[0002] This invention relates to model toys and joint structures. Background Technology
[0003] To achieve movements and postures similar to those of humans and animals, model toys (human figures) include various joints and movable parts. These mechanisms allow for a wide variety of poses. In addition to the main body that enables these movements, the human figure also includes weapons, armor, propellers (propulsion devices), etc. (hereinafter, these components are collectively referred to as "decorative parts"). These decorative parts are attached to the main body, or at least partially assembled to it, which raises concerns about narrowing the movable area of the main body. Therefore, it is desirable for these decorative parts to move in conjunction with parts of the main body, such as arms and legs.
[0004] Patent Document 1 proposes a humanoid figure that complicates the movement of armor corresponding to the movement of the limbs, giving the armor's movement a realistic feel. In this humanoid figure, armor covering a side different from the main body is disposed on the limbs connected to the main body via joint mechanisms. This armor is connected to the upper body via ball joints for free rotation and is also connected to the limbs via rotatable connecting parts. Thus, armor that moves in accordance with the movement of the limbs is realized.

[0024] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Furthermore, the following embodiments are not intended to limit the invention protected by the claims, and the combinations of features described in the embodiments are not necessarily essential to the invention. Two or more features from the plurality of features described in the embodiments may be arbitrarily combined. Additionally, the same or identical structures are labeled with the same reference numerals, and repeated descriptions are omitted.
[0025] <Appearance of model toys>
[0026] First, refer to Figure 1 Here is an example illustrating the appearance structure of the model toy 100 according to this embodiment. Figure 1 (a) indicates the front view of model toy 100. Figure 1 (b) indicates the side view of the model toy 100. Furthermore, the arrows pointing up / down, left / right, and forward / backward indicate the orientation of the model toy in the figure, as do the other figures.
[0027] The model toy 100 includes a head 101, a torso 102, arms 103a and 103b, and legs 104a and 104b forming the main body. Furthermore, the model toy 100 includes a thruster 105 as a decorative element. In this embodiment, a humanoid robot is described as an example of a model toy, but this does not limit the scope of the invention. The invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and decorations.
[0028] The head 101 is connected to the torso 102. The torso 102 is also connected to the right arm 103b and left arm 103a on its sides via connecting members, and to the right leg 104b and left leg 104a at its lower part. Thrusters 105 are propulsion devices for the humanoid robot, located on the back of the knee joints of the right leg 104b and left leg 104a, respectively. Here, the illustration shows a thruster located on the left leg 104a, but the same thruster is also located on the right leg 104b.
[0029] <Leg Structure>
[0030] Next, refer to Figure 2 The structure of the left leg 104a of the model toy 100 of this embodiment will be explained. Figure 2 (a) represents a side view of the left leg 104a. Figure 2(b) represents an exploded side view of the left leg 104a. The structure of the left leg 104a is described here, but the structure of the right leg 104b is omitted since it is the same as that of the left leg 104a.
[0031] like Figure 2 As shown in (b), Figure 2 The left leg 104a shown in (a) is assembled by connecting three parts 201 to 203. Each of the three parts 201 to 203 comprises multiple components. Part 201 corresponds to a portion of the thigh from the hip joint of the model toy 100. Part 202 is configured to include a knee joint and a portion of the thigh and lower leg connected to the knee joint. Part 203 corresponds to the left foot.
[0032] As shown by the dotted line, part 201 is rotatably connected to part 202, and part 203 is also rotatably connected to part 202. In addition, a thruster 105, which serves as a decorative part, is rotatably assembled on the back side of the knee of part 202.
[0033] <Structure of the joint>
[0034] Next, refer to Figure 3 The structure of the joint of the model toy 100 in this embodiment will be explained. Figure 3 (a) indicates that with Figure 2 (b) An exploded side view of the same leg 104a. Figure 3 (b) indicates the composition Figure 3 An exploded perspective view of part 202 of the knee joint shown in (a).
[0035] Here, it is explained that it is equivalent to Figure 3 Further breakdown of the portion 202 around the knee joint of the left leg 104a shown in (a). Figure 3 As shown in (b), part 202 is configured to include multiple fittings 301 to 309. Fittings 301 to 303 constitute the pusher 105 as a decorative part. In addition, fitting 306 constitutes part of the thigh portion of the left leg 104a. Fitting 306 is composed of multiple fittings. Fitting 309 constitutes the shin portion of the left leg 104a. Fitting 307 corresponds to the component around the Achilles tendon of the left leg 104a. Fitting 308 is assembled to fitting 307, and fitting 308 has a recess for connecting to part 203 as the left foot.
[0036] Accessories 304 and 305 are positioned opposite each other, clamping other accessories 301-303 and 306-309, and constitute part of the knee joint and lower leg. Accessories 304 and 305 constitute the first part. Accessory 306, as the second part, is rotatably connected to the first part. Additionally, a thruster 105, configured to include accessories 301-303, which constitute the third part, is rotatably connected to the first part. Details of the operation will be described later.
[0037] <Joint assembly structure>
[0038] Next, refer to Figure 4 The assembly structure of the knee joint and the thruster of the model toy 100 of this embodiment will be explained. Here, the assembly structure of the first part, the second part, and the third part surrounding the knee joint of the left leg 104a will be explained.
[0039] As described above, the two fittings 304 and 305 of Part 1 are arranged opposite each other and assembled in a manner that sandwiches the fittings of Part 2 and Part 3, etc. Fittings 304 and 305 have a left-right symmetrical structure, and here, the structure of fitting 304 will be described with focus. Fitting 304 has recessed portions 403a and 405a and a groove 404a that serve as recesses for rotatably connecting the various fittings. Fitting 305 also has these recessed portions, namely, recessed portions 403b and 405b and a groove 404b.
[0040] Additionally, cylindrical portions 406a and 406b are formed on the left and right sides of accessory 306, which is part 2. Figure 4 In the diagram, the right-side cylindrical portion 406a is not shown, but it is arranged symmetrically with the left-side cylindrical portion 406b. The cylindrical portions 406a and 406b are rotatably connected to the receiving portions 405a and 405b, respectively. Thus, the accessory 306, as part 2, is rotatably connected to part 1.
[0041] As described above, the propeller 105, as the third part, is configured to include fittings 301 to 303. Fitting 301 corresponds to a connecting part and has cylindrical portions 401a and 401b on the left and right sides, respectively. Figure 3 The cylindrical portions 407a and 407b are shown. Accessory 302 corresponds to accessory 1, such as... Figure 3As shown, the fitting 302 has notches 408a and 408b for accommodating cylindrical portions 401a and 401b. The cylindrical portions 401a and 401b are rotatably inserted into the notches 408a and 408b, allowing the fitting 302 to rotate relative to the fitting 301 within the limits imposed by other components. Furthermore, the portions of the cylindrical portions 401a and 401b of the fitting 301 protruding from the notches 408a and 408b are rotatably connected to the receiving portions 403a and 403b of the fittings 304 and 305.
[0042] Accessory 303 corresponds to the second accessory and has protrusions 402a and 402b on the left and right sides. Additionally, accessory 303 has receiving portions (not shown) that are rotatably connected to the cylindrical portions 407a and 407b of accessory 301. The protrusions 402a and 402b are connected to the grooves 404a and 404b of accessories 304 and 305 in a manner that allows them to slide along these grooves.
[0043] Therefore, accessory 301 is connected to accessories 304 and 305 in a manner that allows the cylindrical portions 401a and 401b to rotate as a pivot, and accessories 302 and 303 connected to accessory 301 can rotate in response to the aforementioned rotation of accessory 301. Furthermore, the actuator 105, including accessory 303, is connected in a manner that allows it to slide in the vertical direction of the model toy 100. In the actuator 105, accessory 302 (as the first accessory) and accessory 303 (as the second accessory) are rotatably connected to accessory 301, which serves as the connecting portion. Therefore, accessories 302 and 303 can rotate around accessory 301, and can move between an open state where accessories 302 and 303 are far apart and a closed state where accessories 302 and 303 are close together. Furthermore, "close together" here does not necessarily mean that accessories 302 and 303 are in complete contact; it can also indicate a state of closeness within a predetermined range.
[0044] <Joint rotation movement>
[0045] Next, refer to Figure 5 This describes the rotational motion of the knee joint and thruster of the model toy 100 in this embodiment. Figure 5 (a) represents a side view of the accessory 304, which is part 1, connected to the accessory 306, which is part 2, and the thruster 105, which is part 3, connected to the accessory 304, which is part 1. Figure 5 (b) represents the side view of accessory 304. Figure 5 (c) and (d) indicate the rotational motion of each part relative to part 1.
[0046] like Figure 5As shown in (b), fitting 304 has receiving portions 403a, 405a and a groove 404a, and each part is rotatably connected to these receiving portions 403a, 405a and groove 404a. The arrows in the figure indicate the rotation direction of the connected parts. Figure 5 (a) indicates the normal state in which the parts are connected to the fitting 304.
[0047] Figure 5 (c) indicates from Figure 5 The state of (a) causes the second part to rotate relative to the first part. For example... Figure 5 As shown in (c), accessory 306 can rotate in the direction of the arrow about the cylindrical portions 406a and 406b that function as a knee joint.
[0048] Figure 5 (d) indicates from Figure 5 In state (a), the third part rotates relative to the first part. The thruster 105 can rotate relative to the accessories 304 and 305 about the cylindrical portions 401a and 401b of the accessory 301 as rotation axes, and can slide downward along the grooves 404a and 404b of the accessories 304 and 305. In addition, since the accessory 303 is rotatably connected to the accessory 301, it can move towards the closed state, which brings the accessories 302 and 303 closer together. Figure 5 (d) indicates the scenario where these three actions are performed. That is, the following scenario is known: the propeller 105 folds and slides downwards. This ensures more space for the accessory 306 to rotate. In other words, space is ensured on the back side of the knee joint of the model toy 100.
[0049] <Examples of joint movements>
[0050] Next, refer to Figure 6 This describes an example of the movement of the knee joint and propeller of the model toy 100 in this embodiment. Figure 6 (a) and (b) indicate a situation in which at least one of the second and third parts is rotated relative to the first part.
[0051] Figure 6 (a) indicates the case where only the second part rotates relative to the first part. Here, the thruster 105, which is the third part, is in the normal position with its open state. Therefore, it can be seen that for the accessory 306, which is the second part, the movable area up to the position where it contacts the thruster 105 is limited, and the leg bending movement realized by the knee joint is restricted. That is, since the thruster 105 is located in the rotation direction of the accessory 306, the movable area of the accessory 306 is restricted.
[0052] on the other hand, Figure 6(b) indicates the case where accessory 306 is rotated while the thruster 105 is folded down and slid downwards. For example... Figure 6 As shown in (b), space can be secured on the back side of the knee joint, and this space can be used to expand the movable area of accessory 306. Therefore, it can be seen that, with... Figure 6 Compared to (a), in Figure 6 In (b), accessory 306 further rotates relative to accessory 304. Thus, the configuration ensures the movable area of the joint when the pusher 105, serving as a decorative part, is located near the joint (in this case, the knee joint). By ensuring the movable area in this way, greater freedom of movement and a wider variety of postures can be achieved.
[0053] As explained above, the model toy of this embodiment includes: a first part; a second part connected to the first part in a manner rotatable relative to the first part; and a third part located in the direction of rotation of the second part, the third part being connected to the first part in a manner rotatable and slidable relative to the first part. Furthermore, the third part slides in the direction of rotation of the second part, thereby ensuring space for the second part to rotate. Thus, for example, in a model toy, decorative parts can be better provided without restricting the movable area of the model toy's main body, enabling greater freedom of movement and a wider variety of poses.
[0054] This invention is not limited to the embodiments described above, and various modifications and alterations can be made within the scope of the invention's intent. For example, the shape of the model toy is not particularly limited, and includes a wide variety of shapes such as people, animals, robots, insects, and dinosaurs.
