Toy block cube filling puzzle

Abstract

Toy block cube filling puzzle using transparent cube containers and using 8 tetrahedron blocks as a first group and 32 one eighth of octahedron blocks as a second group. When the blocks from the first group are assembled with one vertex of each block meeting at the center of the cube the second group can be used to completely fill the cube without voids. When 8 blocks from the second group each share a vertex at the said center the remaining 32 blocks can completely fill the cube again. When using a cube filled with one block from the first group and four from the second and each having different colors and paired up with a mirrored adjacent copy of this assembly, 2 blocks are given color change to give 7 colors. Additional pairs can be arranged to form infinite sized shapes in perfect order in three dimension and color.

Description

BACKGROUND OF THE INVENTION

Similar inventions have been made in the past U.S. Pat. No. 4,461,480 shows the octahedron made of one eighth sections and describes a configuration using 8 cubes stacked together to form a larger cube assembly of pieces. It also describes some of the pieces being coupled together. U.S. Pat. No. 1,471,943 shows a thin wall cube and a removable top to be made of any material for containing a toy block assembly. U.S. Pat. No. 5,660,387 shows blocks inside a transparent housing such as a cube but do not show a 40 block assembly as described in the following invention.

SUMMARY OF THE INVENTION

The invention relates to a simplified toy block cube filling puzzle containing a total of 40 blocks (also called geometric parts or pieces) with 32 blocks equal in size and shape which are to be called OCTA pieces and 8 blocks equal in size and shape to be called TETRA pieces. The blocks called OCTA pieces are each a one eighth portion of regular octahedron, this polyhedron shape is sized to easily slide into a thin wall transparent cube container with each of the 6 vertices meeting perfectly at the centre of each of the inside surfaces of the said cube container with the top surface removed for an opening. By slicing through 4 vertices of said octahedron in each of the X, Y and Z axis the 8 OCTA pieces are produced that are perfectly equal in size and shape and this combination of pieces have a sliding fit to the inside surface of the cube. By starting with an octahedron assembly inside the cube we are now able to size a block to form a tetrahedron this is done by forming a tetrahedron with each of its 4 faces equal in size to the triangular face of the octahedron which gives us the TETRA piece. It is now possible to form a regular tetrahedron to fit perfectly with a sliding fit to the inside of the cube by adding 4 TETRA pieces to the 2 opposite faces of the lower half of the octahedron and its 2 opposite faces of the upper half rotated 90 degrees. There are 4 faces of the octahedron unused these are to be a different color to the 4 faces already used so as to be easier for children to follow the easy steps. Now a dual-tetrahedron can be formed by adding 4 more TETRA pieces with a different color to the 4 unused faces of the octahedron and a perfect 8 pointed star can be formed with each of the 8 points aligning perfectly to the 8 vertices of the inside surface of the cube container and having a sliding fit. There are now 4 spaces around each of the X, Y and Z axis between the 8 pointed star and the inside surface of the cube, these spaces may be accommodated by 24 more OCTA pieces using 8 OCTA pieces for each axis and be of 3 different colors to show balance and beauty. We shall call this 40 piece cube arrangement as a PLATO cube arrangement as it reveals the octahedron and 2 tetrahedrons which are platonic solids.

By removing all of the 40 blocks from the central octahedron configuration the 8 corners of the cube may be accommodated by the 8 OCTA pieces that were used for the octahedron. The 8 TETRA pieces can be added to the faces of the 8 corner OCTA pieces to make each vertex of each TETRA piece meet perfectly at the center of the cube container. This assembly will expose 6 four sided pyramid cavities on each face of the inside surface of the cube container and by adding the remaining 24 OCTA pieces 8 of the pieces in each of the X, Y and Z axis once more a complete fill of the cube can be achieved. By using separate color OCTA pieces for each axis the filled cube will show beauty and balance. If the 8 corner OCTA pieces are removed we will be left with a perfect cuboctahedron. We shall call this 40 piece cube arrangement as the BUCKY cube arrangement as Mr. Buckminster Fuller described the Cuboctahedron inside a cube with a Vector Equilibrium centre.

The color arrangement is kept simple to make it easy for children to follow the instructions. The octahedron (8 OCTA pieces) should be balanced with 4 pieces of one color and 4 pieces of a second color, two tetrahedron assemblies (8 TETRA pieces) with a separate color also, the remaining 24 blocks (OCTA pieces) to be 8 blocks of one color, 8 of another color and the remaining 8 of the last color, using a total of 7 colors all told. Support means are provided to accommodate 2 transparent cube containers with a lip provided to locate into a groove provided on 2 opposite sides of each cube container an accommodation is provided to house a DVD containing instructions. The instructions are kept very simple to follow. The cube assembly is displayed centrally and the 32 OCTA pieces are displayed to be used or unused at different steps at one side and the 8 TETRA pieces are displayed the same on the opposite side.

An alternate assembly to achieve the same results is revealed by splitting the 40 piece cube arrangements into 8 smaller cubes each of these cubes contain one TETRA piece and four OCTA pieces. This 5 piece cube is old art but it will not achieve the said 40 piece BUCKY cube arrangement and 40 piece PLATO cube arrangement unless a mirrored copy of said 5 piece cube is provided so as to make a pair. Each cube assembly of this said pair be distinguished by color and one cube is provided with 4 OCTA pieces and the TETRA piece with different colors, the second cube to form the pair having one OCTA piece with a different color and the TETRA piece of a different color, this will give each pair 7 different colors. We will call the cubes that make up a pair of 5 piece cubes as a CHICO cube and a CHICA cube as if they were a male assembly and a female assembly. It is essential that the two cubes of the pair be distinguished by color for assembly because when a 40 piece cube assembly is made out of 4 of these pairs the only indication of knowing a CHICO cube from a CHICA cube is the difference in color making up one corner being that of an OCTA piece, the TETRA pieces are hidden. When CHICO and CHICA cubes are assembled to make a 40 piece cube assembly the CHICO cube is always adjacent to a CHICA cube in any axis. It is very simple to assembly cubes together because of the one corner being distinguishable by color and it is possible with the correct assembly of CHICO to CHICA cubes to repeat to infinity and form a perfect 3 dimensional array without voids 3 separate octahedrons each made of a different color with a fourth octahedron split into 2 colors being central to 2 tetrahedrons of different color making dual tetrahedrons.

There is another advantage of this CHICO and CHICO arrangements in that cutting planes can be made in the X, Y, and Z axis and also cutting planes can be provided using the orientation of the 4 faces of the TETRA pieces. By splitting the assemblies of pieces along the faces of the TETRA pieces many very interesting shapes can be formed and some semi-regular polyhedrons also. A dual tetrahedron can be made to an infinite size when 8 forty piece cube assemblies are added to form a larger cube as long as the color arrangements are kept in the correct orientation, each tetrahedron will increase in size yet will still keep to the same color arrangement.

If it is desired to have a cutting plane diagonally from two opposite faces as may be needed for forming the faces of some semi-regular polyhedral shapes. The OCTA pieces and TETRA can be split into 2 perfectly matching halves and these pieces may be re-oriented to any diagonal face between any two opposite faces of the CHICO or CHICA cube. These smaller pieces could be used instead of the 5 pieces of the CHICO or CHICA cube assemblies but would make a more complicated puzzle, therefore just a few of these pieces may be added to a kit if desired.

The transparent thin wall cubes are also shown with interconnecting means to prevent an assembly of cubes from falling apart.

The thin wall cube container can be any size and the blocks may be made any size using wood with color or by using plastic or made magnetic. The cube container can also be located full of blocks on a support means that runs on wheels for small children to play with.

The left display of pieces shows 23 OCTA pieces 7a unused and 9 OCTA pieces 7u used and the right side display show 8 TETRA pieces 11u used with grommets 9 unused. Also shown are three axes X, Y, and Z this is an indication of how 8 OCTA pieces 7a may be used around each axis of the cube container 7a to fill the unused spaces and completely fill the cube container 1a as shown in FIG. 7 14. It is essential that the 8 OCTA pieces situated in the X axis are the same color being a fifth color, the 8 OCTA pieces in the Y axis of a sixth color and 8 OCTA pieces around Z axis being of a seventh color. Also shown are the OCTA pieces 7u in the left display and TETRA pieces 11u in the right side display totally used with just the grommets 9 unused.

(e) Description of FIG. 8 and FIG. 9.

FIG. 8 shows the transparent cube container 1b, this cube container is shown with the blocks rearranged as shown with the eight TETRA pieces 11 positioned with each apex meeting at the center point C of the cube and forming a perfectly balanced shape 15. This cube arrangement we call the BUCKY cube arrangement. The left side display shows all OCTA pieces 7a unused and the right side display shows all TETRA pieces 11u all used just leaving the grommets 9 unused.

FIG. 9 shows shape 16 which is similar to FIG. 8 but also shows 8 OCTA pieces 7a that have been added to fill the 8 corner spaces of the cube container 1b. The OCTA pieces are arranged so that the corners with the same color are diagonal to each other. We have 6 pyramid shaped cavities 17 at each cube face. The left display of pieces shows 8 OCTA pieces 7u used with 24 OCTA pieces 7a unused. The right side display of pieces shows all TETRA pieces 11u used and grommets 9 unused.

FIG. 10 shows the cube container 1b completely filled with pieces 18. The pyramid shaped cavities have been filled with 4 OCTA pieces 7a on each face. The front and back faces will each have 4 OCTA pieces of the same color being the fifth color, the left and right faces being the sixth color and the top and bottom faces using the seventh color. This arrangement is a 40 piece BUCKY cube arrangement.

FIG. 11 shows 8 cube containers 1b with 40 piece BUCKY arrangements making up a larger cube of 320 pieces. The cubes are arranged so that each face making up the face of the larger cube has matching colors except for the corner OCTA pieces 7a their 2 colors must always be adjacent, this is essential to ensure that the TETRA pieces which are hidden behind the OCTA pieces always keep their correct orientation and color. Eight of the 320 piece cubes can make a larger cube and so on to infinity.

(g) Description of FIG. 12, FIG. 13 and FIG. 14

FIG. 12 shows an illustration of 8 cube containers 1a abutted together to form an array of 8 eight pointed stars 13. The OCTA pieces have been taken away except for the central octahedrons of 2 colors which are hidden by all the TETRA pieces 11.

FIG. 13 shows an illustration of 8 cube containers 1a abutted together to form a larger cube of eight PLATO 40 piece cube assemblies 14, they can be split along the TETRA piece 11 faces to form a different shape as shown. The new face 21 will show many different color faces 11, 7a and when opposite sides are split similarly the arrangement of colors will match in perfection.

FIG. 14 shows an illustration of an eight pointed star 19 made of 8 cubes 1a, the pieces have been split down into tetrahedrons 12 of one color and tetrahedrons 12b of another color they each reveal faces 7a of the central octahedrons. As long as the 40 piece cube arrangements are abutted together in the correct orientation and matching colors, it is possible to form many other polyhedral shapes with a balanced arrangement of color and geometry.

Description of FIG. 15, FIG. 16 and FIG. 17

FIG. 15 shows the alternative arrangement of using CHICO and CHICA cubes also shown in FIG. 1b. In this illustration the CHICO cubes 20a and CHICA cubes 20b are arranged to form two BUCKY cube 18 arrangements and one PLATO cube 14 arrangement. The relationship between the two said cube arrangements can now be observed. Two little icons have been provided to illustrate each centre of the two different cube arrangements, the first being a little sphere 21, this little sphere is like the two color octahedron that forms the centre of the PLATO cube arrangement. The second icon 22 shows a small sphere indicating 12 vectors of the Vector Equilibrium as described in Mr. Buckminster Fullers work with the Cuboctahedron. Note that any corner vertex of a BUCKY cube can be a centre of a PLATO cube and any corner vertex of a PLATO cube can be a centre of a BUCKY cube arrangement of pieces.

FIG. 16 shows the pair of 5 piece cubes we call CHICO 20a and CHICA 20b each cube contains four OCTA pieces 7a but we will change the number of one OCTA piece from 7a to 7b on the CHICO cube 20a and one OCTA piece from 7a to 7c on the CHICA cube 20b these are the two OCTA pieces that make the CHICO and CHICA cubes easy to identify and keep to the correct orientation and color display that can tessellate to infinity. The icon 21 show the centre of a PLATO arrangement that can be made if pairs of cubes 20a and 20b are arranged about this point, icons 22 indicating BUCKY cube centers.

FIG. 17 shows the pair of 5 piece cubes as in FIG. 16 with the 3 OCTA pieces 7a removed from each cube to show a TETRA piece 11a abutted to OCTA piece 7b in the CHICO cube 20a and TETRA piece 11b abutted to OCTA piece 7c in CHICA cube 20b. It can be seen that the assembly of pieces in the CHICA cube is a mirrored assembly of the CHICO cube, the TETRA piece 11a must be a different color to TETRA piece 11b. The OCTA pieces 7b and 7c have their own color so as to make it easier for identifying between the two cubes. The remaining OCTA pieces will be made up of 3 colors with the CHICO AND CHICA cubes having opposite matching colors. The total colors of the CHICO and CHICA pair of assemblies will be seven colors.

FIG. 18 shows an arrangement of a pair of 5 piece cubes that have a diagonal split 25 this can be achieved if the OCTA pieces 7a are made into 2 halves 23 and TETRA pieces 11 made into two halves 24. If all 5 pieces are split this way they can be rearranged for a diagonal spit in all possible orientations. This may be the solution for forming some special polyhedral shapes.

Description of FIG. 19

FIG. 19 is an illustration of three transparent cubes 25 that have been provided with interconnecting means. Each cube 25 is provided with 2 tongues 26, each tongue is provided with two lips 27, each lip is provided with an aperture 28 to receive the tongue of an additional cube 25 to secure the two cubes together snugly. The bottom of each transparent cube 25 is also provided with four apertures 29 to receive the tongues 26 and lips 27 of additional cubes when place on top of each other, forming a seating for correct orientation. These said means can help to prevent an assembly of cubes such as 8 cubes that make a larger cube from falling apart.
