Description
L'invention a pour objet un dispositif de protection et/ou de maintien d'objet en polystyrène expansé ou en un matériau d'un type analogue constitué par l'assemblage d'au moins deux éléments ayant chacun une partie conformée suivant un peigne dont les dents sont munies de moyens qui permettent la réunion des deux dits éléments entre eux par simple rapprochement et emboîtement d'une partie en peigne d'un élément dans la partie en peigne de l'autre élément.The subject of the invention is a device for protecting and / or maintaining an object in expanded polystyrene or in a material of a similar type consisting of the assembly of at least two elements each having a part shaped according to a comb, the teeth are provided with means which allow the two said elements to be joined together by simple bringing together and interlocking of a comb part of an element in the comb part of the other element.
On utilise déjà, de longue date, des profilés de polystyrène expansé pour maintenir et/ou protéger à l'encontre des chocs des objets fragiles, qu'il s'agisse d'appareils, de pièces de machines, ou encore de meubles ou parties constitutives de meubles. Quel que soit le domaine d'application, mais en particulier dans celui de l'industrie du meuble, les profilés de protection et/ou de maintien à base de polystyrène expansé sont fréquemment conformés suivant des gouttières, à section droite en U, enfermées dans un suremballage en film de matière plastique thermo-rétractable. Ces profilés doivent être réalisés suivant des largeurs et des longueurs variables adaptées à chacun des meubles ou produits à protéger et le fabricant de gouttières doit alors réaliser ou prévoir autant de moules de fabrication que d'éléments ayant des cotes différentes ce qui, bien entendu, est d'un coût important d'une part, exige des aires de stockage et d'entretien également importantes, d'autre part et, en outre, ne peut pas être mis en oeuvre pour la protection ou l'emballage de petites séries d'objets pour lesquels le prix de la fabrication de l'outillage ne serait pas amorti.Profiles of expanded polystyrene have already been used for a long time to maintain and / or protect against impact shock fragile objects, be they appliances, machine parts, or even furniture or parts constituting furniture. Whatever the field of application, but in particular in that of the furniture industry, the protection and / or support profiles based on expanded polystyrene are frequently shaped according to gutters, with a U-shaped cross section, enclosed in an overwrapping in heat-shrinkable plastic film. These profiles must be produced according to variable widths and lengths adapted to each of the pieces of furniture or products to be protected and the gutter manufacturer must then produce or provide as many manufacturing molds as there are elements having different dimensions, which, of course, is of high cost on the one hand, requires equally large storage and maintenance areas, on the other hand and, moreover, cannot be used for the protection or packaging of small series d 'objects for which the price of manufacturing the tools would not be amortized.
On a déjà également proposé,dans FR-A-2 609 695, un dispositif comprenant au moins deux paires de barreaux complémentaires en forme de cornières, disposés l'un au-dessus de l'autre pour former un élément de protection de section en U susceptible d'être emboîté sur l'un des bords du ou des objets à emballer, ces deux barreaux étant assemblés du fait de l'imbrication de dents saillantes complémentaires prévues sur l'un et l'autre de ceux-ci, et étant pourvus, à leurs extrémités, de languettes de retenue susceptibles d'être éventuellement éliminées. Avec un tel dispositif, un mouvement d'écartement des barreaux dans la direction longitudinale supprime l'assemblage relatif, de sorte qu'existe le risque de voir se défaire le dispositif de protection en cas de manipulation défectueuse après qu'il a été mis en place sur un objet à protéger mais avant que l'assemblage ait été introduit dans une boîte en carton ou après qu'il en a été extrait.FR-A-2 609 695 has also already proposed a device comprising at least two pairs of complementary bars in the form of angles, arranged one above the other to form a cross-section protection element. U can be fitted on one of the edges of the object or objects to be packaged, these two bars being assembled due to the overlapping of complementary projecting teeth provided on one and the other of these, and being provided, at their ends, with retaining tabs capable of 'be eventually eliminated. With such a device, a movement of the bars apart in the longitudinal direction eliminates the relative assembly, so that there is the risk of the protective device coming apart in the event of faulty handling after it has been put in place. place on an object to be protected but before the assembly has been introduced into a cardboard box or after it has been extracted from it.
C'est, par conséquent, un but général de l'invention de fournir des moyens permettant de pallier l'inconvénient rapporté ci-dessus des dispositifs connus de protection et/ou de maintien d'objets en polystyrène expansé.It is therefore a general aim of the invention to provide means making it possible to overcome the drawback reported above of known devices for protecting and / or maintaining objects made of expanded polystyrene.
Un dispositif de protection et/ou de maintien d'objet en polystyrène expansé ou en un matériau analogue constitué par l'assemblage d'au moins deux éléments ayant chacun une partie conformée suivant un peigne dont les dents sont munie de moyens qui permettent la réunion et le maintien entre eux des deux dits éléments par simple rapprochement et emboîtement d'une partie en peigne d'un élément dans la partie en peigne de l'autre est caractérisé, selon l'invention, en ce que pour le maintien des deux dits éléments entre eux à l'encontre d'une séparation éventuelle par déplacement dans une direction opposée à celle ayant provoqué leur réunion l'assemblage fait application de reliefs ménagés, de fabrication même lors du moulage ou par façonnage ultérieur, sur les faces latérales des dents de peigne qui sont transversales à la direction longitudinale de l'élément et qui sont destinées à coopérer entre elles de deux éléments adjacents.A device for protecting and / or holding an object in expanded polystyrene or in a similar material constituted by the assembly of at least two elements each having a shaped part according to a comb, the teeth of which are provided with means which allow the meeting and the maintenance between them of the two said elements by simple bringing together and interlocking of a comb part of an element in the comb part of the other is characterized, according to the invention, in that for the maintenance of the said two elements between them against a possible separation by displacement in a direction opposite to that which caused their meeting the assembly makes use of reliefs, of manufacture even during molding or by subsequent shaping, on the lateral faces of the teeth comb which are transverse to the longitudinal direction of the element and which are intended to cooperate with each other of two adjacent elements.
Dans un mode d'exécution de cette réalisation, les reliefs sont des ondulations dont le pas est choisi pour permettre l'obtention d'un dispositif de protection et/ou de maintien adapté à la plupart des objets avec lesquels il doit coopérer.In one embodiment of this embodiment, the reliefs are undulations whose pitch is chosen to allow obtaining a protection and / or holding device suitable for most of the objects with which it must cooperate.
Dans un autre mode d'exécution, les reliefs sont des stries dont la section droite est quelque peu en lame de scie ou en "arête de poisson".In another embodiment, the reliefs are streaks whose cross section is somewhat in the shape of a saw blade or "fishbone".
Le pas des dents de peigne de chaque élément est choisi en fonction des desiderata de la pratique et, en tout état de cause, de manière à permettre à la fois l'assemblage des objets de petite largeur d'une part et, d'autre part, garantir la rigidité souhaitée du dispositif.The pitch of the comb teeth of each element is chosen according to the wishes of the practice and, in any event, so as to allow both the assembly of objects of small width on the one hand and, on the other hand, guarantee the desired rigidity of the device.
Dans une autre forme de réalisation, l'assemblage fait application de l'élasticité du matériau qui les constitue et de la forme même des dents qui, vues en plan, présentent une légère contre-dépouille sur chacune de leurs faces destinées à coopérer avec les faces conjuguées d'un élément adjacent.In another embodiment, the assembly applies the elasticity of the material which constitutes them and the very shape of the teeth which, seen in plan, have a slight undercut on each of their faces intended to cooperate with the conjugate faces of an adjacent element.
Dans une forme de réalisation préférée, chaque élément a sensiblement la forme d'une cornière, à section droite en L, dont l'une des branches présente les dents d'assemblage à l'autre cornière et dont l'autre branche est pleine, le dispositif ayant ainsi, après réunion des éléments entre eux, sensiblement une forme de gouttière à section droite en U.In a preferred embodiment, each element has substantially the shape of an angle iron, with an L-shaped cross section, one of the branches of which has the assembly teeth to the other angle and of which the other branch is full, the device thus having, after joining the elements together, substantially a shape of gutter with U-shaped cross section.
De bons résultats ont été obtenus avec des éléments d'une longueur unitaire d'environ 1200 mm, d'une épaisseur de 25 mm et avec des dents et des espaces interdentaires d'une larguer de 40 à 60 mm.Good results have been obtained with elements with a unit length of approximately 1200 mm, a thickness of 25 mm and with teeth and interdental spaces of a width of 40 to 60 mm.

On se réfère d'abord aux figures 1 à 3 qui illustrent un dispositif 10 en polystyrène expansé ou en un matériau analogue pour le maintien et/ou la protection d'objets, notamment à l'encontre des chocs et qui, dans la forme de réalisation décrite et représentée, est une gouttière à ailes 11 et 12 réunies par une âme transversale 13 conférant à l'ensemble une section droite en U qui coiffe la tranche T de l'objet O à maintenir ou protéger.Reference is first made to FIGS. 1 to 3 which illustrate a
Conformément à l'invention, le dispositif 10 résulte de l'assemblage entre eux d'au moins deux éléments e₁ et e₂ en forme générale de cornière, à section droite en L, dont une branche 11, 12 est pleine et dont l'autre est conformée suivant un peigne dont les dents sont référencées 15₁, 15₂, 15₃,...etc pour l'élément e₁ et 16₁, 16₂, 16₃,...etc pour l'élément e₂, respectivement, les dents 15 et 16 étant munies de moyens qui permettent le maintien après assemblage entre eux des éléments comme e₁ et e₂ par simple rapprochement et emboîtement des dents de l'un des éléments dans les intervalles inter-dentaires de l'autre élément, comme bien visible sur les figures 2 et 3, l'emboîtement étant facilité par les chanfreins ménagés aux extrémités libres des dents.According to the invention, the
Dans une première réalisation, les dents 15 et 16 des éléments e₁ et e₂, respectivement, sont munies sur leurs faces transversales à la direction longitudinale des éléments, comme montrées en 17 et 18 pour l'élément e₁ et en 19 et 20 pour l'élément e₂, de reliefs obtenus lors de la fabrication même par moulage des éléments ou, en variante, par façonnage après moulage.In a first embodiment, the teeth 15 and 16 of the elements e₁ and e₂, respectively, are provided on their faces transverse to the longitudinal direction of the elements, as shown in 17 and 18 for the element e₁ and in 19 and 20 for the element e₂, reliefs obtained during the manufacturing itself by molding the elements or, alternatively, by shaping after molding.
Dans un premier mode d'exécution, les reliefs forment, sur les faces comme 17, 18, 19 et 20 des dents des éléments, des stries régnant sur toute la hauteur h des dents et dont la section droite est quelque peu en lame de scie ou en arête de poisson, comme bien montré sur la figure 4 où l'on a marqué par p le pas des stries et par d leur profondeur.In a first embodiment, the reliefs form, on the faces like 17, 18, 19 and 20 of the teeth of the elements, streaks prevailing over the entire height h of the teeth and the cross section of which is somewhat like a saw blade or fishbone, as well shown in Figure 4 where we marked by p the streak pitch and by d their depth.
Dans le mode d'exécution montré sur la figure 5, les dents 15, 16 de chaque élément e₁ et e₂ présentent sur leurs faces transversales à la direction longitudinale de l'élément des ondulations régulières dont le pas est également marqué en p et la profondeur en d.In the embodiment shown in FIG. 5, the teeth 15, 16 of each element e₁ and e₂ have on their faces transverse to the longitudinal direction of the element regular undulations whose pitch is also marked in p and the depth in d .
Dans la réalisation montrée sur la figure 6, les dents 15, 16 de chaque élément e₁ et e₂ présentent sur chacune de leur face transversale à la direction longitudinale une légère contre-dépouille illustrée schématiquement sur la figure par l'angle α existant entre la face transversale de la dent et la normale à la direction longitudinale des éléments, lesquels sont assemblés en tirant parti de l'élasticité du matériau qui les constitue.In the embodiment shown in FIG. 6, the teeth 15, 16 of each element e₁ and e₂ have on each of their faces transverse to the longitudinal direction a slight undercut illustrated schematically in the figure by the angle α existing between the face transverse of the tooth and normal to the longitudinal direction of the elements, which are assembled by taking advantage of the elasticity of the material which constitutes them.
Quels que soient les moyens mis en oeuvre pour l'assemblage entre eux des éléments e₁ et e₂, on comprend aisément que la largeur de l'âme 13 du dispositif en U peut être réglée pour obtenir un profil propre à être associé à chaque objet O en fonction de l'épaisseur i de celui-ci, simplement en emboîtant plus ou moins totalement ou profondément les dents d'un élément dans les intervalles inter-dentaires de l'autre.Whatever the means used for the assembly between them of the elements e entre and e₂, it is easily understood that the width of the
Bien que l'invention ait été décrite en référence à un dispositif de maintien et/ou de protection à section droite en U, on comprend qu'elle peut être mise en oeuvre pour la fabrication de toute autre forme de dispositif par exemple des "coins" obtenus par assemblage de deux éléments à peignes en forme d'équerres.Although the invention has been described with reference to a holding and / or protection device with a U-shaped cross section, it is understood that it can be implemented for the manufacture of any other form of device for example "corners" obtained by assembling two elements with combs in the form of squares.
Dans le cas de gouttières, de bons résultats ont été obtenus avec des éléments en polystyrène expansé d'une densité de 28 g/l moulés en éléments unitaires de cornières en L d'une longueur de 1200 mm, d'une épaisseur de 25 mm, d'un pas de dents l de 40 à 60 mm et d'une épaisseur d'ailes de 10 mm. Dans de tels éléments, le pas p a été choisi égal à 5 mm, la profondeur d dans le cas de stries en arêtes de poisson ayant une valeur de 2,5 mm (figure 4) tandis que pour un même pas de 5 mm, la profondeur d dans le cas des ondulations n'était que de 1,5 mm (figure 5).In the case of gutters, good results have been obtained with elements in expanded polystyrene with a density of 28 g / l molded into unitary elements of L-shaped angles with a length of 1200 mm, a thickness of 25 mm. , a tooth pitch l from 40 to 60 mm and a wing thickness of 10 mm. In such elements, the pitch p has been chosen equal to 5 mm, the depth d in the case of fishbone streaks having a value of 2.5 mm (FIG. 4) while for the same pitch of 5 mm, the depth d in the case of the corrugations was only 1.5 mm (Figure 5).
De tels éléments, assemblés tête-bêche et décalés, par exemple, de 600 mm, puis tronçonnés, permettent ainsi la réalisation d'éléments de longueur souhaitée, en fonction des desiderata de la pratique et dont l'ouverture correspondant à la dimension i des objets à protéger et/ou maintenir peut varier par pas de 5 mm, de 35 à 50 mm, puis de 55 à 90 mm, puis de 95 à 165 mm.Such elements, assembled head to tail and offset, for example, by 600 mm, then sectioned, thus allow the production of elements of desired length, according to the wishes of the practice and whose opening corresponding to the dimension i of objects to be protected and / or maintained can vary in steps of 5 mm, from 35 to 50 mm, then from 55 to 90 mm, then from 95 to 165 mm.
Pour de grandes longueurs de dispositifs, l'invention fait application de plus de deux éléments, par exemple d'éléments supplémentaires comme l'élément e₃, figure 2, relié à l'élément e₂ par un tenon comme 25 régnant sur l'aile 12 et une partie d'une dent.For large lengths of devices, the invention makes use of more than two elements, for example additional elements such as the element e₃, FIG. 2, connected to the element e₂ by a pin like 25 prevailing on the
