Der Schalthebel wird dabei gegen die Wirkung von Federn in die jeweilige Schaltstellung gebracht und kehrt selbsttätig in die Ausgangsstellung zurück.Switching device for several control elements to operate hydraulically or pneumatically operated movement devices The invention relates to a switching device for several hydraulic or pneumatic controls Movement devices, which has a shift lever that is movable in all directions Either one control unit alone or several control units can be switched together are. The shift lever is against the action of springs in the respective switch position and returns automatically to the starting position.

Bei einer bekannten Schaltvorrichtung für eine mit Druckluft betriebene Arbeitsmaschine ist der Schalthebel in einer Gelenkkugel gelagert. über einen am Schalthebel befestigten Teller können bis zu zwei Steuerventile gleichzeitig geöffnet oder geschlossen werden.In a known switching device for a compressed air operated On the working machine, the gearshift lever is mounted in a joint ball. about an am Shift lever attached plates can open up to two control valves at the same time or be closed.

Es ist die Aufgabe der Erfindung, für derartige Steuerorgane eine Schaltvorrichtung zu schaffen, die sich aus Teilen zusammensetzt, die sich ohne besondere Genauigkeit herstellen lassen.It is the object of the invention to provide one for such control members To create switching device, which is composed of parts that are without have special accuracy produced.

Dies geschieht durch die erfindungsgemäße Vereinigung folgender Merkmale: Der Hebel ist in an sich bekannter Weise in einer Scheibe aus nachgiebigem, elastischem Kunststoff gelagert, die er durchsetzt. Zu beiden Seiten der elastischen Scheibe sind Kegelstumpffedern angeordnet, die mit ihrem Ende von kleinerem Durchmesser an der elastischen Scheibe anliegen. Der Hebel greift mit seinem den Steuerorganen zugekehrten Abschnitt in mehrere, unter einem Winkel zueinander angeordnete, schwenkbar gelagerte Gabeln ein, die ihrerseits auf die Steuerorgane einwirken.This is done by combining the following features according to the invention: The lever is in a manner known per se in a disk made of flexible, elastic Plastic stored, which he penetrates. On both sides of the elastic washer are arranged frustoconical springs, which with their end of smaller diameter rest against the elastic washer. The lever engages with his the control organs facing section in several, arranged at an angle to each other, pivotable stored forks, which in turn act on the control organs.

Diese Lagerung des Hebels in einer federnd gehaltenen elastischen Scheibe sowie dessen Zusammenwirken mit Gabeln verbürgt eine besonders einfache Herstellung, bei der es auf keine besondere Genauigkeit ankommt. Die Herstellungskosten lassen sich dadurch wesentlich senken. Trotz des einfachen Aufbaus erlaubt die Vorrichtung genaue Schaltstellungen der verschiedenen Steuerorgane. Ein weiterer Vorteil ist die reibungsarme Lagerung des Schalthebels, die ein besonders leichtgängiges Schalten ermöglicht.This storage of the lever in a resiliently held elastic Disc and its interaction with forks guarantees a particularly simple one Manufacture that does not require any particular accuracy. The manufacturing cost can be reduced significantly as a result. Despite the simple structure, the device allows exact switching positions of the various control organs. Another benefit is the low-friction mounting of the shift lever, which enables particularly easy shifting enables.

Die Erfindung wird an Hand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Es zeigt F i g. 1 die Ansicht einer Schaltvorrichtung, F i g. 2 die Draufsicht auf die Schaltvorrichtung, wobei eine Wand des Gehäuses derselben entfernt ist und zwei Schalter teilweise geschnitten sind und F i g. 3 eine Seitenansicht der Schaltvorrichtung, wobei die eine Seitenwand des Gehäuses entfernt ist. In den F i g. 1 bis 3 ist mit 10 das Gehäuse einer Schaltvorrichtung 11 für die Steuerorgane 12 bis 15 hydraulischer Bewegungsvorrichtungen in einem Personenkraftwagen bezeichnet. Als Steuerorgane können beispielsweise jeweils ein in einem Gehäuse angeordnetes Ein- und Auslaßventil verwendet werden. An einer Seitenschiene 16 eines nicht näher dargestellten Sitzes ist die Schaltvorrichtung 11 befestigt. Sie kann aber auch am Armaturenbrett angeordnet sein. Das Steuerorgan 12 dient beispielsweise zum Schwenken des Sitzes um eine horizontale, quer zur Fahrzeuglängsrichtung verlaufenden Achse, das Steuerorgan 13 zum Heben und Senken des Sitzes, das Steuerorgan 14 zum Verschieben des Sitzes in Fahrzeuglängsrichtung und das Steuerorgan 15 zum Schwenken der Rückenlehne um eine horizontale Achse.The invention is explained in more detail using an exemplary embodiment shown in the drawings. It shows F i g. 1 is a view of a switching device, FIG. Fig. 2 is a plan view of the switching device with a wall of the housing thereof removed and two switches partially cut away, and Fig. 2. 3 is a side view of the switching device with one side wall of the housing removed. In the F i g. 1 to 3, 10 denotes the housing of a switching device 11 for the control members 12 to 15 of hydraulic movement devices in a passenger car. An inlet and outlet valve arranged in a housing, for example, can be used as control elements. The switching device 11 is attached to a side rail 16 of a seat not shown in detail. But it can also be arranged on the dashboard. The control member 12 is used, for example, to pivot the seat about a horizontal axis running transversely to the longitudinal direction of the vehicle, the control member 13 to raise and lower the seat, the control member 14 to move the seat in the longitudinal direction of the vehicle and the control member 15 to pivot the backrest about a horizontal axis .

An den Steuerorganen 13 und 14 sind rechtwinklig zueinander angeordnete Schaltgabeln 13'. und 14' schwenkbar gelagert. In die Schaltgabeln 13' und 14' greift das verschiebbare Ende des Schaftes 19' eines Schalthebels 19. Der Schaft 19' weist im Bereich einer mit der Gehäusewand 10' fest verbundenen Hülse 20, in der der Schalthebel 19 allseitig beweglich gelagert ist, eine Ringnut auf. In der Ringnut ist eine Scheibe 21 befestigt, die aus einem nachgiebigen, elastischen Kunststoff besteht. Auf den beiden Seiten der Scheibe liegen Kegelstumpffedern 22 mit den Enden mit kleinerem Durchmesser an, während die Enden mit größerem Durchmesser sich auf einem Sprengring 23 bzw. auf einem abgewinkelten Flansch der Hülse 20 abstützen. Der Außenrand der Scheibe 21 hat von dem Innenrand der Hülse 20 einen kleinen Abstand, so daß sich die Scheibe 21 mit Spiel bewegen läßt. Mit dem Schaft 19' des Schalthebels 19 lassen sich die Schaltgabeln 13' bzw.14' in Richtung des Doppelpfeiles 24 bzw. 25 schwenken. Es ist auch möglich, den Schalthebel 19 in die beiden diagonalen Richtungen, wie sie die Doppelpfeile 27 und 28 anzeigen, zu drücken. Der Fahrzeugsitz läßt sich dadurch gleichzeitig in zwei Bewegungsrichtungen verstellen. Bei losgelassenem. Schalthebel .19 kehrt. dieser in seine in der Zeichnung gezeigte Ausgangsstellung zurück, in der der Fährzeügsiti in seinen augenblicklichen Stellung stehenbleibt.Shift forks 13 'arranged at right angles to one another are attached to control members 13 and 14. and 14 'pivotally mounted. The displaceable end of the shaft 19 'of a shift lever 19 engages in the shift forks 13' and 14 '. The shaft 19' has an annular groove in the area of a sleeve 20 firmly connected to the housing wall 10 ', in which the shift lever 19 is movably mounted on all sides on. In the annular groove, a disk 21 is attached, which consists of a flexible, elastic plastic. On both sides of the disc there are frustoconical springs 22 with the ends with a smaller diameter, while the ends with a larger diameter are supported on a snap ring 23 or on an angled flange of the sleeve 20. The outer edge of the disc 21 has a small distance from the inner edge of the sleeve 20, so that the disc 21 can be moved with play. With the shaft 19 'of the shift lever 19, the shift forks 13' and 14 'can be pivoted in the direction of the double arrow 24 and 25, respectively. It is also possible to press the shift lever 19 in the two diagonal directions as indicated by the double arrows 27 and 28. The vehicle seat can thereby be adjusted in two directions of movement at the same time. When released. Shift lever .19 turns. this back to its starting position shown in the drawing, in which the Fährzeügsiti stops in its current position.

Schaltgabeln nach der Art der Gabeln 13' und 14' lassen sich auch für ein einzelnes Steuerorgan verwenden. -So werden--beispielsweise-die. Steuerorgane 12 bzw. 15 durch Gabeln 12' bzw. 15' geschaltet, in die an Drehschaltern 17 bzw. 18 befestigte Schaltbölzen 17'-bzvv. 18' greifen.. Für -die- Drehschälter 17 und 18" die . Gabeln- -1.7"und 1$' sowie die Steuerorgane 12 und--15 wird jedoch.für .sich allein kein Schutz begehrt. Die Doppelpfeile 29 bzw. 30 geben dieyDrehrichtung .der Drehschalter 17 bzw.-18 an. _ ,-Shift forks like the forks 13 'and 14' can also be used for a single control member. -So be - for example - the. Control members 12 and 15, respectively, switched by forks 12 'and 15', into which switching pins 17'-and / or. 18 'take hold. For -the- rotary switches 17 and 18 "the. Forks -1.7" and 1 $' as well as the control elements 12 and -15, however, no protection is sought for. The double arrows 29 and 30 indicate the direction of rotation of the rotary switches 17 and -18. _, -
