Description

La présente invention concerne un dispositif de manutention de charge, du type manipulable à l'aide d'un chariot élévateur à fourche, selon le préambule de la revendication 1. Un tel dispositif est connu du AU 31387/77A .The present invention relates to a load handling device, of the manipulable type using a forklift, according to the preamble of claim 1. Such a device is known from AU 31387 / 77A .

Elle concerne plus particulièrement un dispositif de manutention de charge comprenant au moins une structure support de charge délimitant au moins deux surfaces d'appui de la charge formant sensiblement un angle droit entre elles, et couplable à ladite structure support, au moins un passage, dit passage de fourche, à l'intérieur duquel sont aptes à s'engager les dents de la fourche du chariot en vue d'un déplacement en monte et baisse de la structure support à l'aide dudit chariot.It relates more particularly to a load handling device comprising at least one load bearing structure delimiting at least two support surfaces of the load forming substantially a right angle between them, and couplable to said support structure, at least one passage, said fork passage, inside which are adapted to engage the teeth of the fork of the carriage for a movement upward and downward of the support structure with the aid of said carriage.

De tels dispositifs sont bien connus à ceux versés dans cet art et permettent la manutention d'un grand nombre de charges. On constate toutefois que certaines charges, telles que les panneaux, en particulier des plaques de plâtre ou autres panneaux de construction, qui sont stockés à plat en palettes, doivent, pour leur chargement par exemple dans le camion d'un poseur, être amenés sur chant avant d'être embarqués dans ledit camion. Cette position sur chant facilite les opérations de chargement et de déchargement. L'opérateur doit de ce fait prendre chaque plaque ou panneau de la palette, la manipuler pour l'amener d'une position de stockage à plat à une position de stockage sur chant avant de la charger dans son véhicule. Il en résulte une perte de temps importante et une manipulation fastidieuse.Such devices are well known to those skilled in the art and allow the handling of a large number of loads. However, it is noted that some loads, such as panels, especially plasterboard or other building panels, which are stored flat in pallets, must, for their loading for example in the truck of a poser, be brought on singing before being loaded into the truck. This singing position facilitates loading and unloading operations. The operator must therefore take each plate or panel of the pallet, manipulating it to bring it from a flat storage position to a storage position on edge before loading it into his vehicle. This results in a significant loss of time and tedious handling.

Un but de la présente invention est donc de proposer un dispositif de manutention de charge dont la conception permet le passage rapide d'une position de stockage suivant une première orientation, telle qu'un stockage à plat de la charge, à une position suivant une deuxième orientation, telle qu'un stockage sur chant de la charge.An object of the present invention is therefore to provide a load handling device whose design allows the rapid passage of a storage position according to a first orientation, such as a flat storage of the load, at a position following a second orientation, such as a storage on the edge of the load.

Un autre but de la présente invention est de proposer un dispositif de manutention de charge dont la conception permet, à l'aide d'un même passage de fourche, de manipuler plusieurs structures support de charge.Another object of the present invention is to provide a load handling device whose design allows, using a single forklift, to manipulate several load bearing structures.

A cet effet, l'invention a pour objet un dispositif de manutention de charge, du type manipulable à l'aide d'un chariot élévateur à fourche, le dispositif comprenant au moins une structure support de charge délimitant au moins deux surfaces d'appui de la charge formant sensiblement un angle droit entre elles, et couplable à ladite structure support de charge, au moins un passage, dit passage de fourche, à l'intérieur duquel sont aptes à s'engager les dents de la fourche du chariot en vue d'un déplacement de la structure support à l'aide dudit chariot, caractérisé en ce que le, ou au moins l'un des, passage(s) de fourche s'étend, à l'état couplé à la structure support, en prolongement de l'une des branches du L formé par lesdites surfaces d'appui et est relié à l'extrémité libre de ladite branche par une liaison pivot d'axe orthogonal à l'axe longitudinal desdites branches de manière à permettre, parallèlement au déplacement du passage de fourche à l'aide du chariot élévateur, le déplacement à pivotement de la structure support et le passage de ladite structure support d'une position de stockage horizontal, ou respectivement vertical, de la charge, à l'aide de la surface d'appui articulée au passage de fourche, dite première surface d'appui, à une position de stockage vertical, ou respectivement horizontal, de la charge, à l'aide de l'autre surface d'appui, dite deuxième surface d'appui.For this purpose, the subject of the invention is a load-handling device of the manipulable type using a forklift truck, the device comprising at least one load-bearing structure delimiting at least two bearing surfaces. the load forming substantially a right angle between them, and couplable to said load support structure, at least one passage, said passage of fork, inside which are adapted to engage the teeth of the fork of the carriage in order to a displacement of the support structure using said carriage, characterized in that the, or at least one of the fork passage (s) extends, in the state coupled to the support structure, in extension of one of the branches of L formed by said bearing surfaces and is connected to the free end of said branch by a pivot link axis orthogonal to the longitudinal axis of said branches so as to allow, parallel to the displacement the forklift using the forklift, the pivotal displacement of the support structure and the passage of said support structure from a horizontal or vertical storage position of the load, with the aid of the articulated support surface at the forklift, said first bearing surface, at a vertical storage position, or horizontal, respectively, the load, with the aid of the other bearing surface, said second bearing surface.

Grâce à la présence de la liaison articulée entre passage de fourche et structure support, l'opérateur peut, par simple mouvement de montée ou descente du passage de fourche à l'aide du chariot élévateur, modifier la position d'appui au sol de la structure support et par suite, l'orientation de la charge en appui sur la structure support et permettre ainsi, en quelques secondes, le passage d'une charge d'un stockage dit horizontal à un stockage vertical ou inversement.Thanks to the presence of the articulated connection between the forklift and the support structure, the operator can, by simply raising or lowering the forklift using the forklift, modify the ground support position of the forklift. support structure and consequently, the orientation of the load resting on the support structure and thus allow, in a few seconds, the passage of a load of so-called horizontal storage vertical storage or vice versa.

Dans un premier mode de réalisation de l'invention, la liaison pivot entre passage de fourche et structure support de charge est une liaison non permanente formée de moyens de liaison portés respectivement par le passage de fourche et la structure support, lesdits moyens de liaison étant couplables/désaccouplables entre eux.In a first embodiment of the invention, the pivot connection between the fork passage and the load support structure is a non-permanent link formed by connection means carried respectively by the fork passage and the support structure, said connecting means being couplable / uncouplable between them.

Grâce au fait que la liaison pivot entre passage de fourche et structure support est une liaison non permanente du type dans laquelle les moyens de liaison portés respectivement par le passage de fourche et la structure support sont couplables/désacouplables l'un de l'autre pour permettre une séparation du passage de fourche de la structure support, il est possible, à l'aide d'un même passage de fourche, de manipuler plusieurs structures support. Il en résulte une économie en termes d'équipement.Thanks to the fact that the pivot connection between the fork passage and the support structure is a non-permanent connection of the type in which the connecting means carried respectively by the fork passage and the support structure are couplable / disengageable from one another to to allow a separation of the forklift of the support structure, it is possible, using a same forklift, to manipulate several support structures. This results in a saving in terms of equipment.

Dans un second mode de réalisation de l'invention, la liaison pivot entre passage de fourche et structure support de charge est une liaison permanente non démontable.In a second embodiment of the invention, the pivot connection between the fork passage and the load-bearing structure is a non-removable permanent connection.

Indépendamment du mode de réalisation retenu, le passage de fourche, apte à être couplé à la structure support, est formé de deux tunnels maintenus parallèles entre eux, lesdits tunnels étant, au niveau de l'une de leurs extrémités, couplables ou couplés par ladite liaison pivot à la première surface d'appui, en particulier au bord libre de ladite surface d'appui opposé à la zone de jonction desdites surfaces d'appui entre elles, la liaison entre première surface d'appui et passage de fourche étant une liaison pivot d'axe parallèle à la ligne de jonction desdites surfaces d'appui entre elles et orthogonal à l'axe longitudinal desdits tunnels.Regardless of the embodiment chosen, the fork passage, capable of being coupled to the support structure, is formed of two tunnels kept parallel to one another, said tunnels being, at one of their ends, couplable or coupled by said pivot connection to the first bearing surface, in particular to the free edge of said bearing surface opposite to the junction zone of said bearing surfaces therebetween, the connection between the first bearing surface and the fork passage being a connection axis pivot parallel to the line of junction of said bearing surfaces therebetween and orthogonal to the longitudinal axis of said tunnels.

Dans le mode de réalisation du type dans lequel la liaison pivot entre passage de fourche et structure support de charge est une liaison non permanente, le passage de fourche apte à être couplé à la structure support par une liaison pivot est, côté introduction des dents de la fourche du chariot élévateur à l'intérieur du passage de fourche, équipé de moyens de retenue des dents de la fourche du chariot à l'intérieur dudit passage de fourche.In the embodiment of the type in which the pivot connection between the fork passage and the load bearing structure is a non-permanent connection, the fork passage adapted to be coupled to the support structure by a pivot connection is, on the insertion side of the the fork of the forklift to the inside of the fork passage, equipped with means for retaining the teeth of the fork of the carriage inside said fork passage.

Ces moyens de retenue évitent toute sortie intempestive des dents de la fourche du chariot élévateur du passage de fourche articulé lorsque le passage de fourche occupe une position écartée de sa position d'appui au sol.These retaining means prevent untimely exit of the teeth of the forklift fork of the articulated fork passage when the fork passage occupies a position away from its ground support position.

De préférence, les moyens de retenue affectent la forme d'au moins un volet mobile apte à passer, sous l'effet de son propre poids, d'une position inactive, dans laquelle il libère l'entrée dudit passage de fourche par laquelle les dents de la fourche du chariot élévateur sont aptes à être introduites ou sorties dudit passage de fourche à une position active, dans laquelle il ferme l'entrée du passage de fourche et est apte à retenir les dents de la fourche du chariot élévateur à l'intérieur du passage de fourche.Preferably, the retaining means affect the shape of at least one movable flap adapted to pass, under the effect of its own weight, an inactive position, in which it releases the input of said fork passage by which the teeth of the fork of the forklift are adapted to be introduced or outputs of said fork passage to an active position, in which it closes the entrance of the fork passage and is adapted to retain the teeth of the fork of the forklift to the inside the forklift.

De même, la structure support comporte des moyens de maintien de la charge sur ladite structure support.Similarly, the support structure comprises means for maintaining the load on said support structure.

Enfin, généralement, le dispositif de manutention de charge comprend un deuxième passage de fourche disposé fixe par rapport aux surfaces d'appui de ladite structure support.Finally, generally, the load handling device comprises a second fork passage disposed fixed relative to the bearing surfaces of said support structure.

Comme mentionné ci-dessus, le dispositif de manutention de charge, objet de l'invention, est plus particulièrement destiné à être manipulé à l'aide d'un chariot élévateur à fourche dont seule la fourche 20 a été représentée.As mentioned above, the load handling device, object of the invention, is more particularly intended to be handled using a forklift fork which only the fork 20 has been shown.

Ce dispositif de manutention s'applique plus particulièrement à la manutention de charges, telles que panneaux ou plaques, stockées soit à plat en palette et devant en particulier pour leur chargement dans un véhicule être stockées sur chant, soit stockées sur chant et devant être amenées dans une position de stockage à plat.This handling device is more particularly applicable to the handling of loads, such as panels or plates, stored either flat pallet and before especially for their loading in a vehicle to be stored on edge, or stored on edge and to be brought in a flat storage position.

Ce dispositif de manutention de charge 1 comprend au moins une structure 2 support de charge délimitant au moins deux surfaces 3,4 d'appui de la charge 1 formant sensiblement un angle droit entre elles et, couplable à ladite structure 2 support de charge, au moins un passage 12 de fourche à l'intérieur duquel sont aptes à s'engager les dents de la fourche du chariot. Il doit être noté que les surfaces 3, 4 d'appui de la charge de la structure de support forment entre elles un angle compris de préférence entre 80 et 120°. De préférence, l'angle est un angle ouvert supérieur à 90° pour permettre à la charge, en position de stockage sur chant de la charge, de reposer par son chant sur l'une des deux surfaces d'appui et par l'une de ses faces sur l'autre surface d'appui dans une position inclinée limitant les risques de chute de la charge.This load handling device 1 comprises at least one load bearing structure 2 delimiting at least two support surfaces 3,4 of the load 1 forming substantially a right angle between them and, coupled to said load support structure 2, minus a passage 12 of fork inside which are adapted to engage the teeth of the fork of the carriage. It should be noted that the support surfaces 3, 4 of the load of the support structure form between them an angle of preferably between 80 and 120 °. Preferably, the angle is an open angle greater than 90 ° to allow the load, in the position of storage on edge of the load, to rest by its edge on one of the two bearing surfaces and by one its faces on the other bearing surface in an inclined position limiting the risk of falling of the load.

Dans les exemples représentés, le passage 12 de fourche est quant à lui formé de deux tunnels 13 maintenus en disposition parallèle à l'aide d'au moins une traverse 14 reliant les tunnels entre eux, chaque tunnel 13 servant à accueillir une dent du chariot élévateur à fourche.In the examples shown, the passage 12 fork is itself formed of two tunnels 13 maintained in parallel arrangement with the aid of at least one cross 14 connecting the tunnels between them, each tunnel 13 for accommodating a tooth of the carriage forklift.

De manière caractéristique à l'invention, le ou au moins l'un des passages de fourche, représenté en 12 aux figures, s'étend en prolongement de l'une des branches du L formé par lesdites surfaces 3, 4 d'appui et est relié à l'extrémité libre de ladite branche par une liaison 5 pivot d'axe orthogonal à l'axe longitudinal desdites branches de manière à permettre, parallèlement au déplacement du passage 12 de fourche à l'aide du chariot élévateur, le déplacement à pivotement de la structure 2 support et le passage de la structure 2 support d'une position de stockage horizontal, ou respectivement vertical, de la charge 1, à l'aide de la surface 3 d'appui articulée au passage 12 de fourche, dite première surface 3 d'appui, à une position de stockage vertical, ou respectivement horizontal, de la charge 1, à l'aide de l'autre surface 4 d'appui dite deuxième surface 4 d'appui. Ainsi, les figures 9A, 9C ou 1 et 2 illustrent le passage d'une charge d'une position dans laquelle elle est formée d'un empilement de plaques stockées à plat à une position dans laquelle elle forme une juxtaposition de plaques stockées sur chant, ce passage d'une position à une autre de la charge étant obtenu par simple élévation du passage de fourche qui entraîne en parallèle le déplacement à pivotement de la structure 2 support. Dans les exemples représentés aux figures 9A, 9C ou 1 et 2, la structure 2 support tend à pivoter autour du sommet de l'angle sensiblement droit formé par lesdites surfaces 3, 4 d'appui qui constitue un point d'appui au sol de ladite structure 2 support au cours de son entraînement en déplacement par le passage 12 de fourche. Ainsi, la structure 2 support passe d'une position dans laquelle la surface 3 d'appui articulée au passage 12 de fourche et dite première surface d'appui repose au sol et forme un plateau support de charge à une position dans laquelle c'est la surface 4 d'appui, dite deuxième surface d'appui, de la structure 2 support qui repose au sol et forme un plateau support de la charge. Bien évidemment, un déplacement inverse de la structure 2 support est observé lors d'un abaissement du passage 12 de fourche à l'aide du chariot élévateur.In characteristic manner to the invention, the or at least one of the fork passages, represented at 12 in the figures, extends in extension of one of the branches of the L formed by said bearing surfaces 3, 4 and is connected to the free end of said branch by a pivot link 5 of axis orthogonal to the axis longitudinal of said branches so as to allow, parallel to the displacement of the fork passage 12 with the aid of the lift truck, the pivotal displacement of the support structure 2 and the passage of the support structure 2 from a horizontal storage position, or respectively vertical, of the load 1, with the support surface 3 articulated to the fork passage 12, said first bearing surface 3, at a vertical storage position, or horizontal, respectively, of the load 1, using the other support surface 4 said second bearing surface 4. Thus, Figures 9A, 9C or 1 and 2 illustrate the passage of a load from a position in which it is formed of a stack of plates stored flat to a position in which it forms a juxtaposition of plates stored on edge, this passage from one position to another of the load being obtained by simple elevation of the fork passage which drives in parallel the pivotal movement of the support structure 2. In the examples shown in Figures 9A, 9C or 1 and 2 , the support structure 2 tends to pivot about the vertex of the substantially straight angle formed by said bearing surfaces 3, 4 which constitutes a point of support on the ground of said support structure 2 during its driving in displacement by the fork passage 12. Thus, the support structure 2 passes from a position in which the bearing surface 3 articulated to the fork passage 12 and said first bearing surface rests on the ground and forms a load support plate at a position in which it is the support surface 4, said second bearing surface, of the support structure 2 which rests on the ground and forms a support plate of the load. Of course, a reverse displacement of the support structure 2 is observed during a lowering of the fork passage 12 with the aid of the forklift.

Dans un premier mode de réalisation de l'invention, conforme aux figures 1 à 6, la liaison 5 pivot entre passage 12 de fourche et structure 2 support de charge est une liaison 5 non permanente formée de moyens de liaison portés respectivement par le passage 12 de fourche et la structure 2 support, lesdits moyens 15, 8 de liaison étant couplables/désaccouplables entre eux, pour permettre à l'état désaccouplé, notamment, une utilisation du passage 12 de fourche avec une autre structure 2 support.In a first embodiment of the invention, in accordance with Figures 1 to 6 , the pivot connection between the fork passage 12 and the load support structure 2 is a non-permanent link 5 formed of connecting means carried respectively by the fork passage 12 and the support structure 2, the connecting means 15 and 8 being couplable. / uncoupling them, to allow the uncoupled state, including a use of the passage 12 of fork with another structure 2 support.

Comme mentionné ci-dessus, le passage 12 de fourche, apte à être couplé à la structure 2 support, est formé de deux tunnels 13 maintenus parallèles entre eux, lesdits tunnels 13 étant, au niveau de l'une de leurs extrémités, équipés des moyens 15 de liaison du passage 12 de fourche pour la liaison 5 pivot à la première surface 3 d'appui, en particulier au bord libre de ladite surface d'appui opposé à la zone de jonction desdites surfaces 3, 4 d'appui entre elles, la liaison non permanente entre première surface 3 d'appui et passage 12 de fourche étant une liaison 5 pivot d'axe parallèle à la ligne de jonction desdites surfaces 3, 4 d'appui entre elles et orthogonal à l'axe longitudinal desdits tunnels.As mentioned above, the fork passage 12, capable of being coupled to the support structure 2, is formed of two tunnels 13 held parallel to each other, said tunnels 13 being, at one of their ends, equipped with means 15 for connecting the fork passage 12 for the pivot link 5 to the first bearing surface 3, in particular at the free edge of said bearing surface opposite to the junction zone of said bearing surfaces 3, 4 between them , the non-permanent connection between the first support surface 3 and the fork passage 12 being a pivot link with axis parallel to the line of junction of said bearing surfaces 3, 4 between them and orthogonal to the longitudinal axis of said tunnels .

Dans les exemples représentés, la liaison 5 pivot non permanente entre la première surface 3 d'appui de la structure 2 support et le passage 12 de fourche couplable à ladite première surface 3 d'appui est une liaison du type par crochetage.In the examples shown, the non-permanent pivot connection 5 between the first bearing surface 3 of the support structure 2 and the fork passage 12 that is couplable to said first bearing surface 3 is a hook-type connection.

Dans ce mode de réalisation du dispositif de manutention de charge 1, du type dans lequel la liaison 5 pivot entre passage 12 de fourche et structure 2 support est une liaison non permanente et la première surface 3 d'appui de la structure 2 support est formée au moins de deux longerons 7 maintenus parallèles entre eux par l'intermédiaire de traverses 8, pour le couplage par liaison 5 pivot entre la première surface 3 d'appui de la structure 2 support et le passage 12 de fourche, les tunnels 13 constitutifs du passage 12 de fourche sont munis, au niveau de l'une de leurs extrémités, d'au moins un crochet 15 apte à venir en prise avec l'une des traverses 8 de la première surface 3 d'appui de la structure 2 support, crochet(s) 15 et traverse 8 formant les moyens 15, 8 de liaison portés respectivement par le passage 12 de fourche et la structure 2 support.In this embodiment of the load handling device 1, of the type in which the pivot connection between the fork passage 12 and the support structure 2 is a non-permanent connection and the first support surface 3 of the support structure 2 is formed. at least two longitudinal members 7 held parallel to each other by means of sleepers 8, for coupling 5 pivot connection between the first bearing surface 3 of the support structure 2 and the fork passage 12, the tunnels 13 constituting the fork passage 12 are provided, at one of their ends, with at least one hook 15 adapted to engage one of the cross members 8 of the first support surface 3 of the support structure 2, hook (s) 15 and cross 8 forming the connecting means 15, 8 carried respectively by the passage 12 of the fork and the support structure 2.

Les crochets sont ici des crochets en forme générale de U couché ouverts en direction des extrémités des tunnels 13 qui les portent. La traverse 8 est quant à elle formée par une simple barre de section circulaire reliant entre eux les deux longerons 7 de la première surface 3 d'appui de la structure 2 support. Les crochets 15 du passage 12 de fourche sont aptes à venir en prise avec la traverse 8 de la structure 2 support par manipulation, à l'aide du chariot élévateur, du passage 12 de fourche sans que le conducteur du chariot à fourche n'ait à descendre de son engin. Ce couplage/désaccouplage entre structure 2 support et passage 12 de fourche peut s'opérer indifféremment en position d'appui au sol ou en position écartée du sol du passage 12 de fourche.The hooks here are hooks in the general shape of U lying open in direction of the ends of the tunnels 13 which carry them. The crossbar 8 is itself formed by a simple bar of circular section interconnecting the two longitudinal members 7 of the first bearing surface 3 of the support structure 2. The hooks 15 of the fork passage 12 are able to engage the cross member 8 of the support structure 2 by manipulation, with the aid of the forklift, of the fork passage 12 without the forklift driver having to get off his gear. This coupling / uncoupling between support structure 2 and fork passage 12 can be carried out indifferently in the ground support position or in a position away from the ground of the fork passage 12.

Dans les exemples représentés, le passage 12 de fourche, apte à être couplé à la structure 2 support par une liaison 5 pivot est, côté introduction des dents de la fourche 20 du chariot élévateur à l'intérieur du passage 12 de fourche, équipé de moyens de retenue des dents de la fourche 20 du chariot à l'intérieur dudit passage 12 de fourche.In the examples shown, the fork passage 12, which can be coupled to the support structure 2 by a pivot connection, is, on the insertion side, of the fork fork 20 teeth inside the fork passage 12, equipped with means for retaining the teeth of the fork 20 of the carriage inside said fork passage 12.

Les moyens de retenue affectent la forme d'au moins un volet 16 mobile apte à passer, sous l'effet de son propre poids, d'une position inactive, dans laquelle il libère l'entrée dudit passage 12 de fourche par laquelle les dents de la fourche du chariot élévateur sont aptes à être introduites ou sorties dudit passage 12 de fourche à une position active, dans laquelle il ferme l'entrée du passage 12 de fourche et est apte à retenir les dents de la fourche 20 du chariot élévateur à l'intérieur du passage 12 de fourche.The retaining means affect the shape of at least one movable flap 16 able to pass, under the effect of its own weight, an inactive position, in which it releases the inlet of said fork passage 12 through which the teeth fork of the forklift fork are adapted to be introduced or out of said fork passage 12 to an active position, in which it closes the inlet of the fork passage 12 and is adapted to retain the teeth of the fork 20 of the forklift inside the forkway 12.

En particulier, le volet 16 mobile est un volet pivotant, monté à pivotement autour d'un axe 17 parallèle à l'axe pivot de la liaison 5 pivot entre passage 12 de fourche et structure 2 support, ledit volet 16 étant apte à passer, sous l'effet de son propre poids, de la position inactive à la position active, lors du déplacement du passage 12 de fourche à l'aide du chariot élévateur dans le sens d'une élévation dudit passage 12 de fourche depuis sa position d'appui au sol.In particular, the movable flap 16 is a pivoting flap, pivotally mounted about an axis 17 parallel to the pivot axis of the link 5 pivot between fork passage 12 and support structure 2, said flap 16 being adapted to pass, under the effect of its own weight, from the inactive position to the active position, during the displacement of the fork passage 12 with the forklift in the direction of an elevation of said fork passage 12 from its position of ground support.

Le détail de ce volet 16 pivotant est plus particulièrement visible aux figures 3 et 4. Ce volet 16 disposé sur le passage 12 de fourche au niveau des extrémités de tunnels 13 opposées à celles équipées des moyens 15 de liaison du passage 12 de fourche à la structure 2 support ferme donc, en position active, les entrées des tunnels 13 du passage 12 de fourche. Ce volet est rappelé dans cette position active par des moyens 18 de lestage équipant ledit volet, ces moyens de lestage étant actifs lorsque le passage 12 de fourche ne repose pas au sol. Ces moyens de lestage tendent à faire pivoter le volet 16 autour de son axe 17 de pivotement. L'appui au sol du passage 12 de fourche agit à l'encontre des moyens de lestage et entraîne un déplacement à pivotement du volet 16 autour de son axe pivot 17 jusqu'à une position dans laquelle le volet 16 libère l'accès à l'entrée des tunnels 13.The detail of this pivoting flap 16 is more particularly visible to figures 3 and 4 . This flap 16 disposed on the fork passage 12 at the ends of tunnels 13 opposite those equipped with means 15 for connecting the passage 12 of the fork to the support structure 2 therefore closes, in the active position, the entrances of the tunnels 13 of the passage 12 fork. This flap is recalled in this active position by ballasting means 18 equipping said flap, these weighting means being active when the passage 12 fork does not rest on the ground. These ballasting means tend to pivot the flap 16 about its pivot axis 17. The ground support of the fork passage 12 acts against the weighting means and causes a pivotal movement of the flap 16 about its pivot axis 17 to a position in which the flap 16 releases access to the ballast. tunnel entrance 13.

Dans un second mode de réalisation de l'invention conforme aux figures 7 à 9, la liaison 5 pivot entre passage 12 de fourche et structure 2 support de charge est une liaison permanente non démontable.In a second embodiment of the invention according to Figures 7 to 9 the pivot connection between the fork passage 12 and the load support structure 2 is a non-removable permanent link.

Dans ce mode de réalisation, pour assurer la sécurité de l'ensemble et éviter tout désaccouplement intempestif du passage 12 de fourche de la fourche du chariot au cours du déplacement du passage 12 de fourche par ledit chariot, le dispositif est équipé de moyens 19 de liaison au chariot élévateur.In this embodiment, to ensure the safety of the assembly and to avoid inadvertent disconnection of the fork passage 12 of the fork of the carriage during the displacement of the fork passage 12 by said carriage, the device is equipped with means 19 of connection to the forklift.

Dans les exemples représentés, les moyens de liaison sont formés par un lien, tel qu'une chaîne, raccordé à une extrémité au passage 12 de fourche articulé et terminé à son autre extrémité par un crochet pour la fixation au chariot élévateur à fourche. Le passage 12 de fourche articulé à la structure 2 support est quant à lui formé de deux tunnels 13 maintenus parallèles entre eux, lesdits tunnels 13 étant, au niveau de l'une de leurs extrémités, reliés de manière articulée à la première surface 3 d'appui, en particulier au bord libre de ladite surface d'appui opposé à la zone de jonction desdites surfaces 3, 4 d'appui entre elles, par une liaison 5 pivot du genre charnière non démontable d'axe parallèle à la ligne de jonction desdites surfaces 3, 4 d'appui entre elles et orthogonal à l'axe longitudinal desdits tunnels.In the examples shown, the connecting means are formed by a link, such as a chain, connected at one end to the passage 12 articulated fork and terminated at its other end by a hook for attachment to the forklift. The articulated fork passage 12 to the support structure 2 is in turn formed of two tunnels 13 held parallel to one another, said tunnels 13 being, at one of their ends, hingedly connected to the first surface 3 d support, in particular at the free edge of said bearing surface opposite to the junction zone of said bearing surfaces 3, 4 between them, by a pivot connection 5 of the kind not releasable hinge axis parallel to the junction line said surfaces 3, 4 of support between them and orthogonal to the longitudinal axis of said tunnels.

Pour éviter tout endommagement de la charge au cours du passage de la structure 2 support d'une position à une autre, la structure 2 support comporte des moyens 6 de maintien de la charge 1 sur ladite structure 2 support. Dans l'exemple représenté en particulier aux figures 1 et 2, lesdits moyens 6 de maintien de la charge 1 sur ladite structure 2 support comprennent au moins un longeron ou montant coopérant avec le demi-cadre formé par les surfaces 3, 4 d'appui de la structure 2 support pour former un cadre ouvert à l'intérieur duquel la charge 1 est apte à être logée.To avoid damage to the load during the passage of the support structure 2 from one position to another, the support structure 2 comprises means 6 for maintaining the load 1 on said support structure 2. In the example shown in particular in figures 1 and 2 said load-holding means 1 on said support structure 2 comprise at least one spar or post cooperating with the half-frame formed by the supporting surfaces 3, 4 of the support structure 2 to form a frame open to the inside which the load 1 is able to be housed.

Le longeron des moyens 6 de maintien est équipé d'un patin s'étendant à l'intérieur du cadre ouvert, ce patin étant relié au longeron par une structure de type ciseau pour pouvoir être rapproché ou écarté du longeron et former un mors de serrage apte à coopérer avec la surface d'appui en regard de la structure de support pour constituer un étau apte à enserrer ladite charge 1.The spar of the holding means 6 is equipped with a pad extending inside the open frame, this shoe being connected to the spar by a scissor-type structure so that it can be moved closer to or away from the spar and form a clamping jaw. adapted to cooperate with the bearing surface opposite the support structure to form a vice capable of gripping said load 1.

Dans l'exemple représenté en particulier aux figures 7 et 8, qui constitue une variante des figures 1 et 2, lesdits moyens 6 de maintien de la charge 1 sur ladite structure 2 support comprennent au moins un longeron ou montant et une traverse articulés l'un à l'autre et coopérant avec le demi-cadre formé par les surfaces 3, 4 d'appui de la structure 2 support pour former un cadre ouvrable à l'intérieur duquel la charge 1 est apte à être logée.In the example shown in particular in figures 7 and 8 , which is a variant of figures 1 and 2 , said load-holding means 6 on said support structure 2 comprise at least one spar or upright and a cross member articulated to each other and cooperating with the half-frame formed by the support surfaces 3, 4 of the support structure 2 to form a workable frame within which the load 1 is adapted to be housed.

L'ouverture du cadre est disposée sensiblement au droit du passage 12 de fourche articulé lorsque la structure 2 support repose au sol à l'aide de la surface 3 d'appui articulée au passage 12 de fourche de manière à faciliter les opérations de mise en place de ladite charge sur la structure 2 support. Ainsi, lorsque la charge est stockée en palette, il suffit, à l'aide du chariot élévateur à fourche, après ouverture du cadre, de venir positionner la charge sur la surface 3 d'appui articulée au passage 12 de fourche avant de refermer le cadre. Pour permettre une retenue de la charge à l'intérieur du cadre, lorsque la charge n'occupe pas la totalité de l'espace disponible à l'intérieur du cadre, la traverse est équipée d'une butée de retenue de la charge 1 faisant saillie à l'intérieur du cadre, ladite butée 9 étant montée mobile le long de la traverse jusqu'à une position d'appui sur la charge 1 contenue dans le cadre et étant maintenue dans ladite position par la charge 1 assurant, par appui sur la saillie de la butée, l'immobilisation de la butée sur la traverse.The opening of the frame is disposed substantially to the right of the articulated fork passage 12 when the support structure 2 rests on the ground with the support surface 3 articulated to the fork passage 12 so as to facilitate the operations of setting place said load on the structure 2 support. Thus, when the load is stored in a pallet, it suffices, with the aid of the forklift, after opening the frame, to position the load on the bearing surface articulated to the fork passage 12 before closing the frame. To allow load retention inside the frame, when the load does not occupy all of the available space inside the frame, the cross is equipped with a load retaining stopper 1 projecting inside the frame, said stopper 9 being mounted movably along the the crossbar to a bearing position on the load 1 contained in the frame and being held in said position by the load 1 ensuring, by pressing the projection of the stop, immobilization of the stop on the cross.

Pour faciliter la manutention du dispositif, en particulier lorsque la structure 2 support repose au sol par sa deuxième surface 4 d'appui, c'est-à-dire celle exempte du passage 12 de fourche articulé, la structure 2 support est équipée d'un deuxième passage 9 de fourche disposé fixe par rapport aux surfaces 3, 4 d'appui de ladite structure 2 support.To facilitate the handling of the device, in particular when the support structure 2 rests on the ground by its second bearing surface 4, that is to say that free of the passage 12 articulated fork, the support structure 2 is equipped with a second passage 9 of fork arranged fixed relative to the surfaces 3, 4 of support of said support structure 2.

Dans les exemples représentés, ce deuxième passage 9 de fourche est formé de deux tunnels parallèles traversant ménagés dans l'épaisseur de la deuxième surface 4 d'appui de la structure 2 support. La première surface 3 d'appui est quant à elle simplement formée, comme mentionné ci-dessous, de deux longerons 7 constitués de profilés de section rectangulaire maintenus en disposition parallèle à l'aide de traverses 8 et se raccordant à l'une de leurs extrémités à un bord du plateau formant la deuxième surface 4 d'appui de la structure 2 support.In the examples shown, this second fork passage 9 is formed of two parallel parallel tunnels formed in the thickness of the second bearing surface 4 of the support structure 2. The first bearing surface 3 is itself simply formed, as mentioned below, of two longitudinal members 7 consisting of sections of rectangular section maintained in parallel arrangement by means of sleepers 8 and connected to one of their ends at an edge of the plate forming the second bearing surface 4 of the support structure 2.

Comme l'illustre en particulier la figure 2, la surface 4 d'appui de la structure 2 support exempte de passage 12 de fourche articulé, dite deuxième surface 4 d'appui de la structure support, repose au sol par un piétement formé de rails 11 d'appui au sol s'étendant sensiblement parallèlement au plan de ladite surface 4 d'appui. Ces rails 11 sont des rails télescopiques qui, en position sortie, s'étendent au-delà de l'emprise au sol de ladite deuxième surface 4 d'appui et forment une rampe de déchargement de la charge, lesdits rails 11 étant de préférence reliés à, ou au voisinage de, leur extrémité libre par une traverse cylindrique de type rouleau sur laquelle la charge 1 à décharger peut glisser. Cette conception de la surface 4 d'appui permet de simplifier encore les opérations de déchargement de la charge dans le cas par exemple de panneaux ou plaques stockés sur chant.As illustrated in particular by figure 2 , the support surface 4 of the support structure 2 without passage 12 articulated fork, said second support surface 4 of the support structure, rests on the ground by a base formed of rails 11 ground support extending substantially parallel to the plane of said bearing surface 4. These rails 11 are telescopic rails which, in the extended position, extend beyond the footprint of said second bearing surface 4 and form a loading unloading ramp, said rails 11 being preferably connected at or near their free end by a roll-type cross-member on which the load 1 to be unloaded can slide. This design of the support surface 4 makes it possible to simplify the unloading operations of the load in the case for example panels or plates stored on edge.

Dans le premier mode de réalisation de l'invention, le fonctionnement d'un tel dispositif de manutention de charge est le suivant. La structure 2 support repose en appui au sol par sa première surface 3 d'appui, comme l'illustre la figure 3, et le cadre est ouvert pour permettre l'introduction de la charge à l'intérieur du cadre.In the first embodiment of the invention, the operation of such a load handling device is as follows. The support structure 2 rests on the ground by its first bearing surface 3, as illustrated by FIG. figure 3 , and the frame is open to allow the introduction of the load inside the frame.

Le patin constituant un mors de serrage est ensuite rapproché de la charge 1 pour l'enserrer. Les dents de la fourche 20 du chariot élévateur sont introduites dans les tunnels du passage 12 de fourche articulé. Le passage 12 de fourche est couplé par ses crochets 15 à la traverse 8 de la première surface 3 d'appui de la structure 2 support. Le passage 12 de fourche est entraîné en déplacement vers le haut par le chariot à fourche et provoque en parallèle le déplacement à pivotement de la structure 2 support qui pivote autour de son point d'appui au sol formé par le sommet de l'angle entre lesdites surfaces 3, 4 d'appui pour passer d'une position dans laquelle la structure 2 support repose en appui au sol par sa première surface 3 d'appui à une position dans laquelle elle repose en appui au sol par sa deuxième surface 4 d'appui. Lors de ce déplacement vers le haut du passage 12 de fourche, les moyens de retenue passent d'une position inactive à une position active. En position haute, c'est-à-dire écartée du sol, le passage 12 de fourche est désaccouplé de la structure 2 support par séparation des moyens de liaison équipant le passage 12 de fourche des moyens de liaison équipant la structure 2 support ou, en d'autres termes, par désaccouplage des crochets 15 du passage 12 de fourche de la traverse 8 de la structure 2 support. Le passage 12 de fourche est reposé en position d'appui au sol, les moyens de retenue reviennent en position inactive et la fourche du chariot à fourche peut être sortie des tunnels du passage 12 de fourche. Les opérations inverses sont à effectuer pour le basculement inverse de la structure 2 support. Lorsque la structure 2 support est amenée dans la position basculée souhaitée, le déchargement de la charge peut s'opérer à l'aide des rails 11 amenés en position déployée. La présence d'au moins un passage de fourche fixe directement intégré à la structure 2 support permet en outre de manipuler la structure 2 support directement à l'aide du chariot élévateur à fourche sans utiliser le passage 12 de fourche.The shoe forming a clamping jaw is then brought closer to the load 1 to grip it. The teeth of fork 20 of the forklift are introduced into the tunnels of passage 12 articulated fork. The passage 12 of the fork is coupled by its hooks 15 to the cross member 8 of the first bearing surface 3 of the support structure 2. The fork passage 12 is driven upwards by the forklift and causes in parallel the pivotal movement of the support structure 2 which pivots about its bearing point to the ground formed by the vertex of the angle between said support surfaces 3, 4 to move from a position in which the support structure 2 rests against the ground by its first bearing surface 3 at a position in which it rests in support of the ground by its second surface 4 d 'support. During this upward movement of the fork passage 12, the retaining means pass from an inactive position to an active position. In the upper position, that is to say away from the ground, the fork passage 12 is uncoupled from the support structure 2 by separation of the connecting means equipping the fork passage 12 of the connecting means equipping the support structure 2 or, in other words, by uncoupling the hooks 15 of the fork passage 12 of the cross member 8 of the support structure 2. The passage 12 of the fork is rested in the ground support position, the retaining means return to the inactive position and the fork of the forklift may be output from the tunnels of the passage 12 fork. Inverse operations are to be performed for the reverse tilting of the support structure 2. When the support structure 2 is brought into the desired tilted position, the unloading of the load can operate with the rails 11 brought into the deployed position. The presence of at least one fixed fork passage directly integrated in the support structure 2 further makes it possible to manipulate the support structure 2 directly using the forklift truck without using the fork passage 12.

Dans le deuxième mode de réalisation de l'invention, le fonctionnement d'un tel dispositif de manutention de charge est le suivant. La structure 2 support repose en appui au sol par sa première surface 3 d'appui, comme l'illustre la figure 7, et le cadre est ouvert pour permettre l'introduction de la charge à l'intérieur du cadre. Le cadre est ensuite refermé et le lien est accroché par son crochet au chariot élévateur après que les dents de fourche du chariot élévateur aient été introduites dans les tunnels du passage 12 de fourche articulé. Le passage 12 de fourche est entraîné en déplacement vers le haut par le chariot à fourche et provoque en parallèle le déplacement à pivotement de la structure 2 support qui pivote autour de son point d'appui au sol formé par le sommet de l'angle entre lesdites surfaces 3, 4 d'appui pour passer d'une position dans laquelle la structure 2 support repose en appui au sol par sa première surface 3 d'appui à une position dans laquelle elle repose en appui au sol par sa deuxième surface 4 d'appui. Une fois ce basculement opéré, le lien est détaché du chariot élévateur et la fourche du chariot est extraite du passage 12 de fourche. Le cadre peut être ouvert pour permettre le déchargement de la charge à l'aide des rails 11 amenés en position déployée. Bien évidemment, un déplacement à pivotement suivant une direction inverse de la structure 2 support est obtenu par abaissement du passage 12 de fourche à partir de la position représentée en 9C.In the second embodiment of the invention, the operation of such a load handling device is as follows. The support structure 2 rests on the ground by its first bearing surface 3, as illustrated by FIG. figure 7 , and the frame is open to allow the introduction of the load inside the frame. The frame is then closed and the link is hooked by the hook to the forklift after the forklift fork teeth have been introduced into the tunnels of the passage 12 articulated fork. The fork passage 12 is driven upwards by the forklift and causes in parallel the pivotal movement of the support structure 2 which pivots about its bearing point to the ground formed by the vertex of the angle between said support surfaces 3, 4 to move from a position in which the support structure 2 rests against the ground by its first bearing surface 3 at a position in which it rests in support of the ground by its second surface 4 d 'support. Once this changeover has been made, the link is detached from the forklift and the fork of the carriage is extracted from the passage 12 of the fork. The frame can be opened to allow the unloading of the load with the rails 11 brought into the deployed position. Of course, a pivotal displacement in a reverse direction of the support structure 2 is obtained by lowering the fork passage 12 from the position shown at 9C.
