Abstract

Toy building blocks with a coupling element projecting at one end face can be connected to adjacent toy building blocks via corresponding openings. For this purpose, the coupling element is inserted in an opening and rotated by 90 DEG . <??>In order to obtain a safeguard against rotation in the region of such a connection, at least one elevated surface is constructed to the side of the coupling element on the outside surface, at which the coupling element projects, which elevated surface can engage on the opening of an adjacent toy building block to be connected. <IMAGE>

Description

Die Erfindung betrifft ein Spielbauelement mit einem Verbindungszapfen gemäß der Gattung des Hauptanspruchs.The invention relates to a toy component with a connecting pin according to the preamble of the main claim.

Aus der DE-OS 20 56 230 ist ein Spielbauelement bekannt, welches Baustein eines Spielbaukastens ist. Dieses bekannte Spielbauelement besitzt an einer Stirnseite einen Verbindungszapfen, der in eine im wesentlichen rechteckige Öffnung eines benachbarten Bauelements einsetzbar und durch Drehen um 90° verriegelbar ist. Das Spielbauelement selbst besitzt ebenfalls an zwei Längsseiten derartige Öffnungen, in die ein Verbindungszapfen einsetzbar ist. Der Verbindungszapfen weist an seinem abstehenden Ende zwei einander gegenüberliegende Vorsprünge auf, die den Verbindungszapfen nach dem Einsetzen in eine längliche Öffnung und nach Verdrehen um 90° gegen Herausrutschen aus der Öffnung sichern.From DE-OS 20 56 230 a toy building element is known, which is a building block of a toy building set. This known toy component has a connecting pin on one end face, which can be inserted into a substantially rectangular opening of an adjacent component and can be locked by turning through 90 °. The toy component itself likewise has openings of this type on two longitudinal sides, into which a connecting pin can be inserted. The connecting pin has at its protruding end two mutually opposite projections which secure the connecting pin against slipping out of the opening after insertion into an elongated opening and after being rotated through 90 °.

Die Schaftlänge bis zum Ansatz der Vorsprünge kann geringfügig kleiner sein als die Wandstärke des zu verbindenden benachbarten Bauelements im Bereich dessen Öffnung, um eine gewisse Klemmwirkung zu erzielen. Eine solche Klemmwirkung kann insbesondere bei Spielbausteinen aus Kunststoff aufgrund dessen Elastizität erhalten werden, jedoch stellt diese Klemmwirkung oftmals eine zu geringe Sicherung gegen unbeabsichtigtes Verdrehen dar.The shaft length up to the base of the projections can be slightly smaller than the wall thickness of the adjacent component to be connected in the region of its opening in order to achieve a certain clamping effect. Such a clamping effect can be obtained in particular in the case of plastic toy building blocks due to its elasticity, but this clamping effect often represents insufficient protection against unintentional twisting.

Der Erfindung liegt die Aufgabe zugrunde, eine Verdrehsicherung für Spielbauelemente im Bereich des Verbindungszapfens zu schaffen.The invention has for its object to provide an anti-rotation device for toy components in the area of the connecting pin.

Die Lösung dieser Aufgabe wird bei einem Spielbauelement der eingangs genannten Gattung durch die im kennzeichnenden Teil des Hauptanspruchs angegebenen Merkmale erhalten. Durch eine an der Außenfläche neben dem Verbindungszapfen geringfügig überstehende Erhebung wird eine Verdrehsicherung erhalten, die in die Öffnung eines benachbarten Bauelements lösbar einrasten kann. Die länglichen Öffnungen stehen nämlich am Schaft, der im wesentlichen einen kreisförmigen Querschnitt hat, seitlich über, so daß nachdem der Verbindungszapfen um 90° gedreht ist die Erhebung in den überstehenden bzw. freien Teil der Öffnung eingreift. Die Erhebung ist vorzugsweise als Fläche ausgebildet, die in ihrer Form an den überstehenden Öffnungsteil angepaßt ist. Die Erhebung paßt somit exakt in den freien Öffnungsteil und bildet damit eine entsprechend exakte Verdrehsicherung.The solution to this problem is obtained in a toy component of the type mentioned by the features specified in the characterizing part of the main claim. A protrusion against rotation is obtained by a protrusion slightly protruding on the outer surface next to the connecting pin, which can be detachably latched into the opening of an adjacent component. The elongated openings are namely on Shaft, which has a substantially circular cross section, laterally over, so that after the connecting pin is rotated by 90 °, the elevation engages in the protruding or free part of the opening. The elevation is preferably designed as a surface whose shape is adapted to the projecting opening part. The elevation thus fits exactly into the free opening part and thus forms a correspondingly precise anti-rotation device.

Die Erhebungen sind vorzugsweise symmetrisch zu beiden Seiten des Schaftes angeordnete erhöhte Flächen, jedoch sind auch andere Erhebungen geeignet. Eine gute Verdrehsicherung wurde mit erhöhten Flächen erzielt, die gegenüber der Außenfläche um 0,2 bis 0,4 mm überstanden.The elevations are preferably raised surfaces arranged symmetrically on both sides of the shaft, but other elevations are also suitable. A good anti-twist protection was achieved with raised surfaces that protruded 0.2 to 0.4 mm from the outer surface.

Die Vorsprünge, welche dem Verbindungszapfen eine T-Form geben, gehen vorzugsweise über jeweils eine geneigte Fläche in den Schaft über. Die geneigte Fläche hat den Vorteil, daß die gewünschte Klemmwirkung zwischen Verbindungszapfen und benachbartem Bauelement am Ansatz der geneigten Fläche auftritt und somit vorhandene Fertigungstoleranzen im Hinblick auf die auftretenden Klemmkräfte weniger problematisch sind.The projections, which give the connecting pin a T-shape, preferably merge into the shaft over an inclined surface. The inclined surface has the advantage that the desired clamping effect between the connecting pin and the adjacent component occurs at the base of the inclined surface and thus existing manufacturing tolerances are less problematic with regard to the clamping forces that occur.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the subclaims.

Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.The invention is explained below with reference to the drawing.

Es zeigen:

  • Figur 1 die Seitenansicht eines Spielbauelements mit Verbindungszapfen, der in ein benachbartes Bauelement eingreift,
  • Figur 2 den Längsschnitt entlang der Schnittlinie A-B des in Figur 1 dargestellten Spielbauelements mit Verbindungszapfen und
  • Figur 3 die Draufsicht des in Figur 1 dargestellten Bauelements mit Verbindungszapfen.
Show it:
  • FIG. 1 shows the side view of a toy component with a connecting pin which engages in an adjacent component,
  • 2 shows the longitudinal section along the section line AB of the toy component shown in Figure 1 with connecting pin and
  • 3 shows the top view of the component shown in FIG. 1 with connecting pins.

Das in Figur 1 dargestellte Spielbauelement besitzt an seiner oberen Außenfläche 1 einen senkrecht abstehenden Verbindungszapfen 2 mit seitlichen Vorsprüngen 3, 4. Die Vorsprünge 3, 4 gehen über geneigte Flächen 5, 6 in den Schaft 7 über, dessen Querschnitt im wesentlichen kreisförmig ist.The toy component shown in FIG. 1 has on its upper outer surface 1 a vertically projecting connecting pin 2 with lateral projections 3, 4. The projections 3, 4 pass over inclined surfaces 5, 6 into the shaft 7, the cross section of which is essentially circular.

An der Außenfläche 1 ist zu beiden Seiten des Schaftes 7 eine flächige Erhebung 8 ausgebildet, die in eine längliche Öffnung 9 eines benachbarten Spielbauelements 10 eingreift. Die Öffnung 9 hat dabei die Form der Öffnung 11 wie sie an der sichtbaren Stirnseite des Spielbauelements 12 vorgesehen ist.On the outer surface 1, a flat elevation 8 is formed on both sides of the shaft 7, which engages in an elongated opening 9 of an adjacent toy component 10. The opening 9 has the shape of the opening 11 as it is provided on the visible end face of the toy component 12.

In Figur 2, die den Querschnitt durch das Spielbauelement 12 entlang der Schnittlinie A-B zeigt, ist die angeformte Erhebung 8 zu beiden Seiten des Schaftes 7 erkennbar.In Figure 2, which shows the cross section through the toy component 12 along the section line A-B, the molded elevation 8 can be seen on both sides of the shaft 7.

Die Draufsicht gemäß Figur 3 zeigt, daß die Erhebung 8 eine rechteckförmige Fläche ist, die an die Kontur der Öffnungen 9, 11 angepaßt ist. Die Erhebung 8 greift somit exakt in die seitlich am Zapfen 7 freibleibenden Öffnungsbereiche der Öffnung 9 ein, die den Öffnungsbereichen 13, 14 der Öffnung 11 entsprechen.The top view according to FIG. 3 shows that the elevation 8 is a rectangular surface which is adapted to the contour of the openings 9, 11. The elevation 8 thus engages exactly in the opening areas of the opening 9 which are left free on the pin 7 and which correspond to the opening areas 13, 14 of the opening 11.

Die Lage der flächigen Erhebungen 8 ist um 90° gegenüber der Längsachse 15 versetzt, die die gemeinsame Mittellinie der Vorsprünge 3, 4 bildet. Dadurch rastet die Fläche 8 erst nach Einsetzen des Verbindungszapfens 2 in eine Öffnung 9 und nach anschließendem Verdrehen um 90° in die Bereiche 13, 14 ein.The position of the flat elevations 8 is offset by 90 ° with respect to the longitudinal axis 15, which forms the common center line of the projections 3, 4. As a result, the surface 8 only snaps into the areas 13, 14 after the connecting pin 2 has been inserted into an opening 9 and then rotated through 90 °.
