Appliance for introducing flex into a cable sheath for the subsequent introduction of an electric cable

Abstract

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.

1 - 10 . (canceled)  
   
   
       11 . An apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable, comprising: 
 a housing having a handle with a pistol-like grip and a push, toggle or rocker switch;    a hollow cylindrical holding container for taking a cord reel to be unwinded, said housing being at a backside of said hollow cylindrical holding container;    an outlet nozzle for an outlet of cord at a front side of said hollow cylindrical holding container;    a blower pipe extending axially through said hollow cylindrical holding container and projecting into said outlet nozzle, so that a cylindrical cord reel having a cylindrical outer side, and for unwinding from inside, fits with its outer diameter into said hollow cylindrical holding container and with a central free space over said blower pipe, wherein said blower pipe completely crosses an inserted cord reel and remains spaced from the cylindrical cord reel around itself; and,    an electrical fan within said housing for producing an air current capable of passing from the backside of said hollow cylindrical holding container through said blower pipe, or on its outer side along said blower pipe, and through said outlet nozzle on the front side of said hollow cylindrical holding container to an outside area, so that said air current continually unwinds cord from an inner side of said cord reel and takes the cord through said outlet nozzle.    
   
   
       12 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 11 , wherein said blower pipe extends axially through said hollow cylindrical holding container and through said central free space of the inserted cord reel and ends in an inner side of said outlet nozzle.  
   
   
       13 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 12 , wherein said hollow cylindrical holding container is attached to a flat side of said housing containing said electrical fan and comprises a pipe section having a flange at one end, with said blower pipe crossing said pipe section and protruding therefrom and with said flange being attached onto said flange via a central hole, bearing a spaced retaining ring on its inner side for sup-porting the inserted cord reel and, on its outside, said outlet nozzle for the cord.  
   
   
       14 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 12 , wherein said outlet nozzle is sealed into a socket, which is fitted to a flange, with said outlet nozzle having a circular groove on an outer side for permitting radially interspersed bolts are engagable in said socket.  
   
   
       15 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 12 , wherein said pistol-like grip of said handle of said housing is operable via a user's index finger of a hand enclosing said pistol-like grip.  
   
   
       16 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 12 , wherein said housing is made from a plastic tubing and said handle is made from a wire loop with two angled loops pointing downwardly, so that said wire loop creates two grip handles opposite one another.  
   
   
       17 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 12 , wherein said electrical fan has a rear side closed by an annular bezel with a central hole and with an air intake socket placed around the central hole, which is internally equipped with a mesh grid.  
   
   
       18 . The apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable according to  claim 12 , further comprising a vacuum cleaner motor for driving said electrical fan, said vacuum cleaner motor having an electrical output of 700 to 1,400 watts.  
   
   
       19 . An apparatus for inserting a cord into a cable conduit for subsequently pulling through an electrical cable, comprising: 
 a housing having a handle with a pistol-like grip and a push, toggle or rocker switch;    a hollow cylindrical holding container for taking a cord reel to be unwinded, said housing being at a backside of said hollow cylindrical holding container;    an outlet nozzle for an outlet of cord at a front side of said hollow cylindrical holding container;    a rod extending axially through said hollow cylindrical holding container and projecting into said outlet nozzle, so that a cylindrical cord reel having a cylindrical outer side, and for unwinding from inside, fits with its outer diameter into said hollow cylindrical holding container and with a central free space over said rod, wherein said rod completely crosses an inserted cord reel and remains spaced from the cylindrical cord reel around itself; and,    an electrical fan within said housing for producing an air current capable of passing from the backside of said hollow cylindrical holding container through said rod and through said outlet nozzle on the front side of said hollow cylindrical holding container to an outside area, so that said air current continually unwinds cord from an inner side of said cord reel and takes the cord through said outlet nozzle.
