Un tel cadre est décrit par le document WO 2010/041023 A1 . La présente invention se rapporte plus particulièrement à un élément destiné à former tout ou partie d'un cadre assurant la protection d'articles ou de produits sensiblement plats lors de leur stockage et/ou leur transport.The present invention relates to a frame member for packaging flat articles, according to the preamble of claim 1, as well as the packaging obtained by the combination of such elements. Such a framework is described by the document WO 2010/041023 A1 . The present invention relates more particularly to an element intended to form all or part of a frame ensuring the protection of articles or substantially flat products during storage and / or transport.

On entend par article plat un produit dont l'épaisseur est notablement plus faible que ses autres dimensions.By flat article is meant a product whose thickness is significantly lower than its other dimensions.

Ces articles peuvent avoir une forme générale de parallélépipède, de cylindre, de polygone ou une forme quelconque et complexe.These articles may have a general shape of parallelepiped, cylinder, polygon or some form and complex.

Un tel élément de cadre trouve son application, notamment, dans le domaine de la logistique pour le conditionnement et la livraison de produits ou d'équipements plats et fragiles tels qu'en particulier, des écrans plats de téléviseurs, des panneaux de verre, des tableaux, ...Such a framework element finds its application, especially in the field of logistics for the packaging and delivery of products and flat and fragile equipment such as in particular, flat screens of televisions, glass panels, paintings, ...

En général, ces articles plats de grandes dimensions sont conditionnés dans des conteneurs tels que des caisses en bois ou en carton dans lesquelles ils sont immobilisés par des cales et protégés des chocs éventuels par des particules (granulés ou billes) de matériau alvéolaire (polystyrène), des fibres, associées, le cas échéant, à d'autres éléments d'emballage.In general, these large flat articles are packaged in containers such as wooden or cardboard boxes in which they are immobilized by wedges and protected from possible shocks by particles (granules or balls) of cellular material (polystyrene) fibers, associated, where appropriate, with other packaging elements.

Cependant, ces moyens de protection utilisent des volumes importants d'éléments disparates et de matières différentes dont tant l'acheminement jusqu'au lieu de conditionnement que la gestion ultérieure, après utilisation, pose des problèmes d'encombrement, de recyclage et donc de coûts.However, these means of protection use large volumes of disparate elements and different materials which both the routing to the packaging site and subsequent management after use, poses problems of congestion, recycling and therefore costs .

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante en proposant une solution permettant de garnir et de protéger l'épaisseur de ces articles plats de façon efficace et compacte.The present invention aims to solve these technical problems satisfactorily by proposing a solution for filling and protecting the thickness of these flat articles efficiently and compactly.

Ce but est atteint selon l'invention au moyen d'un élément de cadre pour le conditionnement d'articles plats selon la revendication 1.This object is achieved according to the invention by means of a frame element for packaging flat articles according to claim 1.

Ledits créneaux sont configurés et positionnés de telle sorte que deux éléments identiques se superposent de façon inversée et tête-bêche par emboîtement des premier et second profilés.The slot slots are configured and positioned so that two identical elements are invertedly overlapped and head-to-tail by interlocking the first and second profiles.

Selon une autre caractéristique, les créneaux de l'une des séries du premier profilé sont constitués d'une saillie intérieure à paroi droite prolongée extérieurement par un épaulement transversal.According to another characteristic, the crenellations of one of the series of the first profile consist of an inner projection with a straight wall extended externally by a transverse shoulder.

Selon une variante avantageuse, les créneaux de l'une des séries du second profilé sont séparés par des méplats extérieurs prolongés intérieurement par des dépouilles.According to an advantageous variant, the crenellations of one of the series of the second section are separated by external flats extended internally by bodies.

Selon une autre variante, les créneaux d'au moins l'une des séries du premier profilé sont pourvus d'alvéoles sous-jacentes d'amortissement des chocs.According to another variant, the slots of at least one of the series of the first profile are provided with underlying cells of damping shocks.

De préférence, le second profilé est pourvu d'une unique cavité longitudinale sous-jacente pour l'amortissement des chocs.Preferably, the second section is provided with a single underlying longitudinal cavity for damping shocks.

Selon un mode de réalisation spécifique, l'élément de cadre comprend plus de deux profilés articulés.According to a specific embodiment, the frame member comprises more than two articulated sections.

Selon une variante spécifique, lesdites butées sont formées de faces inclinées s'étendant à l'extrémité intérieure des premier et second profilés, de part et d'autre de la charnière.According to a specific variant, said stops are formed of inclined faces extending at the inner end of the first and second sections, on either side of the hinge.

Selon une autre variante, l'élément de cadre de l'invention comprend des organes de verrouillage des butées de contact.According to another variant, the frame element of the invention comprises locking members of the contact abutments.

Ces organes de verrouillage sont, de préférence, constitués d'un ergot porté par le second profilé et dont la face tournée vers le premier profilé vient en appui contre l'épaulement transversal extérieur du créneau immédiatement adjacent tandis que la saillie correspondante vient se loger dans la dépouille en vis à vis.These locking members are preferably constituted by a lug carried by the second profile and whose face facing the first profile abuts against the outer transverse shoulder of the immediately adjacent crenel while the corresponding projection is housed in the remains facing.

Selon encore un mode de réalisation particulier, lesdits créneaux sont réalisés sous forme de dents triangulaires.According to another particular embodiment, said crenellations are made in the form of triangular teeth.

Selon encore une autre variante destinée à faciliter le stockage et le transport des éléments de cadre, ladite charnière souple est conçue de façon à permettre un pliage des deux profilés selon un angle de 180° l'un par rapport à l'autre, au moins vers l'arrière.According to yet another variant intended to facilitate the storage and transport of the frame members, said flexible hinge is designed to allow folding of the two profiles at an angle of 180 ° with respect to each other, at least rearward.

Dans ce cas, les profils des faces inférieures des deux profilés sont complémentaires pour permettre leur emboîtement ou leur placage après repli de 180° vers l'arrière.In this case, the profiles of the lower faces of the two profiles are complementary to allow their interlocking or their plating after retracting 180 ° to the rear.

Un autre objet de l'invention est un emballage réalisé par l'association d'un ou plusieurs éléments de cadre précédemment décrits pour le conditionnement d'articles plats.Another object of the invention is a package made by the combination of one or more frame elements previously described for the packaging of flat articles.

L'élément de cadre de l'invention permet d'offrir un conditionnement ergonomique et économique pour des produits dont la forme plate et la fragilité rendent difficiles et délicates les opérations de manutention et de livraison par le fabricant, le transporteur, l'utilisateur ou le consommateur.The frame element of the invention makes it possible to offer ergonomic and economical packaging for products whose flat shape and fragility make the handling and delivery operations difficult and delicate for the manufacturer, the carrier, the user or the user. the consumer.

Chacun des profilés 1, 2 comporte une gorge axiale 10, 20 dans laquelle vient se loger le bord périphérique de l'article plat P (représenté sur la figure 4) à la manière d'un listeau.Each of the profiles 1, 2 has an axial groove 10, 20 in which is housed the peripheral edge of the flat article P (shown in FIG. figure 4 ) in the manner of a strip.

L'élément de cadre est réalisé, de préférence, avec un matériau alvéolaire déformable (type polystyrène expansé) ce qui permet d'engager le bord de l'article plat en force dans la gorge 10, 20 et d'assurer, par coincement, une bonne tenue mécanique de l'assemblage.The frame element is preferably made of a deformable cellular material (expanded polystyrene type) which makes it possible to engage the edge of the flat article in force. in the groove 10, 20 and ensure, by wedging, a good mechanical strength of the assembly.

Une relative élasticité du matériau peut renforcer le serrage dans la gorge et le placage des profilés 1, 2 sur les faces planes périphériques de l'article P.A relative elasticity of the material can reinforce the clamping in the groove and the plating of the profiles 1, 2 on the peripheral flat faces of the article P.

Cette gorge est délimitée latéralement et sur chaque profilé, par des flancs constitués de deux séries parallèles de créneaux 11, 12, 21, 22.This groove is delimited laterally and on each profile, by flanks consisting of two parallel series of crenellations 11, 12, 21, 22.

Dans le mode de réalisation représentée sur les figures 1 et 2, les créneaux sont réalisés sous forme de dents sensiblement triangulaires.In the embodiment shown on the figures 1 and 2 the crenellations are made in the form of substantially triangular teeth.

Toutefois, l'invention n'exclut pas des profils différents de ces créneaux à condition qu'ils permettent toujours la superposition de plusieurs éléments dans les conditions mentionnées ci-après.However, the invention does not exclude different profiles of these slots provided that they still allow the superposition of several elements under the conditions mentioned below.

De même, selon une variante non représentée, au moins l'un des profilés pourraient présenter une courbure en vue de monter l'élément sur tout ou partie d'un article dont les bords ne seraient pas rectilignes.Similarly, according to a variant not shown, at least one of the profiles could have a curvature to mount the element on all or part of an article whose edges would not be straight.

Les créneaux respectifs 12a, 22a des deux profilés 1, 2 qui sont adjacents à la charnière 3 sont pourvus de butées de contact associées à des organes de verrouillage qui seront détaillés ci-après.The respective slots 12a, 22a of the two sections 1, 2 which are adjacent to the hinge 3 are provided with contact stops associated with locking members which will be detailed below.

Ces butées assurent le blocage des deux profilés dans une position où ils s'étendent ici de façon perpendiculaire l'un par rapport à l'autre en formant localement une cornière, comme représenté sur la figure 2.These stops ensure the locking of the two sections in a position where they extend perpendicularly to one another by locally forming an angle, as shown in FIG. figure 2 .

Il est, toutefois, possible de prévoir que ces butées assurent un blocage selon une orientation angulaire différente de 90°, adaptée aux contours et au profil spécifiques de l'article plat à conditionner.It is, however, possible to provide that these stops provide locking in an angular orientation different from 90 °, adapted to the specific contours and profile of the flat article to be packaged.

Dans cette position qui correspond à l'utilisation de l'élément de l'invention, les gorges 10, 20 respectives des profilés 1, 2 sont raccordées et sont ouvertes en mâchoire vers l'intérieur de l'angle et en regard mutuel pour recevoir les coins et les bords de l'article plat P, à la manière d'un encadrement.In this position which corresponds to the use of the element of the invention, the respective grooves 10, 20 of the profiles 1, 2 are connected and are open in jaw towards the inside of the angle and facing each other to receive the corners and edges of the flat article P, in the manner of a frame.

La charnière 3 étant fermée, elle vient se positionner dans les coins de l'article plat, comme représenté sur la figure 4.The hinge 3 is closed, it is positioned in the corners of the flat article, as shown on the figure 4 .

De manière plus générale, il est aussi possible de fixer l'élément de cadre de l'invention le long d'un bord droit de l'article plat P sans replier la charnière 3 à la manière d'une bordure, sans qu'il soit nécessaire de verrouiller les deux profilés dans leur position respective.More generally, it is also possible to fix the frame element of the invention along a straight edge of the flat article P without folding the hinge 3 in the manner of a border, without it. it is necessary to lock the two sections in their respective positions.

La charnière souple 3 est d'un type connu en soi et est constituée d'une zone amincie de la matière constitutive de l'élément située, de préférence, en position médiane entre les profilés 1, 2. Cette charnière autorise le pliage élastique des deux profilés l'un par rapport à l'autre.The flexible hinge 3 is of a type known per se and consists of a thinned area of the constituent material of the element preferably located in the median position between the profiles 1, 2. This hinge allows the elastic folding of the two profiles relative to each other.

Les créneaux 11, 12, 21, 22 sont configurés et positionnés de telle sorte que deux éléments identiques peuvent se superposer de façon inversée et tête-bêche par co-emboîtement des premier et second profilés, comme représenté sur les figures 3A, 3B.The crenellations 11, 12, 21, 22 are configured and positioned so that two identical elements can be superposed in an inverted manner and head-to-tail by co-fitting of the first and second profiles, as shown in FIGS. Figures 3A , 3B .

Les créneaux 12 de l'une des deux séries du premier profilé 1 sont constitués d'une saillie intérieure 121 à paroi droite prolongée extérieurement par un épaulement transversal 122 (figures 1, 2, 5A et 5B), tandis que les créneaux 22 de l'une des séries du second profilé 2 sont séparés par des méplats extérieurs 222 prolongés intérieurement par des dépouilles 221.The crenellations 12 of one of the two series of the first profile 1 consist of an inner projection 121 with a straight wall extended externally by a transverse shoulder 122 ( figures 1 , 2 , 5A and 5B ), while the crenellations 22 of one of the series of the second section 2 are separated by outer flats 222 extended internally by bodies 221.

Les créneaux 11, 21 des autres séries des deux profilés 1, 2 sont identiques comme cela est visible sur la figure 2.The crenellations 11, 21 of the other series of the two sections 1, 2 are identical as is visible on the figure 2 .

Le profil de la dépouille 221 du second profilé 2 est adapté pour recevoir, par emboîtement, la saillie 121 du créneau 12 en vis à vis du premier profilé 1 lors de l'empilage de deux éléments, comme représenté sur les figures 3A, 3B.The profile of the flange 221 of the second section 2 is adapted to receive, by interlocking, the projection 121 of the crenel 12 facing the first profile 1 during the stacking of two elements, as shown in FIGS. Figures 3A , 3B .

A cet effet, les saillies 121 et les dépouilles 221 sont réalisées sur le même côté de l'élément, comme cela apparaît sur la figure 2.For this purpose, the protrusions 121 and the struts 221 are made on the same side of the element, as shown in FIG. figure 2 .

Conjointement, les épaulements 122 du premier profilé 1 viennent en appui contre les méplats 222 du second profilé 2.Together, the shoulders 122 of the first section 1 bear against the flats 222 of the second section 2.

Un tel empilage est très compacte et offre un encombrement très réduit.Such a stack is very compact and offers a very small footprint.

Un autre mode de stockage optimal des éléments de cadre sera décrit par la suite.Another optimal storage mode of the frame elements will be described later.

Les butées sont formées de faces inclinées 13, 23 s'étendant à l'extrémité intérieure respectivement des premier et second profilés 1, 2, de part et d'autre de la charnière 3.The stops are formed of inclined faces 13, 23 extending at the inner end respectively of the first and second sections 1, 2, on either side of the hinge 3.

Ces faces inclinées sont destinées à venir en appui mutuel lors de la fermeture de la charnière, comme représenté sur la figure 2.These inclined faces are intended to come into mutual support when closing the hinge, as shown on the figure 2 .

Plus précisément, dans le mode de réalisation représenté, la gorge 20 du second profilé 2 est située à un niveau supérieur à celui de la gorge 10 du premier profilé 1, comme représenté sur la figure 1.More specifically, in the embodiment shown, the groove 20 of the second section 2 is located at a level greater than that of the groove 10 of the first section 1, as shown in FIG. figure 1 .

Dans cette configuration, les faces inclinées 13 des créneaux 11, 12a du premier profilé 1 viennent en contact avec la face inclinée 23 du second profilé 2 dont la surface est plus grande.In this configuration, the inclined faces 13 of the crenellations 11, 12a of the first section 1 come into contact with the inclined face 23 of the second profile 2 whose surface is larger.

Les organes de verrouillage sont, quant à eux, constitués ici d'un ergot porté par le créneau 22a du second profilé 2 et dont la face 23a, tournée vers le premier profilé 1, vient en appui contre l'épaulement transversal extérieur 122a du créneau 12a immédiatement adjacent tandis que la saillie correspondante 121 vient se loger dans la dépouille 221 en vis à vis, comme représenté sur la figure 2.The locking members are, in turn, constituted by a lug carried by the crenel 22a of the second section 2 and whose face 23a, facing the first section 1, bears against the outer transverse shoulder 122a of the crenel 12a immediately adjacent while the corresponding projection 121 is housed in the recess 221 facing, as shown in the figure 2 .

Les créneaux d'au moins l'une des séries (et ici les créneaux 12) du profilé 1 sont pourvus d'alvéoles 14 sous-jacentes assurant l'amortissement des chocs.The slots of at least one of the series (and here the crenellations 12) of the section 1 are provided with cells 14 underlying providing damping shocks.

Le second profilé 2 est pourvu, quant à lui, d'une unique cavité 24 sous-jacente longitudinale d'amortissement des chocs.The second section 2 is provided, meanwhile, a single cavity 24 underlying longitudinal damping shocks.

Dans le mode de réalisation représenté, notamment sur la figure 2, les alvéoles 14 et la cavité 24 sont réalisées du même côté des deux profilés 1, 2 mais il est possible de les positionner, en fonction des besoins, sur deux côtés opposés.In the embodiment shown, in particular on the figure 2 , the cells 14 and the cavity 24 are made of same side of both profiles 1, 2 but it is possible to position them, as needed, on two opposite sides.

Les alvéoles 14 et la cavité 24 forment ainsi des zones évidées d'absorption de l'énergie cinétique qui est susceptible d'être communiquée de façon incidente au colis lors d'impacts (chute, chocs,...), en préservant ainsi l'intégrité de l'article.The cells 14 and the cavity 24 thus form recessed areas of absorption of the kinetic energy that is likely to be communicated incidentally to the package during impacts (drop, shock, ...), thus preserving the integrity of the article.

La cavité longitudinale 24 peut, le cas échéant, servir de compartiment ergonomique permettant d'accueillir des accessoires de l'article à conditionner.The longitudinal cavity 24 may, where appropriate, serve as an ergonomic compartment for receiving accessories of the article to be packaged.

Selon une variante non représentée, l'élément comprend plus de deux profilés.According to a variant not shown, the element comprises more than two profiles.

Les profilés sont alors articulés les uns aux autres à la manière d'une chaîne de vélo et viennent garnir au plus près et en l'enserrant, le pourtour de l'article P.The profiles are then articulated to each other in the manner of a bicycle chain and come close to garnish and surrounding, the perimeter of the article P.

Le second profilé 2 a vocation à être monté sur la partie basse de l'article plat P de façon à offrir un piètement au colis ainsi formé, comme représenté sur la figure 4.The second section 2 is intended to be mounted on the lower part of the flat article P so as to provide a base for the package thus formed, as shown in FIG. figure 4 .

A cet effet, les parois d'extrémité de la cavité longitudinale 24 sont avantageusement orientées en arc-boutement et, le cas échéant, renforcées en vue d'assurer une meilleure stabilité.For this purpose, the end walls of the longitudinal cavity 24 are advantageously oriented in abutment and, where appropriate, reinforced to ensure better stability.

Dans la variante illustrée par les figures 7A et ne faisant pas partie de l'invention, les profilés 1, 2 ont été représentés sous forme simplifiée.In the variant illustrated by the Figures 7A and not forming part of the invention, the profiles 1, 2 have been shown in simplified form.

Dans cette variante, la charnière souple 3 est plus particulièrement adaptée et destinée à permettre un pliage élastique dans les deux sens.In this variant, the flexible hinge 3 is more particularly adapted and intended to allow elastic folding in both directions.

Le pliage des deux profilés l'un vers l'autre dans le sens de la fermeture a déjà été décrit en référence aux figures 1 à 6.The folding of the two sections towards each other in the direction of closure has already been described with reference to Figures 1 to 6 .

Les figures 7A et 7B illustrent, quant à elles, le pliage des deux profilés vers l'arrière (sens d'ouverture représenté sur la figure 7A par la flèche) selon un angle de 180° l'un par rapport à l'autre.The Figures 7A and 7B illustrate, for their part, the folding of the two profiles towards the rear (opening direction shown in FIG. Figure 7A arrow) at an angle of 180 ° to each other.

L'amplitude de 180° n'était pas nécessaire pour un pliage de fermeture tel que décrit précédemment dont le but était d'assurer la protection des angles d'un article plat. D'ailleurs, la présence des créneaux pourrait faire obstacle à un pliage de fermeture à 180°, à moins que ceux-ci ne soient spécifiquement adaptés à un tel pliage.The amplitude of 180 ° was not necessary for a folding closure as described above whose purpose was to ensure the protection of the corners of a flat article. Moreover, the presence of the slots could hinder a folding closure 180 °, unless they are specifically adapted to such folding.

Dans cette autre variante, le pliage est plus particulièrement destiné à faciliter le conditionnement et le transport des éléments de cadre eux-mêmes.In this other variant, the folding is more particularly intended to facilitate the packaging and transport of the frame elements themselves.

En effet, dans un objectif de réduire l'encombrement des éléments de cadre pour leur stockage, leur acheminement puis la livraison sur leur lieu d'utilisation, il est avantageux de replier les deux profilés l'un contre l'autre comme représenté sur la figure 7B.Indeed, in order to reduce the bulk of the frame elements for storage, routing and delivery to their place of use, it is advantageous to fold the two profiles against each other as shown on the Figure 7B .

Dans ce cas, les faces extérieures ou dos 15, 25 des deux profilés 1, 2 seront planes (figures 7A, 7B) ou bien leurs profils seront complémentaires pour permettre leur emboîtement ou leur placage dos à dos après rabat de 180° vers l'arrière.In this case, the outer or back faces 15, 25 of the two sections 1, 2 will be flat ( Figures 7A, 7B ) or their profiles will be complementary to allow their nesting or plating back to back after flap 180 ° backwards.
