Definitions

  • the present invention relates to an arrangement for a wheelchair wheel which comprises a wheel rim and a driving ring either permanently or detachably attached to the wheel, in conjunction with which a tyre is so arranged as to be detachably connected to the wheel rim, and the wheel exhibits 0 a frame attached to the wheel rim.
  • the principal object of the present invention is thus, in the first instance, to make available an arrangement which, amongst other things, solves the aforementioned problems in a simple and effective manner. Said object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that the wheel rim and the driving ring are formed from a common profile ring or are detachably attached to one another, in that the wheel rim is detachably attachable to said wheel frame, in that the wheel rim comprises a number of separate rim central parts extending radially from a centrally located hub, which central parts extend in a direction from said hub towards the wheel rim, in that the respective rim central part is divided into two and is formed from diverging spokes arranged in pairs that are connected to one another at their outer ends via a connecting part, in that the spokes extend in a curved fashion, and in that the spoke connecting parts are riveted, screwed or connected in some other way to the inner peripheral part of the rim.

  • the wheel 4 also exhibits a frame 7, which is connected to the wheel rim 1, whereby the wheel rim 1 is detachably attachable to said wheel frame 7.
  • the wheel profile ring 6 and preferably also the wheel frame 7 are appropriately made of aluminium or some other suitable metal.
  • the wheel profile ring 6 is appropriately produced from an extruded profile that has been bent into a circular wheel form and has been joined together at the ends 6A, 6B by welding. Plastic material can also be used alone or in combination with metal material.
  • Said wheel profile ring 6 is appropriately formed from a rim 1 exhibiting a U-shaped cross-sectional profile and a driving ring 2 exhibiting a ring-shaped cross-sectional profile and a connecting part 8 connecting them together.
  • Said wheel profile ring 6 exhibits a hollow profile
  • the driving ring 2 extends along the periphery of the wheel 4 with a diameter DI that is smaller than the diameter D2 of the wheel rim 1. Good transmission of force to the wheel 4 is still obtained in this way from the person sitting in the wheelchair and operating the driving ring 2 with his hands, but without the driving ring 2 making contact with the ground.
  • the wheel rim 1 comprises a number of separate rim central parts 12 extending radially from a centrally located hub 11, which central parts extend in a direction away from said hub 11 towards the wheel rim 1.

  • the spokes 13, 14 extend in a curved fashion, in conjunction with which five or more pairs of spokes are uniformly distributed around the periphery of the wheel rim 1.
  • Said spoke connecting parts 15 are appropriately riveted or screwed to the inner peripheral part 1A of the rim 1 or are attached to the rim by means of other connecting devices 16.
  • the hub 11 is located on a central part 18 displaced axially from the common plane 17 of the central parts 12 of the rim, which central part is formed from the common inner assembled parts 19 of the central parts of the rim.
  • Fig. 12 shows an example of a detachably attached driving ring 2, which is capable of attachment by means of fixing screws 50 and distance tubes 51 to the wheel frame 7, and more specifically is screwed through the respective radial spoke connecting part 15 on the outside of said wheel frame .
