Dementsprechend ist der Herstellungsaufwand für derartige Elektro-Rollstühle sehr hoch. Dabei ist nicht nur die reine Herstellung zu beachten, sondern auch der Aufwand, der bei Reparaturen, Umbaumaßnahmen oder Ähnlichem erforderlich ist. Im Extremfall muss der gesamte Elektro-Rollstuhl mehr oder weniger vollständig demontiert werden, um einzelne Baukomponenten auszutauschen, zu ersetzen und zu ergänzen.Electric wheelchairs are technically sophisticated products that carry a variety of individual components, such as Drive motors, gears, batteries, control and Control units or the like. Accordingly, the Manufacturing effort for such electric wheelchairs very much high. Not only the pure production has to be considered, but also the effort involved in repairs, remodeling or the like is required. In extreme cases, the Entire electric wheelchair more or less completely dismantled to replace individual components, to replace and supplement.

Der Erfindung liegt die Aufgabe zugrunde, einen Elektro-Rollstuhl der eingangs genannten Art zu schaffen, welcher bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit unter Vermeidung der Nachteile des Standes der Technik einfach montierbar und demontierbar ist und sich durch ein hohes Maß an universeller Einsetzbarkeit auszeichnet. The invention has for its object an electric wheelchair of the type mentioned at the beginning, which with a simple structure and simple, inexpensive to manufacture while avoiding the disadvantages of the prior art Technology is easy to assemble and disassemble characterized by a high degree of universal applicability.

Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Hauptanspruchs gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention, the object is achieved by the combination of features of the main claim, the sub-claims show further advantageous embodiments of the invention.

Erfindungsgemäß ist somit vorgesehen, dass der Fahrwerksrahmen einen rechten Seitenrahmen und einen linken Seitenrahmen umfasst, welche lösbar miteinander verbunden sind und im Wesentlichen zueinander spiegelbildlich aufgebaut sind.It is thus provided according to the invention that the chassis frame a right side frame and a left side frame comprises, which are releasably connected to each other and essentially are mirror images of each other.

Durch die erfindungsgemäß vorgesehene Ausgestaltung des Fahrwerksrahmens ergeben sich eine Vielzahl von Vorteilen.Due to the inventive design of the Chassis frames result in a number of advantages.

Durch die Verwendung zweier Seitenrahmen kann der Bearbeitungs- und Montageaufwand erheblich gesenkt werden. Die beiden Rahmenteile der Seitenrahmen sind, da sie im Wesentlichen spiegelbildlich ausgestaltet sind, kostengünstig herstellbar. Durch die lösbare Verbindung der beiden Seitenrahmen ist es möglich, Baugruppen oder Elemente, die sich zwischen den Seitenrahmen in dem Fahrwerksrahmen befinden, einfach auszubauen oder zu montieren. So ist es beispielsweise beim Anbau von elektrischen Sitzverstellantrieben möglich, die beiden Seitenrahmen in einfachster Weise voneinander zu trennen. Besonders vorteilhaft ist es dabei, wenn die Seitenrahmen lösbar miteinander verschraubt sind.By using two side frames, the editing and assembly effort can be significantly reduced. The two Frame parts of the side frames are, as they are essentially are mirror images, inexpensive to manufacture. Through the detachable connection of the two side frames it is possible to assemblies or elements that are between the side frame is in the chassis frame, simply remove or assemble. For example, it is possible when installing electric seat adjustment drives, the two side frames in the simplest way from each other separate. It is particularly advantageous if the side frame are detachably screwed together.

Ergänzend zu der spiegelbildlichen Ausgestaltung können lediglich einzelne Bauelemente, beispielsweise Bremshebel, Steckerlaschen oder Ähnliches, in asymmetrischer Anordnung vorgesehen sein.In addition to the mirror image configuration, only individual components, for example brake levers, Plug tabs or the like, in an asymmetrical arrangement be provided.

Dabei erweist es sich als besonders günstig, wenn der rechte und der linke Seitenrahmen mittels horizontaler, quer zur Fahrtrichtung angeordneter Steckrohre lösbar miteinander verbunden sind. Die beiden Steckrohre bzw. die entsprechenden zum Einstecken vorgesehenen Rohrenden der Seitenrahmen können dabei sowohl die Lagerung für den Sitzrahmen als auch für Antriebskomponenten der Hinterräder bilden. So kann beispielsweise das hintere Steckrohr zur Getriebelagerung einer Hinterradschwinge dienen, während das vordere Steckrohr einen Stützbereich des Sitzrahmens bilden kann.It proves to be particularly favorable if the right one and the left side frame using horizontal, transverse to Plug-in tubes arranged in the direction of travel releasably together are connected. The two plug-in tubes or the corresponding ones for inserting the pipe ends of the side frames can both the storage for the seat frame as well form for drive components of the rear wheels.

Die Hinterradschwinge ist dabei als Längslenker ausgebildet. Sie kann als Blechteil, Blechbiegeteil oder Blechstanzteil ausgebildet sein und trägt bevorzugter Weise an ihrem hinteren Ende eine Antikipprolle. Weiterhin ist es möglich, zwischen der Hinterradschwinge und dem jeweiligen Seitenrahmen ein Federungs- und/oder Dämpfungselement zwischenzuschalten.The rear swing arm is designed as a trailing arm. It can be used as a sheet metal part, bent sheet metal part or stamped sheet metal part be trained and preferably carries on their rear End of an anti-tip roll. It is also possible to choose between the rear swing arm and the respective side frame to interpose a suspension and / or damping element.

Bei der erfindungsgemäßen Ausgestaltung des Elektro-Rollstuhls ist es somit möglich, an der Hinterradschwinge sowohl das jeweilige Hinterrad, als auch dessen Antriebskomponenten (Motor und/oder Getriebe) zu montieren. Die Hinterradschwinge weist bevorzugt ein Lagerrohr mit beispielsweise Kunststoffgleitlagern auf, welches auf das bereits erwähnte Getriebelagerrohr (hinteres Steckrohr) aufgeschoben werden kann. Zur seitlichen Fixierung kann ein Begrenzungsrohr dienen. Als bevorzugt erweist es sich hierbei, dass erfindungsgemäß die Montage der Hinterradschwinge in einfachster Weise an dem jeweiligen Seitenrahmen erfolgen kann. Durch die Zuordnung der beiden Seitenrahmen zueinander ergibt sich dann auch eine entsprechende Zuordnung und Fixierung der beiden Hinterradschwingen. Im bevorzugten Falle kann die gesamte Montage der Hinterradschwinge mit nur einer einzigen Schraubverbindung erfolgen, während sämtliche anderen Komponenten als Steckverbindungen ausgebildet sind.In the embodiment of the electric wheelchair according to the invention it is therefore possible to use the rear swing arm both the respective rear wheel and its drive components (Engine and / or gearbox). The rear swing arm preferably has a bearing tube with, for example Plastic plain bearings, which on the already mentioned Gearbox bearing tube (rear push tube) can be pushed on can. A boundary tube can be used for lateral fixation. It has proven to be preferred that the invention the assembly of the rear swing arm in the simplest way can be done on the respective side frame. By assignment the two side frames to each other then result a corresponding assignment and fixation of the two Rear wings. In the preferred case, the entire Assembly of the rear swing arm with just one Screw connection done while all other components are designed as plug connections.

Erfindungsgemäß ist es weiterhin möglich, an der Hinterradschwinge auch den zur Übertragung der Antriebsenergie erforderlichen Motorstecker vorzusehen.According to the invention, it is also possible to use the rear swing arm also those necessary for the transmission of the drive energy Provide motor connector.

Besonders günstig ist es, wenn erfindungsgemäß auf dem Fahrwerksrahmen ein den Sitz tragender Sitzrahmen gelagert ist, der um eine horizontale Achse kippbar ist. Es ist somit möglich, die Neigung der Sitzfläche in sehr einfacher Weise einzustellen.It is particularly favorable if, according to the invention, on the chassis frame a seat frame supporting the seat is mounted, which can be tilted around a horizontal axis. It is therefore possible the inclination of the seat in a very simple way adjust.

Der Sitzrahmen ist an dem erfindungsgemäßen Elektro-Rollstuhl bevorzugter Weise so gelagert, dass ein rückwärtiger Lagerbereich an dem jeweiligen Seitenrahmen ausgebildet ist, während der vordere Bereich des Sitzrahmens über den bereits erwähnten Stützbereich abgestützt ist. Dieser Stützbereich kann bevorzugter Weise in Form eines verstellbaren Teleskoprohres ausgebildet sein, sodass es auf einfachste Weise möglich ist, die Neigung der Sitzfläche den Bedürfnissen des Rollstuhlbenutzers anzupassen.The seat frame is on the electric wheelchair according to the invention preferably stored so that a rear Storage area formed on the respective side frame while the front of the seat frame is over the already mentioned support area is supported.

Schraffuren von geschnittenen Teilen.The graphic representations are CAD drawings. As a result, hidden lines are penetrations or similar, not dashed. Also missing Hatching of cut parts.

Wie sich aus den Fig. 1 und 2 ergibt, umfasst der erfindungsgemäße Elektro-Rollstuhl jeweils zwei Vorderräder 1, welche jeweils um eine vertikale Achse drehbar mittels einer Gabel 22 gelagert sind, so wie dies aus dem Stand der Technik bekannt ist.As can be seen from FIGS. 1 and 2, the invention comprises Electric wheelchair two front wheels 1, which are each rotatable about a vertical axis by means of a Fork 22 are mounted, as is the case in the prior art is known.

Der Rollstuhl umfasst weiterhin zwei nicht-lenkbare Hinterräder 2, welche jeweils an einer Hinterradschwinge 15 gelagert sind. Die Hinterradschwinge 15 ist um eine Lagerung 14 des jeweiligen Seitenrahmens 4 bzw. 5 schwenkbar gelagert. Sie ist plattenförmig aufgebaut und dient zur Lagerung einer Antriebseinheit 19, welche einen Motor sowie ein Getriebe umfassen kann.The wheelchair also includes two non-steerable rear wheels 2, which are each mounted on a rear swing arm 15 are. The rear swing arm 15 is about a bearing 14 of the respective side frame 4 or 5 pivotally mounted. It is plate-shaped and serves to store one Drive unit 19, which has a motor and a transmission may include.

An einem Lagerpunkt 23 ist an der Schwinge ein Federungsund/oder Dämpfungselement 17 angeordnet, dessen oberer Endbereich gelenkig mit einem Lagerbock 24 verbunden ist, welcher wiederum an einem Oberrohr 12 des jeweiligen Seitenrahmens 4 bzw. 5 befestigt ist.At a bearing point 23 is a suspension and / or on the rocker Damping element 17 arranged, the upper end region is pivotally connected to a bearing block 24, which again on an upper tube 12 of the respective side frame 4 or 5 is attached.

Die beiden Seitenrahmen 4 und 5 bilden einen gemeinsamen Fahrwerksrahmen, der in der Draufsicht in Fig. 6 dargestellt ist. Hierzu umfassen die beiden Seitenrahmen 4, 5 jeweils ein Oberrohr 12 und ein Unterrohr 13 (siehe auch Fig. 3 bis 5). Im vorderen Bereich sind das Oberrohr 12 und das Unterrohr 13 direkt miteinander verbunden, während sie im Bereich der Lagerung der Hinterradschwinge (Lagerung 14) entsprechend abgestrebt sind. Am hinteren Ende ist das Oberrohr 12 um 90° gebogen, sodass sich ein hinterer Anschlussbereich 21 ergibt, auf welchen eine Schlaufe eines Rückhaltegurtes aufschiebbar ist. In entsprechender Weise kann der gebogene vordere Bereich des jeweiligen Oberrohrs 12 einen vorderen Anschlussbereich 20 bilden, an den ein vorderer Rückhaltegurt anhängbar ist. Die beiden Rückhaltegurte dienen dazu, den Elektro-Rollstuhl beim Transport, beispielsweise in einem Fahrzeug, zu sichern.The two side frames 4 and 5 form a common one Chassis frame, which is shown in plan view in Fig. 6 is. For this purpose, the two side frames 4, 5 each include an upper tube 12 and a down tube 13 (see also Fig. 3 to 5). In the front area are the top tube 12 and the down tube 13 directly connected to each other while in the area the bearing of the rear swing arm (bearing 14) accordingly are striving for. At the rear end is the top tube 12 bent by 90 ° so that a rear connection area 21 results on which a loop of a restraint belt can be pushed is. In a corresponding way, the curved front area of the respective top tube 12 a front Form connection area 20 to which a front restraint belt can be attached. The two restraint belts are used to the electric wheelchair during transport, for example in one Secure vehicle.

Wie sich beispielsweise aus einem Vergleich der Fig. 4 und 6 ergibt, sind die beiden Seitenrahmen 4 und 5 jeweils ineinander steckbar. Dies erfolgt durch ein (in der Fig. 6 nicht direkt sichtbares) innen liegendes vorderes Steckrohr 8 sowie ein hinteres Steckrohr 9, welches im Bereich der Lagerung 14 die Abstützung oder Strebe des Seitenrahmens durchdringt (siehe Fig. 5 und 6).As can be seen, for example, from a comparison of FIGS. 4 and 6 results, the two side frames 4 and 5 are each one in the other pluggable. This is done by a (in FIG. 6 not directly visible) inside front tube 8 and a rear plug tube 9, which in the area of storage 14 penetrates the support or strut of the side frame (see Figs. 5 and 6).

Durch den Aufbau des Fahrwerksrahmens, welcher aus den beiden Seitenrahmen 4, 5 zusammengesetzt ist, ist es möglich, die Breite des Fahrwerksrahmens zu variieren, indem entsprechende Distanzelemente oder Distanzstücke bzw. Zwischenelemente zwischen die beiden Seitenrahmen 4, 5 montiert werden. Dies ist in einfachster Weise durch entsprechende Verlängerung der Steckrohre 8, 9 und durch Aufschieben von Distanzhülsen möglich.By building the chassis frame, which consists of the two Side frame 4, 5 is composed, it is possible vary the width of the undercarriage frame by appropriate Spacers or spacers or intermediate elements can be mounted between the two side frames 4, 5. This is done in the simplest way by appropriate extension the plug-in tubes 8, 9 and by pushing on spacer sleeves possible.

Wie die Fig. 6 zeigt, wird beim Zusammenbau der beiden Seitenrahmen zwischen den vorderen Anschlussbereichen 20 beim Einschieben des (in Fig. 6 nicht sichtbaren) vorderen Steckrohrs 8 eine Hülse 25 aufgeschoben bzw. zwischengelegt, an welcher ein teleskopischer Stützbereich 11 für einen Sitzrahmen 7 befestigt ist. Das Teleskoprohr des Stützbereichs 11 ist mittels eines Hebels 26 einstellbar, um den Sitzrahmen 7 um eine horizontale Achse 6, welche an einem hinteren Lagerbereich 10 des Oberrohrs 12 ausgebildet ist, zu verschwenken. Ein Vergleich der Fig. 1 und 2 zeigt den unterschiedlichen Schwenk- oder Kantel-Zustand.6 shows, when assembling the two side frames between the front connection areas 20 at Insert the front plug-in tube (not visible in FIG. 6) 8 a sleeve 25 pushed on or interposed which is a telescopic support area 11 for a seat frame 7 is attached. The telescopic tube of the support area 11 is adjustable by means of a lever 26 around the seat frame 7 about a horizontal axis 6, which on a rear Bearing area 10 of the top tube 12 is designed to pivot. A comparison of FIGS. 1 and 2 shows the different Swivel or tilt condition.

Erfindungsgemäß kann der Stützbereich 11 auch elektrisch verstellbar sein, beispielsweise mittels eines Getriebes oder eines Linearantriebs.According to the invention, the support area 11 can also be electrical be adjustable, for example by means of a gear or a linear actuator.

Der Sitzrahmen 7 ist, wie sich aus der Draufsicht der Fig. 7 ergibt, aus zwei Sitzrahmenhälften 16 zusammengesetzt, welche ebenfalls gesteckt und verschraubt werden können. Somit kann auch der Sitzrahmen 7, der einen im Einzelnen nicht dargestellten Sitz 3 trägt, in einfacher Weise zusammengebaut bzw. demontiert werden. Im Übrigen entspricht der Sitz 3 mit seinem Sitzpolster, seinen Armlehnen, seinen Seitenteilen sowie seiner Rückenlehne im Wesentlichen den aus dem Stand der Technik bekannten Anordnungen, sodass auf weitere detaillierte Beschreibungen an dieser Stelle verzichtet werden kann.The seat frame 7 is, as can be seen from the top view of FIG. 7 results, composed of two seat frame halves 16, which can also be inserted and screwed. Consequently can also the seat frame 7, the one in detail shown seat 3 carries, assembled in a simple manner be dismantled. Otherwise, the seat corresponds 3 with its seat cushion, armrests, side panels and its backrest essentially the one from the Arrangements known in the art, so that further detailed descriptions are omitted here can.

Der Sitzrahmen 7 ist, da er aus den beiden Sitzrahmenhälften 16 zusammengebaut ist, in seiner Breite sehr einfach variabel. Hierfür ist es lediglich erforderlich, entsprechende Zwischenelemente oder Distanzstücke einzufügen, um - ausgehend von einem relativ schmalen Sitzrahmen 7 - jeweils stufenweise größere Breiten zu realisieren.The seat frame 7 is because it consists of the two seat frame halves 16 is assembled, its width is very simply variable. It is only necessary to do this Insert intermediate elements or spacers to - starting from a relatively narrow seat frame 7 - in stages to realize larger widths.

Der vordere Bereich des Sitzrahmens 7 trägt weiterhin Beinstützen 27 mit Trittplatten 28. Diese sind in üblicher Weise eingehängt, längenverstellbar und/oder seitlich verschwenkbar. Auch hierzu wird auf die aus dem Stand der Technik bekannten Konstruktionen verwiesen. The front area of the seat frame 7 continues to carry leg supports 27 with tread plates 28. These are in the usual way hooked in, adjustable in length and / or laterally pivotable. Here too, reference is made to those known from the prior art Constructions referenced.

Wie eine Zusammenschau der Fig. 4 und 6 zeigt, weist jeder der Seitenrahmen 4 und 5 jeweils ein Steckrohr 29 auf, in welches das hintere Steckrohr 9 einsteckbar ist. Die Figurenkonstruktion wird durch ein oberes Bogenrohr 31 sowie eine Strebe 32 entsprechend abgestützt, sodass sich die Lagerung 14 für die Hinterradschwinge 15 ergibt, welche an ihrem Endbereich eine Antikipprolle 18 trägt. Der gesamte Aufbau des Fahrwerkrahmens ist somit sehr stabil und robust und ist mittels weniger Schraubverbindungen, welche das vordere und das hintere Steckrohr 8 und 9 verbinden, lösbar. Somit lassen sich einzelne Komponenten, beispielsweise eine nicht dargestellte Batterie, welche auf den Unterrohren 13 steht, leicht aus- und einbauen. Der Elektro-Rollstuhl kann auch in sehr einfacher Weise an zusätzliche Anforderungen angepasst werden, es können zusätzliche Komponenten, Steuerungseinheiten oder Ähnliches, eingebaut oder demontiert werden.As a synopsis of FIGS. 4 and 6 shows, each has the side frames 4 and 5 each have a plug-in tube 29, in which the rear tube 9 can be inserted. The figure construction is through an upper arc tube 31 and a Brace 32 supported accordingly, so that the storage 14 for the rear swing arm 15, which on her End region carries an anti-tip roller 18. The whole structure the chassis frame is therefore very stable and robust by means of fewer screw connections, which the front and connect the rear tube 8 and 9, detachable. So leave individual components, for example one not shown battery, which stands on the lower tubes 13, easy to remove and install. The electric wheelchair can also be used very easily adapted to additional requirements additional components, control units or the like, installed or dismantled.

Wie ebenfalls aus den Figuren ersichtlich ist, weist jeder Seitenrahmen 4, 5 an seinem vorderen Endbereich ein Lagerrohr 30 auf, an welchem die bereits beschriebene Gabel 22 des Vorderrads 1 gelagert ist.As can also be seen from the figures, everyone points Side frame 4, 5 has a bearing tube at its front end region 30 on which the fork 22 already described the front wheel 1 is mounted.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, vielmehr ergeben sich im Rahmen der Erfindung vielfältige Abwandlungs- und Modifikationsmöglichkeiten. The invention is not based on the embodiment shown limited, rather arise within the scope of the invention diverse options for modification and modification.
