Building blocks and rear interlock connector therefor

1. An interlock connector for interlocking building blocks for being assembled so as to provide a wall structure, the building blocks having respective front surfaces for defining a front façade of the wall structure and having respective rear surfaces with at least one respective horizontal groove, the building blocks being arranged with at least a first building block being adjacent to a second building block, the interlock connector comprising:

three separate connector bodies being interconnected, wherein of one of the three similar and separate connector bodies acts as a backing connector body connectively receiving a first one and a second one of the other two of the three separate connector bodies;

each of the connector bodies having a rectangular configuration defining opposite connecting sections and opposite lateral sides, each connecting section defining an opening near each lateral side thereby defining a median section therebetween and a finger portion at each lateral side being spaced apart from the median section, the median section having a cylindrical external edge, each of the openings having a relatively narrower outer portion thereof and a relatively wider inner portion thereof, each opening being circumscribed by inner walls which form deformable clamping elements;

the backing connector body defining at one of the connecting sections thereof the openings comprising first and second openings, the first opening receiving one connecting section of the first connector body being clamped thereby by the clamping elements defined by the first opening, the other connecting section of the first connector body providing for being inserted in the rear surface horizontal groove of the first building block, the second opening receiving one connecting section of the second connector body being clamped thereby by the clamping elements defined by the second opening, the other connecting section of the second connector body providing for being inserted in the rear surface horizontal groove of the second building block.

2. An interlock connector according to claim 1 , wherein the building blocks are arranged in vertical columns with one of the first or second building blocks being an upper building block and the other of the first or second building blocks being a lower building block, the upper building block resting on the lower building block.

3. An interlock connector according to claim 2 , wherein when the interlock connector is mounted to the upper and lower building blocks, the first and second bodies provide for positioning the upper and lower blocks with respect to each other such that the front faces of the upper and lower blocks are offset with respect to one another.

4. An interlock connector according to claim 1 , wherein the backing connector body provides for being connected to a third building block of the building blocks.

5. An interlock connector according to claim 1 , wherein the backing connector body provides for being connected to another interlock connector comprising first and second bodies.

6. An interlock connector according to claim 1 , further comprising a fourth body connected to the backing connector body.

7. A kit for building a wall structure comprising:

at least two building blocks for being assembled so as to provide the wall structure, the building blocks having respective front surfaces for defining a front façade of the wall structure and having respective rear surfaces with at least one respective horizontal groove; and

at least one interlock connector as defined in claim 1 ;

wherein insertion of the first and second connector bodies in the respective rear surface horizontal grooves of the first and second building blocks provides for interlocking the first and second building blocks.

8. A wall structure comprising:

at least two building blocks being assembled so as to provide the wall structure, the building blocks having respective front surfaces for defining a front façade of the wall structure and having respective rear surfaces with at least one respective horizontal groove; and

at least one interlock connector as defined in claim 1 ;

wherein insertion of the first and second connector bodies in the respective rear surface horizontal grooves of the first and second building blocks provides for interlocking the first and second building blocks.

9. A method of building a wall structure comprising:

providing at least two building blocks having respective front surfaces for defining a front façade of the wall structure and having respective rear surfaces with at least one respective horizontal groove;

assembling the at least two building blocks so as to provide the wall structure;

providing at least one interlock connector as defined in claim 1 ; and

mounting the at least one interlock connector to the at least two assembled building blocks by inserting the first and second connector bodies in respective rear surface horizontal grooves of the first and second building blocks provides for interlocking the first and second building blocks.
