Description

• ♦ • ♦

The invention relates to a glass element, in particular a window or a door, with profile elements, in particular made of plastic, and with at least one surface element comprising at least two panes, in particular of glass, each with an inner surface and an outer surface, wherein the inner surfaces facing each other, and the discs by at least one spacer to form a Zwi · .. · # «· ·

and an outer periphery on which the profiled elements are arranged and a method for producing the glass element after the discs with the spacer therebetween via an adhesive, in particular an elastomer, such as. a butyl rubber, are joined to the surface element.

Laminated glass windows are usually manufactured in two independent steps. In a first step, the laminated glass is manufactured by the glass manufacturer. For this purpose, at least two glass sheets are connected via a spacer. The space thus formed is filled with Isolierglasfenstem with a noble gas. In order to ensure the tightness, a so-called edge bond must be made on the circumference of the laminated glass. This finished semi-finished product is then transported to the window manufacturer, who then uses this in the Glaseinstand of profiles and connects with these via another adhesive with the profiles. This is associated with high logistical and production engineering effort and costly. In addition, attention must always be paid to the material compatibility, in particular with regard to the plasticizers contained, of the various adhesives used for producing the edge bond or for incorporation into the profiles, as a result of which the usable materials are unnecessarily limited to a small number. N2004 / 16000

In order to avoid this problem, it has already been proposed in the prior art that window production as a whole be performed in one step, i. without making the detour via the semi-finished product. Such a method is e.g. known from US 6,055,783 A. The glass panes are placed directly in the sash without first having to make an insulating glass unit separately. The support of the window structure takes place without the use of a spacer, i. the support of the individual panes is an integral part of the casement. Surprisingly, however, it has been shown that this type of window production does not provide the desired savings of a financial nature and in terms of workload. This is primarily due to the fact that instead of a glass element now has to be handled with several individual glass elements and that the conversion of production lines is possible only with great effort.

It is the object of the present invention to provide a method by which the window manufacturing can be carried out more economically.

This object of the invention is achieved in each case independently by a glass element and a method for its production of the type mentioned, in which the spacer of the glass element with at least one surface of the profile elements via a single layer of a bonding agent to form a marginal composite is non-positively connected or becomes

In the case of the production method according to the invention, therefore, the surface element, in particular the insulating glass, is glued to the profile elements in a production step and at the same time the edge bond is produced. Thus eliminates the previously customary production of the edge bond in advance and can thus be dispensed with this one layer, since the function of the edge bond, namely the guarantee of tightness, is taken over by the bonding agent. For the window producer this means primarily a simplification in the logistical process and thus a cost saving. Furthermore, the proportion decreases to fractional disk units, since the disks must be arranged less. Mixing and bringing the bonding agent, so the bonding agent needs to be done in this type of production only for one operation.

In addition, material saved and no longer needs to be paid to a special material compatibility in terms of the interaction of edge seal and bonding.

Adhesive for connecting the spacer can be minimized or excluded.

It may further be provided that the adhesive is self-sealing, i. that after piercing the adhesive layer, e.g. to introduce a gas filling, the puncture hole automatically closes again when removing the filling lance, so that the escape of gas from the space between the panes can thus be largely avoided and can be dispensed with additional measures to close the hole. As filling of the intermediate space, the gases or gas mixtures usually used in the production of insulating glass are used.

According to a development of the invention, it is provided that the adhesive is selected from a group comprising silicones, polyurethanes, polymers, hybrid adhesives. These adhesives have the desired properties in order to achieve a durable and largely shear-resistant connection between the components of the insulating glass unit and the profile arrangement.

It is also possible to non-positively connect at least one further disk with surfaces of the profiles, wherein the surface element according to a further Ausfuhrungsvari- N2004 / 16000

Ante this may include at least one other disc. As a result, three-bar windows can be produced more economically.

The at least one further disk can be larger or smaller than the two other disks to form a stepped glass. The resulting step glass or frameless window or the frameless door opens up more applications and advantages in terms of sound and / or thermal insulation, especially for use in commercial property, but increasingly also for private applications. It is thus also possible in the space between single and double glazing other elements, such as. Venetian blinds, roller blinds or insect screens, to be protected from external environmental influences. It is also possible that the spacer is arranged at a distance from the outer periphery of the discs. In the resulting intermediate space of the adhesive can be arranged with a greater layer thickness, whereby the edge bond can be given a higher mechanical strength and the tightness of the edge bond can be further improved.

The adhesive may be disposed between the discs. It is also possible for the adhesive to extend at least partially into the area of at least one end face of at least one pane. According to one embodiment of the invention, it is further provided that the adhesive extends into at least one of the outer surfaces. The window profile can thus already be adapted to different requirements during production.

In order to improve the connection between the profile element and the bond, at least one extension may be arranged on the profile element, in particular integrally formed therewith, which may be in the region of the gap, in particular in the region of the adhesive. According to the variant, the extension can be made of a group comprising plastic, metal, glass, ceramic. If, as in a training provided the extension hook-shaped, helical, C-shaped, G-shaped, the compound by the enlarged surface to which the adhesive can adhere, and a "hooking" in the adhesive, further reinforced and thus the glass - N2004 / 16000 ♦ ··· ···· • · • · ♦ ··· ······································································· • · · · · · · · · · »·

element be made even more durable or the construction will be given a greater stability.

According to a development of the method, it is provided that the surface element is at least partially spaced from the surfaces of the profile elements, optionally via a glass edge, inserted into a groove of the profile elements, and the gap between the surface element and the surfaces of the profile elements is filled with the bonding agent. It can thus be produced a sufficient layer thickness of the adhesion promoter, so that it has a sufficient capacity to compensate for thermal stresses. Furthermore, it is possible that the bonding agent is injected or pressed into the space so that it is filled as completely as possible with the bonding agent, and thus a greater tightness can be achieved. In addition, the feeding of the primer under pressure can reduce the processing time, and it is also possible to form the feed opening for the primer with the smallest possible cross-section. In addition, even more complex cross-sections of profile elements can be processed by this process variant with high reliability of the filling of the bonding agent. ·········

It is advantageous if the injection of the bonding agent in the gap with a lance, which is guided through an opening in the profile elements, takes place, since thus the degree of automation of the production of windows or doors can be further increased.

It is possible that the bonding agent is introduced from the side into the intermediate space, so that can be dispensed with complex machine devices for introducing the lance in a well-positioned opening in the profile element.

According to a development, it is provided that a prepolymer is used as the adhesion promoter, which is polymerized ready after the entries in the gap. This makes it possible for the filling process to use a bonding agent with lower viscosity, whereby the filling itself can be simplified. N2004 / 16000

> 53 [ϊ ··· ♦ ·

It can further be provided that after the frictional connection of the surface element with the profile elements, a gas, in particular a noble gas, is introduced into the space between the panes, thus improving the thermal insulation of the glass element. By introducing after the non-positive connection, the handling of the surface element is facilitated in advance. It is also possible that the introduction of the gas through an opening on an end face or a narrow side of a profile element, in particular at the point of use of the edge composite or through the edge composite, takes place, wherein optionally the same opening as for the supply of the primer can be used. Since these locations are normally not visible in the installation position of the glass element, no special precautions need to be taken with regard to the coverage of this opening (s) with regard to the optics of the glass element.

The introduction of the gas can take place by means of an introduction device, in particular a nozzle or a lance, whereby variations of the nozzle thickness or the nozzle tip can be used to address different adhesives, processing temperatures, processing sites, etc.

Depending on the degree of production or future requirement for the glass element, it is finally possible that the extension is formed during or after the generation of the profile element. A coextrusion of the extension in the course of profile production is just as possible as an individual attachment of individual hooks or a hook strip in the completion of the glass element. If the adhesive for the subsequent compound of the invention in the profile element production is not yet selected, the respective quality requirements can be met by a just-in-time attachment of the extension.

The time savings that can be achieved with the method according to the invention, especially for orders under deadline (by clients, replacement of broken windows or doors, weather, renovation, other trades, penalties, etc.) bring decisive benefits.

For a better understanding, the invention will be explained in more detail with reference to the following figures.

Each shows in a highly schematically simplified representation:

1 shows a part of a cross section of a glass element according to the invention;

2 shows a variant of the glass element with an alternative bond;

3 shows a glass element with 3 panes;

Fig. 4 shows a further Verklebungsvariante the glass element.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and to transmit mutatis mutandis to the new situation in a change in position. Furthermore, individual features or combinations of features from the various exemplary embodiments shown and described can also represent separate, inventive or inventive solutions.

1 shows a glass element 1 according to the invention. The main component is a first disk 2 having a first outer circumference 3, a first outer surface 4 and a first inner surface 5 and a second disk 6 with a second outer circumference 7 arranged at least approximately parallel thereto a second outer surface 8 and a second inner surface 9. The inner surfaces 5, 9 face each other. Between the disks 2.6, preferably at a distance from the outer circumference 3, 7, there is a spacer 10, which is held with an adhesive 11 arranged between the disks 2.6. The material of the adhesive 11 is usually a butyl elastomer, e.g. Butyl rubber. The two disks 2.6 are preferably made of glass, but may also be made of another material, e.g. consist of a plastic. N2004 / 16000

The disks 2, 6 together with the spacer 10 form a surface element 12.

In glass elements 1 according to the prior art usually below the adhesive 11 is normally a DichtstofF, such as polysulfide or polyurethane, immediately downstream. The non-UV resistant polysulfide is replaced by a silicone sealant in free glass edge designs. This known from the prior art edge compound, consisting of the spacer 10 and the sealants serves as a water vapor and gas diffusion barrier, connects the discs 2, 6 and closes the unit hermetically sealed.

Another edge bond is located circumferentially over the entire circumference of the surface element 12. This creates an intermediate space which is filled with gases, in particular noble gases, gas mixtures, gas-air mixtures or air. The entire glazing unit forms an insulating glass known from DIN 1259 Part 2 and from EN 1279 Part 1.

This insulating glass is subsequently connected to the latter with another adhesive which is placed between the sealing material and the window profiles.

In contrast to this, according to the invention, this further adhesive is dispensed with, and the surface element 11 consisting of the disks 2, 6 and the spacer 10 arranged therebetween is inserted directly into a glass fold of the glass element 1, i. a profile element 13 is inserted and connected to an adhesion promoter, for example an adhesive 14, with at least one surface of the profile element 13, i. that at least the spacer 10 is connected directly to the surface of the profile element 13 directly via only a single layer 15 of the adhesion promoter.

The adhesive 14 is preferably selected from a group comprising silicones, polyurethanes, polymers, hybrid adhesives. A Butylkautschukverträglichkeit is advantageous in terms of the attachment of the spacer 10 to the discs 2, 6. The adhesive 14 may be self-sealing to prevent diffusion of gases, gas components, water vapor, etc. in the event of damage to the layer 15, for example after a puncture, e.g. to bring a rare gas filling in the space between the discs 2, 6, largely hinan to keep.

To produce the frictional connection, the adhesive 14 can be introduced into the glass element 1 by means of a feed device 16, which can be made out as a nozzle, lance, pipe, injection system, cannula, etc. This introduction can take place under pressure, without pressure, by gravity, by injection, filling in, pressing in or in any other suitable manner. The adhesive 14 can be introduced into a gap 17 which is formed between the surface element 12 and a profile element 13 by the spaced arrangement of the surface element 12 in the profile element 13. The spaced-apart support can be made, for example, by means of at least one glass edge 18, which may be formed on the profile element 13. It is thus a permanent connection with the discs 2.6, the spacer 10 and the profile elements 13 generated. The introduction device 15 can at least partially penetrate at least one profile element 13, for example, be guided from below through the profile element 13, as shown in Fig. 1.

The profile element (s) 13 may be formed according to the state of the art in the window production. For example, they can be made of plastic, metal or wood. In particular, the formation of hollow chamber profiles is possible, which also with a metal stiffening, e.g. made of steel and may optionally be at least partially filled with foam. Such embodiments are already known from the prior art, and therefore the skilled person is referred to the relevant literature at this point.

The glazing rebate is usually formed as a circumferential groove of several, in particular interconnected, profile elements 13. But it is also possible that this incidence is formed only by a gradation in the profile elements 13, these steps are optionally covered after insertion of the surface element 12 with a cover.

The control of the introduction device 16 or the amount of the adhesive 14 introduced can be effected via a data processing system, such as e.g. a PC, done.

From the controller, it is possible to use an adhesive composed of one or more components 14 or a corresponding adhesion promoter, wherein the choice of the adhesive 14 or the mixing ratio of the components from N2004 / 16000

·· '. \ · · - m * ·

may be dependent on the future application of the glass element 1 produced, e.g. in a passive house, as avalanche protection window, as all-glass construction, in the very wind-exposed area, for (single-pane) safety glass (ESG) etc.

FIG. 2 shows a variant of the glass element 1 with an alternative adhesive bond, wherein the adhesive 14 extends into a region of end faces 19, 20 of the disks 2.6. It is also conceivable that the bonding only extends into the area of at least one pane 2, 6 or its end face 19, 20. This type of bonding, which at least partially includes the end faces of the discs 2, 6, is more resistant to stresses, in particular stresses, wind pressure, etc., and can be used inter alia for large-sized discs.

The bonding or the connection with the profile element 13 can be used in all-glass structures, that is, for example, with a so-called stepped glass with a further disk 21 (FIG. 3), since the joints are well or nearly "invisible" in the frame construction.

In Fig. 3, the further disc 21 is shown, which is larger than the discs 2.6, and which can partially or completely cover the window frame and thus protect. Advantages of this construction include, among other things, easy maintenance of the windows, a reduced number of or no maintenance joints and no need to paint. The step glass can be glued to a subframe and mounted on the door or window frame. In order not to get an insight into the holder and the frame in the area of the gluing, the glass edge can be provided in a corresponding width, e.g. enamelled, tinted or laminated.

It is possible, if such a gluing variant for all-glass inserts in the claimed area such as object facades, large-format glazing, etc. is to be used, at the respective edge of a disc lamination such. to apply a sandblast, an etching, a grinding, a partial or total frosted glass effect, which at least partially obscures the bond, but gives the impression of a largely closed and / or uniform glass facade or glass surface and thereby hardly or hardly applies. N2004 / 16000

· * ·

Similarly, of course, a smaller disc 21 is conceivable, for example, in the listed area, in Altbausanierungen etc. on the façade side by a smaller externally visible window surface or by wider wing and / or frame to give the impression of smaller windows.

In all the embodiments of the invention, since the introduction device 16 either remains in the glass element (1) after the introduction of the adhesive 14, and e.g. With a closure, in particular a plug, a seal, a shell, a plug, a pouring means, a sealant, etc. closed and / or sealed or can be removed after the production process, it is here dashed lines shown.

From Fig. 4 it can be seen that the adhesive 14 extends into at least one of the outer surfaces 4, 8. Those disks 2, 6, which are thus at least partially enclosed by the adhesive 14 in their peripheral areas, have an even higher resistance to mechanical influences than the disks 2, 6 described in FIG. 2.

In the region of the adhesive 14 are two extensions 22, which serve primarily as an interlocking or Hinterhakung for optimum connection between the profile element 13 and the adhesive 14. Similar to the glass edge 18, the extensions 22 can be attached separately to the profile element 13. Exactly so it is possible that the extensions 22 are already mitextrudiert in the course of the preparation of the profile element 13 so that the component has an improved adhesion to the adhesive 14.

The extension 22 or the extensions 22 can / can not only be located horizontally as shown, but also vertically on the profile element 13.

The forestry set 22 may be formed as a single element, or it is possible to arrange a plurality of projections 22 on a separate or integrated extension strip, or this extension strip may be continuously formed as a profile, so that it no longer has individual projections 22. N2004 / 16000 ···· ···· • · • · · · ·

In the context of the invention, only one extension 22 or an extension strip can be arranged, or it is possible - viewed in cross section - more than two of these extensions 22 and extension strips to be arranged side by side.

By adjusting the amount of adhesive 14, the thickness of the gap 17, the design of the profile element (s) 13 or 13 further modifications in the window structure, in particular in the resistance to thermal and mechanical stresses are possible.

Although the description is directed only to windows or doors, it is possible to apply the invention also to other glass elements 1 with partially different to glass surface elements 12.

The embodiments show possible embodiments of the profile arrangement, which should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching of technical action by representational Invention in the skill of those skilled in this technical field. There are therefore also all possible embodiments, which are possible by combinations of individual details of the illustrated and described embodiment, the scope of protection.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the profile arrangement, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.

The problem underlying the independent inventive solutions can be taken from the description.

Above all, the individual in Figs. 1; 2, 3, 4 form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures. N2004 / 16000 • · ···
