Abstract

The invention relates to the possibility of setting the horizontal distance of the handgrips from the seat in the case of vehicles which can be operated by muscular power. The hitherto known possibilities of setting via the add-on pieces lead to secondary effects: if the saddle is displaced horizontally, the inclination of the connecting line between bottom bracket ball bearing and saddle, which is of fundamental importance for the ergonomics of the tread crank drive, also changes. If the position of the handlebar is altered, the controlling properties also change with it. In order to avoid these influences to a large extent and to increase the possibilities of variation of the longitudinal adaptation, above all in the case of bicycles for children and youths and special vehicles such as wheelchair-bicycles ("wheelchair-rickshaws"), it is proposed to design the bicycle frame such that its length is variable. This can be achieved by the steering head being connected to the rear structure of the vehicle by means of a telescope-like tube connection. In the case of a suitable design, the mechanism of the longitudinal adjustment can also be used for separating the vehicle into more easily storable parts.

Description

Bei durch Muskelkraft betreibbaren Fahrzeugen spielt die Körperhaltung des Fahrers eine wesentliche Rolle. Die hori­ zontale Distanz der Handgriffe zum Sitz kann nach heutigem Stand der Technik durch entsprechende Position relevanter Anbauteile eingestellt werden. So ist die Position des Sattels gegenüber der Sattelstütze horizontal variabel und durch Verdrehen und/oder Verschieben des Lenkerbügels läßt sich die Position der Handgriffe gegenüber dem Lenkervor­ bau einstellen. Diese Einstellmöglichkeiten haben jedoch Nebeneffekte: Die Veränderung der Sattelposition beein­ flußt zwangsläufig die für die Kraftentfaltung beim Treten wesentliche Neigung der Linie Tretlagerachse - Sattel. Die Veränderung der Lenkergriffposition verändert zwangs­ läufig die Stellung der Hände gegenüber der Lenkachse und damit die Steuereigenschaften.In vehicles that can be operated by muscle power, the Posture of the driver plays an essential role. The hori Zontal distance of the handles to the seat can today State of the art more relevant by corresponding position Attachments can be adjusted. So is the position of the Saddles horizontally variable and opposite the seat post by turning and / or moving the handlebar the position of the handles in relation to the handlebar stop building. However, these setting options have Side effects: The change in the saddle position affects flows inevitably for the power development at Significant incline of the bottom bracket axis - saddle line. The change in the handlebar position changes forcibly the position of the hands in relation to the steering axis and hence the control properties.

Der Erfindung liegt die Aufgabe zugrunde, eine Längen­ anpassung für Muskelkraft - betreibbare Fahrzeuge so zu gestalten, daß diese Nebeneffekte weitgehend oder ganz vermieden werden. Darüber hinaus soll die Erfindung ge­ eignet sein, eine Längenanpassung bei Fahrzeugen zu er­ möglichen, deren Aufbau die oben beschriebenen Anpassungs­ möglichkeiten nicht oder nur unvollkommen gestattet, wie beispielsweise bei Kombinationsfahrzeugen aus Rollstuhl und Fahrrad. The invention has for its object a length adjustment for muscle strength - so operable vehicles shape that these side effects largely or entirely be avoided. In addition, the invention is intended to be ge be suitable to adjust the length of vehicles possible, the structure of which is described above possibilities not or only incompletely permitted, such as for example in combination vehicles from wheelchairs and bike.  

Desweiteren soll die Möglichkeit geschaffen werden, durch Muskelkraft betreibbare Fahrzeuge so zu gestalten, daß sie für sehr unterschiedliche Körpergrößen und Körperverhält­ nisse angepaßt werden können. Dies ist insbesondere wesentlich bei Fahrzeugen für Kinder und Behinderte.Furthermore, the possibility is to be created through Muscle power operated vehicles so that they for very different body sizes and body proportions nisse can be adjusted. This is particularly important for vehicles for children and the disabled.

Erfindungsgemäß wird vorgeschlagen, diese Aufgaben dadurch zu lösen, daß der Rahmenaufbau längenveränderlich gestaltet wird. Dies kann ohne großen Bauaufwand realisiert werden, indem eine teleskopartig verschiebbare Rohrverbindung vom Lenkkopf zum Sattelrohr des Hinterbaues führt. Verrutschen der eingestellten Rahmenlänge kann durch Klemmverschraubung verhindert werden. Sicherheit, insbesondere gegen Verdrehen, kann zusätzlich ein radial angeordneter, federnd einrasten­ der Bolzen oder eine entsprechend angeordnete, zusätzliche Verschraubung gewährleisten. Bei geeigneter Bauweise kann die Mechanik der Längenverstellung auch zur Trennung des Fahrzeuges in leicht verstaubare Teile genutzt werden. According to the invention, it is proposed to perform these tasks to solve that the frame structure is variable in length becomes. This can be done without much construction effort, by a telescopically displaceable pipe connection from Steering head leads to the seat tube of the rear triangle. Slipping the set frame length can be adjusted by means of compression fittings be prevented. Security, especially against twisting, can also snap in a radially arranged, resilient the bolt or a correspondingly arranged, additional Ensure screw connection. With a suitable construction can the mechanics of the length adjustment also to separate the Vehicle can be used in easily stowable parts.
