Fasteners interconnect the two parts of the frame in a fixed but freely rotatable way. One part (2) of the frame is secured to the car body (1) and the other part (5) of the frame is separated from the car body (1).

Description

Die vorliegende Erfindung betrifft ein Fahrspielzeug mit eigenmotorischem Antrieb mit auf der Fahrbahn schleifenden Stromabgreifern, insbesondere Spielzeugauto für Rennbahnspielanlagen, mit einem vorderen Chassisteil mit Vorderrädern und einem von diesem getrennten hinteren Chassisteil mit Hinterrädern, sowie mit einem oberhalb der beiden Chassisteile angeordneten Fahrzeugaufbau, an dem das hintere Chassisteil vom Fahrzeugaufbau getrennt angeordnet ist, wobei ferne im Bereich zwischen den Vorder- und Hinterrädern eine zur Fahrzeuglängsachse parallel ausgerichtete Schwenkachse zur Ermöglichung von Schwenkbewegungen der beiden Chassisteile relativ zueinander vorgesehen ist und wobei ein Antriebsmotor am hinteren Chassisteil angeordnet ist.The present invention relates to a driving toy with its own motor drive with current taps that grind on the road, in particular a toy car for racetrack play facilities, with a front chassis part with front wheels and a rear chassis part with rear wheels separated from this, and with a vehicle structure arranged above the two chassis parts, on which the rear chassis part is arranged separately from the vehicle body, a swivel axis parallel to the longitudinal axis of the vehicle being provided in the region between the front and rear wheels to enable swiveling movements of the two chassis parts relative to one another, and a drive motor being arranged on the rear chassis part.

Ein derartiges Fahrspielzeug ist in der US-A-2,703,534 beschrieben. Das hintere Chassisteil dieses bekannten Fahrspielzeugs weist an dessen vorderem Ende eine horizontale Bohrung auf, durch die eine mit dem vorderen Chassisteil des Fahrspielzeugs fest verbundene Stange drehbar hindurchverläuft. Für das Abstützen des freien Endes der Stange ist offensichtlich eine Art von Splint oder dergleichen vorgesehen, welche durch eine Querbohrung am Endbereich der Stange hindurchgesteckt werden muß. Desweiteren sind die Stromabgreifer dieses bekannten Fahrspielzeugs am hinteren Chassisteil angeordnet, wodurch aufgrund der Verschwenkbarkeit der Chassisteile zueinander insbesondere in Kurvenbereichen und bei hoher Geschwindigkeit es zu eine Unterbrechung der Stromabnahme kommen kann, nämlich dann, wenn das hintere Chassisteil sich aufgrund der Fliehkraft in einer Schräglage befindet.Such a driving toy is described in US-A-2,703,534. The rear chassis part of this known driving toy has at its front end a horizontal bore through which a rod, which is fixedly connected to the front chassis part of the driving toy, rotates. For supporting the free end of the rod, a type of cotter pin or the like is obviously provided, which must be inserted through a transverse bore at the end region of the rod. Furthermore, the current taps of this known toy are arranged on the rear chassis part, which, due to the pivotability of the chassis parts relative to one another, in particular in corner areas and at high speed, can lead to an interruption in the current draw, namely when the rear chassis part is in an inclined position due to the centrifugal force .

Die Aufgabe der vorliegenden Erfindung besteht darin, ein verbessertes Fahrspielzeug der gattungsgemäßen Art zu schaffen, welches einerseits eine sichere Verbindung von vorderem mit hinterem Chassisteil gewährleistet, zum anderen in fertigungstechnischer Hinsicht besonders einfach herstellbar sein soll und darüber hinaus einen optimalen Stromabriff vor allem in Kurvenfahrten bei hoher Geschwindigkeit gewährleisten soll.The object of the present invention is to provide an improved driving toy of the generic type which, on the one hand, ensures a secure connection from the front to the rear chassis part, on the other hand, is to be particularly simple to manufacture in terms of production technology and, moreover, provides optimal current tapping especially when cornering to ensure high speed.

Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 1 dadurch gelöst, daß die Schwenkachse mit ihrem einen Ende an dem rückwärtigen Chassisteil festgelegt ist und mit ihrem gegenüberliegenden Ende in eine an dem vorderen Chassisteil angebrachte, hülsenförmige Halterung frei drehbar eingreift, wobei dieses drehbr gehaltene Ende de Schwenkachse einen Bund aufweist, der als Widerlager den frei drehbar gehaltenen vorderen Chassisteil zwischen dem festgelegten, hinteren Chassisteil und dem Bund unverschieblich stützt und das abschwenkbare vordere Chassisteil die Stromabgreifer trägt.This object is achieved in connection with the features of the preamble of claim 1 in that the pivot axis is fixed at one end to the rear chassis part and with its opposite end freely rotatably engages in a sleeve-shaped holder attached to the front chassis part, this rotationally held end of the pivot axis has a collar which, as an abutment, supports the freely rotatable front chassis part between the fixed, rear chassis part and the collar and the swiveling front chassis part carries the current collectors.

Das erfindungsgemäße Fahrspielzeug gewährleistet eine gutgesicherte Unverschiebbarkeit der beiden Chassisteile in Richtung der Fahrzeuglängsachse insbesondere kann ein axiales Spiel von vorderem zu hinterem Chassisteil, welches zu einer Berührung von vorderem und hinterem Chassisteil führen kann und dadurch die Verschwenkbarkeit der beiden Chassisteile zueinander empfindlich behindern kann, vorteilhaft ausgeschlossen werden. Zudem ergibt sich eine im Vergleich zu dem Stand der Technik wesentlich vereinfachte bzw. erleichterte Montage dadurch, daß auf ein Einziehen des Splints zur Sicherung de beiden Chassisteile vollkommen verzichtet werden kann. Insofern ist das erfindungsgemäße Fahrspielzeug auch fertigungstechnisch vorteilhaft. Die Anordnung der Stromabgreifer am vorderen Chassisteil in Kombination zur Verschwenkbarkeit der beiden Chassisteile zueinander bewirkt eine wesentliche Verbesserung des Stromabgriffs insbesondere in Kurven bei hoher Fahrzeuggeschwindigkeit.The driving toy according to the invention ensures a well-secured immovability of the two chassis parts in the direction of the longitudinal axis of the vehicle. In particular, an axial play from the front to the rear chassis part, which can lead to the front and rear chassis parts coming into contact and thereby severely impeding the pivoting of the two chassis parts relative to one another, can advantageously be excluded will. In addition, compared to the prior art, assembly is significantly simplified or facilitated by the fact that retraction of the split pin to secure the two chassis parts can be completely dispensed with. In this respect, the driving toy according to the invention is also advantageous in terms of production technology. The arrangement of the current taps on the front chassis part in combination with the pivotability of the two chassis parts relative to one another brings about a significant improvement in current tapping, particularly in curves at high vehicle speeds.

Zweckmäßiger Weise is vorgesehen, daß die gemeinsame Trennebene der beiden Chassisteile in eine Ebene hinter den Vorderrädern liegt.It is expediently provided that the common parting plane of the two chassis parts lies in a plane behind the front wheels.

Eine weitere zweckmäßige Ausgestaltung des erfindungsgemäßen Fahrspielzeugs ist dadurch gekennzeichnet, daß das eine festgelegte Ende der Schwenkachse mittels eine ersten Klemmschelle an dem hinteren Chassisteil festgelegt ist, während das gegenüberliegende, drehbar gehaltene Ende der Schwenkachse in einer zweiten, mit dem vorderen Chassisteil verbundenen Klemmschelle in der Art eine Gelenkhülse gelagert ist. Diese Ausgestaltung besitzt den Vorteil einer einfachen aber sicheren Befestigungsart. Die Klemmschelle kann zur Schaffung leicht gängiger Abkippungen die Schwenkachse mit geringem Spiel umfassen.Another expedient embodiment of the toy vehicle according to the invention is characterized in that the one fixed end of the pivot axis is fixed by means of a first clamp on the rear chassis part, while the opposite, rotatably held end of the pivot axis in a second clamp connected to the front chassis part in the Art a joint sleeve is stored. This configuration has the advantage of a simple but secure type of attachment. The clamp can encompass the swivel axis with little play to create easy tipping.
