FRAME AND WINDOW INSTALLATION ELEMENT WITH COMPRESSION INSERT

Description

[0001] The present invention relates to a frame and a window installation element.

[0002] Typically, window and door elements, which consist of a frame and usually a sash element that can be moved relative to the frame, are only installed in the brickwork window and door openings after the shell has been constructed. Therefore, once the shell has been constructed, the window installer must first measure the brickwork window and door openings. Then, the windows and doors are custom-made. Finally, the window installer must install the windows and doors in the brickwork window and door openings and secure them in such a way that no thermal bridges are created.

[0003] This method has a number of disadvantages.

[0004] The exact dimensions of the bricked window and door openings often do not match the dimensions planned by the architect. It is not uncommon for the window openings to differ by a few millimeters or even centimeters, even though the architect has designed several identical windows. Therefore, in custom manufacturing, each individual window must be created with different dimensions. Furthermore, it is necessary to clearly label the windows to ensure that the correct window is installed in each bricked window opening. The same applies to doors. Furthermore, the window manufacturer must visit the construction site several times. Furthermore, producing the windows or doors only after the bricked window and door openings have been measured leads to construction delays.

[0005] Finally, avoiding thermal bridges during window or door installation requires special attention, which can only be ensured by specially trained specialists. It is particularly important to note that the window, and especially the window frame, expands more than the surrounding masonry when temperatures rise.

[0006] Therefore, frames have already been proposed that are "bricked in" during the construction of the shell, thus determining the exact size of the window or door opening. Measurement is then no longer necessary. Furthermore, the corresponding window elements can be manufactured in advance, as the dimensions of the frame are already determined before the shell is constructed. The window elements can then be attached to the frame in a subsequent step once it is integrated into the masonry. Such a system is described in DE 8027442 U1.

[0007] However, the frame described has not been widely adopted because of the risk of shear forces being applied during walling, resulting in the crossbars and reveal parts no longer being exactly perpendicular to each other. Both the fastening of the frame in the brickwork opening and the installation of the window element into the frame require specially trained personnel. For example, the frame must be held in place until the surrounding masonry is constructed so that the frame can be screwed to the masonry.

[0008] DE 10 2018 121 776 A1 has therefore already proposed a frame with an upper and a lower crossbar and two reveal sections, in which the reveal sections each connect the lower and upper crossbars. A third crossbar is provided to stabilize the frame and absorb the transverse forces. However, this frame is quite complex.

[0009] DE 295 08 231 U1 describes a sound insulation element for prefabricated houses. CN 111 472 666 describes a multi-part frame with a sound-absorbing element sandwiched between its parts. DE 102 48 096 B3 shows a safety window designed to absorb vibrations caused by a blast.

[0010] Based on the described prior art, it is therefore the object of the present invention to provide a solution which at least partially avoids the disadvantages mentioned.

[0011] This object is achieved according to the invention by a frame and a window installation element according to claim 1 or 2.

[0012] Throughout the day or throughout the year, the temperatures to which the window frame is exposed vary considerably. Typically, the window frame has the highest coefficient of thermal expansion of all structural components. This leads to deformation of the window frame, particularly in summer when the sun shines directly onto the window. The window frame comprises at least an upper and a lower frame section, as well as two side frame sections. For example, since the upper and lower frame sections expand horizontally, this causes the side frame sections to deform outwards where they connect to the upper and lower frame sections.

[0013] The compression insert is designed to absorb the corresponding forces exerted, in particular, by the upper and lower frame sections on the side frame sections, or by the side frame sections on the upper and lower frame sections, and to allow for a certain degree of deformation of the frame section. The frame sections are attached to the respective frame sections for this purpose. Once the window is installed, the frame section is positioned between the window frame and the surrounding masonry, allowing thermal expansion of the window frame.

[0014] For this purpose, the frame part can have a recess in which the compression insert is arranged. The depth of the recess preferably corresponds approximately to the thickness of the compression insert, so that the compression insert sits flush in the recess.

[0015] Since, as already explained, the greatest horizontal forces acting on the side frame parts of the window only occur in the area in which the side frame parts are in contact with the upper or lower frame part, in one embodiment the frame part can also have at least two compression inserts that are arranged at a distance from one another, wherein the frame part is preferably fastened to a side frame part in such a way that one compression insert intersects an imaginary line along which the upper frame part extends, and the other compression insert intersects an imaginary line along which the lower frame part extends. In this way, a corresponding compression insert is provided exactly at the points where the greatest forces occur, in which the frame can expand.

[0016] In a preferred embodiment, the base body of the frame part consists of a thermally insulating element. Any material with a thermal conductivity level of WLS 050 or lower can be used as the thermally insulating material. Typical insulating materials such as EPS, XPS, mineral wool, stone wool, or organic or inorganic polymers are particularly suitable.

[0017] The present invention relates to a frame with two lateral reveal parts, a lower crossbar, and an upper crossbar. Such a frame can be placed on existing masonry and embedded, as described above. In a subsequent step, the window is then secured in the frame. With regard to the frame, the aforementioned object is achieved in that at least one of the lateral reveal parts or one of the two crossbars is designed as a frame part, as described above.

[0018] It is particularly preferred to design the two lateral reveal parts as frame parts as described above.

[0019] However, it is also possible to design both the side reveal parts as well as the upper and lower crossbars as frame parts with compression inserts.

[0020] The present invention further relates to a window installation element comprising a window or door element and two lateral reveal parts. The window or door element has a frame with two lateral frame parts, an upper frame part and a lower frame part, as well as a panel arranged within the frame, such as a window pane. The two lateral reveal parts are connected to the frame, and the window installation element has an upper, a lower, two lateral, and an inner and an outer surface.

[0021] According to the invention, the above-mentioned object is achieved with this window installation element in that at least one lateral reveal part is designed as a frame part with a compression insert, as described above. In a preferred embodiment, both lateral reveal parts are designed as frame parts with a compression insert.

[0022] Such a window installation element consists of the finished window, each of which already has a side reveal attached to it. This window installation element according to the invention can then be placed on the wall or floor as a whole on the construction site and then bricked in in the next step.

[0023] The third crossbar described in DE 10 2018 121 776 A1 can be omitted, as the forces are absorbed by the existing window. In addition, additional

[0024] Elements that enclose the window at the top or bottom are omitted, which reduces and simplifies the price and handling of the window installation element.

[0025] However, it is also possible to first brick the window reveals and then insert the window installation element into the window opening from above. The window installation element can also be inserted into an existing window opening from the outside or inside.

[0026] The frame can, for example, surround a window pane. However, other fillings, such as opaque fillings, are also conceivable.

[0027] In a preferred embodiment, the lower frame part forms at least a portion of the lower surface.

[0028] The window installation element is thus placed on the wall or floor with the lower frame part of the window frame.

[0029] In a further preferred embodiment, the compression insert is in contact with one of the lateral frame parts such that the compression insert is arranged between the lateral reveal part and the lateral frame part. In this case, both lateral reveal parts are preferably designed as frame parts with a compression insert, so that the compression insert of each lateral reveal part is in contact with one of the lateral frame parts.

[0030] Since, as already explained, the greatest horizontal forces acting on the lateral frame parts only occur in the area where the lateral frame parts are in contact with the upper or lower frame part, in one embodiment, each lateral reveal part can also have at least two compression inserts arranged at a distance from one another, wherein preferably one compression insert intersects an imaginary line along which the upper frame part extends, and the other compression insert intersects an imaginary line along which the lower frame part extends. This provides a corresponding compression insert in which the frame can expand, precisely at the points where the greatest forces occur.

[0031] In a preferred embodiment, the lateral reveal parts each also form a section of the lower surface of the window installation element, with the section of the lower surface formed by the lower frame part and the two sections of the lower surface formed by the lateral reveal parts preferably being arranged in a common plane. In other words, both the lateral reveal parts and the lower frame part rest on the masonry when the window installation element is placed on the wall. The window installation element can then simply be embedded in the wall. The presence of the window builder on the construction site is not required at all.

[0032] The side reveal sections hold the window in its correct horizontal position and prevent the formation of thermal bridges at the side reveal sections. It may also be necessary to insulate the window installation element, at least at its lower frame section and, if necessary, also at its upper frame section. This, however, does not require the presence of the window installer.

[0033] In a further preferred embodiment, the two lateral reveal parts are connected to the frame by means of screws or nails that extend through the lateral reveal parts into the frame. This enables simpler installation, which is also essentially invisible. In the prior art, the window is subsequently installed in the wall opening or in the frame, so that the corresponding fastening elements, such as screws or nails, have to penetrate into the masonry from the inside of the frame. By providing the window installation element according to the invention, the lateral reveal parts can be conveniently connected to the window frame by hammering or screwing the corresponding fastening elements into the frame from the outside through the lateral reveal parts. Once the window installation element has been bricked in, the fastening elements are no longer visible.

[0034] In a further preferred embodiment, the lateral reveal parts each have a stop rib projecting in the direction of the window frame, against which the lateral frame parts rest.

[0035] This stop rib facilitates the installation of the side reveal parts, as they are now positioned against the side frame parts in such a way that the side frame parts also rest against the stop rib, limiting the movement of the window frame toward the inside or outside surface, depending on the position of the stop rib. In this position, the side reveal part can be attached to the window frame.

[0036] In a further preferred embodiment, at least one lifting element is provided, which is or can be attached to a lateral reveal part. Preferably, two lifting elements are provided, each of which is or can be attached to a lateral reveal part. These lifting elements can, for example, be appropriately screwed-on eyelets, with the aid of which the entire window component can be suspended from a crane, allowing the window installation element to be easily positioned in the correct location.

[0037] In a further preferred embodiment, a reinforcement profile is incorporated into the side reveal sections, preferably extending over the entire length of the side reveal section. The reinforcement profile provides additional stability and is preferably made of a metal, particularly preferably steel. In any case, the reinforcement profile should have a higher flexural strength than the side reveal sections into which the reinforcement profile is incorporated.

[0038] In a preferred embodiment, the reinforcement profile is arranged on the side of the lateral reveal part facing away from the frame. Furthermore, if a lifting element is present, the lifting element is attached or can be attached to the reinforcement profile.

[0039] In a further preferred embodiment, it is provided that the upper frame part forms at least a portion of the upper surface and the lateral reveal parts each form a portion of the upper surface, wherein preferably the portion of the upper surface formed by the upper frame part and the two portions of the upper surface formed by the lateral reveal parts are arranged in a common plane.

[0040] Alternatively, in a likewise preferred embodiment, a box for a darkening and / or shading system is provided above the upper frame part, which box forms at least a portion of the upper surface and the lateral reveal parts each form a portion of the upper surface, wherein preferably the portion of the upper surface formed by the box and the two portions of the upper surface formed by the lateral reveal parts are arranged in a common plane.

[0041] Further advantages, features, and possible applications will become clear from the following description of preferred embodiments and the accompanying figures. They show: Figure 1 is a perspective view of a first embodiment of the window installation element according to the invention, Figure 2 is a perspective view of a lateral reveal part of the embodiment of Figure 1, Figure 3 a perspective view of the embodiment of Figure 1 with mounted concrete anchor and without guide rail, Figure 4 a perspective view of a second embodiment of the window component according to the invention, Figure 5 an exploded view of the embodiment of Figure 4 , Figure 6 is an exploded view of a third embodiment of the window installation element according to the invention and Figure 7 is an exploded view of a fourth embodiment of the window installation element according to the invention.

[0042] In Figure 1 A first embodiment of the window installation element according to the invention is shown in a perspective view. This window installation element has a window element 1 and two lateral reveal parts 2. The window element 1 has two lateral frame parts 3, of which Figure 1only one is visible, as the other is concealed by the side reveal part 2. The frame also has an upper frame part 4 and a lower frame part 5. The upper frame part 4, the lower frame part 5, and the two side frame parts 3 enclose a filling 6, which can be a pane of glass, for example. In principle, however, other materials are also possible.

[0043] The two lateral reveal parts 2 are connected to the frame. A compression insert 16 is provided between the two lateral frame parts and the two lateral reveal parts. This compression insert is capable of absorbing deformations of the frame, e.g., due to temperature-related expansion of the frame parts, without deforming the outer sides of the lateral reveal parts 2, which rest against the masonry when installed.

[0044] The Figure 1The window installation element shown has an upper surface, a lower surface, two side surfaces, and an inner and an outer surface. The side reveal parts 2 completely cover the side frame parts 3 on their outward-facing side. In the embodiment shown, the lower frame part thus forms at least a section of the lower surface. In other words, no further element is provided below the frame. The window installation element can be delivered to the construction site as such and simply placed on a wall or a poured floor. In the next step, the window installation element is then bricked or cast in. The presence of the window manufacturer on the construction site is therefore generally not required. This significantly reduces costs.

[0045] In the Figure 1In the embodiment shown, the lateral reveal parts also each form a section of the lower surface, with the sections of the lower surface formed by the lateral reveal parts 2 and the section of the lower surface formed by the lower frame part 5 being arranged in a common plane. The entire window installation element is therefore flat on its underside and can be placed directly onto the masonry without the use of corresponding leveling blocks. However, it is also possible to additionally work with leveling blocks, especially if the masonry is not sufficiently horizontal.

[0046] In this embodiment, the upper surface of the window installation element is designed in the same way. Here, too, the surface is formed by both the upper frame part 4 and the side reveal parts 2, with the upper surface also being flat.

[0047] The side reveal parts 2 can be connected to the side frame parts 3 by the window manufacturer. For example, they can be screwed, nailed, or glued to the frame parts. The fastening can be made from the outside, i.e., through the outer surfaces of the side reveal parts 2. The fastening is then no longer visible once installed. The side reveal parts are made entirely or almost entirely of a heat-insulating material, such as polystyrene.

[0048] The side reveal parts 2 can be manufactured in a width corresponding to the masonry width. In this case, the window installation element is flush with the masonry with both its inner and outer surfaces. Furthermore, the window installation element can be easily packaged and safely transported, since the larger width of the side reveal parts 2 relative to the window element 1 protects both the frame and the filling 6 from accidental damage.

[0049] In Figure 2A perspective view of a side reveal part 2 is shown. The side reveal part 2 has a stop rib 7 projecting toward the window frame. This stop rib 7 assists in positioning the side reveal parts 2 relative to the side frame part 3 before they are connected to each other and, secondly, ensures that the window has greater stability within the window opening once the window installation element is bricked in.

[0050] For the assembly of the lateral reveal parts 2, these are placed on the lateral frame parts 3 in such a way that the lateral frame part rests on the stop rib 7 both on its edge facing the lateral reveal part 2 and on the edge facing the outside of the window installation element.

[0051] On the side of the lateral reveal part 2 facing away from the frame, a lifting element 8 is provided, which in the example shown consists of a metal eyelet and a corresponding fastening plate with which the lifting element can be screwed to the lateral reveal part.

[0052] Such a lifting element 8 is provided on both lateral reveal parts 2, so that the window installation element as a whole, ie in the Figure 1 shown configuration, can be lifted using a crane and transported to the appropriate location.

[0053] In order to increase the stability of the lateral reveal parts 2, the lateral reveal part 2 has two undercut grooves 10 on its side facing away from the frame, into which a reinforcing profile 9, which in the example shown is made of metal, is inserted.

[0054] The lifting element is then connected to the reinforcement profile 9. The reinforcement profile 9 also has corresponding undercut grooves 10, which are used for the installation of additional components, such as wall anchors that protrude laterally and are integrated into the masonry.

[0055] The side reveal part 2 also has a groove on the side facing the frame, in which a guide rail 11 is accommodated. The guide rail serves to accommodate a shading system, such as a roller shutter or a Venetian blind system.

[0056] In Figure 3 An alternative embodiment of the invention is shown. This differs from the Figures 1 and 2The embodiments shown are essentially distinguished by the fact that the guide rail 11 has been omitted and, instead of the lifting element 8, ceiling anchors 12 are provided on the lateral reveal parts 2. These ceiling anchors 12 are intended to engage into the lintel sheathing to be arranged above the window or the ceiling sheathing above it, so that after the cast lintel or the cast ceiling has hardened, the ceiling anchors remain in the concrete and provide the window installation element with additional stability.

[0057] In the Figures 3 to 5 Perspective views and an exploded view of a third embodiment of the invention are shown. The same reference numerals have been used for identical components. Therefore, only the differences between the third embodiment and the two previously described embodiments will be discussed below.

[0058] Window element 1 has remained unchanged from the previous embodiments. However, the window installation element here also features a box for a blackout and / or shading system, designed as a roller shutter box 13. This roller shutter box 13 is arranged above the upper frame part 4. This box can also be screwed to the side reveal parts 14. In this embodiment, the side reveal parts 14 protrude upwards above the upper frame part, thus forming a receiving space for the roller shutter box 13.

[0059] As particularly in Figure 4As can be seen, the upper surface of the window installation element is now formed on the one hand by the roller shutter box 13 and on the other hand by the upper edge surfaces of the lateral reveal parts 14. Here, too, the upper surface is flat, ie the sections of the lateral reveal parts 14, which form the upper surface of the window installation element, and the sections of the roller shutter box 13, which form the upper surface of the window installation element, lie in a common plane.

[0060] The side reveal parts 2 also have a stop rib 7, which, however, no longer extends over the entire length of the side reveal part 14, but only has a length corresponding to the height of the window element 1. Thus, the stop rib 7 forms a support surface 15 on which the roller shutter box 13 can be placed.

[0061] In Figure 6another embodiment of the invention is shown in an exploded view.

[0062] This differs essentially in that neither lifting elements nor ceiling anchors are provided. However, it is clearly visible in this figure that the lateral reveal parts 17 each have a compression insert 16. The compression inserts 16 are more elastic than the material from which the lateral reveal parts 17 are made. This means that any thermal expansion of the window element 1 that may occur is also possible when the window installation element is installed. Figure 6 In the embodiment shown, the compression insert extends over the entire length of the lateral reveal part 17, so that the lateral frame parts rest completely on the compression insert.

[0063] In this embodiment, however, care must be taken that when attaching the lateral reveal parts 17 to the frame, the connecting screws are not tightened too much, so that the compression insert 16 is not already heavily compressed during the installation of the window installation element, so that it is no longer available for further compression.

[0064] In Figure 7A further embodiment of the invention is shown. The lateral reveal part 18 now has several compression inserts 16, which are separated from one another by corresponding stop surfaces 19. The compression inserts 16 are arranged where the greatest expansion of the window element is expected. In the illustrated embodiment, the frame not only has the already described upper and lower frame parts 4, 5 and the lateral frame parts 3, but also a transom 20, which in the illustrated embodiment is arranged approximately midway between the upper frame part 4 and the lower frame part 5.

[0065] When the window element heats up, e.g., due to intense sunlight, horizontal expansion occurs primarily in the areas where the upper frame part 4, the lower frame part 5, and the transom 20 are connected to the side frame parts 3. The compression inserts 16 are arranged in these areas, allowing the side frame parts 3 to bend. This design also has the advantage that there is no risk of the compression insert 16 becoming too compressed during assembly, since the side frame parts 3 rest on the stop surfaces 19. The screw connection is then best made in the area of ​​the stop surfaces 19 and not in the area of ​​the compression inserts 16. List of reference symbols
