Definitions
- the invention relates to a glazed opening for a climatic chamber, in particular refrigerated, comprising an insulating glazing unit comprising at least two glass substrates spaced by at least one gas strip using at least one spacer arranged at the periphery of the glass substrates, and means of articulation of the opening.
- the enclosure is more particularly intended to constitute a positive cold cabinet or a negative cold cabinet in which are exposed refrigerated or respectively frozen products, such as food products or beverages, or any other products requiring conservation in the cold, for example pharmaceuticals or flowers.
- a double or triple glazing is framed on its entire periphery by means of a frame made of profiles, usually anodized aluminum for reasons of aesthetics, resistance to aging and ease of manufacture.
- the frame is usually stuck directly on the periphery and on the outer faces of the glazing; it participates in the rigidity of the structure and makes it possible to hide in view the intermediate means disposed at the periphery of the glazing and separating the glass substrates.
- This frame also provides a means of support and attachment pivots, from which the opening is articulated with respect to the frame of the furniture.
- the object of the invention is therefore to provide an opening for a climatic chamber which obviates the various disadvantages mentioned above, by optimizing the compromise between, a field of vision that is as airy as possible through the glazing, and a maximized energy saving, all by not increasing or even decreasing the manufacturing costs of this opening.
- the glazing opening for a climatic chamber comprises a glazing unit comprising at least two glass substrates spaced apart by at least one spacer frame or spacer arranged at the periphery of the substrates to provide at least one gas strip between the substrates, and at least one less an oblong profile forming a support for hinge means of the opening, the opening being characterized in that the support profile is inserted between the two glass substrates, near the edge of the glazing and opposite the gas blade relative to the spacer.
- the hinge means are no longer dependent on a frame external to the glazing as known in the prior art, but are transferred to a support profile arranged between the glass substrates.
- This attachment of the hinge means of the integrated opening to the interior of the glazing thus eliminates the structural frame external to the glazing, making an opening more uncluttered and ensuring better clarity through the opening.
- the opening comprises a single support profile arranged along one side of the glazing, in particular vertically in the mounted position of the opening.
- the opening comprises two support profiles respectively arranged along two opposite sides of the glazing, in particular horizontally in the mounted position of the opening.
- This second embodiment is preferable because it makes it possible to limit the loss of vision between two adjacent openings, and ensures that the support profiles thus arranged do not obstruct the consumer's view of the products on display.
- the one or more sections are secured to the glass substrates by gluing means, of the type glue or double-sided adhesive.
- the hinge means are integrated, at the two ends of the section when it is alone in the opening, or at a single end of each section when two sections are provided in the opening, the articulation means being placed opposite in this last configuration.
- the hinge means cooperate with the profile or profiles so as to pivot the sash.
- the glazing comprises a sealing barrier, of the butyl bead type, over its entire periphery, this barrier being disposed between the glass substrates and the lateral faces of the intermediate frame or frames.
- another sealing barrier of the sealing mastic type, is added and placed between the glass substrates, against the profile or profiles and facing the outside of the glazing, the articulation means sealingly passing through this barrier.
- the glazing is a double glazing or triple glazing.
- the glazing comprises dressing means, in particular peripheral, masking the view or the support profiles, the spacer and the sealing barrier; these dressing means are for example a screen printing enamel or lacquer deposited directly on the glass, or rather shaped profiles reported on the outside of the glazing.
- the opening comprises means for protecting the edge of the glazing, in particular on the side opposite to that carrying the hinge means.
- protection means consist for example of at least one profile which also provides the dressing means described above for the spacer, and possibly the one or more support profiles.
- This protection profile does not produce a structural frame as in the prior art; it does not necessarily form a frame on the entire periphery of the glazing, and has dimensions advantageously limited to cover the edge of the glazing and advantageously to make more aesthetic opening by masking the spacer and possibly the profile or profiles, while optimizing the clear view.
- the opening of the opening comprises a handle attached to the glass of the glazing intended to be turned towards the external environment, by gluing or through fastening means, or by being combined or reported to the support profiles , or a protection profile arranged on the edge of the glazing opposite the side of the glazing carrying the hinge means.
- a first possibility is to fix this handle directly on the face of the outer glass of the glazing.
- a second possibility is to use a handle height equivalent to that of the opening and fix it by means of brackets on the support profiles.
- a third possibility is still to resort to a profile fixed on the vertical edge of the glazing opposite to that on which are arranged the hinge means, this profile combining the protection and dressing functions and integrating the handle by a protruding portion .
- the glazing is advantageously provided with one or more low-emissive coating (s) and / or an anti-fog or anti-frost layer, thus avoiding means heating, which contributes to energy savings.
- the opening is integrated in a door or wall comprising a frame with which the opening cooperates.
- the invention proposes to postpone this door closure return system to the frame of the door.
- the closure return system may further include the function of closing delay and / or end-of-closure damping.
- a delay in closing is therefore useful and acts as a delay of the opening before triggering the closing movement; the customer can freely take the products inside the furniture, while the door remains open.
- the time delay is limited in time to prevent opening times negatively affect the maintenance of the cold chain.
- the system can therefore also integrate the end-of-closure damping function, for example with a hydraulic or gas device.
- a system incorporating a damping function makes it possible to use at the door a peripheral gasket or bellows seal, or a single or multiple lip, which is not magnetic, preferably disposed on the frame, rather than a magnetic seal as in the prior art between the opening and the frame, the additional closing torque provided by the system with damping function to ensure sufficient pressure of the seal in the closed position of the opening to ensure the necessary seal between the frame and the opening.
- the peripheral seal installed between the opening and the frame is provided with an internal magnetic strip to ensure the seal its plating on the magnetic surface frame to ensure proper sealing.
- a magnetic seal is disadvantageous in terms of thermal insulation, because the magnetic strip and the magnetic surface against which the seal is applied are excellent thermal conductors which convey cold towards the periphery of the opening. This phenomenon of thermal bridge towards the aluminum used for the structural frame of the current doors generally results in the formation of condensation on said frame, making it necessary the use of heating cords (peripheral electrical resistance) which increase by the same amount the energy consumption of these furniture.
- the invention by no longer requiring a magnetic seal has the following advantages: a limitation of the thermal bridge, a manufacturing cost reduced by the absence of magnetic tape, a possible fixing of the seal either on the opening but on the frame, which simplifies and purify the opening and to prevent the seal is damaged during openings, to use translucent joints lighter aesthetically.
- the invention relates to a climatic chamber, refrigerated cabinet type, comprising at least one door or a door as described above.
- the climatic chamber 1 illustrated on the figure 1 comprises a frame 10 and a glazed opening 2 according to the invention as a whole a door.
- the enclosure could equally well comprise several butted openings 2A, 2B, 2C, etc., as visible on the figure 2 .
- the enclosure is for example a cold refrigerated unit positive to be installed along a store aisle. It is thus possible, according to the invention, to constitute a piece of furniture with a whole row of doors that are laterally abutted in a leaktight manner by means of joints arranged on their edges.
- the opening 2 of the invention comprises an insulating glazing unit 20, a handle 8, hinge means 3 and at least one support section 4 for the articulation means, this section being visible on the Figures 3 to 5 .
- the handle 8 is on this figure 1 glued to the glazing or fixed by means passing through.
- it can constitute a bar extending over the height of the glazing unit and fixed at its two ends to the support profiles 4 by fixing lugs.
- Insulating glazing 20 according to a first variant illustrated on the figures 3 and 4 , is a triple glazing. It can in another variant ( figure 5 ) consist only of double glazing. The triple glazing nevertheless ensures better thermal insulation.
- the triple glazing comprises a first glass substrate or inner substrate 21 whose outer face 21b is intended to be in contact with the interior of the enclosure in the closed position of the opening, a second glass substrate or intermediate substrate 22, and a third glass substrate or outer substrate 23 whose outer face 23a is intended to be in contact with the external environment to the enclosure.
- the faces of the substrates are noted in the usual manner, from (1) to (6), and correspond, respectively, to the outer face 23a intended to be in contact with the environment outside the enclosure, to the face 21b intended to be in contact with the interior of the enclosure in the closed position of the opening.
- the inner 21 and outer 23 substrates are preferably tempered glass.
- the thickness of each of the three substrates is between 2 and 5 mm, and is preferably 3 or 4 mm in order to minimize the overall weight of the glazing and to optimize the light transmission.
- the substrates are separated from each other by an intermediate element or spacer 24 to form between them a volume forming a gas blade 25.
- the spacer 24 is bonded by its side walls against the inner faces of the glass substrates, for example by means of butyl . As illustrated, two separate spacers 24a and 24b are provided but it is possible to envisage a single spacer which would be arranged astride the intermediate substrate 22.
- the spacer 24 is preferably of low thermal conductivity, having a coefficient of thermal conductivity of at most 1 W / m.K, preferably less than 0.7 W / m.K, and even less than 0.4 W / m.K.
- An example of a spacer has a base body made of a thermoplastic material, of the styrene acrylonitrile (SAN) or polypropylene type, and reinforcing fibers, of glass type, which are mixed with the thermoplastic material, as well as a metal foil sealing the gases and water vapor adhered to a portion of the base body, part intended to be disposed opposite the gas blade.
- the base body also houses a desiccant.
- Such a spacer based on SAN and glass fibers, is known for example under the trade name SWISSPACER ® from the company SAINT-GOBAIN GLASS when the metal sheet of the basic body is aluminum, and under the name SWISSPACER V ® when the metal sheet of the base body is made of stainless steel.
- the gas strip 25 has a thickness of at least 4 mm and is adapted according to the desired performance of the heat transfer coefficient U, without however being greater than 16 mm.
- the gas strip is made of air or preferably, to reinforce the insulation level of the glazing, a rare gas, chosen from argon, krypton, xenon, or a mixture of these different gases. , according to a filling rate of at least 85%. For a still improved U coefficient, it will be preferred a filling with at least 92% krypton or xenon.
- an additional sealing barrier 26 against liquids and steam is provided.
- This barrier is constituted for example by polysulfide, polyurethane, or silicone, and is disposed at the edge of the glazing, flush with the edge of the glass substrates.
- each face of the glazing of the opening has a temperature which is always greater than the temperature of the dew point of the environment with which the face is in contact. It is recalled that the temperature of the dew point is the temperature at which the vapor water present in the air begins to condense, and therefore the temperature at which the fog begins to form.
- the outer substrate 23 has on its face internal 23b (face (2)) facing the gas strip, a low-emissive transparent coating, based on layers of metal and / or metal oxides.
- the coating has the function of reflecting towards the outside of the enclosure, the infrared radiation arriving from the outside to the inner face, leading to a warming of the glass as a whole and therefore of the outer face, store side.
- An identical coating could also be deposited face (3), face (5) or preferably face (4).
- the glazing includes a layer or transparent film anti-fog or anti-icing. This layer is associated with the outer face 21b of the inner substrate 21 (face (6)).

- the insulating glazing of the opening is according to the invention provided with at least one profile 4 which provides the support of the hinge means 3 of the opening.
- the profile 4 is housed between the two inner and outer substrates of the glazing, against the spacer 24 and opposite to the gas strip 25 with respect to said spacer, the additional sealing barrier 26 being arranged above the profile and flush with the slices of glass substrates.
- the intermediate substrate is of smaller size than the inner and outer substrates so that this intermediate substrate bears on the profile 4, along a first side and is flush with the other three sides with the external substrate and the substrate. inside, by adding sealant.
- the glazing comprises two support profiles 4A and 4B, which are respectively disposed respectively on one side of the glazing and in opposite manner, in particular on the low and high horizontal sides in the mounted position of the opening in the furniture, these areas of the glazing being minor areas in terms of clear view.
- the support profile 4 is unique and arranged along one side of the glazing, vertically in the mounted position of the opening in the cabinet.
- the support profiles are preferably made of a material that is weakly thermally conductive, such as a plastic material of the PVC (polyvinyl chloride) or polyamide or polyacetate type, and which also has mechanical properties to withstand the stresses exerted on the articulation means. 3.

Abstract
Description
L'invention concerne un ouvrant vitré destiné à une enceinte climatique, en particulier réfrigérée, comportant un vitrage isolant comprenant au moins deux substrats verriers espacés par au moins une lame de gaz à l'aide d'au moins un espaceur agencé à la périphérie des substrats verriers, et des moyens d'articulation de l'ouvrant.The invention relates to a glazed opening for a climatic chamber, in particular refrigerated, comprising an insulating glazing unit comprising at least two glass substrates spaced by at least one gas strip using at least one spacer arranged at the periphery of the glass substrates, and means of articulation of the opening.
L'enceinte est plus particulièrement destinée à constituer un meuble à froid positif ou un meuble à froid négatif dans lequel sont exposés des produits réfrigérés ou respectivement surgelés, tels que des produits alimentaires ou boissons, ou tous autres produits nécessitant une conservation dans le froid, par exemple des produits pharmaceutiques ou des fleurs.The enclosure is more particularly intended to constitute a positive cold cabinet or a negative cold cabinet in which are exposed refrigerated or respectively frozen products, such as food products or beverages, or any other products requiring conservation in the cold, for example pharmaceuticals or flowers.
Si la commercialisation des produits congelés se fait de plus à plus à l'aide de meubles pourvus de portes, dites « froides », à vitrages isolants transparents, la commercialisation des produits alimentaires frais et ultrafrais en libre service se fait aujourd'hui essentiellement au moyen de meubles verticaux ouverts dans les magasins. Dotés d'un rideau d'air réfrigéré en face avant pour isoler les denrées alimentaires de l'ambiance chaude du magasin et les maintenir à la température de conservation optimale, ces meubles sont plutôt performants de ce point de vue et offrent un accès direct aux produits en l'absence de barrière physique, facilitant l'acte d'achat.If the marketing of frozen products is more and more using furniture equipped with doors, called "cold", with transparent insulating glass, the marketing of fresh and ultra-fresh food products in self-service is today mainly medium of vertical furniture open in the shops. Equipped with a refrigerated air curtain on the front to isolate the foodstuffs from the warm atmosphere of the store and keep them at the optimum storage temperature, these furniture are rather efficient from this point of view and offer direct access to produced in the absence of a physical barrier, facilitating the act of purchase.
Cependant l'absence de barrière physique sur ces meubles verticaux à froid positif entraîne un échange thermique important entre l'ambiance du magasin et l'ambiance beaucoup plus froide générée à l'intérieur de ces meubles, ce qui engendre les conséquences suivantes:
- cet échange thermique doit être compensé par une production de froid plus importante afin de garantir les températures optimales pour la conservation des aliments dans le meuble, ce qui accroît de manière néfaste la consommation énergétique de ces meubles;
- l'ambiance du magasin est considérablement refroidie localement (phénomène d'allée froide), ce qui conduit les consommateurs à limiter leur passage dans ces rayons pour les achats essentiels en délaissant les achats d'impulsion. Ce refroidissement local des allées concernées est d'autant plus accentué depuis ces dernières années que le renforcement des règles sanitaires a conduit à baisser encore la température de conservation des aliments;
- l'air humide de l'ambiance du magasin est drainé par le rideau d'air froid en face avant du meuble, ce qui conduit à une saturation rapide de l'échangeur de froid du meuble (appelé aussi évaporateur) qui se retrouve pris en glace, diminuant alors significativement l'efficacité de l'échange thermique. Il est donc nécessaire de procéder à des séquences de dégivrages fréquentes de l'évaporateur, typiquement deux fois par jour, ce qui entraîne une consommation énergétique accrue.
- this heat exchange must be compensated by a higher cold production in order to guarantee the optimal temperatures for the food preservation in the furniture, which adversely increases the energy consumption of this furniture;
- the atmosphere of the store is considerably cooled locally (cold aisle phenomenon), which leads consumers to limit their passage in these departments for essential purchases while neglecting impulse purchases. This local cooling of the alleys concerned is all the more accentuated in recent years as the reinforcement of the sanitary rules has led to further lowering the temperature of food preservation;
- the humid air of the store's atmosphere is drained by the cold air curtain in the front of the cabinet, which leads to a rapid saturation of the furniture's cold exchanger (also called evaporator) which is found in ice, thus significantly decreasing the efficiency of the heat exchange. It is therefore necessary to carry out frequent defrosting sequences of the evaporator, typically twice a day, resulting in increased energy consumption.
Face à ces inconvénients, les constructeurs de meubles ont tenté d'apporter des réponses, en optimisant notamment les rideaux d'air et en réchauffant les allées par des cassettes rayonnantes ou soufflantes à air chaud. Ce progrès reste néanmoins limité quant au confort des clients, et cela au détriment de la consommation énergétique. En effet, l'énergie calorifique produite par ces systèmes de chauffage qui sont gourmands en énergie se retrouve en partie dans les meubles, ce qui conduit au final à une consommation énergétique encore plus importante pour réfrigérer ces meubles.Faced with these disadvantages, furniture manufacturers have tried to provide answers, particularly by optimizing the air curtains and warming the aisles by radiating cassettes or blowers with hot air. However, this progress remains limited as regards the comfort of the customers, and this to the detriment of the energy consumption. Indeed, the heat energy produced by these energy-hungry heating systems is found partly in the furniture, which ultimately leads to an even greater energy consumption to refrigerate these pieces of furniture.
La mise en place de portes froides conventionnelles sur ces meubles ouverts permet de répondre efficacement à ces inconvénients. Ces solutions largement éprouvées en froid négatif pour des produits congelés, peinent cependant à se développer pour le froid positif. Il est reproché à ces portes de mettre une barrière physique entre le consommateur et le produit en libre service, pouvant générer des conséquences négatives potentielles sur les ventes.The implementation of conventional cold doors on these open furniture can effectively address these disadvantages. These solutions largely tested in negative cold for frozen products, however, struggle to develop for the positive cold. These doors are criticized for putting a physical barrier between the consumer and the self-service product, which can have potential negative consequences on sales.
En outre, ces ouvrants sont réalisés suivant une conception proche des fenêtres pour le bâtiment : un double ou triple vitrage est encadré sur l'ensemble de sa périphérie au moyen d'un cadre fait de profilés, généralement en aluminium anodisé pour des raisons d'esthétique, de résistance au vieillissement et de facilité de fabrication. Le cadre est généralement collé directement sur la périphérie et sur les faces externes du vitrage ; il participe à la rigidité de la structure et permet de masquer à la vue les moyens intercalaires disposés à la périphérie du vitrage et séparant les substrats verriers. Ce cadre assure également un moyen de support et de fixation des pivots, à partir desquels l'ouvrant s'articule par rapport au dormant du meuble.In addition, these openings are made in a design close to the windows for the building: a double or triple glazing is framed on its entire periphery by means of a frame made of profiles, usually anodized aluminum for reasons of aesthetics, resistance to aging and ease of manufacture. The frame is usually stuck directly on the periphery and on the outer faces of the glazing; it participates in the rigidity of the structure and makes it possible to hide in view the intermediate means disposed at the periphery of the glazing and separating the glass substrates. This frame also provides a means of support and attachment pivots, from which the opening is articulated with respect to the frame of the furniture.
Cependant un tel cadre structurel réduit de façon significative le clair de vue au travers du vitrage.However, such a structural frame significantly reduces the clarity of view through the glazing.
L'invention a donc pour but de réaliser un ouvrant pour enceinte climatique qui obvie aux différents inconvénients énoncés précédemment, en optimisant le compromis entre, un champ de vision le plus aéré possible au travers du vitrage, et une économie d'énergie maximisée, tout en n'augmentant pas, voire même en diminuant les coûts de fabrication de cet ouvrant.The object of the invention is therefore to provide an opening for a climatic chamber which obviates the various disadvantages mentioned above, by optimizing the compromise between, a field of vision that is as airy as possible through the glazing, and a maximized energy saving, all by not increasing or even decreasing the manufacturing costs of this opening.
Selon l'invention, l'ouvrant vitré pour enceinte climatique comporte un vitrage comprenant au moins deux substrats verriers espacés par au moins un cadre intercalaire ou espaceur agencé à la périphérie des substrats pour ménager au moins une lame de gaz entre les substrats, et au moins un profilé oblong formant un support pour des moyens d'articulation de l'ouvrant, l'ouvrant étant caractérisé en ce que le profilé support est inséré entre les deux substrats verriers, à proximité du bord du vitrage et à l'opposé de la lame de gaz par rapport à l'espaceur.According to the invention, the glazing opening for a climatic chamber comprises a glazing unit comprising at least two glass substrates spaced apart by at least one spacer frame or spacer arranged at the periphery of the substrates to provide at least one gas strip between the substrates, and at least one less an oblong profile forming a support for hinge means of the opening, the opening being characterized in that the support profile is inserted between the two glass substrates, near the edge of the glazing and opposite the gas blade relative to the spacer.
Par conséquent, les moyens d'articulation ne sont plus dépendants d'un cadre externe au vitrage tel que connu dans l'art antérieur, mais sont transférés sur un profilé support agencé entre les substrats verriers.Therefore, the hinge means are no longer dependent on a frame external to the glazing as known in the prior art, but are transferred to a support profile arranged between the glass substrates.
Cette fixation des moyens d'articulation de l'ouvrant intégrée à l'intérieur du vitrage supprime de ce fait le cadre structurel externe au vitrage, rendant un ouvrant davantage épuré et assurant un meilleur clair de vue au travers de l'ouvrant.This attachment of the hinge means of the integrated opening to the interior of the glazing thus eliminates the structural frame external to the glazing, making an opening more uncluttered and ensuring better clarity through the opening.
De plus, on diminue le nombre d'éléments constitutifs de l'ouvrant, conduisant à une réduction des coûts de fabrication.In addition, it reduces the number of components of the opening, leading to a reduction in manufacturing costs.
Selon un mode de réalisation, l'ouvrant comporte un unique profilé support agencé le long d'un côté du vitrage, en particulier de manière verticale en position montée de l'ouvrant.According to one embodiment, the opening comprises a single support profile arranged along one side of the glazing, in particular vertically in the mounted position of the opening.
Selon un autre mode de réalisation, l'ouvrant comporte deux profilés support agencés respectivement le long de deux côtés opposés du vitrage, en particulier de manière horizontale en position montée de l'ouvrant. Ce deuxième mode de réalisation est préférable car il permet de limiter la perte de clair de vue entre deux ouvrants adjacents, et assure que les profilés supports ainsi agencés ne viennent pas obstruer la vision du consommateur sur les produits exposés à la vente.According to another embodiment, the opening comprises two support profiles respectively arranged along two opposite sides of the glazing, in particular horizontally in the mounted position of the opening. This second embodiment is preferable because it makes it possible to limit the loss of vision between two adjacent openings, and ensures that the support profiles thus arranged do not obstruct the consumer's view of the products on display.
Selon une caractéristique, le ou les profilés sont solidarisés aux substrats verriers par des moyens de collage, du type colle ou adhésif double-face.According to one characteristic, the one or more sections are secured to the glass substrates by gluing means, of the type glue or double-sided adhesive.
Avantageusement, les moyens d'articulation sont intégrés, au niveau des deux extrémités du profilé lorsque celui-ci est seul dans l'ouvrant, ou au niveau d'une seule extrémité de chaque profilé lorsque deux profilés sont prévus dans l'ouvrant, les moyens d'articulation étant mis en regard dans cette dernière configuration.Advantageously, the hinge means are integrated, at the two ends of the section when it is alone in the opening, or at a single end of each section when two sections are provided in the opening, the articulation means being placed opposite in this last configuration.
Selon une autre caractéristique, les moyens d'articulation coopèrent avec le ou les profilés de façon à assurer un pivotement de l'ouvrant.According to another characteristic, the hinge means cooperate with the profile or profiles so as to pivot the sash.
Pour fournir à l'ouvrant les performances requises d'étanchéité à la vapeur d'eau et au gaz, le vitrage comporte une barrière d'étanchéité, du type cordon de butyle, sur l'ensemble de sa périphérie, cette barrière étant disposée entre les substrats verriers et les faces latérales du ou des cadres intercalaires. De plus, afin de compléter l'étanchéité à l'humidité, une autre barrière d'étanchéité, du type mastic d'étanchéité, est ajoutée et disposée entre les substrats verriers, contre le ou les profilés et en regard de l'extérieur du vitrage, les moyens d'articulation traversant de manière étanche cette barrière.To provide the opening the required performance of water vapor and gas tightness, the glazing comprises a sealing barrier, of the butyl bead type, over its entire periphery, this barrier being disposed between the glass substrates and the lateral faces of the intermediate frame or frames. In addition, in order to complete the moisture-tightness, another sealing barrier, of the sealing mastic type, is added and placed between the glass substrates, against the profile or profiles and facing the outside of the glazing, the articulation means sealingly passing through this barrier.
Selon une autre caractéristique, le vitrage est un double vitrage ou triple vitrage.According to another characteristic, the glazing is a double glazing or triple glazing.
De préférence, le vitrage comporte des moyens d'habillage, en particulier périphériques, masquant à la vue le ou les profilés support, l'espaceur et la barrière d'étanchéité ; ces moyens d'habillage sont par exemple une sérigraphie d'émail ou de laque déposée directement sur le verre, ou plutôt formés de profilés rapportés sur l'extérieur du vitrage.Preferably, the glazing comprises dressing means, in particular peripheral, masking the view or the support profiles, the spacer and the sealing barrier; these dressing means are for example a screen printing enamel or lacquer deposited directly on the glass, or rather shaped profiles reported on the outside of the glazing.
Avantageusement, l'ouvrant comporte des moyens de protection de la tranche du vitrage, en particulier du côté opposé à celui portant les moyens d'articulation. Ces moyens de protection consistent par exemple en au moins un profilé qui assure également les moyens d'habillage décrits ci-dessus pour l'espaceur, et éventuellement du ou des profilés support.Advantageously, the opening comprises means for protecting the edge of the glazing, in particular on the side opposite to that carrying the hinge means. These protection means consist for example of at least one profile which also provides the dressing means described above for the spacer, and possibly the one or more support profiles.
Ce profilé de protection ne réalise pas un cadre structurel comme dans l'art antérieur ; il ne forme pas forcément un cadre sur toute la périphérie du vitrage, et présente des dimensions avantageusement limitées à recouvrir la tranche du vitrage et avantageusement à rendre plus esthétique l'ouvrant en masquant l'espaceur et éventuellement le ou les profilés, tout en optimisant le clair de vue.This protection profile does not produce a structural frame as in the prior art; it does not necessarily form a frame on the entire periphery of the glazing, and has dimensions advantageously limited to cover the edge of the glazing and advantageously to make more aesthetic opening by masking the spacer and possibly the profile or profiles, while optimizing the clear view.
Pour l'ouverture de l'ouvrant, celui-ci comporte une poignée fixée au verre du vitrage destiné à être tourné vers l'environnement extérieur, par collage ou par des moyens de fixation traversants, ou encore en étant combinée ou rapportée aux profilés support, ou à un profilé de protection agencé sur la tranche du vitrage opposée au côté du vitrage portant les moyens d'articulation.For the opening of the opening, it comprises a handle attached to the glass of the glazing intended to be turned towards the external environment, by gluing or through fastening means, or by being combined or reported to the support profiles , or a protection profile arranged on the edge of the glazing opposite the side of the glazing carrying the hinge means.
Par exemple, une première possibilité est de fixer cette poignée directement sur la face du verre extérieur du vitrage.For example, a first possibility is to fix this handle directly on the face of the outer glass of the glazing.
Une seconde possibilité est d'utiliser une poignée de hauteur équivalente à celle de l'ouvrant et de la fixer au moyen de pattes de fixation sur les profilés supports.A second possibility is to use a handle height equivalent to that of the opening and fix it by means of brackets on the support profiles.
Une troisième possibilité est encore de recourir à un profilé fixé sur la tranche verticale du vitrage opposée à celle sur laquelle sont disposés les moyens d'articulation, ce profilé combinant les fonctions de protection et d'habillage et intégrant la poignée par une partie en saillie.A third possibility is still to resort to a profile fixed on the vertical edge of the glazing opposite to that on which are arranged the hinge means, this profile combining the protection and dressing functions and integrating the handle by a protruding portion .
L'ouvrant étant destiné à une enceinte climatique, le vitrage est avantageusement pourvu d'un ou de plusieurs revêtement(s) bas-émissif(s) et/ou d'une couche anti-buée ou anti-givre, évitant ainsi des moyens de chauffage usuels, ce qui participe à une économie d'énergie.The opening being intended for a climatic chamber, the glazing is advantageously provided with one or more low-emissive coating (s) and / or an anti-fog or anti-frost layer, thus avoiding means heating, which contributes to energy savings.
Selon l'invention, l'ouvrant est intégré à une porte ou paroi comportant un dormant avec lequel coopère l'ouvrant.According to the invention, the opening is integrated in a door or wall comprising a frame with which the opening cooperates.
Afin d'éviter que les portes froides ne restent malencontreusement ouvertes en magasin, elles sont systématiquement dotées d'un système de rappel afin de les refermer sans assistance dès qu'elles ne sont plus maintenues ouvertes par les clients. Ces systèmes font appel le plus souvent à une tige de torsion ou à un ressort à boudin.In order to prevent the cold doors from accidentally opening in the store, they are systematically equipped with a reminder system in order to close them without assistance as soon as they are no longer kept open by the customers. These systems most often use a torsion rod or a coil spring.
Dans l'art antérieur, un tel système de rappel de fermeture de porte est généralement intégré dans le montant vertical de l'encadrement de l'ouvrant, ce qui participe à la largeur du cadre structurel et à la perte de clair de vue qui s'en suit.In the prior art, such a door closure return system is generally integrated in the vertical amount of the frame of the opening, which contributes to the width of the structural frame and the loss of clarity that follows.
Afin de minimiser la perte de clair de vue porte à porte, c'est-à-dire selon une ligne verticale des ouvrants en position montée, et minimiser le poids et l'usage de matériaux fortement conducteurs d'un point de vue thermique dans les ouvrants, l'invention propose de reporter ce système de rappel de fermeture porte vers le dormant de la porte.To minimize the loss of clear door-to-door, that is to say along a vertical line of the opening in mounted position, and minimize the weight and the use of thermally conductive materials in a thermal point of view in the opening, the invention proposes to postpone this door closure return system to the frame of the door.
Le système de rappel de fermeture peut comporter en outre la fonction de retard à la fermeture et/ou d'amortissement de fin de fermeture.The closure return system may further include the function of closing delay and / or end-of-closure damping.
Sans possibilité de blocage temporaire en position ouverte de la porte, les clients des magasins doivent alors maintenir la porte ouverte, soit avec une main, soit avec une épaule, soit encore avec une jambe ce qui n'est effectivement pas confortable. Un retard à la fermeture est donc utile et agit comme une temporisation de l'ouverture avant déclenchement du mouvement de fermeture ; le client peut librement prendre les produits à l'intérieur du meuble, tandis que la porte reste maintenue ouverte.Without the possibility of temporary blockage in the open position of the door, shoppers must then keep the door open, either with a hand, with a shoulder, or with a leg which is actually not comfortable. A delay in closing is therefore useful and acts as a delay of the opening before triggering the closing movement; the customer can freely take the products inside the furniture, while the door remains open.
La temporisation est limitée dans le temps pour éviter que les temps d'ouverture n'influent négativement sur le maintien de la chaîne du froid. On choisira alors une temporisation unique non réglable en magasin (permettant de diminuer le coût de fabrication du système), avec un temps d'ouverture de 12 secondes conformément à la norme ISO 23953 correspondant aux meubles réfrigérés.The time delay is limited in time to prevent opening times negatively affect the maintenance of the cold chain. We will then choose a single non-adjustable timer in store (to reduce the cost of manufacturing the system), with an opening time of 12 seconds in accordance with ISO 23953 corresponding to refrigerated furniture.
Le système peut donc également intégrer la fonction d'amortissement de fin de fermeture, par exemple avec un dispositif hydraulique ou à gaz.The system can therefore also integrate the end-of-closure damping function, for example with a hydraulic or gas device.
Cette fonction supplémentaire permet d'éviter les contraintes mécaniques que pourraient subir le vitrage. En effet, aujourd'hui les portes n'intègrent pas de système d'amortissement à la fermeture. Lorsque la porte n'est plus maintenue ouverte par le client, le dispositif de fermeture à ressort rappelle la porte qui vient alors claquer contre le dormant. Bien que le joint d'étanchéité magnétique qui est à soufflet absorbe une partie de cette énergie de fermeture de la porte, la porte est néanmoins grandement sollicitée mécaniquement. Le système intégrant la fonction d'amortissement de fin de fermeture permet donc d'assurer avantageusement cet amortissement.This additional function makes it possible to avoid the mechanical stresses that the glazing could undergo. Indeed, today the doors do not incorporate a damping system at closing. When the door is no longer kept open by the customer, the spring closing device recalls the door which then snaps against the frame. Although the seal The bellows-type magnetic seal absorbs part of this closing energy of the door, but the door is nevertheless mechanically stressed. The system incorporating the end-of-closure damping function therefore makes it possible to advantageously ensure this damping.
Le recours à un système incorporant une fonction d'amortissement permet de plus d'utiliser au niveau de la porte un joint périphérique à boudin ou à soufflet, ou encore à lèvre simple ou multiple, qui n'est pas magnétique, de préférence disposé sur le dormant, plutôt qu'un joint magnétique comme dans l'art antérieur entre l'ouvrant et le dormant, le couple de fermeture supplémentaire fourni par le système à fonction d'amortissement permettant d'assurer une pression suffisante du joint en position fermée de l'ouvrant pour garantir l'étanchéité nécessaire entre le dormant et l'ouvrant.The use of a system incorporating a damping function makes it possible to use at the door a peripheral gasket or bellows seal, or a single or multiple lip, which is not magnetic, preferably disposed on the frame, rather than a magnetic seal as in the prior art between the opening and the frame, the additional closing torque provided by the system with damping function to ensure sufficient pressure of the seal in the closed position of the opening to ensure the necessary seal between the frame and the opening.
En effet, dans l'art antérieur, le joint périphérique installé entre l'ouvrant et le dormant est doté d'une bande interne magnétique pour garantir au joint son plaquage sur le dormant à surface magnétique afin d'assurer convenablement l'étanchéité. Cependant, un tel joint magnétique est désavantageux en terme d'isolation thermique, car la bande magnétique et la surface magnétique contre laquelle est appliquée le joint sont d'excellents conducteurs thermiques qui véhiculent le froid vers la périphérie de l'ouvrant. Ce phénomène de pont thermique vers l'aluminium utilisé pour le cadre structurel des portes actuelles se traduit généralement par la formation de condensation sur ledit cadre, rendant nécessaire le recours à des cordons chauffants (résistance électriques périphériques) qui augmentent d'autant la consommation énergétique de ces meubles.Indeed, in the prior art, the peripheral seal installed between the opening and the frame is provided with an internal magnetic strip to ensure the seal its plating on the magnetic surface frame to ensure proper sealing. However, such a magnetic seal is disadvantageous in terms of thermal insulation, because the magnetic strip and the magnetic surface against which the seal is applied are excellent thermal conductors which convey cold towards the periphery of the opening. This phenomenon of thermal bridge towards the aluminum used for the structural frame of the current doors generally results in the formation of condensation on said frame, making it necessary the use of heating cords (peripheral electrical resistance) which increase by the same amount the energy consumption of these furniture.
Par conséquent, l'invention en ne nécessitant plus de joint magnétique présente les avantages suivants : une limitation du pont thermique, un coût de fabrication réduit par l'absence de bande magnétique, une fixation possible du joint non plus sur l'ouvrant mais sur le dormant, ce qui permet de simplifier et d'épurer au maximum l'ouvrant et d'éviter que le joint ne soit abîmé lors des ouvertures, de recourir à des joints translucides plus légers esthétiquement.Therefore, the invention by no longer requiring a magnetic seal has the following advantages: a limitation of the thermal bridge, a manufacturing cost reduced by the absence of magnetic tape, a possible fixing of the seal either on the opening but on the frame, which simplifies and purify the opening and to prevent the seal is damaged during openings, to use translucent joints lighter aesthetically.
Enfin, l'invention est relative à une enceinte climatique, du type meuble réfrigéré, comportant au moins un ouvrant ou une porte tel que décrit ci-dessus.Finally, the invention relates to a climatic chamber, refrigerated cabinet type, comprising at least one door or a door as described above.

L'enceinte pourrait tout aussi bien comporter plusieurs ouvrants aboutés 2A, 2B, 2C, etc..., tels que visibles sur la
Dans le cas d'un meuble à froid négatif, pour garantir correctement l'étanchéité entre ouvrants et dormant, on préférera agencer des montants verticaux au niveau du dormant, à la fois au niveau de l'axe de pivotement et à l'opposé de l'axe de pivotement de l'ouvrant, de façon à avoir une surface continue d'appui pour le joint d'étanchéité sur toute la périphérie de la porte.In the case of a negative cold cabinet, to ensure proper sealing between openings and frame, it is preferred to arrange vertical amounts at the frame, both at the pivot axis and the opposite of the pivot axis of the opening, so as to have a continuous bearing surface for the seal over the entire periphery of the door.
Dans le cas d'un meuble à froid positif, l'étanchéité étant moins critique, il sera possible d'envisager de réduire, voire de supprimer les montants verticaux du dormant en réalisant l'étanchéité entre deux portes adjacentes au moyen de joints d'étanchéité disposés sur la tranche de l'ouvrant.In the case of a positive cold cabinet, the seal being less critical, it will be possible to consider reducing or even eliminate the vertical uprights of the frame by sealing between two adjacent doors by means of gaskets. sealing arranged on the edge of the opening.
La façade des ouvrants ainsi épurée de tout cadre structurel présente un aspect quasiment lisse de paroi de verre. On gagne de cette manière en espace de vision.The facade of the openings and refined any structural frame has a virtually smooth glass wall. We gain in this way in vision space.
L'ouvrant 2 de l'invention comporte un vitrage isolant 20, une poignée 8, des moyens d'articulation 3 et au moins un profilé 4 de support pour les moyens d'articulation, ce profilé étant visible sur les

Les faces des substrats sont notées de manière usuelle, de (1) à (6), et correspondent respectivement, à la face externe 23a destinée à être en contact avec l'ambiance extérieure à l'enceinte, jusqu'à la face 21 b destinée à être en contact avec l'intérieur de l'enceinte en position fermée de l'ouvrant.The faces of the substrates are noted in the usual manner, from (1) to (6), and correspond, respectively, to the
Les substrats intérieur 21 et extérieur 23 sont de préférence en verre trempé. L'épaisseur de chacun des trois substrats est comprise entre 2 et 5 mm, et est de préférence de 3 ou 4 mm afin de minimiser le poids global du vitrage et d'optimiser la transmission lumineuse.The inner 21 and outer 23 substrates are preferably tempered glass. The thickness of each of the three substrates is between 2 and 5 mm, and is preferably 3 or 4 mm in order to minimize the overall weight of the glazing and to optimize the light transmission.
Les substrats sont séparés entre eux par un élément intercalaire ou espaceur 24 pour ménager entre eux un volume formant une lame de gaz 25. L'espaceur 24 est collé par ses parois latérales contre les faces internes des substrats verriers, par exemple au moyen de butyle. Tel qu'illustré, deux espaceurs distincts 24a et 24b sont prévus mais il est possible d'envisager un espaceur unique qui serait agencé à cheval sur le substrat intermédiaire 22.The substrates are separated from each other by an intermediate element or
L'espaceur 24 est de préférence à basse conductivité thermique, en présentant un coefficient de conductivité thermique d'au plus 1 W/m.K, de préférence inférieur à 0,7 W/m.K, et même inférieur à 0,4 W/m.K.The
Un exemple d'espaceur présente un corps de base constitué d'une matière thermoplastique, du type styrène acrylonitrile (SAN) ou polypropylène, et de fibres de renforcement, de type en verre, qui sont mélangées à la matière thermoplastique, ainsi qu'une feuille métallique réalisant l'étanchéité aux gaz et à la vapeur d'eau collée sur une partie du corps de base, partie destinée à être disposée à l'opposé de la lame de gaz. Le corps de base loge par ailleurs un déshydratant.An example of a spacer has a base body made of a thermoplastic material, of the styrene acrylonitrile (SAN) or polypropylene type, and reinforcing fibers, of glass type, which are mixed with the thermoplastic material, as well as a metal foil sealing the gases and water vapor adhered to a portion of the base body, part intended to be disposed opposite the gas blade. The base body also houses a desiccant.
Un tel espaceur, à base de SAN et de fibres de verre, est connu par exemple sous la dénomination commerciale SWISSPACER® de la société SAINT-GOBAIN GLASS lorsque la feuille métallique du corps de base est en aluminium, et sous la dénomination SWISSPACER V® lorsque la feuille métallique du corps de base est en acier inoxydable.Such a spacer, based on SAN and glass fibers, is known for example under the trade name SWISSPACER ® from the company SAINT-GOBAIN GLASS when the metal sheet of the basic body is aluminum, and under the name SWISSPACER V ® when the metal sheet of the base body is made of stainless steel.
La lame de gaz 25 présente une épaisseur d'au moins 4 mm et est adaptée en fonction des performances souhaitées du coefficient de transfert thermique U, sans être toutefois supérieure à 16 mm.The
La lame de gaz est constituée d'air ou de préférence, pour renforcer le niveau d'isolation du vitrage, d'un gaz rare, choisi parmi l'argon, le krypton, le xénon, ou d'un mélange de ces différents gaz, selon un taux de remplissage d'au moins 85%. Pour un coefficient U encore amélioré, il sera préféré un remplissage avec au moins 92% de krypton ou de xénon.The gas strip is made of air or preferably, to reinforce the insulation level of the glazing, a rare gas, chosen from argon, krypton, xenon, or a mixture of these different gases. , according to a filling rate of at least 85%. For a still improved U coefficient, it will be preferred a filling with at least 92% krypton or xenon.
Si l'espaceur 24 assure par sa face métallique opposée à la lame de gaz une étanchéité aux gaz et à la vapeur d'eau, il est prévu une barrière d'étanchéité supplémentaire 26 contre les liquides et la vapeur. Cette barrière est constituée par exemple par du polysulfure, du polyuréthane, ou du silicone, et est disposée en bord du vitrage, affleurant la tranche des substrats verriers.If the
Il est impératif d'assurer en permanence la vision à l'intérieur du meuble quel que soit le nombre d'ouvertures répétées de l'ouvrant. Or l'ouverture de l'ouvrant soulève le problème de la buée ou du givre en raison de l'ambiance chaude du magasin opposée à l'ambiance froide à l'intérieur du meuble.It is imperative to permanently ensure the vision inside the furniture whatever the number of repeated openings of the opening. Or the opening of the opening raises the problem of steam or frost because of the warm atmosphere of the store opposite the cold atmosphere inside the furniture.
Selon l'invention, chaque face du vitrage de l'ouvrant présente une température qui est toujours supérieure à la température du point de rosée de l'ambiance avec laquelle la face est en contact. On rappelle que la température du point de rosée est la température à laquelle la vapeur d'eau présente dans l'air commence à se condenser, et donc la température à laquelle la buée commence à se former. Afin d'éviter la condensation sur la face extérieure 23a de l'ouvrant (face (1), côté magasin) sans avoir recours à une couche transparente chauffante pour des raisons d'économie d'énergie, le substrat extérieur 23 comporte sur sa face interne 23b (face (2)) en regard de la lame de gaz, un revêtement transparent bas-émissif, à base de couches de métal et/ou d'oxydes métalliques. Le revêtement a pour fonction de réfléchir vers l'extérieur de l'enceinte, le rayonnement infrarouge arrivant depuis l'extérieur jusqu'à la face intérieure, conduisant à un réchauffement du verre dans son ensemble et donc de la face extérieure, côté magasin. Un revêtement identique pourrait aussi être déposé en face (3), en face (5) ou de préférence en face (4).According to the invention, each face of the glazing of the opening has a temperature which is always greater than the temperature of the dew point of the environment with which the face is in contact. It is recalled that the temperature of the dew point is the temperature at which the vapor water present in the air begins to condense, and therefore the temperature at which the fog begins to form. In order to avoid condensation on the
L'utilisation d'un vitrage très isolant se traduit par des températures de surface interne très proches des températures internes du meuble, donc plutôt basses. De ce fait, il peut se former des phénomènes indésirables de buée ou de givre, lorsque ces surfaces internes sont exposées à l'ambiance du magasin lors des séquences d'ouverture de l'ouvrant.The use of a highly insulating glazing results in internal surface temperatures very close to the internal temperatures of the cabinet, so rather low. As a result, undesirable phenomena of misting or frost may be formed when these internal surfaces are exposed to the atmosphere of the store during opening sequences of the opening.
Pour éviter ces phénomènes et conserver la transparence, y compris lors des ouvertures de l'ouvrant, il est souhaitable que le vitrage intègre une couche ou film transparent anti-buée ou anti-givre. Cette couche est associée à la face externe 21 b du substrat intérieur 21 (face (6)).To avoid these phenomena and maintain transparency, including during opening of the opening, it is desirable that the glazing includes a layer or transparent film anti-fog or anti-icing. This layer is associated with the
Pour plus de détails sur l'optimisation de la structure du vitrage isolant en vue de son isolation thermique et sur l'intégration d'une couche anti-buée ou anti-givre, on peut se référer à la demande de brevet
En optimisant le niveau d'isolation du vitrage, on peut minimiser l'échange thermique entre le milieu extérieur (magasin) et le milieu intérieur (le meuble réfrigéré) et donc limiter la consommation énergétique du meuble.By optimizing the insulation level of the glazing, it is possible to minimize the heat exchange between the external environment (store) and the indoor environment (the refrigerated cabinet) and thus limit the energy consumption of the furniture.
Dans une variante de réalisation, le vitrage isolant peut être un double vitrage, tel qu'illustré sur la
Le vitrage isolant de l'ouvrant est selon l'invention doté d'au moins un profilé 4 qui fournit le support des moyens d'articulation 3 de l'ouvrant.The insulating glazing of the opening is according to the invention provided with at least one
Le profilé 4 est logé entre les deux substrats intérieur et extérieur du vitrage, contre l'espaceur 24 et opposé à la lame de gaz 25 par rapport audit espaceur, la barrière d'étanchéité supplémentaire 26 étant disposée au-dessus du profilé et affleurant les tranches des substrats verriers. Pour un triple vitrage, le substrat intermédiaire est de dimension inférieure aux substrats intérieur et extérieur de sorte que ce substrat intermédiaire vienne en appui sur le profilé 4, selon un premier côté et soit affleurant sur le trois autres côtés avec le substrat extérieur et le substrat intérieur, en y associant du mastic d'étanchéité.The

Dans un second mode de réalisation illustré à la
Les profilés support sont réalisés de préférence dans un matériau faiblement conducteur thermiquement, tel qu'en matière plastique du type PVC (polychlorure de vinyle) ou polyamide ou polyacétate, et offrant également des propriétés mécaniques pour résister aux sollicitations exercées sur les moyens d'articulation 3.The support profiles are preferably made of a material that is weakly thermally conductive, such as a plastic material of the PVC (polyvinyl chloride) or polyamide or polyacetate type, and which also has mechanical properties to withstand the stresses exerted on the articulation means. 3.
La solidarisation des profilés est faite contre les faces internes des substrats verriers.The joining of the profiles is made against the inner faces of the glass substrates.
La fixation est réalisée par des moyens de collage 41, tels que de la colle ou un adhésif double-face, de préférence à base d'acrylique. Afin de maximiser le collage, un primage des surfaces peut être réalisé au moyen d'un promoteur d'adhérence préalablement à la mise en place des moyens de collage.Fixing is performed by gluing
Les profilés support 4 sont en matériau plein dans la zone de support des moyens d'articulation 3, et de préférence creux pour le reste du corps afin de minimiser la conduction thermique d'une face à l'autre du vitrage. La section des profilés est plutôt rectangulaire, ou en U, ou en H.The support profiles 4 are made of solid material in the support zone of the articulation means 3, and preferably hollow for the rest of the body in order to minimize the heat conduction from one side to the other of the glazing. The section of the profiles is rather rectangular, or in U, or H.
Chaque profilé comporte un logement d'accueil 42 dont la forme et la structure sont adaptées pour accueillir en coopération mutuelle les moyens d'articulation 3. Ce logement est formé directement dans le corps du profilé ou peut constituer un insert qui est rapporté dans le corps du profilé par collage ou soudage ou par emmanchement à force au moyen d'une presse.Each section comprises a receiving
Les moyens d'articulation 3 consistent de préférence en un pivot monté libre en rotation dans le logement 42 du profilé support 4 et monté fixe sur le dormant 10, ou solidaire de ce logement 42 et monté libre en rotation sur le dormant 10 (pour l'entraînement du dispositif ferme porte).The articulation means 3 preferably consist of a pivot mounted free to rotate in the
Si le transfert des moyens d'articulation depuis le cadre structurel de l'art antérieur vers le vitrage permet selon l'invention d'éliminer ce dit cadre, il est néanmoins nécessaire de protéger la périphérie du vitrage des chocs éventuels (liés notamment aux chariots dans un magasin) afin de maintenir l'intégrité des substrats verriers dans le temps. En outre, il est souhaitable de masquer les profilés et divers matériaux d'assemblage du vitrage, visibles par transparence au travers du verre.If the transfer of the articulation means from the structural frame of the prior art to the glazing allows according to the invention to eliminate said frame, it is nevertheless necessary to protect the periphery of the glazing possible shocks (related in particular to the carts in a store) to maintain the integrity of the glass substrates over time. In addition, it is desirable to hide the profiles and various assembly materials of the glazing, visible through transparency through the glass.
A ces fins, on ajoute (
Les moyens de protection 5 sous forme de profilés peuvent être réalisés par extrusion, usinés pour une mise à longueur idoine, et pour la réalisation de dégagements nécessaires au passage des moyens d'articulation 3. Ils sont ensuite assemblés autour du vitrage. Une méthode alternative peut être d'injecter ou de surmouler un plastique sur la périphérie du vitrage.The protection means 5 in the form of profiles can be made by extrusion, machined for an appropriate length, and for making clearances necessary for the passage of the hinge means 3. They are then assembled around the glazing. An alternative method may be to inject or overmold a plastic on the periphery of the glazing.
Les moyens d'habillage 6 peuvent consister en une sérigraphie périphérique d'émail ou de laque (epoxy, PU,..) déposée sur le substrat verrier extérieur 23 de l'ouvrant. Il peut également s'agir de profilés d'habillage qui constituent en outre les moyens 5 de protection de la tranche du vitrage.The dressing means 6 may consist of a peripheral screen printing enamel or lacquer (epoxy, PU, ..) deposited on the
Les profilés de masquage et de protection 6 tels que visibles sur la
Si le cadre structurel d'un ouvrant actuel a une largeur de 35 à 40 mm sur l'ensemble de la périphérie de l'ouvrant, l'invention permet de minimiser la perte de clair de vue en ne disposant des moyens de masquage 6 qui n'excèdent pas 15 mm environ sur les côtés ne présentant pas de profilés support 4, cachant simplement l'espaceur et la barrière d'étanchéité du vitrage isolant.If the structural frame of a current opening has a width of 35 to 40 mm over the entire periphery of the opening, the invention makes it possible to minimize the loss of vision by not having masking means 6 which do not exceed about 15 mm on the sides not having

Avantageusement, le système de rappel de fermeture intègre une fonction de retard à la fermeture, ce qui assure de maintenir la porte ouverte pendant un temps préprogrammé afin que le consommateur prenne librement les produits dans le meuble réfrigéré.Advantageously, the closure return system incorporates a closing delay function, which ensures that the door is kept open for a preprogrammed time so that the consumer can freely take the products in the refrigerated cabinet.
En outre, le système peut intégrer une fonction d'amortissement de fin de fermeture, soit avec un dispositif hydraulique, soit avec un dispositif à gaz. Ce système assure une fermeture douce, et évite inutilement de solliciter mécaniquement la porte lors des fermetures, ce qui est d'autant plus opportun que le vitrage de l'invention ne comporte pas de cadre structurel comme dans l'art antérieur.In addition, the system can integrate a closure damping function, either with a hydraulic device or with a gas device. This system provides a soft closure, and avoids unnecessarily mechanically solicit the door during closures, which is all the more appropriate that the glazing of the invention does not include a structural frame as in the prior art.
L'utilisation d'un système intégrant une fonction d'amortissement permet de remplacer le joint magnétique usuel associé à tout ouvrant habituel de porte froide, par un simple joint à boudin, à lèvre(s) simples ou multiples ou à soufflet 9 qui n'est pas magnétique (
Enfin est décrit sommairement le procédé de fabrication d'un ouvrant selon l'invention. Ce procédé consiste à fabriquer un vitrage isolant incorporant les profilés 4 et à monter les moyens d'articulation 3 lors de la finition du vitrage, ou après la fabrication du vitrage.Finally is briefly described the method of manufacturing an opening according to the invention. This method consists in manufacturing an insulating glazing incorporating the
Les étapes de fabrication du vitrage isolant vont à présent être décrites. Les premières étapes sont illustrées sur la
- Etape (1): Lavage d'un premier substrat verrier 21 et mise en référence de deux côtés perpendiculaires du substrat contre des butées horizontales inférieures 100 et verticales 110;
- Etape (2) : Positionnement et collage d'un
premier profilé support 4A en référence contre un deuxième niveau de butées verticales 111, en décalage avec les bords du substrat afin de ménager la réserve nécessaire pour la mise en place future de la barrière d'étanchéité en mastic; - Etape (3) : Mise en place de l'espaceur 24 (
ou 24a pour un triple vitrage) par collage sur le substrat 21 à l'aide d'un cordon d'étanchéité en butyle. L'espaceur est accolé au profilésupport 4A et mis en référence contre un deuxième niveau de butées horizontales inférieures 101, toujours pour ménager la réserve nécessaire à la mise en place future de la barrière d'étanchéité en mastic. Ce sous-ensemble est ensuite mis de côté. - Etape (4) : Dans le cas d'un triple vitrage, lavage du substrat verrier intermédiaire 22, et mise en référence du substrat sur deux côtés perpendiculaires au moyen de butées horizontales inférieures 102 et verticales 112.
- Etape (5) : Toujours dans le cas d'un triple vitrage, mise en place sur
ce substrat intermédiaire 22, du deuxième espaceur 24b et collage par un cordon de butyle. Le substrat intermédiaire étant de dimensions plus courtes que lepremier substrat 21, l'espaceur est collé en bord à bord avec le verre au niveau des côtés verticaux, et mis en référence au niveau du côté horizontal inférieur avec un deuxième niveau de butées 103 qui permettent de ménager la réserve nécessaire à la mise en place future de la barrière d'étanchéité en mastic. - Etape (6) : Superposition de ce sous-ensemble formé du substrat intermédiaire 22 et de l'espaceur 24b, sur le premier sous-ensemble formé à partir du substrat 21 équipé du profilé
support 4A et de l'autre espaceur 24a. Le substrat intermédiaire 22 est correctement positionné au niveau du côté vertical en référence sur le profilésupport 4A et sur le premier niveau de butées horizontales inférieures 100, contre lesquels le substrat 22 vient en butée. - Etape (7) : Mise en place et collage sur le premier substrat 21de l'autre profilé 4B à l'extrémité opposée du profilé 4A.
Ce profilé 4B est positionné car il vient en appui contre le substrat intermédiaire 22 et/ou le(s) espaceur(s) 24 en référence contre une butée horizontale 104 pour ménager la réserve nécessaire à la mise en place de la future barrière d'étanchéité en mastic. - Puis de manière non illustrée : Pelage de la pellicule de protection de l'adhésif double-face des profilées 4A et 4B, ou mise en place du cordon de colle 41 sur ceux-ci ;
- Lavage et mise en place du dernier substrat verrier 23 en superposition bord à bord du
premier substrat 21; - Pressage de l'ensemble ;
- Si nécessaire, remplissage du gaz de manière connue (double perçage dans les espaceurs 24, un orifice servant au remplissage, tandis que l'autre permet à l'air de s'échapper);
- Eventuellement mise en place des moyens d'articulation 3 dans les profilés 4A et 4B;
- Mise en place du mastic d'étanchéité 26 à la périphérie du vitrage, en prenant le soin préalablement de protéger les moyens d'articulation, ou les logements 42 permettant de monter les moyens d'articulation ultérieurement, après finition du vitrage isolant.
- Step (1): Washing a
first glass substrate 21 and referencing two perpendicular sides of the substrate against lowerhorizontal stops 100 and vertical 110; - Step (2): Positioning and gluing of a
first support profile 4A in reference against a second level ofvertical stops 111, offset with the edges of the substrate in order to provide the necessary reserve for the future installation of the barrier. sealant sealant; - Step (3): Placement of spacer 24 (or 24a for triple glazing) by bonding to
substrate 21 using a butyl sealing bead. The spacer is attached to thesupport profile 4A and referenced against a second level of lowerhorizontal stops 101, again to provide the necessary reserve for the future installation of the sealing barrier sealant. This subset is then put aside. - Step (4): In the case of a triple glazing, washing the
intermediate glass substrate 22, and referencing the substrate on two perpendicular sides by means of 102 horizontal and vertical horizontal stops 112. - Step (5): Still in the case of triple glazing, placed on this
intermediate substrate 22, thesecond spacer 24b and bonded by a butyl bead. The intermediate substrate being of shorter dimensions than thefirst substrate 21, the spacer is glued edge-to-edge with the glass at the vertical sides, and referenced at the lower horizontal side with a second level ofstops 103 which allow to reserve the necessary reserve for the future installation of the sealant sealant barrier. - Step (6): Superposition of this sub-assembly formed of the
intermediate substrate 22 and thespacer 24b, on the first subassembly formed from thesubstrate 21 equipped with thesupport profile 4A and theother spacer 24a. Theintermediate substrate 22 is correctly positioned at the vertical side in reference to thesupport profile 4A and the first level of lowerhorizontal stops 100, against which thesubstrate 22 abuts. - Step (7): Placing and gluing on the
first substrate 21 of theother section 4B at the opposite end of thesection 4A. Thissection 4B is positioned because it abuts against theintermediate substrate 22 and / or the spacer (s) 24 in reference against ahorizontal abutment 104 to provide the reserve necessary for the installation of the future barrier. sealant sealant. - Then not shown: Peeling the protective film of the double-sided
4A and 4B, or placing theadhesive profiles adhesive bead 41 thereon; - Washing and placing the
last glass substrate 23 superimposed edge to edge of thefirst substrate 21; - Pressing of the whole;
- If necessary, filling the gas in known manner (double drilling in the
spacers 24, one opening for filling, while the other allows air to escape); - Optionally put in place the hinge means 3 in the
4A and 4B;profiles - Putting
sealant 26 on the periphery of the glazing, taking care beforehand to protect the hinge means, or thehousings 42 for mounting the hinge means later, after finishing the insulating glass.
