Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rotating observation deck installed in an amusement park, an exhibition hall, an event hall, or the like.

(Prior Art) A rotating observatory was used to file a device that allows the inner and outer perimeters to be viewed, and was filed in Japanese Patent Application No. 50-28438.
Published in -42967. In the above-mentioned Japanese Utility Model Application No. 50-28438, a plurality of small discs that are rotatably supported by bearings on the rotating carriage rotate as the rotating carriage rotates. In detail,
The friction wheel attached to the lower part of the small disc comes into contact with the annular friction plate as the rotary carriage rotates,
The small disk turns. A passenger sitting on a chair mounted on the small disk can view the inner circumference and the outer circumference of the rotating carriage by the rotation of the small disk accompanying the rotation of the rotating carriage. However, in the above-mentioned Japanese Patent Application No. 50-28438, since the small disc on which the passenger seats are attached is rotated due to the friction between the friction wheel and the annular friction plate, the rotating position of the small disc is changed. It is difficult to specify, and the rotation angle is likely to be an indefinite angle. The passengers can see the view of the inner and outer circumferences of the rotating carriage in the direction in which the passengers are facing. Depending on how the small disc is turned, the passengers cannot see the view. Is left and ends.

(Problems to be solved by the invention) It is an object of the present invention to provide a revolving observatory that allows passengers to observe the entire inner and outer views of the revolving carriage while sitting on a chair.

(Means for Solving the Problem) A central shaft extending downward is fixed to a plurality of small circular plates rotatably supported by a rotary carriage, and a boss portion and a central shaft extending downward are attached to a lower end portion of the central shaft. Fix the follower with the arm part that extends horizontally 180 ° around the boss part,
A driven roller having a vertical center pin is attached to both ends of the driven joint.

To prevent the small disc from rotating relative to the rotating carriage,
A guide plate having a guide surface, which is an inner peripheral portion of a cylinder having the same center as that of the rotary carriage, and a cam groove portion for rotating the small circular plate by 180 ° relative to the rotary carriage are attached to the base frame base. . The cam groove portion is a cam groove portion that first guides the driven roller, which is attached to the leading end portion in the traveling direction of the two driven rollers that are attached to both end portions of the driven portion, to the outside, and the driven roller that is the leading end. After the roller is moved outward and the follower is formed at a right angle to the traveling direction, the driven groove moved outward is moved to the rear of the central axis of the small disc and the cam groove portion. Become.

The radius of curvature of the guide surface, which is the inner peripheral portion of the cylinder, is (R + r + α), where R is the distance between the center of rotation of the rotary carriage and the center of the small disk and r is the radius of the driven roller.
Here, α is a clearance dimension.

(Operation) The small disk rotatably supported by the rotating carriage moves together with the rotating carriage when the driven roller of the driven joint is guided by the inner peripheral guide surface of the cylinder. There is no relative rotation.

When the driven roller attached to the leading end of the follower moves into the cam groove that guides the driven roller at the leading end outward, the small disc moves relative to the rotary carriage. start. That is, as the rotating carriage rotates, the driven roller, which was the head of the driven section, is gradually guided to the outside,
At the same time, the driven roller located at the rear of the driven section is gradually moved inward.

After the follower is formed at a right angle to the direction of travel, the driven roller guided outward travels in the cam groove so as to be pulled by the center axis of the small disc, and comes into contact with the inner peripheral surface of the annular cam plate. Is located in the rear part of the progression of the follower.

The driven roller, which was attached to the front end of the follower and moved to the rear of the follower at the cam groove, allows the small disc to rotate as the rotary carriage rotates. While being supported by the dolly, it makes a relative rotation of 180 ° with the rotating dolly.

Due to the rotation of the small disc, the passengers seated on the seat attached to the small disc facing the inner circumferential direction of the rotating carriage face the outer peripheral direction, while the passengers facing the outer peripheral direction You will be able to see the inner circumference.

The passenger on the small disk needs two rotations of the rotating carriage to view the entire inner and outer views of the rotating carriage from the front.

While the rotating cart makes two turns, passengers on the small disk can see the entire landscape inside and outside the rotating cart from the front.
