Interlocking building block system

Abstract

An interlocking building block system is disclosed. The system may include a building block and an elongated connector. The building block may include a recess on a building block face. The elongated connector may be configured to connect with the building block. The elongated connector may include a first portion and a second portion connected to each other at an intersection line or a throat portion. The first portion or the second portion may be inserted in the recess. Each of the first portion and the second portion may include an elongated wall and side walls. The elongated wall may be slanted towards the throat portion such that a center point of the elongated wall is closer to the throat portion than side edges of the elongated wall.

 the first portion or the second portion is configured to be inserted in the recess, 
 each of the first portion and the second portion comprises an elongated wall and side walls, and wherein the elongated wall is slanted towards the intersection line such that a center point of the elongated wall is closer to the intersection line than side edges of the elongated wall. 
   
     
     
         2 . The interlocking building block system of  claim 1 , wherein the elongated connector further comprises a through-hole located in the elongated wall. 
     
     
         3 . The interlocking building block system of  claim 2 , wherein a shape of the through-hole is equivalent to a shape of the elongated wall. 
     
     
         4 . The interlocking building block system of  claim 3 , wherein the through-hole and the elongated wall are rectangular. 
     
     
         5 . The interlocking building block system of  claim 4 , wherein a length and a width of the through-hole is smaller than a length and a width of the elongated wall. 
     
     
         6 . The interlocking building block system of  claim 2 , wherein the through-hole has chamfered edges. 
     
     
         7 . The interlocking building block system of  claim 1 , wherein the elongated wall comprises an elongated ridge at an elongated wall center portion disposed along an elongated wall length. 
     
     
         8 . The interlocking building block system of  claim 1 , wherein the intersection line has a non-zero width. 
     
     
         9 . The interlocking building block system of  claim 1 , wherein a width of the intersection line is in a range of 1-20% of a height of the elongated connector. 
     
     
         10 . The interlocking building block system of  claim 1 , wherein the recess is a dovetail recess, and wherein a shape of the first portion or the second portion complements a shape of the recess. 
     
     
         11 . The interlocking building block system of  claim 1 , wherein the first portion and the second portion have mirrored shapes. 
     
     
         12 . The interlocking building block system of  claim 1 , wherein the side walls are slanted at a predefined angle relative to an elongated wall lateral axis. 
     
     
         13 . The interlocking building block system of  claim 1 , wherein the building block is shaped as a cube, and wherein at least one corner of the cube comprises a circular through-hole extending an entire length of the cube. 
     
     
         14 . The interlocking building block system of  claim 13 , wherein a top building block face and a bottom building block face of the building block further comprise a rectangular through-hole located at center portions of the top building block face and the bottom building block face. 
     
     
         15 . The interlocking building block system of  claim 14 , wherein the recess is disposed at a center portion of the top building block face or the bottom building block face, and wherein the recess is parallel to the rectangular through-hole. 
     
     
         16 . The interlocking building block system of  claim 14 , wherein the recess is perpendicular to the rectangular through-hole. 
     
     
         17 . The interlocking building block system of  claim 1 , wherein the building block is shaped as a truncated pyramid, and wherein at least one corner of the truncated pyramid comprises a cavity. 
     
     
         18 . The interlocking building block system of  claim 1 , wherein a slant angle of the elongated wall towards the intersection line is in a range of 2-7 degrees. 
     
     
         19 . A connector comprising:
 a first portion and a second portion connected to each other at an intersection line, wherein:
 the first portion or the second portion is configured to be inserted in a recess of a building block, 
 each of the first portion and the second portion comprises an elongated wall and side walls, and 
 the elongated wall is slanted towards the intersection line such that a center point of the elongated wall is closer to the intersection line than side edges of the elongated wall. 
   
     
     
         20 . A connector comprising:
 a first portion and a second portion connected to each other at an intersection line, wherein:
 the first portion or the second portion is configured to be inserted in a recess of a building block, 
 each of the first portion and the second portion comprises an elongated wall and side walls, and 
 the elongated wall is slanted towards the intersection line such that a center point of the elongated wall is closer to the intersection line than side edges of the elongated wall; and 
   a through-hole located on the elongated wall.
