Definitions

  • the invention relates to a roof window with a blind frame and a sash frame carrying glazing of the roof window.
  • a first fluid opening and a second fluid opening are provided, which are fluidically connected to one another at least temporarily via a flow path, with the glazing being arranged in certain areas at a distance from a spar of the casement, so that a gap is formed and the flow path is at least in certain areas between the glazing and a spar of the casement runs.
  • the roof window is present, for example, in the form of a roof window or roof window. It has the outer frame and the casement frame as essential components.
  • the sash usually carries the glazing, which for example as single glazing or multiple glazing, especially double glazing or Triple glazing is present.
  • the glazing is framed, for example, by spars of the casement frame, with two vertical spars and two horizontal spars being provided in particular.
  • the window frame preferably also has two vertical bars and two horizontal bars. Two of the bars are connected to each other for both the casement and the window frame, in particular each of the vertical bars is connected to each of the horizontal bars and vice versa.
  • the roof window is intended and designed to be arranged on or in a roof of a building, in particular a residential building.
  • the roof is between an exterior environment and an interior space of the building, thus separating them from each other.
  • the roof essentially consists of a roof construction and a roof skin.
  • the roof structure has, for example, one or more rafters and one or more battens.
  • the roof battens can be divided into counter battens and support battens, with the presence of counter battens being purely optional.
  • the battens are usually arranged perpendicular to the rafters and attached to them.
  • the counter battens on the other hand, preferably run to the rafters.
  • the roof skin is arranged or fastened on the outside of the roof structure, thus delimiting the roof structure in the direction of the outside environment.
  • the roof skin is to be understood in particular as a roof covering or a roof seal.
  • the roof covering has, for example, a large number of tiles, roof tiles, shingles or the like.
  • the roof construction is preferably delimited by an inner wall.
  • the inner wall is arranged and/or fastened to the roof structure on its side facing the interior.
  • the roof window When the roof window is installed, it is inserted, for example, into a roof opening previously formed on the roof. After assembly, it is preferably supported on at least one of the rafters, for example on at least one of the battens.
  • the roof window is particularly preferably attached to the rafter and/or the roof batten after assembly, in particular by screwing.
  • the window frame is provided and designed for a stationary arrangement or fastening on the roof or in the roof opening of the roof.
  • the sash frame can be arranged stationary with respect to the window frame or be rigidly connected to the window frame.
  • the sash frame can preferably be displaced with respect to the blind frame, namely pivoted about at least one axis of rotation.
  • the casement can be pivoted about exactly one axis of rotation with respect to the window frame.
  • This axis of rotation is - in the installation situation of the roof window - on a top side of the casement or at least in an upper third of the casement.
  • a roof surface window can also be referred to as a hinged window.
  • the sash frame can be pivoted about a second axis of rotation with respect to the window frame, namely about a second axis of rotation that is different from the first axis of rotation.
  • the second axis of rotation is, for example, in a middle third of the casement. If the sash frame can be pivoted about both the first axis of rotation and the second axis of rotation, then the roof window is designed as a top-hung window.
  • the roof window is located between the interior and the outside environment, ie it separates them from one another at least temporarily. At least temporarily, however, it is desirable to ventilate the interior, ie to ventilate and/or vent. Ventilation means supplying air from the outside environment into the interior space, and venting means removing air from the interior space in the direction of the outside environment.
  • ventilation describes in general an exchange of air between the interior and the outside environment in any direction. If the casement can be pivoted with respect to the window frame, ventilation can be achieved by opening the roof window. However, it may be desirable to ventilate the room even when the roof window is closed, for example if the roof window cannot or should not be opened due to unfavorable ambient conditions or weather conditions.
  • the invention ventilates the interior at least temporarily via the flow path even when the skylight is closed.
  • a flow connection between the interior and the outside environment is thus established at least temporarily via the flow path, which runs through the roof surface window.
  • the flow path fluidly connects the first fluid port and the second fluid port, each formed on the skylight.
  • the first fluid opening is on the side of the flow path facing the interior and the second fluid opening is on the side of the flow path facing the outside environment.
  • the flow path preferably opens out via the first fluid opening into the interior space and the second fluid opening into the outside environment, in particular directly in each case.
  • An air conveying device for example a fan, is preferably present in the flow path. With the aid of the air conveying device, air can be conveyed in a targeted manner from the interior towards the outside environment or from the outside environment towards the interior. In this respect, the air conveying device enables forced ventilation of the interior. Of course, the air conveying device can also be omitted. In this case, the interior is ventilated via the flow path, in particular via natural convection.
  • provision can be made for the air to be guided over an outside of the glazing facing the outside environment when the interior is ventilated. Additionally or alternatively, the air can flow against or over a cover plate of the roof window. However, this can lead to condensation of water in the air, particularly at low outside temperatures, so that ice forms on the glazing and/or the cover plate, which is visually noticeable. In addition, condensate that occurs during ventilation can enter the interior.
  • the flow path runs at least in regions between the glazing and the spar of the casement. More precisely, the flow path runs between an inside of the glazing facing the interior and the spar, in particular a side of the spar facing the glazing. This creates the possibility of ventilating the interior in a visually particularly unobtrusive manner by means of the roof window, in particular when the roof window is closed.
  • a ventilation duct which runs between the glazing and the spar, in particular between the glazing and a support surface of the spar on which the glazing is supported at least in some areas, either directly or only indirectly via a support element.
  • the ventilation duct is therefore preferably delimited on the one hand by the glazing and on the other hand by the spar or a seal fastened to the spar.
  • the glazing is at least partially spaced from the spar of the casement, so that the air can flow between the glazing and the spar to ventilate the interior, namely even when the skylight is closed.
  • a further development of the invention provides that a seal is fastened to the sash frame, which is arranged between the spar and the glazing and rests on the frame when the skylight is closed, in particular a spar of the frame completely encroaches.
  • the seal rests on a side of the casement facing the glazing and largely or even completely overlaps the spar of the casement.
  • the first fluid opening is therefore preferably formed between the glazing and the seal and in this respect is delimited on the one hand by the glazing and on the other hand by the seal. In other words, seen in section, the first fluid opening extends from the seal to the casement.
  • the seal can be moved together with the sash frame.
  • the seal rests on the window frame when the skylight is closed.
  • the seal completely overlaps the space present between the casement and the frame, in particular an air gap present between the casement and the frame.
  • the seal preferably extends from a side of the spar of the casement that faces away from the spar of the frame to a side of the spar of the frame that faces away from the spar of the casement.
  • a further development of the invention provides that the flow path and/or the first fluid opening, viewed in section, is delimited on the one hand by the glazing and on the other hand by the spar and/or the seal. This has already been pointed out above.
  • the flow path or the first fluid opening therefore extend from the glazing to the spar or the seal.
  • the seal lies tightly against the casement. This ensures reliable protection of the casement against moisture and at the same time ensures ventilation of the interior via the flow path.
  • the seal also serves to reliably drain water that occurs along the flow path, namely in the direction of the outside environment.
  • the water is guided over the air gap present in the section between the casement and the window frame, so that the water cannot penetrate into it. Rather, the water is conducted across the air gap and can be discharged from there into the outside environment.
  • the seal protects the spar of the Seen frame completely overlaps in section, so that the water is carried away over the frame or the spar of the frame.
  • a development of the invention provides that a gap of constant size, representing the first fluid opening, is formed between the glazing on the one hand and the spar and/or the seal on the other hand.
  • the glazing is correspondingly arranged at a distance from the spar or the seal, so that the first fluid opening in the form of the gap is present between them.
  • the flow path particularly preferably opens directly into the interior via the first fluid opening, so that the first fluid opening is formed on the side of the casement or the spar of the casement facing the interior, at least seen in section. This achieves ventilation of the interior with a high degree of comfort, because the air flows into the interior along the glazing or flows out of the interior.
  • a further development of the invention provides that the window frame and/or the sash frame is overlapped at least in regions on an outside of the roof window, with the flow path being delimited at least in regions by the cover plate.
  • the cover plate can be rigidly connected to the frame or the casement. However, it can also be provided that there is a multi-part cover plate, with a first part of the cover plate being rigidly connected to the frame and a second part of the cover plate being rigidly connected to the casement frame and displaceable with respect to the other frame.
  • the cover plate preferably overlaps the window frame and the casement completely. Viewed in cross section, it extends from a side of the casement facing away from the frame to a side of the frame facing away from the casement. In particular, the cover plate overlaps the glazing in some areas, in particular an edge of the glazing.
  • the cover plate protects the window frame and/or the casement, preferably both, from the effects of the weather from the outside environment. In particular, the cover plate prevents water, in particular rainwater, from penetrating to the window frame or the casement. For this purpose, it is present on the outside of the roof window, ie on the side of the roof window facing the outside environment.
  • the cover plate is designed and arranged in such a way that it delimits the flow path at least in certain areas. This means that an air flow flowing along the flow path flows against or over the cover plate in some areas. For example, viewed in cross section, the flow path is delimited on the one hand by the cover plate and on the other hand by the blind frame and/or the casement frame and/or the glazing.
  • Such a configuration of the building closure element means that no further elements are required to form a flow channel that makes up at least part of the flow path, which enables a simple construction.
  • a development of the invention provides that the first fluid opening and the second fluid opening are fluidically connected to one another via an air space delimited by the cover plate.
  • the air space is delimited at least in regions by the cover plate, namely in the direction facing away from the window frame or in the direction facing the outside environment.
  • the air space is present between the cover plate on the one hand and the window frame and/or the casement frame on the other hand.
  • the second fluid opening is delimited by the cover plate, in particular additionally by the seal and/or a cover frame and/or a connecting element of the window frame acting sealingly on the cover frame.
  • the second fluid opening is present as a closed-edge opening in the cover plate. This means that the cover plate forms a continuous edge of the second fluid opening.
  • the second fluid opening is thus produced, for example, as a bore or the like in the cover plate.
  • the gasket, flashing, or connector may define the second fluid port.
  • the second fluid opening is present, for example, between the cover plate on the one hand and the seal, the covering frame or the connecting element on the other hand, ie it extends from the cover plate to this/this.
  • the flashing is an element that connects the roof window to the roof membrane.
  • the covering frame preferably extends, starting from the roof skin, up to the roof window, in particular up to below the cover plate when viewed in section.
  • the covering frame has a folded area or a folded edge, which protrudes in the direction facing away from the roof skin or the interior and correspondingly in the direction of the cover plate.
  • the cover plate preferably overlaps this fold, so that water running off the cover plate in the direction of the roof skin reaches the covering frame and is discharged via this from the roof surface window.
  • the connecting element preferably serves to connect the covering frame to the roof window or to the frame of the roof window.
  • the connecting element is preferably fastened to the window frame, in particular to the spar of the window frame, in particular detachably fastened without damage.
  • the connecting element preferably has a sealing leg which overlaps the fold on the side facing away from the spar of the window frame.
  • a development of the invention provides that the spar is a lower horizontal spar of the roof window.
  • the use of the lower horizontal spar as a spar has the advantage that any water accumulating along the flow path is discharged from the roof surface window by the influence of gravity, namely in particular via the seal. The water is thus forced on the seal by the influence of gravity in the direction of the second fluid opening and subsequently exits the roof window through the second fluid opening in the direction of the roof or the covering frame.
  • Such a design is again used to achieve a particularly high level of weather resistance.
  • a development of the invention provides a cross-section adjustment element for setting a flow cross-sectional area of the flow path, in particular the first fluid opening.
  • the cross-section adjustment element can be used to set the intensity with which the air is exchanged between the interior and the outside environment.
  • the flow cross-sectional area of the flow path is changed.
  • the flow path is completely interrupted in a first setting of the cross-section adjustment element and is at least partially or completely released in a second setting.
  • the cross-section adjustment element is particularly preferably present at the first fluid opening, so that it is used to adjust the flow cross-sectional area of the first fluid opening.
  • Such a design of the roof window enables the interior space to be ventilated as required.
  • the cross-section adjustment element is a slider, a rotary fastener or a zip fastener.
  • the slide means an element which is linearly displaceable to adjust the flow cross-sectional area.
  • the slide is in the form of a perforated plate or includes one.
  • the cross-section adjustment element can be in the form of a rotary lock, for example a flap or the like, which is mounted so that it can rotate about an axis of rotation.
  • the cross section adjustment element can be a zip fastener.
  • the zipper can be fully closed, partially open, or fully open in order to adjust the desired cross-sectional flow area in this way.
  • the configurations of the cross-section adjustment element described ensure excellent operability of the roof window.
  • the zip fastener can also be referred to as a zipper.
  • the zipper is preferably in the form of a toothless zipper.
  • the figure shows a schematic representation of an area of a roof window 1.
  • This has a window frame 2 and a casement 3 that can be displaced with respect to the window frame 2.
  • the casement frame 3 carries glazing 4 of the roof window 1.
  • the glazing 4 is in the form of multiple glazing in the exemplary embodiment illustrated here designed and has a first glass pane 5 and at least one second glass pane 6. Between the first glass pane 5 and the second glass pane 6, an air space 7 is formed.
  • the glass panes 5 and 6 are arranged at a distance from one another.
  • the second glass pane 6 extends further in the direction of the casement 3 than the first glass pane 5. Accordingly, viewed in section, the first glass pane 5 overlaps a spar 8 of the sash frame 3, but is arranged at a distance from a spar 9 of the window frame 2 .
  • the second glass pane 6, overlaps the spar 8 of the casement 3 completely and extends up to the spar 9 of the window frame 2, so it overlaps this at least partially, preferably mostly or completely or almost completely.
  • the seal 11 is on the casement 3 attached, for example by means of a connector 12. Seen in section, the seal 11 overlaps the spar 8 at least for the most part or even completely. For example, the seal 11 starts from an interior space 13 which is separated from an exterior environment 14 by means of the skylight 1 . Starting from the strut 8 of the casement 3, the seal 11 completely overlaps the air gap 10 when viewed in section. In addition, seen in section, the seal 11 overlaps the window frame 2 at least partially or even completely.
  • the seal 11 protrudes on the side facing away from the spar 8 over the spar 9 of the window frame 2, ie protrudes beyond it.
  • the seal 11 is supported on a connecting element 15 which is attached to the strut 9 of the window frame 2 and overlaps a flashing frame 16 .
  • the covering frame 16 preferably completely surrounds the roof window 1 and serves to connect the roof window 1 to a roof membrane of a roof on or in which the roof window 1 is arranged.
  • the seal 17 is attached to the spar 8 of the casement 3 and completely bridges the air gap 10 when the roof window 1 is closed, i.e. it rests on the spar 8 on the one hand and on the spar 9 on the other hand, preferably tightly.
  • the roof surface window 1 has a flow path 18 which opens into the interior 13 via a first fluid opening 19 on the one hand and into the outside environment 14 via a second fluid opening 20 on the other. Air can flow along the flow path 18, as indicated by the arrow 21 as an example.
  • the flow path 18 is at least partially between the glazing 4 and the casement 3 , in particular the spar 8 of the casement 3 .
  • the flow path 18 is between the glazing 4 and the seal 11, and is therefore delimited by it on opposite sides.
  • the flow path 18 is present between the first glass pane 5 and the spar 8 or the seal 11 and is delimited on opposite sides of them.
  • the first glass pane 5 is to be understood here as the side of the glazing 4 facing the sash frame 3 .
  • the glazing 4 is therefore arranged at a distance from the spar 8 or the seal 11 at least in regions, so that a gap 22 is formed.
  • the gap 22 opens into the interior space 13 via the first fluid opening 19 .
  • On its side facing away from the first fluid opening 19, the gap 22 opens into an air space 23, via which it is fluidically connected to the second fluid port 20.
  • the air space 23 is overlapped and/or delimited at least in regions by a cover plate 24 of the roof window 1 .
  • the cover plate 24 partially overlaps the glazing 4 seen in section and extends on its side facing away from the glazing 4 in section to beyond the strut 9 of the window frame 2, ie protrudes beyond it.
  • the cover plate 24 has a side wall 25 which runs towards the roof skin or the covering frame 16 and in the process passes the seal 11 .
  • the cover plate 24 thus overlaps the seal 11 laterally.
  • the second fluid opening 20 is delimited by the cover plate 24, in particular its side wall 25, and the seal 11 and/or the connecting element 15.
  • the roof window 1 has a cross-section adjustment element 26, by means of which a flow cross-sectional area of the flow path 18 can be adjusted.
  • the cross-section adjustment element 26 is assigned to the first fluid opening 19 so that a flow cross-sectional area of the first fluid opening 19 can be adjusted directly.
  • the cross-section adjustment element 26 is present here as a twist lock, in particular as a flap, which is rotatably mounted with respect to the casement 3 . Alternatively, however, it can also be designed as a slider or as a zip fastener.
  • the described configuration of the skylight 1 enables the interior 13 to be ventilated, in particular without the occurrence of ice formation at low temperatures in the outside environment 14. This is achieved by discharging the air according to the arrow 21 in the direction of the covering frame 16. In addition, air is routed in the interior 13 along the glazing 4, as a result of which a high level of comfort is achieved for a user of the interior 13, since drafts are effectively avoided.
