Description

La présente invention a trait à la manutention et plus particulièrement au transport d'articles en feuilles tels que des vitrages et notamment des pare-brise ou lunettes arrières de véhicules automobiles.The present invention relates to the handling and more particularly to the transport of sheet articles such as glazing and in particular windshields or rear windows of motor vehicles.

La très grande fragilité de ce type d'articles et la nécessité de charger et décharger fréquemment les dispositifs utilisés donnent naissance à des exigences souvent mal compatibles : une constructtion robuste qui maintienne les feuilles en toute sécurité ainsi qu'une accessibilité aisée et un encombrement réduit.The very great fragility of this type of article and the need to frequently load and unload the devices used give rise to requirements which are often poorly compatible: a robust construction which keeps the sheets in complete safety, as well as easy accessibility and reduced bulk. .

La manutention d'objets de ce genre dans des caisses en bois présente de nombreux inconvénients. Non seulement elle exige des manipulations multiples au chargement comme au déchargement, mais le retour des emballages vides pose un problème d'encombrement. Les pertes de temps et de place, la nécessité d'une main-d'oeuvre importante en font un moyen onéreux de manutention.The handling of such objects in wooden cases has many drawbacks. Not only does it require multiple handling during loading and unloading, but the return of empty packaging poses a problem of space. The loss of time and space, the need for a large workforce make it an expensive means of handling.

On a proposé des dispositifs métalliques, formés d'un plancher muni de seulement trois ridelles verticales destinées à protéger contre les chocs la pluralité de feuilles reposant par leur tranche. L'accessibilité aux feuilles en est facilitée pour le chargement comme pour le déchargement. Toutefois, l'encombrement au retour reste le même.Metal devices have been proposed, formed of a floor provided with only three vertical drop sides intended to protect against impact the plurality of sheets resting by their edges. Accessibility to the sheets is facilitated for loading and unloading. However, the size on the return remains the same.

Pour remédier à cet inconvénient, on a alors réalisé des dispositifs comprenant des ridelles repliables ou démontables. Mais dans un cas se posait un problème de détérioration mécanique, dans l'autre de perte des pièces au cours des allées et venues.To overcome this drawback, devices have then been made comprising foldable or removable drop sides. But in one case there was a problem of mechanical deterioration, in the other of loss of parts during the comings and goings.

La publication de brevet français 2 506 728 décrit un dispositif métallique que présente l'avantage d'un faible encombrement à vide sans nécessiter de démontage. Le dispositif proposé comprend un plancher, une membrure arrière et deux ridelles latérales sensiblement verticales en service, se faisant face et fixées sur deux bords opposés du plancher. Il est caractérisé en ce qu'il s'inscrit dans un volume sensiblement en tronc de pyramide, ce qui autorise un emboîtement immédiat d'un conteneur dans un autre. Toutefois, l'accessibilité du dispositif est encore limitée par la présence des ridelles latérales qui obligent en outre à se limiter à une certaine dimension des feuilles. De plus l'empilage des conteneurs chargés n'est pas envisageable.The French patent publication 2 506 728 describes a metallic device which has the advantage of a small footprint when empty without requiring disassembly. The proposed device comprises a floor, a rear member and two side walls which are substantially vertical in service, facing each other and fixed on two opposite edges. from the floor. It is characterized in that it fits into a volume substantially in the trunk of a pyramid, which allows immediate nesting of one container in another. However, the accessibility of the device is still limited by the presence of the side panels which also make it necessary to be limited to a certain dimension of the sheets. In addition, the stacking of loaded containers is not possible.

Le brevet américain 3 193 093 propose un dispositif de manutention d'articles en feuilles qui autorise un empilage aussi bien en charge qu'à vide. Il est formé d'une base surmontée d'une membrure arrière et d'un cadre avant. Mais l'empilage à vide de plusieurs dispositifs ne peut être effectué qu'en démontant le cadre avant, lequel, n'étant plus solidaire du conteneur doit être, lors du transport, fixé par des moyens supplémentaires afin d'éviter sa perte.US Patent 3,193,093 proposes a device for handling sheet articles which allows stacking both under load and when empty. It consists of a base surmounted by a rear frame and a front frame. However, the stacking of several devices under vacuum can only be carried out by dismantling the front frame, which, being no longer secured to the container, must be, during transport, fixed by additional means in order to avoid its loss.

La présente invention vise à pallier tous ces inconvénients tout en assurant un maintien en toute sécurité des feuilles.The present invention aims to overcome all these drawbacks while ensuring that the sheets are held securely.

Elle se propose notamment de fournir un dispositif de manutention, ou conteneur, d'articles en feuilles, permettant de charger, d'emmaganiser et de décharger lesdits articles en conservant au cours de ces diverses étapes une accessibilité de conteneur sur plusieurs de ses faces.It proposes in particular to provide a handling device, or container, for sheet articles, making it possible to load, store and unload said articles while retaining, during these various stages, container accessibility on several of its faces.

Elle vise également à fournir un conteneur tel qu'on puisse gerber plusieurs conteneurs, les uns au-dessus des autres lorsqu'ils sont chargés, et les uns dans les autres avec un volume d'encombrement réduit au minimum lorsqu'ils sont vides.It also aims to provide a container such that it is possible to stack several containers, one above the other when loaded, and one inside the other with a reduced bulk volume when empty.

L'invention a également pour objet de fournir un conteneur métallique qui supprime tout risque de bris des feuilles et assure une grande sécurité de maintien malgré une diminution notable de la surface métallique.The object of the invention is also to provide a metal container which eliminates any risk of breakage of the sheets and ensures high security of maintenance despite a significant reduction in the metal surface.

Enfin, l'invention a pour objet de fournir un dispositif de manutention qui présente les avantages précités, et qui peut être utilisé sans risque de perte de pièces ou de détérioration mécanique de certains de ces éléments.Finally, the invention aims to provide a handling device which has the aforementioned advantages, and which can be used without risk of loss of parts or mechanical deterioration of some of these elements.

Sous un autre de ses aspects, l'invention a pour objet de fournir un dispositif de manutention d'une pluralité d'articles en feuilles, qui possède des moyens pour maintenir la pluralité d'articles, ainsi que des moyens pour ajuster leur maintien suivant la hauteur, la courbure ou la largeur desdits articles ainsi que suivant l'épaisseur de l'ensemble d'articles ainsi constitué.In another of its aspects, the invention aims to provide a device for handling a plurality of sheet articles, which has means for holding the plurality of articles, as well as means for adjusting their holding according to the height, the curvature or the width of said articles as well as according to the thickness of the set of articles thus constituted.

A cette fin, l'invention propose un dispositif pour la manutension d'articles en feuilles, notamment des vitrages tels que des pare-brise, destiné à recevoir une pluralité de ces articles comprenant une base sensiblement rectangulaire faisant plancher sur laquelle les articles reposent par leur tranche, une membrure arrière verticale, des moyens de gerbage mobiles, des moyens mobiles pour le maintien de la pluralité d'articles (voir US-A- 3 193 093).To this end, the invention provides a device for the handling of sheet articles, in particular glazing such as windshields, intended to receive a plurality of these articles comprising a substantially rectangular base forming the floor on which the articles rest by their edges, a vertical rear member, stacking means mobile, mobile means for holding the plurality of articles (see US-A-3,193,093).

Le dispositif ou conteneur objet de l'invention est remarquable en ce que les moyens de gerbage sont des montants (8) escamotables dans la base (1), inséparables de la base et mobiles entre une première position d'escamotage convenant au gerbage du dispositif à vide et une deuxième position pour le gerbage du dispositif chargé et les moyens de maintien de la pluralité d'articles sont des barres (14) associées à une sangle et déplaçables verticalement, ces barres étant inséparables de la membrure arrière et mobiles entre une première position où ces moyens sanglent ces articles et une deuxième position où ces moyens sont escamotés dans la membrure arrière pour permettre le gerbage du dispositif vide.The device or container object of the invention is remarkable in that the stacking means are uprights (8) retractable in the base (1), inseparable from the base and movable between a first retraction position suitable for stacking the device empty and a second position for stacking the loaded device and the means for holding the plurality of articles are bars (14) associated with a strap and vertically movable, these bars being inseparable from the rear member and movable between a first position where these means strap these articles and a second position where these means are retracted into the rear member to allow stacking of the empty device.

En référence avec la figure 1, on va maintenant décrire un conteneur conforme à l'invention et contenant une pluralité de pare-brise 15, qui comprend un plancher 1 délimité par deux bords latéraux 2, un bord arrière 4 et un bord avant 3. Le dessous du plancher 1 est muni d'une membrure auxiliaire 5 qui, sur chacun des quatre côtés, permet la saisie du conteneur et son transport par un transporteur à fourches grâce à la présence de lumières 6 dont l'écartement coïncide avec celui des fourches.With reference to FIG. 1, we will now describe a container according to the invention and containing a plurality of windshields 15, which comprises a floor 1 delimited by two lateral edges 2, a rear edge 4 and a front edge 3. The underside of the floor 1 is provided with an auxiliary frame 5 which, on each of the four sides, allows the gripping of the container and its transport by a fork conveyor thanks to the presence of lights 6 whose spacing coincides with that of the forks .

Une membrure arrière verticale 9 est fixée au plancher 1. Elle est constituée de quatre montants creux verticaux, soudés au plancher, dont deux référencés 10 sont aux angles et deux référencés 11, sont en position intermédiaire. Ils sont reliés à leur sommet par une barre horizontale 12. Les montants intermédiaires 11 présentent, sur une partie au moins de leur hauteur, deux fentes verticales : l'une 13, est face au plancher et l'autre non représentée est située du côté opposé à la première. Chacun de ces montants 11 sert de logement à une barre mobile 14, profilée en U. Sur la figure 1, une barre 14 est rerésentée en position de fonctionnement, c'est-à-dire hors de son logement 11, en position horizontale et appliquée sur des intercalaires non représentés montés situés sur le bord supérieur de chaque pare-brise de la pile 15.A vertical rear member 9 is fixed to the floor 1. It consists of four vertical hollow uprights welded to the floor, two of which are referenced 10 at the corners and two referenced 11, are in the intermediate position. They are connected at their top by a horizontal bar 12. The intermediate uprights 11 have, on at least part of their height, two vertical slots: one 13, is facing the floor and the other not shown is located on the side opposite the first. Each of these uprights 11 serves as a housing for a movable bar 14, U-shaped. In FIG. 1, a bar 14 is represented in the operating position, that is to say outside of its housing 11, in the horizontal position and applied to spacers not shown mounted on the upper edge of each windshield of the stack 15.

Suivant une variante non représentée de l'invention, il est possible de remplacer les montants 10 par de simples tôles repliées à angle droit et terminées à leur sommet par une partie creuse.According to a variant not shown of the invention, it is possible to replace the uprights 10 by simple sheets folded at right angles and terminated at their top by a hollow part.

On peut de la sorte alléger davantage la structure du dispositif, la partie supérieure creuse étant nécessaire pour permettre le gerbage des conteneurs chargés.It is thus possible to further lighten the structure of the device, the hollow upper part being necessary to allow stacking of the loaded containers.

Chacun des bords 2 du plancher est surmonté à ses extrémités d'épaulements 17. Sur le plancher lui-même, se trouvent des épaulements 18.Each of the edges 2 of the floor is surmounted at its ends by shoulders 17. On the floor itself, there are shoulders 18.

Des montants 8, creux et mobiles, sont, en position verticale, insérés dans des orifices 16 ménagés à cet effet dans le plancher. Les épaulements 17 et 18 délimitent le logement des montants 8 lorsqu'ils sont en positon escamotée. La partie A de la figure 1 sera mieux comprise en relation avec la figure 6. Les montants 8 présentent sur toute leur longueur une fente 19 servant de coulisse et coopérant avec un p ivot 20 fixé horizontalement sur la face interne de l'épaulement 17.Uprights 8, hollow and movable, are, in a vertical position, inserted into holes 16 provided for this purpose in the floor. The shoulders 17 and 18 delimit the housing of the uprights 8 when they are in the retracted position. Part A of Figure 1 will be better understood in relation to FIG. 6. The uprights 8 have over their entire length a slot 19 serving as a slide and cooperating with a bolt 20 fixed horizontally on the internal face of the shoulder 17.

Selon une variante de l'invention, décrite en relation avec la figure 11, on peut prévoir de loger les montants mobiles et escamotables dans le bord avant 3 du conteneur. Cette variante présente l'avantage d'éviter toute gêne de la part des articles chargés dans le conteneur lorsqu'on souhaite monter ou démonter lesdits montants. Les montants référencés 21 sur cette figure ne présentent pas de fente. Les orifices 16 de pose desdits montants 21 sont surmontés d'une pièce 22 profilée en U et munie d'une lumière 23. Chacun des montants 21 est muni d'un écrou 24 qui coopère avec la lumière 23 pour permettre au montant 21 de se ranger dans le bord avant 3 creusé sur toute sa longueur d'un logement 25.According to a variant of the invention, described in connection with FIG. 11, provision can be made to accommodate the mobile and retractable uprights in the front edge 3 of the container. This variant has the advantage of avoiding any discomfort on the part of the articles loaded in the container when it is desired to mount or dismount said uprights. The amounts referenced 21 in this figure do not have a slot. The orifices 16 for fitting said uprights 21 are surmounted by a part 22 that is U-shaped and provided with a lumen 23. Each of the uprights 21 is provided with a nut 24 which cooperates with the lumen 23 to allow the upright 21 to be store in the front edge 3 hollowed out over its entire length of a housing 25.

Quatre ergots 7 sont également prévus dans le prolongement des montants 10 et dans le prolongement des orifices 16 aux quatre coins du conteneur afin de permettre un gerbage des conteneurs chargés par emboîtement des ergots 7 d'un conteneur dans les montants (8, 21) et 10 d'un autre conteneur.Four lugs 7 are also provided in the extension of the uprights 10 and in the extension of the orifices 16 at the four corners of the container in order to allow stacking of the loaded containers by fitting the lugs 7 of a container into the uprights (8, 21) and 10 from another container.

Le plancher 1 peut être uniformément plan, ou posséder une structure nervurée. Les nervures 26 (figure 1) permettent un gain en résistance et en solidité sans qu'il soit nécessaire d'augmenter l'épaisseur de la tôle. Le plancher comprend en outre deux longerons 27 qui s'étendent du bord avant 3 au bord arrière 4, au droit des montants intermédiaires 11. Des crémaillères 28 qui peuvent être en matière plastique ou en caoutchouc sont fixées sur ces longerons 27. Les créneaux de ces crémaillères ont une largeur au moins égale à l'épaisseur des pare-brise à transporter de manière à permettre un calage de la tranche de ces pare-brise.The floor 1 can be uniformly flat, or have a ribbed structure. The ribs 26 (FIG. 1) allow a gain in strength and solidity without it being necessary to increase the thickness of the sheet. The floor further comprises two beams 27 which extend from the front edge 3 to the rear edge 4, in line with the intermediate uprights 11. Racks 28 which may be made of plastic or rubber are fixed to these beams 27. The slots of these racks have a width at least equal to the thickness of the windshields to be transported so as to allow wedging of the edge of these windshields.

Chacun des montants intermédiaires 11 est garni latéralement d'ailes métalliques 29 rapportées. Ces ailes sont recovertes de bande d'un matériau élastique, par exemple une mousse à cellules fermées, de type polyéthylène expansé, et elles servent ainsi d'organe d'appui à la feuille d'extrémité de la pile de pare-brise rangée dans le conteneur.Each of the intermediate uprights 11 is laterally lined with attached metal wings 29. These wings are covered with a strip of elastic material, for example closed cell foam, of the expanded polyethylene type, and they thus serve as a support member for the end sheet of the windshield stack stored in the container.

Suivant une autre variante de l'invention, les montants intermédiaires 11 peuvent être profilés de façon à accueillir un autre type d'organes d'appui pour la feuille d'extrémité de la pile.According to another variant of the invention, the intermediate uprights 11 can be profiled so as to accommodate another type of support member for the end sheet of the stack.

Il est nécessaire de fixer ces organes d'appui en dehors de la structure même des montants afin de ne pas gêner le mouvement des barres profilées 14 dans lesdits montants.It is necessary to fix these support members outside the structure of the uprights so as not to hinder the movement of the profiled bars 14 in said uprights.

C'est pourquoi, selon cette autre variante de l'invention, il peut être prévu de modifier le profil des montants intermédiaires de la façon représentée à la figure 5. La partie avant de chaque montant intermédiaire référencé 30 sur la figure 5 est profilée de façon à présenter une largeur supérieure à celle de la partie arrière, et donc à celle de la barre 14. Les parties 31 qui font saillies latéralement sont régulièrement percées sur au moins une partie de la hauteur du montant, d'ouvertures 32. Ces ouvertures sont prévues pour servir de logements par exemple à des profils en caoutchouc 33 ; ces profils peuvent être introduits à volonté dans lesdites ouvertures sur au moins une partie de la hauteur du montant selon la hauteur de la pile de pare-brise à ranger dans le dispositif. Ils servent ainsi d'organe d'appui pour des vitrages peu bombés qui sont au contact de la palette sur une grande partie de leur surface. Lorsque les vitrages à ranger dans le dispositif de manutention sont très bombés comme certains pare-brise, ils ne sont au contact de la membrure arrière de la palette que sur une faible partie de leur surface, et il n'est pas alors indispensable d'utiliser ces organes d'appui.This is why, according to this other variant of the invention, provision may be made to modify the profile of the intermediate uprights as shown in FIG. 5. The front part of each intermediate upright referenced 30 in FIG. 5 is profiled so as to have a width greater than that of the rear part, and therefore that of the bar 14. The parts 31 which project laterally are regularly drilled over at least part of the height of the upright, with openings 32. These openings are provided to serve as accommodation, for example for rubber profiles 33; these profiles can be introduced at will into said openings over at least part of the height of the upright according to the height of the windshield stack to be stored in the device. They thus serve as a support member for slightly curved glazings which are in contact with the pallet over a large part of their surface. When the glazing to be stored in the handling device is very curved like some windshields, they are only in contact with the rear frame of the pallet on a small part of their surface, and it is not then essential to use these supporting bodies.

Une barre profilée 14 est représentée en détails aux figures 2 et 3. Elle présente une première extrémité 34 légèrement arrondie pour faciliter le passage d'une sangle 35 servant à fixer la pile de pare-brise au conteneur. Cette extrémité présente une anse 36 pour centrer la sangle 35 et saisir la barre quand cela est nécessaire. L'autre extrémit é représentée à la figure 3 est prolongée par une partie cylindrique 37, reliée à la barre par un étranglement 38 dont la largeur est au plus égale à celle des fentes 13.A profiled bar 14 is shown in detail in FIGS. 2 and 3. It has a slightly rounded first end 34 to facilitate the passage of a strap 35 serving to fix the windshield stack to the container. This end has a handle 36 to center the strap 35 and grip the bar when necessary. The other end shown in FIG. 3 is extended by a cylindrical part 37, connected to the bar by a constriction 38 whose width is at most equal to that of the slots 13.

L'arrondi des extrémités de la barre 14 et notamment la partie cylindrique 34 permet d'éviter une usure prématurée de la sangle 35.The rounding of the ends of the bar 14 and in particular the cylindrical part 34 makes it possible to avoid premature wear of the strap 35.

Suivant une caractéristique supplémentaire de l'invention représentée sur la figure 2, la barre 14 est enfilée dans une pièce métallique supplémentaire 39, profilée en L.According to an additional feature of the invention shown in Figure 2, the bar 14 is threaded into an additional metal part 39, shaped in L.

La petite branche 40 du L est prolongée par une visière 41, par exemple de section trapézoïdale, faisant un angle de 160° environ avec la branche 40, et percée de deux fentes 42 pour le passage de la sangle 35. La grande branche 43 est percée d'une fente dont la largeur coïncide avec celle de la barre 14. La branche 43 40 est également recouverte d'un coussin 44 en un caoutchouc cellulaire par exemple.The small branch 40 of the L is extended by a visor 41, for example of trapezoidal section, making an angle of about 160 ° with the branch 40, and pierced with two slots 42 for the passage of the strap 35. The large branch 43 is pierced with a slot whose width coincides with that of the bar 14. The branch 43 40 is also covered with a cushion 44 in cellular rubber for example.

Avec les moyens de l'invention et sans aucun démontage de pièces, on peut empiler des pare-brise, les fixer, les maintenir, empiler les conteneurs chargés, les décharger, empiler les conteneurs vides, de la façon suivante :With the means of the invention and without any disassembly of parts, we can stack windshields, fix them, maintain them, stack the loaded containers, unload them, stack the empty containers, as follows:

Le conteneur prêt à être chargé est accessible par quatre de ses faces, les côtés, l'avant et le dessus ; les barres 14 sont escamotées dans les montants 11, les montants 8, dans une première variante, sont logés le long des bords 2 du plancher, entre les épaulements 17 et 18. Dans une deuxième variante (figure 11), les montants 21 sont logés dans la partie creuse 25 du bord avant 3 du plancher. On pose le premier pare-brise contres les ailes 29, dans le premier créneau des crémaillères 28. On pose sur le bord supérieur du pare-brise un élément intercalaire non représenté pour le séparer d'avec le suivant. Un tel élément peut être un cavalier du type décrit dans la demande de brevet 81 10684, ou un intercalaire profilé en L et décrit dans la demande de brevet français 83 11163 ou une combinaison des deux.The container ready to be loaded is accessible by four of its sides, sides, front and top; the bars 14 are retracted in the uprights 11, the uprights 8, in a first variant, are housed along the edges 2 of the floor, between the shoulders 17 and 18. In a second variant (Figure 11), the uprights 21 are housed in the hollow part 25 of the front edge 3 of the floor. The first windshield is placed against the wings 29, in the first rack tooth 28. An intermediate element, not shown, is placed on the upper edge of the windshield to separate it from the next. Such an element can be a jumper of the type described in patent application 81 10684, or an L-shaped spacer and described in French patent application 83 11163 or a combination of the two.

Puis on continue à empiler les pare-brise l'un après l'autre. Lorsque la pile est achevée, on dégage les barres profilées 14 des montants 11 où elles sont logées en les saisissant par l'anse 36. Lorsque l'étranglement 38 arrive au sommet du montant 11, on fait basculer la barre 14 pour l'amener en position horizontale. On pose chacune des barres 14 sur les intercalaires qui séparent les pare-brise en les faisant éventuellement coulisser le long des fentes 13 des montants 11, grâce à l'étranglement 38, de façon à les ajuster suivant la hauteur des pare-brise.Then we continue to stack the windshields one after the other. When the stack is completed, the profiled bars 14 are released from the uprights 11 where they are housed by gripping them by the handle 36. When the constriction 38 arrives at the top of the upright 11, the bar 14 is tilted to bring it in horizontal position. Each of the bars 14 is placed on the spacers which separate the windshields by possibly sliding them along the slots 13 of the uprights 11, by means of the throttle 38, so as to adjust them according to the height of the windshields.

La sangle 35, de façon connue en soit, vient fixer la pluralité d'articles au conteneur. Elle passe sur la barre 14 et vient se fixer sur le bord 3 du plancher à l'aide d'un crochet métallique 45 venant s'insérer dans une anse 46 solidaire du bord 3 ; elle est fixée à l'arrière du conteneur par un système de grenouillère, connu en soi et non représenté, et qui assure la tension de la sangle après le chargement des pare-brise. A la place d'une grenouillère, on peut aussi utiliser un tendeur à rochet du type "Spanset" muni d'un poussoir à ressort et disponible dans le commerce.The strap 35, in a manner known per se, fixes the plurality of articles to the container. It passes over the bar 14 and is fixed on the edge 3 of the floor using a metal hook 45 coming to be inserted in a handle 46 secured to the edge 3; it is fixed to the rear of the container by a latch system, known per se and not shown, and which ensures the tension of the strap after loading the windshields. Instead of a sleepsuit, it is also possible to use a ratchet tensioner of the "Spanset" type fitted with a spring plunger and commercially available.

La fente ménagée le long des montants intermédiaires 11, et située du côté opposé à la fente 13, permet le passage de la sangle 35 lorsque dans sa position horizontale la barre 14 coulisse le long du montant 11.The slot formed along the intermediate uprights 11, and located on the side opposite to the slot 13, allows the passage of the strap 35 when in its horizontal position the bar 14 slides along the upright 11.

Dans une autre variante, en relation avec la figure 5, les barres 14 sont escamotées dans des montants 30. Dans ce cas, pour constituer les organes d'appui du premier article on a disposé un certain nombre de profils 33 sur la hauteur des montants 30. On procède de façon analogue pour charger une pluralité d'articles.In another variant, in relation to FIG. 5, the bars 14 are retracted in uprights 30. In this case, for constitute the support members of the first article, a certain number of profiles 33 have been placed on the height of the uprights 30. The procedure is similar for loading a plurality of articles.

Suivant une caractéristique supplémentaire de l'invention, il est possible d'ajuster le maintien de la pluralité d'articles selon l'épaisseur de l'ensemble d'articles, à l'aide d'organes supplémentaires précédemment décrits avec la figure 2. On fait passer la sangle dans les fentes 42 de la pièce 39 que l'on fait coulisser le l ong de la barre 14, jusqu'à s'appuyer contre le dernier pare-brise. La présence du coussin 44 permet d'amortir le contact entre ledit pare-brise et la pièce 39, d'éviter des bris de vitrage, et d'éviter également la chute du dernier intercalaire. La pression de maintien du dernier vitrage est alors assurée par le pivotement de la forme profilée en U 39 dont la visière 41 est sollicitée vers le bas au moyen de la sangle 35. De ce fait l'ensemble de la pièce pivote et vient prendre appui sur le dernier vitrage. On tend alors la sangle comme précédemment grâce à un système connu en soi, de grenouillère, ou de tendeur à rochet.According to an additional characteristic of the invention, it is possible to adjust the maintenance of the plurality of articles according to the thickness of the set of articles, using additional members previously described with FIG. 2. The strap is passed through the slots 42 of the part 39 which the l ong of the bar 14 is made to slide, until it rests against the last windshield. The presence of the cushion 44 makes it possible to absorb the contact between said windshield and the part 39, to avoid glass breakage, and also to avoid the fall of the last interlayer. The pressure to maintain the last glazing is then ensured by the pivoting of the U-shaped profile 39, the visor 41 of which is biased downwards by means of the strap 35. As a result, the entire part pivots and comes to bear. on the last window. The strap is then stretched as before thanks to a system known per se, of a sleeper, or of a ratchet tensioner.

L'invention a également pour objet un conteneur dans lequel on peut placer et maintenir une pluralité de pare-brise de courbure différente. Cet aspect de l'invention est décrit à l'aide de la figure 4.The invention also relates to a container in which a plurality of windshields of different curvature can be placed and maintained. This aspect of the invention is described using FIG. 4.

Suivant cet aspect de l'invention, les longerons qui supportent les crémaillères 28 ne sont plus directement soudés au plancher. Ce sont des traverses 47 rendues mobiles par translation le long de deux barres longitudinales 48 creuses et fendues sur toute leur longueur. Ces barres 48 sont rapportées respectivement sur le bord avant 3 et le bord arrière 4 du plancher 1. Par le biais des fentes 49 et des lumières 50 pratiquées à chaque extrémité des traverses 47, l'écartement des traverses de leur inclinaison par rapport aux barres 48 est réglable suivant la courbure des articles chargés. La position des traverses sur les barres 48 est fixée au moyen d'écrous 51.According to this aspect of the invention, the side members which support the racks 28 are no longer directly welded to the floor. These are cross members 47 made mobile by translation along two longitudinal bars 48 hollow and split over their entire length. These bars 48 are attached respectively to the front edge 3 and the rear edge 4 of the floor 1. By means of the slots 49 and the slots 50 formed at each end of the crosspieces 47, the spacing of the crosspieces of their inclination relative to the bars 48 is adjustable according to the curvature of the loaded articles. The position of the crosspieces on the bars 48 is fixed by means of nuts 51.

Le conteneur ainsi chargé d'une pluralité de pare-brise est encore accessible par trois de ses faces, ce qui facilite toute opération de déplacement, tout en assurant un parfait maintien des pare-brise.The container thus loaded with a plurality of windshields is still accessible by three of its faces, which facilitates any movement operation, while ensuring perfect maintenance of the windshields.

Il est généralement souhaitable, lors du transport des conteneurs chargés, de les gerber les uns sur les autres afin de réduire leur encombrement. On procède de la façon suivante, décrite en relation avec les figures 1 et 6 :
   On fait coulisser chacun des montants 8 le long de son logement délimité par les épaulements 17 et 18 de l'arrière vers l'avant du conteneur puis lorsqu'il vient buter contre le pivot 20, on le fait pivoter pour l'amener en position verticale à l'aplomb de l'orifice 16 dans lequel il vient s'insérer. Cette solution présente l'avantage de pouvoir amener les montants en position verticale sans être gêné par l'encombrement des articles chargés.It is generally desirable, when transporting loaded containers, to stack them on top of each other in order to reduce their bulk. The procedure is as follows, described in relation to FIGS. 1 and 6:
We slide each of the uprights 8 along its housing delimited by the shoulders 17 and 18 from the rear towards the front of the container then when it abuts against the pivot 20, it is pivoted to bring it into vertical position perpendicular to the orifice 16 in which it is inserted. This solution has the advantage of being able to bring the uprights into a vertical position without being hindered by the bulk of the loaded articles.

Une autre manière d'opérer est possible avec les moyens de l'invention : on soulève le montant de bas en haut, et d'arrière en avant, et il vient s'insérer dans l'orifice 16.Another way of operating is possible with the means of the invention: the upright is raised from the bottom up, and from back to front, and it is inserted into the orifice 16.

Le conteneur est alors prêt à être gerbé sur un autre conteneur préparé de la même façon. Les ergots 7 du conteneur supérieur viennent s'insérer dans les creux des quatre montants en position d'angle du conteneur inférieur.The container is then ready to be stacked on another container prepared in the same way. The lugs 7 of the upper container are inserted into the hollows of the four uprights in the corner position of the lower container.

Le déchargement des pare-brise a lieu de façon très simple. On commence par escamoter les montants 8 dans leur logement pour faciliter l'accessibilité au conteneur. On choisit, suivant l'encombrement des pare-brise, l'une ou l'autre des solutions précédemment indiquées pour amener les montants 8 en position verticale, pour cette fois les amener en position horizontale : si l'opérateur risque d'être gêné par les pare-brise, on soulève le montant hors de l'orifice 16 jusqu'à ce qu'il vienne en butée contre le pivot 20, on le fait pivoter vers l'avant hors du conteneur et on le fait coulisser dans son logement. On peut aussi utiliser la variante relative à la figure 11. On soulève l'un des montants 21 jusqu'à ce que l'écrou 24 vienne en butée à l'extrémité de la lumière 23 et on le fait pivoter autour de l'axe défini par l'écrou 24 dans la partie creuse 25. On procède ensuite de la même façon avec le deuxième montant que l'on rabat sur le premier.Unloading the windshields is very simple. We start by retracting the uprights 8 in their housing to facilitate accessibility to the container. We choose, depending on the size of the windshields, one or the other of the solutions indicated above to bring the uprights 8 in a vertical position, for this time bring them in a horizontal position: if the operator risks being hampered by the windshields, the upright is raised out of the orifice 16 until it comes into abutment against the pivot 20, it is pivoted forwards out of the container and it is made to slide in its housing . One can also use the variant relating to FIG. 11. One of the uprights 21 is lifted until the nut 24 abuts at the end of the lumen 23 and it is made to pivot around the axis defined by the nut 24 in the hollow part 25. Then we proceed in the same way with the second upright that we fold over the first.

On décroche la sangle 35, on soulève la barre 14 par son anse 36 jusqu'à l'amener en position verticale et on la fait coulisser dans le montant (11, 30). Les pare-brise sont alors totalement accessibles et on peut procéder à le ur déchargement sans aucun risque de perte ou de détérioration de pièces. Dans le cas où les intercalaires posés sur les tranches supérieures des pare-brise pour les séparer les uns des autres sont ceux décrits dans la demande de brevet français 83 11163, il est avantageux que le plancher 1 du conteneur présente les nervures 26 : elles définissent des bacs 52 qui permettent de recueillir les intercalaires qui tombent lorsque les pare-brise sont prélevés.The strap 35 is unhooked, the bar 14 is lifted by its handle 36 until it is brought to a vertical position and it is made to slide in the upright (11, 30). The windshields are then fully accessible and can be unloaded without any risk of loss or deterioration of parts. In the case where the spacers placed on the upper edges of the windshields to separate them from each other are those described in French patent application 83 11163, it is advantageous for the floor 1 of the container to have the ribs 26: they define bins 52 which collect the dividers which fall when the windshields are removed.

Lorsque le plancher du conteneur est vide, on peut également gerber plusieurs conteneurs. On superpose un conteneur sur l'autre plancher contre plancher et membrure arrière contre membrure arrière de façon non représentée. On gerbe au moins six conteneurs l'un par dessus l'autre.When the container floor is empty, several containers can also be stacked. One container is stacked on top of the other floor against floor and rear frame against rear frame not shown. We stack at least six containers one on top of the other.

Les figures 7 à 9 ainsi que la figure 12 illustrent une variante de l'invention dans laquelle les moyens mobiles et escamotables de maintien des piles d'articles comprennent des moyens de maintien latéral ainsi que des moyens d'ajustement du maintien suivant la largeur des articles.FIGS. 7 to 9 as well as FIG. 12 illustrate a variant of the invention in which the mobile and retractable means for holding the stacks of articles comprise lateral holding means as well as means for adjusting the holding along the width of the articles.

Ces moyens disposés de chaque côté du conteneur, comprennent deux bras de levier 54 au sommet desquels se trouve soudée une barre tubulaire 55. Une cornière métallique 56 est disposée à la base des bras de leviers 54 afin de donner une certaine rigidité à la structure. Elle est percée d'une lumière 58 qui coopère avec un écrou 57 fixé sur le bras 54 pour permettre le pivotement dudit bras de sorte que le bras est solidaire de la cornière. L'une des ailes 70 de la cornière a un profil en forme de chaise dont l'assise repose sur le bord latéral 2 du conteneur. La partie abaissée 71 du profil sert d'appui à un fer plat 59, disposé parallèlement au bord latéral 2 du conteneur au niveau du plancher, c'est-à-dire légèrement abaissé par rapport à celui du bord latéral et soudé à ladite partie 71. Deux barres cylindriques 60 sont d'une part adossées et soudées à la cornière et d'autre part soudées au fer plat 59 qui assure le maintien de leur écartement.These means disposed on each side of the container, include two lever arms 54 at the top of which is welded a tubular bar 55. A metal angle 56 is arranged at the base of the lever arms 54 in order to give a certain rigidity to the structure. It is pierced with a light 58 which cooperates with a nut 57 fixed on the arm 54 to allow the pivoting of said arm so that the arm is integral with the angle iron. One of the wings 70 of the angle iron has a chair-shaped profile, the seat of which rests on the lateral edge 2 of the container. The lowered part 71 of the profile serves as a support for a flat iron 59, arranged parallel to the lateral edge 2 of the container at floor level, that is to say slightly lowered relative to that of the lateral edge and welded to said part 71. Two cylindrical bars 60 are on the one hand leaned and welded to the angle iron and on the other hand welded to the flat iron 59 which maintains their spacing.

Une pièce en équerre 61 dont l'extrémité est constituée par un anneau 62 est rapportée sur les fers plats 59. La fente 62 est destinée au passage d'une sangle 69 représentée à la figure 12 et qui relie les deux fers plats. La sangle 69 peut être tendue ou détendue au moyen d'un tendeur à rochet non représenté, mais susceptible de se loger dans une ouverture 72 ménagée à cet effet sur l'un des bords 2 du conteneur. La sangle passe sous les longerons 27 dans des ouvertures 73 prévues à cet effet.A square piece 61 whose end consists of a ring 62 is attached to the flat bars 59. The slot 62 is intended for the passage of a strap 69 shown in Figure 12 and which connects the two flat bars. The strap 69 can be stretched or relaxed by means of a ratchet tensioner not shown, but capable of being housed in an opening 72 formed for this purpose on one of the edges 2 of the container. The strap passes under the longitudinal members 27 in openings 73 provided for this purpose.

La figure 10 illuste une variante d'un conteneur et notamment d'un plancher particulièrement adapté pour recevoir et escamoter les moyens de maintien latéral précédemment décrits.Figure 10 illustrates a variant of a container and in particular of a floor particularly suitable for receiving and retracting the lateral holding means described above.

Le fond du conteneur comporte une partie pleine 63 entre les longerons 27 de support des crémaillères. Cette partie pleine est entourée de chaque côté de parties creuses (64, 65, 66).The bottom of the container has a solid portion 63 between the side rails 27 for supporting the racks. This solid part is surrounded on each side by hollow parts (64, 65, 66).

Perpendiculairement aux longerons 27 et de part et d'autre desdits longerons sont disposées deux paires de profilés transversaux en L 67 qui délimitent les différentes parties creuses. L'une des paires a un écartement inférieure à celui de l'autre.Perpendicular to the side members 27 and on either side of said side members are arranged two pairs of transverse profiles in L 67 which delimit the different hollow parts. One of pairs has a spacing less than that of the other.

Sur la figure 10, on a représenté des montants intermédiaires 30 déjà décrits. On a également représenté des évidements supplémentaires 68 de centrage des ergots 7 pour le gerbage des conteneurs vides.In Figure 10, there is shown intermediate amounts 30 already described. There have also been shown additional recesses 68 for centering the lugs 7 for stacking empty containers.

Le montage et l'escamotage des moyens de maintien latéral fonctionne de la façon suivante :The mounting and retraction of the lateral holding means works as follows:

Lorsque le conteneur est vide, les bras de levier 54 sont repliés sur les barres cylindriques 60 qui sont escamotées sur le plancher, les deux paires de barres étant plus ou moins rapprochées l'une de l'autre.When the container is empty, the lever arms 54 are folded over the cylindrical bars 60 which are retracted on the floor, the two pairs of bars being more or less close to each other.

Avant de commencer le remplissage du conteneur, on relève les barres tubulaires 55 des éléments de maintien latéral, on amène ainsi les bras de levier 54 en position verticale et on les met en place en fin de course, sur les bords latéraux 2 du conteneur. On met en place le premier article, par exemple une lune tte chauffante, en l'appuyant contres les organes d'appui, et on l'axe par rapport au conteneur. On ajuste l'un des éléments de maintien latéral contre ledit premier artcle en agissant sur un tendeur à rochet non représenté. On laisse la deuxième barre 55 à l'extrémité du conteneur. On poursuit la formation du chargement en posant un intercalaire dans l'axe de chaque montant intermédiaire entre chaque article.Before starting to fill the container, the tubular bars 55 are raised from the lateral holding elements, the lever arms 54 are thus brought into a vertical position and they are placed at the end of the travel, on the lateral edges 2 of the container. The first article is put in place, for example a heating head moon, by pressing it against the support members, and it is axis relative to the container. One of the lateral holding elements is adjusted against said first artcle by acting on a not shown ratchet tensioner. The second bar 55 is left at the end of the container. The formation of the load is continued by placing an interlayer in the axis of each intermediate post between each article.

Lorsque le chargement est achevé, le maintien des articles par les barres 14 se fait de la façon déjà décrite. On procède alors à l'ajustement du maintien latéral en agisssant sur le tendeur à rochet pour rapprocher le deuxième élément de maintien latéral et le bloquer contre l'ensemble d'articles.When the loading is complete, the articles are held by the bars 14 in the manner already described. We then proceed to the adjustment of the lateral support by acting on the ratchet tensioner to bring the second lateral support element closer and block it against the set of articles.

Pour escamoter les éléments de maintien latéral, on agit sur le tendeur à rochet pour écarter les deux éléments, on vide le conteneur, et on replie les bras de levier 54 sur les barres cylindriques 60 en faisant coulisser ces dernières dans le plancher sur les profilés transversaux en L 67. Les barres 60 coulissent dans les profilés transversaux 67 en entraînant avec elles tout le système de maintien dont elles sont solidaires. Elles peuvent venir se loger sur la partie 63 du plancher en passant dans les ouvertures 74 prévues à cet effet dans les longerons 27.To retract the lateral holding elements, one acts on the ratchet tensioner to separate the two elements, the container is emptied, and the lever arms 54 are folded over the cylindrical bars 60 by sliding the latter in the floor on the profiles transverse in L 67. The bars 60 slide in the transverse sections 67, carrying with them the whole holding system of which they are integral. They can be housed on the part 63 of the floor by passing through the openings 74 provided for this purpose in the side members 27.

La possibilité de faire coulisser les barres 60 permet d'ajuster le maintien latéral suivant la largeur des articles.The possibility of sliding the bars 60 makes it possible to adjust the lateral support according to the width of the articles.

Grâce à la différence d'écartement entre les deux paires de profilés transversaux 67 et de barres cylindriques 60, on peut rapprocher l'un de l'autre de façon notable les deux moyens de maintien latéral. On peut alors assurer le maintien d'articles de faible dimension.Thanks to the difference in spacing between the two pairs of transverse profiles 67 and cylindrical bars 60, it is possible to bring the two lateral holding means closer to one another. We can then ensure the maintenance of small items.

Pour mettre en évidence l'efficacité des moyens de l'invention, on a réalisé des essais de transport d'articles en verre. Avec la forme de réalisation préférée de l'invention, qui comprend des moyens de maintien latéral, on peut transporter sans aucun endommagement jusqu'à 700 kg de verre, sous la forme par exemple de 50 pare-brise feuilletés environ ou de 45 feuilles de verre fortement bombées.To demonstrate the effectiveness of the means of the invention, tests were carried out for transporting glass articles. With the preferred embodiment of the invention, which comprises lateral holding means, up to 700 kg of glass can be transported without any damage, for example in the form of about 50 laminated windshields or 45 sheets of heavily curved glass.
