Description
Die Erfindung betrifft einen Elektrorollstuhl mit einem Chassis, einem innerhalb des Chassis liegenden Schwerpunkt, am Chassis angeordneten Antriebsrädern und mindestens einem Lenkrad sowie mindestens einem im Chassis untergebrachten Akkumulator, der zur Einstellung der Lage des Schwerpunkts versetzbar ist.The invention relates to a power wheelchair with a chassis, a lying within the chassis center of gravity, arranged on the chassis drive wheels and at least one steering wheel and at least one housed in the chassis accumulator, which is displaceable for adjusting the position of the center of gravity.

Die optimale Schwerpunktposition wird durch die Anordnung der beiden zuletzt genannten Standardkomponenten eines Elektrorollstuhls im Zusammenspiel mit den Standardkörpermaßen eines Benutzers im Entwicklungsprozess des Rollstuhles durch Versuche oder Berechnungen festgelegt. Kommen nun spezielle Komponenten wie z. B. ein Hubsitz oder ein Aufrichtsitz hinzu, verändern diese die vorher berechnete optimale Schwerpunktposition. Ebenso verändern körperliche Gegebenheiten körperbehinderter Menschen, wie z. B. Beinamputierte oder Querschnittsgelähmte aufgrund der fehlenden bzw. kleineren Muskel- und Knochenmasse an den unteren Extremitäten den Schwerpunkt.The optimal center of gravity position is determined by the arrangement of the two last-mentioned standard components of an electric wheelchair in interaction with the standard body dimensions of a user in the development process of the wheelchair by experiments or calculations. Come now special components such. As a lifting seat or a Aufrichtsitz added, these change the previously calculated optimal center of gravity position. Likewise, changing physical conditions of physically disabled people, such. B. leg amputees or paraplegics due to the lack of or smaller muscle and bone mass at the lower extremities focus.
Hiervon ausgehend soll der eingangs beschriebene Rollstuhl dahingehend verbessert werden, dass der Veränderung des Schwerpunkts einfach und werkzeuglos erfolgen kann.On this basis, the wheelchair described above is to be improved to the effect that the change of the center of gravity can be done easily and without tools.
Zur Problemlösung zeichnet sich ein gattungsgemäßer Rollstuhl dadurch aus, dass die Lage des mindestens einen Akkumulators im Chassis mittels mindestens einer Sicherungsleiste fixierbar ist und dass das Chassis zwei gegenüberliegende Seitenwände umfasst, zwischen denen der mindestens eine Akkumulator aufgenommen ist, und die Seitenwände mindestens je zwei zueinander fluchtende Bohrungen aufweisen, und die Bohrungen zur Aufnahme von an den Enden der Sicherungsleiste angeordneten Rastbolzen vorgesehen sind, sodass die Lage des Schwerpunktes in Stufen einstellbar ist.To solve the problem, a generic wheelchair is characterized in that the position of the at least one accumulator in the chassis by means of at least one fuse strip is fixed and that the chassis comprises two opposite side walls, between which the at least one accumulator is received, and the side walls at least two each Have aligned holes, and the holes are provided for receiving disposed at the ends of the fuse strip locking bolts, so that the position of the center of gravity is adjustable in stages.
Durch diese Ausgestaltung kann der Schwerpunkt des Rollstuhles an die veränderte Schwerpunktlage, die sich beispielsweise durch vom Standardmaß abweichende körperliche Gegebenheiten des Benutzers einstellt, ausgeglichen werden. Da der Akkumulator eine hohe Masse besitzt, führen bereits kleinere Lageveränderungen zu einer deutlichen Verschiebung des Schwerpunktes. Die konstruktiv besonders einfache Lösung erfolgt durch die beiden gegenüberliegenden Seitenwände und die Bohrungen zur Aufnahme der von an den Enden der Sicherungsleiste angeordneten Rastbolzen.As a result of this configuration, the center of gravity of the wheelchair can be compensated for the changed center of gravity position, which is established, for example, by physical conditions of the user deviating from the standard dimension. Since the accumulator has a high mass, even minor changes in position lead to a significant shift of the center of gravity. The structurally particularly simple solution is provided by the two opposite side walls and the holes for receiving the arranged at the ends of the fuse strip locking pin.
Wenn einer der Rastbolzen gegen die Kraft einer Feder in die Sicherungsleiste einschiebbar ist, kann die Sicherungsleiste ohne Werkzeug aus dem Chassis herausgenommen werden, so dass der Akkumulator zu Wartungsarbeiten einfach zugänglich ist. Durch die zueinander fluchtenden Bohrungen werden jeweils Fixierungspunkte für die Sicherungsleiste geschaffen, gegen die der Akkumulator dann angelegt werden kann.If one of the locking bolts against the force of a spring in the fuse strip can be inserted, the fuse strip can be removed without tools from the chassis, so that the battery is easily accessible for maintenance. By aligned holes each fixing points are created for the fuse strip, against which the accumulator can then be created.
Um den Akkumulator im Chassis gegen unbeabsichtigtes Verschieben zu sichern, ist vorzugsweise beidseitig zu ihm je eine Sicherungsleiste vorgesehen. Die eine Sicherungsleiste ist vorzugsweise mit dem Chassis fest verschraubt, wodurch eine kostengünstige Sicherung erzielt wird. Insbesondere vorteilhaft ist es, wenn das Chassis eine mit den Seitenwänden verbundene Bodenplatte aufweist, mit der die Sicherungsleiste verschraubbar ist.In order to secure the accumulator in the chassis against unintentional displacement, a fuse strip is preferably provided on both sides of him. The one fuse strip is preferably firmly bolted to the chassis, whereby a cost-effective backup is achieved. It is particularly advantageous if the chassis has a base plate connected to the side walls, with which the fuse strip can be screwed.
