DESCRIPTION OF VARIOUS EMBODIMENTS
Various apparatuses or processes will be described below to provide an example of an embodiment of each claimed invention. No embodiment described below limits any claimed invention and any claimed invention may cover processes or apparatuses that are not described below. The claimed inventions are not limited to apparatuses or processes having all of the features of any one apparatus or process described below or to features common to multiple or all of the apparatuses described below. It is possible that an apparatus or process described below is not an embodiment of any claimed invention. The applicants, inventors or owners reserve all rights that they may have in any invention disclosed in an apparatus or process described below that is not claimed in this document, for example the right to claim such an invention in a continuing application and do not intend to abandon, disclaim or dedicate to the public any such invention by its disclosure in this document.
Referring to FIGS. 1 and 2, a plurality of first pieces 20 is shown. The first pieces 20 are puzzle pieces configured for assembly to form a generally planar first layer 22. The first layer 22 is generally planar but need not be perfectly flat, and for example can contain relief features (not shown). The first pieces 20 can be formed of paper or plastic foam.
The first pieces 20 can be of various complementary sizes and shapes and can interlock with one another according to a typical jigsaw pattern to form the first layer 22. For the purposes of illustration and for clarity, only a portion of the first layer 22 is shown formed of the first pieces 20 interlocking in a jigsaw pattern, but the jigsaw pattern extends across the first layer 22 in its entirety. Although the first pieces 20 are shown interlocking according to a jigsaw pattern to form the first layer 22, connecting configurations other than a jigsaw pattern are possible.
A top surface of the first layer 22 can include various graphic elements 24. The graphic elements 24 can represent various features of a particular geographic region from an aerial viewpoint. The graphic elements 24 can complement relief features, if any. The graphic elements 24 can include a plurality of image elements 26 that correspond to structure pieces, as described in further detail below.
The first layer 22 can include a plurality of retaining elements 28 sized and shaped to retain structure pieces (not shown). The retaining elements 28 can take the form of depressions that extend partially from the top surface towards the bottom surface of the first layer 22, or the retaining elements 28 can take the form of voids that extend fully between the top and bottom surfaces of the first layer 22. Various structure pieces can be configured to be mounted in the retaining elements 28 by, for example but not limited to, friction fit engagement.
Referring to FIG. 3, a plurality of second pieces 30 is shown. The second pieces 30 are puzzle pieces configured for assembly to form a generally planar second layer 32 on top of the first layer 22 in a parallel relationship thereto. The second layer 32 is generally planar but need not be perfectly flat, and for example can contain relief features (not shown). The second pieces 30 can be of various complementary sizes and shapes allowing them to interconnect with one another (as illustrated). Alternatively, the second pieces 30 can also interlock with one another according to a jigsaw pattern, similar to that of the first pieces 20. Other connecting configurations are possible for the second pieces 30 to form the second layer 32.
The second pieces 30 can be formed of paper or plastic foam. A top surface of the second layer 32 can include various graphic elements (not shown) that, for example, represent various features of the geographic region from an aerial viewpoint. Optionally, graphic elements provided on the first or second layers 22, 32 can include glow-in-the-dark elements.
The second layer 32 includes a plurality of retaining elements 34 sized and shaped to retain structure pieces (not shown). The retaining elements 34 can take the form of depressions that extend partially between the top surface towards the bottom surface of the second layer 32, or the retaining elements 34 can take the form of voids that extend fully between the top and bottom surfaces of the second layer 32, as described in further detail below.
FIGS. 4 and 5 show modified first and second layers 22a, 32a in accordance with another example that is similar to the example shown in FIGS. 2 and 3. The first pieces 20a are puzzle pieces configured for assembly to form a generally planar first layer 22a. The first pieces 20a include at least one anchoring piece 36 that is elevated relative to a top surface of the first layer 22a when assembled. The second pieces 30a are configured for assembly with the anchoring pieces 36 to form the second layer 32a. The first and second layers 22a, 32a can have similar height dimensions, and the anchoring pieces 36 can have a height dimension that is similar to the height dimension of the second layer 32a so that top surfaces of the anchoring pieces 36 are generally flush with a top surface of the second layer 32a. 
During manufacturing, the anchoring pieces 36 can be formed by bonding a first piece with a corresponding second piece to form the anchoring piece 36 having a suitable height dimension. For ease of manufacture, the first piece can be sized generally larger in area than the corresponding second piece, so that perfect alignment of the first and second pieces is not necessary when bonding the pieces together.
Referring to FIGS. 6A, 6B and 7, the second pieces 30 forming the second layer 32 can each include one or more of the retaining elements 34. Each of the retaining elements 34 can be sized and shaped to receive a respective structure piece 38 in, for example but not limited to, friction fit engagement. Each of the retaining elements 34 can be sized and shaped in correspondence with respective structure pieces 38 to allow a person to match the retaining elements 34 with the structure pieces 38.
Each of the structure pieces 38 can represent a three dimensional structure or landmark of the geographic region. The structure pieces 38 can be formed of hollow or solid plastic. Optionally, the structure pieces 38 can include glow-in-the-dark elements.
As illustrated, the retaining elements 34 can include or take the form of voids 40 that extend between top and bottom surfaces of the second layer 32 (see for example FIG. 9). Each particular structure piece 38 can be received in friction fit with a respective one of the voids 40 of the second layer 32, and thus the structure pieces 38 can engage the first layer 22 when mounted.
As mentioned above, a top surface of the first layer 22 can include a plurality of image elements 26. The image elements 26 can be arranged in alignment with the voids 40 of the second layer 32 so that the image elements 26 are visible through the voids 40. The image elements 26 of the first layer 22 that are visible through the voids 40 can include indicia to allow a person to match the voids 40 with a respective one of the structure pieces 38. For example, the image elements 26 can include a “birds-eye view” aerial representation of the top of a particular one of the structure pieces 38 (see FIG. 6B), which can allow a person to match the particular one of the structure pieces 38 with a respective one of the voids 40. In other examples, the image elements 26 can include text or numbering corresponding with the particular structure piece 38 to allow a person to match the structure piece 38 with a respective one of the voids 40.
Referring to FIGS. 8 to 12, the first layer 22, the second layer 32 and the structure pieces 38 can be provided together as a kit for assembly into a completed puzzle 42 that is a three dimensional representation of a geographic region.
In some examples, the completed puzzle 42 can take the form of a “cityscape”, in which the geographic region is a city, and the structure pieces 38 represent buildings within the city. In the particular example illustrated, the geographic region is New York City, and the structure pieces 38 represent notable buildings, bridges and other structures in New York City. However, it should be appreciated that the teachings herein are not limited to cityscapes and that representations of various other geographic regions are contemplated.
As illustrated, the structure pieces 38 can be sized and shaped relative to one another according to a non-scale relationship, which allows for the placement of relatively small but notable structures to be included along with larger structures in the puzzle kit. If the structures arranged according to a non-scale relationship, the completed puzzle 42 results in a “caricature” of the geographic region, rather than a true or scale representation thereof.
The structure pieces 38 can be indexed for assembly. For example, the structure pieces 38 can be indexed according to date of construction of the respective building, size of the respective building, neighborhood of respective building, etc. The puzzle kit can include written material (for example, a poster or a small booklet) including educational information about the buildings arranged according to the index. A person assembling the puzzle kit can, according to the index, sequentially engage each of the structure pieces 38 with its respective retaining element 28, or 34 of the first or second layers 22, 32 to mount the structure pieces 38 to the first and second layers 22, 32.
While the above description provides examples of one or more processes or apparatuses, it will be appreciated that other processes or apparatuses may be within the scope of the accompanying claims.
