Definitions

  • the invention relates to a drive and Brake assist device for wheelchairs on the frame of a Wheelchair is attachable and at least one motorized powered and if necessary to the floor between the lower wheel of the wheelchair having.
  • the swivel lever practices one Force component on the drive wheel in the direction under the Center of gravity of the wheelchair.
  • the well-known Sliding devices are therefore not used as Brake aids suitable.
  • the drive and brake assist device characterized according to the invention, that the at least one drive wheel on a swivel arm, whose pivot point is roughly the same distance from the ground like the axis of rotation of the at least one drive wheel is arranged, is attached. With such an arrangement becomes a uniform contact pressure of the drive wheel both reached when going uphill or downhill.
  • the device can now also be used as a brake Downhill descents can be used.
  • a lifting motor to lower and raise the minimum a drive wheel may be provided. It can expediently the lifting motor via an intermediate Spring can be coupled to the at least one drive wheel.
  • the lift motor also makes it easier the commissioning and switching off of the auxiliary device. in the Contrary to conventional sliding devices, in which the usually two drive wheels by hand from one Locking mechanism must be released and lowered, The lifting motor takes over this work here.
  • the power supply to the motors the device can expediently have a battery respectively.
  • Fig. 1 shows a wheelchair 10 on the frame 11 a Pushing and braking device 12 with the help of Fig. 3 apparent fasteners 13 is arranged.
  • the Fastening device 12 consists of a drive wheel 14, that between the two wheels 15 and 16 of the wheelchair 10 is arranged.
  • the drive wheel 14 is on a swivel arm 17 stored, the pivot point D at the same distance from the ground 24 arranged as the axis 18 (Fig. 3) of the drive wheel 14 is.
  • the swivel arm 17 is connected to the axis 18 (Fig. 2) and has a boom 17.1 on which a spring 19 is articulated.
  • the other end of the spring 19 is one Spindle 20 connected by a lifting motor 21 in rotation is offset and thereby the articulation point 22 (Fig.
