Description

Die Erfindung betrifft eine Mehrbereichsschalteinrichtung mit einer umlaufenden Schaltscheibe, die in der Drehzahl oder dem Zeitbereich über ein mechanisches Umschaltgetriebe mittels eines, mit dem Umschaltgetriebe gekoppelten, koaxial zur Schaltscheibe angeordneten Drehknopf umgeschaltet werden kann, mit auf der Schaltscheibe angeordneten Schaltreitern zur Betätigung einer Schaltanordnung, wobei die Schaltreiter anhand von zeitbereichsbezogenen Skaleneinteilungen eines Zifferblattes, das auf der Vorderseite der Zeitscheibe angeordnet ist, programmiert werden können und bei der mit der Betätigung des Drehknopfes auch eine drehzahl- und zeitbereichsbezogene Umschaltung der Skaleneinteilung auf dem Zifferblatt bewirkt wird.The invention relates to a multi-range switching device with a rotating switching disc, which can be switched in the speed or the time range via a mechanical changeover gear by means of a rotary knob which is coupled to the switching gear and is arranged coaxially to the switching disc, with switching tabs arranged on the switching disc for actuating a switching arrangement, whereby the shift tabs can be programmed on the basis of time range-related graduations of a dial, which is arranged on the front of the time slice, and which, when the rotary knob is actuated, also causes the dial division on the dial to be switched over in terms of speed and time range.

Für derartige Einrichtungen, wie Schaltuhren oder Programmschaltgeräte ist es aus anwendungstechnischen, rationellen und wirtschaftlichen Gründen zweckmässig und vorteilhaft, den jeweiligen anwendungsbedingten Zeitbereich bzw. die Drehzahl einer Schaltscheibe, insbesondere innerhalb des dort üblichen Tages-, Wochen-, Monats- oder Jahresprogrammzeitbereichs anwählen zu können. Dabei soll sichergestellt sein, dass die an derartigen Einrichtungen vorhandenen Mittel und Elemente hierfür ausreichend sind.For such devices, such as time switches or program switching devices, it is expedient and advantageous for application-related, rational and economic reasons to be able to select the respective application-related time range or the speed of a switching disc, in particular within the daily, weekly, monthly or annual program time range there . It should be ensured that the means and elements available at such facilities are sufficient for this.

Es ist bekannt zur Erfüllung dieser Erfordernisse, insbesondere bei einer synchronmotorisch angetriebenen Schaltuhr, mit einem dort vorgesehenen Tages- und Wochenprogrammzeitbereich zwischen dem Antrieb und der Schaltscheibe ein mechanisches Umschaltgetriebe vorzusehen, mit welchem die Drehzahl der Schaltscheibe von 1 U/24h auf 1 U/Woche und umgekehrt verändert werden kann. Es ist dort jedoch erforderlich, dass zusätzlich zu dieser Getriebeumschaltung und unabhängig von dieser auf der Schaltscheibe ein Zifferblatt gewechselt d.h. auf den jeweiligen Zeitbereich abgestimmt werden muss (DE-A-2835518).It is known to meet these requirements, in particular in the case of a synchronous motor-driven time switch, with a daily and weekly program time range provided there between the drive and the switching disk, to provide a mechanical changeover gear with which the speed of the switching disk from 1 U / 24h to 1 U / week and vice versa can be changed. However, it is necessary there that in addition to this transmission changeover and independently of it, a dial on the switching disc has to be changed, i.e. must be coordinated with the respective time range (DE-A-2835518).

Diese bekannte Schaltuhr ist nicht frei von Bedienungsfehlern, insbesondere durch die dort voneinander getrennte Handhabung vom Getriebeumschaltung und Zifferblattwechsel. Ausserdem ist es dort relativ kompliziert, wenn die derart drehzahlumschaltbare Schaltscheibe zusätzlich zu einem, die Tageszeit anzeigenden Zeigerwerk auf der Schaltuhr eingestellt werden muss.This known time switch is not free from operating errors, in particular due to the separate handling of gear change and dial change there. In addition, it is relatively complicated there if the switching disk which can be switched over in this way has to be set on the time switch in addition to a pointer mechanism which indicates the time of day.

Aus der US-A-3 454 909 ist ein Zeitrelais bekanntgeworden, bei welchem die Umschaltung des Zeitbereichs durch ein Verdrehen einer Vorwahleinrichtung, welche mittels einem schraubengangförmigen Teil ein Antriebsritzel axial verschiebt, sodass dieses mit Antriebsrädern mit zueinander unterschiedlichen Drehzahlen in Eingriff gebracht werden kann. Dabei ist die Vorwahleinrichtung über einen Zahnradeingriff mit einer Zifferblattscheibe gekoppelt, sodass mit der Drehzahlvorwahl gleichzeitig auch eine Umschaltung des der Drehzahl entsprechenden Zeitbereichs erfolgt, der in einer Öffnung auf der Vorderseite des Zeitrelais angezeigt wird.From US-A-3 454 909 a timing relay has become known, in which the switching of the time range by rotating a preselection device, which axially displaces a drive pinion by means of a screw-shaped part, so that this can be brought into engagement with drive wheels at different speeds. The preselection device is coupled to a dial by means of a gear engagement, so that the speed preselection also switches over the time range corresponding to the speed, which is displayed in an opening on the front of the time relay.

Diese Einrichtung erfüllt wohl im allerwesentlichsten die eingangs angestrebten Erfordernisse, die Vorwahleinrichtung ist jedoch hier relativ umständlich zu bedienen, ausserdem ist ein Hilfswerkzeug zu dessen Bedienung erforderlich.This device fulfills most of all the requirements initially desired, but the preselection device is relatively cumbersome to use here, and an auxiliary tool is also required to operate it.

Auch das, aus der GB-A-1 267 784 bekanntgewordene, Zeitrelais mit einer koaxialen Drehzahl- und Zeitbereichsvorwahl mittels eines Drehknopfes bringt hier keinen Vorteil gegenüber dem bereits erwähnten Stand der Technik. Dort erfolgt die Umschaltung der Drehzahl mittels eines Schwenkgetriebes, wobei die Anzeige des der gewählten Drehzahl entsprechenden Zeitbereichs über einen Pfeil erfolgt, der auf den, auf dem Drehknopf aufgedruckten Zeitbereich zeigt. Diese Vorwahleinrichtung lässt sich, wie auch die unmittelbar zuvor geschilderte Vorwahleinrichtung nicht ohne weiteres auf eine Mehrbereichsschalteinrichtung mit einer Schaltscheibe mit programmierbaren Schaltreitern übertragen.Also the time relay, which has become known from GB-A-1 267 784, with a coaxial speed and time range preselection by means of a rotary knob does not bring any advantage over the prior art already mentioned here. There, the speed is switched by means of a swivel gear, the time range corresponding to the selected speed being indicated by an arrow pointing to the time range printed on the rotary knob. This preselection device, like the preselection device described immediately above, cannot easily be transferred to a multi-range switching device with a switching disk with programmable switching tabs.

Der Erfindung liegt die Aufgabe zugrunde, eine Mehrbereichsschalteinrichtung der eingangs genannten Art zu schaffen, bei der die Schaltscheibe in ihrer örtlichen Lage hinsichtlich ihres Eingriffsbereichs zu einer Schaltanordnung nicht verändert wird. Ausserdem soll sichergestellt sein, dass durch den Drehzahl- oder Zeitbereichswechsel eine klare und genau bezogene Einstellung zu einem vorgesehenen oder vorhandenen analog anzeigenden Zeigerwerk gewährleistet ist.The invention has for its object to provide a multi-range switching device of the type mentioned, in which the switching disc is not changed in its local position with respect to its engagement area to a switching arrangement. In addition, it should be ensured that the change in speed or time range ensures a clear and precisely related setting to an intended or existing analogue pointer movement.

Diese Aufgabe wird mit den Merkmalen im kennzeichnenden Teil des Patentanspruchs gelöst.This object is achieved with the features in the characterizing part of the patent claim.

Some embodiments are shown in the drawing and are explained in more detail below. Show it
  • Fig. 1 is a sectional view through a device with a switching disc, with an axially acting coupling device for changing the speed of the switching disc and with a radially acting change in the speed-dependent dial display.
  • Fig. 2 is a sectional view through a device with a switching disc and with a centrally operable, rotatable coupling device for changing the speed and the dial display for a switching disc and
  • 3 shows a plan view of a device according to FIGS. 1 and 2.

Bei einer Einrichtung, wie sie die Fig. 1 zeigt, ist die Schaltscheibe 1 auf einem Lagerbolzen 3 gelagert. Der Lagerbolzen 3 ist bei dieser Ausführung nicht drehbar, sondern die Schaltscheibe 1 dreht sich auf dem Lagerbolzen 3. 6 und 7 bezeichnen zwei Antriebswellen, wobei die Antriebswelle 6 1 U/24h und die andere Antriebswelle 7 1 U/Woche ausführen kann. Die Antriebswelle 6 ist mit einem Kupplungsteil 8 und die Antriebswelle 7 mit einem Kupplungsteil 9 versehen. Die nicht ortsveränderliche Schaltscheibe 1 ist sowohl auf der Vorderseite 25, wie auf der Unterseite 26 mit einem lückenförmigen Kupplungsteil 10 versehen. Die Antriebswellen 6 und 7 sind axial verschiebbar. Die axiale Verschiebung kann dort durch einen scheibenförmig ausgebildeten Drehknopf 27 erfolgen, der mit der Schaltscheibe 1 umläuft, jedoch in einem gewissen Winkel zu dieser verstellbar ist.In a device as shown in FIG. 1, the switching disc 1 is mounted on a bearing pin 3. The bearing pin 3 is not rotatable in this embodiment, but the switching disc 1 rotates on the bearing pin 3. 6 and 7 denote two drive shafts, the drive shaft 6 1 U / 24h and the other drive shaft 7 1 U / week. The drive shaft 6 is provided with a coupling part 8 and the drive shaft 7 with a coupling part 9. The non-changeable switching disc 1 is provided with a gap-shaped coupling part 10 both on the front 25 and on the underside 26. The drive shafts 6 and 7 are axially displaceable. The axial displacement can take place there by means of a disk-shaped rotary knob 27 which rotates with the switching disk 1, but is adjustable at a certain angle to the latter.

Durch die relative Verdrehung des Drehknopfes 27 zur Schaltscheibe 1 wird nicht nur die jeweilige Antriebswelle 6, 7 durch axiales Verschieben mit der Schaltscheibe 1 gekuppelt, indem die betreffenden Kupplungsteile 8, 9 mit den entsprechend diesen benachbarten Kupplungsteilen 10 auf der Schaltscheibe 1 in Eingriff kommen, sondern es werden dadurch auch zwei Skaleneinteilungen eines Zifferblattes 12, die auf der Vorderseite 25 in zueinander verschiedenen Durchmessern angeordnet sind, wechselseitig abgedeckt oder freigestellt.As a result of the relative rotation of the rotary knob 27 relative to the switching disk 1, not only is the respective drive shaft 6, 7 coupled to the switching disk 1 by axial displacement, in that the coupling parts 8, 9 concerned engage with the coupling parts 10 on the switching disk 1 which are adjacent thereto, instead, two scale divisions of a dial 12, which are arranged on the front side 25 in different diameters, are alternately covered or exempted.

Bei einer Einrichtung, wie sie die Fig. 2 zeigt, ist die Schaltscheibe 1 auf dem Lagerbolzen 3 gelagert. Auf der Schaltscheibe 1 ist ein scheibenförmig ausgebildeter Drehknopf 27 koaxial gelagert. Der Drehknopf 27 läuft mit der Schaltscheibe 1 um und ist zu dieser in einem gewissen Winkel verdrehbar. Sowohl die Schaltscheibe 1, als auch der Drehknopf 27 sind dort nicht ortsveränderlich.In a device as shown in FIG. 2, the switching disc 1 is mounted on the bearing pin 3. On the switching disc 1, a disc-shaped rotary knob 27 is mounted coaxially. The rotary knob 27 rotates with the switching disc 1 and can be rotated at a certain angle to the latter. Both the switching disc 1 and the rotary knob 27 cannot be moved there.

Für den Antrieb der Schaltscheibe 1 ist eine Getriebeanordnung mit einem Getrieberad 21 und einem Getrieberitzel 22 vorgesehen, die axial verstellbar ist und mit dem Drehknopf 27 zum Zwecke der Drehzahländerung axial verstellt werden kann. Je nach Drehzahlvorwahl wird dort das Getrieberad 21 oder das Getrieberitzel 22 mit einem der Zahnkränze 28 auf der Schaltscheibe 1 in Eingriff gebracht. Auf der Vorderseite 25 werden vom Drehknopf 27 mittels Öffnungen 32 in der Scheibe 31 Skaleneinteilungen in zueinander verschiedenem Durchmesser auf einem Zifferblatt 12 freigestellt. 2 bezeichnet einen Schaltreiter und 5 eine Schaltanordnung.For driving the switching disc 1, a gear arrangement with a gear wheel 21 and a gear pinion 22 is provided, which is axially adjustable and can be adjusted axially with the rotary knob 27 for the purpose of changing the speed. Depending on the speed preselection, the gearwheel 21 or the gear pinion 22 is brought into engagement with one of the sprockets 28 on the switching disc 1 there. On the front side 25, graduations in different diameters on a dial 12 are released from the rotary knob 27 by means of openings 32 in the disk 31. 2 denotes a switching tab and 5 a switching arrangement.

In der Fig. 3 ist sichtbar, wie der Drehknopf 27 auf der Schaltscheibe 1, relativ zu dieser drehbar angeordnet ist. 30 bezeichnet eine, durch die Scheibe 31 des Drehknopfes 27 freigestellte, Skaleneinteilung, insbesondere eine 24h-Einteilung. Auf der Scheibe 31 sind zu diesem Zweck Öffnungen 32 vorgesehen, die über den, auf der Schaltscheibe 1 angeordneten Skaleneinteilungen 30 stehen, und die, je nach Einstellung des Drehknopfs 27 abgedeckt oder freigestellt werden.3 shows how the rotary knob 27 is arranged on the switching disk 1 so that it can rotate relative to the latter. 30 denotes a scale division, in particular a 24-hour division, released by the disk 31 of the rotary knob 27. For this purpose, openings 32 are provided on the disk 31, which are above the graduations 30 arranged on the switching disk 1 and which, depending on the setting of the rotary knob 27, are covered or exposed.
