Description

La présente invention porte sur une installation réfrigérée comprenant un guichet ouvrant en verre. Des installations réfrigérées sont décrites par exemple dans les documents US 4586347 et US 5209082 , et sont telles qu'un réfrigérateur (ou même un congélateur, ou éventuellement toute installation réfrigérée de stockage, distribution, présentation, etc.). Le guichet permet d'accéder à une zone limitée de l'intérieur de l'installation sans avoir à ouvrir la porte de l'installation. De cette manière, les déperditions calorifiques qui se produisent lors de l'ouverture de la porte donnant accès à tout l'espace intérieur de l'installation sont limitées, car cette porte est moins souvent ouverte.The present invention relates to a refrigerated plant comprising a glass opening aperture. Refrigerated installations are described for example in the documents US 4586347 and US 5209082 , and are such as a refrigerator (or even a freezer, or possibly any refrigerated storage, distribution, presentation, etc.). The window allows access to a limited area of the interior of the installation without having to open the door of the installation. In this way, the heat losses that occur when opening the door giving access to the entire interior of the installation are limited because this door is less often open.

Les portes du réfrigérateur sont en effet très souvent ouvertes, et dans beaucoup de cas, pour y prélever seulement des boissons. Les grandes pertes de fraîcheur ainsi provoquées par ces ouvertures en grand fréquentes conduisent à dépenser plus d'énergie pour refroidir l'intérieur du réfrigérateur.The doors of the refrigerator are indeed very often open, and in many cases, to take only drinks. The large losses of freshness thus caused by these frequent openings lead to spending more energy to cool the interior of the refrigerator.

La présente invention a pour but de remédier à cet inconvénient en proposant une installation réfrigérée telle que définie en revendication 1. Cette installation comprend un guichet ouvrant dont l'intérêt est double : d'une part, plus petit que la porte du réfrigérateur, son ouverture limite fortement la perte de fraîcheur par rapport à l'ouverture de la porte du réfrigérateur ; et d'autre part, en verre, il permet de voir la zone limitée du réfrigérateur, utilisée par exemple pour stocker les boissons, et de ne pas l'ouvrir s'il ne contient pas la boisson désirée.The present invention aims to overcome this disadvantage by proposing a refrigerated installation as defined in claim 1. This installation comprises an opening window whose interest is double: on the one hand, smaller than the refrigerator door, its opening greatly limits the loss of freshness compared to the opening of the refrigerator door; and on the other hand, in glass, it allows to see the limited area of the refrigerator, used for example to store drinks, and not to open it if it does not contain the desired drink.

Par ailleurs, il est utile que ces guichets ouvrants ne conduisent pas à une condensation sur la paroi intérieure du guichet, notamment après ouverture, l'embuage résultant conduisant par ailleurs à mal voir ou à ne plus pouvoir voir la zone intérieure de l'installation réfrigérée. Egalement, la paroi extérieure du guichet ne doit pas être froide. Sous peine de condensation notamment, les contraintes sont ici assez strictes : ainsi, il faut qu'il n'y ait pas d'embuage ou condensation, ou givrage pour une température intérieure de l'installation réfrigérée n'excédant pas 0°C quand il s'agit d'un congélateur ou de l'ordre de 5°C quand il s'agit d'un réfrigérateur, avec 50% d'humidité, et pour une température extérieure de l'installation réfrigérée allant jusqu'à 38°C avec 85% d'humidité. Le guichet ouvrant ne doit par ailleurs généralement pas comporter de paroi fragile, par exemple rayable.Furthermore, it is useful that these opening windows do not lead to condensation on the inner wall of the window, especially after opening, the resulting mist also leading to poor visibility or not being able to see the interior area of the installation refrigerated. Also, the outer wall of the window should not be cold. Under penalty of condensation in particular, the constraints are here quite strict: thus, it is necessary that there is no fogging or condensation, or icing for an internal temperature of the refrigerated installation not exceeding 0 ° C when it is a freezer or the order of 5 ° C when it is a refrigerator, with 50% humidity, and for an outside temperature of the refrigerated installation up to 38 ° C with 85% humidity. The opening window must also generally have no fragile wall, for example scratchable.

Pour résoudre ces inconvénients, la présente invention a d'abord pour objet une installation telle que définie en revendication 1. Le vitrage est avantageusement un vitrage isolant.To overcome these drawbacks, the present invention firstly relates to an installation as defined in claim 1. The glazing is advantageously an insulating glazing unit.

Le vitrage utilisé pour composer le guichet ouvrant peut être un verre monolithique tel qu'un verre sodo - calcique, ledit verre pouvant être trempé, ou peut être en un polymère, tel que le poly(méthacrylate de méthyle), ou peut comporter plusieurs feuilles de verre et/ou de polymère(s) (vitrage multiple et/ou feuilleté), par exemple peut être ou comporter un verre feuilleté dans lequel une feuille de polyvinylbutyral ou de polyuréthanne ou autre, d'une épaisseur généralement comprise entre 0,3 et 2 mm, est prise en sandwich entre deux feuilles de verre.The glazing used to compose the opening window may be a monolithic glass such as a soda-lime glass, said glass may be tempered, or may be a polymer, such as poly (methyl methacrylate), or may comprise several sheets of glass and / or polymer (s) (multiple glazing and / or laminated glass), for example may be or comprise a laminated glass in which a sheet of polyvinyl butyral or polyurethane or other, of a thickness generally between 0.3 and 2 mm, is sandwiched between two sheets of glass.

Le vitrage , ou le cas échéant au moins l'une des feuilles formant le vitrage, peut comporter certaines décorations et/ou fonctionnalités (chauffage, éclairage, etc.). A titre d'exemples non exhaustifs, au moins une des feuilles constituant le vitrage peut être teintée ou colorée, revêtue de couche(s) fonctionnelle(s) (par exemple du type réfléchissant l'infra-rouge notamment à base d'argent, et/ou basse émissive , et/ou du type anti -givre, et/ou du type anti -salissures à base de TiO2 photocatalytique, etc.) et/ou revêtue de couche(s) esthétique(s), par exemple par sérigraphie ou émaillage (notamment en périphérie), peut comporter un revêtement doré ou argenté, peut être traitée (par exemple trempée), etc. Comme vitrage fonctionnel, on peut également citer comme exemple non exhaustif un vitrage feuilleté à fonctionnalité électrocommandée, du type vitrage apte à être soit transparent, soit opaque ou translucide sous l'effet d'un courant électrique (cas notamment d'un vitrage à cristaux liquides , tel qu'un vitrage de la marque Privalite® de la société Saint-Gobain).The glazing, or where appropriate at least one of the sheets forming the glazing, may include certain decorations and / or functionalities (heating, lighting, etc.). By way of non-exhaustive examples, at least one of the sheets constituting the glazing may be tinted or colored, coated with functional layer (s) (for example of the infra-red reflecting type, especially based on silver, and / or low emissivity, and / or of the anti-frost type, and / or of the anti-fouling type based on TiO 2 photocatalytic, etc.) and / or coated with aesthetic layer (s), for example by screen printing or enameling (especially in the periphery), may comprise a gold or silver coating, may be treated (for example tempered), etc. As functional glazing, one can also cite as non-exhaustive example a laminated glazing with electrocontrolled functionality, of the glazing type capable of being either transparent, or opaque or translucent under the effect of an electric current (in particular a crystal glazing liquids, such as Privalite® brand glass from Saint-Gobain).

Conformément à un mode de réalisation avantageux, le vitrage est un vitrage multiple, notamment un double vitrage (ou un triple vitrage, voire un vitrage comportant plus de 3 feuilles de verre, pour une isolation encore renforcée) à lame d'atmosphère intérieure préférentiellement épaisse, les feuilles de verre composant le vitrage multiple étant maintenues espacées avec emprisonnement de la ou des lames d'atmosphère intérieure par un espaceur périphérique, lequel constitue normalement le châssis ou un élément du châssis.According to an advantageous embodiment, the glazing is a multiple glazing, in particular a double glazing (or a triple glazing, or even a glazing comprising more than 3 sheets of glass, for an even stronger insulation) with preferably thick inner atmosphere blade , the glass sheets composing the multiple glazing being kept spaced with imprisonment of the inner atmosphere slats or blades by a peripheral spacer, which normally constitutes the frame or a frame member.

A titre d'exemple, le double vitrage ci -dessus peut comporter deux feuilles de verre de 3 ou 4 mm d'épaisseur et une lame d'atmosphère intérieure de 13 mm d'épaisseur.By way of example, the double glazing above may comprise two glass sheets 3 or 4 mm thick and an inner atmosphere plate 13 mm thick.

L'atmosphère entre deux lames de verre adjacentes peut être constituée par exemple par de l'air, ou par un gaz rare tel que le krypton , l'argon, etc. , ou par un mélange de gaz rares.The atmosphere between two adjacent glass slides may be constituted for example by air, or by a rare gas such as krypton, argon, etc. , or by a mixture of rare gases.

Comme indiqué précédemment , le vitrage peut comporter des décorations et/ou fonctionnalités; en particulier, au moins une face d'une feuille du vitrage multiple, ou même au moins deux faces (notamment en regard) à l'intérieur du vitrage multiple, peuvent être revêtues par au moins une couche réfléchissant l'infrarouge, laquelle est avantageusement à base d'argent, déposée par une technique dite de pulvérisation cathodique ou sputtering par magnétron, étant par exemple constituée par des empilements de couches dans lesquelles une couche d'argent est prise en sandwich entre deux couches de diélectrique tel que l'oxyde d'étain (Sn02). On peut en particulier citer les couches Planitherm° de la Société Saint-Gobain.As indicated above, the glazing may comprise decorations and / or functionalities; in particular, at least one face of a sheet of the multiple glazing, or even at least two faces (especially facing) inside the multiple glazing, can be coated with at least one infrared reflecting layer, which is advantageously based on silver, deposited by a technique known as sputtering or magnetron sputtering, being for example constituted by stacks of layers in which a silver layer is sandwiched between two layers of dielectric such as the oxide of tin (SnO2). We can particularly mention the Planitherm ° layers of the Saint-Gobain Society.

L'espaceur périphérique entre deux feuilles de verre adjacentes peut être formé de profilés en aluminium, en acier, en matière plastique ou en matière plastique chargée par des fibres, lesdits profilés étant le cas échéant pliés aux angles du cadre ou coupés en tronçons rectilignes réunis par des pièces d'angle, les feuilles de verre étant maintenues contre les espaceurs par des couches de joint -colle d'étanchéité, par exemple en caoutchouc butyle, l'espaceur périphérique comportant en outre généralement une couche périphérique externe de polysulfure ou silicone appliquée contre son chant. Le choix d'une matière plastique pour les profilés de l'espaceur (tels que les profilés Swisspacer® de la Société Saint-Gobain) permet de réduire le pont thermique car la matière plastique est peu conductrice thermique ment. Il peut également s'agir d'un profilé plat collé sur la tranche des feuilles de verre, comme décrit dans les documents de brevets WO 04/035981 et WO 01/79644 .The peripheral spacer between two adjacent glass sheets may be formed of aluminum, steel, plastic or fiber-loaded plastic profiles, said profiles being optionally folded at the corners of the frame or cut into straight rectilinear sections. by corner pieces, the glass sheets being held against the spacers by seal-sealing layer layers, for example butyl rubber, the peripheral spacer furthermore generally comprising an outer peripheral layer of polysulfide or silicone applied against his singing. The choice of a plastic material for the spacer profiles (such as Swisspacer® profiles from the Saint-Gobain Company) makes it possible to reduce the thermal bridge because the plastics material is not very thermally conductive. It can also be a flat profile glued to the edge of the glass sheets, as described in the patent documents. WO 04/035981 and WO 01/79644 .

Le vitrage du guichet ouvrant de l'installation selon la présente invention est notamment choisi pour présenter un niveau d'isolation élevé tel que le coefficient U exprimé en watts/m2/°K soit au plus égal à 1,2, en particulier au plus égal à 1, étant notamment de 0,7.The window of the opening window of the installation according to the present invention is in particular chosen to have a high level of insulation such that the coefficient U expressed in watts / m2 / ° K is at most equal to 1.2, in particular at most equal to 1, being in particular 0.7.

Les éléments qui composent le guichet ouvrant sont ainsi avantageusement choisis pour que ce dernier soit capable de fonctionner sans embuage ni givrage pour des conditions intérieures de l'installation réfrigérée d'une température inférieure à 0°C ou d'une température de l'ordre de 5°C et d'un taux d'humidité aux environs de 50% et des conditions extérieures variées allant notamment d'une température aux environs de 20°C à des conditions tropicales de température aux environs de 38°C, et d'un taux d'humidité de 85%.The elements that make up the opening window are thus advantageously chosen so that the latter is able to operate without fogging or icing for indoor conditions of the refrigerated installation of a temperature below 0 ° C or a temperature of the order of 5 ° C and a humidity of around 50% and varied outdoor conditions ranging from a temperature around 20 ° C to tropical temperature of about 38 ° C, and a humidity level of 85%.

Le guichet ouvrant de l'installation selon l'invention peut être agencé pour être reçu de façon étanche dans l'ouverture de l'installation réfrigérée, avec interposition d'un joint d'étanchéité portée par celle-ci, des moyens magnétiques ou mécaniques pouvant être notamment utilisés pour consolider la fermeture.The opening window of the installation according to the invention can be arranged to be sealed in the opening of the refrigerated installation, with the interposition of a seal carried by it, magnetic or mechanical means which can be used in particular to consolidate the closure.

Le guichet ouvrant de l'installation selon l'invention peut également comporter une poignée de man oeuvre. Il peut être monté ouvrant à l'horizontale, des moyens pouvant être prévus pour retenir le châssis ouvert dans une position horizontale, à la manière d'un bar, ou peut également être monté ouvrant selon un autre axe, par exemple un axe vertical.The opening window of the installation according to the invention may also include a handle. It can be mounted opening horizontally, means that can be provided to retain the open frame in a horizontal position, in the manner of a bar, or can also be mounted opening on another axis, for example a vertical axis.

Conformément à une caractéristique particulière de la présente invention, le guichet ouvrant comporte un vitrage multiple dont la feuille la plus externe ou la plus interne en position de montage dépasse des autres feuilles, cette partie dépassante pouvant par exemple porter des lames rectangulaires de charnières d'articulation du guichet dont les autres lames sont portées par la structure de l'installation réfrigérée.According to a particular feature of the present invention, the opening window comprises a multiple glazing whose outermost or innermost sheet in the mounting position protrudes from the other sheets, this protruding part may for example carry rectangular hinge blades. articulation of the window whose other blades are carried by the structure of the refrigerated installation.

Conformément à une première variante, la feuille qui dépasse des autres feuilles est la feuille la plus externe, la structure de l'installation réfrigérée étant agencée pour permettre un encastrement du guichet en position fermée de celui -ci, les lames de charnières d'articulation étant par exemple disposées le long d'une bordure verticale ou d e la bordure horizontale, inférieure notamment, de ladite feuille de verre externe, et une poignée de manoeuvre étant fixée par exemple par collage le long de la bordure de ladite feuille externe opposée à celle portant les lames des charnières.According to a first variant, the sheet that protrudes from the other sheets is the outermost sheet, the structure of the refrigerated installation being arranged to allow a recess of the window in closed position thereof, the hinge hinge blades being arranged for example along a vertical edge or the horizontal rim, in particular lower, of said outer glass sheet, and a maneuvering handle being fixed for example by gluing along the edge of said outer sheet opposite to that carrying the blades of the hinges.

Conformément à une seconde variante, la feuille qui dépasse des autres feuilles est la feuille la plus interne, un cadre en matière plastique venant enserrer à force le châssis par son chant et comportant un rebord vers l'intérieur venant s'appliquer sur la face externe de la feuille de verre la plus externe en position d'utilisation, le cadre portant extérieurement la poignée de manoeuvre.According to a second variant, the sheet which protrudes from the other sheets is the innermost sheet, a frame of plastic material forcibly clamping the frame by its edge and having an inward rim coming to be applied on the outer face the outermost glass sheet in the use position, the frame externally carrying the operating handle.

Dans ce cas, les lames des charnières d'articulation peuvent être disposées le long d'une bordure verticale ou de la bordure horizontale, notamment inférieure, de ladite feuille de verre interne, ou le cadre peut porter des axes d'articulation du châssis sur la structure de l'installation réfrigérée.In this case, the blades of the hinge hinges can be arranged along a vertical edge or the horizontal rim, in particular lower, of said internal glass sheet, or the frame can carry hinge pins of the frame on the structure of the refrigerated plant.

L'installation réfrigérée peut également avantageusement comporter un bandeau en verre de commande de l'installation, par exemple de commande par boutons ou de commande de l'électronique et des afficheurs de l'électronique de commande de l'installation, ledit bandeau étant par exemple associé au guichet ouvant selon l'invention en étant disposé, généralement fixe, dans une région de la paroi ou de la porte comportant le guichet, au voisinage de celui-ci.The refrigerated installation may also advantageously comprise a control glass strip of the installation, for example control by buttons or control of the electronics and displays of the control electronics of the installation, said headband for example associated with the opening window according to the invention being disposed, generally fixed, in a region of the wall or door with the window in the vicinity thereof.

  • the Figure 6 is a front view of the glass band that can be seen on the Figure 1 above opening window that carries the control electronics and displays of the refrigerator control electronics.

Si l'on se réfère aux Figures 1 à 3, on peut voir que l'on a représenté schématiquement en traits mixtes la partie supérieure d'un réfrigérateur 1 dont la porte 2 comporte, dans cette partie supérieure, une ouverture rectangulaire 3 apte à être fermée hermétiquement par un guichet en verre 4, lequel permet donc un accès limité au compartiment interne du réfrigérateur.If we refer to Figures 1 to 3 , it can be seen that is shown schematically in phantom the upper part of a refrigerator 1 whose door 2 comprises, in this upper part, a rectangular opening 3 adapted to be sealed by a glass window 4, which therefore allows limited access to the internal compartment of the refrigerator.

Dans l'exemple représenté, cette ouverture s'étend sur une majeure partie de la largeur de la porte du réfrigérateur, ses petits côtés étant parallèles aux bordures verticales du réfrigérateur 1.In the example shown, this opening extends over a major part of the width of the refrigerator door, its short sides being parallel to the vertical edges of the refrigerator 1.

Le guichet 4 consiste en un châssis de double vitrage comportant deux feuilles de verre 5, 6, destinées à venir se positionner respectivement à l'intérieur et à l'extérieur du réfrigérateur 1 en position de montage du guichet 4, et maintenues écartées par un espaceur consistant en un cadre rectangulaire périphérique 7 auquel elles sont collées comme décrit ci -après, avec interposition d'une lame de gaz 8.The window 4 consists of a double-glazed frame comprising two glass sheets 5, 6 intended to be positioned respectively inside and outside the refrigerator 1 in the mounting position of the window 4, and kept apart by a spacer consisting of a rectangular peripheral frame 7 to which they are glued as described below, with the interposition of a gas blade 8.

La feuille de verre extérieure 6 est plus grande que la feuille de verre intérieure 5 et dépasse de celle -ci sur tout son pourtour, avec des largeurs de dépassement sensiblement égales le long des bordures verticales et des bordures horizontales dans l'exemple représenté.The outer glass sheet 6 is larger than the inner glass sheet 5 and protrudes therefrom all around, with substantially equal excess widths along the vertical borders and horizontal borders in the example shown.

L'épaisseur de chacune des feuilles intérieure et extérieure 5, 6 est par exemple de 4 mm, les deux feuilles 5 et 6 emprisonnant une lame de gaz 8 de 13 mm d'épaisseur.The thickness of each of the inner and outer sheets 5, 6 is for example 4 mm, the two sheets 5 and 6 trapping a gas strip 8 13 mm thick.

L'espaceur 7 est constitué par quatre profilés 9 de section rectangulaire ou carrée en aluminium, deux disposés horizontalement et deux, verticalement si l'on considère la position de fermeture du guichet ouvrant 4.The spacer 7 consists of four profiles 9 of rectangular or square aluminum section, two horizontally and two vertically, if we consider the closed position of the opening opening 4.

A la place de profilés en aluminium, on peut avantageusement prévoir des profilés en matière plastique ou en matière plastique renforcée par des fibres, comme décrit par exemple dans les brevets européens 875 654 et 852 280 , de telles matières permettant de limiter davantage les pertes thermiques en réduisant le pont thermique.Instead of aluminum profiles, it is advantageous to provide profiles made of plastics material or fiber-reinforced plastic, as described, for example, in European patents. 875,654 and 852,280 such materials to further limit thermal losses by reducing the thermal bridge.

Les quatre profilés 9, ainsi disposés selon un rectangle, sont à chacun de leurs quatre angles, complétés par une pièce d'angle coudée 10 en matière plastique, dont les bouts, disposés à 90° l'un de l'autre, pénètrent à force dans les ouvertures correspondantes à 90° de deux profilés adjacents.The four sections 9, thus arranged in a rectangle, are at each of their four corners, supplemented by a bent angle piece 10 made of plastics material, the ends of which, arranged at 90 ° from each other, penetrate to force in the openings corresponding to 90 ° of two adjacent sections.

Les feuilles 5 et 6 sont collées à deux côtés en regard des profilés 9 par des couches de joint -colle d'étanchéité 11, notamment en caoutchouc butyle noir. La feuille 5 est appliquée contre les côtés intérieurs des quatre profilés 9 formant le cadre en débordant légèrement à l'extérieur des côtés externes des profilés 9 qui sont perpendiculaires à ceux coopérant avec les feuilles 5 et 6 par l'interposition des couches de joint-colle 11.The sheets 5 and 6 are glued to two sides facing the profiles 9 by seal-seal layers 11, in particular black butyl rubber. The sheet 5 is applied against the inner sides of the four profiles 9 forming the frame projecting slightly outside the outer sides of the profiles 9 which are perpendicular to those cooperating with the sheets 5 and 6 by the interposition of the layers of joint. glue 11.

Le cadre 7 porte sur tout son pourtour, en application sur lesdits côtés externes, une couche 12 de polysulfure ou de silicone qui vient au droit de la bordure libre légèrement dépassante de la feuille 5.The frame 7 carries all around its periphery, in application on said outer sides, a layer 12 of polysulfide or silicone which comes to the right of the slightly protruding free edge of the sheet 5.

La feuille 6 porte, le long de sa bordure inférieure, des lames rectangulaires 13a de charnières 13 dont les autres lames rectangulaires 13b sont portées par la structure du réfrigérateur 1. Ces lames 13a sont avantageusement collées sur le verre. Les axes d'articulation 13c des charnières 13 sont également vus sur la Figure 1.The sheet 6 carries, along its lower edge, rectangular blades 13a of hinges 13 the other rectangular blades 13b are carried by the structure of the refrigerator 1. These blades 13a are advantageously bonded to the glass. The hinge pins 13c of the hinges 13 are also seen on the Figure 1 .

Une poignée 14 est rapportée par exemple par collage au voisinage de la bordure supérieure de la feuille 6 et au centre de celle-ci.A handle 14 is attached for example by gluing in the vicinity of the upper edge of the sheet 6 and in the center thereof.

Dans ce mode de réalisation, le guichet ouvrant 3 est, en position fermée, encastré (encastrement dit « flush ») au sein de la porte 2 du réfrigérateur 1. Les déperditions calorifiques lors de l'ouverture du guichet sont minimales, le double vitrage reste toujours transparent, sans embuage, l'isolation étant excel lente et le verre utilisé pour le double vitrage n'étant ni fragile, ni susceptible d'être rayé.In this embodiment, the opening opening 3 is, in the closed position, recessed (so-called "flush" installation) within the door 2 of the refrigerator 1. The heat loss during the opening of the window is minimal, the double glazing always remains transparent, without fogging, the insulation being excel slow and the glass used for the double glazing being neither fragile nor likely to be scratched.

Le guichet 3 du mode de réalisation représenté sur les Figures 4 et 5 diffère de celui des Figures 1 à 3 par le fait que la feuille 6 la plus large est tournée vers l'intérieur du réfrigérateur 1 en position d'utilisation. Les mêmes chiffres de référence que pour le premier mode de réalisation ont donc été utilisés pour simplifier. Egalement, les lames 13a des charnières 13 sont collées contre la face inférieure externe de la feuille 6.The window 3 of the embodiment shown on the Figures 4 and 5 differs from that of Figures 1 to 3 in that the widest sheet 6 is turned towards the inside of the refrigerator 1 in the position of use. The same reference numbers as for the first embodiment have therefore been used to simplify. Also, the blades 13a of the hinges 13 are glued against the outer lower face of the sheet 6.

Dans ce mode de réalisation, un cadre 15, en matière plastique, vient s'appuyer contre la feuille externe 5 pour la protéger ainsi que l'espaceur 9. Le cadre 15, qui contribue également à l'aspect esthétique du guichet ouvrant, comporte un entourage 15a qui enserre le chant du double vitrage et qui présente un retour 15b vers l'intérieur qui vient se placer contre la paroi externe 5. L'entourage 15a comporte intérieurement de façon classique des alvéoles 15c séparées par des nervures 15d, ce qui permet d'économiser de la matière dans ces régions tout en maintenant une rigidité suffisante pour le cadre 15. La bordure intérieure de l'entourage 15a peut par ailleurs avantageusement comporter, de place en place, des nervures de positionnement du cadre 15, venant en appui contre le chant du double vitrage afin d'assurer un meilleur maintien.In this embodiment, a frame 15, made of plastic, bears against the outer sheet 5 to protect it and the spacer 9. The frame 15, which also contributes to the aesthetic appearance of the opening window, comprises an entourage 15a which encloses the edge of the double glazing and which has a return 15b to the interior which is placed against the outer wall 5. The surrounding 15a conventionally comprises 15c internally cavities separated by ribs 15d, which saves material in these regions while maintaining sufficient rigidity to the frame 15. The inner edge of the surround 15a may also advantageously comprise, from place to place, positioning ribs of the frame 15, bearing against the edge of the double glazing to ensure better support.

Dans ce mode de réalisation la poignée 14 est vissée sur la bordure supérieure horizontale du retour 15b du cadre 15.In this embodiment, the handle 14 is screwed onto the horizontal upper edge of the return 15b of the frame 15.

On pourra par ailleurs prévoir que le guichet ouvrant 4 puisse être maintenu horizontal dans sa position ouverte, à la manière d'un bar. A cet effet, il est prévu un dispositif classique de type compas quart -de-cercle, comprenant des coulisseaux latéraux 16 fixés aux bordures latérales du cadre 15 par exemple à peu près au 1/3 de leur hauteur à partir de la bordure horizontale inférieure. Ces coulisseaux 16 sont en forme d'arcs de cercle et comportent chacun une ouverture centrale 16a oblonge de même forme. Une broche (non représentée), fixée à la structure du réfrigérateur 1, traverse chacune de ces ouvertures 16a et permet de retenir le guichet ouvrant lorsqu'il est en position horizontale, venant en butée à l'extrémité interne de l'ouverture 16a.We can also provide that the opening window 4 can be kept horizontal in its open position, in the manner of a bar. For this purpose, a conventional quarter-circle compass device is provided, comprising lateral slides 16 fixed to the lateral edges of the frame 15, for example approximately 1/3 of their height from the lower horizontal edge. . These slides 16 are in the form of circular arcs and each comprise a central opening 16a oblong of the same shape. A pin (not shown), attached to the structure of the refrigerator 1, passes through each of these openings 16a and allows to retain the opening window when in a horizontal position, abutting the inner end of the opening 16a.

Des joints assurant l'étanchéité de la fermeture des guichets (non représentés) sont prévus de façon classique, portés par la structure du réfrigérateur par exemple. On pourra également prévoir des moyens magnétiques ou mécaniques pour consolider cette fermeture.Seals sealing the closure of the wickets (not shown) are provided in a conventional manner, carried by the structure of the refrigerator by example. Magnetic or mechanical means may also be provided to consolidate this closure.

Sur la Figure 6, on a représenté un bandeau en verre 17 portant par exemple l'électronique de commande et les afficheurs de cet électronique. Sur la Figure 6, le bandeau 17 est représenté de face avec différents symboles 17a à 17e qui sont vus par transparence. A l'arrière du bandeau 17 , et en correspondance avec les symboles 17a, seront disposées des diodes associées à des détecteurs de chaleur, de telle sorte que le symbole puisse s'allumer ou s'éteindre selon la commande par appui du doigt sur celui ci (fonctions binaires). Les cinq symboles 17b sont des touches de réglage destinées à régler des valeurs qui s'affichent dans les fenêtres 17c, à l'arrière desquelles se trouvent par exemple des afficheurs à cristaux liquides. L'éclairage des symboles 17d est commandé par les touches 17b. L'éclairage du symbole 17e est commandé par exemple par les trois touches 17a voisines de celui-ci.On the Figure 6 , there is shown a glass strip 17 carrying for example the control electronics and displays of this electronics. On the Figure 6 , the strip 17 is shown from the front with different symbols 17a to 17e which are seen by transparency. At the rear of the strip 17, and in correspondence with the symbols 17a, will be arranged diodes associated with heat detectors, so that the symbol can turn on or off according to the command by pressing the finger on the ci (binary functions). The five symbols 17b are adjustment keys for setting values which are displayed in the windows 17c, behind which are, for example, liquid crystal displays. The lighting of the symbols 17d is controlled by the keys 17b. The illumination of the symbol 17e is controlled for example by the three keys 17a adjacent thereto.

Les commandes peuvent aussi être réalisées par des boutons classiques disposés sur le bandeau.The controls can also be realized by conventional buttons arranged on the headband.

La face arrière du bandeau 17 peut par exemple comporter avantageusement une première couche d'émail esthétique sauf à l'emplacement des symboles qui doivent être vus par transparence, puis des zones correspondant aux boutons de commande et aux capteurs de chaleur qui sont formées par exemple par dépôt d'argent, les zones précitées étant protégées extérieurement par un émail protecteur.The rear face of the strip 17 may for example advantageously comprise a first layer of enamel aesthetic except at the location of the symbols to be seen by transparency, then areas corresponding to the control buttons and the heat sensors which are formed for example by depositing silver, the aforementioned zones being protected externally by a protective enamel.

Il est bien entendu que les mode de réalisation de la présente invention qui viennent d'être décrits ont été donnés à titre indicatif et non limitatif et que des modifications peuvent être apportées sans que l'on s'écarte pour autant du cadre de la présente invention.It is understood that the embodiments of the present invention which have just been described have been given for information and not limitation and that modifications can be made without departing from the scope of the present invention.

En particulier le vitrage peut être non pas double mais triple ; l'un des verres peut être chauffé pour éviter la buée, le givre ou la condensation ; l'un des verres ou plusieurs peuvent porter différentes fonctions : anti - salissure par une couche photocatalytique à base de TiO2, une couche anti-givre comme dit dans le document de brevet EP 1 198 432 ; ce guichet peut être ouvrant en pivotant autour d'un axe vertical; etc..In particular the glazing can be not double but triple; one of the glasses may be heated to prevent fogging, frost or condensation; one or more glasses may carry different functions: antifouling by a photocatalytic layer based on TiO 2 , an anti-icing layer as described in the patent document EP 1 198 432 ; this window can be opening by pivoting about a vertical axis; etc ..

Egalement, et de façon générale selon l'invention, le guichet peut être en plusieurs éléments à la manière d'une fenêtre à deux vantaux.Also, and generally according to the invention, the window can be in several elements in the manner of a window with two leaves.
