Abstract

The learning bicycle has a simple frame with no upper crossbar and with a foot support platform (2) on the lower frame. This enables the machine to be used as a scooter. When the user has obtained confidence and balance, the transmission can be clipped into place and the machine used as a bicycle. The crankwheel, pedals, chain and chain guard are fitted as one unit to prepared mountings. The saddle and handlebars are height adjustable between bicycle- and scooter use. ADVANTAGE - Dual purpose machine, simple learning system.

Description

Die Erfindung betrifft ein Laufrad mit einem Rahmen und zwei auf ge­ trennten Achsen angeordneten Rädern an den Enden des Rahmens, wobei das am vorderen Ende des Rahmens angeordnete Rad lenkbar ist. Laufräder, der oben beschriebenen Art können von Kindern benutzt wer­ den, um das Halten des Gleichgewichtes zu erlernen.The invention relates to an impeller with a frame and two on ge separate axles arranged wheels at the ends of the frame, being the wheel located at the front end of the frame is steerable. Impellers of the type described above can be used by children to learn to keep balance.

Wenn die Kinder das Gefühl für das Gleichgewicht auf einem Zweirad erlernt haben und auf ein Fahrrad mit Kettenantrieb umsteigen möchten, besteht häufig die Schwierigkeit, ein Fahrrad zu finden, das der Körpergröße des Kindes angepaßt ist. In vielen Fällen sind die Ab­ stände vom Sattel zum Tretlager und vom Sattel zur Lenkstange nicht auf das kindgerechte Körpermaß in den einzelnen Altersstufen ausge­ richtet.When the children feel for balance on a two-wheeler have learned and want to switch to a bicycle with chain drive, there is often a difficulty in finding a bike that the Height of the child is adjusted. In many cases, the Ab from the saddle to the bottom bracket and from the saddle to the handlebar based on the child-appropriate body size in the individual age groups judges.

Obwohl das Kind in der Lage ist, hat es aufgrund eines fehlenden Fahr­ rades mit der für ein Kind sinnvollen Größe erhebliche Schwierigkei­ ten, das Fahrradfahren zu erlernen.Although the child is able, it has due to a lack of driving rades with the size meaningful for a child considerable difficulty to learn to ride a bike.

Es ist daher die der Erfindung zugrundeliegende Aufgabe, ein Laufrad zu schaffen, das dem Kind das Erlernen des Fahrradfahrens erheblich erleichtert und die Körpergröße des Kindes berücksichtigt.It is therefore the object underlying the invention, an impeller to create a learning cycle for the child significantly relieved and taking into account the child's height.

Die wird gemäß der Erfindung erreicht durch einen aus Ritzes, Ketten­ rad mit Tretkurbeln und Kette bestehenden Anbausatz, dessen Ritzel an der Hinterachse des Laufrades befestigbar ist und dessen Ketten­ rad in einem Lager abstützbar ist, das an einem zum Sattel aufstei­ genden Rahmenteil des Fahrrades versetzbar befestigt ist.This is achieved according to the invention by one of Ritzes, chains wheel with pedal cranks and chain existing mounting kit, the pinion is attachable to the rear axle of the wheel and its chains Rad can be supported in a camp that ascends to a saddle the frame part of the bicycle is attached displaceably.

Der Anbausatz macht es in einfacher Weise möglich, das Laufrad zu einem Fahrrad mit Tretantrieb umzugestalten, wobei aufgrund der Ver­ setzbarkeit des Lagers für das Kettenrad die körpergerechte Anpassung des zum Fahrrad umgestalteten Laufrades gewährleistet ist. Mit dem erfindungsgemäßen Laufrad ist es deshalb möglich, daß ein Kind jegli­ cher Altersstufe auf einfache Weise das Fahrradfahren erlernen kann.The mounting kit makes it easy to close the impeller remodel a bicycle with pedal drive, due to the Ver adjustability of the bearing for the sprocket the body-appropriate adjustment of the wheel that has been transformed into a bicycle is guaranteed. With the Impeller according to the invention it is therefore possible that a child each age can easily learn to ride a bike.

Ein Ausführungsbeispiel der Erfindung wird anhand von Zeichnungen näher erläutert. In den Zeichnungen zeigen:An embodiment of the invention will become apparent from the drawings explained. The drawings show:

Fig. 1 Eine Seitenansicht eines Laufrades Fig. 1 is a side view of an impeller

Fig. 2 Eine Seitenansicht eines erfindungsgemäßen Anbausatzes Fig. 2 is a side view of a kit according to the invention

Fig. 3 Eine Seitenansicht des erfindungsgemäßen Laufrades mit angebautem Anbausatz. Fig. 3 is a side view of the impeller according to the invention with attached mounting kit.

Fig. 1 zeigt ein Laufrad 1 mit einem Rahmen 2, einem Hinterrad 3 und einem in einer Lenkergabel 4 gelagerten Vorderrad 5. Der Rahmen 2 weist einen in der Höhe verstellbaren Sattel 6 auf; der zum Sattel 6 aufsteigende Rahmenteil 7 enthält einen verstellbarbefestigten Lageransatz 8 Fig. 1 shows a wheel 1 with a frame 2, a rear wheel 3 and a handlebar mounted in a fork 4. front wheel 5. The frame 2 has a height-adjustable saddle 6 ; the frame part 7 rising to the saddle 6 contains an adjustably fixed bearing attachment 8

Fig. 2 zeigt einen Anbausatz 10 mit einem Ritzel 11, einem Ketten­ rad 12 mit Tretkurbeln 13 und einer endlosen Kette 14. Der Anbausatz 10 kann mit einem umlaufenden Kettenschutz verse­ hen sein. Das Ritzel 11 des Anbausatzes 10 ist auf die Achse des Hinterrades 3 ansteck- und befestigbar, während die Achse des Kettenrades 12 in den Lageransatz 8 einsetzbar ist, der auf die Achse des Hinterrades und in den Lageransatz 8 auf­ gesteckte Anbausatz 10 ist gegen ein Lösen vom Rahmen gesi­ chert. Fig. 2 shows a mounting kit 10 with a pinion 11 , a chain wheel 12 with cranks 13 and an endless chain 14th The attachment kit 10 can be hen with a circumferential chain guard. The pinion 11 of the attachment extension 10 is clip-to the axis of the rear wheel 3 and fastened, while the axis of the sprocket 12 is inserted into the bearing boss 8 which is on the axis of the rear wheel and in the bearing lug 8 inserted mounting set 10 against loosening secured by the frame.

Fig. 3 Ist das Laufrad mit aufgestecktem Anbausatz dargestellt, wobei gleiche Bezugszeichen gleiche Teile bezeichnen. Fig. 3 The impeller is shown with attached mounting kit, the same reference numerals designating the same parts.
