Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to puzzles. In particular to three dimensional jigsaw puzzles. 
       BACKGROUND 
       [0002]    Jigsaw puzzles are popular pastimes with young and old. They exercise the mental faculties and may have therapeutic and/or educational value. 
         [0003]    Traditional jigsaws are created by cutting up two dimensional pictures into pieces. Complexity is added by having more and more pieces. However, jigsaws consisting of large number of pieces require large areas and tend to occupy the table top or work surface for extended periods. If the assembled jigsaw shows an interesting picture, there is little extra complexity involved in jigsaws having large numbers of pieces as the user initially sorts out the pieces into groups, breaking down the task into manageable components. Thus where a landscape picture is cut up into a jigsaw puzzle, the user will sort out the pieces into sky, grass, trees etc. 
         [0004]    To add a further dimension to puzzles, three dimensional puzzles have been created. 
         [0005]    U.S. Pat. No. 2,327,718 to Kassler and U.S. Pat. No. 2,399,599 to Owen disclose children&#39;s toys having stackable pieces but which do not involve piece sequencing. Many other issued patents also disclose a multi-piece toy, and different types and degrees of pattern recognition and pattern matching are involved. 
         [0006]    U.S. Pat. No. 2,493,697 to Raczkowski describes a profile building puzzle comprising a plurality of layers wherein each layer slides over a central post. The individual layers may be puzzles themselves, comprising a plurality of pieces. However, the pieces in each layer do not individually engage the post. 
         [0007]    U.S. Pat. No. 3,981,506 to Wayne and Brian describes a three dimensional relief that consists of a plurality of parallelepiped blocks having varying heights, planar sides and a curved upper surface, that are connected together by special pin and hole interlocks randomly spaced in predetermined locations to form a three dimensional puzzle with at least a curved upper surface. Two or more puzzles can be made by initially assembling the blocks into a polyhedron with six rectangular faces and sawing along a predetermined path to separate the polyhedron into individual puzzles. Complex shaped objects may be assembled from the pieces, but the puzzle is not a stacking puzzle having a central core. 
         [0008]    U.S. Pat. No. 3,856,308 to Breslow and Dunn describes a Three Dimensional Game Apparatus comprising, in combination, an upright hollow column resembling an elevator shaft having indicia therealong representing a plurality of floors along the elevator shaft. There is a slot in the column at each floor. A plurality of playing pieces are positionable into said upright column, through the slots, each playing piece having indicia thereon correlated to at least one of said floors. A plunger is vertically movably mounted on said upright column and has a simulated elevator thereon for alignment with said floors. A plurality of instruction cards direct movement of the simulated elevator within the column. Transparent strips set in the column permit viewing of the position of the simulated elevator. 
         [0009]    U.S. Pat. No. 4,259,804 to Samuels provides a toy with stackable facial-expression puzzles, and although its use helps develop pattern recognition and pattern matching skills, there is no requirement for particular pattern sequencing. U.S. Pat. No. 4,356,659 to Clarke teaches a take-apart doll that comprises a stackable three-dimension toy. 
         [0010]    U.S. Pat. No. 5,104,345 to Lyman discloses a multi-piece toy that can be stacked in a three-dimension configuration. 
         [0011]    U.S. Pat. No. 5,810,357 to Brink describes a stackable three dimensional toy for spatial learning for children that comprises molded cores having adjacent zones configured to correspond to unitary planar shape members that stack in predetermined sequence. 
         [0012]    U.S. Pat. No. 5,165,689 to Forsse and Forsse describes a three-dimensional jigsaw puzzle sculpture, that includes a frame which defines the shape of the sculpture, and a puzzle assembled to the frame. The frame has a three-dimensional configuration and includes a channel extending around the periphery of each frame section to hold the puzzle pieces in place. Each frame section provides a substantially planar surface circumscribed by a channel, which planar surface provides a support for the puzzle pieces. The planar surfaces include one or more apertures which are utilized to remove the puzzle pieces from the frame. Separable frame members are assembled to one another utilizing pin and hole interlocks. The three-dimensional jigsaw puzzle sculpture, when fully assembled, provides a decorative piece of art which may be subsequently disassembled and reassembled as desired. In this development, flat traditional two dimensional jigsaw pieces are assembled onto a three dimensional former. 
         [0013]    U.S. Pat. No. 5,683,086 to Druckman and Hershkowits describes a sculpture puzzle which includes a base and a core which is attached to, and extends from, the base. The sculpture puzzle is constructed by sequentially mounting a number of planar segments to form a three dimensional figure. 
         [0014]    U.S. Pat. No. 5,806,853 also to Druckman and Hershkowits describes a further sculpture puzzle which includes a base and a core which is attached to, and extends from, the base. The sculpture puzzle is constructed by sequentially mounting a number of planar segments to form a three dimensional figure. Here each layer simply slides over the core. In one embodiment, shown in  FIG. 9  thereof, one or more layers may comprise two pieces that fit together around the core. To assemble the puzzle, the layers must be stacked from the base upwards. 
         [0015]    U.S. Pat. No. 6,276,684 to Druckman, Hershkowits and Kishon also relates to a puzzle comprising a plurality of planar elements and a main core member. When the plurality of planar elements are assembled in a correct order then the planar elements together define a recognizable three-dimensional figure. In some aspects of the invention the planar elements comprise at least first and second sub-groups of planar elements. The first sub-group of planar elements are for assembly on the main core member. The assembled three-dimensional figure comprises a plurality of separately identifiable components. One of the components is defined totally by the second sub-group of planar elements and is an entity identifiable separately from the remainder of the assembled puzzle. In some embodiments the planar elements of the second sub-group are mounted on a branch core member. The planar elements of the second sub-group can be mounted on a branch core member so that they are not parallel to the planar elements of the first sub-group. 
         [0016]    European Patent Application Number EP0877645A1 describes a puzzle toy which, when assembled, forms a three-dimensional figure or statue etc. Once again, this has core member and number of planar elements which are sequentially mounted on core member to form the figure. 
         [0017]    U.S. Pat. No. 5,700,177 to Lemelson describes yet another stacked components assembly toy, for constructing a three-dimensional composite object as defined by the successive edges of a plurality of planar members stacked upon one another in a particular order. An axial structure such as a pair of rods is mounted to a base structure and passes through holes of each of the stacked members to align the holes of each such member and thereby fix its position and orientation. The toy may be provided as a puzzle with the user left to discover the particular order of stacking which results in the predetermined composite object, or each member may be labeled to indicate its stacking order. 
         [0018]    United Kingdom Publication Number GB2357705A describes a three-dimensional sliding puzzle that involves the ordering of movable pieces until a recognizable or pre-defined, external pattern is successfully completed. The three-dimensional puzzle comprises a tracked inner core and a number of movable connected external pieces that have a recognizable display of colours, icons and/or patterns on the external surface of the moving pieces. The puzzle may be of a hand held size, and the movement of the external pieces may be facilitated by a system of grooved tracks into which the external pieces are connected by a protruding stem whose end can be fashioned so that it fits into the grooved tracks on the inner core, allowing the external moving pieces to be permanently attached yet capable of moving around the inner core. The external movable pieces can be moved around the grooved tracks of the inner core to allow the correct alignment of the colours and or patterns on the external surface. The course of the grooved tracks ( FIG. 5 ,  9 ) over the inner core may be altered so that the difficulty of the puzzle can be increased or decreased. Here the puzzle is one of sliding pieces around a frame to produce an image, rather than a construction puzzle for assembling separate pieces. 
         [0019]    U.S. Pat. No. 4,513,970 to Opresco et al. describes a three dimensional amusement puzzle having eight outer bodies rotatably connected via magnets to a spherical core. This Polymorphic twist puzzle has eight outer bodies or blocks that may be rotated, four at a time, about any one of three axes, so that different shapes may be presented in different combinations of said outer bodies. The outer bodies present a desired shape, such as an egg, sphere, clown&#39;s head or other desired shape only when the outer bodies are in proper combination. The outer bodies revolve about a spherical core, and are releasably maintained assembled about said core by magnetic means on the adjoining surfaces of the outer bodies. 
         [0020]    World Publication Number WO2002/07835 to Song et al. describes a cubic puzzle structure for developing an intellectual faculty of infants or children through assembling puzzles or games in a three dimensional space. A cubic body is laterally cut into a lot of slices and each hole is formed at the center of each slice to be aligned with a long z-axis on the sustaining board. These slices can be stacked one by one through the hole and z-axis on the sustaining board, finally reaching the original complete unit. In addition, drawings or character letters are printed on the surface of cubic body or slices to enhance one&#39;s imagination or help assembling. In addition, the number of z-axis can be easily extended into more than one z-axis to add more interests or increase level of difficulty, where each slice is segmented again into smaller sectors which forms a separate unit of puzzle on every level of slice. Here, each piece has a hole therethrough for threading over a peg in turn. Optionally a number fo parralel pegs are provided, and each slice comprises a plurality of pieces that each slide over one of the pegs. The puzzle must be assembled from the base upwards, one layer at a time by threading over the pegs. 
         [0021]    U.S. Pat. No. 6,234,858 to Nix describes deformable foam toys and puzzles wherein novel resilient foam puzzles can be removed from puzzle form and converted into a three dimensional objects, such as toy foam animals. The objects preferably include interchangeable parts, and more preferably include articulating appendages which are interchangeably attachable to a body portion at pivot structures that are affixed to, or which extend thru, the body portions. Preferably, pivot structures are formed by resilient foam pivot pins having deformable retaining caps at opposing ends thereof, which, in the case of foam animals, serve to retain articulating limbs. Alternately, a hex-shaped socket aperture defined by a wall edge portion is provided as a joint socket in one or more of the limbs, and a parallepiped, and preferably an elongated rectangular shoulder pin or hip pin is provided for displaceable frictional engagement with the hex shaped socket to articulate the limbs to desired positions. In animal form, such foam articles provide an interesting, attention focusing toy for children. Various designs can be used to increase the variety of shapes, sizes, and colors. The toys can be made in the shape and size appropriate to suggest any desired objects or animal species. The design provides an interesting novel structure for assembling toy animals. 
         [0022]    United Kingdom Publication Number UK 2,333,717 describes yet another stacking puzzle. 
         [0023]    U.S. Pat. No. 6,655,685 to Tsai describes yet another three dimensional jigsaw puzzle. Here, the three-dimensional jigsaw puzzle includes a three-dimensional core body having a vertical axis and including a plurality of stackable block units formed by cutting the core body along a plurality of transverse cutting planes that are transverse to the vertical axis. Each of the block units has top and bottom surfaces which are opposite to each other in a vertical direction that is parallel to the vertical axis, and includes at least two block members formed by cutting each of the stackable block units along at least one vertical cutting plane that is parallel to and that passes through the vertical axis. A plurality of interlocking members are disposed to interlock removably an adjacent pair of the block units. Essentially, each piece has a peg protruding therefrom which engages a corresponding socket in adjacent pieces. The central pole is dispensed with and one can start assembly from any position, building upwards or downwards. Each piece is attached to its neighbours. 
         [0024]    World Publication Number WO2004/039465 to Bouchard et al. describes a puzzle device having a shaft member and a number of adjacent like wheels rotatably mounted onto the shaft member. A number of tiles are distributed over peripheral surfaces of the wheels and slideably mounted on them for lateral sliding from one of the wheels to an adjacent wheel provided that the adjacent wheel has a space adapted to slideably receive the tile and that the tile is properly aligned with the space. The tiles bear indicia determining desired final puzzle positions over the cylindrical puzzle surface defined by the peripheral surfaces of the wheels. Pin and slot arrangements interconnect the wheels for communicating rotation from one of the wheels to all immediately adjacent wheels whenever the concerned wheel is rotated past a specific rotation angle. This type of puzzle is not a jigsaw type puzzle of seperable pieces at all. 
         [0025]    World Publication Number WO2004/0123500 to Lau relates to a three-dimensional puzzle hanging ornament comprising a ring, a bolt, a hanging ornament body and a layer of puzzle pieces. The hanging ornament body is three-dimensional in shape and has a round opening with screw threads inside. The front end of the bolt has screw threads. The surface of the front end of the bolt is made of magnet. The surface of the hanging ornament body, onto which the puzzle pieces are attached, is magnetic. The present invention is portable, with pieces not easily fallen off and is convenient to play with. As the present invention is three-dimensional in shape, it has higher entertainment and aesthetic value than conventional two-dimensional puzzles. The present invention can serve as a dual-purpose entertainment and ornamental object, the appearance of which is attractive and decorative. This is in contrast to conventional puzzles, which only serve a single gaming purpose. Here the pieces are essentially a three dimensional shell, such as the outer layer of a ball that has been cut into two dimensional jigsaw puzzle piece. These fit onto a magnetic core that holds the pieces in place. 
         [0026]    Japanese Publication Number JP 07155460A2 describes a three dimensional jigsaw puzzle of iron and on which press molding and painting processing are performed, on a core material composed of a magnet. 
         [0027]    United States Published Application Number US20030168804A1 describes a three-dimensional puzzle that includes a three-dimensional core body having a vertical axis and including a plurality of stackable block units formed by cutting the core body along a plurality of transverse cutting planes that are transverse to the vertical axis. Each of the block units has top and bottom surfaces which are opposite to each other in a vertical direction that is parallel to the vertical axis, and includes at least two block members formed by cutting each of the stackable block units along at least one vertical cutting plane that is parallel to and that passes through the vertical axis. A plurality of interlocking members are disposed to interlock removably an adjacent pair of the block units. 
         [0028]    Despite the developments described above and the many patents in this crowded field there is still a demand for further puzzles that are challenging and fun, and the present invention addresses this need.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0055]    The present invention relates to three dimensional puzzles that may be assembled from separable pieces. There are many such puzzles in the prior art, however, the present invention differs from those known to the inventors in that each piece is separately attachable to a former or core, and individually engages the former or core, such that the position and orientation of the piece with respect to the former or core is fixed, regardless of whether neighbouring pieces are in position or otherwise. 
         [0056]    By way of example, with reference to  FIGS. 1 ,  2  and  3 , a car puzzle  10  is shown. The car puzzle  10  is assembled around a former  12  from a plurality of pieces  14 A- 14 N. The former  12  fits onto a support  16  that is connected to a base  18 , such that, with particular reference to  FIG. 3 , former  12  is free to rotate around support  16 , allowing puzzle to be tilted or rotated. 
         [0057]    With reference to  FIG. 3 , in one embodiment, former  12  comprises a plurality of slats  12 A- 12 I that run along axis X-X of the former  12  and extend radially from the hub  20  ( FIG. 2 ) that slips over the support  16 . Each piece  14   n  has a slit Sn therealong which can slip over and engage one of the slats  12 A- 12 I. Thus piece  14 J has a slit Sj that slots onto slat  12 A of former  12 . By constructing pieces  14 A- 14   n  from a resilient material such as polystyrene or polypropylene, the slot Sn of each piece  14   n  can be pressed onto a slat  12 A- 12   n  and will engagingly grip same. In this manner, the individual pieces  14 A- 14   n  can be indivually positioned or repositioned in any position on former  12 . 
         [0058]    With reference to  FIG. 4 , each piece  114   n  may be wedge shaped, the former  112  may comprise eight elongated slats  112 A- 112 H that radiate from a central hub  120 , so for example, slot S 114  may engagingly clip onto slat  112 A and piece  114 A will thereby engage slat  112 A and be held to hub  120  thereby. 
         [0059]    The number of slats may vary considerably between embodiments, depending on the complexity of the puzzle and the degree of intended difficulty of its assemblage. In  FIG. 5  for example, four such slats  312 A- 312 D are provided, and each layer of the puzzle will include only four pieces  314 A- 314 D. 
         [0060]    As shown in  FIG. 6 , in another embodiment, the former  520  comprises a plurality of parrallel wires or rods  412 A- 412 H. The slat in each piece  414 A- 414 H clips over the rod in the same way as it clips over the slats in previos embodiments, mutatis mutandis. 
         [0061]    With reference to  FIG. 7 , the former  620  may comprise metallic slats, and the pieces  614 A- 614 D may slip between the slats and be held in place by magnetic inserts  630 . In other embodiments, the pieces could have ferrous inserts, and the former could be magnetic, or, indeed both former and inserts could be magnetic, of opposing polarities. 
         [0062]    Referring to  FIG. 8 , magnetic inserts  670  set in the blunted inner corner of a wedged shaped pieces  660 A-D may be utilized with a polygonal former  650 , in this case, four such wedge shaped pieces may magnetically engage sides  651 A-D of a square poygonal former  650 . As described hereinabove, with reference to  FIG. 7 , mutatis mutandis, in other embodiments, the former  650  might be magnetic and the wedge shaped pieces  660  might be ferrously attracted to the magnetic former, or both former  650  and inserts  670  might be oppositely poled magnets. Obviously, the former may be magnetic. 
         [0063]    With reference to  FIG. 9 , in yet another embodiment, the former once again comprises a plurality of paralel rods or wires  820 , and the internal sides  814 A- 814 N of each wedge shaped piece  826  have notches  830  for aiding their wedging between the rods or wires, each wire/rod  820  may engage pieces on each side, along its length, or, as shown in  FIG. 10 , in a further embodiment that is a variation of this system, the rods  822  may be arranged in pairs  822 A-B,  823 A-B,  524 A-B,  825 A-B each pair  822 A-B only engaging one piece  827  in each layer. In both cases the pieces  826 ,  827 , may, if correctly oriented, simply clicking into place between the rod/wires. 
         [0064]    With reference to  FIG. 11 , in yet another embodiment, the former  1020  may comprises a rod having a plurality of disks  1030  therearound that are substantially perpendicular thereto. Each piece  1014  in each layer may slip onto one of these disks  1030 . A slit  1040  in the piece  1014  wedgably engaging the disk. 
         [0065]    There are thus several locking means by which each of the pieces may individually lock onto a former to retain a spatial relationship therewith. 
         [0066]    Although, as illustrated in  FIG. 2 , the pieces of the puzzle may be fairly chunky for assembling by a child, and will typically be fabricated from expanded polypropylene foam or the like, in other embodiments, the pieces may be die cast from metal to produce a small, high quality executive toy, for example. 
         [0067]    As shown in the embodiment of  FIGS. 1 to 3 , the former may be configured parralel to a base and the puzzle may be assembled around a horizontal axis, or as shown in  FIG. 12 , the former  1120  may be configured perpendicular to the base and the puzzle may be assembled around a vertical axis. Indeed, as shown in  FIG. 13 , in other embodiments the former  1220  may be angled to the base at any other angle, between the horizontal and the vertical. 
         [0068]    The assembled puzzle may have 2 or more pieces per layer. The layers may have two parralel surfaces that are perpendicular to the former, or may not be parralel. The assembled puzzle may produce a very wide range of characters or objects. 
         [0069]    Preferably, the former may be rotated around its axis, but this is not necessarily so. 
         [0070]    The puzzle may, when assembled, resemble any recognizable entity, such as a common object, a representation of a cartoon character, a likenesse of a bust of a person, such as a famous person, a stereotype or an animal.
