Description

[Detailed Description of the Invention] The present invention relates to a rotating swing, and more specifically, to an amusement machine in which a carrier carrying a large number of people can rotate 360 degrees.

The above-mentioned rotating swing is known in Japanese Patent Application No. 56-21618 as a prior art. However, this prior art
Since the carrier is supported by two arms arranged in parallel, the arms are unsightly and lack a sense of comfort. Also, since it was time-consuming and expensive to construct, there was a distaste for making it larger.

In view of the above-mentioned circumstances, the present invention aims to provide a rotating swing consisting of one arm, and one embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a column, and a hydraulic motor 2, which can be rotated in forward and reverse directions, is used as a rotational drive source. Reference numeral 3 denotes a single arm that can rotate 360 degrees, and is rotatably attached to the support column 1 through a pivot shaft 4 approximately in the center.

A weight 5 is fixed to one end of the arm 3 so that its position can be moved 5' as necessary.
It is adjusted to balance the weight of the carrier. On the other hand, there is a carrier shaft 6 at the other end of the arm 3, and a carrier 7 for a swing-type vehicle is pivotally attached to the carrier shaft 6 by a bearing 8, and the carrier 7 is mounted in the longitudinal direction L in the rotation direction of the arm 3. Therefore, when the arm 3 is rotated about the rotation axis 4, the longitudinal end of the vehicle will draw an elliptical orbit.
The vehicle has four people lined up facing each other in the longitudinal direction L, and three people lined up in the transverse direction S, so the total
It is designed to accommodate 12 passengers.

The pivot shaft 4 has two fixed sprockets 9, 9.
is fixed to the carrier shaft 6, and the same two rotating sprockets 10, 10 are attached to the bearing 8.
Chains 11, 11 are wound around the sprockets 9, 10 and 9, 10 between the two sprockets. Therefore, while the arm 3 rotates once, the rotating sprockets 10, 10 rotate exactly once, so the carrier 7 is always maintained in its normal position without being turned upside down. Note that tension devices 12, 12 are provided at the intermediate portions of both chains 11, so that the tension of the chains can be adjusted.

The rotating swing of the present invention is performed by reducing the operation of the hydraulic motor 2 through a gear and a bevel gear, and rotating one arm that is pivotally attached to a pivot shaft bearing. It rotates between 10 and 12 revolutions per minute, and the arm is small, about 7 meters long, so it has the advantage of being able to be installed on rooftops, etc.

In addition, since the two parallel arms of the conventional swing are removed, the swing has a good view and is comfortable, and the manufacturing cost is low, making it a useful and practical rotating swing.
