MODES FOR CARRYING OUT THE INVENTION

[0042] A set of building blocks (FIG. 1) includes a base block (1) of six female sides, a connector block (3) that connects one base block to another base block, and a finish block (2) that connects to any of the open sides of the base block to finish the outward appearance of the block structure. A plurality of these blocks may be interconnected together to assemble toy structures, furniture, interior walls, architectural models, signage and many other structures that are built for functional, entertainment or educational purposes. An assembled structure made up of the interconnected blocks has a finished outward appearance and has passageways within the block structure created within the blocks themselves.

[0043] The base block (1) has six female sides wherein each side is adapted to accept a male side of a second different block. The base block is made up of a cross form (4 or 5) comprised of tubular projections (22), a skeleton block form (6 or 7), and connection components (21) connecting the cross form (4 or 5) to the skeleton block form (6 or 7). A second different block with at least four generally cylindrical projections extends normally outward from the base plate of the second block may be inserted into any of the six sides of the base block (1) and interconnect by frictional engagement. The relationship of this frictional engagement is between the generally cylindrical projections of the second block being inserted into the base block (1) wherein each generally cylindrical projection of the second block is engaged with at least one tubular projection (22) of the cross form (4 or 5) of the base block (1) and at least one side of the skeleton block form (6 or 7) of the base block (1). The second different block that connects to the base block may be the connector block (3), the finish block (2), or a block with similar projections to these. Such blocks may be releasable and connectable with each other.

[0044] In the preferred embodiment of the base block (1), the building block is substantially cubical in shape and has six female sides wherein one generally tubular projection (22) at each of the six sides extends normally from the general center of the base block (1). These six generally tubular projections (22) of the preferred embodiment base block (1) form together into one single integral cross form (4) as they come together in the general center of the block. At the edges of each face of the base block (1) are edge angles (20) which are positioned so the outside point of each angle is pointing towards the inside of the block. These angles at the edges of each face of the base block form a general square shape. These general square shapes made up of the edge angles (20) are formed together with each other as to make a single integral skeleton block form (6). The cross form (4) and the skeleton block form (6) are connected together with the connection components (21). In this preferred embodiment the connection components (21) are positioned in the general middle of each side of the base block (1), wherein when viewed from each side there are four connection components (21) that are connecting the cross form (4) to the skeleton block form (6). The cross form (4), the skeleton block form (6), and the connection components (21) are formed together as an integral unit and formed complete by a single injection molding process. Each of the six sides of the preferred embodiment base block (1) is positioned and shaped to accept the insertion of four generally cylindrical projections (26 or 29) extending outward from the base plate (25 or 28) of a second different block (2 or 3), so that each generally cylindrical projection (26 or 29) of the second block (2 or 3) is frictionally engaged with the general tubular projection (22) of the cross form (4) and the edge angles (20) of the skeleton block form (6) of the base block (1). The holes of the generally tubular projections (23) of the base block (1) extend therethrough the base block (1) to provide passageways from any side of the base block (1) to the opposite side of the base block (1).

[0045] In the preferred embodiment of the connector block (3), the building block is a square base plate (28) with four generally cylindrical projections (29) extending outward therefrom both sides of the base plate (28) and arranged in two rows of opposed projections to define a square on each side, from which a hole (30) on the base plate (28) is generally located in the center of the square made by the rows of projections. The four edges of the base plate (28) of this block are double beveled edges (27). The edges are double beveled to facilitate one face of the double beveled edge (27) mating with either another face of a double beveled edge (27) of a connector block (3) or a beveled edge (24) of a finish block (2). The thickness of the connector block (3) from the locations that it engages the base block (1) when connecting two base blocks (1) is generally twice the thickness of the finish block (2) from the location that the finish block engages the base block (1) and the outer face of the finish block (2). The connector block (3) could be made thicker throughout the base plate, however, for better plastic injection molding practices, the plate is cored out to achieve the desired thickness, thus the base plate extensions (31) and the circular base plate extension (32) are formed to create this thickness to engage with the base block (1) when connected.

[0046] The double beveled edges (27) of a connector block (3) can be double beveled at generally forty five degrees as to form a sharp point. However, the double beveled edges (27) may also flatten out at the outer most edge so as not to create a sharp point.

[0047] In the preferred embodiment of the finish block (2), the building block is a square base plate (25) with four generally cylindrical projections (26) extending outward therefrom one side of the base plate (25) and arranged in two rows of opposed projections to define a square. The four edges of the base plate of this block are beveled edges (24). The edges are bevel to facilitate the face of the beveled edge (24) mating with either another face of a beveled edge (24) of a finish block (2) or one of the faces of a double beveled edge (27) of a connector block (3). The thickness of the finish block (2) from the location that it engages the base block (1) to the outer face of the finish block (2) is generally half the thickness of the connector block (3) from the locations that the connector block (3) engages the base block (1) when connecting two base blocks (1).

[0048] The beveled edges (24) of a finish block (2) can be beveled at generally forty five degrees as to form a sharp point. However, the beveled edges (24) may also flatten out at the outer most edge so as not to create a sharp point. A variation of this may also be desirable where a small indention is made at these edges to facilitate an easier removal of the finish blocks (2) from the base blocks (1).

[0049] The finish block (2) can be made with many different colors, finishes, and may have connections added for attaching a phone/data, audio/video, coaxial, or universal serial bus outlet. The finish block (2) can be attached to every outermost side of every base block (1) once the block structure is assembled, so each side of every block can be a different color or design based on the finish blocks (2). The outward finish of the finish block (2) can be smooth, rough, or have a pattern on it. These finish blocks (2) give the user many opportunities for customizing the block structure.

[0050] These building blocks can be assembled together in a number of orientations to create many different structures. The connector blocks (3) connect one base block (1) to another base block (1). The four projections (29) on one side of a connector block (3) is inserted into one of the six sides of a base block (1). As the connector block (3) is inserted into the base block (1) the hole (30) of the connector block (3) is generally aligned with the hole (23) of the tubular projection (22) of the base block (1) providing a passageway between the two blocks. Then, another base block (1) can be attached to the other side of this connector block (3) by inserting the projections (29) of this side of the connector block (3) into a second base block (1). Again, the hole (30) of the connector block (3) is generally aligned with the hole (23) of the tubular projection (22) of this second base block (1). This type of building with the base blocks (1) and connector blocks (3) can be done to assemble many structures. After these blocks are assembled passageways exist within these blocks to add structural elements, wiring, lighting or anything else needed to run through these blocks and block structure. After the assembly is complete with the base blocks (1) and the connector blocks (3), the finish blocks (2) can be added to finalize the structure and make the outward appearance of it finished.

[0051] These building blocks are preferably made from resilient plastic material that is suitably adaptable for injection molding and each block made complete by a single injection molding process.

[0052] These building blocks can be made in various sizes, while still maintaining the general shape and invention described. Each size may have some advantages to it. The smaller sizes may be more suitable for toy structures and may be adaptable with other toy blocks already on the market. The larger sizes may be more suitable for making larger structures. All sizes will have the capabilities of creating passageways through the blocks, but the larger the block size gets the larger the passageways will be capable of getting within the blocks that may allow more capabilities.

[0053] While the preferred embodiment of the present invention is for the base block (1) to be a general cube shape and the connector block (3) and the finish block (2) to have general square plates, these building blocks may have different shapes than described while still maintaining the invention described. The base block (1) of the preferred embodiment is comprised of a cross form (4) that is a six-way cross form, meaning it has six generally tubular projections (22) that make up the cross form. This cross form may be extended to be a ten-way cross form, a fourteen-way cross form (5), a eighteen-way cross form, and so on. Every time it is extended, four more tubular projections are added to the cross form to make the extension. The connector block and the finish block would be extended to correspond to the cross form, so as to make the base plates of these blocks generally rectangular in shape and the generally cylindrical projections of these blocks to be shaped and positioned to correspond with the insertion of the extended cross form.

[0054] While embodiments of the present inventions have been explained with reference to the examples above, the embodiments are non-limiting examples for illustrating the present inventions and should not be construed as to limit the scope of the invention. While the above building blocks have been explained with reference to being molded from plastic, it will be appreciated that these building blocks can be molded from other materials such as concrete, metal, or some other moldable material; or can be made from wood or metal components without the loss of generality.
