Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring-shaped ferris wheel in which a passenger in a cabin can enjoy a view by rotating around from a low place to a high place through a low place.

[0002]

2. Description of the Related Art In a conventional annular ferris wheel, for example, as shown generally by reference numeral 50 in FIG.
A large annular wheel 51 supported by 8 and having a large number of view cabins 55 mounted at regular intervals in the circumferential direction.
Are rotated by a rotation drive device 59. Each view cabin 55 is suspended by its own weight from a beam 53 of a triangular suspension truss 52 protruding from the large rotation wheel 51 via a pin joint. Therefore, unless the cabin 55 is exposed to a strong wind or the passenger does not walk inside the cabin 55, the cabin 55 has the weight of the cabin itself or the weight of the passenger and the chair, etc. It is designed to be maintained almost horizontally at the bottom of the.

[0003]

In other words, the conventional ring-shaped ferris wheel 50 has a structure in which the cabin 55 sways when a strong wind is received or the passenger walks inside the cabin 55. Besides, there is a problem that the suspension truss 52 is located on both side surfaces of the cabin 55 when the cabin 55 reaches the upper portion of the annular guide wheel, and the suspension truss 52 interferes with the view and the view deteriorates. There was a fear of the problem. Further, unless the ferris wheel has a considerably large diameter, it is necessary to get on and off within a short time after the cabin 55 arrives in the platform.

In order to solve the above-mentioned problems of the prior art, the present invention eliminates the suspension truss by directly holding the cabin on the rotating wheels, and can always secure a good view on the side of the cabin. It is a first object of the present invention to provide a ring-shaped ferris wheel in which the posture of a cabin can be forcibly maintained horizontal or at a predetermined inclination angle to eliminate shaking due to suspension.

A second object of the present invention is to provide an annular ferris wheel which has a wide horizontal portion on the lower part platform of the ferris wheel and has a smaller diameter to increase the number of passengers and to increase the transportation capacity. Is.
