Wall element

Abstract

In a wall element ( 1, 2 ) for a mobile dividing wall with a wall member ( 3 ) and a border profile ( 4 ), the said profile comprises a base member (G), which is firmly joined to the wall member ( 3 ), and a revolving element ( 10, 10′ ) mounted therein to turn around its axis ( 15 ). The base member (G) comprises two lips ( 18 ) bearing substantially against the revolving element ( 10, 10′ ). The revolving element ( 10, 10′ ) is coated on part of its surface with burr material ( 16 ) and is otherwise provided with at least one further surface structure. Depending on the angular position of the revolving element, the burr material ( 16 ) or alternatively the different surface structure or one of the different surface structures is exposed externally between the two lips ( 18 ).

         7 . A wall element according to one of  claims 1  to  6 , characterized in that 
 the revolving element ( 10 ′) has a cloth covering ( 23 ) on part of its surface.  
 
     
     
         8 . A wall element according to one of  claims 1  to  7 , characterized in that 
 the revolving element ( 10 ′) has a powdered or anodized aluminum coating ( 24 ) on part of its surface.  
 
     
     
         9 . A wall element according to one of  claims 1  to  8 , characterized in that 
 the revolving element ( 10 ′) has on its surface axial grooves ( 22 ) which define the different surface regions.  
 
     
     
         10 . A wall element according to one of  claims 1  to  9 , characterized in that 
 the angular position of the revolving element ( 10 ,  10 ′) in the base member (G) can be fixed by means of an immobilizing device.  
 
     
     
         11 . A wall element according to  claim 10 , characterized in that 
 the immobilizing device is designed as a clamping device.
