Description

[Technical field]

[0001] The present invention relates to a model toy and a movable structure. [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 allow for various poses. However, providing a doll toy with the same number of joints as a human or other such body part requires a large number of parts, and even in an elaborate doll toy, the number is limited and it is difficult to realize this. 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 thereto while configuring the doll with fewer joints and parts. By expanding the range of motion, it is possible to perform movements with a higher degree of freedom and a variety of poses. Patent Document 1 proposes a quadruped animal doll having a joint structure that allows realistic movements similar to those of real animals. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-17264 A Summary of the Invention [Problem to be solved by the invention]

[0004] To achieve natural movements like those of human limbs, it is desirable to have the ability to rotate in various directions. On the other hand, by providing joints such as the neck joint, shoulder joint, hip joint, and waist joint inside the body like a human, it is possible to achieve natural movements of the parts connected to those joints, but the range of motion is limited by the adjacent parts. Therefore, in order to expand the range of motion, it is important to secure space between adjacent parts.

[0005] The present invention provides a mechanism for realizing a new structure for expanding the range of motion in, for example, a model toy. [Means for solving the problem]

[0006] The present invention is, for example, a model toy comprising a first part having a movable axis, a second part having a first connecting portion connected to the movable axis, and a third part having a second connecting portion connected to the movable axis, wherein each of the first part, the second part, and the third part is individually rotatable with the movable axis as a rotation axis.

[0007] The present invention is also characterized in that, for example, a movable structure includes a first part having a movable axis, a second part having a first connecting portion connected to the movable axis, and a third part having a second connecting portion connected to the movable axis, and each of the first part, the second part, and the third part is individually rotatable with the movable axis as a rotation axis.

[0010] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0011] <Appearance of the model toy> 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 shows the external side of the model toy 100. Note that the up / down, left / right, and front / rear arrows indicate the orientation of the model toy in the figure, and the same applies to other figures.

[0012] Model toy (also called a doll-type toy or model) 100 comprises a head 101, a neck 102, a body 103, front legs 104, rear legs 105, and a tail 106. Model toy 100 is a movable model toy such as a movable figure, and each part can be moved within a limited area caused by its relationship with other members. Head 101 is connected to neck 102. Body 103 is connected to neck 102. Front legs 104 are connected to the left and right (left front leg and right front leg) in front of body 103, rear legs 105 are connected to the left and right (left hind leg and right hind leg) in the rear, and tail 106 is connected to the rear.

[0013] <Head structure> Next, the configuration of the head 101 of the model toy 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2 shows an exploded perspective view of the head 101.

[0014] Head 101 is configured to include parts 201 to 203. Part 203 corresponds to the first part, part 201 corresponds to the second part, and part 202 corresponds to the third part. Part 201 is a part that forms the upper jaw of head 101. Part 202 is a part that forms the lower jaw of head 101. Part 203 is a part that forms the back of the head 101. Each of parts 201 to 203 is configured to include multiple parts.

[0015] <Assembly configuration> Next, the assembly configuration of the head 101 according to this embodiment will be described with reference to Figures 3 and 4. Figure 3 shows how the lower jaw and the back of the head are assembled. Figure 4 shows how the upper jaw part 201 is further assembled to the assembled parts shown in Figure 3(b).

[0016] 3(a) shows an exploded perspective view of lower jaw part 202 and back of head part 203. Part 202 includes ring-shaped connecting parts 321a and 321b. Each of connecting parts 321a and 321b has a rod-shaped connecting part and is connected to part 202 via said connecting parts. Part 203 includes connecting part 331 which serves as a movable axis. The movable axis is formed in a rod shape and serves as the rotation axis of each of parts 201 to 203.

[0017] Ring-shaped connecting parts 321a and 321b are rotatably connected to connecting part 331, which is a movable shaft, from both ends of the movable shaft. In an actual assembly process, connecting parts 321a and 321b are connected to part 202 after connecting parts 321a and 321b to connecting part 331.

[0018] 3(b) shows the assembled state of parts 202 and 203. The state in which ring-shaped connecting parts 321a and 321b are assembled to rod-shaped connecting part 331 is shown. By assembling parts 202 and 203 in this manner, parts 202 and 203 are connected to each other so as to be rotatable with connecting part 331 as the axis of rotation. Also shown is the state in which both ends of connecting part 331 protrude from the ring parts of connecting parts 321a and 321b (protruding parts).

[0019] Fig. 4 shows how parts in which connecting portions 321a and 321b are assembled to connecting portion 331 are rotatably assembled to part 201. For the purpose of simplification, other portions of parts 202 and 203 are omitted from Fig. 4. Part 201 includes cylindrical connecting portions 311a and 311b having a hollow portion. Connecting portions 311a and 311b each have a hollow space (hollow portion) and are formed so that the protruding portion of connecting portion 331 can be inserted therein.

[0020] The part having coupling parts 321a and 321b assembled to coupling part 331 is rotatably coupled to part 201 by inserting the protruding parts of coupling part 331 into coupling parts 311a and 311b, respectively, as indicated by the dotted arrows. As a result, part 201 is coupled to the parts having coupling parts 321a and 321b assembled to coupling part 331, i.e., parts 202 and 203, so as to be individually rotatable about coupling part 331 as the axis of rotation.

[0021] Note that FIG. 4 shows the state in which connecting portions 331, 321a, and 321b are attached after assembling part 201, which is made up of multiple parts, but in the actual assembly process, assembly is performed by inserting each part having connecting portions 311a and 311b into the above-mentioned protruding portions, and then assembling the other parts included in part 201.

[0022] <Cross section of head> Next, a cross section of the head 101 according to this embodiment is shown with reference to Fig. 5. The cross section shown in Fig. 5 is taken along dotted line AA' in Fig. 1 and viewed from the front.

[0023] 5 shows how two ring-shaped connecting parts 321a and 321b of part 202 are connected to rod-shaped connecting part 331 of part 203. Furthermore, the protruding parts protruding from connecting parts 321a and 321b of connecting part 331 are inserted into cylindrical connecting parts 311a and 311b of part 201, respectively.

[0024] In this way, parts 201 to 203 are connected via connecting portion 331, each of which is formed in a rod shape. Connecting portion 331 functions as a rotation axis, and each part is connected to be rotatable individually. Part 201 has protruding portions at both ends of connecting portion 331 rotatably inserted into cylindrical connecting portions 311a and 311b, respectively. As a result, part 201 is connected to part 203 to be rotatable in the direction indicated by the dotted arrow.

[0025] Furthermore, part 202 has ring-shaped connecting portions 321a and 321b rotatably inserted into rod-shaped connecting portion 331. This allows part 202 to be rotatably connected to part 203 in the direction indicated by the solid arrow. Meanwhile, part 203 is rotatably connected to parts 201 and 202 in the direction indicated by the dashed-dotted arrow.

[0026] <Example of head movement> Next, the movable configuration of the head 101 in the model toy 100 according to this embodiment will be described with reference to Figures 6 and 7. Figure 6 shows the opening movement of the head. Figure 7 shows the looking up movement of the head 101.

[0027] First, the mouth opening movement of the head 101 will be described with reference to Fig. 6. Fig. 6(a) shows a closed state (first state) in which the upper jaw part 201 and the lower jaw part 202 are in contact with each other. Fig. 6(b) shows an open state (second state) in which the parts 201, 202 are separated from each other from the first state of Fig. 6(a). Fig. 6(b) shows the part 202 moving by rotating in the direction of the arrow. In this second state, a part of the part 202 is in contact with a part of the part 203, and thus cannot rotate any further.

[0028] Fig. 6(c) shows an open-mouthed state (third state) in which the degree of opening is even greater than that in Fig. 6(b). In the third state, the part 203 at the back of the head is rotated in the direction of the arrow to ensure a rotation area for the part 202, and the part 202 is further rotated in the direction of the arrow within the ensured area. Thus, when comparing the second state with the third state, it can be seen that the distance between the part 201 and the part 202 is longer in the third state than in the second state.

[0029] Fig. 6(d) shows part 203 in the foreground by a dotted line in the second state shown in Fig. 6(b) to clearly show the positional relationship of part 203. Similarly, Fig. 6(e) shows part 203 in the foreground by a dotted line in the third state shown in Fig. 6(c). In the second state of Fig. 6(d), part 203 is not rotated.

[0030] 6(e) shows a third state in which part 203 is rotated in the direction of the arrow (predetermined direction). In this third state, it can be seen that as part 203 rotates, its tip portion moves so as to enter the inside of part 201. In other words, a rotation area for part 203 is formed in advance inside part 201. By rotating part 203 in this way so as to enter the inside of part 201, the rotation area for part 202 can be expanded.

[0031] Next, the upward movement of the head 101 will be described with reference to Fig. 7. Fig. 7(a) shows a closed state (first state) in which the upper jaw part 201 and the lower jaw part 202 are in contact with each other. Fig. 7(b) shows an open state (fourth state) in which the parts 201, 202 are separated from each other, from the first state in Fig. 7(a). Fig. 7(b) shows the part 201 moving by rotating in the direction of the arrow. In this fourth state, a part of the part 201 is in contact with a part of the part 203, and thus cannot rotate any further.

[0032] Fig. 7(c) shows a state (fifth state) in which part 202 is rotated from the open-mouth state (fourth state) in Fig. 7(b) to the position of part 201, and head 101 looks up. In the fifth state, part 202 is rotated in the direction of the arrow to a position where it abuts against part 201.

[0033] In Fig. 7(d), in the first state shown in Fig. 7(a), part 203 is shown in the foreground by a dotted line to clearly show the positional relationship of part 203. Similarly, in Fig. 7(e), in the fourth state shown in Fig. 7(b), part 203 is shown in the foreground by a dotted line. In the first state of Fig. 7(d), part 203 is not inserted inside part 201.

[0034] On the other hand, the fourth state in Fig. 7(e) shows a state in which part 201 is rotated in the direction of the arrow. In this fourth state, it can be seen that part 201 moves so as to take in the tip portion of part 203 inside part 201 as it rotates. By rotating in this way so as to take in the tip portion of part 203 inside part 201, part 201 can rotate without being restricted by part 203. Note that even in the fifth state in Fig. 7(c) where part 202 is abutted against part 201, part 203 maintains the state of being inserted into part 201.

[0035] As described above, the model toy according to this embodiment includes a first part having a movable shaft, a second part having a first connecting portion connected to the movable shaft, and a third part having a second connecting portion connected to the movable shaft. Each of the first part, the second part, and the third part can rotate independently with the movable shaft as a rotation axis. In this way, the present invention can realize a novel structure for expanding the range of motion in a model toy.

[0036] <Modification> The present invention is not limited to the above-mentioned embodiment, and various modifications and changes are possible within the scope of the gist of the invention. In the above-mentioned embodiment, the movable structure is applied to the temporomandibular joint of the head, but the present invention is not limited to this embodiment, and the movable structure may be used in other parts. For example, the movable structure may be used in a joint structure that has an opening in one part.

[0037] 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 humans, animals, robots, insects, dinosaurs, imaginary life forms, etc. Also, the shape of the model toy is not particularly limited as long as it includes a movable part.
