Description

[Technical Field]

[0001] The present invention relates to a connecting member for a doll-type toy and a model. [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 animal requires a large number of parts, and even in sophisticated doll toys, the number is limited, making it difficult to achieve. Therefore, in order to realize the movements and poses described above, it is important to realize natural movements while configuring a doll with fewer joints and parts and expanding the range of motion of the joints and the parts connected to them. Patent Document 1 proposes a configuration that uses ball joints in each joint to reproduce realistic human-like movements. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-118601 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art, ball joints are used at both ends of a connecting member to connect each part, such as an upper body part or a lower body part, thereby expanding the range of motion. Each part connected by a ball joint is rotatably connected to one end of the connecting member and moves within the spatial constraints of the part connected to the other end of the connecting member. In other words, the range of motion is limited by interference between the parts. This is because two parts connected to one connecting member abut against each other and move around the connecting member as an axis.

[0005] On the other hand, parts connected to other connecting members often move around different connecting members and are connected in positions that prevent interference between the parts, allowing them to move independently. However, depending on the movement of the parts, this can create an unnatural impression. When the upper body and torso are connected with one connecting member and the lower body and torso are connected with a different connecting member, as in the above-mentioned conventional technology, the upper body and lower body can move without interfering with each other. When the upper body and lower body move independently in this way, it can deviate from natural human movements. Vertebrates, such as humans, have a spine that extends from the upper to the lower body, and the upper and lower body move around the spine as an axis. Therefore, in a structure in which the upper body and lower body are connected with different connecting members as described above, they can move on different axes, allowing for unnatural movements that are not possible in vertebrates.

[0006] The present invention provides a mechanism for realizing natural movements of a human being, for example, in a doll-type toy, while suppressing interference between parts connected to one connecting member. [Means for solving the problem]

The present invention also provides a doll-type toy, comprising a spherical first connecting portion that connects to a first part, a spherical second connecting portion that connects to a second part, and a spherical third connecting portion that connects to a third part, wherein the first connecting portion, the second connecting portion, and the third connecting portion are included in a connecting member that is formed as a single part in a rod shape. The first connecting portion is formed by swelling spherically around one end of the rod-shaped connecting member, the third connecting portion is formed by swelling spherically around the other end of the rod-shaped connecting member, the second connecting portion is formed by swelling spherically around a predetermined position between the one end and the other end of the rod-shaped connecting member, and the first part and the second part are provided in contact with each other, and the second part and the third part are provided in contact with each other.

[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] <External appearance of doll-type toy> First, an example of the external configuration of a doll-type toy 100 according to this embodiment will be described with reference to Figures 1A and 1B. Figure 1 shows the external front view of the doll-type toy 100. Figure 2 shows the external side view of the doll-type toy 100. Note that the up / down, left / right, and front / back arrows indicate the orientation of the doll-type toy in the figure, and this also applies to the other figures.

[0013] The doll toy (doll body) 100 includes a head 101, a chest 102, arms 103a and 103b, an abdomen 104, a waist 105, a skirt 106 as a clothing accessory, and legs 107a and 107b. The doll toy 100 is a movable doll toy such as a movable figure, and each part can be moved within a limited range created in relation to other members. The head 101 is connected to the chest 102 by a ball joint. Arms 103 including a right arm 103a and a left arm 103b are further connected to the chest 102 by a ball joint, and the abdomen 104 is connected at the bottom. The waist 105 is connected to the abdomen 104. The detailed configurations of the chest 102, abdomen 104, and waist 105 will be described later. Legs 107 including a right leg 107a and a left leg 107b are connected to the waist 105 and are covered with a skirt 106.

[0014] In the following, the upper body including the head 101, chest 102, and arms 103 will be referred to as the upper body. The lower body including the waist 105 and legs 107a and 107 will be referred to as the lower body. The upper body and lower body are connected via the abdomen 104. The chest 102, abdomen 104, and waist 105 will also be collectively referred to as the torso. As will be described in detail below, the upper body including the chest 102, and the lower body including the abdomen 104 and waist 105 (i.e., the torso) are connected by a connecting member, which is a single part.

[0015] <Detailed structure of the fuselage> Next, the detailed configuration of the body of the doll-type toy 100 according to this embodiment will be described with reference to Fig. 3. Fig. 3(a) shows a side view of the body after assembly. Fig. 3(b) shows a side view of the body after disassembly.

[0016] The torso is made up of a chest 102, an abdomen 104, and a waist 105. Each part is made up of one or more parts. The chest 102, abdomen 104, and waist 105 are movably connected by a connecting member 300, which corresponds to the spine of the doll-type toy 100.

[0017] The connecting member 300 is formed as one part having three spherical connecting portions (ball joints) 301 to 303. The connecting portion (first connecting portion) 301 is movably connected to the chest portion 102, which is the first part, by a ball joint. The connecting portion (second connecting portion) 302 is movably connected to the abdomen portion 104, which is the second part, by a ball joint. The connecting portion (third connecting portion) 303 is movably connected to the waist portion 105, which is the third part, by a ball joint.

[0018] In the configuration described above, the first part and the second part are in contact with each other and are connected to one connecting member 300, so their range of motion is limited by movable interference with each other. Furthermore, the second part and the third part are in contact with each other and are connected to one connecting member 300, so their range of motion is limited by movable interference with each other. Therefore, although the first part and the third part are not in contact with each other and are installed separately, they are indirectly connected via the second part and the connecting member 300 and therefore move in relation to each other.

[0019] In other words, these configurations make it possible to limit unnatural movements that vertebrates cannot perform. For example, when the first part is rotated to the right, the second part that is in contact with the first part will also rotate to a certain extent, allowing for natural movements. Note that because there is some space where the ball joints are installed and there is also some play in the range of motion between the parts, it is possible to rotate the parts in opposite directions. However, because the parts are in contact with each other, they cannot be rotated to an extent that would give an unnatural impression.

[0020] Furthermore, connecting portion 302 is disposed between connecting portions 301 and 303 and is formed in a spherical shape smaller than at least one of the other connecting portions 301 and 303. This ensures a range of motion around the abdomen while reducing interference between the parts that contact each other. Furthermore, the part of abdomen 104 is formed smaller than at least one of chest 102 and waist 105, which are in contact with it above and below. In other words, according to this embodiment, the second part, which limits the range of motion of at least one of the first and third parts, is formed relatively small and connected to connecting member 300 with a small ball joint, allowing the second part to move in accordance with the movements of the first and third parts. This reduces interference between the parts as much as possible and achieves a wider range of motion.

[0021] Furthermore, the connecting member 300 may be formed in a curved state as shown in FIG. 3. By forming it in this manner, a configuration having three ball joints can be realized in a smaller space in the vertical direction. Note that if a larger installation area can be secured, the connecting member may be formed in a linear shape or in other shapes. In addition, the shape is similar to the spine of a vertebrate such as a human, from the waist to the chest, and it is possible to realize movements more similar to those of a vertebrate.

[0022] <Cross-sectional side view of the fuselage> Next, a side cross-sectional view of the body of the doll-type toy 100 according to this embodiment will be described with reference to Fig. 4. As shown in Fig. 4, the chest 102, which is a first part, the abdomen 104, which is a second part, and the waist 105, which is a third part, are formed by a single part, the connecting member 300.

[0023] The connecting part 301 is movably fitted into a recess 102a provided in the chest 102. The connecting part 302 is attached in such a way that two parts 104a and 104b constituting the abdomen 104 sandwich the connecting part 302 from the front and back. As shown in FIG. 4, even when the parts 104a and 104b are attached, there is some space (play) in front and behind the connecting part 302, and this space can be used to allow the abdomen 104 to rotate up and down and left and right, and to rotate in accordance with the movements of the chest 102 and the waist 105. The connecting part 303 is movably fitted into a recess 105a provided in the waist 105.

[0024] <Twisting motion> Below, with reference to Figures 5 and 6, we will explain examples of movements (postures) that can be achieved with a configuration in which three ball joints are used in one connecting member according to this embodiment. First, with reference to Figure 5, we will explain the twisting movement of the body of the doll-type toy 100 according to this embodiment. Figure 5(a) shows a front view of the body showing the normal position before the twisting movement. Figure 5(b) shows a front view of the body after the twisting movement. 500 indicates the center line.

[0025] The torso shown in FIG. 5(a) shows a state in which the chest 102, abdomen 104, and waist 105 are facing forward and are not rotated left or right around the connecting member 300. On the other hand, FIG. 5(b) shows a state in which the chest 102 is rotated to the right of the doll-type toy 100 from the state shown in FIG. 5(a), and the abdomen 104 is accordingly rotated to the right at a smaller rotation angle than the chest 102. That is, in FIG. 5(b), the chest 102 rotates to the right at the largest rotation angle around the connecting member 300 as the rotation axis, the abdomen 104 rotates to the right at a smaller rotation angle than the chest 102, and the waist 105 is not rotated. Therefore, a posture in which the doll-type toy 100 is gradually twisted to the right toward its upper body can be expressed with a natural impression. Furthermore, because each connecting part is a ball joint configured symmetrically, a similar twisting motion can also be realized in the left-hand direction. Although the description has been given here in a state where the waist portion 105 is not rotated, the waist portion 105 can also be rotated in the left and right directions in the same manner.

[0026] This allows for natural twisting movements of a human being, a vertebrate, in the left-right direction. If the connecting member only has ball joints at both ends, the abdomen 104 is fixed to the connecting member 300, preventing it from rotating in tandem with the left-right movements of the chest 102 (the upper body part) and the waist 105 (the lower body part), creating an unnatural appearance. Furthermore, if the chest 102 and abdomen 104 are connected by one connecting member and the abdomen 104 and waist 105 are connected by another connecting member, the chest 102 and waist 105 can move along their own axes, resulting in unnatural movements. Furthermore, if the chest 102, abdomen 104, and waist 105 are realized as two parts, the abdomen 104 is incorporated into each part, potentially limiting the range of motion due to interference between the upper and lower parts. The connecting member 300 of this embodiment, on the other hand, provides three ball joints in one part, thereby alleviating the above-mentioned problems.

[0027] <Backward bending movement> Next, the backward bending motion (upper body arching) of the torso of the doll-type toy 100 according to this embodiment will be described with reference to Fig. 6. Fig. 6(a) shows a side view of the torso showing the normal posture before the backward bending motion. Fig. 6(b) shows a side view of the torso after the backward bending motion. 600 indicates the center line.

[0028] The torso shown in FIG. 6(a) shows a state in which the chest 102, abdomen 104, and waist 105 are facing forward and are not rotated up or down around the connecting member 300 as an axis. On the other hand, FIG. 6(b) shows a state in which the chest 102 is rotated upward from the state shown in FIG. 6(a) toward the upper part of the doll-type toy 100, and the abdomen 104 is accordingly rotated upward at a smaller rotation angle than the chest 102. That is, in FIG. 6(b), the chest 102 rotates upward at the largest rotation angle around the connecting member 300 as the rotation axis, the abdomen 104 rotates upward at a smaller rotation angle than the chest 102, and the waist 105 is not rotated. Therefore, a posture in which the upper body of the doll-type toy 100 is gradually bent backward (arched) upward can be expressed with a natural impression. Furthermore, since each connecting part is a ball joint configured symmetrically in the upper and lower directions, a forward bending motion can also be realized in the downward direction. Although the description has been given here in a state where the waist portion 105 is not rotated, the waist portion 105 can also be rotated in the vertical direction in the same manner.

[0029] Thus, according to this embodiment, the three parts can be rotated in a natural manner not only in the left-right direction but also in the up-down direction, as explained using Fig. 5. Furthermore, although the left-right and up-down directions have been exemplified in this embodiment, because the parts are ball joints, they can also be rotated in other directions within the range of interference between the parts.

[0030] As described above, the doll-type toy 100 according to this embodiment includes a spherical first connecting portion that connects to the first part, a spherical second connecting portion that connects to the second part, and a spherical third connecting portion that connects to the third part. The first connecting portion, second connecting portion, and third connecting portion are included in a connecting member formed as a single part. This provides a mechanism for realizing natural movements of a human or the like in a doll-type toy while minimizing interference between parts connected to a single connecting member.

[0031] In the above embodiment, the first connecting portion is formed at one end of the connecting member, the second connecting portion is formed between the first connecting portion and the third connecting portion, and the third connecting portion is formed at the other end of the connecting member. With this configuration, the first part and the third part are indirectly connected via the second part connected to the second connecting portion between the first connecting portion and the third connecting portion, and mutual movable interference can be reduced compared to when the parts are in direct contact. Meanwhile, by forming the second connecting portion and the second part to be relatively small in size, the range of motion of the first part and the third part can be expanded.

[0032] <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. In the above-described embodiment, a connecting member having three connecting portions has been described. However, this is not intended to limit the present invention, and a configuration having more connecting portions may be used. This allows for more precise movements to be achieved.

[0033] Furthermore, although the above embodiment has been described as an example in which the connecting member is applied to a spine part, this is not intended to limit the present invention and the connecting member may be used for other parts. For example, it may be used for an animal's tail, neck, wings, etc. Furthermore, although the connecting member according to the above embodiment has been described as being formed in a curved shape, the shape may be modified depending on the conditions of the spatial area in which it is installed. For example, it may be formed in a linear shape if the installation area allows.

[0034] Furthermore, the shape of the doll toy (doll-type toy) is not particularly limited, and includes various shapes with clothing, such as people, animals, robots, insects, and dinosaurs. [Explanation of symbols]
