Definitions

  • the invention relates to a drive and brake assist device for wheelchairs, which can be fastened to the frame of a wheelchair is.
  • auxiliary devices facilitate pushing a person sitting in a wheelchair on slopes or on rough, difficult ground.
  • the pushing aids is also a support of braking at downhill Terrain possible.
  • the known sliding and braking aids have either a bepressbares to the ground and motor driven friction wheel or a hub drive for the wheels of the wheelchair.
  • the auxiliary devices With friction wheels have the disadvantage that the friction wheel with a relatively large contact pressure on the ground rest must be enough to be effective.
  • Hub drives are structurally complex and have an unfavorable transmission ratio, so usually a gear is required.
  • GB 2 043 554 A there is a drive device for wheelchairs known.
  • the power is transmitted to the wheels via an internal ring gear, either as a separate Part can be made and attached to the wheels or which may be formed on the inner surface of the wheels.
  • the inner ring gear may consist of a plurality of segments, which are attached to the inner surface of the wheels.
  • JP 07215261 A is a drive device for a wheel become known, in which the wheel has a projection on an internal ring gear is formed. This works with a Pinion to drive the wheel together.
  • the present invention is based on the object, a Sliding and braking aid for wheelchairs to create a high performance with low power is characterized and which is easy to assemble and disassemble.
  • the task is with a drive and brake assist device solved for wheelchairs, which can be fastened to the frame of a wheelchair is and at least one motor in both directions having drivable pinion on one of the rim of a Impeller of wheelchair attachable inner ring gear attacks.
  • the sprocket engaging the sprocket allows a Great translation even without gear.
  • the device can easily assembled and disassembled, with the inner ring gear can remain on the wheel.
  • the inner ring gear has on its radially outer Side hooked in cross section, in the rim of the Impeller mounted, circumferential mounting portion on.
  • This attachment portion preferably elastically deformable can be easily hung in the rim, if air is previously released from the tire of the impeller. Then the tire is inflated again and thereby also the attachment portion braced with the rim.
  • the Internal ring gear is so very easily retrofitted on the impeller to attach a wheelchair. He can also dismantled there Sliding and braking device remain because he the normal hand drive of the wheelchair via a gripping ring not with special needs.
  • each wheel can advantageously on each wheel an internal ring gear, with which a pinion is engageable, be fastened. Both pinions can be shared by a common Motor shaft to be driven.
  • the impeller 10 of a wheelchair not otherwise shown has, according to FIG. 1, a rim 11, an air-filled one Tire 12 and spokes 13 on.
  • a sliding and pushing Brake aid provided, of which an internal ring gear 14 and a pinion 15 are shown.
  • the inner ring gear 14 is attached to the rim 11.
  • the pinion 15 is from the shaft of a motor not shown here driven.
  • FIG. 2 illustrates, the internal ring gear 14 in his radially outer region a hook-shaped in cross-section Attachment section 14.1, which in the rim 11th is mounted.
  • At least the attachment portion 14.1 of Internal ring gear 14 consists of an elastically deformable Material, so that the attachment section 14.1 over the rim It is turnable when the air is let out of the tire 12 has been. Is then the tire 12 pumped up again, so is the attachment portion 14.1 between tire 12 and Rim 10 clamped.
  • the inner ring gear 14 can thus without Tool be attached to the impeller 10 of a wheelchair.
  • the Pinion 15 is driven by a shaft 16 which directly the Motor shaft can be. Of course it is, too possible, a gearbox and differential between engine and To provide pinion 15.
  • the pinion 15 can be in both Driving directions so that both support the Pushing the wheelchair as well as a support of braking the wheelchair with the device is possible.
  • the center distance for the toothing of pinion 15 and internal ring gear 14 is defined by a support roller 18 for which a bearing 17 is provided.
