[0010] 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.

[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 front 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.

[0012] The model toy 100 includes a head 101 that constitutes a main body, a chest 102 indicated by a dotted line area, arms 103a and 103b, a waist 104, and legs 105a and 105b. 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.

[0013] The head 101 is rotatably connected to a chest 102. A right arm 103b and a left arm 103a are further connected to the chest 102 at the sides by shoulder joints, and a waist 104 is connected at the bottom. The waist 104 includes hip joints, and a right leg 105a and a left leg 105b are rotatably connected to the waist 104. The chest 102 is an example of an upper body part (first part) of the model toy 100. The arms 103a, b and legs 105a, b are each an example of a second part.

[0014] The model toy 100 according to this embodiment provides a novel mechanism for the shoulder joint and hip joint. In the following embodiment, the hip joint will be described as an example, but a similar configuration can also be applied to the shoulder joint, so a detailed description of the shoulder joint will be omitted. In addition, the hip joint and shoulder joint are provided symmetrically, but because they have the same configuration, only one of the joints will be described.

[0015] <Upper thigh and hip joint components> The configuration of the upper leg 200 including the movable axis of the hip joint of the left leg 105b of the model toy 100 according to this embodiment will be described with reference to Figure 2. Figure 2(a) shows an exploded perspective view of the left leg 105b of the model toy 100. Figure 2(b) shows an exploded perspective view of the upper leg 200.

[0016] FIG. 2(a) is a perspective view of the left leg 105b, exploded into an upper thigh 200 including a movable axis of the hip joint, a lower thigh 210 including a knee joint, and a foot 220. FIG. 2(b) is an exploded perspective view of the upper thigh 200 of the configuration shown in FIG. 2(a). The upper thigh 200 is composed of parts 201a to 207. Parts 201a and 201b, and 202a and 202b are parts that make up the upper side of the upper thigh. Parts 201a and 201b correspond to the first and second parts, respectively, and engage with each other by sandwiching parts 204 to 206 between them. Parts 202a and 202b are connected to the lower parts of parts 201a and 201b, and constitute the lower side of the upper thigh, and also engage with each other by sandwiching part 203 between them.

[0017] Part 204 is a decorative component that is sandwiched between and rotatably connected to parts 201a and 201b below. Part 204 is attached so that a portion of it is exposed from the back of upper leg 200. Part 204 can be rotated in the up and down directions of model toy 100.

[0018] Parts 205 and 206 are rotatably combined with each other to form a movable axis of the hip joint. This movable axis is sandwiched between the upper parts 201a and 201b and rotatably connected. Parts 205 and 206 are combined to form a spherical connecting part (first connecting part), from which two rod-shaped connecting parts (second connecting part and third connecting part) are formed in different directions. One rod-shaped connecting part (second connecting part) is exposed from the opening of part 201a and is rotatably connected to waist 104 of model toy 100. The other rod-shaped connecting part (third connecting part) extends from the spherical connecting part in the z direction (horizontal direction) of model toy 100 in the drawing, and is sandwiched between parts 201a and 201b to be rotatably connected.

[0019] After the parts 201a to 206 are assembled, the part 207 is connected from the front of the model toy 100. The part 207 is an exterior part for the front of the upper leg 200.

[0020] <Upper thigh assembly configuration> Referring to FIG. 3, the assembly configuration of the upper thigh 200 of the left leg 105b of the model toy 100 according to this embodiment will be described. FIG. 3(a) shows a perspective view of the assembly of parts 204 to 206. FIG. 3(b) shows a perspective view of the assembly of part 201a from the upper thigh 200. FIG. 3(c) shows a perspective view of the upper thigh 200 assembled from parts 201a to 207. Note that the configuration of the right upper thigh and hip joint is similar to that of the left upper thigh and hip joint described below, and therefore will not be described here. Also, for ease of explanation, the assembly order of the parts will be described in a different order from the correct assembly order. For example, normally, parts 201a and 201b are assembled together, followed by parts 202a, 202b, and 207. However, please note that in this example, in order to prioritize a detailed description of the configuration of the upper thigh 200, the assembly order will be described using a state assembled in a different order from the correct assembly order.

[0021] 3(a) shows how parts 204 to 206 are assembled to an assembly that includes all the parts of upper leg 200 other than parts 201a, 204, 205, and 206. Part 201b has a recess 311 and a cylindrical portion 312 formed on the inside. Recess 311 is a semi-spherical recess that is shaped to rotatably receive the recess formed in part 201a and the spherical connecting portions formed in parts 205 and 206.

[0022] Furthermore, the movable axis formed by parts 205 and 206 is attached in a position in which two rod-shaped connecting portions extend horizontally from a spherical connecting portion in the drawing. One of the rod-shaped connecting portions is generally formed to extend in a direction along the leg, i.e., downward in the drawing, in order to connect the leg. However, by forming the connecting portion with the leg to extend horizontally (a direction different from the direction along the leg), as in the movable axis according to this embodiment, it is possible to ensure a space (predetermined space) in the area indicated by the dotted line.

[0023] Cylindrical portion 312 is formed in the predetermined space and is a connecting portion for rotatably connecting ring-shaped connecting portion 341 of part 204. Part 204 is a decorative part, and is different from the parts that make up the hip joint and upper thigh of model toy 100. According to this embodiment, by connecting the movable shaft while avoiding the predetermined area, it is possible to ensure space for connecting a decorative part such as part 204 without affecting the movement of the hip joint.

[0024] 3(b) shows how part 201a is assembled after parts 204 to 206 have been assembled. First, it can be seen that the rod-shaped connecting parts of the movable shafts of parts 205 and 206 are assembled so as to extend in the z direction (horizontal, forward) in the figure. This rod-shaped connecting part can rotate in the direction of the solid arrow in accordance with the rotational movement of the movable shaft.

[0025] Part 201a is formed with a side wall 313 and an opening 314. Side wall 313 is formed to rotatably receive the spherical connecting portion of the movable shaft, so as to have the same function as recess 311 of part 201b. Unlike part 201b, part 201a is formed with an opening 314 that receives the spherical connecting portion of the movable shaft and through which a rod-shaped connecting portion extending from the connecting portion can be inserted. As indicated by the dotted arrow, the rod-shaped connecting portion passes through opening 314 and is rotatably connected to waist 104 of model toy 100.

[0026] FIG. 3(c) is a perspective view of upper leg 200 in the state shown in FIG. 3(b) with part 201a further attached. It can be seen that the rod-shaped connecting portion of the movable shaft comprised of parts 205 and 206 penetrates through opening 314 in part 201a and is exposed. Part of part 204 is exposed from the back side of upper leg 200. This portion can rotate in the vertical direction in the figure, as indicated by the arrows. Furthermore, the rod-shaped connecting portion exposed from opening 314 of the movable shaft comprised of parts 205 and 206 can rotate in multiple directions, as indicated by the arrows, due to the rotatable connection between parts 205 and 206 and the spherical connecting portion.

[0027] <Configuration of movable shaft> The configuration of the movable shaft of the hip joint of the model toy 100 according to this embodiment will be described with reference to Fig. 4. Fig. 4(a) shows an exploded perspective view of the movable shaft, and Fig. 4(b) shows a perspective view of the movable shaft.

[0028] 4(a), the movable axis of the hip joint according to this embodiment is configured to include parts 205 and 206. Part 205 is configured to include connecting portions 351 and 353, and a hemispherical portion 352. Part 206 is configured to include a connecting portion 361, a hemispherical portion 362, and a recessed portion 363.

[0029] Connecting portion 351 is an example of a second connecting portion and is formed in a rod shape. Connecting portion 351 is rotatably connected to a part of waist portion 104. Connecting portion 361 is an example of a third connecting portion and is formed in a rod shape. Connecting portion 361 is rotatably connected to parts 201a and 201b at the top of upper thigh portion 200.

[0030] Connecting portion 353 of part 205 is rotatably connected to recessed portion 363 of part 206. Therefore, parts 205 and 206 are rotatably connected by the assembled configuration of connecting portion 353 and recessed portion 363. In other words, the movable shaft itself can rotate. Furthermore, by connecting parts 205 and 206, hemispherical portion 352 and hemispherical portion 362 come into contact and are connected to each other, forming a spherical connecting portion (first connecting portion).

[0031] In FIG. 4(b), the rotation directions of the movable shaft are indicated by arrows. Arrow y1 indicates the direction in which the rod-shaped connecting portion 351 rotates relative to the connected waist portion 104. Arrow y2 indicates the rotation direction of the movable shaft itself. Arrow y3 indicates the direction in which the spherical connecting portion formed by the hemispherical portions 352 and 362 rotates relative to the parts 201a and 201b that form the upper thigh portion 200. In this way, the spherical connecting portion can rotate in multiple directions within the limits of the other parts. Arrow y4 indicates the direction in which the rod-shaped connecting portion 361 rotates relative to the parts 201a and 201b of the upper thigh portion 200. In this way, the movable shaft of the hip joint according to this embodiment has various rotation mechanisms and can rotate in various directions.

[0032] <Side cross section of leg> The operation of the shoulder joint according to this embodiment will be described with reference to Fig. 5. Fig. 5 shows a side cross-sectional view of the left leg 105b. The configuration of the right leg 105a is similar to that of the left leg 105b, so a description thereof will be omitted.

[0033] As described above, the movable shaft 501 that forms the hip joint according to this embodiment is formed on the upper part. In addition, movable shafts 502 and 503 that form the knee joint are arranged one above the other near the knee of the model toy 100. The upper leg part 200 can be rotated around the movable shaft 502. Furthermore, the movable shaft 503 can be rotated relative to the lower leg part 210, and the part including the upper leg part 200 and the movable shaft 502 that are connected to its upper part can be rotated around the movable shaft 503.

[0034] Furthermore, a movable shaft 504 that constitutes an ankle joint is provided on the foot 220. The foot 220 can be rotated around the movable shaft 504. In this way, the leg 105b according to this embodiment can rotate using multiple joints, enabling more natural movement to be achieved.

[0035] Furthermore, the leg 105b according to this embodiment is configured to include a movable shaft 505. The part 204, which is an ornamental component, can be rotated relative to the upper thigh 200 around the movable shaft 505. This is achieved by connecting the connecting portion 361 of the movable shaft 501 to the parts 201a and 201b of the upper thigh 200 in the z direction (horizontal direction) in the figure, thereby securing a predetermined area indicated by the dotted line. In other words, by securing a predetermined area, it is possible to ensure space for assembling the part 204 in a rotatable manner. This allows the part 204 to rotate around the movable shaft 505 without coming into contact with the movable shaft 501. As such, according to this embodiment, the rotation mechanism of the clothing component can be provided near the hip joint without affecting the rotation mechanism of the leg.

[0036] <Movable axis> With reference to Figure 6, the assembly configuration of the movable shafts of the shoulder joint and hip joint for comparison and the assembly configuration of the movable shafts of the shoulder joint and hip joint according to this embodiment will be described. Figures 6(a) and 6(b) show front views of the model toy. Figure 6(a) shows the assembly configuration of the movable shaft for comparison. Figure 6(b) shows the assembly configuration of the movable shaft according to this embodiment. Note that only the right-side configuration of the shoulder joint and hip joint will be shown and described here, but the same applies to the left-side configuration.

[0037] As shown in Figure 6(a), the comparative model toy 600 includes a shoulder joint movable axis 610 and a hip joint movable axis 620. These movable axes connect the arms and legs to the chest and waist, respectively, and it can be seen that the connecting parts extend downward (vertically). In this case, each movable axis is located above the upper arms and upper thighs, respectively, but because the connecting parts extend downward, it is difficult to secure space below the movable axes to incorporate other members (other parts).

[0038] On the other hand, as shown in FIG. 6(b), the model toy 100 according to this embodiment includes a shoulder joint movable shaft 110 and a hip joint movable shaft 120. These movable shafts connect the arms and legs to the chest and waist, respectively, and as described above, the connecting portions extend forward (horizontally) rather than along the arms and legs. Each movable shaft is located above the upper arms and upper thighs, respectively, and because the connecting portions extend horizontally, a predetermined space can be secured below the movable shaft. In this embodiment, these predetermined spaces can be used to rotatably incorporate other members.

[0039] As described above, the model toy according to this embodiment includes a movable shaft having a spherical first connecting portion, a second connecting portion and a third connecting portion extending in different directions from the first connecting portion, a first portion to which the second connecting portion is rotatably connected, and a second portion to which the first connecting portion and the third connecting portion are rotatably connected. Furthermore, the third connecting portion is connected to the second portion while avoiding a predetermined space provided in the second portion. Thus, this embodiment provides a novel mechanism for connecting portions in a model toy.

[0040] <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, in the above-described embodiments, the present invention is applied to a hip joint. However, this is not intended to limit the present invention, and these mechanisms may be used in other parts. For example, they may be applied to a shoulder joint or other joints.
