Definitions

  • the object of the present invention is to improve wheelchairs for disabled.
  • the invention relates to a wheelchair which has the peculiar characteristic of enabling movement in all directions, either horizontally, on the basis of already known technical principles, or, independently, vertically so that the patient may assume any position from lying horizontally to standing, using slow movements and without physical efforts.
  • a wheelchair for disabled constiting of a frame comprising a chair-back, a seat, a leg rest and a foot rest connected to each other by hinges and two movable arms, characterized in comprising, in combination, bar and lever means, symmetrically positioned on both sides of the wheelchair and connected to each other horizontally by means of bars which are fixed to the frame in such a way that the motion of any one of said elements of the wheelchair will result in the motion of all the others, actuator means which control the abovesaid movements and means to control the actuator means themselves.
  • said actuator means are constituted by two linear electromagnetic actuators, one of which is hinged to the wheelchair seat while the other is hinged close to the leg rest.
  • Working of one or the other of said actuators determines the motion of all the elements constituting the wheelchair from a horizontal position to a vertical one.
  • the main advantage of having equipped the wheelchair with linear electromagnetic actuators lies in the fact that in case of failure the wheelchair will remain temporarily blocked as it is and will not return abruptly to its original position, creating the easily imaginable consequences for the patient.
  • said bar and lever means which are positioned symmetrically on-both sides of the wheelchair, include a horizontal bar, placed parallel to the seat and displaced towards the bottom, connected, at one end, to said seat by means of a semicircular bar and, in front, at the other end, to the leg rest, a profiled lever hinged, above, to said horizontal bar and, below, to the foot rest, transversal bars being provided for connecting the two symmetrical bar and lever systems rigidly together.
  • a second foot rest parallel to the abovesaid one, slightly higher up and rigidly fixed to the leg rest, is provided in order to avoid the weight of the legs on the first foot rest from having any effect on the inclination of the system of parallelisms.
  • said means to control the actuator means are advantageously a push-button control positioned on the arms, or levers, also positioned on the arms, or muscular impulse control, or vocal vibration control, or vocal code control means or remote drive control.
  • two belts on the chair-back and on the leg rest are provided so as to prevent the patient from slipping down from the wheelchair when in a vertical position.
  • said wheelchair comprises, in combination, two rear load-bearing wheels equipped with external rings, two front load-bearing idle wheels, one or two front rubber castors under the foot rest, two independent electrical motor reduction-units to control motion on the ground, a frame built with tubular elements to which the chair-back, the seat, the leg rest, the foot rest and the two movable arms are attached, two actuator means fixed, respectively, to the seat and to the leg rest, bar means and lever means hinged to said chair-back, leg rest and foot rest, and means to control said actuator means.
  • reference (1) indicates the chair-back of the wheelchair of the invention and reference (2) indicates one of the two movable arms.
  • the seat (7) and horizontal bar (5) are connected, hinged in (3) and (4) respectively, by means of a semicircular shaped bar (8).
  • said horizontal bar (5) is hinged in(10), being so connected to leg rest(11).
  • a shaped lever (16) is provided hinged to the leg rest in(14)and to the foot rest in (15).
  • FIG 1 also schematically illustrates the rear load-bearing wheels (17), the front idle load-bearing wheels (18) and the central load-bearing wheel (19).
  • the foot rest (20) is provided to avoid the weight of the patient on foot rest (12) from having any effect on the inclination of the other parts.
  • the motive power necessary for the horizontal and vertical movements of the wheelchair is generated by an accumulator (21) (figure 2).
  • All of the horizontal movements can be obtained by means of the separate controls (22) fixed to the frame near each rear wheel (17) which enable forward and backward motion of the wheelchair.
  • Rotational motion is transmitted to the rear wheels (17) by means of a roller (13) keyed to the shaft projecting from the motoq-;reduction-unit and compressed by a spring (not shown).
  • Figure 3 shows the linear actuators (23) and (24) hinged to the seat (7) in (25) and to the leg rest (11) in (26). Said actuators (24) and (25) are fixed below to the wheelchair frame (6) in (27) and (28).
  • the patient can operate actuator (24), which in its turn, takes effect on the leg rest (11) and, consequently, by means of the parallelisms illustrated in figure 1, on the foot rest (12), the seat (7), and the chair-back (1), so that the patient can assume any one of the intermediate positions between the one shown in figure 3 and the one shown in figure 4.
  • Figure 6 instead, shows an embodiment of the wheelchair according to the invention, which differs from the one described previously only in some of its constructional aspects, the main features which embody the innovative quality of the invention ' remaining unaltered.
  • actuator (23) can be fixed (32), instead of in (27) as in the case of the previous embodiment.
  • the semicircular shape bar (8) is in this case, replaced by a bar (30) which has the shape of a "seven".
  • the castor (19) is mounted on axis with the lever (11), instead of at the end of the foot rest (12) and is joined to the lever (11) by means of the element (31) which is slidable externally along said lever (11).
  • the element (31) is hinged to the lever (16) in (15) in such a way that when the patient brings himself into an erect position (see figure 5) equilibrium continues to be safeguarded by front castor (19).
  • This second embodiment is particularly suitable for street transportation both because of the possibility to provide for more than one accumulator (21) and because of the position of castor (19).
