Description

La présente invention concerne le domaine des équipements de stockage et de conditionnement, en particulier des conteneurs pour le transport ou la manipulation groupé(e), de produits, de composants ou de pièces, notamment de composants ou d'ensembles utiles pour la fabrication de machines ou de véhicules, en particulier à la chaîne.The present invention relates to the field of storage and packaging equipment, in particular containers for the transport or group handling (e), of products, components or parts, in particular components or assemblies useful for the manufacture of machines or vehicles, especially to the chain.

L'invention a pour objet un dispositif pour le verrouillage d'un montant d'un tel conteneur, ainsi qu'un conteneur dont les montants (qui soutiennent les parois latérales) sont équipés de tels dispositifs de verrouillage amovible en position relevée ou redressée.The invention relates to a device for locking an amount of such a container, and a container whose uprights (which support the side walls) are equipped with such removable locking devices in the raised or rectified position.

Le point commun des différentes déclinaisons de conteneurs évoqués ci-dessus est de pouvoir être repliés à vide, pour limiter leur encombrement.The common point of the different types of containers mentioned above is to be folded empty, to limit their size.

A cet effet, ces conteneurs possèdent des montants repliables qui peuvent être généralement pivotés entre une position redressée ou relevée, dans laquelle ils servent de supports aux parois latérales délimitant le volume intérieur utile du conteneur, et une position repliée de non-utilisation et de rangement, en particulier en vue de leur transport en retour à vide.For this purpose, these containers have collapsible amounts that can be generally rotated between a rectified or raised position, in which they serve as supports for the side walls defining the useful interior volume of the container, and a folded position of non-use and storage , in particular with a view to their empty return transport.

Des conteneurs de ce type sont, à titres d'exemples, connus des documents suivants : FR-A-2 732 668 , EP-A-1 201 549 et demande de brevet européen n° 05360041.7 du 17 octobre 2005.Containers of this type are, by way of example, known from the following documents: FR-A-2,732,668 , EP-A-1 201 549 and patent application No. 05360041.7 of October 17, 2005.

Ces conteneurs connus comportent en particulier, au niveau de chaque montant, un dispositif de verrouillage amovible en position redressée de ce montant rabattable ou repliable. Ils sont généralement à embase à structure plane et à pourtour carré ou rectangulaire et pourvus de quatre montants assemblés de manière pivotante par leurs extrémités inférieures respectives avec ladite embase, chacun au niveau d'un coin de cette dernière. Ces montants peuvent être déplacés en pivotement entre une position redressée dans laquelle ils sont sensiblement positionnés perpendiculairement au plan de l'embase et une position repliée ou rabattue le long d'un bord latéral de l'embase, dans laquelle ils sont inclinés en direction de l'embase ou disposés parallèlement à celle-ci, en reposant éventuellement sur ladite embase par leur extrémité libre. Le dispositif de verrouillage évoqué ci-dessus est constitué par deux moyens complémentaires coopérant par engagement mutuel pour bloquer ou verrouiller automatiquement le montant auquel il est associé, en position redressée de ce dernier, un desdits moyens étant solidaire du montant et l'autre desdits moyens étant solidaire de l'embase, ledit blocage ou verrouillage pouvant être libéré par action sur l'un au moins desdits deux moyens.These known containers include in particular, at each amount, a removable locking device in the upright position of the collapsible or collapsible amount. They are generally flanged with a flat structure and with a square or rectangular periphery and provided with four uprights pivotally assembled by their respective lower ends with said base, each at a corner thereof. These posts can be pivotally displaced between a rectified position in which they are substantially positioned perpendicularly to the plane of the base and a folded or folded position along a lateral edge of the base, in which they are inclined in the direction of the base or arranged parallel thereto, possibly resting on said base by their free end. The locking device mentioned above consists of two means complementary cooperating by mutual commitment to block or automatically lock the amount with which it is associated, in the rectified position thereof, one of said means being integral with the amount and the other of said means being secured to the base, said locking or locking can be released by action on at least one of said two means.

Dans certaines applications, ces dispositifs de verrouillage connus montrent leurs limites, ce du fait de la fourniture d'une unique possibilité d'interconnexion ou d'engagement mutuel des deux moyens complémentaires et donc d'une unique position de verrouillage.In certain applications, these known locking devices show their limits, because of the provision of a single possibility of interconnection or mutual engagement of the two complementary means and therefore of a single locking position.

Il est donc obligatoire d'amener le montant concerné exactement dans sa position de verrouillage pour que l'effet de blocage soit obtenu, ce qui peut se révéler fastidieux, en cas de répétition fréquente et/ou de déformation du montant et/ou de l'embase concerné(e)(s).It is therefore mandatory to bring the amount concerned exactly in its locking position so that the locking effect is obtained, which can be tedious, in case of frequent repetition and / or deformation of the amount and / or the concerned base (s).

De plus, tous les efforts tendant à solliciter les montants en-dehors de leur position verrouillée sont repris au niveau d'une unique interface de contact entre les deux moyens complémentaires. Par conséquent, cette interface doit être dimensionnée en adéquation avec cette reprise d'effort, ce qui entraîne des amplitudes de manoeuvre importantes au verrouillage et au déverrouillage.In addition, all efforts tending to solicit amounts outside their locked position are taken up at a single contact interface between the two complementary means. Therefore, this interface must be dimensioned in adequacy with this recovery of effort, resulting in significant maneuvering amplitudes to locking and unlocking.

Enfin, la présence d'une unique interface d'interconnexion ou d'engagement mutuel aboutira forcément à la subsistance d'un jeu en position verrouillée, notamment après une certaine période d'utilisation du conteneur, ce qui peut rendre le gerbage desdits conteneurs délicat et risqué.Finally, the presence of a single interface interconnection or mutual engagement will necessarily result in the maintenance of a game in locked position, especially after a certain period of use of the container, which can make the stacking of said containers delicate and risky.

La présente invention a notamment pour objet de surmonter au moins certains des inconvénients précités.The present invention is intended to overcome at least some of the aforementioned drawbacks.

A cet effet, la présente invention a pour principal objet un dispositif de verrouillage amovible en position redressée d'un montant rabattable ou repliable d'un conteneur, tel qu'évoqué ci-dessus, ce dispositif étant caractérisé en ce que chaque moyen complémentaire comporte au moins deux dents ou crans fournissant par coopération, en fonction de leur configuration d'engagement mutuel, au moins deux positions verrouillées ou bloquées en pivotement distinctes pour le montant concerné, dont l'une correspond à sa position redressée et dont l'autre ou les autres correspond(ent) à une ou des position(s) proche(s) de cette position redressée, mais décalée(s) en direction de la position repliée de ce montant.To this end, the present invention has for main object a removable locking device in the upright position of a collapsible or collapsible amount of a container, as evoked above, this device being characterized in that each complementary means comprises at least two teeth or notches providing by cooperation, according to their mutual engagement configuration, at least two separate locked or locked pivot positions for the amount concerned, one of which corresponds to its upright position and the other of which the others correspond to a position or positions close to this rectified position, but staggered towards the folded position of this amount.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue partielle en perspective d'un montant d'un conteneur à l'état replié, montrant les deux moyens complémentaires du dispositif de verrouillage associé à ce montant ;
  • la figure 2 est une vue partielle en perspective du montant de la figure 2, ledit montant étant presque en position relevée et les deux moyens complémentaires coopérant partiellement ;
  • la figure 3 est une vue partielle en perspective du montant des figures 1 et 2, ledit montant étant dans sa position relevée ou redressée avec coopération avec engagement mutuel complet des deux moyens complémentaires ;
  • la figure 4 est une vue en élévation latérale d'un dispositif de verrouillage en position redressée du montant, selon une variante de réalisation de l'invention, et,
  • la figure 5 est une vue en élévation latérale de l'ensemble [montant / dispositif de verrouillage / pied du conteneur] représenté sur la figure 3.
The invention will be better understood, thanks to the following description, which refers to preferred embodiments, given by way of non-limiting examples, and explained with reference to the appended diagrammatic drawings, in which:
  • the figure 1 is a partial perspective view of an amount of a container in the folded state, showing the two complementary means of the locking device associated with this amount;
  • the figure 2 is a partial perspective view of the amount of the figure 2 , said upright being almost in the raised position and the two complementary means cooperating partially;
  • the figure 3 is a partial perspective view of the amount of figures 1 and 2 , said amount being in its raised or rectified position with cooperation with full mutual commitment of the two complementary means;
  • the figure 4 is a side elevational view of a locking device in the upright position of the upright, according to an alternative embodiment of the invention, and
  • the figure 5 is a side elevation view of the [amount / lockout / container foot] assembly shown on the figure 3 .

Les figures 1 à 4 représentent un dispositif 1 de verrouillage amovible en position redressée d'un montant 3 rabattable ou repliable, appartenant à un conteneur 4 à embase 5 à structure plane et à pourtour carré ou rectangulaire.The Figures 1 to 4 represent a detachable locking device 1 in the upright position of a collapsible or collapsible upright 3 belonging to a container 4 with a base 5 with a flat structure and with a square or rectangular periphery.

Ce conteneur 4 est pourvu de quatre montants 3 assemblés de manière pivotante par leurs extrémités inférieures respectives avec ladite embase 5, chacun au niveau d'un coin de cette dernière, et peuvent être déplacés en pivotement entre une position redressée (figures 3 et 4) dans laquelle les montants sont sensiblement positionnés perpendiculairement au plan de l'embase et une position repliée ou rabattue le long d'un bord latéral de l'embase, dans laquelle ces montants sont inclinés en direction de l'embase ou disposés parallèlement à celle-ci, en reposant éventuellement sur ladite embase par leur extrémité libre (figure 1).This container 4 is provided with four uprights 3 pivotally assembled by their respective lower ends with said base 5, each at a corner thereof, and can be pivotally displaced between a rectified position ( figures 3 and 4 ) in which the uprights are substantially positioned perpendicularly to the plane of the base and a folded or folded position along a lateral edge of the base, wherein these uprights are inclined in the direction of the base or arranged parallel to that here, possibly resting on said base by their free end ( figure 1 ).

Ce dispositif de verrouillage 1 est constitué par deux moyens complémentaires 2 et 2' coopérant par engagement mutuel pour bloquer ou verrouiller automatiquement le montant 3 auquel il est associé, lorsqu'il est en position redressée. Un desdits moyens 2, 2' est solidaire dudit montant 3 et l'autre desdits moyens est solidaire de l'embase 5, le blocage ou verrouillage en position redressée pouvant être libéré par action sur l'un au moins desdits deux moyens 2 et 2'.This locking device 1 is constituted by two complementary means 2 and 2 'cooperating by mutual commitment to automatically block or lock the upright 3 with which it is associated, when in the rectified position. One of said means 2, 2 'is integral with said amount 3 and the other of said means is integral with the base 5, the locking or locking in the rectified position can be released by action on at least one of said two means 2 and 2 '.

Conformément à l'invention, chaque moyen complémentaire 2, 2' comporte au moins deux dents ou crans 6, 6' fournissant par coopération, en fonction de leur configuration d'engagement mutuel, au moins deux positions verrouillées ou bloquées en pivotement distinctes pour le montant 3 concerné, dont l'une correspond à sa position redressée et dont l'autre ou les autres correspond(ent) à une ou des position(s) proche(s) de cette position redressée, mais décalée(s) en direction de la position repliée de ce montant 3.According to the invention, each complementary means 2, 2 'comprises at least two teeth or notches 6, 6' cooperatively providing, according to their mutual engagement configuration, at least two distinct locked or locked pivot positions for the Amount 3 concerned, one of which corresponds to its adjusted position and the other (s) of which corresponds to a position (s) close to that adjusted position, but offset in the direction of the folded position of this amount 3.

Ainsi, les efforts de maintien du montant 3 considéré sont réparties sur au moins deux interfaces de contact entre dents ou crans 6 et 6', ces dernier(e)s pouvant présenter une taille plus faible (donc une structure plus massive et plus résistante) tout en garantissant un calage sûr et sans jeu à l'état verrouillé.Thus, the forces of maintaining the amount 3 considered are distributed over at least two contact interfaces between teeth or notches 6 and 6 ', the latter (s) may have a smaller size (therefore a more massive and more resistant structure) while guaranteeing safe and play-free locking in the locked state.

De plus, la présence sur chaque moyen 2, 2' d'au moins deux, préférentiellement de plusieurs, dents ou crans, permettent de définir au moins une (préférentiellement plusieurs) position(s) de verrouillage intermédiaires. Ces positions intermédiaires sécurisées peuvent éventuellement être occupées temporairement par le montant 3 considéré, par exemple après une première opération ou un premier mouvement de redressement, un mouvement supplémentaire de pivotement final pouvant amener ultérieurement ledit montant 3 dans sa position redressée, également verrouillée (position normale d'utilisation de gerbage).In addition, the presence on each means 2, 2 'of at least two, preferably several teeth or notches, to define at least one (preferably several) intermediate locking position (s).
