Die Erfindung betrifft einen Rollstuhl, insbesondere einen Rollstuhl mit einer zusätzlichen Hilfsantriebseinrichtung . The invention relates to a wheelchair, in particular a wheelchair with an additional auxiliary drive device.
Ein herkömmlicher Rollstuhl umfasst einen Stuhlrahmen mit einer Sitzfläche zwischen zwei grossen Antriebsrädern sowie zwei kleinere Hilfsräder und Fussstützen vor diesen. Die Antriebsräder sind auf ihrer Aussenseite mit einem A conventional wheelchair includes a chair frame with a seat between two large drive wheels and two smaller auxiliary wheels and footrests in front of them. The drive wheels are on the outside with a
Antriebsring versehen, der wiederum mit der Radfelge Drive ring provided, in turn, with the wheel rim
verbunden ist. Die Antriebsringe sind mit den Händen drehbar, was eine eigenständige Fortbewegung ohne Drittpersonen ermöglicht . connected is. The drive rings are rotatable with the hands, which allows independent movement without third parties.
Da diese Fortbewegung kraftaufwändig ist, wurde in der DE-U- 202010005729 ein Antrieb vorgeschlagen, der eine  Since this locomotion is power consuming, a drive was proposed in DE-U-202010005729, the one
kraftsparende und sichere Handhabung ermöglichen soll. Dies erfolgt durch einen Antriebshebel, der an den Radachsen der Antriebsräder angelenkt ist und um die Radachse hin- und hergeschwenkt werden kann. Die Antriebshebel reichen über den Radius des Antriebsrades hinaus und sind mit einem Handgriff und einer Bremse versehen. Die Schwenkbewegung eines to enable energy-saving and safe handling. This is done by a drive lever which is articulated on the wheel axles of the drive wheels and can be pivoted back and forth about the wheel axle. The drive levers extend beyond the radius of the drive wheel and are provided with a handle and a brake. The pivoting movement of a
Antriebshebels ist durch einen, in einem Längsschlitz eines Schutzblechs geführten Verlängerungsarm begrenzt. Drive lever is limited by a guided in a longitudinal slot of a mudguard extension arm.

Bei einer ähnlichen Lösung gemäss DE-U-202007008736 ist jedes Antriebsrad Teil eines Antriebsradmoduls mit einem im Gestellrahmen des Rollstuhls angeordneten Antriebsaggregats um die Breite des Rollstuhls gering zu halten. In a similar solution according to DE-U-202007008736, each drive wheel is part of a drive wheel module with an im Frame frame of the wheelchair arranged drive unit to keep the width of the wheelchair low.
Die im Rollstuhl sitzende Person muss zur Fortbewegung mindestens eine Hand einsetzen um einen Antriebsring eines Antriebsrades zu drehen und/oder die Steuereinrichtung eines Antriebsaggregats zu bedienen. The person sitting in the wheelchair must use at least one hand to move around a drive ring of a drive wheel and / or to operate the control device of a drive unit.
Der Erfindung liegt somit die Aufgabe zugrunde, die The invention is therefore the object of the
geschilderten Nachteile des Standes der Technik zu meiden und einen Rollstuhl, insbesondere einen Rollstuhl mit einer zusätzlichen Hilfsantriebseinrichtung vorzuschlagen, der auch eine Bewegung des Rollstuhls ohne Einsatz der Hände described disadvantages of the prior art and to propose a wheelchair, in particular a wheelchair with an additional auxiliary drive device, which also allows movement of the wheelchair without the use of hands

Weitere bevorzugte Aus führungsformen sind in den abhängigen Ansprüchen offenbart. So kann die Radwelle als Kurbelwelle ausgebildet sein, deren Ausbiegungen zwecks Vermeidung von Totpunkten bevorzugt schräg oder gekrümmt ausgeformt sind oder sie beinhaltet eine Hebel-Stösselanordnung . Further preferred embodiments are disclosed in the dependent claims. Thus, the wheel shaft may be formed as a crankshaft whose bends in order to avoid Dead points are preferably formed obliquely or curved or it includes a lever-plunger assembly.
Jedes Antriebsrad verfügt über einen üblichen Antriebsring und/oder über einen Antriebshebel. Each drive wheel has a common drive ring and / or a drive lever.
Bei Einsatz von Zahnstangen-/Zahnradantrieben ist die When using rack / gear drives is the
Radwelle gerade, die Hebel sind als Zahnstangen ausgebildet und auf der Radwelle können sogar auf jeder Seite abgestufte Zahnräder nebeneinander angeordnet werden, so dass sich eine Gangschaltung ergibt. Ebenso könnte die Sitzunterseite als Zahnradsegment ausgebildet sein, das mit einer waagerecht angeordneten Zahnstange korrespondieren, deren Enden wiederum mit Hebeln oder Zahnstangen verbunden sind.  Wheel shaft straight, the levers are designed as racks and on the wheel shaft even graded gears can be arranged side by side on each side, so that there is a gearshift. Likewise, the seat bottom could be formed as a gear segment, which correspond to a horizontally arranged rack, the ends of which are in turn connected to levers or racks.
Mittels der Erfindung kann ein Rollstuhl allein durch eine Kippbewegung des Sitzes quer zur Fahrtrichtung bewegt werden, so dass die Hände z. B. für ein Ballspiel oder eine andere Betätigung frei bleiben, resp. gar handikapierte Hände kein Problem darstellen. Ein solcher Rollstuhl ist aber auch zum rückwärts fahren geeignet. Die Beweglichkeit des  By means of the invention, a wheelchair alone by a tilting movement of the seat are moved transversely to the direction of travel, so that the hands z. B. remain free for a ball game or another operation, resp. even handicapped hands do not pose a problem. Such a wheelchair is also suitable for driving backwards. The mobility of the
Rollstuhlfahrers wird damit erheblich erweitert. Wheelchair users will be significantly expanded.
Derartige Hebelgelenke oder Kurbelschwingen sind an sich von Handhebeldraisinen oder Holländern bekannt. In der DE-A- 3201310 ist zum Beispiel eine Antriebseinrichtung für Such lever joints or rocker arms are known per se from Handhebeldraisinen or Dutch. In DE-A-3201310, for example, a drive device for

Bicycles with lever joints described. On both sides of the bicycle such a drive device is mounted to avoid a dead center when pedaling.
In jedem Fall erfolgt die Betätigung der Hebelgelenke oder Kurbelschwingen ausschliesslich durch Hand- oder In any case, the operation of the lever joints or rocker arms is done exclusively by hand or
Beinbewegungen . Alternativ oder ergänzend sind auch diverse Antriebe denkbar, z. B. Elektroantriebe. Leg movements. Alternatively or additionally, various drives are conceivable, for. B. electric drives.
Es ist möglich, den erf indungsgemäss kippfähigen Sitz und Antrieb auch auf Fahrräder zu übertragen. Hierbei würde durch Kippbewegungen des Sitzes ein zusätzlicher, auf das Hinterrad wirkender Antrieb geschaffen, unter Beibehaltung des Pedal- und Kettenantriebs.  It is possible to transfer the seat and drive tiltable according to the invention to bicycles. This would be created by tilting movements of the seat, an additional, acting on the rear wheel drive, while maintaining the pedal and chain drive.
