Description

"Cadre de manutention pliant, pour charges diverses"
La présente invention concerne un cadre de manutention pliant, pour charges diverses à transporter, qui est destiné plus particulièrement, quoique non exclusivement, au transport d'objets allongés, tels que tubes ou pièces de bois, groupés en bottes."Folding handling frame, for various loads"
The present invention relates to a folding handling frame, for various loads to be transported, which is intended more particularly, although not exclusively, for the transport of elongated objects, such as tubes or pieces of wood, grouped in bundles.

Le transport de ce genre d'objets, et aussi d'autres produits industriels, s'effectue de façon habituelle dans des cadres, des berceaux ou des conteneurs, de dimensions appropriées.La plupart des cadres ou autres, actuellement existants, sont des structures rigides qui possédent un encombrement inutilement important, lorsque ces cadres ou autres ne contiennent aucune charge. Il en résulte que le transport à vide et le stockage de ces cadres sont coûteux, et diminuent la rentabilité de leur utilisation. En particulier, les frais de transport sont élevés pour ramener les cadres vides à leur point de départ, après livraison de leur charge ; quant au stockage, celui-ci nécessite des surfaces d'entrepôts importantes. The transport of this kind of objects, and also of other industrial products, is carried out in a usual way in frames, cradles or containers, of appropriate dimensions. Most of the frames or others, currently existing, are structures rigid which has an unnecessarily large size, when these frames or others contain no load. As a result, empty transport and storage of these frames are expensive, and reduce the profitability of their use. In particular, the transport costs are high to bring the empty frames back to their starting point, after delivery of their load; as for storage, this requires significant warehouse space.

On connaît, par ailleurs, des conteneurs notamment du type grillagé, partiellement ou totalement démontables, ce qui permet d'obtenir un gain de place pour le transport à vide et le stockage. Toutefois, ces conteneurs possèdent une structure peu résistante sur le plan mécanique et facilement déformable, et leur démontage entraîne un risque de dispersion et de perte de leurs éléments constitutifs. Containers are also known, in particular of the mesh type, which are partially or completely removable, which saves space for empty transport and storage. However, these containers have a structure that is not very mechanically resistant and easily deformable, and their dismantling involves a risk of dispersion and loss of their constituent elements.

La présente invention vise à éliminer ces inconvénients, en fournissant un cadre de manutention repliable sous un faible volume, sans démontage, qui résoud tous les problèmes de retour et de stockage à vide actuellement rencontrés. The present invention aims to eliminate these drawbacks, by providing a collapsible handling frame in a small volume, without disassembly, which solves all the problems of return and vacuum storage currently encountered.

A cet effet, le cadre de manutention pliant pour charges diverses, objet de l'invention, comprend essentiellement deux berceaux parallèles en forme de "U", chacun avec deux montants et une partie inférieure reliant ces montants, les deux berceaux étant reliés entre eux de façon articulée par au moins deux traverses parallèles, de manière à constituer, vu en plan par dessus, une structure en parallélogramme déformable. To this end, the folding handling frame for various loads, object of the invention, essentially comprises two parallel cradles in the shape of a "U", each with two uprights and a lower part connecting these uprights, the two cradles being interconnected articulated by at least two parallel crosspieces, so as to constitute, seen in plan from above, a deformable parallelogram structure.

Le cadre objet de l'invention peut ainsi être mis soit dans une position déployée d'utilisation, avec les deux berceaux placés en vis-à-vis et écartés l'un de l'autre, pour supporter et maintenir une charge, soit dans une position repliée avec les deux berceaux ramenés pratiquement dans un même plan, ce qui permet un transport à vide et un stockage sous un faible encombrement. La structure de ce cadre de manutention, réalisable en tubes métalliques, est simple, relativement légère et toutefois résistante. Les opérations de déploiement et de repliage sont réalisables facilement et rapidement, par une seule personne. The frame object of the invention can thus be put either in a deployed position of use, with the two cradles placed opposite and spaced from each other, to support and maintain a load, or in a folded position with the two cradles brought almost in the same plane, which allows empty transport and storage in a small footprint. The structure of this handling frame, made of metal tubes, is simple, relatively light and yet resistant. The deployment and folding operations can be carried out easily and quickly, by a single person.

De préférence, les deux traverses du cadre sont liées, de façon articulée, aux parties inférieures des deux berceaux, ce qui laisse dégagée toute la partie recevant la charge. Dans une forme particulière de réalisation de ce cadre, chaque berceau possède à sa partie inférieure deux pieds-supports verticaux, espacés l'un par rapport à l'autre, et chaque traverse comporte, à ses extrémités, deux manchons- d'axe vertical qui entourent des pieds-supports appartenant respectivement aux deux berceaux, avec possibilité de rotation de chaque manchon relativement au.pied-support correspondant. Les pieds-supports, servant à l'appui au sol du cadre, sont ainsi mis à profit pour la réalisation de l'articulation des traverses. Preferably, the two cross members of the frame are linked, in an articulated manner, to the lower parts of the two cradles, which leaves the entire part receiving the load free. In a particular embodiment of this frame, each cradle has at its lower part two vertical support legs, spaced apart from one another, and each cross member comprises, at its ends, two sleeves- of vertical axis which surround support legs belonging respectively to the two cradles, with the possibility of rotation of each sleeve relative to the corresponding support leg. The support feet, used to support the frame on the ground, are thus used to achieve the articulation of the crosspieces.

Le cadre de manutention repliable, objet de l'invention, peut comporter à titre complémentaire des moyens de verrouillage pour son maintien en position déployée d'utilisation. Dans un mode de réalisation particulier, ces moyens de verrouillage comprennent, d'une part, une clavette ou goupille fixée sur un pied-support et, d'autre part, une encoche correspondante ménagée dans le manchon solidaire d'une traverse et entourant le pied-support considéré, le manchon étant monté autour de ce pied-support avec un jeu vertical. Le jeu permet d'emboîter l'encoche sur la clavette ou goupille, pour empêcher le pivotement du manchon donc de la traverse, ou de soulever le manchon en dégageant l'encoche, ce qui autorise le pivotement de la traverse, donc le repliage du cadre. The folding handling frame, object of the invention, may additionally include locking means for keeping it in the deployed position of use. In a particular embodiment, these locking means comprise, on the one hand, a key or pin fixed on a support leg and, on the other hand, a corresponding notch formed in the sleeve integral with a cross member and surrounding the support leg considered, the sleeve being mounted around this support leg with a vertical clearance. The game allows to fit the notch on the key or pin, to prevent pivoting of the sleeve therefore of the cross member, or to lift the sleeve by releasing the notch, which allows the pivoting of the cross member, therefore the folding of the frame.

De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce cadre de manutention pliant, pour charges diverses

Comme le montre le dessin, le cadre de manutention comprend deux berceaux identiques et parallèles 1 et 2, chacun en forme de "U" avec deux montants verticaux 3 et 4 reliés rigidement à leur base par une partie horizontale 5. Les deux berceaux I et 2 sont reliés entre eux, de façon articulée, par deux traverses inférieures horizontales et parallèles 6 et 7 de même longueur, de manière à constituer une structure en parallélogramme déformable, si on considère le cadre vu en plan par dessus (selon figures 2 et 5). As shown in the drawing, the handling frame comprises two identical and parallel cradles 1 and 2, each in the shape of a "U" with two vertical uprights 3 and 4 rigidly connected to their base by a horizontal part 5. The two cradles I and 2 are interconnected, in an articulated manner, by two horizontal and parallel lower crosspieces 6 and 7 of the same length, so as to constitute a deformable parallelogram structure, if we consider the frame seen in plan from above (according to Figures 2 and 5 ).

Les deux berceaux 1 et 2 et les deux traverses 6 et 7 sont réalisés en tubes métalliques, droits ou coudés. Sous la partie horizontale 5 de chaque berceau 1 ou 2 font saillie deux pieds-supports verticaux 8, également tubulaires, espacés l'un par rapport à l'autre et se terminant par des rondelles d'appui 9. Chaque traverse 6 ou 7 comporte, à ses extrémités, deux manchons verticaux 10 qui- entourent des pieds-supports 8 appartenant respectivement aux deux berceaux I et 2, avec possibilité de rotation, ce qui réalise la liaison articulée entre les berceaux 1 et 2, d'une part, et les traverses 6 et 7, d'autre part. The two cradles 1 and 2 and the two crosspieces 6 and 7 are made of metal tubes, straight or bent. Under the horizontal part 5 of each cradle 1 or 2 protrude two vertical support legs 8, also tubular, spaced apart from one another and ending with support washers 9. Each crosspiece 6 or 7 comprises , at its ends, two vertical sleeves 10 which surround support legs 8 belonging respectively to the two cradles I and 2, with the possibility of rotation, which achieves the articulated connection between the cradles 1 and 2, on the one hand, and sleepers 6 and 7, on the other hand.

Aux sommets des montants 3 et 4 des berceaux I et 2 sont montés des anneaux de suspension 11, fixes ou pivotants. Ces anneaux supérieurs 11 peuvent être reliés entre eux par des chaînes, non représentées. At the tops of the uprights 3 and 4 of the cradles I and 2 are mounted suspension rings 11, fixed or pivoting. These upper rings 11 can be connected together by chains, not shown.

En position déployée d'utilisation (figures I à 4), les deux berceaux 1 et 2 sont situés en vis-à-vis, dans des plans verticaux parallèles, et les deux traverses 6 et 7 s'étendent perpendiculairement à ces plans verticaux. In the deployed position of use (Figures I to 4), the two cradles 1 and 2 are located opposite, in parallel vertical planes, and the two crosspieces 6 and 7 extend perpendicular to these vertical planes.

Le cadre peut ainsi recevoir une charge, indiquée très schématiquement en 12 sur la figure 1, la charge 12 reposant sur les parties horizontales 5 des deux berceaux I et 2, et étant retenue latéralement par les montants 3 et 4 de ces berceaux.The frame can thus receive a load, indicated very diagrammatically at 12 in FIG. 1, the load 12 resting on the horizontal parts 5 of the two cradles I and 2, and being retained laterally by the uprights 3 and 4 of these cradles.

Dans le cas d'une charge 12 constituée par une botte d'objets allongés, tels que tubes ou pièces de bois, ces objets sont disposés parallèlement aux traverses 6 et 7, et les berceaux I et 2 suffisent en principe pour assurer leur maintien. Pour d'autres objets, il peut être utile de placer une plaque de fond, non représentée, sur les parties horizontales 5 des berceaux 1 et 2, cette plaque pouvant comporter des encoches qui la positionnent exactement par rapport aux montants 3 et 4. Par ailleurs, dans le cas d'une charge lourde, la déformation du cadre peut être évitée par les chaines mentionnées plus haut, reliant les anneaux supérieurs 11. In the case of a load 12 consisting of a bunch of elongated objects, such as tubes or pieces of wood, these objects are arranged parallel to the crosspieces 6 and 7, and the cradles I and 2 are sufficient in principle to ensure their maintenance. For other objects, it may be useful to place a bottom plate, not shown, on the horizontal parts 5 of the cradles 1 and 2, this plate possibly having notches which position it exactly with respect to the uprights 3 and 4. By moreover, in the case of a heavy load, the deformation of the frame can be avoided by the chains mentioned above, connecting the upper rings 11.

Le cadre, portant sa charge 12, est déplaçable au moyen d'appareils de manutention habituels, tels que chariot élévateur à fourche et transpalette. Grâce à ses anneaux de suspension 11, il est également préhensible au moyen d'un engin de levage, tel que grue ou pont roulant, muni d'un palonnier à quatre élingues. The frame, carrying its load 12, is movable by means of usual handling devices, such as forklift and pallet truck. Thanks to its suspension rings 11, it can also be grasped by means of a lifting machine, such as a crane or overhead crane, provided with a lifting beam with four slings.

Lorsque le cadre n'est pas utilisé, il peut être facilement replié comme le montre la figure 5, grâce à sa structure en parallélogramme déformable. Les deux berceaux 1 et 2 et les deux traverses 6 et 7 sont alors ramenés pratiquement dans un même plan, ce qui permet le transport à vide et le stockage de ce cadre sous un encombrement minimal. Le volume du cadre replié représente, par exemple, entre 1/5 et 1/6 du volume de ce cadre en position déployée d'utilisation. When the frame is not in use, it can be easily folded as shown in Figure 5, thanks to its deformable parallelogram structure. The two cradles 1 and 2 and the two crosspieces 6 and 7 are then brought back practically in the same plane, which allows the empty transport and the storage of this frame in a minimal space requirement. The volume of the folded frame represents, for example, between 1/5 and 1/6 of the volume of this frame in the deployed position of use.

Comme le montre plus particulièrement la figure 6, des moyens peuvent être ajoutés, sur l'un des pieds-supports 8, pour assurer un verrouillage du cadre dans la position déployée d'utilisation. Ce pied-support 8 comporte une clavette ou une goupille fixe 13, faisant saillie latéralement. As shown more particularly in Figure 6, means can be added, on one of the support legs 8, to ensure locking of the frame in the deployed position of use. This support foot 8 comprises a key or a fixed pin 13, projecting laterally.

Le manchon 10, solidaire de la traverse 6, est mobile verticalement sur une certaine course par rapport au pied 8, comme indiqué par une flèche double 14, et ce manchon présente sur son bord inférieur une encoche 15. En positiori déployée, l'encoche 15 coincide avec la clavette ou goupille 13, et sous l'effet du poids de la traverse 6, auquel peut s'ajouter le poids de la charge, le manchon 10 est abaissé et la clavette ou goupille 13 s'introduit dans l'encoche 15, empêchant ainsi tout pivotement de la traverse 6 relativement au pied 8 donc au berceau. A l'inverse, pour replier le cadre, on soulève légèrement le manchon 10 pour dégager la clavette ou goupille 13 de l'encoche 15, ce qui permet de faire pivoter librement la traverse 6.The sleeve 10, integral with the cross-member 6, is movable vertically over a certain stroke relative to the foot 8, as indicated by a double arrow 14, and this sleeve has on its lower edge a notch 15. In the deployed position, the notch 15 coincides with the key or pin 13, and under the effect of the weight of the cross-member 6, to which the weight of the load can be added, the sleeve 10 is lowered and the key or pin 13 is introduced into the notch 15, thus preventing any pivoting of the crosspiece 6 relative to the foot 8 therefore to the cradle. Conversely, to fold the frame, the sleeve 10 is slightly raised to release the key or pin 13 from the notch 15, which allows the cross-member 6 to pivot freely.

On comprend qu'en raison de la structure en parallélogramme déformable, le verrouillage réalisé comme décrit ci-dessus sur un seul pied-support 8 rigidifie l'ensemble du cadre, dans sa position déployée d'utilisation, sans qu'il soit nécessaire de prévoir des moyens de verrouillage analogues surales trois autres pieds-supports 8. De plus, ces moyens de verrouillage restent facultatifs, un maintien correct en position déployée pouvant être déjà assuré par la charge 12 elle-même, dans de nombreux cas d'utilisation. It is understood that due to the deformable parallelogram structure, the locking produced as described above on a single support leg 8 stiffens the entire frame, in its deployed position of use, without the need to provide similar locking means on three other support legs 8. In addition, these locking means are optional, correct maintenance in the deployed position can already be provided by the load 12 itself, in many cases of use.

Comme il va de soi, et comme il ressort de ce qui précède,
I'invention ne se limite pas à la seule forme d'exécution de ce cadre de manutention pliant qui a été décrite ci-dessus, à titre d'exemple.
