Description

[0001] This application is a divisional application of an application with an application date of March 14, 2025, an application number of 202510301733.7, and an invention title of "Model Toy and Movable Structure". Technical Field

[0002] The present invention relates to a model toy and a movable structure. Background Art

[0003] In order to achieve movements and postures close to those of humans and animals, various joints and movable parts are included in a model toy (humanoid). Using these mechanisms, various postures can be achieved. In addition to the main body that realizes the above movements, weapons, armor, etc. (hereinafter, these are collectively referred to as decorative parts) are also installed on the humanoid.

[0004] In Patent Document 1, a humanoid is proposed in which the movement of armor corresponding to the movement of a limb is complicated to give a realistic feel to the movement of the armor. In this humanoid, armor that covers a side different from the main body side is disposed on a limb part connected to the main body by a joint mechanism, and the armor is rotatably connected to the upper body by a ball joint and is also connected to the limb part by a rotatable connecting fitting.

[0007] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2014 - 73325 Summary of the Invention

[0008] Problems to be Solved by the Invention

[0009] In the above prior art, the armor provided along the limb part and the arm part follows the movements of the limb part and the arm part. On the other hand, for the decorative parts, in addition to being provided along the main body, there are also decorative parts that are at least partially assembled to the main body for installation. These decorative parts are in close contact with the main body or at least partially assembled to the main body for installation, so the movable area is restricted by the fittings of the main body. Moreover, for the decorative parts that are in close contact with the fittings of the main body, there is less area for gripping when making them move, and it is not easy to perform movements.

[0010] The present invention provides a new structure for a movable mechanism in a model toy, for example.

[0022] Description of Reference Numerals

[0023] 100, model toy; 101, head; 102, upper body part; 103a, 103b, arm parts; 104a, 104b, leg parts. Detailed Description of the Embodiment

[0024] Hereinafter, embodiments will be described in detail with reference to the drawings. It should be noted that the following embodiments do not limit the invention described in the claims. In addition, not all combinations of the features described in the embodiments are necessarily required for the invention. Two or more of the multiple features described in the embodiments can also be arbitrarily combined. In addition, the same reference numerals are assigned to the same or similar structures, and repeated descriptions are omitted.

[0025] <Appearance of the model toy>

[0026] Refer to Figure 1 To describe an example of the external structure of the model toy 100 of this embodiment. Figure 1 This shows the front view of the appearance of the model toy 100. In addition, the arrows of x, y, and z respectively indicate the orientations of the left, upper, and front directions of the model toy. The same applies to other drawings.

[0027] The model toy 100 includes a head 101, an upper body part 102, arm parts 103a and 103b, and leg parts 104a and 104b that constitute the main body part. In this embodiment, as an example of the model toy, a humanoid robot is taken as an example for description, but it is not intended to limit the present invention. The present invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and ornaments.

[0028] The head 101 is connected to the upper body part 102. On the upper body part 102, the right arm part 103b and the left arm part 103a are also rotatably connected to the side part by connecting members. On each arm part 103, an armor as a decoration part is connected to the shoulder part. This armor is assembled to the shoulder joint (joint part) and can be rotated by a rotation mechanism different from the shoulder joint. The lower part of the upper body part 102 includes a hip joint, to which the right leg part 104b and the left leg part 104a are respectively rotatably connected.

[0029] <Structure of the left arm part>

[0030] Refer to Figure 2 To describe the structure of the left arm part 103a of this embodiment. Figure 2 (a) of Figure 2 shows an exploded front view of the left arm part 103a.

[0031] As Figure 2As shown in (a) of , the left arm part 103a is configured to include a shoulder part 201 and an arm part 202. A rotatable armor as a decorative part is connected to the shoulder part 201. In the present embodiment, an example will be described in which the decorative part is mounted on a shoulder configured to include an upper wing, a middle wing, and a lower wing. The decorative part is connected to at least a part of the fittings of the shoulder joint (joint part) included in the shoulder part 201. However, since the rotation mechanism of the shoulder joint and the rotation mechanism of the decorative part are independently configured, the rotations of each are independently performed without affecting each other. In addition, the present invention is not intended to be limited to the illustrated decorative part, and other decorative parts for other uses and shapes may also be used. For example, as the decorative part, a weapon, a protective gear, a clothing part, etc. that can be partially rotated may also be used. In addition, the position where the decorative part is mounted is not intended to be limited.

[0032] As Figure 2 As shown in (b) of , the shoulder part 201 is configured to include fittings 211 to 220. The fittings 211, 212a, 212b, 213a, 213b constitute the rotation mechanism (movable structure) of the decorative part. The fittings 214a, 214b are decorative fittings that connect the movable structure. The fittings 214 to 217 are fittings that are connected to any one of the fittings 211 to 213 to constitute the upper wing, the middle wing, and the lower wing.

[0033] The fittings 218 to 221 are fittings that constitute the shoulder joint. A part of the fitting 218 is inserted into the opening of the fitting 211 of the movable structure that constitutes the decorative part. In this state, the fittings 212a, 212b, 213a, 213b are connected from both side surfaces. In addition, the rotation mechanism of the shoulder joint is constituted by the fittings 219, 220, 221 and is not directly connected to the above-mentioned movable mechanism of the decorative part. Therefore, the rotations of the shoulder joint and the decorative part do not affect each other and can rotate independently.

[0034] <Rotation mechanism of the decorative part (armor)>

[0035] Refer to Figure 3 The rotation mechanism of the decorative part of the model toy of the present embodiment will be described. Figure 3 (a) of shows the front view of the rotation mechanism of the decorative part. Figure 3 (b) of shows the exploded perspective view of the rotation mechanism.

[0036] The decorative part of the present embodiment is configured to include an upper wing, a middle wing, and a lower wing. In Figure 3In the rotating mechanism shown in (a), the fittings 216 and 217 corresponding to the upper wings are connected to the fitting 211, the fitting 215 corresponding to the middle wings is connected to the fitting 213b, and the fitting 214 corresponding to the lower wings is connected to the fitting 212b. According to the present embodiment, the upper wings and the lower wings can rotate around the middle wings. As will be described later, with respect to the fittings 213a and 213b that are the base fittings of the middle wings, they are assembled in such a way that the fittings 211 and 218 are sandwiched in the middle from both sides, and thus do not have a rotating mechanism. Of course, the present invention is not intended to be limited, and it can also be configured such that the middle wings rotate in the same manner as the upper wings and the lower wings.

[0037] As Figure 3 shown in (b), in a state where a part of the fitting 218 of the shoulder joint is inserted into the fitting 211 that is the base fitting of the upper wing, the fittings 212a and 212b that are the base fittings of the lower wing are rotatably connected from both side surfaces. Moreover, the fittings 213a and 213b that are the base fittings of the middle wing are assembled with respect to these fitting groups. In addition, the fitting 211 corresponds to the first fitting, the fittings 212a and 212b correspond to the second fittings, and the fittings 213a and 213b correspond to the third fittings.

[0038] <Rotation action of the armor>

[0039] Refer to Figure 4 to explain the rotation action in the decoration part of the model toy of the present embodiment. Figure 4 (a) is a perspective view showing the rotation mechanism of the upper wing and the lower wing. Figure 4 (b) to Figure 4 (d) are side views showing the action sequence of the rotation mechanism of the upper wing and the lower wing. In Figure 4 , in order to explain the rotation action of the decoration part, only the fittings 211, 212a, and 212b related to the rotation mechanism in the decoration part are shown, and other fittings are omitted from the illustration.

[0040] Figure 4 (a) and Figure 4 (b) show the state before rotating the fittings 211, 212a, and 212b. Figure 4 (c) shows the case where the fitting 211 rotates in the arrow direction (prescribed direction) from the state of Figure 4 (b). Here, the fitting 211 can rotate to a certain extent relative to the fitting 212b as shown by the dotted line, but its rotation range is limited by the restricting part formed on the fitting 212b that restricts the rotation of the fitting 211. More specifically, by applying a force with the first force, the fitting 211 rotates to the position shown in Figure 4 (c) and is restricted from rotating by the above-mentioned restricting part.

[0041] Figure 4The (d) shows a case where a second force greater than the first force described above is further applied to the fitting 211. When a force is applied to the fitting 211 in the arrow direction with the second force, the fitting 212b rotates in a direction opposite to the rotation direction of the fitting 211 as shown by the one-dot chain line. Thereby, the restricting portion that restricts the rotation of the fitting 211 is released, and the fitting 211 can further rotate in the arrow direction as shown by the one-dot chain line.

[0042] In this way, since the rotating mechanism with armor is constituted, by lifting the fitting 211 in the arrow direction (upward direction), the fitting 211 is lifted to Figure 4 the position of (c), and by further applying a force, using the function of the restricting portion, as Figure 4 shown in (d), the fittings 212a and 212b rotate downward, and the fitting 211 further rotates. On the other hand, it is also possible to lift the fitting 211 in conjunction by lowering the fittings 212a and 212b downward and using the function of the restricting portion. Therefore, according to the present embodiment, by rotating one fitting, it is possible to rotate other fittings in conjunction. For example, it is possible to easily deploy the armor wings. Thereby, the effort of operating relatively small fittings in the model toy can be reduced.

[0043] <Structure of the restricting portion>

[0044] Refer to Figure 5 to explain the structure that restricts the rotation of the restricting and decorating portion of the model toy of the present embodiment. Figure 5 The (a) shows an exploded perspective view of the fitting 211 and the fitting 212a. Figure 5 The (b) shows a cross-sectional view of the fitting 211 and the fitting 212a and an enlarged view of the restricting portion 503. The fitting 212b has a structure symmetric to the fitting 212a in a prescribed orientation, so the description thereof is omitted.

[0045] The fitting 211 includes rod portions 511a and 511b and cylindrical connecting portions 512a and 512b formed at the lower ends of the rod portions 511a and 511b. In the fitting 212a, an annular connecting portion 501 having an opening 502 is provided. The connecting portion 512a of the fitting 211 is rotatably inserted into the opening 502 of the connecting portion 501. In addition, a restricting portion 503 for restricting the rotation of the fitting 211 and the fitting 212a is formed in the ring portion of the connecting portion 501.

[0046] Figure 5 The (b) shows a cross-section of the fitting 211 and the fitting 212a and an enlarged view of the restricting portion 503. As Figure 5As shown in (b), in fitting 212a, a restricting portion (wall surface) 503 is formed locally on the surface on the side where the connecting portion 512a is to be inserted, and the restricting portion 503 is formed along the shape of a part of the rod portion 511a of fitting 211. More specifically, the restricting portion 503 includes an arc portion 521 based on the shape of the arc portion 522 near the tip of the rod portion 511a, and also includes a straight portion extending upward in the drawing from the arc portion 521. By forming the restricting portion 503 in such a shape, it can function as follows: fitting 211 can rotate within a specified range, when the specified range is exceeded, the rotation is restricted, and when further force is applied, fitting 212a rotates in the opposite direction and fitting 211 rotates again.

[0047] The control of the rotation of these fittings 211 and 212 can be adjusted by the shape of the restricting portion 503. More specifically, by making the curvature of the arc portion 522 of the restricting portion 503 different from the curvature of the arc portion of the rod portion 511a, or by changing the inclination of the straight portion of the restricting portion 503, their rotation can be adjusted. For example, by making the curvature of the arc portion 521 greater than the curvature of the arc portion 522 of the rod portion 511a, the rotation of fitting 211 can be restricted at a position where it has rotated to a certain extent.

[0048] In addition, by adjusting the shapes (curvature, slope) of the arc portion 521 and the straight portion extending from the arc portion 521, the rotation direction of fitting 212a can also be changed according to the rotation of fitting 211. For example, in the present embodiment, fitting 211 is rotated, and when further force is applied in the case where the restriction of the restricting portion 503 is generated, the contact between fitting 211 and fitting 212a at the restricting portion 503 is released and they rotate in opposite directions. On the other hand, for example, by increasing the inclination of the above-mentioned straight portion (tilting toward the rod portion 511 side), it can be adjusted so that the contact between fitting 211 and fitting 212a at the restricting portion 503 is not released. In this case, if further force is applied as described above, fitting 212a can also rotate in the same direction following fitting 211. Thus, by adjusting the shape of the restricting portion 503, the rotation range and rotation direction of the associated fittings can be adjusted.

[0049] <Rotation restriction>

[0050] Refer to Figure 6 Describe the rotation restriction of the restricting portion 503 of the model toy of the present embodiment. Figure 6 (a) shows a cross-sectional view of fitting 211 and fitting 212a. Figure 6 (b) to Figure 6 (d) are enlarged views showing the rotation of fittings 211 and 212a near the restricting portion 503.

[0051] Figure 6The (b) of [the figure] shows a situation where the fitting 211 is rotated within a specified range in a specified direction. Here, as indicated by reference numeral 601, a part of the rod portion 511a abuts against the restricting portion 503. Accordingly, further rotation is restricted. The portion where the two fittings abut, as indicated by reference numeral 601, corresponds to, for example, the straight portion of the restricting portion 503. Further, this position varies according to the shape of the restricting portion 503.

[0052] Figure 6 The (c) of [the figure] shows Figure 6 a situation where a force is further applied to rotate the fitting 211 from the state of (b) of [the figure]. In this case, at the abutting portion indicated by reference numeral 601, a force is transmitted from the fitting 211 to the fitting 212a in the arrow direction, the abutment at reference numeral 601 is released, and the fitting 212a rotates in the direction opposite to the rotation direction of the fitting 211. Thereby, as indicated by reference numeral 602, a space for the movement of the rod portion 511a is ensured.

[0053] Figure 6 The (d) of [the figure] shows a situation where the restriction of the restricting portion 503 is released. By further applying a force, the restriction of the restricting portion 503 is released, and the fitting 212a rotates in the direction opposite to the rotation direction of the fitting 211. Thereby, Figure 6 the space of reference numeral 602 shown in (c) of [the figure] is ensured, and the fitting 211 can further rotate in the arrow direction using this space.

[0054] As described above, the model toy of the present embodiment includes a first fitting and a second fitting rotatably connected to the first fitting, and the second fitting includes a restricting portion that restricts the movement of a part of the first fitting when the first fitting rotates relative to the second fitting in a specified direction. Thus, according to the present embodiment, a novel configuration of a movable mechanism in a model toy, for example, can be provided.

[0055] The present invention is not limited to the above-described embodiment, and various modifications and changes can be made 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 a human, an animal, a robot, an insect, and a dinosaur.
