Abstract

In a base seal with a floor surface, a reveal surface, and a wall surface, which comprise an inner side, and with a horizontal seal on the wall surface and an upright seal near the reveal surface, it is proposed that the two seals create a first sealing zone, and that a substantially planar outer seal is arranged on the outside of the floor surface and / or the reveal surface, creating a second sealing zone. Furthermore, a window arrangement with the proposed base seal is proposed.

Description

[0001] The invention relates to a base seal for windows according to the features in the preamble of claim 1.

[0002] DE 20 2022 105 704 U1 discloses a base seal, particularly for floor-to-ceiling windows, which is designed like a room corner, i.e. it has three surface elements aligned at right angles to one another as sections of a one-piece, seamless component. A first surface section is referred to as the floor surface and is intended to be placed on a base plate of a building during installation, e.g., on a basement or floor ceiling. A second surface section is referred to as the reveal surface because it is intended to be applied to the window reveal. A third surface section is referred to as the wall surface because it is intended to be aligned in the plane of the building's outer wall so that, for example, a window base installed later in connection with the window installation can be applied to this wall surface of the base seal.

[0003] As is known, sealing against moisture penetrating from the outside can be achieved by applying pasty sealants or elastic profile seals to the inner surface sections facing the window, thus achieving a seal against the window frame and / or the window base. The teaching of DE 20 2022 105 704 U1 relates to a horizontal, particularly horizontal seal on the wall surface of the base seal, which rests against the lower, horizontal section of the window frame or, below it, the window base, i.e., a front surface of the window frame or window base facing outwards from the building.Furthermore, an upright, in particular vertically running seal is described therein, which runs along the reveal surface and rests against the lower, horizontal section of the window frame or, below the window, the window base on their respective side surface, which runs at 90° to the front surface.

[0004] Close in the context of the invention means that the seal rests against the reveal surface, borders the reveal surface or runs at a short distance from the reveal surface, in particular with a parallel distance of a maximum of 15 to 50 mm, preferably 10 to 15 mm, particularly preferably less than 10 mm or less than 5 mm.

[0005] In the context of the present invention, the term "window" refers to an assembly comprising a (glass) pane, a window frame, and a window base. The window frame encompasses the pane and rests on the window base. Any frame of an openable window is also encompassed by the term "window frame" in this case. Any support profile is also encompassed by the term "window base" in this case. The window frame and window base can merge seamlessly, i.e., not immediately recognizably. Typically, a lower, horizontal section of the window frame forms the window base.

[0006] Furthermore, if terms such as inward or outward are used in the context of the present invention, reference is made to the orientation of the base seal in an installation situation in which the inward direction faces the interior of the building and the outward direction essentially faces the external building environment or faces other components of the building.

[0007] In practice, dimensional deviations can repeatedly occur when constructing the building wall and particularly when creating the window opening, also known as the window niche, so that the actual width of the window opening often deviates from the theoretical width specified in the building plan. If the base seal is intended to adjoin the window reveal, the actual distance between two opposite base seals at the two lower corners of the window opening may deviate from the theoretical distance specified in the building plan. Since the window is not manufactured according to the actual dimensions of the window opening, but rather according to plan, gaps may arise laterally from the window to the reveal, the size of which cannot be predetermined, and the respective gap width can vary from window to window.

[0008] The present invention is based on the object of proposing an improved window connection within a window recess of a building, thus ensuring particularly secure sealing. Furthermore, the invention is based on the object of offering an economically advantageous solution.

[0009] This object is achieved by a base seal according to the features of claim 1. Features of the invention are discussed below, with advantageous embodiments of the invention being described, inter alia, in the subclaims. These design features can be implemented in conjunction with the invention or can be independently inventive, independent of the invention, and they can be implemented either individually and independently of one another or in any combination, including the implementation of all of the aforementioned features, unless a combination is expressly or technically mandatory.

[0010] A base seal is proposed with a floor surface, a reveal surface and a wall surface, which comprise an inner side, and with a horizontal seal on the wall surface and with an upright seal close to the reveal surface, in particular with a maximum distance of 15 to 50 mm, preferably 10 to 15 mm, particularly preferably less than 10 mm or less than 5 mm, wherein the two seals create a first sealing zone, and wherein a substantially planar outer seal is arranged on the outer side of the floor surface and / or the reveal surface, which creates a second sealing zone.

[0011] In other words, according to a first aspect, the presented invention relates to a base seal, wherein the seal comprises several sealing zones. A first sealing zone is created by the two seals, namely the horizontal seal and the vertical seal. The first sealing zone serves to seal a window against the base seal. Regardless of the design of the seals, a second sealing zone with an external seal is essential to the invention. The second sealing zone serves to seal the base seal against the building, so that, for example, the rising of moisture past the base seal can be prevented.Surprisingly, it has been shown that the moisture ingress paths, which are known to be problematic in practice, are very effectively sealed by the interaction of the first and second sealing zones, as proposed.

[0012] Insofar as the two seals are described in the context of the present invention, on the one hand a seal comprising two separate sealing sections is included, and on the other hand also a single, common seal with two sections.

[0013] According to the invention, the outer seal is arranged on the outer surface of the floor surface or the reveal surface, i.e. on the side of the floor surface which faces the base surface or on the side of the reveal surface which faces the masonry of the building. It is particularly preferred that both the floor surface and the reveal surface have an outer seal. The outer seal is essentially flat, so that more than 50% of the outer surface of the floor surface or the reveal surface lies against an outer seal, preferably more than 80%. A fully adjacent outer seal is particularly preferred, so that 90 to 100% of the outer surface lies against an outer seal.

[0014] In one embodiment, it can be provided that the outer seal has a sealing compound.

[0015] In a preferred embodiment, the outer seal may comprise a sealing compound, in particular a pasty sealing compound, such as a bitumen-containing coating or the like. Particularly preferred are largely bitumen-free compounds, such as mineral sealing slurries, flexible, polymer-modified (thick) coatings, or the like. The sealing compounds can be easily applied to the surfaces using a squeegee, brush, roller, or the like.

[0016] In one embodiment, it can be provided that the outer seal comprises a rubber-elastic material.

[0017] Furthermore, it can be provided that the outer seal is applied to the outer surface in the form of a flat seal, for example in the form of one or more sealing films, sealing tapes, or the like. These surface seals can advantageously comprise a rubber-elastic material. The surface seals can advantageously be designed to be self-adhesive on at least one side to simplify installation. Independent of the design of the outer seal, a positive connection of the base seal to the masonry or to the base plate, for example a screw connection, can increase the contact pressure of the outer seal in addition to the dead weight of a window and thus a corresponding sealing effect.

[0018] For a window arrangement, which will be explained further below, it may be necessary to apply the external seal to any surfaces before installing the base seal. Alternatively or additionally, an external seal can be applied to the masonry or base plate.

[0019] In one embodiment, it can be provided that an inner seal is arranged on the inside of the floor surface, the reveal surface and / or the wall surface, which creates a third sealing zone.

[0020] In practice, the connection of a window in the floor area is known to be a highly problematic connection in terms of sealing. A third sealing zone can be provided in a further development, particularly for window connections that are particularly exposed in a usage configuration or installation situation.

[0021] In one embodiment, it can be provided that the two seals of the first sealing zone are designed in such a way that they seal in the same plane, this plane running parallel to the wall surface of the base seal.

[0022] Regardless of the design of the two seals of the first sealing zone, a second sealing zone can be provided in the event that moisture can pass through the first sealing zone, which is initially exposed to moisture, in the form of the aforementioned horizontal or upright seal. This third sealing zone can be arranged on the inside, i.e. on the sides of the floor surface, the reveal surface, and / or the wall surface facing the window frame or the window base in a usage configuration. Preferably, the inner seal is arranged on the inside of the floor surface and the reveal surface, in conjunction with seals of the first sealing zone, which are designed such that they seal in the same plane, this plane running parallel to the wall surface of the base seal, which will be explained in more detail below.

[0023] The third sealing zone can advantageously comprise a pasty sealing compound, as previously described for the second sealing zone, which is particularly effective as an adhesive and sealing compound. This pasty sealing compound can preferably be applied to the inner sides, e.g. in the form of a (uninterrupted) continuous bead, so that the base seal is bonded to the window frame and / or the window base or is additionally sealed. The uninterrupted bead ensures the desired sealing effect, and the bonding of the base seal to the window frame or the window base fixes the bonded components in their alignment to one another, thus also improving the effectiveness of the first sealing zone and maintaining it over a long period. Alternatively or additionally, the seal of the second sealing zone can comprise a sealing profile or flat gasket.

[0024] As previously indicated, in a further development, the sealing of the first sealing zone, namely both the wall and reveal surface of the base seal, can be carried out on the front surface of the window frame and / or the window base. The assumption here is that the front surface of both the window frame and the front surface of the window base located underneath run flush in a common plane, so that the two horizontal and vertical seals can easily lie against these two front surfaces, especially when the vertical seal extends from the window base upwards to the window frame. The horizontal seal and the vertical seal are particularly advantageous as sections of a single, common seal.

[0025] This design of the base seal is particularly advantageous as the first sealing zone in conjunction with the second sealing zone. The front surface of the window frame and the window base generally run in a defined plane, while the side surfaces of the window frame and the window base, which run at right angles to them, can be positioned at different distances from the window reveal, so that the first sealing zone already provides particularly effective sealing. In conjunction with the second sealing zone, which prevents moisture from penetrating the space between the masonry, particularly the backing wall, and the base seal, a particularly effective moisture barrier is proposed, which can solve a long-standing problem in practice.

[0026] By appropriately designing a seal that is intended to rest laterally against the window frame or window base, certain tolerances regarding the respective gap width can be bridged. However, the design of such a seal is technically complicated and / or economically disadvantageous, and in the case of particularly large dimensional deviations, the sealing function of the seal in question may also be limited, so that the desired sealing effect cannot be reliably guaranteed. Such problems are avoided by the inventive seal on the front surface, because the gap width that arises laterally between the window or window base and the reveal of the window opening does not affect the seal.

[0027] It may be advisable to use sealing profiles, for example in the form of extruded profiles, for a seal in the first sealing zone. In one embodiment, it can be provided that the upright seal is arranged on the front edge of the reveal and / or the wall surface of the base seal. If the seal is designed as an elastomer seal with a specific sealing profile cross-section, this cross-section can particularly advantageously have, on the one hand, a groove with which the seal can be pushed onto the front edge of the reveal surface, and, on the other hand, a sealing lip that extends up to the front surface of the window frame and lies sealingly against this front surface.

[0028] In another embodiment, however, the wall surface of the base seal is L-shaped, with a narrow, upright area that adjoins the reveal surface of the base seal, for example the front edge of the reveal surface.

[0029] For a further development, it can be provided that the two seals of the first sealing zone are each designed as a flat seal, which partly rests on a surface of the base seal and partly projects freely beyond the base seal.

[0030] In one embodiment, it can be provided that the two seals of the first sealing zone are designed together as sections of a single flat seal.

[0031] A particularly inventive further development relates to the design of the seal of the first sealing zone in the form of a flat seal, particularly preferably in the form of a flat seal comprising the two seals together as sections of a single seal.

[0032] Surprisingly, it has been shown that a flat gasket, i.e., a two-dimensional blank made of a suitable flat sealing material, is suitable for simplifying the tight connection of the base seal to the front surface of the window frame and / or the window base. Such a flat gasket is available as a commercially available semi-finished product and is therefore considerably more economical than a profile gasket, especially if a suitable sealing profile is not already available as a commercial product but would have to be manufactured as a profile extrudate with the desired profile geometry using a specially designed tool.

[0033] The further development of a flat seal is based on the idea that, on the one hand, the wall surface of the base seal runs essentially parallel to the plane in which the front surface of the window frame and / or the window base lies, so that a two-dimensional flat seal can be easily attached in such a way that it rests partly on the wall surface of the base seal and partly on the respective front surface, thus bridging the dividing point between the wall surface and the respective front surface. With this installation of the flat seal, it retains its two-dimensional, flat shape. The tight contact of the flat seal with these surfaces can be easily achieved by gluing the flat seal to the aforementioned surfaces.

[0034] The further development is based on the consideration that, on the other hand, the reveal surface of the base seal runs at right angles to the plane in which the front surface of the window frame and / or the window base lies. The flat seal, provided as a two-dimensional, flat surface element, can therefore also be easily installed so that it rests partly on the reveal surface of the base seal and partly on the respective front surface by bending it from its two-dimensional, flat shape into a 90° angle element, which is easily achieved. In this case, too, the tight contact of the flat seal with the aforementioned reveal and front surfaces can be easily achieved by gluing the flat seal to the aforementioned surfaces.

[0035] For example, an economically available flat sealing material supplied as a roll can be used, which is glued to the wall surface of the base seal and to the respective front surface of the window frame and / or the window base.

[0036] In one embodiment, the adhesive is applied in the form of individual adhesive beads to the flat gasket and / or the respective front surface before the flat gasket is pressed against the front surface. For example, the adhesive is applied in the form of two or more parallel adhesive beads to create multiple moisture barriers and thus ensure a reliable sealing effect.

[0037] In one embodiment, the adhesive is applied evenly and essentially over the entire surface of the flat seal, e.g., as a spray adhesive. Because the adhesive is not first applied to the front surface of the window frame and / or the window base, unwanted excess adhesive is avoided. Furthermore, the fact that the adhesive is essentially applied over the entire surface of the flat seal supports a reliable sealing effect, since even in smaller areas where the bond might not be effective, an effective bond all around this area achieves the desired seal.

[0038] Two sealing sections running at an angle to each other on the aforementioned front surfaces of the window frame and window base can be created using two separate, correspondingly angled flat gaskets. This maximizes the utilization of semi-finished flat gasket materials, e.g., in the form of a sealing sheet delivered on a roll or a flat, two-dimensional sealing sheet, and reduces waste caused by waste. Alternatively, a suitably designed blank, such as an L-shaped piece, can be cut from the semi-finished flat gasket to create a seamless seal and ensure the desired sealing effect with exceptional reliability.

[0039] In addition to ensuring that the adhesive is applied evenly and across the entire surface of the flat seal, a self-adhesive design of the flat seal makes handling of the base seal particularly easy on site. Therefore, all that needs to be done on site is to remove a protective film from the section of the flat seal that protrudes beyond one or more surfaces of the base seal. This protruding section of the flat seal can then simply be pressed onto the respective front surface of the window frame and / or window base, effectively bonding it to the seal.

[0040] In one embodiment, it can be provided that the seals protrude at least 20 mm beyond the base seal. In order to ensure reliable sealing, the flat seal can advantageously have a free projection of at least 20 mm or 25 mm, in particular of 30 to 80 mm, with which it protrudes beyond those surfaces of the base seal against which it rests, in order to enable a correspondingly large-area bonding with the respective front surface with this projection.

[0041] In particular, if no profile rail is mounted on the window frame that serves as a roller shutter guide, the flat seal according to the invention can be used without any problems, since it is then ensured that a sufficiently large area is available on the window frame to apply the flat seal to it and to bond it tightly to the window frame.

[0042] In particular, the seals of the first and third sealing zones can be made of elastomeric materials known from practice. The seals can particularly preferably comprise rubbers, particularly preferably an ethylene propylene diene (monomer) rubber (EPDM).

[0043] The three surface elements of the base seal are generally intended to be aligned at right angles to one another. In a further development, the wall surface can be oriented diagonally inward, so that at the edge of the wall surface, an opening angle between the wall surface and the reveal surface is less than 90°, in particular between 80 and 90°, particularly preferably between 85 and 90°. In this way, a prestress can be achieved that supports the sealing effect, with which the seals, or sections of a seal, are pressed against the front surface when the window frame or window base is inserted into the base seal and pressed against the wall surface.

[0044] According to a second aspect, the invention presented relates to a window arrangement with a window frame and a window base arranged thereunder forming a window, and with a base seal, with a number of the features described above, wherein the window is arranged in a window niche of a building and the outer seal rests against a backing wall forming the window niche and / or a base plate of the building.

[0045] A number within the meaning of the invention can refer to one or more of a respective feature.

[0046] The proposed window arrangement comprises, first, a window frame and a window base arranged underneath, creating a window. Second, it has a base seal, wherein the base seal may have one or more of the features described above. Third, the window is arranged in a window recess of a building created by a backing wall. It is essential for the window arrangement that the outer seal substantially rests against a backing wall and / or a base plate of the building.

[0047] For a particularly preferred further development of the window arrangement, it can be provided that the two seals of the first sealing zone rest against a front surface of the window frame and / or the window base.

[0048] In one embodiment, it can be provided that a roller shutter guide is arranged on the window frame, wherein the roller shutter guide is arranged offset on the window frame towards the window pane in such a way that the portion of the front surface of the window frame which is located on one side of the roller shutter guide is wider than the portion which is located on the other side of the roller shutter guide.

[0049] Furthermore, for a further development, it can be provided that a roller shutter guide is arranged on the window frame, and that the roller shutter guide has a recess at the level of the base seal, which is adjacent to the front surface of the window frame, and that the upright seal of the base seal extends into the recess of the roller shutter guide.

[0050] If the window is to be fitted with roller shutters, so-called roller shutter guides are arranged opposite one another on the front surface of the window frame. These are vertical guide rails in which the respective edge of the roller shutter runs in a groove of the respective roller shutter guide. In one embodiment of the window arrangement according to the invention, the roller shutter guides are arranged closer to the window pane on the window frame, so that a correspondingly narrower roller shutter is used. This creates sufficient space on the side of the window frame outside the two roller shutter guides to ensure that the vertical seal of the base seal can effectively adhere to the window frame.

[0051] In the event that the window opening is narrower than planned due to dimensional deviations and the gap between the window frame and the window reveal is correspondingly small, the arrangement of an upright seal in the first sealing zone, particularly on the front of the window frame, can potentially be problematic if the available space laterally outside the two roller shutter guides is insufficient, even if the roller shutter guides are offset from the window pane. To prevent the sealing profile, flat seal, or the like from being unduly deformed due to the limited space in the case of an elastomer seal, which could impair the effectiveness of the seal, a recess can be provided in the roller shutter guide in a particularly inventive manner.This recess can be limited to the lower area of ​​the roller shutter guide, namely to the area at which the upright seal of the first sealing zone of the base seal is provided. The recess is provided in the profile cross-section of the roller shutter guide where the roller shutter guide rests against the window frame, namely on the outside of the roller shutter guide facing outwards, i.e. towards the window reveal and away from the groove of the roller shutter guide. This recess creates a gap into which the upright seal of the base seal can be inserted, allowing it to rest against the window frame as intended and thus provide effective sealing.

[0052] In one embodiment, it can be provided that the two seals of the first sealing zone are glued on the one hand to the base seal and on the other hand to the respective front surface, and that the outer seal is glued on the one hand to the floor surface and / or reveal surface and on the other hand to the base plate and / or to the backing wall.

[0053] Thus, the seal of the first sealing zone can be bonded to the base seal on the one hand and to the respective front surface on the other. Furthermore, the outer seal can be bonded to the floor surface and / or reveal surface on the one hand and to the base plate and / or the masonry on the other. Particularly preferred for the design of the bonded seals is a paste-like sealing compound, as described above. This ensures reliable sealing.

[0054] In one embodiment, the base seal is screwed to the window frame, the window base, the backing wall and / or the base plate. Regardless of whether the components are glued together, the screw connection can also ensure that the components maintain their desired alignment to one another, for example to ensure and maintain the effectiveness of an elastomer sealing profile, a flat gasket or a sealing compound. Furthermore, the screw connection can be provided alternatively or in addition to the use of a pasty sealing compound or a pasty adhesive and sealing compound and serve to fix the components that are to be sealed against one another and / or glued together in their desired alignment to one another, for example until the adhesive used has achieved the required bond strength.

[0055] The use of the presented base seal is particularly advantageous for the purpose of an assembly method for producing a window arrangement, wherein the window arrangement comprises a window frame, a window base arranged thereunder and a base seal, wherein the window arrangement or the base seal can have one or more of the features described above and is intended to be used in a window niche for producing a usage arrangement.

[0056] According to the proposal, the base seal is attached to a base plate of a building and / or to a wall of the building, for example by screwing and / or gluing, with an external seal previously applied to the outside of the floor surface and / or the reveal surface and / or the backing wall and / or the base plate. Furthermore, a window is inserted into the base seal such that the window base rests on the base surface of the base element. Furthermore, for installation, the seals or sections of a common seal of the first sealing zone are preferably applied to the front surface of the window frame or window base.

[0057] In one embodiment, a pressing tool is expediently used when applying the two seals of the first sealing zones. In a particularly inventive embodiment, a tool provided for this purpose has a handle section and a pressure section, wherein the handle and pressure sections are aligned at an angle to one another. The pressure section is advantageously designed as a flat squeegee. The pressure section serves to be able to press the seal and is furthermore suitable, for example, for penetrating into the gaps in multi-layer masonry or into the gaps between the masonry and the window, in order to thus be able to apply the seals of the front surface in a sealingly effective manner even if the seal is directly concealed by the masonry and / or by a roller shutter guide.

[0058] It is recommended that the base seal be mounted on a solid foundation. Therefore, one design of the installation procedure may involve first extending the base plate outward into the building's window recess. The base seal can then be supported in sections on the original base plate and in sections on the base plate extension. Furthermore, it can be attached to the base plate (extension) and / or to the building wall using screws and / or adhesives.

[0059] While the invention has been described herein for a solid construction building, the proposal is not limited thereto. Rather, the invention can equally be applied to other construction methods, for example, buildings constructed from timber, hybrid construction, or others.

[0060] Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of exemplary embodiments based on the purely schematic drawings, whereby individual features or a combination of features of the illustrated exemplary embodiments can also be implemented independently of the remaining design in a proposed base seal or window arrangement. Fig. 1 a perspective view of a first embodiment of a base seal, Fig. 2 a perspective view of a window arrangement with the base seal from Fig. 1 , Fig. 3a, a perspective view of a second embodiment of a base seal, namely on the inside ( Fig. 3a ) and on the outside ( Fig. 3b ), Fig. 4 a perspective view of the base seal from Fig. 3 in an installation situation, Fig. 5 a perspective view of the installation situation Fig. 4 , Fig. 6 a perspective view of a window arrangement with the base seal from Fig. 3 , and Fig. 7a, b further perspective views of the window arrangement from Fig. 6 .

[0061] Fig. 1 shows a perspective view of a first embodiment of a base seal 1, which is designed in the manner of a room corner with three surface elements aligned at right angles to each other as sections of a one-piece, seamless component. The first surface section is referred to as the floor surface 3. The second surface section is referred to as the reveal surface 4. The third surface section is referred to as the wall surface 5 (see also Fig. 2 ).

[0062] In the illustrated embodiment, the wall surface 5 is approximately L-shaped, with a lower section 5a located below a window tread 103 of a floor-to-ceiling window, and an upper section 5b, which adjoins the reveal surface 4 as a narrow strip and runs upright. A sealing profile 20 is attached to each of the two edges of the wall surface 5, which run at an angle to one another. The sealing profile 20 has a groove 21 in its cross-section which accommodates the respective edge of the wall surface 5. The sealing profiles 20 are glued to the wall surface 5 using adhesive that has been previously introduced into the groove 21. Both sealing profiles 20 lie in the same plane and are intended to rest against a front surface 104 of a window frame 101 and the front surface 104 of a window base 102 located below.The two sealing profiles 20 are glued together where they abut, so that overall an uninterrupted and seamless, L-shaped seal 2 is created.

[0063] The sealing profile 20 is attached with its groove 21 to the narrow, upright sections of the wall surface 5. Since both sealing profiles 20 abut the front surfaces 104 of the window frame 101 and the window base 102, respectively, both sealing profiles 20 can be designed essentially identically, which is economically advantageous. In the illustrated embodiment, they each have a single sealing lip 22, which is curved and, in a use configuration, rests against the respective front surface 104 with elastic deformation.

[0064] A perspective view of a model window arrangement 100 with the base seal 1 from Fig. 1 shows Fig. 2 , wherein a window including the window frame 101 and the window base 102 located underneath, which is in Fig. 2 is concealed by a window tread 103 and therefore not visible, is inserted into a window opening of a building. For illustrative purposes, the double-leaf masonry, i.e., the facing 109 and the backing 108, as well as the insulation layer 107, are only indicated.

[0065] Shown is a facing 109 in the manner of a brick or clinker wall of a building wall, wherein the facing 109 is arranged outside in front of an insulation layer 107, which in turn is located outside in front of a backing wall 108. On a base plate 106, which is present, for example, in the form of a basement ceiling or a floor ceiling of the building, there is the base seal 1, the floor surface 3 of which lies on the aforementioned base plate 106 and the reveal surface 4 of which runs parallel to the window reveal and the wall surface 5 of which runs parallel to the wall of the building, i.e. parallel to the planes in which the facing 109, the insulation layer 107 and the backing wall 108 extend.

[0066] A perspective view of a second embodiment of a base seal 1 on the inside shows Fig. 3a and points to the outside Fig. 3b . It is important that the base seal 1 is now provided with a flat seal 23.

[0067] As in the first example from Fig. 1 show the Fig. 3a und 3b a base seal 1, which is designed as a room corner and has three seamlessly connected surface sections, namely with a floor surface 3, a reveal surface 4 and a wall surface 5, the wall surface 5 being approximately L-shaped, with a lower, horizontal section 5a, which in the position of use of the base seal 1 is located below a window step rail 103 of a floor-to-ceiling window, and with an upright, upper, standing section 5b, which as a narrow strip adjoins the lower, horizontal section 5a at the bottom and the reveal surface 4 at the sides. A flat seal 23 is glued onto these two sections of the wall surface 5, which run at an angle to one another.

[0068] In the illustrated embodiment, the flat seal 23 extends upwards by 50 mm beyond the upper edge of the lower section 5a of the wall surface 5, and in the illustrated embodiment, it extends laterally by 35 mm beyond the edge of the upper section 5b of the wall surface 5 beyond the lower, lying section 5a.

[0069] In the illustrated embodiment, the flat gasket 23 is initially in the form of an EPDM sheet as a two-dimensional surface element. The flat gasket 23 is bent from its two-dimensional, flat shape around a single, upright bend line according to Fig. 3b bent at an angle so that it has a wall-side section 23a which lies against the wall surface 5 and is glued to it, and a reveal-side section 23b which lies against the reveal surface 4 of the base seal 1 and is glued to it.

[0070] In the illustrated embodiment, the flat seal 23 is self-adhesive and the areas with which its wall-side section 23a protrudes beyond the wall surface 5 are covered by a protective film 6. Fig. 4 shows a perspective view of the base seal 1 from Fig. 3 from inside the building into the corner of the room formed by the base seal 1. Easily recognizable, among other things, is the L-shaped design of the wall surface 5. In this installation situation, the window including the window frame 101 and window base 102 have not yet been mounted or inserted. Nevertheless, the base seal 1 is shown here in its final position, so that the reveal surface 4 rests against the backing wall 108 and the floor surface 3 rests against the base plate 106. Once the base seal 1 has been attached to the base plate 106 and to the backing wall 108 by means of screws and adhesive, the protective film 6 can advantageously be removed from the flat seal 23 and the protruding area of ​​the wall-side section 23a and the reveal-side section 23b can be pressed against the respective front surfaces 104 of the window frame 101 and / or the window base 102 and adhesively bonded to them to form a seal.

[0071] Furthermore, in Fig. 4 an outer seal 24 is slightly visible. Due to pressure, the outer seal 24, applied as a sealing compound, can be seen as a projection that protrudes laterally beyond the edges of the floor surface 3 and the reveal surface 4. In addition, Fig. 5 the same installation situation as in Fig. 4 from a slightly different perspective, whereby Fig. 5 For illustration reasons, the base seal 1 is not shown so that a view of the outer seal 24 is possible.

[0072] Deviating from the illustrated embodiments, the standing upper section 5b of the wall surface 5 can be omitted, so that the wall surface 5 consists exclusively of the lower section 5a shown in the drawing. In this case, the wall-side section 23a of the flat seal 23 protrudes from the Fig. 3b right edge of the reveal surface 4 from where it does not lie against the lower, lying section 5a of the wall surface 5.

[0073] Fig. 6 shows a perspective view of a window arrangement 100 with the base seal 1 from Fig. 3 , whereby for the following designs, mutatis mutandis, a base seal 1 with sealing profile 20 can also be provided. For illustrative purposes, the cladding 109 is partially hidden.

[0074] The base seal 1 is shown in its final position. The flat seal 23 lies against the front surfaces 104 of a window frame 101 and a window base 102, with the front surfaces 104 running in the same plane. In contrast to the first embodiment of the Fig. 2 is in Fig. 6 shown that the window frame 101 has a roller shutter guide 105 on its front surface 104. In comparison to many window designs known from practice, Fig. 6 the roller shutter guide 105 is mounted on the window frame 101 offset inwards, i.e. closer to the window sash or closer to the pane, in Fig. 6 to the right. In this way, the outside of the roller shutter guide 105, in Fig. 6 i.e. to the left of the roller shutter guide 105, space is provided on the front surface 104 of the window frame 101 in order to allow the upright surface seal 23 of this front surface 104 of the window frame 101 to rest there.

[0075] The roller shutter guide 105 points to the opposite roller shutter guide 105, which is in Fig. 6 not shown, a longitudinal groove on (in Fig. 6 not visible), which serves to guide the roller shutter curtain. The wall-side section 23a of the flat seal 23 protrudes outwards, in Fig. 6 to the left, surprisingly slightly beyond the roller shutter guide 105. Based on the portion of the flat seal 23 that is visible below the roller shutter guide 105, it becomes clear that the flat seal 23 appears to be partially concealed by the roller shutter guide 105.

[0076] For this purpose, the roller shutter guide 105 is provided with a recess 110 in its lower area, whereby the upright section of the flat seal 23 extends into this recess 110 and is therefore partially concealed by the roller shutter guide 105. The recess 110 therefore enables the arrangement of the base seal 1 and sealing of the upright flat seal 23 on the front surface 104 of the window frame 101, even in confined spaces.

[0077] Another perspective view of the window arrangement 100 from Fig. 6 show the Fig 7a und 7b . After inserting the window, it is recommended to press the flat seal 23 onto the front surface 104. However, the facing 109 in particular covers the upright section of the flat seal 23 ( Fig. 7a ). Therefore, it is particularly advantageous to use a pressing tool 111 with a pressure section which is designed as an elongated flat doctor blade. Fig. 7b shows how, by means of a pressing tool 111, the flat seal 23 can be pressed into the gaps of a multi-layer masonry, or in the gaps between the masonry and the window, or in the recess 110 of a roller shutter guide 105, in order to be able to effectively apply the flat seal 23 to the front surface 104 even when the seal 2, in particular the flat seal 23, is directly covered by the masonry and / or by a roller shutter guide 105. For illustration purposes, the facing 109 is in Fig. 7b partially hidden.
