Abstract

The invention relates to a bicycle provided with an electric motor (1) which can be optionally connected to the rear bicycle wheel (11) or to other positions. The power supply device, namely powerpacks/batteries (5), are arranged at the center of gravity of the bicycle, namely in the supporting lower tube (4) of the bicycle frame such that a lowest possible center of gravity results. The lower tube can be equipped with batteries by bending the rear wheel which is mounted in a hinged manner (8). The power supply device cannot be observed by third parties since the appearance of the bicycle is not altered by the powerpack.

Description

Fahrrad mit: Einrichtung zur Energieversorgung eines Elektromotors Bicycle with: Device for the energy supply of an electric motor
Beschreibungdescription
Die Erfindung betrifft ein Fahrrad, im wesentlichen bestehend aus einem aus Oberrohr und aus tragendem Unterrohr gebildeten Fahrradrahmen, einem mit dem Unterrohr verbundenen Tretlager, einem mit dem Unterrohr verbunde- nen Hinterradausleger und mit einem durch in dem Far- radrahmen angeordneten Batterien angetriebenen Elektromotor.The invention relates to a bicycle, consisting essentially of a bicycle frame formed from the upper tube and a supporting down tube, a bottom bracket connected to the down tube, a rear wheel boom connected to the down tube and an electric motor driven by batteries arranged in the far frame.
Seit einiger Zeit sind Fahrräder bekannt, die sich dadurch auszeichnen, daß sie neben dem normalen Antrieb über das Tretlager und dem damit verbundenen mechanischen Kettenantrieb auch noch über einen Elektromotor verfügen. Dieser Elektromotor greift im allgemeinen ebenfalls am Hinterrad des Fahrrades an. Daneben sind natürlich sogenannte Mofas bekannt, die ihren Motor (Elektro- oder Ben- zinmotor) teilweise auch am Vorderrad haben.Bicycles have been known for some time, which are characterized in that they have an electric motor in addition to the normal drive via the bottom bracket and the associated mechanical chain drive. This electric motor generally also acts on the rear wheel of the bicycle. In addition, so-called mopeds are of course known, some of which have their engine (electric or petrol engine) on the front wheel.
Derartige halbmechanische Fahrräder sind üblicherweise in Diamant-Bauweise aufgebaut und dienen dazu, die Beförderung zum einen schneller und komfortabler zu machen und zum anderen den Fahrradfahrer zu entlasten. Die Zielgrup- pe der halbmechanischen bzw. motorisierten Fahrräder sind Stadtkuriere (Fahrradkuriere) aber auch „normale" Personen, die sich nicht auf dem Fahrrad verausgaben können oder wollen. Ein herkömmlicher Diamantrahmen besteht aus einem unteren und einem oberen Rohr, sowie einer Sitz- strebe und Kettenstrebe die über das Sattelrohr in einer einem Diamanten angenäherten geometrischen Struktur miteinander verbunden sind; das Tretlager ist im Schnittpunkt von unterem Rohr, Sattelrohr und Kettenstrebe ange- ordnet.Such semi-mechanical bicycles are usually constructed in diamond construction and serve to make transportation quicker and more comfortable on the one hand and to relieve the cyclist on the other. The target group of semi-mechanical or motorized bicycles are city couriers (bicycle couriers) but also "normal" people who cannot or do not want to spend themselves on bicycles. A conventional diamond frame consists of a lower and an upper tube, as well as a seat stay and chain stay which are connected to each other via the seat tube in a geometric structure approximating a diamond; the bottom bracket is located at the intersection of the lower tube, seat tube and chain stay.
Derartige bekannte Fahrräder haben den Nachteil, daß die Energieversorgungseinrichtung für den Elektromotor, der üblicherweise dem Fahrrad zuschaltbar ist und nicht permanent angeschlossen ist, an Positionen des Fahrrades an- geordnet sind, die ungeeignet sind, da sie zum einen den verfügbaren, äußeren Platz am Fahrradrahmen (z.B. Satteltasche, Gepäckträger, Rahmengestell) unnötig ausfüllen und zum anderen auch gewichtsmäßig belasten, so daß das Fahrrad gegebenenfalls leicht aus dem Gleichgewicht ge- rät, da die Energieversorgungseinrichtungen sehr hoch über dem Boden angebracht sind und den Schwerpunkt des Fahrrades somit erhöhen. Als Energieversorgungseinrichtung dienen üblicherweise Batterien bzw. Akkus auf Nikkei/Cadmiu - Basis, die über ein hohes spezifisches Ge- wicht verfügen. Nachteilig an einer äußeren Anbringung der Batterien ist zudem, daß diese leicht durch Dritte entwendet werden können.Known bicycles of this type have the disadvantage that the energy supply device for the electric motor, which can usually be connected to the bicycle and is not permanently connected, is arranged in positions of the bicycle which are unsuitable because, on the one hand, they have the available external space on the bicycle frame (eg saddlebag, luggage rack, frame) fill out unnecessarily and, on the other hand, load the weight, so that the bike can easily get out of balance, since the energy supply devices are very high above the ground and thus increase the center of gravity of the bike. Batteries or rechargeable batteries based on Nikkei / Cadmiu, which have a high specific weight, are usually used as the energy supply device. Another disadvantage of an external attachment of the batteries is that they can easily be stolen by third parties.
Aus dem Stand der Technik ist noch die DE 30 18 333 AI bekannt, die ein Fahrrad mit einem im wesentlichen übli- chen Fahrradrahmen und einem darin integrierten Elektromotor und Akkumulatoren zeigt. Nicht beschrieben ist, wie die Akkumulatoren in den Rahmen einbringbar sind. Auch ist das Gewicht eines derartigen Fahrrades sehr hoch und das gesamte Fahrrad ist nicht austariert. Der Motor wird erst bei einer bestimmten Drehzahlfrequenz aktiviert. Die DE 42 19 579 C2 beschreibt ein Fahrrad mit einem offenen Unterrohr, jedoch ohne Motor und ohne Energiemittel. Letztlich beschreibt die EP 0 268 338 A2 ein Fahrrad mit Lichtsystem, jedoch ohne Motor, wobei die Akkumulato- ren nicht aus dem Rahmen entfernbar sind, sondern von außen aufgeladen werden müssen.DE 30 18 333 A1 is also known from the prior art, which shows a bicycle with an essentially conventional bicycle frame and an electric motor and accumulators integrated therein. It is not described how the batteries can be inserted into the frame. The weight of such a bicycle is also very high and the entire bicycle is not balanced. The motor is only activated at a certain speed frequency. DE 42 19 579 C2 describes a bicycle with an open down tube, but without a motor and without energy. Ultimately, EP 0 268 338 A2 describes a bicycle with a light system, but without a motor, the batteries not being removable from the frame, but having to be charged from the outside.
Aufgabe der vorliegenden Erfindung ist es daher, die Energieversorgungseinrichtung derart am Fahrrad zu plazieren, daß der Schwerpunkt nicht zu hoch gerät und der zur Verfügung stehende „Stauraum" des Fahrrades nicht mit der Energieversorgungseinrichtung belastet wird.The object of the present invention is therefore to place the energy supply device on the bicycle in such a way that the center of gravity does not become too high and the available "storage space" of the bicycle is not burdened with the energy supply device.
Gelöst wird diese Aufgabe dadurch, daßThis task is solved by the fact that
- der Elektromotor außerhalb des aus Oberrohr, Unterrohr, Sattelrohr und Tretlager gebildeten Fahradrahmens angeordnet ist- The electric motor is arranged outside the bicycle frame formed from the top tube, down tube, seat tube and bottom bracket
und durch Batterien gespeist wird, die nah am Schwerpunkt des Fahrrades innerhalb des Unterrohres angeordnet sind,and is powered by batteries located close to the center of gravity of the bike within the down tube,
- wobei die Batterien von unten in das Unterrohr ein- führbar sind.- The batteries can be inserted into the down tube from below.
Durch diese erfindungsgemäße Maßnahme wird erreicht, daß die Energieversorgungseinrichtung nicht sichtbar am Fahrrad angeordnet ist. Der Vorteil besteht also unter anderem darin, daß die Energieversorgungseinrichtung durch Dritte auch nicht entwendet werden kann. Ein weiterer Vorteil besteht darin, daß die Energieversorgungseinrichtung im tragenden Unterrohr angeordnet ist, wodurch die Gewichtsverteilung einen möglichst -tiefen Schwerpunkt ergibt. Dies erhöht eine bessere Straßenlage und auch Sicherheit des Fahrrades. Weiterer Vorteil der Erfindung ist es, daß das gesamte Unterrohr mit Batterien als Ener- gieversorgungseinheiten versorgt werden kann. Hierzu werden üblicherweise nicht einzelne Batterien verwendet, sondern Batteriepacks/-kartuschen, die in Serie geschaltet (wie bei einer normalen Stabtaschenlampe) in das Unterrohr eingeschoben werden können. Erfindungsgemäß sind hierzu innerhalb des Unterrohres Kontakte angeordnet, die für einen Stromfluß sorgen. Die Zugangsmöglichkeit zum Unterrohr ist durch einen Verschluß gegeben, der an dem unteren Ende des Unterrohres angeordnet ist. Durch einfaches mechanisches Abschrauben bzw. Entriegeln des Ver- Schlusses lassen sich von unten einzelne oder mehrere Batteriepacks in das Unterrohr einschieben. Falls das Unterrohr nicht vollständig mit Batteriepacks ausgefüllt werden kann oder soll, ist hierzu vorgesehen, daß im Innern des Unterrohres ein federnder Kontakt vorgesehen ist, der zum einen für einen permanenten Kontakt mit den Batterien sorgt, zum anderen aber auch die Batterien federnd hält.This measure according to the invention ensures that the energy supply device is not arranged visibly on the bicycle. One of the advantages is that the energy supply device cannot be stolen by third parties. Another advantage is that the energy supply device is arranged in the supporting down tube, whereby the Weight distribution gives the lowest possible center of gravity. This increases better road holding and also safety of the bike. A further advantage of the invention is that the entire down tube can be supplied with batteries as energy supply units. Usually not individual batteries are used for this, but battery packs / cartridges that can be inserted in series (like a normal rod torch) and inserted into the down tube. According to the invention, contacts are arranged for this purpose within the down tube, which ensure a current flow. Access to the down tube is given by a closure which is arranged at the lower end of the down tube. By simply mechanically unscrewing or unlocking the closure, one or more battery packs can be inserted into the down tube from below. If the down tube cannot or should not be completely filled with battery packs, it is provided that a resilient contact is provided in the inside of the down tube, which on the one hand ensures permanent contact with the batteries, but on the other hand also keeps the batteries resilient.
Erfindungsgemäß ist ferner zum Bestücken des Unterrohres mit den Batterien vorgesehen, daß das Hinterrad über sei- nen Hinterradausleger aus der Normalposition verschwenkbar ist und auf diese Weise durch einfache manuelle Bedienung das Unterrohr mit den Batterien bestückt werden kann. Hierzu ist ferner erfindungsgemäß vorgesehen, daß der Hinterradausleger mit dem Unterrohr, der ein Teil des Fahrradrahmens darstellt, über einen Stoßdämpfer federnd verbunden ist, der gegebenenfalls zum Wechseln des Batte- riepacks von dem Hinterrad und/oder von dem Unterrohr entriegelt werden kann.According to the invention, it is further provided for equipping the down tube with the batteries that the rear wheel can be pivoted out of the normal position via its rear wheel arm, and in this way the down tube can be equipped with the batteries by simple manual operation. For this purpose, it is further provided according to the invention that the rear wheel boom is connected to the down tube, which forms part of the bicycle frame, via a shock absorber, which can be used to change the battery. riepacks can be unlocked from the rear wheel and / or from the down tube.
Eine andere Ausführungsform sieht erfindungsgemäß vor, daß ein nicht-federnder Fahrradrahmen verwendet wird. In diesem Fall ist der Hinterradausleger mit einem weiteren Rahmenelement, nämlich dem Sattelrohr zwischen Ober- und Unterrohr versehen. Maßgeblich für die Erfindung ist jedoch, daß das Tretlager entweder oberhalb oder unterhalb des Unterrohres angeordnet ist und nicht im Inneren, da das Unterrohr selbst zur Aufnahme der Batterien dient. Das Tretlagerrohr wird gegenüber der normalen Diamatgeo- metrie aus dem Schnittpunkt von Sattel- und Unterrohr verlegt und ermöglicht somit die Bestückung mit Batterien bzw. Batteriekartuschen.Another embodiment provides according to the invention that a non-resilient bicycle frame is used. In this case, the rear wheel boom is provided with a further frame element, namely the seat tube between the upper and lower tube. It is decisive for the invention, however, that the bottom bracket is arranged either above or below the down tube and not inside, since the down tube itself serves to hold the batteries. Compared to the normal diamond geometry, the bottom bracket tube is laid from the intersection of the saddle and down tube, thus enabling it to be equipped with batteries or battery cartridges.
Die Kapazität der Batterien ist üblicherweise beschränkt, so daß für diesen Fall vorgesehen ist, daß leistungsstärkere Batterien in das Unterrohr eingeschoben werden können bzw. durch eine In-Serie-Schaltung von mehreren Batterie-Packs die Kapazität des Elektromotors erhöht werden kann. Dies macht insbesondere dann Sinn, wenn größere Strecken zurückgelegt werden müssen. Hierzu ist fernerhin vorgesehen, daß eine Aufbewahrungsmöglichkeit in Form einer Halterung an dem Unterrohr angeordnet ist. In diese Halterung können gegebenenfalls Batteriepacks verbracht werden, die im Bedarfsfalle in das Unterrohr zusätzlich eingeschoben werden können oder gegen leere Akkus im Unterrohr ausgetauscht werden können. Sollte diese Halterung nicht für Energiepacks verwendet werden, könnte sie beisp. für die Aufbewahrung von einem Schalenkoffer die- nen, was für Stadtkuriere von erheblichem Vorteil ist. Die Ersatzakkus können sowohl ausgetauscht als auch zugeschaltet werden, was die Reichweite ohne Austausch des Innenakkus vergrößert.The capacity of the batteries is usually limited, so that in this case it is provided that more powerful batteries can be inserted into the down tube or the capacity of the electric motor can be increased by connecting several battery packs in series. This makes particular sense when larger distances have to be covered. For this purpose, it is further provided that a storage option in the form of a holder is arranged on the down tube. If necessary, battery packs can be placed in this holder, which can be pushed into the down tube if necessary or can be exchanged for empty rechargeable batteries in the down tube. If this holder is not used for energy packs, it could for example. serve to store a shell case, which is a considerable advantage for city couriers. The replacement batteries can be replaced as well as switched on, which increases the range without replacing the inner battery.
Da die Kapazität der Batterien beschränkt ist, müssen diese regelmäßig aufgeladen werden. Hierzu bieten sich entweder übliche Verfahren an, daß heißt, die externe Aufladung der Batterien oder aber eine interne Batterieaufladung durch eine Spannungsanlegung an die sich in dem Unterrohr befindlichen Batterien bzw. Batteriepacks.Since the capacity of the batteries is limited, they must be charged regularly. For this purpose either conventional methods are available, that is, the external charging of the batteries or an internal battery charging by applying a voltage to the batteries or battery packs located in the down tube.
Die Erfindung weist daher zusammenfassend folgende Vorteile auf:The invention therefore has the following advantages in summary:
die Energieversorgungseinrichtung, nämlich die Energiepacks, sind nahe des Schwerpunkts des Fahrrades angeordnet,the energy supply device, namely the energy packs, are arranged near the center of gravity of the bicycle,
- die Energiepacks sind nicht frei zugänglich für jedermann, da hierzu erst in einer bevorzugten - gefederten - Ausführungsform das Hinterrad abgewinkelt werden muß,the energy packs are not freely accessible to everyone, since the rear wheel must first be angled in a preferred, spring-loaded embodiment,
die Energieversorgungseinrichtung ist für Dritte nicht sichtbar, wodurch das Fahrrad optisch nicht durch den Energiepack verändert wird,the energy supply device is not visible to third parties, so that the bike is not visually changed by the energy pack,
die Schwerpunktverteilung am Fahrrad wird durch die Gewichtszunahme nahe am optimalen Schwerpunkt des Fahrrades (dem Tretlager) durch den Energiepack be- günstigt, dem Fahrrad stehen nach wie ' vor durch die nicht sichtbare Unterbringung der Energiepacks sämtliche Zusatzverstaumöglichkeiten zur Verfügung, daß heißt, weder die Schutzbleche, noch die Fahrradtaschen, noch irgendwelche anderen äußerlich sichtbaren Teile des Fahrrades werden durch den Energiepack beeinträchtigt, so daß diese Flächen bzw. Örtlichkeiten des Fahrrades anderen Möglichkeiten zur Verfügung stehen, wie z.B. einem Gepäckträger,the distribution of the center of gravity on the bicycle is favored by the weight gain close to the optimal center of gravity of the bicycle (the bottom bracket) by the energy pack, bicycle stand still 'in front by the invisible accommodation of the energy packs all Zusatzverstaumöglichkeiten available, that is, neither the guards nor the bike bags, nor any other externally visible parts of the bicycle are affected by the power pack, so that these areas or Locations of the bike are available for other options, such as a luggage rack,
- das Fahrrad kann, wenn Batteriepack und Motor entfernt sind als „normales" Fahrrad verwendet werden, da es sich weder durch Gewicht noch durch eine optische Veränderung von einem herkömmlichen Fahrrad unterscheidet .- The bicycle can be used as a "normal" bicycle when the battery pack and motor are removed, since it does not differ from a conventional bicycle in terms of weight or optical changes.
Weitere vorteilhafte Maßnahmen sind in den übrigen Unteransprüchen beschrieben. Die Erfindung wird anhand der folgenden Figuren und einem Ausführungsbeispiel näher beschrieben; es zeigt:Further advantageous measures are described in the remaining subclaims. The invention is described in more detail with reference to the following figures and an embodiment; it shows:

Figur 4 eine Ausführungsform gemäß FigurFigure 4 shows an embodiment according to Figure
3 mit oberhalb des Unterrohres angeordneten Tretlager.3 with bottom bracket arranged above the down tube.
Die Figur 1 zeigt ein Fahrrad, bestehend aus einem Oberrohr 10 und einem Unterrohr 4, welches mit einem Tretla- ger 3 unterhalb des Unterrohres 4 versehen ist. An dem Tretlager 3 ist ein Kettenblatt 2 angeordnet, welches in bekannter Art und Weise mit dem Hinterrad 11 bzw. dem - nicht dargestellten - Kettenblatt des Hinterrades 11 versehen ist. An dem Hinterrad 11 ist ferner ein Elektromo- tor 1 angeordnet, der im Bedarfsfalle dem Fahrrad zuschaltbar ist. Hierzu ist (nicht dargestellt) am Fahrradlenker eine Zuschalteinrichtung bzw. eine Kontrolleinrichtung für den Elektromotor vorgesehen, einschließlich Geschwindigkeitsgeber.FIG. 1 shows a bicycle, consisting of an upper tube 10 and a down tube 4, which is provided with a bottom bracket 3 below the down tube 4. A chainring 2 is arranged on the bottom bracket 3 and is provided in a known manner with the rear wheel 11 or the chainring of the rear wheel 11 (not shown). An electric motor 1 is also arranged on the rear wheel 11 and can be switched on to the bicycle if necessary. For this purpose, a connection device or a control device for the electric motor, including a speed sensor, is provided on the bicycle handlebar.
Das Hinterrad 11 ist mit dem Unterrohr 4 über einen Hinterradausleger 8 verbunden, der mit dem Unterrohr 4 gelenkig über ein Gelenk 12, welches oberhalb des Unterrohres 4 angeordnet ist, verbunden ist. Ferner ist der Hinterradausleger 8 über einen Stoßdämpfer 7 mit dem Unter- röhr 4 verbunden, so daß der Hinterradausleger 8 bzw. das Hinterrad 11 federnd gelagert ist. Der Stoßdämpfer 7 ist lösbar mit dem Hinterradausleger 8 versehen, so daß er gegebenenfalls aus der Verbindung geklappt werden kann und das Hinterrad 11 über den Hinterradausleger 8 bzw. dessen Gelenk 12 frei beweglich ist.The rear wheel 11 is connected to the down tube 4 via a rear wheel arm 8, which is connected to the down tube 4 in an articulated manner via a joint 12 which is arranged above the down tube 4. Furthermore, the rear wheel arm 8 is connected to the lower tube 4 via a shock absorber 7, so that the rear wheel arm 8 or the rear wheel 11 is spring-mounted. The shock absorber 7 is detachably provided with the rear wheel boom 8 so that it can be folded out of the connection if necessary and the rear wheel 11 is freely movable via the rear wheel arm 8 or its joint 12.
Das Unterrohr 4 ist - vergleiche Figur 2 - hohl, und beherbergt in seinem Inneren mindestens einen Batteriepack, der der Energieversorgung des Elektromotors 1 dient. Zum Einführen des Batteriepacks 5 in das Unterrohr 4 wird an dem unteren Ende des Unterrohres 4 eine Veschlußkappe 6 manuell durch Drehen bzw. Endarretierung entfernt und der Batteriepack eingeführt. Der Verschluß 6 dient gleichzei- tig als Kontaktmittel für den Batteriepack 5. Durch Wegklappen des Hinterrades 11 aus der gemeinsamen Achse „ Unterrohres-Hinterrades" , ist die Einführöffnung in das Unterrohr 4 frei zugänglich.The down tube 4 is hollow - compare FIG. 2 - and houses at least one battery pack in its interior, which serves to supply energy to the electric motor 1. To insert the battery pack 5 into the down tube 4, a closure cap 6 is manually removed at the lower end of the down tube 4 by turning or locking it, and the battery pack is inserted. The closure 6 serves at the same time as a contact means for the battery pack 5. By folding the rear wheel 11 away from the common axis “down tube rear wheel”, the insertion opening into the down tube 4 is freely accessible.
Um zu verhindern, daß Dritte sich an dem Unterrohr mit seinem darin befindlichen Energiepack zu schaffen machen, kann vorgesehen sein, daß der Verschluß 6 mit einem Sicherheitsschloß gesichert ist. Zusätzlich oder alternativ ist vorgesehen, daß der Stoßdämpfer 7 über eine Verschließeinrichtung mit dem Hinterradausleger 8 kontrol- lierbar, lösbar verbindbar ist. Hierzu läßt sich ein einfacher Schließmechanismus mit Sicherheitsschlüssel in dem Verbindungsmittel zwischen Stoßdämpfer 7 und Hinterradausleger 8 bzw. Unterrohr 4 anbringen (nicht dargestellt) .In order to prevent third parties from tampering with the down tube with its energy pack located therein, it can be provided that the closure 6 is secured with a security lock. Additionally or alternatively, it is provided that the shock absorber 7 can be connected to the rear wheel arm 8 in a controllable, detachable manner via a locking device. For this purpose, a simple locking mechanism with a safety key can be attached in the connecting means between the shock absorber 7 and the rear wheel arm 8 or down tube 4 (not shown).
Die Figur 3 zeigt ein Tretlager 3, welches oberhalb des Unterrohres 4 angeordnet ist. Der Fahrradrahmen ist in diesem Fall nicht-gelenkig ausgebildet, da der Hinterradausleger 8 als aus Sitzstrebe und einem weiteren Rahmenelement 9, nämlich dem Sattelrohr, sowie einer Ketten- strebe 8a bestehend, ausgebildet ist. Das Sattelrohr 9 verbindet Unterrohr 4 und Oberrohr 10 zu einem gemeinsamen Hinterbau.FIG. 3 shows a bottom bracket 3, which is arranged above the down tube 4. In this case, the bicycle frame is non-articulated, since the rear wheel arm 8 consists of a seat stay and a further frame element 9, namely the seat tube, and a chain strut 8a, is formed. The seat tube 9 connects the lower tube 4 and the upper tube 10 to a common rear triangle.
Eine andere Ausfuhrungsform ist m der Figur 4 darge- stellt, in der das Tretlager 3 unterhalb des Unterrohres 4 angeordnet ist und im übrigen der Hinterradausleger 8 ebenso wie in der Figur 3 nicht-gelenkig ausgebildet st. Auch durch die Ausfuhrungsform wie m der Figur 3 und 4 beschrieben, besteht die Möglichkeit, von unten das Un- terrohr 4 mit dem Batteriepack zu bestucken.Another embodiment is shown in FIG. 4, in which the bottom bracket 3 is arranged below the down tube 4 and, in the rest of the case, the rear wheel arm 8, as in FIG. 3, is non-articulated. The embodiment as described in FIGS. 3 and 4 also makes it possible to equip the down tube 4 with the battery pack from below.
Ferner ist vorgesehen, daß das Unterrohr 4 mit einer - nicht dargestellten - Halterung zur Aufnahme von weiteren Batteriepacks bzw. Batteriekartuschen vorgesehen sind. Diese Halterung kann alternativ auch dazu verwendet wer- den, Schalenkoffer zur Aufbewahrung von Gegenstanden, quasi als Gepackstander, aufzunehmen.It is further provided that the down tube 4 is provided with a holder (not shown) for receiving additional battery packs or battery cartridges. As an alternative, this holder can also be used to hold shell cases for storing objects, more or less as a luggage stand.
Der Vorteil des nah am Tretlager liegenden Batteriepacks besteht darin, daß durch die Anordnung am tiefsten Punkt des Rahmens ein sehr tiefer Schwerpunkt geschaffen wird, der das Handlmg des Fahrrades deutlich verbessert. Durch die erfmdungsgemaße Losung der Anordnung der Batterien im Innern des Unterrohres 4 wird eine einfache Möglichkeit zum Wechseln der Akkus geschaffen, so daß innerhalb weniger Minuten ohne zusätzliches Werkzeug die Batterie- kartuschen ausgetauscht werden können.The advantage of the battery pack lying close to the bottom bracket is that the arrangement at the lowest point of the frame creates a very low center of gravity, which significantly improves the handling of the bicycle. The solution according to the invention of the arrangement of the batteries in the interior of the down tube 4 creates a simple possibility for changing the batteries, so that the battery cartridges can be replaced within a few minutes without additional tools.
Es ist ebenso möglich, die Kartuschen nicht von unten in das Unterrohr einzuschieben, sondern durch Einschieben der Kartuschen von oben m das Unterrohr für eine Bestuk- kung mit Batterien zu sorgen. Hierzu ist - nicht darge- stellt - vorgesehen, daß das Oberrohr 10 am Steuerrohr mit einem mechanischem Verschluß ausgestattet ist. Durch einfaches Entriegeln des Verschlusses läßt sich ein Bestücken des Unterrohres 4 mit Batteriekartuschen ermöglichen. It is also possible not to insert the cartridges into the down tube from below, but instead to insert batteries into the down tube by inserting the cartridges from above. This is - not shown provides - provided that the top tube 10 is equipped with a mechanical closure on the head tube. By simply unlocking the closure, it is possible to equip the down tube 4 with battery cartridges.
