Precast concrete stone with angled side wall section

Abstract

A precast concrete stone is provided with an angled side wall section and has a base section of predetermined thickness and straight side wall sections, one of which is an angled side wall section. A stone section is formed integral with the base section and projects from an outer surface of the base section. The stone section is recessed from at least two adjacent ones of the straight side wall sections and exposes a top flat edge surface of the outer surface of the base section about at least two adjacent flat edge surfaces of the stone section. The side wall section is adapted to mate with an angled side wall section of another precast concrete stone whereby stone can be disposed side-by-side and offset from one another to obstruct a straight continuous joint between a plurality of adjacent stones.

1 . A precast concrete stone comprising a base section of predetermined thickness and having straight side wall sections, a stone section formed integral with said base section and projecting from an outer surface of said base section, said stone section being recessed from at least two adjacent ones of said straight side wall sections and exposing a top flat edge surface of said outer surface of said base section about at least two adjacent flat edge surfaces of said stone section, at least one of said straight side wall sections being an angled side wall section adapted to mate with an angled side wall section of another precast concrete stone whereby said stones can be disposed side-by-side and offset from one another to obstruct at least some straight continuous joints between a plurality of adjacent stones.  
   
   
       2 . A precast concrete stone as claimed in  claim 1  wherein said stone section is recessed from all of said straight side walls exposing said flat edge surface all about said stone section.  
   
   
       3 . A precast concrete stone as claimed in  claim 2  wherein said stone section has an irregular contour side wall.  
   
   
       4 . A precast concrete stone as claimed in  claim 3  wherein said stone section has an irregular top surface resembling a stone texture.  
   
   
       5 . A precast concrete stone as claimed in  claim 2  wherein said base section is at least twice the thickness of said stone section.  
   
   
       6 . A precast concrete stone as claimed in  claim 2  wherein said stones, when positioned side-by-side, define a recessed joint therebetween formed by adjacent top flat edge surfaces of said base sections of said stones.  
   
   
       7 . A precast concrete stone as claimed in  claim 2  wherein said precast concrete stone is a paver stone.  
   
   
       8 . A precast concrete stone as claimed in  claim 4  wherein said stone section has rounded corners and wherein said top surface is a molded embossed top surface.  
   
   
       9 . A precast concrete stone as claimed in  claim 2  wherein said precast concrete stone is a retaining wall block wherein said side wall sections are elongated side wall sections forming a retaining wall block section adapted to be laid horizontally in side wall contact with like adjacent blocks with said stone section being disposed vertically.  
   
   
       10 . A precast concrete stone as claimed in  claim 9  wherein said retaining wall block sections provided with opposed aligned transverse grooves in opposed horizontal side walls thereof and adapted to receive an interlocking insert therein for interlocking blocks in aligned facial contact.  
   
   
       11 . A ground surface covering comprising at least two precast concrete stones as claimed in  claim 1  in combination with a plurality of rectangular precast concrete stones having a base section of predetermined thickness and opposed straight parallel sidewall sections, a substantially rectangular stone section formed integral with said base section and projecting from an outer surface of said base section, said stone section being recessed from said straight parallel sidewall sections and exposing a top flat edge surface of said outer surface of said base section all about said stone section, said at least two stones having identical ones of said angled side wall sections, said at least two stones having their angled side wall sections disposed side-by-side in contact relationship, said at least two stones providing obstructions to straight continuous joints formed between said rectangular precast concrete stones.  
   
   
       12 . A precast concrete stone as claimed in  claim 11  wherein said stone section has rounded corners and irregular side edges resembling a real stone.  
   
   
       13 . A precast concrete stone as claimed in  claim 12  wherein said stones define joints between said side edges of adjacent stone sections and said adjacent top flat edge surfaces, and a fill material in said joints.  
   
   
       14 . A precast concrete stone as claimed in  claim 13  wherein said fill material is sand.
