Abstract

The adaptor secures a child's bicycle of up to 20 inch wheel size, to the rear of an adult bicycle with wheels of 26 or 28 inch size. The smaller bicycle can still use its own chain drive system independently of the leading bicycle, as there is no enforced synchronisation between them. The manoeuvrability of this tandem arrangement is ensured through the use of a joint between the bicycles, which permits the trailing bicycle to pitch at any angle. A height-adjustable luggage rack is used to ensure the necessary clearance between the front wheel of the smaller bicycle and the ground.

Description

Nach meinen Recherchen sind Fahrräder zur Mitnahme von Kleinkindern nur in Form von speziellen Tandems, von Fahradaufnehmern und eines sogenannten "Fahrradtrailers" bekannt. Bei den unterschiedlichsten Tandemkonstruktionen ist die Sitzposition des Kindes vor oder hinter dem Erwachsenen (z. T. mit Mitlenkmöglichkeit für das Kind). Der Fahrradtrailer bietet die Möglichkeit ein spezielles Kinderrad am Erwachsenenrad zu befestigen. Die Tandemkonstruktionen sind große, sperrige Konstruktionen, die wenn überhaupt nur schwer mit dem PKW zu befördern sind. Das Kinderrad des Fahrradtrailers ist kein selbständiges Rad und kann nicht als normales Kinderrad benutzt werden.According to my research, bicycles for taking small children are only in shape of special tandems, bike sensors and a so-called "Bicycle trailers" known. With the most diverse tandem constructions, the Sitting position of the child in front of or behind the adult (partially with possibility to steer for the child). The bike trailer offers the possibility of a special children's bike Attach adult bike. The tandem constructions are large, bulky Constructions that are difficult, if at all, to be transported by car. The Children's bike of the bike trailer is not an independent bike and cannot be considered a normal one Children's bike can be used.

Die im Schutzanspruch angegebene Erfindung ermöglicht es jedes Kinderfahrrad mit 16, 18 oder 20 Zoll Reifengröße an jedem Erwachsenenfahrrad (26 oder 28 Zoll Reifengröße) in der Art zu befestigen, daß dieses bei guter Steuerbarkeit und Wendigkeit das Umkippen des Kinderfahrrades verhindert; das bedeutet das Kinderrad wird vom Erwachsenenrad geführt und gesteuert.The invention specified in the protection claim allows any children's bike with 16, 18 or 20 inch tire sizes on each adult bike (26 or 28 inches Tire size) in the way that this with good controllability and Maneuverability prevents the children's bike from tipping over; that means the children's bike is managed and controlled by the adult bike.

Dies wird durch einen Fahrradadapter ermöglicht, dessen gelenkige Verbindung Kipp- und Drehbewegungen zuläßt aber ein seitliches Umkippen des adaptierten Kinderrades aus der Senkrechten verhindert. (Fig. 3).This is made possible by a bicycle adapter, the articulated connection of which allows tilting and rotating movements but prevents the adapted children's bike from tipping over sideways from the vertical. ( Fig. 3).

Mit dieser Erfindung wird erreicht, das jedes gängige Kinderrad mit 16,18 oder 20 Zoll Radgröße an jedem gängigen Erwachsenenrad an einem speziell verstärkten Gepäckträger befestigt werden kann. Es ist somit möglich ein noch nicht verkehrs- und fahrsicheres Kind ungefährdet durch den Straßenverkehr zu ziehen, da ein seitliches Ausbrechen oder ein unbeabsichtigter Sturz durch die stabile Führung des Erwachsenenrades ausgeschlossen ist. Dabei behält das Kinderrad seinen eigenen Kettenantrieb (keine Zwangssynchronisation wie bei Tandemkonstruktionen). Durch den einfachen Einhängemechanismus (Fig. 5) kann das Kinderrad durch wenige schnelle Handgriffe vom Erwachsenenrad gelöst und als normales Kinderrad in gewohnter Weise benutzt werden (Fig. 2). Der Adapterarm wird auf den Gepäckträger des Erwachsenenrades geklappt und dort befestigt. Er kann auch ganz vom Gepäckträger gelöst werden, so daß dieser wie ein normaler, extrem belastbarer Gepäckträger benutzt werden kann.With this invention it is achieved that any common children's bike with 16, 18 or 20 inch wheel size can be attached to any common adult bike on a specially reinforced luggage rack. It is therefore possible to safely pull a child who is not yet safe in traffic and driving through road traffic, since a sideways breakout or an unintentional fall is impossible due to the stable guidance of the adult bike. The children's bike keeps its own chain drive (no forced synchronization as with tandem constructions). Thanks to the simple attachment mechanism ( Fig. 5), the children's bike can be released from the adult bike in a few quick steps and used as a normal children's bike ( Fig. 2). The adapter arm is folded onto the luggage rack of the adult bike and fastened there. It can also be completely detached from the luggage rack so that it can be used like a normal, extremely heavy-duty luggage rack.

Ein Ausführungsbeispiel der Erfindung wird anhand der Fig. 1 bis 5 erläutert. Es zeigen:An embodiment of the invention is explained with reference to FIGS. 1 to 5. Show it:

Fig. 1 Das Kinderrad am Erwachsenenrad angekoppelt. Fig. 1 The children's bike coupled to the adult bike.

Fig. 2 Das Kinderrad vom Erwachsenenrad gelöst, der Adapterarm auf dem Gepäckträger fixiert. Fig. 2 The children's bike detached from the adult bike, the adapter arm fixed on the luggage rack.

Fig. 4 Detailzeichnung des Dreh/Kippgelenkes. Fig. 4 detailed drawing of the rotary / tilt joint.

Fig. 5 Detailzeichnung der Kinderradfixierung am Adapterarm. Fig. 5 Detail drawing of the child bike fixation on the adapter arm.

In den Figuren ist der universelle und in der Höhe verstellbare Gepäckträger mit Adapterarmaufnehmer mit 1, der Adapterarm mit 2, die Kinderradfixierung mit 3 bezeichnet.In the figures, the universal and height-adjustable luggage rack with adapter arm receiver is labeled 1 , the adapter arm 2 , the children's bike fixation 3 .

Fig. 1 zeigt das Erwachsenen- und Kinderrad im adaptierten Funktionszustand. Dabei ist eine Bodenfreiheit des Vorderrades der Kinderrades von 8-12 cm und ein Abstand zum Hinterrad des Erwachsenenrads von 15-20 cm vorhanden. Zusammen mit der in Fig. 4 dargestellten Beweglichkeit des Dreh/Kippgelenkes wird so ein gute Wendigkeit erreicht. Der mit 4 bezeichnete seitliche Anschlag verhindert das Einkippen des Kinderrades. Fig. 1 shows the adult and children's bike in the adapted functional state. There is a ground clearance of the front wheel of the children's bike of 8-12 cm and a distance from the rear wheel of the adult bike of 15-20 cm. Together with the mobility of the rotary / tilt joint shown in FIG. 4, good maneuverability is achieved. The side stop labeled 4 prevents the children's bike from tipping over.

Fig. 5 zeigt die einfache Fixation des Kinderrades am Adapterarm. Durch Anbringen der Fixierung an Steuerrohr und Vorbau des Kinderrades wird gleichzeitig mit der Ankopplung des Kinderrades der Lenker arretiert. Fig. 5 shows the simple fixation of the children's bike on the adapter arm. By attaching the fixation to the head tube and stem of the children's bike, the handlebar is locked simultaneously with the coupling of the children's bike.

Durch Bohrungen an den Gepäckträgerholmen 5 läßt sich der Gepäckträger und damit der Adapterarmaufnehmer in der Höhe verstellen, so daß eine ausreichende Bodenfreiheit des Vorderrades des Kinderrades von mindestens 10 cm auch bei unterschiedlichen Erwachsenen- und Kinderrahmengrößen gewährleistet ist.Through holes in the luggage rack spars 5 , the luggage rack and thus the adapter arm receiver can be adjusted in height, so that a sufficient ground clearance of the front wheel of the children's bike of at least 10 cm is ensured even with different adult and child frame sizes.
