【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing the schematic structure of the present invention, FIG. 2 is a cross-sectional view for explaining the operation of the present invention when the driving unit is manual, and FIG. 3 is an explanatory plane showing the operation of this embodiment. Fig. 4, Fig. 4 is a cross-sectional view showing an embodiment in the case of using a planar moving body, and Fig. 5 is a cross-sectional view using a planar outer shell and a curved moving body that makes point contact therewith. is there.

According to the present invention, a planar or curved moving body that makes point contact with an outer surface of a curved or flat outer shell is mounted, and a magnetic body provided in the outer shell is moved along its inner wall. It is characterized in that it gives a moving body an entertaining motion. Although the means for moving the magnetic body may be manual, this embodiment describes the case where an electric power or elastic force restoring drive body is used. Of course, the structure of the driving unit is not a special one, and a known technique is used. The structure and appearance of the outer shell and the moving body may be arbitrary. For example, a "sunflower" -shaped flower shape is adopted as the outer shell, and the moving body is shaped like a butterfly playing with a flower shape. Things are adopted.

As shown in FIG. 1, the freely movable structure 1 of the present embodiment includes a hemispherical outer shell body 2, a magnetic body 3 arranged close to the inner wall of the outer shell body 2, and a rotating magnetic body 3. Further, it is composed of a driving unit 4 which is movably driven, and a curved moving body 5 which is mounted on the outer surface of the outer shell body 2 and has a magnetic force absorber 6 therein. The magnetic substance 3 and the magnetic force absorber 6 are magnetically coupled to each other.

The structure of the drive unit 4 may be arbitrary, but the illustrated one is adopted for convenience of description. That is, the rotary plate 10 is connected to the rotary shaft 8 connected to the power source 7 via the switch 9. A plurality of magnetic bodies 3 are fixed to the outer periphery of the rotary plate 10. The magnetic body 10 has the N pole side arranged on the inner wall side of the outer shell 2. Further, the magnetic force absorber 6 of the moving body 5 has the S pole side arranged on the outer shell body 2 side. As the power source 7, for example, a motor is used. When the moving body 5 is placed on the outer shell body 2, the magnetic body 3 and the magnetic force absorbing body 6 attract each other, the switch 9 is turned on, and the motor rotates.

FIG. 2 shows a case where a manual drive unit is used. By moving the magnetic body 3 in any direction along the inner wall of the outer shell 3 by inserting the hand 11 from the inside of the outer shell 2, it is possible to give the moving body 5 a desired movement form.

FIG. 3 shows the operation of this embodiment. When the magnetic body 3 shown by the dotted line is moved in the direction of arrow F, an attractive force acts on the magnetic force absorber 6. Since the moving body 5 to which the magnetic force absorber 6 is fixed is in point contact with the outer shell body 3 at the point C, the moving body 5 is held in a state in which it can be easily rotated. On the other hand, even if the attraction forces acting on the target points A and B around the point C are the same, the frictional resistances of those portions often differ. Therefore, the moving body 5 rotates around the point C. By changing the moving direction of the magnetic body 3 in various ways, the moving body 5 can be moved in an entertaining manner.

FIG. 4 shows an embodiment in which a planar moving body 5a is used instead of the moving body 5 shown in FIG. In the figure, the same reference numerals as those in FIG. 1 are the same, and the description thereof will be omitted. Even in this case, since the outer shell 2 and the moving body 5a are in point contact with each other, the moving body 5a behaves in an interesting manner as in the above embodiment.

FIG. 5 shows an embodiment in which a curved moving body 5 is mounted on a flat outer shell body 2a. In this case as well, since both are in point contact, the same operation as in the above embodiment can be performed.

In the above embodiments, electric power such as a motor was used as the power source, but a non-power elastic force recovery driver such as “spring” may be used. In this case, as shown in FIG. 1, it is necessary to attach the mainspring winding knob 12. Further, the shapes of the magnetic body 3 and the magnetic force absorber 6 are not specified, but a cylindrical shape is desirable in order to move the moving bodies 5 and 5a in a more entertaining form. Further, the switch is not limited to one by magnetically coupling the magnetic body 3 and the magnetic force absorber 5, but may be one that reacts to sound or light, for example.

Various shapes are used as the outer shell bodies 2 and 2a and the moving bodies 5 and 5a. As described above, for example, the outer shell body 2 is formed of a "sunflower" shape, and By forming 5 from butterflies playing with it, it is possible to express the situation in which the butterflies dance around the sunflowers. Alternatively, the outer shell 2a may be grounded, and the moving body 5 can be likened to a soccer ball. Furthermore, by forming the moving body 5 from a ballerina doll, it is possible to express the form in which the ballerina dances around on the stage. From the above, various interesting forms can be expressed.

[Effect of device]

 According to the present invention, the following remarkable effects are obtained. 1) Mount a moving body on the outer surface of a curved or flat outer shell, and move the magnetic body along the inner wall of the outer shell while magnetically coupling the magnetic body inside the outer shell with the magnetic absorber of the moving body. By adopting the structure, it is possible to give rotation and arbitrary movement to the moving body. 2) It is possible to express interesting movement by devising the movement of the moving body. 3) Since the moving body is magnetically coupled to the outer shell side, it can be enjoyed for a long time without falling. 4) The circuit is switched on by the magnetic coupling between the magnetic substance and the magnetic absorber, so no special switch mechanism is required, the structure is simple, and anyone can enjoy it. 5) It is possible to contribute to resource saving and environmental protection by using an elastic force recovery driver as a power source. 6) Since the magnetic body and the drive unit are housed in the outer shell, the overall structure is made compact.
