Definitions

  • the present invention relates to a motor-driven Wheelchair equipped in particular for overcoming obstacles.
  • Such a wheelchair should be usable for indoor and outdoor use. With he can easily overcome obstacles up to 5 cm in height. The Overcoming obstacles up to 10 cm in height is possible, but one sets special driving technique ahead, which, however, many customers due to their Disability can not be assumed.
  • a particular aim of the invention is a drive concept which is cost-effective and is based on existing wheelchairs, in particular the "turbo-twist", assemble and disassemble. It has to be for the interior and Outdoor operation are suitable. Obstacles up to 10 cm high, should be possible without punches and can be overrun easily.
  • Figs 1-5 show schematically the operation of the Wheelchair.
  • the lower part of the wheelchair is in Fig. 6-8 laterally, in Fig. 9 and 10 obliquely, and shown in Fig. 11 seen from the rear.
  • the rearmost point of the wheelchair is the rear wheel bar so far. This rear wheel bar falls off the friction wheel drive. The diameters and the position of the additional and intermediate gears must be selected after this point.
  • gray tires with a pronounced profiling should be used come (gray tires are better for indoor use).
  • the auxiliary wheels must not be driven during normal driving nor allowed to drive Have contact with the ground.
  • the additional wheels may only be driven when with the wheelchair should be driven an obstacle.
  • the additional wheels and the intermediate wheels are sprung with a Bolted double swingarm.
  • the suspension of the swivel arms is called by Taken over Rosta elements.
  • the intermediate wheels are made with the help of eccentrics biased against the auxiliary wheels and are in constant engagement with these.
  • the goal is that the Doppelarmschwinge when driving over obstacles as early as possible and should deflect as little as possible, until the intermediate wheels have built up the full contact pressure against the drive wheels.
  • a stop for the double-arm swingarm must be attached to the base chassis, so that it can not deflect too far in the event of a possible puncture of the additional and drive wheels. Because the basic chassis for the Rosta elements, as they are used in the previous Heckradbügel, should also serve for the double-arm swingarm as a recording and fulcrum, the geometry of the positioning of the additional and intermediate wheels are given with little leeway.
  • the "turbo-twist" is in its original state from the rear wheel bar and a 140 mm swivel castor against tilting backwards.
  • the wheelchair thus has a very small turning circle.
  • the rear wheel arch and the castor are not required for the friction wheel drive.
  • V-belt or even separate electric motors drive the auxiliary wheels.
