Description

La présente invention concerne une plateforme de nacelle élévatrice, ainsi qu'une nacelle élévatrice équipée d'une telle plateforme.The present invention relates to a platform of aerial platform, as well as an aerial platform equipped with such a platform.

De manière classique, une nacelle élévatrice comprend un châssis motorisé, des roues, un mât télescopique articulé sur le châssis et une plateforme mobile où peut se tenir un opérateur, agencée à l'extrémité du mât télescopique. La plateforme dispose d'un poste de commande permettant à l'opérateur de piloter le mouvement de la plateforme. Lorsque l'opérateur est installé au poste de commande, il est généralement tourné vers le mât télescopique, ce qui ne lui permet pas de surveiller les obstacles qui se trouvent dans son dos.Conventionally, a lifting platform comprises a motorized chassis, wheels, a telescopic mast hinged to the frame and a mobile platform where can be held an operator, arranged at the end of the telescopic mast. The platform has a control station allowing the operator to control the movement of the platform. When the operator is installed at the control station, he is usually turned towards the telescopic mast, which does not allow him to monitor the obstacles on his back.

Il arrive fréquemment que lorsque l'opérateur déplace la plateforme, il soit percuté par l'arrière par un obstacle. L'opérateur est alors poussé contre le poste de commande, ce qui l'empêche de stopper le mouvement de la plateforme.It often happens that when the operator moves the platform, it is hit by the rear by an obstacle. The operator is then pushed against the control station, which prevents it from stopping the movement of the platform.

Pour empêcher ces accidents, il est connu d'équiper la plateforme de dispositifs qui détectent un risque de collision entre l'opérateur et le poste de pilotage. Par exemple, de tels dispositifs de détection comprennent des radars ou des caméras. Toutefois, ces dispositifs sont difficiles à régler pour être efficaces dans des environnements à géométrie complexe, tels que les charpentes métalliques en construction, car il est nécessaire de distinguer les obstacles dangereux et les objets sur lesquels l'opérateur travaille. Il est notamment nécessaire de désactiver les capteurs lorsque l'opérateur se positionne à proximité d'un objet sur lequel il doit effectuer une tâche.To prevent these accidents, it is known to equip the platform with devices that detect a risk of collision between the operator and the cockpit. For example, such detection devices include radars or cameras. However, these devices are difficult to adjust to be effective in complex geometry environments, such as metal frames under construction, because it is necessary to distinguish between dangerous obstacles and objects on which the operator works. In particular, it is necessary to deactivate the sensors when the operator is positioned near an object on which he must perform a task.

JP 2009 084033 A divulge une plateforme de nacelle élévatrice, comprenant un poste de pilotage, un plancher comportant une zone de positionnement d'un opérateur manoeuvrant le poste de pilotage un garde-corps fixé sur un pourtour du plancher et un dispositif de protection situé sur une face du garde-corps; la zone et le dispositif de protection s'étendant chacun de part et d'autre d'un plan perpendiculaire à la face du garde-corps. JP 2009 084033 A discloses a platform of aerial platform, comprising a cockpit, a floor having a positioning area of an operator operating the cockpit a railing fixed on a perimeter of the floor and a protective device located on a face of the guard -body; the zone and the protective device each extending on either side of a plane perpendicular to the face of the guardrail.

KR-20-2012-0 006 585 divulgue une plateforme de nacelle élévatrice équipée d'un capteur se présentant sous la forme d'une tige positionnée dans un coin de la plateforme et s'étendant en hauteur par rapport à un garde-corps de la plateforme. Lorsque la tige entre en contact avec un obstacle, le mouvement de la plateforme est stoppé automatiquement. L'efficacité de ce système de protection est limitée car la tige détecte uniquement les obstacles qu'elle rencontre lors d'un mouvement ascendant de la plateforme, ce qui ne protège pas l'opérateur des obstacles qui se présentent latéralement. KR-20-2012-0 006 585 discloses a platform lift equipped with a sensor in the form of a rod positioned in a corner of the platform and extending in height relative to a railing of the platform. When the rod comes in contact with an obstacle, the movement of the platform is stopped automatically. The effectiveness of this protection system is limited because the rod only detects the obstacles it encounters during an upward movement of the platform, which does not protect the operator from the obstacles that present themselves laterally.

JP 2002-503 632 divulgue une plateforme de nacelle élévatrice équipée d'un dispositif de sécurité prévu pour protéger l'utilisateur des dangers électriques. La structure relativement légère de ces dispositifs de sécurité les rend fragiles, ce qui ne permet pas de protéger l'opérateur contre les collisions et les risques d'écrasement. En outre, les dispositifs de sécurité ont une géométrie qui obstrue la vision de l'opérateur se tenant sur la plateforme. Il est donc prévu d'escamoter le dispositif de sécurité lors du déplacement de la plateforme, et de lever le dispositif de sécurité dans une position de protection lorsque la plateforme est à l'arrêt et que l'opérateur souhaite travailler. Ainsi, en déplacement, le dispositif de sécurité ne protège pas l'opérateur contre les collisions et les risques d'écrasement. Aucun moyen n'est prévu pour contraindre l'opérateur de lever le dispositif de protection lorsqu'il entre dans la plateforme. JP 2002-503,632 discloses a platform of aerial platform equipped with a safety device provided to protect the user from electrical hazards. The relatively light structure of these safety devices makes them fragile, which does not protect the operator against collisions and the risk of crushing. In addition, the safety devices have a geometry that obstructs the vision of the operator standing on the platform. It is therefore planned to retract the safety device when moving of the platform, and lift the safety device in a protective position when the platform is stopped and the operator wishes to work. Thus, on the move, the safety device does not protect the operator against collisions and the risk of crushing. No means is provided to force the operator to lift the guard when entering the platform.

Le but de la présente invention est de proposer une plateforme de nacelle élévatrice équipée d'un système de protection efficace pour empêcher la collision entre les obstacles et l'opérateur manoeuvrant la plateforme.The object of the present invention is to provide a lifting platform platform equipped with an effective protection system to prevent collision between the obstacles and the operator operating the platform.

A cet effet, l'invention a pour objet une plateforme de nacelle élévatrice, comprenant :

  • un poste de pilotage,
  • un plancher comportant une zone de positionnement d'un opérateur manoeuvrant le poste de pilotage,
  • un garde-corps fixé sur un pourtour du plancher.
  • un dispositif de protection situé sur une face du garde-corps. La zone et le dispositif de protection s'étendent chacun de part et d'autre d'un plan perpendiculaire à la première face du garde-corps. Une largeur du dispositif de protection, mesurée perpendiculairement au plan est supérieure à 30 cm, de préférence supérieure à 60 cm. Le dispositif de protection est mobile entre une position escamotée, dans laquelle une hauteur de dépassement du dispositif de protection par rapport au garde-corps, mesuré perpendiculairement au plancher, a une valeur inférieure à 10 cm, de préférence inférieure à 1 cm et une position de protection, dans laquelle le dépassement a une valeur supérieure à 30 cm, de préférence supérieure à 45 cm. Le garde-corps comporte une ouverture d'accès à la plateforme, apte à être obstruée au moins partiellement par des moyens de fermeture. L'accès de l'opérateur à la plateforme, à travers l'ouverture, nécessite de positionner le dispositif de protection dans la position de protection.
For this purpose, the subject of the invention is a platform of aerial platform, comprising:
  • a cockpit,
  • a floor including a positioning zone of an operator operating the cockpit,
  • a guardrail fixed on a perimeter of the floor.
  • a protective device located on one side of the guardrail. The zone and the protective device each extend on either side of a plane perpendicular to the first face of the railing. A width of the protective device, measured perpendicular to the plane is greater than 30 cm, preferably greater than 60 cm. The protective device is movable between a retracted position, in which a height of protrusion of the protective device relative to the railing, measured perpendicular to the floor, has a value less than 10 cm, preferably less than 1 cm and a position in which the excess is greater than 30 cm, preferably greater than 45 cm. The railing has an access opening to the platform, which can be at least partially obstructed by closure means. Access of the operator to the platform, through the opening, requires positioning the protective device in the protective position.

Grâce à l'invention, le dispositif de protection assure une protection mécanique de l'opérateur en s'opposant à la collision entre un obstacle et le dos d'un opérateur pilotant le poste de commande de la nacelle élévatrice. Le dispositif de protection est escamotable, ce qui permet de le désactiver lorsqu'il gêne l'opérateur pour effectuer une tâche.Thanks to the invention, the protective device provides mechanical protection of the operator by opposing the collision between an obstacle and the back of an operator driving the control station of the aerial platform. The protection device is retractable, which allows it to be deactivated when it hinders the operator to perform a task.

La figure 1 représente un véhicule 1 de type nacelle élévatrice de personnel conforme à l'invention. La nacelle 1 comprend un châssis motorisé 2 qui repose sur la surface du sol par quatre roues 3A, 3B, 3C et 3D. A la place de roues, le châssis 2 peut être équipé de chenilles formant d'autres types d'organes de liaison au sol.The figure 1 represents a vehicle 1 liftsaver type of vehicle according to the invention. The nacelle 1 comprises a motorized chassis 2 which rests on the surface of the ground by four wheels 3A, 3B, 3C and 3D. Instead of wheels, the chassis 2 can be equipped with tracks forming other types of ground connection members.

Sur le châssis 2 est montée une embase 5 sur laquelle est articulé un mât télescopique 6. Le mât 6 est télescopique dans ce sens qu'il comprend un fût 61 articulé sur l'embase 5 et une partie 62 adaptée pour coulisser à l'intérieur du fût 61 en étant commandée par un vérin hydraulique.On the chassis 2 is mounted a base 5 on which is articulated a telescopic mast 6. The mast 6 is telescopic in that it comprises a shaft 61 articulated on the base 5 and a portion 62 adapted to slide inside barrel 61 being controlled by a hydraulic cylinder.

L'extrémité supérieure de la partie 62 du mât, c'est-à-dire son extrémité la plus éloignée du fût 61, est pourvue d'un étrier 621 d'accrochage d'une structure à parallélogramme 64 sur laquelle est suspendue une plateforme 7 où peut se tenir un opérateur ou sur laquelle on peut disposer des charges à transporter en hauteur.The upper end of the portion 62 of the mast, that is to say the end farthest from the barrel 61, is provided with a stirrup 621 for hooking a parallelogram structure 64 on which is suspended a platform 7 where can be held an operator or on which one can dispose of the loads to be transported in height.

La plateforme 7 comprend un plancher 71 sur lequel reposent les pieds de l'opérateur. Le plancher 71 est de forme globalement rectangulaire et comporte deux bords longs 71 A et 71 B opposés et parallèles, ainsi que deux bords courts 71C et 71 D perpendiculaires aux bords longs 71 A et 71 B. Une plinthe 73 entoure le pourtour du plancher 71, qui est formé par les bords 71 A à 71 D.The platform 7 comprises a floor 71 on which the feet of the operator rest. The floor 71 is of generally rectangular shape and has two long edges 71A and 71B opposite and parallel, and two short edges 71C and 71D perpendicular to the long edges 71A and 71B. A skirting 73 surrounds the perimeter of the floor 71 which is formed by the edges 71 A to 71 D.

Un garde corps 72 formant une barrière de protection est fixé sur le pourtour 71 A à 71 D du plancher 71. Le garde-corps 72 comprend des montants verticaux 721 et horizontaux 722 qui forment des faces 72A, 72B, 72C et 72D du garde-corps 72, perpendiculaires au plancher 71. Les faces 72A à 72D du garde-corps 72 sont attenantes respectivement aux bords 71 A à 71 D du plancher 71. Les faces 72A et 72B sont opposées et parallèles entre elles ; les faces 72C et 72D sont perpendiculaires aux faces 72A et 72B.A guard 72 forming a protective barrier is fixed on the perimeter 71 A to 71 D of the floor 71. The railing 72 comprises vertical uprights 721 and horizontal 722 which form faces 72A, 72B, 72C and 72D of the guard. body 72, perpendicular to the floor 71. The faces 72A to 72D of the railing 72 are respectively adjacent to the edges 71 A to 71 D of the floor 71. The faces 72A and 72B are opposite and parallel to each other; the faces 72C and 72D are perpendicular to the faces 72A and 72B.

Un poste de pilotage 8 est situé sur la première face 72A du garde-corps 72, qui est fixée à la structure parallélogramme 63. Le poste de pilotage 8 permet à un opérateur qui se trouve sur la plateforme 7 de commander le mouvement de la plateforme 7 par rapport au châssis 2 de la nacelle élévatrice 1, en déplaçant la partie 62 par rapport au fût 61 et en modifiant la géométrie de la structure à parallélogramme 63..A cockpit 8 is located on the first face 72A of the railing 72, which is fixed to the parallelogram structure 63. The cockpit 8 allows an operator on the platform 7 to control the movement of the platform 7 relative to the chassis 2 of the aerial platform 1, by moving the portion 62 relative to the shaft 61 and by modifying the geometry of the parallelogram structure 63.

Une ouverture 724 d'accès à la plateforme est ménagée dans la deuxième face 72B, à l'opposé du poste de pilotage 8. L'ouverture d'accès 724 est délimitée en bas par la plinthe 73, au niveau du bord 71 A du plancher 71, et sur les côtés par deux montants verticaux 721 du garde-corps 72. L'ouverture d'accès 724 permet à un opérateur d'entrer à l'intérieur du garde-corps 72 pour s'installer sur la plateforme 7.An opening 724 to access the platform is formed in the second face 72B, opposite the cockpit 8. The access opening 724 is bounded below by the skirting 73, at the edge 71 A of the floor 71, and on the sides by two uprights 72. The access opening 724 allows an operator to enter the guardrail 72 to settle on the platform 7.

On note P1 un plan perpendiculaire au plancher 71 et aux faces 72A et 72B du garde-corps 72, ce plan étant équidistant des faces 72C et 72D. Le poste de pilotage 8 et l'ouverture d'accès 724 sont situés chacun de part et d'autre du plan P1, en étant centrés chacun sur ce plan.P1 is a plane perpendicular to the floor 71 and the faces 72A and 72B of the guard rail 72, this plane being equidistant from the faces 72C and 72D. The cockpit 8 and the access opening 724 are each located on either side of the plane P1, each centered on this plane.

Un dispositif de protection 9 est situé sur la première face 72A du garde-corps 72. Le dispositif de protection 9 comprend une structure mécanique formée par un arceau rigide métallique globalement en forme de U, qui comprend deux montants verticaux 91 et 92 et un montant horizontal 93. Les montants verticaux 91 et 92 sont disposés contre les montants verticaux 721 qui délimitent l'ouverture 724.A protection device 9 is located on the first face 72A of the railing 72. The protection device 9 comprises a mechanical structure formed by a generally U-shaped metal rigid hoop, which comprises two vertical uprights 91 and 92 and an upright horizontal 93. The uprights 91 and 92 are arranged against the uprights 721 which define the opening 724.

Le dispositif de protection 9 est mobile en translation, selon une direction globalement perpendiculaire au plancher 71, par rapport au garde-corps 72 et au plancher 71, comme représenté par la flèche F à la figure 2. Le dispositif de protection 9 est mobile entre une position escamotée, représentée aux figures 1 et 2, et une position de protection, représentée à la figure 3.The protective device 9 is movable in translation, in a direction generally perpendicular to the floor 71, with respect to the railing 72 and the floor 71, as represented by the arrow F at the figure 2 . The protective device 9 is movable between a retracted position, represented in FIGS. figures 1 and 2 , and a protective position, shown in figure 3 .

On note D la hauteur de dépassement du dispositif de protection 9 par rapport au garde-corps 72, mesuré perpendiculairement au plancher 71. La hauteur de dépassement D est mesurée entre la zone du dispositif de protection 9 la plus éloignée du plancher 71, et la zone du garde-corps 72 la plus éloignée du plancher 71. Dans le cas d'espèce, la zone du dispositif de protection 9 la plus éloignée du plancher 71 est formée par une face supérieure 931 du montant horizontal 93 du dispositif de protection 9, tournée à l'opposé du plancher 71. La zone du garde-corps 72 la plus éloignée du plancher 71 est formée par les montants horizontaux 722 du garde-corps 72 les plus éloignés du plancher 7.D is the height of protector 9 protruding from railing 72, measured perpendicularly to floor 71. The overtopping height D is measured between the area of protection device 9 furthest from floor 71, and the the zone of the railing 72 farthest from the floor 71. In the case in point, the area of the protection device 9 furthest from the floor 71 is formed by an upper face 931 of the horizontal upright 93 of the protection device 9, turned away from the floor 71. The area of the railing 72 farthest from the floor 71 is formed by the horizontal posts 722 of the railing 72 farthest from the floor 7.

Dans la position escamotée, la hauteur de dépassement D a une première valeur D1 inférieure à 10 cm, de préférence inférieure à 1 cm. Dans l'exemple représenté aux figures 1 et 2, la première valeur D1 est nulle. En d'autres termes, le dispositif de protection 9 affleure le bord supérieur du garde-corps 72.In the retracted position, the overflow height D has a first value D1 of less than 10 cm, preferably less than 1 cm. In the example shown in figures 1 and 2 , the first value D1 is zero. In other words, the protection device 9 is flush with the upper edge of the guard rail 72.

Dans la position de protection, la hauteur de dépassement a une deuxième valeur D2 supérieure à 30 cm, de préférence supérieure à 45 cm.In the protection position, the overtaking height has a second value D2 greater than 30 cm, preferably greater than 45 cm.

Généralement, la hauteur du garde-corps 72 est comprise entre 1 m et 1,10 m. Ainsi, dans la position de protection, la hauteur du dispositif de protection, mesurée à partir du plancher 71, est comprise supérieure à 1,30 m, de préférence supérieure à 1,55 m.Generally, the height of the railing 72 is between 1 m and 1.10 m. Thus, in the protective position, the height of the protection device, measured from the floor 71, is greater than 1.30 m, preferably greater than 1.55 m.

Des moyens de fermeture 4 comprenant deux battants 41 et 42 obstruent partiellement l'ouverture d'accès 724. Les battants 41 et 42 sont articulés chacun sur l'un des montants verticaux 91 et 92 du dispositif de protection 9, entre une position fermée, représentée aux figures 1 à 3, et une position ouverte, non visible sur les figures. Dans la position fermée, les battants 41 et 42 se situent dans le plan de l'ouverture d'accès 724. Dans la position ouverte, les battants 41 et 42 n'obstruent pas l'ouverture d'accès 724.Closing means 4 comprising two leaves 41 and 42 partially obstruct the access opening 724. The leaves 41 and 42 are each hinged on one vertical uprights 91 and 92 of the protection device 9, between a closed position, shown in FIGS. Figures 1 to 3 , and an open position, not visible in the figures. In the closed position, the leaves 41 and 42 are in the plane of the access opening 724. In the open position, the leaves 41 and 42 do not obstruct the access opening 724.

Des moyens de verrouillage 10 permettent de verrouiller les moyens de fermeture 4.Locking means 10 make it possible to lock the closing means 4.

Les moyens de verrouillage 10 comprennent un rail 102, ayant une section transversale globalement en forme de U, visible à la figure 2 grâce à un arrachement partiel de la plinthe 93. Le rail 102 est fixé sur le plancher 71, en dessous des battants 41 et 42. Lorsque les moyens de fermeture 4 sont en position fermée et lorsque le dispositif de protection 9 est dans la position escamotée, le bord inférieur des battants 41 et 42 est logé dans le rail 102, qui bloque l'ouverture des battants 41 et 42. Ainsi,The locking means 10 comprise a rail 102, having a generally U-shaped cross section, visible at the figure 2 thanks to a partial tearing of the baseboard 93. The rail 102 is fixed on the floor 71, below the leaves 41 and 42. When the closing means 4 are in the closed position and when the protective device 9 is in the retracted position , the lower edge of the leaves 41 and 42 is housed in the rail 102, which blocks the opening of the leaves 41 and 42. Thus,

Les moyens de verrouillage 10 comprennent également deux doigts 104A et 104B qui permettent de verrouiller le dispositif de protection 9 dans la position escamotée et dans la position de protection, en coopérant avec des trous, non visibles sur les figures, ménagés dans les montants verticaux 721 du garde-corps 72 qui bordent l'ouverture d'accès 724.The locking means 10 also comprise two fingers 104A and 104B which make it possible to lock the protection device 9 in the retracted position and in the protective position, by cooperating with holes, not visible in the figures, formed in the vertical uprights 721. of the guard rail 72 which border the access opening 724.

Les moyens de verrouillage 10 sont mobiles entre une position verrouillée, dans laquelle les doigts 104A et 104B sont logés dans les trous, et une position déverrouillée, dans laquelle les doigts 104A et 104B sont à l'extérieur des trous. Lorsque les moyens de verrouillage 10 sont verrouillés, la translation du dispositif de protection 9 est bloquée, de sorte que le dispositif de protection ne peut pas être déplacé par l'opérateur entre la position escamotée et la position de protection, ou inversement.The locking means 10 are movable between a locked position, in which the fingers 104A and 104B are housed in the holes, and an unlocked position, in which the fingers 104A and 104B are outside the holes. When the locking means 10 are locked, the translation of the protective device 9 is blocked, so that the protective device can not be moved by the operator between the retracted position and the protective position, or vice versa.

La position des moyens de verrouillage 10 est commandée par des moyens de commande 13 comprenant deux poignées fixées chacune à l'un des battants 41 et 42, et deux câbles reliant chaque poignée à l'un des doigts 104A et 104B. Les moyens de commande 13 sont mobiles entre une position de repos, dans laquelle aucune action n'est exercée sur les poignées et dans laquelle les doigts 104A et 104B sont logés dans les trous, et une position activée, dans laquelle l'opérateur actionne les poignées de manière à extraire les doigts 104A et 104B des trous.The position of the locking means 10 is controlled by control means 13 comprising two handles each attached to one of the leaves 41 and 42, and two cables connecting each handle to one of the fingers 104A and 104B. The control means 13 are movable between a rest position, in which no action is exerted on the handles and in which the fingers 104A and 104B are housed in the holes, and an activated position, in which the operator actuates the handles to extract the fingers 104A and 104B from the holes.

Les moyens de verrouillage 10 sont verrouillés par défaut. Lorsqu'aucune action n'est exercée sur les moyens de commande 13, les moyens de verrouillage 10 sont verrouillés et s'opposent au déplacement du dispositif de protection 9.The locking means 10 are locked by default. When no action is exerted on the control means 13, the locking means 10 are locked and oppose the movement of the protection device 9.

Le fonctionnement du dispositif de protection 9 est le suivant : le dispositif de protection 9 est initialement dans la position escamotée, représentée aux figures 1 et 2, avec les moyens de fermeture 4 dans la position fermée. Le rail 102 bloque l'ouverture des moyens de fermeture 4, de sorte que l'opérateur ne peut pas pousser les battants 41 et 42. De plus, tant que l'opérateur n'agit pas sur les moyens de commande 13, le dispositif de protection 9 est bloqué dans la position escamotée car les doigts 104A et 104B sont logés dans les trous. L'opérateur ne peut donc pas soulever le dispositif de protection 9 s'il essaye de saisir le montant horizontal 93 pour le soulever, comme indiqué par la flèche F. Ainsi, les moyens de fermeture 4 bloquent l'ouverture d'accès 724 tant que le dispositif de protection 9 est dans la position escamotée.The operation of the protection device 9 is as follows: the protection device 9 is initially in the retracted position, represented in FIGS. figures 1 and 2 , with the closing means 4 in the closed position. The rail 102 blocks the opening closing means 4, so that the operator can not push the wings 41 and 42. Moreover, as long as the operator does not act on the control means 13, the protection device 9 is blocked in the position retracted because the fingers 104A and 104B are housed in the holes. The operator can not lift the protection device 9 if he tries to grab the horizontal post 93 to lift it, as indicated by the arrow F. Thus, the closing means 4 block the access opening 724 as that the protection device 9 is in the retracted position.

Pour pouvoir libérer l'ouverture d'accès 724 et entrer à l'intérieur du garde-corps 72, l'opérateur doit actionner les moyens de commande 13 afin de déverrouiller les moyens de verrouillage 10. Compte tenu de la disposition des moyens de commande 13, lorsque l'opérateur actionne les moyens de commande 13, sa main entoure une partie de chaque battant 41 et 42. Une fois les moyens de verrouillage 10 déverrouillés, l'opérateur peut soulever le dispositif de protection 9 pour l'amener dans la position de protection et peut ouvrir les moyens de fermeture 4 pour entrer dans la plateforme 4 puisque le rail 102 ne bloque plus le mouvement des battants 41 et 42.In order to be able to release the access opening 724 and to enter the interior of the railing 72, the operator must actuate the control means 13 in order to unlock the locking means 10. Given the arrangement of the control means 13, when the operator actuates the control means 13, his hand surrounds a portion of each leaf 41 and 42. Once the locking means 10 are unlocked, the operator can lift the protection device 9 to bring it into the door. protection position and can open the closing means 4 to enter the platform 4 since the rail 102 no longer blocks the movement of the leaves 41 and 42.

Lorsque le dispositif de protection 9 est dans la position de protection et que l'opérateur arrête d'agir sur les moyens de commande 13, les moyens de verrouillage 10 retournent dans leur position verrouillée ce qui verrouille le dispositif de protection 9 dans la position de protection.When the protective device 9 is in the protective position and the operator stops acting on the control means 13, the locking means 10 return to their locked position which locks the protection device 9 in the position of protection.

Dans la position de protection, l'arceau 91, 92 et 93 du dispositif de protection 9 forme une protection mécanique de l'opérateur. En effet, lorsqu'un obstacle arrive dans le dos de l'opérateur, il est arrêté ou freiné par le dispositif de protection 9 qui stoppe l'obstacle et protège l'opérateur des collisions.In the protective position, the hoop 91, 92 and 93 of the protection device 9 forms a mechanical protection of the operator. Indeed, when an obstacle arrives in the back of the operator, it is stopped or braked by the protective device 9 which stops the obstacle and protects the operator from collisions.

On note L9 une largeur du dispositif de protection 9, mesurée perpendiculairement au plan P1. La largeur L9 correspond à la longueur du montant horizontal 93 et à l'espacement des montants verticaux 91 et 92. La largeur L9 est supérieure à 30 cm, de préférence supérieure à 60 cm. La largeur L9 correspond globalement à la largeur des épaules d'un opérateur, de manière à assurer de manière efficace sa protection.We denote L9 a width of the protection device 9, measured perpendicularly to the plane P1. The width L9 corresponds to the length of the horizontal upright 93 and to the spacing of the vertical uprights 91 and 92. The width L9 is greater than 30 cm, preferably greater than 60 cm. The width L9 broadly corresponds to the width of the shoulders of an operator, so as to ensure its effective protection.

Comme visible à la figure 7, lorsque le dispositif de protection 9 est dans la position de protection, il est mobile en rotation par rapport au garde-corps 72, autour d'un axe X1 perpendiculaire au plan P1, comme représenté par la flèche R. Une butée mécanique 11 permettent de stopper le mouvement du dispositif de protection 9, lorsqu'il est percuté par un obstacle par l'arrière. Des premiers moyens de détection, par exemple un palpeur, permettent de détecter lorsque le dispositif de protection 9 vient en contact avec la butée mécanique 11. Une unité électronique de la nacelle élévatrice 1, par exemple intégrée au poste de pilotage 8, est programmée pour stopper automatiquement tout mouvement de la plateforme 7 lorsque le dispositif de protection 9 active les moyens de détection. De cette manière, la sécurité de l'opérateur est renforcée.As visible at figure 7 when the protection device 9 is in the protective position, it is rotatable relative to the railing 72, around an axis X1 perpendicular to the plane P1, as represented by the arrow R. A mechanical stop 11 allow to stop the movement of the protection device 9, when it is hit by an obstacle from the rear. First detection means, for example a probe, make it possible to detect when the protective device 9 comes into contact with the mechanical stop 11. An electronic unit of the aerial platform 1, for example integrated in the cockpit 8, is programmed to stop automatically any movement of the platform 7 when the protection device 9 activates the detection means. In this way, the safety of the operator is enhanced.

Pour pouvoir baisser le dispositif de protection 9 dans la position escamotée, l'opérateur doit agir sur les moyens de commande 13, de manière à déverrouiller les moyens de verrouillage 10. Cela permet d'améliorer la sécurité de la nacelle élévatrice 1 car le dispositif de protection reste par défaut dans la position de protection, une fois que l'opérateur l'a déplacé dans cette position.To be able to lower the protection device 9 in the retracted position, the operator must act on the control means 13, so as to unlock the locking means 10. This improves the safety of the aerial platform 1 because the device protection remains in the protection position, once the operator has moved to this position.

En effet, les moyens de verrouillage 10 verrouillent automatiquement le dispositif de protection 9 en position escamotée, sans nécessiter d'action supplémentaire de la part de l'opérateur, lorsque le dispositif de protection 9 passe de la position escamotée à la position de protection.Indeed, the locking means 10 automatically lock the protective device 9 in the retracted position, without requiring additional action on the part of the operator, when the protective device 9 passes from the retracted position to the protective position.

Lorsque l'opérateur souhaite baisser le dispositif de protection 9 dans la position escamotée, par exemple lorsque le dispositif de protection 9 le gêne pour effectuer une tâche, il doit agir sur les moyens de commande 13 afin de déverrouiller les moyens de verrouillage 10, ce qui lui permet de baisser le dispositif de protection 9 dans la position escamotée.When the operator wishes to lower the protective device 9 in the retracted position, for example when the protection device 9 hinders him to perform a task, he must act on the control means 13 to unlock the locking means 10, this which allows him to lower the protection device 9 in the retracted position.

La plateforme comprend des seconds moyens de détection, non représentés, qui détectent dans quelle position se trouve le dispositif de protection 9. Le poste de pilotage 8 comprend des moyens d'indication 12, tels qu'une diode lumineuse, reliés aux seconds moyens de détection. Les moyens d'indication 12 indiquent visuellement à l'opérateur dans quelle position se trouve le dispositif de protection 9, ce qui permet d'améliorer la sécurité en indiquant à l'opérateur lorsque le dispositif de protection 9 est dans la position escamotée et ne le protège pas. Ceci est particulièrement utile car lorsque l'opérateur utilise le poste de commande 8, il tourne le dos au dispositif de sécurité 9.The platform comprises second detection means, not shown, which detect in which position the protection device 9 is located. The cockpit 8 comprises indication means 12, such as a light diode, connected to the second means of detection. The indicating means 12 visually indicate to the operator in which position the protection device 9 is located, which makes it possible to improve the safety by indicating to the operator when the protection device 9 is in the retracted position and does not do not protect him. This is particularly useful because when the operator uses the control station 8, he turns his back on the security device 9.

Les figures 4 et 5 montrent une plateforme 1007 conforme à un deuxième mode de réalisation de l'invention. Dans la suite, les éléments de la plateforme 1007 semblables à ceux de la plateforme 7 portent les mêmes références numériques.The figures 4 and 5 show a platform 1007 according to a second embodiment of the invention. In the following, platform elements 1007 similar to those of platform 7 have the same numerical references.

La plateforme 1007 fait partie d'une nacelle élévatrice analogue à celle de la figure 1. La plateforme 1007 comprend un plancher 71, un garde-corps 72 comportant une ouverture d'accès 724, une plinthe 73 et un poste de pilotage 8. Ces éléments sont semblables à ceux de la plateforme 7 et on ne les décrit pas en détail par la suite.The 1007 platform is part of an aerial work platform similar to that of the figure 1 . The platform 1007 includes a floor 71, a railing 72 having an access opening 724, a skirting 73 and a cockpit 8. These elements are similar to those of the platform 7 and are not described in detail by the following.

La nacelle 1007 comprend un dispositif de protection 1009 situé sur une face 72B du garde-corps 72 opposée à la face 72A le long de laquelle est situé le poste de pilotage 8. Le dispositif de protection 1009 comprend un arceau rigide métallique globalement en forme de U, qui comprend deux montants verticaux 1091 et 1092 et un montant horizontal 1093. Le dispositif de protection 1009 comprend également un montant transversal 1094 qui relie les montants verticaux 1091 et 1092.The nacelle 1007 comprises a protection device 1009 located on a face 72B of the railing 72 opposite the face 72A along which is located the cockpit 8. The protection device 1009 comprises a metal rigid hoop generally shaped U, which comprises two vertical uprights 1091 and 1092 and a horizontal upright 1093. The protective device 1009 also includes a transverse post 1094 which connects the uprights 1091 and 1092.

Le dispositif de protection 1009 est mobile en translation, selon une direction globalement perpendiculaire au plancher 71, par rapport au garde-corps 72 et au plancher 71. Le dispositif de protection 1009 est mobile entre une position escamotée, représentée à la figure 4, et une position de protection, représentée à la figure 5.The protective device 1009 is movable in translation, in a direction generally perpendicular to the floor 71, relative to the railing 72 and the floor 71. The protection device 1009 is movable between a retracted position, shown in FIG. figure 4 , and a protective position, shown in figure 5 .

Dans la position escamotée, une hauteur de dépassement D du dispositif de protection 1009 par rapport au garde-corps 72 prend une première valeur D1001, inférieure à 10 cm, de préférence inférieure à 1 cm. Dans l'exemple représenté à la figure 4, la première valeur D1001 est nulle. En d'autres termes, le dispositif de protection 1009 affleure le bord supérieur du garde-corps 72.In the retracted position, an overflow height D of the protection device 1009 with respect to the railing 72 takes a first value D1001, less than 10 cm, preferably less than 1 cm. In the example shown in figure 4 , the first value D1001 is zero. In other words, the protection device 1009 is flush with the upper edge of the guard rail 72.

Dans la position de protection, la hauteur de dépassement prend une deuxième valeur D1002 supérieure à 30 cm, de préférence supérieure à 45 cm.In the protection position, the excess height takes a second value D1002 greater than 30 cm, preferably greater than 45 cm.

Lorsque le dispositif de protection 1009 est dans la position de protection, il est mobile en rotation par rapport au garde-corps 72, autour d'un axe X1 perpendiculaire au plan P1. Des premiers moyens de détection comprenant une butée mécanique 1011 permettent de détecter lorsque le dispositif de protection 9 vient en contact avec la butée mécanique 1011, ce qui survient lorsqu'un obstacle 101 percute le dispositif de protection 1009. Une unité électronique de la nacelle élévatrice 1, par exemple intégrée au poste de pilotage 8, est programmée pour stopper automatiquement tout mouvement de la plateforme 1007 lorsque le dispositif de protection 1009 active les moyens de détection. De cette manière, la sécurité de l'opérateur est renforcée.When the protection device 1009 is in the protective position, it is rotatable relative to the railing 72 about an axis X1 perpendicular to the plane P1. First detection means comprising a mechanical stop 1011 can detect when the protective device 9 comes into contact with the mechanical stop 1011, which occurs when an obstacle 101 collides with the protection device 1009. An electronic unit of the aerial platform 1, for example integrated in the cockpit 8, is programmed to automatically stop any movement of the platform 1007 when the protection device 1009 activates the detection means. In this way, the safety of the operator is enhanced.

Des moyens de fermeture 1004 comprenant une barre transversale 1041 obstruent partiellement l'ouverture d'accès 724. La barre transversale 1041 est reliée aux montants verticaux 721 du garde-corps 72 délimitant l'ouverture d'accès 724, au moyen d'étriers 1042 et 1043 qui encerclent chacun l'un des montants verticaux 721. La barre transversale 1041 est retenue globalement à mi-hauteur de l'ouverture d'accès 724 par des montants horizontaux 722 du garde-corps 72.Closing means 1004 comprising a transverse bar 1041 partially obstruct the access opening 724. The transverse bar 1041 is connected to the vertical uprights 721 of the railing 72 delimiting the access opening 724 by means of stirrups 1042. and 1043 which each encircle one of the uprights 721. The cross bar 1041 is retained generally at mid-height of the access opening 724 by horizontal uprights 722 of the guard rail 72.

Les moyens de fermeture 1004 sont mobiles en translation, le long d'une direction perpendiculaire au plancher 71, entre une position fermée, représentée aux figures 4 et 5, et une position ouverte, non représentée. Dans la position fermée, la barre transversale 1041 est située globalement à mi-hauteur de l'ouverture d'accès 724. Dans la position ouverte, la barre transversale 1041 est située en partie supérieure de l'ouverture d'accès 724 à proximité du montant transversal 1094, de sorte que l'opérateur peut franchir l'ouverture d'accès 724 en passant sous les éléments 1041 et 1094.The closure means 1004 are movable in translation, along a direction perpendicular to the floor 71, between a closed position, shown in FIGS. figures 4 and 5 , and an open position, not shown. In the closed position, the transverse bar 1041 is located generally halfway up the access opening 724. In the open position, the transverse bar 1041 is located in the upper part of the access opening 724 near the transverse amount 1094, so that the operator can cross the access opening 724 passing under the elements 1041 and 1094.

Des moyens de verrouillage 1010 permettent de verrouiller simultanément les moyens de fermeture 4 et le dispositif de protection 9.Locking means 1010 make it possible to simultaneously lock the closing means 4 and the protection device 9.

Les moyens de verrouillage 1010 comprennent deux doigts 1104A et 1104B, visibles à la figure 6, qui permettent de verrouiller le dispositif de protection 1009 dans la position escamotée et dans la position de protection.The locking means 1010 comprise two fingers 1104A and 1104B, visible to the figure 6 , which make it possible to lock the protection device 1009 in the retracted position and in the protection position.

Le premier doigt 1104A est situé au niveau du montant 1091 du dispositif de protection 1009 et est apte à pénétrer, lorsque le dispositif de protection 1009 est dans la position escamotée, dans un premier trou 1140A formé par une ouverture ménagée dans le montant vertical 1091 et par une ouverture ménagée dans le garde-corps 72.The first finger 1104A is located at the level 1091 of the protection device 1009 and is able to penetrate, when the protection device 1009 is in the retracted position, in a first hole 1140A formed by an opening in the vertical post 1091 and by an opening in the guard rail 72.

Le premier doigt 1104A est également apte à pénétrer, lorsque le dispositif de protection 1009 est dans la position de protection, dans un deuxième trou 1140'A qui est plus éloigné du plancher 71 que le premier trou 1140A.The first finger 1104A is also able to penetrate, when the protection device 1009 is in the protective position, in a second hole 1140'A which is further away from the floor 71 than the first hole 1140A.

Le deuxième doigt 1104B est situé au niveau du montant 1092 du dispositif de protection 1009 et est apte à pénétrer, lorsque le dispositif de protection 1009 est dans la position escamotée, dans un troisième trou 1140B formé par une ouverture ménagée dans le montant vertical 1092 et par une ouverture ménagée dans le garde-corps 72.The second finger 1104B is located at the upright 1092 of the protection device 1009 and is capable of penetrating, when the protection device 1009 is in the retracted position, into a third hole 1140B formed by an opening in the vertical upright 1092 and by an opening in the guard rail 72.

Le deuxième doigt 1104B est également apte à pénétrer, lorsque le dispositif de protection 1009 est dans la position de protection, dans un quatrième trou 1140'B ménagé dans le montant vertical 92 et dans le garde-corps 72. Le quatrième trou 1140'B est plus éloigné du plancher 71 que le troisième trou 1140B et il est aligné horizontalement avec le deuxième trou 1140'A.The second finger 1104B is also able to penetrate, when the protection device 1009 is in the protective position, into a fourth hole 1140'B formed in the vertical upright 92 and in the guard rail 72. The fourth hole 1140'B is further away from the floor 71 than the third hole 1140B and is aligned horizontally with the second hole 1140'A.

Les moyens de verrouillage 1010 sont mobiles entre une position verrouillée, laquelle les doigts 1104A et 1104B, sont logés dans les trous 1140A et 1140B, ou 1140'A et 1140'B, et une position déverrouillée, laquelle les doigts 1104A et 1104B sont à l'extérieur des trous 1104A et 1104B, ou 1104'A et 1104'B. Lorsque les moyens de verrouillage 1010 sont verrouillés, la translation des moyens de fermeture 1004 est bloquée, de sorte que les moyens de fermeture 4 ne peuvent pas être ouverts ou fermés par l'opérateur, et la translation du dispositif de protection 1009 est bloquée, de sorte que le dispositif de protection 9 ne peut pas être déplacé par l'opérateur entre la position escamotée et la position de protection, ou inversement.The locking means 1010 are movable between a locked position, which the fingers 1104A and 1104B, are housed in the holes 1140A and 1140B, or 1140'A and 1140'B, and an unlocked position, which the fingers 1104A and 1104B are at the outside of the holes 1104A and 1104B, or 1104'A and 1104'B. When the locking means 1010 are locked, the translation of the closing means 1004 is blocked, so that the closing means 4 can not be opened or closed by the operator, and the translation of the protection device 1009 is blocked, so that the protective device 9 can not be moved by the operator between the retracted position and the protective position, or vice versa.

La position des moyens de verrouillage 1010 est commandée par des moyens de commande 13 comprenant une poignée fixée à la barre transversale 1041 et reliée aux deux doigts 1104A et 1104B par des câbles 13A et 13B. Les moyens de commande 13 sont mobiles entre une position de repos, dans laquelle aucune action n'est exercée sur la poignée et dans laquelle les doigts 1104A et 1104B sont logés dans les trous 1104A et 1104B, ou 1104'A et 1104'B, et une position activée, dans laquelle l'opérateur actionne la poignée de manière à extraire les doigts 1104A et 1104B hors des trous 1104A et 1104B, ou 1104'A et 1104'B.The position of the locking means 1010 is controlled by control means 13 comprising a handle attached to the cross bar 1041 and connected to the two fingers 1104A and 1104B by cables 13A and 13B. The control means 13 are movable between a rest position, in which no action is exerted on the handle and in which the fingers 1104A and 1104B are housed in the holes 1104A and 1104B, or 1104'A and 1104'B, and an activated position, in which the operator operates the handle to pull the fingers 1104A and 1104B out of the holes 1104A and 1104B, or 1104'A and 1104'B.

Les moyens de verrouillage 1010 sont verrouillés par défaut. Lorsqu'aucune action n'est exercée sur les moyens de commande 13, les moyens de verrouillage 1010 sont verrouillés et s'opposent au déplacement des moyens de fermeture 1004 et au déplacement du dispositif de protection 1009.The locking means 1010 are locked by default. When no action is exerted on the control means 13, the locking means 1010 are locked and oppose the movement of the closing means 1004 and the displacement of the protective device 1009.

On note L1009 une largeur du dispositif de protection 1009, mesurée perpendiculairement au plan P1. La largeur L1009 correspond à la longueur du montant horizontal 1093 et à l'espacement des montants verticaux 1091 et 1092. La largeur L9 est supérieure à 30 cm, de préférence supérieure à 60 cm.L1009 is a width of the protection device 1009, measured perpendicular to the plane P1. The width L1009 corresponds to the length of the horizontal upright 1093 and to the spacing of the uprights 1091 and 1092. The width L9 is greater than 30 cm, preferably greater than 60 cm.

Le fonctionnement du dispositif de protection 1009 est le même que celui du dispositif de protection 9 décrit en référence aux figures 1 à 3.The operation of the protection device 1009 is the same as that of the protection device 9 described with reference to the Figures 1 to 3 .

Selon une autre variante de l'invention, l'ouverture d'accès 724 et les moyens de fermeture 4 ou 1004 sont situés sur la face 72C ou 72D du garde-corps 72.According to another variant of the invention, the access opening 724 and the closing means 4 or 1004 are located on the face 72C or 72D of the guard rail 72.

Selon une autre variante de l'invention, non représentée, le poste de pilotage 8 n'est pas centré sur la face 72A du garde-corps 72. Par exemple, le poste de pilotage 8 peut être décalé latéralement par rapport au plan P1, c'est-à-dire selon une direction perpendiculaire au plan P1. En alternative, le poste de pilotage 8 est situé sur une autre face du garde-corps 72, par exemple la face 72C ou 72D. Dans une autre alternative, le poste de pilotage 8 n'est pas situé sur une face du garde corps 72 mais est installé en retrait vers le centre de la plateforme 7, par rapport au garde-corps 72.According to another variant of the invention, not shown, the cockpit 8 is not centered on the face 72A of the railing 72. For example, the cockpit 8 can be shifted laterally relative to the plane P1, that is to say in a direction perpendicular to the plane P1. Alternatively, the cockpit 8 is located on another face of the railing 72, for example the face 72C or 72D. In another alternative, the cockpit 8 is not located on a face of the guard 72 but is installed recessed towards the center of the platform 7, with respect to the guard rail 72.

Dans tous les cas, pour assurer la sécurité de l'opérateur 100, il est nécessaire que le dispositif de protection 9 soit situé derrière l'opérateur 100 lorsque ce dernier manoeuvre le poste de pilotage 8. On définit sur le plancher 71 une zone Z de positionnement de l'opérateur 100 manoeuvrant le poste de pilotage 8, dont les contours sont représentés en trait mixte aux figures 2 et 4. La zone Z contient la zone de contact entre les pieds de l'opérateur 100 et le plancher 71, lorsque l'opérateur 100 est debout et que ses mains sont positionnées sur les éléments de commande du poste de pilotage 8.In all cases, to ensure the safety of the operator 100, it is necessary that the protective device 9 is located behind the operator 100 when the latter maneuvering the cockpit 8. On the floor 71 is defined a zone Z positioning of the operator 100 operating the cockpit 8, the contours of which are shown in dashed line with the figures 2 and 4 . Zone Z contains the contact zone between the feet of the operator 100 and the floor 71, when the operator 100 is standing and his hands are positioned on the control elements of the cockpit 8.

Pour assurer la sécurité de l'opérateur, la zone Z et le dispositif de protection 9 s'étendent chacun de part et d'autre du plan P1, qui est perpendiculaire à la face 72B du garde-corps 72 sur laquelle est situé le dispositif de protection 9. Ainsi, lorsque le dispositif de protection 9 n'est pas centré sur la face 72A du garde-corps 72, le dispositif de protection 9 assure la protection de l'opérateur 100.To ensure the safety of the operator, the zone Z and the protection device 9 each extend on either side of the plane P1, which is perpendicular to the face 72B of the railing 72 on which the device is located. 9. Thus, when the protective device 9 is not centered on the face 72A of the railing 72, the protection device 9 provides protection for the operator 100.

D'autres modes de réalisation peuvent être mis en oeuvre en combinant les caractéristiques de modes de réalisations et variantes mentionnées ci-dessus.Other embodiments may be implemented by combining the features of embodiments and variants mentioned above.
