Interlocking building blocks for changeable modular assemblies
The invention relates to interlocking building blocks for changeable modular assemblies. The set of interlocking building blocks consists of a female block ( 1 ) and a set of male blocks ( 2 - 5 ), wherein the female block ( 1 ) has rectangular indentations ( 7 ) and the male blocks ( 2 - 5 ) fit inside the rectangular indentations ( 7 ) of female blocks ( 1 ), so that a female block ( 1 ) may simultaneously fit in its rectangular indentations ( 7 ) two male blocks ( 2 - 5 ), and a male block ( 2 - 5 ) may simultaneously fit inside at least two female blocks ( 1 ). In that way, each male block ( 2 - 5 ) simultaneously fills in at least half the rectangular indentations ( 7 ) of at least two female blocks ( 1 ) and thus fixedly connects said at least two female blocks ( 1 ). The set of interlocking building blocks further comprises a terminal block ( 6 ) to fill in empty spaces and provide straight edges on the assembly, and a filling block ( 11 ) to extend the assembly eight, width or length. The blocks are stackable and vertically stable but reversible and easy-to-handle. No additional tools or materials are required in order to build all kinds of tridimensional structures.
1. An interlocking system of one or more female building blocks and a set of male building blocks that engage forming unique, solid, strong and vertically and horizontally stable structures that are fit to be used as changeable modular assemblies such as interior walls, floors, furniture, exterior walls, outdoor furniture or outdoor construction, comprising: the one or more female building blocks ( 1 ) each comprising a semi-hollow cubical block with a flat bottom face and four side walls having one rectangular indentation ( 7 ) in each side wall, said indentations ( 7 ) having a depth equal to half the height of the cubical block and width equal to one third of the width of the cubical block; and the set of male building blocks ( 2 - 5 ) comprising one or more of each of four different types of male building blocks, the types of the set of male building blocks comprising two, three, or four rectangular projections ( 8 ) linked by a unique and solid interconnecting structure composed by one or two webs ( 9 ), wherein said rectangular projections ( 8 ) and said one or two webs ( 9 ) have twice the height of the indentations ( 7 ); wherein engagement of the one or more of each of the four different types of male building blocks with the one or more female building blocks in one or both axis without tools or glue provides structural strength and stability to the changeable modular assemblies;
wherein a third type of the four different types of male building blocks ( 4 ) consists of three said rectangular projections ( 8 ) arranged on three sides of a square and linked by two of said one or two webs ( 9 ), said two of one or two webs ( 9 ) connected perpendicularly to one another to form a cross-shaped structure wherein two opposite ends of one of the two of one or two webs ( 9 ) and one end of the other of the two of one or two webs ( 9 ) are each connected to one of the three rectangular projections ( 8 ), wherein said third type of the four different types of male building blocks ( 4 ) is configured to engage with four of the one or more female building blocks ( 1 ); and
wherein a fourth type of the four different types of male building blocks ( 3 ) consists of two said rectangular projections ( 8 ) arranged on two adjacent sides of a square and linked by two of said one or two webs ( 9 ), said two of one or two webs ( 9 ) connected perpendicularly to one another to form a cross-shaped structure wherein one end of each of the two of one or two webs ( 9 ) is connected to one of the two rectangular projections ( 8 ), wherein said fourth type of the four different types of male building blocks ( 3 ) out of the four different types of male building blocks is configured to engage with three of the one or more female building blocks ( 1 ).
2. The interlocking system of claim 1 , wherein a one of the male building blocks of the set of male building blocks ( 2 - 5 ) comprising two, three or four rectangular projections ( 8 ) which can simultaneously fit inside two, three, four or five female building blocks, fits inside at least two of the one or more female building blocks ( 1 ), and half the height of the rectangular projections ( 8 ) and half the height of one of the said one or two webs ( 9 ) of said male building block ( 2 - 5 ) is inside the at least two female building blocks ( 1 ), and a symmetrical portion extends outside the top surface of the female building blocks ( 2 ), such that said symmetrical portion extending outside the top surface of the female building blocks ( 1 ) can fit inside another at least two female building blocks ( 1 ).
3. The interlocking system of claim 1 , wherein a first type of the four different types of male building blocks ( 2 ) consists of two said rectangular projections ( 8 ) linked by one of said one or two webs ( 9 ) disposed between the two rectangular projections ( 8 ), wherein the first type of the four different types of male building blocks ( 2 ) is configured to engage with two of the one or more female building blocks ( 1 ).
4. The interlocking building blocks of claim 3 , wherein the one web ( 9 ) has a length which is two-thirds of the width of the cubical block.
5. The interlocking system of claim 1 , wherein a second type of the four different types of male building blocks ( 5 ) consists of four said rectangular projections ( 8 ) arranged on four sides of a square and linked by two of said one or two webs ( 9 ), said two of one or two webs ( 9 ) connected perpendicularly to one another to form a cross-shaped structure wherein each end of the two of one or two webs ( 9 ) is connected to one of the four rectangular projections ( 8 ), wherein said second type of the four different types of blocks ( 5 ) is configured to engage with five of the one or more female building blocks ( 1 ).
6. The interlocking system of claim 1 , further comprising a terminal block ( 6 ) consisting of an additional rectangular projection ( 8 ) the same shape as the rectangular projections of the set of male building blocks, linked to a terminal part ( 10 ), wherein a dimension of said terminal part ( 10 ) measured perpendicular to the additional rectangular projection ( 8 ) combined with the width of the said rectangular projections ( 8 ) is equal to half the width of the cubical block, and the height of the additional rectangular projection ( 8 ) and terminal part ( 10 ) is the same as the height of the cubical block.
7. The interlocking system of claim 1 further comprising a filling block ( 11 ) the same shape as two of the one or more female building blocks ( 1 ) arranged having the flat bottom faces disposed in contact with one another.
8. The interlocking system of claim 1 , wherein the interlocking building blocks are made of cork, cork-based materials or other material suitable for the type of modular construction in which the blocks are to be used.
9. The interlocking system of claim 1 , wherein the interlocking building blocks are made of a lightweight material comprising good resistance to mechanical loads, and having a mass density in the range of 100 Kg/m 3 to 200 Kg/m 3 .
10. The interlocking system of claim 1 , wherein each side wall of the one or more female blocks measures in a range of 80 mm to 700 mm.
