The invention relates to a window or door fitting with a hand lever which has a polygonal shaft mounted thereon in a rotationally fixed manner, said shaft passing through a bore in the leaf/sash and projecting into a drive device of an espagnolette fitting and being coupled to the latter. In order to achieve the fastening of the hand lever (6) with only minimal effort when processing the leaf/sash (1) and to avoid the transmission of operating forces or spring forces to the drive device and to be able to fasten the arrangement to the leaf/sash (1) as invisibly as possible, there is provision that the polygonal shaft engages at least in certain regions in a follower (12) situated coaxially to the polygonal shaft, said follower being mounted in a housing (15) in a rotatable, but axially non-displaceable manner, wherein the housing (15) is fastened so as to be offset parallel to the drive direction along the axis of rotation of the polygonal shaft (7), and the follower (12) has means which act in the axial direction for coupling to the polygonal shaft (7) in a positively or frictionally locking manner.

Description

Fenster oder Türbeschlag Window or door fittings
Üblicherweise finden bei Fenstern und Türen Handhebel mit einer Mehrkantwelle Verwendung, welche auf einer Sichtfläche des Flügels montiert werden und die mit einer Rosette versehen sind. Die Rosette lagert Befestigungsschrauben, welche bis zu dem Treibstangenantrieb reichen und dort ein Widerlager finden. Die Rosette beinhaltet zudem eine Rastung zur bedarfsgerechten Kenntlichmachung der Schaltstellungen des Treibstangenantriebs, welche mit der Mehrkantwelle antriebsverbunden ist. Es werden üblicherweise drei Bohrungen in die Flügelrahmensichtfläche eingebracht, welche die Mehrkantwelle und die Usually hand levers with a polygonal shaft are used in windows and doors, which are mounted on a visible surface of the sash and which are provided with a rosette. The rosette stores fastening screws that extend to the drive rod drive and find an abutment there. The rosette also contains a detent for the needs-based identification of the switching positions of the drive rod drive, which is drive-connected to the polygonal shaft. There are usually three holes drilled into the sash visible surface, which is the polygonal shaft and the

Aus der DE 4230476 B4 und DE 4238459 A1 ist ein Fenster- und Türbeschlag bekannt geworden, bei dem ein Handhebel mit einer drehfesten, daran angebrachten Mehrkantwelle versehen ist. Die Mehrkantwelle durchdringt eine Bohrung im Flügel und reicht bis in eine Mehrkantwellenaufnahme einer Antriebsvorrichtung eines Treibstangenbeschlages. Die Antriebsvorrichtung weist ein Zahnrad auf, in welche die Mehrkantwelle eingreift. Das Zahnrad ist in einem Gehäuse gelagert, das in einer Ausnehmung des Flügels untergebracht ist. Die Mehrkantwelle besitzt an ihrem, dem Zahnrad zugewandten Ende ein Rastmittel, welches einer Radialbohrung in dem Zahnrad zuordenbar ist und eine in axialer Richtung wirksame Fixierung der Mehrkantwelle an der Antriebsvorrichtung ermöglicht. Die Vorrichtung erlaubt damit eine Befestigung des Handhebels ohne Schrauben. From DE 4230476 B4 and DE 4238459 A1 a window and door fitting is known in which a hand lever is provided with a non-rotatable, polygonal shaft attached to it. The polygonal shaft penetrates a hole in the sash and extends into a polygonal shaft receptacle of a drive device of a drive rod fitting. The drive device has a gear in which the polygonal shaft engages. The gear wheel is mounted in a housing which is accommodated in a recess in the wing. At its end facing the gear, the polygonal shaft has a latching means which can be assigned to a radial bore in the gear and enables the polygonal shaft to be fixed to the drive device in an axial direction. The device thus allows the hand lever to be attached without screws.
Aus der DE 9418857 U1 ist es in Ergänzung dazu bekannt, den Handhebel in axialer Richtung durch ein Federelement gegen den Flügel abzustützen, so dass die fest im Handhebel befestigte Mehrkantwelle mit ihrem Rastelement das Zahnrad hintergreift und hinter diesem radial verrastet. Die Rastverbindung bleibt durch die Abstützung des Handhebels stets kraftbeaufschlagt. Eine zweite Feder beaufschlagt zudem eine drehfest auf der Mehrkantwelle gelagerte Rasthülse, die sich auf dem Gehäuse der Antriebsvorrichtung abstützt. Das Gehäuse soll eine dazu komplementär ausgebildete Rastplatte bilden, welche zusammen mit der Rasthülse eine die Schaltstellungen des Treibstangenbeschlags kennzeichnende From DE 9418857 U1 it is also known to support the hand lever in the axial direction by a spring element against the wing, so that the polygonal shaft fixed in the hand lever engages behind the gear with its locking element and latches behind it radially. The locking connection always remains subject to force due to the support of the hand lever. A second spring also acts on a locking sleeve which is rotatably mounted on the polygonal shaft and which is supported on the housing of the drive device. The housing is intended to form a locking plate which is designed to be complementary to this and which, together with the locking sleeve, characterizes the switching positions of the drive rod fitting

Entkopplungseinrichtung. Die DE 1193829 A offenbart ebenfalls eine schraubenlose Befestigung des Handhebels, bei dem die Mehrkantwelle das Rastelement selbst bildet. Eine Feder bewirkt auch hier eine sichere Verrastung hinter der Nuss eines Schlosses. Decoupling device. DE 1193829 A also discloses screwless fastening of the hand lever, in which the polygonal shaft forms the locking element itself. Here, too, a spring ensures a secure latching behind the nut of a lock.
Die schraublose Befestigung des Handhebels ist ein grundlegendes Bedürfnis bei der Fenstermontage, da die Fenster ohne montierten Hebeln enger transportiert werden können und die Gefahr einer Beschädigung der Fenster durch die Hebel reduziert wird. Die Handhebel werden bei den zuvor genannten Bauelementen daher nach Montage des Rahmens in der Gebäudeöffnung montiert. Die dadurch erreichten Vorteile bringen aber entscheidende Nachteile mit sich. Die zuerst genannten Ausgestaltungen erlauben keine Rastung zur Kennzeichnung der Schaltstellungen und benötigen einen Freiraum für die das Zahnrad durchdringenden Mehrkantwelle. Die weiter genannten Ausführungen mit Rastungen benötigen neben dem Freiraum besonderer Wartung. Durch die axial wirkenden Federn werden die Zahnräder in den Antriebsvorrichtungen stets in Richtung der rauminnenseitigen Gehäusewand kraftbeaufschlagt und die auf den Handgriff wirkenden axialen Kräfte wirken in gleicher Richtung. Nach einem gewissen Zeitablauf kommt es daher zu Verschleißerscheinungen an den Antriebsvorrichtungen und die Handhebel lockern sich nach Ermüdung der Federn. Der Verschleiß sorgt auch für eine unzureichende radiale Lagerung der Mehrkantwelle, was zu weiterem Verschleiß führt. The screwless fastening of the hand lever is a fundamental requirement when installing windows, since the windows can be transported closer together without the levers installed and the risk of damage to the window by the levers is reduced. In the case of the aforementioned components, the hand levers are therefore installed in the building opening after the frame has been installed. The advantages achieved in this way, however, have decisive disadvantages. The first-mentioned configurations do not allow latching to identify the switching positions and require a free space for the polygonal shaft penetrating the gearwheel. The designs with detents mentioned above require special maintenance in addition to the clearance. Due to the axially acting springs, the gears in the drive devices are always acted upon by force in the direction of the housing wall on the inside of the room and the axial forces acting on the handle act in the same direction. After a certain period of time, there is therefore signs of wear on the drive devices and the hand levers loosen after the springs are tired. The wear also ensures insufficient radial support of the polygonal shaft, which leads to further wear.
Um die Befestigung des Handhebels rosettenlos erscheinen zu lassen, wurde in der In order to make the fastening of the hand lever appear rosette-free, the
WO 002008068304 A2 bereits ein Adapter vorgeschlagen, der unmittelbar hinter einem Steg des Flügelprofils als Widerlager für Befestigungsschrauben einer Rosette dient. Die WO 002008068304 A2 has already proposed an adapter which serves as an abutment for fastening screws of a rosette immediately behind a web of the wing profile. The
Betätigungs- und Bewegungskräfte werden auf den Adapter übertragen, welcher sich gegen die Antriebsvorrichtung abstützt. Diese Ausgestaltung setzt eine besondere Rosette und einen dazu passenden Hebel voraus. Actuation and movement forces are transmitted to the adapter, which is supported against the drive device. This configuration requires a special rosette and a matching lever.
Aufgabe der Erfindung ist es, eine Ausgestaltung zu treffen, bei der die Befestigung des Handhebels nur minimalen Aufwand bei der Bearbeitung des Flügels verursacht und es zu keiner Übertragung von Bedienungs- oder Federkräften auf die Antriebsvorrichtung kommt. Die Anordnung soll möglichst unsichtbar an dem Flügel angebracht sein und auch bei engen Platzverhältnissen nutzbar sein. Zur Lösung sieht die Erfindung bei einem Gegenstand nach dem Oberbegriff des Anspruchs 1 vor, dass die Mehrkantwelle zumindest bereichsweise in eine koaxial zur Mehrkantwelle liegende Nuss eingreift, die drehbar, aber axial unverschiebbar in einem Gehäuse gelagert ist, wobei das Gehäuse entlang der Drehachse der Mehrkantwelle parallel zur Antriebsrichtung versetzt befestigt ist und die Nuss in radialer Richtung wirksame Mittel zum form- oder reibschlüssigen Koppeln mit der Mehrkantwelle aufweist. The object of the invention is to achieve an embodiment in which the attachment of the hand lever causes only minimal effort when machining the wing and there is no transmission of operating or spring forces to the drive device. The arrangement should be attached to the wing as invisibly as possible and should also be usable in confined spaces. To solve this, the invention provides for an object according to the preamble of claim 1 that the polygonal shaft engages at least partially in a nut lying coaxially to the polygonal shaft, which is rotatably but axially immovable in a housing, the housing along the axis of rotation of the polygonal shaft parallel to the drive direction is attached offset and the nut has effective means in the radial direction for positive or frictional coupling with the polygonal shaft.
Diese Ausgestaltung erlaubt die Einleitung der Bedienkräfte in die Nuss, welche unabhängig von der Antriebsvorrichtung in einem zweiten Gehäuse koaxial zum Gehäuse der This configuration allows the introduction of the operating forces into the nut, which are independent of the drive device in a second housing coaxially to the housing
Antriebsvorrichtung gelagert ist. Die Nuss nimmt alle axialen und radialen Kräfte auf und beansprucht keinen sichtbaren Bauraum. Da nur axiale und radiale Kräfte aufgenommen werden müssen kann die Nuss und ihre Lagerung sehr vereinfacht ausgeführt werden. Die Mehrkantwelle erhält zudem eine zweite axial versetzt liegende Lagerung, was die Drive device is mounted. The nut absorbs all axial and radial forces and does not take up any visible installation space. Since only axial and radial forces have to be absorbed, the nut and its mounting can be made very simplified. The polygonal shaft also receives a second axially offset bearing, which
Anforderungen an die Bauteile weiter reduziert und das Zahnrad der Antriebsvorrichtung wirkungsvoll entlastet. Die Befestigung ist dadurch auch an Ganzglasflügeln möglich, welche einen schmalen Isoliersteg hinter einer der Scheiben aufweisen. The requirements on the components are further reduced and the gear wheel of the drive device is effectively relieved. It can also be attached to all-glass sashes that have a narrow insulating web behind one of the panes.
Um die Rastung zur Kennzeichnung der Funktionsstellungen zu realisieren ist vorgesehen, dass die Nuss eine Rastung aufweist, welche die Nuss in vier gleichmäßig verteilten In order to realize the latching for identifying the functional positions, it is provided that the follower has a catch that evenly divides the follower into four

Vereinfacht wird die zuletzt genannte Ausgestaltung dadurch, dass die Rastung durch zumindest eine Rastfeder bewirkt wird, die mit einem Rastvorsprung in eine Rastausnehmung der Nuss eingreift. The last-mentioned embodiment is simplified in that the latching is brought about by at least one latching spring which engages with a latching projection in a latching recess in the nut.
Um die funktionelle Verbindung mit dem Antrieb sicherzustellen ist vorgesehen, dass das Gehäuse zur Aufnahme von Befestigungsmitteln mit dem Treibstangenantrieb geeignete Bohrungen aufweist. In order to ensure the functional connection with the drive, provision is made for the housing to have suitable bores for receiving fastening means with the drive rod drive.
Eine einfache und wirkungsvolle Verbindung der Nuss mit der Mehrkantwelle wird erreicht, wenn die Mittel zur Kopplung mit der Mehrkantwelle aus einer Madenschraube bestehen. A simple and effective connection of the nut with the polygonal shaft is achieved if the means for coupling with the polygonal shaft consist of a grub screw.

The polygonal shaft 7 penetrates the hole 11, the sleeve 9 and the nut 12 of the adapter 13 and extends to the drive device 14. The The adapter 13 and the drive device 14 are assigned to an extension of the fitting groove 4 in the assembled state.

Zudem weist das Gehäuse 15 zwei Befestigungslappen 18 auf, die mit Bohrungen 19 das Anbringen von Befestigungsschrauben 20 ermöglichen. Dadurch ist der Adapter 13 sicher festgelegt. The drive device 14 are coaxially aligned with respect to the axes of rotation of the nut 12 and the gear wheel 30 and allow threaded screws to penetrate the bores 16 and find their abutment in the threaded bores 17. In addition, the housing 15 has two fastening tabs 18 which, with bores 19, enable fastening screws 20 to be attached. As a result, the adapter 13 is securely fixed.
Die Mehrkantwelle liegt dadurch zumindest bereichsweise in der koaxial zur Mehrkantwelle 7 liegende Nuss 12, die dazu eine Mehrkantaufnahme besitzt. Die Nuss 12 ist drehbar, aber axial zumindest in Richtung des Handhebels 6 unverschiebbar in dem Gehäuse 15 gelagert. Das Gehäuse 15 ist entlang der Drehachse 21 der Mehrkantwelle 7 parallel zur Antriebsrichtung 22 versetzt befestigt.

Da nur axiale und radiale Kräfte aufgenommen werden müssen kann die Nuss 12 und ihre Lagerung sehr vereinfacht ausgeführt werden. Die Mehrkantwelle erhält zudem eine zweite axial versetzt liegende Lagerung, was die Anforderungen an die Bauteile weiter reduziert und das Zahnrad 30 der Antriebsvorrichtung 14 wirkungsvoll entlastet. Die Befestigung ist dadurch auch an The configuration described above allows the operating forces to be introduced into the nut 12, which is mounted independently of the drive device 14 in the housing 15 coaxially to the housing of the drive device. The nut 12 absorbs all axial and radial forces and does not take up any visible installation space. Since only axial and radial forces have to be absorbed, the nut 12 and its mounting can be made very simplified. The polygonal shaft is also given a second axially offset bearing, which further reduces the demands on the components and effectively relieves the load on the gear 30 of the drive device 14. The attachment is thereby also on
Ganzglasflügeln möglich, welche einen schmalen Isoliersteg hinter einer der Scheiben 2 aufweisen. All-glass leaves are possible, which have a narrow insulating web behind one of the panes 2.
Um die Rastungen zur Kennzeichnung der Funktionsstellungen zu realisieren ist vorgesehen, dass die Nuss 12 eine Rastausnehmungen 31 aufweist, welche die Nuss 12 in vier gleichmäßig verteilten Winkelstellungen in dem Gehäuse 15 drehfixiert. In dem Gehäuse 15 sind dazu Federn 32 in Taschen 33 befestigt, die mit Rastvorsprüngen in die Rastausnehmungen 31 eingreifen. Die Bohrung 34 in dem Gehäuse 15 ermöglicht der Zugriff auf die Madenschraube 24 im montierten Zustand. In order to realize the catches for identifying the functional positions, it is provided that the follower 12 has a catch recess 31 which fixes the follower 12 in four evenly distributed angular positions in the housing 15. For this purpose, springs 32 are fastened in pockets 33 in housing 15, said springs engaging with latching projections in latching recesses 31. The bore 34 in the housing 15 enables access to the grub screw 24 in the assembled state.
Der Adapter 13 kann abweichend von der Darstellung auch auf der abgewandten Seite der Antriebsvorrichtung 14 angeordnet werden. In a departure from the illustration, the adapter 13 can also be arranged on the opposite side of the drive device 14.
