Description

[0001] The present invention relates to an insulating device for a building opening and to a method for insulating a building opening. The building opening can be realized, for example, by a window or a door, wherein the window has a window frame and, generally, a window sash with a pane of glass that is movable relative to the window frame, and the door has a door frame with a door leaf that is movable relative to the door frame.

[0002] Insulating devices for windows and doors are known from the prior art, which prevent the ingress of insects and / or pollen through the building opening when the sash is open. These insulating devices generally comprise a frame and a fabric or knitted material stretched across the frame, which is impermeable to insects and / or pollen, but allows air to pass through when the sash is open. The frame of these insulating devices is attached to the building frame in a suitable manner, particularly retroactively.

[0003] Against the background of the energy transition and the associated need to reduce the energy consumption of buildings, the present invention aims to provide an easily retrofittable insulation device that can be installed cost-effectively and easily by a user.

[0004] One possible solution to the problem is provided by an insulating device and a method for insulating a building opening, comprising the features of the respective independent claim. Further solutions and advantageous embodiments are specified in the dependent claims and in the following description, wherein individual features of the advantageous embodiments can be combined in a technically meaningful manner. The features disclosed with respect to the insulating device are applicable to the method and vice versa.

[0005] The problem is solved in particular by an insulating device for a building opening having a building frame, such as a window frame or door frame, and a sash, such as a window sash or door sash, wherein the insulating device has a frame and a surface structure attached to the frame, wherein the surface structure is airtight, so that in a mounted state of the insulating device on the building opening a thermally insulating space can be formed between the surface structure and the sash.

[0006] Accordingly, the invention relates to a door or window arrangement comprising a door with a door frame and a door leaf, or a window with a window frame and a window sash supporting a pane of glass, as well as an insulating device with an airtight surface structure. The insulating device can be attached / mounted to the door or window in such a way that, in the mounted state, an insulating space is formed between the insulating device and the door or window. It is particularly provided that the insulating device is preferably mounted to the window frame or door frame in a fixed position relative to the movable sash of the door or window. The insulating device is specifically designed and arranged such that the insulating space is formed between the airtight surface structure and a pane of glass held by the window sash, particularly when the window is closed.The insulating device is therefore specifically designed to be attached to the door frame or the window frame.

[0007] The problem can also be solved by a method for insulating a building opening, the method comprising at least the following steps: Attaching an airtight surface structure to a frame of an insulating device and mounting the insulating device on a window or door, so that an insulating space is formed between the airtight surface structure and the window or door.

[0008] In other words, the basic idea of ​​the invention is that the energy consumption of a building can be easily reduced by an end user attaching an insulating device to a window or door in such a way that an insulating air gap is formed between the airtight surface structure and the sash, at least when the window / door sash is closed, wherein the airtight surface structure is supported by the frame and can therefore be easily mounted on the door or window in a more or less tensioned state.

[0009] The airtight surface structure is preferably formed using a foil.

[0010] The airtight sheet / film is preferably transparent and absorbs as little light as possible that passes through it. In particular, the sheet / film is also designed so that transmitted light is not scattered. In one embodiment, the airtight sheet / film can also be colored / tinted so that the solar radiation entering through the building opening can be reduced. In principle, the airtight sheet / film could also be opaque.

[0011] The frame may be designed to have profile strips made of plastic or metal, particularly aluminum. For example, the frame may have four profile strips, with adjacent profile strips arranged at right angles around each other. Corner connectors may be used to join adjacent profile strips. The profile strips are, in particular, extruded profile strips made of plastic or metal (aluminum).

[0012] It may be provided that the insulating device is supplied to the end user as a pre-assembled unit, in which the frame, which may consist of several parts, is already assembled and the surface structure is attached to the frame. Alternatively, it may be provided that the insulating device is supplied to the end user as a kit, in which case the components or sub-assemblies of the insulating device are provided to the end user and the end user must assemble the components and / or sub-assemblies.

[0013] Particularly in the latter case, the frame may be adjustable in size, allowing the end user to adapt it to the size of the window / door. In the simplest case, the end user can shorten the profile strips supplied as individual parts and cut the resulting frame accordingly.

[0014] For particularly easy, tool-free adjustment of the frame size, the frame can be designed to include sliding / telescoping profile strips. Each side / strut of the frame thus consists of at least two, preferably exactly two or three, profile strips that can be telescoped / slide relative to each other to adjust the length of that side / strut. For example, one profile strip can be designed as an inner profile strip that is telescopingly inserted into an outer profile strip. In this context, it can also be provided that adjacent profile strips from different sides / struts of the frame can be connected / joined together at a corner using corner connectors.

[0015] Particularly when the insulating device is provided to the end user as a prefabricated finished product, the frame may be formed by a single bent metal element, especially a bent metal rod. Such a metal rod is bent into a rectangular frame according to the size of the window, and its ends may be joined together. It may be particularly possible for the frame to be bent and elastically prestressed before the surface element is attached to it, so that after attachment the surface element is uniformly prestressed by the frame. Such a frame formed from a metal rod can be designed to be particularly space-saving.

[0016] In a particularly preferred embodiment, the frame is dimensioned such that it can be arranged in a space formed between the building frame (window / door frame) and the closed (window / door) sash. The metal rod or profile strips (and optionally any fixing elements attached to the metal rod or profile strips for securing the surface structure) have a width of no more than 2 cm in (or parallel to) the plane defined by the spanned surface structure and a height of no more than 1 cm perpendicular to that plane. Such a relatively thin frame can be easily inserted into the building frame.

[0017] If, however, no corresponding space is formed in the window frame when the window sash is closed, or if the frame of the insulating device is larger, it may be provided that mounting elements are attached to the frame, allowing the insulating device to be attached to the building frame. In particular, at least two, preferably four, mounting elements are attached to the frame of the insulating device. The mounting elements are hook-shaped and overlap the building frame, so that the insulating device, with its frame or, if applicable, with a (brush) seal attached to the frame, rests against the outside of the building frame.

[0018] Particularly when the insulating device is provided to the end user as a kit consisting of several components or of several assemblies, each comprising at least two components, it may be designed that the surface structure is attached to the frame by means of a force-fit and / or form-fit connection, in particular by means of at least one fixing element. For this purpose, for example, the frame's profile strips may have an outer contour extending along their longitudinal extent, such as a projection or recess, with a fixing element, which may also be strip-shaped, having a fixing contour that is complementary to the frame contour. It is thus possible for the surface structure to be clamped between the frame and the fixing element. This makes it particularly easy for an end user to fix the surface structure to the frame.

[0019] Particularly when the insulating device is provided to the end user as a prefabricated end product, the sheet structure can be bonded to the frame. For example, the sheet structure can be glued to the frame or attached to the frame by welding, in which case the frame may have a plastic coating, so that the sheet structure is bonded to the coating of the frame by thermoplastic deformation during welding.

[0020] The invention and its technical context are explained below using the figures as examples. They show schematic representations. Figure 1: a window with an insulating device attached to it with the window sash open, Figure 2: a sectional view through the window with the window sash closed, Figure 3: a detail view of the window with the window sash closed, Figure 4: a frame strut of a frame of the insulating device with a fixing element, Figure 5: two frame struts with a surface structure attached to them and Figure 6: another strut with a further embodiment of a fixing element.

[0021] The in the Figures 1 to 3 The window arrangement shown comprises a window 1 and an insulating device with a frame 2 and a surface structure 3.

[0022] Window 1 has a window frame 1.1 and a pivotable window sash 1.2. A window pane 1.3 is formed in the window sash 1.2. The insulating device comprises a frame 2 and an airtight surface structure 3 held / stretched by the frame 2, which can, for example, be made of a transparent film. As, for example, in the Figure 4 As shown, the sides / frame struts of frame 2 are formed by profile strips 5. The profile strips 5 have a frame contour 2.1 into which a similarly strip-shaped fixing element 7 with a fixing contour 7.1 can be clipped. Accordingly, the frame contour 2.1 is adapted to the fixing contour 7.1 of the fixing element 7.1.

[0023] As especially from Figure 5As can be seen, the airtight surface structure 3 can be fixed between the profile strips 5 and the fixing element 7. It can be provided that adjacent profile strips 5 are connected to each other at the corner by means of corner connectors (not shown). Figure 5 It can be seen that the airtight surface structure protrudes outwards beyond the profile strips 5.

[0024] While that in the Figures 4 and 5 The depicted fixing element 7 is omega-shaped in its cross-sectional design, is in Figure 6 The fixing element 7 is designed as a keder cord, which is inserted into the frame contour 2.1 to fix the surface structure 3. From the Figure 2 and especially from the detailed view of the Figure 3 It can be seen that the insulating device with the frame 2 is arranged in a space 6 which is formed between the window frame 1.1 and the window sash 1.2 when the window sash 1.2 is closed.

[0025] The surface structure 3, held by the frame 2, is arranged parallel to the window pane 1.3 when the window sash 1.2 is closed, so that an air-filled insulating space 4 is formed between the airtight surface structure 3 and the window pane 1.3. This air-filled insulating space 4 thus provides an additional insulating layer that an end user can easily retrofit, especially in older windows, thereby reducing a building's energy consumption.
