Abstract

An interlocking building block system is disclosed. The system may include a first building block, a second building block and an elongated connector. The first building block and the second building block may include a first recess and a second recess, respectively. The elongated connector may be configured to connect the first building block and the second building block. The elongated connector may include a first portion and a second portion connected to each other. The first portion may be configured to be inserted in the first recess and the second portion may be configured to be inserted in the second recess. Each of the first portion and the second portion may include an elongated wall and side walls. The elongated wall may include an elongated ridge at an elongated wall center portion disposed along an elongated wall length.

Claims (45)

1 . An interlocking building block system comprising:

a first building block comprises a first recess on a first building block face;

a second building block comprises a second recess on a second building block face; and

an elongated connector configured to connect the first building block and the second building block, wherein:

the elongated connector comprises a first portion and a second portion connected to each other,

the first portion is configured to be inserted in the first recess,

the second portion is configured to be inserted in the second recess,

each of the first portion and the second portion comprises an elongated wall and side walls, and wherein the elongated wall comprises an elongated ridge at an elongated wall center portion disposed along an elongated wall length.

2 . The interlocking building block system of claim 1 , wherein the first building block and the second building block are shaped as a cube or a truncated pyramid.

3 . The interlocking building block system of claim 1 , wherein the first recess and the second recess are dovetail recesses.

4 . The interlocking building block system of claim 1 , wherein a first portion shape complements a first recess shape, and wherein a second portion shape complements a second recess shape.

5 . The interlocking building block system of claim 1 , wherein each of the first recess and the second recess comprises recess side walls.

6 . The interlocking building block system of claim 5 , wherein at least one of the side walls and the recess side walls is polished with a Root Mean Square (RMS) surface finish in a range of 15 to 40 RMS.

7 . The interlocking building block system of claim 5 , wherein at least one of the side walls and the recess side walls has a textured surface.

8 . The interlocking building block system of claim 1 , wherein the first portion and the second portion form a unified integrated structure of the elongated connector.

9 . The interlocking building block system of claim 1 , wherein the first portion and the second portion have mirrored shapes.

10 . 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.

11 . The interlocking building block system of claim 1 , wherein each of the first portion and the second portion comprises a proximal end and a distal end, and wherein a proximal end width is greater than a distal end width.

12 . The interlocking building block system of claim 11 , wherein the first portion and the second portion are configured to be inserted into the first recess and the second recess via respective distal ends.

13 . The interlocking building block system of claim 1 , wherein the elongated wall is shaped as an elongated arc.

14 . An interlocking building block system comprising:

a first building block comprises a first recess on a first building block face;

a second building block comprises a second recess on a second building block face; and

an elongated connector configured to connect the first building block and the second building block, wherein:

the elongated connector comprises a first portion and a second portion connected to each other,

the first portion is configured to be inserted in the first recess,

the second portion is configured to be inserted in the second recess,

each of the first portion and the second portion comprises a proximal end and a distal end,

a proximal end width is greater than a distal end width,

the first portion and the second portion are configured to be inserted into the first recess and the second recess via respective distal ends,

each of the first portion and the second portion comprises an elongated wall and side walls, and

the elongated wall comprises an elongated ridge at an elongated wall center portion disposed along an elongated wall length.

15 . The interlocking building block system of claim 14 , wherein the first recess and the second recess are dovetail recesses.

16 . The interlocking building block system of claim 14 , wherein a first portion shape complements a first recess shape, and wherein a second portion shape complements a second recess shape.

17 . The interlocking building block system of claim 14 , wherein the first portion and the second portion form a unified integrated structure of the elongated connector.

18 . The interlocking building block system of claim 14 , wherein the first portion and the second portion have mirrored shapes.

19 . The interlocking building block system of claim 14 , wherein the first building block and the second building block are shaped as a cube or a truncated pyramid.

20 . An interlocking building block system comprising:

a first building block comprises a first recess on a first building block face;

a second building block comprises a second recess on a second building block face; and

an elongated connector configured to connect the first building block and the second building block, wherein:

the elongated connector comprises a first portion and a second portion connected to each other,

the first portion is configured to be inserted in the first recess,

the second portion is configured to be inserted in the second recess,

each of the first portion and the second portion comprises an elongated wall and side walls, and wherein the elongated wall is shaped as an elongated arc.
