Der Sitz 11 hat eine herausklappbare kleine Sitzfläche all'.The seat 11 has a fold-out small seat all '.

Er ist um die vertikale Achse 12 von der in Fig. 9 gezeichneten normalen Fahrtstellung in die in Fig. 10 gezeichnete um 1800 schwenkbar sowie in beiden dargestellten Stellungen arretierbar. Dadurch wird die Möglichkeit geschaffen, daß bei einem Personentransport beim Abholen der behinderten Person der Fahrer bequem auf dem Sessel 11 fahren kann, jedoch beim Transportieren der abzuholenden Person diese in bequemer Weise, wie in Fig. 10 angedeutet, im Sessel transportiert werden kann, während der Fahrer die kleine Sitzfläche 11' benutzen kann. In diesem Fall sind herausklappbare Fußstützen 25 nützlich.It is about the vertical axis 12 from the normal drawn in FIG Driving position in the drawn in Fig. 10 can be pivoted around 1800 and in both shown Lockable positions. This creates the possibility that when people are being transported when picking up the disabled person, the driver can comfortably ride on the chair 11, however, when transporting the person to be picked up this in a convenient manner, such as indicated in Fig. 10, can be transported in the chair, while the driver the small seat 11 'can use. In this case, there are fold-out footrests 25 useful.

Die Figuren 11 bis 14 zeigen eine weitere Variante des erfindungsgemäß ausgebildeten kleinen Elektrofahrzeugesw Der Sitz 11A ist als kistenartiger Hocker ausgebildet, und zwar so, daß er, wie aus Fig. 11 ersichtlich, eine Sitzfläche für den Fahrer bildet, wobei der Innenraum llA' des Hockers 11A als Gepäckraum zum Transport von kleinen Gegenständen geeignet ist.Figures 11 to 14 show a further variant of the invention trained small electric vehicle The seat 11A is a box-like stool formed, in such a way that, as can be seen from Fig. 11, a seat for forms the driver, the interior 11A 'of the stool 11A as a luggage space for transport of small objects.

Wird der Hocker 11A in die in Fig. 12 gezeigte umgekehrte Stellung gebracht, können in dem nunmehr vorhandenen oben offenen Gepäckraum größere bzw. höhere Gegenstände transportiert werden. Für diesen Betriebszustand ist es besonders nützlich, wenn die Länge der Lenkstange 3 teleskopartig veränderlich und dadurch deren jeweiligen Anforderungen anpaßbar ist. In diesem Fall wird die Lenkstange 3 in der senkrechten-Stellung arretiert.When the stool 11A is in the inverted position shown in FIG brought larger or larger higher objects are transported. It is special for this operating state useful when the length of the handlebar 3 telescopically variable and thereby their respective requirements is customizable. In this case it will the handlebar 3 locked in the vertical position.

zweckmäßigerweise ist die Lenkstange 3 auch nach vorn in eine schräg aufwärts gerichtete Lage schwenkbar, wie dies in Fig. 13 angedeutet ist. In dieser Stellung ist es möglich, daß das Elektrofahrzeug von einer vorausgehenden Person wie an einer Deichsel geführt wird, jedoch aus eigener Kraft mit der jeweils eingestellten Geschwindigkeit fährt. In diesem Fall steht zur Unterbringung der mitzuführenden Gegenstände nicht nur de Innenraum llA' des nach unten geklappten, in den Fußraum des Elektrofahrzeuges hineingestellten Hockers llA zur Verfügung, sondern es kann, wie durch das Gepäckstück 27 angedeutet, fast die gesamte Länge des Fahrzeuges als Ladefläche benutzt werden. Außerdem steht durch den Wegfall des Fahrergewichts eine zusätzliche Lastreserve zur Verfügung.Appropriately, the handlebar 3 is also obliquely forward upwardly directed position can be pivoted, as indicated in FIG. 13. In this Position it is possible for the electric vehicle to be driven by a previous person as is guided on a drawbar, but on its own with the respectively set one Speed is driving. In this case it is available to accommodate those to be carried Objects not just de interior llA 'of the folded down, in the footwell the stool llA placed in it, but it can, as indicated by the item of luggage 27, almost the entire length of the vehicle as Loading area can be used. In addition, there is a additional load reserve available.

Da das Umklappen der Lenkstange 3 von der in Fig. ll und 12 gezeigten Stellung in die in Fig. 13 gezeigte Stellung praktisch ohne Zeitverlust in einfacher Weise möglich ist und auch gegebenenfalls die Veränderung der Lage des Hockers ll schnell und einfach vorgenommen werden kann, besteht die interessante Möglichkeit, daß der Fahrer zum Abholen der Last schnell und bequem in der in Fig. ll gezeigten Stellung fahren kann und dann die abzuholende Last in der in Fig. 13 gezeigten Stellung transportieren kann.Since the folding of the handlebar 3 from that shown in Figs Position in the position shown in Fig. 13 in a simple manner practically without loss of time Way is possible and also, if necessary, the change in the position of the stool ll can be done quickly and easily, there is the interesting possibility that the driver to pick up the load quickly and conveniently in the one shown in Fig. ll Position can move and then the load to be picked up in the position shown in FIG can transport.

Bei Nichtgebrauch nimmt das in den Fig. 11 bis 13 dargestellte Elektrofahrzeug nach Umlegen der Lenkstange 3 nur einen vertbältnismäßig kleinen Raum ein. Es kann daher bequem abgestellt werden, im Gepäckraum von PKW's mitgenommen werden und auch - bevorzugt in aufrechter Stellung -in verhältnismäBig kleinen Personenaufzügen transportiert werden. Da die Lenkstange 3 in der heruntergeklappten Stellung fixierbar ist, kann sie als Handgriff benutzt werden, was insbesondere beim Verladen in PKW's bzw. beim Aufstellen in Personenaufzügen von Bedeutung ist.When not in use, the electric vehicle shown in FIGS. 11 to 13 takes after turning the handlebar 3 only a relatively small space. It can can therefore be conveniently parked, taken in the luggage compartment of cars and also - preferably in an upright position -in relatively small Passenger elevators are transported. Since the handlebar 3 in the folded down Position can be fixed, it can be used as a handle, which in particular is important when loading into cars or when setting up in passenger lifts.
