Definitions

  • the present invention relates to the field of transport of people with motor disabilities, and more particularly relates to a foldable wheelchair.
  • this type of chair such as that described in FR-A-2 326 912, comprises a support frame carrying the backrest and the seat of said chair as well as two small front steering wheels and two large rear propulsion wheels, and formed of two symmetrical parts each consisting of a rectangular side frame. These two side frames are intended to move away (unfolded position for using the wheelchair) or to move closer (folded position for storing the wheelchair), in relation to each other, in order to reduce the bulk of the whole unused chair.
  • each frame consisting of two horizontal top and bottom rails, kept spaced apart by two vertical front and rear rails, is joined to the other by means of an articulation device which is most often in the form a crosspiece whose four free ends are rotatably mounted around four axes parallel to the four horizontal uprights of the side frames of said support frame.
  • this articulation device in addition to the significant weight of the crossbars, requires the presence of a system intended to compensate for the level differences between the two high horizontal beams and the two low horizontal beams of the two lateral frames during folding or unfolding the support frame.
  • This system generally formed by plungers engaging telescopically inside the vertical beams of the two side frames, has the immediate consequence of making the support frame heavier, which creates an additional difficulty for the user for the different manipulations.
  • the subject of the present invention is also a foldable wheelchair comprising a support frame carrying the backrest and the seat of the wheelchair as well as two front steering wheels and two rear propulsion wheels, said support frame being formed by two lateral rectangular frames intended for approach or move away from each other and each defined by at least two top and bottom horizontal beams kept spaced apart by means of at least two front and rear vertical beams, connecting means between the two frames, said connecting means comprising, on the one hand, an articulation device and, on the other hand, at least one first stretched fabric forming a seat between the two horizontal top rails, this chair being characterized in that it comprises, in addition, a second fabric stretched between the two horizontal bottom rails, the two said first and second fabrics being located on either side of the articulation device which is consisting of a single compass comprising two branches, the free ends of the two said branches being rotatably mounted around support axes arranged parallel to each other and in each of the side frames of said support frame.
  • such an armchair combines the following qualities: simple and space-saving structure of the entire armchair, reliability of use resulting from the simplicity of the maneuvers to be executed, small size of the folded armchair, weight of the frame - support reduced by half compared to the folding wheelchairs currently on the market.
  • the figure carried by this drawing is a three-quarter perspective view from above of a foldable wheelchair equipped with such a device.
  • This wheelchair is constituted by a support frame 1 formed of two lateral rectangular frames 1a and 1b, intended to approach or move away from one another.
  • These lateral frames 1a and 1b each consist of two horizontal top and bottom rails (respectively 2a, 2b and 2'a, 2'b) kept spaced apart by means of two vertical front and rear rails (respectively 3a, 3b and 3'a , 3'b).
  • This support frame 1 is mounted on the one hand on two small front steering wheels 4a and 4b and on the other hand on two large rear support wheels 4'a and 4'b, called propulsion.
  • the axes of rotation of the small front wheels 4a and 4b are fixed on the front vertical beams 3a and 3b, respectively, while the axes of rotation of the two large rear wheels 4'a and 4'b are fixed on the rear vertical beams 3 'a and 3'b, respectively.
  • the two rear vertical beams 3'a and 3'b of the support frame are extended at their upper part by two tubular uprights laires 5a and 5b, provided with handles 5'a and 5'b at their top.
  • the back and seat of the wheelchair ensuring the seated position of its occupant are made up of two fabrics, respectively 6 and 7, stretched first between the tubular uprights 5a and 5b, and the second between the horizontal beams high 2a and 2b of the support frame 1.
  • accessories found on a conventional wheelchair such as a footrest support 8, armrests 9, etc.
  • the two lateral frames 1a and 1b are joined by means of an articulation device 10 making it possible to fold or unfold the chair by bringing the two lateral frames together or away from them .
  • This articulation device consists of a compass, the free ends of the two branches 10a and 10b of which are associated with sleeves, respectively 10'a and 10'b, rotatably mounted around two vertical support axes 3 "a and 3" b arranged vertically and parallel to each other, at the first rear third of the two lateral frames 1a and 1b.
  • the position "first rear third" of the two vertical support axes 3 "a and 3" b was chosen according to the center of gravity of the chair and its occupant in order to strengthen the support frame 1.
  • the support axes 3 "a and 3" b are mounted integral each between the two bottom horizontal beams 2'a and 2'b, and two additional horizontal beams 2 "a and 2" b, arranged below the high horizontal beams 2a and 2b.
  • a second fabric 7 ' parallel to the fabric of the seat 7, is erected between the two horizontal bottom beams 2'a and 2'b of the support frame.
  • the branch 10b of the compass articulation device is provided with a shoulder 11 intended to cover part of the end of the other branch 10b when the latter is in the extension of the first one. It is understood that the purpose of this shoulder is to limit the angular expansion of the two branches 10a and 10b to a half-plane and more particularly, in this case, to the rear half-plane.
  • the object of the invention is to adapt on the branch 10b a pulling handle 12, making it possible to exert a force in the direction indicated by the arrow F It is also possible to put a handle on the other branch 10a intended to exert traction in the opposite direction to that of arrow F to allow the unfolding of the chair by opening said compass.
