Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is particularly directed to a concrete cart used for transporting golf bags, players, and carts at golf courses, or for carrying infants, etc. at amusement parks, for running on a fixed track. Regarding the cart trajectory block.

Conventionally, the carts used to transport golf bags, players, and other items along the course have been manned and driven by humans, and recently there have also been remote-controlled carts to reduce labor. There was one with an unmanned driving system.

Among these, the manned driving type had the disadvantage that the driving location was inconsistent, causing damage to the grass on the green by the carts, degrading the scenery and impairing the function of the fairway.

In addition, even for unmanned carts, it was necessary to create asphalt pavement etc. to ensure a constant running track. As a result, the landscape is severely damaged and the lawn may be damaged.Furthermore, the falling impact of the golf ball is strong and the rebound is strong, causing the golf ball to travel irregularly and hinder play. Moreover, since it is not possible to install a running track for transporting carts in the relatively central part of the fairway, there are restrictions on playing, such as having to change clubs according to the progress of the play. It was hot.

Furthermore, the running tracks used in conventional unmanned driving systems are built by casting on site, which requires a lot of time and money. It became difficult to do this, and it was difficult to obtain a uniform running trajectory.

Furthermore, prior to this application, a method was proposed (Japanese Unexamined Patent Publication No. 59-27002) in which a cart running path consisting of a plurality of parallel tracks on which cart wheels are built is created within a course. In this method of constructing a cart running path, since a plurality of independent rail units are individually connected as multiple parallel track members, the work required to create the cart running path is complicated and takes a long time. have.

The present invention provides a concrete cart track that allows carts to be run on a fixed track at a golf course, etc., and which enables efficient installation work at the golf course, etc., and which can form a running path with little displacement after installation. The purpose is to provide block units and orbital blocks.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 3.

1 is a single track block, and this single track block 1 has three parallel track members 3a, 3b, 3c formed relatively narrow and having a smooth surface 2 on the upper surface.
and four connecting rods 4 at the front and rear for connecting the track members 3a, 3b, and 3c.

The reason why there are three 3a, 3b, and 3c in this embodiment is because the cart A is a three-wheeled vehicle type. 5
are openings surrounded by the track members 3a, 3b and the connecting rods 4, 4, and the track members 3b, 3c and the connecting rods 4, 4, respectively. Planting soil 6 for growing plants is accommodated.

Reference numeral 4a denotes a concave portion formed on the upper surface of the connecting rods 4, 4; 4, 4 in order to reduce the volume of the connecting rods 4, 4;
Although the area covered by the planting soil 6 is increased by providing the covered portions 4a, 4a, it is not necessary to provide these covered portions 4a, 4a; 4a, 4a; The upper surface of 4 may be formed into a flat surface to increase strength.

Reference numeral 7 denotes a guide wire to be fitted into a groove 8 provided in the center of the upper surface of the track material 3b located at the center, and this guide wire 7 is buried in the soil at a depth of 3 to 5 cm underground. Or, by being exposed to the ground surface, an oscillator in the central control panel sends a low frequency current to generate a band-shaped magnetic field in the induction wire 7, and a pick-up coil C as a magnetic sensor attached to the front of the cart A generates a band-shaped magnetic field. When the cart is detected, a servo motor is activated so that the cart runs along the center of the smooth surface 2 of the track material 3b, and the cart is made to run under unmanned remote control. Reference numeral 8a denotes wide portions provided at the front and rear ends of the groove 8. These wide portions 8a, 8a make it easy to fit and connect the guide wire 7, and prevent external vibrations after the guide wire 7 is installed. This is to absorb expansion and contraction due to temperature. Reference numeral 9 denotes a positioning hole formed on the side of the connecting rod 4, which is one end surface of the raceway members 3a, 3c. Protrusions 10, 1 provided on the side of the connecting bar 4 that becomes the end surface
By inserting 0, the single track block 1
are being laid continuously.

11 is for connecting the single orbital block 1,
These are bolt insertion holes drilled in the connecting rods 4, 4; 4, 4, and by inserting a connecting bolt 12 into this bolt insertion hole 11, the track blocks 1 are connected continuously. .

One embodiment of the present invention has the above-mentioned configuration, in which the single track block 1 is connected to crushed stones as a foundation that are first excavated into the soil of a golf course and tamped therein as required. and lay it.
At this time, the installation position of the single track block 1 is determined by inserting the protrusions 10, 10 provided on the rear surface of the preceding single track block 1 into the holes 9, 9 provided on the front surface of the single track block 1. .
Then, by inserting the bolts 12 into the overlapping bolt insertion holes 11, 11 of the preceding track blocks 1, 1 and screwing the nuts 13, the preceding track blocks 1, 1 are connected. , groove 8
The guide wire 7 is fitted inside.

Thereafter, the entire track block 1 is covered with planting soil 6, and plants such as Western grass 14 are planted to lay the track of the cart A in the soil of the golf course. At this time, since the guide wire 7 is covered at a relatively shallow depth, for example, 3 to 5 cm from the ground surface, a low frequency current is generated in the guide wire 7 by the pick-up coil C by flowing a low frequency current with an oscillator from the central control panel. The cart A is controlled by an unmanned remote control so that the front wheels move on the center track material 3b, and the two rear wheels simultaneously move on the two outer track materials 3b.
You can run the course by running on a and 3c. Moreover, since the entire track block 1 is covered with planting soil and Western grass 14 is planted,
The scenery of the green is not spoiled, and cart A is equipped with three track materials 3 as specified above.
Since it runs on top of a, 3b, and 3c, it does not damage plants such as western grass, and it is also suitable for golf.
The ball will not bounce unnecessarily.

Stopping points are set up at important points near the teeing ground of the hole, along the edge of the green, on the fairway, etc., and Cart A is stopped, so the player or teammate does not have to walk long distances from one course to the next. , you can select the desired club and play. Furthermore, if the entire track block 1 is buried in relatively thin soil so that only the track material 3b having the guide wire 7 is exposed, this exposed part will be covered with the western grass, so the above construction is not necessary. As in the previous example, the scenery of the green is not damaged.

Furthermore, the planting soil 6 in which the Western grass 14 is to be planted is housed in the openings 5, 5 provided in each individual track block 1, and has water permeability and air permeability, making it possible to grow plants such as the Western grass 14. This makes Western Grass 14 suitable for growing even on courses with many ups and downs.

What is shown in FIGS. 4 and 5 is the second embodiment of the present invention.
This is an example, and includes two parallel track members 3a, 3 made of concrete with a guide wire 7 pivotally attached to either of them.
This embodiment differs from the previous embodiment in that b is connected with connecting rods 4, 4, which are separate from the above, using bolts 15, thereby forming a single track block 1' for running the four-wheeled cart A. . In addition, the connecting rod 4',
4' may be made of concrete or metal.

The cart track block of the present invention is either entirely buried in relatively shallow soil or embedded in a relatively shallow mouth such that only the track material having guide wires for guiding the cart is exposed. Plants are planted so that the carts can run on a fixed path, so there is no damage to the scenery, the carts do not run on the grass on the course, and the grass is not damaged, and it can be laid on fairways. It can be installed in any location. In addition, individual track blocks can be mass-produced in factories with pre-standardized dimensions and shapes, which reduces costs, greatly reduces the need for on-site casting, and facilitates installation work.

With the structure of the present invention, the plurality of track members are integrated into a single track block by a connecting rod, so positioning between each track member, which is troublesome in the conventional structure in which the plurality of track members are each independent, is eliminated. unnecessary,
Moreover, the connecting rod is provided with a connecting means for connecting the single track block, and the connecting rod equipped with the connecting means allows installation of a plurality of track materials and single track blocks in an extremely short time, accurately and efficiently. Moreover, the provision of the connecting rod prevents the positional displacement of multiple track materials, maintains the installed track in a stable state for many years, and has the effect of simplifying repairs. has.
