[0021] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. These embodiments are not intended to limit the invention as defined in the claims, and the combinations of features described in the embodiments are not necessarily all essential to the invention. Two or more features from the plurality of features described in the embodiments may be combined arbitrarily. Furthermore, the same or identical structures are labeled with the same reference numerals, and repeated descriptions are omitted.

[0022] Figure 1A and Figure 1B This is a perspective view of the head accessory 2 of the humanoid body 1 according to the embodiment. In this embodiment, the humanoid body 1 is a model toy that imitates a quadrupedal animal (e.g., a dog), but it can also be a model toy that imitates a bipedal animal (e.g., a human).

[0023] Furthermore, in this instruction manual, when describing the positional relationships of various parts, terms such as front, back, left, right, top, bottom, inside, and outside are sometimes used. However, these descriptions are relative to the humanoid figure 1. For example, front corresponds to the front side of the humanoid figure 1, and back corresponds to the back side of the humanoid figure 1.

[0024] Furthermore, in this specification, the various constituent elements of the humanoid body 1 are described as "accessories." However, the concept of accessories refers not only to the smallest unit that the user can disassemble, but also to accessories assembled from two or more of these smallest units. Therefore, the term "accessory" in the following description can be replaced with "component," "piece," "member," "structure," "assembly," etc., or it can be omitted. For example, head accessory 2 can be described as head part, head member, head structure, head assembly, etc., or it can simply be described as head. The same applies to other accessories described later.

[0025] The head accessory 2 includes an upper jaw accessory 201 and a lower jaw accessory 202. The upper jaw accessory 201 and the lower jaw accessory 202 are held in place of the main body of the head accessory 2, details of which will be described later. The lower jaw accessory 202 is held in a position where it can rotate relative to the main body of the head accessory 2. When the upper jaw accessory 201 and the lower jaw accessory 202 are close together, they form a closed mouth state (see reference). Figure 1A Furthermore, the upper jaw accessory 201 and the lower jaw accessory 202 form an open mouth state when they are separated from each other (see reference). Figure 1B ).

[0026] Figure 2 This is an exploded perspective view of head component 2. In addition to the upper jaw component 201 and the lower jaw component 202, head component 2 also includes components 203 to 211. Head component 2 can be constructed by directly / indirectly connecting these components 201 to 211 and by connecting adjacent components in a fixed or rotatable (or swinging) manner. For ease of understanding, the connection relationships between these components are indicated by dashed lines in the figure.

[0027] The concept of connection between components can encompass various connection methods, such as installation, connection, and fixation of one component relative to another. For ease of understanding, this specification uses descriptions based on implementation methods, but the invention is not strictly limited to these descriptions (which can be replaced with the same description). The same applies to other descriptions.

[0028] Component 203 forms the left side of head component 2 (also referred to as the left head component). Component 204 forms the right side of head component 2 (also referred to as the right head component). These components 203 and 204 are interconnected. The maxillary component 201 is held below these components 203 and 204, details of which will be described later.

[0029] Accessory 205 forms the upper front part of head accessory 2 (also referred to as the front head accessory). Accessory 206 is installed at the front end of the front head accessory 205 to form a nose (also referred to as a nose accessory). These accessories 205-206 are held or even clamped by the aforementioned interconnected left head accessory 203 and right head accessory 204.

[0030] Accessory 207 is installed on the upper left side of the front head accessory 205, forming an ear (also referred to as the left ear accessory). Accessory 208 is installed on the upper right side of the front head accessory 205, forming another ear (also referred to as the right ear accessory).

[0031] Accessories 209 and 210 are interconnected to support the rear portion of the jaw accessory 202 (both can be referred to as support accessories) so that the jaw accessory 202 can rotate. These accessories 209 and 210 are mounted on the front head accessory 205 and are held or clamped by the interconnected left head accessory 203 and right head accessory 204.

[0032] Additionally, accessory 211 forms a tongue and is fixed relative to jaw accessory 202 (also referred to as tongue accessory).

[0033] In this embodiment, accessories 203 to 210 form the main body of the head accessory 2, and relative to the main body of the head accessory 2, the upper jaw accessory 201 and the lower jaw accessory 202 that form the mouth are retained.

[0034] Furthermore, when assembling head accessory 2, accessories 209 and 210 are shaped to be held by accessories 203 and 204. This operation can be performed before accessories 209 and 210 are installed on the front head accessory 205. That is, accessories 201-204 and accessories 209-211 can be installed together relative to the front head accessory 205.

[0035] In addition, in this embodiment, accessories 201 to 211 are made of resins such as polystyrene, but other materials with the desired strength, such as wood or metal, may also be used.

[0036] Figure 3A This is a cross-sectional view of head accessory 2 in its closed state. Figure 3B This is a cross-sectional view of the head accessory 2 in its open state. To facilitate understanding of the structure, the outlines of the head accessory 2 body, upper jaw accessory 201, lower jaw accessory 202 and tongue accessory 211 are represented by dashed lines in the figure, and the shaft parts P1 and P2 and the retaining parts H1 and H2, which will be described later, are represented by solid lines.

[0037] like Figure 2 , Figure 3A and Figure 3B As shown, a first shaft portion P1 and a second shaft portion P2 located behind the first shaft portion P1 are provided at the front of the upper jaw accessory 201. The shaft portions P1 and P2 are provided in pairs on the left and right sides, respectively, extending in the left-right direction.

[0038] like Figure 3A and Figure 3B As shown, a first retaining portion H1 is provided in accessory 203 (and accessory 204). In this embodiment, the retaining portion H1 is a circular opening that retains the shaft portion P1 by means of fitting, and the retaining portion H1 retains the shaft portion P1 of the upper jaw accessory 201 in such a way that the upper jaw accessory 201 can rotate relative to the head accessory 2 body.

[0039] In addition, such as Figure 3A and Figure 3B As shown, a second retaining part H2 is provided in accessory 203 (and accessory 204). The retaining part H2 is an opening in the shape of an elongated hole that holds the shaft part P2 in a sliding position. Thus, the retaining part H2 can limit the rotation area (or movable range) of the upper jaw accessory 201 based on the rotation of the retaining part H1.

[0040] Depend on Figure 3A and Figure 3B As can be seen, in this embodiment, the shaft P2 is located behind the shaft P1 (the retaining part H2 is located behind the retaining part H1), thereby enabling the upper jaw accessory 201 to rotate appropriately and its rotation area to be appropriately limited.

[0041] A locking part E1 is provided at the rear of the tongue accessory 211, which can be locked to the rear of the upper jaw accessory 201. As described above, in this embodiment, the tongue accessory 211 is fixed relative to the lower jaw accessory 202. Therefore, by Figure 3A and Figure 3B It can be seen that when the lower jaw accessory 202 is rotated to change the mouth from a closed state to an open state, the locking part E1 is locked onto the rear part of the upper jaw accessory 201. As a result, the rear part of the upper jaw accessory 201 moves downwards along with the rotation of the lower jaw accessory 202. On the other hand, when the lower jaw accessory 202 is rotated to change the mouth from an open state to a closed state, the upper jaw accessory 201 is pressed down from below by the tongue accessory 211, thereby causing the rear part of the upper jaw accessory 201 to move upwards.

[0042] Based on the above structure, the maxillary accessory 201 moves partially up and down as the mandibular accessory 202 rotates. In this embodiment, the up-and-down movement of the maxillary accessory 201 is illustrated using the tongue accessory 211. However, since the tongue accessory 211 is fixed relative to the mandibular accessory 202, the mandibular accessory 202 and the tongue accessory 211 can also be formed as a single unit in another embodiment. Alternatively, the tongue accessory 211 can be omitted, allowing the mandibular accessory 202 to also perform the functions of the tongue accessory 211.

[0043] Furthermore, the aforementioned structure in which the upper jaw accessory 201 moves partially up and down in sync with the rotation of the lower jaw accessory 202 is not limited to this embodiment, and other structures may also be used. For example, in this embodiment, the retaining part H2 is provided as an elongated hole-shaped opening, but the retaining part H2 may also be provided as a circular opening (similar to the retaining part H1), and the upper jaw accessory 201 is made of a flexible material (e.g., rubber). With such a structure, the upper jaw accessory 201 will also move partially up and down in sync with the rotation of the lower jaw accessory 202.

[0044] According to this embodiment, the palatal accessory 201 is held to the head accessory 2 body in such a way that when the mouth changes from a closed state to an open state, the rear part of the palatal accessory 201 descends. With this configuration, the unnatural feeling of the palate falling off when the mouth changes from a closed state to an open state can be eliminated, and a natural deformation of the humanoid body 1 can be appropriately achieved.

[0045] The invention is not limited to the above-described embodiments and can be modified and altered in various ways within the scope of the invention's intent.
