Description

The invention relates to a roof window with a frame and with respect to the frame movable, a glazing-bearing sash, wherein the frame has at least one Blendrahmenholm on which a along the frame frame extending cover plate is secured by a fastening device.

The roof window is intended for installation in a building, in particular in a roof of the building. The skylight has the frame, which is finally fixed stationary with respect to the building, and the sash. The casement is displaceable with respect to the frame, in particular rotatable about a rotation axis. For this purpose, the casement is preferably mounted on the frame. The sash frame carries the glazing of the skylight. The glazing can be designed as single glazing or as multiple glazing, in particular double glazing, triple glazing or quadruple glazing. The glazing is enclosed, for example, by wing frame members of the sash, in particular two vertical beams and two horizontal beams are provided. The frame also preferably has two vertical bars and two horizontal bars. The initially described frame frame spar is present as one of these spars. In each case two of the spars, so the sash or the Blendrahmenholme are connected to each other, in particular, each of the vertical beams is connected to each of the horizontal bars.

Along the frame spar extends the cover plate. Preferably, the cover plate is arranged parallel to a longitudinal center axis of the frame spar and overlaps the frame spar in the direction of its longitudinal central axis at least partially, but preferably completely. The cover plate can be designed in one piece or in several parts. It is preferably made of the same material, so it consists of the same material throughout. For example, a sheet metal is used as the material for the cover plate.

The frame spar in the context of this description is preferably in the form of a vertical spar whose longitudinal central axis is at least approximately parallel to a roof skin of the roof, in which the roof window is arranged, runs. The cover plate is fastened by means of the fastening device on the frame spar. For example, the fastening device is used to produce a form-fitting, in particular detachable connection between the cover plate and the frame spar. In the latter case, a damage-free disassembly of the cover plate of the frame spar is possible, for example in the course of an exchange of the cover plate.

EP 2 947 227 discloses a roof window according to the preamble of the first claim.

It is an object of the invention to provide a roof window, which has advantages over the known roof windows, in particular allows easier and faster installation.
This is achieved according to the invention with a roof window with the feature of claim 1. In this case, it is provided that on the fastening device over a base body of the holding member in the direction away from the frame frame spar protruding Positioniervorsprung for positioning of the sash with respect to the frame in a closing of the roof window is formed by cooperation with a present on the sash positioning.
The fastening device thus serves on the one hand the reliable holding of the cover plate on the frame spar and in addition the positioning of the sash. To make the installation of the roof window as simple as possible, the fastening device is designed in several parts and has at least the holding part and the cover. The holding part is attached to the frame spar, for example by means of at least one screw, so exactly one screw or more screws. Additionally or alternatively, a cohesive fastening of the holding part may be provided on the frame spar, for example by gluing or the like. About the holding part of the cover engages the frame spar. Particularly preferably, the cover is fastened exclusively via the holding part on the frame spar. This means that while the cover member may abut the frame spar, in particular away from the holding member, the actual attachment of the cover member with respect to the frame spar is, however, exclusively on the holding part.

The connection between the cover part and the holding part is form-fitting and is produced by means of the form-fit fastening device. The cover is in this respect using the form-fitting fastening device to the holding part and this finally attached to the frame spar. The form-fitting connection produced by means of the positive-locking fastening device between the holding part and the cover part is preferably releasable, so that the cover part can be removed without damage from the holding part, for example in the context of the above-described replacement of the cover plate.

It has already been mentioned above that with the aid of the fastening device not only the attachment of the cover plate to the window frame spar is to take place, but that additionally the positioning of the wing frame with respect to the window frame is provided. The sash frame is rotatably supported about at least one axis of rotation with respect to the frame, in particular rotatably mounted on the frame. Due to play in the storage and / or slight deformations of the sash and / or the frame may come with the roof window open to an off-center arrangement of the sash with respect to the frame. This means that the air gap present between the window frame and the casement can be different in size on opposite sides of the roof window.

In order to position the casement with respect to the frame during the closing of the roof window such that the skylight can be completely closed and / or locked after closing with little effort, the positioning projection and the positioning device are provided. In the context of positioning is preferably carried out a centering of the sash with respect to the frame, in particular in the lateral direction, so that subsequently the vertical beams of the frame from the respective nearest vertical spar of the sash have the same or at least approximately the same distance.

The Positioniervorsprung so far represents a guide device for the sash, which during the closing of the roof window with the sash, in particular the positioning of the sash, comes into abutting contact to align or position the sash with respect to the frame. For this purpose, the positioning projection and / or the positioning device are preferably arranged on the side of the window frame or of the sash frame facing away from the axis of rotation of the sash frame with respect to the window frame.

Particularly preferably, the roof window has a plurality of positioning protrusions and a plurality of positioning devices, which are present on opposite sides of the roof window, that is, on spaced-apart vertical beams of the roof window. For example, a plurality of frame spars are provided with one of a plurality of the fastening devices described, wherein a positioning projection of the type described is formed on each of the fastening devices. In other words, in this respect a plurality of frame beams each have a fastening device assigned according to this description or attached to it. The positioning projections present on the fastening devices preferably project respectively in the direction of the respective other of the fastening devices, so that the positioning projections project toward one another.

Similarly, the sash has several positioning means which are arranged on opposite sides of the sash. For example, the positioning means are each associated with wing frame spars, which are present as vertical beams. The positioning devices are preferably arranged on opposite sides of the wing frame spars, ie, they face away from each other. If the positioning device comes into abutting contact with the corresponding positioning projection during the closing of the roof window, this leads to a displacement of the sash frame in the lateral direction towards the respective other positioning projection. In that regard, each of the positioning projections and the respective positioning device are designed to urge the sash frame in the lateral direction in the direction of the other of the positioning projections, provided that the positioning device comes into abutting contact with the positioning projection. When the roof window is closed, both positioning devices are preferably located on the respective positioning projection, so that the sash frame is fixed and in particular centered with respect to the window frame.

The integration of the positioning projection in the positioning of the cover plate allows easy and quick installation of the roof window. In particular, only the holding part has to be fastened to the frame spar, for example by means of the at least one screw. Subsequently, the cover plate is arranged with the cover on the holding part. Subsequently, both the cover plate is held on the frame spar and the positioning projection formed on the frame spar.

A further embodiment of the invention provides that the holding part on an upper side surface of the frame spar and on one of a Blendrahmenholmkante to the top surface adjacent inner side surface of the frame spar the Blendrahmenholmkante abuttingly abuts. The frame spar is limited in total by a plurality of surfaces, namely the top surface, a bottom surface, the inside surface and an outside surface. The top surface is in the direction of an outside environment on the roof window, while the bottom surface is disposed on the side facing the building of the roof window and so far away from the outside environment. The top surface and the bottom surface face each other on the frame spar. The top surface and the bottom surface are connected to each other by the inner side surface and the outer side surface, respectively. In other words, the inner side surface adjoins, on the one hand, the upper side surface and, on the other hand, the lower side surface, while the same applies to the outer side surface. The inner side surface of the frame spar is facing the glazing, while the outer side surface faces away from the glazing.

In other words, the inner side surface of the frame spar facing an opposite, preferably parallel to the frame frame spar extending other frame frame spar, while the outer side surface facing away from this other frame frame spar. The upper side surface and the inner side surface of the frame spar now merge into one another at a frame edge of the frame, wherein the frame frame spar edge preferably runs parallel to a longitudinal center axis of the frame frame member. The Blendrahmenholmkante can be seen in cross section square or rounded. The holding part engages around the frame beam side edge in such a way that it bears against both the top side surface and the inside surface of the frame spar. It relies in this respect on the top surface and on the inside surface.

A further embodiment of the invention provides that the holding part has a contact area resting on the upper side surface, in particular flat, and a contact region bearing against the inner side surface, in particular flat. This has already been pointed out above. Hereinafter, the area of the holding part assigned to the top surface area is referred to as the rest area and the area assigned to the inside area is referred to as the rest area. The flat object is preferably understood to mean the object in the region of a two-dimensional surface, ie not merely the presence of a point contact or line contact. Of course, the abutment can alternatively be present only in accordance with the point contact at a point or according to the line contact along a line.

A preferred embodiment of the invention provides that the cover part has a cover frame side facing away from the cover part surface, which is aligned with the cover part fixed to the cover part with a the frame frame member facing away from the support area side surface of the contact area, the cover part side surface and the abutment area side surface are arranged on opposite sides of the positioning, in particular directly adjacent to these. After the mounting of the cover on the holding part are so far the Blendrahmenholm facing away surfaces of the cover and the holding part, namely the Abdeckteilseitenfläche and the contact area side surface, in an imaginary plane and aligned with each other. The positioning projection protrudes in the direction away from the frame spar rail both beyond the cover part side surface and beyond the contact area side surface. With such a configuration, an excellent visual impression of the roof window is achieved. The cover member side surface and the abutment region side surface are disposed on opposite sides of the positioning projection, thus sandwiching it between them. Particularly preferably, the cover part side surface and the abutment region side surface each run up to the positioning projection, ie they directly adjoin the positioning projection.

A further embodiment of the invention provides that the positioning projection forms an end stop for the cover with respect to the holding part. During assembly of the cover part on the holding part, the cover part is preferably pushed onto the holding part, so that subsequently the holding part engages in the cover part. The positioning projection serves as an end stop for the cover with respect to the holding part. Preferably, the positioning projection is arranged such that when reaching a mounting position of the cover with respect to the holding part, in which the cover is subsequently held by the form-fitting fastening means on the holding part, the cover rests against the positioning projection. Preferably, in such a use of the positioning projection as an end stop of the positioning projection is formed exclusively on the holding part.

In the context of a further embodiment of the invention, it is provided that the cover part rests with a lower edge on an upper side surface of a further frame frame spar, wherein the lower edge of the cover part is aligned with a lower edge of the contact area delimiting the contact area side surface. The further frame spar is preferably connected to the frame spar, in particular attached to this. The further frame spar is preferably angled with respect to the frame spar, so that a longitudinal center axis of the further frame frame spar with the longitudinal center axis of the frame spar at an angle which is greater than 0 ° and less than 180 °. Preferably, the angle is 90 ° or about 90 °, so that therefore the further frame spar is arranged perpendicular or at least substantially perpendicular to the frame spar. The further frame spar has the top surface and the outside surface, reference being made to the embodiments for the frame spar with regard to the definition of these surfaces. The upper side surface and the outer side surface adjoin one another on the frame side rail edge.

The cover now has, for example, a covering tongue, which covers the outer side surface of the further frame frame spar at least partially, but preferably completely. In the latter case, the covering tongue extends beyond the frame spar rail edge between the top side surface of the outside surface and up to a further frame frame spar bordering the further frame spar or its outside surface in the direction of the roof. The further frame spar is preferably to be interpreted widely within the scope of this description. Thus, not only a part of the frame can be regarded as a further frame frame spar, but for example also additional attachments, which are arranged and / or attached to this spar. Preferably, the further frame spar also comprises a retaining rail for a cover frame of the roof window, which is fastened to the frame.

A further development of the invention provides that the abutment region adjoins a positioning web of the positioning protrusion, wherein the abutment region has smaller dimensions in the direction away from the frame spar than the positioning protrusion. The positioning projection thus has at least the positioning web, which adjoins the contact region, in particular protrudes beyond the cover part side surface present on the abutment region in the direction away from the frame member spar. The contact area now has smaller dimensions in the direction away from the frame spar than the positioning projection. In other words, the material thickness of the contact area is less than that of the positioning projection, so that the positioning projection protrudes beyond the contact area. In this case, both the contact area and the positioning projection respectively depart from the frame spar, so they rest against it.

A further embodiment of the invention provides that the positioning projection has an entry web adjoining the positioning web, which adjoins the contact area, in particular over its entire extent. In addition to the positioning bar, the positioning projection therefore has the entry bridge. The entry bridge is, for example, on the outside to the Positioning web arranged, ie on the outer environment facing sides of the positioning web. Due to this arrangement, the Einfahrsteg gets in the closing of the roof window in front of the positioning web in abutting contact with the positioning. Using the Einfahrsteg so a pre-positioning of the sash is already achieved with respect to the frame before a final positioning using the positioning web or by the interaction of the positioning is effected with the positioning web.

The Positioniersteg and the Einfahrsteg adjacent to each other, so go directly into each other. At the positioning web and the Einfahrsteg is a the frame frame member facing away from positioning, which cooperates with the closing of the roof window with the positioning device for positioning the sash with respect to the frame. In this case, there is a first positioning part surface on the entry bridge and a second positioning part surface of the positioning surface on the positioning projection. The positioning web and the entry web are preferably designed such that the positioning part surfaces merge into one another continuously, ie without jumping.

The entry bridge adjoins the contact area analogously to the positioning bar. In particular, the positioning web and the entry web limit the contact area on different sides. Particularly preferably, the entry web limits the investment area over the entire extent of the investment area. Of course, this can also be the case for the positioning web.

A further embodiment of the invention provides that a longitudinal central axis of the Einfahrstegs runs parallel to a longitudinal central axis of the frame spar, and / or that a longitudinal center axis of the positioning web is angled relative to the longitudinal center axis of the Einfahrstegs. The longitudinal center axis of the Einfahrstegs is in the direction of the largest extension of the Einfahrstegs before. This also applies to the frame spar. The Einfahrsteg should now be arranged parallel to the Blendrahmenholm, so that the longitudinal center axes of the Einfahrstegs and the frame spar also run parallel to each other. Additionally or alternatively, the positioning web is angled with respect to the entry bridge. In this way, the simultaneous abutment of the positioning web and the Einfahrstegs to the contact area can be realized on different sides.

A preferred embodiment of the invention provides that the positioning web is inclined in the direction away from the Einfahrsteg towards the further frame frame spar. The positioning bar seen in plan view from the top surface towards the bottom surface of the frame spar. In particular, it runs parallel to the inner side surface or abuts against it. Here, the positioning web is arranged inclined, namely angled in particular with respect to the Einfahrstegs. The angle is chosen such that the positioning web tapers in plan view of the further frame frame spar. In other words, the positioning web to a longitudinal center axis of the further frame spar receiving and perpendicular to the longitudinal center axis of the frame frame beam imaginary plane on its the positioning web side facing a greater distance than on its side facing away from the Einfahrsteg. The entry bridge preferably runs at least partially straight. For example, it has a first section, which is present on its side facing the entry web and is perpendicular to the entry web. This is followed by another area, which has the longitudinal central axis angled relative to the longitudinal central axis of the entry bridge. This area is straight.

In a preferred embodiment of the invention can be provided that the Einfahrsteg and the positioning web have the same width. Of course, however, different widths can be realized.

A development of the invention provides that the holding part has an end face of the frame frame spar at least partially overlapping, in particular applied to the front side. The frame spar ends with the end face, which preferably lies on its side facing the further frame spar member. This end face adjoins the top surface, the bottom surface, the inside surface and the outside surface of the frame spar. The holding part is now arranged such that it at least partially overlaps this end face. It is preferably also on the front side, so it covers. For this purpose, the holding part has over the front side area.

Such a configuration of the holding part is particularly advantageous if the frame spar is designed as a hollow profile or has such. In this case, the holding part can be arranged such that the end face region covers a hollow chamber of the frame spar, in particular completely closes off from the outside environment. Ingress of moisture in the frame spar or in the hollow chamber is thus prevented by the end face area. Preferably, the end face area is sealingly against the end face. The hollow profile is preferably made of plastic or metal. Alternatively, it can of course also be provided that the frame spar consists of wood or is present in the form of a wooden profile. In this case, of course, the frame spar is protected by the holding part or the front side area from environmental influences.

A further embodiment of the invention provides that the end face region extends in the direction of an upper side surface of the further frame frame spar, in particular with a free edge continuously applied to this. In such an embodiment, it may be provided that the end face region of the frame spar is partially overlapped or covered by the further frame frame spar and partially by the holding part. In particular, in the case of the hollow profile, the hollow chamber or a plurality of hollow chambers present in the hollow profile can be sealingly closed by the further frame spar and the holding part in this manner. For this purpose, the end face region extends as far as the further frame spar member and preferably abuts against its upper side surface.

A preferred further embodiment of the invention provides for a support web for a vertical web of the cover plate, which extends in the direction away from the frame Holstem direction, the support web at least partially on the holding part, in particular from the support area, and / or at least partially from the cover is trained. The support web extends in the direction away from the frame spar Holm, preferably it is perpendicular to the top surface. The support web serves to support or attach the cover plate, in particular the vertical web of the cover plate engages the support web.

For example, the vertical web engages over the support web at least partially. The support web is at least partially on the holding part or at least partially on the cover before. Preferably, a part of the support web is provided on the holding part and a part of the support web on the cover part. The present on the holding part and the cover parts of the support web are preferably aligned with each other, so that from the parts a continuous and straight support web is formed. The support web or the part of the support web present on the holding part preferably starts from the support region.

A further embodiment of the invention provides that the positioning device has a casement web which has a longitudinal central axis perpendicular to a glazing plane of the glazing. The glazing level is from the glazing or defined by glass panes of the glazing. The wing frame web runs perpendicular to the glazing plane or has a corresponding longitudinal central axis. The sash bridge overhangs adjacent portions of the sash so that when the sash is closed, it can come into abutting engagement with the sash for positioning the sash relative to the sash.

Finally, in the context of a further advantageous embodiment of the invention, it is provided that the positioning device has a further sash web which has a longitudinal central axis perpendicular to the glazing plane and a smaller extension in the direction of its longitudinal central axis than the sash web. In this respect, the positioning device has the sash frame web and the further sash web, which are preferably arranged at a distance from one another. Both casement webs, both the casement web and the further casement web, are preferably perpendicular to the glazing plane or have a corresponding longitudinal central axis. However, the further wing frame web has a smaller length than the wing frame web, so a smaller extension in the direction of its longitudinal central axis. In this case, the further sash frame web preferably has the same width as the sash frame web.

For example, the further wing frame web is arranged such that it rests after closing the roof window on the positioning web and / or the Einfahrsteg. Seen in the direction of their longitudinal central axes overlap the wing frame web and the other wing frame web each other. Accordingly, it can be provided that, when the skylight window is closed, both the wing frame web and the further wing frame web abut the positioning protrusion. For example, it is provided that, during the closing of the roof window, the wing frame web initially comes into abutting contact with the positioning projection, in particular with the entry bridge. Subsequently, the wing frame web can be supported on the positioning bar and run along with further closing of the roof window on this. Only shortly before the roof window is completely closed does the further wing frame web come into bearing contact with the positioning projection. This is maintained until the skylight is completely closed. In that regard, when the skylight is closed, two wing frame webs spaced apart from one another bear on the positioning projection, so that a particularly reliable support is realized.

FIG. 5

a representation of a portion of a sash of the roof window, wherein a sash arranged positioning device can be seen.

The FIG. 1 shows a schematic representation of a roof window 1, which has a frame 2 and a sash 3. The sash frame 3 is displaceable relative to the frame 2, in particular rotatable about an axis of rotation, preferably mounted on the frame 2. From the frame 2, a frame spar 4 and another frame spar 5 can be seen. In the context of this description, the further window frame rail 5 is preferably also associated with a fastening device 6 for fastening a roofing frame of the roof window 1 to the roof window 1. On the frame spar 4 at least one cover plate 7 is fixed, of which in particular a vertical web 8 can be seen here.

This has a holding part 10 and a cover 11, wherein the holding part 10 is fixed to the frame spar 4, for example by means of at least one screw 12. The cover 11 in turn is preferably fastened exclusively on the holding part 10 on the frame spar 4. This purpose is served by an unrecognizable form-fitting fastening device 13. The cover 11 serves to hold the cover plate 7. For example, the cover 7 is attached to the cover 11 and held in a form-fitting manner.

On the fastening device 9, a support web 14 may be formed for the vertical web 8. The support web 14 is preferably composed of a first part 15 and a second part 16, the first part 15 of the support web preferably being formed by the cover part 11 and the second part 16 of the support web 14 is preferably formed by the holding part 10. The two parts 15 and 16 of the support bar 14 are preferably aligned with each other. For example, the support bar 14 rests continuously on the vertical web 8 of the cover plate 7.

At the fastening device 6, a positioning projection 17 is formed, which projects beyond a base body 18 of the holding part 10 in the direction away from the frame spar 4 direction. The positioning projection 17 is formed for example by a Einfahrsteg 19 and a positioning projection 20. At the positioning projection 17 is a positioning surface 21 before. This can run parallel to an inner side surface 22 of the frame spar 4. However, it can also be inclined in the direction of the further frame spar 5 away from the inside surface 2, that is to say in the direction of the frame spar 5, it has an increasing distance to it. The positioning projection 17 serves to position the sash frame 3 with respect to the window frame 2 when the roof window 1 is closed by cooperation with a positioning device 23 present on the sash frame 3 (not shown here).

The holding part 10 bears against an upper side surface 24 and the inner side surface 22. In this case, it engages around a frame beam side edge 25, on which the top side surface 24 adjoins the inside surface 22 or vice versa. The holding part 10 has a contact area 26 resting on the upper side surface 24 as well as a contact region 27 which rests against the inner side surface 22. The contact area 27 has, on its side facing away from the frame spar 4, an abutment area side surface 28 which is delimited by the entry bridge 19 and the positioning bar 20. As previously mentioned, the positioning projection 17 projects beyond the abutment area side surface 28.

The cover part 11 has a cover part side surface 29, which preferably runs parallel to the inside surface 22. Additionally or alternatively, the cover part side surface 29 may be parallel to the abutment area side surface 28, in particular aligned with it. In this case, the abutment area side surface 28 and the cover part side surface 29 are on opposite sides of the positioning web 20, so take it between them. It can be spotted, the positioning web 20 or an end face 30 of the holding part 10 adjoining the positioning web 20 represents an end stop for the cover part 11.

The cover part 11 rests with a lower edge 31 on an upper side surface 32 of the further frame frame spar 5. In this case, preferably the lower edge 31 of the cover 11 is aligned with a lower edge 33 of the holding part 10 and the abutment portion 27, which limits the abutment area side surface 28 down. The cover 11 has a covering tongue 34, which rests against an outer side surface 35 of the further frame spar 5 or fastening device 6 and covers them at least in regions. The cover tongue 34 preferably extends as far as a lower edge 36 of the further frame frame spar 5 or the fastening device 6.

It can be clearly seen that the Einfahrsteg 19 is arranged parallel to the Blendrahmenholm 4 and correspondingly has a longitudinal center axis, which is arranged parallel to a longitudinal central axis of the frame frame member 4. The positioning web 20, however, is angled with respect to the Einfahrstegs 19. Preferably, the Einfahrsteg 19 consists of two parts 37 and 38, wherein the first part 37 is perpendicular to the Einfahrsteg 19 and the second part 38 is angled with respect to the first part 37 and also of the Einfahrstegs 19. For example, the angle between the positioning web 20 or its second part 38 and the Einfahrsteg 19 is at least 30 ° and at most 60 °, at least 35 ° and at most 55 °, at least 40 ° and at most 50 ° or exactly 45 °. In this case, the positioning web 20, in particular its second part 38, inclined in the direction of the further frame frame spar 5.

The FIG. 2 shows a further schematic representation of the roof window 1, wherein now the cover plate 7 can be seen in more detail. Reference is made to the above statements. It is clear that the covering tongue 34 closes the cover plate 7 at its end face. In particular, the end face of the cover plate 7 bears against the covering tongue 34. For example, at least one support projection protrudes from the covering tongue 34, which protrudes under the cover plate 7 and supports or carries it.

The FIG. 3 shows a further schematic representation of the roof window 1, wherein the holding part 10 is not shown and the cover 11 and the cover plate 7 are not arranged in their mounting position, but rather in a pre-assembly. It can be seen that the frame spar 4 is present as a hollow profile, in particular hollow plastic profile, or has such. Accordingly, at least one cavity is located in the frame spar 4 39 before. In the cavity 39, for example, a stiffening element 40, in particular made of steel, can be arranged. The frame spar 4 now has an end face 41, which is at least partially overlapped by the latter after the arrangement of the holding part 10 on the frame spar 4. Preferably, the holding part 10 is close to the end face 41, so that the cavity 39 is closed by the holding part 10 weatherproof. Away from the holding part 10 of the window frame 4 is on the other frame spar 5 or is closed by him on its front page 41. Preferably, therefore, the holding part 10 extends up to the top surface 32 of the further frame frame spar 5 in order to completely cover the end face 41 together with the latter, and thus reliably and tightly close the cavity 39 or the cavities 39.

The FIG. 4 shows the roof window 1 without the cover plate 7 and the cover 11 is shown, however, the holding part 10 which is fixed to the frame spar 4. Recognizable is now the form-fitting fastening means 13, which serves for the positive retention of the cover 11 on the holding part 10. The form-fitting fastening device 13 is designed such that the cover member 11 is pushed in the direction of the longitudinal center axis of the frame spar 4 on the holding part 10 and locked with this. The form-fit fastening device 13 serves to produce a preferably releasable latching connection between the cover part 11 and the holding part 10.

The FIG. 5 shows a schematic representation of the roof window 1, wherein now the wing frame 3 can be seen in some areas. On a casement spar 42 of the casement 3, which is present as a vertical spar, the positioning device 23 is arranged or fixed. Preferably, the positioning device 23 bears against an outer side surface 43 of the sash frame spar 42. The positioning device 23 may be fastened to the casement spar 42 by means of at least one screw 44, in the exemplary embodiment illustrated here, two screws 44.

The positioning device 23 has a sash web 45, which is arranged substantially perpendicular to a glazing plane of a glazing of the roof window 1, not shown here. The casement web 45 is arranged such that it comes in a closing of the roof window 1 or a corresponding displacement of the casement 3 relative to the frame 2 in abutting contact with the positioning projection 17. Together with this he pushes the sash 3 in the lateral direction in a desired position. In each case such a positioning device 23 is preferred on both sides of the sash frame 3 arranged, wherein the sash webs 45 protrude laterally in opposite directions. Correspondingly, a plurality of fastening devices 6 or a plurality of positioning projections 17 are arranged on the window frame 2, namely on opposite sides of the roof window 1.

In addition to the sash web 45, another sash web 46 may be provided. This is preferably arranged parallel to the sash web 45, but spaced therefrom. The further sash web 46 has, for example, a smaller longitudinal extension than the sash web 45. It may have the same or a larger overhang than the sash web 45. The supernatant is understood to be the extension in the direction away from the sash 42. The sash webs 45 and 46 preferably have the same width. However, it can also be provided that the wing frame web 46 is wider or narrower than the sash web 45th

The roof window 1 described above has many advantages over known skylights. Thus, it allows a quick assembly due to the integration of the positioning projection 17 in the fastening device 9, which serves to attach the cover plate 7 on the sash 3. In addition, the holding part 10 of the fastening device 9 seals the frame spar 4 on its end face 41 in an advantageous manner.
