Abstract
Retaining wall blocks and the walls made from such blocks are disclosed, wherein curved landscapes (i.e. curved profiles and sloping embankments) are easily accommodated without the use of mortar. As well, a modular system of blocks and their manufacture are disclosed wherein some blocks are used in vertical orientations and some in horizontal orientations.
Claims18
A block comprising:
- (a) a front wall;
- (b) a rear wall;
- (c) first side wall;
- (d) second side wall opposed to said first side wall;
- (e) an upper block planar surface;
- (f) a lower block planar surface;
- wherein said first side wall and said second side wall extend from said front wall to said rear wall to define a central through core extending through the block from said upper block surface to said lower block surface, and said core has an upper front rim defined . . . said upper block planar surface and a first front corner extending downwardly from said upper block planar surface, proximate the intersection of said first side wall and said front wall;
- (g) a first lug which extends downwardly from said lower block surface adjacent said first side wall, and has
- (A) a flat side portion flush with said first side wall and
- (B) a front portion which joins said first lug side surface at an angle of 90° or less and has a front rim.

A rectangular block comprising a first and second sub-block, wherein said first sub-block has:
- (a) a front wall;
- (b) a rear wall;
- (c) first side wall;
- (d) second side wall opposed to said first side wall;
- (e) an upper block planar surface;
- (f) a lower block planar surface;
- (g) a first lug which extends downwardly from said lower block surface adjacent said first side wall, and has
- (A) a flat side portion flush with said first side wall and
- (B) a front portion which joins said first lug side surface at an angle of 90° or less and has a front rim;
- (h) a through channel which extends on said block upper surface from said first side wall towards and terminates at said second wall, intermediate of said rear wall and said front wall;
- and wherein said second sub-block has:
- (a) a front wall;
- (b) a rear wall;
- (c) first side wall;
- (d) second side wall opposed to said first side wall;
- (e) an upper block planar surface;
- (f) a lower block planar surface;
- (g) a first lug which extends downwardly from said lower block surface adjacent said first side wall, and has
- (A) a flat side portion flush with said first side wall and
- (B) a front portion which joins said first lug side surface at an angle of 90° or less and has a front rim;
- and
- (h) a first blind channel which extends on said block upper surface from said first side wall towards said second wall, and a second blind channel which extends on said block upper surface from said second side wall towards said first wall, and both channels are intermediate of said rear wall and said front wall;
- and said first and second sub-blocks are created by splitting the block along the longitudinal middle thereof
