BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motion device in a three-dimensional space that is capable of free movement in a three-dimensional space and can be applied to amusement facilities in amusement parks, astronaut training facilities, and the like.

[Prior Art] For example, roller coasters installed in amusement parks have tracks arranged three-dimensionally, and the guide rollers of the cart are engaged with the rails on the track to prevent the cart from coming off the rails. I have to. Since the cart itself does not have any driving force, the cart is hoisted up to the highest point of the track using chains, etc., and then moved from the highest point using gravity. On the other hand, NASA (National Aeronautics and Space Administration) and NASDA (Space Development Agency) have astronaut training facilities that provide physical training for astronauts to withstand high acceleration during launch and landing. A centrifugal force generator is a direct device for performing such training. This device is configured to attach a cabin for people to board to the tip of an arm, and generate centrifugal force in the cabin by rotating the arm. Additionally, the Marshall Space Flight Center Visitor Center in the United States and Space World in Japan have educational and experiential learning facilities where the general public can experience astronaut training, but their performance exceeds that of an astronaut training facility. does not exist.

[Problem to be Solved by the Invention] Conventional amusement facilities such as roller coasters as mentioned above are very large and have complicated loops in order to attract the interest of amusement park guests. However, because the trajectory itself is fixed, the movement of the cart is limited, and amusement park visitors are looking for something more thrilling and with interesting movements. Furthermore, in the conventional equipment used in astronaut training facilities, etc., the rotating surface of the cabin is a horizontal plane, and the centrifugal force is only directed in one direction toward the outside of the cabin, making it impossible to conduct sufficient training. As a training device, it is desirable that the direction and magnitude of centrifugal force can be changed freely.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to obtain free movement in a three-dimensional space that is not restricted by orbits, and to freely control the direction and magnitude of centrifugal force. The object of the present invention is to provide a controllable three-dimensional space movement device.

[Means for Solving the Problems] The present invention provides a first
A linear motor is provided on the inner periphery of the ring so as to be movable in the circumferential direction, and the first ring is inserted into the second ring so that their rotation center axes intersect, and the linear motor is used to move the first ring on the inner periphery of the second ring. The second ring is inserted into the third ring so that their rotational axes intersect, and the second ring is movable along the inner circumference of the third ring by a linear motor. .

[0006]

[Operation] The second ring is rotated by a linear motor with respect to the third ring, the first ring is rotated by the linear motor with respect to the rotating second ring, and an imaginary rotating body is formed by the first ring. The cart moves along the surface of this imaginary rotating body, allowing free movement in three-dimensional space that is not restricted by orbits. Various movement patterns can be obtained by combining the speeds of the three linear motors and further changing the speed of each linear motor during movement. The centrifugal force acting on the cart is
This is the sum vector of the centrifugal force of the ring, and the direction and magnitude of the sum vector can be changed by changing the speed, stopping, or reversing the three linear motors.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on an illustrative embodiment. As shown in FIGS. 1 and 2, the three-dimensional space movement device of the present invention mainly includes a cart 1, a first ring 2-1,
, a second ring 2-2, and a third ring 2-3, the cart 1 rotates around the inner circumference of the first ring 2-1 by a linear motor 3-1, and the first ring 2-1 rotates around the inner circumference of the first ring 2-1 by a linear motor 3-1. 2 around the inner circumference of the second ring 2-2, and the second ring 2-2

As shown in FIG. 3, the cart 1 is a carrier for carrying a person, and is guided movably in the circumferential direction along the inner circumference of the first ring 2-1 by a guide support mechanism 4-1. It is supported and propelled by a linear motor 3-1. The linear motor 3-1 has a moving element (for example, a primary coil) 5 protruding from the bottom center of the cart 1, and a stator (for example, a permanent magnet) 6.
are disposed continuously in the circumferential direction on the inner peripheral surface of the first ring 2-1, and the cart 1 is driven by electromagnetic force. Guide support mechanism 4
-1 consists of two rails 7 and a 3 that rolls on these rails.
It is composed of one set of guide rollers 8. The rail 7 has, for example, an L-shaped cross section with a flange projecting outward, and is disposed outside the stator 6. The guide roller 8 is attached to the bottom of the cart 1 via a support bracket 9, and by sandwiching the flanges of the rail 7 between the two rollers, the gap between the slider 5 and the stator 6 is appropriately set, and the cart 1 is The remaining rollers are prevented from coming off the ring, and the remaining rollers are brought into contact with the flange end face from the outside, thereby preventing lateral vibration. In addition, a current collector 10 is provided on the side of the cart 1, and a power supply overhead wire 1 is provided at a corresponding location on the first ring 2-1.
1 is arranged so that a collector 10 can slide to collect current, so that power can be supplied to the cart 1 from the first ring 2-1 side.

The centers of the first rings 2-1 are aligned within the second ring 2-2, which has a larger diameter, and
The two rings are inserted so that their rotation center axes are perpendicular to each other (see FIG. 2) to form an inscribed state, and as shown in FIG. It is guided and supported so as to be movable in the circumferential direction, and is propelled by a linear motor 3-2. The mover 5 of the linear motor 3-2 is the first
The stator 6 is provided protrudingly at the contact point on the outer circumferential surface of the ring 2-1, and the stator 6 is disposed continuously in the circumferential direction on the inner circumferential surface of the second ring 2-2. 5 and stator 6. The guide support mechanism 4-2 can be the same as the guide support mechanism 4-1 of the cart 1. In addition, one set each of a collector 10 and a power supply overhead wire 11 are arranged on the left and right sides of the second ring 2-2, so that power can be supplied from the second ring 2-2 side to the first ring 2-1 and the cart 1. do it like this.

Similarly, the second ring 2-2 is connected to the third ring 2.
The third ring 2-3 is inserted into the third ring 2-3 so that their centers coincide with each other and their respective rotational axes are perpendicular to each other to form an inscribed state, and as shown in FIG.
It is guided and supported so as to be movable in the circumferential direction along the inner periphery of 3, and is propelled by a linear motor 3-3. Linear motor 3-
The movable element 5 and the stator 6 of No. 3 are also arranged in the same manner as the first ring 2-1, and the second ring 2-2 is caused to run by the movable element 5 and the stator 6. In addition, the collector 10 and the power supply overhead wire 1

[0011] Furthermore, three rings 2-1, 2-2, 2-
3 are arranged so that their centers coincide,
The arrangement is not limited to this, and each center may be shifted as shown in FIG. In addition, each ring is arranged so that its rotation center axis is perpendicular to the ring to be inserted.
It is also possible to arrange them at an angle so that their rotation center axes intersect at an acute angle.

Furthermore, what is shown is an example in which three single-phase linear motors are used as the linear motors, and these three single-phase linear motors are individually controlled. The 6-wire power supply overhead wire for one vehicle is connected to the second ring 2-2, the 4-wire power supply overhead wire for two vehicles is connected to the second ring 2-2, and the first ring 2-2 is equipped with a 4-wire power supply overhead wire for two vehicles.
-1 has a two-wire power supply overhead line for one vehicle. 3
It is also possible to drive the linear motors of the stands at the same time, and in this case, each ring can have two power supply installations. Furthermore, when using a three-phase linear motor, or when sending necessary power and signals to the cart, additional power supply overhead wires are required. Note that it is also possible to send signals wirelessly.

[0013] As the linear motor, a linear synchronous motor, a linear induction motor, etc. can be used. In the case of a linear synchronous motor, it is possible to use a combination of a primary coil in the mover 5 and a permanent magnet in the stator 6 as in the illustrated embodiment, but there are also other combinations in which the reverse combination is used, and in each case, a permanent magnet is used. Another possibility is to replace it with an electromagnet. In the case of a linear induction motor, the mover 5 is provided with a primary coil and the stator 6 is provided with a secondary conductor, or vice versa, the mover 5 is provided with a secondary conductor and the stator 6 is provided with a secondary conductor.
A primary coil will be installed at the Needless to say, the power supply method differs slightly depending on these combinations.

In the above configuration, when each linear motor 3-1, 3-2, 3-3 is driven, the first ring 2-1 rotating inside the rotating second ring 2-2 causes
An imaginary sphere having a diameter of the first ring 2-1 is formed,
The cart 1 moves along the surface of this sphere, providing movement in a three-dimensional space. Each ring 2-1, 2-2, 2-3
If the centers of the rings are concentrated at one point, an imaginary sphere as described above will be formed, but if the centers of each ring are different, the imaginary solid that will be formed will have a very complex shape.
Complex three-dimensional motion will be obtained. Furthermore, in any case, the movement locus of the cart 1 changes infinitely depending on how the speeds of the three linear motors are combined. Further, if the speeds of the three linear motors are changed during movement, even more movement patterns can be obtained.

[0015] The centrifugal force acting on the cart 1 is
This is the sum vector of the centrifugal forces of the first ring 2-1 and the second ring 2-2. By changing the speeds of the three linear motors, the centrifugal force of each can be changed to change the magnitude and direction of the combined vector. Furthermore, by stopping one or two linear motors or reversing the direction of propulsion of the linear motors midway through, the direction and magnitude of the sum vector can be greatly changed. Note that the use of a linear motor has the advantage that the cart can be started and stopped at high acceleration and deceleration, and can be stopped at any desired position.
