The invention relates to a system which has a frame for a window or a (patio) door, a shading system and a drainage element, with the following features:

1. a) the drainage element has a base plate and at least one tab which is arranged at an angle to the base plate and which is arranged on at least part of an edge of the base plate which, when the drainage element is installed, extends transversely to the window plane on an outer side of the window;
2. b) the tab has at least one fastening means;
3. c) the frame has at least two high strips,
4. d) a guide for a curtain of the shading system is arranged on at least two of the high strips,
5. e) the guides each have a base rail, characterized in that the tab of the drainage element has a shape corresponding to the base rail.

The invention also relates to a window or a (patio) door with a frame inserted into an opening in a building, which defines a window or door level, and with such a system.

Such a system and such a window or (patio) door are out of the DE 10 2015 218 344 A1 known.

Drainage elements for windows or (patio) doors, also known as cups or drainage modules in technical jargon, are used laterally under the outer ends of a window sill and serve to divert accumulating rainwater, especially in driving rain. At her rear, to the Window level parallel edge they have an upstanding tab by means of which they can be attached, for example, to a frame of a composite window. Such a drainage module is known, for example, as the "Delta" drainage module, product name PK 50/500, from Gutmann AG.

The applicant had developed a system in which a guide for a shading system is integrated into the frame of a composite window. This system is the subject of post-published DE 10 2018 106 055 A (corresponding EP 3 540 172 A1 ). The guide for the shading system is referred to below in a simplified manner as roller shutter guide, although other shading systems, such as horizontal blinds, are known from practice and can advantageously be used together with the new system. The known drainage elements are not sufficient for such a system. In particular, sufficient tightness against driving rain is not guaranteed in the lower corners of the window, so that rainwater can penetrate between the stick frame and the masonry.

That from the DE 10 2005 218 344 A1 The known drainage element has a base plate and a first strap formed thereon, which can be connected to the stick frame 31. This first tab extends parallel to the window plane. A second flap is attached perpendicular to the window level and has a further flap formed on it in a step-like manner. The first flap and the further flap are provided with slots in order to connect the drainage element to the pole frame. A complete tightness against driving rain is not given with this system either.

Proceeding from this, the invention was based on the problem of developing a system of the type mentioned and a window or a (patio) door of the type mentioned in such a way that, with simple assembly, the tightness, in particular against driving rain, is improved.

To solve this problem, the system according to the invention has the features of claim 1. The window according to the invention or the (patio) door according to the invention solves the problem on which the invention is based with the features of claim 15.

According to the invention, the tab with the fastening means is arranged on an edge which, when the drainage element is installed, extends across the window plane on an outer side of the window. By means of the tab, the drainage element is attached to a part of the window or door, specifically to the frame, with the aid of the fastening means. The system according to the invention is characterized in that the tab of the drainage element has a shape that corresponds to the base rail

In this way, the tightness in driving rain can be improved in a surprisingly simple manner. Tests have even shown that even when cleaning the window and cleaning with a high-pressure cleaner, no or at least hardly any water penetrates between the stick frame and the masonry. This reliably prevents water damage to the stick frame and the masonry. The tab only needs to be inserted into the base rail, which simplifies assembly.

Advantageous refinements of the invention are the subject of the dependent claims.

Thus, at least one connecting tab can be assigned to the tab. With the help of this connecting strap, the drainage element can be connected to a guide for a shading system in a structurally simple manner. For this purpose, the connecting strap can have a threaded hole, which is preferably provided in an integrally formed turning attachment. In this way, a screw, for example a grub screw as a clamping screw, can be screwed in in a simple manner and an attachment can thus take place by means of clamping.

Furthermore, the base plate can be assigned a second flap which extends at least on part of an edge adjacent to the edge for the first flap. This further improves the tightness.

Furthermore, the base plate can be designed in the manner of a hammer head or flag and provided with a draining surface. This improves the drainage of the water. It is particularly advantageous if a further tab is provided, which is then arranged on an end of the first tab opposite the second tab. This can be arranged adjacent to the draining surface. This is particularly advantageous for the above-mentioned new window frame with integrated roller shutter guide, since the roller shutter guide can be plastered over to improve the appearance. The additional tab prevents water from penetrating this layer of plaster. Any water that may collect under the roller shutter guide is reliably drained off via the draining surface.

A particularly good seal can be achieved if the first tab is integrally connected to at least one of the other two tabs. The first tab is particularly preferably connected in one piece to the two other tabs. It is also particularly advantageous in terms of production technology if the drainage element is designed as a whole as a one-piece plastic molded part.

So that rainwater that runs off the outside of the roller shutter guide or the plaster layer arranged on it is safely drained off, a channel can be provided on the base plate on the side of the further flap opposite the first flap. This channel then opens to the draining board. The channel is preferably delimited on its side opposite the further tab by a delimiting tab. In this way, the rainwater that drips off is reliably drained via the draining surface and kept away from the masonry. Furthermore, guide ribs can be provided on the base plate for further conduction of the rainwater.

According to a further independently conceivable further development of the invention which, under certain circumstances, is also advantageously used with the known drainage elements can be, a bracket for holding an end piece for a window sill is provided on the base plate. In this way, the end piece can be decoupled from the window sill, so that thermal expansion of the window sill no longer has any effect on the end piece. If the window sill expands under heat, the end piece is pressed more outward into the window reveal. This prevents cracks in the plaster.

A connection of the drainage element to the roller shutter guide, specifically its base rail, can be effected in a structurally simple manner, in that the at least one connecting strap engages in a dovetail-like manner in a corresponding groove in the base rail. The connection between the connecting strap and the groove can be made with a force fit, for example by means of a clamping screw. Additionally or alternatively, a clamping fit can be provided between the groove and the connecting strap.

In order to ensure a good drainage of water, which possibly penetrates into openings of the roller shutter guide due to the construction, the base plate should be designed like a hammer head or flag that the base plate extends at least over the entire depth of the base rail.

In the figures, parts of a transverse strip 10 and a high strip 11 of a window frame for mounting on a frame of a window or a (patio) door are shown. Such windows are known as wood-aluminum windows or plastic-aluminum windows. The cross bar 10 and the high bar 11 together with an upper cross bar and a further high bar form the frame, which is attached to the outside of the stick frame. A lower corner of the window frame is shown as an example. The frame or the stick frame together span a window level that is in the Figs. 1 to 4 is indicated by a cross arrow 12.

A base rail 13 for a shading system is attached, specifically plugged in, to the high bar 11. For this purpose, a receiving groove 14 is provided on the upright 11, into which a retaining tab 15 of the base rail 13 is inserted. The base rail 13 forms an integral part with the frame, like this one Subject of the post-published DE 10 2018 106 055 A (also registered as a European patent application with the application number 19 162 588.8 ) is.

A drainage element 16 is provided below the transverse strip 10 and the base rail 13. The drainage element 16 has a base plate 17 which is essentially delimited by four edges 18, 19, 20 and 21. The edge 18 is in the assembled state ( Figure 2 ) below the window frame, specifically the transverse strip 10, arranged. The edge 20 is opposite her. In the fully assembled state, the edge 19 is arranged to the side of the window and below the base rail 13. It is therefore referred to below as outer edge 19. The opposite edge 21 points inward. The edges 18 and 20 thus run approximately parallel to the window plane 12, while the edges 19 and 21 run approximately transversely to the window plane 12. For a good drainage of the water, the edges 19 and 21 slope outwardly away from the window.

On the outer edge 19, a tab 22 is arranged, specifically molded. This tab 22 is also referred to as a side tab 22 in the context of the present application. Furthermore, a further tab 23 is arranged, specifically formed on, on part of the rear edges 18, which is also referred to as the rear tab 23 in the context of the present application. The rear flap 23 terminates on one side with the outer edge 19 and can be connected to the flap 22 at a corner, in particular in one piece.

The side flap 22 has a shape corresponding to the profile of the base rail 13, as shown particularly well in FIG Fig. 4 is recognizable. Specifically, the base rail 13 is provided with a C-shaped groove 24 on each of its biting outer longitudinal edges. In each of these grooves 24, a T-shaped connecting tab 25 engages on the side tab 22 in a form-fitting manner. For this purpose, the C-shaped grooves 24 and the T-shaped connecting tabs 25 have a shape corresponding to one another. The connecting tabs 25 are dovetailed in the grooves 24.

The connecting tabs 25 are each also provided with a threaded bore 26, which in the present case is provided in a cylinder attachment 27 which is formed on the respective connecting tab 25. A screw, preferably a grub screw 28, is screwed into this threaded bore 26 and a non-positive clamping connection is thus established between the connecting straps 25 and the base rail 13. In addition or as an alternative, the connecting tabs 25 can also be provided with a certain oversize with respect to the grooves 24, so that a certain amount of clamping is achieved through the shape alone (analogous to a press fit). Of course, any other technically sensible type of connection for a connection between the base rail 13 and the side plate 22 is also possible.

In the area of the rear edge 18, specifically between the rear edge 18 and the rear flap 23, a channel 29 is provided in which, as in FIG Figure 2 recognizable, the frame, specifically its cross rail 10, engages. The rear flap 23 is arranged from the outside, that is to say from the edge 20, in front of the frame, specifically the cross rail 10. The rear flap 23 rests on the outside of the frame or the cross rail 10. In this area, there is no fixed connection between the window frame or the cross section 10 with the drainage element 16 and / or the base rail 13. However, such a connection can optionally be present as an additional connection.

Viewed from above, see, for example, the top view according to FIG Fig. 4 , the drainage element 16 or its base plate 17 has a hammer head or flag-like contour. In the area of the base rail 13, the base plate 17 protrudes only slightly over the base rail 13 forwards (opposite the window frame), while the base plate 17 protrudes further outside this area with a draining surface 30. The base plate 17 is provided in this area with an approximately rectangular notch 31, which, however, can also have an arcuate or other contour. In any case, the base plate 17 extends at least over the entire depth of the base rail 13 and thus the shading system. This applies both in the direction across the window plane 12 and seen parallel to the window plane 12.

As already stated in the preceding paragraph, the base plate 17 projects in the area of the notch 31 slightly over the depth of the base rail 13, specifically over an end leg 32 of the same. Below the end limb 32 and corresponding to it, a front flap 33 is provided on the base plate 17, specifically formed in one piece thereon. In this area, the base plate 17 protrudes further outward than this front flap 33, that is, away from the window, and has a delimiting flap 34 on the resulting edge, which in the present case extends parallel to the front flap 33. A channel 35 is formed between the front flap 33 and the limiting flap 34 and opens towards the draining surface 30. Rainwater or water that occurs during cleaning and hits against the front leg 32 can run off via this channel 35. In the case of a plastered-in base rail 13, the end leg 32 is provided with plaster. The channel 35 is dimensioned so that there is still enough space to accommodate dripping water.

In order to further improve the drainage of rainwater or water used for cleaning purposes, guide ribs 36, 37 are provided on the top of the base plate 17. How particularly good in Figure 4 It can be seen that first guide ribs 35 are arranged to run obliquely forward towards the edges 20 and 21. When the base rail 13 is mounted, these guide ribs 36 extend in the area below the base rail 13. Outside this area, that is, in the area of the base plate 17 pointing further towards the window center, second guide ribs 37 are provided which extend perpendicular to the window plane 12. They run parallel to the inner edge 21.

Another variant of a drainage element according to the invention is in Figures 5 to 8 shown. It is essentially the same as the drainage element 16 described above. The same parts are therefore denoted by the same reference symbols.

The side flap 22 is formed, together with the rear flap 23 and an inner side flap 38, in a U-shaped circumferential manner. In addition, the base plate 17 is free of ribs, but can also have the guide ribs 36 and 37 from the embodiment described above. Furthermore, especially in Figure 5 It is easy to see that a base 39 is formed in the region of the bracket 22, on which the base rail 13 rests in the assembled state. The front flap 33 forms part of this base 39, which corresponds overall to the contour of the base rail 13. The base rail 13 can therefore be supported on this base 39 or stand up on it. Such a base 39 can also be used in the previously described exemplary embodiments according to Figure 1 to 4 be provided.

Furthermore, especially in Figure 6 or 8th It is easy to see that a delimiting tab 34 is also provided, which together with the front tab 33 forms the channel 35, which in turn opens towards the draining surface 30. At its opposite end, as is also possible in the previously described embodiment, it is closed in particular by the tab 22. A notch analogous to notch 31 in the exemplary embodiment described above is also not present, but can be provided.

In the Figures 5 to 8 the base rail 13 is shown together with other, for example latched, rails attached to it, which together with the base rail 13 form the guide 40 for the curtain of the shading system. The outer end of a window sill 41 is also shown. As in Figure 7 As can be clearly seen, a certain gap remains between the lateral edge 42 of the window sill 41 and the guide 40, through which the thermal expansion of the window sill 41 can be compensated.

Additionally or alternatively to the drainage element 16 according to the embodiment according to the Figures 1 to 4 the present drainage element 16 has a bracket 43. The console 43 is cuboid. It can be designed to be hollow and, in particular, to be open at the bottom. The end face of the bracket 43 facing the rear flap 23 is aligned with the side face 44 of the limiting flap 34 facing the front flap 33 and together with this delimits the channel 35 to the outside (away from the window). Furthermore, one side surface is aligned 45, which faces the inner side flap 38, with a free end of the front flap 33. This side surface 45, together with the side flap 38, delimits the draining surface 30.

The base rail 13, specifically its end limb 32, is assigned an end piece 46 for the window sill 41. In the present case, the end piece 46 is fastened to the end leg 32 in a suitable manner. The cross section of the end piece 46 has a downwardly open U-profile, in the interior of which the console 43 is arranged in the assembled state. The console 43 carries the end piece 46. In this respect, a fixed connection between the end piece 46 and the base rail 13 is also not absolutely necessary. It is sufficient if the end piece 46 is attached separately to the console 43 and is only held by it. A clamp fit between the console 43 and the end piece 46 is again suitable for this.
