[0115] The figures are not necessarily drawn to scale. Identical or similar components may be indicated with the same references in the different figures.

[0116] 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. All conceivable combinations of the described aspects of the invention fall within the scope of protection of this invention.

[0117] 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.

[0118] 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

[0119] 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.

Holder for Glass Lath for Window Frame Systems at Isolator

[0120] 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.

[0121] 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.

Holder for Glazing Rubber for Window Frame Systems at Isolator

[0122] 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.

[0123] 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.

Rubber Holder for Window Frame Systems With Sharp Edges

[0124] 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.

[0125] 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.

Holder for Glass Lath for Window Frame Systems With Sharp Edges

[0126] 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.

[0127] 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.

Holder for Glass Lath for Window Frame Systems at Fixing of Metal Half-Shell and Isolator

[0128] 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.

[0129] 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.

Glued Fixing of Isolator in Half-Shells

[0130] 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.

[0131] 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.

Hollow Isolator

[0132] 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.

[0133] 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.

Outer Seal With Integrated Centre Seal

[0134] 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.

System for Controlled Opening of Window Leaves Integrated in System Behind the Post of the Window Leaf

[0135] 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.

[0136] 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.

System for Controlled Opening of Window Leaves Integrated in the Glass Lath

[0137] 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.

[0138] This aspect of the invention concerns an opening system/control system which is integrated in the glass lath.

Window Leaf Suspension and Closure Fittings Integrated in the Glass Lath

[0139] 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.

Sun Protection (Screen, Blinds) Integrated in the Glass Lath

[0140] 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.

Function-/Performance-Determining Composite Isolator

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

Transparent Window Frame System

[0146] 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.

Autonomous Control System for Opening/Closing Individual Window Leaves on the Basis of Individual Ventilation Needs

[0147] This aspect of the invention concerns an autonomously functioning control system which opens or closes the window leaf according to local needs (CO.sub.2 concentration, temperature, relative humidity or other factors).

[0148] 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.

Mastic-Compatible Glazing Seal

[0149] 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.

Two-Part Glass Lath

[0150] This aspect of the invention concerns the glass lath (metal, plastic, composite etc.) of insulated window frame systems (steel, aluminium, plastic, composite etc.).

[0151] 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.

Co-Extrudable Glass Lath

[0152] 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.

[0153] Co-Extrudable Window Frame System

[0154] 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.

[0155] According to further aspects of the invention, window frame systems and isolators are provided which comprise biological material.

[0156] FIG. 1 shows a diagrammatic cross-section of an embodiment of a window frame system 1 according to the invention for fixing of at least a first panel 70. The window frame system 1 comprises a first window frame structure 23 which has a first window frame profile 2. The first window frame profile 2 is provided with a first holder 3 and a second holder 4. In the embodiment shown on FIG. 1, the first window frame structure 23 furthermore comprises a first thermally insulating element 10 which has a first end 11 and a second end 12, wherein the first end 11 is received in the first holder 3 of the first window frame profile 2, and the second end 12 is received in a fourth holder 8 of a second window frame profile 7. In this way, the first window frame profile 2 and the second window frame profile 7 are connected together in a thermally insulated fashion. The connection between the first end 11 and the first holder 3 firstly, and between the second end 12 and the fourth holder 8 secondly, may be achieved by at least one of an adhesive connection and a mechanical connection, or at least one of a punch connection, a clamp connection, a rivet connection, a push-fit connection and a screw connection. The use of said connecting methods has the advantage that in this way, the dimensions of the first thermally insulating element 10, the first holder 3 and the fourth holder 8, and hence of the first window frame structure 23, may be smaller than in known window frame structures. This may be advantageous for the total insulation value of the window frame system 1 and the quantity of material required/used for the window frame system 1.

[0157] In the embodiment shown in FIG. 1, the thermally insulating element 10 is provided with a sixth holder 106 and a seventh holder 107. The sixth holder 106 is oriented towards the second end 12, and the seventh holder 107 is oriented towards the first end 11 of the first thermally insulating element 10. Furthermore, the first window frame structure 23 comprises a first flexible profile 13 comprising a first sealing element 20 which is coupled to the first window frame profile 2 and a first plate 17 of the first panel 70 which is received in the window frame system 1 according to the invention. The first window frame structure 23 furthermore comprises a first glass lath 15 which is coupled to a second plate 18 of the first panel 70 and the first thermally insulating element 10. The second holder 4 of the first window frame profile 2 and the sixth holder 106 and the seventh holder 107 of the first thermally insulating element 10 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 1 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.

[0158] FIG. 1 furthermore shows that the first flexible profile 13 furthermore comprises a first coupling element 14 and a second coupling element 19, wherein the first coupling element 14 is received in the second holder 4 of the first window frame profile 2, and the second coupling element 19 is received in the sixth holder 106 of the first thermally insulating element 10. In the embodiment of the window frame system 1 as shown in FIG. 1, the first glass lath 15 comprises a third coupling element 16 which is received in the seventh holder 107 of the first thermally insulating element 10.

[0159] FIG. 1 furthermore shows that the first window frame profile 2 and the second window frame profile 7 are provided with a first cavity 22, which forms an open passage between a first side and a second side of the respective window frame profile 2, 7. The cavity 22 may have the function of a screw channel which allows the window frame profiles, positioned at right angles to each other, to be connected together by means of at least one screw connection.

[0160] In the embodiment of the window frame system shown in FIG. 1, the first thermally insulating element 10 is an elongated strip which is provided with a cavity 40. In this way, it is possible to limit the heat transfer through the window frame profiles while the mechanical properties remain as high as possible. Furthermore, in this way, it is possible to make the insulation value and strength of the assembled window frame profiles as high as possible. The first thermally insulating element 10 may comprise at least one of a bullet-proof material, a fire-resistant material and a sound-insulating material. A material with at least one of said properties may be at least one of a biological material, a composite material, a plastic, a fibre-reinforced material and a flexible material. The flexible material may comprise an armoured flexible material. It will be evident to the person skilled in the art that the use of at least one of these materials or combinations thereof allows numerous construction and/or integration possibilities for creating the window frame structures and window frames systems according to the invention. It will be clear to the person skilled in the art that the entire window frame system 1 according to the invention may be made from at least one of the above-mentioned materials with at least one of the above-mentioned properties.

[0161] FIG. 2 shows a diagrammatic cross-section of exemplary embodiments of two window frame structures 23, 50 of a window frame system 1 according to the invention for the fixing of a panel. The first window frame structure 23 is connected to a first panel 70. In the example of FIG. 2, the first panel 70 comprises an assembly of a first 17, a second 18 and a third glass plate 51. The second window frame structure 50 is connected to a second panel 71 which, in the example of FIG. 2, is also an assembly of a first 17, a second 18 and a third glass plate 51. It will be clear to the person skilled in the art that the second panel 71 may be any other desired type of panel.

[0162] FIG. 2 furthermore shows that the first window frame structure 23 comprises a first window frame profile 2 which is provided with a first 3, a second 4 and a third holder 5. Furthermore, the first window frame structure 23 comprises a second window frame profile 7 which is provided with a fourth 8 and a fifth holder 9. The first window frame profile 2 and the second window frame profile 7 are positioned relative to each other such that the first 3, the second 4 and the third 5 holders of the first window frame profile 2 are oriented towards the fourth 8 and the fifth 9 holders of the second window frame profile 7. The first window frame structure 23 furthermore comprises a thermally insulating connecting element 10 which comprises a first end 11 and a second end 12. The first end 11 of the thermally insulating element 10 is received in the first holder 3 of the first window frame profile 2. The second end 12 is received in the fourth holder 8 of the second window frame profile 7, for connecting together the first 2 and the second 7 window frame profiles.

[0163] FIG. 2 furthermore shows that the first window frame structure 23 comprises a flexible profile 13 which comprises a sealing element 20 positioned in lying contact with the first window frame profile 2 and the first glass plate 17 of the first panel 70.

[0164] 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.

[0165] FIG. 2 furthermore shows that the first window frame structure 23 comprises a glass lath 15 containing a third coupling element 16 which is received by form-fit in the fifth holder 9 of the second window frame profile 7. The glass lath 15 is applied after the first panel 70 has been positioned and is connected to the second glass plate 18 of the first panel 70 via an internal sealing rubber 80.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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 FIG. 2, the third coupling element 16 of the glass lath 15 is received in the fifth holder 9 of the second window frame profile 7 of the first window frame structure 23. The glass lath 15 is connected to the second glass plate 18 of the first panel 70 via an internal sealing rubber 80. In this way, the first panel 70 is held in place in the window frame system 1. However the corners of the holders for fixing the glass laths are usually rounded in conventional window frame systems and have a minimum radius of 0.5 mm. As already stated above, a minimum radius of 0.5 mm is required for the uniform application of a surface treatment. Because of this minimum radius of the corners of the holders for the glass laths, the dimensions of these holders are relatively large. Thus the dimensions of window frame profiles are relatively large, at least in directions transverse to the length direction of the window frame structures of conventional window frame systems. 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 a conventional window frame system is relatively limited because the surface area of the glass panels offering better insulation is smaller than it might be.

[0170] 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.

[0171] FIG. 2 shows that the first holder 3 which receives the first end 11 of the thermally insulating connecting element 10, and the third holder 5 which receives the first coupling element 14 of the flexible profile 13, are integrated. FIG. 2 also shows that the fourth holder 8 which receives the second end 12 of the thermally insulating connecting element 10, and the fifth holder 9 which receives the third coupling element 16 of the glass lath 15, are integrated. By integrating the holders for the thermally insulating connecting element and the glass laths, 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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] In an embodiment of the window frame system 1 as shown in FIG. 2, the thermally insulating connecting element 10 is provided with a cavity 40. It will be evident to the person skilled in the art that the thermally insulating connecting element 10 may be provided with more than one cavity 40. By providing the thermally insulating connecting element 10 with a cavity 40, the heat transfer through a window frame structure 23, 50 according to the invention may be limited, while the mechanical properties remain as high as possible. In this way, the insulation value and strength of the window frame structures 23, 50 according to the invention are as high as possible.

[0177] 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.

[0178] 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. FIG. 3 shows a diagrammatic cross-section of a further exemplary embodiment of a window frame structure 23 according to the invention which comprises two flexible profiles 13, each of which has a second sealing element 21. The second sealing element 21 of the first flexible profile 13 is positioned in lying contact with the first window frame profile 2 and the first glass plate 17 of an insulating panel 72. The second sealing element 21 of the second flexible profile 13 is positioned in lying contact with the first window frame profile 2 and a wall 60.

[0179] FIG. 3 furthermore shows that the first 20 and second 21 sealing elements of the flexible profile 13 form a first channel 30 for the discharge of a fluid, for example water, which has penetrated past the first sealing element 20 during use of the window frame system 1. By integrating the second sealing element 21, which serves as a centre seal, with the flexible profile 13, the channel 30 is produced which is limited by the first sealing element 20, the second sealing element 21 and the wall 60. In this way, the water which penetrates past the first sealing element 20 can be captured in the channel 30 and discharged to the outside before it actually penetrates the building frame. The second sealing element 21 in addition ensures an extra airtightness of the window frame system 1. The air pressure differences between interior and exterior are compartmentalised further, whereby the first (outermost) channel/compartment 30 can be drained towards the outside more easily.

[0180] 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. FIG. 4a shows a diagrammatic cross-section of an embodiment of the window frame structure 23 as shown in FIG. 3. The window frame structure 23 shown diagrammatically in FIG. 4a comprises first 2 and second 7 window frame profiles which consist of a metal, for example at least one of aluminium, an aluminium alloy, anodised aluminium and steel. The first 2 and second 7 window frame profiles are connected via a thermally insulating connecting element 10 which comprises a first end 11 and the second end 12. The first end 11 of the thermally insulating element 10 is received in the first holder 3 of the first window frame profile 2. The second end 12 is received in the fourth holder 8 of the second window frame profile 7.

[0181] FIG. 4a furthermore shows that the first window frame profile 2 of the embodiment of the window frame structure 23 is provided with a second 4 and a third holder 5 which form integrated holders for a flexible profile 13 which forms an external sealing rubber for closing a window frame system 1 according to the invention against a building frame as water-tightly and air-tightly as possible. As shown in FIGS. 2 and 3, the flexible profile 13 comprises first 14 and second 19 coupling elements which may be received by form-fit in respectively the third holder 5 and the second holder 4.

[0182] FIG. 4a furthermore shows that the second window frame profile 7 of the embodiment of the window frame structure 23 is provided with a fifth holder 9 which forms an integrated holder for a glass lath 15. As shown in FIGS. 2 and 3, the glass lath 15 comprises a third coupling element 16 which may be received by form-fit in the fifth holder 9 of the second window frame profile 7. It will be clear to the person skilled in the art that the window frame structure 23 as shown in FIG. 4a is fully minimised by making the window frame profiles 2, 7 solid and omitting protruding, profile-widening holders, for example for fittings and/or glass laths according to the prior art, and instead creating the integrated holders 4, 5, 9 described above.

[0183] In one embodiment of the window frame structure 23 as shown in FIG. 4a, the thermally insulating connecting element 10 is provided with a cavity 40. It will be clear to the person skilled in the art that the thermally insulating connecting element 10 may be provided with more than one cavity 40. By providing the thermally insulating connecting element 10 with a cavity 40, the heat transfer through a window frame structure 23, 50 according to the invention can be limited while the mechanical properties remain as high as possible. In this way, the insulation value and strength of the window frame structures 23, 50 according to the invention are as high as possible. 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.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] FIG. 4b shows a diagrammatic cross-section of another exemplary embodiment of a window frame structure 23 according to the invention, in which the first window frame profile 2, the thermally insulating connecting element 10 and the second window frame profile 7, as shown in FIGS. 2, 3 and 4a, are integrated by being made of the same material. In the embodiment of the window frame structure 23 shown in FIG. 4b, the first window frame profile 2, the first thermally insulating connecting element 10 and the second window frame profile 7 form an integrated whole, i.e. they are made of one piece of the same material or same material combination. In this way, a thermally insulated window frame structure 23 is produced from one piece, and may be used in a window frame system 1 according to the invention. The window frame structure 23 as shown in FIG. 4b is fully minimised by creating the integrated holders 4, 5, 9 described above for fixing respectively a flexible profile 13 and a glass lath 15, as shown in FIGS. 2 and 3, instead of protruding profile-widening holders known from the prior art.

[0188] FIG. 4b furthermore shows that the window frame structure 23, made for example completely out of one piece of composite, is provided with a cavity 40. It will be evident to the person skilled in the art that in this way, the heat transfer through the window frame structure 23 can be limited further while the mechanical properties remain as high as possible.

[0189] FIG. 4c shows a diagrammatic cross-section of yet another embodiment of a window frame structure 23 according to the invention, which is formed by the flexible sealing profiles 13, the thermally insulating connecting element 10 and the second window frame profile 7—as shown in FIGS. 2 and 3—being integrated into a whole by producing these of the same material, i.e. from one piece of the same material or same material combination. The window frame structure 23 shown in FIG. 4c may furthermore be made for example from one piece of flexible material, armoured or otherwise, for example a rubber, armoured or otherwise, with the mechanical and strength properties which are suitable for use in a window frame system according to the invention. In this way, the window frame structure 23 may be made from one piece, which makes the use of the first aluminium window frame profile 2 shown in FIGS. 2, 3 and 4a superfluous.

[0190] The window frame structure 23 shown in FIG. 4c is also fully minimised by creating the integrated holder 9 for fixing of a glass lath 15—as shown in FIGS. 2 and 3—instead of protruding, profile-widening holders as known from the prior art. FIG. 5a shows a diagrammatic cross-section of an embodiment of a window frame system 1 according to the invention, in which a first motor 25 of a control system 24 is positioned relative to a first post 26 of a first window frame structure 23. The control system 24 is configured for controlling the first motor 25, which is configured for opening and/or closing the first window frame structure 23. The control system 24 may be configured for autonomously opening and/or closing the first window frame structure 23 depending on local environmental factors, such as the CO.sub.2 concentration, temperature and relative humidity of the ambient air. By using an autonomous control system 24 according to the invention in a window frame system 1 according to the invention, it is possible to regulate ventilation locally (per window frame, per room). No central control system is required. Each control system 24 according to the invention individually controls the respective window leaves in order to create the necessary ventilation. The ventilation can thus be regulated with great accuracy. If ventilation is required locally, ventilation is provided, and if no ventilation is required, no ventilation is provided.

[0191] FIG. 5b shows a diagrammatic cross-section of another embodiment of a window frame system 1 according to the invention, in which the first motor 25 of the control system 24 is integrated in the first glass lath 15 of the first window frame structure 23.

[0192] FIG. 6 shows a diagrammatic cross-section of a further embodiment of a window frame system 1 according to the invention, in which a sun protection system 31 is integrated with the first glass lath 15 of the first window frame structure 23 of the window frame system 1. In this way, it is possible to ensure a minimum width of the window frame structure. The sun protection system 31 according to the invention may comprise at least one of blinds and a screen.

[0193] FIG. 7 shows a diagrammatic cross-section of another embodiment of a window frame system 1 according to the invention, which is provided with a second flexible profile 32 applied to a side of the first glass lath 15 which is directed towards a second plate 18 of the first panel 70 received in the window frame system 1. The second flexible profile 32 serves to close an opening between the second window frame profile 7 and the second plate 18. FIG. 7 furthermore shows that the second flexible profile 32 is applied over the first flexible profile 13 to close an opening between the first window frame profile 2 and the first plate 17 of the first panel 70. In the embodiment of the window frame system 1 according to the invention, the second flexible profile 32 comprises a mastic. As already described above, this aspect of the invention relates to glazing seals, i.e. the seals for glazing and panels which are formed such that a wet glazing seal or mastic may be applied. This seal allows the glazing to be applied with hook-mounted or click-fit glass laths 15, after which a wet seal is applied by means of mastic 32.

[0194] The present invention is not restricted to the non-limitative exemplary embodiments described above. The scope of protection is determined by the extent of the following claims, within the scope of which many modifications and technical equivalents are conceivable.
