Description
Kontaktvorrichtung, insbesondere für elektrische Uhren Die Erfindung betrifft eine Kontaktvorrichtung für beliebige Anwendungszwecke, insbesondere aber für elektrische Uhren, ob diese letzteren für die Zeitmessung oder für andere Zwecke, wie z. B. Geschwindigkeitsmesser, Tachometer o. dgl., benutzt werden mögen. Die Erfindung verwendet in bekannter Weise für den einen Kontakt biegsame Körper und für den anderen uninachgiebige, zeichnet sich aber dadurch aus, daß als biegsamer Körper eine an beiden Enden festliegende Schraubenfeder verwendet wird, die als unmittelbarer Kontakt dient. Bei der Verwendung der bekannten biegsamen Kontakte, z. B. in Gestalt von Lamellen, ist man genötigt, die beeiden Enden derselben in. besonderen Lagern zu führen, wobei Klemmungen stattfinden können. Die Schraubenfeder gemäß Erfindung dagegen besitzt nicht nur den Vorteil einer größeren Biegsamkeit, sondern noch den Vorteil, daß sie sich unter dem Druck des anderen Kontaktes verlängert und dann beim Nachgeben des Druckes selbsttätig verkürzt, wodurch es möglich wird, ihre beiden Enden fest anzubringen. Ein weiterer Vorteil der Anwendung von Schraub-enfedexn besteht in der größeren Anzahl von Berührungspunkten zwischen den beiden Kontakten und außerdem in einer mehr oder weniger großen Verschiebung der Berührungspunkte während des Biegens und Zurückbiegens selbst, so daß die Kontakte durch die dabei auftretende Reibung reingehalten werden.Contact device, in particular for electrical clocks. The invention relates to a contact device for any application, but in particular for electrical clocks, whether the latter for timekeeping or for other purposes, such as B. speedometer, tachometer or the like. May be used. the Invention used in a known manner for the one contact flexible body and for the other unyielding, but is characterized by the fact that as more flexible Body a coil spring fixed at both ends is used, which as serves direct contact. When using the known flexible contacts, z. B. in the form of lamellas, one is forced to put the two ends of the same in. to lead special bearings, whereby jamming can take place. The coil spring according to the invention, however, not only has the advantage of greater flexibility, but also the advantage that it elongates under the pressure of the other contact and then automatically shortened when the pressure gives way, which makes it possible to attach both ends firmly. Another advantage of using screw enfedexn consists in the greater number of points of contact between the two contacts and also in a more or less large displacement of the points of contact during the bending and bending back itself, so that the contacts through the doing occurring friction are kept clean.
Die Zeichnung veranschaulicht eine Ausführungsform des Erfindungsgegenstandes in der Arbeitslage.The drawing illustrates an embodiment of the subject matter of the invention in the work situation.
Der eine, mit i bezeichnete Kontakt besitzt in Aufsicht die Gestalt einer Kurve von großem Krümmungshalbmesser und ist in nicht dargestellter Weise derart angeordnet, daß er Hinundherbewegungen gegen den anderen Kontakt ausführen kann. Der Kontakt i besteht aus einem unnachgiebigen metallischen Stoff.The one contact marked i has the shape when viewed from above a curve of large radius of curvature and is in a manner not shown arranged so that it reciprocates against the other contact can. The contact i consists of an unyielding metallic material.
Der andere Kontakt ist als Schraubenfeder 3 ausgebildet, die mit ihren beiden Enden q. an den Armen z befestigt ist.The other contact is designed as a coil spring 3 with their both ends q. is attached to the arms z.
