#CMT# #/CMT# The electromagnet has a movable armature (12) to carry out successive or simultaneous movements of rotation and translation under the effect of magnetic field generated by an electric current pulse in a coil (14). The movable armature has a piece (20) and levers (24, 26) that are rotated around an axis and are pivotably mounted on a frame. A U-shaped fixed armature (10) has a part (16) engaged in the coil, and another part (18) partially enclosing the coil. Each lever is arranged such that its center of gravity is found on its corresponding pivoting axis. #CMT# : #/CMT# An independent claim is also included for a lock comprising an electromagnet. #CMT#USE : #/CMT# Secured electromagnet for controlling a lock (claimed) of a bank note dispenser. #CMT#ADVANTAGE : #/CMT# The movable armature carries out successive or simultaneous movements of rotation and translation under the effect of magnetic field generated by the electric current pulse in the coil so as to prevent the lock from being violated by releasing a bolt under the effect of impact, thus avoiding an ill-timed opening of the lock by application of the impact, in a simple and inexpensive manner, and hence assuring safe operation of the lock. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an electromagnet. 10 : U-shaped fixed armature 12 : Movable armature 14 : Coil 16, 18 : Parts 20 : Piece 24, 26 : Levers. |
