DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a spatial logical plaything for developing stereoscopic vision and having a parallelepipedon-like shape, comprising movable elements of similar form filling up the available space inside, but leaving a volume non-occupied corresponding to the volume of a movable element. Said movable elements do not displace on the effect of their own weight.
The invention relates furthermore to a coupling structure for joining flexible plates angularly especially lattice side plates of said spatial logical plaything according to the invention.
PRIOR ART
There are known a lot of logical playthings comprising elements displaceable in a rectangular parallelepipedon formed space surrounded by frames or lattice plates, and the number of the elements is one piece less then the elements having room in the available space. By utilizing this single non occupied blank room it is possible to move the elements distinguished by symbols, colours for realizing a possible configuration, which is the end purpose of the play.
Such kind of plaything is described for example by the U.S. Pat. No. 3,845,959, furthermore the DE-PS 2,152,360 and finally the U.S. Pat. No. 4,036,503. The characterizing features of these prior art playthings are as follows:
The essence of the patent specification U.S. Pat. No. 3,845,959 is a closed, expediently cubical external case, wherein a central block with similar formation is located in the space bordered by six perpendicular side plates, and each surface of said central block is in equal distance from the relating side of the case. In the free area between the case and the central block movable blocks are found, the numbers of which are one piece less then the blocks having room in the available space, their shape is similar to the external case, their one or more surfaces can be distinguished from the central block. The openings on the sides of the case make possible to displace said movable blocks, and by selectively transferring them a particular interrelation or arrangement can be achieved, which means the realization of the task to be solved.
The characteristic of the plaything according to DE-PS 2,152,360 is in that in one frame--which expediently borders cubical space--similarly shaped geometrical bodies are arranged, the edge length of the frame is n-fold of the edge length (n=2, 3, . . . ) of the geometrical bodies, which can be moved in three directions parallel with the edge length of the frame, and in the frame n.sup.3 -1 pieces geometrical bodies are arranged. The object of the logical plaything is similarly the same as that of the previous plaything, i.e. the cubical geometrical bodies distinguished by symbols to each other should be arranged according to a pattern meeting the requirements of the task to be realized and predetermined in advance.
The patent specification U.S. Pat. No. 4,036,503 describes a manipulative logical plaything, comprising a case having perpendicular parallelepipedon formed transparent back- and front plates, the side plates of which are narrower than the front- and back plate, said casing comprises regular polyhedrons with similar form and arranged in a certain number columns next to each other. The number of the polyhedrons is one piece less than the number of polyhedrons which would have room in the available space of the case, whereby one column contains one polyhedron less than the other columns.
The width of the side plate and the height of the case are a little bit larger than the peak distance of the polyhedron, respectively the height of the highest column, whereby there is a possibility to rotate at least one polyhedron around its vertical center line by means of careful manipulation of the case as well as by means of horizontal torsion of the case, and it is also possible to turn to the lower column supporting on the lower edge of the polyhedron being on the top of the higher column.
These moving methods make possible to arrange the polyhedrons--expediently cubes--distinguisbed with symbols to provide a pre
