In FIG. 1, the leg part 14 and the arm part 15 on the left side are illustrated, but the same applies to the right side.

In this specification, when explaining the positional relationship of each part, front (front), rear (rear), left (left side), right (right side), upper (upper), lower (lower) , inside (inside), outside (outside), etc., these expressions are relative to the doll body 1 as a reference. For example, the front side corresponds to the front side of the doll body 1, and the rear side corresponds to the back side of the doll body 1.

Each of the above-described site parts 11-15 (including parts 141-144 and 151-154) can be configured by connecting one or more parts (component parts) to each other. For example, the leg parts 14 (parts 141 to 144) are formed by directly/indirectly connecting a plurality of constituent parts, more specifically, two adjacent constituent parts are fixedly or rotatably connected. (or oscillating) by being connected. Similarly, for example, arm parts 15 (parts 151 to 154) are configured by directly/indirectly connecting a plurality of component parts.

It should be noted that the concept of connection between parts can include various connection modes such as attaching one part to another part, coupling, fixing, and the like. For ease of understanding, expressions in accordance with the embodiments are used in this specification, but the present invention is not strictly limited to those expressions (the expressions can be replaced with similar expressions). ). The same applies to other expressions.

Further, in this specification, individual components of the doll body 1 are expressed as "parts", but the concept of "parts" includes minimum units that can be disassembled by the user, as well as combinations of two or more of them. Also point Therefore, the expression "part" in the following description may be replaced with "component, piece", "member", "structure", "assembly", etc. or may be omitted. For example, the leg part 14 may be expressed as a leg part, a leg member, a leg structure, a leg assembly, etc., or simply as a leg. Similarly, the arm part 15 may be expressed as an arm part, an arm member, an arm structure, an arm assembly, or the like, or simply as an arm. This also applies to other parts.

The parts 142F and 142G can form a substantially continuous surface, as will be described in more detail below.

The part 142H is a thigh exterior part that forms another part of the exterior of the thigh part 142, and is configured to be engageable with the parts 142C and 142D. Since the part 142H is positioned above the parts 142C and 142D behind the doll body 1, it can also be called a buttocks part.

Parts 142I-142K realize the hip joint structure of the doll body 1. FIG. The part 142I supports the part 142B from above. The part 142J is connected to the part 142I so as to be rotatable in the left-right direction (or inward-outward direction). The part 142K connects the part 142J so as to be rotatable in the front-rear direction. Also, the part 142K is connected to the waist 13 on the side opposite to the part 142J. With such a structure, the leg parts 14 are held so as to be rotatable in the front-back direction and/or the left-right direction with respect to the waist part 13 .

The part 142L is a thigh exterior part that forms another part of the exterior of the thigh part 142, and is rotatably held from below with respect to the part 142J inside the upper part of the thigh. Although the details will be described later, the part 142L can be said to be an inner thigh upper part located inside the part 142A, and is also a sealing part for sealing the internal structure and making it invisible from the outside. I can also say.

(2-3. Structure of lower leg parts)
The part 143A is a crus exterior part that forms part of the exterior of the crus part 143, and is attached to the inside of the upper part of the part 141B, so it can also be called an inner crus upper part. The part 143B is a crus exterior part that forms another part of the exterior of the crus part 143, and is attached to the upper outer side of the part 141B, so it can also be called an outer crus outer upper part. The parts 143A and 143B are interconnected and form a substantially continuous surface at their rear portions to present a calf-like portion.

The part 143C is a crus exterior part that forms another part of the exterior of the crus part 143, and is also called a crus lower part because it is engaged with the lower part of the part 141B by fitting. I get it. The part 143D is connected to the part 143C from below, and rotatably supports the foot part 144 (see FIG. 1), although the description is omitted here.

The part 143E is a crus exterior part that forms a part of the exterior of the crus part 143, and is attached to the upper front part of the part 141B, so it can also be called an upper crus front part.

Parts 143F to 143H are decorative parts attached to part 143E. The part 143F is attached from the front to the part 143E. The part 143G is rotatably attached to the part 143F from above. Part 143H is attached to the inner wall of part 143G.

Although each of the parts constituting the leg part 14 has been described individually here, some of them may be integrally constructed. For example, two parts (parts 142B and 142I, parts 143G and 143H, etc.) that are fixedly connected to each other and do not involve changing their relative positions may be integrally molded.

(3. Rotation mode of leg parts)
FIG. 3A shows a partial cross-sectional view in a side view of the state in which the leg part 14 is extended (the state in which the crus part 143 is positioned in front of its range of motion). FIG. 3B shows a state in which the leg part 14 is partially rotated (a state in which the knee part 141 and the lower leg part 143 are rotated backward with respect to the thigh part 142). A partial cross-sectional view is similarly shown. FIG. 3(C) similarly shows a partial cross-sectional view of a state in which the leg part 14 is bent (a state in which the crus part 143 is positioned at the rear of its range of motion).

For ease of understanding, the figure shows the actual structure of the lower leg part 143, the outlines of the parts 141C (or 141D) and 142 with dashed lines, and the cross-sectional structures of the parts 141A, 142E and 142G. indicates

As shown in FIGS. 3A to 3C, the part 141A includes a first extension 141A1 and a second extension 141A2 extending into the thigh part 142. As shown in FIGS. The first extending portion 141A1 is provided so as to be able to engage with a part 142E rotatably sandwiched between the parts 142C and 142D. The second extension 141A2 is provided in front of the first extension 141A1, and the part 142G is attached to the second extension 141A2. Further, the part 141A is provided with a substantially elliptical opening 142A3, and the aforementioned parts 142A and 142B (see FIG. 2) are inserted and held through this opening part 141A3. The portion connecting parts 142A and 142B and passing through opening part 141A3 is shown as portion 91 in the figure.

According to such a configuration, the parts 142A and 142B are held so as to be rotatable with respect to the parts 141C and 141D, and the movable range due to the rotation is restricted by inserting the opening 142A3. be. Therefore, the range of motion of the thigh part 142 with respect to the knee part 141 is narrower than the range of motion of the lower leg part 143 with respect to the knee part 141 .

Here, when the state of FIG. 3A is changed to the state of FIG. If you think about. In this case, the first extending portion 141A1 is separated from the inner wall of the part 142E as the rear lower thigh part. Therefore, the part 142E can be recessed with respect to the contours of the parts 142C and 142D as the rear upper thigh parts. On the other hand, the part 142G as the thigh front lower part is attached to the second extension 141A2. Therefore, in this case, the part 142G rises with respect to the external shape of the part 142F as the front upper part of the thigh.

Furthermore, when the state of FIG. 3B changes to the state of FIG. Consider the case where the part 143 is rotated. As mentioned above, in the state of FIG. When the rear portion comes into contact with the part 142E, the part 142E is depressed by the pressure accompanying the contact.

Therefore, according to such a structure, the range of motion of the lower leg part 143 is widened, and a posture (for example, a sporty posture such as a crouching pose) in which the lower leg part 143 and the thigh part 142 are brought into close contact is formed. It becomes possible.

Next, when the state shown in FIG. 3C is returned to the state shown in FIG. Think about if you let In this case, the first extending portion 141A1 contacts and presses the inner wall of the part 142E as the rear lower thigh part. Therefore, the part 142E is pushed outward, thereby forming a continuous surface with the parts 142C and 142D as the rear upper thigh parts. On the other hand, the part 142G as the thigh front lower part is attached to the second extension 141A2. Therefore, in this case, the part 142G forms a continuous surface with the part 142F as the front upper thigh part.

FIG. 4A shows the hip joint structure (parts 142I to 142K) of the doll body 1 and the peripheral portion of the thigh part 142 in the closed leg posture. FIG. 4(B) shows a leg-opened posture in which the thigh part 142 is rotated in the direction of arrow A11 from the state shown in FIG. 4(A).

As described above, the part 142L is rotatably held from below with respect to the part 142J on the inside of the upper part of the thigh, and the internal structure is sealed inside the part 142A to make it invisible from the outside. Here, in the closed-leg posture (see FIG. 4A), most of the part 142L is stored in the parts 142C and 142F. On the other hand, in the open-leg posture (see FIG. 4(B)), the tip of the part 142L slides while being engaged with the parts 142A (and 142C) The part is positioned inside the part 142A.) Therefore, the part is turned in the direction of the arrow A12 to be partially exposed, and along with that, the part 142A protrudes outward.

In general, a gap may be created between two parts that are relatively rotatable relative to each other so that their interference is avoided, and the internal structure may be visible through the gap. According to the above-described configuration, the part 142L seals the internal structure inside the part 142A to make it invisible from the outside even in the open-leg posture, which is advantageous in improving the design of the doll body 1. sell.

(4. Summary of leg parts configuration)
One of the parts constituting the doll body 1 according to the embodiment is the leg part 14, and the leg part 14 includes a knee part 141, a thigh part 142, and a lower leg part 143. , provided. The thigh part 142 is rotatable with respect to the knee part 141, and in this embodiment, there are two rear upper thigh parts (parts 142C and 142D) and a lower rear thigh part (part 142E). The crus part 143 is rotatable with respect to the knee part 141, and is rotatable to a position where the rear part of the crus part 143 comes into contact with the rear lower part of the thigh (part 142E). It is attached to the knee part 141 . In this embodiment, the range of motion of the thigh part 142 with respect to the knee part 141 is narrower than the range of motion of the lower leg part 143 with respect to the knee part 141 .

Here, the thigh rear lower part (part 142E) is held so that the following holds. That is, when the thigh part 142 is rotated with respect to the knee part 141 in a direction to approach the lower leg part 143, the rear lower thigh part (part 142E) changes to the upper rear thigh part ( parts 142C and 142D). Further, when the thigh part 142 is rotated with respect to the knee part 141 in a direction to move away from the lower leg part 143, the rear lower thigh part (part 142E) changes to the upper rear thigh part ( forming a continuous surface with parts 142C and 142D).

In this embodiment, the knee part 141 includes a first extension 141A1 extending into the thigh part 142 . When the thigh part 142 is rotated with respect to the knee part 141 in a direction to approach the crus part 143, the first extension 141A1 extends along the inner wall of the rear lower thigh part (part 142E). so that the lower posterior thigh part (part 142E) is recessable relative to the upper posterior thigh part (parts 142C and 142D). Further, when the thigh part 142 is rotated with respect to the knee part 141 in a direction to move away from the lower leg part 143, the first extension part 141A1 moves toward the rear lower thigh part (part 142E). so that the lower posterior thigh part (part 142E) forms a continuous surface with the upper posterior thigh part (parts 142C and 142D). According to such a configuration, when the thigh part 142 is rotated, the aforementioned aspect of the thigh rear lower part (part 142E) (that is, the thigh by the thigh rear lower part (part 142E) The recesses for the upper posterior thigh parts (parts 142C and 142D) and the formation of continuous surfaces with the upper posterior thigh parts (parts 142C and 142D) can be properly realized.

According to this embodiment, a person who can form a posture in which the lower leg part 143 is in close contact with the lower leg part 143 and the thigh part 142 (for example, a sporty posture such as a crouching pose). Form 1 can be realized. Therefore, according to this embodiment, it is advantageous to diversify the postures that the doll body 1 can form.

Further, in the present embodiment, the thigh part 142 further includes a front upper thigh part (part 142F) and a front lower thigh part (part 142G). The lower front thigh part (part 142G) is held so that the following holds. That is, when the thigh part 142 is rotated with respect to the knee part 141 in a direction to approach the crus part 143, the front lower thigh part (part 142G) changes to the front upper thigh part ( part 142F). Further, when the thigh part 142 is rotated with respect to the knee part 141 in a direction to move away from the lower leg part 143, the front lower thigh part (part 142G) changes to the front upper thigh part ( part 142F) to form a continuous surface.

In this embodiment, the knee part 141 further includes a second extension 141A2 extending into the thigh part 142 . The thigh front lower part (part 142G) is held by the second extension 141A2. According to such a configuration, when the thigh part 142 is rotated, the above-described aspect of the thigh front lower part (part 142G) (that is, the thigh by the thigh front lower part (part 142G) Prominence on the front upper part of the thigh (part 142F) and formation of a continuous surface with the front upper thigh part (part 142F)) can be appropriately realized. As a result, it is possible to express the tension of the thighs (a mode close to the movement of the muscles of the human body) when the lower leg part 143 and the thigh part 142 are brought close to each other. can be more advantageous for diversification of postures that can be formed.

Regarding the part 141A, in the present embodiment, the extending portions 141A1 and 141A2 are individually provided to prevent interference with other parts. Alternatively, extensions 141A1 and 141A2 may be provided as a single extension.
