Description

Die Erfindung betrifft einen Mehrweg-Schalthebel gemäß dem Oberbegriff des Anspruches 1.The invention relates to a reusable shift lever according to the preamble of claim 1.

Mehrweg-Schalthebel dieser Gattung werden zur manuellen Steuerung von Bewegungsvorgängen in mehreren Richtungen verwendet. Durch Verschwenken des Schalthebels in verschiedene Richtungen werden verschiedene Steuerelemente betätigt, die einen Bewegungsvorgang in der jeweiligen zugeordneten Richtung auslösen. Die Steuerelemente können elektrische Schalter, elektronische Näherungsschalter, pneumatische oder hydraulische Schaltventile oder sonstige Steuerelemente sein, die durch die Schaltachse ein- und ausgeschaltet werden oder ein der Auslenkung der Schaltachse proportionales Steuersignal liefern. Solche Schalthebel können z.B. zur Steuerung der Bewegung von Maschinenteilen, wie Greifern, Armen und dgl. verwendet werden. Insbesondere werden solche Schalthebel auch zur Steuerung bei Spiel- und Unterhaltungsautomaten eingesetzt.Reusable shift levers of this type are used for manual control of movements in several directions. By pivoting the shift lever in different directions, various control elements are actuated, which trigger a movement process in the respective assigned direction. The control elements can be electrical switches, electronic proximity switches, pneumatic or hydraulic switching valves or other control elements which are switched on and off by the switching axis or which deliver a control signal proportional to the deflection of the switching axis. Such shift levers can e.g. to control the movement of machine parts such as grippers, arms and the like. In particular, such shift levers are also used to control gaming and entertainment machines.

Wird der manuell zu betätigende Mehrweg-Schalthebel freigegeben, so muß er in seine Grundstellung zurückgestellt werden. Bei bekannten Mehrweg-Schalthebeln werden elastische Kräfte zum Rückstellen der Schaltachse verwendet. Sind nur wenige Schaltrichtungen vorgesehen, so kann die Rückstellkraft durch jeweils indiesen Schaltrichtungen wirkende Federn erzeugt werden. Bei einer größeren Zahl von Schaltrichtungen wird die Rückstellkraft durch eine Lagerung der Schaltachse in einem gummielastischen Material bewirkt. Die Rückstel- lung des Schalthebels durch elastische Kräfte" hat den Nachteil, daß die die elastische Rückstellkraft erzeugenden Elemente einem Verschleiß und einer Materialermüdung unterworfen sind. Die Rückstellkraft läßt daher bei längerem Gebrauch des Schalthebels nach und Federelemente können brechen.If the manually operated reusable shift lever is released, it must be returned to its basic position. In known reusable shift levers, elastic forces are used to reset the shift axis. If only a few switching directions are provided, the restoring force can be generated by springs acting in each of these switching directions. With a larger number of switching directions, the restoring force is brought about by mounting the switching axis in a rubber-elastic material. The Rückstel- lun g of the shift lever by elastic forces "has the disadvantage that the elastic restoring force generating elements to wear and fatigue are subject. Therefore, the restoring force can be prolonged use of the shift lever by and spring elements may break.

Der Erfindung liegt die Aufgabe zugrunde, einen Mehrweg-Schalthebel zu schaffen, der bei einfachem Aufbau und hoher Betriebssicherheit praktisch keinem Verschleiß und keiner Materialermüdung unterworfen ist.The invention has for its object to provide a reusable shift lever which is practically no wear and fatigue subject to simple structure and high operational safety.

Diese Aufgabe wird bei einem Mehrweg-Schalthebel der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teils des Anspruches 1.This object is achieved according to the invention in a reusable shift lever of the type mentioned at the outset by the features of the characterizing part of claim 1.

Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and developments of the invention are specified in the subclaims.

Bei dem erfindungsgemäßen Mehrweg-Schalthebel wird die Rückstellkraft für die Schaltachse durch-einen Permanentmagneten erzeugt. Diese magnetische Rückstellkraft ist keiner Materialermüdung unterworfen. Da die Schaltachse mit der Taumelscheibe frei in dem Hohlzylinder sitzt und nur durch die Magnetkraft gehalten wird, sind keine mechanischen Verbindungsteile und Lagerungen vorhanden, die einem Verschleiß ausgesetzt sind. Der Schalthebel hat daher auch bei starker Beanspruchung eine hohe Lebensdauer.In the reusable shift lever according to the invention, the restoring force for the shift axis is generated by a permanent magnet. This magnetic restoring force is not subject to material fatigue. Since the switching axis with the swash plate sits freely in the hollow cylinder and is held only by the magnetic force, there are no mechanical connecting parts and bearings that are subject to wear. The shift lever therefore has a long service life even under heavy use.

Der Schalthebel ist außerordentlich robust und wegen seiner rein permanentmagnetischen Rückstellung und der fehlenden mechanischen Lagerung der Schaltachse betriebssicher und gegen Störungen nicht anfällig.The shift lever is extremely robust and, due to its purely permanent magnetic reset and the lack of mechanical bearings in the shift axis, it is reliable and not susceptible to faults.

Durch die rotationssymmetrische Anordnung des Magnetrings und der Taumelscheibe ist der Schalthebel in bezug auf die Richtungen und die Anzahl der Schaltwege nicht beschränkt. Richtungen und Anzahl der Schaltwege können frei durch die Gestaltung der Kulissenscheibe bestimmt werden. Derselbe Schalthebel kann für die verschiedensten Anwendungszwecke eingesetzt werden, wobei nur die Kulissenscheibe dem jeweiligen Anwendungszweck .entsprechend gewählt werden muß. Dies wirkt sich vorteilhaft auf die Herstellungskosten und die Lagerhaltung aus. Außerdem kann dadurch der Schalthebel in einfacher Weise für einen anderen Anwendungszweck umgerüstet werden.Due to the rotationally symmetrical arrangement of the magnetic ring and the swash plate, the shift lever is not restricted with regard to the directions and the number of shift paths. The directions and number of switching paths can be freely determined by the design of the link plate. The same shift lever can be used for a wide variety of applications, with only the link plate for the respective application must be chosen accordingly. This has an advantageous effect on manufacturing costs and warehousing. In addition, the shift lever can be easily converted for another application.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen :

  • Figur 1 einen Schalthebel im Axialschnitt und
  • Figur 2 eine Draufsicht auf eine Ausführungsform der Kulissenscheibe.
The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing. Show it :
  • Figure 1 shows a shift lever in axial section and
  • Figure 2 is a plan view of an embodiment of the link plate.

Der Mehrweg-Schalthebel weist ein hohlzylindrisches Gehäuse 10 auf, das axial aneinander anschließend einen Abschnitt größeren und einen Abschnitt kleineren Innendurchmessers hat. Das Gehäuse 10 kann aus einem unmagnetischen Metall, vorzugsweise Leichtmetall oder aus Kunststoff, bestehen. In den Abschnitt mit dem kleineren Durchmesser ist ein zylindrischer Permanent-Magnetring 12 im Paßsitz eingesetzt.The reusable shift lever has a hollow cylindrical housing 10 which axially adjoins a portion of a larger and a portion of a smaller inner diameter. The housing 10 can consist of a non-magnetic metal, preferably light metal or plastic. In the section with the smaller diameter, a cylindrical permanent magnetic ring 12 is inserted in a snug fit.

In den sich axial anschließenden Abschnitt des Gehäuses 10 mit größerem Durchmesser ist ein Hohlzylinder 14 aus einem reibungsarmen Kunststoff ebenfalls im Paßsitz eingesetzt. Die Innendurchmesser der beiden Abschnitte des Gehäuses 10 und der Innendurchmesser des Hohlzylinders 14 sind so gewählt, daß der Hohlzylinder 14 den Magnetring 12 nur an dessen Außenumfang radial überlappt. An dem dem Magnetring 12 zugewandten Ende weist der Hohlzylinder 14 einen radial nach innen gezogenen Boden 16 auf.In the axially adjoining section of the housing 10 with a larger diameter, a hollow cylinder 14 made of a low-friction plastic is also fitted. The inner diameter of the two sections of the housing 10 and the inner diameter of the hollow cylinder 14 are selected such that the hollow cylinder 14 radially overlaps the magnetic ring 12 only on its outer circumference. At the end facing the magnetic ring 12, the hollow cylinder 14 has a radially inwardly drawn bottom 16.

Der Hohlzylinder 14 und der Magnetring 12 werden koaxial von einer Schaltachse 20 durchsetzt. Auf das obere Ende der aus Stahl bestehenden Schaltachse 20 ist ein Bedienungsknopf 22 aus Kunststoff unlösbar aufgegossen. Im Bereich des Hohlzylinders 14 ist auf die Schaltachse 20 eine Taumelscheibe 24 aus einem ferromagnetischen Material spielfrei aufgeschoben. Die Taumelscheibe 24 ragt mit einem axialen Ansatz 26 in den Magnetring 12. Hülsen 28 und 30 sind oberhalb und unterhalb der Taumelscheibe 24 auf die Schaltachse 20 aufgeschoben und werden durch einen in eine Umfangsnut am unteren Ende der Schaltachse 20 eingesetzten Sprengring axial auf der Schaltachse festgelegt. Dadurch ist auch die Taumelscheibe 24 auf der Schaltachse 20 axial festgelegt.The hollow cylinder 14 and the magnetic ring 12 are coaxially penetrated by a switching axis 20. An operating button 22 made of plastic is cast onto the upper end of the switching shaft 20 made of steel. In the area of the hollow cylinder 14, a swash plate 24 made of a ferromagnetic material is pushed onto the switching axis 20 without play. The swash plate 24 projects with an axial extension 26 into the magnetic ring 12. Sleeves 28 and 30 are pushed above and below the swash plate 24 onto the switching axis 20 and are axially fixed on the switching axis by a snap ring inserted into a circumferential groove at the lower end of the switching axis 20 . As a result, the swash plate 24 is axially fixed on the switching axis 20.

Ein mit dem Gehäuse 10 verschraubter Deckel 32 verschließt an der oberen Stirnfläche den Hohlzylinder 14 und läßt nur eine zentrische Öffnung 34 frei, durch die die Schaltachse 20 und die Hülse 28 mit radialem Spiel durchtreten.A screwed to the housing 10 cover 32 closes the hollow cylinder 14 on the upper end face and leaves only one central opening 34 through which the switching axis 20 and the sleeve 28 pass with radial play.

Die Taumelscheibe 24 ist an ihrem Außenumfang in Axialrichtung ballig abgerundet und weist im Bereich ihres )größten Durchmessers nur ein geringes radiales Spiel gegenüber dem Hohlzylinder 14 auf. Die vom Magnetring 12 abgewandte Fläche der Taumelscheibe 24 fällt von innen gegen den Rand hin schräg ab.The swash plate 24 is rounded on its outer circumference in the axial direction and has only a slight radial play in relation to the hollow cylinder 14 in the area of its largest diameter. The surface of the swash plate 24 facing away from the magnetic ring 12 slopes away from the inside towards the edge.

An der unteren Stirnfläche des Gehäuses 10 ist eine Kulissenscheibe 36 angebracht. Vorzugsweise ist die Kulissenscheibe 36 mit dem Gehäuse 10 verschraubt, so daß sie lösbar und austauschbar ist. Zentrisch in der Kulissenscheibe 36 ist eine Schaltweg-Kulissenöffnung 38 vorgesehen, die von der Schaltachse 20 und der Hülse 30 durchsetzt wird. In dem in Figur 2 dargestellten Aus-. führungsbeispiel ist die Kulissenöffnung 38 für einen Vierweg-Schalthebel ausgebildet. Die Kulissenöffnung 38 weist vier im Winkel um jeweils 90° gegeneinander versetzte Auswölbungen 40 auf, in welche die Schaltachse 20 mit der Hülse 30 hineinbewegt werden kann. Jeder Auswölbung 40 ist ein Steuerelement, z.B. ein Mikroschalter, zugeordnet, der durch die Hülse 30 betätigt wird, wenn diese in die jeweilige Auswölbung 40 bewegt wird.A link plate 36 is attached to the lower end face of the housing 10. The link plate 36 is preferably screwed to the housing 10 so that it is detachable and replaceable. A switching path link opening 38 is provided centrally in the link plate 36, through which the switching axis 20 and the sleeve 30 pass. In the Aus shown in Figure 2. exemplary embodiment, the link opening 38 is formed for a four-way shift lever. The link opening 38 has four bulges 40 offset at an angle of 90 ° to one another, into which the switching axis 20 with the sleeve 30 can be moved. Each bulge 40 is a control, e.g. a microswitch, assigned, which is actuated by the sleeve 30 when it is moved into the respective bulge 40.

Wird der Schalthebel nicht betätigt, so wird er in seine Grundstellung mit koaxialer Ausrichtung der Schaltachse 20 dadurch rückgestellt, daß die ferromagnetische Taumelscheibe 24 durch den Permanent-Magnetring 12 angezogen wird. Die Rückstellkraft des Schalthebels wird dabei im wesentlichen durch die Magnetkraft des Magnetringes 12 bestimmt. Eine weitere Abstimmung der Rückstellkraft ist möglich durch die Wahl des Durchmessers der Taumelscheibe 24 in bezug auf den Innendurchmesser des Magnetringes 12, d.h. durch die radiale Überlappung von Taumelscheibe 24 und Magnetring 12, die den für den Magnetfluß zur Verfügung stehenden Querschnitt bestimmt. Schließlich ist noch eine Abstimmung der Magnetkraft durch die axiale Dicke des Bodens 16 des Hohlzylinders 14 möglich. Dieser Boden 16 wirkt als Trennscheibe zwischen dem Magnetring 12 und der Taumelscheibe 24 und bestimmt den den magnetischen Fluß schwächenden Spalt zwischen diesen.If the shift lever is not actuated, it is reset to its basic position with the coaxial alignment of the shift axis 20 in that the ferromagnetic swash plate 24 is attracted by the permanent magnet ring 12. The restoring force of the shift lever is essentially determined by the magnetic force of the magnetic ring 12. A further adjustment of the restoring force is possible through the choice of the diameter of the swash plate 24 in relation to the inside diameter of the magnetic ring 12, i.e. due to the radial overlap of swash plate 24 and magnetic ring 12, which determines the cross section available for the magnetic flux. Finally, the magnetic force can also be matched by the axial thickness of the base 16 of the hollow cylinder 14. This base 16 acts as a separating disc between the magnetic ring 12 and the swash plate 24 and determines the gap between them which weakens the magnetic flux.

Zur Betätigung des Schalthebels kann die Schaltachse 20 mittels des Bedienungsknopfes 22 manuell aus.der koaxialen Grundstellung gegen die magnetische Rückstellkraft gekippt werden. Das radiale Spiel der Hülse 28 in der Öffnung 34, das radiale Spiel des Ansatzes 26 der Taumelscheibe 24 in dem Magnetring 12 und das radiale Spiel der Hülse 30 in dem Boden des Gehäuses 10 sind so gewählt, daß dadurch die Kippbewegung der Schaltachse 20 nicht behindert wird. Die Kippbewegung wird daher ausschließlich dadurch begrenzt, daß die Schaltachse 20 mit ihrer Hülse 30 mit der Kulissenöffnung 38 der Kulissenscheibe 36 in Berührung kommt.To actuate the shift lever, the shift axis 20 can be manually tilted out of the coaxial basic position against the magnetic restoring force by means of the control button 22. The radial play of the sleeve 28 in the opening 34, the radial play of the neck 26 of the swash plate 24 in the magnetic ring 12 and the radial play of the sleeve 30 in the bottom of the housing 10 are selected so that the tilting movement of the switching axis 20 is not hindered thereby becomes. The tilting movement is therefore limited only in that the switching axis 20 comes into contact with its sleeve 30 with the link opening 38 of the link plate 36.

Schaltweg und Schaltrichtungen des Schalthebels sind daher durch die Auswölbungen 40 der Kulissenöffnung 38 bestimmt.Shift travel and shift directions of the shift lever are therefore determined by the bulges 40 of the link opening 38.

Die ballige Wölbung des Außenumfangs der Taumelscheibe 24 ist so gewählt, daß die Taumelscheibe 24 sowohl in der koaxialen Grundstellung als auch in jeder Kippstellung mit minimalem radialem Spiel durch den Hohlzylinder 14 geführt wird. Durch die Abschrägung der oberen Fläche der Taumelscheibe 24 wird erreicht, daß diese bei maximalem Kippwinkel im wesentlichen parallel an dem Deckel 32 anliegt. Dadurch ist eine optimale Platzausnützung und eine minimale axiale Bauhöhe gewährleistet.The spherical curvature of the outer circumference of the swash plate 24 is selected such that the swash plate 24 is guided through the hollow cylinder 14 with minimal radial play both in the coaxial basic position and in each tilted position. The beveling of the upper surface of the swash plate 24 ensures that it lies essentially parallel to the cover 32 at the maximum tilt angle. This ensures optimal use of space and a minimal axial height.

Bohrungen 42 im Deckel 32 und mit diesen fluchtende Längsnuten 44 in der äußeren Mantelfläche des Gehäuses 10 und der Kulissenscheibe 36 dienen zur Befestigung des Schalthebels mittels Gewindebolzen.Bores 42 in the cover 32 and with these aligned longitudinal grooves 44 in the outer lateral surface of the housing 10 and the link plate 36 are used to fasten the shift lever by means of threaded bolts.
