Description

Human body and joint structure

Technical Field

The present invention relates to human body and joint configurations.

Background

In order to achieve an action and a posture close to a human or an animal, a human-shaped toy (human figure) includes various joints and movable parts. However, in the case where the human-shaped toy is provided with the same number of joints as that of human beings or the like, many members are required, and even if the human-shaped toy is compact, the number of joints or the like is limited, and it is difficult to achieve the above arrangement. Therefore, in order to realize such motions and postures, it is important to have a smaller number of joints and members, and to enlarge the movable region of the joints and the parts connected to the joints, thereby realizing natural motions. Patent document 1 proposes a human body in which a coupling member coupled to a hip joint rotates between an open position and a closed position, and a leg portion is coupled to a distal end of the coupling member. For the human body, the actions of leg opening and leg closing can be realized.

Disclosure of Invention

Problems to be solved by the invention

Although the linking member is capable of rotating between the open position and the closed position, its direction of motion is unidirectional. In order to realize natural movement like the limbs of a human being, it is desirable to be able to rotate in all directions. On the other hand, by providing a hip joint inside the waist as in the case of humans, a natural leg connected to the hip joint can be realized, but the movement space is limited. That is, the leg portions are required to be rotated more freely in a space restricted by the relationship with other members such as the waist portion and the skirt. For example, even if a spherical coupling portion is applied to a hip joint and a leg portion is rotatably connected, the movable region of the coupling member itself is limited by the waist portion of the human body, and it is difficult to achieve a realistic motion like a human, such as lifting the leg portion up to approximately 180 degrees.

The invention provides a structure for realizing more colorful postures on human bodies.

Means for solving the problems

The invention is, for example, a humanoid form, characterized in that it comprises: a 1 st coupling member having a spherical coupling portion at one end; a 1 st component that forms a recess into which the spherical coupling portion is rotatably fitted; and a 2 nd component rotatably connected to the other end of the 1 st coupling member.

Furthermore, the present invention is, for example, a figure, characterized in that the figure comprises: a 1 st connecting member having a spherical connecting portion at one end and a grip portion at the other end; a 1 st component that forms a recess into which the spherical coupling portion is rotatably fitted; and a 2 nd component rotatably connected to the grip portion of the 1 st coupling member.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, a more colorful posture can be realized in a human body.

Detailed Description

Hereinafter, embodiments will be described in detail with reference to the drawings. The following embodiments do not limit the invention claimed in the claims, and a combination of features described in all the embodiments is not essential to the invention. Two or more of the plurality of features described in the embodiments may be combined as desired. Note that the same or similar components are denoted by the same reference numerals, and redundant description thereof is omitted.

Appearance of human body

First, an example of the external appearance structure of the human body 100 of the present embodiment will be described with reference to fig. 1. Fig. 1 shows the front of the human form 100. Note that arrows on the top, bottom, left, right, and front and back show the orientation of the human body in the drawings, and the same applies to other drawings.

The human figure (also called human-shaped toy, model) 100 includes: a head 101, a chest 102, arm portions 103a, 103b, an abdomen 104, a waist portion (waist part) 105, and leg portions (leg parts) 107a, 107 b. The figure 100 is a movable figure such as a movable character model, and each component is movable within a limited range of a limited area due to a relationship with another member. The head 101 is coupled to the chest 102. An arm 103 (hereinafter also referred to as a ball joint) including a right arm 103a and a left arm 103b is further connected to the chest 102 by a spherical connecting portion, and is connected to the abdomen 104 at the lower portion. The abdomen 104 is connected to the waist (1 st member) 105. The leg 107 including the right leg 107a and the left leg 107b is coupled to the waist 105 by a spherical coupling portion. Reference numeral 106 denotes a lower body (lower body portion) including a waist portion 105 and leg portions 107 of the human figure 100. Hereinafter, a hip joint, which is a joint between the waist portion 105 and the leg portion 107 of the lower body 106, and a knee joint of the leg portion 107 will be described in detail.

< Structure of lower body >

Next, the configuration of the waist 105 and the leg 107 of the lower body 106 of the human figure 100 according to the present embodiment will be described with reference to fig. 2. Fig. 2 (a) is a front view showing a part of the lower body 106. Fig. 2 (b) is a side view showing a part of the lower body 106. Since the

leg portions

107a and 107b have the same configuration as the connection configuration to the waist portion 105, the left and right letters a and b will be omitted from the following description.

The leg 107 includes a thigh portion (part 2) 202 and a lower leg portion (part 3) 203, and is connected to the waist portion 105 by a spherical connecting portion 201 (ball-end connection). That is, the hip joint of the present embodiment is a member that movably connects the leg 107 to the waist 105 by a ball joint. Thus, the leg 107 can be rotated in all directions with respect to the waist 105 in a range that is subject to interference from other members, and various operations can be realized. As shown in fig. 2, the

connection portions

201a and 201b are connected to the respective concave portions of the waist portion 105 with almost no gap therebetween. By eliminating the gap in the joint portion in this manner, it is possible to suppress the uncomfortable feeling due to the gap, and reproduce a realistic joint like a human.

The thigh portion 202 and the lower leg portion 203 of the leg portion 107 are connected by a knee joint. The knee joint is provided with a ring-shaped rotation portion 204, and the lower leg portion 203 can rotate about a shaft member (rod member) inserted through a hole of the ring-shaped rotation portion 204. As shown in fig. 2 (a), the

rotation portions

204a and 204b of the left and

right leg portions

107a and 107b are assembled so that the center lines (broken lines) of the rotation portions have a predetermined inclination 205 with respect to the center line (one-dot chain line) connecting the thigh portion 202 and the lower leg portion 203. That is, the rotation portion 204 is not provided along the center line of the leg portion 107 or in parallel with the center line of the leg portion 107, but is formed in a state of being offset (twisted) with respect to the center line. Thus, the human body 100 can perform operations of M-leg sitting (japanese: meditation) (also referred to as "rale sitting" (japanese: female child seat り), paralyzed sitting (japanese: ペタン seat り), and duck sitting (japanese: あひる seat り)) from the sitting state to the sitting state in which the two

legs

107a and 107b are opened outward and the buttocks are placed on the ground. Details will be described later with reference to fig. 7.

< Assembly Structure of lower body >

Next, the detailed structure of the lower body of the human figure 100 according to the present embodiment will be described with reference to fig. 3 and 4. Fig. 3 is an exploded view showing a part of the lower body of the present embodiment. Fig. 4 shows a cross-sectional view of the lower body of the human figure 100 of the present embodiment. Here, a structure including the waist portion 105 and the left leg portion 107b as a part of the lower body of the human figure 100 will be described. Since the right leg portion 107a has the same configuration as the left leg portion 107b, the description thereof is omitted.

The waist portion 105 is configured to include

components

301 and 312. The component 301 is formed with a recess 311 for accommodating a coupling member (1 st coupling member) 302 coupled to each leg 107. The coupling member 302 is formed to include a coupling portion 201 and a grip portion 322. The coupling portion 201 is formed in a spherical shape, and is fitted into the recess 311 formed in the component 301 so as to be rotatable with respect to the recess 311. Thus, the connecting member 302 can rotate in all directions with respect to the waist 105 within a range that is subject to interference by other members. Therefore, the thigh 202 connected to the grip 322 of the coupling member 302 also moves in accordance with the rotation of the coupling member 302 in all directions.

The thigh portion 202 is constituted by

components

303, 304. The component 303 includes a rod member 331, and the rod member 331 is fitted to the grip portion 322 of the coupling member 302. The rod member 331 is fitted into the grip portion 322 and functions as a rotation shaft. The component 303 is connected to the component 304, and the component 304 is connected to the coupling member 305. Therefore, the thigh 202 is connected to the connecting member 302 so as to be rotatable about the rod member 331 as a rotation axis. The rotation direction is substantially the same as the vertical direction of the human body 100. The grip 322 is not limited as long as it is a structure that rotatably holds the rod member 331, and may be, for example, an annular holding portion.

The coupling member (2 nd coupling member) 305 is a component for coupling the thigh section 202 and the lower leg section 203 to realize a knee joint, and includes a ring-shaped rotation section 204. As described above, the rotating portion 204 is formed in a ring shape, the shaft member inserted into the hole functions as a rotating shaft, and the coupling member 305 itself rotates so as to bend the rotating portion 204 as a center. Therefore, the component 304 of the thigh portion 202 and the component 306 of the lower leg portion 203 connected to the connecting member 305 perform bending operations, and the knee joint operation is realized.

< movement of hip Joint >

Hereinafter, the operation of the hip joint of the human body 100 according to the present embodiment will be described with reference to fig. 5. Fig. 5 (a) and 5 (b) show side sectional views of the waist portion 105 and the thigh portion 202 of the human-shaped body 100.

As shown in fig. 5 (a), the coupling member 302 coupled to the component 301 of the waist portion 105 is rotatable in the direction of an arrow 501 by the spherical coupling portion 201. As the coupling member 302 rotates, the thigh portion coupled to the coupling member 302, i.e., the component 304, also rotates as indicated by the broken-line arrow. Further, since the coupling portion 201 has a spherical shape, the coupling member 302 and the component coupled to the coupling member 302 are not limited to being rotatable in the direction of the arrow 501, but can be rotatable in all directions within a range restricted by other members. This makes it possible to perform various operations such as an operation of twisting the thigh portion 202 inward (inward splaying (japanese: inner thigh)) or an operation of opening outward (outward splaying (japanese: outer thigh)).

Fig. 5 (b) shows a state in which the component 304 is further rotated from the state in fig. 5 (a). As described above, component 304 is connected to component 303, and rod member 331 of component 303 is rotatably fitted to grip portion 322 of coupling member 302. Thus, the

parts

303, 304 can be rotated in the direction of the arrow 502 with the rod member 331 as a rotation axis. This rotation operation can further rotate the component 304 from the state shown in fig. 5 (a) as indicated by a broken-line arrow. Therefore, by two-stage operation of the turning operation by the spherical connecting portion 201 and the turning operation by the rod member 331, as shown in fig. 5 (b), the thigh portion 202 of the human body 100 can be turned to a position (approximately 180 degrees) close to the upper body portion such as the waist portion 105 and the abdomen portion 104 of the human body 100, and a larger movable region can be provided. By realizing such a large movable region, various postures can be set.

In order to secure the above-described movable region, it is desirable that the coupling member 302 is formed to have a predetermined length for securing the movable region between the coupling portion 201 formed at one end thereof and the grip portion 322 formed at the other end thereof. That is, by having the above-described predetermined length, the range in which the element 304 is subjected to interference by another member such as the element 301 in accordance with the rotation of the thigh portion 202 can be reduced, and the movable region can be further expanded. As shown in fig. 5 (b), the grip portion 322 of the component 302 is formed to have a curved surface, and even when the thigh portion 202 is rotated, the curved surface is exposed to the outside and a gap is not formed between the grip portion 322 and the component 304. Thereby, the following structure is realized: even when the thigh 202 is rotated as shown in fig. 5 (b), no gap is generated on the back side of the thigh 202, and an unnatural impression is not given.

< action of knee joint >

Next, the operation of the knee joint of the human body 100 according to the present embodiment will be described with reference to fig. 6. Fig. 6 (a) and 6 (b) show side sectional views of the leg portion including the thigh portion 202 and the calf portion 203 of the human-shaped body 100.

Fig. 6 (a) shows a state where the leg portion 107 is extended. Fig. 6 (b) shows a state in which the lower leg portion 203 is rotated from the state in fig. 6 (a) around the rotation portion 204 of the connection member 305 that connects the thigh portion 202 and the lower leg portion 203. As shown in fig. 6 (b), the leg 107 can be bent by substantially 180 degrees by the rotation of the rotating portion 204. In order to realize such bending motion of the leg 107, it is necessary to suppress interference between the member 304 and the member 306 as much as possible. Therefore, according to the present embodiment, as shown by a broken line 601 in fig. 6 (a), the part of the component 306 that is brought into contact with the component 304 by the rotation of the rotating portion 204 is cut so as to match the shape of the component 304. By forming in this way, at the position indicated by the broken line frame 602 in fig. 6 (b), the component 304 and the component 306 are in close contact with each other, and a situation in which a part of the component 306 collides with the component 304 during rotation and the movable region is narrowed is avoided.

< gesture >

Next, an example of a posture that can be realized by the human body 100 of the present embodiment will be described with reference to fig. 7. Fig. 7 (a) shows a side sectional view of the waist portion 105 and the leg portions 107, and fig. 7 (b) shows a front view of the waist portion 105 and the leg portions 107.

Fig. 7 (a) shows a state in which the thigh 202 is rotated so as to approach the waist 105 and the abdomen 104 of the human body 100 in a state in which the leg 107 is bent around the rotating portion 204. When such an operation is performed with both legs, a knee-holding sitting (japanese: triangle り) (a leg-holding sitting (japanese: sport seat り)) or the like can be performed.

Fig. 7 (b) shows a state in which the leg portion 107 is bent around the rotation portion 204 and the lower leg portion 203 is opened outward at this time. As described with reference to fig. 2, this is because the rotation portion 204 that realizes the bending operation of the leg portion 107 according to the present embodiment is formed in a state of being offset (twisted) with a predetermined inclination 205 with respect to the center line of the

components

304 and 306. Thus, when the

leg portions

107a and 107b are bent, the

lower leg portions

203a and 203b are opened outward. Therefore, as shown in fig. 7 (b), the human body 100 can perform an M-legged sitting motion (also referred to as a rally, paralyzed, or duck sitting) in which the

lower leg portions

203a and 203b are opened outward and the hip portion is placed on the ground.

As described above, the human body of the present embodiment includes: a 1 st connecting member (302) having a spherical connecting portion (201) at one end and a grip portion (322) at the other end; a 1 st component (105, 301) that forms a recess (311) into which a spherical coupling portion is rotatably fitted; and a 2 nd component (202, 304) which is rotatably connected to the grip portion of the 1 st coupling member. This enables a human body to have a more colorful posture.

The shape of the human figure (human-shaped toy, model) is not particularly limited, and includes various shapes such as a human, an animal, a robot, an insect, a dinosaur, and a virtual creature.
