Description

[0001] The present invention relates to a window sill system and a closing unit, in particular for use in window and door openings and for covering wall sills.

[0002] Window sill systems and corresponding end units for securing a window sill to the side are well known in the art. Different window and door openings with appropriate plastering or insulation, or the installation of the window sill system against bare masonry, exposed concrete, or clinker brick exterior surfaces, place different demands on the corresponding window sill system and its end unit. Compensating for the longitudinal expansion of the window sill due to temperature differences in the area of the end unit has proven particularly difficult on exposed concrete and clinker brick exterior surfaces.This is because on these external surfaces in the area of the window or door opening, no length-compensating area of the finishing unit can be plastered in, but the finishing unit must be placed more or less directly and without play against the respective wall and fastened there.

[0003] The object of the present invention is to provide a window sill system and a closure unit that enables simple installation and reliable compensation for length changes in the window sill due to temperature changes, even for clinker brick exterior surfaces or similar types of exterior surfaces in the area of a door or window opening or on wall ledges. It is also the object of the present invention to design the closure unit in such a way that other requirements for window sill systems, such as, in particular, the required resistance to driving rain, are also met.

[0004] These objects are achieved with a closure unit according to claim 1 and a window sill system according to claim 13.

[0005] According to the invention, a closure unit is provided, in particular for use in a window sill system, comprising a profile element and a holding element, wherein the profile element has a first vertical profile part which extends substantially parallel to a plane spanned by a longitudinal direction and a vertical direction, wherein the profile element has a first profile projection and a second profile projection which, starting from the vertical part, extend predominantly along a plane spanned by the longitudinal direction and a transverse direction and are spaced from one another parallel to the vertical direction, wherein the holding element has a vertical holding part which extends substantially parallel to the plane spanned by the longitudinal direction and the vertical direction, wherein the holding element forms a receiving space,in which the profile element is partially received and secured against displacement at least in a direction parallel to the vertical direction. The core components of the closure unit are a profile element and a retaining element, which are particularly designed to ensure a floating support of a window sill relative to a masonry or window surround. The retaining element is particularly intended and designed to be fixed to the masonry. In preferred embodiments, this is achieved by plastering or gluing the retaining element to the masonry. Particularly in the case of unplastered exterior surfaces of the masonry, it is advisable to glue the retaining element; in this way, plaster, which can enclose both the wall and the retaining element, can be dispensed with. In order to ensure, despite the retaining element being firmly connected to the masonry,In order to compensate for thermal expansion in the window sill by the closure unit, a floating mounting of the profile element on the retaining element is provided. For this purpose, the retaining element forms a retaining space into which the profile element can be inserted, although a play for displacement along a transverse direction remains between the profile element and the retaining element. The retaining element thus preferably secures the profile element against displacement along or parallel to a vertical direction. The profile element, in turn, is designed to be fixed to a window sill in a form-fitting and, in particular, preferably also a force-fitting manner. For this purpose, the profile element has a first profile projection and a second profile projection which extend essentially in or parallel to a plane spanned by the longitudinal direction and the transverse direction, i.e., in other words, essentially horizontally.extend. Within the scope of the present invention, geometric features which are described as essentially should be understood to mean that the predominant part of the respective section or element extends along or in the corresponding direction or in the corresponding plane or parallel to the corresponding plane. This means that the corresponding geometric features which are described, for example, with an essentially parallel extension, can also have comparatively small extension components in other directions. Furthermore, the longitudinal direction, the transverse direction and the vertical direction are preferably perpendicular to one another and thus form the three main axes of a three-dimensional space. The first and the second profile projection of the profile element are designed in particular to be non-positively connected to the top and bottom of a window sill,by elastic deformation of the profile element's manufacturing material, so that the window sill can be arranged in a fixed position relative to the profile element. Furthermore, the profile element has a third profile projection, which is arranged in particular in the receiving space of the retaining element and thus achieves the floating support of the profile element on the retaining element. In this way, the fastening of a window sill via the end unit is also possible on clinker brickwork, whereby the thermal expansion of the window sill can be compensated for by the play between the profile element and the retaining element.

[0006] According to one embodiment, the receiving space of the holding element is formed by a C-shaped section of the holding element, wherein the profile element has a third profile projection which extends predominantly along the plane spanned by the longitudinal direction and the transverse direction and projects into the C-shaped section. The holding element is advantageously an extruded profile, particularly preferably made of an aluminum alloy. For such a profile, the formation of a section with a C-shaped cross section is particularly easy to achieve, thereby enabling very cost-effective production of the holding element. The C-shaped section encloses the third profile projection of the profile element in preferably three spatial directions. In this way, a stable securing of the profile element to the holding element can be achieved, wherein the profile element can be pushed into the holding element along the longitudinal axis.Together with the profile element's attachment to the window sill and its usual attachment to the masonry, especially below a door or window opening, the profile element is thus secured. The proposed solution, with a profile element that can be inserted longitudinally into a retaining element and removed again from the retaining element, enables a removable end unit and window sill attachment.

[0007] According to one embodiment, the third profile projection overlaps the C-shaped section with an overlap length that is greater than a greatest distance between the first vertical profile part and the vertical holding part, wherein the overlap length is preferably a multiple of a greatest distance between the first vertical profile part and the vertical holding part. The overlap length between the third profile projection and the C-shaped section of the holding element is advantageously at least as large, but particularly preferably greater, than the expected maximum thermal expansion carried out by the window sill. In relation to the closing unit, the overlap length is advantageously greater than the maximum play between the first vertical profile part and the vertical holding part parallel to the transverse direction.Particularly preferably, the ratio of the overlap length to the maximum distance measured along the transverse direction between the first vertical profile part and the vertical support part is in the range of 1.2 to 3, and preferably in the range of 1.3 to 2. In this way, a secure arrangement of the profile element on the support element can be achieved even in the event of large temperature differences, which lead to significant thermal expansion or shrinkage of the window sill. Furthermore, this sufficient overlap length also absorbs wind loads on the window sill, which in turn can result in significant displacement of the profile element relative to the support element in the transverse direction.

[0008] According to one embodiment, the holding element with the C-shaped section and the vertical holding part and the area between these two sections forms a channel-shaped profile with a cross-section that is essentially constant along the longitudinal direction. The channel-shaped profile formed by the holding element serves in particular for the controlled drainage of water that could get into the area between the holding element and the profile element and in particular in the area between the windowsill and the holding element. The C-shaped section, which is located at a first end of the holding element that is distal in cross-section, thus fulfills a dual function. Firstly, the C-shaped section secures the profile element against slipping out of the floating support.On the other hand, together with the vertical holding part arranged at the distal end of the holding element as seen in the other cross-section, the C-shaped section forms a channel which allows water to drain away.

[0009] According to one embodiment, a fastening element is provided which has at least a first vertical fastening part which extends substantially along the plane spanned by the vertical direction and the transverse direction, and wherein the fastening element has at least one transverse fastening part which extends substantially along the plane spanned by the longitudinal direction and the transverse direction, wherein the fastening element partially encloses and holds the holding element on its side facing away from the profile element. In this preferred embodiment, the holding element is therefore not exclusively fastened directly to the masonry, but the fastening element ensures further fixing of the holding element to the masonry. The fastening element is advantageously fastened to the holding element at the distal end thereof, which is arranged closest to the masonry.The first vertical and the transverse fastening part enclose the distal end of the retaining element in such a way that it is secured against displacement relative to the fastening element in at least two spatial directions. In addition to the direct fixation of the retaining element to the masonry in the area of the vertical retaining part, the fastening element can also provide additional fastening of the retaining element to the masonry.

[0010] According to one embodiment, the fastening element has a wall flange which extends substantially parallel to a plane spanned by the transverse direction and the vertical direction and is formed integrally with the fastening parts or is fixed to the fastening parts, wherein the wall flange has at least one engagement geometry for the engagement of an engagement means. The wall flange of the fastening element is advantageously a flatly extending region which is designed in particular for fastening the fastening element to the region of the wall below a window or a door opening. An additional engagement means, such as a screw or a bolt, is usually used to fasten the fastening element.In this way, the fastening element can be fixed in place to the masonry via the wall flange, whereby the engagement geometry can be used to achieve a positive and force-fitting fixation of the fastening element.

[0011] According to one embodiment, the fastening element has at least one reinforcing strut which extends between the wall flange and at least one of the vertical fastening parts essentially parallel to the plane spanned by the longitudinal direction and the transverse direction. In order to increase the stability of the fastening element, a strut is provided which extends between the wall flange and at least one of the vertically oriented fastening parts. The front edge of the strut is advantageously at an angle of 30° to 60° to the plane spanned by the vertical direction and the transverse direction. The strut can also have a rounded geometry or an essentially arcuate extension, in particular to avoid stress peaks in the area of sharp edges when forces are applied.

[0012] According to one embodiment, the fastening element has a fastening flank, which is designed and arranged at a distance from one of the first vertical, second vertical and / or transverse fastening parts in such a way that a gap is formed for the positive and preferably non-positive reception of the holding element, wherein the fastening flank is preferably L-shaped when viewed along the longitudinal direction. The fastening flank is advantageously designed as a further projection formed on the fastening element, which particularly preferably protrudes from a part of the fastening element that extends along the plane spanned by the transverse direction and the vertical direction.The fastening flank preferably runs parallel to the first vertical fastening part and to the transverse fastening part, such that a gap is formed between the fastening flank and the respective fastening part, into which gap a distal end of the retaining element can be inserted, in particular to be connected to the fastening element in a form-fitting and / or preferably force-fitting manner. In this way, the securing of the retaining element to the fastening element can be reinforced. Alternatively, or additionally preferred, the retaining element could also be secured to the fastening element by means of an adhesive or soldered connection or by means of a local weld.

[0013] According to one embodiment, a sealing strip is provided which is arranged in a space formed between the holding element and the profile element and is preferably clamped between the profile element and the holding element in such a way that support of the profile element on the holding element is achieved. The sealing strip seals the C-shaped section of the holding element and thus prevents unwanted corrosion or germ formation there. Alternatively or additionally, the sealing strip presses the third profile projection against the C-shaped section of the holding element and in particular dampens movements of the profile element relative to the holding element. In this way, the sealing strip can effectively prevent rattling of the end unit due to undamped relative movements of the profile element relative to the holding element, for example in windy conditions.

[0014] According to one embodiment, a surface element is provided which can be inserted into a gap formed between the vertical holding part and the first vertical profile part. The surface element is made of elastically deformable material, preferably rubber, silicone, foam rubber, or foamed silicone, in order to seal the gap and thereby cushion relative movements between the profile element and the holding element. To seal the gap between the first vertical profile part and the vertical holding part, a surface element is provided which is preferably designed as a flat and essentially cuboid-shaped element and achieves additional damping and sealing between the profile element and the holding element.The surface element itself can be designed to be elastically deformable in such a way that the surface element can also absorb and to a certain extent compensate for any longitudinal expansion of the window sill when temperatures change.

[0015] According to one embodiment, a protective element is provided which has a clamping section for fastening in the region of the upper edge of the first vertical holding part, wherein the protective element further has a protective section extending substantially parallel to the plane spanned by the longitudinal direction and the transverse direction. The protective element is an additional body which can preferably be subsequently secured at a selected position on the upper edge of the first vertical holding part. To simplify assembly, the protective element is preferably clamped onto the upper edge of the first vertical holding part and, for this purpose, has a corresponding slot-shaped receiving geometry for the upper edge of the holding element.Furthermore, the protective element has a flat area extending substantially parallel to the plane spanned by the longitudinal and transverse directions, which provides local coverage of the profile element and the connection area between the profile element and the window sill. This coverage may be desired or necessary, for example, if insulation material is to be subsequently installed in the area of the window or door opening. Alternatively or additionally, a roller shutter rail can be placed on the protective element, and in particular its protective section, to be supported there and closed at the bottom.

[0016] According to a further aspect of the invention, a window sill system is provided, comprising a closure unit according to the previous description and a window sill, wherein the window sill is inserted into a clamping gap formed between the first profile projection and the second profile projection and is held on the profile element in a substantially frictional manner. The window sill system thus consists of the previously described closure unit and a window sill, which is inserted into the clamping gap between the first and second profile projections and is held there preferably in a frictional and positive manner.

[0017] In one embodiment of the window sill system, the holding element and the fastening element are fixed to one another in a form-fitting and / or force-fitting manner, wherein the assembly of holding element and fastening element can be arranged and fixed essentially stationary relative to a masonry, wherein the assembly of window sill and profile element is mounted in a floating manner relative to the assembly of holding element and fastening element along the transverse direction. The assembly of window sill and end unit is thus secured relative to the masonry by fixing the fastening element to the masonry and its connection to the holding element as a whole. However, lateral movements of the window sill together with the profile element relative to the assembly of holding element and fastening element are still possible in order to compensate for temperature variations on the window sill.

[0018] Further advantages and features of the present invention will become apparent from the following description with reference to the accompanying figures. Individual features explicitly illustrated and identified in only one figure may also be used in embodiments of other figures, unless this is prohibited due to technical circumstances or explicitly excluded.

[0019] They show: Fig. 1 - a view of an embodiment of a window sill system, Fig. 2 - two views of an embodiment of a composite comprising a fastening element and a holding element, Fig. 3 - a view of components of a window sill system, Fig. 4 - two views of an embodiment of a fastening element, Fig. 5 - a perspective view of an embodiment of a window sill system, and Fig. 6 - a perspective view of another embodiment of a window sill system.

[0020] The Fig. 1, a window sill system 1 comprises a closing unit 2 and a window sill F. The closing unit 2 in turn comprises a profile element 4, a holding element 5, and a fastening element 6. The window sill F is held in a clamping gap 48 which is formed between a first profile projection 44 and a second profile projection 45 on the profile element 4. In other words, the window sill F is preferably pressed or driven into the clamping gap 48 of the profile element 4 with such great force that the profile element 4 and the window sill F can be regarded as a firmly connected unit. The profile element 4 itself is in turn mounted in a floating manner between a vertical holding part 52 and a C-shaped section 54 of the holding element 5, i.e. movements of the profile element 4 relative to the holding element 5 are possible along the transverse direction Q.The C-shaped section 54 of the holding element 5 preferably encloses a holding space 53 in which the third profile projection 46 of the profile element 4 is arranged. The floating support thus achieved serves in particular to compensate for temperature expansion. Furthermore, a sealing strip 7 is inserted between the profile element 4, particularly preferably between the third profile projection 46 of the profile element 4 and the holding element 5, which achieves damping, sealing, and / or a certain prestress between the profile element 4 and the holding element 5. The fastening element 6 of the present embodiment has a fastening flange 61, which is equipped with two engagement geometries 61A, preferably in the form of an elongated hole. The fastening flange 61 thus serves for positive and non-positive fastening to a masonry.The fastening element 6 has a first vertical fastening part 62 and a transverse fastening part 64, as well as a second vertical fastening part 63, which enclose the holding element 5 in such a way that it is secured against displacement relative to the fastening element 6 in a substantially form-fitting manner.

[0021] Fig. Fig. 2 shows two views of an embodiment of the assembly comprising a fastening element 6 and a holding element 5. The fastening element 6 preferably has a reinforcing strut 65, which in particular prevents bending between the wall flange 61 and the remaining areas of the fastening element 6. In addition to the Fig. 2, in which the reinforcing strut 63 extends between the second vertical fastening part 63 and the wall flange 61, the reinforcing strut 65 can also extend beyond this area between the wall flange 61 and the first vertical fastening part 62, which results in greater reinforcement, but also involves greater material usage and weight. Preferably, the fastening element 6 has a fastening flank 66, which forms a gap between the first vertical fastening part 62, the transverse fastening part 64 and preferably also between the second vertical fastening part 63. In this gap, the holding element 5, as in Fig. 2, in order to be fixed positively and preferably also force-fittingly to the fastening element 6.

[0022] Fig. 3 shows a further view of individual components of a window sill system 1 and particularly illustrates the feature of the overlap U between the third profile projection 46 and the C-shaped section 54. Within the scope of the present invention, this overlap U is preferably greater than or even a multiple of the distance A between the first vertical profile part 42 and the vertical holding part 52. In other words, the overlap U is thus preferably greater than the maximum play provided to compensate for temperature variations between the profile element 4 and the holding element 5. The size of the overlap U compared to the distance A therefore ensures secure floating mounting of the profile element 4 on the holding element 5.

[0023] Fig. 4 shows, similar to the embodiment in Fig. 2, two views of an embodiment of a fastening element 6. In this case, an L-shaped fastening flank 66 is preferably formed as an integral projection on the fastening element 6.

[0024] Fig. 5 shows a perspective view of a preferred embodiment of a window sill system 1. In this embodiment, a surface element 8 is inserted between the holding element 5 and the profile element 4, which is arranged and supported in particular between the first vertical profile part 42 and the vertical holding part 52. The surface element 8 ensures, on the one hand, dampening of movements between the profile element 4 and the holding element 5 and, on the other hand, advantageously also seals the gap formed between these two components.

[0025] Fig.6 finally shows a further preferred embodiment of a window sill system 1. In this case, a protective element 9 is fixed to the holding element 5 and, with its protective section 94, preferably covers an area of the closing unit 2 and the window sill F. In order to ensure that the protective element 9 can be fixed to the closing unit 2 in a simple manner and can be freely selected by the respective fitter during assembly, the protective element 9 has a clamping section ninety-two which can be easily plugged onto the vertical holding part 52 and is fixed there in a force-fitting and form-fitting manner.
