Abstract
A three-dimensional jigsaw puzzle consisting of one or more two-dimensional puzzle parts, each consisting of two or more jigsaw puzzle pieces. The puzzle parts can interconnect using leg and hole connectors to form the three-dimensional object. Each puzzle part is fixed using fixing sheets which are precut to match the format of its corresponding puzzle part. Each puzzle part can have puzzle pieces which can be bent to create corners. The bending is achieved by applying a reinforced tape along the bending line on the inner side, and by having a straight cut on the outer side of the corner penetrating the cut through the puzzle piece, but without cutting the tape. The puzzle pieces are laminated with paper that can bear an image on both sides. The puzzle parts can have a reinforcement bar glued on the non-visible side so that they retain the desired planar shape.

DETAILED DESCRIPTION OF THE INVENTION
[0066] The three-dimensional object 26 comprises one or more two-dimensional puzzle parts which are bent if/where applicable as shown on FIG. 15 and FIG. 16, and connected to one another as shown on FIG. 17, FIG. 18 and FIG. 19. Each two-dimensional puzzle part consists of two or more jigsaw puzzle pieces which are fixed using the flexible adhesive fixing sheets 15 once the said puzzle part is assembled.
[0067] Represented in FIG. 1 through FIG. 9 are embodiments of different types of jigsaw puzzle pieces. There are two main types of jigsaw puzzle pieces 23/24/25. The one pictured in FIG. 1 and FIG. 2 which is a jigsaw puzzle piece that cannot be bent 23, consists of a main middle layer of cardboard 2 of between one and three millimeters of thickness laminated with a paper bearing an image on the visible face 1 and laminated also on the non-visible face 3 with a paper that could bear an image. The second type of jigsaw puzzle pieces are the ones that can be bent 24/25, which have two subtypes: one is the single jigsaw puzzle piece which can be bent 24, as pictured in FIGS. 3 and FIG. 4, and the other one is the extended jigsaw puzzle piece which can be bent 25, as pictured in FIG. 5 and FIG. 6. All subtypes of jigsaw puzzle pieces which can be bent 24/25 consist of the same main middle layer of cardboard 2 as that of the jigsaw puzzle pieces that cannot be bent, with an application of a fiber-reinforced adhesive tape 4 which is applied on the inner side of the bending corner. The said fiber-reinforced adhesive tape 4 is applied all along the bending axis line 8, at which the said jigsaw puzzle piece bends to create a corner. Said fiber-reinforced adhesive tape 4 is applied directly on the cardboard 2 and before the paper 1/3 is laminated on the said cardboard 2. Once the said cardboard 2 is laminated on both sides 1/3, then the jigsaw puzzle pieces are cut. There are two types of cuts: one is a full-through cut that will separate all types and subtypes of jigsaw puzzle pieces 23/24/25 by perforating through the whole width of the jigsaw puzzle piece including the cardboard 2, the fiber-reinforced adhesive tape 4 (in the case of the jigsaw puzzle pieces that can be bent 24/25), and the laminating papers on both sides 1 and 3. This cut will produce the separation of all the jigsaw puzzle pieces 23/24/25 by cutting along all the contour lines 6. The second type of cut 10 is used only on jigsaw puzzle pieces that can be bent 24/25 and its purpose is to debilitate the rigid cardboard 2 so that the jigsaw puzzle piece can be bent. The cross-sections in FIG. 4 and FIG. 6 depict both an overall and an expanded detailed view of how the fiber-reinforced adhesive tape 4 is applied along the inner side of the bending corner and it also shows with precision how the cut 10 perforates through the cardboard 2 of the jigsaw puzzle piece 24/25 but does not cut through the fiber-reinforced adhesive tape 4 nor the laminating paper 1 or 3 that is glued over the fiber-reinforced adhesive tape 4. With this construction, the fiber-reinforced adhesive tape 4 acts as a hinge throughout the entire bending axis line 8, so that the jigsaw puzzle piece 24/25 can bend towards the opposite side of the cut 10, as illustrated by the rotation direction 9 in FIG. 3, FIG. 5, FIG. 15 and FIG. 16. Although the drawings illustrating the rotation direction 9 resemble a ninety-degree angle, the corner bending rotation 9 can be of any angle measure between zero and one hundred and eighty degrees.
[0068] In FIG. 3 to 6, both faces of the jigsaw puzzle piece 24/25 are noted as 1 or 3, which means that the visible face 1 and the non-visible face 3 could be either on the inside or on the outside of the bending corner, depending what shape is required to form the three-dimensional object 26.
[0069] In order to assemble each two-dimensional puzzle part 21/22, all types and subtypes of jigsaw puzzle pieces connect to one another by matching each outwards connection 7 of a given jigsaw puzzle piece to its corresponding inwards 5 connection of the jigsaw puzzle piece which connects to it, with the help of the image that is printed on the visible face 1, which continues from one jigsaw puzzle piece to the next. Every jigsaw puzzle piece has at least one connector 5/7, so that it can be connected to other jigsaw puzzle pieces to form a two-dimensional puzzle part 21/22. FIG. 10 and FIG. 13 illustrate how multiple jigsaw puzzle pieces interconnect to one another to form said two-dimensional puzzle part 21/22.
[0070] In addition to the inwards 5 and outwards 7 connectors, which are used to interconnect the jigsaw puzzle pieces to form a two-dimensional puzzle part 21/22, all types and subtypes of jigsaw puzzle piece can have hole connectors 11 as depicted in FIG. 7, and/or L-shaped leg connectors 12 as depicted in FIG. 8, and/or straight leg connectors 13 as depicted in FIG. 9. These hole 11, L-shaped leg 12 and straight leg 13 connectors are used to connect the two-dimensional puzzle parts 21/22 to one another, once each two-dimensional puzzle part 21/22 is assembled and fixed, so that they can form the three-dimensional object 29.
[0071] In order for the two-dimensional puzzle part 21/22 to remain assembled, with all the jigsaw puzzle pieces that it comprises interconnected to one another, it needs to be fixed. FIG. 11 illustrates a thin flexible adhesive fixing sheet 15, which is coated with adhesive on one side 16 and it is not coated on the opposite side 17. This flexible adhesive fixing sheet 15 can bear a printed image on the non-adhesive side 17. In order to protect the adherent face 16 and prevent the adhesive to stick to non-desired surfaces, the adhesive-coated side 16 is covered with a removable backing sheet or liner 18. Each flexible adhesive fixing sheet 15 is trimmed to match the shape of a corresponding two-dimensional jigsaw puzzle part 21/22. If its corresponding two-dimensional puzzle part 21/22 has hole connectors 11, then the matching flexible adhesive fixing sheet 15 will have trimmed the same holes in the same matching positions 19, so that the flexible adhesive fixing sheet 15 does not cover the hole connectors 11 of the two-dimensional puzzle part 21/22.
[0072] As shown in FIG. 11 and FIG. 14, the two-dimensional puzzle part 21/22 has to be placed on a flat surface with the non-visible face 3 facing up, then the flexible adhesive fixing sheet 15 can be removed from the backing sheet or liner 18 and glued onto the non-visible face 3 of the corresponding two-dimensional puzzle part 21/22.
[0073] Some two-dimensional puzzle parts 22 may need extra strength in order to maintain their planar shape while being manipulated to form the three-dimensional object 26. For this purpose, as depicted in FIG. 15, a supporting bar 20 manufactured from cardboard or plastic, between 1.5 and 3.0 millimeters of thickness, with one side coated with adhesive, is glued on top of the flexible adhesive fixing sheet 15 of that said two-dimensional puzzle part 22.
[0074] The two-dimensional puzzle parts with jigsaw puzzle pieces which cannot be bent 21, once they have been fixed using the flexible adhesive fixing sheet 15, are ready to be used to assemble the three-dimensional object 26. As shown in FIG. 16, those two-dimensional puzzle parts with jigsaw puzzle pieces which can be bent 22, once they have been fixed using the flexible adhesive fixing sheet 15, will need to be bent into position before they can be used to assemble the three-dimensional object 26.
[0075] FIG. 17 depicts the connection between two-dimensional puzzle part 22 and 21. In step A, part 22 is aligned with the straight leg connectors 13 facing the corresponding hole connectors 11 from part 21. Once aligned, as shown in step B, the straight connectors 13 from part 22 are inserted into the corresponding hole connectors 11 from part 21. This is one of various types of two-dimensional puzzle part connections. In some cases, more than one leg-to-hole connection Nov. 12, 2013 may connect right next to another let-to-hole connection Nov. 12, 2013, which can lead to complex hole connection shapes 14. These complex hole shapes allow one hole connector 11 to 395 receive more than one leg connectors 12/13, which can connect in different angles.
[0076] FIG. 18 depicts five different connection samples between two-dimensional puzzle parts. In FIG. 18.1., the straight connectors 13 are long and as step A shows, they have to align horizontally to be inserted as shown in step B. In FIG. 18.II., it is the side of a two-dimensional puzzle part that inserts into a hole connector 11 in the corner of the connecting part, this without a connecting leg. In this case, as the arrows show in step A, the inserting panel has to be aligned with the angle of the corresponding hole connector 11 so that it can get inserted as shown in step B. FIG. 18.III. depicts a double L-shape leg connector 12, which gets lined up in step A, inserted in the corresponding hole connectors 11 in step B, and then in step C, the inserting puzzle part slides in the direction of the tip of the L-shaped leg connectors 12 so that the two connecting parts remain locked in position. FIG. 18.IV. shows an L-shaped leg connector 12 in a vertical orientation. In this case, in step A the L-shaped leg connectors 12 are aligned with the corresponding hole connectors 11, in step B they are inserted, and in step C the inserting two-dimensional puzzle part slides down to lock into position. FIG. 18.V. shows two puzzle parts that connect using a combination of straight leg connectors 13 and L-shaped leg connectors 12. Wherein the said straight leg connectors 13 are longer and can be partially inserted into their corresponding hole connectors 11, so that, while part of the said straight leg connectors 13 remains inserted in their corresponding hole connectors 11, the L-shaped connectors 12 can be inserted and slide down for locking into position.
