Description

Die Erfindung betrifft ein Stulphebelgetriebe zur wahlweisen Verriegelung oder Entriegelung eines unterschlagenen Flügels von zweiflügeligen Fenstern, Fenstertüren oder dergleichen mit einem Stulpschienenabschnitt und zumindest einen an dem Stulpschienenabschnitt längsverschieblich geführten Treibstangenabschnitt, mit einem Betätigungshebel, mit einem Lenker, mit einer Lagerung des Lenkers in einem mittleren Bereich an dem Betätigungshebel, mit einer Lagerung des zweiten Endes des Lenkers, mit einer Lagerung eines Endes des Betätigungshebels, wobei zumindest eine der Lagerungen des Betätigungshebels oder des Lenkers an dem Treibstangenabschnitt angelenkt ist und die andere der Lagerungen an einem zweiten Treibstangenabschnitt oder dem Stulpschienenabschnitt angelenkt ist, wobei in einer Transportstellung der Betätigungshebel, der Lenker und der Treibstangenabschnitt parallel übereinander liegen und der Treibstangenabschnitt in einer entriegelten Stellung liegt.The invention relates to a cuff lever mechanism for the optional locking or unlocking of a folded sash of double-sashed windows, balcony doors or the like with a cuff rail section and at least one drive rod section that is longitudinally displaceable on the cuff rail section, with an actuating lever, with a handlebar, with a mounting of the handlebar in a central area on the operating lever, with a bearing of the second end of the handlebar, with a bearing of one end of the operating lever, at least one of the bearings of the operating lever or the handlebar being articulated on the drive rod section and the other of the bearings being articulated on a second drive rod section or the faceplate section , wherein in a transport position the actuating lever, the handlebars and the drive rod section lie parallel one above the other and the drive rod section lies in an unlocked position.

Ein Treibstangenbeschlag mit einem solchen Stulphebelgetriebe ist aus der EP 1 420 136 A2 bekannt. Bei diesem Stulphebelgetriebe hat die Lagerung des Betätigungshebels in dem Treibstangenabschnitt einen mit dem Betätigungshebel verbundenen Lagerbolzen. Der Lagerbolzen ist vor einer Erstbetätigung von einer als Bohrung in der Treibstange ausgebildeten Mitnahmeverbindung getrennt. Damit kann das Stulphebelgetriebe in der Entriegelungsstellung des Treibstangenbeschlags montiert werden, wobei der Betätigungshebel, der Treibstangenabschnitt und der Lenker platzsparend parallel übereinander liegend transportiert werden können. Nach der Erstbetätigung kennzeichnet die parallel übereinander liegende Stellung des Betätigungshebels, des Lenkers und des Treibstangenabschnitts die Verriegelungsstellung des Stulphebelgetriebes in der der Betätigungshebel in einem Falz zwischen den beiden Flügeln angeordnet ist. Nach der Erstbetätigung ist das Stulphebelgetriebe betriebsbereit. Nachteilig bei dem bekannten Stulphebelgetriebe ist, dass der Lagerbolzen bei der Erstbetätigung über den Treibstangenabschnitt schleift und die Bohrung der Mitnahmeverbindung nur schwer von dem Lagerbolzen gefunden werden kann.A drive rod fitting with such a lever mechanism is from the EP 1 420 136 A2 known. In this cuff lever mechanism, the mounting of the actuating lever in the drive rod section has a bearing pin connected to the actuating lever. Before being actuated for the first time, the bearing pin is separated from a driving connection designed as a bore in the drive rod. In this way, the cuff lever mechanism can be mounted in the unlocked position of the drive rod fitting, with the actuating lever, the drive rod section and the handlebar being able to be transported lying parallel on top of one another in a space-saving manner. After the initial actuation, the position of the actuating lever, the link and the connecting rod section lying parallel on top of one another characterizes the locking position of the cuff lever mechanism in which the actuating lever is arranged in a fold between the two wings. After the initial activation, the lever mechanism is ready for operation. The disadvantage of the known cuff lever mechanism is that the bearing pin rubs over the drive rod section when it is first actuated and the bore of the driver connection can only be found with difficulty by the bearing pin.

Der Erfindung liegt das Problem zugrunde, ein Stulphebelgetriebe der eingangs genannten Art so weiter zu bilden, dass es einen einfachen Transport ermöglicht und einfach in den betriebsbereiten Zustand überführbar ist.The invention is based on the problem of developing a cuff lever mechanism of the type mentioned at the beginning in such a way that it enables simple transport and can easily be converted into the operational state.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass eine der Lagerungen einen Lagerbolzen und ein Federelement hat und dass das Federelement nach einer Erstbetätigung zur Erzeugung eines in Längsrichtung wirkenden Formschlusses zwischen dem Lagerbolzen und einem angrenzenden Abschnitt des Betätigungshebels, des Lenkers, des Stulpschienenabschnitts oder des Treibstangenabschnitts ausgebildet ist.This problem is solved according to the invention in that one of the bearings has a bearing pin and a spring element and that, after an initial actuation, the spring element is designed to produce a form fit acting in the longitudinal direction between the bearing pin and an adjacent section of the operating lever, the handlebar, the cuff rail section or the drive rod section is.

Durch diese Gestaltung ist der eine Lagerbolzen nach der Erstbetätigung in seiner vorgesehenen Position in dem angrenzenden Abschnitt des Betätigungshebels, des Lenkers, des Stulpschienenabschnitts oder des Treibstangenabschnitts gehalten, so dass die Treibstange durch Verschwenkung des Betätigungshebels zwischen einer Verriegelungsstellung des Treibstangenbeschlags und einer Entriegelungsstellung verschoben werden kann. Vor der Erstbetätigung ist die Verbindung des Lagerbolzens mit dem angrenzenden Abschnitt gelöst, so dass der Betätigungshebel zum Transport parallel über die Stulpschiene geschwenkt werden kann, während der zumindest eine Treibstangenabschnitt in der Entriegelungsstellung verbleibt. Nach der Erstbetätigung ist der Betätigungshebel gegenüber der Treibstange in der Entriegelungsstellung ausgeschwenkt und in der Verriegelungsstellung über die Treibstange geschwenkt und damit das Stulphebelgetriebe in den betriebsbereiten Zustand überführt. Damit lässt sich das Stulphebelgetriebe platzsparend in der Entriegelungsstellung transportieren.With this design, the one bearing pin is held in its intended position in the adjacent section of the actuating lever, the handlebar, the cuff rail section or the connecting rod section after the first actuation, so that the connecting rod can be moved between a locking position of the connecting rod fitting and an unlocking position by pivoting the actuating lever . Before the first actuation, the connection of the bearing pin to the adjoining section is released so that the actuating lever can be pivoted parallel over the faceplate for transport, while the at least one drive rod section remains in the unlocked position. After the initial actuation, the actuating lever is swiveled out in relation to the drive rod in the unlocking position and pivoted over the drive rod in the locking position, thus bringing the lever mechanism into the operational state. The forend lever mechanism can thus be transported in the unlocked position to save space.

Die das Federelement aufweisende Lagerung ist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach zugänglich, wenn die Lagerung des Lenkers an dem Stulpschienenabschnitt das Federelement aufweist. In der übereinander liegenden Stellung des Betätigungshebels, des Lenkers und der Stulpschiene ist die das Federelement aufweisende Lagerung von dem Betätigungshebel verdeckt. Diese Stellung kennzeichnet auch im Betrieb eine Verriegelungsstellung, so dass das Federelement nicht stört. Durch ein Verschwenken des Betätigungshebels ist die Position des Federelementes jedoch sichtbar und kann überprüft werden. Die Position der Lagerung wird nach der Erstbetätigung gegenüber dem Stulpschienenabschnitt festgelegt.According to another advantageous development of the invention, the mounting that has the spring element is easily accessible if the mounting of the link on the faceplate section has the spring element. In the superimposed position of the actuating lever, the handlebar and the faceplate, the mounting having the spring element is covered by the actuating lever. This position also indicates a locking position during operation, so that the spring element does not interfere. By pivoting the actuating lever, however, the position of the spring element is visible and can be checked. The position of the storage is determined after the initial activation in relation to the faceplate section.

Die Erzeugung des Formschlusses gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das Federelement mit dem Lagerbolzen verbunden ist und Rasthaken hat und wenn der angrenzende Abschnitt Ausnehmungen zur Aufnahme der Rasthaken hat.According to another advantageous development of the invention, the generation of the form fit is particularly simple in terms of construction if the spring element is connected to the bearing pin and has locking hooks and if the adjoining section has recesses for receiving the locking hooks.

Das Federelement ist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zur Montage und zur Sichtkontrolle einfach zugänglich, wenn der Lagerbolzen der das Federelement aufweisenden Lagerung vor der Erstbetätigung in einem Langloch des angrenzenden Abschnitts längsverschieblich geführt ist.According to another advantageous development of the invention, the spring element is easily accessible for assembly and visual inspection if the bearing pin of the mounting having the spring element is guided in a longitudinally displaceable manner in an elongated hole in the adjoining section before the first actuation.

Die Fertigung und die Montage des Federelements gestalten sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn das Federelement als Federblech ausgebildet ist.According to another advantageous development of the invention, the manufacture and assembly of the spring element are particularly simple if the spring element is designed as a spring steel sheet.

Das Federblech vermag gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine Doppelfunktion als verschleißminderndes Reibblech zu erfüllen, wenn das als Federblech ausgebildete Federelement zwischen dem Lenker und dem Stulpschienenabschnitt angeordnet ist. Durch diese Gestaltung erzeugt das Federblech eine Beabstandung des Lenkers von dem Stulpschienenabschnitt.According to another advantageous development of the invention, the spring plate can fulfill a double function as a wear-reducing friction plate if the spring element, which is designed as a spring plate, is arranged between the link and the faceplate section. As a result of this design, the spring plate creates a spacing between the link and the faceplate section.

Zur weiteren Vereinfachung der Erzeugung des Formschlusses trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn der angrenzende Abschnitt eine Rampe zur Führung der Rasthaken bei der Erstbetätigung in die Ausnehmungen hat.According to another advantageous development of the invention, it helps to further simplify the creation of the form fit if the adjoining section has a ramp for guiding the latching hooks into the recesses during the initial actuation.

Eine alternative Erzeugung des Formschlusses gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das Federelement mit dem angrenzenden Abschnitt verbunden ist und wenn die Rasthaken den Lagerbolzen umgreifen.According to another advantageous development of the invention, an alternative generation of the form fit is particularly simple in terms of construction when the spring element is connected to the adjoining section and when the latching hooks grip around the bearing bolt.

Die Verrastung des Federelementes mit dem Lagerbolzen gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Rasthaken Rampen aufweisen.The latching of the spring element with the bearing pin is particularly simple according to another advantageous development of the invention if the latching hooks have ramps.

Figur 1 zeigt ein Fenster mit einem Rahmen 1 und zwei Flügeln 2, 3 ohne Mittelpfosten. Einer der Flügel 2 hat eine Handhabe 4 zum Antrieb eines Treibstangenbeschlages 5 mit mehreren Verschlüssen 6 und ist damit als Hauptflügel ausgebildet. Der andere Flügel 3 hat einen im Falz zwischen den Flügeln 2, 3 angeordnetes Stulphebelgetriebe 7 zum Antrieb einer Treibstange 8 und ist damit als unterschlagener Flügel 3 ausgebildet. Die Treibstange 8 steuert verschiedene Verschlüsse 9 zur Verriegelung des unterschlagenen Flügels 3 in dem Rahmen 1 an. Figure 1 shows a window with a frame 1 and two sashes 2, 3 without a central mullion. One of the wings 2 has a handle 4 for driving a drive rod fitting 5 with several locks 6 and is thus designed as a main wing. The other wing 3 has a cuff lever mechanism 7 arranged in the rebate between the wings 2, 3 for driving a drive rod 8 and is thus designed as a wing 3 that is folded down. The drive rod 8 controls various locks 9 for locking the folded leaf 3 in the frame 1.

Figur 2 zeigt das Stulphebelgetriebe 7 aus Figur 1 in einer Draufsicht von dem als Hauptflügel ausgebildeten Flügel 2 aus gesehen. Zur Vereinfachung der Zeichnung sind Bauteile des unterschlagenen Flügels 3, an dem das Stulphebelgetriebe 7 befestigt ist, nicht dargestellt. Das Stulphebelgetriebe 7 hat einen schwenkbar gelagerten, parallel über einen Stulpschienenabschnitt 11 angeordneten Betätigungshebel 10. Diese parallel über dem Stulpschienenabschnitt 11 liegende Stellung kennzeichnet nach einer Erstbetätigung eine Verriegelungsstellung, in der der unterschlagene Flügel 3 in dem Rahmen 1 verriegelt ist. Vor der Erstbetätigung befindet sich das Stulphebelgetriebe 7 jedoch in einer Montage- oder Transportstellung, in der der Betätigungshebel 10 platzsparend über dem Stulpschienenabschnitt 11 liegt. Dabei soll sich das Stulphebelgetriebe 7 jedoch in einer Entriegelungsstellung der Verschlüsse 9 befinden. Damit kann das Stulphebelgetriebe 7 in entriegelter Stellung bei geöffneten Flügeln 2, 3 montiert und mit der Erstbetätigung in einen Zustand gebracht werden, in der der unterschlagene Flügel 3 verriegelbar ist. Figure 2 shows the cuff lever mechanism 7 Figure 1 seen in a plan view of the wing 2 designed as a main wing. To simplify the drawing, components of the underlaid wing 3, to which the lever mechanism 7 is attached, are not shown. The cuff lever mechanism 7 has a pivotably mounted actuating lever 10 arranged in parallel over a cuff rail section 11. Before the first actuation, however, the cuff lever mechanism 7 is in an assembly or transport position in which the actuating lever 10 lies above the cuff rail section 11 in a space-saving manner. In this case, however, the cuff lever mechanism 7 should be in an unlocked position of the locks 9. In this way, the forend lever mechanism 7 can be mounted in the unlocked position with the leaves 2, 3 open and, with the initial actuation, can be brought into a state in which the underlaid leaf 3 can be locked.

Figur 3 zeigt das Stulphebelgetriebe 7 aus Figur 2 nach der Erstbetätigung, in der der unterschlagene Flügel 3 entriegelt ist. Hierbei ist zu erkennen, dass der Betätigungshebel 10 von dem Stulpschienenabschnitt 11 weggeschwenkt und über einen Lenker 12 gehalten ist. Figure 3 shows the cuff lever mechanism 7 Figure 2 after the first actuation, in which the underlaid sash 3 is unlocked. It can be seen here that the actuating lever 10 is pivoted away from the faceplate section 11 and is held via a link 12.

Figur 4 zeigt das Stulphebelgetriebe 7 aus Figur 3 in einer Ansicht von unten. An dem Stulpschienenabschnitt 10 ist ein Treibstangenabschnitt 13 der Treibstange 8 aus Figur 1 verschieblich geführt. Das Stulphebelgetriebe 7 hat eine Lagerung 14 eines Endes des Betätigungshebels 10 an dem Treibstangenabschnitt 13, eine Lagerung 15 eines ersten Endes des Lenkers 12 im mittleren Bereich des Betätigungshebels 10 und eine Lagerung 16 des zweiten Endes des Lenkers 12 an dem Stulpschienenabschnitt 11. Die Lagerung 14 des Betätigungshebels 10 an dem Treibstangenabschnitt 13 ist durch ein Langloch 17 des Stulpschienenabschnitts 11 geführt. Die Lagerung 16 des zweiten Endes des Lenkers 12 an dem Stulpschienenabschnitt 11 ist von einem Federelement 18 in der eingezeichneten Lage gehalten. Hierzu ist das Federelement 18 an einem angrenzenden Abschnitt 19 des Stulpschienenabschnitts 11 verrastet. Figure 4 shows the cuff lever mechanism 7 Figure 3 in a view from below. On the faceplate section 10, a drive rod section 13 of the drive rod 8 is made Figure 1 slidably guided. The cuff lever mechanism 7 has a bearing 14 of one end of the operating lever 10 on the drive rod section 13, a bearing 15 of a first end of the handlebar 12 in the middle area of the operating lever 10 and a bearing 16 of the second end of the handlebar 12 on the cuff rail section 11. The bearing 14 of the actuating lever 10 on the drive rod section 13 is guided through an elongated hole 17 in the faceplate section 11. The mounting 16 of the second end of the link 12 on the faceplate section 11 is held in the position shown by a spring element 18. For this purpose, the spring element 18 is latched onto an adjoining section 19 of the faceplate section 11.

In einer alternativen, nicht dargestellten Ausführungsform kann das Stulphebelgetriebe 7 über den Lenker 12 und den Betätigungshebel 10 auch zwei unabhängige Treibstangenabschnitte gegenläufig antreiben. In einer anderen, ebenfalls nicht dargestellten Ausführungsform kann der eine Treibstangenabschnitt 13, statt über den Betätigungshebel 10, über den Lenker 12 angetrieben werden.In an alternative, not shown embodiment, the cuff lever mechanism 7 can also drive two independent drive rod sections in opposite directions via the handlebar 12 and the actuating lever 10. In another embodiment, also not shown, the one driving rod section 13 can be driven via the handlebar 12 instead of the actuating lever 10.

Figur 5 zeigt stark vergrößert die Lagerung 16 des Lenkers 12 an dem Abschnitt 19 des Stulpschienenabschnitts 11 vor der Erstbetätigung des Stulphebelgetriebes 7. Zur Vereinfachung sind der Lenker 12 nicht dargestellt und von der Lagerung 16 ein Lagerbolzen 20 dargestellt. Der Lagerbolzen 20 ist in einem Langloch 21 des Abschnitts 19 des Stulpschienenabschnitts 11 längsverschieblich geführt. Zwei von dem Federelement 18 abgewinkelte Rasthaken 22 dringen in das Langloch 21 des Abschnitts 19 des Stulpschienenabschnitts 11 ein. Das Federelement 18 ist als Federblech ausgebildet und liegt flächig auf dem Abschnitt 19 auf. Damit liegt im montierten Zustand das Federelement 18 zwischen dem Abschnitt 19 des Stulpschienenabschnitts 11 und dem Lenker 12. Figure 5 shows, greatly enlarged, the mounting 16 of the handlebar 12 on the section 19 of the cuff rail section 11 before the cuff lever mechanism 7 is actuated for the first time To simplify matters, the link 12 is not shown and a bearing pin 20 of the bearing 16 is shown. The bearing pin 20 is guided in a longitudinally displaceable manner in an elongated hole 21 of the section 19 of the faceplate section 11. Two latching hooks 22 angled from the spring element 18 penetrate into the elongated hole 21 of the section 19 of the faceplate section 11. The spring element 18 is designed as a spring plate and lies flat on the section 19. Thus, in the assembled state, the spring element 18 lies between the section 19 of the faceplate section 11 and the link 12.

Bei der Erstbetätigung wird der Lagerbolzen 20 der Lagerung 16 im Langloch 21 verschoben, bis er in die in Figur 6 dargestellte Stellung gelangt. In dieser Stellung schnappen die Rasthaken 22 in Ausnehmungen 23 des Langlochs 21 ein. In dieser Stellung ist der Lagerbolzen 20 formschlüssig mit dem Abschnitt 19 des Stulpschienenabschnitts 19 verbunden und damit dauerhaft in seiner Lage gehalten. Das Langloch 21 hat Rampen 24 zur Führung der Rasthaken 22 in die Ausnehmungen 23.When first actuated, the bearing pin 20 of the bearing 16 is moved in the elongated hole 21 until it is in the in Figure 6 position shown. In this position, the latching hooks 22 snap into recesses 23 of the elongated hole 21. In this position, the bearing pin 20 is positively connected to the section 19 of the faceplate section 19 and is thus permanently held in its position. The elongated hole 21 has ramps 24 for guiding the latching hooks 22 into the recesses 23.

Figur 7 zeigt eine weitere Ausführungsform einer Lagerung 116 des Lenkers 12 an einem Abschnitt 119 des in den Figuren 2 bis 4 dargestellten Stulpschienenabschnitts 11 mit einem Federelement 118 vor der Erstbetätigung. Auch bei dieser Ausführungsform hat der Abschnitt 119 ein Langloch 121. Rasthaken 122 des Federelementes 118 liegen jedoch an der Außenseite des Abschnitts 119 an und stehen in der dargestellten Transportstellung Rampen 124 gegenüber. Figure 7 FIG. 11 shows a further embodiment of a mounting 116 of the handlebar 12 on a section 119 of the FIG Figures 2 to 4 faceplate section 11 shown with a spring element 118 before the initial actuation. In this embodiment, too, the section 119 has an elongated hole 121. However, latching hooks 122 of the spring element 118 rest on the outside of the section 119 and face ramps 124 in the illustrated transport position.

Figur 8 zeigt die Ausführungsform der Lagerung 116 aus Figur 7 nach der Erstbetätigung. Die Rasthaken 122 des Federelementes 118 sind in Ausnehmungen 123 des Abschnitts 119 eingeschnappt und erzeugen damit einen Formschluss des Lagerbolzens 120 in Längsrichtung des Abschnitts 119. Figure 8 shows the embodiment of the bearing 116 from Figure 7 after the first activation. The latching hooks 122 of the spring element 118 are snapped into recesses 123 of the section 119 and thus generate a form fit of the bearing pin 120 in the longitudinal direction of the section 119.

Figur 9 zeigt eine weitere Ausführungsform einer Lagerung 216 des Lenkers 12 an einem Abschnitt 219 des Stulpschienenabschnitts 11 aus den Figuren 2 bis 4 vor der Erstbetätigung. Ein Lagerbolzen 220 der Lagerung 216 ist mit einem Federelement 218 verbunden. Das Federelement 218 ist in einem Langloch 221 des Abschnitts 219 verschieblich geführt und hat in das Langloch 221 eindringende, als Abwinklungen ausgebildete Rasthaken 222. Figure 9 FIG. 10 shows a further embodiment of a mounting 216 of the handlebar 12 on a section 219 of the cuff rail section 11 from FIG Figures 2 to 4 before the first activation. A bearing pin 220 of the bearing 216 is connected to a spring element 218. The spring element 218 is guided displaceably in an elongated hole 221 of the section 219 and has latching hooks 222 which penetrate into the elongated hole 221 and are designed as bends.

Verschiebt man den Lagerbolzen 220 aus Figur 9 durch eine Erstbetätigung in die in Figur 10 dargestellte Stellung, schnappen die als Abwinklungen ausgebildeten Rasthaken 222 des Federelements 218 hinter in das Langloch 221 hineinragende Stege 225 und haltern den Lagerbolzen 220 formschlüssig. Die Stege 225 begrenzen damit Ausnehmungen 223 zur Aufnahme der Rasthaken 222. Die Stege 225 und die als Abwinklungen ausgebildeten Rasthaken 222 weisen Rampen 224 auf.One moves the bearing pin 220 out Figure 9 through an initial activation in the in Figure 10 position shown, the latching hooks 222 of the spring element 218, which are designed as bends, snap behind webs 225 protruding into the elongated hole 221 and hold the bearing pin 220 in a form-fitting manner. The webs 225 thus delimit recesses 223 for receiving the latching hooks 222. The webs 225 and the latching hooks 222 designed as bends have ramps 224.

Figur 11 zeigt eine weitere Ausführungsform einer Lagerung 316 des Lenkers 12 an einem Abschnitt 319 des Stulpschienenabschnitts 11 vor der Erstbetätigung. Diese Ausführungsform unterscheidet sich von den zuvor beschriebenen dadurch, dass ein Federelement 318 an dem Abschnitt 319 befestigt ist und zwei, einem Lagerbolzen 320 der Lagerung 316 gegenüberstehende Rasthaken 322 hat. Die Rasthaken 322 weisen Rampen 324 auf und der Lagerbolzen 320 ist in einem Langloch 321 des Abschnitts 319 geführt. Figure 11 shows a further embodiment of a mounting 316 of the handlebar 12 on a section 319 of the cuff rail section 11 before the first actuation. This embodiment differs from the previously described ones in that a spring element 318 is fastened to the section 319 and has two latching hooks 322 opposite a bearing bolt 320 of the bearing 316. The latching hooks 322 have ramps 324 and the bearing pin 320 is guided in an elongated hole 321 of the section 319.

Verschiebt man durch eine Erstbetätigung den Lagerbolzen 320 in dem Langloch 321 in die in Figur 12 dargestellte Stellung, schnappen die Rasthaken 322 hinter dem Lagerbolzen 320 ein und sichern diesen formschlüssig in der dargestellten Lage.If you move the bearing pin 320 in the elongated hole 321 into the in Figure 12 position shown, the locking hooks 322 snap behind the bearing pin 320 and secure this positively in the position shown.

In den dargestellten Ausführungsformen ist beispielhaft die Lagerung 16 des Lenkers 12 an dem Stulpschienenabschnitt 11 verrastbar gestaltet. Alternativ dazu können auch die Lagerung 14 des Betätigungshebels 10 an dem Treibstangenabschnitt 13 oder die Lagerung 15 des Lenkers 12 an dem Betätigungshebel 10 analog zu den in den Figuren 5 bis 12 beschriebenen Ausführungsformen verrastbar gestaltet sein.In the illustrated embodiments, the mounting 16 of the link 12 is designed to be latched on the faceplate section 11, for example. Alternatively, the mounting 14 of the actuating lever 10 on the drive rod section 13 or the mounting 15 of the handlebar 12 on the actuating lever 10 can be analogous to the ones shown in FIGS Figures 5 to 12 described embodiments be designed to be latched.
