Abstract

PURPOSE:To cause a subject to be turned up and down over a wider angle range than usual and also rotate the subject in its horizontal direction. CONSTITUTION:A plurality of permanent magnets 13 are arranged in the pattern of a check on the outer periphery of the bottom portion 13 of a spherical subject to be held (e.g. a flight simulator 11) in such a manner that different magnetic poles are arranged alternately. Also a plurality of electromagnets (14 and 15) are arranged in a check pattern beneath the permanent magnet in such a manner that different magnetic poles are arranged alternately on the inner periphery of a hemisphere having a recessed upper portion. The direction and strength of magnetic forces of the electromagnets are controlled.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable holding device applied to, for example, a flight simulator.

0002

2. Description of the Related Art FIG. 3 is a structural diagram of a movable holding device used in a conventional flight simulator. In the figure, this movable holding device holds the flight simulator 1 on a mounting base 3 via a plurality of hydraulic cylinders 2, and by expanding and contracting the hydraulic cylinders 2, the flight simulator 1 is raised and lowered. It has become.

[Problems to be Solved by the Invention] In the conventional movable holding device as described above, the elevation angle of the flight simulator 1 held by the actual installation is limited by the length of the extension and contraction of the hydraulic cylinder 2. 1 is difficult to raise and lower over a wide range of angles. Further, due to the structure of the hydraulic cylinder 2, the flight simulator 1 cannot be rotated horizontally.

[Means for Solving the Problems] A movable holding device according to the present invention aims to solve the above problems, and is arranged in a checkerboard pattern around the bottom outer periphery of a spherical held object, and different magnetic poles are alternately arranged. A plurality of permanent magnets lined up in a row, a plurality of electromagnets arranged in a checkerboard pattern on the inner periphery of a hemisphere with a concave upper part below the permanent magnets, and with mutually different magnetic poles arranged alternately; The invention is characterized by a configuration including means for controlling.

[0005]

[Operation] That is, in the movable holding device according to the present invention, a plurality of permanent magnets are arranged in a checkerboard pattern on the outer periphery of the bottom of the spherical held body so that different magnetic poles are arranged alternately. Below the permanent magnet, a plurality of electromagnets are arranged in a grid pattern on the inner periphery of a hemisphere with a concave top so that different magnetic poles are arranged alternately, and the direction and strength of the magnetic force of these electromagnets is controlled. By appropriately controlling the direction and strength of the magnetic force of the electromagnet, the held object is elevated, elevated, and rotated while being levitated by an action similar to that of a linear motor due to the magnetic force of the electromagnet and the magnetic force of the permanent magnet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are structural diagrams of a movable holding device according to an embodiment of the present invention. In the figure, the movable holding device according to the present embodiment is used in a flight simulator for fighter jet training, and as shown in the figure, the flight simulator 11 is suspended and supported on an iron core 15 by magnetic force. There is. That is, the bottom part 12 of the flight simulator 11 has a spherical dome shape, and permanent magnets 13 are attached to the outer periphery of the bottom part 12 in a grid pattern, so that the S and N poles of the permanent magnets 13 are arranged alternately vertically and horizontally. are arranged in Further, the iron core 15 has a cage shape of a semicircular sphere, and the winding 14 is attached to the inside thereof, and the winding 14, the iron core 15, the electric wire 17 that supplies current to the winding 14,
An electromagnet is constituted by a control device 18 that controls current. These electromagnets are also arranged in a checkerboard pattern so that their S and N poles are alternately arranged vertically and horizontally. The iron core 15 is fixed on the floor by a mounting base 16. The direction and strength of the magnetic force generated from the electromagnet are controlled by the control device 18 in the winding 1.
The flight simulator 11 can be changed by controlling the current flowing through the electromagnet 4, and the flight simulator 11 is placed on this electromagnet and is raised, raised, and turned while being levitated.

In this way, this device arranges the permanent magnets 13 around the outer periphery of the hemispherical bottom 12 of the flight simulator 11 so that their S and N poles are arranged alternately, and also arranges the permanent magnets 13 inside the cage-shaped iron core 15. Attach winding 14 and transfer current to winding 1
The magnetic force generated in the iron core 15 by supplying current to the winding 14 is converted into a current by the control device 18. By appropriately controlling the magnetic force of the electromagnet and the magnetic force of the permanent magnet 13, the flight simulator 11 can be raised, raised, and turned while being levitated by the action similar to that of a linear motor due to the magnetic force of the electromagnets and the magnetic force of the permanent magnet 13. It is possible to simulate the movements of an actual fighter jet, and in particular, it is possible to train spatial awareness, which is difficult with conventional flight simulators.

[0008] If the permanent magnet 13 is attached to the entire outer circumference of the flight simulator 11, the flight simulator 11 can be raised, raised, and rotated over 360 degrees. In addition to flight simulators, this device can also be used as a driving device for leisure roller coaster simulators, spacewalk simulators, and the like.

[0009]

[Effects of the Invention] The movable holding device according to the present invention is constructed as described above, and because it levitates the object to be held by the same action as a linear motor, it can be lifted up, down, and rotated, so that the object to be held can be moved over a wider range than before. It can be tilted up and down at different angles and also rotated horizontally.
