Abstract:
The present invention is an educational toy and puzzle. The user of the invention is given multiple patterns, preferably paper patterns. Each pattern can be assembled into a box and then each box may be connected or interlocked, with the resulting combination of blocks producing a specific result, while at the same time will allowing the user to creative. In doing so they the user, likely a child, will sharpen their own problem solving skills all while learning hand-eye-coordination and dexterity in a fun and unique new way. In the most basic terms the invention can be characterized as building blocks. Building blocks that when interlocked or connected with additional such blocks build an overall image, design or series of words on the surface by adjoining the blocks side by side, as one would typically place puzzle pieces side by side, so as to create the desired resulting display configuration.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of earlier priority as a result of a provisional patent application (60/858,160) that was filed on Nov. 10, 2006. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    This invention relates generally to an educational folding toy and puzzle. 
         [0004]    2. Background 
         [0005]    Currently there are a number of solutions for educational toys and puzzles. Some of these solutions attempt to assert themselves as educational toys but these solutions fail to meet the needs of the industry because they simply do not push the end-user to strive for a new experience and in turn educate themselves. Other solutions attempt to urge the users to develop and refine new skill sets but these solutions are similarly unable to meet the need of the industry because they don&#39;t engage their audience enough to hold their attention before they put the item down. Still other solutions seek to achieve education through creativity but these solutions also fail to meet the needs of their industry because they don&#39;t provide their customers with the proper tools to achieve by using truly creative measures which would allow the customer to learn new experiences through creativity. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention advantageously fills the aforementioned deficiencies by providing an educational folding toy and puzzle that provides a brand new kind of building block and set of blocks that can be connected as a three-dimensional puzzle. In the most basic terms the invention can be characterized as building blocks. As an educational toy, children will interact with these blocks to learn their ABC&#39;s in a fun and unique new way. Preferably designed with 36 pages (including 26 letters and 10 numerals) children will work on one letter at a time, allowing time to focus on each individual character as they color and subsequently fold every page of the book into 36 separate blocks. 
         [0007]    Every page once folded forms a six sided block, four of which have content, which can include, among other things: an uppercase letter, a lowercase letter, a playful letter (which is the puzzle side) and a sign equivalent (American Sign Language) for each of the 26 letters. Children can first learn to spell words by interlocking blocks together next they can form sentences by inserting spaces and again by interlocking these blocks. Finally they will solve the puzzle to learn the proper order of their ABC&#39;s. 
         [0008]    The invention is not limited to blocks that can assist in the learning of ABCs, as described in the previous paragraphs. The same six sided block structure can also be used much like a coloring book would be used, with images appearing on the flat pages to be colored or even simply pre-printed material that could be used as clues in solving a puzzle. In this version of the present invention when the blocks are formed (preferably after coloring has taken place) the blocks can be arranged side by side and top to bottom to create an overall image or picture. Therefore, each side of the block would be akin to a piece of a puzzle. 
         [0009]    As an entertainment/educational toy, children can interact with these blocks in a fun and unique new way. Beginning by coloring flat pages that will fold to create separate blocks each of which have four “fragmented” images, one on each side of the block. As time passes and they get tired of the mural they can disassemble and reassemble the fragments into a new mural. The children can continue this until they have completed all of the different murals. 
         [0010]    The educational aspect of this piece is in the skill set required to produce each mural. As the children color the four fragments on each of the 36 pages they will have to associate each fragment of the puzzle with the larger whole so that as they color the colors are consistent across all the pieces. Additionally the skills required for properly folding these blocks teach them dexterity and improve hand-to-eye-coordination. 
         [0011]    Each piece can be converted from a flat sheet to a single block by following the folding techniques outlined below. A block is created by working with an individual flat sheet placed in landscape orientation and then by folding each center panel in a horizontal manner working from right to left at a 90 degree angle along each of the vertical scores. At the same time you are folding from right to left you also fold the top and bottom panels again at 90 degrees this time along the horizontal scores until you have created a completely enclosed six sided box. The final step is to ensure the box is “locked” closed which is achieved by using the panel(s) on the fifth column as a latching mechanism. 
         [0012]    Each piece is created from one component that is a sheet of paper, or similar material (such as poster board, newspaper, cardboard, plastic, recycled materials, etc.) that utilizes a series of cuts and folds to achieve a desired outcome. The material is divided up using a series of cuts and folds into three rows and five columns that when folded using 90 degree angles will yield one block. These blocks can be connected in a horizontal manner so that they can then create a wider structure made up of multiple blocks. Additionally they can be connected in a vertical manner again to achieve tall structure made up of multiple blocks. Even further they can be concurrently connected both horizontally as well as vertically to achieve a larger overall structure, which can with enough horizontal and vertical blocks make up a wall or barrier. 
         [0013]    The best way to make this invention is by printing a series of different images on one side of the different sheets, then applying a diecut which will trim every sheet to a predetermined size all while applying six scores (two horizontally and four vertically) and eight cuts (all vertically) exactly the same on every sheet. Although 36 sheets are used in this example, the number of sheets can indeed vary and any number of sheets and pages can be used. After the diecut the sheets will be collated and packaged together in a flat form. The purpose of the six scores and eight cuts are to create three rows and five columns on every sheet which will become the 15 panels that are required to fold each of the blocks. Four of the columns provide the first four sides of the six-sided blocks while the fifth column acts as a latching mechanism to hold each individual block together. The 1 st  and 3 rd  or top and bottom rows provide the remaining two faces of each block. An additional option is that the 36 pages could be bound together using anyone of several conventional book-binding methods (perfect-binding, tape binding, wire-o binding, spiral binding, velo binding, etc.) which would allow the pages to hold together in a cohesive book which the user could color like a conventional coloring book until they are ready to tear out each page, along a perforated line, to fold into a block. 
         [0014]    It is therefore an object of the present invention to assist children in learning their ABC&#39;s in a fun hands-on way as well as teaching them sign language by transforming a static coloring book into an interactive 3D mural. It assists children with problem solving, coordination, dexterity and teaches them to explore and be creativity. 
         [0015]    It is a further object of the present invention to turn a 2D coloring book into a 3D puzzle. It transforms a static coloring book into an interactive 3D mural. It assists children with problem solving, coordination, dexterity and teaches them to explore and be creativity. 
         [0016]    It is still a further object of the present invention to allow for the creation of a three-dimensional object, such as a castle for example, from a flat 2D book. 
         [0017]    Further still, it is an object of the present invention to improve one&#39;s problem solving skills, improve one&#39;s dexterity, deliver a reward through a sense of achievement, instill a sense of creativity, assist in the learning of the alphabet, assist in learning how to spell and assist in developing three-dimensional spatial skills. 
         [0018]    Finally, it is an object of the present invention to provide an educational folding toy and puzzle that does not suffer from any of the problems or deficiencies associated with prior solutions. 
         [0019]    The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with both this summary, the detailed description and any preferred and/or particular embodiments specifically discussed or otherwise disclosed.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0066]    The present invention is directed to educational folding toy and puzzle. Each piece is created from one component that is a sheet of paper, or similar material (such as poster board, newspaper, cardboard, plastic, recycled materials) that utilizes a series of cuts and folds to achieve a desired outcome. The material is preferably divided up using a series of cuts and folds (scores) into three rows and five columns which equal a total of 15 individual panels per sheet that when folded using 90 degree angles will yield one block. Additionally once the blocks have been created they can be interlocked or connected. 
         [0067]    Of the single component (i.e., one sheet or unit of whatever material is selected) it is in fact the 15 individual panels that provide the function for this piece. Four panels will preferably have content to color, they are preferably located in the center of the sheet or rather the 2 nd  row. At the beginning the user is preferably instructed to color these four panels. After coloring has finished, the user will fold the pieces together along the 5 columns at 90 degree angles while at the same time folding in the 1 st  row and 3 rd  row, again at 90 degree angles to form a basic block. The purpose of the 1 st  and 3 rd  rows are to provide the block with the ability to hold together. 
         [0068]      FIG. 1A  depicts the front side of an individual sheet in a vertical view as the viewer would read it. A 1  is a the front side of an individual sheet which is divided into 15 separate panels which are comprised of a series of five separate left flaps:  12 ,  14 ,  16 ,  18  and  20 ; five middle panels:  2 ,  4 ,  6 ,  8  and  10 ; and finally a series of five separate right flaps:  22 ,  24 ,  26 ,  28  and  30 . 
         [0069]      FIG. 1B  depicts the back side of  FIG. 1A  in a horizontal view as the viewer would fold it. Here you can readily see the five columns and three rows. A 2  is the back side of an individual sheet with the top of the sheet on the right side and the bottom of the sheet on the left side. There are two of horizontal scores:  64  and  66  and four vertical scores:  56 ,  58 ,  60  and  62 . While  48 ,  50 ,  52  and  54  depict cuts that create the five left flaps:  12 ,  14 ,  16 ,  18  and  20 . The five right flaps:  22 ,  24 ,  26 ,  28  and  30  are created from cuts:  40 ,  42 ,  44  and  46 . 
         [0070]      FIG. 1C  depicts the folding of an individual sheet to form a single block. Working from the back side of the sheet A 2  the user will fold from the right working towards the left along the horizontal scores:  64  and  66  in addition to all the vertical scores:  56 ,  58 ,  60  and  62 . 
         [0071]      FIG. 1D  depicts the next stage of folding an individual sheet to form a single block. As the user is folding the piece flap  22  on the top should be placed underneath flap  24 ,  24  should be placed under  26  and  26  should be placed under  28 . 
         [0072]      FIG. 1E  depicts the next stage of folding an individual sheet to form a single block from a top angle. As the block comes to a close flap  30  should be on top of flap  22  but underneath flap  24 . 
         [0073]      FIG. 1F  depicts the same stage as  FIG. 1   e  of folding an individual sheet to form a single block from a bottom angle. From the bottom perspective flap  12  should be on top of flap  14 , flap  14  should be on top of flap  16 ,  16  should be on top of  18 ,  18  should be on top of  20  and  20  should be on top of  12 . 
         [0074]      FIG. 1G  depicts one completed block. B illustrates a single completed block in which flap  30  is resting above  28 ,  28  is resting above  26 ,  26  is resting above  24  and  24  is resting above  30 . 
         [0075]      FIG. 1H ,  FIG. 1I  and  FIG. 1J  all relate to the situation where two or more blocks will be connected or interlocked. Specifically,  FIG. 1H  shows the invention with the left flaps:  14 ,  16 ,  18  and  20  of block B facing your left and the right flaps of the second block B facing your right pull them apart ever so slightly  35 . The facade fragment  10  of the left block should be facing you while the top façade fragment  10  of the right block faces up. 
         [0076]      FIG. 1I  depicts two completed blocks B twisting together to interlock. Rotate the block on the right 90 degrees towards you or inversely rotate the block on the left 90 degrees away from you. You can repeat this step as many times as you like by adding additional blocks to the right or left. 
         [0077]      FIG. 1J  depicts two completed blocks interlocked together. After you have rotated the two blocks B the two facades  10  align with each as does the other three sides  8 ,  6 , and  4  of the blocks which begin to form a greater meaning. 
         [0078]      FIGS. 1K and 1L  are an overview of all pieces and depict how multiple blocks are connected so as to bring together the pieces of a puzzle to depict some type of image, saying or graphic as a mural which is represented here as C. 
         [0079]      FIG. 2A  depicts an alternate version of the book in  FIG. 1  represented here in closed form with 100 being the cover. 
         [0080]      FIG. 2B  depicts panel  102  opening to the left 180 degrees while page  104  opens to the right 180 degrees. 
         [0081]      FIG. 2C  depicts panels  110 ,  112 ,  114  and  116  opening upward 180 degrees. 
         [0082]      FIG. 2D  depicts panels  120 ,  122 ,  124  and  126  opening downward 180 degrees. 
         [0083]      FIG. 2E  depicts panels  130 ,  132 ,  134  and  136  opening upward 180 degrees. 
         [0084]      FIG. 2F  depicts panels  140 ,  142 ,  144 ,  146 ,  180 ,  182 ,  184 ,  186 ,  150 ,  152 ,  154  and  156  opening downward 180 degrees as one large group. 
         [0085]      FIG. 2G  Reference D depicts the entire “book” as the user would view it when displayed as an open, flat sheet. In this example  200  represents the optional battlements (a parapet at the top of a wall, usually of a fort or castle). Additionally panel  138  opens to the right 180 degrees, which will later be used as a locking mechanism.  190  is the slit in which panel  138  inserts to lock. In it&#39;s completely open and flat form this “book” is comprised of five columns (four columns are used for graphics and one column for the tabbed locking mechanism) and six rows creating a total of twenty five panels, each of which play a vital role in the functionality of this “book.” D also represents the bottom twelve panels:  210 ,  212 ,  214 ,  216 ,  220 ,  222 ,  224 ,  226 ,  130 ,  132 ,  134  and  136  folding upward 180 degrees again as one large group. 
         [0086]      FIG. 2H  depicts panels  140 ,  142 ,  144  and  146  folding downwards 90 degrees. 
         [0087]      FIG. 2I  depicts panel  150 ,  152 ,  154  and  156  folding upwards 90 degrees. 
         [0088]      FIG. 2J  depicts the panels of the book starting to enclose. This is achieved by overlapping panels. On the top row panel  130  goes over panel  132 ,  132  over  134  and  134  over  136 , while on the bottom row panel  150  goes over panel  152 ,  152  over  154  and  154  over  156 .  170 ,  172 ,  174  and  176  are optional flaps that open to assist the vertical panels to remain vertical. 
         [0089]      FIG. 2K  depicts panel  156  on the bottom row overlapping panel  150  and  136  on the top row overlapping  130 . 
         [0090]      FIG. 2L  depicts tab  138  inserting into the slit  190   
         [0091]      FIG. 2M  depicts the book in it&#39;s completed 3-D model form. In this example the completed form is a castle, however this form is by no means limited to a castle. This form could just as easily be bricks to create a house or a framework to create a space station or even architectural blocks to create buildings in a city. This is no more than a representation of the possibilities this form can embody. 
         [0092]      FIG. 2N  depicts the top of the castle in which panel  130  is on top of panel  132 , panel  132  is on top of  134 ,  134  is on top of  136  and  136  is on top of  130 . 
         [0093]      FIG. 2O  depicts the bottom view of the castle in which panel  120  is on top of panel  126 , panel  126  is on top of  124 ,  124  is on top of  122  and  122  is on top of  120 . 
         [0094]      FIG. 3A  depicts two A 2  sheets coming together to create D in  FIG. 3C . Each A 2  sheet is comprised of five columns and three rows. 
         [0095]      FIG. 3B  is a transitional example of two A 2  sheets combined with the sizes of the panels redefined to create a single sheet which now has five columns and six rows. In this example the fifth column has been converted to a tab. 
         [0096]      FIG. 3C  is sheet D in final flat form which displays the preferred diecut. Certain pieces of material have been removed so that when it&#39;s folded down the material the panels are created from will not buckle which will create a neatly folded book. 
         [0097]      FIG. 4A  depicts the flat sheet D as first seen in  FIG. 2G . 
         [0098]      FIG. 4B  depicts an alternative method for creating the flat sheet D. F uses the same base form as D (five columns and six rows) but has replaced the removed angled pieces of material with squared off pieces. Additionally a bottom tab and slit have been added. 
         [0099]      FIG. 4C  again depicts an alternative method for creating the flat sheet D. G uses the same base form as D (five columns and six rows) but has removed the tab as the locking mechanism and replaced it with slits in which when folded the individual panels can, slide into. In short there are a number of ways this form can be created, with only several examples displayed here. What is important is the overall form as a whole and not the minor details that alter the specifics of the form which included items like the tabbed latching mechanism, the battlements, the small flaps that open on the top and all the various possibilities of altering the diecut to optimize the method of folding down the flat sheet to it&#39;s closed state. 
         [0100]      FIG. 5A  depicts a different method of folding the book that allows the user to “hide” the battlements by folding them into the book which in turn creates a simpler box. Fold panel  160 ,  162 ,  164  and  166  behind panels  180 ,  182 ,  184  and  186 . 
         [0101]      FIG. 5B  depicts the book coming together as a box. This again is achieved by overlapping panels. On the top row panel  130  goes over panel  132 ,  132  over  134  and  134  over  136 , while on the bottom row panel  150  goes over panel  152 ,  152  over  154  and  154  over  156 . 
         [0102]      FIG. 5C  depicts the box enclosing where  138  will be inserted into 190. 
         [0103]      FIG. 5D  depicts the finished box in it&#39;s simpler form. 
         [0104]      FIG. 6A  depicts a method of locking multiple boxes together in a vertical manner to create a taller structure. The basic method of folding for the top piece remains the same as  FIG. 2  except panels  122  and  126  should be left “hanging” down. For the second and third boxes the method of folding used in  FIG. 5  is used, again leaving panels  122  and  126  hanging down. For the bottom box or base the technique used in  FIG. 5  is applied to construct the box. As the boxes begin to stack on top of one another all 152 panels should be inserted in the gap in front of  100  while all the 126 panels should be inserted in the small gap behind the 104 panels. 
         [0105]      FIG. 6B  depicts the completed tower structure. 
         [0106]      FIG. 7A  depicts a method for locking two boxes together to act as one longer box. On the first castle use the same folding technique show in  FIG. 2  except panel  164  will be inserted behind panel  184  when closing the castle. 
         [0107]      FIG. 7B  depicts the castle closing. 
         [0108]      FIG. 7C  depicts the finished castle I which has one of the battlements (panel  164 ) hidden. 
         [0109]      FIG. 7D  depicts a second castle which has already been folded using the standard method shown in  FIG. 2   
         [0110]      FIG. 7E  depicts the two castles beginning to lock together by inserting panel  110  on E behind the gap in panel  106  on I. 
         [0111]      FIG. 7F  again shows panel  110  further being inserted into I. 
         [0112]      FIG. 7G  depicts the two castles locked together as one bigger castle. This technique can be used over and over again to create many different shapes. Furthermore this folding technique can be used in conjunction with the folding techniques displayed in  FIG. 2 ,  FIG. 5  and  FIG. 6  to create many new and exciting creations. 
         [0113]    Alternatively, the present invention can be formatted as a single flat book that unfolds to erect a self-contained structure, such as but not limited to a castle. Additionally by combining multiples you can continue to build even more castles, or a village. Once a user has mastered the art of folding the first castle then they can exercise this new skill set by building and interlocking additional castles together. In this step the user is free to create as many different castles as the kit can create. In this manner you can create many different shapes by experimenting and combing multiple books. Since not everyone can build something as complicated as a 3D model from scratch, this toy fills that void, it provides the pre-fabricated components of a castle, that when assembled, enables the user to build a 3D castle on their own resulting in pride and self-confidence. 
         [0114]    The castle is a single component that is one sheet of paper, or similar material, such as poster board, newspaper, cardboard, plastic, recycled materials, etc. which is divided up using a series of cuts and folds into 4 columns and 6 rows which equal a total of 24 individual panels plus one additional column for a latch which is presented to the user in a folded down shape that resembles a small book. Of course, there is no magic to the number of panels, and the panels can number more than or less than 24, although 24 plus the latch is preferred. 
         [0115]    The best way to make the castle is by printing on one or both sides of a single sheet, then applying a diecut which will trim every sheet to a predetermined size all while applying a series of scores and cuts. After the diecut the sheets will be folded down into a book and packaged in kits of varying amounts. The diecut is to elaborate to describe in writing alone as such a reference to the patent drawings is mandatory to understand what is required of the diecut. Please see  FIG. 3C  of the patent drawings for a detail of the diecut. 
         [0116]    The simplest way to make this product is by printing on one or both sides of a single sheet, or not printing at all, then applying a diecut to the sheet of paper or similar material (magnetic paper, plastic, thin foam, cardboard, etc.) which will then trim every sheet to a predetermined size all while applying a series of scores and cuts. After the diecut the sheets could opt not to be folded down into a book and opt to sell as flat sheets. 
         [0117]    The battlement ( 200 ), which is the decorative element on the top of the castle, may be removed and replaced with other unique decorative elements. Furthermore, some or all of the flaps on the interior view ( FIG. 2J :  170 ,  172 ,  174  and  176 ) can be removed, replaced or altered. Similarly, the latch ( FIG. 2G :  138 ) can be removed, replaced or altered. Even further the slit ( FIG. 2G   190 ) can be replaced, removed or altered.
