Multiple retaining wall block unit with off-center splitting grooves

Abstract

Disclosed is a multiple retaining wall block unit provided with at least one set of splitting grooves positioned in such a manner as to permit splitting and separation of the blocks from the unit. The invention lies in that the set of splitting grooves is located along the unit in such a manner that the adjacent blocks that can be splitted, are not of a same length. As a result, the blocks when stacked on top of each other, have their front faces that do not extend necessarily in the same place, thereby giving more originality to the look of the retaining wall.

1 . In a multiple retaining wall block unit provided with at least one set of splitting grooves positioned in such a manner as to permit splitting and separation of said blocks from said unit, the improvement wherein said at least one set of splitting grooves is located along said unit in such a manner that the adjacent blocks that can be splitted, are not of a same length.  
   
   
       2 . The improved unit of  claim 1 , wherein each of the blocks of said unit has an upper surface provided with at least one upwardly projecting tongue and a bottom surface with at least one groove sized to receive the tongue of a similar block extending below when said retaining wall is built up.  
   
   
       3 . The improved unit of  claim 2 , wherein: 
 said unit comprises only two blocks having front surfaces facing each other in a same vertical plane;    the set of splitting grooves permitting splitting of said two blocks is positioned in said vertical plane; and    said vertical plane is off-center with respect to said unit.
