Description

Stacked three-dimensional model

[0001] The present invention relates to a laminated three-dimensional model, and more specifically, to a laminated three-dimensional model in which a desired three-dimensional model is formed by laminating layers of plate-shaped three-dimensional models of various shapes, and a pattern representing a part of the three-dimensional model is printed on a plate-shaped plate such as paper, wood, or plastic, and the plate is cut according to the shape of the three-dimensional model to create layers, and these layers are laminated according to a preset order to form three-dimensional models having various shapes, forms, and colors.

[0002] In general, there are a variety of three-dimensional toy products that are widely available, such as plastic models and Legos, and products that create three-dimensional shapes using paper, such as papercraft, are known as a type of craft.

[0003] Papercraft, also known as paper toys, is an activity that involves cutting sheets of paper into plates with specific shapes and bend lines and then using simple tools such as glue to attach them to the desired shape, thereby completing a three-dimensional shape. It is a hobby enjoyed by people of all ages, from infants to adults.

[0004] Paper toys are known to be particularly helpful in developing children's brains and improving concentration because they use commonly used materials such as paper and glue, and do not require a lot of money. They are also made by folding and pasting paper using hands.

[0005] However, Lego and plastic models have limitations in the accessibility of young children and non-experts because they require parts with specific shapes and forms to be attached or assembled according to blueprints in order to create a three-dimensional model, and paper toys can be made by people of all ages, from young children to adults, by folding or cutting paper into specific shapes and then pasting them together, but there are limitations in that the quality of the completed three-dimensional shape is poor or the durability is low.

[0006] In particular, paper toys print various patterns on a single base plate and use die cutting processing to make cutting easy, but since the pattern is printed on only one side, there is a problem that the part where the pattern is not printed is exposed after the three-dimensional shape is created. In addition, the use of adhesive is essential to create the desired three-dimensional shape, and each part must be attached in the exact location to assemble the desired three-dimensional shape, so there is a problem that assembly is difficult. Moreover, because paper toys create three-dimensional shapes by cutting and attaching part of the base plate, there is a limit to creating various types of three-dimensional shapes, and there is a problem that it is difficult to create dynamic three-dimensional shapes or three-dimensional shapes with high external perfection.

[0007] A conventional paper toy is disclosed in Korean Patent No. 1905707. Patent '707 relates to a paper toy that can be made into three-dimensional toys such as animals, insects, and robots by folding paper, and which includes a base paper made of paper material, an assembly paper formed thicker than the base paper, a cutting line formed along the edge of the assembly paper so as to separate the assembly paper from the base paper, and a surface reinforcement layer containing polyethylene resin. The paper toy of Patent '707 has the advantage of being able to neatly separate the assembly part from the conventional base paper and making it easy to assemble the paper model toy, but has the problem that the finish of the completed paper toy is rough because the pattern is formed on only one side, the manufacturing process is complicated because the surface reinforcement layer is formed on the surface of the base paper, and there are limitations in implementing various three-dimensional shapes.

[0008] The present invention provides a laminated three-dimensional model that can obtain the same effect as printing a pattern on both sides by printing a pattern that implements a three-dimensional shape on one side using various materials such as paper, wood, and plastic as a base, can efficiently implement a three-dimensional model of any shape by overcoming the limitations of the lamination method by utilizing layer members of various shapes, can laminate layer members by a fitting method so that even an unskilled person can produce a three-dimensional model with high completion, and can easily perform three-dimensional shape assembly by minimizing the use of adhesive in laminating layer members.

[0009] In order to achieve the above object, the laminated three-dimensional model of the present invention is a three-dimensional model made by laminating a plurality of layer members to form a three-dimensional shape, the three-dimensional model comprising: a foldable layer member that forms a part of the three-dimensional shape, has a pattern representing a part of the three-dimensional shape formed on one side thereof, and is folded so that the pattern formed on one side thereof is displayed on both sides; a protruding layer member that forms a part of the three-dimensional shape, has a pattern representing a part of the three-dimensional shape on one side thereof, and has a protrusion formed thereon for laminating the layer member in a fitting manner; and a recessed layer member that is combined with the protruding layer member, has a pattern representing a part of the three-dimensional shape on one side thereof, and has a protrusion of the protruding layer member and a custom-shaped fitting portion formed thereon.

[0010] In addition, the laminated three-dimensional model is characterized in that it is formed by laminating a foldable layer member, a protruding layer member, and a sunken layer member on both sides based on a reference layer member placed at a preset reference position of the laminated three-dimensional model.

[0011] In addition, it is characterized in that an alignment member is inserted into each layer member to accurately stack the foldable layer member or the sunken layer member, and an alignment hole is formed into which the alignment member is inserted at a preset position of the foldable layer member and the insertable layer member.

[0012] In addition, the protruding layer member and the sunken layer member are characterized in that they are a double-sided two-layer structure with a pattern printed on them, the protruding layer member has a protrusion formed on one side of the double-sided surface, and the sunken layer member has a fitting part formed on one side of the double-sided surface to be fitted with the protrusion.

[0013] In addition, the above-mentioned laminated three-dimensional model further includes a three-layer structure multi-purpose layer member that is joined at both ends and has a protrusion formed on one surface.

[0014] In addition, the above-described laminated three-dimensional model further includes an attachment member that is joined to a preset position of the three-dimensional model formed by laminating each layer member.

[0015] In addition, the foldable layer member or the protruding layer member is characterized in that the pattern includes an alignment line indicating the shape of the layer member to be laminated on one side so that it can be laminated at an accurate position.

[0016] The present invention, having a configuration as described above, can be based on various materials such as paper, wood, and plastic, and can obtain the effect of double-sided printing through single-sided printing of a pattern required to implement a three-dimensional shape.

[0017] In addition, by utilizing various types of layered materials, it is possible to efficiently implement three-dimensional models of all shapes, overcoming the limitations of the stacking method.

[0018] In addition, by stacking layers in a fitting manner, a high-quality three-dimensional model can be produced without errors, and the use of adhesive can be minimized when stacking layer members, making it easy to assemble three-dimensional shapes.

[0029] Hereinafter, a layered three-dimensional model according to the present invention will be described in detail with reference to the drawings.

[0031] In the case of conventional paper toys, a pattern for a three-dimensional shape is printed on one side of a base made of paper, so that after assembling the three-dimensional shape, a blank area without a pattern is inevitably created as shown in Fig. 9, resulting in a poor finish of the three-dimensional shape. In addition, when producing a three-dimensional shape by lamination, the bond between layers relies on adhesive, so there is a limit to the three-dimensional shape that can be implemented. In addition, when assembling a three-dimensional shape, each layer must be assembled in the exact position, making it difficult to assemble a three-dimensional shape with a high degree of completion.

[0032] The present invention relates to a three-dimensional model that produces a target three-dimensional shape by stacking two or more plate-shaped layer members to solve the problems of the conventional paper toy as described above, comprising: a foldable layer member (100) that is stacked to form a part of a three-dimensional shape and is composed of a first foldable layer (100a) and a second foldable layer (100b) and has a pattern (D) formed on one surface of each layer (100a, 100b) to represent a three-dimensional shape; a protruding layer member (200) that includes a first protruding layer (200a) and a second protruding layer (200b) that form a part of a three-dimensional shape and have a pattern (D) formed on one surface of each layer (100a, 100b) similar to the foldable laser member (100), and has a protrusion (210) formed on one of the first protruding layer (200a) or the second protruding layer (200b) to be stacked in a fitting manner with another layer member; and a foldable layer Similar to the member (100) and the protruding layer member (200), the member comprises a first recessed layer (300a) and a second recessed layer (300b) having a pattern (D) formed on one surface thereof, and a recessed layer member (300) having a fitting portion (310) formed in one of the first and second recessed layers (300a, 300b) to be fitted with a protrusion (210). In addition, the laminated three-dimensional model of the present invention may further include a multipurpose layer member (400) formed by folding two or three layers, similar to each layer member (100, 200, 300), and having a pattern (D) formed on one surface thereof, but having both a protrusion (210) and a recessed portion (310).

[0033] The laminated three-dimensional model (10) of the present invention is manufactured by laminating two or more layer members (100, 200, 300, 400) as illustrated in FIGS. 1, 6, 7, 8, etc. to create a desired three-dimensional shape. The material of each layer member (100, 200, 300, 400) can be manufactured from paper, as with general paper toys, but it can also be made from any material that can be cut into a certain shape, such as wood or plastic, and is in the form of a plate. The laminated three-dimensional model (10) of the present invention is formed by laminating two or more layer members as shown in FIGS. 6 and 7, and each layer member has a preset shape according to the position of the three-dimensional model. Such layer members can be manufactured in a shape suitable for each position without a separate cutting process during the manufacturing stage. However, in terms of the manufacturing process and manufacturing cost, it is preferable to form a cutting line along the outer line of each layer member in a base sheet (not shown) having a size larger than each layer member, and then separate the layer member from the base sheet by an external force or a cutting tool such as a cutter knife, and then manufacture the laminated three-dimensional model (10) of the present invention.

[0034] In addition, the laminated three-dimensional model (10) of the present invention is manufactured by laminating each layer member (100, 200, 300, 400) in both directions as needed around a reference layer member (700) provided at a specific location according to the three-dimensional model, as illustrated in FIG. 7. The reference layer member (700) may be selected from among a foldable layer member (100), a protruding layer member (200), a recessed layer member (300), or a multipurpose layer member (400) depending on the shape of the three-dimensional model to be manufactured.

[0035] In addition, since the laminated three-dimensional model (10) of the present invention is laminated to exhibit a desired three-dimensional shape, as in the example of the three-dimensional model illustrated in FIG. 1, it is not laminated haphazardly, but each layer member must be combined at an accurate position. To this end, the laminated three-dimensional model (10) of the present invention can induce each layer member to be accurately laminated by installing an alignment member (500) on a specific layer member so that each layer member can be combined at an accurate position, and then forming an alignment hole (600) in the layer member to be combined thereafter. Of course, the laminated three-dimensional model (10) of the present invention can be accurately combined even without the alignment member (500) because the protruding layer member (200) and the recessed layer member (300) are fitted and combined through the protrusion (210) and the fitting portion (310), and thus the alignment member (500) is not necessary for all layer members. That is, the protrusion (210) provided in the protruding layer member (200) and the multipurpose layer member (400) can perform the role of the alignment member (500).

[0036] The foldable layer member (100) of the present invention is composed of two layer members (100a, 100b) as described above. Conventional paper toys, as illustrated in FIG. 9, have a pattern for displaying a three-dimensional shape printed only on one side, resulting in a portion (C) where the pattern for expressing the three-dimensional shape is missing, and this blank portion (C) reduces the completeness of the three-dimensional shape produced. To solve this problem, it is necessary to print different patterns on both sides. However, printing patterns on both sides not only excessively increases the manufacturing cost of the three-dimensional model, but also causes a problem of matching the patterns printed on both sides, resulting in a problem of reduced mass productivity. The foldable layer member (100) of the present invention is formed by combining two layer members (100a, 100b), so that one side of the two sides is designated as a pattern-forming surface (110) and the other side, on which no pattern is formed, is joined against each other, thereby solving the problem of printing patterns on both sides. FIG. 2 illustrates an example of a foldable layer member (100). As shown in the right cross-sectional view, a partially processed fold line (50) for folding is formed on the pattern forming surface (110) so that the two layers can be folded around the fold line (50). Even if a pattern expressing a three-dimensional shape is printed only on the pattern forming surface (110), the effect of a pattern being printed on both sides can be obtained. The foldable layer member (100) can be manufactured as shown in FIG. 2, but it can also be manufactured separately and then the two layers (100a, 100b) can be combined. It is preferable to combine the two layers (100a, 100b) using an adhesive. A general adhesive can be used as the adhesive, and when combining like a sticker, the release paper on the top of the adhesive can be removed and then combined, or a method of activating the adhesive just before combining using water can be used. This combining method can be equally utilized not only for combining the two layers (100a, 100b) but also for combining each layer member.

[0037] The protruding layer member (200) of the present invention is configured such that a protrusion (210) is formed on either the first protruding layer (200a) or the second protruding layer (200b) in order to be coupled with the recessed layer member (300) in a fitting manner. The protrusion (210) provided on the protruding layer member (200) is manufactured to have the same shape as the fitting portion (310) formed on the recessed layer member (300). It is preferable in terms of manufacturing cost to form the protrusion (210) by passing through another layer after forming a folding line (50) as illustrated in FIG. 3. Of course, when the fitting portion (310) is complex as illustrated in FIG. 1, a separate layer may be provided and attached to one surface of the first and second protruding layers (200a, 200b) to form three layers. In this case, there is a disadvantage that the production of a three-dimensional model becomes complicated, but there is an advantage that a three-dimensional shape that cannot be realized with a conventional paper toy can be produced. In addition, the protrusion (210) can be produced in a manner in which three layers are folded through the folding line (50) as described above, but although there is an advantage in that one base sheet is used, there is a disadvantage in that the manufacturing process becomes complicated because the folding line (50) must be formed on both sides.

[0038] The sunken layer member (300) of the present invention is configured such that a fitting portion (310) is formed in one of the first and second sunken layers (300a, 300b) in order to be fitted and coupled with the protruding layer member (200) described above. The fitting portion (310) is provided in the same shape as the protruding portion (210), but it is preferable to form the fitting portion (310) slightly smaller than the protruding portion (210) in order to increase the bonding force. Since the functions of the alignment member (500) and the alignment hole (600) described above can be performed through the protruding layer member (200) and the sunken layer member (300), the use of the alignment member (500) and the alignment hole (600) can be minimized, and the use of adhesive can also be minimized.

[0039] The multipurpose layer member (400) of the present invention has a configuration that includes both the protrusion (210) and the fitting (310) described above. The multipurpose layer member (400) has the advantage of minimizing the number of layers stacked and allowing for the expression of a wider variety of three-dimensional shapes.

[0040] The pattern formed on each layer member of the present invention may include alignment lines (not shown) within the pattern so that each layer member can be precisely combined. These alignment lines are displayed in line with the outline of the layer member to be combined next, and are essential for conventional payload toys. However, since the layer members of the present invention can be precisely combined through the protrusions (210) and the fittings (310), the alignment lines are not necessarily required, and thus the alignment lines can be utilized as needed. This feature of minimizing the alignment lines not only minimizes the use of adhesive, but also has the advantage of allowing accurate assembly of the three-dimensional model (10) even by an unskilled person.

[0041] FIG. 8 illustrates an example of a laminated three-dimensional model of the present invention. In order to produce a more complete laminated three-dimensional model (10) of the present invention, attachments (800) can be attached to preset locations. For example, although shown as a pattern in FIG. 8, the dinosaur's eyes can be produced as separate attachments (800) and attached to preset locations during the assembly process or after assembly is complete.
