Tile levelling device

Abstract

A tile levelling device of the type used on a surface to level at least two adjacent tiles which comprises:a support designed to be positioned between at least two adjacent tiles and equipped with a base designed to be positioned underneath the at least two tiles and an elongated body or rod which extends orthogonally from the base and is equipped with means for the gripping thereof from the outside;a levelling and pressure body designed to be removably connected to the support by means of the elongated body or rod and comprising a structure which is endowed with a lower edge endowed with a flat support surface intended to operate through contact with at least one of the upper surfaces of the at least two adjacent tiles; the said support surface being positioned perpendicular to the central axis of the pressure body, wherein the pressure body may be coaxially coupled by means of a magnetic attraction coupling to an external rotating member, whose task is to generate, on command, the rotation thereof in both directions. The external rotating member is, in turn, equipped with a tang for coupling with the external screwing tool and comprises, integrally coupled therewith on at least part of the internal surface thereof, at least one insert consisting of a ring-shaped magnet.

         8 . A tile levelling device of the type used on a surface to level at least two adjacent tiles and comprising:
 a support designed to be positioned between at least two adjacent tiles and equipped with a base designed to be positioned underneath the at least two tiles; an elongated body or rod which extends orthogonally from the base and is equipped with means for the gripping thereof consisting of an external thread;   a pressure and levelling body designed to be removably connected to the said support by means of the elongated body or rod and comprising a structure which is endowed with a lower edge endowed with a flat support surface intended to operate in contact with at least one of the upper surfaces of the at least two adjacent tiles, the said support surface being positioned perpendicular to the central axis of the pressure body;   wherein the pressure body may be coaxially coupled to an external rotating member whose task is to generate, on command, the rotation thereof in both directions.   
     
     
         9 . A device according to  claim 8 , wherein the pressure body may be coaxially coupled to an external rotating member by means of a magnetic attraction coupling, the said external rotating member being equipped with a tang for coupling with an external screwing tool. 
     
     
         10 . A device according to  claim 9 , wherein the external rotating member has an axially symmetrical bell shape, shaped to accommodate—perfectly centred therewithin—at least part of the upper portion of the pressure body, and comprises, integrally coupled with at least part of the internal surface thereof, at least one insert consisting of a ring-shaped magnet. 
     
     
         11 . A device according to  claim 10 , wherein the pressure body has a cylindrical shape overall and is provided with an annular insert, which is made of a ferromagnetic material and is positioned integrally and coaxially with the side walls of the said device. 
     
     
         12 . A device according to  claim 11 , wherein the axially symmetrical bell-shaped external rotating member comprises, integrally coupled with at least part of the internal surface thereof, at least one insert consisting of a ring-shaped magnet, the magnet fulfilling the function of providing the magnetic attraction with the annular insert made of ferrous material or ferromagnetic material. 
     
     
         13 . A device according to  claim 10 , wherein the pressure body has a cylindrical shape overall and is made of a magnetic material. 
     
     
         14 . A device according to  claim 13 , wherein the axially symmetrical bell-shaped external rotating member is made of a ferromagnetic material, thereby fulfilling the function of providing the magnetic attraction with the magnetic material of which the pressure body is made and with which it is coupled, the external rotating member having an axially symmetrical bell shape, shaped to accommodate—perfectly centred therewithin—at least part of the upper portion of the pressure body, and comprising, integrally coupled with at least part of the internal surface thereof, at least one insert consisting of a magnet  8  configured in an annular shape.
