Description

Die Erfindung betrifft ein Gestaltungsspielzeug mit der Grundform einer geraden Stange, welches aus aneinandergereihten, miteinander verbundenen Bausteinen zusammengesetzt ist, von denen jeder mit seinen beiden Stirnseiten zwei im gleichen oder entgegengesetzt gleichen Winkel zur Stangenlängsachse geneigt verlaufende Verbindungsflächen bildet und von denen die jeweils aneinandergrenzenden Bausteine mit ihren einander benachbarten, deckungsgleich ausgebildeten Verbindungsflächen aneinanderliegend um eine durch deren geometrischen Mittelpunkte verlaufende Verbindungsachse gegeneinander verdrehbarfedernd aneinander gehalten sind.The invention relates to a design toy with the basic shape of a straight rod, which is composed of lined up, interconnected building blocks, each of which forms with its two end faces two connecting surfaces inclined at the same or opposite angle to the longitudinal axis of the rod and of which the adjacent building blocks with their mutually congruent, congruently formed connecting surfaces are held against one another in a mutually rotatable manner about a connecting axis running through their geometric center points.

Es ist ein Gestaltungsspielzeug bekannt (US-A-3773329), welches aus aneinandergereihten quaderförmigen Bausteinen besteht, bei denen die Seitenkanten doppelt so lang sind wie die Kantenlänge ihrer Stirnflächen und die paarweise aneinandergrenzend um jeweils einen senkrecht zu ihren Verbindungsflächen, mit denen die jeweils aneinandergrenzenden Bausteine aneinanderliegen, verlaufenden Verbindungszapfen gegeneinander verdrehbar sind. Einer der Bausteine liegt mit seiner Stirnfläche an der einen Hälfte einer der Seitenflächen eines ihm benachbarten Bausteins an, wobei der Verbindungszapfen dieser beiden Bausteine durch den geometrischen Mittelpunkt der Stirnfläche des einen Bausteins und durch den Mittelpunkt der Hälfte der Seitenfläche des anderen Bausteines verläuft, die somit in allen Drehstellungen über die Stirnfläche des benachbarten Bausteins seitlich hinausragt. Alle anderen jeweils aneinandergrenzenden Bausteine hingegen liegen mit einer ihrer Seitenflächen aneinander, wobei ihr jeweiliger Verbindungszapfen gegenüber dem geometrischen Mittelpunkt der aneinanderliegenden Seitenflächen versetzt in Höhe eines Viertels der Länge der beiden Flächen angeordnet ist, so dass diese in der einen Drehstellung der jeweils benachbarten Bausteine deckungsgleich aufeinanderliegen und in allen anderen Drehstellungen übereinander vorstehen. Die Bausteine sind derart aneinandergereiht, dass sie durch ihr gegenseitiges Verdrehen in die Form eines länglichen quaderförmigen Körpers gebracht werden können. Da hierbei wenigstens einer der Bausteine an einem der anderen Bausteine derart vorbeigedreht werden muss, dass er mit dessen einen Seitenfläche kollidiert, ist wenigstens einer der Verbindungszapfen, jedoch nicht jeder, in Längsrichtung federnd abgestützt, so dass die über diesen Verbindungszapfen benachbarten Bausteine um ein begrenztes Mass federnd voneinander abgehoben werden können. Hierzu ist in dem einen Baustein ein Hohlraum ausgebildet, in dessen einen Begrenzungswand, an welcher der andere Baustein anliegt, eine Bohrung ausgebildet ist, durch welche der an beiden Enden einen Kopf aufweisende zylindrische Zapfen gesteckt ist. Zwischen dem einen in dem Hohlraum liegenden Kopf des Zapfens und der die Bohrung aufweisenden Begrenzungswand des Hohlraums ist eine Druckfeder eingespannt und mit dem anderen Kopf ist der Zapfen in dem anderen Baustein verankert. Wenn die Bausteine entsprechend gross bemessen und aus bezogenem Schaumstoff oder Polstermaterial hergestellt werden, soll nach dem bekannten Vorschlag anstelle eines Gestaltungsspielzeuges ein in seiner Form verwandelbares Sitzmöbelstück entstehen.A design toy is known (US-A-3773329), which consists of lined up cuboid blocks, in which the side edges are twice as long as the edge length of their end faces and the pairs adjoining one another perpendicular to their connecting surfaces, with which the adjoining ones Modules lie next to each other, extending connecting pins can be rotated against each other. One of the building blocks rests with its end face on one half of one of the side faces of a building block adjacent to it, the connecting pin of these two building blocks running through the geometric center of the end face of one building block and through the center of half of the side face of the other building block, which thus protrudes laterally in all rotational positions beyond the end face of the neighboring building block. On the other hand, all of the other adjoining building blocks lie against one another with one of their side surfaces, their respective connecting pins being offset from the geometric center of the adjoining side surfaces by a quarter of the length of the two surfaces, so that they lie congruently in one rotation position of the adjacent building blocks and protrude one above the other in all other rotational positions. The building blocks are lined up in such a way that they can be brought into the shape of an elongated cuboid body by their mutual twisting. Since at least one of the building blocks has to be rotated past one of the other building blocks in such a way that it collides with its one side surface, at least one of the connecting pins, but not all, is resiliently supported in the longitudinal direction, so that the building blocks adjacent to these connecting pins are limited Mass can be lifted apart from each other. For this purpose, a cavity is formed in one component, in whose one boundary wall, on which the other component bears, a bore is formed, through which the cylindrical pin having a head at both ends is inserted. A compression spring is clamped between the head of the peg lying in the cavity and the boundary wall of the cavity having the bore, and the peg is anchored in the other module with the other head. If the building blocks are sized appropriately and are made of covered foam or upholstery material, the known proposal is to create a piece of seating furniture that can be transformed in place of a design toy.

Ein anderes als gerade Stange ausgebildetes Gestaltungsspielzeug (DE-U-70095541) besteht aus aneinandergesetzten Würfeln, die jeweils diagonal halbiert sind und mittels einer Gummischnur, die in der Längsrichtung der als gerades viereckiges Prisma ausgebildeten Stange verläuft, verdrehbar aneinander gehalten sind. Jeder der aus den Würfelhälften gebildeten Bausteine weist daher zwei Verbindungsflächen auf, mit denen er an dem jeweils benachbarten Baustein anliegt, und ist seinerseits als gerades Prisma ausgebildet, dessen Grundfläche und Deckfläche ein gleichschenkliges rechtwinkliges Dreieck bildet. Jeweils von der einen der gleichen Schenkelseiten der gleichschenkligen Grundfläche und Deckfläche ist die eine, quadratisch ausgebildete Verbindungsfläche des Bausteins begrenzt, dessen andere Verbindungsfläche zwischen den als Hypotenuse der Grundfläche und Deckfläche von deren gleichen Schenkelseiten verschieden ausgebildeten Dreiecksseiten verläuft und daher als von einem Quadrat verschiedenes Rechteck ausgebildet ist. Während somit die eine Verbindungsfläche jedes Bausteins als regelmässiges Vieleck, nämlich als Quadrat, ausgebildet ist und senkrecht zu der Stangenlängsachse verläuft, ist die andere Verbindungsfläche als unregelmässiges Vieleck ausgebildet und verläuft zur Stangenlängsachse geneigt. Für die mit den quadratischen Verbindungsflächen aneinanderliegenden benachbarten Bausteine gibt es daher entsprechend der Anzahl der Ecken des Quadrats vier Relativdrehstellungen, in denen die Verbindungsflächen deckungsgleich aufeinanderliegen. Durch das Verdrehen der über diese Verbindungsflächen benachbarten Bausteine ändert sich jedoch ohne gleichzeitige Verdrehung anderer, über rechteckige Verbindungsflächen benachbarter Bausteine die Form des Gestaltungsspielzeuges nicht, weil die quadratischen Verbindungsflächen senkrecht zur Stangenlängsrichtung verlaufen. Für die rechteckigen Verbindungsflächen aneinandergrenzender Bausteine hingegen gibt es zwei um 180° gegeneinander versetzte Relativstellungen, in denen diese Verbindungsflächen deckungsgleich aufeinanderliegen, und da diese zur Stangenlängsrichtung um 45° geneigt verlaufen, ändert sich die Form des Gestaltungsspielzeuges durch das Verdrehen der über die rechteckigen Verbindungsflächen benachbarten Bausteine um 180° zu einem Winkelstück. Mit diesem Gestaltungsspielzeug können daher je nach den Relativstellungen, in denen die Bausteine mit ihren Verbindungsflächen deckungsgleich aufeinanderliegen, ebene oder räumliche Figuren erhalten werden, bei denen jedoch nur rechtwinklige Abwinklungen möglich sind und die über die rechteckigen Verbindungsflächen benachbarten Bausteine gemeinsam stets einen Würfel bilden.Another design toy designed as a straight rod (DE-U-70095541) consists of cubes placed one on top of the other, each of which is diagonally halved and rotatably held together by means of a rubber cord that runs in the longitudinal direction of the rod, which is designed as a straight, square prism. Each of the building blocks formed from the cube halves therefore has two connecting surfaces with which it abuts the adjacent building block and is in turn designed as a straight prism, the base and top surface of which form an isosceles right-angled triangle. One of the same leg sides of the isosceles base and top surface delimits one square connection surface of the module, the other connection surface of which runs between the triangular sides of the base and cover surface, which are differently designed as hypotenuses of the base side and cover surface, and therefore as a rectangle different from a square is trained. Thus, while the one connecting surface of each module is designed as a regular polygon, namely as a square, and runs perpendicular to the longitudinal axis of the rod, the other connecting surface is designed as an irregular polygon and is inclined to the longitudinal axis of the rod. For the adjacent building blocks with the square connecting surfaces, there are therefore four relative rotational positions corresponding to the number of corners of the square, in which the connecting surfaces lie congruently on one another. By rotating the building blocks adjacent to these connecting surfaces, however, the shape of the design toy does not change without simultaneously rotating other building blocks neighboring by rectangular connecting surfaces, because the square connecting surfaces run perpendicular to the longitudinal direction of the rod. For the rectangular connecting surfaces of adjacent building blocks, on the other hand, there are two relative positions offset by 180 °, in which these connecting surfaces are congruent with each other, and since they are inclined at 45 ° to the longitudinal direction of the bar, the shape of the design toy changes due to the twisting of the neighboring ones via the rectangular connecting surfaces Blocks at 180 ° to an elbow. With this design Depending on the relative positions in which the building blocks are congruent with one another, toys can therefore be obtained as flat or spatial figures, but only rectangular angles are possible and the building blocks adjacent to one another via the rectangular connecting surfaces always form a cube.

Bei einem anderen bekannten Gestaltungsspielzeug (US-A-3597872) mit den eingangs erwähnten Merkmalen hingegen sind beide Verbindungsflächen jedes Bausteins zur Stangenlängsachse geneigt und verlaufen im Winkel zueinander, so dass durch das gegenseitige Verdrehen einander benachbarter Bausteine in solche möglichen Stellungen, in denen ihre gemeinsamen Verbindungsflächen deckungsgleich aufeinanderliegen, das stangenförmige Gestaltungsspielzeug sich um andere Winkel als 90° abwinkeln lässt und dabei sich auch die Gesamtform der aneinandergrenzenden Bausteine ändert. In der bevorzugten Ausführungsform des bekannten Gestaltungsspielzeuges haben dessen Bausteine eine zylindrische Oberfläche und, mit Ausnahme der beiden Endbausteine, einen als gleichschenkliges Trapez ausgebildeten Längsschnitt, so dass ihre Verbindungsflächen Ellipsen sind und daher zwei Relativstellungen möglich sind, in denen benachbarte Bausteine mit ihren Verbindungsflächen deckungsgleich aufeinanderliegen. In der Grundstellung der Bausteine hat das bekannte Gestaltungsspielzeug die Form einer geraden Stange, aus welcher sich durch die Verdrehung einander benachbarter Bausteine um 180° nur ebene Formänderungen, wie geometrische Figuren, einfache Buchstaben und Zahlen und dergleichen, bilden lassen. In anderer Ausgestaltung können die Bausteine anstelle der Zylinderform auch eine andere Form haben, wie z.B. als Stern oder als Kugelteil ausgebildet sein. Wenn aber die Bausteine als aneinandergereihte Kugelteile ausgebildet sind, die jeweils zwei im Winkel zueinander verlaufende ebene Verbindungsflächen aufweisen, mit denen einander benachbarte Bausteine deckungsgleich aufeinanderliegen, lässt sich das Gestaltungsspielzeug durch das Verdrehen der Bausteine nicht in die Form einer geraden Stange bringen.In another known design toy (US-A-3597872) with the features mentioned above, however, both connecting surfaces of each block are inclined to the longitudinal axis of the rod and run at an angle to one another, so that by mutually rotating adjacent blocks in such possible positions in which their common The connecting surfaces are congruent with one another, the rod-shaped design toy can be angled at angles other than 90 ° and the overall shape of the adjoining building blocks also changes. In the preferred embodiment of the known design toy, its building blocks have a cylindrical surface and, with the exception of the two end building blocks, a longitudinal section formed as an isosceles trapezoid, so that their connecting surfaces are ellipses and therefore two relative positions are possible in which neighboring building blocks are congruent with one another with their connecting surfaces . In the basic position of the building blocks, the well-known design toy has the shape of a straight rod, from which, by rotating adjacent building blocks by 180 °, only flat shape changes, such as geometric figures, simple letters and numbers and the like, can be formed. In another embodiment, the blocks can also have a different shape instead of the cylindrical shape, such as be designed as a star or as a spherical part. However, if the building blocks are formed as a series of spherical parts, each with two planar connecting surfaces running at an angle to one another, with which neighboring building blocks are congruent, the design toy cannot be brought into the shape of a straight rod by twisting the building blocks.

Ferner weist auch dieses Gestaltungsspielzeug als Verbindungsachse der Bausteine eine gespannte, von dem einen Endbaustein zu dem anderen hin durchgehende Gummischnur auf, die wegen der Neigung der Verbindungsflächen der Bausteine zur Stangenlängsrichtung nicht senkrecht zu den jeweiligen Verbindungsflächen verläuft und während und nach dem Verdrehen der Bausteine in Höhe der jeweils aufeinanderliegenden Verbindungsflächen geknickt wird. Dadurch verläuft auch die resultierende, durch die gespannte Gummischnur erzeugte Federkraft nicht senkrecht zu den Verbindungsflächen und ausserdem wird die Gummischnur beim Spielen mit dem bekannten Spielzeug durch jedes Verdrehen einander benachbarter Bausteine an deren gemeinsamen Verbindungsflächen hin- und hergeknickt, so dass an den Knickstellen die Gefahr einer Überdehnung und des Abscherens an den Lochkanten der die Bausteine durchlaufenden, die Gummischnur aufnehmenden Bohrungen besteht. Dadurch sind die Strapazierfähigkeit und die Lebensdauer des Spielzeugs beeinträchtigt. Da ausserdem die Bausteine für ihr gegenseitiges Verdrehen zumeist etwas auseinandergezogen werden, ist diese Gefahr der Überdehnung der Gummischnur an ihren Knickstellen umso grösser, je stärker sie für ein Spielzeug gespannt ist, das in jeder Gestalt nur aufgrund der zwischen ihren Bausteinen wirkenden Reibungskräfte selbsttragend formbeständig sein soll. Durch die Erfindung wird die Aufgabe gelöst, ein stangenförmiges Gestaltungsspielzeug mit den eingangs erwähnten Merkmalen derart auszugestalten, dass beim Verdrehen der Bausteine zur Ausbildung vielfach unterschiedlicher ebener und räumlicher Figuren, in denen ihre Verbindungsflächen deckungsgleich aufeinanderliegen, eine Überlastung der Verbindungsachse vermieden ist.Furthermore, this design toy also has a tensioned rubber cord as a connecting axis of the building blocks, which runs from one end building block to the other, which because of the inclination of the connecting surfaces of the building blocks to the longitudinal direction of the bars does not run perpendicular to the respective connecting surfaces and during and after the twisting of the building blocks in Height of the connecting surfaces lying on top of each other is kinked. As a result, the resulting spring force generated by the tensioned rubber cord does not run perpendicular to the connecting surfaces and, moreover, when playing with the known toy, the rubber cord is bent back and forth by twisting adjacent building blocks at their common connecting surfaces, so that the danger at the kink points overstretching and shearing off at the perforated edges of the holes passing through the building blocks and receiving the rubber cord. This affects the durability and lifespan of the toy. In addition, since the building blocks for their mutual twisting are usually pulled apart somewhat, the risk of the rubber cord being overstretched at its kink points is greater, the more it is stretched for a toy that in any shape is only self-supporting due to the frictional forces acting between its building blocks should. The invention achieves the object of designing a rod-shaped design toy with the features mentioned at the outset in such a way that when the building blocks are rotated to form many different planar and spatial figures in which their connecting surfaces are congruent with one another, the connecting axis is not overloaded.

Dies wird gemäss der Erfindung dadurch erreicht, dass die Verbindungsachse aus Achsteilen besteht, die in allen Drehstellungen der Bausteine senkrecht zu den jeweils aneinanderliegenden Verbindungsflächen einander benachbarter Bausteine verlaufen, und dass sämtliche Verbindungsflächen der Bausteine als regelmässiges Vieleck ausgebildet sind.This is achieved according to the invention in that the connecting axis consists of axis parts which run perpendicular to the respectively adjacent connecting surfaces of adjacent building blocks in all rotational positions of the building blocks, and in that all connecting surfaces of the building blocks are designed as a regular polygon.

Durch die Ausbildung der im gleichen Winkel zur Stangenlängsachse geneigten Verbindungsflächen der Bausteine als regelmässiges Vieleck werden durch deren Eckenzahl wenigstens drei derartige Relativstellungen der jeweils aneinandergrenzenden Bausteine vorbestimmt, in denen diese mit ihren gemeinsamen Verbindüngsflächen deckungsgleich aufeinanderliegen und räumlich unterschiedliche gegenseitige Winkefstellungen einnehmen. Dadurch können nicht nur ebene, sondern auch vielfach unterschiedliche räumliche Figuren von deren Stangenform bis zu vielfach verwinkelten Formen gebildet werden. Da ausserdem gemäss der Erfindung die die Verbindungsachse der Bausteine bildenden Achsteile in allen Drehstellungen senkrecht zu den jeweils aneinanderliegenden Verbindungsflächen aneinandergrenzender Bausteine bleiben, sind diese Achsteile für sämtliche durch das Verdrehen der Bausteine erzielbaren Gestalten des Spielzeugs und auch während des Verdrehens der Bausteine nicht auf Biegung oder Scherung belastet und werden auch nicht geknickt, so dass eine Überlastung der Achsteile auch beim unachtsamen Umgang mit dem Spielzeug durch Kinder vermieden ist. Eine Überlastung der Achsteile wird dadurch selbst dann vermieden, wenn die Federkraft, mit welcher die Bausteine gegeneinandergedrückt werden, gross ist, damit die einzelnen, in mannigfaltig unterschiedlicherWeise entstehenden räumlichen Figuren selbsttragend formbeständig sind.Through the formation of the connecting surfaces of the building blocks inclined at the same angle to the longitudinal axis of the blocks as a regular polygon, at least three such relative positions of the respectively adjacent building blocks are predetermined by their number of corners, in which these lie congruently with one another with their common connecting surfaces and assume spatially different mutual angular positions. As a result, not only flat, but also many different spatial figures can be formed, from their rod shape to many angled shapes. Since, in addition, according to the invention, the axis parts forming the connecting axis of the building blocks remain perpendicular to the respectively adjacent connecting surfaces of building blocks in all rotational positions, these axis parts are not subject to bending or for all shapes of toys that can be achieved by rotating the building blocks and also during the turning of the building blocks Shear stresses and are not kinked, so that overloading of the axle parts is avoided even if the toy is handled carelessly by children. Overloading of the axle parts is thereby avoided even if the spring force with which the building blocks are pressed against one another is high, so that the individual spatial figures, which arise in a variety of different ways, are self-supporting in shape.

Das erfindungsgemässe Gestaltungsspielzeug kann daher in hohem Masse zur Schulung und Weiterentwicklung der gestalterischen Fähigkeiten und des räumlichen Vorstellungsvermögens sowie zum Erlernen der Stereogeometrie verwendet werden.The inventive design toy can therefore be used for training and Further development of the creative skills and spatial imagination as well as for learning the stereo geometry can be used.

Wenngleich die beiden Verbindungsflächen der jeweiligen Bausteine voneinander verschieden sein können, solange sie regelmässig vielekkig sind und die aufeinanderliegenden Verbindungsflächen jeweils einander benachbarter Bausteine deckungsgleich ausgebildet sind, sind die beiden Verbindungsflächen jedes Bausteines vorzugsweise identisch ausgebildet, so dass alle Bausteine identische Verbindungsflächen aufweisen. Ferner können die einzelnen Bausteine unterschiedliche Formen haben.Although the two connecting surfaces of the respective building blocks can be different from one another, as long as they are regularly polygonal and the superimposed connecting surfaces of adjacent building blocks are congruent, the two connecting surfaces of each building block are preferably of identical design, so that all building blocks have identical connecting surfaces. Furthermore, the individual building blocks can have different shapes.

In der bevorzugten Ausgestaltung jedoch sind sämtliche Bausteine untereinander gleich ausgebildet. Dies ist aus dem eingangs erwähnten DE-U-7005541 an sich bekannt.In the preferred embodiment, however, all of the building blocks are designed identically to one another. This is known per se from the aforementioned DE-U-7005541.

Ferner sind die Bausteine in weiterer Ausbildung der Erfindung als gerade Prismen ausgebildet, deren Grundfläche und Deckfläche als gleichschenklige Trapeze oder gleichschenklige Dreiecke ausgebildet sind, wobei die beiden von den gleichen Schenkelseiten der Grund- und Deckfläche begrenzten Seitenflächen die Verbindungsflächen bilden und die Verbindungsflächen quadratisch ausgebildet sind.Furthermore, the modules in a further embodiment of the invention are designed as straight prisms, the base and top surface of which are designed as isosceles trapezoids or isosceles triangles, the two side surfaces delimited by the same leg sides of the base and top surface forming the connection surfaces and the connection surfaces being square .

Innerhalb eines Gestaltungsspielzeuges ist es auch möglich, bei einem Teil der prismatischen Bausteine die Grund- und Deckfläche als gleichschenklige Trapeze auszubilden, wohingegen der andere Teil der Bausteine als gleichschenklige Dreicke ausgebildete Grund- und Deckflächen aufweist. Beispielsweise können Bausteine mit trapezförmiger Grundfläche mit Bausteinen dreickiger Grundfläche abwechseln. Durch eine derartige Gestaltung der Bausteine als Trapez-oder Dreieckprismen ergeben sich aufgrund deren geometrisch einfachen Grundform sehr zahlreiche stereogeometrische Variationsmöglichkeiten in der Gestalt des erfindungsgemässen Spielzeugs.Within a design toy, it is also possible to design the base and top surface as isosceles trapezoids for some of the prismatic modules, whereas the other part of the modules has base and top surfaces designed as isosceles triangles. For example, blocks with a trapezoidal base can alternate with blocks with a triangular base. Such a design of the building blocks as trapezoidal or triangular prisms results in numerous stereogeometric variation possibilities in the shape of the toy according to the invention due to their geometrically simple basic shape.

In vorteilhafter Ausbildung weisen die Bausteine jeweils an ihrer einen Verbindungsfläche Rastvorsprünge und an ihrer anderen Verbindungsfläche Rastvertiefungen, jeweils in der Anzahl der Ecken der jeweiligen Verbindungsfläche und symmetrisch zu deren geometrischen Mittelpunkt verteilt auf. Hierdurch sind einerseits die möglichen Relativstellungen, in denen die jeweils benachbarten Bausteine deckungsgleich aufeinanderliegen, zusätzlich vorgegeben, und andererseits kann dadurch die Federkraft, mit welcher aneinandergrenzende Bausteine gegeneinander gedrückt sind, ohne Verlust der Formbeständigkeit des Spielzeugs in seinen möglichen Gestalten gering sein, so dass ein leichtgängigeres Verdrehen der Bausteine des Spielzeuges ermöglicht wird.In an advantageous embodiment, the building blocks each have locking projections on their one connecting surface and locking recesses on their other connecting surface, each in the number of corners of the respective connecting surface and distributed symmetrically to its geometric center. On the one hand, the possible relative positions in which the adjacent blocks are congruent with one another are additionally specified, and on the other hand, the spring force with which adjacent blocks are pressed against one another can be low in its possible shapes without losing the dimensional stability of the toy, so that a smooth rotation of the building blocks of the toy is made possible.

Ferner sind in weiterer Ausgestaltung der Erfindung die Bausteine jeweils als Hohlkörper ausgebildet, dessen Hohlraum im Abstand von den Verbindungsflächen des Bausteins von einer eingesetzten Deckelplatte verschlossen ist, wobei die Achsteile jeweils von einem Zapfen gebildet sind, der durch eine Bohrung im geometrischen Mittelpunkt der jeweils aufeinanderliegenden Verbindungsflächen einander benachbarter Bausteine gesteckt ist und an beiden Enden einen Kopf aufweist, wobei zwischen dem einen Kopf des Zapfens und der benachbarten, die eine Verbindungsfläche bildenden Wand des Hohlkörpers eine Druckfeder eingespannt ist. Mittels der Feder werden daher die jeweils einander benachbarten Bausteine in der Richtung des jeweiligen Achsteils gegeneinandergedrückt, so dass die Federkraft in allen möglichen Drehstellungen senkrecht zu den aufeinanderliegenden Verbindungsflächen verläuft.Furthermore, in a further embodiment of the invention, the blocks are each designed as a hollow body, the cavity of which is closed at a distance from the connecting surfaces of the block by an inserted cover plate, the axis parts each being formed by a pin which is formed by a hole in the geometric center of the one lying on top of the other Connecting surfaces of mutually adjacent building blocks is inserted and has a head at both ends, a compression spring being clamped between the one head of the pin and the adjacent wall of the hollow body which forms a connecting surface. By means of the spring, the blocks which are adjacent to one another are therefore pressed against one another in the direction of the respective axis part, so that the spring force in all possible rotational positions runs perpendicular to the connecting surfaces lying one on top of the other.

Es ist zwar an sich bekannt (CH-A-109329), bei einem Spielzeug dessen Gelenke jeweils aus einem mit zwei Köpfen versehenen Zapfen auszubilden, auf dem eine Druckfeder sitzt, durch welche die beideitig des Gelenkes aneinandergrenzenden Glieder des Spielzeuges mit ihren aneinanderliegenden Verbindungsflächen federnd gegeneinandergedrückt sind, von denen die eine auf einem den Gelenkzapfen umgebenden Kreisbogen verteilt angeordnete Rastvertiefungen, und die andere wenigstens einen mit diesen zusammenwirkenden Rastvorsprung aufweist, so dass die Glieder in mehreren Schwenkstellungen miteinander verrastbar sind. Bei diesem bekannten Spielzeug handelt es sich jedoch um eine Gliederspielzeugfigur, wie eine Gliederpuppe.It is known per se (CH-A-109329) to form the joints of a toy in each case from a pin provided with two heads, on which a compression spring is seated, by means of which the links of the toy adjoining both sides of the joint with their adjoining connecting surfaces are resilient are pressed against each other, one of which has a locking recess arranged on a circular arc surrounding the hinge pin, and the other has at least one locking projection cooperating with it, so that the links can be locked together in several pivot positions. However, this known toy is a sectional toy figure, such as a sectional doll.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles erläutert, welches in seiner Gestaltung aus der Zeichnung ersichtlich ist. In derZeichnung zeigt:

  • Fig. 1 ein Gestaltungsspielzeug gemäss der Erfindung in Form eines vierseitigen prismatischen Stabes,
  • Fig. 2 einen Teillängenschnitt des Gestaltungsspielzeuges nach Fig. 1,
  • Fig. 3 einen der Bausteine, aus denen das Gestaltungsspielzeug nach Fig. 1 zusammengesetzt ist, in perspektivischer Ansicht, und
  • Fig. 4 ein Beispiel für einen der möglichen Körper, der durch Veränderung der Drehstellung der Bausteine des Gestaltungsspielzeuges nach Fig. 1 ausgebildet werden kann.
The invention is explained below using an exemplary embodiment, which can be seen in its design from the drawing. The drawing shows:
  • 1 is a design toy according to the invention in the form of a four-sided prismatic rod,
  • 2 shows a partial length section of the design toy according to FIG. 1,
  • 3 shows one of the building blocks from which the design toy according to FIG. 1 is composed, in a perspective view, and
  • Fig. 4 shows an example of one of the possible bodies that can be formed by changing the rotational position of the building blocks of the design toy according to Fig. 1.

Wie aus Fig. 1 ersichtlich, ist das Gestaltungsspielzeug 1 in der gezeigten Ausführungsform aus identischen geraden Dreiecksprismen aufgebaut, deren Grund- und dazu parallele Deckfläche 3 gemäss Fig. 3 deckungsgleiche Dreiecke sind und von deren rechteckigen Seitenflächen zwei als quadratische Verbindungsflächen 8 ausgebildet sind, mit denen im Gestaltungsspielzeug 1 einander benachbarte Bausteine 2 aufeinanderliegen. Im Gestaltungsspielzeug 1 werden daher dessen Aussenflächen durch die Grund- und Deckflächen 3 und die dritte Seitenfläche 9 der prismatischen Bausteine 2 gebildet. Im Ausführungsbeispiel sind die Grund- und Deckfläche 3 rechtwinklige Dreiecke, so dass die Verbindungsgflächen 8 miteinander einen rechten Winkel einschliessen. Es ist jedoch auch möglich, die Grund- und Deckfläche 3 als gleichseitige Dreiekke auszubilden, so dass die Verbindungsflächen 8 einen Winkel von 60° miteinander und mit der Seitenfläche 9 einschliessen und letztere ebenfalls quadratisch ausgebildet ist. Das Gestaltungsspielzeug 1 wird insgesamt aus beispielsweise zwölf oder vierundzwanzig Bausteinen 2 zusammengesetzt.As can be seen from FIG. 1, the design toy 1 in the embodiment shown is made up of identical straight triangular prisms, the base and parallel top surfaces 3 of which are congruent triangles according to FIG. 3 and two of whose rectangular side surfaces are designed as square connecting surfaces 8 which are adjacent to each other in the design toy 1 building blocks 2. In the design toy 1, its outer surfaces are therefore formed by the base and cover surfaces 3 and the third side surface 9 of the prismatic modules 2. In the embodiment, the base and top surface 3 are right triangles, so that the connection tion surfaces 8 form a right angle with one another. However, it is also possible to design the base and top surface 3 as equilateral triangles, so that the connecting surfaces 8 form an angle of 60 ° with one another and with the side surface 9 and the latter is also square. The design toy 1 is composed of, for example, twelve or twenty-four building blocks 2.

Die einzelnen Bausteine 2 sind in einer Reihe nebeneinander mittels Achsteilen 6 miteinander verbunden, so dass sie mit ihren als regelmässiges Vieleck ausgebildeten Verbindungsflächen 8 deckungsgleich aufeinanderliegen.The individual building blocks 2 are connected in a row next to one another by means of axle parts 6, so that they lie congruently on one another with their connecting surfaces 8 designed as a regular polygon.

Aus Fig. 2 ist die Art und Weise der Verbindung der Bausteine 2 im einzelnen ersichtlich. Die Bausteine 2 sind Hohlkörper, die entlang der Seitenfläche 9 von einer eingepressten oder eingeklebten Deckelplatte 10 geschlossen sind. Die die Verbindungsflächen 8 bildenden Wände des Hohlkörpers weisen entsprechend Fig. 3 jeweils im geometrischen Mittelpunkt dieser Verbindungsflächen 8 eine Bohrung 5 auf, durch die vor dem Einsetzen der Deckelplatte 10 als Achsteil 6 ein zylindrischer Zapfen gesteckt wird, der die Drehachse zwischen den aneinandergrenzenden Bausteinen 2 bildet und an beiden Enden einen Kopf aufweist. Zwischen dem einen Kopf des Zapfens und der benachbarten Wand des Bausteins 2 ist eine als Schraubenfeder ausgebildete Druckfeder 11 eingesetzt, mittels welcher die einander benachbarten Bausteine 2 in Richtung ihres Achsteils 6 federnd gegeneinandergedrückt sind. Die Zapfen können beispielsweise als Kopfschraube mit am freien Ende aufgeschraubter Mutter oder als Niet oder dergleichen ausgebildet sein, auf denen gegebenenfalls die aus Fig. 2 ersichtlichen Unterlegscheiben sitzen. Die miteinander verbundenen Bausteine 2 können daher um einen durch den Elastizitätsmodul der Druckfeder 11 und die freie Länge des Zapfens bestimmten Abstand in Längsrichtung des Zapfens voneinander abgehoben werden.2 shows the manner in which the modules 2 are connected in detail. The building blocks 2 are hollow bodies which are closed along the side surface 9 by a pressed-in or glued-in cover plate 10. According to FIG. 3, the walls of the hollow body forming the connecting surfaces 8 each have a bore 5 in the geometric center of these connecting surfaces 8, through which a cylindrical pin is inserted as an axis part 6 before the cover plate 10 is inserted, which pin defines the axis of rotation between the adjoining components 2 forms and has a head at both ends. Between the one head of the pin and the adjacent wall of the component 2, a compression spring 11 is used, which is used as a helical spring and by means of which the adjacent components 2 are resiliently pressed against one another in the direction of their axis part 6. The pins can be designed, for example, as a cap screw with a nut screwed onto the free end, or as a rivet or the like, on which the washers shown in FIG. 2 may be seated. The interconnected modules 2 can therefore be lifted from each other by a distance determined in the longitudinal direction of the pin by the modulus of elasticity of the compression spring 11 and the free length of the pin.

Zur gegenseitigen Lagefixierung der Bausteine 2 sind entsprechend Fig. 3 an der einen Verbindungsfläche 8 des Bausteins 2 im Quadrat angeordnete Rastvorsprünge 4, und an der anderen Verbindungsfläche 8 ebenfalls im Quadrat angeordnete Rastlöcher oder Rastvertiefungen 7 jeweils in der gleichen Relativposition und Abmessung ausgebildet. Die zylindrischen oder kegelstumpfförmigen oder kugeligen Rastvorsprünge 4 haben eine Höhe von einigen Zehntel-Millimetern. Im zusammengebauten Zustand werden daher die einander benachbarten Bausteine 2 unter dem Druck der Druckfeder 11 in jeder der Drehlagen, in welcher die einander benachbarten Verbindungsflächen 8 der Bausteine 2 deckungsgleich aufeinanderliegen, durch Eingreifen der Rastvorsprünge 4 des einen Bausteins 2 in die Rastvertiefungen 7 des benachbarten Bausteins 2 verrastet gehalten.To mutually fix the blocks 2, according to FIG. 3, locking projections 4 arranged in a square on one connecting surface 8 of the module 2, and locking holes or recesses 7 also arranged in a square on the other connecting surface 8 are each formed in the same relative position and dimension. The cylindrical or frustoconical or spherical locking projections 4 have a height of a few tenths of a millimeter. In the assembled state, the mutually adjacent modules 2 are therefore under the pressure of the compression spring 11 in each of the rotational positions, in which the adjacent connecting surfaces 8 of the modules 2 are congruent with one another, by engaging the locking projections 4 of the one module 2 in the latching recesses 7 of the adjacent module 2 held locked.

Wenn man also den einen Baustein 2 gegen den benachbarten Baustein 2 verdrehen will, wird er von diesem erst etwas abgehoben, bis die Rastvorsprünge 4 aus den Rastvertiefungen 7 freigekommen sind, wonach die Verdrehung um das zapfenförmige Achsteil 6 erfolgt. Da die Verbindungsflächen 8 der Bausteine 2 in einem Winkel zueinander verlaufen, ändert sich durch das gegenseitige Verdrehen einander benachbarter Bausteine 2 deren gegenseitige Winkellage. Durch das Vorhandensein der Rastvorsprünge 4 und der Rastvertiefungen 7 ist dafür gesorgt, dass die Bausteine des Gestaltungsspielzeugs 1 im wesentlichen nur schrittweise nacheinander verdreht werden können.So if you want to twist one block 2 against the adjacent block 2, it is only lifted up a little by this until the locking projections 4 are released from the locking recesses 7, after which the rotation takes place about the peg-shaped axis part 6. Since the connecting surfaces 8 of the modules 2 run at an angle to one another, the mutual angular position changes due to the mutual rotation of adjacent modules 2. The presence of the locking projections 4 and the locking recesses 7 ensures that the building blocks of the design toy 1 can essentially only be rotated one after the other step by step.

Das Gestaltungsspielzeug 1 ist beispielsweise aus zwölf oder vierundzwanzig Bausteinen zusammengesetzt, so dass sich eine in Abhängigkeit von ihrer Anzahl und den durch die Anzahl der Ecken der von den Verbindungsflächen 8 gebildeten regelmässigen Vielecke bestimmte Anzahl von möglichen Gestaltungsvariationen ergibt. Eine derselben ist aus Fig. 4 ersichtlich.The design toy 1 is composed, for example, of twelve or twenty-four building blocks, so that there is a number of possible design variations depending on their number and the number of possible design variations determined by the number of corners of the regular polygons formed by the connecting surfaces 8. One of them is from Fi g. 4 can be seen.

Die Bausteine 2 des Gestaltungsspielzeuges 1 können mittels Spritzguss aus Kunststoff ausgebildet werden und farbig sein.The building blocks 2 of the design toy 1 can be injection molded from plastic and colored.

Der Querschnittsumriss der Bausteine 2 braucht nicht wie dargestellt, quadratisch zu sein. Der Querschnittsumriss der Bausteine 2 kann auch z.B. sechseckig oder achteckig sein, derart, dass die im Winkel zueinander verlaufenden beiden Verbindungsflächen 8 die Form eines regelmässigen Achtecks bzw. Sechsecks aufweisen. In der Seitenansicht in Richtung parallel zu den Verbindungsflächen 8 ist die Grund- und Deckfläche 3 der Bausteine vorzugsweise ein gleichschenkliges Dreieck oder Trapez oder ein Parallelogramm.The cross-sectional outline of the building blocks 2 need not be square as shown. The cross-sectional outline of the building blocks 2 can also be e.g. be hexagonal or octagonal, in such a way that the two connecting surfaces 8 running at an angle to one another have the shape of a regular octagon or hexagon. In the side view in the direction parallel to the connecting surfaces 8, the base and top surface 3 of the blocks is preferably an isosceles triangle or trapezoid or a parallelogram.

Im letzten Fall verlaufen die Verbindungsflächen 8 entsprechend dem einen Seitenpaar des Parallelogramms zwar nicht im Winkel zueinander, sondern parallel. Da aber auch in diesem Fall die Verbindungsflächen 8 in einem von 90° abweichenden Winkel zu dem anderen Seitenpaar des Parallelogramms verlaufen, wird die gegenseitige Winkelstellung einander benachbarter Bausteine 2 durch deren gegenseitige Verdrehung ebenfalls geändert.In the latter case, the connecting surfaces 8 do not run at an angle to one another, but parallel, in accordance with the one side pair of the parallelogram. However, since the connecting surfaces 8 also run in this case at an angle deviating from 90 ° to the other side pair of the parallelogram, the mutual angular position of mutually adjacent modules 2 is also changed by their mutual rotation.
