Definitions

• the invention relates generally to the ergonomics of wheelchairs. More specifically, the invention relates to a wheelchair of the type comprising at least one chassis having rear, front, right and left sides, a seat supported by the frame, and on each of the right and left sides, a wheel rear rotatably mounted about a horizontal axis connected to the frame, a front wheel rotatably mounted about a horizontal axis carried by a yoke itself rotatably mounted about a corresponding vertical axis connected to the frame, and a rests foot linked to the chassis and arranged at the front of the seat. Controlled movement of a standard wheelchair requires the person using it to apply co - ordinated efforts on both sides of the wheelchair and a person with hemiplegia is unable to exercise.
• the main purpose of the invention is to provide a wheelchair adapted to hemiplegic persons and overcoming at least some of the disadvantages and limitations previously enumerated.
• the wheelchair of the invention is essentially characterized in that, on a first at least of the right or left sides, the foot is linked in rotation, around the corresponding vertical axis, to the yoke carrying the front wheel on this first side.
• the person using the chair of the invention can ensure the direction of a simple way by immobility, adduction, or abduction of the hip, the corresponding effect is maintained in place or to separate in one way or the other the footrest linked in rotation with the front steering wheel, and thus to advance this chair in a straight line, towards one side or towards the other, with a radius of gyration all the more small as the movement of the hip is important.
• the chair of the invention can be obtained by adapting a standard chair without requiring specific manufacture.
• the chassis comprises, on the first side at least, a front upright relative to which the footrest and the yoke carrying the front wheel are mounted in rotation about the corresponding vertical axis.
• the front upright comprises a hollow tube opening towards the ground and in which passes the vertical axis of rotation of the yoke of the front wheel, and that the foot is rotatably connected to the fork of the front wheel by means of a rod passing through the tube.
• each rear wheel can be carried by a corresponding rear upright of the frame.
• the invention can easily be implemented on a chair comprising at least one handrail integral in rotation with a corresponding rear wheel, in which each rear wheel is fixed to the frame in a demountable manner, and whose frame is folding.
• FIG. 1 is a perspective view of a wheelchair of known type
• Figure 2 is a perspective view of a wheelchair according to a preferred embodiment of the invention
• FIG. 3 is an enlarged view of a detail of FIG. 2;
• FIG. 4 is a partial and exploded view of the elements illustrated in FIG.
• the invention relates to a wheelchair comprising in particular, in known manner
• the frame 1 is preferably folding, in which case the seat 2 is flexible or itself folding.
• the generally asymmetrical general shape and the use of such a chair define a rear side AR, a front side AV, a right side DR and a left side GA.
• the rear wheels 31 thus comprise a right rear wheel and a left rear wheel
• the front wheels also include a right front wheel and a front wheel.
• the footrests include a right footrest and a left footrest.
• Each rear wheel 31 is rotatably mounted about a horizontal axis 310 fixed, in operation, with respect to the frame 1, the hub defining the axis of rotation 310 of this wheel being for example demountably supported by a post corresponding rear 11 of the frame 1.
• Each of the rear wheels 31 typically has a diameter substantially larger than that of the front wheels, each of these wheels 31 or at least one of them can also be provided, in a manner also known per se, with a handrail 311 secured to the wheel 31 and for driving it in rotation about the corresponding axis 310.
• Each front wheel 32 is rotatably mounted about a horizontal axis 320 carried by a yoke 321 which is itself rotatably mounted about a corresponding vertical axis 3210 connected to the frame 1.
• each footrest 4 is connected to the frame 1 and disposed at the front of the seat 2.
• the footrest 4 on at least one of the right or left sides, is rotatably connected around the corresponding vertical axis 3210 to the yoke 321 carrying the front wheel 32 on this side.
• one of the footrest 4 is fixed relative to the frame 1, and the other is thus linked in rotation to the yoke 321 which carries the front wheel 32 located on the same side as this footrest.
• one of the footrests 4 and the clevis 321 of the corresponding front wheel 32 can be mounted in rotation, together and around the vertical axis. corresponding 3210, on or in an amount before 12 of the chassis 1.
• the amount before 12 ( Figure 3) consists essentially of a hollow tube opening towards the ground and through which a rod 121 (FIG.
• the rod 121 extends along the vertical axis 3210 of rotation of the yoke 321 of the front wheel 32, and makes this yoke 321 integral in rotation about the vertical axis 3210, the footrest 4 located on the same side than this screed.
• the axis of the footrest is also mounted on two ball bearings whose height is compensated by changing the height of the wheel 32 in the yoke 321.
