    Kinderfahrrad   aus Holz mit Trethebelantrieb. 



   Der Gegenstand der Erfindung betrifft ein Kinderfahrrad aus Holz mit Trethebelantrieb und besteht in der leichten Holzkonstruktion des Rahmengestelles, u. zw. derart, dass die am meisten beanspruchten Rahmenstangen nicht durchgehend aus einem widerstandsfähigen Hartholz, wie Eschenholz u. dgl., hergestellt sind, wodurch das Kinderfahrrad zu schwer werden würde, sondern dass diese Rahmenstangen aus zwei einen Weichholzkern umfassenden Eschenleisten verfertigt sind. 



   Der Erfindungsgegenstand ist in der Zeichnung veranschaulicht, u. zw. zeigt Fig. 1 eine Seitenansicht, Fig. 2 eine Draufsicht des Kinderfahrrades. Fig. 3,4 und 5 stellen Einzelheiten dar. 



   Das Kinderfahrrad ist zur Gänze bis auf die Verbindungsbolzen, die Kurbel und Radachsen aus Holz hergestellt. Um ein möglichst leichtes Gewicht des Kinderfahrrades zu erzielen, bestehen die Haupt-

 leisten (siehe Fig. 5). Zum Antrieb des Fahrrades sind zwei Trethebel 5 und 6 vorgesehen, die mit der Kurbel des Hinterrades durch Lenker 14 verbunden sind. Am vorderen Ende der Trethebel sind Pedale der Fusssohlenbewegung entsprechend schwingbar angeordnet. Das Pedal besitzt zu diesem Zwecke zwei Augen 7, welche mittels Bolzen auf einem Wiegenlager 8 befestigt sind. Zur Einstellbarkeit der Entfernung des Pedals vom Sattel ist das Pedal im Trethebel verschiebbar gelagert. Die Achse des Hinterrades ist zweiteilig ausgeführt (s. Fig. 3) und durch Überplattungen sind diese beiden Teile 9, 10 miteinander verbunden. Über die Hinterradachse wird eine Hülse 11 geschoben.

   Die Hinterradachse ist mittels zweier Prisonstifte 12, 13 mit der Radnabe fix verbunden.

    Children's bicycle made of wood with pedal drive.



   The object of the invention relates to a children's bicycle made of wood with a pedal drive and consists in the light wooden structure of the frame, u. zw. Such that the most stressed frame bars are not consistently made of a resistant hardwood such as ash wood and the like. Like. Are made, whereby the children's bike would be too heavy, but that these frame bars are made of two ash strips comprising a soft wood core.



   The subject of the invention is illustrated in the drawing, u. Between Fig. 1 shows a side view, Fig. 2 shows a plan view of the children's bicycle. Figures 3, 4 and 5 show details.



   The children's bike is made entirely of wood, except for the connecting bolts, the crank and the wheel axles. In order to achieve the lightest possible weight of the children's bike, the main

 make (see Fig. 5). To drive the bicycle, two pedal levers 5 and 6 are provided, which are connected to the crank of the rear wheel by handlebars 14. At the front end of the pedal levers, pedals are arranged to swing in accordance with the movement of the sole of the foot. For this purpose the pedal has two eyes 7 which are fastened to a cradle bearing 8 by means of bolts. To adjust the distance of the pedal from the saddle, the pedal is slidably mounted in the pedal lever. The axle of the rear wheel is made in two parts (see Fig. 3) and these two parts 9, 10 are connected to one another by overlapping. A sleeve 11 is pushed over the rear wheel axle.

   The rear wheel axle is fixedly connected to the wheel hub by means of two prison pins 12, 13.
