Supporting structrue for a cupboard or shelf system

Abstract

The invention relates to a supporting structure for a cupboard or shelf system, having a supporting rod ( 3 ) which is arranged between two joining elements. According to the invention, said supporting rod comprises at least one tab ( 9 ) which can be pivoted about an axis ( 1 ) parallel to the longitudinal axis of the supporting rod ( 3 ).

1 . A supporting structure for a cupboard or shelf system with a supporting rod positioned between two joints, 
 wherein    the supporting rod ( 3 ) includes at least one pivotable tab ( 9 ) positioned parallel to the longitudinal axis of the supporting rod ( 3 ).    
   
   
       2 . The supporting structure as recited in  claim 1 , 
 wherein    a hinge ( 8 ) with the tab ( 9 ) connects two supporting rod sections ( 2 ,  7 ) of the supporting rod ( 3 ).    
   
   
       3 . The supporting structure as recited in  claim 1 , 
 wherein    the hinge ( 8 ) has an axial, central threaded hole ( 25 ).    
   
   
       4 . The supporting structure as recited in  claim 1 , 
 wherein    the hinge ( 8 ) has a central body ( 15 ) on which a pivotable sleeve ( 14 ) is mounted, to which the tab ( 9 ) is connected.    
   
   
       5 . The supporting structure as recited in  claim 1 , 
 wherein    the sleeve ( 14 ) is inserted axially flush into a groove ( 16 ) in the central body ( 15 ).    
   
   
       6 . The supporting structure as recited in  claim 1 , 
 wherein    the sleeve ( 14 ) is inserted radially flush into a groove ( 16 ) in the central body ( 15 ).    
   
   
       7 . The supporting structure as recited in  claim 1 , 
 wherein    the geometry of the outer jacket of the central body ( 15 ) with the inserted sleeve ( 14 ) corresponds to that of the supporting rod or the supporting rod sections ( 2 ,  7 ).    
   
   
       8 . The supporting structure as recited in  claim 1 , 
 wherein    the tab ( 9 ) is displaced on the sleeve ( 14 ) relative to the axis ( 10 ) by a distance corresponding to the thickness of a door or shutter ( 11 ).    
   
   
       9 . The supporting structure as recited in  claim 1 , 
 wherein,    the central body ( 15 ) tapers at both ends in the axial direction in the shape of a truncated cone.    
   
   
       10 . The supporting structure as recited in  claim 1 , 
 wherein    the central body ( 15 ) has a two-component configuration, a first subpiece ( 17 ) including an axially extending, central inner thread ( 19 ), and a second subpiece ( 18 ) engaging with a plug-like, externally threaded projection ( 20 ) in the central inner thread ( 19 ) of the first subpiece ( 17 ).    
   
   
       11 . The supporting structure as recited in  claim 1 , 
 wherein    the supporting rod sections ( 2 ,  7 ) are formed by hollow profiles, and the hinge ( 8 ) is connected therewith via two dowel rods ( 21 ,  22 ) inserted in the supporting rod sections ( 2 ,  7 ).    
   
   
       12 . The supporting structure as recited in  claim 1 , 
 wherein    the joint ( 1 ) is attached to a supporting rod section ( 2 ) via a dowel rod ( 23 ).    
   
   
       13 . The supporting structure as recited in  claim 1 , 
 wherein    the outer dimensions of the central body ( 15 ) and the sleeve ( 14 ) of the hinge ( 8 ) correspond to those of a joint ( 1 ).    
   
   
       14 . The supporting structure as recited in  claim 1 , 
 wherein,    at both ends, the joint ( 1 ) tapers in the shape of a truncated cone in the axial direction, and a cylindrical section has a slid-on sleeve ( 32 ).    
   
   
       15 . The supporting structure as recited in  claim 1 , 
 wherein    a shaped part ( 35 ) that creates a form-fit transition is located between the joint ( 1 ) and the supporting rod ( 2 ).    
   
   
       16 . The supporting structure as recited in  claim 1 , 
 wherein    the dowel rod ( 21 ) includes two segments ( 28 ,  29 ), which are movable relative to each other, have a rectangular cross-section, and have matching wedge-shaped surfaces, the segments ( 28 ,  29 ) being clamped together via a screw ( 26 ).
