Abstract
Description
Technical field
[0001] The invention relates to a modular thermal insulation device for sealing and insulating windows, doors, or similar building elements installed in wall or building openings. The thermal insulation device provides additional insulation, particularly during the colder months, in the area of windows and doors of a building. State of the art
[0002] It is well known that buildings lose a significant amount of heat, especially through windows and doors, during the colder months, particularly in winter, as the thermal insulation of doors and windows is generally inferior to that of the building structure. This heat loss results in a considerably higher energy requirement for heating the rooms. These heat losses pose a major problem in buildings, not only due to rising heating costs but also from an environmental perspective. Heat loss is particularly pronounced in older windows, especially single- or double-glazed windows or those with wooden frames, as these neither meet current thermal insulation standards nor are energy-efficient.
[0003] Another problem is that windows are subject to a natural wear and tear process, which means that older windows are inherently less airtight. Besides age, the materials and construction of the windows are also crucial for their lifespan. Wooden window frames weather and warp over time, while aluminum and PVC windows can shift due to gravity. Porous seals on the window frames are another common cause of leaky windows. Furthermore, cracks and gaps between the window and the masonry also lead to heat loss. This leakage often creates drafts, which are perceived as very unpleasant.
[0004] Insulating or thermal films, also known as cold-protection films for windows, are already well-known. These are applied or glued directly to the interior surface of the window pane. The cold-protection film adhered to the window surface reflects heat radiation and prevents it from escaping to the outside. Consequently, the heat remains in the room for longer. While the cold-protection film reduces energy loss through the window pane, it does not cover the window frame, the area between the wall and the window, or the window reveal. Therefore, such self-adhesive cold-protection films only reduce heat loss to a limited extent.
[0005] Furthermore, thermal roller blinds that can be mounted on windows are known. These serve, on the one hand, to protect the room from excessive heat from sunlight on warm summer days, and on the other hand, to ensure that heat remains in the room during the winter months or the cooler seasons, instead of escaping. Typical thermal roller blinds have a silver coating on the back or the outward-facing side of the blind. This silver coating reflects sunlight and prevents it from penetrating the room. Conversely, warm room air does not cool down too much because it is not directed across the cold window pane. In this case, the thermal roller blind acts as a kind of barrier. A disadvantage is that the silver coating makes thermal roller blinds opaque.Furthermore, thermal roller blinds do not have side sealing elements or sealing elements at the bottom edge, which means that room air can flow into the space between the thermal roller blind and the window panes, especially from the sides and / or from below.
[0006] German patent application DE 20 2011 104 508 U1 describes a heat-insulating window with a removable window frame and integrated heat-insulating film. The window frame consists of upper and lower mounting rails and side frame members and is clamped to the exterior wall of the building between the windowsill and the lintel using spring tension. The window frame can be assembled using dowels and is dimensioned to extend beyond the window reveal and cover the wall opening. The heat-insulating film is designed as a film with enclosed air cushions or bubbles and is attached to the upper and lower mounting rails of the window frame. Disadvantages include the suspension of the thin heat-insulating film in the mounting rails and the lack of a seal against the wall, windowsill, and lintel. Furthermore, the film with enclosed air cushions reduces the heat transfer coefficient.Air bubbles prevent a clear view through the heat-insulating film to the outside.
[0007] Furthermore, DE 31 08 796 C2 discloses a device for sealing windows or doors installed in wall openings, comprising at least one material web section made of a thin, crystal-clear plastic film, an upper horizontal rail in which the material web section is suspended for linear slidability, and two vertical rails designed as stepped rails, which are attached directly adjacent to the two vertical edges of the wall opening, wherein the first step forms a first, inner fastening section for attaching a first material web section and the second step forms a second, outer fastening section for attaching a second material web section. The material web section is attached to the fastening section by means of a hook-and-loop fastener.Furthermore, the device either has a horizontally running bottom rail or the material web is equipped with a hem at its lower edge, into which a lead chain is inserted. A disadvantage here is that the production of the material web is costly and extremely complex, since, firstly, reinforcement must be attached to the upper end to prevent the thin material web from tearing when suspended from the horizontal rail, and secondly, hook-and-loop fasteners must be attached to the respective long sides. Depending on the design, the lower edge of the material web must also be designed as a hem. In addition to the complex production of the material web, hook-and-loop fasteners do not provide good sealing properties.
[0008] Finally, DE 26 21 254 A1 relates to an additional frame, covered with a transparent film, that can be inserted into the interior of the window opening. The frame consists of vertical and horizontal frame sections connected at their corners. It is inserted into the window opening between the windowsill and the lintel and rests against the vertical surfaces of the window opening, the so-called window reveal, with a seal in each case. A snap-fit or clamping connection secures the frame to the window frame. The transparent film is attached to the frame, preferably to the vertical frame sections, by means of an additional clamping strip. A disadvantage is the requirement for precise adjustment of the frame sections and the associated seals to the dimensions of the respective window reveal. Description of the invention
[0009] The object of the present invention is therefore to provide a device that overcomes the disadvantages of the prior art. The device should ensure the best possible and most efficient thermal insulation, positively influence the room temperature and / or climate throughout the year, and be easy to install and simple and inexpensive to manufacture. This object is achieved according to the invention by the modular thermal insulation device according to independent claim 1. Further advantageous aspects, details, and embodiments of the invention will become apparent from the dependent claims, the description, and the drawings.
[0010] The present invention provides a modular thermal insulation device for sealing windows, doors, or similar building elements installed in wall or building openings. The device comprises a mounting frame, which can be mounted on the interior side of the wall or masonry of the building and at least partially surrounds the wall or building opening, and a transparent film that seals the wall or building opening. The film is stretched by means of the mounting frame and held along the wall or building opening. The mounting frame includes at least one elongated sealing element for sealing the mounting frame against the wall or building opening, which is arranged between the wall of the building and the mounting frame. In a preferred embodiment, the sealing element is designed in the form of a brush seal.
[0011] The major advantage of the thermal insulation device according to the invention lies in the fact that the thermal insulation device is not inserted into the wall or building openings or even attached to the window or door frame, but is mounted on the interior masonry surrounding the wall or building openings. In other words, the thermal insulation device is designed to extend beyond the wall or building openings, so that the mounting frame can be attached to the interior masonry or the inner wall of the building. Accordingly, the thermal insulation device protects the wall or building openings from heat loss.
[0012] The building opening is completely covered. This eliminates the need for precise adjustment of the frame elements to the interior dimensions of the opening. Once installed, the thermal insulation device creates an air space or chamber between the window and the building interior, which acts as a thermal insulator, insulation layer, or insulation chamber. Attaching the thermal insulation device to the interior masonry creates a particularly large insulation space, as essentially the entire depth of the reveal, especially the door or window reveal, is utilized. The larger the air-filled insulation space between the window or door and the thermal insulation device, the better the thermal insulation properties and the lower the energy and heat losses through the windows or doors.Energy losses through doors and windows can be reduced by up to 30% using the thermal insulation device according to the invention, compared to doors and windows without this thermal insulation device. Improved thermal insulation of windows and / or doors also leads to significantly lower energy costs and, in some cases, substantial savings on heating costs.
[0013] Not only is the improved thermal insulation of windows, doors, and similar building elements a major advantage, but the drafts that regularly occur due to leaks around windows or doors can also be significantly reduced. Many people find drafts around windows and doors unpleasant and bothersome. These drafts often arise because windows or doors warp over the years, or because cracks or gaps appear in the masonry of the wall or building opening, such as cracks in the window reveal, lintel, or sill. Cracks or gaps can also occur along the expanding foam strips that are installed between the window or door frame and the masonry for sealing and thermal insulation.Furthermore, swelling tapes or pastes can swell to varying degrees during the installation of windows and doors, which can lead to significant variations or fluctuations in the insulation or thermal insulation properties along a swelling tape.
[0014] The modular thermal insulation device now comprises a circumferential seal, which is realized by at least one elongated sealing element, preferably by several sealing elements. Preferably, each part of the mounting frame, such as the individual frame parts or the roller shutter box-like retaining device, has a separate elongated sealing element, wherein the elongated sealing elements serve to seal the mounting frame against the wall or building opening; that is, the elongated sealing elements rest on the masonry surrounding the wall or building opening when the thermal insulation device is installed.
[0015] The elongated sealing element is particularly preferred in the form of a brush seal. A brush seal is a contact seal comprising a carrier element, such as a sealing body, head, or strip, and a multitude of thin wires or fibers attached to the carrier element. The seal, consisting of numerous wires or fibers, adapts itself to the surface to be sealed. The use of a brush seal as an elongated sealing element has the advantage that it achieves a good seal between the mounting frame and the masonry, even with unevenness on the surface of the masonry and / or sloping walls, as is often the case in older buildings. Thus, the brush seal prevents the water from escaping from the masonry surface.The building opening reduces drafts flowing towards the interior of the building to a minimum, while on the other hand a particularly well-sealed insulation space is provided.
[0016] Particularly preferred is the transparent film being at least partially, and preferably completely, coated with a layer to shield against UV rays. The film coated in this way has a light transmittance of less than 5%, and in particular less than 1%, in the ultraviolet or UV range. The transparent film with UV coating thus offers strong protection against premature fading of objects located in buildings, especially furnishings such as carpets, furniture, or pictures, etc., or textiles such as curtains, clothing, etc. Consequently, these objects can be exposed to sunlight for significantly longer periods before the first signs of fading appear.
[0017] A further advantage is that the transparent film has a light transmittance in the visible range that is greater than 70%, preferably greater than 80%, and particularly greater than 85%. Consequently, despite the UV coating, the film is crystal clear and ensures distortion-free visibility to the outside.
[0018] Another advantage is that the transparent film is extremely thin, with a thickness of only between 0.001 mm and 1 mm, preferably between 0.003 mm and 0.1 mm. Depending on the intended use, the transparent film can be single- or multi-layered, particularly two- or three-layered. Since the thermal insulation device is used inside the building and not on its exterior, the transparent film does not need to withstand particular environmental influences such as rain, snow, wind, or even strong gusts of wind or storms. Consequently, an extremely thin film can be selected, which is stretched across the mounting frame.
[0019] In a first, particularly advantageous embodiment, the mounting frame is designed as a type of tension frame and covered with the transparent film. For this purpose, each individual frame part has a groove-shaped, second receiving section in which the transparent film is held by means of a clamping device, such as a keder or keder strip. To cover the mounting frame, the transparent film is first inserted into the groove of the second receiving section before the keder strip is pressed into the groove. The transparent film is thus clamped to the mounting frame. A keder roller or keder press is particularly suitable as an aid for pressing the keder strip into the groove of the second receiving section. By releasing or pulling the keder strip out of the groove, the transparent film can be removed and, if necessary, replaced.This allows damaged or perforated foils to be easily exchanged and replaced. The replaceability of the foil also ensures a sustainable thermal insulation system.
[0020] The mounting frame preferably comprises several frame parts. Most notably, the mounting frame has four frame parts connected at their corners to form a stable, closed frame. For example, the mounting frame has a first side frame part, a second side frame part opposite the first, a third frame part connecting the first and second side frame parts at their upper ends, and a fourth frame part connecting the first and second frame parts at their lower ends, with the first through fourth frame parts forming a preferably closed mounting frame. In other words, in this embodiment, the mounting frame consists of two vertically extending frame parts and two transversely extending frame parts. All of the frame parts are located at the edge of the masonry, which forms the wall or...
[0021] The frame is mounted around or adjacent to the building opening. It is also conceivable that the frame components can be individually adapted to the size and / or width of the wall or building opening.
[0022] The frame components can be made of plastic, wood, or metal, especially aluminum or stainless steel. Plastic and aluminum frame components are particularly easy and cost-effective to manufacture. Frame components made of extruded aluminum are especially advantageous. This not only results in very low weight but also provides high stability and durability.
[0023] Preferably, the frame parts are designed in the form of frame profile elements or frame hollow profile elements, wherein each of the frame profile elements or frame hollow profile elements has at least a first receiving section along its longitudinal extent for receiving and fastening elongated sealing elements, in particular brush seals, and at least a second receiving section for receiving and fixing and / or guiding the transparent film.
[0024] In a first embodiment, each frame profile element has a bearing surface facing the masonry and a top or visible side opposite this, as well as two spaced-apart, groove-shaped receiving sections: a first receiving section into which the brush seal can be pressed and detachably fastened, and a second receiving section into which the transparent film can be detachably fastened. The film and / or the brush seal is detachably fastened in the respective receiving section by means of a keder and / or clamp connection. Alternatively, both the film and the brush seal can be fastened with adhesive or, preferably, double-sided adhesive tape. In particular, the brush seal can be designed as a self-adhesive brush seal so that its adhesive surface can be fastened directly in the groove-shaped opening of the first receiving section.
[0025] To achieve the best possible seal between the mounting frame and the masonry, the mounting frame is designed such that, in its assembled state, it has at least one primary, circumferential, groove-shaped opening for attaching the brush seal and at least one secondary, circumferential, groove-shaped opening for attaching the foil. Depending on the brush seal's installation, it can be a single piece, for example, a brush sealing strip that is pressed into the fully assembled mounting frame. Alternatively, multiple sealing elements or brush seals can be provided, so that, for example, each frame section is equipped with a separate brush seal. The brush seal's detachable fastening allows it to be easily replaced at any time.In general, the advantage of modular thermal insulation systems is that defective and / or worn and / or damaged components, such as brush seals, transparent film, frame parts, corner connectors, etc., can be easily exchanged and replaced.
[0026] In a further alternative embodiment, a roller shutter box-like holding device with at least one shaft for rolling up and down the transparent film is provided. This holding device can be located either in the upper or lower region of the thermal insulation device or in the side region of the thermal insulation device. Depending on the embodiment, the holding device thus replaces either the upper or third frame section, the lower or fourth frame section of the mounting frame, or one of the two side frame sections. Preferably, the holding device is located at the top, i.e., in the area of the window lintel, so that the user simply pulls the transparent film downwards, i.e., towards the windowsill, when using it. The film can therefore be rolled up and unrolled from the holding device like a roller blind.The shaft of the roller shutter-like holding device can be driven manually or by a drive such as an electric motor, stepper motor, or similar drive. A control unit can also be provided to control the drive. This control unit can include a timer configured so that the film is automatically rolled up or down by the shaft depending on the time of day.
[0027] To ensure the transparent film is guided during winding and unwinding, the side frame sections, namely the first and second frame sections, each have a lateral guide groove facing the transparent film. This guide groove extends essentially the entire length of each frame section, so that when extended, the film completely covers the wall or building opening. The guide groove on the first and second frame sections thus serves to guide and securely hold the transparent film laterally during winding and unwinding.
[0028] A coupling element can be arranged at the free end of the transparent film to allow the film, when fully extended or in its end position, to be hooked or attached to the lower, fourth frame member or to a bracket or counter-coupling element in the area of the windowsill. It is conceivable that the coupling element at the lower edge of the film is magnetic or magnetizable, and that the lower, fourth frame member is also magnetic or magnetizable. In this way, the coupling element can be detachably attached to the lower, fourth frame member using magnetic means. In an alternative embodiment, the connection between the coupling element and the area on the windowsill and / or the lower, fourth frame member is made by means of at least one eyelet / loop and at least one hook, clamp, snap, or click connection.
[0029] Furthermore, the roller shutter box-like retaining device has at least one spring element, wherein the spring element is operatively connected to the shaft in such a way that the spring element is tensioned when the film is unwound and can be driven by the restoring force of the spring element generated when the transparent film is unwound when the film is wound up. The restoring force of the at least one spring element causes the film to be automatically wound back up onto the shaft as soon as the coupling element is released from the lower, fourth frame part or the corresponding holder or counter-feedback element by the user. Thus, the film, which can be automatically wound onto the shaft, provides a particularly user-friendly thermal insulation device. In addition, the film is securely stored in the wound state, and the window or door remains freely accessible. This is especially advantageous when ventilating or...To open the door or window, it is necessary that the foil can be easily rolled up or removed from the wall or building opening.
[0030] The frame components are connected to each other and / or to the roller shutter box-shaped mounting device at their respective adjacent end faces by means of a form-fit, force-fit, or magnetic connection. Preferably, tongue-and-groove joints, dovetail joints, screw connections, magnetic connections, or angled corner connectors or corner plates are used as connection types or means. Specifically, the corner connector can have a first, groove-shaped receiving section for attaching the brush seal and a second, groove-shaped receiving section for attaching the foil. In an advantageous embodiment, the mounting frame consists of four frame components and four corner connectors, with the corner connectors serving to join the corresponding frame components.
[0031] To mount the modular thermal insulation system to the masonry or wall of the building, several fastening devices are provided for attaching the mounting frame. These devices can include mounting brackets, which are attached to the masonry or wall using adhesive, double-sided tape, screws, etc. The mounting brackets typically have at least one clamping screw, which secures the mounting frame to the bracket.
[0032] Optionally, the fastening devices are designed as snap-in or click connectors. These snap-in or click connectors are two-part, with one connecting part attached to the masonry and the other to the mounting frame. Preferably, the snap-in or click connector is made of metal for durability and robustness.
[0033] In yet another alternative embodiment, the fastening devices are designed as magnetic or magnetizable fasteners. Here, for example, a magnetizable first connecting element, such as a magnetizable plate and / or screw, is attached to the masonry. To allow the mounting frame to be detachably attached to this, the mounting frame, particularly the frame components and / or corner connectors, has corresponding magnetic second connecting elements, such as a magnetic plate or a magnetic coating. Conversely, the first connecting elements on the masonry can also be magnetic, and the second connecting elements on the frame components and / or corner connectors can be magnetizable. Especially with magnetic fastening devices, as well as with snap or click connectors, each first connecting element on the masonry is associated with a second connecting element on the mounting frame.
[0034] No special tools are required for mounting the modular thermal insulation system to the masonry or wall. Therefore, installation is extremely simple. Attaching the modular thermal insulation system to the interior of the building also offers further advantages. Above all, for tenants who are only permitted to make alterations to the facade or exterior of the building under certain conditions, the thermal insulation systems, which can be attached to the inside of windows and doors, represent a particularly simple way to reduce energy and heat loss through windows and doors. Similarly, in listed buildings, structural measures and / or alterations to the facade or exterior of the building cannot be carried out without further ado. In contrast, the thermal insulation system according to the invention can be easily installed on the interior of the building, as no restrictions need to be met.
[0035] For the thermal insulation of a wide window or even a wide window front, several thermal insulation devices can be used, arranged adjacent to or directly next to each other to completely cover the wide wall or building opening. For example, two or more thermal insulation devices can be arranged directly next to each other. With two thermal insulation devices, the second frame section of the first mounting frame abuts directly against the first frame section of the second mounting frame. The wider the window or window front, the more thermal insulation devices can be arranged side by side.
[0036] Further developments, advantages, and possible applications of the invention will also become apparent from the following description of exemplary embodiments and from the figures. All features described and / or illustrated are, individually or in any combination, fundamentally the subject matter of the invention, irrespective of their compilation in the claims or their cross-reference. Brief description of the drawings
[0037] The invention will be explained in more detail below with reference to exemplary embodiments in conjunction with the drawings. The drawings show... Fig. 1 a perspective view of a modular thermal insulation device according to the invention for sealing windows, doors or similar building elements inserted in wall or building openings; Fig. 2 a perspective view of a fastening device in the form of a mounting bracket; Fig. 3 a perspective side view of the thermal insulation device according to the invention Fig. 1; Fig. 4 A detailed view from the rear of two adjacent mounting frames for covering a large building opening and Fig. 5 a perspective view of an alternative embodiment of the modular thermal insulation device according to the invention for sealing windows, doors or similar building elements inserted in wall or building openings with a roller shutter box-shaped holding device. Ways to implement the invention
[0038] Fig. Figure 1, referenced by numeral 10, shows a modular thermal insulation device for sealing windows, doors, or similar building elements installed in wall or building openings 12. While the masonry of a building generally has good insulating properties, windows, especially those with inefficient single glazing, have an extremely low insulation value. The modular thermal insulation device according to the invention serves to mount the mounting frame, which carries or covers the transparent film, to the masonry surrounding the building opening. This creates an air space or chamber between the window and the actual interior of the building, with the enclosed air acting as a thermal insulator. The air-filled air space or chamber interrupts the heat flow that is directed from the inside to the outside during the cold season, since both the special transparent film and the air-filled air space or chamber act as thermal insulators.The air chamber has poor thermal conductivity properties.
[0039] The modular thermal insulation device 10 can be mounted on the interior side of the building wall. The thermal insulation device 10 consists of a mounting frame 20, which at least partially, and preferably completely, surrounds the wall or building opening 12. The wall or building opening 12 is generally a penetration in the masonry into which a door or window is inserted to close the wall or building opening 12. If a window is inserted into the wall or building opening 12, the vertical surfaces created in the masonry by the installation of the wall or building opening 12 are referred to as the reveal or window reveal, the upper surface as the lintel, and the lower surface as the window sill. The wall or building opening 12 is surrounded on all sides by the masonry. The thermal insulation device 10 is not inserted into the wall or building opening, but is attached to the wall or building opening 12.The thermal insulation device 10 is attached to the perimeter of the building opening 12. By attaching it to the building's masonry, a very large space is provided between the thermal insulation device 10 and the window or door, with the space extending over the entire depth t of the reveal or window reveal. Thus, the size of the insulation space depends significantly on the thickness of the masonry. Compared to conventional thermal insulation devices, which are arranged directly on the window frame, the thermal insulation device according to the invention now provides a significantly larger space or insulation space.
[0040] Furthermore, the modular thermal insulation device 10 has a transparent film 30 that closes the wall or building opening 12 and is held on or stretched by the mounting frame 20. Fig. Figure 1 shows a mounting frame 20 in which the film 30 is clamped and held along the wall or building opening 12. The film 30 is a transparent film, in particular a clear film. Preferably, the film 30 is provided with a coating for shielding against UV rays, especially UV-A and UV-B rays. A film 30 with a UV coating serves, on the one hand, as protection against fading for valuable furniture and textiles, and additionally offers good heat protection and protects against aggressive UV radiation. Despite the UV coating, the film 30 is still crystal clear, and the film preferably has a light transmittance in the visible range that is greater than 70%, preferably greater than 80%, and in particular greater than 85%. In contrast, the light transmittance of the film 30 in the ultraviolet range, i.e., in the UV range, is less than 5%, and in particular less than 1%.
[0041] Furthermore, the film 30 is an extremely thin, yet tear-resistant film. Preferably, the thickness d of the film 30 is between 0.001 mm and 1 mm, more preferably between 0.003 mm and 0.1 mm.
[0042] Furthermore, the mounting frame 20 includes at least one elongated sealing element 40, which seals the mounting frame 20 against the wall or building opening 12. To achieve the most effective seal possible, a brush seal is used as the elongated sealing element 40. A brush seal is characterized by its ability to seal extremely well even against uneven surfaces and / or sloping walls due to its special design. The brush seal consists of a carrier element, such as a sealing body, head, or strip, and a multitude of thin wires or fibers attached to the carrier element. Fig. Figure 3 shows a brush seal which is inserted into the receiving section provided on the mounting frame. The brush seal thus seals between the mounting frame 20 and the masonry or wall, creating a closed, air-filled space between the window / door frame and the thermal insulation device 10. This air-filled space serves as an insulation chamber. Due to its low thermal conductivity, the air enclosed in the insulation chamber acts as an insulator and prevents heat from being rapidly lost to the outside through the window. Therefore, the larger the insulation chamber, the greater the volume of air it contains, and the better the insulation against the cold.
[0043] As in the exemplary embodiment according to Fig. As shown in Figure 1, the mounting frame 20 has several frame parts 21, 22, 23, 24 which are connected to form a closed frame by means of suitable connecting means. The closed mounting frame 20 in Fig. The assembly comprises a first lateral frame part 21, a second lateral frame part 22 opposite the first lateral frame part 21, a third frame part 23 connecting the first and second lateral frame parts 21 and 22 at their upper ends, and a fourth frame part 24 connecting the first and second frame parts 21 and 22 at their lower ends. When assembled, the four frame parts 21, 22, 23, and 24 form a closed and stable frame. The frame parts 21, 22, 23, and 24 surround the wall or building opening 12 and are mounted to the masonry. Preferably, the mounting frame is designed as a type of cover or tension frame. The frame parts 21, 22, 23, and 24 are preferably made of plastic, wood, or metal, in particular aluminum or stainless steel.
[0044] To enable the seal to be attached to the mounting frame 20 and the transparent film 30 to be fastened to the mounting frame 20, the frame parts 21, 22, 23, 24 are designed as frame profile elements or hollow frame profile elements. For fastening the brush seal, at least one first, groove-shaped receiving section 26 is provided on each frame profile element, the receiving section being open on the side facing the masonry. The first receiving section 26 of each frame part 21, 22, 23, 24 extends essentially over the entire length of the respective frame part and is designed such that the brush seal can be received and fastened within it.
[0045] In addition to the first receiving section 26, a second, groove-shaped receiving section 27 is provided, which is spaced apart from the first receiving section 26 and is inserted into the respective frame hollow profile element and serves to attach the transparent film 30 to the mounting frame 20. Fig. As can be seen in Figure 4, the first and second receiving sections 26, 27 are arranged apart from each other and run parallel to each other. The second receiving section 27 extends essentially over the entire length of the respective frame part and is designed such that the transparent film 30 can be received therein and preferably clamped in place.
[0046] The production of such frame profile elements or frame hollow profile elements is particularly simple and cost-effective using injection molding or extrusion.
[0047] The attachment of the film 30 to the mounting frame 20 is not shown in the figures. Advantageously, the film 30 is stretched over the assembled mounting frame 20, with the film ends 30 being placed in the respective groove of the second receiving section 27. Preferably, a keder or keder strip is used to clamp the film ends in the respective second receiving section 27. However, other fastening methods for attaching the film 30 are also conceivable. For example, the film 30 can also be attached to the respective second receiving section by means of an adhesive bond or double-sided adhesive tape. The film 30 can also have a self-adhesive edge strip.
[0048] Like the foil 30, the brush seal can also be attached to the respective first receiving section 26 by means of a clamping or adhesive connection. Self-adhesive brush seals can also be used, which can be attached to the first receiving section 26 in a particularly simple manner.
[0049] In Fig. Figure 4 shows a detailed view of two adjacent thermal insulation devices 10. Several thermal insulation devices 10 can be useful for covering wide windows or large window fronts. The two frame parts of a first thermal insulation device 10 and a second thermal insulation device 10 are directly adjacent to each other, with each thermal insulation device 10 having its own independent or separate brush seal. The respective frame parts 21, 24 of the first thermal insulation device 10 and the respective frame parts 22, 24 of the first thermal insulation device 10 are connected to each other at their buttresses or abutting end faces by means of a suitable connecting element, in particular a corner connector 28.Optionally, the adjacent end faces of the frame parts 21, 22, 23, 24 can be connected to each other by means of a form-fit and / or force-fit or magnetic connection, in particular by means of a tongue and groove connection, dovetail connection, screw connection and magnetic connection.
[0050] When the mounting frame 20 is assembled, the brush seal forms a circumferential seal, so that the insulating space between the window and the thermal insulation device is sealed as well as possible.
[0051] For mounting the thermal insulation device 10 on the masonry, fastening devices 60 are also provided, which can be designed in a variety of ways. Fig. Figure 2 shows, for example, a fastening device 60 in the form of a mounting bracket. The mounting bracket 60 is preferably attached to the wall using conventional screws. A corner of the mounting frame 20 is then positioned in the corresponding mounting bracket 60 and fixed to the mounting bracket 60 by means of at least one clamping screw. Alternatively, the fastening device 60 can be designed as a magnetic fastening device, namely with a magnetic first fastening element and a magnetic or magnetizable second fastening element that interacts with it, or vice versa.
[0052] In Fig.Figure 5 shows a corner connector 28, which has a magnetic first fastening element on its wall-facing surface. A magnetizable or magnetic fastening element (not shown) is associated with the corner connector 28 on the wall. The second fastening element located on the wall can be in the form of a screw, in particular a screw made of iron, or a magnetic or magnetizable retaining plate or plate. The corner connector 28 can also have a magnetic or magnetizable retaining plate or plate, or optionally a magnetic or magnetizable coating. Alternatively, the fastening devices 60 can also be designed as snap or click connectors.
[0053] In an alternative embodiment, the film 30 is not rigidly held in the mounting frame 20, but is arranged to move vertically. For this purpose, the mounting frame 20 has, instead of the upper or lower frame part 23, 24, a roller shutter box-like retaining device 50 with at least one shaft for rolling up or down the transparent film 30. Typically, the roller shutter box-like retaining device 50 is attached to the masonry, specifically at the upper edge of the wall or building opening 12. By attaching the roller shutter box-like retaining device 50 to the upper edge of the wall or building opening 12, the user can conveniently pull or unroll the film 30 downwards, i.e., towards the bottom of the window. Conversely, the window or door can be quickly made accessible to the user simply by rolling up the film 30.The mounting frame 20 therefore does not need to be removed from the wall to access the window or door. Access to windows or doors plays a particularly important role when ventilating rooms.
[0054] In this embodiment, the side frame members 21, 22 each have a guide groove in which the transparent film 30 is guided laterally and securely held during the winding and unwinding motion. The respective guide groove directs the film 30 from the starting position, in which the film 30 is completely wound onto the shaft, to an end position, in which the free end of the film 30 is fully extended or in which the free end of the film 30 seals against the lower frame member 24 or the windowsill. A coupling element 32 is preferably arranged at the free end of the film 30, which can, for example, be in the form of a retaining rail or a film hem. The coupling element 32 serves to hook or fix the film 30 to the lower, fourth frame member 24 or to a counter-coupling element in the area of the window sill.
[0055] It is conceivable that the coupling element 32 at the lower edge of the foil is magnetic or magnetizable, and that the lower, fourth frame part 24 is magnetic or magnetizable. In this way, the coupling element 32 can be detachably attached to the lower, fourth frame part 24 by means of magnetic means. In an alternative embodiment, the connection between the coupling element and the area on the windowsill and / or the lower, fourth frame part 24 is realized by means of at least one eyelet / loop and at least one hook, clamp, snap, or click connection.
