Description

Elektromagnetisches Signalhorn, insbesondere für Kraftfahrzeuge Gegenstand der Hauptpatentanmeldung W 24427 VIIId/74d ist ein elektromagnetisches Signalhorn, insbesondere für Kraftfahrzeuge, dessen langgestreckter, zentral an einer Membran befestigter Anker lediglich den Mittelpol eines periodisch erregten dreipoligen Magneten beaufschlagt. Das Signalhorn ist dadurch gekennzeichnet, daß der Anker in der Längsrichtung leicht durchgebogen ist, derart, daß seine beiden freien Enden im Winkel zu den mit den Mittelpolen in einer Ebene liegenden Außenpolflächen verlaufen. Dabei ist der Anker beidends über den Bereich der Außenpole hinaus verlängert. Außerdem weist gemäß Anspruch 3 der Hauptpatentanmeldung der Anker beiderseits seiner zentralen Befestigungsstelle nuerschnittsverringerungen auf, die an sich bekannt sind.Electromagnetic horn, in particular object for motor vehicles the main patent application W 24427 VIIId / 74d is an electromagnetic signal horn, especially for motor vehicles, whose elongated, centrally on a membrane attached anchor only the center pole of a periodically excited three-pole Magnet applied. The horn is characterized in that the anchor is slightly bent in the longitudinal direction, such that its two free ends run at an angle to the outer pole faces lying in one plane with the central poles. The armature is extended beyond the area of the outer poles at both ends. aside from that has according to claim 3 of the main patent application, the anchor on both sides of its central Fastening point on nuerschnittsverrederungen, which are known per se.

Sie sind z. B. in Form von sich unmittelbar an die Befestigungsstelle anschließenden Quernuten oder von Ausnehmungen aus dem Ankerwerkstoff, die sich vom Ankerrand in Richtung auf die Ankermitte erstrecken, bekanntgeworden.You are e.g. B. in the form of itself directly to the attachment point subsequent transverse grooves or recesses from the anchor material, which are extend from the edge of the anchor towards the center of the anchor, became known.

Es wurde nun gefunden, daß es vorteilhaft ist, diese Querschnittsverringerungen in Form von Ausnehmungen in den Bereich der Wicklungsnuten des Elektromagneten zu legen. Hierdurch wird ein ungestörter Kraftfluß sichergestellt.It has now been found that it is advantageous to reduce these cross-sectional areas in the form of recesses in the area of the winding grooves of the electromagnet place. This ensures an undisturbed flow of force.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung, und zwar stellt Fig. 1 einen Schnitt durch die elektrische Einrichtung des elektromagnetischen Signalhorns dar, während Fig. 2 die Draufsicht auf den Anker zeigt.The drawing illustrates an embodiment of the invention, namely Fig. 1 shows a section through the electrical device of the electromagnetic Signal horn, while Fig. 2 shows the top view of the anchor.

Der Anker 1, der lediglich den Mittelpol 5 des dreipoligen Magneten 3 beaufschlagt, während die Seitenpole 4 aus dem Aufschlagbereich der freien Enden 6 des Ankers herausgenommen sind, weist beiderseits der Aufschlagstelle Ausnehmungen 7 auf, die erfindungsgemäß im Bereich der Wicklungsnuten 8 des Elektromagneten liegen.The armature 1, which only has the center pole 5 of the three-pole magnet 3 acted upon, while the side poles 4 from the impact area of the free ends 6 of the anchor are removed, has recesses on both sides of the point of impact 7, which, according to the invention, lie in the region of the winding slots 8 of the electromagnet.
