Description

[Detailed description of the invention] This invention is a type of amusement ride installed in amusement parks, etc., and is mainly called a somersault rocket, in which the player is placed on a capsule-shaped body and somersaults while drawing an arc in space. This article relates to a very thrilling somersault game device.

Conventionally, this type of somersault game device has a configuration as shown in FIG. This has a fixed shaft 2 protruding from the upper end of the column 1, and a drive shaft tube 4 with a sprocket 3 is provided around the fixed shaft 2. This drive shaft tube 4 connects a drive source 5 at the upper end of the column 1 to an output shaft 6. It is designed to be rotationally driven via a sprocket 7 and a drive chain 8, and a plurality of support arms 9 are provided radially protruding around the drive shaft cylinder 4 so as to rotate together with the drive shaft cylinder 4. A body 10, in the form of a rocket capsule, on which a passenger can be fixedly placed on an internal seat (not shown) is rotatably supported at the tip of the body 10, and a fixed crank 11 is provided at the tip of the fixed shaft 2. A chain 14 is hung between a sprocket 12 provided near the tip of the support arm 9 and a sprocket 13 provided on the body shaft, one end of which is connected to the chain 14 via a pin 15, and the other end is connected to the fixed crank 11. pin 11a
A body attitude control rod 16 is connected to the drive shaft cylinder 4, and as the drive shaft cylinder 4 rotates, the body 10 somersaults around the drive shaft cylinder 4 along a substantially vertical circumference via the support arm 9. At the same time, the pin 11a of the fixed crank 11 is rotated by the rotation of the drive shaft cylinder 4.
Body posture control rod 1 that rotates around
6 begins to reciprocate in a straight line, causing the chain 14 to reciprocate and rotate, thereby causing the body 10 to support the support arm 9.
It becomes possible to control the posture by rotating (rotating) relative to the object. In other words, the body 10 is controlled to rotate (rotate) while somersaulting along a substantially vertical circumference, and is normally oriented up and down with respect to the top and bottom at the lowest and highest positions of the rotation.

In such a conventional somersault game device, the chain 14 is controlled by reciprocating a long rod 16 via the crank 11 to control the attitude of the body 10.
Since a pure mechanical means such as rotating the rod 14 is used, the reciprocating force of the rod 14 by the crank 11 is directly transmitted to the chain 14, and considerable shock occurs during starting and stopping, causing damage to the inside of the body 10. There were problems such as causing discomfort to the passengers and causing the chain 14 etc. to loosen or rattle more quickly, making it impossible to maintain proper posture control.

In addition, the posture control means using the long rod 16 has a strong control force in the tensile direction, but is weak in the compression direction (extrusion direction).
The rod 16 needs to be quite strong and thick. Moreover, since the force transmission will not be successful unless the rod 16 is parallel to the chain 14 which is perpendicular to the body axis, the intermediate part of the body 10 in the longitudinal direction is pivotally supported on the tip of the support arm, and the intermediate body axis is interlocked with the rod 16. It is necessary to provide a structure in which the rotation is controlled by a chain 14 that is supported at one point in the middle of the body. For this reason, it is nearly impossible to install a large body that accommodates a large number of people with the conventional attitude control means using the long rod 16, and the rod 16 is unnecessarily made thicker than necessary to accommodate the weight of the large body. Conventionally, the use of such a complicated mechanism would cause problems such as detracting from the aesthetic appearance of the game device, so conventionally the device was limited to a small body capable of seating at most four people. Therefore, because these small bodies have a small capacity and are small in size, they are unable to handle large numbers of users, especially on Sundays and holidays, when amusement rides are booming among young people as in recent years. However, the drawbacks were that customers had to wait in line for long periods of time, and it was not possible for many people to ride in the same vehicle at once and enjoy the ride to the fullest.

Therefore, as a recent trend in amusement facilities, there has been a call for an increase in the number of participants, and this somersault amusement device has also come under pressure to meet this need, so more than 10 guests can ride on one body at the same time. There is an urgent need for larger bodies, and for this reason, there is a strong desire to develop a means for controlling body posture that is different from conventional means.

This invention was created in view of the above circumstances, and its purpose is to use a hydraulic system instead of using a long rod as in the past, so that all of the above-mentioned drawbacks can be easily and favorably improved. Another object of the present invention is to provide a somersault game device having a very advantageous body attitude control means that can also be used with a large body.

An embodiment of this invention will be described below with reference to FIGS. 2 to 4. In the figure, 17 is a large pillar erected on the ground, 18 is a drive source with a built-in motor and reducer (not shown) installed at the upper end of the pillar 17, and 19 is a horizontal structure that can be directly rotated by the drive source 18. The tip of the drive shaft 19 is supported by the upper end of an auxiliary column 20 erected from the ground in an inverted V shape. 21A, 21B, 21C, and 21D are attached to the drive shaft 19 around the boss 22 fitted on the drive shaft 19.
The support arms 21A and 21B each have a radially protruding support arm so as to rotate together with the support arm 21A and 21B.
21C and 21D each form a pair, and the distal end portions of each pair are bent and parallel to each other at a predetermined interval. 23A and 23B are large bodies that can accommodate more than 10 customers at a time, and this body 2
3A and 23B are rotatably (rotated) supported between the parallel ends of the supporting arms 21A, 21B, 21C, and 21D of the above-mentioned pair via front and rear end shafts 24, 24, respectively. .

Here, one support arm 21 of each set serves as posture control means for both bodies 23A, 23B.
One main hydraulic cylinder 25A, 25B is attached to each of the main hydraulic cylinders 25A, 25B near the proximal end of B, 21D, that is, near the drive shaft 19, via a mounting pin 26. Further, a rotary motion reciprocating mechanism 27 is provided around the drive shaft 19 to cause the piston rods 25a, 25b of the main hydraulic cylinders 25A, 25B to reciprocate by pulling or pushing them by the rotation of the shaft 19. In other words, this mechanism 27 consists of an eccentric cam 29 attached to a fixed shaft cylinder 28 that is fixed to the auxiliary column 20 and slidably fitted on the outer periphery of the drive shaft 19, and a pair of eccentric cams 29 that are individually rotatably slidably fitted on the outer periphery of the eccentric cam 29. The piston rod 25a of the main hydraulic cylinder 25A is connected to one of the cam rings 30A, and the piston rod 25b of the main hydraulic cylinder 25B is connected to the other cam ring 30B. On the other hand, auxiliary hydraulic cylinders 31A and 31B are fixedly installed at the distal ends of the support arms 21B and 21D, and these are connected to the main hydraulic cylinder 25 on the arm side.
Two hydraulic pipes 3 are connected to A and 25B.
2 and 32, which are connected internally as shown in FIG. In addition, a sprocket 33 is attached to the body shaft 24 at the distal end of the support arms 21B and 21D.
and both bodies 23A, 23B
A sprocket 34 is also fixed to the rear end shafts 24, 24, respectively, and endless chains 35A, 35B are rotatably hung on both sprockets 32 and 34 and 33 and 34.
B is connected to the tips of the piston rods 31a, 31b of the auxiliary hydraulic cylinders 31A, 31B by pins 36, respectively. Note that each auxiliary hydraulic cylinder 31 is arranged so that the straight portions of the chains 35A, 35B that are orthogonal to the body axis 24 are parallel to the piston rods 31a, 31b, allowing for smooth power transmission.
The directions of A and 31B are set.

Now, to describe the operation of the somersault game device having the above-mentioned configuration, the drive shaft 19 driven by the drive source 18
As a result of the rotation, the large bodies 23A, 23B are rotated around the drive shaft 19 on a vertical circumference with the support arms 21A, 21B and 21C, 21D facing each other with a 180 degree offset. It begins to repeat somersault turns along the coast. The piston rods 25 of the main hydraulic cylinders 25A, 25B rotate together with the support arms 21B, 21D during this rotation.
a, 25b rotate around the eccentric cam 28 of the rotary motion reciprocating conversion mechanism 27 together with the cam rings 30A, 30B, so that the piston rods 25a, 25
b is reciprocated by being pulled or pushed against the cylinder. In addition,
The piston rods 25a and 25b are arranged oppositely, so that when one of them is pulled toward the cylinder and moves forward, the other is pushed in and moves back and forth, thus making one reciprocating motion per rotation. In this way, the piston rods 2 of the main hydraulic cylinders 25A, 25B
5a and 25b reciprocate, internal pressure oil passes through the hydraulic pipes 32 and 32 to the auxiliary hydraulic cylinder 31.
A, 31B, and the piston rods 31a, 31b of the auxiliary hydraulic cylinders 31A, 31B.
As a result, the chains 35A and 35B are reciprocated by a predetermined stroke, and are connected to the large body 23 through the body shaft 24.
Appropriate attitude control is performed while turning while forcibly reciprocating (rotating) A and 23B. In other words, as shown in the figure, one body 23A, which is turning upward from the lowest position, is gradually rotated (rotated) 180 degrees to the left in its direction of travel, and when it reaches the highest position, it is tilted with respect to the top and bottom. It assumes a normal vertical posture without turning upside down or upside down, and when turning downward from the top position, it gradually rotates 180 degrees to the right in the direction of movement (rotation).
At the lowest position, the body is forced to return to its normal vertical position with respect to the sky and the earth. The other body 23B also gradually moves 180 degrees to the right when turning downward from the top position.
It is rotated (rotated) to a normal posture at the lowest position, and gradually moves to the left when turning further upwards.
It is rotated 180 degrees and returns to its normal posture at the highest position. In this way both bodies 23A, 23B
The body begins to somersault and turn around the drive shaft 19 while its attitude is controlled, and the sudden shock caused by the attitude control force applied to the bodies 23A and 23B at the time of starting and stopping the turning movement is alleviated by the hydraulic pressure, and the bottom There is no shock when the direction of the attitude control force is reversed at the top position and the top position, eliminating discomfort for passengers. Also, auxiliary hydraulic cylinders 31A, 31B
Since the orientation of the piston rods 31a and 31b can be set parallel to the chains 35A and 35B, the bodies 23A and 23B as shown in the figure can be freely set.
Even when the front and rear ends of the rod are supported, the posture control force from the rotary motion reciprocating conversion mechanism 27 can be easily and smoothly transmitted to the bodies 23A, 23B, and there is little wear and tear on the rod pins and chains, and the occurrence of loosening and rattling can be maintained properly over a long period of time. Posture control becomes possible. Furthermore, as mentioned above, the bodies 23A and 23B can be supported at both the front and rear ends, so there is no problem in terms of support strength even in a fairly large vehicle that can accommodate more than 10 passengers at a time. It can be done reliably using hydraulics, eliminates the need for an unnecessarily large and complicated control force transmission mechanism, and does not detract from the aesthetics of the amusement device, allowing customers to board in large numbers at once and enjoy the thrill. You will be able to play with it.

Note that this invention is not limited to the above-mentioned embodiment, and the number of support arms and the number of bodies can be changed as appropriate. However, the driving shaft 19 may be provided at an angle so that the driving shaft 19 can be rotated on a slightly oblique circumference.Furthermore, the driving shaft 19 can be rotated while changing its direction to perform a rolling operation. It is also possible to add .

Furthermore, the pair of main hydraulic cylinders 25A and 25B may be replaced with one tandem type hydraulic cylinder (not shown), and the rotary motion reciprocating conversion mechanism 2
7 may be something like a crank.

This idea was developed as detailed above, and by transmitting the body posture control force to the chain hydraulically using main and auxiliary hydraulic cylinders, all the problems of the conventional method using long rods can be solved at once. This is very smooth, eliminates discomfort such as shock, and enables proper control over a long period of time.Also, the direction of transmission of the posture control force can be freely set, so there is no need to add an unnecessarily complicated mechanism. However, the posture of the body can be controlled without any problems by the support at both ends.
With this, a very advantageous somersault game device can be obtained, as the body can be used as a large body for entertaining a large number of customers at once.
