    • Die Bedieneinheit 2 besteht aus einem eine Bedienblende bildenden Blechabschnitt 4 mit einer Öffnung (Formloch) 6, einem in die Öffnung (Formloch) 6 einsetzbaren Skalentopf 8, einem im Skalentopf verschieb- und drehbaren Versenkknebel 10 und einer auf dem Skalentopf 8 aufnehmbaren Überwurfmutter 12, die mit Ausnahme der Bedienblende alle Formteile, insbesondere Kunststoffformteile sind. The operating unit 2 consists of a control panel forming a Sheet metal section 4 with an opening (form hole) 6, a in the opening (shape hole) 6 usable scale pot 8, a sliding in the scale pot and rotatable countersunk knob 10 and a receiving on the scale pot 8 union nut 12, with the exception of the control panel all molded parts, in particular Plastic moldings are.

    Die Öffnung (Formloch) 6 ist kreisförmig mit 4 nach innen weisenden Vorsprüngen (Zähnen) 14 ausgebildet.The opening (molding hole) 6 is circular with 4 inwards pointing projections (teeth) 14 formed.

    Der Skalentopf 8 besitzt einen topfförmigen Teil 16 mit einem zylindrischen Hohlschaft 18 und einem Boden 20, in dem sich eine zentrische Öffnung 22 befindet, durch den die Schaltwelle eines nichtdargestellten Drehschalters, beispielsweise Energiereglers, hindurchsteckbar ist. Die offene Seite des Hohlschaftes 18 ist durch eine nach außen weisende ringförmige Schulter 26 abgeschlossen.The scale pot 8 has a cup-shaped part 16 with a cylindrical hollow shaft 18 and a bottom 20 in which a central opening 22 is located, through which the switching shaft an unillustrated rotary switch, for example Energiereglers, is plugged through. The open side of the Hollow shaft 18 is by an outwardly facing annular Shoulder 26 completed.

    Im Boden 20 ist ein Kreisring 24 angeordnet, der beim Aufstecken des Versenkknebels 10 auf die nichtdargestellte Schaltwelle den Aufsteckweg begrenzt, um ein sicheres Fluchten der vorzugsweise kugelförmig gewölbten Deckflächen des Versenkknebels 10 und der Ringschulter 26 zu einer einheitlichen Deckfläche zu garantieren.In the bottom 20, a circular ring 24 is arranged, which when plugging of the countersunk knob 10 on the not shown Shift shaft limits the Aufsteckweg to a safe alignment the preferably spherically curved top surfaces of the Retractable knob 10 and the annular shoulder 26 to a uniform Guarantee deck area.

    An der Außenwandung 28 des Hohlschaftes 18 erstrecken sich von der Schulter 26 in Richtung Boden 20 kurze Erhebungen (Rippen) 30, die zwischen die Vorsprünge (Zähne) 14 der Öffnung 6 einführbar sind. Seitlich gesehen, zeigen sich die Erhebungen (Rippen) 30 als U-förmige Stege mit achsparallelen Schenkeln 32 und von der Schulter 26 wegweisenden Querstegen 34.On the outer wall 28 of the hollow shaft 18 extend from the shoulder 26 in the direction of the ground 20 short elevations (Ribs) 30, between the projections (teeth) 14 of the opening 6 are insertable. Seen from the side, the surveys show (Ribs) 30 as U-shaped webs with paraxial Legs 32 and the shoulder 26 pioneering transverse webs 34th

    Auf einem von den Querstegen 34 entfernten koaxialen Kreisbogen befinden sich an der Außenwandung 28 des Hohlschaftes 18 zwei zueinander um 180 Grad versetzte kurze (etwa einem Viertelkreis entsprechende) Schraubbahnen 36, die jeweils aus einem gegen den Kreisbogen geneigten längeren Abschnitt 38 und einem mit dem Kreisbogen zusammenfallenden schulternäheren kürzeren Abschnitt 40 bestehen, der an seinem freien Ende in einen achsparallelen Abschnitt 42 übergeht, der sich wiederum in Richtung Schulter 26 erstreckt. Die beiden Enden der Schraubbahnen 36 sind darüber hinaus mit einem sich pfeilförmig in Richtung Boden 20 erstreckenden Führungssteg 44 verbunden.On a distance from the transverse webs 34 coaxial arc are located on the outer wall 28 of the hollow shaft 18 two 180 degrees offset to each other short (about one Quarter circle corresponding) Schraubbahnen 36, each off a curved against the circular arc longer portion 38th and a shoulder closer to the arc shorter section 40 exist, at its free end in an axis-parallel section 42 passes, which in turn extends in the direction of the shoulder 26. The two ends of the Screw ties 36 are also with an arrow-shaped connected in the direction of the bottom 20 extending guide web 44.

    Auf einem die Abschnitte 42 schneidenden koaxialen Kreisbogen trägt die Außenwandung 28 des Hohlschaftes 18 zwei zueinander um 180 versetzte Noppen 46, die zu den Abschnitten 42 etwa um 90 Grad versetzt sind.On a section 42 cutting coaxial arc the outer wall 28 of the hollow shaft 18 carries two to each other by 180 staggered nubs 46, to the sections 42 about 90 degrees are offset.

    Schließlich weist der Hohlschaft 18 zwei gegenüberliegende seitliche Durchbrüche 48 auf, die sich unterhalb der pfeilförmigen Führungsstege 44 achsparallel bis an den Boden 20 heran erstrecken.Finally, the hollow shaft 18 has two opposite lateral openings 48 on, extending below the arrow-shaped Guide webs 44 axially parallel to the floor 20 extend to.

    Die Überwurfmutter 12 besitzt einen Hohlschaft 52, von dessen zur Bedienblende weisendem einen Ende sich vier um jeweils 90 Grad versetzte relativ starre Anlageflächen 54 schräg nach außen erstrecken, zwischen denen jeweils drei federnde Anlageflächen 56 angeordnet sind, die sich bei etwa gleicher Länge von demselben Hohlschaftende schräg nach außen wegerstrekken, jedoch unter einem etwas stärker zur Längsachse geneigten Winkel. Alternativ hierzu können die starren Anlageflächen 54 bei gleicher Neigung wie die federnden Anlageflächen auch axial zurückgesetzt angeordnet sein. In der Draufsicht zeigt sich die Gesamtheit der Anlageflächen 54 und 56 blütenkranzartig.The union nut 12 has a hollow shaft 52, of which to the control panel pointing one end four by 90 each Degree displaced relatively rigid contact surfaces 54 obliquely extend outside, between each of which three resilient contact surfaces 56 are arranged, which are approximately the same length extending obliquely outwards from the same hollow shaft end, but under a slightly more inclined to the longitudinal axis Angle. Alternatively, the rigid contact surfaces 54 at the same inclination as the resilient contact surfaces also be arranged axially reset. In the plan view shows the entirety of the contact surfaces 54 and 56 like a flower crown.

    Von der Innenwandung 58 der Überwurfmutter 12 erheben sich entlang eines koaxialen Kreisbogens vier um jeweils 90 Grad versetzte Winkelstege 60, deren erste Schenkel 62 kreisbogenparallel und deren zweite Schenkel 64 achsparallel verlaufen. Alle Winkelstege 60 öffnen sich in derselben Richtung, in der sich die durch die Schraubbahnabschnitte 40 und 42 des Skalentopfes 8 gebildeten Winkel öffnen.
    Die Wirkungsweise ist folgende:    From the inner wall 58 of the union nut 12 rise along a coaxial arc four offset by 90 degrees each angle webs 60, the first leg 62 arc parallel and the second leg 64 extend parallel to the axis. All angle webs 60 open in the same direction in which open the angle formed by the Schraubbahnabschnitte 40 and 42 of the scale pot 8.
    The mode of action is the following:

    Zunächst wird der Skalentopf 8 mit seinem Hohlschaft 18 von der Bedienseite her in die Öffnung 6 des Blechabschnittes 1 eingeführt, bis die Erhebungen (Rippen) 30 des Hohlschaftes 18 formschlüssig zwischen die Vorsprünge (Zähne) 14 gelangen, um den Skalentopf gegen Verdrehen zu sichern, und schließlich die Schulter 26 an der bedienerzugewandten Oberfläche des Blechabschnittes anliegt, um sowohl als axialer Festanschlag als auch als Dichtung gegen eindringende Flüssigkeiten aller Art zu wirken.First, the scale pot 8 with its hollow shaft 18 of the operating side forth in the opening 6 of the sheet metal section. 1 inserted until the elevations (ribs) 30 of the hollow shaft 18 enter between the projections (teeth) 14 in a form-fitting manner, to secure the scale pot against twisting, and finally the shoulder 26 on the operator facing surface of the Blechabschnittes abuts, both as an axial fixed stop as well as a seal against penetrating liquids of all Way of acting.

    Dann wird die Überwurfmutter 12 von der bedienerabgewandten Seite her mit den Anlageflächen 54 und 56 voran über den Skalentopf 8 geschoben. Sofern dabei ihre Winkelstege 60 nicht von vornherein zwischen die Schraubbahnen 36 und Noppen 46 des Skalentopfes gelangen, werden sie von den pfeilförmigen Führungsstegen 44 dorthin geführt, die zugleich stabilisierende Wirkung haben. Then the union nut 12 is turned away from the operator Side with the contact surfaces 54 and 56 ahead on the scale pot 8 pushed. Unless their angle bars 60 are not from the outset between the screw 36 and nubs 46th of the scale pot, they become of the arrow-shaped Guide webs 44 led there, the same time stabilizing Have effect.

    Anschließend wird die Überwurfmutter 12 gedreht, bis zwei ihrer Winkelstege 60 mit ihrer geschlossenen Seite voran zunächst entlang der geneigten Schraubbahnabschnitte (schraubenförmigen Konturen) 38 gleiten und so einen axialen Vorschub in Richtung der bedienerabgewandten Oberfläche des Blechabschnittes 1 bewirken. Je nach dessen Materialdicke geraten dabei die federnden Anlageflächen 56 früher oder später an den Blechabschnitt 1 und schließlich unter immer stärkere Spannung, deren Niveau erhalten bleibt, wenn sich die beiden Winkelstege 60 entlang der koaxialen Schraubbahnabschnitte 40 bewegen.Subsequently, the union nut 12 is rotated until two of its Angled webs 60 first with their closed side first along the inclined helical sections (helical Contours) 38 slide and so an axial feed in the direction of the user-facing surface of the Blechabschnittes 1 effect. Depending on the material thickness advised while the resilient abutment surfaces 56 sooner or later to the sheet metal section 1 and finally under ever stronger Tension whose level is maintained when the two Angled webs 60 along the coaxial Schraubbahnabschnitte 40th move.

    Die Sicherung dieser axialen Abstützung der federnden Überwurfmutter 12 erfolgt im letzten Drehabschnitt, wenn die achsparallelen zweiten Schenkel 64 der beiden anderen Winkelstege 60 über die beiden Noppen 46 schnappen und sich die bahngeführten Winkelstege 60 mit ihren achsparallelen zweiten. Schenkeln an die achsparallelen Abschnitte 42 der Schraubbahnen 36 anlegen.The assurance of this axial support of the resilient union nut 12 takes place in the last rotary section, when the axially parallel second leg 64 of the two other angle webs 60 over the two nubs 46 snap and the web-guided angle webs 60 with their axis-parallel second. Legs on the axis-parallel sections 42 of the screw tracks 36 create.

    Sollte die Materialdicke des Blechabschnittes 1 besonders groß sein, wird die Auslenkung der federnden Anlageflächen 56 begrenzt, indem sich die relativ starren Anlageflächen 54 an den Blechabschnitt 1 anlegen.Should the material thickness of the sheet metal section 1 special be large, the deflection of the resilient abutment surfaces 56th limited by the relatively rigid contact surfaces 54 at create the sheet metal section 1.

    Nach der rastenden Verspannung des Skalentopfes 8 mit dem das Bedienfeld bildenden Blechabschnitt 1 wird an der Außenseite des Bodens 20 des Skalentopfes 8 ein nichtdargestellter Drehschalter, beispielsweise ein Energieregler, angesetzt und vom Skalentopfinneren her verschraubt.
