Description

The present invention relates to a composite frame for insertion into a building opening, in particular window and door openings. In particular, the present invention relates to a window or door frame, which is composed of composite materials in composite technology.

Window and door frames are traditionally made of wood, metal or plastic. In recent years, increasingly window frames made of glass fiber reinforced plastic (GRP) have been used, also composite window frames made of wood and aluminum are known.

Typically, in the production of windows, insulating glasses in a frame made of wood, plastic or aluminum are clogged. The window opening wings are stiffened by the blocking of the discs in the frame. The resulting forces in the frame are forwarded via the frame corners and determine the dimensioning of the frame. In wood-aluminum composite frames, the wooden frames are protected from the weather by an external aluminum frame, whereby the high thermal conductivity of aluminum leads to undesirable thermal bridges in the frame cross-section.

From the EP 0 586 213 A1 For example, a composite material consisting of polymer and wood fibers that can be extruded into a window frame is known.

The EP 1 106 770 A1 describes a carrier, which is glued to a central portion on an inner side of a disc and is in a form-fitting manner with a leg and by its inherent elasticity on a frame part in engagement.

In contrast, according to the invention a composite frame and an adapter profile for a window or a door with a very small frame cross-section, i. with a small face width of the frame, proposed.

The composite frame according to the invention has a (in the installed state) fixed first frame portion. At this first frame portion, a second, openable frame portion is articulated. The openable second frame section, in turn, includes an inner (i.e., in-installed state inside the building) sash profile. At one (again related to the installed state) outwardly facing side (weather or weather side) of the inner sash profile is a fixedly connected to the sash profile adapter profile is provided, which serves for fixed receiving a window provided therefor.

The first, fixed frame portion has a (in the closed state) around the inner sash profile of the openable second frame portion substantially encircling inner frame profile. At a side facing the building exterior side of the circumferential inner frame profile, a fixedly connected to the peripheral inner frame profile outer visible part is provided.

In technical terminology, the fixed first frame section is referred to as a frame and the openable second frame section is referred to as a sash frame. These terms are used below. Accordingly, the building inside arranged profile of the frame as the inner frame profile and the building inside profile of the sash are referred to as inner sash profile.

The disc and the adapter profile are connected substantially circumferentially with each other so that the adapter profile with the disc forms a self-supporting, rigid unit. This fixed connection can be realized for example by gluing the disc with the adapter profile or other suitable connection technology.

Furthermore, the firm connection of the adapter profile with the inner casement profile and the firm connection of the outer viewing part with the inner window frame profile, for example, also by gluing and / or by screwing done. However, other suitable forms of attachment are possible.

For this purpose, the cross section of the adapter profile comprises a central portion for connecting the adapter profile with the disc and at least one first leg for connecting the adapter profile with the sash. For this purpose, the first leg can be arranged, for example, at a first end of the middle section.

Here, the first leg may be arranged on the central portion such that a substantially L-shaped or a T-shaped cross-section of the adapter profile results.

For example, a disc blocked in a conventional manner requires a peripheral frame which provides a stiffening and supportive function and must be dimensioned accordingly. In contrast, a rigid self-supporting unit is already provided by the firmly connected unit of adapter profile and disc, which can be firmly connected to the casement profile. In this way, the dimensioning of the casement profile is determined substantially less by a stiffening function than by the inclusion of the usual fittings for a window hardware. This has the consequence that the reduction of the dimensions of the sash profile is limited by the fittings used. The inner frame profile also provides for a receptacle of fittings and is therefore also determined essentially by this function in its dimensions.

In this way, the building interior side view surface of the sash profile and the frame profile can be reduced become. The building interior side view surface is the surface of the composite frame, which delimits the composite frame in the room-side direction and offers a view placed in the building as a view. The two frame profiles can consequently be designed significantly slimmer than in comparable conventional window frames and therefore allow for a given building opening a larger window area, since the frame portion of the window is reduced.

In contrast to conventional window frames with a blocked disc and a so-called Luftfalz a comparatively thin adhesive layer is applied in the fixed connection of the disc with the adapter profile, which reduces both the necessary space and is hardly perceived due to the small thickness in visible areas and therefore the aesthetic sensibility of a viewer not impaired. Furthermore, the rigid unit made of the disk and adapter profile made possible by the rigid connection allows immobile positioning of the disk in the composite frame. In contrast, with stronger vibrations of the sash, such as when slamming the sash, the disc can be moved in a position relative to the window frame in a conventional window frame with a blocked disc in position.

The frame profile and the sash profile fulfill, as shown above, essentially the function of receiving the usual fittings for a window or to connect the unit of disc and adapter profile with the fittings. Furthermore, both profiles form the building inside viewing surface of the composite frame and therefore must meet especially high aesthetic requirements.

For this purpose, the frame profile and the sash profile, for example, from a group consisting of wood, plastic, such as PVC, fiber reinforced plastic, such as glass fiber reinforced plastic (GRP) or carbon fiber reinforced plastic (CFRP), mineral materials or wood composite, such as Fibrex ™ from Anderson, to be selected. Also surface coatings of these materials on a frame profile made of a suitable material are conceivable.

Depending on the choice of materials for the frame profile and the sash profile when using the same material or when using uniform or uniformly appearing materials or surfaces, a uniform building inside appearance can be provided. However, the choice of materials is not limited to the choice of the same material for the frame profile and the sash profile, but it can also be different materials for the respective profiles are selected., However, which may not be consistent appearance of the inner surface or viewing surface can be achieved ,

According to a further embodiment, both the frame profile and the sash profile are made of wood and thus provided a slender frame with room-side uniform viewing surfaces.

The outer visible part essentially completely separates the composite frame from the building exterior side. The outer visible part is connected to the inner frame profile and has a building exterior surface, which is preferably accessible as the sole surface of the composite frame of the weather or this exposed. For this For example, the outer visible part extends over the adapter profile and adjoins the disc.

In this way, a uniform appearance of the composite frame is achieved with respect to the building exterior, since from the outside only the outer visible part or sections of the outer visible part and the disc are visible. In particular, in building facades with multiple windows or large-scale glass or window facades, which consist essentially of juxtaposed windows, such a uniform appearance is desired.

In addition to an openable composite frame, the design of a solid, non-openable composite frame (a so-called fixed field) is conceivable. Since the composite frame is completely covered by the outer visible part and is designed to be very slim, the openable composite frame and the fixed field have a comparable frame thickness, or can be made with the same or essentially the same frame thickness, without the composite frame of the fixed field becoming wider or narrower ., Has to be made substantially wider, as is the case in contrast to conventional window frames. In this way, there is no visible difference between an openable composite frame and a fixed field from the outside of the building. In particular, in building facades that have both openable windows as well as fixed fields, in this way a uniform building exterior appearance of the individual windows and possibly a uniform appearance of glass or window facades can be made possible.

For sealing the composite frame, a circumferential first seal, for example a seal with a sealing lip, may be arranged on the outer visible part on a rim of the outer visible part which is close to the pane. The first Seal can be arranged between the outer visible part and the disc such that in the closed state of the composite frame, the first seal or possibly the sealing lip structurally acts on the disc and / or the adapter profile. The first seal thus establishes a sealing connection between the pane and the outer visible part or between the adapter profile and the pane and in this way seals the outer visible part with respect to the pane or with respect to the adapter profile.

For receiving the seal on the outer visible part, for example, a groove can be provided on it, into which the seal is suitably inserted or fastened. For this purpose, for example, a groove may be provided on the section of the outer visible part which is closest to the pane, the opening of which points essentially in the direction of the building interior. Herein, a first seal can be fastened with a sealing lip, which structurally acts on the pane in the closed state of the composite frame. However, other common devices for mounting a seal on the outer visible part are conceivable.

In this way, the sealing lip resting on the disc together with the outer visible part forms a weather-side termination of the composite frame.

According to a further embodiment, the outer visible part may have a hollow cavity or may be formed as a hollow chamber profile. The cavity may be filled with air or a heat-insulating material from the group consisting of gases, insulating foam such as polyurethane foam, insulating wool or other suitable insulating insulating materials. In this way, the thermal conductivity of the outer viewing part can be additionally reduced become. The cavity is arranged, for example, in the connecting region to the window frame profile and reduces the heat conduction of the outer visible part, in particular to the room-side inner window frame profile. A formation of thermal bridges can thus be reduced or prevented.

Of course, versions with an outer visible part without Dämmkern or without cavity are possible.

The outer visible part may be made substantially of a material consisting of a group consisting of plastics such as PVC, fiber reinforced plastics, for example glass fiber reinforced plastic (GRP) and carbon fiber reinforced plastic (CFRP), mineral materials, wood composite such as Fibrex ^™ from Anderson, or a metal or a metal alloy, in particular aluminum or aluminum alloys is selected. However, other materials are conceivable that are suitable to withstand the stresses of the weather and are suitably moldable or executable. An outer visible part made of a fiberglass composite material is, for example, from the EP 0 586 213 A1 known.

According to a possible embodiment, the use of glass fiber reinforced plastic (GRP) for the production of the outer visible part is provided. In addition to high strength and weather resistance, GRP also provides comparatively low thermal conductivity, which can reduce the overall thermal conductivity of the frame in addition to providing a possible cavity with insulation. Furthermore, the already mentioned low thermal expansion of the fiber reinforced plastic allows a direct and easy connection with the adjacent inner frame profile. This fixed connection can, as already described, for example, by means of screwing and / or Bonding or other suitable connection. A decoupling of the outer visible part to account for different thermal expansions and to prevent thermal bridges between the example made of wood inner frame profile and the outer visible part made of GRP is not necessary. Furthermore, a formation of thermal bridges is prevented by means of the GRP, so that no decoupling is also provided to take account of this aspect.

Furthermore, the adapter profile can be designed according to an embodiment for attaching a second seal, which seals the adapter profile against a window frame surface of the composite frame. Conceivable for this purpose are the formation of a groove for receiving the second seal or other suitable devices.

In addition, the adapter profile may have a second leg which is disposed at a first end opposite the second end of the central portion.

For example, the second leg may be arranged at the middle portion such that the adapter profile has a substantially Z-shaped, U-shaped or H-shaped cross-section. The h-shaped cross section in this case represents a combination of the Z-shaped and the U-shaped cross section.

The second leg closes according to said cross-sections of the building exterior side surface of the disc. The angled cross-sections stiffen the adapter profile and allow the provision of the rigid, self-supporting unit of adapter profile and disc.

Of course, various variations of the cross sections shown or differently shaped cross sections for the adapter profile are possible.

The first leg is connected to the inner sash profile, for example. According to the illustrated cross-sectional shapes, the first leg extends substantially in a plane parallel to the room-side disk surface. The first leg thus has a building inside surface, by means of which the adapter profile can be connected to the inner sash profile. This can, as described above, also be done by means of screwing and / or gluing or in another suitable manner.

The connection of the adapter profile with the inner sash profile can be carried out such that the disc is not in contact with the inner sash profile, but spaced from this and a joint between the two elements is formed. In this gap, for example, a suitable insulating material may be arranged to isolate the sash profile relative to the disc.

According to a possible embodiment, the adapter profile is made of a material which has only a very low thermal expansion or a thermal expansion substantially corresponding to the disc, so that a firm or rigid and substantially peripheral connection of the adapter profile with the disc without the occurrence of Tension in or between the individual elements is made possible. By means of a high-strength and stiff material, it is also possible to form various thin-walled cross-sections for the adapter profile.

The adapter profile is therefore preferably made of a material that can be selected from a group comprising fiber reinforced plastics such as glass fiber reinforced plastic (GRP) and carbon fiber reinforced plastic (CFRP). In addition to a high strength, these materials meet the property of low thermal expansion coefficient or an expansion coefficient of the thermal expansion of a glass pane comes close.

The proposed for attaching a second seal groove near the first leg, for example, from the first leg and an extension which is arranged parallel to the first leg on the adapter profile, are formed. The opening direction of the groove thus runs parallel to the orientation of the first leg. Alternatively, the groove on the first leg may be in another suitable one as well Way executed and / or be aligned in another direction so that it can seal the adapter profile against a frame surface of the composite frame.

In this groove, a second seal, for example a seal with a sealing lip, can be suitably fastened. The second seal or possibly the sealing lip thereof extends up to the obvious outer visible part and structurally acts on a surface of the outer visible part arranged within the composite frame and in this way seals the adapter profile against the outer visible part. The arrangement of the second seal between the adapter profile and the outer visible part thus counteracts the formation of thermal bridges.

According to another possible embodiment, both the outer visible part and the adapter profile are made of glass fiber reinforced plastic. With this embodiment, a very low thermal conductivity is achieved, which significantly reduces or prevents the formation of any thermal bridges by the arrangement of the second seal between the adapter profile and the outer visible part.

According to a further embodiment, an inner side surface of the sash frame profile and an edge surface of the outer visible part and / or an edge surface of the first seal are arranged substantially in a common plane so that a common surface extending through the disk or appearing to extend through the disk Frame is illustrated. Here, the inner side surface of the sash profile represents the adjacent to the disc surface of the sash profile.

This means that essentially no step is perceptible between the two surfaces, so that a viewer sees an apparently continuous surface, which is interrupted only by the pane and thus, in particular, aesthetic aspects can be taken into account. A stage configuration and possible protrusions of the adapter profile or sash profile projecting from this seemingly continuous surface into the transparent area of the pane can be avoided in this way, ie. It is prevented that the first seal and / or the sash profile protrude significantly into the transparent region of the disc and are visible from the respective opposite side. This is usually the case in particular when applied to the disc seals and is usually perceived by a viewer as not aesthetically.

According to a further embodiment, the above-described arrangement of the side surface of the sash profile and the edge surface of the outer visible part can be achieved, that the respective building inside and weather side viewing surface of the composite frame are formed substantially the same size. This means that the building exterior side surface of the outer visible part, possibly with a protruding seal or a sealing lip, is the same size as in the direction of the building inside (in the case of closed composite frame) provided viewing surfaces of the sash profile frame and the frame profile together. In a cross section through the composite frame, this corresponds to a same height of the outer visible part including an optionally attached first seal and the sash profile frame together with the adjacent frame profile.

With the invention, a weather-protected frame profile for windows or doors is provided according to an embodiment, the room side, for example, consists of wood and thus meets high demands on the building design. Due to the stiffening, load-bearing design of the Flügelholzrahmens by the outside patch and permanently connected to the Flügelholzrahmen circumferential window profile, for example, fiberglass, the design of a frame with very small view width (slim frame) is possible, so that modern design claims can be satisfied. Due to the exemplary use of glass fiber reinforced plastic for the window profile and the outer visible part of the heat transfer coefficient of the composite frame is improved compared to a wood-aluminum window. Due to the low thermal conductivity of the GRP, no thermal bridges occur in the frame cross-section.

As a further embodiment, a direct connection of the window fittings with the adapter profile is conceivable. In this way, for example, waives a use of at least the sash profile and so the frame can be made even slimmer. Of course, the adapter profile does not enclose the disc completely or substantially circumferentially. Rather, the adapter profile may also include the disc partially only in any number of sections or be connected to the disc, such as in the field of load transfer on the window fittings. This means that the substantially circumferential adapter profile can have any number of interruptions. Similarly, the fitting of fittings is comparable to a frameless glass door conceivable in which the fittings are spaced from the edge of the disc are mounted, with no use of the edge of the disc (partially) comprising Adapter profile is necessary. Of course, in any case, provide a suitable seal the disc, with a person skilled in the field of window and door construction suitable designs of a seal assembly are familiar.

According to a further embodiment, it is conceivable to use an adapter profile with a pane without a frame. In this case, the disk is substantially circumferentially or in any number of sections partially connected to the adapter profile, which may be directly or indirectly connected to the building.

Further advantages and embodiments of the invention will become apparent from the description, the dependent claims and the accompanying drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.

FIG. 1 shows a first embodiment of a composite frame 110 according to the invention. The composite frame according to the invention is suitable for insertion into a building opening, in particular a window or door opening. The installation can be vertically vertical, but also inclined (eg as a roof window). Of course, oriented in another spatial direction installation such as a substantially horizontal installation is conceivable.

The composite frame according to the invention comprises a frame 112 facing the building exterior and a sash frame 114 hinged to the frame 112. Usually, the sash frame 114 is hinged to the frame 112 by means of hinges such that it can be pivoted open in the horizontal direction. In many cases, the hinge mechanism for the articulation of the casement 114 on the frame 112 is designed so that the casement with respect to the frame beyond also in an inclined inclination (angle of inclination to the vertical) can be opened. Of course, the sash can also be configured as a "sash" or fixed (non-openable) frame without departing from the scope of the invention.

According to the invention, the casement 114 comprises a casement profile 116 on which an adapter profile 118 is attached in the direction of the exterior of the building (that is, on an outwardly facing side of the casement profile 116). The adapter profile 118 is according to the illustrated embodiment, for example, glass fiber reinforced plastic and is firmly connected to the sash profile 116. In the example of the representations in the FIGS. 1 to 4 the fixed connection is realized by means of screws 117. Alternatively, the solid connection can also be realized by means of gluing or by screwing and gluing. Also, any other familiar to the window maker way of solid connection between the according to the dargstellten embodiment of wooden casement profile and the adapter profile made of glass fiber reinforced plastic can be used.

The adapter profile 118 has a substantially Z-shaped cross-section with a first 118a and a second 118c leg and a central portion 118b connecting the two legs 118a, 188c. In this case, the first 118a and the second 118c legs are each angled substantially at right angles to the central portion 118b, the second leg 118c and the central portion 118b fixed to the disc 120 and a heat-insulating edge assembly 121 of the disc and a weather-side surface 120a of the disc 120th are connected. The first leg 118a is connected to the inner wing frame profile 116.

The substantially Z-shaped cross section of the adapter profile 118 has a projection arranged parallel to the first leg 118a and a groove 118d formed between the first leg and the extension for receiving a second seal 132 with a sealing lip. The opening of the groove 118d is aligned parallel to the first leg 118a in the illustrated embodiment. Structurally, the sealing lip acts on a surface 124b of the outer visible part 124 arranged within the composite frame 110 and seals the adapter profile 118 against the outer visible part 124.

The frame 112 is also formed substantially in two parts and comprises a frame profile 122 which rotates about the sash profile 116 of the sash 114 substantially. In addition, the frame 112 comprises an outer visible part 124, which according to the invention according to the illustrated embodiment of glass fiber reinforced plastic (or of a substantially glass fiber reinforced plastic containing composite material) consists. The outer visible part 124 made of glass-fiber reinforced plastic (GRP) facing the outside of the building is fixedly connected to the window frame 122. As in the case of the casement 114 and as shown by way of example in FIGS. 1 to 4, the fixed connection can take place by means of screws 123 or by gluing or by means of gluing / screwing or any other connection method suitable in window construction.

The outer visible portion 124 is formed to substantially completely demarcate the composite frame 110 on the building exterior side and to abut the disc 120 so that substantially only a building exterior surface 124a of the outer viewing portion 124 is exposed to weather as the sole surface of the composite frame is.

For receiving a first seal 130 with a sealing lip, a groove 124d is provided on the portion of the outer visible part which is closest to the disc, into which the first seal 130 is inserted. The opening of the groove 124d points substantially in the direction of the building interior. The sealing lip acts structurally in the illustrated closed state of the composite frame 110, the disc 120 and seals the outer visible part 124 against the disc 120 from. The resting on the disc 120 sealing lip 124d together with the outer visible part 124 thus forms the weather-side termination of the composite frame 110.

To complete the composite frame 110 according to the invention prior to installation in the intended building opening a disc 120 is inserted into the adapter profile 118 made of GRP and firmly connected to this, eg. By circumferential bonding to all four edges of the disc 120th Of course, other disc shapes such For example, round or polygonal shapes possible. The pane 120 is in particular an insulating glass pane. The disk 120 may be made of glass or other suitable material. About the fixed connection with the adapter profile 118, in particular bonding, the disc 120 is used to stiffen the sash assembly 114, so that a rigid and self-supporting unit is formed. Due to the rigid and thus load-bearing connection of the adapter profile 118 with the casement profile 116, the casement profile 116 is stiffened by the disc 120. As in the presentation of FIGS. 1 to 4 by way of example, the insulating glass pane 120 has a heat-insulating edge composite 121 (for example made of plastic (PVC) or another suitable material). As an alternative to a heat-insulating edge bond, it goes without saying that a conventional edge seal is also possible. Of course, versions with insulating glass with more than one chamber are possible.

The fixed frame portion of the composite frame according to the invention is, as already explained above, formed by the frame 112, which consists of the inner frame profile 122 and the outer visible portion 124. The frame 112 and the wing frame 114 meet in the illustrated embodiment in the closed state at three sealing levels on each other, namely an outer seal 130 between the outer viewing part 124 and the disc 120, a middle seal 132 between the outer viewing part 124 and the window profile 118 and an inner seal 134 between the sash profile 116 and the frame profile 122. The representation with three sealing planes is exemplary; the window manufacturer knows that at least one sealing plane is to be provided between the two frame sections which are movable relative to each other (primarily the middle sealing plane here) and furthermore that any number of sealing planes (two, three, four or even more) is conceivable.

The outer visible portion 124 of the frame 112 is designed as a hollow profile with a cavity 135 which can be provided with an insulating core to improve the heat transfer coefficient of the composite frame.

An inner side surface 116a of the sash frame profile 116 and an edge surface 124c of the outer gland 130 border at substantially the same height (indicated by the line A-A) flush with each other, thereby forming a frame apparently extending through the disc 120.

The aspect of extending through the disc frame is achieved in the illustrated embodiment by a suitable design of the outer viewing part 124 and the seal 130 and the sash profile 116 and the frame profile 122, which is characterized by equally large free viewing surfaces both room inside and building outside (shown through the building exterior side height of the composite frame h1 and the room-side height h2).

According to one in FIG. 5 In addition, an inner surface 120d of the edge composite of the disk is also arranged substantially at or slightly below the height AA. In this way, results in an extending through the disc, seemingly continuous surface.

Furthermore, in FIG. 1 the disc 120 by means of the adapter profile 118 in the illustrated embodiment spaced from the inner sash profile and provided a joint between the two elements. This joint is closed by means of an insulation 136 at least at the upper edge of the joint. Of course, the insulation can also fill the joint completely.

The FIGS. 2 to 4 and 7 show further embodiments of composite frame according to the invention, and the Figures 5 and 6 show a perspective sectional view of the composite frame of FIG. 1 in closed or opened state. The three-digit reference numbers indicate the number of the figure in their first place, and two-digit identical number sequences following the first number indicate identical or similar elements in the respective figures.

FIG. 5 shows one of the FIG. 1 comparable inventive composite frame 510 in a perspective sectional view, and FIG. 6 shows the composite frame of the FIG. 5 in a perspective sectional view in the open state.

FIG. 2 shows an embodiment of the FIG. 1 similar composite frame 210 with a frame 212 and a sash 214, which meet at a total of three sealing levels 230, 232, 234 in the closed state.

The main difference between the composite frame 210 of the FIG. 2 and the composite frame 110 of FIG. 1 is that the frame profile 222 of the FIG. 2 in from the embodiment of FIG. 1 deviating manner is attached to a projecting from the outer visible part 224 to the building inside profile section 225.

FIG. 3 shows a horizontal section through a composite frame 310 according to the invention, which integrates two adjacent windows. The horizontal section of the FIG. 3 shows a post 326 of the frame 312 (as part of the outer viewing part 324). The composite frame of the FIG. 3 comprises a first wing frame 314.1 (in the illustration of Figure 3, left) and an adjacent second wing frame 314.2 with corresponding discs 320.1, 320.2. Each of the sash frames 314.1, 314.2 according to the invention consists of a sash profile 316.1, 316.2 and an adapter profile 318.1, 318.2 firmly connected to the sash frame profile 316.1, 316.2.

The frame 312 of the composite frame 310 of FIG. 3 has a frame profile 322 fixedly connected to the outer visible part 324, which essentially revolves around the casement profile 316.1, 316.2 and forms a post in the region between the two casement profiles 316.1, 316.2 (sectional view of FIGS FIG. 3 ). The fixed connection between the frame profile 322 and the outer visible part 324 takes place, for example, by screwing 323. Figuratively speaking, the frame arrangement of FIG. 3 is a mirror-image duplication of the single frame FIG. 1 , with in the FIG. 3 A axis designated as a mirror axis.

FIG. 4 shows a horizontal section through a further embodiment of a composite frame according to the invention.

The in FIG. 4 shown composite frame 410 is designed to accommodate two adjacent windows that adjoin one another via a forend 425 of the outer viewing portion 424 of the frame 412. In the embodiment of FIG. 4 is just one of the two windows (in the representation of the FIG. 4 left arranged window) with the casement 414.1 openable, while the right next window has a fixed to the frame 412 connected "sash" 414.2 and thus fixed and not openable (such an arrangement is, for example, in the door area usual, with an openable glass door and an adjacent fixed window). Of course, the "fixed wing frame" 414.2 of the embodiment of the FIG. 4 be designed also openable; this would mean that it can only be opened when the left wing frame 414.1, which overlaps the building inside, is already open.

Of the embodiment of FIG. 3 the composite frame 410 differs from the FIG. 4 insofar as the frame profile is formed circumferentially around both sash profiles 416.1, 416.2 and in the cutout view of FIG. 4 is therefore not visible, since in the area of the forend 425, where the two sash profiles 416.1, 416.2 meet, no frame profile is provided. In other words, it could also be said that in the area of the forend 425 the "fixed sash profile" 416.2 assumes the function of the frame profile, since in the illustrated embodiment it is firmly connected to the outer visible part 424. (However, this approach is no longer applicable in the case of an openable right sash 414.2.)

FIG. 7 shows one of the FIG. 1 essentially comparable cross section of a further embodiment of a Composite frame according to the invention with a frame extending through the disc.

For this purpose, in addition to the inner side surface 116a of the casement profile 116, the edge surface 124c of the outer visible part or the seal 730 arranged there is also arranged at the height A-A. The surfaces lie substantially in a common plane or at the same height (A-A) and result in a common surface extending through the disk or a frame apparently extending through the disk. An arrangement of the inner surface 720d of the edge composite of the disc essentially in this plane or slightly below the plane further enhances the resulting impression.

In contrast to FIG. 1 The outer visible part 124 additionally surrounds the inner window frame profile and has a stabilizing or stiffening recess 740 of the cavity 735. The shape of the first seal 730 also differs from the in FIG. 1 illustrated seal 130. A match of heights h ₁ and h ₂ off FIG. 1 However, due to the structural differences, it is no longer possible.

FIG. 8 shows a horizontal section through a further embodiment of a composite frame according to the invention with an openable window and an adjacent fixed field window, wherein the section passes through a so-called post area. In the embodiment of FIG. 8 is just one of the two windows (in the representation of the FIG. 8 left-hand window 820.1) with a casement 814.1 openable, while the right adjacent window 820.2 is firmly connected to the frame 812 and thus fixed and not openable. The post area continues in the illustrated Embodiment of the outer visible part 824 and the frame profile 822 of the openable window together. The outer visible part 824 and the frame profile 822 provide an additional receptacle for the adjacent fixed field window 820.2 in the illustrated post area. The in FIG. 8 shown composite frame 810 is thus designed to accommodate two adjacent windows, which adjoin the outer visible part 824 of the frame 812. For fixed connection of the fixed field window 820.2 with the frame 812, the disc 820.2 is clamped between a pressure seal 841 and a portion of the outer viewing part 824 in the illustrated embodiment. Of course, the fixed field window 820.2 can also be carried out as an openable window sash. In this case, the frame 822 and the outer visible part 824 (in the illustrated area) are designed as a forend.

The main differences of FIG. 8 across from FIG. 4 consist in an alternative embodiment of the outer viewing part 824 and the fixed connection of the fixed field window with the frame without the use of an adapter profile for the fixed field window. Of course, the disc of the fixed field can also be mounted by means of an adapter profile on the frame.

FIG. 9 shows one of the FIG. 1 similar cross section / vertical section through a further embodiment of a window with a composite frame 910 according to the invention in the installed state. FIG. 9 differs from FIG. 1 essentially in the attachment of the outer visible part 924 on the frame profile 922 by means of a screw 923 (indicated by dashed lines). The screws used for this extend in contrast to FIG. 1 through a portion of the outer viewing part 924 to the frame profile 922. As an entry point into the outer visible part 924, in the illustrated embodiment, the indentation 940 is used in the outer, visible part 924. Other significant differences over the FIG. 1 represent the further embodiments of the first seal 930 and the insulation 936.

FIG. 10 shows one of the FIG. 4 similar horizontal section through a further embodiment of a composite frame 1010 according to the invention with two adjacent windows 1020.1, 1020.2, wherein the section through the forend area 1025 extends. FIG. 10 provides another embodiment of the outer viewing part 1024 for use with two side-by-side windows. Furthermore, the first seals 1030.1, 1030.2 are designed according to a further embodiment. The outer visible part engages in the illustrated embodiment in the adapter profile 1018.2. For this purpose, a defined distance (for example 0.2 mm) is provided between the adapter profile 1018 and the outer visible part 1024 at the points 1060.

FIG. 11 shows one of the FIG. 3 similar horizontal section through a two juxtaposed window integrating composite frame 1110 according to the invention in the post area. FIG. 11 provides another embodiment of the outer panel 1124 for use with two side-by-side windows. Furthermore, the first seals 1130.1, 1130.2 are designed according to a further embodiment.

FIG. 12 shows one of the FIG. 9 similar cross section / vertical section through a further embodiment of a window with a composite frame according to the invention 1210 and an insulating glass pane 1220th

FIG. 13 shows one of the FIG. 12 similar cross section / vertical section through a further embodiment of a window with a composite frame 1310 according to the invention and an insulating glass pane 1320. The illustrated insulating glass pane has on the building exterior side surface an additional insulating layer or one compared to FIG. 12 greater glass thickness of the disc.

FIG. 14 shows one of the FIG. 13 similar cross-section / vertical section through a further embodiment of a window with a composite frame according to the invention 1410 and an insulating glass 1420. The illustrated insulating glass 1420 has on the building exterior side surface an additional insulating layer or one compared to FIG. 13 greater glass thickness of the disc.

FIG. 15 shows one of the FIG. 12 similar cross-section / vertical section through a further embodiment of a window with a composite frame according to the invention 1510 and an insulating glass pane with two chambers 1520.1, 1520.2. The insulating glass pane has a greater glass thickness of the pane in comparison to the figures described above. To accommodate the disc, the adapter profile 1518 is adapted according to its extent in the illustrated embodiment and the casement profile 1516 executed with a suitable recess.

The invention thus opens the possibility for the construction of windows with very slim, weather-protected frame profiles with a high frame insulation effect. Due to the fixed connection between the disc 120, adapter profile 118 and casement profile 116, the face width of the composite frame in comparison to conventional Window constructions are reduced, so that a narrower frame width can be achieved. The design of the outer part of the frame 112 protects the inside wood elements (sash profile and frame profile) from the weather. The use of GRP for the adapter profile 118 and the outer visible portion 124 of the frame 112, the heat transfer coefficient of the frame is significantly improved compared to conventional wood-aluminum windows. In particular, due to the low thermal conductivity of the GRP no heat bridges in the frame cross-section.
