  • Pushing aids in wheelchairs serve to support a wheelchair pushing escort both on level, rising and falling Terrain.
  • a pushing aid is provided by the accompanying person operates and differs from so-called self-propelled vehicles operated by a wheelchair user.
  • the Pushing aid also for braking the wheelchair, which is particularly the case Slope matters.
  • One equipped with such a pushing aid Wheelchair is known from EP 0 592 427 B1.
  • the wheelchair described includes a drive unit as a pushing aid Is part of a swing arm, the axis of rotation of which is transverse to the direction of travel of the wheelchair.
  • the drive unit is at the rear End of the swing arm and consists essentially of an electrical Motor unit, accumulators, one gear and two in parallel mutually arranged drive wheels, whose axis of rotation parallel to Axis of rotation of the rear wheels of the wheelchair is arranged.
  • the ground contact the drive wheels are between the two larger ones Rear wheels of the wheelchair approximately on a connecting line between the ground contact points of the two main wheels. The necessary contact pressure the drive wheels on the floor result from the dead weight the drive unit.
  • the rocker carrying the drive unit comprises a longitudinally of the wheelchair extending pipe section, at the front end of a in Transverse linkage, first linkage carrying crossbar is arranged.
  • Can be moved in the longitudinal direction of the crossbar Thru axles arranged with which the swing arm with second, Lanyards arranged on the wheelchair can be connected.
  • the second connection means it is on each side of the wheelchair assigned receptacle into which such a thru-axle is inserted can be.
  • the thru axles are in the recordings according to yours Assembly rotatably arranged so that the arranged on the crossbar Swing around the axis of rotation of the thru axles in the vertical direction is pivotable.
  • the second connection means are on the subject EP 0 592 427 B1 in the area of the front swivel wheels of the wheelchair arranged so that a mounting of the rocker on the wheelchair is only possible from the front. If the pushing aid is to be installed, if a wheelchair user has taken a seat in the wheelchair, then the swing arm is attached by the legs of the wheelchair user through it.
  • Two belts are provided for lifting the drive unit, based on which the drive unit in its raised by operating a foot lever Position can be raised in which the drive wheels none Have more ground contact.
  • the invention lies on the basis of this discussed prior art therefore the task of a generic mentioned above To further develop a wheelchair in such a way that even on gradients permanent ground contact of the drive wheels of the drive unit guaranteed is.
  • This object is achieved in that as needed Increase the contact pressure on the drive wheel or wheels by a companion of the wheelchair has a push bar that in vertically swiveling about a lever arm in the area the axis of rotation of the rear end of the wheelchair is articulated, on which lever arm a push rod engages with its upper end, the lower end of which is articulated with the one carrying the drive unit Swing arm is connected.

  • On the lever arm on which the Push rod is articulated grips a push rod with its upper one End, the lower end of which is articulated with the one carrying the drive unit Swing arm is connected. Since the drive unit is part of the swing arm, can be provided that the push rod with its lower end also is articulated directly to the drive unit.
  • the push rod is one rigid grains can act by pushing down the push bar the contact pressure of the drive wheels on the ground can be increased.
  • a contact pressure can be easily achieved, especially on downhill gradients, in which the drive wheels are left in constant contact with the ground and thus enables wheelchair braking by the drive unit itself is. If there is no downward pressure on the push rod exercised by the accompanying person, the dead weight acts on the drive wheels the drive unit, this additionally by the weight of the push rod and the push rod over that of the prior art State of the art is increased.
  • the vertical Push bar pivotable upwards over a dead center is pivotable and in this position over the dead center acts against a stop.
  • the Drive unit by swiveling the push rod up from the floor be raised.
  • the push rod in on the push handles Wheelchair arranged push handle extensions held what a easy assembly of the push bar on the wheelchair and also one problem-free retrofitting of an existing wheelchair allowed.
  • a swing arm with the drive unit elastic section, at the rear end of the drive unit and the front end of which arranged the first connecting means of the rocker are to be connected to the frame of the wheelchair.
  • Such an elastic Section can, for example, by using a rubber buffer be realized.
  • the advantage of such a realization of the swing arm is on the one hand that between the first connecting means and the second, fixed to the wheelchair connecting means Connection can be provided. It is advantageous in such an arrangement but also that the drive unit not only in the vertical direction, but can also be pivoted in other directions, which relates to the Drive behavior of the drive wheels, especially on uneven terrain advantageous noticeable.
  • the axis of rotation of the drive wheels can namely run inclined to the axis of rotation of the main wheels, so that when driving through potholes both drive wheels in contact with the ground remain.
  • the pushing aid To mount the pushing aid on the wheelchair, it can be provided that as the first connection means two each assigned to a wheelchair side, to provide recordings defined by tabs, through which two Tabs a locking bolt is arranged reaching through. Connecting tongues attached to the wheelchair are the second connecting means provided that also a corresponding opening exhibit.
  • the pushing aid is thus attached to the wheelchair can be brought about in that the receptacle is arranged on the wheelchair Connection tongue is brought and then the locking bolt for reaching through the tabs and the connecting tongue be operated.
  • the locking bolts are expedient for this purpose coupled to a Bowden cable that consists of one for the accompanying person comfortable position can be operated.
  • the pushing aid with the first connecting means to the second connecting means can be provided that each side of the vehicle a corresponding guide rail is assigned, on which the first connection means placed and in this attached position can be fed to the second connecting means.
  • a wheelchair 1 is equipped with a pushing aid 2.
  • the one in the figures shown only schematically by mapping the right side of the wheelchair Wheelchair 1 comprises a frame 3, at the front end on the underside Swivel wheels 4 are articulated.
  • In the area of the rear end of the Wheelchairs 1 are two large rear wheels 5, of which in the Figures only the right rear wheel 5 is shown.
  • the frame 3 of the Wheelchair 1 comprises two parallel to each other at its rear upper end push handles 6 pointing in the direction of travel, at the ends of each a push handle extension 7 is arranged.
  • the pushing aid 2 of the wheelchair 1 consists essentially of one Drive unit 8 comprising an electric motor 9, two accumulators 10, 10 'a gear 11 and two drive wheels arranged parallel to one another 12, of which the left in the direction of travel is shown in the figures is.
  • the axis of rotation of the drive wheels 12 is basically parallel to Axis of rotation of the rear wheels 5 arranged.
  • the drive unit 8 is over two rubber blocks 13 running parallel to each other in the direction of travel first connecting means 14 connected.
