<p>#CMT# #/CMT# The device includes a motor (2) cooperating with driving units (3) to actuate a closing system. The motor cooperates with the driving units through mechanical transmission units (8) for automatic disengagement, in case of stop of control of the motor operation. The disengagement allows a free displacement of the driving units with respect to the motor. #CMT# : #/CMT# An independent claim is also included for a rolling slat blind or garage door type system for closing a building. #CMT#USE : #/CMT# Used for driving a closing system e.g. rolling slat blind and sliding, sectional or foldable garage door, in a building. #CMT#ADVANTAGE : #/CMT# The motor cooperates with the driving units through mechanical transmission units for automatic disengagement, in case of stop of control of the motor operation, to allow free displacement of the driving units with respect to the motor, thus eliminating the need for manual driving mechanism for rolling the apron of the rolling slat blind. The apron is therefore rolled rapidly without any pain. The driving system is simple and inexpensive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded schematic perspective view of a driving device. 2 : Motor 3 : Driving units 8 : Mechanical transmission units 9 : Driving piece 15 : Ring.</p> |
