[Effects of the Invention]

[0007] According to the present invention, it is possible to provide a model component with a novel mechanism. [Brief explanation of the drawing]

[0008] [Figure 1] A diagram showing an example of the external configuration of a doll toy according to one embodiment. [Figure 2] A diagram showing the assembly of model parts in one embodiment. [Figure 3] A diagram showing the assembly of model parts in one embodiment. [Figure 4] A cross-sectional view of a model part in one embodiment, cut along line AA in Figure 3. [Figure 5] A diagram showing how the left arm is connected to a model part in one embodiment. [Modes for carrying out the invention]

[0009] The embodiments will be described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention as defined in the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more of the features described in the embodiments may be combined arbitrarily. Furthermore, identical or similar configurations will be given the same reference numeral, and redundant descriptions will be omitted.

[0010] An example of the configuration of a model toy MT according to one embodiment of the present invention will be described. In this embodiment, a doll-type model toy (humanoid robot) is used as an example to describe the model toy MT, but there is no intention to limit the present invention, and the present invention can be applied to various models such as people, animals, robots, insects, dinosaurs, weapons, ornaments, etc. Hereinafter, the doll-type model toy MT may be referred to as "doll toy MT".

[0011] Figure 1 shows an example of the external configuration of the doll toy MT in this embodiment. Figure 1 shows the front view of the doll toy MT, and the X, Y, and Z arrows in the figure indicate the forward, left, and upward directions of the doll toy MT, respectively. In this specification, when describing the positional relationship of each part, terms such as front, back, left, right, top, and bottom may be used, but these expressions are relative to the doll toy MT. For example, front corresponds to the front side of the doll toy MT, and back corresponds to the rear side of the doll toy MT.

[0012] The doll toy MT of this embodiment comprises a head 1, a chest 2, an abdomen 3, a right shoulder 4R, a left shoulder 4L, a right arm 5R, a left arm 5L, a waist 6, a right leg 7R, and a left leg 7L. The head 1 is connected to the upper part of the chest 2. The right shoulder 4R is rotatably connected to the right side of the chest 2, and the right arm 5R is rotatably connected to the right shoulder 4R. Similarly, the left shoulder 4L is rotatably connected to the left side of the chest 2, and the left arm 5L is rotatably connected to the left shoulder 4L. The right hand 8R is connected to the tip of the right arm 5R, and the left hand 8L is connected to the tip of the left arm 5L. The abdomen 3 is connected to the lower part of the chest 2, and the waist 6 is connected to the lower part of the abdomen 3. The chest 2 and abdomen 3 constitute the torso of the doll toy MT. The right leg section 7R and the left leg section 7L are rotatably connected to the waist section 6.

[0013] In this embodiment, the right shoulder portion 4R and the left shoulder portion 4L of the doll toy MT are provided with shoulder joints that are rotatably connected to the side of the chest portion 2 (torso portion), and to which the right arm portion 5R and the left arm portion 5L are rotatably connected. The arms 5R and 5L connected to the shoulder joints are made heavy by, for example, ornaments. Therefore, the model part 100 used as the shoulder joint is required to have a configuration that does not easily change the orientation of the joint (i.e., the orientation of the arms 5R and 5L relative to the chest portion 2) due to the weight of the heavy object. Below, the model part 100 constituting the left shoulder portion 4L (shoulder joint) is given as an example, and its configuration example is shown while explaining the assembly of the model part 100 step by step. Figures 2 and 3 show the assembly of the model part 100 constituting the left arm portion 5L (shoulder joint).

[0014] Referring to Figure 2, the model part 100 comprises a first part 10, a second part 20, and a third part 30. Figure 2 shows how the first part 10, the second part 20, and the third part 30 are connected to each other. Figures 2(a) and 2(b) show the model part 100 viewed from different angles to illustrate the structure of the connection between the first part 10 and the second part 20, and the connection between the first part 10 and the third part 30.

[0015] A protrusion 11a (first protrusion) and a wall portion 12a (first wall portion) for connecting the second part 20 are provided on the first side portion 10a (the side portion in the +X direction) of the first part 10. The protrusion 11a protrudes in the +X direction from the first side portion 10a of the first part 10, and is fitted into an opening 21 of the second part 20 described later. The wall portion 12a is arranged around the protrusion 11a at a distance from the protrusion 11a so as to at least partially surround the outer surface of the protrusion 11a. A space corresponding to the thickness of the wall portion 22 of the second part 20 is provided between the protrusion 11a and the wall portion 12a to allow the wall portion 22 (second wall portion) of the second part 20, which will be described later, to fit therein. Although the wall portion 12a of the present embodiment is partially provided with a notch to facilitate connection of the second part 20, the present invention is not limited thereto, and the wall portion 12a may be configured to surround the entire outer surface of the protrusion 11a.

[0016] A protrusion 11b (second protrusion) and a wall portion 12b (fourth wall portion) for connecting the third part 30 are provided on the second side portion 10b (the side portion in the -X direction) of the first part 10 opposite to the first side portion 10a. The protrusion 11b protrudes in the -X direction from the second side portion 10b of the first part 10, and is fitted into an opening 31 of the third part 30 described later. The wall portion 12b is arranged around the protrusion 11b at a distance from the protrusion 11b so as to at least partially surround the outer surface of the protrusion 11b. A space corresponding to the thickness of the wall portion 32 of the third part 30 is provided between the protrusion 11b and the wall portion 12b to allow the wall portion 32 (fifth wall portion) of the third part 30, which will be described later, to fit therein. Although the wall portion 12b of the present embodiment is partially provided with a notch to facilitate connection of the third part 30, the present invention is not limited thereto, and the wall portion 12b may be configured to surround the entire outer surface of the protrusion 11b.

[0017] The second part 20 is a component connected to the first side portion 10a of the first part 10. On the side portion of the second part 20 on the first part 10 side, there are provided a wall portion 22 (second wall portion) that defines (forms, configures) an opening 21 into which the protruding portion 11a of the first part 10 is fitted, and a wall portion 23 (third wall portion) that at least partially surrounds the outer side surface of the wall portion 22. Between the wall portion 22 and the wall portion 23, a space corresponding to the thickness of the wall portion 12a of the first part 10 is provided for the wall portion 12a on the first side portion 10a of the first part 10 to be fitted into. Note that each of the wall portion 22 and the wall portion 23 of the present embodiment may have a notch in a part thereof to facilitate connection to the first part 10.

[0018] When connecting the first part 10 and the second part 20 to each other, the protruding portion 11a on the first side portion 10a of the first part 10 is fitted into the inner side surface of the wall portion 22 of the second part 20 (that is, the opening 21 defined by the wall portion 22). Then, the wall portion 12a on the first side portion 10a of the first part 10 is fitted between the wall portion 22 and the wall portion 23 of the second part 20. Further, the wall portion 22 of the second part 20 is fitted between the protruding portion 11a and the wall portion 12a on the first side portion 10a of the first part 10. Thereby, the second part 20 is rotatably connected to the first side portion 10a of the first part 10 with the protruding portion 11a of the first side portion 10a as a rotation shaft.

[0019] The third part 30 is a component connected to the second side portion 10b of the first part 10, and has the same configuration as the second part 20. On the side portion of the third part 30 on the first part 10 side, there are provided a wall portion 32 (fifth wall portion) that defines (forms, configures) an opening 31 into which the protruding portion 11b of the first part 10 is fitted, and a wall portion 33 (sixth wall portion) that at least partially surrounds the outer side surface of the wall portion 32. Between the wall portion 32 and the wall portion 33, a space corresponding to the thickness of the wall portion 12b of the first part 10 is provided for the wall portion 12b on the second side portion 10b of the first part 10 to be fitted into. Note that each of the wall portion 32 and the wall portion 33 of the present embodiment may have a notch in a part thereof to facilitate connection to the first part 10.

[0020] When connecting the first part 10 and the third part 30, the projection 11b on the second side portion 10b of the first part 10 fits into the inner surface of the wall portion 32 of the third part 30 (i.e., the opening 31 defined by the wall portion 32). The wall portion 12b on the second side portion 10b of the first part 10 fits between the wall portion 32 and the wall portion 33 of the third part 30. The wall portion 32 of the third part 30 fits between the projection 11b on the second side portion 10b of the first part 10 and the wall portion 12b. As a result, the third part 30 is rotatably connected to the second side portion 10b of the first part 10, with the projection 11b on the second side portion 10b as the pivot axis.

[0021] The second part 20 and the third part 30 are connected to each other so as to sandwich the first part 10. Figure 3 shows the state in which the first part 10, the second part 20, and the third part 30 are connected to each other. The projection 11a, which is the pivot axis of the second part 20 relative to the first part 10, and the projection 11b, which is the pivot axis of the third part 30 relative to the first part 10, are arranged on the same line. Therefore, the connection between the second part and the third part 30 is rotatable relative to the first part 10 around the axis on which the projections 11a to 11b extend.

[0022] Furthermore, the protrusion 24 provided on the lower part of the second part 20 and the protrusion 34 provided on the lower part of the third part 30 are connected to each other to form a single protrusion CP. This protrusion CP is the part that fits into the recess 51 provided on the upper end of the left arm 5L, as will be described later.

[0023] Here, Figure 4 is a cross-sectional view of the model part 100 in Figure 3, cut along line AA, showing the cross-section (YZ section) of the connection between the first part 10 and the second part 20. In this embodiment, the model part 100 is structured such that, in addition to fitting the projection 11a of the first part 10 into the opening 21 (inner surface of the wall 22) of the second part 20, the wall 12a of the first part 10 is fitted between the wall 22 and wall 23 of the second part 20, and the wall 22 of the second part 20 is fitted between the projection 11a and wall 12a of the first part 10. In this way, by fitting the first part 10 and the second part 20 in multiple stages around the projection 11a, even if the heavy arm 5L is connected to the second part 20, the change in the relative posture between the first part 10 and the second part 20 due to the weight of the arm 5L can be reduced. In other words, even if the weight of the arm section 5L increases due to the attachment of decorations, it is possible to maintain the desired posing applied to the doll toy MT. The connection state between the first part 10 and the third part 30 is the same as the connection state between the first part 10 and the second part 20.

[0024] Referring to Figure 3, the model part 100 further comprises a fourth part 40. The fourth part 40 is a component for securing the connection between the second part 20 and the third part 30. For example, the fourth part 40 is attached across the second part 20 and the third part 30. This can prevent the second part 20 and the third part 30 from separating. In this embodiment, the fourth part 40 is configured in a ring shape and is attached to the lower part of the connection between the second part 20 and the third part 30.

[0025] As described above, the model part 100, which is configured as the left shoulder part 4L (shoulder joint), is connected to the left arm part 5L as shown in Figure 5. Specifically, the left arm part 5L is connected to the model part 100 by fitting the convex part CP of the connecting body between the second part 20 and the third part 30 into the concave part 51 provided on the upper end of the left arm part 5L. The model part 100 is also attached to the left side of the chest part 2 of the doll toy MT. Specifically, the convex connecting part 13 provided on the first part 10 is connected to the left side of the chest part 2. Here, the model part 100 is not limited to the left shoulder part 4L, but may also be applied to the right shoulder part 4R (shoulder joint). The model part 100 may also constitute the hip joint of the doll toy MT. In this case, the first part 10 (connecting part 13) of the model part 100 is connected to the waist 6, and the protruding part CP of the connecting body of the second part 20 and the third part 30 is connected to the legs (left leg 7L, right leg 7R).

[0026] As described above, in the model part 100 of this embodiment, the first side portion 10a of the first part 10 is provided with a projection 11a and a wall portion 12a, and the second part 20 is provided with a wall portion 22 and a wall portion 23, thereby fitting the first part 10 and the second part 20 in multiple stages. Similarly, the second side portion 10b of the first part 10 is provided with a projection 11b and a wall portion 12b, and the third part 30 is provided with a wall portion 32 and a wall portion 33, thereby fitting the first part 10 and the third part 30 in multiple stages. By applying the model part 100 configured in this way to the shoulder joint and hip joint of a model toy MT (doll toy), even if heavy arms and legs are connected, the change in the orientation of the joint due to the weight of the heavy objects is reduced, making it possible to maintain the desired posing applied to the doll toy MT.
