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.

[0010] An example of the configuration of a model toy 10 according to one embodiment of the present invention will be described. In this embodiment, a doll-type model toy (humanoid robot) will be described as an example of the model toy 10, but this is not intended to limit the present invention, and the present invention can be applied to various models such as people, animals, robots, insects, dinosaurs, weapons, and ornaments. Hereinafter, the doll-type model toy 10 may be referred to as the "doll toy 10."

An example of the configuration of the model part 20 will be described below with reference to Figs. 2 to 5. Figs. 2 to 3 show exploded views of the model part 20. Fig. 2 shows a view of the model part 20 seen from diagonally above the front, and Fig. 3 shows a view of the model part 20 seen from diagonally below the front. Fig. 4 shows an example of the configuration of the model part 20 after assembly. As shown in Figs. 2 to 4, the model part 20 of this embodiment includes a first part 21, a second part 22, and a third part 23.

[0014] The first part 21 constitutes at least a part of the chest 12 of the doll toy 10 (specifically, a connecting part that is connected to the second part 22 of the abdomen 13). The first part 21 of this embodiment has a spherical part 21a (first spherical part), an extending part 21c (first extending part), and an attached part 21d, which are integrated (combined) together.

[0015] Spherical portion 21a is a portion that rotatably fits into the upper portion of through-hole 23a of third part 23, and is connected to through-hole 23a of third part 23 by a ball joint. A recess 22b into which spherical portion 22a of second part 22 rotatably fits is provided in the lower portion of spherical portion 21a (i.e., a part on the opposite side from extended portion 21c). Extended portion 21c is a portion that extends upward from spherical portion 21a. Mounted portion 21 is a portion to which exterior parts of chest part 12, etc. are attached, and is provided in the upper portion of extended portion 21c (i.e., a part on the opposite side from spherical portion 21a).

[0016] The second part 22 constitutes at least a part of the waist 15 of the doll toy 10 (specifically, a connecting part that is connected to the first part 21 of the chest 12). The second part 22 of this embodiment has a spherical part 22a (second spherical part), an extending part 22b (second extending part), and an attached part 22c, which are integrated (combined) together.

[0017] Spherical portion 22a is a portion that rotatably fits into recess 21b provided in spherical portion 21a of first part 21, and is connected to recess 21b of first part 21 by a ball joint. Extended portion 21b is a portion that extends downward from spherical portion 22a. Mounting portion 22c is a portion to which right leg 16R and left leg 16L are attached, and is provided at the bottom of extending portion 21b (i.e., a part opposite spherical portion 22a). An opening 22d to which left leg 16L is attached is provided on the left side of mounting portion 22c, and similarly, an opening (not shown) to which right leg 16R is attached is provided on the right side of mounting portion 22c.

[0018] The third part 23 constitutes at least a part of the abdomen 13 of the doll toy 10. The third part 23 of this embodiment has a cylindrical member with a through-hole 23a extending in the up-down direction (Z direction). A protrusion 23b (support portion) for supporting the spherical portion 21a of the first part 21 is provided at the top of the through-hole 23a of the third part 23, as will be described later, and the spherical portion 21a of the first part 21 is rotatably fitted into the protrusion 23b. Furthermore, the spherical portion 22a of the second part 22, which is fitted into the recess 21b of the first part 21, is inserted from the bottom of the through-hole 23a of the third part 23.

[0019] Next, the assembly of the model component 20 including the first part 21, the second part 22, and the third part 23 will be described step by step with reference to Figures 5 to 7. Figures 5 to 7 show cross-sectional views (YZ cross-sectional views) of the model component 20.

[0020] Fig. 5 shows how first part 21 is connected to third part 23. As shown in Fig. 5, protrusions 23b for supporting spherical portion 21a are provided on the inner surface of through hole 23 of third part 23. Spherical portion 21a of first part 21 is inserted from the upper side (first side) of through hole 23a of third part 23, and is supported by protrusions 23b provided on the inner surface of through hole 23a, thereby being rotatably fitted into the upper part of through hole 23a.

[0021] FIG. 6 shows how the second part 22 is connected to the first part 21. As shown in FIG. 6, the diameter of the spherical portion 22a of the second part 22 is smaller than the diameter of the spherical portion 21a of the first part 21 and smaller than the diameter of the through-hole 23a of the third part 23. A recess 21b is provided at the bottom of the spherical portion 21a of the first part 21. The spherical portion 22a of the second part 22 is inserted into the through-hole 23a of the third part 23 from the bottom (the second side opposite the first side), and the spherical portion 21a of the first part 21 is rotatably fitted into the recess 21b of the spherical portion 21a with the spherical portion 21a of the first part 21 fitted into the upper part of the through-hole 23a. In this way, the first part 21, the second part 22, and the third part 23 of the model component 20 are connected to each other, as shown in FIG. 7.

[0022] As described above, the model component 20 of this embodiment includes the first part 21 having the spherical portion 21a, the second part 22 having the spherical portion 22a, and the third part 23 having the through-hole 23a. The spherical portion 21a of the first part 21 is inserted into the through-hole 23a of the third part 23 from above and rotatably fits into the through-hole 23a. The spherical portion 22a of the second part 22 is inserted into the through-hole 23a of the third part 23 from below and fits into the recess 21b provided in the spherical portion 21a of the first part 21. By using the model component 20 configured in this manner in the model toy 10, the model toy 10 can realize a variety of movements that more closely resemble those of humans and animals.
