Abstract
A mechanical octahedron puzzle arrangement of the present invention is comprised of a plurality of radially interlocking generally octahedrally and tetrahedrally shaped components, for permitting rotation of a plane of such components about an axis perpendicular to that plane of components. The rotatable planes define a changeable collective face of the puzzle arrangement. The puzzle comprises an inner core octahedral member, a first radially innermost transitional layer of the components, and a second layer of components, each having an outer face of equilateral triangular shape, wherein a planar portion of the components may be rotated in 120 degree increments about an axis perpendicular to the planar portion of components to effect a change in the colors of each collective face of the octahedron puzzle arrangement, so that when the faces are twisted, the color markings on the exposed faces are scrambled.
Description
- 1. Field of the Invention
- The present invention relates to mechanical puzzles and more particularly to a manipulable octahedrally shaped puzzle.
- 2. Prior Art
- Mechanical puzzles have been around for many, many years. They have delighted generations of individuals who enjoy manipulation of clever mechanisms which are designed to present an intellectual challenge to its user. The most notable of these is a cube shaped puzzle known as “Rubiks Cube” or “Magic Cube”. It has been an international favorite for decades.
- Another puzzle concept is shown in U.S. Pat. No. 4,451,039 to Hewlett, Jr. This mechanical puzzle design is the shape of a regular octahedron. This puzzle design consists of a plurality of tetrahedra and octahedra which are retained as a unit and which permits the faces of the puzzle to be changed by their rotation about an axis perpendicular to their particular plane. This particular arrangement however, relies only upon one spherical boundary within the plurality of layered components of this puzzle, to hold the pieces together. This single spherical “underlayer” in between the core and its outer layer means that the puzzle as designed, is more susceptible to damage and its parts are less robust than they should be. Such pieces may break or the puzzle itself may fall apart.
- It is the object of the present invention to provide an octahedral mechanical puzzle which overcomes the disadvantages of the prior art.
- It is a further object of the present invention to provide an octahedral mechanical puzzle with an improved inter-linkage arrangement between the layers of the components so as to permit the present puzzle invention to work more efficiently with improved life.
- It is still yet a further object of the present invention to provide an octahedral mechanical puzzle whose components are more robust, more resilient when those components are assembled and which will provide better security and resistance to breakage.
- The present invention comprises a mechanical puzzle arrangement which is in the shape of a regular octahedron. This mechanical puzzle has a plurality of subcomponents the exterior of which each defines an equilateral triangle each of which may be divided into a plurality of planes perpendicular to the respective equilateral triangle. Those faces of the components of each plane comprise nine smaller equilateral triangles which are the faces of the components consisting of octahedra and tetrahedra.
- The puzzle of the present invention comprises a plurality of radially secured components attached to an inner core. The preferred embodiment of the inner core generally comprises a generally octahedral shape having each of its eight triangularly shaped faces having a hub/bore thereon. Each hub is arranged to receive an axis pin about which radially outwardly successive pieces will rotate. The inner core member in a further embodiment may be reduced to an 8 armed “spider”, the ends of the arms corresponding to the hubs/bores on the surface to the core octahedral as presently described in the preferred embodiment. In this alternative embodiment, the core tetrahedral members may also be reduced to rotatable pins with triangular curvilinear caps for retaining further parts. Thus in this further embodiment, an 8-armed “spider” with rotatable arms would have generally triangularly-shaped retaining caps thereon. Returning to the preferred embodiment, a flattened tetrahedral member of generally triangular configuration has a bore extending therethrough. The first tetrahedral member is rotatably attached to the hub of the octahedral core member. The flattened tetrahedral member has a curvilinear radially outermost surface and three curvilinear retaining edges. The curvilinear retaining edges are parallel with their respective edges of the curvilinear base of the tetrahedral member. A flattened tetrahedral member is disposable radially outwardly on each triangular face of the core octahedral member. The bore through each tetrahedral member is in co-axial alignment with the bores through the hubs on the face of each triangular surface of the core octahedral member. Thus there is defined for rotation four axes passing through the core octahedral member.
- The arrangement also includes a generally octahedral outer member having two triangular outer faces and four side faces with curvilinear lowermost edges and a central core attached to an elongated curved foot. This part may otherwise be described as an octahedron with four circular or arcuate slices removed from their inner surfaces. That curved foot has a curvilinear outermost surface thereon defining a pair of curved edges. The curved foot is arranged to slidably engage radially under the curvilinear retaining edges of the flattened tetrahedral members. The arrangement includes a tetrahedral outer member having one triangular outer face, and having a curvilinear trapezoidal foot of trapezoidal configuration. The trapezoidal foot comprises a base portion of the tetrahedral member and is offset with respect to the triangular side portion thereof. The trapezoidal foot of the tetrahedral outer member has non-parallel sides which slidably mate radially under the outermost curvilinear retaining edges of the octahedral member having two triangular outer faces.
- The puzzle arrangement includes an octahedral vertex member that is arranged to be disposed at each vertex of the octahedron puzzle. The octahedral vertex member has four triangular face portions and four side trapezoidal faces. The trapezoidal faces are unitary with a generally square shaped foot having a curvilinear upper surface. The square shaped curvilinear foot has curvilinear edges which also slide radially under the outermost retaining edges of the octahedral outer member with two triangular outer faces and under the retaining edges of the outer tetrahedral members with one triangular face, as any part of the face of the octahedron puzzle is rotated about its respective rotational axis going through its respective hub/bore at the core octahedral member.
- The flattened tetrahedral member rotates on each respective face and hub of the core octahedral member about a connecting pin or axis extending into the hub/bore thereadjacent. The octahedral outer member with two triangular faces has its curvilinear edge of its respective foot slide under the respective curvilinear retaining edges of the flattened tetrahedral member. The tetrahedral outer member mates along side the octahedral outer member so that its foot engages under the outmost retaining edge of octahedral outer member. The tetrahedral outer member is mated adjacent each side of the octahedral vertex member so that each respective curvilinear foot is adjacent to one another.
- In the assembly of the octahedral puzzle, two spherical boundaries as defined by the collective radially spaced apart curvilinear retaining edges of the flattened tetrahedral curvilinear member and the respective radially outwardly adjacent curvilinear edges of the octhedral outer members and its associated radially outer components to define those two spherical boundaries to provide a superior locking relationship and slidability there between of their respective components.
- The invention thus comprises an octahedron puzzle arrangement comprised of a plurality of radially interlocking components, for permitting rotation of a plane of such components about an axis perpendicular to the plane of components to define a changeable collective face of the puzzle arrangement. The puzzle comprises an inner core octahedral member, a first radially innermost transitional layer of the components, and a second layer of the components, each component of the second layer having at least one face of triangular shape, wherein a planar portion of the components may be rotated about an axis perpendicular to the planar portion of components to effect the change in the collective face of the octahedron puzzle arrangement.
- The second layer of the components are arranged in an overlapping array with respect to the innermost transitional layer of the components. A plane of the second layer of components are rotatable with respect to an adjacent plane of components in the second layer. The puzzle in one preferred embodiment has an innermost core octahedral member having eight triangular faces thereon, each of the faces having an axis bearing bore therein. Each of the faces of the innermost core octahedral member has a flattened tetrahedral member rotatably secured thereon, each flattened tetrahedral member has a curvilinear edge for slidable retention of a further component thereunder. The puzzle includes an octahedral outer member with two triangular faces and with a curvilinear foot portion for engagement with the curvilinear edge of the flattened tetrahedral member. The puzzle includes a tetrahedral member having a curvilinear foot for placement adjacent a further outer component of the puzzle. The puzzle includes an octahedral vertex member having a curvilinear foot for placement at a corner of the collective faces of the puzzle arrangement. The flattened tetrahedral member comprises the first transitional layer rotatable about the inner core octahedral member. The octahedral member, the outer tetrahedral member and the octahedral vertex member comprise the second layer of components.
- The invention also comprises a mechanical octahedron puzzle arrangement comprised of a plurality of radially interlocking components, for permitting rotation of a plane of such components about an axis perpendicular to the plane of the components, to define a changeable collective face of the puzzle arrangement, comprising: an inner core member; a first radially innermost transitional layer of the components secured to the inner core member; and a second radially outer layer of the components, each of the components having an outer face to collectively define a plane of the puzzle arrangement, wherein a portion of the second layer of components may be rotated about an axis perpendicular to the plane of the puzzle arrangement, to effect the change in said collective face of the octahedron puzzle arrangement. The second layer of the components may be arranged in an overlapping array with respect to the innermost transitional layer of the components. The inner core member may comprise an arrangement of intersecting hubs, each of the hubs defining a bore therethrough, about which bore the components will rotate. A pair of hubs are preferably opposed to one another and define an axis through the inner core member. The inner transitional layer of components preferably have a smaller component engaging radius than the outer layer of components.
- In the present invention, the inner core tetrahedral components engage only the outer edge octahedral components. These in turn engage the radially adjacent outer tetrahedral and vertex components, as opposed to the prior art Hewlett, Jr. reference U.S. Pat. No. 4,451,039, wherein the inner core tetrahedral tetrahedral components engage all of the radially outer components. In the present invention it is this separation of functionality and consequent second radially-spaced transition layer that provides the present invention with a more robust design both in its individual components themselves and the interconnection mechanisms between those components.
- The invention may further comprise an octahedral puzzle arrangement comprised of a plurality of radially interlocking tetrahedral and octahedral components for permitting rotation of a plane of such components about an axis perpendicular to said plane of components, comprising: an inner core octohedral member having eight faces; an inner core of tetrahedral members each rotationally attached to one of said faces of said octahedral core member; a second radially outwardly disposed layer consisting of octahedral components having portions extending radially inward of and under and captured by the inner core of tetrahedral members, the tetrahedral members each having two faces displayed on a surface of the octahedral puzzle; and a third radially outwardly disposed layer consisting of tetrahedral and octahedral members, each of the members of the third layer having at least one face displayed on the surface of the octahedral puzzle. The third layer of tetrahedral and octahedral members preferably have a portion extending radially inwardly to be captured by a portion of the components comprising the second layer without interfering with the core tetrahedral members. The inner core octahedral member has a means for attaching a core tetrahedral component on each of the faces thereon. The core tetrahedral members may have a triangular cap for radial securement and rotational freedom of adjacent edge octahedral members. The edge octahedral members are radially secured and are permitted rotational freedom by the core tetrahedral members. The edge octahedral members each have an undercut portion spaced radially outwardly from the core tetrahedral members for radial securement of an adjacent surface tetrahedral and a surface octahedral. The surface tetrahedral are radially secured to the puzzle arrangement by an arrangement of feet thereon extending radially inwardly of the edge octahedral. A vertex octahedral member is preferably radially secured to the puzzle arrangement by an arrangement of feet thereon extending radially inwardly of the surface tetrahedral and the surface octahedral members. The inner core octahedral member may be an eight armed spider member core tetrahedral members each may consist of an extension to an arm of the eight armed spider member.

Thismechanical puzzle arrangement 20 has a plurality of subcomponents, the planar exterior of each side defines anequilateral triangle 22 each of which may be divided into a plurality of planes perpendicular to the respectiveequilateral triangle 22. Those faces of the components of each plane comprise nine smallerequilateral triangles 24 which are the faces of the components consisting of octahedra and tetrahedra. - The puzzle of the present invention comprises a plurality of radially secured components attached to an
inner core 26, as shown inFIG. 2 . Theinner core 26 may comprise a center such as for example, an octahedron having each of its eight triangularly shaped faces 28 having a hub/bore 30 thereon, (or alternatively, a “spider-like” set of arms, seeFIGS. 13 and 14 , comprising those hubs/bores 30, wherein each opposed pair of hubs/bores 30 defining an axis of thepuzzle arrangement 20. Each of the eight hub/bores 30 are arranged to receive an axis pin (not shown for clarity) about which radially outwardly successive pieces will rotate. A flattenedtetrahedral member 32 of generally triangular configuration, as shown inFIG. 3 , has abore 34 extending therethrough. The firsttetrahedral member 32 is rotatably attached to the hub/bore 30 of theoctahedral core member 26, as represented inFIG. 7 . The flattenedtetrahedral member 32 has a curvilinear radiallyoutermost surface 36 and three curvilinear retaining edges 38. The curvilinear retaining edges 38 are parallel with theirrespective edges 40 of the curvilinear base 42 of the flattenedtetrahedral member 32, as shown best inFIG. 3 . A flattenedtetrahedral member 26 is disposable radially outwardly on eachtriangular face 28 of thecore octahedral member 26, by apin 44, as shown inFIG. 7 . Thebore 34 through eachtetrahedral member 32 is in co-axial alignment with the bores through thehubs 30 on theface 28 of each triangular surface of thecore octahedral member 26. Thus there is defined for rotation four axes “A” passing through thecore octahedral member 26, as represented inFIG. 2 . - The
arrangement 20 also includes an octrahedralouter member 46, as shown inFIG. 4 having two triangularouter surfaces 48 and fourside surfaces 50 with curvilinearlowermost edges 52 and a central core 54 attached to an elongatedcurved foot 56. Thecurved foot 56 has a curvilinearoutermost surface 58 thereon, as shown inFIG. 4 , defining a pair of curved edges 60. Thecurved foot 56 is arranged to slidably engage radially under the curvilinear retaining edges 38 of the flattenedtetrahedral members 32 when thepuzzle arrangement 20 is assembled. Thepuzzle arrangement 20 includes a component identified as a tetrahedralouter member 62 which has a curvilineartrapezoidal foot 64 of trapezoidal configuration and a triangular face 66 and a trapezoidally shapedside face 68, as represented inFIG. 5 . Thetrapezoidal foot 64 comprises a base portion of the trapezoidaltriangular member 62 and is offset with respect to the triangular face 66 portion thereof. Thetrapezoidal foot 64 of the tetrahedralouter member 62 hasnon-parallel sides 70 and 72 each of which slidably mate radially under respectively adjacent outmost curvilinear retaining edges of the octahedralouter edge member 46, as will be represented inFIG. 9 . - The
puzzle arrangement 20 includes anoctahedral vertex member 80, as shown by itself inFIG. 6 , that is arranged to be disposed at each vertex of theoctahedron puzzle 20, as represented inFIG. 1, 11 and 12. Theoctahedral vertex member 80 has fourtriangular face portions 82 and four side trapezoidal faces 84. The trapezoidal faces 84 are unitary with a generally square shapedfoot 86 having a curvilinear upper surface 88, as shown inFIGS. 6 and 10 . The square shapedcurvilinear foot 86 has curvilinear edges 90 which also slide radially under the outermost retaining edges 52 of the octahedralouter edge member 32 as any part of theface 22 of theoctahedron puzzle 20 is rotated about its respective rotational axis “A” going through its respective hub/bore 30 at thecore octahedral member 26. - The flattened
tetrahedral member 32 rotates on eachrespective face 28 and hub/bore 30 of thecore octahedral member 26 about a connecting pin oraxis 44 extending into the hub/bore 30 thereadjacent. The octahedralouter edge member 46 has itscurvilinear edge 60 of itsrespective foot 56 slide under the respective curvilinear retaining edges 38 of the flattenedtetrahedral member 32. The tetrahedralouter member 62 mates along side the octahedralouter edge member 46, as represented inFIG. 9 , so that itsfoot 64 engages under the outmost retainingedge 52 of the octahedralouter edge member 46. The tetrahedralouter member 62 is mated adjacent each side of theoctahedral vertex member 80, as represented inFIG. 10 , so that each respectivecurvilinear foot 64 and 90 are adjacent to one another. - An alternative embodiment of the inner core member is shown in
FIG. 13 , depicting an eight armed “spider”core member 92 with its hubs/bores 30 arranged to rotationally support radially adjacent members. Such a radially adjacenttetrahedral member 94 is shown attached to one of the hubs/bores 30, as represented inFIG. 14 - In the assembly of the
octahedral puzzle 20, two spherical boundaries as defined by the collective radially spaced apart curvilinear retaining edges 38 of the flattened tetrahedralcurvilinear member 32 and the respective radially outwardly adjacentcurvilinear edges 52 of the octahedralouter edge members 46 and its associated radially outer components to define those two spherical boundaries to provide a superior locking relationship and slidability there between of their respective components. - The
puzzle arrangement 20 may be moved by rotation “R” or “R’‘’, (as represented inFIG. 1 for example), of respective planes of components about their respective axis “A” perpendicular thereto. By such rotation of respective planes of components, the outer faces of those components may display varying colors, designs or representations.
