Abstract

A building block includes at least one of a plug portion and a socket portion. The plug portion has two cantilevered tongues deflectable toward each other. Each cantilevered tongue includes a first engaging portion. The socket portion defines a chamber and has two second engaging portions. The plug portion and the socket portion are configured in such a way that the plug portion of one building block is insertable into the chamber of the socket portion of another building block, and the two cantilevered tongues of the building block deflect toward each other after insertion of the plug portion of the building block into the chamber of the socket portion of the other building block, which allows the first engaging portions of the building block to be engaged with the second engaging portions of the other building block, thereby connecting the two building blocks together.

First claim

What is claimed is:

1. A building block kit comprising:
a male building block comprising a plug portion, the plug portion comprising two cantilevered tongues that are spaced apart from and deflectable toward each other, each of the two cantilevered tongues comprising a first engaging portion at an end thereof;
a female building block comprising a socket portion defining a chamber and comprising two second engaging portions in the chamber;
wherein the plug portion and the socket portion are configured in such a way that the plug portion is insertable into the chamber, and the first engaging portions are engaged with the second engaging portions after the plug portion is inserted into the chamber, thereby connecting the male building block and the female building block together;
wherein the socket portion further comprises a block in the chamber, the block is configured to be received in a hollow space of the male building block after the plug portion is inserted into the chamber, so as to guide the male building block during insertion of the plug portion;
wherein the plug portion comprises a first main body that comprises three side walls that are connected to one another, and two inner plates arranged within a space defined by the three side walls and connected to the three side walls, the two cantilevered tongues protrude from one of the side walls that is connected to both of the other two side walls, each of the two inner plates defines a through hole, the two cantilevered tongues are respectively received in the through holes of the two inner plates.

2. The building block kit according to claim 1 , wherein the socket portion comprises two outer plates that are spaced apart from each other and corporately define the chamber, the two second engaging portions are respectively arranged on the two outer plates, the three side walls and the two inner plates corporately define two receiving spaces, the two outer plates are respectively received in the two receiving spaces when the male building block and the female building block are connected to each other.

3. The building block kit according to claim 2 , wherein the two inner plates corporately define the hollow space therebetween, the block is arranged between the two outer plates.

4. The building block kit according to claim 3 , wherein the through holes respectively communicate with the receiving spaces.

5. The building block kit according to claim 3 , wherein the hollow space has a rectangular cross section, and a cross section of the block is shaped and sized according to the cross section of the hollow space.

6. The building block kit according to claim 3 , wherein the one of the side walls from which the cantilevered tongues protrude defines a first orifice extending therethrough, and the block defines a second orifice corresponding to the first orifice.

7. The building block kit according to claim 2 , wherein the socket portion comprises a second main body, and the two outer plates protrude from the second main body.

8. The building block kit according to claim 7 , wherein the socket portion further comprises two additional outer plates protruding from the second main body, and the two additional outer plates are shaped and sized in a same way as the two outer plates, and extend in a direction perpendicular to an extending direction of the two outer plates, or in a direction opposite the extending direction of the two outer plates.
