IMPROVED WINDOW WITH THERMOACOUSTIC INSULATION

Description

TECHNICAL FIELD

[0001] The present invention relates to the field of glazed openings in building facades, and more particularly to a window for improving thermal and acoustic insulation performance. The present invention finds a particularly advantageous, though not limiting, application in the case of a sliding or casement window with multiple panes of glass, for example, double glazing. STATE OF THE ART

[0002] Conventionally, a window frame, whether hinged or fixed, is formed by extruding profiles and, in conjunction with the glazing, serves to create an airtight, watertight, and windproof barrier between the interior and exterior environments. The objective is to provide, in particular, satisfactory thermal and acoustic insulation.

[0003] The geometric configuration of a window, constructed using such profiles, is essentially generic regardless of its operating mode (sliding, casement, etc.). The glazing is set within the opening sash, thus forming a fixed bond with it. The fixed sash, for its part, is positioned peripherally around the opening sash, notably to support it. According to this traditional configuration, the fixed sash defines a central plane within which the opening sash and the glazing extend.

[0004] This configuration means that the opening and fixed frames have peripheral surfaces at their respective mullions and transoms, forming a frame that is substantially parallel to the average plane. Since these surfaces overlap very little, they are largely exposed to the interior and exterior environments, thus creating sensitive areas prone to heat exchange and air infiltration. This heat exchange negatively impacts the window's thermal and acoustic performance. To address this, various solutions have been considered, sometimes in combination to maximize their respective effects.

[0005] It should be noted that the term "thermoacoustic window" can be used in the prior art to refer to a window obtained through the implementation of solutions designed to achieve enhanced thermal and acoustic performance. This interpretation is maintained throughout the description using the same terminology.

[0006] Thus, initially, it is possible to modify the material and internal structure of the profiles. For example, profiles made of metal (aluminum) can be used. Since their thermal performance is only average, plastic elements are typically inserted into internal cavities within the profiles to create a thermal break. Alternatively, profiles made of thermoplastic materials, such as PVC (Polyvinyl Chloride), can be used. PVC offers superior thermal performance compared to aluminum, but at the expense of mechanical strength.

[0007] Finally, as a second step, it is also possible to modify the glazing itself to impact thermal and acoustic insulation. Thus, certain glazing parameters (glass thickness, number of panes, presence or absence of a gas gap, etc.) can be varied to improve insulation characteristics.

[0008] However, despite the implementation of such solutions, thermoacoustic windows built using a traditional configuration still offer limited performance. This is because the peripheral surfaces of the opening and fixed frames remain fundamentally exposed in their entirety to the interior and exterior environments.

[0009] It should be noted that it is also possible to vary the profile thickness (the thickness here referring to the distance perpendicular to the glazing). However, such a solution remains problematic since only a substantial increase in thickness allows for a significant impact on insulation performance. This runs counter to increasingly minimalist on-site installation constraints, as well as the need to control manufacturing costs.

[0010] More recently, thermoacoustic windows designed so that the opening sash is concealed within the fixed frame have also been proposed. With such a design, only the fixed frame is exposed to the interior and exterior environments, thus reducing the exposed sensitive areas. However, sufficient areas still remain for thermal and acoustic insulation to be suboptimal. Typically, thermal insulation achieves a Uw value of around 1.4 W / m².K when the window is fitted with double glazing (or even 0.8 W / m².K in the case of triple glazing). Acoustic insulation, on the other hand, has a best-case scenario RA,tr value of around 42 dB (RA,tr corresponding to sound insulation from road traffic) in the case of triple glazing. Such values ​​are not optimal.

[0011] Moreover, these recent constructions are complex to manufacture and implement, requiring significant work in shaping the profiles, and ultimately resulting in a high production cost. DESCRIPTION OF THE INVENTION

[0012] The present invention aims to overcome all or part of the drawbacks of the prior art, particularly those described above, by providing a solution that allows for a window with excellent thermal and acoustic insulation performance, and which is also simple in design, both during its manufacture and during its assembly and installation in a wall opening. A window can close an opening in any type of wall, including a wall separating an interior environment from an exterior environment.

[0013] To this end, and according to a first aspect, the invention relates to a window comprising an opening frame, a fixed frame, glazing that cooperates in a fixed manner with said opening frame, and means for moving the opening frame relative to the fixed frame when opening / closing the window. A frame, whether fixed or opening, is, in a manner known per se, formed by an assembly of profiles, of the mullion or transom type, for example, with a mitered or straight cut.

[0014] Furthermore, the opening frame and the means of movement are arranged between the glazing and the fixed frame, so that the window, when closed, forms a multi-layered structure exhibiting: a height and width substantially identical to the corresponding dimensions of the glazing, a thickness at least equal to the sum of the respective thicknesses of the glazing and of the opening and fixed frames.

[0015] In particular embodiments of the invention, the window may further comprise one or more of the following characteristics, taken individually or in all technically possible combinations.

[0016] In a particular embodiment, the glazing is superimposed on the opening frame so that their respective peripheral edges are aligned.

[0017] In a particular embodiment, the respective peripheral edges of the fixed and opening frames are aligned when the window is closed.

[0018] In a particular embodiment, the peripheral edge of the fixed frame extends substantially beyond the peripheral edge of the opening frame when the window is closed, so as to define, opposite the opening frame, a peripheral extension of said fixed frame, the window having a peripheral cover configured so that, when the window is closed: cooperate edge to edge with said peripheral extension, extend in a direction normal to the glazing at least to an internal face of the glazing superimposed on the opening frame, achieve thermal insulation at least along said normal direction.

[0019] In a particular embodiment, the peripheral hood extends to an external face of the glazing, said external face being opposite said internal face in a direction normal to the glazing.

[0020] In a particular embodiment, the window is of the sliding type with a tilting mechanism, said means of movement comprising: an "intermediate" piece arranged between the opening and fixed frames, and movable in translation in a direction normal to the glazing, so as to translate the opening frame in the same direction, hardware configured to translate said intermediate piece, sliding guides arranged on said intermediate piece, the opening frame cooperating with said sliding guides for sliding in a direction parallel to the glazing, said means of movement being further configured so that the translational movement normal to the glazing is prior to the sliding parallel to the glazing when opening the window, and vice versa when closing the window.

[0021] In a particular embodiment, said intermediate piece is a frame of shape and dimensions substantially identical to the opening and fixed frames, and arranged so that the respective peripheral edges of the opening frame, the fixed frame and said intermediate piece are substantially aligned when the window is closed.

[0022] In a particular embodiment, the fixed frame comprises an external face, arranged opposite the opening frame when the window is closed and comprising a peripheral groove extending in the opposite direction to the glazing, said intermediate piece having, in cross-section, a substantially L-shaped form formed by a first arm and a second arm, such that: said first branch is configured to cooperate with said peripheral groove during said translational movement normal to the glazing, said second branch supports said sliding guides and is configured to bear against the opening frame during said translational movement normal to the glazing.

[0023] In a particular embodiment, said hardware is of the compass type connecting the intermediate piece to the fixed frame.

[0024] In a particular embodiment, the window is of the sliding type, said means of movement comprising sliding guides arranged on the fixed frame and configured to allow the opening frame to slide in a direction parallel to the glazing.

[0025] In a particular embodiment, the window is of the casement type, the movement means being arranged between the opening and fixed frames, and configured to form an axis of rotation of the opening frame when opening / closing the window.

[0026] In a particular embodiment, the glazing is at least double glazing, preferably triple glazing.

[0027] In a particular embodiment, the fixed cooperation of the glazing with the opening frame is achieved by adhesive means covering at least partially an external face of said opening frame, said external face being arranged opposite the glazing.

[0028] According to a second aspect, the invention relates to a pre-assembled set, or kit, comprising profiles for assembling an opening frame, profiles for assembling a fixed frame, as well as means of movement, so as to allow the construction of a window according to the invention.

[0029] According to a third aspect, the invention relates to a method for sealing an opening in a wall separating an external environment from an internal environment. This method comprises the steps of: to obtain a kit according to the invention, to assemble a window in the wall opening using said kit.

[0030] In a particular mode of implementation, the window assembly step in the wall opening is carried out so that the glazing faces the interior environment. PRESENTATION OF THE FIGURES

Figures 2a to 2c : a schematic representation of an alternative implementation of the window figures 1a to 1f , and corresponding to a cross-sectional view following respectively closed, open translated and open sliding positions of said window.

[0032] In these figures, identical references from one figure to another designate identical or analogous elements. For clarity, the elements shown are not to scale unless otherwise indicated. DETAILED DESCRIPTION OF IMPLEMENTATION METHODS

[0033] The present invention relates to the design of thermoacoustic windows for sealing an opening in a wall (not shown in the figures), such as a building wall. Such a wall separates an interior environment 10, such as a living space within the building, from an exterior environment 20, such as a road. However, following other examples not detailed here, there is nothing to preclude having a window located differently, for example, within a living space itself.

[0034] THE figures 1a, 1b and 1cschematically represent an example of the realization of a window 100 in the open position, and correspond respectively to a front, top and three-quarter view of said window 100.

[0035] THE figures 1d, 1e and 1f represent respectively window 100 of the figures 1a, 1b and 1c when it is in the closed position.

[0036] The following description applies more specifically, but not exclusively, to a window 100 extending in a midplane and having a substantially rectangular shape when viewed from a direction normal to said midplane. However, nothing precludes considering a window with a different general shape, for example, circular, oblong, etc., with reference, for instance, to a porthole-type window. Indeed, the embodiments described below apply equally well to a non-rectangular window, without requiring any structural adjustments. Even if structural modifications were necessary, without departing from the scope of the invention, a person skilled in the art would be able to implement them.

[0037] Window 100 has an opening frame 110 and a fixed frame 120.

[0038] In the present embodiment, each frame 110, 120 is parallelepiped in shape and, in a manner known per se, formed by assembling profiles, such as uprights or rails, for example, with mitered or straight cuts. Furthermore, each profile is made by extruding a predetermined material, for example, aluminum or PVC. However, nothing precludes frames made from other materials, as the type of material used is not a limiting factor for the construction of the window according to the invention.

[0039] As illustrated in the figures 1a to 1fEach frame 110, 120 comprises an inner face 111, 121 and an outer face 112, 122, designed to be arranged respectively with respect to the interior environment 10 and the exterior environment 20, and to extend in the mid-plane of the window 100. Each face 111, 121, 112, 122 has a peripheral edge defined as the boundary beyond which the frame 110, 120 does not extend towards the wall. In this embodiment, the peripheral edge of a face is rectangular when viewed along a direction normal to the mid-plane of the window 100. It should be noted that the peripheral edge of a face 111, 121, 112, 122 is formed of several parts positioned respectively at the stiles and rails of the frame 110, 120 supporting said face. In addition, each face 111, 121, 112, 122 of a frame 110, 120 has an internal edge, also rectangular in shape and opposite to said peripheral edge of said face.The distance between the peripheral and internal edges of a face 111, 121, 112, 122 is determined according to, in particular, the mechanical strength required as well as the aesthetic appearance of the window 100.

[0040] For example, the numerical references 121p and 121i illustrated in the figure 1c relate respectively to the peripheral edge and the internal edge of the internal face 121 of the fixed frame 120.

[0041] The window 100 also includes a glazing unit 130 that cooperates with the opening frame 110 when the window 100 is opened or closed. The glazing unit 130 is intended to form a partition between the interior 10 and exterior 20 environments, its structure being in no way limited within the scope of the present invention. For example, it may be single glazing, preferably double glazing, and even more preferably triple glazing. As is known, the number of panes of glass used in the glazing unit, as well as their respective thicknesses and the presence of inert gas gaps separating them, are parameters that a person skilled in the art can adjust according to the desired effect in terms of thermal and / or acoustic insulation.

[0042] As illustrated, but not limited to, the figures 1a to 1fThe glazing 130 forms a flat surface of predetermined thickness defining a plane called the "glazing plane". This glazing plane extends in the average plane of the window 100. In a manner analogous to the configuration of the opening frame 110 and fixed frame 120, the glazing 130 is parallelepiped in shape, and has two faces respectively internal 131 and external 132, each of said faces 131, 132 being delimited by a peripheral edge of rectangular shape.

[0043] The concepts of width and height are defined in relation to the corresponding dimensions of the 130 glazing. For example, with reference to the figure 1a The width is measured in the direction in which the lower part of the peripheral edge of the outer face 132 of the glazing 130 extends. The height is measured in the direction perpendicular to that of the width, in the plane of the glazing 130. In the example of the figure 1aThe width of the glazing is less than its height. However, nothing prevents having glazing whose width is greater than its height, or even square glazing.

[0044] The concept of thickness corresponds to a distance measured in a direction normal to the plane of the glazing 130, and therefore ultimately to the average plane of the window 100.

[0045] Finally, a section is said to be transverse when it is made along a plane normal to both the glazing 130 and the uprights of the opening frame 110 and fixed frame 120.

[0046] The window 100 also includes means for moving the opening frame 110 relative to the fixed frame 120 during the opening / closing of said window 100. These means of movement characterize the type of window. For example, the window 100 illustrated in the figures 1a to 1fis of the sliding type. By "sliding window," we are referring here to a window 100 whose opening movement is broken down into two stages: a first step during which the opening frame 110 moves in translation in a direction normal to the glazing 130, to move away from the fixed frame 120, a second step during which the opening frame 110 slides in a direction parallel to the plane of the glazing 130. When window 100 is closed, the order of the sequence of said first and second steps is reversed.

[0047] However, nothing precludes having a window of another type, that is to say, with a different opening / closing mechanism. This aspect of the invention is addressed in alternative embodiments described later; the remainder of the description refers, unless otherwise stated, to the aforementioned sliding window 100.

[0048] The opening frame 110 and the means of movement are arranged between the glazing 130 and the fixed frame 120, so that the window 100 forms, when closed, a multi-layered structure.

[0049] This multilayered structure has a height and width substantially identical to the corresponding dimensions of the glazing 130. By "substantially identical," we mean here that any difference between the width (respectively the height) of the glazing 130 and one of the frames 110, 120 is much smaller than the characteristic dimensions of the glazing 130. Typically, such a difference is on the order of a centimeter, preferably at most 1 cm in the context of the present invention. Thus, when the window 100 is assembled but not yet installed in the opening, and is observed from a distance of a few meters, for example 5 meters, the multilayered structure of the window 100 gives it a parallelepiped appearance, such that it is not possible to distinguish whether the respective widths and heights of the opening frame 110, fixed frame 120, and the glazing 130 differ.

[0050] In addition, the multi-layered structure formed by the window 100 when closed also has a thickness at least equal to the sum of the respective thicknesses of the glazing 130 and the opening frame 110 and fixed frame 120. For example, the thicknesses of the glazing 130 and the opening frame 110 and fixed frame 120 are respectively at least 6mm, 20mm and 20mm, so that the thickness of the window 100 is at least 46mm.

[0051] Thus, by "multilayer structure", we refer here to the fact that the window 100 forms, when closed, a single block, obtained by superimposing, in a direction normal to the glazing 130, the opening frame 110 and fixed frame 120, as well as the glazing 130. In this way, when observing the closed window 100 in a direction normal to the glazing 130, the fixed frame 120 is hidden behind the opening frame 110, which is itself hidden behind the glazing 130.

[0052] This configuration of window 100 is particularly advantageous because it allows for excellent thermal and acoustic insulation performance. Indeed, the opening frame 110 and fixed frame 120 are positioned behind the glazing 130, which almost completely obscures them. Therefore, by obscuring the frames 110 and 120, the glazing 130 forms a barrier to thermal and acoustic exchange at the level of the frame structure itself, more precisely at their respective internal faces 111 and 121 and external faces 112 and 122. More specifically, with regard to acoustic insulation, it is understood that the glazing 130 vibrates before the window assembly formed by the opening frame 110 and fixed frame 120.

[0053] It is therefore important to note that such a multi-layered structure differs fundamentally from previously known window structures. Indeed, in prior art, windows intended to close an opening in a wall were not constructed on the basis of such a stacking of frames and glazing. On the contrary, the frames of these windows were configured to form sashes, that is, structural elements with grooves for interlocking. Typically, the glazing is set within the opening sash, which may itself be set within the fixed sash, for example, in the case of a sliding window.

[0054] In summary, the multi-layered structure of the window 100 according to the invention therefore forms an arrangement of the frames 110, 120 and the glazing 130 which stands out radically from the existing one, and which advantageously allows to take advantage of the insulation of the glazing 130 not only at the level of the daylight, but also especially at the level of the opening frames 110 and fixed frame 120. This results in excellent thermal and acoustic insulation performance.

[0055] Furthermore, such a multi-layered structure also simplifies the design of window 100. Indeed, since the glazing 130 insulates not only at the daylight level but also at the frame levels 110 and 120, it is clear that the frame profiles do not need to be complexly manufactured. Thus, no thermal break is required to achieve excellent thermal and acoustic insulation. For example, when the profiles are made of aluminum, it is not necessary to crimp polyamide strips into the internal structure of the profiles, or even between the profiles themselves. That being said, it will be clear that the invention in no way precludes the use of more complexly manufactured profiles, such as those with thermal breaks.

[0056] Furthermore, it is understood that the use of simplified manufacturing profiles facilitates the assembly of window 100, as the joining operations between the profiles of a frame 110, 120 are less complex and less time-consuming. Moreover, assembling window 100 to obtain the multi-layered structure is also simple, as it consists of stacking the frames 110, 120 and the glazing 130, unlike the interlocking techniques previously used in the prior art.

[0057] Such a window, when it closes an opening in a wall separating an interior environment from an exterior environment, is also advantageously configured to withstand environmental stresses, in particular weathering (water, air, wind...) and solar radiation.

[0058] For the remainder of this description, we adopt the convention that the concept of alignment of peripheral edges belonging to different elements (opening frame 110, fixed frame 120, glazing 130) refers to peripheral edges that coincide when the window 100 is viewed from a direction normal to the glazing. In other words, aligned edges are arranged in the same plane.

[0059] In a particular embodiment, the glazing 130 is superimposed on the opening frame 110 so that their respective peripheral edges are aligned. Thus, the glazing 130 completely covers the opening frame 110, so that no part of said opening frame 110 extends beyond the peripheral edge of the glazing 130. Consequently, the glazing 130 forms a complete thermal and acoustic barrier for the opening frame 110. In this way, the opening frame 110 no longer constitutes a weak point in the thermal and acoustic insulation performance of the window 100. Indeed, the inner face 111 and outer face 112 of the opening frame 110 are entirely positioned behind the glazing 130, so that the thermal and acoustic exchanges that could affect these faces 111, 112, as is conventionally the case in the prior art, are here greatly reduced, or even non-existent depending on the quality of the glazing 130.

[0060] In a preferred embodiment, illustrated without limitation by the figures 1b, 1c , 1st and 1stThe respective peripheral edges of the fixed frame 120 and the sash 110, as well as the glazing 130, are aligned when the window 100 is closed. In this configuration, the glazing 130 completely obscures the fixed frame 120 and the sash 110. In other words, when the window 100 is viewed from a direction normal to the glazing, only the glazing 130 is visible, the sash 110 and fixed frame 120 being hidden behind it. It is clear that the glazing 130 then forms a complete thermal and acoustic barrier not only for the sash 110, but also for the fixed frame 120, thus enabling optimal thermal and acoustic insulation performance. For example, for thicknesses such as those mentioned above, and when window 100 is fitted with conventional double glazing (Ug coefficient equal to 1.1 Wm -2< .K -1< ), a Uw coefficient of 1.2 Wm -2< .K -1< is achieved.In the preferred case of triple glazing (Ug coefficient of 0.5 W / m².K), a very advantageous Uw coefficient of 0.55 W / m².K is achieved. Regarding sound insulation, an RA,tr coefficient of 45 dB is achieved, for both double and triple glazing.

[0061] However, it is possible that the multi-layered structure may be configured so that the respective peripheral edges of the fixed frame 120 and the sash 110 are aligned when the window is closed, but that these edges extend significantly beyond the peripheral edge of the glazing 130. It is also possible that the respective peripheral edges of the sash frame 110 and the glazing 130 are aligned, and that only the peripheral edges of the fixed frame 120 extend significantly beyond them. It should then be noted that the fact that the respective peripheral edges of the frames 110, 120, and the glazing 130 are not perfectly aligned depends, on the one hand, on manufacturing tolerances of the window components 100, and on the other hand, on any tolerances that may be necessary for installing the window 100 in the wall opening.Nevertheless, the inventors observed that the differences in width and height between the frames 110, 120, and the glazing 130 are, as mentioned above, typically no more than 1 cm. Such differences do not affect the effect achieved by the invention, namely, providing excellent thermal and acoustic insulation performance. In particular, the insulation results obtained when the edges of the different layers of the window 100 are not perfectly aligned are only slightly lower than the optimal results given above, and in all cases superior to those of the prior art.

[0062] The glazing 130 cooperates in a fixed manner with the opening frame 110. By "fixed cooperation", we refer here to the fact that the glazing 130 follows the opening or closing movement of the opening frame 110. For this purpose, the inner face 131 of the glazing 130 is superimposed on the outer face 112 of the opening frame 110, said fixed cooperation being carried out between these faces.

[0063] In a preferred embodiment, the fixed interaction of the glazing 130 with the opening frame 110 is achieved by means of adhesives covering at least partially the outer face 112 of said opening frame 110, said outer face 112 being positioned opposite the glazing 130. These adhesives are, for example, double-sided tape. In another example, the adhesives are an adhesive substance, that is to say, a synthetic material enabling two surfaces to adhere without wetting. This adhesive substance is characterized, in particular, by a tackiness selected from a predetermined range of values ​​so as to allow the glazing 130 to remain fixed in contact with the opening frame 110.The properties of adhesive substances are well known to the person skilled in the art who will be able to choose, in particular from the catalogue of products offered by specialized manufacturers, a range of adhesives with compositions adapted to the characteristics of window 100 according to the invention.

[0064] In an even more preferred embodiment, the adhesive means completely cover the external face 112 of the opening frame 110.

[0065] However, nothing precludes having a fixed cooperation achieved by means other than fixed means, for example by a clamp fixing maintaining the glazing 130 in contact with the external face 112 of the opening frame 110. Or, for example, when the glazing 130 comprises several panes, by means of a clamp arranged in an intercalary space between panes in order to lock the glazing 130 against the external face 112 of the opening frame 110. A person skilled in the art knows how to implement such examples of implementation without difficulty.

[0066] Such a fixed bond between the glazing 130 and the opening frame 110 contributes to the realization of the window 100 as a multi-layered structure, and thus ultimately contributes, as previously described, to the excellent insulation performance. It should nevertheless be noted that a fixed bond using adhesives remains preferable, as it contributes advantageously to achieving optimal acoustic performance, especially when the adhesives cover a significant portion of the external face 112 of the opening frame 110. Indeed, such adhesives make it possible to increase the sound insulation effectiveness of the window 100 in the high-frequency range, typically between 1000 Hz and 5000 Hz (for example, for high-speed traffic noise or an alarm siren), by reducing the risk of vibrational resonance of the glazing 130 in this range.

[0067] The remainder of the description relates more specifically to the means of moving the 100 sliding tilting window illustrated, without limitation, by the figures 1a to 1f .

[0068] The movement means include an "intermediate" piece 140 arranged between the opening frame 110 and the fixed frame 120, and movable in translation in a direction normal to the glazing 130, so as to translate the opening frame 110 in the same direction. In other words, the intermediate piece 140 is configured to perform the first step of the opening mechanism of the sliding window 100.

[0069] In a particular embodiment, said intermediate piece 140 is a frame of shape and dimensions substantially similar to the opening frame 110 and fixed frame 120.

[0070] For example, and as illustrated in the figures 1a, 1b, 1c , 1st and 1stThe intermediate piece 140 is a parallelepiped-shaped frame whose dimensions are substantially identical, preferably identical, to the respective dimensions of the opening frame 110 and fixed frame 120, as well as the glazing 130. According to this example, the intermediate piece 140 also has an internal face 141 (respectively an external face 142) arranged opposite the external face 122 of the fixed frame 120 (respectively the internal face 111 of the opening frame 110). Consequently, the intermediate piece 140 is positioned behind the glazing 130, sandwiched between the opening frame 110 and fixed frame 120, and such that the respective peripheral edges of the opening frame 110 and fixed frame 120, as well as of the intermediate piece 140, are substantially aligned, preferably aligned, when the window 100 is closed. The said intermediate piece 140 thus forms an additional layer of the multilayer structure of the window 100.We note then that the thickness of the window 100 is in this case equal to the sum of the respective thicknesses of the glazing 130, the opening frames 110 and fixed frame 120, as well as the intermediate piece 140.

[0071] However, nothing excludes having an intermediate piece 140 in the form of a frame and having width and height dimensions that are significantly different from the corresponding dimensions of the opening frames 110 and fixed frames 120 as well as the glazing 130, following technical considerations similar to those described above (differences typically of at most 1cm).

[0072] The means of movement also include a hardware 150 configured to translate said intermediate piece 140. It is understood that the hardware supports the intermediate piece 140 and the opening frame 110.

[0073] In a particular embodiment, the hardware 150 is of the compass type, connecting the intermediate piece 140 to the fixed frame 120. Such hardware 150 is configured to move said intermediate piece 140. For example, and as illustrated in the figures 1b and 1cEach mullion of the intermediate piece 140 is connected by a stay 150 to the mullion of the fixed frame 120 opposite it. Such a stay 150 has, in a manner known per se, a V-shape formed by two movable arms rotating about a common axis of rotation. For example, the axis of rotation of a stay is arranged at the respective ends of the two arms, which overlap at the axis of rotation. The axis of rotation is further fixed to a mullion of the intermediate piece 140 so that the stay 150 extends in a plane normal to the glazing 130 and parallel to the mullion. The arms of the stay 150 also have respective ends opposite those overlapping with the axis of rotation, these ends being fixed to the mullion of the fixed frame 120 opposite it. Such arrangements allow a translational movement of said intermediate piece 140 in a direction normal to the glazing 150.

[0074] However, there is nothing to preclude other configurations for the 150 hinges of the movement mechanisms. For example, as an alternative to installing 150 hinges at the respective stiles of the fixed frame 120 and the intermediate piece 140, said 150 hinges are arranged to cooperate with the respective rails of the fixed frame 120 and the intermediate piece 140. Alternatively, 150 hinges are arranged at the stiles and rails. Furthermore, there is nothing preventing the use of 150 hinges with a different shape, for example, a cross shape. Generally speaking, a person skilled in the art knows how to select suitable hardware for the movement of the intermediate piece 140 from the product catalogs offered by specialized manufacturers.

[0075] The means of movement also include sliding guides 160 arranged on said intermediate piece 140 and configured to allow the opening frame 110 to slide in a direction parallel to the glazing 130. For example, and as illustrated in the figure 1c The sliding guides 160 are formed by two slides of a type known per se, which form rails. These slides 160 are fixedly arranged on the outer face 142 of the intermediate piece 140, at the level of the lower and upper crossbars. According to this example, the slides 160 extend along the entire length of the crossbars so as to allow the window 100 to open fully. Each slide 160 has a groove 161 with which a tab 113, projecting from the inner face 111 of the opening frame 110, engages in sliding motion. This tab is, for example, integral with the opening frame 110.

[0076] However, nothing precludes having 160 slides extending over a shorter distance, for example, half the length of the crossbars, so as to allow only partial opening of the window 100 by sliding. Nor does it preclude having sliding guides 160 configured differently, for example, as grooves machined directly into the mass of the intermediate piece 140.

[0077] Furthermore, and as illustrated in the figures 1a to 1c The sliding movement of the window 100 is lateral in a single direction. To this end, locking means of a type known per se, such as stop elements (not shown in the figures), cooperate with the ends of the slides 160, so as to block the sliding movement in the opposite lateral direction. Alternatively, the movement means are configured to allow lateral sliding in two opposite directions.

[0078] It will also be clear to those skilled in the art that the window 100 according to the invention is not limited to lateral sliding. Thus, sliding within the plane of the glazing 130 and along a vertical direction (from top to bottom) is also possible, for example by modifying the positions of the sliding guides 160.

[0079] It follows from the configuration of the means of movement that the translational movement normal to the glazing precedes the sliding parallel to the glazing 130 when the window 100 is opened, and vice versa when the window 100 is closed. In this way, the window 100 can be advantageously positioned within the wall opening so that, in the closed position, the glazing 130 is flush with one side of the wall, for example, the exterior side. In other words, according to this arrangement, the opening frame 110 and the fixed frame 120 are concealed within the thickness of the wall when the window 100 is closed, so that the exterior side of the wall has a smooth, aesthetically pleasing appearance, with only the glazing 130 remaining visible.When the window 100 is opened, the sliding translation movement first moves the glazing 130 away from the wall, towards the outside environment 20 following this example, and then translates the glazing 130 parallel to the wall, along the outside side.

[0080] It should be noted that the window clearly includes means for actuating the movement mechanisms, such as manual means, typically at least one handle (e.g., a handle integrated into the glazing), at least one rod, etc. Alternatively, these means are at least partially motorized to allow for automatic opening and closing without requiring any effort. Such means are not described in further detail as they fall outside the scope of the invention, and those skilled in the art will know how to select and arrange them.

[0081] The window 100 according to the invention is not, however, limited to a sliding opening / closing type, although this remains preferred because of its advantageous aesthetics (when the window is installed in the wall and closed) as well as because it allows, as is known to those skilled in the art, to improve ventilation in the interior environment 10.

[0082] Also, other configurations of the means of transport are conceivable in order to modify the way in which window 100 opens and closes.

[0083] According to another embodiment, the window is of the sliding type (not shown in the figures), said means of movement comprising sliding guides, for example slides, arranged on the fixed frame and configured to allow the opening frame to slide in a direction parallel to the glazing. Compared to the sliding window 100 according to the invention, and illustrated in the figures 1a to 1fThe opening frame is configured here to move only by sliding in a direction parallel to the plane of the glazing. It is therefore clear that, in this example, the movement mechanism does not include any intermediate parts or compass-type hardware. Furthermore, it is also clear that installing such a sliding window in the wall opening differs significantly from installing a tilt-and-slide window. Indeed, this sliding window is positioned so that the fixed frame is flush with one side of the wall, allowing the opening frame to lie in a plane parallel to, but distinct from, that side of the wall. In this way, the opening frame can slide freely.

[0084] According to yet another embodiment, the window is of the casement type (not shown in the figures), the movement means being arranged between the opening and fixed frames and configured to form at least one axis of rotation of the opening frame when the window is opened / closed. For example, the movement means include a hinge arranged to form a vertical axis of rotation. Preferably, the hinge is positioned within a recess in the outer face of the fixed frame, so as to remain concealed. The hinge is fixed within the recess in a manner known per se.

[0085] THE figures 2a, 2b and 2c schematically represent an alternative implementation of window 100 of the figures 1a to 1f , and correspond to a cross-sectional view following respectively closed, open translated and open sliding positions of said window 100. The figures 2a to 2cillustrate a cross-section taken at the level of the uprights of window 100, with only one upright shown. It is nevertheless clear that the arrangements described below apply to window 100 in its entirety by symmetry.

[0086] As illustrated in the figures 2a to 2c The window 100 is a sliding type. The peripheral edges of the fixed frame 120 extend substantially beyond the peripheral edges of the opening frame 110 when the window 100 is closed, so as to define, opposite the opening frame 110, a peripheral extension 123 of said fixed frame 120. The respective peripheral edges of the opening frame 110 and the glazing 130 are, however, aligned.

[0087] The window 100 has a peripheral cover 170 configured so that, when the window 100 is closed, it cooperates edge-to-edge with said peripheral extension. "Edge-to-edge cooperation" refers here to the fact that, in cross-section, said cover 170 extends a peripheral edge 124 of the fixed frame 120, said peripheral edge 124 joining the respective peripheral edges of the inner face 121 and outer face 122 of said fixed frame 120. As illustrated in the figures 2a to 2c , the width of the peripheral hood 170 is equal to the width of said peripheral extension 123.

[0088] Furthermore, the hood 170 is fixedly attached to the peripheral extension 123 by means of known fastening methods (adhesive, screws, etc.). However, nothing precludes a removable attachment between the hood 170 and the peripheral extension 123, for example, by embedding them.

[0089] Furthermore, the peripheral cover 170 is configured so that, when the window 100 is closed, it extends in a direction normal to the glazing 130 at least to the inner face 131 of the glazing 130 which is superimposed on the opening frame 110. Insofar as the peripheral extension 123 of the fixed frame 120 forms an offset with respect to the opening frame 110, said peripheral cover 170 makes it possible at least in part to fill said offset to obtain a window 100 in a parallelepiped block.

[0090] Finally, the cover 170 is configured so that, when the window 100 is closed, it provides thermal insulation at least along its normal direction. Thus, beyond aesthetically compensating for the offset created by the peripheral extension 123, the cover 170 advantageously reduces localized heat exchange at the level of said peripheral extension 123, which is not concealed by the glazing 130 and the opening frame 110. It should be noted, however, that such heat exchange has a minor impact on the performance of the window 100, due in particular to the small dimensions of the peripheral extension 123, for example, at most 1 cm. It is therefore clear that the peripheral cover 170 provides supplementary assistance to the thermal insulation performance of the window 100.

[0091] It is also noted that the additional thermal insulation provided by the hood 170 is all the better as the latter covers at least the opening frame 110. Thus, in a preferred example of implementation, the peripheral hood 170 extends to the external face 132 of the glazing 130.

[0092] To create a thermal barrier, the hood 170 is, for example, made of plastic material, preferably thermoplastic elastomer (TPE). This hood 170 also includes, for example, cells (not shown in the figures) formed within an internal volume defined by its walls. The implementation of such cells is well-established; those skilled in the art know, in particular, that they help limit heat exchange by convection since they contain air in a steady state.

[0093] The configuration and arrangement of the peripheral cover 170 described above are not exhaustive. Therefore, nothing precludes having a peripheral cover fixed to the opening frame 110 or to the glazing 130 in order to cooperate edge-to-edge with the peripheral extension 123 of the fixed frame 120.

[0094] It is also possible that the peripheral edge of the opening frame 110 may extend substantially beyond the peripheral edge of the glazing 130, for example so as to be aligned with the peripheral edge of the fixed frame 120. In this case, the peripheral extension is defined at the level of the external face of the opening frame 110, and the cover 170 cooperates edge to edge with this peripheral extension to extend normally to the glazing 130, for example up to the external face 132 of the glazing 130.

[0095] The alternative for implementing window 100 of figures 2a to 2cconcerns on the one hand the presence of the peripheral hood 170, and on the other hand also the configuration of the means of movement of the opening frame 110 in relation to the fixed frame 120. It being understood that these two aspects are independent of each other in the context of the realization of the window 100.

[0096] To that end, and as illustrated in the figures 2a to 2c , the external face 122 of the fixed frame 120 includes a peripheral groove 125 extending in the opposite direction to the glazing 130. Such a peripheral groove 125 thus forms a recess, for example rectangular in cross-section.

[0097] Furthermore, said intermediate piece 140 has, in cross-section, a substantially L-shaped form formed by a first arm 143 and a second arm 144. Said first arm 143 is configured to cooperate with said peripheral groove 125 during said translational movement normal to the glazing 130. Said second arm 144, for its part, supports sliding guides (not shown in the figures), for example configured identically to those described in the figures 1a to 1f Furthermore, said second branch 144 is configured to bear against the opening frame 110 during said translational movement normal to the glazing 130. For example, and as illustrated in the figure 2a, said second branch 144 is supported against the external face 122 of the fixed frame 120 when the window 100 is closed, at the level of a part of said external face 122 extending normally to the peripheral groove 125. Said second branch 144 also extends over a distance less than the width of said external face 122.

[0098] In other words, the intermediate piece 140 forms, in cross-section, a right angle configured to fit into the peripheral groove 125 of the fixed frame 120 when the window 100 is closed, and to push the opening frame 110 in translation during the first stage of the sliding movement. The second stage of said movement is carried out by means of the sliding guides.

[0099] According to this alternative design, the intermediate piece 140 is hidden when the window 100 is closed, which improves the overall aesthetics of the window 100. Indeed, the thickness of the multilayer structure is here approximately equal to the sum of the respective thicknesses of the glazing 130 and the opening frame 110 and fixed frame 120. This is due to the fact that the thickness of the second arm 144 is, for example, at most a few millimeters, typically 2 mm, and therefore negligible compared to those of the glazing 130 or the frames 110, 120.

[0100] It is noted that the movement of the intermediate L-shaped part 140 is achieved by means of hardware identical to that described in the figures 1a to 1f , for example by means of compasses fixed in the peripheral groove 125 between the fixed frame 120 and said first branch 143 of the L.

[0101] In another aspect, the invention relates to a pre-assembled unit, or kit, comprising profiles for assembling an opening frame 110, profiles for assembling a fixed frame 120, and means for moving them, so as to allow the construction of a window 100 according to the invention. The profiles are of the mullion and transom type and, for example, are delivered with a predetermined length. The lengths of the profiles are, for example, adjusted according to the opening in which the assembled window 100 is intended to be installed. Alternatively, the profiles in the kit have a standard length, so that they can be adjusted by cutting after receipt of the kit.

[0102] However, nothing excludes the possibility that the kit may include other elements, such as 130 glazing, 150 hardware for setting in motion means of movement, etc.

[0103] According to yet another aspect, the invention relates to a method for sealing an opening in a wall separating an external environment 20 from an internal environment 10. This method comprises the steps of: to obtain a kit according to the invention, to assemble a window 100 in the wall opening using said kit.

[0104] For example, window 100 is assembled before being installed in the wall opening. Alternatively, the window components are installed one after the other in the opening, for example, starting with the fixed frame 120.

[0105] In a particular implementation method, the window assembly step 100 in the wall opening is carried out so that the glazing 130 faces the external environment 20. This implementation method conforms to the description given above.

[0106] However, a different window position is not precluded. For example, in another implementation, the window assembly in the wall opening is carried out so that the glazing 130 faces the interior environment 10. In this way, when viewed from the interior environment in a direction normal to the glazing, only the glazing is visible. This implementation differs from the one where the glazing 130 faces the exterior environment 20 only in the window position 100, and therefore does not require any additional handling. It is thus understood that in this method, the external face of the glazing faces the interior environment.

[0107] The above description clearly illustrates that, through its various features and their advantages, the present invention achieves its intended objectives. In particular, it enables the creation of a window with excellent thermal and acoustic insulation performance, and easy design and assembly.
