Spatiol Logical Toy
Technical field
The invention relates to a spatial logical toy consisting of solids having been mutually fixed in such a manner, as to be rotated relative to one another; the solids exposing the single parts of the playsurface are adapted to rotate in groups around the axis having been arranged in the geometrical centre of the playsurface(s) and lying oerpendicularly to the same; the solids can be arranged and rearranged, while the axes of rotation of the groups of solids forming the playsυrface(s) of the toy are intersecting one another in a single point .
Background art
A spatial logical toy of this type has been described in the Hungarian Patent KU-P5 170 062. With this solution eight or twentyseven solids are assembled to form a closed cubiform or spherical surface, expediently a sphere, which are engaged with' further connecting elements . With the cube having been assembled of twentyseven solids - serving as an example - the solids on the corners are formed so, as to contain also the external surface-parts of a spherical surface, while the elements lying in the edge-centres and in the face-centres are formed with the internal surface-parts of a sphere of the same radius, accordingly, when properly fitted, they can be rotated on one another. In order to ensure structural integrity of the large cube, i. e. to prevent disassembly, the solids being arranged in the face-centres, are elastically fixed to a small cube being arranged in the middle of the large cube but without restriction of rotational freedom around their own axes .
With this solution , however, the internal spherical ports formed on the single solids do not form an organic integrity but the sp here can be assembled of the parts having been arranged
on the single solids. Essentially, the solids are interconnected by fitting the spherical surfacial parts into and to each other, respectively.
A further problem is involved in establishing patterns of a different composition by means of the solution according to the cited patent, so e. g. in case of eight solids forming the outer surfacial parts, further eighteen connecting elements are needed resulting in an utmost complicated structure.
Disclosure of Invention The invention is based on the recognition that in case, if the spherical surface is made of one single piece and the solids are fixed to said spherical surface by means of extensions protruding into and being slideable in the channels having been formed on the spherical surface resp. on the solids and which are engaged with the solids i. e. with the spherical surface by means of pins or between the spherical surface and the solids the adhesive engagement is provided by magnetic means, the formation of several kinds of spatial logical toys becomes possible in a considerably easier manner, than with the known solutions. Consequently, in accordance with the invention the solids are in engagement with a single_piece spherical surface, whereby the centre of the spherical surface is arranged in the point of intersection of the axes of rotation of the groups of solids forming the playsurface(s), In the present specification under a "one-piece spherical surface" a surface is meant, the area of which is provided with channels or the surface is formed with perforations, gaps, intermissions, holes or any other discontinuities; as a consequence, the surfacial parts may restrict to surfacial points, furtheron, to a part of the surface other bodies may be attached or a certain cart or parts of the spherical surface may be formed as an integer part of other surfaces, however, the remanent surfacial parts or points,
which cannot be displaced in relation to one another, are forming a spherical surface.

Best Mode of Carrying out the Invention
With the embodiment according to figure 1, between eight solids 1 appearing as a cube seen from outside (out of which for graphictechnical reasons only four have been illustrated without the interconnections inbetween), an internal one-piece spherical surface 2 is arranged. Essentially, the solids 1 are of cubiform, with a cut-out cavity needed for the spherical surface 2. One of the solids 1 is formed so, as to form an integral entirety with the spherical surface 2, with other words, it forms a one-piece unit therewith. All the other solids 1 are formed inside with the surfacial part 3 of the sphere, the radius of which corresponds to the radius of the spherical surface 2. One of the faces each
of the large cube 4 having been assembled of the eight solids 1 is forming the playsurface 6 consisting of the quadratic surfacial parts 5 comprising four Faces each of the solids 1. In the face-centre of the quadratic playsurface 6, the four faces each of the solids 1 belonging to the playsurface 6 may be rotated around the axes lying perpendicularly to the playsurfaces 6. Said axes of rotation are intersecting each other in the centre of the large cube 4, while said centre is simultaneously forming the centre of the spherical surface 2 and the surfacial parts 3 of the sphere, respectively.
Dissimilarly to the embodiment to be seen in Fig. 1, the large cube 4 can be assembled of twentysix of fiftysix solids 1, as well as of a spherical surface 2 of the corresponding size. In the former case there are nine, in the latter one .sixteen surfacial parts 5 on the single faces; the group 7 of solids, formed of the nine and sixteen solids 1, respectively, belonging thereto, may be rotated by turning-off the playsurfaces 6 around the normals passing through the contre. of the large cube 4. In this case it seems to be expedient to form the eight solids 1 en the corners so, as to form an integral entirety, i. e. a monolithic (one-piece) unit with the spherical surface 2 (Fig. 2). The assembly of the large cube 4 of ninetyeight solids 1 becomes also possible. In this case there are twentyfive surfacial parts 5 arranged on the single faces and twentyfive of the solids 1 will form a group 7 of solids. With this solution the solids 1 are of different geometrical shape (cube, prism) in the single groups.
The solids 1 contained in the large cube 4 may be formed in such a manner too, that they do not show a cubiform, when seen from the outside. 5o e. g. the large cube 4 can be cut along the plane of the diagonals of two opposed sides lying perpendicularly to one another, in this case sixteen solids 1 will be obtained (Fig. 3).
According to another solution, the large cube 4 is divided into sixteen parts by the planes running parallel with two parallel
faces of the large cube 4. Each group which shares one face of the assembly is expediently rotated by 130 in both cases, however, as a rotation by 90 is also possible, the play is rendered even more complicated (Fig. 4). It goes without saying that other modes of divisions are also possible, depending on the engagement of the solids 1 with the spherical surface 2.
Between the solids 1 and the spherical surface 2 engagement may be provided by magnetic means. In this case the shell of the spherical surfacial parts 3 are provided with the magnetic pole-pair(s) c ensuring adhesion, while the magnetic lines of force are closed through the shell of the spherical surfacial parts 3 having been made of soft magnetic material. The Fig. 5 is showing the section of such a solution. The magnetic pole-pair S consists of the magnetic dipole 9, the axis of which is running parallel with the tangent-plane of the spherical surfacial part 3 of the sphere, belonging to the given place and of the soft-iron armatures 10 each connected to the two poles of the dipole 9 and arranged perpendicularly to the tangent-plane of the spherical surfacial part 3 of the sphere, belonging to a given place. In case of a magnetic engagement it is not essential to assemble the spherical surface 2 with some solid 1.
The engagement between the solids 1 and the spherical surface 2 may be established by mechanical means. In this case on the spherical surface surface 2 there are the channels 12 forming a closed curve with a circular generatrix, i. e. the pitch circle 11, penetrating towards the centre of the spherical surface 2; in said channels 12 the extensions 14 are outstanding from the spherical surfacial parts 3 being connected to the spherical surfacial parts 3 by means of the pins 13. The width of the extensions 14 is dimensioned in compliance with the width of the channel 12, as to be able to slide them in the
channels 12. At the same time, the openings 15 (groove-orifices) of the channels 12 are formed in such a manner, that outside of the extensions 14 could be prevented, but without the restriction of the movement of the pins 13, the width of which is less, than the width of the extensions 14. The arrangement of the channels 12 is to be seen in Fig. 6 illustrating the section of the large cube 4 consisting of eight solids 1, taken through one of the planes of rotation.
In the channels 12, between the extensions 14, there are either the distance-pieces 16 or the spring elements 17
- ensuring the arrested position of the extensions 14 - arranged. A solution of this kind is to be seen in Fig. 7.
The planes of the pitch circles 11 of the channels 12 are running parallel with the plane of rotation of the groups 7 of solids. Accordingly, if the single groups 7 of solids are rotated along the planes running parallel with the six faces of the large cube 4, the pitch circles 11 will be arranged on the spherical surface 2 in three planes or in a set of planes (Fig. 8). If the large cube 4 is assembled of eight solids 1 and one of the solids is connected with the spherical surface 2 in an immovable manner, three channels 12 with pitch circles 11 in planes lying perpendicularly to each other, intersecting one another on totally four places, are sufficient (Fig. 9).
In Fig. 10 the section of a solid 1 is to be seen, with which the extension 14 is rigidly fixed to the solid 1 by means of the pin 13. With a preferred embodiment of the invention the extension 14 is provided with a spring 10, accordingly, the solid 1 is elastically engaged with the spherical surface 2, as it is to be seen in Fig. 11. With a further preferred embodiment the extension 14 is rigidly connected with the solid 1, though with the difference, that the solid 1 and the spherical surfacial part 3 of the sphere are separated by means of a compression spring 19, as it is to be seen in Fig. 12.
In case of the circular channels 12 intersecting each other, the most advantageous solution may be obtained with normal intersections; accordingly, in cases, when intersections are not always the normal ones - e. g. the solution having been illustrated in Fig. 3 - it seems to be more expedient to use the magnetic engagement. Besides, the engagement with magnetic means involves the considerable advantage, in so far as, while playing, the large cube 4 does not come to pieces, on the other hand, when out of game, it can be disassembled and assembled in an optional combination and from the basic position thus obtained, the game can be started again. In such a manner situations similar to chess problems may be established, where the object of manipulation is to produce another predetermined combination by transformations (steps) of predetermined number.
Each surfacial part 5 may have patterned or coloured surface (individually or in groups) and the task lies in e. g. to restore the playsurface 6 consisting of surfacial parts 5 of the same colour. The solid 1 may be formed so, that instead of one extension 14 according to Fig. 10 three extensions 14 are arranged on the solid 1, at the meeting point of the spherical surfacial part 3 of the sphere and the planar surfaces of the solids 1 being slideable on one another. In this case the extension 14 occupies only the half of the channel 12, the other half of the channel 12 is occupied by the similarly shaped extension 14 of the adjacent solid 1; such an embodiment - having been provided with the channels formed in the previously described manner - is to be seen in Fig. 13, while the view of a solid 1 being slideable in the channels 12 in Fig. 13, is illustrated in Fig. 14.
The spherical surface 2 may be arranged not only inside the solids 1 but also outside the solids 1. In this case the outer surface of the solids 1 is preferably formed as a sphere;
the spherical surface 2 is provided with the openings 20; reaching in with the hand in said openings 20, the solids 1 can be turned-off. The inside of the solids 1 may be optionally shaped and can be provided with lightenings, the only requirement lies in that the solids 1 could properly slide on one another. Preferably, one of the solids 1 is formed as a single piece with the outer spherical surface 2 or at least it should be fixed rigidly to the same. The outer spherical surface 2 is made of a transparent material (see Fig. 15). According to another embodiment of the invention on the outer spherical surfacial part 3 of the solids 1 materials being suitable for a magnetic connection are arranged, so e. g. onto the spherical surface 2 s spherical zone 21 is placed, which may be slided or turned on the spherical surface 2; in or on the spherical zone 21 there are one or more magnets or elements being suitable for a magnetic connection arranged.
The solids 1 are of the shape of a halved slice of orange, this form is obtained in such a manner that the sphere consisting of the solids 1 is partly intersected by a plane passing through its centre, partly the sphere is intersected by planes lying perpendicularly to the first plane of intersection, while said planes are enclosing an angle of /n with one another ( see Fig. 16).
In order to be able to perform accurate adjustment, after having been turned-off, the solids 1, i. e. the group 7 of the solids are to be arrested in their position.
According to a preferred embodiment arrestment is to be performed, so, that on the inner surfaces of the solids 1 being mutually in contact an arresting boss 23 is arranged, which can be pushed in direction of the inside of the solids 1 against the force of a spring 22, while on the side feeing the boss 23 a notch 24 is formed. Preferably the boss 23 has the shape of a sphere (Fig. 15).
In case, if the large cube 4 to be seen in Fig, 1 on each single surface of the solid 1 having been fixed onto the spherical surface 2 and sliding on the other solids, at least one boss 23 is placed, it seems to be sufficient to form only notches 24 on the contacting surfaces of the remaining solids 1, then the arrested rotation can be ensured in any rotated position. In a similar manner, the arrestment of any other shaped solids becomes possible.
It goes without saying that the shape of the playsurfaces 6 may differ from the faces of the large cube 4 serving here as an example, so e. g. the playsurfaces 6 may be formed with optional plain or spherical surfaces; when the logical toy according to the invention is realized in form of a sphere, it may have one single playsurface 6, this may happen, in particular, by reshaping the large cube 4 according to Fig. 3 into a sphere, however, an appearance of the toy in form of a prism, tetrahedron, etc. is also possible.
