Description

VITRAGE A PLATINE MULTIMATERIAU, PLATINE ET PROCEDE DE FABRICATION DU VITRAGEMULTI-MATERIAL PLATE GLAZING, PLATE AND METHOD FOR MANUFACTURING THE GLAZING Domaine de l’inventionField of the invention
La présente invention concerne un vitrage de véhicule comportant un élément vitré, au moins une platine présentant un corps en matière plastique (éventuellement renforcée) pour l’attachement réversible d’un accessoire audit élément vitré, ladite platine présentant une face extérieure qui est fixée en vis-à-vis d’une face intérieure dudit élément vitré, et comportant au moins une embase pour l’attachement réversible d’un autre accessoire, intérieur, audit élément vitré.The present invention relates to vehicle glazing comprising a glazed element, at least one plate having a body of plastic material (possibly reinforced) for the reversible attachment of an accessory to said glazed element, said plate having an exterior face which is fixed in facing an interior face of said glazed element, and comprising at least one base for the reversible attachment of another interior accessory to said glazed element.
La présente invention concerne ainsi une platine multifonction, le vitrage comportant cette platine afin de permettre l’attachement réversible de plusieurs accessoires et le procédé de fabrication du vitrage.The present invention thus relates to a multifunction plate, the glazing comprising this plate in order to allow the reversible attachment of several accessories and the method of manufacturing the glazing.
Etat de la techniqueState of the art
Il est connu de la demande internationale de brevet N° WO 2016/177955 de réaliser un vitrage avec au moins un bras de liaison liant une embase à une platine pour permettre de modifier l’orientation de l’embase vis-à-vis de la platine lors de la fixation de l’embase à la face intérieure de l’élément vitré.It is known from international patent application No. WO 2016/177955 to produce glazing with at least one connecting arm linking a base to a plate to make it possible to modify the orientation of the base with respect to the plate when fixing the base to the interior face of the glazed element.
Une embase peut être en particulier un système d’attachement réversible permettant à la fois d’attacher un capteur, comme par exemple un capteur de pluie, et un accessoire intérieur, comme par exemple un rétroviseur intérieur. La demande internationale de brevet N° WO 2013/039747 divulgue une telle embase.A base can in particular be a reversible attachment system allowing both a sensor, such as for example a rain sensor, and an interior accessory, such as for example an interior rear-view mirror to be attached. International patent application No. WO 2013/039747 discloses such a base.
Il est connu par ailleurs de la demande internationale de brevet N° WO 2018/206884 de réaliser une embase présentant un corps en matière plastique pour attacher de manière réversible un capteur et comportant une pièce métallique comportant une partie noyée à l’intérieur du corps de l’embase et une partie saillante intérieure. Ainsi, la partie saillante intérieure participe à une interface de fixation pour la fixation mécanique d’un accessoire intérieur et une coopération mécanique très élevée avec l’embase, permettant d’offrir une interface de fixation très forte.It is also known from international patent application No. WO 2018/206884 to produce a base having a plastic body for reversibly attaching a sensor and comprising a metal part comprising a part embedded inside the body of the base and an interior projecting part. Thus, the internal protruding part participates in a fixing interface for the mechanical fixing of an interior accessory and a very high mechanical cooperation with the base, making it possible to offer a very strong fixing interface.
L’art antérieur connaît aussi les demandes de brevets US 2014/0226012 et US 2020/361380.The prior art also includes patent applications US 2014/0226012 and US 2020/361380.
Un but de l’invention est de proposer une solution pour laquelle un vitrage comporte une embase permettant d’offrir une interface de fixation très forte tout en facilitant le positionnement et la fixation tant de l’embase que d’une platine adjacente à l’embase.An aim of the invention is to propose a solution for which a glazing comprises a base making it possible to offer a very strong fixing interface while facilitating the positioning and fixing of both the base and a plate adjacent to the base.
Ce but est atteint dans le cadre de la présente invention grâce à un vitrage de véhicule selon la revendication 1. Ce vitrage comporte un élément vitré, au moins une platine présentant un corps à base de matière plastique, ladite platine présentant une face extérieure qui est fixée en vis-à-vis d’une face intérieure dudit élément vitré, une face intérieure et un logement pour l’attachement réversible d’un accessoire audit élément vitré, ledit vitrage comportant au moins une embase pour l’attachement réversible d’un autre accessoire, intérieur, audit élément vitré, remarquable en ce que ladite embase est à base de matière plastique différente de celle dudit corps de la platine, la matière plastique du corps de ladite platine présente un module d’Young inférieur ou égal à 1 000 MPa et la matière plastique de ladite embase présente un module d’Young d’au moins 5 000 MPa, et en ce que ladite embase est fixée à ladite platine par moulage sur ladite platine ou ladite embase est lié mécaniquement par au moins un bras de liaison ou ladite embase est fixée à ladite platine par collage direct à ladite platine ou ladite embase est fixée à ladite platine par soudure, notamment par soudure ultrason.This goal is achieved in the context of the present invention thanks to vehicle glazing according to claim 1. This glazing comprises a glazed element, at least one plate having a body based on plastic material, said plate having an exterior face which is fixed opposite an interior face of said glazed element, an interior face and a housing for the reversible attachment of an accessory to said glazed element, said glazing comprising at least one base for the reversible attachment of a another accessory, interior, to said glazed element, remarkable in that said base is based on a plastic material different from that of said body of the plate, the plastic material of the body of said plate has a Young's modulus less than or equal to 1,000 MPa and the plastic material of said base has a Young's modulus of at least 5,000 MPa, and in that said base is fixed to said plate by molding on said plate or said base is mechanically linked by at least one arm of connection or said base is fixed to said plate by direct bonding to said plate or said base is fixed to said plate by welding, in particular by ultrasonic welding.
L’embase n’est pas attachée réversiblement à la platine ; par exemple l’embase n’est pas clipée sur la platine. Un attachement réversible n’est pas satisfaisant car il n’est pas suffisamment robuste pour une interface d’attachement réversible d’un accessoire intérieur.The base is not reversibly attached to the plate; for example the base is not clipped onto the plate. A reversible attachment is not satisfactory because it is not sufficiently robust for a reversible attachment interface of an interior accessory.
La présente invention est avantageusement complétée par les caractéristiques suivantes, prises individuellement ou en l’une quelconque de leurs combinaisons techniquement possibles :
- la matière plastique du corps de ladite platine présente un module d’Young compris entre 10 et 1 000 MPa et la matière plastique de ladite embase présente un module d’Young compris entre 5 000 et 20 000 MPa ; ainsi, la platine permet d’attacher correctement au moins un accessoire et l’embase permet d’attacher correctement au moins un accessoire intérieur.
- la matière plastique du corps de ladite platine et la matière plastique de ladite embase sont chacune à base de polyamide ; ainsi, la compatibilité entre les deux matière plastique est meilleure.
- ladite embase présente un pourtour qui est au moins pour la moitié de sa longueur, et de préférence la totalité de sa longueur, en vis-à-vis du corps de ladite platine ; ainsi, la liaison ou fixation de l’embase à la platine est plus élevée.
- ladite platine et ladite embase sont fixées à ladite face intérieure dudit élément vitré par une seule matière adhésive ; ainsi, la pièce unique est plus facile à installer.The present invention is advantageously supplemented by the following characteristics, taken individually or in any of their technically possible combinations:
- the plastic material of the body of said plate has a Young's modulus of between 10 and 1,000 MPa and the plastic material of said base has a Young's modulus of between 5,000 and 20,000 MPa; thus, the plate allows at least one accessory to be correctly attached and the base allows at least one interior accessory to be correctly attached.
- the plastic material of the body of said plate and the plastic material of said base are each based on polyamide; thus, the compatibility between the two plastic materials is better.
- said base has a periphery which is at least half of its length, and preferably all of its length, facing the body of said plate; thus, the connection or fixing of the base to the plate is higher.
- said plate and said base are fixed to said interior face of said glazed element by a single adhesive material; thus, the single piece is easier to install.
L’inventeur a ainsi découvert qu’une matière plastique à module d’Young bas, inférieur ou égal à 1 000 MPa (notamment compris entre 10 et 1 000 MPa), permettait d’attacher correctement au moins un accessoire à la platine, notamment un accessoire à visée optique vers l’extérieur et qu’une matière plastique à module d’Young élevé, d’au moins 5 000 MPa (notamment compris entre 5 000 et 20 000 MPa), permettait d’attacher correctement au moins un accessoire intérieur à l’embase et qu’il était important pour cela qu’une grande plage de module d’Young, ici de l’ordre d’au moins 4 000 MPa, sépare la valeur basse de la valeur élevée.The inventor thus discovered that a plastic material with a low Young's modulus, less than or equal to 1,000 MPa (in particular between 10 and 1,000 MPa), made it possible to correctly attach at least one accessory to the plate, in particular an accessory with optical sight towards the outside and that a plastic material with a high Young's modulus, of at least 5,000 MPa (in particular between 5,000 and 20,000 MPa), made it possible to correctly attach at least one accessory interior to the base and that it was important for this that a large range of Young's modulus, here of the order of at least 4,000 MPa, separates the low value from the high value.
Ladite embase comporte, de préférence, une interface d’attachement réversible d’un accessoire intérieur, comme par exemple par clipsage, ou par agrafage, ou par chaussage, ou par quart-de-tour et qui constitue de préférence une interface d’attachement réversible d’un pied de rétroviseur intérieur ou d’un écran de visualisation intérieur. Ladite embase comporte, de préférence, un logement pour la fixation d’un capteur, tel qu’un capteur de pluie.Said base preferably comprises a reversible attachment interface for an interior accessory, such as for example by clipping, or by stapling, or by slipping on, or by a quarter-turn and which preferably constitutes an attachment interface reversible of an interior mirror base or an interior display screen. Said base preferably comprises a housing for fixing a sensor, such as a rain sensor.
Dans une première variante, ladite embase est fixée à ladite platine par moulage sur ladite platine.In a first variant, said base is fixed to said plate by molding on said plate.
Dans une deuxième variante, ladite embase est liée mécaniquement par au moins un bras de liaison.In a second variant, said base is mechanically linked by at least one connecting arm.
Dans une troisième variante, ladite embase est fixée à ladite platine par collage direct à ladite platine (avec apport de colle) ; ladite embase est ainsi collée directement à ladite platine.In a third variant, said base is fixed to said plate by direct bonding to said plate (with addition of glue); said base is thus glued directly to said plate.
Dans une quatrième variante, ladite embase est fixée à ladite platine par soudure de matière plastique, notamment par soudure ultrason (sans apport de matière) ; ladite embase est ainsi soudée directement à ladite platine.In a fourth variant, said base is fixed to said plate by welding plastic material, in particular by ultrasonic welding (without adding material); said base is thus welded directly to said plate.
Ladite embase est, de préférence, séparée de ladite platine par une fente et cette fente est traversée ou enjambée par ledit ou lesdits bras de liaison, ledit ou lesdits bras de liaison étant, de préférence, dans la même matière plastique que le corps de ladite platine.Said base is, preferably, separated from said plate by a slot and this slot is crossed or spanned by said connecting arm or arms, said connecting arm or arms being, preferably, in the same plastic material as the body of said platinum.
Ledit ou lesdits bras de liaison pénètre(nt), de préférence, dans une cavité présentant une section identique et ménagée dans ladite embase afin de réaliser une liaison mécanique.Said connecting arm(s) preferably penetrate(s) into a cavity having an identical section and formed in said base in order to produce a mechanical connection.
Ladite embase est, de préférence, liée mécaniquement à ladite platine par plusieurs bras de liaison disposés de préférence symétriquement les uns par rapport aux autres et par rapport à un axe passant par un centre de ladite embase ou par rapport à un plan passant par un centre de ladite embase.Said base is, preferably, mechanically linked to said plate by several connecting arms preferably arranged symmetrically with respect to each other and with respect to an axis passing through a center of said base or with respect to a plane passing through a center of said base.
Un autre aspect de l’invention est une pièce pour la fixation de plusieurs accessoires au vitrage selon l’invention, ladite pièce comportant au moins une platine présentant un corps à base de matière plastique, ladite platine présentant une face extérieure, une face intérieure et un logement pour l’attachement réversible d’un accessoire, ladite pièce comportant au moins une embase pour l’attachement réversible d’un autre accessoire, intérieur, ladite pièce étant remarquable en ce que ladite embase est à base de matière plastique différente de celle dudit corps de la platine, la matière plastique du corps de ladite platine présente un module d’Young inférieur ou égal à 1 000 MPa et la matière plastique de ladite embase présente un module d’Young d’au moins 5 000 MPa, et en ce que ladite embase est fixée à ladite platine par moulage sur ladite platine ou ladite embase est lié mécaniquement par au moins un bras de liaison ou ladite embase est fixée à ladite platine par collage direct à ladite platine (avec apport de colle) ou ladite embase est fixée à ladite platine par soudure, notamment par soudure ultrason (sans apport de matière).Another aspect of the invention is a part for fixing several accessories to the glazing according to the invention, said part comprising at least one plate having a body based on plastic material, said plate having an exterior face, an interior face and a housing for the reversible attachment of an accessory, said part comprising at least one base for the reversible attachment of another interior accessory, said part being remarkable in that said base is based on a plastic material different from that of said body of the plate, the plastic material of the body of said plate has a Young's modulus less than or equal to 1,000 MPa and the plastic material of said base has a Young's modulus of at least 5,000 MPa, and in that said base is fixed to said plate by molding on said plate or said base is mechanically linked by at least one connecting arm or said base is fixed to said plate by direct bonding to said plate (with addition of glue) or said base is fixed to said plate by welding, in particular by ultrasonic welding (without adding material).
Un autre aspect de l’invention est un procédé de fabrication d’un vitrage selon l’invention, ledit vitrage comportant un élément vitré, une platine présentant un corps à base de matière plastique, ladite platine présentant une face extérieure, une face intérieure et un logement pour l’attachement réversible d’un accessoire audit élément vitré et une embase pour l’attachement réversible d’un autre accessoire, intérieur, audit élément vitré, ladite platine et ladite embase étant fabriqués séparément, ledit procédé étant remarquable en ce que ladite embase est à base de matière plastique différente de celle d’un corps de la platine, la matière plastique du corps de ladite platine présente un module d’Young inférieur ou égal à 1 000 MPa et la matière plastique de ladite embase présente un module d’Young d’au moins 5 000 MPa, et en ce que ladite embase est fixée à ladite platine par moulage sur ladite platine ou ladite embase est lié mécaniquement par au moins un bras de liaison ou ladite embase est fixée à ladite platine par collage direct à ladite platine (avec apport de colle lors du collage) ou ladite embase est fixée à ladite platine par soudure, notamment par soudure ultrason (sans apport de matière lors du collage).Another aspect of the invention is a method of manufacturing glazing according to the invention, said glazing comprising a glazed element, a plate having a body based on plastic material, said plate having an exterior face, an interior face and a housing for the reversible attachment of an accessory to said glazed element and a base for the reversible attachment of another interior accessory to said glazed element, said plate and said base being manufactured separately, said method being remarkable in that said base is based on a plastic material different from that of a body of the plate, the plastic material of the body of said plate has a Young's modulus less than or equal to 1,000 MPa and the plastic material of said base has a modulus of Young of at least 5,000 MPa, and in that said base is fixed to said plate by molding on said plate or said base is mechanically linked by at least one connecting arm or said base is fixed to said plate by gluing directly to said plate (with addition of glue during bonding) or said base is fixed to said plate by welding, in particular by ultrasonic welding (without addition of material during bonding).
Avantageusement, il n’y a qu’un seul composant (ou une seule pièce) qui est fixé(e) à l’élément vitré puisque la platine et l’embase ne font qu’un élément ; il n’y a donc qu’une seule référence à prendre pour positionner correctement le mono-composant platine-embase ; il ne peut pas y avoir de déviation dans la position de l’une par rapport à l’autre dans une série de vitrage.Advantageously, there is only one component (or one part) which is fixed to the glazed element since the plate and the base are only one element; there is therefore only one reference to take to correctly position the single-component plate-base; there cannot be any deviation in the position of one relative to the other in a series of glazing.
Avantageusement, tous les accessoires peuvent être correctement attaché, d’une manière réversible, à la pièce unique, y compris au moins un accessoire intérieur.Advantageously, all accessories can be correctly attached, in a reversible manner, to the single piece, including at least one interior accessory.

DéfinitionsDefinitions
Par « attache » ou « attachement » au sens de la présente invention, il faut comprendre les attaches mécaniques, qui s’attachent et se détachent manuellement ou à l’aide d’un outil mécanique. Ce qui est attaché est ainsi dans une position fixe. Par « fixation » au sens de la présente invention, il faut comprendre les fixations chimiques, qui engendrent des modifications moléculaires irréversibles, sauf à rompre la liaison et à rendre la platine inutilisable. Chacune de ces deux expressions exclut l’autre.By “fastener” or “attachment” within the meaning of the present invention, we must understand mechanical fasteners, which are attached and detached manually or using a mechanical tool. What is attached is thus in a fixed position. By “fixation” within the meaning of the present invention, it is necessary to understand chemical fixations, which generate irreversible molecular modifications, unless the bond is broken and the platinum becomes unusable. Each of these two expressions excludes the other.
Les termes « intérieur », « extérieur », s’entendent en qualifiant des parties du support considérées dans la position d’installation du support dans sa destination finale, c’est-à-dire fixé contre une face intérieure d’un élément vitré d’un vitrage de véhicule lui-même installé dans une baie de carrosserie du véhicule, le terme « intérieur » qualifiant une partie faisant face vers l’intérieur du véhicule tandis que « extérieur » qualifie une partie en vis-à-vis de l’extérieur du véhicule.The terms "interior", "exterior", are understood by qualifying parts of the support considered in the installation position of the support in its final destination, that is to say fixed against an interior face of a glazed element of vehicle glazing itself installed in a body bay of the vehicle, the term "interior" describing a part facing the interior of the vehicle while "exterior" describes a part facing the exterior of the vehicle.
La notion de « à base de matière plastique » signifie que le constituant essentiel du matériau constituant l’élément (l’embase) est de la matière plastique ; elle vise à couvrir que cette matière plastique peut être renforcée, par exemple en y mélangeant des fibres de renforts et notamment des fibres de verre ; mais exclut que le matériau constituant l’élément (l’embase) soit en lui-même métallique, c’est-à-dire en métal ou en alliage métallique.The notion of “plastic-based” means that the essential constituent of the material constituting the element (the base) is plastic; it aims to cover that this plastic material can be reinforced, for example by mixing reinforcing fibers and in particular glass fibers; but excludes that the material constituting the element (the base) is in itself metallic, that is to say made of metal or a metallic alloy.
L’embase doit permettre d’attacher réversiblement à un élément vitré au moins un accessoire particulier, appelé « accessoire intérieur » car accessible à un usager du véhicule (usager situé à l’intérieur du véhicule) ; il s’agit d’un accessoire utile et utilisé directement par un usager du véhicule et en particulier un miroir intérieur destiné à la vision du conducteur vers l’arrière du véhicule, appelé « rétroviseur », ou encore un écran de visualisation intérieur, par exemple destiné au même but. L’action de l’usager directement sur l’accessoire intérieur peut en particulier être une action de modification de l’orientation dans l’espace intérieur de cet accessoire intérieur.The base must make it possible to reversibly attach to a glazed element at least one particular accessory, called "interior accessory" because it is accessible to a user of the vehicle (user located inside the vehicle); it is a useful accessory used directly by a user of the vehicle and in particular an interior mirror intended for the driver's vision towards the rear of the vehicle, called a "rearview mirror", or even an interior display screen, for example example intended for the same purpose. The action of the user directly on the interior accessory can in particular be an action of modification of the orientation in the interior space of this interior accessory.
Un accessoire qui n’est pas dit « intérieur », n’est pas utilisé directement par un usager du véhicule, à l’intérieur du véhicule ; cet usager peut éventuellement avoir la possibilité de commander son fonctionnement (marche/arrêt) par l’intermédiaire d’une commande séparée mais il n’a pas d’action directe sur cet accessoire.An accessory that is not called “interior” is not used directly by a user of the vehicle, inside the vehicle; this user may possibly have the possibility of controlling its operation (on/off) via a separate command but he has no direct action on this accessory.
Description détaillée de l’inventionDetailed description of the invention
Architecture générale vitrageGeneral glazing architecture
En référence à la , un vitrage 1’ de l’art antérieur comprend un élément vitré 2 et au moins une platine 3’ pour l’attachement réversible d’un accessoire (non illustré) audit élément vitré 2, ladite platine 3’ une face extérieure 31 qui est fixée en vis-à-vis d’une face intérieure dudit élément vitré 2.In reference to the , a glazing 1' of the prior art comprises a glazed element 2 and at least one plate 3' for the reversible attachment of an accessory (not illustrated) to said glazed element 2, said plate 3' an exterior face 31 which is fixed opposite an interior face of said glazed element 2.
Le vitrage 1’ peut être choisi parmi un pare-brise, une lunette arrière, et un ensemble vitré latéral d'un véhicule. Le véhicule peut être une automobile, un train, et/ou un aéronef. En référence à la , le vitrage 1 est de préférence un pare-brise d'un véhicule automobile.The glazing 1' can be chosen from a windshield, a rear window, and a side glass assembly of a vehicle. The vehicle may be an automobile, a train, and/or an aircraft. In reference to the , the glazing 1 is preferably a windshield of a motor vehicle.
Le vitrage 1’ est destiné à fermer une baie réalisant une séparation entre un espace intérieur du véhicule et un espace extérieur au véhicule. L’élément vitré 2 présente ainsi une face extérieure 21 destinée à être tournée vers l’espace extérieur, une face intérieure, destinée à être tournée vers l’espace intérieur, ainsi qu’un chant périphérique 20.Glazing 1' is intended to close a window creating a separation between an interior space of the vehicle and a space exterior to the vehicle. The glazed element 2 thus has an exterior face 21 intended to face the exterior space, an interior face, intended to face the interior space, as well as a peripheral edge 20.
L’élément vitré peut être monolithique, c’est-à-dire constitué d’une feuille de matière unique, ou être composite, c’est-à-dire constitué de plusieurs feuilles de matière entre lesquelles est insérée au moins une couche de matière adhérente dans le cas des vitrages/éléments vitrés feuilletés. La (ou les) feuille(s) de matière peut (ou peuvent) être minérale(s), notamment en verre, ou organique(s), notamment en matière plastique.The glazed element can be monolithic, that is to say made up of a single sheet of material, or be composite, that is to say made up of several sheets of material between which is inserted at least one layer of adhesive material in the case of laminated glazing/glazed elements. The sheet(s) of material may be mineral(s), particularly glass, or organic, notably plastic.
L’élément vitré 2 présente un bord longitudinal 23, bas, un bord latéral 24, gauche, un bord longitudinal 25, haut et un bord latéral 26, droit. Les notions de « gauche » et « droit » sont ici en référence à l’axe central d’avancé du véhicule.The glazed element 2 has a bottom longitudinal edge 23, a left side edge 24, a top longitudinal edge 25 and a right side edge 26. The notions of “left” and “right” are here in reference to the central axis of forward movement of the vehicle.
Dans le cas d’un vitrage pour véhicule, le vitrage présente généralement au moins partiellement à sa périphérie, tout autour du bord de la face intérieure, une bande d’ornementation 4. Cette bande d’ornementation résulte en général d’un dépôt d’émail, réalisé sur la face intérieure de l’élément vitré lorsqu’il est monolithique ou sur une face intercalaire du vitrage pour les vitrages composites, mais elle peut également résulter d’une coloration partielle et/ou périphérique d’une feuille de matière utilisée, notamment d’une feuille en matière organique.In the case of glazing for a vehicle, the glazing generally presents at least partially at its periphery, all around the edge of the interior face, an ornamentation band 4. This ornamentation band generally results from a deposition of enamel, made on the interior face of the glazed element when it is monolithic or on an intermediate face of the glazing for composite glazing, but it can also result from partial and/or peripheral coloring of a sheet of material used, in particular a sheet of organic material.
Lorsque l’élément vitré est en matière organique, il a été fabriqué préalablement à la mise en œuvre de l’invention par moulage de la matière constitutive de l’élément vitré dans un dispositif de moulage comportant un moule comportant au moins une partie fixe de moule et une partie mobile de moule qui est mobile par rapport à la partie fixe de moule, lesdites parties de moule coopérant à l’état fermé du moule, pendant l’étape de moulage, pour former une cavité de moulage présentant en coupe la forme en coupe de l’élément vitré. Souvent, l’élément vitré en matière organique n’est pas plat mais bombé.When the glazed element is made of organic material, it has been manufactured prior to the implementation of the invention by molding the material constituting the glazed element in a molding device comprising a mold comprising at least one fixed part of mold and a movable mold part which is movable relative to the fixed mold part, said mold parts cooperating in the closed state of the mold, during the molding step, to form a molding cavity having the shape in section in section of the glazed element. Often, the glazed element made of organic material is not flat but curved.
Lorsque l’élément vitré est en matière minérale, il a été fabriqué préalablement à la mise en œuvre de l’invention par fusion de matière minérale en une feuille plate, puis par découpe de cette feuille et éventuellement bombage et/ou trempe de cette feuille.When the glazed element is made of mineral material, it was manufactured prior to the implementation of the invention by melting mineral material into a flat sheet, then by cutting this sheet and possibly bending and/or quenching this sheet .
Lorsque l’élément vitré est un élément vitré composite, il a été fabriqué selon la technique bien connue de fabrication des vitrages multiples ou des vitrages feuilletés, bombés.When the glazed element is a composite glazed element, it has been manufactured using the well-known technique of manufacturing multiple glazing or laminated, curved glazing.
Sur la , l’élément vitré 2 est un vitrage feuilleté, bombé. C’est ici un pare-brise d’un véhicule automobile.On the , the glazed element 2 is a laminated, curved glazing. This is a windshield of a motor vehicle.
La platine 3’ comporte d’une part une face extérieure 31 destinée à être tournée vers l’espace extérieur et qui est destinée à être fixée indirectement à une face intérieure de l’élément vitré en vis-à-vis de cette face intérieure de l’élément vitré et d’autre part une face intérieure, destinée à être tournée vers l’espace intérieur.The plate 3' comprises on the one hand an exterior face 31 intended to be turned towards the exterior space and which is intended to be fixed indirectly to an interior face of the glazed element facing this interior face of the glazed element and on the other hand an interior face, intended to be turned towards the interior space.
La platine 3’ comporte un logement 33 pour l’attachement réversible d’un accessoire à visée optique vers l’extérieur à l’élément vitré 2. Ce logement présente au moins un trou 30 pour le passage d’une partie d’un accessoire à visée optique vers l’extérieur, qui pourra ainsi être orientée en direction de l’extérieur.The plate 3' includes a housing 33 for the reversible attachment of an accessory with optical sighting towards the outside to the glazed element 2. This housing has at least one hole 30 for the passage of a part of an accessory with optical sight towards the outside, which can thus be oriented in the direction of the outside.
En référence aux figures 2 à 4, deux moyens d’attachement réversible d’accessoires de l’art antérieur sont illustrés. Ces moyens sont fixés contre la face intérieure d’un élément vitré (non illustré sur cette figure), afin que chacun permette l’attachement d’un accessoire.With reference to Figures 2 to 4, two means of reversible attachment of prior art accessories are illustrated. These means are fixed against the interior face of a glazed element (not illustrated in this figure), so that each allows the attachment of an accessory.
Ces deux moyens sont, ici, respectivement :
- une platine 3’ pour l’attachement réversible d’un accessoire à visée optique vers l’extérieur ou de plusieurs accessoires à visée optique vers l’extérieur, comme par exemple une caméra, à l’élément vitré, la platine 3’ présentant une face extérieure 31’ qui est destinée à être fixée à une face intérieure d’un élément vitré, en vis-à-vis de cette face intérieure de l’élément vitré ;
- une embase 5’ pour l’attachement réversible d’un autre accessoire, intérieur, et comportant une interface d’attachement 52 réversible par clipsage, ou par agrafage, ou par chaussage, ou par quart-de-tour et qui constitue de préférence une interface d’attachement réversible d’un pied de rétroviseur intérieur ou d’un écran de visualisation intérieur ; l’embase 5’ présentant une face extérieure 51 qui est destinée à être fixée à une face intérieure de l’élément vitré, en vis-à-vis de cette face intérieure de l’élément vitré.These two means are, here, respectively:
- a plate 3' for the reversible attachment of an accessory with optical sighting towards the outside or several accessories with optical sighting towards the outside, such as for example a camera, to the glazed element, the plate 3' having an exterior face 31' which is intended to be fixed to an interior face of a glazed element, facing this interior face of the glazed element;
- a base 5' for the reversible attachment of another interior accessory, and comprising an attachment interface 52 reversible by clipping, or by stapling, or by slipping on, or by a quarter turn and which preferably constitutes a reversible attachment interface for an interior mirror base or an interior display screen; the base 5' having an exterior face 51 which is intended to be fixed to an interior face of the glazed element, facing this interior face of the glazed element.
Ici la platine 3’ présente deux logements 33, 33’ pour l’attachement réversible de deux caméras, une de chaque côté d’un axe central de la platine qui coïncide avec l’axe central vertical du vitrage. Chaque logements 33, 33’ présente des éléments pour attacher et détacher une caméra, ainsi qu’un trou 64, 64’, qui traverse la platine sur son épaisseur et un obturateur incliné 66, 66’.Here the plate 3' has two housings 33, 33' for the reversible attachment of two cameras, one on each side of a central axis of the plate which coincides with the vertical central axis of the glazing. Each housing 33, 33' has elements for attaching and detaching a camera, as well as a hole 64, 64', which passes through the plate on its thickness and an inclined shutter 66, 66'.
Ici l’embase 5’ présente en outre un logement 53 pour l’attachement réversible d’un autre accessoire en son centre, comme par exemple un capteur de pluie, à l’élément vitré, ce logement présentant un trou 54 pour le passage d’une partie de cet accessoire.Here the base 5' also has a housing 53 for the reversible attachment of another accessory in its center, such as for example a rain sensor, to the glazed element, this housing having a hole 54 for the passage of 'part of this accessory.
Ces deux moyens (ou « composants » platine à double logement et embase à interface et à logement) sont indépendants les uns des autres : ils ne sont pas en contact direct l’un avec l’autre et il n’y a aucun élément de liaison mécanique entre eux.These two means (or "components" double housing plate and interface and housing base) are independent of each other: they are not in direct contact with each other and there is no element of mechanical connection between them.
Ces deux moyens sont fixés par leur face extérieure respective, 31, 51 à la face intérieure de l’élément vitré d’une manière indépendante :
- la platine 3’ est fixée à l’élément vitré par rapport à son référentiel qui lui est propre ;
- l’embase 5’ est fixée à l’élément vitré par rapport à son référentiel qui lui est propre et qui est indépendant de celui de la platine.These two means are fixed by their respective exterior faces, 31, 51 to the interior face of the glazed element in an independent manner:
- the plate 3' is fixed to the glazed element relative to its own frame of reference;
- the base 5' is fixed to the glazed element with respect to its own frame of reference and which is independent of that of the plate.
Ces deux moyens peuvent être fixés dans l’art antérieur par deux matières adhésives indépendantes à la face intérieure de l’élément vitré ; ils peuvent aussi être fixés par la même matière adhésive. Cette matière, ou ces matières, peut être, ou peuvent, être un ruban adhésif double face ou une colle.These two means can be fixed in the prior art by two independent adhesive materials to the interior face of the glazed element; they can also be fixed with the same adhesive material. This material, or these materials, may be, or may be, double-sided adhesive tape or glue.
Bien sûr, cette matière adhésive est disposée contre la face extérieure de la platine et de l’embase de telle sorte que les trous de chacun de ces deux moyens qui servent à attacher les accessoires ou à leur fonctionnement soient vides de matière adhésive.Of course, this adhesive material is placed against the exterior face of the plate and the base in such a way that the holes in each of these two means which are used to attach the accessories or to their operation are empty of adhesive material.
Ainsi, dans l’art antérieur, la platine 3’ et l’embase 5’ sont deux moyens distincts pour l’attachement réversible chacun d’un accessoire. La platine 3 présente un corps 30 généralement à base de matière plastique et l’embase 5’ est généralement en alliage métallique ou comporte une interface d’attachement réversible qui est métallique.Thus, in the prior art, the plate 3' and the base 5' are two distinct means for the reversible attachment each of an accessory. The plate 3 has a body 30 generally based on plastic material and the base 5' is generally made of a metal alloy or has a reversible attachment interface which is metallic.
L’embase 5’ est séparée de la platine 3’ par une fente 56 et cette fente n’est traversée par aucune matière, ni d’embase 5’, ni de platine 3’. Cette fente 56 pourrait être située tout autour de l’embase, mais comme l’embase est située le long d’un bord latéral de la platine, la fente ne fait pas tout le tour de l’embase.The 5' base is separated from the 3' plate by a slot 56 and this slot is not crossed by any material, neither the 5' base nor the 3' plate. This slot 56 could be located all around the base, but as the base is located along a side edge of the plate, the slot does not go all the way around the base.
Comme connu par ailleurs de la demande internationale de brevet N° WO 2016/177955, la platine 3’ et l’embase 5’ peuvent aussi être liés l’un à l’autre par au moins un bras de liaison, et de préférence plusieurs bras de liaison (en particulier deux, trois ou quatre bras) pour l’attachement réversible par chacun de ces moyens d’un accessoire tout en permettant de modifier/ajuster l’orientation de l’embase (et surtout de sa face extérieure 51) par rapport à la platine (et surtout sa face extérieure 31) par mouvement de l’embase qui est guidé et contrôlé par le, et de préférence les, bras de liaison 55.As is also known from international patent application No. WO 2016/177955, the plate 3' and the base 5' can also be linked to each other by at least one connecting arm, and preferably several connecting arms (in particular two, three or four arms) for the reversible attachment by each of these means of an accessory while allowing the modification/adjustment of the orientation of the base (and especially of its exterior face 51) relative to the plate (and especially its exterior face 31) by movement of the base which is guided and controlled by the, and preferably the, connecting arms 55.
Le vitrage 1 selon l’invention, illustré en , est similaire au vitrage 1’ de l’art antérieur illustré en figures 1 à 4 pour les références identiques mais diffère du vitrage 1’ de l’art antérieur illustré en figures 1 à 4 en ce qu’il comporte une l’embase 5 qui est à base de matière plastique différente de celle du corps 30 d’une platine 3 et en ce que :
- l’embase 5 est fixée à la platine 3 par moulage sur la platine 3, comme illustrée en figures 6 et 7, ou
- l’embase 5 est lié mécaniquement à la platine 3 par au moins un bras de liaison 55, comme illustrée en figures 8 et 9, ou
- l’embase 5 est fixée à la platine 3 par collage direct à la platine 3 en utilisant une colle, ou
- l’embase 5 est fixée à la platine 3 par soudure directe à la platine 3, par exemple par soudure utilisant des ultrasons.The glazing 1 according to the invention, illustrated in , is similar to the glazing 1' of the prior art illustrated in Figures 1 to 4 for identical references but differs from the glazing 1' of the prior art illustrated in Figures 1 to 4 in that it includes a base 5 which is based on a plastic material different from that of the body 30 of a plate 3 and in that:
- the base 5 is fixed to the plate 3 by molding on the plate 3, as illustrated in Figures 6 and 7, or
- the base 5 is mechanically linked to the plate 3 by at least one connecting arm 55, as illustrated in Figures 8 and 9, or
- the base 5 is fixed to the plate 3 by direct bonding to the plate 3 using glue, or
- the base 5 is fixed to the plate 3 by direct welding to the plate 3, for example by welding using ultrasound.
En effet, l’inventeur a découvert qu’en réalisant une liaison mécanique ou une fixation chimique entre l’embase et la platine alors que ces deux éléments sont à base de matières plastiques différentes, il est possible à la fois de réaliser un ensemble monobloc (une seule pièce) facile à fixer en face intérieure de l’élément vitré et à la fois très résistant.Indeed, the inventor discovered that by making a mechanical connection or a chemical fixing between the base and the plate while these two elements are based on different plastic materials, it is possible to produce a single-piece assembly. (one piece) easy to attach to the inside of the glazed element and at the same time very resistant.
La matière plastique du corps de la platine 3 présente un module d’Young inférieur ou égal à 1 000 MPa, notamment compris entre 10 et 1 000 MPa, ou encore entre 100 et 900 MPa. La matière plastique de l’embase 5 présente un module d’Young d’au moins 5 000 MPa, notamment compris entre 5 000 et 20 000 MPa, ou encore entre 7 000 et 19 000 MPa.The plastic material of the body of plate 3 has a Young's modulus less than or equal to 1,000 MPa, in particular between 10 and 1,000 MPa, or between 100 and 900 MPa. The plastic material of base 5 has a Young's modulus of at least 5,000 MPa, in particular between 5,000 and 20,000 MPa, or between 7,000 and 19,000 MPa.
La matière plastique du corps de la platine 3 et la matière plastique de l’embase 5 peuvent être chacune à base de polyamide. La platine 3 peut par exemple à base de, ou en, polyamide, comme par exemple à base de ou en PA66 ; elle peut être par exemple en PA66/PBT (PBT pour : polytéréphtalate de butylène) qui présente un module d’Young de l’ordre de 700 MPa. L’embase 5 peut par exemple être en PA6I/6T GF50, qui une matière plastique validée pour la fixation d’un rétroviseur intérieur et présentant un module d’Young de l’ordre de 17 GPa ; la platine ne peut pas être en PA6I/6T GF50 car cette matière est très trop rigide. The plastic material of the body of plate 3 and the plastic material of base 5 can each be based on polyamide. Plate 3 may for example be based on, or made of, polyamide, such as for example based on or made of PA66; it can for example be made of PA66/PBT (PBT for: polybutylene terephthalate) which has a Young's modulus of around 700 MPa. Base 5 can for example be made of PA6I/6T GF50, which is a plastic material validated for fixing an interior rear-view mirror and having a Young's modulus of around 17 GPa; the plate cannot be made of PA6I/6T GF50 because this material is too rigid.
Toutefois, la platine 3 peut par exemple à base de, ou en : Polycarbonate (PC), polybutylène téréphtalate (PBT), acrylonitrile butadiène styrène (ABS), acrylonitrile styrène acrylate (ASA) ; elle peut être par exemple en PC/PBT ou encore en PBT/ASA. La matière plastique du corps de la platine 3 et la matière plastique de l’embase 5 peuvent être chacune chargée, par exemple de fibre de verre ou de billes de verre.However, platinum 3 may for example be based on, or made of: Polycarbonate (PC), polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA); it can be for example in PC/PBT or even in PBT/ASA. The plastic material of the body of plate 3 and the plastic material of base 5 can each be loaded, for example with fiberglass or glass beads.
La platine 3 et l’embase 5 sont ici fixées ensemble à la face intérieure de l’élément vitré 2 par une seule matière adhésive. Plate 3 and base 5 are here fixed together to the interior face of glazed element 2 by a single adhesive material.
L’embase 5 présente ici un pourtour 50 qui est en vis-à-vis du corps 30 de la platine 3 le long de la totalité de sa longueur ; toute la périphérie de l’embase 5 est donc en vis-à-vis du corps 30 de la platine 3. Toutefois, le pourtour 50 pourrait être en vis-à-vis du corps 30 selon la moitié de sa longueur, voire plus.The base 5 here has a periphery 50 which is opposite the body 30 of the plate 3 along its entire length; the entire periphery of base 5 is therefore facing body 30 of plate 3. However, the periphery 50 could be facing body 30 along half its length, or even more.
Dans une première variante de réalisation de l’invention, illustrée en figures 6 et 7, l’embase 5 est fixée à la platine 3 par moulage sur la platine 3.In a first alternative embodiment of the invention, illustrated in Figures 6 and 7, the base 5 is fixed to the plate 3 by molding on the plate 3.
Dans cette première variante, il n’y a pas de fente entre la platine 3 et l’embase 5 ; l’embase 5 n’est pas venue de matière avec la platine 3 puisque la matière plastique qui les constitue est différente mais les deux éléments sont en contact direct l’un avec l’autre. Il peut éventuellement y avoir un ou plusieurs petits trous 57 entre la platine 3 et l’embase 5. Plus le pourtour 50 est en vis-à-vis du corps 30 de la platine 3, meilleure est la fixation de l’embase 5 à la platine 3.In this first variant, there is no slot between plate 3 and base 5; base 5 did not come from material with plate 3 since the plastic material which constitutes them is different but the two elements are in direct contact with each other. There may possibly be one or more small holes 57 between plate 3 and base 5. The more the perimeter 50 is opposite the body 30 of plate 3, the better the fixing of base 5 to deck 3.
Dans une deuxième variante de réalisation de l’invention, illustrée en figures 8 et 9, l’embase 5 est l’embase 5 est lié mécaniquement à la platine 3 par au moins un bras de liaison 55, et de préférence plusieurs bras de liaison (en particulier deux, trois ou quatre bras). Plus il y a de bras de liaison 55, meilleure est la fixation de l’embase 5 à la platine 3.In a second alternative embodiment of the invention, illustrated in Figures 8 and 9, the base 5 is the base 5 is mechanically linked to the plate 3 by at least one connecting arm 55, and preferably several connecting arms (in particular two, three or four arms). The more connecting arms 55 there are, the better the fixing of the base 5 to the plate 3.
Dans cette deuxième variante, l’embase 5 est séparée de la platine 3 par une fente 56 et cette fente est traversée ou enjambée par ledit ou lesdits bras de liaison 55, chaque bras de liaison 55 étant ici, dans la même matière plastique que la platine 3.In this second variant, the base 5 is separated from the plate 3 by a slot 56 and this slot is crossed or spanned by said connecting arm or arms 55, each connecting arm 55 being here, in the same plastic material as the platinum 3.
De préférence par ailleurs, ledit bras de liaison ou chaque bras de liaison est venu de matière d’une part avec ladite platine et d’autre part fixé ou attaché à l’embase, ledit bras de liaison ou chaque bras de liaison présentant de préférence :
- une largeur mesurée transversalement à ladite fente, comprise entre plus que 3,0 et 10,0 mm et/ou
- une épaisseur comprise entre 0,5 et 3,0 mm.Preferably moreover, said link arm or each link arm is made integrally with said plate on the one hand and on the other hand fixed or attached to the base, said link arm or each link arm preferably having :
- a width measured transversely to said slot, between more than 3.0 and 10.0 mm and/or
- a thickness of between 0.5 and 3.0 mm.
De préférence, ledit bras de liaison ou chaque bras de liaison est rectiligne (non coudé), afin de permettre une liaison plus rigide entre l’embase et la platine.Preferably, said connecting arm or each connecting arm is rectilinear (not bent), in order to allow a more rigid connection between the base and the plate.
Le bras de liaison 55, ou lesdits bras de liaison 55, pénètre(nt) dans une cavité présentant une section identique et ménagée dans l’embase 5 afin de réaliser une liaison mécanique.The connecting arm 55, or said connecting arms 55, penetrate(s) into a cavity having an identical section and provided in the base 5 in order to produce a mechanical connection.
L’embase 5 est ici liée mécaniquement à la platine 3 par plusieurs bras de liaison 55 disposés symétriquement les uns par rapport aux autres et par rapport à un axe passant par un centre de l’embase 5 (ou centre du logement 53) ou par rapport à un plan passant par un centre de l’embase 5.The base 5 is here mechanically linked to the plate 3 by several connecting arms 55 arranged symmetrically with respect to each other and with respect to an axis passing through a center of the base 5 (or center of the housing 53) or by relative to a plane passing through a center of the base 5.
Par exemple la semelle et l’embase sont liées par trois bras de liaison disposés à 120 ° les uns des autres par rapport à un centre de l’embase, ou, comme illustré, par quatre bras de liaison 55 disposés symétriquement deux à deux par rapport à un plan de symétrie passant par un centre de l’embase, (par exemple à 90 ° les uns des autres par rapport à un centre de l’embase).For example, the sole and the base are linked by three connecting arms arranged at 120° from each other relative to a center of the base, or, as illustrated, by four connecting arms 55 arranged symmetrically two by two per relative to a plane of symmetry passing through a center of the base, (for example at 90° from each other relative to a center of the base).
Il est possible par ailleurs que la platine comporte des éléments pour l’attachement réversible d’un cache intérieur.It is also possible that the plate includes elements for the reversible attachment of an interior cover.
Le vitrage selon l’invention peut comprendre les accessoires qui sont attachés grâce à la platine et à l’embase.The glazing according to the invention may include accessories which are attached using the plate and the base.
