Abstract

A control device is disclosed for selectively displacing two drive rod drivers which are coupled to drive rods of a window or door. The device includes a housing having a guide path defined therein for slidably receiving two drivers. The handle includes a turning member which is directly engaged with one driver and the device includes a clutch which is selectively engageable or disengageable between the two drivers so that, with rotation of the handle member, either both or one of the drivers may be moved along the guide path in the housing.

Description

Die Erfindung bezieht sich auf ein Getriebe zum Verschieben zweier Treibstangen eines Fenster- oder Türbeschlags mittels eines drehbaren Handgriffs od. dgl., wobei ein durch den Handgriff betätigbares Drehglied mit den Treibstangen verbunden ist. Derartige Getriebe sind im Fensterbau unter der Bezeichnung Baskülegetriebe bzw. -verschlüsse schon lange bekannt. Sie dienen zum gleichzeitigen Verschieben beider Treibstangen um dadurch den Flügel gegenüber dem festen Rahmen zu verriegeln bzw. freizugeben.The invention relates to a transmission for moving two drive rods of a window or door fitting by means of a rotatable handle or the like, wherein a rotary member which can be actuated by the handle is connected to the drive rods. Such gears have long been known in window construction under the name of baskets or locks. They are used to move both drive rods at the same time, thereby locking or releasing the sash relative to the fixed frame.

Es liegt die Aufgabe vor, ein derartiges Getriebe so weiterzubilden, daß im Bedarfsfalle lediglich eine der beiden Treibstangen verschoben wird.It is the task of developing such a transmission in such a way that only one of the two drive rods is moved if necessary.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß bei einem Getriebe gemäß dem Oberbegriff des Anspruchs 1 eine der Treibstangen unter Zwischenschaltung einer Kupplungsvorrichtung mit dem Drehglied verbunden ist. Bei eingerasteter Kupplungsvorrichtung bewirkt ein Drehen des Handgriffs die Verschiebung beider Treibstangen, während nach dem Auskuppeln lediglich noch eine Treibstange mit Hilfe des Handgriffs verschoben werden kann. Dieses Getriebe läßt sich infolgdessen überall dort einsetzen, wo ein Fenster- oder Türelement in wahlweise zwei Bedienungsstellungen gebracht werden soll. Es kann sich demnach beispielsweise um einen Drehkipp- oder einen Schiebekipp-Flügel handeln. über jede der beiden Treibstangen sind gewisse Elemente des Fenster- oder Türbeschlags eines derartigen Flügels zu betätigen, und es werden je nach Stellung der Kupplungsvorrichtung entweder sämtliche oder lediglich ein Teil der Elemente dieses Beschlags umgeschaltet, wenn man den Handgriff dreht.To achieve this object, it is proposed according to the invention that in a transmission according to the preamble of claim 1 one of the connecting rods is connected to the rotary element with the interposition of a coupling device. When the coupling device is engaged, turning the handle causes the displacement of both drive rods, while after disengaging, only one drive rod can still be moved using the handle. This gear can consequently be used wherever a window or door element is to be brought into two operating positions. Accordingly, it can be, for example, a turn-tilt or a slide-tilt wing. Certain elements of the window or door fitting of such a wing are to be actuated via each of the two connecting rods, and depending on the position of the coupling device, either all or only some of the elements of this fitting are switched over when the handle is turned.

Eine besonders bevorzugte Ausführungsform der Erfindung sieht vor, daß die Kupplungsvorrichtung zwei schiebbar im Getriebegehäuse gelagerte, je mit einer Treibstange verbindbare Kupplungsstücke aufweist, von denen das erste mit dem Drehglied in Arbeitsverbindung steht, und die je ein Kupplungselement tragen, von denen wenigstens eines ausrückbar ist. Die Kupplungsstücke dienen also zum Ankuppeln je einer Treibstange und sie sind nach dem Einbau des Getriebes damit in bevorzugter Weise immer verbunden. Jedes trägt ein Kupplungselement, mit deren Hilfe das An- und Abkuppeln der bewegungsmäßig abschaltbaren Treibstange möglich ist. Nachdem die beiden Kupplungsstücke über die Kupplungselemente zusammen- bzw. voneinander abkuppelbar sind, leuchtet es ohne weiteres ein, daß sich die Treibstangen dieses Getriebes bei einer Betätigung des Handgriffs nicht wie beim Baskülverschluß gegenläufig, sondern nur in gleichem Sinne bewegen können, d.h. beispielsweise beide nach oben oder nach unten, sofern die Kupplung eingerückt ist.A particularly preferred embodiment of the invention provides that the coupling device has two slidably mounted in the gear housing, each connectable to a drive rod Has coupling pieces, of which the first is in working connection with the rotary member, and each carry a coupling element, at least one of which can be disengaged. The coupling pieces are used to couple each drive rod and they are always connected to it in a preferred manner after installation of the transmission. Each carries a coupling element, with the help of which it is possible to connect and disconnect the drive rod which can be switched off in terms of movement. After the two coupling pieces can be uncoupled or uncoupled from one another via the coupling elements, it is readily apparent that the drive rods of this gearbox cannot move in opposite directions when the handle is actuated, as in the case of the cradle lock, but can only move in the same sense, that is, for example, both up or down if the clutch is engaged.

Bei einem Getriebe, bei dem lediglich eines der Kupplungselemente ausrückbar ist, wird in Weiterbildung der Erfindung vorgeschlagen, daß dieses ausrückbare Kupplungselement als gegen die Kraft einer Rückstellfeder am zweiten Kupplungsglied schwenkbar gelagerter, einarmiger Hebel ausgebildet ist. Wenn man auf dieses Kupplungselement beispielsweise mit Hilfe eines geeigneten Betätigungsorgans derart einwirkt, daß es gegen die Kraft seiner Rückstellfeder in eine wirksame Stellung verschwenkt wird, so führt das zu einem Ankuppeln der abkuppelbaren Treibstange unter der Voraussetzung, daß sich dabei das nicht ausrückbare Kupplungselement in der für das Ankuppeln richtigen Zuordnung befindet. Außerdem muß man durch geeignete Maßnahmen dafür Sorge tragen, daß die Rückstellfeder die Kupplungsvorrichtung nur dann wieder ausrückt, wenn dies erwünscht ist. Dies ist durch entsprechende Ausbildung des Betätigungsorgans für das ausrückbare Kupplungselement ohne weiteres zu erreichen.In a transmission in which only one of the clutch elements can be disengaged, it is proposed in a further development of the invention that this disengageable clutch element is designed as a one-armed lever pivotably mounted on the second clutch element against the force of a return spring. If one acts on this coupling element, for example with the aid of a suitable actuating member, in such a way that it is pivoted into an effective position against the force of its return spring, this leads to a coupling of the uncouplable drive rod, provided that the coupling element which cannot be disengaged is located in the for coupling correct assignment. In addition, appropriate measures must be taken to ensure that the return spring disengages the clutch device only when this is desired. This can be easily achieved by appropriate design of the actuating member for the disengageable coupling element.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß das ausrückbare Kupplungselement insbesondere an seinem freien Ende wenigstens ein Verrastglied trägt, das bei eingerückter Stellung in das eine Verrastaufnahme aufweisende Kupplungselement des ersten Kupplungsstücks eingreift. Verrastglied und Verrastaufnahme müssen so gestaltet sein, daß die Verrastung, d.h. das Ein- und Auskuppeln über eine einfache Schwenkbewegung möglich sind. Andererseits muß diese Verrastung jedoch so beschaffen sein, daß sie sich bei einer Verschiebung beider Treibstangen nicht lösen kann. Hierbei sieht eine weitere Variante der Erfindung vor, daß die Kupplungsstücke in ein und derselben Gehäuseführung schiebbar gelagert sind und bei eingerückter Kupplung aneinander anliegen. Für das Mitnehmen des abkuppelbaren Kupplungsstücks ist es zwar weder bei der Hin- noch bei der Herbewegung notwendig, daß die Kupplungsstücke bei eingerückter Kupplung in den beiden Schiebestellungen aneinander anliegen, jedoch führt das zu einer sehr kompakten Bauweise mit geringstem Raumbedarf, in Schieberichtung gesehen. Bei eingerückter Kupplung liegen die beiden Kupplungsstücke in jeder möglichen Schiebelage aneinander an. Bei ausgerückter Kupplung ist das nur in einer Schiebeendlage der Fall. Andererseits hat diese Ausbildung den Vorteil, daß man im Falle einer Fehlbedienung die vor dem Rückstellen abgekuppelte Treibstange über die Kupplungsstücke wieder zurückstellen kann.In a further embodiment of the invention it is provided that the disengageable coupling element carries in particular at its free end at least one latching element which engages in the engaged position in the coupling element of the first coupling piece which has a latching receptacle. Locking element and locking receptacle must be designed in such a way that the locking, ie engaging and disengaging, is possible via a simple swivel movement. On the other hand, however, this locking must be such that it cannot be released when both drive rods are moved. Here, a further variant of the invention provides that the coupling pieces are slidably mounted in one and the same housing guide and bear against one another when the clutch is engaged. In order to take the uncouplable coupling piece with you, it is not necessary either for the to-and-fro movement that the coupling pieces lie against one another in the two sliding positions when the clutch is engaged, but this leads to a very compact design with the smallest space requirement, viewed in the sliding direction. When the clutch is engaged, the two coupling pieces lie in each possible sliding position. With the clutch disengaged, this is only the case in a sliding end position. On the other hand, this design has the advantage that, in the event of incorrect operation, the drive rod uncoupled before resetting can be reset via the coupling pieces.

Das ausrückbare Kupplungselement wird, wie erläutert, gegen die Kraft einer Rückstellfeder in die Einkuppelstellung verschwenkt. Dann ist es verhältnismäßig einfach, dieses Kupplungselement bei stillstehenden Treibstangen mit Hilfe des Betätigungsorgans niederzuhalten, jedoch entfernt sich das ausrückbare Kupplungselement von seinem Betätigungsorgan, wenn man die Kupplungsstangen über den Handgriff verschiebt. Um nun ein Ausrücken der Kupplung während sowie am Ende der Verschiebebewegung zu verhindern, sieht eine bevorzugte Ausführungsform der Erfindung vor, daß das ausrückbare Kupplungselement in seiner eingerückten Stellung entlang einem Niederhalter verschiebbar ist, der insbesondere durch einen Gehäuseansatz od. dgl. gebildet ist. Bereits nach einer kurzen Längsverschiebung des ausrückbaren Kupplungselements tritt dieses unter den beispielsweise als Rippe ausgebildeten Gehäuseansatz, in dessen Bereich das ausrückbare Kupplungselement während seiner gesamten Verschiebung verbleiben kann. Erst wenn man es in seine Ausgangslage zurückschiebt, kommt es von dem Niederhalter frei und es kann, falls dies von seinem Beträtigungsorgan nicht verhindert wird, durch die Rückstellfeder in seine Ausgangslage zurückverschwenkt werden.As explained, the disengageable coupling element is pivoted into the engagement position against the force of a return spring. Then it is relatively easy to hold this coupling element down when the drive rods are stationary with the aid of the actuating member, but the disengageable coupling element moves away from its actuating member when the coupling rods are moved over the handle. In order to prevent disengagement of the clutch during and at the end of the displacement movement, a preferred embodiment of the invention provides that the disengageable coupling element can be displaced in its engaged position along a hold-down device, which is formed in particular by a housing attachment or the like. Already after a short longitudinal displacement of the disengageable coupling element, it comes under the housing attachment, which is designed, for example, as a rib, in the area of which the disengageable coupling element can remain during its entire displacement. Only when you push it back to its starting position does it come free from the hold-down device and it can, if this is not prevented by its actuating body will be pivoted back into its starting position by the return spring.

Das verrastbare Kupplungselement ist gemäß einer weiteren Ausgestaltung der Erfindung mittels eines insbesondere drehbaren Betätigungsorgans zumindest in seine eingerückte Stellung schwenkbar. Das Zurückführen besorgt die Rückstellfeder, so daß man hierzu die Mithilfe dieses Betätigungsorgans nicht benötigt. Das schließt natürlich nicht aus, daß man das Rückstellen trotzdem auch über das drehbare Betätigungsorgan oder eine weitere Vorrichtung besorgen oder zumindest unterstützen kann.According to a further embodiment of the invention, the latchable coupling element can be pivoted at least into its engaged position by means of a particularly rotatable actuating member. The return takes care of the return spring, so that you do not need the help of this actuator. Of course, this does not rule out that the resetting can still be carried out or at least supported via the rotatable actuating element or another device.

Bei einem Getriebe mit einem drehbaren Betätigungsorgan sieht eine Weiterbildung der Erfindung vor, daß letzteres ein exzentrisch zu seiner Drehachse angeordnetes Druckstück aufweist und zwischen das Druckstück und das ausrückbare Kupplungselement ein schwenk- und/oder federnd biegbares übertragungsglied geschaltet ist. Letzteres ermöglicht in einfacher Weise, die Drehbewegung des Betätigungsorgans in eine Schwenkbewegung umzusetzen, mit deren Hilfs das Kupplungselement in seine eingerückte Stellung bringbar ist. Die Schwenkbewegung des Übertragungsglieds erreicht man dadurch, daß sich das Druckstück des Betätigungsorgans bei der Drehung des letzteren von der Anlenkachse des biegbaren Übertragungsglieds mehr oder weniger stark entfernt und damit dessen Schräglage verstärkt oder abschwächt. Aus Platzgründen einerseits und auch zur Einsparung einer separaten Rückstellfeder für das Übertragungsglied ist es von besonderem Vorteil, daß das Übertragungsglied in der Art einer Blattfeder ausgebildet ist, deren freies Ende etwa parallel zum ausrückbaren Kupplungselement schwenkbar sowie an letzterem anliegt oder anlegbar ist, wobei das Übertragungsglied bei ausgerücktem Kupplungsglied zumindest weitgehend spannungsfrei und sein vom ausrückbaren Kupplungselement entferntes Ende am Gehäuse gehalten ist. Um mit einer verhältnismäßig kleinen, insbesondere einen Winkel von 90 Grad umfassenden Drehbewegung des Betätigungsorgans eine möglichst starke Verschwenkung des Kupplungselements zu bewirken, wird in weiterer Ausbildung der Erfindung vorgeschlagen, daß das Druckstück in seiner, dem festgehaltenen Ende des übertragungsglieds zugekehrten Drehlage in eine Rastvertiefung oder -ausnehmung des Übertragungsglieds eingreift. Zweckmäßigerweise haben die Rastvertiefung oder -ausnehmung und das Druckstück gleiche oder ähnliche Querschnittsformen. Insbesondere ist aber vorgesehen, daß die Rastvertiefung ein runder Durchbruch und das Druckstück ein Kegel oder Kegelstumpf ist. Aufgrund seiner geneigten Mantelfläche läuft der Kegel oder Kegelstumpf leicht aus der Rastvertiefung heraus bzw. in diese hinein, wobei im Hinblick auf die Weiterdrehung dem Kegelstumpf der Vorzug zu geben ist. Dieser reicht im übrigen vollkommen aus, um die Verschwenkung des Übertragungsglieds allein und ausreichend zu bewirken. Das bedeutet, daß es dabei auf den unterschiedlichen Abstand des Druckstücks von der Anlenkachse des Übertragungsglieds in seinen beiden Drehendlagen nicht oder zumindest nicht entscheidend ankommt, so daß man insoweit konstruktiv nicht gebunden ist. Insbesondere ist es möglich, das Druckstück auf einem vergleichsweise kleinen Radius zu bewegen, d.h. das Getriebe in diesem Bereich sehr kompakt auszubilden.In a transmission with a rotatable actuator, a development of the invention provides that the latter has an eccentrically arranged to its axis of rotation pressure piece and a pivotable and / or resiliently bendable transmission element is connected between the pressure piece and the disengageable coupling element. The latter makes it possible in a simple manner to convert the rotary movement of the actuating member into a pivoting movement, with the aid of which the coupling element can be brought into its engaged position. The pivoting movement of the transmission element is achieved in that the pressure piece of the actuating member moves more or less strongly from the articulation axis of the bendable transmission element during the rotation of the latter and thus reinforces or weakens its inclined position. For space reasons on the one hand and also for saving a separate return spring for the transmission member, it is particularly advantageous that the transmission member is designed in the manner of a leaf spring, the free end of which can be pivoted approximately parallel to the disengageable coupling element and abuts or can be applied to the latter, the transmission member being at least largely stress-free and when the coupling member is disengaged its end remote from the disengageable coupling element is held on the housing. In order to effect the greatest possible pivoting of the coupling element with a relatively small, in particular an angle of 90 degrees, rotary motion of the actuating element, it is proposed in a further embodiment of the invention that the pressure piece in its rotational position facing the fixed end of the transmission member into a recess or - recess of the transmission member engages. The latching recess or recess and the pressure piece expediently have the same or similar cross-sectional shapes. In particular, it is provided that the locking recess is a round opening and the pressure piece is a cone or truncated cone. Because of its inclined lateral surface, the cone or truncated cone easily runs out of or into the detent recess, preference being given to the truncated cone with regard to the further rotation. This is completely sufficient to effect the pivoting of the transmission link alone and sufficiently. This means that it depends on the different distance of the pressure piece from the articulation axis of the transmission element its two rotary end positions do not arrive, or at least not decisively, so that one is not bound constructively. In particular, it is possible to move the pressure piece over a comparatively small radius, that is to say to make the gearbox very compact in this area.

Eine andere Ausführungsform der Erfindung sieht vor, daß das erste Kupplungsstück an seinem gegen das zweite Kupplungsstück gerichteten Ende wenigstens ein keilartiges Steuerelement aufweist, das mit dem zugeordneten Verrastglied eine Rückstellvorrichtung für das ausrückbare Kupplungselement bildet. Diese Rückstellvorrichtung tritt dann in Kraft, wenn entweder die Rückstellfeder aufgrund eines Federbruchs ausfällt ode wenn das ausrückbare Kupplungselement in seine eingekuppelte Stellung verschwenkt wurde, ohne daß sich das andere Kupplungselement in einer für das Ankuppeln geeigneten Lage, d.h. der Ausgangslage des Getriebes, befunden hat. Wenn man in einem solchen Fall das mit dem Drehglied unmittelbar verbundene Kupplungsstück zurückstellt, so wird über das oder die Steuerelemente das Kupplungselement in seine ausgerückte Stellung zumindest so weit und so lange zurückgeführt, bis beide Kupplungsstücke wieder die für das Einrücken der Kupplung vorgesehene gegenseitige Lage eingenommen haben. Wenn also am Betätigungsorgan für die Kupplungsvorrichtung nichts verändert wird, so findet das Ankuppeln am Ende der Rückstellbewegung des mit dem Drehglied unmittelbar gekuppelten Kupplungsstücks automatisch statt. Vorteilhafterweise kann man dabei das rückwärtige Ende jedes Steuerelements zur Bildung der Verrastaufnahme heranziehen. Auf diese Weise ist das Getriebe besonders bedienungssicher.Another embodiment of the invention provides that the first coupling piece has at least one wedge-like control element at its end directed towards the second coupling piece, which forms a reset device for the disengageable coupling element with the associated latching member. This reset device comes into force when either the return spring fails due to a spring break or when the disengageable coupling element has been pivoted into its engaged position without the other coupling element being in a position suitable for coupling, ie the starting position of the transmission. If, in such a case, the coupling piece directly connected to the rotary member is reset, the coupling element is returned to its disengaged position via the control element (s) at least so far and until both coupling pieces again assume the mutual position provided for engaging the clutch to have. If nothing is changed on the actuating element for the coupling device, the coupling takes place automatically at the end of the return movement of the coupling piece which is directly coupled to the rotary member. Advantageously, you can the rear end of each control use to form the snap-in receiver. In this way, the transmission is particularly safe to use.

Eine andere Variante der Erfindung sieht vor, daß die Rückstellfeder des ausrückbaren Kupplungselements als Blattfeder ausgebildet ist, deren eines Ende an diesem Kupplungselement insbesondere klemmend gehalten ist und deren aus der Ebene des Kupplungselements herausgebogenes Ende sich am Gehäuse, vorzugsweise an einem abnehmbaren Gehäuseboden abstützt. Auch dies führt zu einer kompakten, wenig störanfälligen und preiswert zu fertigenden Konstruktion.Another variant of the invention provides that the return spring of the disengageable coupling element is designed as a leaf spring, one end of which is held in a particularly clamping manner on this coupling element and the end which is bent out of the plane of the coupling element is supported on the housing, preferably on a removable housing base. This also leads to a compact, less prone to failure and inexpensive to manufacture.

Aus demselben Grunde ist es auch von Vorteil, daß das erste Kupplungsstück eine sich quer zu seiner Verschieberichtung erstreckende Steuernut aufweist, in die ein exzentrischer, insbesondere drehbar gelagerter Steuerzapfen des Drehglieds eingreift, und daß die beiden Kupplungsstücke identisch ausgebildet sind. Vor allen Dingen das letztgenannte Merkmal trägt aufgrund der Verdoppelung der Stückzahlen zu einer preiswerten Fertigung und einfachen Lagerhaltung bei.For the same reason, it is also advantageous that the first coupling piece has a control groove extending transversely to its direction of displacement, in which an eccentric, in particular rotatably mounted control pin of the rotary member engages, and that the two coupling pieces are of identical design. Above all, the latter feature contributes to inexpensive production and simple storage due to the doubling of the number of pieces.

Schließlich ist gemäß einer weiteren Ausführungsform der Erfindung vorgesehen, daß jedes Kupplungsstück einen sich senkrecht zu seiner Verschieberichtung erstreckenden, dornartigen Mitnehmer zum Eingreifen in eine Mitnehmeraufnahme der zugeordneten Treibstange trägt. Die Treibstangen lassen sich also mit diesem Getriebe in besonders einfacher Welse verbinden, indem man sie einfach auf den jeweils vorgesehenen Mitnehmer aufsteckt.Finally, according to a further embodiment of the invention, it is provided that each coupling piece carries a mandrel-like driver, which extends perpendicular to its direction of displacement, for engaging in a driver receptacle of the associated drive rod. The drive rods can therefore be used connect this gearbox in a particularly simple catfish by simply plugging it onto the respective driver.

In einem schalenartigen Gehäuse 1, dessen abnehmbarer Teil als Deckel 2 ausgebildet ist - in Fig. 3 ist dieser Deckel weggelassen - ist ein Handgriff 3 drehbar gelagert, wie man ihn üblicherweise für Hebe-Schiebetüren, Dreh-Kipptüren bzw. -fenster od. dgl. verwendet. Das innere Ende seines angelenkten Endes 4 ist drehfest mit einem Drehglied 5 verbunden. Es besteht aus einem einarmigen Hebel mit am freien Hebelende aufgesetztem, insbesondere um seine Längsachse frei drehbaren, in der Art eines Gleitsteins ausgebildeten Steuerzapfen 6, der in eine Steuernut 7 eines ersten Kupplungsstücks 8 eingreift. Dreht man den Handgriff 1, ausgehend von der in Fig. 2 gezeigten Stellung, um 180 Grad in die Drehstellung gemäß Fig. 4, so bewirkt die aus der Steuernut 7 und dem Steuerzapfen 6 bestehende Einrichtung eine Verschiebung des ersten Kupplungsstücks 8 in Pfeilrichtung 9. Im eingebauten Zustand ist ein dornartiger Mitnehmer 10 des ersten Kupplungsstücks 8 mit einer nicht gezeigten Treibstange gekuppelt, so daß diese bei der 180-Grad-Drehung des Handgriffs 3 ebenfalls in Richtung des Pfeils 9 verschoben wird. Die Drehbewegung wird z.B. dadurch begrenzt, daß wahlweise eine der beiden Längsflanken des Drehglieds 5 an der Innenfläche 11 des Gehäuses 1 zur Anlage kommt.In a shell-like housing 1, the removable part of which is designed as a cover 2 - this cover is omitted in FIG. 3 - a handle 3 is rotatably mounted, as is usually the case for lift-slide doors, turn-tilt doors or windows or the like used. The inner end of its articulated end 4 is rotatably connected to a rotary member 5. It consists of a one-armed lever with a control pin 6, which is attached to the free end of the lever and can be freely rotated about its longitudinal axis and is designed in the manner of a sliding block and engages in a control groove 7 of a first coupling piece 8. If the handle 1 is rotated from the position shown in FIG. 2 by 180 degrees into the rotary position according to FIG. 4, the device consisting of the control groove 7 and the control pin 6 causes the first coupling piece 8 to be displaced in the direction of the arrow 9. In the installed state, a mandrel-like driver 10 of the first coupling piece 8 is coupled to a drive rod, not shown, so that this is also displaced in the direction of arrow 9 when the handle 3 is rotated 180 degrees. The rotational movement is limited, for example, by the fact that either one of the two longitudinal flanks of the rotary member 5 comes to rest on the inner surface 11 of the housing 1.

Die Innenfläche 11 und eine dazu parallele Innenfläche 12 des Gehäuses 1 bilden zugleich eine Führung für das erste Kupplungsstück 8 sowie ein zweites Kupplungsstück 13. Beide sind identisch ausgebildet und so dimensioniert, daß sie in der einen Verschiebeendstellung an der Querkante 14 und in der anderen Verschiebeendstellung an der Querkante 15 des Gehäuses 1 anliegen. Außerdem können sie in den beiden Verschiebeendstellungen unmittelbar aneinander anliegen, wie dies die Fign. 3 und 5 ausweisen. Dies ist allerdings nicht grundsätzlich der 7all, wie Fig. 4 zeigt, vielmehr kann das erste Kupplungsstück 8 auch ohne das zweite Kupplungsstück 13 in Pfeilrichtung 9 verschoben werden, wodurch dann diese beiden Kupplungsstücke bzw. ihre Mitnehmer 10 und 16 einen maximalen Abstand haben, der im Falle der in den Fign. 2 und 5 gezeigtn Stellungen ein Minimum beträgt, vorzugsweise gleich Null ist. Der Mitnehmer 16 ist mit einer zweiten, ebenfalls nicht dargestellten Treibstange gekuppelt. Ob das zweite Kupplungsstück 13 die Bewegung des ersten Kupplungsstücks in Pfeilrichtung 9 mitmacht oder nicht, hängt ausschließlich davon ab, ob eine zwischen diese beiden Teile geschaltete Kupplung einer Kupplungsvorrichtung 17 ein- oder ausgerückt ist. Aus den vorstehenden Ausführungen ergibt sich jedoch eindeutig, daß diese beiden Treibstangen bei eingerückter Kupplung stets gleichzeitig und gleich schnell in Pfeilrichtung 9 oder in Gegenrichtung verschoben werden, wenn man den Handgriff von der einen in die andere Drehstellung bewegt.The inner surface 11 and a parallel inner surface 12 of the housing 1 also form a guide for the first coupling piece 8 and a second coupling piece 13. Both are of identical design and dimensioned so that they are in one displacement end position on the transverse edge 14 and in the other displacement end position rest on the transverse edge 15 of the housing 1. In addition, they can be in direct contact with one another in the two final displacement positions, as shown in FIGS. Identify 3 and 5. However, this is not fundamentally the case as shown in FIG. 4, rather the first coupling piece 8 can can also be moved without the second coupling piece 13 in the direction of arrow 9, as a result of which these two coupling pieces or their drivers 10 and 16 are at a maximum distance, which in the case of those shown in FIGS. 2 and 5 shown positions is a minimum, preferably equal to zero. The driver 16 is coupled to a second drive rod, also not shown. Whether or not the second coupling piece 13 follows the movement of the first coupling piece in the direction of the arrow 9 depends exclusively on whether a coupling of a coupling device 17 connected between these two parts is engaged or disengaged. From the above statements, however, it is clear that these two connecting rods are always moved simultaneously and equally quickly in the direction of arrow 9 or in the opposite direction when the clutch is engaged, if the handle is moved from one rotary position to the other.

Das zweite Kupplungsstück 13 trägt ein ausrückbares Kupplungselement 18, das mit einem Kupplungselement 19 des ersten Kupplungsstücks 8 zusammenwirkt. Aufgrund einer bügelförmigen Rückstellfeder 20, deren freies, aus der Ebene des ausrückbaren Kupplungselements 18 herausragendes Ende sich an der Innenfläche des Deckels 2 abstützt, nimmt das ausrückbare Kupplungselement 18 normalerweise die aus Fig. 2 ersichtliche, gekippte Stellung ein. Im übrigen besitzt es eine angeformte Drehachse 22, deren zapfenförmige Enden je in eine Lagerhalbpchale 23 bzw.The second coupling piece 13 carries a disengageable coupling element 18 which interacts with a coupling element 19 of the first coupling piece 8. Owing to a bow-shaped return spring 20, the free end of which protrudes from the plane of the disengageable coupling element 18 is supported on the inner surface of the cover 2, the disengageable coupling element 18 normally assumes the tilted position shown in FIG. 2. Otherwise, it has an integrally formed axis of rotation 22, the peg-shaped ends of which are each in a half-shell 23 or

24 des zweiten Kupplungsstücks 13 eingreifen. Im übrigen ist das ausrückbare Kupplungselement 18 zwischen den beiden Schenkeln 25 und 26 bzw. 27 und 28 des zweiten Kupplungsstücks 13 bzw. des ersten Kupplungsstücks 8 in Richtung des Doppelpfeils 29 verschwenkbar.Daraus ergibt sich zugleich, daß die beiden Kupplungsstücke 8 und 13 spiegelbildlich in die Führung des Gehäuses 1 eingesetzt sind.24 engage the second coupling piece 13. Otherwise, the disengageable coupling element 18 can be pivoted between the two legs 25 and 26 or 27 and 28 of the second coupling piece 13 or the first coupling piece 8 in the direction of the double arrow 29. This also means that the two coupling pieces 8 and 13 are mirror images in the leadership of the housing 1 are used.

An seinem von der Drehachse 22 abgewandten Ende ist das ausrückbare Kupplungselement 18 T-förmig gestaltet. In seiner in Fig. 5 gezeigten Drehstellung greifen die freien T- Schenkelenden in einen Querschlitz 30 des ersten Kupplungsstücks 8 ein, der das feststehende Kupplungselement 19 bildet, wenn man von der Verschiebebewegung in Richtung des Doppelpfeils 31 absieht. Demnach stellen also die freien T- Schenkelenden Verrastglieder 32 und die beiden Enden des Querschlitzes 30 Verrastaufnahmen 33 dar.At its end facing away from the axis of rotation 22, the disengageable coupling element 18 is T-shaped. In its rotational position shown in FIG. 5, the free T-leg ends engage in a transverse slot 30 of the first coupling piece 8, which forms the fixed coupling element 19, if one disregards the displacement movement in the direction of the double arrow 31. Accordingly, the free T-leg ends are latching members 32 and the two ends of the transverse slot 30 are latching receptacles 33.

Weil die Rückstellfeder 20 das ausrückbare Kupplungselement 18 in einer gegenüber der Verschiebeebene geneigten Ebene hält, greifen die Verrastglieder 32 normalerweise nicht in die Verrastaufnahmen 33 ein. Das Einrücken der Kupplungsvorrichtung 17 erreicht man mit Hilfe eines drehbaren Betätigungsorgans 34, das in bevorzugter Weise als Knebel ausgebildet und um insbesondere 90 Grad drehbar ist. Exzentrisch zu dessen Drehachse 35 (Fig. 5) trägt es ein Druckstück 36, welches mit einer Rastausnehmung 37 eines Übertragungsglieds 38 zusammenwirkt. Beim Übertragungsglied 38 handelt es sich um ein vorzugsweise als Blattfeder ausgebildetes Element, dessen der Querkante 15 zugekehrtes Ende 39 am Gehäuse befestigt, beispielsweise angenietet ist. Die Rastausnehmung 37 ist in bevorzugter Weise ein kreisförmiger Durchbruch, und das Druckstück 36 hat die Gestalt eines Kegelstumpfs. Dreht man das Betätigungsorgan 34, ausgehend von der in Fig. 4 gezeigten Stellung, um 90 Grad in die aus Fig. 5 ersichtliche Lage, so tritt das Druckstück 36 aus der Rastausnehmung 37 aus und legt sich an der zugekehrten Flachseite des Übertragungsglieds 38 an. Diese beult sich infolgedessen unter gleichzeitiger elastischer Verformung aus, und ihr freies Ende drückt das freie Ende des ausrückbaren Kupplungselements 18 im Sinne des Pfeils 40 gegen den Widerstand der Rückstellfeder 20 nieder. Dadurch wird die Kupplung der Kupplungsvorrichtung 17 eingerückt. Wenn man nunmehr den Handgriff 3 von der in Fig. 2 gezeigten Stellung in die gemäß Fig. 5 überführt, so wird, im Gegensatz zu Fig. 4, das zweite Kupplungsstück 13 im Sinne des Pfeils 9 mitgenommen, wodurch dann beide Treibstangen diese Bewegung mitmachen. Weil sich bei dieser Verschiebung das ausrückbare Kupplungselement 18 allmählich vom freien Ende des Übertragungsglieds 38 entfernt, muß man durch eine geeignete Maßnahme dafür sorgen, daß sich die Kraft der Rückstellfeder 20 nicht im Sinne eines Ausrückens der Kupplung auswirken kann. Zu diesem Zweck besitzt das Gehäuse einen rippenförmigen Gehäuseansatz, der als Niederhalter 41 für das verschwenkte Kupplungselement 18 dient. Letzteres tritt bereits nach einer kurzen Verschiebebewegung der verschiebbaren Teile im Sinne des Pfeils 9 unter diesen Niederhalter 41 und verbleibt darunter entweder bis zum Erreichen der Verschiebeendstellung oder zumindest so lange, bis ein anderes Teil des Getriebes das Niederhalten bewirkt. Beim Ausführungsbeispiel ist die zweite Variante vorgesehen, und man erkennt beispielsweise in Fig. 5, daß in der "oberen" Verschiebeendstellung das Drehglied 5 ein Zurückschwenken des ausrückbaren Kupplungselements 18 entgegen dem Pfeil 40 und damit ein öffnen der Kupplung verhindert.Because the return spring 20 holds the disengageable coupling element 18 in a plane inclined with respect to the displacement plane, the latching members 32 normally do not engage in the latching receptacles 33. The engagement of the clutch device 17 is achieved with the aid of a rotatable actuating member 34, which is preferably designed as a toggle and can be rotated in particular by 90 degrees. Eccentric to the axis of rotation 35 (FIG. 5), it carries a pressure piece 36, which with a Locking recess 37 of a transmission member 38 cooperates. The transmission member 38 is an element which is preferably designed as a leaf spring and whose end 39 facing the transverse edge 15 is fastened, for example riveted, to the housing. The latching recess 37 is preferably a circular opening, and the pressure piece 36 has the shape of a truncated cone. If the actuating member 34 is rotated from the position shown in FIG. 4 by 90 degrees into the position shown in FIG. 5, the pressure piece 36 emerges from the latching recess 37 and rests on the flat side of the transmission member 38 which faces towards it. This consequently bulges out under simultaneous elastic deformation, and its free end presses down the free end of the disengageable coupling element 18 in the direction of arrow 40 against the resistance of the return spring 20. As a result, the clutch of the clutch device 17 is engaged. If the handle 3 is now transferred from the position shown in FIG. 2 to that shown in FIG. 5, in contrast to FIG. 4, the second coupling piece 13 is taken along in the direction of the arrow 9, as a result of which both drive rods then participate in this movement . Because with this displacement the disengageable coupling element 18 gradually moves away from the free end of the transmission member 38, one must take suitable measures to ensure that the force of the return spring 20 cannot have the effect of disengaging the clutch. For this purpose, the housing has a rib-shaped housing attachment, which acts as a hold-down device 41 the pivoted coupling element 18 is used. The latter occurs after a short displacement movement of the displaceable parts in the direction of arrow 9 under this hold-down device 41 and remains underneath it either until the displacement end position has been reached or at least until another part of the transmission causes the hold-down device. In the exemplary embodiment, the second variant is provided, and it can be seen, for example, in FIG. 5 that in the "upper" displacement end position, the rotary member 5 prevents the disengageable coupling element 18 from pivoting back against the arrow 40 and thus preventing the clutch from opening.

Das erste Kupplungsstück 8 bzw. wegen der identischen Ausbildung der Kupplungsstücke 8 und 13 beide Kupplungsstücke, tragen zwei in seitlichem Abstand voneinander angeordnete, keilartige Steuerelemente 42, die, wie nachfolgend noch erläutert wird, mit den zapfenförmigen Verrastgliedern 32 des ausrückbaren Kupplungselements 18 zusammenwirken können und deren seitlicher Abstand infolgedessen demjenigen der beiden Verrastglieder 32 entspricht. Außerdem wird noch darauf hingewiesen, daß das andere Ende 43 der bügelförmigen Rückstellfeder 20 klemmend in einer nutförmigen Aufnahme des ausrückbaren Kupplungselements 18 gehalten ist.The first coupling piece 8 or, because of the identical design of the coupling pieces 8 and 13, both coupling pieces, carry two wedge-like control elements 42 arranged at a lateral distance from one another, which, as will be explained in the following, can interact with the peg-shaped latching members 32 of the disengageable coupling element 18 and whose lateral distance consequently corresponds to that of the two latching members 32. In addition, it is pointed out that the other end 43 of the bow-shaped return spring 20 is held clamped in a groove-shaped receptacle of the disengageable coupling element 18.

Das vorstehend beschriebene Getriebe ist nicht nur von beders einfacher Bauart, sondern insofern auch sehr robust und zuverlässig, als Fehlbedienungen in jeder Stellung des Handgriffs 3 und des drehbaren Betätigungsorgans 34 ausgeschlossen bzw. unschädlich sind. Geht man von der in Fig. 2 gezeigtn Ausgangsstellung des Handgriffs 3 und des Betätigungsorgans 34 aus, so bewirkt eine Drehung des Handgriffs 3 um 180 Grad - oder gegebenenfalls auch einen anderen, insbesondere kleineren Drehwinkel - eine Verschiebung des Mitnehmers 10 von der in Fig. 2 gezeigten Stellung in diejenige gemäß Fig. 4. Da sich die Kupplungsvorrichtung 17 in einer wirkungslosen Stellung befindet, kann der Mitnehmer 16 diese Verschiebebewegung nicht mitmachen, d.h. es findet lediglich eine Verschiebung der mit dem Mitnehmer 10 gekuppelten Treibstange statt, während die mit dem Mitnehmer 16 gekuppelte Treibstange ihre Lage unverändert beibehält. Dreht man vor der erwähnten Verstellung des Handgriffs 3 das Betätigungsorgan 34 um seinen vorgesehenen Drehwinkel von vorzugsweise 90 Grad, so wird die Kupplung der Kupplungsvorrichtung 17 eingerückt, und nunmehr bewegen sich beide Treibstangen miteinander in Hin- und in Herrichtung.The transmission described above is not only of simple design, but is also very robust and reliable, as incorrect operations in any position of the handle 3 and the rotatable actuating member 34 are excluded or harmless. Judging from the gezeigtn in Figure 2 starting position of the handle 3 and the actuating member 34, so causing rotation of the handle 3 to 18 0 degree -. Or optionally a different, in particular smaller angle of rotation - a displacement of the tappet 10 from that in Fig 2. Since the coupling device 17 is in an ineffective position, the driver 16 cannot take part in this displacement movement, ie there is only a displacement of the drive rod coupled to the driver 10, while that with the Driver 16 coupled drive rod maintains its position unchanged. If, before the aforementioned adjustment of the handle 3, the actuating member 34 is rotated by its intended rotation angle of preferably 90 degrees, the coupling of the coupling device 17 is engaged, and now both drive rods move back and forth with one another.

Wenn man, ausgehend von der in Fig. 5 gezeigten Stellung, das drehbare Betätigungsorgan 34 wieder in seine Ausgangsstellung gemäß Fig. 2 zurückdreht und nachfolgend auch den Handgriff 3 wieder in die aus Fig. 2 ersichtliche Drehstellung bringt, so ist das deshalb ohne nachteilige Auswirkung, weil sich der Wegfall der Federkraft des Übertragungsglieds 38 und die Kraft der Rückstellfeder 20 so lange nicht auswirken können, bis der Niederhalter 41 das ausrückbare Kupplungselement 18 freigibt. Dies ist aber erst der Fall, wenn die Ausgangslage wieder erreicht ist.If, starting from the position shown in FIG. 5, the rotatable actuating member 34 is turned back into its starting position according to FIG. 2 and subsequently the handle 3 is again brought into the rotary position shown in FIG. 2, this is therefore without disadvantageous effect , because the loss of the spring force of the transmission member 38 and the force of the return spring 20 can not affect until the Hold-down device 41 releases the disengageable coupling element 18. However, this is only the case when the starting position is reached again.

Des weiteren ist es möglich, ausgehend von der in Fig. 4 gezeigten Lage der beiden Drehgriffe bzw. Kupplungsstücke 8 und 13, das drehbare Betätigungsorgan 34 in die Stellung gemäß Fig. 5 zu bringen. Wenn man daraufhin den Handgriff 3 wieder in die Ausgangslage gemäß Fig. 2 zurückdreht, so drücken die beiden Steuerelemente 42 das zweite Kupplungsstück 13 von der in Fig. 5 gezeigten Lage in die gemäß Fig. 2, und zwar gegen den Widerstand der Federkraft des Übertragungsglieds 38. Wenn die Verrastglieder 32 auf Höhe der Kupplungselemente 29 angekommen sind, kann sich die Federkraft des Übertragungs glieds 38 auswirken, weil numehr die Steuerelemente 42 vollständig an den Verrastgliedern 32 vorbeibewegt worden sind. Aus dem Vorstehenden wird ohne weiteres klar, daß man das drehbare Betätigungsorgan 34 sogar in jeder beliebigen Drehstellung des Handgriffs 3 drehen kann, ohne nachteilige Auswirkungen für die Betätigung der Treibstangen oder die Teile des Getriebes.Furthermore, it is possible, starting from the position of the two rotary handles or coupling pieces 8 and 13 shown in FIG. 4, to bring the rotatable actuating member 34 into the position according to FIG. 5. If the handle 3 is then turned back into the starting position according to FIG. 2, the two control elements 42 press the second coupling piece 13 from the position shown in FIG. 5 into the position according to FIG. 2, namely against the resistance of the spring force of the transmission element 38. When the locking members 32 have arrived at the level of the coupling elements 29, the spring force of the transmission member 38 can have an effect because the control elements 42 have been completely moved past the locking members 32. From the foregoing, it is readily apparent that the rotatable actuator 34 can be rotated even in any rotational position of the handle 3 without adversely affecting the actuation of the drive rods or the parts of the transmission.
