Patent
CA 2357104
An improved structure of electric lock disclosed herein employs only one electromagnetic coil and a DC power source formed of 4 3A-type dry battery unit for operating the lock instead of using two coils and an AC large power source along with a clumsy conductor layout, and a skilful arrangement of mutual positions between the driven rod and the extended portion of the actuated rod can produce an amplified driving torque effect from this minimized DC power source. Besides, the key function is controlled by a coded chip attached thereon to identify the visitor.
