Definitions

  • the invention relates to a folding wheelchair with a base supported by wheels, on or on which a seat, a backrest and side armrests are arranged.
  • DE GM 89 13 468 proposes to form the cross strut in a folding wheelchair as a double V-shaped folding tube scissors with adjustable hinge points.
  • DE GM 93 14 406 describes a kit from which, using individual, held in different sizes reproached parts, a dimensioned in the dimensions of the user wheelchair is mounted. Here, however, there remains the need to keep individually adapted to the size of stock parts.
  • the object of the invention is therefore to provide the constructed according to the type mentioned folding wheelchair by simply constructed and easy-to-use means with a possibility for adjusting the width, thus making the provision of wheelchairs different widths or components of different widths unnecessary , Furthermore, a high stability and security should be ensured despite adjustment.
  • a folding wheelchair with a base supported by wheels, on or on which a seat, a backrest and side armrests are arranged, the base is formed by a cross strut, the struts each of an inner and consist of two outer tubes, which are connected by a thread variable length.
  • This construction offers the advantage that, despite the simple adjustment, a high degree of stability and safety is achieved, since with a thread an unintentional displacement or even slipping out is largely precluded. Also allows the construction of a substantially continuous adjustment.
  • the position of the inner and outer tubes is fixable to each other by a lock nut.
  • a longitudinal mark can be provided in the thread.
  • circumferential markings at certain intervals. These can, for example, consist of numbers, letters or colors.
  • width adjustment according to the invention can be supplemented by measures known per se by a Weg Brunswickn- and / or seat depth adjustment.
  • the cross brace 10 in Fig. 1 is formed by two struts, each consisting of an inner tube 11 and two outer tubes 12.
  • the inner tubes 11 are in a conventional manner via a hinge connection to the crossbar 10 united.
  • the inner tubes 11 are connected via threads 13 with the outer tubes variable in length.
  • the inner tubes carry an external thread and the outer tubes have the matching internal thread.
  • the selected length adjustment is additionally secured by lock nuts 14.
  • the outer tubes 12 are hinged to the side frame 8.
  • the inner tube 11 has advantageously at its ends opposing right / left-hand thread, so that for adjusting only the inner tube 11 needs to be rotated without having to solve the outer tubes 12 from the frame of the wheelchair.
  • a wheelchair 1 conventional type are installed in the two cross struts 10 of FIG.
  • This includes small front wheels 5 and larger rear wheels 6, which are fixed to a base frame 9.
  • a side frame 8 On these rests a side frame 8 with the armrests 4.
  • a spar 2 Between two of these parts 8, 9 is a spar 2 for attachment of a seat.
  • the backrest 3 has two handles 7 with corresponding struts 15, are stretched between the straps, as well as between the bars 2 to form the seat (Fig 3 + 4).
  • Fig. 3 illustrates the width adjustment of the wheelchair.
  • the cross braces 10 are elongated by rotating the inner tubes 12, whereby the cross brace 10 is stretched and the outer tubes 1 and also the entire side frame is offset outwardly, as indicated by the positions 7 'for the handle and 6' for the rear wheel.
  • seat and back consist of individual straps, which are adjustable in length.
  • the advantage of using separate belts is also that they can be adapted to the individual physique, ie the individual straps can be different lengths.
  • Fig. 4 shows the construction of such a backrest or seat according to the invention.
  • the longer belt sections 21 are pushed from above through the eyelets 20 and held at the bottom in Velcro.
  • the backrest and the seat are adjustable in a very simple manner.
