Description

DETAILED DESCRIPTION OF THE INVENTION (al) Industrial Application Field This invention relates to a play equipment in which rotational motion and rocking motion are performed in parallel.

(BL Conventional Technology) Conventionally, there have been large-scale play equipment installed in amusement parks, etc., in which rotational motion and rocking motion are performed in parallel. There was something.

(C1 Problem to be solved by the invention) However, the former has a complicated structure and consumes a lot of power, and cannot be easily converted into a simple play equipment. Moreover, the rotation speed and swing width cannot be adjusted at the will of the rider. The problem was that it was not possible.

In addition, the latter requires the rider to kick the ground with his/her foot to make the rotation motion, which is not only dangerous, but also requires the rider to be distracted by both the rocking and rotation of the seesaw, making it a pleasant game. There were problems such as not being able to enjoy it.

This invention was made in response to these problems, and is a game that has a simple structure, consumes little power, and allows the rider to adjust the rotation speed and swing width according to his/her will, allowing the rider to enjoy the game comfortably. The purpose is to provide ingredients.

(Means for Solving Problem d3) In the play equipment of the present invention, the central portion of a support member having a seating portion at the end is swingably attached to a rotatably supported column, and a rotational drive mechanism is provided. The connected rotary disks are supported by a shaft body vertically attached to the center of the support member, and a rotary motion transmitting member that slides on the rotary disk and transmits its rotational motion to the support member is connected to the support member. A pedal is provided on the member and is provided near the seating portion for adjusting the contact force between the rotary motion transmitting member and the rotating disk.

(e) Function In the play equipment of the present invention, when the rotating disk is driven by the rotational drive mechanism, the rotating disk rotates relative to the ground due to the inertia of angular momentum, as seen in the so-called earth top principle. The supporting member to which the shaft supporting the rotating disc is attached becomes horizontal as it performs a precession motion (misosuri motion) in which it rotates and attempts to become horizontal while repeating a rocking motion using the center as a fulcrum. try to become Moreover, since the rotational motion of the rotating disk is transmitted to the supporting member by the rotational motion transmission mechanism, the supporting member performs a precession motion similar to that of the rotating disk. When the rider changes the amount of pedal depression from the seated portion of the support member, the contact force between the rotary motion transmission member and the rotating disk changes, the amount of rotation transmitted changes accordingly, and the rotational speed of the support member changes. When the rotational speed changes, the swing width of the support member also changes. The amplitude of this sway also changes as the rider moves and changes the position of the center of gravity.

(f) Embodiment FIG. 1 is a partially cutaway side view of a play equipment according to an embodiment of the present invention, and FIG. 2 is a plan view of the play equipment.

A column 1 is supported by an installation pressure 2 via a bearing 3 so as to be rotatable around a vertical axis Y, and a bracket 5 is attached to the upper end of the column 1 via a horizontal shaft 4. A support member 6 made of a narrow plate has a central portion fixed to the bracket 5, and a support plate 7 extending parallel to the support member 6 is also fixed to the bracket 5. A balance spring 8.8 is interposed between the support member 6 and the support plate 7. Further, a sheet 9 is provided at one end of the support member 6.
A seating portion 10 is provided, and a balance weight 11 is held at the other end of the support member 6. This balance weight 11 is attached to the horizontal axis 4 as shown by arrow A.
It is possible to increase or decrease the distance from the horizontal axis 4 by moving it toward or away from the horizontal axis 4. □Furthermore, the support member 6 is provided with a beam member 12 spanning the center thereof, and a shaft body 13 is rotatably supported between the beam member 12 and the support member 6. This shaft body 13 is perpendicular to the support member 6 and is provided at the center of the support member 6 . The rotating disk 14 is supported by the shaft 13 by fixing the central portion of the rotating disk 14 to the shaft 13. In addition, the shaft body 13
and a rotating shaft 16 of a drive motor 15 are connected by a belt 17. In this embodiment, the drive motor 15 is held by the support member 6. Reference numeral 18 denotes a rotational motion transmission member, which is an L-shaped member connected to the support member 6 via a pin 19, and has a shoe portion 20 provided at its tip.
is always in sliding contact with the rotating disk 14. Further, a pedal 21 is provided at the base end of the rotational motion transmission member 18. This pedal 21 is arranged near the seating section 10, and allows the rider seated on the seat 9 to adjust the degree of depression with his or her feet.
When the pedal is stepped more firmly, the shoe part 20 and the rotating disc 14
The contact force with the pedal increases, and when the pedal pressure is loosened, the contact pressure decreases. Therefore, depending on how much the pedal 21 is depressed, the transmission efficiency of the rotational motion of the rotary disk 14 to the support member 6 is adjusted to increase or decrease.

In such a play equipment, when the drive motor 15 is started, the rotating disk 14 begins to rotate due to the rotational force transmitted to the shaft body 13 via the rotating shaft 16 and the bell 17 of the drive motor 15, and gradually rotates. Rotation speed increases. Then, when the rotational speed of the rotating disk 14 becomes sufficiently fast (when the rotating disk 14 reaches a sufficiently high speed, the rotating disk 14 rotates while repeating a rocking motion with the horizontal axis 4 as a fulcrum due to inertia commensurate with the angular momentum (rotational energy) at that time. It performs a precession motion to become horizontal with the ground.Furthermore, since the rotational motion of the rotating disk 14 is transmitted to the support member 6 by the rotational motion transmission member 18, the support member 6 also follows the shaft of the rotational motion transmission member 18. It rotates following the rotating disk 14 while maintaining a speed difference commensurate with the contact force between the part 20 and the rotating disk 14, and at the same time, the swinging motion of the rotating disk 14 is applied to the support member 6 via the shaft body 13. As a result, the support member 6 also precesses in the same way as the rotating disk 14.The impact when the support member 6 swings is absorbed by the balance spring 8°8, so the impact is not transmitted to the rider. First, for the rider seated on the seat 9, the unique sensation caused by the precession of the support member 6 feels comfortable.

The rotational speed of the support member 6 increases by increasing or decreasing the pedal pressure of the rider's will, and decreases by relaxing the pedal 21.As the rotational speed of the support member 6 increases, the rotation speed of the support member 6 increases accordingly. As the vertical swing width of the support member 6 becomes smaller and its rotational speed slows down, the vertical swing width increases accordingly.The rotation speed of the support member 6 can be adjusted simply by adjusting the degree to which the rider depresses the pedal 21. In addition, if the rider moves his or her body to change the position of the center of gravity, the width of the swing can be changed without changing the rotational speed of the support member 6. Therefore, if the rider moves his or her own body and changes the center of gravity, the width of the swing can be changed without changing the rotational speed of the support member 6. You will be able to freely adjust the rotational speed and swing width by twisting or loosening or moving your body, which will improve the riding comfort and allow you to enjoy the game more comfortably. Note that the balance between the rider and the balance weight 11 can be maintained by changing the position of the balance weight 11 according to the rider's weight and changing the mutual distance from the horizontal shaft 4.

In this embodiment, the drive motor 15, belt 17, and shaft body 13 are an example of a rotational drive mechanism for applying rotational force to the rotating disk 14, and the drive motor 15 is provided on the support member 6. Therefore, there is an advantage that the rotational drive mechanism exhibits a speed increasing function. Note that the drive motor 15 does not necessarily need to be provided on the support member 6, and may be provided at another location.

Furthermore, the rotational force of the drive motor 15 may be directly transmitted to the rotating disk 14 without going through the shaft 13. In that case, the shaft 13 is fixed to the support member 6 and the beam member 12, and the rotation The disk 14 may be rotatably supported by the shaft body 13.

(g1 Effect of the invention According to this invention, as shown in the embodiment, it is possible to provide a simple play equipment with a simple structure and low power consumption, and in addition, the rider can adjust the amount of pedal depression. By simply moving your body a little, you can easily adjust the rotation speed and swing width to suit you, so you can enjoy the game comfortably without any danger.
