AbschlieQbare Sichtblende
5Lockable screen

Die Erfindung bezieht sich auf eine Sichtblende, z.B. für einen Drehantrieb, mit einem Riegel, mit dem ein drehbarer Knebel in einer Position arretierbar ist, wobei die Arretierung mittels Schließmitteln sicherbar ist.The invention relates to a screen, e.g. for a rotary drive, with a latch with which a rotatable knob can be locked in one position, wherein the locking can be secured by means of locking means.
Eine abschließbare Sichtblende der o.g. Art ist im Siemens-Katalog NV 21/1983 Seite 8/2 offenbart. Die Sichtblende dient hier neben der Arretierung auch zur Schaltzustandsanzeige für einen Drehantrieb eines Schaltgeräts, der durch einen Knebel zwischen einer EIN- und AUS-Stellung umschaltbar ist. Eine Sperrscheibe ist auf eine Welle des Drehantriebs aufgesetzt. Das Schaltgerät ist z.B. an einer Schalttafel befestigt, an der frontseitig die Sichtblende angeschraubt ist. In die Sichtblende ist eine Anzeigeplatte eingelegt und darüber der Knebel befestigt. Zur Verriegelung weist die Sperrscheibe randseitig wenigstens eine Ausnehmung auf, in die der Riegel durch Betätigung einer Klappe einrastbar ist, sodaß hierdurch eine Drehbewegung des Knebels bei dieser Stellung verhindert wird. Die Klappe ist durch eine Blattfeder derart vorgespannt, daß der entriegelte Zustand eingehalten wird. Die Klappe kann in umgeschwenkter, d.h. verriegelter Stellung durch ein Vorhängeschloß gehalten werden.A lockable cover of the above type is disclosed in the Siemens catalog NV 21/1983 page 8/2. In addition to locking, the cover also serves to display the switching status for a rotary drive of a switching device that can be switched between an ON and OFF position using a toggle. A locking disk is placed on a shaft of the rotary drive. The switching device is attached to a control panel, for example, to which the cover is screwed on the front. A display plate is inserted into the cover and the toggle is attached above it. For locking, the locking disk has at least one recess on the edge into which the bolt can be engaged by operating a flap, so that a rotary movement of the toggle is prevented in this position. The flap is pre-tensioned by a leaf spring in such a way that the unlocked state is maintained. The flap can be held in the pivoted, i.e. locked, position by a padlock.
im folgenden wird anhand eines Ausführungsbeispiels die Erfindung näher erläutert. Es zeigen:The invention is explained in more detail below using an example embodiment. Shown are:

FIG 2 eine Seitenansicht der Sichtblende nach FIG 1 mit einem aufklappbarem Riegel und Darstellung von
seinem Schwenkmechanismus,
FIG 3 eine weitere Seitenansicht der Sichtblende nach FIG 1.FIG 2 is a side view of the screen according to FIG 1 with a hinged latch and representation of its pivoting mechanism,
FIG 3 is another side view of the screen according to FIG 1.
In FlG 1 ist eine abschließbare Sichtblende 1 dargestellt mit einem in einer Mulde 5 versenkten Riegel 2, der drehbar gelagert und aus der Mulde 5 herausklappbar ist. Die Sichtblende 1 ist mit einer Anzeigeplatte 8 abgedeckt, die die beiden Schaltstellungen AUS, gekennzeichnet durch Bezugszeichen 0 und EIN, gekennzeichnet durch das Bezugszeichen I eines darüber angeordneten schwenkbaren Knebels 3 anzeigt. Mit dem Knebel 3 wird beispielsweise über eine Welle ein Drehantrieb eines Schaltgeräts betätigt, was aus FlG 1 jedoch nicht ersichtlich ist.In FlG 1, a lockable screen 1 is shown with a latch 2 sunk into a recess 5, which is rotatably mounted and can be folded out of the recess 5. The screen 1 is covered with an indicator plate 8, which shows the two switch positions OFF, identified by reference symbol 0, and ON, identified by reference symbol I, of a pivoting knob 3 arranged above it. The knob 3 is used, for example, to operate a rotary drive of a switching device via a shaft, which is not apparent from FlG 1.
Ist der Riegel 2 in der Mulde 5 versenkt, so ist der mit einem Hebelarm 6 versehene Knebel 3 frei zwischen den Schaltstellungen AUS/O und EIN/I schwenkbar wie auch aus den FlG 2 und 3 zu entnehmen ist. In der Schaltstellung EIN/I des Knebels 3 liegt dieser direkt über dem versenkten Riegel 2 und schaltet dessen Funktion aus.If the latch 2 is recessed in the recess 5, the toggle 3, which is provided with a lever arm 6, can be freely pivoted between the switch positions OFF/O and ON/I, as can be seen from figures 2 and 3. In the switch position ON/I of the toggle 3, it is located directly above the recessed latch 2 and switches its function off.
Der Riegel 2 ist nur in der Schaltstellung AUS/O des Knebels 3 herausklappbar und stellt sich dabei unmittelbar neben dem Hebelarm 6 auf. Dadurch versperrt der Riegel 2 die Drehung des Knebels 3 von der AUS- in die EIN-Stellung. The latch 2 can only be folded out when the knob 3 is in the OFF/O position and is positioned directly next to the lever arm 6. The latch 2 therefore blocks the rotation of the knob 3 from the OFF to the ON position.
Der Riegel 2 ist mit einer Öffnung 7 versehen. Bei aufgeklapptem Riegel 2 kann durch diese ein Vorhängeschloß A gesteckt werden, um somit die Schaltstellung AUS/O zu sichern.The latch 2 is provided with an opening 7. When the latch 2 is opened, a padlock A can be inserted through this to secure the OFF/O switch position.
