Description

Sportfahrzeug Das bisher bekanntgewordene Sportfahrzeug, bestehend aus einem Vorderrad als Stütze für die Hände und zwei Hinterrädern, die durch Spreizen der Beine betätigt werden, hat den hllachteil, daß es beim Wenden Schwierigkeiten verursacht. Ihr Grund liegt darin, daß die durch .die Beine des Fahrers zu betätigende Achse der beiden Hinterräder in einem Stück ausgeführt ist.Sports vehicle The previously known sports vehicle, consisting from a front wheel as a support for the hands and two rear wheels that are spread apart The disadvantage of operating the legs is that it is difficult to turn caused. Their reason is that the .to be actuated by the legs of the driver Axle of the two rear wheels is made in one piece.

Beim Wenden macht bekanntlich das äußere Rad mehr Umdrehungen als das innere; ja dieses kann ganz stehenbleiben oder sogar sich rückwärts zu drehen gezwungen sein. Da beide Räder durch eine starre Achse miteinander verbunden sind, ist die Ausführung dieser beiden verschiedenen Bewegungen eine Unmöglichkeit.When turning, it is well known that the outer wheel makes more revolutions than the inner; yes this can stop completely or even turn backwards be forced. Since both wheels are connected by a rigid axle, performing these two different movements is an impossibility.

Dieser übelstand wird in dem Sportfahrzeug gemäß der Erfindung dadurch beseitigt, daß die Achse der beiden Hinterräder geteilt ausgeführt wird, so daß jede Hälfte für sich allein drehbar ist.This inconvenience is thereby in the sports vehicle according to the invention eliminates the fact that the axle of the two rear wheels is split, so that each half can be rotated on its own.

Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgedankens, und zwar in Abb. i das Fahrzeug im Gebrauch und in Abb.2qdi@e Anordnung der Hinterradachse mit den beiden Rädern.The drawing shows an embodiment of the inventive concept, namely in Fig. i the vehicle in use and in Fig.2qdi@e the arrangement of the rear wheel axle with the two wheels.

Die beiden Achsenhälften i und 2, mit je einem gegenlaufenden Gewinde versehen, sind mit ihnen äußeren Enden fest mit den Hinterrädern 3 und ,4 verbunden. Die beiden anderen Enden ruhen, jedes für sich, in Kugellabern 7 und 8, welche konzentrisch in dem gemeinsamen Gehäuse g eingesetzt sind. Auf dien 'beiden Achshälften laufen in bekannter Weise die Fußplatten 5, 6.The two halves of the axle i and 2, each with a thread running in opposite directions are provided, with them outer ends are firmly connected to the rear wheels 3 and 4. The other two ends rest, each for itself, in ball bearings 7 and 8, which are concentric are used in the common housing g. Walk on both halves of the axle the footplates 5, 6 in a known manner.

Auf diese Weise kann sich jedes der beiden Hinterräder 3 und q. unabhängig von dem anderen drehen. Das Wenden des Fahrzeuges bietet damit keine Schwierigkeiten mehr.In this way, each of the two rear wheels 3 and q. independent rotate from the other. Turning the vehicle does not present any difficulties more.
