Description

Profiled elements made of plastic material as well as casements and casement frames made of such a profiled element The present invention refers to a profiled element made of plastic material, particularly as a frame profile and casement or other glazing carriers as well as for window frames and the like.

It is known from the prior art of AT 410 350 B to arrange insets of polyurethane foam cores in some chambers of a profiled element for the manufacture of window or door frames. In view of the achievable heat transmission coefficients the solution described in AT 410 350 B is not satisfactory.

Against this background it was suggested in DE 20 2011 003 572 U2 to foam the chambers of a profiled element for casements or window frames with a foam material. In order to comply with the requirements made on passive houses, all chambers of the profiled element are at least substantially completely foamed by a polyurethane foam according to DE 20 2011 003572 Ui.

In the case of strong solar irradiation, a significant heating of the profiled sections of the casement or window frame forming the respective exterior facades may occur. This particularly applies in the case in which the profiled elements forming the respective window frame or the respective casement have a dark colour and can therefore only reflect a low portion of solar radiation.

When the exterior facade sections of the profiled elements heat up as a result of solar irradiation, the heat introduced by heat radiation into the profiled element is conducted through heat conduction to the insulation material. Particularly in the case of a longer lasting heat irradiation a heating of the interior facade sections of the casement or the window frame may occur despite the arrangement of insulation foam in the chambers of the profiled element, so that the heat insulation of the respective window frame or casement frame may be affected.

Against this background, the object of the invention is to provide a profiled element made of plastic material, in which the insulation properties in the case of strong and particularly longer lasting solar irradiation is improved. Furthermore a respective casement -hereinafter referred to as casement frame -and a window frame as well as a combination of these elements shall be provided as a complete window system.

According to the invention this object is solved with respect to the profiled element by the features of claim 1. Regarding the casement, a window frame and a combination of casement and window frame, the cited object is solved by the features of claims 17, 21, and 24, respectively, Preferred embodiments of the invention are described in the respective dependent claims and will subsequently be explained.

A profiled element according to the invention comprises at least one pre-chamber and at least one interior chamber, wherein the pre-chamber has a chamber wall, which at least section-wise forms an exterior facade wall of the profiled element, and wherein the interior chamber is formed by interior chamber walls.

An exterior facade wall is a wall section, which in assembled condition of the profiled element faces the outer environment and can consequently be exposed to solar irradiation. In contrast thereto, interior chamber walls are such walls that are arranged between the exterior facade wall of the profiled element as well as its interior facade wall, also including the interior facade wall. An interior facade wall means a wall section of the profiled element, which in the assembled condition faces the respective room of the facility or the building, which shall be separated by the respective window from the outer environment.

Consequently, an interior chamber in the assembled condition of the profiled element is delimited from the outer environment by at least one pre-chamber.

According to the invention it is provided that at least one pre-chamber is filled by a flowable medium. Should a strong heating of the exterior facade sections of the profiled element caused by solar irradiation occur, the heating energy introduced into the profile is first of all transferred to the flowable medium in the pre-chamber. Caused by the heating of the flowable medium, its movement or flow is again promoted so that a discharge of the heat energy introduced is enabled. At the same time the flow of the flowable medium ensures a convection cooling of the interior chamber wall opposing the exterior facade wall. This may particularly reduce the influence of heat conduction in the case of strong solar irradiation.

According to an advantageous embodiment of the invention, a plurality of pre-chambers and/or a plurality of interior chambers is provided. A larger amount of chambers within the profile can both improve its stability as well as its insulation characteristics. A specially favourable heat insulation in the case of strong solar irradiation can be ensured in that all pre-chambers are filled by a flowable medium.

Preferably at least one of the pre-chambers can be filled by ambient air, which can be managed at minimal effort. At the same time it can be advantageous that the at lest one pre-chamber is substantially free from insulation materials, by which a flow of the flowable medium can specially be promoted. Preferably all pre-chambers are free from insulation materials.

According to an especially preferred embodiment at least one of the pre-chambers comprises at least one venting opening. Such a venting opening can enable communication between the internal volume of the respective pie-chamber and the outer enviionment so that the air heated in the iespective pie-chamber of the profile flows out thiough the venting opening to the atmosphere and in contrast cooler ambient air flows into the respective pie-chamber of the profiled element. This can ensure an especially efficient heat discharge from the profiled element.

According to a further embodiment, the profiled element comprises at least two adjoining pre-chambers which are in fluid communication with each other by at least one venting opening.

Accordingly, this venting opening can particularly be formed on an internal chamber wall of the profiled element. In this manner the number of venting openings ensuring a direct fluid communication with the atmosphere can be reduced to a minimum. This particularly cieates the possibility to vent at least one of the pie-chambers directly via venting openings between the respective pre-chambers. Furthermore, a flow of flowable medium between the respective pre-chambers ensures a further improved heat discharge.

Furthermore, it can be advantageous if the at least one pie-chamber comprises at least two venting openings arianged in different chamber walls of the pie-chamber adjoining each other oi extending inclined to one another. This can reliably ensuie a sufficient circulation of the flowable medium between the pre-chambers of the profile and finally also between the pie-chambers and the atmosphere. This particularly applies if the respective profiled element extends vertically when installed, since heated air rises upwards and exits the pre-chamber at a venting opening located farther above in the facade height direction, and cooler air from the atmosphere flows through the ventilation slot into the pre-chamber at a venting opening located farther below in the facade height direction.

Likewise, there is an option that he at least one pre-chamber comprises at least two venting openings arranged at a spacing to one another along a longitudinal orientation of the profiled element or at an angle towards the longitudinal orientation of the profiled element. The venting openings can be arranged in one single chamber wall, e.g. the chamber wall forming the exterior facade. Depending on the horizontal or vertical installation orientation of the profiled element it can be ensured that both venting openings are arranged on different facade height positions and thereby a circulation of air through the pie-chamber is promoted, as was stated above.

The venting opening can also advantageously be formed slot-like. Such a venting opening can be provided at minimal effort. It can particularly be integrated into a chamber wall of the pre-chamber in the course of an extrusion process. At the same time a slot shape enables a favourable circulation of air between the respective pre-chambers as well as the atmosphere or two pre-chambers adjoining each other. A slot-shaped venting opening can substantially extend along the longitudinal orientation of the profiled element or at an angle to the longitudinal orientation of the profiled element. Particularly in the case that the slot-shaped venting opening is arranged at an exterior facade section of the profiled element the first mentioned orientation can be advantageous when the respective profiled element extends vertically in the installed condition. In contrast thereto, the last mentioned orientation of the slot-shaped venting opening must then be preferred, if the respective profiled element extends horizontally in the assembled condition. As described above this is caused by the fact that heated air rises up and exits the pre-chamber at a portion located farther above in the facade height direction, and cooler air from the atmosphere flows through the venting slot into the pre-chamber at a point located further below in the facade height direction.

But even without venting openings in the pre-chambers can advantages with respect to the heat insulation in the event of strong and longer lasting solar radiation be achieved by filling the pre-chambers by a flowable medium. The mere circulation of the medium within the individual pre-chambers enables that the heated medium flows past the profile sections of the respective casement or window frame which have a lower temperature than the heated exgterior facade sections. Due to these cooler profile sections the heat supplied can also be discharged to the atmosphere.

According to a further advantageous embodiment of the profiled element, at least one of the interior chambers is foamed by a foam material. Preferably, the interior chamber is substantially fully foamed by foam material. A "substantially completely" foamed chamber means that at least 75 % of the cross-sectional surface of the chamber are foamed. By such a foaming favourable insulation properties of the profiled element are ensured both in view of heat as well as in view of coldness. Preferably all internal chambers are substantially fully foamed by a foam material.

Furthermore, at least one of the interior chambers of the profiled element can be formed as an interior facade chamber, which is at least section-wise formed by an interior facade wall of the profiled element, wherein the interior facade chamber can also be foamed by a foam material. The interior facade chamber is preferably substantially fully foamed by foam material. In a plurality of interior facade chambers preferably all interior facade chambers can be foamed by a foam material, which further increases the insulation properties. The option also exists to provide one or a plurality of interior facade chambers free from insulation materials such as foam material.

Polyurethane foam can for instance be used for foaming the interior chambers and/or the interior facade chambers. Polyurethane foam has good insulation properties and can be processed easily.

For ensuring high mechanical rigidity, a reinforcement element can be provided in the at least one interior chamber. The reinforcement element can be embedded into the foam material in the interior chamber so that both favourable insulation properties as well as a high mechanical rigidity is ensured. At the same time the reinforcement element can serve as a isothermal guide element within the profiled element, which can also lead to an improvement of the insulation properties. The reinforcement element can be a profile, particularly an essentially C-shaped profile or box profile, which can be manufactured at low cost and which can also be inserted into the respective interior chamber at minimum effort. Such a profile can be made of steel, of glass fibre reinforced plastic material and the like in order to ensure the required mechanical rigidity.

In order to be able to use reinforcement elements having sufficient dimensions, the chamber volume of the interior chamber in which the reinforcement element is arranged can be larger than the chamber volume of other chambers. Likewise, a chamber volume of the at least pre-chamber can be larger than the chamber volume of a reinforcement-free interior chamber and/or than the chamber volume of an interior facade chamber. An appropriately spacious design of the pre-chamber on the one hand ensures a safe discharge of the heat energy supplied and on the other hand prevents a strong heating of an air volume existing in the respective pre-chamber.

It is particularly advantageous for providing a casement if the interior chamber with the reinforcement element is substantially arranged in a vertical extension of the at least one glass pane. In such an arrangement the reinforcement element can especially efficiently act as isothermal guide element.

A casement according to the invention is provided with an above-described profiled element.

For the case that the pre-chamber is provided with two venting openings, these openings are preferably arranged spaced apart from one another in vertical orientation, i.e. in an assembly position of the casement along the facade height direction, irrespective of whether the venting openings are formed on an exterior facade wall or an interior chamber wall. For the case that the pre-chamber of the profiled element is provided with a slot-shaped venting opening, this opening can extend in an advantageous manner substantially in a vertical orientation or substantially in a horizontal orientation. The first mentioned orientation is advantageous if the slot-shaped venting opening is formed on an exterior facade wall and extends in an assembly position of the casement in the facade height direction. The last mentioned orientation can, however, be used for slot-shaped venting openings on interior chamber walls.

A casement according to the invention is preferably equipped with a glass holding rail made of plastic material, which is foamed with foam material, particularly with polyurethane foam, which contributes to a further improvement of the insulation properties of the casement.

Likewise, a window frame according to the invention is equipped with a preceding profiled element. As also stated with reference to the above described casement, it is advantageous also in the case of a window frame with the arrangement of two venting openings, to arrange them in the assembly position of the window frame in a vertical orientation in a manner spaced apart from each other to promote the circulation of air, irrespective of whether the venting openings are formed on an exterior facade wall or an interior chamber wall. In the case of a slot-shaped design of venting openings a substantially vertical orientation as well as a substantially horizontal orientation can be advantageous to ensure a favourable circulation of air in the pre-chamber or between two adjoining pre-chambers.

An above described casement as well as an above described window frame can be combined with one another in a manner according to the invention to thereby provide a window system, which has favourable insulation properties in view of a strong and particularly longer lasting solar irradiation.

The invention will now be described in detail by means of embodiments and associated drawings: Fig. 1 shows a profiled frame of a casement according to an embodiment of the invention in cross-section.

Fig. 2 shows a combination of a casement with a window frame according to a first embodiment of the invention in cross-section.

Fig. 3 shows a combination of a casement with a window frame according to a second embodiment of the invention in cross-section.

Fig. 4 shows a combination of a casement with a window frame according to a third embodiment of the invention in cross-section.

Fig. 5 shows a combination of a casement with a window frame according to a fourth embodiment of the invention in cross-section.

Fig. 6 shows a combination of a casement with a window frame according to a fifth embodiment of the invention in cross-section.

Fig. 1 shows a profiled frame P of a casement 1 shown in Fig. 2. The profiled frame P -a glass pane 2 and a glass holding rail 4 are not shown in Fig. 1 -consists of a plurality of chambers 7, wherein some of the chambers 7 are formed as interior chamber 7a, and some of the chambers are formed as pre-chamber 7b. Furthermore, some of the interior chambers 7a are formed as interior facade chamber 7c. A reinforcement element, particularly a steel profiled element 9 is preferably inserted in the largest one of the interior chambers 7a.

For the further description, also for the description of the profiled frame P according to Fig. 1, reference is made to the following description of Fig. 2. Fig. 2 shows a cross-sectional view of a casement 1 comprising a laminated glass pane 2 inserted therein, which is shown schematically only, which is held on the casement 1 via sealing profiles 3 and a glass holding rail 4. In Fig. 2 the casement 1 is shown in connection with a window frame 5 with which the casement is in engagement or pressure engagement via sealing profiles 6.

The special features of the profiled frame F shown in Fig. 1 or the casement 1, hereinafter also referred to as casement frame 1, which comprises a plurality of chambers 7 is that at least one of the pre-chambers 7b is filled by a flowable medium 16. The flowable medium 16 can preferably be ambient air. In an advantageous manner the pre-chambers 7b are exclusively filled by ambient air 16 and are therefore free from insulation materials.

The pre-chambers 7b comprise at least one chamber wall, which at least section-wise forms an exterior facade wall 18 of the profiled element. Such an exterior facade wall 18 is heated by strong solar irradiation, whereby the flowable medium 16 in the respective pre-chamber 7b is heated and as a result it circulates within the pre-chamber 7b or flows through this chamber or flows out of it. The pre-chambers 7b are preferably provided with venting openings 17 through which heated ambient air 16 from the pre-chambers 7b can flow out of the pre-chambers 7b to the atmosphere U and cooler ambient air from the environment U can flow into the pre-chambers 7b. Preferably each of the pre-chambers 7b is equipped with at least two venting openings l7so that the circulation is promoted by the rising of the air 16 heated in the respective pre-chamber 7b. This particularly applies if the venting openings 17 are arranged on different height facade positions of the exterior facade wall 18.

As further shown in Fig. 2, all interior chambers 7a and 7c are filled or foamed by a polyurethane foam 8 as foam material, wherein the polyurethane foam 8 directly foams the interior chambers 7a and 7c of the casement frame 1. However, the interior chambers 7a and 7c are all preferably filled at least by 75 % with polyurethane foam. Furthermore, each of the foamed interior chambers 7a and 7c is filled at least by more than 75 %, preferably by up to 100% of its cross-sectional surface and thus it is fully filled.

A further special feature of the casement frame 1 is that in the largest one of the interior chambers 7a an open steel profile 9 as profiled enforcement element for the casement frame 1 is located, which is fully foamed into the polyurethane foam 8 and which is possibly supported at marginal projections 14 of the chamber wall of the respective interior chamber 7a. The steel reinforcement profile 9 serves for the static reinforcement of the casement frame 1, but at the same time as protection against burglary and furthermore acts as an isothermal guide element within the casement frame 1 in conjunction with the laminated glass pane 2, as was shown by measurements and simulation results. Regarding the effect of the steel reinforcement profile 9 as isothermal guide element, reference is made to the description in DE 20 2011 003 572 U2 and the associated Figures.

Fig. 2 also shows the window frame 5 in cross section, which in a corresponding manner comprises a plurality of chambers 11, some of which being formed as interior chamber ha and some of which being formed as pre-chamber 1 ic. Some of the interior chambers 1 ha are also formed as interior facade chamber 1 lc. In the window frame 5 the pre-chambers lib are also filled by a flowable medium 16, particularly ambient air, which can flow out through venting openings 19 introduced into the exterior facade wall 20. At the same time ambient air from the atmosphere U can flow into the pre-chambers lib through the venting openings 19.

The interior chambers ha and lic are preferably all, but at least in an amount of 75 %, foamed by foam material, particularly polyurethane foam 8. Each of the foamed interior chambers 1 la and 1 ic is filled over 75 %, preferably over up to 100 % of its cross-sectional surface and thus it is fully foamed. Likewise, a reinforcement element 12, preferably a hollow profile made of steel, which is also fully embedded in foam material 8, particularly polyurethane foam, is arranged in the largest one of the interior chambers 1 la, substantially in the vertical extension of the laminated glass pane 2 and the reinforced interior chamber 7a of the casement frame 1. With respect to the window frame 5, an especially advantageous heat insulation characteristic of the window frame 5 is achieved by the combination of the foam material 8 with the reinforcement profile 12 made of steel, on the other hand an excellent mechanical stability and protection against burglary and the like is achieved.

Likewise, the reinforcement profile 12 can serve as an isothermal guide element.

Furthermore, the steel profile part 12 can possibly be supported on projections 14.

The interior chambers 7a and 7c of the casement frame 1 and the interior chambers 11 a and lic of the window frame 5 are preferably foamed in situ with polyurethane, wherein preferably a polyurethane foam with a density of 30 to 40 kg/rn3 is used.

Such a foam with a A-value of approx. 0.021 to 0.031 allows the fulfilment of the passive house standards or the prerequisites for low-energy houses with a heat-transfer coefficient of < 0.8, wherein Uw designates the heat-transfer coefficient of the entire window including the casement frame 1, the window pane 2 and the window frame 5. Furthermore, a very light but mechanically highly stable window and/or frame profile for window or door frames and the like is created by the use of the polyurethane foam 8 and the reinforcement profiles 9 and 12, so that a less tight polyurethane foam with a specially high heat-transfer resistance can be used.

At the same time the design of the pre-charnbers 7b and 11 b allows that in these chambers a flowable medium 16 flows, particularly moves therein so that in the case of strong solar irradiation followed by heating of the exterior facade wall 18 and 20 of the pre-chambers 7b and 1 lb a heat discharge through the flow is ensured and thus the influence of heat conduction can be reduced.

In this manner a window system composed of window frame 5 and casement 1 is created in which by the provision of a flowable medium 16 in the pre-chambers 7b and lib of the profiled elements P a reduction of the influence of solar irradiation, particularly if the respective profiled elements P have a dark colour, can be managed. By the use of a reinforcement element 9, 12 on the one hand and the foaming of the interior chambers 7a, 7c and 11 a, 11 c of the profiled elements P by polyurethane foam of a relatively low density on the other hand, passive house suitable heat insulation properties can be ensured.

It is also of further advantage in this connection to use plastic hollow profile rails for the glass holding rails 4, which are foamed by polyurethane foam. Furthermore, profile rails of glass fibre reinforced plastic material or glass fibre reinforced press mats can also be used as reinforcement profiled elements 9, 12.

In the embodiment shown in Fig. 2 all interior chambers 7a, 7c and 11, lc are filled with a polyurethane foam 8 and the reinforcement elements 9 and 12 are made of steel. When using a polyurethane foam with a A-value of approx. 0.028, a Uf value of 0.927 W/m2K is reached, wherein Uf designates the heat-transfer coefficient of the frame system composed of casement frame and window frame 5.

In the embodiment shown in Fig. 3, some of the interior chambers 7a and 1 la are also filled by a polyurethane foam 8, whereas in casements 1 and window frames 5 two interior facade chambers 7c and 1 ic are free from polyurethane foam or other insulation materials. The reinforcement profiles 9 and 12 are also made of steel. When using a polyurethane foam 8 with a A-value of 0.028 in the interior chambers 7a and 1 la, a Uf value of 0.949 WIm2K is reached.

In the embodiment shown in Fig. 4, all interior chambers 7a, 7c and 1 la, 11 c are foamed by a polyurethane foam 8 having a A-value of 0.028. In contrast thereto, the reinforcement profiles 9 and 12 are made of glas fibre reinforced plastic material and the reinforcement element 12 of the window frame 5 is formed as a closed hollow profile. Here, a Uf value of 0.758 W/m2K is reached.

Finally, Fig. 5 shows an embodiment, in which in the casement 1 a reinforcement profile of glass fibre reinforced plastic material is inserted an a reinforcement profile 12 made of steel is inserted into the casement 5. Here, the reinforcement profile 12 of the window frame 5 is also formed as a closed hollow profile. All interior chambers 7a and 1 laa and interior facade chambers 7c and llc are foamed by a polyurethane foam 8 having a A-value of 0.028. A Uf value of 0.815 M/m2K is reached.

Fig. 6 shows a fifth embodiment. Contrary to the embodiments in Fig. 1 to 5, the venting openings 17 and 19 shown in Fig. 6 are formed on interior chamber walls, whereas the exterior façade walls of the profiled elements do not have venting openings. Accordingly a fluid communication between adjoining pre-chambers 7b and lib is achieved by the venting openings 17 and 19 according to Fig. 6. At least one of the venting openings 17 and 19 finally ensures a fluid communication with the atmosphere.

The invention is, of course, also applicable for door elements or other profiled elements to be inserted or inserted in exterior walls of buildings, e.g. in the field of prefabricated houses.
