System for fastening slats

Abstract

A system for fastening to a flat surface slats having a rectangular or square plan shape predisposed to be arranged two by two side by side and spaced mutually apart to make a flooring, wall, or ceiling includes: a base integrally associated with a flat surface and configured for positioning above and/or laterally thereto at least two slats in a laying condition. The system includes a constraining component of this base to two of these slats positioned above and/or laterally thereto in the laying condition, and a supporting component of at least one of two of these slats positioned above and/or laterally to the base in the laying condition. The supporting component includes at least one bridge structure defined by two legs, connected by a crosspiece which defines, on the opposite side to the base, an abutment surface, to prevent or limit deformation of this portion towards the base.

         6 . The system according to  claim 1 , wherein said constraining means comprise a rotatable body positioned or positionable, when two of said slats are positioned above and/or laterally to said base in said laying condition, at least partially in the interspace between said slats, said rotatable body being rotatable with respect to said base between a retaining position, in which said rotatable body is constrained to said base and to two of said slats when said slats are positioned above and/or laterally to said base in said laying condition, and a release position in which, when two of said slats are positioned above and/or laterally to said base in said laying condition, said rotatable body is not constrained to said two slats, allowing the separation from said rotatable body and from said base, wherein said rotatable body comprises means for constraining the mutual rotation between said rotatable body and one end of a tool configured to be inserted with said end in the interspace between two of said slats positioned above and/or laterally to said base in said laying condition. 
     
     
         7 . The system according to  claim 6 , further comprising end stop means adapted to delimit the rotation of said rotatable body with respect to said base between said retaining position and said release position. 
     
     
         8 . The system according to  claim 6 , wherein said means for constraining the mutual rotation between said rotatable body and one end of a tool comprise a groove formed in said rotatable body ( 6 ), adapted to insert said end of said tool and shaped in such a way that said end cannot rotate in said groove once said end is inserted therein, so that a rotation of said end of said tool involves the integral rotation of said rotatable body. 
     
     
         9 . The system according to  claim 6 , wherein said rotatable body is formed in one piece with said base, and is rotatable with respect to the same after breaking or deformation of connecting means between said base and said rotatable body, formed in one piece therewith. 
     
     
         10 . The system, according to  claim 9 , wherein said rotatable body is formed in one piece with said base in said release position, and is rotatable in said retaining position after breaking or deformation of said connecting means.
