Description

La présente invention concerne le domaine des chariots de transport pour patient que l'on trouve habituellement dans les hôpitaux, notamment dans les services des urgences. Ce type de chariot porte également le nom de chariot-brancard.The present invention relates to the field of patient transport trolleys that are usually found in hospitals, especially in emergency departments. This type of trolley is also called a stretcher trolley.

La présente invention porte plus précisément sur un chariot de transport pour patient comportant :

  • châssis inférieur muni de roues ;
  • un châssis supérieur comportant un couchage présentant une direction longitudinale, ledit châssis supérieur présentant un côté tête et un côté pieds, le châssis supérieur étant relié au châssis inférieur par l'intermédiaire d'un premier bras de levage et d'un second bras de levage permettant le déplacement du châssis supérieur par rapport au châssis inférieur.
The present invention relates more specifically to a patient transport trolley comprising:
  • lower frame with wheels;
  • an upper frame having a coating having a longitudinal direction, said upper frame having a head and a foot side, the upper frame being connected to the lower frame via a first lift arm and a second lift arm allowing movement of the upper frame relative to the lower frame.

Dans ce type de chariot, les extrémités supérieures des bras sont généralement montées pivotantes par rapport au châssis supérieur. Les bras de levage sont parfois articulés en plusieurs points, ce qui rend leur réalisation assez complexe.In this type of trolley, the upper ends of the arms are generally pivotally mounted relative to the upper frame. The lifting arms are sometimes articulated in several points, which makes their realization quite complex.

Objet et résumé de l'inventionObject and summary of the invention

Un but de l'invention est de proposer un chariot de transport pour un patient présentant une alternative aux chariots-brancards à hauteur variable connus.An object of the invention is to provide a transport trolley for a patient having an alternative to known height-adjustable trolleys.

L'invention atteint son but par le fait que les premier et second bras de levage sont montés pivotants au châssis inférieur autour d'axes de rotation distincts perpendiculaires à la direction longitudinale du couchage, et sont actionnés indépendamment l'un de l'autre grâce à des premier et second actionneurs fixés au châssis inférieur, le premier bras de levage présentant :

  • une extrémité supérieure montée pivotante au côté pieds du châssis supérieur du côté pieds, et
  • une extrémité inférieure reliée au premier actionneur, tandis que le second bras de levage présente :
  • une extrémité supérieure montée coulissante et pivotante par rapport au côté tête du châssis supérieur, et
  • une extrémité inférieure reliée au second actionneur.
The invention achieves its object by the fact that the first and second lifting arms are pivotally mounted to the lower frame around distinct axes of rotation perpendicular to the longitudinal direction of the coating, and are actuated independently of one another by first and second actuators attached to the lower frame, the first lift arm having:
  • an upper end pivotally mounted to the foot side of the upper frame of the feet side, and
  • a lower end connected to the first actuator, while the second lifting arm has:
  • an upper end slidably and pivotally mounted relative to the head side of the upper frame, and
  • a lower end connected to the second actuator.

Ainsi, les premier et deuxième bras de levage sont uniquement articulés par rapport au châssis inférieur et supérieur, et non pas en davantage de points à l'instar de certaines solutions existantes par ailleurs. Cela permet de faciliter la fabrication des bras de levage, mais aussi de les renforcer, ce qui améliore la robustesse du chariot.Thus, the first and second lift arms are articulated only with respect to the lower and upper frame, and not in more ways like some existing solutions elsewhere. This facilitates the manufacture of the lift arms, but also to strengthen them, which improves the robustness of the truck.

Les deux actionneurs permettent de faire pivoter les premier et second bras de levage de manière indépendante l'un par rapport à l'autre, ce qui permet de régler facilement l'angle d'inclinaison du couchage.Both actuators allow the first and second lift arms to be pivoted independently of each other, which makes it easy to adjust the angle of inclination of the coating.

De préférence, les actionneurs sont des vérins, de type pneumatique.Preferably, the actuators are cylinders, pneumatic type.

Avantageusement, le châssis supérieur comporte deux éléments de support longitudinaux s'étendant de part et d'autre du couchage, et l'extrémité supérieure du premier bras est montée pivotante à chacun des éléments de support.Advantageously, the upper frame comprises two longitudinal support members extending on either side of the coating, and the upper end of the first arm is pivotally mounted to each of the support elements.

On comprend donc que la liaison entre l'extrémité supérieure du premier bras de levage et le châssis supérieur se fait en deux points.It is therefore understood that the connection between the upper end of the first lifting arm and the upper frame is at two points.

De préférence, l'extrémité supérieure comprend une traverse qui s'étend perpendiculairement au premier bras de levage et dont les deux extrémités sont montées en liaison pivot par rapport au châssis supérieur.Preferably, the upper end comprises a cross member extending perpendicularly to the first lifting arm and whose two ends are mounted in pivot connection relative to the upper frame.

Selon un premier mode de réalisation, l'extrémité supérieure du second bras coopère uniquement avec l'un des deux éléments de support longitudinaux.According to a first embodiment, the upper end of the second arm cooperates only with one of the two longitudinal support members.

On comprend donc que la liaison entre l'extrémité supérieure du second bras de levage et le châssis supérieur se fait en un seul point. Autrement dit, le second bras est monté en porte-à-faux et reprend en un seul point le poids du châssis supérieur côté tête.It is therefore understood that the connection between the upper end of the second lifting arm and the upper frame is at a single point. In other words, the second arm is mounted cantilever and takes back in one point the weight of the upper frame head.

Un intérêt de ce premier mode de réalisation est que, en l'absence d'un second point de liaison entre le second bras de levage et le côté tête du châssis supérieur, la zone située sous le côté tête du châssis supérieur est largement dégagée, ce qui permet de placer facilement un appareil médical sous le châssis supérieur, ou bien encore permet au médecin de pouvoir s'installer facilement et confortablement à proximité de la partie supérieure du corps du patient.An advantage of this first embodiment is that, in the absence of a second connection point between the second lifting arm and the head side of the upper frame, the area below the head side of the upper frame is largely free, which makes it easy to place a medical device under the upper frame, or even allows the doctor to be easily and comfortably installed near the upper part of the patient's body.

Pour permettre le déplacement du second bras de levage par rapport au châssis supérieur lors de la montée ou de la descente de ce dernier, l'extrémité supérieure du second bras est munie d'un sabot articulé qui est engagé dans un rail de guidage fixé sous le côté tête du châssis supérieur. De préférence, on utilise un rail technique.In order to allow the second lifting arm to move with respect to the upper chassis when the latter is raised or lowered, the upper end of the second arm is provided with an articulated shoe which is engaged in a guide rail fixed under the head side of the upper frame. Preferably, a technical rail is used.

On comprend que le rail de guidage est fixé sous l'un des éléments de support longitudinaux précités.It is understood that the guide rail is fixed under one of the aforementioned longitudinal support elements.

Selon un second mode de réalisation de l'invention, l'extrémité supérieure du second bras est munie d'une barre transversale qui comporte un galet à chacune de ses deux extrémités, chacun des éléments de support longitudinaux comporte une glissière disposée du côté tête du châssis supérieur, et les galets coopèrent avec les glissières afin de permettre le coulissement de l'extrémité supérieure du second bras par rapport au côté tête du châssis supérieur.According to a second embodiment of the invention, the upper end of the second arm is provided with a transverse bar which comprises a roller at each of its two ends, each of the longitudinal support elements comprises a slide disposed on the head side of the upper frame, and the rollers cooperate with the slideways to allow the sliding of the upper end of the second arm relative to the head side of the upper frame.

On comprend donc que la liaison entre l'extrémité supérieure du second bras de levage et le châssis supérieur se fait en deux points. Un avantage du second mode de réalisation du chariot par rapport au premier est qu'il est moins onéreux dans la mesure où il ne nécessite pas un rail capable de supporter un montage en porte-à-faux.It is therefore understood that the connection between the upper end of the second lifting arm and the upper frame is at two points. An advantage of the second embodiment of the carriage with respect to the first is that it is less expensive in that it does not require a rail capable of supporting cantilever mounting.

Selon un autre aspect avantageux de la présente invention considérée dans un plan horizontal, le châssis inférieur présente la forme d'un « U » constitué de deux portions transversales reliées par une portion longitudinale, les liaisons pivots des premier et second bras de levage étant situées dans la portion longitudinale, tandis que les extrémités des portions transversales portent les roues du chariot.According to another advantageous aspect of the present invention considered in a horizontal plane, the lower frame has the shape of a "U" consisting of two transverse portions connected by a longitudinal portion, the pivot links of the first and second lifting arms being located in the longitudinal portion, while the ends of the transverse portions carry the wheels of the carriage.

On comprend donc que les bras de levage sont déportés sur un bord latéral du chariot afin de dégager un espace sous le châssis supérieur, grâce à quoi le chariot-brancard selon l'invention peut être amené sous un équipement de radiologie, tel un amplificateur de brillance, ou tout autre appareil médical nécessitant un accès à une zone située sous le patient en position couchée. Ces appareils présentent le plus souvent une portion en arc dont les extrémités sont placées au-dessus et en-dessous du couchage. Un tel appareil est notamment illustré en figure 1 de US 6 574 493 .It is therefore understood that the lifting arms are offset on a lateral edge of the carriage to clear a space under the upper frame, whereby the stretcher trolley according to the invention can be brought under a radiology equipment, such as an amplifier. shine, or any other medical device requiring access to an area under the patient lying down. These devices most often have an arc portion whose ends are placed above and below the coating. Such an apparatus is particularly illustrated in figure 1 of US 6,574,493 .

La forme en « U » du châssis inférieur facilite également le positionnement du chariot sous un tel appareil, dans la mesure où la partie inférieure de la portion en arc de l'amplificateur de brillance peut se loger entre les deux portions transversales du châssis inférieur. On comprend en particulier que les bras de levage, déportés sur un côté du chariot, ne gênent pas le positionnement du chariot sous l'appareil de radiologie.The "U" shape of the lower frame also facilitates the positioning of the carriage under such an apparatus, insofar as the lower portion of the arc portion of the image intensifier can be housed between the two transverse portions of the lower frame. It is understood in particular that the lift arms, offset on one side of the carriage, do not interfere with the positioning of the carriage under the radiology apparatus.

Dans le cas du premier mode de réalisation décrit ci-dessus, l'extrémité supérieure du second bras coopère uniquement avec l'élément de support longitudinal qui est disposé du côté de la portion longitudinale, ce qui permet de dégager encore davantage d'espace sous le châssis supérieur.In the case of the first embodiment described above, the upper end of the second arm cooperates only with the longitudinal support member which is arranged on the side of the longitudinal portion, which allows to release even more space under the upper frame.

Selon un autre aspect de l'invention, les corps des actionneurs sont fixés en partie centrale de la portion longitudinale, tandis que leurs tiges s'étendent vers les portions transversales. Les actionneurs, en l'espèce les deux vérins, sont donc montés dos à dos. Ce montage présente l'intérêt d'être compact, les actionneurs étant également déportés sur un bord latéral du chariot. De préférence, les actionneurs sont fixés en dessous de la portion longitudinale.According to another aspect of the invention, the bodies of the actuators are fixed in the central part of the longitudinal portion, while their rods extend towards the transverse portions. The actuators, in this case the two cylinders, so are mounted back to back. This arrangement has the advantage of being compact, the actuators also being offset on a side edge of the carriage. Preferably, the actuators are fixed below the longitudinal portion.

Encore de préférence, les premier et second bras de levage présentent des portions arquées ayant la forme d'un « C » tournées vers les extrémités longitudinales du chariot.Still preferably, the first and second lift arms have curved portions in the form of a "C" facing the longitudinal ends of the carriage.

Description détailléedetailed description

Sur la figure 1 , on a représenté en perspective un premier mode de réalisation d'un chariot de transport 10 pour un patient. Ce type de chariot, également appelé chariot-brancard, est principalement destiné à être utilisé en milieu hospitalier, notamment dans les services des urgences.On the figure 1 , there is shown in perspective a first embodiment of a transport carriage 10 for a patient. This type of trolley, also called stretcher trolley, is mainly intended for use in hospitals, especially in emergency departments.

Le chariot de transport 10 comprend un châssis inférieur 12 muni de quatre roues 14 permettant le déplacement du chariot.The transport carriage 10 comprises a lower frame 12 provided with four wheels 14 for moving the carriage.

Comme on le constate sur cette figure, le châssis inférieur 12, considéré dans un plan horizontal, présente la forme d'un « U » constitué de deux portions transversales 16 reliées entre elles par une portion longitudinale 18. As can be seen in this figure, the lower frame 12, considered in a horizontal plane, has the shape of a "U" consisting of two transverse portions 16 interconnected by a longitudinal portion 18.

On précise que les expressions « longitudinale » et « transversale » sont considérées par rapport à la direction longitudinale L dans laquelle s'étend le couchage du chariot de transport 10. It is specified that the expressions "longitudinal" and "transverse" are considered with respect to the longitudinal direction L in which the coating of the transport carriage 10 extends .

En se référant à la figure 3 , on constate que l'ossature du châssis inférieur 12 peut être recouverte d'un carter de protection 20 qui présente lui aussi la forme d'un « U ».Referring to the figure 3 it is found that the frame of the lower frame 12 may be covered with a protective housing 20 which also has the shape of a "U".

En se référant à nouveau à la figure 1 , on constate que les quatre roues 14 du chariot 10 sont fixées aux extrémités des portions transversales 16 et de la portion transversale 18 de manière que les points d'attache des roues 14 se situent sur les sommets d'un rectangle. On précise également que, dans cet exemple, les portions transversales 16 sont perpendiculaires à la portion longitudinale 18. Referring again to the figure 1 it is found that the four wheels 14 of the carriage 10 are fixed at the ends of the transverse portions 16 and the transverse portion 18 so that the attachment points of the wheels 14 are located on the vertices of a rectangle. It is also specified that, in this example, the transverse portions 16 are perpendicular to the longitudinal portion 18.

Le chariot de transport 10 comporte en outre un châssis supérieur 22 comportant un couchage 24 qui est constitué ici d'un matelas 26. Le châssis supérieur 22 est constitué d'un cadre rectangulaire 28 qui est muni de deux éléments longitudinaux 29, 31, les premier et second éléments longitudinaux 30, 32 étant parallèles et distants.The transport carriage 10 further comprises an upper frame 22 comprising a coating 24 which is constituted here of a mattress 26. The upper frame 22 consists of a rectangular frame 28 which is provided with two longitudinal elements 29, 31, the first and second longitudinal members 30, 32 being parallel and remote.

Sur la figure 1 , on comprend que les éléments longitudinaux 30, 32 s'étendent de part et d'autre du matelas 26. On the figure 1 it is understood that the longitudinal elements 30, 32 extend on either side of the mattress 26.

Le châssis supérieur 22 présente un côté tête 22a et un côté pied 22b. La partie du couchage qui est située du côté tête 22a peut pivoter par rapport au reste du couchage comme on peut le comprendre en se référant à la figure 4 . The upper frame 22 has a head 22a and a foot 22b side . The part of the coating which is located on the head side 22a can pivot relative to the rest of the coating as can be understood by referring to the figure 4 .

En se référant à nouveau à la figure 1 , on constate que le châssis supérieur 22, et plus précisément le cadre 28, est relié au châssis inférieur 12 par l'intermédiaire d'un premier bras de levage 30 et d'un second bras de levage 32 qui permettent le déplacement du châssis supérieur 22 par rapport au châssis inférieur 12. Referring again to the figure 1 , it is found that the upper frame 22, and more precisely the frame 28, is connected to the lower frame 12 via a first lifting arm 30 and a second lifting arm 32 which allow the displacement of the upper frame 22 relative to the lower frame 12.

Ces deux bras de levage 30, 32 permettent de régler la hauteur du châssis supérieur 22 mais aussi son inclinaison par rapport à un plan horizontal.These two lifting arms 30, 32 make it possible to adjust the height of the upper frame 22 but also its inclination with respect to a horizontal plane.

En se référant maintenant à la figure 2 , on constate que le premier bras de levage 30 est monté pivotant à la portion longitudinale 18 autour d'un axe de pivotement A qui est perpendiculaire à la direction longitudinale L du couchage.Referring now to the figure 2 , it is found that the first lifting arm 30 is pivotally mounted to the longitudinal portion 18 about a pivot axis A which is perpendicular to the longitudinal direction L of the coating.

Le second bras de levage 32 est quant à lui monté pivotant à la portion longitudinale 18 autour d'un axe de pivotement B, ce dernier étant également perpendiculaire à la direction longitudinale L du couchage. Les axes de rotation A et B sont distincts.The second lifting arm 32 is pivotally mounted to the longitudinal portion 18 about a pivot axis B, the latter also being perpendicular to the longitudinal direction L of the coating. The axes of rotation A and B are distinct.

Les premier et second bras de levage 30, 32 sont symétriques l'un par rapport à l'autre par rapport à un plan vertical perpendiculaire à la direction longitudinale L du couchage.The first and second lifting arms 30, 32 are symmetrical with respect to each other with respect to a vertical plane perpendicular to the longitudinal direction L of the coating.

Le premier bras de levage 30 comporte une première poutre 34 fixée à une première portion arquée 36, tandis que le second bras de levage 32 comporte une seconde poutre 38 fixée solidairement à une seconde portion arquée 40. Les première et seconde portions arquées 36, 40 présentent la forme d'un « C » tourné vers l'extérieur du chariot.The first lift arm 30 has a first beam 34 attached to a first arcuate portion 36, while the second lift arm 32 includes a second beam 38 integrally attached to a second arcuate portion 40. The first and second arcuate portions 36, 40 have the shape of a "C" facing the outside of the carriage.

Comme on le voit sur la figure 2 , ce sont plus précisément les première et seconde portions arquées 36, 40 qui sont fixées de manière pivotante à la portion longitudinale 18. As we see on the figure 2 , More precisely the first and second arcuate portions 36, 40 which are pivotally attached to the longitudinal portion 18.

Comme on le constate sur la figure 2 , l'extrémité supérieure 30a du premier bras de levage 30 constituée par l'extrémité supérieure 34a de la première poutre est montée pivotante au côté pied 22b du châssis supérieur 22. As we see on the figure 2 , the upper end 30a of the first lifting arm 30 constituted by the upper end 34a of the first beam is pivotally mounted to the foot side 22b of the upper frame 22.

L'extrémité inférieure 30b du premier bras de levage 30, en l'espèce constitué par l'extrémité inférieure 34b de la première portion arquée 34, est reliée de manière pivotante à l'extrémité d'une tige 50 d'un premier actionneur 52. Ce premier actionneur 52 est un vérin pneumatique qui comporte un corps 54 fixé de manière pivotante à une plaque 56 qui est elle-même fixée à la portion longitudinale 18. The lower end 30b of the first lifting arm 30, in this case consisting of the lower end 34b of the first arcuate portion 34, is pivotally connected to the end of a rod 50 of a first actuator 52. . This first actuator 52 is a pneumatic cylinder having a body 54 pivotally attached to a plate 56 which is itself secured to the longitudinal portion 18.

Comme on le voit à la figure 2 , cette plaque 56 est fixée en dessous de la portion longitudinale 18. As we see in figure 2 This plate 56 is attached below the longitudinal portion 18.

On précise que l'axe de pivotement entre le premier bras de levage 30 et le premier actionneur 52, ainsi que l'axe de pivotement D du corps 54 du premier actionneur 52 par rapport au châssis inférieur 12 sont parallèles entre eux et perpendiculaires à la direction longitudinale L du couchage.It is specified that the axis of pivoting between the first lifting arm 30 and the first actuator 52, as well as the pivot axis D of the body 54 of the first actuator 52 relative to the lower frame 12 are parallel to each other and perpendicular to the longitudinal direction L of the bedding.

On ajoute que l'axe de rotation E du premier bras de levage 30 par rapport au châssis supérieur 22 est également perpendiculaire à la direction longitudinale L du plan de couchage.It is added that the axis of rotation E of the first lifting arm 30 relative to the upper frame 22 is also perpendicular to the longitudinal direction L of the coating plane.

A l'aide de cette figure 2 , on comprend donc que le premier bras de levage 30 est actionné grâce au premier actionneur 52. Plus précisément, l'actionnement du premier actionneur 52 dans un sens où la tige 50 est rétractée dans le corps 54, provoque la descente du côté pied 22b du châssis supérieur 22 tandis que le déploiement de la tige 50 hors du corps 54 entraîne la levée du côté pied 22b du châssis supérieur 22. With the help of this figure 2 , It is therefore understood that the first lifting arm 30 is actuated by the first actuator 52. More specifically, actuation of the first actuator 52 in a direction where the rod 50 is retracted into the body 54 causes the descent of the foot side 22b of the upper frame 22 while the deployment of the rod 50 out of the body 54 causes the lifting of the foot side 22b of the upper frame 22.

On précise encore que l'axe de rotation E du premier bras de levage par rapport au châssis supérieur 22 et l'axe de pivotement D du premier actionneur 52 par rapport au châssis inférieur sont disposés de part et d'autre d'un plan vertical passant par l'axe de pivotement du premier bras de levage 30 par rapport au châssis inférieur.It is further specified that the axis of rotation E of the first lifting arm relative to the upper frame 22 and the pivot axis D of the first actuator 52 relative to the lower frame are arranged on either side of a vertical plane. passing through the pivot axis of the first lifting arm 30 relative to the lower frame.

En se référant aux figures 1 et 3 , on constate que l'extrémité supérieure du premier bras 30a est montée pivotante à chacun des éléments de support 29, 31 du châssis supérieur. En l'espèce, l'extrémité supérieure 30a du premier bras de levage 30 comporte une première traverse 60 fixée solidairement à l'extrémité supérieure de la première poutre 34, les extrémités 60a et 60b de cette première traverse étant montées pivotantes aux deux éléments de support longitudinaux 29, 31. Referring to figures 1 and 3 it is found that the upper end of the first arm 30a is pivotally mounted to each of the support members 29, 31 of the upper frame. In this case, the upper end 30a of the first lifting arm 30 comprises a first cross member 60 secured integrally to the upper end of the first beam 34, the ends 60a and 60b of this first cross member being pivotally mounted to the two elements of longitudinal support 29, 31.

L'extrémité supérieure 30a du premier bras de levage 30 est fixée à proximité de l'extrémité 60a de la première traverse 60 de sorte que le premier bras de levage 30 est déporté par rapport au châssis supérieur 22 du côté de la portion longitudinale 18. The upper end 30a of the first lifting arm 30 is fixed near the end 60a of the first cross member 60 so that the first lifting arm 30 is offset relative to the upper frame 22 on the side of the longitudinal portion 18.

En se référant à nouveau à la figure 2 , on constate que l'extrémité inférieure 32b du second bras de levage 32, constitué par l'extrémité inférieure 40a de la seconde portion arquée 40, est fixée de manière pivotante autour d'un axe F à l'extrémité d'une tige 70 d'un second actionneur 72. Ce second actionneur 72 comporte un corps 74 qui est monté pivotant autour d'un axe de pivotement G par rapport à la plaque 56 précitée.Referring again to the figure 2 It is found that the lower end 32b of the second lifting arm 32, consisting of the lower end 40a of the second arcuate portion 40 is pivotally attached about an axis F at the end of a rod 70 a second actuator 72. This second actuator 72 comprises a body 74 which is pivotally mounted about a pivot axis G with respect to the aforementioned plate 56 .

On constate donc que les premier et second vérins pneumatiques sont positionnés de manière symétrique par rapport à un plan vertical perpendiculaire à la direction longitudinale L du couchage.It is therefore found that the first and second pneumatic cylinders are positioned symmetrically with respect to a vertical plane perpendicular to the longitudinal direction L of the coating.

Dans ce premier mode de réalisation, le second bras de levage 32 présente une extrémité supérieure 32a qui est montée coulissante et pivotante par rapport au côté tête 22a du châssis supérieur 22. In this first embodiment, the second lift arm 32 has an upper end 32a which is slidably and pivotally mounted relative to the head side 22a of the upper frame 22.

On comprend que le coulissement de l'extrémité supérieure 32a du second bras de levage 32 par rapport au châssis supérieur permet de lever ou de baisser le couchage tout en le maintenant dans un plan horizontal.It is understood that the sliding of the upper end 32a of the second lifting arm 32 relative to the upper frame makes it possible to raise or lower the coating while maintaining it in a horizontal plane.

Dans ce premier mode de réalisation, l'extrémité supérieure 32a du second bras 32 coopère uniquement avec l'un des deux éléments de support longitudinaux. Cela est bien visible sur la figure 1 . Pour ce faire, dans cet exemple, l'extrémité supérieure 32a du second bras 32 est munie d'un sabot 80 qui est monté pivotant par rapport à l'extrémité supérieure 32a du second bras de levage autour d'un axe de pivotement H, ce sabot 80 étant engagé avec un rail de guidage 82 qui est fixé sous le côté tête 22a du châssis supérieur 22. In this first embodiment, the upper end 32a of the second arm 32 cooperates only with one of the two elements of longitudinal support. This is clearly visible on the figure 1 . To do this, in this example, the upper end 32a of the second arm 32 is provided with a shoe 80 which is pivotally mounted relative to the upper end 32a of the second lifting arm about a pivot axis H, this shoe 80 being engaged with a guide rail 82 which is fixed under the head side 22a of the upper frame 22.

On comprend que, lorsqu'on souhaite abaisser le châssis supérieur 22, on actionne les premier et second actionneurs 52, 72 de manière à faire pivoter les premier et second bras de levage dans un sens dans lequel on abaisse les extrémités supérieures des premier et second bras de levage. Dans cet exemple, ce mouvement est réalisé en rétractant les tiges 50, 70. Cela provoque l'éloignement relatif des extrémités supérieures 30a et 32a des premier et second bras de levage. Comme l'extrémité supérieure 30a du premier bras de levage est fixe par rapport au châssis supérieur, on comprend que, dans le mouvement de descente, le sabot 80 coulisse le long du rail de guidage 82 de manière à s'éloigner de l'extrémité supérieure 30a du premier bras de levage 30 ; en d'autres termes, le sabot 80 se rapproche de l'extrémité longitudinale du châssis supérieur 22 disposé du côté tête 22a. It is understood that, when it is desired to lower the upper frame 22, the first and second actuators 52, 72 are actuated so as to pivot the first and second lifting arms in a direction in which the upper ends of the first and second are lowered. lifting arm. In this example, this movement is achieved by retracting the rods 50, 70. This causes the relative distance of the upper ends 30a and 32a of the first and second lifting arms. Since the upper end 30a of the first lifting arm is fixed relative to the upper frame, it is understood that, in the downward movement, the shoe 80 slides along the guide rail 82 so as to move away from the end upper 30a of the first lifting arm 30; in other words, the shoe 80 is close to the longitudinal end of the upper frame 22 disposed on the head side 22a.

Bien évidemment, sans sortir du cadre de la présente invention, le bras monté coulissant et pivotant par rapport au châssis supérieur pourrait être disposé du côté pied 22b. Cela revient à intervertir les premier et second bras de levage de la figure 2 . Of course, without departing from the scope of the present invention, the arm mounted to slide and pivot relative to the upper frame could be arranged on the foot side 22b. This amounts to reversing the first and second lift arms of the figure 2 .

Sur la figure 4 , on a représenté un second mode de réalisation du chariot selon la présente invention.On the figure 4 , there is shown a second embodiment of the carriage according to the present invention.

Le chariot selon le second mode de réalisation est similaire au premier mode de réalisation. Il s'en distingue cependant par la structure du second bras de levage 320. Comme on le distingue sur cette figure, l'extrémité supérieure 320a du second bras de levage 320 est fixée solidairement à une seconde traverse 322 qui s'étend perpendiculairement par rapport au second bras de levage 320. Les extrémités longitudinales de cette seconde traverse 322 sont pourvues de galets 324 qui coopèrent avec des glissières 326 et 328 qui sont montées en dessous des éléments de support 29, 31 du côté tête du châssis supérieur 22. Dans ce second mode de réalisation, l'extrémité supérieure 320a du second bras de levage 320 est là encore montée coulissante et pivotante par rapport au côté tête du châssis supérieur. On comprend que les galets 324, qui coopèrent avec les glissières 326, 328 permettent le coulissement de l'extrémité supérieure 320a du second bras 320 par rapport au côté tête du châssis supérieur.The carriage according to the second embodiment is similar to the first embodiment. However, it is distinguished by the structure of the second lifting arm 320. As can be seen in this figure, the upper end 320a of the second lifting arm 320 is integrally fixed to a second cross member 322 which extends perpendicular to the second lifting arm 320. The longitudinal ends of this second cross member 322 are provided with rollers 324 which cooperate with slides 326 and 328 which are mounted below the support members 29, 31 of the head side of the upper frame 22. . in this second embodiment, the upper end 320a of the second lift arm 320 is again slidably and pivotally mounted relative to the head side of the upper frame. It is understood that the rollers 324, which cooperate with the slides 326, 328 allow the sliding of the upper end 320a of the second arm 320 relative to the head side of the upper frame.

Dans ce second mode de réalisation, les premier et second bras de levage sont reliés en quatre points au châssis supérieur.In this second embodiment, the first and second lift arms are connected at four points to the upper frame.

L'ensemble de la description ci-dessus est donné à titre d'exemple, et n'est donc pas limitatif de l'invention.The whole of the description above is given by way of example, and is therefore not limitative of the invention.
