Abstract
Teilbares
dreirädriges
Tandemfahrzeug, das durch folgende Merkmale gekennzeichnet ist:
– Es besteht
aus 2 handelsüblichen
Fahrrädern,
deren Rahmen, (A, B), nur geringfügig abgeändert sind.
– Am vorderen
Fahrrad-Rahmen, (A), ist hinter dem Sattel ein Gelenk, (1), mit
zwei Freiheitsgraden angebracht. Zwei Freiheitsgrade bedeutet: von
sechs Bewegungen, die überhaupt
zwischen (A) und (B) theoretisch auftreten können, ermöglicht das Gelenk, (1), zwei.
– Am hinteren
Fahrrad-Rahmen, (B), ist vor dem Lenkkopfrohr, (5), ein Kragarm,
(2), angebracht, der schnell ans Gelenk, (1), an- oder abgekoppelt
werden kann.
– Der
Kragarm, (2), behindert die Einzelfahrrad-Funktion nicht.
– Am hinteren
Fahrrad-Rahmen, (B), kann mit wenig Aufwand, das heisst während einer
Fahrradtour, unterwegs eine mitgeführte Fahrradgabel, (3a), an-
oder abmontiert werden.Divisible three-wheeled tandem vehicle, characterized by the following features:
- It consists of 2 standard bicycles whose frame, (A, B), are only slightly modified.
- On the front bicycle frame, (A), behind the saddle is a joint, (1), with two degrees of freedom. Two degrees of freedom means: of six movements that can theoretically occur between (A) and (B), the joint, (1), allows two.
- At the rear bicycle frame, (B), in front of the steering head tube, (5), a cantilever arm, (2), attached, which can be quickly coupled to the joint, (1), or disconnected.
- The cantilever arm, (2), does not hinder the single-bike function.
- At the rear bicycle frame, (B), with little effort, that is, during a bike ride, on the road a bike fork, (3a), attached or removed.
Description
Dieses Fahrrad, im folgenden Fahrzeug genannt, besteht aus zwei, auch für sich allein funktionierenden Einzelfahrrädern für Erwachsene, die bei Bedarf zusammengekoppelt werden können. Diese entsprechen – abgesehen von leichten Umbaumassnahmen – der Form und der Ausstattung heute üblicher Fahrräder. Im Tandembetrieb kann jede Person unabhängig pedalieren und ihre Trittfrequenz mittels der herkömmlichen Fahrradgangschaltungen variieren.This Bicycle, called in the following vehicle, consists of two, also alone functioning single bicycles for adults, which can be coupled together as needed. These correspond - apart of light reconstruction measures - the Form and equipment more common today Cycles. In tandem operation, each person can independently pedal and their cadence by means of the conventional Bicycle gears vary.
