专利说明:

The invention relates to an insulating glazing unit for an opening of a chamber / climatic cabinet, in particular a refrigerated cabinet, comprising at least two sheets of glass spaced by at least one air gap or of gas using at least one spacer arranged at the periphery of the glass sheets, at least one transparent glass spacer being disposed on one side of the glazing. The invention also relates to the method of manufacturing such a glazing. The invention will be more particularly described with regard to a refrigerated furniture / showcase application, without being limited thereto. The glazing of the invention can be used in all building applications, exterior glazing, interior glazing, partition, etc.
Among the spacers, there are those made of synthetic material, organic material and glass.
The present invention relates exclusively to glass spacers.
A climatic chamber is more particularly intended to constitute a positive cold piece of furniture or a negative cold piece of furniture in which are exposed refrigerated or respectively frozen products, such as food products or beverages, or any other products requiring preservation in the cold, for example pharmaceuticals or flowers.
If the marketing of frozen products is made more and more using furniture with doors, called "cold", with transparent insulating glass, the marketing of fresh and ultra-fresh food products in self-service is today essentially by 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.
However, the absence of a physical barrier on these positive cold vertical furniture causes a significant heat exchange between the atmosphere of the store and the much colder atmosphere generated inside the furniture, which has the following consequences: - this heat exchange must be offset by increased cold production to ensure optimal temperatures for food storage 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 atmosphere of the store atmosphere is drained by the cold air curtain in the front of the cabinet, which leads to a rapid saturation of the furniture cold exchanger (also called evaporator) which is found caught in ice, thus significantly reducing the efficiency of the heat exchange. It is therefore necessary to carry out frequent defrosting sequences of the evaporator, typically twice a day, which leads to increased energy consumption and generates costs.
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.
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.
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 (spacers) arranged at the periphery of the glazing and separating the glass sheets.
However, such a structural frame significantly reduces the clarity of view through the glazing.
It was then proposed to improve the clarity of vision through glazing, to manufacture insulating glazing with transparent spacers at least at their vertical sides, generating further a visual perception of seamless surface continuity on all of them. refrigerated display cases joined to each other.
Today, the method of manufacturing a glazing unit with a glass spacer consists of cutting a glass rod of square or rectangular section and of a large thickness of the order of 15 mm (in particular 14.7 mm). The term "thickness" in the following description, the dimension extending in a plane parallel to the general surfaces of glass sheets in the mounted position of the spacer, that is to say the dimension extending from the singing of the glass sheets towards the inside of the glazing.
As for the "width" of the spacer, it corresponds to the size separating the two sheets of glass in the mounted position of the spacer.
It will be remembered that, in general, different glass cutting techniques exist: the most common technique is the combined technique of tracing, for example via a diamond wheel, and breaking; this technique is used for glasses with a thickness of 1 to 19 mm; - the technique of cutting by jet of water which makes it possible to cut glasses of bigger thicknesses; - The laser cutting technique that allows perfectly clean cuts but is very little industrialized and is not used in the manufacture of insulating glass because too expensive.
Cutting by tracing / breaking has the disadvantage of generating splines, not providing a clean and smooth surface condition of the cut edge.
However, to avoid any visual distortion in an insulating glass with glass spacer, at the interface between the spacer and the glass sheets, the faces of the spacer made integral with the glass sheets must have a state of perfectly smooth surface.
In addition, the break generates, especially at the beginning and end of the cutting line, a slight oblique edge of the cut glass; the edge is not perfectly orthogonal to the planes of the general faces of the cut glass sheet. The angle made by the oblique generatrix of the cut singing with the plane orthogonal to the general faces of the glass is called the break angle, which is actually different from 90 °. This breaking angle is not conceivable in the case of a usual glass spacer 15 mm thick, the surface to be made integral with the glass sheets to be perfectly parallel to the glass sheets.
Also, the current spacers glass insulating glass are obtained from the waterjet cutting technique so as to ensure a surface of association with the glass sheets perfectly parallel to the glass sheets (thus a perfectly orthogonal surface to the other faces of the spacer)
However, this technique by cutting with water jet has some disadvantages: - it requires manufacturing upstream specific glass thicknesses of 15 mm (precisely 14.7 mm); - It is complex handling, takes time and implements specific technical means within a working environment that must also be adapted to these means; it generates a rough surface condition due to jet marks; the faces of the spacer cut out are those found at the level of the edge of the glazing and the gas blade, because the other faces that have not undergone cutting are those intended to be associated with the glass sheets by their surface perfectly smooth. However, the rough faces that are those found transversely to the glass sheets create a matte appearance of the glass surface, not providing the desired transparency effect when we look at the glazing slightly in perspective The invention therefore aims to produce an insulating glazing, particularly for climatic furniture which obviates the various disadvantages mentioned above, by choosing a glass spacer which facilitates the manufacturing process of the spacer and the resulting insulating glazing, which makes it possible to gain even more in view of the glazing, while ensuring the desired sealing, and has the additional advantage of further reducing the thermal bridges.
According to the invention, the insulating glazing unit for an opening of a chamber / climatic cabinet, in particular a refrigerated cabinet, comprises at least two glass sheets (substantially parallel), spaced apart by at least one air or gas space, at least a transparent glass spacer arranged at the periphery of the glass sheets and now spaced and parallel the two glass sheets, and transparent adhesive fixing means fixing the spacer to each glass sheet by two of its opposite faces called faces of fixation, and is characterized in that the glass spacer has a thickness of less than 8 mm, in particular of thickness between 4 and 6 mm, and in that the adhesive fixing means consist of a transparent material arranged to the outer junction of the spacer and the glass sheets and having crept into the possible asperities of the glass of the fixing faces of the spacer.
The term "external" in the following description, which is outside the volume in contact with the gas blade, this volume is instead described as "internal".
Transparency is understood in the expression "transparent spacer", which allows at least to see colors, shapes through, without necessarily being able to read a text behind the transparent spacer.
Advantageously, the spacer is derived from a cut sheet of glass in the raw state, and assembled with glass sheets directly in the raw state. It is called "raw" cutting, a cut that then undergoes no polishing or other mechanical action of surface change.
Such a reduced thickness of the spacer makes it possible to very strongly limit the visual impact of the spacer.
In addition, the thickness being reduced, its mass is also reduced, which generates a much lower thermal bridge than a conventional spacer of the prior art.
Moreover, despite the small thickness of the spacer, the spacer combined with the presence of the bonding material not only at the junction line of the spacer and the glass sheets but also in the asperities of the glass at the faces Fixing the spacer ensures the required mechanical strength with regard to the risk of shock that could suffer the insulating glass. The bonding material has a resistance adapted to the tensile stress, preferably the bonding material has resistance to tensile stresses greater than 2.2 MPa.
The glazing did not need to include a homogeneous bonding interface layer between the attachment faces of the spacer and the glass sheets, because the chosen gluing means make it possible to fill the glass surface defects generated during cut and divide sufficiently to secure the attachment.
According to one characteristic, the glass spacer is derived from the cutting of glass, in particular float glass, with a thickness of less than 8 mm, the cutting having been done preferably by the tracing-breaking technique, or by laser cutting .
The glass of the spacer is preferably a monolithic glass.
According to another characteristic, the glass spacer is derived from the cutting of glass whose thickness is that of the glass sheets constituting the glazing.
Therefore, the upstream step of preparing the glass spacer is simple, usual, operating under the same conditions as that of preparing the glass sheets, and therefore does not require the complex means of the prior art which use for example a cut by jet of water. The glass spacer of the invention is used and arranged between the glass sheets via its fixing faces which correspond to its cut edges, in the raw state after cutting without a finishing step such as by polishing said songs, the means fixing by gluing of the spacer to the glass sheets advantageously filling the roughness and unevenness of the cut glass edges.
Unexpectedly, the inventors have demonstrated that a thin glass spacer, combined with the bonding means having crept into the asperities of the attachment faces, is sufficient to ensure the attachment of the spacer to the glass sheets, and especially that the transparent bonding means by filling in the asperities ensure a continuity of the optical index of refraction of the spacer-bonding assembly, annihilating the visual impact of the asperities and defects present on the fixing faces generated by the cut, particular of splitting-trimming.
According to another characteristic, the adhesive fixing means consist of a transparent bonding material having a refractive index identical or close to that of the glass, which guarantees the continuity of the optical index through the glass sheets, spacer and gluing means, providing for a person looking slightly in perspective the glazing or even several windows joined to each other, a continuity of transparency without visual distortion.
The term "close to that of glass" for the refractive index, a tolerance of plus or minus 30% with respect to the index of glass.
The transparent bonding material is a material that crosslinks under ultraviolet (UV) or not, preferably rapidly (at most a few minutes).
The transparent bonding material has a viscosity suitable for dispersing by capillarity in the asperities present in the glass at the cut faces of the spacer, preferably a viscosity of between 300 mPa.s and 900 mPa.s, preferably the order of 600 mPa.s.
Advantageously, the transparent bonding material is chosen to also constitute a sealing barrier at least with water, and preferably with water and with gases and water vapor, in particular is made of acrylate resin or epoxy resin. As a preferred example, the transparent bonding material is an acrylate resin, such as the UV adhesive Verifix B 678 supplied by the company BOHLE which is crosslinkable under UV. This glue has an average viscosity (600 mPa.s), and offers good capillarity and watertightness, and gas and water vapor.
The adhesive fixing means have a thickness at the outer junction line of the spacer and each glass sheet of a few microns to 1 mm, preferably a few microns to 0.5 mm at most. The invention also relates to a method for manufacturing an insulating glazing unit of the invention, comprising a step of preparing the spacer and a step of assembling the spacer to the glass sheets, characterized in that preparation step consists in cutting at least one glass strip of width equivalent to that which must separate the glass sheets (for example 12, 15 or 20 mm) in a glass substrate with a thickness of less than 8 mm, in particular between 4 and 6 mm, and associate, preferably in the raw state, this glass strip via the cut edges, the glass sheets with gluing means whose material is able to flow in the interface between said carved edges of the spacer and the glass sheets, and in the asperities of the glass carved songs.
According to one characteristic, the preparation step comprises a cutting of several glass strips. These strips of glass will be used for the same glazing or several glazings.
According to one feature, the assembly step includes flattening a glass sheet, arranging the spacer along one side of the glass sheet by applying one of the cut edges of the strip. of glass against the generally accessible face of the glass sheet and close to the edge of the glass sheet, in particular at most 5 mm from the wafer, preferably at most 1 mm from the wafer, the temporary retention in place of the spacer (for example by means of clamps), the application of a transparent adhesive material to the outer joint of the spacer and the glass sheet, arrangement of the other glass sheet against the another cut edge of the spacer and parallel and perfectly opposite the first glass sheet, and applying the transparent bonding material to the outer joint of the spacer and the second glass sheet.
According to another characteristic, the glazing is a double glazing or triple glazing.
The glazing may advantageously be provided on its glass sheets with one or more low-emissive coating (s) and / or an anti-fog or anti-icing layer, thus avoiding usual heating means, which participates in energy saving.
Finally, the invention relates firstly to an opening comprising a glazing unit according to the invention, and secondly to a climatic cabinet, of the refrigerated cabinet type, comprising at least one opening or a glazing unit of the invention, or a plurality of windows joined vertically to each other, the transparent spacer (s) being arranged vertically in the mounted position of the glazing (s).
The present invention is now described with the aid of examples which are only illustrative and in no way limitative of the scope of the invention, and from the attached illustrations, in which: FIG. 1 illustrates a schematic perspective view of a facade of a refrigerated cabinet incorporating a plurality of glazings of the invention; FIG. 2 is a partial perspective view of a glazing unit of the invention; - Figure 3 is a sectional view of a spacer according to the invention; - Figure 4 is a partial sectional view of the glazing of the invention with the spacer of Figure 3 without the presence of the bonding means; - Figure 5 shows the view of Figure 4 with the bonding means, which constitutes the glazing of the invention.
The figures are not scaled for easy reading.
The climate cabinet 1 schematically illustrated in Figure 1 comprises a plurality of openings 2 each comprising an insulating glazing unit 3 according to the invention.
The piece of furniture is for example a cold refrigerated furniture positive intended to be installed along a store aisle. One can thus constitute according to the invention a piece of furniture with a whole row of openings abutting laterally to each other vertically according to their edge.
In the case of a piece of furniture / a positive cold showcase, the seal being less critical than for a negative cold cabinet, the opening of the invention comprising the insulating glass of the invention does not need to understand vertical uprights frame and provided with thick joints at the junction of two openings / glazing abutments. The glazing of the invention thus allows the transparency of its vertical edges to provide a continuous transparent surface when the windows are joined by their edge.
Each insulating glazing unit comprises at least two glass sheets held parallel spaced apart by a frame whose vertically opposed parts in the mounted position of the glazing are transparent.
The facade of the glazing and therefore the furniture is thus purified of any structural frame and has a smooth glass wall. We gain in this way in vision space.
Only the transparent vertical part of the frame of the glazing and corresponding to the invention will be described below, the horizontal parts being generally formed by conventional means of spacer and sealing means which are not transparent. Similarly, will not be described the opening which incorporates the glazing, the hinge means, the support profiles and cache hinge means, the type of handle.
FIG. 2 illustrates a partial perspective view of the insulating glazing unit 3 showing the transparent vertical interior part 4 of the frame. The insulating glazing shown is double glazed with two sheets of glass. In the case of triple glazing with three sheets of glass, the glazing would comprise two transparent portions 4 of the invention.
The glazing 3 comprises two sheets of glass 30 and 31 parallel and spaced apart by means of an intermediate element or spacer 5.
The glass sheets 30 and 31 are preferably tempered glass. The thickness of each of the glass sheets 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 glass sheets are separated from each other by the spacer 5 to form between them a volume forming a gas blade 32.
The gas strip 32 has a thickness of at least 4 mm and is adapted according to the desired performance of the thermal transfer coefficient U, without however being greater than 16 mm, or even 20 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. The spacer 5 is entirely made of glass. The spacer 5 is of generally parallelepipedal shape and comprises four faces, a so-called internal face 50 facing the gas strip, an opposite outer face 51 facing the outside of the glazing and two faces called attachment face 52 and 53 facing the respective glass sheets 30 and 31. The spacer 5 extends in length, here not shown, along the entire length of each of the at least vertical sides of the glazing for the intended application of refrigerated furniture. The spacer has a width, transverse dimension to the general faces of the glass sheets, equivalent to the desired spacing of the glass sheets.
According to the invention, the spacer 5 has a thickness, a distance separating the inner and outer faces 50 and 51, which is less than 8 mm, preferably equal to the thickness of a conventional glass sheet for insulating glazing, ie 4 or 6 mm. The spacer 5 is fixed by gluing via its external connecting lines 54 and 55 connecting the attachment faces 52 and 53 and the respective inner faces 30A and 31A of the glass sheets 30 and 31.
According to the invention, the glass spacer is derived from the cutting of glass, in particular float glass used to manufacture the glass sheets of a glazing unit.
Preferably, the cutting of the spacer is carried out by the tracing-breaking technique. This upstream step of the manufacturing process of the insulating glazing unit of the invention makes it possible to advantageously be produced under the same conditions as those for cutting the glass sheets. The spacer illustrated in FIG. 3 has a thickness of 4 mm, equal to that of the glass sheets 30 and 31. Since it is derived from float glass, its perfectly parallel opposed faces will correspond to the inner and outer faces 50 and 51 in the assembled position. of the spacer, while the cut edges of the glass will correspond to the fixing faces 53 and 54.
By the cutting technique, the edges 52 and 53 are not perfectly flat as illustrated in Figure 3, but have flatness defects usually called splices, with asperities 56 which are amplified in the figure for understanding. The asperities have very small dimensions, of the order of 0.5 mm or less.
According to the invention, the spacer is assembled to the glass sheets in the raw state after cutting, as shown in Figure 3, without polishing finishing step said songs.
FIG. 4 is a schematic sectional view of the glazing unit of the invention with the spacer of FIG. 3, without the presence of the bonding means to better perceive the unevenness of the spacer and the surface of the fixing faces. is not perfectly smooth and parallel to each of the inner faces 30A and 31A of the glass sheets.
According to the invention, the gluing means 6 illustrated in FIG. 5 are such that they are arranged at the junction lines 54 and 55 of the external face of the spacer and the glass sheets, and in the asperities 56 fixing faces 52 and 53 of the spacer.
The gluing means 6 are made of a material capable of flowing during its deposition on the glass. In particular, the material has a viscosity of between 300 mPa.s and 900 mPa.s.
Thus, the thickness of material disposed on the joining lines 54 and 55 is minimized, in particular does not exceed 1 mm, preferably does not exceed 0.5 mm, on the faces of the glass sheets at said lines join. In addition, the material is arranged at the interface of the fixing faces 53 and 54 and the faces 30A and 31A of the glass sheets, by filling the asperities 56, so as to achieve an extremely thin coating of gluing almost imperceptible to the naked eye.
The material of the bonding means 6 is a transparent bonding material having a refractive index identical to or close to that of the glass.
The material is able to crosslink quickly. It crosses for example under ultraviolet.
The material of the gluing means consists of a material having sealing properties at least with water, and preferably with water and with gases and water vapor, in particular consists of acrylate resin or epoxy resin
The bonding material taken for the example of the invention (not limiting) and combining all the above properties is an acrylate resin, the UV Verifix B 678 glue supplied by the company BOHLE.
The manufacturing process of the glazing of the invention is as follows with regard to the manufacture of the spacer and its assembly: - Cutting of several glass strips in a glass substrate of 4 or 6 mm thick by the technique of tracing-breaking, the glass strips corresponding to the separation width of the glass sheets of the glazing unit; - Preferably, transverse cutting of each glass strip at the ends of the beginning and end of cutting strips; Transverse cutting of a strip at the desired length to make the spacer, the length corresponding to the length of one side of the glazing unit; - Flattening of a first sheet of glass; - Arrangement of the spacer on the inner face of the glass sheet via one of the longitudinal cut edges of the glass strip; - Temporary maintenance of the spacer, for example by a clamp; - Deposition of the bonding means at the joint line of the spacer and the glass sheet on the outer side of the spacer, creep of the bonding means in the asperities; - Drying of the glue for example by ultraviolet if the gluing means are crosslinkable to ultraviolet; - Arranging the second glass sheet perfectly opposite and parallel to the first glass sheet and affixing it to the second cut edge of the spacer; - Temporary maintenance of the glass sheet, for example by clamps; - Deposition of the bonding means at the joint line of the spacer and the second glass sheet on the outer side of the spacer, creep of the bonding means in the asperities; - Drying the glue; - Withdrawal of means of temporary maintenance.
Therefore, the method of the invention is simple to implement, uses the conventional cutting technique of thin glass, and the spacer of the invention thus produced in the raw state, combined with the bonding means, allows to produce an insulating glazing whose spacer is transparent, very thin, with gluing means imperceptible to the naked eye, which does not disturb the transparent visual impression that one must have of the whole of the glazing.
