Abstract

The vehicle has an inflatable float (2) which can be attached to a bicycle (1) or other cycle, so that little rearrangement is required to alter it from land use to water use or vice versa. A pump may be included, coupled to the bicycle drive so that the float can be more readily and rapidly inflated by the cyclist's own muscle power.

Description

Die Erfindung besteht darin, ein handelsübliches Fahrrad (1) mit je einem Schwimmkörper (2) links und rechts auszustatten, um amphibische Eigenschaften zu erreichen.The invention consists in equipping a commercially available bicycle ( 1 ) with a floating body ( 2 ) on the left and right in order to achieve amphibious properties.

Die beiden aufblasbaren Schwimmkörper sind an einem Gelenk (3) jeweils um 90 Grad umklappbar am Fahrradrahmen angeschraubt. Nach oben geklappt und entlüftet sind die Schwimmkörper nicht größer als zwei Packtaschen, das Fahrrad lässt sich an Land normal bewegen.The two inflatable floats are screwed to the bicycle frame at a joint ( 3 ) which can be folded down by 90 degrees. Folded up and vented, the floats are no larger than two panniers, the bike can be moved normally on land.

Zum Wasserbetrieb werden die beiden Schwimmkörper umgeklappt und können mit einer, in den Fahrradantrieb mittels eines Kurbeltriebes integrierten, doppelhübigen Kolbenpumpe in wenigen Minuten aufgeblasen werden. Das Rad kann zu diesem Zweck auf einem speziellen Ständer aufgebockt werden.For water operation, the two floats are folded down and can be used one, double-stroke integrated in the bicycle drive by means of a crank drive Piston pump can be inflated in a few minutes. The wheel can go to this Purpose to be jacked up on a special stand.

Mit aufgeblasenen und abgeklappten Schwimmkörpern besitzt das Rad noch genug Bodenfreiheit um ins Wasser geschoben zu werden.With inflated and folded floating bodies, the bike still has enough Ground clearance to be pushed into the water.

Der Vortrieb im Wasser erfolgt durch eine Schiffsschraube oder durch Schaufeln, die in den Speichen des Hinterrades befestigt sind.The propulsion in the water is carried out by a propeller or by shovels, which are fixed in the spokes of the rear wheel.

Das Vorderrad besitzt eine Verkleidung, so daß es als Ruder wirkt. (siehe Hierzu 1 Seite Zeichnung)The front wheel has a fairing so that it acts as a rudder. (see 1 page drawing)

Wirtschaftliche NutzungEconomic use

Das oben beschriebene Fahrzeug wird in erster Linie im Verleih als Freizeitgerät Einsatz finden.The vehicle described above is primarily for rental as a recreational device Find use.

Der Amphibiencharakter ermöglicht die Vermietung eines Wasserfahrzeugs ohne daß dazu teure Wasserliegeplätze benötigt werden.The amphibious character enables the rental of a watercraft without that expensive water berths are needed.

Stand der TechnikState of the art

Es existiert bereits ein Amphibisches, pedalgetriebenes Land- und Wasserfahrzeug (Pat. Nr. DE 44 10 813 A1). Dies ist jedoch aufgrund seiner selbsttragenden und als Bootskörper ausgebildeten Karosserie aufwendiger und damit wesentlich teurer als die hier vorgestellte Erfindung.An amphibious, pedal-powered land and water vehicle already exists (Pat. No. DE 44 10 813 A1). However, this is due to its self-supporting and as Boat hull-trained bodywork is more complex and therefore much more expensive than the invention presented here.

Claims (2)

Amphibisches, pedalgetriebenes Land- und Wasserfahrzeug, gekennzeichnet durch die Anbringung aufblasbarer Schwimmkörper an einem Fahrrad (auch Tandem, Liegerad) in der Weise, daß durch minimale Umrüstung der Betrieb zu Land und zu Wasser möglich ist.1. Amphibious, pedal-driven land and water vehicle, characterized by the attachment of inflatable floats on a bicycle (also tandem, recumbent) in such a way that operation on land and water is possible with minimal retrofitting. 2. Amphibisches, pedalgetriebenes Land- und Wasserfahrzeug, gekennzeichnet durch die Möglichkeit, die Schwimmkörper schnell durch eine an den Fahrradantrieb gekoppelte Pumpe aufzublasen.2. Amphibious, pedal-driven land and water vehicle, characterized by the ability to quickly attach the float to the bicycle drive inflate the coupled pump.
