Abstract

The invention relates to a stop device (1). The control element (2) of said stop device, which is provided with notches (5), can be displaced past a fixed stop member (6) comprising a stop element (8) which supports itself in an elastic manner on a cam plate (3) of the regulating element (2). Said stop element (8) is held on an elastically positioned base part (7) of the stop member (6) in the direction of regulation, in such a way that it can be deviated. When a summit (4) of the cam plate (3) is passed, the restoring force of the stop element (8) causes a secure engagement in the following notch (4).

Der Erfindung liegt die Aufgabe zugrunde, die Rastwirkung zu verbessern .The invention has for its object to improve the locking effect.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.
Beim linearen oder rotatorischen Verschieben des Stellglieds relativ zum Rastglied rollt der Wälzkörper aus seiner Zentrierlage reibungsarm und leichtgängig in eine Auslenklage. Das federbelastete Basisteil ist seitlich fixiert. Durch Gestaltung der Ablaufkurven am Basisteil kann die Haptik zusätzlich beeinflußt werden. Im oberen Totpunkt der jeweiligen Rastkuppe ist die Rückstellkraft größer die Reibungskraft, wodurch das gegen die Stellrichtung ausgelenkte Rastelement in seine Ausgangslage sich zurückrollt und dabei in die nächste Rastkerbe der Rastkurve eingreift. Dadurch ist es möglich, die Rastspitzen der Rastkurve stärker abzurunden und damit die Bedienhaptik zu verbessern und die Abnutzung zu verringern. Der Wälzkδrper ist in der Mittellage in der trichterförmigen Zentrierkerbe formschlüssig gehalten, was eine genau definierte Rastlage des Stellglieds ergibt.When the actuator is moved linearly or rotationally relative to the locking element, the rolling element rolls out of its centering position with little friction and smoothly into a deflection position. The spring-loaded base part is fixed on the side. The haptics can also be influenced by designing the flow curves on the base part. At the top dead center of the respective locking dome, the restoring force is greater than the frictional force, as a result of which the locking element deflected against the direction of adjustment rolls back into its starting position and thereby engages in the next locking notch of the locking curve. This makes it possible to round off the locking peaks of the locking curve more strongly and thus to improve the operating feel and reduce wear. The roller body is held in the middle position in the funnel-shaped centering notch, which results in a precisely defined locking position of the actuator.
Ein weiterer Vorteil besteht darin, daß das Rastelement nicht nur seitlich in der Stellrichtung sondern auch in einer gestaltbaren Kurve senkrecht dazu ausgelenkt wird. Daraus ergibt sich in der Rastrichtung ein zusätzlicher Federweg mit zusätzlicher Rückstellreserve, die die Rastsicherheit weiter erhöht .Another advantage is that the locking element is deflected not only laterally in the direction of adjustment but also in a curve that can be designed perpendicular to it. This results in an additional spring travel in the locking direction with an additional resetting reserve, which further increases the locking security.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den in den Ansprüchen 2 bis 7 gekennzeichneten Merkmalen.Advantageous further developments of the invention result from the features characterized in claims 2 to 7.
Durch die Weiterbildung nach den Anspruch 2 und 3 kann die Rasteinrichtung in gleicher Weise in entgegengesetzten Richtungen betätigt werden.Through the development according to claims 2 and 3, the locking device can be operated in the same way in opposite directions.
Durch die Weiterbildung nach Anspruch 4 kann die maximale Bedienkraft für eine weniger harte Haptik verringert werden, wobei das Zurückrollen des Wälzkörpers einen deutlich wahrnehmbaren Schnappeffekt ergibt . Durch die Anschlagflanken nach Anspruch 5 kann die seitliche Auslenkbewegung des Rastelements begrenzt und die initiale Rückstellkraft erhöht werden.Through the development according to claim 4, the maximum operating force for a less hard haptic can be reduced, the rolling back of the rolling element producing a clearly perceptible snap effect. The stop flanks according to claim 5 limit the lateral deflection movement of the latching element and increase the initial restoring force.
Die Weiterbildung nach Anspruch 6 ergibt eine erhöhte Rückstellkraft über einen längeren Rollweg.The development according to claim 6 results in an increased restoring force over a longer taxiway.
Die Rastkugel nach Anspruch 7 hochwertige billig erwerbbare Lagerkugel ausgebildet sein.

Nach Figur 1 weist eine Rasteinrichtung 1, ein schwenkbar gelagertes Stellglied 2 mit einer peripheren Rastkurve 3 mit teilkreisförmig verteilten Rastkuppen 4 und Rastkerben 5 auf. Ein stationäres radial zum Stellglied angeordnetes Rastglied 6 besteht aus einem radial federnden Basisteil 7 und einem als Rastelement 8 dienenden Wälzkörper in Form einer Lagerkugel, die in einer trichterförmigen, als Zentrierkerbe 9 ausgebildeten Vertiefung des Basisteils 7 rollbar gelagert ist . Die Zentrierkerbe 9 weist zumindest eine zur Rastkurve 3 hin ansteigende Auflaufschräge 10 für das Rastelement 8 auf, der beim Verschieben des Stellglieds in den Bereich der Auflaufschräge 10 rollbar ist. Die Auflaufschrägen 10 des Basisteils 7 sind durch seitliche Anschlagflanken 12 begrenzt. Die Steigung der Auflaufschrägen 10 nimmt zur Anschlagflanke hin zu.According to FIG. 1, a latching device 1 has a pivotably mounted actuator 2 with a peripheral latching curve 3 with latching domes 4 and notches 5 distributed in the form of a part circle. A stationary locking element 6 arranged radially to the actuator consists of a radially resilient base part 7 and a rolling element serving as locking element 8 in the form of a bearing ball, which is mounted in a funnel-shaped depression of the base part 7 and is designed as a centering notch 9. The centering notch 9 has at least one run-up slope 10 for the latching element 8 which rises towards the locking curve 3 and which can be rolled when the actuator is moved into the area of the run-up slope 10. The run-up slopes 10 of the base part 7 are delimited by lateral stop flanks 12. The slope of the run-up slopes 10 increases towards the stop flank.
Die Rastkerben 5 des Stellglieds 2 sind jeweils durch entgegengesetzt geneigten Ablaufschrägen 11 der Rastkurve 3 ausgeformt, wobei diese aus unmittelbar den mehrfach aufeinander folgenden Ablaufschrägen 11 von wechselnder Steigung gebildet ist. Die Steigung der Ablaufschräge nimmt zur Rastkuppe 4 hin ab. Das Stellglied 2 ist mittels eines Bedienhebels 13 in beiden Schwenkrichtungen betätigbar.The locking notches 5 of the actuator 2 are each formed by oppositely inclined run-off slopes 11 of the locking curve 3, these directly from the multiple successive tapered slopes 11 is formed by changing incline. The slope of the run-off slope decreases towards the detent 4. The actuator 2 can be actuated in both pivot directions by means of an operating lever 13.
Nach Figur 2 ist das Stellglied um ca. ein viertel einer Verstellteilung weitergeschwenkt, wobei das Rastelement 8 entlang der Ablaufschräge 11 und der Auflaufschräge 10 in eine freie Zwischenstellung gerollt ist. Dabei ist das Basisteil um einen sich aus den beiden Steigungen und der seitlichen Auslenkung ergebenden Hub senkrecht zur Verstellrichtung ausgelenkt worden.According to Figure 2, the actuator is pivoted about a quarter of an adjustment, the locking element 8 is rolled along the slope 11 and the ramp 10 into a free intermediate position. The base part has been deflected perpendicularly to the adjustment direction by a stroke resulting from the two gradients and the lateral deflection.
Nach Figur 3 ist das Stellglied 2 in eine Schwellenstellung weiter geschwenkt worden, in der sich das Rastelement 8 gerade auf der Spitze der Rastkuppe 4 befindet und an der Anschlagflanke 12 des Basisteils 7 anliegt. Die aus den Einspannkräften resultierende Rückstellkraft ist bereits etwas größer als die Reibungskraft, sodaß das Rastelement 8 entlang der Auflaufschräge 10 in seine in der Figur 4 dargestellte mittlere Zentrierstellung zurück schnappen kann, wie es aus dem angedeuteten Kräfteparallelogramm erkennbar ist . Dabei gelangt das Rastelement 8 über die Rastkuppe in den absteigenden Kurvenbereich der nächsten Ablaufschräge 11, ohne daß dabei das Stellglied 2 aktiv weiter geschwenkt werden mußte. Das Rastelement 8 drückt nun auf diese Ablaufschräge 11 derart, daß das Stellglied gemäß dem gekrümmten Pfeil selbsttätig und sicher in die nächste Raststellung weiterbewegt wird. According to Figure 3, the actuator 2 has been pivoted further into a threshold position in which the locking element 8 is just on the tip of the locking dome 4 and abuts the stop flank 12 of the base part 7. The restoring force resulting from the clamping forces is already somewhat greater than the frictional force, so that the locking element 8 can snap back along the ramp 10 into its central centering position shown in FIG. 4, as can be seen from the indicated parallelogram of forces. In this case, the locking element 8 reaches the descending curve area of the next run-off slope 11 via the locking dome, without the actuator 2 having to be actively pivoted further. The latching element 8 now presses on this run-off slope 11 in such a way that the actuator is automatically and safely moved into the next latching position in accordance with the curved arrow.
