Next, with reference to FIG. 2, the assembly configuration of the arm portion 103 of the toy model 100 according to this embodiment will be described. FIG. 2(a) shows the left arm portion 103a removed from the toy model 100. FIG. 2(b) shows an exploded perspective view of the left arm. Here, the configuration of the left arm portion 103a will be explained. Note that the configuration of the right arm portion 103b is also the same as that of the left arm portion 103a, so a description thereof will be omitted.

As shown in FIG. 2(a), the left arm portion 103a is connected to the body portion 102 by a spherical second connection portion of the movable member 201. As shown in FIG. Further, a first connecting portion formed in a C-shape is provided at one end of the movable member 201, and the connecting portion is connected to the left arm portion 103a. Therefore, the left arm portion 103a is connected to the body portion 102 by the second connection portion so as to be rotatable in all directions within the limits of other members, and is rotatable in the vertical direction by the first connection portion. Concatenated.

As shown in FIG. 2(b), the left arm section 103a is composed of a shoulder joint, an upper arm section 203, and a forearm section 204. The shoulder joint includes a movable member 201 of the shoulder joint and shoulder parts 202a, 202b, and 202c. As for the assembly configuration of these parts, shoulder parts 202a and 202b are assembled, and shoulder part 202c is assembled thereto. A rod member formed at the lower part of the assembled shoulder part 202 is fitted into the upper arm part 203, and the upper arm part 203 is further fitted into the forearm part 204.

The left arm portion 103a is rotatably connected to the body portion 102 by fitting the second connecting portion of the movable member into the member of the body portion 102. Note that the movable member 201 may be assembled to the body portion 102 first, and then to the left arm portion 103a including the shoulder part 202.

<Configuration of movable members>
Next, with reference to FIG. 3, the detailed configuration of the movable member 201 according to this embodiment will be described. FIG. 3(a) shows a perspective view of the movable member 201. FIG. 3(b) shows a side view of the movable member 201.

The movable member 201 includes a first connecting portion 301, a rod portion 302, a second connecting portion 303, and a rail portion 305. The first connecting portion 301 is formed in a C-shape at one end of the rod portion 302, and is rotatably connected to a shaft 401 of a shoulder part (receiving portion) 202, which will be described later. On the other hand, the second connecting portion 303 is formed in a spherical shape at the other end of the rod portion 302 and is rotatably connected to the parts of the body portion 102 . Note that there is no intention to limit the second connecting portion 303 to a spherical connecting portion, and the second connecting portion 303 may be a connecting portion having another shape. For example, the second connection portion may be formed in a C-shape like the first connection portion 301, or may be formed in a ring shape or other shapes.

Further, the first connecting portion 301 includes two edge portions 304a and 304b located at the tip of the C-shape. The edge portions 304a and 304b are located near the C-shaped opening. The distance between the two end edges is narrower than the width of the axis 401 of the shoulder part 202. In addition, a convex overpass portion is formed inside the edge portions 304a and 304b, as shown in the dotted line area 307. In other words, it functions as a crossing part when connecting the movable member 201 to the shaft 401, and prevents it from falling off from the shoulder part 202. Therefore, at least the first connecting portion 301 of the movable member 201 is formed using an elastic member so as to bend in response to the pressure generated when connected to the shaft 401 or when rotated.

Further, a rail portion 305 is formed on the outside of the first connecting portion 301 along a part of the outer shape of the C-shaped first connecting portion 301 . In this embodiment, the rail portion 305 is provided outside the lower edge portion 304b of the C-shape. However, this is not intended to limit the present invention, and for example, as an alternative or additional , may be formed outside the edge portion 304a. The rail portion 305 prevents the first connecting portion 301 from falling off the shoulder part 202, and is formed as a groove that receives the insertion portion 402 formed in the shoulder part 202a. Note that the rail portion 305 is an example of a sliding portion provided along the rotational direction of the first connecting portion 301, and its shape is particularly limited as long as it can slidably hold the insertion portion 402. isn't it. By inserting the insertion portion 402 deep into the rail portion 305, the movable member 201 is configured not to easily fall off from the shoulder part 202. Note that the rail portion 305 and the insertion portion 402 may be provided in reverse. That is, the rail portion 305 may be provided on the shoulder part 202 and the insertion portion 402 may be provided on the movable member 201.

Furthermore, a convex portion 306 is formed on the inner wall of the first connecting portion 301 . The protrusion 306 is fitted into a recess 406 formed in the shaft 401. By fitting the convex portion 306 into the concave portion 406 in this manner, it is possible to prevent the movable member 201 from falling off in the front-rear direction. Note that the recess 406 is formed along a part of the circumference of the outer circumferential surface of the shaft 401, and the protrusion 306 is formed to match the shape. Therefore, since the convex portion 306 rotates along the recess 406 when the movable member 201 rotates about the shaft 401, the rotation of the movable member 201 is not inhibited.

<Structure of the receiving part>
Next, with reference to FIG. 4, a detailed configuration of the shoulder part 202, which is a receiving part according to this embodiment, will be described. FIG. 4(a) shows a side view of the shoulder part 202a, and FIG. 4(b) shows a side view of the shoulder part 202b. FIG. 4(c) shows a perspective view of the shoulder part 202.

As shown in FIG. 4(a), the shoulder part 202a on the back side is formed to include a shaft portion 401a and an insertion portion 402. Further, as shown in FIG. 4(b), the shoulder part 202b on the front side is formed to include a shaft portion 401b and a rod portion 403. When the shaft portions 401a and 401b are connected, a shaft 401 is formed. The body portion 102 is rotatably fitted into the upper arm portion 203.

The insertion section 402 is a member inserted into the rail section 305. Here, an example will be described in which the insertion part 402 is formed only on one shoulder part 202a, but the insertion part 402 is provided on the shoulder part 202b, the rail part 305 is provided on the shoulder part 202b side of the movable member 201, and the insertion part 402 is provided on the shoulder part 202b side of the movable member 201. 402 and rail portions 305 may be formed on both sides. Thereby, the function of preventing the movable member 201 from falling off the shoulder part 202 can be improved. In that case, the width of the rail portion 305 formed on the movable member 201 also needs to be defined to be wide enough to accommodate the insertion portions provided on both sides.

FIG. 4(c) shows a state in which the shoulder parts 202a, 202b, and 202c are assembled. When shoulder parts 202a and 202b are assembled, shaft portions 401a and 401b are connected to form shaft 401. The shaft 401 is formed in a cylindrical shape, and a recess 406 is formed in a part thereof. As described above, the convex portion 306 formed on the movable member 201 is rotatably fitted into the concave portion 406 . As shown in FIG. 4(c), the insertion portion 402 is provided on one side (back side) of the shoulder part 202. However, as described above, the insertion portion 402 may be provided on the other side (front side) or may be provided on both sides. In this embodiment, the shaft portions 401a and 401b constituting the shaft 401 have different diameters, but they may have the same diameter. However, when the insertion part 402 is provided only on one side of the shoulder part 202, the diameter of the shaft part 401a adjacent to the insertion part 402 should be formed smaller than the diameter of the shaft part 401b, as shown in FIG. 4(c). This allows you to save space.

Furthermore, as shown at 407a and 407b, holes are formed on the outside of the shaft 401 for connecting other parts. The holes 407a, 407b are formed from the outside of the shoulder parts 202a, 202b toward the inside of the shaft 401, and can receive rods of other parts. Note that in this embodiment, the holes 407a and 407b are provided in alignment with the shaft 401, but this is not intended to limit the present invention, and the holes may be provided in other positions of the shoulder part 202, for example.

<Assembly procedure>
Next, with reference to FIG. 5, a procedure for assembling the movable member 201 according to this embodiment to the shoulder part 202 will be described.

As shown in FIG. 5(a), the movable member 201 is assembled to the assembled shoulder part 202 along the direction of the arrow. At this time, the C-shaped first connecting portion 301 and rail portion 305 are assembled by adjusting their positions so that they fit into the shaft 401 and the insertion portion 402, respectively. Here, it is inserted diagonally from above in accordance with the shape of the insertion portion 402.

FIG. 5(b) shows a cross-sectional view of the shoulder joint. As shown in FIG. 5(b), the movable member 201 is connected to the shoulder part 202 so as to be rotatable about the shaft 401 in the direction of the dotted arrow. Further, by rotating the movable member 201 with respect to the shoulder part 202, the insertion portion 402 can enter deep into the rail portion 305, and the function of preventing the movable member 201 from falling off can be enhanced. In other words, in the position where the movable member 201 is connected to the shoulder part 201, there is a possibility that the movable member 201 will fall off, but as the insertion part 402 rotates from this position so as to enter deep into the rail part 305, the movable member 201 may fall off. It is possible to reduce the possibility of

<Assembling the arm>
Referring to FIGS. 6 and 7, assembly of the left arm portion 103a to the body portion 102 will be described. 6 and 7 show the upper body of the toy model 100, and only the shoulder joint portion is shown in cross section so that the internal structure can be seen. Here, a procedure will be described in which the movable member 201 is first assembled to the body part 102, and then the arm part 103 is assembled.

As shown in FIG. 6(a), a spherical second connecting portion 303 of the movable member 201 is rotatably connected to the body portion 102. As shown in FIG. Thereafter, the shaft 401 of the left arm portion 103a and the insertion portion 402 are inserted diagonally from above in accordance with the positions of the first connection portion 301 and the rail portion 305 of the movable member 201, and are connected. That is, as shown in FIG. 6(a), the toy model 100 is assembled with the left arm portion 103a raised upward.

Thereafter, as shown in FIG. 6(b), the left arm portion 103a rotates downward (in the direction of the dotted arrow) about the shaft 401 and moves to the normal position. Note that this movement naturally occurs after the left arm portion 103a is assembled to the movable member 201 due to its weight. On the other hand, regarding the connection part of the movable member 201 to the shoulder part 202, the strength of the fitting is increased by adjusting the outer circumference of the shaft 401 to be larger, so that it does not move naturally to the normal position due to the weight of the left arm part 103a. may be configured. In this case, it is necessary to apply a predetermined force to move the left arm portion 103a to the normal position.

FIG. 7 shows a state in which the left arm portion 103a has been assembled to the body portion 102 and then moved to the normal position. An enlarged view of the dotted line area 701 is shown in a dotted line area 702. As illustrated, when the left arm portion 103a moves to the normal position, the insertion portion 402 enters deep into the rail portion 305. In this state, when a force is applied in the direction of the solid line arrow, the insertion portion 402 is caught on the inner wall of the rail portion 305, which is the outer wall of the first connection portion 301, at the portion indicated by the dotted line area 703, preventing the left arm portion 103a from coming off. It can be prevented.

As explained above, the movable structure according to the present embodiment includes a receiving part having a cylindrical shaft and a movable member having a first connecting part rotatably connected to the shaft. Alternatively, the movable member is formed with a rail portion that is provided along a part of the outer shape of the first connecting portion. In this manner, according to the present embodiment, a novel mechanism can be provided in a movable structure or a toy model. More specifically, in a movable structure or a toy model, it is possible to easily assemble the parts, and it is possible to suitably reduce the possibility of parts falling off (missing).
