Description

Die Erfindung betrifft einen von einer Energiequelle versorgter Antriebsmotor filr scheibenförmige oder radförmige Körper mit einer Steuervorrichtung.The invention relates to a drive motor supplied with an energy source for disk-shaped or wheel-shaped bodies with a control device.

Aufgabe der Erfindung ist es eine Antriebseinheit für rad- oder scheibenförmige Körper, bspw. bei RollstUhlen, Fahrräder u.dgl., die aus einer Energiequelle mit einem Antriebsmotor, der gegebenenfalls ein Getriebe bzw. Teile eines Getriebes aufweist, besteht, so auszubilden, daß sie sich aus einigen miteinander bspw. durch Leitungen verbundenen Teilen von geringem Gewicht und Baugröße zusammensetzt, so daß nie vor allem für schwächliche, kränkliche und/ oder körperbehinderte Personen auch einhändig in beliebiger Art bedienbar ist, ohne daß dadurch eine Minderung in der Funktion und Leistung entsteht.The object of the invention is to provide a drive unit for wheel-shaped or disc-shaped bodies, for example in wheelchairs, bicycles and the like, which consists of an energy source with a drive motor, which may have a transmission or parts of a transmission, in such a way that it is composed of some parts of low weight and size, for example connected by cables, so that it can never be operated with one hand in any manner, especially for weak, sickly and / or physically handicapped people, without a reduction in function and performance arises.

Die Erfindung löst diese Aufgabe dadurch, daß der Antriebsmotor mit dem scheibenförmigen oder radförmigen Körper gegebenenfalls über ein Getriebe in Wirkverbindung bringbar und in dieser in einer Ruhelage leicht löslich fixierbar ist.The invention solves this problem in that the drive motor with the disk-shaped or wheel-shaped body can optionally be brought into operative connection via a gear and can be easily detachably fixed in a rest position.

Eine weitere Ausßentaltung der Erfindung ist es, daß der Antriebsmotor an das Getriebe, das mit dem rad- oder scheibenförmigen Körper in ständiger Verbindung ist, ansteckbar ist, aber auch, daß der Antriebsmotor mit dem Getriebe als Einheit an den rad- oder scheibenförmigen Körper ansteckbar ist, oder daß der Antriebsmotor mit einem Teil des Getriebes mit dem restlichen Getriebeteil der am rad- oder scheibenförmigen Körper angeordnet ist, in Wirkverbindung bringbar ist.A further external design of the invention is that the drive motor can be plugged onto the gear, which is in constant connection with the wheel or disk-shaped body, but also that the drive motor can be plugged into the wheel or disk-shaped body as a unit is, or that the drive motor can be brought into operative connection with a part of the transmission with the rest of the transmission part which is arranged on the wheel-shaped or disc-shaped body.

Weiters ist es erfindungsgemäß möglich, daß der Antriebsmotor direkt an den rad- oder scheibenförmigen Körper ansteckbar ist, daß der Antriebsmotor ein Elektromotor ist, daß die Energiequelle eine Batterie ist, die aus einzelnen im mechanischem Aufbau getrennt gehaltenen Batterieelementen besteht, und daß die Batterieelemente untereinander mittels Leitungen und/ode Steckverbindungen verbunden und mit einer gemeinsamen Handhabe bedienbar sind.Furthermore, it is possible according to the invention that the drive motor can be plugged directly onto the wheel-shaped or disk-shaped body, that the drive motor is an electric motor, that the energy source is a battery, which consists of individual battery elements which are kept separately in the mechanical structure, and that the battery elements are mutually connected are connected by means of lines and / or plug connections and can be operated with a common handle.

Eine andere erfindungsgemüße Möglichkeit ist dadurch gegeben, daß die Energiequelle ein Kleingenerator ist, oder daß der Antriebsmotor ein Kraftstoffmotor ist.Another possibility according to the invention is given in that the energy source is a small generator or in that the drive motor is a fuel motor.

Erfindungsgemäß ist es ferner möglich, daß das Getriebe ein an sich bekanntes Getriebe wie beispielsweise ein Zahnradgetriebe, ein Reibradgetriebe, ein Riemen-oder Kettengetriebe, ein Gelenkgetriebe oder ein hydraulisches Getriebe ist.According to the invention, it is also possible for the transmission to be a transmission known per se, such as a gear transmission, a friction gear transmission, a belt or chain transmission, an articulated transmission or a hydraulic transmission.

Beim hydraulischen Getriebe kann beispielsweise der Antriebsmotor mit einer Pumpeneinheit an einem vom Rad entfernten Teil angeordnet sein, wobei das Turbinenrad mit der Felge fest verbunden ist. Die Zuführung beispielsweise von Öl erfolgt dann über Schläuche mit Schnellkupplungen, die beim Abziehen gleichzeitig dichtend abschließen, so daß kein Ölverlust entsteht.In the hydraulic transmission, for example, the drive motor with a pump unit can be arranged on a part remote from the wheel, the turbine wheel being firmly connected to the rim. Oil, for example, is then supplied via hoses with quick-release couplings, which at the same time seal when pulled off, so that there is no loss of oil.

Eine weitere Möglichkeit bietet sich durch einen Kleingenerator, der mit Batterieelementen verbunden ist, die wiederum an einem beispielsweise zentral und direkt in die Felge eingesteckten und durch Spannverschlüsse fixierten Scheibenmotor ihre vom Generator ständig ergänzte Engergie angeben.A further possibility is provided by a small generator which is connected to battery elements which, in turn, indicate their energy, which is constantly supplemented by the generator, on a disc motor which is, for example, inserted centrally and directly into the rim and fixed by means of tension locks.

Durch die leichte Handhabung der voneinander getrennt angeordneten Antriebselemente die mittels Kabel und/oder Steckverbindungen bei Kraftstoffmotoren auch über Seilzüge und Kraftstoffleitungen miteinander verbunden sind, ist es einer einzelnen Person die z. B. behindert und auf einem Rollstuhl angewiesen ist, leicht möglich, mit ein paar einfachen Handgriffen aus einem normalen Faltrollstuhl einen elektrisch angetriebenen Rollstuhl zu machen. Dies ist vor allem bei älteren Rollstuhlbenutzern, die als weiteres Transportmittel noch zusätzlich ein Auto benützen, von großem Vorteil, da sie von Begleitpersonen größtenteils unabhängig werden.Due to the easy handling of the separately arranged drive elements which are connected to one another by means of cables and / or plug-in connections in fuel engines via cable pulls and fuel lines, it is a single person who, for. B. is disabled and dependent on a wheelchair, easily possible to make an electrically powered wheelchair with a few simple steps from a normal folding wheelchair. This is of great advantage especially for older wheelchair users who also use a car as an additional means of transport, as they are largely independent of accompanying persons.

Der erfindungsgemäße Rollstuhl ist also ein Faltrollstuhl, an dem mit ein paar Handgriffen eine elektrische Antriebseinheit und die dazugehörige Batterie oder ein Kleingenerator montiert, also z. B. angesteckt werden kann. Es wird somit aus einem Faltrollstuhl mit seinen Vorteilen ein Elektrorollstuhl mit seinen Vorteilen.The wheelchair according to the invention is thus a folding wheelchair on which an electric drive unit and the associated battery or a small generator can be mounted in a few simple steps. B. can be infected. It turns a folding wheelchair with its advantages into an electric wheelchair with its advantages.

Die Antriebseinheit besteht aus einem bzw. zwei Motoren, die an das bzw. die Räder montiert also z. B. angesteckt werden, sowie aus den Batteriekästen mit der Steuerung die z. B. an die vorderen Enden der Armlehnen montiert bzw. angesteckt werden. Bei Verwendung von einem einzigen Motor ist eine Lenkung vorzusehen. Die Teile der Antriebseinheit sind gewichtsmäßig so ausgelegt, daß sie vom Behinderten im Rollstuhl sitzend bzw. von einer Begleitperson leicht montiert, also z. B. angesteckt oder abgenommen werden können. Durch diese Umbaumöglichkeit werden die Nachteile des Elektrorollstuhls, daß er nicht faltbar ist und deshalb sowie aufgrund seines hohen Gewichts schlecht und schon gar nicht vom Behinderten in ein Auto oder in ein anderes Verkehrsmittel geladen werden kann, aufgehoben. Ein Behinderter kann also mit dem erfindungsgemäßen Rollstuhl elektrisch zu seinem Auto fahren, die Antriebseinheit abnehmen, in den Kofferraum verladen und dann wie mit einem normalen Faltrollstuhl einsteigen.The drive unit consists of one or two motors, which are mounted on the wheel or wheels, e.g. B. be plugged in, and from the battery boxes with the control z. B. be attached to the front ends of the armrests. Steering must be provided when using a single motor. The parts of the drive unit are designed in terms of weight so that they sit easily in a wheelchair by the disabled or easily assembled by an accompanying person, e.g. B. can be infected or removed. This conversion option eliminates the disadvantages of the electric wheelchair that it is not foldable and therefore, and because of its high weight, difficult and certainly not loadable by the disabled in a car or other means of transport. A disabled person can therefore drive the wheelchair according to the invention electrically to his car, remove the drive unit, load it into the trunk and then get in like with a normal folding wheelchair.

Die Batterien können im Auto so untergebracht werden, daß sie vom Generator während der Fahrt wieder aufgeladen werden.The batteries can be placed in the car so that they can be recharged by the generator while driving.

Der erfindungsgemäße Rollstuhl kann in der Wohnung wie ein normaler Rollstuhl benützt werden, beim Ausfahren braucht der Rollstuhl nicht gewechselt werden, es wird lediglich die Antriebseinheit montiert bzw. angesteckt und der Rollstuhlbenützer kann sich mittels Elektroantrieb fortbewegen. Es ist dadurch keine Abstellfläche für einen zweiten Rollstuhl notwendig. Der e'rfindungsgem-äße Rollstuhl ermöglicht es einem Teil von Behinderten, erstmals sich ohne Begleitperson mit dem Auto oder anderen Verkehrsmitteln fortzubewegen. Außerdem ist die Einsatzmöglichkeit des erfindungsgemäßen Rollstuhls gegenüber bisherigen RollstUhlen durch die Möglichkeit, ihn mit dem Auto leicht transportieren zu können, auf einen größeren Personenkreis erweitert.The wheelchair according to the invention can be used in the apartment like a normal wheelchair, the wheelchair does not need to be changed when it is extended, only the drive unit is mounted or plugged in and the wheelchair user can move by means of an electric drive. This means that there is no need for a second wheelchair. The wheelchair according to the invention enables some of the disabled to travel by car or other means of transport for the first time without an accompanying person. In addition, the use of the wheelchair according to the invention compared to previous wheelchairs is by expanded the possibility of being able to easily transport it by car to a larger group of people.

Außerdem ist es möglich, mit der erfindungsgemäßen Antriebsvorrichtung auch Fahrräder, Kinderwagen, Handkarren aber auch beispielsweise mit dem Reibradbetriebe Töpferscheiben, Schleifscheiben und dergleichen anzutreiben.In addition, it is possible to drive bicycles, prams, hand carts with the drive device according to the invention, but also, for example, with the friction wheel operation, pottery wheels, grinding wheels and the like.

Die Erfindung wird in der Zeichnung anhand eines AusfUhrungsbeispieles näher erläutert.The invention is explained in more detail in the drawing using an exemplary embodiment.

Es zeigen Figur 1 in einer Seitenansicht die erfindungsgemäße Antriebseinheit als Antrieb eines faltbaren Rollstuhls, der in Figur 2 in der Draufsicht, dargestellt ist. Die Figur 3 zeigt die erfindungsgemäße Antriebseinheit an einem Zugteil für Rollstühle in einer Seitenansicht, Figur 4 -zeigt die erfindungsgemäße Antriebseinheit, losgelöst von einem anzutreibenden Mittel. In der Figur 5 ist ein in einem Rad integriertes Getriebe, auf das der Motor aufgesteckt und fixiert wird, in einem Schnittbild dargestellt, wobei die Figur 6 ebenfalls in einem Schnittbild eine andere Variante zeigt. Die Figur 7 zeigt als Antriebsmittel eine Variante eines Reibradgetriebes. Die Figuren 8a bis 8f veranschaulichen den Gebrauch eines erfindungsgemäß ausgeführten Rollstuhls. durch einen behinderten Autofahrer.FIG. 1 shows a side view of the drive unit according to the invention as the drive of a foldable wheelchair, which is shown in a top view in FIG. 2. FIG. 3 shows the drive unit according to the invention on a pulling part for wheelchairs in a side view, FIG. 4 shows the drive unit according to the invention, detached from a means to be driven. FIG. 5 shows a transmission integrated in a wheel, onto which the motor is plugged and fixed, in a sectional view, FIG. 6 also showing another variant in a sectional view. FIG. 7 shows a variant of a friction wheel transmission as the drive means. Figures 8a to 8f illustrate the use of a wheelchair designed according to the invention. by a disabled driver.

Aus der Zeichnung ist zu ersehen, daß die erfindungsgemäße Antriebsvorrichtung 1 aus dem Batterieelemententräger 2 mit einer Steuervorrichtung 3 und der dazugehörigen Handhabe 4 besteht. Der Batterieträger 2 ist mit den Haken 5, 6 in diverse Aufnahmeschlitze beispielsweise an einem Fahrrad, Rollstuhl oder dergleichen einhängbar. Über das Kabel 7, 8, das durch eine Kupplung teilbar ist, ist er mit einem Motor 11 verbunden (Figur 4). Der Motor 11, der mit einem Handgriff 9 versehen ist, wird an eine mit einem Zapfen versehene Welle 14, das in der Felge des anzutreibenden Rades 12 angeordneten Getriebes 13 angesteckt, und mit einem Drehverschluß 15 an dem am Getriebegehäuse 16 befindlichen Gewindegang 17 fixiert (Figur 5). Eine weitere Möglichkeit ergibt sich dadurch, daß das Getriebe 18 mit dem Motor 11 eine bauliche Einheit bildet, die auf eine Welle 19 aufgeschoben und durch Verdrehen in die Fahrtrichtung am Lagerteil 20 fixiert wird (Figur 6). Der Motor 11 und das Getriebe 18 können dabei als sogenannter Scheibenmotor ausgebildet sein, d. h. als scheibenförmiger, in die Nabe des Rades 12 einbaubarer Motor.From the drawing it can be seen that the drive device 1 according to the invention consists of the battery element carrier 2 with a control device 3 and the associated handle 4. The battery holder 2 can be hooked with the hooks 5, 6 into various receiving slots, for example on a bicycle, wheelchair or the like. It is connected to a motor 11 via the cable 7, 8, which can be divided by a coupling (FIG. 4). The motor 11, which is provided with a handle 9, is connected to a shaft 14 provided with a pin, the gear 13 arranged in the rim of the wheel 12 to be driven is plugged in and fixed with a rotary lock 15 to the thread 17 on the gear housing 16 (FIG. 5). Another possibility results from the fact that the gear 18 forms a structural unit with the motor 11, which is pushed onto a shaft 19 and fixed to the bearing part 20 by turning in the direction of travel (FIG. 6). The motor 11 and the transmission 18 can be designed as a so-called disk motor, ie as a disk-shaped motor that can be installed in the hub of the wheel 12.

Weiters kann der Antrieb eines Rades 21 auch dadurch erfolgen, daß der Motor 11 mit einem Reibradgetriebe 22 ausgerüstet ist, wobei das Antriebsrad. 23 mit dem federbelasteten Gegenrad 24 über das Rad 21 geschoben wird und der Motor 11 beispielsweise bei einem Fahrrad an dessen Gabel mittels nicht gezeigter Klemmverschlüsse fixiert wird, wobei die Batterieelemente 2 und 2' auf dem Gepäckträger und die Steuervorrichtung 3, 4 auf die Lenkstange montiert werden (Figur 7).Furthermore, the drive of a wheel 21 can also take place in that the motor 11 is equipped with a friction gear 22, the drive wheel. 23 with the spring-loaded counter wheel 24 is pushed over the wheel 21 and the motor 11 is fixed, for example in the case of a bicycle, to its fork by means of clamp closures (not shown), the battery elements 2 and 2 'being mounted on the luggage rack and the control device 3, 4 on the handlebar be (Figure 7).

Bei FaltrollstUhlen 30 werden die Batterieelemente 2, 2' mit dem Steuerteil 3, 4 beispielsweise an den Vorderseiten der Armlehnen 25, 26 angesteckt, wobei die Kabel 7, 8, 27, die die Batterieelemente 2, 2' miteinander und mit den Motoren 11, 11' verbinden, mittels Kabelklemmen 28, 28', 29, 29', 27, 27', an das Rohrprofil der Armlehnen 25, 26 befestigt sind (Figur 1 und 2).In the case of folding wheelchairs 30, the battery elements 2, 2 'are connected to the control part 3, 4, for example on the front sides of the armrests 25, 26, the cables 7, 8, 27 which connect the battery elements 2, 2' to one another and to the motors 11, 11 'connect, by means of cable clamps 28, 28', 29, 29 ', 27, 27', attached to the tubular profile of the armrests 25, 26 (Figures 1 and 2).

Wie in Figur 8a bis 8f dargestellt ist, kann mit einem erfindungsgemäßen Rollstuhl 30 eine behinderte Person 40 zu einem Auto fahren (Figur 8a), dort den aufsteckbaren Motor 11 abnehmen (Ftgur 8b) und ihn in den Kofferraum 42 des Autos 41 verladen (Figur 8c).
