A LOGICAL TOY HAVING MOVABLE UNITS AS COMPARED TO EACH OTHER AND TO THE CORE

Abstract: A logical toy having movable units relative to each other and the core which in certain positions form a regular geometric body, preferably a body enclosed by body plates, similar to each other. The essence of the logical toy is that the body plates forming the body are triangle which are parts of certain moving units and the momentary moving unit together with a group of the body plates forms a pyramid. According to another embodiment of the invention the body plates are pentagons and the momentary moving unit formed with the otherbody plates is a truncated pyramid. According to still another embodiment of the invention the body plates are spherical surfaces or other curved surfaces and have on the surface of the geometric body spherical pentagons or other pentagons of curved surface, which are determined by the contours of the rotation planes of the moving units.

Description: A Logical Toy Having Movable Units as Compared to Each Other and to the Gore. TB0KK.ICAL glΞ D The field of the invention coneerne such a logical toy which has got mobile units. They can be dis¬ placed as compared to each other and to the core. The proposed logical toy can be applied according to the different rules which can be created by the players, too. The logical toy can also be applied to competitions, group or team games. But first of all it serves the purpose of individual amusement. B 7 means of the invented logical toy depth perception, knowledge of solid geometry and the logical way of thinking can be developed to a great extent. BACiCGBOUNI) ABT Some logical toys, similar to the invented logical toy but of another construction have already been known. The best known logical toy can be learnt from the patent specification Ηo . 173062 MU PS. The logical toy described in the mentioned patent specification consists of a cuboid. Its plates are formed by small cubes. The movable unit, consisting of small cubes can be turned as compared to a core. The movable unit consists of small cubes which form a plate of the big cube and other components, belong¬ ing to this movable unit. Generally that building style is practically applied where each plane con¬ sists of nine small cubes. The small cubes are the body elements of the geometric body regarded as the logical toy. According to their position and role three types of body elements i.e. small cubes can be distinguished. There are corner elements, central unit elements and insert ones being joined to the corner elements. The corner elements can never take the place of insert ones that is also true inversely. The central unit elements are such cubes - small cubes - which are set to the middle of the geometric body's - big cube - plates and they cannot be displaced as compared to the core. On applying the briefly described logical toy the players have usually got to arrange the body elements, placed at random, considering the coloured surfaces of the small cubes - as body elements - so that each plate of the geometric body consist of elements of the same colour.. Briefly, each plate of the big cube must consist of small cubes' plates of the same colour. The described logical toy has got a considerable disadvantage, amely that the logical toy's/ eometric body's/elements' movement is restricted in different ways. Accordingly, the logical toy, apart from some games, cannot provide any other game possibilities. Therefore the mentioned logical toy soon becomes boring or even dull. Some other logical toys, derivable from or similar to the above mentioned are also known, which consist of mobile body elements as compared to each other, or movable units, constructed of them. The statement made in relation to the subject of the patent specification fi . 173062 i-iTJ PS hol s true of them, as well, to some extent. _0 PI DISCLOSURE OF IUVENTIO-K The aim of the invented logical aim is to allow follow-ing various game rules at different difficulty levels and offer more combination possibilities in comparison to the existing lo gical toys. It is the construction of* the invented lo gical toy which allows to achieve the objectives. Its geometric body - in case if the surface or sur- face parts are asymmetric, - as to the frame of the toy - if it encloses triangular , five-angled or curved surfaces (favourably spherical surfaces) , accordingly, each of its movable units is a pyramid , a truncated pyramid , a sphere slice or a unit near the deformed spherical surface that can be partly covered with a spherical surface . Accordingly, the invented lo gical toy can have three variations. The symmetric geometric bodies differ from each other in the shape of the enveloping plates. Each of the body plates can be modified by colo uring or apply-ing a cover that changes the surface' s original plane or shape . These are generally called plate modifiers. By the help of the plate modifiers the logical toy' s geometric body can be enlarged or reduced in size as compared to the original plane of the body plate. A way of modifying the invented lo gical toy is to apply multi-colour surfaces to its body plates. The invented lo gical toy can become more complicated if certain marks are applied to the body plates. They can be numbers, figures, different protruding or sunk configurations. Such a configuration can be applied to the body plates e.g. that can be well understood by blind people as well, for they are holes forming braille. Each movable unit of the-.invented logical toy con- sists of body elements, different building units or perhaps a rotation axis belonging to them. The invent¬ ed logical toy also has three types of body elements. Among them the central unit elements is the motion central part of the movable unit. Its motion is highly restricted. The other two body elements are the edge element and plate element. In general it is only the central unit elements that must be connected with the core, whereas the other body elements - i.e. edge elements and plate elements - are fixed by the prevailing adjacent elements by means of their curved sur aces allowing different relative motions. The system of the body elements belong.ing to the movable units can be considered as the shell of the logical toy's geometric body, because the coherent set of shells form its surface layer. The core inside the geometric body can be accomplished as a solid unit so that only the adjusting gaps, necessary to the dis¬ placement be between the core and body elements constituting the shell. The core can also be made in a way that the geometric body of the logical toy form a hollow body. As regards manufacturing, both the body elements and the core can consist of some parts. Prom the above mentioned it emerges that the central unit element of each movable unit of the logical toy's geometric body must be connected to the core in such a way that the necessary removal - generally turning - be provided. Por the sake of this it is the rotation axis that connects the central unit element to the core. The geometric median of each rotation axis, as a building unit, must coincide with a body axis of the geometric body. In most cases it is satisfactory if simple screws, e. g. wood-screws are applied as rotation axes. Por the sake of providing a flexible turning it seems expedient to supply the screv/s as rotation axes, with spring support. Por the sake of widening the combination possibilities offered by the invented logical toy, and providing more game variations certain central unit elements are supplied with clamping organs. They can be pins 7/hose medians do not coincide with that of the rotation axis and the body axis of the geometric body. The clamping organ can be such a pin which is tightly adjusted to the core, whereas its adjustment to the central unit element allows motion. The clamp¬ ing organ's threaded part can be attached to the threaded hollow of the core and its smooth surface is connected with the central unit element, allowing motion. The essence of one of the invented logical toy's version is that its body plates are triangles that can be attached to some movable units .in succession, and each momentary moving unit forms a pyramid together with a group a group of the body plates. This version of the invented logical toy is practicaUl an icosahedron. The essence of another version of the invented logical toy is that its body plates are pentagons and each of its momentary moving units form such a truncated pyramid who se cover is one of the five- angled body plates. The geometric body of such a logical toy is essentially a pentagonal dodecahedron. The essence of the third version of the invented logical toy is that its body plates are spherical or curved, and it has got spherical pentagons or other curved surface pentagons formed by the object lines of the moving units' rotation planes. A avourable building style of any of the invented logical toy' s versions can be achieved by apply.ing modifiers to some body plates. The modifiers are configurations extending towards the inside of the geometric body or outwards as compared to the plane or i againary plane of the body plates. They are ■ separate bodies attached to , adj usted to or fixed on the body plates or indicating their deformation. The accomplished geometric body of the invented logical toy' s shell belonging to the surface or the visible surface itself consist of three types of body elements, i. e . central unit elements, edge elements and plate elements. One of the expedient building styles of the invent- .ed logical toy' s body plates is supplied with one colour or has got another mark. In case of another building style each body plate has got multi-coloured surfaces or different marks. In case of a building style of the invented logical toy at least one central unit element is attached to the core with a rotation axis. Expediently, the rotation axis is a spring supported screw. A clamping organ, connecting each central unit element to the core is applied to the toy. It can be either a pin or a threaded pin. The motion of the central unit element can. be f vourably promoted if the surfaces of the central unit element and the core, opposite . to each other have got guide grooves or rib guides of annular type.

BEST MODE OP CARRYING OUT THE -H TlOfi The building style of the invented logical toy is an icosahedron shown in Pigure 1. Accordingly, the ^0 logical toy' s body has got 20 triangular plates, 30 edges and 12 peaks. Each body plate (L) of the geo¬ metric body is coloured. In this case the letters a, b , c , d, e stand for different colours. In case of the sketched geometric body each peak, marked with 1 letters A, B, G, D, E - etc . - unites the peaks of 5 triangular body plates (L) . The sides of the body plates (L) opposite the body peaks level with each other . Let ' s examine e . g. peak A and the body plates (L) belonging to it. 5 triangular body plates 0 (L) meeting in peak A constitute a five-angled pyramid. The reference plane of this pyramid is en¬ closed by the sides of the triangles opposite peak A. One of the body axes of the icosahedron is the per¬ pendicular dropped to the reference plane of the 5 pyramid from peak A. If a coaxial rotation axis is provided with the body axis, the body plates (L) meeting in peak A - together with other elements - can constitute a movable unit (M) . Likewise , provid¬ ing a necessary structural division, the five-angled 0 pyramidal parts, enclo sed with peaks B, G, etc . can also constitute a movable unit (M) . By means of a construction to be described later, it can be pro¬ vided that each body plate (L) of the logical toy's geometric body being an icosahedron, be connected to three movable units ( ) .in succession. Under these conditions each body plate (L) can be removed any¬ where along the surface of the icosahedron, so theoretically can be connected with every other body plate (L). As to the building style shown in Pigure 1., the icosahedron, being the logical toy's geometric body is shown in a position where each body plate (L) meeting in peak A is of different colour. One of the games which can be played with the logical toy is that the body plates (L) of the icosahedron must be arranged so that the triangles, belonging to each peak be of different colours. Por the sake of the defined objective the momentary movable units (M) must be turned. Essentially, another logical toy, providing more game possibilities but of the same construction as the geometric body shown in Pigure 1. can be accomplished ±f colouring shown in Pigure 2. is applied. In this case each body plate (L) is of three colours. The surface parts of different colours are partly enclosed with the contour lines, or more properly with the.ir sections of a body plate (L). A position where each peak is determined by surface parts of the same colour only, can always be provided. As to the position shown in Pigure 2., peak A. is constituted with surface parts of colour d only, peak B is constituted with surface parts of colour f only, etc. Six colours, marked with letters a-f have been applied to this building style. The logical toy to which the above colouring is applied can provide more game possibilities and combination versions than the one shown in Pigure 1. and is more clear-cut. Theoretically, its construction can be the same as that of the ver¬ sion shown in Pigure 1. The body plates of the logical toy's icosahedron can be coloured in a way that each body plate (L)'s * surface parts of different colours be partly en- closed with certain sections of the bisectors of the icosahedron's triangled body plates. This building style has not been shown in Pigures. The structure of the geometric body, being coloured in the way mentioned above, can be the same or similar to that of the versions shown in Pigures 1. and 2. The inside of the icosahedron, regarded as the invented logical toy's geometric body is shown in Pigure 3» and 4. providing a detailed survey of its construction and operation. Certain building units - e.g. rotating axes, applied springs, clamp¬ ing organs - have been omitted, so the other elements can be well seen. The core is not shown in ny of the Pigures, either. Pigure ^ 3» shov/s the connection between the centra unit elements (T,), edge-elements (T ) and plate elements (T . The axes X of the geometric body coincide with the mediane of the central unit elements (T,,). Certain sections of the central unit elements (T,,) cannot be directly seen on the surface of the icosahedron because their peaks are broken by planes 2. In case if the spring is not sunk, the head of the screw, considered as the rotation a.xis, is attached to the central unit element (T^), on plane 2. The Pigure shows the hollows O:*PI (8) into which the mentioned screw heads are placed. Evidently, the structure part above plane 2, being the pin head (3) cannot take a place larger than the one, removed by a section along plane 2 from the central unit element (T,,), otherwise the plate elements (T- couldn't move. Each movable unit (M) can be turn¬ ed round a rotation surface (S). The core (1) of the geometric body of an icosahedron type can be a dodecahedron. But the core (1) can be of different type, too, e.g. spherical. The complexity of parts shown in Pigure 3- is called the shell of this building style of the invented geometric toy. The building units, not shown in this Pigure also belong to it. Pigures 5 and 6 show the structural connection between the core (1) and the central unit element (T.-) of a building style of the invented logical toy. It is clearly seen in Pigure 6. that the geometric ' median of a central unit element (T,) coincides with one of the body axes X of the core (1). There is a centre hollow both in the central unit element (T,,) and the core (1) that coincides with the body axis (X). This hollow (8) has got a shoulder in the central unit element (T, j ) and the screw (7)j supported by it is prestressed by the head of the screw (6). The screw (6) is regarded as the rotation axis of the central unit element T ^ ,) shown in the Pigure. In case of this building style it is a wood screw (6) whose threaded part is placed in the core (1). A section of the screw (6) placed in the central unit element (T ^ , is adjust¬ ed to the hollow (8) so that the central unit element (T^ can be easily turned as compared to the screw (6). -fUR The building style shown in Pigures 5 end 6, has got a clamping pin. (4). It can be seen that the medium of the pin (4) deviates from that of the screw (6) and the body axis (X), as well. As to this case, the pin (4) is tightly adjusted to the hollow of the core (1) and it is loosely ad¬ justed to the hollow of the central unit element. The hollow (8) is sealed up by a plu (5) and the head (3) of the pin (4) is supported by it. In case if there is a pin (4) in the toy, as it is shown in Pigures and 6 the central unit element (T,,), supplied with it cannot be turned as compar¬ ed to the core (1). The plate elements (T » if necessary, must be supplied with breaks so that the pin (4) be placed or removed. The central unit element ( ^ can be turned as compared to the core (1) if a guidance is provided to make the central turning possible. The guiding grooves (9) and rib guides (10), attached to them serve for this purpose. Both the guiding grooves (9) and rib guides (10) are annular. Pigures 7 and 8 show the building style of the central unit elements (T,,) and the core (1) having no clamp.ing organs. In this case the core (1) is provided with different studs. Pigure 7 shows only a part of a stud. The Pigures mentioned above show a central unit element (T^ of this buildin style which is similar to a truncated pyramid.The screw (6) is in the hollow (8) with a shoulder. Its head, on condition if it is screwed in, pre- stresses the spring (7). The guide groove (9) and the rib guide (10) adjusted to it can be well seen. As they are annular can provide guidance of the central unit element (T,,) in the course of turning. Pigures 9-12 show a building style of the edge element (T p ). The edge (11) of the edge element (T p ) is outwards and its different surfaces provide relative displacements as compared to the adjacent plate elements (To) and the guidance of the momentary adjacent elements in the course of displacement. The surfaces of the edge elements (T ) In case of a building style, as well as their angles can be drawn or computed. Pigures 13-15 show a building style of the plate element (To). Each surface part of the plate element (To) and the angles belonging to them can be drawn or computed. The body elements (T), i.e. the central unit element (T ^ .), edge elements (To) and plate elements (To) are not connected with the core (1) except for the central unit elements (T,»). The edge elements (T p ) and plate elements (To) shown in Pigures 3 and 4 are assured aga^Lnst dropping out by the momentary adjacent building units, on the other hand their dis¬ placement as compared to each other, is provided by the attached surfaces, too. Pigure 16 shows a plate modifier (12). The triangle whose vertices are marked with letters A, B, C, can be adjusted to a body plate (L) of the icosahedron and it is fixed. A pyramid extrudes from the plane enclosed with the peaks A, B, C. It has got 13 peaks. The pyramid edges (14) belong to the 13 peaks. In case if a plate modifier (12) is applied, the edges (14) meeting in one peak of the icosahedron, and and accordingly the peaks (13) belonging to them, level with each other. The application of the plate modifiers (12) - the one mentioned above and some other types - can contribute to widening the combinations, besides, it can facilitate the handl¬ ing of the logical toy, too. In case if a movable unit ( ) of the icosahedron is turned - if a plate modifier (12) is applied - the fingers can be firmly supported and a bigger moment is provided for turn- ~- B- whereas the same force is exerted. Up to this point such a version of the invented logical toy has been described where the geometric body of the toy was an icosahedron. The body elements, constituting the icosahedron - and in case of necessit certain building units, too, - can be altered so that the body is still an icosahedron but the components can be changed in another way, as well, and a new geometric body can be created. The alterations can be reduction, extention and other deformations. Pigure 17 shows a version of the invented logical toy, whose geometric body is a pentagon dodecahedron. Accordingly, the body plates (L) are regular pentagons. There are 12 of them. Besides, there are 20 peaks, 30 edges and 12 axes. Essentially, each movable unit (M) of the geometric body is a truncated pyramid with a five-angled reference plane. The cover of this trun¬ cated pyramid is a pentagon. It can be derived from the icosahedron shown in Pigures 1 and 2. That pyramid has been a movable unit (M) of the icosahedron. Its poll- ing plane is parallel with the reference plane of the pyramid. The central part of each body plate (L) of the dodecahedron is a regular pentagon which seems to be the cover of the central unit element (T,,). The central unit element (T^) of this building style is O not hidden as that of the formerly described icosahedron. Pigure 17 shows a geometric body whose reference plane of each movable unit ( ) has got the bottom peaks of the formerly described truncated pyramid on it. In this Pigure the reference planes of each movable ' unit (M) and the rotation planes are de¬ termined by peaks 21, 22, 23 - 24 and 25. The movable unit (M) of the building style shown in the Pigure has got a cover which is a plane with peaks 31, 32,. 33, 3 - and 35 on it. In case of this building style on each body plate (L) there are 5 rhombuses ( ) » 5 triangles (16) and in the middle there is a pentagon which is the cover of the central unit element T> j at the same time. There are al¬ together 132 plane figures on the surface of the whole geometric body. By the help of colouring these plane figures, different rule pollibilities can be provided. As to the building style shown in Pigure 17 every plane figure of each body plate (L) is supposed to be of the same colour. Accordingly, each plane figure of the body plate (L) parallel with the plane of the drawing is of colour _§. Pigures 18 and 19 show sections or views after re- moving certain parts, allowing to have a look at the dodecahedron's inside. Por the sake of having a better view, the core is not shown in Pigures 18 and 19. Three versions of the body elements (T) can be also recognised in these Pigures, too, i.e. central unit elements (T, j ), edge elements (T p ) and plate elements . In accordance with the altered form of the logical toy's geometric body, the body elements (T) are to be altered to some extent, too. The modifie body elements (T), considering the altered geometric relationships, can be determined. Pigure 18 shows that the medians of the dodeca¬ hedron's rotation axes coincide with the body axes X of the geometric body. In this case the screws can also be regarded as rotation axes taking place in the hollows (8) of the central unit elements (T^). In case of this building style it is also sufficient if only the central unit elements (T^) are connected with the core, whereas all the other body elements are supported with the momentary ad¬ jacent body elements. The displacement and turning, as compared to each other are provided by the sur¬ faces of the adjacent body elements attached to each other. The game can become more complicated if certain movable units (M) are fixed, i.e. certain central unit elements (T^) are cupplied with clamp¬ ing organs. In case 1£ the geometric body of the logical toy is a pentagon dodecahedron, the aim of the game is to rearrange the geometric body, made up of differently arranged surface parts of different colours by turn¬ ing the movable units (M) so that in the end each body plate (L) must consist of surface parts of the same colour. By means of applying different colours, or plate modifiers or configurations, some more variations can be provided without essentially chang¬ ing the construction of the invented toy or its geometric body. Pigure 20 shows a version of the invented logical toy whose geometric body is a sphere. On its surface the object lines of each movable unit ( )'s rotation plane can be well recognised. These object lines are circles (18). The circular (18) planes and the spherical shells belonging to them make up the envelope surface of each movable unit (M). Similarly to the formerly described two variations of the logical toy, this version has got 12 body axes (X). They coincide with the medians of the movable units' ( ) rotation axes that belong to them. This version has got 12 pentagons (17) on its surface, which are spherical. As to the function of the pentagons (17) and the bodies, belonging to them which extend towards the inside of the geometric body, they correspond with the central unit elements (T,,) formed by the truncated pyramids with the five-angled refer¬ ence plances of the dodecahedron. The pentagons (17) are the external enveloping plates of the central unit elements (T^). The rotation planes of each mova- ble unit (M) and the circles (18) serving as the lines of intersections of the geometric body's sur¬ face determine different configurations. There can be such forms (19)} spherical triangles. One of them is determined by points 26, 27 and 28, and connect- ing arcs. Beside the above mentioned figures (19) such figures (20) can also be recognized. One of them is determined by points 26, 27 » 29 and 30 and connect¬ ing arcs. Por providing easier turning of the movable units (LI) it is advantageous if inside a version there are holes or protuberances. Pigure 20 shows a building style where each figure (19) i supplied with a hole. One of them is shown as a figure determ-in- ed by lines 36, 37 and 38. In the latter case body elements, building units and other accessories, making up a movable unit can be also determined and made. The version of this build¬ ing style can also have rotation axes as those versions whose geometric body is an icosahedron or a pentagon dodecahedron. ' B y The building style shown in Pigure 20 can be made less or more complicated in the following way: by applying different colours to the figures 19 and/or 20 on the geometric body' s surface and to the pentagons (17) » as well as different con¬ figurations and plate modifiers. The described versions of this building style indicate that the invented logical toy can pro¬ vide a large number of d.ifferent, more or less complicated games and there is no need for more technological efforts to be made than those having already been applied to the existing logical toys.
