Abstract

PROBLEM TO BE SOLVED: To enjoy both of a speed feeling and an up-and-down motion in driving even on the same plane by providing an arm mechanism lifting/lowering a passenger seat and using rotation of a push-up tire rotating by engagement with a cam formed on a floor face for oscillating the arm mechanism. SOLUTION: In driving a gravity car, a passenger is taken aboard to the car in a platform, and then, the car is driven on a floor face 12. In this case, a passenger seat 17 is in the lowermost position, and a driving wheel 13 is driven and rotated via a toothed belt 11 by means of a traveling driving motor 10. A cam 22 is formed on the floor face 12. When the car reaches the position in which a push-up tire 23 is brought into contact with the cam 22, the push-up tire 23 is rotated, and its rotational speed is reduced by means of a speed reducing mechanism 24 while torque is amplified, and then, a short arm 21a in a lever arm 21 is oscillated via a crank 25 and a connecting lever 26. In this way during operation of the car, the passenger seat 17 is lifted/lowered to a carriage 15 via a balance link 20 and the lever arm 21.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game vehicle installed in an amusement park, a leisure land, or the like.

[0002]

2. Description of the Related Art Conventionally, various game vehicles have been proposed. For example, in a roller coaster, a vehicle travels on a track, and uses a potential energy and a speed energy to give a passenger a sense of speed and thrill.
Another game vehicle runs around the floor.

[0003]

However, the above-mentioned conventional game vehicle requires a track on which the vehicle travels, and furthermore, a rigid support is required in order to provide a height difference to the vehicle. Also, to raise the vehicle to a higher position,
There was the disadvantage that a large amount of energy was required. Also, simply running around the floor lacks a sense of speed,
I couldn't feel the thrill.

[0004] An object of the present invention is to provide a gravity car capable of enjoying a sense of speed and exhilaration while traveling on the same plane in view of the drawbacks of such a conventional game vehicle.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a driving motor for traveling, a passenger seat on which a player rides, and an arm mechanism for raising and lowering the passenger seat. The arm mechanism raises the passenger seat by the arm by reducing the rotation speed of the push-up tire that is rotated by the cam formed on the floor surface and increasing the torque, thereby increasing the potential energy of the raised passenger seat. Is converted into the traveling energy of the vehicle.

The arm mechanism includes a lever arm for supporting a passenger seat, an equilibrium link, a push-up tire,
It is characterized by comprising a speed reducer and a cam clutch.

The gravity car according to the present invention realizes a roller coaster-like bodily sensation, such as vertical movement, speed feeling, and thrill feeling while traveling on a plane, so that the user can enjoy a refreshing feeling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below.
This will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of the operation of a gravity car according to one embodiment of the present invention as viewed from a side. Here, the gravity car is a driving motor 1 for traveling.
0, drive wheels 13, casters 16, passenger seat 17, arm mechanism 18, and the like.

The gravity car has a driving motor 10 for traveling.
A pulley 19 with a clutch is fixed to the rotation shaft of the drive motor 10 for traveling. Furthermore,
The pulley 19 drives the drive wheel 13 that is in contact with the floor 12 via the toothed belt 11. Guide wheels 14 are provided before and after the drive wheels 13. In addition, the cart 15
A caster 16 is attached to the front of the vehicle. Therefore, the cart 15 is composed of the caster 16 and the drive wheel 1.
3 allows it to move on the floor 12. The pulley 19 is provided with a one-way clutch. The one-way clutch transmits power in a direction in which the traveling drive motor 10 advances the drive wheel 13, but idles when power is transmitted from the drive wheel 13 side. .

A passenger seat 17 on which a player rides is supported by an arm mechanism 18 on the cart 15. Here, the arm mechanism 18 includes a pair of left and right equilibrium links 20, a lever arm 21, and a reduction mechanism 24 that reduces the number of rotations of a push-up tire 23 that is rotated by a cam 22 formed on the floor surface to increase torque. Crank 25, connecting rod 26
And so on.

The balance link 20 connects the lower end of the passenger seat 17 and the carriage 15 to each other by a hinge. Also, the lever arm 21
Has a front end hingedly connected to a lower end of the passenger seat 17,
The base end is pinned to the carriage 15. Furthermore,
A pulley 27 is attached to the base end, and the pulley 27 is connected to a pulley 29 via a toothed belt 28.
a. The toothed belt 30 wound around the pulley 29b is wound around a pulley 13a directly connected to the drive wheel 13. The diameter of the pulley 27 is larger than the diameter of the pulley 29a. Also, pulley 2
The diameter of 9b is larger than the diameter of pulley 13a. Therefore, the lever arm 21 is connected to the pulleys 27, 29a, 29
When the drive wheel 13 is rotated via the b and 13a, the rotation speed increases.

The short arm 21a of the lever arm 21 is
It is connected to the crank 25 via a connecting rod 26. Further, the crank 25 is connected to the lifting tire 23 via a speed reduction mechanism 24. Therefore, after the rotation of the lifting tire 23 is decelerated, the lever arm 21 is driven via the crank 25 and the connecting rod 26. The push-up tire 23 has a built-in cam clutch for preventing reverse rotation, thereby preventing the tire from rotating reversely.

A pulley 27 is fixed to the lever arm 21 and rotates together with the lever arm. The pulley 27 is connected to a small-diameter pulley 29 a by a toothed belt 31. Further, the pulley 29b and the pulley 13a coaxially arranged with the pulley 29a are connected by a toothed belt 30. Here, a one-way clutch is attached to the pulley 29b, and power cannot be driven from the drive wheel 13 side, but can be transmitted only from the pulley 29b side.

Next, the operation of the gravity car constructed as described above will be described. First, a passenger is loaded on the platform, and after confirming safety, the user departs to run on the floor surface 12 as shown in FIG. At this time, passenger seat 17
Is in the lowest position. The traveling drive motor 10 drives the drive wheels 13 via the toothed belt 11.

After passing through the platform, a cam 22 is formed on the floor surface 12, and the lifting tire 23 comes into contact with the cam 22 and rotates (see FIG. 2). The rotation of the push-up tire 23 is reduced by the reduction mechanism 24 to increase the torque, and then the short arm 21 a of the lever arm 21 is driven via the crank 25 and the connecting rod 26. Then, the lever arm 21 raises the passenger seat 17 from the carriage 15 (see FIG. 3). The push-up tire 23 has a built-in cam clutch for preventing reverse rotation, so that the tire does not reverse.

When the passenger seat 17 comes to the uppermost position as shown in FIG. 4, the crank 25 rotates 180 degrees, and when pulled from the load side, the crank 25 also has a cam clutch (not shown). The power to do no longer exists. Then
The passenger seat 17 tends to drop at an acceleration due to its own weight.
On the other hand, a pulley 27 is attached to the lever arm 21, and the pulley 27 is connected to a pulley 29 a via a toothed belt 31.

Here, the diameter of the pulley 27 is
Since the diameter is larger than 9a, the number of rotations increases. Further, a pulley 29b coaxially arranged with the pulley 29a is connected to a pulley 13a attached to the drive wheel 13, and the potential energy of the passenger seat 17 is converted into velocity energy. Again, the diameter of pulley 29b is larger than the diameter of pulley 13a. Therefore, the gravity car is rapidly accelerated.

If the cam 22 formed on the floor surface 12 is not present before the passenger seat 17 rises to the uppermost position, the passenger seat 17 continues traveling while maintaining its height.
Further, when the cam 22 is formed again on the floor surface 12, the push-up tire 23 starts to rotate again, and the crank 25
The passenger seat 17 falls from a position rotated more than degrees to accelerate the gravity car.

The pulleys 27, 29a, 29b, 1
By changing the diameter ratio of 3a, the same effect as changing the down slope of the roller coaster can be obtained. Therefore, the gravity car of the present invention can experience a riding comfort like a roller coaster while traveling on the flat floor surface 12.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made based on the technical idea of the present invention.

[0021]

As described above, the gravity car according to the present invention includes a drive motor for traveling, a passenger seat on which a player gets in, and an arm mechanism for raising and lowering the passenger seat. Increases the torque by decelerating the number of rotations of the push-up tires rotated by the cams formed on the floor, thereby raising the passenger seat with the arm, and converting the increased potential energy of the passenger seat into the traveling energy of the vehicle. So you can enjoy a sense of speed and thrill with little energy. In addition, the passenger seat moves up and down while the vehicle is traveling on a plane, so that it is possible to realize the same feeling as a roller coaster.

Further, since relatively small energy used for running the vehicle is utilized and stored as potential energy, a dynamic feeling of speed can be experienced with small energy.
