THREE-DIMENSIONAL LOGICAL PUZZLES
Semiregular or irregular polyhedron-based puzzles have at least two different types of faces. The dividing method used to create the puzzles requires that bisecting planes parallel to the faces be chosen to exclude at least one type of face. Preferably, the base polyhedron has a Buckyball (soccer ball) shape. Applying this dividing method to a Buckyball polyhedron results in (i) a center element with six axes passing through geometrical centers of pentagonal faces, (ii) twelve pentagonal rotating elements, and (iii) thirty mobile elements of tetrahedral shape. The mobile elements are exchangeable between adjacent groups. In another embodiment, sliding elements are superimposed over the mobile elements to enable sliding motion in addition to shifting/rotating motion. Different indicia patterns can be used to modulate the difficulty level of the puzzle. The same dividing method can be used on a sphere to obtain a completely spherical puzzle.
The present application claims priority under 35 U.S.C. 119(e) from U.S. Provisional Patent Application Ser. No. 60/896,511 filed on Mar. 23, 2007.
TECHNICAL FIELDThe present invention relates generally to three-dimensional logical puzzles and, in particular, to puzzles having either a spherical shape or a shape based on a semiregular or irregular polyhedron.
BACKGROUND OF THE INVENTIONSince the introduction of the Rubik's Cube, numerous types of shifting-movement polyhedron-shaped three-dimensional puzzles have been disclosed. These various puzzles can be classified as regular, semiregular or irregular polyhedron-shaped puzzles, a classification based on Leonhard Euler's findings that all polyhedron patterns can be broken down into three elements: (i) two-dimensional faces; (ii) one-dimensional edges; and (iii) zero-dimensional vertices.
For a polyhedron to be regular, the faces of the polyhedron must be identical and the same number of faces must meet at each vertex (called the “valence”). Polyhedrons with only one kind of vertex (congruent vertex) but two different kinds of faces are called semiregular. The remaining polyhedrons are classified as irregular. However, even irregular polyhedreons follow Euler's law that the number of vertices plus the number of faces in every polyhedron must equal the number of edges plus two.
The regular polyhedron family is surprisingly limited to only five, the tetrahedron (four triangular faces, six edges, and four tri-valent vertices), the cube (six cubic faces, twelve edges, and eight tri-valent vertices), the octahedron (eight triangular faces, twelve edges, and six quadri-valent vertices), the dodecahedron (twelve pentagonal faces, thirty edges, twenty tri-valent vertices), and the icosahedron (twenty triangular faces, thirty edges, and twelve quintus-valent vertices).
The prior art of shifting-movement puzzles includes regular, semiregular and irregular polyhedrons. Aside from ubiquitous cubic puzzles, such as the Rubik's Cube, there are numerous other types of polyhedron-based puzzles known in the art such as, for example, those based on a regular tetrahedron (e.g. U.S. Pat. No. 4,558,866 to Alford), a regular octahedron (e.g. U.S. Pat. No. 4,451,039 to Hewlett, U.S. Pat. No. 4,478,418 to Sherman, U.S. Pat. No. 4,496,155 to Goldfarb, U.S. Pat. No. 4,557,484 to Sherman-Francis, U.S. Pat. Nos. 4,593,907 and 4,706,956 to Abu-Shumays and U.S. Pat. No. 4,593,908 to Ibrahim).
Furthermore, puzzles based on a regular dodecahedron are also known in the art (e.g. U.S. Pat. No. 4,416,453 to Sasso, U.S. Pat. No. 4,506,891 to Alexander-Piaget, U.S. Pat. No. 4,558,866 to Alford, U.S. Pat. No. 4,600,199 to Krell, and U.S. Pat. No. 4,674,750 to Abu-Shumays).
Puzzles based on a regular icosahedron are described in U.S. Pat. No. 4,473,228 to Hart, U.S. Pat. No. 4,474,376 to Gustafson, U.S. Pat. No. 4,529,201 to Nadel, U.S. Pat. No. 4,575,088 to Peek, and U.S. Pat. No. 4,706,956 to Abu-Shumays.
Semiregular cuboctahedron and icosidodecahedron puzzles are described in U.S. Pat. No. 4,478,418 to Sherman and in U.S. Pat. No. 4,557,484 to Sherman-Francis.
Irregular rhombicosidodecahedron and irregular rhombic dodecahedron puzzles are described, respectively, in U.S. Pat. No. 4,529,201 to Nadel and U.S. Pat. Nos. 4,593,907 and 4,674,750 to Abu-Shumays. Furthermore, puzzles based on an irregular prism, cross, diamond, and truncated cube are described by Abu-Shumays in U.S. Pat. No. 4,593,907.
Furthermore, there exist a number of other irregular-polyhedron-type puzzles based on an irregular heptahedron (e.g. U.S. Pat. No. 4,836,549 to Flake), an irregular (so-called) hexagram (e.g. U.S. Pat. No. 5,199,711 to Pataki et al.), an irregular mix of octahedron and tetrahedron (e.g. U.S. Pat. No. 5,386,993 to Apsan), an irregular stellated icosahedron (e.g. U.S. Pat. No. 4,529,201 to Nadel), as well as other irregular polyhedrons (e.g. U.S. Pat. No. 4,500,090 to Nieto, U.S. Pat. No. 4,522,402 to Henry, U.S. Pat. No. 4,593,908 to Ibrahim, U.S. Pat. No. 4,600,199 to Krell, U.S. Pat. No. 5,722,657 to Cabrera, and U.S. Pat. No. 6,644,665 to Brooks.)
Also of interest in the prior art is U.S. Pat. No. 4,453,715 to Halpern which teaches an oblique twistable three-dimensional puzzle that uses, for example, a dodecahedron as the guiding polyhedron.
Also known in the art are three-dimensional sliding puzzles, such as the quasi Buckyball shaped sliding puzzle disclosed by Blazek and al. in U.S. Pat. No. 6,994,343.
Cubic puzzles having a combination of both sliding and shifting elements is described by Kuchimanchi in U.S. Pat. No. 4,872,682 and Pop in U.S. Pat. No. 5,116,502.
Also known in the art are ball-shaped or spherical puzzles such as the one disclosed in U.S. Pat. No. 7,108,263 to Cabeza et al. The Cabeza puzzle is a sphere dissected by three vertical planes and three horizontal planes. These orthogonal dissections of the sphere create two orthogonal pairs of hemispheres which are further subdivided to create six outer spherical sections. The hemispheres and outer spherical sections (and the layers defined therebetween) can be rotated in two orthogonal directions to enable both shifting and sliding movements.
Also known in the art are three-dimensional labyrinth puzzles, such as the one taught by Fang et al. in U.S. Pat. No. 7,165,768. In the Fang puzzle, a sphere is divided by two vertical planes and two horizontal planes to enable rotation of the resulting elements. The elements have bores formed therein, defining tunnels to enable a small ball to travel within the tunnels from an entrance to an exit.
Despite the plethora of polydredon-based puzzles and spherical puzzles that are now known in the art, to the best of Applicant's knowledge, none of the semiregular or irregular polyhedron-based puzzles known in the art enable both rotating/shifting movement in combination with sliding movement about one specific type of face. Therefore, a semiregular or irregular polyhedron-based puzzle enabling shifting (and optionally also sliding movement) would provide a highly challenging, entertaining and aesthetically-pleasing three-dimensional puzzle.
As regards spherical puzzles, to the best of Applicant's knowledge, none of the spherical puzzles known in the art are created by dividing a sphere based on a guiding polyhedron, i.e. by defining outer spherical sections by dividing the sphere parallel to a guiding polyhedron to create overlapping spherical sections on the sphere. A spherical puzzle created by this technique would be challenging, entertaining and aesthetically-pleasing.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide a challenging, entertaining and aesthetically pleasing semiregular or irregular polyhedron-based puzzle having elements that can be shifted (i.e. twisted or rotated) to enable a user of the puzzle to rearrange the movable elements of the puzzle to attempt to restore color patterns, or the like, displayed upon outer faces of the movable elements.
The present invention thus provides a three-dimensional puzzle having either a semiregular polyhedron shape or an irregular polyhedron shape, defining at least two different types of faces (or “pieces” or “elements”). For example, in a semiregular polyhedron, there would be two different types of faces, a first set of faces and a second set of faces. The first set of faces is rotationally connected to a core or center element to define a plurality of rotating elements while the second set of faces are mobile elements grouped around each rotating element, as will be elaborated below.
In accordance with another aspect of the invention, the semiregular or irregular polyhedron-shaped puzzle can further include superimposed sliding elements that slide in grooves in the underlying faces so as to provide a combination of sliding and shifting (“twisting” or rotational) movements, as a further challenge.
Another object of the present invention is to provide a challenging, entertaining and aesthetically-pleasing spherical puzzle.
Accordingly, another aspect of the present invention is a spherical puzzle having a sphere dissected into twelve overlapping outer spherical sections that are created by “slicing” (i.e. sectioning or dividing) the sphere using cutting planes that are parallel to each one of the twelve pentagonal faces of a dodecahedron. In general, this spherical puzzle includes an optional central core, such as a dodecahedron, a plurality of rotating elements rotationally connected to the optional central core, each rotating element having a convex outer face defining a portion of a sphere, a plurality of first mobile elements connected to each of the rotating elements, a plurality of second mobile elements connected to each of the rotating elements between each of the first mobile elements, whereby the rotating elements, the first mobile elements and the second mobile elements together constitute a complete sphere and wherein the rotating elements and their respective groups of first and second mobile elements together define overlapping circles on the sphere to enable interchanging of first and second mobile elements of one group with first and second mobile elements of another adjacent group.
In accordance with yet another aspect of the invention, the spherical puzzle can further include superimposed sliding elements for sliding in grooves formed in the underlying rotating and mobile elements to thus enable sliding movement in addition to shifting movement. The convexly shaped superimposed sliding elements are clustered in non-overlapping circles on the sphere to enable exchanging of sliding elements when the clusters are rotated.
Another object of the present invention is to provide a three-dimensional Buckyball or spherical puzzle that serves as an advertising medium, particularly in the realm of sports where the puzzles can be made to resemble or mimic sports balls. The outer surfaces of these puzzles can be used to display logos such as, for example, corporate logos of sponsors or sports team logos.
The embodiments of the present invention will now be described with reference to the appended drawings in which:
These drawings are not necessarily to scale, and therefore component proportions should not be inferred therefrom.
DESCRIPTION OF THE PREFERRED EMBODIMENTSBy way of introduction, four preferred embodiments will be presented in the present disclosure.
A first embodiment entails a Buckyball-shaped polyhedron having twelve pentagonal rotating elements and twenty hexagonal faces, each hexagonal face being subdivided into six triangular faces, three of these six triangular faces being part of three mobile elements while the other three of these six triangular faces being part of three rotating elements. The quasi-tetrahedron shaped mobile elements are grouped around each of the rotating elements in shifting sections of the Buckyball to thus provide a soccer-ball shaped shifting puzzle whereby mobile elements of one group can be interchanged with mobile elements of other groups.
A second embodiment also entails a Buckyball-shaped polyhedron but further includes, on each of the hexagonal faces, superimposed permutable sliding members that slide in grooves in the underlying hexagonal faces to provide both shifting and sliding movements.
A third embodiment is a shifting spherical puzzle created by dissecting a sphere with cutting planes that are parallel to each of the twelve faces of a guiding dodecahedron to generate twelve partially overlapping outer spherical sections, each centered about a respective spherical rotating element. The resulting spherical puzzle thus has twelve convexly curved pentagonal rotating elements each having five inwardly curved sides for engaging five oblong mobile elements, each having outwardly curved sides. Between each adjacent pair of the oblong mobile elements are disposed one of five triangular spherical gap elements. The five oblong mobile elements and the interspersed spherical gap elements together constitute a group of mobile elements that orbits together in unison when their respective rotating element is rotated. With the rotating element, the five oblong mobile elements and the five spherical gap elements together constitute an outer spherical section of the sphere (i.e. a convexly shaped outer portion of the sphere having a circular base plane) that overlaps with each of the five adjacent outer spherical sections associated with each of the five adjacent rotating elements. Since the mobile elements of one group are shared with adjacent groups, rotation of one group can cause mobile elements to be interchanged with mobile elements of adjacent groups.
By analogy with the first and second embodiments, the fourth embodiment builds upon the third embodiment by adding sliding movement to the pre-existing shifting movement to further complicate the puzzle. In the fourth embodiment, in addition to the shifting of each group of spherical mobile elements, the spherical rotating elements, the spherical mobile elements and the spherical gap elements are provided with grooves to enable superimposed sliding elements to slide relative to the underlying shifting spherical gap elements. The superimposed sliding elements include three quasi-oblong elements with outwardly curved sides, three quasi-triangular gap elements and a central triangular cap element that together constitute a rotatable circular cluster.

By way of partial summary thus far, and without limiting the foregoing discussion, the first and second embodiments of the present invention are based on the Buckyball-shaped polyhedron, i.e. a polyhedron that is shaped approximately like a soccer ball in which there are twelve pentagons and twenty hexagons (each hexagon being divided into six triangles).
The Buckyball polyhedron used in the first and second preferred embodiments is defined as a semiregular polyhedron, with thirty two faces, twelve pentagons and twenty hexagons, ninety edges and sixty vertices, exactly three edges emanating from each vertex (tri-valent), and all edges being of equal length.
The resulting Buckyball puzzle includes:
(i) A center element (or core) having six axes passing through the center of the puzzle and the geometrical center of every pair of opposite pentagonal faces of an imaginary, or real, central regular dodecahedron polyhedron;
(ii) Twelve rotating elements shaped generally like an angularly extruded pentagon rotationally mounted on the center element to provide a plane of rotation for these elements parallel to their pentagonal outer faces;
(iii) Thirty mobile elements shaped like opposed quasi-tetrahedrons attached to the puzzle in groups of five around each rotating element with proper guiding surfaces enabling the mobile elements to change from one group to another when the rotating elements are rotated; and
(iv) Optionally, one hundred and twenty sliding elements shaped generally like angularly extruded equilateral triangles guided and secured in coincident semi-circular retaining groves provided in both rotating and mobile elements, thus constituting hexagonal clusters of six permutable sliding elements superimposed on every hexagonal face of the puzzle.
Accordingly, the puzzle provides a plurality of rotating elements and a plurality of shiftable elements which rotate in groups and which optionally (in the second embodiment) combine superimposed sliding elements. The objective of these puzzles is to exchange or interchange mobile or sliding elements from group to group, or cluster to cluster, in order to restore the surfaces to their original pattern. The difficulty level of a single puzzle can be modulated by varying the indicia patterns situated on exposed faces of the polyhedron.
Although the first and second preferred embodiments are based on the Buckyball polyhedron, other semiregular polyhedrons could also be used as the guiding polyhedron and bisected with the same dividing method, all without departing from the scope of the present invention. Likewise, the dividing method could also be applied to irregular polyhedrons to achieve create other interesting and challenging puzzles. Accordingly, the drawings and description are to be regarded as being illustrative, not as restrictive. In other words, these embodiments can be generalized as being polyhedron-based puzzles having at least two different types of faces and to which a dividing method is applied that uses bisecting (also known as dissecting or cutting) planes that are parallel to one of the two faces, thus excluding at least one type of face (the “excluded faces”). The excluded faces are divided by the bisecting planes to generate a plurality of mobile elements while the non-bisected faces provide a plurality of rotating elements.
Different positions of the bisecting planes in respect to the base polyhedron vertices using the same proposed dividing method will result in a different quantity of elements and a different type of elements achieving either simpler or more complex puzzles. These simpler or more complex puzzles are within the scope of the invention presented in this disclosure. Various combinations, changes or modifications are possible giving almost any arbitrary exterior shape if the dividing method is used with other semiregular and irregular polyhedrons.
While the puzzle elements and parts are preferably manufactured from plastic, these puzzles can also be made of wood, metal, or a combination of the aforementioned materials. These elements and parts may be solid or hollow. The motion of the puzzle mechanism can be enhanced by employing springs, bearings, semi-spherical surface knobs, grooves, indentations and recesses, as is well known in the art and are already well described in the prior art of shifting and sliding puzzles. Likewise, “stabilizing” parts can also be inserted in the mechanism to bias the moving elements to the “rest positions”, as is also well known in the art.

As mentioned above, the spherical puzzles of the third and fourth embodiment can also be constructed without a core or center element 10. While it is preferable to utilize a core or center element 10, it is also possible to construct the spherical puzzles of the third and fourth embodiment without any core or center element 10. A coreless spherical puzzle can be constructed by providing the spherical rotating elements 120, spherical mobile elements 130 and spherical gap elements 180 with appropriate protrusions and grooves. These protrusions and grooves cooperate as interfitting male and female connections to slideably and rotatably interlock the various elements to thus hold the elements together to form a complete sphere. Since the spherical rotating elements 120, spherical mobile elements 130 and spherical gap elements 180 are interlocked, there is no longer any need for a center element 10 or core to retain or hold the various elements of the spherical puzzle in place. For example, in one implementation of this coreless spherical puzzle, each spherical rotating element 120 would have grooves (or female connectors) on each of its five inwardly curved sides. To interlock with each spherical rotating element 120, each spherical mobile element 130 would have protrusions (male connectors) on its two outwardly curved sides with grooves (female connectors) on its two inwardly curved sides. To interlock with both the spherical rotating elements 120 and the “female sides” of the spherical mobile elements 130, each of the spherical gap elements 180 would have protrusions (or male connectors) on each of its three sides.
The same techniques for arranging the display of colours, emblems, logos or other visual indicia on the outer surfaces of the puzzles to modulate the difficulty level (as was described with regard to
The visual indicia could be made of distinctive colours, textures, visible legends (numbers, letters, symbols, images, or a combination) or a combination of the above, or patterns of the above, or corporate and/or team logos, or emblems, or national flags applied on the visible portions of the puzzle. The outer shell of the puzzles can be used to mimic objects such as a soccer ball, basketball, baseball or the like. The outer shell could reproduce cartoons, heads and/or faces, organs, planets and the like. The outer shell could be used for learning purposes, publicity and marketing purposes, artistic purposes and other applications as well.
In a variant, some or all of the hexagonal faces can be made pyramidal, i.e. the geometrical centers of the hexagonal faces can be stellated. The resulting stellated puzzle would have a spiky appearance.
It will be noted that exact dimensions are not provided in the present description since these puzzles can be constructed in a variety of sizes.
The foregoing puzzles are symmetrical, aesthetically-pleasing, entertaining and challenging. Although the theoretical number of permutations is enormous, especially for the second and fourth embodiments, the difficulty level of these puzzles can be easily modulated by reducing the number of different visual indicia (e.g. color schemes or face patterns) that are displayed on the faces. In other words, different versions of the puzzle can be provided for novice, intermediate or expert players, or even for kids.
Three-Dimensional Puzzles Having Outer Element Surfaces Displaying Corporate and/or Team Logos
Another aspect of the present invention is a three-dimensional puzzle that serves as an advertising medium. In other words, this three-dimensional logical puzzle includes a plurality of moving elements having outer surfaces upon which can be displayed one or more logos such as, for example, corporate logos or sports team logos.
The puzzle is preferably either a Buckyball-shaped puzzle or a spherical puzzle, but other shapes could be used for displaying corporate or team logos. For example, since the Buckyball approximately resembles a soccer ball, the Buckyball-shaped puzzle is ideally suited as a promotional item in the world of soccer. For example, since the Buckyball-shaped puzzle has 32 faces (12 pentagons and 20 hexagons), the Buckyball puzzle would be ideally suited to display the national soccer team logo of each of the 32 nations in the FIFA World Cup Soccer Tournament. Of course, the puzzle can be used to display team logos for other tournaments or leagues having fewer than 32 teams (by simply leaving some surfaces blank or by using one or more of these “spare” surfaces to identify the league or authority (e.g. FIFA, UEFA, English Premier League) or to identify the host country, year of the tournament, etc.)
Again by way of example only, the faces of the Buckyball could also display corporate logos of sponsors of a tournament or event. For example, the logos of each of the corporate sponsors (Yahoo®, Coca-Cola®, Mastercard®, etc.) of the FIFA World Cup tournament could be displayed on each of the outer faces of the Buckyball puzzle. Alternatively, the puzzle could display a mix of team and corporate logos. Alternatively, only a subset of the outer faces of the puzzle could display logos, with the other surfaces being blank or solid coloured (i.e. to reduce the difficulty level of the puzzle, e.g. for kids).
As other examples, all or a subset of the faces of the Buckyball puzzle could be used to display team logos for the various teams of national soccer leagues, such as the English Premier Division, the Italian Serie A, the German Bundesliga, etc. As further examples, the Buckyball puzzle could display player jerseys (with player names and/or numbers), player faces, league emblems, etc. In addition to the Buckyball puzzle, the spherical puzzle is also ideally suited for corporate advertising or team logos in the world of soccer due to its close resemblance to a soccer ball.
Using the puzzles for advertising or displaying team or corporate logos can of course be utilized in other sports, including, but not limited to, basketball, baseball, tennis, golf, volleyball, handball, water polo, etc. where the puzzle can be made to mimic the look of the actual ball, for example, by drawing or printing suitable seams, lines, dimples, etc. on the outer surfaces of the puzzle to create a replica of the actual ball. For example, a puzzle made to look like a baseball could have seams drawn over the outer surfaces, with major league team logos or emblems on each of the outer surfaces, or on a subset of the outer surfaces.
Although the spherical puzzle is best suited for producing replica balls for sports having round balls, the same concept can be applied to sports that do not involve balls, or to sports having differently shaped balls (regardless whether the shape of the puzzle matches the shape of the actual ball used) such as, for example, for hockey, football, rugby, boxing, motor sports, etc.
In the foregoing examples, it should be noted that the difficulty-level of the puzzles could be modulated by displaying fewer logos on the puzzle, with some faces being solid colours or blank (white) for example, or by displaying logos that cover more than one of the outer surfaces of the puzzle. A very simple Buckyball or spherical puzzle would thus have two solid coloured hemispheres. By analogy, a logo puzzle having only two large logos, one on each of the hemispheres, would be fairly easy to solve. Alternatively, a single corporate sponsor could advertise exclusively on a spherical puzzle or Buckyball puzzle by having multiple instances of their emblem, for example, interspersed with solid colours (or white surfaces), or alternatively, have a single corporate emblem or logo printed on the entire outer surface such that it is effectively “wrapped around” the entire sphere or Buckyball.
Thus, it should be apparent that the logos need not be confined to each hexagonal or pentagonal surface of the Buckyball, e.g. a logo could be displayed over two or more contiguous outer faces. In the case of the spherical puzzle, the logos or other visual indicia could be printed without discretely confining the displays to each cluster of elements. Thus, for example, one could also produce a spherical puzzle having a map, stylized map or satellite photo of Planet Earth, of the moon, or of another planet, of a head of a person (historical, celebrity, famous or otherwise), or any other pattern of colors, artwork, photo, etc. that would provide an interesting visual puzzle.
In another example, a spherical or Buckyball puzzle could have alternating black and white faces like a traditional soccer ball but upon which a small number of logos would be displayed. Again, the difficulty level of the puzzle can be modulated by changing the number and size of the logos. A replica of the official ball of the FIFA World Cup or of a particular team or league or tournament or event could be created. For example, for fans of the Azzurri, a puzzle replicating a blue soccer ball with the colours and emblems of the Italian national soccer team could be produced, e.g. with the red, white and green Italian flag placed on one or more faces of the ball. For example, for fans of Manchester United, a puzzle replicating a red ball could be produced with the team emblem on one or more faces.
The puzzle with logos would provide not only a useful advertising medium for corporate sponsors, but also serve as entertainment for fans before the game, during half-time, or afterwards. In addition to being a challenging and fun toy, the puzzle displaying team logos, player jerseys, player faces, etc. would also serve as a lasting souvenir or memento of a particular tournament for fans to cherish for many years afterwards, while providing highly valuable, ongoing advertising for corporate sponsors, particularly for those puzzles that display a mix of team and corporate logos, for example, the emblems of the two finalists of a major tournament or league plus the corporate names/logos of the tournament's primary sponsors.
Although the preferred embodiments are the Buckyball puzzle and the spherical puzzle, it should be noted that advertising, corporate logos or team logos could also be placed onto the surfaces of other types of three dimensional puzzles to create promotional vehicles or souvenirs.
It is understood that the above description of the preferred embodiments is not intended to limit the scope of the present invention, which is defined solely by the appended claims.
