Description
Die Erfindung bezieht sich auf «ine elektromagnetisch oder thermisch oder elektromagnetisch und thermisch gesteuerte Auslösevorrichtung, insbesondere für Selbstausschalter, mit einer unter der Wirkung eines Kraftspeichers stehenden, aus einer geraden in eine Bauchform überspringenden Blattfeder. Das Wesen der Erfindung besteht darin, daß die Lagerstellen des einen Endes der Blattfeder.The invention relates to an electromagnetic or thermally or electromagnetically and thermally controlled release device, especially for self-switch, with one under the action of an energy store standing, from a straight leaf spring jumping over into a belly shape. The essence of the invention is that the Bearing points of one end of the leaf spring.
ίο und des einen Endes des Kraftspeichers in einem die Auslösung des Selbstausschalters bewirkenden Drehbügel liegen und die Blattfeder in ihrer geraden Abstützstellung durch eine Druckfeder gesichert ist. Durch die An-Ordnung gemäß der Erfindung wird erreicht,, daß. zur Auslösung der Blattfeder eine wesentlich geringere Kraft gebraucht wird als bei den bekannten Anordnungen und daß andererseits die Auslösekraft der Blattfeder eine wesentlich größere wird.ίο and one end of the lift mechanism in a rotating bracket that triggers the automatic switch and the leaf spring is secured in its straight support position by a compression spring. Through the an-order according to the invention it is achieved ,, that. to trigger the leaf spring an essential less force is needed than in the known arrangements and that on the other hand the release force of the leaf spring is much greater.
Die Erfindung ist an einem Ausführungsbeispiel in der Zeichnung erläutert. Es zeigen Fig. ι die Einrichtung im gespannten und Fig. 2 im entspannten Zustand. Es sind b eine Blattfeder mit einem Auslösehebel a, ζ eine oder mehrere Zügfedern und s ein Drehbügel. Die Blattfeder b ist mit dem einen Ende mit der Grundplatte g fest verbunden, während das andere, mit dem Auslösehebel α versehene Ende im Drehbügel s beweglich gelagert ist. Am gleichen Schenkel dieses Drehbügels s greift auch der aus Zugfedern ζ bestehende Kraftspeicher an, so daß dieser bei gestreckter und durch Stellschrauben r einerseits sowie durch eine Druckfeder d andererseits abgestützter Blattfeder b gespannt ist. Sobald durch einen ganz geringfügigen Anstoß an den Austösehebel a die labile Gleichgewichtslage der Blattfeder b gestört wird, springt die Feder b in die in Fig. 2 dargestellte Bauchform über, wobei die frei werdenden Kräfte der Zugfedern 2 in der Pfeilrichtung R auf den Drehbügel s übertragen werden, so daß mit diesem eine kräftige Auslösewirkung zustande kommt und zur Steuerung von Schaltschlössern u. dgl. benutzt werden kann.The invention is explained using an exemplary embodiment in the drawing. It shows Fig. Ι the device in the tensioned and Fig. 2 in the relaxed state. There are b a leaf spring with a release lever a, ζ one or more tension springs and s a swivel bracket. One end of the leaf spring b is firmly connected to the base plate g , while the other end, provided with the release lever α , is movably supported in the swivel bracket s. The energy storage device consisting of tension springs ζ also engages on the same leg of this swivel bracket, so that it is tensioned when the leaf spring b is extended and supported by adjusting screws r on the one hand and by a compression spring d on the other. As soon as the leaf spring is disturbed b by a very slight exception to the Austösehebel a labile equilibrium position, the spring jumps b over into the position shown in Fig. 2 abdominal shape, the released force of the tension springs 2 in the direction of arrow R of the rotary bracket transferred s so that it has a powerful triggering effect and can be used to control switch locks and the like.
Durch entgegengesetzten Druck auf den in der Auslösestellung durch einen Anschlag / begrenzten Drehbügel s wird die Einrichtung wieder betriebsfertig gespannt.By opposing pressure on the in the release position by a stop / limited swivel bracket s, the device is tensioned again ready for operation.
