Abstract

Die Erfindung betrifft eine bistabile Magnetverriegelung, bestehend aus einem verschiebbaren Magnetanker (5), der kopfseitig einen Teil einer mechanischen Verriegelung bildet und der von wenigstens einer elektrisch erregbaren Magnetspule (2,3) umgeben ist, die die Verschiebung bewirkt, und zwar in eine ausgefahrene Endposition (Verriegelungsposition) und in eine zurückgezogene Endposition (Freigabeposition).The invention relates to a bistable magnetic lock consisting of a Slidable magnetic armature (5), the part of a mechanical locking head forms and which is surrounded by at least one electrically excitable magnetic coil (2, 3), which causes the displacement, namely in an extended end position (Locking position) and in a retracted end position (release position).

Dabei sind mit dem Magnetanker (5) federbelastete Arretierungen (8) radial in Eingriff bringbar, die den Magnetanker mechanisch in der jeweiligen Endposition halten.
