Description

[Technical Field]

[0001] The present invention relates to model toys and model parts. [Background technology]

[0002] In order to realize movements and poses similar to those of humans and animals, doll toys (model toys) include various joints and movable parts. These mechanisms enable a variety of poses to be realized. However, it is difficult to provide a doll toy with the same range of motion as a human due to limitations on the number of joints and the space available for the range of motion. Therefore, in order to realize the movements and poses described above, it is important to expand the range of motion of the joints and the parts connected to them while using fewer joints and parts. Expanding the range of motion allows for more freedom of movement and a variety of poses. Patent Document 1 proposes a quadruped animal doll with a joint structure that enables realistic movements similar to those of a real animal. [Prior art documents] [Patent documents]

[0012] 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.

[0013] 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.

[0014] The model toy (doll body) 100 includes a head 101, an upper body 102, arms 103a and 103b, a waist 104, an ornamental part 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 upper body 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 upper body 102 by a spherical connecting member. A waist 104 is rotatably connected to the lower part of the upper body 102, and the waist 104 includes a waist joint and a hip joint. Legs, including a right leg 106a and a left leg 106b, are rotatably connected to the hip joints.

[0015] In the following, the structure of an arm joint including a shoulder joint and an elbow joint of an arm will be described as a movable part according to this embodiment. However, this is not intended to limit the present invention, and the movable part described below is not limited to an arm joint, and can also be applied to other joint parts, such as leg joints including a hip joint and a knee joint.

[0016] <Arm configuration> Next, with reference to Figure 2, a detailed configuration of the arm 103b including the arm joint of the model toy 100 according to this embodiment will be described. Figure 2(a) shows the front appearance of the model toy 100. Figure 2(b) shows an exploded perspective view of a group of parts including multiple parts that make up part of the arm 103b. Figure 2(a) is a view similar to Figure 1(a), so its explanation will be omitted. Furthermore, the configuration of the arm 103a is similar to that of the arm 103b, so its explanation will be omitted.

[0017] Reference numeral 200 denotes the range from the upper arm to the wrist of arm 103b. FIG. 2(b) shows an exploded perspective view of the multiple parts that make up part 200. Part 200 of arm 103b is composed of parts 201a to 207 and is rotatably connected to upper body 102. Parts 201a and 201b correspond to the first and second parts, respectively, and fit together to form the sleeves of clothing, which are clothing parts that cover the upper arms. Parts 201a and 201b also fit together, sandwiching parts 202 and 203 between them.

[0018] Parts 202 and 203 are parts that form movable axes, and are connected to parts 201a and 201b so that they can rotate independently. Here, being able to rotate independently means that, for example, when part 202 rotates relative to parts 201a and 201b, part 203 itself can move independently without rotating in conjunction with or following part 202. Note that both parts 202 and 203 are connected to parts 201a and 201b, and when parts 201a and 201b rotate around part 202 as a movable axis, part 203 also rotates indirectly. Part 202 is an example of a first movable axis and a first movable unit, and forms a shoulder joint that is rotatably connected to upper body 102. Part 203 is an example of a second movable axis and a third movable unit, and is a movable axis located between the shoulder joint and elbow joint of model toy 100, and is a part that expands the range of motion of the shoulder joint.

[0019] Part 203 is further rotatably connected to one end of part 204. Parts 205 and 206 that constitute an elbow joint are connected to the other end of part 204. Parts 205 and 206 correspond to the third movable shaft and the second movable part, and are rotatably connected to each other. Part 206 is further rotatably connected to part 207 that corresponds to the forearm.

[0020] <Arm assembly configuration> Next, the assembly configuration of the arm according to this embodiment will be described with reference to Figures 3 and 4. Figures 3(a) and 3(b) show exploded perspective views of the upper arm, and Figure 3(c) shows some of the upper arm parts assembled. Figure 4 shows how the forearm is connected to the upper arm.

[0021] FIG. 3(a) shows an exploded perspective view of parts 201a, 202, and 203, and FIG. 3(b) shows a perspective view of part 201b, which is assembled to these parts. Part 201a is a part that constitutes the sleeve portion and includes a fitting portion 301, a recess 302, and an opening 303. Part 201b is a part that constitutes the sleeve portion and fits with part 201a and includes a fitting portion 304, a recess 305, and an opening 306. Part 202 is a first movable axis that constitutes the shoulder joint and includes a spherical connecting portion 311 that is the first connecting portion and a ring-shaped connecting portion 312 that is the second connecting portion. Part 203 is a second movable axis that serves as a movable axis inside the sleeve portion and includes a cylindrical connecting portion 321 that is the third connecting portion and a rod-shaped connecting portion 322 that is the fourth connecting portion.

[0022] As shown by the dashed lines in FIGS. 3(a) and 3(b), first, fitting portion 301 of part 201a is inserted into the ring-shaped hole in connecting portion 312 of part 202. One end of the cylindrical shape of connecting portion 321 of part 203 is rotatably inserted into recess 302 of part 201a. Meanwhile, the other end of the cylindrical shape is rotatably inserted into recess 305 of part 201b. In this way, both ends of the cylindrical shape of connecting portion 321 are rotatably connected to the recesses formed in parts 201a and 201b, respectively. Therefore, part 203 can rotate relative to parts 201a and 201b around connecting portion 321 as the rotation axis.

[0023] FIG. 3(c) shows a state in which parts 202 and 203 are fitted into part 201a. In this state, part 201b further fits into part 201a, sandwiching parts 202 and 203. At this time, fitting portion 304 of part 201b is inserted into the ring-shaped hole in connecting portion 312 of part 202 and fits into fitting portion 301 of part 201a. Furthermore, the other cylindrical end of connecting portion 321 of part 203 is rotatably inserted into recess 305 of part 201b. In this state, connecting portion 311 of part 202 is assembled so as to be exposed to the outside from openings 303 and 306 of parts 201a and 201b. The exposed connecting portion 311 is rotatably connected to upper body 102.

[0024] As shown in Figure 3(c), parts 202 and 203 are connected to parts 201a and 201b so as to be rotatable in the directions of the arrows y1 and y2, respectively. Here, parts 202 and 203 rotate in the same direction as indicated by the arrows y1 and y2. Therefore, part 203, which is a movable axis inside the sleeve, can expand the range of motion of part 202, which is a shoulder joint.

[0025] FIG. 4 shows a state in which parts 204 to 206 are further connected to the group of parts shown in FIG. 3(c). Part 204 has a cylindrical recess formed therein, and a rod-shaped connecting portion 322 of part 203 is connected to this recess so as to be rotatable in the direction of arrow y3. Furthermore, parts 205 and 206 that form the elbow joint are connected to the bottom of part 204. Parts 205 and 206 are connected to each other so as to be rotatable in the direction of arrow y4. A rod-shaped connecting portion is formed at the bottom of part 206, and part 206 is connected to part 207, which has a cylindrical recess, so as to be rotatable in the direction of arrow y4. Part 207 forms the forearm. Note that although part 201b is shown disassembled in FIG. 4, it may be assembled to parts 201a, 202, and 203, and then parts 204 to 207 may be assembled.

[0026] <Arm movement> The movable structure of arm 103a according to this embodiment will be described below with reference to Fig. 5. Figs. 5(a) to (c) show front views of part of arm 103b. Here, part 201b is shown removed to explain the internal movable axis. Usually, part 201b is assembled together with part 201a so as to cover part of part 202 and part 203, and the sleeve is assembled so that the inside of the sleeve cannot be seen.

[0027] Figure 5(a) shows the normal state in which parts 202 and 203, which are movable axes, are not rotated. From the state shown in Figure 5(a), part 201a is rotated in the direction of arrow y1 around connecting part 312 of part 202. As a result, other parts directly or indirectly connected to part 201a rotate as shown by the dotted arrows in Figure 5(b).

[0028] FIG. 5(c) shows a state in which the arm has been further rotated in the direction of arrow y2 from the state shown in FIG. 5(b) around the connecting portion 321 of part 203 as the movable axis. As shown by the dotted arrow in FIG. 5(c), part 203 rotates relative to part 201a, and other parts directly or indirectly connected to part 203 also rotate. This rotational movement takes place in the space surrounded by the inner wall of the sleeve part of part 201a shown in l1. Thus, according to this embodiment, in addition to the rotation by the shoulder joint shown in FIG. 5(b), rotation can also be performed around part 203, located inside the sleeve part, as the movable axis, thereby expanding the range of motion.

[0029] Note that part 203, which serves as the movable axis, is a joint not found in an actual human, but it is covered by parts 201a and 201b, which correspond to the sleeves of the clothing parts (decorative parts) that cover the upper body 102 of the model toy, and cannot be seen from the outside. In Figures 1(a) and (b), the connecting part 321 of part 203 is shown by a dotted line, and it can be seen that it is covered by the sleeve part, which is an external part of arm 103b. Furthermore, because rotation is limited to within the range inside the sleeve, it does not give the impression of being unnatural, such as bending partway up the upper arm.

[0030] <Cross-section of upper body> A cross section of the upper body according to this embodiment will be described with reference to Fig. 6. Fig. 6 shows a front cross section of the upper body 102, arms 103a and 103b, and waist 104 of the model toy 100. Here, the configuration of arm 103b will be described, but the configuration of arm 103a is similar.

[0031] As described above, in the model toy 100 according to this embodiment, the arm 103b has a movable axis between the shoulder joint and the elbow joint. As shown in FIG. 6, at the shoulder joint, the connecting part 311 of the part 202 is connected to the torso 102 so as to be rotatable in the direction of the arrow y7. Note that while the arrow y7 is shown in two directions in FIG. 6, the connecting part 311 is spherical and can actually rotate in multiple directions. At the shoulder joint, the arm 103b can also be rotated in the direction of the arrow y1 by the connecting part 312.

[0032] Part 203, which is a part inside the sleeve portion, is not directly connected to part 202, and can rotate in the direction of arrow y2 around connecting part 321 as a rotation axis, independently of the rotation of part 202. Furthermore, rod-shaped connecting part 322 of part 203 is connected to a cylindrical recess formed at one end of part 204 so as to be rotatable in the direction of arrow y3. Part 205, which constitutes an elbow joint, is connected to the other end of part 204. Part 205 is rotatably combined with part 206, and they can rotate relative to each other in the direction of arrow y4, allowing arm 103b to bend.

[0033] Part 206 is further connected to part 207, which forms the forearm. A part that becomes a wrist joint is connected to the other end of part 207 so as to be rotatable in the direction of arrow y5. The wrist joint part can be further bent in the direction of arrow y6, and a part that corresponds to the hand is further connected to it.

[0034] As described above, the arm 103b according to this embodiment has many movable mechanisms. In particular, it has a movable mechanism that can rotate inside the sleeve between the shoulder joint and the elbow joint. This allows the model toy 100 according to this embodiment to have an expanded range of motion with fewer parts without creating an unnatural impression.

[0035] As described above, the model toy according to this embodiment includes a first movable shaft having a first connecting portion and a second connecting portion, a second movable shaft having a third connecting portion and a fourth connecting portion, a first part to which the second connecting portion of the first movable shaft and the third connecting portion of the second movable shaft are individually and rotatably connected, and a second part that fits with the first part and covers the first movable shaft by sandwiching it between the first part and the second movable shaft. Thus, according to this embodiment, it is possible to provide a mechanism for realizing a novel structure for expanding the range of motion in, for example, a model toy.

[0036] <Modification> The present invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the invention. In the above-described embodiment, an example in which a movable axis for expanding the range of motion of the shoulder joint is provided between the shoulder joint and the elbow joint has been described, but this is not intended to limit the present invention, and the invention may be used in other locations. For example, the present invention may also be applied to a configuration in which a movable axis for expanding the range of motion of the hip joint is provided between the hip joint and the knee joint. In this case, it is desirable that the movable axis be hidden by clothing parts (decorative parts) that cover the legs.

[0037] Furthermore, although an example of a model toy has been described, the shape of the model toy (doll body) is not particularly limited and includes various shapes such as people, animals, robots, insects, dinosaurs, imaginary life forms, etc. Furthermore, the shape of the model toy is not particularly limited as long as it has a form that includes movable parts.
