface The situation cannot be determined, and if the wheels start to slip when braking or making a sharp curve, the servo motor will not be able to control the vehicle, and the vehicle will deviate from the induction loop and become completely uncontrollable. Alternatively, the cart itself may fall off the running path. Also, on an uphill slope, the vehicle may not move forward due to slippage.

(C) Purpose This invention improves the drawbacks of the conventional products mentioned above, and aims to provide a running path that is less noticeable to players, prevents wheel slippage, and allows carts to run safely and reliably. did.

(D) Structure In this invention, grooves are provided on the upper surface of the blocks that constitute the driving wheels of the cart and the running parts of the casters. In a guided golf cart running path where the running part of the main drive wheel and the running part of the caster between which the casters run and are provided with the guidance loop are each constructed of blocks continuously laid in the ground. A friction groove is provided on the upper surface of each block constituting the running section, and the groove is open to the side edge of the block and serves as a running path for the guiding golf cart.

(e) Examples Examples of this invention will be described below in detail with reference to the drawings, but this invention is not limited to the following examples.

FIG. 3 shows the running path of this invention, which consists of running parts 1, 1 of the drive wheels of the guided golf cart on both sides and a running part 2 of the casters between them, and the ground is exposed between them. Both running sections 1, 1, and 2 are constructed by blocks laid continuously in the ground. Frictional grooves 3 are provided on the surface of each of the running parts 1, 1, 2 so as to be perpendicular to the direction of the running path, and each of the grooves 3 is open to the side edge of the block. The grooves 3 are provided to perform a frictional function when the guided golf cart runs, and to ensure that the drive wheels and casters run on the running section without slipping. In addition, by opening the side edges of the blocks, water that has reached the grooves 3 can be smoothly discharged to the ground.
No water is left on 1 and 2 to prevent freezing, etc. Furthermore, the open structure at the side edges serves to guide the grass planted on the ground into the groove 3, and when the grass is introduced into the groove 3, the running parts 1, 1, 2 further move. It becomes difficult to attract attention. It is also conceivable to configure the grooves 3 to be quite deep and to directly plant grass within the grooves 3. From the above point, the traveling part 1,
Grass may be planted on the ground on both sides of the running section 1 and between the running section 1 and the running section 2. Also, if you paint the blocks in a color similar to that of grass, such as green, it will be even harder to see. The running part 2 has a groove 4 in the center, and this groove 4
An induction loop 5 is provided inside.

FIG. 4 shows another embodiment of the running section 1, in which the grooves 3 are provided in an intersecting manner.

The running path of this invention may be provided continuously around the entire circumference of the course, or may be provided, for example, on a steep slope or in a shaded part of the course where carts are likely to slip.

(f) Effects This idea is structured as described above, so
The cart can be driven safely and reliably without being seen by many people, and without slipping. In particular, because the grooves are open at the side edges of the block, the grass that enters the grooves directly covers the running area, and there is no need to worry about freezing because the water is well drained and no water remains on the running area at all times. It's something that doesn't exist.
