Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a magnetic rotating toy in which rotating blades are rotated in a transparent hollow sphere by attraction and repulsion of magnets.

[Conventional technology]

Conventionally, the magnetic rotating toy as described above has never existed.

[Problems to be solved by the device]

The purpose of this invention is to hold the transparent hollow sphere with one hand and hold the magnet holder with the other hand to bring the magnet holder close to the magnet shaft support of the hollow sphere, Provide a highly attractive magnet rotating toy with a novel configuration that does not exist in the past, in which the rotating blades are configured to rotate within a hollow sphere by the magnetic attraction / repulsion of the magnets when manually operated to rotate. To do.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the magnetic rotating toy according to the present invention comprises two upper and lower hemispherical bowl-shaped bodies made of transparent synthetic resin.
Hollow sphere 3 constructed by joining 1 and 2 that can be held with one hand
A rotary shaft 4 supported so as to rotate around a horizontal axis at the inner center of the hollow sphere 3 and a central slit groove 4a long in the axial direction of the rotary shaft 4 so as to extend in the radial direction of the sphere. And a plate-shaped rotary blade 5 inserted into and fixed to the outer peripheral wall of the rotary shaft 4 whose semicircular portion surrounded by a half circumference is magnetized by N pole and the semicircular portion surrounded by the remaining half circumference is magnetized by S pole. A magnet holder that holds a ring-shaped permanent magnet body 6 fitted to one end and a disk-shaped permanent magnet body 7 magnetized with S and N poles in the thickness direction and that can be held by the other finger. 8 is provided.

[Action]

The magnet rotating toy having the above-described configuration is used by holding the hollow sphere 3 with one hand and holding the magnet holder 8 with the other finger. The magnet holder 8 is brought close to the magnet shaft support portion of the hollow sphere 3, 2nd to rotate around the axis of the magnet shaft support
When manually operated as shown in the figure, the magnetic attraction of the magnet bodies 6 and 7
The repulsive action causes the rotary blade 5 to rotate integrally with the rotary shaft 4 inside the hollow sphere 3.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In the figure
Reference numerals 1 and 2 denote two upper and lower hemispherical bowl-shaped bodies formed of a transparent synthetic resin. By joining the two hemispherical bowl-shaped bodies 1 and 2 by edge fitting and joining, one hand (for example, left hand) A hollow sphere 3 having a diameter of about 10 cm and which can be seen through is formed.

Reference numeral 4 denotes a rotary shaft that is supported at the inner center of the hollow sphere 3 so as to rotate about a horizontal axis. The rotary shaft 4 has a central slit groove 4a that is long in the axial direction, and Both end shafts are inserted into and engaged with U-shaped bearing holes 3a, 3b formed at the joint with the upper bowl-shaped body 1 so as to be rotatably supported.

Reference numeral 5 denotes a plate-shaped rotary blade that is inserted and fixed in the central slit groove 4a of the rotary shaft 4 so as to extend in the radial direction of the sphere. The rotary blade 5 is, for example, a bird on the front surface of the one side extending plate portion 5a. A picture B is printed and formed on a cardboard with the picture A of the birdcage printed on the rear surface of the extension plate portion 5b on the other side. A bird is present in the birdcage due to a visual afterimage phenomenon when the rotary blade 5 rotates. A picture like this (Fig. 2 clearly) can be seen. Reference numeral 6 denotes a ring-shaped permanent magnet body having a central angle hole fitted and fixed to one end portion, for example, the right end angle shaft portion, of the rotary shaft 4 which approaches the spherical outer wall, and the ring-shaped permanent magnet body 6 is surrounded by a half circumference. The semicircle part that is drawn is N
It is magnetized in two so that the semi-circular portion which becomes the pole and is surrounded by the remaining half circumference becomes the S pole. Reference numeral 7 denotes a disk-shaped permanent magnet body in which the S pole and the N pole are magnetized in the thickness direction.
Is held in the circular recess 8a of the magnet holder 8 that can be held by the other finger (for example, the right finger) so as not to come off.

Then, the magnet holder 8 is brought close to the magnet shaft supporting portion of the hollow sphere 3 as shown in FIG.
When the rotating operation is performed as shown by, the magnet bodies 6, 7
The magnetic attraction and repulsion of the rotary blade 5 causes the rotary blade 5 to rotate integrally with the rotary shaft 4, and when the rotary blade 5 rotates, it is possible that a bird is present in the bird cage due to a visual afterimage phenomenon of human beings. You can see the picture.

[Effect of device]

Since the magnet rotating toy of the present invention has the above-mentioned configuration, the transparent hollow sphere 3 is held by one hand and the magnet holder 8 is held by the other finger, and the magnet holder 8 is held by the hollow sphere. By bringing the magnet 3 closer to the magnet shaft support and manually operating the magnet so as to rotate around its axis, there is an effect that the rotary blade 5 can be rotated in the hollow sphere 3 in an interesting manner, which is not existing in the past. It is possible to provide a magnet rotating toy having a highly interesting structure.
