DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a toy that looks inside through a viewing hole provided in a box-shaped hollow body and pseudo-stereoscopically views an image formed in an internal space.

[0002]

2. Description of the Related Art Conventionally, as a toy for pseudo-stereoscopically viewing an image formed in an internal space through a peephole provided in a box-shaped hollow body, two eyes are aligned with two peepholes. In some cases, it was possible to see a three-dimensional image by looking inside with both eyes. In this case, the image for stereoscopic viewing may include two images for the left and right eyes and another image for the left and right eyes by viewing one image from different angles depending on the left and right eyes. There is a structure in which minute irregularities are formed so that the image can be seen, and a so-called 3D art drawn by a computer graphic method.

[0003]

However, in the above-mentioned conventional devices, it is necessary to look through both eyes to obtain a three-dimensional effect, and two viewing holes are also required. In addition, there is a problem that fresh surprise is not felt because it is widely known in various forms.

Accordingly, an object of the present invention is to provide a pseudo-stereoscopic toy that allows a user to experience a feeling as if a three-dimensional stereoscopic image is being generated in the internal space of a small hollow body, even though the viewer looks in one eye. It was done as.

[0005]

According to a first aspect of the present invention, there is provided a pseudo-stereoscopic toy according to the present invention, wherein a peeping hole is formed in a shell of a hollow body formed of a translucent material, for peeking into the interior. A sheet body or a three-dimensional body is arranged in the internal space of the hollow body, and an image is formed on a surface of the sheet body or the three-dimensional body that can be seen through the viewing hole.

According to a second aspect of the present invention, the hollow body of the first aspect is a cube, and the solid arranged in the internal space has four vertices within four vertices which are not adjacent to each other among the eight vertices of the cube. It is an equilateral triangular pyramid.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pseudo stereoscopic toy according to the present invention will be described below in detail with reference to the drawings showing an embodiment.

Reference numeral 1 denotes a cube formed of a translucent material such as paper or a resin sheet. Reference numeral 2 denotes a viewing hole provided at one vertex of the cube 1. Numeral 3 denotes a regular tetrahedron (regular triangular pyramid) arranged in the internal space of the cube 1, and its four vertices 3
A, 3B, 3C and 3D are inscribed in four vertices 1A, 1B, 1C and 1D which are not adjacent to each other among the eight vertices of the cube 1. That is, three vertices 3A, 3B,
The plane P including 3C is arranged at a position where the plane P can be viewed through the viewing hole 2.

The length of one side of the regular tetrahedron 3 is set slightly shorter than the length of a diagonal line of one surface of the cube 1.

Reference numeral 21 denotes a viewing hole provided at another vertex of the cube 1, and three vertex 3 A, 3 of the regular tetrahedron 3.
It is possible to look into the surface Q including B and 3D. The plane R including the three vertices 3A, 3C, and 3D of the regular tetrahedron 3 can be viewed from another viewing hole 22. Further, although not shown because it is on the back side of the cube 1, a viewing hole through which the remaining surface of the regular tetrahedron 3 can be seen is provided on the back side.

[0011] In this way, from the observation holes 2, 21, 22, ... provided at the four vertices of the cube 1, the positive 4
It is configured such that the four faces P, Q, R,... Of the face body 3 can be respectively viewed.

The four faces P, Q, R,... Of the regular tetrahedron 3
Are attached or printed with photos S,... Of different scenes. If a convex lens is attached to the viewing hole, the surface of the regular tetrahedron 3 moves away due to refraction of light, so that an effect that the eyes are easily focused can be obtained. Further, even a fine image can be seen in detail. This lens may be detachably attached.

When the user holds the pseudo-stereoscopic toy 1 having such a structure in his / her hand and looks through the viewing hole 2 with one eye, a photograph S of one surface P of the regular tetrahedron 3 arranged inside can be seen. Since the cube 1 is formed of a translucent material, the surface P is brightly illuminated and is easy to see. At this time, a pseudo three-dimensional sensation can be obtained as if the user were looking at a stereoscopic image with both eyes, even though they were looking through with one eye.

By drawing a series of pictures or images with a story on each side of the regular tetrahedron 3,
Since each of the four different scenes can be viewed with a pseudo three-dimensional sense, strong curiosity can be invited, and an effect that has not been achieved as a pseudo stereoscopic toy can be obtained.

As shown in FIG. 2, a sheet, a polyhedron or a sphere may be arranged inside a triangular pyramid or a spherical hollow body. In the case of a sheet, an image may be drawn on the two surfaces on the front and back, and the image may be viewed through two corresponding viewing holes. In the case of a polyhedron, different images can be drawn on each surface, and corresponding viewing holes can be provided for viewing.

In the case of a spherical body, a picture or an image by a computer graphic technique is drawn on the spherical surface, so that it can be seen through a peephole provided in the hollow body. As the image, various images such as a picture, a figure, a photograph, and an image by a computer graphic technique can be adopted. In addition, as a drawing method, printing, handwriting, a method of applying a photosensitive material and directly sensitizing, an electrophotographic copying, etc.
Various methods can be employed.

Although the pseudo-stereoscopic toy of the present invention can provide various educational effects as described above even in a completed state, a pseudo-stereoscopic toy that can obtain the above-mentioned effects can be obtained by using an assembled kit. The pleasure of completing it with your own hands is also obtained. If you want a prefabricated kit,
What is necessary is just to distribute the sheet material in which the development view of each of the hollow body and the internal triangular pyramid is illustrated, and the assembly instruction thereof.

[0018]

According to the first aspect of the present invention, when an image drawn on an inner sheet or a three-dimensional surface through a peephole provided in a hollow body with one eye, the image becomes pseudo-three-dimensional. Because they can be seen with sensation, they can be interested in the illusion of human vision and how to perceive a space by visual perception, etc., and can cause scientific curiosity. Thus, according to the pseudo stereoscopic toy of the present invention, an educational effect or a scientific enlightenment effect can be obtained.

According to the second aspect of the present invention, a triangular pyramid whose four vertices are inscribed in four vertices which are not adjacent to each other among the eight vertices of the cube is arranged in the internal space of the hollow cube. By looking at the four images drawn on the four sides of the triangular pyramid from the four viewing holes provided at the corresponding positions, different pseudo three-dimensional images can be seen.
