Abstract
Description
[Technical field]
[0001] The present invention relates to a model toy and an articulated structure. [Background technology]
[0002] Model toys (doll bodies) include various joints and movable parts to realize movements and poses similar to those of humans and animals. These mechanisms allow for a variety of poses. In addition to the main body that realizes the above movements, the doll body is also equipped with weapons, protective gear, thrusters (propulsion devices), etc. (hereinafter, these will be collectively referred to as decorative parts). These decorative parts are attached in close contact with the main body or at least partially incorporated therein, which may result in a narrowing of the range of motion of the main body. Therefore, it is desirable for such decorative parts to move in conjunction with the main body, such as the arms and legs.
[0003] Patent Document 1 proposes a doll body in which the movement of the armor according to the movement of the limbs is made complex, and the movement of the armor is made realistic. In this doll body, the limbs are connected to the main body via a joint mechanism, and armor covering the side different from the main body side is arranged on the limbs, and the armor is connected to the upper body via a ball joint so as to be freely rotatable, and is further connected to the limbs via a rotatable connection part. This realizes an armor that moves in accordance with the movement of the limbs. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2014-73325 A Summary of the Invention [Problem to be solved by the invention]
[0005] In the above-mentioned conventional technology, armor is provided along the limbs and arms to follow their movements. On the other hand, in addition to decorative parts provided along the main body, some decorative parts are at least partially incorporated and attached to the main body. For example, they may be rotatably connected to the elbow joint or knee joint. However, such decorative parts are provided in the range of motion of the joint mechanism located nearby, and may limit the movement of the joint mechanism.
[0006] The present invention provides a novel mechanism that leads to an expansion of the range of motion of the main body of a model toy, for example, in a model toy. [Means for solving the problem]
[0007] The present invention is, for example, a model toy comprising a first part, a second part rotatably connected to the first part, and a third part located in the direction in which the second part rotates and connected to the first part via a connecting part, wherein a part of the first part rotates in response to the rotation of the second part, and the third part slides in the direction in which the second part rotates in conjunction with the connecting part which is rotated by the rotation of the part of the first part.
[0008] The present invention also relates to, for example, a joint structure comprising a first part, a second part rotatably connected to the first part, and a third part located in a direction in which the second part rotates and connected to the first part via a connecting part, wherein a part of the first part rotates in response to the rotation of the second part, and the third part slides in the direction in which the second part rotates in conjunction with the connecting part which is rotated by the rotation of the part of the first part.

[0011] 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.
[0012] <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(a) shows the external front view of the model toy 100, and Fig. 1(b) shows the external side view 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 the other figures.
[0013] The model toy 100 includes a head 101, a torso 102, arms 103a and 103b, and legs 104a and 104b that constitute a main body. Furthermore, the model toy 100 includes thrusters 105 as decorative parts. 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 decorative tools.
[0014] The head 101 is connected to a torso 102. A right arm 103b and a left arm 103a are further connected to the torso 102 at the sides by connecting members, and a right leg 104b and a left leg 104a are connected at the bottom. Thrusters 105 are propulsion devices provided on the doll-like robot, and are provided on the backs of the knee joints of the right leg 104b and the left leg 104a, respectively. Here, the thruster provided on the left leg 104a is shown, but a similar thruster is also provided on the right leg 104b.
[0015] <Leg configuration> Next, the configuration of the left leg 104a of the model toy 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2(a) shows a side view of the left leg 104a. Fig. 2(b) shows an exploded side view of the left leg 104a. Here, the configuration of the left leg 104a will be described, but the configuration of the right leg 104b will not be described since it has the same configuration as the left leg 104a.
[0016] The left leg 104a shown in Fig. 2(a) is assembled by connecting three parts 201-203 as shown in Fig. 2(b). Each of the three parts 201-203 is composed of a plurality of members. The part 201 corresponds to a part of the part from the hip joint to the upper leg of the model toy 100. The part 202 is composed of a knee joint and a part of the upper leg and lower leg parts connected to the knee joint. The part 203 corresponds to the left foot.
[0017] As indicated by the dotted lines, part 201 is rotatably connected to part 202, and part 203 is also rotatably connected to part 202. In addition, thruster 105, which is a decorative part, is rotatably attached to the back side of the knee of part 202.
[0018] <Joint structure> Next, the configuration of the joint of the model toy 100 according to this embodiment will be described with reference to Fig. 3. Fig. 3(a) shows an exploded side view of the leg 104a similar to Fig. 2b. Fig. 3(b) shows an exploded perspective view including the parts 201 and 202 that constitute the knee joint shown in Fig. 3(a).
[0019] Here, further disassembly of the parts 201 and 202 corresponding to the periphery of the knee joint of the left leg 104a shown in FIG. 3(a) will be described. As shown in FIG. 3(b), the parts 201 and 202 are configured to include a plurality of parts 301 to 308. The part 301 is configured to include the upper leg part, the lower leg part, and the base of the knee joint of the left leg 104a, and the thruster 105. The parts 302 to 308 are assembled to the part 301 as shown by the dotted lines. Specifically, the parts 302 and 303 are assembled to cover the front of the lower leg part of the left leg 104a. The parts 304 and 305 are assembled to face each other so as to sandwich the lower leg part of the left leg 104a from both sides, and constitute a part of the lower leg part. The parts 306 to 308 are assembled to cover the sides of the upper leg part of the left leg 104a, and constitute a part of the upper leg part.
[0020] <Joint assembly configuration> Next, the assembly configuration of the knee joint and thruster (part 301) of the model toy 100 according to this embodiment will be described with reference to Fig. 4. Here, the assembly configuration of the first part, the second part, and the third part constituting the periphery of the knee joint of the left leg 104a will be described.
[0021] The parts 403a and 403b form a knee joint. A lower leg part, which is a first part, and an upper leg part, which is a second part, are connected to the knee joint. Here, a part 406 is rotatably connected to the knee joint as a part of the lower leg part, and a part 407 is rotatably connected to the knee joint as a part of the upper leg part. One side of a part 401, which is a connecting part, is further rotatably connected to the part 406. In addition, the other side of the part 401 is rotatably connected to the thruster 105, which is a decorative part, via parts 402a and 402b. As a result, the part 401 connects the part 406, which is a part of the first part, and the thruster 105, and rotates following the rotation of the knee joint. Therefore, the thruster 105 connected to the part 401 also moves following the rotation of the knee joint. Details of these operations will be described later.
[0022] The thruster 105 is rotatably connected to a connecting part, part 401, via parts 402a and 402b. The parts 402a and 402b are rotatably assembled to the part 401 so as to face each other and sandwich the part 401 from both sides. The parts 402a and 402b are further connected to a part 405 that constitutes a part of the lower leg.
[0023] Part 405 and part 406 form part of the lower leg. Part 405 is fixedly attached to parts 304 and 305 that cover both sides of the lower leg. Meanwhile, part 406 is rotatably connected to parts 403a and 403b that form part of the knee joint, and rotates following the rotation of the upper leg about the knee joint. Also, as shown by the dotted line, the lower part of part 406 is slidably connected to a vertical groove formed in part 405.
[0024] <Rotational movement of joints> Next, referring to Fig. 5, the rotational movement of the knee joint and thruster in the model toy 100 according to this embodiment will be described. Fig. 5(a) shows a side view of the configuration including the upper leg part, lower leg part, knee joint, and thruster of the left leg 104a before rotation. Fig. 5(b) shows a side view of the state in which the upper leg part has been rotated around the knee joint. Fig. 5(c) and (d) show the movement of each part that moves in response to the rotation of the upper leg part.
[0025] As shown in Fig. 5(b), part 407 constituting a part of the upper leg part (second part) rotates in the direction of the arrow around the knee joint from the state before rotation shown in Fig. 5(a). In this state, other parts such as part 406 of the lower leg part, part 401, and thruster 105 do not move in response to the rotation of the upper leg part. Also, in the state shown in Fig. 5(b), part 407 is rotated to the maximum of the range of motion around part 403 constituting the knee joint.
[0026] FIG. 5(c) shows a state where a force is applied to part 407 constituting a part of the upper thigh from the state of FIG. 5(b) in a direction to rotate the part around the knee joint. Here, since part 407 has rotated to the maximum extent of its range of motion relative to part 403 in the state of FIG. 5(b), even if a force beyond this is applied, part 407 will not rotate relative to part 403. Meanwhile, part 406 constituting a part of the upper thigh is also connected so as to be rotatable around the knee joint. Therefore, the applied force causes part 403 to rotate relative to part 406 around the knee joint. Furthermore, the force is also transmitted to part 406, and part 406 slides upward as if pulled by the rotation of part 403. As a result, part 406 slides in a direction away from part 405 fixed to another part.
[0027] FIG. 5(d) shows a state where a force is applied to part 407 constituting a part of the upper leg from the state of FIG. 5(c) in a direction to rotate about the knee joint. As a result, parts 403 and 406 rotate further in the same manner as in FIG. 5(c). Part 406 rotates further by being pulled by part 403. As a result, part 401 also rotates as if pulled by the rotation of part 406. As part 401 rotates, thruster 105 connected to part 401 also rotates and slides as shown by the arrow in the figure. That is, thruster 105 rotates as if pulled to the lower leg and further slides downward in the figure. As a result, a space for part 407 constituting a part of the upper leg to rotate can be secured, and part 407 can rotate to the position shown in FIG. 5(d).
[0028] In this way, according to this embodiment, the upper leg part, the lower leg part, and the thruster, which is a decorative part, move in conjunction with each other, and the upper leg part can be rotated into the space created by the rotation and sliding of the thruster. As a result, according to this embodiment, the thruster 105 arranged on the back side of the knee joint moves so as to fold in response to the movement of the knee joint, thereby further expanding the range of motion of the knee joint.
[0029] <Operation of connected parts> Next, the movement of the connecting parts linked to the movement of the knee joint according to this embodiment will be described with reference to Fig. 6. Fig. 6(a) shows a side view of the left leg 104a before rotation. Fig. 6(b) shows a side view of the left leg 104a after rotation. In Fig. 6(a) and Fig. 6(b), the parts 401, 405 and the thruster 105 are shown with solid lines, and the other parts are shown with dotted lines. Also, black circles indicate the connecting parts that serve as the rotation axes of each part.
[0030] Fig. 6(a) is a side view of the configuration including the upper leg part, lower leg part, knee joint, and thruster of the left leg 104a before rotation, similar to Fig. 5(a). As shown in Fig. 6(a), before rotation (first state), the part 401 is in a state in which the connection part with the part 406, which is the first part, and the connection part with the thruster 105, which is the third part, are positioned horizontally. In other words, the part 401, which is the connected part, is positioned horizontally.
[0031] Fig. 6(b) is a side view of the configuration including the upper leg portion, lower leg portion, knee joint, and thruster of the left leg 104a after rotation, similar to Fig. 5(d). As shown in Fig. 6(b), after rotation (second state), the part 401 is in a state in which the connection portion with the part 406, which is the first part, and the connection portion with the thruster 105, which is the third part, are positioned vertically. In other words, the part 401, which is the connected part, is positioned vertically.
[0032] In this way, before and after rotation around the knee joint, part 401 for interlocking the various parts moves from a horizontal position to a vertical position, creating a space in the horizontal direction near part 401. Furthermore, thruster 105 rotates and slides so as to be folded so as to be in close contact with the lower leg portion in the created space. In this way, according to this embodiment, multiple parts rotate in conjunction with the rotation around the knee joint, and the resulting space can be used to expand the range of motion of the upper leg portion around the knee joint.
[0033] As described above, the model toy according to this embodiment includes a first part, a second part rotatably connected to the first part, and a third part located in the direction in which the second part rotates and connected to the first part via a connecting part. A part of the first part rotates following the rotation of the second part, and the third part slides in the direction in which the second part rotates in conjunction with the connecting part that is rotated by the rotation of the part of the first part. This allows, for example, a decorative part to be suitably provided in a model toy without restricting the range of motion of the main body of the model toy, thereby realizing more flexible movements and a variety of poses.
[0034] The present invention is not limited to the above-described embodiment, and various modifications and changes are possible within the scope of the gist of the invention. For example, the shape of the model toy is not particularly limited, and includes various shapes such as people, animals, robots, insects, dinosaurs, etc.
