Method for modifying a housing for a ventilation device (1, 1', 1", 1"') and/or a screen device (1'") to form such a housing.

Description

The present invention relates to a housing for a ventilation device and/or a screen device, for installation in a window opening between an outside space and an inside space, wherein the housing:

comprises a base body for installation in the window opening; and
comprises a flange which projects with respect to the base body.

The present invention also relates to a method for modifying such a housing.
The invention is particularly suitable for use with ventilation devices and/or screen devices, a housing of which is fitted on top of, under or next to a window in the said window opening, typically on a window profile. Alternatively, these may optionally also be fitted to glazing to this end.
The term window opening is generally understood to mean an opening in a building skin, such as for example also a doorway. Such a building skin forms a screening between an outside space and an inside space, wherein the window opening is also situated between this outside space and this inside space.
In this case, the term screen is understood to refer to both a screen made of cloth and a screen made of roller shutter. The term screen device is then understood to mean both a roller cloth device and a roller shutter device.
The following description mainly concerns ventilation devices, without thereby limiting the invention to such ventilation devices.
Such housings are mainly used on the Dutch market, where intermediate window frames and windows with flange are used to ensure good water- and airtightness. In this case, the flange at least partly covers the intermediate window frames as a boundary of the window opening on the outer side, i.e. towards the outside space.
In order to allow the flange of the windows to also run on towards the intermediate window frames, where a ventilation device or a screen casing of a screen device is fitted above, below or next to such a window, it is known to then provide this ventilation device or this screen casing with a corresponding projecting flange.
Such ventilation devices are described and illustrated, for example, in NL 1 010 788 C , NL 1 029 154 C and NL 2 005 878 C . Providing a corresponding flange on the ventilation device also ensures good a good water- and airtightness around the ventilation device and benefits the appearance.
GB 2 351 753 A describes and illustrates a screen device which is provided with a similar flange.
Ideally, this projecting flange has the same height and width as the window frame, so that an uninterrupted stop is formed around the combination of the window frame and the ventilation device or screen casing which may screen off the intermediate window frame. Thus, the seal provided by the frame manufacturer may continue around the entire frame. However, a large number of window manufacturers use their own proprietary flange heights and flange widths. In addition, these window manufacturers also have their own types of seals, the dimensions of which vary greatly. The known solutions for housings with projecting flange are only suitable for a limited number of frame types at most. Different stops have to be provided in each case for the many other frame types. This is an inflexible and expensive solution.
It is the object of the invention to provide in such a housing which can be used for a large number of different frame types.
With ventilation devices which are provided to be fitted to glazing, such as for example described in EP 1 063 374 A2 , FR 2 517 354 A1 and BE 1 017 292 A3 , it is known to construct the ventilation device from several profiles which together also form a projecting flange which may be adaptable to the width of the glazing. In this case, there are solutions, on the one hand, where the width of the housing changes in a corresponding manner, as a result of which the functionality of the associated device changes, as in EP 1 063 384 A2 or in FR 2 517 354 A1 . With ventilation devices, the air flow passage of the different variants is in this case modified, resulting in different flow characteristics. On the other hand, there are solutions in this case which require different more expensive profiles in order to be able to modify the flange width without affecting the functionality of the device, such as for example with the solution from BE 1 017 292 A3 .
The object of the present invention therefore is to provide a less expensive solution in order to provide such a housing with the desired modularity without affecting the functionality of the ventilation device or the screen device.
This object of the invention is achieved by providing a housing for a ventilation device and/or a screen device, for installation in a window opening between an outside space and an inside space, wherein the housing comprises a base body for installation in the window opening and comprises a flange which projects with respect to the base body and which comprises a basic flange profile which projects with respect to the base body and comprises either an inner flange profile which is attachable to the basic flange profile to extend on the side of the basic flange profile facing the inside space or comprises a outer flange profile which is attachable to the basic flange profile to extend on the side of the basic flange profile facing the outside space. The flange may also comprise both such an inner flange profile and such an outer flange profile. According to the invention, the flange is in each case only connected to the base body by its basic flange profile. The optional inner flange profile and/or the optional outer flange profile are only connected to the base body via the basic flange profile, but not directly.
In a first variant, such a housing may be used without an inner flange profile or outer flange profile, in which case only the basic flange profile forms a relatively narrow projecting flange.
In a second variant, an inner flange profile may be attached to the basic flange profile, in which case this inner flange profile, together with the basic flange profile, forms a relatively wide composite projecting flange, with the basic flange profile forming the first flange part and the inner flange profile the second flange part. In this way, the composite projecting flange is now of a modular construction. Analogously, in a third variant, an outer flange profile may be attached to the basic flange profile in order to form a relatively wide composite projecting flange.
In a fourth variant, both a said inner flange profile and a said outer flange profile may be attached to the basic flange profile in order to form a relatively wide composite projecting flange.
By means of such an inner flange profile and/or such an outer flange profile, it is easily possible to change the flange width.
By optionally attaching the inner flange profile to the basic flange profile in embodiments with a basic flange profile and an inner flange profile, two different possible flange widths are already provided.
It is also possible to obtain two different possible flange widths in this way with embodiments with a basic flange profile and an outer flange profile.
With embodiments with both an inner flange profile and an outer flange profile, it is possible to obtain four different possible flange widths in this way.
In a preferred embodiment, the flange of a housing according to the present invention comprises a set of at least two said inner flange profiles which are each separately, exchangeably attachable to the basic flange profile. Alternatively or additionally, the flange may comprise a set of two of said outer flange profiles which are each separately, exchangeably attachable to the basic flange profile. By providing different mutually exchangeable inner flange profiles and/or outer flange profiles with different widths (and/or with different heights), it is possible to accommodate a large number of possible composite flange widths (and/or flange heights).
The flange preferably also comprises a set of at least two said basic flange profiles which are each separately, exchangeably accommodable in the housing. By, in addition, providing different variants of basic flange profiles with, for example, different heights (and/or with different widths), it is possible to obtain a large range of possible composite flange widths and flange heights. As a result thereof, the housings can be used with virtually all commercially available frame systems.
Preferably, the embodiments of a housing according to the present invention with inner flange profile also comprise a filler piece which is attachable to the basic flange profile and to which the inner flange profile is attachable in order to attach this inner flange profile to the basic flange profile. The embodiments of a housing according to the present invention with outer flange profile preferably also comprise a filler piece which is attachable to the basic flange profile and to which the outer flange profile is attachable in order to attach this outer flange profile to the basic flange profile.
Below, the filler piece in inner flange profiles is discussed further and specific embodiments of this filler piece and the basic flange profile connectable thereto and the inner flange profile connectable thereto are discussed. The remarks about filler pieces hold true, mutatis mutandis, for outer flange profiles.
By means of this additional filler piece, it is possible to achieve an even greater variation of flange heights and flange widths, using a limited number of basic flange profiles, a limited number of inner flange profiles and a limited number of such filler pieces. This filler piece forms an additional modular part of the modular composite projecting flange.
Preferably, this filler piece is provided in the form of a filler profile which preferably extends along the length of the basic flange profile. Alternatively, different filler pieces may also be provided, distributed along the length of the basic flange profile. This filler profile then forms, together with the basic flange profile and the inner flange profile, a composite projecting flange, with the basic flange profile as first modular flange part, the inner flange profile as second modular flange part and the filler profile as third modular flange part.
This filler profile preferably only extends between the basic flange profile and the inner flange profile.
In a particularly preferred embodiment, the filler piece is at least partly elastic. This facilitates assembly of the combined projecting flange. In addition, an at least partly elastic filler piece can seal the seam between the projecting flange and the inner flange profile. To this end, this filler piece may be provided, for example, with an incorporated elastic seal for sealing this seam.
This filler piece is preferably entirely elastic and made, for example, of rubber.
A said filler piece of a housing according to the present invention is furthermore preferably attachable to this housing by means of a click-fit connection.
If this filler piece is elastic, it is fairly simple to also provide it with elastic click-fit means in order to produce this click-fit connection.
The inner flange profile of a housing according to the present invention is preferably also attachable in this housing by means of a click-fit connection, so that this can easily be accommodated in this housing.
Still more preferably, with a housing according to the present invention, a said filler piece is click-fittable to the basic flange profile and the inner flange profile is click-fittable to the filler piece.
In a particularly stable variant, the basic flange profile comprises three fitting slots extending above one another, the filler piece comprises three fitting legs which extend above one another and are fittable into the fitting slots of the basic flange profile, the inner flange profile comprises three fitting slots extending above one another and the filler piece comprises three fitting legs which extend above one another and are fittable into the fitting slots of the inner flange profile.
In this case, the respective slots and legs are preferably arranged above one another, viewed in a direction in which the basic flange profile is upright with respect to the base body of the housing (height direction of the flange).
In this case, at least one said fitting leg of the filler piece may then, more specifically, be designed as a click-fit leg which is click-fittable into the corresponding fitting slot of the basic flange profile in order to click-fit the filler piece to the basic flange profile and at least one said fitting leg of the filler piece may, more specifically, be designed as a click-fit leg which is click-fittable into the corresponding fitting slot of the inner flange profile in order to click-fit the filler piece to the inner flange profile.
Preferably, in each case at least the top or at least the bottom fitting leg is provided as said click-fit leg. When the top or the bottom fitting leg is provided as the click-fit leg, then the bottom or the top fitting leg, respectively, may be designed as a hook-shaped leg which may be hooked into the corresponding fitting slot.
The inner flange profile of a housing according to the present invention is preferably at least partly rigid. To this end, this may be made, for example, from aluminium or it could be made from plastic, such as for example from PVC.
The outer flange profile is preferably at least partly rigid as well.
Preferably, the inner flange profile furthermore extends only between the basic flange profile and a boundary of the window opening which delimits the window opening on all sides.
The inner flange profile preferably extends along the entire length of the basic flange profile.
The housing furthermore preferably comprises a seal which is coupleable to the inner flange profile in order to extend, on the side of the inside space of the inner flange profile, between the inner flange profile and a boundary of the window opening which delimits the window opening on all sides. By means of this seal, a certain tolerance for the flange widths can be compensated for, so that the range of possible combinations of flange widths is increased even further.
To this end, the inner flange profile may preferably comprise an attachment slot for attaching the seal thereto. By means of such an attachment slot, it is relatively easy to accommodate the seal of the manufacturer of the window frame onto which the housing adjoins or an identical seal in this attachment slot and thus allow the seal to run on over the entire frame.
More specifically, the flange will be configured such that, in the fitted position, at the location of a boundary which delimits the window opening on all sides, it extends at least partly next to the window opening and next to the boundary. This is the case when intermediate window frames or curtain walls are used. In this case, the flange will screen off this boundary towards the outside space. With curtain walls, the flange is additionally clamped with a clamping profile.
The basic flange profile of a housing according to the present invention may, more specifically, be configured as a first profile part of a housing profile, of which a second profile part forms part of the base body. By enabling the basic flange profile to form part of such a housing profile, a simple connection between the projecting flange and the base body is achieved.
Preferably, the base body of a housing according to the present invention is configured to be attached to a window profile. In this way, the housing is particularly suitable for applications with intermediate window frames or curtain walls.
The object of the present invention is also achieved by providing a ventilation device which comprises an abovementioned housing according to the present invention. Such a ventilation device comprises an air flow passage which allows through-flow for the supply of air from the outside space to the inside space.
In a preferred embodiment of such a ventilation device, the basic flange profile forms part of a cover profile of the housing, which is provided with a rain cover for protecting the air flow passage of this ventilation device against precipitation. This cover profile then forms an abovementioned housing profile with the basic flange profile as first profile part and the rain cover as second profile part.
The object of the present invention is additionally also achieved by providing a screen device which comprises an abovementioned housing according to the present invention.
The object of the present invention is furthermore also achieved by providing an assembly of a window profile and a housing for a ventilation device and/or a screen device, in which the base body is fitted on the window profile and in which the flange projects with respect to the base body on the side of the base body opposite the side with which the base body is fitted on the window profile.
Lastly, the object of the present invention is also achieved by providing a method for modifying a housing for a ventilation device and/or a screen device, comprising a base body for installation in a window opening, wherein this housing has been provided or is provided with an existing flange which projects with respect to the base body, and is provided with:

an inner flange profile which is attached to the existing projecting flange in order to extend towards the inside space on the side of the existing projecting flange,
and/or an outer flange profile which is attached to the existing projecting flange in order to extend towards the outside space on the side of the existing projecting flange;

Preferably, in this case, the inner flange profile is attached to the original projecting flange by means of a said filler piece and/or the outer flange profile is in this case attached to the original projecting flange by means of a said filler piece in order to form the new projecting flange.
The present invention will now be explained in more detail by means of the following detailed description of a few preferred housings for a ventilation device and a combined ventilation device and screen device according to the present invention and this ventilation device and combined ventilation device and screen device. The sole aim of this description is to give illustrative examples and to indicate further advantages and features of the present invention, and may therefore not be interpreted as a limitation of the area of application of the invention or of the patent rights defined in the claims.

The air vents (1) shown in Figs. 1, 3 and 13 are configured for installation in a window opening (46) above a window (53, 55, 58, 54, 56), that is on the window profile (53, 55). The screen casing of the combined ventilation device and screen device (1') shown in Fig. 14 is configured for installation in a window opening (46) above a window (63, 58), that is on the window profile (63). Alternative embodiments may also be configured for installation under a window or for installation next to a longitudinal side of a window.
As will be described below, the illustrated air vents (1) and the illustrated screen casing are provided with a composite upright flange (50, 50', 50", 50"', 50"") according to the invention in order to cover a boundary (47) of the window opening (46) in which the air vent (1) or the screen casing is fitted.
The air vent (1) illustrated in Fig. 3 comprises a housing which comprises a base body (51) and a flange (50) which is upright with respect to the base body (51). The base body (51) is provided in a known manner with an outer profile (26) which is arranged in the outside space (48) and a bottom profile (27) and a top profile (25). This outer profile (26), this bottom profile (27) and this top profile (25) are elongate profiles which extend over the entire length of the top side of the window.
In addition, the base body (51) also comprises head plates which close off the base body (51) at the ends. Furthermore, the base body (51) is now provided with a rain cover (22) which is arranged in the outside space (48).
On the inner side, the air vent (1) is provided with a vent profile (29) which is click-fitted onto the top profile (25) and the bottom profile (27) and provides a finish for the air vent (1) towards the inside space (49).
Above this vent profile (29), a finishing profile (57) is provided which is attached to the top profile (25).
At the bottom of the air vent (1), known filler pieces (34, 35, 36) are provided to secure the air vent (1) above the window profile (53).
Of course, variants of the listed profiles of the air vent (1) are also possible, in which case the number of these profiles may also vary.
The air vent (1) is provided with an air flow passage (20) which extends between the bottom profile (27) and the cover profile (21) and the top profile (25). Air can flow from an inlet (23) of the air vent (1) to an outlet (24) of the air vent (1) via this air flow passage (20). Here, the inlet (23) is arranged at the outside space (48) and the outlet (24) at the inside space (49), so that outside air can be supplied from the outside space (48) to the inside space (49). The outer profile (26) and the vent (29) are provided with passage openings through which this outside air can flow when flowing from the inlet (23) to the outlet (24) through the air flow passage (20). The bottom profile (27) and the top profile (25) are mutually connected and provided with die holes in order to permit the air to flow through both.
In the air flow passage (20), a self-regulating flap (31) is arranged for regulating the flow rate of the supplied outside air. On the inner side of the air vent (1), a closing flap (30) is hingeably attached to the vent profile (29), by means of which the air flow passage (20) can be closed off.
Of course, other means for regulating the air flow than this self-regulating flap (31) and this closing flap (30) are possible.
The components of the air vent (1) mentioned above may be made from plastic and/or from aluminium, for example via extrusion.
The air flow passage (20) is furthermore provided with acoustic insulation (33). In alternative embodiments, this insulating material (33) may be omitted or the air vent (1) may be provided with other means for attenuating sound.
The housing comprises a cover profile (21) which is attached to the outer profile (26) by means of a spacer (32). To this end, this spacer (32) is screwed to the outer profile (26). The cover profile (21) is then click-fitted to the outer profile (26) and this spacer (32).
The bottom part of the cover profile (21) forms the rain cover (22) of the base body (51) which protects the air flow passage (20) against precipitation.
The top part of the cover profile (21) consists of a basic flange profile (2) which is upright with respect to the base body (51) of the housing.
A filler profile (4) is click-fitted onto the basic flange profile (2). An inner flange profile (3) is in turn click-fitted onto the filler profile (4). Together, the basic flange profile (2), this filler profile (4) and this inner flange profile (3) form a composite upright flange (50). In the fitted position, the inner flange profile (3) extends completely between the basic flange profile (2) and the boundary (47) of the window opening which is covered by the composite upright flange (50).
In order to bring about the click-fit connection between the basic flange profile (2) and the filler profile (4), on the one hand, and between the filler profile (4) and the inner flange profile (3), on the other hand, the filler profile (4) is elastic and provided with elastic click-fit legs (10, 16). This filler profile (4) may to this end be made from, for example, rubber.
In addition to the click-fit legs (10, 16), the filler profile (4) is provided with hook legs (8, 14) which can be hooked into corresponding fitting recesses (5, 11) of the basic flange profile (2) and the inner flange profile (3), respectively.
The basic flange profile (2) is provided with a fitting recess (7) which corresponds to a click-fit leg (10) of the filler profile (4) and into which this click-fit leg (10) is click-fittable after the respective hook leg (8) of the filler profile (4) has been hooked into the corresponding fitting recess (5). The inner flange profile (3) is analogously provided with a fitting recess (13) which corresponds to a click-fit leg (16) of the filler profile (4) and into which this click-fit leg (16) is click-fittable after the respective hook leg (14) of the filler profile (4) has been hooked into the corresponding fitting recess (11).
Between the hook leg (8) and the click-fit leg (10), towards the basic flange profile (2), the filler profile (4) is furthermore provided with a stabilizing leg (9) which is fittable in a corresponding fitting recess (6) of the basic flange profile (2) in order to produce a stable assembly. Analogously, between the hook leg (14) and the click-fit leg (16), towards the inner flange profile (3), the filler profile (4) is provided with a stabilizing leg (15) which is fittable in a corresponding fitting recess (12) of the inner flange profile (3) in order to produce a stable assembly.
The filler profile (4) is furthermore provided with a marker leg (17) which is turned towards the inner flange profile (3) in order to orient the filler profile (4) correctly with respect to the basic flange profile (2) and the inner flange profile (3).
The inner flange profile (3) is rigid and may be made from aluminium or from plastic, for example via extrusion. On the side facing away from the filler profile (4), the inner flange profile (3) is provided with an attachment slot (19) for attaching a seal (52), as is illustrated in Fig. 1. This seal (52) may typically be the same seal as the seal which is provided by the window manufacturer for the window (53, 58, 54) to which the air vent (1) is attached.
In order to vary the height and the width of the composite upright flange (50), the cover profile (21), the filler profile (4) and the inner flange profile (3) may be exchanged for variants thereof, as is illustrated in Figs. 2 to 10.
The cover profile (21) of the air vent (1) which is provided with the basic flange profile (2), which was illustrated separately in Fig. 4, may thus be exchanged, for example, for an alternative cover profile (21'), whose basic flange profile (2') is higher, as is illustrated in Fig. 5, than the basic flange profile (2) from Figs. 3 and 4. In this way, it is possible to vary the height of the composite upright flange (50). The filler profile (4), which was illustrated separately in Fig. 6, may be exchanged, for example, for an alternative filler profile (4'), as illustrated in Fig. 7, which is wider. In this way, it is possible to vary the width of the composite upright flange (50). This relatively wide filler profile (4') is provided with an incorporated seal (18) at the top in order to seal the opening which was thus created between the basic flange profile (2) and the inner flange profile (3), as can be seen in Fig. 11.
The inner flange profile (3), which was illustrated separately in Fig. 8, may be exchanged, for example, for an alternative inner flange profile (3', 3"), as illustrated in Fig. 9 or 10, which is wider. In this way, it is also possible to vary the width of the composite upright flange (50). These alternative inner flange profiles (3', 3") may also be provided with different attachment slots (19), as can be seen in Figs. 8 to 10, in which alternative embodiments of seals (52) can be attached.
If the filler profile (4, 4') and the inner flange profile (3, 3', 3") are omitted, only the basic flange profile (2, 2') may serve as the upright flange (2, 2'). The top fitting slot (5, 5') of the basic flange profile (2, 2') may then serve as an attachment slot for attaching a seal (52), which may be chosen to be the seal of the window manufacturer. To this end, the alternative basic flange profiles (2, 2') may be provided with different top fitting slots (5, 5'), as can be seen in Figs. 4 and 5, in which alternative embodiments of seals (52) may be attached.
In Fig. 11, the alternative filler profile (4') from Fig. 7 and the alternative inner flange profile (3') from Fig. 9 are attached to the basic flange profile (2) of the cover profile (21) from Fig. 3.
In Fig. 10, the alternative cover profile (21') is provided with the alternative basic flange profile (2') from Fig. 5, to which the alternative filler profile (4') from Fig. 7 is attached and the alternative inner flange profile (3") from Fig. 10.
The elongate housing of the air vent (1) preferably extends along the entire length of the top side of the window to which it is attached. The head plates are then preferably provided with a composite upright flange in an analogous way.
Existing air vents may easily be converted into air vents (1) according to the present invention, for example by screwing a spacer (32) onto the outer profile (26) thereof, by click-fitting a cover profile (21, 21') thereon and by optionally fixing a filler profile (4, 4') and an inner flange profile (3, 3', 3") to the basic flange profile (2, 2') of this cover profile (21, 21').
In cases where an existing air vent is already provided with an upright flange, a filler profile (4, 4') and an inner flange profile (3, 3', 3") may, for example, be fixed to this upright flange in order to transform these into an air vent (1) according to the present invention.
Fig. 2 shows the window opening (46) with its boundary (47), in which the air vent from Fig. 1 is fitted. In Fig. 1, glazing (58) is fitted in this window opening (46) which is set in window profiles (53, 54). The air vent is installed between the top window profile (53) and the boundary (47) of the window opening (46), so that its base body (51) is installed in the window opening (46) and the upright flange (50) extends next to the window opening (46) and next to the boundary (47) in order to partly cover the boundary (47) towards the outside space (48).
The base body (51) of the air vent illustrated in Fig. 1 is identical to the base body (51) of the air vent (1) illustrated in Fig. 3. The flange (50') which is upright with respect to this base body (51) now comprises:

the basic flange profile (2') from Fig. 5;
the filler profile (4) from Fig. 7; and
the inner profile (3) from Fig. 8.

The air vent (1") illustrated in Fig. 13 is fitted in a curtain wall. The base body (51) of this air vent (1) is identical to the base body (51) of the air vents (1, 1') illustrated in Fig. 1 and 3. The flange (50"") which is upright with respect to this base body (51) now comprises:

an alternative basic flange profile (2"), the position of which is largely offset with respect to the base body (51) compared to the above-described basic flange profiles (2, 2');
a first filler profile (4") which is even wider than the filler profiles (4, 4') from Figs. 6 and 7 and is attached to the basic flange profile (2");
a rigid intermediate flange profile (60) which is attached to the first filler profile (4");
a second filler profile (4") which in this case is an identical filler profile (4") to the first filler profile (4") and is attached to the intermediate flange profile (60);
the inner flange profile (3') from Fig. 9 which is attached to the second filler profile (4"); and
a cover profile (62) which is attached to the inner flange profile (3').

Like the bottom window profile (56) of the window (55, 58, 59) in this curtain wall which is clamped against the boundary (47) by means of a clamping profile (59), this composite flange (50"") is also clamped against the boundary (47) by means of a clamping profile (59), on one side with a seal (61) between the basic flange profile (2') and the clamping profile (59) and on the other side with a seal (52) between the cover profile (62) and the boundary (47).
The housing of the combined ventilation device and screen device (1') illustrated in Fig. 14 comprises, in a known manner, a top profile (25'), an outer profile (26'), a bottom profile (27') and an inner profile (28'). On the inner side of the combined ventilation device and screen device (1'), an intermediate profile (37) and a vent profile (29') are provided which are closable by means of a closing flap (30'). At the bottom, a further intermediate profile (38) is provided. These profiles (25', 26', 27', 28', 29', 30', 37, 38) are elongate profiles which extend along the entire length of the top side of the window (63, 58). In addition, the housing also comprises head plates which close off the housing at the ends.
The top profile (25') is provided, in a known manner, with an attachment slot (39) for attachment of this top profile (25') by means of, for example, a dowel, to the top side of the window opening (46). The housing may furthermore be fixed further in the window opening (46) in a known manner by means of screws.
The bottom profile (27') is provided in a known manner for attachment above a window profile (63).
Between the head plates, a screen roller (40) is arranged so as to be rotatable about its axis. This screen roller (40) extends in a space between the top profile (25') and the bottom profile (27'). To this screen roller (40), a cloth (41) is attached which can be rolled up onto and unrolled from this screen roller (40) like a screen (41) in order to at least partly screen off the window opening (46) against, for example, sunlight and/or insects and/or heat and/or cold.
The lateral sides of the screen (41) and/or the bottom slat (42) attached thereto may be guided in a screen guide and/or a slat guide (43) which is arranged at the location of the lateral sides of the window opening.
Next to the screen roller (40), an upright wall (44, 45) also extends between the top profile (25') and the bottom profile (27'). The upright wall (44, 45) is configured to be arranged in a zone above the frame, inside the width of the frame, in order to absorb the loads on the frame. The top part of this upright wall (44, 45) is configured as an air vent (44).
The said profiles (25', 26', 27', 28', 29', 30', 37, 38) and upright wall (40, 41) of the combined ventilation device and screen device (1') may be made from plastic and/or aluminium in a known manner.
The combined ventilation device and screen device (1') is provided with an air flow passage (20') through which air can flow from an outside space (48), via an inlet (23'), over the screen roller (40) and through air passage openings in the air vent (44) to an outlet (24') at an inside space (49) and through the vent (29') installed there.
Here again, a self-regulating flap (31') is arranged in the air flow passage (20') for regulating the flow rate of supplied outside air. On the inner side, the said closing flap (30') is hingeably attached, so that the air flow passage (20') is closable thereby. Here as well, other means are obviously also possible for regulating the air flow.
Next to the air flow passage (20'), insulation (33') is arranged again.
Here, the basic flange profile (2"') is provided on the top profile (25'). A filler profile (4), such as illustrated separately in Fig. 6, is click-fitted onto the basic flange profile (2'"). An inner flange profile (3) is in turn click-fitted onto the filler profile (4), as is illustrated separately in Fig. 8. Together, the basic flange profile (2'"), this filler profile (4) and this inner flange profile (3) form a composite upright flange, of which the filler profile (4) and the inner flange profile (3) are exchangeable with variants thereof, as described above with the air vent (1) illustrated in Fig. 3.
