Description

The invention relates to a flap device of a building according to the preamble of claim 1.

Such a flap device comprises a frame delimiting an opening and a hinged wing which can be pivoted to the frame. The folding wing is approximated in a closed position to the frame for closing the opening and can be pivoted out of the closed position for at least partially releasing the opening. In addition, a motor drive device for pivoting the folding wing is provided relative to the frame. The drive device comprises a housing and a push rod extending along a longitudinal axis and adjustable relative to the housing along the longitudinal axis. The push rod is hinged to the one of the frame and the folding wing and the housing to the other of the frame and folding wings, and by adjusting the push rod to the housing, the folding wing can be pivoted relative to the frame.

At one of the DE 102 13 427 A1 known device for pivoting a window sash relative to a window frame is provided on the frame a spindle with a spindle nut arranged thereon. The spindle can be rotated, driven by a drive motor, so that the spindle nut rolls on the spindle and is moved longitudinally along the spindle. About a linkage, the spindle nut is coupled to the window wing to be pivoted, so that can be moved by adjusting the spindle nut of the window sash.

For example, spindle drives for moving a tailgate of a vehicle are known from automotive engineering. For example, from the DE 20 2008 008 118 U1 Known drive assembly is a spindle drive with a housing on the one hand articulated on a vehicle body and with a housing adjustable to the push rod on the other hand on a tailgate. By adjusting the push rod relative to the housing along a longitudinal axis, which is predetermined by a spindle enclosed in the housing, the tailgate can be pivoted relative to the vehicle body.

A similar drive arrangement is also from the WO 2013/045099 A1 known. Both the content of DE 20 2008 008 118 U1 as well as the content of WO 2013/045099 A1 should be fully included in the present application.

In the case of flap devices of a building, in particular in the case of so-called flap-wing windows, in which a folding wing is mounted about a horizontally directed pivot axis for releasing e.g. a roof opening can be pivoted, is nowadays regularly on a horizontal lower edge of an actuator, such as an operating handle, provided for the manual operation of a locking device for locking and unlocking the folding wing. This requires that a user for a free access to the folding wing and on the other hand, the folding wing - especially when used on a skylight - can even reach. The actuator must be in an area that is easily accessible to a user.

It follows that often the installation position of a roof window is not readily selectable. In addition, the operation of an actuator may require a considerable amount of force, which is all the more disadvantageous if the actuator is not accessible to a user in a comfortable manner.

In addition, comparatively large forces are required regularly to move a folding wing in a roof window, which can also change with the opening angle of the folding wing. Although nowadays such spring windows or damping devices using gas springs are used on such manually operated roof windows, which should support a moving a folding wing. However, such devices can not completely compensate for the forces arising, for example, solely by the weight of a folding wing. On the other hand, different mechanisms with different spring strengths may be required depending on the roof pitch with different roof windows, so that resulting forces are compensated in a sufficient manner.

There is a need for flap devices for buildings that are comfortable for a user to use and on the one hand allow easy operation of a Verrieglungseinrichtung and on the other hand, a comfortable adjustment of a folding wing.

The present invention has for its object to provide a flap device of a building available, which allows a comfortable operation for a user.

This object is achieved by an article having the features of claim 1.

Accordingly, a locking device is provided for locking the folding wing with the frame in the closed position, wherein the drive device is formed, upon actuation for pivoting the folding wing from the closed position to operate out the locking device for unlocking the folding wing of the frame.

The present invention initially starts from the idea to use a motor drive device in a flap device of a building, which allows adjustment of the folding wing relative to the frame by adjusting a push rod along a longitudinal axis relative to a housing. The motorized drive device can be used to adjust the folding leaf in a driven manner so that a user merely operates the drive device, but does not have to act manually on the folding leaf. The pivoting of the folding wing thus takes place in a motor-driven manner.

By means of the locking device in this case also a locking of the folding wing is provided with the frame in the closed position, so that the folding wing is not held solely on the transmission of the drive device in its closed position, but is mechanically locked in the closed position via the locking device with the frame.

In a specific embodiment, a locking element is arranged on the push rod, which engages in the closed position in an engagement member on the frame or the folding wing for locking the folding wing with the frame and can be brought by adjusting the push rod relative to the housing out of engagement with the engagement element.

The Verrieglungselement engages in the closed position preferably positively in the (for example, arranged on the frame) engaging element and thus provides a firm connection between the folding wing and the frame ago, so that, without operating the drive device, the folding wing not or at least not readily can be opened. If the drive device is actuated for opening the folding wing, the push rod is moved relative to the housing and thereby also displaces the push rod relative to the engagement element, so that the locking element arranged on the push rod is likewise adjusted to the engagement element and brought out of engagement with the engagement element ,

The unlocking of the flap device is thus carried out automatically upon actuation of the drive device for opening the folding wing. Further actuation of a further locking device is not required.

The fact that the locking device is actuated automatically in cooperation with the drive device when opening or closing the folding wing, results in a generally simple structure, which can still provide a secure and reliable locking in the closed position. The structure can be realized inexpensively using only a few components and allows easy operation.

The drive device can be controlled, for example, by a user by means of a remote control for opening or closing the folding leaf. It is also conceivable that the drive device interacts with a control device, wherein the control device can effect, for example, depending on suitable sensor signals, an automatic opening or closing of the flap device.

Characterized in that the locking device is actuated by the drive device, an access of a user to the flap device for actuating is no longer directly required. This makes it possible to arrange the flap device, in particular when using a roof window, as desired, regardless of the accessibility by a user. The fact that the flap device can be operated completely by motor results in increased comfort for a user. For example, several flap devices can be operated simultaneously. The operation can be done alone via a remote control, a suitable switch or the like. Likewise, a completely automatic operation, for example, in cooperation with a control device and a sensor, such as a rain sensor or the like, possible.

The drive device may be self-locking, but this need not. If the drive device, for example in the form of a spindle drive, is not designed to be self-locking, then the folding leaf can also be moved manually by a user.

In order to enable a user, for example, in a power failure, unlocking the folding wing, may also be provided a suitable Entriegelungsgestänge, by means of which the push rod attached to the locking element can be brought out of engagement with the engagement element, for example by the engagement member is moved to the frame.

The push rod is hinged to the frame or the folding wing. The housing is then hinged to the respective other component, ie to the folding wing or the frame, so that the drive device extends between the folding wing and the frame.

In an advantageous embodiment, the housing may be articulated to the frame and the push rod, for example, hingedly connected to the folding wing. In the closed position, arranged on the push rod locking element engages in the arranged on the frame engagement element and provides an interlocking connection between the folding wing and the frame forth, so that opening the folding wing from its closed position out not readily, at least not without unlocking the engagement between the locking element and the engagement element, is possible.

The push rod may, for example, be hinged to a retaining portion of the folding wing (when the push rod is hinged to the folding wing) or the frame (when the push rod is hinged to the frame). About the holding portion, the push rod is thus pivotally connected to the respectively associated component, wherein the articulated connection is configured such that a change in position of the push rod can be compensated relative to the associated component in an adjustment of the folding wing.

In this case, it is preferably provided that the push rod can be adjusted relative to the holding section via a predetermined adjustment path, also referred to as idle stroke. The articulated connection of the push rod with the holding portion is thus such that at least over a certain adjustment a relative movement of the push rod relative to the holding portion is possible. This displacement is maintained to allow movement of the push rod relative to the engagement member in the closed position of the flap means to effect locking and unlocking of the flap means in this manner.

Thus, while the folding wing is in the closed position, the push rod can be moved from a position in which the locking element is lockingly engaged on the push rod with the engagement element without the folding wing already being moved. By this relative movement unlocking, ie a disengagement of the locking element with the engagement element is possible. After unlocking the folding wing can then be taken and thus moved to open the flap device. Conversely, when the flap device is closed when the folding wing is already closed, the push rod with the locking element arranged therein can still be moved over a certain adjustment path relative to the engagement element in order to lock the flap device.

Between the push rod and the holding portion preferably acts at least one spring element, which serves for providing a biasing force between the holding portion and the push rod. By means of such a spring element can be ensured in particular that when locking the locking element can in turn be brought into engagement with the engagement member.

The articulated connection of the push rod to the holding section can be produced, for example, via a rod element extended along the longitudinal axis of the drive device. The rod element passes through the holding portion, for example, at a bearing opening of the holding portion, which is shaped so that the rod member can be pivoted relative to the holding portion at least over a certain angular range and thereby provides an articulated connection of the push rod to the holding portion.

Preferably, a spring element for providing a prestressing force between the holding portion and the push rod is arranged on the rod element on both sides of the holding portion. A first spring element is thus arranged on the rod element between the holding portion and the push rod. A second spring element is located on the rod element on a side facing away from the push rod of the holding portion and acts for example between the holding portion and a head of the rod member. By means of the two spring elements on both sides of the holding portion, a two-sided elastic bias of the rod member is thus provided relative to the holding portion.

In an alternative embodiment, the drive device may also be designed to act upon actuation for pivoting the folding leaf on an actuating linkage of the locking device for actuating the locking device. This is based on the idea to use a locking device, as it is conventionally present for example in a manually operable window. Such a locking device has an actuating linkage, for example in the form of a shear-resistant band, which extends for example on the folding wing and along an actuating direction on the folding wing is displaceable. For example, the actuating linkage extends at least in sections around the folding wing and carries locking elements that can be brought into or out of engagement with engagement elements on the frame, thereby locking or unlocking the folding wing with the frame. For the purposes of the present invention, the drive device acts on the actuating linkage of the locking device to unlock the locking device when opening the folding wing and vice versa when closing the folding wing, the locking device to lock again. As a result, when opening, for example, a plurality of locking elements in the form of locking pins on the actuating linkage can be brought out of engagement with engagement elements in the form of closing pieces on the frame. Conversely, for locking when closing the folding wing, the locking elements can in turn be brought into engagement with the engagement elements.

For cooperation with the actuating linkage, the push rod can engage, for example via a suitable, coupled to the push rod actuating portion in a slot of the actuating linkage, so that the push rod is movable at least by a predetermined displacement relative to the actuating linkage. The push rod is thus on the one hand relative to the holding portion over which the push rod is preferably fixed to the folding wing, and on the other hand to the actuating linkage by a certain adjustment adjustable, the respective adjustment paths are advantageously different and coordinated so that the locking device when opening unlocked the folding wing and in turn can be locked when closing the folding wing.

The folding wing is preferably pivotable about a pivot axis relative to the frame, which extends in a roof window, for example, in the horizontal direction and thus allows pivoting of the folding wing in a direction perpendicular to the pivot axis pivot plane. The drive device is in this case articulated on the one hand on a frame section of the frame extending transversely to the pivot axis and on the other hand on a wing section of the folding wing which extends transversely to the pivot axis and extends in a plane which is directed substantially perpendicular to the pivot axis and thus runs parallel to the pivot plane.

In principle, it is possible to provide only one drive device on one side of the folding wing or centrally on the folding wing. It is also conceivable and possible, however, to provide two drive devices on both sides of the folding wing or even more than two drive devices.

The drive device is preferably formed by a spindle drive with a spindle extending along the longitudinal axis and a spindle nut arranged on the spindle and adjustable relative to the spindle along the longitudinal axis. The spindle provides the longitudinal axis of the drive device and is in threaded engagement with the spindle nut. Characterized in that the spindle nut rolls on the spindle, the spindle nut can be adjusted along the longitudinal axis relative to the spindle to move in this way the housing relative to the push rod and thus to adjust the drive device.

Basically, it should be noted that other drive devices can be used as spindle drives. For example, other push rod drives can be used.

In a specific embodiment, for example, a spindle drive can be used, as he, for example, from the DE 20 2008 008 118 U1 or the WO 2013/045099 A1 the content of which is to be fully included in the present text. Such a spindle drive may for example also have a wrap spring brake device for braking output side adjacent forces. About such a spring brake device can be supported on the output side via the folding wing in the drive device forces, for example, the weight of the folding wing, supported.

In an advantageous embodiment of a spindle drive, the spindle can be rotatably arranged on the housing of the spindle drive and are in operative connection with an electric motor for driving the spindle. The spindle nut is in this case non-rotatably arranged on the displaceable on the housing mounted push rod such that during a rotational movement of the spindle, the spindle nut is displaced together with the push rod along the longitudinal axis relative to the housing. By rotating the spindle, driven by the electric motor, thus rolling the spindle nut (which is rotatably mounted on the tube of the push rod) on the spindle, so that due to a threaded engagement of the spindle nut with the spindle, the spindle nut along the longitudinal axis, along which the Spindle extends, adjusted relative to the spindle and thus the push rod is moved relative to the spindle.

The electric motor can be arranged coaxially to the spindle in the housing, so that a slim, along the longitudinal axis extending design of the spindle drive results in low space requirements.

The push rod is advantageously biased by a spring relative to the housing. For example, the spring may bias the push rod toward an extended position in which the push rod is extended out of the housing on which the spindle is located. For example, acts a weight of the folding wing in the direction of retraction on the push rod, so this weight can be compensated by the biasing spring, so that the folding wing can be safely supported and held over the spindle drive.

Act no appreciable weight forces around the pivot axis on the folding wing and a bias in a particular position of the flap is not desirable, so can be dispensed with the biasing spring.

The idea underlying the invention will be explained in more detail with reference to the embodiments illustrated in the figures. Show it:

1 shows a schematic view of a flap device 1 with a frame 10 and one on the frame 10 about a horizontally extending pivot axis S pivotally arranged folding wings 11 , The frame 10 limits an opening 2 and carries over a horizontally extending frame section 100 the folding wing 11 that has a wing section 110 articulated with the frame section 100 of the frame 10 connected is.

Between transversely to the pivot axis S extended, lateral wing sections 111 . 112 of the folding wing 11 between which a windowpane 113 is bordered, and transverse to the pivot axis S extended, side frame sections 101 . 102 of the frame 10 extend two drive devices 3 used for motorized adjustment of the folding wing 11 relative to the frame 10 serve. So is the folding wing 11 in a closed position the frame 10 approximates and closes the through the frame 10 limited (window) opening 2 , From the closed position out of the folding wing 11 be moved in an opening direction A, in this way the flap means 1 to open.

The drive devices 3 are preferably designed as spindle drives, as described below with reference to FIG 3A . 3B and 4 yet to be explained. However, it should be noted at this point that in principle also other types of drives, for example, hydraulic or pneumatic drives or other push rod drives, are conceivable and possible. As such, the present invention is not limited to the use of spindle drives.

The drive devices 3 Show how 2A to 2C visible, in each case a housing 30 and one along a longitudinal axis L relative to the housing 30 adjustable push rod 31 on. In the illustrated embodiment, the housing 30 about a pivot axis S1 pivotally mounted on a bearing block 103 of the frame 10 hinged and thus articulated with the frame 10 connected. The push rod 31 however, is about a rod element 315 at least to some extent hinged to a holding section 114 of the folding wing 11 arranged and thus on the folding wing 11 hinged.

For pivoting the folding wing 11 about its pivot axis S, the housing 30 and the push rod 31 along the longitudinal axis L are moved relative to each other, wherein the opening of the folding wing 11 in the illustrated embodiment, the push rod 31 out of the case 30 extended, thereby the push rod 31 moved in an adjustment direction V1 and in this way the length of the drive device 3 is increased, thereby pivoting the folding wing 11 to effect in the opening direction A.

Every drive device 3 serves on the one hand for motorized adjustment of the folding wing. On the other hand, every drive device realizes 3 also a locking device 4 by pushing the push rod 31 a locking element 40 in the form of a hook or the like, in the closed position of the folding wing 11 in positive engagement with an engagement element 41 in the form of a hook or the like on the frame 10 stands, as in 2A is shown. In the closed position is the folding wing 11 thus with the frame 10 locked so that the folding wing 11 not without unlocking, so not without disengagement of the locking element 40 with the engagement element 41 , can be opened.

To unlock the folding grand piano 11 and to open the folding wing 11 becomes the driving device 3 operated and thereby the push rod 31 out of the case 30 extended, leaving the push rod 31 moved in the adjustment direction V1. Due to the coupling of the push rod 31 over the rod element 315 with the holding section 114 has the push rod 31 in this case a Leerhub opposite the holding section 114 on, which corresponds to a displacement H, beyond the push rod 31 when in the closed position located folding wings 11 initially opposite the holding section 114 can be adjusted without doing the folding wing 11 is taken. This adjustment H allows the push rod 31 relative to the frame 10 and the engagement element disposed thereon 41 in the adjustment direction V1 to move in this way, as shown in 2 B is shown, the locking element 40 out of engagement with the engagement element 41 bring to.

After reaching the in 2 B shown, unlocked position of the push rod 31 can the folding wing 11 in the opening direction A relative to the frame 10 be pivoted to this way the flap device 1 to open.

On the rod element 315 are two spring elements 37 . 38 arranged, of which the one spring element 37 between the push rod 31 and the holding section 114 and the other spring element 38 between the holding section 114 and a head 316 of the rod element 315 is arranged so that both sides of the holding section 114 one spring element each 37 . 38 on the rod element 315 is arranged. In the closed position according to 2A is that between the holding section 114 and the head 316 acting spring element 38 compressed along the longitudinal axis L and thus tensioned to pressure (possibly, the spring element 38 be pressed in the closed position on block). Will the push rod 31 for unlocking the flap device 1 moved in the adjustment direction V1, so relaxes the spring element 38 while the other spring element 37 in operative connection with the push rod 31 occurs and is stretched to pressure, as in 2 B is shown. About the spring element 37 that depends on the on the folding wing 11 acting forces may be clamped on block, thus an adjusting force in the holding section 114 and above in the folding wing 11 initiated to the folding wing 11 to open in the opening direction A.

To close the folding wing 11 the foregoing is reversed. This is how to adjust the folding grand piano 11 from an open position in the direction of the closed position (opposite to the opening direction A), the push rod 31 in the case 30 retracted, so that the push rod 31 moves in a direction of adjustment V1 opposite adjustment V2, as shown in 2C is shown. The drive device 3 gets back into position in this way 2 B in which the folding wing 11 the frame 10 approximated, but a lock is not (yet) made. By further moving the push rod 31 in the adjustment V2 then the locking element 40 in engagement with the engagement element 41 pulled and thus the flap device 1 locked, the spring element 38 is tense until the in 2A shown position is reached.

3A and 3B show a concrete embodiment of a drive device 3 in the form of a spindle drive. The drive device 3 has a spindle 32 on, which extends along a longitudinal axis L, rotatably on a housing 30 is arranged and with a gear 34 and an electric motor 35 communicates.

The spindle 32 has on its outer circumferential surface on an external thread, with an internal thread on a bore 313 a spindle nut 310 engaged. The spindle nut 310 is rotatably on an (inner) pipe of a push rod 31 held over one of the spindle nut 310 opposite end face 314 in a cladding tube 312 is stored. The cladding tube 312 is on the case 30 slidably mounted (but non-rotatable) along the longitudinal axis L, so that over the cladding tube 312 also the tube 311 on the housing 30 is guided.

At the front 314 the push rod 31 is a rod element 315 for coupling the push rod 31 with the holding section 114 of the frame 10 (see eg 2A ) arranged.

During operation of the drive device 3 the electric motor displaces 35 over the transmission 34 the spindle 32 in a rotational movement about the longitudinal axis L. Due to the threaded engagement of the spindle nut 310 with the spindle 32 and the fixed one Arrangement of the spindle nut 310 at the push rod 31 rolls the spindle nut 310 at the spindle 32 off, leaving the spindle nut 310 along the longitudinal axis L relative to the spindle 32 is adjusted and together with the spindle nut 310 the pipe 311 and the cladding tube 312 be moved and thus the entire push rod 31 is moved.

3A shows here the drive device 3 in an extended position, wherein the spindle nut 310 to a gearbox 34 opposite end of the spindle 32 procedure is. 3B whereas the drive device shows 3 in a retracted position, where the spindle nut 310 the transmission 34 facing the end of the spindle 32 is approximated.

The push rod 31 is about a spring 33 in the form of a compression spring against the housing 30 preloaded and to a support 36 on the housing 30 supported. The bias is carried out in the direction of the extended position (see 3A ), so the spring 33 at a retraction of the push rod 31 opposite to the adjustment direction V is stretched to pressure, as in 3B is shown.

By means of the spring 33 can, in particular in a non-self-locking design of the drive device 3 , on the folding wing 11 acting weight forces are balanced to open the flap device 1 to assist and / or the folding wing 11 to keep in an open position. On the folding wing 11 Acting forces can by a suitable, by means of the spring 33 provided preload can be compensated, so that it due to eg weight forces of the folding wing 11 not to an automatic adjustment of the folding wing 11 can come.

Optionally, on the spring 33 also be waived, especially if a bias in a certain starting position is not desired or if no (significant) weight forces on a folding grand piano 11 act, which must be compensated by a spring (as for example in a vertically directed pivot axis of the flap 11 the case would be).

Between the transmission 34 and the spindle 32 can also be a wrap spring according to the in the DE 20 2008 008 118 U1 or the WO 2013/045099 A1 be arranged type to a driven side on the push rod 31 lock applied power, one drive side via the electric motor 35 transferred power but transfer.

A modified embodiment of a drive device 3 in which no spring for biasing a push rod 31 opposite a housing 30 is provided shows 4 , In the modified embodiment, as in the embodiment according to FIG 3A and 3B , a spindle 32 rotatably mounted and stands with a gear 34 and an electric motor 35 engaged. During operation of the drive device 3 becomes the spindle 32 in a rotational movement such that one with an external thread of the spindle 32 engaged, a bore 313 having spindle nut 310 at the spindle 32 unrolls and along an adjustment V axially relative to the spindle 32 is moved.

With the spindle nut 310 is a pipe 311 coupled, on the front side 314 the rod element 315 for connection to the holding section 114 of the folding wing 11 (see, for example 2A ) is arranged.

The pipe 311 the push rod 31 is axially displaceable on the housing 30 stored, but not a spring against the housing 30 biased. Also, an outer cladding tube is not present, so that there is an overall simple structure.

The operation of the drive device is otherwise identical as based on 3A and 3B described, so that reference should be made to the preceding embodiments.

Both in the embodiment of the drive device 3 according to 3A and 3B as well as in the embodiment according to 4 is the case 30 over a tight with the case 30 Connected coupling point 300 on the bearing block 103 of the frame 11 hinged.

In another, in 5 illustrated embodiment of a flap device 1 is a folding wing 11 pivotable about a pivot axis S on a frame 10 arranged, wherein on the folding wing 11 an actuating linkage 42 is provided in the form of a circulating belt, which together with on the actuating linkage 42 arranged locking elements 40 and on the frame 10 arranged engagement elements 41 a locking device 4 realized, which also manually over a handle 5 on the folding wing 11 between a locked and an unlocked position can be actuated.

In a locked state in this case engage the locking elements 40 on the actuating linkage 42 of the folding wing 11 in the engaging elements 41 on the frame 10 one. The locking elements 40 For example, they may be designed in the manner of locking pins which engage or disengage from the engagement elements 41 in the form of suitable closing pieces can be brought. For adjusting the locking device 4 between their locked and their unlocked position, the actuating linkage 42 be adjusted along an actuating direction E, in order in this way the locking elements 40 in or out of engagement with the engagement elements 41 bring to.

For the purposes of the present invention acts, as in one embodiment in 6 is shown, at least one drive device 3 for pivoting the folding wing 11 relative to the frame 10 for opening or closing the flap device 1 is formed, even on the locking device 4 one and stands for this one in a slot 420 of the actuating linkage 42 engaging operating section 43 with the actuating linkage 42 in active connection. The drive device 3 This is about a on the push rod 31 arranged rod element 43 with the operating section 43 coupled, wherein the actuating portion 43 between the push rod 31 and a stop 317 of the rod element 315 comes to rest and over spring elements 37 ' . 38 ' between the push rod 31 on the one hand and the stop 317 on the other hand, on the rod element 315 is biased.

About the rod element 315 is the push rod 31 also with a holding section 114 to the folding wing 11 coupled by the rod element 315 the holding section 314 passes through, leaving the holding section 114 between a head 316 of the rod element 315 and a stop 318 to come to rest. For biasing the rod element 315 opposite the holding section 114 are spring elements 37 . 38 between the holding section 114 and the head 316 on the one hand and the holding section 114 and the stop 318 arranged on the other hand.

To unlock from a locked closed position, the push rod 31 analogously as described above, relative to the housing 30 adjusted. At first, this acts via the operating section 43 the push rod 31 on the actuating linkage 42 and adjusts this along the direction of actuation B, so that the locking device 4 is unlocked. Only after unlocking the locking device 4 is over the holding section 114 an adjusting force in the folding wing 11 initiated and above the folding wing 11 to open opposite the frame 10 pivoted.

To close this movement process is reversed, and after closing the folding wing 11 , so after approach of the folding wing 11 to the frame 10 , the operating section 43 in the slot 420 of the actuating linkage 42 is adjusted (or already before closing the folding wing 11 has been adjusted) and with further adjustment of the push rod 31 the actuating linkage 42 now in the reverse direction of actuation for a locking of the locking device 4 is pressed.

Due to the fact that the operating section 43 in the slot 420 of the actuating linkage 42 engages and over it at least to some extent relative to the actuating linkage 42 is adjustable, and in that the operating section 43 on the rod element 315 not fixed fixed, but elastic over the spring elements 37 ' . 38 ' is held, the locking device 4 basically also manually over the handle (see 5 ) are actuated, for example, in an emergency in case of power failure, a manual unlocking of the locking device 4 to enable. In addition, the operation section 43 when closing the folding wing 11 at least a certain way in the slot 420 Move to a change in position of the push rod 31 relative to the holding section 114 permit, without thereby the Betätigungsgestände 42 is pressed.

Another, compared to the embodiment according to 6 modified embodiment is in 7A to 7D shown. In this embodiment, the drive device 3 with her push rod 31 via an operating section 43 on a rod element 315 with the folding wing 11 coupled, wherein the actuating portion 43 in an opening 115 ' a holding portion performing a housing 114 ' of the folding wing 11 axially adjustable and articulated to some extent. About the case 114 ' and the engagement of the operating portion 43 in the opening 115 ' is the push rod 31 thus to the folding wing 11 hinged, wherein the actuating portion 43 in the case 114 ' also in a slot 420 an actuating linkage 42 a locking device 4 engages and thus, by adjusting the push rod 31 , also the locking device 4 can be operated.

In 7A is the drive device 3 in a position that the closed position of the flap device 1 equivalent. In this position, the locking device 4 locked. Accordingly, engage the actuating linkage 42 arranged locking elements 40 (please refer 5 ) in associated engagement elements 41 on the frame 10 one.

To open the flap device 1 becomes the push rod 31 extended in the adjustment V1, as shown in 7B is shown, and about the operating portion 43 in the opening 115 ' of the housing 114 ' emotional. This affects the actuating section 43 on the actuating linkage 42 and adjusts this along the direction of actuation B for unlocking the locking device 4 , wherein the actuating portion 43 on the actuating linkage 42 interacts with the edge of the opening 115 ' of the housing 114 ' gets into contact and thus before he has an adjusting force in the folding wing 11 initiates. After unlocking the operating section passes 43 with the border of the opening 115 ' in conditioning and thus takes the folding wing 11 with, so he through the drive device 3 initiated adjusting forces is opened.

When closing this runs the other way around. To close the push rod 31 in the opposite direction of adjustment V2 (see 7C ) retracted and about the operating section 43 moved over the one between the operating section 43 and the housing 114 ' acting spring element 44 on the case 114 ' and above it on the folding wing 11 acts and takes this. After reaching the closed position of the folding wing 11 becomes the push rod 31 further retracted, about the spring element 44 further tensioned (for example, driven to block) and the locking device 4 actuated by the additional adjustment of the operating section 43 on the actuating linkage 42 the locking device 4 acts and these in their locked position for locking the folding wing 11 with the frame 10 brings.

7D shows the flap device 1 in its locked closed position, in which the spring element 44 at least approximately drove to block.

The spring element 44 is dimensioned so that when closing the folding wing 11 not overly tensioned on pressure. Furthermore, the opening 115 ' of the housing 114 ' dimensioned so that after reaching the closed position of the folding wing 11 the operating section 43 in the opening 115 ' can still be moved sufficiently far to the locking device 4 to lock.

The idea underlying the invention is not limited to the above-described embodiments, but can also be realized in fundamentally different embodiments. In particular, other designs of spindle drives are possible in principle, as long as they allow a displacement of a push rod along a longitudinal axis.
