Production Method for Radiators

Abstract

An improved method of producing radiators, for heating plants, comprising a vertical tube ( 1 ) affording holes ( 11 ) in which bushings ( 2 ) house, the bushings ( 2 ) being provided with O-rings ( 4 ) inserted in recesses ( 21, 23 a ) afforded therein. The method comprises an expanding element provided with a internal stem ( 41 ) and an external expandable tubular element ( 42 ) exhibiting longitudinal flutes ( 421 ) which enable the external tubular element ( 42 ) to expand when the stem ( 41 ) is moved axially internally of the tubular element ( 42 ), a terminal slim tract ( 24 ) of the bushing ( 2 ) being thus enlarged and belling out to strike against walls of the holes ( 11 ). The bushing ( 2 ) is then unremovably inserted into a horizontal tube ( 3 ), a washer (R) inserted on the bushing ( 2 ) being crushed between an internal wall of the horizontal tube ( 3 ) and the bushing ( 2 ), eliminating possibility of sliding of the horizontal tube ( 3 ) away from the bushing ( 2 ), the bushing ( 2 ) and the horizontal tube ( 3 ) forming a ladder-type structure for a towel-warming type radiator.

1 . An improved method of producing radiators, for heating plants, comprising a vertical tube element ( 1 ) affording holes ( 11 ) in which bushings ( 2 ) house, the bushings ( 2 ) being provided with O-rings ( 5 ) inserted in recesses ( 21 ,  23   a ) afforded therein; the method comprising an expanding element provided with a internal stem ( 41 ) and an external expandable tubular element ( 42 ) exhibiting longitudinal flutes ( 421 ) which enable the external tubular element ( 42 ) to expand when the stem ( 41 ) is moved axially internally of the tubular element ( 42 ), a terminal slim tract ( 24 ) of the bushings ( 2 ) being thus enlarged and belling out to strike against walls of the holes ( 11 ); the bushing ( 2 ) then being unremovably inserted in a horizontal tube ( 3 ), a washer (R) inserted on the bushing ( 2 ) being crushed between an internal wall of the horizontal tube ( 3 ) and the bushing ( 2 ), eliminating possibility of sliding of the horizontal tube ( 3 ) away from the bushing ( 2 ), the bushing ( 2 ) and the horizontal tube ( 3 ) forming a ladder-type structure for a towel-warming type radiator. 
   
   
       2 . The method of  claim 1 , wherein a length of the horizontal tube ( 3 ) can widely vary, thus varying a size of the radiator without varying functional characteristics thereof. 
   
   
       3 . The method of  claim 1 , wherein a size of the horizontal tube ( 3 ), the bushing ( 2 ) and vertical tubular elements ( 1 ) can be widely varied without the functional characteristics and aesthetic characteristics thereof being changed. 
   
   
       4 . The method of  claim 1 , wherein instead of only ferrous materials being used, other materials can also be used such as aluminium or alloys thereof, or non-metallic materials such as mechanically-equivalent resins. 
   
   
       5 . The method of  claim 2 , wherein a size of the horizontal tube ( 3 ), the bushing ( 2 ) and vertical tubular elements ( 1 ) can be widely varied without the functional characteristics and aesthetic characteristics thereof being changed. 
   
   
       6 . The method of  claim 2 , wherein instead of only ferrous materials being used, other materials can also be used such as aluminium or alloys thereof, or non-metallic materials such as mechanically-equivalent resins. 
   
   
       7 . The method of  claim 3 , wherein instead of only ferrous materials being used, other materials can also be used such as aluminium or alloys thereof, or non-metallic materials such as mechanically-equivalent resins.
