Description

The present invention relates to model toys and movable structures.

Doll toys (model toys) include various joints and movable parts in order to realize movements and poses similar to those of humans and animals. These mechanisms allow various poses to be achieved. However, providing a toy doll with the same number of joints as a human being requires a large number of members, and even a sophisticated doll toy has a limited number of parts, making it difficult to realize. Therefore, in order to realize the above-mentioned movements and poses, it is important to expand the range of motion of the joints and the parts connected to them while using fewer joints and members. By expanding the range of motion, you can perform movements with a higher degree of freedom and a variety of poses. Patent Document 1 proposes a quadrupedal animal doll that has a joint structure that allows realistic movements similar to those of real animals.

In addition, the same reference numbers are used for the same or similar configurations, and duplicate descriptions will be 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 toy model (doll body) 100 includes 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 restricted area caused by the relationship with other members. A head portion 101, which is a first portion, is connected to an upper body portion 102, which is a second portion, by a spherical connecting member (hereinafter also referred to as a ball joint). An arm portion 103 including a right arm portion 103a and a left arm portion 103b is further connected to the upper body portion 102 by a spherical connecting member. Leg sections including a right leg section 104a and a left leg section 104b are connected to the lower part of the upper body section 102.

Below, a neck joint structure that connects the head 101 and the upper body 102 will be described as a movable structure (movable structure) according to this embodiment. However, this is not intended to limit the present invention, and the movable structure described below can be applied not only to the neck joint, but also to other joints, such as shoulder joints, waist joints, and hip joints.

<Composition of the head>
Next, with reference to FIG. 2, the detailed configuration of the head 101 including the neck joint of the toy model 100 according to this embodiment will be described. FIG. 2(a) shows a side view of the model toy 100. FIG. 2(b) shows an exploded perspective view of a plurality of parts that constitute the head 101. Since FIG. 2(a) is a diagram similar to FIG. 1(b), explanation thereof will be omitted.

As shown in FIG. 2(b), the head 101 is composed of parts 201 to 208, and is rotatably connected to the upper body 102. Parts 201 and 202 constitute a connecting part that becomes the base of the neck joint. Part 201 is formed in a curved arcuate shape. Details of the shape will be described later.

Further, according to the present embodiment, the connecting part serving as the base of the neck joint is composed of at least two parts 201 and 202. However, this invention is not intended to be limited and may be constructed from one part. In the present invention, the spherical connecting portion of part 201 is inserted into the ring-shaped portion of part 203, and then connected to part 204. Furthermore, parts 205 are connected to these parts groups.

Part 206 is a facial part of the model toy 100, and is attached to part 205. Parts 207, 208a, and 208b are hair parts of the model toy 100, and are each attached so as to cover the above-mentioned parts.

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

As shown in FIG. 3(a), parts 201 and 202 constitute a connecting part that becomes the base of the neck joint. The part 201 includes a curved arcuate portion 311, a connecting portion 312 formed at one end of the curved portion 311, and a cylindrical recess 313 formed at the other end. The part 202 includes a rod portion 321, a connecting portion 322 formed at one end of the rod portion 321, and a connecting portion 323 formed at the other end. The part 203 also includes a cylindrical recess 331 and insertion parts 332a and 332b formed at both ends of the outer periphery of the recess 331, respectively.

The connecting portion 312 of the part 201 is formed in a spherical shape, and is rotatably connected to a cylindrical recess 331 formed in the part 203. Furthermore, the cylindrical connecting portion 322 of the part 202 is rotatably inserted into the recess (connecting portion) 313 formed in the other end of the part 201. Therefore, the parts 201 and 202 are connected to each other rotatably in the front-to-rear direction of the model toy 100. Furthermore, the connecting portion 323 of the part 202 is formed in a spherical shape, and is rotatably connected to a part of the upper body 102.

In this manner, in this embodiment, an example is described in which the connecting part that serves as the base of the neck joint is formed by rotatably connecting two parts. However, this is not intended to limit the present invention, and the connecting part may be formed of a single curved, arched part. Also, in the case of forming it from two parts, an example is described in which only part 201 is formed in a curved, arched shape, but part 202 may also be formed in a curved, arched shape.

Further, according to the present embodiment, the connecting portion 312 connected to the head 101 and the connecting portion 323 connected to the upper body portion 102 are each formed in a spherical shape. Therefore, each connecting part 312, 323 can be rotated in the other direction within the limit of interference with other parts.

Figure 3(b) shows parts 201, 202, and 203 connected together. Part 204 is formed with recesses 341a and 341b corresponding to insertion parts 332a and 332b of part 203. Insertion parts 332a and 332b are inserted from above recesses 341a and 341b, respectively, but this is not intended to limit the invention, and they may be configured to be inserted from other directions. Part 204 is a part for attaching a neck joint to other parts of head 101 using connecting parts.

Figure 3(c) shows the state where the insertion parts 332a and 332b of the part group consisting of parts 201, 202, and 203 are fitted into the recesses 341a and 341b of part 204. In this state, of the parts 201 and 202 that make up the connected parts, the connected parts can rotate around the connecting part 312 of part 201 as an axis.

<Operation of connected parts>
Next, with reference to FIG. 4, the operation of the connecting parts forming part of the neck joint according to this embodiment will be described. FIG. 4(a) shows the connecting parts in a normal state, and FIGS. 4(b) and 4(c) show the connecting parts in an operating state. Here, for ease of explanation, only parts 201 and 202 will be used. However, the parts 201 and 202 constituting the connected parts are connected to other parts as explained using FIG. 3.

Figure 4(a) shows the state before the connecting parts are operated. From this state, as shown in Figure 4(b), the connecting part 312 can be rotated in the direction of the arrow. This rotational movement is performed at the connecting part with part 203. Furthermore, from the state of Figure 4(b), the connecting part between parts 201 and 202 can be rotated in the direction of the arrow as shown in Figure 4(c).

According to this embodiment, the rotational movement region of the parts 201 and 202 shown in FIG. 4(c) can be expanded by the rotational movement in the connecting portion 312 shown in FIG. 4(b). For example, when the rotational movement shown in FIG. 4(c) is performed from the state shown in FIG. This impedes rotational movement and reduces the rotational area. On the other hand, in the state shown in FIG. 4(b), the connecting part moves in the direction of being pulled out to the rear of the head 101, and the head 101 and the upper body part 102 are moved in the direction shown in FIG. It is possible to expand the area between the parts 201 and 202, thereby expanding the area of rotational movement of the parts 201 and 202.

<Neck joint movement>
Below, a side cross section of the head 101 and upper body 102 according to this embodiment will be described with reference to Figures 5 and 6. Figure 5 shows a side cross section before operation. Figures 6(a) and 6(b) show the head 101 and upper body 102 in a state where they have been operated by a neck joint.

FIG. 5 shows the normal state before operating the neck joint. In this state, the connected part made up of parts 201 and 202 is curved from the shape of part 201 and arranged in an arcuate state. It can be seen that a predetermined empty area exists behind the curved portion 311 of the part 201 up to the part of the back of the head. A predetermined free area is indicated by a dotted line area 501. This area is an area for rotating the connecting parts, and is an area for pulling out the connecting parts from the head 101.

Figure 6 (a) shows the state when part 201 is rotated around connecting part 312 from the normal state in Figure 5. When part 201 is rotated around connecting part 312, it rotates in the direction of the arrow, and part 202 and upper body part 102 connected to part 202 rotate accordingly. For ease of explanation, a state in which the other parts are rotated while head 101 is fixed will be explained here. Naturally, it is also possible to fix upper body part 102 and rotate head 101 backwards in accordance with the rotation of the connecting parts.

In addition, in the rotation operation of FIG. 6(a), the part 201 rotates into a predetermined empty space (501) formed at the rear of the part 201. At that time, the connecting part is pulled out of the head 101 and moves to the rear side of the head 101. In other words, a part of the rear part of the head 101 enters the curved part of the part 201, which is the connecting part.

In the state of FIG. 6(a), the area between the back of the head and the shoulders, that is, the region on the back side of the neck, is enlarged compared to the state of FIG. 5. FIG. 6(b) shows how the part 202 in the connected parts is rotated in the direction of the arrow with respect to the part 201 using the enlarged area. The rotational movement can be performed until the upper part of the upper body part 102 comes into contact with a part of the back of the head 101. By operating in this manner, the toy model 100 according to the present embodiment can expand the range of motion of the neck joint and rotate the head 101 more rearward. In other words, according to the present embodiment, the range of motion of the head 101 facing upward can be expanded.

As explained above, the model toy according to the present embodiment includes a first part, a second part, and a connecting part that connects the first part and the second part. The connecting part is curved and formed into an arcuate shape, and is pulled out from the first part by rotating around the connecting part with the first part, and increases the rotation area of the second part more than before being pulled out from the first part. Expand. As described above, according to the present embodiment, it is possible to realize a joint structure that is movable so as to secure a space for expanding the range of motion in a model toy.

The connecting parts may also include a first part that is rotatably connected to the first portion, and a second part that is rotatably connected to the first part at one end and to the second portion at the other end. In this way, by configuring the connecting parts that form the base of the neck joint with two parts and allowing them to rotate relative to each other, the range of motion of the neck joint can be further expanded.

<Modification>
The present invention is not limited to the above-mentioned embodiment, and various modifications and changes are possible within the scope of the gist of the invention. In the above-mentioned embodiment, the movable structure is applied to the neck joint, but the present invention is not limited to this, and the movable structure may be used in other parts. For example, the movable structure may be used in joints such as the hip joint and shoulder joint that connect the legs.

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.
