Description

The invention relates to an actuator assembly for a building closure, comprising a locking device having at least one locking latch, which sets in a locking position a wing of the building closure with respect to a frame in a closed position and releases in a release position for opening the building closure, wherein the actuating arrangement is a mechanical building closure drive comprising a drive element which can be stored on the frame and a holding part assigned to the leaf, wherein the drive element is released in a first position of the holding part and fixed in a second position with respect to the holding part, the holding part being operatively connected to the closure latch, that in the first position of the holding part of the locking latch is in its locking position and in the second position of the holding part in its release position.
In principle, the building closure can be configured as desired. For example, it is in the form of a window, in particular a facade window, a roof window, a door or the like. The façade window can be realized in particular as a louvre window, rotary windows, tilting windows, folding windows or Parallelausstellfenster. A design as a dome light, dark or emergency exit can be provided. The building closure preferably has as essential components the (at least one) frame and the (at least one) wing. Of course, the building closure can in this respect also have several frames and / or several wings, for example in the Trap of the louvre window, whereby each lamella can be regarded as a wing. These wings are preferably coupled together or operatively connected.

The wing can be referred to in the case of the window as a sash and the frame as a frame. The wing 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 spars of the wing, wherein in particular two vertical spars and two horizontal spars 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 fixed attachment to a building, in particular a roof, or for fastening in a recess of the building or of the roof. The wing is movably mounted on the frame and so far displaced so that it can be moved from a closed position to an open position and vice versa. In this case, any number of intermediate positions can be provided. Preferably, the building closure is fully open in the open position.

For example, the wing, in particular in the case of the roof window, relative to the frame about at least one axis pivotable. The pivoting can be carried out in particular as flaps, swings or swinging. At the flap the axis is 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 relative to the frame from the closed position can be brought into a first open position or vice versa. 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 wing 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 wing from the closed position into a third open position, in particular a ventilation position.

The building closure or the actuating arrangement has the locking device which has the at least one locking bolt. The locking device serves to fix the wing in its closed position with respect to the frame, thus preventing an opening of the building closure. For this purpose, the locking device on the locking latch, which is present for example on the wing or can be arranged on this and cooperates with a closing block, which may be provided on the frame. So long as the locking latch is in its locking position, it prevents so that the wing is moved out of the closed position.

If, on the other hand, the wing is already in a position different from the closed position, for example the open position, it is preferable that the wing is not locked by the locking bolt. In the release position, the wing can easily be moved out of a closed position, in particular in the direction of the open position or one of the open positions.

If a plurality of mutually coupled wings are provided, then the locking device is preferably associated with only one or a part of the wings, ie acts directly only on these or these. The other wings are only indirectly acted upon by the locking device. Of course, however, the locking device can also act directly on each of the wings.

From the prior art, for example, the publication EP 0 792 991 A1 known. This relates to a coupling device to connect an electric window actuator with an actuator. Furthermore, the document describes WO 2006/089545 A1 a releasable coupling and the publication US 5,406,751 an electrical actuator for doors and windows.

It is an object of the invention to propose an alternative actuating arrangement which enables a machine opening and / or closing of the building closure in a particularly simple manner.
This is achieved according to the invention with an actuating device having the features of claim 1. It is provided that the drive element is present as a form-fitting element and the holding part has a form-fitting recess, wherein the holding part are associated with respect to their respective longitudinal central axis rotationally symmetrical formed rear grip elements which engage in the second position of the holding part the drive element for fixing with respect to the holding part, or that Drive element has the form-fitting recess and the holding part is designed as a form-locking element, wherein the drive element, the two associated with respect to their respective longitudinal central axis rotationally symmetrical locking elements are assigned, which engage behind the holding part for fixing with respect to the drive element in the second position of the holding part. In principle, it is provided that a mechanical building closure drive has a drive element mounted and storable on the frame and a holding part associated with the wing, wherein the drive element is released in a first position of the holding part and fixed in a second position with respect to the holding part, wherein the holding part in such a way is operatively connected to the locking latch, that in the first position of the holding part of the locking latch is in its locking position and in the second position of the holding part in its release position.

The mechanical building closure drive is part of the actuator assembly and serves in particular to effect the opening or closing of the building closure without a user having to attack directly on the wing. The mechanical building closure drive can still be operated manually, with an opening or closing of the building closure is effected by muscle power of the user, which does not act directly on the wing but rather on the building closure drive on this. However, the mechanical building closure drive is particularly preferably an electrical building closure drive which, in this respect, provides the force required to open or close the building closure by means of an electric actuator, for example an electric motor.

The building closure drive has the drive element and the holding part. The drive element is movably mounted or storable on the frame, so that it can be displaced, in particular starting from the frame in the direction of the wing or in the direction of the holding part. The holding part, however, is assigned to the wing or attached thereto. The holding part is preferably displaced together with the wing so far, if a movement of the wing takes place.

As far as the wing is mentioned, it is - if more, in particular coupled together wings - preferably always meant only one of the wings. The other wings are acted upon only indirectly via the coupling or operative connection of the building closure drive. Of course, the building closure drive alternatively with several the wing directly connected to or more of the wings each associated with a building closure drive.
The displacement of the wing with respect to the frame is preferably achieved by an interaction of the drive element and the holding part. For the opening of the building closure, for example, the drive element is displaced in the direction of the wing, so that it displaces the holding part such that the wing is displaced to open the building closure. In particular, the drive element urges the holding part for this purpose away from the frame, in particular a bearing point of the drive element on the frame.
For closing the building closure, however, it can be provided that the drive element again moves the holding part in the direction of the frame, in particular in the direction of the bearing point, in particular dragging or pulling. For example, it can be provided that either the opening or the closing of the building closure is supported by the influence of gravity by the wing is urged or displaced by gravity in the direction of the open position or the closed position. This is dependent on the bearing of the wing on the frame, in particular an arrangement of the axis about which the displacement or pivoting is to take place.

The holding part is not rigidly attached to the wing, but with respect to the wing in several positions can be arranged, in particular in the first position and the second position. The holding part is in its first position, the drive element is released with respect to the holding part, so it can in principle be moved arbitrarily. It is not fixed with respect to the holding part. However, this is the case in the second position of the holding part. This means that the drive element with respect to the holding part can not be displaced as long as this is in the second position. In particular, a driving force provided via the drive element is transmitted to the wing only when the holding part is in its second position.
The holding part is now operatively connected to the locking latch, so that a displacement of the holding part also causes a displacement of the locking bolt. An assignment of the positions of the holding member to the positions of the locking bolt is provided as follows: In the first position of the holding part of the locking bolt should be present in the locking position and in the second position of the holding member in the release position. The operative connection between the holding part and the locking bolt can basically be made as desired, in particular, it is above a lever arrangement.
With such a configuration of the actuator assembly or the building closure, it is possible to couple the mechanical building closure drive only when needed with the wing. It is therefore envisaged that the mechanical building closure drive or its drive element only cooperates with the wing or is coupled to this when actually a displacement of the wing, for example, the opening or closing, should be done using the building closure drive.

For example, the drive element is spaced from the holding part, when the wing is in its closed position, so does not attack on the holding part or is not coupled thereto. Accordingly, a manual operation of the building closure or a manual opening of the building closure can take place in a simple manner. In particular, it is not necessary for the building shutter drive to be decoupled from the wing beforehand because this is already the case.

If, on the other hand, the building closure is to be opened by means of the building closure drive, then the drive element enters into operative connection with the holding part. Subsequently, this is shifted from its first position to the second position. Accordingly, the drive element is fixed with respect to the holding part below. Now, a driving force can be applied to the wing via the drive element, in particular initially directed to the opening of the building closure driving force.

If the building closure has been opened by means of the building closure drive, ie if the drive element is fixed relative to the holding part, the building closure can subsequently be closed by means of the building closure drive. This means that the drive element remains operatively connected to the holding part after opening the building closure by means of the building closure drive until the building closure has been closed again using the building closure drive. Only after or when closing the holding part is moved back to its first position, so that the drive element with respect to the holding part and thus the wing is released.

After closing the building closure using the building closure drive so the drive element is again spaced from the holding part and the manual operation of the building closure is again easily possible. Overall, therefore, there is a need-based coupling or coupling of the building closure drive to the wing of the building closure.
In this case, the components of the actuating arrangement, namely in particular the building closure drive and the locking device cooperate to effect not only the displacement of the wing with respect to the frame, but at the same time unlocking and / or locking using the locking device. This is accomplished with the operative connection between the holding part and the locking bolt.
A further embodiment of the invention provides that the drive element can be mounted on the frame by means of a transmission element, in particular a pressure-resistant transmission element. As already stated above, the drive element is displaced with respect to the frame when the building closure is to be opened or closed by means of the building closure drive. The necessary for this shift storage on the frame is realized via the transmission link. The transmission member can basically be configured as desired, preferably it is pressure-resistant to be able to apply a compressive force on the wing, starting from the bearing point.
For example, the transfer member is in the form of a rod. However, it is particularly preferably designed as a chain, wherein the Chain can be rigid or pressure-resistant. This means, in particular, that members of the chain, which have already been displaced together with the drive element in the direction of the sash, can absorb pressure forces or transmit them to at least one adjacent member. By contrast, limbs which have not yet been displaced in the direction of the casement or, for example, are still in a corresponding receptacle of the frame, are preferably mounted flexibly on adjacent links in order to realize a space-saving arrangement of the chain. For example, the chain is designed as a rigid chain that can transmit both tensile and compressive forces.

A particularly preferred embodiment of the invention provides that the drive element has a contact surface which comes into contact with a counter-bearing surface of the holding part in a displacement of the drive element in the direction of the holding part, so that the drive element, the holding part in its second position and / or the wing in Pushing for an open position. About the contact surface, the drive element can cause a compressive force on the counter-contact surface and thus the holding part and the wing.

If the building closure is closed, the wing is thus in the closed position, then the holding part is preferably in its first position. Now, if the opening of the building closure by means of the mechanical building closure drive is desired, the drive element is displaced in the direction of the wing or the holding part. In this case, the drive element occurs with its contact surface in touching contact with the holding part, more precisely its counter-contact surface.

If the drive element is now displaced further in the direction of the wing, the driving force initially acts on the retaining part. This causes the displacement of the holding part in its second position. This means that at the same time the locking latch is moved to its release position, so that the building closure is unlocked below. The driving force continues to act on the support member on the wing, being directed to opening the building closure. After unlocking the building closure by moving the holding part to its second position so the drive element can push the wing in the direction of its open position, so that the opening of the building closure takes place.
The invention provides that the drive element is present as a form-locking element and the holding part has a form-fitting recess, wherein the holding part are associated with two rotationally symmetrical with respect to their respective longitudinal central axis formed rear grip elements, which engage behind the drive element for fixing relative to the holding part in the second position of the holding part. The setting of the drive element with respect to the holding part should therefore be done by positive locking. The drive element engages in the holding part. If the drive element is present in the holding part, then the rear grip element should produce the positive connection to the drive element.
For example, this is effected by the displacement of the holding part in its second position. In particular, it is provided that the rear grip element is freely displaceable in the first position of the holding part, so that any possible rear grip connection to the drive element can be released by displacement of the drive element from the holding part out. If, on the other hand, the holding part is in the second position, then the rear grip element is present set or is urged at least in the direction of the drive element, so that the rear grip connection to this is not solvable.
Alternatively, however, it is also possible that the drive element has the form-fitting recess and the holding part is designed as a form-locking element, wherein the drive element, the two rotationally symmetrical with respect to their respective longitudinal central axis formed behind the locking elements, in the second position of the holding part, the holding part for fixing with respect to the drive element engage behind. In that regard, the embodiment described above with the same elements, but realized exactly the opposite. The above statements can therefore be used analogously.
In a preferred embodiment of the invention it is provided that the rear grip element is mounted with respect to the holding part. The storage of the rear grip element with respect to or on the holding part can basically be configured arbitrarily. For example, a pin is provided for storage, which is rigidly attached either to the rear grip element or to the holding part, the other element, ie the rear grip element or the holding part, however, keeps movable with play.
It can be provided that the rear grip element has an edge-closed recess, which is penetrated by the rigidly fixed to the holding part pin and seen in cross section has larger dimensions than the recess. Alternatively, the holding part may have a slot or a plurality of elongated holes into which or in which the pin rigidly attached to the rear grip element engages to realize a guide. The pen is preferably arranged centrally on the rear grip element. However, an off-center and so far eccentric arrangement is feasible.
The rear grip element may in particular be mounted eccentrically on the holding part. This means, for example, that the axis of rotation about which the bearing is provided does not coincide with the longitudinal center axis of the rear grip element. Preferably, the two axes are provided spaced parallel to each other. Preferably, in this case, the pin is mounted eccentrically in the rear grip element. He may be rigidly attached to the holding part in this case. A pivot bearing of the then rigidly and eccentrically attached to the rear grip element pin in the holding part can be provided. Of course, a plurality of these rear engagement elements may be provided, which preferably engage on opposite sides of the drive element for producing the rear grip connection. It can be provided that the rear grip element is round in cross-section. It has, for example - seen in cross section - a circular outer circumference or a circular contour. The cross-section is to be understood with respect to a longitudinal center axis of the rear grip element, with respect to which the rear grip element is rotationally symmetrical. For example, the rear grip element is roller-shaped or barrel-shaped, wherein in the latter case - seen in longitudinal section - the rear grip element has a belly, which in particular bulges outwards, so far convex.

A further preferred embodiment of the invention provides that the holding part is associated with a displacement element which urges in the second position of the holding part the rear grip element in a rear grip position in which the rear grip element engages behind the drive element. The displacement element is used in this respect the displacement of the rear grip element or the plurality of engagement elements.
For example, the displacement element for this purpose has an inclined surface which releases the rear grip element in the first position of the holding part and in the second position pushes in the direction of the rear grip position or into it. It may be provided that the holding part is arranged in the first position at least partially outside of the displacement element, while it further engages in the second position in this, in particular largely present in this. The displacement element may be referred to as a displacement recording or as a displacement housing.

In a particularly preferred embodiment of the invention it is provided that the operative connection between the locking bolt and the holding part is present via a lever arrangement which is arranged in the second position of the holding part in an over-center position. The lever arrangement is configured, for example, such that the drive force transmitted via the drive element, which is directed in the direction of the wing, can displace the holding part from its first position into its second position. The lever arrangement reaches its over-center position. This subsequently prevents one from closing the building closure directed driving force, which in turn is transmitted via the drive element, a displacement of the holding part from the second position out, in particular up to the first position causes.
Thus, if the holding part is in its second position, it is achieved with the special configuration of the lever arrangement that the driving force acting on the holding part via the drive element can not effect any displacement from the second position. In that regard, the drive element is always safe with respect to the holding part and thus the wing fixed after opening the building closure using the building closure drive. Correspondingly, a drive force directed towards closing the building closure can also be impressed on the wing via the drive element. A further preferred embodiment of the invention provides that the locking device has a closing block, which urges the locking bolt in its locking position by means of at least one inclined surface upon closure of the building closure. The closing block is preferably arranged or fastened to the frame. The closing block cooperates with the closed building closure and corresponding arrangement of the locking bolt with this to fix the wing in the closed position.
The closing block now has the at least one inclined surface. Preferably, each locking bolt is associated with such an inclined surface. The inclined surface dominates when closing the building closure or during closing contact contact of the closure bolt with the inclined surface on a force on the locking bar, which pushes the locking bolt in the direction of its locking position or into this. The inclined surface is preferably designed such that when it reaches the closed position by the wing of the locking bolt also reaches its locking position, so that after complete closure of the building closure this is locked at the same time.

Likewise, it may of course be provided that the locking device is manually operated, in particular by the locking bolt is manually urged into its locking position. Because the operative connection is present between the locking bolt and the retaining part, the retaining part can be displaced out of the second position, preferably as far as the first position, by the manual actuation of the locking bolt. Accordingly, the drive element is released, so that subsequently the building closure can be easily opened or closed manually. Such a procedure is provided for example for auditing purposes or emergency closing of the building closure. For example, can be made by manually operating the shutter bolt in case of power failure or a defect of the electric actuator, the emergency closing.

The operative connection between the holding part and the locking bolt is designed in such a way that the force impressed on the locking bolt, manually or by the oblique surface, forces the lever arrangement out of the over-center position, in particular to above one Dead center position of the lever arrangement addition. This means that the force not only causes a displacement of the locking bar in its locking position, but at the same time a displacement of the holding part from the second position, in particular up to the first position.
Consequently, when the locking bolt reaches its locking position, the retaining part preferably simultaneously reaches its first position. Accordingly, the drive element is no longer fixed with respect to the holding part below. With such an embodiment of the locking device and the building closure drive is thus achieved that at the same time the locking of the building closure and a decoupling of the building closure drive from the wing done with a closing of the building closure using the building closure drive. As already explained above, it can also be provided to decouple the building closure drive from the wing by manually displacing the locking bolt into its locking position.
In a further embodiment of the invention can be provided that the transmission member extends in regions through the lock block. The closing block can serve as a guide for the transmission element, in particular the chain. For example, a guide in the lateral direction is achieved in this way. For example, the lock block has a plurality of inclined surfaces, in particular two inclined surfaces. The transmission member is now - at least when the building closure - between these inclined surfaces arranged. Additionally or alternatively, it may be provided the locking block has a recess for a region of the transmission member.

Finally, a handle for manual actuation of the locking device may be provided. This has already been indicated at the beginning. Therefore, the building closure can not be opened or closed exclusively by means of the mechanical building closure drive, but additionally by using the handle. The handle is preferably attached to the wing. Accordingly, it preferably serves not only for manual actuation, ie for unlocking or locking the building closure, but at the same time for applying a force to the wing by the user. With the aid of the handle, the building closure can thus be opened completely independently of the mechanical building closure drive.

The invention is further directed to a building closure with a frame, a wing and an actuating arrangement, the latter can be carried out according to the above embodiments.

The advantages of such a configuration of the building closure or actuating arrangement have already been pointed out. Both the building closure and the actuating arrangement can be developed in accordance with the above statements, so that reference is made to this extent.

The building closure can be configured, for example, as a window, preferably as a facade window or roof window, in particular as a living roof window, or as a dome light, as a dark flap, as an emergency exit or as a door.

In particular, the invention may be directed to a roof window, in particular a living roof window, with a locking device having at least one locking latch, which sets in a locking position a sash of the roof window with respect to a window frame in a closed position and releases in a release position for opening the roof window , It is envisaged that a mechanical roof window drive has a mounted on the frame drive element and the wing frame associated holding part, wherein the drive element is released in a first position of the holding part and fixed in a second position relative to the holding part, wherein the holding part in such a way with the locking bolt is operatively connected, that in the first position of the holding part of the locking latch is in its locking position and in the second position of the holding part in its release position.

The building closure is in this respect as a roof window, which has a building closure drive - here referred to as roof window drive - has. The roof window may be formed or developed according to the present description.

The FIG. 1 shows a building closure 1 in the form of a roof window, in particular a residential roof window. Of course, the building closure 1, however, any other configuration have and, for example, as a door or window of a general nature. The building closure 1 has a frame 2 and a wing 3 movably mounted relative to the frame 2. The wing 3 carries - in particular if the building closure 1 is present as a window or skylight - a glazing 4 of the building closure 1. The frame 2 is preferably fixedly mounted or 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 fastening element 5 is preferably screwed or screwed to both the frame 2 and the roof.

The frame 2 consists for example of several spars, namely a lower horizontal spar 6, an upper horizontal spar 7, a left vertical spar 8 and a right vertical spar 9. Analogously, the wing 3 preferably consists of a plurality of spars, which are not shown in detail here. The frame 2 and / or the wing 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 adversely affect the building closure 1.

As cover element, for example, one or more of the following elements may be present: An upper wing cover plate 10, a water apron 11, upper Flügelseitenabdeckbleche 12, lower Flügelseitenabdeckbleche 13 and side cover frame plates 14. The cover frame plates 14 close in side 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 building closure 1 according to the foregoing 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 building closure 1. The cover frame 21 or the cover elements 17, 18, 19 and 20 serve to discharge water from the building closure 1 in the direction of an environment, in particular of the roof. For this purpose, the covering element 17 has, for example, a cover skirt 22 which can be adapted to a shape or a structure of the roof. It becomes clear that the building closure 1, in particular the wing 3, has a handle or pivoting handle 23, which serves to actuate the building closure 1.

The FIG. 3 shows a portion of the building closure 1, in particular a part of an actuator, which has a locking device 24 with at least one locking latch 25. In the embodiment shown here two locking latch 25 are provided. In the following, only one of the locking latch 25 will always be described, but the embodiments are analogously applicable to the other. The closure bolt 25 is arranged, for example, in a guide recess 26. He is movably mounted on the wing 3 and can in particular in a locking position (shown here) and a release position can be arranged.

In the locking position of the locking bolt 25 cooperates with a lock block 27, not shown here, to lock the building closure 1 and consequently to fix the wing 3 in its closed position. Thus, if the wing 3 is in the closed position and subsequently the locking latch 25 is brought into the locking position, then the wing 3 can no longer be displaced out of the closed position, for example in the direction of an open position. Only when the locking bolt 25 is brought back into the release position, the wing 3 is released to open the building closure 1.

The building closure 1 or the actuating device also has a mechanical building closure drive 28. This has a drive element 29 mounted on the frame 2. The bearing of the drive element 29 on the frame 2 is preferably realized by means of a transfer member 30, not shown here, which is formed for example as a chain. The building shutter drive 28 further has a holding part 31 and a displacement element 32, which is designed for example as a displacement housing.

The holding member 31 is movably mounted with respect to the wing 3 and thereby in a first position (shown here) and a second position can be arranged. The holding part 31 has at least one rear grip element 33, in the exemplary embodiment shown here, two rear grip elements 33. Hereinafter, only one the rear grip elements 33 received, but the versions are readily transferable to each other. The rear grip element 33 is mounted, for example, by means of a pin 34 on the holding part 31. The rear grip element 33 is formed, for example circular-cylindrical and mounted on the holding part 31, in particular mounted eccentrically. However, other types of storage can be realized.

It can be seen that the drive element 29 has a rear engagement recess 35 corresponding to the engagement element 33, in particular in each case a rear engagement recess 35 for each of the engagement elements 33. The engagement recesses 35 are arranged on opposite sides of the drive element 29.

The holding part 31 is mounted on the wing 3 in such a way that in its first position the catch elements 33 do not come into contact with the displacement element 32. In particular, the holding part 31 is arranged in its first position largely or even completely outside of the displacement element 32. However, it may alternatively be provided that the catch elements 33 abut against the displacement element 32. However, care should be taken to ensure that this concern is such that when the holding part 31 is arranged in its first position, the rear grip elements 33 are present outside the rear grip recesses 35 or are not forced into them. In the second position of the holding part 31, however, the rear grip element 33 should cooperate with the displacement element 32 and be urged by this in the direction of the drive element 29 and its rear handle recess 35. Is there, which is not shown here the drive element 29 is arranged in the holding part 31, the rear grip element 33 engages in the corresponding rear engagement recess 35, so that subsequently the drive element 29 is fixed relative to the holding part 31.

Furthermore, it is now provided that the holding part 31 is operatively connected to the closure latch 25, so that a displacement of the holding part 31 also causes a displacement of the closure bar 25 and vice versa. In the first position of the holding member 31 while the locking latch 25 is present in its locking position and in the second position in its release position.

In the state of the building closure 1 shown here, the drive element 29 is arranged at a distance from the holding part 31. Accordingly, a contact surface 36, which is provided on the drive element 29, spaced from a counter-bearing surface 37, which is provided on the holding part 31 and the wing 3. As already explained above, the building closure 1 has the pivoting handle 23. This is used for manual actuation of the locking device 24 and the actuation of the building closure 1, wherein the actuation in particular an unlocking and locking in the case of the locking device 24 and an opening and closing in the case of the building closure 1 is understood.

The FIG. 4 shows a region of the building closure 1, wherein in particular a part of the building closure drive 28 with the drive element 29 and the closing block 27 can be seen. Other elements have not been shown for clarity. It is clear that the closing block 27 at least one Sloping surface 38, in particular a plurality of inclined surfaces 38 has. The inclined surface 38 occurs in a closing of the building closure 1 in touching contact with the present in its release position locking latch 25 and urges it in the direction of its locking position or into it.

The inclined surface 38 is designed such that when fully closing the building closure 1, so when reaching the closed position by the wing 3, the locking bar 25 reaches its locking position. After the building closure 1 has thus been completely closed, it is automatically additionally locked and subsequently can not be opened without further user interaction.

The FIG. 5 shows a further view of a portion of the locking device 24 and the building closure actuator 28. In this view, it can be clearly seen that the means of the pins 34 but preferably not necessarily eccentrically mounted rear grip element 33 upon insertion of the holding member 31 in the displacement element 32 of the latter inwardly is urged. If the drive element 29 is already present in the holding part 31, then the rear grip element 33 engages in this or in the rear grip recess 35, so that subsequently the drive element 29 is fixed relative to the holding part 31. The holding part 31 is operatively connected via a lever arrangement 39 (not shown here) to the closure bar 25 or to both closure bars 25.

The FIG. 6 shows a detailed view of the holding part 31 with the mounted thereon at least one rear grip element 33. The rear grip elements 33 are stored for example between two bearing plates 40 and 41. The bearing plate 40 is located on a base plate 42 (not shown here) of the locking device 24 displaced. In particular, the holding part 31 engages with a guide projection 43, the base plate 42, wherein on the bearing plate 40 opposite side of the guide projection 43, a guide plate 44 is arranged.

Preferably, both the bearing plate 40 and the guide plate 44 are applied to the base plate 42, in particular on opposite sides. In this way, a reliable storage or management of the holding member 31 is achieved on the wing 3. On the guide plate 44, for example, a force transmission element of the pivoting handle 23 attack, in particular on a projection 45th

The FIG. 7 shows a portion of the locking device 24 and the building closure drive 28. Of the latter, in particular, the holding part 31 is shown. More specifically, the guide plate 44 can be seen, on which, for example, the projection 45 is present. Only rudimentary the locking latch 25 can be seen. Here now clearly the lever assembly 39 can be seen, via which the holding member 31 is operatively connected to the locking latch 25. In the following, only one side of the lever arrangement 39, that is to say only one of the closure latches 25, will be discussed. However, the lever assembly 39 is preferably designed symmetrically.

The lever arrangement 39 comprises a connecting arm 46, which at a bearing point 47 on the holding part 31 and at a bearing 48th engages a Verschlussriegelarm 49, on which the locking latch 25 is arranged. The locking latch arm 49 is rotatably mounted on a bearing 50 with respect to the wing 3, in particular on the base plate 42. The holding part 31 is spring-loaded with a first spring element 51.

Additionally or alternatively, the connecting arm 46 is spring-loaded by means of a second spring element 52. The second spring element 52 engages, for example, on its side facing away from the connecting arm 46 at the bearing point 50. Preferably, both the spring element 51 and the spring element 52 are fixed on its side facing away from the holding part 31 or connecting arm 46 on the wing 3 and the base plate 42. In the illustration shown here, the holding part 31 is in its first position and correspondingly the locking latch 25 in its locking position.

The FIG. 8 shows the above with reference to the FIG. 7 arrangement described again, but now the holding part 31 is present in its second position and corresponding to the locking latch 25 in its release position. It will be appreciated that the bearings 47, 48 and 50 are located in an over-center position. Accordingly, by applying force to the holding part 31 this no longer back to its first position - which is based on the FIG. 7 was described - returned. Such a displacement of the holding member 31 is rather only by a displacement of the shutter bolt 25 (not visible here) to accomplish.

The FIG. 9 shows a portion of the building closure 1 during opening. It is clearly evident that the drive element 29 is urged by means of the transmission member 30 in the direction of the wing 3 and in the direction of its open position. Accordingly, a driving force is impressed on the wing 3, which displaces it in the direction of its open position. The drive element 29 is thereby fixed as long as on or in the holding part 31 until the building closure 1 is closed again by means of the building closure drive 28. Only with this closing the locking bar 25 is subjected to the force of the inclined surface 38 so that it is moved back into its locking position.

Due to the lever arrangement 39, this simultaneously ensures a displacement of the holding part 31 back into its first position, in which, however, the drive element 29 is no longer fixed relative to the holding part 31. Accordingly, after closing the building closure 1 by means of the building closure drive 28, the drive element 29 or the building closure drive 28 is again completely decoupled from the wing 3. Before or when opening the building closure 1 by means of the pivoting handle 23, therefore, no such decoupling must be made manually. This facilitates the operation of the building closure 1 considerably.

The FIG. 10 shows a detailed representation of a portion of the building closure drive 28, wherein in particular the drive element 29, the holding part 31 and the displacement element 32 are shown. It can be clearly seen that the rear grip element 33 has a recess 53 whose dimensions are seen in cross-section with respect to a longitudinal center axis of the pin 34 greater than dimensions of the pin 34. In that regard, the inner diameter the recess 53 is greater than an outer diameter of the pin 34. The rear grip element 33 is so far in the embodiment shown here as a hollow cylinder before, which is movably mounted relative to the holding part 31 by means of the pin 34. The pin 34 is preferably arranged or fixed rigidly on the holding part 31.

The pin 34 passes through the recess 53 for the realization of a guide or storage of the rear grip element 33. It is now not, as described above, a continuous eccentric mounting of the rear grip element 33 with respect to the holding part 31 before. Rather, only the guide is provided by means disposed in the recess 53 pin 34. Of course, the storage shown here or the configuration of the rear grip element 33 with the recess 53 can be applied to the above-described building closure 1 or the actuating arrangement.

The FIG. 11 again shows a portion of the building closure drive 28, wherein a further possible embodiment for the storage of the rear grip element 33 is shown on the holding part 31. Thus, the pin 34 is rigidly connected to the rear grip element 33. Preferably, the pin 34 is located centrally on the rear grip element 33, but may also be provided an eccentric arrangement. The pin 34 engages in at least one guide recess 54, which is configured in the present embodiment as a slot. The guide recess is aligned such that a displacement of the pin 34 in the lateral direction, in particular with respect to a longitudinal center axis of the holding part 31, is allowed while a displacement in the axial direction is inhibited.

Preferably, on both sides of the rear grip element 33, in each case such a guide recess 54 is formed in the holding part 31, so that a stable and reliable guidance of the rear grip element 33 is realized. With regard to the further embodiment of the building closure drive 28 and the building closure 1, reference is made to the other embodiments. The configuration of the rear grip element 33 or of the holding part 31 with the at least one guide recess 54 shown here can of course also be applied to the building closure drive 28 or the building closure 1 according to the other embodiments.

The FIG. 12 shows a third embodiment of the building closure drive 28. In contrast to the embodiments described above, the drive element 29, the form-fitting recess, while the holding member 31 is formed as a positive locking element and insofar has the Hintergriffsausnehmungen 35. Accordingly, the at least one rear grip element 33 is mounted on the drive element 29, wherein the pin 34 is provided.

The storage takes place analogously to the procedure described with reference to the first embodiment. This means that the rear grip element 33 has the recess 53, which is penetrated by the pin 34. The pin 34 is rigidly secured to the drive member 29. With regard to the further embodiment of the building closure drive 28, reference is made to the further embodiments. The embodiment shown here can of course be applied to the building closure drive 28 and the building closure 1 according to the above statements.

The FIG. 13 shows a fourth embodiment, which is basically similar to the third embodiment described above, so reference is made to the corresponding embodiments. The difference lies only in the mounting of the rear grip element 33 on the drive element 29. This is analogous to the second embodiment also described above, so that the drive element 29 has the at least one guide recess 54, which is present for example in the form of the slot. By contrast, the rear grip element 33 has the pin 34 fixed rigidly to it, wherein the attachment is preferably provided centrally on the rear grip element 33.

With regard to the further embodiment of the building closure drive 28 or the building closure 1, reference is made to the above statements. This embodiment can also be applied to the building closure drive 28 or the building closure 1 according to the above statements.

Based on FIGS. 14 to 16 the mode of operation or the interaction of drive element 29, holding part 31 and displacement element 32 is explained in more detail, this being done on the basis of the fourth embodiment described above. However, the embodiments are readily applicable to the other embodiments.

The FIG. 14 shows the elements of the building closure drive 28 in a first state. In this case, the drive element 29 is already so far on the holding part 31 or the displacement element 32 to be displaced that the holding part 31 engages in the drive element 29 and the form-fitting recess. The rear grip element 33 or the rear grip elements 33 are, for example, still in a direction away from the holding part 31 in the radial direction as far as possible, so that the respective corresponding pin 34 is present at a side facing away from the holding part 31 edge of the guide recess 34.

In the FIG. 15 It can be seen how the drive element 29 is further displaced in the direction of the holding part 31 and the displacement element 32, so that a second state is present. In this, the holding part 31 has already been displaced by the drive element 29 in the direction of the displacement element 32, so that it is so far shifted from its first position in the direction of its second position and thereby exists between them. It can be clearly seen that the at least one rear grip element 33 comes into touching contact with the displacement element 32, so that it is urged in the lateral direction onto the holding part 31 and into the corresponding rear grip recess 35.

If the drive element 29 is further displaced in the direction of the holding part 31 or the displacement element 32, as shown in the FIG. 16 is shown for a third state, the holding part 31 comes to its second position. In this, the at least one rear engagement element 33 is completely displaced in the direction of the holding part 31, so that it completely engages in the respective rear engagement recess 35. The drive element 29 can not be solved more of the holding part 31, as long as this is in its second position.
The FIG. 17 shows the building closure drive 28 in another embodiment not belonging to the invention. Shown is in particular a region of the sash 3 with the locking device 24. It can be seen the holding part 31, which is present here in its first position. As already explained above, the holding part is operatively connected to the at least one locking latch 25 in such a way that the locking latch 25 is in its locking position in the first position of the holding part 31 and in its release position in the second position of the holding part 31. Basically, reference is made to the above statements, which can be used as meaningful supplementary.
The holding part 31 has in the embodiment shown here a retaining projection 55, which is in the form of a retaining rib. The holding projection 55 has a longitudinal central axis in the direction of its greatest extent, which is preferably perpendicular to a direction of displacement of the holding part 31 between its first position and its second position or vice versa. By holding projection 55, the holding member 31 is formed as a positive connection element.
In contrast to the preceding embodiments, at least one guide element 56 is provided instead of the displacement element 32, which may preferably be present as a spring element. In addition to the elastic guide element 56, at least one further guide element 57 (here: two guide elements 57) may be provided, which is designed to be rigid. The guide element 56 and / or the guide member 57 have on their holding part 31 facing sides on a free end 58 and a free end 59 on. The free end 58 and / or the free end 59 preferably protrude in the direction away from the holding part 31 direction, ie extend away from the holding part 31, preferably to form a ramp 60 or 61 for the drive element 29 (not shown here).
The FIG. 18 shows the roof window drive 28 in the from FIG. 17 known not belonging to the invention embodiment in another view. The holding part 31 is further arranged in the first position. It can be clearly seen that, in the first position, the holding part 31 is arranged such that the guide element 56 at least partially overlaps the holding projection 55. In particular, the retaining projection 55 is located at a vertical plan view under the ramp 30. This may additionally and / or alternatively for the at least one guide member 57 and its run-on slope 61 apply. Preferably, however, the guide member 55 extends further in the direction of the holding member 31 as the guide member 57, wherein in particular the guide member 57 in the presence of the holding member 31 in its first position, the retaining projection 55 does not overlap and is so far spaced from him.
It is also clear that the guide member 57 is formed on a first receiving element 62, while the guide member 65 is disposed on a second receiving element 63 which is attached to the first receiving element 62, in particular clipped on this is. The first receiving element 63 is preferably attached directly to the base plate 42 of the previous device 24. Of the first receiving element 62 may also a guide arm 64 extending, which extends parallel to the displacement direction of the holding part 31. The guide arm 64 may be configured such that in the first position of the holding part 31 it protrudes at least as far as the holding projection 55, in particular overhanging it. The guide arm 64 serves to guide the drive element 29.
The FIG. 19 shows a further portion of the roof window drive 28 according to the further not belonging to the invention embodiment. In particular, the drive element 29 is shown. It can be seen that the drive element 29 has a form-fitting recess 65, which is preferably present as a groove in the drive element 29. A longitudinal center axis of the positive engagement recess 65, which extends in the direction of the largest extension of the positive engagement recess 65, is perpendicular to a displacement direction of the drive element 29, which by the double arrow 66 is indicated. Additionally or alternatively, the longitudinal center axis of the form-fitting recess 65 or the form-fitting recess 65 itself projects parallel to the retaining projection 55 or its longitudinal central axis.
The positive engagement recess 65 is provided for receiving the drive element 29, in particular of the holding projection 55. In particular, the form-fitting recess 65 is adapted to the retaining projection 55 for this purpose. Furthermore, the drive element 29 has a run-on slope 67, which preferably connects directly to the positive-engagement recess 65. The ramp 67 rises in the direction of the form-fitting recess 65.

The form-fitting recess 65 is preferably delimited by a groove base 68 and opposite groove walls 69 and 70, which adjoin the groove base 68 in each case. The groove wall 70 extends, for example, further in the direction away from the groove bottom 68 as the groove wall 69. The groove walls 69 and 70 are preferably seen in cross-section with respect to the longitudinal center axis of the form-fitting recess 65. In this case, they are particularly preferably designed in such a way that they proceed steadily farther away from one another, starting from the groove bottom 68, so that straight lines lying in the groove walls 69 and 70 are in the form of a V-shape, which opens in the direction away from the groove base 68. Of course, the groove walls 69 and 70, however, may also be arranged parallel to one another.

The groove wall 69 or the web lying between the form-fitting recess 65 and the bevel 67 now forms the rear grip element 33. This is designed to engage behind the retaining part 31 or its retaining projection 55 at least in the second position of the retaining part 31. The groove wall 70, however, forms the contact surface 36 which comes into contact with the counter-abutment surface 37 of the holding member 31 in a displacement of the drive member 29 in the direction of the holding member 31 so that the drive member 29, the holding member 31 in its second position and / or the wing 3 in Direction of the open position urges. The counter abutment surface 37 is preferably present on the holding projection 55.

In the illustration shown here, it can be seen that the run-on bevel 67 can face another run-on slope 71. This ramp 71 acts on a displacement of the drive member 29 in the direction of the holding member 31 with the ramp 30 and / or the ramp 30 so that the drive member 29 is pushed in the direction of the holding member 31 and thus the holding projection 55 into the form-fitting recess 65.

If the drive element 29 is displaced in the direction of the holding part 31, it is now initially provided that the run-on slope 67 facilitates driving over the holding projection 55 by the drive element 29, in particular the rear grip element 33. With the aid of the run-up bevel 67, the drive element 29 can thus be reliably arranged such that the holding projection 55 of the holding part 31 is present above or in the positive-fit recess 65.

While the ramp be 67 can come into touching contact with the retaining projection 55, whereby the drive element 29 is urged away from the holding part 31, the ramp be 71 comes into contact with the guide element 56, which is preferably elastic. Accordingly, the guide member 56 is elastically deflected when the drive member 29 is further displaced in the direction of the holding member 31.

If the run-on bevel 67 has passed the holding projection 55, so that the holding projection 55 is present in the region of the positive-fit recess 65, the guide element 56 forces the drive element 29 in the direction of the holding part 31 due to its elastic deflection or the resulting spring force, so that the holding projection 55 in the following Formschlussausnehmung 65 is arranged. The groove wall 70 and the abutment surface 36 now abuts against the abutment surface 37. In a further displacement of the drive element 29 in the direction of the holding part 31 this is so far shifted in the direction of its second position.

Based on FIG. 20 the above-described further not belonging to the invention embodiment of the roof window drive 26 is shown again in the assembly. The holding part 31 is present in its first position, while the holding projection 55 engages in the form-fitting recess 65 of the drive element 29. The guide element 56 urges the drive element 29 in the direction of the holding part 31, so that the retaining projection 55 can be deployed only by appropriate effort from the positive engagement recess 65. At the same time, the abutment surface 36 bears against the abutment surface 37. In a further displacement of the drive element 29 in the direction of the holding part 31, the holding part 31 is displaced from the first position shown here to its second position.
In the second position, the drive element 29 is held by the guide member 56 and / or the guide member 57 such that the retaining projection 55 can not get out of the positive engagement recess 65, preferably independent of the force applied to the drive member 29 force. Only after a shift from the second position to the first position of the drive element 29, the retaining projection 55 can get back out of the positive engagement recess 65, in particular the drive element 29 deflects the guide member 65 against its spring action. Subsequently, the drive element 29 with respect to the holding part 31 is released again.

Overall, with the above-described actuation assembly for the building closure 1 an elegant way created to be able to operate the building closure 1 both by means of the mechanical building closure actuator 28 and manually by hand, without manually establish or release the connection between the drive member 29 and the holding member 31 have to. The operation of the building closure 1 is consequently considerably simplified by the actuating arrangement.
