Description

L'invention propose un dispositif d'emballage pour au moins deux balais d'essuyage notamment pour véhicule automobile.The invention proposes a packaging device for at least two wiper blades, in particular for a motor vehicle.

L'invention concerne également un ensemble comportant un dispositif d'emballage et les balais reçus dans ce dispositif d'emballage.The invention also relates to an assembly comprising a packaging device and the brushes received in this packaging device.

L'invention propose plus particulièrement un dispositif d'emballage destiné à recevoir au moins deux balais d'essuyage dont chacun comporte une lame inférieure d'essuyage, et au moins un élément de structure d'orientation principale longitudinale qui est déformable élastiquement et qui est cintré selon un plan longitudinal médian du balai. Ce dispositif d'emballage comporte au moins une coque inférieure qui délimite plusieurs logements d'orientation principale longitudinale ouverts vers le haut, dans chacun desquels l'un desdits au moins deux balais peut être reçu en position rangée, de manière telle que, pour chaque balai, le plan longitudinal médian du balai puisse délimiter avec un plan longitudinal vertical orthogonal à la face supérieure ouverte du logement, un angle aigu.The invention more particularly proposes a packaging device intended to receive at least two wiping brushes, each of which comprises a lower wiper blade, and at least one longitudinal main structure component which is elastically deformable and which is bent along a median longitudinal plane of the broom. This packaging device comprises at least one lower shell which delimits a plurality of upwardly-facing longitudinal principal orientation recesses, in each of which one of said at least two brushes can be received in a stowed position, so that for each broom, the median longitudinal plane of the broom may delimit with a vertical longitudinal plane orthogonal to the open upper face of the housing, an acute angle.

Le document US-A-2006/0163096 décrit un ensemble comportant deux balais pour lequel la coque inférieure du dispositif d'emballage délimite un logement associé à chaque balai et dans lequel le balai associé est reçu avec son plan longitudinal médian orienté globalement verticalement.The document US-2006/0163096 discloses an assembly comprising two brushes for which the lower shell of the packaging device defines a housing associated with each blade and wherein the associated blade is received with its median longitudinal plane oriented globally vertically.

Le dispositif d'emballage comporte aussi un étui externe dans lequel la coque et les balais sont reçus.The packaging device also includes an outer case in which the shell and the brooms are received.

La coque inférieure est relativement souple et ne permet pas le maintien des balais en position rangée dans les logements. L'étui est lui relativement rigide, de manière que les balais et la coque sont maintenus redressés verticalement par l'étui.The lower shell is relatively flexible and does not allow the maintenance of the brushes in stored position in the housing. The case is relatively rigid, so that the brushes and the shell are held upright by the holster.

Ce dispositif d'emballage permet ainsi de redresser simultanément les deux balais lors de leur introduction simultanément avec la coque inférieure.This packaging device thus makes it possible to simultaneously straighten both brushes during their introduction simultaneously with the lower shell.

Cependant, puisque la coque inférieure, logeant les deux balais, est souple, la manipulation de la coque est alors relativement difficile pour un opérateur, lors de l'assemblage des balais avec la coque inférieure, et pour la manipulation de la coque inférieure avec les balais.However, since the lower shell, housing the two brushes, is flexible, the handling of the shell is then relatively difficult for an operator, when assembling the brushes with the lower shell, and for the handling of the lower shell with the broom.

De plus, le dispositif d'emballage comporte des composants réalisés à partir de matériaux différents, ce qui rend sa fabrication relativement complexe et son recyclage difficile.In addition, the packaging device comprises components made from different materials, which makes its relatively complex manufacturing and recycling difficult.

Les documents DE 10 2004 013508 A1 et EP-A-1 842 788 montrent deux autres dispositifs d'emballage pour balais d'essuyage.The documents DE 10 2004 013508 A1 and EP-A-1,842,788 show two other packaging devices for wiper blades.

Pour la description de l'invention, on adoptera à titre non limitatif les orientations verticale, longitudinale et transversale selon le repère V, L, T indiqué aux figures.For the description of the invention, the vertical, longitudinal and transverse orientations according to the reference V, L, T indicated in the figures will be adopted without limitation.

Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the following description, identical, similar or similar elements will be designated by the same reference numerals.

On a représenté à la figure 1 un ensemble comportant plusieurs balais 12 d'essuie-glace, ici deux balais 12 et un dispositif d'emballage 10 des balais 12, dans lequel les deux balais sont reçus.We have shown figure 1 an assembly comprising a plurality of wiper blades 12, here two brushes 12 and a packaging device 10 of the brushes 12, in which the two brushes are received.

Comme on peut le voir aux figures 2 à 4, chaque balai 12 est un balai de faible hauteur communément appelé balai "flat blade", qui comporte un élément de structure 14 d'orientation principale longitudinale, qui porte les autres composants du balai 12.As can be seen at Figures 2 to 4 each broom 12 is a low-profile broom, commonly referred to as a "flat blade" broom, which has a frame element 14 for orientation main longitudinal, which carries the other components of the broom 12.

Selon le mode de réalisation représenté aux figures 2 à 4, l'élément de structure 14 de chaque balai 12 porte deux vertèbres 16, une lame inférieure 18 d'essuyage du panneau vitré, deux embouts terminaux aux extrémités 12a du balai 12 et un connecteur 20 supérieur de montage et d'articulation du balai 12 à l'extrémité d'un bras d'entraînement (non représenté) du balai 12 en mouvement de balayage.According to the embodiment shown in Figures 2 to 4 , the structural element 14 of each blade 12 carries two vertebrae 16, a lower blade 18 for wiping the glass panel, two end caps at the ends 12a of the blade 12 and an upper connector 20 for mounting and hinging the blade 12 at the end of a drive arm (not shown) of the blade 12 in scanning motion.

L'élément de structure 14 et les vertèbres 16 forment la structure du balai 12 proprement dit, les vertèbres sont cintrées dans le plan longitudinal médian (PLM) du balai 12, et elles sont déformables élastiquement. Ainsi, lorsque le balai 12 est en appui sur un panneau vitré, les efforts d'appui sont répartis sur toute la longueur de la lame 18.The structural element 14 and the vertebrae 16 form the structure of the blade 12 itself, the vertebrae are bent in the median longitudinal plane (PLM) of the blade 12, and they are elastically deformable. Thus, when the blade 12 bears against a glazed panel, the support forces are distributed over the entire length of the blade 18.

L'élément de structure 14 comporte en outre une nervure supérieure 22, appelé aussi déflecteur, qui est profilée aérodynamiquement, pour améliorer la pression de la lame 18 sur le panneau vitré, lors du déplacement du véhicule.The structural element 14 further comprises an upper rib 22, also called deflector, which is aerodynamically profiled, to improve the pressure of the blade 18 on the glass panel, during the movement of the vehicle.

Selon un autre mode de réalisation des balais 12 qui sera décrit en relation à la figure 7, l'élément de structure 14 délimite un logement tubulaire dans lequel une vertèbre 16 est reçue, et intègre une partie formant déflecteur aérodynamique.According to another embodiment of the brushes 12 which will be described in relation to the figure 7 , the structural element 14 delimits a tubular housing in which a vertebra 16 is received, and integrates an aerodynamic deflector portion.

Il sera compris que l'invention ne se limite pas à ces deux seuls modes de réalisation des balais 12, et qu'elle concerne plus généralement les balais dont l'élément de structure est cintré selon le plan longitudinal médian du balai, et est déformable élastiquement.It will be understood that the invention is not limited to these two only embodiments of the brushes 12, and more generally relates to the brushes whose structural element is bent along the median longitudinal plane of the blade, and is deformable elastically.

Le dispositif d'emballage 10 comporte une coque inférieure 24 dans laquelle deux logements 26 sont réalisés, chaque logement 26 recevant un balai 12 associé.The packaging device 10 comprises a lower shell 24 in which two housings 26 are made, each housing 26 receiving a brush 12 associated.

Ici, l'ensemble comporte deux balais 12 et deux logements 26 formés dans le dispositif d'emballage 10. Il sera compris que l'invention n'est pas limitée à ce mode de réalisation, et que l'invention concerne aussi un dispositif d'emballage et un ensemble comportant un nombre différent de balais 12, le dispositif d'emballage 10 comporte alors le même nombre de logements 26.Here, the assembly comprises two brushes 12 and two housings 26 formed in the packaging device 10. It will be understood that the invention is not limited to this embodiment, and that the invention also relates to a packaging device and an assembly comprising a different number of brushes 12, the packaging device 10 then comprises the same number of housing 26.

Chaque logement 26 est d'orientation principale longitudinale, il est débouchant vers le haut comporte ainsi une face supérieure horizontale ouverte.Each housing 26 is of longitudinal main orientation, it is opening upwards and thus has an open horizontal top face.

Le logement 26 est délimité transversalement par deux parois latérales 35 longitudinales verticales entre lesquelles le balai 12 associé au logement 26 est reçu au moins en partie.The housing 26 is delimited transversely by two vertical longitudinal side walls 35 between which the brush 12 associated with the housing 26 is received at least in part.

Le dispositif d'emballage 10 est aussi réalisé de manière telle que l'élément de structure 14 et par conséquent les vertèbres 16 de chaque balai 12 sont redressés au moins en partie, réduisant ainsi l'encombrement global du dispositif d'emballage 10.The packaging device 10 is also made in such a way that the structural element 14 and consequently the vertebrae 16 of each brush 12 are at least partly straightened, thus reducing the overall size of the packaging device 10.

A cet effet, le dispositif d'emballage 10 est réalisé de manière que chaque balai 12 est maintenu dans une forme, ou position, au moins partiellement redressée selon son plan longitudinal médian, à l'intérieur du logement 26.For this purpose, the packaging device 10 is made in such a way that each blade 12 is held in a shape, or position, at least partially rectified along its median longitudinal plane, inside the housing 26.

Dans cette position redressée, l'élément de structure 14 et les vertèbres 16 de chaque balai 12 sont déformés élastiquement selon le plan longitudinal médian du balai 12.In this rectified position, the structural element 14 and the vertebrae 16 of each blade 12 are elastically deformed along the median longitudinal plane of the blade 12.

Selon l'invention, le maintien de chaque balai 12 dans sa position au moins partiellement redressée est réalisé directement par la coque inférieure 24 du dispositif d'emballage 10, qui comporte des zones d'appui et de maintien, aménagées dans les logements 26, qui coopèrent avec l'élément de structure 14 et les vertèbres 16 de chaque balai 12.According to the invention, the holding of each blade 12 in its at least partially rectified position is achieved directly by the lower shell 24 of the packaging device 10, which comprises support and support zones, arranged in the housing 26, which cooperate with the structural element 14 and the vertebrae 16 of each blade 12.

La coque inférieure 24 subit alors les efforts élastiques produits par l'élément de structure 14 et les vertèbres 16, pour qu'ils reprennent leur forme initiale.The lower shell 24 then undergoes the elastic forces produced by the structural element 14 and the vertebrae 16, so that they resume their original shape.

Pour améliorer la rigidité de la coque inférieure 24 vis-à-vis des efforts exercés par chaque balai 12, une nervure de rigidification 52 est aménagée entre deux logements 26 adjacents, et qui est apte à limiter la déformation de la coque inférieure 24 selon un plan longitudinal vertical.To improve the rigidity of the lower shell 24 vis-à-vis the forces exerted by each blade 12, a stiffening rib 52 is arranged between two housing 26 adjacent, and which is adapted to limit the deformation of the lower shell 24 in a vertical longitudinal plane.

Selon un mode de réalisation préféré, la nervure de rigidification 52 est délimitée latéralement par une paroi latérale 35 de chacun des deux logements 26, c'est-à-dire la paroi latérale 35 d'un logement 26 qui est située transversalement la plus proche de l'autre logement 26According to a preferred embodiment, the stiffening rib 52 is delimited laterally by a side wall 35 of each of the two housings 26, that is to say the side wall 35 of a housing 26 which is located transversely closest from the other dwelling 26

Les deux parois latérales 35 qui délimitent la nervure de rigidification 52 sont reliées à leurs extrémités supérieures par une bande horizontale 54.The two lateral walls 35 delimiting the stiffening rib 52 are connected at their upper ends by a horizontal band 54.

Les parois latérales 35 et la bande horizontale 54 sont réalisées venues de matière avec la coque inférieure 24. Ainsi, la nervure de rigidification 52 est réalisée venue de matière avec la coque inférieure 24, ce qui permet de limiter le nombre de composants du dispositif d'emballage 10.The lateral walls 35 and the horizontal strip 54 are made integral with the lower shell 24. Thus, the stiffening rib 52 is formed integrally with the lower shell 24, which limits the number of components of the device. packing 10.

Comme on l'a dit plus haut, chaque logement comporte des zones d'appui et de maintien qui coopèrent avec l'élément de structure 14 et les vertèbres 16 du balai 12 associé pour le maintien du balai 12 en position redressée.As mentioned above, each housing has bearing and retaining zones that cooperate with the structural element 14 and the vertebrae 16 of the brush 12 associated for the maintenance of the blade 12 in the rectified position.

Les zones d'appui et de maintien sont réalisées de manière à définir l'orientation du plan longitudinal médian du balai 12 par rapport à un plan longitudinal vertical médian du logement 26 associé.The bearing and holding zones are made so as to define the orientation of the median longitudinal plane of the blade 12 with respect to a median vertical longitudinal plane of the housing 26 associated.

Selon l'invention, les zones d'appui et de maintien sont réalisées de manière que le plan longitudinal médian de chaque balai 12 délimite avec le plan longitudinal vertical médian du logement associé un angle aigu, c'est-à-dire un angle dont la valeur est strictement inférieure à quatre-vingt-dix degrés (90°).According to the invention, the bearing and holding zones are made in such a way that the median longitudinal plane of each blade 12 delimits, with the median vertical longitudinal plane of the associated housing, an acute angle, that is to say an angle of which the value is strictly less than ninety degrees (90 °).

Selon un premier aspect de l'invention représenté aux figures 1 à 4, l'angle délimité par le plan longitudinal médian et ledit plan longitudinal vertical est d'environ quarante-cinq degrés (45°).According to a first aspect of the invention shown in Figures 1 to 4 the angle delimited by the median longitudinal plane and said vertical longitudinal plane is approximately forty-five degrees (45 °).

Comme on l'a représenté aux figures 1 à 4, la direction d'inclinaison de chaque balai 12 est définie de manière que le connecteur 20 du balai est décalé transversalement par rapport au plan longitudinal vertical médian du logement 26 associé en direction de l'autre logement 26.As has been shown to Figures 1 to 4 , the inclination direction of each blade 12 is defined so that the connector 20 of the brush is shifted transversely relative to the median vertical longitudinal plane of the housing 26 associated towards the other housing 26.

Les logements 26 sont décalés longitudinalement l'un par rapport à l'autre, et sont distants transversalement pour que les connecteurs 20 des deux balais 12 soient sensiblement alignés longitudinalement.The housings 26 are offset longitudinally relative to each other, and are spaced transversely so that the connectors 20 of the two brushes 12 are substantially aligned longitudinally.

Le connecteur 20 de chaque balai 12 est situé verticalement au droit de la nervure de rigidification 52.The connector 20 of each blade 12 is located vertically to the right of the stiffening rib 52.

Comme on peut le voir aux figures, chaque logement 26 comporte une première zone d'appui 28 et une seconde zone d'appui 28 qui sont décalées l'une par rapport à l'autre, contre chacune desquelles une première portion 31 et une deuxième portion 31 de l'élément de structure 14 sont en appui vers le bas, et comporte au moins une zone de maintien 30, sur laquelle une troisième portion 32 de l'élément de structure 14 du balai 12 est en appui, qui est agencée entre la première et la deuxième zones d'appui 28.As can be seen in the figures, each housing 26 comprises a first bearing zone 28 and a second bearing zone 28 which are offset relative to each other, against each of which a first portion 31 and a second portion 31 of the structural element 14 are supported downwards, and comprises at least one holding zone 30, on which a third portion 32 of the structural element 14 of the blade 12 bears, which is arranged between the first and second support zones 28.

Selon une variante de réalisation non représentée, le connecteur 20 du balai 12 est en appui contre la zone de maintien 30 pour le maintien du balai en position redressée.According to an alternative embodiment not shown, the connector 20 of the brush 12 bears against the holding zone 30 for holding the brush in the rectified position.

Les zones d'appui 28 et de maintien 30 sont conformées pour maintenir l'élément de structure 14 du balai 12 en position redressée par déformation élastique des vertèbres 16, en exerçant sur l'élément de structure 14 des efforts opposés globalement parallèles au plan longitudinal médian.The bearing and holding zones 30 are shaped to maintain the structural element 14 of the blade 12 in the straightened position by elastic deformation of the vertebrae 16, by exerting on the structural element 14 opposed forces that are generally parallel to the longitudinal plane. median.

Par exemple ici, la première zone d'appui 28 et la seconde zone d'appui 28 forment appui pour la première portion 31 et la deuxième portion 31 de l'élément de structure 14 selon un premier sens, le long du plan longitudinal médian, et la zone de maintien 30 forme une retenue pour la troisième portion 32 de l'élément de structure 14 selon un deuxième sens le long du plan longitudinal médian, opposé audit premier sens.For example here, the first bearing zone 28 and the second bearing zone 28 form a support for the first portion 31 and the second portion 31 of the structural element 14 in a first direction, along the median longitudinal plane, and the holding zone 30 forms a retaining for the third portion 32 of the structural element 14 in a second direction along the median longitudinal plane, opposite said first direction.

Ainsi que précédemment exposé, les zones d'appui 28 et de maintien 30 sont agencées de manière que le plan longitudinal médian délimite avec le plan longitudinal vertical médian du logement 26 associé un angle aigu non nul et inférieur à quatre-vingt dix degrés.As previously explained, the support and support zones 28 are arranged in such a way that the median longitudinal plane delimits with the median vertical longitudinal plane of the associated housing 26 an acute non-zero angle and less than ninety degrees.

Par conséquent, la première zone d'appui 28 et la seconde zone d'appui 28 sont globalement situées verticalement sous l'élément de structure 14 et la zone de maintien 30 est globalement située verticalement au dessus de la troisième portion 32 de l'élément de structure 14.Therefore, the first bearing zone 28 and the second bearing zone 28 are generally located vertically beneath the structural element 14 and the holding zone 30 is generally located vertically above the third portion 32 of the element of structure 14.

La troisième portion 32 de l'élément de structure 14 est alors en appui vers le haut contre la zone de maintien 30.The third portion 32 of the structural element 14 is then supported upwards against the holding zone 30.

Ainsi, la zone de maintien 30 réalise un blocage de l'élément de structure 14 du balai 12 en position globalement redressée dans le logement 26, en complément des efforts de frottement produits par l'appui élastique de l'élément de structure 14 contre les zones d'appui 28 et de maintient 30. La zone de maintien 30 forme aussi un élément de retenue du balai 12 dans le logement 26.Thus, the holding zone 30 blocks the structural element 14 of the blade 12 in a generally rectified position in the housing 26, in addition to the frictional forces produced by the elastic support of the structural element 14 against the The holding zone 30 also forms a retaining element of the blade 12 in the housing 26.

Cela permet de réduire les risques que le balai 12 ne se dégage du logement 26 ou de sa position redressée de manière imprévue.This reduces the risk that the blade 12 will emerge housing 26 or its unexpectedly rectified position.

Les première et seconde zones d'appui 28 définissent conjointement un plan longitudinal d'appui des première et deuxième portions 31 d'appui de l'élément de structure, qui est incliné par rapport à un plan horizontal selon le même angle d'inclinaison que le plan longitudinal médian par rapport audit plan longitudinal vertical.The first and second bearing zones 28 jointly define a longitudinal bearing plane of the first and second bearing portions 31 of the structural element, which is inclined with respect to a horizontal plane at the same angle of inclination as the median longitudinal plane with respect to said vertical longitudinal plane.

De plus, chacune des premières et secondes zones d'appui 28, est réalisée en deux parties agencées transversalement de part et d'autre du plan longitudinal médian.In addition, each of the first and second bearing zones 28 is made in two parts arranged transversely on either side of the median longitudinal plane.

Ces deux parties sont distantes l'une de l'autre, définissant un volume intermédiaire 33 dans lequel la lame 18 du balai 12 associé est reçue.These two parts are spaced from each other, defining an intermediate volume 33 in which the blade 18 of the brush 12 associated is received.

Ce volume intermédiaire 33 est réalisé pour que la lame 18 soit située à distance des parois du volume 33, comme on peut le voir notamment aux figures 2 et 3. Les risques que la lame 18 ne s'use par frottement contre ces parois, sont alors réduits.This intermediate volume 33 is made so that the blade 18 is located at a distance from the walls of the volume 33, as can be seen in particular in FIGS. Figures 2 and 3 . The risks that the blade 18 will wear out by friction against these walls, are then reduced.

Selon encore un autre aspect des première et seconde zones d'appui 28, les deux parties de la première zone d'appui 28 et de la seconde zone d'appui 28 sont reliées entre elles, de sorte que le logement 26 comporte deux nervures en vis-à-vis qui s'étendent longitudinalement sur sensiblement toute la longueur du logement 26.According to yet another aspect of the first and second bearing zones 28, the two parts of the first bearing zone 28 and of the second bearing zone 28 are interconnected, so that the housing 26 comprises two ribs vis-à-vis which extend longitudinally over substantially the entire length of the housing 26.

Les deux nervures font saillie transversalement vers l'intérieur du logement par rapport aux parois latérales du logement 26.The two ribs protrude transversely towards the interior of the housing relative to the side walls of the housing 26.

Ainsi, l'élément de structure 14 du balai est en appui sur ces deux nervures à ses extrémités transversales, par rapport au plan longitudinal médian du balai 12, et la lame 18 du balai 12 est reçue avec jeu entre les deux nervures.Thus, the structure element 14 of the brush is supported on these two ribs at its transverse ends, relative to the median longitudinal plane of the blade 12, and the blade 18 of the blade 12 is received with clearance between the two ribs.

Selon le mode de réalisation représenté aux figures 2 à 4, le logement 26 comporte une seule zone de maintien 30 qui s'étend transversalement vers l'intérieur du logement 26, depuis une paroi longitudinale verticale 35 du logement 26.According to the embodiment shown in Figures 2 to 4 , the housing 26 comprises a single holding zone 30 which extends transversely towards the inside of the housing 26, from a vertical longitudinal wall 35 of the housing 26.

La zone de maintien 30 du logement 26 forme alors une nervure d'orientation principale longitudinale, qui fait saillie transversalement vers l'intérieur du logement 26, par rapport à la paroi latérale 35 qui la porte.The holding zone 30 of the housing 26 then forms a longitudinally oriented main rib, which protrudes transversely towards the inside of the housing 26, with respect to the side wall 35 which carries it.

Selon le mode de réalisation selon lequel la zone de maintien 30 est en appui contre l'élément de structure 14 du balai 12, une découpe est réalisée dans la zone de maintien 30. Cette découpe est traversée par le connecteur 20 du balai 12, et divise alors la zone de maintien 30 en deux parties réparties de part et d'autre du connecteur 20.According to the embodiment in which the holding zone 30 bears against the structural element 14 of the blade 12, a cut is made in the holding zone 30. This cutout is traversed by the connector 20 of the blade 12, and then divides the holding zone 30 into two parts distributed on either side of the connector 20.

Selon le mode de réalisation de l'invention représenté aux figures, chaque balai 12 est maintenu en position redressée dans le logement 26 associé par les zones d'appui et de maintien dudit logement associé.According to the embodiment of the invention shown in the figures, each blade 12 is held in a rectified position in the housing 26 associated with the support zones and maintaining said associated housing.

Ainsi, chaque logement 26 comporte une première zone d'appui 28, une seconde zone d'appui 28 et une zone de maintien 30.Thus, each housing 26 has a first bearing zone 28, a second bearing zone 28 and a holding zone 30.

Selon une variante de réalisation comme cela sera présenté dans le cadre des figures 5 et suivantes, un premier balai 12 réalise le maintien de l'autre balai 12 dans le logement associé.According to a variant embodiment, as will be presented in the context of the figures 5 and following, a first blade 12 carries the maintenance of the other brush 12 in the associated housing.

Pour cela, le premier balai 12 est en appui contre l'autre balai 12, et seul le logement 26 associé au premier balai 12 comporte au moins une zone de maintien 30.For this, the first brush 12 bears against the other brush 12, and only the housing 26 associated with the first brush 12 comprises at least one holding zone 30.

Le logement 26 associé au premier balai 12 comporte alors une première zone d'appui 28, une seconde zone d'appui 28 et une zone de maintien 30, et le logement 26 associé à l'autre balai 12, comporte uniquement une première zone d'appui 28 et une seconde zone d'appui 28.The housing 26 associated with the first blade 12 then comprises a first bearing zone 28, a second bearing zone 28 and a holding zone 30, and the housing 26 associated with the other blade 12 comprises only a first zone 26 support 28 and a second support zone 28.

Chaque zone de maintien 30 est portée par la paroi latérale 35 du logement 26 associé, qui est située transversalement à proximité de l'autre logement 26, c'est-à-dire qu'elle est portée par une paroi latérale 35 qui délimite la nervure de rigidification 52 de la coque inférieure 24.Each holding zone 30 is carried by the side wall 35 of the associated housing 26, which is located transversely close to the other housing 26, that is to say that it is carried by a side wall 35 which delimits the stiffening rib 52 of the lower shell 24.

La zone de maintien 30 est réalisée venue de matière avec la paroi latérale 35 qui la porte. La forme particulière de la zone de maintien 30 permet d'améliorer la rigidité de la nervure 52 de rigidification.The holding zone 30 is formed integrally with the side wall 35 which carries it. The particular shape of the holding zone 30 makes it possible to improve the rigidity of the stiffening rib 52.

L'introduction de chaque balai 12 dans le logement 26 associé s'effectue selon un mouvement d'insertion globalement vertical vers le bas, et comporte une première phase dans laquelle la première portion 31 et la deuxième portion 31 de l'élément de structure 14 au niveau de chacune des extrémités 12a du balai 12 sont mises en contact avec la première et la seconde zone d'appui 28, respectivement.The introduction of each brush 12 in the associated housing 26 is carried out in a generally vertical downward insertion movement, and comprises a first phase in which the first portion 31 and the second portion 31 of the structural element 14 at each of the ends 12a of the blade 12 are brought into contact with the first and the second bearing zone 28, respectively.

Ensuite, l'élément de structure 14 du balai 12 est redressé par un effort vers le bas exercé sur une partie centrale de l'élément de structure 14, de manière à le déformer élastiquement.Then, the structural element 14 of the blade 12 is straightened by a downward force exerted on a central portion of the structural element 14, so as to deform elastically.

Enfin, lorsque la troisième portion 32 de l'élément de structure 14 est située à une cote verticale inférieure à celle de la zone de maintien 30, la troisième portion 32 est positionnée sous la zone de maintien 30.Finally, when the third portion 32 of the structural element 14 is located at a lower vertical dimension than that of the holding zone 30, the third portion 32 is positioned under the holding zone 30.

Les vertèbres 16 du balai 12 sont alors au moins partiellement redressées, c'est-à-dire que leur courbure selon le plan longitudinal médian est moindre que lorsque le balai 12 est au repos, et du fait de leur déformation élastique, les vertèbres exercent un effort de rappel vers leur forme cintrée au repos, qui est transmis aux zones d'appui 28 et de maintien 30.The vertebrae 16 of the blade 12 are then at least partially straightened, that is to say that their curvature along the median longitudinal plane is less than when the blade 12 is at rest, and because of their elastic deformation, the vertebrae exert a restoring force towards their curved form at rest, which is transmitted to the bearing and holding zones 30.

L'ensemble comporte plusieurs balais 12, ici deux balais 12, qui sont reçus dans plusieurs logements 26 associés.The assembly comprises several brushes 12, here two brushes 12, which are received in several associated housing 26.

Le dispositif d'emballage 10 comporte une feuille horizontale 34 supérieure qui relie les logements 26, au niveau de leurs extrémités supérieures ouvertes. La feuille 34 comporte ainsi deux ouvertures horizontales par lesquelles les logements sont débouchants vers le haut et au travers desquelles les balais 12 sont introduits dans les logements 26.The packaging device 10 comprises a top horizontal sheet 34 which connects the housings 26, at their open upper ends. The sheet 34 thus comprises two horizontal openings through which the housings are opening upwards and through which the brushes 12 are introduced into the housings 26.

La bande supérieure horizontale 54 de la nervure de rigidification 52 est de préférence formée dans cette feuille horizontale 34.The upper horizontal strip 54 of the stiffening rib 52 is preferably formed in this horizontal sheet 34.

La coque inférieure 24 du dispositif d'emballage 10 est réalisée de manière que l'élément de structure 14, les vertèbres 16 et la lame 18 de chaque balai 12 sont situés verticalement au dessous de la feuille 34. Seul le connecteur 20 de chaque balai 12 fait saillie vers le haut par rapport à la feuille 34.The lower shell 24 of the packaging device 10 is made such that the structural element 14, the vertebrae 16 and the blade 18 of each blade 12 are located vertically below the sheet 34. Only the connector 20 of each blade 12 protrudes upwardly relative to the sheet 34.

La feuille 34 définit un plan d'appui pour une coque supérieure 36 du dispositif d'emballage 10 qui réalise notamment la fermeture de chaque logement 26, pour protéger les balais 12 contre l'humidité ou les poussières.The sheet 34 defines a support plane for an upper shell 36 of the packaging device 10 which performs in particular the closure of each housing 26, to protect the brushes 12 against moisture or dust.

Comme on peut le voir aux figures 2 à 4, la coque supérieure 36 comporte un flan inférieur 38 horizontal qui est en appui vers le bas contre la feuille 34 en vis-à-vis de la coque inférieure 24, et un dôme supérieur 40 ouvert vers le bas.As can be seen at Figures 2 to 4 , the upper shell 36 has a lower horizontal blank 38 which is supported downwards against the sheet 34 vis-à-vis the lower shell 24, and an upper dome 40 open downwards.

La coque supérieure 36 est en outre réalisée de manière que le dôme supérieur 40 recouvre les connecteurs 20 des deux balais 12.The upper shell 36 is furthermore made in such a way that the upper dome 40 covers the connectors 20 of the two brushes 12.

Ainsi, la coque supérieure 36 comporte un seul dôme supérieur 40 commun aux deux logements 26 de la coque inférieure 24. De plus, les dimensions du dôme supérieur 40 unique sont adaptées aux dimensions des connecteurs 20, de sorte que le volume du dôme 40 est limité, limitant par conséquent la quantité de matière utilisée.Thus, the upper shell 36 has a single upper dome 40 common to the two housings 26 of the lower shell 24. In addition, the dimensions of the single upper dome 40 are adapted to the dimensions of the connectors 20, so that the volume of the dome 40 is limited, thus limiting the amount of material used.

Les logements 26 sont obturés par le flan 38 et par le dôme supérieur 40 de la coque supérieure 36.The housings 26 are closed by the blank 38 and by the upper dome 40 of the upper shell 36.

La coque supérieure 36 est généralement réalisée en matière plastique transparente.The upper shell 36 is generally made of transparent plastic material.

Selon un autre aspect du dispositif d'emballage 10 selon l'invention, un insert 42 est agencé entre la feuille 34 de la coque inférieure 24 et le flan 38 de la coque supérieure 36.According to another aspect of the packaging device 10 according to the invention, an insert 42 is arranged between the sheet 34 of the lower shell 24 and the blank 38 of the upper shell 36.

Cet insert 42 consiste par exemple en une feuille de papier, de carton ou de plastique, sur lequel diverses informations sont imprimées, comme par exemple la marque et le modèle des balais 12, et/ou une notice de montage des balais 12.This insert 42 consists for example of a sheet of paper, cardboard or plastic, on which various information is printed, such as the brand and the model of the brushes 12, and / or a mounting instructions of the brushes 12.

A titre de variante, le dispositif d'emballage comporte deux inserts 42 qui sont agencés longitudinalement de part et d'autre des connecteurs 20 des balais 12.As a variant, the packaging device comprises two inserts 42 which are arranged longitudinally on either side of the connectors 20 of the brushes 12.

Selon une autre variante, l'insert 42 est formé d'une ou de plusieurs feuilles pliées une ou plusieurs fois, selon la quantité d'informations qui sont imprimées sur l'insert 42.According to another variant, the insert 42 is formed of one or more sheets folded one or more times, depending on the amount of information that is printed on the insert 42.

On a représenté aux figures 2, 3 et 4 divers modes de liaison entre la coque inférieure 24 et la coque supérieure 36.Representatives Figures 2, 3 and 4 various modes of connection between the lower shell 24 and the upper shell 36.

A la figure 2, la coque inférieure 24 et la coque supérieure 36 sont reliées entre elles au niveau des bords 34a, 38a de la feuille 34 et du flan 38, respectivement, qui sont collés ou soudés l'un sur l'autre.To the figure 2 , the lower shell 24 and the upper shell 36 are interconnected at the edges 34a, 38a of the sheet 34 and blank 38, respectively, which are glued or welded to one another.

Le soudage des bords 34a, 38a est par exemple un soudage par ultrasons ou un soudage thermique.Edge welding 34a, 38a is, for example, ultrasonic welding or thermal welding.

Aux figures 3 et 4, la feuille 34 de la coque inférieure 24 comporte une aile 44 qui s'étend globalement verticalement vers le bas depuis le bord 34a de la feuille 34. Le flan 38 de la coque supérieure 36 comporte lui aussi une aile 46 associée à l'aile 44 de la feuille 34, et qui s'étend vers le bas depuis le bord 38a du flan 38.To the figures 3 and 4 , the sheet 34 of the lower shell 24 has a flange 44 which extends generally vertically downwardly from the edge 34a of the sheet 34. The blank 38 of the upper shell 36 also has a wing 46 associated with the wing 44 of the sheet 34, and which extends downwardly from the edge 38a of the blank 38.

De préférence, chaque bord 34a, 38a de la feuille 34 ou du flan 38 porte une aile 44, 46.Preferably, each edge 34a, 38a of the sheet 34 or blank 38 carries a wing 44, 46.

L'aile 46 de la coque supérieure comporte en outre des bossages 48 qui font saillie transversalement par rapport à la face de l'aile 46 située en vis-à-vis de l'aile 44 de la coque inférieure 24, et qui sont reçus dans des ouvertures (non représentées) aménagées dans l'aile 44 de la coque inférieure 24.The wing 46 of the upper shell further comprises bosses 48 which protrude transversely with respect to the face of the wing 46 situated opposite the wing 44 of the lower shell 24, and which are received in openings (not shown) arranged in the wing 44 of the lower shell 24.

Les ailes 44, 46 sont solidarisées entre elles au niveau de leurs bords inférieurs 44a, 46a respectifs par collage ou par soudage, par exemple.The wings 44, 46 are joined together at their respective lower edges 44a, 46a by gluing or welding, for example.

Les ailes 44, 46 permettent d'améliorer la rigidité du dispositif d'emballage 10, car celui-ci est soumis à des contraintes mécaniques importantes, qui sont générées par la déformation élastique de chaque balai 12.The wings 44, 46 make it possible to improve the rigidity of the packaging device 10, since this is subjected to significant mechanical stresses, which are generated by the elastic deformation of each blade 12.

De plus, les ailes 44, 46 permettent de faciliter le montage de la coque supérieure 36 sur la coque inférieure 24, en formant des rampes inclinées de guidage.In addition, the wings 44, 46 facilitate the mounting of the upper shell 36 on the lower shell 24, forming inclined guide ramps.

Selon encore une autre variante de réalisation représentée à la figure 4, le dispositif d'emballage 10 comporte un élément de renfort 50 fixé sous la coque inférieure 24 et qui participe à la rigidification du dispositif d'emballage 10, pour supporter les efforts résultants de la déformation élastique de chaque balai 12.According to yet another variant embodiment represented in figure 4 , the packaging device 10 comprises a reinforcing element 50 fixed under the lower shell 24 and which contributes to the stiffening of the packaging device 10, to withstand the efforts resulting from the elastic deformation of each blade 12.

Pour permettre de disposer l'ensemble comportant le dispositif d'emballage 10 et les deux balais 12, dans un rayonnage de magasin, la coque supérieure 36 et la coque inférieure 24 sont réalisées de manière qu'un trou conventionnel 50 qui est apte à être traversé par une tige du rayonnage est formé à une extrémité longitudinale du dispositif d'emballage 10,To make it possible to arrange the assembly comprising the packaging device 10 and the two brushes 12, in a magazine rack, the upper shell 36 and the lower shell 24 are made so that a conventional hole 50 which is adapted to be traversed by a rack rod is formed at a longitudinal end of the packaging device 10,

Ainsi, lorsque l'ensemble comportant le dispositif d'emballage 10 et les deux balais 12 est disposé dans le rayonnage, l'orientation longitudinale L telle que représenté aux figures, est alors verticale sous l'action de la gravité terrestre.Thus, when the assembly comprising the packaging device 10 and the two brushes 12 is disposed in the rack, the longitudinal orientation L as shown in the figures, is then vertical under the action of Earth's gravity.

De plus, selon le mode de réalisation pour lequel la zone de maintien 30 comporte une découpe traversée par le connecteur 20 du balai 12, les parties de la zone de maintien 30 forment des butées du connecteur 20 selon la direction longitudinale L. Cela permet de maintenir longitudinalement le balai 12 en position dans le logement 26.In addition, according to the embodiment for which the holding zone 30 comprises a cut-out through which the connector 20 of the blade 12 passes, the portions of the holding zone 30 form stops of the connector 20 in the longitudinal direction L. This makes it possible to longitudinally maintain the blade 12 in position in the housing 26.

La figure 5 présente un autre mode de réalisation du dispositif d'emballage dans lequel deux balais d'essuyage sont reçus.The figure 5 presents another embodiment of the packaging device in which two wiping brushes are received.

La présentation de ce mode de réalisation et des différentes figures qui lui sont associées (figures 5 à 7) vient en complément de l'ensemble de la description faite dans le cadre des figures 2 à 4 présentant l'agencement d'un balai 12 dans un logement 26 de l'emballage 10.The presentation of this embodiment and the different figures associated with it ( Figures 5 to 7 ) is complementary to the whole of the description made in the context of the Figures 2 to 4 presenting the arrangement of a broom 12 in a housing 26 of the package 10.

Dans ce mode de réalisation les deux balais 12 sont reçus entièrement dans les logements 26 de la coque 24. On voit en particulier que les connecteurs 20 ne dépassent pas de la coque 24 car les parois latérales 35 des logements 26 sont plus hautes que celles présentées dans le mode de réalisation des figures 1 à 4. Ainsi, dans le cas présent et comme visible sur les figures 6A à 6D, la coque 24 peut être fermée à l'aide d'un film 41 qui peut être directement scellé sur la feuille horizontale 34 reliant les logements 26 au niveau de leurs extrémités supérieures ouvertes. Ce film 41 vient obturer la coque 24 mais il permet également d'éviter que la coque 24 ne s'écarte sous l'action des forces de rappel générées par les balais 12 en position rangée dans les logements 26. En effet, au fil du temps, on peut craindre une altération des propriétés du plastique formant la coque 24 et une dégradation du maintien des balais 12 dans le dispositif d'emballage 10. Grâce au film 41, la coque 24 est rigidifiée et ne peut plus être amenée à s'ouvrir vers l'extérieur.In this embodiment the two brushes 12 are received entirely in the housing 26 of the shell 24. In particular, it can be seen that the connectors 20 do not protrude from the shell 24 because the side walls 35 of the housing 26 are higher than those presented. in the embodiment of Figures 1 to 4 . So, in this case and as visible on the Figures 6A to 6D , the shell 24 may be closed with a film 41 which can be directly sealed to the horizontal sheet 34 connecting the housing 26 at their open upper ends. This film 41 closes the shell 24 but it also prevents the shell 24 from deviating under the action of the return forces generated by the brushes 12 in the stowed position in the 26. As a matter of fact, over time, it is possible to fear an alteration of the properties of the plastic forming the shell 24 and a degradation of the maintenance of the brushes 12 in the packaging device 10. Thanks to the film 41, the shell 24 is stiffened and can no longer be opened to the outside.

Par ailleurs, pour empêcher tout appui sur la coque 24, au risque d'endommager les balais 12, un insert 42 rigide est agencé dans la coque 24 au niveau de la feuille 34 et est recouvert par le film 41.Moreover, to prevent any support on the shell 24, at the risk of damaging the brushes 12, a rigid insert 42 is arranged in the shell 24 at the level of the sheet 34 and is covered by the film 41.

Les variantes relatives à l'insert 42 présentées dans le cadre du premier mode de réalisation sont également envisageables dans le mode de réalisation des figures 5 à 7.The variants relating to the insert 42 presented in the context of the first embodiment are also conceivable in the embodiment of the Figures 5 to 7 .

Concernant le positionnement des balais 12 dans les logements 26 (figures 6A à 6D), celui-ci est similaire au positionnement présenté aux figures 2 et 3 dans le cas d'un balai unique mais fait apparaître l'agencement des deux balais dans le dispositif d'emballage.Regarding the positioning of the brushes 12 in the housing 26 ( Figures 6A to 6D ), this is similar to the positioning presented to Figures 2 and 3 in the case of a single broom but shows the arrangement of the two brushes in the packaging device.

Les figures 6A à 6D présentent différentes coupes respectivement suivant les lignes 6A-6A, 6B-6B, 6C-6C, 6D-6D transversales de l'ensemble présenté à la figure 5.The Figures 6A to 6D have different cuts respectively along the lines 6A-6A, 6B-6B, 6C-6C, 6D-6D transverse of the assembly presented in the figure 5 .

Comme on peut le voir de la figure 5 et des vues en coupe, les balais 12 sont de taille différente. En effet, sur la coupe de la figure 6A-6A, le balai de droite est pourvu de son embout terminal 12a alors que pour l'autre balai ce n'est pas le cas.As can be seen from the figure 5 and sectional views, the brushes 12 are of different size. Indeed, on the cut of the Figure 6A-6A , the right broom is provided with its terminal end 12a while for the other broom it is not the case.

De la même manière, le balai 12 est retenu dans le logement 26 grâce aux moyens de positionnement formés des zones d'appui 28 et de la zone de maintien 30. Comme visible sur les différentes vues en coupe, les zones d'appui 28 s'étendent longitudinalement sensiblement sur toute la longueur des logements 26 formant deux nervures en vis-à-vis. Ces nervures font saillies transversalement vers l'intérieur de chaque logement par rapport aux parois latérales de ceux-ci.In the same way, the blade 12 is retained in the housing 26 by the positioning means formed of the bearing zones 28 and the holding zone 30. As can be seen in the various sectional views, the bearing zones 28 extend longitudinally substantially over the entire length of the housing 26 forming two ribs vis-à-vis. These ribs project transversely inwardly of each housing relative to the side walls thereof.

La zone de maintien 30 forme quant à elle une nervure d'orientation principale longitudinale faisant saillies transversalement à l'intérieur du logement 26 par rapport à la paroi latérale 35 qui la porte. Par contre, la zone de maintien 30 ne s'étend pas sur toute la longueur des logements 26 mais sur certaines portions de ceux-ci.The holding zone 30 forms a rib with longitudinal main orientation protruding transversely inside the housing 26 relative to the side wall 35 which carries it. By cons, the holding zone 30 does not extend over the entire length of the housing 26 but on some portions thereof.

On pourra donc avoir une alternance de zones de maintien 30 du logement 26 de droite et de zones de maintien 30 du logement 26 de gauche sur la longueur du dispositif d'emballage 10.It will thus be possible to have an alternation of retaining zones 30 of the housing 26 on the right and of retaining zones 30 of the housing 26 on the left along the length of the packaging device 10.

Sur la figure 6A, au niveau du logement de gauche, les première et seconde portions 31 agencées sur une extrémité 12a du balai sont en appui sur les premières et seconde zones d'appui 28 du logement 26 alors qu'au niveau du logement de droite, le balai n'est localement retenu par aucun moyen de positionnement.On the Figure 6A , at the level of the housing on the left, the first and second portions 31 arranged on one end 12a of the brush bear on the first and second bearing zones 28 of the housing 26 while at the right housing, the brush n is locally restrained by any positioning means.

Sur la figure 6B, au niveau du logement de gauche, le balai est retenu au niveau de sa troisième portion 32 par la zone de maintien 30 alors qu'au niveau du logement de droite, le balai n'est localement retenu par aucun moyen de positionnement.On the Figure 6B at the left housing, the broom is retained at its third portion 32 by the holding zone 30 while at the right housing, the broom is locally retained by any positioning means.

Sur la figure 6C, au niveau du logement de gauche, le balai est retenu au niveau de sa troisième portion 32 par la zone de maintien 30 alors qu'au niveau du logement de droite, le balai n'est localement retenu par aucun moyen de positionnement puisque la coupe est réalisée au niveau du connecteur 20 du balai de droite.On the Figure 6C at the left housing, the blade is retained at its third portion 32 by the holding zone 30 while at the right housing, the blade is not locally retained by any positioning means since the cut is performed at the connector 20 of the right broom.

Sur la figure 6D, au niveau du logement de gauche, le balai est retenu au niveau de sa troisième portion 32 par la zone de maintien 30 alors qu'au niveau du logement de droite, le balai n'est localement retenu par aucun moyen de positionnement. On observera tout de même la présence d'un bossage 39 d'anti-rotation porté par la paroi latérale 35 extérieure du logement 26 de droite.On the Figure 6D at the left housing, the broom is retained at its third portion 32 by the holding zone 30 while at the right housing, the broom is locally retained by any positioning means. Nevertheless, the presence of an anti-rotation boss 39 carried by the outer side wall of the housing 26 on the right will be observed.

Ce bossage 39 permet d'éviter un éventuel retournement et/ou une torsion localisée du balai 12 dans le logement 26. Ce bossage n'est pas considéré comme un moyen de maintien car sa suppression n'altère pas le maintien du balai 12 dans son logement 26.This boss 39 avoids a possible reversal and / or a localized twist of the blade 12 in the housing 26. This boss is not considered a means of maintenance because its deletion does not alter the maintenance of the blade 12 in its housing 26.

Comme visible sur la figure 6D, le bossage 39 est en contact avec une vertèbre 16 du balai 12 mais on pourrait envisager que le contact se fasse avec un autre élément du balai 12.As visible on the Figure 6D , the boss 39 is in contact with a vertebra 16 of the blade 12 but it could be envisaged that the contact is made with another element of the blade 12.

De même que précédemment exposé, pour améliorer la rigidité de la coque inférieure 24 vis-à-vis des efforts exercés par chaque balai 12, une nervure de rigidification 52 est aménagée entre deux logements 26 adjacents. Cette nervure 52 est apte à limiter la déformation de la coque inférieure 24 selon un plan longitudinal vertical.As previously discussed, to improve the rigidity of the lower shell 24 vis-à-vis the forces exerted by each blade 12, a stiffening rib 52 is arranged between two adjacent housing 26. This rib 52 is able to limit the deformation of the lower shell 24 in a vertical longitudinal plane.

Grâce à ce positionnement incliné des balais 12 dans chacun des logements 26 (inclinaison du plan longitudinal médian du balai 12 par rapport au logement 26) il est possible de réduire l'encombrement vertical du dispositif d'emballage 10.Thanks to this inclined positioning of the brushes 12 in each of the housing 26 (inclination of the median longitudinal plane of the blade 12 relative to the housing 26) it is possible to reduce the vertical dimensions of the packaging device 10.

Par ailleurs, en complément de ce positionnement incliné des balais dans les logements 26, ceux-ci sont décalés longitudinalement l'un par rapport à l'autre, de manière que les connecteurs 20 des balais 12 reçus dans les logements 26 soient eux aussi décalés longitudinalement l'un par rapport à l'autre. Chaque connecteur est ainsi reçu dans son entier dans la coque 24 ce qui permet de minimiser l'encombrement du dispositif d'emballage 10 et de simplifier le dispositif d'emballage 10.Furthermore, in addition to this inclined positioning of the brushes in the housings 26, they are offset longitudinally with respect to each other, so that the connectors 20 of the brushes 12 received in the housing 26 are also offset longitudinally with respect to each other. Each connector is thus received in its entirety in the shell 24, which makes it possible to minimize the bulk of the packaging device 10 and to simplify the packaging device 10.

Notons également que ce positionnement incliné des balais 12 associé aux moyens de positionnement utilisés permet une compensation des forces exercées par chaque balai 12 sur le logement 26 associé de sorte que le dispositif d'emballage se trouve stabilisé.Note also that this inclined positioning of the brushes 12 associated with the positioning means used allows compensation of the forces exerted by each blade 12 on the associated housing 26 so that the packaging device is stabilized.

Selon un autre mode de réalisation de l'invention, présenté à la figure 7, le balai 12 peut présenter une structure différente. Ainsi, dans ce balai 12, l'élément de structure 14 délimite un logement tubulaire 14a dans lequel une vertèbre 16 unique est reçue et la lame d'essuyage 18 est portée par des griffes du logement tubulaire 14a. Dans le cas présent, l'élément de structure 14 intègre un déflecteur aérodynamique.According to another embodiment of the invention, presented to the figure 7 , the broom 12 may have a different structure. Thus, in this broom 12, the structural element 14 defines a tubular housing 14a in which a single vertebra 16 is received and the wiper blade 18 is carried by claws of the tubular housing 14a. In this case, the structural element 14 incorporates an aerodynamic deflector.

De la même manière que précédemment, le logement 26 présente des moyens de positionnement comprenant des zones d'appui 28 et une zone de maintien 30, différentes portions du balai 12 étant destinées à coopérer avec ces différentes zones. Notamment, les premières et deuxièmes portions 31 sont destinées à prendre appui sur les zones d'appui 28 et la troisième portion 32 est destinée à être retenue par la zone de maintien 30.In the same way as before, the housing 26 has positioning means comprising bearing zones 28 and a holding zone 30, different portions of the blade 12 being intended to cooperate with these different zones. In particular, the first and second portions 31 are intended to bear on the bearing zones 28 and the third portion 32 is intended to be retained by the holding zone 30.

Dans le cas présent, la troisième portion 32 est localisée le déflecteur aérodynamique intégré au logement tubulaire 14a. Du fait de la structure différente de ce balai 12, on constate qu'il est en contact et retenu au niveau des différentes zones, zones d'appui 28 et zone de maintien 30.In this case, the third portion 32 is located the aerodynamic deflector integrated tubular housing 14a. Due to the different structure of this blade 12, it is found that it is in contact and retained at the different zones, bearing zones 28 and holding zone 30.

Sur la figure 7, on n'a représenté qu'un seul logement 26 mais le dispositif d'emballage peut présenter deux logements 26 pour accueillir deux balais 12 comme dans le cas des figures 5 et 6A à 6D.On the figure 7 only one housing 26 has been shown, but the packaging device may have two housings 26 for accommodating two brushes 12, as in the case of figures 5 and 6A to 6D .

Il sera compris que l'invention ne se limite pas à ces deux seuls modes de réalisation des balais 12, et qu'elle concerne plus généralement les balais dont l'élément de structure est cintré selon le plan longitudinal médian du balai, et est déformable élastiquement.It will be understood that the invention is not limited to these two only embodiments of the brushes 12, and more generally relates to the brushes whose structural element is bent along the median longitudinal plane of the blade, and is deformable elastically.

Ainsi, on entend par élément de structure un élément du type support de lame, support de vertèbre, déflecteur, ou encore vertèbre de balai d'essuyage ou encore une combinaison de deux ou plusieurs de ces éléments.Thus, structural element means a member of the blade support type, vertebra support, deflector, or wiper blade vertebra or a combination of two or more of these elements.

Bien évidemment, localement le balai, par ses embouts terminaux ou son connecteur, peut être en contact avec le logement 26 du dispositif d'emballage 10.Of course, locally the broom, by its end caps or connector, may be in contact with the housing 26 of the packaging device 10.
