DEVICE FOR LIFTING PEOPLE

  The subject of the invention is a device for lifting people capable of lifting people who are generally sick, disabled or injured.

on a bed or on a floor.

  We already know from the U.S.P. 4 195 375, a device for lifting a person lying on a bed comprising a base surmounted by

  a gantry fitted with two spaced beams able to be positioned above and parallel to the person, flexible straps fixed by one of their ends to one of the beams at spaced points are passed under the person and hung on the other beams to support the person.

  The installation of such flexible straps, in particular their passage under the body of the person is delicate and difficult and generally requires the intervention of two assistants, the first introducing the flexible straps on one side of the body of the person, and the second retrieving 15 the flexible straps on the other side of the person's body in order to hang them on the beam. In addition, such a device is not suitable for lifting a person lying in a bed which is not accessible by one

on his side.

  The main object of the invention is to achieve a device raises 20 people of simple and rapid implementation.

  Another object of the invention is to provide a device that is safe to use, notably avoiding any swaying of the person during transport.

  Another object of the invention is to result in a device making it possible to lift people lying down on the one hand in a bed positioned in a place with difficult access and on the other hand on a floor.

  In a lifting device comprising - a frame, - a beam suspended from the frame and contained in a horizontal plane at a given level intended to be positioned above parallel to a person lying in a plane substantially parallel to the horizontal plane, - at least a lifting means fixed to the beam and able to pass at least partially under said person,

  - Lifting means incorporated in the frame moving the lifting means along a vertical axis perpendicular to the horizontal plane, according to the invention the lifting means is at least one handling conveyor.

  Advantageously, the lifting means is a handling conveyor with a head provided with a hinge pin on which is articulated a vertical adjustment member with multiple positions or, two handling conveyors articulated by their respective heads around a common axis of articulation and arranged 5 in opposite directions to form a clamp Limited in its closing movement by a stop means.

  A device according to the invention has a frame in which are incorporated means for lifting the beam according to a vertical axis perpendicular to the horizontal plane containing the beam and passing through the beam and comprises in addition: - a U-shaped base contained in a substantially horizontal plane composed of two parallel side rails, spaced one. distance at least equal to the width of a person and, joined together by a cross member defining a free surface with the lateral beams, the vertical axis of movement of the beam passing at least through the free surface, - an upright bracket on the base fitted with an arm supporting the beam in the horizontal plane,

  - The arm comprising means for rotating the beam in the horizontal plane.

  We will now give without limiting intention and without excluding any variant, a description of a preferred embodiment. We will refer

  in the accompanying drawings in which: - Figure 1 is a general perspective view of a device according to the invention, - Figure 2 is a perspective view of a handling cé joined to a beam partially shown, - the Figure 3 is a front view of two handling Caes forming a clamp with a first connection mode, - Figure 4 is a view of a second connection mode of two handling Caes, Figure 5 is a view longitudinal section of the vertical adjustment member anchored to a beam, - Figure 6 is a schematic view in longitudinal section of the arm guide means in the bracket shown partially, - Figure 7 is a top view in cross section. the guide means passing through the axis of a set of rollers, FIG. 8 is a front view of the guide means disposed in the bracket,

  - Figure 9 is a perspective view of a means of rotation of the beam.

  The lifting device described by way of example and in accordance with FIG. 1 comprises a frame 1 supporting a beam 2 contained substantially in a horizontal plane H provided with removable lifting means 5 intended to pass at least partly under the body of a person to lift it. In a first embodiment, the lifting means is a handling block 3 (FIG. 2) and in a second embodiment, two handling blocks 3A, 3B arranged in opposite directions to form

pliers (Figure 3).

  A handling conveyor 3 is composed of a support piece such as a curved rigid blade 4 of small thickness extended by a rigid element 5 curved (C-shaped) and terminated by a head 6 provided with an axis of joint 7; for example, the rigid element 5 is a tube welded to the end E

blade 4.

  Of course, the configuration of a handling cé is directly determined by the morphology of the person to be lifted. Thus, the length of the blade defined between the end E and the free end E 'must be substantially equal to or preferably greater than the width of the part of the body in contact with the blade; for example, a handling cé positioned under the legs has a blade smaller than a handling cé blade placed under the back of a person. In addition, the blade is slightly curved in its main part 4E in order to conform as much as possible to the body of the person and has a width suitable for the part of the body in contact with the blade; moreover, this main part 4E towards its end E 'and up to this end E' is terminated by an end part 4E 'with a curvature more pronounced than the curvature of the main part in order to avoid any sliding

of the person.

  A vertical adjustment member 8, such as for example a hollow tube, preferably rigid, is articulated around the axis of articulation 7; this vertical adjustment member 8 carries successive holes 9A, 9B diametrically opposite and axes

  sensitive m ent parallel to the rigid m e 4.

  According to a second embodiment of the lifting means, the latter.

  is composed of two handling Ces 3A, 3B articulated by their respective heads 6A, 6B around an axis common to articulation 7 '; these two handling Caes 35 are arranged in opposite directions in order to form a clamp and are connected by a connecting element 10 to the vertical adjustment member 8

at a point of articulation 11.

Z 6 0 2 1 3 7

  -4 This connecting element 10 allows an amplitude of opening of the clamp which ensures the passage of the body of the person to be lifted between the blades 4A and 4B. In addition, during the lifting of a person, this connecting element 10 allows the handling Ces 3A, 3B to remain well closed under the action of the force exerted on the blades 4A, 4B. By way of example, and in a first variant, the connecting element 10 is produced by - a deformable parallelogram composed of two parts 12A, 12B respectively extending the handling Ces 3A, 3B beyond their common axis with articulation 7 ', and two links 13A, 13B articu10 linked on the one hand to one of their ends at the point of articulation 11 and on the other hand to the other of their end with the parts 12A, 12B around 'respective axes of articulations 14A, 14B; the links 13A, 13B could be replaced by an equivalent means such as for example a chain. The closing movement of the clamp is limited by a stop means 15 produced for example by two portions 15A, 15B of the rigid element of the respective handling Ces 3A, 3B which abut one against

the other before the blades 4A, 4B.

  In a second variant (FIG. 4), the part 12B carries an oblong hole 16 in which a shaft 17 is trapped with a suitable lateral clearance, and the part 12A is produced in a hook which comes in correspondence with

  the oblong hole 16 when the handling Ces are in the closed position, their locking being effected by vertically moving the vertical adjustment member 8 which brings the shaft 17 under the hook.

  The lifting means according to the first or second embodiment 25 provided with its vertical adjustment member 8 is removably attached to the beam 2 to a horizontal adjustment member 18 which advantageously moves in translation along the beam 2 without rotation; for example, the horizontal adjusting member 18 has a slightly square cross section

  greater than the cross section of beam 2 which is also square.

  This horizontal adjustment member 18 is provided with an anchoring means 19 (figure) such as a hook forming an ant hook which is capable of being introduced into one of the holes 9A, 9B produced on the adjustment member. vertical 8. Preferably, the horizontal adjustment member 18 also carries a locking means 20 such as a safety loop anchoring fixedly the lifting means to the beam 2. This beam 2 contained in a plane H and provided with the means lifting is suspended from the frame 1 which is composed of three parts; - 5 - Firstly: a U-shaped base 21 is made up of two lateral side members 22, 23 preferably of the telescopic type, spaced apart, parallel and joined by a cross-member 24; a free surface 25 is thus defined between the side rails 22, 23 and the cross-member 24. This base 21 includes 5 rolling means 25 so that it can easily be moved on a ground

  26, such as for example rollers disposed at each end of the side rails 22, 23. The base 21 defines a plane H 'substantially parallel on the one hand to the ground 26 on which the device lifts people must be when it is in use and on the other hand to the plane H containing the beam 2; these 10 planes H and H 'will be called horizontal planes thereafter.

  Secondly: a bracket 27 with a longitudinal axis 28 substantially perpendicular to the horizontal plane H 'and which will be designated hereinafter the vertical axis, is erected on the base 21 preferably in the middle of the crosspiece 24. This bracket 27 is produced for example by a rectangular rectangular hollow tube 15 which has a slot 29 which extends along the longitudinal axis 28 over the whole

the length of the stem.

  Third: an arm 30 of telescopic type has a front element 31 and a rear element 32 sliding in the front element 31. The latter supports the beam 2 and, the rear element 32 which passes through the slot 29 is fixed 20 to a guide means 33 sliding vertically inside the bracket.

  The vertical translational movement of the guide means 33 is given by lifting means 34 arranged on the bracket at an accessible level; these lifting means 34, irreversible, consists for example of an endless screw 35 controlled manually or electrically meshing 25 with a toothed wheel 36 mounted on a shaft 37 on which is fixed and can wind one end d 'a strap 38; this passes around a pulley 39 disposed at the upper end of the bracket 27 and has its other

  end fixed to the guide means 33.

  The latter, as shown by way of example in FIGS. 30 6 to 8, comprises a mobile carriage 40 taking place inside the bracket 27 and on which the rear element 32 of the arm 30 is fixed as well that

  connecting bar 41 connected to the rear element 32.

  The mobile carriage 40 comprises two sets of main rollers 42,43 mounted to rotate on respective axes 44,45, disposed respectively at the upper 46 and lower 47 part of the mobile carriage; each set of main rollers 42, 43 has two respective rollers 42A, 42B, and 43A, 43B arranged apart

and on the other side of the mobile carriage.

  -6 Preferably, the axes 44, 45 are offset transversely and symmetrically relative to the vertical axis 28 of the bracket 27 so that the rollers of the upper clearance 42 are only in contact with the inner wall 46 'of the front face of the stem and the rollers of the lower clearance 5 43 are in contact only with the internal wall 47 'of the rear face

of the gallows.

  In addition, between the two sets of main rollers 42, 43 is arranged on the one hand at the upper part 46 of the mobile carriage an axis 48 which carries two rollers 49A, 49B arranged on either side of the mobile carriage and in contact 10 with the internal wall 47 ′ of the rear face of the bracket and on the other hand at the lower part 47 of the mobile carriage an axis 50 which carries two rollers 51A, 51B arranged on either side of the mobile carriage and in contact with the internal wall 46 ′ of the front face of the bracket; this provision of

  rollers prevents the mobile carriage from tipping over.

  Also, three secondary rollers 52, 53, 54 mounted on respective axes

  , 56, 57 on the movable carriage 40 have like tread the sides 58, 59 delimiting the slot 29; more specifically, the two extreme secondary rollers 52, 54 are in contact with the side 58 and the intermediate secondary roller 53 is in contact with the side 59 in order to control the lateral play 20 of the arm.

  Advantageously, the front element 31 of the arm 30 is equipped with a means 60 for rotating the beam 2 in the horizontal plane H. With reference to FIG. 9, the front element 31 carries a sheath 61 of vertical axis V inside which is rotatably mounted a shaft 62 connected by one end 63 to another sleeve 64 of horizontal axis containing a secondary beam 64 'free in rotation supporting the beam 2; the other end 65 of the shaft 62 is linked in rotation by a pin 66 to an outer sleeve 67 coaxial with the shaft 62. This sleeve 67 is supported on a flange 68 which is part of the front element 31 and which is provided with notches 69. A finger 70 secured to a rotating pin 71 mounted on the sleeve 67 is maneuvered by a lever 72; the

  finger 70 is able to be introduced into one of the notches 69 thus fixing the beam 2 in a given angular position. The secondary beam 64 'is connected.

  to the beam 2 by two force sensors 73, 74 spaced apart; their indications are taken into account in order to know the weight of the person lifted who is important to know for the treatment of burned people.

  The device according to the invention as described above is used in the following manner: when it is desired to lift or transport a person

2602 137

-7

  lying for example on a bed, the blade of the handling blade is engaged between the bed and the person by pressing on it; the rigid blade resting against the bed, which generally has a certain flexibility, sinks slightly into it and thus passes easily under the body of the person without causing discomfort for the latter. Preferably, a reduced thickness will be given to the blade to facilitate its passage under the body of the person.

  We thus pass several Cés of handling, for example six, under the person in suitable spaced places. It will be noted that in order to ensure a safe lifting of the person without risk of slipping notably due to his agitation, the lifting means composed only of a handling conveyor can be arranged alternately successively on either side

of the person.

  The handling caes being in place, the beam 2 is brought above the person at the level of the vertical adjustment member 8 using the lifting means 15. A horizontal adjustment member 18 is matched with each vertical adjustment member 8 then, these are hooked to the locking means 20; we finally lift thanks to the lifting means

  34 the person who can thus be transported using the frame 1.

  The latter also makes it possible to take a person lying on the ground while having a reduced bulk. For such an operation, the distance between the side members 22, 23 of the base m I must be taken at least between the width and the height of a person. Advantageously for reasons of space, the spacing between the side members is substantially greater than the width of the body of the person so that the side members are positioned on each side of the person. In order to be able to position

  the beam 2 parallel to the top of the person using the rotation means 60, the telescopic arm 30 is extended as well as the side beams 22, 23 telescopic so that the trace of the vertical axis V on the plane - H ' is always contained within the free surface 25 to ensure the stability of the device.
