Description

Drive system for fan

Technical Field

The present invention relates to a drive system for a door or window leaf, in particular for a door or window leaf of a smoke and heat emitting apparatus.

Background

The door or window leaf, in particular of the smoke and heat discharging device, should preferably not only be able to be driven for the opening and closing movement but also be able to be locked in the closed position.

Disclosure of Invention

The object of the invention is to provide a drive system of the type mentioned at the outset, by means of which the fan can be driven not only in an opening and closing movement but also locked in the closed position, wherein the system is of simple construction and/or easy to install, with as high a safety as possible in operation.

According to a first aspect of the invention, this object is achieved by a drive system according to claim 1. The drive system includes: an operating element for a locking device for locking a leaf to a frame of a door or window, the locking device being integrated in the leaf or the frame; an actuator coupled to the leaf, the frame and the operating element such that the leaf is movable between an open position and a closed position by the actuator, and the locking device is adjustable between an unlocked position and a locked position by the operating element when the leaf is closed.

The drive thus ensures not only the opening and closing movement of the fan but also the adjustment of the locking device. Thus, only one driver is required for both functions. By the following means: the drive causes an adjustment of the locking device by means of the actuating element, and the drive system itself can be constructed and installed particularly easily. It has been recognized that the locking device integrated in the fan or frame can also be adjusted by means of this one drive, which also opens and closes the fan, in particular by means of the operating element.

A locking device integrated in the fan is particularly preferred. In this connection, only this variant is mentioned below, it being clear that at least one movable part of the locking device, for example a linkage, can also be integrated in the frame.

An integrated locking device is to be understood to mean, in particular, a locking device which is not arranged flat on the fan or the frame. In particular, an integrated locking device is arranged between the inner and outer shells of the fan or frame. The locking means are preferably arranged within the chamber between the fan and the frame in the closed position, facing and/or active within the chamber. Furthermore, a locking device is also to be understood as meaning in particular a movable device, for example a linkage. The locking device can, for example, interact with a stationary counter-element on the respective other element, i.e. with a counter-element on the frame in the case of a fan-side locking device and with a counter-element on the fan in the case of a frame-side locking device.

With the drive system according to the invention, a plurality of locking points distributed over the circumference of the fan, in particular on different sides of the fan, can be achieved, despite the particularly low installation outlay. It is therefore not necessary to mount a device connecting a plurality of locking points on the fan or frame at the point of use. If the locking points are to be arranged on different sides, the installation of such a device is particularly complicated and complicated, since then a reversing mechanism is also required between the sides. Instead, it is advantageously possible to easily provide locking means, such as linkage means, in the manufacture of the fan system. Such integrated locking means are readily available, in particular also with a large number of locking points and with locking points on multiple sides of the fan. Although this results in slightly greater effort in the production of the fan system, the installation of the fan system at the point of use is greatly facilitated. As a result, the security against theft is thus also increased by the invention, since in a particularly simple drive a plurality of locking points on different sides can be realized in a simple manner.

Furthermore, the omission of a flatly mounted locking device has a positive aesthetic effect. Although the fittings are provided on one side, particularly on the frame and/or fan, the remaining sides of the frame and/or fan may be free of fittings.

According to one embodiment, the actuating element is inserted through the gap between the fan and the frame and/or is designed for this purpose. Thereby, no additional intervention on the fan or frame is required, for example through openings in the inner or outer casing of the fan or frame. The mounting is thereby further simplified and the stability of the fan and the frame is not affected by such openings. The gap may be a sealing gap, for example. For example, sealing elements, such as sealing lips and/or rubber seals, can be arranged in the gap. The gap may in particular be formed in the flap (or tip,

) And between the frames. The actuating element can in particular deform the sealing element, in particular in the closed position of the fan. It is also possible to use a manipulatorThe range of motion of the member is either free of the sealing element or free of the range of motion. In general, the manoeuvring element can for example engage into a cavity between the fan and the frame in the closed position.

Alternatively, it is possible for the actuating element to pass through an opening in the fan or the frame. This may, for example, prove to be optically advantageous in the mounted state, since the actuating element passing through the opening can easily be covered by a fitting, for example a fitting for mounting the drive and/or the other functional elements described herein, in any case. In principle, it is also conceivable to provide a plurality of actuating elements, for example one actuating element passing through the gap between the fan and the frame and one actuating element passing through an opening in the frame.

The actuating element can be moved along the frame and/or the fan, in particular in the gap or the sealing gap, for example by means of a drive, for adjusting the locking device. In this way, the adjustment movement of the drive can be transmitted to the locking device in a particularly simple manner.

According to a further refinement, the actuating element can be designed as a bending element and/or a plate element. The actuating element is thus easy to manufacture and can be adapted in a simple manner to the frame and the fan, in particular to the gap between them.

In a further embodiment, the actuating element is fixedly connected to an end (in particular a frame-side or a fan-side) of the drive. This enables a particularly reliable transmission of the actuating movement of the drive to the locking device.

According to one refinement, it is provided that the drive system comprises a spring which preloads the actuating element into the unlocking position, in particular can be overcome by the drive, in order to adjust the locking device into the locking position, wherein one end (in particular the frame-side or the fan-side) of the actuating element and/or the drive is fixedly connected to a tensioning element for the spring. This thereby ensures good transfer security in relation to the preloading device.

For example, it can also be provided that the drive system comprises a securing device which is designed to hold the locking device in the unlocked position as long as the fan is not in the closed position. The fastening device may comprise a trigger by means of which the locking device can be released for adjustment into the locking position. The fastening device can have a holding element and a held element, which interacts with the holding element for fastening. An end of the actuating element and/or of the drive (in particular on the frame side or the fan side) can be fixedly connected to the held element. Thereby, a good transfer security in relation to the fixation device is achieved. A retaining element is to be understood to mean, in particular, a retaining element which is stationary relative to the actuating element and/or the adjusting movement of the locking device and thus acts as a retainer. However, the holding element itself can be movable, for example, about an axis perpendicular to the direction of the actuating movement of the actuating element and/or for the purpose of, for example, entering into and exiting from the fastening position. If the held element is not held in the fixed position by the holding element, the held element in particular follows the adjusting movement.

The drive system may typically comprise a flat fitting, in particular for lying on the frame and/or the fan. The fitting can, for example, have a housing which, for example, comprises different functional elements. The actuating element can be arranged, for example, outside the housing. This makes particularly simple installation possible. Alternatively and optically advantageously, the actuating element can be arranged in the housing, in particular completely covered by the housing.

In an advantageous embodiment, the actuating element has a recess for engaging a driver element of the locking device.

The actuating element can be arranged, for example, on the frame side and for engagement with a driver element of the fan-side locking device or on the fan side and for engagement with a driver element of the frame-side locking device, such that the driver element engages with the actuating element, in particular with a recess of the actuating element, when the fan is moved into its closed position.

According to a second aspect, the object of the invention is also achieved by a drive system for a door or window sash according to the second independent claim. The drive system includes: an operating element for a locking device for locking the leaf to the frame of the door or window, the locking device being integrated in the leaf or frame, or a locking device for locking the leaf to the frame of the door or window; a drive which is coupled to the leaf, the frame and the operating element or the locking device such that the leaf can be moved between an open position and a closed position by means of the drive and the locking device can be adjusted between an unlocked position and a locked position when the leaf is closed; a securing device configured to hold the locking device in the unlocked position as long as the fan is not in the closed position, wherein the securing device comprises a trigger by means of which the locking device can be released for adjustment into the locked position; wherein the trigger can be triggered by the fan or the frame itself when the fan is moved to the closed position of the fan.

Known drive systems for the sash of a smoke and heat exhausting apparatus include a spindle drive mounted on the secondary closing edge of the window. Here, the drive opens and closes the window and additionally also locks the window. The locking is supported by a spring which does not yield when opening and closing the window, because the spring is heavier than the fan. Only when the window is closed will the driver continue to operate and compress the spring, thereby moving the linkage. However, if the fan is too heavy or the window is pushed open by wind, as may happen, the spring may yield when the window is opened. This may lead to a false locking, i.e. the locking device is adjusted into the locking position despite the window not being closed. Thereby, the window may be prevented from being completely closed.

The fixing means of the drive system according to the invention prevent such false locking. According to the invention, the fixing device or its trigger is triggered by the fan or the frame itself, in particular not by a fitting mounted on the fan. This makes it possible to achieve a particularly simple installation, since no additional fittings for the triggering element have to be installed. Furthermore, it is not necessary to provide such fittings with fixing holes, so that the stability of the fan is not impaired. Finally, this also has a visually positive effect if no additional fittings for triggering are provided on the fan.

In the present application, an embodiment is concerned in which the locking device is part of the drive system, preferably mounted flat on the frame, and an embodiment in which the locking device is integrated in the fan or the frame. In particular in the latter case, the locking device is adjusted by means of an actuating element. Whether the locking device is part of the drive system or of the fan or frame, the drive adjusts the locking device in the installed state, if necessary by means of the actuating element. Whenever one talks about that, for example, any adjusting movement and/or securing action is transmitted to the locking means, it is understood that the adjusting movement or securing action can be transmitted to the locking means of the drive system or to the locking means of the fan or frame by means of the operating element.

The trigger may in particular be arranged such that the fan or the frame triggers the trigger when the fan reaches its closed position. It can thus be ensured in a simple manner that the locking device is locked only in the closed position.

According to a further embodiment with a particularly simple design, it is provided that the trigger, at least with its carrying section interacting with the leaf, is arranged between the leaf and the frame, in particular between the flap of the leaf and the frame, in the closed position of the leaf.

The trigger can be arranged, for example, in a gap, in particular a sealing gap, between the fan and the frame in the closed position of the fan, in particular if a sealing element, for example a sealing lip and/or a rubber seal, arranged in the gap is deformed. Hereby, the deformability of such a sealing element is advantageously exploited, so that the trigger does not restrict the movement of the fan but is still effectively triggered. Instead, this deformation occurs in the vicinity of and in the closed position of the fan, which deformation allows on the one hand the fan to reach its closed position and on the other hand a reliable sealing despite the trigger. In particular, the sealing element is only locally deformed in the region of the trigger and/or is molded on the trigger. Alternatively, the gap can also be free of a sealing element in the region of the trigger and/or a recess can be provided in the sealing element for the trigger.

The trigger can, for example, be arranged on the frame side and in a fixed position in the movement space of the fan, so that the fan entrains the trigger into the release position during movement into its closed position. Alternatively, the trigger may be arranged on the fan side, for example, in such a way that the frame operates the trigger during movement of the fan into its closed position.

The trigger may be triggered, for example, by a flap of the fan. This makes a particularly simple construction possible.

According to a further embodiment, the trigger can have an actuating section, in particular a driving section, for interacting with the fan or the frame, and a transmission section for transmitting the trigger to the fastening device. Thereby, an advantageous functional separation is achieved.

Preferably, the handling section may be arranged closer to the frame than the transfer section. This makes it possible in a simple manner to design the functional components of the fastening device as desired and to mount them flat on the fan or on the frame, in particular to allow the fan to be used for triggering even when it is lying substantially flat on the frame. In other words, the overall height of the fastening device, in particular of the fitting comprising the fastening device, is independent of the shape of the fan and the frame, and in particular of the height of the gap between the fan and the frame.

The actuating section can be arranged offset relative to the transfer section toward the frame, for example.

In general, the handling section and the transfer section may be configured as staggered cylinder sections. The trigger or the segments can, for example, be configured as a curved bar, for example a round bar. In particular, a step, which is introduced in particular by bending, can usually be provided between the actuating section and the transmission section.

The securing means may optionally secure or release the locking means, in particular, for example via a hook mechanism. The fixing device can generally have a holding element and a held element. In general, the fixing means may act, for example, by form-locking or friction-locking.

According to one example, which is particularly simple in construction and visually attractive, it can be provided that the trigger protrudes from the housing of the fitting lying flat (in particular on the frame or the fan). The fastening device can be arranged in the housing, for example.

According to a third aspect, the object is achieved by a drive system for a door or window sash according to the third independent claim. The drive system includes: an operating element for a locking device for locking a leaf to a frame of a door or window, the locking device being integrated in the frame or leaf; or locking means for locking the leaf to the frame of the door or window; a drive coupled with the fan, the frame and the operating element or locking device such that the fan is movable between an open position and a closed position by the drive, and the locking device is adjustable between an unlocked position and a locked position when the fan is closed; a first securing device which is designed to hold the locking device in the unlocked position as long as the fan is not in the closed position, wherein the first securing device comprises a first trigger by means of which the locking device can be released for adjustment into the locked position; and a second fastening device, which is designed to hold the first fastening device in a fastening position, in which the locking device is held in the unlocked position, wherein the second fastening device comprises a second trigger, by means of which the first fastening device can be released for adjustment into the release position.

This ensures a particularly secure fixing of the locking device in its unlocked position. Even if the first fastening means have ensured a relatively good fastening, it may happen that the first trigger is operated at the wrong point in time, for example by hand or by an object, for example a playing child. Thus, the second fixing means results in fixing the first fixing means against erroneous operation. The following fact is thereby advantageously utilized: at least as long as the fan system is not intentionally disturbed, both flip-flops cannot be erroneously operated at the same time.

In general, the second flip-flop can be configured, for example, according to one of the above-described embodiments of the first flip-flop. The triggers are preferably of identical design and are arranged in particular in parallel.

According to one embodiment, the first and second fastening means are designed such that the second fastening means release the first fastening means only when both triggers are actuated simultaneously and/or synchronously. The trigger can thus be controlled in a particularly simple manner depending on the position of the fan.

The first and/or second trigger can be actuated in particular by the fan or by the frame itself, i.e. preferably not by an accessory mounted on the fan or frame, but for example by a flap of the fan. In general, reference may be made to the above description regarding the first flip-flop. The second flip-flop may be configured accordingly.

In a particularly simple and operationally reliable development, it is provided that the first and second trigger each have an actuating section for interacting with the fan, wherein the actuating sections are at the same distance from the frame and/or the fan at least in the respective release position and/or in the respective fastening position.

According to a further advantageous embodiment, it is provided that the second fastening device has a projection, in particular, which is fixedly connected to the first trigger, and a contour (in particular on a lever of the second fastening device) corresponding thereto for engaging the projection, wherein the projection and the contour are shaped and arranged such that, when the two triggers are not actuated simultaneously and/or synchronously, the projection engages the contour such that the first fastening device is locked against adjustment into the release position and/or the projection passes the contour only when the two triggers are actuated simultaneously and/or synchronously such that the first fastening device can be adjusted into the release position. The contour corresponding to the projection can be configured, for example, as a tooth contour (in particular with a plurality of teeth) and/or as a tooth profile. In general, for example, two opposite profiles, for example a tooth profile or a tooth profile, can also be provided, for example one for engaging when the first trigger is actuated first and one for engaging when the second trigger is actuated first. Thus, different operating scenarios can be reliably covered. The projection may be configured, for example, as a peg or pin. In general, the projection can be fixedly connected to a component of the first fixing device, for example a lever. Alternatively, the projection can also be fixedly connected to a component of the second fastening device, for example a lever. The corresponding contour can be fixedly connected to the component of the first fastening device. In other words, the co-acting element projections and profiles may be arranged in different ways.

In principle, it can be provided that the locking device or actuating element, the movable guide for one end of the drive, the spring for preloading the locking device and/or the fixing device for the locking device are mounted on the frame side, in particular the other end of the drive, on the fan, or that the locking device or actuating element, the movable guide for one end of the drive, the spring for preloading the locking device and/or the fixing device for the locking device are mounted on the fan side, in particular the other end of the drive, on the frame. In general, the drive system according to the invention can be mounted on the fan system in different ways. In principle, the other immovable end of the drive can be rotatably mounted.

The drive system may generally comprise, for example, a spring which preloads the locking device or the actuating element into the unlocked position. In this case, the preload can be overcome by the drive for adjusting the locking device into the locked position. A spring is generally understood to be a return means. For example, a coil spring may be provided. However, for example, gas springs are also conceivable. The relaxed position of the spring may correspond to the unlocked position of the locking device. The spring does not have to be completely relaxed here, but is only slightly tensioned in the tensioning position, which corresponds in particular to the locking position of the locking device.

The first and/or second fixing means can be preloaded into the respective fixing position, for example, by means of a spring, in particular a torsion spring, a bending spring, a leaf spring and/or a helical spring. In particular, the retaining elements of the respective fixing device can be preloaded in this way.

Typically, the locking device may be held in the unlocked position when the first fixation device is in its fixation position. Typically, the first fixation device may be held in its fixed position when the second fixation device is in its fixed position.

The first and/or second fastening device can, for example, have a lever, wherein, in particular, the trigger is arranged on one end of the lever. The lever is preferably swingable between a fixing position and a releasing position. The lever can be, for example, a holding element of the fastening device.

In particular, it can be provided that the drive moves the fan and adjusts the locking device by adjusting, in particular linearly, the distance between the end of the drive on the fan side and the end of the drive on the frame side. In principle, the drive can be suspended in particular movably between the fan and the frame. The drive can thus in particular be fixed neither to the frame nor to the fan, but can move relative to the frame and the fan. The drive is preferably mounted rotatably relative to the two elements and movably relative to one, in particular relative to the frame. The drive can typically be, for example, a spindle drive and/or a linear drive.

In one refinement, the drive system has a transmission element which is guided movably on the frame or the fan and is coupled, in particular fixedly connected, to the drive, the locking device or the actuating element, the spring and/or the fixing device, so that an adjusting movement of the drive relative to the fan is supported on the frame and so that the adjusting movement can be transmitted to the locking device or the actuating element and/or the spring.

The drive system may, for example, comprise a (in particular flat-lying) fitting, in particular a frame fitting, which comprises a locking device, an actuating element, a spring, a first and/or a second fixing device and/or a transmission element for transmitting an adjusting movement of the drive to the locking device. It is generally preferred that the locking device, the actuating element, the spring, the first and/or second fixing device and/or the transmission element can be mounted flat on the frame or the fan. Preferably, the spring, the fixing means and/or the transmission element may be arranged in a common housing. In principle, the actuating element can also be arranged at least partially in the common housing and can extend, for example, through an opening in the housing to the locking device.

The object of the invention is also achieved by a fan system according to the claims directed thereto. The leaf system, in particular a door or window, in particular for a smoke and heat exhaust device, comprises a frame, a leaf and a drive system according to one of the embodiments described above. In this case, the locking device, in particular for the fan, can be arranged integrated in the frame or the fan, wherein the actuating element of the drive system is coupled to the locking device.

The fan may typically be a tilting fan (or a tilt-in fan, kippflu gel), for example. The fan is preferably secured by a hinge located below, in particular tiltably secured about the hinge. The drive can be fastened to the fan and/or the frame, for example, by means of corresponding fittings. The drive or corresponding fitting can be fixed to the fan and/or frame, preferably on the right or on the left, i.e. generally on the secondary closing edge. In particular, the upper and/or lower side of the fan and/or the frame is/are free of fittings, at least except for fittings which may be provided for the hinge mounting.

Basically, the locking device, whether mounted flat on the frame or the leaf or integrated in the leaf or the frame, can be configured, for example, as a linkage. By means of one or more connecting rods, for example, one or more locking projections can be moved relative to the respective locking grooves and engage into these for locking. Conversely, it is also conceivable for the locking groove to be movable and to be engageable with a locking projection which is stationary in the adjustment direction for locking. Basically, the movable element can be arranged on the frame and the immovable element on the fan, or vice versa. It is generally preferred that the locking means is effective in the cavity between the frame and the fan. In particular, the fan and/or the frame may not have a flat-lying locking fitting.

It goes without saying that the subject matter of the different aspects and of the independent claims can advantageously be combined with one another, with embodiments described for the respectively different subject matter, and also with individual features described for the other subject matter.

Detailed Description

Fig. 1 shows a fan system, which is designed as a window 12. The window 12 can be opened and closed by means of a drive system 14, for example, in order to be used in a smoke and heat discharging device. Instead of the window 12, the drive system 14 can also be arranged on a door, for example.

The window 12 includes a frame 16 and a sash 18. The fan 18 is configured as a tilting fan and is arranged tiltably on the frame 16 by means of a hinge 20 located below. In this embodiment, the drive system 14 is arranged on the secondary closing edge, here on the left closing edge. Drive system 14 is secured to frame 16 by a flat frame fitting 22 and to fan 18 by a flat fan fitting 24. In this embodiment, the fan fitting 24 forms only a fixed, movement-proof fastening of the drive 26 of the drive system 14 to the fan 18, while the frame fitting 22 forms a movable support for the respective drive end and comprises a housing 28 in which a plurality of functional elements are arranged, as will be described in more detail below.

The drive 26 can be driven by a motor to vary the length between the frame-side end and the fan-side end, by means of which the fan 18 can be driven into an opening movement or a closing movement. Here, the driver 26 is supported on the frame side. The fan 18 is shown in its closed position in fig. 1. From the closed position shown here, extension of driver 26 causes sash 18 to open; in the closed position of the fan 18 shown here, the change in length of the drive 26 also causes a locking device integrated in the fan 18 to be locked or unlocked, as will be described in more detail below. The drive system 14 thus causes, via the single drive 26, not only the opening and closing movement of the fan 18 but also the locking or unlocking of the locking device of the fan system. The drive 26 is configured, for example, as a spindle drive.

Fig. 2 shows the drive system 14 in a different perspective view, wherein the fan 18 visible in fig. 1 is hidden. Only the frame 16 of the window 12 is visible. The frame fitting 22 is fixed with its housing 28 to the frame 16. The frame-side end of the drive is mounted on the frame fitting 22 or on the frame 16 so as to be movable relative to the frame 16. For this purpose, the transmission element 30 is mounted on the frame fitting 22 so as to be movable in the longitudinal direction.

An actuating element 32 is visible, which is fixedly connected to the transmission element 30 and the respective drive end and is therefore mounted so as to be movable relative to the frame 16. The actuating element 32 passes through a gap, not shown here, between the fan 18 and the frame 16 in order to actuate a locking device integrated in the fan 18. The actuating element 32 is designed as a curved plate, so that the gap between the fan 18 and the frame 16 or the contour of the gap can advantageously be mapped in the region of the gap. At the same time, the actuating element 32 has a high rigidity in the longitudinal direction of the frame 16, so that the adjusting movement of the drive 26 can be reliably transmitted via the actuating element 32 to the integrated locking device.

In the present embodiment, the actuating element 32 is arranged completely outside the housing 28. However, the actuating element for the integrated locking device may also be arranged at least partially inside the housing 28, for example. Thus, the actuating element may, for example, extend through an opening of the housing 28. Alternatively or additionally, it is possible for the actuating element to be completely covered by the housing 28. Such an actuating element can extend, for example, from the transmission element 30 through an opening in the frame 16 to a locking device, for example, integrated in the frame 16.

The drive system 14 also includes two triggers of the respective fixtures, namely a first trigger 34 and a second trigger 36. Corresponding fixing means are arranged in the housing 28 and will be described in more detail below.

Some functional elements arranged in the housing 28 are shown in an omitted manner in fig. 3. Unlike fig. 2, a fan 18 is also shown. The fixing element 32 is visible here as it extends into the gap 38 between the fan 18 and the frame 16.

A sealing element 40 is arranged in the gap 38, which sealing element is locally deformed by the actuating element 32. The actuating element 32 can be moved together with the respective end of the drive 26 along the frame 16 in the gap 38, wherein the sealing element 40 is deformed, i.e. is displaced by the actuating element 32. However, the sealing element 40 is configured to be resettable, so that, where all actuating elements 32 are not present, the sealing element 40 bears in a sealing manner against the frame 16 and the fan 18 in the gap 38. Alternatively, for example, the region of the actuating element 32 in the gap 38 can also be left free by the sealing element 40.

The drive system 14 comprises a first securing means 42 by means of which the locking means is held in the unlocked position by the operating element 32 as long as the fan is not in the closed position. Because fig. 3 shows the fan 18 in the closed position, the first securing device 42 is shown in the released position. In this case, the first fastening device 42 is held in the release position by the fan 18 itself, or is moved into the release position, in particular by the first trigger 34.

The drive system 14 comprises a second securing device 44 configured to hold the securing device 42 in a secured position in which the locking device is held in the unlocked position. In the present case, however, both the first fixing means 42 and the second fixing means 44 are in the release position. The second fastening device 44 is held in the release position or moved into the release position by the fan 18 itself via the second trigger 36. In fig. 3, the fan 18 is off and holds the two

triggers

34 and 36 or the

fixtures

42 and 44 in their respective release positions.

The drive system 14 further comprises a spring 46 which preloads the locking device into the unlocked position by means of the actuating element 32. The preload can be overcome by the actuator 26 to adjust the locking means into the locked position.

In the present case, the spring 46 is configured as a helical compression spring and is supported on the abutment 48. At the end of the spring 46 opposite the abutment 48, the spring is coupled to the transmission element 30 and thus to the drive 26. The transmission element 30 here forms a tensioning element for the spring 46. However, for example, separate tensioning elements can also be provided.

The longitudinal movement of the transmission element 30 compressing the spring 46 corresponds to an adjustment movement of the locking device into the locking position. In fig. 3, the spring 46 is shown in a tensioned or compressed position and the locking device is in a locked position.

The spring-relaxing movement of the transmission element 30 or the tensioning element corresponds to a movement of the locking device into an unlocked position in which the first and

second securing devices

42, 44 are also in their securing position when the fan 18 is not in its closed position, when the

triggers

34 and 36 are therefore not depressed by the fan 18. It is ensured, however, that a complete movement of the locking device between its unlocked position and its locked position only takes place if the door leaf 18 is in the closed position.

Fig. 4 shows the window 12 of fig. 1 in a sectional view in the region of the drive system 14. The profile is located here in the region of the second trigger 36 of the second fastening device 44. The frame-side end of the driver 26, the housing 28 of the frame fitting 22, and the frame 16 and the fan 18 are also visible. In the background, the steering element 32 is visible as it extends through the gap 38 between the frame 16 and the fan 18.

An integrated locking device 50 is provided on the fan 18, which locking device is designed as a link fitting, wherein the adjusting movement between the locked position and the unlocked position extends perpendicular to the image plane of fig. 4. The locking device 50 is arranged between an inner housing 51 of the fan 18 and an outer housing, which is not visible here. The locking device 50 is also effective in the chamber 53 between the fan 18 and the frame 16 in the closed position.

The driver element 52 is connected to the locking device 50, which is engaged with the actuating element 32, so that a longitudinal movement of the actuating element 32, i.e. a movement perpendicular to the image plane of fig. 4, is converted into a corresponding adjusting movement of the locking device 50. This adjusting movement can be transmitted to the locking points and the other side of the sector 18 by means of a link and a deflection device in a manner known per se.

The driver element 52 engages in a corresponding recess 54 of the actuating element 32, which recess can be seen, for example, in fig. 2. The recess 54 is shaped such that, when the fan 18 is closed, the rear engagement section 56 engages behind the actuating element 32 from the angle of the locking device 50, wherein the driving section 58 engages through the actuating element 32. The actuating element 32 interacts in the longitudinal direction with the driver section 58 in order to transmit the adjusting movement. The rear engagement section 56 interacts with the actuating element 32 in order to precisely position the actuating element 32 relative to the driver element 52.

The second trigger 36 comprises a transmission section 60 for transmitting the trigger to the fastening device 44 and an actuating section 62 for co-acting with the fan 18, in particular for being carried along by the fan 18 when the fan is moved into its closed position. The

sections

60 and 62 are configured as staggered cylinder sections, wherein the handling section 62 is arranged closer to the frame 16 than the transfer section 60. As can be seen from fig. 4, the overall height of the fastening device 44 is essentially independent of the function of the trigger 36.

When the fan 18 is in the closed position as shown, the manipulation section 62 is disposed in the gap 38 between the fan 18 and the frame 16, specifically between the flap 64 of the fan 18 and the frame 16. Here, the sealing element 40 arranged in the gap 38 is locally deformed by the actuating section 62 of the trigger 36. The first trigger 34, which is hidden in fig. 4 but is visible in fig. 2, for example, is constructed and arranged in correspondence with the second trigger 36.

In fig. 5, the frame fitting 22 is shown in longitudinal section. Furthermore, the spring 46, the transmission element 30 and the first and second fixing means 42, 44 can be seen. The transmission element 30 is connected to the first fastening device 42 via a rod 66, which is arranged and guided movably in the longitudinal direction by a guide element 68.

The spring 46 is in particular dimensioned in such a way that it bears the weight of the fan 18 during normal operation, which weight is transmitted to the spring 46 via the drive 26. Thus, even without the securing

devices

42 and 44, it is ensured in principle that the locking device 50 is moved into its locking position when the fan 18 is closed. The

fixtures

42 and 44 are provided for the following cases: the fan 18 is subjected to particular, unpredictable loads, such as those experienced by storms or children playing with a ball.

In fig. 6, the frame fitting 22 is shown enlarged in the region of the

triggers

34 and 36. Here, the actuation section 62 arranged offset is not shown, but only the transfer section 60 is visible. The

triggers

34 and 36 extend from the

fastening devices

42 and 44, which are not visible here, arranged in the housing 28 through corresponding openings 70 of the housing 28. The

triggers

34 and 36 are shown in a fixed position, i.e., not depressed or held in a released position from the direction of the fan 18 toward the frame 16, as in fig. 3 and 4, respectively. Thus, the position shown in FIG. 6 of the

triggers

34 and 36 corresponds to a fan position other than the closed position of the fan.

The working principle of the first and second fixing means 42, 44 is explained in more detail below with reference to fig. 7 to 10, which in fig. 7 to 10 show the fixing means 42 and 44 in different positions in respective sectional views.

In fig. 7, the

fixtures

42 and 44 are in their respective fixed positions as in fig. 6. The first fixation device 42 includes a retaining element 72 and an element 74 held in a fixed position by the retaining element 72. The held element 74 is fixedly connected to the lever 66 and thus to the transmission element 30, the drive 26 and the actuating element 32. The holding element 72 is designed as a lever and is mounted rotatably on a lever shaft 76. The lever or holding element 72 is preloaded into the fixing position shown here by means of a spring 78 and can be brought from the fixing position into the release position against the spring 78 by means of the trigger 34, i.e. by pressing the trigger 34 downwards in the direction of the frame 16 (downwards in fig. 7).

The first fastening device 42 is designed here as a hook mechanism. The retained element 74 includes a hook section 80 that engages with a hook section 82 of the retaining element 72 and disengages when the retaining element 72 moves to the release position. Only in this way is the locking device 50 or the actuating element 32 released, so that the locking device 50 can be adjusted into the locked position.

The second fastening device 44 comprises a projection 84, here embodied as a pin, which is arranged fixedly on the held element 72 or on the lever of the first fastening device 42. The second fixing device 44 also comprises a lever 86 which is rotatably supported about a lever shaft 88. The lever 86 includes a profile corresponding to the projection 84 for securely engaging the projection 84. In particular, the lever 86 has two opposite tooth profiles 90, each having a plurality of teeth for engagement with the projection 84. In this case, a channel for the projection 84 is arranged between the teeth, which channel is shaped such that the projection 84 passes the projection 84 through the tooth profile 90 only when the

triggers

34 and 36 are actuated simultaneously and synchronously, and engages in a locking manner with one of the teeth of the tooth profile 90 in the event of an uneven actuation of the

triggers

34 and 36.

The lever 86 is preloaded into a fixed position by a spring 92 similar to the lever 72. But only when the first trigger 34 is operated simultaneously and synchronously with the second trigger 36, the lever 86 can be moved by means of the second trigger 36 against the spring 92 into the release position of the second fixing means 44. Otherwise, the projection 84 engages into one of the tooth profiles 90. In this state, an operating force applied to the second trigger 36 in a direction toward the frame 16 (downward in fig. 7) causes a force on the projection 84 through the lever 86, which is opposite to the operating direction of the first trigger 34. Thus, the first trigger 34 and the first securing device 42 are locked in a secured position. This is shown in fig. 8. Here, only the second trigger 36 is pressed slightly downwards towards the frame 16, whereas the projection 84 thereby engages with the teeth of the tooth profile 90 and the lever or holding element 72 of the first fixing means is locked in the fixing position.

If, instead, only the first trigger 34 is actuated, the projection 84 engages with the other, opposite tooth profile. Depending on whether the first trigger 34 or the second trigger 36 is pressed further down towards the frame 16, the projection 84 engages with one or the other of the tooth profiles 90, possibly not with the first tooth as shown in fig. 8, but with the downstream tooth as shown further down in fig. 8. In a simple manner, it is thereby ensured that the first fastening device 42 is adjusted into the release position only when the first and

second triggers

34, 36 are actuated simultaneously and synchronously over their entire path or pressed downward toward the frame 16. According to the invention, this simultaneous and synchronized manipulation is achieved by the fan 18 itself, which is close to its closed position.

In fig. 9, the first and

second securing devices

42, 44 are shown in respective release positions. During simultaneous and synchronized manipulation of the

triggers

34 and 36, the projection 84 has passed the tooth profile 90. The

hook segments

80 and 82 or the retaining element 72 and the retained element 74 are no longer engaged with each other. The locking device 50 can now be adjusted into its locking position by the actuating device 32. The held element 74 is moved to the right in relation to fig. 7 to 10. The position of the held element 74 corresponding to the locking position of the locking device 15 is shown in fig. 10. The

fixtures

42 and 44 or the

triggers

34 and 36 are in the release position because the

triggers

34 and 36 are pressed down against the

springs

78 and 92 by the fan 18, that is to say are held in the release position.

The

triggers

34 and 36 are released again by the fan 18 when the fan 18 leaves its closed position, i.e. because of the locking device 50, which releases the fan 18 only when the locking device has reached its unlocked position. At this point in time, the held element 74 is moved again so that the first fixing means 42 can be engaged.

The

levers

72 and 86 are then adjusted into the respective fixed positions again by the

springs

78 and 92. In this case, the projection 84 passes through the tooth profile 90. The teeth of the tooth profile 90 are designed in a direction-dependent manner in such a way that they do not lock the projection 84, but rather the projection can slide down on the teeth until the two

fastening devices

42 and 44 are again in the respective fastening position. Then, the projection 84 is stopped in the stop groove 94 provided therefor.

Thus, the first securing device 42 prevents the spring 46 from yielding when the window is open. To this end, the spring 46 is locked by opening the window 12 and the spring 46 is released again when the window 12 is closed. The fan 18 presses the lever-shaped trigger 34 downward and thus unlocks the first fastening device 42 when it is closed. Thereby, the spring 46 may be compressed again and the window 12 locked. Since the trigger 34 of the first fixing device 42 protrudes from the housing 28 and is therefore uncovered, an erroneous operation may occur when the window 12 is opened, for example when the trigger 34 is pressed down when the window 12 is opened. In order to prevent incorrect operation of the first fastening device 42, a second trigger 36 is provided, which actuates the second fastening device. The first securing device 42 can only be unlocked when the two

triggers

34 and 36 are pressed downwards in parallel. If only one of the two

triggers

34, 36 is pressed downward, a locking is brought about by the tooth profile 90 in the second fixing device. The lug 84, which is designed in the manner of a pin or a bolt, is thereby wedged into the toothed or toothed profile 90. If the two

triggers

34 and 36 are pressed downward in parallel, the projection 84 passes through the tooth profile 90 without contacting and tilting the tooth profile. If the lever 72 or the holding element of the first fixing means 42 is pressed downwards, the held element 74 can move freely with the hook section 80 and the spring 46 can be compressed by the driver 26. Thus, in the open state of the window 12, the described first fixing device 42 locks the spring 46, so that no false locking occurs. Furthermore, the second fixation device 44 prevents an undesired unlocking of the first fixation device. The second fastening device 44 thus forms a faulty operating lock and an additional fastening safeguard.

It can be seen that the embodiment described comprises a drive system 14 by means of which the fan 18 can be driven not only in an opening and closing movement but also in a closed position, wherein the system is simple in construction, easy to install and has a high degree of operational safety.

The described drive system 14 can also be installed in principle in the opposite way to that shown, with minor structural modifications, i.e. the fitting 22 can be arranged on the fan 18 and the fitting 24 on the frame 16. In this case, for example, the trigger of the fastening device can be guided around the fold 64 of the leaf 18. The operating element may be configured such that it passes through an opening in the fan 18. In principle, a variant is also conceivable in which the drive system 14 is arranged on the side facing away from the hinge.
