Description

  The present invention relates to a puzzle toy that is played for the purpose of moving a plurality of pieces one by one and matching the arrangement to a predetermined arrangement.

  Conventionally, a puzzle toy called a sliding block puzzle is known. Generally speaking, there are various types of sliding block puzzles, but in particular, one of the 16 pieces arranged in 4 rows and 4 columns is removed from the case to provide a section (blank) where no pieces exist. In addition, after arranging the remaining 15 pieces in random order, the pieces adjacent to the blank are moved to the blank one after another, and the arrangement of the pieces is changed to match the predetermined arrangement. “15 games” to play as a purpose are famous (for example, Patent Documents 1 to 7).

  In “15 games”, different numbers and parts of pictures are written on the top of each piece, and the pieces are moved using the numbers and pictures as a guide. In this type of sliding block puzzle, any piece adjacent to the blank can be moved to the blank. However, the “15 game” has a problem that there are many pieces of paths (solutions) until a plurality of pieces are matched with the target arrangement, so that they can be solved easily. Hereinafter, a sliding block puzzle in which a piece can be freely moved, such as “15 games”, may be referred to as a “free movement type sliding block puzzle”. Free-moving sliding block puzzles such as “15 games” can be easily arranged without using too many heads until the number of remaining pieces is two or three, regardless of the total number of pieces. Thus, the remaining two or three frames can be easily arranged by operating only some of the frames around the remaining frames.

  Also, so far, the size of each piece can be changed by changing the size of each piece, and even if a piece adjacent to a piece is blank, the piece cannot be moved to the blank. A sliding block puzzle in which such a situation occurs has also been proposed (for example, Patent Documents 8 and 9). For example, if a square piece occupying a total of 1 section of 1 row and 1 column and a vertically long piece occupying 2 sections of 2 rows and 1 column are mixed, they are adjacent to the left and right (row direction and horizontal direction) of the square piece. When there is a blank for one section in the section, the piece can be moved to the blank, but even if there is a blank for one section in the section adjacent to the left and right of the vertically long piece, the piece Cannot be moved to the blank because it is caught by another piece. In this way, by limiting the movement of the pieces, the number of pieces of routes until the puzzle is solved can be reduced. Hereinafter, the sliding block puzzle in which the movement of the piece is restricted may be referred to as a “restricted moving type sliding block puzzle”. One of the limited movement type sliding block puzzles is the “boxed daughter” who plays with the purpose of moving several large pieces occupying two or more sections and moving one of them from the starting point to the goal point. .

  However, the conventional limited movement type sliding block puzzle typified by "Daughter in a box" has a large piece that occupies two or more sections, so when trying to move the piece with a width of two or more sections, It was necessary to provide two or more blanks. For this reason, compared with the case where a blank is provided with only one section, there is a drawback that the degree of freedom of movement of a small piece that occupies only one section is increased. For this reason, the conventional limited movement type sliding block puzzle cannot always be said to reduce the number of pieces of routes until the puzzle is solved. In addition, even if the number of paths of the pieces until the puzzle is solved decreases, the number of pieces decreases compared to the free-moving sliding block puzzle when compared with the same number of sections, so that the puzzle may not always be difficult. Was not limited. In addition, the limited movement type sliding block puzzle has fewer variations in the arrangement of the pieces than the free movement type sliding block puzzle, and because there are few combinations of the initial arrangement of the pieces that can be formed as a puzzle and the arrangement at the time of completion, it becomes bored. There was also a drawback that it was easy.

  The present invention has been made in order to solve the above-described problems, and is a conventional free-moving sliding block puzzle that can freely move a piece, and although the movement of the piece is limited, the size of the piece varies. Therefore, it is intended to provide a puzzle toy that can be enjoyed with more difficult and deeper puzzles than the conventional limited movement type sliding block puzzle, which has few variations in moving pieces. Specifically, even when using the head from the movement of the first piece and the remaining steps are a few, not only some of the pieces around the remaining pieces, The main purpose is to provide a puzzle toy that cannot be cleared without operating any piece.

The above issues
Multiple pieces,
Piece arrangement means having a plurality of sections for two-dimensionally arranging a plurality of pieces;
Consisting of
At least one section of the plurality of sections in the piece arrangement means is a blank without a piece,
A puzzle toy intended to match the arrangement of a plurality of pieces to a predetermined arrangement by sliding the pieces one after another from a section adjacent to the blank,
Each piece is
A display layer displaying appearance elements that characterize the piece,
A base layer for positioning the piece at a normal position in the section by contacting another piece adjacent to the piece, or piece arrangement means;
With
At least one piece is a lock-type piece including a lock layer having a lock projection protruding outward from the outer periphery of the base layer of the piece,
Even when there is a blank adjacent to a certain lock-type piece, the locking convex portion of the lock-type piece interferes with other pieces or piece arrangement means existing in other sections adjacent to the blank. Thus, the present invention is solved by providing a puzzle toy characterized in that a situation in which the lock-type piece cannot be moved to the normal position of the blank occurs.

  Here, “two-dimensional arrangement” in the description “arranging a plurality of pieces two-dimensionally” means that a plurality of pieces are arranged so that there are two degrees of freedom for moving the pieces, The concept is not necessarily limited to a case where a plurality of pieces are arranged on a plane, but a concept including a case where a plurality of pieces are arranged on a curved surface. For example, as shown in FIG. 21, the piece arrangement means has a columnar shape, a plurality of pieces are arranged on the outer peripheral surface (cylindrical surface) of the piece arrangement means, and each piece is placed on the central axis of the piece arrangement means. It is possible to move in the direction (degree of freedom 1) and the rotational direction (degree of freedom 1) with the central axis as the rotation axis, and each piece has 2 degrees of freedom. The pieces move on the curved surface, and such an arrangement of pieces is also included in the concept of “two-dimensional arrangement”.

  In addition, the “appearance element” in the description “appearance element characterizing the piece” means a character, figure, color, shape, or the like that can be visually recognized by human eyes. The “appearance element” may be a combination of two or more elements selected from characters, figures, colors, shapes, and the like. Among these, “character” is a concept including not only general characters but also symbols such as “=” and “&”. In addition, it is assumed that the “graphic” is a concept including not only simple things represented by lines and patterns but also complicated things such as paintings and photographs. Further, “color” is a concept including colorless and transparent, white color, and the like. Furthermore, the “shape” is a concept including not only a planar shape but also a three-dimensional shape. In the puzzle toy of the present invention, the arrangement of a plurality of pieces is matched to the arrangement of predetermined pieces using the appearance elements in the display layer of each piece as a clue.

  Furthermore, “characterizing the piece” in the description “appearance element characterizing the piece” does not mean that the appearance elements of all the pieces are different. That is, even if there are two or more pieces having the same appearance element (indistinguishable pieces), if there are other pieces having appearance elements different from the two pieces, It is included in the concept of “appearance element characterizing a piece”. In other words, if there are at least two types of appearance elements of a plurality of pieces, they are included in the concept of “appearance elements characterizing the piece”.

  As a result, each piece has a substantially similar size that occupies only one section of the piece arrangement means, and the movement of the pieces is restricted while using approximately the same number of pieces as the pieces in the piece arrangement means. Is possible. Therefore, it is possible to enjoy a complicated and difficult puzzle having both the number of pieces in the conventional free movement type sliding block puzzle and the restriction of the movement of the piece in the conventional limited movement type sliding block puzzle.

  By the way, the puzzle toy of the present invention is not limited to a hardware toy that can be directly touched by hand. In other words, the technical scope of the puzzle toy of the present invention includes the above-described software representation of the plurality of pieces and piece arrangement means. For example, a computer programmed to display the puzzle toy of the present invention on a screen of a display means such as a liquid crystal monitor and to operate the puzzle toy on the screen with an input means such as a keyboard, a mouse or a controller, or the program A stored recording medium such as a CD-ROM is also included in the technical scope of the puzzle toy of the present invention.

  As described above, according to the present invention, a conventional free-moving sliding block puzzle in which a piece can be moved freely, or a conventional piece that varies in size and has little variation in movement of the piece although movement of the piece is limited. It is possible to provide a puzzle toy that can enjoy a deeper and more difficult puzzle than the limited moving type sliding block puzzle. For example, using the head from the first move of the first piece, even in the final stage when the remaining pieces are a few pieces, not only some of the pieces around the remaining pieces but also the whole piece It is also possible to provide a puzzle toy that cannot be cleared without operation.

0. Outline of Puzzle Toy A preferred embodiment of the puzzle toy of the present invention will be described more specifically with reference to the drawings. In the following, five types of puzzle toys of the first embodiment, the second embodiment, the third embodiment, the fourth embodiment and the fifth embodiment will be described, but the puzzle toy of the present invention has these embodiments. However, the present invention is not limited to this, and can be changed as appropriate without departing from the spirit of the present invention.

1. First, the puzzle toy according to the first embodiment will be described. 1-17 is the figure which showed the puzzle toy of the 1st embodiment. As shown in FIG. 1, the puzzle toy according to the first embodiment has a plurality of pieces and a plurality of sections (parts separated by a one-dot chain line in FIG. 3) in which these pieces are two-dimensionally arranged. And means. At least one section among the plurality of sections in the piece arrangement means is a blank with no pieces. The puzzle toy according to the first embodiment is a puzzle toy intended to match the arrangement of a plurality of pieces to a predetermined arrangement by sliding pieces one after another from a section adjacent to the blank to the blank.

  FIGS. 1 and 2 show a state when the puzzle is cleared in which pieces “1” to “15” are arranged in ascending order from the upper left corner of the piece arrangement means to the lower right corner. That is, from this state, the game is played for the purpose of returning to the arrangement shown in FIGS. 1 and 2 again after breaking the arrangement of the pieces into an irregular order. However, the clearing condition of the puzzle toy of the first embodiment is not limited to this. For example, other arrangements such as arranging the frames “1” to “15” in descending order may be used as the clearing condition. Moreover, since the movement of a piece is restrict | limited as the puzzle toy of 1st embodiment is mentioned later, a specific piece (for example, "1" piece) is taken from a starting point (for example, division of the 1st row 1st column). Just moving to the goal point (for example, the 4th row and 4th column section) requires a considerable amount of work, and you can experience the difficulties that you could not have experienced with a conventional free-moving sliding block puzzle.

  The piece arrangement means is not particularly limited as long as it has a plurality of sections. In the puzzle toy according to the first embodiment, as the piece arrangement means, as shown in FIG. 3, a piece constituted by a bottom plate and a peripheral frame rising upward from the entire outer peripheral portion of the bottom plate is used. The shape of the bottom plate and the peripheral frame is not particularly limited because it varies depending on the shape of the piece. However, the plan view shape of the bottom plate and the peripheral frame is generally substantially the same as the shape formed by two-dimensionally spreading the plan view shape (outer peripheral shape) of the base portion of the piece. As the shape of the base portion of each piece in plan view, a shape that can be laid out two-dimensionally simply by translating it is adopted. Specific examples include parallelograms (including squares, rectangles, and diamonds). In the puzzle toy of the first embodiment, the shape of the base portion of each piece in plan view is a square as shown in FIG. On the other hand, the plan view shape (outer peripheral shape) of the bottom plate of the piece arrangement means and the plan view shape (outer peripheral shape and inner peripheral shape) of the peripheral frame are also square.

  The number of sections in the piece arrangement means is not particularly limited as long as it is plural. However, if the number of sections is reduced too much, the number of pieces used is also reduced, and the puzzle becomes easier. For this reason, the number of sections in the piece arrangement means is usually 9 (3 rows and 3 columns) or more. The number of sections is preferably 12 (3 rows and 4 columns) or more, and more preferably 16 (4 rows and 4 columns) or more. On the other hand, as the number of sections in the piece arrangement means increases, the difficulty of the puzzle increases. For this reason, from the viewpoint of increasing the difficulty level of the puzzle, there is no particularly preferable value for the upper limit of the number of sections. For example, if the number of sections is increased to 3000 (50 rows and 60 columns, etc.), 2000 (40 rows and 50 columns, etc.), 1000 (10 rows and 10 columns, etc.), the enjoyment as a jigsaw puzzle is also added. However, in this case, it becomes impossible to carry the puzzle toy easily. In order to make the puzzle so large that it can be easily carried, the number of sections is normally set to 400 or less (20 rows and 20 columns, etc.). The number of partitions is preferably 225 or less (15 rows and 15 columns, etc.), and more preferably 100 (10 rows and 10 columns, etc.) or less. In the puzzle toy of the first embodiment, as shown in FIG. 2, the sections in the piece arrangement means are 4 rows and 4 columns, and the number thereof is 16.

  The number of blanks on which the pieces can be slid (matches the value obtained by subtracting the total number of pieces from the number of sections of the piece arrangement means) is not particularly limited as long as it is one or more. The number of blanks is appropriately changed according to the number of sections in the piece arrangement means, the desired difficulty level of the puzzle, and the like. However, if the number of blanks is increased too much, the puzzle becomes simple and the significance of adopting the configuration of the present invention decreases. For this reason, the number of blanks is usually one. In the example of FIG. 2, one section in the fourth row and the fourth column is blank. In the puzzle toy according to the first embodiment, the number of pieces corresponds to a value obtained by subtracting the number of blanks from the total number of sections of the piece arrangement means. In the puzzle toy of the first embodiment, 15 pieces “1” to “15” are used.

  Moreover, in the puzzle toy of the first embodiment, each piece is composed of a display layer, a lock layer, and a base layer, as shown in FIGS. In the puzzle toy of the first embodiment, all the pieces are provided with a lock layer, and all the pieces are lock-type pieces. On the display layer of these frames, appearance elements that characterize the frames are displayed. The place where the display layer is provided is not particularly limited and may be provided on the side of the piece or the like, but is usually provided in a place where the user of the puzzle toy is easily visible. Considering this, in the puzzle toy of the first embodiment, a display layer is provided on the upper surface of the lock layer, which is the uppermost part of the piece. Different numbers (“1” to “15”) are displayed on the display layers of the different frames so that all of the 15 frames can be identified.

  The shape of the base layer is common to all pieces. The base layer contacts the outer peripheral portion of the base layer in another piece adjacent to the one piece having the base layer, or the inner peripheral portion of the peripheral frame in the piece arranging means, thereby causing the one piece to move. It has the function of positioning at the normal position of the section in the piece arrangement means (position where the outer peripheral portion of the base layer overlaps the boundary line of the section). The base layer also has a function of maintaining the lock layer at a certain height. In the puzzle toy according to the first embodiment, the base layer has a square shape in plan view as described above, and has a rectangular parallelepiped shape as a whole.

  The shape of the lock layer is not common to all the pieces, and there are a plurality of types. The lock layer has a function of restricting movement of the one piece by interfering with a lock layer of another piece adjacent to the one piece having the lock layer or a peripheral frame in the piece arrangement means. As shown in FIGS. 4 to 11, the lock layer of each piece is provided with a locking convex portion protruding outward from the outer periphery of the base layer. In the puzzle toy of the first embodiment, there are four types of pieces depending on the protruding direction of the locking convex portion.

  That is, as shown in FIG. 4 and FIG. 5, a “downward protruding type piece” in which the locking convex portion protrudes below the base layer (downward when facing the number displayed on the display layer). As shown in FIGS. 6 and 7, the right protrusion type piece with the locking projection protruding to the right of the base layer (right when facing the number displayed on the display layer). 8 and FIG. 9, “an upwardly protruding type piece” in which the locking convex portion protrudes above the base layer (upward when facing the number displayed on the display layer). 10 and 11, as shown in FIGS. 10 and 11, the locking protrusion protrudes to the left of the base layer (left when facing the number displayed on the display layer). There are four types of “pieces”.

  In the puzzle toy of the first embodiment, as shown in FIG. 12, the “1” piece, the “3” piece, the “6” piece, and the “8” piece are downward projecting type pieces. , “2”, “5” and “10” are right-projecting type pieces, “9”, “11”, “13” and “15”. "4", "7", "12" and "14" are left-projecting type pieces.

  Thus, there are the following reasons for using four types of pieces. That is, as shown in FIG. 13, when an upwardly projecting type “9” piece is to be arranged in the upper adjacent section of the downwardly projecting type “1” piece, the locking projections of the mutual pieces Will not interfere with each other. For this reason, if the upper adjacent section of the downward projecting type piece is a blank, the upper projecting type piece may move from any section adjacent to the blank to the normal position of the blank. it can. The same applies to an attempt to place a "2" piece that is a right-projection type or a "4" piece that is a left-projection type in a section adjacent to the top of the "1" piece that is a downward projection type. In addition, when a downward projecting type piece other than “1” (for example, “3” piece) is to be placed in the upper adjacent section of the downward projecting type “1” piece, the “3” piece The projecting part for locking in is projected on the base of the piece of “1”, but the projecting part is released by the recess for relief formed on the base of “1”. It does not interfere with the lock layer of the piece. For this reason, the downward protruding type piece can also be arranged in the upper adjacent section of the downward protruding type piece.

  As shown in FIG. 14, even when an upward protruding type “9” piece is to be arranged in a section adjacent to the left of the downward protruding type “1” piece, the locking protrusions of each piece Does not interfere. For this reason, when the section on the left side of the downward projecting type piece is a blank, the upward projecting type piece may move from any section adjacent to the blank to the normal position of the blank. it can. An attempt is made to place a left protruding type “4” piece or a downward protruding type piece other than “1” (for example, “3” piece) in a section adjacent to the left of the downward protruding type “1” piece. The same applies to the case. When an attempt is made to place a right protruding type “2” piece in a section adjacent to the left of a downward protruding type “1” piece, the locking convex portion of the “2” piece is “ The protruding portion protrudes on the base of the “1” piece, but the protruding portion is released by the relief recess formed on the base of “1”, so that it does not interfere with the lock layer of the “1” piece. For this reason, the right protruding type piece can also be arranged in the left adjacent section of the downward protruding type piece.

  Further, as shown in FIG. 15, even when an upwardly protruding type “9” piece is arranged in the right adjacent section of the downwardly protruding type “1” piece, the locking protrusions of the respective pieces are locked. The part does not interfere. For this reason, when the right adjacent section of the downward projecting type piece is a blank, the upward projecting type piece may be moved from any section adjacent to the blank to the normal position of the blank. it can. An attempt was made to place a downward protruding type piece other than “1” (for example, “3” piece) or a right protruding type “2” piece in the right next to the downward protruding type “1” piece. The same applies to the case. In addition, when an attempt is made to place a left protruding type “4” piece in the right adjacent section of a downward protruding type “1” piece, the locking convex portion of the “4” piece is “ The protruding portion protrudes on the base of the “1” piece, but the protruding portion is released by the relief recess formed on the base of “1”, so that it does not interfere with the lock layer of the “1” piece. For this reason, the left protruding type piece can also be arranged in the left adjacent section of the downward protruding type piece.

  On the other hand, as shown in FIG. 16 and FIG. 17, when the “9” piece of the upward projecting type is arranged in the lower adjacent section of the “1” piece of the downward projecting type, The locking projection comes into contact and interferes. For this reason, when the lower adjacent section of the downward projecting type piece is a blank, the upward projecting type piece may move from any section adjacent to the blank to the normal position of the blank. Not possible (movement restriction pattern 1). For the same reason, in the puzzle toy according to the first embodiment, even when the right adjacent section of the right-hand protruding type piece is a blank, the normal position of the blank has any one adjacent to the blank. The left-projecting type piece cannot move from the section (movement restriction pattern 2). In addition, even when the upper adjacent section of the upward protruding type piece is a blank, the downward protruding type piece moves from any of the sections adjacent to the blank to the normal position of the blank. Cannot be performed (movement restriction pattern 3). Furthermore, even if the left adjacent section of the left protruding type piece is a blank, the right protruding type piece is moved from any section adjacent to the blank to the normal position of the blank. Cannot come (movement restriction pattern 4). In the case of other combinations, there is no restriction on the movement of the pieces because the lock layers do not interfere with each other, for example, the locking projections on one piece are guided while being released by the relief depressions on the other piece. Thus, in the puzzle toy of the first embodiment, by using four types of pieces, four kinds of restrictions (movement restriction patterns 1 to 4) are added to the movement of the pieces, and the difficulty level of the puzzle is increased. Yes.

2. Next, the puzzle toy of the second embodiment will be described. FIG. 18 is a perspective view showing a state where the piece “1” in the puzzle toy according to the second embodiment is disassembled. The puzzle toy according to the second embodiment is different from the puzzle toy according to the first embodiment only in the structure of the respective pieces, and other configurations such as the piece arrangement means are the same as those of the puzzle toy according to the first embodiment. Can be used. In addition, since the pieces other than “1” in the puzzle toy according to the second embodiment are the same as the pieces “1” except for the display layer, illustration is omitted.

  In the puzzle toy of the second embodiment, as shown in FIG. 18, the piece has a structure that can be disassembled into a base layer, a lock layer, and a display layer. The base layer is a rectangular parallelepiped in plan view, and two sets of fixing recesses (first fixing recess and second fixing recess) for fixing the lock layer are provided on the upper surface of the base layer. ing. The lock layer has a rectangular parallelepiped shape in plan view, and a set of fixing convex portions is provided on the lower surface thereof. The lock layer is fixed to the base layer by fitting the one set of fixing convex portions into any one of the two fixing concave portions of the base layer. The protruding direction of the lock layer can be changed depending on which fixing concave portion the fixing convex portion is fitted into.

  That is, in the example of FIG. 18, when the fixing convex portion is fitted into the first fixing concave portion, the lock layer can be protruded below the base layer, and the “1” piece is a downward protruding type lock. It can be a pattern piece. In addition, in the example of FIG. 18, when the fixing convex portion is fitted into the second fixing concave portion, the lock layer can be protruded above the base layer, and the piece “1” is an upward protruding type lock. It can be a pattern piece. By the way, after the “1” piece is made to be an upward protruding type or downward protruding type lock type piece, the base layer is rotated 90 ° clockwise or counterclockwise together with the locking layer, and the “1” piece is moved to the right. It can be a side-projection type piece or a left-projection type piece. In the puzzle toy according to the second embodiment, as will be described later, the display layer can be rotated every 90 °. Therefore, even if the base layer is rotated together with the lock layer, characters displayed on the display layer are displayed. It can be adjusted to the correct orientation. The concave-convex relationship between the fixing concave portion of the base layer and the fixing convex portion of the lock layer may be reversed.

  In the puzzle toy according to the second embodiment, since the unevenness is not provided on the side surface of the base layer or the like, all the pieces can be pulled out from the piece arranging means. However, like the puzzle toy of the fifth embodiment to be described later, if the base layer is provided with a drop prevention protrusion or a drop prevention recess so that the pieces are not dropped from the piece arrangement means, the puzzle toy user However, the base layer of the piece cannot be freely changed, and the piece in the puzzle toy according to the second embodiment shown in FIG. 18 can be changed only in two ways of the upward projecting type and the downward projecting type. For this reason, in the case of the piece in the puzzle toy according to the second embodiment, when the base layer is provided with a drop-off preventing convex portion or a drop-off preventing concave portion, the same fixing as the first fixing concave portion and the second fixing concave portion It is preferable to provide a recess (a third fixing recess (not shown) and a fourth fixing recess (not shown) separately in a direction perpendicular to the first fixing recess and the second fixing recess. The lock layer can be fixed at a position rotated by 90 ° with respect to the upper protrusion type, the lower protrusion type, and the left, even if the piece has a drop prevention protrusion or a drop prevention recess. It is possible to change in four ways, a side protrusion type and a right protrusion type, which is also effective when the base layer is not square in plan view.

  The display layer has a square plate shape in plan view, and can be fitted into a display layer fitting recess provided in a horizontal cross-section rectangle on the top surface of the lock layer. For this reason, the display layer can be rotated 360 ° every 90 ° inside the display layer fitting recess, and its center position can be moved within the display layer fitting recess. It is possible to change the direction of the character displayed on the display, or to make the center of the character displayed on the display layer coincide with the center of the frame. At this time, as shown in the example of FIG. 18, if the bottom surface of the display layer fitting recess is colored, it is possible to easily determine in which direction the lock layer of the piece protrudes. In the puzzle toy according to the second embodiment, the display layer may be fixed in a state where it can be rotated at least 90 ° clockwise or counterclockwise with respect to the lock layer. It is not limited to what is shown in FIG. For example, the display layer may have a disc shape, and the display layer insertion recess of the lock layer may have a horizontal circular shape. Further, the fitting structure of the display layer and the lock layer may be reversed (the convex portion provided on the upper surface of the lock layer may be fitted in the concave portion provided on the lower surface of the display layer).

  As described above, in the puzzle toy according to the second embodiment, the base layer, the lock layer, and the display layer in each piece (when there are no top, bottom, left and right appearance elements to be displayed on the display layer, the display layer is particularly It is not necessary to have a separable structure.), The structure can be changed into various forms with one piece. For this reason, the user of the puzzle toy has four types of pieces (upward protruding type lock type piece, downward protruding type lock type piece, left protruding type lock type piece or right protruding type lock type). It is possible to select any one type from among the frames. Therefore, the user of the puzzle toy can change the difficulty level according to his / her preference.

3. Next, the puzzle toy of the third embodiment will be described. FIG. 19 shows that the “1” piece (downward protruding type piece) in the puzzle toy according to the third embodiment has a “9” piece (upward protruding type) from the lower adjacent or left adjacent compartment. It is the top view which showed the state which moved the piece. FIG. 20 shows a “9” piece (upward protruding type piece) from a lower adjacent section of the “1” piece (downward protruding type piece) in the puzzle toy according to the third embodiment. It is the top view which showed the state which moved. In the puzzle toy of the first embodiment, as shown in FIGS. 4 to 11, only the locking convex portion is provided on the lock layer. However, in the puzzle toy according to the third embodiment, as shown in FIGS. 19 and 20, not only the locking convex portion but also the locking convex portion adjacent to the piece is fitted into the lock layer of a certain piece. A recess for locking is also provided. This makes it possible to limit the direction of the piece moving to the blank.

  For example, in FIG. 19, the lock layer of each piece is provided with one lock projection and one lock recess. By doing so, the “1” piece of the downward projecting type is provided. A piece “9”, which is an upward projecting type, can move to the lower adjacent section (blank) only from the left adjacent or lower adjacent section of the blank. Further, in FIG. 20, the lock layer of the “1” piece of the downward projecting type is formed with two locking convex portions and one locking concave portion therebetween, and the upward projecting type of “9” The lock layer of the piece is formed with one lock convex part and two lock concave parts on both sides of the lock layer. By doing in this way, the bottom of the "1" piece that is a downward projecting type is formed. The piece of “9”, which is an upward projecting type, can move to the section (blank) only from the section adjacent to the bottom of the blank. In this way, the puzzle can be made deeper by mixing the pieces with the locking recesses formed in the lock layer.

4). Next, the puzzle toy according to the fourth embodiment will be described. FIG. 21 is a perspective view showing the puzzle toy according to the fourth embodiment. FIG. 22 is a perspective view showing piece arrangement means in the puzzle toy according to the fourth embodiment. In the puzzle toy of the first embodiment, as shown in FIG. 3, the piece arrangement means is composed of a bottom plate and a peripheral frame. However, in the puzzle toy according to the fourth embodiment, as shown in FIG. 22, the piece arrangement means has a drum shape composed of a columnar support drum and a pair of holding plates provided at both ends of the support drum. Has become. As shown in FIG. 21, each piece is formed in a curved shape so that it can follow the outer peripheral surface of the support drum.

  The puzzle toy of the fourth embodiment is similar to the puzzle toy of the first embodiment in that each piece is composed of a base layer, a lock layer, and a display layer. In puzzle toys, it is necessary to devise such that the pieces do not fall off the support drum. For example, as in a puzzle toy according to a fifth embodiment to be described later, a drop-out preventing protrusion (see FIG. 26) protruding from the side surface is provided on the side surface on the common side of the base layer of each piece. A drop-off prevention recess (see FIG. 26) for fitting the drop-off prevention protrusion in the base layer of the adjacent piece is provided on the side surface opposite to the drop-off prevention protrusion in the base layer of the frame. and so on. At this time, as shown in FIG. 22, a locking groove is provided on the inner surface of one holding plate, and a locking projection (not shown) is provided on the inner surface of the other holding plate. The locking groove is fitted with a drop-preventing convex portion on the base layer of the piece arranged at one end of the support drum, and the locking projection is prevented from falling off on the base layer of the piece arranged on the other end of the support drum. Fit into the recess. As a result, it is possible to prevent all pieces from falling off the support drum.

  As described above, in the puzzle toy according to the fourth embodiment, the piece arrangement means has a drum shape, so that each piece can be moved in two degrees of freedom in the outer peripheral direction and the central axis direction of the support drum. it can. In the puzzle toy of the fourth embodiment, unlike the puzzle toy of the first embodiment, each piece has a condition that permits (the lock layer does not interfere with the lock layer of other pieces, and there is a blank in the moving direction). As long as it can be moved indefinitely toward the outer periphery of the drum. Therefore, in the puzzle toy according to the fourth embodiment, it becomes possible to realize a moving path of the pieces that could not be realized with the puzzle toy according to the first embodiment, and the puzzle can be made more interesting.

5. Next, the puzzle toy of the fifth embodiment will be described. FIG. 23 is a perspective view showing the puzzle toy according to the fifth embodiment. FIG. 24 is a plan view showing the puzzle toy according to the fifth embodiment. FIG. 25 is a perspective view showing a plurality of pieces in the puzzle toy according to the fifth embodiment. FIG. 26 is a cross-sectional view showing a state in which the puzzle toy according to the fifth embodiment is cut along a plane that passes through the centers of the pieces “11” to “15” and is perpendicular to the bottom plate of the piece arrangement means. FIG. 27 is an explanatory view showing the arrangement of the pieces in the puzzle toy according to the fifth embodiment. For convenience of illustration, in FIG. 23 and FIG. 25, the characters (numbers) on the display layer of each frame are indicated by circled numbers. However, the piece “25” is a piece for decoration only, and can be pulled upward from the state shown in FIG. The place where there was a piece of “25” is used as a blank.

  In the puzzle toy of the fifth embodiment, as shown in FIG. 23, 25 pieces arranged in 5 rows and 5 columns are made higher from the outer peripheral portion to the center portion of the piece arrangement means, At the time of clearing, the top surface of the piece is made into a pyramid shape. Further, the difference in the shaded hatching of the display layer in FIGS. 23 to 25 represents the difference in color. That is, in the puzzle toy of the fifth embodiment, the appearance elements in the display layer of the pieces display not only numbers (characters) but also their three-dimensional shapes and colors. Thus, by combining a plurality of appearance elements, it becomes possible to further diversify the puzzle clearing conditions. For example, even if the order of numbers is not the same, it is only necessary to have a pyramid shape (for example, a condition that clears even if the arrangement of “6” pieces and “11” pieces in FIG. 23 is reversed). Or, clear conditions (for example, “1” to “5”, “7” to “7” in FIG. 23) that only a certain color (one color, two colors, or three colors) pieces need only be pyramid-shaped. As long as even 9 ”and“ 13 ”pieces form one side of the pyramid, the arrangement of the other pieces is clear even if they are not completed), and the numbers and pyramids are not completed, but even the colors It is also possible to enjoy the puzzle under a clear condition that it should be aligned (for example, a condition that clears even if the arrangement of “14” pieces and “15” pieces in FIG. 23 is reversed).

  Further, in the puzzle toy of the first embodiment, as shown in FIG. 1, only one lock layer is provided for each piece. However, in the puzzle toy of the fifth embodiment, FIG. 25 and FIG. As shown in FIG. 4, a piece having a total of two layers of a first lock layer and a second lock layer is mixed. Of the 24 pieces excluding the “25” piece, 15 pieces (“1” to “6”, “10”, “11”, “11”, 15 ”,“ 16 ”, and“ 20 ”to“ 24 ”) are low in height, and are a single-lock type piece having only one of the first lock layers as the lock layer. In addition, nine pieces ("7" to "9", "12" to "14", and "17" to "19" pieces) arranged inside the lock-type piece when the puzzle is cleared are It is higher than the single-layer lock type piece, and the lock layer is a double-layer lock type piece having two layers of a first lock layer and a second lock layer.

  In each piece, as shown in FIG. 26, the height of the first lock layer and the height of the second lock layer are the same for each layer, and the first lock layer of one piece is the first lock layer of another piece. The second lock layer of one piece interferes with only the second lock layer of another piece. How to project the locking projection (first locking projection) of the first locking layer and how to project the locking projection (second locking projection) of the second locking layer in each piece It becomes possible to restrict the movement of the piece more complicatedly, making the puzzle more difficult and interesting as compared to the puzzle toy of the first embodiment. For reference, FIG. 27 shows forms of the first lock layer and the second lock layer in the pieces “1” to “24”. Since it can be easily inferred from the explanation of the puzzle toy of the first embodiment whether the movement of the piece is restricted in any situation, the explanation is omitted here.

  Furthermore, in the puzzle toy according to the fifth embodiment, as shown in FIG. 26, the piece arrangement means includes a bottom plate, a peripheral wall rising from the outer edge of the bottom plate, and an upper frame projecting inward of the piece arrangement means from above the peripheral wall. And an intermediate plate sandwiched between a part of the upper frame and a part of the peripheral wall. The bottom plate is a square in plan view, and the peripheral wall and the upper frame are also square in plan view along the four sides of the bottom plate, but the middle plate is L-shaped in plan view along only two sides of the bottom plate. It is said that. A common side surface of the base layer of each piece (in the example of FIG. 26, the left side surface toward the paper surface and the back side surface (not shown) toward the paper surface) protrudes from the side surface. A drop-off prevention convex portion is provided, and a side surface on the opposite side to the drop-off prevention convex portion in the base layer of each piece (in the example of FIG. 26, the right side surface toward the paper surface and the front side toward the paper surface. A side surface (not shown) is provided with a drop-out preventing recess for fitting the drop-out preventing projection in the base layer of the adjacent piece.

  As shown in FIG. 26, the inner edge of the middle plate is fitted into the drop-off preventing recess in the base layer of the piece adjacent to the middle plate, and the inner edge of the upper frame facing the middle plate is the same as that of the piece adjacent to the upper frame. The upper surface of the drop-off preventing convex portion in the base layer is suppressed. The drop-off prevention convex part of the piece not adjacent to the upper frame is fitted into the drop-off prevention concave part of another piece adjacent to the piece. Thereby, each piece can be prevented from falling off from the piece arranging means. Therefore, it is possible to prevent the piece from being lost. Also, all the pieces except the “25” pieces that form the blank cannot be pulled out from the piece arrangement means, and the puzzle must be solved without a formal procedure of moving the pieces to the blank. It is also possible to do.

6). Others As described above, the puzzle toy of the present invention has been described by taking the five embodiments from the first embodiment to the fifth embodiment as examples. However, unless the configuration described in one embodiment is impossible, It can also be employed in other embodiments. For example, the lock layer in the puzzle toy piece of the fourth embodiment may have a multilayer structure of a first lock layer and a second lock layer, like the piece lock layer in the puzzle toy of the fifth embodiment. Moreover, the structure which is not demonstrated in the puzzle toy of a 1st embodiment to a 5th embodiment can be employ | adopted with the puzzle toy of this invention. For example, the piece lock layer in the puzzle toy of each embodiment may have a multilayer structure of three or more layers.

7). Applications In addition, the puzzle toys from the first embodiment to the fifth embodiment all have the same size (the number of sections occupied by each piece), but each so-called “boxed daughter” The size of the piece may be changed. For example, a piece that occupies a total of 1 section of 1 row and 1 column, a piece that occupies 2 sections of 1 row and 2 columns, a frame that occupies 2 sections of 2 rows and 1 column, and a total of 4 sections of 2 rows and 2 columns. For example, the occupied pieces are mixed. As a result, it becomes possible to enjoy the difficulty that cannot be experienced with a conventional “boxed daughter”.
