Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a game vehicle facility provided in an amusement park or the like and provided with a track for lifting a game vehicle along a slope track.

(Prior art) In amusement vehicle facilities installed in amusement parks, etc., as seen on various coasters, etc., pull the amusement vehicle from a low place to a high place and use gravity to drop this vehicle to a low place. It is known to play, slide, or play.

This is simply for earning the potential energy of the game vehicle at the stage of raising the game vehicle from a low place to a high place, and at this time, the thrill is rarely enjoyed.

Therefore, if a large space is taken up in such a pulling track, there is a problem that the installation space of the entire coaster becomes large.Therefore, there is a demand to construct this pulling track in a small space. Tend to steeper the gradient.

On the other hand, as a means for pulling a game vehicle on such a gradient orbit, a chain is often used as described in Japanese Utility Model Laid-Open No. 61-200095.

However, the pulling device using the chain requires a rail for guiding the amusement vehicle, a pulling mechanism by the chain and a hook mechanism for engaging and disengaging the chain, and the entire structure becomes complicated.

It is conceivable to use a conveyor belt device instead of such a chain type pulling device. The conveyor belt device is composed of a conveyor belt that spans between a driving pulley and a driven pulley, and a large number of rotatable rollers that support the belt and that are arranged at intervals between the driving pulley and the driven pulley. A game vehicle is placed on the conveyor belt, and the game vehicle is pulled up to a high place as the conveyor belt travels.

(Problems to be Solved by the Invention) However, in the case of a pulling device using a conveyor belt device, the following problems may occur.

That is, if the game vehicle is long, at the stage where this game vehicle, which has advanced substantially horizontally, starts to be placed on the lower end of the conveyor belt inclined at a predetermined angle, the leading end of the vehicle is started to be pulled up by the conveyor belt. However, at this time, since the rear end part is not yet on the conveyor belt, the vehicle is supported by the front end part and the rear end part, and the central part is in a floating state.
In this case, a large stress is generated in the central portion of the vehicle, and the friction between the tip portion of the vehicle and the conveyor belt is small, so that the vehicle and the conveyor belt may slip and the vehicle may not be smoothly placed on the conveyor belt.

Also, in the area where the amusement vehicle reaches the top of the conveyor belt and bends so that the inclination of the conveyor belt changes horizontally at this top, only the center of the vehicle is supported by the conveyor belt, and the front and rear ends of the vehicle are supported. Becomes floating in the air,
Also in this case, stress is generated in the central portion.

Therefore, the longer the play vehicle is, the larger the stress generated in the central portion is, the higher the strength is required, and the smaller the friction at the start of riding is that the ride belt cannot be reliably rided on.

The present invention has been made based on the above circumstances, and it is an object of the present invention to provide a game vehicle facility that can reliably pull up the game vehicle without causing a large stress to the game vehicle.

(Means for Solving the Problem) The first aspect of the present invention is to provide a conveyor belt device along a gradient track, and this conveyor belt device hangs a conveyor belt between a drive pulley and a driven pulley and Comprised of a large number of freely rotatable rollers that support the belt and are arranged with a gap between the driven pulleys,
In an amusement vehicle facility in which an amusement vehicle is placed on this conveyor belt device and carried to a high place, the roller installed in the area where the gradient of the above-mentioned gradient track changes is constituted by a swingable roller that can swing up and down. Is characterized by.

According to the second aspect of the present invention, the gradient track is formed by a first conveyor belt device having one end on a gentle slope and the other end connected to the first conveyor belt device.
Second steeper than the conveyor belt device
It is characterized in that the oscillating rollers are arranged at the connecting ends of the first conveyor belt device and the second conveyor belt device.

(Operation) According to the present invention, since the rocking roller installed in the area where the gradient of the gradient track changes, the rocking roller sinks when the amusement vehicle is placed on it, so that the contact area between the amusement vehicle and the conveyor belt becomes large, and the sliding roller slides between them. And the large stress is not generated in the center of the vehicle.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

FIG. 1 is a plan view showing the entire play track, where 1 is a waterway, 2 is an ascending course of a land route, and 3 is a descending course of a land route.

Further, traveling wheels 7 ... And side guide wheels 8 ... Are attached to the four corners of the vehicle 5, and these traveling wheels 7 ... And side guide wheels 8 ... Run down the traveling course 3 of the track. In this case, the vehicle 5 should be self-propelled.
Therefore, the descending course 3 has a rail which is inclined downward and guides the vehicle 5 so as to be self-propelled, but the illustration is omitted.

The ascending track 2 is provided with a pulling device extending from the water channel 1, which will be described with reference to FIG.

In the figure, 10 is a first conveyor belt device, and 20 is a second conveyor belt device.
Is a conveyor belt device.

These first and second conveyor belt devices 10 and 20
Each of these is constituted by driving rubber conveyor belts 13 and 23 between drive pulleys 11 and 21 and driven pulleys 12 and 22, respectively.

The drive pulley 21 of the second conveyor belt device 20 is adapted to be rotationally driven by the drive motor 30, so that the belt 23 of the second conveyor belt device 20 is directly raised by the drive motor 30. In addition, 31 indicates a tension pulley.

The driven pulley 22 of the second conveyor belt device 20 and the drive pulley 11 of the first conveyor belt device 10 have a chain.
Therefore, the first conveyor belt device 10 is driven by the second conveyor belt device 20 and travels at the same speed.

Each of these conveyor belt devices 10 and 20 is provided with rollers between drive pulleys 11 and 21 and driven pulleys 12 and 22, respectively, and the conveyor belts 13 and 23 are run on these rollers. These rollers will be described later.

The lower end side of the first conveyor belt device 10 is provided so as to be submerged in the water channel 1 so that the front end of the vehicle 5 traveling in the water channel 1 can ride up. The slope of the first conveyor belt device 10 is formed to be relatively small so that the front end of the vehicle 5 can be easily climbed up.

The lower end of the second conveyor belt device 20 is close to and close to the upper end of the first conveyor belt device 10,
The inclination gradient of the second conveyor belt device 20 is the first
It is set to be steeper than the gradient of the conveyor belt device 10.

The upper end of the second conveyor belt device 20 forms a curved portion 35 that changes horizontally as it goes upward so as to be continuous with the upper end of the descending track 3.

By the way, the region of the upper end portion 36 of the first conveyor belt device 10 and the region of the lower end portion 37 of the second conveyor belt device 20 installed adjacent to the upper end portion 36 have different gradient angles, The curved portion 35 at the upper end of the second conveyor belt device 20 is a region where the gradient of the gradient track changes.

In the areas 36, 37 and 35 where the gradients change, swing rollers 15, ..., 25 ... Which can swing up and down are arranged as rollers for supporting the conveyor belts 13, 23.

Structures of these rocking rollers 15 ..., 25 ... are shown in FIGS.
It will be described with reference to the drawings.

A bracket 40 (only one of which is shown) is attached to the left and right side frames 33, and a support shaft 41 is stretched between the left and right brackets 40. This support shaft 41
A swing lever 42 is swingably attached to the swing lever 42, and a swing shaft 45 is provided at one end of the swing lever 42. The swing rollers 15, 25 are rotated on the swing shaft 45 via a bearing (not shown). It is supported freely. A coil spring 43 is stretched between the other end of the swing lever 42 and the side frame 33. Therefore, the swing lever 42 rotates counterclockwise about the support shaft 41 in FIG. It is energized. As a result, the rocking rollers 15, ..., 25 are also urged counterclockwise about the support shaft 41 to push the conveyor belts 13, 23 upward.

Then, when a pressing force of a predetermined value or more is applied to the conveyor belts 13 and 23, the swing rollers 15, 25 are rotated clockwise about the support shaft 41 against the force of the coil spring 43, The lower surface 42a of the rocking lever 42 can be rotated until it comes into contact with the stopper 44.

In the first conveyor belt device 10, all the rollers are composed of the oscillating rollers 15 ..., and the second conveyor belt device 20 has oscillating rollers at the lower end portion 37 and the curved portion 35 at the upper end portion. 25 ... is provided.

A large number of fixed rollers 26 are provided at intervals in the inclined intermediate portion between the lower end portion 37 and the upper end curved portion 35 of the second conveyor belt device 20.

Although not shown in detail, these fixed rollers 26 ... Side frame 33
It is rotatably supported on the shaft 27 and is rotatably attached to the pivot 27 via a bearing 28, as shown in FIG.

Each fixed roller 26 is formed with a V groove 29, and the conveyor belt 23 is formed with a V belt portion 24 into which the V groove 29 is fitted. The roller 26 is prevented from meandering by fitting in the V groove 29 of the roller 26.

In addition, the fixed rollers 26 ...
A V-shaped groove 29 similar to the above is formed to prevent the belts 13 and 23 from meandering running.

The operation of the embodiment having such a configuration will be described.

The amusement vehicle 5 running down the descending course 3 reaches the waterway 1 and runs along the waterway 1. Then, when the vehicle 5 reaches the lower end of the ascending course 2 around the water channel 1, the bottom surface of the tip end of the vehicle 5 rides on the first conveyor belt device 10.

Since the belt 13 of the first conveyor belt device 10 is supported over the entire length by the rocking rollers 15, ... When the tip of the game vehicle 5 rides up, the rocking rollers 15 ... Therefore, since the belt 13 can be flexed, the impact when riding can be mitigated.

This prevents the belt 13 from being damaged.

Moreover, the belt 13 is bent by the rocking rollers 15 ... Sinking, and the area where the tip of the vehicle 5 contacts the belt 13 increases. Therefore, in combination with the fact that the inclination angle of the first conveyor belt device 10 is small, the area on which the vehicle 5 rides on the belt 13 is large, that is, the friction between the vehicle 5 and the belt 13 is large, so that the vehicle 5 can be reliably secured. Can be raised.

When the bottom surface of the vehicle 5 is placed on the first conveyor belt device 10 in this manner, the vehicle 5 is pulled up as the conveyor belt device 10 travels and is transferred to the second conveyor belt device 20.

In this case, since the inclination of the second conveyor belt device 20 becomes a steep angle, the bow of the vehicle 5 is the second conveyor belt device.
When it is placed on the belt 23 of 20, since the rear end portion is placed on the first conveyor belt device 10, the center portion is floated.

However, the belt 13 of the first conveyor belt device 10
Are supported by rocking rollers 15, and the lower end portion 37 of the second conveyor belt device 20 is also supported by the rocking rollers 25, so that the belt 13 on which the front and rear ends of the vehicle 5 are placed. , 23 will sink as shown by the solid line in FIG.

Therefore, the front and rear ends of the vehicle 5 and the belts 13 and 23
Each contact area with and becomes large.

As is clear from a comparison with the case shown by the imaginary line in FIG. 8, this imaginary line shows the case where the rocking roller is not used and all the stationary rollers are used.
However, the front end and the rear end contact the belts 13 and 23 with a small area, and the center of the vehicle 5 floats greatly in the air.

In this embodiment, the front and rear ends of the vehicle 5 and the belt 13,
As each contact area with 23 increases, friction increases,
Since the front end of the vehicle 5 is strongly pulled by the belt 23 and the rear end is strongly pushed by the belt 13, the vehicle 5 can be reliably transferred onto the second conveyor belt device 20 without slipping.

Also, since the length of the center of the vehicle 5 floating in the air is shortened,
Large stress is not generated in the center of the vehicle 5, and damage is prevented.

The vehicle 5 transferred to the second conveyor belt device 20 in this way is carried along the ascending course 2 as the second conveyor belt device 20 travels.

Then, when the vehicle 5 reaches the curved portion 35 at the upper end portion of the second conveyor belt device 20, the swing roller 25 also reaches the curved portion 35.
Is provided, the contact area between the vehicle 5 and the belt 23 can be increased.

That is, as shown in FIG. 9, when the vehicle 5 reaches the curved portion 35, the central portion of the bottom surface of the vehicle 5 pushes the belt 23 to sink the swing rollers 25.

In this case, as shown by the solid line in FIG. 9, the contact area between the bottom surface of the vehicle 5 and the belt 23 becomes large. In other words, as is clear from the comparison with the case shown by the imaginary line in FIG.
This imaginary line shows the case where all of the fixed rollers are used without using the rocking roller. In this case, the bottom surface of the vehicle 5 comes into contact with the curved belt 23 in a small area, and the front end portion and the rear portion of the vehicle 5 are contacted. The ends will float greatly in the air. Therefore, the vehicle 5 swings back and forth like a seesaw, is extremely unstable, and is worried that it may swing back and slide backward on the belt 23.

However, the rocking rollers 25 ...
As indicated by the solid line in the figure, the contact area between the bottom surface of the vehicle 5 and the belt 23 increases, the vehicle 5 stabilizes, and the friction with the belt 23 increases, so that the vehicle does not slide backward.

Further, since the vehicle 5 is supported at the center portion, the contact area with the belt 23 is large, so that large bending stress does not occur at the center portion.

Therefore, the vehicle 5 is reliably pulled up, and there is no fear of damaging the vehicle 5.

The present invention is not limited to the above embodiment.

That is, in the above-described embodiment, the track is composed of the water channel 1 and the land path, but the track may be composed of only the land path.

Further, in the above-described embodiment, the first conveyor belt device 10 having a gentle inclination is provided in the portion pulled up from the water channel 1 to the land route, but the present invention is not limited to this, and in short, the pulling device may be divided into a plurality of stages. Is not restricted to.

Even when the pulling device is constituted by only one stage, similar effects can be obtained by installing rocking rollers at the lower end and the upper end like the second conveyor belt device 20.

Further, the swinging mechanism of the swinging roller is not limited to the above-described embodiment, but other springs can be configured to have the same function.

(Effect of the Invention) As described above, according to the present invention, since the rocking roller installed in the region where the gradient of the gradient track changes, the rocking roller sinks when a game vehicle is placed on it, so that the contact area between the game vehicle and the conveyor belt is reduced. Is increased, friction between the two is increased, and slippage does not occur, so that reliable pulling is possible. Moreover, since the contact area between the game vehicle and the conveyor belt is increased, a large stress is not generated in the central portion of the vehicle, and the vehicle can be prevented from being damaged.
