The invention concerns a window frame system for fixing at least a first panel comprising at least two plates which extend parallel to each other. The window frame system comprises at least a first window frame structure which comprises at least a first window frame profile and a first thermally insulating element. The invention furthermore concerns a thermally insulating element for use in the window frame system according to the invention. In addition, the invention concerns a method for implementing aspects of the window frame system according to the invention, a flexible profile for sealing openings between the at least first panel and the first window frame structure of the window frame system according to the invention, a control system for use in the window frame system according to the invention, and a sun protection system for use in the window frame system according to the invention.
Window frame systems known from the prior art comprise usually tubular window frame profiles with large dimensions necessary for the installation of connecting elements which are used to connect the window frame profiles together in order to assemble the window frame system. For given dimensions of a recess in a wall, for example for a window, after installation of the window frame system, due to the relatively wide window frame profiles which for example comprise aluminium, a relatively small area remains for the passage of light through the window. Due to the relatively large dimensions of the window frame profiles, the window frame profiles are clearly visible. An insulating panel supported by the window frame profiles, for example an insulating glass panel, has a better thermal insulation value than the window frame profiles. Due to the relatively wide window frame profiles, the thermal insulation value of the window frame is relatively limited.
It is an object of the invention to produce a window frame system which eliminates or at least reduces the above-mentioned disadvantages of window frame systems known from the prior art. Furthermore, the invention concerns the provision of a window frame system with the smallest possible dimensions and an improved insulation value of the total window frame system. This leads to a window frame system which uses as little material as possible, allows as much light as possible to pass to the inside through the window and door frame, and allows the use of more glass and/or more wall space which gives a better thermal insulation value. The total thermal insulation of a window frame-glass-wall combination is better if the proportion of the most poorly insulating part, the window frame, is reduced.
At least one of these objects is achieved by a window frame system according to the invention, wherein the window frame system comprises at least a first window frame structure, wherein the first window frame structure comprises at least a first window frame profile which is provided with at least a first holder and a second holder; at least a first thermally insulating element which comprises at least a first end and a second end, wherein the first end can be received in the first holder of the at least first window frame profile, wherein the at least first thermally insulating element is provided with at least one of a sixth holder and a seventh holder, wherein the sixth holder is oriented towards the second end and the seventh holder is oriented towards the first end; at least a first flexible profile which comprises a first sealing element which can be coupled to at least the first window frame profile and a first plate of a first panel which can be received in the window frame system; at least a first glass lath which can be coupled to a second plate of the first panel and the at least first thermally insulating element; wherein the second holder of the at least first window frame profile and the sixth holder and/or the seventh holder of the at least first thermally insulating element comprise at least one internal corner with a radius which is smaller than 0.5 mm. By using holders with internal corners which have a radius smaller than 0.5 mm, there is no need to take account of minimum dimensions required for surface treatment. In the window frame system according to the invention, this is achieved by using the holders in the system only where no surface treatment is necessary. In this way, the dimensions of the window frame profile may be smaller than in window frame profiles already known. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.
In an embodiment of the window frame system according to the invention, the first flexible profile furthermore comprises at least a first coupling element and a second coupling element, wherein the first coupling element can be received in the second holder of the at least first window frame profile, and the second coupling element can be received in the sixth holder of the at least first thermally insulating element.
In an embodiment of the window frame system according to the invention, the at least first glass lath comprises at least a third coupling element which can be received in the seventh holder of the at least first thermally insulating element. The abovementioned embodiments of the window frame system according to the invention concern the provision of an insulated window frame profile/window frame structure with holder for glass laths and/or glazing rubbers/first flexible profile, wherein the holders are integrated in the isolator/thermally insulating element. In this way, the depth of the isolator is not limited to the location of the holder of the glass lath or the rubber in the shell part which does not give good insulation. Therefore the isolator can allow the omission of a shell part, for example the second shell part. The window frame profile may thus consist of only two shell parts, namely the first (metal, e.g. aluminium) window frame profile and the thermally insulating element, instead of three, namely the first (metal, e.g. aluminium) window frame profile, the second (metal, e.g. aluminium) window frame profile and the thermally insulating element which connects the first and second window frame profiles together. Because the isolator is deeper, the insulation value of the profile/window frame structure is improved and hence also the insulation value of the total window frame.
In an embodiment of the window frame system according to the invention, the window frame system furthermore comprises a second window frame profile which is provided with at least a fourth holder, wherein the second end of the at least first thermally insulating element can be received in the fourth holder for connecting together at least the first window frame profile and the second window frame profile. In this way a window frame structure can be obtained comprising two metal, e.g. aluminium, window frame profiles that are connected together via a thermally insulating element.

The abovementioned connection ways have the advantage that in this way, the dimensions of the isolator and the holders of the half-shells and hence the window frame profile may be smaller than in window frame profiles already known. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.

Therefore the isolator can allow the omission of a shell part, for example the second shell part. The window frame profile may thus consist of only two shell parts, namely the first (metal, e.g. aluminium) window frame profile and the thermally insulating element, instead of three, namely the first (metal, e.g. aluminium) window frame profile, the second (metal, e.g. aluminium) window frame profile and the thermally insulating element which connects the first and second window frame profiles together.

Although the invention will be described with reference to specific embodiments which are depicted diagrammatically in the enclosed figures, the invention is not restricted to the embodiments shown.

Although the enclosed figures show explicit combinations of measures according to the invention, it will be evident to the person skilled in the art that a number of these measures may also be taken separately from each other.
The figures are not necessarily drawn to scale. Identical or similar components may be indicated with the same references in the different figures.
It will be evident to the person skilled in the art that the different aspects of the invention as described with reference to the enclosed figures may be used advantageously separately, but that these aspects may also be combined in any arbitrary advantageous manner.

The different aspects of the invention are aimed at producing window frame systems 1, such as window and door frames, with the smallest possible dimensions, at least in directions transverse to the longitudinal direction of the window frame structures from which the window frame system is constructed. A window frame system 1 according to the invention for a window or a door is for example constructed from four window frame structures which extend in pairs at right angles to each other, wherein ends of the window frame structures lying next to each other are connected together, preferably by means of a weld connection. This gives a window frame system 1 according to the invention wherein as little material as possible is used, as much light as possible can penetrate to the inside through the window and door frame, and more glass and/or more wall may be used which gives a better thermal insulation. The total thermal insulation of a window frame-glass-wall combination is better if the proportion of the most poorly insulating part, the window frame, is reduced.
Before discussing the above-mentioned figures in detail, a number of aspects of the invention will first be discussed.
Insulated Window Frame System Without Holders for Fittings and/or Profile-Widening Holders for Glass Laths
This aspect of the invention relates to profiles of insulated window frame systems (steel, aluminium, plastic or wood). Insulated window frame systems (not steel) have specific holders for various components which are not assembled with or connected to the profiles, which make the profiles wider and hence reduce the insulation value of the total window frame system. By omitting these protruding holders from the system, the width of the profiles (insulated aluminium, plastic, composite, bio-composite, rubber) can be minimised, whereby the insulation value of the window frame can be improved.
This aspect of the invention relates to the holder of the glass laths of insulated window frame systems (steel, aluminium etc.). Such window frame systems are suitable for windows or doors. For fixing panels or glazing in the window frame system, glass laths are attached to the second window frame profile after the panel or glazing has been placed in the window frame. These glass laths are fixed, in specific recesses/holders, to a shell part, the second window frame profile, of the assembled profile/window frame structure. However, by fixing these glass laths to a shell part, the second window frame profile, of the insulated profile/window frame structure, the depth of the isolator/thermally insulating element is limited to the location of the glass lath in the holder of the shell part. The depth of the isolator, i.e. the extension of the thermally insulating element in a direction perpendicular to the plates of a fitted panel, e.g. a glass panel, influences the insulation value of the window frame profile/window frame structure. The deeper the isolator/thermally insulating element, the better the insulation value. The relatively shallow isolator relatively limits the thermal insulation value of the window frame profile.
This aspect of the invention concerns the provision of an insulated window frame profile/window frame structure with holder for glass laths, wherein the holder is integrated in the isolator/thermally insulating element. In this way, the depth of the isolator is not limited to the location of the holder of the glass lath in the shell part which does not give good insulation. Therefore the isolator can allow the omission of a shell part. The window frame profile may thus consist of only two shell parts, namely the first (metal, e.g. aluminium) window frame profile and the thermally insulating element, instead of three, namely the first (metal, e.g. aluminium) window frame profile, the second (metal, e.g. aluminium) window frame profile and the thermally insulating element which connects the first and second window frame profiles together. Because the isolator is deeper, the insulation value of the profile/window frame structure is improved and hence also the insulation value of the total window frame.
This aspect of the invention relates to the holder of the glazing rubber/first flexible profile of insulated window frame systems (steel, aluminium etc.). Such window frame systems are suitable for windows or doors. For sealing (air and water) of panels or glazing in window frame systems, glazing rubbers are attached to the window frame profile; the first flexible profile comprises a first sealing element which can be coupled to at least the first window frame profile and a first plate of a first panel which can be received in the window frame system. The glazing rubbers are attached, in specific recesses/holders, to a shell part of the assembled profile. However, by fixing these rubbers to a shell part of the insulated profile, the depth of the isolator is restricted to the location of the rubber in the holder of the shell part. The depth of the isolator/thermally insulating profile influences the insulation value of the window frame profile. The deeper the isolator/thermally insulating element, the better the insulation value. The relatively shallow isolator relatively limits the thermal insulation value of the window frame profile.
This aspect of the invention is oriented at the provision of an insulated window frame profile with holder for rubbers, wherein the holder is integrated in the isolator. The first flexible profile comprises at least a first and a second coupling element, which coupling element—which may or may not be form-fitted—can be received in respectively the second holder of the at least first window frame profile and the third holder of the at least first thermally insulating element. In this way, the depth of the isolator is not limited to the position of the holder of the rubber in the shell part which does not provide good insulation. The isolator may even allow the omission of a shell part, namely the second window frame profile. The window frame profile may thus consist of only two shell parts, namely the first (metal, e.g. aluminium) window frame profile and the thermally insulating element, instead of three, namely the first (metal, e.g. aluminium) window frame profile, the second (metal, e.g. aluminium) window frame profile and the thermally insulating element which connects the first and second window frame profiles together. Because the isolator is deeper, the insulation value of the profile/window frame structure is improved and hence also the insulation value of the complete window frame.
This aspect of the invention relates to the holder of the seals (glazing, opening leaf, centre seal etc.) of window frame systems (steel, aluminium, plastic or wood). Such window frame systems are suitable for windows or doors. To make the window frame for a window or door airtight and watertight, usually soft plastic (EPDM, silicones, TPE etc.) seals are placed in specific recesses/holders. However, because the corners of these recesses are rounded, which is necessary for the application of a surface treatment, the dimensions of the recesses are relatively large. The minimum radius of corners for the correct application of a surface treatment is 0.5 mm. Due to the relatively large dimensions of these recesses, the overall window frame profile is relatively large. A panel of insulating glass supported by the window frame profiles has a better thermal insulation value than the metal insulated profiles. Due to the relatively wide aluminium profiles, the thermal insulation value of the window frame is relatively limited.
This aspect of the invention concerns the provision of a profile with holder for glass laths, wherein the dimensions of the holder are minimised with corners with a radius smaller than 0.5 mm. This does not take into account the minimum dimensions required for surface treatment. This is achieved in the window frame system according to the invention by using the holders in the system exclusively where no surface treatment is required. In this way, the dimensions of the window frame profile may be smaller than in window frame profiles already known. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.
This aspect of the invention concerns the holder for the glass laths (glazing, opening leaf, centre seal etc.) of window frame systems (steel, aluminium, plastic or wood). Such window frame systems are suitable for windows or doors. To fix panels or glazing in window frame systems, glass laths are attached to the window frame profile after the panel or glazing has been placed in the window frame. These glass laths are fixed into specific recesses/holders. However, because the corners of these recesses are rounded, which is necessary for the application of a surface treatment, the dimensions of the recesses are relatively large. The minimum radius of corners for the correct application of a surface treatment is 0.5 mm. Due to the relatively large dimensions of these recesses, the overall window frame profile is relatively large. A panel of insulating glass supported by the window frame profiles has a better thermal insulation value than the metal insulated profiles. Due to the relatively wide aluminium profiles, the thermal insulation value of the window frame is relatively limited.
This aspect of the invention concerns the provision of a profile with holder for glass laths, wherein the dimensions of the holder are minimised with corners with a radius smaller than 0.5 mm. This does not take into account the minimum dimensions required for surface treatment. This is achieved in the window frame system according to the invention by using the holders in the system exclusively where no surface treatment is required. In this way, the dimensions of the window frame profile may be smaller than in window frame profiles already known. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.
This aspect of the invention concerns the holder for the glass laths (glazing, opening leaf, centre seal etc.) of insulated window frame systems (steel, aluminium, etc.). Such window frame systems are suitable for windows or doors. To fix panels or glazing in window frame systems, glass laths are attached to the window frame profile after the panel or glazing has been placed in the window frame. These glass laths are fixed into specific recesses/holders. However, by creating a non-integrated holder on the profile, the dimensions of the profile are relatively large. A panel of insulating glass supported by the window frame profiles has a better thermal insulation value than the metal insulated profiles. Due to the relatively wide aluminium profiles, the thermal insulation value of the window frame is relatively limited.
This aspect of the invention concerns the provision of a profile with holder for glass laths, wherein the holder is integrated with the holder for the isolator. In this way, the dimensions of the window frame profile may be smaller than in window frame profiles already known. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.
This aspect of the invention relates to the fixing of the isolator (composite, plastic) of insulated window frame systems (steel, aluminium etc.). Such window frame systems are suitable for windows or doors. For the thermal interruption of the relatively highly conductive metal (aluminium, steel etc.) profiles, the outer shell is connected to the inner shell by means of one or more isolators, a part with poor thermal conduction (composite, plastic etc.). For this, the isolator is clamped in a holder on both shell parts of the profile. The feet of the holder are clamped; bent over the length of the profile or repeatedly compressed. However, by the creation of a clamping holder, the dimensions of the profile are relatively large. The holder of the metal half-shell must namely either be pressed over a widened end of the isolator, or the holder of the half-shell must be made of such thick material that it can be pressed into the isolator. A panel of insulating glass supported by the window frame profiles has a better thermal insulation value than the metal insulated profiles. Due to the relatively wide aluminium profiles, the thermal insulation value of the window frame is relatively limited.
This aspect of the invention concerns the provision of a fixing of the isolator to the metal half-shells, wherein the isolator is glued in the holders of the half-shells. In this way the dimensions of the isolator and the holders of the half-shells and hence the window frame profile may be smaller than in window frame profiles already known. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.
This aspect of the invention relates to the isolator (composite, plastic etc.) of insulated window frame systems (steel, aluminium etc.). Such window frame systems are suitable for windows or doors. For the thermal interruption of the relatively highly conductive metal (aluminium, steel etc.) profiles, the outer shell is connected to the inner shell by means of one or more isolators, a part with poor thermal conduction (composite, plastic etc.). If a single isolator is used in the profile, this must be able to transmit the whole of the mechanical force between the two shell parts of the profile. For this, the isolator must be dimensioned sufficiently wide. The heat transmission between the two shell parts of the profile takes place via the thermal conduction of the isolator. The wider the isolator, the easier/the more heat can be conducted by the isolator and hence by the assembled profile.
This aspect of the invention concerns the provision of a hollow isolator for insulated window frame systems, wherein the heat transmission through the profile is limited but the mechanical properties remain as high as possible. In this way, the insulation value and strength of the assembled window frame profile is as high as possible. This may be advantageous for the total insulation value of the window frame and the quantity of material required/used for the window frame profiles.
This aspect of the invention relates to the seal (glazing seal, seal against building etc.) of insulated window frame systems (steel, aluminium etc.). Such window frame systems are suitable for windows or doors. For sealing the glazing and panels received in the window frame profiles, and to seal the window frame to the building frame, a seal is received in the window frame on the outside. This seal serves to close the system as water-tightly and air-tightly as possible. By now integrating a second seal in this rubber, it is possible to discharge water which may still pass the first seal via the compartment created in this way before it actually reaches the interior. The second seal in addition ensures an extra air-tightness of the system. The air pressure differences between interior and exterior are further compartmentalised, whereby the first (outermost) compartment can be drained more easily towards the outside.
To ensure a minimum width of the window frame profiles, the system for opening and closing window leaves/window frame structures should also be integrated in the window frame system without this adversely affecting the width of the profiles.
This aspect of the invention concerns an opening system/control system which is integrated in the window leaf. The control system comprises a motor which can be coupled to at least one of the window frame profiles of the window leaf/window frame structure, and a control unit which is configured for controlling the motor which can open and close the window leaf The motor may be installed behind a post/upright of the window leaf or may be integrated in a glass lath.
To ensure a minimum width of the window frame profiles, the system for opening and closing window leaves/window frame structures should also be integrated in the window frame system without this adversely affecting the width of the profiles.
This aspect of the invention concerns an opening system/control system which is integrated in the glass lath.
To provide a minimum width of the window frame profiles, the suspension and closure fitting for opening and closing the window leaves should also be integrated in the window frame system, without this adversely affecting the width of the profiles. The window leaves/window frame structures comprise fixing elements for connecting the window leaves to the window frame system. Furthermore, the fixing elements are configured for transferring the window leaves from a first closed state to a second, at least partially open state. The window leaves furthermore comprise locking mechanisms/locks for locking and unlocking the window leaves of the window frame system. This aspect of the invention concerns suspension and closure fittings which are integrated in the glass lath. This means that in one embodiment of the window frame system according to the invention, the fixing elements and/or the locking mechanisms of the window leaves may be integrated in the glass lath. The fixing element may be a hinge which can be integrated in the glass lath. The locking mechanisms may be locks which can be integrated in the glass lath.
To ensure a minimum width of the window frame profiles, the sun protection should be integrated in the window frame system. This aspect of the invention concerns a sun protection which is integrated in the glass laths.
This aspect of the invention concerns the isolator (plastic, composite etc.) of insulated window frame systems (steel, aluminium etc.). Such window frame systems are suitable for windows or doors. By minimising the profiles completely (omitting the protruding holders and making the half-shells solid) and by minimising the peripheral play around the glass, it is possible to determine the desired specifications of the window frame system by changing the composition of the isolator.
For bullet-proof window frame systems, the glass must be bullet-proof, the peripheral play around the glass must be smaller than the diameter of the bullet, and the isolator intended for this function must have a bullet-proof composition.
For fire-resistant window frame systems, the glass must be fire-resistant, the peripheral play filled with fire-resistant material (tape, film, paint etc.) and the isolator intended for this function must have a fire-resistant composition.
For sound-insulating window frame systems, the glass must be sound-insulating, the peripheral play around the glass filled with a sound-insulating material, and the isolator intended for this function must have a sound-insulating composition.
For thermally insulating window frame systems, the glass must offer good thermal insulation, the peripheral play must be filled with a material with good thermal insulation or stationary air, and the isolator intended for this function must have good thermal insulation.
By making the window frame profiles transparent, the quantity of light which enters is maximised. For this, the required window frame dimension must be minimised in order to allow sufficient daylight in the room. A smaller window frame may suffice, whereby a wall with better insulation may be used instead.
This aspect of the invention concerns an autonomously functioning control system which opens or closes the window leaf according to local needs (CO2 concentration, temperature, relative humidity or other factors).
This autonomous control system controls the ventilation locally (per window frame, per room). No central control system is required; each control system individually controls the respective window leaves in order to create the required ventilation. The ventilation can thus be regulated highly accurately. If local ventilation is required, ventilation is provided, and if no ventilation is required, no ventilation is provided. In this way, no heat is wasted unnecessarily.
This aspect of the invention concerns glazing seals (the seal for glazing and panels) which are formed such that a wet glazing seal or mastic can be applied. This seal allows the glazing to be applied with hook-mounted or click-fit glass laths, after which a wet seal is applied by means of mastic.
This aspect of the invention concerns the glass lath (metal, plastic, composite etc.) of insulated window frame systems (steel, aluminium, plastic, composite etc.).
Such window frame systems are suitable for windows or doors. This aspect of the invention concerns glass laths made of two parts, a lower part and a second upper part. In this way it is possible to determine the finish of the glass laths by means of the second upper part. This finish may be applied, modified or renewed while the window frame is already glazed and remains glazed.
This aspect of the invention concerns a window frame system in which the surface finish of the glass laths is applied in a line with the extrusion or pultrusion of the glass laths.
Co-Extrudable Window Frame System
This aspect of the invention concerns a window frame system in which the surface finish of the window frame profiles is applied in a line with the extrusion or pultrusion of the profiles.
According to further aspects of the invention, window frame systems and isolators are provided which comprise biological material.
In the embodiment shown in
In the embodiment of the window frame system shown in
The flexible profile 13 forms an external sealing rubber for closing the window frame system to a building frame as water-tightly and air-tightly as possible. The flexible profile 13 furthermore comprises a first coupling element 14 and the second coupling element 19 which are received by form-fit in respectively the third holder 5 and the second holder 4 of the first window frame profile 2 of the first window frame structure 23.
The second 4 and the third 5 holders of the first window frame profile 2, and the fifth holder 8 of the second window frame profile 7, comprise an internal corner with a radius which is smaller than 0.5 mm. The second window frame structure 50 is constructed in a similar manner to the first window frame structure 23, with the difference that the first 2 and the second 7 window frame profiles and the thermally insulating connecting element 10 of the first window frame structure 23 have a different shape from the first 2 and the second 7 window frame profiles and the thermally insulating connecting element 10 of the second window frame structure 50.
For producing an airtight and watertight window frame system for a window or a door, comprising at least one of the materials steel, aluminium, plastic or wood, normally seals are used, namely external or glazing seals, opening leaf seals, centre seals and internal seals, which comprise a soft plastic such as for example ethylene-propylene-diene monomer (EPDM), silicones and thermoplastic elastomers (TPE). These seals are placed in specifically provided recesses or holders 4, 5, 9. However, because the corners of these holders are usually rounded, which is necessary for the application of a surface treatment, the dimensions of these holders are relatively large. The minimum radius of corners for the correct application of a surface treatment is 0.5 mm. Due to the relatively large dimensions of these recesses, the total window frame profile is relatively large. A panel of insulating glass supported by window frame structures has a better thermal insulation value than the metal insulated window frame structures. Due to the relatively wide aluminium profiles, the thermal insulation value of the window frame is however relatively limited.
By using holders 4, 5, 9 with internal corners which have a radius smaller than 0.5 mm, no account is taken of the minimum dimensions of holders which are required if the window frame profiles are provided with a surface treatment. In the case of the window frame system 1 according to the invention, this is also not required since the holders for seals, such as the holders 4, 5, 9 of the first 2 and second 7 window frame profiles, are used exclusively where no surface treatment of the window frame profiles 2, 7 is necessary. Since the holders 4, 5, 9 do not widen the profile, the dimensions of the window frame profiles 2, 7 may be smaller than in window frame profiles known from the prior art. This may be advantageous for the total insulation value of the window frame system 1 and for the quantity of material required or used for the window frame profiles 2, 7.
For the fixing of panels or glazing in window frame systems, glass laths are attached to the window frame profile after the panel or glazing has been placed in the window frame system. These glass laths are attached in recesses/holders provided for this. As shown in
By using holders for glass laths, such as holder 9 of the second window frame profile 7, wherein these holders have an internal corner which has a radius smaller than 0.5 mm, no account is taken of the minimum dimensions of holders which are required if the window frame profiles are provided with a surface treatment. In the case of the window frame system 1 according to the invention, this is also not required since the holders for glass laths, such as the holder 9, are used exclusively where no surface treatment of the window frame profiles 2, 7 is necessary. Since the holders for glass laths, such as holder 9, do not widen the profile, the dimensions of the window frame profiles 2, 7 may be smaller than in window frame profiles known from the prior art. This may be advantageous for the total insulation value of the window frame system 1 and for the quantity of material required or used for the window frame profiles 2, 7 and hence for the window frame structures 23, 50.
For the thermal interruption of the relatively highly conductive metal window frame profiles of a window frame structure of the window frame systems known in the prior art, the window frame profiles of which comprise for example aluminium or steel, the window frame profiles are connected via one or more elements with poor thermal conduction, comprising a composite or plastic. For this, a thermally insulating element is clamped in holders provided for this and aligned on both metal window frame profiles of the window frame structure. The holders, i.e. the edges of a receiver space of the holders concerned, are clamped i.e. bent over a length of the thermally insulating element over which the thermally insulating element extends into the holder. Another possibility is that the edges of the holder are compressed at repeated intervals over said length of the thermally insulating element. However by creating such clamping holders, the dimensions of the thermally insulating profile become relatively large. In a known embodiment, the holders of the metal window frame profiles, also known as metal half-shells are pressed over a widened end of the isolator. According to another known embodiment, the holders may comprise protruding parts which are dimensioned, i.e. made of a thick material, such that they can be pressed into the thermal isolator. As already stated above, a panel of insulating glass supported by window frame structures has a better thermal insulation value than the metal insulated window frame structures. Due to the relatively wide aluminium profiles, the thermal insulation value of the window frame system is relatively limited.
In an embodiment of the window frame structures 23, 50 according to the invention, the first end 11 of the thermally insulating connecting element 10 is connected to the first holder 3 of the first window frame profile 2 by means of an adhesive connection. The second end 12 of the thermally insulating connecting element 10 is also connected to the fourth holder 8 of the second window frame profile 7 by means of an adhesive connection. In this way, the dimensions of the thermally insulating connecting element 10, the first holder 3 and the fourth holder 8 can be reduced relative to a holder known from the prior art. Consequently, the dimensions of the first 2 and second 7 window frame profiles may be smaller than in window frame profiles known from the prior art. This may be advantageous for the total insulation value of the window frame system 1 and for the quantity of material required or used for the window frame profiles 2, 7 and hence for the window frame structures 23, 50.
In another embodiment of the window frame structures 23, 50, the thermally insulating connecting element 10 may be configured such that it can be connected by means of an adhesive connection and/or a mechanical connection to the first holder 3 of the first window frame profile 2. The mechanical connection may be at least one of a punch connection, a clamp connection, a rivet connection, a push-fit connection and a screw connection.
As already described above, for the thermal interruption of the relatively highly conductive metal window frame profiles of a window frame structure of the window frame systems known from the prior art, in which the window frame profiles comprise for example aluminium or steel, the window frame profiles are connected via one or more elements offering poor thermal insulation, comprising a composite or plastic. If a single thermally insulating connecting element is used in the window frame structure, this must be able to transfer the whole of the mechanical force between the two window frame profiles of the window frame structure. For this, the single thermally insulating connecting element must be dimensioned sufficiently wide. The heat transfer between the two metal window frame profiles of the window frame structure takes place via thermal conduction of the single thermally insulating connecting element. The wider this thermally insulating connecting element, the more heat or the easier the heat is conducted by the thermally insulating connecting element and hence by the window frame structure as a whole.
In an embodiment of the window frame system 1 as shown in
This may be advantageous for the total insulation value of the window frame system 1 and for the quantity of material required or used for the window frame profiles 2, 7 and hence for the window frame structures 23, 50.
As already described above, in the window frame system 1 according to the invention, flexible profiles 13 are used as an external sealing rubber for closing the window frame system to a building frame as water-tightly and air-tightly as possible.
Insulated window frame systems (not steel) have specific protruding holders for various components which are assembled or connected to the window frame structures, such as fittings and/or glass laths, whereby the window frame structures become wider and adversely affect the insulation value of the total window frame system. By omitting these protruding holders from the window frame system, the window frame structures (insulated aluminium, plastic, composite, bio-composite, rubber) are minimised in directions transverse to the length direction of the window frame structure 23, such as for example the width of the window frame structure 23. In this way, the insulation value of the window frame system, in which the window frame structure 23 is used, can be improved.
In one embodiment of the window frame structure 23 as shown in
As already described, embodiments of the window frame system according to the invention are possible in which the window frame system comprises at least one of a biological material, a plastic, a composite material and a flexible material. By using one of these materials or a combination of these materials, it is possible to create window frame systems which have at least one of bullet-proof, fire-resistant, sound-insulating and thermally insulating properties. Furthermore, it is possible that the first window frame profile, the thermally insulating connecting element and second window frame profile are integrated by making these from the same material. In this way, a thermally insulated window frame structure may be produced from at least one of for example a plastic, a biological material, a composite, a bio-composite and a flexible material. It will be evident to the person skilled in the art that a number of possible materials and combinations of materials are possible within the concept of the invention. It will also be clear that the use of these materials and material combinations offers numerous construction and/or integration possibilities for creating window frame structures and window frame systems according to the invention. It is for example possible to make the first window frame profile 2 and the second window frame profile 7 of at least one of aluminium, an aluminium alloy and anodised aluminium. The first thermally insulating connecting element 10, as already described above, may comprise at least one of a biological material, a plastic, a composite material, a bio-composite material and a flexible material.
Although not shown, in one embodiment of at least one of the window frame system and window frame structure according to the invention, the at least first window frame profile 2 and the at least first thermally insulating connecting element 10 may form an integrated whole, i.e. be made of one piece. In this case, the second window frame profile 7 may be connected to the integrated whole by the end 12 of the whole being received in the fourth holder 8 of the second window frame profile 7.
Although also not shown, the person skilled in the art will understand that, similarly, it is possible that according to one embodiment of at least one of the window frame system and window frame structure according to the invention, the at least first thermally insulating connecting element 10 and the least second window frame profile 7 may form an integrated whole. In this case, the first window frame profile 2 may be connected to the integrated whole by the end 11 of the whole being received in the first holder 3 of the first window frame profile 2.
