Electrically switchable locking device for a window or a door as well as the use of a piezoelectric actuator and / or a magnetostrictive actuator and / or of a shape - memory - actuator

摘要

there will be a door opener is described. it is with the schlou00dffalle 51 zusammenwirkende tu00fcru00f6ffnerfalle 61. this is tu00fcru00f6ffnern on conventional magnets or electric motor actuated. $a simpler structure and very compact size to receive is provided that the operation of the tu00fcru00f6ffnerfalle 61 a piezoaktor 7 is used.instead of the piezoaktors 7 can also be a magnetostriktiver actuator or a shape memory actuator is used.
