Description

La présente invention concerne un système de chargement prévu pour s'adapter sur un monte-charge, comprenant une sécurité. comme par exemple dans les documents NL9300085 , JP2004307205 et GB2435463 .The present invention relates to a loading system intended to fit on a freight elevator, including safety. as for example in the documents NL9300085 , JP2004307205 And GB2435463 .

Afin de monter des personnes à mobilité réduite, en particulier dans les escaliers, il est connu d'utiliser une installation comprenant un ou plusieurs rails de guidage fixés dans le bâtiment, recevant une nacelle motorisée disposant d'un siège prévu pour une personne qui s'assoit à une extrémité du trajet, et vient sans effort de l'autre côté.In order to climb people with reduced mobility, in particular on stairs, it is known to use an installation comprising one or more guide rails fixed in the building, receiving a motorized nacelle having a seat provided for a person who is sits at one end of the ride, and comes effortlessly to the other side.

Le siège comporte généralement à sa base une partie mâle ou femelle cylindrique disposée au centre suivant un axe vertical, qui s'ajuste sur une partie complémentaire de la nacelle, respectivement femelle ou mâle, afin d'effectuer un couplage rapide et fiable du siège qui assure la sécurité. Le siège peut aussi pivoter autour de cet axe vertical, afin de permettre une rotation de la personne pour s'asseoir ou se lever au début et en fin de parcours.The seat generally comprises at its base a cylindrical male or female part arranged in the center along a vertical axis, which adjusts to a complementary part of the nacelle, respectively female or male, in order to effect rapid and reliable coupling of the seat which ensures security. The seat can also pivot around this vertical axis, in order to allow the person to rotate to sit or get up at the start and end of the journey.

Les rails de guidage peuvent comporter deux rails parallèles superposés, fixés le long du mur ou du côté opposé, assurant un guidage en translation du siège qui reste vertical malgré la charge posée dessus.The guide rails can include two superimposed parallel rails, fixed along the wall or on the opposite side, ensuring translational guidance of the seat which remains vertical despite the load placed on it.

Suivant une variante on dispose un rail unique fixé le long du mur, comportant un profil particulier suffisamment large qui bloque la rotation de la nacelle autour de l'axe longitudinal de ce rail, afin de maintenir le siège vertical.According to a variant, there is a single rail fixed along the wall, comprising a particular sufficiently wide profile which blocks the rotation of the nacelle around the longitudinal axis of this rail, in order to maintain the seat vertical.

Suivant une autre variante on dispose un rail unique fixé en hauteur dans un même plan horizontal, recevant une nacelle qui est suspendue en dessous de ce rail par un mât comportant une hauteur variable sous l'effet d'une motorisation. On a alors simultanément un déplacement horizontal du mât sur le rail et un ajustement de la hauteur variable de la nacelle, afin de réaliser par exemple une montée en diagonale qui suit la pente d'un escalier.According to another variant, there is a single rail fixed in height in the same horizontal plane, receiving a nacelle which is suspended below this rail by a mast having a variable height under the effect of a motorization. We then simultaneously have a horizontal movement of the mast on the rail and an adjustment of the variable height of the nacelle, in order to achieve, for example, a diagonal climb which follows the slope of a staircase.

En complément, la nacelle peut recevoir un panier, qui s'ajoute au siège afin de déplacer en même temps que la personne des petites charges comme ses objets personnels.In addition, the carrycot can accommodate a basket, which is added to the seat in order to move small loads such as personal items at the same time as the person.

Le monte-personne dispose généralement d'une commande actionnée par la personne transportée, qui demande la marche ou l'arrêt du système à partir de moyens de commande disposés à proximité du siège. En cas de problème particulier, notamment en cas d'obstacle comme la présence d'une personne ou d'un objet sur le parcours, la personne transportée peut arrêter à tout moment le déplacement.The personnel lift generally has a control actuated by the person being transported, which requests the system to start or stop using control means placed near the seat. In the event of a particular problem, particularly in the event of an obstacle such as the presence of a person or an object on the route, the person being transported may stop the journey at any time.

Un type de motorisation couramment utilisé comporte un moteur électrique embarqué sur la nacelle, qui entraîne en rotation par un réducteur un pignon ajusté sur une crémaillère logée dans un rail de guidage.A type of motorization commonly used includes an electric motor on board the nacelle, which rotates a pinion fitted on a rack housed in a guide rail by a reduction gear.

Dans le cas où on souhaite utiliser ce type de monte-personne pour transporter des objets, en les posant sur le siège, ou en installant à la place de ce siège une plate-forme de réception des objets, se pose alors le problème de la commande de la nacelle qui doit assurer en permanence la sécurité pendant les déplacements.In the case where we wish to use this type of personnel lift to transport objects, by placing them on the seat, or by installing in place of this seat a platform for receiving the objects, then the problem of the control of the nacelle which must constantly ensure safety during travel.

On peut en particulier prévoir une commande à distance actionnée par un opérateur, qui commande le départ de la nacelle pour lui faire effectuer automatiquement le trajet complet.In particular, it is possible to provide a remote control activated by an operator, who commands the departure of the nacelle to make it automatically complete the entire journey.

Un problème qui se pose dans ce cas est que la nacelle peut percuter des obstacles, par exemple si l'opérateur ne voit pas le trajet complet, ne pouvant s'assurer du libre passage, ou si un obstacle imprévu arrive sur ce passage après le départ du cycle.A problem which arises in this case is that the nacelle can hit obstacles, for example if the operator does not see the complete path, being unable to ensure free passage, or if an unforeseen obstacle arrives on this passage after the start of the cycle.

La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.The present invention aims in particular to avoid these drawbacks of the prior art.

Elle propose à cet effet un système de chargement prévu pour s'adapter sur un monte-charge, tel qu'un monte-personne, comportant une nacelle mobile, caractérisé en ce qu'il comporte une plate-forme sur laquelle est destinée à être disposée une charge, des moyens de fixation configurés pour être fixés sur la nacelle, et par exemple sur une partie supérieure de la nacelle, et des moyens de détection configurés pour détecter des contraintes mécaniques appliquées latéralement sur la plate-forme.For this purpose, it proposes a loading system designed to adapt to a freight elevator, such as a personnel elevator, comprising a mobile nacelle, characterized in that it comprises a platform on which is intended to be arranged a load, fixing means configured to be fixed on the nacelle, and for example on an upper part of the nacelle, and detection means configured to detect mechanical stresses applied laterally on the platform.

La présence des moyens de détection assure la détection de tout effort anormal s'appliquant latéralement sur la plate-forme, et donc le déclanchement d'un arrêt du monte-charge lorsque la plate-forme rencontre un obstacle. Ces dispositions permettent ainsi d'optimiser la sécurité du monte-charge.The presence of the detection means ensures the detection of any abnormal force applied laterally on the platform, and therefore the triggering of a stop of the freight elevator when the platform encounters an obstacle. These arrangements thus make it possible to optimize the safety of the freight elevator.

Un autre avantage du système de chargement est que l'on peut facilement et rapidement fixer la plate-forme de manière provisoire sur la nacelle d'un monte-personne, à la place du siège, lorsque les moyens de fixation sont similaires ou identiques à ceux du siège, ce qui ne nécessite alors pas d'outillage ni de transformation, et permet un retour ultérieur de ce siège.Another advantage of the loading system is that the platform can be easily and quickly fixed temporarily on the nacelle of a personnel lift, in place of the seat, when the fixing means are similar or identical to those of the seat, which then does not require tools or transformation, and allows a subsequent return of this seat.

Le système de chargement selon l'invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The loading system according to the invention may additionally comprise one or more of the following characteristics, which can be combined with each other.

Selon un mode de réalisation de l'invention, les moyens de détection sont plus particulièrement configurés pour détecter des contraintes mécaniques relatives entre la plate-forme et les moyens de fixation. Ces dispositions permettent d'enregistrer un effort anormal s'appliquant sur la plate-forme ou sur les colis transportés par cette dernière, et donc de déclencher un arrêt du système.According to one embodiment of the invention, the detection means are more particularly configured to detect relative mechanical constraints between the platform and the fixing means. These provisions make it possible to record an abnormal force applied to the platform or to the packages transported by the latter, and therefore to trigger a shutdown of the system.

Selon un mode de réalisation de l'invention, le monte-charge est un monte-personne comportant un siège apte à être monté de manière amovible sur une base de la nacelle.According to one embodiment of the invention, the freight elevator is a personnel elevator comprising a seat capable of being removably mounted on a base of the nacelle.

Selon un mode de réalisation de l'invention, les moyens de détection comportent au moins un élément élastique configuré pour se déformer sous l'effet d'une charge disposée sur la plate-forme.According to one embodiment of the invention, the detection means comprise at least one elastic element configured to deform under the effect of a load placed on the platform.

Avantageusement, l'au moins un élément élastique comporte au moins un coussin élastiquement déformable, par exemple en élastomère. Ce matériau est simple et économique à mettre en oeuvre.Advantageously, the at least one elastic element comprises at least one elastically deformable cushion, for example made of elastomer. This material is simple and economical to use.

Selon un mode de réalisation de l'invention, les moyens de fixation comportent un support comprenant une portion de fixation configurée pour être fixée sur la nacelle, par exemple sur la base de celle-ci, et une portion de support, et la plate-forme comporte une portion de montage montée sur la portion de support.According to one embodiment of the invention, the fixing means comprise a support comprising a fixing portion configured to be fixed on the nacelle, for example on the base thereof, and a support portion, and the platform form includes a mounting portion mounted on the support portion.

Selon un mode de réalisation de l'invention, au moins un élément élastique est interposé entre la portion de support et la portion de montage.According to one embodiment of the invention, at least one elastic element is interposed between the support portion and the mounting portion.

Selon un mode de réalisation de l'invention, la portion de support comporte deux barres parallèles disposées perpendiculairement au sens de déplacement du monte-charge, et la portion de montage comporte deux rails de montage délimitant chacun une cavité dans laquelle est insérée une barre respective, un élément élastique étant interposé entre chaque barre et le rail de montage respectif. On réalise de cette manière un ensemble qui permet de détecter les contraintes dans les différentes directions liées au sens de marche.According to one embodiment of the invention, the support portion comprises two parallel bars arranged perpendicular to the direction of movement of the freight elevator, and the mounting portion comprises two mounting rails each delimiting a cavity in which a respective bar is inserted , an elastic element being interposed between each bar and the respective mounting rail. In this way, a set is created which makes it possible to detect the constraints in the different directions linked to the direction of travel.

Selon un mode de réalisation de l'invention, la portion de support comporte un plateau horizontal.According to one embodiment of the invention, the support portion comprises a horizontal plate.

Selon un mode de réalisation de l'invention, les barres s'étendent au niveau des bords latéraux du plateau horizontal, et les moyens de détection comporte en outre un élément élastique interposé entre la plate-forme et le plateau horizontal, et plus particulièrement entre la face supérieure du plateau horizontal et la face inférieure de la plate-forme.According to one embodiment of the invention, the bars extend at the level of the lateral edges of the horizontal plate, and the detection means further comprises an elastic element interposed between the platform and the horizontal plate, and more particularly between the upper face of the horizontal plate and the lower face of the platform.

Selon un mode de réalisation de l'invention, les moyens de détection comportent des capteurs configurés pour détecter un déplacement relatif entre la plate-forme et les moyens de fixation. On a ainsi de manière simple une détection des contraintes par la mesure de la déformation des éléments élastiques.According to one embodiment of the invention, the detection means comprise sensors configured to detect a relative movement between the platform and the fixing means. We thus have a simple detection of stresses by measuring the deformation of the elastic elements.

Dans ce cas, les moyens de détection comportent avantageusement au moins un capteur configuré pour détecter un déplacement vertical de la plate-forme par rapport aux moyens de fixation, et au moins un capteur configuré pour détecter un déplacement de la plate-forme par rapport aux moyens de fixation transversalement au sens de marche de la plate-forme. On obtient la détection des différentes contraintes qui peuvent venir des forces appliquées dans le sens de la marche.In this case, the detection means advantageously comprise at least one sensor configured to detect a vertical movement of the platform relative to the fixing means, and at least one sensor configured to detect a movement of the platform relative to the fixing means transversely to the direction of travel of the platform. We obtain the detection of the different constraints which can come from the forces applied in the direction of travel.

Avantageusement, les capteurs comportent des contacts électriques disposés en série avec des moyens d'alimentation d'une motorisation électrique de la nacelle. On a ainsi un moyen simple d'arrêt du moteur électrique de la nacelle.Advantageously, the sensors comprise electrical contacts arranged in series with means of powering an electric motor of the nacelle. We thus have a simple way to stop the electric motor of the nacelle.

Avantageusement, la plate-forme comporte des rebords latéraux. Les efforts latéraux sur un colis sont dans ce cas transmis à la plate-forme par ces rebords.Advantageously, the platform has side edges. The lateral forces on a package are in this case transmitted to the platform by these edges.

Cette fixation simple à assembler, permet de plus un pivotement de la plate-forme autour de cet axe.According to one embodiment of the invention, the fixing means comprise a nesting along a vertical axis centered on this platform. This simple-to-assemble fixing also allows the platform to pivot around this axis.

En complément, le système de chargement peut comporter un capteur de contrôle configuré pour contrôler la mise en place complète des moyens de fixation sur la base. Ce capteur de contrôle sécurise ainsi le montage de la plate-forme.In addition, the loading system may include a control sensor configured to monitor the complete installation of the means of fixing to the base. This control sensor thus secures the assembly of the platform.

Selon un mode de réalisation de l'invention, le support est configuré pour coopérer de manière amovible avec des moyens d'accouplement prévus sur le siège du monte-personne, et est donc également configuré pour fixer le siège sur la base de la nacelle. Ces dispositions permettent d'utiliser le même élément pour réaliser la fixation du siège et de la plate-forme sur la nacelle, et donc de limiter les coûts du système de chargement.According to one embodiment of the invention, the support is configured to cooperate removably with coupling means provided on the seat of the manlift, and is therefore also configured to fix the seat on the base of the nacelle. These arrangements make it possible to use the same element to attach the seat and the platform to the nacelle, and therefore to limit the costs of the loading system.

Selon un mode de réalisation de l'invention, les capteurs sont montés sur le support. Ces dispositions permettent donc d'utiliser les capteurs aussi bien en configuration monte-charge qu'en configuration monte-personne.According to one embodiment of the invention, the sensors are mounted on the support. These arrangements therefore make it possible to use the sensors both in a freight elevator configuration and in a personnel elevator configuration.

Selon un mode de réalisation de l'invention, différents types de revêtements de surface peuvent être utilisés pour recouvrir la plate-forme afin de pouvoir adapter cette dernière en fonction de son utilisation.According to one embodiment of the invention, different types of surface coverings can be used to cover the platform in order to be able to adapt the latter according to its use.

Selon un mode de réalisation de l'invention, le système de chargement comporte des moyens de verrouillage configurés pour verrouiller la plate-forme dans sa position d'utilisation. Les moyens de verrouillage sont avantageusement déplaçables entre position de verrouillage dans laquelle les moyens de verrouillage verrouillent la plate-forme dans sa position d'utilisation, et une position de libération dans laquelle les moyens de verrouillage libèrent la plate-forme et autorisent un déplacement de la plate-forme vers sa position de dégagement.According to one embodiment of the invention, the loading system comprises locking means configured to lock the platform in its position of use. The locking means are advantageously movable between locking position in which the locking means lock the platform in its position of use, and a release position in which the locking means release the platform and allow movement of the platform towards its release position.

Par exemple, les moyens de verrouillage peuvent comporter un organe de verrouillage, tel qu'un taquet de verrouillage, monté mobile sur la plate-forme entre position de verrouillage dans laquelle l'organe de verrouillage coopère avec le support de manière à verrouiller la plate-forme dans sa position d'utilisation, et une position de libération dans laquelle l'organe de verrouillage autorise un déplacement de la plate-forme vers sa position de dégagement.For example, the locking means may comprise a locking member, such as a locking tab, movably mounted on the platform between locking position in which the locking member cooperates with the support so as to lock the platform -form in its position of use, and a release position in which the locking member allows movement of the platform towards its release position.

La figure 1 présente un monte-personne comportant deux rails de guidage parallèles 2 fixés au mur en suivant la pente d'un escalier 4, et une nacelle motorisée 6 pouvant coulisser le long de ces rails de guidage 2. La nacelle 6 dispose d'un plateau horizontal 8 équipé en son centre d'un arbre vertical 10 formant une base, qui présente dans sa partie supérieure un téton de centrage cylindrique. Le monte-personne comporte en outre un siège 12 qui comporte, dans sa partie inférieure, un tube vertical 14 venant s'emboîter sur le téton de centrage de l'arbre 10 de la nacelle 6. Ce tube vertical 14 permet une rotation du siège 12 autour d'un axe vertical. Il permet aussi de manière simple et rapide une dépose et une repose du siège 12 sur la nacelle 6.There figure 1 presents a personnel lift comprising two parallel guide rails 2 fixed to the wall following the slope of a staircase 4, and a motorized nacelle 6 which can slide along these guide rails 2. The nacelle 6 has a horizontal platform 8 equipped in its center with a vertical shaft 10 forming a base, which has in its upper part a cylindrical centering pin. The personnel lift further comprises a seat 12 which comprises, in its lower part, a vertical tube 14 which fits onto the centering pin of the shaft 10 of the nacelle 6. This vertical tube 14 allows a rotation of the seat 12 around a vertical axis. It also allows the seat 12 to be removed and reinstalled on the nacelle 6 in a simple and rapid manner.

La figure 2 présente une nacelle identique 6 comportant l'arbre vertical 10, recevant un système modulaire de chargement 20 selon l'invention présentant, comme pour le siège 12, un élément de fixation comprenant un tube vertical 14 qui s'emboîte sur le téton de centrage de l'arbre 10.There figure 2 presents an identical nacelle 6 comprising the vertical shaft 10, receiving a modular loading system 20 according to the invention presenting, as for the seat 12, a fixing element comprising a vertical tube 14 which fits onto the centering pin of tree 10.

On peut ainsi facilement, sans outillage particulier ni modification de la nacelle 6, déposer le siège 12 pour y installer à la place le système de chargement 20, ou faire l'opération inverse.We can thus easily, without special tools or modification of the nacelle 6, remove the seat 12 to install the loading system 20 there instead, or do the opposite operation.

La figure 3 présente le support 30 du système modulaire de chargement 20. Le support 30 comporte un plateau horizontal 32 présentant une face inférieure à partir de laquelle s'étend le tube vertical 14, et des barres parallèles 34 de section rectangulaire s'étendant au niveau des bords latéraux du plateau horizontal 32. Avantageusement, les barres parallèles 34 sont disposées de manière symétrique par rapport à l'axe du tube vertical 14, et s'étendent perpendiculairement aux rails de guidage 2 du monte-personne.There Figure 3 presents the support 30 of the modular loading system 20. The support 30 comprises a horizontal plate 32 having a lower face from which the vertical tube 14 extends, and parallel bars 34 of rectangular section extending at the edges side of the horizontal plate 32. Advantageously, the parallel bars 34 are arranged symmetrically with respect to the axis of the vertical tube 14, and extend perpendicular to the guide rails 2 of the personnel lift.

La figure 4 présente le système modulaire de chargement 20 comportant une plate-forme 40 équipée de deux rebords latéraux continus 42 s'étendant à partir de la face supérieure de la plate-forme. La surface supérieure de la plate-forme 40 peut par exemple présenter une rugosité de surface obtenue par un relief réalisé notamment sous la forme d'un quadrillage, ou être réalisée dans un matériau à grand coefficient de frottement, tel que du caoutchouc.There figure 4 presents the modular loading system 20 comprising a platform 40 equipped with two continuous side edges 42 extending from the upper face of the platform. The upper surface of the platform 40 may for example have a surface roughness obtained by a relief produced in particular in the form of a grid, or be made of a material with a high coefficient of friction, such as rubber.

La plate-forme 40 comporte en outre, sur sa face inférieure, deux rails de montage 44 écartés et s'étendant de manière symétrique par rapport à un plan médian de la plate-forme. Chaque rail de montage 44 forme une cavité de section rectangulaire posée à plat, comportant une ouverture latérale disposée au milieu du petit côté tourné vers le centre de la plate-forme 40.The platform 40 further comprises, on its lower face, two mounting rails 44 spaced apart and extending symmetrically with respect to a median plane of the platform. Each mounting rail 44 forms a cavity of rectangular section laid flat, comprising a lateral opening arranged in the middle of the short side facing the center of the platform 40.

Chaque rail de montage 44 reçoit une barre 34 du support 30 qui est ajustée au centre de la cavité respective, le plateau horizontal 32 étant centré dans l'ouverture latérale de ce rail de montage.Each mounting rail 44 receives a bar 34 of the support 30 which is adjusted to the center of the respective cavity, the horizontal plate 32 being centered in the lateral opening of this mounting rail.

L'espace intermédiaire de largeur sensiblement constante entre une barre 34 et le rail de montage 44 respectif est occupé par un coussin élastiquement déformable 46 réalisé en un matériau souple et déformable, tel qu'en élastomère et notamment en élastomère polyuréthane, formant un ressort qui permet des mouvements relatifs de faible amplitude entre la plate-forme 40 et le support 30 avec un rappel élastique dans la position d'origine.The intermediate space of substantially constant width between a bar 34 and the respective mounting rail 44 is occupied by an elastically deformable cushion 46 made of a flexible and deformable material, such as elastomer and in particular polyurethane elastomer, forming a spring which allows relative movements of small amplitude between the platform 40 and the support 30 with an elastic return to the original position.

En variante, on peut disposer des ressorts métalliques pour relier la plate-forme 40 au support 30, comme des lames flexibles ou des ressorts hélicoïdaux.Alternatively, metal springs can be used to connect the platform 40 to the support 30, such as flexible blades or helical springs.

On permet ainsi suivant les contraintes appliquées sur la plate-forme 40, des petits mouvements relatifs de cette plate-forme de translation ou de rotation suivant les différents axes, par rapport au support comprenant le tube vertical 14.This allows, depending on the constraints applied to the platform 40, small relative movements of this platform of translation or rotation along the different axes, relative to the support comprising the vertical tube 14.

Selon le mode de réalisation représenté sur la figure 4, chaque rail de montage 44 est équipé de capteurs de proximité fixés sur ce rail de montage, dont la partie active vient à proximité de la barre 34 respective pour mesurer la distance. Chaque rail de montage 44 comprend par exemple un capteur inférieur 48 disposé verticalement en dessous de la barre 34 respective, et un capteur latéral 50 disposé sur le côté de cette barre.According to the embodiment shown on the Figure 4 , each mounting rail 44 is equipped with proximity sensors fixed on this mounting rail, the active part of which comes close to the respective bar 34 to measure the distance. Each mounting rail 44 comprises for example a lower sensor 48 arranged vertically below the respective bar 34, and a lateral sensor 50 arranged on the side of this bar.

En particulier, on peut utiliser des capteurs mécaniques avec un contact, ou inductifs sans contact, qui peuvent détecter un seuil de distance, ou mesurer de manière progressive la variation de distance.In particular, mechanical sensors with a contact, or inductive without contact, can be used, which can detect a distance threshold, or progressively measure the distance variation.

Les capteurs 48, 50 sont reliés par des fils à un boîtier électrique de commande 52 fixé sur le tube 14, afin de transmettre des informations à la commande du moteur de la nacelle 6.The sensors 48, 50 are connected by wires to an electrical control box 52 fixed on the tube 14, in order to transmit information to the control of the motor of the nacelle 6.

Les capteurs 48, 50 sont configurés pour détecter des mouvements relatifs de translation ou de rotation de la plate-forme 40 par rapport au support 30, provenant de contraintes extérieures appliquées sur cette plate-forme qui sont suffisamment importantes pour déformer le coussin élastiquement déformable 46 assurant la liaison entre la plate-forme 40 et le support 30. On réalise ainsi de manière simple un capteur de contraintes.The sensors 48, 50 are configured to detect relative translational or rotational movements of the platform 40 relative to the support 30, coming from external stresses applied to this platform which are significant enough to deform the elastically deformable cushion 46 ensuring the connection between the platform 40 and the support 30. A stress sensor is thus produced in a simple manner.

La figure 5 présente en variante deux capteurs inférieurs 48 fixés sur le plateau horizontal 32 du support 30, et deux capteurs latéraux 50 fixés sur les barres 34 respectives. Selon cette variante, la partie active de chaque capteur inférieur 48 vient à proximité de la plate-forme 40, et la partie active de chaque capteur latéral vient à proximité de la face latérale du rail de montage 44 respectif.There figure 5 alternatively presents two lower sensors 48 fixed on the horizontal plate 32 of the support 30, and two side sensors 50 fixed on the respective bars 34. According to this variant, the active part of each lower sensor 48 comes close to the platform 40, and the active part of each side sensor comes close to the side face of the respective mounting rail 44.

De la même manière, ces capteurs 48, 50 sont configurés pour détecter les mouvements de translation ou de rotation de la plate-forme 40 par rapport au support 30, dépendant des contraintes extérieures appliquées sur cette plate-forme.In the same way, these sensors 48, 50 are configured to detect the translation or rotation movements of the platform 40 by relative to the support 30, depending on the external constraints applied to this platform.

Selon la variante de réalisation représentée sur la figure 5, un élément élastiquement déformable 47 peut également être intercalé entre la face inférieure de la plate-forme 40 et la face supérieure du plateau 32.According to the alternative embodiment shown on the figure 5 , an elastically deformable element 47 can also be inserted between the lower face of the platform 40 and the upper face of the plate 32.

La figure 6 présente la nacelle 6 couverte par un capot de protection 70 qui recouvre l'arbre vertical, comprenant sur le dessus une ouverture laissant passer le tube 14 du système de chargement 20 recevant un colis 72 de grande hauteur.There Figure 6 presents the nacelle 6 covered by a protective cover 70 which covers the vertical shaft, comprising on the top an opening allowing the tube 14 of the loading system 20 receiving a package 72 of great height to pass.

La nacelle 6 en train de monter en suivant l'escalier 4, arrive dans la position A où le sommet du colis 72 vient en appui sous le plafond 74 se trouvant au-dessus de cet escalier. Une charge verticale F s'applique alors sur le colis 72, ce qui entraîne une déformation des coussins élastiquement déformables 46 et donc un déplacement de la plate-forme 40 par rapport au support 30. Un tel déplacement de la plate-forme 40 est mesuré par les capteurs inférieurs 48 et le mouvement de la nacelle est aussitôt arrêté.The nacelle 6, in the process of ascending following the staircase 4, arrives in position A where the top of the package 72 comes to rest under the ceiling 74 located above this staircase. A vertical load F then applies to the package 72, which causes a deformation of the elastically deformable cushions 46 and therefore a movement of the platform 40 relative to the support 30. Such a movement of the platform 40 is measured by the lower sensors 48 and the movement of the nacelle is immediately stopped.

La figure 7 présente la nacelle 6 en train de descendre en suivant l'escalier 4, le haut du colis 72 venant buter sur l'angle du plafond 74. On a alors un effort transversal F sur le colis 72 qui est transmis à un rebord latéral 42 de la plate-forme 40, ce qui déplace cette plate-forme par rapport au support 30 en comprimant les coussins élastiquement déformables 46.There Figure 7 presents the nacelle 6 in the process of descending following the staircase 4, the top of the package 72 coming up against the angle of the ceiling 74. We then have a transverse force F on the package 72 which is transmitted to a lateral edge 42 of the platform 40, which moves this platform relative to the support 30 by compressing the elastically deformable cushions 46.

De la même manière au moins un capteur latéral 50 détecte cette contrainte, et arrête aussitôt le mouvement de la nacelle 6.In the same way at least one lateral sensor 50 detects this constraint, and immediately stops the movement of the nacelle 6.

On notera que la présence de chaque côté de la plate-forme 40 d'un capteur inférieur 48 et d'un capteur latéral 50, permet de surveiller dans un plan transversal, à la fois les déplacements verticaux et latéraux de la plate-forme 40 par rapport au support 30, et les rotations de cette plate-forme autour de l'axe longitudinal.It will be noted that the presence on each side of the platform 40 of a lower sensor 48 and a lateral sensor 50, makes it possible to monitor in a transverse plane, both the vertical and lateral movements of the platform 40 relative to the support 30, and the rotations of this platform around the longitudinal axis.

Pour la commande du moteur électrique de la nacelle 6, on peut disposer en particulier les différents capteurs de sécurisation 48, 50 en série sur l'alimentation de ce moteur, en prévoyant une position fermée de tous les capteurs en l'absence de contrainte sur la plate-forme 40, et une position ouverte de chaque capteur quand il enregistre un déplacement de la plate-forme 40 par rapport au support 30. On réalise ainsi de manière simple la sécurisation, en arrêtant de suite la motorisation.For the control of the electric motor of the nacelle 6, it is possible in particular to arrange the various safety sensors 48, 50 in series on the power supply of this motor, providing a closed position for all the sensors in the absence of constraint on the platform 40, and an open position of each sensor when it records a movement of the platform 40 relative to the support 30. Securing is thus achieved in a simple manner, by immediately stopping the motorization.

On notera que les capteurs inférieurs 48 peuvent aussi détecter une charge trop importante posée sur la plate-forme 40, qui écraserait les coussins élastiquement déformables 46 de manière trop prononcée, ce qui entraînerait de la même manière un arrêt de l'installation permettant de la protéger.It will be noted that the lower sensors 48 can also detect an excessively heavy load placed on the platform 40, which would crush the elastically deformable cushions 46 too pronouncedly, which would in the same way cause the installation to stop allowing the protect.

Par ailleurs on utilise avantageusement pour la motorisation de la nacelle 6, un entraînement par un moteur électrique comportant une cinématique irréversible qui permet quelle que soit la charge de cette nacelle, de bloquer sa position à tout moment quand le moteur n'est plus alimenté en courant.Furthermore, for the motorization of the nacelle 6, we advantageously use a drive by an electric motor comprising irreversible kinematics which allows, whatever the load of this nacelle, to block its position at any time when the motor is no longer supplied with power. fluent.

En complément, l'assemblage du système de chargement 20 sur la nacelle 6 peut être sécurisé par un capteur supplémentaire disposé sur le support 30, comprenant par exemple un capteur de proximité qui vérifie le bon positionnement du tube 14 sur l'arbre 10.In addition, the assembly of the loading system 20 on the nacelle 6 can be secured by an additional sensor placed on the support 30, comprising for example a proximity sensor which verifies the correct positioning of the tube 14 on the shaft 10.

On peut en particulier prévoir un contact électrique qui reste ouvert tant que l'assemblage n'est pas correct. Dans ce cas, la nacelle 6 ne démarre pas pour éviter un accident.In particular, it is possible to provide an electrical contact which remains open as long as the assembly is not correct. In this case, the nacelle 6 does not start to avoid an accident.

Le système modulaire de chargement suivant l'invention permet deux usages sécurisés différents du monte-personne, qui sont facilement et rapidement interchangeables sans outillage particulier, et sans modification du système d'origine.The modular loading system according to the invention allows two different secure uses of the personnel lift, which are easily and quickly interchangeable without special tools, and without modification of the original system.

Selon un mode de réalisation de l'invention, le support 30 peut être configuré pour coopérer de manière amovible avec des moyens d'accouplement prévus sur le siège 12 du monte-personne. Dans un tel cas, le support 30 est donc également configuré pour fixer le siège 12 sur la base 10 de la nacelle 6. Ces dispositions permettent d'utiliser le même élément pour réaliser la fixation du siège 12 et de la plate-forme 40 sur la nacelle 6. Ces dispositions permettent également, lorsque les capteurs 48, 50 sont fixés sur le support 30, d'utiliser les capteurs aussi bien en configuration monte-charge qu'en configuration monte-personne.According to one embodiment of the invention, the support 30 can be configured to cooperate removably with coupling means provided on the seat 12 of the personnel lift. In such a case, the support 30 is therefore also configured to fix the seat 12 on the base 10 of the nacelle 6. These arrangements make it possible to use the same element to fix the seat 12 and the platform 40 on the nacelle 6. These arrangements also allow, when the sensors 48, 50 are fixed on the support 30, to use the sensors both in freight elevator configuration and in personnel elevator configuration.

Les figures 8 à 11 représentent un mode de réalisation du système modulaire de chargement 20 qui diffère de celui représenté sur les figures 1 à 7 essentiellement en ce que la plate-forme 40 est montée pivotante sur le support 30 entre une position d'utilisation (représentée sur les figures 9 et 10) dans laquelle la plate-forme est apte à s'étendre sensiblement horizontalement et une position de dégagement (représentée sur la figure 8) dans laquelle la plate-forme 40 est apte à s'étendre sensiblement verticalement, et en ce que les moyens de détection comportent au moins un organe de détection 55 monté sur un premier bord latéral transversal 56 de la plate-forme 40, et au moins un organe de détection 57 monté sur un deuxième bord latéral transversal 58 de la plate-forme 40 opposé au premier bord latéral transversal 56.THE figures 8 to 11 represent an embodiment of the modular loading system 20 which differs from that represented on the figures 1 to 7 essentially in that the platform 40 is pivotally mounted on the support 30 between a position of use (shown on the figures 9 and 10 ) in which the platform is capable of extending substantially horizontally and a clearance position (shown on the figure 8 ) in which the platform 40 is able to extend substantially vertically, and in that the detection means comprise at least one detection member 55 mounted on a first transverse lateral edge 56 of the platform 40, and at least one detection member detection 57 mounted on a second transverse side edge 58 of the platform 40 opposite the first transverse side edge 56.

Comme montré plus particulièrement sur la figure 8, le support 30 comporte une portion de support 59 s'étendant sensiblement horizontalement, et une portion de fixation 61 s'étendant sensiblement verticalement et configurée pour être fixée sur la nacelle 6.As shown more particularly on the figure 8 , the support 30 comprises a support portion 59 extending substantially horizontally, and a fixing portion 61 extending substantially vertically and configured to be fixed on the nacelle 6.

Comme montré plus particulièrement sur la figure 10, la plate-forme 40 comporte une portion de montage 62 montée pivotante sur la portion de support 59 du support 30, la plate-forme 40 est configurée pour s'étendre, en position d'utilisation, au-dessus de la nacelle 6 du monte-charge, et le système modulaire de chargement 20 est configuré de telle sorte que, lorsque la plate-forme 40 est en position d'utilisation, la portion de fixation 61 est sensiblement centrée par rapport à la plate-forme 40.As shown more particularly on the Figure 10 , the platform 40 comprises a mounting portion 62 pivotally mounted on the support portion 59 of the support 30, the platform 40 is configured to extend, in the position of use, above the nacelle 6 of the freight elevator, and the modular loading system 20 is configured such that, when the platform 40 is in the position of use, the fixing portion 61 is substantially centered with respect to the platform 40.

Avantageusement, le système modulaire de chargement 20 comporte des premiers moyens de détection de positionnement configurés pour détecter un positionnement de la plate-forme 40 dans sa position d'utilisation, et des deuxièmes moyens de détection de positionnement configurés pour détecter un positionnement de la plate-forme 40 dans sa position de dégagement. Selon le mode de réalisation représenté sur les figures, les premiers moyens de détection de positionnement comportent un premier commutateur 63 disposé sur le support 30 et configuré pour coopérer avec la plate-forme 40, et les deuxièmes moyens de détection de positionnement comportent un deuxième commutateur 64 disposé également sur le support 30 et configuré pour coopérer avec la portion de montage 62 de la plate-forme 40.Advantageously, the modular loading system 20 comprises first positioning detection means configured to detect a positioning of the platform 40 in its position of use, and second positioning detection means configured to detect a positioning of the platform -form 40 in its release position. According to the embodiment shown in the figures, the first positioning detection means comprise a first switch 63 arranged on the support 30 and configured to cooperate with the platform 40, and the second positioning detection means comprise a second switch 64 also placed on the support 30 and configured to cooperate with the mounting portion 62 of the platform 40.

Selon un mode de réalisation de l'invention, le système modulaire de chargement 20 comporte des moyens de contrôle configurés pour, en conditions d'utilisation, empêcher le fonctionnement du monte-charge lorsque la plate-forme 40 n'est ni dans sa position d'utilisation, ni dans sa position de dégagement. Ainsi, lorsqu'aucun des premier et deuxième commutateurs 63, 64 ne détecte la présence de la plate-forme 40 dans l'une de ses positions d'utilisation ou de dégagement, le monte-charge ne peut être déplacé.According to one embodiment of the invention, the modular loading system 20 comprises control means configured to, in conditions of use, prevent the operation of the freight elevator when the platform 40 is neither in its position of use, nor in its release position. Thus, when none of the first and second switches 63, 64 detects the presence of the platform 40 in one of its use or release positions, the freight elevator cannot be moved.

Selon le mode de réalisation représenté sur les figures 8 à 10, le système modulaire de chargement 20 comporte un organe de verrouillage 65 monté mobile sur la plate-forme 40 entre position de verrouillage dans laquelle l'organe de verrouillage 65 coopère avec le support 30 de manière à verrouiller la plate-forme 40 dans sa position d'utilisation, et une position de libération dans laquelle l'organe de verrouillage 65 autorise un déplacement de la plate-forme 40 vers sa position de dégagement. Le système modulaire de chargement 20 comporte avantageusement des moyens de rappel configurés pour rappeler l'organe de verrouillage 65 vers sa position de verrouillage.According to the embodiment shown on the figures 8 to 10 , the modular loading system 20 comprises a locking member 65 movably mounted on the platform 40 between locking position in which the locking member 65 cooperates with the support 30 so as to lock the platform 40 in its position of use, and a release position in which the locking member 65 allows movement of the platform 40 towards its release position. The modular loading system 20 advantageously comprises return means configured to return the locking member 65 to its locking position.

Selon un mode de réalisation de l'invention, le système modulaire de chargement 20 comporte des moyens d'immobilisation configurés pour immobiliser la plate-forme 40 dans sa position de dégagement. Les moyens d'immobilisation comportent par exemple un premier aimant (non représenté sur les figures) disposé sur la portion de montage 62 de la plate-forme 40, et un deuxième aimant (non représenté sur les figures) disposé sur la portion de support 59 du support 30. Les premier et deuxième aimants sont avantageusement configurés pour coopérer l'un avec l'autre lorsque la plate-forme 40 est en position de dégagement de manière à immobiliser celle-ci dans cette position.According to one embodiment of the invention, the modular loading system 20 comprises immobilization means configured to immobilize the platform 40 in its release position. The immobilization means comprise for example a first magnet (not shown in the figures) placed on the mounting portion 62 of the platform 40, and a second magnet (not shown in the figures) placed on the support portion 59 of the support 30. The first and second magnets are advantageously configured to cooperate with one another when the platform 40 is in the release position so as to immobilize it in this position.

Selon le mode de réalisation représenté sur les figures, la plate-forme 40 est pourvue de quatre rebords latéraux 42 continus.According to the embodiment shown in the figures, the platform 40 is provided with four continuous side edges 42.

Selon un mode de réalisation de l'invention, la plate-forme 40 peut comporter au moins un orifice d'évacuation d'eau, et par exemple une pluralité d'orifices d'évacuation d'eau. Ces dispositions permettent d'assurer une évacuation de l'eau présente sur la plate-forme en cas d'installation du système modulaire de chargement 20 à l'extérieur d'un bâtiment.According to one embodiment of the invention, the platform 40 may comprise at least one water evacuation orifice, and for example a plurality of water evacuation orifices. These arrangements make it possible to ensure evacuation of water present on the platform in the event of installation of the modular loading system 20 outside a building.

Selon le mode de réalisation représenté sur les figures, chaque organe de détection 55, 57 est monté mobile sur le bord latéral transversal respectif de la plate-forme 40 entre une position déployée dans laquelle l'organe de détection 55, 57 est apte à entrer en contact avec un obstacle disposé sur le trajet de déplacement de la plate-forme 40, et une position rentrée dans laquelle les moyens de détection sont aptes à détecter la présence d'un obstacle sur le trajet de déplacement de la plate-forme. Il doit être noté qu'en position rentrée, chaque organe de détection 55, 57 peut bien entendu encore faire saillie du bord latéral transversal respectif de la plate-forme.According to the embodiment shown in the figures, each detection member 55, 57 is movably mounted on the respective transverse lateral edge of the platform 40 between a deployed position in which the detection member 55, 57 is capable of entering in contact with an obstacle placed on the path of movement of the platform 40, and a retracted position in which the detection means are capable of detecting the presence of an obstacle on the path of movement of the platform. It should be noted that in the retracted position, each detection member 55, 57 can of course still project from the respective transverse side edge of the platform.

Comme montré plus particulièrement sur les figures 10 et 11, les moyens de détection comportent :

  • au moins un élément élastique 66, 67 interposé entre chaque organe de détection 55, 57 et la plate-forme 40, chaque élément élastique 66, 67 étant configuré pour se déformer sous l'effet de contraintes mécaniques appliquées sur l'organe de détection 55, 57 respectif,
  • au moins un premier point de contact électrique 68 et un deuxième point de contact électrique 69 prévus sur la plate-forme 40, et
  • au moins un premier et un deuxième organes de contact électriquement conducteurs 71, 72, chacun des premier et deuxième organes de contact 71, 72 étant monté mobile par rapport à la plate-forme 40 entre une position de repos dans laquelle l'organe de contact 71, 72est isolé électriquement du point de contact électrique 68, 69 respectif, et une position de contact dans laquelle l'organe de contact 71, 72 est relié électriquement au point de contact électrique 68, 69 respectif.
As shown more particularly on the figures 10 and 11 , the detection means include:
  • at least one elastic element 66, 67 interposed between each detection member 55, 57 and the platform 40, each elastic element 66, 67 being configured to deform under the effect of mechanical stresses applied to the detection member 55 , 57 respective,
  • at least a first electrical contact point 68 and a second electrical contact point 69 provided on the platform 40, and
  • at least a first and a second electrically conductive contact members 71, 72, each of the first and second contact members 71, 72 being mounted movable relative to the platform 40 between a rest position in which the contact member 71, 72 is electrically isolated from the respective electrical contact point 68, 69, and a contact position in which the contact member 71, 72 is electrically connected to the respective electrical contact point 68, 69.

Selon un tel mode de réalisation de l'invention, chaque organe de détection 55, 57 est configuré pour déplacer l'organe de contact 71, 72 respectif vers sa position de contact lorsque ledit organe de détection 55, 57 est déplacé vers sa position rentrée.According to such an embodiment of the invention, each detection member 55, 57 is configured to move the respective contact member 71, 72 towards its contact position when said detection member 55, 57 is moved to its retracted position. .

Une telle configuration des moyens de détection permet de détecter aisément tout obstacle disposé sur le trajet de déplacement de la plate-forme, et ainsi de commander l'arrêt du monte-charge lorsqu'un tel obstacle est détecté.Such a configuration of the detection means makes it possible to easily detect any obstacle placed on the path of movement of the platform, and thus to control the stopping of the freight elevator when such an obstacle is detected.

Comme il va de soi, l'invention ne se limite pas aux formes d'exécution de ce système modulaire de chargement, décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation.As it goes without saying, the invention is not limited to the forms of execution of this modular loading system, described above by way of example, on the contrary it embraces all the variant embodiments.
