Description

Für Rollstuhlfahrer, deren Körperkraft ausreicht, um sich selbstfahrend fortzubewegen, werden Rollstühle mit Handlaufreifen hergestellt.For wheelchair users whose physical strength is sufficient to wheelchairs become self-propelled made with handrail tires.

Handlaufreifen sind ringförmige Rohre, die seitlich an den Antriebsrädern befestigt werden. Bei dieser Antriebsmethode greift man den Reifen, bewegt ihn ein Stück kreiswärts, läßt ihn los und führt die Hand zurück, um den ganzen Bewegungsablauf zu wiederholen. Nachteile dieser Methode: Bei dem Zurückführen der Hände (teilweise Kreisbewegung mit Wiederansetzen) wird Kraft "nutzlos" verbraucht. Dies setzt den Wirkungsgrad dieser Antriebsmethode herab. Gleichzeitig werden die Hände durch ständiges Öffnen und Schließen belastet.Handrail tires are ring-shaped tubes that run sideways be attached to the drive wheels. At this Drive method you grab the tire, move it Circularly, let go and lead the hand back to repeat the whole sequence of movements. Disadvantages of this method: When returning the Hands (partially circular motion with reattachment) power is used "useless". This sets the Efficiency of this drive method. At the same time, the hands are opened constantly and closing loads.

Die der Anmeldung zugrunde­ liegende Aufgabe besteht darin, den Wirkungsgrad der zur Bewegung eingesetzten Kraft zu erhöhen und die Hände zu entlasten.The basis of the registration lying task is the efficiency of the force used to move and the Relieve hands.

Diese Aufgabe wird gelöst durch einen manuellen Rollstuhlantrieb gemäß dem Anspruch (1). Der beanspruchte Rollstuhlantrieb besteht aus zwei Komponenten:
einem Metallblech (2) und einem kugelgelagerten Haftmagnethaltegriff (4). Das Metallblech (2) muß magnetisch und möglichst rostfrei sein (z. B. Chromstahl 18/10). Je ein Metallblech (2) wird kreisförmig an die Antriebsräder (1) angepaßt und fixiert. This object is achieved by a manual wheelchair drive according to claim (1). The claimed wheelchair drive consists of two components:
a metal sheet ( 2 ) and a ball-bearing magnetic holding handle ( 4 ). The metal sheet (2) must be magnetic and corrosion-resistant as possible (eg. As chromium steel 18/10). One sheet of metal ( 2 ) each is circularly adapted and fixed to the drive wheels ( 1 ).

Der Haftmagnethaltegriff (4) besteht aus einem starken Haftmagneten und einem kugelgelagerten Griff, der die Kreisbewegung unterstützt und ein ständiges Öffnen und Schließen der Hände erübrigt.The holding magnet handle ( 4 ) consists of a strong holding magnet and a ball-bearing handle that supports the circular movement and eliminates the need for constant opening and closing of the hands.

Die magnetischen Haftkräfte, abhängig von Blechstärke und Leistung des Magneten, sollten so groß sein, daß ein Verschieben des Magneten auf dem Blech durch eine ruckartige Bewegung gerade noch möglich ist.The magnetic adhesive forces, depending on the sheet thickness and power of the magnet should be so large that moving the magnet on the sheet by a jerky movement is just still possible.

Der Magnetgriff (4) wird auf das am Antriebsrad (1) befestigte Blech (2) aufgesetzt und kreisförmig um die Radachse bewegt. Hierbei haftet der Magnet auf dem Blech und bewegt so das Rad mit. Ein ruckartiges Verschieben des Magneten zur Radachse hin ergibt eine andere Übersetzung (das System wirkt wie ein stufenloses Getriebe).The magnetic handle ( 4 ) is placed on the plate ( 2 ) attached to the drive wheel ( 1 ) and moved in a circle around the wheel axis. The magnet sticks to the sheet and moves the wheel with it. A jerky movement of the magnet towards the wheel axis results in a different ratio (the system acts like a continuously variable transmission).

Durch die Möglichkeit der kompletten Kreisbewegung wird ein permanenter flüssiger Bewegungsablauf erreicht und dadurch der Wirkungsgrad der zur Fortbewegung eingesetzten Kraft erhöht.Due to the possibility of complete circular movement becomes a permanent fluid movement achieved and thereby the efficiency of the Locomotive force increased.

Durch eine Kugellagerung des Haftmagnethaltegriffes ist ein ständiges Öffnen und Schließen der Hände überflüssig und entlastet so dieselben.Through a ball bearing of the magnetic handle is a constant opening and closing of the hands superfluous and thus relieves the same.

Claims (2)

1. Manueller Rollstuhlantrieb über die Antriebsräder, dadurch gekennzeichnet, daß jeweils ein kugelgelagerter Haftmagnethaltegriff auf ein an den Antriebsrädern befestigtes Metallblech aufgesetzt ist, wobei die Haftmagnethaltegriffe bei einer ruckfreien kreisförmigen Bewegung derselben zum Bewegen der Antriebsräder dienen.1. Manual wheelchair drive via the drive wheels, characterized in that in each case a ball-bearing holding magnet handle is placed on a metal sheet fastened to the driving wheels, the holding magnet handles serving to move the drive wheels with a jerk-free circular movement. 2. Manueller Rollstuhlantrieb nach Anspruch 1, dadurch gekennzeichnet, daß zum beliebigen stufenlosen Verändern des Übersetzungsverhältnisses die Haftmagnethaltegriffe mittels einer Ruckbewegung zur Radachse hin bzw. von der Radachse weg bewegbar sind.2. Manual wheelchair drive according to claim 1, characterized, that for any stepless change of Gear ratio the holding magnet handles by means of a jerk to the wheel axis or from the wheel axle are movable away.
