Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a self-propelled system for a kayak cart equipped with a prime mover for transporting golf equipment along the course at a golf course. This invention relates to a self-propelled Kyaday cart device that can be installed in

(Conventional technology) Kyaday carts installed at golf courses include
There are various methods, but the Kyaday cart, which runs on a monorail buried underground, is advantageous because it does not spoil the scenery of the golf course and is also suitable for automatic driving.

Below, the conventionally known monorail type cart (Japanese Utility Model Publication No. 53-149306) will be explained with reference to FIG.

This method is based on a monorail 41 buried underground.
is a concave groove consisting of a bottom wall portion 42 and a side wall portion 43, and a step portion 44 is formed in the side wall portion 43.
A flat rail wall 45 is placed on the stepped portion 44 to form a two-tier structure, upper and lower. A cover plate 46 is provided at the upper end of both side wall portions 43, and a slit 47 is formed in the center by the cover plate 46. Above, track wall 4
Drain ports 48 are partially opened on both sides of the drain 5. Kyaday cart is a loading platform for golf equipment 4
9 and a running section 50, and the running section 50 consists of wheels 51, a transmission mechanism 52, a motor 53, and anti-rolling wheels 54. The running section 50 is arranged inside the monorail 41 which is made of a groove.
The space defined by the track wall 45 and the bottom wall 42 serves as a drainage channel 55.

It is also known that fall prevention wheels are provided in contact with the upper and lower walls of the rail. (Refer to Japanese Patent Application Laid-open No. 52-91211).

(Problems to be Solved by the Invention) However, the above-mentioned known monorail type cart has the following problems.

In the known kyaday cart, since the running section 50 is disposed inside the groove, there is a risk that water falling from the slit 47 and dust such as dead leaves may enter the motor 53 of the running section 50. For this reason, the motor 53 is prone to failure, resulting in a lack of reliability in running. This hinders play in rainy weather, making it unsuitable as a golf course golf cart that needs to be used regardless of the weather.

Furthermore, the motor 53 itself may malfunction and requires periodic maintenance such as replacing parts, but in such cases, the running section 50 must be pulled out of the groove for repair or inspection. However, it was inconvenient in terms of maintenance. In particular, since self-propelled equipment such as a kayak installed at a golf course is often submerged in rainwater as will be described later, it is a very important issue to be able to easily repair and inspect the motor 53.

Next, in the above-mentioned known kayak, the slit 4 of the cover plate 46 provided on the upper surface of the side wall portion 43 of the concave groove.
Since the slit 7 is always open, water and dust such as dead leaves may enter through the slit 47 and cause malfunction of various parts. Further, the golf ball being played falls from the slit 47 into the groove, causing trouble in play. Furthermore,
There was also a risk that the golf ball being played would hit the cover plate 46 and irregularly bounce. In addition, since the cover plate 46 is visible, it spoils the appearance of the golf course. For this reason,
The above-mentioned known kayak cart could not be driven on the fairway.

Next, in the known kyaday cart, the concave groove is divided into a space in which the running section 50 runs and a drainage channel 55 as a two-stage structure, upper and lower, by the track wall 45, so that the installation work of the monorail is labor-intensive. This results in high costs. In addition, since the rail wall 45 is supported by the side wall portion 43 on both sides, it is easy to crack or break, and in order to avoid this, the thickness must be increased, so the installation work is also difficult in this respect. becomes difficult and costly.

On the other hand, there is also a known vehicle in which a rail is placed in the center of a groove, and a car that runs on the rail is provided with rubber covers extending from both sides of the groove toward the center to cover the groove. . (Tokukai Akira
50-141017, Utility Model Publication No. 54-23682).

However, in these known techniques, since the rubber cover is a horizontal surface, the golf ball may remain on the rubber cover, which may impede play. Therefore, the grooves are installed in the fairway. It had become impossible.

Furthermore, if the rubber cover is merely covering the groove, there is a risk that if the rubber cover is damaged, the golf ball may fall into the groove from the damaged or damaged portion.

In addition, in the above-mentioned known fall prevention wheels, since the fall prevention wheels are immovably fixed to the running body, strong vertical vibrations are applied to the running body, causing slippage of the running wheels, and causing damage to the running body. The drawback was that smooth running could not be achieved. Moreover, this had an adverse effect on the cargo placed on the traveling body, causing the cargo to collapse.

(Object of the Invention) The present invention provides the above-mentioned self-propelled device for a kayak cart that runs on a single track buried in the ground, which does not harm the scenery of a golf course by reducing the exposed surface to the ground surface. To eliminate irregular bounce of a golf ball, to prevent the golf ball from staying on the rail, and to prevent the golf ball from falling into the rail, thereby allowing the cart to run on the fairway. The purpose is to make it possible.

Another object of the present invention is to provide a self-propelled wheel-cart device that is less prone to breakdowns and that facilitates maintenance such as repairs and inspections.

Furthermore, the present invention makes it possible to drain water from a single rail buried underground with a simple structure, thereby further reducing failures and at the same time reducing material costs and installation costs. The purpose is to

Another object of the present invention is to prevent the vibrations caused by the anti-overturn wheels from being directly transmitted to the cart, thereby preventing the running wheels from slipping and the cargo from collapsing.

(Means for Solving the Problems) The present invention is characterized by the following configuration.

The cart consists of a cart having a loading platform placed on the ground, a bottom, a side wall, and a shoulder, and an opening whose width is smaller than the diameter of a golf ball is provided at the upper butt part of the shoulder. a flexible rail that is formed and buried so that the opening is at the ground level; and a flexible rail that makes the central part higher than both side parts and closes the opening of the rail from both sides so that there is an overlapping part. a running wheel that rolls on both sides of the bottom of the rail, an overturn prevention wheel that comes into contact with a shoulder of the rail, and a spring that biases a support part of the overturn prevention wheel toward the shoulder. , a guide wheel that comes into contact with the side wall of the rail, a vertical shaft that supports each of the wheels and supports the loading platform, a prime mover disposed on the loading platform, and a wrap-around transmission that connects the prime mover and the running wheels. A self-propelled device for a cart, comprising: a mechanism; and a groove formed by a step in the center of the bottom of the rail.

(Function) According to the cart of the present invention, the cart travels by transmitting the rotation of the prime mover to the running wheels through the wrap transmission mechanism.

Furthermore, the anti-falling wheels and guide wheels abut against the shoulders and side walls to ensure smooth running without falling, shaking or bending.

Even if the golf ball hits the rubber cover, it will not bounce irregularly, and even if the golf ball lands on the rubber cover, it will roll to both sides of the groove because of the slope, and the ball will roll to the next play. You can continue to do so. Furthermore, even if the rubber cover is damaged, it does not fall into the rail through the opening of the rail, and can be easily and easily picked up to continue playing.

Furthermore, when water enters the rails, it is collected in the grooves and drained away, so the running wheels do not run through puddles and run smoothly.

Furthermore, since the anti-overturn wheels are in contact with the shoulders of the rails, slips are prevented, and the vibrations of the anti-overturn wheels caused by running are absorbed by the springs.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Referring to FIGS. 1 to 5, the self-propelled device of the present invention consists of a cart 1 and one rail 2 buried underground. The cart 1 consists of a running section 4 of a loading platform 3, and a box 5 housing a prime mover (not shown) is provided on the loading platform 3. Furthermore, a mounting table 6 on which golf bags are placed is provided on the loading platform 3. The running section 4 includes a vertical shaft 7 hanging from the loading platform 3, a frame 8 fixed to the vertical shaft 7, a running wheel 9 and a guide wheel 10 rotatably provided on the frame 8, and a running wheel 9 and a guide wheel 10 fitted into the vertical shaft 7. The support member 11 includes a fall prevention ring 12 rotatably provided on the support member 11, and a spring 13 that biases the support member 11 upward. The prime mover and the running wheels 9 housed in the box 5 are wrapped around the transmission mechanism 1.
4, and transmits the rotation of the prime mover to the running wheels 9. Although the wrap-around transmission mechanism is shown as a chain-based transmission mechanism in this embodiment, it may include other means such as a timing belt.

The rail 2 consists of a bottom part 15, a side wall part 16, and a shoulder part 17, and an opening part 18 is formed in the abutting part above the shoulder part 17. A step 19 is formed on the bottom portion 15, and the step 19 forms a groove 20 in the center of the bottom portion 15. At the same time, when a flange 9A is formed on the running wheel 9, the flange 9A engages with the step 19. It has become a match. The anti-overturn wheel 12 is in contact with the inner surface of the shoulder portion 17 to prevent the cart 1 from being displaced in the vertical direction. Further, in this embodiment, the guide wheel 10 comes into contact with the side wall of the rising portion of the shoulder portion 17 to prevent the cart 1 from being displaced in the lateral direction. Shoulder part 1
The shape of 7 is not limited to the illustrated embodiment, and extends from the top surface of the side wall portion 16 toward the center.
It is sufficient if an opening is formed in the abutted portion. Further, the width of the opening 18 is made smaller than the diameter of the golf ball to prevent the golf ball from falling into the inside of the track 2. Here, the diameter of a normal golf ball is 42.67mm for a large ball,
The small ball is 41.15mm. The groove 20 is a drainage channel, and like a normal drainage ditch, rainwater catch basins are provided at predetermined intervals to allow drainage to flow out.

A cover 21 made of an elastic and flexible material such as rubber is provided on the shoulder 17 of the rail 2, and the opening 18 is covered by the cover 21. The cover 21 is sloped so that the central part is higher than both sides, and one side overlaps the other. When the cart 1 runs, the vertical shaft 7 opens the cover 21, and the cart 1 is not running, the opening 18
It is becoming more and more obstructed. The cover 21 is at the same level as the ground level of the golf course, and grass is grown on the cover 21. When a golf ball is placed on the cover 21, the golf ball will roll to both sides of the rubber cover 21 because of the slope.

FIG. 6 shows another embodiment of the guide ring of the present invention. In this embodiment, the guide ring 10' is rotatably provided on a support shaft 22 provided in the vertical direction on the frame 8, and The ring 10' abuts against the side wall 16 of the rail 2.

In each of the embodiments described above, various materials such as concrete, metal, or FRP are selected as the material for the rail 2.

(Operation) The operation of the traveling device for the cart 1 of the present invention configured as described above will be explained.

A prime mover (not shown) housed in a box 5 is rotated and stopped, and the rotation of the prime mover is transmitted to running wheels 9 via a winding transmission mechanism 14, and as the running wheels 9 rotate, the cart 1 runs. The running of the cart 1 is started and stopped by operating a remote control device or the like to rotate and stop the prime mover.

The displacement of the cart 1 in the vertical direction is prevented by the overturn prevention wheels 12 coming into contact with the inner surface of the shoulders 17 of the rails 2, and since the spring 13 is provided, the overturn prevention wheels 12 are prevented from displacing in the vertical direction. This prevents the running wheels 9 from slipping, and the vibrations generated by the anti-overturn wheels 12 are absorbed by the springs 13. Further, lateral displacement of the cart 1 is prevented by the guide wheel 10 abutting against the side wall of the shoulder 17 or the side wall 16.

Further, in a normal state, the cover 21 closes the opening 18 of the rail 2, but in a place where the cart 1 is traveling, the cover 21 is closed by the vertical shaft 7.
will be held. Therefore, rainwater, dead leaves, etc. are prevented from entering the inside of the rail 2, and the running of the cart 1 is not hindered.

Furthermore, even if rainwater enters the inside of the rail 2, the rainwater is collected in the groove 20 and drained.

Furthermore, if the golf ball falls onto the cover 21, it will not bounce irregularly.
It bounces like a normal fairway.

Furthermore, if the golf ball rolls and lands on the cover 21, it will roll and stop at a position away from the cover 21 because the cover 21 is inclined.

Furthermore, if the cover 21 were to be damaged, the golf ball would land on the opening 20;
Since the width of the rail 2 is small, the golf ball does not fall into the inside of the rail 2.

(Effects of the Invention) The effects of the present invention configured as described above are as follows.

Since the opening is covered with a flexible cover, it is possible to prevent rainwater and dust such as dead leaves from entering the cart without interfering with the running of the cart, and this also reduces the possibility of breakdowns. Furthermore, since the grass grows on the cover, the appearance of the fairway is not spoiled, and irregular bounces of the golf ball do not occur. Moreover, the golf ball will not fall into the inside of the rail. Therefore, there is no problem in installing the cart of the present invention on a fairway.

Since the running section disposed inside the rail does not include a prime mover and is only a winding transmission section, there are fewer failures, and since the prime mover is placed on the cart, maintenance is easy.

Since the structure is such that a groove is provided at the bottom of the rail for drainage, the installation work is easier compared to the known two-stage drainage channel, the cost of materials is also low, and the durability of the rail is improved. The durability of running equipment will also be improved.

Since the rubber cover is inclined so that the center is high and both sides are low, the golf ball does not stop on the rubber cover and does not interfere with play.

Even if the rubber cover is damaged, the golf ball will not fall into the inside of the rail from the opening of the rail at the damaged portion.

In addition, since the anti-falling wheel is brought into contact with the shoulder of the rail via a spring, the vibration generated in the anti-falling wheel is not directly transmitted to the cart, thereby preventing the running wheels of the cart from slipping. This also prevents the cargo placed on the cart from collapsing.
