Description
Die Erfindung bezieht sich auf eine endlose, auf die Fahrzeugräder aufzulegendie Förderraupe, insbesondere für Kinderwagen, zum Befahren vran Treppen und Unebenheiten der Fahrbahn, die aus einzelnen, gelenkig miteinander verbundenen Teilen besteht.The invention relates to an endless die to be applied to the vehicle wheels Conveyor caterpillar, especially for prams, for driving up stairs and bumps the roadway, which consists of individual, articulated parts.
Es sind bei Kinderwagen Vorrichtungen zum Befahren von Treppen und Unebenheiten der Fahrbahn bekannt, die aus einem um die Fahrzeugräder gelegten endlosen Band- bestehen, das !entweder stark gespannt oder: durch Stützrollen, unterstützt werden muß. Diese Vorrichtungen bilden bei ihrer Benutzung keine starre Gleitbahn und verur-Sachen dadurch starke Erschütterungen, wodurch sich diese Vorrichtungen für Kinderwagen nicht besonders eignen.There are known in strollers devices for climbing stairs and bumps in the road, which consist of a set to the vehicle wheels endless belt that is either very tense or: by supporting rollers, must be supported. When they are used, these devices do not form a rigid slideway and cause strong vibrations, which makes these devices not particularly suitable for strollers.
Das Neue der Erfindung besteht darin, daß die einzelnen Teile mit den einander zugewandten Flächen unmittelbar aneinanderstoßen, so daß die jeweils zwischen den Rädern liegenden Abschnitte der Förderraupe eine starre Gleitbahn bilden.The novelty of the invention is that the individual parts with each other facing surfaces abut directly, so that each between the Sections of the conveyor caterpillar lying on the wheels form a rigid slideway.
Die Fördierraupe benötigt keine Stützrollen und bedarf keiner Spannung bei der Befestigung
an den Rädern. Sie bildet bei ihrer Benutzung eine starre Gleitbahn und ermög-,
licht ein erschütterungsfreies Befahren von Treppen und Unebenheiten der Fahrbahn.
In der Zeichnung'ist die Erfindung in einem Ausführungsbeispiel dargestellt, und
zwar zeigtThe caterpillar conveyor does not require any support rollers and does not require any tension when attaching it to the wheels. When you use it, it forms a rigid slideway and enables you to drive on stairs and uneven surfaces without vibrations.
In the drawing, the invention is shown in an embodiment, namely shows

Abb. 4 die Lage der Räder gegenüber dem Wagenkasten beim Befahren von Tneppen.Fig. 4 the position of the wheels in relation to the car body when driving on steps.
Die endlose Förderraupe besteht aus einzelnen Teilen i, die durch Gelenke 2 derart miteinander verbunden sind, daß sie um die Wagenräder 3 einen Kreislauf beschreiben können und mit ihren einander zugewandten Flächen unmittelbar aneinanderstoßen, so daß die jeweils zwischen den Rädern 3 liegenden Abschnitte der Förderraupe eine starre Gleitbahn bilden.The endless conveyor caterpillar consists of individual parts i, which by joints 2 in such a way are connected to each other that they describe a cycle around the wagon wheels 3 can and directly abut each other with their facing surfaces, so that the sections of the conveyor caterpillar lying between the wheels 3 form a rigid slideway form.
Die Teile 1 sind, wie Abb. 2 zeigt, z. B. mit 5" einer Nut versehen, in der die Bereifung 4 liegt, die aus einem Vollgummiring bestehen kann.The parts 1 are, as Fig. 2 shows, for. B. with 5 " provided a groove in which the tires 4 are located, which can consist of a solid rubber ring.
Die Gelenke 2 können, wie die Abb. 1 und 2 zeigen, von einem an die Teile 1 genieteten Stahlband gebildet werden. Die Wirkung der endlosen Förderraupe ist von der Art und Gestaltung der Gelenke 2 nicht abhängig.The joints 2, like Figs. 1 and 2 show, are formed by a steel band riveted to the parts 1. The effect of the endless conveyor caterpillar does not depend on the type and design of the joints 2.
Das Fahrgestell mit der endlosen Förderraupe ist, wie die Abb. 3 und 4 zeigen, schwenkbar am Wagenkasten angeordnet, damit idie Tragfläche des Wagenkastens immer eine waagerechte Lage behält.The chassis with the endless conveyor caterpillar is, as Figs. 3 and 4 show, arranged pivotably on the car body so that the wing of the car body is always retains a horizontal position.
