<p>The apparatus is for the simultaneous rotation and linear displacement with use of an actuator and a double, counterposed rotary spindle, preferably for a wheelchair or similar. The apparatus involves simultaneous rotation and radial translation, which has a main component (23), preferably with a double counterposed rotary spindle, which causes the actuator (5) to rotate. On the spindle are protective nuts, which can move either towards each other or away from one another, dependent upon the rotation of the spindle. A protective nut is in connection with a displacement component, which is thus moved linearly along the spindle, whilst another protective nut movement relatively to a rocker component results in the rotation of the main component.</p> |
