Description

[Technical field]

[0001] The present invention relates to a sheet for making interlocking blocks and a kit for making interlocking blocks to be used as toys or educational tools. [Background technology]

[0002] Block toys can be stacked horizontally, vertically, etc. to create structures of various shapes, stimulating and nurturing the creator's creativity. (Patent Document 1) [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-87883 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, although it is fun to build structures by stacking blocks, there are few blocks with complex shapes because the blocks are prepared as three-dimensional objects in advance. Combining blocks with simple shapes alone is somewhat uninteresting as a toy or educational tool. It also does not offer the same level of interest as building a three-dimensional object such as a block from a flat sheet. Furthermore, the surfaces of typical blocks are flat, and when stacked, they can slip off, so the stacking structures that can be created are limited, and it is inconvenient to carry the completed blocks around.

[0005] The object of the present invention is to provide a sheet for making assembled block tools that allows the user to enjoy the pleasure of completing a block tool from a flat surface to a three-dimensional object by hand, and the pleasure of using the completed assembled block tools of various kinds. Another object of the present invention is to provide a sheet for making assembled block tools that is lightweight and compact, and can maintain a stable structure even after completion. [Means for solving the problem]

[0006] The sheet for making assembled block tools of the present invention, which solves the above-mentioned problems, is a substantially flat sheet for making assembled block tools that can be folded and cut out and has pieces which are the development diagrams of multiple types of blocks, and cut lines and fold lines are provided on the surface which will be the reverse side when made into a three-dimensional form, and blocks are formed by cutting out the outlines of the pieces indicated by the cut lines and folding along the fold lines to assemble and process them three-dimensionally, and further has a seventh piece which is the development diagram of a small capsule which detachably covers at least one surface of the block, and the small capsules have letters, symbols, figures, patterns and colors applied to their surfaces, and the letters, symbols, figures, patterns and colors applied to the small capsules can be displayed on the surface of the structure formed by combining the blocks.

[0007] This structure allows the user to enjoy the fun of cutting out pieces from a flat sheet, folding them, and creating a 3D object such as a block. By attaching and detaching small capsules to the block, the user can combine and set various pieces of information shown in the small capsules, allowing the user to display new information on the surface of the block at any time, demonstrating the user's originality and ingenuity. The user can continue to enjoy the process of creating the block, as well as after it is completed.

[0008] The sheet for creating assembled block tools of the present invention, which solves the above-mentioned problems, further comprises a sixth piece which is an expanded view of a tray on which the blocks are placed, and an eighth piece which is an expanded view of a capsule which covers the structure formed by combining the blocks, the eighth piece being made of a transparent material, and the piece which is the expanded view of the blocks has cutting guide lines on the surface which will become the back side when the block is made into a three-dimensional shape, and the cutting guide lines consist of connecting piece portion guide lines which respectively correspond to the connecting piece portions and connecting openings which connect the blocks together, and connecting opening guide lines.

[0009] With this configuration, the stacked shape of the blocks can be stably maintained by the tray and capsule, and the stacked structure is difficult to separate even when transported, and is maintained as an integral unit. The connecting pieces and connecting openings make it easy to connect the blocks to each other.

[0010] In the sheet for making assembled block tools of the present invention that solves the above-mentioned problems, the plurality of blocks are assembled block tools comprising a plurality of first blocks formed into equilateral triangular pyramids of the same size, and a plurality of second blocks formed into equilateral pyramids or regular octahedrons with one side formed of an equilateral triangle congruent with one side of each of the first blocks, and a plurality of the following third to fifth blocks are provided as additional blocks, and a pyramidal structure can be formed by combining these blocks by using the plurality of first to fifth blocks, and the third block is a parallelepiped with a rhombic shape formed by connecting two of the equilateral triangles on each side, the fourth block has a front and bottom surface each formed into a trapezoidal shape formed by connecting three of the equilateral triangles, a rear and top surface each formed into an equilateral triangle congruent with the equilateral triangle, and each of both side surfaces is a rhombic hexahedron formed by connecting two of the equilateral triangles, and the fifth block is a nonahedron formed by assembling a regular triangular pyramid of the same shape and size as the first block on any of the surfaces of the fourth block, and the tray a tray having a placement surface for placing the first to fifth blocks, a loop-shaped protruding wall having a regular triangular or square shape in a plan view that protrudes above the placement surface, and the pyramidal structure can be formed by arranging the lowest block of the pyramidal structure among the first to fifth blocks along the inside of the protruding wall, and the outer surfaces of the first to fifth blocks are colored in a plurality of different colors, and when the pyramidal structure is formed, the pyramidal structure It is possible to have each side of the pyramidal structure be the same color, or to have the multiple side surfaces of the pyramidal structure be colored differently from one another, and the color coding of the outer surfaces of the multiple first to fifth blocks is done with the equilateral triangle as the smallest unit, and for sides larger than this smallest unit equilateral triangle, in addition to being entirely a single color, sides may also be provided that are colored in two or three colors, and the assembly block tool creating sheet has first to fifth pieces as developments of the first to fifth blocks, respectively.

[0011] With this configuration, the simplicity of assembling the blocks is eliminated, making it more difficult and requiring more thinking ability, making it more interesting as an intellectual or educational toy than the conventional technology and less likely to cause boredom. Since the sides of the pyramidal structures can be colored, it becomes necessary to consider the arrangement of the colors, requiring more advanced thinking ability and making it more interesting.

[0012] The sheet for making assembled block tools of the present invention, which solves the above-mentioned problems, has a connecting piece portion formed from the connecting piece portion guide lines that has a shape protruding from the face of an equilateral triangle, and a connecting opening portion formed from the connecting opening guide lines that is formed on the face of an equilateral triangle and has a roughly rectangular shape that allows the connecting piece to be detached, the connecting piece portion of one block and the connecting opening portion of the other block detachably connect the blocks, and the longitudinal width of the connecting opening portion is approximately 30% or more and approximately 80% or less of the diameter of a circle inscribed in an equilateral triangle, which is the smallest unit of a block.

[0013] According to this configuration, the blocks can be easily connected to each other by the connecting pieces and the connecting openings, and can also be easily attached and detached.

[0014] The sheet for creating assembled block tools of the present invention, which solves the above-mentioned problems, is capable of forming the pyramidal structure even when using only the multiple first and second blocks without using the additional blocks, and the expansion diagram of the blocks includes only the first and second pieces as the expansion diagrams of the first and second blocks.

[0015] According to this configuration, it is possible to play in two ways: by using additional blocks to build a pyramidal structure, or by building a pyramidal structure without using additional blocks. This expands the range of ways to play. In addition, the way to play can be selected according to the intellectual development level of the user, such as a child.

[0016] In the sheet for making assembled block tools of the present invention that solves the above problems, the pyramidal structure is a triangular pyramidal structure, and includes a first piece and a second piece calculated by the following formula, a=x×(x 2 +2) / 3, b = x × (x 2 -1) / 6, where x represents the number of steps of the triangular pyramidal structure, a represents the number of the first blocks and the first pieces, and b represents the number of the second blocks and the second pieces. The number of steps x of the triangular pyramidal structure is x≧1.

[0017] With this configuration, it is possible to prepare sheets with the same number of pieces required to create a triangular pyramid structure.

[0018] The kit for making a combination block tool of the present invention, which solves the above-mentioned problems, includes any one of the sheets for making a combination block tool described above.

[0019] According to this configuration, a three-dimensional object such as a block can be easily formed from the sheet for making assembled block tools. Effect of the Invention

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings, in which: FIG. (Embodiment 1)

[0023] A first embodiment of the present invention will be described. FIG. 1(a) shows an example of a sheet 100 for making a block tool, which includes pieces that are development views of a block tool according to an embodiment of the present invention. A block tool including a plurality of blocks can form a predetermined structure by stacking the plurality of blocks. The sheet 100 for making a block tool includes pieces that are development views of blocks required for stacking the block tools to form a predetermined structure. The sheet 100 for making a block tool shown in FIG. 1(a) includes a first piece 11, a second piece 12, and a third piece 13. The first piece 11, the second piece 12, and the third piece 13 are development views of blocks having different three-dimensional shapes. The sheet 100 for making a block tool shown in FIG. 1(a) may further include a fourth piece 14 and a fifth piece 15. The fourth piece 14 and the fifth piece 15 are development views of blocks having three-dimensional shapes different from each other from the other blocks. FIG. 1(b) shows an example of pieces that are development views of individual blocks of a block tool according to an embodiment of the present invention. The first piece 11 is a piece that is an expansion plan of the first block 1. The second piece 12 is a piece that is an expansion plan of the second block 2. The third piece 13 is a piece that is an expansion plan of the third block 3. The fourth piece 14 is a piece that is an expansion plan of the fourth block 4. The fifth piece 15 is a piece that is an expansion plan of the fifth block 5.

[0024] The first block 1 to the fifth block 5 constituting the assembled block will be described in detail later.

[0025] The first piece 11 to the third piece 13 provided on the sheet 100 for making a block tool shown in FIG. 1(a) can be cut along the contour line and folded along the dotted line to assemble into a three-dimensional shape to make the first to third blocks 1 to 3. It is possible to assemble a structure such as a pyramid-like pyramid structure using blocks made from the pieces provided on the sheet 100 for making a block tool. Using the blocks made from the sheet 100 for making a block tool, structures of various shapes, not limited to pyramid structures, can be assembled. Regardless of the example of the sheet 100 for making a block tool shown in FIG. 1(a), the sheet 100 for making a block tool can arbitrarily select various combinations of pieces of various types and numbers. The sheet 100 for making a block tool may include only the first piece 11 and the second piece 12 if a structure can be assembled using only the first and second blocks 1 and 2. The sheet 100 for making a block tool may include the first to fourth pieces 11 to 14 when a structure can be assembled using only the first to fourth blocks 1 to 4. The sheet 100 for making a block tool may include the first piece 11, the second piece 12, and the fourth piece 14 when a structure can be assembled using only the first and second blocks 1, 2, and the fourth block 4. The sheet 100 for making a block tool may include the first piece 11, the second piece 12, and the fifth piece 15 when a structure can be assembled using only the first and second blocks 1, 2, and the fifth block 5. The sheet 100 for making a block tool may include the first piece 11, the second piece 12, and the third and fifth pieces 13, 15 when a structure can be assembled using only the first and second blocks 1, 2, and the third and fifth blocks 3, 5. The sheet 100 for creating assembled block tools may include a first piece 11, a second piece 12 and a fourth and fifth pieces 14, 15, if it is possible to assemble a structure using only the first and second blocks 1, 2 and the fourth and fifth blocks 4, 5.

[0026] As shown in Fig. 1(b), the first piece 11 to the fifth piece 15 have cutting lines 21 for cutting out the outlines of the pieces on the surfaces that will be the back sides when the pieces are made three-dimensional, and folding lines 22 for folding at the edges that are the boundaries between the faces of the blocks. The cutting lines 21 and the folding lines 22 are distinguished from each other, for example, by solid lines and dotted lines. The first piece 11 to the fifth piece 15 may have letters, symbols, figures, patterns, colors, and various other information on the surfaces that will be the front sides when the pieces are made three-dimensional.

[0027] The material of the sheet 100 for making assembled block tools is not particularly limited as long as it can be cut along the contour of each piece and folded to assemble into a three-dimensional shape. Preferably, the sheet 100 for making assembled block tools may be a sheet made of flat paper or resin having a thickness strong enough for assembly. The individual pieces of the sheet 100 for making assembled block tools are cut along the cut lines 21, which are the contours of each piece, using tools such as scissors or a cutter and a writing pad. The cut lines 21, which are the contours of each piece, may be perforated, which are continuous small holes, so that the pieces can be easily separated by hand. When cutting and joining the individual pieces to create a three-dimensional object, the joining can be done by applying adhesive or by using tape as appropriate. Each piece may have a margin for gluing. When assembling the pieces, the places where the pieces are joined, the number of places where the pieces are joined, the ratio of the area of ​​the joined parts, etc. can be selected arbitrarily.

[0028] Fig. 2 shows three examples of the first piece 11 showing the development of the first block 1. The first piece 11 shown in Fig. 1 is just one example, and the first piece 11 may have another shape as long as it can be made three-dimensional to form the first block 1 as shown in Fig. 2. Similarly, the second piece 12 to the fifth piece 15 shown in Fig. 1 are just one example, and the second piece 12 to the fifth piece 15 may have another shape as long as it is a development that can be made three-dimensional to form the second block 2 to the fifth block 5.

[0029] As shown in Fig. 3, the sheet 100 for making assembled block tools further includes a sixth piece 16, which is a development of a tray 6 for placing blocks thereon. The sixth piece 16 includes a placement surface 60 and a protruding wall 61. The shape of the placement surface 60 of the sixth piece 16 can be changed as desired to match the shape of the bottom surface of the structure formed by stacking the blocks. On the placement surface 60 of the sixth piece 16, an equilateral triangle, which is the smallest unit of a block face, may be represented as a reference line for the arrangement (not shown).

[0030] As shown in Figures 4(a) and (b), the sheet 100 for making assembled block tools further includes a seventh piece 17 which is an expanded view of a small capsule 8 for covering each block. The small capsules 8 cover the surface of each block. The small capsules 8 are removably attached to the blocks. The small capsules 8 may cover at least one surface of a block in a structure in which blocks are stacked. As shown in Figure (b), the small capsules 8 may cover three sides of the block. The area ratio of each side of the seventh piece 17 can be selected arbitrarily so that the small capsules 8 do not easily come off the blocks when covering each block.

[0031] The surface of the small capsules 8 may display words, letters, symbols, figures, patterns, and various information in various countries, such as Japanese, English, and Chinese. When such information is provided in the small capsules 8, the information is printed, written by hand, or attached with a sticker. Various information created by the user can be displayed on the surface of a structure formed by stacking blocks using the small capsules 8. In addition, even after the structure is completed by stacking blocks, the small capsules 8 can be placed on the surface of the blocks, so that letters, symbols, figures, patterns, etc. can be placed in the position intended by the user. Furthermore, by replacing the small capsules 8 from the surface of the blocks, information such as letters, symbols, figures, patterns, etc. can be updated.

[0032] As shown in Figs. 5(a) and (b), the sheet 100 for making assembled block tools further includes an eighth piece 18 which is a development of a capsule 9 for covering a structure formed by stacking blocks. As shown in Fig. 5(b), the capsule 9 may have substantially the same shape as the structure and cover the surface of the structure except for the bottom surface. The capsule 9 may cover the entire structure. The capsule 9 may be a cube or a sphere, etc., as long as it can cover the entire structure. In this embodiment, the capsule 9 has substantially the same shape as the pyramidal structure formed by stacking blocks and covers the surface of the pyramidal structure except for the bottom surface. The color of the capsule 9 is arbitrary, but it is preferable that the color is transparent so that letters, symbols, figures, patterns, etc., shown on the surface of the structure can be identified.

[0033] The interlocking block tool assembly kit 200 may at least include the interlocking block tool creation sheet 100 that includes pieces corresponding to the number of blocks that constitute a structure formed by stacking blocks. The interlocking block tool creation sheet 100 may include all the pieces required on one sheet. The interlocking block tool creation sheet 100 may include the pieces required divided across multiple sheets. The interlocking block tool assembly kit 200 may include cutting tools such as scissors and cutters for processing the pieces, and a writing pad, etc. The interlocking block tool assembly kit 200 may include adhesives, tapes, etc. for joining the pieces. (Embodiment 2)

[0034] A second embodiment of the present invention will be described. In the second embodiment, only configurations different from those included in the first embodiment described above will be described. All of the configurations described in the first embodiment can be included in the second embodiment. The definitions of the terms described in the first embodiment are also the same in the second embodiment.

[0035] As shown in FIG. 6(a), each block further includes a connecting piece portion 24a and a connecting opening portion 24b. The blocks can be detachably connected to each other by inserting the connecting piece portion 24a provided on one block into the connecting opening portion 24b of the other block. The connecting piece portion 24a has a shape that protrudes from the equilateral triangular surface of the smallest unit of the block to the outside of the block. The connecting opening portion 24b is an opening provided on the equilateral triangular surface of the smallest unit of the block. The connecting opening portion 24b has a shape that allows the connecting piece portion 24a to be detachably attached, and is a shape that allows the blocks to be connected to each other in a state in which the connecting piece portion 24a of one block is inserted into the connecting opening portion 24b of the other block. The width w1 of the connecting piece portion 24a is shorter than the width w2 of the connecting opening portion 24b to such an extent that the connecting piece portion 24a can be detachably attached to the connecting opening portion 24b. The shape of the connecting piece portion 24a can be selected to be approximately triangular, approximately rectangular, or any other shape, regardless of the semicircular shape shown in FIG. 6(a). The shape of the connecting opening 24b may be an ellipse, a line, or any other shape, instead of the approximate rectangle shown in FIG. 6(a).

[0036] As shown in Figs. 6(b) and (c), each piece for a block further includes a cut guide line 23 on the surface that will be the back side when the block is made into a three-dimensional shape. The cut guide line 23 includes a connecting piece guide line 23a and a connecting opening guide line 23b. A pair of connecting piece portions 24a and connecting opening portions 24b are formed from the connecting piece guide line 23a formed on the cut guide line 23 of one piece and the connecting opening guide line 23b provided on the cut guide line 23 of the other piece to be connected. When connecting blocks to each other, a connecting piece portion 24a is provided in one block, and a connecting opening portion 24b to which the connecting piece portion 24a can be attached and detached is provided in the other block.

[0037] FIG. 6(b) is an example of the incision guide line 23. As shown in FIG. 6(b), the incision guide line 23 is composed of a circle formed inside an equilateral triangle constituting a piece and a line connecting two points on the circumference of the circle. The center of the circle constituting the incision guide line 23 is the same as the center of the equilateral triangle which is the smallest unit of the block. The connecting piece portion 24a is a protruding piece formed by cutting the connecting piece portion guide line 23a which is an arc of the circle constituting the incision guide line 23 and bending the chord of the arc which is the connecting piece portion guide line 23a in a mountain fold. The range in which the connecting piece portion guide line 23a is cut is within a central angle of about 120 degrees or more and about 180 degrees or less. The connecting piece portion 24a of this embodiment is a semicircle with a central angle of 180 degrees. It is desirable that the diameter of the circle forming the connecting piece portion 24a is about 30% or more and about 80% or less of the diameter of the circle inscribed in the equilateral triangle which is the smallest unit of the block. This is because if the connecting piece portion 24a is relatively small compared to the surface to be connected, the connecting piece portion 24a may easily come off the connecting opening portion 24b, making it difficult to maintain the connected state.

[0038] The connecting opening 24b is formed along the connecting opening guide line 23b, which is a line connecting two points on the circumference of the circle constituting the incision guide line 23. The connecting opening 24b of this embodiment has a width that allows the semicircular connecting piece portion 24a to be attached and detached, so it is formed along the diameter of the circle constituting the incision guide line 23. The connecting opening 24b of this embodiment is an opening into which the semicircular protruding piece that forms the connecting piece portion 24a can be inserted. The connecting opening 24b of this embodiment is a substantially rectangular shape formed along the connecting opening guide line 23b. Regardless of the shape of the connecting opening 24b of this embodiment, the connecting opening 24b can be arbitrarily selected as long as it is a linear, elliptical, or other opening into which the connecting piece portion 24a can be inserted.

[0039] It is desirable that the longitudinal width of the connecting opening 24b in this embodiment is about 30% to about 80% of the diameter of the circle inscribed in the equilateral triangle, which is the smallest unit of the block. If the connecting opening 24b is relatively small compared to the connecting surface, the connecting piece 24a may easily come off the connecting opening 24b, making it difficult to maintain the connected state. In this embodiment, as shown in FIG. 6(b), the connecting opening guide line 23b is shown as three lines parallel to each side of the equilateral triangle, which is the smallest unit of the block. In this way, the blocks can be connected to each other from three directions. Regardless of the three lines representing the connecting opening guide line 23b, the connecting opening 23b can be selected arbitrarily as long as the connecting piece 24a can be inserted.

[0040] FIG. 6(c) is another example of the incision guide line 23. As shown in FIG. 6(c), the incision guide line 23 is composed of an equilateral triangle and a line passing through the center of the equilateral triangle and parallel to the three sides of the equilateral triangle, which is the smallest unit of the block. The equilateral triangle constituting the incision guide line 23 is inscribed in the inscribed circle of the equilateral triangle, which is the smallest unit of the block. The center of the equilateral triangle constituting the incision guide line 23 is the same as the center of the equilateral triangle, which is the smallest unit of the block. The connecting piece portion 24a is a protruding piece formed by cutting the connecting piece portion guide line 23a on two sides of the equilateral triangle constituting the incision guide line 23 into a Λ-shape and folding the base of the Λ-shaped connecting piece portion guide line 23a in a mountain fold. The connecting piece portion 24a of this embodiment is a protruding piece of an equilateral triangle whose base is a line passing through the center of the equilateral triangle constituting the incision guide line 23 and parallel to the sides of the equilateral triangle, which is the smallest unit of the block. The length of the side of the equilateral triangle forming the connecting piece 24a in this embodiment is preferably about 30% to about 80% of the diameter of the circle inscribed in the equilateral triangle, which is the smallest unit of the block. This is because if the connecting piece 24a is relatively small compared to the surface to be connected, the connecting piece 24a may easily come off the connecting opening 24b, making it difficult to maintain the connected state.

[0041] The connecting opening 24b is formed on the connecting opening guide line 23b, which is a line that passes through the center of the equilateral triangle constituting the incision guide line 23, connects points on two sides of the equilateral triangle that is the smallest unit of the block, and is parallel to the sides of the equilateral triangle. The connecting opening 24b in this embodiment is an opening into which the equilateral triangular protrusion that forms the connecting piece portion 24a can be inserted. The opening is a substantially rectangular shape that has sides longer than the length of the sides of the equilateral triangle and can be detachably inserted. Regardless of the shape of the connecting opening 24b in this embodiment, the connecting opening 24b can be arbitrarily selected as long as it is a linear, elliptical, or other opening into which the connecting piece portion 24a can be inserted. The connecting opening 24b of one block corresponding to the connecting piece portion 24a of the other block is provided at a position corresponding to the base of a triangle with the connecting piece portion 24a as two sides. It is desirable that the longitudinal width of the connecting opening 24b is greater than the length and width of the base of a triangle with the connecting piece portion 24a as two sides.

[0042] It is desirable that the width of the connecting opening 24b in this embodiment is about 30% or more and about 80% or less of the diameter of the circle inscribed in the equilateral triangle, which is the smallest unit of the block. If the connecting piece portion 24a is relatively small compared to the surface to be connected, the connecting piece portion 24a may easily come off the connecting opening 24b and it may be difficult to maintain the connected state. In this embodiment, as shown in FIG. 6(c), three lines parallel to each side of the equilateral triangle, which is the smallest unit of the block, are the connecting opening guide lines 23b. In this way, the blocks to be connected from three directions can be connected to each other. Regardless of the three dotted lines representing the connecting opening guide lines 23b, the connecting opening 24b can be selected arbitrarily as long as the connecting piece portion 24a can be inserted.

[0043] In this embodiment, the small capsules 8 cover the surfaces of each block except for the connecting piece portion 24a and the periphery of the connecting opening 24b. In one example, the small capsules 8 cover the entire block, and when the block has a connecting opening 24b, the small capsules 8 have connecting openings 24b of approximately the same shape. When the block to be covered by the small capsule 8 has a connecting piece portion 24a, the connecting piece portion 24a of the block is inserted into the connecting opening 24b of the small capsule 8, and when the block has a connecting opening 24b, the connecting piece portion 24a of the block to be connected to the block is inserted into the connecting opening 24b of the small capsule 8.

[0044] In this embodiment, a cut guide line 23 may be provided on the placement surface 60 of the tray 6. The cut guide line 23 may be detachable from a connecting piece portion 23a or a connecting opening portion 24b provided on the block.

[0045] Next, the function of the above-mentioned sheet 100 for making assembled blocks will be described.

[0046] By using the assembly block tool making sheet 100, it is possible to make each of the three-dimensional blocks, trays 6, small capsules 8, and capsules 9 from a flat surface, and the process of making a three-dimensional object from a flat sheet promotes the improvement of spatial recognition and three-dimensional recognition of children and other players. By assembling not only simple shaped three-dimensional objects but also complex shaped three-dimensional objects, the simplicity of the assembly process is eliminated. Therefore, more thinking is required and it becomes more interesting. As a result, children and other players are less likely to become bored, and it becomes a desirable intellectual toy or educational toy. When the sheet only includes the first piece 11 and the second piece 12, and the third to fifth pieces 13 to 15 are used, children who have difficulty making three-dimensional blocks can play with this assembled block tool making sheet 100. Depending on whether or not all or some of the third to fifth pieces 13 to 15 are used, it is possible to use it in a way that corresponds to the intellectual development level of the children or other players.

[0047] The small capsules 8 are attached to the surface of each block after the blocks are stacked to form a structure, so that the words, letters, symbols, figures, patterns, and various information displayed on the surface of the small capsules 8 can be oriented in a direction that is easy for viewers of the structure to see.

[0048] Usually, the uses of a structure completed by stacking blocks are limited, so the completed structure is often not actively used. Even after the structure is completed, new information can be displayed on the surface of the blocks at any time by combining and placing words, letters, symbols, figures, patterns, and various information shown in the small capsules 8 on the surface of the structure, thereby demonstrating originality and ingenuity. The structure can be enjoyed not only during the process of creating the structure, but also after completion, and can be used for various games. As a result, children and other players are less likely to become bored with the toy, making it a desirable intellectual or educational toy.

[0049] The capsule 9 can stably maintain the completed shape of the stacked blocks, is impact resistant, and is maintained as an integral unit so that it does not separate even when the stack is carried by hand. Also, if there is a gap between the capsule 9 that covers the structure and the structure, even if the blocks that make up the structure collapse due to impact or the like, the collapsed blocks will fit inside the capsule 9, making it easy to handle.

[0050] The connecting piece portion 24a and the connecting opening portion 24b are detachably connected, so that the blocks are not fixed and can be removed, and there is an advantage that various types of blocks can be easily combined. In addition, the stacked shape of the blocks can be stably maintained, and the stacked structure is difficult to separate even when transported, and is easily maintained as a whole. Since multiple blocks can be combined and connected to each other, a new structure can be created as a whole. In the second embodiment, the direction of the connecting piece portion 24a and the connecting opening portion 24b can be adjusted along the cutting guide line 23, and the blocks can be easily connected to each other.

[0051] As described above, by assembling the pieces which are the development diagrams of the blocks, tray 6, small capsules 8, and capsules 9 which make up the structure and arranging them on a block tool making sheet 100, the structure becomes lighter, more compact, and easier to handle than conventional three-dimensional block toys.

[0052] (Assembly blocks) Next, the above-mentioned assembly block will be described.

[0053] The assembled block tool A shown in FIG. 7 includes a plurality of first to fifth blocks 1 to 5 and a tray 6. The assembled block tool A shown in FIG.

[0054] The first block 1 is a regular triangular pyramid (regular tetrahedron), and each of the multiple first blocks 1 has the same size. The other second to fifth blocks 2 to 5 also have the same size among the blocks of the same type. The second block 2 is a regular octahedron (regular quadrangular pyramid), and one side surface 20 of this regular octahedron is a regular triangle congruent with one side surface 10 of the first block 1. This second block 2 is useful for filling spaces that cannot be filled appropriately with the first block 1 or the third to fifth blocks 3 to 5 (for example, the space between two surfaces 55a and 55b shown in FIG. 10(a)) when forming the pyramidal structure 7 described later.

[0055] The third to fifth blocks 3-5 correspond to specific examples of the additional block according to the present invention. As shown in Fig. 8, the third block 3 is a parallelepiped, and each side surface 30 is a rhombus formed by connecting two equilateral triangles (congruent with the equilateral triangle of the side surface 10) corresponding to one side surface 10 of the first block 1. The dashed dotted lines in Fig. 8 indicate the portions corresponding to the sides of the equilateral triangles (this also applies to Figs. 9 and 10).

[0056] As shown in Fig. 9, the fourth block 4 is a hexahedron, and each of the front surface 40a and the bottom surface 40b is a trapezoid formed by connecting three equilateral triangles corresponding to one side surface 10 of the first block 1. Each of the rear surface 40c and the top surface 40d is an equilateral triangle congruent with the equilateral triangle, and each of the left and right side surfaces 40e, 40f is a rhombus formed by connecting two of the equilateral triangles. The front surface 40a and the rear surface 40c, and the top surface 40d and the bottom surface 40b are parallel to each other. The left and right side surfaces 40e, 40f are non-parallel to each other.

[0057] As shown in FIG. 10, the fifth block 5 is a nine-sided body, and as shown in FIG. 10(b), the fifth block 5 is formed by assembling one equilateral triangular pyramid 5b to the main part 5a. The main part 5a is substantially the same in shape and size as the fourth block 4, and corresponds to the fourth block 4 turned upside down in FIG. 10. The equilateral triangular pyramid 5b is the same in shape and size as the first block 1, and is assembled to the center of the top surface 50a of the main part 5a (corresponding to the bottom surface 40b of the fourth block 4). Of course, the fifth block 5 has a shape similar to that of the main part 5a and the equilateral triangular pyramid 5b combined, and can be configured as an integrally molded whole. The position of the equilateral triangular pyramid 5b can be other than the center of the top surface 50a of the main part 5a.

[0058] 7, the tray 6 has a mounting surface 60 (upper surface) on which the first to fifth blocks 1 to 5 are placed. A protruding wall 61 in the shape of a loop and having an equilateral triangular shape in plan view is provided on the periphery of the mounting surface 60 and protruding upward from the mounting surface 60. The length of one side of the protruding wall 61 is, for example, six times the length of one side of the first block 1, and the size is such that a total of six first blocks 1 can be arranged in a row along the inside of one side of the protruding wall 61. Of course, the specific size of the tray 6 is not limited to this.

[0059] The number of the first to fifth blocks 1-5 is set to a number that allows a pyramidal structure 7, which is a regular triangular pyramid whose base follows the protruding wall 61, to be properly assembled inside the protruding wall 61 of the tray 6, as shown in Fig. 7(c). In this embodiment, the number of the first and second blocks 1, 2 is set to a number that allows a pyramidal structure 7 to be properly assembled even when only the first and second blocks 1, 2 are used without using any of the third to fifth blocks 3-5.

[0060] In this embodiment, when it is possible to assemble a triangular pyramidal structure using only first blocks 1 and second blocks 2, the number of first blocks 1 and second blocks 2 is expressed by the following formula. The number of first blocks 1 required to assemble a triangular pyramidal structure with x levels (x=1, 2, 3,...n) is a, and the number of second blocks 2 required to assemble a triangular pyramidal structure with x levels (x=1, 2, 3,...n) is b. When the number of levels of a triangular pyramidal structure made by stacking blocks increases to 1, 2, 3, 4, 5, 6..., the number a of first blocks 1 increases in a sequence of 1, 4, 11, 24, 45, 76.... Similarly, the number b of second blocks 2 increases in a sequence of 0, 1, 4, 10, 20, 35.... The numbers a and b of blocks required to assemble a triangular pyramidal structure with x levels (x=1, 2, 3,...n) are expressed by a=x×(x 2 +2)÷3, b=x×(x 2 This can be calculated using the formula: x -1)÷6. Once the number of stages x of the triangular pyramid structure made by stacking blocks is determined from this formula, the required number of first blocks 1 and second blocks 2 can be calculated. Since the number of first blocks 1 and second blocks 2 required to assemble x stages of a triangular pyramid structure can be known in advance, it is possible to provide only the number of first pieces 1 and second pieces 2 required to assemble x stages of a triangular pyramid structure in the assembly block tool creating sheet 100.

[0061] Next, the function of the above-mentioned assembly block A will be described.

[0062] First, by using a plurality of the first to fifth blocks 1 to 5, it is possible to build a pyramidal structure 7 as shown in FIG. 7(c). However, when building the pyramidal structure 7, the third to fifth blocks 3 to 5 have a somewhat complicated shape compared to the first and second blocks 1 and 2. Therefore, compared to the case where only the first and second blocks 1 and 2 are used, for example, the simplicity of building the pyramidal structure 7 is eliminated, and the variations in the way the blocks are combined are substantially increased. This requires more thinking skills and makes it more interesting. As a result, children and other players are less likely to get bored, and it is preferable as an intellectual toy or an educational toy.

[0063] On the other hand, in this embodiment, as described above, it is possible to assemble the pyramidal structure 7 using only the first and second blocks 1, 2, without using the third to fifth blocks 3-5. Therefore, when the third to fifth blocks 3-5 are used, even children who have difficulty assembling the pyramidal structure 7 can play with this assembly block tool A. Depending on whether or not all or some of the third to fifth blocks 3-5 are used, it is possible to use the assembly block tool A in a manner that corresponds to the intellectual development level of the player.

[0064] The protruding wall 61 of the tray 6 serves to determine the position of the bottom block when assembling the pyramidal structure 7. This makes it possible to prevent the blocks constituting the pyramidal structure 7 from collapsing during or after the pyramidal structure 7 is completed. In addition, when assembling the pyramidal structure 7 for the first time, it is advantageous in that the player can easily guess the size of the pyramidal structure 7 that will ultimately be assembled based on the size of the protruding wall 61. After the pyramidal structure 7 is completed, the pyramidal structure 7 can also be lifted by lifting the tray 6. This makes it convenient to move and transport the pyramidal structure 7.

[0065] 11 to 13 show another embodiment of the present invention. In these figures, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as those in the above embodiment.

[0066] In the embodiment shown in FIG. 11, the outer surfaces of the first to fifth blocks 1 to 5 are each color-coded, for example, in three colors (in the drawing, the different colors are represented by patterns). This color coding is done with an equilateral triangle having the same shape and size as one side surface 10 of the first block 1 as the smallest unit. Therefore, of the first to fifth blocks 1 to 5, the side surfaces (including the front, top, bottom, etc.) corresponding to the equilateral triangle of the smallest unit are entirely colored in a single color. The side surfaces larger than the equilateral triangle of the smallest unit may be entirely colored in a single color, or may be colored in two or three colors.

[0067] According to this embodiment, when the pyramidal structures 7 are assembled, it is possible to realize a case where the colors are not uniform as shown in FIG. 12(a), and a case where the sides of the pyramidal structures 7 are the same color and the colors of the sides are different from each other as shown in FIG. 12(b). Compared with the case where the colors are irregular as shown in FIG. 12(a), in the case of FIG. 12(b), it is necessary to give regularity to the colors and to pay attention to the orientation of the first to fifth blocks 1 to 5. Therefore, depending on whether the pyramidal structures 7 of FIG. 12(a) or (b) are the target to be assembled, the required thinking ability differs, which makes it more interesting. In addition, it is possible to widen the range of ages that can be accommodated.

[0068] 13, the second block 2' is a regular square pyramid. This regular square pyramid has one side that is an equilateral triangle congruent with one side of the first block 1, and corresponds to a shape obtained by dividing the regular octahedral second block 2 of the above embodiment into two, top and bottom.

[0069] In this embodiment, similarly to the case where the regular octahedral second block 2 is used, the first to fifth blocks 1, 2' to 5 can be used to assemble the pyramidal structure 7. In addition, since the bottom surface of the regular square pyramid second block 2' is flat and the angles of the four corners are 90 degrees, it is possible to assemble a regular square pyramidal structure (not shown) by placing four second blocks 2' at the four corners of the lowest layer. Therefore, it is possible to assemble both regular triangular pyramids and regular square pyramids, and it is possible to expand the range of play. The tray 6 can be configured to include two types of trays, one for regular triangular pyramids and one for regular square pyramids. The tray for regular square pyramids may have a protruding wall 61 formed in a square loop shape in a plan view. Although omitted in FIG. 13, in this embodiment, as in the embodiment shown in FIG. 11 and FIG. 12, it is of course possible to configure the side surfaces of each block to be color-coded.

[0070] The present invention is not limited to the above-described embodiment, and the specific configuration of each part of the assembly block according to the present invention can be freely modified in various ways within the intended scope of the present invention.

[0071] In the above-described embodiment, the third to fifth blocks 3 to 5 are used as the "additional blocks" of the present invention, but instead, the configuration may include only one type of block or only two types of blocks among the third to fifth blocks 3 to 5. Although it is preferable to use a plurality of additional blocks, the number of the additional blocks may be one or more, and even if a plurality of additional blocks is not used, the technical scope of the present invention is included. In the present invention, a configuration in which blocks other than the third to fifth blocks of the present invention are further provided as additional blocks may also be used.

[0072] The pyramidal structures to be assembled are not limited to equilateral triangular pyramids or equilateral square pyramids, and may be other pyramidal shapes. The specific sizes of the blocks and pyramidal structures are also not particularly limited. The pyramidal structures may be, for example, about 20 to 30 cm in height, or may be as large as 50 cm or over 1 m. A configuration without a tray is also possible. [Explanation of symbols]
