Description

The present invention relates to a window sill system and a closure unit, in particular for use in window and door openings and for covering masonry messages.Window bank system and corresponding termination units for ensuring the definition of a window bank in the side region are sufficiently known from the prior art. In this case, for different windows and door openings with a suitably provided plastering or insulation, or the contact of the window sill system with a bare masonry, a visible concrete or a clinker outer surface, different requirements are imposed on the corresponding window sill system and its closure unit. Especially with visible concrete and clinker outer surfaces, it has been found to be difficult to be able to compensate for the longitudinal expansion of the window sill in the event of temperature differences in the region of the termination unit. This is due to the fact that no length-compensated region of the closure unit can be cleaned on these outer surfaces in the region of the window opening or door opening, but rather the closure unit has to be placed more or less directly and without play on the respective wall and fastened there.It is an object of the present invention to provide a window sill system and a termination unit which also allows simple assembly and reliable compensation of changes in length of the window sill in the event of temperature changes for clinker outer surfaces or similar types of outer surfaces in the region of a door or window opening or on masonry side walls. It is a further object of the present invention to design the termination unit in such a way that further requirements for window bank systems, such as in particular the required impact rain tightness, are also fulfilled.According to the invention, a termination unit is provided, in particular for use in a window sill system, having a profile element and a sealing element, wherein the profile element has a first vertical part which extends substantially parallel to a plane spanned by a longitudinal direction and a vertical direction, wherein the profile element has a first retaining projection and a second retaining projection which, starting from the vertical part, extend substantially parallel to a plane spanned by the longitudinal direction and a transverse direction and are spaced apart from one another, wherein the sealing element has a sealing section which can be fixed, preferably plugged, to a distal end of the first retaining projection remote from the first vertical part. The essential components of the termination unit are a profile element, which preferably extends with a substantially constant cross section along a longitudinal direction, and a sealing element, which is fixable or fixed to the profile element. The term "substantially" always expresses, within the scope of the present application, that a predominant part of the feature described in each case, i.e. its principal or predominant regions, should have the correspondingly defined feature. If the vertical part of the profile element is therefore intended to extend substantially parallel to a plane spanned by a vertical direction and a longitudinal direction, this means that the predominant part of the vertical part extends parallel to this plane and also has the greatest extension parallel to this plane. This definition is intended to apply to all of the features identified as "substantially.". The particular feature of the present end unit is that the sealing element and the profile element are connected to one another in a manner which enables simple assembly and which at the same time permits optimized contact of the end unit on a wall, wherein the end unit itself enables a sliding mounting of a window sill. For this purpose, the sealing element is fixed with its sealing section on the first retaining projection of the profile element of the form-fit. At the same time, in this region of the distal end of the holding projection, a receiving gap is formed into which the window bank can be slidingly inserted. This makes it possible to arrange the profile element directly or indirectly, i.e. for example with the damping element located therebetween, on a wall and to fix it in a materially bonded or positive-locking manner, for example. The plane spanned by the longitudinal direction and the transverse direction advantageously corresponds exactly to the plane within which the largest portion of the window sill extends in terms of area.In one embodiment, the sealing element has a base section which extends substantially parallel to the plane spanned by the longitudinal direction and the transverse direction and on which the sealing section is formed in one piece. The base section of the sealing element serves here on the one hand for positioning the sealing section and on the other hand it represents a bridge to further regions of the sealing element, which will be described below. The base section extends here in a planar manner and substantially parallel to the plane spanned by the longitudinal direction and the transverse direction. In this case, the base section can be arranged on the underside of the profile element in such a way that a damping function is achieved when the termination unit is placed on a masonry wall.In a further embodiment, the sealing element has a wall contact which is formed integrally with the base section and extends substantially orthogonally to the plane spanned by the longitudinal direction and the transverse direction, wherein the wall contact makes a planar contact on the first vertical part and / or on a second vertical part of the profile element and covers this or these in regions. The wall contact of the sealing element serves in particular for sealing and damping off between the profile element and the masonry or adjacent window or door components. In a first embodiment, it is preferred that the wall support extends over the entire intermediate region, i.e. over the entire surface of the first vertical part of the profile element, and thus supports and dampens the profile element completely with respect to the wall. In a further embodiment, the wall system can fill only a partial region between the vertical part and the masonry and thus achieve local support. This is preferred and necessary in particular when the profile element is to be glued to the wall in the region of the first vertical part of the latter, and a larger adhesive surface must be available in the process.In a further embodiment, the wall contact has a first wall contact section and a second wall contact section, which extend substantially orthogonally to one another and come to lie flat against a respective vertical part of the profile element. The wall contact of the sealing element is a form of sealing section of spaced-apart region which extends substantially vertically and thus orthogonally to the plane spanned by the longitudinal direction and the transverse direction. In this case, the wall contact serves in particular for sealing and damping between the masonry and the profile element. As already described above, the base section of the sealing element serves as a connecting bridge between the wall contact and the sealing section.In a further embodiment, the material of the sealing element comprises rubber and / or silicone. In particular, in order to be able to perform the sealing function and damping function in a particularly optimal manner, the sealing element is made of flexible material such as rubber and / or silicone, for example. A combination of the two materials is particularly suitable in order to be able to use silicone at the regions responsible for the sealing function, which is particularly conformable because rubber can be used in other regions, in particular for absorbing impacts. Particularly preferably, foamed variants of these materials can also be used which improve the weight, the elastic deformability and the thermal insulation.In a further embodiment, the sealing element and / or the profile element is / are formed as a one-piece body(s). In particular, in order to save costs, the sealing element with its various sections is preferably designed as a one-piece body. Likewise, the profile element can advantageously also be embodied in one piece in order to achieve a particularly high strength of the material and a low outlay on assembly.In a further embodiment, the profile element is an extruded metal body, and preferably made of aluminum. Extrusion methods have proven to be particularly cost-effective and stable variants for the production of the profile element. Aluminum, as a particularly readily extrudable material, is suitable for producing the profile element.In a further embodiment, the first vertical part of the profile element has a flange surface which is designed for the lateral bearing of the termination unit on a masonry and / or on a planar element, wherein the flange surface preferably extends only over a part of the extent of the profile element measured parallel to the longitudinal direction. It is preferred to design the flange surface of the profile element such that a particularly high surface is available for a preferably materially bonded fixing of the profile element to a masonry. It is therefore also preferred that the flange surface of the profile element is provided only where masonry is also present opposite the profile element. Therefore, the profile element can have a greater extension parallel to the longitudinal direction than the flange surface, which means in particular a saving in material.In a further embodiment, the first retaining projection extends at its distal end facing away from the vertical part obliquely to the transverse direction, wherein the direction of extension of the distal end encloses an angle of preferably 5°-20°, particularly preferably of 5°-10°, with the plane spanned by the longitudinal direction and the transverse direction. The preferred oblique extension of the retaining projection with respect to the plane spanned by the transverse direction and the longitudinal direction enables a self-reinforcing effect to be achieved when the sealing section is fastened to the distal end of the retaining projection. Thus, the sealing section can be pushed onto the distal end when the window bank is not yet mounted. As soon as a window bank is then fixed to the closure unit, it prevents the sealing section from slipping down from the distal end of the retaining projection, and the sealing element is thus fixed particularly firmly to the profile element.In a further embodiment, the sealing section has two sealing lips which define a V-shaped cross section of the sealing section. The use of a double sealing lip improves in particular the sealing effect of the sealing section. Furthermore, by means of the sealing lip facing in the direction of the vertical part, the receiving region of the sealing section is formed in a particularly simple manner for fixing to the distal end of the first holding projection. The outwardly projecting sealing lip, i.e. the sealing lip projecting in the direction of the window bank center, however, achieves a particularly high sealing effect with respect to moisture located below the window bank.In a further embodiment, a channel is formed between the first and the second retaining projection, which channel has a minimum extension parallel to the vertical direction, which is at least twice the extension of the first retaining projection or of the second retaining projection parallel to the vertical direction. The channel formed between the first and the second retaining projection serves in particular to allow water penetrating into the edge regions of the window sill to flow off in a controlled manner forwards and thus away from the masonry and the bottom side of the window sill.In a further embodiment, the first vertical part has a local recess, in which the sealing element is fitted in the region of the wall contact. The local recess on the profile element serves in particular to achieve a continuous and substantially planar surface on the underside of the profile element when the sealing element is inserted. Furthermore, the sealing element is preferably positively secured in the local recess against movements along a plane, which facilitates the assembly of the termination unit.In a further embodiment, the extension length of the profile element and / or of the sealing element parallel to the longitudinal direction is a multiple of the extension length parallel to the transverse direction and to the vertical direction, wherein a multiple is preferably 2 to 12 times, and particularly preferably 4 to 8 times. It has been found that the length ratio of the longitudinal extension (i.e. measured along the longitudinal direction) is in a preferred ratio of 2-12 to the width of the profile element (i.e. measured parallel to the transverse direction) in order on the one hand to create a sufficient compensation space for longitudinal extension in the window sill and on the other hand to keep the weight of the overall arrangement as low as possible. The particularly preferred ratio of 4-8 has proven to be a particularly stable embodiment of a profile element.In a further embodiment, a protective element is provided which has a clamping section for fastening in the region of the upper edge of the first vertical part, wherein the protective element furthermore has a protective section which extends substantially parallel to the plane spanned by the longitudinal direction and the transverse direction. The protective element is an additional body, preferably fixable subsequently and at a selected position on the upper edge of the first vertical part of the profile element. To simplify assembly, the protective element is preferably clamped firmly on the upper edge of the first vertical part and for this purpose has a corresponding slot-shaped receiving geometry for the upper edge of the profile element. In addition, the protective element has a region which extends in a planar manner and substantially parallel to the plane spanned by the longitudinal direction and the transverse direction and which achieves a local covering of the profile element and of the connection region between profile element and window sill. This cover may be desired or necessary, for example, if insulating material is to be subsequently applied in the region of the window or the door opening.In a further embodiment, the sealing element has an engagement geometry at the end of the wall contact facing away from the base section, which engagement geometry at least partially encompasses the upper edge of the first vertical part and / or of the second vertical part of the profile element. In this preferred embodiment, on which the wall contact of the sealing element extends between the masonry and the first vertical part of the profile element, it is particularly preferred that the wall contact comprises the upper edge of the vertical part of the section. In this way, a positive fit is achieved between the sealing element and the profile part, which enables an improved preassembly of the termination unit. On the other hand, an improved seal is achieved since water penetrating between the sealing element and the profile element can be reduced.In a further embodiment, a sealing bead is formed on the wall contact of the sealing element, which sealing bead is preferably filled with air or a softer material than the production material of the remaining regions of the sealing element. Particularly preferably, the sealing bead is filled with a sponge rubber. The sealing skin extends preferably parallel to the transverse direction or parallel to the longitudinal direction on the wall contact section provided in each case. Thanks to the sealing bead, a reliable seal can nevertheless be achieved, in particular in the case of large unevennesses in the masonry.According to the invention, a window bank system is furthermore provided, comprising an above-described termination unit and a window bank, wherein the window bank is inserted into a holding gap formed between the sealing section and the second holding projection and is held there. As already described above, the window bank of the window bank system is held in the holding gap formed between the first holding projection and the second holding projection. In this case, on the side of the first holding projection, the sealing section is also added, which preferably achieves an additional clamping function and sealing on the underside of the window sill.In one embodiment, a surface element is provided on which the termination unit comes to bear with at least a part of the flange surface, wherein the surface element is formed from elastically deformable material and is provided on its side facing away from the termination unit for bearing on a masonry. Alternatively or additionally to a wall contact of the sealing element, a surface element is provided, which is preferably designed as a planar and substantially cuboidal element and achieves additional damping and sealing between the termination unit and the masonry. The surface element itself can be designed to be elastically deformable in such a way that the surface element can also absorb a longitudinal expansion of the window bank in the event of temperature changes and to a certain extent can compensate for it. In addition, the surface element can preferably be equipped with an adhesive-impregnated material, which enables a particularly simple and permanent fastening of the closure unit to the masonry.Further characteristics of the present invention will become apparent from the following description with reference to the attached figures. The following are shown: FIG. 1 is a perspective view of an embodiment of a window system according to the invention; FIG. 2 is a sectional view of the embodiment shown in FIG. 1; FIG. 3 is a perspective view of an embodiment of a sealing element; FIG. 4 shows two perspective views of an embodiment of a profile element; FIG. 5 shows a perspective view of an embodiment of a window system and its installation situation; FIG. 6 is a sectional view of another embodiment of a window system; FIG. 7 is a perspective view of another embodiment of a window system; and FIG. 8 shows a perspective view of a further embodiment of a window system with a corresponding installation situation.The window system 1 shown in FIG. 1 has a termination unit 2 and a window bank F, wherein the window bank F is fixed to the termination unit 2 here in the already mounted position. The end unit 2 has a profile element 4 which has, on its side facing the wall (not shown), a first vertical part 42 which projects upwards (i.e. in the vertical direction V, see FIG. 2 ) beyond the second retaining projection 46. The flange surface A is formed on the first vertical part 42 and is provided for fastening the profile element 4 to the masonry M or alternatively to a surface element 8 (see FIG. 8 ). In a further alternative embodiment, the flange surface A is designed to be fixed to the wall contact 66 of the sealing element 6, and in this case preferably to the first wall contact portion 66A. On its front side, the profile element has a front part 47, which is bent downward by approximately 90° and thus follows the shape of the window sill F and secures it against slipping out to the front, that is to say to the diagonally right bottom in the figure.FIG. 2 shows the embodiment shown in FIG. 1 in section. It can be seen here that the window sill F is pushed laterally into a holding gap 67 counter to the transverse direction Q. In this case, the window bank F is secured between the sealing section 64, which in turn is held on the first holding projection 44, and the second holding projection 46 against vertical displacements along or counter to the vertical direction and can slide laterally, that is to say along or counter to the transverse direction Q, as a result of which length changes of the window bank F can be compensated for in the event of temperature changes. Furthermore, a channel 48 is formed between the first holding projection 44 and the second holding projection 46, which channel allows water to flow off. The sealing section 64 advantageously has two sealing lips, one of which projects inward and one of which projects outward with respect to the channel 48, so that a corresponding seal can be achieved in both directions, i.e. along or counter to the transverse direction. In other words, the sealing section 64 has a v-shaped geometry in cross section. Furthermore, a corresponding recess is formed on the sealing section 64, with which recess the sealing section 64 can be pushed onto the distal end 45 of the first holding projection 44 and is held there. The distal end 45 is advantageously angled obliquely upwards, so that the sealing section 64 and thus the entire sealing element 6 is particularly held in place when the window sill F is inserted.Figure 3 is a perspective view of a preferred embodiment of a sealing element. It can be seen particularly well that the wall contact 66 in this embodiment has two planar regions, a first wall contact portion 66A and a second wall contact portion 66B in the latter covering the rear corner region of the profile element 4 in two directions. The base section 62 and the sealing section 64 of the sealing element 6 extend parallel to the longitudinal axis L with a substantially constant cross section.FIG. 4 shows two perspective views from different directions of one and the same embodiment of a profile element 4. in this case, in addition to the first vertical part 42 already described above, the second vertical part 43 can also be seen, which, similar to the second wall contact portion 66B of the sealing element 6 (see FIG. 3 ), extends substantially parallel to the plane spanned by the transverse direction Q and the vertical direction V. Particularly preferably, the second vertical part 43 extends substantially parallel to the front part 47 and, in the vicinity of the second vertical part 43, a local recess 49 is formed which serves for the positive-locking reception of the sealing element 6. As can be seen in FIG. 1, this ensures that the sealing element 6 and the profile element 4 each define a continuous, substantially planar surface on their underside.FIG. 5 shows a preferred embodiment of the window system 1 and its installation situation at a window opening. It can be seen here that on the underside the window bank and the termination unit 2 cover a window chamfer. Arranged laterally between the covering unit 2 and the masonry M (with plaster or clinker shown thereon) is a planar element 8, which is provided on the one hand for adhesion and on the other hand for additional sealing and damping. In this embodiment, the first vertical part 42 of the profile element 4 is preferably adapted to the size of the planar element 8 and in particular to the size of the contact region with the opposite masonry M. In other words, the remaining region of the profile element 4 thus projects forwards beyond the first vertical part 42 so that the window sill F together with the closure unit 2 project beyond the masonry M on the side shown at the bottom left. It is understood in this context that the termination unit 2 could also be fixed directly to the masonry M, wherein in this case no surface element 8 is present.FIG. 6 shows the embodiment shown in FIG. 5 in section, wherein in particular the details of the connection region between the masonry, the surface element 8 and the first vertical part 42 of the profile element 4 are shown. In this preferred embodiment, the sealing element 6 only has the base section 62 and the sealing section 64, wherein in this embodiment no wall contact 66 is thus formed on the sealing element 6.FIG. 7 shows a further preferred embodiment of a window system 1, wherein a protective element 9 is fixed to the termination unit 2. The protective element 9 has a clamping section 92 with which it is placed on the upper edge of the first vertical part 42 and fastened there. Furthermore, the protective element 9 has a region which extends in the shape of a roof and substantially parallel to the plane spanned by the longitudinal direction L and the transverse direction Q and which reaches a local covering. Furthermore, a varied embodiment of the sealing element 6 is shown, which has a fastening block 65 designed as a projection in the region of the wall contact 66. The fastening block 65 is also possible in the embodiments shown above and improves the engagement between the profile element 4 and the sealing element 6, and additionally stabilizes the sealing element 6 in the region of the wall contact 66.Finally, FIG. 8 shows a further preferred embodiment of a window system 1, in which, in addition to the protective element 9 and a surface element 8 which correspond to the embodiments described above, the sealing element 6 has an engagement geometry 68. The engagement geometry 68 protrudes beyond the first vertical part 42 of the profile element 4 and encloses or comprises its upper edge in regions. This firstly reinforces the positive connection between the sealing element 6 and the profile element 4. On the other hand, an improved sealing of this region can be achieved, since water penetrating between the profile element 4 and the sealing element 6 can be prevented. The composite of profile element 4, sealing element 6 and protective element 9 is finally placed on the surface element 8 and fastened indirectly via the surface element 8 to the wall. As already explained above, it is understood that in this embodiment the surface element 8 can be dispensed with, in particular when the lateral, first wall contact section 66A covers the entire width of the first vertical part of the 42. Furthermore, the sealing element 6 is preferably equipped with a sealing bead 69, at least in the region of the wall contact 66. It is understood that this sealing bead can preferably also be provided in further regions of the sealing element 6 and in particular of the wall contact 66. However, it has proved to be advantageous to arrange a sealing bead 69 in particular in the rear region of a window sill attachment, since the greatest unevennesses in the masonry are to be expected there, which can be compensated particularly well by the particularly soft configuration of the sealing bead 69.List of reference numbers:1 Window sill system 2 Termination unit 4 Profile element 6 - Sealing element 8 Surface element 9 Protection element 42 First vertical part 43 Second vertical part 44 First retaining projection 45 Distal end 46 Second retaining projection 47 Front part 48 Channel 49 Local recess 62 Base portion 64 Sealing portion 65 Engagement block 66 Wall abutment 66A First wall abutment portion 66B Second wall abutment portion 67 Retaining gap 68 Engagement geometry 69 Sealing bead 92 Clamping portion 94 Protection portion A Flange surface F Window sill M Masonry L Longitudinal direction Q Transverse direction V Vertical direction
