  • FIG. 9 is a partial plan view of exemplary puzzle frame pieces (PFP) having internal elements that utilize shaped protrusions (SP), interconnected object pieces (OP) and traditional jigsaw pieces.
  • the puzzle of the present invention is more easily assembled than a traditional puzzle, is able to be completed by multiple puzzlers with different skill levels at the same time and employs new mechanisms of puzzle construction. Using these new mechanisms, as discussed in detail below, the puzzles of the present invention possess the following characteristics: (1) heterogeneous skill levels; (2) clearly demarcated subdivisions, and (3) novelty and excitement.
  • Heterogeneous skill levels provides several benefits to a puzzle. It allows an entire family with different aged children to strive towards a common family goal while interacting socially. Nursing homes or mental health institutions can use such a puzzle to entertain and provide therapeutic benefits to patients of different mental and dexterity abilities.
  • the puzzle of the present invention comprises three new mechanisms of puzzle construction: shaped protrusions (SP), interconnected object pieces (OP) and puzzle frame pieces (PFP).
  • the puzzle of the present invention is referenced at 20 .
  • FIGS. 1 - 2 depict an example of a complete puzzle utilizing two of the new mechanisms: shaped protrusions (SP) and puzzle frame pieces (PFP).
  • FIG. 3 depicts a second example of puzzle pieces (not a complete puzzle) utilizing these three new mechanisms.
  • FIG. 4 depicts a third example of puzzle pieces (also not a complete puzzle) utilizing shaped protrusions and interconnected object pieces.
  • FIGS. 3 - 9 depict exemplary puzzle pieces that utilize these three mechanisms and which form the pieces of an overall puzzle, such as those shown in FIGS. 1 - 2 .
  • shaped protrusions The first new mechanism of puzzle construction is referred to as shaped protrusions, SP.
  • SP Traditionally, jigsaw puzzles have interconnected protrusions consisting of a neck and an ovoid/circular head and a receiving recess of complimentary shape.
  • SP pieces have protrusions, or recesses, which have recognizable shapes.
  • shaped protrusion/recess SP 1 are stars; in FIG. 3, shaped protrusion/recess SP 2 are fire axes, shaped protrusion/recess SP 3 are pike poles, shaped protrusion/recess SP 6 are ladders; in FIG.
  • shaped protrusion/recess SP 4 are lobster claws and shaped protrusion/recess SP 5 are fish tails.
  • the shaped protrusions SP may be in the form of a recognizable object (e.g., a fire axe, a pike pole, a lobster claw, etc.), or a recognizable geometric shape (e.g., a star, etc.).
  • shaped protrusions SP 1 SP 6 are by way of example only and are not limited to those shown.
  • the shape of the protrusions in a puzzle may also have a common theme; for example, the protrusions of the puzzle pieces of FIG.
  • FIGS. 1 - 2 have a common theme of “fire.” And, although not shown, when all of these puzzle pieces are assembled, a recognizable image (e.g., the rainbow, cloud, sun, etc. as shown in FIGS. 1 - 2 ) is formed related to fire, e.g., a fireman's hat, a fire engine, etc.
  • a recognizable image e.g., the rainbow, cloud, sun, etc. as shown in FIGS. 1 - 2
  • fire e.g., a fireman's hat, a fire engine, etc.
  • shape as used throughout this Specification includes both geometric shapes (e.g., rectangles, stars, etc.) and object shapes (e.g., animals, instruments such as axes, pike poles, ladders, fish tails, lobster claws, etc.). It should also be understood that where the phrase “shaped protrusion SP” is used, this covers both the actual protrusion and its corresponding recess in the adjacent puzzle piece that it connects with.
  • shaped protrusions SP can facilitate heterogeneous skill levels.
  • the first is by having some pieces in the puzzle be of traditional jigsaw shape while others have the shaped protrusion SP. Interconnecting the pieces using shaped protrusions is much simpler than traditional jigsaw puzzle assembly.
  • Another way is to have the shaped protrusions SP of different sizes extending from a single puzzle piece. For example, in puzzle piece 22 of FIG. 4 the shaped protrusions SP 4 ′ and SP 4 ′′ (as well as their corresponding recesses in puzzle piece 24 ) are of different sizes.
  • Pat. No. 4,625,969 (Donnell) there are significant differences in the present invention 20 .
  • the puzzle pieces of the Donnell patent are traditional jigsaw shaped pieces.
  • the Donnell patent discloses a series of graduated puzzle pieces that decrease in size, for example, beginning from the periphery of the puzzle extending toward the center.
  • multiple sizes of the shaped protrusions SP can be used to create heterogeneous skill levels; this means that a puzzle piece may contain various sized shaped protrusions SP to interconnect with adjacent pieces that have complimentary various sized recesses (FIG. 3).
  • puzzle piece 26 has a fire axe protrusion, two pike pole protrusions and one pike pole recess. It can be appreciated that by having both the fire axe and pike pole as protrusions on a puzzle piece, or by having a puzzle piece with different sizes of the same shaped protrusion SP, the number of possible locations that that piece might fit into is decreased, thus making that area of the puzzle that much easier to solve.
  • shaped protrusions SP can involve a wide variety of skill levels is where a very young child, or mentally-challenged adult, can help to find the pieces with a specific shaped protrusion SP, while more skilled puzzlers can place the actual puzzle pieces.
  • the mechanism of shaped protrusions SP can also demarcate a large puzzle into smaller subdivisions by various techniques that are now described.
  • this feature automatically identifies a puzzle piece as either belonging to a shape-A protrusion zone or a shape-B protrusion zone.
  • the shape-A protrusion zone 23 (FIG. 4) is characterized by puzzle pieces having the fish tail protrusions/recesses while the shape-B protrusion zone 25 is characterized by puzzle pieces having the lobster claw protrusions/recesses.
  • demarcation zone 27 pieces i.e., puzzle pieces with both shape-A and shape-B protrusions and/or recesses.
  • demarcation zone 27 pieces i.e., puzzle pieces with both shape-A and shape-B protrusions and/or recesses.
  • three subdivisions are created: a shape-A protrusion zone 23 , a shape-B protrusion zone 25 and a demarcation zone 27 . Therefore, for example, if a puzzle of the present invention 20 has three different shaped protrusion zones, there will exist six subdivision zones: shape-A protrusion zone, shape-B protrusion zone, shape-C protrusion zone, demarcation zone shape-A/shape B, demarcation zone shape-A/shape C and demarcation zone shape-B/shape-C.
  • the size of the shaped protrusions SP may effect heterogeneity of skill level.
  • the size of the shaped protrusions SP can also create subdivisions clearly demarcated from one another.
  • the puzzle pieces can readily be identified as belonging to one or the other zone.
  • the shape-A/size 1 protrusion zone 31 may comprise the fish tail protrusion puzzle pieces having a first size
  • the shape-A/size 2 protrusion zone 33 may comprise the fish tail protrusion puzzle pieces having a smaller second size.
  • the shaped protrusion SP size is the shaped protrusion SP size and not the size of the puzzle piece itself that forms the basis for where the piece belongs.
  • the pieces of the Donnell patent use a piece-size gradation technique where the zones gradually change in size from very large on the outside to very small on the inside of a circular puzzle and from very large on the one side to very small on the other side of a rectangular puzzle.
  • the shaped protrusion size differences are not gradual but rather are of clearly distinct size disparity, thereby allowing a user to distinctly place a piece in a particular zone with clear demarcation between the zones.
  • shaped protrusions SP introduces novelty and excitement into puzzle assembly because more than just the picture/image (e.g., the rainbow, clouds, sun, etc.) is used in the piece placement.
  • Assembling the puzzle of the present invention 20 can be educational by having shaped protrusions SP which can be used as learning tools. For example, using shaped protrusions SP such as triangles, rectangles, squares, etc., children can be asked to find pieces having one or more of these shaped protrusions SP.
  • Another aspect of the present invention 20 is that the invention can be used as a game.
  • individual players instead of having individual players each have their own jigsaw puzzle to assemble in the shortest amount of time (such as that disclosed in the Watkins patent), individual players can be assigned a respective portion or subdivision of the common puzzle of the present invention 20 to assemble in the shortest amount of time.
  • the second new mechanism of puzzle construction is interconnected object pieces OP.
  • the interconnected object pieces OP differ from those puzzle pieces disclosed in the Ordway patent and the puzzle pieces disclosed in U.S. Pat. No. 3,575,418 (Palmer).
  • puzzle pieces are scattered throughout a puzzle which can individually be recognized as an object.
  • the Palmer patent a puzzle game is disclosed where circumferential pieces need to be placed in the correct position in order to form an inner periphery where an identifiable object puzzle piece can then be placed.
  • the interconnected object pieces OP e.g., see FIG. 4, OP 1
  • the present invention 20 differ from these other patented puzzles in that the object pieces OP are used as the primary mechanism of puzzle construction.
  • each object piece OP 1 abuts, or interconnects with, multiple other object pieces OP 1 , as shown in FIG. 4.
  • These interconnected object pieces may be identical in size and shape, for example, as shown by OP 1 in FIG. 4, or by OP 4 in FIG. 6; these interconnected object pieces OP may be very similar in size and shape as shown by OP 2 in FIG. 4; or they may be vastly divergent in size, but readily identifiable as the same object as shown by OP 7 and OP 8 in FIG. 7.
  • a puzzle may also be constructed using interconnected object pieces OP readily identifiable as different objects but all having a common theme, such as the interconnected forks OP 5 and knives OP 6 shown in FIG. 8. These object pieces OP interface, or interconnect, with multiple other object pieces OP of a similar theme to comprise the puzzle or a zone of the puzzle.
  • irregular pieces IP may be logistically required to complete the puzzle. These, however, comprise a very small portion of the area of the puzzle where object pieces OP are used as the mechanism of construction; in FIG. 4, there is shown an example of such an irregular piece IP.
  • object pieces OP can create heterogeneity of skill levels are multiple.
  • the very young can simply pick out recognizable objects while the more skilled puzzlers can place them.
  • a puzzle may have one zone of object pieces OP that are inherently more challenging to place than another zone.
  • Large object pieces with simpler shapes are easier to place than smaller object pieces OP with more complicated shapes.
  • the large air balloon object pieces OP 4 (FIG. 6) are easier to place than the small octopus object pieces OP 2 (FIG. 4).
  • object pieces OP shown in FIG. 7 there exists both large airplane object pieces OP 7 and small airplane object pieces OP 8 interfacing with each other in a single zone of a puzzle of the present invention 20 .
  • the large airplane object pieces OP 7 are more conducive for the less skilled puzzler to place, while the more skilled puzzler may find a challenge in appropriately placing the smaller airplane object pieces OP 8 .
  • the mechanism of object piece OP construction can also create clearly demarcated subdivisions. Similar to shaped protrusions SP, a puzzle can have one zone constructed from interconnected object pieces A while another zone is constructed from different interconnected object pieces B, e.g., OP 1 and OP 2 in FIG. 4. Furthermore, similar interconnected object pieces OP, but of distinctly contrasting sizes, can demarcate a puzzle into various zones, thereby effecting subdivision, e.g., OP 3 ′ and OP 3 ′′ as shown in FIG. 3.
  • object piece OP zone demarcation is based upon distinct object piece OP size differences.
  • this allows a user to distinctly place a piece in a particular zone with clear demarcation between the zones of similarly-shaped, but dissimilar-sized, object pieces OP.
  • a recognizable image e.g., the rainbow, cloud, sun, etc. as shown in FIGS. 1 - 2
  • an image of sea life can be depicted when the object pieces OP 1 and OP 2 are assembled.
  • puzzle frame pieces PFP The last mechanism of puzzle construction is known as puzzle frame pieces PFP and are depicted most clearly in FIG. 5.
  • These puzzle frame pieces PFP comprise large subdivisions of the entire puzzle, usually from 1 ⁇ 8 to ⁇ fraction (1/16) ⁇ of the entire puzzle's surface area.
  • Each PFP has either a large central opening/pieces or multiple interior openings/pieces, all of which can be referred to as “sub-pieces”. For example, as shown most clearly in FIG.
  • PFP 1 has a large star-shaped central opening 28 and a corresponding star-shaped element 30 ; furthermore, PFP 2 is an example of a PFP having multiple interior openings 32 and 34 , with corresponding elements 36 and 38 ; another example of this is shown by the elements 35 , 37 and 39 in PFP 16 -PFP 18 , respectively, in FIG. 3.
  • each of the multiple interior openings/elements can themselves have an interior opening/element, which can be referred to as “inner pieces”.
  • PFP 4 comprises a plurality of multiple interior openings, (one of which is indicated at 40 ) wherein each of these has its own opening/element (one of which is indicated at 42 ). Each of these openings can be completed by placing the corresponding element, thereby requiring skill levels from the most basic to very advanced. Thus, heterogeneity of skill level and subdivisions are accomplished using the PFPs.
  • the construction of the PFPs provide puzzle demarcation into large areas, as shown most clearly in FIG. 5, each of which can act as a “sub-puzzle” to various players and can be assigned to these players based on their skills.
  • the puzzle frame pieces PFP 3 -PFP 15 are shown by way of example in FIG. 5.
  • PFPs can be incorporated into the puzzle of the present invention 20 and abut with and connect to other PFPs, such as those shown by PFP 3 -PFP 15 in FIG. 5.
  • the periphery of these PFPs utilize conventional regular jigsaw-shaped puzzle piece cuts 46 .
  • PFPs can abut/connect with areas of the puzzle of the present invention 20 comprised of object pieces OP and shaped protrusions SP.
  • PFP 16 -PFP 18 comprise shaped protrusions SP along their peripheries for connecting with corresponding shaped protrusion puzzle pieces.
  • FIG. 1 shows PFP 1 and PFP 2 using shaped protrusions SP (e.g., SP 1 ) along their peripheries.
  • interconnected object pieces OP can used as the sub-pieces within the puzzle frame pieces PFP, such as those shown by OP 9 in PFP 11 of FIG. 5 or OP 10 in PFP 16 of FIG. 9.
  • Another variation comprises sub-pieces using shaped protrusions SP 7 .
  • shaped protrusions/recesses SP 7 form elephant trunks.
  • a further variation is to have the sub-pieces comprise traditional jigsaw puzzle pieces, such as those shown at 48 in PFP 9 of FIG. 5 and at 50 of PFP 18 in FIG. 9.
  • the multiple interior openings/elements of the PFPs may have a common theme with the overall image formed when the puzzle is assembled, e.g., “things in the sky” forms the common theme in FIGS. 1 - 2 between the image formed from the assembled puzzle pieces (e.g., a rainbow, the sun, a cloud) and the multiple interior openings/elements (e.g., stars 30 , 36 , 38 etc.) of the PFP 1 and PFP 2 .
