[0010] 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.
[0011] In addition, in each drawing, the up, down, left, and right directions on the paper surface will be used in the description of the present embodiment as the up, down, left, and right directions of the parts (or components) in this embodiment. Note that in the embodiments described below, the present invention will exemplify ABS (acrylonitrile-butadiene-styrene) resin and SBC (styrene-butadiene copolymer, styrene-based special transparent resin) as molding materials, but is not limited to these, and does not exclude the use of other materials (thermoplastic resins such as polyethylene, thermosetting resins, soft resins, metals, etc.).
[0012] <Appearance of doll toy> First, an example of the external configuration of the doll toy 100 according to this embodiment will be described with reference to Figures 1A and 1B. Figure 1A shows the external front view of the doll toy 100. Figure 1B shows the external side view of the doll toy 100. Note that the up / down, left / right, and front / back arrows indicate the orientation of the doll 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 103r and 103l, an abdomen 104, a waist 105, and legs 107r and 107l. The doll toy 100 is a movable doll toy such as an assembly-type movable figure, and each part can be moved within a limited range created by its relationship with other members. The head 101 is connected to the chest 102 by a spherical connecting member (hereinafter also referred to as a ball joint). Arms 103, including a right arm 103r and a left arm 103l, are further connected to the chest 102 by spherical connecting members, and the abdomen 104 is connected at the bottom. The detailed structure of the chest will be described later. The waist 105 is connected to the abdomen 104. Legs 107, including a right leg 107r and a left leg 107l, are connected to the waist 105, and the waist 105 is covered with clothing such as a skirt.
[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 107r and 107l 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. In the following, as joint structures according to this embodiment, a shoulder joint structure that connects the arm 103b to the chest 102 via a spherical connecting member (ball joint), and a hip joint structure that connects the arm 103b to the waist 105 will be described. However, this is not intended to limit the present invention, and the joint structures described below are not limited to shoulder joints and hip joints, and can also be applied to other joints, such as elbow joints and knee joints.
[0015] <Upper body (chest) structure> Next, the detailed configuration of the chest 102 of the upper body of the doll toy 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2(a) is an exploded perspective view of the chest 102, abdomen 104, and waist 105 of the upper body. Fig. 2(b) is an exploded view of the chest 102 including the chest joint and shoulder joint. The arms 103r and 103l are connected to the shoulder joint, but Fig. 2 omits the arm 103r.
[0016] As shown in Figure 2(a), the chest 102 is connected to the abdomen 104 by a spherical connecting portion (ball joint). That is, the chest joint according to this embodiment movably connects the chest 102 to the abdomen 104 by a ball joint. However, this is not intended to limit the present invention, and connecting portions of other shapes may be used instead of the spherical connecting portion.
[0017] As shown in FIG. 2(b), chest 102 is composed of multiple parts 201 to 207. Part 201 is the base part for multiple joints. Part 202 is inserted into part 201 from below to form the chest joint. Furthermore, with part 202 inserted into part 201, parts 203r and 203l are fitted in from both sides. This prevents part 202 from falling off part 201.
[0018] Parts 204r and 204l are connected to parts 203r and 203l, respectively, and together with part 201 form a shoulder joint. Furthermore, arms 103r and 103l are connected to parts 204r and 204l. Only arm 103l is shown in FIG. 2(b). Part 205, which is an external part of the chest, and part 206, which is an external part of the upper back, are assembled so as to sandwich parts 201 to 203, thereby locking and fixing each part.
[0019] A recess is further formed on the top of part 201. A spherically shaped connecting part of part 207 is connected to this recess. The neck joint of the doll toy 100 is formed by connecting part 201 and part 207. As described above, according to this embodiment, the chest joint, shoulder joint, and neck joint can be realized using part 201, which serves as the base of multiple joints, and various movements can be made possible with fewer parts. Furthermore, when a spherically shaped connecting part is used in each joint, it can rotate in all directions within the spatial limitations of the other parts.
[0020] <Structure of the shoulder joint connected to the chest joint> Next, the detailed configuration of the shoulder joint connected to the chest joint according to this embodiment will be described with reference to FIG. 3. FIG. 3(a) is a perspective view showing a portion of the configuration that constitutes the shoulder joint in the arm 103l. Here, this will be referred to as a shoulder joint unit 300. FIG. 3(b) is a cross-sectional view showing an example of the cross-sectional structure of the shoulder joint unit 300 in FIG. 3(a). The cross-sectional view in FIG. 3(b) is a view of the cross section taken along line A-A' in FIG. 3(a) as viewed from the direction of the arrow. FIG. 3(c) shows an example of an exploded view of the shoulder joint unit 300. The following description will be given with reference to FIGS. 3(a) to 3(c).
[0021] In Fig. 3, shoulder joint 300 is made up of a combination of part 203l, part 204l (second part), part 301 (third part), and part 302 (first part). Although the symbols r and l used to distinguish between left and right parts are omitted in Fig. 3, Fig. 3 shows the configuration of the left arm, and it is assumed that similar parts are used in right arm 103r.
[0022] Part 203l has spherical connecting portion 203la formed at one end and opening 203lb formed at the other end. Spherical connecting portion 204la formed at one end of part 204l is connected to opening 203lb so as to be rotatable, for example, in the direction indicated by arrow 321 in FIG. 3(b). Part 204l also has opening 204lb formed at the other end, to which protrusion 302a formed on the upper end side of part 302 is connected so as to be rotatable, for example, in the direction indicated by arrow 322. The range of this rotation is restricted by engagement between ends 204lc and 204ld of a recess provided on the connecting surface of part 204l with part 302 and protrusion 302c provided below protrusion 302a of part 302. Furthermore, the connection portion between opening 204lb and protrusion 302a is covered by cover members 301a and 301b on the upper end side of part 301 so as not to be exposed to the outside. The shape of the upper ends of cover members 301a and 301b is arc-shaped to correspond to the trajectory of connecting portion 204la when part 204l rotates relative to part 302. This prevents the trajectory of connecting portion 204la from being obstructed when part 204l rotates.
[0023] Here, part 301 is integrally formed and has no seams on its surface. This makes it possible to visually inconspicuous the connecting parts of doll toy 100, which has a structure that exposes the shoulders and bare skin, while eliminating the sense of incongruity caused by seams and creating an impression of bare skin. Furthermore, part 301 has a cavity (first cavity, through-hole) formed inside, connecting the upper and lower openings. Part 204l and part 302 are inserted into this cavity through the upper opening of part 301, with opening 204lb and protrusion 302a connected. The above-mentioned protrusion 302a is formed at the upper end of part 302, and the other end is configured as a cylindrical member to be inserted into the cavity. Furthermore, step 302b (first step) is provided in the cylindrical member, and the inner diameter of the cylindrical member becomes narrower or different toward the other end via step 302b. Although only one step is provided in Fig. 3, multiple steps may be provided by varying the inner diameter of the cylindrical member by three or more steps. A step corresponding to step 302b is also provided in the cavity within part 301 (step 301d: second step), and the engagement between step 301d and step 302b determines the insertion depth of part 302 into part 301. At this time, the bottom end of part 302 is maintained in a state protruding from the cavity of part 301. Other parts that make up arm 103l of doll toy 100 are connected to the member protruding from the opening on the bottom side of part 302.
[0024] Figure 4 is a diagram illustrating the rotational movement of part 204l and part 302. Figure 4(a) is a diagram showing the configuration of part 204l from the side opposite to the side shown in Figure 3(c), and a recess 204le defined by ends 204lc and 204ld is formed along opening 204lb on the connecting surface of part 204l with part 302. Figure 4(b) is a diagram showing the configuration of part 302 from the side opposite to the side shown in Figure 3(c), and protrusion 302c is indicated by a dotted line.
[0025] 4(c) shows the rotation range when part 204l and part 302 are rotatably connected and rotate. Protrusion 302c engages with recess 204le and is movable within the range from end 204lc to 204ld, thus defining the rotation range of part 204l relative to part 302 (or vice versa).
[0026] <Lumbar structure> Next, the detailed configuration of the waist 105 of the doll toy 100 according to this embodiment will be described with reference to Fig. 5. Fig. 5(a) is an exploded perspective view of the chest 102, abdomen 104, and waist 105. Fig. 5(b) is an exploded view of the waist 105 including the waist joints and hip joints, and parts of the legs 107r and 107l.
[0027] 5(a), the waist portion 105 is connected to the abdomen 104 by a spherical connecting portion (ball joint). This allows the waist portion 105 to be connected to the abdomen 104 in a rotatable manner.
[0028] Next, as shown in FIG. 5(b), the waist 105 is composed of at least a plurality of parts 501 to 504. The part 501 is a part that serves as the base of a plurality of movable mechanisms. The part 502 is rotatably connected to the part 501. The part 502 is a part of the clothing of the toy doll 100. More specifically, the part 502 is the pants part of the toy doll 100. Therefore, in the toy doll 100 according to this embodiment, the pants part moves on an axis that is independent of the other movable mechanisms and other parts. The part 502 is further connected to a part 504 that represents the buttocks and a skirt, which is part of the clothing of the toy doll 100. Therefore, the part 504 also rotates in accordance with the rotation of the part 502. The parts 503r and 503l are each sequentially connected to a cylindrical portion formed at one end of the part 501. This forms the hip joint of the toy doll 100. Parts 505r and 505l that are part of the legs 107r and 107l are further connected to the parts 503r and 503l, respectively.
[0029] <Leg movement mechanism> Next, the leg moving mechanism 505 connected to the hip joint according to this embodiment will be described with reference to Figure 6. Figure 6(a) shows an exploded view of part 505r of leg 107r. Figure 6(b) shows a cross-sectional view of part 503r and part 505r connected together. Note that the configuration of the right leg moving mechanism will be described with reference to Figure 6, but the configuration of the left leg is similar and therefore will not be described again.
[0030] As shown in FIG. 6(a), part 505r of leg 107r further includes parts 601 to 604. Part 601 (fourth member) is the base of part 505r, and rotatably receives spherical part 602 in a receiving portion at the top. The rotation direction of part 602 (fifth member) is the direction indicated by arrow 621 in FIG. 6(b). When part 602 is housed in part 601, part 602 can be connected to part 503r via connecting portion 602a. Part 602 has a spherical shape and functions as a ball joint with respect to part 503r. Parts 601 and 602 are housed in a cavity (second cavity, through-hole) 603a provided inside part 603 (sixth member). Cavity 603a is formed so as to connect the lower opening of part 603, which receives parts 601 and 602, with the upper opening for exposing connecting portion 602a of part 602 to the outside of part 603.
[0031] A protrusion 603b is formed inside cavity 603a, and protrusion 603b engages with recess 601a provided in part 601, thereby positioning parts 601 and 602 within part 603. This positioning mechanism aligns connecting portion 602a of part 602 with the position of the upper opening of part 603, ensuring connection with part 503r.
[0032] Here, the part 603 is integrally formed and has no seams on the surface. This makes it possible to make the connecting parts visually inconspicuous in the doll toy 100, which has a structure that exposes the legs and bare skin, while eliminating the sense of incongruity caused by seams and giving the impression of bare skin.
[0033] As shown in FIG. 6(b), part 503r and part 602 are assembled to form a ball joint, which is provided inside leg 107r. Therefore, leg 107r connected to part 602 can rotate in all directions relative to the hip joint, as indicated by arrow 621, within the limits of the other parts. In addition, the cylindrical portion at the bottom of part 601 is rotatably inserted into a recess in part 604. Therefore, in leg 107r, part 604 and the parts below it can rotate relative to part 601 in the direction of arrow 522.
[0034] Next, the structure of the movable mechanism 505 of the leg 107 will be further described with reference to Fig. 7. Fig. 7(a) is a diagram showing a partial configuration of the movable mechanism 505, in which part 601 and part 602 are connected and housed in part 603. Part 602 exposes connecting portion 602a to the outside from an opening in part 601 through an upper opening in part 603, making it possible to receive part 503r.
[0035] FIG. 7(b) is a cross-sectional view taken along line B-B' in FIG. 7(a) as viewed from above. From FIG. 7(b), it can be seen that when parts 601 and 602 are housed within part 603, part 602 is sandwiched between parts 601 and 603 and cannot fall out of part 603. Specifically, part 602 is sandwiched between the inner wall of the opening of part 601 and the inner wall of the cavity of part 603. The inner wall of the opening of part 601 has a shape that corresponds to the spherical outer shape of part 602, allowing part 602 to rotate within part 601. It can also be seen that in the state shown in FIG. 7(b), the recessed portion of part 601 and the protruding portion 603b of part 603 are engaged and positioned.
[0036] As described above, the toy parts according to this embodiment are configured for exposed parts, such as the shoulders and legs of an assembled doll-like toy body. In either configuration, by forming the exposed parts as a single unit, it is possible to eliminate the seams and dividing lines that would normally occur when combining two parts. This eliminates the visual discomfort felt by the viewer and allows for a natural, bare skin feel. Furthermore, the integrated parts form joints, house connecting members made up of at least two parts inside, and cover the connecting members to prevent the joints from being exposed to the outside. While this embodiment describes the application to bare skin parts such as the shoulders and legs of a toy body, it can also be applied to parts where seams and dividing lines would create a sense of discomfort, such as when depicting clothing of a single color.
