Definitions

  • the present invention relates to a device for positioning a person, in particular a disabled person.
  • Armchairs which have a movable seat between two positions, one in which the person is seated and the other in which he is almost in a standing position.
  • This type of medical chair does not allow any variation since the backrest is fixed relative to the seat. In particular, it is not possible to make a sleeping plan, but everyone knows that the sitting position is still a tiring position.
  • existing armchairs have a footrest which does not participate in any other function than that of supporting the feet of the handicapped person when the latter is in the rest position or especially when the armchair has to be moved.
  • the present invention relates to a device for positioning in particular a disabled person between a total lying position and an almost upright position with all the intermediate positions, the operating mechanism of which is simplified so as to make it even more reliable and to reduce the cost price, the use of which remains simple with the possibility of voice control for example, whose different movements can be programmed, which can be associated with other transitic devices for the disabled, which has all the safety guarantees as regards braking for immobilization with respect to the ground during lifting to the position almost upright, which is adjustable in height according to the size of the disabled person and in particular his leg height, and whose seat itself can be adjusted according to the body size of the person in order to allow a passage in the almost upright position in the best conditions.
  • the device for positioning a person, according to the invention, in particular a disabled person, between a lying position and an almost upright position with all the intermediate positions comprises a frame which can be mounted on wheels and is characterized in that it comprises a movable horizontal seat thanks to the first drive means between two extreme positions, one for lying down and the other for lifting, a movable backrest thanks to second drive means between two extreme positions, the one horizontal to cooperate with the seat by forming a sleeping plane and the other inclined backwards with respect to the vertical so as to form a chair with the seat.
  • the device comprises an arm mounted by one of its ends for rotation relative to the frame thanks to a transverse axis and provided at its free end with a second axis of rotation parallel to the first , a seat plate supporting the seat itself and integral with this second axis, coupling means being interposed between these two axes.
  • the coupling means comprise a first fixed pinion coaxial with the first axis and integral with the frame, a second free pinion and coaxial with the second axis and a chain, mounted parallel to the arm, cooperating with these two gables.
  • the arm is adjustable in length so as to adapt the lifting height in the almost upright position to the morphology of the disabled.
  • the seat also comprises a front part provided with progressive retraction means when the seat is in the raised position.
  • These retracting means can advantageously comprise at least one arm secured to the front part, pivotally mounted relative to the seat plate in the vertical plane so that this front part tilts when the seat is raised.
  • the first drive means comprise a stick secured to the arm, the free end of which receives in an articulated manner the end of the piston of a jack whose body is articulated relative to the frame.
  • the backrest is mounted for rotation relative to a third axis parallel to the first and second axes, secured to the rear of the seat plate.
  • the second drive means applied to the backrest comprise at least a first free pinion mounted coaxially with respect to the second axis, at least a second pinion secured to the folder and secured to the third axis, a chain connecting these first and second gables, means for blocking the file in the raised position and at least one pivoting lever, integral with the first pinion cooperating with the frame to bring the file into the sleeping position when the seat is itself in the low position.
  • the device according to the invention further comprises, according to an improvement, a retractable footrest between a low position, in which it is concealed inside the frame and a high position in which it is juxtaposed with the seat when the latter is in the low position so as to form a complete sleeping surface.
  • the positioning device includes a frame 10, a seat 12, a backrest 14 and a footrest 16.
  • the frame is, in known manner, mounted on wheels 18 to make it movable.
  • This frame comprises at its upper part a frame 20 directly supporting the seat 12.
  • the seat 12 comprises an arm 22 rotatably mounted relative to the frame by one 24 of its ends thanks to a first transverse axis 26 and supporting at its other end 28 the seat plate 30.
  • This base plate is in fact mounted for rotation on a second axis 32 mounted for free rotation with respect to the end of the arm. Furthermore, there is provided a first pinion 34, coaxial with the first axis 26 and fixed in rotation relative to the frame, and a second pinion 36 integral with the second axis 32. These two pinions are connected together by a chain 38 constituting means coupling 40. This chain is parallel to the arm, the two strands passing on either side of this arm.
  • the seat also comprises first motor means 42 consisting of a butt 44 secured to the underside of the seat plate, of a jack 46 whose body 48 is articulated relative to the frame and whose piston 50 is articulated with respect to said butt.
  • This cylinder is advantageously an electric cylinder.
  • the seat 12 comprises a front part 52 provided with retracting means 54.
  • These retracting means comprise at least one arm 56 one of whose ends is integral with said front part and whose other end is articulated around '' a transverse axis 58 integral with the seat plate so that this front part is juxtaposed relative to the seat.
  • the backrest 14, as is better represented in FIG. 1, is mounted for rotation relative to the seat plate 30 around a third axis 60 integral with this seat plate. This third axis is parallel to the first and second axes.
  • Second motor means 62 are also provided comprising a first pinion 64 secured to the backrest, a second pinion 66, coaxial with the second axis 32, a chain 68 connecting these two pinions and a lever 70 integral with this second pinion, provided at its end. a roller 72.
  • the frame also comprises a guide cam, not shown, which cooperates with this roller so as to pivot the backrest in a horizontal position when the seat is in the low position.
  • the seat plate comprises means for locking the backrest in the sitting position.
  • the footrest 16 is retractable between a low position inside the frame without protruding outside and a high position in which said footrest is juxtaposed with the front part of the seat at the same level.
  • the footrest 16 is mounted on a deformable parallelogram 74.
  • This parallelogram 74 is articulated relative to a slide 76 with multiple sliding strands.
  • Motor means 78 are interposed between the frame and the slide so as to allow the strands of said slide to project forward.
  • a cable 81 connects the parallelogram 74 to the frame. The length of this cable is such that the parallelogram is at the height of the seat, it is to say fully extended, when the slide is protruding maximum.
  • the motor means 78 advantageously consist of an electric motor which drives a motor pinion 80 which in turn drives a chain tensioned by another pinion mounted free in rotation relative to the frame.
  • the chain is arranged along the longitudinal axis parallel to the slide.
  • braking means 86 are shown in detail in FIG. 4 and comprise on each side of the frame, at the front, a lever 88 pivoting relative to the frame and pressed towards the ground by return means, in this case a spring, so that a shoe disposed at the free end of the lever ensures braking by friction.
  • return means in this case a spring, so that a shoe disposed at the free end of the lever ensures braking by friction.
  • Means are also provided for lifting these levers when the device has to be moved. These lifting means can be made by those skilled in the art using cables connected to the stock in particular.
  • the backrest, the seat including its front part, and the footrest are in the same plane.
  • the seat 12 is in the low position
  • the lever 70 cooperates with the guide cam of the frame to lengthen the backrest
  • the jack is in the extended position and the parallelogram is projecting as much as the cable 81 is stretched while the different strands of the slide are in the extended position.
  • the disabled can act on the first motor means 42 to move from the bed position to the chair position.
  • it controls the electric actuator, the piston of which exerts a force on the stick, which makes the arm 22 of the seat pivot around the first transverse axis 26.
  • the lever 70 and its roller 72 leave the guide cam whose profile ensures the pivoting of the backrest relative to the third axis of rotation 60 until the locking means ensure the blocking in position of the backrest relative to the seat .
  • the motor means 78 drive the chain which causes the retraction of the slides telescopically, and has the consequence of folding the parallelogram 74 and lowering the footrest itself.
  • the seat plate 30 remains horizontal and moves away from the frame 20 of the frame 10.
  • the front part 52 is retracted by pivoting the arms 56 around the transverse axis 58, the front end of this front part 52 continuing to rest on the frame 20.
  • the seat is therefore dissociated from the front part which reduces its range so that only the buttocks of the disabled come to bear on said seat. If the handicapped person continues the movement, he finds himself in an almost upright position in which the height of the seat relative to the ground is substantially equal to his leg height.
  • the braking means 86 ensured the immobilization of the device relative to the ground.
  • control of these different movements is carried out using control buttons in the case where the disabled person has the use of one of his superior members. Otherwise, it is also possible to install a voice control or a mouth-operated pressure switch.
  • the whole device is of course dressed so as to give it a suitable aesthetic appearance and to ensure the comfort of the disabled.
  • armrests integral with the seat plate and liftable can be associated with the device in a simple manner.
  • This device is shown in the main embodiment with wheels, but it is also possible to adapt a large diameter wheel set with circular handle at the rear to ensure that the disabled person can move independently using his upper members.
  • the adjustable length arm allows you to adjust the chain tension at the same time as it allows you to adjust the standing position according to the length of the legs of the hanidcape.
  • the diameters of the pinions and the length of the lever make it possible to modify the angular speed of the backrest during the descent as well as the lifting effort while varying the angle of inclination of the backrest.
