Description

Composite frame for insertion into a building opening

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.

EP 0 586 213 A1 discloses a composite material consisting of polymer and wood fibers which can be extruded into a window frame. In contrast, the invention proposes a composite frame and an adapter profile for a window or a door with a very small frame cross-section, ie with a small face width of the frame.

The composite frame according to the invention has a (in the installed state) fixed first frame portion. At this first frame section, a second, revealable frame section is articulated. The apparent second frame portion, 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 apparent 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 apparent second frame section is referred to as a sash frame. These terms are used below. Correspondingly, the profile of the frame arranged inside the building is referred to as the inner frame profile and the profile of the sash frame arranged inside the building is referred to as the inner sash frame profile. The disk and the adapter profile can be connected to each other substantially circumferentially 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 visible part with the inner window frame profile can also take place, for example, by gluing and / or by screwing. However, other suitable forms of attachment are possible.

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 casement profile and the frame profile can be reduced. be graced. 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 selection 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, which, however, may not be achieved a uniform appearance of the inner surface or viewing area.

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 apparent composite frame, the execution of a fixed, not revealed composite frame (a so-called fixed field) is conceivable. Since the composite frame is completely covered by the outer visible part and is made very slender, the apparent composite frame and the fixed field have a comparable frame thickness, or can be made with a same or substantially the same frame thickness, without the composite frame of the fixed field must be made wider or substantially wider, as is the case in contrast with conventional window frames. In this way, there is no difference visible from the outside of the building between an open composite frame and a fixed field. In particular, in building facades, which have both open windows and fixed fields, in this way a uniform building exterior appearance of the individual windows and possibly a uniform appearance of Glasbzw. Window facades are 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 closest to the disc, 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 forms, together with the outer visible part, 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 connection 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 view part without insulating core or without a cavity are also 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 GFRP composite material is known, for example, from EP 0 586 213 A1.

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 take into account different thermal expansions and to prevent thermal bridges between the example made of wood inner frame profile and the outer blinding part made of fiberglass 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.

The proposed adapter profile, which can be used for example in a composite frame as described above, is provided for fixed connection to a disk and for fixed connection to a sash profile.

For this purpose, a cross-section of the adapter profile according to a possible embodiment comprises a middle section for connecting the adapter profile to the pane and at least one first leg for connecting the adapter profile to the casement. For this purpose, the first leg can be arranged, for example, at a first end of the middle section.

In this case, the first leg may be arranged on the middle section such that a substantially L-shaped or a T-shaped cross section of the adapter profile results.

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 on the middle section 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 in another ge¬

ll suitably executed and / or be aligned in another direction, so that they 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, if appropriate, sealing lip extends up to the proximal outer 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 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 design and possible projecting from this seemingly continuous surface protrusions of the adapter profile or the sash profile in the transparent region of the disc can be avoided in this way, ie it prevents the first seal and / or the sash profile clearly in the transparent region of the Protruding disk and are visible from the 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 casement frame profile and the edge surface of the outer visible part can be achieved in that the respective building innenssei- 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 (with 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 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. Likewise, the fitting of fittings is comparable to a frameless glass door conceivable in which the fittings are spaced from the edge attached to the disc, with no use of the edge of the disc (partially) encompassed send 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.

The invention is illustrated schematically by means of embodiments in the drawing and will be described in detail below with reference to the drawing.

FIG. 1 shows a first exemplary 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 may also be configured as a "sash" or fixed (not disclosed) 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 consists according to the illustrated embodiment, for example, glass fiber reinforced plastic and is fixed to the sash profile 116 Ver. prevented. In the example of the illustrations in 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 middle 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 in FIGS. 1 to 4, the fixed connection can be exemplified by means of screws 123 or by means of adhesive bonding or by means of gluing or screwing. or any other connection method suitable in window construction.

The outer visible part 124 is designed such that it substantially delimits the composite frame 110 completely on the building exterior side and adjacent to the pane 120, so that essentially only one building exterior side surface 124a of the outer viewing part 124 is accessible to the weather surface as the sole surface of the composite frame or is exposed to this.

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 closure 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 shown by way of example in the representation of FIGS. 1 to 4, 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 sash 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 wing frame 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 line A-A) flush with each other, thereby forming a frame apparently extending through the disc 120 becomes.

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 hl and the room-side height h2). According to an embodiment shown in FIG. 5, in addition, an inner surface 12Od 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 Figure 1, the disc 120 is spaced from the inner sash profile by means of the adapter profile 118 in the illustrated embodiment and a gap is provided 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.

Figures 2 to 4 and 7 show further embodiments of composite frame according to the invention, and Figures 5 and 6 show a perspective sectional view of the composite frame of Figure 1 in the 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 a composite frame 510 according to the invention which is comparable to FIG. 1 in a perspective sectional view, and FIG. 6 shows the composite frame of FIG. 5 in a perspective sectional view in the opened state.

FIG. 2 shows a composite frame 210 similar to the exemplary embodiment of FIG. 1 with a frame 212 and a sash frame 214, which meet at a total of three sealing levels 230, 232, 234 in the closed state. The essential difference between the composite frame 210 of FIG. 2 and the composite frame 110 of FIG. 1 is that the frame profile 222 of FIG. 2 differs from the embodiment of FIG. 1 in a profile section 225 projecting from the outer visible part 224 to the inside of the building is attached.

FIG. 3 shows a horizontal section through a composite frame 310 according to the invention, which integrates two adjacent windows. The horizontal section of Figure 3 shows a post 326 of the frame 312 (as part of the outer viewing part 324). The composite frame of Figure 3 comprises a first wing frame 314.1 (in the illustration of Figure 3 on the 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 which is fixedly connected to the outer visible part 324 and essentially revolves around the sash profile 316.1, 316.2 and forms a post in the area between the two sash profiles 316.1, 316.2 (sectional view of FIG. , By way of example, the frame arrangement of FIG. 3 is a mirror-image duplication of the single frame of FIG. 1, with the axis labeled A in FIG. 3 as the mirror axis.

FIG. 4 shows a horizontal section through a further exemplary embodiment of a composite frame according to the invention. The composite frame 410 shown in FIG. 4 is designed to receive two adjacent windows, which adjoin one another via a fold 425 of the outer viewing section 424 of the window frame 412. In the embodiment of Figure 4 is only one of the two windows (the left in the illustration of Figure 4 arranged window) with the sash 414.1 apparently, while the right next window has a fixed to the frame 412 connected "sash" 414.2 and thus is fixed and not apparent (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 Figure 4 may also be designed apparently; This would mean that it is only then apparent when the building inside cross-left frame 414.1 is already open.

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

FIG. 7 shows a cross section of a further exemplary embodiment of a substantially comparable cross section of FIG 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 view 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 72Od of the edge assembly of the disc substantially 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 seal 130 shown in FIG. However, a match of the heights hi and h ₂ of Figure 1 is no longer possible due to the structural differences.

FIG. 8 shows a horizontal section through a further exemplary embodiment of a composite frame according to the invention with an openable window and an adjacent fixed field window, the section extending through a so-called post area. In the embodiment of FIG. 8, only one of the two windows (the window 820.1 on the left in FIG. 8) with a casement 814.1 is apparent, while the window 820.2 on the right is fixedly connected to the casement 812 and thus fixed and not apparently. The post area continues in the illustrated Embodiment of the outer visible part 824 and the frame profile 822 of the reveal 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 composite frame 810 shown in FIG. 8 is thus designed to accommodate two adjacent windows, which adjoin one another via 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 performed as an open window sash. In this case, the window frame 822 and the outer visible part 824 (in the illustrated area) are designed as an insert.

The essential differences of Figure 8 over Figure 4 consist in an alternative embodiment of the outer visible 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 a cross section / vertical section similar to FIG. 1 through a further exemplary 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 to the frame profile 922 by means of a screw connection 923 (indicated by dashed lines). In contrast to FIG. 1, the screws used for this purpose extend through a subregion of the outer visible part 924 as far as into the frame profile 922. As an entry point into the outer frame In the illustrated embodiment, the recess 940 is used in the outer visible part 924. Further essential differences with respect to FIG. 1 represent the further embodiments of the first seal 930 and the insulation 936.

FIG. 10 shows a horizontal section similar to FIG. 4 through a further exemplary embodiment of a composite frame 1010 according to the invention with two adjacent windows 1020.1, 1020.2, the section extending through the forend area 1025. Figure 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 a horizontal section similar to FIG. 3 through a composite frame 1110 according to the invention which is integrated in the post area and incorporates two juxtaposed windows. Figure 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 a cross section / vertical section similar to FIG. 9 through a further exemplary embodiment of a window with a composite frame 1210 according to the invention and an insulating glass pane 1220. FIG. 13 shows a cross-section / vertical section similar to FIG. 12 through a further exemplary 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 an additional insulating layer on the building exterior side surface or a comparison with FIG greater glass thickness of the disc.

FIG. 14 shows a cross section / vertical section similar to FIG. 13 through a further exemplary embodiment of a window with a composite frame 1410 according to the invention and an insulating glass pane 1420. The illustrated insulating glass pane 1420 has an additional insulating layer on the building exterior side surface or a larger one in comparison with FIG Glass thickness of the disk.

FIG. 15 shows a cross section / vertical section similar to FIG. 12 through a further exemplary embodiment of a window with a composite frame 1510 according to the invention 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 occur in the frame cross-section.
