In FIG. 9, the riding rod 2 is set to rotate in the direction of the arrow M, A, B, C, and D indicate the rotation position of the riding rod 2, and the position A is at the lowest position. In this case, the position B is at a position away from the platform P (front), the position C is at the uppermost position, and the position D is at a position reaching the platform P. And the to-be-detected body 4 is arrange | positioned as follows so that each position AD of the riding rod 2 can be detected. If the angle (rotation angle) by which the carriage 2 is rotated in the direction of arrow M with reference to the lowest position A is θ, the rotation angles θ at the positions B, C, and D are α, β, Let γ.

FIG. 10 is an explanatory simplified view of the suspension shaft 1 viewed from the axial direction, and an arrow N indicates a vertically downward direction. First, FIG. 10A shows a case where the riding rod 2 is at the position A. At this time, the detected body 4 a is attached to the lowermost end of the outer periphery of the suspension shaft 1. Next, when the car 2 is rotated by the angle α (in FIG. 9) and moved to the position B, the detected object 4a is also rotated from the vertically downward N by the angle α as shown in FIG. At this time, the detected body 4 b is attached to the lowermost end of the outer periphery of the suspension shaft 1. Further, when the riding rod 2 is rotated by the angle β and moved to the position C, as shown in FIG. 10C, the detected body 4a is rotated by the angle β, and at this time, the detected body 4c is moved to the outer periphery of the suspension shaft 1. Attached to the bottom end. Similarly, in FIG. 10 (d), when the riding rod 2 is moved (rotated by an angle γ) to the position D and the detected body 4a is rotated by the angle γ, the detected body 4d is attached to the suspension shaft 1. Attached to the lowest end of the outer periphery.
In this way, detected bodies 4a, 4b, 4c, and 4d that detect the positions A, B, C, and D are installed. The detected bodies 4 corresponding to the positions A, B, C, and D to be detected are 4a, 4b, 4c, and 4d, respectively.

  The ferris wheel of the present invention is not limited to the above-described embodiment, and although not shown, the sensor 7 may be attached to a part of the circumference of the rotating ring 5 without being attached to the weight member 12. For example, the sensor 7 can be freely attached to the upper end portion of the rotating ring 5 at a position opposite to the weight member 12 via an attachment member. Further, the guide ring 9 is not attached to the suspension shaft 1, but two annular guide rails are directly formed on the outer peripheral surface of the suspension shaft 1, and the rotation ring 5 is rotatably fitted between the two guide rails. Is also free.

A method (action) for using the ferris wheel according to the present invention will be described.
In FIG. 9, the case where it is detected that the riding rod 2 exists at the lowest position A will be described.
First, the detected body 4 is attached to the lowermost end of the outer periphery of the suspension shaft 1 as shown in FIG. When the riding rod 2 rotates (in the direction of arrow M shown in FIG. 9), the suspension shaft 1 rotates relative to the riding rod 2, and the detected body 4 and the guide ring 9 also rotate accordingly. At this time, the rotating ring 5 rotates relative to the guide ring 9 while always holding the weight member 12 and the sensor 7 attached thereto so as to be positioned at the lowermost end of the rotating ring 5. Then, when the riding rod 2 rotates once and reaches the lowest position A again, the detected body 4 also rotates once and reaches the lowermost end of the suspension shaft 1, and the sensor 7 detects the proximity of the detected body 4. . Thereafter, when the riding rod 2 continues to rotate, the sensor 7 similarly detects the detected object 4 every time the riding rod 2 reaches the lowest position A.

As described above, the ferris wheel of the present invention is the ferris wheel including the riding rod 2 that is rotatably suspended on the horizontal suspension shaft 1 fixed to the rotating frame 10. The position detecting means 3 includes a detected body 4 fixed to the outer peripheral surface of the suspension shaft 1 and a rotating ring 5 that is rotatably attached to the suspension shaft 1 via a roller 6. A weight member 12 attached to the rotating ring 5, a sensor 7 attached to a part of the circumference of the rotating ring 5 and detecting the approach of the detected object 4, and the rotating ring 5 is an axis of the suspension shaft 1. Since the position deviation prevention means 17 for preventing movement in the center direction is provided, the rotation position (rotation angle) of the riding rod 2 can be easily detected.
Accordingly, in FIG. 9, for example, a guidance broadcast of a view that can be viewed when the rider 2 is at the uppermost position C can be started, and when the rider 2 is at the lowermost position A, from the valve 34 below the rider 2 It is possible to set so that drainage is discharged. Furthermore, it can be set so that the door lock is released when the closed state of the door is confirmed at the position B where the carriage 2 is separated from the platform P and reaches the platform P. Further, when the riding rod 2 reaches a desired position, the illumination arranged on the riding rod 2 can be turned on and blinking, or the color of the illumination can be changed.
Further, since the rotating ring 5 does not move in the axial direction of the suspension shaft 1, the sensor 7 can be relatively close to the detected body 4 without being displaced, and the predetermined position of the riding rod 2 can be surely secured. Can be detected.

  Further, since the detected body 4 is wound around the suspension shaft 1 by the band member 8, the detected body 4 can be easily installed on the existing suspension shaft 1 and can be installed at a desired position of the suspension shaft 1. That is, the detected object 4 can be attached to a suitable position of the suspension shaft 1 that does not interfere with other devices (such as the air conditioner 21). Furthermore, the direction of the detected body 4 can be easily changed according to the position of the riding rod 2 to be detected.

  The misalignment prevention means 17 includes a guide ring 9 fixed to the suspension shaft 1 so that the roller 6 attached to the rotating ring 5 can roll into a groove 11 formed on the outer peripheral surface of the guide ring 9. Since it is fitted, the rotating ring 5 does not move in the axial direction of the suspension shaft 1 and can rotate smoothly and stably with respect to the suspension shaft 1. As a result, the sensor 7 can be relatively close to the detected body 4 without being displaced, and the predetermined position of the riding rod 2 can be reliably detected.

Further, a control unit 13 for receiving a signal from the sensor 7 is attached to the riding rod 2, and an intermediate portion of the cable 14 that electrically connects the control unit 13 and the sensor 7 is attached to the cable 14 and the control unit 13. An imaginary line L connecting the position X and the axis Y of the suspension shaft 1 is attached to a portion Z that overlaps the circumference of the rotary ring 5 when viewed from the axial direction of the suspension shaft 1, and the cable 14 is connected to the rotary ring. 5 and the attachment position X between the attachment portion Z and the control portion 13 are loosely suspended, so that a predetermined position of the riding rod 2 can be reliably detected.
That is, when the control unit 13 swings around the suspension shaft 1 together with the carriage 2, the change in the distance between the attachment portion Z and the mounting position X can be minimized, so that the cable 14 It is possible to prevent displacement of the sensor 7 without pulling the rotating ring 5 and the sensor 7.

  The rotating ring 5 has a pair of half-arc-shaped half-ring bodies 15 and 15 and is formed by connecting both ends of the half-ring bodies 15 and 15. Since it has a pair of arc-shaped split ring bodies 16 and 16 and is formed by connecting both ends of the split ring bodies 16 and 16, the rotating ring 5 and the guide ring 9 are connected to the existing suspension shaft. 1 and can be installed at a desired position of the suspension shaft 1. That is, the rotating ring 5 and the guide ring 9 can be attached to a suitable position of the suspension shaft 1 that does not interfere with other devices. Moreover, the rotating ring 5 and the guide ring 9 can be manufactured easily.
