Description

La présente invention concerne une caisse métallique repliable, notamment de transport d'un matériau sensible au fluage, par exemple du caoutchouc synthétique conditionné en balles, ainsi qu'un procédé de remplissage de la caisse et un procédé de transfert de marchandises contenues dans une telle caisse vers une caisse en bois.The present invention relates to a collapsible metal container, in particular for transporting a material sensitive to creep, for example synthetic rubber packaged in bales, as well as a method of filling the box and a method of transferring goods contained in such crate towards a wooden crate.

Elle a pour object une caisse selon le preamble de la revendication 1. Une telle caisse est décrit dans le document US-4735330 .Its object is a box according to the preamble of claim 1. Such a box is described in document US 4735330 .

On connaît des caisses repliables en aluminium comportant une partie de base de forme générale rectangulaire, reposant sur quatre pieds, et des panneaux amovibles articulés sur cette partie de base.Folding aluminum crates are known having a base portion of generally rectangular shape, resting on four feet, and removable panels hinged to this base portion.

Les deux grands panneaux comportent, sur toute leur longueur en partie inférieure, un profilé extrudé agencé pour s'emboîter, lorsque la caisse est montée, dans un profilé extrudé correspondant de la partie de base. Les grands panneaux peuvent être enlevés dès qu'on les rabat vers l'intérieur ou vers l'extérieur de la caisse.The two large panels have, throughout their length in the lower part, an extruded profile arranged to fit, when the body is mounted, in a corresponding extruded profile of the base portion. Large panels can be removed as soon as they are folded in or out of the box.

Les petits panneaux de ces caisses en aluminium sont reliés à la partie de base à l'aide de goupilles engagées dans des orifices circulaires des montants d'angle verticaux de la partie de base. Pour démonter les petits panneaux, il faut, à l'aide d'outils adaptés, retirer les goupilles et une telle opération de démontage est réservée essentiellement à la réparation de la caisse.The small panels of these aluminum boxes are connected to the base part by means of pins engaged in circular orifices of the vertical corner posts of the base part. To dismantle the small panels, it is necessary, with the aid of adapted tools, to remove the pins and such disassembly operation is reserved essentially for the repair of the body.

On connaît par ailleurs des caisses repliables en acier comportant également une partie de base de forme générale rectangulaire, reposant sur quatre pieds, et des panneaux articulés sur cette partie de base. Les pieds sont saillants de manière à coiffer une caisse sous-jacente lorsque deux caisses sont gerbées, et verrouiller ainsi les panneaux de la caisse sous-jacente. Les quatre panneaux sont démontables mais le sont relativement difficilement, étant reliés à la partie de base à l'aide de goupilles, ce qui présente les inconvénients précités.Also known collapsible steel crates also having a base portion of generally rectangular shape, resting on four feet, and panels articulated on this base portion. The legs are protruding so as to cap an underlying crate when two crates are stacked, and thus lock the panels of the underlying crate. The four panels are removable but are relatively difficult, being connected to the base portion with the help of pins, which has the aforementioned drawbacks.

Ces caisses connues comportent en outre, sur chacun des côtés de la partie de base, une pluralité de taquets de retenue contre lesquels les panneaux peuvent venir en appui, notamment lorsque la pression de la marchandise à l'intérieur de la caisse est importante, ce qui est le cas quand celle-ci est constituée de balles de caoutchouc synthétique. Les traverses inférieures des quatre panneaux comportent chacune un profilé de section sensiblement circulaire, ouvert partiellement vers l'extérieur, de manière à ménager un espace dans lequel les taquets peuvent s'engager lorsque l'on rabat les panneaux vers l'extérieur de la caisse.These known boxes further comprise, on each of the sides of the base part, a plurality of retaining cleats against which the panels can come into abutment, particularly when the pressure of the goods inside the box is large, which is the case when it consists of synthetic rubber bullets. The lower crosspieces of the four panels each comprise a section of substantially circular section, partially open towards the outside, so as to provide a space in which the tabs can engage when the panels are folded outwardly of the body .

Il existe un besoin pour bénéficier d'une caisse métallique repliable perfectionnée et relativement peu coûteuse, dont le gerbage soit facile à effectuer.There is a need to benefit from an improved and relatively inexpensive foldable metal crate, which stacking is easy to perform.

Il existe aussi un besoin pour bénéficier d'une caisse métallique repliable permettant d'utiliser au mieux l'espace disponible dans les conteneurs maritimes.There is also a need to benefit from a collapsible metal case to make the best use of available space in sea containers.

Il existe également un besoin pour bénéficier d'une caisse métallique repliable permettant un démontage simple et rapide des panneaux lors de l'utilisation de la caisse.There is also a need to benefit from a collapsible metal case for simple and quick disassembly of the panels when using the body.

Il existe encore un besoin pour bénéficier d'une caisse métallique repliable à usage multiple, et pour permettre d'utiliser au mieux le volume intérieur d'une caisse métallique repliable lors de son chargement.There is still a need to benefit from a collapsible metallic case for multiple use, and to allow the best use of the interior volume of a collapsible metal case when it is loaded.

L'invention vise à répondre à tout ou partie des besoins précités.The invention aims to meet all or part of the aforementioned needs.

La caisse métallique repliable selon l'invention comporte une partie de base de forme générale rectangulaire comportant quatre montants d'angle verticaux, et quatre panneaux articulés sur la partie de base, dont deux petits panneaux et deux grands panneaux, chaque panneau comportant deux montants latéraux verticaux, au moins l'un des panneaux étant amovible, et de préférence tous les panneaux l'étant.The collapsible metal box according to the invention comprises a base portion of generally rectangular shape comprising four vertical uprights, and four panels articulated on the base part, including two small panels and two large panels, each panel having two lateral uprights vertical, at least one of the panels being removable, and preferably all the panels being.

Selon un aspect de l'invention, au moins un montant latéral et de préférence chacun de ceux-ci comporte un premier élément d'articulation mâle engagé dans une ouverture correspondante du montant d'angle correspondant. En variante, au moins un montant d'angle, et de préférence chaque montant d'angle, comporte un premier élément d'articulation mâle et le montant latéral correspondant l'ouverture associée.According to one aspect of the invention, at least one lateral upright and preferably each of them comprises a first male hinge member engaged in a corresponding opening of the corresponding corner upright. In a variant, at least one corner post, and preferably each corner post, comprises a first male articulation element and the lateral post corresponding to the associated opening.

La caisse peut se caractériser par le fait que l'ouverture précitée présente une forme permettant de désolidariser le panneau concerné de la partie de base, par un déplacement relatif au moins sensiblement verticalement entre le montant latéral et le montant d'angle.The box may be characterized in that the aforementioned opening has a shape for separating the relevant panel from the base portion, by a relative movement at least substantially vertically between the lateral upright and the corner post.

L'invention rend possible de monter et de démonter facilement, notamment sans outil spécifique, les différents panneaux de la caisse lors de l'utilisation de celle-ci, ce qui peut être avantageux notamment pour le chargement et le déchargement des marchandises, par exemple.The invention makes it possible to easily assemble and disassemble, especially without specific tools, the various panels of the box during use thereof, which can be advantageous especially for the loading and unloading of goods, for example .

Dans toute la suite, les termes « vertical/horizontal, supérieur/inférieur, haut/bas, dessus/dessous, extérieure/intérieure » et autres termes d'orientation doivent être compris relativement à un observateur se trouvant devant la caisse posée à l'endroit sur une surface plane horizontale.Throughout, the terms "vertical / horizontal, upper / lower, top / bottom, top / bottom, outer / inner" and other terms of reference must be read in relation to an observer in front of the cashier place on a flat horizontal surface.

Par « caisse repliable », on entend une caisse dont on peut rabattre les panneaux vers l'intérieur ou vers l'extérieur de la caisse.By "collapsible crate" is meant a crate which can be folded panels inward or outward of the crate.

L'articulation des panneaux sur la partie de base peut s'effectuer de multiples manières, la ou les ouvertures précitées qui reçoivent le ou les éléments d'articulation mâles correspondants et permettent de désolidariser les panneaux de la partie de base pouvant être réalisées sur les montants d'angle de la partie de base, ou en variante sur les panneaux eux-mêmes.The articulation of the panels on the base part can be effected in multiple ways, the aforementioned opening (s) which receive the corresponding male articulation element (s) and make it possible to separate the panels of the base part which can be made on the corner uprights of the base part, or alternatively on the panels themselves.

Dans un exemple de mise en oeuvre, une ouverture au moins peut être constituée par une fente verticale débouchant à l'extrémité supérieure d'un montant d'angle, cette fente pouvant notamment être réalisée sur un côté du montant d'angle qui fait face à un grand panneau. Au moins une ouverture peut encore être constituée par une fente verticale débouchant à l'extrémité inférieure d'un montant latéral d'un panneau.In an exemplary embodiment, at least one opening may be constituted by a vertical slot opening at the upper end of a corner post, this slot being able to be made in particular on one side of the corner post which faces to a large panel. At least one opening may also be constituted by a vertical slot opening at the lower end of a side jamb of a panel.

Toujours dans un exemple de mise en oeuvre, au moins une ouverture peut déboucher sur un côté d'un montant d'angle qui est adjacent au côté qui fait face à l'élément d'articulation. Cela peut être le cas par exemple lorsque l'ouverture est destinée à accueillir l'élément d'articulation d'un petit panneau. En variante, au moins une ouverture peut déboucher sur un côté du montant latéral du panneau qui est adjacent au côté qui fait face au premier élément d'articulation, celui-ci étant porté par un montant d'angle de la partie de base.Still in an exemplary implementation, at least one opening may lead to one side of an angle post that is adjacent to the side facing the hinge member. This may be the case for example when the opening is intended to accommodate the hinge element of a small panel. Alternatively, at least one opening may open onto one side of the side jamb of the panel which is adjacent to the side facing the first hinge member, the latter being carried by a corner post of the base portion.

Lorsque le premier élément d'articulation est sur un panneau, ce dernier peut comporter un deuxième élément d'articulation mâle situé à l'opposé du premier élément d'articulation et engagé dans une ouverture, de préférence sensiblement circulaire, du montant d'angle correspondant.When the first hinge member is on a panel, the latter may comprise a second male hinge element located opposite the first hinge member and engaged in an opening, preferably substantially circular, of the corner post corresponding.

En variante, mais toujours dans le cas où le premier élément d'articulation est sur le panneau, ce dernier peut comporter, à l'opposé du premier élément d'articulation, une ouverture, de préférence circulaire, et le montant d'angle correspondant peut comporter un deuxième élément d'articulation mâle engagé dans cette ouverture.Alternatively, but always in the case where the first hinge member is on the panel, the latter may comprise, opposite the first hinge member, an opening, preferably circular, and the corresponding angle post may comprise a second male hinge element engaged in this opening.

Lorsque le premier élément d'articulation mâle est réalisé sur le montant d'angle, le panneau peut comporter un deuxième élément d'articulation mâle engagé dans une ouverture associée, de préférence circulaire, d'un montant d'angle correspondant. En variante, mais toujours dans le cas où le premier élément d'articulation mâle est réalisé sur le montant d'angle, le panneau amovible peut comporter, à l'opposé du premier élément d'articulation, une ouverture circulaire, et le montant d'angle correspondant peut comporter un deuxième élément d'articulation mâle, engagé dans l'ouverture circulaire.When the first male hinge member is formed on the corner post, the panel may comprise a second male hinge member engaged in an associated, preferably circular, aperture of a corresponding corner post. Alternatively, but still in the case where the first male hinge member is formed on the corner post, the removable panel may comprise, opposite the first element articulation, a circular opening, and the corresponding corner post may comprise a second male joint member, engaged in the circular opening.

La caisse peut être réalisée en acier, en partie au moins.The box can be made of steel, at least in part.

La partie de base peut comporter, sur au moins un côté entre deux montants d'angle, au moins un taquet de retenue d'un panneau correspondant.The base portion may comprise, on at least one side between two corner posts, at least one retaining latch of a corresponding panel.

Ce dernier peut comporter une traverse inférieure comprenant un premier profilé, ouvert vers le bas, et au moins une ouverture sur l'aile extérieure du profilé pour recevoir le taquet lorsque le panneau est rabattu vers l'extérieur.The latter may comprise a lower cross member comprising a first section, open downwards, and at least one opening on the outer flange of the section to receive the cleat when the panel is folded outwardly.

La traverse inférieure d'un panneau, notamment d'un petit panneau, peut comporter un axe, notamment un axe plein, s'étendant au moins partiellement entre les ailes du premier profilé, par exemple sur toute la largeur du panneau. Cet axe peut ménager avec l'âme du profilé un espace suffisant pour permettre au taquet de s'y engager.The bottom rail of a panel, in particular a small panel, may comprise an axis, in particular a solid axis, extending at least partially between the flanges of the first profile, for example over the entire width of the panel. This axis can fit with the soul of the profile sufficient space to allow the cleat to engage.

La traverse inférieure d'un panneau, notamment d'un petit panneau, peut comporter en outre un deuxième profilé de renfort, superposé au premier.The bottom rail of a panel, including a small panel, may further comprise a second reinforcing section, superimposed on the first.

Dans le cas où un panneau, notamment un petit panneau, comporte le premier élément d'articulation mâle, celui-ci peut être constitué par une extrémité de l'axe précité.In the case where a panel, in particular a small panel, comprises the first male articulation element, it may consist of an end of the aforementioned axis.

L'épaisseur maximale des petits panneaux peut être inférieure à celle des grands panneaux. Les petits panneaux peuvent avoir, par exemple, une épaisseur maximale de 20 mm environ, et les grands panneaux une épaisseur maximale de 30 mm environ.The maximum thickness of the small panels may be smaller than that of the large panels. The small panels may have, for example, a maximum thickness of about 20 mm, and large panels a maximum thickness of about 30 mm.

La partie de base repose de préférence sur au moins quatre pieds qui peuvent comporter chacun un socle inférieur, l'extrémité inférieure de chaque montant d'angle de la partie de base se situant au-dessus du socle du pied correspondant.The base portion preferably rests on at least four legs which may each have a lower base, the lower end of each corner post of the base portion being above the base of the corresponding foot.

Les grands panneaux peuvent comporter, en partie supérieure, des pions et au moins un montant d'angle de la partie de base peut comporter en partie inférieure au moins une ouverture de réception d'un pion. Cette ouverture peut également être agencée de manière à recevoir le montant d'angle d'une caisse sous-jacente lorsque deux caisses sont gerbées à l'état replié.The large panels may comprise, in the upper part, pins and at least one corner upright of the base portion may comprise in the lower part at least one receiving opening of a pin. This opening can also be arranged to receive the corner post of an underlying crate when two crates are stacked in the folded state.

L'ouverture de réception d'un pion peut être formée vers le bas et en partie au moins latéralement vers l'intérieur.The receiving aperture of a pin may be formed downward and partly at least laterally inwardly.

Au moins un pion peut présenter une forme générale effilée vers le haut, notamment semi-pyramidale.At least one peg may have a generally tapered upward shape, in particular semi-pyramidal shape.

La caisse peut comporter au moins un système de verrouillage d'au moins un panneau articulé avec un panneau adjacent.The box may include at least one locking system of at least one hinged panel with an adjacent panel.

L'invention a encore pour objet, selon un autre de ses aspects, un procédé de transport de balles de caoutchouc synthétique, pouvant se caractériser par le fait que l'on utilise une caisse telle que définie plus haut.The invention further relates, in another of its aspects, a method of transporting synthetic rubber bales, which can be characterized by the fact that we use a box as defined above.

L'invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un procédé de remplissage d'une caisse métallique comportant des panneaux, avec des balles d'un matériau sensible au fluage, notamment des balles de caoutchouc synthétique, ce procédé pouvant comporter l'étape consistant à remplir la caisse en constituant un empilement de balles dont la dernière couche dépasse du bord supérieur des panneaux tout en étant suffisamment engagée dans la caisse pour qu'au cours du fluage, cette dernière couche se loge d'elle-même sensiblement dans le volume intérieur de la caisse.The invention also relates, independently or in combination with the foregoing, to a method of filling a metal crate comprising panels, with balls of a material sensitive to creep, in particular synthetic rubber balls, this method which may comprise the step of filling the body by constituting a stack of bales whose last layer protrudes from the upper edge of the panels while being sufficiently engaged in the body so that during creep, the latter layer is housed in it -Even substantially in the interior volume of the box.

L'invention a encore pour objet, selon un autre de ses aspects, une caisse destinée à recevoir des balles d'un matériau sensible au fluage, notamment des balles de caoutchouc synthétique, ces balles étant empilées par couches successives dans la caisse jusqu'à une dernière couche, la caisse pouvant se caractériser par le fait qu'elle comporte des panneaux dont la hauteur est choisie de telle sorte que la dernière couche dépasse du bord supérieur des panneaux tout en étant suffisamment engagée dans la caisse pour qu'au cours du fluage, la dernière couche se loge d'elle-même sensiblement dans le volume intérieur de la caisse.Another object of the invention is, according to another of its aspects, a box intended to receive bullets of a material sensitive to creep, in particular synthetic rubber bullets, these bullets being stacked in successive layers in the crate until a final layer, the body being characterized by the fact that it comprises panels whose height is chosen so that the last layer protrudes from the upper edge of the panels while being sufficiently engaged in the box so that during the creep, the last layer is lodged of itself substantially in the interior volume of the body.

La caisse peut être agencée pour recevoir par exemple trente-six balles de caoutchouc synthétique de dimension standard, disposées sur six couches.The box can be arranged to receive for example thirty-six balls of synthetic rubber of standard size, arranged on six layers.

Les dimensions d'une balle de caoutchouc peuvent par exemple être les suivantes.The dimensions of a rubber ball may for example be as follows.

La longueur d'une balle peut être comprise entre environ 680 mm et environ 710 mm inclus.The length of a bale can range from about 680 mm to about 710 mm inclusive.

La largeur d'une balle peut être comprise entre environ 340 et environ 355 mm, cette largeur étant par exemple sensiblement égale à la moitié de la longueur.The width of a bale can be between about 340 and about 355 mm, this width being for example substantially equal to half the length.

La hauteur d'une balle peut être comprise entre environ 160 mm et environ 200 mm.The height of a bale can range from about 160 mm to about 200 mm.

L'invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, un procédé de transfert de marchandises contenues dans une caisse métallique vers une caisse en bois, dans lequel la caisse métallique utilisée comporte quatre panneaux amovibles articulés sur une partie de base, ce procédé pouvant comporter les étapes suivantes :

  • la caisse métallique étant remplie, enlever les quatre panneaux,
  • recouvrir la marchandise reposant sur la partie de base de la caisse métallique par une caisse en bois disposée à l'envers,
  • retourner à 180° la partie de base métallique coiffée par la caisse en bois,
  • enlever la partie de base métallique.
The invention further relates, independently or in combination with the foregoing, to a method of transferring goods contained in a metal crate to a wooden crate, wherein the metal crate used comprises four removable panels hinged to a base portion this method may comprise the following steps:
  • the metal box being filled, remove the four panels,
  • cover the merchandise resting on the base part of the metal crate by a wooden case arranged upside down,
  • return to 180 ° the metallic base part capped by the wooden case,
  • remove the metal base part.

L'invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, une caisse métallique repliable comportant une partie de base de forme générale rectangulaire comportant quatre montants d'angle, et quatre panneaux articulés sur la partie de base, dont deux petit panneaux et deux grands panneaux. La partie de base comporte, sur au moins un côté entre deux montants d'angle, au moins un taquet de retenue d'un panneau correspondant, notamment d'un petit panneau, qui, lui, comporte une traverse inférieure horizontale.The invention further relates, independently or in combination with the foregoing, to a foldable metal case having a base portion of generally rectangular shape having four corner posts, and four panels hinged to the base portion, two of which are small. panels and two large panels. The base portion comprises, on at least one side between two corner posts, at least one retaining latch of a corresponding panel, in particular a small panel, which itself has a horizontal bottom rail.

La caisse, selon cet aspect de l'invention, peut se caractériser par le fait que la traverse inférieure comporte un premier profilé ouvert vers le bas et au moins une ouverture sur l'aile extérieure du profilé.The box, according to this aspect of the invention, can be characterized in that the bottom rail has a first section open downwards and at least one opening on the outer wing of the profile.

Cette ouverture peut permettre de recevoir le taquet lorsque le panneau est rabattu vers l'extérieur.This opening can receive the cleat when the panel is folded outward.

La traverse inférieure peut comporter un axe, notamment un axe plein, s'étendant au moins partiellement entre les ailes du premier profilé, par exemple sur toute la largeur du panneau.The lower crossbar may comprise an axis, in particular a solid axis, extending at least partially between the flanges of the first profile, for example over the entire width of the panel.

La traverse inférieure peut comporter en outre un deuxième profilé de renfort, superposé au premier.The lower rail may further comprise a second reinforcing section, superimposed on the first.

On a représenté à la figure 1 un exemple de caisse repliable 1 en acier, à l'état monté, comportant une partie de base 2 de forme générale sensiblement rectangulaire, reposant sur quatre pieds 3 dont trois seulement sont visibles sur la figure 1, et quatre panneaux 4 articulés sur la partie de base 2 autour d'axes géométriques de rotation horizontaux.We have shown figure 1 an example of a collapsible body 1 of steel, in the assembled state, comprising a base portion 2 of generally rectangular shape, resting on four feet 3, only three of which are visible on the figure 1 and four panels 4 articulated on the base portion 2 around horizontal geometric axes of rotation.

La partie de base 2 comporte quatre côtés 8 et quatre coins 9. Les grands panneaux 4 portent également la référence 4a et les petits panneaux la référence 4b. De même, parmi les quatre côtés 8 de la partie de base 2, les grands côtés portent la référence 8a et les petits côtés la référence 8b.The base portion 2 has four sides 8 and four corners 9. The large panels 4 also bear the reference 4a and the small panels the reference 4b. Likewise, of the four sides 8 of the base part 2, the long sides bear the reference 8a and the short sides the reference 8b.

La caisse 1 pourrait encore être sensiblement cubique et comporter quatre panneaux de largeurs similaires sans que l'on sorte du cadre de la présente invention.The body 1 could still be substantially cubic and have four panels of similar widths without departing from the scope of the present invention.

La partie de base 2 comporte, au niveau de ses coins 9, des montants d'angle 5 constitués dans l'exemple illustré par des profilés de section sensiblement rectangulaire, creux et verticaux.The base portion 2 comprises, at its corners 9, corner posts 5 constituted in the example illustrated by sections of substantially rectangular section, hollow and vertical.

Les montants d'angle 5 sont reliés, sur les côtés 8 de la partie de base, par des traverses horizontales 6.The corner posts 5 are connected on the sides 8 of the base part by horizontal crosspieces 6.

La partie de base comporte également un fond 7 non apparent sur la figure 1 et visible par exemple sur la figure 3.The base portion also has a bottom 7 not apparent on the figure 1 and visible for example on the figure 3 .

Les panneaux 4 comportent chacun une ossature métallique, en acier dans l'exemple considéré, comprenant des montants verticaux latéraux 10 et des traverses horizontales inférieure 12 et supérieure 11. L'ossature métallique comprend en outre des renforts verticaux 13 qui relient les traverses 11 et 12. Des plaques en acier galvanisé 14 sont fixées sur l'ossature métallique.The panels 4 each comprise a metal frame, made of steel in the example in question, comprising lateral vertical uprights 10 and lower horizontal crosspieces 12 and upper 11. The metal frame further comprises vertical reinforcements 13 which connect the sleepers 11 and 12. Galvanized steel plates 14 are fixed to the metal frame.

Les montants 10, les traverses 11 et 12 et les renforts 13 sont constitués de profilés métalliques en acier galvanisé, dans l'exemple illustré.The uprights 10, the crosspieces 11 and 12 and the reinforcements 13 consist of galvanized steel metal sections, in the example illustrated.

Un porte-étiquette 15 peut également être fixé sur au moins un panneau 4.A label holder 15 may also be attached to at least one panel 4.

Les panneaux articulés 4 peuvent se rabattre vers l'intérieur ou vers l'extérieur de la caisse. Les axes géométriques d'articulation des panneaux se situent à des hauteurs différentes, de manière à permettre de rabattre les panneaux les uns sur les autres lorsque la caisse est repliée.The articulated panels 4 can fold inward or outward of the body. The geometric axes of hinge panels are at different heights, so as to fold the panels on each other when the box is folded.

Dans l'exemple illustré, les panneaux sont amovibles relativement à la partie de base 2.In the example shown, the panels are removable relative to the base portion 2.

Des systèmes de verrouillage 17 sont prévus pour maintenir les panneaux 4 ensemble et verticaux quand la caisse est montée. Chaque système de verrouillage 17 peut par exemple comporter une clenche 17a portée par un panneau et pouvant s'engager dans une pièce 17b fixée sur le montant latéral adjacent du panneau voisin.Locking systems 17 are provided to keep the panels 4 together and vertical when the body is mounted. Each locking system 17 may for example comprise a latch 17a carried by a panel and engageable in a part 17b fixed on the adjacent lateral upright of the adjacent panel.

Chaque montant latéral 10 d'un grand panneau 4a est coiffé d'un pion 20. Celui-ci est par exemple engagé inférieurement dans le profilé constituant le montant latéral 10 considéré.Each side upright 10 of a large panel 4a is capped with a pin 20. This is for example engaged lower in the profile constituting the lateral amount 10 considered.

Dans l'exemple illustré, chaque montant latéral 10 d'un grand panneau 4 s'étend, lorsque le panneau est en position verticale, monté sur la partie de base 2, dans le prolongement du montant d'angle 5 sous-jacent.In the illustrated example, each side jamb 10 of a large panel 4 extends, when the panel is in a vertical position, mounted on the base portion 2, in the extension of the underlying corner post 5.

Les pions 20 pourraient aussi, en variante, coiffer les petits panneaux 4b sans que l'on sorte du cadre de la présente invention.The pins 20 could also alternatively cover the small panels 4b without departing from the scope of the present invention.

Un deuxième pion non représenté peut être fixé sur l'extrémité supérieure d'au moins un montant d'angle 5 de la partie de base 2.A second not shown pin may be attached to the upper end of at least one corner post 5 of the base portion 2.

Ce deuxième pion peut être notamment agencé pour s'engager dans une ouverture de l'extrémité inférieure d'un montant latéral 10 d'un panneau lorsque le panneau est monté, et pour s'engager dans une ouverture de l'extrémité inférieure d'un montant d'angle 5 d'une caisse sus-jacente lorsque deux caisses repliées sont gerbées.This second pin may in particular be arranged to engage in an opening of the lower end of a lateral upright of a panel when the panel is mounted, and to engage in an opening of the lower end of the panel. an angle post 5 of an overlying body when two folded cases are stacked.

La partie de base 2 comporte en outre une pluralité de taquets de retenue 21, disposés sur au moins un côté 8 de la partie de base 2 et de préférence sur chaque côté, ces taquets 21 sont agencés de telle sorte que les panneaux 4 puissent venir en appui contre eux, notamment lorsque la pression de la marchandise à l'intérieur de la caisse est importante. Dans l'exemple illustré, la partie de base 2 comporte trois taquets 21 sur ses grands côtés 8a et deux taquets 21 sur ses petits côtés 8b. Le cas échéant, le nombre de taquets 21 pourrait être réduit, par exemple à un seul taquet 21 par côté.The base portion 2 further comprises a plurality of retaining cleats 21, disposed on at least one side 8 of the base portion 2 and preferably on each side, these lugs 21 are arranged so that the panels 4 can come in support against them, especially when the pressure of the goods inside the box is important. In the illustrated example, the base portion 2 comprises three cleats 21 on its long sides 8a and two cleats 21 on its short sides 8b. If necessary, the number of cleats 21 could be reduced, for example to a single cleat 21 per side.

Comme on peut le voir sur les figures 3 et 4, un montant d'angle 5 de la partie de base 2 est pourvu d'une ouverture 30, constituée dans l'exemple considéré par une fente débouchant à l'extrémité supérieure du montant d'angle 5. Cette ouverture 30 est agencée pour coopérer avec un premier élément d'articulation mâle 31 de la traverse inférieure 12 du grand panneau 4a, représenté sur la figure 5, constitué dans l'exemple illustré par une protubérance cylindrique, et pouvant coulisser verticalement dans l'ouverture 30 jusqu'à être désolidarisé du montant d'angle 5.As can be seen on the Figures 3 and 4 a corner post 5 of the base part 2 is provided with an opening 30, constituted in the example in question by a slot opening at the upper end of the corner post 5. This opening 30 is arranged to cooperate with a first male articulation member 31 of the lower cross member 12 of the large panel 4a, shown in FIG. figure 5 , constituted in the example illustrated by a cylindrical protuberance, and slidable vertically in the opening 30 to be detached from the corner post 5.

Comme illustré sur la figure 6, le montant d'angle 5 correspondant à l'autre extrémité du grand côté 8a et coopérant avec le même grand panneau 4a comporte un deuxième élément d'articulation mâle 32, sensiblement identique au premier et constitué dans l'exemple illustré par une protubérance cylindrique.As illustrated on the figure 6 , the corner post 5 corresponding to the other end of the long side 8a and cooperating with the same large panel 4a comprises a second male articulation element 32, substantially identical to the first and constituted in the example illustrated by a cylindrical protuberance .

Cette protubérance 32 est agencée pour coopérer avec une ouverture circulaire 33 de la traverse inférieure 12 du grand panneau 4a, représentée sur la figure 7.This protrusion 32 is arranged to cooperate with a circular opening 33 of the lower cross member 12 of the large panel 4a, shown in FIG. figure 7 .

La forme et les dimensions de la protubérance 32 sont choisies de manière à permettre au grand panneau 4a de pouvoir être désolidarisé complètement de la partie de base 2, le dégagement du deuxième élément d'articulation 32 hors de l'ouverture circulaire 33 devenant possible une fois que le premier élément d'articulation 31 a été extrait de l'ouverture 30.The shape and dimensions of the protuberance 32 are chosen so as to allow the large panel 4a to be completely disconnected from the base part 2, the release of the second hinge member 32 from the circular opening 33 becoming possible. once the first hinge member 31 has been extracted from the opening 30.

La traverse inférieure 12 du grand panneau 4a illustrée à la figure 7 comporte un profilé de section sensiblement circulaire, ouvert au moins partiellement vers l'extérieur en 35.The lower cross member 12 of the large panel 4a illustrated in FIG. figure 7 has a section of substantially circular section, open at least partially outwardly at 35.

La traverse inférieure 12 du grand panneau 4a peut venir en appui contre le taquet 21 de la partie de base 2, comme illustré sur la figure 8, lorsque le grand panneau 4a est vertical.The lower cross member 12 of the large panel 4a can bear against the cleat 21 of the base portion 2, as shown in FIG. figure 8 when the large panel 4a is vertical.

L'ouverture 35 ménagée dans la traverse 12 permet de recevoir les taquets 21 lorsque le grand panneau 4a est rabattu vers l'extérieur, afin que les taquets 21 n'empêchent pas chaque grand panneau 4a de pivoter vers l'extérieur.The opening 35 formed in the cross member 12 to receive the tabs 21 when the large panel 4a is folded outwardly, so that the tabs 21 do not prevent each large panel 4a to pivot outwards.

On a représenté sur les figures 9 à 12 l'agencement d'un petit panneau 4b sur la partie de base 2. Sur la figure 9, le petit panneau 4b est rabattu vers l'extérieur, tandis que sur la figure 10, il est rabattu vers l'intérieur de la caisse et, sur la figure 11, le petit panneau 4b a été démonté. La figure 12 représente uniquement une partie du petit panneau 4b.We have shown on Figures 9 to 12 the arrangement of a small panel 4b on the base part 2. On the figure 9 , the small panel 4b is folded outward, while on the figure 10 it is folded towards the inside of the box and, on the figure 11 , the small panel 4b has been dismantled. The figure 12 represents only a part of the small panel 4b.

Le petit côté 8b de la partie de base 2 comporte un montant d'angle 5 muni, dans l'exemple illustré, d'une ouverture 40 s'étendant sur deux côtés adjacents du montant d'angle 5.The short side 8b of the base portion 2 has a corner post 5 provided, in the illustrated example, with an opening 40 extending on two adjacent sides of the corner post 5.

Comme on peut le voir sur la figure 10, un premier élément d'articulation 41 disposé à une extrémité de la traverse inférieure 12 du petit panneau 4b est engagé dans l'ouverture 40.As can be seen on the figure 10 a first articulation element 41 disposed at one end of the lower cross member 12 of the small panel 4b is engaged in the opening 40.

Cette dernière comporte une partie verticale 40a s'étendant sur le côté du montant d'angle 5 dirigé vers le petit panneau, et une partie horizontale 40b prolongeant l'extrémité supérieure de la partie verticale sur le côté avant du montant d'angle 5. Le premier élément d'articulation 41 peut, une fois amené en haut de la partie verticale 40a de l'ouverture 40, être déplacé à travers la partie horizontale 40b pour être désolidarisé du montant d'angle 5.The latter comprises a vertical part 40a extending on the side of the corner post 5 directed towards the small panel, and a horizontal part 40b extending the upper end of the vertical part on the front side of the corner post 5. The first articulation member 41 can, once brought up the vertical portion 40a of the opening 40, be moved through the horizontal portion 40b to be detached from the corner post 5.

On ne sort pas du cadre de la présente invention lorsque la partie horizontale 40b est réalisée sur le côté arrière adjacent du montant d'angle 5.It is not beyond the scope of the present invention when the horizontal portion 40b is formed on the adjacent rear side of the corner post 5.

Sur l'autre montant d'angle 5 du petit côté 8b de la partie de base 2, une ouverture circulaire 43 est réalisée, étant agencée pour recevoir un deuxième élément d'articulation mâle 44 du petit panneau 4b, disposé à l'autre extrémité de la traverse inférieure 12 et représenté à la figure 12.On the other corner post 5 of the short side 8b of the base part 2, a circular opening 43 is made, being arranged to receive a second male articulation element 44 of the small panel 4b, disposed at the other end of the lower cross member 12 and shown at figure 12 .

Le deuxième élément d'articulation 44 et l'ouverture circulaire 43 correspondante sont agencés de telle sorte que, lorsque l'élément d'articulation 41 est désolidarisé de l'ouverture 40, on puisse désolidariser le deuxième élément d'articulation 44 de l'ouverture circulaire 43, de manière à démonter complètement le petit panneau 4b.The second articulation element 44 and the corresponding circular aperture 43 are arranged in such a way that when the articulation element 41 is disengaged from the opening 40, the second articulation element 44 can be detached from the circular opening 43, so as to completely disassemble the small panel 4b.

On ne sort pas du cadre de la présente invention si l'ouverture circulaire 43 est formée dans la traverse inférieure 12 du petit côté 4b et si un deuxième élément d'articulation 44 est alors réalisé sur le montant d'angle 5 correspondant.It is not beyond the scope of the present invention if the circular opening 43 is formed in the lower cross member 12 of the short side 4b and if a second hinge member 44 is then formed on the corresponding corner post 5.

La caisse illustrée comporte des grands panneaux ayant une épaisseur maximale ea d'environ 30 mm, tandis que les petits panneaux 4b sont d'une épaisseur maximale eb d'environ 20 mm, ainsi qu'illustré sur la figure 13.The illustrated case features large panels having a maximum thickness e of approximately 30 mm, while the small panels 4b have a maximum thickness e b of about 20 mm, as illustrated in figure 13 .

Comme évoqué précédemment, les grands panneaux 4a sont coiffés sur leurs montants verticaux 10 d'un pion 20 de forme semi-pyramidale, comme illustré sur la figure 13. On ne sort pas du cadre de la présente invention si la forme du pion 20 est différente, par exemple tronconique ou autre.As mentioned above, the large panels 4a are capped on their uprights 10 with a pin 20 of semi-pyramidal shape, as shown in FIG. figure 13 . It is not beyond the scope of the present invention if the shape of the pin 20 is different, for example frustoconical or other.

Chaque pion 20 est engagé et fixé, dans l'exemple considéré, dans le montant vertical 10 d'un grand panneau 4a, constitué par un profilé évidé.Each pin 20 is engaged and fixed, in the example considered, in the vertical upright 10 of a large panel 4a, consisting of a hollow profile.

Les petits panneaux 4b, ainsi qu'illustré sur la figure 14, peuvent venir en appui contre des taquets 21 disposés sur les petits côtés 8a de la partie de base 2, ces taquets 21 étant au nombre de deux dans l'exemple considéré.The small panels 4b, as illustrated on the figure 14 may abut against lugs 21 arranged on the short sides 8a of the base portion 2, these lugs 21 being two in number in the example.

La traverse inférieure 12 des petits panneaux 4b comporte, dans l'exemple illustré, ainsi qu'on peut le voir aux figures 14 et 15, un axe 50, ce dernier étant par exemple cylindrique et plein. L'axe est engagé dans un premier profilé 51, ouvert vers le bas, surmonté lui-même d'un deuxième profilé 52 de renfort.The lower cross member 12 of the small panels 4b comprises, in the illustrated example, as can be seen at figures 14 and 15 , an axis 50, the latter being for example cylindrical and solid. The axis is engaged in a first section 51, open downwards, itself surmounted by a second profile 52 of reinforcement.

L'axe 50 peut s'étendre sur toute la longueur de la traverse inférieure 12 et former à ses deux extrémités les deux éléments d'articulation destinés à s'engager respectivement dans les ouvertures 40 et 43.The axis 50 may extend over the entire length of the lower cross member 12 and form at its two ends the two articulation elements intended to engage respectively in the openings 40 and 43.

Les taquets 21 sont agencés de telle sorte que le petit panneau 4b puisse venir en appui contre eux en position verticale.The cleats 21 are arranged such that the small panel 4b can bear against them in vertical position.

Des ouvertures longitudinales 53 ont été réalisées sur l'aile extérieure du profilé inférieur 51. Ces ouvertures 53 sont au nombre de deux dans l'exemple considéré et leur emplacement correspond à celui des taquets 21.Longitudinal openings 53 have been made on the outer flange of the lower profile 51. These openings 53 are two in number in the example in question and their location corresponds to that of the cleats 21.

Ainsi, chaque petit panneau 4b peut venir en appui contre les taquets correspondants 21 par son axe 50.Thus, each small panel 4b can bear against the corresponding stops 21 by its axis 50.

Par ailleurs, les ouvertures 53 permettent de ménager un espace 54 entre l'axe 50 et l'aile supérieure du profilé 51. Cet espace 54 permet d'accueillir les taquets 21 lorsque le petit panneau 4b est rabattu vers l'extérieur.Furthermore, the openings 53 allow to provide a space 54 between the axis 50 and the upper wing of the section 51. This space 54 can accommodate the cleats 21 when the small panel 4b is folded outwardly.

On ne sort pas du cadre de la présente invention si le profilé de renfort 52 est omis, ainsi qu'illustré sur la figure 16.It is not beyond the scope of the present invention if the reinforcing section 52 is omitted, as illustrated in FIG. figure 16 .

Les ouvertures 53 s'étendent sur toute la hauteur du profilé dans l'exemple illustré, mais on ne sort pas du cadre de la présente invention si elles ne s'étendent que sur une partie seulement de cette hauteur.The openings 53 extend over the entire height of the profile in the example illustrated, but it is not beyond the scope of the present invention if they extend only over a portion of this height.

Un pied 3 a été représenté sur la figure 17 en vue de dessous. Il comporte deux côtés sensiblement perpendiculaires 60 et 61. Un socle 62, généralement triangulaire, relie les côtés 60 et 61.A foot 3 has been represented on the figure 17 in view from below. It comprises two substantially perpendicular sides 60 and 61. A base 62, generally triangular, connects the sides 60 and 61.

La hauteur du pied 3 est par exemple d'environ 95 mm.The height of the foot 3 is for example about 95 mm.

Le socle 62 comporte au moins une ouverture 63, deux dans l'exemple illustré, permettant à un liquide de s'écouler, notamment lors de l'étape de galvanisation de l'acier constituant la caisse.The base 62 has at least one opening 63, two in the illustrated example, allowing a liquid to flow, especially during the galvanizing step of the steel constituting the body.

Le montant d'angle 5 comporte une ouverture 64 dans sa partie inférieure, cette ouverture 64 étant formée vers le bas et également latéralement vers l'intérieur, dans l'exemple illustré.The corner post 5 has an opening 64 in its lower part, this opening 64 being formed downwards and also laterally inwards, in the illustrated example.

Le montant d'angle 5 est en retrait par rapport au socle 62, ce qui lui évite de reposer sur le sol et permet également un certain verrouillage d'une caisse sous-jacente lorsque deux caisses à l'état replié sont gerbées, l'extrémité supérieure d'un montant d'angle 5 de la caisse sous-jacente venant se positionner dans le retrait.The amount of angle 5 is set back from the base 62, which avoids it to rest on the ground and also allows some locking of an underlying body when two boxes in the folded state are stacked, the upper end of an amount of angle 5 of the underlying body to be positioned in the withdrawal.

Dans l'exemple considéré, les côtés 60 et 61 du pied 3 ont été découpés en biais sur leur bord adjacent au montant d'angle 5, de manière à faciliter le gerbage des caisses.In the example, the sides 60 and 61 of the foot 3 have been cut obliquely on their edge adjacent to the corner post 5, so as to facilitate the stacking of the boxes.

Les pions 20 peuvent s'engager dans les ouvertures 64 des montants d'angle 5 lors du gerbage de deux caisses et verrouiller ainsi les panneaux d'une caisse sous-jacente à l'état monté.The pins 20 can engage in the openings 64 of the corner posts 5 when stacking two boxes and thus lock the panels of an underlying crate in the assembled state.

Les différentes parties constitutives d'une caisse peuvent être soudées entre elles ou être reliées par d'autres moyens, tels que des rivets ou goupilles par exemple. Certaines soudures sont apparentes sur les figures ; certaines ouvertures circulaires, réalisées dans des profilés notamment, le sont également.The different parts of a box can be welded together or be connected by other means, such as rivets or pins for example. Some welds are apparent in the figures; certain circular openings, made in particular profiles, are also.

Sur la figure 18, on a représenté une variante de réalisation de la caisse de la figure 1, comportant en outre un élément 70 reliant les pieds 3 sous chaque grand panneau 4a. L'élément 70 comporte une semelle 71 et des entretoises 72, au nombre de deux dans l'exemple considéré, reliant la semelle 71 à la traverse 6 de la partie de base 2.On the figure 18 , there is shown a variant embodiment of the body of the figure 1 , further comprising an element 70 connecting the feet 3 under each large panel 4a. The element 70 comprises a sole 71 and spacers 72, two in number in the example, connecting the sole 71 to the cross member 6 of the base portion 2.

Les figures 19 et 20 représentent deux caisses gerbées, respectivement à l'état déplié et replié.The Figures 19 and 20 represent two stacked crates, respectively unfolded and folded.

Dans un exemple de mise en oeuvre de l'invention parmi d'autres, mais préféré, les dimensions de la caisse sont choisies de telle sorte que l'on puisse gerber neuf caisses à l'état replié ou deux caisses à l'état déplié dans un conteneur maritime, de dimensions standards, et que deux caisses puissent tenir de front dans ce conteneur.In an exemplary implementation of the invention among others, but preferred, the dimensions of the box are chosen so that one can stack nine boxes in the folded state or two boxes in the unfolded state in a shipping container, standard dimensions, and that two boxes can stand abreast in this container.

La largeur au niveau de l'espace disponible intérieur d'un conteneur maritime est de l'ordre de 2,33 m. La dimension verticale d'une caisse est avantageusement choisie de manière à ce que la hauteur de deux caisses superposées soit légèrement inférieure à celle de l'espace disponible au passage des portes d'un conteneur maritime, cette hauteur étant comprise entre 2,20 m et 2,30 m.The width at the internal available space of a sea container is of the order of 2.33 m. The vertical dimension of a box is advantageously chosen so that the height of two superimposed boxes is slightly less than that of the space available to the passage of the doors of a sea container, this height being between 2.20 m and 2.30 m.

On ne sort pas du cadre de la présente invention si l'une au moins des ouvertures 30 et 40 est réalisée non pas sur un montant d'angle 5 mais sur un montant latéral 10 d'un panneau, et si l'élément d'articulation mâle correspondant est réalisé sur le montant d'angle 5 correspondant.It is not beyond the scope of the present invention if at least one of the openings 30 and 40 is made not on a corner post 5 but on a lateral amount 10 of a panel, and if the element of Corresponding male articulation is performed on the corresponding corner post 5.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, et l'on peut notamment modifier les dimensions relatives des panneaux et de la partie de base.Of course, the invention is not limited to the embodiments which have just been described, and it is possible in particular to modify the relative dimensions of the panels and the base part.

Toutefois, il est avantageux que la hauteur des panneaux soit choisie de manière à permettre de mettre en oeuvre le procédé de remplissage suivant, qui va être décrit en se référant aux figures 21 à 24.However, it is advantageous for the height of the panels to be chosen so as to allow the following filling method to be implemented, which will be described with reference to the Figures 21 to 24 .

On dispose dans la caisse les balles de caoutchouc B par couches successives, par exemple six couches.In the box are placed the rubber balls B in successive layers, for example six layers.

Les balles de caoutchouc B peuvent par exemple être positionnées en couches alternatives respectivement selon la figure 21 et selon la figure 22. Ainsi, la couche la plus basse comportera par exemple six balles positionnées selon la figure 21 ; la couche suivante comportera six balles disposées selon la figure 22, et la couche encore au-dessus aura des balles à nouveau positionnées selon la figure 21, et ainsi de suite jusqu'à, par exemple, la sixième couche, la plus haute.The rubber balls B can for example be positioned in alternating layers respectively according to the figure 21 and according to the figure 22 . Thus, the lowest layer will comprise for example six balls positioned according to the figure 21 ; the next layer will have six balls arranged according to the figure 22 , and the layer still above will have balls again positioned according to the figure 21 , and so on until, for example, the sixth layer, the highest.

Ce positionnement est possible du fait que la longueur d'une balle, comprise par exemple entre 680 mm et 710 mm, est sensiblement égale au double de sa largeur, comprise par exemple entre 340 mm et 355 mm.This positioning is possible because the length of a bale, for example between 680 mm and 710 mm, is substantially equal to twice its width, for example between 340 mm and 355 mm.

La hauteur des panneaux 4 est choisie de telle sorte que la sixième couche dépasse vers le haut du bord supérieur des panneaux 4, comme on peut le voir sur la figure 23.The height of the panels 4 is chosen so that the sixth layer protrudes upwardly from the upper edge of the panels 4, as can be seen in FIG. figure 23 .

Toutefois, au cours du fluage du caoutchouc, les balles B se tassent et la hauteur de l'empilement diminue, au point que celui-ci arrive sensiblement au niveau des bords supérieurs des panneaux 4, comme illustré sur la figure 24.However, during the creep of the rubber, the balls B are packed and the height of the stack decreases, to the point that it comes substantially at the upper edges of the panels 4, as shown in FIG. figure 24 .

Un tel procédé permet d'accroître la quantité de balles contenues dans une caisse.Such a method makes it possible to increase the quantity of bales contained in a box.

A l'étape représentée à la figure 23, la couche supérieure dépasse du bord supérieur des panneaux d'une hauteur qui est par exemple comprise entre environ 1/4 et environ 8/9 de l'épaisseur initiale d'une balle de caoutchouc. Par exemple, lorsque la hauteur d'une balle est de 190 mm, la hauteur de dépassement par rapport au bord supérieur de la caisse peut être au chargement, de l'ordre de 160 mm environ, la hauteur utile de la caisse étant de 980 mm et les balles étant disposées en six couches superposées.At the step shown in figure 23 , the upper layer protrudes from the upper edge of the panels by a height which is for example between about 1/4 and about 8/9 of the initial thickness of a rubber ball. For example, when the height of a bale is 190 mm, the height of overtaking with respect to the upper edge of the box can be loading, of the order of 160 mm, the useful height of the box being 980 mm and the balls being arranged in six superimposed layers.

L'invention permet également de mettre en oeuvre un procédé de transfert de marchandises, notamment des balles de caoutchouc B, d'une caisse métallique comportant quatre panneaux amovibles et une partie de base, par exemple une caisse 1 selon l'invention, comme illustré, vers une caisse en bois C.The invention also makes it possible to implement a method for transferring goods, in particular rubber balls B, a metal box comprising four removable panels and a base part, for example a box 1 according to the invention, as illustrated. , towards a wooden crate C.

Ce procédé de transfert comporte les étapes suivantes illustrées sur les figures 25 à 29.This transfer method comprises the following steps illustrated on the Figures 25 to 29 .

Les balles B sont disposées au départ à l'intérieur de la caisse métallique 1, comme illustré sur la figure 25.The balls B are initially arranged inside the metal box 1, as shown in FIG. figure 25 .

Les panneaux 4 de cette caisse sont tout d'abord démontés à l'étape illustrée sur la figure 26. Il ne reste que la partie de base 2 de la caisse 1, qui supporte les balles B.The panels 4 of this box are first dismounted at the step illustrated on the figure 26 . There remains only the base part 2 of the body 1, which supports the balls B.

On coiffe les balles B d'une caisse en bois C disposée à l'envers, à l'étape suivante, représentée à la figure 27.The balls B are capped with a wooden box C arranged upside down in the next step, shown in FIG. figure 27 .

On retourne alors l'ensemble en effectuant une rotation de 180°, ainsi qu'illustré sur la figure 28, de manière à ce que la caisse en bois C se trouve sur le sol et que la partie de base recouvre les balles B.Then we turn the assembly 180 ° rotation, as illustrated on the figure 28 , so that the wooden box C is on the floor and the base part covers the balls B.

Dans une dernière étape illustrée à la figure 29, la partie de base 2 est retirée de manière à ce que les balles B se trouvent chargées dans la caisse C en bois.In a last step illustrated in the figure 29 the base part 2 is removed so that the balls B are loaded into the wooden box C.

Dans toute la description, y compris les revendications, l'expression « comportant un » doit être comprise comme étant synonyme de l'expression « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, including the claims, the phrase "having one" should be understood as being synonymous with the phrase "having at least one", unless the contrary is specified.
