Sectional three-dimensional model

Abstract

Disclosed herein is a sectional three-dimensional model, which can be assembled by use of an independent single type of pieces without requiring several kinds of pieces having different shapes from one another, and achieve a three-dimensional connection of the pieces. The sectional three-dimensional model includes a plurality of spherical pieces, and each spherical piece includes a pair of coupling recesses symmetrically formed in the spherical piece along a center axis of the spherical piece, and a plurality of coupling protrusions integrally formed at an outer surface of the spherical piece to be arranged in directions perpendicular to the coupling recesses, thereby allowing the plurality of spherical pieces to be connected to one another via insertion of the coupling protrusions into the coupling recesses.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a sectional three-dimensional model, and more particularly, to a sectional three-dimensional model, which can be assembled by use of an independent single shape of pieces without requiring several kinds of pieces having different shapes from one another, and achieve a three-dimensional connection of the pieces. [0003] 2. Description of the Related Art [0004] Generally, sectional three-dimensional models are assembled to have a desired shape by combining a plurality of kinds of pieces having different shapes from one another. The sectional three-dimension models are utilized mainly as educational toys for infants and children. [0005] Currently commercialized three-dimensional models, however, have a problem in that the assembling of a model requires to combine a plurality of pieces having different shapes from one another, and therefore, may be impossible when losing only a part of th...

AI Technical Summary

Benefits of technology

[0010] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a sectional three-dimensional model, which can be assembled by use of an independent single shape of pieces without requiring several kinds of pieces having different shapes from one another, and achieve a three-dimensional connection of the pieces.

[0011] It is another object of the present invention to provide a sectional three-dimensional model, which includes a plurality of spherical pieces and length-adjustable connectors for the spherical pieces, thereby achieving a free connection between straight and curved portions as well as easy regulation in distance between the spherical pieces.

[0012] It is a further object of the present invention to provide a sectional three-dimensional model, which can be assembled via the coupling of a recess and protrusion while preventing the protrusion from being inserted incompletely into the recess due to a pneumatic pressure applied into the recess.

[0013] It is yet another object of the present invention to provide a sectional three-dimensional model, which can be assembled via the coupling of a recess and protrusion without the risk of unintentional separation of the protrusion from the recess.

Problems solved by technology

Currently commercialized three-dimensional models, however, have a problem in that the assembling of a model requires to combine a plurality of pieces having different shapes from one another, and therefore, may be impossible when losing only a part of the pieces.

In particular, since the sectional models are intended to be used by infants and children lacking in the concept of proper arrangement, the models are easy to fail to fulfill their assembling function due to the loss of their constituent pieces.

Disposal of these sectional models, which are no longer useful, results in economical waste.

Another problem of conventional sectional models is in that they are assembled mainly by adopting a two-dimensional connection, and therefore, it is impossible to assemble a model having a specific shape requiring a three-dimensional connection, such as for example, a regular or rectangular hexahedral model having a corner portion.

More particularly, in the case of conventional sectional models adapted to be assembled by use of a two-dimensional connection including an X-axis and Y-axis, they have a limit to obtain a hexahedral shape including a right-angled corner portion because the corner portion requires a Z-axis perpendicular to the X-axis and Y-axis.

In conclusion, conventional sectional models are easy to fail to fulfill their functions even when losing only a part of their constituent pieces because they have a necessity for combining several kinds of pieces having different shapes from one another, and have a no ability to obtain various shapes of models including a model, which requires a three-dimensional connection, such as a hexahedron, etc., because it has only a two-dimensional connection.
