Definitions

  • the subject of the invention is a movement device for a disabled person which allows, even to a severely handicapped person, to move around and regain a certain autonomy in a housing of current construction for able-bodied people.
  • the main object of the invention is to provide a movement device for disabled person which differs from wheelchairs by a reduced size allowing its passage through any door opening of current width, by a low weight allowing, thanks to its low size, its transport in the trunk of any car, this device however requiring only a low energy and a low amplitude of a single upper member to make possible any desired movements inside a housing a disabled person.
  • a further object of the invention is to achieve a device as specified above with which it is possible to move with great precision over very small distances, which is often necessary in a congested housing.
  • Another additional object of the invention is to provide a device of the above type which is capable, in addition, of producing a reeducation effect on the part lower limbs during use by a disabled person using their upper limbs.
  • the main object of the invention is achieved with a displacement device comprising a wheeled chassis having at least one driving wheel and a steering wheel in which the chassis comprises bearing surfaces intended to support the feet of any common seat.
  • a displacement device comprising a wheeled chassis having at least one driving wheel and a steering wheel in which the chassis comprises bearing surfaces intended to support the feet of any common seat.
  • the chassis comprises bearing surfaces intended to support the feet of any common seat.
  • a chair for example, having a seat to receive the disabled person,
  • the frame ends in a vertical direction at a level lower than that of the seat and it serves to support on the one hand, a drive means having an operating member located on one side of the space intended to be occupied by the seat, on the other hand, a control mechanism for the wheel or steerable wheels having a steering member located on one side of the space intended to be occupied by the seat.
  • the drive means comprises a shaft arranged in the transverse direction of the device at a level lower than that of the seat cushion and having its two end parts accessible respectively from one side and the other from the location reserved for headquarters.
  • Each of the end parts of the transverse shaft is intended to receive a removable flywheel which can be substituted, as a variant, at will, a ratchet lever also removable.
  • the control mechanism of the 4 steering wheels comprises a handlebar located at a level lower than that of the seat cushion and having a neutral position in which it is arranged in the transverse direction of the device, this handlebar having at each of its two end parts opposite a telescopic extension.
  • the chassis comprises two parallel upright flanges, spaced in transverse direction of the device and the bearing surfaces are arranged outside these two flanges.
  • Each flange comprises two spaced sheets and a non-steering wheel is placed between the two sheets of each flange, at least one of these wheels being surrounded by a belt, preferably of the notched type, which extends to a pulley wedged on a transverse shaft on which there is at least one drive member, the belt passing around the rolling surface of the wheel in question.
  • the chassis is equipped with two footrests mounted with a possibility of displacement between a first position in which they rest on the ground and a second position in which they are raised above the ground.
  • the footrests have an extension and are joined by the extension to a transverse bar supported by the frame and pivoting between an advanced position putting the footrests in their first position and a position moved back putting the footrests in their second position.
  • the drive wheel is fixed in rotation on a "11 transverse shaft on which are mounted two cams by means of clutch and disengage in correspondence each respectively with an extension of a footrest, each extension being spaced from the corresponding cam when the footrest occupies its first position and being in contact with this same cam when the footrest occupies its second position and the cams are made active by the clutch means.
  • a device essentially comprises a chassis 1 mounted on wheels preferably comprising two steered wheels 2 - which are the rear wheels in this example - and two non-steered wheels 3, 4 of which only one, the wheel 3, is a Driving wheel.
  • This frame 1 includes bearing surfaces 5 intended to support the four legs of a seat such as a chair 6 shown in a finer line in FIG. 2 only.
  • the bearing surfaces 5 are as close as possible to the ground on which the wheels 2 to 4 roll; they can be arranged and dimensioned to suit a single type of seat 6 but it is preferable in the spirit of the invention, to provide bearing surfaces 5 capable of indifferently receiving several types of seat 6. This is however, seats of any common use whose width is such that they pass without difficulty through the openings of current doors inside the accommodation.
  • the frame 1 is hardly wider than the seat 6. It may be desirable, for better stability, that certain bearing surfaces 5, those of the rear in the example described here, are surrounded by a border which opposes the sliding of the corresponding foot.
  • the seat 6 has a seat 8. In the height direction from the ground, the frame 1 ends at a level lower than that of the seat 8, so that it is below the latter. .
  • the chassis 1 serves to support a drive means for the driving wheel 3; this means includes a tree 9 extending transverse to the device and located near the top of the latter, a short distance below the seat 8.
  • the shaft 9 On each side of the space intended for the latter, the shaft 9 has a part extreme free reserved for an operating device.
  • Each end part is designed to receive a steering wheel 10 or to receive a ratchet lever 11.
  • Either of these operating elements 10, 11 can be used to move the device, depending on the validity of the one or the other upper limb of the person sitting on the seat 8 and according to the kind of movement (rotation of the steering wheel or alternative movements of the ratchet lever 11) which he prefers to execute.
  • the two operating members are removable, interchangeable on one side and on the other of the device.
  • the chassis 1 also serves to support a control mechanism for the steered wheels 2.
  • This mechanism includes a handlebar 12 which has a neutral position for displacement in a straight line of the device in which it is arranged in a direction transverse to the latter.
  • the handlebar 12 is provided with a telescopic extension 13 which can be retracted as on the left part of FIG. 3 or which can be extended as on the right part of the same FIG. 3.
  • Each extension 13 is a steering device which can be made accessible on either side of the space intended for the seat 8 of the seat 6, depending on the mobility of one or the other upper member of the disabled person.
  • Each extension 13 can be extended on the side and retracted when necessary, to pass through the opening of a door or for the operation of the steering wheel 10 or of the lever 11.
  • connection between the handlebars 12 and the steered wheels 2 is made in a manner known per se using a vertical rod 14 (FIG. 4) provided with a control arm 15 articulated by means of an auxiliary arm 16 with an articulated parallelogram 17 with which the wheels 2 are coupled for their orientation.
  • the chassis 1 comprises two spaced parallel flanges 18, 19 which are themselves each composed of two parallel sheets 18A, 18B and 19A, 19B, held spaced apart by spacers.
  • the bearing surfaces 5 are just outside the width defined by the distance which separates the outer sheets 18A, 19A.
  • each flange 18, 19, the sheets 18A, 18B and 19A, 19B are spaced by the distance necessary for the establishment between them of non-steerable wheels 3, 4.
  • These wheels 3, 4 are wedged on a transverse shaft 20 and the drive wheel 3 is surrounded by a belt 21 which extends between the two sheets 18A, 18B of the flange 18 up to a pulley 22 wedged on the shaft 9.
  • the wheel 3, the pulley 22 and the belt 21 are notched.
  • the belt 21 passes around the rolling surface of the wheel 3 so that it is clamped between the latter and the ground, under the weight of the device, the chair and the person seated on the latter.
  • There is an ankle type drive with which any slip effect is practically eliminated. Thanks to the notches of the belt 21, the slightest movement of the operating member 10., 11 causes a corresponding movement of the device. It is therefore maneuverable with great precision.
  • the device described so far could be used provided that the lower limbs of the person sitting on the seat 6 remain hanging in front of the latter.
  • footrests 23 supported by the frame 1 between the flanges 18, 19, in front of the location intended to receive the seat 6.
  • each footrest 23 has an extension ment 24 inclined rearward at an angle of approximately 30 ° with the ground and extending between the flanges 18, 19 to a movable transverse bar 25.
  • the latter is pivotable between the flanges 18, 19 between an advanced position and a retracted position at which it is shown in Figure 1 and at which the footrests 23 occupy an elevated position above the ground.
  • This raised position provides sufficient ground clearance for movement, for example to pass over a carpet or a threshold at the edge of a carpet.
  • This position is called the second position, the first position being that in which the footrests 27 rest on the ground by their underside, when the movable crossbar 25 has been brought to its advanced position.
  • This movable bar 25 is pivotable in this example because it constitutes the lower side of a frame whose upper side 26 is supported and articulated between the two flanges 18, 19. To this upper side 26 is fixed a lever 27 which s 'extends rearward and which is accessible behind and below the seat 8 of the seat 6 ( Figure 2).
  • This lever 27 passes along a vertical tube 28 which contains and guides the vertical rod 14 to which the handlebar is fixed 12. Hooking means (not visible in the drawings) are provided for hooking the lever 27 au.tube 28 in correspondence with the advanced position and with the retracted position of the movable crossbar 25.
  • the extensions 24 are joined to the movable crossbar 25 by their upper end. In the vicinity of their lower end by which they are joined to the footrests 23, there is between the flanges 18, 19 a transverse support bar 29, fixed, on which the extensions 24 rest and slide freely.
  • This fixed support bar 29 has the effect that when the movable crossbar 25 is put in its advanced position, the extensions 24 move forward and tilt slightly around this fixed support bar 29.
  • the footrests 23 come into contact with the ground at least by their extreme edges, so that a disabled person who walks by dragging or sliding his feet on the ground can nevertheless climb on the footrests 23 without having to actually lift his feet and without risking being unbalanced by standing on one leg.
  • this person sits on the seat 6 after having turned over in a standing position on the footrests 23, another person operates the lever 27 and hooks it to the vertical tube 28 in the lifting position of the footrests 23 .
  • the shaft 20 which carries the wheels 3, 4 passes below the extensions 24, to a higher position and further back than that of the fixed support bar 29. Therefore, when the movable transverse bar 25 is brought to in its advanced position, the extensions 24 are more distant from this shaft 20 since they have been advanced and they have tilted forward around the fixed support bar 29.
  • the shaft 20 carries an axially sliding sleeve 30 which itself carries two eccentric cams 31 which each correspond respectively to an extension 24. These cams 31 can be engaged or disengaged relative to the shaft 20 by means clutch 32 provided between this shaft 20 and the sleeve 30 which can be made active or inactive depending on the position in the axial direction of the sleeve 30. In Figure 4, the clutch means 32 is inactive.
  • Each extension 24 is provided on its underside with a longitudinal reinforcing rib 33 with which the surface of the corresponding cam 31 can cooperate when the sleeve 30 has been moved to make the dog clutch means 32 active.
  • This axial movement of the sleeve 30 and cams 31 until they are placed below the ribs 33 is possible when the movable crossbar 25 has been put in its advanced position and the footrests 23 touch the ground.
  • the extensions 24 come to rest by their reinforcing ribs 33 on the cams 31 , so that they are raised above the fixed support bar 29.
  • the shaft 20 rotates the sleeve 30 and the cams 31 eccentrically.
  • the extensions 24 and the footrests 23 are then raised and lowered by the amplitude determined by the profile of the cams 31 repeatedly.
  • the movable crossbar 25 is joined by an axis to the short sides of the frame of which it is a part.
  • the cams 31 may be of the type with adjustable offset.
  • the amplitude of the successive movements of lifting and lowering imposed on the feet is small but it is useful in many circumstances against ankylosis or at the beginning of rehabilitation exercises.
