Abstract
Description
Le présent brevet concerne un dispositif de recouvrement du pare-brise deThe present patent relates to a device for covering the windshield of
véhicule contre les intempéries (gel, givre, grêle...) l'hiver, et contre les rayons du soleil l'été. Il est vehicle against bad weather (frost, frost, hail ...) in winter, and against the rays of the sun in summer. It is
constitué d'une plaque alvéolaire en matière synthétique adaptée à la dimension du pare-brise et pouvant être pliée pour son rangement. made of a synthetic honeycomb plate adapted to the size of the windshield and which can be folded for storage.
Ce dispositif vise à améliorer le dispositif de recouvrement de parebrise décrit par le brevet EP0377598. This device aims to improve the windshield covering device described by patent EP0377598.
Le brevet EP0377598 décrit une plaque double alvéolaire plane et mince pouvant être pliée et adaptée à la dimension du pare brise. Cette plaque alvéolaire présente de préférence deux lignes de pliages prévus sur environ un tiers de sa longueur. Ceci permet d'adapter la plaque double alvéolaire de manière avantageuse à la courbure du pare-brise, et les lignes de pliage sont destinées en outre à permettre un pliage facile et peu encombrant de la plaque double alvéolaire. Patent EP0377598 describes a flat and thin double alveolar plate which can be folded and adapted to the size of the windshield. This honeycomb plate preferably has two fold lines provided over about a third of its length. This makes it possible to adapt the double honeycomb plate in an advantageous manner to the curvature of the windshield, and the fold lines are further intended to allow easy and space-saving folding of the double honeycomb plate.
La surface d'un tel dispositif une fois dépliée est importante afin de couvrir une surface suffisante du pare-brise. Par conséquent la réalisation des lignes de pliage est un élément majeur à prendre en compte si l'on veut obtenir un produit facile à plier et à déplier, et en position pliée facile à manipuler et à ranger. La réalisation de ces lignes de pliages doit également préserver la facilité de mise en oeuvre du dispositif sur le pare-brise. The surface of such a device when unfolded is important in order to cover a sufficient surface of the windshield. Consequently, the production of the folding lines is a major element to be taken into account if one wants to obtain a product which is easy to fold and unfold, and in a folded position which is easy to handle and store. The production of these fold lines must also preserve the ease of use of the device on the windshield.
Le dispositif du présent brevet vise à améliorer le dispositif constituant la base du brevet EP0377598 par la description de la réalisation des lignes de pliages sur la plaque alvéolaire. The device of the present patent aims to improve the device constituting the basis of patent EP0377598 by describing the production of the fold lines on the honeycomb plate.
La plaque est constituée de deux feuilles reliées entre 35 elles par une multitude d'âmes. En opérant des découpes d'un bord à l'autre de la plaque, d'une profondeur telle qu'elles s'arrêtent avant la 2ème feuille, il se crée naturellement une zone de moindre résistance au niveau de ces découpes permettant ainsi un pliage et un dépliage aisés de la plaque à leur niveau, rendus possibles par l'élasticité de la matière. The plate consists of two sheets interconnected by a multitude of cores. By making cuts from one edge of the plate to the other, of a depth such that they stop before the 2nd sheet, a zone of least resistance is naturally created at the level of these cuts, thus allowing bending. and easy unfolding of the plate at their level, made possible by the elasticity of the material.
Cette forme de réalisation des lignes de pliage par ce procédé de découpe est d'une part très économique, car elle demande de faibles moyens de production pour sa réalisation et sur des plaques standards; et d'autre part permet par ses caractéristiques (pliage possible dans un seul sens) de conserver une meilleure rigidité du dispositif pour sa mise en place sur le pare-brise comparé à d'autres formes de réalisation de pliage(rainage ou pliage à chaud par exemple). This embodiment of the folding lines by this cutting process is on the one hand very economical, because it requires low production means for its production and on standard plates; and on the other hand allows by its characteristics (folding possible in one direction) to maintain a better rigidity of the device for its installation on the windshield compared to other embodiments of folding (creasing or hot folding for example).
Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du dispositif qu'elle concerne. For its proper understanding, the invention is described again below with reference to the appended schematic drawing showing, by way of non-limiting example, a preferred embodiment of the device to which it relates.
La figure 1 représente une plaque alvéolaire (1) en matière synthétique ( par exemple du type polypropylène) et est d'une forme telle qu'elle couvre la surface du pare-brise. FIG. 1 represents a cellular plate (1) made of synthetic material (for example of the polypropylene type) and is of a shape such that it covers the surface of the windshield.
Cette plaque alvéolaire comporte 2 feuilles (2) et (3) reliées entre elles par plusieurs âmes(4) de préférence parallèles entre elles. This honeycomb plate comprises 2 sheets (2) and (3) interconnected by several cores (4) preferably parallel to each other.
Cette plaque présente une ou plusieurs découpes(5) perpendiculaires dans l'exemple aux âmes(4), d'un bord à l'autre de la plaque, traversant la 1 ère feuille (2) et d'une profondeur telle qu'elles s'arrêtent avant la 2ème feuille(3), entraînant ainsi la création d'une zone de moindre résistance à leurs niveaux pour permettre le pliage et le dépliage plus aisés de la plaque. This plate has one or more cutouts (5) perpendicular in the example to the webs (4), from one edge to the other of the plate, crossing the 1 st sheet (2) and of a depth such that they stop before the 2nd sheet (3), thus creating a zone of least resistance at their levels to allow easier folding and unfolding of the plate.
Tel que montré sur la figure 2 ces découpes peuvent être sur la même face de la plaque (sur une seule feuille) et ainsi permettre un pliage du dispositif sur lui-même. As shown in Figure 2 these cutouts can be on the same face of the plate (on a single sheet) and thus allow folding of the device on itself.
Cette forme de réalisation a l'avantage de permettre une meilleure rigidité du dispositif dans sa mise en oeuvre sur le pare brise. En effet dans ce cas, en appliquant le dispositif avec les découpes(5) face au pare-brise, les bords respectifs (6)(7) de chaque découpe(5) viennent en contact sous le poids de la plaque redonnant ainsi une rigidité proche de celle qu'avait la plaque avant les découpes. This embodiment has the advantage of allowing better rigidity of the device in its implementation on the windshield. Indeed in this case, by applying the device with the cutouts (5) facing the windshield, the respective edges (6) (7) of each cutout (5) come into contact under the weight of the plate thus restoring rigidity close to that of the plate before the cuts.
Cette rigidité est accrue dans le cas d'une réalisation des découpes perpendiculaires ou obliques aux âmes(4) en raison d'une surface de contact des bords respectifs(6)(7) plus grande. This rigidity is increased in the case of making the cutouts perpendicular or oblique to the webs (4) due to a larger contact surface of the respective edges (6) (7).
Tel que montré sur la figure 3 ces découpes peuvent être alternées par rapport aux faces de la plaque (sur une feuille (2) puis sur l'autre (3)) et ainsi permettre un pliage du dispositif en accordéon. As shown in FIG. 3, these cutouts can be alternated with respect to the faces of the plate (on one sheet (2) then on the other (3)) and thus allow folding of the accordion device.
Il va de soi que l'invention n'est pas limitée aux formes de réalisation décrites ci-dessus à titre d'exemple, mais qu'elle embrasse au contraire, toutes les variantes de réalisation. Ainsi la plaque pourrait comprendre des découpes obliques ou parallèles par rapport aux âmes (4) si cela s'avérait nécessaire. It goes without saying that the invention is not limited to the embodiments described above by way of example, but on the contrary embraces all the variant embodiments. Thus the plate could comprise oblique or parallel cutouts with respect to the webs (4) if this were to prove necessary.
