Abstract

1. Switch-position indicator with a tubular casing (1) forming at one end an opening (3) into which symbol surface elements indicating an operational state are pivotably movable by drive means, characterised in that eccentrically transversely to the longitudinal axis of the casing there is arranged in the region of the opening (3) a pivot shaft (7) for a disc (9) carrying a symbol surface, this disc (9) being pivotably movable between a first position and a second position and being directed substantially at right angles to the longitudinal axis of the casing in the first position and substantially parallel to the said axis in the second position.

Description

Die vorliegende Erfindung bezieht sich auf einen Schaltstellungsmelder mit rohrförmigem Mantel, der an einem Ende eine Öffnung bildet, in die einen Betriebszustand signalisierende Symbolflächen durch Antriebsmittel schwenkbar sind.The present invention relates to a switch position detector with a tubular jacket, which forms an opening at one end, into which symbol areas signaling an operating state can be pivoted by drive means.

Derartige Schaltstellungsmelder sind z.B. aus der DE-B-1018338 bekannt. Die symboltragende Scheibe ist rechtwinklig zur Mantellängsachse und drehbar um diese gelagert. Der Nachteil dieser Vorrichtung besteht darin, dass sie ohne Vergrösserung des Manteldurchmessers nur wenige Symbole von ausreichend sichtbarer Flächenausdehnung zulässt und von hinten nicht ohne Schattenwurf der Drehachse beleuchtbar ist.Such switch position detectors are e.g. known from DE-B-1018338. The symbol-bearing disc is mounted at right angles to the longitudinal axis and rotatable around it. The disadvantage of this device is that, without increasing the jacket diameter, it allows only a few symbols of sufficiently visible surface area and cannot be illuminated from behind without casting a shadow on the axis of rotation.

Die gleichen Nachteile weisen jene auf die in der DE-C-956702 und GB-A-730591 gezeigt sind und bei denen die Symbolflächen Kugelflächenabschnitte sind, deren Drehachse die Mantellängsachse rechtwinklig schneidet.The same disadvantages have those which are shown in DE-C-956702 and GB-A-730591 and in which the symbol surfaces are spherical surface sections whose axis of rotation intersects the longitudinal axis of the jacket at right angles.

Die vorliegende Erfindung stellt sich die Aufgabe, einen Schaltstellungsmelder der genannten Art derart zu verbessern, dass er bei kleinem Manteldurchmesser eine möglichst grosse Anzeigefläche aufweist und zudem die Möglichkeit zum Signalisieren möglichst vieler Symbole eröffnet.The object of the present invention is to improve a switch position detector of the type mentioned in such a way that it has the largest possible display area with a small jacket diameter and also opens up the possibility of signaling as many symbols as possible.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass aussermittig quer zur Mantellängsachse im Bereich der Öffnung eine Schwenkwelle für eine eine Symbolfläche tragende Scheibe angeordnet ist, welche Scheibe zwischen einer ersten und einer zweiten Stellung schwenkbar und in der ersten Stellung im wesentlichen rechtwinklig und in der zweiten Stellung im wesentlichen parallel zur Mantellängsachse orientiert ist.According to the invention, this object is achieved in that a pivot shaft for a disk bearing a symbol surface is arranged eccentrically transversely to the longitudinal axis of the jacket, which disk can be pivoted between a first and a second position and in the first position essentially at right angles and in the second position is oriented essentially parallel to the longitudinal axis of the jacket.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf einen Schaltstellungsmelder mit entfernter Frontrahmenverkleidung und
  • Fig. 2 einen Schnitt längs der Linie 11-11 wobei eine der ein Symbol tragenden Scheiben in der ersten Stellung gezeigt ist.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
  • Fig. 1 is a plan view of a switch position detector with the front frame panel removed and
  • Fig. 2 shows a section along the line 11-11, wherein one of the symbol-bearing disks is shown in the first position.

Der Schaltstellungsmelder weist einen im Querschnitt quadratischen Mantel 1 auf, der an einem hinteren Ende durch eine Platte 2 geschlossen ist und am vorderen Ende eine Öffnung 3 bildet. Das vordere Mantelende ist mit einem flanschartigen Rand 4 versehen, auf den ein die Randzone der Öffnung 3 ausblendender Rahmen 5 aufgesteckt ist. Auf dem flanschartigen Rand 4 ist auf jeder seiner vier Seiten je ein Schwenklagerpaar 6 angeordnet. In denen je eine Schwenkwelle 7 gelagert ist. Mittels eines Steges 8 ist an jeder Schwenkwelle 7 eine Scheibe 9 befestigt und der Steg 6 ist derart gestaltet, dass wenn sich die Scheibe 9 ihrer in Fig. 1 gezeigten Stellung parallel zur entsprechenden Seitenwand des Mantels 1 befindet, zwischen dieser Seitenwand und der Scheibe 9 ein Zwischenraum 10 besteht. Weiter sind Länge und Breite der Scheiben 9 so gewählt, dass jede Scheibe 9 in der zweiten Stellung ausserhalb der anderen Scheiben 9 liegt. Jeder Scheibe 9 ist zum Verschwenken zwischen der ersten und der zweiten Stellung eine Schiebeplatte 11 zugeordnet, die in einer nicht dargestellten, in der entsprechenden Seitenwand angeordneten Schwalbenschwanznut längsverschiebbar gelagert ist und am oberen Ende gegen den Steg 8 anliegt. Das untere Ende der Schiebeplatte 11 ist mit einem Antrieb 12 getrieblich verbunden, der je nach dem zu signalisierenden Betriebszustand die Schiebeplatte 11 nach oben oder nach unten oder gegebenenfalls in eine Zwischenstellung bewegt. In der unteren Hälfte des Mantels 1 ist innenseitig ein Steg 12' eingesetzt, der eine elektrische, von vorne auswechselbare Signallampe (13) trägt, die die lichtdurchlässigen Scheiben 9 durchleuchtet, wenn sie die erste im wesentlichen rechtwinklig zur Mantellängsachse orientierte Stellung einnehmen. Die Scheiben 9 können von unterschiedlicher Farbe sein, so dass insgesamt vier einzelne Farben oder mehrere Mischfarbenkombinationen signalisierbar sind. Durch das Angreifen der Schieberplatte 11 nahe der Schwenkwelle 7 ist für die Schieberplatte 11 ein nur kleiner Verschiebeweg und ein rasches Verschwenken der Scheibe 9 möglich. Obwohl die Schwenkwelle 7 in der selben, zur Mantellängsachse quer orientierten Ebene liegen, können sämtliche Scheiben 9 in die erste Stellung geschwenkt werden, wobei sich ein Teil der Scheiben 9 nur mindestens näherungsweise rechtwinklig zur Mantellängsachse in der ersten Stellung einstellt. Um die visuelle Erkennbarkeit der Anzeige nicht zu stören, blendet der Rahmen 5 den Randbereich der Öffnung 3 bzw. der in der ersten Stellung befindlichen Scheibe 9 aus, wodurch ein Ausfall von schrägem Streulicht der Lampe 13 verhindert wird.The switch position indicator has a jacket 1 with a square cross section, which is closed at a rear end by a plate 2 and forms an opening 3 at the front end. The front jacket end is provided with a flange-like edge 4, onto which a frame 5 which fades out the edge zone of the opening 3 is attached. A pair of swivel bearings 6 is arranged on the flange-like edge 4 on each of its four sides. In each of which a pivot shaft 7 is mounted. A disk 9 is fastened to each pivot shaft 7 by means of a web 8 and the web 6 is designed such that when the disk 9 in its position shown in FIG. 1 is parallel to the corresponding side wall of the casing 1, between this side wall and the disk 9 there is a space 10. Furthermore, the length and width of the disks 9 are selected such that each disk 9 lies outside the other disks 9 in the second position. For pivoting between the first and the second position, each disk 9 is assigned a sliding plate 11, which is mounted so as to be longitudinally displaceable in a dovetail groove (not shown) arranged in the corresponding side wall and abuts against the web 8 at the upper end. The lower end of the sliding plate 11 is operatively connected to a drive 12 which, depending on the operating state to be signaled, moves the sliding plate 11 up or down or, if appropriate, into an intermediate position. In the lower half of the jacket 1, a web 12 'is inserted on the inside, which carries an electrical signal lamp (13) which can be replaced from the front and which illuminates the translucent panes 9 when they assume the first position, which is oriented essentially at right angles to the longitudinal axis of the jacket. The disks 9 can be of different colors, so that a total of four individual colors or several mixed color combinations can be signaled. By engaging the slide plate 11 near the pivot shaft 7, only a small displacement path and a rapid pivoting of the disk 9 is possible for the slide plate 11. Although the pivot shaft 7 lies in the same plane, oriented transversely to the longitudinal axis of the jacket, all of the disks 9 can be swiveled into the first position, with some of the disks 9 only adjusting at least approximately at right angles to the longitudinal axis of the jacket in the first position. In order not to disturb the visual recognizability of the display, the frame 5 hides the edge region of the opening 3 or the pane 9 located in the first position, thereby preventing a failure of oblique scattered light from the lamp 13.

In der einfachsten Ausführungsform kann der Schaltstellungsmelder mit nur einer Scheibe 9 ausgeführt werden, welche lediglich zwischen der ersten und der zweiten Stellung verschwenkbar ist. Vorzugsweise wird er aber mit mehreren schwenkbaren Scheiben ausgeführt, die gegebenenfalls zudem eine Mittelstellung zwischen der ersten und zweiten Stellung einnehmen können. Der Mantel 1 kann eine beliebige Querschnittsform aufweisen, wobei aber ein rechteckiger oder quadratischer Querschnitt die grösst möglichen Symbolfläche bei geringstem Manteldurchmesser erreicht. Es ist auch möglich, anstelle lichtdurchlässiger Scheiben 9 lichtundurchlässige zu verwenden, wobei die Lampe 13 entfallen kann.In the simplest embodiment, the switch position indicator can be designed with only one disk 9, which can only be pivoted between the first and the second position. However, it is preferably designed with a plurality of pivotable disks, which, if necessary, can also assume a central position between the first and second positions. The jacket 1 can have any cross-sectional shape, but a rectangular or square cross-section achieves the largest possible symbol area with the smallest jacket diameter. It is also possible to use opaque disks instead of translucent disks 9, it being possible to dispense with the lamp 13.
