Abstract

The invention makes provision for an actuating gear mechanism for fittings on windows, doors or the like, in the case of which two flat drive rods, located in one plane, can be adjusted synchronously and in opposite directions via a manual actuating element which can rotate about an axis. The effective length of the driver arm, which is coupled to the manual actuating element, is greater than the depth of a rebate groove into which the drive housing is introduced and in which the drive rods slide beneath a covering rail. By virtue of the large arm length, a large displacement path for the drive rods, along with limited rotary movement of the manual actuating element, is achieved in conjunction with the possibility of moving the driver arm in the end positions in each case into a dead-centre position, which locks the gear mechanism, with respect to said gear mechanism.

Description

Die Erfindung betrifft ein Betätigungsgetriebe für Beschläge an Fenstern, Türen oder dgl. mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an actuating gear for fittings on windows, doors or the like. With the features of the preamble of claim 1.

Solche Getriebe sind in verschiedenen Ausführungsformen bekannt und so ausgebildet, daß beim Drehen des Handbetätigungselementes die beiden Getriebestangen gleichzeitig und damit synchron in entgegengesetzten Richtungen oder gegenläufig verschoben werden. Die Getriebestangen übertragen diese Bewegung zu gleichen oder unterschiedlichen Zwecken an verschiedene Bereiche des betreffenden Rahmens. (Vgl. die EP-A-338621 bzw. die EP-A-501803).Such gears are known in various embodiments and are designed such that when the manual actuating element is rotated, the two gear rods are displaced simultaneously and thus synchronously in opposite directions or in opposite directions. The gear rods transmit this movement to different areas of the frame in question, for the same or different purposes. (See EP-A-338621 and EP-A-501803, respectively).

Die Betätigungsgetriebe werden verdeckt in eine zumeist genormte umlaufende Falznut des betreffenden Rahmens eingesetzt, und zwar so, daß das Betätigungsgetriebe in eine besondere Ausnehmung am Grunde der Nut eingeschoben wird, so daß die Getriebestangen in der Nut liegen, welche durch eine Abdeckschiene zum Falz hin abgedeckt ist. Die Deckschiene ist fest mit dem Rahmenteil verbunden. Bei den hier interessierenden bekannten Betätigungsgetrieben greift das Mitnehmerelement, das drehmäßig mit dem Handbetätigungselement verbunden ist, in eine der beiden Getriebestangen direkt ein um diese zu verschieben, wobei die Bewegung dieser Stange über ein ritzelförmiges Kupplungselement auf die andere Getriebestange übertragen wird. Bei den hier interessierenden bekannten Betätigungsgetrieben ist die Drehachse des ritzelförmigen Kupplungselementes senkrecht zur Ebene der Abdeckschiene oder senkrecht zur Drehachse des Handbetätigungselementes orientiert. Die Ritzelzahne weisen also zu den Seiten der Falznut. Das Mitnehmerelement ist dabei zahnradähnlich mit mehreren auf einem Teilkreis um die Drehachse angeordneten Mitnehmerzähnen ausgebildet und steht mit einem Zahnstangenabschnitt der einen Getriebestange in direktem Eingriff, welcher Zahnstangenabschnitt in unmittelbarer Nähe der Drehachse des Handbetätigungselementes und tangential zu dem Teilkreis des Mitnehmerzahnrades verläuft. In beiden Fällen ist der zur Übertragung der Verschiebebewegung am Mitnehmerelement zur Verfügung stehende Kraftarm vergleichsweise gering und entspricht nur einem Bruchteil der genormten Tiefe der Falznut. Dies bedeutet einerseits einen relativ hohen Kraftaufwand und andererseits ein ungünstiges Verhältnis zwischen Drehwinkel des Handbetätigungselementes und dem zugehörigen linearen Verstellweg der Getriebestangen. Wenn die genormte Breite der Falznut eingehalten werden soll, kann auch das ritzelförmige Kupplungselement nur relativ klein und damit schwach ausgebildet werden.The actuating gears are inserted in a mostly standardized circumferential groove of the frame in question, so that the actuating gear is inserted into a special recess at the bottom of the groove, so that the gear rods are in the groove, which is covered by a cover rail for the fold is. The cover rail is firmly connected to the frame part. In the known actuating gears of interest here, the driver element, which is rotationally connected to the manual actuating element, engages directly in one of the two gear rods in order to displace them, the movement of this rod being transmitted to the other gear rod via a pinion-shaped coupling element. In the known actuating gears of interest here, the axis of rotation of the pinion-shaped coupling element is oriented perpendicular to the plane of the cover rail or perpendicular to the axis of rotation of the manual actuating element. The pinion teeth thus point to the sides of the groove. The driver element is designed like a gearwheel with a plurality of driver teeth arranged on a pitch circle around the axis of rotation and is in direct engagement with a rack section of the one gear rack, which rack section runs in the immediate vicinity of the axis of rotation of the manual actuation element and tangential to the pitch circle of the driver gearwheel. In both cases, the force arm available for transmitting the displacement movement on the driver element is comparatively small and corresponds to only a fraction of the standardized depth of the rebate groove. On the one hand, this means a relatively high expenditure of force and, on the other hand, an unfavorable ratio between the angle of rotation of the manual actuation element and the associated linear adjustment path Gear rods. If the standardized width of the rebate groove is to be maintained, the pinion-shaped coupling element can also be made only relatively small and therefore weak.

Bei einem anderen bekannten Betätigungsgetriebe (EP-A-229 582) ist ein rechteckiger Getriebekasten vorgesehen, der nach außen durch eine die Falznut abdeckende Deckschiene abgedeckt ist, an deren Unterseite die flachen Getriebestangen geführt sind. An der Bodenseite des Gehäuses ist ein Getriebeglied in Form eines Zahnstangenabschnittes geführt. Mit einer der Getriebestangen und dem Getriebeglied ist ein Zahnritzel in Eingriff, das in dem Gehäuse parallel zu der Drehachse eines Handbetätigungselementes gelagert ist. Dieses weist einen Kurbelarm auf, der über eine Zapfen/Schlitzverbindung mit einem Kupplungsglied gekuppelt ist, welches mit der auch mit dem Ritzel in Eingriff stehenden Getriebestange antriebsmäßig verbunden ist. Die Drehachse des Handbetätigungselementes liegt, wie die des Ritzels, zwischen den Getriebestangen einerseits und dem Getriebeglied andererseits. Die wirksame Länge des Kurbelarmes entspricht somit etwa der Hälfte der Tiefe des Getriebekastens. Für einen ausreichenden Verschiebeweg der Getriebestangen muß der Getriebekasten und entsprechend die den Getriebekasten aufnehmende Ausnehmung des entsprechenden Rahmenelementes eine ausreichende Tiefe aufweisen.In another known actuating gear (EP-A-229 582) a rectangular gear box is provided, which is covered on the outside by a cover rail covering the rabbet groove, on the underside of which the flat gear rods are guided. A gear member in the form of a rack section is guided on the bottom side of the housing. A toothed pinion, which is mounted in the housing parallel to the axis of rotation of a manual control element, engages with one of the gear rods and the gear member. This has a crank arm which is coupled via a pin / slot connection to a coupling member which is drivingly connected to the gear rod which is also engaged with the pinion. The axis of rotation of the manual operating element, like that of the pinion, lies between the gear rods on the one hand and the gear member on the other. The effective length of the crank arm thus corresponds to approximately half the depth of the gear box. For a sufficient displacement path of the gear rods, the gear box and correspondingly the recess of the corresponding frame element receiving the gear box must have a sufficient depth.

Demgegenüber ist es Aufgabe der Erfindung, das Betätigungsgetriebe gemäß der EP-A-229582 mit den Merkmalen des Oberbegriffs des Anspruchs 1 so weiterzubilden, daß ein günstiges Verhältnis zwischen Drehwinkel des Handbetätigungselementes und dem entsprechenden Verschiebeweg der Getriebestangen und ein günstiges Kraftverhältnis erreicht werden, ohne daß eine gegenüber den genormten Abmessungen abweichende Falznut in die Rahmenteile eingearbeitet werden muß.In contrast, it is an object of the invention to develop the actuating gear according to EP-A-229582 with the features of the preamble of claim 1 so that a favorable relationship between the angle of rotation of the manual actuating element and the corresponding displacement path of the gear rods and a favorable force ratio can be achieved without a rebate groove that deviates from the standardized dimensions must be worked into the frame parts.

Erfindungsgemäß wird die genannte Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention, the stated object is achieved by the characterizing features of claim 1.

Die Erfindung ermöglicht es für die Verschiebung der Getriebestangen praktisch den vollen Abstand zwischen der Drehachse des Handbetätigungselementes und der Außenfläche der Abdeckschiene für die wirksame Länge des Kraftarmes am Mitnehmerelement auszuschöpfen. Dadurch ergibt sich eine günstige Ausnutzung der über das Handbetätigungselement aufgebrachten Verstellkraft. Ferner braucht man für das Mitnehmerelement nicht mehr eine zahnradartige Ausbildung mit mehreren Mitnehmerzähnen, um einen ausreichenden Verschiebewg zu erzielen. Es genügt vielmehr ein einziger kurbelarmartiger Mitnehmer. Dies bedeutet, daß das Gehäuse des Betätigungsgetriebes auf der von der Abdeckschiene abgewandten Seite der Drehachse kürzer oder flacher ausgebildet werden kann, so daß eine geringere Einbautiefe benötigt wird und das Betätigungsgetriebe auch bei schmalen Rahmenprofilen eingesetzt werden kann. Es ergibt sich ein außerordentlich günstiges Verhältnis zwischen Drehwinkel des Mitnehmers und Betätigungselementes und der Länge des Verschiebeweges der Getriebestangen. Dies Verhältnis ist so günstig, daß ein Teil des Schwenkwinkels des Handbetätigungselementes dazu ausgenutzt werden kann, um nach Erreichen der Endstellung des Verschiebeweges das Mitnehmerelement gegenüber den Getriebestangen in eine das Getriebe in den Endstellungen sperrende Totpunktlage zu verdrehen. Ferner kann das ritzelförmige Kupplungselement entsprechend kräftig ausgebildet werden, weil einmal für den Durchmesser des Kupplungselementes ein Großteil der Tiefe der Falznut zur Verfügung steht und die einzelnen Ritzelzähne eine große Länge aufweisen können.The invention makes it possible for the displacement of the gear rods to virtually exhaust the full distance between the axis of rotation of the manual actuation element and the outer surface of the cover rail for the effective length of the force arm on the driver element. This results in a favorable utilization of the adjustment force applied via the manual actuation element. Furthermore, a gear-like design with several driver teeth is no longer required for the driver element in order to achieve a sufficient displacement path. Rather, a single crank arm-like driver is sufficient. This means that the housing of the actuating gear can be made shorter or flatter on the side of the axis of rotation facing away from the cover rail, so that a smaller installation depth is required and the actuating gear can also be used with narrow frame profiles. The result is an extremely favorable ratio between the angle of rotation of the driver and the actuating element and the length of the displacement path of the gear rods. This ratio is so favorable that part of the pivoting angle of the manual actuating element can be used to turn the driver element relative to the gear rods into a dead center position blocking the gear in the end positions after reaching the end position of the displacement path. Furthermore, the pinion-shaped coupling element can be designed to be correspondingly strong because, once for the diameter of the coupling element, a large part of the depth of the rebate groove is available and the individual pinion teeth can have a great length.

Die erfindungsgemäße Ausbildung ermöglicht es, das Betätigungsgetriebe mit seinen Außenabmessungen so auszubilden, daß es in eine genormte Falznut sowohl der Breite nach als auch der Tiefe nach ohne Veränderungen der Falznut eingesetzt werden kann, mit Ausnahme der üblichen Vertiefungen zur Aufnahme der Drehachse des Betätigungselementes und der Gehäuseabschnitte, die zur Festlegung des Betätigunsgetriebes im Rahmen dienen.The design according to the invention makes it possible to design the actuating gear with its outer dimensions so that it can be used in a standardized groove both in width and in depth without changing the groove, with the exception of the usual recesses for receiving the axis of rotation of the actuating element and the Housing sections that serve to define the actuating gear in the frame.

Die Erfindung wird nachfolgend anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert.

The invention is explained in more detail below with the aid of schematic drawings using an exemplary embodiment.
Figure 1
shows the actuating gear according to the invention in an exploded perspective view.
Figure 2 and Figure 3
show the transmission in longitudinal section in one and in the other end position of the transmission rods.

Das Betätigugsgetriebe gemäß der Erfindung weist ein zweischaliges Getriebegehäuse 1a, 1b mit einem mittleren Ansatz und einer darin befindlichen Öffnung 2 auf, in die die seitlichen Lagerzapfen eines kurbelarmartigen Mitnehmerelementes 3 zur drehbaren Lagerung dieses Elementes eingreifen können. Das Mitnehmerelement weist eine Vierkantbohrung 4 zum Einstecken der Steckachse eines nicht gezeigten Handbetätigungselementen auf, dessen Drehachse mit 25 bezeichnet ist. Das Handbetätigungselement und der Mitnehmer sind auf diese Weise zu einer drehbaren Einheit gekuppelt. Das Mitnehmerelement 3 weist im dargestellten Beispiel einen radial vorspringenden Kurbel- oder Mitnehmerarm 5 auf, dessen freies Ende ein abgerundetes Profil aufweist.The actuating gear according to the invention has a two-shell gear housing 1a, 1b with a central shoulder and an opening 2 located therein, into which the lateral bearing journals of a crank arm-like driver element 3 can engage for the rotatable mounting of this element. The driver element has a square bore 4 for inserting the plug-in axis of a manual control element, not shown, whose axis of rotation is designated by 25. The manual control element and the driver are coupled in this way to form a rotatable unit. In the example shown, the driver element 3 has a radially projecting crank or driver arm 5, the free end of which has a rounded profile.

Das Gehäuse wird im Bereich einer nicht dargestellten Falznut des betreffenden Rahmenteils von der Falzseite her eingesetzt wozu in dem Rahmenteil im Bereich der Falznut eine Ausnehmung auf geeignete Weise, z.B. mit Hilfe eines Bohrersatzes eingearbeitet wird. Das Gehäuse ist so ausgebildet, daß sein langgestreckter Teil der Breite und der Höhe nach der Breite und Tiefe der Falznut entspricht, während der mittlere Ansatz und die beiden seitlichen Ansätze 30 in die zusätzlich eingearbeitete Ausnehmung eingreifen.The housing is inserted in the area of a notch groove of the frame part in question from the fold side, for which purpose a recess is machined in the frame part in the area of the groove groove in a suitable manner, for example with the aid of a drill set. The housing is designed so that its elongated part corresponds to the width and height according to the width and depth of the rebate groove, while the middle extension and the two lateral extensions 30 engage in the additionally machined recess.

Die Falznut wird nach außen durch eine übliche Abdeckschiene 6 abgedeckt, wobei die beiden Gehäusehälften 1a, 1b so ausgebildet sind, daß sie die Abdeckschiene 6 im Bereich von Randausnehmungen der Abdeckschiene übergreifen, wie dies aus den Figuren 2 und 3 hervorgeht.The rebate groove is covered on the outside by a conventional cover rail 6, the two housing halves 1a, 1b being designed such that they overlap the cover rail 6 in the region of edge recesses of the cover rail, as can be seen from FIGS. 2 and 3.

Direkt auf der Unterseite der Abdeckschiene 6 sind als Flachstangen ausgebildete Getriebestangen 7, 8 angeordnet, die im dargestellten Beispiel geradlinig ausgebildet sind und in einer gemeinsamen Ebene liegen. In einer Endstellung des Betätigungsgetriebes (Fig. 2) stoßen die Getriebestangen 7, 8 nahezu aneinander, während sie in der anderen Endstellung (Fig. 3) mit ihren Enden einen vorbestimmten, dem Stellweg entsprechenden Abstand aufweisen. Der maximale Stellweg jeder der beiden Stangen entspricht der Hälfte des aus Figur 3 ersichtlichen Abstandes.Directly on the underside of the cover rail 6 are arranged gear rods 7, 8 which are designed as flat rods and, in the example shown, are linear and lie in a common plane. In one end position of the actuating gear (FIG. 2), the gear rods 7, 8 almost abut one another, while in the other end position (FIG. 3) their ends are at a predetermined distance corresponding to the travel. The maximum travel of each of the two rods corresponds to half the distance shown in Figure 3.

Wie aus den Figuren 2 und 3 hervorgeht, weist das Mitnehmerelement 3 eine wirksame Kurbelarmlänge auf, die praktisch dem Abstand zwischen der Drehachse 25 und zumindestens der Außenfläche der Abdeckschiene 6 entspricht. Dies wird dadurch möglich, daß der Mitnehmer- oder Kurbelarm 5 des Mitnehmerelementes 3 durch entsprechende Schlitze oder Ausnehmungen der Getriebeteile hindurchragt und in die Eingriffsausnehmung 19 eines Eingriffselementes 14 eingreift. Dieses Eingriffselement weist einen Basisabschnitt 15 von größeren Abmessungen und schmälere Ansätze 16 auf. Wie aus den Figuren ersichtlich ist, greifen die Ansätze 16 zur Führung des Eingriffselementes 14 in einen Längsschlitz 18 der Abdeckschiene 6 ein, während der Basisabschnitt 15 auf der Unterseite der Abdeckschiene 6 aufliegt und zugleich frei in ein Fenster 17 der Getriebestange 7 eingreift. In Längsrichtung versetzt gegenüber dem Fenster 17 weist die Getriebestange 7 auf der nach innen weisenden Flachseite einen gezahnten Abschnitt 20 auf mit dem in ständigem Eingriff ein ritzelförmiges Kupplungselement 11 steht, das mit seinen Lagerzapfen 12 in Lagerbohrungen 13 der beiden Gehäusehälften 1a, 1b eingreift. Die Drehachse 26 des Kupplungselementes 11 verläuft parallel zur Drehachse 25 des Handbetätigungselementes. An der von der Abdeckschiene 6 abgewandten Seite des Gehäuses und damit am Grunde der Falznut ist ein langgestrecktes profiliertes Getriebeelemente 9 geführt, das einen Längsschlitz 10 aufweist, durch den in allen Stellungen des Getriebes der Mitnehmerarm 5 greift. Das Querschnittsprofil des Getriebeelementes 9 ist so gewählt, daß es eine ausreichende Steifigkeit aufweist und zugleich am innenliegenden Bereich des Gehäuses geführt ist. An einem Ende weist das Getriebeelement 9 einen gezahnten Abschnitt 21 auf, in den das Kupplungselement 11 zur Kupplung des Getriebeelementes 9 mit der Getriebestange 7 eingreift. Im Bereich des anderen Endes weist das Getriebeelement 9 Eingriffsabschnitte 22 auf, die in Randaussparungen 23 der anderen Getriebestange 8 eingreifen, so daß das Getriebeteil 9 und die Getriebestange 8 eine verschiebliche Einheit bilden.As can be seen from FIGS. 2 and 3, the driver element 3 has an effective crank arm length which practically corresponds to the distance between the axis of rotation 25 and at least the outer surface of the cover rail 6. This is possible because the driver or crank arm 5 of the driver element 3 projects through corresponding slots or recesses in the gear parts and engages in the engagement recess 19 of an engagement element 14. This engagement element has a base section 15 of larger dimensions and narrower lugs 16. As can be seen from the figures, the lugs 16 for guiding the engaging element 14 engage in a longitudinal slot 18 of the cover rail 6, while the base section 15 rests on the underside of the cover rail 6 and at the same time freely engages in a window 17 of the gear rod 7. In the longitudinal direction offset from the window 17, the gear rod 7 has a toothed section 20 on the inward-facing flat side with which a pinion-shaped coupling element 11 is in constant engagement, which engages with its bearing pin 12 in bearing bores 13 of the two housing halves 1a, 1b. The axis of rotation 26 of the coupling element 11 runs parallel to the axis of rotation 25 of the manual actuation element. On the side of the housing facing away from the cover rail 6 and thus at the base of the groove, an elongated profiled gear element 9 is guided, which has a longitudinal slot 10 through which the driving arm 5 engages in all positions of the gear. The cross-sectional profile of the gear element 9 is selected so that it has sufficient rigidity and at the same time on the inside Area of the housing is guided. At one end, the gear element 9 has a toothed section 21, in which the coupling element 11 engages for coupling the gear element 9 with the gear rod 7. In the area of the other end, the gear element 9 has engagement sections 22 which engage in edge recesses 23 of the other gear rod 8, so that the gear part 9 and the gear rod 8 form a displaceable unit.

Wie aus Figur 2 und 3 ersichtlich ist, sind das Eingriffselement 14 in das Fenster 17 und das Getriebeelement 9 in die Randausnehmungen 23 der Getriebestange 8 lose eingesetzt. Sie werden in dieser Stellung durch die Führung in dem Getriebegehäuse bzw. an der Abdeckschiene 6 zuverlässig gehalten.As can be seen from FIGS. 2 and 3, the engagement element 14 is loosely inserted into the window 17 and the gear element 9 into the edge recesses 23 of the gear rod 8. They are reliably held in this position by the guide in the gear housing or on the cover rail 6.

Die Figuren 2 und 3 zeigen jeweils die Endstellungen der Getriebestangen 7, 8 und des Mitnehmerelementes 3. Es ist ersichtlich, daß aufgrund der Ausbildung des Mitnehmerarmes 5 und des Eingriffselementes 14 die Getriebestangen 7 und 8 die in Figur 2 und 3 gezeigte Endstellung jeweils früher erreichen als das Mitnehmerelement 3 seine Winkelendstellung. Die zusätzliche Bewegung des Mitnehemrelementes 3 ohne Verschieben der Getriebestange dient dazu, das Mitnehmerelement gegenüber der profilierten Öffnung 24 des Eingriffselementes 14 in eine Totpunktlage zu bringen, die durch die gestrichelten Linien 27 und 28 wiedergegeben ist. Diese Linien gehen in den Endstellungen durch die Drehachse 25 des Handbetätigungselementes und fallen mit der Längsmittellinie des Mitnehmerarmes 5 zusammen und stehen jeweils senkrecht auf den Öffnungsflächen 24 des Eingriffselementes. Das bedeutet, daß in diesen Stellungen das Getriebe jeweils gesperrt ist. Zur Entsperrung steht jeweils ein bestimmter Leerweg für die Drehung des Mitnehmerelementes 3 zur Verfügung, wie dies aus den Figuren 2 und 3 ohne weiteres ersichtlich ist.Figures 2 and 3 each show the end positions of the gear rods 7, 8 and the driver element 3. It can be seen that due to the design of the driver arm 5 and the engaging element 14, the gear rods 7 and 8 each reach the end position shown in Figures 2 and 3 earlier than the driver element 3 its angular end position. The additional movement of the driving element 3 without moving the gear rod serves to bring the driving element in relation to the profiled opening 24 of the engaging element 14 into a dead center position, which is shown by the dashed lines 27 and 28. In the end positions, these lines pass through the axis of rotation 25 of the manual actuation element and coincide with the longitudinal center line of the driving arm 5 and are each perpendicular to the opening surfaces 24 of the engagement element. This means that the gear is locked in these positions. A specific free travel for the rotation of the driver element 3 is available for unlocking, as can be easily seen from FIGS. 2 and 3.

Das Getriebegehäuse ist auf der der Abdeckschiene 6 abgewandten Seite der Drehachse 25 bei 1b (Fig. 3) abgeflacht oder abgeschnitten, was die Eingriffstiefe des Gehäuses in die zusätzliche Ausnehmung des Rahmens verringert. Die große Länge des Kurbelarmes oder Mitnehmerarmes 5 wird dadurch nicht beeinträchtigt.The gear housing is flattened or cut off on the side of the axis of rotation 25 facing away from the cover rail 6 at 1b (FIG. 3), which reduces the depth of engagement of the housing in the additional recess of the frame. The large length of the crank arm or driver arm 5 is not affected.
