Patent ID: 8339225

Claim:
Electromagnetic actuating device comprising a housing and two actuator pins that are supported in the housing displaceable independently from each other between a rest position retracted into the housing and a working position extended out from the housing, the actuator pins are loaded by application of force by spring elements in an extension direction, locking pins located in the housing to keep the actuator pins in the rest position by catches and are displaceable relative to the actuator pins in a movement direction of the actuator pins the locking pins are loaded by application of force by additional spring elements in the extension direction and are displaced in a retraction direction by application of electromagnetic force for releasing the catches, the actuating device has an electromagnet allocated jointly to the locking pins with a reversible direction of the magnetic field, and end sections of the locking pins facing away from the actuator pins are provided with two-pole, magnetized permanent magnets that are oriented relative to each other with opposite polarities in the movement direction.
