Modular furniture item

Abstract

A modular furniture item having a lattice supporting structure, and a number of on-floor supporting legs projecting from the supporting structure to the floor; the supporting structure having at least a first supporting rail with a substantially X-shaped cross section, and at least one anchoring clamp which is fixed to the body of at least one of the on-floor supporting legs, and is designed to selectively enclose and clamp the first supporting rail so to clamp the on-floor supporting leg rigidly and firmly, but in easily removable manner, to the body of the first supporting rail.

1 ) A modular furniture item ( 1 ) comprising a lattice supporting structure ( 2 ), and a number of on-floor supporting legs ( 3 ) projecting from the supporting structure ( 2 ) to the floor; the modular furniture item ( 1 ) being characterized in that said supporting structure ( 2 ) comprises at least a first supporting rail ( 6 ,  8 ) with a substantially X-shaped cross section; and at least one anchoring clamp ( 7 ) which is fixed to the body of at least one of said on-floor supporting legs ( 3 ), and is designed to selectively enclose and clamp said first supporting rail ( 6 ,  8 ) so to clamp the on-floor supporting leg ( 3 ) rigidly and firmly, but in easily removable manner, to the body of said first supporting rail ( 6 ,  8 ). 
   
   
       2 ) A modular furniture item as claimed in  claim 1 , characterized in that said supporting structure ( 2 ) also comprises a second supporting rail ( 8 ) which is fixed rigidly to said first supporting rail ( 6 ); said anchoring clamp ( 7 ) also being fixed to the end of said second supporting rail ( 8 ), and selectively clamping said second supporting rail ( 8 ) rigidly and firmly, but in easily removable manner, to the body of said first supporting rail ( 6 ). 
   
   
       3 ) A modular furniture item as claimed in  claim 1 , characterized in that said first ( 6 ) and said second ( 8 ) supporting rail are both positioned substantially horizontally. 
   
   
       4 ) A modular furniture item as claimed in  claim 1 , characterized in that said first supporting rail ( 6 ,  8 ) comprises four angularly-spaced longitudinal flanges ( 9 ) forming, on said first supporting rail ( 6 ,  8 ), four longitudinal grooves ( 9   a ) with a cross section substantially in the form of an isosceles triangle or isosceles trapezium; and in that said anchoring clamp ( 7 ) comprises a central supporting body ( 10 ) shaped to engage any one of the four longitudinal grooves ( 9   a ) on said first supporting rail ( 6 ,  8 ) and at the same time rest on the inner lateral sides of the two adjacent longitudinal flanges ( 9 ) defining the longitudinal groove ( 9   a ) of said supporting rail; two lateral clamping jaws ( 11 ) fitted movably to opposite sides of the central supporting body ( 10 ) so as to face the outer lateral sides of the two longitudinal flanges ( 9 ) defining the longitudinal groove ( 9   a ) engaged by said central supporting body ( 10 ); and a jaw clamping device ( 12 ) for clamping the two lateral jaws ( 11 ) onto said central supporting body ( 10 ) and onto the outer lateral sides of the two longitudinal flanges ( 9 ) defining the longitudinal groove ( 9   a ) engaged by the central supporting body ( 10 ), and so clamp the central supporting body ( 10 ) rigidly and firmly to said first supporting rail ( 6 ,  8 ). 
   
   
       5 ) A modular furniture item as claimed in  claim 4 , characterized in that the central supporting body ( 10 ) of the anchoring clamp ( 7 ) comprises, at a first end, a coupling plate ( 10   a ) which fixes rigidly onto the end of said on-floor supporting leg ( 3 ) or of said second supporting rail ( 8 ); and, at a second end, a wedge-shaped head ( 10   b ) shaped to engage a portion of any one of the four longitudinal grooves ( 9   a ) on said first supporting rail ( 6 ,  8 ) and at the same time rest on the inner lateral sides of the two longitudinal flanges ( 9 ) defining said longitudinal groove ( 9   a ) of the first supporting rail ( 6 ,  8 ). 
   
   
       6 ) A modular furniture item as claimed in  claim 1 , characterized by comprising a supporting surface ( 4 ) fixed horizontally to said supporting structure ( 2 ). 
   
   
       7 ) A modular furniture item as claimed in  claim 1 , characterized by also comprising at least one add-on module ( 5 ) fixed firmly but in easily removable manner to said supporting structure ( 2 ). 
   
   
       8 ) A modular furniture item as claimed in  claim 6 , characterized by also comprising a number of auxiliary anchoring clamps ( 17 ) for selectively fixing said supporting surface ( 4 ) and/or said add-on module ( 5 ) rigidly and firmly, but in easily removable manner, to said first supporting rail ( 6 ,  8 ).
