Description

[0001] The present invention relates to a window, in particular a window with a swing-through sash and / or a roof window, a frame or lining, a window sash comprising a sash frame formed from several profile sections of a sash frame profile and a filling element received in the sash frame, wherein the sash frame profile has a groove extending longitudinally along its outer surface facing the frame; and a fitting by which the window sash is pivotably and / or pivotably mounted on the frame or lining, wherein the fitting comprises at least one pivoting element attached to a profile section of the sash frame profile.

[0002] A very simple window of this type and a fitting for it are known, for example, from EP 0 046 821 A1. A further development of this design is a window in which the sash can be rotated 180° within the frame. In such windows, the tilt or turn fittings are attached to the sashes at specific points in the center via centering holes and screws that engage in the window profiles. To ensure a secure fastening, it may be necessary, in the case of windows made of plastic profiles, to drive the fastening screws into the metal reinforcement embedded in an inner hollow chamber of the plastic profile. A disadvantage of this is that drilling through the plastic profile and simultaneously inserting the metal reinforcement requires high precision. Even slight deviations in the drilling for the fittings can lead to malfunctions when opening and closing such windows.

[0003] This is where the present invention comes in, which is based on the objective of providing a window, in particular a roof window, that at least partially overcomes the disadvantages of the prior art. In particular, the assembly of the fittings during the assembly of the window according to the invention should be simplified, thus ensuring the safe opening and closing of the window according to the invention.

[0004] These and other problems are solved according to the invention by a window having the features of claim 1. Preferred embodiments of the present invention are described in the dependent claims.

[0005] According to the present invention, it has been found that the hardware can be attached to the sash while maintaining the stability of the window by incorporating a hardware reinforcement element that is attached to the outside of the sash frame. This hardware reinforcement element partially assumes the function of attaching the hardware to the sash frame and also at least partially fulfills the function of the metal reinforcement embedded in the sash frame, thus allowing the sash frame to retain a high degree of its mechanical stability. According to the invention, this is achieved by providing the sash frame profile, whose profile sections form the sash frame, with a groove extending longitudinally along its outer surface facing the frame, and by engaging the hardware reinforcement element at least partially in this groove of the sash frame profile.

[0006] Accordingly, the present invention comprises a window, in particular a roof window, a frame or lining; a window sash comprising a sash frame formed from several profile sections of a sash frame profile and a filling element received in the sash frame, wherein the sash frame profile has a groove extending longitudinally along its outer surface facing the frame; and a fitting by which the window sash is pivotably and / or pivotably mounted on the frame or lining, wherein the fitting comprises at least one pivoting element attached to a profile section of the sash frame profile, wherein the window according to the invention is characterized in that the fitting comprises a fitting reinforcement element which is at least partially received in the groove on the outer surface of the sash frame.

[0007] In preferred embodiments of the window according to the invention, the hardware reinforcement element is clamped and / or fastened with fasteners, in particular screws, in the groove on the outside of the sash frame. This further increases the mechanical stability of the window according to the invention.

[0008] It can also be helpful if the hardware reinforcement element extends over at least 25% of the length of the profile section of the sash frame on which it is mounted. With such a length, sufficient stability of the resulting window sash is achieved, while the hardware reinforcement element can be easily inserted into the groove on the outside of the sash frame. To further increase the stability of the resulting window sash, it may be preferable for the hardware reinforcement element to extend over at least 30% of the length of the profile section of the sash frame on which it is mounted, in particular at least 35% of the length of the profile section of the sash frame, and most preferably at least 45% of the length of the profile section of the sash frame on which it is mounted.In particularly preferred embodiments of the window according to the invention, the hardware reinforcement element extends over at least 50% of the length of the profile section of the sash frame on which the hardware reinforcement element is arranged.

[0009] It can also be advantageous if the groove on the outside of the sash frame has height ranges between which at least one recessed area is arranged, wherein the hardware reinforcement element engages at least partially in the at least one recessed area of ​​the groove. This also contributes significantly to the mechanical stability of the window according to the invention.

[0010] In preferred embodiments of the window according to the invention, the sash frame profile is designed as a hollow plastic profile. Plastic windows require increased stability through reinforcing elements: The hardware reinforcement element used according to the invention can contribute to this or at least partially replace the reinforcement incorporated into the reinforcement chamber of plastic windows. A window frame can be obtained by welding mitered pieces of such a hollow plastic profile together. In alternative embodiments, the present invention is also applicable to other types of profiles, for example, aluminum-plastic composite profiles, wood-plastic composite profiles, and the like.

[0011] It is advantageous if the plastic of the sash frame profile comprises reinforcing fibers, in particular glass fibers. Such fiber-reinforced plastics, especially fiber-reinforced thermoplastics, possess a particularly high modulus of elasticity, which further contributes to the high mechanical stability of the window according to the invention. Thus, windows according to the invention can be used as plastic windows even without the use of additional reinforcing profiles. Glass fibers are preferably used as reinforcing fibers. Alternatively, organic fibers based on polymers, in particular PAN (polyacrylonitrile), carbon fibers, or natural fibers such as hemp or sisal can also be used. The proportion of reinforcing fibers in the thermoplastic is at most 50 parts by weight, preferably at most 25 parts by weight due to better weldability, more preferably at most 20 parts by weight, and even more preferably at most 15 parts by weight.-parts, each based on 100 parts by weight of the plastic material in the wing profile. Such a proportion of reinforcing fibers still allows for sufficiently good weldability of the material. Preferably, the maximum length of the reinforcing fibers is about 10 mm, particularly about 5 mm, and preferably about 1.5 mm. Such fiber lengths have proven particularly suitable for providing a co-extrudable fiber-reinforced plastic component that, after curing, results in a stable reinforcement component. A mean fiber length of 0.1 mm to 3 mm, particularly from 0.3 mm to 1.5 mm, and preferably from 0.4 mm to 0.6 mm, particularly about 0.5 mm, has proven particularly advantageous in this context.

[0012] The plastic material for the wing profile is preferably PVC, in particular rigid PVC (PVC-U) or post-chlorinated PVC (PVC-C) and mixtures thereof.

[0013] Additionally or alternatively, it can prove advantageous to insert at least one insulating element into at least one of the hollow chambers of the sash frame profile, the surface of which is coated at least partially with a low-emissivity metal layer. Such an insulating element significantly improves the thermal properties of the window according to the invention. Preferably, the insulating element is designed as a plastic profile. The coating of the insulating element can have a plurality of discontinuities. Such a coating, designed as a low-emissivity metal layer, can be formed as a metal layer applied to at least one side. Such an insulating element, while exhibiting high transmittance in the visible range of the electromagnetic spectrum, possesses high reflectivity in the infrared spectral range and thus exhibits low emissivity ("low E").Accordingly, such an insulating element has the effect of reducing the emissivity in the wavelength range from 3 µm to 50 µm, particularly in the region of maximum thermal radiation at room temperature (approximately 10 µm). This allows the insulating element to act as a good reflector for thermal radiation at room temperature and to be effectively used in hollow chamber profiles to improve thermal insulation. For this purpose, a metal layer, for example, an aluminum, silver, gold, and / or copper layer, is applied to at least one side of the insulating element to generate the high reflection in the infrared spectral range. The metal layer can have a thickness in the range of 5 nm to 200 µm, preferably in the range of 10 nm to 80 nm, and particularly preferably in the range of 35 nm to 60 nm.The metal layers are preferably coated with a protective layer (especially with antioxidant properties), a decorative layer, a colored layer, a lacquer layer, a functional layer, or combinations of these layers in one or more layers. This allows for good thermal insulation of the hollow chamber profile even with a limited number of hollow chambers. Furthermore, the material usage remains moderate when the number of hollow chambers into which such an insulating element is inserted is kept to a minimum. The insulating element(s) are inserted, particularly by sliding, into the corresponding hollow chambers after the hollow chamber profile has been extruded.

[0014] The hollow chamber profile according to the invention can advantageously be produced by an extrusion process known per se. Polyvinyl chloride (PVC), in particular rigid PVC (PVC-U) or post-chlorinated PVC, is preferred as the material for the hollow chamber profile. The material can preferably also be fiber-reinforced, in particular glass fiber-reinforced. An insulating element is inserted into each of the desired hollow chambers of the hollow chamber profile by means of insertion. The material of the insulating element is selected such that it does not interfere with the welding of profile sections made from the hollow chamber profile. Therefore, polyvinyl chloride (PVC), in particular rigid PVC (PVC-U) or post-chlorinated PVC, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), acrylonitrile butadiene styrene (ABS), as well as copolymers and blends of the aforementioned polymer materials are particularly suitable as plastic materials for the metallized plastic film.The insulating elements are preferably obtained by extruding the plastic core and subsequently coating the resulting profile on one or both sides with the metal, in particular with aluminum, silver, gold, and / or copper. Any material weakening that allows the insulating elements to be geometrically adapted to the geometry of the hollow chamber into which they are to be inserted is preferably introduced into the plastic film before or after vapor deposition with the metal.

[0015] In preferred embodiments of the hollow chamber profile according to the invention, the at least one insulating element is designed as a plastic profile provided with a metal layer on at least one side. It is particularly preferred if the at least one insulating element is designed as a plastic profile provided with a metal layer on both sides. In this way, the thermal insulation properties of the hollow chamber profile can be further improved. The metal layer(s) can have a thickness in the range of 5 nm to 200 µm, preferably in the range of 10 nm to 25 nm. The metal layers on both sides of the plastic film can be the same or different.

[0016] Furthermore, different insulating elements of a hollow chamber profile according to the invention can be provided with a metal layer on one or both sides.

[0017] Additionally or alternatively, the insulating element preferably has a material thickness of no more than 1 mm, particularly preferably in a range of 100 µm to 800 µm, and especially in a range of 200 µm to 600 µm. Such a thickness of the plastic film offers sufficient stability with a significantly reduced material requirement compared to corresponding internal webs of the hollow chamber profile.

[0018] It can also be helpful if the hardware reinforcement element is attached to the sash frame by at least one fastener, in particular at least one fastening screw, which engages in a fastening channel of the sash frame profile running perpendicular to the groove. Driving the fastener into such a fastening channel ensures sufficient pull-out forces, so that driving the fastener into a metal wall, e.g., any existing metal reinforcement, is not necessary. Plastic hollow chamber profiles with such fastening channels are known, for example, from DE 20 2006 016 165 U1, to which explicit reference is hereby made with regard to the design and manufacture of plastic hollow chamber profiles with fastening channels.

[0019] It can also be useful if the hardware reinforcement element (33) is at least partially concealed to the outside by a cover profile.

[0020] The window according to the invention can be manufactured row by row or layer by layer using a row-based or layer-based manufacturing process (e.g. 3D printing), but it is preferred to produce the profiles by extrusion or co-extrusion and to weld miter-cut pieces to form frames.

[0021] The present invention will now be explained in detail with reference to the embodiments illustrated in the figures. Figure 1 is a schematic cross-sectional view of a window according to an embodiment of the present invention; and Figure 2 is a schematic partial side view of the window. Fig. 1 shown window according to the invention.

[0022] In Figure 1 An embodiment of the window 1 according to the invention is shown in a cross-sectional view. According to the Figure 1In the embodiment shown, the window 1 according to the invention comprises a frame 2 or alternatively a lining, a fitting 3 and a window sash 4.

[0023] The window sash 4 comprises a sash frame 42 formed from several profile sections of a sash frame profile 41, into which a filling element 43 is received. The filling element 3 is in the Figure 1 The embodiment of the window 1 according to the invention shown is designed as a schematically depicted insulating glazing, in particular as triple-pane insulating glazing. The sash frame profile 41 is shown in the Fig. 1 The embodiment shown is designed as a plastic hollow chamber profile, to the weather-side outer wall of which a cover shell 44, in particular made of aluminium, is snapped in place.

[0024] According to this embodiment of the window 1 according to the invention, the frame 2 is composed of several profile sections of a frame profile 21. The frame profile 21 is also designed as a hollow chamber plastic profile, to whose weather-facing outer wall a cover shell 24, in particular made of aluminum, is snapped in place.

[0025] The hollow plastic profile of both the frame 2 and the sash 42 is made of a thermoplastic polymer material, preferably polyvinyl chloride (PVC), in particular rigid PVC (PVC-U) or glass fiber reinforced PVC, to which additives such as stabilizers, plasticizers, pigments, and the like are added. It is composed of a multitude of hollow chambers, each surrounded by inner walls and partially also by outer walls of the hollow plastic profile.

[0026] The sash profile has a groove 44 extending longitudinally along its outer surface facing the frame 2. On the inner surface of the profile opposite the groove 44, the sash profile includes a fastening channel 45. External elements can be attached to the sash profile by driving suitable fasteners, such as screws, into the fastening channel 45. A fitting 3 is arranged in the gap between the sash 42 and the frame 2. The fitting 3 allows the window sash 4 to be pivotally and / or tiltably mounted on the frame 2.

[0027] As from Fig. 2As can be seen, the fitting 3 comprises a pivot element 31, which is attached to the sash frame 42, fitting arms 32, 32', 32" which are each connected to one another via hinges, and a mounting arm (not shown) by means of which the fitting 3 is attached to the frame 2 by means of appropriate fasteners. Furthermore, the fitting 3 also comprises a fitting reinforcement element 33. In this embodiment, the fitting reinforcement element 33 is designed as an elongated element made of metal, in particular steel, which is obtained by roll forming a corresponding sheet. The fitting reinforcement element 33 is rotatably mounted about the pivot element 31.

[0028] To attach the fitting 3 to a fastening element (not shown), in particular a fastening screw, it is guided through the rotating element 31 and driven into the fastening channel 45 of the sash frame profile. Furthermore, the fitting reinforcement element 33 is clamped in the groove 44 of the sash frame profile along its entire length and additionally screwed to it. The groove has a recessed area 46 into which the fitting reinforcement element 33 engages. In the adjacent vertical areas, the fitting reinforcement element 33 rests on the vertical surfaces.

[0029] According to the in Fig. 1 In the illustrated embodiment of the window 1 according to the invention, the hardware reinforcement element 33 is concealed on the outside by a cover profile 5. The cover profile is snap-fitted to the sash profile via corresponding receptacles. This contributes to the appearance of the window 1 according to the invention. In the illustration according to Fig. 2The cover profile 5 is missing to make the hardware reinforcement element 33 visible on the sash frame 42.
