Description

Selbsttätiger elektromagnetischer Kegelstandanzeiger Die Erfindung bezieht sich auf einen selbsttätigenelektromagnetischen Kegelstandanzeiger mit bildlicher Darstellung des Wurfergebnisses am Keglerstand. Die bisher bekannten, Kegelstandanzeiger dieser Art wirkten mittels Schaltkontakte, die durch den aufgestellten oder gefallenen Kegel beeinflußt wurden. Durch auftretende starke Erschütterungen und durch eindringenden Staub wurden solche Einrichtungen bald unbrauchbar. Dieser Nachteil tritt bei dem erfindungsgemäßen Kegelstandanzeiger nicht auf, da an Stelle empfindlicher Kontakte fest eingebaute Induktionsspulen vorgesehen sind, deren magnetischer Kraftlinienfluß durch die in dem daraufgestellten Kegel befindliche Eisenplatte geschlossen wird.Automatic electromagnetic cone level indicator The invention refers to an automatic electromagnetic taper indicator with pictorial Presentation of the throwing result at the bowling stand. The previously known, cone level indicator of this kind worked by means of switching contacts, which were set up or fallen Cones were affected. Due to strong vibrations and penetrating Dust soon made such facilities unusable. This disadvantage occurs with the The cone level indicator according to the invention does not appear, since it is in place of sensitive contacts Fixed induction coils are provided, the magnetic flux of lines of force is closed by the iron plate located in the cone on top.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigt Abb. i die Anordnung der doppelten - Induktionsspüle mit dem Magnetjoch und aufgestelltem Kegel, Abb. z in kleinerem Maßstabe die schematische Anordnung des Kegelstandanzeigers.The drawing shows an exemplary embodiment of the subject matter of the invention shown, namely Fig. i shows the arrangement of the double induction sink with the magnetic yoke and cone set up, Fig. z on a smaller scale the schematic Arrangement of the cone level indicator.

Der als Aufstellplatte ausgebildete Magnetkörper a trägt die Induktionsspulen b und, c. Eine dieser Spulen ist an Wechselstrom angeschlossen. In der anderen wird ein Strom induziert, sobald der Kegel d mit dem unten angebrachten Eisenteile auf das Magnetjoch a gestellt wird; dadurch wird der für die Induktion erforderliche magnetische Kreis geschlossen. Der induzierte Strom zur Anzeigetafel g am Keglerstand oder zum Anschreiber geleitet, zeigt dort, etwa durch Lampen, selbsttätig an, ob der Kegel steht, ob er richtig aufgestellt ist oder ob er' gefallen ist. Sind die Lampen der Anzeigetafel dem Kegelstand f entsprechend angeordnet, so erscheint auf der Anzeigetafel :ein genaues Abbild des Wurfergebnisses.The magnetic body a designed as a mounting plate carries the induction coils b and c. One of these coils is connected to alternating current. In the other, a current is induced as soon as the cone d with the iron part e attached below is placed on the magnet yoke a; this closes the magnetic circuit required for induction. The induced current passed to the scoreboard g at the bowling stand or to the marker, there, for example by means of lamps, automatically indicates whether the cone is standing, whether it is correctly positioned or whether it has fallen. If the lamps on the scoreboard are arranged according to the pin position f, the scoreboard shows: an exact image of the throwing result.
