Definitions

  • the present invention relates to construction of invalid wheelchairs intended for moving disabled persons with disturbed motor functions of the lower limbs.
  • One state-of-the-art invalid wheelchair is known to comprise an upholstered folding back, elbow rests, a seat, driving wheels, front wheels carrying the fork, and a footboard (GB Patent # 1,339,992, Cl. B62D 57/02, 1973).
  • the known invalid wheelchair suffers from too a sophisticated construction, an increased weight of the frame, and is inconvenient in use.
  • the invention has for its principal object to simplify the construction of the proposed invalid wheelchair and to render its use more convenient.
  • the wheelchair has bracing struts, pitmans, sockets connected to the frame and accommodating sleeves with a spring-actuated button which has a recess on its inner surface, while the frame is made up of two pieces transversely interconnected through bracing struts and adapted for adjusting the seat for width;
  • the back comprises two pillars articulated to the top surface of each of the frame pieces and spaced apart transversely from each other, said pillars being interconnected through bracers;
  • the upholstery is arranged on the surface of the pillars that faces the seat;
  • the pitmans are articulately mounted on the top surface of each of the frame pieces, while the pitman and the pillar of each of the frame pieces are connected to the elbow rest so as to establish a parallel crank motion;
  • the fork axle is associated with the sleeve through a retainer which comprises solids of revolution arranged in an annular groove provided in the fork axle and in the holes of the sleeve, and the spring-actuated button is adapted
  • the wheelchair be provided with guards located on the frame pieces and the pillars of the back and made of an elastic material.
  • sockets be connected to the frame by means of straps. It is necessary that the struts, pitmans, elbow rests, frame pieces, and pillars be made of light alloys, plastics, or composite materials.
  • the invalid wheelchair proposed herein comprises a frame 1 which carries a folding back 2 provided with an upholstery 3, elbow rests 4, a seat 5, driving wheels 6, front wheels 7 carrying a fork 8, and a footboard 9 (FIG.1).
  • the wheelchair has bracing struts 10, pitmans 11, sockets 12 connected to the frame 1 and accommodating sleeves 13 with a spring-actuated button 14 which has a recess 15 on its inner surface (FIGS.1, 2).
  • the frame 1 is made up of two pieces 16 transversely interconnected through the bracing struts 10 and adapted for adjusting the seat 5 for width;
  • the back 2 comprises two pillars 17 articulated to the top surface of each of the pieces 16 of the frame 1 and spaced apart transversely from each other, said pillars being interconnected through bracing struts 10.
  • the upholstery 3 is arranged on the surface of the pillars 17 that faces the seat 5, while the pitmans 11 are articulately mounted on the top surface of each of the pieces 16 of the frame 1.
  • the pitman 11 and the pillar 17 of each of the pieces 16 of the frame 1 are connected to the elbow rest 4 so as to establish a parallel crank motion (FIG.1).
  • An axle 18 of the fork 8 in associated with the sleeve 13 through a retainer which comprises solids 19 of revolution arranged in an annular groove 20 provided in the axle 18 of the fork 8 and in the holes of the sleeve 13, and the spring-actuated button 14 is adapted to cover the holes which accommodate the solids 19 of revolution so that the latter engage the recess 15 in the button 14 (FIG.2) when the latter is moving.
  • the wheelchair is provided with guards 21 located on the pieces 16 of the frame 1 and on the pillars 17 of the back 2, said guards being made of an elastic material.
  • the sockets 12 are connected to the frame 1 by means of straps 22 (FIG.2).
  • the elbow rests 4, struts 10, the pitmans 11, the pieces 16 of the frame 1, and the pillars 17 are made of light alloys, plastics, or composite materials.
  • the wheelchair has also springs 23 and bearings 24. Annular grooves 25 (FIG.2) are provided for the straps 22.
  • the pieces 16 of the frame 1 are similar in shape and size and feature an equally strong open thin-walled profile.
  • Provision of the wheelchair construction elements made of light alloys, plastics, or composite materials and manufactured by the casting or moulding technique helps reduce labor consumption required for wheelchair manufacture and produce a lighter, adequately rigid and cheap wheelchair construction.
  • the bracing struts 10 are unequal in length, whereby the structural dimensions of the wheelchair can be varied so as to use it in both child and adult versions.
  • the button 14 is let to move down so that the recess 15 be opposite to the solids 19 of revolution (i.e., balls).
  • the button 14 is lowered and the axle 18 of the fork 8 is fitted into the sleeve 13 until the axle rests against the sleeve end.
  • the button 14 is released, with the result that the edge of the recess 15 forces the solids 19 of revolution from the sleeve 15 into annular groove 20.
  • the button 14 locks the solids 19 of revolution, thus preventing them from disengaging the annular groove 20 in case of inadvertent pulling down of the axle 18.
  • the user travels on the wheelchair by rotating manually the driving wheels 6.
  • the invention simplifies the construction of wheelchair and renders its use more convenient.
  • the invention can find application in the manufacture of invalid wheelchairs.
