Description

Die Erfindung betrifft einen Bedienungsgriff mit einem zur formschlüssigen Kupplung mit einem Antriebselement, wie einem Ritzel eines Kantengetriebes dienenden Dorn, der nahe seinem freien Ende mit einem in einer Bohrung des Dorns federnd gelagerten Rastzapfen versehen ist, der aus einem Schaft, einem Bund und einem Rastkopf besteht, wobei der Schaft koaxial angeordnet ist zu einer zwischen dem Grund der Bohrung und dem Bund angeordneten Druckfeder und der Bund durch eine Verengung unverlierbar am Dorn gehalten ist und der über die Oberfläche des Dorns ragende Rastkopf mit einer zur hintergreifenden Anlage am Antriebselement und damit zur axialen Lagensicherung des Dorns dienenden Rastfläche und einer dem freien Ende des Dorns zugewandten Einführschräge versehen ist, wie er aus der DE-OS 4 238 459 vorbekannt ist.The invention relates to an operating handle with a form-fitting coupling with a drive element, such as a pinion of an edge gear mandrel, which is provided near its free end with a spring-loaded locking pin in a bore of the mandrel, which consists of a shaft, a collar and a locking head there, the shaft is arranged coaxially to a compression spring arranged between the bottom of the bore and the collar and the collar is captively held on the mandrel by a constriction and the locking head protruding over the surface of the mandrel with engaging behind the drive element and thus for axial position securing of the mandrel serving latching surface and an insertion slope facing the free end of the mandrel is provided, as is known from DE-OS 4 238 459.

Derartige Bedienungsgriffe sind mit einem üblicherweise als Vierkantstift ausgebildeten Dorn versehen, der bei am Fenster oder der Tür montiertem Zustand form- und kraftschlüssig in einen Innenvierkant eines auf mindestens eine längsverschiebbare Treibstange einwirkenden Antriebsritzels eines Kantengetriebes, eines Treibstangenbeschlags oder in eine Nuß eines Schlosses eingreift. Insbesondere aus optischen Gründen ist man bestrebt, beim Bedienungsgriff die ansonsten übliche Rosette wegzulassen, welche auch der Befestigung des Bedienungsgriffs am Fenster oder der Tür dient. Die Rosette wird durch eine in einer Bohrung des Rahmens des Fensters oder der Tür eingelassene Lagerhülse zur Führung des Bedienungsgriffs ersetzt. Der Bedienungsgriff ist mit seinem Dorn voran der Lagerhülse und dem Antriebselement zuzuführen. Beim Auftreffen der Einführschräge des Rastzapfens auf das Antriebselement wird der Rastkopf zurückgedrückt, so daß der Vierkantstift den Innenvierkant des Antriebselements passieren kann. Nach dem Durchtritt durch den Innenvierkant wird zum einen die Eingriffstiefe durch ein Anschlagen des Halses des Bedienungsgriffs an der Lagerhülse begrenzt und zum anderen drückt eine Druckfeder den Rastzapfen wieder nach außen, so daß der Rastkopf mit seiner Rastfläche an der Rückseite des Antriebselements zur Anlage gelangt und damit eine Rückbewegung des Bedienungsgriffs in Axialrichtung des Dorns verhindert. Die Befestigung des Bedienungsgriffs am Fenster oder der Tür erfolgt somit schnell, einfach und ohne das Erfordernis eines Werkzeugs.Such operating handles are provided with a mandrel usually designed as a square pin which, when mounted on the window or the door, engages positively and non-positively in an inner square of a drive pinion of an edge gear, a drive rod fitting or a nut of a lock acting on at least one longitudinally displaceable drive rod. For optical reasons in particular, efforts are being made to omit the otherwise usual rosette from the operating handle, which also serves to fasten the operating handle to the window or door. The rosette is replaced by a bearing sleeve embedded in a hole in the frame of the window or door for guiding the operating handle. The operating handle is to be fed with its mandrel first to the bearing sleeve and the drive element. When the insertion bevel of the locking pin strikes the drive element, the locking head is pushed back, so that the square pin the inner square of the drive element can happen. After passing through the inner square, the engagement depth is limited on the one hand by striking the neck of the operating handle on the bearing sleeve and, on the other hand, a compression spring pushes the locking pin outwards again, so that the locking head with its locking surface on the back of the drive element comes to rest and thus preventing the operating handle from moving back in the axial direction of the mandrel. The control handle can be attached to the window or door quickly, easily and without the need for a tool.

Der Rastzapfen beim Gegenstand der DE-OS 4 238 459 ist unmittelbar in eine Bohrung des Dorns eingebracht und wird in dieser Bohrung mittels einer Verengung der Bohrung gehalten. Die Querschnittsverengung der Bohrung erfolgt durch eine Werkstoffverquetschung des Materials des Dorns, inbesondere durch eine beidseits des vorstehenden Rastkopfs des Rastzapfens parallel zum Dorn vorgenommene Verquetschung, so daß der Öffnungsquerschnitt der Bohrung im wesentlichen ellipsenförmig verformt wird und der Rastzapfen dadurch auch mehr oder weniger gegen Verdrehen gesichert ist. Die Herstellung der Verengung durch werkstoffverquetschung bei in die Bohrung eingesetztem und federbelastetem Rastzapfen erfordert eine erhebliche Sorgfalt. Insbesondere ist zu vermeiden , daß durch die Verquetschung die Gängigkeit des Rastzapfens beeinträchtigt oder gar vollständig verhindert wird. Auch müssen angesichts der beengten Raumverhältnisse die Abmessungen der Verquetschung genau eingehalten werden. Eine ungleiche Ausgestaltung der Stärke des durch die Verquetschung erzeugten Wulstes ist zur Verhinderung einer Schrägstellung des Rastzapfens zu vermeiden.The locking pin in the subject of DE-OS 4 238 459 is introduced directly into a bore of the mandrel and is held in this bore by means of a narrowing of the bore. The cross-sectional constriction of the bore is caused by a material squeeze of the material of the mandrel, in particular by a squeeze carried out on both sides of the projecting locking head of the locking pin parallel to the mandrel, so that the opening cross-section of the bore is deformed essentially elliptically and the locking pin is thereby more or less secured against twisting is. The production of the constriction by crushing the material with the spring-loaded locking pin inserted into the bore requires considerable care. In particular, it is to be avoided that the movement of the locking pin is impaired or even completely prevented by the squeezing. In view of the limited space, the dimensions of the pinch must also be strictly observed. An uneven configuration of the thickness of the bead produced by the squeezing should be avoided to prevent the locking pin from being inclined.

Es liegt die Aufgabe vor, bei einem derartigen Bedienungsgriff die Montage des Rastzapfens und seine Führung zu verbessern.It is the object to improve the assembly of the locking pin and its guidance in such an operating handle.

Diese Aufgabe wird bei einem gattungsgemäßen Bedienungsgriff dadurch gelöst, daß der Rastzapfen in einer in die Bohrung des Dorns eingebrachten Buchse gelagert ist, deren Boden im wesentlichen bündig mit der Oberfläche des Dorns angeordnet ist und daß der Rastkopf mit mindestens einer Abflachung versehen ist, wobei der Querschnitt der Öffnung im Boden der Buchse an den unrunden Querschnitt des Rastkopfs angepaßt ist. In die Bohrung des Dorns wird nunmehr eine den Rastzapfen und die Druckfeder beherbergende Buchse eingebracht. Die Buchse ist mindestens einseitig mit einem Boden abgeschlossen. Die Buchse ist so tief in die Bohrung eingelassen, daß der Boden der Buchse bündig mit der Oberfläche des Dorns ist, also im Anwendungsfall eines Vierkantstifts bündig mit einer der Vierkantflächen, oder daß er etwas gegenüber dieser Oberfläche zurückstehend ist, also tiefer in die Bohrung eingelassen. Die Führung des Rastzapfens erfolgt somit durch die Buchse, die mit genauen Maßen und Anlagekanten für den Bund des Rastzapfens hergestellt werden kann und beim Einbringen in die Bohrung des Dorns ihre Maßhaltigkeit beibehält. Der Rastkopf besitzt einen unrunden Querschnitt. An diesen Querschnitt ist die Öffnung im Boden der Buchse angepaßt und durch diesen Formschluß ist eine Sicherung gegen ein Verdrehen des Rastzapfens gegenüber der Buchse und dem Dorn gegeben. Beim Einbringen der Buchse in die Bohrung des Dorns ist auf die richtige Zuordnung der Rastfläche zu achten, was durch eine entsprechende Markierung an der Buchse und/oder am Dorn vereinfacht werden kann.This object is achieved with a generic operating handle in that the locking pin is mounted in a bushing introduced into the bore of the mandrel, the bottom of which is arranged essentially flush with the surface of the mandrel and that the locking head is provided with at least one flattened portion, the Cross section of the opening in the bottom of the socket is adapted to the non-circular cross section of the locking head. A bushing which accommodates the locking pin and the compression spring is now introduced into the bore of the mandrel. The socket is closed at least on one side with a bottom. The bushing is inserted so deeply into the bore that the bottom of the bushing is flush with the surface of the mandrel, i.e. in the case of a square pin flush with one of the square surfaces, or that it is slightly recessed from this surface, that is, it is recessed into the bore . The locking pin is thus guided through the bushing, which can be produced with precise dimensions and contact edges for the collar of the locking pin and which maintains its dimensional accuracy when introduced into the bore of the mandrel. The locking head has a non-circular cross-section. The opening in the bottom of the bushing is adapted to this cross-section, and this positive locking provides protection against rotation of the locking pin relative to the bushing and the mandrel. When inserting the bushing into the bore of the mandrel, care must be taken to ensure the correct assignment of the locking surface, which can be simplified by appropriate marking on the bushing and / or on the mandrel.

Das Einbringen der Buchse in die Bohrung des Dorns kann auf vielfältige Weise erfolgen, z. B. durch ein Eindrehen, insbesondere wenn die Buchse auf dem Außendurchmesser und die Bohrung mit Gewinde versehen sind.The bushing can be inserted into the bore of the mandrel in a variety of ways, e.g. B. by screwing, especially if the socket on the outer diameter and the bore are threaded.

Bevorzugt wird jedoch die Buchse als Einpreßbuchse ausgebildet, so daß die Buchse mittels eines Einpreßvorgangs oder mittels Einschlagen kraftschlüssig in der Bohrung befestigt ist, wobei der Außendurchmesser der Buchse mit Riffelungen und dergleichen versehen sein kann als Sicherung gegen ein Verdrehen der Buchse innerhalb der Bohrung und zur Verbesserung der Haltekraft der Buchse in der Bohrung des Dorns und zur gleichzeitigen Verminderung der Anforderungen an die Maßhaltigkeit.However, the socket is preferably designed as a press-in socket, so that the socket is non-positively fastened in the bore by means of a press-in process or by hammering in, the outer diameter of the socket being able to be provided with corrugations and the like as a safeguard against rotation of the socket within the bore and for Improvement of the holding force of the bush in the bore of the mandrel and at the same time reducing the requirements for dimensional accuracy.

Es ist günstig, auch das andere Ende der Buchse mit einem Abschlußdeckel auszubilden, der in montiertem Zustand dem Grund der Bohrung im Dorn benachbart ist, so daß Rastzapfen und Druckfeder unverlierbar in der Buchse angeordnet sind.It is favorable to also form the other end of the bushing with an end cover which, in the assembled state, is adjacent to the bottom of the bore in the mandrel, so that the locking pin and compression spring are captively arranged in the bushing.

Ganz besonders vorteilhaft ist es, die Buchse mit Deckel und Boden einteilig auszubilden und die Öffnung im Boden für den Rastkopf koaxial zu einem Durchbruch im Deckel auszurichten, wobei die Buchse als Fließpreßteil oder Spritzgußteil ausgebildet sein kann.It is very particularly advantageous to form the socket with cover and base in one piece and to align the opening in the base for the latching head coaxially with an opening in the cover, wherein the socket can be designed as an extruded part or an injection molded part.

Zur Erzielung einer flächigen Anlage zwischen dem Rastkopf und der Rückseite des Antriebselements bei gekuppeltem Bedienungsgriff, ausgehend von einem kreiszylindrischen Ausgangsmaterial für den Rastzapfen, ist es vorteilhaft, die der Handhabe des Bedienungsgriffs zugewandte Rastfläche des Rastzapfens durch eine Abfräsung eines Kreisabschnitts zu schaffen.In order to achieve a flat contact between the locking head and the rear of the drive element when the operating handle is coupled, starting from a circular-cylindrical starting material for the locking pin, it is advantageous to create the locking surface of the locking pin facing the handle by milling a circular section.

Um eine korrekte Zuordnung des Bedienungsgriffs zum Antriebselement zu erhalten, ist es zweckmäßig, den Dorn mit einem Vorsprung zu versehen und die Dornausnehmung im Antriebselement mit einer korrespondierenden Längsnut, so daß der Dorn nur bei korrekter Position der Handhabe des Bedienungsgriffs gegenüber dem Antriebselement in das Antriebselement einführbar und damit kuppelbar ist.In order to obtain a correct assignment of the control handle to the drive element, it is expedient to provide the mandrel with a projection and the mandrel recess in the drive element with a corresponding longitudinal groove, so that the mandrel only in the drive element when the handle of the control handle is correctly positioned relative to the drive element is insertable and can therefore be coupled.

Der Vorsprung kann in bevorzugter Weise aus einer aus dem Material des Dorns herausgedrückten Nase bestehen. Insbesondere ist es günstig, die Nase in Verlängerung der Bohrung aus derem Grund herauszupressen, so daß Nase und Rastzapfen in derselben Ebene angeordnet sind und aus entgegengesetzten Oberflächen des Dorns aus diesen herausragen.The projection can preferably consist of a nose pressed out of the material of the mandrel. In particular, it is expedient to press out the nose in the extension of the bore for this reason, so that the nose and locking pin are arranged in the same plane and protrude from the opposite surfaces of the mandrel.

Der Schaft des Rastzapfens kann von einer Druckfeder umgeben sein, wobei die Führung des Rastzapfens in der Buchse weitgehend vom Bund übernommen wird. Um diese Führung zu verbessern, weisen der Schaft und der Bund des Rastzapfens denselben Durchmesser auf und die Druckfeder ist in einer Höhlung des Schafts gelagert.The shaft of the locking pin can be surrounded by a compression spring, the guidance of the locking pin in the bush being largely taken over by the collar. To improve this guidance, the shaft and the collar of the locking pin have the same diameter and the compression spring is mounted in a hollow of the shaft.

Der Bedienungsgriff 1 besteht aus der Handhabe 2 und dem Handhabenhals 3 mit dem Lagerteil 4, in denen der als Vierkantstift mit einer Kantenlänge von 7 mm ausgebildete Dorn 5 befestigt ist. Nahe dem freien Ende 6 des Dorns 5 ist ein Rastzapfen 7 angeordnet.The operating handle 1 consists of the handle 2 and the handle neck 3 with the bearing part 4, in which the mandrel 5, which is designed as a square pin with an edge length of 7 mm, is fastened. A locking pin 7 is arranged near the free end 6 of the mandrel 5.

Im Falz des Rahmens eines Flügels 8 eines Fensters oder einer Tür ist ein Kantengetriebe mit einem Gehäuse 9 verdeckt eingelassen angeordnet, wobei das Gehäuse 9 ein Antriebsritzel als Antriebselement 10 zur längsverschiebbaren Betätigung einer oder mehreren Treibstangen beherbergt. Den Zugang zu der als Innenvierkant 11 ausgebildeten Dornausnehmung des Antriebselements 10 wird durch ein Durchgangsloch 12 einer drehfest im Rahmen des Flügels 8 eingebrachten Lagerhülse 13 geschaffen.In the fold of the frame of a wing 8 of a window or a door, an edge gear with a housing 9 is concealed, the housing 9 accommodating a drive pinion as a drive element 10 for the longitudinally displaceable actuation of one or more drive rods. Access to the mandrel recess of the drive element 10, which is designed as an inner square 11, is provided through a through hole 12 of a bearing sleeve 13 which is inserted in the frame 8 in a manner fixed against relative rotation.

Wie Fig. 2 zu entnehmen, besteht der Rastbolzen 7 aus dem Schaft 14, dem Bund 15 und dem Rastkopf 16 und ist unverlierbar in einer in einer Bohrung 17 des Dorns 5 eingepreßten Buchse 18 gelagert, die mit einem Abschlußdeckel 19 versehen ist und mit einem Boden 20, welcher mit der Oberfläche 21 des Dorns 5 bündig gehalten ist. Der Schaft 14 ist von einer Druckfeder 22 umgeben, die sich einerends am Abschlußdeckel 19 der Buchse 18 abstützt, andererseits an der Unterseite des Bundes 15 und damit den Rastzapfen 7 gegen den Boden 20 der Buchse 18 drückt. Der Rastkopf 16 ist mit einer dem freien Ende 6 des Dorns 5 zugewandten Einführschräge 23 und gegenüberliegend, also der Handhabe 2 benachbart, mit einer Abflachung 24 versehen zur Bildung der Rastfläche 25. An diesen unrunden Querschnitt des Rastkopfs 16 ist der Querschnitt der Öffnung 26 im Boden 20 der Buchse 18 angepaßt und damit ist der Rastzapfen 7 unverdrehbar in der Buchse 18 längsverschiebbar gelagert.As can be seen in FIG. 2, the locking pin 7 consists of the shaft 14, the collar 15 and the locking head 16 and is captively stored in a bush 18 pressed into a bore 17 of the mandrel 5, which is provided with an end cover 19 and with a Bottom 20, which is kept flush with the surface 21 of the mandrel 5. The shaft 14 is surrounded by a compression spring 22, which is supported at one end on the end cover 19 of the socket 18, on the other hand presses against the bottom 20 of the collar 15 and thus the locking pin 7 against the bottom 20 of the socket 18. The locking head 16 is provided with an insertion bevel 23 facing the free end 6 of the mandrel 5 and opposite, i.e. adjacent to the handle 2, with a flattened portion 24 to form the locking surface 25. The cross-section of the opening 26 in this non-circular cross-section of the locking head 16 Bottom 20 adapted to the socket 18 and thus the locking pin 7 is non-rotatably mounted in the socket 18 longitudinally.

In Verlängerung der Bohrung 17 zur Aufnahme der Buchse 18 ist aus dem Material des Dorns 5 aus dem Grund 28 der Bohrung 17 ein Vorsprung in Form einer Nase 27 herausgeprägt und die als Innenvierkant ausgebildete Dornausnehmung 11 ist mit einer korrspondierenden Längsnut 29 versehen.In extension of the bore 17 for receiving the bushing 18, a projection in the form of a nose 27 is stamped out of the material of the mandrel 5 from the bottom 28 of the bore 17 and the mandrel recess 11, which is designed as an internal square, is provided with a corresponding longitudinal groove 29.

Zur Kupplung des Bedienungsgriffs 1 mit dem Antriebselement 10 wird der Bedienungsgriff 1, ausgehend von Fig. 1, mit dem Dorn 5 axial zugeführt, wobei der Dorn 5 sich durch das Durchgangsloch 12 der Lagerhülse 13 bewegt und mit der Einführschräge 23 gegen die Begrenzung der Dornausnehmung 11 stößt, und die Nase 27 zur Längsnut 29 der Dornausnehmung 11 ausgerichtet ist. Beim Weiterbewegen wird der Rastkopf 16 gegen Federkraft zurückgedrückt und steht nicht mehr über die Oberfläche 21 des Dorns 5 vor. Sobald der Rastkopf 16 durch die Dornausnehmung 11 des Antriebselements 10 hindurchgeschoben ist, bewirkt die Druckfeder 22 ein klickartiges Hervortreten des Rastkopfes 16 über die Oberfläche 21 des Dorns 5. Dann ist der Rastzapfen 7 mit seiner als Abflachung 24 ausgebildeten Rastfläche 25 an der Rückseite des Antriebselements 10 flächig anliegend angeordnet. Dies ist in Fig. 1 gestrichelt angedeutet. Gleichzeitig ist der Lagerteil 4 des Bedienungsgriffs 1 in dem Durchgangsloch 12 der Lagerhülse 13 drehbar gelagert unter Anlage des Handhabenhalses 3 an der Stirnfläche 30 der Lagerhülse 13. Somit ist der Bedienungsgriff 1 axialgesichert am Flügel 8 gehalten.To couple the control handle 1 to the drive element 10, the control handle 1, starting from FIG. 1, is fed axially with the mandrel 5, the mandrel 5 moving through the through hole 12 of the bearing sleeve 13 and with the insertion bevel 23 against the limitation of the mandrel recess 11 butts, and the nose 27 is aligned with the longitudinal groove 29 of the mandrel recess 11. When moving on, the locking head 16 is pressed back against spring force and no longer protrudes beyond the surface 21 of the mandrel 5. As soon as the locking head 16 is pushed through the mandrel recess 11 of the drive element 10, the compression spring 22 causes the click head 16 to protrude over the surface 21 of the mandrel 5 10 arranged flat. This is indicated by dashed lines in FIG. 1. At the same time, the bearing part 4 of the operating handle 1 is rotatably supported in the through hole 12 of the bearing sleeve 13, with the handle neck 3 resting against the end face 30 of the bearing sleeve 13. Thus, the operating handle 1 is held axially secured on the wing 8.

Zum Lösen des Bedienungsgriffs 1 ist der Rastkopf 16 mittels eines Werkzeugs gegen die Kraft der Druckfeder 22 zurückzudrücken. Dann kann der Bedienungsgriff 1 wieder gelöst und herausgezogen werden.To release the operating handle 1, the locking head 16 must be pressed back against the force of the compression spring 22 using a tool. Then the control handle 1 can be released and pulled out again.

Bei der Ausgestaltungsform gemäß Fig. 4 ist die in die Bohrung 17 des Dorns 5 eingepreßte Buchse 18' einteilig als Fließpreßteil mit Boden 20' und Deckel 19' ausgebildet. Die Öffnung 26 im Boden 20' der Buchse 18' zur Aufnahme des Rastkopfes 16 des Rastzapfens 7' und der Durchbruch 31 im Deckel 19' befinden sich auf derselben Achse. Schaft 14' und Bund 15' besitzen denselben Durchmesser und sind an den Innendurchmesser der Buchse 18' angepaßt. Es wird dadurch eine sichere, verkantungsfreie Führung des Rastzapfens 7' in der Buchse 18' gewährleistet. Die Druckfeder 22' ist dabei in einer zentrischen Höhlung 32 des Schafts 14' gelagert.4, the bushing 18 'pressed into the bore 17 of the mandrel 5 is formed in one piece as an extruded part with a base 20' and a cover 19 '. The opening 26 in the base 20 'of the socket 18' for receiving the locking head 16 of the locking pin 7 'and the opening 31 in the cover 19' are on the same axis. The shaft 14 'and collar 15' have the same diameter and are adapted to the inner diameter of the bushing 18 '. This makes it a safe, tilt-free guide of the locking pin 7 'guaranteed in the socket 18'. The compression spring 22 'is mounted in a central cavity 32 of the shaft 14'.
