Description

ELEMENT WITH AN INSULATING GLASS BOMBEE

An insulating glazing unit having a curved pane, which presents the features of the preamble of claim 1.

By insulating glazing unit as defined in the present specification, is meant a flat element formed by at least two rigid panes and a spacer frame connecting these two panes to each other. The spacer frame is assembled to the inner faces of the panes with thin adhesive layers. The two main faces facing each other of the rigid panes and spacer frame define a gap between the panes, which is generally closed in sealed manner to the air and moisture. By "rigid", we refer here to the relative rigidity of glass panes and plastics as compared to softer materials.

For purposes of the invention described herein, it is considered of the rigid panes of glass and plastic, and this as well in monolithic form in composite form (at least two rigid panes assembled to each other by gluing surface with a layer or an adhesive sheet). In addition, one can use both prestressed glass panes, partially prestressed or not prestressed.

EP 0921260 Bl discloses such an insulating glazing with a stiff flat pane and a rigid curved glass cylindrical form. Around the relatively strong curvature, the hollow profile spacer frame form of this glazing panel is provided with a projecting rib, which must fill the slot crescent-shaped hollow profile between the straight and the curved glass . Such a special construction of the spacer frame is relatively complicated and therefore expensive.

From EP 1,657,396 A2 is known an insulating glazing unit with a curved pane of cylindrical shape, the spacer frame consists of a solid profile section, for example glass in the bending region supra.

The spacer frames in the hollow section are mostly filled with a drying agent, which extracts the gap between the panes, to some extent, any residual moisture and any moisture subsequently penetrating. In this manner, permanently prevents fogging on the inside of the windows, as long as it does not occur external damage (e.g. breakage of the glass, detachment of the bond between the spacer frame and windows).

Similarly, DE 203 04 806 Ul discloses inter alia insulating glazing units with rigid panes curved cylindrically, in which the two windows may have different radii of curvature. The document is however silent on the implementation of the spacing frame in this curvature region.

It is widely known to manufacture spacer frames for insulating glazing elements of elastomeric material, optionally thermoplastic, extrudable. This mainly aims to minimize the transfer of heat by heat conduction in the edge region of the insulating glass (insulating glass "warm edge"). These elastomeric spacing frameworks is still impose other measures, so that their sealing against the diffusion of water vapor can bear comparison with the values ​​of metal spacer frames. The only elastomeric material is not enough. Therefore, most executives of elastomers gap still include additional metal mserts are metallized on the outside or are provided with a thin film. It is also known to mix these materials with drying agents against humidity in the space between the panes.

EP 0875654 Al discloses a spacer frame hollow profile of elastomeric material, whose mechanical strength is enhanced by the incorporation of glass fibers.

EP 1195497 A2 discloses the manufacture of an insulating glazing unit with a frame of elastomer spacer and still plastically deformable after deposition (extrusion) on one of the rigid panes. So that air displaced during the laying of the second pane by compressing the spacer frame can escape without the first one must provide an opening in the spacer frame, the spacing frame is first, according to this description, compressed on one side more heavily than is actually necessary, so that the window is not yet placed on the opposite side. Then the glass is placed on the opposite side of the spacer frame, and the latter is compressed to its nominal thickness. In this case and until immediately before the closure of the last slot, the still trapped air is moved several times. In a last step, the first of more highly compressed side of the frame spacing is extended to its "nominal thickness". The document does not concern the production of curved glass in such an element of insulating glass.

By DE 30 02 904 Al as well as under the trade name "Swiggle Strip", an elastomeric material further is known with a flexible metal insert, for example of spacer frames for insulating glazing units. This material is also suitable, according to information provided by the website http: //www.bentglassdesign. com / Glasstypes .html (state in January 2007) for the assembly of two rigid panes curved in the same direction in an insulating glazing unit. In the domed glazed element shown here, the distance between the panes is equal everywhere, even in the curved regions.

The problem underlying the invention is to provide another insulating glazing unit comprising at least one curved pane and a frame spacing d 1 which has a variable cross-section, considered along its longitudinal extent, in the bending region of the glass.

This problem is solved according to the invention by the features of claim 1. The features of the subclaims present advantageous embodiments of this invention.

Accordingly insulating glazing units known having rigid curved glass, the curvature of the spacer frame is obtained according to the invention the plastic deformation of the material of the spacer frame imposed during the pressing of the bent glass. Note the in the finished product because the spacer frame has local extra thickness due to the material moves, which are naturally thicker in the region of the greatest deformation in the region of the largest arc length. Outside the gap between the windows, additional thicknesses may optionally be removed / eliminated. Regardless of this, they can be masked in a known manner by placing an external or secondary seal (polysulfide finishing). The material described in DE 30 02 904 Al is well suited for this application case of the invention, possibly after some modifications that will further described below. Of course, other similar materials may also be used to offset the curvature differences, since they have the necessary plastic deformability. It should absolutely not be in this document of a thermoplastic material, which must first be heated to the deformation or which can be deformed as the still hot after installation. Plastically deformable materials sustainably at room temperature are in principle also, in so far as they have the resistance values ​​required for the composite insulator and a sufficient adhesion to the faces of the rigid panes.

Although the case of preferred application is the combination of a curved pane and a flat pane, two different curvature windows may, however, also according to the invention, be connected to one another using the capacity compensation of the elastomer spacer frame in the region of different curvatures.

Naturally, the invention can be applied not only with glass curved in a cylindrical form, but also with curved glass in the space until their edges, in which there are therefore more than two curved lateral edges to be assembled with the spacer frame. In this case, the deformability is used the spacing frame material at each curved edge, to which it is necessary to compensate for different bends or different curvatures between the pairs of windows.

During the implementation of the present invention, it may be useful to use different base heights for the spacer frame on the edges without curvature and the edges of the bending region, that is, say to achieve this for example with a total of four segments (two different pairs of segments). In the bend region, use a form of wider achievement with the required compression volume in the region without bending the profile can be narrower. This has the advantage that it does not compress the material so strongly on the longitudinal edges. It could also be performed and greater arc heights.

The disadvantage of this embodiment is, however, that is each corner a welding point or junction, which must also be sealed.

In such an embodiment, it would also be possible to manufacture the segments of the spacer frame, in which no curvature is required, in a conventional material to the conventional metal spacer frames. One could even imagine to manufacture all the spacer frame in conventional metal profiles and to provide them in the bending region of a layer of plastically deformable material and able to compensate for the curvature. It is not intended by the compensating small irregularities of a pane (which is naturally also possible to a small extent with the normal adhesive materials between the spacer frame and the glass surface), but exclusively a curvature difference compensation with heights arc of several millimeters.

Furthermore, one can implement the invention, according to the curvature of height, with prebent panes or also flat glass panes, whose curvature is imposed that during compression of the spacer frame, in the frame their elastic deformability. Such "cold-bending" can be retained in the finished product using the strong adhesion of the spacer frame, in so far as the distance d 1 frame material has a dimensional stability and creep resistance sufficient long term.

Finally, electrical and / or electronic functional elements may, in known manner, be incorporated or integrated into such an element of insulating glass. These can be found both in the gap between the panes as within a laminated pane used as rigid pane, if you can not or if you do not want to install a outer faces. It is conceivable here, for example, functional elements such as electrochromic or electroluminescent displays, lamps, displays, solar cells, sensors and indicators, heating elements and / or antennas. Similarly, non-electrical elements, such as thermochromic or photochromic surface elements such as naturally transparent coatings and / or opaque, particularly thermal barriers and / or light filters and / or color, may be combined with insulating glazing elements according to the invention.

insulating glazing elements of the type described here are suitable for the most diverse uses, both in vehicles and in buildings. For example, these insulating glazing units can be used for the glazing of vehicles - for example in bus - and preferably in the lateral glazed roof passage region. The curved glass is then placed on the outside and is adapted to the outer contour. The inner flat glass or curved differently can then be provided with additional functional elements, for example surface lamps or other additional equipment.

Further details and advantages of the object of the invention appear from the drawings of an exemplary embodiment and by its detailed description which follows.

In these drawings, which are schematic no particular scale,

Fig. 1 is a view of an insulating glazing unit performs according to the invention; Fig. 2 is a sectional view of the same along insulating glazing unit of the section II-II line shown in Figure 1;

Fig. 3 shows two views of part of the segments for spacing the insulating glazing unit according to Figures 1 and 2;

Fig. 4 is an exploded representation of an insulating glazing unit according to the invention before installation of the rigid curved pane on the spacer frame prepared.

In Figure 1, there is shown a plan view of an insulating glazing element 1 comprising an upper rigid curved pane 2 and a rigid pane plane underlying 3. In the embodiment discussed here, it exceeds a few centimeters the contour of the curved pane 2 so as to form a stepped insulating glass element.

Below the top glass 2, there is indicated the outline of a spacer frame 4, which extends peripherally along the entire perimeter of the insulating glazing element 1 and which delimits, with the main inner surfaces of two rigid panes 2 and 3, a gap between the panes sealed in air and 1 moisture. Reference numeral 5 denotes the inner edge of a colored layer by opaque nature, which is filed in frame shape on the inner face of one or both rigid panes 2/3 and which surrounds the actual field of view of the insulating glazing unit also transparent. This colored layer serves on the one hand - in known manner - to visually hide the spacer frame elastomer 4 and its links bonded to the two rigid panes, on the other hand to protect the elastomer material and the layers or beads of adhesive against UV radiation and against embrittlement / loss of adhesion resulting in the long term.

The opaque colored layer is not opaque in the representation, for reasons of the frame spacing of visibility. It can moreover also extend beyond the projection of a side edge of the window 3.

The curvature of the pane 2 is not visible in the

1, because it raised in the opposite direction to look, therefore out of the plane of the drawing.

A look at the section along the line II-II of Figure 1, shown in Figure 2 illustrates the shape and configuration of the spacer frame 4 in the bending region. In the remainder of the perimeter of the glazing unit, or the edges of the panes are mutually parallel (longitudinal edges), the spacer frame is simply straight and has a constant cross section. As already mentioned, there may also be achieved with frame segments in conventional metal profile.

It is emphasized that the arc height above the rope in the curvature region (here along the short side edges of the insulating glass element) may be in the range of a few millimeters (between> 0 to about 6 mm) as a function of the length of the rope. As an example may be mentioned a radius of curvature of about 2000 mm for a line about 300 mm with a glass thickness of 4 mm. This results in a maximum arc height above the chord of about 5.5 mm.

In Figure 2, first it is further seen that the spacing frame 4 is reinforced by a non-visible 4M metal insert in Figure 1. This 4M insert has a constant cross section. The raw material for the spacer frame 4 is made endless as an extruded profile (for example coextruded) and cut to the required length. In this case, it is not particularly difficult to seal adequately the welding points between profile portions, because the material is very deformable plastically, and also has good adhesion to the usual filler materials, sealing and gluing.

Anyway, the corner regions, which are found in this representation of the two sides of the visible segment spacing frame 4 can be produced without difficulty by bending the material. As seen by comparison with Figure 1, the rectilinear frame segments of the longitudinal sides of the insulating glazing unit, wherein the cross section is fixed, are connected to these corner areas.

One can also see in Figure 2 that the spacer frame 4 is slightly recessed inwardly peripherally with respect to the outer edges of the two panes 2 and 3. In the circumferential groove that remains is placed so known per se, after completion of the bond between the spacer frame and the rigid panes, a secondary seal polysulfide, not shown, which preferably fills the groove fully.

Finally, it is seen that in the embodiment illustrated here, one metal insert 4M is slightly off-center relative to the longitudinal extension of the spacing frame 4.

In Figure 3, this is shown to a slightly larger scale by means of an elevation view and a cross-section bent to the right. This measure is certainly not absolutely necessary for manufacturing an insulating glazing unit according to the invention, but it can also work with conventional profiles symmetrical in so far as there is sufficient displaceably next to elastomeric material the insert.

The basic embodiment of the spacer frame is known from DE 30 02 904 Al mentioned in the introduction. Here there is provided a further variant, in that one metal insert 4M is open towards one side or, in other words, is embedded in the elastomeric material in an open channel on one side. In the mounted state, the opening of the channel is located outside, thus the opposite of the gap between the panes, and it is not visible to the observer.

On the side facing the gap between the panes, the spacer frame has a closed unitary image.

The compression of the spacer frame 4 from the initial state (shown for example in Figure 3) and the deformed state between the curved pane 2 and the plane glass 3 with a variable cross-section in the longitudinal direction (indicated in Figure 3 by a curved line interrupted with a strong shortening in perspective the possible arc) occurs in the direction of the transverse extension of one metal insert 4M flat by nature, but slightly corrugated to facilitate deformation (bending) . Therefore, its width must be everywhere less than the minimum distance between the two rigid panes 2/3, so that the metal does not come into contact with the faces of the panes.

The unilateral opening of the channel formed in the elastomeric material of the spacer frame to one metal insert 4M facilitates the movement of the elastomeric material necessary for the variation of the cross section. It flows the compressed state on the one hand to the side (the spacer frame it becomes slightly thicker), it can however also be moved in the first open channel and fill the latter partially or fully. If necessary, either one will deform the elastomeric material of the spacer frame still in the hot state after hot deposition or be heated for the said deformation operation, to the extent that it is not sufficiently plastically deformable at temperatures conventional implementation (room temperature).

Figure 4 is an exploded view showing, by way of example, in the form of Evide drawing, the various parts necessary to the composition of an insulating glazing unit 1 according to the invention before installation of the curved pane 2. This -ci has its convex basic shape (curved) already prior to installation. It is also provided with a colored layer frame, opaque in reality but indicated only by its inner edge 5, as shown in Figure 1. On the flat glass 3 there is disposed along its outer edges and with a light back towards the inside, four segments of a spacer profile, in each case two segments 4.1 and 4.2. It is clear that the segments 4.2, which will be adapted to the curved edges of the pane 2 are higher than the 4.1 segments along the straight longitudinal edges of the insulating glass element 1. It has trace in the 4.2 line segments 4A in dashed lines, which reproduces the arc of the edges of the curved glass, and thus also the outline that these segments are 4.2 after laying and pressing the curved pane.

Can be achieved in different ways the state of deformation of the curved pane 2 shown in Figure 2 and indicated in Figure 4. In general, we put a previously curved pane 2 in cylindrical form on the spacer frame already filed on the flat glass 3, and by pressing one approach, optionally in several steps, the edges (lengthwise) to the flat glass 3, until the highest region of the arc of the curvature of the window pane 2 is also securely adhesively bonded to the spacer frame 4. in this region of the top as well, so it will cause safety by at least a slight compressive deformation of the elastomeric material. A previously curved pane 2 is not necessarily still further deformed during this operation, except possibly in the region of elastic deformation, a surface supporting the stationary arc it being possible here as necessary to avoid breakage.

the curved pane 2 cold however can also deform within its elastic deformability range, for a similar pressing operation from an initially flat shape, when the material of the glass is not too thick. With such an original shape, if one only loads edges (longitudinal), it necessarily establish a curvature of the glass due to the reaction of the spacer frame 4 to be deformed. a defined measurement of the arc height may also be achieved by a central support in the bending region

(Effective between the inner sides of two rigid panes in the region of the peripheral outer groove) or alternatively by a bending jig temporarily placed between the two rigid panes parallel to the spacer frame is deformed.

Of course, it is also conceivable combinations of the two methods. For example, it can bring its final resiliently curved shape during the pressing operation, an initially slightly pre-bent glass. This has the advantage that the restoring forces acting on the spacer frame glue are not as high as for a glass cold goes from the planar state.

After curing, bonding, etc., glues final assemblies between the spacer frame and the rigid panes, and also the elastomeric material after the solidification itself, the elastically curved pane will retain the desired shape without it being should take other measures. Such an approach is also known per se for laminated glass curved.
