Abstract (en)
[origin: US5924750A] A door opener wich can be used for closed-circuit current operation as well as for working current operation, includes a door latch and a trimmer which can be moved for blocking and releasing the door latch, an armature which can be displaced for blocking or releasing the trimmer, an electromagnet for displacing the armature, whereby the armature can be moved between three consecutive armature positions, namely a first armature position, a second armature position, and a third armature position. The armature positions alternately provide a locking and releasing of the door latch. The door opener also includes a stop element, which can be displaced for delimiting the displacement path of the armature between a first stop position and a second stop position such that the first or third armature position is blocked.
