Description

[Technical Field]

[0001] The present invention relates to a doll body, a hip joint, and a rotation mechanism. [Background technology]

[0002] To realize movements and poses similar to those of humans or animals, doll toys (doll bodies) include various joints and movable parts. However, providing a doll toy with the same number of joints as a human or other animal requires a large number of parts, and even in sophisticated doll toys, the number is limited, making this difficult to achieve. Therefore, in order to realize the movements and poses described above, it is important to configure a doll with fewer joints and parts while expanding the range of motion of the joints and the parts connected to them. Expanding the range of motion allows for greater freedom of movement and a wider variety of poses.

[0003] Patent Document 1 proposes a doll body in which a connecting member connected to the hip joint rotates between an open position and a closed position, and the legs are connected to the tip of the connecting member. With this doll body, the movements of opening and closing the legs can be realized. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-34232 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned prior art, although the connecting member is rotatable between an open position and a closed position, the movement direction is unidirectional. To realize natural movement like that of a human limb, it is desirable to be able to rotate in various directions. Meanwhile, while the hip joints can be located inside the waist, just like in a human, and natural leg movements can be realized, the movement space is limited. In other words, it is necessary to allow the legs to rotate more freely within the space limited by their relationship with other components such as the waist and skirt.

[0006] The present invention provides a mechanism for expanding the range of motion of the hip joints of, for example, a doll body, thereby realizing greater freedom of movement and a wider variety of poses. [Means for solving the problem]

At the center of the waist of the doll body a hip joint portion to be connected; a circular engaging portion provided at the rear of the hip joint portion; a connecting member having one spherical end rotatably engaged with the engaging portion; and a connecting member having a spherical end rotatably engaged with the other end of the connecting member. At the side of the hip joint and a leg portion to be connected to the connecting member, the portion between the one end and the other end being The doll body includes an L-shaped first part extending from the one end engaged with the engaging part at the rear of the waist joint part to a lower part of the waist joint part, and a rod-shaped second part extending from the lower part of the waist joint part to the side of the doll body. It will be established.

[0011] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention as claimed, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be arbitrarily combined. Furthermore, the same reference numerals are used for the same or similar components, and redundant explanations will be omitted.

[0012] <Doll body appearance> First, an example of the external configuration of a doll body 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 shows the external front view of the doll body 100.

[0013] The doll body (doll toy) 100 includes a head 101, a torso 102, arms 103, a waist 104, and legs 105 (105a, 105b). The head 101 is connected to the torso 102. The arms 103, including a right arm and a left arm, are further connected to the torso 102, and the waist 104 is connected to the lower part of the torso 102. The legs 105, including a right foot 105a and a left foot 105b, are connected to the waist 104. In the following description, the upper body including the head 101, the torso 102, and the arms 103 will be referred to as the "upper body." The waist 104 is located in the area indicated by the dotted line in FIG. 1 and includes a waist joint to which the upper body is connected and hip joints to which the left and right legs 105a, 105b are connected. In addition, decorations such as clothing for the doll body 100 may be attached to the exterior of the waist 104. These decorations may be provided integrally with the waist portion 104.

[0014] <Lower body structure> Next, an example of the configuration of the lower body of the doll body 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2(a) shows a perspective view of the lower half of the upper body with only the left leg connected, and Fig. 2(b) shows an exploded perspective view of Fig. 2(a). Both Fig. 2(a) and Fig. 2(b) are perspective views of the doll body 100 seen from below, showing the upper body with the right leg removed and the inside of the waist 104 visible. Note that the up / down, left / right, and front / back arrows indicate the orientation of the doll body in the figure, and this also applies to the other figures.

[0015] The waist portion 104 comprises a waist base member 104a and a waist decorative member 104b. The detailed configuration of the waist portion 104 will be described later using Figures 4 and 5. The legs 105 are composed of a connecting member 202b rotatably connected to connecting members 201 (201a, 201b) and a leg main body 203b. The detailed configuration of the legs 105 will be described later using Figure 3. The legs 105 are rotatably connected near the sides of the hip joints to connecting members 201 connected to the hip joints corresponding to the left and right legs a, 105b of the waist portion 104.

[0016] <Detailed leg structure> Next, the detailed configuration of the leg section 105 according to this embodiment will be described with reference to Fig. 3. Fig. 3(a) shows how the leg section 105b is connected to the waist section 104, and Fig. 3(b) is an exploded view of the leg section 105b. Both Fig. 3(a) and Fig. 3(b) show the configuration of the leg section 105b, which corresponds to the left foot, from the base to the knee. Other parts are omitted to simplify the description.

[0017] As shown in FIG. 3(a), one end of connecting member 201b is rotatably connected to the hip joint, and the other end 502b is connected to leg 105b. The other end 502b connected to leg 105b is formed in a cylindrical shape. Meanwhile, connecting portion 202b of leg 105b is formed with fitting portion 310 for receiving the cylindrical member that is the other end 502b of connecting member 201b. Therefore, leg 105b connected to the other end 502b can rotate around the cylindrical shape as an axis. This rotation mechanism is an example of a second rotation portion, and can rotate leg 105b in the front-to-rear direction 302 of doll body 100.

[0018] Furthermore, leg body 203b of leg 105b is configured so that its thigh portion can rotate in the direction of arrow 303 around the axial direction of leg 105b. This will be described in detail with reference to FIG. 3(b). Leg 105b includes a connecting portion 202b and leg body 203b. Leg body 203b includes an attachment member 305, a rotating member 306, and thigh 307. Attachment member 305 is attached to connecting portion 202b. Attachment member 305 is fitted into and fixed to connecting portion 202b. Furthermore, a lower portion of attachment member 305 is configured as a cylindrical member. A rotating member 306 is fitted into this cylindrical member so as to be rotatable (pivotable) in the direction of arrow 308. Furthermore, thigh 307 is attached to and fixed to rotating member 306. Although not shown, a configuration below the knee is connected to the lower portion of thigh 307. Therefore, the components below the thigh 307 follow the rotation of the lower part of the attachment member 305 and the rotating member 306. This rotation mechanism is an example of a third rotation unit, and can rotate the parts below the thigh of the leg 105 in the directions of arrows 303 and 308 around the axial direction of the leg. It is desirable that the parts below the knee (not shown) be configured to be rotatable at least at the knee and ankle positions.

[0019] <Detailed structure of the waist> Next, the detailed configuration of the waist portion 104 according to this embodiment will be described with reference to Fig. 4. Fig. 4(a) is a view of the waist portion base member 104a seen from above, and Fig. 4b is a view of the waist portion base member 104a seen from below. Fig. 4(c) is a perspective view seen from above, and Fig. 4(d) is a view of the doll body 100 seen from the left side.

[0020] The waist base member 104a is composed of a waist joint 401 and hip joints 402a, 402b. The waist joint 401 is a joint to which the upper body of the doll body 100 is connected, and a sphere (not shown) on the lower part of the upper body is rotatably connected. This allows the upper body to rotate around the waist. The waist joint 401 is formed in a circular shape to rotatably receive the sphere on the lower part of the upper body. The waist joint 401 is formed with a diameter slightly smaller than the diameter of the sphere on the lower part of the upper body, and because it is made of an elastic material such as plastic, it bends when pressed to receive the sphere.

[0021] Additionally, hip joints 402a and 402b corresponding to the left and right legs 105a and 105b are individually formed at the rear of the waist joint 401. That is, the left and right legs 105a and 105b are pivotally supported by separate hip joints 402a and 402b, respectively, and can be moved independently. This allows for more natural movements and a variety of poses. Furthermore, by providing the hip joints 402a and 402b at the rear of the waist 104, their shapes can be concealed by the buttocks, decorations, etc. Each of the hip joints 402a and 402b is formed in a circular shape, similar to the waist joint 401. Alternatively, as shown in FIG. 4(a), the waist joint 401 and the hip joints 402a and 402b may be formed integrally. This increases the strength of the waist joint 401 and the hip joints 402a and 402b, while also reducing the number of parts and simplifying the manufacturing process.

[0022] One end of each of the connecting members 201a and 201b is pivotally supported on each of the hip joints 402a and 402b. The other ends of the connecting members 201a and 201b are connected to the left and right legs 105a and 105b, respectively. According to this embodiment, as shown in the figure, each of the hip joints 402a and 402b is intentionally formed at the rear of the waist joint 401, offset from the center of the doll body, and one end of each of the connecting members 201a and 201b is pivotally supported thereon. Meanwhile, the other ends of the connecting members 201a and 201b are connected to the respective legs 105a and 105b near the lower side of the waist joint 401. By ensuring that the distance between the pivoted end and the other end connecting the legs 105a and 105b is as long as possible within the range of the waist 104 parts, the range of motion of the hip joints can be maximized.

[0023] Here, the connection of the connecting members 201a, 201b to the hip joints 402a, 402b will be described with reference to Figure 5. Figure 5(a) is a perspective view of the waist base member 104a seen from above, and Figure 5(b) is a perspective view seen from below, showing how the connecting members are attached.

[0024] The connecting members 201a and 201b each have a spherical end (spherical body) 501a, 501b and a cylindrical other end 502a, 502b. As shown in FIG. 5(b), the connecting member 201b is L-shaped from the one end 501b to the other end 502b. That is, the connecting members 201a and 201b according to this embodiment are L-shaped so as to extend from the rear of the waist joint 401 to the corresponding side of the waist joint 401 in accordance with the left and right legs 105a, 105b. This ensures that the distance from one end (center of rotation) of the pivotally supported connecting member to the other end to which the legs are connected is as long as possible within the space of the waist 104. The connecting member 201a is similarly shaped.

[0025] It should be noted that the present invention does not intend to limit the connecting member to an L-shape. The L-shape was determined based on the configuration of doll body 100 in order to ensure the longest possible distance from one end to the other within a narrow part, such as the space inside waist section 104. Any shape can be applied to other doll bodies in relation to the respective components. In other words, any shape that ensures the longest possible distance between one end and the other within a limited space is sufficient. Furthermore, since the leg section 105 may come into contact with other components when moved, thereby limiting its range of motion, it is desirable to design the shape in consideration of movement during movement. In addition to the above conditions, it is also desirable that the shape allows the axis and spherical portion to be easily removed from the mold and that the number of parts can be reduced as much as possible (preferably with only one part). The L-shape also satisfies these conditions.

[0026] As shown in FIGS. 5(a) and 5(b), one end 501a, 501b of each connecting member 201a, 201b is attached to and pivotally supported by the hip joints 402a, 402b from below. The hip joints 402a, 402b are circular, with a diameter slightly smaller than that of the spherical ends 501a, 501b. Because the hip joints 402a, 402b are made of an elastic material such as plastic, they bend when pressed to accommodate the sphere. This allows the hip joints 402a, 402b to pivotally support the connecting members 201a, 201b. While the example described here shows the connecting members 201a, 201b being connected to the hip joints 402a, 402b from below, they may also be connected from above due to spatial constraints. In this case, it is desirable for the hip joints to be located further below the waist joints. This ensures as much space as possible for the connecting members to rotate.

[0027] <Hip joint rotation mechanism> Next, a rotation mechanism of the hip joints according to this embodiment will be described with reference to Fig. 6. The rotation mechanism of the hip joints 402a, 402b described below is an example of a first rotation mechanism.

[0028] FIG. 6(a) shows a left cross-sectional view of the waist 104, illustrating the state in which the connecting member 201b rotates in the front-to-rear direction. The dotted line 601 indicates the position of the connecting member 201b rotated forward around one end 501b pivoted on the hip joint 402b. The dotted line 602 indicates the position of the connecting member 201b rotated backward around one end 501b pivoted on the hip joint 402b. Therefore, the connecting member 201b pivoted on the hip joint 402b can achieve a range of motion in the front-to-rear direction of the doll body 100, as indicated by the dotted arrow 603. Furthermore, the leg 105b is connected to the other end 502b of the connecting member 201b so as to be rotatable further forward and backward, thereby achieving a larger range of motion for the leg 105b. The connecting member 201a can also rotate in the same way, achieving a similar range of motion.

[0029] In this way, according to this embodiment, the connecting member itself rotates in the front-rear direction around the hip joint, and the legs are further rotatably attached to the connecting member. In other words, in response to the front-rear movement of the legs, the hip joints corresponding to the bases of the legs can also rotate in the front-rear direction, naturally widening the range of motion and enabling the realization of more dynamic movements and poses.

[0030] FIG. 6(b) shows a top view of the waist 104, illustrating how the connecting members 201a and 201b rotate left and right. The dotted line 604a indicates the position of the connecting member 201a rotated to the right of the doll body 100 around the end 501a pivoted to the hip joint 402a. The dotted line 605a indicates the position of the connecting member 201a rotated to the left of the doll body 100 around the end 501a pivoted to the hip joint 402a. Therefore, the connecting member 201a pivoted to the hip joint 402a can achieve a range of motion in the left and right directions of the doll body 100, as indicated by the dotted arrow 606a. Similarly, the dotted line 604b indicates the position of the connecting member 201b rotated to the left of the doll body 100 around the end 501b pivoted to the hip joint 402b. Dotted line 605b indicates the position where connecting member 201b is rotated to the right of doll body 100 around one end 501b pivoted to hip joint 402b. Therefore, connecting member 201b pivoted to hip joint 402b can obtain a range of motion in the left-right direction of doll body 100, as indicated by dotted arrow 606b. In this way, the hip joint rotation mechanism of this embodiment allows each connecting member 201a, 201b and each leg 105a, 105b connected thereto to rotate left and right independently.

[0031] In this way, the hip joint rotation mechanism according to this embodiment pivots the spherical ends 501a, 501b on the hip joints 402a, 402b, allowing rotation not only in the front-rear direction of the doll body 100 but also in the left-right direction. While the description has been given here in terms of the front-rear and left-right directions for the sake of simplicity, since the ends 501a, 501b are spherical and the hip joints 402a, 402b are circular, it goes without saying that rotation is possible in other directions as well. In other words, the hip joint rotation mechanism according to this embodiment allows rotation in all directions within the space within the waist 104 of the doll body 100. This allows for more natural movements and a variety of poses.

[0032] For example, the hip joint configuration according to this embodiment allows for a natural pose as if straddling a motorcycle. Furthermore, by rotating the right leg of the doll body forward and bending and rotating the left leg backward, it is possible to achieve a pose with one leg bent forward, such as the stance used in track and field when jumping over a hurdle. Furthermore, by standing with the connecting members tilted inward, a more natural standing posture with the legs together can be achieved. Alternatively, by opening the connecting members outward or by rotating both connecting members in the same rightward direction, various poses can be achieved. Thus, this embodiment allows for more natural movements and a variety of poses.

[0033] As described above, the doll body according to this embodiment is characterized by comprising an upper body, a waist joint to which the upper body is connected, hip joints provided at the rear of the waist joint and corresponding to the left and right legs, connecting members each having one spherical end pivotally supported on the hip joint, and legs pivotally connected to the other end of each connecting member near both sides of the waist joint. In this way, the doll body according to this embodiment includes a first pivoting section, which allows the connecting member to pivot in multiple directions, formed by the hip joint and the connecting member, and a second pivoting section, which allows the legs to pivot in the front-to-rear direction of the doll body, formed by the connecting member and the legs. This provides a mechanism for expanding the range of motion of the hip joints in the doll body, thereby realizing greater freedom of movement and a variety of poses. Furthermore, according to this embodiment, the hip joints may each be formed in a circular shape, and one end of each connecting member may be pivotally supported on the hip joint so as to be rotatable in all directions within the space within the waist of the doll body. Furthermore, each leg may be configured to be rotatable about its axial direction (third pivoting section). Thus, according to this embodiment, in addition to the first and second rotation parts, a third rotation part may be provided to rotate the thighs and below, thereby enabling more natural movements and a variety of poses to be achieved.

[0034] <Modification> The present invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the invention. For example, in the above-described embodiment, an example in which the hip joint is provided at the rear of the waist joint is described, but this does not limit the present invention. Modified examples of the hip joint will be described using Figure 7.

[0035] As shown in FIG. 7, waist base member 700 is formed with waist joint portion 701 and hip joint portions 702a, 702b in front of waist joint portion 701. As in the above embodiment, connecting members 703a, 703b are connected to hip joint portions 702a, 702b, respectively, and one spherical end of each is pivotally supported. Thus, according to the present invention, instead of providing the hip joint portion at the rear of the waist joint portion as in the above embodiment, it may be provided at the front of the waist joint portion. For example, if the front of the waist of the doll body is heavily decorated, providing the hip joint portion in the space inside the decoration can more efficiently ensure the range of motion of the hip joint.

[0036] In addition, in the above embodiment, an example in which the connecting member is formed in an L-shape has been described, but the present invention is not limited to this, and any shape may be used as long as it can ensure as long a distance as possible between one end pivotally supported on the hip joint and the other end connected to the leg, depending on the space inside the waist (part). Furthermore, in the above embodiment, an example in which the waist joint and the two hip joints are formed integrally has been described, but they may be provided at a distance due to restrictions on other members, etc.

[0037] Furthermore, the shape of the doll toy (doll body) is not particularly limited, and includes various shapes having hip joints, such as humans, animals, robots, insects, and dinosaurs. [Explanation of symbols]
