Abstract

Das Innovative an dieser Faltung ist, dass das Hinterrad durch die Streben des zweigeteilten Ober- und Unterrohrs eintaucht.
Die Länge des Fahrrads verringert sich bei dieser Form der Faltung auf rund 60% während die Breite konstant bleibt.
Anwendungsgebiet
Als Fahrzeug fürs öffentliche Straßenland
Vorteile:
Falträder weisen häufig sehr kleine Räder auf, um ein kleines Packmaß zu erreichen. Damit gehen aber auch Nachteile einher. Die vorliegende Falttechnik erlaubt ein kompaktes Faltmaß auch mit normal großen Reifen, z. B. 28-Zoll-Reifen.The innovative thing about this folding is that the rear wheel dips through the struts of the split upper and lower tube.
The length of the bicycle decreases in this form of folding to about 60% while the width remains constant.
field of use
As a vehicle for public roads
Advantages:
Folding bikes often have very small wheels to achieve a small pack size. But there are also disadvantages. The present folding technique allows a compact folding size even with normal sized tires, z. B. 28 inch tires.

Description

Die Erfindung betrifft ein Fahrrad-Faltsystem.The invention relates to a bicycle folding system.

Es gibt nur wenige innovative Faltsysteme für Falträder, fast alle sind seitlich gefaltet.There are only a few innovative folding systems for folding bikes, almost all are folded laterally.

Die zum Gebrauchsmuster angemeldete Erfindung ist eine innovative Sonderform eines faltbaren Fahrrades. Falträder mit seitlicher Faltung gibt es seit 1896. Die zum Patent eingereichte Erfindung ist das nach »innen« faltende Fahrrad, wobei das hintere Laufrad zwischen den zwei parallelen Rahmenstreben des Oberrohr 2 (1) und des Unterrohrs 4 (1) eintaucht.The invention registered in the utility model is an innovative special form of a foldable bicycle. Folding bikes with side folding have been around since 1896. The invention filed for patent is the "folding in" bicycle, with the rear wheel between the two parallel frame struts of the top tube 2 ( 1 ) and the down tube 4 ( 1 immersed).

Gängige Falträder sind in der Regel mit kleinen Laufrädern ausgestattet, was sich negativ auf Geschwindigkeit, Laufruhe und Fahrspaß auswirkt. Dies betrifft insbesondere Mountainbiker und Rennradfahrer.Common folding bikes are usually equipped with small wheels, which has a negative impact on speed, smoothness and driving pleasure. This applies especially to mountain bikers and road cyclists.

Aufgabe der Erfindung ist es, ein Faltrad anzugeben, dass große Laufräder ermöglicht. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet.The object of the invention is to provide a folding bike that allows large wheels. This object is solved by the features of claim 1. Advantageous embodiments are characterized in the subclaims.

Die Druckschrift WO 2015/121 289 A1 zeigt ein Faltrad, dessen Hinterrad zwar nach vorne innen gefaltet wird, aber trotzdem nur für kleine Laufräder ausgelegt ist.The publication WO 2015/121 289 A1 shows a folding bike, the rear wheel is indeed folded forward inside, but is still designed only for small wheels.

Die Zeichnungen 1–4 zeigen den faltbaren Fahrradrahmen.The painting 1 - 4 show the foldable bicycle frame.

Drei Scharniere 1a, 1b und 3 (1), davon die ersten beiden mit einer Arretierung, sowie die beiden Kugellager 6 (1) erlauben es, die Hinterradgabel 7 mit den Ausfallenden 5 nach vorne Richtung Steuerrohr 8 zu falten.Three hinges 1a . 1b and 3 ( 1 ), of which the first two with a lock, as well as the two ball bearings 6 ( 1 ) allow the rear fork 7 with the dropouts 5 forward towards the head tube 8th to fold.

Im ausgefalteten Zustand sorgt die Arretierung der Scharniere 1a und 1b für die Sicherheit und Steifigkeit beim Radfahren.In the unfolded state ensures the locking of the hinges 1a and 1b for safety and rigidity when cycling.
