Description

The present invention relates to model toys and movable structures.

To realize movements and poses similar to those of humans and animals, doll toys (model toys) include various joints and movable parts. These mechanisms allow for a variety of poses. However, providing a doll toy with the same number of joints as a human or other animal would require a large number of parts, and even in an elaborate doll toy, the number is limited and it is difficult to achieve this. Therefore, in order to realize the movements and poses described above, it is important to expand the range of motion of the joints and the parts connected to them while configuring them with fewer joints and parts. By expanding the range of motion, it is possible to perform movements with a higher degree of freedom and a variety of poses. Patent Document 1 proposes a quadruped animal doll with a joint structure that allows for realistic movements similar to those of real animals.

Two or more of the features described in the embodiments may be combined in any combination. In addition, the same reference numbers are used for the same or similar configurations, and duplicate descriptions are omitted.

<Appearance of the model toy>
A first embodiment of the present invention will be described below. 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. Fig. 1(b) shows the external side view of the model toy 100. Note that the arrows indicating up/down, left/right, and front/rear indicate the orientation of the model toy in the figure, and the same applies to the other figures.

The model toy (doll body) 100 comprises a head 101, an upper body 102, arms 103a, 103b, and legs 104a, 104b. The model toy 100 is a movable model toy such as a movable figure, and each part can be moved within a limited range caused by its relationship with other members. The head 101, which is the first part, is connected to the upper body 102, which is the second part, by a spherical connecting member (hereinafter, also referred to as a ball joint). The arms 103, including the right arm 103a and the left arm 103b, are further connected to the upper body 102 by a spherical connecting member. The legs, including the right leg 104a and the left leg 104b, are connected to the lower part of the upper body 102.

Below, the structure of an arm joint including an elbow joint and a wrist joint of an arm will be described as a movable structure (movable structure) according to this embodiment. However, there is no intention to limit the present invention, and the movable structure described below can be applied not only to an arm joint but also to other joints, such as leg joints including a knee joint and ankle joint, a neck joint, and a waist joint.

<Arm configuration>
Next, the detailed configuration of the arm 103a including the arm joint 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 model toy 100. Fig. 2(b) shows an exploded perspective view of a group of parts including a plurality of parts that make up the arm 103a. Fig. 2(a) is the same as Fig. 1(b), so its description will be omitted. The configuration of the arm 103b is the same as that of the arm 103a, so its description will be omitted.

As shown in FIG. 2(b), the arm 103a is made up of parts 201 to 213, and is rotatably connected to the upper body 102. Parts 201 to 203 form the movable axis that serves as the base of the elbow joint. Part 204 forms the shoulder joint, and parts 205 and 206 form the wrist joint.

Parts 201a and 201b are assembled so as to cover parts 201 and 204 from the outside. Part 204 is rotatably connected to parts 201a and 201b. Part 211 has a hollow portion inside, into which parts 201 and 202 that make up the elbow joint are inserted. Part 212 has a hollow portion inside, into which an insert portion formed at the bottom of part 202 is inserted. This insert portion is further inserted into part 203 that forms part of the movable shaft inside part 212. Furthermore, part 213 is connected to part 212 from the bottom side in the figure. A cylindrical recess is formed at the bottom of part 203, into which a wrist joint made up of parts 205 and 206 is inserted. Parts 207 and 208 are connected to the neck joint.

Parts 201 and 202 are rotatably connected to each other, forming a first movable axis of the elbow joint. Part 203 is rotatably connected to part 212, forming a second movable axis of the elbow joint. In this way, according to this embodiment, the elbow joint, which is one joint, is configured with two movable axes. This makes it possible to expand the range of motion. Furthermore, according to this embodiment, in order to expand the range of motion, parts 211 and 212 connected to the movable axes are connected so as to be movable in a predetermined direction, for example, in the vertical direction. This makes it possible to provide a further expanded range of motion by operating parts 211 and 212 so as to provide a gap between them and rotating them using the first and second movable axes. A detailed configuration will be described later.

<Detailed structure of the elbow joint>
Next, the detailed configuration of the elbow joint (arm joint) of the model toy 100 according to this embodiment will be described with reference to Fig. 3. Fig. 3(a) shows an exploded view of the parts that configure the first movable axis of the elbow joint. Fig. 3(b) and (c) show the assembled configuration of each part.

As shown in FIG. 3(a), part 201 has a cylindrical connecting portion 301. Part 202 has a ring-shaped connecting portion 302 that rotatably receives connecting portion 301, and a rod-shaped insertion portion 303. By connecting connecting portions 301 and 302, the first movable axis of the elbow joint can be formed.

As shown in FIG. 3(b), part 203 has a cylindrical recess 304 and a cylindrical connecting portion 305. Part 203 is connected to parts 201 and 202 by inserting insertion portion 303 into recess 304. Part 203 is rotatably connected to part 211 that constitutes part of arm 103a via connecting portion 305. This forms the second movable axis of the elbow joint.

Figure 3(c) shows a movable shaft connecting parts 201 to 203. In this movable shaft, connecting parts 301 and 305 function as a first movable shaft and a second movable shaft, respectively. Each movable shaft can rotate in the forward and backward directions of model toy 100.

<Movement of movable axis>
Next, the operation of the movable shaft (elbow joint) according to this embodiment will be described with reference to Fig. 4. Fig. 4(a) shows the movable shaft before operation, Fig. 4(b) shows the state in which the first movable shaft is operated, and Fig. 4(c) shows the state in which the second movable shaft is operated. In Fig. 4(a) to (c), parts 211, 212, and 213 that are assembled to cover the movable shaft are shown by dotted lines.

Figure 4(b) shows the state in which the first movable axis has been rotated from the movable axis before operation shown in Figure 4(a). The first rotation axis is achieved by rotating part 201 in the forward direction of model toy 100 relative to part 202. As shown in Figure 2(b), part 201 is covered with parts 210a and 210b, and part 204, which functions as a shoulder joint, is connected to the end of part 201. Therefore, the arm 103a can be bent by rotating around the first movable axis.

Figure 4(c) shows the state in which the second movable axis is rotated from the movable axis state shown in Figure 4(b). The second movable axis is rotated by rotating the connection part 305 of part 203, which is rotatably connected to part 212. Therefore, parts 201 and 202 connected to part 203 also rotate accordingly. Therefore, the arm part 103a can be further bent by rotating about the second movable axis.

<Arm movement configuration>
The movable configuration of the arm 103a according to this embodiment will be described below with reference to Figures 5 and 6. Figure 5(a) shows a rear view of the movable shaft, Figure 5(b) shows a bottom view of the part 212, and Figure 5(c) shows a bottom view showing the state in which the movable shaft is connected to the part 212. Figures 6(a) and 6(b) show side cross-sectional views of the arm 103a. Note that the configuration of the arm 103b is similar to that of the arm 103a, so a description thereof will be omitted.

As shown in FIG. 5(a), the movable shaft of the arm 103a according to this embodiment has cylindrical connecting parts 501, 502 and connecting parts 505, 506 formed on the first and second movable shafts, respectively, which protrude to the left and right. The connecting parts 501, 502 are connected to the part 212, and the connecting parts 505, 506 are connected to the part 211. The assembly configuration of the connecting parts 501, 502 to the part 212 will be described below.

As shown in FIG. 5(b), part 212 has cutouts 503 and 504 formed therein to receive connecting portions 501 and 502. Cutouts 503 and 504 are each formed to have the length indicated by the arrow. In other words, connecting portions 501 and 502 are connected so as to be movable in the vertical direction within the range indicated by the arrow. Note that the assembly configuration of connecting portions 505 and 506 to part 211 is similar, so a description thereof will be omitted. Cutouts 503 and 504 formed in part 212 correspond to the second cutout, and a cutout (not shown) formed in part 211 corresponds to the first cutout.

Figure 5 (c) shows parts 211 and 212 assembled to the movable shaft. As shown, connecting parts 501 and 502 are assembled to cutout parts 503 and 504, respectively, but it can be seen that there is extra space in cutout parts 503 and 504. In other words, connecting parts 501 and 502 are not fitted all the way into cutout parts 503 and 504, and there is space up to the innermost part. Therefore, by utilizing this space, parts 211 and 212 can move up and down relative to the movable shaft.

Figure 6(a) shows a first state in which parts 211 and 212 are in contact. Meanwhile, Figure 6(b) shows a transition to a second state in which parts 211 and 211 are separated by moving parts 211 and 212 in the direction of the arrow. In the second state, gaps are provided between parts 210 and 211, and between parts 211 and 212, which has the effect of expanding the range of motion of the first movable axis and the second movable axis.

In addition, the arm 103a according to this embodiment has an elbow joint having a first movable axis and a second movable axis, as well as a wrist joint formed by a third movable axis. The wrist joint is formed by connecting parts 205 and 206. Specifically, the wrist joint is formed by rotatably inserting the rod-shaped insertion part of part 206 into the cylindrical recess of part 205. The insertion part serves as the axis of rotation, and is formed to be a substantially horizontal axis of rotation in the front-to-rear direction of the model toy 100. This allows for a wider range of motion compared to when the insertion part is inserted obliquely at a predetermined angle rather than horizontally.

<Example of operation>
An example of the operation of the arm 103a according to this embodiment will be described with reference to Fig. 7. In Fig. 7, the arm 103a is shown shaded.

As shown in FIG. 7, in the model toy 100, the arm portion 103a can be bent significantly by moving the first and second movable axes. Furthermore, the hand portion can be bent by the third movable axis at the wrist joint. Therefore, as shown in the figure, the model toy 100 can perform a motion such as "resting one's chin on one's hand."

As described above, the model toy according to this embodiment comprises a parts group including a plurality of parts, and a movable shaft provided inside the parts group and connecting at least a portion of the plurality of parts. The movable shaft comprises a first movable shaft connected to a first part of the plurality of parts, and a second movable shaft connected to a second part of the plurality of parts. Thus, according to this embodiment, it is possible to provide a mechanism for realizing a new structure for expanding the range of motion in a model toy.

<Modification>
The present invention is not limited to the above embodiment, and various modifications and changes are possible within the scope of the gist of the invention. In the above embodiment, the movable structure is applied to an arm joint including an elbow joint, but the present invention is not limited to this embodiment and may be used in other parts. For example, the movable structure may be used in a leg joint including a knee joint, a shoulder joint, a waist joint, or other joints.

Although an example of a model toy has been described, the shape of the model toy (doll body) is not particularly limited and may include a variety of shapes such as humans, animals, robots, insects, dinosaurs, imaginary life forms, etc. Also, the shape of the model toy is not particularly limited as long as it includes movable parts.
