Support for raised floors with adjustable height and a swing system

Abstract

The invention is a new support for raised floors with adjustable height, comprising a cylindrical base element, threaded on the inside, for resting on the laying surface, an intermediate element or extension, threaded at top and bottom, and a top element with a concave top housing a swinging cap with diaphragms, on which the flat elements of the raised floor rest. This new support makes it possible to construct perfectly flat and continuous raised floors even in presence of considerable differences in level or slopes of the laying surface.

I claim:  
     
         1 . Support for raised floors with adjustable height, comprising a threaded cylindrical base element (B) for laying on the floor bottom and a threaded cylindrical top element (S), characterised in that said top element (S) has concave top end (Sc) housing a cap (C) on which the flat elements (E) of the raised floor are laid, said cap (C) having a corresponding curved bottom surface (CO so as to be housed, rotate and swing exactly on said concave end (Sc) of the top element (S).  
     
     
         2 . Support for raised floors with adjustable height according to  claim 1 , characterised in that the top surface (Ca) of the cap (C) is flat.  
     
     
         3 . Support for raised floors with adjustable height according to claims  1 ,  2 , characterised in that the top surface (Ca) of the cap (C) presents several vertical diaphragms (Cs) at right angles to one another.  
     
     
         4 . Support for raised floors with adjustable height according to claims  1 ,  2 ,  3 , characterised in that it comprises a threaded spacing element (S) suitable for being inserted between said base element (B) and said top element (S).  
     
     
         5 . Support for raised floors with adjustable height according to claims  1 ,  2 ,  3 , characterised in that the internal or external surface of the spacing element (S) is threaded at the bottom (Dfi) so that it can be screwed into said base element (B), and wherein the internal or external surface is threaded at the top so that it can be screwed into said top element (S).  
     
     
         6 . Support for raised floors with adjustable height according to claims  1 ,  2 ,  3 ,  4  or  5 , characterised in that the top element (S) has, in the centre of its concave top end (Sc), a linear slot (Sci) such as to contain the end of a tool and to allow the screwing and unscrewing of said top element (S).  
     
     
         7 . Support for raised floors with adjustable height according to  claim 1 ,  2 ,  3 ,  4   5 , or  6 , characterised in that the cap (C) presents in the centre a corresponding vertical hole (Cf) such as to allow a tool to pass through until reaching said slot in the top element.
