Stackable bricks and their procedures for stacking

Abstract

A rectangular stackable brick is provided having substantially parallel opposing top and bottom surfaces, substantially parallel opposing side surfaces and substantially parallel opposing end surfaces. The length of the brick is approximately twice the width of the brick so that the top and bottom surfaces each define first and second square regions. The top surface includes a first column which projects upwardly from the center of a first square region and a second column which projects upwardly from the center of a second square region. The bottom wall of the brick includes a recess sized and configured for receiving the first and second columns. The recess extends from an end wall along the center of the length of the brick sufficiently far so that the brick can be stacked upon other bricks of like construction.

Having identified the presently preferred best modes of practicing the invention, I claim:  
     
         1 . A rectangular stackable brick for constructing structural objects, the brick comprising: 
 a unitary object having six sides defining substantially parallel opposing top and bottom surfaces, substantially parallel opposing side surfaces and substantially parallel opposing end surfaces;    the distance between said opposing end surfaces defining the length of said brick, the distance between said top and bottom surfaces defining the height of said brick and the distance between said side surfaces defining the width of said brick;    said length of said brick being approximately twice the width of said brick so that the top and bottom surfaces each include first and second square regions;    said top surface including a first column which projects upwardly from the center of a first square region and a second column which projects upwardly from the center of a second square region;    said bottom surface including a recess sized and configured for receiving said first and second columns; said recess extending from an end surface along the length of said brick sufficiently far so that said brick can be stacked upon other bricks of like construction.    
     
     
         2 . The rectangular stackable brick of  claim 1  wherein said recess extends from an end surface and terminates at an edge wall.  
     
     
         3 . The rectangular stackable brick of  claim 1  wherein said edge was is semi-circular in shape.  
     
     
         4 . A structure constructed of a plurality of rectangular stackable bricks, each of said bricks comprising: 
 a unitary object having six sides defining substantially parallel opposing top and bottom surfaces, substantially parallel opposing side surfaces and substantially parallel opposing end surfaces;    the distance between said opposing end surfaces defining the length of said brick, the distance between said top and bottom surfaces defining the height of said brick and the distance between said side surfaces defining the width of said brick;    said length of said brick being approximately twice the width of said brick so that the top and bottom surfaces each include first and second square regions;    said top surface including a first column which projects upwardly from the center of a first square region and a second column which projects upwardly from the center of a second square region;    said bottom surface including a recess sized and configured for receiving said first and second columns; said recess extending from an end surface along the length of said brick sufficiently far so that said brick can be stacked upon other bricks of like construction.
