Description

The invention relates to a swivel drive for transferring a window sash that can be tilted and/or pivoted into a ventilation position.

In addition, the invention relates to a locking system that has a swivel drive according to the invention, and a ventilation system that has a swivel drive according to the invention.

Rooms, especially living rooms, in which people are present must be supplied with sufficient fresh air. For this purpose, it is common practice to exchange the used air for fresh air through a window. For this purpose, a window can be pivoted, for example, about a horizontal axis in the tilted position. However, it has been proven that this method of ventilation is not particularly efficient. It is cheaper to pivot a window sash for ventilation about a vertical axis into a ventilation position in which there is only a narrow opening gap of, for example, 12 mm. However, there is the problem of securely locking the window sash in this open position.

Out of DE 31 31 181 A1 a fitting for at least one rotatable and/or tiltable sash of a window, a door or the like is known. The fitting is used to enable energy-saving ventilation of a room over a longer period of time via a window or a door and is characterized by a latch to be attached to the sash, which is in working position with an attached to the fixed frame brought locking member acts together, wherein the wing is in a slightly open gap ventilation position when locking the catch.

Out of DE 84 27 019 U1 a stop for window sashes is known. The arrester has a holder to be fastened firmly to the window frame and at least one holder arm which is pivotably arranged on the holder and interacts with the window sash to be held and which has a receptacle for the window sash frame to secure the position of the window sash. The holder is designed as a U-shaped clamp holder that can be pushed onto the fixed window frame and removed again. At the end of the support arm, a second U-shaped clamp is provided for the releasable reception of the frame of the window sash, the second clamp being articulated on the support arm. This version of a locking device has the disadvantage of being very expensive to construct and cumbersome to operate.

Out of DE 1 764 109 U a locking device for tilt and turn casement windows is known. The locking device is used to lock a window when airing a room. Specifically, the locking device is designed to interact with a bascule lock. A cremone lock consists of a rotary handle arranged on the window frame with a locking lever and one or two locking rods moved by means of this rotary handle, which engage in the window frame at the top and bottom and thus cause the window to be locked. The locking device has an arm which is arranged in the path of movement of the locking rod perpendicularly on the window frame just above the window frame and has a plurality of detents in which the locking rod engages. Disadvantageously, this locking device is limited to windows that are provided with a bascule lock.

Out of DE 1 861 427 U a device for setting small ventilation positions on pivoting or turning windows is known. The device is designed to be used on a window whose sash has a crank handle provided with a cam to operate the central locking mechanism. It is characterized by a plate which is firmly connected to the window frame or is embedded in the latter and has at least two notches for the optional engagement of the hand lever cam, the notches lying one behind the other in the direction of movement of the sash.

It is the object of the present invention to specify a swivel drive which allows reliable and safe ventilation and which can also be designed in particular for automatic ventilation.

The object is achieved by a pivoting drive for transferring a tilting and/or pivoting window sash into a ventilation position, which is characterized in that the pivoting drive is designed and intended to be attached to a window sash and that the pivoting drive moves between a retracted position and a plunger that can be moved to an extended position, which is designed and intended to be supported with its free end on a window frame when the plunger is transferred from the retracted position to the extended position.

As far as components of a window are mentioned below, terms according to the following definition are used: Windows usually have a frame fixed to the building, in particular firmly connected to the outer wall of a building, and at least one window that can be moved, in particular pivoted, relative to the frame open wings The window sash in turn has a sash frame which carries at least one window pane. A locking fitting is used to fix a closed window sash to the frame. In most cases, the moving parts of a locking fitting are integrated into a sash frame and can be operated using a rotary handle. Here, a square pin with a square cross section often engages in a corresponding receptacle of the locking fitting and makes it possible for a torque to be transmitted from the rotary handle to the locking fitting.

It was recognized that a safe and reliable locking of a window sash in a ventilation position includes two very important detailed aspects. On the one hand, it should be ensured that the window sash locked in the ventilation position cannot be opened further beyond the ventilation position unintentionally, for example by wind or an unauthorized third party. On the other hand, it should be ensured that a window sash locked in the ventilation position does not slam unintentionally, for example due to drafts, which would be accompanied by annoying noises and permanent damage to the window sash and/or the frame.

According to a separate and independent idea of the invention, a holder for locking a tilting and/or pivoting window sash has at least one magnet in order to implement at least one of the two aspects mentioned with its magnetic force. The magnet can in particular consist of ferromagnetic material and be designed as a permanent magnet. However, it is also possible, particularly in the case of an electrically operated ventilation device which must be supplied with electricity anyway, for the magnet to be in the form of an electromagnet.

In particular, the retainer can have a counter-element designed to interact with the magnet. In a simple embodiment, the counter-element can consist of a paramagnetic material, for example a steel plate that can be simply screwed on. However, it is also possible for the counter-element to be designed as a permanent magnet, in particular made of a ferromagnetic material, or as an electromagnet.

In general, as will be explained in more detail below, the magnet can be attached directly or indirectly to a window sash, in particular to the sash of a window sash, while the counter-element with which it interacts in the ventilation position can be attached to the window frame.

In a particularly advantageous manner, the arrester according to the invention can be switched between a locking position, in which it holds a window sash in a ventilation position, and a release position, in which the window sash is released.

In a particularly advantageous manner, it can be provided that the arrester has a first arrester component that is designed and intended to be attached to or in a window sash, and that the arrester also has a second arrester component that is designed and intended for this purpose , to be attached to or in a window frame. It is possible here, for example, for the first locking component to have the magnet and the second locking component to have the counter-element. Conversely, however, it is also possible for the second locking component to have the magnet, while the counter-element is part of the first locking component.

As already mentioned, it can advantageously be provided that the first locking component and the second locking component interact in a locking position in which the locking device holds a window sash in its ventilation position. This can be realized in particular in that the first locking component and the second locking component are held together in the locked position by magnetic force. A particularly high holding force can be achieved in that the magnet and the counter-element are in direct contact with one another in the locking position.

In a particularly advantageous embodiment, the arrester has a bolt which is provided with a fastening element and is designed and intended to be fastened to a window frame by means of the fastening element. The bolt is preferably fastened to the window frame in such a way that its direction of longitudinal extension is aligned perpendicularly to the window surface of the closed window. The bolt is fastened with its fastening element to the window frame on the opening side of the window sash adjacent to the window frame of the window sash in such a way that the window sash can be opened and closed undisturbed; however, in such a way that a latch rotatably mounted on the bolt can be moved into the pivoting range of the window sash.

Advantageously, provision can be made in particular for the bolt to be mounted on the bolt so that it can move axially and by means of a spring is pressed against a limiting element at the free end of the bolt.

The length of the bolt can advantageously be selected in such a way that a window sash can only be pivoted out of its closed position until it hits the bolt pivoted into the pivoting range of the window sash, so that in this position there is a window opening gap of, for example, approx. 12 mm leaves. In this locking position, the bolt prevents the window sash from being opened further beyond the said ventilation position of 12 mm opening gap.

In a particularly advantageous embodiment, the width of the window opening gap of the ventilation position can be adjusted. It can be provided here, for example, that the part of the bolt that can be moved into the pivoting range of the window sash has a stop element whose position, in particular its distance from the window frame, can be adjusted, for example, with a screw drive. Such an embodiment also has the very special advantage that it can be adjusted more firmly to different configurations of the casement, in particular with regard to the extent by which the casement projects beyond the window frame in the closed state.

In particular, the bolt can have the magnet which, in the ventilation position, interacts with a counter-element fastened to the window sash, for example a plate made of a ferromagnetic material, and thus prevents the window sash from being accidentally moved from the ventilation position to the completely closed position (e.g. due to a draft). is pressed. The strength of the magnet is preferably dimensioned in such a way that the magnetic force can be overcome by such a draft or other events which should not lead to a complete closing of the window sash. In an embodiment with a stop element whose position can be adjusted, it can advantageously be provided that the stop element has the magnet.

In the event that the locking bolt described is to be used in combination with a locking mechanism according to the invention with a swivel drive, which is described further below, the bolt does not need to have a magnet. Rather, it is advantageous and sufficient here if the locking device, which has the swivel drive, also has the magnet. This is for the purpose of being able to pull the window sash back onto the window frame after a ventilation process, which is described in detail below.

In the event that a force is exerted on the window sash in the locked position, for example due to a draft, the arrester can absorb this by means of the spring, which presses the bolt against the end-side limiting element of the bolt. In this way it is effectively avoided that suddenly occurring forces acting on the window sash exceed the magnetic force and the window sash breaks away from the bolt.

Between the bolt and the limiting element there can advantageously be a buffer, for example a buffer made of an elastic material such as a rubber O-ring, which prevents the bolt, which has been moved axially against the force of the spring, from moving back hits hard and noisily on the end-side limiting element of the bolt.

In order to move the arrester described from the locking position to the release position, it simply has to be pivoted out of the pivoting range of the window sash. Since the user exerts a force perpendicular to the force which the magnet in turn exerts on the counter-element, the magnet can easily be detached from the counter-element by the user, in particular stripped off.

An embodiment in which two of the described arresters are attached to a window, namely in particular above and below the window handle on the opening side, is particularly advantageous and particularly safe, in particular particularly burglar-proof.

Another embodiment of a fastener according to the invention, which can be used alone or together with one or more of the bolt fasteners described above, has a rotary drive for transferring a tilting and/or pivoting window sash into a ventilation position. In particular, this arrester can have a motorized swivel drive for transferring a tilting and/or swiveling window sash into a ventilation position.

In particular, it can advantageously be provided that the pivoting drive is designed and intended to be attached to a window sash, the pivoting drive having a plunger that can be moved between a retracted position and an extended position. In its retracted position, the plunger does not prevent a window sash from closing completely. If the plunger is extended, its free end is supported on the window frame and thus presses the previously unlocked window sash into the ventilation position. Here the ram is in front preferably aligned with its direction of longitudinal extension perpendicular to the window surface and movably mounted perpendicular to the window surface.

The extended plunger prevents the window sash from being moved from the ventilation position back to the closed position.

In order to prevent the window sash from being opened further from the ventilation position and/or to be able to pull the window sash back towards the window frame after a ventilation phase, the plunger has the magnet at its free end, which is connected to a counter-element attached to the window frame interacting through magnetic force. Equivalently, it is of course also possible for the counter-element to have the magnet and for the plunger to be made of a material, in particular a paramagnetic material, which can interact with the magnet.

With this type of arrester, the magnetic force prevents the window sash from being opened further beyond the ventilation position, which could be a disadvantage in terms of burglary security. Particularly with regard to this, it can be advantageously provided that such a fastener is used together with one or more of the bolt fasteners described above. Such a combination has the particular advantage that the locking bolt(s) acts as a mechanical stop that effectively prevents a window sash from being opened further from the ventilation position. In addition, the arrester, which has the swivel drive, can transfer the window sash safely and reliably and in a very particularly advantageous manner by motor and/or automatically from the completely closed position to the ventilation position. In addition, the arrester having the plunger can move the window sash back into the fully closed position, in particular by motor, in that the plunger, which interacts by magnetic force with a counter-element arranged on the window frame, is retracted again until the window sash is completely closed. Even when the window sash is unlocked, such an arrangement is largely burglar-proof, regardless of whether the window sash is in the completely closed position or in the ventilation position.

It also plays a role here that it is usually not immediately apparent from the outside whether a window sash is completely closed or open by a few mm. As will be described in more detail below, with regard to this aspect it can advantageously be provided that the window sash can be transferred into an unlocked position without this being recognizable from the outside from the position of a rotary handle.

As already mentioned, with such a combination it is not necessary for the locking bolts to hold the window sash in the ventilation position by magnetic force, because this task has already been taken over by the locking device, which has the swivel drive. In this respect, it can be provided with such a combination that the locking bolts have no magnets and/or that no counter-element is mounted on the window sash with respect to the locking bolts, with which a magnet possibly present on the bolt could interact.

As already mentioned, the swivel drive can advantageously have an electric drive motor. This makes it possible, in particular, as also already mentioned, to move a window sash into a ventilation position and then to close it again remotely, in particular automatically at regular intervals and/or for predeterminable or predetermined ventilation periods.

In particular, the swivel drive can advantageously have a battery-powered drive motor. In addition, it can advantageously be provided that the swivel drive has an electric drive motor and a gear connected downstream of the drive motor, wherein the gear can advantageously be a self-locking gear. The transmission can in particular also be designed in such a way that it is self-locking only in the end positions of the ram, ie when the ram is fully retracted and when the ram is fully extended. For example, the transmission can have an eccentric and/or a crank mechanism. A self-locking gear has the advantage that the window sash is reliably held in the ventilation position or in the closed position without the drive motor having to be energized or short-circuited for this purpose.

In a particularly advantageous manner, the swivel drive can be designed to be remotely controlled by means of a remote control, in particular a wireless remote control.

A locking device with a swivel drive, in particular with a motor-driven swivel drive, already forms a very advantageous ventilation system that can also be operated completely automatically. However, the locking devices described above, regardless of whether they have a swivel drive or not, can only be used if the casement is unlocked. This can be done, for example, by manually moving a turning handle of a conventional locking fitting into an unlocking position.

However, in a ventilation system according to a special, advantageous, independent and independent inventive idea, there is an actuating device which has an electric actuating motor for transferring a locking fitting from a locking position into an unlocking position or from an unlocking position into a locking position. The actuating motor can in particular be battery-operated.

An actuating gear can advantageously be connected downstream of the actuating motor. The actuating gear can advantageously be a non-self-locking gear. Such a gear has the advantage that less energy is required to actuate it, and in this way any existing energy store, such as a rechargeable battery, is loaded less. For example, the actuating gear can be a crown gear.

Such a design has the very special advantage that not only the swivel drive can be controlled automatically in order to convert a window sash into a ventilation position. Rather, the locking fitting of the window can also be actuated accordingly beforehand, ie unlocked. After a ventilation phase, the window sash can be pivoted back into the closed position with the help of the rotary drive and then the locking fitting, in particular remotely controlled and/or automatically, can be transferred back into the locking position with the help of the actuating motor. Such a design is particularly burglar-proof because the window sash can also be locked in the phases in which it is not aired. In this respect, there is a double burglary protection in these phases, because a burglar would first have to lock the locking fitting and then overcome the or the arrester, which is an obstacle in particular if the arresters are designed like the bolt arresters described above.

As already mentioned above, it can advantageously be provided that the actuating device works in such a way that any rotary handle present on the window sash is not transferred into a rotary position when the window sash is unlocked, which position can be seen from the outside so that the window sash is unlocked. For this purpose, for example, there can be a freewheel that allows the actuating device to actuate the locking fitting without turning the rotary handle at the same time.

In particular, the actuating device can have a handle, in particular a rotary handle, for manual operation, which can be manually transferred to a first position, which is assigned to a locking position of the actuating device, or a second position, which is assigned to an unlocking position of the actuating device, wherein the Handle remains in its first position when the actuating device is switched from the locked position to the unlocked position by means of the actuating drive motor.

Alternatively, it can be provided that the actuating device for normal operation only allows motorized actuation and has no directly accessible handle. However, it is advantageous if such a performance provides an emergency actuation facility. This can be implemented, for example, in that there can be a coupling option for an emergency handle, for example a simple angle wrench. The possibility of coupling can be implemented, for example, by a receptacle into which an emergency handle can be inserted in a rotationally fixed manner. In particular, it can be provided that the coupling option is only accessible after a housing of the actuating device has been removed. The emergency handle can advantageously be detachably fastened on the inside of the housing, for example by means of a snap-in connection, so that it is immediately available to the user when required.

In an automatic system in particular, the actuating device can have an electronic sensor which monitors the position of the actuating device and/or determines the position of the actuating device and/or which is designed to detect vibrations and/or manipulations and, if necessary, to emit an alarm signal.

In this way, for example, it can be checked whether the actual position of the actuating device and/or the window sash corresponds to the position that should be present, in particular according to the last specification for ventilation or closing. If the actual position of the operating device and/or the window sash deviates from the position that should actually be present, a manipulation by a burglar may have occurred, so that an alarm signal can be issued. The alarm signal can be of an acoustic and/or optical nature. It is also possible for the alarm signal to be electrical or electromagnetic another location, for example to a receiver in another room or at a surveillance service or at the police station.

Also for burglary protection, it can advantageously be provided that the actuating device and/or the arrester are designed to detect vibrations and to emit a corresponding alarm signal if the detected vibrations exceed a predetermined or predeterminable level. In such a case, it can also be assumed that a burglary or an attempted burglary has occurred. Of particular advantage is a ventilation system that has a pivoting drive and, moreover, an actuating device, with the actuating device and the pivoting drive being arranged in a common housing and/or being operated with the same drive motor.

In particular, however, it is also possible for a common housing to be used with two separate drive motors. On the one hand, such an embodiment can be made particularly compact and, on the other hand, it is particularly flexible with regard to separate controllability of the actuating device and the swivel drive.

In a particularly advantageous manner, the arrester according to the invention and/or the ventilation system according to the invention can be designed as a retrofit kit for retrofitting existing windows. Alternatively or additionally, however, it is also possible for the arrester according to the invention and/or the ventilation system according to the invention to be designed to be installed during the manufacture of a window.

A control device can advantageously be present for controlling the actuating device and/or the swivel drive. In particular, the control device can be designed to control a number of locking devices and/or actuating devices, in particular in different rooms of a building. Here, as already mentioned, it can advantageously be provided that the control device transfers a window sash from a closed position to a ventilation position at predetermined or specifiable time intervals for a predetermined or specifiable ventilation period.

Alternatively, according to an independent idea of the invention, it can also advantageously be provided that the control device has a sensor for measuring a room air parameter, in particular the air humidity. The control device can move a window sash from a closed position to a ventilation position when a measured room air parameter exceeds a predefined or specifiable opening value, and/or move a window sash from a ventilation position to a closed position if a measured room air parameter falls below a predefined or specifiable opening value. The sensor can be designed and intended to be arranged alone or together with the control device, spatially separated from the swivel drive and/or the actuating device in a room, in particular a room that has windows provided for ventilation. In an advantageous embodiment, the sensor can transmit its measured values wirelessly. This aspect of the invention can be implemented particularly advantageously with the swivel drive described above, but this aspect of the invention is independent of a special design of a swivel drive.

Of particular advantage is a smart home system that includes a locking device according to the invention and/or a ventilation system according to the invention and/or a control device according to the invention.

According to an independent inventive concept, the swivel drive of the above-described arrester can also be used without a magnet to move a window sash from a closed position to a ventilation position, with locking in the ventilation position, in particular locking against opening beyond the ventilation position, by means of a arrester according to the invention, in particular a bolt arrester, as described above, can be done. Such a swivel drive can also be used in combination with other locking devices that are not according to the invention. In particular, such a swivel drive can also be designed without magnets and still have the additional features described above in relation to a locking device with a swivel drive.

If the arrester, which has a swivel drive, does not have a magnet, it would be advantageous if the plunger could be temporarily fixed to the window frame in another way, so that the swivel drive can pull the window sash back onto the window frame after a ventilation phase.

Alternatively, it is also possible to design the locking bolt in such a way that it moves the window sash back from the ventilation position to the closed position as soon as the plunger of the swivel drive is retracted. In such a design, neither the swivel drive nor the locking bolt need to have a magnet. For example, the bolt-lock ler have a bolt provided with a fastening element, which is designed and intended to be fastened to a window frame by means of the fastening element, the bolt carrying a movably mounted bolt. In particular, the bolt can be mounted on the bolt so that it can move axially and can be pressed in the direction of the fastening element by means of a spring. If the bolt is rotated into the pivoting range of a closed window sash, the window sash can be opened with the help of the pivoting drive against the force of the spring up to the ventilation position in which the bolt strikes a limiting element and prevents further opening. In this case, it can advantageously be provided that the plunger of the swivel drive presses against the window frame. If the plunger of the swivel drive is retracted again, the spring-loaded latch pushes the window sash back into the closed position. In this respect, a combination of a swivel drive and such a bolt-locking device forms an advantageous locking system that does not require a magnet.

1 shows in various detailed representations a locking device 1 for locking a tilting and/or pivoting window sash with double glazing 18 in a ventilation position. The lock has a magnet 2 which is arranged on a bolt 3 .

The arrester 1 has a bolt 5 connected to a fastening element 4, at the free end of which a limiting element 6, namely a collar, is arranged. The bolt 3 has a bore through which the bolt 5 runs. The bolt 3 can be rotated about the axis of longitudinal extension of the bolt 5 and thus transferred to different positions, which in 1a is shown. 1b shows the locking device in a top view. In this view it can be seen that the fastening element 4 is designed as a plate with a plurality of fastening bores 7 which can be screwed onto the frame; in such a way that the bolt protrudes perpendicularly from the frame. the 1c and 1d show the lock in different side views while 1e shows the arrester in cross section.

The locking device 1 has a helical spring 8 which is arranged concentrically to the bolt 5 and which is supported on the one hand on the fastening element 4 and on the other hand on the bolt 3, as a result of which the bolt 3 is pressed against the limiting element 6, namely the end collar of the bolt 5 becomes.

2 illustrates the functionality of the in 1 shown arrester. 2a shows the arrester 1 in a release position, in which the bolt 3 is pivoted out of the pivoting range of a window sash 9, so that the bolt 3 is inoperative when the window sash 9 is opened and closed. However, if the bolt 3 is rotated into the pivoting range of the window sash 9, the window sash 9 cannot go further than the ventilation position, which is in 2 B is shown to be opened. A counter-element 10 is attached to the window sash 9 and interacts with the magnet 2 in the locked position. This prevents the window sash from moving from the ventilation position to the closed position unintentionally, for example due to a draft. Rather, the window sash 9 is held in the locked position by the magnetic force of the magnet 2 . When a draft occurs, for example, which tends to push the window sash 9 into the closed position, the spring 8 cushions a movement of the bolt 3 .

The magnetic force can be designed so large that the connection of the magnet 2 to the counter-element 10 also remains when the window sash is moved to the closed position, for example manually. The magnet 2 and the counter-element 10 then remain in contact until the bolt 3 is in the release position ( 2a) is pivoted. The closed position, in which the magnet 2 is still in contact with the counter-element 10, is in 2c shown. However, it is also possible to design the spring force to be somewhat higher than the magnetic force. In this case, the bolt 3 is automatically separated from the counter-element 10 when the window sash 9 is closed manually.

3 shows a detail of a window with a sash 9, which by means of two arresters 1, as shown in the 1 and 2 are described, is held in the ventilation position.

The window also has a rotary handle 11 for transferring a locking fitting of the window from a locked position to an unlocked position or from an unlocked position to a locked position.

4 shows another fastener 12 having a first fastener component 13 and a second fastener component 14 . The second locking component 14 is designed as a counter-element 10 in order to interact with a magnet 2 of the first locking component. The first locking component is attached to a window sash 9, while the counter-element 10 is attached to a window frame 15.

The first locking component has a swivel drive with a movable plunger 16 . Triggered by a rotation of an operating lever 21, the plunger 16 can be moved between a retracted position and an extended position, in particular by a motor. In the closed window position, the in 4a is shown, the plunger 16 is in the retracted position. If the plunger 16 is extended, it pushes itself against the window frame 15 and thus presses the window sash 9 into the ventilation position, which in 4b is shown. The window sash 9 is secured against further opening and held in the ventilation position by the magnetic force between the magnet 2 and the counter-element 10 . By overcoming the magnetic force of the magnet 2, the window sash 9 can be opened further, manually or by motor, which in 4c is shown.

It is also possible, after a ventilation phase, to place the window sash 9 back on the window frame 9 by means of the rotary drive and thus to close the window. Here, the plunger 16, which holds onto the counter-element 10 with its magnet 2, is retracted again, as a result of which the window sash 9 is pulled against the window frame 9.

the 5a and 5b show the other arrester 12 in different side views, while 5c shows the other lock in the top view.

6 shows a detail of a window with a window sash 9, which is connected to two of the 1 shown arrester 1 and additionally with one of the in 4 shown arrester 12 is equipped in the ventilation position. In such an embodiment, the locking bar 1 does not need to have a magnet.

Transferring a window sash 9 from a closed position to a ventilation position presupposes that an existing locking fitting has been transferred from its locking position to an unlocking position. This can be done manually, for example by operating a rotary handle 11 .

However, an actuating device 17, such as that shown in 7 shown in different views, which one (in 7 drive motor, not shown) and additionally (for manual operation and/or emergency operation) has a turning handle 11 . The actuating drive motor can advantageously be arranged in a housing 19 of the actuating device 17 . With the help of the actuating drive motor, the locking fitting of a window can be operated via a square pin 20 in order to convert the locking fitting from a locking position into an unlocking position or from an unlocking position into a locking position.

In particular, this can be done in such a way that when the locking fitting is transferred from a locking position to an unlocking position, the rotary handle 11 is not moved, so that the position of the rotary handle does not indicate from the outside that the window is unlocked.

8th shows in different views a combination of the in 7 described actuating device 17 with the in 4 described arrester 12, which includes a pivot drive with a plunger 16.

9 shows a detail of a window with a window sash 9, which is connected to two of the 1 illustrated brakes and with the in 4 represent provided other locks 12 and with the in 7 illustrated actuating device 17 is equipped.

In this respect, the window has a special ventilation system in which all processes that are required for ventilation, in particular for regular ventilation, can take place automatically. In particular, provision can advantageously be made for this window to be unlocked at regular time intervals for predetermined and/or specifiable ventilation intervals and transferred to a ventilation position, with the window being automatically closed and locked again after each ventilation.

For this purpose, the locking fitting of the window is first switched into an unlocking position by means of an actuating device 17, in particular prompted by a control device. The window is then moved into the ventilation position with the help of the pivoting drive of the other arrester 12, where the window sash 9 strikes the bolt 3 of the arrester 1. After the ventilation interval, the window sash 9 is transferred back to the closed position with the other arrester 12, namely by retracting the plunger 16, and is locked there by means of the actuating device 17.

10 shows another embodiment of a locking device according to the invention, which essentially corresponds to the locking device 1, which is shown in FIGS 1 and 2 is shown. However, the part of the bolt 3 that can be moved into the pivoting range of a window sash has a stop element 22 whose axial position, namely its distance from a window frame, is adjustable. For this purpose, there is an adjusting screw 23 with which a corresponding relative movement of the stop element 22 relative to the remaining part of the bolt 3 can be effected. In this embodiment, the stop element 22 carries the magnet 2.

the 11a until 11c show different views of a ventilation system 24 which, in a common housing 25, has both an actuating device 17 for locking and unlocking a locking fitting and a locking device 12 with a swivel drive 35 which has a plunger 16. The actuating device 17 makes it possible to turn a square pin 20 either by motor or with the aid of a rotary handle 11 and thus to operate a locking fitting.

With the help of the swivel drive 35, a window sash, to which the ventilation system 24 is attached, can be moved into a ventilation position. Here, the plunger 16, at the free end of which a magnet 2 is arranged, is supported on a window frame. The ventilation system is attached to the casement frame of a window casement. A counter-element 10 (not shown in this figure) for the magnet 2 is fastened to the frame of the window.

the 12a until 12d show the ventilation system 24 in different representations. 12a shows the ventilation system 24 in a sectional view.

The ventilation system 24 has an electric actuating drive motor 26, at the output of which a pinion 27 is arranged. The pinion 27 meshes with a ring gear 28 which is connected to the square pin 20 in a torque-proof manner. By turning the square pin 20 it is possible to operate the locking fitting of a window. The ventilation system 24 is screwed onto the casement frame of a window casement in such a way that the square pin 20 engages in the corresponding receptacle of the locking fitting.

The square pin 20 can also be operated manually, namely with the aid of a turning handle 11 . This is the case, for example, in an emergency and/or when the power supply to the actuating drive motor 26 has failed (for example when the batteries are empty).

As already mentioned, the ventilation system 24 has a plunger 16, at the free end of which a stop element 22 with a magnet 2 is arranged. According to the same principle as in the in 10 described embodiment of a lock, the position of the stop element 22 can be adjusted relative to the remaining components of the plunger 16 with the help of an adjusting screw 23 here. This in particular in order to be able to adjust the width of the opening gap in the ventilation position.

The ram 16 can be moved, driven by a motor, between a retracted position and an extended position. The ram 16 is arranged laterally on a holding bridge 30 which is fastened to two guide rockers 31 . The guide rockers 31 are each rotatably mounted with pivot bearings 32 . Due to the great length of the guide rockers 31 compared to the adjustment path of the ram 16, the movement of the ram 16 together with its holding bridge 30 is almost linear. The plunger 16 can also be attached to the retaining bridge 30 in an alternative position 33, depending on whether the ventilation system 24 is to be used on a window sash 9 hinged on the left or on a window sash 9 hinged on the right.

In order to prevent the holding bridge 30 from tilting when the ram 16 moves, there are also stabilizer links 34 which are also pivotably mounted.

The swivel drive has a swivel drive 35 with which the plunger 16 can be moved. At the output of the swivel drive 35 there is an eccentric 36 which engages with a bolt 38 in a slot guide 37 connected to the holding bridge 30 .

The principle of the adjustment of the plunger 16 is clearly in the 13a and 13b shown in perspective. 13a shows the two guide rockers 31, which are pivotally mounted with the aid of pivot bearings 32. Arranged at the end of the guide rocker 31 is the retaining bridge 30 into which a retaining pin 29 of the plunger 16 can be inserted on both sides, depending on whether the ventilation system 24 is to be used on a window hinged on the right or on a window hinged on the left. The longitudinal guide 37 is located on the holding bridge 30, in which the bolt 38 of the eccentric 36 engages, which is coupled to the output of the swivel drive 35.

13b shows in particular the stabilizer links 34, which are connected to one another in a rotationally fixed manner and engage in fork-shaped receptacles 39 on the retaining bridge 30. The stabilizer rockers 34 serve to prevent the holding bridge 30 from tilting.

14 shows a locking bar 1 for a locking system which, in addition to the locking bar 1, has a swivel drive. On the one hand, the locking bar 1 has the task of preventing the window sash 9 from being opened further beyond the ventilation position. In addition, this special locking bar 1 has the task of moving the window sash 9 from the ventilation position back to the closed position as soon as the plunger 16 of the rotary drive 35 is retracted. In such an embodiment, neither the swivel drive 35 nor the locking bar 1 needs to have a magnet.

For example, the Rigel arrester can have a bolt 5 provided with a fastening element 4 , which is designed and intended to be fastened to a window frame 15 by means of the fastening element 4 , the bolt 5 carrying a movably mounted bolt 3 . The bolt 3 is mounted on the bolt 5 so that it can move axially and is pressed in the direction of the fastening element 4 by means of a spring 8 . When the bolt 3 is turned into the pivoting range of a closed window sash 9, the window sash 9 can be opened with the help of the pivoting drive 35 (in 14 not shown) against the force of the spring 8 up to the ventilation position in which the latch strikes a limiting element 6 and prevents further opening. Here, the plunger 16 of the pivoting drive 35 is pressed against the window frame 15 . If the plunger 16 of the rotary drive 35 is retracted again, the spring-loaded bolt 3 pushes the window sash 9 back into the closed position.
