Description

LIT MUNI D'UN RELEVE-DOS BED WITH A BACK-UP
La présente invention concerne un lit, par exemple un lit d'hôpital, muni d'un relève-dos susceptible de pivoter entre une position horizontale et une série de positions inclinées, de façon à amener le patient se trouvant dans ce lit, d'un état couché à un état relevé, voire même sensiblement assis. Ce relève-dos supporte le dos et la tête du patient et correspond environ au 2/5 de la longueur de couchage du lit.The present invention relates to a bed, for example a hospital bed, provided with a backrest capable of pivoting between a horizontal position and a series of inclined positions, so as to bring the patient in this bed, from a lying state to a raised state, or even substantially seated. This backrest supports the patient's back and head and corresponds to approximately 2/5 of the bed's length.
Afin d'améliorer le confort du patient et de diminuer la sensation de compression sur l'abdomen lorsque le relève-dos est incliné, celui-ci est généralement muni de moyens lui permettant de coulisser simultanément en direction de la tête du lit.In order to improve the comfort of the patient and reduce the feeling of compression on the abdomen when the backrest is tilted, it is generally provided with means allowing it to slide simultaneously in the direction of the head of the bed.
On connaît ainsi d'après le document FR-2 770 397, un lit équipé d'un relève-buste manœuvré par un actionneur et monté sur un châssis, de façon à effectuer un mouvement de translation en direction de la tête du lit, lors de son levage. Ce relève-buste est en outre muni de deux bielles. La première bielle est articulée sur le châssis, (au voisinage de la tête de lit) et au milieu du relève- buste. La deuxième bielle est articulée à la base du relève-buste et sur le châssis, sensiblement à l'aplomb du bassin de l'utilisateur. L'inclinaison du relève-buste en direction de la verticale entraîne un déplacement simultané de celui-ci vers la tête du lit.Document FR-2 770 397 thus discloses a bed equipped with a backrest operated by an actuator and mounted on a frame, so as to effect a translational movement in the direction of the head of the bed, during of its lifting. This backrest is also provided with two connecting rods. The first connecting rod is articulated on the chassis (near the headboard) and in the middle of the backrest. The second connecting rod is articulated at the base of the backrest and on the chassis, substantially perpendicular to the user's pelvis. The inclination of the backrest in the vertical direction causes it to move simultaneously towards the head of the bed.
On connaît également d'après le document WO-97/05 803, une table d'examen ou lit facilitant le passage d'un patient de la position couchée, à la position debout.Also known from document WO-97/05 803, an examination table or bed facilitating the passage of a patient from the lying position to the standing position.
Cette table d'examen présente des pieds, un châssis articulé et un matelas rigide présentant une section de buste, une section de siège et une section de pieds.This examination table has legs, an articulated frame and a rigid mattress having a bust section, a seat section and a leg section.
Le châssis articulé soutenant le matelas rigide peut occuper une première position dans laquelle les trois sections du matelas sont horizontales et une deuxième position dans laquelle les sections de buste et de pieds de ce matelas sont sensiblement verticales, de façon que cette table d'examen se transforme en chaise.The articulated frame supporting the rigid mattress can occupy a first position in which the three sections of the mattress are horizontal and a second position in which the bust and foot sections of this mattress are substantially vertical, so that this examination table is transforms into a chair.
Lorsque la section de buste du matelas est amenée en position chaise, elle peut coulisser simultanément par rapport aux longerons du châssis, en direction de la tête de cette table d'examen. Toutefois la structure de ce dispositif est extrêmement complexe. La présente invention a pour but de mettre au point un lit tel que précité, d'une structure et d'un fonctionnement simples et qui permette de diminuer considérablement la pression exercée par le relève-dos, sur le dos et l'abdomen du patient utilisant ce lit, lorsque ce relève-dos est redressé.When the bust section of the mattress is brought into the chair position, it can slide simultaneously with respect to the frame rails, in the direction of the head of this examination table. However, the structure of this device is extremely complex. The present invention aims to develop a bed as above, of a simple structure and operation and which allows to significantly reduce the pressure exerted by the backrest, on the back and abdomen of the patient using this bed, when this backrest is straightened.
Ce but est atteint à l'aide d'un lit, notamment d'hôpital, comprenant un châssis surmonté d'un plan de couchage, ce châssis ayant une partie fixe sensiblement horizontale et une partie inclinable susceptible de pivoter, sous l'action de moyens de réglage de son inclinaison, autour d'un premier axe horizontal, perpendiculaire à la direction longitudinale dudit lit, ledit plan de couchage comprenant au moins un plan formant relève-dos, guidé en translation par rapport à ladite partie inclinable du châssis, de façon à pouvoir coulisser en direction de la tête du lit ou dans la direction opposée, respectivement lors du relèvement ou de l'abaissement de ladite partie inclinable du châssis.

Comme illustré sur la figure 1, le lit comprend un châssis 1 surmonté d'un plan de couchage 2, destiné à recevoir un matelas non représenté sur la figure. Ce châssis constitue la structure de base du lit. Il est destiné à être monté sur des pieds non représentés sur la figure. Le plan de couchage 2 se compose de quatre parties, à savoir successivement de la tête au pied du lit, d'un relève-dos 20, d'une partie formant support du bassin 21, d'un plan support des cuisses 22 et d'un plan support des piedsAs illustrated in Figure 1, the bed comprises a frame 1 surmounted by a sleeping surface 2, intended to receive a mattress not shown in the figure. This frame constitutes the basic structure of the bed. It is intended to be mounted on feet not shown in the figure. The sleeping surface 2 consists of four parts, namely successively from head to foot of the bed, a back rest 20, a part forming a support for the pelvis 21, a support plane for the thighs 22 and d '' foot support plan
23, ces deux derniers plans pouvant être d'une seule pièce, dénommée de façon générale "plan support des jambes".23, these last two planes can be in one piece, generally called "leg support plane".
Le relève-dos 20 est les plans support des cuisses 22 et des pieds 23 sont constitués par des panneaux rigides, réalisés de préférence en matière plastique, afin de faciliter leur nettoyage et leur désinfection.The backrest 20 is the support surfaces of the thighs 22 and the feet 23 are formed by rigid panels, preferably made of plastic, in order to facilitate their cleaning and disinfection.
La partie formant support de bassin 21 peut être souple et déformable ou au contraire rigide et fixée sur le châssis 1.The part forming the basin support 21 can be flexible and deformable or, on the contrary, rigid and fixed to the chassis 1.
Lorsqu'elle est souple, elle peut être réalisée en matière plastique d'un seul morceau ou être constituée de plusieurs lattes jointives comme illustré sur la figure 3. Son bord transversal 210 situé du côté de la tête du lit est solidaire du bord transversal du relève-dos 20 comme cela sera décrit plus en détail ci-après. Son bord transversal opposé 211 est mince et repose simplement sur une partie du plan support des cuisses 22.When it is flexible, it can be made of plastic in one piece or be made up of several contiguous slats as illustrated in FIG. 3. Its transverse edge 210 located on the side of the head of the bed is integral with the transverse edge of the back 20 as will be described in more detail below. Its opposite transverse edge 211 is thin and simply rests on a part of the thigh support plane 22.
Lorsqu'elle est rigide, elle est réalisée dans la même matière plastique que les autres parties du plan de couchage 2.When it is rigid, it is made of the same plastic material as the other parts of the sleeping surface 2.
Comme on peut le voir sur les figures 1 ou 2, le relève-dos 20 présente une face supérieure 200 destinée à recevoir un matelas, une face opposée dite "face inférieure" 201 et un bord transversal 202 jouxtant le bord transversal 210 du support de bassin 21 et fixé à celui-ci, par exemple par collage.As can be seen in Figures 1 or 2, the backrest 20 has an upper face 200 for receiving a mattress, an opposite face called "lower face" 201 and a transverse edge 202 adjoining the transverse edge 210 of the support basin 21 and fixed thereto, for example by gluing.
Comme illustré sur la figure 2, le châssis 1 comprend une partie fixe 10 sensiblement horizontale une partie inclinable 11. La partie fixe 10 constitue la structure de base du lit et comprend notamment deux profilés longitudinaux 100, 100' parallèles, reliés entre eux par une série de traverses dont la traverse 101 horizontale. Cette traverse 101 s'étend perpendiculairement à la direction longitudinale du lit, symbolisée par l'axe longitudinal médian X-X' de ce lit. Elle est positionnée sensiblement à l'aplomb de la taille du patient couché dans le lit.As illustrated in FIG. 2, the chassis 1 comprises a fixed part 10 which is substantially horizontal, a tilting part 11. The fixed part 10 constitutes the basic structure of the bed and in particular comprises two parallel longitudinal sections 100, 100 ′, connected together by a series of sleepers including horizontal 101. This cross member 101 extends perpendicular to the longitudinal direction of the bed, symbolized by the median longitudinal axis XX ′ of this bed.

Ils sont reliés entre eux transversalement par une traverse 111 située vers la tête du lit et sont soudés à leurs extrémités opposées à un axe transversal 112, parallèle à ladite traverse 101. Cet axe 112 est disposé entre la traverse 101 et le pied du lit, sensiblement à l'aplomb des fesses du patient. Il est susceptible de se déplacer par translation latérale, sensiblement horizontalement et perpendiculairement à la direction longitudinale X-X' du lit. A cet effet, chaque extrémité de l'axe 112 est reçue dans un profilé enThe tilting part 11 of the chassis comprises at least one, and preferably two, longitudinal beams 110, 110 ', parallel to each other, preferably extending on either side of the median longitudinal axis XX' of the bed. They are interconnected transversely by a cross member 111 situated towards the head of the bed and are welded at their ends opposite to a transverse axis 112, parallel to said cross member 101. This axis 112 is disposed between the cross member 101 and the foot of the bed, substantially in line with the patient's buttocks. It is capable of moving by lateral translation, substantially horizontally and perpendicular to the longitudinal direction XX 'of the bed. For this purpose, each end of the axis 112 is received in a profile in
"C" 102, respectivement 102', ouvert en direction de l'intérieur du lit, et monté respectivement sur chaque profilé 100, 100' du châssis."C" 102, respectively 102 ', open towards the interior of the bed, and mounted respectively on each profile 100, 100' of the frame.
Ces profilés en "C" 102, 102' ont pour fonction d'assurer le guidage de l'axe 112 lors de son déplacement en translation latérale. Le lit selon l'invention comprend en outre, des moyens de réglage 3 de l'inclinaison de la partie inclinable 11 du châssis. Ces moyens de réglage 3 comprennent un vérin hydraulique 30 s'étendant longitudinalement sous le lit et une biellette 31. Celle-ci est montée pivotante autour d'un axe 32 traversant l'extrémité de la tige du vérin hydraulique 30 et elle est soudée sur l'axe 112. Selon une première variante de réalisation de l'invention non illustrée sur les figures, les longerons longitudinaux 110, 110' pourraient être articulés autour de l'axe transversal 112 au lieu d'y être soudés.These “C” sections 102, 102 ′ have the function of guiding the axis 112 during its movement in lateral translation. The bed according to the invention further comprises means 3 for adjusting the inclination of the tilting part 11 of the chassis. These adjustment means 3 comprise a hydraulic cylinder 30 extending longitudinally under the bed and a link 31. The latter is pivotally mounted about an axis 32 passing through the end of the rod of the hydraulic cylinder 30 and it is welded to the axis 112. According to a first alternative embodiment of the invention not illustrated in the figures, the longitudinal beams 110, 110 ′ could be articulated around the transverse axis 112 instead of being welded to it.
Selon une deuxième variante de réalisation, également non représentée sur les figures, l'axe 112 soutenant les longerons 110, 110' pourrait être fixe et jouerait alors le rôle d'une traverse et c'est la travese 101 qui serait mobile en translation à l'intérieur de profilés en "C" et qui jouerait le rôle d'axe mobile .According to a second alternative embodiment, also not shown in the figures, the axis 112 supporting the longitudinal members 110, 110 ′ could be fixed and then play the role of a cross member and it is the cross member 101 which would be movable in translation at the interior of "C" sections which would act as a movable axis.
Le lit comprend en outre deux biellettes identiques 4, respectivement 4', permettant le déplacement en translation du relève-dos 20 par rapport à la partie inclinable 11 du châssis. La biellette 4' porte les mêmes références que la biellette 4 majorées du signe '.The bed also comprises two identical links 4, 4 ′ respectively, allowing the backrest 20 to move in translation relative to the tilting part 11 of the frame. The link 4 'has the same references as the link 4 plus the sign'.
Comme illustré sur la figure 2, la biellette 4' présente une extrémité 40', dite "extrémité de liaison", montée pivotante autour de la traverse 101 grâce à une bague de rotation 400'.As illustrated in FIG. 2, the link 4 ′ has an end 40 ′, called the “connection end”, pivotally mounted around the cross member 101 by means of a rotation ring 400 ′.
Comme cela apparaît mieux sur la vue de détail de la figure 4, l'extrémité opposée 41 de ladite biellette 4, dite "extrémité de déplacement" est montée pivotante autour d'un axe ou d'une goupille 42 traversant le longeron longitudinal 110 et s'étendant parallèlement à la traverse 101. Cet axe 42 est situé entre les deux extrémités opposées du longeron 110.As appears better on the detail view of FIG. 4, the opposite end 41 of said link 4, called "displacement end" is pivotally mounted around an axis or a pin 42 passing through the longitudinal beam 110 and extending parallel to the cross member 101. This axis 42 is located between the two opposite ends of the spar 110.
L'extrémité de déplacement 41 de la biellette 4 est recouvert d'un embout amovible 43 présentant une série de dents d'engrenage 44. Cet embout est avantageusement réalisé en matière plastique, tandis que les autres parties du châssis sont métalliques. Il est ainsi interchangeable en cas d'usure des dents 44.The displacement end 41 of the connecting rod 4 is covered with a removable end piece 43 having a series of gear teeth 44. This end piece is advantageously made of plastic, while the other parts of the chassis are metallic. It is thus interchangeable in the event of wear of the teeth 44.
Les dents 44 s'étendent radialement sur au moins une partie de la périphérie de l'extrémité de l'embout 43, selon un plan vertical. Elles sont susceptibles d'engrener avec une série d'orifices 203 prévues sur la face inférieure 201 du relève-dos 20. Ces orifices 203 sont avantageusement des orifices borgnes, de façon à ne pas déboucher sur la face supérieure 200 du relève-dos 20. Ces orifices 203 sont espacés régulièrement sur une ligne s'étendant selon la direction longitudinale X-X' du lit. Selon une variante de réalisation simplifiée, non représentée sur les figures, l'embout 43 n'existe pas et c'est l'extrémité de déplacement 41 de la biellette 4 qui porte directement les dents d'engrenage 4.The teeth 44 extend radially over at least part of the periphery of the end of the end piece 43, in a vertical plane. They are capable of meshing with a series of orifices 203 provided on the lower face 201 of the backrest 20. These orifices 203 are advantageously blind orifices, so as not to lead to the upper face 200 of the backrest 20 These orifices 203 are regularly spaced on a line extending in the longitudinal direction XX 'of the bed. According to a simplified variant embodiment, not shown in the figures, the end piece 43 does not exist and it is the displacement end 41 of the connecting rod 4 which directly carries the gear teeth 4.
Enfin, le lit comprend des moyens de guidage 5, respectivement 5', du relève-dos 20 lors de son mouvement de coulissement par rapport à la partie inclinable 11 du châssis.Finally, the bed comprises guide means 5, respectively 5 ′, of the backrest 20 during its sliding movement relative to the tilting part 11 of the chassis.
Ces moyens de guidage 5, 5' apparaissent mieux sur les vues de détail des figures 5 et 6.These guide means 5, 5 ′ appear better on the detailed views of FIGS. 5 and 6.
Comme illustré sur la figure 5, les moyens de guidage 5' comprennent un doigt de guidage 50' susceptible de coulisser à l'intérieur d'un orifice oblong 51'. Plus précisément, le doigt de guidage 50' traverse le longeronAs illustrated in FIG. 5, the guide means 5 'comprise a guide finger 50' capable of sliding inside an oblong orifice 51 '. More specifically, the guide finger 50 'crosses the beam
110' de part en part (voir figure 6), pour faire saillie sur sa face latérale 1100' orientée vers l'intérieur du lit. Il s'étend parallèlement à l'axe 42.110 'right through (see Figure 6), to protrude on its side 1100' facing the inside of the bed. It extends parallel to the axis 42.
L'orifice oblong 51' est ménagé en regard dudit doigt 50', à l'intérieur d'un élément 52' rapporté sur la face inférieure 201 du relève-dos 20 et faisant saillie depuis celui-ci. Plus précisément, cet élément 52' présente une section verticale en "C" dont l'ouverture est orientée vers ladite face inférieure 201. L'orifice oblong 51' se trouve délimité par cet élément en "C" 52' et la face inférieure 201 du relève-dos.The oblong orifice 51 ′ is formed opposite said finger 50 ′, inside an element 52 ′ attached to the underside 201 of the backrest 20 and protruding therefrom. More specifically, this element 52 'has a vertical section in "C" whose opening is oriented towards said lower face 201. The oblong orifice 51' is delimited by this element in "C" 52 'and the lower face 201 backrest.
D'autres dispositifs de guidage fonctionnant sur le même principe d'un doigt de guidage coopérant avec un orifice oblong pourraient également être prévus, le doigt de guidage étant prévu sur la face du longeron 110, 110' en regard du relève-dos et l'orifice l'oblong étant prévu sur la face inférieure 201 du relève- dos 20 ou inversement.Other guide devices operating on the same principle of a guide finger cooperating with an oblong orifice could also be provided, the guide finger being provided on the face of the beam 110, 110 'facing the backrest and the orifice the oblong being provided on the underside 201 of the backrest 20 or vice versa.
Le fonctionnement du lit va maintenant être décrit en faisant référence aux figures 2 et 3. Dans la position de départ ou position couchée, le relève-dos 20 et la partie inclinable 11 du châssis sont sensiblement horizontaux.The operation of the bed will now be described with reference to Figures 2 and 3. In the starting position or lying position, the backrest 20 and the tilting part 11 of the chassis are substantially horizontal.
L'actionnement du vérin hydraulique 30 entraîne le déplacement de la tige du piston dans la direction de la tête du lit, ce qui a pour effet d'entraîner le déplacement de la biellette 31 dans cette même direction.The actuation of the hydraulic cylinder 30 causes the displacement of the piston rod in the direction of the head of the bed, which has the effect of causing the displacement of the rod 31 in this same direction.
L'axe 112 de la partie inclinable 11 du châssis se déplace également en translation latérale, à l'intérieur des profilés 102, 102', en direction de la tête du lit. Ce déplacement, combiné à la présence des biellettes 4, 4 entraîne le relèvement progressif de la partie inclinable 11 du châssis. La partie inclinable 11 du châssis peut ainsi se relever jusqu'à un angle d'inclinaison d'environ 70° par rapport à l'horizontale. Toutes les positions intermédiaires sont également possibles. Une seule est représentée sur la figure 3 (inclinaison d'environ 35°).The axis 112 of the tilting part 11 of the chassis also moves in lateral translation, inside the profiles 102, 102 ', in the direction of the head of the bed. This movement, combined with the presence of the rods 4, 4 causes the tilting part 11 of the chassis to be gradually raised. The tilting part 11 of the chassis can thus be raised up to an angle of inclination of about 70 ° relative to the horizontal. All intermediate positions are also possible. Only one is shown in Figure 3 (inclination of approximately 35 °).
De façon simultanée, le pivotement angulaire de la biellette 4 entraîne le déplacement des dents d'engrenage 44 selon un arc de cercle. Ces dents engrènent avec les orifices 203 du relève-dos 20, ce qui a pour effet de faire coulisser le relève-dos 20 en direction de la tête du lit (flèches F).Simultaneously, the angular pivoting of the link 4 causes the gear teeth 44 to move in an arc of a circle. These teeth mesh with the orifices 203 of the backrest 20, which has the effect of causing the backrest 20 to slide in the direction of the head of the bed (arrows F).
Lorsque le support de bassin 21 est souple et solidaire du relève-dos 20, il suit le mouvement et se déplace également vers la tête de lit (flèche Fi). Le fait que le support de bassin 21 soit souple lui permet de se déformer et d'adopter la courbure souhaitée. Le bord transversal 211 glisse sur le plan support des cuisses 22. Ce bord est mince de façon à pouvoir glisser facilement entre un matelas et ce plan support 22.When the basin support 21 is flexible and integral with the backrest 20, it follows the movement and also moves towards the headboard (arrow Fi). The fact that the basin support 21 is flexible allows it to deform and adopt the desired curvature. The transverse edge 211 slides on the thigh support plane 22. This edge is thin so that it can slide easily between a mattress and this support plane 22.
Inversement le mouvement de pivotement de la partie 11 du châssis en direction de l'horizontale ramène le relève-dos 20 dans la direction opposée, c'est-à-dire vers le pied du lit. Conversely, the pivoting movement of the part 11 of the chassis in the direction of the horizontal brings the backrest 20 in the opposite direction, that is to say towards the foot of the bed.
