Description

The invention relates to a roof window, in particular roof windows, with a frame, a sash and a locking device having at least one locking latch, the sash relative to the frame sets in a closed position in a closed position in a closed position and releases in a release position for opening the roof window. The invention further relates to a method for mounting a roof window.

WO 2012/034558 A discloses the features of the preamble of the first claim.

The roof window or roof window according to the invention has as essential components of the frame and the sash. The casement usually has a glazing, which is present for example as multiple, in particular double glazing or triple glazing. Of course, a single glazing can be realized. The glazing is bordered, for example, by bars of the casement, wherein in particular two vertical bars and two horizontal bars are provided. The frame also preferably has two vertical bars and two horizontal bars. In each case, two of the spars are connected to each other, in particular, each of the vertical beams is connected to each of the horizontal beams.

The frame is provided for example for stationary attachment to a roof or for attachment in a recess of the roof. The casement is movably mounted on the frame and pivotable relative to this at least one axis. The pivoting can be carried out in particular as flaps, swings or swinging. In which Flaps is the axis in an upper region of the roof window, in particular in an upper third of the roof window - in relation to the height - or in the region of the upper edge. By folding the wing frame relative to the frame from a closed position in a first open position or vice versa are brought. For example, in the first open position, the skylight is fully open.

For pivoting, however, the axis lies in a central region of the roof window, in particular in a second third of the height of the roof window. The pivoting serves, for example, to bring the casement from the closed position to a second open position, in particular cleaning position, or vice versa. In the cleaning position, an outer glass surface can be cleaned easily and easily. When swinging, however, the pivoting takes place about several axes, which are usually parallel to each other. For example, when swinging at the same time pivoting about the axis used for the flap and the axis used for pivoting before. The swinging serves, for example, to bring the casement from the closed position into a third open position, in particular a ventilation position.

The roof window also has the locking device. The locking device serves to lock the roof window, so therefore set the sash with respect to the frame in its closed position. Thus, if the roof window is locked by means of the locking device, while the sash is in its closed position, so below is the sash relative to the frame in the closed position fixed until the roof window is unlocked again. However, if the locking device is actuated for locking the roof window, as long as the casement outside the closed position, for example in the open position, it may be provided that no setting of the casement takes place.

The locking device has the locking latch, which can be present in at least two positions, namely the locking position and the release position. In the locked position, the roof window is locked, so the sash set relative to the frame in its closed position. If, on the other hand, the locking bolt is displaced into the release position, then the casement is released so that subsequently the roof window can be opened.

Of course, a plurality of locking bolts, in particular at least two locking bolts, may be provided. The one or more locking bars are preferably arranged on the casement or movably mounted on this. For locking the roof window, for example, they cooperate with a closing block, which is fastened in particular to the window frame. Of course, a reverse arrangement can be realized in which the locking latch on the window frame and the locking block is present on the sash.

It is an object of the invention to provide a roof window, which has over known roof windows advantages, in particular a simpler installation, preferably the locking device allows.

This is achieved according to the invention with a roof window with the features of claim 1. It is provided that the actuating element is held captive in a keyhole-shaped retaining recess of the locking device in a keyhole-shaped holding recess in the retaining recess in a lying outside the actuation range, wherein a push rod is attached to the actuation region, which has a push rod fastening element in a push rod mounting angle position in a push rod receptacle of the actuating element can be introduced and is held in a push rod operating angle position in the push rod receptacle. Such an embodiment of the roof window or the locking device is used in particular to realize a tool-free installation of the actuating element in the retaining recess and the push rod on the actuating element and thus significantly reduce the effort in the assembly of the roof window.

The locking latch is actuated by means of the actuating element and the push rod. For example, the locking bolt via the actuating element and the push rod with a handle, in particular a pivoting handle, the roof window operatively connected. In particular, it is provided that the handle engages the push rod, which engages with its end facing away from the handle on the actuating element. The displacement of the actuating element within the operating range is thus achieved via the push rod by a movement of the handle, in particular a pivoting of the handle.

The actuating element is now operatively connected to the locking bolt, for example via a lever arrangement. The lever arrangement can be designed such that it is present in at least one position of the actuating element in an over-center arrangement. This is the case, in particular, in the case of an embodiment of the roof window in which the closure latch is intended to be operable on the one hand by means of the handle and on the other hand by means of a drive device, in particular an electric drive device.

The actuating element is inserted in the mounting recess of the roof window or the locking device. For this purpose, the actuating element is arranged with respect to the retaining recess in the Betätigungselementmontagestellung in which it can be introduced into the retaining recess. Subsequently, it is displaced from the Betätigungselementmontagestellung in one of this different position, which is preferably within the operating range. The operating region of the actuating element is the region in which the actuating element can be arranged during normal operation of the roof window. In particular, the actuator is in any position of the handle of the roof window in the operating area.

The actuating element and the holding recess are designed such that the actuating element can be used exclusively in the actuating element mounting position in the holding recess or can be removed therefrom. This means that during normal operation of the skylight during which the actuator is always within the operating range is located, the actuator can not get out of the holding recess.

Particularly preferably, it is provided that the actuating element is held by the push rod in the actuating region, in particular as long as the push rod is fastened or hinged on the one hand to the actuating element and on the other hand to the handle of the roof window. In order to be able to remove the actuating element from the holding recess, it is therefore necessary, for example, first to release the connection between the handle and the push rod. Only then is it possible to bring the actuating element in the Betätigungselementmontagestellung and therefore remove it from the holding recess. Thus, the actuator is tool-free fastened in the holding recess.

In addition, however, it can be particularly preferably provided that the push rod can be fastened or articulated without tools, in particular on the actuating element. For this purpose, the push rod on the push rod attachment member and the actuator on the push rod receptacle. The push rod fastening element and the push rod receptacle are now designed such that the push rod fastening element can be introduced into the push rod receptacle only in the push rod mounting angle position.

During normal operation of the roof window, the push rod is in the push rod operating angle position, which is different than the push rod mounting angle position. In the push rod operating angle position, the push rod or the push rod fastener thus securely held in the push rod receptacle. Of course, the push rod operating angle position may be within a push rod operating angular position range in which the push rod is held in the push rod receptacle. The push rod mounting angle position is now outside of this push rod operating angular position range.

The push rod receptacle is designed, for example, keyhole-shaped at least in some areas, that is to say it has a larger-scale area and a smaller-scale area. The dimensionally smaller area is preferably open to the edge, so that the push rod fastening element can be brought into the dimensionally smaller area and through it into the larger-dimensional area. Subsequently, the push rod is displaced from the push rod mounting angle position in the push rod operating angle position. For example, the push rod attachment member has a cross section which is selected such that it can be displaced through the smaller dimension in the push rod mounting angle position, while in the push rod operating angle position it no longer fits into or through it, ie not from the larger dimension range in the dimension smaller area can get.

In other words, and insofar as an alternative and / or supplementary to the above explanations, it is therefore provided that the locking bolt is operatively connected to an actuating element which can be displaced within an actuating region, which in one mounting position lying outside the actuating region Retaining recess of the locking device attachable and is held captive within the actuating portion in the retaining recess. Transferred to the above embodiments, this means that the actuating element can correspond to the actuating element described above, wherein the holding recess of the locking device assigned, for example, in a base plate thereof is formed. However, the actuating element can also be in the form of the push rod, in which case the holding recess corresponds to the push rod receptacle, which is formed in the actuating element. The invention relates in so far quite generally a tool-free installation of at least one element of the locking device, for example of the actuating element and / or the push rod.

A further embodiment of the invention provides that the holding recess has a wider insertion area and a narrower holding area, wherein the actuating element has at least one wing area in which it has smaller dimensions than in the insertion area and larger than in the holding area. The holding recess is configured overall keyhole-shaped, thus has the wider insertion area and the narrower holding area. The holding recess is preferably designed to be closed at the edge, that is, has a continuous inner contour. The holding recess is formed for example in a base plate of the locking device.

The actuating element has the wing region which, for example, has at least one wing which extends in the lateral direction starting from a guide region of the actuating element, in particular with respect to a displacement direction the actuating element within the operating range. The wing region is designed such that it can be introduced through the insertion region of the retaining recess. However, its dimensions, in particular in the lateral direction, are greater than those of the holding area.

A preferred embodiment of the invention provides that adjoins the wing region, a guide portion of the actuating element having dimensions which are at most as large as the dimensions of the holding portion. This applies in particular to the dimensions in the lateral direction. Preferably, the dimensions of the guide region are just as large as the dimensions of the holding region, so that a guidance of the actuating element within the holding recess is achieved by the arrangement of the guide region in the holding region. In that regard, the guide region has an outer contour, which preferably bears against an inner contour of the holding region of the holding recess on both sides when the actuating element is arranged within its actuating region.

A further development of the invention provides that the actuating element has at least one wing in the wing area, on which there is a guide surface, which - in the case of arrangement of the actuating element in the actuating area - is in sliding contact with a counter guide surface of the locking device. As already explained above, the wing region has at least one wing, preferably it has several wings. The wing region or the wings in particular start from the guide region of the actuating element and extend in this case in the lateral direction, preferably on both sides of the guide area.

The wing has the guide surface, which rests against the counter-guide surface of the locking device as soon as the actuating element is displaced in the direction of the actuating region, in particular is located in this. In this case, a sliding contact is present between the guide surface and the counter guide surface, so that a guide of the actuating element is achieved. In particular, however, prevents the concern of the guide surface on the mating guide surface, that the actuating element can get out of the holding recess.

A preferred embodiment of the invention provides that the holding recess is present in a base plate of the locking device. This has already been pointed out above. The base plate is preferably a rigid element and is preferably made of metal.

A further preferred embodiment of the invention provides that the actuating element on the wing opposite to the base plate side has a support surface which is in sliding contact with a present on the base plate counter-support surface. The actuating element therefore has, in addition to the guide surface, the support surface. Preferably, the guide surface and the support surface are opposite. In particular, the guide surface lies in an imaginary plane, which is arranged parallel to an imaginary plane in which the support surface lies. Accordingly, the mating surface and the mating support surface are preferably on opposite sides of the base plate.

The guide surface and the support surface preferably have a distance from each other, which corresponds to the thickness of the base plate, so that at the same time the guide surface with the mating guide surface and the support surface with the mating support surface may be in touching contact or in sliding contact with an arrangement of the actuating element in the retaining recess. The base plate is held so far between the guide surface and the support surface. The guide surface and the support surface preferably have an extension in the lateral direction and in the longitudinal direction, which prevents tilting of the actuation element relative to the base plate. The extensions of guide surface and support surface, in particular in the lateral direction, can be the same. However, they can also be chosen differently from each other.

In a further preferred embodiment of the invention, it is provided that the push rod receptacle has a bearing eye and a guide opening opening into the bearing eye, wherein the bearing eye has a diameter which is smaller than the width of the guide opening, and wherein the push rod fastening element has a thickness which is smaller is as the width of the guide opening, and has a width which is greater than the width of the guide opening. The push rod or the push rod fastening element can be introduced through the guide opening in the bearing eye. In the bearing eye, it is subsequently rotatably mounted, in particular such that it can be shifted from the push rod mounting angle position into the push rod operating angle position, in particular turned, can be. The bearing eye is preferably round and has the diameter, which is smaller than the width of the guide opening. The width of the guide opening is defined in particular as the smallest dimension of the guide opening. The push rod fastening element, however, is designed with a thickness which is smaller than the width of the guide opening. Under the strength is for example to understand a material thickness of the push rod attachment element or the push rod itself. The strength is, for example, seen in longitudinal section perpendicular to a longitudinal extension of the push rod, wherein the longitudinal extent of the largest extension of the push rod is to be understood. By contrast, the width of the push rod fastening element is, for example, in the longitudinal direction, in any case in a direction which is perpendicular to the direction in which the strength of the push rod fastening element is present.

The width of the push rod fastening element should now be greater than the width of the guide opening. In that regard, it is clear that the push rod attachment member is formed such that it is in an orientation or position, in particular the push rod mounting angle position, introduced through the guide hole in the bearing eye, but not in a different position of the push rod mounting angle position, for example, the push rod operating angle position. This analogously of course also applies vice versa, so that the push rod attachment element can not get out of the bearing eye in the guide hole and thus from the push rod receptacle after arrangement in the push rod mounting angle position however, if the push rod is in a different position from the push rod mounting angle position.

A further embodiment of the invention provides that the base plate is clipped to a holding frame. The support frame consists for example of plastic. Alternatively, a metal version is conceivable. In any case, the base plate and the holding frame are designed such that a tool-free mounting of the base plate can be done on the support frame, in particular by clipping or pressing. When clipping at least one elastic locking element is provided, which is deflected during clipping from its elatisch starting position and subsequently at least partially back towards the starting position, so that it engages behind the latching element, ie the base plate or the holding frame, latching or form-fitting. For example, the holding frame is designed such that it surrounds the base plate at least partially, in particular completely.

Finally, it can be provided that the locking device is associated with at least one centering a centering device, which cooperates with a closing of the roof window arranged on a closing block of the roof window Zentriergegenelement for centering the sash with respect to the frame. In order to ensure a particularly good smoothness of the roof window when opening or closing one hand, and reliable locking on the other hand, the centering device is provided. This serves to position the casement with respect to the frame when closing the roof window in such a way that the locking latch reliable with the corresponding counter-element, such as the lock block, can cooperate to lock the roof window. The centering is preferably carried out in the lateral direction.

The centering device has at least one centering element, but preferably a plurality, that is, at least two centering elements. The at least one centering element is attached to the base plate, for example. When closing, the centering element cooperates with the centering counter-element for centering the sash frame with respect to the window frame. The centering counter-element is present, for example, on the closing block, so that the centering device is completely integrated in the locking device and the associated closing block.

The invention further relates to a method for mounting a roof window according to the preceding embodiments, wherein the roof window has a frame, a sash and a locking device having at least one locking latch, which sets the sash in a closed position with respect to the frame in a closed position and in a release position for opening the roof window releases.

It is provided that the closure bolt is operatively connected to a displaceable within an operating range actuator which is placed in a lying outside the operating range Betätigungselementmontagestellung in a keyhole-shaped holding recess of the locking device and within the operating range in the holding recess is held captive, wherein on the actuating element a push rod is fixed, which has a push rod fastening element which is introduced in a push rod mounting angle position in a push rod receptacle of the actuating element and is held in a push rod operating position in the push rod receptacle.

The advantages of such an approach or such an embodiment of the roof window has already been pointed out. Both the method and the roof window can be developed according to the above statements, so that reference is made to this extent.

For example, it is provided in the mounting of the roof window, to arrange the actuating element in the Betätigungselementmontagestellung with respect to the holding recess and subsequently introduce into this. Subsequently, the actuating element is moved out of the Betätigungselementmontagestellung, for example in the direction of the actuation area or in this.

Subsequently, it may be provided to connect the actuating element via the above-mentioned lever arrangement with the locking bolt. The lever arrangement preferably holds the actuating element within the actuating region, so that it can no longer get out of the holding recess.

Subsequently, it may be provided to attach the push rod to the actuating element. For this purpose, the push rod is arranged in the push rod mounting angle position and its push rod fastening element in the push rod receptacle introduced the actuating element. Then, the push rod is displaced out of the push rod mounting angle position or rotated, in particular in the push rod operating position. Accordingly, the thrust position is now held captive on the push rod.

In order to prevent the push rod from re-entering the push rod mounting angle position, it may be provided to subsequently connect it to the handle of the roof window, in particular the pivoting handle. This is preferably done by clipping the handle onto the push rod or onto an end of the push rod facing away from the actuating element.

The FIG. 1 shows a roof window 1, in particular a rooftop window. This has a frame 2 and a relative to the frame 2 movably mounted sash 3. The casement 3 carries a glazing 4 of the roof window 1. The window frame 2 is preferably fixedly mounted in a roof or the like. For attachment of the frame 2, at least one fastening element 5 may be provided, which is present for example in the form of a mounting bracket. The fastener 5 is preferably bolted to both the frame 2 and the roof.

The frame 2 consists of several spars, similar to a lower horizontal spar 6, an upper horizontal spar 7, a left vertical spar 8 and a right vertical spar 9. Analogously, preferably the wing frame 3 consists of a plurality of spars, which are not shown in detail here. The frame 2 and / or the sash 3, in particular their spars, for example, the spars 6, 7, 8 and 9, may be provided with at least one cover. The cover member serves to cover against an outside environment, so that environmental conditions can not negatively affect the roof window 1.

As a cover, for example, one or more of the following elements may be present: an upper Flügelabdeckblech 10, a water protection plate 11, upper Flügelseitenabdeckbleche 12, lower Flügelseitenabdeckbleche 13 and side cover frame plates 14. The cover frame plates 14 close in the lateral direction of the Flügelseitenabdeckbleche 12 and 13 at. The Flügelabdeckblech 10 is connected by means of connecting elements 15 with the upper Flügelseitenabdeckblechen 12. Similarly, the water protection plate 11 is connected via connecting elements 16 with the lower Flügelseitenabdeckblechen 13.

The FIG. 2 shows the roof window 1 according to the above and cover 17, 18, 19 and 20. The cover 17, 18, 19 and 20 may be present, for example, as separately formed cover plates. In particular, they form a cover frame 21 for the roof window 1. The cover 21 and the cover 17, 18, 19 and 20 serve to discharge water from the roof window 1 in the direction of the roof. For this purpose, the cover element 17 has a cover skirt 22 which can be adapted to a shape or a structure of the roof. It is clear that the skylight 1, in particular the casement 3, a handle 23, in particular a pivoting handle, which serves to actuate the roof window 1.

The FIG. 3 shows a locking device 24 of the roof window 1, which has at least one locking latch 25 which is arranged displaceably in a locking bolt receptacle 26. In the illustrated embodiment, two locking latch 25 and correspondingly two locking bolt receptacles 26 are provided. In principle, however, any number of locking bolts 25 and locking bolt receptacles 26 may be present. The locking device 24 is used to lock the roof window 1. It is preferably arranged on the casement 3 and actuated by the handle 23.

With the aid of the handle 23, in particular, a force directed to pivoting of the sash frame 3 with respect to the window frame 2 can thus be applied to the sash frame 3. On the other hand, the handle 23 serves to actuate the locking device 24 or to displace the locking bolt 25 in the locking bolt receptacle 26. The locking bolt 25 can assume a plurality of positions, in particular at least one locking position and a release position.

In the locking position of the sash frame 3 is fixed relative to the frame 2 in its closed position. Thus, if the roof window 1 is locked or brought the locking latch 25 in the locking position, while the sash 3 is in its closed position, the sash 3 is set below in this. Accordingly, the roof window 1 can not be opened. This is only possible again when the locking bolt 25 is displaced into the release position. In this, the sash 3 is released to open the roof window 1.

For locking the roof window 1, the locking device 24 or the locking bolt 25 preferably cooperates with a closing block 27 (not shown here), which is fastened to the window frame 2, for example. Of course, a reverse configuration is possible in which the locking device 24 is arranged on the frame 2 and the closing block 27 on the sash 3.

The locking bolt receptacle 26 is preferably formed in a base plate 28 of the locking device 24. The base plate 28 may be attached to a support frame 29 or at least partially received by this. Particularly preferably, the base plate 28 is clipped into the holding frame 29. For this purpose, for example, at least one locking element 30 is provided, which holds the base plate 28 in a form-fitting manner on the holding frame 29. In the embodiment shown here, a plurality of locking elements 30, namely at least two locking elements 30, are provided.

The holding frame 29 serves in particular for a spacing of the base plate 28 from a mounting surface (not shown), which may be present on the casement 3 or the frame 2. For example, the locking device 24, in particular the base plate 28, by means of at least one screw to the sash 3 and the window frame 2 is fixed. For this purpose, the base plate 28 may have at least one screw hole 31 (here: three screw holes 31).

The locking device 24 may be associated with at least one centering element 32 of a centering device 33. Here are two centering elements 32 are provided. These may be attached to the base plate 28. The at least one centering element 32 preferably interacts with a centering counter-element 34 (not illustrated here) when the roof window 1 is closed, in order to center the casement 3 with respect to the window frame 2. In this way, a particularly reliable and tight closure of the roof window on the one hand and a reliable locking using the locking device 24 on the other hand is achieved. The at least one centering counter-element 34 is preferably formed or arranged on the closing block 27.

The at least one locking bolt 25, in the exemplary embodiment illustrated here, thus both locking bolt 25, are operatively connected to an actuating element 35, which is displaceable within an operating range. The actuating element 35 is arranged in a retaining recess 36 of the locking device 24. Preferably, the retaining recess 36 is formed in the base plate 28, in particular edge-closed. The holding recess 36 is keyhole-shaped and thus has a wider insertion area 37 and a narrower holding area 38. The width of the insertion region 37 and of the holding region 38 is preferably in a direction which is perpendicular to a longitudinal central axis 39 of the holding recess 36 and lies in a plane defined by the extent of the base plate 28. The longitudinal central axis 39 preferably also corresponds to a displacement direction of the actuating element 35. This is thus held displaceable along the longitudinal central axis 39 in the retaining recess 36.

The FIG. 4 shows the closing block 27 of the roof window 1. The closing block 27 is preferably attached to the frame 2. When closing the roof window 1, the locking bolt 25 is inserted in the direction of the arrow 40 in the closing block 27. It may be provided that the closure latch 25 comes into contact with a guide projection 41. The guide projection 41 urges the locking bolt 25 in a further closing of the roof window 1 in the direction of the arrow 42, in particular in the lateral direction outwards until the locking bolt 25 is arranged in locking receptacle 43.

The guide projection 41 thus urges the closure latch 25 when closing the roof window 1 from its release position into its locking position. In the locking position of the locking latch 25 is in the Verrieglungsaufnahme 43, in which it is held positively. The roof window 1 can not be opened accordingly. In order to open the roof window 1 again, the locking latch 25 must be moved out of the locking receptacle 43, wherein this is provided opposite to the arrow 42 of the arrow. This displacement of the closure bar 25 can be achieved in particular by an actuation of the handle 23.

The FIG. 5 shows a detailed view of the actuating element 35. The actuating element 35 has a wing region 45 with at least one wing 45, but preferably a plurality of wings 45 on. In the embodiment shown here, two wings 45 are provided. The wing area 44 is adjoined by a guide area 46 of the actuating element 35. On the wing 45 and on each wing 45 is a guide surface 47 before. This opposite is a support surface 48 formed on the actuating element 35. Preferably, as many guide surfaces 47 as support surfaces 48 are provided on the actuating element 35, in particular two in each case.

The actuating element 35 now has smaller dimensions in its wing region 44 than the insertion region 37 of the retaining recess 36, but at the same time larger than the retaining region 38. This is particularly preferably provided both in the lateral and in the axial direction (with respect to the here indicated longitudinal central axis 39 of the holding recess 36). In the guide region 46, however, the actuating element 35 has dimensions which are at most as large as the dimensions of the holding region 38, in particular in the lateral direction. In particular, the dimensions of the actuating element 35 in its guide region 46 correspond to the dimensions of the holding region 38 of the holding recess 36 in order to achieve reliable longitudinal guidance of the actuating element 35 in the holding recess 36.

Particularly preferably further corresponds to the distance in the vertical direction between the guide surface 47 and the support surface 48 of a thickness or thickness of the base plate 28 in this direction. Accordingly, both the guide surface 47 and the support surface 48 are permanently on the base plate 28 at least partially, at least as long as the actuator 35 is within its operating range. Visible in the representation selected here is also a push rod receptacle 49 for a push rod 50, not shown here.

The FIG. 6 shows a frontal representation of the actuating element 35. It can be seen that the actuating element 35 has at least one bearing pin 51 on which a lever assembly (not shown) engages, via which the actuating element 35 is operatively connected to the closure latch 25. Furthermore, a fastening pin 52 is provided, on which, for example, a spring element, not shown here, is attached or acts.

The FIG. 7 shows a detailed view of the arranged in the holding recess 36 actuating element 35. The actuating element 35 is present in an Betätigungselementmontagestellung, in which the wing portion 44 is disposed completely in the insertion region 37 of the holding recess 36. Because the wing region 44 has dimensions at least in the lateral direction which are smaller than the dimensions of the insertion region 37, the wing 45 or the vanes 45 can be introduced into the retaining recess 36 through the insertion region 37 and emerge from the latter on the opposite side. Thus, therefore, the guide portion 46 in the holding recess 36 before.

In the FIG. 8 again, the actuating element 35 is shown in the retaining recess 36, but in a different from the Betätigungselementmontagestellung first position. In this, the actuating element 35 is displaced along the longitudinal central axis 39 in the direction remote from the insertion region 37. Accordingly, the at least one wing 45 is no longer in the region of the insertion region 37. Rather, the guide portion 46, which is provided on the wing 45, on a mating guide surface 53 at. Preferably, each guide surface 47 and consequently each vane 45 is assigned such a counter-guide surface 53. Accordingly, in each case on both sides of the holding recess 36 in each case before such a counter-guide surface 53. Due to the concerns of the guide surface 47 on the mating guide surface 53, the actuating element 35 can not get out of the holding recess 36.

The FIG. 9 shows the arranged in the retaining recess 36 actuator 35 in a second position, which also of the Betätigungselementmontagestellung is different. In particular, in the second position, the actuator 35 is located further from the actuator assembly position than in the first position. In the illustration shown here, moreover, the support surface 48 can be recognized at least in the beginning. This is applied to a mating support surface 54 of the base plate 28. The counter guide surface 53 and the counter support surface 54 are arranged on opposite sides of the base plate 28.

The base plate 28 is thus arranged between the guide surface 47 and the support surface 48 of the actuating element 35, so that the actuating element 35 is held securely on the base plate 28 as long as it is in its operating region. The Betätigungselementmontagestellung lies outside the operating range.

The FIG. 10 shows a side sectional view of the locking device 24. In particular, the actuating element 35 can be seen. Here it can be seen that the push rod 50 is arranged in the push rod receptacle 49. The push rod receptacle 49 has a bearing eye 55 and a guide opening 56. The guide opening 56 and thus the push rod receptacle 49 are formed open-edge in the fastener 35. Through the guide opening 56, the push rod 50, in particular a push rod attachment member 57 in the bearing eye 55 can be introduced, provided that the push rod 50 is present in a push rod mounting angle position. This one is shown here.

The FIG. 11 again shows the side sectional view of the locking device 24. Here, however, now the push rod 50 from the Push rod mounting angle position shifted out into a push rod operating angle position. The push rod attachment member 57 is configured such that when the push rod is arranged in the push rod mounting angle position it can pass into or through the guide opening 56, both in the direction of the bearing eye 55 and out of it. At the same time, however, the push rod attachment member 57 is configured such that it can not pass into or through the guide opening 56 at an angular position of the push rod 50, which is different from the push rod mounting angle position, for example, the push rod operating angle position. Accordingly, in the push rod operating angle position shown here, the push rod 59 or its push rod fastening element 57 is securely held in the bearing eye 55.

The FIG. 12 shows a detailed view of a portion of the push rod 50. In particular, the push rod attachment member 57 is shown, which is in the form of a web at a free end of the push rod 50 is formed. Adjacent to the push rod attachment member 57 is a recess 58, preferably closed at the edge, formed in the push rod 50. In this can engage the actuator 35 at least partially to the arrangement of the push rod 50 in the push rod operating angle position. In that regard, the push rod attachment member 57 by its engagement in the push rod receptacle 59 and the actuator 35 by engaging in the recess 58 a positive connection between the actuator 35 and the push rod 50 ago. Edges of the push rod attachment member 57 are preferably each provided with a rounding 59 or at least one phase. In the case of a rounding, the radius of the rounding preferably corresponds to the radius of the bearing eye 55 to allow a displacement of the push rod 50 or a tilting of the push rod 50 from the push rod mounting angle position in the push rod operating angle position without entanglement or with low resistance.

The FIG. 13 illustrates the function of the above-mentioned centering device 33 with the at least one centering element 32. As already mentioned, the centering counter-element 34 should be provided on the closing block 27, which, for example by means of screws 60, preferably attached to the frame 2. The centering counter-element 34 is present here in the form of a centering surface, which is provided in the inlet direction of the centering element 32 with an inclined run-on slope or a rounding 61. In the exemplary embodiment illustrated here with two centering elements 32 and two centering counter-element 34, the latter are received in a closing of the roof window 1 between the centering elements 32. In the illustration selected here, the centering device 33 is shown with the roof window 1 still partially open.

The FIG. 14 again shows the centering device 33, but the roof window 1 is completely closed. It becomes clear that the centering elements 32 now receive the centering counter-element 34 between them and thus center. In a deflection of the sash 3 with respect to the frame 2 in the lateral direction, the rounding 61 or bevel provides for a reliable centering of the sash frame 3 with respect to the frame 2. The integrated design of the centering device 3 with the locking device 24 and the closing block 27, this centering is realized with an extremely low cost. In particular, no additional devices to be provided on the roof window 1.
