Mobile ring connecting/release device, in particular for a high mast

Abstract

A mobile ring ( 1 ) connecting/release device ( 8 ), in particular for a high mast with a tower with predetermined height and a fixed supporting head ( 3 ) at one end of the tower. The device ( 8 ) comprises connecting means attached to the mobile ring ( 1 ) for removably connecting it to the fixed supporting head ( 3 ). In an original way, these means have rigid contact elements ( 9 ) shaped in such a way that they rest on corresponding supporting head ( 3 ) contact portions ( 10 ).

1 . A mobile ring ( 1 ) connecting/release device ( 8 ), in particular for a high mast with a tower with predetermined height and a fixed supporting head ( 3 ) at one end of the tower, comprising connecting means attached to the mobile ring ( 1 ) in such a way as to removably connect it to the fixed supporting head ( 3 ), the connecting/release device being characterised in that the connecting means comprise rigid contact elements ( 9 ) shaped in such a way that they rest on corresponding supporting head ( 3 ) contact portions ( 10 ).  
   
   
       2 . The device according to  claim 1 , characterised in that each contact element ( 9 ) is rotatably fixed on a corresponding mobile ring ( 1 ) upright ( 11 ).  
   
   
       3 . The device according to  claim 2 , characterised in that each of the contact elements ( 9 ) is shaped in such a way that it is at an angle to a horizontal direction, in the home configuration.  
   
   
       4 . The device according to  claim 2 , characterised in that the contact portions ( 10 ) form guides for insertion of the mobile ring ( 1 ) upright ( 11 ) in the fixed supporting head ( 3 ).  
   
   
       5 . The device according to  claim 4 , characterised in that the fixed supporting head ( 3 ) comprises means for activating a rotation of a contact element ( 9 ) about an axis substantially perpendicular to a mobile ring ( 1 ) upright ( 11 ), for aligning the contact element ( 9 ) with the upright ( 11 ) and allowing insertion of the latter in the guides ( 10 ).  
   
   
       6 . The device according to  claim 5 , characterised in that the means for activating the rotation comprise at least one pusher body ( 13 ) connected to the guides ( 10 ) and/or at least one peg ( 14 ) fixed to the supporting head ( 3 ), both acting on a portion ( 9   a ) of a contact element ( 9 .).  
   
   
       7 . The device according to  claim 2 , characterised in that each contact element ( 9 ) is fixed on a corresponding mobile ring ( 1 ) upright ( 11 ) by means of a single pin ( 12 ).  
   
   
       8 . The device according to  claim 1 , characterised in that the contact portions ( 10 ) have at least one substantially horizontal and flat surface ( 10   a ).  
   
   
       9 . The device according to  claim 8 , characterised in that the contact elements ( 9 ) have at least one substantially flat outer surface ( 9   a ;  91   a ), allowing them to rest without gaps on the corresponding flat surface ( 10   a ) of the contact portions ( 10 ).
