Description

ARMCHAIR PARTICULARLY FOR SICK A

REDUCED MOBILITY

  The present invention relates generally to an apparatus for lifting and

  transport a person with reduced mobility.

  When a person can no longer get up and move around, his relatives, if he is at home, or the nursing staff, if he is hospitalized, must wear him each time he has to change position, for example

  example to get her from her bed to her chair.

  This requires great strength and a great habit because it is necessary to lift the patient, carry him and move around, at least make a quarter turn on himself

to drop it off.

  There are many facilities designed to provide assistance to people caring for the sick.

reduced mobility.

  Some equipment is generally in the form of a bracket to which a harness or straps are attached that have been placed under the body of the bedridden patient. These devices make it possible to lift a patient from

his bed and carry it.

  These devices have many drawbacks. They are generally bulky which limits their use in hospitals where space is provided below and around beds, armchairs, bathtubs. The installation and removal of the harness or straps is not easy. The patient is more or less curled up on himself in an uncomfortable position during the transfer and undergoes an unpleasant pendulum movement. Equipment has been proposed which makes it possible to solve certain drawbacks of harness devices.

or straps.

  It is an armchair made up of a supporting frame, movable in translation in the direction

  vertical, a seat on which the patient sits.

  The chassis has a base carrying four casters and a vertical beam. The base is of low height in order to pass under beds or armchairs arranged close to the ground like those which one generally has at home, said base is more

  shaped like a U so that the seat can be placed

above a toilet bowl.

  To lift a patient, we approach the chair from the bed and adjust the height of the seat so that it rests on the bed next to the patient. This one sits on the seat on which it can be maintained if necessary by a belt, a file and a support bar are arranged respectively behind and in front of the patient. The seat is then lifted away from the bed and

  allow the chair to move.

  The patient thus seated on the chair may be

transported to any other place.

  This chair solves the problems of space, ease of use and discomfort of the previous devices but does not provide a complete answer to the problems encountered by people in charge of patients.

with low mobility.

  To be able to be transported using such a chair, the patient must be sufficiently toned to be able to lift and sit by himself otherwise it is necessary to carry it. He must also be able to sit up because the backrest provides only support and cannot keep the patient in a sitting position. This limits

  the possibilities of using the wheelchair.

  In addition, the vertical beam is on the side of the patient when he is seated on the seat which prohibits certain uses, for example, one cannot approach the armchair of a table for the catch of meal and it is necessary to transfer the

  sick on another chair or chair.

  The present invention aims to provide a chair of small size, easy to use even for a patient who can not move by itself, and which can be used in a large number of circumstances so as to avoid the transfer of the patient on another medium. To this end, the invention provides a chair particularly intended for patients with reduced mobility, of the type comprising a frame composed of a generally rectangular vertical frame and a base carrying casters and a seat consisting of at least one seat, characterized in that said seat base comprises a support plate mounted fixed in rotation relative to the frame and carrying, in rotationally movable about an axis which is perpendicular thereto, an upper part of said seat, or cushion, so to be able to rotate the cushion relative to the vertical frame of the chair, the support plate remaining fixed in position by

report to the building.

  The armchair according to the invention is also remarkable in that - the seat consists of the seat, a backrest and two armrests, - said backrest is mounted movable in rotation relative to the seat so as to be able to be arranged either perpendicular to the seat, or in the same plane as the seat and a locking device for said backrest keeps it in the position for which it is perpendicular to the seat, - the armrests are mounted on either side of the backrest being movable in rotation between a position for which they are generally arranged in the plane of said backrest, and a position for which they are perpendicular to said backrest, said armrests being able to be locked in the position for which they are perpendicular to the backrest, - the support plate is mounted on the chassis by means of a support bracket,

4 2736821

  - the support bracket has means which are fixed to the support plate and means which are fixed to the frame of the chair, - the support bracket is fixed to end caps of the chassis forming part of a seat lifting device allowing to adjust the height of said seat at will relative to the ground, - the lifting device consists of a frame mounted movable in translation on the vertical frame and a control means ensuring the movement of said frame upwards or bottom, - the rotation of the cushion relative to the support plate is ensured by the installation of a mounting comprising circular grooves formed in the upper surface of the support plate and in the surface

bottom of the cushion.

  The invention will be better understood thanks to the

  description which will follow given by way of example not

  limiting with reference to the accompanying drawings in which: - Figure 1 is a schematic perspective view of the chair according to the invention, - Figure 2 is a schematic perspective view of the frame of the chair according to the invention, - Figure 3 is a top view of the seat support bracket, - Figure 4 is a top view of the seat laid flat. The chair according to the invention is generally made up of a frame 1 and a seat 2. The frame consists of a generally rectangular vertical frame 11 and of a U-shaped base 10 carrying casters 12, of which

  at least one is fitted with a brake.

  For reasons which will be better understood later, the U-shaped base 10 has a first branch 13 merged with the bottom of the vertical frame, a second branch 14 disposed parallel to said frame and at a distance therefrom and a third branch 15 connecting said first and second branches arranged perpendicularly to these and to the frame. This third branch connects said first and second branches at one of their ends which gives the base 10 its U-shape. The vertical frame 11 and the base 10 can be designed in the form of two separate parts that the one connects to the other, for example by finger fitting provided for this purpose with the establishment of a safety means avoiding inadvertent disassembly. Such an embodiment makes it possible to dismantle the chair in order to

  store, for example in a car trunk.

  To facilitate understanding of the description

  we define by front of the chair the space located on the side of the seat relative to the vertical frame, rear of the chair

  the space located on the side of the vertical frame opposite the chair.

  The left and the right will be defined in relation to these

  directions by looking at the front of the chair.

  In the embodiment shown in the drawing, the third branch 15 of the base 10 is arranged on the

left of the chair.

  Seat 2 consists of a seat 20, a backrest

  21 and two armrests 22, preferably ergonomic.

  The backrest 21 is mounted movable in rotation relative to the seat 20 by means not shown in the drawing so as to be able to pass from a position for which it is perpendicular to the seat as shown in FIG. 1, to a position for which he is in the

  same plane as the seat 20 as shown in FIG. 4.

  The means ensuring the movable mounting in rotation of the backrest 21 relative to the seat 20 comprises a device for locking said backrest in the position for which it is perpendicular to the seat 20, possibly with a stable blocking position

intermediate to around 60.

  The armrests 22 are mounted on either side of the backrest 21 while being movable in rotation between a position for which they are generally arranged in the plane of said backrest, either upwards as shown in FIG. 4 or downwards, and a position for which they are perpendicular to said backrest as shown in Figure 1. Said armrests can be locked in

6 2736821

  the position for which they are perpendicular to the backrest. According to the invention, the seat 20 of the seat comprises a support plate 23 mounted fixed in rotation relative to the frame and carrying, in a manner movable in rotation about an axis which is perpFendi (, it it- ,, the part

  upper or cushion 26 of said seat.

  The rotation of the cushion 26 relative to the support plate 23 can be ensured by any assembly of known type, such as for example as shown in the drawing an assembly comprising circular grooves, shown diagrammatically by the circle 24 in dotted lines in FIG. 4, formed in the upper surface of the support plate 23 and in the lower surface of the cushion 26 between which can

for example circulating balls.

  Thanks to these means, it is possible to rotate the cushion 26, backrest 21 and armrests 22 assembly relative to the frame of the chair, the support plate remaining fixed in position relative to said frame. We will of course take care to size and conform the various

  seat elements to allow this rotation.

  The support plate 23 is mounted on the chassis 1 by means of a support bracket 4 having means attaching to the support plate formed by two branches 42 parallel to each other and means attaching to the frame 11 of the chair formed of two branches 41 parallel to each other. The branches 42 and 41 are

  arranged on either side of an amount 40.

  Different means of fixing the legs 42 to the support plate can be used, such as insertion into bores drilled in the thickness of said plate

  support or in flanges fixed to said plate.

  The branches 41 are fixed to the frame by any known means, for example as shown in the drawing by inserting

  in end pieces 31 carried by said frame.

  Said end pieces 31 are part of a device 3 for lifting the seat allowing the height to be adjusted as desired

said seat relative to the ground.

7 2736821

  This lifting device consists of a frame 30 mounted movable in translation on two bars 16 of the frame

vertical 11.

  The frame 30 carries said end pieces 31. A control means 32 such as a manual assembly, an electric motor, a hydraulic or pneumatic cylinder is disposed between the branch 13 of the frame 11 and the frame 30 so as to ensure the movement of said frame 30 up or up

bottom along the bars 16.

  When it is desired to position a bedridden patient on the chair, it is first of all necessary to rotate the cushion - backrest - armrest assembly relative to the support plate so as to position the backrest 21 perpendicularly to the vertical frame 11. The the armchair is then approached the bed while adjusting the height of the support plate 23 relative to the ground so that

  said support plate rests on the patient's bed.

  The backrest and armrests are then brought into the position for which they are in the same plane

than the seat 20.

  The seat being thus laid flat on the bed, the patient can be dragged so that it is properly positioned relative to the seat and the backrest, this operation is facilitated when the armrests are ergonomic and have a surface

  upper inclined outwards.

  The armrests 22 are then returned to their position perpendicular to the backrest and locked in this

  position which ensures a first maintenance of the patient.

  The backrest 21 is then brought back and locked in its position perpendicular to the seat 20, possibly with an intermediate blocking at approximately 60 '. This phase can be carried out using the tilting head of the bed if

she exists.

  At this instant, the patient is seated in the seat and supported by the back and the armrests with his legs still stretched out on his bed. A patient support belt on the seat can be put on if

8 2736821

  this one is not able to maintain itself adequately

by himself.

  The control means 3 is then used to lift the seat and move it away from the bed, then the chair is also moved away from the bed. The patient is thus seated in his chair while being turned to the right or to the left, it only remains to rotate the cushion 26 of the seat relative to the support plate to bring the seat in the position shown in Figure 1 for which the patient looks forward. A means not shown in the drawing ensures the blocking of the seat in the different

useful positions.

  An alternative embodiment of the present invention consists in allowing the separation of the support bracket 4, the support plate 23 and the

tips 31.

  This alternative embodiment allows a

  more flexible use of the chair according to the invention.

  The seat 2 can be detached from the chassis, which makes it easy to place it on the bed. The chair is then reassembled by fixing the end pieces 31 on the support bracket 4 after having mounted the latter on the plate.

support 23.

  The seat separated from the chassis can be used as a means of keeping the patient in a sitting position and

  be placed on a bed, a bench, a car seat.

  This variant embodiment of the chair according to the invention is the only way to install a patient in a vehicle without having to carry it in the arms

  and contort to make him pass the door.

  This variant also has the advantage of allowing the movement of several patients using a single frame on which the seat of a patient is fixed in turn. We can thus limit the need for equipment in retirement homes, hospitals, etc. The assembly ensuring the rotation of the cushion 26 of the seat relative to the support plate 23 is

9 2736821

  preference chosen to free up a large space

  central symbolized by the circle 25 in Figure 4.

  In this case, the support plate 23 is cut so as to have a wide opening in this central space while the seat 20 has removable portions allowing this central space to be freed. It is then possible to position a hygienic bucket under the seat or to position the chair above a bowl

by W.-C ..

  The particular arrangement of the base 10 allows, after rotating the seat cushion so that the patient is directed to the left of the chair, to position the seat above the toilet bowl in arranging the branches 13 and 14 of the base part and

else of this bowl.

  This possibility makes it possible to preserve the patient's privacy, which can be installed properly and safely.

security and left alone.

  Another advantage of the chair according to the invention is that it can be used to position the patient in front of a table, possibly positioning the armrests in the plane of the backrest so as not to impede movement

of the patient.

  The seat of the armchair according to the invention can be produced in different ways, more or less

comfortable.

  We can thus provide a seat for

  plastic to allow its use in the shower.

  A frame carrying legs can be supplied as an accessory to transform the mobile chair into a fixed chair. This frame is arranged and fixed to seat 2 and the chassis

1 is withdrawn.

  In known manner, it is possible to adapt to the chair according to the invention large wheels with hands

  to allow the patient to move around alone.

  It is also possible to adapt footrests. As will have been understood, the chair according to the invention allows very easy manipulation of a patient

2736821

  even seriously affected by everyone around him

  without requiring significant effort.
