EP0317425B1 - Window with dynamic insulation by air circulation, whereby the frame forms a box - Google Patents

Abstract

The invention relates to a frame for a glazed bay, each glazed element of which opens up like a box, into two glazed parts of similar size, enabling numerous elements traditionally placed on the outside (blinds, curtains, security equipment, heating etc.) to be incorporated into the hollow space between the two glass panels. This invention relates to windows having parietodynamic insulation by air circulation, having one or more ventilated air jets, which thus have a high degree of thermal insulation. These windows may have the two parts made from identical or different materials. These windows may be supplied with electricity, which enables electrical equipment to be incorporated. <IMAGE>

Description

The present invention relates to a carpentry in which each glazed element opens like a box, into two glazed parts of similar importance, making it possible to incorporate into the hollow space between the two glazings, numerous elements traditionally placed outside. In addition, this space between the two glazed parts is ventilated. This invention relates particularly to windows with parietodynamic insulation with one or more ventilated air spaces, that is to say with an air passage provided between the outside and the inside, passing around the glazing.

There are already traditional carpentries in which each glazed element opens like a box, in two glazed parts of similar importance, between which blinds or curtains can be placed. But in this case, when the two parts are closed against each other, the space is made as airtight as possible to have better static thermal insulation. In the case of the invention, on the contrary, there is an air passage between the interior and the exterior of the building through this free space created between the two glass walls.

There are already glazings, they are light frames surrounding a glazing, often mobile and removable on their supports linking them to the main and load-bearing joinery. They are most often placed on the inside of the window, but they can be placed outside. They are significantly smaller in section than that of the main carpentry. If the window corresponds to an opening part, only the main carpentry has hinges connecting with the frame, the glazing being carried by the main carpentry of the opening. There are already glazings placed either inside or outside, allowing parietodynamic insulation with a single air space. Insulations parietodynamics with two or more air knives are already covered by a patent from the same inventor.

Thus the glazing, blinds, curtains, roller shutters ..., are outside the main joinery because the solid and non-removable uprights do not allow them to be placed inside for traditional windows.

The documents WO-A-8701155, DE-A-3.148.345 and WO-A-8602692 describe windows comprising at least three glazings forming boxes.

Document WO-A-8602692 describes a window or French window with parietodynamic insulation by air circulation, comprising at least two ventilated air layers, therefore at least three glazing, the joinery opening in two important parts similar, the internal glazing (s) being blocked between the glazed parts.

The two glazed parts define a box delimiting a hollow space in which can be received at least one accessible accessory such as blinds, curtains, security, lighting, heating and ventilation systems.

• un ou plusieurs vitrage pour l'isolation pariétodynamique, c'est-à-dire lorsque la conception de la fenêtre permet le passage de l'air entre l'extérieur et l'intérieur en contournant chaque vitrage faisant chicane, réalisant ainsi un échangeur thermique par les vitrages.
• des stores contre le soleil à mouvement horizontal ou vertical.
• des rideaux
• des appareils de sécurité contre les chocs, les bris, les découpes sur les vitrages, ou sur toute la fenêtre ou porte-fenêtre,
• des éclairages,
• des appareils de chauffage,
• des appareils de ventilation,
• des appareils produisant des sons ou de la musique.

The object of the invention is to produce a window in which the glazed part, opening or fixed, is constituted by a joinery forming a box, opening in two important parts. similar, each being glazed. Thus it is possible to place between these two panes:

• one or more glazing for parietodynamic insulation, that is to say when the design of the window allows the passage of air between the exterior and the interior bypassing each glazing forming a baffle, thus achieving a heat exchanger by the glazing.
• sun blinds with horizontal or vertical movement.
• curtains
• safety devices against impact, breakage, cut-outs on glazing, or on the whole window or French window,
• lighting,
• heaters,
• ventilation devices,
• devices that produce sounds or music.

• soit être réalisées dans le même matériau (bois, pvc, aluminium acier, ...). Un intérêt supplémentaire provient du fait qu'il est possible de réaliser d'un seul coup la menuiserie, comme pour une fenêtre classique, puis celle-ci est sciée en deux dans l'épaisseur : d'où un grand gain de temps et l'assurance d'une parfaite adaptation dimensionnelle des deux parties de la boîte formant la menuiserie. Les finitions se font après séparément pour chaque partie de la menuiserie boîte.
• soit être réalisées par deux matériaux différents, tels que bois-aluminium, bois-pvc, acier-pvc, ... Chaque partie de la menuiserie boîte est donc réalisée dans un matériau différent, ce qui facilite la fabrication. Il est ainsi possible d'ajouter les qualités mécaniques, esthétiques et d'entretien de chaque matériau et d'améliorer ainsi les performances des fenêtres. Entre les deux parties, les joints peuvent, à la fois avoir une fonction de barrière thermique entre les deux matériaux, par exemple entre aluminium et bois, ou entre deux matériaux peu isolants thermiquement, par exemple aluminium-aluminium ou aluminium-acier, et avoir la fonction d'étanchéité à l'air pour des fenêtres à isolation pariétodynamique.

The two parts of the box can:

• either be made of the same material (wood, pvc, aluminum steel, ...). An additional interest comes from the fact that it is possible to realize at one time the joinery, as for a traditional window, then this is sawn in half in thickness: hence a great saving of time and l '' assurance of a perfect dimensional adaptation of the two parts of the box forming the joinery. The finishes are done afterwards separately for each part of the box joinery.
• either be made by two different materials, such as wood-aluminum, wood-pvc, steel-pvc, ... Each part of the box joinery is therefore made of a different material, which facilitates manufacturing. It is thus possible to add the mechanical, aesthetic and maintenance qualities of each material and thus improve the performance of the windows. Between the two parts, the joints can, both have a thermal barrier function between the two materials, for example between aluminum and wood, or between two materials which are not very thermally insulating, for example aluminum-aluminum or aluminum-steel, and have the air tightness function for windows with parietodynamic insulation.

The two parts of the box joinery are held mechanically on one side by a movable connection, for example by hinges, on the other by a blocking assembly, for example visible screws on the front of the window or hidden locking elements on the edge of the window or the French window.

In an opening, half of the supporting box-joinery and connected for example by hinges to the frame can be the outer half or the inner half, both cases are possible.

In a fixed part, half of the joinery-box can be outside but more often inside.

In this hollow space between the two glass parts of the window-box, all filling combinations are possible: one, two, three, ... n glass or transparent walls produced by synthetic products (plastic, ...) . The spaces occupied by blinds, curtains, security devices, lighting, heating devices, ventilation devices, devices producing sounds, can be placed either near the exterior glass, or near the interior glass, or in the center; these spaces can be ventilated or not.

If there is a need for a lot of free space between the two glazed parts of the window-box, it is possible to have hollow frames serving, like table extensions, to enlarge the hollow space. They have the same external dimensions as the glazed parts. They are connected to the glazed parts like the glazed parts to each other, when there are no hollow frames. Most generally there would be at most a hollow frame.

One of the advantages of these incorporations with a window with parietodynamic insulation comes from the fact that, thanks to this there is a very good thermal insulation and there is no condensation between the glazings, or little risk of corrosion and less soiling. In addition, there is no excess temperature as soon as there is sun, solar energy being driven by the air, hence greater security in terms of expansion and for electronic devices. Window components can thus become very industrially manufactured elements in the factory, incorporating many sophisticated devices, fitted with precision and at low cost in the factory. The installation on the site will hardly be increased compared to that of a conventional window, but the connection The electric window can allow much wider and more complex uses than those offered by a traditional window.

In Figure 1, the opening of the window-box shown schematically in principle comprises the outer glazed part (1) and the inner glazed part (2) of similar importance, with a hollow space (3) between these two parts . The separation (4) between these two glazed parts is substantially mid-thickness of the joinery, it may contain a seal which can also serve as a thermal barrier. In the drawing, the interior glazed part (2) is load-bearing, the glazed part (1) is carried by the glazed part (2) thanks to the hinges (5), and blocked closed either by the screws (6) or by lateral locking. (7). The air passes from the outside to the inside through passages (8) placed in the solid parts in such a way that this ventilation uniformly scans the entire hollow space providing the parietodynamic insulation of the window.

In FIG. 2, the third window (9) is blocked between the two glazed parts (1) and (2) of the opening of the window-box according to the invention. The partition (4) is made airtight by joints made by the glued joinery (4a) supporting the third window and below by a baffle (4b). The outside air enters through the passage (8a) corresponding either to a mouth (8a1), or to a passage through the frame and the opening (8a2). The air exits through the passage (8b) corresponding either to a notch in the opening (8b1), or to a mouth (8b2). The opening is made in one go, then sawn in half, making the two glass parts (1) and (2). Thus, a parietodynamic window with two ventilated air spaces is produced.
