Der in Fig. 1 gezeigte Spielzeug-Traktor 1 ist durch eine Kupplungseinrichtung 2 mit einem landwirtschaftlichen Spielfahrzeug-Anhänger 3 lösbar verbunden. Die Kupplungseinrichtung 2 besteht aus einer mit dem Spielzeug-Traktor 1 verbundenen Anhängerkupplung, die einen Geräteadapter 4 aufweist, und einem Anschlußstück 5, das mit der Deichsel 6 des Spielzeug-Anhängers 3 verbunden ist.The in Fig. 1 shown toy tractor 1 is detachably connected by a coupling device 2 with a rural toy vehicle trailer 3. The coupling device 2 consists of a connected to the toy tractor 1 trailer hitch, which has a device adapter 4, and a connector 5, which is connected to the drawbar 6 of the toy trailer 3.

Der Geräteadapter 4 weist eine Gelenkaufnahme 7 und eine Festaufnahme 8 auf. Die Gelenkaufnahme 7 besteht aus einer oberen Gelenkzunge 9, die eine Durchgangsöffnung 10 aufweist, und einer unteren Gelenkzunge 11, die ebenfalls eine Durchgangsöffnung 12 aufweist. Die Gelenkzungen 9, 11 weisen im Fahrzeug-längsrichtung nach hinten. Ihre Durchgangsöffnungen 10, 12 bilden eine Kugelgelenkaufnahme. Die Fahrzeug-Längsrichtung ist in der Zeichnung mit x bezeichnet, wobei die positive x-Richtung nach vorne zeigt. Die y-Richtung weist in einer horizontalen Ebene nach links, die z-Richtung weist vertikal nach oben.The device adapter 4 has a joint receptacle 7 and a fixed receptacle 8. The joint receptacle 7 consists of an upper hinge tongue 9, which has a passage opening 10, and a lower hinge tongue 11, which likewise has a passage opening 12. The pivot tongues 9, 11 point in the vehicle longitudinal direction to the rear. Your through holes 10, 12 form a ball joint receptacle. The vehicle longitudinal direction is designated x in the drawing, with the positive x direction pointing forward. The y-direction points to the left in a horizontal plane, the z-direction points vertically upward.

Die Festaufnahme 8 ist in Fahrtrichtung x vor der Gelenkaufnahme 7 angeordnet. Sie ist der Gelenkaufnahme 7 benachbart und halbzylinderförmig ausgestaltet, wobei die Achse des Halbzylinders in Fahrzeug-Querrichtung, also in y-Richtung, verläuft.The fixed receptacle 8 is arranged in the direction of travel x in front of the joint receptacle 7. It is the joint seat 7 adjacent and designed semi-cylindrical, wherein the axis of the half-cylinder in the vehicle transverse direction, ie in the y-direction, runs.

Das Anschlußstück 5 weist einen Gelenkteil 13 und einen Aufnahmeteil 14 auf. Der Gelenkteil 13 besteht aus einer oberen Teil-Kugelfläche 15 und einer unteren Teil-Kugelfläche 16. Der Aufnahmeteil 14 ist halbzylinderförmig ausgestaltet. Die Achse des Halbzylinders verläuft in horizontaler Querrichtung, also in y-Richtung.The connecting piece 5 has a hinge part 13 and a receiving part 14. The joint part 13 consists of an upper part spherical surface 15 and a lower part spherical surface 16. The receiving part 14 is designed semi-cylindrical. The axis of the half-cylinder runs in the horizontal transverse direction, ie in the y-direction.

Im gekuppelten Zustand, der in Fig. 5 gezeigt ist, liegen die Teil-Kugelflächen 15, 16 des Gelenkteils 13 in den Durchgangsöffnungen 10, 12 der Gelenkzungen 9, 11 und liegt der halbzylinderförmige Aufnahmeteil 14 in der halbzylinderförmigen Festaufnahme 8. Das Anschlußstück 5 ist auf diese Weise fest mit dem Geräteadapter 4 verbunden. Eine Relativbewegung zwischen dem Anschlußstück 5 und dem Geräteadapter 4 ist nicht möglich. Das Anschlußstück 5 weist gegenüber dem Geräteadapter 4 keinen Freiheitsgrad (Bewegungs-Freiheitsgrad) auf. Eine Drehbewegung um die x-Achse, die y-Achse und die z-Achse wird durch den halbzylinderförmigen Aufnahmeteil 14, der in der halbzylinderförmigen Festaufnahme 8 liegt, verhindert.In the coupled state, the in Fig. 5 is shown, the partial spherical surfaces 15, 16 of the joint part 13 in the through holes 10, 12 of the pivot tongues 9, 11 and is the semi-cylindrical receiving part 14 in the semi-cylindrical retainer 8. The connector 5 is fixed in this way with the device adapter 4 connected. A relative movement between the connector 5 and the device adapter 4 is not possible. The connector 5 has over the device adapter 4 no degree of freedom (freedom of movement) on. A rotational movement about the x-axis, the y-axis and the z-axis is prevented by the semi-cylindrical receiving part 14 which lies in the semi-cylindrical retainer 8.

Der in Fig. 2 gezeigte Spielzeug-Lastwagenanhänger 17 umfaßt eine Deichsel 18, an deren vorderem Ende sich ein Anschlußstück befindet, das aus einer ein Kugelgelenk bildenden Kugel 19 besteht. Die Kugel 19 ist derart bemessen, daß sie in gleicher Weise wie die Teil-Kugelflächen 15, 16 des Gelenkteils 13 des Anschlußstücks 5 in den Durchgangsöffnungen 10, 12 der Gelenkzungen 9, 11 des Geräteadapters 4 zu liegen kommen können. Da das Anschlußstück des Spielzeug-Lastwagenanhängers 17 kein Aufnahmeteil aufweist, sondern lediglich aus einem Gelenkteil besteht, nämlich aus der ein Kugelgelenk bildenden Kugel 19, hat dieses Anschlußstück in dem Geräteadapter 4 Bewegungsmöglichkeiten um sämtliche Achsen, also sowohl um die in Fahrzeug-Längsrichtung weisende x-Achse, um die in horizontaler Fahrzeug-Querrichtung weisende y-Achse und um die in vertikale Richtung weisende z-Achse. Der Spielzeug-Lastwagenanhänger 17 hat demnach drei Freiheitsgrade.The in Fig. 2 shown toy truck trailer 17 comprises a drawbar 18, at the front end there is a fitting which consists of a ball joint forming a ball 19. The ball 19 is dimensioned such that they can come to rest in the same manner as the partial spherical surfaces 15, 16 of the joint part 13 of the connecting piece 5 in the through holes 10, 12 of the pivot tongues 9, 11 of the device adapter 4. Since the connector of the toy truck trailer 17 has no receiving part, but only consists of a hinge part, namely from the ball joint forming a ball 19, this connector has in the device adapter 4 movement possibilities to all axes, ie both the x-direction in the vehicle longitudinal x -Axis, about the y-axis pointing in the horizontal vehicle transverse direction and about the z-axis pointing in the vertical direction. The toy truck trailer 17 thus has three degrees of freedom.

Es ist möglich, die Kugel 19 mit einem halbkugelförmigen Aufnahmeteil zu versehen (in der Zeichnung nicht dargestellt), das mit der Kugel 19 verbunden ist und der Kugel 19 in x-Richtung benachbart ist. Dieses halbkugelförmige Aufnahmeteil liegt in dem mittleren Bereich der halbzylinderförmigen Festaufnahme 8. Durch das halbkugelförmige Aufnahmeteil wird eine Drehung des mit der Deichsel 18 verbundenen Anschlußstücks um die y-Achse verhindert. Eine Drehung um die x-Achse und um die z-Achse sind allerdings nach wie vor möglich. In diesem Fall hat der Anhänger zwei Freiheitsgrade.It is possible to provide the ball 19 with a hemispherical receiving part (not shown in the drawing), which is connected to the ball 19 and the ball 19 is adjacent in the x-direction. This hemispherical receiving part is located in the central region of the semi-cylindrical retainer 8. The hemispherical receiving part prevents rotation of the connecting piece connected to the drawbar 18 about the y-axis. However, rotation around the x-axis and around the z-axis is still possible. In this case, the trailer has two degrees of freedom.

Die Gelenkzungen 9, 11 weisen in ihren einander gegenüberliegenden Bereichen Einführschrägen 20, 21 auf, durch die das elastische Aufweiten der Gelenkzungen 9, 11 beim Einführen des Anschlußstücks 5 bzw. der Kugel 19 erleichtert wird.The pivot tongues 9, 11 have in their opposite areas insertion bevels 20, 21, through which the elastic expansion of the pivot tongues 9, 11 during insertion of the connecting piece 5 and the ball 19 is facilitated.

An dem Anschlußstück 5 ist eine obere Abstützrippe 22 vorgesehen, die in x-Richtung absteht und deren vorderes Ende 23 im eingekuppelten Zustand an einer Abschlußplatte 24' des Geräteadapters 4 anliegt. Durch die obere Abstützrippe 22 wird ein Anschlag beim Einkuppeln gebildet.At the connecting piece 5, an upper Abstützrippe 22 is provided which projects in the x-direction and the front end 23 rests in the engaged state on a closure plate 24 'of the device adapter 4. By the upper support rib 22, a stop is formed during engagement.

Ferner weist das Anschlußstück 5 eine linke Abstützrippe 24 und eine rechte Abstützrippe 25 auf, die in x-Richtung verlaufen und an denen Stufen 26, 27 vorgesehen sind, die im eingekuppelten Zustand an der Abschlußplatte 24' des Geräteadapters 4 anliegen.Further, the connector 5 has a left Abstützrippe 24 and a right Abstützrippe 25, which extend in the x direction and at which stages 26, 27 are provided, which abut in the engaged state on the end plate 24 'of the device adapter 4.

Die Verbindung zwischen dem Anschlußstück 5 und dem Geräteadapter 4 kann gewaltsam gelöst werden, und zwar dadurch, daß diese beiden Teile auseinandergezogen werden. Das Herstellen und das Lösen der Verbindung erfolgt also durch Einstecken und Auseinanderziehen.The connection between the connector 5 and the device adapter 4 can be solved by force, namely, that these two parts are pulled apart. The manufacture and release of the connection thus takes place by plugging in and pulling apart.

Der Geräteadapter 4 eignet sich sowohl zur Verbindung mit einem Anschlußstück 5, das einem Gelenkteil 13 und einen Aufnahmeteil 14 aufweist, als auch zur Verbindung mit einem Kugelgelenk, das aus einer Kugel 19 besteht. Dementsprechend können verschiedene Anschiußstücke im Zusammenwirken mit einem einzigen Geräteadapter verwendet werden, so daß die Vielfalt der Spielmöglichkeiten erhöht wird. Durch die Erfindung wird es möglich, ein Spielfahrzeug unter Verwendung desselben Geräteadapters mit verschiedenen Spielfahrzeug-Anhängern zu verbinden, die gegenüber dem Spielfahrzeug auf verschiedene Weise beweglich sind: durch ein Kugelgelenk, das drei Freiheitsgrade aufweist, oder durch ein Anschlußstück mit zwei, einem oder keinem Freiheitsgrad. Für alle Bewegungsmöglichkeiten genügt ein und derselbe Gerätedapter.The device adapter 4 is suitable both for connection to a connecting piece 5, which has a joint part 13 and a receiving part 14, as well as for connection to a ball joint, which consists of a ball 19. Accordingly, various Anschiußstücke can be used in conjunction with a single device adapter, so that the variety of game options is increased. By the invention it becomes possible to connect a toy vehicle using the same device adapter with different toy vehicle trailers, which are movable in different ways with respect to the toy vehicle: by a ball joint having three degrees of freedom, or by a fitting with two, one or none degree of freedom. For all movement possibilities one and the same device adapter suffices.
