Abstract

The wheelchair comprises a movement mechanism frame, a lift column and a seat unit. The lift column is foldable and suspendable on the movement mechanism frame. The seat unit is connected to the lift column, being height-adjustable, upwardly foldable and removable. The lift column comprises three aluminum square tubes fitted in one another by slide plates. In the outermost tube a high power motor with planet gear (1) is flanged onto the main bearing block (2). By means of a ball spindle (3) via a ball nut (4) in the innermost tube the column can be pushed upwards. The spindle back run is stoppable by a magnet brake (5) flanged onto the motor.

Description

Der erfindungsgemässe Rollstuhl, vorwiegend zum Gebrauch in Innenräumen, ist ein Hilfsmittel für behinderte und alte Personen.
Der grosse Verstellbereich der Sitzhöhe vom Boden bis auf 95 cm ermöglicht das Aufstehen und den Zugang zu oberen Gestellen und hilft somit, die Selbständigkeit zu verlängern.The wheelchair according to the invention, primarily for indoor use, is an aid for disabled and old people.
The large adjustment range of the seat height from the floor up to 95 cm enables you to stand up and access to upper frames, thus helping to extend your independence.

Die Bedürfnisse dieser Personengruppe erfordern darum den hier beschriebenen, speziellen Konstruktionsaufbau, der es erlaubt den Sitz zwischen den Seitenholmen ganz auf den Boden abzusenken.
Die Radnaben-Motoren mit dazwischen liegendem Batteriekoffer im hinteren Bereich ergeben einen sehr kompakten Aufbau mit optimalem Schwerpunkt und grosser Stabilität, auch bei der möglichen Sitzhöhe von 95 cm.
Die minimale Breite und Länge beträgt nur 58 x 85 cm, die Höhe bei eingefahrener Liftsäule nur 90 cm. Dies ergibt eine ansprechende und leicht wirkende Optik, speziell wichtig für den Wohnbereich.The needs of this group of people therefore require the special construction described here, which allows the seat between the side rails to be lowered completely onto the floor.
The wheel hub motors with the battery case in between in the rear area result in a very compact design with an optimal center of gravity and great stability, even with the possible seat height of 95 cm.
The minimum width and length is only 58 x 85 cm, the height when the lift column is retracted is only 90 cm. This results in an appealing and light-looking look, especially important for the living area.

Die Liftsäule für die Sitzverstellung besteht einerseits aus dem 3-fachen Teleskophub und der angebauten Nutschiene. Diese wiederum trägt das darin gleitende Sitzprofil mit der Rücklehne und dem hochklappbaren Sitz.
Die abklapp- und aushängbare Säule bezieht über den integrierten Stecker im Sockel und die Flexleiter im Innern die Stromversorgung für die beiden Motoren und die Regelelektronik.
Mittels Kugelbolzen können Liftsäule, Sitz- und Rückenelement ohne Werkzeug demontiert werden.
Ebenso sind die Antriebsräder und der Batteriekoffer für den leichten Transport einzeln steckbar.
Durch diese Bauweise, vorwiegend mit Staridard-Aluprofilen wird ein relativ leichtes und kostengünstiges Fahrzeug erreicht.The lift column for the seat adjustment consists on the one hand of the triple telescopic lift and the attached grooved rail. This in turn carries the sliding seat profile with the backrest and the fold-up seat.
The hinged and detachable column receives the power supply for the two motors and the control electronics via the integrated connector in the base and the flexible conductor inside.
Using the ball pin, the lift column, seat and back element can be removed without tools.
The drive wheels and the battery case can also be individually plugged in for easy transport.
This design, mainly with Staridard aluminum profiles, enables a relatively light and inexpensive vehicle to be achieved.
