Large-size toy brick

Abstract

A large-size toy brick made of a soft material, more specifically of foam, said brick ( 1, 10, 20 ) being provided, on at least one top side thereof, with at least one groove ( 22 ) for slidable reception of a connecting member ( 30 ) devised for connection with a neighboring brick ( 1, 10, 20 ) provided with a mating groove ( 22 ), the at least one groove ( 22 ) and the associated connecting member ( 30 ) being configured to provide a form-positive connection in a direction perpendicular to the surface of the assembled bricks ( 1, 10, 20 ).

We claim:  
     
         1 . A large-size toy brick made of a soft material, more specifically of foam, 
 characterized in that the brick ( 1 ,  10 ,  20 ) is provided, on at least one top side thereof, with at least one groove ( 22 ) for slidable reception of a connecting member ( 30 ) devised for connection with a neighboring brick ( 1 ,  10 ,  20 ) provided with a mating groove ( 22 ), the at least one groove ( 22 ) and the associated connecting member ( 30 ) being configured to provide a form-positive connection in a direction perpendicular to the surface of the assembled bricks ( 1 ,  10 ,  20 ).    
     
     
         2 . The large-size toy brick according to  claim 1 , 
 characterized in that two grooves ( 22 ) are arranged in such a manner that the grooves ( 22 ) intersect on at least one top side of the brick ( 1 ,  10 ,  20 ).    
     
     
         3 . The large-size toy brick according to  claim 2 , 
 characterized in that the grooves ( 22 ) intersect at an angle of 90°.    
     
     
         4 . The large-size toy brick according to  claim 1 , 
 characterized in that the connecting member ( 30 ) displays mirror-image symmetry about at least one axis.    
     
     
         5 . The large-size toy brick according to  claim 1 , 
 characterized in that the connecting member ( 30 ) has a head portion ( 30   a ) and an end portion ( 30   b ) joined together by a crosspiece ( 30   c ).    
     
     
         6 . The large-size toy brick according to  claim 5 , 
 characterized in that the head portion ( 30   a ) and the end portion ( 30   b ) are identical in configuration.    
     
     
         7 . The large-size toy brick according to  claim 1 , 
 characterized in that the connecting member ( 30 ) has a cross-section in the form of a double T profile.    
     
     
         8 . The large-size toy brick according to  claim 1 , 
 characterized in that the brick ( 1 ,  10 ,  20 ) is made of polyether foam.    
     
     
         9 . The large-size toy brick according  claim 1 , 
 characterized in that the brick ( 1 ,  10 ,  20 ) is provided with a coating such as of PUR for sealing the surface thereof.
