Description

[Technical Field]

[0001] The present invention relates to a slide puzzle tool for use with a slide puzzle in which the direction of the designs displayed on the puzzle pieces can be changed. [Background technology]

[0002] Brain training is said to improve learning ability. Specific benefits include improving children's abilities, preventing brain aging, and preventing dementia. Research conducted by a research institute has shown that people who regularly engage in brain-training puzzles, such as slide puzzles, have better attention, reasoning, and memory.

[0003] Patent Document 1 proposes a sliding block puzzle consisting of a hexagonal board with edges to prevent the pieces from falling off, and triangular or hexagonal pieces whose corners can be moved within the board. This is a sliding block puzzle with the addition of a piece rotation function.

[0004] Patent document 2 proposes a puzzle game in which the pieces are made into regular hexahedrons, allowing six different pictures or letters to be printed on each piece, and by providing a waiting area for one piece on each of the opposite sides of a pair of box frames, it is possible to form the completed design into a square. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 7-275514 [Patent Document 2] Utility model registration No. 3070718 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the puzzle proposed in Patent Document 1, to arrange triangular pieces on the board, it is necessary to arrange the triangular pieces in a predetermined pattern. Furthermore, to arrange hexagonal pieces on the board, all six sides must be in contact with other pieces. In other words, the process of arranging the pieces is more complicated than the process of arranging square pieces on a square board. Furthermore, to rotate a piece, it is necessary to rotate the piece while pressing the rounded corners against other pieces, which makes the operation complicated. Thus, if the operation is too complicated and the difficulty is too high, there is a problem that players may become reluctant to play the puzzle at all.

[0007] The puzzle proposed in Patent Document 2 requires players to align the orientation of the designs on the pieces before starting the puzzle. If players cannot easily arrange the pieces before starting the puzzle, they may be hesitant to play the puzzle at all.

[0008] The present invention was made with an eye on these problems, and aims to provide a slide puzzle tool that allows puzzle pieces to be easily arranged before starting and allows the level of difficulty to be changed. [Means for solving the problem]

[0009] The invention to solve the above problem is a sliding puzzle tool comprising a puzzle area having a plurality of small compartments defined by being divided into a plurality of rows and a plurality of columns, the same number of puzzle pieces as the number of small compartments that can be accommodated in each of the small compartments, and a direction change area connected to the puzzle area, capable of accommodating puzzle pieces and changing the orientation of the patterns drawn on the puzzle pieces; the direction of the patterns arranged in irregular orientations can be aligned in the direction change area, and by repeating the procedure of moving the puzzle pieces using the empty spaces in the small compartments created by the puzzle pieces being accommodated in the direction change area, the patterns can work together to reproduce an intended pattern.

[0010] This configuration allows players to connect to the puzzle area, store puzzle pieces, and change the direction of the designs on the puzzle pieces, eliminating the need to align the designs and place the puzzle pieces in the puzzle area before starting. Players can simply change the direction of the puzzle pieces in the direction change area and align the designs, just like with conventional slide puzzles. Because the puzzle pieces can be easily placed, players can easily start preparing for the slide puzzle without hesitation.

[0011] Preferably, the pattern has a first pattern drawn on a first side of the puzzle piece, and the direction change area has a passage section connected to the small section through which the puzzle piece can move, and a retreat section and a rotation section connected to the passage section, the retreat section being capable of accommodating the puzzle piece, and the rotation section being capable of rotating the first pattern.

[0012] According to this configuration, the orientation of the first symbol can be aligned by repeating the procedure of rotating the other puzzle pieces while the puzzle pieces are stored in the shelter.

[0013] Preferably, the rotating part has an axis located at the center of rotation, and the puzzle pieces are characterized by being provided with a passing recess that allows them to pass through the axis without contacting the second surface opposite the first surface, and a rotating recess that is supported by the axis.

[0014] According to this configuration, the rotating part has an axis located at the center of rotation, and the puzzle pieces are provided with a passing recess that allows them to pass through the axis without contacting the second surface opposite the first surface, and a rotating recess that is supported by the axis, so that the puzzle pieces can rotate smoothly around the rotation center while housed in the rotating part.

[0015] Preferably, the puzzle pieces can move along the passageway with part or all of each of the opposing sides of the puzzle pieces in contact with the passageway.

[0016] With this configuration, the puzzle pieces can move along the passage with all or part of each of their opposing sides in contact with the passage, so that the free rotation of the puzzle pieces is restricted as they move along the passage. In other words, the puzzle pieces pass through the passage in a unique position.

[0017] Preferably, the design comprises a first design drawn on a first face of the puzzle piece and a second design drawn on a second face opposite the first face and which is a design obtained by rotating the first design by 90 degrees, the direction change area comprises a passageway section through which the puzzle piece can move and a reversal section connected to the passageway section, one end of the passageway section is connected to a small section and the other end is connected to a small section different from the small section connected to the one end, when the puzzle piece moves from one end to the other end or from the other end to the one end the design rotates by 180 degrees, and when the puzzle piece is accommodated in the reversal section the puzzle piece is induced to reverse so that its front and back can be reversed.

[0018] With this configuration, the design can be rotated 180 degrees by moving the puzzle piece from one end of the passage to the other. Furthermore, the design can be rotated either clockwise or counterclockwise by moving the puzzle piece from one end to the inversion section, inverting it, and then moving it to one end or the other. By appropriately repeating this operation, the orientation of the design can be aligned. In other words, even if the puzzle piece is placed in the puzzle area with either the first design or the second design facing up, the orientation of the design can be aligned by appropriately repeating the above-described operation.

[0019] Preferably, the passage is defined by an outer boundary and an inner boundary, and the puzzle pieces can move along the passage while contacting the outer boundary and the inner boundary.

[0020] According to this configuration, the passage is defined by an outer boundary and an inner boundary, and the puzzle pieces can move through the passage while being in contact with the outer boundary and the inner boundary, so that when the puzzle pieces move through the passage, the free rotation of the puzzle pieces is restricted. When the puzzle pieces pass through the passage, the rotation of the puzzle pieces is restricted at the passing position.

[0021] Preferably, the reversing portion is characterized by being provided with a reversing slope for guiding the reversal of the puzzle piece.

[0022] According to this configuration, the reversing section is provided with a reversing slope for guiding the reversal of the puzzle piece, so that the puzzle piece can be easily reversed.

[0023] Preferably, the design is recognizable by the indentations carved into the puzzle pieces.

[0024] With this configuration, the designs can be recognized by the indentations engraved on the puzzle pieces, so even visually impaired people can enjoy the slide puzzle by touching and checking the designs with their fingertips. [Brief explanation of the drawings]

FIG. 10(b) to (d) are cross-sectional views taken along the arrow BB in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, a first embodiment of the sliding puzzle tool 1 will be described in detail with reference to FIGS.

[0027] As shown in FIGS. 1(a) and 1(b), the sliding puzzle tool 1 (hereinafter referred to as the sliding puzzle 1) includes a frame 10 that defines a puzzle area R1 and a direction change area R2, and nine puzzle pieces 30. The puzzle area R1 and the direction change area R2 are located on the same plane, lower than the outer area R3. That is, each area is defined by being recessed from the outer area R3. The puzzle area R1 has nine small square sections R11, which are arranged in three rows and three columns. Furthermore, nine puzzle pieces 30 are arranged in each of the small sections R11. In this embodiment, the small sections R11 are arranged in three rows and three columns, but the number of rows and columns may be plural. That is, the number may be two rows and two columns, or three rows and three columns or more. The number of rows and columns does not have to be the same.

[0028] The direction change area R2 has a passageway R21, a rotational section R22, and a waiting section R23. The passageway R21 is a passageway for moving puzzle pieces 30 out of the puzzle area R1 and returning the moved puzzle pieces 30 to the puzzle area R1, and is connected to the small section R11 located in the first row and second column. Note that the connection position is not limited to the small section R11 located in the first row and second column. The width of the passageway R21 is set to be the same as the length of one side of the small section R11. As a result, the puzzle pieces 30 move through the passageway R21 with the opposing sides in contact with the boundary of the passageway R21.

[0029] The rotation section R22 is an area for rotating the puzzle piece 30, and is defined by an arc shape connected to the end of the passage section R21. The axis 15 is attached at the position of the rotation center O1. The diameter of the circle is set to be the same as or slightly longer than the length of the diagonal of the puzzle piece 30. The rotation center O1 is located at the center of the arc circle that defines the rotation section R22.

[0030] The waiting section R23 is an area where puzzle pieces 30 are temporarily stored, and is connected to the middle of the passage section R21. It is preferable that the shape of the waiting section R23 is such that puzzle pieces 30 can be placed without shifting, and that other puzzle pieces 30 can pass through the passage section R21 while placed therein.

[0031] The puzzle pieces 30 are square flat plates in plan view, and nine puzzle pieces 30 are arranged in a puzzle area R1 having nine small sections R11. One of the numbers 1 to 9 is engraved on the first surface S1 as patterns 31 to 39 (see Figure 2(a)). That is, in the patterns 31 to 39, the numbers are recessed from the surrounding area. Since the patterns 31 to 39 can be recognized by touching the unevenness with the fingers, even people with visual impairments can enjoy this slide puzzle 1.

[0032] As shown in FIG. 2(b), the second surface S2 has a passage recess 41 and a rotation recess 42. The passage recess 41 is a groove that is cross-shaped in a plan view and connects the centers of the opposing sides of the puzzle piece 30. The depth of the groove is set deeper than the height of the axis 15. The rotation recess 42 is a groove that is provided at a position where the cross-shaped grooves intersect. The depth of the rotation recess 42 matches the height of the axis 15. As a result, when the puzzle piece 30 passes through the passage portion R21 and reaches the rotation portion R22, the axis 15 passes through the rotation recess 42 and moves along the passage, and the rotation recess 42 is supported by the axis 15. When a rotation force is applied to the puzzle piece 30 in this state, the puzzle piece 30 rotates around the axis 15.

[0033] When the puzzle pieces 30 are randomly arranged in the small section R11 without aligning the orientation of the designs 31 to 39, a procedure for rearranging the puzzle pieces 30 to recreate an expected pattern will be described.

[0034] As a first step, the randomly arranged patterns 31 to 39 are aligned in the same direction. As an example, the procedure for aligning pattern 35 drawn on the panel piece located in row 1, column 3 shown in Figure 3(a) to the same direction as pattern 31 drawn on the panel piece located in row 1, column 1 will be described. Pattern 35 is rotated 90 degrees counterclockwise relative to pattern 31.

[0035] The puzzle pieces 30 arranged in one row and two columns are moved to the waiting section R23 via the passage section R21 and are then retracted. As a result, the small section R11 located in the first row and second column becomes a so-called empty space EP, where no puzzle pieces 30 are placed. The puzzle pieces 30 carrying the design 35 are then moved to the empty space EP and the passage section R21 to the rotating section R22. At this time, the passing recess 41 passes through the axis 15. Because the depth of the passing recess 41 is set deeper than the height of the axis 15, the puzzle pieces 30 can move along the rotating section R22 without coming into contact with the axis 15. When the puzzle pieces 30 contact the edge of the rotating section R22, the rotating recess 42 is supported by the axis 15. As shown in FIG. 3(b), the puzzle pieces 30 are rotated 90° clockwise around the axis 15. As a result, the design 35 faces the same direction as the design 31. 3(c), the puzzle piece 30 is then placed through the passage R21 into the empty space EP located at row 1, column 2. At this time, the small section R11 at row 1, column 3 is in the empty space EP state.

[0036] By using the empty spaces EP to move the puzzle pieces 30 placed in the puzzle area R1, the puzzle pieces 30 with different pattern directions are moved to the small section R11 with one row and two columns. The movement of the puzzle pieces 30 with different pattern directions is possible by using the empty spaces EP to sequentially move the puzzle pieces 30 placed in the puzzle area R1. The directions of the puzzle pieces 30 with different pattern directions can be aligned using the same procedure as described above.

[0037] After aligning the direction of the symbols on all puzzle pieces 30, the puzzle pieces 30 arranged in one row and two columns according to the expected pattern are retreated to the retreat section R23. In the first embodiment, these are the puzzle pieces 30 that display symbols 32. Using the empty spaces EP created by the movement of the puzzle pieces 30, the puzzle pieces 30 are moved one by one, and other puzzle pieces 30 are placed in their designated positions. Then, the puzzle pieces 30 that were retreated to the retreat section R23 are moved to the small section R11 located in the one row and two columns. This allows the symbols to work together to recreate the expected pattern.

[0038] In the first embodiment, one evacuation section R23 is provided, but two or more may be provided. The passage section R21 may be extended to be used as the second evacuation section R23. Increasing the number of puzzle pieces 30 that can be evacuated simplifies the game. The expected pattern to be reproduced is exemplified as one in which the numbers 1 to 9 are arranged in order in the row direction as shown in FIG. 1, but it may also be one in which the sum of the numbers in each row and column is the same. These can be decided appropriately before starting the puzzle.

[0039] The designs are numbers 1 to 9, but are not limited to this. For example, they may be part of a landscape, a person's face, fruit, or part of a tool.

[0040] Embodiment 2 will be described in detail with reference to Figures 4 to 9. Since Embodiment 1 and Embodiment 2 have some common configurations, the following mainly describes the different configurations. Furthermore, the same reference numerals are used for the same configurations as in Embodiment 1, and reference numerals in the 200s are used for the different configurations.

[0041] As shown in FIG. 4, the sliding puzzle tool 201 includes a frame 210 that defines a puzzle area R1 and a direction change area R202, and nine puzzle pieces 230.

[0042] The direction change area R202 has a passage R221 and a reversing section R222. The passage R221 is a passage for moving the puzzle pieces 230 out of the puzzle area R1 and for evacuating the puzzle pieces 230, and one end of the passage R221 is connected to the small section R11 located in the first row and first column, and the other end of the passage R221 is connected to the small section R11 located in the first row and third column.

[0043] The passage portion R221 is an annular passage defined by an outer peripheral boundary 225 and an inner peripheral boundary 226.

[0044] The outer boundary 225 is a boundary that coincides with a part of a circle that is centered at point P and passes through the connection points C1 and C2. Point P is located at a position shifted from the center of the small section R11 located in row 1, column 2 by the length of the side of the small section R11 in the direction of the inverted section R222. The inner boundary 226 is composed of a lower boundary 226a and an upper boundary 226b, and the upper boundary 226b is part of a circle that is centered at point P and has a diameter equal to the length of one side of the small section R11. The lower boundary 226a is a straight line that extends from the opposing side of the small section R11 located in row 1, column 2 and is tangent to the above-mentioned circle. This allows the puzzle piece 230 to move along the passage section R221 while maintaining a unique posture (see Figure 5).

[0045] A reversing section R222 is provided near the apex of the passage section R221. The reversing section R222 is shaped so that it can accommodate a puzzle piece 230 and allow other puzzle pieces 230 to pass through the passage section R221 while the puzzle piece 230 is accommodated. A reversing slope S222 is also provided at the top end to guide the reversal of the puzzle piece 230 accommodated therein. As shown in FIG. 6 , the reversing slope S222 is an inclined path that slopes upward in the direction away from the passage section R221. By moving the puzzle piece 230 in the upward direction, a gap is created between a part of the puzzle piece 230 and the frame body 210. By using this gap as a clue to grasp the puzzle piece 230, the first side S1 and the second side S2 of the puzzle piece 230 can be easily reversed.

[0046] As shown in Figure 7(a), the puzzle piece 230 is a square flat plate in a plan view, and each puzzle piece has a first design 231a-239a engraved on its first surface S1. The first design 231a-239a is one of the numbers 1-9. The last digit of the first design corresponds to the engraved number.

[0047] As shown in Figure 7(b), second symbols 231b to 239b are engraved on the second surface S2 opposite to the first surface S1. The second symbols 231b to 239b have the same numbers as the first symbols 231a to 239a, rotated 90 degrees counterclockwise.

[0048] The procedure for rearranging the puzzle pieces 230 to recreate the expected pattern will now be described.

[0049] The puzzle pieces 230 are randomly placed in the puzzle area R1. At this time, it is not necessary to align the orientation of the designs. The first surface S1 may be the front surface, or the second surface S2 may be the front surface. When the first surface S1 is the front surface, the design on the second surface S2 located on the back surface is the design on the first surface S1 rotated 90 degrees counterclockwise. When the second surface S2 is the front surface, the design on the first surface S1 located on the back surface is the design on the second surface S2 rotated 90 degrees clockwise.

[0050] When the puzzle pieces 230 are randomly arranged, the patterns that appear on the surface will be in four directions: the normal direction, a direction rotated 180 degrees, a direction rotated 90 degrees clockwise, and a direction rotated 90 degrees counterclockwise. In the first stage, the patterns that were randomly arranged in the puzzle area R1 are aligned to the normal direction.

[0051] The first pattern 235a in the direction rotated by 180 degrees can be made to face in the normal direction by moving from one end of the passage portion R221 to the other end, as shown in FIG.

[0052] The procedure for aligning the orientation of symbols rotated 90° clockwise and counterclockwise will be described using FIGS. 9(a) to 9(d) as examples. Puzzle pieces 230 are arranged in one row and three columns so that the first symbol 231a displayed on the first side S1 is visible. As shown in FIG. 9(a), the first symbol 231a is rotated 90° counterclockwise relative to the aligning direction, and the second symbol 231b displayed on the second side S2 is rotated 90° counterclockwise from the first symbol 231a. As shown in FIG. 9(b), when the puzzle piece 230 is moved counterclockwise along the passage R221, the first symbol 231a is rotated 180° from the aligning direction at a position adjacent to the inverted portion R222. As shown in FIG. 9(c), if the puzzle piece 230 is flipped over using the flip slope S222, the second face S2 becomes the front, and the clockwise rotated second symbol 231b becomes visible. As shown in FIG. 9(d), the second symbol 231b is aligned in the desired direction by moving the puzzle piece counterclockwise along the passage. As described above, to align the symbols rotated 90° clockwise or counterclockwise, the puzzle piece 230 is moved to the flip section R222 via the passage R221, and the puzzle piece 230 is flipped over at the flip section R222. The puzzle piece 230 can then be returned to its original position or moved toward the end opposite its original position to return it to its normal orientation.

[0053] A modified example of the reversing portion R222 will be described with reference to Figures 10(a) to 10(d). This modified example is composed of a reversing slope S222-1, a continuous surface S222-2 continuing from the reversing slope S222-1, a slope R227 continuing from the continuous surface S222-2, and a reversing recess R228 continuing from the slope R227. This takes into consideration the possibility that the puzzle piece 230 may get caught on the frame 210 in the second embodiment. When the puzzle piece 230 is pushed into the reversing recess R228, the puzzle piece 230 tilts and moves away from the reversing slope S222-1. This allows the puzzle piece 230 to be easily turned over.

[0054] By increasing the number of puzzle pieces to 12, the scope of use can be expanded. For example, it can be used as a slide puzzle to arrange the zodiac calendar (Japanese month names, birthstones, birth flowers, birth birds, birth constellations, etc.) in a predetermined order. It can also be used as a slide puzzle to complete haiku. Specifically, the first five characters of the verse are displayed, and the player must complete the middle seven characters and the last five characters. This makes it more accessible to older adults and expands its application to the educational field. Furthermore, the game can begin with a 12-word chain game, and the 12 pieces can be created using the words from that chain. This allows for interaction with young children. For example, by selecting 12 distinctive words that reveal the story of a folk tale or monster tale, the story is displayed when the puzzle is completed, providing a sense of accomplishment. This can also be applied to events such as festivals, exhibitions, and weddings.

[0055] At least one puzzle piece 230 is retracted into the passage section R221 to provide a void space EP in the puzzle area R1. The retracted puzzle pieces 230 are arranged in a one row, one column, or one row, three columns pattern.

[0056] The puzzle pieces 230 placed in the puzzle area R1 are moved using the empty spaces EP to recreate the expected predetermined pattern. After that, the retreated puzzle pieces 230 are moved back into the puzzle area R1.

[0057] The difficulty level of the slide puzzle can be lowered by increasing the number of retracted puzzle pieces 230. In this embodiment 2, it is possible to contrast a total of three puzzle pieces 230, two in the passage section R221 and one in the reversal section R222. [Industrial Applicability]

[0058] The slide puzzle tool of the present invention allows users to start the slide puzzle easily without any resistance, and the difficulty level of the puzzle can be changed. In addition, even visually impaired people can play the puzzle, so it has great industrial applicability. [Explanation of symbols]
