Description

DISPOSITIF DE MANUTENTION  HANDLING DEVICE
La présente invention concerne un dispositif de manutention. L'invention concerne également un système de franchissement d'obstacles au sol comprenant au moins deux dispositifs de manutention. Le domaine de l'invention est celui de la manutention de charges, notamment à bord des navires. The present invention relates to a handling device. The invention also relates to a ground obstacle clearance system comprising at least two handling devices. The field of the invention is that of the handling of loads, especially on board ships.
A bord des navires en service, en carénage ou en construction, le franchissement des obstacles au sol par un matériel pesant et encombrant est une opération délicate. En particulier, les surbaux de portes étanches constituent un obstacle au roulement des chariots et transpalettes.  On ships in service, in fairing or under construction, the crossing of obstacles on the ground by heavy and bulky equipment is a delicate operation. In particular, coamings of watertight doors are an obstacle to the rolling of trucks and pallet trucks.
De manière classique, le franchissement des surbaux est réalisé par hissage de la charge à l'aide de palans de manutention. Les palans sont accrochés à des pitons de manutention de part et d'autre du surbau. L'opération de franchissement est lente, nécessite plusieurs opérateurs et comporte des risques d'accident. La fixation de chaque piton doit être étudiée et calibrée en bureau d'études. L'installation nécessite des soins particuliers et des contrôles sévères et réguliers.  In a conventional manner, the crossing of the coamings is achieved by hoisting the load using handling hoists. The hoists are hooked to the handlebars on both sides of the coaming. The crossing operation is slow, requires several operators and involves risks of accident. The fixing of each peak must be studied and calibrated in design office. The installation requires special care and strict and regular controls.
EP-A-2 210 793 décrit un système de franchissement d'obstacles au sol, comprenant deux chariots de transport articulés l'un avec l'autre. Un espace intermédiaire, qui est plus élevé et plus large que les obstacles à franchir, est formé sous l'articulation reliant les chariots. En pratique, le chariot arrière reçoit la charge tandis que le chariot avant est levé par-dessus l'obstacle en vue de son franchissement. La charge est alors transférée du chariot arrière vers le chariot avant par dessus de l'obstacle. Enfin, le chariot arrière est levé à son tour par dessus l'obstacle, rejoignant ainsi le chariot avant et la charge. Ce système n'est pas entièrement satisfaisant, notamment lorsque la charge est très lourde et/ou très encombrante. L'opération est fatigante et comporte des risques de blessures, notamment liés à la présence de l'articulation et au levage des chariots.  EP-A-2 210 793 discloses an obstacle clearance system on the ground, comprising two transport carriages articulated with each other. An intermediate space, which is higher and wider than the obstacles to be crossed, is formed under the articulation connecting the carriages. In practice, the rear carriage receives the load while the front carriage is lifted over the obstacle for crossing. The load is then transferred from the rear carriage to the front carriage over the obstacle. Finally, the rear carriage is raised in turn over the obstacle, thus joining the front carriage and the load. This system is not entirely satisfactory, especially when the load is very heavy and / or very cumbersome. The operation is tiring and involves risks of injury, particularly related to the presence of the joint and the lifting of the carts.
Le but de la présente invention est de proposer un dispositif de manutention et un système de franchissement améliorés, permettant de franchir un obstacle au sol de manière performante, rapide et sécurisée.  The object of the present invention is to provide an improved handling device and a crossing system, allowing to cross a hurdle to the ground efficiently, quickly and securely.
A cet effet, l'invention a pour objet un dispositif de manutention, comprenant un châssis définissant un plan de référence et muni de moyens d'avance au sol, le plan de référence étant sensiblement parallèle au sol lorsque le dispositif repose au sol. Le dispositif de manutention est caractérisé en ce qu'il comprend également : un berceau creux comportant une surface supérieure adaptée pour recevoir au moins une charge ; un cadre mobile dans le berceau suivant un axe de translation non parallèle au plan de référence, cet axe étant de préférence perpendiculaire au plan de référence ; un mécanisme de transfert de la charge, le mécanisme étant solidaire du cadre en translation dans le berceau et délimitant un plan d'appui de la charge sensiblement parallèle au plan de référence ; et des moyens de déplacement du cadre dans le berceau suivant l'axe de translation, entre une configuration abaissée du dispositif, où le plan d'appui du mécanisme est situé au dessus de la surface supérieure du berceau, et une configuration relevée du dispositif, où le plan d'appui du mécanisme est situé au dessous de la surface supérieure du berceau. For this purpose, the invention relates to a handling device, comprising a frame defining a reference plane and provided with ground advance means, the reference plane being substantially parallel to the ground when the device rests on the ground. The handling device is characterized in that it also comprises: a hollow cradle having an upper surface adapted to receive at least one load; a moving frame in the cradle along a translation axis not parallel to the reference plane, this axis preferably being perpendicular to the reference plane; a mechanism for transferring the load, the mechanism being integral with the frame in translation in the cradle and delimiting a support plane of the load substantially parallel to the reference plane; and means for moving the frame in the cradle along the axis of translation, between a lowered configuration of the device, where the support plane of the mechanism is located above the upper surface of the cradle, and a raised configuration of the device, where the support plane of the mechanism is located below the upper surface of the cradle.
Ainsi, l'invention permet à un unique opérateur de transférer une charge par dessus un obstacle au sol rapidement, sans se fatiguer et de manière sécurisée. Une charge reçue par le dispositif de manutention repose sur la surface d'appui supérieure du berceau en configuration relevée, et sur le plan d'appui du mécanisme de transfert en configuration abaissée. De préférence, le mécanisme de transfert comprend des rouleaux de convoyage. En configuration relevée, le dispositif roulant au sol permet de déplacer une charge lourde et encombrante de manière simple et pratique, alors que la charge est immobilisée sur le berceau. En configuration abaissée, le dispositif est immobilisé au sol tandis que la charge peut coulisser sur le mécanisme de transfert.  Thus, the invention allows a single operator to transfer a load over a hurdle to the ground quickly, without getting tired and secure. A load received by the handling device is based on the upper support surface of the cradle in raised configuration, and on the support plane of the transfer mechanism in lowered configuration. Preferably, the transfer mechanism comprises conveying rollers. In the raised configuration, the device rolling on the ground makes it possible to move a heavy and bulky load in a simple and practical manner, while the load is immobilized on the cradle. In the lowered configuration, the device is immobilized on the ground while the load can slide on the transfer mechanism.
Selon d'autres caractéristiques avantageuses de l'invention, prises isolément ou en combinaison :  According to other advantageous features of the invention, taken separately or in combination:
- Le berceau comporte un bord supérieur et un bord inférieur tournés vers l'intérieur du berceau, respectivement au niveau de la surface supérieure et d'une surface inférieure du berceau, et le cadre est en butée dans le berceau, sélectivement, contre le bord supérieur en configuration abaissée ou contre le bord inférieur en configuration relevée.  - The cradle has an upper edge and a lower edge turned inwardly of the cradle, respectively at the upper surface and a lower surface of the cradle, and the frame is abutted in the cradle, selectively, against the edge upper in lowered configuration or against the lower edge in raised configuration.
- Le châssis, les moyens d'avance au sol et les moyens de déplacement du cadre dans le berceau appartiennent à un chariot transpalette.  - The frame, the ground advance means and the frame moving means in the cradle belong to a pallet truck.
- Le berceau, le support et le mécanisme de transfert forment un ensemble d'aide au franchissement d'obstacles au sol, cet ensemble coopérant par la seule gravité avec les moyens de déplacement.  - The cradle, the support and the transfer mechanism form a set of assistance to the crossing of obstacles on the ground, this assembly cooperating by gravity alone with the moving means.
- Les moyens de déplacement comprennent une fourche de levage au dessus de laquelle sont disposés le berceau et le cadre, avec un jeu ménagé entre la fourche et le berceau en configuration abaissée, et un contact entre la fourche et le berceau en configuration relevée. - Le cadre comprend au moins un pied s'étendant sous une surface inférieure du berceau, le ou les pieds étant sélectivement appuyés au sol en configuration abaissée ou écartés du sol en configuration relevée. - The moving means comprise a lifting fork over which are arranged the cradle and the frame, with a clearance between the fork and the cradle in lowered configuration, and a contact between the fork and the cradle in raised configuration. - The frame comprises at least one foot extending under a lower surface of the cradle, or the feet being selectively supported on the ground in the lowered configuration or spaced from the ground in raised configuration.
- Le ou les pieds traversent une ou des rainures ménagées dans la fourche.  - The foot or feet through one or grooves in the fork.
- Le mécanisme de transfert comprend au moins une rangée de rouleaux délimitant le plan d'appui de la charge en configuration abaissée.  - The transfer mechanism comprises at least one row of rollers defining the support plane of the load in lowered configuration.
L'invention a également pour objet un système de franchissement d'obstacles au sol. Ce système est caractérisé en ce qu'il comprend au moins deux dispositifs de manutention tels que mentionnés ci-dessus, disposés de part et d'autre d'un obstacle au sol.  The invention also relates to an obstacle clearance system on the ground. This system is characterized in that it comprises at least two handling devices as mentioned above, arranged on either side of an obstacle on the ground.
Le système de franchissement permet alors un transfert simple et rapide de la charge d'un mécanisme à l'autre. L'invention ne nécessite plus l'utilisation de palans et pitons pour franchir l'obstacle.  The crossing system then allows a simple and fast transfer of the load from one mechanism to another. The invention no longer requires the use of hoists and bolts to overcome the obstacle.
Avantageusement, le système de franchissement d'obstacles est tel qu'en configuration abaissée, les mécanismes de transfert de charge des deux dispositifs de manutention délimitent sensiblement un plan commun d'appui de la charge.  Advantageously, the obstacle clearance system is such that in lowered configuration, the load transfer mechanisms of the two handling devices substantially delimit a common load bearing plane.

Sur les figures 1 à 8 est représenté un dispositif de manutention 10 conforme à l'invention. Le dispositif 10 comprend un chariot transpalette 20 et un ensemble 50 d'aide au franchissement d'obstacles disposés sur un sol S. In Figures 1 to 8 is shown a handling device 10 according to the invention. The device 10 comprises a pallet truck 20 and an obstacle clearance assembly 50 arranged on a floor S.
Le chariot 20, connu en soi, comprend un châssis 22, des roues 24 mobiles en rotation par rapport au châssis 22 autour d'un axe Y24, un bloc 26 mobile en translation verticale par rapport au châssis 22, ainsi qu'une poignée de commande 28 reliée au châssis 22 par une tige 29.  The carriage 20, known per se, comprises a frame 22, wheels 24 rotatable relative to the frame 22 about an axis Y24, a block 26 movable in vertical translation relative to the frame 22, and a handle of control 28 connected to the frame 22 by a rod 29.
En pratique, un opérateur manipule la poignée 28 afin de commander le déplacement du chariot 20 au sol S, ainsi que la translation du bloc mobile 26 par rapport au châssis 22, sélectivement dans une direction D1 de montée ou dans une direction D2 de descente. A cet effet, la poignée 28 inclut des moyens de commande mécanique et/ou électrique, notamment un panneau de contrôle muni de différents boutons. En alternative ou en complément, le chariot 20 peut comprendre une télécommande et/ou un système de pilotage automatique.  In practice, an operator manipulates the handle 28 to control the movement of the carriage 20 to the ground S, as well as the translation of the movable block 26 relative to the frame 22, selectively in a rising direction D1 or in a descent direction D2. For this purpose, the handle 28 includes mechanical and / or electrical control means, in particular a control panel provided with different buttons. Alternatively or in addition, the carriage 20 may comprise a remote control and / or an automatic piloting system.
Pour faciliter le repérage des différentes parties du dispositif 10 dans l'espace, on définit un côté arrière où se place l'opérateur manipulant la poignée 28, un côté avant opposé à cette poignée 28 et vers lequel regarde habituellement l'opérateur, ainsi qu'un côté gauche et un côté droit. On définit également un axe X de déplacement du chariot 20 au sol S dans la direction avant ou arrière, un axe Z de déplacement du bloc 26 vers le haut suivant la direction D1 ou vers le bas suivant la direction D2, ainsi qu'un axe Y tel que les axes X, Y et Z forment un repère orthogonal.  In order to facilitate the identification of the various parts of the device 10 in the space, a rear side is defined where the operator handling the handle 28 is located, a front side opposite this handle 28 and towards which the operator usually looks, as well as one left side and one right side. An axis X of movement of the carriage 20 to the ground S in the front or rear direction, an axis Z of displacement of the block 26 upwards in the direction D1 or downwards along the direction D2, and an axis are also defined. Y such that the X, Y and Z axes form an orthogonal reference.
On définit également un plan de référence P10 associé au châssis 22, ce plan P10 étant sensiblement parallèle au sol S lorsque le dispositif 10 repose sur le sol S. Plus précisément, le plan P10 est défini comme étant le plan de la surface supérieure du châssis 22. Dans la configuration des figures 1 à 8, le plan P10 est parallèle aux axes X et Y et perpendiculaire à l'axe Z. On définit également les termes « horizontal », « vertical », « haut » et « bas » par rapport au plan P10 et au sol S. On définit également un plan médian Pm, qui est perpendiculaire aux axes Y et Z et constitue un plan de symétrie du dispositif 10.  A reference plane P10 associated with the frame 22 is also defined, this plane P10 being substantially parallel to the ground S when the device 10 rests on the ground S. More specifically, the plane P10 is defined as being the plane of the upper surface of the frame. 22. In the configuration of FIGS. 1 to 8, the plane P10 is parallel to the axes X and Y and perpendicular to the axis Z. The terms "horizontal", "vertical", "high" and "low" are also defined by relative to the plane P10 and to the ground S. We also define a median plane Pm, which is perpendicular to the axes Y and Z and constitutes a plane of symmetry of the device 10.
Le chariot 20 comprend une fourche 30 solidaire du bloc mobile 26. Cette fourche 30 comprend une branche gauche 32 et une branche droite 34 définissant ensemble une surface d'appui plane 36. Une rainure intérieure 38, ouverte vers le haut et vers le bas, est ménagée suivant l'axe X dans chaque branche 32 et 34.  The carriage 20 comprises a fork 30 secured to the movable block 26. This fork 30 comprises a left branch 32 and a straight branch 34 together defining a flat bearing surface 36. An inner groove 38, open upwards and downwards, is arranged along the X axis in each branch 32 and 34.
Le chariot 20 comprend également un système avant 40 d'appui et de roulement au sol S. Le système 40 est situé sous la fourche 30, vers l'avant du chariot 20. Le système 40 comprend une partie gauche 42 disposée sous la branche gauche 32 et une partie droite 44 disposée sous la branche droite 34. Chaque partie 42 ou 44 inclut une roulette 46 mobile en rotation autour d'un axe Y46 fixe par rapport à la fourche 30 et une roulette 48 mobile en rotation autour d'un axe Y48 mobile par rapport à la fourche 30. A cet effet, les roulettes 46 et 48 sont reliées par un levier 49 articulé, par rapport à la branche 32 ou 34, autour de l'axe Y46. Avantageusement, chaque partie 42 et 44 du système 40 comprend des moyens d'actionnement et/ou de blocage, non représentés, du levier 49, configurés pour accompagner le mouvement du levier 49 et/ou pour bloquer ce levier 49 dans différentes positions. The carriage 20 also comprises a front support system 40 and a bearing on the ground S. The system 40 is situated under the fork 30, toward the front of the carriage 20. The system 40 comprises a left part 42 arranged under the left branch. 32 and a straight portion 44 disposed under the straight leg 34. Each portion 42 or 44 includes a wheel 46 movable in rotation about a fixed axis Y46 relative to the fork 30 and a wheel 48 movable in rotation about a movable axis Y48 relative to the fork 30. For this purpose, the rollers 46 and 48 are connected by a lever 49 articulated, relative to the branch 32 or 34, about the axis Y46. Advantageously, each portion 42 and 44 of the system 40 comprises means for actuating and / or locking, not shown, of the lever 49, configured to accompany the movement of the lever 49 and / or to lock the lever 49 in different positions.
En alternative, le système 40 peut présenter une configuration différente, connue en soi dans le domaine des chariots transpalettes 20.  Alternatively, the system 40 may have a different configuration, known per se in the field of pallet trucks 20.
Les roues 24 et les roulettes 46 et 48 du système 40 constituent des moyens d'appui et d'avance au sol S du dispositif 10.  The wheels 24 and the rollers 46 and 48 of the system 40 constitute ground support and advance means S of the device 10.
L'ensemble 50 d'aide au franchissement d'obstacles au sol S comprend un berceau 60, un cadre 70 et des rouleaux 80 de convoyage. L'ensemble 50 est positionné au dessus de la fourche 30, de sorte que le berceau 60 puisse reposer sur la surface 36 de cette fourche 30. Dans un but de simplification, une charge C reçue par le dispositif 10, plus précisément par l'ensemble 50, est montrée seulement aux figures 7 à 9. Lorsque le dispositif 10 reçoit une ou plusieurs charges C à manutentionner, cette ou ces charges C reposent alors sélectivement sur le berceau 60 ou sur les rouleaux 80, comme détaillé ci- après. Chaque charge C peut être disposée sur le dispositif 10 par n'importe quel moyen connu en soi.  The assembly 50 for assistance in overcoming obstacles to the ground S comprises a cradle 60, a frame 70 and 80 conveyor rollers. The assembly 50 is positioned above the fork 30, so that the cradle 60 can rest on the surface 36 of this fork 30. For the sake of simplification, a load C received by the device 10, more precisely by the assembly 50, is shown only in FIGS. 7 to 9. When the device 10 receives one or more charges C to be handled, this or these charges C then rest selectively on the cradle 60 or on the rollers 80, as detailed below. Each charge C may be disposed on the device 10 by any means known per se.
Le berceau 60 présente une forme parallélépipédique, avec des parois planes rectangulaire qui sont perpendiculaires au plan de référence P10. Les parois de plus grande longueur du berceau 60 s'étendent suivant l'axe X, tandis que les parois de plus petite longueur s'étendent suivant l'axe Y, de sorte que le berceau 60 est creux et ouvert suivant l'axe Z. Les parois du berceau 60 forment une surface d'appui supérieure 62 et une surface d'appui inférieure 64. La surface 62 délimite un plan P60 d'appui supérieur adapté pour recevoir la charge C, tandis que la surface 64 est prévue pour reposer sur la surface 36 de la fourche 30. Un bord supérieur 66 et un bord inférieur 68 sont formés sur le pourtour du berceau 60, respectivement au niveau de la surface supérieure 62 et de la surface inférieure 64. Les bords 66 et 68 sont tournés vers l'intérieur du berceau 60, parallèlement au plan P10.  The cradle 60 has a parallelepipedal shape, with rectangular planar walls which are perpendicular to the reference plane P10. The walls of greater length of the cradle 60 extend along the axis X, while the walls of smaller length extend along the axis Y, so that the cradle 60 is hollow and open along the Z axis The walls of the cradle 60 form an upper bearing surface 62 and a lower bearing surface 64. The surface 62 defines an upper support plane P60 adapted to receive the load C, while the surface 64 is provided to rest. on the surface 36 of the fork 30. An upper edge 66 and a lower edge 68 are formed on the periphery of the cradle 60, respectively at the upper surface 62 and the lower surface 64. The edges 66 and 68 are facing inside the cradle 60, parallel to the plane P10.
Le cadre 70 est agencé dans le berceau 60. Plus précisément, le cadre 70 est mobile en translation suivant l'axe Z, dans la direction D1 ou D2, dans l'espace intérieur creux délimité entre les bords 66 et 68 et les parois du berceau 60. Le cadre 70 comprend des pieds 72, quatre barres longitudinales 73 et deux barres transversales 74. Les barres transversales 74 comportent des surfaces supérieures 76 et des surfaces inférieures 78. Lorsque le cadre 70 se translate dans le berceau 60 suivant la direction D1 , les surfaces 76 peuvent venir en appui contre les bords 66. Lorsque le cadre 70 se translate dans le berceau 60 suivant la direction D2, les surfaces 78 peuvent venir en appui contre les bords 68. The frame 70 is arranged in the cradle 60. More specifically, the frame 70 is movable in translation along the axis Z, in the direction D1 or D2, in the hollow interior space delimited between the edges 66 and 68 and the walls of the cradle 60. The frame 70 comprises legs 72, four longitudinal bars 73 and two transverse bars 74. The transverse bars 74 have upper surfaces 76 and lower surfaces 78. When the frame 70 is translated into the cradle 60 in the direction D1, the surfaces 76 can bear against the edges 66. When the frame 70 is translated into the cradle 60 in the direction D2, the surfaces 78 can bear against the edges 68.
Les rouleaux 80 sont disposés en deux rangées sur le cadre 70, à savoir une rangée de gauche 82 et une rangée de droite 84. Chaque rouleau 80 est mobile en rotation autour d'un axe Y80 parallèle à l'axe Y. A cet effet, chaque rouleau 80 est articulé en liaison pivot entre deux barres longitudinales 73 du cadre 70. Lorsque le cadre 70 vient buter contre les bords supérieurs 66, les rouleaux 80 dépassent au dessus de la surface 62, tandis que lorsque le cadre 70 repose sur les bords inférieurs 68, les rouleaux 80 sont logés dans le berceau 60. Les rouleaux 80 définissent un plan P80 d'appui supérieur adapté pour recevoir la charge C. Lorsque le plan P80 est au dessus du plan P60, la charge C peut rouler sur les rouleaux 80 et être transférée vers l'avant du dispositif 10.  The rollers 80 are arranged in two rows on the frame 70, namely a left row 82 and a right row 84. Each roll 80 is rotatable about an axis Y80 parallel to the axis Y. For this purpose each roller 80 is articulated in pivot connection between two longitudinal bars 73 of the frame 70. When the frame 70 abuts against the upper edges 66, the rollers 80 protrude above the surface 62, whereas when the frame 70 rests on the lower edges 68, the rollers 80 are housed in the cradle 60. The rollers 80 define a plane P80 upper support adapted to receive the load C. When the plane P80 is above the plane P60, the load C can roll on the rollers 80 and be transferred to the front of the device 10.
Le dispositif 10 est donc réglable entre une configuration abaissée 10A et une configuration relevée 10B. La configuration abaissée 10A est montrée aux figures 1 , 3, 5, 7 et 9, tandis que la configuration relevée 10B est montrée aux figures 2, 4, 6 et 8.  The device 10 is adjustable between a lowered configuration 10A and a raised configuration 10B. The lowered configuration 10A is shown in Figures 1, 3, 5, 7 and 9, while the raised configuration 10B is shown in Figures 2, 4, 6 and 8.
En configuration relevée 10B, le dispositif 10 est mobile au sol S afin de transporter la charge C. La fourche 30 est relevée par rapport au chariot 20 et au plan de référence P10. Le levier 49 est positionné verticalement, avec un écart horizontal e49 non nul entre les axes Y46 et Y48. Les roues 24 et les roulettes 48 sont en appui au sol S, permettant au chariot 20 de rouler. Les roulettes 46 et les pieds 72 du cadre 70 sont décollés du sol S. Le cadre 70 repose sur le berceau 60, qui lui-même repose sur la fourche 30. La surface 78 des barres 74 repose sur les bords 68 du berceau 60. Les rouleaux 80 sont logés dans le berceau 60 et dans les rainures 38 de la fourche 30. La charge C reçue par le dispositif 10 repose sur la surface supérieure 62 du berceau 60, qui joue alors le rôle de « palette » support de charge C.  In the raised configuration 10B, the device 10 is movable to the ground S to transport the load C. The fork 30 is raised relative to the carriage 20 and the reference plane P10. The lever 49 is positioned vertically, with a non-zero horizontal distance e49 between the axes Y46 and Y48. The wheels 24 and the rollers 48 are supported on the ground S, allowing the carriage 20 to roll. The rollers 46 and the legs 72 of the frame 70 are detached from the ground S. The frame 70 rests on the cradle 60, which itself rests on the fork 30. The surface 78 of the bars 74 rests on the edges 68 of the cradle 60. The rollers 80 are housed in the cradle 60 and in the grooves 38 of the fork 30. The load C received by the device 10 rests on the upper surface 62 of the cradle 60, which then acts as a "pallet" load support C .
En configuration abaissée 10A, le dispositif 10 est immobilisé par rapport au sol S, tandis que la charge C est mobile sur les rouleaux 80. La fourche 30 est abaissée par rapport au chariot 20 et au plan de référence P10. Les pieds 72 du cadre 70 reposent sur le sol S, de même que les roues 24 et les roulettes 46 et 48. Le berceau 60 repose sur le cadre 70, en étant écarté verticalement de la fourche 30. Plus précisément, un jeu j64 est ménagé suivant l'axe Z entre les surfaces 36 et 64, tandis que le bord 66 est en appui sur la surface 76. Un jeu j62 est alors ménagé suivant l'axe Z au niveau de la surface 62, entre le plan P60 et le P80. Autrement dit, les rouleaux 80 dépassent au dessus du berceau 60, de sorte que la charge C reçue par le dispositif 10 repose sur les rouleaux 80. La rotation d'axe Y80 des rouleaux 80 permet la translation de la charge C suivant l'axe X sur le plan P80. In the lowered configuration 10A, the device 10 is immobilized relative to the ground S, while the load C is movable on the rollers 80. The fork 30 is lowered relative to the carriage 20 and to the reference plane P10. The feet 72 of the frame 70 rest on the ground S, as well as the wheels 24 and the rollers 46 and 48. The cradle 60 rests on the frame 70, being spaced vertically from the fork 30. More specifically, a game j64 is arranged along the Z axis between the surfaces 36 and 64, while the edge 66 bears on the surface 76. A clearance j62 is then formed along the Z axis at the surface 62, between the plane P60 and the P80. In other words, the rollers 80 protrude above the cradle 60, so that the load C received by the device 10 rests on the rollers 80. The rotation of axis Y80 of the rollers 80 allows the translation of the load C along the X axis on the plane P80.
A ce stade, on remarque que l'ensemble 50 peut être adapté à tout type de chariot 20, de préférence du type chariot transpalette. Les éléments constitutifs 50, 60 et 70 de cet ensemble 50 sont solidaires, avec des mobilités particulières prévues entre eux. Lorsque le dispositif 10 est en configuration abaissée 10A, l'ensemble 50 peut être solidarisé ou désolidarisé du chariot 20, plus précisément de la fourche 30, les pieds 72 étant alors logés dans les rainures 38. Lorsque le dispositif 10 est en configuration relevée 10B, la fourche 20 et l'ensemble 50 sont solidarisés et coopèrent par la seule gravité, sans nécessiter d'organes additionnels de fixation du type vis ou boulons.  At this stage, it is noted that the assembly 50 can be adapted to any type of carriage 20, preferably of the pallet truck type. The constituent elements 50, 60 and 70 of this assembly 50 are integral, with particular mobility provided between them. When the device 10 is in the lowered configuration 10A, the assembly 50 can be secured or disengaged from the carriage 20, more precisely from the fork 30, the feet 72 then being housed in the grooves 38. When the device 10 is in raised configuration 10B , the fork 20 and the assembly 50 are secured and cooperate by gravity alone, without the need for additional fasteners such as screws or bolts.
En variante non représentée, l'ensemble 50 peut être configuré de manière différente. Par exemple, les rouleaux 80 peuvent présenter un nombre différent de rangées 82 et 84. Selon une autre variante, l'ensemble 50 peut comprendre un mécanisme de transfert de charge C autre que les rouleaux 80, notamment un tapis roulant sans fin, délimitant une surface d'appui sensiblement horizontale. Selon une autre variante, le cadre 70 est mobile dans le berceau 60 suivant un axe incliné par rapport au plan de référence P10 et à l'axe vertical Z. Autrement dit, l'ensemble 50 peut présenter différentes modifications structurelles sans sortir du cadre de l'invention.  In variant not shown, the assembly 50 can be configured differently. For example, the rollers 80 may have a different number of rows 82 and 84. In another variant, the assembly 50 may comprise a load transfer mechanism C other than the rollers 80, in particular an endless conveyor belt, defining a substantially horizontal bearing surface. According to another variant, the frame 70 is movable in the cradle 60 along an inclined axis with respect to the reference plane P10 and to the vertical axis Z. In other words, the assembly 50 may have different structural modifications without departing from the scope of FIG. the invention.
Sur la figure 9 est représenté un système 100, conforme à l'invention, de franchissement d'obstacles E au sol S.  FIG. 9 shows a system 100, according to the invention, for clearing obstacles E on the ground S.
Le système 100 comprend deux dispositifs de manutention 10 et 10'. Le dispositif 10' est identique au dispositif 10 décrit plus haut. Ce dispositif 10' comprend notamment un chariot 20', une fourche 30', un ensemble 50' et des rouleaux 80' qui sont identique respectivement au chariot 20, à la fourche 30, à l'ensemble 50 et aux rouleaux 80 du dispositif 10.  The system 100 comprises two handling devices 10 and 10 '. The device 10 'is identical to the device 10 described above. This device 10 'comprises in particular a carriage 20', a fork 30 ', an assembly 50' and rollers 80 'which are identical to the carriage 20, the fork 30, the assembly 50 and the rollers 80 of the device 10 respectively. .
Les dispositifs 10 et 10' du système 100 sont situés de part et d'autre de l'obstacle E, chacun reposant au sol S d'un côté de cet obstacle E. En particulier, l'obstacle E peut être un surbau de porte D étanche de navire. Le système 100 est néanmoins adapté au franchissement de tout type d'obstacle E au sol S. Les chariots 20 et 20' appartenant aux dispositifs 10 et 10' peuvent être configurés en fonction de la hauteur de l'obstacle E à franchir, tandis que les ensembles 50 et 50' sont adaptés à tout type d'application de franchissement d'obstacle E au sol S.  The devices 10 and 10 'of the system 100 are located on either side of the obstacle E, each resting on the ground S on one side of this obstacle E. In particular, the obstacle E can be a door sill D watertight ship. The system 100 is nevertheless adapted to the crossing of any type of obstacle E to the ground S. The carriages 20 and 20 'belonging to the devices 10 and 10' can be configured according to the height of the obstacle E to be crossed, while the assemblies 50 and 50 'are adapted to any type of obstacle clearance application E to the ground S.
En pratique, dans un premier temps, l'opérateur aligne les dispositifs 10 et 10' en configuration relevée 10B suivant l'axe X, de part et d'autre de l'obstacle E. De préférence mais non obligatoirement, l'extrémité avant de chaque fourche 30 et 30' peut être munie d'organes amortisseurs, non représentés, de manière à venir en butée contre l'obstacle E. Sinon, l'opérateur doit faire en sorte que les fourches 30 et 30' ne butent pas contre l'obstacle E. Ensuite, l'opérateur actionne les dispositifs 10 et 10' de la configuration relevée 10B vers la configuration abaissée 10A. A ce stade, les rouleaux 80 et 80' sont positionnés de manière à présenter un plan d'appui P80 commun. La charge C peut alors rouler sur ce plan P80, depuis les rouleaux 80 du dispositif 10 vers les rouleaux 80' du dispositif 10', suivant un mouvement de transfert représenté par la flèche F1 à la figure 9. In practice, in a first step, the operator aligns the devices 10 and 10 'in raised configuration 10B along the X axis, on either side of the obstacle E. Preferably, but not necessarily, the front end each fork 30 and 30 'may be provided with damping members, not shown, so as to abut against the obstacle E. Otherwise, the operator must ensure that the forks 30 and 30 'do not abut against the obstacle E. Then, the operator actuates the devices 10 and 10' of the raised configuration 10B to the lowered configuration 10A. At this stage, the rollers 80 and 80 'are positioned so as to have a common support plane P80. The load C can then roll on this plane P80, from the rollers 80 of the device 10 to the rollers 80 'of the device 10', according to a transfer movement represented by the arrow F1 in FIG. 9.
Ainsi, l'opérateur peut transférer la charge C par-dessus l'obstacle E avec un effort réduit, puis utiliser le dispositif 10' pour transporter la charge C de l'autre côté de cet obstacle E.  Thus, the operator can transfer the load C over the obstacle E with reduced effort, then use the device 10 'to carry the load C on the other side of this obstacle E.
L'invention est adaptée à la manutention de charges dans les navires, mais également dans les entrepôts, sur les chantiers et pour tout type d'application de manutention.  The invention is suitable for handling loads in ships, but also in warehouses, on construction sites and for any type of handling application.
