Description

  The present invention relates to a three-dimensional model piece set and a plate-like piece.

  Conventionally, a three-dimensional model assembled by combining a plurality of plate-like pieces is known. The plate-shaped piece used for such a three-dimensional model generally has a locking projection or a locking hole, and the locking projection is inserted into the locking hole of another plate-shaped piece, or this locking. The other plate-like piece is connected to the hole by inserting a locking projection of the other plate-like piece into the hole. When such a plate-like piece is connected to another plate-like piece, it is easy to come off in the direction opposite to the locking direction of the locking projection and the locking hole. For example, it may be necessary to fix the connection part. However, it takes time to apply the adhesive to the connection points. Moreover, if it fixes with an adhesive agent in this way, it will become difficult to cancel | release a connection again after fixation, and there exists a possibility that a plate-shaped piece may be damaged if it tries to release a connection forcibly.

  Further, as such a plate-like piece, for example, as in “Fitting assembly type light emitting model” (see Japanese Patent Application Laid-Open No. 2004-121790), the cut grooves formed in the side edges are engaged with each other to form a plate-like piece. It is also known that pieces are connected to other plate-like pieces by combining the pieces in an intersecting state.

  Since the plate-like piece described in this publication is combined with another plate-like piece by engaging a notch groove formed on the side edge, it is easy to maintain the posture at the time of combination and to enhance the three-dimensional effect. However, even with the plate-like piece described in this publication, there is a high possibility that it will come out in the reverse direction of the combination direction after the combination, and there is a possibility that it will be damaged or lost after falling off.

  This invention is made | formed in view of such a situation, and aims at provision of the three-dimensional model piece set and plate-like piece which can connect a some plate-like piece easily and reliably. .

  The three-dimensional model piece set according to the present invention made to solve the above-mentioned problems is a three-dimensional model piece set including a plurality of plate-shaped pieces combined in an intersecting state to assemble a three-dimensional model, and a pair of the above-mentioned plates Cut grooves that engage with each other at the time of combination are formed on the side edges of each of the shaped pieces, and locking portions that are locked at the time of combination are formed in the cut grooves of the pair of plate-like pieces, respectively. .

  In the three-dimensional model piece set, a pair of plate-shaped pieces each have a cut groove on a side edge, and the pair of plate-shaped pieces are combined in an intersecting state by engaging the cut groove. The shaped pieces are accurately engaged in a fixed posture, and the stereoscopic effect is easily emphasized. Further, since the three-dimensional model piece set has locking portions that are locked when combined, formed in the cut grooves of the pair of plate-shaped pieces, the combination of the pair of plate-shaped pieces enables the locking of these three-dimensional model piece sets. The parts are locked at the same time. Therefore, the three-dimensional model piece set can easily and reliably connect a pair of plate-like pieces.

  When combined, the locking portion of one plate-like piece is locked between the bottom and the locking portion of the cut groove of the other plate-like piece, and the locking portion of the other plate-like piece is one plate It is good to be latched between the bottom part and the latching | locking part of the cut groove | channel of a shape piece. Thereby, a pair of plate-shaped piece can be connected easily and reliably.

  It is good for the to-be-latched part latched by the latching part of one said plate-shaped piece at the time of a combination to be formed on the extended line of the notch groove of the other plate-shaped piece. As described above, the locked portion that is locked to the locking portion of one of the plate-like pieces at the time of combination is formed on the extension line of the cut groove of the other plate-like piece, thereby a pair of plate-like shapes. By combining the pieces, these locking portions and locked portions are locked simultaneously. Therefore, the three-dimensional model piece set can easily and reliably connect a pair of plate-like pieces.

  A second locked portion to be locked to the locking portion of the other plate-like piece may be formed on the extension line of the cut groove in the one plate-like piece on which the locking portion is formed. Thus, the second locked portion to be locked to the locking portion of the other plate-shaped piece is formed on the extension line of the cut groove in the one plate-shaped piece where the locking portion is formed. The locking portion of one plate-shaped piece and the locked portion of the other plate-shaped piece, and the second locked portion of the one plate-shaped piece and the second locking portion of the other plate-shaped piece Can be locked to each other, and the pair of plate-like pieces can be more reliably connected.

  It is good for the said latching | locking part to be a pair of protrusion part extended in the groove | channel formation direction of a pair of side part of the notch groove of a pair of said plate-shaped piece. As described above, the locking portion is a pair of protrusions extending in the groove forming direction of the pair of side portions of the cut groove of the pair of plate-like pieces, thereby making the pair of plate-like pieces easier and more reliable. Can be linked to. Moreover, according to this structure, since a connection of a pair of plate-shaped piece can be cancelled | released comparatively easily, it is excellent also in the removal workability | operativity of a pair of plate-shaped piece after a combination.

  The locked portion may be a locking hole that penetrates in the thickness direction of the other plate-shaped piece. Thus, a pair of plate-shaped pieces can be connected more easily and reliably by the said to-be-latched part being the locking hole penetrated in the thickness direction of said other plate-shaped piece. Moreover, according to this structure, since the connection of the locking part and the locked part can be released relatively easily, the workability of removing the pair of plate-like pieces after combination is excellent.

  The depth direction of the cut groove and the extending direction of the side edge where the cut groove is formed are preferably orthogonal. Thus, by making the depth direction of the cut groove and the extending direction of the side edge where the cut groove is formed perpendicular to each other, it is possible to improve the attachment / detachment workability of the pair of plate-like pieces, and The plate-like pieces can be more firmly connected.

  Moreover, the plate-shaped piece for a three-dimensional model according to the present invention made to solve the above problems constitutes a three-dimensional model piece set that can be combined with other plate-shaped pieces in an intersecting state to assemble a three-dimensional model. A plate-shaped piece for a three-dimensional model, which is formed on the side edge, and is formed on the side groove of the other plate-shaped piece at the time of combination, and is formed in the above-mentioned groove. And an engaging portion capable of engaging other plate-like pieces in the inserted state.

  Since the plate-like piece has a cut groove that engages with a cut groove of another plate-like piece, the cut piece is engaged with the cut groove of another plate-like piece and combined in an intersecting state, While being able to engage with a plate-shaped piece with a fixed posture, it is easy to emphasize the three-dimensional effect. Furthermore, since the said plate-shaped piece is formed in the notch groove, and has the latching | locking part which can latch the other plate-shaped piece of an engagement state, by engaging other plate-shaped piece and the notch groove, The locking portions are locked at the same time. Accordingly, the plate-like piece can be easily and reliably connected to other plate-like pieces.

  It is good to have the to-be-latched part formed on the extended line of the said notch groove, and latched by the other plate-shaped piece of an engagement state. In this manner, the other plate-like piece and the cut groove are engaged with each other by having a locked portion that is formed on the extension line of the cut groove and is locked to the other plate-like piece in the engaged state. Thus, the locking part of the plate-shaped piece is locked to the locked part of the other plate-shaped piece, and the locked part of the plate-shaped piece is locked to the locking part of the other plate-shaped piece. can do. Accordingly, the plate-like piece can be easily and reliably connected to other plate-like pieces.

  As described above, the three-dimensional model piece set and plate-like piece according to the present invention can easily and reliably connect a plurality of plate-like pieces.

Specifically, the plate-like piece set includes a first plate-like piece 1 and a second plate-like piece 2 as the plurality of plate-like pieces.

(Plate-shaped piece)
As shown in FIG. 1B, the first plate-like piece 1 is formed in a plate shape having a substantially uniform thickness. The first plate-like piece 1 has a pair of cut grooves 3 on the same side edge. A pair of locking portions 4 are formed in the pair of cut grooves 3 of the first plate-like piece 1. Further, the first plate-like piece 1 has a pair of second locked portions 5 on an extension line of the pair of cut grooves 3. The side edges where the pair of cut grooves 3 of the first plate-like piece 1 are formed are linear.

  The second plate-like piece 2 has a pair of cut grooves 6 on the same side edge. A pair of second locking portions 7 are formed in the pair of cut grooves 6 of the second plate-like piece 2. The second plate-like piece 2 has a pair of locked portions 8 on the extension line of the pair of cut grooves 3. The shape and forming material of the second plate-like piece 2 are the same as those of the first plate-like piece 1. That is, the pair of cut grooves 6 of the second plate-shaped piece 2 is the same as the pair of cut grooves 3 of the first plate-shaped piece 1, and the pair of second locking portions 7 of the second plate-shaped piece 2 is the first. The pair of latched portions 4 of the plate-like piece 1 are the same as the pair of latched portions 4, and the pair of latched portions 8 of the second plate-like piece 2 are the same as the pair of second latched portions 5 of the first plate-like piece 1. It is said that. Therefore, only the first plate-like piece 1 will be described below, and the description of the second plate-like piece 2 will be omitted. However, in the present embodiment, the first plate-like piece 1 and the second plate-like piece 2 have the same shape and size, but the first plate-like piece 1 and the second plate-like piece 2 are assembled as a three-dimensional model. Different shapes (contours) or sizes may be formed according to the shape, size, or the like.

(First plate-shaped piece)
The material for forming the first plate-shaped piece 1 is not particularly limited as long as it has a rigidity that can maintain the shape and a flexibility that allows the pair of cut grooves 3 to be expanded a little. For example, metal, synthetic resin And rigid materials such as wood phenol, paper phenol, paper epoxy, glass composite, and glass epoxy. Moreover, as a forming material of the 1st plate-shaped piece 1, the foodstuff which has fixed rigidity and flexibility can also be used. Among these, as a material for forming the first plate-like piece 1, a synthetic resin having a certain rigidity and at the same time easily improving flexibility is preferable.

  Examples of the synthetic resin include acrylic resin, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polystyrene, polyolefin, cellulose acetate, and weather resistant vinyl chloride. Among them, an acrylic resin having excellent transparency and appropriate flexibility is preferable.

  As a manufacturing method of the 1st plate-shaped piece 1 using the said synthetic resin, it has the process of shape | molding a plate-shaped object, for example by extrusion molding, and the process of giving the laser processing and forming the shape of each part. The extrusion molding can be performed by, for example, a melt extrusion method. Examples of such a melt extrusion method include a T-die method and an inflation method.

The lower limit of the length L ₁ in the longitudinal direction of the first plate-like piece 1 (the length in the direction of formation of the side edges where the pair of cut grooves 3 are formed) is preferably 0.8 cm, and more preferably 1 cm. On the other hand, the upper limit of the length L ₁ in the longitudinal direction of the first plate-like piece 1 is preferably 20 cm, more preferably 10 cm, and even more preferably 5 cm. If the longitudinal length L ₁ of the first plate-shaped piece 1 is less than the above lower limit, the molding of the first plate-shaped piece 1 may become difficult, a the size of the first plate-shaped piece 1 is too small The combination with the two-plate piece 2 may be difficult. On the contrary, when the length L ₁ in the longitudinal direction of the first plate-like piece 1 exceeds the above upper limit, the size of the first plate-like piece 1 becomes too large, and the combination with the second plate-like piece 2 may be difficult. There is.

The lower limit of the lateral length L _{2 of} the first plate-like piece 1 (the vertical length of the side edges where the pair of cut grooves 3 are formed) is preferably 3 mm, and more preferably 5 mm. On the other hand, the upper limit of the short-side direction length _{L 2} of the first plate-shaped piece 1, 10 cm is preferred, more preferably 5 cm, more preferably 3 cm. If the lateral direction length L ₂ of the first plate-shaped piece 1 is less than the above lower limit, the molding of the first plate-shaped piece 1 may become difficult, the size of the first plate-shaped piece 1 is too small Combination with the second plate-shaped piece 2 may be difficult. Conversely, if the short direction length L ₂ of the first plate-shaped piece 1 exceeds the upper limit, the combination of the second plate-shaped piece 2 becomes difficult size of the first plate-shaped piece 1 is too large There is a fear.

  As a minimum of the thickness of the 1st plate-shaped piece 1, 1 mm is preferable, 1.5 mm is more preferable, and 2 mm is more preferable. On the other hand, the upper limit of the thickness of the first plate-like piece 1 is preferably 4 cm, more preferably 2 cm, and even more preferably 1 cm. When the thickness of the 1st plate-shaped piece 1 is less than the said minimum, while combining with another plate-shaped piece may become difficult, there exists a possibility that it cannot connect with another plate-shaped piece firmly. Conversely, when the thickness of the first plate-like piece 1 exceeds the above upper limit, the size of the first plate-like piece 1 is too large, and the combination work with the second plate-like piece 2 may be difficult.

  The cut groove 3 engages with the cut groove 6 of the second plate-like piece 2 when combined. That is, the cut groove 3 is engaged with the cut groove 6 of the second plate-like piece 2 when combined. The cut groove 3 has a bottom portion 9 and a pair of side portions 10 disposed in parallel to each other. The depth direction of the cut groove 3 is orthogonal to the extending direction of the side edge where the cut groove 3 is formed. The pair of side portions of the cut groove 3 is disposed in parallel with the thickness direction of the first plate-like piece 1. Furthermore, the side edge side end portions of the pair of side portions 10 are chamfered so that the combination work with the second plate-shaped piece 2 is easy.

  The lower limit of the depth of the cut groove 3 is preferably 1.5 mm, more preferably 2 mm, and even more preferably 2.5 mm. On the other hand, the upper limit of the depth of the cut groove 3 is preferably 6 cm, more preferably 3 cm, and even more preferably 2 cm. When the depth of the cut groove 3 is less than the above lower limit, the cut groove 6 of the second plate-shaped piece 2 may not be accurately combined. On the other hand, when the depth of the cut groove 3 exceeds the above upper limit, the size of the first plate-like piece 1 becomes too large, and there is a possibility that the combination with the second plate-like piece 2 becomes difficult.

  The width of the cut groove 3 (distance between the pair of side portions 10 excluding the locking portion 4) is equal to or greater than the thickness of the second plate-like piece 2, and preferably substantially the same as the thickness of the second plate-like piece 2. Is done. As a minimum of the width of cut slot 3, 1 mm is preferred, 1.5 mm is more preferred, and 2 mm is still more preferred. On the other hand, the upper limit of the width of the cut groove 3 is preferably 4 cm, more preferably 2 cm, and even more preferably 1 cm. When the width of the cut groove 3 is less than the above lower limit, the cut groove 6 of the second plate-shaped piece 2 may not be accurately combined. On the other hand, when the width of the cut groove 3 exceeds the above upper limit, the size of the first plate-like piece 1 may become too large, and the combination with the second plate-like piece 2 may be difficult.

The lower limit of the ratio of the depth of the notches 3 for the short direction length L ₂ of the first plate-shaped piece 1, preferably 1/3, 2/5 is more preferable. On the other hand, the upper limit of the ratio of the depth of the notches 3 of the first plate-shaped piece 1 with respect to the lateral direction length L _2, preferably 2/3, 3/5 are more preferred. If the ratio of the depth of the notches 3 for the short direction length L ₂ of the first plate-shaped piece 1 is less than the above lower limit, a possibility that coupling strength in a combined state with the second plate-shaped piece 2 can not be sufficiently obtained There is. Conversely, when the ratio of the depth of the cut groove 3 to the length L ₂ in the short direction of the first plate-like piece 1 exceeds the above upper limit, the strength of the portion on the extension line of the cut groove 3 of the first plate-like piece 1 May decrease, and the first plate-like piece 1 may be easily damaged. As the ratio of the depth of the notches 3 for the short direction length L ₂ of the first plate-shaped piece 1, likely a combination mutual side edges when the second plate-shaped piece 2 is formed flush with 1/2 is particularly preferred.

  The lower limit of the ratio of the depth of the cut groove 3 to the width of the cut groove 3 is preferably 1, more preferably 6/5, and even more preferably 7/5. On the other hand, the upper limit of the ratio of the depth of the cut groove 3 to the width of the cut groove 3 is preferably 5/2, more preferably 2, and even more preferably 9/5. When the ratio of the depth of the cut groove 3 to the width of the cut groove 3 is less than the above lower limit, the connection strength in the state combined with the second plate-like piece 2 may not be sufficiently obtained. On the contrary, when the ratio of the depth of the cut groove 3 to the width of the cut groove 3 exceeds the above upper limit, the size of the first plate-like piece 1 may become too large, or the cut groove 3 of the first plate-like piece 1 and the second There exists a possibility that it may become difficult to combine with the notch groove 6 of the two plate-shaped piece 2.

  The locking part 4 is locked to the locked part 8 of the second plate-shaped piece 2 at the time of combination. Specifically, the locking portion 4 is engaged with the locked portion 8 formed on the extension line of the notch groove 6 in a state where the notch groove 6 of the second plate-like piece 2 is engaged with the notch groove 3. Stopped. The locking portion 4 is formed on the pair of side portions 10 of the cut groove 3. The locking portions 4 are formed as a pair of protrusions that project inwardly from the pair of side portions 10 of the cut groove 3. Specifically, as shown in FIG. 2, the grooves of the pair of side portions 10 of the cut groove 3. It is formed as a pair of protrusions 4a and 4b extending in the forming direction.

  The pair of ridge portions 4 a and 4 b are disposed at positions facing the pair of side portions 10. The pair of protrusions 4a and 4b are formed in an arc shape in cross section in the plane direction. A pair of protrusion parts 4a and 4b latch so that the 2nd plate-shaped piece 2 may be inserted | pinched from both sides so that it may mention later. Therefore, the distance between the top portions of the pair of protruding portions 4 a and 4 b is set to be equal to or less than the thickness of the second plate-shaped piece 2.

  The lower limit of the ratio of the protruding height of the pair of protrusions 4a and 4b to the width of the cut groove 3 is preferably 1/20, and more preferably 1/15. On the other hand, the upper limit of the ratio of the protruding height of the pair of protrusions 4a, 4b to the width of the cut groove 3 is preferably 1/7, and more preferably 1/10. When the ratio of the protruding height of the pair of protrusions 4a, 4b to the width of the cut groove 3 is less than the lower limit, there is a possibility that the locked portion 8 of the second plate-like piece 2 is not accurately locked. Conversely, when the ratio of the protruding height of the first protrusions 4a and 4b to the width of the cut groove 3 exceeds the above upper limit, the cut groove 3 of the first plate piece 1 and the cut groove of the second plate piece 2 6 may be difficult to engage.

  The second locked portion 5 is locked to the second locking portion 7 of the second plate-like piece 2 at the time of combination. Specifically, the second locked portion 5 is formed on the second locking portion 7 formed in the cut groove 6 in a state where the cut groove 6 of the second plate-like piece 2 is engaged with the cut groove 3. Locked. The second locked portion 5 is formed as a locking hole penetrating in the thickness direction of the first plate-like piece 1. The second locked portion 5 is formed in a rectangular cross section whose longitudinal direction is parallel to the bottom portion 9 of the cut groove 3 and whose transverse direction is orthogonal to the longitudinal direction. The length of the second locked portion 5 in the longitudinal direction is equal to or longer than the length of the pair of ridges 4a, 4b, and preferably substantially the same as the length of the pair of ridges 4a, 4b. It is said. When the longitudinal direction length of the 2nd latching | locking part 5 is less than the said minimum, there exists a possibility that it cannot engage with a pair of protrusion part 4a, 4b easily and exactly. On the contrary, when the length of the second locking portion 5 in the longitudinal direction is too long, the engaging portion may rattle when engaged with the pair of protrusions 4a and 4b. Furthermore, the length in the short direction of the second locked portion 5 is equal to or longer than the length in the short direction of the pair of protrusions 4a and 4b, and preferably the length in the short direction of the pair of protrusions 4a and 4b. It is almost the same. When the length in the short direction of the second locked portion 5 is less than the lower limit, there is a possibility that the pair of protruding portions 4a and 4b cannot be easily and accurately engaged. On the contrary, when the length of the second locking portion 5 in the short direction is too long, the engaging portion may be loose when engaged with the pair of protrusions 4a and 4b.

The distance D ₁ of the and the second engaged portion 5 which is formed on an extension of the bottom portion 9 and the cut groove 3 of notches 3, the notches 3 bottom 9 and a pair of protrusions 4a, the 4b there is a distance D ₂ below. The lower limit of the ratio of the distance _{D 2} of the distance _{D 1,} preferably 3/5, more preferably 4/5. If the ratio above distance D ₂ of the distance D ₁ is less than the above lower limit, part strength can not be sufficiently obtained in between the first bottom part 9 of the plate-like piece 1 and the second engaged portion 5, the This part may be easily damaged when combined with the two plate-like pieces 2, and the cut groove 3 of the first plate-like piece 1 in a state where the first plate-like piece 1 and the second plate-like piece 2 are combined. There is a possibility that the play between the bottom 9 and the bottom of the cut groove 6 of the second plate-like piece 2 becomes too large. In contrast, when the ratio with respect to the distance D ₂ of the distance D ₁ is in the above range, while increasing the first bottom part 9 of the plate-like piece 1 an intensity of the portion between the second engaged portion 5, Moderate play between the bottom 9 of the cut groove 3 of the first plate-like piece 1 and the bottom of the cut groove 6 of the second plate-like piece 2 when the first plate-like piece 1 and the second plate-like piece 2 are combined. It is possible to improve the ease of engagement by adjusting. As the ratio of the distance D ₂ of the distance D _1, firmly fix against the first plate-shaped piece bottom 9 of the notches 3 of 1 and the bottom of the second plate-shaped pieces 2 of notches 6 From the point, 1 is preferable.

<Combination procedure>
Next, with reference to FIG.3 and FIG.4, the combination procedure of the 1st plate-shaped piece 1 and the 2nd plate-shaped piece 2 is demonstrated.

  First, as shown to Fig.3 (a), the 1st plate-shaped piece 1 and the 2nd plate-shaped piece 2 are divided into the cut groove 3 of the first plate-shaped piece 1 and the cut groove 6 of the second plate-shaped piece 2. Arrange to face each other in a crossing state.

  Next, as shown in FIG. 3 (b), the first plate-like piece 1 is cut while the cut groove 3 of the first plate-like piece 1 and the cut groove 6 of the second plate-like piece 2 intersect at right angles. The cut groove 6 of the second plate-shaped piece 2 is inserted into the cut groove 3 of the first plate-shaped piece 1 so that the bottom of the second plate-shaped piece 2 is abutted against the bottom 9 of the groove 3. Thereby, a pair of protrusion part 4a, 4b of the 1st plate-shaped piece 1 gets over a pair of protrusion part 7a, 7b of the 2nd plate-shaped piece 2, and the bottom part of the notch groove 6 of the 2nd plate-shaped piece 2 Pushed into the side. At the same time, the pair of protrusions 7a, 7b of the second plate-like piece 2 overcomes the pair of protrusions 4a, 4b of the first plate-like piece 1 and the bottom of the cut groove 3 of the first plate-like piece 1 It is pushed into 9 side. As described above, the width of the cut groove 3 of the first plate-shaped piece 1 is equal to or greater than the thickness of the second plate-shaped piece 2, and the width of the cut groove 6 of the second plate-shaped piece 2 is the first plate shape. Since the thickness is equal to or greater than the thickness of the piece 1, the cut groove 6 of the second plate-shaped piece 2 is reliably inserted into the cut groove 3 of the first plate-shaped piece 1.

  Subsequently, as shown in FIG. 3 (c), the cut groove 3 of the first plate-like piece 1 and the cut groove 6 of the second plate-like piece 2 are engaged. Specifically, the pair of protrusions 4 a, 4 b of the first plate-shaped piece 1 are locked to the locked portions 8 of the second plate-shaped piece 2 and the pair of protrusions of the second plate-shaped piece 2. The parts 7 a and 7 b are locked to the second locked part 5 of the first plate-like piece 1. Thereby, as shown in FIG. 4, the 1st plate-shaped piece 1 and the 2nd plate-shaped piece 2 are combined. In addition, the 1st plate-shaped piece 1 and the 2nd plate-shaped piece 2 are the 1st plate-shaped piece 1 in the process of engaging the notch groove 3 of the 1st plate-shaped piece 1, and the notch groove 6 of a 2nd plate-shaped piece. The pair of protrusions 4 a and 4 b come into contact with the bottom of the cut groove 6 of the second plate-shaped piece 2, and at the same time, the pair of protrusions 7 a and 7 b of the second plate-shaped piece 2 It contacts the bottom 9 of the cut groove 3. However, since the first plate-like piece 1 and the second plate-like piece 2 have a certain flexibility as described above, the first plate-like piece 1 and the second plate-like piece 2 are engaged with each other. Thus, the cut groove 3 of the first plate piece 1 expands following the thickness of the second plate piece 2, and the cut groove 6 of the second plate piece 2 follows the thickness of the first plate piece 1. And spread. As a result, the pair of ridges 4 a and 4 b of the first plate-like piece 1 are locked to the locked portions 8 of the second plate-like piece 2 and the pair of ridges 7 a of the second plate-like piece 2. , 7b are locked to the second locked portion 5 of the first plate-like piece 1.

  In addition, in the above-mentioned, although the procedure in the case of combining the 1st plate-shaped piece 1 and the 2nd plate-shaped piece 2 was demonstrated, when unraveling the combination of the 1st plate-shaped piece 1 and the 2nd plate-shaped piece 2 The first plate-like piece 1 and the second plate-like piece 2 may be slid in the direction opposite to the engaging direction.

<Advantages>
In the three-dimensional model piece set, the first plate-like piece 1 and the second plate-like piece 2 have cut grooves 3 and 6 on the side edges, respectively. The first plate-like piece 1 and the second plate-like piece 2 Since the cut grooves 3 and 6 are engaged and combined in an intersecting state, the first plate-like piece 1 and the second plate-like piece 2 are accurately engaged in a fixed posture, and the three-dimensional effect is easily emphasized. Further, in the three-dimensional model piece set, a locking portion 4 that is locked to each other when the first plate-shaped piece 1 and the second plate-shaped piece 2 are combined is formed in the cut groove 3 of the first plate-shaped piece 1. Since the to-be-latched part 8 is formed on the extension line of the cut groove 6 of the second plate-like piece 2, combining the first plate-like piece 1 and the second plate-like piece 2 enables these latching parts 4 and The locked portion 8 is locked at the same time. Therefore, the three-dimensional model piece set can easily and reliably connect a pair of plate-like pieces.

  In the three-dimensional model piece set, the second locked portion 5 is formed on the extended line of the cut groove 3 in the first plate-like piece 1 where the lock portion 4 is formed, and the cut groove of the second plate-like piece 2 is formed. 6 is formed with a second locking portion 7 that is locked to the second locked portion 5 when combined, so that the locking portion 4 of the first plate-like piece 1 and the hooked portion of the second plate-like piece 2 are formed. The locking part 8, the second locked part 5 of the first plate-like piece 1 and the second locking part 7 of the second plate-like piece 2 can be locked together, and a pair of plate-like pieces can be Furthermore, it can connect reliably.

  The three-dimensional model piece set is a pair of protrusions 4a and 4b in which the locking portion 4 extends in the groove forming direction of the pair of side portions 10 of the cut groove 3 of the first plate-shaped piece 1, and the locked portion Since 8 is a locking hole penetrating in the thickness direction of the second plate-like piece 2, the pair of plate-like pieces can be connected more easily and reliably. That is, the three-dimensional model piece set can be locked so that the second plate-shaped piece 2 is sandwiched from both sides by the pair of protrusions 4a, 4b of the first plate-shaped piece 1. In addition to not taking time and effort, it is possible to more accurately prevent disconnection after locking. Moreover, according to this structure, since the connection of the locking part and the locked part can be released relatively easily, the workability of removing the pair of plate-like pieces after combination is excellent. Furthermore, since the three-dimensional model piece set can engage the pair of plate-like pieces by engaging the locking portion 4 and the locked portion 8 with each other, the conventional plate-like piece set can be engaged. Thus, a pair of plate-like pieces can be firmly connected without using an adhesive or the like.

  In the three-dimensional model piece set, the depth direction of the cut groove 3 and the extending direction of the side edge on which the cut groove 3 is formed are orthogonal to each other. In addition, the pair of plate-like pieces can be more firmly connected.

  Since the plate-like piece (first plate-like piece 1) has a cut groove 3 that engages with a cut groove of another plate-like piece, the cut groove 3 engages with a cut groove of another plate-like piece. By combining them in an intersecting state, it is possible to accurately engage with other plate-like pieces in a fixed posture, and it is easy to emphasize the stereoscopic effect. Furthermore, the said plate-shaped piece (1st plate-shaped piece 1) has the latching | locking part 4 formed in the notch groove 3, and the to-be-latched part (2nd to-be-latched part) formed on the extension line | wire of the notch groove 3. FIG. 5), by combining with other plate-like pieces, this locking portion 4 is locked to the locked portion of the other plate-like piece, and the locked portion (second locked portion) 5) can be locked to the locking portions of other plate-like pieces. Therefore, the said plate-shaped piece (1st plate-shaped piece 1) can be connected with another plate-shaped piece easily and reliably.

[Second Embodiment]
<Plate-shaped piece set>
The plate-like piece set 21 (three-dimensional model piece set) in FIG. 5 includes a plurality of plate-like pieces that are combined in an intersecting state to assemble a three-dimensional model. Specifically, the plate-like piece set 21 in FIG. 5 includes a first plate-like piece 22 and a second plate-like piece 23 as the plurality of plate-like pieces.

(Plate-shaped piece)
As shown in FIG. 5A, the first plate-like piece 22 is formed in a plate shape having a substantially uniform thickness. The first plate-like piece 22 has a pair of cut grooves 24 on the same side edge. In the pair of cut grooves 24 of the first plate-like piece 22, a pair of locking portions 25 that are locked at the time of combination are formed. The side edges where the pair of cut grooves 24 of the first plate-like piece 22 are formed are linear.

  The second plate-like piece 23 has a pair of cut grooves 26 on the same side edge. The pair of cut grooves 26 of the second plate-like piece 23 are formed with a pair of locking portions 27 that are locked when combined. The shape and forming material of the second plate-like piece 23 are the same as those of the first plate-like piece 22. That is, the pair of cut grooves 26 of the second plate-shaped piece 23 are the same as the pair of cut grooves 24 of the first plate-shaped piece 22, and the pair of locking portions 27 of the second plate-shaped piece 23 are the first plate-shaped. It is the same as the pair of locking portions 25 of the piece 22. Therefore, only the first plate-like piece 22 will be described below, and the description of the second plate-like piece 23 will be omitted. However, in the present embodiment, the first plate-like piece 22 and the second plate-like piece 23 have the same shape and size, but the first plate-like piece 22 and the second plate-like piece 23 are three-dimensional models to be assembled. Different shapes (contours) or sizes may be formed according to the shape, size, or the like.

(First plate-shaped piece)
The forming material, the manufacturing method, the length in the longitudinal direction, the length in the short direction, and the thickness of the first plate-like piece 22 can be the same as those of the first plate-like piece 1 in FIG.

  The notch groove 24 engages with the notch groove 26 of the second plate-like piece 23 when combined. That is, the cut groove 24 is engaged with the cut groove 26 of the second plate-like piece 23 when combined. The cut groove 24 has a bottom portion 28 and a pair of side portions 29 disposed in parallel to each other. The depth direction of the cut groove 24 is orthogonal to the extending direction of the side edge where the cut groove 24 is formed. The pair of side portions of the cut groove 24 is disposed in parallel with the thickness direction of the first plate-like piece 22. Furthermore, the side edge side end portions of the pair of side portions 29 are chamfered so that the combination work with the second plate-shaped piece 23 is easy.

  The ratio of the depth and width of the cut groove 24, the ratio of the depth of the cut groove 24 to the length in the short direction of the first plate-like piece 22, and the ratio of the depth of the cut groove 24 to the width of the cut groove 24 are shown in FIG. The first plate-like piece 1 can be the same.

  The lower limit of the ratio of the depth of the cut groove 24 to the length in the short direction of the first plate-like piece 22 is preferably 1/3 and more preferably 1/2. On the other hand, the upper limit of the ratio of the depth of the cut groove 24 to the length in the short direction of the first plate-like piece 22 is preferably 3/4, and more preferably 2/3. When the ratio of the depth of the cut groove 24 to the length in the short-side direction of the first plate-like piece 22 is less than the lower limit, there is a possibility that the connection strength in the state combined with the second plate-like piece 23 cannot be obtained sufficiently. . Conversely, when the ratio of the depth of the cut groove 24 to the length in the short direction of the first plate-like piece 22 exceeds the above upper limit, the strength of the portion on the extension line of the cut groove 24 of the first plate-like piece 22 decreases. In addition, the first plate-like piece 22 may be easily damaged.

  The locking part 25 is locked at the time of combination. Specifically, the locking portion 25 is locked between the bottom portion of the cut groove 26 of the second plate-like piece 23 and the locking portion 27 when combined. The locking portion 25 is formed on the pair of side portions 29 of the cut groove 24. The locking portion 25 is formed as a pair of protrusions projecting inwardly from the pair of side portions 29 of the cut groove 24, and specifically, a pair of protrusions extending in the groove forming direction of the pair of side portions 29 of the cut groove 24. It is formed as strips 25a, 25b.

  The pair of ridge portions 25 a and 25 b are disposed at positions facing the pair of side portions 29. The pair of protrusions 25a and 25b are formed in an arc shape in cross section in the plane direction. The pair of ridge portions 25 a and 25 b are formed across both ends of the pair of side portions 29 in the groove forming direction. The distance between the top portions of the pair of ridge portions 25 a and 25 b is set to be equal to or less than the thickness of the second plate-like piece 23.

  The lower limit of the ratio of the protruding height of the pair of protruding portions 25a and 25b to the width of the cut groove 24 is preferably 1/20, and more preferably 1/15. On the other hand, the upper limit of the ratio of the protrusion height of the pair of protrusions 25a and 25b to the width of the cut groove 24 is preferably 1/7, and more preferably 1/10. When the ratio of the protrusion height of the pair of protrusions 25a, 25b to the width of the cut groove 24 is less than the lower limit, the pair of protrusions 25a, 25b are the bottoms of the cut grooves 26 of the second plate-like piece 23 when combined. In addition, there is a risk of slipping out from between the locking portions 27 formed in the cut groove 26. Conversely, when the ratio of the protrusion height of the pair of protrusions 25a, 25b to the width of the cut groove 24 exceeds the above upper limit, the pair of protrusions 25a, 25b is replaced with the bottom of the cut groove 26 of the second plate-shaped piece. In addition, it may be difficult to insert between the locking portions 27 formed in the cut groove 26.

The pair of protrusions 25 a and 25 b is provided on the bottom 28 side of the cut groove 24. The lower limit of the ratio (L ₃ / D) of the distance L ₃ between the bottom 28 of the cut groove 24 and the pair of protrusions 25a, 25b with respect to the depth D of the cut groove 24 is preferably 1/10, and 1/4 Is more preferable. On the other hand, the upper limit of the ratio (L ₃ / D) is preferably 2/5, and more preferably 1/3. When the ratio (L ₃ / D) is less than the lower limit, when the cut groove 24 of the first plate piece 22 is engaged with the cut groove 26 of the second plate piece 23, There is a possibility that the distance between the pair of protrusions 25a and 25b is not sufficiently wide, and it becomes difficult to engage the first plate-like piece 22 and the second plate-like piece 23. On the other hand, when the ratio (L ₃ / D) exceeds the upper limit, the play in the state of being combined with the second plate-like piece 23 is increased, and the first plate-like piece 22 and the second plate-like piece 23 are accurately obtained. There is a possibility that it can not be connected to.

<Combination procedure>

As a result, as shown in FIG. 7, the first plate-like piece 22 and the second plate-like piece 23 are combined. As described above, the width of the cut groove 24 of the first plate-shaped piece 22 is equal to or greater than the thickness of the second plate-shaped piece 23, and the width of the cut groove 26 of the second plate-shaped piece 23 is the first plate-shaped. Since the thickness is equal to or greater than the thickness of the piece 22, the cut groove 26 of the second plate-shaped piece 23 is reliably inserted into the cut groove 24 of the first plate-shaped piece 22.

  In addition, in the above-mentioned, although the procedure in the case of combining the 1st plate-shaped piece 22 and the 2nd plate-shaped piece 23 was demonstrated, when unraveling the combination of the 1st plate-shaped piece 22 and the 2nd plate-shaped piece 23 The first plate-like piece 22 and the second plate-like piece 23 may be slid in the direction opposite to the engagement direction.
