Description

[0001] This application is a divisional application of the invention patent application filed on March 9, 2021, with a priority date of March 23, 2020, application number 202110255844.0, entitled "Bending Structure of Humanoid Body and Humanoid Body Using the Same and Method for Manufacturing Humanoid Body". Technical Field

[0002] This invention relates to the curved structure of a humanoid figure, the humanoid figure using it, and a method for manufacturing a humanoid figure. Background Technology

[0003] Conventionally, humanoid figures, including those of humans, animals, and various characters, have structures in which skeletal members are embedded within a covering member representing the humanoid figure's shape. Among such humanoid figures, one type is known that, for example, allows the joints of the doll's arms and legs to bend and maintain that bent posture, thus assuming the same posture as a human (see, for example, Patent Document 1).

[0004] The humanoid body described in Patent Document 1 has the following structure: In the construction of a doll that imitates the skeleton with joints in the components of the arms or legs that constitute the human body, an intermediate joint portion that is not present in the human body is provided at a position different from the joint portion of the arms and legs of the human body. The intermediate joint portion is used to make the joint portion contact and separate and to make the joint portion stop and maintain at a predetermined angle.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2006-122250 Summary of the Invention

[0008] The problem the invention aims to solve

[0009] In Patent Document 1, a structure is used to maintain the bending posture of the joints of a human-shaped body by utilizing an intermediate joint that does not exist in the human body to maintain the bending angle of the joints. Therefore, since it differs from the actual structure of the human body, there is a problem that the bending method of the joints becomes unnatural.

[0010] Furthermore, in general, in humanoid figures with skeletal structures covered by covering members, when the bending angle of the joints is large (acute bending), there is a problem of wrinkles forming on the inside and around the curved parts, such as the joints. Additionally, on the outside of the curved parts, when the covering member is extended, there is a problem that the bending posture (bending angle) of the curved parts, such as the joints, becomes difficult to maintain due to the stretching of the covering member.

[0011] The purpose of this invention is to provide a curved structure for a human figure that can express more natural curves, as well as a human figure and a method for manufacturing the human figure that uses it.

[0012] Solution for solving the problem

[0013] The bending structure of the humanoid body of the present invention comprises a skeletal part having a bendable bending portion and a covering portion covering the skeletal part, wherein the skeletal part has a three-dimensional shape that roughly mimics the concave and convex shape of the outer surface of the humanoid body, the outer surface of the covering portion has the concave and convex shape of the outer surface and the inner surface of the covering portion has an inner surface concave and convex shape that contacts the outer surface of the skeletal part, and the covering portion is soft.

[0014] Alternatively, in the curved structure of the humanoid body of the present invention, the covering portion may be provided in a manner that allows it to be misaligned relative to the outer surface while in contact with the outer surface of the skeletal portion.

[0015] Alternatively, in the curved structure of the humanoid body of the present invention, the humanoid body may imitate the shape of a human body, and the skeletal part may include: two partial skeletal parts that imitate the shape of muscles as the concave-convex shape of the outer surface; and the curved part that connects the two partial skeletal parts in a flexible manner, and the covering part is provided to cover the thickness of the skeletal part in a substantially uniform manner.

[0016] Alternatively, in the curved structure of the humanoid body of the present invention, the covering portion may be formed such that the wall thickness of the portion covering the curved portion is thinner than the wall thickness of the other portion.

[0017] Alternatively, in the curved structure of the human body of the present invention, the curved portion may have multiple connecting members that connect two local skeletal portions, and the outer surface of the multiple connecting members may have a bone-shaped portion that imitates the shape of human bones.

[0018] Alternatively, in the curved structure of the human body of the present invention, the curved portion may be an elbow joint, the two partial skeletal portions may include an upper arm skeletal portion and a forearm skeletal portion, and the plurality of connecting members may include: a first connecting member connected to the upper arm skeletal portion; a second connecting member connected to the forearm skeletal portion; and a third connecting member that rotatably supports the first connecting member and the second connecting member and connects the first connecting member and the second connecting member, wherein the bone-shaped portion is provided in the third connecting member.

[0019] Furthermore, the humanoid body of the present invention is a humanoid body formed by having the curved structure of the humanoid body described above.

[0020] Furthermore, the method for manufacturing a humanoid figure according to the present invention includes a skeletal part having a bendable curved portion and a covering portion covering the skeletal part. The method for manufacturing a humanoid figure includes the following steps: setting the concave-convex shape of the outer surface of the humanoid figure as the inner wall shape of a mold space for molding; placing the skeletal part, which is scaled down to mimic the three-dimensional shape of the concave-convex shape of the outer surface, in the mold space; and injecting a soft covering resin constituting the covering portion into an injection space formed by making the three-dimensional shape of the skeletal part correspond to the concave-convex shape of the inner wall shape.

[0021] Alternatively, in the method for manufacturing the humanoid body of the present invention, the covering portion may be separated from the outer surface of the skeletal portion after the soft covering resin is injection molded.

[0022] The effects of the invention

[0023] According to the present invention, it is possible to provide a curved structure of a human figure that can express a more natural curvature and a human figure that uses it. Attached Figure Description

Detailed Implementation

[0040] Hereinafter, a humanoid body and its curved structure according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0041] Figure 1 This is the front view of humanoid figure 1.

[0042] like Figure 1 As shown, the humanoid figure 1 is a humanoid figure with left and right arms 4L, 4R and left and right legs 5L, 5R relative to the torso 2, and a head 3, which, for example, imitates the bulging muscles of a human body. As will be described later, the humanoid figure 1 has a skeletal part 11 covered by a covering part 18 (see reference). Figure 2 The structure of the humanoid figure 1 is such that the elbow joints 4e of the left and right arms 4L and 4R and the knee joints 8 of the left and right legs 5L and 5R are able to bend.

[0043] Figure 2 It is an enlarged representation Figure 1 An enlarged view of the left arm 4L of the humanoid figure 1 shown. Figure 3 This is an enlarged view of the skeletal part 11 of the left arm 4L.

[0044] like Figure 2 As shown, the left arm 4L has a skeletal part 11 inside that allows the elbow joint 4e to bend. In addition, the left arm 4L has a shoulder part 6 attached to its upper side and can be attached to the torso 2, and a hand part 7 attached to its lower side.

[0045] like Figure 3 As shown, the two partial bone parts of the bone part 11, namely the upper arm bone part 13 and the forearm bone part 14, are connected in a flexible manner by means of the bending part 20.

[0046] The following is for reference Figures 4-9 The three-dimensional shape (convex-concave shape) of the left arm portion 4L and the skeletal portion 11 is described. Furthermore, Figures 4-9 The three-dimensional shape of the left arm 4L and the skeleton 11 is represented by a side view of the three-dimensional shape of the left arm 4L and the skeleton 11 viewed from three directions relative to the human figure 1: left, inside (right), and rear.

[0047] Figure 4 (a) is a side view taken from the left when the left arm 4L is mounted on the torso 2. Figure 4 (b) is a side view of the skeletal part 11 of the left arm 4L when viewed from the left side. Figure 6 (a) is a side view of the left arm 4L being mounted on the torso 2, viewed from the inside (right) side. Figure 6 (b) is a side view of the skeletal part 11 of the left arm 4L when viewed from the inside. Figure 8 (a) is a side view from the rear, showing the left arm 4L mounted on the torso 2. Figure 8 (b) is a side view of the skeletal part 11 of the left arm 4L when viewed from the rear.

[0048] like Figure 4 of (a), Figure 6 (a) and Figure 8 As shown in (a), the outer surface 18us of the covering portion 18 of the left arm portion 4L has a concave-convex shape that mimics the shape of a muscle. More specifically, for example, in the upper arm portion 4u, a biceps brachii portion 4ua, a triceps brachii portion 4uc, etc., are formed in a suitably bulging manner, and in the forearm portion 4d, a forearm extensor muscle group 4da and a forearm flexor muscle group 4dc are formed. Furthermore, in the wrist portion, a brace portion 30 that mimics a wrist brace is formed in a manner that surrounds the wrist.

[0049] like Figure 4 (b) Figure 6 (b) and Figure 8 As shown in (b), the outer surface 11s of the skeletal portion 11 has a concave-convex shape that mimics the muscle shape of the outer surface 18us of the covering portion 18. Specifically, in the upper arm skeletal portion 13 corresponding to the upper arm portion 4u, a biceps-related protrusion 13a and a triceps-related protrusion 13c are formed; in the forearm skeletal portion 14 corresponding to the forearm portion 4d, an extensor muscle-related protrusion 14a corresponding to the forearm extensor muscle group 4da and a flexor muscle-related protrusion 14c corresponding to the forearm flexor muscle group 4dc are formed. Additionally, in the wrist portion, a brace-related protrusion 30a corresponding to the brace portion 30 is formed. Furthermore, in the curved portion 20 connecting the upper arm skeletal portion 13 and the forearm skeletal portion 14, a bone-shaped portion 23ws (described later) is provided and has a shape mimicking the elbow joint 4e.

[0050] Figure 5 This is a partial sectional side view showing the correspondence between the concave and convex shapes of the skeletal part 11 and the covering part 18 when viewed from the left side with the left arm part 4L installed on the torso 2. Figure 7 This is a partial sectional side view showing the correspondence between the concave and convex shapes of the skeletal part 11 and the covering part 18 when viewed from the inside with the left arm part 4L installed on the torso 2. Figure 9 This is a partial sectional side view showing the correspondence between the concave and convex shapes of the skeletal part 11 and the covering part 18 when viewed from the rear with the left arm part 4L installed on the torso 2.

[0051] like Figure 5 , Figure 7 as well as Figure 9 As shown, the cover 18 is provided in contact with the outer surface 11s of almost the entire area of ​​the bone portion 11. Furthermore, the wall thickness t1 of the cover 18 varies slightly depending on the location, but is provided with a substantially constant wall thickness. That is, the uneven shape of the outer surface 18us of the cover 18 corresponds to the muscle shapes of the outer surface 11s of the bone portion 11 and the uneven shape of the brace portion 30.

[0052] The skeleton part 11 is constructed from a synthetic resin or metal with a certain degree of rigidity. The covering part 18 mimics human skin and is made of a soft synthetic resin, synthetic rubber, or natural rubber. Furthermore, the covering part 18 is not bonded to the skeleton part 11 and is movable relative to it. Therefore, the covering part 18 can shift and move around the curved portion 20 as it expands and contracts, and can bend along with the curved portion 20 of the skeleton part 11.

[0053] For reference Figures 4-9 As explained, for the upper arm bone portion 13 and the forearm bone portion 14, the outer surface 11s has a bulge corresponding to the appearance shape of the muscles in the upper arm portion 4u and the forearm portion 4d, that is, a three-dimensional shape that roughly mimics the concave and convex shape of the outer surface of the human body 1 in a scaled-down manner. In addition, the appearance of the curved portion 20 also has a three-dimensional shape with concave and convex shapes that mimic the shape of the elbow bone. Therefore, when the curved portion 20 is bent, the bone portion 11 and the covering portion 18 can move relative to each other, and the relative movement can be appropriately restricted by the concave and convex shapes.

[0054] Figure 10 This is an exploded three-dimensional view of the skeletal part 11 of the left arm 4L. Figure 11 Observing from the opposite direction Figure 10 A perspective view of the curved portion 20 of the skeletal portion 11 shown.

[0055] like Figure 10 As shown, the left arm portion 4L is a structure in which the two local skeletal portions 13 of the upper arm and 14 of the forearm are connected by a curved portion 20 with multiple connecting members, which corresponds to the elbow joint 4e.

[0056] The curved portion 20 includes: a first connecting structural member 21 connected to the upper arm bone portion 13; a second connecting structural member 22 connected to the forearm bone portion 14; and a third connecting structural member 23 connected to the upper arm bone portion 13 and the forearm bone portion 14.

[0057] The first connecting structural member 21 includes: a pin 21p, which is inserted into and connected to a joint-side recess 13h at one end of the upper arm bone portion 13; and a flat, generally cylindrical rotating portion 21a, which extends from one end of the pin 21p and has a stepped portion 21d. More specifically, the rotating portion 21a has a stepped portion 21d that protrudes in a direction orthogonal to the axis of the pin 21p and extends offset from that axis. In addition, a cylindrical hole 21h is formed in the rotating portion 21a that opens in a direction orthogonal to the axis of the pin 21p.

[0058] The second connecting structural member 22 includes: a pin 22p, which is inserted into and connected to a joint-side recess 14h at one end of the forearm bone portion 14; and a flat, generally cylindrical rotating portion 22a extending from one end of the pin 22p. A cylindrical hole 22h is formed in the rotating portion 22a, opening in a direction orthogonal to the axis of the pin 22p.

[0059] like Figure 10 and Figure 11 As shown, the third connecting structure 23 includes: a pair of support shafts 23b, which are inserted into the cylindrical holes 21h of the first connecting structure 21 and the cylindrical holes 22h of the second connecting structure 22; a dividing wall 23w, which separates the pair of support shafts 23b; and a base plate 23a, which is provided with the dividing wall 23w and the two support shafts 23b.

[0060] Furthermore, the substrate 23a is formed in a generally circular shape such that the base of the pair of support shafts 23b corresponds to the shape of the rotating portions 21a and 22a of the first connecting structural member 21 and the second connecting structural member 22. Additionally, the dividing wall 23w is provided, for example, with a bone-shaped portion 23ws that protrudes slightly outward in a textured manner, mimicking the bone shape of a human elbow joint (see reference). Figure 11 ).

[0061] In the curved section 20 configured in this way, the cylindrical holes 21h and 22h are engaged with the pair of support shafts 23b in a manner that provides moderate frictional resistance and allows rotation. That is, it is configured to have a predetermined degree of firmness that allows the elbow joint 4e to bend and maintain that bent state. In particular, when the elbow joint 4e is bent significantly, the bone-shaped portion 23ws can be visualized in a manner that appears on the outer side of the elbow joint 4e.

[0062] Additionally, on the other end of the upper arm bone portion 13 (in Figure 10 The upper part (in the middle) has a shoulder-side connecting part 13b that connects to the shoulder part 6. Additionally, on the other end of the forearm bone part 14 (in... Figure 10 The lower part of the middle section is provided with a hand-side connecting part 14b that is connected to the hand part 7.

[0063] Figure 12 This is a sectional view of the main part of the elbow joint 4e covering the left arm 4L, which has been cut open.

[0064] Elbow joint 4e, for example Figure 12 As shown, the thin-walled portions 18c of the inner and outer sides of the elbow of the portion of the covered portion 18 covering the bent portion 20 are formed such that the wall thickness t2 of the inner side of the elbow and the wall thickness t3 of the outer side of the elbow are thinner than the wall thickness t1 of the other portions.

[0065] If the wall thickness of the covering portion 18 is constructed in a manner that locally thins out, then for example, Figure 12 As shown by the imaginary line (single-dotted line), when the elbow joint 4e is bent (bent in the direction of arrow R), the portion of wall thickness t2 on the inner side of the elbow, where the covering portions 18 do not interfere with each other, easily bends inward. Furthermore, because the wall thickness is relatively thin, not only is bending easy, but the formation of wrinkles is also suppressed. On the other hand, the portion of wall thickness t3 on the outer side of the elbow stretches slightly, but because the wall thickness is relatively thin, the tensile force is reduced.

[0066] The following is for reference Figure 13 and Figure 14 The manufacturing method of the humanoid body 1 will be explained using the left arm 4L as an example.

[0067] Figure 13 This is a cross-sectional view of the main part of the molding die, illustrating an example of a molding method for humanoid figure 1. Additionally, Figure 14 This is an exploded perspective view showing the assembly of the left arm 4L after the cover 18 has been formed.

[0068] The cover portion 18 is formed by injection molding using a molding die 50.

[0069] The forming mold 50 is composed of, for example, an upper mold 51 and a lower mold 52, which have the concave-convex shape of the outer surface of the left arm portion 4L of the humanoid body 1 on the inner wall surface 50ws of the mold space CS.

[0070] On the other hand, the skeleton part 11 is configured as a three-dimensional shape that mimics the uneven shape of the outer surface of the left arm part 4L in a scaled-down manner, as described above. Furthermore, the skeleton part 11 is positioned and fixed within the mold space CS. That is, the skeleton part 11 is positioned, for example, with the shoulder-side connecting part 13b and the hand-side connecting part 14b located on the parting line PL. Thus, the three-dimensional shape of the outer surface 11s of the skeleton part 11 corresponds to the uneven shape of the inner wall surface 50ws, thereby forming the injection space IS. The interval of this injection space IS becomes the wall thickness of the cover part 18.

[0071] A soft covering resin 18m constituting the covering portion 18 is injected from the injection gate 50 into the injection space IS formed in this way. As a result, a covering portion 18 is formed that closely adheres to the outer surface 11s of the skeletal portion 11 with a complex appearance shape and represents the shape of the outer surface 18us of the humanoid body 1.

[0072] In addition, the soft covering resin 18m is appropriately cooled and cured after injection molding to form the covering part 18. This covering part 18 is made of, for example, silicone rubber, and is in a state of being separate from the outer surface 11s of the bone part 11.

[0073] like Figure 14As shown, for the left arm 4L formed in this way, the shoulder-side connecting part 13b is inserted into and connected to the hole 6h of the shoulder 6, and the hand-side connecting part 14b is inserted into and connected to the hole 7h of the hand 7. The left arm 4L is then assembled by attaching the shoulder 6 to the torso 2. The right arm 4R is manufactured and assembled in the same manner. The two legs 5L and 5R can also be manufactured in the same way.

[0074] According to the bending structure of this embodiment, the skeletal part 11 has a three-dimensional shape that roughly mimics the concave and convex shape of the outer surface of the human body 1. The outer surface 18us of the covering part 18 has a concave and convex shape, and the inner surface 18is has a concave and convex shape that contacts the outer surface 11s of the skeletal part 11. Therefore, when the bending part 20 is bent, the concave and convex shapes improve the integrity of the skeletal part 11 and the covering part 18. In addition, it can prevent the covering part 18 and the bending part 20 from returning to their original shape due to the elasticity of the covering part 18. The covering part 18 becomes easier to follow the bending of the skeletal part 11 while maintaining the shape of the outer surface 18us. Furthermore, it can suppress wrinkles and stretching of the covering part 18 covering the bending part 20 and express the natural bending of the bending part 20.

[0075] Furthermore, in the curved structure of this embodiment, the covering portion 18 is provided in a manner that allows it to be misaligned relative to the outer surface 11s of the bone portion 11 while in contact with it. Therefore, when the curved portion 20 is bent, wrinkles and stretching caused by the misalignment of the covering portion 18 relative to the outer surface 11s of the bone portion 11 can be suppressed. As a result, the covering portion 18 becomes easier to follow the bending of the bone portion 11 while maintaining the shape of its outer surface 18us, and can exhibit a natural bending of the curved portion 20.

[0076] Furthermore, in the curved structure of this embodiment, the human body 1 mimics the shape of a human body, and the skeletal part 11 includes: two partial skeletal parts (upper arm skeletal part 13 and forearm skeletal part 14) that mimic the shape of muscles as the concave-convex shape of their outer surface; and a curved part 20 that connects the two partial skeletal parts in a flexible manner. By setting the covering part 18 to cover the thickness of the skeletal part 11 in a substantially uniform manner, the curved part 20, which corresponds to the joint, can be set to a shape that is slightly tapered in the middle compared to the bulging part of the muscle. As a result, wrinkles and stretching of the covering part 18 of the curved part 20 can be suppressed, and the curvature of the human body's joints can be naturally represented.

[0077] Furthermore, in the curved structure of this embodiment, the covering portion 18 is formed such that the wall thickness of the portion covering the curved portion 20 is thinner than that of the other portion, thus more effectively suppressing the generation of wrinkles and stretching of the covering portion 18 of the curved portion 20, and more naturally representing the curvature of the human joint.

[0078] Furthermore, in the bending structure of this embodiment, multiple connecting members are provided: a first connecting member 21, which is connected to the upper arm bone portion 13; a second connecting member 22, which is connected to the forearm bone portion 14; and a third connecting member 23, which rotatably supports the first connecting member 21 and the second connecting member 22, and connects the first connecting member 21 and the second connecting member 22. In addition, the third connecting member 23 has a bone-shaped portion 23ws that imitates the elbow joint 4e, so that when the elbow joint 4e is bent, the bending of the elbow can be naturally represented.

[0079] Furthermore, in the humanoid body 1, the skeletal portion 11 of the curved structure of the humanoid body 1 has a three-dimensional shape formed by reducing the concave and convex shape of the outer surface of the humanoid body 1, and the outer surface 18us of the covering portion 18 has an outer surface concave and convex shape and the inner surface 18is has an inner surface concave and convex shape that contacts the outer surface 11s of the skeletal portion 11. Therefore, when the curved portion 20 is bent, the covering portion 18 becomes easy to follow the bending of the skeletal portion 11 while maintaining the shape of the outer surface. As a result, a humanoid body 1 can be provided in which the bending of the curved portion 20 of the humanoid body 1 can be expressed naturally when the bending portion 20 of the humanoid body 1 is bent.

[0080] Furthermore, the manufacturing method of the humanoid body 1 in this embodiment includes the following steps: using the concave and convex shape of the outer surface of the humanoid body 1 as the inner wall shape of the mold space CS for molding, placing the skeleton part 11, which is a three-dimensional shape that imitates the concave and convex shape of the outer surface in a reduced size, in the mold space CS, and injecting a soft covering resin 18m constituting the covering part 18 into the injection space IS formed by making the three-dimensional shape of the skeleton part 11 correspond to the concave and convex shape of the inner wall shape. Therefore, even if the concave and convex shape of the outer surface of the humanoid body 1 is complex, the covering part 18 with the desired wall thickness corresponding to the skeleton part 11 can be easily provided.

[0081] Furthermore, in the manufacturing method of the humanoid body 1 in this embodiment, the soft covering resin 18m separates from the outer surface 11s of the bone portion 11 after injection molding. Therefore, when the curved portion 20 is bent, the covering portion 18 can be misaligned relative to the outer surface 11s of the bone portion 11. As a result, the covering portion 18 can easily follow the bending of the bone portion 11 while maintaining the shape of the outer surface 18us.

[0082] The above description describes one embodiment of the present invention, but the present invention can be appropriately modified within the scope of its technical concept. For example, in the above embodiment, a humanoid body 1 in the shape of a human body was described, but the humanoid body 1 of the present invention is not limited to the shape of a human body, and can also imitate animals or specific characters.

[0083] Furthermore, while the bending portion 20 in the above embodiment has been described for the elbow joint 4e, it can also be applied to, for example, the wrist, shoulder joint, knee joint, hip joint, ankle, etc. Additionally, it can be applied to parts that are bent to some extent, such as the spine and neck.

[0084] Furthermore, in the above embodiment, the case where the outer surface protrusion and concavity shape of the humanoid body 1 mainly imitates the shape of muscles has been described, but it is not limited to this. It may also be the outer surface protrusion and concavity shape that imitates the shape of clothing when the humanoid body 1 is wearing clothes.
