The device is shown here in a three dimensional view at an angle to the front. It is of very simple design and essentially consists of a fan ( 1 ), with a blower pipe ( 2 ) and a holding container ( 3 ) for a hollow cylindrical cord reel placed around the blower pipe ( 2 ). This cord reel ( 4 ) can be seen here because the holding container ( 3 ) is made from a polycarbonate section of tubing, thus providing a view of its interior. The cord reel ( 4 ) consists of a cable insertion cord. Along its cylindrical axis, the cord reel ( 4 ) exhibits a free space ( 5 ), from which the cord ( 6 ) is gradually spooled radially to the outside. At the holding container's ( 3 ) front end, it is sealed to a flange ( 8 ), which carries a nozzle ( 10 ). When running, the fan conveys air through the device axially, so that the cord ( 6 ) is carried along too and thereby unwound from its reel ( 4 ) and thence through the nozzle ( 10 ) to the outside and then through a connected cable conduit of whatever length and even having many twists and turns.
