Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a self-propelled device for a self-propelled cart equipped with a motive wheel for transporting golf equipment, players, etc. along the course at a golf course. be.

(Prior art) Conventionally, as a self-propelled cart for carrying equipment, players, etc. at a golf course, a mole rail type consisting of a single track has been proposed, but this method raises the rail higher than the ground. Alternatively, a large trench (for example, about 2jrcm) was dug and the rail was installed in the trench so that it did not protrude above the ground. In addition, even if a temporary U-shaped groove is buried underground, the exposed surface to the ground is wide, so the goal may rush into the U-shaped groove and be lost, or the scenery may be spoiled, so the course is far away. We had no choice but to install it inconspicuously on the outside of a distant rough area. For this reason, caddies and players spend a lot of time and effort carrying the golf club back and forth long distances to take it in and take it out, and sometimes they are too lazy to do this and end up losing their score by graying with the wrong club. This not only detracts from the interest of play, but also extends the round time, which in turn limits the number of players allowed to attend. Also, if the ball is close to this rail, it will be obstructed by the rail high above the ground or the wide 11σ groove, causing the goal to bounce back and causing unexpected personal danger, or causing problems such as having to drop the ball. There were also many poisons that were undesirable for progress. Furthermore, it gives a sense of discomfort to the scenery of the golf course where you can enjoy the natural scenery. Therefore, in order to eliminate this, it was inconvenient and inconvenient to install it at a point far away from the course or to hide it by planting trees.

Also, electric carts themselves are heavy (approximately 551st place)
Furthermore, a person is required to operate the cart, and self-propelled carts on the fairway seriously damage the lawn, so it is necessary to install a concrete or asphalt paved path with a width of Jm specifically for electric carts. . This is also the same as in the case of the previous statement e, and not only is there a big downside to holding it further away (sometimes as far as 30 to 100 meters), but the zor often falls on this path, and the goal is much more difficult than expected. Shipley, who made an illegal pound that exceeded his goal and couldn't find the goal, seriously lost interest in Shipley, who flew out of bounds. In addition, a recently proposed electromagnetic induction type cart, which can be called an unmanned self-propelled electric cart, has an electromagnetic induction system installed on the concrete paved road (width /,!; m) on which the cart should run. This is a system in which a cable is buried, the magnetic field generated by the cable is detected by a sensor to determine the direction, and the cart runs unmanned by a remote device, but this method also has the same drawbacks as the electric cart mentioned above, so it is preferable. isn't it.

As a cart that does not have these drawbacks, there is an old hand cart that has two left and right wheels and is supported by the hands. It can be supported by the hand so it won't fall over, and it's lightweight and doesn't cause much damage to the grass, so it's still widely used on relatively flat golf courses, but it doesn't matter whether it's pushed by the player or the caddy. The labor force is large, and in recent years due to a shortage of caddies, nine bags (weighing about 1 Ioh) are often transported on seven carts. A total of 4! ;Ky is around Ky, the rotation of the wheels becomes heavier and the lawn is more frequently damaged. Especially on uphill slopes, play is delayed, and the caddy's service deteriorates, including the sanding of Dedette, which is a problem at golf courses. It has become the seed of However, the golf course in Japan has many ups and downs, and when carrying equipment on this course with a hand cart, it is difficult to move along with the players, which may delay the round and reduce the comfort of the chypre. Of course, it was completely impossible to transport the player.

At golf courses, wear and tear on the grass, which is the lifeblood of play, is the most troubling issue, and preventing this as much as possible is a top priority, but unfortunately automatic transportation devices have various deficiencies and there is no optimal one. Ta. However, the biggest cause of lawn damage caused by levers was the large weight of the carts. This is clear from the fact that the above-mentioned lightweight push cart caused almost no damage to the lawn. However, conventional carts were all made of metal and were heavy as described above. However, as mentioned above, it is preferable to lay rails on the fairway so that the cart can run on its own without setting the cart conveyance path far from the fairway.Although it is preferable to place the cart on the fairway so that the cart can travel on its own, in order to avoid damaging the lawn, it is preferable to install rails on the fairway. It is conceivable that the running wheels run on the U-shaped groove, but for this purpose, the width of the running rail needs to be at least 20 steps at a time, and therefore it is necessary to form a wide flange on the U-shaped groove. The gap between the flange part and the center part (the part through which the vertical shaft connecting the cart and the equipment in the rails passes) is at least 30. Because of this, it would be difficult to sufficiently hide it even if it was covered with artificial turf or the like, and the graying would give a somewhat strange feeling.

In addition, since the K runs on the top of the rail, the full load of the cart and equipment is applied to it, so it must be made strong enough to accommodate this. There is also a need to make the U-shaped groove portion that supports the structure strong. Therefore, the track φ itself becomes large and the lightning fleas also become large, which is not preferable from the viewpoint of handling and cost.

(Problems to be Solved by the Invention) The present invention aims to reduce the exposed surface to the ground as much as possible in the above-mentioned self-propelled forestry using underground single-track carts, thereby impairing the scenery of the golf course. There is no change from the lawn, such as the pound of sol, and there is less sideways holding, which saves labor and time.
The rails were made thin and lightweight, even though they could withstand the heavy loads of carts and equipment.

(Means for solving the problem) The present invention has a narrow cross-sectional shape that is buried at the same level as the ground surface (this can be installed not only in rough areas but also in the center of the course, ie, within the fairway, without hindering play). It is bottle-shaped, and the spacing between the bottle eyes is 33 degrees, which is enough to prevent a golf course (small diameter, straight fl'l/m*) from falling, especially when it comes to the surface. The thickness of the bottle opening is 'l - 3' m, and the width of the exposed surface including the gap is approximately! ;! The width of the inside and outside (approximately the width of a golf ball) is approximately 730 mm, and the total width of the part buried underground is approximately 730 mm.
A large number of narrow-mouthed bottle-shaped cross-section rails with a wide configuration at the front and back of the wing are connected, and these are buried in an endless manner following the course of a golf course, with the bottle mouth at approximately the same level as the ground surface. Furthermore, at the mouth of the bottle, which is at the same level as the ground surface, a cover such as movable artificial grass or rubber plate, which covers this and the gap and has the same elasticity and color as the fairway grass, is installed. The sides are attached so that they overlap on the gap.

(Example) Next, an example of the present invention shown in the drawings will be described in detail.

Reference numeral 1 denotes a narrow-mouthed, bottle-shaped rail in cross-section, which is a single rail type and is laid at approximately the same level as the ground surface along a golf course, and the bottom part 2 and shoulder part 3 have a bottom inner surface 4 and a shoulder inner surface 5 that are both horizontal. Although it is preferable that the bottom inner surface 4 be V-shaped and the shoulder inner surface 5 be a chevron-shaped inclined surface, as shown in the illustrated example, a mouth portion 6 is formed next to the shoulder portion 3. Therefore, the bottom part 2 is loaded with the full weight of the cart, which will be described later, and the circumferential part 3 is loaded with a load to prevent the cart from falling over, so it should have a strength (for example, thickness) that can handle these loads, and the other parts will maintain their shape. For example, the thickness is as thick as possible.
Therefore, the exposed part of the mouth part 6 also includes the space part 6 as described above! rOrmn or less.

Preferably, a molded article made of F, R, and P is preferred because it is lightweight, strong, and has excellent weather resistance and corrosion resistance. Also, on the upper end surface of the mouth part 6, that is, the exposed surface part, a flexible rubber plate or artificial turf made of the same elasticity and color as the grass is attached, and its sides are slightly above the space 6' from each other. A cover 7.7I is provided to prevent the infiltration of soil, sand, rainwater, etc. by opening the gap 6' with a sharp edge, and to open the overlapping υ when the cart passes.

The cart 25 is mounted on a plate-shaped base 8 in the front-back and left-right directions, and has a mounting table 9 for holding a luff bag (not shown) in an inclined state with a uniform load, and a player, etc. as required. Electricity is distributed to chairs, etc. on which people sit.

Therefore, when viewed from above, each fffllIi table is arranged in a cross shape so that the total load is almost averaged, and a back plate 10 that is held in an inclined manner with respect to each mounting table 9 is connected to a plurality of supports 11 and These are books connected by stays 12. Note that it is preferable that at least the base body 8 is formed of F, R, and P.

A connection 61+13 is provided on the base body 8, protrudes from the lower surface, and is pivotally connected to the vertical shaft 15 via the pivot 14. Vertical axis 1
5 is fixed to the frame 16 and has a elastically slidable goth 18 inserted therethrough by means of a spring 17. Shafts 19 are formed on both sides of the base 18 in a cross shape with respect to the vertical axis 15, and fall prevention wheels 2 are attached to each of the shafts 19 on both sides.
0 is rotatably inserted, and is elastically abutted against the shoulder inner surface 5 of the shoulder 3 of the rail 10 by the spring 17. A drive shaft 2) located in the front-rear direction of the fall prevention wheel 20 and rotatably supported by the frame 16. 2)
A driving wheel 22.22 and a running wheel 23.23 running in contact with the bottom inner surface 4 are keyed to this, and a cheno 24 that rotates around the driving wheel 22. It travels via a prime mover 26 that is decelerated and rotated by a prime mover such as a reversible motor installed above.
is reversibly driven, and the cart 25 moves by itself.

A drive side consisting of an upper VL, running wheels 23, 23, etc. is provided on one side of the cart 25, and the other side has almost the same configuration as this #shaft side, and the anti-overturn wheel 20 is provided vertically as above. It is slidably supported by a shaft 15 and elastically supported by a spring 17, and rotates while being pressed against the inner surface 5 of the shoulder portion of the rail 1. And the shaft 2)', 2) attached to the frame 16 before and after this
The driven wheels 23', 23' rotatably fitted in the rail 1 rotate in contact with the bottom inner surface 4 of the rail 1.

The vertical shaft 15 is swingably connected to the connecting shaft 13' by the pivot 14, and the connecting shaft 13' is connected to the cart 2.
A thrust bearing 28 is attached to a support 27 configured in
It is possible to freely rotate about the connecting shaft 13' and the vertical axis 15 via the vertical axis, that is, this vertical side can swing and rotate.

Incidentally, each of the driving wheel 23, the driven wheel 23', and the anti-fall wheel 20 is formed with a flange portion 29 #29' and 30, 30'. Matching step 4'.

5I may be provided to make the traveling guidance of the cart 250 even more certain.

(Function) A golf bag or a player is placed on each mounting table 9 or a chair (not shown) formed on the base 8, and each bag is placed on the back plate 10 and tilted to stably hold the band, etc. Fix it with. When the prime mover on the base 8, such as a reversible motor, is rotated by a remote control or the like and the running wheels 23 and 23 are rotated via a transmission system such as a chain 24, the cart moves to t1! ``The cart moves on its own at a speed slightly faster than a person's walking speed, and at the approximate ball hitting position, the cart stops and plays using something like the remote control or a beam switch, and in this way, courses are played one after another. Therefore, at the curve point of the rail 1, the driven side of the driven wheel 23- rotates by the thrust bearing 28, so it runs smoothly, and the flanges 29° and 30 prevent it from overturning.
The flange part 30 of 20 also provides good text guidance, and if the cart 25 falls over due to terrain etc., it will prevent it from falling @20
fi% inner surface 5 K%+ <The contact prevents the vehicle from falling, and the spring 17 strongly presses the two wheels 20, 23, 23' between the inner surface of the chest 5 and the inner surface of the bottom portion 4, making running smooth and eliminating running noise. It is something that can be obtained and run. Incidentally, it is thought that dirt and earth and sand may have entered and accumulated at the bottom of the rail 1, but this is removed by making a suction-type lightning cleaner run on its own along the rail. In addition, in particular, place a place in the center of the V-shaped bottom surface in the shape of IfL, and place dust and
Sediment may be collected and cleaned by means of demolition, and water may be drained out through depressions in the terrain or through water basins.

By cleaning the remains at night, the cart runs more stably and smoothly.

(Effects of the Invention) As described above, in the present invention, since the running weight and the driven wheel are accommodated in the rail and run, the entire load is applied to the bottom of the rail, so it is only necessary to make this part strong. Since no load is applied to the mouth part, it can be constructed thinly, and the exposed surface that appears on the lawn becomes a thin rut, making it difficult to discern its existence.Furthermore, since the wheels are not visible on the outside, the cart rolls over the lawn as if it were running on the lawn. It looks as if it is sliding, and it is possible to fly the fly over the shortest distance on the fairway, which was previously unthinkable.It also does not damage the landscape or the most important fairway grass, and the rails are cheaper. It is also lightweight in terms of handling, making it innovative for transporting bags at golf courses and transporting players.
