DE19654748A1 - Frameless glazing unit e.g. window or door - Google Patents

Abstract

The frameless unit comprises the inside pane (3) extending beyond the integral edge frame for an interior flush finish. A spacer profile (4) set inside the edge of the double glazing with adhesive sealant holds the panes apart. A profiled edge strip (10) has an edge which locates in the unit edge and is secured by sealant. The trapped space (64) between the spacer profile and the edge frame is vented. The single layer safety glass used for the outer and inner panes is coated at the edges to hide the sealing frames. The edge of the outer pane is protected by a lipped profile of the edge strip.

Description

The invention relates to a frameless door or window sash arrangement Double glazing.

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 can also be filled with certain glass mixtures. The glass surfaces can with Thermal protection, sound insulation and / or radiation protection coatings may be provided.

In door arrangements such as those used 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, at least for design reasons, the desire to also include frameless door and To create window sash assemblies that include double glazing.

Suggestions have already been made for this. DE-AS-12 12 274 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, of which the preamble of claim 1 goes out shows a basically similar arrangement, in which the spacer is extended on the back so that a circumferential U-shaped recess is formed, the about flush with the outer pane and the to accommodate the Turn / tilt fitting is used. Here, too, is the spacer between the two glass panes glued in.

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 of 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 been 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 contrast, the present invention proposes an arrangement in which although also a profile that is independent of the spacer between the Glass panes is used, but this profile so far from that Spacer is arranged between the glass panes, in particular is glued that between it and the elastic edge filling that is customary in insulating glazing 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.  

According to another aspect of the present invention, the profile has in its Longitudinal legs and / or his transverse leg channels, into which metal rods can be inserted or are embedded, possibly in sections in at least some of the channels Screws can be included. These metal rods are anti-stretch Elements, causing different expansions of glass pane and profile Changes in temperature can be avoided.

According to a further aspect of the present invention, the outside are facing surfaces of the legs of the profile metal strips firmly attached such that the Place the glass pane at least on the metal strips.

This also serves to compensate for expansion fluctuations in the temperature load between glass and the material of the profile, usually plastic, to compensate for this Metal bar is also the carrier of the adhesive that connects the glass panes and reached the profile.

The invention is further developed by the features of the subclaims. the features further developing the present invention essentially with the Features that match the invention according to the main patent. . . (Patent application 196 28 034.6) further.

It is also essential for the present invention that the now long-standing industrial experience in the production of double glazing with the only one Restriction can be used that outside the backfill sufficient space must remain between the gas disks for the profile to be inserted can be.

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. 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 is only known in the art sector Finishing options can be used, namely in particular enamelling in the Edge area, which on the one hand is a good primer for the adhesive material from 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 to 7. 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 has been described with reference to the drawing Exemplary embodiments explained in more detail. Show it:

Figure 1 shows schematically in section the edge region of a frameless door or window sash arrangement according to the invention with insulating glazing.

Fig. 2 shows schematically a plan view of such a blade assembly,

Fig. 3 shows schematically in section the edge region of another frameless door or window casement arrangement with insulated glazing according to the invention,

Fig. 4 shows schematically in section the edge area of yet another frameless door or window sash arrangement according to the invention with insulating glazing.

As far as possible, the following are the same reference numerals as in the main patent. . . (Patent application 196 28 034.6) used, with the same effect the A dash is added to the reference number.

Fig. 1 shows a door or window casement arrangement according to the invention 1, which is constructed according to the principle of a double glazing. It accordingly points to 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 7 via small bores 6 .

As is usual 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.

According to the invention, at a distance from the edge filling 9 between the glass panes 2 and 3, a profile 60 is used which is separated from the spacer 4 and which has an essentially U-shaped cross section and is open to the outside and which is used to accommodate a fitting, in particular a rotating / Tilt hardware of common 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 cross-section of the profile 60 has an outer leg 61 and an inner leg 62 , which run essentially parallel to the glass panes 2 and 3 , respectively, and via whose surfaces lying outside the profile 60 there is a firm connection to the glass panes 2 and 3 , respectively , preferably via an adhesive connection. The cross leg 63 connecting the legs 60 , 62 is spaced apart from the edge filling compound 9 such that an air space 64 is formed between the edge filling compound 9 and the profile 60 . The air space 64 can be further enlarged in that the transverse leg 63 has a recess 65 with respect to the sections of the legs 61 and 62 closest to the spacer 4 . In the cross leg 63 , through openings 74 can also be provided, through which an air exchange with the air space 64 to the outside is possible, wherein these through openings 74 can also serve to receive fastening screws.

This ensures good guidance of the profile 60 between the glass panes 2 and 3 , specifically also the fitting accommodated in the profile 60 , unnecessary mechanical loads, in particular of the spacer 4 , being avoided. The provision of the air space 64 and the possibility of an air exchange to the outside prevent the edge filling compound 9 from becoming brittle due to physical and / or chemical reactions and thereby becoming leaky.

The space between the legs 61 , 62 , 63 contains a wider outer section 19 ', which is able to receive and guide the sections of the fitting, and a deeper section 20 ', which is able to accommodate the protrusions of the fitting of larger dimensions required for actuating elements, without that the movement was disturbed and impaired. The two sections 19 'and 20 ' of the room are separated from one another by a shoulder 21 '.

In the exemplary embodiment shown, the profile 60 also has an outwardly projecting tab 66 at the end of the outer leg 61 which is distant from the pane interspace 7 and, in the inserted state, as shown, comes to rest on the end face of the outer glass pane 2 . This tab 66 can therefore serve as a stop and thus ensure a consistently uniform alignment of the profile 60 with respect to the gas disks 2 and 3 .

As not shown in FIG. 1, but indicated in FIG. 2, in this exemplary embodiment the inner glass pane 3 can also have an enamelling 23 that runs around the edge of the pane 7 , the width of which is dimensioned such that, as shown in FIG. 2 , Spacer 4 and profile 60 as well as the intermediate filling 9 and the air space 64 are covered.

It has been shown that such a cover as the enamelling 23 can be produced very precisely in its edge course, which is not guaranteed for the laying of the silicone or butyl strips 8 , so that an aesthetically clean finish can be achieved. Furthermore, this enamelling 23 can make the glass opaque in this area and / or design it in a special way in terms of color. This enamel 23 is a special glass-technical action that requires a baking process. Until now this was only known for artistic works. It turns out, however, that despite the enamelling 23 a very good primer for the silicone or butyl strip 8 for the tight fastening of the spacer 4 , for appropriate adhesives for fastening the profile 60 and for the edge filling 9 , so that the gas-tight and liquid-tight closure of the intermediate space 7 is still guaranteed.

So far, good results with enamelling 23 have only been achieved for single-pane safety glass. The use of single-pane safety glass also has the advantage that the through openings that are required for the actuation of the fitting can be attached in a simple and safe manner.

Fig. 2 shows the arrangement of such through holes, in which there is a medium, somewhat larger hole 24 for the passage of the actuating element and two adjacent, somewhat smaller holes 25 for the fastening elements of the actuator. According to the current state of the art, no further holes are required for turn / tilt fittings. Single-pane safety glass has another advantage in that the edges can be ground very well (chamfered), which greatly reduces the risk of injury. In addition, the risk of splintering is greatly reduced.

The advantages of such a frameless door or window sash arrangement with double glazing are obvious. In addition to all the advantages of double glazing, a very high level of light is achieved. The arrangement is also very easy to maintain. In contrast to a conventional frame window, there are no corners and edges, which makes cleaning very easy. Free coloring is also possible, in particular in the case of enamelling 23 . Operation is unchanged compared to conventional frame windows, since identical turn / tilt fittings can be used. From an architectural point of view, the position of permanently installed glass panes and of wing arrangements that can be opened can be chosen arbitrarily for large building surfaces, since the frame is omitted and there are no additional requirements for the frame.

Since the profile 60 is only used to hold and guide the fitting, it can be carried out in a simple manner as a plastic profile, for example in a continuous casting process or an injection molding process.

Since the space between the panes 7 is sealed off from the outside by means of the spacer 4 , the profile 60, seen over the circumference of the wing arrangement, can be constructed in several parts, with no high accuracy being required at the joints. For example, a C-shaped or vice versa C-shaped design can be considered in the circumferential direction of the wing arrangement, as is explained, for example, with reference to FIG. 2. The two profile parts 60 a and 60 b are arranged abutting one another via butt joints 26 '. The position of the butt joints 26 'and their width is determined in such a way that there is no impairment in the movement of the fitting in the room 19 ', possibly also in the room 20 ', but the air exchange with the air space 64 is possible. Of course, another multi-part design of the profile 60 is also possible, and the butt joints 26 'can also be provided at other locations, for example the corners (not shown in detail).

It should be mentioned again that the customary fitting is not shown in any of the figures is.  

It should also be mentioned that the profile 60 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.

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 in that the tab 66 has an outwardly projecting projection 67 , which can have an approximately U-shaped recess 68 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 an 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 customary to carry out coatings on the glass panes 2 , 3 in the glass interspace 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.

When producing a wing arrangement 1 according to the invention, care must be taken that the edge filling 9 is already solidified to such an extent that the edge filling 9 can no longer flow when the profile 60 is inserted. For the rest, the known conventional method for producing insulating glazing can be used. In this respect, the corresponding explanations in the main patent can also be based on the known prior art. . . (Patent application 196 28 034.6).

In use, there can now be considerable temperature fluctuations, which can lead to difficulties if the expansion differences between the glass of the panes 2 , 3 on the one hand and the material of the profile 60 on the other hand are too great. Tensions can occur which no longer guarantee the safe handling of the fitting or which no longer guarantee the hold of the profile 60 between the glass panes 2 and 3 .

The solution to this problem according to the invention is both for the profile 60 according to FIG. 1 of the present application and for the profile according to the main patent. . . (196 28 034.6) applicable. In the present application, this solution is explained in more detail based on further developments of the profile 60 .

According to the embodiment shown in FIG. 3, the profile 60 has in its legs 61 , 62 and / or its cross leg 63 channels 69 and 70 , into which metal rods 75 and 76 can be inserted or can be embedded. However, these channels can also be used to hold screws for fastening the fittings, if necessary additionally and alternately with such metal bars 75 and 76 .

In the exemplary embodiment shown in FIG. 4, metal strips 71 and 72 are firmly attached to the outwardly facing surfaces of the legs 61 , 62 of the profile 60 , such that the glass pane 2 , 3 come to rest at least on the metal strips 71 , 72 .

The measure according to FIG. 4 can additionally achieve that the firm connection between the profile 60 and the glass panes 2 , 3 is maintained by gluing even at large temperature differences, as can occur in practice, especially for the metal strips 71 , 72 Material can be selected that is more suitable as a carrier for the adhesive than the material of the profile 60 itself. Aluminum or an aluminum alloy is particularly advantageous.

The metal strips 71 , 72 can also be used, in particular cast in, by suitable measures in the manufacture of the profile 60 . This can be done, for example, by anchoring projections, such as the projection 73 of the strip 72 in the leg 62 of the profile 60 .

However, other projections can also be used for this purpose, for example projections arranged in a manner distributed over the longitudinal extent of the metal strips 71 , 72 or the like.

Finally, it should be mentioned that the measures according to FIG. 3 and the measures according to. Fig. 4 can be provided together.

Overall, therefore, a frameless door or window sash arrangement is created which can ensure the tightness of the space between the panes 7 which is absolutely necessary for practical applications, a large variety of aesthetic and architectural effects being able to be achieved and the safe, trouble-free handling of the fittings being ensured.
