DE19701386A1 - Frameless door or window sash arrangement with double glazing - Google Patents

Description

The invention relates to a frameless door or window sash arrangement Insulating glazing according to the preamble of claim 1, according to Main patent. . (Patent application 196 28 034.6) and / or (first) additional patent. . . (Patent application 196 54 748.2).

Conventional door and window sash arrangements essentially consist of one Door or window frame in which a pane arrangement is inserted. Of the Window frames now also carries the fittings by means of which the arrangement in one conventional frame (door frame or window frame) can be used and this is arranged opposite pivotable and lockable. In particular, too so-called turn / tilt fittings known, by means of which the window or Door leaf arrangement can be pivoted or tilted relative to the frame, depending on the position of an operating handle, wherein in a third position Actuating handle achieved a firm locking in the frame by means of the fitting being tight to the outside by using circumferential seals is reached. So-called insulating glazing is also conventional used. Insulating glazing is a pane arrangement of at least two spaced glass panes, with a so-called Spacer is glued in a gas-tight manner, with an edge filling, in general a thiocol mass, a further seal to the outside is achieved. The spacer mostly contains a moisture absorbing material to keep moisture out of the tight closed space between the two panes and the Absorb spacers. This space between the panes can be evacuated, it can however, it may also be filled with certain gas mixtures. The glass surfaces can with Thermal protection, sound insulation and / or radiation protection coatings may be provided.  

In door arrangements such as those found in sports facilities (so-called squash courts) are known, single-pane glazing without a frame has already been used. The The fittings required for the rotating movement of the glazing are clamped in or screwed over holes. If rails are attached on the edge, there are also tilting beds Impact orders possible, but again frame-like character is given.

There is now a desire, at least for design reasons, to also include frameless door and to provide window sash assemblies that include double glazing.

Suggestions have already been made for this. DE-AS-1212274 shows one Arrangement in which the inner glass pane opposite the outer Glass pane has a peripheral overhang on the edge, with a pure Rotary fitting is provided, which is either cemented or clamped, namely in essential to the supernatant. This arrangement does not allow the use of one Turn / tilt hardware.

DE-U1-93 04 381 shows an arrangement with a spacer, which with the two Glass panes is glued and one in its outward-facing section circumferential groove carries that for receiving a fitting, in particular a turn / tilt Be blow serves. DE-A1-43 43 521 shows a basically similar arrangement, at the spacer is extended on the back so that a circumferential U-shaped Recess is formed, which is approximately flush with the outer pane and the serves to accommodate the turn / tilt fitting. Here too the spacer is between glued the two glass panes.

It has now been shown that wing arrangements designed in this way are those mentioned at the beginning Desire not to satisfy. An important factor is that the The space between the panes of the insulating glazing also over longer periods of use must remain gas-tight on the outside. Even if it is assumed that only the Use an adhesive of the spacer without overfilling to an over longer periods of time can lead to a tight seal between the panes, which According to previous knowledge, it is likely to be extremely difficult to achieve  the intended operation of the fittings forces such that already in a short time the tightness is no longer given. Furthermore, the burdens are below Under certain circumstances also so high that the glass edge splinters, which is also undesirable. Another disadvantage is that the adhesive is environmental, especially the Exposed to solar radiation, which causes increased aging, which in turn occurs Brittleness and therefore leads to leakage. Finally, it should be noted that the out technical reasons necessary coloring in the adhesive connection and in the Spacers lead to considerable aesthetic impairments. In addition, generally the edge of the adhesive bond visible through the glass pane not very straightforward, which is also undesirable for aesthetic reasons.

It is therefore an object of the invention to provide a frameless door or window sash arrangement with double glazing that meets the practical requirements.

In the main patent. . (Patent application 196 28 034.6) has proposed a profile that is independent of the spacer to embed in the usual edge filling, which forces occurring when the fitting is used as intended without disturbing the Tightness can be recorded.

In the additional patent. . (Patent application 196 54 748.2), however, was an arrangement proposed, which also has a profile that is independent of the spacer, is inserted between the panes of glass, but this profile so at a distance of the spacer is arranged between the glass panes, in particular is glued in, the one between him and the elastic that is customary in insulating glazing Edge filling an airspace remains.

This counteracts the risk that due to the air exclusion of the edge filling, usually Thiokol, which becomes brittle and the tightness of the double glazing outside is no longer guaranteed. However, according to the invention, this cavity or Leaving air space, the edge filling is ventilated, which eliminates the aforementioned risk is avoided.  

A further development of the subject of the main patent and the additional patent is indicated by the features of claim 1.

This further development is again due to the features of the subclaims trained.

The fact that the profile according to the present invention only firmly with the circumferential edge overhang of the inner glass pane is connected is particularly glued and against the peripheral edge of the outer Glass pane supports only, even if sealed, are special features of the Manufacture of double glazing not to be considered. It can be serial products act in which then additionally applied the profile designed according to the invention becomes.

The present invention is also characterized by the features of Subclaims of the main patent. . (Patent application 196 28 034.6) and / or des Additional patent. . (Patent application 196 54 748.2) further developed.

It has been found that a very good firm connection between the profile and the inner glass pane is accessible, the mechanical loads withstands the inclusion and the actuation of a fitting in the profile caused.

The use of laminated glass and in particular from Single-pane safety glass for at least the inner glass pane allows more additional improvements. In particular, a peripheral one opaque cover are created that are very accurate in their course is producible and the inevitable manufacturing inaccuracies in the manufacture of Insulating glazing is able to cover. This is detailed in the main patent . . . (Patent application 196 28 034.6). There is also an aesthetic color scheme possible without having to change the outer surface of the glass panes. After all it is  in the case of toughened safety glass in particular, it is easier to provide bores which are suitable for receiving the actuators of the fitting. Especially at Single-pane safety glass has hitherto only been known in the art sector Change options can be used, namely in particular enamelling in the Edge area, on the one hand, a good primer for the adhesive material for both Spacer and profile as well as the edge filling compound and the other Tightness and strength are not affected.

Finally, a safe assignment can be made by appropriately assigning lip seals Sealing to the outside of the wing arrangement used in the frame also achieve high weather loads.

The relevant exemplary embodiments are in the main patent. . . (Patent application 196 28 034.6) explained in detail with reference to FIGS. 3-6. It is therefore express Reference made to this description. The same applies to the on the basis of FIG Main patent. . . (Patent application 196 28 034.6) shown special feature.

The present invention is based on that shown in the drawing Embodiment explained in more detail. The only figure shows schematically in section the edge region of a frameless according to the invention Door or window sash arrangement with double glazing.

As far as possible, the following are the same reference numerals as in the main patent. . . (Patent application 196 28 034.6) and additional patent. . . (Patent application 196 54 748.2) used, with the same effect, the reference numerals a double dash is added.

The figure shows a door or window sash arrangement 1 according to the invention, which is constructed on the principle of insulating glazing. Accordingly, it knows an outer glass pane 2 , an inner glass pane 3 and a spacer 4 . The spacer 4 is of a commercially available type and consists of a hollow profile with a rectangular cross section, in the interior 5 of which a moisture-absorbing material can be accommodated, the interior 5 being connected to the space between the panes via small bores 6 .

As is customary with insulating glazing, the spacer 4 is inserted between them by means of a silicone or butyl adhesive strip 8 at a short distance from the outer edges of the glass pane 2 and 3 . A circumferential edge joint is thus formed which, as is customary with insulating glazing, is provided with an edge filling 9 , which usually consists of thiokol. As a result, the space between the panes 7 is sealed off from the outside in a gas-tight and moisture-tight manner. The space between the panes 7 can, as is also known per se, be filled with a gas or (partially) evacuated.

Main patent and additional patent together is the basic idea of arranging the arrangement which is to accommodate the fitting for actuating a door or window sash arrangement in a profile which is formed separately from the spacer 4 . The present invention is explained in more detail below with reference to the embodiment which is the subject of the additional patent. . . (Patent application 196 54 748.2). However, the principles of the present invention can also be applied to the embodiment that is the subject of the main patent. . . (Patent application 196 28 034), in which the profile is embedded in the edge filling 9 . A separate explanation of this embodiment therefore appears to be unnecessary.

At a distance from the edge filling 9 in the area between the glass panes 2 and 3, however, outside of the spatial overlap is arranged a profile 80 which is separated from the spacer 4 and which has a substantially U-shaped cross section and is open to the outside, and for receiving a fitting , in particular a turn / tilt loading conventional design serves. Further, the internal glass pane 3 has a peripheral edge-side projection 11 relative to the outer glass sheet 2, being based on the inside and the outside lying on the position of the door or window casement arrangement 1 in the installed in a building condition. The profile 80 has an outer leg 81 and an inner leg 82 in cross section, which run essentially parallel to the glass panes 2 and 3 , with the fixed connection to only the glass pane being made via the outer surface of the inner leg 82 with respect to the profile 80 3 takes place, preferably via an adhesive connection. The cross leg 83 connecting the longitudinal legs 81 , 82 is spaced from the edge filling compound 9 in the exemplary embodiment such that an air space 84 is formed between the edge filling compound 9 and the profile 80 . The air space 84 can be further enlarged in that the transverse leg 83 has a recess 85 with respect to the sections of the longitudinal legs 81 and 82 closest to the spacer 4 . In addition, through openings (not shown here) can be provided in the cross leg 83 , through which an air exchange with the air space 84 to the outside is possible, these through openings also being able to accommodate fastening screws.

In contrast to the previous embodiments, the profile 80 is, however, not firmly connected to the outer glass pane 2 , but rather only rests on it, in particular on its circumferential end face 27 . In the exemplary embodiment shown, the transition region between the outer longitudinal leg 81 and the transverse leg 83 of the profile 80 is formed as a bead 86 , one surface of which faces the end face 27 of the outer glass pane 2 . The sealing system advantageously takes place via a sealing compound 88 between the bead 86 and the end face 27 of the outer glass pane 2 .

The bead 86 can be part of an outwardly projecting flap 87 , as is explained in the main patent and additional patent, which in the inserted state can not only serve as a stop for a uniform alignment of the profile 80 with respect to the glass panes 2 and 3 , but also as a means to ensure that water that has penetrated due to weather influences is drained off.

As shown, the tab 87 can furthermore have an elastic lip 89 which rests elastically on the outside of the outer glass pane 2 on the edge side, that is to say close to the end face 27 .

The space between the legs 81 , 82 , 83 of the profile 80 contains a wider outer section 19 ″, which is able to receive and guide the sections of the fitting, and a deeper section 20 ″, which has the projections of the fitting required for actuating elements can accommodate larger dimensions without the movement being disturbed or impaired. Both sections 19 ″ and 20 ″ of the space thus formed are separated from one another by a shoulder 21 ″.

The selected embodiment ensures, on the one hand, good guidance of the profile 80 in the area between the glass panes 2 and 3 , but also good guidance of the fitting accommodated in the profile 80 , without the unnecessary mechanical loads on the spacer 4 on the one hand and on cohesion can be exercised between the glass panes 2 and 3 on the other hand. The provision of the air space 84 prevents the edge filling compound 9 from becoming brittle due to a physical and / or chemical reaction and thereby becoming leaky, as is the case in the additional patent. . . (Patent application 196 54 748.2) is explained.

An enamelling 23 is shown only schematically, which is provided on the inner glass pane 3, running around the edge of the space between the panes 7 , and the width of which is dimensioned such that the spacers 4 and profile 80 as well as the filling 9 between them and the air space 84 are covered. The advantage of such a cover as the enamelling 23 is shown in detail in the main patent and the additional patent. On the one hand, an aesthetically clean finish can be achieved, and aesthetic designs can also be achieved. The enamelling 23 offers a very good primer for both the silicone or butyl strip 8 for the tight fastening of the spacer 4 , and for corresponding adhesives for fastening the profile 80 , and also for the edge filling 9 , so that the gas-tight and liquid-tight Completion of the space between the panes is still guaranteed. So far, good results with enamelling 23 have only been achieved for single-pane safety glass. The use of toughened safety glass for at least the inner glass pane 3 also has the advantage that the through openings which are required for the actuation of the fitting can be attached in a simple and safe manner. In this respect, reference can also be made to the explanation in the main patent and additional patent. In the same way, reference can also be made to the main patent and additional patent for the advantages which are achieved overall by such a frameless door or window sash arrangement.

Since the profile 80 is only used for receiving and guiding the fitting, it can be carried out in a simple manner as a plastic profile, for example in a continuous casting process or injection molding process.

The profile 80 can also be constructed in several parts over the circumference of the wing arrangement, as explained in the main and additional patents. It should be mentioned that the customary fitting is also not shown in the figure of the present additional application.

It should also be mentioned that the profile 80 does not necessarily have to be a plastic profile, but can also consist of another suitable material, for example aluminum, if this is expedient in the respective application, in particular for the firm connection to the peripheral edge 11 of the inside Glass panes 3 .

The assignment of a wing arrangement according to the invention to a frame is shown in the main patent. . . (Patent application 196 28 034.6) with the aid of FIGS. 3 to 6 there explained in detail. Reference is expressly made to these explanations.

There is also pointed out, inter alia, that waterproofness is of great importance to the outside. A contribution to improving the watertightness to the outside is achieved by the tab 87 , which is designed as an outwardly projecting projection, which can have an approximately U-shaped recess which is open in the circumferential direction. This not only enables the installation of additional lips from lip seals of seals fastened in the frame, but also creates an additional obstacle to weather-related penetration of water.

It should also be noted that instead of the cover formed by the enamelling 23 , the cover can also be used, as shown in FIG. 7 of the main patent. . . (Patent application 196 28 034.6) is described in detail. Reference is also expressly made here to these explanations.

As already mentioned, the space between the panes 7 can be filled with a gas or evacuated, as is customary per se. It is also common to carry out coatings on the glass panes 2 , 3 in the intermediate glass space 7 in order to achieve a heat protection, sound insulation and / or radiation protection effect (against UV or IR radiation). Coating materials, layer structures and methods for producing such layers are fundamentally well known.

In the production of insulating glazing and the use of coated glass panes, a coated float glass pane is usually cut, freed of the coating on the edge side and then fed to the assembly. However, this is not possible if a wing arrangement 1 according to the invention is to be produced, which contains an enamelling 23 or a comparable surface treatment of one of the glass panes 2 and / or 3 , or in which a material requiring special treatment is used, such as, for example, toughened safety glass.

In the manufacture of a wing arrangement 1 according to the invention, it is possible to use standard insulating glazing in which a glass pane, which will later be used as an internal glass pane, has an overhang 11 on the edge. Appropriately after the edge filling 9 is solidified, the profile 80 is placed all around it in the area of the protrusion 11 , such that the transition area designed as a bead 86 comes to rest against the end face 27 of the outer glass pane 2 , possibly with the interposition of the seal 88 .

In use, there can now be considerable temperature fluctuations, which can lead to difficulties if the difference in expansion between the glass of the glass pane 3 on the one hand and the material of the profile 80 on the other hand is too great. Tensions can occur which no longer guarantee the safe handling of the fitting or by which the profile 80 can no longer be held on the glass pane 3 .

In this respect, the measures that are included in the Additional patent. . . (Patent application 196 54 748.2) in particular the Fig. 3 and 4 are explained.

In the embodiment shown in the figure, a metal strip 90 is firmly attached to the outward-facing surface of the inner leg 82 of the profile 80 in such a way that the glass pane 3 comes into contact with at least this metal strip 90 via its projection 11 . This measure can additionally achieve that the firm connection between the profile 80 and the glass pane 3 is maintained by gluing even at large temperature differences, as can occur in practice, especially since a material can be selected for the metal strip 90 that can be used as a carrier is more suitable for the adhesive than the material of the profile 80 itself. Aluminum or an aluminum alloy is particularly advantageous.

The metal strip 90 can be used, in particular cast in, by means of suitable measures in the manufacture of the profile 80 . This can be done in particular by anchoring projections, such as the projection 91 of the metal strip 90 . Furthermore, a metal rod, as explained in the additional application, can also be provided in the cross leg 83 .

It is advantageous, however, form a projection of the metal strip 90 as this metal rod 90, which, even further allows an anchoring of the metal strip 90 in the body of the profile 80 and in the region of a bead formed 86 transition area, as shown. This metal rod 92 can have through openings (not shown), on the one hand to enable air exchange with the air space 84 , and on the other hand screws can also be accommodated if this is necessary.

In the exemplary embodiment it is shown that the outer side of the outer longitudinal leg 81 is approximately aligned with the inner surface of the outer glass pane 2 . This has certain advantages in connection with the interaction with lip seals arranged in the frame. It is essential, however, that the outer longitudinal leg 81 is also sufficiently stable so that no problems arise when the fitting is received.

Overall, a frameless door or window sash arrangement is thus created the tightness of the Can guarantee space between the panes, and moreover a great variety aesthetic and architectural effects can be achieved and also the safe trouble-free handling of the fittings is guaranteed.
