Description

Procédé de réalisation de fenêtres optiques et fenêtres optiques réalisées selon le procédé Method for producing optical windows and optical windows produced according to the method
La présente Invention concerne les procédés pour réaliser des fenêtres optiques, ainsi que les fenêtres réalisées par le procédé.The present invention relates to the methods for producing optical windows, as well as the windows produced by the method.
Actuellement, pour réaliser une fenêtre optique dans un support, on commence par rélllser, dans ce support, une découpe dont les dimensions sont sensiblement celles de la fenêtre à obtenir, puis à découper une plaque de matériau optique de dimensions légèrement supérieures à celles de la découpe, à réaliser des points d'appui solidaires dudit support sur le pourtour de ladite découpe et à positionner la plaque dans la découpe, sur lesdits points d'appui, puis à solidariser les bords de la plaque optique aux bords de la découpe, par exemple par de la celle ou par des joints notamment en caoutchouc. Ces moyens donnent de bons résultats mais ils présentent quand même un inconvénient majeur par le fait qu'ils ne permettent pas un changement aisé de la plaque quand elle est, par exemple, détériorée. De plus, ces plaques optiques peuvent, malgré tout, être enlevées sans grandes difficultés par des personnes comme des cambrioleurs qui veulent pénétrer dans une enceinte par une fenêtre telle que définie ci-avant.Currently, to make an optical window in a support, one begins by relllsering, in this support, a cut whose dimensions are substantially those of the window to be obtained, then cutting a plate of optical material of dimensions slightly greater than those of the cutting, to make support points integral with said support around the periphery of said cut and to position the plate in the cut, on said support points, then to secure the edges of the optical plate to the edges of the cut, by example by that or by seals including rubber. These means give good results but they nevertheless have a major drawback in that they do not allow an easy change of the plate when it is, for example, deteriorated. In addition, these optical plates can, despite everything, be removed without great difficulty by people like burglars who want to enter an enclosure through a window as defined above.
La présente invention a pour but de pallier les inconvénients mentionnés ci-dessus.The present invention aims to overcome the drawbacks mentioned above.
Plus précisément, la présente invention a pour objet un procédé pour réaliser une fenêtre optique dans un support, consistant: à réaliser une découpe dont les dimensions sont sensiblement celles de la fenêtre à obtenir, à découper une plaque de matériau optique de dimensions sensiblement égales à celles de ladite découpe, à réaliser des points d'appui solidaires dudit support sur le pourtour de ladite découpe, à positionner ladite plaque dans ladite découpe sur lesdits points d'appui, caractérisé par le fait qu'il consiste en outre à appliquer une pression différentielle de parc et d'autre d'au moins une portion de ladite plaque, la pression de valeur la plus élevée étant appliquée sur la face de ladite plaque opposée à celle qui repose sur lesdits points d'appui.More specifically, the subject of the present invention is a method for producing an optical window in a support, consisting in: making a cut whose dimensions are substantially those of the window to be obtained, cutting a plate of optical material of dimensions substantially equal to those of said cutout, to make support points integral with said support around the periphery of said cutout, to position said plate in said cutout on said support points, characterized in that it also consists in applying pressure park and other differential of at least a portion of said plate, the highest value pressure being applied on the face of said plate opposite to that which rests on said support points.
La présente invention a aussi pour objet une fenêtre optique réalisée en accord avec le procédé défini ci-dessus dans un support situé dans une atmosphère ayant une certaine valeur de pression, caractérisée par le fait qu'elle comporte : une découpe réalisée dans ledit support, des moyens pour réaliser au moins une chambre comportant une ouverture située sur une surface de référence, des moyens commandables pour obtenir une circulation de fluide dans ladite chambre, et une plaque optique ayant au moins une face dont au moins une portion de la surface est conforme à ladite surface de référence, ladite plaque étant positionnée sur les bords de ladite chambre afin de former une enceinte étanche, la valeur de la pression régnant à l'intérieur de ladite enceinte étant inférieure à celle de la pression de ladite atmosphère.The present invention also relates to an optical window produced in accordance with the method defined above in a support located in an atmosphere having a certain pressure value, characterized in that it comprises: a cutout made in said support, means for producing at least one chamber comprising an opening situated on a reference surface, controllable means for obtaining a circulation of fluid in said chamber, and an optical plate having at least one face of which at least a portion of the surface conforms at said reference surface, said plate being positioned on the edges of said chamber in order to form a sealed enclosure, the value of the pressure prevailing inside said enclosure being less than that of the pressure of said atmosphere.
D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description suivante donnée en regard des dessins annexés à titre illustratif mais nullement limitatif dans lesquels:Other characteristics and advantages of the present invention will appear during the following description given with reference to the drawings annexed by way of illustration but in no way limitative in which:
- la figure 1 est une vue en perspective éclatée d'une fenêtre optique selon l'invention,FIG. 1 is an exploded perspective view of an optical window according to the invention,
- la figure 2 est une vue en coupe référencée II-II sur la figure 1,FIG. 2 is a sectional view referenced II-II in FIG. 1,
- la figure 3 représente un mode de réalisation d'une fenêtre optique dans une application comme pare-brise d'un véhicule automobile.- Figure 3 shows an embodiment of an optical window in an application as a windshield of a motor vehicle.
Le procédé pour réaliser une fenêtre optique dans un support consiste à réaliser une découpe dont les dimensions sont sensiblement celles de la fenêtre à obtenir, à découper une plaque de matériau optique de dimensions sensiblement égales à celles de la découpe, à réaliser des points d'appui solidaires du support sur le pourtour de la découpe, à positionner la plaque dans la découpe sur les points d'appui et enfin a appliquer une pression différentielle de part et d'autre d'au moins une portion de la plaque optique, la pression de valeur la plus élevée étant appliquée sur la face de la plaque opposée à celle qui repose sur les points d'appui.The method for producing an optical window in a support consists in making a cut whose dimensions are substantially those of the window to be obtained, in cutting a plate of optical material of dimensions substantially equal to those of the cut, in making points of support integral with the support on the periphery of the cutout, to position the plate in the cutout on the support points and finally to apply a differential pressure on either side of at least a portion of the optical plate, the pressure of the highest value being applied to the face of the plate opposite to that which rests on the support points.
Dans un mode avantageux de mise en oeuvre, le procédé selon l'invention trouve essentiellement une application à la réalisation d'une, fenêtre optique dans l'atmosphère terrestre où règne une pression de fluide importante et consiste alors en outre à réaliser une enceinte étanche par coopération avec les points d'appui tels que définis ci-avant avec la face de la plaque qui repose sur eux, et à réaliser dans cette enceinte un vide au moins partiel par rapport à l'atmosphère ambiante.In an advantageous embodiment, the method according to the invention essentially finds application in the production of an optical window in the Earth's atmosphere where there is a high fluid pressure and then also consists in producing a sealed enclosure by cooperation with the support points as defined above with the face of the plate which rests on them, and in producing in this enclosure an at least partial vacuum with respect to the ambient atmosphere.
Dans ce cas, l'enceinte est réalisée par une chambre comportant une ouverture dont les bords sont situés sur une surface, la chambre étant solidaire du support de façon que la surface définie par les bords de l'ouverture soit sur celle que doit occuper la face de la plaque reposant sur les points d'appui, la plaque étant alors apte à reposer sur les bords de cette ouverture pour fermer la chambre et réaliser ainsi l'enceinte, les bords de cette ouverture formant les points d'appui.In this case, the enclosure is produced by a chamber comprising an opening whose edges are situated on a surface, the chamber being integral with the support so that the surface defined by the edges of the opening is on that which the occupancy must occupy. face of the plate resting on the support points, the plate then being able to rest on the edges of this opening to close the chamber and thus produce the enclosure, the edges of this opening forming the support points.
Les figures 1 et 2 représentent une mise en eouvre du procédé décrit ci-dessus dans le cas d'un pare-brise.Figures 1 and 2 show an implementation of the method described above in the case of a windshield.
Le montage du pare-brise comprend un cadrée avec des cavités (2)reliées à une valve (3). Sur ce cadre (1), est monté un joint^avec des trous (5) correspondant aux cavités. Le pare-brise(6)est posé sur le joint(4). On réalise le vide dans les cavités (2) ce qui provoque la tenue du pare-brise. Il peut être prévu un capteur comprenant un contact (7) inséré dans un circuit électrique d'alarme pour signaler toute diminution de la dépression dans les cavités du cadre.The mounting of the windshield comprises a square with cavities (2) connected to a valve (3). On this frame (1), is mounted a gasket ^ with holes (5) corresponding to the cavities. The windshield (6) is placed on the seal (4). There is a vacuum in the cavities (2) which causes the holding of the windshield. A sensor may be provided comprising a contact (7) inserted in an electrical alarm circuit to signal any reduction in the vacuum in the cavities of the frame.
Le montage et la fixation du pare-brise, d'une vitre ou d'un panneau vitré se fait par aspiration de l'air contenu dans la ou les cavités du cadre par l'intermédiaire des valves qui sont placées sur le cadre et du cδté intérieur au véhicule comportant un tel pare-brise. La pression s'exerçant sur la face (8) du pare-brise opposée à celle en contact avec le joint (4) par rapport à celle régnant dans les cavités permet de retenir fermement la vitre ou le pare-brise Sur le cadre (1). Le joint placé entre le cadre et la vitre, par exemple en caoutchouc, assure l'étanchéité des cavités et isole la vitre du cadre pour amortir ainsi les éventuelles vibrations pouvant se créer lorsque le véhicule circule sur toutes sortes de voies.The mounting and fixing of the windshield, of a window or of a glazed panel is done by suction of the air contained in the cavity or cavities of the frame by means of the valves which are placed on the frame and of the interior side of the vehicle comprising such a windshield. The pressure exerted on the face (8) of the windshield opposite to that in contact with the seal (4) relative to that prevailing in the cavities makes it possible to firmly retain the glass or the windshield On the frame (1 ). The seal placed between the frame and the glass, for example rubber, seals the cavities and insulates the glass from the frame to thereby dampen any vibrations that may be created when the vehicle is traveling on all kinds of tracks.
Il peut être bien entendu avantageux que le système comporte une pluralité de cavités(2) dans le cadre pour assurer plus de sécurité dans le cas d'une perte accidentelle d'étanchéité dans une des cavités. L'effet de ventouse des autres cavités retiendra fermement la vitre ou le pare-brise jusqu'à ce que la réparation nécessaire soit effectuée.It may of course be advantageous for the system to have a plurality of cavities (2) in the frame to provide more security in the event of an accidental loss of sealing in one of the cavities. The suction effect of other cavities will firmly hold the glass or windshield until the necessary repair is made.
La figure 3 représente, sous forme schématique, une mise en eouvre du procédé pour la réalisation d'un pare-brise (10)de voitureFIG. 3 represents, in diagrammatic form, an implementation of the method for producing a car windshield (10)
(11). Ce pare-brise est posé comme décrit ci-avant sur un conduit (l2) situé sur le pourtour (13) d'une découpe (l4j dans la carrosserie (15) de la voiture, cette découpe formant un cadre. Dans un mode avantageux, le conduit est constitué en un matériau élastiquement déformable et comporte en plus des pattes de fixation (16) en un matériau solide et rigide, au bord (13) de la découpe réalisée dans la carrosserie.(11). This windshield is placed as described above on a duct (12) located on the periphery (13) of a cutout (14j in the bodywork (15) of the car, this cutout forming a frame. , the conduit is made of an elastically deformable material and further comprises fixing lugs (16) of a solid and rigid material, at the edge (13) of the cutout made in the bodywork.
Ce conduit (12) définissant une chambre comporte au moins une ouverture(17) avantageusement. constituée par une pluralité d'ouvertures secondaires (18, 19) ... réalisées latéralement sur le conduit, de façon que leurs bords(20) soient situés sur une surface de référence(21) et que le pare-brise puisse alors être positionné sur ces ouvertures de façon que l'une de ses faces puisse former avec la chambre définie par le conduit une enceinte étanche(22).This duct (12) defining a chamber advantageously has at least one opening (17). constituted by a plurality of secondary openings (18, 19) ... made laterally on the duct, so that their edges (20) are located on a reference surface (21) and that the windshield can then be positioned on these openings so that one of its faces can form with the chamber defined by the conduit a sealed enclosure (22).
La fenêtre comporte aussi des moyens commandables(23) pour obtenir une circulation de fluide dans le conduit. Ces moyens comprennent une conduite(24) reliée de façon étanche à l'intérieur du conduit (12) et une valve (25) montée en série sur la conduite, l'extrémité (26) de la conduite opposée à celle (27) située à l'intérieur du conduit étant apte à être connectée, par exemple, à une pompe du type à vide.The window also includes controllable means (23) for obtaining fluid circulation in the conduit. These means include a pipe (24) tightly connected inside the pipe (12) and a valve (25) mounted in series on the pipe, the end (26) of the pipe opposite to that (27) located inside the duct being able to be connected, for example, to a vacuum type pump.
Comme mentionné ci-avant, la fenêtre optique comporte en outre des moyens (28, 29).. pour mesurer la valeur de la pression à l'intérieur du conduit et élaborer en sortie (30, 31)... un signal représentatif de cette valeur, et des moyens de traitement (32) dudit signal aptes à élaborer un signal de résultat pour commander, par exemple, des moyens d'alarme (33) du type sonore ou visuel, par exemple un avertisseur sonore tel qu'illustré sur la figure 3.As mentioned above, the optical window also comprises means (28, 29) .. for measuring the value of the pressure inside the duct and producing at the output (30, 31) ... a signal representative of this value, and processing means (32) of said signal capable of producing a result signal for controlling, for example, alarm means (33) of the audible or visual type, for example an audible warning as shown in Figure 3.
La perte d'étanchéité ou du vide partiel dans une cavité peut être due à deux facteurs majeurs, tentative de vol ou d'effraction du véhicule par dépose ou casse du pare-brise ou d'une des vitres, défectuosité des valves ou perte de souplesse-élasticité du joint.The loss of tightness or partial vacuum in a cavity can be due to two major factors, attempted theft or break-in of the vehicle by removing or breaking the windshield or one of the windows, faulty valves or loss of flexibility-elasticity of the joint.
Des contacts par dépression incorporés aux valves ou bien montés séparément sur le cadre seront reliés au système d'alarme qui sera activé en cas de perte de vide.Vacuum contacts incorporated into the valves or mounted separately on the frame will be connected to the alarm system which will be activated in the event of loss of vacuum.
Un autre mode de réalisation pour un avertisseur consiste à pourvoir les contacts de voyants qui, par exemple, tournent au rouge lorsque le vide dans les cavités ne sera pas suffisant pour créer l'effet de ventouse.Another embodiment for an alarm consists in providing the contacts with indicator lights which, for example, turn red when the vacuum in the cavities is not sufficient to create the suction cup effect.
Pour la préparation des voitures de compétition, ainsi que pour la pose des vitres en aviation, on utilise actuellement la technique du collage. Cette procédure est très coûteuse et prend beaucoup de temps. Elle est très risquée aussi dans la course automobile car, en cas d'accident, le pilote ou conducteur n'a parfois que la ressource de briser le pare-brise ou une des vitres de la voiture pour en sortir. Avec la réalisation proposée, les valves (25) peuvent être munies d'un système d'urgence (34), shématiquement représenté sur la figure 3 permettant de les ouvrir très rapidement, pour admettre de l'air dans les chambres afin d'égaliser la pression de chaque côté de la vitre et donc de pouvoir la désolidariser du cadre sans difficulté. Dans le domaine de la construction de bâtiments, le procédé décrit ci-dessus peut être utilisé, avec moins de sophistication, pour la pose-fixation des vitres aux cadres des fenêtres, ainsi que pour la pose des panneaux vitrés qui constituent les façades extérieures des bâtiments modernes. L'invention trouve également une application intéressante dans l'étude de nouvelles formes ou la recherche aérodynamique des carrosseries automobiles, des trains à grande vitesse, dans l'aéronautique, etc. Elle permet une automatisation et une robotisation complètes des poses de pare-brises, vitres fixes et panneaux vitrés. For the preparation of competition cars, as well as for the installation of windows in aviation, the bonding technique is currently used. This procedure is very expensive and time consuming. It is also very risky in motor racing because, in the event of an accident, the driver or driver sometimes has only the resource to break the windshield or one of the windows of the car to get out. With the proposed embodiment, the valves (25) can be provided with an emergency system (34), shown diagrammatically in FIG. 3 allowing them to be opened very quickly, to admit air into the chambers in order to equalize the pressure on each side of the glass and therefore to be able to separate it from the frame without difficulty. In the field of building construction, the process described above can be used, with less sophistication, for the installation-fixing of the panes to the window frames, as well as for the installation of the glazed panels which constitute the external facades of the modern buildings. The invention also finds an interesting application in the study of new forms or the aerodynamic research of automobile bodies, high-speed trains, in aeronautics, etc. It allows complete automation and robotization of the installation of windshields, fixed windows and glass panels.
