Description

[Detailed description of the invention] [Field of industrial application] The present invention consists of a large-diameter sphere made of a sponge body that is compressible and expandable, and several small-diameter spheres that are also made of a sponge body that also has compressibility and expandability. Concerning a magic tool consisting of.

[Conventional technology]

Traditionally, magic tools using sponge bodies include:
For example, JP-A-49-102446 proposes a magic ball that consists of a plurality of magic ball bodies made of an elastic material and a hemispherical cap that fits into the ball bodies.

Further, as shown in FIG. 7, the urethane foam is die-cut into various animals 10 or predetermined shapes, and a bottomed hole 12 of a predetermined size is cut out in the center of the bottom surface 11 of the die-cut animal 10. Japanese Utility Model Application Publication No. 140600/1982 discloses a magic tool 14 which is constructed by molding a mascot tip, and turning over the hole cut out in the bottom of the mascot tip 10 to reduce and deform it into a spherical body 13 as shown in FIG. has been proposed.

[Problem that the invention attempts to solve]

However, the magic ball disclosed in JP-A-49-102446 has multiple ball bodies of the same diameter,
Since it is used for magic tricks to increase or decrease the number of balls by combining it with a hemispherical cap, there is a problem that there is little variation, and it requires skill because it is performed by holding the ball between the fingers. There was a problem with that.

On the other hand, the magic tool 14 described in the above-mentioned Japanese Utility Model Publication No. 53-140600 has a hole 12 with a bottom in the bottom surface 11 of the mascot tip 10, and a spherical body 13 is formed by turning the mascot tip 10 made of urethane foam over. The bottomed hole 12 is a hemispherical part 1 at the tip with a relatively small diameter.
5 and a cylindrical portion 16 having the same inner diameter as the hemispherical portion 15.
Since the top of the mascot tip 10 is held down, it can be easily turned over.Once the entire mascot tip 10 is squeezed and contracted, the end portion 17 of the bottomed hole 12 is held and the tip is widened. Since it is necessary to recreate it and the operation is complicated,
The problem was that it was difficult to do it in a short period of time.

Of course, if the diameters of the hemispherical part 15 and the cylindrical part 16, which have the same diameter, which constitute the bottomed hole 12 are increased, the mascot 10 can be easily turned over, but in this case, the Bottomed hole 1
Since the diameter of the end portion 17 of the spherical body 13 is large, and the surfaces of the hemispherical portion 15 and the cylindrical portion 16 that tighten the spherical body 13 are wide, there is a problem that the surface of the folded object becomes uneven and does not become spherical. The dot was hot.

Moreover, since the inside of the bottomed hole 12 is straight, it is difficult to insert several small balls without exposing some of them, and it is not possible to use them for magic tricks that involve combining multiple balls. The problem was that it was difficult.

The present invention was developed in view of these circumstances, and it can be easily turned over in a short period of time suitable for performing magic tricks, and furthermore, the turned over shape is approximately spherical, and moreover, it is a sphere that has become spherical. To provide a magic tool capable of storing several spheres having approximately the same diameter inside and appearing to be able to change the size of the spheres when viewed from the outside.

[Means to solve problems]

A magic tool according to the present invention that meets the above purpose is a magic tool consisting of a large-diameter sphere made of a sponge body having compressibility and expandability, and several small-diameter balls made of a sponge body also having compressibility and expandability. The large-diameter sphere is provided with a small circular hole consisting of a short tube portion and a spherical portion having an inner diameter sufficiently larger than the diameter of the short tube portion, and the outside of the large-diameter sphere is pushed to open the small circular hole. When the large-diameter sphere is made into an inverted small-diameter sphere by exposing the hole to the outer surface, the diameter of the inverted small-diameter sphere is approximately equal to the diameter of the small-diameter sphere.

[Effect]

The magic tool according to the present invention consists of a large-diameter sphere made of a compressible and expandable sponge body and several small-diameter spheres, and the large-diameter sphere has a small circular hole consisting of a short tube part and a spherical part. is provided, and the diameter of the spherical part is sufficiently larger than the diameter of the short pipe part, so that the small circular hole slightly widens the inlet end, and the small circular hole of the large-diameter sphere is formed, forming a part. By pushing the surface of the large-diameter sphere on the opposite side toward the small circular hole, it can easily be turned over to become an inverted small-diameter sphere.

Since the end of the small circular hole that is turned back is sufficiently smaller than the diameter of the spherical part, when it is turned back, the end becomes smaller and becomes closer to a sphere.

Moreover, since a small circular hole that is enlarged from the entrance of the large diameter ball is formed inside the large diameter ball, several small diameter balls can be stored without difficulty, and when stored, the small diameter balls are difficult to see from the outside.

Since the diameter of the inner spherical part of the large-diameter ball is sufficiently small, it can be turned over to form an inverted small-diameter ball, and the diameter of the inverted small-diameter ball is approximately equal to that of the small-diameter ball. This makes it difficult to distinguish between them, which allows them to be used for magic tricks that change the diameter.

〔Example〕

Next, an embodiment embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention.

Here, FIG. 1 is a side sectional view of a large-diameter sphere constituting a magic tool according to an embodiment of the present invention, FIG. 2 is a plan view of a small-diameter sphere forming the magic tool, and FIG. FIG. 4 is a front view of the large-diameter ball turned over; FIG. 5 is a side view of the large-diameter ball with a small-diameter ball housed in it;
FIG. 6 is a side view showing the state in which the magic tool is used.

As shown in FIG. 1, a large-diameter ball 20 constituting a magic tool according to an embodiment of the present invention is made of a compressible and expandable sponge body, and has a small circular hole 21 at one location on its circumferential surface. is formed.

This small circular hole 21 has a short pipe section 22 connected to the outside.
and a spherical part 23 which is connected to the short tube part 22 and has an inner diameter sufficiently larger than the diameter of the short tube part 22, and the inlet end 21a of the small circular hole 21 is widened to form the top of the large diameter sphere 20. By pushing 24 over, it is inverted so that the small circular hole 21 is on the outside, forming an inverted small diameter sphere 25 as shown in FIG. This inverted small diameter ball 25 is the fourth
As shown in the figure, when viewed from the front, the end 21a of the small circular hole 21 is not visible and has a spherical shape.

FIG. 2 shows several (three in the embodiment) small diameter balls 26, 27, 28 that are paired with the large diameter ball 20.
, whose diameter is the inverted small diameter sphere 25 shown in Fig. 4.
are almost equal.

FIG. 5 shows a state in which the small diameter balls 26, 27, 28 are inserted into the small circular hole 21 of the large diameter ball 20.
is made of a sponge body, so the small circular hole 21
The small diameter balls 26, 27, and 28 can be easily inserted into the inside of the large diameter ball 20, and the shape and size of the large diameter ball 20 as a whole will not change even if the small diameter balls 26, 27, and 28 are inserted.

Since the entrance of the small circular hole 21 is smaller than the diameter of the small diameter balls 26, 27, and 28 inserted, even if the large diameter ball 20 is rubbed, the small diameter balls 26, 27, and 2
8 will not be exposed.

Next, the large diameter ball 20 and the small diameter balls 26, 27,
Regarding how to use the magic tool consisting of 28 pieces,
To explain with reference to FIG. 6, first, in the state of A, the large diameter ball 20 is turned over and the inverted small diameter ball 20 is turned over.
When lined up with the other small diameter balls 26, 27, and 28, it appears that there are four small diameter balls.

Next, the small-diameter balls 26, 27, and 28 are made smaller by hand and pressed against the inverted small-diameter ball 25.
When Step 5 is turned over, the small diameter balls 26, 27, and 28 fit inside the small circular hole 21 to form one large diameter ball, as shown in Fig. 5, but the four small diameter balls are combined. It looks as if it has become one large-diameter sphere (as shown in Figure 6B).

Next, from the inside of this large diameter ball 20, the small diameter ball 2 is
When you pick out the ball 8, it immediately becomes spherical, so the large diameter ball 2
It appears that a small diameter sphere 28 was born from 0 (6th
(Illustrated in Figure C). By repeating this state, the three small diameter balls 26, 27, 28 contained inside can be taken out, and the three small diameter balls 26, 27, 2 from the large diameter ball 20.
8 appears to have been born (as shown in Figure 6D).

Further, by changing the state from D to C and B shown in FIG. 6, it appears that the large diameter ball 20 absorbs the small diameter ball, and the play is free.

[Effect of idea]

As is clear from the above description, the magic tool according to the present invention has a large diameter sphere made of a compressible and expandable sponge body, and several small diameter spheres also made of a compressible and expandable sponge body. Since the large diameter ball is provided with a small circular hole consisting of a short tube part and a spherical part having an inner diameter sufficiently larger than the diameter of the short tube part, the outside of the large diameter ball can be pushed. It is easy to repeat the ball once, so even beginners can perform the magic trick of changing the diameter of the ball in a short time.

In addition, the small circular hole has a spherical part with a larger diameter than the short pipe part at the entrance, so more small diameter balls can be stored inside, and the diameter of the short pipe part at the entrance is slightly smaller. Because it is curved, it is difficult to see what is stored inside, and there is no risk of the small diameter balls inside spilling out during kneading.

Furthermore, since the diameter of the inverted small-diameter sphere, which is obtained by inverting the large-diameter sphere, is approximately equal to the diameter of the other small-diameter sphere,
It becomes difficult to distinguish between inverted small diameter balls and small diameter balls,
With this, it is possible to easily perform the magic trick of combining small diameter balls of the same diameter to form a large diameter ball.
