Definitions

  • the innovation relates to a wheelchair of the type mentioned in the preamble of claim 1.
  • a wheelchair of the type in question is known from the company publication "MEYRA wheelchairs and rehabilitation aids" from MEYRA Wilhelm Meyer GmbH & Co. KG, Meyra-Ring, D-4925 Kalletal-Kalldorf. If such a wheelchair is to be folded up from the use position into the non-use position, the side parts are generally pressed together by means of handles attached to them at the top rear, which are normally used to move the wheelchair. This is often difficult because of the frictional forces in the telescopic guides, which are particularly aggravated by jamming and jamming. Folding is therefore often only possible by pulling up the upper parts of the side parts, which requires special handling or a change of grip.
  • the innovation is based on the task of creating a wheelchair of the type in question, in which the folding of the side parts from the use position into the non-use position is facilitated.
  • the basic idea of this teaching is to reduce the frictional forces in the telescopic guides, in particular, in that the top parts are each supported by a contact roller on contact tubes, which are located on the bottom parts and extend parallel to the guides in the range of motion of the top parts.
  • these roles absorb a substantial part of the compressive forces and transmit them in a rolling manner and thus with vanishing frictional forces.
  • the friction forces in the guides are therefore significantly reduced, so that the folding is facilitated overall.
  • the contact pipes are expediently extended upwards and curved backwards, where they form or have handles.
  • the investment pipes therefore do not represent any additional effort, and the effort for the investment rollers is very low. You can be conveniently located at the end of a short tube that extends in extension of the associated rotatably held tube part.
  • the wheelchair shown schematically in FIGS. 1 and 2 has two side parts 1 and 2, each consisting of a lower part 3 or 4 and an upper part 5 or 6 exist, which, as can be seen in particular from FIG. 2, are movably connected to one another in the vertical direction by telescopic guides.
  • the telescopic guides consist of tubes 7 to 10, which are held vertically displaceably in tubes 11 to 14 of the lower parts 3 and 4.
  • the upper ends of the tubes 7 and 8 or 9 and 10 are welded to bushings 15 and 16 or 17 and 18, the axis of which extends transversely to the guide direction of the tubes 7 to 10 and in which the ends of tube parts 19 and 20 engage rotatably.
  • wheels 31 to 34 which are designed and arranged in a known manner, which need not be explained in more detail.
  • the rear, vertical tubes of the lower parts 3 and 4 form in their upper region bearing tubes 35 and 36, on the inside of which bearing rollers 37 and 38 rest, which are located at the outer ends of the bushings 16 and 18.
  • the contact tubes 35 and 36 continue upwards over the guide area and are curved or angled backwards so that they form handles 39 and 40.
  • a seat 41 in the form of a flexible belt which wraps around the pipe parts 19 and 20 with its edges.
  • the rough chair is in its position of use, in which the side parts 1 and 2 have their maximum distance essentially determined by the seat 41, in which the Bars 27 and 28 have their maximum spread.
  • the handles 39 and 40 are moved towards one another, the abutment rollers 37 and 38 rolling inside on the abutment tubes 35 and 36 and thus all of the essential ones due to the folding Forces are transmitted largely smoothly, with the result that the wheelchair can be folded from the use position into the non-use position without great effort.
  • the side parts 1 and 2 and their respective lower parts 3 and 4 and upper parts 5 and 6 do not necessarily have to consist of bent or welded steel tubes. It can also be flat, plate-shaped side parts, and the guides for the two respectively associated lower and upper parts can also be designed differently in each person skilled in the art.
