Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport device that automatically transports articles on a predetermined course, and in which a transport vehicle loaded with products and parts for assembly line work in a factory or the like is moved along a work course. In particular, the present invention is particularly effective at golf courses, where a transport vehicle loaded with golf bags and equipment is automatically transported while playing the golf course. It is characterized by:

Conventionally, methods for transporting equipment at golf courses without inputting input have been using electric vehicles, monorails, lifts, or Green Boy (trade name), but the former electric In the case of an automobile type, a paved walkway or rail was used instead of damaging the green. The latter type also required the construction of rails, supports, etc. high above the ground.

These installations not only significantly spoil the scenery of the golf course, but also cause balls to fall onto them and cause them to band irregularly, reducing the interest in playing.Furthermore, electric vehicles and other vehicles are forced to drive onto the grass (whether rough or fairway). If it had to be passed through, its own weight alone was over 85 kg, which not only had the fatal disadvantage of seriously damaging the lawn, but also had the disadvantage of requiring enormous construction and maintenance costs.

A well-known method in which a rope is buried underground and the rope runs, and a grip is provided on the vehicle and the grip is engaged with and disengaged from the rope to move and stop the vehicle is the San Francisco road vehicle. Are known.

However, the terrain on which the rope can be buried so that it can run freely can be flat ground (it doesn't matter whether it is sloped or not), convex land in the shape of a mountain, or concave land such as a depression or a part that transitions from flat land to convex land. The rope must be strung and supported by pulleys in accordance with the above-mentioned flat or convex surfaces, and this can be solved by supporting the rope from the bottom surface, and at curve points, the rope must be supported by a number of pulleys that touch the sides of the rope. A desired curve can be easily obtained with the pulley. However, on the concave ground, unless a pulley is used that touches the top of the rope, the rope will fly up from underground. However, in the cable car described above, since the grips engage with the upper surface of the rope, the pushing pulley (a pulley for pushing the rope downward from the upper surface of the rope) in contact with the upper surface of the rope prevents the grip from passing through. Therefore, in a concave area where the pressing pulley is in contact with the top of the rope to prevent the vehicle from flying up, the grip is removed from the rope, the vehicle is pushed by inertia or input to pass through the concave area, and the grip is removed from the rope again. The vehicle is driven by engaging with the engine. For this reason, in the case of complex terrain with many unevenness, input operations such as stopping, pulling up the grip, and re-biting must be performed frequently, making it difficult to operate. There was no more practicality than just the case.

One of the objects of the present invention is that a rope running endlessly by a motor inside a U-shaped trench buried at the same level as the ground surface can be supported only on the side surface of the rope or, if necessary, on the bottom surface of the rope, so that it can be used on any of the various terrains mentioned above. It is also applied to only a few special parts, for example, in the part where the ropes cross, a push pulley that touches the top of the rope is used, and only in this part it is necessary to disconnect the rope from the chassis. However, it is characterized by the fact that the push pulley in contact with the upper surface of the rope is not used at all on any other concave terrain with severe concave or convex slopes, and therefore the rope runs smoothly without disconnecting from the chassis. It is something to do.

Another objective is that a U-shaped groove body buried along the ground surface is provided with rope pulleys that are in contact with the sides of the rope arranged in a wave shape (S-shape) that alternately contact the sides of the rope. The purpose of the present invention is to divide and hold the repulsive force that causes the rope to move outward from the rope pulley due to the tension applied to the rope.

Another objective is that artificial turf or a rubber plate is provided on the upper surface of the U-shaped groove so that it is difficult to distinguish from the surrounding grass at first glance, so that it does not spoil the scenery of a golf course or the like. Furthermore, the U-shaped groove body has a relatively narrow width (for example, about 100 mm) and an opening (about 30 to 40 mm) that is large enough to prevent the golf ball from falling into it, and the inner surface and side walls of the flange inside the U-shaped groove body are narrow. The transport vehicle has a guide device attached to its inner surface that also serves to prevent it from tipping over, making it safe for the transport vehicle to move on its own.

Another objective is to provide a main wheel approximately below the center of the total load of the lightest hand-carried cart (hereinafter referred to as a cart) that carries a golf bag, etc. By running in contact with the surface of the artificial turf on the U-shaped groove body, most of the load is borne on this artificial turf, which is easy to reposition, and the remaining small amount of the load is borne. The stability of the cart operation is obtained by having auxiliary wheels that touch the lawn as much as possible. In this way, almost all of the load is borne on the stable U-shaped groove on the road surface,
The training wheels are designed to only come into contact with the grass when the balance is lost, so there is very little damage to the grass, so the Kyaday Kart can run anywhere on the entire course, including the fairways, which has never been done before. is made possible. In other words, the upper surface of the narrow U-shaped groove (for example, 10 cm, and the pavement width of the above-mentioned expressway is about 150 cm) is covered with artificial turf, so that it can be visually indistinguishable from the lawn of the fairway, making it ideal not only for scenery but also for games. The ball does not lose interest in the road, and even if the ball falls on it, the bounce is almost the same as on grass, and it is better than a conventional paved road (150 cm wide).
Its characteristics are completely different from those of concrete roads (concrete roads). Moreover, by having the cart run over the most favorable position, such as the fairway or rough, the distance between the golf bag and the ball's landing position becomes extremely short, resulting in an increase in the number of players and labor savings for the player due to faster play. This will improve service and make it easier to fill in holes, which will bring great benefits to management.

In this way, the present invention combines straight, corrugated, or curved block-shaped U-shaped grooves mass-produced at factories in accordance with golf courses, connects them, and buries them along the ground surface. However, for example, a 90° bend can be divided into several blocks and mass-produced, simplifying the construction work and saving costs. A rotatable rope pulley is provided in each of these U-shaped grooves, and the rope is made to run endlessly in the order of its course by not touching the top surface of the rope at all, but only touching the side or bottom surface of the rope. A kyaday cart with a freely adjustable grip consists of a main wheel that runs on the U-shaped groove and an auxiliary wheel that runs on the lawn. To safely propel a cart by itself without causing mechanical damage or noise due to contact of a grip with a guide device from which it is impossible to escape outside the place and a rope pulley supported in contact with the side of the rope.

Next, as an example, a case of a kayak cart at a golf course shown in the drawings will be described.

In Figure 1, a golf course is normally divided into nine out holes and nine in holes, and after leaving the clubhouse and playing the nine out or in holes, the golf course returns to its original clubhouse. It is designed to. In other words, the clubhouse is the base of play.

Therefore, from the clubhouse H of this base, a straight U-shaped groove S, a wavy U-shaped groove W, or a curved U-shaped groove C
It consists of three types of block-shaped U-shaped grooves, which are selected according to the topography and are connected almost uniformly to the ground surface, and the fairway from the teeing ground of the first hole.
A ₁ and the rough part along and in contact with fairway A ₁ as shown by the dotted line in the first figure, or the fairway A ₁ is sequentially extended to the tee ground, fairway A ₂ and further as shown by the dashed line in the same figure. ,A ₃ ,,A ₄ ,,A ₅ ,,A ₆ ,,A ₇ ,
, A ₈ and further A ₉ to be connected to the original location of clubhouse H.

The rope R is stretched so that it is supported by rope pulleys provided in each of the U-shaped grooves and run endlessly by the motor M in the order of courses numbered 1 to 9.

Next, each of the U-shaped groove bodies will be explained.

Each of the U-shaped groove bodies, that is, the straight U-shaped groove body S, the wave-shaped U-shaped groove body W, and the curved U-shaped groove body C, each has a mounting seat 10 to the foundation (which is necessary for the straight U-shaped groove body S). (not necessarily required) and smaller than the diameter of a golf ball, e.g. 30
A flange portion 1 with a relatively narrow width, for example, about 10 cm, having opening stripes 11, 11a, 11b of about 40 mm.
2 and 12, and grooves 13, 13a and 13b, respectively, and the straight U-shaped groove body S can support the hanging of the rope R due to its own weight as necessary, as shown in FIG. The shaft 15 of the support roller 14
A shaft hole 16 may be provided to support the.

As is clear from FIGS. 3 and 4, the wavy U-shaped groove body W has the opening strip 11 and the groove portion 13 formed in a wave shape as an opening strip 11a and a groove portion 13a,
Furthermore, as is clear from FIG. 4, the rope pulley 17,
As shown by 17a and 17b, the rope pulleys 17 to 17b are arranged in a zigzag manner through the groove 13a so that the planes of the rope pulleys 17 to 17b are horizontally located and rotatable, and contact both sides of the rope R alternately. Therefore, the rope R runs in a wave shape, and is constructed in the form of a block of, for example, three rope pulleys, such as the plurality of rope pulleys 17 to 17b.
Further, the curved U-shaped groove body C has an opening strip 11b and a groove portion 13.
b is curved and a plurality of rope pulleys 1
The rope pulleys 8, 18a, 18b, and 18c are arranged in a block shape such that the rope pulleys 8, 18a, 18b, and 18c are arranged in contact with only one side of the rope R and have a predetermined curve so that the planes of the rope pulleys 18 to 18c are located in the horizontal direction and are rotatable. be. Furthermore, each of the U-shaped grooves, especially the straight U-shaped groove S, has an enlarged opening 11' formed by partially removing the flanges 12, 12, and is disposed at a required position. Furthermore, the wavy U-shaped groove body W and the curved U-shaped groove body C are provided with rope pulleys 17 to 17b as described above.
and 18 to 18c are provided, so the width of that portion increases and does not match the width of the straight U-shaped groove body S. Therefore, the wide part is the surface 10' which is lowered one step.
It is preferable to bury it underground as it improves the appearance because all the courses extend with the same width.
Examples of how these U-shaped groove bodies S, W, and C are used will be explained based on FIGS. 8 and 9.

Rope R in a straight line on flat ground F with no unevenness on the ground
When operating, the straight U-shaped groove bodies S are connected linearly, and if necessary, the support roller 14 is installed in the appropriate position using the shaft hole 16, and the inner wall of the groove part 13 due to the hanging of the rope R. Prevents rubbing against the surface. In addition, when curved in the horizontal direction on this flat ground F, the curved U-shaped groove bodies C are connected, and the desired curve can be obtained by the number of connections. This is easily solved by the rope pulleys 18-18c that are in contact with only the ropes. However, when the rope R passes through the concave ground B as shown in Figure 9,
It is a natural physical phenomenon that the rope R flies up as shown by the dotted chain line due to its tension. Conventionally, in such a case, the rope R' was pushed down like the rope R by a pressing pulley (not shown) that contacts the upper surface of the rope and pushes it down to the position shown by the rope R.

In the present invention, a wavy U-shaped groove body W is used without using any pressing pulley that comes into contact with the upper surface of the rope, that is, a rope pulley that makes the rope R wave-shaped by arranging the wavy U-shaped groove bodies W in a zigzag shape. 17
By connecting and laying the surfaces of ~17b almost parallel to the ground surface of the concave ground B, the rope R where the curve of the concave ground B becomes a straight line under tension between each rope pulley.
A curve is formed by a series of relatively short straight lines. In short, by forming a curved surface into a set of many short straight lines, the lifting force caused by the tension of the rope R is shared by many rope pulleys and eliminated. Therefore, since there are no obstructions such as push pulleys on the upper surface of the rope R, the grip descending from the upper transport vehicle can pass through the concave ground B without any hindrance while keeping the rope engaged. . In the case of a relatively steep concave ground, the corrugated U-shaped groove body W may be connected at a slight angle, or the concave ground B may be moved diagonally by combining it with the curved U-shaped groove body C. It is possible to lay it (in other words, it is the same as a gently concave surface), or it is also possible to lay it in a meandering manner.

Next, the grooves 13, 13a and 13b of the U-shaped grooves S, W, and C are laid in contact with the support roller 14, the rope pulleys 17 to 17b, and the rope pulleys 18 to 18c to form an endless shape. A wheel cart having a grip that engages and disengages from a rope R stretched over the ground will be described.

Conventional push carts have the lightest weight (approximately 25 kg for 4 bags) and cause less damage to the lawn, and have been widely used for a long time, but they have the disadvantage of requiring a large labor burden on the carts. Therefore, electric carts using batteries, etc. are used instead, but these carts weigh about 85 kg alone, and in addition, the friction force caused by self-propelled batteries causes significant damage to the lawn. A dedicated paved walkway is being constructed away from the rough terrain. However, this is far away from the fairway and rough where most of the balls fall, which reduces the service of the golf course and makes playing time longer.In addition, it not only costs money but also spoils the scenery of the golf course, and the ball during play. If the ball fell on top of this, it would bounce irregularly and seriously diminish the interest of the play.

The weight of the cart according to the present invention is almost the same as that of a manual cart (approximately 25 kg), and the center of gravity of the total load is approximately located so that 70 to 80% of the total load is borne by the main wheels rolling on the U-shaped groove. A main wheel is provided at the bottom, and multiple auxiliary wheels are provided simply to prevent the cart from tipping over, and these auxiliary wheels bear 20 to 30% of the remaining load, and these auxiliary wheels only touch the ground when the cart loses its balance. This causes very little damage to the grass that comes into contact with the training wheels. An example of this will be explained with reference to FIGS. 10 and 11. The cart CA includes boxes 20, 20a, 20b, on which a golf bag BA can be mounted and fixed on a frame-shaped chassis 19 that is approximately cross-shaped when viewed from above.
20c in a cross shape, the center of gravity of the total load O
is located approximately at the center of the chassis 19.

A main wheel 21 is formed directly below this center of gravity position O, and auxiliary wheels 22, 22' are formed on the left and right sides of the main wheel 21, and these auxiliary wheels 22, 22' are designed so that they do not touch the ground when the main wheel 21 touches the ground to maintain balance. If it is coaxial with the main wheel 21, use a slightly smaller diameter wheel, or use an auxiliary wheel 22,
The shaft of 22' is configured to be slightly above the shaft of the main wheel. Furthermore, there are U on the front and back of the main wheel 21, just like the main wheel.
Auxiliary wheels 21a in contact with the surfaces of the groove bodies S, W, and C;
21b is provided. In addition, a guide device T is provided only before and after or in front of the main wheel 21, if necessary, T′ and at least one
Grips G are provided on the chassis 19, respectively.

The guide device T, as shown in an embodiment in FIG.
The cart CA has a contact portion 25 that is guided toward and away from the inner longitudinal surface of the groove, and that comes into contact with the inner lower surface of the flange portion 12 of the U-shaped groove body when the cart CA loses its balance and tilts. The lever guiding device T is attached to a gripping device G' having a grip G, and the gripping device G' is supported by a ring-shaped holder 34 so as to be able to rotate to some extent, and the holder 34 is pivoted about a pivot 33. The flange-less portion of the U-shaped groove can be moved out and retracted from the U-shaped groove manually or by an automatic device using a known remote control. In addition, 32 is an angle type leading piece, and the above-mentioned artificial turf 12', 1
2' or a rubber plate. The other guide device T' has the same rotating body 24, contact portion 25, etc., and may be rotated by the aforementioned pivot 33, but may be of the type that slides linearly up and down and retracts from the U-shaped groove. It can be anything. Reference numeral 36 designates a knock pin that protrudes from the holding body 34 and secures the grip device G' and the like.

Further, as shown in FIGS. 12 and 13 as an embodiment of the grip G and the grip device G', the engagement pieces 26, 26' of the rope R are controlled by the vertical movement of the lifting shaft 27 via the tongue-type linkage L. As a result, grip G and rope R are brought into engagement and disengagement.
That is, the lifting shaft 27 is connected to a nut pipe 27' which cannot be rotated, and the nut pipe 27' is threadedly engaged with a threaded rod 28. The threaded rod 28 is rotated by the rotation of the motor 29, and the lifting shaft 27 is connected to the threaded pipe 27'. It opens and closes the occlusal pieces 26, 26' by moving up and down linearly together with 27'. Next, the operation of the above embodiment will be explained.

In the clubhouse H section, the cart CA is positioned over the enlarged opening 11' without flanges 12, 12 of the straight U-shaped groove S as explained in FIG. 6, and the guide devices T and T' are manually or electrically operated. At the same time, the grip device G' is rotated about the pivot 33 or lowered to enter the straight U-shaped groove body S. The rope R is then positioned between the bite pieces 26, 26'. At this time or in advance, the golf bag BA is mounted in the boxes 20 to 20c and fixed with a band or the like. At that time, the main shaft 21 is a straight U-shaped groove body S.
The motor 29
The screw rod 28 rotates when the lever is started, lowering the lifting shaft 27, and is stopped when the limit switch 30 is activated, and the engaging pieces 26, 26' rotate around the pins 31, 31' to strongly bite the rope R. Therefore, the cart CA moves at the running speed of the rope R (generally speaking, the walking speed of most people is slightly faster than that).

When you go outdoors such as on a golf course, the groove part 13~
Artificial turf 12', 12' made of flexible material such as colored rubber plates divided on the opening strip 11 is attached to prevent rainwater, stones, soil, sand, etc. from entering 13b, so this is separated. The cart CA moves forward while being pushed by the metal fittings 32. In the golf course area, the terrain is complex and the cart CA also tilts from side to side, but this slope is supported by either of the auxiliary wheels 22, 22' touching the ground, and the guide device T or the guide device inside the U-shaped groove. Since the abutting portion 25 of T' abuts on either of the inner surfaces of the flanges 12, 12 and does not escape from the U-shaped groove, the cart CA is safely supported without greatly tilting, and the rotating body 24 is U-shaped. The grip G is guided in contact with the inner wall of the groove portion 13 of the groove body, and the rotating body 24 as well as the grip G is held at approximately a predetermined position, and the rope pulleys 17 to 17a or 1
8 to 18c, or even the support roller 14, etc., and no noise is generated.

In this way, the cart CA moves by itself and passes through fairways _A1 to _A9 as the play progresses. In addition, the cart CA is temporarily stopped at the playing ground or the point where the ball falls, but at that time, the motor 2
By opening the bite pieces 26, 26' in step 9, the cart CA can be easily stopped temporarily, and by opening the U-shaped groove of the enlarged opening 11' at an appropriate point. Even if the guide devices T, T' and grip device G' are installed in the U-shaped groove body, remove the dowel pin 36, rotate around the pivot 33, and take out the grip G and other parts as described above. often,
In this case, you can also manually push the cart CA. Furthermore, depending on the course, the ropes R may intersect; for example, the intersection point P (first
(shown), since the ropes R are located above and below and intersect, a U-shaped groove body having an enlarged opening 11' is provided just before and after the intersection point P for the rope passing below.
This can be done by temporarily taking out the guide devices T, T' and grip device G' from the U-shaped groove, pushing them through the intersection point P by hand, and then setting them back into the U-shaped groove.

Furthermore, since each U-shaped trench is buried in the ground,
Artificial turf 12', 12' can be used to prevent this, but it is possible that dirt, dry grass, etc. may enter and make it difficult for the guide device or grip to travel.In that case, for example, connect a suction-type vacuum cleaner to rope R. Cleaning can be done easily by moving around the course with the suction port facing inside the U-shaped groove.

As mentioned above, there is a slope in the course, so cart CA
However, the guide devices T, T' and the grip G are fixed by the contact portion 25.
The rotating body 24 rotates lightly without coming out of the grooves 13, 13a, and 13b of the groove body, and the rotating body 24 rotates smoothly even when shaken during traveling. Therefore, the auxiliary wheel 21a prevents the vehicle from falling forward, and the auxiliary wheel 21b prevents the vehicle from falling backward.
Most of the load is borne by 21a and 21b,
Since these run on the artificial turf 12' on the U-shaped groove, they can be easily replaced even if they wear out, and will not damage the natural turf.
2 and 22' are not in contact with the ground at all times, and only touch the ground a little when the cart is sloped, so there is less wear and tear on the grass than if the cart is in constant contact with the ground, and it also greatly contributes to the stability of the cart when running by hand. It is. In addition, if the cart runs in the center of the fairway, it can improve the service of the Kiyaday, repair dents (hit ball marks) with soil, etc., and shorten playing time, making it possible to play without using the Kiyaday. , the atmosphere of the golf course is that the construction is underground, and the surface width is narrow, about 10 cm.
(The width of the paved road for conventional golf carts is
(approx. 150 cm), we use artificial grass and rubber boards that have the same color as natural grass, so they are not noticeable and do not feel strange at all.
