Description

[0001] This application is a divisional application of an application with a filing date of December 12, 2024, an application number of 202411824641.9, and an invention name of “Model Toys and Movable Structures”. 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, humanoid toys (model toys) include various joints and movable parts. Various postures can be achieved using these mechanisms. However, setting the same number of joints as those of humans in humanoid toys requires a large number of components, and even for delicate humanoid toys, this number is limited and difficult to achieve. Therefore, in order to achieve the above-mentioned movements and postures, it is important to have fewer joints and components and to expand the movable areas of the joints and the parts connected thereto. By expanding the movable area, movements with a higher degree of freedom and colorful postures can be performed. In Patent Document 1, a quadruped doll with a joint structure that can perform movements as realistic as those of real animals is proposed.

[0022] The following embodiments are described in detail with reference to the accompanying drawings. In addition, the following embodiments are not intended to limit the invention protected by the claims, and all combinations of features described in the embodiments are not necessary for the invention. Two or more of the multiple features described in the embodiments may also be combined arbitrarily. In addition, the same or similar structures are marked with the same reference numerals, and repeated descriptions are omitted.

[0023] <Appearance of the left leg of the model toy>

[0024] First, refer to Figure 1, the left leg portion of the present embodiment assembled on the model toy will be described. Figure 1 (a) shows the front appearance of the left leg portion 100 of the model toy, Figure 1 (b) shows the outer appearance side of the left leg part 100 of the model toy. In addition, the arrows of x, y, and z respectively indicate the directions of the top, left, and front of the model toy, and the same applies to the other drawings.

[0025] The left leg 100 includes a thigh 101, a knee joint 102, a calf 103 and a foot 104. In the present embodiment, as an example of a model toy, a humanoid robot is used as an example for description, but the intention of the present invention is not limited, and the present invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and decorations. About the right leg, although not shown, it is formed in left-right symmetry with the left leg, and because it has the same structure, the description is omitted.

[0026] In addition, in this embodiment, the example of applying the present invention to the leg of the model toy is described, but the same structure can also be applied to the arm, neck, waist, etc. of the model toy. In particular, in the arm, the upper arm, elbow joint, forearm and hand of the arm can each be set to a structure corresponding to the thigh, knee joint, calf and foot of the leg.

[0027] The thigh 101 is connected to the knee joint 102 in a rotatable manner. The knee joint 102 is also connected to the calf 103 in a rotatable manner. In addition, the foot 104 is connected to the lower part of the calf 103 using a spherical connecting portion. The knee joint 102 of this embodiment connects the thigh 101 as the first part and the calf 103 as the second part in a rotatable manner in the vertical direction of the model toy as the first direction. Moreover, the knee joint 102 connects the thigh 101 and the calf 103 in a rotatable manner in the horizontal direction of the model toy as the second direction different from the first direction. The details of these rotating mechanisms will be described later.

[0028] <Structures around the knee joint>

[0029] Next, refer to Figure 2 , the structure around the knee joint of the left leg 100 of this embodiment is described. Figure 2 (a) shows a side view of the left leg 100 decomposed into three parts. Figure 2 (b) shows an exploded structure of a part of the left leg 100. Here, the structure of the left leg 100 will be described, but the structure of the right leg (not shown) is the same as that of the left leg, so the description thereof will be omitted.

[0030] Reference numeral 200 indicates the periphery of the knee joint of the left leg 100. Figure 2 As shown in (b), the knee joint peripheral part 200 is composed of accessories 201 to 211. Accessory 201 is a base accessory of the knee joint, and accessories 202a and 202b forming a part of the thigh are connected in a manner of clamping the accessory 201 from both sides. In addition, accessories 203a and 203b forming a part of the calf are connected in a manner of clamping the accessory 201 from both sides.

[0031] An accessory 211 forming a part of the thigh 101 is rotatably connected to the upper part of the accessories 202a and 202b. The accessory 211 is also connected to other accessories of the thigh 101. In addition, an accessory 210 is rotatably connected to the lower part of the accessories 203a and 203b to form an ankle. The foot 104 is also rotatably connected to the accessory 210. The accessories 206 to 209 are external accessories of the legs.

[0032] <Structure of each accessory>

[0033] Next, refer to Figure 3 , various components constituting the rotation mechanism in the knee joint of the left leg 100 of the present embodiment will be described. Figure 3 Shows an exploded perspective view of each accessory.

[0034] The accessory 201 as a base accessory is configured to include a rod-shaped rotating shaft 311, a ring-shaped connecting portion 312, and a protrusion 313 formed on the outer periphery of the rotating shaft 311. The protrusion 313 is fitted into a recess 331a formed in the accessory 203a. The recess 331a is formed to have a larger size than the protrusion 313 so as not to restrict the rotation of the accessory 201.

[0035] In addition, a recessed portion (not shown) is also formed in the accessory 203b, and when the accessory 201 is clamped by the accessories 203a and 203b, the protrusion 313 of the accessory 201 is rotatably inserted into the recessed portions of the accessories 203a and 203b. The accessory 201 rotates in the horizontal direction (second direction) of the model toy around the rotation axis 311.

[0036] The cylindrical connecting portion 321a of the fitting 202a is inserted into the connecting portion 312 of the fitting 201. The inserted connecting portion 321a passes through the annular connecting portion 312 and is connected to the fitting 202b on the opposite side. In this way, the fittings 202a and 202b are rotatably connected in a manner of sandwiching the fitting 201.

[0037] The fitting 202a has a cylindrical connection portion 322a similar to the connection portion 321a. The connection portion 322a is inserted into and penetrates the ring-shaped connection portion 341 provided on the fitting 211, and is connected to the fitting 202b on the opposite side. That is, in addition to clamping the fitting 201, the fittings 202a and 202b are also rotatably connected in a manner of clamping the fitting 211.

[0038] The rotating mechanism with the connecting parts 321a and 322a as the rotating axis can rotate the accessories 201 and 211 connected to the connecting parts 321a and 322a in the vertical direction (first direction) of the model toy. In other words, these rotating mechanisms realize the rotating movement of the leg at the knee joint in a two-stage rotating movement, which can expand the movable area.

[0039] In addition, as the accessory 201 rotates around the rotation axis 311, the accessories 202a, 202b, and 211 connected to the connecting portion 312 also rotate. Therefore, the knee joint of the present embodiment can realize rotational movements in two rotational directions, namely, a first direction (vertical direction) of the model toy and a second direction (horizontal direction) different from the first direction. The second direction is, for example, a direction that is approximately 90 degrees different from the first direction. Thus, for example, it is possible to express the "bending" of the legs, for example, it is possible to express a gimmicky "bending of the foot" in actions such as high kicks. For details, refer to the user manual later. Figure 5 Narrative.

[0040] In addition, the present invention is not limited to the above-mentioned rotation direction, and the rotation direction can be determined as an arbitrary direction according to the position where the rotation mechanism is adopted. In addition, according to this embodiment, in order to realize the action of "bending" and "twisting" in the model toy, the second direction is defined as a direction that is approximately 90 degrees different from the first direction, but the present invention does not limit their angles, and can be set to any angle according to the action to be realized.

[0041] <Rotation Action>

[0042] Next, refer to Figure 4 and Figure 5 , various rotational movements of the left leg portion 100 of the model toy according to this embodiment are described. Figure 4 (a) Figure 4 (b) shows the rotational movement of the leg in the first direction (vertical direction). Figure 4 (c) shows the rotational movement of the leg in the second direction (horizontal direction). Figure 5 The posture using multiple rotational movements of the left leg is described. Figure 4 (a)~

[0043] Figure 4In (c), the accessories 202 and 203 are respectively composed of two accessories, but for ease of explanation, only the accessories 202a and 203a on the right side are shown here.

[0044] like Figure 4 As shown in (a), the accessory 211 can rotate in the direction indicated by the arrow (first direction) around the rotation axis 401. The rotation axis 401 is formed by inserting the cylindrical connection portion 322a of the accessory 202a into the ring-shaped connection portion 341 of the accessory 211. According to this rotational action, the accessory group of the thigh part 101 connected to the accessory 201 can rotate in the vertical direction (up and down direction) of the model toy.

[0045] like Figure 4 As shown in (b), the accessory 202a can rotate in the direction indicated by the arrow (first direction) with the rotation axis 402 as the center. The rotation axis 402 is formed by inserting the cylindrical connecting portion 321a of the accessory 202a into the ring-shaped connecting portion 312 of the accessory 201. According to this rotational action, the accessory group of the thigh part 101 connected to the accessory 201 can rotate in the vertical direction (up and down direction) of the model toy. Figure 4 By rotating in the same direction as the rotational movement shown in (a), the movable area of ​​the knee joint of the model toy can be expanded. Figure 4 As shown in (b), the knee joint can rotate to a position where the leg is folded.

[0046] like Figure 4 As shown in (c), the accessory 201 can rotate in the direction indicated by the arrow (the second direction) around the rod-shaped rotation axis 311. This rotation can be performed within the range sandwiched by the accessories 203a and 203b. In addition, by this rotation, the accessory group of the thigh 101 connected to the accessory 201 also rotates in conjunction.

[0047] According to the rotational movement, the accessory 201 can rotate in the horizontal direction (left-right direction) of the model toy relative to the connected accessories 203a, 203b. In this way, in the model toy of this embodiment, the knee joint can move in two rotational directions, namely, the first direction and the second direction different from the first direction, so that a more natural posture and movement can be performed.

[0048] Figure 5 (a) shows the left leg 100 before the rotation movement. Figure 5 (b) shows that Figure 5The lower leg 103 and the foot 104 are rotated in the direction of the arrows with the rotation axis 311 as the center from the state (a). In this way, in addition to the leg extension and flexion movement as the usual rotation movement of the knee joint, the model toy of this embodiment can also perform rotational movement in a direction different from the extension and flexion movement. Thus, for example, when the model toy performs a high kick or the like, by performing Figure 5 The twisting movement shown in (b) can reproduce the bending of the foot, allowing for a more realistic posture.

[0049] As described above, the model toy of this embodiment comprises: a base accessory having a first connecting portion, a second connecting portion, and a rotation axis; a first part connected to the base accessory by means of the first connecting portion in a manner that allows rotation in a first direction; and a second part connected to the base accessory by means of the second connecting portion, the second part being able to rotate in a second direction different from the first direction with the rotation axis of the base accessory as the center. Thus, according to this embodiment, a joint mechanism that can perform rotational movements in two directions can be realized in the joint structure provided in the model toy. Thus, in the legs, arms, etc., "bending" and "twisting" movements can be performed, and movements with a sense of gimmick can be performed. Thus, according to this embodiment, for example, a novel structure of a movable mechanism in a model toy can be provided.

[0050] The present invention is not limited to the above-mentioned embodiments, 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 humans, animals, robots, insects, and dinosaurs.
