Abstract

The building block for toy building elements has the shape of a box-type hollow body, made of plastic, which is open at one side and is fitted with primary and secondary coupling members for the purpose of building. A greater flexibility of building of the building blocks is achieved whilst reducing the material requirement and the costs of technical production. The essence of the invention consists in a novel design and novel orientation of the coupling members, the primary coupling members having a reduction in the wall thicknesses of the hollow body and a diameter which is enlarged in such a way that they can be plugged together in x and y direction with the primary coupling elements of an adjacent building block while longitudinally extending walls are provided in the interior of the hollow body, which walls have recesses in the engagement region of the primary coupling elements. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Baustein für Spielbauelemente in Form eines einseitig offenen kastenförmigen Hohlkörpers, vorzugsweise aus Kunststoff, auf dessen geschlossener Oberseite Primärkupplungselemente, aus vornehmlich im Raster nebeneinanderliegenden Hohlzapfen, vorgesehen sind, während im Innern des kastenförmigen Hohlkörpers Sekundärkupplungselemente angeordnet sind, in denen sich die Primärkupplungselemente eines aufzusteckenden zweiten Bausteines klemmend einpassen.The invention relates to a building block for toy components in the form of a box-shaped hollow body open on one side, preferably made of plastic, on the closed top of which primary coupling elements are provided, primarily of hollow pins lying next to one another in a grid, while secondary coupling elements are arranged in the interior of the box-shaped hollow body fit the primary coupling elements of a second component to be clipped on.

Derartige Bausteine sind bereits in den verschiedenartigsten Ausführungsformen bekannt, wobei sie sich im wesentlichen durch die Form und die Anordnung der Sekundärkupplungselemente im Innern des Hohlkörpers unterscheiden.Modules of this type are already known in the most varied of embodiments, and they differ essentially in the shape and arrangement of the secondary coupling elements in the interior of the hollow body.

So ist beispielsweise ein Baustein bekannt - DE-AS 1076 007; DE-OS 2242 046 - bei dem die erwähnten Sekundärkupplungselemente vorzugsweise die Form von Hohlzapfen haben.For example, a building block is known - DE-AS 1076 007; DE-OS 2242 046 - in which the mentioned secondary coupling elements preferably have the shape of hollow pins.

Sekundärkupplungselemente, die zylindrisch, kreuzförmig o..ä. ausgebildet sind, stellen praktisch einen Spezialfall derjenigen Kupplungselemente dar, die aus von Wand zu Wand verlaufenden Stegen oder dergl. bestehen, in denen dann die Zapfen der Primärkupplungselemente des aufzusteckenden zweiten Bausteines eingreifen - DE-PS 1106 222; DD-PS 30 880; DE-GM 1728 773 und DE-GM 1875 433.Secondary coupling elements that are cylindrical, cruciform or similar. are practically a special case of those coupling elements which consist of webs or the like running from wall to wall, in which the pins of the primary coupling elements of the second component to be plugged in then engage - DE-PS 1106 222; DD-PS 30 880; DE-GM 1728 773 and DE-GM 1875 433.

Besagte Stege, die auch gitterartig angeordnet sind, erfordern infolge ihrer Verbindung mit den Wänden desBausteins und der daraus resultierenden Formsteifigkeit eine außerordentliche hohe Paßgenauigkeit der zu kuppelnden Zapfen, weil sie nicht nachgiebig sind.Said webs, which are also arranged in a grid, require, because of their connection to the walls of the building block and the resulting stiffness, an extraordinarily high degree of accuracy of fit of the pins to be coupled, because they are not flexible.

Demgegenüger besteht der Vorteil der erwähnten Sekundärkupplungselemente in Form freistehenden, zylindrischer Hohlzapfen, die weder untereinander, noch mit den Wänden des Bausteines verbunden sind, darin, daß sie federnd nachgeben und so das wiederholte Verbauen und Lösen der Bausteine erleichtern.On the other hand, the advantage of the secondary coupling elements mentioned in the form of free-standing, cylindrical hollow pins, which are neither connected to one another nor to the walls of the component, is that they yield resiliently and thus facilitate repeated installation and removal of the components.

Diese Federwirkung, die eine bessere Klemmwirkung unter Berücksichtigung etwaiger geringfügiger Paßungsungenauigkeiten hervorrufen soll, wird jedoch nachteiligerweise schon dadurch beeinträchtigt, daß jeweils einem am Sekundärkupplungselement anliegenden Primärkupplungselement ein anderes Primärkupplungselement gegenüberliegt, wobei infolge der Klemmwirkung von dem einem Primärkupplungselement ein Druck gegen das Sekundärkupplungselement in Richtung des gegenüberliegenden Primärkupplungselementes ausgeübt wird. Da letzteres in entgegengesetzter Richtung gegen das Sekundärkupplungselement drückt, wird die Federwirkung praktisch aufgehoben bzw. zumindest vermindert. Dies hat zur Folge, daß entweder eine zu lockere Klemmwirkung zustande kommt, falls das erforderliche Maß der Kupplungselemente unterschritten ist, oder es tritt im anderen Falle eine zu starke Klemmwirking ein, die dann Schwierigkeiten beim Lösen der Bausteine bereitet.This spring action, which is supposed to produce a better clamping action taking into account any slight inaccuracies in fit, is disadvantageously adversely affected by the fact that a primary coupling element lying against the secondary coupling element is opposite another primary coupling element, whereby due to the clamping effect of the one primary coupling element, a pressure against the secondary coupling element in the direction of opposite primary coupling element is exercised. Since the latter presses in the opposite direction against the secondary clutch element, the spring action is practically canceled or at least reduced. The result of this is that either a too loose clamping action occurs if the required dimension of the coupling elements is undershot, or in the other case an excessively strong clamping knitting occurs, which then causes difficulties in releasing the blocks.

Diese Bausteinausführung setzt daher eine sehr hohe Paßgenauigkeit voraus, die jedoch nicht mit allen Kunststoffen erreicht werden kann.This block design therefore requires a very high degree of fit, but this cannot be achieved with all plastics.

Darüber hinaus gehen die bekannten verschiedenartigsten Ausführungen der Bausteine fast ausschließlich vom gleichen Verbinsungsprinzip aus, d.h. von einem gleichen Teilungsabstand (Raster) der Primärkupplungselemente in Längs-und Querrichtung, wobei der Mittenabstand von je vier Zapfen die Ecken eines Quadrates darstellen.In addition, the known most diverse designs of the modules are based almost exclusively on the same connection principle, i.e. of an equal pitch (grid) of the primary coupling elements in the longitudinal and transverse directions, the center distance of four pegs each representing the corners of a square.

Eine Verbauung von Bausteinen kann deshalb nur im Rahmen des den Bausteinen zugrundeliegenden Teilungsabstandes (Raster) in Längsrichtung und oder Querrichtung erfolgen. Die Möglichkeit, einen halben Teilungsabstand (halbes Raster) zu verbauen, besteht nur in Ausnahmefällen, indem die im Hohlkörper angeordneten Sekundärkupplungselemente in Form von zylindrischen Hohlzapfen selbst Primärkupplungselemente, innerhalb des Bausteins begrenzt, aufnehmen können. Diese Verbaubarkeit kann aber nie über den Baustein hinaus weitergeführt werden, da infolge der begrenzenden Wände des kastenförmigen Hohlkörpers eine Aufnahme der Primärkupplungselemente unmöglich wird.Building blocks can therefore only be installed within the framework of the pitch (grid) on which the building blocks are based in the longitudinal and / or transverse direction. The possibility of installing a half pitch (half grid) only exists in exceptional cases, since the secondary coupling elements arranged in the hollow body in the form of cylindrical hollow pins can even accommodate primary coupling elements, limited within the module. However, this installation can never be continued beyond the module, since the primary coupling elements cannot be accommodated due to the bounding walls of the box-shaped hollow body.

Ein weitere funktioneller Nachteil aller bekannten Bausteine besteht darin, daß auf Grund der maßlichen Abstimmung von Primär- und Sekundärkupplungselementen nur zwischen diesen Kupplungselementen eine Verbindung möglich ist.Another functional disadvantage of all known components is that due to the dimensional coordination of primary and secondary coupling elements, a connection is only possible between these coupling elements.

Eine Verbindung zwischen Primärkupplungselementen (Oberseite/Oberseite zweier Bausteine) ist untereinander bei keinem der bekannten Bausteine möglich, obwohl es in verschiedenen Anwendungsfällen wünschenswert wäre.A connection between primary coupling elements (top / top of two components) is not possible with each other in any of the known components, although it would be desirable in different applications.

Eine weitere Erhöhung der universellen Verbaubarkeit der Bausteine und eine weitere Variationsmöglichkeit des Spielzeuges, insbesondere hinsichtlich seines pädagogischen Wertes, ist dadurch bei Bausteinen der bekannten Art nicht gegeben. Aus der DE-PS 224 2046 ist ferner bekannt, durch das Anbringen von Ansätzen oder Rippen an den Innenwandungen des Bausteines, d.h. im Eingriffsbereich der Prmärkupplungselemente, eine gute Klemmwirkung bei gleichzeitiger Reduzierung der Wandstärken insgesamt zu erreichen. Neben der ausgezeigten, eingeschränkten Verbaubarkeit dieser Bausteine kann auch bei dieser Lösung der erwähnte Nachteil einer aufgehobenen bzw. verminderten Federwirkung freistehender, zylindrischer Hohlzapfen nicht beseitigt werden.A further increase in the universal installability of the building blocks and a further possibility of variation of the toy, in particular with regard to its educational value, is therefore not given for building blocks of the known type. From DE-PS 224 2046 is also known, by attaching lugs or ribs on the inner walls of the block, i.e. in the engagement area of the primary coupling elements to achieve a good clamping effect while reducing the overall wall thickness. In addition to the shown, restricted installation of these modules, the mentioned disadvantage of a suspended or reduced spring effect of free-standing cylindrical hollow pins cannot be eliminated with this solution either.

Der nächstliegende Stand der Technik ist in der DE-U 1857433 (entspr. DE-AS 1 202 694) offenbart. Dieser bekannte Baustein besteht aus einem von seiner Oberseite und seinen vier Seitenwänden begrenzten und an seiner Unterseite offenen kastenförmigen Hohlkörper, auf dessen geschlossener Oberseite Primärkupplungselemente in einem Raster paarweise nebeneinanderliegend angeordnet sind, wobei jedes Kupplungselement einer Ecke eines Quadrats zugeordnet ist. Die Primärkupplungselemente können quadratisch, rund oder oval ausgebildet sein und weisen entlang ihres gesamten oder teilweisen Umfangs Erhebungen oder Aussparungen auf, die mit den Sekundärkupplungselementen eines aufzustekkenden zweiten Bausteins einrastend zusammenpassen. Im Innern des Hohlkörpers sind zwei längslaufende, zueinander und zu den zwei Seitenwänden parallele Wände bzw. Stege angeordnet (wie das auch der DE-U 1728773 bekannt ist), die eine klemmende oder rastende Verbindung mit den Primärkupplungslementen eines aufzustreckenden zweiten Bausteins ermöglicht, wobei die Primärkupplungselement des zweiten Bausteines zwischen einer Seitenwand und der Längswand eingreifen.The closest prior art is disclosed in DE-U 1857433 (corresponding to DE-AS 1 202 694). This known module consists of a box-shaped hollow body delimited by its upper side and its four side walls and open on its underside, on the closed upper side of which primary coupling elements are arranged in pairs in a grid, each coupling element being assigned to a corner of a square. The primary coupling elements can be square, round or oval and have ent over their entire or partial extent on surveys or recesses which fit snugly with the secondary coupling elements of a second component to be plugged on. In the interior of the hollow body there are two longitudinal walls or webs which are parallel to each other and to the two side walls (as is also known from DE-U 1728773), which enables a clamping or latching connection with the primary coupling elements of a second component to be opened, the The primary coupling element of the second component engages between a side wall and the longitudinal wall.

Diese Lösung gestattet keine Verbauung der Bausteine innerhalb eines halben Teilungsabschnittes (Raster) sowie keine Verbindung der Primärkupplungselemente (Oberseite/Oberseite) zweier Bausteine miteinander.This solution does not allow the blocks to be installed within half a division section (grid) or the primary coupling elements (top / top) of two blocks to be connected to one another.

Eine allgemein bekannte, drucksschriftlich nicht belegbare Lösung besteht in einem Baustein in Form eines von seiner Oberseite und seinen vier Seitenwänden begrenzten und an seiner Unterseite offenen kastenförmigen Hohlkörpers, auf dessen geschlossener Oberseite Primärkupplungselemente aus in einer Reihe in einem Raster nebeneinander angeordneten zylindrischen Vollzapfen ausgebildet sind. Die Dicke der Seitenwände entspricht dabei dem halben Abstand zwischen zwei nebeneinanderliegenden Zapfen. Im Innern des Hohlkörpers sind in einem Rasterabstand in einer Reihe freistehende, zylindrische Vollzapfen angeordnet, die in den lichten Abstand zweier Zapfen der Oberseite eines aufzusteckenden zweiten Bausteines klemmend eingreifen. Auch dieser bekannte Baustein ermöglicht keine Verbindung der Primärkupplungselemente (Oberseite/Oberseite) zweier Baustiene miteinander.A generally known solution, which cannot be documented in printed form, consists in a building block in the form of a box-shaped hollow body which is delimited by its upper side and its four side walls and is open on its underside, on the closed upper side of which primary coupling elements are formed from cylindrical solid pins arranged in a row next to one another in a grid. The thickness of the side walls corresponds to half the distance between two adjacent pins. Free-standing, cylindrical solid pins are arranged in a row in the interior of the hollow body at a grid spacing and clampingly engage in the clear distance between two pins on the top of a second component to be plugged on. This known module also does not allow the primary coupling elements (top / top) of two construction elements to be connected to one another.

Außerdem erfordern diese Bausteine, wie eingangs bereits erwähnt, auf Grund ihrer hohen Formsteifigkeit eine hohe Paßgenauigkeit und somit zusätzliche Aufwendungen in der Fertigung.In addition, as already mentioned at the beginning, these building blocks require a high degree of accuracy of fit due to their high dimensional stability and thus additional expenditure in production.

Durch die Erfindung werden die ausgezeigten Nachteile ausgeräumt und bei Reduzierung des Materialeinsatzes und ökonomisch günstigen Fertigungseigenschaften ein verbesserter Baustein vorgeschlagen, der im Hinblick auf seine grössere Verbaubarkeit über höhere Gebrauchswerteigenschaften verfügt.The disadvantages shown are eliminated by the invention and, with a reduction in the use of materials and economically favorable manufacturing properties, an improved module is proposed which has higher utility properties in view of its greater ease of installation.

Der Erfindung liegt die Aufgabe zugrunde, einen Baustein der eingangs genannten Art mit neugestalteten Primär-und Sekundärkupplungselementen zu entwickeln.The invention has for its object to develop a module of the type mentioned with redesigned primary and secondary coupling elements.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 bis 4 gelöst.This object is solved by the features of claims 1 to 4.

Erfindungsgemäß besitzen die zylinderförmigen Primärkupplungselemente bei gleichzeitiger Verringerung der Wandstärke des Hohlkörpers einen in der Weise vergrößerten Durchmesser, daß sie mit den Primärkupplungselementen eines aufzusteckenden zweiten Bausteines, versetzt durch einen halben Teilungsabstand (Raster), in Längsrichtung und Querrichtung klemmend zusammensteckbar sind und die im Inneren angeordneten längsverlaufenden Wände im Eingriffsbereich der Primärkuppiungseiemente mit Ausnehmungen von Kreisabschnitten (Segmenten) derselben versehen sind.According to the invention, the cylindrical primary coupling elements with a simultaneous reduction in the wall thickness of the hollow body have an enlarged diameter in such a way that they can be clamped together in the longitudinal and transverse directions with the primary coupling elements of a second component to be plugged on, offset by half a pitch (grid), and arranged in the interior longitudinal walls in the engagement area of the primary coupling elements are provided with recesses of circular sections (segments) of the same.

Die im Innern des Bausteines vorhandenen Wände sind in einem solchen Abstand voneinander bzw. von den Bausteinwandungen angeordnet, daß sie die eingreifenden Primärkupplungselemente eines aufzusteckenden zweitein Bausteins auf Klemm- und Paßsitz im zugrundeliegenden und halben Teilungsabstand (Raster) aufnehmen können.The walls inside the module are arranged at such a distance from one another or from the module walls that they can accommodate the engaging primary coupling elements of a second module to be plugged on with a snug and snug fit in the underlying and half pitch (grid).

Ein weiteres Merkmal der Erfindung ist es, daß die Wände nur unter den Ausnehmungen, die zur Aufnahme der Kreisabschnitte (Segmente) der Primärkupplungselemente dienen, gerade ausgebildet sind, während sie zwischen en Ausnehmungen eine wellenartige Gestaltung aufweisen können. Um eine zusätzlichen Verbaubarkeit mit halbem Teilungsabstand in mindestens einer Richtung verzetztzum unteren Baustein zu erreichen, sind die Primärkupplungselemente auf der Oberseite des Bansteinsmittig in einer Reihe angeordnet, damit die Primärkupplungselemente in die Sekundärkupplungselemente eines erfindungsgemäß ausgebildeten zweiten Bausteines klemmend eingreifen.Another feature of the invention is that the walls are just formed just under the recesses that serve to receive the circular sections (segments) of the primary coupling elements, while they can have a wave-like design between the recesses. In order to achieve an additional installation with half the pitch spaced in at least one direction from the lower building block, the primary coupling elements are arranged in a row in the middle of the top of the bank so that the primary coupling elements clampingly engage the secondary coupling elements of a second building block designed according to the invention.

Gegenüber den bisher bekannten Lösungen besitzt der erfindungsgemäße Baustein olgende Vorteile:

  • Optimale Kupplungskraft infolge der Verringerung der Wandstärke des kastenförmigen Hohlkörpers in Verbindung mit der Vergrößerung des Durchmessers der Primärkupplungselemente;
  • Erweiterung der Herstellungstoleranzen durch die im Inneren des kastenförmigen Hohlkörpers neugestalteten Sekundärkupplungselemente;
  • Verringerung der Materialeinsatzmenge und der Herstellungskosten eines jeden Bausteines, was sich in der Massenproduktion besonders vorteilhaft auswirkt;
  • geringere Toleranzgrenzen zu den vergleichsweisen bekannten Bausteinen ermöglichen eine einfachere Herstellung bzw. die Verwendung von billigeren Kunststoffmaterialien (Regeneraten bzw. Substituten);
  • Verkürzung der Herstellungszeiten (Zykluszeiten des Spritzgießvorganges), insbesondere durch die Möglichkeit der dünnwandig gestalteten Wandungen des kastenförmigen Hohlkörpers;
  • universelle bzw. flexiblere Verbaubarkeit der Bausteine untereinander durch die Neugestaltung der Primär- und Sekundärstruktur im besonderen durch die elastische und federnde Wirkung der Außenwand und der Sekundärkupplungselemente sowie deren Einordnung im Hohlraum; höhere Verbaubarkeit durch volle Ausnutzung der Kupplungselemente im vollen und halben Teilungsabstand (Raster) auf der Primär und Sekundärseite sowie eine Verbaubarkeit der Primärkupplungselemente (Oberseite/Oberseite) untereinander.
The module according to the invention has the following advantages over the previously known solutions:
  • Optimal coupling force due to the reduction in the wall thickness of the box-shaped hollow body in connection with the increase in the diameter of the primary coupling elements;
  • Extension of the manufacturing tolerances by the secondary coupling elements redesigned inside the box-shaped hollow body;
  • Reduction in the amount of material used and the manufacturing costs of each component, which has a particularly advantageous effect in mass production;
  • lower tolerance limits to the comparatively known building blocks enable easier production or the use of cheaper plastic materials (regenerates or substitutes);
  • Shortening the manufacturing times (cycle times of the injection molding process), in particular through the possibility of the thin-walled walls of the box-shaped hollow body;
  • universal or more flexible installation of the modules with each other through the redesign of the primary and secondary structure, in particular through the elastic and resilient effect of the outer wall and the secondary coupling elements and their arrangement in the cavity; Higher installability due to full utilization of the coupling elements at full and half pitch (grid) on the primary and secondary side, as well as the fact that the primary coupling elements (top / top) can be installed together.

  • Fig. 9, 9a to 9b: two staggered blocks (bottom / top), which are installed at half the pitch in one direction beyond the block.

Der in Fig. 1 bis 3 dargestellte Baustein ist ein vorzugsweise aus Kunststoff hergestellter, kastenförmiger Hohlkörper 1. Dieser Hohlkörper 1 ist an der unteren Seite offen, während auf der geschlossenen oberen Seite Primärkupplungselemente in Form von kreiszylindrischen Holzapfen 2 angeordnet sind.1 to 3 is a box-shaped hollow body 1, preferably made of plastic. This hollow body 1 is open on the lower side, while primary coupling elements in the form of circular-cylindrical wooden plugs 2 are arranged on the closed upper side.

Die Außendurchmesser D der Primärkupplungselemente sind bei gleichzeitiger Reduzierung der Wandstärke t des kastenförmigen Hohlkörpers so vergrößert worden, daß die auf der Oberseite vorhandenen im Raster nebeneinanderliegenden Primärkupplungselemente, von denen vier Hohlzapfen 2 die Ecken eines Quadrat s darstellen, sowohl mit den Primärkupplungselementen eines aufzusteckenden zweiten Bausteins versetzt in einem halben Teilungsbstand R (halbes Raster) in Längs- und Querrichtung in Eingriff gebracht werden können als auch mit den Sekundärelementen eines aufzusteckenden zweiten Bausteins bündig in Eingriff gebracht werden können. Im Innern des Hohlkörpers 1 sind zwei dünnwandige gerade Längswande 3 vorgesehen, die als Sekundärkupplungselemente dienen (Fig. 4 und 5). Die Längswände 3 verlaufen parallel zur seitenwand des Bausteins und sind mit ausnehmungen 4 zur Aufnahme von Kreisabschnitten (Segmenten) der in Form von Hohlzylindern ausgebildeten Primärkupplungselementen versehen.The outer diameter D of the primary coupling elements have been increased while reducing the wall thickness t of the box-shaped hollow body in such a way that the primary coupling elements present on the top side next to one another in the grid, of which four hollow pins 2 represent the corners of a square, both with the primary coupling elements of a second component to be plugged on staggered in a half pitch R (half grid) in the longitudinal and transverse directions can be brought into engagement as well as can be brought into engagement flush with the secondary elements of a second component to be plugged on. Inside the hollow body 1, two thin-walled straight longitudinal walls 3 are provided, which serve as secondary coupling elements (FIGS. 4 and 5). The longitudinal walls 3 run parallel to the side wall of the module and are provided with recesses 4 for receiving circular sections (segments) of the primary coupling elements designed in the form of hollow cylinders.

In Fig. 6 sind die Wände 3 gemäß Ausführungsvariante unterhalb der Ausnehmungen 4 vorzugsweise gerade ausgebildet, während die verbleibenden Stege zwischen den Ausnehmungen 4 eine wellenartige Gestaltung 5 aufweisen.In FIG. 6, the walls 3 according to the embodiment variant are preferably straight below the recesses 4, while the remaining webs between the recesses 4 have a wave-like configuration 5.

Auf Grund der im kastenförmigen Hohlkörper 1 angeordneten Längswände 3 mit Ausnehmungen 4 ist, wie in Fig. 7 bis 9 gezeigt, ist die Anordnung von Primärkupplungselementen 2 mittig im halben Teilungsabstand hintereinanderliegend möglich. Diese Anordnung gestattet die Verbaubarkeit zwischen den, im kastenförmigen Hohlkörper 1 angeordneten Längswänden 3 und im halben Teilungsabstand zwischen Außenwand des kastenförmigen Hohlkörpers 1 und einer mit Ausnehmungen 4 versehenen Längswand 3, (Fig. 8a bis 9b).Due to the arranged in the box-shaped hollow body 1 longitudinal walls 3 with recesses 4, as shown in Fig. 7 to 9, the arrangement of primary coupling elements 2 in the middle at half the pitch is possible one behind the other. This arrangement allows the installation between the longitudinal walls 3 arranged in the box-shaped hollow body 1 and at half the spacing between the outer wall of the box-shaped hollow body 1 and a longitudinal wall 3 provided with recesses 4 (FIGS. 8a to 9b).
