Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a running path for golf carts running within a golf course.

(b)) Prior art As a technology prior to the present invention, Japanese Patent Application Laid-Open No. 61-113905
There is a running path for golf carts described in Kouai No. 1. In the golf cart running path described in the bulletin, the golf cart's front rudder wheels and a pair of rear steering wheels move on a plane at the same height as the track block that forms the running path in a 1+Z shape.

Because golf carts move on the same plane, when they stop, their center of gravity moves forward due to inertia, which reduces safety due to the lifting of the rear wheels and reduces braking force.
This problem was especially noticeable on downhill slopes and curves.

(c) Problems to be Solved by the Invention The technical object of the present invention is to provide a golf cart running path that improves the safety and stability of running and stopping golf carts.

2.) Means for Solving Electrical Charge The present invention provides a base body on which a front steering wheel and a pair of rear running wheels of a golf cart move along the golf course.
However, the problem is solved by means of forming the central portion of the base body, where the front steering wheels move, higher than the both side portions where the pair of rear running wheels move.

The base plate may have a track groove formed in the shape of a rail only in the portion where the front steering wheel and the rear running wheel move, or
It may be formed like a single plate.

The material for forming the substrate body may be concrete, ceramic, etc., or synthetic resin.

The substrate body may have no holes, may have small holes through which rainwater can pass, or may have holes large enough to allow grass to grow.

(e) Operation In the present invention, the center of gravity is located in the rear compartment with respect to the moving direction by moving the n steering wheels at a higher position than the rear running wheels.

(f) Example drawings show the specific structure of the present invention, and FIG.
3 is a plan view of the running path 2, and FIG. 4 is a longitudinal sectional view of the substrate body 3, which is a member forming the running path 2.

The golf cart 1 generates electromagnetic waves from a guide wire 5 wired along a golf course at the front lower part of the main body, detects the electromagnetic waves with a mental detection coil, and automatically travels along the guide wire 5. Stopping and deceleration of the golf cart 1 are automatically performed by detecting magnets disposed at appropriate locations on the reverse path 2 using a magnetic detection coil formed on the bottom surface of the main body. Also golf cart 1
Zero travel Φ stopping can also be performed wirelessly using a signal from a transmitter held by the player or caddy.

The golf cart 1 in this implementation structure has an internal capacity of 900 wR.
1 car length is 1600111. The vehicle height is between 895 and the vehicle weight is 1.
30kq-, can load up to 4 golf bags 6,
Usually it weighs about 200 pieces.

The running speed of the golf cart 1 on flat ground is a high speed of 6, /H, and a low speed of 3K, /H, the uphill and downhill angles are 23 degrees at maximum, and the turning radius is 1.5 m. The number of wheels is three special wheels, including a pair of rear running wheels 7 and a pair of front steering wheels 8. r
) The distance between the front and rear axles of the u steering wheel 8 and the rear running wheel 7 is 63
0171! The front steering wheel 8 has a wheel center left and right distance of 8.
1 gate, rear heavy running wheels 70, distance between wheel center left and right is 700 m, distance between wheel inner surfaces is 606 m, distance between wheel outer surfaces is 794 m, and front steering wheel 8 size is 2.5-4.
This shows a vehicle with a width of 2.5 inches and an inner diameter of 4 inches, and the outer diameter of the front steering wheel 8 is 228 wheels. The size of the rear running wheel 7 is 3,5-5, 3.5 inch width and 5 inch inner diameter, and the outer diameter of the rear running wheel 7 is 298M and 307M.
There are two types of gardens. It should be noted that each of the above-mentioned dimensions is given as an example and can be implemented with various changes.

Since the distance between the outer surfaces of the rear running wheels 7 is 794,
The width of the reverse road 2 is determined from 79Qffim to 1, considering the fact that there will be no problem in running even if the rear regular wheels 7 extend slightly beyond the running road 2, and considering the construction, aesthetics, and stable running of the golf course.
300u is suitable. Therefore, the width of the substrate body 3 constituting the retrograde path 2 is naturally from 790M to 1300M! It will be formed in the range of fl, and the optimal medium size is 800M.
It is. Reverse route 2 is constructed along the golf car Vc.
Since it is necessary to adapt to straight lines, curves, uphill slopes, downhill slopes, and undulating ground, the shorter the length of the board 3, the more detailed the change can be handled, but a larger number of boards is required. Therefore, in this structure, the outer shape is formed into an isosceles trapezoid shape so that the single substrate body 3 can correspond to the II line and the curve of the retrograde path 2. is 566 m, and the wiring portion of the guide wire 5 is 59 m (1 m), but each dimension can be determined based on the design, !i term, and how large the radius of the curve is.

The substrate body 3 is molded from a synthetic material having strength and durability as the running path 2, such as light resistance, water resistance, and friction resistance. The substrate body 3 includes a bonded outer frame 11 and left and right outer frames 1 that form an outer shape.
2, and an inner crosspiece 13 formed between the joint outer frame 11 and the left and right outer frames 12. The inner rail 13 is parallel to the left and right outer frames 12 on both sides and in the center where the rear running wheels 7 and front steering wheels 8 move, and is diagonally formed between the second inner rail, the joined outer frame 11, and the left and right outer frames 12. It is formed from 3 inner bars. Joint outer frame 1
As shown in FIGS. 1 and 4, the second inner rails of the inner rail 1 and the inner rail 13 are formed in an arcuate shape with the center higher than both sides. Joint outer frame 1
In order to maintain the bow shape of the second inner crosspiece of the inner crosspiece 13, the lower end surface of the first inner crosspiece of the inner crosspiece 13 is as shown in FIGS. 1 and 4.
It is made to protrude downward so as to be located in the same horizontal plane as the lower end surfaces of the left and right outer frames 12.

On the upper surface of the base body 3 on which the golf cart 1 runs, as mentioned above, the central part where the front steering wheel 8 runs is formed higher than the both side parts where the running wheels 7 follow, so that the weight of the golf cart 1 is higher. A stable running surface with strong strength can be obtained against deformation of the running surface as the running path 2 over time due to the running of the cart 1. Also, because the front steering wheels 8 run on a higher surface than the rear wheels 7, the center of gravity of the golf cart 10 is slightly shifted from the rear wheels 7.
By moving to the side, the base plate 3 is prevented from slipping, and the driving force is efficiently transmitted to the running path 2, allowing stable running. Furthermore, the forward leaning when braking is applied to the golf cart 1 is alleviated, and a stable telekinetic braking force can be obtained.

As shown in FIG. 4, unevenness is formed on the lower surface of the second inner rail of the inner rail 13 of the substrate body 3 to prevent it from shifting from the ground. Assuming that the substrate body 3 is an isosceles trapezoid, by inverting it 180 degrees and joining it as shown in Fig. 3, it is possible to form a straight line 7-hike Raku 2, and if it is joined without inverting it, it can be made to travel in a curve. With the dimensions described in 1fI, a curved running path with a radius of about 10 m can be formed. The substrate body 3 is joined to the outer frame 11
They do not need to be in contact with each other, and may be joined with a slight gap between them. In this case, the radius of the curved travel path can be adjusted as appropriate within a range that does not impede the travel of the golf cart i. The guide wire 5 is formed on a coaxial cable, and is held on the substrate body 3 by a holding portion 14 formed on the inner crosspiece 13. Holding part 1
Although 4 is formed by a notch formed in the inner crosspiece 13, it may be formed by a two-pronged holding protrusion or a groove.

Next, one method of creating the running path 2 using the substrate body 3 will be explained. A roller is applied to the width of the substrate body 30 in a part where grass is grown and forms a running path 2 of the nine-land IIiligI to compress the grass and form a surface that is one level lower than the surrounding grass. The substrate bodies 3 are sequentially placed and arranged on the lowered compressed grass, and the substrate bodies 3 are temporarily fixed to the ground 2 with U-shaped screws or the like. Thereafter, a hole is made using a jig or a machine at the center of the nine sections surrounded by the inner crosspieces 13 on both sides and the central portion adjacent to the outer joint frame 11, or the inner crosspiece 13, the outer joint frame 11, and the left and right outer frames 12. Then, a hardening fluid 16 such as cement is poured into the portion surrounded by the inner crosspiece 13 and the perforation 15. When the poured curable fluid 16 hardens, it fixes the substrate body 3 to the ground. Therefore, this method of construction does not require any separate parts such as nails or bolts to fix the substrate 3, and can be carried out by simple construction such as drilling holes and pouring the hardening fluid 16. Further, although the floating earth of the substrate body 3 is sufficiently achieved in the above-described structure, in order to make it more reliable, protrusions 17 are formed on the inner crosspiece 13 and the joint outer frame 11 as shown in FIG. It's good to do that.

In addition, it is better to compact the grass with a roller and cut it down to the thickness of the basket board 3 (20 gates in this structure), and then install the board 3.

After removing the grass and exposing the ground y,
After the substrate body 3 is installed, the substrate body 3 may be half-filled with sand, and then grass seeds may be sown to grow grass.

Regarding the connection and fixation of the board body 3, is there a sleeper member near the connection? The substrate body 3 may be fixed to a facility and fixed to a sleeper member using tapping screws, bolts, or the like. Guide wire 5
is fixed to the substrate body 3 and wired, but it may be wired directly in the ground or buried, or it may be inserted into the pipe body and wired. The substrate body 3 may be formed with a holding portion 'J&: for holding not only the guide wire 5 but also all of the communication wires.

In order to prevent the golf cart 1 from running, the substrate body 3 is
The upper surfaces of the joint outer frame 11, left and right outer frames 12, and inner crosspiece 13 formed with gold may have anti-slip irregularities f&:Ijll-, and the irregularities may be a large number of pin protrusions.

Left and right outer frames 12 of the portions of the substrate body 3 where each wheel 7.8 runs
The upper surfaces of the second and third inner rails of the inner rail 13 placed between the first inner rails of the inner rail 13 are concave toward the center of the running surface of each wheel 7.8. By forming recesses corresponding to ruts in advance, the golf cart 1 is automatically corrected so that it does not deviate from the path 2.

The unstructured running path 2 is constructed by attaching the golf cart 1dEfi board with the inner crosspiece 13 of 3, so that each wheel 7.8
The weight of the golf cart l is not applied through the substrate body 3, and grass grows in the area surrounded by the joint outer frame 11, the left and right outer frames 12, and the inner crosspiece 13 of the base plate 3, forming the running path 2. This prevents the golf course from becoming difficult to distinguish from other parts of the golf course and spoiling its aesthetic appearance.

(G) Effects of the invention The present invention provides a method for making the center of the Ama-gyo path higher and lower on both sides.
By using the substrate, Ictfe can be easily formed, and the golf cart can be stably stopped.
