[0011] 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.
[0012] First Embodiment <Appearance of the model toy> A first embodiment of the present invention will be described below. First, an example of the external configuration of a model toy 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1(a) shows the external front view of the model toy 100. Fig. 1(b) shows the external side 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.
[0013] The model toy (doll body) 100 includes a head 101, a chest 102, arms 103a and 103b, an abdomen 104, clothing accessories 105, and legs 106a and 106b. The model toy 100 is a movable model toy such as a movable figure, and each part can be moved within a limited range created by its relationship with other members. The head 101 is connected to the chest 102 by a spherical connecting member (hereinafter also referred to as a ball joint). Arms 103, including a right arm 103a and a left arm 103b, are further connected to the chest 102 by spherical connecting members, and the abdomen 104 is connected to the lower part. The detailed configuration of the chest will be described later. Clothing accessories 105 are connected to the abdomen 104. Legs, including a right leg 106a and a left leg 106b, are connected to the lower part of the abdomen 104.
[0014] According to this embodiment, the face of the head 101 is detachable, and multiple set parts can be attached by switching between them. This allows faces with a variety of expressions to be realized. The multiple set parts may include facial parts and eye parts, mouth parts, nose parts, and the like that are attached to each facial part. In this embodiment, by changing the corresponding parts for each set of parts, it is possible to create expressions that give a more natural impression. However, this does not limit the present invention, and only some parts (e.g., teeth parts) may be changed between sets or within a set. The following describes, as an example, a set of parts including facial parts and mouth parts.
[0015] <Head structure> The detailed configuration of the head 101 of the model toy 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2(a) shows the front view of the exterior, similar to Fig. 1(a). Fig. 2(b) shows an exploded perspective view of the multiple parts that make up the head 101. Fig. 2(a) is similar to Fig. 1(a), so its description will be omitted.
[0016] As shown in FIG. 2(b), the head 101 is made up of parts 201 to 211, and is rotatably connected to the chest 102 via part 208. Part 201 corresponds to the first part and is the face part of the model toy 100. Part 202 corresponds to the second part and is a teeth part that constitutes part of the mouth part, and is attached to the back side of part 201. Part 203 corresponds to the third part and is an oral cavity part that constitutes part of the mouth part, and is attached to the back side of part 201 by sandwiching part 202.
[0017] Part 204 is a base part for the head 101, to which face parts, hair parts, and back of the head parts are attached. A face part made up of parts 201 to 203 is attached to the front of part 204. Furthermore, parts 209 and 210 constituting the bangs are attached to these parts from the front, and part 211 is fitted in from above. Parts 205 and 206 constituting the hair parts are attached to the left and right sides of part 204, respectively, and part 207 is attached from the rear as the back of the head. Furthermore, a spherical connecting part of part 208 is rotatably connected to part 204 from below. Furthermore, part 208 is rotatably connected to a part of the chest 102.
[0018] <Facial structure> The detailed configuration of the face of the model toy 100 according to this embodiment will be described with reference to Fig. 3. Fig. 3 shows exploded perspective views of face parts 201 to 203, with Fig. 3(a) being a perspective view from the front and Fig. 3(b) being a perspective view from the rear.
[0019] As shown in FIG. 3(a), part 201, which is a facial part, has an opening 301 formed in it to which part 202, a teeth part, and part 203, a mouth part, are attached from the back side of part 201. Parts 202 and 203 are attached to the rear of the part, forming the interior of the oral cavity of model toy 100. Part 202 has a tooth portion 311 that is exposed from opening 301, and its length is adjusted so that its tip is exposed from opening 301. The lower part of part 203 forms the parts of the oral cavity other than the teeth. Therefore, part 311 depends on the size of the opening formed in the facial part, and therefore it is desirable for part 311 to be molded as a set with the facial part.
[0020] As shown in FIG. 3( b), a connecting portion 302 for connecting the parts 202 and 203 is formed on the back surface of the part 201. The connecting portion 302 is formed, for example, in a rectangular shape, and a connecting portion 312 of the part 202, which is formed to match the connecting portion 302, and a connecting portion 321 of the part 203 are fitted together to connect the parts. More specifically, the connecting portions 312 and 321 are each formed to abut against a portion of the inner wall of the rectangular enclosure of the connecting portion 302, and the connecting portions 312 and 321 are formed so that the abutting portions are different. Therefore, the parts 202 and 203 can be fitted into the part 201 at the same time. Furthermore, the part 203 is assembled so as to cover the part 202, but can also be assembled to the part 201 even when the part 202 is removed. In other words, according to this embodiment, the presence or absence of the tooth part 202 can be switched. The impression of the model toy 100 changes depending on the tooth part, so the user can change the presence or absence of the tooth part according to their preference. The assembly of the parts 202 and 203 will be described later with reference to FIG.
[0021] <Mouth part set configuration> The configuration of the set parts of the mouth part according to this embodiment will be described with reference to Figure 4. Figures 4(a) and (b) show the front side of part 203. Figures 4(c) and (d) show the back side of part 202. Figures 4(a) and 4(c) show set parts, and their reference numbers have an "a" suffix. Figures 4(b) and 4(d) show set parts, and their reference numbers have an "b" suffix.
[0022] The differences between parts 203a and 203b are recesses 401 and 403, respectively, and portions 402 and 404 that form the oral cavity. The portions 402 and 404 form the portions of the oral cavity other than the tooth part exposed through the opening 301, and are slightly different in shape to match the tooth part, part 202. Thus, according to this embodiment, parts 201 to 203 are molded as different parts for each set. However, because the parts are relatively small, it is difficult for an assembler to recognize at a glance which parts form a set. Therefore, in this embodiment, for example, by making the positions of the mating portions of parts 202 and 203 different, the difference between them can be easily recognized.
[0023] For example, as described above, recesses 401 and 403 are provided on parts 203a and 203b, respectively, on opposite sides. Correspondingly, protrusions 413 and 415 that fit into recesses 401 and 403 are provided on parts 202a and 202b, respectively, on opposite sides. Therefore, parts 202 and 203 cannot be assembled correctly unless the correct parts are combined for each set. This makes it possible to prevent incorrect parts from being assembled.
[0024] Furthermore, parts 202a and 202b are formed with portions 414 and 416 of different sizes that correspond to the teeth to be formed in the oral cavity. Here, the sizes are adjusted to match the size of opening 301. Details of this size adjustment will be described later with reference to FIG. 5.
[0025] <Facial parts set contents> The contents of the facial part set according to this embodiment will be described with reference to Fig. 5. Fig. 5(a) and Fig. 5(b) show the front appearance of each set when parts 201 to 203 are assembled.
[0026] 5(a) has an opening 301a. A portion 414 of part 202a corresponding to the teeth is exposed through opening 301a. Furthermore, a portion 402 of part 203a forming the oral cavity is also exposed through opening 301a. The vertical length of opening 301a in part 201a is indicated by arrow 511.
[0027] On the other hand, part 201b shown in Figure 5(b) has opening 301b. As indicated by arrow 512, opening 301b is formed with a size longer than the vertical length of opening 301a. Portion 416 of part 202b corresponding to the teeth is exposed from opening 301b. Furthermore, portion 404 of part 203b forming the oral cavity is also exposed from opening 301b.
[0028] Here, it can be seen that, although the vertical lengths of parts 201a and 201b at openings 301a and 301b are different, the portions 414 and 416 corresponding to the teeth exposed through openings 301a and 301b are similar in length and range. This is because the portions of part 202 corresponding to the teeth are adjusted and formed to match the size of opening 301 for each set. On the other hand, if part 202 were a common part without the above-mentioned adjustment, the degree of exposure of the portions corresponding to the teeth would vary depending on the size of opening 301, giving an unnatural impression. According to this embodiment, to avoid giving such an unnatural impression, the length of the portion (teeth portion) exposed through the opening in a predetermined direction is adjusted and formed to match the size of the opening so that it does not change for each set. This allows the facial expression to be changed without giving an unnatural impression.
[0029] In this embodiment, the tooth parts formed in the upper part of the oral cavity are adjusted so that a certain portion is exposed regardless of the size of the opening. However, the present invention does not intend to limit the shape of the tooth parts. In this embodiment, a configuration having only upper teeth is described, but a configuration having both upper and lower teeth is also possible. Furthermore, the tooth parts themselves may be varied in various ways. For example, a set of parts may be provided in which the shape of the portion exposed to the user's eyes from the outside is a double tooth, a missing tooth, a missing tooth, a jagged tooth, or the like. Alternatively, in the present invention, a single set of parts may include multiple tooth parts with different shapes of the area exposed from the opening. In other words, according to the present invention, rather than changing the tooth parts for each set, other parts may be common parts, and only certain parts, such as tooth parts, may be changeable.
[0030] <With or without teeth parts> The presence or absence of tooth parts according to this embodiment will be described with reference to Figures 6 and 7. Figures 6(a) and 6(b) show side cross sections when parts 201 to 203 are assembled.
[0031] FIG. 6(a) shows the assembled state of parts 201, 202, and 203. On the other hand, FIG. 6(b) shows the assembled state of parts 201 and 203 with part 202 removed. Comparing FIG. 6(a) and FIG. 6(b), it can be seen that the assembled position of part 203 does not change depending on whether part 202 is present or not. As shown in FIG. 6(b), part 203 is assembled to part 201 with a predetermined gap for part 202 to be assembled thereto. Therefore, part 202 is molded to fit into the predetermined gap. This is to avoid an unnatural impression caused by the position of oral cavity parts changing depending on the presence or absence of teeth. The detailed assembly configuration will be explained using FIG. 7.
[0032] 7A and 7B show the procedure for assembling parts 201 to 203, including tooth parts, according to this embodiment. Fig. 7A shows an exploded perspective view of parts 201 to 203 from the rear. A protrusion 701 is formed inside the connecting part 302 of part 201. The protrusion 701 is fitted into an opening 702 formed in part 202.
[0033] FIG. 7(b) shows the state when only part 202 is assembled to part 201. As shown in FIG. 7(b), it can be seen that protrusion 701 protrudes through opening 702 of part 202. In this way, protrusion 701 protrudes rearward beyond part 202 even when part 202 is assembled. The protruding portion of protrusion 701 is further fitted into opening 703 provided in part 203. In this way, part 203 can be assembled to part 201 regardless of whether part 202 is present or not.
[0034] As described above, the model toy according to this embodiment includes a first part having an opening, a second part attached to the back side of the first part and partially exposed through the opening, and a third part attached to the back side of the first part and partially exposed through the opening, sandwiching the second part between the first part and the third part. Furthermore, the second part can be removed from the first and third parts and assembled. This embodiment thus realizes a novel structure for facial parts with changeable facial expressions.
[0035] <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. In the above-described embodiments, an example in which the movable structure is applied to a shoulder joint has been described, but this is not intended to limit the present invention, and the structure may be used in other parts. For example, while the example of a model toy has been described as a model toy, the shape of the model toy (doll body) is not particularly limited, and may include various shapes such as humans, animals, robots, insects, dinosaurs, and imaginary creatures. Furthermore, the shape of the model toy is not particularly limited as long as it includes a movable part.
