#CMT# #/CMT# The device has a dynamo coil (4) electrically connected to a rechargeable battery, and a spring loaded pulley (14) mechanically connected to the coil. A string (10) is wrapped around the pulley and includes a pulling ring (9) at its distal end. The string extends from the device for its alternative retraction and traction outside and on the pulley for activating the coil for charging the battery. A gear (8) is mounted with respect to the pulley in a coaxial manner, where the coil and the pulley are configured co-axially so that the gear has inwardly facing teeth. #CMT#USE : #/CMT# Portable electric device e.g. portable radio and torch. #CMT#ADVANTAGE : #/CMT# The dynamo coil and the pulley are configured co-axially so that the gear has inwardly facing teeth, thus providing a compact electric device having a dynamic battery recharging capacity. The device permits to recharge the battery in an appropriate manner without utilizing a transformer or a group of external supply circuits. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic vertical sectional view of a portable electric device. 4 : Dynamo coil 5 : Support frame 8 : Gear 9 : Pulling ring 10 : String 14 : Spring loaded pulley 16 : Chassis.
