Description

[Technical Field]

[0001] The present invention relates to a model element, a model part, and a method for manufacturing a model element. [Background technology]

[0002] Model toys use multiple types of parts, each made from a different synthetic resin. This allows for the creation of a model toy that combines multiple parts of different colors, for example. These parts are formed as a model element by connecting multiple parts to a runner, and each part is removed from the runner when assembling.

[0003] The above-mentioned model element is manufactured by pouring synthetic resin into a mold and molding it. Such model elements include those molded using a single synthetic resin and those molded using multiple different synthetic resins. When molding a single model element using multiple different synthetic resins, it is possible to form a single model element including parts of different colors. Patent Document 1 proposes a model element having multiple runners that group together synthetic resin model components of the same synthetic resin. Patent Document 2 proposes a multi-color molding device that removes a molded product molded in one mold and transfers it to the next mold, where it is wrapped around and insert-molded to form a single completed multi-color molded product.

[0005] The above-mentioned conventional technology allows for the formation of multicolored model elements, and furthermore, by using insert molding or rotational molding, it is possible to form a single part in multiple colors. Also, some model toys have detachable decorative parts, such as weapons and armor. To attach these decorative parts to the model toy body, a mechanism such as connecting parts that are compatible with the model toy body and the attached decorative parts is required. Furthermore, because such connecting parts have holes for connecting multiple components, it has been difficult to provide them connected to a runner as a single part.

[0013] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention as claimed, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be arbitrarily combined. Furthermore, the same reference numerals are used for the same or similar components, and redundant explanations will be omitted.

[0014] <Appearance of the model toy> An example of the external configuration of the model toy 100 according to this embodiment will be described with reference to Fig. 1A. Fig. 1A(a) shows the external front view of the model toy 100, and Fig. 1A(b) shows the external rear view of the model toy 100. Note that the x, y, and z arrows indicate the upward, left, and forward directions of the model toy, respectively, and this also applies to the other drawings.

[0015] The model toy 100 includes a head 101, an upper body 102, arms 103a and 103b, a waist 104, legs 105a and 105b, and a connecting part 106, which constitute a main body. In this embodiment, a humanoid robot is used as an example of a model toy, but this is not intended to limit the present invention, and the present invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and ornaments.

[0016] The head 101 is rotatably connected to an upper body 102. A right arm 103b and a left arm 103a are further connected to the sides of the upper body 102 by connecting members, and a waist 104 is connected to the lower part of the upper body 102. The waist 104 includes hip joints, and a right leg 105b and a left leg 105a are each rotatably connected to the waist 104.

[0017] The model toy 100 according to this embodiment also includes a connecting portion 106 on its back surface. The connecting portion 106 according to this embodiment has two holes. A connecting part 200 is connected to the connecting portion 106, to which decorative parts such as armor and other weapons are attached. The connecting part has multiple surfaces, with at least one hole formed on each surface. In other words, the connecting part 200 is a part for expanding the limited holes formed in the model toy 100, and is capable of connecting a variety of decorative parts compared to the connecting portion 106 formed directly on the model toy 100. Note that, although this embodiment describes an example in which the connecting portion 106 is formed on the back surface of the model toy 100, this is not intended to limit the present invention, and the connecting portion 106 may be formed anywhere on the model toy 100.

[0018] <Model base (runner) configuration> An example of the configuration of a model element according to this embodiment will be described with reference to FIG. 1B. The x, y, and z arrows respectively indicate the upward, leftward, and forward directions of a model element having multiple parts connected to a runner. Here, a runner refers to a rod-shaped plastic portion in a toy model such as a plastic model to which multiple parts are connected before assembly and arranged in a surrounding manner. The runner may also refer to the entirety, including the multiple connected parts. Here, the term "model element" is used to refer to the entire runner including the multiple parts.

[0019] The model element 110 shown in FIG. 1B is a multi-color molded model element. Here, a model element molded in four colors using synthetic resin will be described as an example. However, this is not intended to limit the scope of the present invention, and multi-color molding may be performed using synthetic resin materials of other numbers of different colors. The model element 110 has a runner 111, a gate 112, and a part 113, and further includes a connecting part 200, which is a model component molded in multiple colors.

[0020] A model element 110 including a multi-color molded model component is formed by combining parts molded from a plurality of different colored synthetic resins. The model element 110 is manufactured by first molding a first colored synthetic resin (first synthetic resin) into a mold from an injection device (not shown), then after the poured resin has solidified, second molding by injecting a second colored synthetic resin (second synthetic resin) from the injection device, and then molding by injecting other colored synthetic resins, repeating this process. The detailed manufacturing process of the model component will be described later.

[0021] In this embodiment, an example in which synthetic resins of different colors are used will be described, but this is not intended to limit the scope of the present invention. For example, synthetic resins of different softness may be used, or parts of different hardness may be molded into a single part.

[0022] Furthermore, to form a single part in multiple colors, runners for the flow of different synthetic resins must be formed to match the shape of each part. However, the area for forming a single part is small, making it difficult to form multiple flow paths. Therefore, in the present invention, a submarine gate (not shown) may be used to secure flow paths in some gates. Here, a submarine gate (tunnel gate) is a tunnel-shaped gate formed in a mold that is simultaneously separated from the runner when the molded product is removed from the mold. Note that this is not intended to limit the present invention, and it is not necessary to use a submarine gate; other gates, such as a side gate or a jump gate, may also be used.

[0023] Furthermore, according to this embodiment, the model element 110 is molded using four colors of synthetic resin, and runners of different colors are connected to each other at multiple locations. In this embodiment, the connection between runners of different colors (different resin materials) is achieved by, for example, injecting a first color synthetic resin (first synthetic resin) from an injection device (not shown) to perform primary molding, and after the poured resin has solidified to a certain extent, releasing a stopper member that blocks the flow of the first color synthetic resin (first synthetic resin) on the runner into the second color synthetic resin (second synthetic resin), and then injecting the second color synthetic resin (second synthetic resin) from the injection device to perform secondary molding, and repeating these steps (tertiary molding and quaternary molding).

[0024] <Configuration of connecting parts> The configuration of the connecting parts 200, which are model components of the model toy 100 according to this embodiment, will be described with reference to Fig. 2. Fig. 2 shows a perspective view of the connecting parts 200.

[0025] The connected part 200, which is a model component, is provided in a state connected to the model base body 110 as one part of the model toy 100. The connected part 200 detached from the runner 111 is formed in a block shape including multiple holes 201a-201c. Holes may also be formed on surfaces not shown. It is not intended that the connected part of the present invention be limited to a block shape, and it may be formed in other shapes such as a sphere or a triangular prism. Furthermore, although this embodiment describes a form in which one hole is formed on one surface, this does not limit the present invention, and multiple holes may be formed on each surface. Furthermore, the number of holes formed on each surface may vary. Modified examples of the connected part will be described later using FIG. 5.

[0026] The connecting part 200 is composed of multiple synthetic resins 202, 203. For example, the connecting part 200 according to this embodiment is composed of a synthetic resin 202 of a predetermined color and a synthetic resin 203 of a different color. The synthetic resin 202 of the predetermined color forms the body of the connecting part, and the synthetic resin 203 of the different color forms the hole of the connecting part and the plate portion positioned to be sandwiched in the body. This allows for the provision of a multi-color molded connecting part with excellent design. Note that, although the present embodiment describes an example in which synthetic resins of different colors are used to form the connecting part, this is not intended to limit the present invention, and the connecting part may be formed using synthetic resins of different strengths. For example, by using a synthetic resin with a higher strength for forming the hole, damage to the connecting part due to the attachment and detachment of the connecting terminal, as described below, can be reduced.

[0027] As shown in Figure 2(a), a connecting terminal 210 is connected to the hole 201 of the connecting part 200. The connecting terminal 210 is composed of connecting portions 211, 213 and a disk portion 212. The connecting portions 211, 213 are formed in a cylindrical shape at both ends, with one end inserted into the hole 201 of the connecting part 200 and the other end inserted into a hole formed in the main body or decorative portion of the model toy. The disk portion 212 has a radius longer than the radii of the connecting portions 211, 213 and is formed between the connecting portions 211 and 213.

[0028] The hole 201 is formed by a recess that receives the disk portion 212 and a cylindrical hole at the back of the recess that receives the connecting portions 211 and 213. Therefore, as shown in FIG. 2(b), the connecting terminal 210 connected to the connecting part 200 is fitted so that the disk portion 212 is fitted into the recess formed in the hole 201c and the connecting portion 211 is inserted into a hole formed at the back of the recess. In the state shown in FIG. 2(b), a connecting portion 313 is exposed at the other end of the connecting terminal 210. This connecting portion 313 can be connected to a hole formed in the main body or decorative portion of the model toy 100, thereby connecting the model toy 100 and the decorative portion.

[0029] <Model part runner configuration> The runner configuration of the model component according to this embodiment will be described with reference to Fig. 3. Fig. 3 shows a perspective view of a portion where a connecting part 200, which is part of the model base body 110 shown in Fig. 1B, is connected to a runner.

[0030] Reference numeral 300 denotes a portion of the model base body 110. The portion 300 is composed of runners 301-304 formed from a plurality of different synthetic resins, and connecting parts 200 connected to each runner. The connecting parts 200 can be removed from the runners by removing the runners inserted into the holes and detaching them from gates 305 shown by dotted lines.

[0031] The runners 301-304 are formed using synthetic resins of different colors or properties. In this embodiment, the different synthetic resins include a crystalline resin (POM: polyacetal) and an amorphous resin (PS: polystyrene). POM has high self-lubricity and does not stick to other resins. Furthermore, it has a low shrinkage rate when cooled from a molten state and solidified, resulting in high dimensional stability. In this embodiment, the runners 301 and 302 are made of a crystalline resin (POM), and the runners 303 and 304 are made of an amorphous resin (PS). Because the runners 301 and 302 are resins that form the portions inserted into the hole 201 of the connecting part 200, it is desirable to use POM, which is strong and highly dimensionally stable. Note that if the runners 301 and 302 that form these portions were made of an amorphous resin (PS), the portions inserted into the hole would be crushed, causing the hole to deform, e.g., into an ellipse, making it difficult to remove the runners 301 and 302 from the connecting parts.

[0032] Each of the runners 301 to 304 is formed sequentially in different molding processes, and the parts formed in each process are combined to form the connected part 200. Note that the connected part 200 is configured to include the synthetic resin used in the runners 303 and 304, and the synthetic resin (PS) used in the runners 301 and 302 is formed only as a portion to be filled in the hole of the connected part 200. Note that this configuration is one example and is not intended to limit the present invention.

[0033] <Model part manufacturing process> With reference to FIG. 4, the manufacturing process for the portion 300 of the model element 110 according to this embodiment will be described. FIGS. 4(a) to 4(d) show perspective views of the runners formed in each molding process. For ease of explanation, the molding process for the portion 300 will be described, rather than the molding process for the entire model element 110. Here, an example will be described in which synthetic resins of different colors are used to mold the runners 301 to 304, but this is not intended to limit the scope of the present invention. For example, as explained with reference to FIG. 3, the runners 301 to 304 may be molded using synthetic resins of different properties (crystalline resin and amorphous resin). Alternatively, the runners may be molded using synthetic resins of different colors and different properties.

[0034] FIG. 4(a) shows a runner 301 formed in a first molding step using a synthetic resin of a first color. The runner 301 has portions 311a and 311b that are embedded in the left and right holes of the connecting part 200. For example, portion 311a is molded by the first synthetic resin flowing into the mold from the left in the figure, and portion 311b is molded by the first synthetic resin flowing into the mold from a different direction (here, the right in the figure) than portion 311a. Furthermore, portions 311a and 311b, which are molded by flowing in from two directions, are not connected at their centers (the center of the connecting part 200). Furthermore, cutting portions 312a and 312b are formed in the runner 301, as indicated by dotted lines. Cutting portions 312a and 312b are thinner than the other portions and can be easily cut by pulling. Therefore, by pulling the runner 301 in the left-right direction after the connecting part 200 is formed, the cutting portions 312a and 312b are cut, dividing the runner 301 into left and right halves, and the portions 311a and 311b can be pulled out from the connecting part 200.

[0035] FIG. 4(b) shows runner 302, which is formed in a second molding process using a synthetic resin of a second color after runner 301 is formed. Runner 302 has portions 321a and 321b formed to fill the front and rear holes of connecting part 200. Like portions 311a and 311b, portions 321a and 321b are molded by pouring a second synthetic resin into a mold from two different directions (front-to-back). Portions 321a and 321b are not connected at their centers (the center of connecting part 200). Portions 321a and 321b are also not connected to portions 311a and 311b. Therefore, by pulling runner 302 in the front-to-back direction after connecting part 200 is molded, portions 321a and 321b can be pulled out of connecting part 200.

[0036] 4(c) shows runner 303, which is formed in a third molding process using a synthetic resin of a third color after runners 301 and 302 have been formed. Runner 303 has portions 331a and 331b that correspond to the upper and lower holes of connecting part 200, and plate portion 332 formed therein. Plate portion 332 is connected to runner 303 via a gate. Here, portions 331a and 331b differ from portions 311a, 311b, 321a, and 321b in that they form part of connecting part 200 even after molding, and correspond to the upper and lower holes.

[0037] FIG. 4(d) shows a runner 304 formed in a fourth molding step using a fourth-color synthetic resin after the runners 301-303 have been formed. The runner 304 is molded to form the body portion of the connecting part 200. The body portion is formed in a block shape so as to cover each of the portions 311a, 311b, 321a, 321b, 331a, and 331b of the runners 301-303. Therefore, the connecting part 200 is formed by molding at least a portion of a predetermined synthetic resin (here, the first- and second-color synthetic resins, crystalline resin) and then covering it with a different synthetic resin (here, the third- and fourth-color synthetic resins, amorphous resin). The molding of the connecting part 200 is completed by the fourth molding step. When connected to part 300 of model base 110, the left, right, front, and rear holes of connected part 200 are filled with parts 311a, 311b, 321a, and 321b, while the top and bottom holes are exposed. From this state, connected part 200 can be removed from part 300 by pulling out parts 311a, 311b, 321a, and 321b and cutting the gate. Thus, according to this embodiment, a connected part having multiple holes can be provided together with other parts as a single part. Furthermore, by using synthetic resins of different colors in each molding process, connected parts with excellent design can be provided.

[0038] <Modifications of connecting parts> A modified example of the connecting part according to this embodiment will be described with reference to Fig. 5. Fig. 5(a) and (b) show plan views of a portion to which model components are connected.

[0039] The connected part 500 shown in Figure 5(a) is an example of a spherical connected part, unlike the block-shaped connected part 200. As such, the connected part of the present invention is not limited to a block shape and may be formed in other shapes. For example, it may be a sphere, a cylinder, a triangular prism, or other shapes.

[0040] The connecting part 510 shown in FIG. 5(b) has multiple holes on one surface. The connecting part 510 has five holes on each of the top and bottom surfaces and two holes on each of the left, right, front, and rear surfaces. In this way, the connecting part of the present invention may be formed with multiple holes on one surface. In this case, for example, the connecting part 510 can be connected via two connecting terminals to the connecting part 106, which has two holes, provided on the back of the model toy 100 shown in FIG. 1A(b). In this case, the model toy 100 and the decorative part can be connected more firmly than when connected via a single connecting terminal. Furthermore, since multiple holes are available, it is also possible to connect multiple decorative parts.

[0041] <Example of using connecting parts> An example of how the connecting parts according to this embodiment are used will be described with reference to Figure 1A(b) and Figure 6. Figure 6 shows the external front view of a model toy 600.

[0042] As described above, the connecting part 200 according to this embodiment can function as a part for connecting decorative parts, as shown in Fig. 1A(b). While it is possible to connect a decorative part directly to the connecting part 106 of the model toy 100, the connecting part 106 faces the main body of the model toy 100, leaving little space for the decorative part to be located. However, by using a connecting part, more space can be secured, and furthermore, a hole appropriate for the shape of the decorative part to be connected can be selected from multiple holes and used.

[0043] 6 shows a model toy 600 in which connecting parts 601a and 601b are used as elbow joints of arms 103a and 103b, respectively. Thus, according to the present invention, connecting parts can also be used as joints that connect two parts. This is not limited to this embodiment, and connecting parts may also be used for other joints, such as knee joints, neck joints, and hip joints.

[0044] As described above, the model element according to this embodiment is a model element comprising a runner formed through a plurality of molding processes and at least one part connected to the runner, the at least one part being formed by combining portions molded in the respective molding processes and including a connecting part having a plurality of holes formed therein for connecting to other parts. According to the present invention, for example, it is possible to provide a new connecting part formed through a plurality of molding processes.

[0045] <Modification> The present invention is not limited to the above-described embodiments, and various modifications and variations are possible within the scope of the invention. For example, the shape of the model toy is not particularly limited, and may include various shapes such as humans, animals, robots, insects, and dinosaurs. Furthermore, the above-described embodiments have been described using detachable model parts (connected parts) on the back of the model toy as an example, but there is no intention to limit the parts or positions to be attached to the model toy. For example, the parts may be part of other clothing parts, armor parts, weapon parts, etc.
