Description

[Detailed explanation of the invention] [Industrial application field] This invention is used for entertainment facilities installed in amusement parks, etc.
This invention relates to an amusement ride facility that allows people to simultaneously enjoy the real thrills of a land vehicle such as a jet coaster and a pleasure boat traveling on a waterway.

[Prior Art] In an amusement park or the like, an amusement ride facility is constructed in which a track is formed by a waterway and a land route connected to the waterway, and vehicles (ships or vehicles) are run along the track of this closed route. Are known.

This vehicle travels around the waterway by riding on the water current of the waterway, so you can enjoy playing on a pleasure boat or boat, and by traveling on the land track, it is like a jet coaster etc. You can enjoy a variety of games such as traveling at a speed that allows you to fully enjoy the real thrill.

By the way, when a track is constructed of such a waterway and a land route following it, a means for pulling the vehicle from the waterway to the land route is required. This lifting means is
It is constructed by providing an uphill track that continues from the waterway to the land route, and installing a pulling mechanism to pull up the vehicle along this uphill track.

BACKGROUND ART Conventionally, in various amusement ride facilities installed in amusement parks and the like, various devices have been employed as means for pulling vehicles up to the highest part of the track.

For example, ``Patent Publication No. 176681/1989'' and ``Patent No. 14392/1989'' have already been proposed as devices for pulling a vehicle such as a jet coaster to the highest point of a track.

However, since the vehicle hoisting device described in the former publication is a rotary drive system using a pair of left and right hoisting tires, there is a risk of slipping due to the lubricating action of water for those that start hoisting from below the surface of the waterway. Therefore, it is not recommended to adopt it.

On the other hand, the lifting device described in the latter publication is of the type that uses a pulling chain to pull the vehicle to a high place, and in amusement ride facilities such as amusement parks, this type of lifting chain or wire lifting structure is most commonly used. has been done.

However, when using the above-mentioned lifting chain on an uphill track that extends from a waterway to an overland route, this lifting chain is submerged in water as it travels, so rust is likely to occur, and furthermore, a certain area is Since it is soaked in water, rust is particularly likely to occur in this area. Furthermore, even if lubricating oil such as oil is supplied to various locations, the lubricating oil will be submerged in water as the vehicle travels, and the lubricating oil will be washed away by the water, causing early wear. Furthermore, since the impact applied to the chain at the start of pulling is severe, this part of the chain is subject to severe wear, and there is a concern that its life will be shortened.

For this reason, if one pulling chain is stretched over the entire length of an uphill track from a waterway to an overland route, if you want to replace the chain early, you will have to replace the entire extremely long chain, which will reduce the cost of replacement. It becomes quite expensive.

For this reason, it is conceivable to use separate lifting chains for the part of the uphill track that is submerged in water and the part of the uphill track that is less likely to get wet with water at the upper position. In this way, if you want to replace the chain early due to early rust or wear due to immersion in water, you only need to replace the lower lifting chain, which reduces replacement costs and reduces maintenance and management costs. There are advantages such as being able to save money.

[Problem to be solved by the invention] However, when the pulling chain is configured separately into a lower part and an upper part, when the first pulling chain and the second pulling chain are connected in a straight line, these chains Since a sprocket is used to rotate the chain, at least in an area larger than the sum of the radii of the sprockets on which these chains are hung, which are used as relay points for the first and second pulling chains. Discontinuities occur. Therefore, when the vehicle that has been pulled up by the first lifting chain moves to the second lifting chain, the hooks protruding from the vehicle at the discontinuous portion do not engage, making it impossible to pull up the vehicle.

In order to prevent the occurrence of such a discontinuous portion, the upper end of the first pulling chain and the lower end of the second pulling chain are arranged in parallel to each other,
By providing hooks that engage with the first lifting chain and the second lifting chain, when the vehicle pulled up by the first lifting chain transfers to the second lifting chain,
While one hook is still engaged with the first lifting chain, the other hook is engaged with the second lifting chain so that these first and second lifting chains are able to move the vehicle in succession. It becomes possible to raise the

On the other hand, in such a chain-based pulling device, if the chain were to break, there is a concern that the vehicle would run backwards on the uphill track. To prevent this, this type of pulling device is provided with a reverse running prevention device.

Reverse run prevention devices that are commonly used are:
A rack is laid along the uphill track, and a hook is provided on the vehicle side that allows the vehicle to ride over the teeth of the rack one by one.When the vehicle attempts to run in the opposite direction, the hook engages with the teeth of the rack and the vehicle runs in the opposite direction. In other words, it is designed to prevent the aircraft from descending out of control.

However, if it is attempted to install a first pulling chain and a second pulling chain on the above-mentioned upward slope track, and also to install a rack for preventing reverse running on this upward slope track, the installation space occupied on this upward slope track becomes large. It is required to be quite large.

In addition, if an attempt is made to provide hooks on the vehicle side that engage with each of the first and second pulling chains, as well as other hooks that can be locked to the rack for preventing reverse running, the number of hooks will increase. The number of devices increases, the installation locations become complicated, and the configuration becomes complicated.

The present invention was developed based on these circumstances, and its purpose is to provide a vehicle lifting mechanism installed on tracks consisting of waterways and land routes.
To provide an amusement ride facility that has a simple configuration, can surely prevent reverse running, and is inexpensive to maintain.

[Means for Solving the Problems] In order to achieve the above object, this invention uses a track consisting of a waterway and a land route connected to the waterway, which constitutes a closed route as a whole, and a navigation system that rides on the water flow of the waterway. At the same time, in an amusement ride facility equipped with a vehicle that runs along a rail formed along the land route, and a pulling mechanism installed on a gradient track from the waterway to the land route and pulling up the vehicle, the vehicle pulling mechanism The first vehicle hoisting chain has one end submerged in the water of the waterway and the other end located halfway along the gradient track and located at a higher position than the water; a second vehicle hoisting chain running parallel to the other end of the vehicle hoisting chain, the other end of which is installed at the highest point of the gradient track, and running at the same speed as the first vehicle hoisting chain; and the second vehicle hoisting chain. a first anti-reverse rack provided on an extension line of the chain and parallel to the first vehicle pulling chain; and a first anti-reverse rack provided on an extension line of the first vehicle pulling chain and parallel to the second vehicle pulling chain. The second
a reversing prevention rack, which is rotatably provided on the vehicle and engages with the first vehicle lifting chain to pull up the vehicle, and an area through which the vehicle is pulled up by the second vehicle lifting chain. When the vehicle attempts to run in the opposite direction, the vehicle is pulled up by the first hook that locks onto the second reverse prevention rack and the first vehicle pulling chain that is rotatably provided on the vehicle. The vehicle is characterized by comprising a second hook that locks on the first reverse running prevention rack when attempting to do so, and a second hook that engages with the second vehicle pulling chain and pulls up the vehicle when the vehicle passes through this. .

[Operation] According to the present invention, when a vehicle traveling along a waterway reaches the bottom of an uphill track, the first hook provided on the vehicle engages with the first pulling chain, and the vehicle ascends the uphill track. start. In this case, the second hook provided on the vehicle is latchingly opposed to the first anti-reverse rack attached in parallel to the first lifting chain, so that in the unlikely event that the first vehicle pulling chain is Even if disconnected, these second hooks and first
The reverse running prevention rack prevents the vehicle from running in the wrong direction.

When the vehicle reaches the upper end of the first vehicle lifting chain, the first hook is still engaged with the first lifting chain and is facing the first anti-reverse rack. A second hook engages the lower end of the second vehicle lifting chain so that the vehicle is continuously raised without any discontinuities.

When the vehicle is further raised, the first hook that has been engaged with the first lifting chain faces a second anti-reverse rack installed in parallel with the second vehicle lifting chain so that it can be locked. Therefore, even if the second vehicle pulling chain breaks, the first hook and the second anti-reverse rack prevent the vehicle from running in the opposite direction.

In other words, in the present application, the first and second hooks each engage with the vehicle lifting chain to function to pull up the vehicle, and when they do not engage with the vehicle lifting chain, act as a reverse running prevention mechanism. Used for both lifting and reverse prevention.

Therefore, the number of hooks provided on the vehicle can be reduced.

In addition, for uphill tracks, a second anti-reverse rack is installed on the extension of the first lifting chain, and a second
Since the first anti-reverse rack is installed on an extension of the pulling chain, the lifting chain and the anti-reverse rack can be constructed from two lines, simplifying the construction.

[Embodiment] An embodiment of the present invention will be described below based on the drawings.

In the figure, 1 is a track, and this track 1 connects a land route 2 and a waterway 3 to form a closed route course as a whole.

The above-mentioned land route 2 is provided with a running course 4 at a high place that is rich in variation, curving up and down and left and right, and at the boundary with the above-mentioned waterway 3, an upward slope trajectory 5 heading from the waterway 3 toward the land route 2 is formed. With,
A downward slope trajectory 6 heading from the land route 2 to the waterway 3 is formed.

Then, from the above-mentioned uphill slope track 5 to the running course 4
A pair of rails 8, 8 are continuously laid across the downhill track 6. These rails 8,
8 has a U-shaped cross section, as shown in cross section in FIGS. 7 to 9, respectively.

The waterway 3 has a winding course, and a platform 7 is provided along the way. Passengers get on and off the vehicle 10 (ship = vehicle body) floating on the waterway 3 on the platform 7.

Water pumped up by a pump 11 is injected into one end (upper end) of the water channel 3, and this water flows toward the other end (lower end) of the water channel 3. The water flowing downstream is pumped up by the pump 11 provided at the lower end of the water channel 3, and the pumped water is again injected into the upper end of the water channel 3. Therefore, the water is circulated, and a flow of water is generated from the top to the bottom in the waterway 3, and the vehicle 10 floating on the water travels along the water flow from the top to the bottom.

The vehicle 10 has a boat structure on which a plurality of passengers can ride, and as shown in FIG.
4 and 25 are rotatably attached.

These wheels 23, 24, 25 are in rolling contact with the inside, upper surface, and inner surface of the rails 8, 8, respectively,
This guides the vehicle 10 along the trajectory of the land route 2.

Further, as shown in FIG. 6, a stay 26 is provided at the center of the bottom of the vehicle 10, and a first and second hook 31, 32 is rotatably attached.

These first and second hooks 31 and 32 are each formed with a stop surface 33 (only one shown), and these stop surfaces 33 abut on respective stoppers 34 (only one shown) formed on the stay 26. When these stop surfaces 33 come into contact with the stopper 34, the hooks 31 and 32 are restrained from rotating counterclockwise, as shown in FIG. 4. However, from this state, hook 31,
32 can be rotated clockwise.

The uphill track 5 is provided with a mechanism for pulling up the vehicle.

This vehicle pulling mechanism includes a first vehicle pulling chain 40 installed at the bottom of the uphill track 5 and a second vehicle pulling chain 41 installed at the top of the uphill track 5. The lifting chain 40 and the second vehicle lifting chain 41 are offset from each other to the left and right.

The first pulling chain 40 has one end submerged in the water of the waterway 3 and the other end located at a position higher than the water in the middle of the upward slope track 5, and both ends are wound around sprockets 42a and 42b. has been done. Note that 42c and 42d are auxiliary sprockets.

The second vehicle hoisting chain 41 has one end running parallel to the other end of the first vehicle hoisting chain 40 in the middle of the uphill track 5, and the other end is installed at the highest point of the uphill track 5. has been done. That is, the lower end of the second vehicle pulling chain 41 forms a portion parallel to the upper end of the first vehicle pulling chain 40, and overlaps in side view.

Both ends of the second vehicle pulling chain 41 are wound around sprockets 43a and 43b. One sprocket 43a is connected to a drive motor 45 and rotated by this drive motor 45. Therefore, the second vehicle pulling chain 41 travels in the direction of arrow A.

A transmission sprocket 46a is coaxially attached to the other sprocket 43b. Also,
Another transmission sprocket 46b is attached coaxially to the sprocket 42b wound around the other end of the first pulling chain 40, and a connecting chain 47 is connected between these transmission sprockets 46a and 46b.
is being passed over.

Therefore, the second vehicle pulling chain 4
The travel in the direction of the arrow A is transmitted to the first pulling chain 40 via the connecting chain 47, which in turn travels in the direction of the arrow B.

In other words, the first vehicle pulling chain 40 and the second vehicle pulling chain 41 are both driven to run at the same speed and in the same direction.

On the extension line of the second pulling chain 41, there is a first
A reverse running prevention rack 48 is installed. This first anti-reverse rack 48 is arranged parallel to the first vehicle lifting chain 40.

Further, a second anti-reverse rack 49 is installed on an extension of the first pulling chain 40.
This second anti-reverse rack 49 is arranged parallel to the second vehicle pulling chain 41.

The first and second hooks 31 and 32 attached to the vehicle 10 are connected to the first pulling chain 40, the second anti-reverse rack 49, the first anti-reverse rack 48, and the second anti-reverse rack. It is adapted to engage a rack 49, which will be explained later.

A vehicle introduction path 50 is formed downstream of the waterway 3 and above the uphill track 5.

The vehicle introduction section 50 is connected to the left and right side walls 51, 5 of the waterway 3.
1 and the rail 8 of the upward slope track 5 from inside the waterway 3,
A pair of guide rails 52, 52 are provided between the guide rails 52 and 8. A pair of guide rails 5
2 and 52 are made of L-shaped steel members with open upper surfaces, and are connected to the rails 8 and 8 at their upper ends.

Side rollers 53, 53 are rotatably attached to the lower left and right outer sides of the vehicle 10, and these side rollers 53, 53 are connected to the water channel 3.
The left and right side walls 51, 51 are in contact with each other. As a result, the left and right posture of the vehicle 10 is restricted and the upward slope trajectory 5
be guided by. As the vehicle 10 approaches the uphill track 5, the wheels 24, 24 ride on the guide rails 52, 52, and are pulled up as they are, so that the wheels 24, 24 enter the rails 8, 8. .

A water tank 60 is formed continuously on a downward slope track 6 heading from the land route 2 to the waterway 3.

In this water tank 60, the track forms a wavy slope 61, and the vehicle 10, which has descended by gravity on the downward slope track 6, jumps into the water surface of the water tank 60, and then jumps further into the aforementioned waterway 3. ing.

Here, the water tank 60 is provided isolated from the water channel 3, and has a basin 6 that is appropriately higher than the water surface of the water channel 3.
It is constructed by 2. Further, a pit 63 is formed in communication with the water channel 3, and this pit 63
is provided with another pump 64. This pump 64 pumps up water from the pit 63 and supplies water to the upper part of the downward slope track 6. This water flows down into the water tank 60 along the downward slope track 6, and the excess water in this water tank 60 overflows from the edge 62 of the water tank 60 and falls into the water channel 3.

The operation of the embodiment with such a configuration will be explained.

A vehicle 10 carrying passengers on the platform 7 travels along the water flow of the waterway 3 and reaches a vehicle introduction section 50.

In this vehicle introduction section 50, before entering the vehicle pulling mechanism, first, side rollers 53, 53 rotatably provided on the left and right sides of the vehicle 10 move against the side walls of the water channel 3, as shown in FIG. 51, 51 to regulate the left and right posture and position of the vehicle 10. When the vehicle 10 whose left and right positions have been regulated in this way advances further, the wheels 24, 24 protruding from the bottom of the vehicle 10 ride on the guide rails 52, 52,
In this state, the vehicle enters the vehicle lifting mechanism.

When the vehicle 10 enters a predetermined position in the vehicle introduction section 50, the vehicle 10 is detected by a position sensor (not shown) provided on the side wall 51, and a rotation command is given to the drive motor 45 using this detection signal.

Therefore, the motor 45 rotates, causing the second vehicle lifting chain 42 to run in the direction of arrow A, and this running is transmitted to the first lifting chain 40 via the connecting chain 47, which also It runs in the direction of arrow B.

That is, the single motor 45 causes the second vehicle pulling chain 42 and the first vehicle pulling chain 40 to travel simultaneously in the same direction and at the same speed.

When the vehicle 10 advances to the pulling start position, as shown in FIG. 31 in the counterclockwise direction in FIG. 1st hook 3
1, the stop surface 33 comes into contact with the stopper 34 of the stay 26, thus preventing rotation in the counterclockwise direction, so that the pin 40 of the first vehicle pulling chain 40
Lock in a. Therefore, the vehicle 10 is hooked to the first vehicle lifting chain 40 and begins to ascend the uphill track 5.

At this time, the second hook 32 is connected to the first hook 32 installed in parallel to the first vehicle pulling chain 40.
It repeats the wave-like movement while sliding on the upper surface of each tooth of the anti-reverse rack 48, overcoming these teeth one by one.

In this way, the vehicle 10 starts to be pulled up by the pulling mechanism, and when it reaches a predetermined position, the wheels 24, 24 protruding from the lower part of the vehicle 10 move to the guide rails 52, 52.
Then, as shown in FIG. 7, the vehicle changes to the rails 8, 8, and thereafter travels along the rails 8, 8 on the land route 2.

While the vehicle 10 is ascending on the uphill track 5 as the first vehicle pulling chain 40 travels, in the unlikely event that the first vehicle
When an unexpected situation occurs such as the vehicle pulling chain 40 breaking and the vehicle 10 attempts to run in the opposite direction, the second hook 32 hits the teeth 48a of the first reverse running prevention rack 48, causing the second The hook 32 is
The stop surface 33 abuts against the stopper 34 of the stay 26, thereby preventing rotation in the counterclockwise direction, so that it is engaged with the teeth 48a of the anti-reverse rack 48. This prevents the vehicle 10 from running backwards on the slope.

In this way, when the vehicle 10 reaches the top of the first vehicle lifting chain 40, the said second vehicle lifting chain 40 and the second vehicle lifting chain 41 overlap, 32 from the first anti-reverse rack 48 to the second
The vehicle pull-up chain 41 is then engaged with the pin 41a.

This situation is shown in Figure 8, where:
The first hook 31 is still engaged with the pin 40a of the first vehicle lifting chain 40 and thus also the first hook 31 and the second hook 32 are connected to the first vehicle lifting chain 40 and the second vehicle lifting chain 40, respectively.
The vehicle 10 is being pulled up by engaging the vehicle pulling chain 41 of the vehicle.

Further, when the vehicle 10 is pulled up, the first hook 31 separates from the first vehicle lifting chain 40 and faces the second anti-reverse rack 49, as shown in FIG. That is, the vehicle 10 continues to be pulled up because the second hook 32 is engaged with the second vehicle lifting chain 41, and in this case, the first hook 31 is engaged with the second vehicle lifting chain 41, as shown in FIG. Reverse running is prevented by opposing the second reverse running prevention rack 49.

After following this process, the vehicle 10 moves to trajectory 1.
The vehicle is pulled up to the highest point of the land route 2, and then descends on a traveling course 4 by gravity, traveling on undulations and making U-shaped turns, until it reaches a downward slope track 6.

The vehicle 10 further accelerates and descends on the downward slope trajectory 6, jumps once into the water surface at the water tank 60, jumps at the wavy slope 61, and jumps into the waterway 3.

In this way, the vehicle 10 returned from the land route 2 to the waterway 3.
is returned to the platform 7 by the flowing water of the water channel 3.

In such a configuration, the vehicle lifting chain installed on the uphill track 5 is replaced by a lower first vehicle lifting chain 40 that is partially submerged in water;
Since the chain is divided into the upper second vehicle pulling chain 41, chains that are prone to rust and wear are concentrated in the lower first vehicle pulling chain 40. Only the vehicle pulling chain 40 needs to be replaced.

Therefore, there is no need to replace one long pulling chain, and the replacement cost is reduced.

Moreover, the first vehicle pulling chain 40 at the bottom
and the upper second vehicle pulling chain 41 are arranged parallel to each other at these divided portions, that is, they overlap in side view, and the vehicle 10 is provided with hooks that can engage with these pulling chains 40 and 41, respectively. Since hooks 31 and 32 are provided, there are times when both hooks 31 and 32 are engaged with the pulling chains 40 and 41, respectively, at the relay point between the chains, and there is no discontinuous part.
The vehicle 10 can be pulled up smoothly.

Further, a first anti-reverse rack 48 is installed parallel to the first vehicle pulling chain 40 and on an extension of the second vehicle lifting chain 41, and
A second anti-reverse rack 49 is installed in parallel with the second vehicle lifting chain 41 and on an extension of the first vehicle lifting chain 40, and the first and second hooks 31 and 32 are connected to the anti-reverse rack 49. Since it also serves as a claw, the number of parts is reduced and the structure becomes simpler.

In addition, on the upward slope track 5, a second anti-reverse rack 49 is laid on an extension of the first pulling chain 40, and a first anti-reverse rack 48 is laid on an extension of the second pulling chain 41. Therefore, these can be configured with two lines, which simplifies the configuration.

[Effects of the invention] As explained above, according to the invention, in a vehicle lifting mechanism installed on a track consisting of a waterway and a land route, the vehicle pulling chain is divided into a first lifting chain submerged in water and a second lifting chain located at the upper part. So,
Chains that are prone to rust and wear are concentrated in the lower first pulling chain, and therefore only the lower pulling chain needs to be replaced, resulting in lower replacement costs. In addition, the first pulling chain at the lower part and the second pulling chain at the upper part are arranged parallel to each other at the divided portion, and the first and second pulling chains at the vehicle side are respectively engageable with both of these pulling chains. Since the second hook is provided, both hooks simultaneously engage the respective lifting chains at the relay point between the chains, eliminating the occurrence of discontinuous portions and allowing the vehicle to be pulled up smoothly. Further, a first anti-reverse rack is installed parallel to the first pulling chain and on an extension of the second pulling chain, and a first anti-reverse rack is laid parallel to the second pulling chain and on an extension of the first pulling chain. Lay the second anti-reverse rack, and
Also, since the second hook is also used as a claw for preventing reverse running, the number of parts is reduced and the structure is simplified.
