Definitions

  • the invention relates to a wheelchair frame consisting of two opposite side frames, which are connected to each other via at least one transverse strut, a seat and a back frame, and each having a substantially horizontal, the seat receiving, upper strut and a lower strut connected thereto.
  • Such a wheelchair frame is for example from the DE 20 2004 005 653 U1 known.
  • the two struts of the frame are connected at their front end by being welded to a vertical tube. At their rear end, they are screwed together via a vertical strut, which can simultaneously accommodate a bearing for a drive wheel.
  • the back frame is bolted to the wheel bearing strut.
  • the known compounds are time consuming and expensive to produce.
  • the invention is therefore based on the object to simplify the structure of the side frame and to allow a quick installation.
  • a generic wheelchair frame is characterized in that the two struts are connected to each other at their end facing the back frame via a one-piece pipe bend, and that the diameter of the pipe bend is different in size at its two ends. It may be the inner diameter and / or the outer diameter at the two ends of different sizes.
  • the upper strut can be connected to the tubular frame by a sleeve or a screw connection.
  • the different diameter of the ends of the pipe bend allow to use conventional pipes for the lower strut and the back frame, which favors the modular structure of a wheelchair frame and reduces the manufacturing costs, since the storage can be kept small.
  • connectors are much faster to produce than screw or welded connections.
  • the lower ends of which are insertable into the upper ends of the pipe bends, are preferably arranged at the upper end of push handles.
  • the wheelchair consists of the frame, which has two opposite side frames 1, 2.
  • Each side frame 1, 2 consists of a horizontally extending upper strut 3 and a parallel thereto lower strut 4.
  • the struts 3, 4 are connected to each other at its front end via a strut 8 and at its rear end via the integral pipe bend 7.
  • the footrest bracket 9 are attached to the footrest 10.
  • the side frames 1, 2 are connected to each other via the seat 5 and the cross strut 11.
  • the one-piece pipe bend 7 is butted.
  • the inner diameter D 1 of the upper end 7 ' is larger than the inner diameter D 2 at the lower end.
  • the lower end 7 "of the pipe bend 7 is fixedly connected to the strut 4 by a hinge element 16 around which the cross strut 11 moves.
  • the hinge element 16 is inserted into the end 7" of the pipe bend 7.
  • the tubes 6a of the back frame 6 are respectively inserted, which have the push handles 12 at the opposite ends.
  • a fabric 15 is provided, which forms the backrest for the wheelchair.
  • a steerable front wheel 14 is still attached to the lower strut 4 and between the upper strut 3 and the lower strut 4 is in the rear area depending on a drive wheel 15 mounted vertically adjustable.
