Description

L'invention a trait au domaine des lits médicalisés, destinés notamment au milieu hospitalier ou clinique, aux maisons médicalisées (typiquement les maisons de retraite), ou encore aux logements de patients recevant des soins à domicile.The invention relates to the field of hospital beds, intended in particular for hospitals or clinics, nursing homes (typically retirement homes), or homes for patients receiving home care.

Un lit médicalisé a notamment la particularité d'être équipé d'un cadre (portant le sommier et définissant un côté tête et un côté pied, généralement dissymétriques) réglable en hauteur, afin de faciliter les transferts du patient par le personnel médical et, lorsque le patient bénéficie d'une certaine autonomie, les opérations du coucher et du lever.A particular medical bed has the particularity of being equipped with a frame (carrying the bed base and defining a head and foot side, generally asymmetrical) adjustable in height, to facilitate the transfer of the patient by the medical staff and, when the patient enjoys a certain autonomy, the operations of bedtime and sunrise.

A cet effet, le lit intègre un dispositif de réglage du cadre en hauteur, comprenant un (ou plusieurs) mécanisme(s) couplé(s) à une (ou plusieurs) motorisation(s) qui peut (peuvent) être pilotée(s) via une télécommande par le patient ou par le personnel médical.For this purpose, the bed incorporates a device for adjusting the height frame, comprising one (or more) mechanism (s) coupled (s) to one (or more) motor (s) that can (can) be controlled (s) via a remote control by the patient or by the medical staff.

On connaît divers types de mécanismes. Citons par exemple les mécanismes à croisillon, cf. par ex. la demande de brevet français FR 2 990 620 ou son équivalent européen EP 2 666 449 (Médicatlantic), ou encore les mécanismes à compas, cf. par ex. le brevet américain US 7 013 510 (Raye's ) ou la demande de brevet français FR 2 769 832 (Sunrise Medical).Various types of mechanisms are known. For example, the cross mechanisms, cf. eg. the French patent application FR 2,990,620 or its European equivalent EP 2 666 449 (Médicatlantic), or else the mechanisms with compasses, cf. eg. the US patent US 7,013,510 (Raye's ) or the French patent application FR 2,769,832 (Sunrise Medical).

Quel que soit le type de mécanisme employé, il doit généralement permettre, outre le simple réglage en hauteur, d'offrir des fonctions d'inclinaison, respectivement proclive (dans laquelle le cadre est incliné de manière que le côté tête soit plus élevé que le côté pied, afin de permettre l'écoulement des fluides pathologiques) et déclive (dans laquelle le cadre est incliné de manière que le côté pied soit plus élevé que le côté tête, cette fonction étant requise en cas d'urgence lorsque le pronostic vital est engagé et nécessite d'irriguer le cerveau dans l'instant).Whatever the type of mechanism employed, it must generally allow, in addition to simple height adjustment, to offer tilting functions, respectively proclive (in which the frame is inclined so that the head side is higher than the foot-side, to allow the flow of pathological fluids) and sloping (in which the frame is inclined so that the foot side is higher than the head side, this function being required in case of emergency when life-threatening is committed and requires to irrigate the brain in the moment).

Afin de permettre ces fonctions, les mécanismes à croisillon sont généralement doublés de mécanismes supplémentaires situés en tête et, respectivement, au pied de lit, et pouvant être commandés par le personnel médical en cas de besoin.In order to enable these functions, the cross mechanisms are usually doubled with additional mechanisms located at the head and respectively at the foot of the bed, and can be controlled by the medical staff when needed.

Les mécanismes à compas sont structurellement plus simples (et donc plus légers) que les lits à croisillon, car ils comprennent un compas de tête et un compas de pied qui peuvent être pilotés en synchronisme pour le réglage simple en hauteur, ou de manière séparée pour les fonctions proclive ou déclive.The compass mechanisms are structurally simpler (and therefore lighter) than the spider beds because they include a head compass and a foot compass that can be controlled in synchronism for simple height adjustment, or separately for the functions proclive or declive.

La demande de brevet français FR 2 769 832 précité propose ainsi un lit médicalisé comprenant :

  • un sommier muni de longerons et de traverses et ayant un côté tête et un côté pied opposés ;
  • un dispositif de réglage en hauteur du sommier par rapport au sol, ce dispositif comprenant un compas de tête monté sur le sommier du côté tête, et un compas de pied monté sur le sommier du côté pied, chaque compas comprenant une branche et une biellette articulées mutuellement et par rapport au sommier, chaque compas ayant une position repliée dans laquelle la branche jouxte le sommier, et une position déployée dans laquelle la branche est écartée du sommier ;
  • un train avant comprenant une traverse fixée à la branche du compas de tête, cette traverse portant à chacune de ses deux extrémités une paire de roulettes orientables ;
  • un train arrière comprenant une traverse fixée à la branche du compas de pied, cette traverse portant à chacune de ses deux extrémités une paire de roulettes orientables.
The French patent application FR 2,769,832 aforementioned proposes a medical bed comprising:
  • a box spring with longitudinal members and cross members and having an opposing head and foot side;
  • a device for adjusting the height of the bed base with respect to the ground, this device comprising a head compass mounted on the bed base of the head side, and a foot compass mounted on the bed base on the foot side, each compass comprising a hinged arm and a link mutually and in relation to the bed base, each compass having a folded position in which the branch adjoins the bed base, and an extended position in which the branch is spaced from the bed base;
  • a front train comprising a cross member fixed to the branch of the head compass, this cross carrying at each of its two ends a pair of steerable wheels;
  • a rear train comprising a cross member attached to the leg of the leg, this cross carrying at each of its two ends a pair of steerable wheels.

Le brevet américain US 7 013 510 précité propose ainsi un lit médicalisé comprenant :

  • un cadre muni de longerons et de traverses et ayant un côté tête et un côté pied opposés ;
  • un dispositif de réglage en hauteur du cadre par rapport au sol, ce dispositif comprenant un compas de tête monté sur le cadre du côté tête, et un compas de pied monté sur le cadre du côté pied, chaque compas comprenant une jambe et une bielle (en l'espèce sous forme d'un vérin) articulées mutuellement et par rapport au cadre, chaque compas ayant une position repliée dans laquelle la jambe jouxte le cadre, et une position déployée dans laquelle la jambe est écartée du cadre ;
  • un train avant comprenant un galet monté en rotation par rapport à la jambe du compas de tête, à une extrémité inférieure de celui-ci, autour d'un axe transversal ;
  • un train arrière comprenant un chariot de pied articulé par rapport à la jambe du compas de pied à une extrémité inférieure de celle-ci, et une roue arrière folle montée en libre rotation sur le chariot de pied.
The US patent US 7,013,510 aforementioned proposes a medical bed comprising:
  • a frame with side members and cross members and having opposite head and side feet;
  • a device for adjusting the height of the frame with respect to the ground, this device comprising a head compass mounted on the frame of the head side, and a foot compass mounted on the frame on the foot side, each compass comprising a leg and a connecting rod ( in this case in the form of a jack) articulated mutually and with respect to the frame, each compass having a folded position in which the leg adjoins the frame, and an extended position in which the leg is spaced from the frame;
  • a nose gear comprising a roller rotatably mounted relative to the leg of the head compass, at a lower end thereof, about a transverse axis;
  • a rear axle comprising a foot carriage articulated with respect to the leg of the foot compass at a lower end thereof, and a crazy rear wheel mounted for free rotation on the foot carriage.

Ce lit possède une position basse, dans laquelle les compas sont repliés, et une position élevée (destinée aux soins), dans laquelle les compas sont déployés et chaque galet en contact avec le sol.This bed has a low position, in which the compasses are folded, and a high position (for care), in which the compasses are deployed and each roller in contact with the ground.

Les roues folles du train arrière permettent, côté pied, des mouvements tant longitudinaux (dans la direction définie par les longerons) que transversaux (dans la direction définie par les traverses). Les galets du train avant ne permettent en revanche, côté tête, que les mouvements longitudinaux (nécessaires aux réglages en hauteur du lit, ainsi qu'à la mise en positions proclive et déclive). Cette limitation des mouvements côté tête présente l'avantage d'éviter les dérobades transversales du lit lors du coucher ou du lever du patient tout en permettant les petits mouvements longitudinaux de réglage de la proximité du lit avec un mur attenant, mais elle présente cependant l'inconvénient de rendre délicates les grandes manoeuvres du lit (par exemple lors d'un transfert du lit, avec ou sans patient).The idler wheels of the rear train allow, on the foot side, movements both longitudinal (in the direction defined by the longitudinal members) and transversal (in the direction defined by the sleepers). On the other hand, the rollers of the front axle only allow, on the side of the head, only the longitudinal movements (necessary for the adjustments in height of the bed, as well as for the positioning in proclive and declivel positions). This limitation of the movements on the head side has the advantage of avoiding transverse evasions of the bed during the bedtime or the rising of the patient while allowing the small longitudinal movements of adjustment of the proximity of the bed with an adjoining wall, but it nevertheless presents the disadvantage of making delicate the large maneuvers of the bed (for example during a transfer of the bed, with or without patient).

Un premier objectif est par conséquent de proposer un lit médicalisé du type à compas, permettant, dans certaines conditions, de permettre ou d'interdire les mouvements transversaux du lit côté tête.A first objective is therefore to provide a medical bed of the compass type, allowing, under certain conditions, to allow or prohibit transverse movements of the bed side head.

Un deuxième objectif est de permettre ou d'interdire les mouvements transversaux du lit côté tête, en fonction de la position du cadre.A second objective is to allow or prohibit transverse movements of the bed side head, depending on the position of the frame.

Un troisième objectif est de libérer les mouvements transversaux de manière automatique, en fonction de la position du cadre.A third objective is to release the transverse movements automatically, depending on the position of the frame.

A cet effet, il est proposé un lit médicalisé comprenant :

  • un cadre muni de longerons et de traverses et ayant un côté tête et un côté pied opposés ;
  • un dispositif de réglage en hauteur du cadre par rapport au sol, ce dispositif comprenant un compas de tête monté sur le cadre du côté tête, et un compas de pied monté sur le cadre du côté pied, chaque compas comprenant une jambe et une bielle articulées mutuellement et par rapport au cadre, chaque compas ayant une position repliée dans laquelle la jambe jouxte le cadre, et une position déployée dans laquelle la jambe est écartée du cadre ;
  • un train avant comprenant au moins un galet monté en rotation par rapport à la jambe du compas de tête, à une extrémité inférieure de celui-ci, uniquement autour d'un axe transversal ;
  • un train arrière comprenant un chariot de pied articulé par rapport à la jambe du compas de pied à une extrémité inférieure de celle-ci, et au moins une roue arrière folle montée en libre rotation sur le chariot de pied ;
ce lit ayant une position basse dans laquelle les compas sont repliés et une position élevée dans laquelle les compas sont déployés et chaque galet en contact avec le sol, lit dans lequel :
  • le train avant comprend un chariot de tête articulé par rapport à la jambe du compas de tête autour d'un pivot transversal et sur lequel est monté le galet, et au moins une roue avant folle montée en rotation sur le chariot de tête autour d'un axe de roulage et d'un axe de lacet, le chariot de tête portant une butée agencée pour interagir avec la jambe du compas de tête ;
  • le lit possède une position surélevée dans laquelle les compas sont déployés jusqu'en fin de course, et dans laquelle la jambe du compas de tête place, par interaction avec la butée, le chariot de tête dans une position basculée dans laquelle le galet est écarté du sol et dans laquelle l'axe de lacet de la roue avant est sensiblement perpendiculaire au sol.
For this purpose, it is proposed a medical bed comprising:
  • a frame with side members and cross members and having opposite head and side feet;
  • a device for adjusting the height of the frame with respect to the ground, this device comprising a head compass mounted on the frame on the head side, and a foot compass mounted on the frame on the foot side, each compass comprising a leg and a connecting rod mutually articulated and relative to the frame, each compass having a folded position in which the leg adjoins the frame, and an extended position in which the leg is spaced from the frame;
  • a nose gear comprising at least one roller rotatably mounted relative to the leg of the head compass, at a lower end thereof, only about a transverse axis;
  • a rear axle comprising a foot carriage articulated with respect to the leg of the foot compass at a lower end thereof, and at least one idle rear wheel mounted for free rotation on the foot carriage;
this bed having a low position in which the compasses are folded and an elevated position in which the compasses are deployed and each roller in contact with the ground, reads in which:
  • the front axle comprises a head carriage articulated with respect to the leg of the head compass around a transverse pivot and on which the roller is mounted, and at least one idle front wheel rotatably mounted on the head carriage around a rolling axis and a yaw axis, the head carriage carrying a stop arranged to interact with the leg of the head compass;
  • the bed has an elevated position in which the compasses are deployed to the end of the stroke, and in which the leg of the head compass places, by interaction with the stop, the head carriage in a tilted position in which the roller is removed of the ground and wherein the yaw axis of the front wheel is substantially perpendicular to the ground.

Ainsi, grâce à la butée actionnée par la jambe du compas de tête, le galet est automatiquement écarté du sol dans la position surélevée, de sorte que les mouvements transversaux sont permis côté tête dans cette position, autorisant ainsi les grandes manoeuvres du lit, cependant que seuls les mouvements longitudinaux sont permis en position basse et en position élevée (et éventuellement proclive et déclive), au bénéfice de la sécurité du patient et de la préservation du mobilier jouxtant la tête de lit.Thus, thanks to the stop actuated by the leg of the head compass, the roller is automatically moved away from the ground in the raised position, so that the transverse movements are allowed side head in this position, thus allowing the large maneuvers of the bed, however only longitudinal movements are allowed in the low position and in the raised position (and possibly proclive and sloping), for the benefit of the safety of the patient and the preservation of furniture adjacent to the headboard.

Sur la figure 1 est représenté un lit 1 médicalisé, reposant sur un sol 2 et destiné à être utilisé de manière stationnaire, quoique temporairement mobile, en milieu hospitalier ou clinique, en maison médicalisée, ou encore au logement d'un patient recevant des soins à domicile.On the figure 1 there is shown a bed 1 medicalized, based on a floor 2 and intended to be used in a stationary manner, although temporarily mobile, in a hospital or clinic, in a nursing home, or home to a patient receiving home care.

Le lit 1 comprend un cadre 3 muni de longerons 4 et de traverses 5 reliant les longerons 4 à une extrémité avant (définissant un côté tête 6 du cadre 3 et plus généralement du lit 1) et à une extrémité arrière (définissant un côté pied 7 du cadre 3 et plus généralement du lit 1) de ceux-ci.The bed 1 comprises a frame 3 provided with longitudinal members 4 and cross members 5 connecting the longitudinal members 4 at a front end (defining a head 6 of the frame 3 and more generally of the bed 1 ) and at a rear end (defining a foot side 7 frame 3 and more generally bed 1 ) thereof.

Comme on le voit sur la figure 1, le lit 1 comprend en outre un sommier 8 monté sur le cadre 3. Dans l'exemple illustré, le sommier 8 comprend, pour le confort du patient, un relève-buste 9 qui s'étend côté tête 6 en étant articulé sur le cadre 3, ainsi qu'un relève-jambe 10 qui s'étend côté pied 7 en étant également articulé sur le cadre 3, formé d'une paire de panneaux mutuellement articulés. Le relève-buste 9 et le relève-jambe 10 sont couplés à des vérins de commande qui en déterminent les positions, via une télécommande à disposition du patient.As we see on the figure 1 , the bed 1 further comprises a bed base 8 mounted on the frame 3 . In the example shown, the bed base 8 comprises, for the comfort of the patient, a backrest 9 which extends head 6 being hinged to the frame 3 , and a leg rest 10 which extends side foot 7 being also articulated on the frame 3 , formed of a pair of mutually articulated panels. The backrest 9 and the legrest 10 are coupled to control cylinders which determine the positions, via a remote control available to the patient.

Le lit 1 comprend par ailleurs un dispositif 11 de réglage en hauteur du cadre 3 par rapport au sol 2.The bed 1 further comprises a device 11 for adjusting the height of the frame 3 relative to the ground 2 .

Le dispositif 11 de réglage comprend un compas 12 de tête monté sur le cadre 2 du côté tête 6, et un compas 13 de pied monté sur le cadre 3 du côté pied 7. En pratique, deux compas 12 de tête identiques sont prévus côté tête 6, de part et d'autre du cadre 3. De même, deux compas 13 de pied identiques sont prévus côté pied 7, de part et d'autre du cadre 3. Les deux compas 12 de tête, de même que les deux compas 13 de pied, sont solidarisés au moyen de barres 14 transversales les reliant.The adjusting device 11 comprises a head compass 12 mounted on the frame 2 of the head side 6 , and a foot compass 13 mounted on the frame 3 of the foot side 7 . In practice, two identical head compasses 12 are provided on the head side 6 , on either side of the frame 3 . Similarly, two identical foot compasses 13 are provided on the foot side 7 , on either side of the frame 3 . The two leading compasses 12 , as well as the two 13 foot compasses, are secured by means of transverse bars 14 connecting them.

Chaque compas 12, 13, en forme de Y, comprend une jambe 15 et une bielle 16 articulées mutuellement et par rapport au cadre 3.Each compass 12 , 13 , Y-shaped, comprises a leg 15 and a rod 16 articulated mutually and with respect to the frame 3 .

Plus précisément, dans l'exemple illustré, la jambe 15 présente une extrémité 17 supérieure par laquelle elle est articulée au cadre 3 par une liaison pivot glissant.More specifically, in the example shown, the leg 15 has an upper end 17 by which it is articulated to the frame 3 by a sliding pivot connection.

Cette liaison pivot glissant comprend par exemple un axe 18 roulant monté à l'extrémité 17 supérieure de la jambe 15, qui coopère avec une glissière 19 solidaire d'une une paroi latérale d'un longeron 4, cette glissière 19 ayant une extrémité 20 interne et une extrémité 21 externe opposées.This sliding pivot connection comprises for example a rolling pin 18 mounted at the upper end 17 of the leg 15 , which cooperates with with a slide 19 secured to a side wall of a spar 4 , this slide 19 having an inner end 20 and an opposite outer end 21 .

La bielle 16 présente une extrémité 22 supérieure par laquelle la bielle 16 est articulée au cadre 3 par une liaison 23 pivot, et une extrémité 24 inférieure par laquelle la bielle 16 est articulée à la jambe 15 par une autre liaison 25 pivot.The rod 16 has an upper end 22 through which the rod 16 is articulated to the frame 3 by a pivot connection 23 , and a lower end 24 by which the rod 16 is articulated to the leg 15 by another pivot connection 25 .

Chaque compas 12, 13 possède ainsi une position repliée dans laquelle, l'axe 18 roulant étant à proximité de l'extrémité 20 interne de la glissière 19, la jambe 15 jouxte le cadre 3, et une position déployée dans laquelle, l'axe 18 roulant étant situé du côté de l'extrémité 21 externe de la glissière 19, la jambe 15 est écartée (angulairement) du cadre 3.Each compass 12 , 13 thus has a folded position in which, the axis 18 rolling being close to the inner end 20 of the slideway 19 , the leg 15 adjoins the frame 3 , and an extended position in which, the axis 18 rolling being located on the side of the outer end 21 of the slide 19 , the leg 15 is spaced (angularly) from the frame 3 .

Chaque dispositif 11 de réglage comprend également un vérin 26 ayant un corps 27 monté articulé sur une traverse 5, et une tige 28 montée coulissante par rapport au corps 27 et montée articulée sur la barre 14 transversale. Les vérins 26 peuvent être commandés en synchronisme ou, le cas échéant, séparément, comme nous le verrons ci-après.Each adjusting device 11 also comprises a jack 26 having a body 27 mounted articulated on a crosspiece 5 , and a rod 28 slidably mounted relative to the body 27 and hingedly mounted on the crossbar 14 . The cylinders 26 can be controlled in synchronism or, if necessary, separately, as we will see below.

Le lit 1 comprend encore un train 29 arrière roulant. Ce train 29 arrière comprend un chariot 30 de pied articulé par rapport à la jambe 15 du compas 13 de pied, à une extrémité 31 inférieure de celle-ci, autour d'un pivot 32 transversal, et au moins une roue 33 arrière folle montée en libre rotation sur le chariot 30 de pied, de sorte à permettre, côté pied 7, les mouvements tant longitudinaux (matérialisés sur la figure 1 par la flèche L) que transversaux (matérialisés sur la figure 1 par la flèche T).The bed 1 further comprises a rear wheel 29 rolling. This rear train 29 comprises a foot carriage 30 articulated with respect to the leg 15 of the foot compass 13 , at a lower end 31 thereof, around a transverse pivot 32 , and at least one mounted rear wheel 33 mounted in free rotation on the trolley 30 foot, so as to allow, foot side 7 , the movements both longitudinal (materialized on the figure 1 by the arrow L) that transverse (materialized on the figure 1 by the arrow T).

Dans l'exemple illustré, le train 29 arrière comprend deux chariots 30 de pied articulés sur la jambe 15 de chaque compas 13 de pied ; on voit également que, dans cet exemple, chaque chariot 30 de pied comprend deux roues 33 arrière folles, qui sont avantageusement situées de part et d'autre du pivot 32. Selon un exemple de réalisation illustré sur les figures, le train 29 arrière comprend un essieu 34 avant qui relie les chariots 30 de pied, au bénéfice de la rigidité structurelle du train 29 arrière.In the illustrated example, the rear train 29 comprises two foot carriages 30 articulated on the leg 15 of each compass 13 foot; can also be seen that in this example, each carriage 30 comprises two wheels 33 foot crazy rear, which are advantageously located on either side of the pivot 32. According to an exemplary embodiment illustrated in the figures, the rear train 29 comprises a front axle 34 which connects the carriages 30 to the benefit of the structural rigidity of the rear train 29 .

Un frein 35 peut équiper le train 29 arrière, ce frein 35 ayant une position désengagée dans laquelle les roues 33 arrière sont libres en rotation pour permettre, côté pied 7, les mouvements tant longitudinaux que transversaux du lit 1, et une position engagée dans laquelle le frein 35 bloque au moins l'une des roues 33 arrière de sorte à interdire, côté pied 7, les mouvements tant longitudinaux que transversaux du lit 1.A brake 35 can equip the rear train 29 , this brake 35 having a disengaged position in which the rear wheels 33 are free in rotation to allow, on the foot side 7 , both longitudinal and transverse movements of the bed 1 , and an engaged position in which the brake 35 blocks at least one of the rear wheels 33 so as to prohibit, foot side 7 , the longitudinal movements only transverse of bed 1 .

Le lit 1 comprend, en outre, un train 36 avant roulant. Ce train 36 avant comprend un chariot 37 de tête articulé par rapport à la jambe 15 du compas 12 de tête, à l'extrémité 31 inférieure de celle-ci, autour d'un pivot 38 transversal, et au moins un galet 39 monté en rotation par rapport au chariot 37 de tête (et donc par rapport à la jambe 15) autour d'un axe 40 de roulage transversal. Tant que le galet 39 est en contact avec le sol 2 (nous verrons ci-après dans quelles conditions il peut en être écarté), il n'autorise, côté tête 6, que les mouvements longitudinaux du lit 1, qui sont nécessaires au réglage du lit 1 en hauteur (ainsi qu'à la mise en positions proclive et déclive) et s'oppose aux mouvements transversaux.The bed 1 further comprises a train 36 before rolling. This front gear 36 comprises a head carriage 37 articulated with respect to the leg 15 of the head compass 12 , at the lower end 31 thereof, around a transverse pivot 38 , and at least one roller 39 mounted on rotation relative to the carriage 37 of head (and therefore relative to the leg 15 ) about a transverse axis 40 of rolling. As long as the roller 39 is in contact with the ground 2 (we shall see below under which conditions it may be removed), it only allows, on the head side 6 , the longitudinal movements of the bed 1 , which are necessary for the adjustment of the bed 1 in height (as well as the setting in positions proclive and declivity) and opposes the transversal movements.

Outre le galet 39, le train 36 avant comprend au moins une roue 41 avant folle montée en rotation sur le chariot 37 de tête, autour d'un axe 42 de roulage (qui s'étend parallèlement au sol 2) et autour d'un axe 43 de lacet, qui dans certaines conditions (exposées ci-après) s'étend sensiblement perpendiculairement au sol 2.In addition to the roller 39 , the front gear 36 comprises at least one idler wheel 41 rotatably mounted on the carriage 37 of the head, about a driving axis 42 (which extends parallel to the ground 2 ) and around an yaw axis 43 , which under certain conditions (described below) extends substantially perpendicularly to the ground 2 .

Dans l'exemple illustré, le train 36 avant comprend deux chariots 37 de tête articulés sur la jambe 15 de chaque compas 12 de tête ; on voit également que, dans cet exemple, chaque chariot 37 de tête comprend une unique roue 41 avant folle et un unique galet 39, qui sont avantageusement situés de part et d'autre du pivot 38. Selon un exemple de réalisation illustré sur les figures, le train 36 avant comprend un essieu 44 avant qui relie les chariots 37 de tête, au bénéfice de la rigidité structurelle du train 36 avant.In the illustrated example, the front gear 36 comprises two head carriages 37 articulated on the leg 15 of each head compass 12 ; it is also seen that, in this example, each head carriage 37 comprises a single idler wheel 41 and a single roller 39 , which are advantageously located on either side of the pivot 38 . According to an exemplary embodiment illustrated in the figures, the front gear 36 comprises a front axle 44 which connects the carriages 37 at the head, to the advantage of the structural rigidity of the front gear 36 .

Selon un mode de réalisation illustré sur la figure 2, le chariot 37 de tête comprend une patte 45 qui s'étend transversalement et sur laquelle est montée la roue 41 avant. Le chariot 37 de tête comprend également une paroi 46 latérale, dans laquelle est ancré l'essieu 44 avant.According to an embodiment illustrated on the figure 2 , the head carriage 37 comprises a tab 45 which extends transversely and on which is mounted the wheel 41 before. The head carriage 37 also comprises a side wall 46 , in which is anchored the front axle 44 .

Ainsi qu'il est également représenté sur la figure 2, le galet 39 est monté en rotation dans une chape 47 ayant un flasque 48 externe (formé ici par la paroi 46 latérale du chariot 37 de tête), et un flasque 49 interne (solidaire ici de l'essieu 44 avant).As he is also represented on the figure 2 , the roller 39 is rotatably mounted in a yoke 47 having an outer flange 48 (here formed by the side wall 46 of the head carriage 37 ), and an inner flange 49 (integral here with the front axle 44 ).

Le chariot 37 de tête porte en outre une butée 50 agencée pour interagir, dans certaines conditions décrites ci-après, avec la jambe 15 du compas 12 de tête.The head carriage 37 further carries a stop 50 arranged to interact, under certain conditions described below, with the leg 15 of the compass 12 head.

Grâce à l'architecture qui vient d'être décrite, le lit 1 possède :

  • une position basse, illustrée sur la figure 3, dans laquelle les compas 12, 13 sont repliés et dans laquelle le cadre 3 est relativement proche du sol 2,
  • une position élevée (destinée aux soins prodigués au patient), illustrée sur la figure 4, dans laquelle les compas 12, 13 sont déployés (les axes 18 roulants des jambes étant situés du côté des extrémités 21 externes des glissières 19 sans toutefois être en fin de course) et dans laquelle le cadre 3 est relativement plus éloigné du sol 2 qu'en position basse.
With the architecture that has just been described, the bed 1 has:
  • a low position, illustrated on the figure 3 , in which the compasses 12 , 13 are folded and in which the frame 3 is relatively close to the ground 2 ,
  • a high position (for the care of the patient), illustrated on the figure 4 , in which the compasses 12 , 13 are deployed (the rolling axes 18 of the legs being situated on the side of the outer ends 21 of the slides 19 without however being at the end of the stroke) and in which the frame 3 is relatively further from the ground 2 qu 'in the low position.

Quelle que soit la position du lit 1, les roues 33 arrière sont toujours en contact avec le sol, grâce au montage articulé du chariot 30 de pied sur la jambe 15 du compas 13 de pied.Regardless of the position of the bed 1 , the rear wheels 33 are always in contact with the ground, thanks to the articulated mounting of the trolley 30 foot on the leg 15 of the compass 13 foot.

Dans la position basse du lit 1, les roues 41 avant sont en contact avec le sol ; il en va de même des galets 39 ; la butée 50 n'est pas en interaction avec la jambe 15 du compas 12 avant.In the low position of the bed 1 , the front wheels 41 are in contact with the ground; it is the same with pebbles 39 ; the stop 50 does not interact with the leg 15 of the compass 12 before.

Le diamètre des galets 39 et des roues 41 avant ainsi que le positionnement de leurs axes 40, 42 de roulage sont choisis de préférence pour qu'en position basse comme en position élevée, l'axe 43 de lacet soit incliné par rapport à la perpendiculaire au sol 2, de sorte que la roue 41 avant, dans l'impossibilité de pivoter autour de son axe 43 de lacet, soit astreinte comme le galet 39 à un mouvement de roulement dans la direction longitudinale. De la sorte, le train 36 avant est contraint à se déplacer selon la direction longitudinale.The diameter of the rollers 39 and the front wheels 41 as well as the positioning of their rolling axes 40 , 42 are preferably chosen so that in the low position as in the raised position, the yaw axis 43 is inclined with respect to the perpendicular on the ground 2 , so that the wheel 41 before, in the impossibility of pivoting about its yaw axis 43 , is constrained as the roller 39 to a rolling movement in the longitudinal direction. In this way, the front gear 36 is forced to move in the longitudinal direction.

Ces positions sont adoptées par le lit 1 sous la commande synchronisée des deux vérins 26, dont les tiges 28 coulissent de concert dans les corps 27 de sorte à maintenir constante (et horizontale) l'assiette du cadre 3.These positions are adopted by the bed 1 under the synchronized control of the two cylinders 26 , whose rods 28 slide together in the bodies 27 so as to maintain constant (and horizontal) the plate of the frame 3 .

Il est envisageable de commander séparément ou en opposition les vérins 36, de sorte à permettre au lit 1 d'adopter une position proclive (figure 5) dans laquelle le côté tête 6 est plus haut que le côté pied 7, ou inversement une position déclive (figure 6) dans laquelle le côté tête 6 est, au contraire, plus bas que le côté pied 7. Tant dans la position proclive que dans la position déclive, les roues 33 arrière, les roues 41 avant et les galets 39 sont tous en contact avec le sol 2 ; la butée 50 n'interagit pas avec la jambe 15 du compas 12 avant.It is conceivable to order separately or in opposition the jacks 36 , so as to allow the bed 1 to adopt a proclive position ( figure 5 ) in which the head side 6 is higher than the foot side 7 , or conversely a sloping position ( figure 6 ) in which the head side 6 is, on the contrary, lower than the foot side 7 . Both in the proclive position and in the sloping position, the wheels 33 back, the wheels 41 before and the rollers 39 are all in contact with the ground 2 ; the stop 50 does not interact with the leg 15 of the compass 12 before.

Le lit 1 possède en outre une position surélevée (figure 7) dans laquelle les compas 12, 13 sont déployés jusqu'en fin de course (les axes 18 roulants des jambes 15 étant au plus proche des extrémités 21 externes des glissières 19), et dans laquelle la jambe 15 du compas 12 de tête place, par interaction avec la butée 50, le chariot 37 de tête dans une position basculée (autour de l'axe 42 de roulage de la roue 41 avant) dans laquelle :

  • le galet 39 est écarté du sol 2, et
  • l'axe 43 de lacet de la roue 41 avant est sensiblement perpendiculaire au sol 2.
The bed 1 also has an elevated position ( figure 7 ) in which the compasses 12 , 13 are deployed to the end of travel (the rolling axes 18 of the legs 15 being as close as possible to the outer ends 21 of the slides 19 ), and in which the leg 15 of the head compass 12 places, by interaction with the abutment 50 , the head carriage 37 in a tilted position (around the axis 42 of rolling of the front wheel 41 ) in which:
  • the roller 39 is spaced from the ground 2 , and
  • the yaw axis 43 of the front wheel 41 is substantially perpendicular to the ground 2 .

Il en résulte que la roue 41 avant peut librement pivoter autour de son axe 43 de lacet. Le galet 39 étant par ailleurs surélevé par rapport au sol 2, le train 36 avant autorise ainsi les mouvements tant longitudinaux que transversaux du lit 1 côté tête 6, au bénéfice de la mobilité de celui-ci lors des grandes manoeuvres.As a result, the front wheel 41 can freely rotate about its yaw axis 43 . The roller 39 is also raised above the ground 2 , the front train 36 thus authorizes the longitudinal and transverse movements of the bed 1 head side 6 , to the benefit of mobility thereof during major maneuvers.

La butée 50 peut être agencée pour interagir directement avec la jambe 15 du compas 12 de tête. A cet effet, la butée 50 s'étend par exemple en regard d'une face 51 arrière de la jambe 15 et, en position surélevée du lit 1, la butée 50 est appliquée contre cette face 51 arrière.The stop 50 can be arranged to interact directly with the leg 15 of the compass 12 head. For this purpose, the abutment 50 extends for example opposite a rear face 51 of the leg 15 and, in the raised position of the bed 1 , the stop 50 is applied against this rear face 51 .

Selon un mode préféré de réalisation illustré sur les figures, et plus particulièrement visible sur la figure 2 , la butée 50 est formée par une languette en saillie, par exemple à partir d'un bord 52 transversal avant de la patte 45. Cette configuration permet une réalisation simple et monobloc du chariot 37 de tête, notamment par découpe et pliage d'une tôle métallique (typiquement une tôle d'acier).According to a preferred embodiment illustrated in the figures, and more particularly visible on the figure 2 the abutment 50 is formed by a projecting tab, for example from a transverse edge 52 before the tab 45 . This configuration allows a simple and monobloc embodiment of the carriage 37 of the head, in particular by cutting and folding a metal sheet (typically a steel sheet).

Afin de répartir la charge, la languette 50 présente par exemple une section 53 distale recourbée, qui vient s'appliquer contre la face 51 arrière de la jambe 15 en position surélevée du lit 1. L'appui de la jambe 15 contre la butée 50 génère ainsi, autour du point (ou de la ligne) de contact de la roue 41 avant avec le sol, un couple qui fait basculer le chariot 37 de tête, comme indiqué par la flèche courbe dans le médaillon de détail de la figure 7.In order to distribute the load, the tongue 50 has for example a curved distal section 53 , which is applied against the rear face 51 of the leg 15 in the raised position of the bed 1 . The support of the leg 15 against the stop 50 thus generates, around the point (or the line) of contact of the wheel 41 before with the ground, a torque that tilts the carriage 37 head, as indicated by the arrow curve in the detail medallion of the figure 7 .
