Description
Bei auf Platten zu befestigenden Klingeldruckknöpfen werden leicht Störungen elektrischer Signalanlagen dadurch hervorgerufen, daß der auf der Vorderseite der Kontaktplatte befindliche Teil des Druckknopfes sich lokkert. Gefährlich wird dies, sofern die Signalanlage mit Starkstrom arbeitet. Die vorliegende Erfindung vermeidet diesen Nachteil. In den Abbildungen ist der Erfindungsgegenstand in beispielsweiser Ausführung dargestellt. Abb. ι zeigt die Außenansicht des Druckknopfes, Abb. 2 den Querschnitt, Abb. 3 die Kontaktplatte.In the case of bell push buttons to be fastened to plates, malfunctions easily become electrical Signal systems caused by the fact that the on the front of the contact plate located part of the push button loosens. This becomes dangerous if the signal system works with heavy current. The present invention avoids this disadvantage. The subject matter of the invention is shown in an exemplary embodiment in the figures. Fig. Ι shows the external view of the push button, Fig. 2 the cross section, Fig. 3 the contact plate.

»5 taktes bestehen aus Isoliermaterial. In den meisten Fällen werden die Druckkontakte an Metallplatten (an Hauseingängen) befestigt. Da nun bei Temperaturanstieg die Ausdehnung der Metallplatte größer ist als die der Isolierteile und bei Temperaturfall die Metallplatte sich stärker zusammenzieht als die Isoüerteile, tritt eine Lockerung der gegenseitig verschraubten Teile b, α ein. Zur Verhinderung des Lockerwerdens und unbefugten Herausschraubens ist erfindungsgemäß in den an der Vorderseite der Platte befindlichen Einsatzteilb ein Arretierstifte eingesetzt, welcher nach erfolgter Montage in Aussparungen ia der Kontaktplatte eingreifen kann, wonach sich der Teil6 nicht mehr drehen läßt, also von der Vorderseite der Kontaktplatte nicht mehr gelöst werden kann. Um ein Lösen des Teiles b überhaupt zu ermöglichen, muß die Platte abmontiert und der Teil a abgeschraubt werden.»5 clocks are made of insulating material. In most cases, the pressure contacts are attached to metal plates (at house entrances). Since, when the temperature rises, the expansion of the metal plate is greater than that of the insulating parts and, when the temperature drops, the metal plate contracts more than the insulating parts, the mutually screwed parts b, α become loosened. To prevent loosening and unauthorized unscrewing, according to the invention, a locking pin is inserted into the insert part b located on the front of the plate , which after assembly can engage in recesses i a of the contact plate, after which the part 6 can no longer be rotated, i.e. from the front of the Contact plate can no longer be released. In order to enable part b to be released at all, the plate must be dismantled and part a unscrewed.
Das Loch in der Kontaktplatte kann eine oder auch mehrere Aussparungen haben, um dem Teil α eine günstige Stellung geben zu können.The hole in the contact plate can have one or more recesses in order to be able to give the part α a favorable position.
