Description
Bei der Verwendung von Klinkenauslösungen für größere Schalter, bei denen sich zwischen dem Antrieb und dem eigentlichen Schalter Übertragungsglieder, Stangen o. dgl. befinden, tritt die Schwierigkeit auf, daß durch die toten Gänge die Druckwirkungen auf die Klinkenteile unverhältnismäßig hoch werden, so daß häufig darunter das sichere Abschalten leidet. Diese Schwierigkeit wird ίο bei der vorliegenden Anordnung dadurch behoben, daß an der Achse der zu bewegenden Schalterteile oder eines mit der Achse verbundenen Zwischengliedes mehrere Kugelklinken auf dem Umfang eines Kreises so angreifen, daß sich der Druck der Sperrglieder auf das mit den Schalterteilen verbundene, zentral gelegene Glied möglichst aufhebt und sich letzteres im Druckmittelpunkt selbsttätig einstellen kann. Diese Lösung ergibt die Möglichkeit, die sonst vorhandenen toten Gänge unschädlich zu machen, wobei ferner der Kraftbedarf an der Verklinkung auf ein Mindestmaß zurückgeht und somit die Sicherheit der Auslösung wesent-Hch erhöht wird. Für die Ausführung dieser Anordnung ist es dabei gleichgültig, ob man für das Halten des zu bewegenden Teiles Kugeln, Walzen oder an den Endein kugelförmig oder walzenförmig ausgebildete Riegel verwendet. Auch kann das abzulösende bewegliche Glied direkt oder indirekt mit dem so gebildeten Auslöseschloß in Verbindung stehen.When using jack releases for larger switches where between the drive and the actual switch transmission elements, rods or the like. are located, the difficulty arises that the pressure effects through the dead passages on the latch parts are disproportionately high, so that often including the safe Switching off suffers. This difficulty is ίο remedied in the present arrangement by that on the axis of the switch parts to be moved or one connected to the axis Intermediate member attack several ball pawls on the circumference of a circle so that the pressure of the locking members on the centrally located link connected to the switch parts as possible and the latter is in the center of pressure can adjust automatically. This solution creates the possibility of the otherwise existing to render dead corridors harmless, and also the power requirement at the latch goes back to a minimum and thus the security of the release is essential is increased. For the execution of this arrangement it does not matter whether one for holding the part to be moved balls, rollers or spherical at the ends or roller-shaped bars are used. The movable member to be detached can also be direct or indirect are in connection with the release lock formed in this way.
Die Abbildungen geben eine der möglichen Ausführungsformen wieder, und zwar zeigt Abb. ι den Schalter eingeschaltet, Abb. 2 den Schalter in der AusschaltsteJlung. a undo sind die beiden in Eingriff kommenden Schaltglieder. In dem kreisförmigen Schaltglied b, das durch Drehung in die verklinkte Lage gebracht werden kann, sind kreuzweise Kerbungen eingearbeitet, die zur Aufnahme von Kugeln c dienen. Die Enden dieser so gebildeten Kugelreihen stoßen einerseits gegen einen beweglichen Druckstift d an, andererseits legen sie sich in der Einschaltstellung in Auskerbungen e des Schaltgliedes a. Hierdurch sind die Schaltglieder a und b fest gekuppelt. Durch Verschieben des Druckstiftes d können sich die Kugeln in Richtung der Drehachse bewegen, die Verklinkung zwischen den Schaltgliedern α und b wird aufgehoben und so eine augenblickliche Abschaltung bei geringster Druckentfaltung herbeigeführt.The figures show one of the possible embodiments, namely Fig. 1 shows the switch switched on, Fig. 2 the switch in the off position. a undo are the two engaging switching elements. In the circular switching element b, which can be brought into the latched position by rotation, notches are worked crosswise, which serve to accommodate balls c. The ends of these rows of balls formed in this way, on the one hand, abut against a movable pressure pin d , on the other hand, in the switched-on position, they lie in notches e of the switching element a. As a result, the switching elements a and b are firmly coupled. By moving the pressure pin d , the balls can move in the direction of the axis of rotation, the latching between the switching elements α and b is canceled and an instantaneous shutdown is brought about with the slightest pressure development.
