Abstract

The invention relates to a frameless door, or door or window wing arrangement with insulated glazing. From the conventional structure of insulated glazing a preferably plastic section (10) open externally and having a U-shape is embedded, when separated from the conventional spacer (4), in the conventional edge filling (9) or is attached (60, 80) in such a manner that an air space (64) remains. The section (10; 60; 80) is used to hold a commercially-available turning/ tilting fitting. The required tightness of the intermediate pane space (7) is consequently ensured externally. Using single-pane toughened safety glass and providing enamel (23) or a similar covering in the edge region to cover the spacers (4), edge filling (9), air space (64) and the section (10, 60, 80) is advantageous, as is a sealing system against the surrounding front surface (27) of the external glass pane (2).

FRAMELESS DOOR OR WINDOW CASEMENT ARRANGEMENT WITH
INSULATED GLAZING, AND PROCESS
FOR THE MANUFACTURE THEREOF
The present invention relates to a frameless door or window casement arrangement with insulated glazing.
Usual door and window casement arrangements consist, essentially, of a door or respectively, a window frame in which there is inserted a plate arrangement. The window frame also support the fittings by means of which the arrangement is insertable in a usual mating frame (door jamb or respectively, a window jamb or frame) and is adapted to be pivotable therein and closeable relative thereto. In particular, there are also known socalled turning/tilting fittings, by means of which the window or door casing arrangement can be pivoted or tilted relative to the mating frame in accordance with the position of an actuating handle, whereby in a third position of the actuating handle, by means of the fitting there can be achieved a fixed latching in the mating frame, as a result of which there is achieved a sealed condition with respect to the exterior through the utilization of encompassing seals.
Usually, there are furthermore also employed socalled insulated glazings for this purpose. With regard to the term insulated glazing there is to be understood a plate arrangement consisting of at least two glass plates which are retained at a spacing relative to each other, in which there is gas tightly glued in any encompassing socalled spacer, whereby through a rim filling, in general a Thiokol'1'"' mass, there is achieved a further sealing with regard to the exterior. The spacer contains mostly a moisture-absorbent material, in order to absorb moisture from the tightly closed off plate interspace which is present between the two plates and the spacer. This plate interspace can be evacuated, however, it can also be n~....."."""~,.~... .._...,~"~...._ ,.W ~ , , filled with specified gas mixtures. The glass surfaces can be equipped with heat protective, sound protective and/or radiation protective coatings.
For door arrangements, for example, such as those which are known for sports installations (socalled squash courts), there are already employed single plate glazings without frames. The fittings which are required for the rotational movement of the glazing are clamped thereto or screwed thereon by means of bore holes. In the event that rails are to be attached along the edge, it is also possible to provide for lift fitting arrangements, which, in any event, will again impart a frame-like character.
Due to reasons of configurations it is a wish to also be able to create frameless door and window casement arrangements which contain an insulated glazing.
For this purpose, proposals have already been made. The German Publication DE-AS-1212274 discloses an arrangement in which the inwardly located glass plate possesses a peripherally extending edge projection relative to the exteriorly located glass plate, whereby there is contemplated a purely rotary fitting which is either glued thereon or clamped thereto, and essentially on the projection. This arrangement does not permit the utilization of a turning/tilting fitting.
The German Publication DE-U1-93043$1 discloses an arrangement with a spacer which is glued together with both glass plates and carries a peripheral groove in its outwardly facing section, which serves for the receipt of a fitting, especially a turning/tilting fitting. The German DE-A1-4343521 discloses a basically similar arrangement in which the spacer is extended rearwardly in such a manner that there is formed an encompassing U-shaped recess, which closes off in a generally close fit with the exteriorly located plate and which serves for the receipt of the turning/tilting fitting. Also in this case is the spacer adhesively glued between the two glass plates.

.,". ~_ .",. , ...~"~,~.".".-m.-.

It has been found that such configured kinds of casement arrangements do not satisfy the above-mentioned wish. An important factor resides in that the interspace between the plates of the insulated glazing must remain gas-tightly sealed with respect to the exterior even over lengthier periods of use. Even when one proceeds from the aspect that merely the utilization of a glueing of the spacer without an edge filling may lead to a sealed closure of the plate interspace over lengthier periods of time, which according to current knowledge ~ could be achieved only with extreme difficulties, the forces which are exerted during the specified actuation of the fittings are such that already within a short period of time, there is no longer provided the sealing condition.
Furthermore, the loads under certain conditions are also so high that the glass edge will splinter, which is similarly undesired. A further disadvantage is that the adhesive is exposed to environmental influences, especially to sun rays, as a result of which there is encountered an intense ageing which again, in turn, leads to embrittlement and thereby to a loss in sealing ability. Finally, it must be noted that the coloration which may be necessary due to technological reasons for the adhesive connection and for the spacer can lead to significant adverse aesthetic influences. Moreover the edge of the adhesive connection which is in general visible through the glass plate is not configured quite linearly, which is also undesired due to aesthetic reasons.
Accordingly, it is an object of the invention to provide a frameless door or window casement arrangement with insulated glazing which will fulfill the practical demands.
According to one aspect of the invention, there is provided a frameless door or window casement arrangement with insulated glazing which comprises an externally located glass plate and an inwardly located glass plate with an encompassing edge projection opposite the externally located glass plate.
A spacer is gas-tightly inserted generally along the edge between the inwardly located and externally located glass ~....,.., ..... ,".,..»,~....~.,.~..,..~.. _.. , plates, and a similarly generally U-shaped outwardly opening arrangement, which along an edge encompasses the spacer, is positioned between the glass plates for receiving a fitting.
Actuating elements pass through the inwardly located glass S plate through openings, and facilitate access to the fitting.
The generally U-shaped arrangement is formed by a profile separated from the spacer and is embedded into an elastic edge filling known per se for insulated glazings.
According to another aspect of the invention there is provided a frameless door or window casement arrangement with insulated glazing comprising an externally located glass plate and an inwardly located glass ph.ate with a peripheral edge projection opposite the externally located glass plate. A
spacer is gas-tightly inserted generally along the edge between said inwardly located and externally located glass plates. A
similarly generally U-shaped outwardly opening arrangement encompassing the spacer is positioned between the glass plates for receiving a fitting. Actuating elements of the inwardly located glass plate pass through openings and facilitate access to the fitting. The casement arrangement is characterized by the generally U-shaped arrangement being formed by a profile separate from the spacer, which profile is positioned at such a distance from the spacer between the glass plates, and is glued therein, so that an air space is located between the profile and an elastic edge filling known per se for insulated glazings.
According to a further aspect of the invention, there is provided a method for manufacturing the frameless door or window casement arrangement with insulated glazing of the present invention comprising the steps of:
(a) cutting a float glass plate for the externally located glass plate;
(b) cutting a float glass plate for the inwardly located glass plate;

(c) boring openings for the actuating elements of a fitting in an edge region of the float glass plate for the inwardly located glass plate;

(d) enamelling the edge region of at least the float glass pl ate for the inwardly located glass plate;

(e) heat treating at least the float glass plate for the inwardly located glass plate for burning in the enamelling;

( f ) effecting a concurrent or separate heat treatment of at least the float glass plate for the inwardly located glass plate to form a single-plate safety glass plate;

(g) when required, coating at least one of the glass plates with a heat protective, sound protective, and/or radiation protective layer;

(h) associating, inserting, assembling and glueing of the two glass plates and the spacer for an insulated glazing in a manner known per se;

(i) filling in of an edge filling mass for the insulated glazing in a manner known per se;

(j) pressing the U-shaped profile into the edge filling mass so that the edge filling mass contacts an outwardly projecting flange at a remote end of an outer arm of the profile with an end surface of the outwardly located glass plate;

(k) curing the edge filling mass until reaching the elastic end condition thereof;
and (1) inserting and mounting the fitting and the actuation elements thereof.

The basic concept of the first embodiment of the invention lies in the recognition, that a profile embedded in the usual edge fitting, which is independent of the spacer, is capable of receiving the forces encountered at a specified use of the fitting without disrupting the sealing ability. Thereby, it is also essential that use can be made of the industrial w~.. ""~.,. ~,.""."~.~,...~.,.....~.. .. , experience over the interim of many years in the manufacture of insulated glazings, without any restrictions.
The basic concept of the second embodiment of the invention is an arrangement, in which a similar profile, which is independent of the spacer is inserted between the glass plates, this profile, however, being located at a distance from the spacer between the glass plates, especially glued in, that there remains an airspace between itself and the elastic edge filling with insulated glazing. This will counteract the danger, that because of the air closure of the edge filling, usually ThiokolT'", the latter becomes brittle and the sealing capability of the insulated glazing is no longer afforded towards the exterior. If, however, according to the invention there remains this hollow space or airspace, than the edge filling is aerated, as a result of which there is avoided the mentioned danger. Here it is also important that there can be used the industrial experience which has been employed in the interim for many years in the manufacture of insulated glazings, with the single restriction that, outside of the edge filling, there must remain sufficient space between the glass plates so that there can be inserted the profile.
Pursuant to a further aspect of the present invention, the profile incorporates channels in its longitudinal arms and/or its transverse arm, into which metal rods may be inserted or embedded whereby, as required, in at least a few of the channel sections there can be received screws. These metal rods are expansion-restrictive elements, as a result of which there can be avoided different expansions of the glass plate and profile section during temperature changes.
Pursuant to a further aspect of the present invention, metal strips are applied on the outwardly facing surfaces of the arms of the profile element, in a manner such that the glass plate contacts at least against the metal strips.
Moreover, this also serves the purpose of compensating for fluctuations in the expansion during temperature loading between the glass and material of the profile, which usually ~.~~ _..",. .. . P..,~~...~,.-,,..,~..

consists of plastic material, whereby these metal strips are also carriers for the adhesive, which achieves the connection between the glass plates and the profile element.
When, pursuant to a modification, the profile element of the present invention is merely fixedly connected with the encompassing side edge projection of the inwardly located glass plate, especially glued thereto and merely supports itself against the surrounding edge of the exteriorly located glass plate, even when sealed, then special conditions in the manufacture of the insulated glazing need not be considered.
This can relate to mass-produced items, in which there is then additionally applied the inventively formed profile element.
It has been ascertained that an extremely good fixed connection is attainable between the profile element and the inwardly located glass plate which withstands the mechanical loads which are caused by the receipt and the actuation of a fitting in the profile element.
The utilization of laminated plate glass and especially of single-plate safety glass for at least the inwardly located glass plate, allows for further additional improvements. In particular there can be created a light-impervious covering which extends around the edges, which is extremely precisely manufacturable and which facilitates the covering of the unavoidable manufacturing imprecisions encountered during manufacture of the insulated glazing. Furthermore, it is possible to provide for an aesthetically attractive colored configuration, without having to change the external surface of the glass plate. Finally, it is possible more simply for especially a single-plate safety glass to provide bore holes which are adapted for the receipt of the actuating elements of the fitting. In particular, with single-plate safety glass there can be employed decorative capabilities which are merely known in the artistic sector, namely especially an enamelling along the edge region which affords, on the one hand a good adhesive background for the glue adhesive material and the edge w. .."..... ",..r~a",~"H"M,"~""~..,...... , filling mass, and on the other hand, which will not adversely influence the sealing capability and strength.
Finally, through a suitable association of lip seals there can be achieved a secure sealing toward the exterior of the S casement arrangement which is inserted into the mating frame even under extensive weathering.
The inventive process for the manufacture of a door or window casement arrangement with insulated glazing pursuant to the first embodiment utilizes most extensively known process steps, whereby merely another sequence of steps is required, and for an artistic working of float glass, known enamelling can be industrially implemented.
The invention is now explained more closely on the basis of the accompanying drawings illustrating examples of embodiments, in which;

Figure 12 illustrates schematically in section the edge region of a further inventive frameless door or, respectively, window casing arrangement with insulated glazing.
Figure 1 illustrates an inventive door or window casing arrangement 1, which is constructed in accordance with the principle of an insulated glazing. Accordingly, it is provided with an outwardly or externally located glass plate 2, an inwardly located glass plate 3 and a spacer 4. The spacer 4 is of commercially usual constructional type and consists of a hollow profile element of rectangular cross-section, in the inner space 5 of which there can be received a moisture-absorbent material, whereby the inner space 5 stands in connection with the plate interspace 7 through small bore holes 5.
As is usual with insulated glazings, the spacer 4 by means of silicon or butyl adhesive strips 8 is inserted between the glass plates 2 and 3 at a small distance from the outer edges of the latter. Thereby, formed is an encompassing surrounding edge joint, such as is usual for insulated glazings, which is provided with an edge filling 9, which usually consists of ThiokolT"'. Thus, the interspace 7 between the glass plates 2 and 3 is sealed with respect to the exterior in a gas and moisture-sealed type manner. The plate interspace 7, as is known per se, can be filled with a gas or (partially) evacuated.
Pursuant to the first embodiment of the invention in the edge filling 9 there is embedded a profile element 10 which is separated from the spacer 4, which comprises an essentially U-shaped cross-section and which is open towards the outside and which serves for the receipt of a fitting, especially a turning/tilting fitting of a usual type of construction.
Furthermore, the inwardly located glass plate 3 possesses a _. _. . ..~_..~~"~, .~, surrounding edge projection 11 opposite to the externally located glass plate 2.
The profile element 10 comprises in cross-section an outwardly located arm 12 and an inwardly located arm 13, which extend essentially in parallel with the glass plates 2 and 3 respectively; however, which possess a small spacing so that there can be implemented the embedding into the edge filling 9. A connecting or transverse arm 14, which due to manufacturing reasons can possess a hollow space 15, can incorporate ridges 16 on the outside which faces towards the spacer 4, and which affords an improved embedding. Both arms 12 and 13 support themselves by means of small beads 17 and 18;
respectively, essentially linearly on the associated glass plate 2 and 3, respectively, whereby this support is effected essentially at the end of the arms 12 and 13, respectively, which are distant from the plate interspace 7, as is illustrated.
This will not only avoid the escape of the mass of the edge filling during the embedding, but will also ensure that there is a good guidance of the profile element 10 between the plates 2 and 3, and thereby of the fitting which is received in the profile element 10, such that any unnecessary mechanical stresses are avoided.
The space between the arms 12, 13 and 14 comprises a broader outer section 19 which allows for receiving and guiding flat sections of the fitting, and a deeper section 20 which is adapted to receive projections of the fittings having larger dimensions which are required for actuating elements of the fitting, the movement thereof not being disturbed or adversely influenced. The two sections 19, 20 of the space are separated from each other by a shoulder 21.
The hollow space 15 in the transverse arm 14, which is provided due to manufacturing reasons, however, also facilitates that the section which comprises the ridges 16 can elastically deflect in the event that this becomes necessary.

,_....... ..~."",."F~s»~,-~~.

In the illustrated embodiment, the profile element 10 further comprises at the end of the externally located arm 12 which is distant from the plate interspace 7 an outwardly projecting flange 22, which in the embedded position as illustrated comes into contact against the end surface of the externally located glass plate 2. The flange 22 can thus serve as a stop and thereby assure a throughout uniform orientation of the profile element 10 relative to the glass plates 2 and 3.
In the embodiment illustrated in Figure l, the inwardly located glass plate 3 possesses an enamelling 23 which extends around the edge facing towards the plate interspace 7, the width of which is so dimensioned, as represented, that the spacer 4 and the profile element 10, as well as the edge filling 9 therebetween are covered.
It was found that such type of covering, such as the enamelling 23, in its edge region can be produced extremely precisely, which is not afforded for the positioning of the silicon or butyl strips 8, so that there can be achieved an aesthetically clean closure. Furthermore, this enamelling 23 renders the glass in this region opaque and/or colored in a particular manner. This enamelling 23 is a special glass technological treatment which requires a heat etching procedure. Heretofore this was only known with artistic work.
However, it turned out that notwithstanding the enamelling 23 there is achieved a very good adhesive base for the silicon or, respectively, butyl strips 8, and also for the edge filling 9, so that gas tight and liquid tight closure is achieved for the plate interspace 7.
Good results with the enamelling 23 could heretofore only be achieved for single-plate safety glass. The employment of single-plate safety glass has additionally the advantage that through-openings which are required for the actuating elements of the fitting can be applied in a simple and secure manner.
Figure 2 illustrates the arrangement of such through bores, whereby this relates to a middle somewhat larger bore m .... ,,. ".,."~._,- ... ,. . , 24 for the through passage of the actuating element, and to neighbouring somewhat smaller bores 25 for the fastening elements of the actuating element. Further bores are not required in accordance with the present state of the technology for turning/tilting fittings. Single-plate safety glass has also the further advantage that the edges can be easily polished (chamfered) whereby the danger of injury is extensively avoided. Moreover, there is also quite reduced the danger of any glass splinters.
The advantages of such a frameless door or window casement arrangement with insulated glazing are apparent. Besides all advantages of an insulated glazing there is achieved an extremely high light through-flow. Furthermore, it is easy to take care of the arrangement. In contrast with a usual framed window, there is no presence of any corners or edges, which facilitates cleaning. Furthermore, it is possible to have a free color selection, especially for an enamelling 23. The servicing is unchanged with regard to usual framed windows, inasmuch as identical turning/tilting fittings can be employed.
Architecturally viewed, for large building surfaces, the position of fixedly installed glass plates and of casement arrangements which can be opened, can be suitably selected, since the frames are eliminated and also for shutter frames there are no additional requirements to be considered.
Inasmuch as the profile element 10 serves merely for the receipt and guidance of the fitting, it can be constructed in a simple manner as a plastic material profile, for example, in an extrusion process or an injection molding process.
Inasmuch as the plate interspace 7 by means of the spacer 4 is sealingly closed with respect to the exterior, the profile element 10 can be constructed in multiple parts around the circumference of the casing arrangement, whereby at joint locations there need not be considered any high precision. For example, there can be contemplated a construction which, in the circumferential direction of the casement arrangement, has a C-shaped or inverted C-shaped configuration, such as is .~ .~.. . ....~ ..,~.",,~+~.....,...~ ~.,...~ , elucidated, for example, with regard to Figure 2. Two profile parts l0A and lOB are arranged so as to contact each other by means of contact joints 26. The position of the contact joints 26 and the width thereof is so determined, that any mass of the edge filling 9 which escapes during embedding will not have any influence during the movement of the fitting in the space 19 or, respectively, occasionally also in the space 20. Also in this instance can the hollow space 15 in the transverse arm 14 be of significance. This facilitates also the embedding since during the embedding, the displaced air can escape in a simple manner. Of course it is also possible to have a multi-part construction of the profile element 10, and the contact joints 26 can also be provided at the corners (not shown in detail).
On the basis of Figures 3 through 6 there are described herebelow different embodiments with association to a mating frame 30, whereby the same reference numerals as in Figure 1 designate the same components, and whereby deviations therefrom are elucidated.
Furthermore, it is to be noted that, for example, in the profile element 10, the hollow space 15 and the ridges 16 are not particularly illustrated. Of course, those can be present in the shape as in Figure 1 or in a similar form. Furthermore, there is not illustrated in detail, that the beads 17 and 18 (Figure 1) can comprise taperings which are of assistance in the manufacturing technology. In this connection, it is to be mentioned that the profile element 10 need not be necessarily a plastic material profile, but can also be constituted of another suitable material; for example, aluminum, when this is suitable for a particular use.
Furthermore, it is also again to be mentioned that in none of the figures is there illustrated the commercially usual fitting.
Quite in general is the casement arrangement 1 inserted into a mating frame 30, whereby there is only represented the closed position, in which the fitting which is received in the profile element 10, through engaging means (not shown) is .,.~.~M.".,",. .,.."...~w."..."~.....~ . ..

engaged in suitable grooves 31 in the mating frame 30, as is known per se.
The mating frame 30 is fixedly anchored in the building in a known manner which is not illustrated in detail. In Figures 3 and 4, the mating frame 30 is formed by a socalled thermally separated aluminum profile, i.e., through an inner profile 32, heat-isolating connecting elements 33, 34, and an external covering profile element 35. The covering profile element 35 projects ahead relative to a window or door opening to be closed in such a manner, that in the closed condition of the casement arrangement 1 the edge region thereof comes into a sealing contact against the covering profile element 35 by means of a sealing element. In Figures 3 and 4, the element of the covering profile 35 which projects the furthest into the window opening and comes closest to the casement arrangement 1, carries a lip seal 36. The position of this lip seal 36 in the exemplary embodiment is such that, viewed from the outside, through the lip seal 36 and the covering profile element 35, there is covered the region of the externally located glass plate 32 of the casement arrangement l, which is associated with the spacer 4, the edge filling 9 and the profile element 10. A covering, such as the enamelling 23 as represented for the inwardly located glass plate 3 (Figures 1 and 2), is thereby not necessary in this region. For another configuration of the association of lip seal 36 and covering profile 35 with regard to the casement arrangement 1, there can, however, be also provided for the externally located plate 2, a covering which corresponds to the enamelling 23 (not shown) .
Pursuant to Figure 3, at a portion of the covering profile which is proximate to a building, there is retained a further lip seal 37, whose lip comes into contact against a portion of the profile 10. In this exemplary embodiment, the flange 22 is not provided at the outermost end of the outwardly 35 located arm 12 which is distant from the plate interspace 7, but evidences a certain spacing, through which there is defined .,.... ".,_ . ~,.~,~",._...

a support surface 38 on the profile 10, against which lip seal 37 comes into contact when the casement arrangement 1 is in the closed condition. Figure 3 also provides indications with regard to the dimensioning of the projection 11 of the inwardly located glass plate 3. This projection is to be dimensioned so that at an open casement arrangement l, the elements of the fitting which project away from the plate interspace 7 will not be disruptive, especially will not be visible in the closed condition of the casement arrangement l; however, the engagement thereof into groove 31 upon actuation of the actuating element (not shown) will be afforded.
In the embodiment pursuant to Figure 3, the covering profile 35 is further configured so that between the outwardly located lip seal 36 and the inwardly located lip seal 37 there is defined a hollow space 39 in which, notwithstanding the lip 36, any penetrated water can run off and, when required, can be guided through openings.
Figure 4 illustrates in contrast a somewhat modified arrangement and construction of the second lip seal, which is here identified by reference numeral 40 and which possess a lip 41 coming into contact against the outwardly located glass plate 2, and a second lip 42 which comes into contact with an end surface of the profile 10. Besides the hollow space 39, there is accordingly defined between the lips 41 and 42 a further hollow space 43, which can similarly serve for the receipt of water which has penetrated notwithstanding all previous sealing measures.
Figure 5 distinguishes from Figures 3 and 4, in that the mating frame 30 is formed by a wood or plastic material profile element 44, in which there is inserted a further configured lip seal 45 which is comparably slightly different from lip seal 36 and a further slightly modified lip seal 46 comparable with lip seal 40. Figure 6 illustrates similarly a wood or plastic material profile 47 for the mating frame, whereby this profile 47 is; however, covered on the outside by further metal profile 48 such as an aluminum profile, which carries the lip seal 36, _. ~ ..m.~...~. "~.."...,..~,.,.."~....".,.,.... _ , whereas the lip seal 46 as heretofore is inserted into the wood or plastic material profile 47. It has been found that the inventive casement arrangement 1 is insertable into mating frames 30 of most differently configured shapes, whereas through the casement arrangement 1 there can be achieved basically required aesthetic effects, without neglecting the sealing.
On the basis of Figure 1 there was shown that the enamelling 23 produces an optical covering, whereby there is concurrently afforded a good adherence for the silicon or, respectively, butyl strips 8, as well as for the edge filling 9. This can also be achieved in a different manner, for example, in a laminated glass plate arrangement 50 pursuant to Figure 7. This consists of (at least) two glass plates 51 and 52 between which there is layered laminate-like a transparent plastic foil 53. This plastic foil 53 is at the edge thereof either rendered opaque through a treatment or replaced by an opaque; or for example, colored foil 54, whereby the same effect is achieved as would be by means of enamelling 23. Of course, in this region there can also be carried out a treatment of one of the glass plates 51 or 52 in order to achieve the same effect. It is important, as mentioned, that the optical covering of the region in which there are located the spacer 4, the edge filing 9, and the profile 10, are under the concurrent maintenance of the adherability with respect to the edge filling 9 and the silicon or, respectively, butyl strips 8. Of course, it is also possible to provide combinations of laminated glass plate arrangements and single-plate safety glass arrangements.
As already mentioned, the plate interspace 7 is fillable with a gas or evacuable, as is usual. It is further usual to undertake in the glass interspace 7 coatings of the glass plates 2, 3 in order to achieve a heat protective, sound protective and/or radiation protective effect (against UV or IR radiation). Coating materials, layered constructions and methods for producing such layers are basically known in many modes.
During the manufacture of insulated glazings with the utilization of coated glass plates, there is usually cut to size a coated float-glass plate, freed along the edge thereof from the coating and then conducted to the assembly. This in any event, is not possible when there should be produced an inventive casement arrangement 1, which contains an enamelling 23 or a comparable surface treatment of one of the glass plates 2 and/or 3, or in which there is employed a material which requires a special treatment; for example, single plate-safety glass.
Furthermore, during embedding of the profile 10 into the edge filling 9 there must be taken care that this embedding is effected as long as the material which is employed for the edge filling 9 and the already filled in material is still deformable, possesses at least a viscous consistency. In accordance therewith, the known, usual process for producing insulated glazings in specified steps must be modified and changed.
Initially, the glass plates 2 and 3 are to be cut to size in their dimensions, commencing from a usual float-glass plate.
Thereafter, the mentioned openings 24 and 25 are forward and enamelling 23 is to be undertaken. In order that the enamelling 23 penetrates into the glass material of the glass plates 2 and 3, respectively, and achieves the necessary adhesive base, the enamelling 23 is to be burnt in within the scope of a heat treatment. Inasmuch as enamelling 23 in accordance with the present state of the technology is only durable for single-plate safety glass, the necessary heat treatment which is employed for the production of the single-plate safety glass is to be implemented concurrently or at a different separate time.
In the event that the glass plates 2 and/or 3 are to be coated, then the coating procedure is to be implemented, whereby subsequent to the.coating procedure, the region in rF ..n.,. .

which there are to be provided the spacer 4, the profile element 10 and the edge filling 9, is to be freed from the coating, or again freed therefrom.
Thereafter, in a usual manner, such as is known for insulated glazings, there is implemented the assembly, meaning, the spacer 4 is provided with the silicon or butyl strips 8 and inserted between the plates 2 and 3 at the intended locations.
Thereafter, there is implemented the edge filling, which is usually effected with ThiokolTM. Prior to the ThiokolT" edge filling 9 reaching its cured elastic condition and being still viscous, the profile 10 is embedded through pressing into the edge filling 9. Only then are there undertaken the necessary steps, such that the edge filling 9 is imparted the necessary solid yet elastic consistency.
A commercial usual turning/tilting fitting can then be inserted and mounted together with the associated actuating elements, for which there are provided the bores 24 and 25.
Thereby, it is necessary that at least the bore 24 is extended through the profile 10 insofar as during the preparation of individual profile parts (for example, l0a and 10b) at suitable locations. At this time, the casement arrangement 1 can then be inserted into the window opening or respectively, into the mating frame 30 thereof, in the usual manner and is ready for operation.
In the following description of a second embodiment as well as of further exemplary embodiment, to the extend possible the same reference numerals are used as in Figures 1 through 7, whereby when showing the same element there is provided a dash to the reference numeral concerned.
Pursuant to the second embodiment in accordance with Figure 8 through 11, at a spacing from the edge filling 9 between the glass plates 2 and 3, there is inserted a profile element 60 which is separate from the spacer 4, and which comprises an essentially U-shaped cross-section and which is open towards the exterior, and which serves for the receipt of a fitting, especially a turning/tilting fitting of usual type ,.. i ,~,:., .~

of construction. Furthermore, the inwardly located glass plate 3 comprises a peripherally extending edge projection 11 relative to the outwardly located glass plate 2, whereby inwardly located and outwardly located relate to the position of the door or window casement arrangement 1 in a condition as installed into a building. The profile 60 comprises in cross-section an outwardly located arm 61 and an inwardly located arm 62, which extend essentially in parallel with the glass plates 2 and 3, respectively, and through which relative to the profile 60, the outwardly located surfaces effect the fixed connection to the glass plates 2 and 3, respectively, preferably through an adhesive connection. A transverse arm 63 which connects the arms 61, 62 is spaced from the mass of the edge filling 9 in such a manner that there is formed an airspace 64 between edge filling 9 and profile 60. The airspace 64 can be further increased by providing in the transverse arm 63 relative to the portions of the arms 61 and 62 nearest to the spacer 4 a setback 65. In the transverse arm 63 there can additionally be provided through-openings 74 which facilitate an air exchange with the airspace 64 towards the outside, whereby these through openings 74 can also serve for the receipt of fastening screws.
Assured hereby is a good guidance of the profile 60 between the glass plates 2 and 3, and namely also of the fitting which is received in the profile 60, whereby there are avoided unnecessary mechanical loads, especially those acting on the spacer 4. Through the provision of the airspace 64 and the possibility of an air exchange with the outside there is avoided that the mass of the edge filling 9 will be embrittled due to physical and/or chemical reactions, and thereby loses its sealing effectiveness.
The space between the arms 61, 62 and 63 contains a wider outer section 19', which enables the receiving of and guidance of the sections of the fitting, and a deeper section 20' which facilitates receiving projections of the fitting of larger dimensions which are required for the actuating elements, . , . " i. ..",.~

without that the movement is disturbed and adversely influenced. The two sections 19' and 20' of the space are separated from each other by means of a shoulder 21'.
In the illustrated exemplary embodiments, the profile 60, at the end of the outwardly located arm 61 which is remote from the plate interspace 7, comprises an outwardly projecting flange or rim 66, which in the inserted condition, as illustrated, comes into contact against the end surface of the externally located glass plate 2. This rim 66 can therefore serve as a stop and thus ensure a throughout uniform orientation of the profile 60 relative to the glass plates 2 and 3.
In this embodiment, the inwardly located glass plate 3 can also comprise an enamelling 23 extending around its edge (not shown in Fig. 8, see Fig. 9), which faces towards the plate interspace 7, whose width is so dimensioned, that as illustrated in Figure 9, the spacer 4 and the profile 60 are covered, as well as the edge filling 9 located therebetween and the airspace 64.
It must be further mentioned that the profile 60 need not necessarily be a plastic material profile, but can also consist of another suitable material, for example, aluminum, as is expedient for a particular instance of utilization.
The association of an inventive casement arrangement with a mating frame is already extensively explained with regard to preceding Figures 3 through 6. Accordingly, reference is made to those explanations.
Therein, among other aspects, as already pointed out, the sealing effect with regard to water toward the exterior is of great significance. In addition to the improvement of the sealing effect against water towards the exterior is achieved in that the flange or rim 66 comprises an outwardly extending projection 67, whereby the latter can show a generally U-shaped recess 68 which is open in circumferential direction. Hereby, there is facilitated the contact of further lip seals which are . n, .,.. 1 ,.. ~M, ~. , fastened in the mating frame, additional obstruction to weather-caused inflowing penetration of water.
Furthermore, it has been found that instead of the covering which is formed by enamelling 23 there can also be employed the covering as is extensively described in Figure 7.
Hereby, there is similarly made specific reference to these explanations.
In the manufacture of the casement arrangement 1 pursuant to this embodiment of the invention, case must be taken that the edge filling 9 is already solidified to such an extent that during the insertion of the profile 60 the edge filling 9 can no longer flow. For the remainder, reference may be made to the known usual process for the manufacturing of insulted glazings.
During use there can be encountered significant temperature fluctuations which, when.the differences in the expansion between the glass of the plates 2 and 3, on the one hand, and of the material of the profile 60, on the other hand, are excessively large can lead to difficulties. This can generate stresses which no longer allow for the secure handling of the fitting, or through which is no longer afforded the retention of the profile 60 between the glass plates 2 and 3.
The inventive solution of this problem is applicable to the profile 60 pursuant to Figure 8, as well as to the profile 10 pursuant to Figure 1. However, this solution is merely explained further on the basis of modifications of profile 60.
In accordance with the embodiment illustrated in Figure 10, the profile 60 comprises channels 69 or 70, respectively in its arms 61, 62 and/or in its transverse arm 63, into which there can be inserted or embedded metal rods 75 and 76, respectively. These channels can, however, also be employed for the receipt of screws for the fastening of the fittings, possibly additionally to or alternatingly with such metal rods 75 and 76, respectively.
In the embodiment illustrated in Figure 11, metal strips 71 and 72, respectively are fixedly attached to the outwardly ,Ii.n",..

facing surfaces of the arms 61, 62 of the profile 60, in such a manner that the glass plate 2, 3, come into contact with at least the metal strips 71, 72.
The measure according to Figure 11 can additionally achieve that the fixed connection between the profile 60 and the glass plate 2, 3 is maintained through adhesives also under intense temperature differences, such as may be encountered in actual practice, in that there is selected a material for the metal strips 71, 72 which is better suited as a support for the adhesive than the material of the profile 60 itself. Of particular advantage is aluminum or aluminum alloy.
The metal strips 71, 72 can be inserted through suitable measures together with the manufacture of the profile 60, especially by being molded therein. This can, for example, be carried out by means of anchoring projections, such as for example, projection 73 of the strip 72 in the arm 62 of the profile 60.
However, other projections can be employed for this purpose, such as projections provided over the longitudinal extension of the metal strips 71, 72 or the like, which are arranged distributed thereon.
Finally, there is to be mentioned that the measures according to Figure 10 and the measures according to Figure 11 can be jointly provided.
Figure 12 similarly illustrates an inventive door or window casement arrangement 1 which is constructed in accordance with the principles of an isolated glazing. This construction can be basically applied to a profile pursuant to Figure 1 as well as a profile pursuant to Figure 8.
Pursuant to Figure 12, at a spacing from the edge filling 9 in the region between the glass plates 2 and 3; however outside of the spatial covering, there is arranged a profile 80 which is separated from the spacer 4, which comprises an essentially U-shaped cross-section and which is open towards the outside and serves for the receipt of a fitting, especially of a turning/tilting fitting of the usual type of construction.

..

Furthermore, the inwardly located glass plate 3 comprises an encompassing edge projection 11 relative to the exteriorly located glass plate 2, whereby the inwardly located and outwardly located position of the door or window casement arrangement 1 relates to a position as installed in a building.
The profile 80 comprises in cross-section an outwardly located arm 81 and an inwardly located arm 82, which extend essentially parallel to the glass plates 2 and 3, respectively, whereby the outer surface of the inwardly located arm 82 relative to the profile 80 provides for the fixed connection to only the glass plate 3, preferably through an adhesive connection. A
transverse arm 83 which connects the longitudinal arms 81, 82 is spaced from the edge filling mass 9 in this exemplary embodiment in such a manner as to form an airspace 84 between the mass of the edge filling 9 and the profile 80. The airspace 84 can be still further increased in that the transverse arm 83 relative to the section of the longitudinal arms 81 and 82 which are closest to the spacer 4 comprises a setback 85. In the transverse arm 83, there can additionally be provided suitable through-openings (not shown), through which there is possible an air exchange with the airspace 84 towards the exterior, whereby these through openings can also serve for the receipt of fastening screws.
The profile 80, in contrast with the previous embodiments, however, is not fixedly connected with the externally located glass plate 2, but merely lies sealingly against the latter, especially along its encompassing end surface 27. In the illustrated exemplary embodiment, the transitional region between the outwardly located longitudinal arm 81 and the transverse arm 83 of the profile is formed as a bead or projecting edge 85, whose one surface is opposite to end surface 27 of the externally located glass plate 2.
Advantageously the sealing contact is effected through a sealing mass 88 between the bead 86 and the end surface 27 of the externally located glass plate 2.

. ._ i """ ., The bead 86 can be a component of an outwardly projecting flange 87, as has previously been already explained, which in the inserted condition does not only serve as a contact or stop for a uniform orientation of the profile 80 relative to the glass plates 2 and 3, but also serves as a means for guiding off any water which has penetrated due. to weathering influences.
The flange 87, can as illustrated further comprise an elastic lip 89 which elastically contacts, in effect, proximate the end surface 27, against the outside of the externally located glass plate 2.
The space between the arms 81, 82, 83 of the profile 80 contains a wider outer section 19", which can receive and guide the sections of the fitting, and a deeper section 20" for the receipt of larger projections of the fittings which are required for the actuating elements, without that the movement thereof is disturbed or adversely influenced. Both sections 19" and 20" of the thus formed space are separated from each other by a shoulder 21".
Through the selected embodiment there is assured, a good guidance of the profile 80 in the region between the glass plates 2 and 3, but also a good guidance of the fitting which is received in the profile, without that this causes, on the one hand, any unnecessary mechanical loads to the spacer 4 and, on the other hand, to the connection between the glass plates 2 and 3. Through the provision of the airspace 84 there is avoided that the mass of the edge filling mass 9 will become embrittled due to physical and/or chemical reactions, and thereby loses its sealing effect, as has been explained hereinabove.
Merely schematically represented is an enamelling 23 which is provided on the inwardly located glass plate 3 extending around the edge facing towards the plate interspace 7, and whose width is so dimensioned that the spacer 4 and the profile 80, as well as the edge filler 9 located therebetween, and the airspace 84 are covered. The advantage of this type of . .,....a .,...~ ..., covering, such as the enamelling 23, is further extensively illustrated hereinabove.
Inasmuch as the profile 80 serves merely for the receipt and guidance of the fitting, it can be constructed in a simple manner as a plastic material profile; for example, by an continuous extrusion processor injection molding process.
The profile 80, around the circumference of the casement arrangements, can be constructed by a plurality of parts, as further explained hereinabove. It is to be mentioned, that also in Figure 12, the commercially usual fitting is not illustrated.
It can be further mentioned, that the profile 80 need not necessarily be a plastic material profile, but can be constituted of another suitable material, for example aluminum, when this is expedient for a particular case of utilization, especially for the fixed connection with the encompassing edge protection 11 of the inwardly located glass plate 3.
An addition to the improvement of the sealing ability against water entering from the exterior is achieved by the flange 87 which is constructed as an outwardly projecting protuberance, whereby this can show a generally U-shaped recess which is again in the circumferential direction.
As a result, there is facilitated the contact of further lips of lip seals of sealing arrangements which are fastened in the mating frame, which also constitutes an additional obstruction to the entry of water caused by weathering conditions.
Furthermore, it should be noted, that instead of the covering which is formed by the enamelling 23, there can also be employed the covering which is described extensively with regard to Figure 7.
In the manufacture of an inventive casement arrangement 1 in accordance with this embodiment, there can be made use of insulated glazing which are mass produced, in which a glass plate which is later employed as the inwardly located glass plate comprises a projection 11 along its edge. Expediently, , , "..,i. ""A ....

after the filling 9 has solidified, the profile 80 is positioned in the region of the projection 11 along the circumference thereof, whereby the transitional region which is formed as a bead 86 comes into contact against the end surface 27 of the externally located glass plate 2; as required, with the interposition of the seal 88.
During use there can be encountered significant temperature fluctuations which, on the one hand, when the differences in the expansion between especially the glass of the glass plate 3, and on the other hand, the material of the profile 80 is too excessive, can lead to difficulties. There can be generated stresses which no longer allow for the secure handling of the fitting, or through which the retention of the profile 80 on the glass plate 3 is no longer afforded.
To that extent there can be basically made use of the measures which are explained with regard to Figures 10 and 11.
In the embodiment illustrated in Figure 12, a metal strip 90 is fixedly attached to the outwardly facing surface of the inwardly located arm 82 of the profile 80, in such a manner that the glass plate 3 by means of its projection 11, comes at least into contact with this metal strip 90. This measure can additionally achieve that the fixed connection between the profile 80 and the glass plate 3 will be maintained through adhesion even under intensive temperature differences, such as are encountered in practice, in that for the metal strip 90 there can be selected a material which is better adapted as a support for the adhesive material than that of the profile 80 itself. For instance, aluminum or an aluminium alloy, is particularly advantageous.
The metal strip 90 can be inserted or, in particular, cast in through suitable measures during the manufacture of the profile 80. This can be effected in particular through anchoring projections, such as for example, projection 91 on the metal strip 90. Furthermore, there can also be additionally provided a metal rod, as mentioned further hereinabove, in the transverse arm 83.

r~ ..... z ., It is, however, advantageous to provide as a projection of the metal strip 90 this metal rod 92, which facilitates the anchoring of the metal strip 90 and the body of the profile 80, as well as the region of the transitional region which is formed as the bead 86, as is illustrated. This metal rod 92 can have through openings (not shown) which facilitate an air exchange with the airspace 84 whereby moreover there can also be received screws in the event that this is required.
In the described embodiment there is illustrated that the outwardly located side of the outwardly located longitudinal arm 81 is generally in an alignment with the inwardly located surface of the externally located glass plate 2. This has certain advantages in conjunction with the cooperation of the lip seals which are arranged in the mating frame. However, it is important that also the outwardly located longitudinal arm 81 is sufficiently stable, so that no problems are encountered upon receipt of the fitting.
There is still to be mentioned that, already in conjunction with the insulated glazings there can be applied known measures for creating the impression of a lattice window or a bulls-eye-glass in the same manner, whereby additionally there can be made use of the measure of the enamelling pursuant also for this purpose.
In total there is created a frameless door or respectively, window casement arrangement, which can afford for practical application the necessarily required sealing capability of the plate interspace 7, whereby in addition, there can be achieved a multiplicity of aesthetic and architectural effects, and further the secure undisturbed manipulation of the fittings.
