Beschreibung; :Description; :

Tandem-Fahrräder sind bekannt. Auf zwei Rädern ist ein Gestell montiert mit zwei Sitzen und zwei Pedal-Treteinrichtungen. Auch Tandem-Räder mit mehreren Sitzen sind bekannt, sie kommen aber mit zunehmender Verkehrsdichte immer mehr in Bedrängnis. Dem Tandem-Fahrrad mit zwei Sitzen aber kommt eine immer mehr steigende v7ertstellung zugute, nur ist die Frage der Sicherheit eben immer mehr zu stellen. Diesem Übelstand hilft meine Erfindung ab. Dem Tandem-Fahrrad wird ein weiteres Rad beigegeben, so daß eine erheblich bessere Standfestigkeit und Straßenhaftigkeit gegeben ist. Auf drei Rädern steht das Gefährt absolut gut da, und das seitliche Umkippen, besonders auch während der Fahrt, ist nahezu ausgeschlossen. Die Gestängekonstruktion ist neuzeitlich, windschlüpfig, sportlich-elegant, mit zwei Leuchten ausgestattet, die batteriegetrieben sind Fig. 1/c/d - Fig.2/c/d.Tandem bicycles are well known. A frame with two seats and two pedals is mounted on two wheels. Tandem bicycles with several seats are also well known, but they are becoming increasingly problematic as traffic density increases. The tandem bicycle with two seats is, however, increasingly gaining ground, but the question of safety is becoming more and more important. My invention solves this problem. The tandem bicycle is given an additional wheel, which means it is much more stable and roadworthy. The vehicle stands absolutely well on three wheels, and tipping over sideways, especially while driving, is almost impossible. The rod construction is modern, aerodynamic, sporty and elegant, and is equipped with two lights that are battery-operated Fig. 1/c/d - Fig.2/c/d.

Fig.l stellt das Tandem-Fahrrad in der Läagssicht dar, Fig.2 zeigt die Draufsicht. Hehr Raum beim Abstellen wird nicht benötigt, es äst auch da mehr Sicherheit gegeben. Die beim Fahren eingesetzte Tretkraft beider Fahrer kann bei diesem Fahrzeug besser umgesetzt werden, da eine statisch gesteigerte Umsetzung erfolgt.Fig. 1 shows the tandem bike in a longitudinal view, Fig. 2 shows the top view. A lot of space is not needed when parking, and there is also more safety. The pedal power used by both riders when riding can be better implemented with this vehicle, as there is a statically increased implementation.

Ss ist nicht nötig, das Fahrzeug beim Abstellen an irgend einen Gegenstand anzustellen, es kann so stehen bleiben, wie es verlassen wird.It is not necessary to park the vehicle against any object; it can remain as it was when you left it.
