[0006] The problem the invention aims to solve

[0007] In the aforementioned prior art, the ball and slot are engaged and connected, with the ball elastically locked relative to the slot. However, these shaft members and receiving parts in the movable structure may detach due to the tensile force generated by the movement. Therefore, to prevent these members from detaching, it is considered to make the recess on the receiving side narrower to increase the engagement force. On the other hand, increasing the engagement force may also cause problems such as difficulty in insertion during assembly.

[0008] This invention provides a new structure for movable constructs and model toys.

[0009] Solution for solving the problem

[0010] The present invention is, for example, a movable structure comprising: a receiving portion having a cylindrical shaft; and a movable member having a first connecting portion connected to the shaft in a manner rotatable relative to the shaft, wherein a sliding portion is formed in the receiving portion or the movable member and disposed along the rotational direction of the first connecting portion.

[0011] Alternatively, the present invention may be, for example, a model toy, wherein the model toy comprises: a receiving portion having a cylindrical shaft; and a movable member having a first connecting portion connected to the shaft in a manner rotatable relative to the shaft, wherein a sliding portion is formed in the receiving portion or the movable member and disposed along the rotation direction of the first connecting portion.

[0023] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Furthermore, the following embodiments are not intended to limit the invention protected by the claims, and the combination of features described in all embodiments is not necessarily essential to the invention. Two or more features from the plurality of features described in the embodiments may be arbitrarily combined. Additionally, the same or identical structures are labeled with the same reference numerals, and repeated descriptions are omitted.

[0024] <Appearance of model toys>

[0025] First, refer to Figure 1 This is an example illustrating the appearance structure of the model toy 100 in this embodiment. Figure 1 (a) indicates the front view of model toy 100. Figure 1 (b) indicates the side view of the model toy 100. Furthermore, the arrows pointing up / down, left / right, and forward / backward indicate the orientation of the model toy in the figure, as do the other figures.

[0026] The model toy 100 includes a head 101, a torso 102, arms 103, legs 104, and decorative parts 105 constituting the main body. In this embodiment, a humanoid robot is described as an example of a model toy, but this does not limit the scope of the invention. The invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and decorations. The head 101 is connected to the torso 102. On the torso 102, a right arm 103b and a left arm 103a are connected to the sides using spherical connecting members, and a right leg 104b and a left leg 104a are connected to the lower part. That is, the left arm 103a and the right arm 103b are assembled relative to the torso 102 in a manner that allows them to rotate in all directions within the space constraints of other accessories. This structure is called a ball joint.

[0027] Additionally, as shown in the figure, a decorative part 105 is fitted to the right arm portion 103b. Although not shown, other accessories such as decorative parts can also be fitted to the left arm portion 103a by connecting it to the hole provided in the shoulder portion. Furthermore, details regarding the hole provided in the shoulder portion will be described later.

[0028] <Arm assembly structure>

[0029] Next, refer to Figure 2 The assembly structure of the arm 103 of the model toy 100 of this embodiment will be described. Figure 2 (a) indicates the case where the left arm 103a is removed from the model toy 100. Figure 2 (b) represents an exploded perspective view of the left arm. The structure of the left arm 103a will be described here. Furthermore, the structure of the right arm 103b is the same as that of the left arm 103a, therefore its description is omitted.

[0030] like Figure 2 As shown in (a), the left arm 103a is connected to the torso 102 via a spherical second connecting portion of the movable member 201. Additionally, a first connecting portion shaped like the letter C is provided at one end of the movable member 201, and this connecting portion is connected to the left arm 103a. Therefore, the left arm 103a is connected to the torso 102 via the second connecting portion in a manner that allows it to rotate in all directions within the limitations imposed by other members, and via the first connecting portion in a manner that allows it to rotate in the up-and-down directions.

[0031] like Figure 2As shown in (b), the left arm portion 103a includes a shoulder joint, an upper arm portion 203, and a forearm portion 204. The shoulder joint is configured to include a movable member 201 and shoulder fittings 202a, 202b, and 202c. As an assembly structure for these fittings, shoulder fittings 202a and 202b are assembled, and shoulder fitting 202c is assembled relative to them. A rod member formed at the lower part of the assembled shoulder fitting 202 is inserted into the upper arm portion 203, and then the upper arm portion 203 is inserted into the forearm portion 204.

[0032] Furthermore, the first connecting portion of the movable member 201 is inserted into the shoulder fitting 202 to complete the assembly of the left arm 103a. The left arm 103a is connected to the torso 102 in a manner that allows it to rotate relative to the torso 102 by inserting the second connecting portion of the movable member into the member of the torso 102. Alternatively, as the assembly sequence of the movable member 201, it can be assembled to the torso 102 first, and then assembled relative to the left arm 103a, including the shoulder fitting 202.

[0033] <Structure of movable components>

[0034] Next, refer to Figure 3 The detailed structure of the movable member 201 in this embodiment will be described. Figure 3 (a) represents a three-dimensional view of the movable component 201. Figure 3 (b) represents a side view of the movable member 201.

[0035] The movable member 201 includes a first connecting portion 301, a rod portion 302, a second connecting portion 303, and a track portion 305. The first connecting portion 301 is formed in the shape of the letter C at one end of the rod portion 302 and is connected to the shaft 401 so as to be rotatable relative to the shaft 401 of the shoulder accessory (receiving portion) 202 described later. On the other hand, the second connecting portion 303 is formed in the shape of a ball at the other end of the rod portion 302 and is connected to the accessory of the torso 102 so as to be rotatable relative to the accessory of the torso 102. Furthermore, there is no intention to limit the second connecting portion 303 to a ball-shaped connecting portion; it can also be a connecting portion of other shapes. For example, the second connecting portion can also be formed in the same shape as the first connecting portion 301, in the shape of the letter C, or it can be formed in the shape of a ring or other shapes.

[0036] Furthermore, the first connecting portion 301 has two end edges 304a and 304b located at the front end of the letter C shape. The end edges 304a and 304b are located near the opening of the letter C shape. The distance between the two end edges is narrower than the width of the shaft 401 of the shoulder fitting 202. In addition, as shown in the dashed area of ​​reference numeral 307, a convex overhang is formed on the inner side of the end edges 304a and 304b. That is, it functions as an overhang when connecting the movable member 201 relative to the shaft 401, preventing it from falling off the shoulder fitting 202. Therefore, at least the first connecting portion 301 in the movable member 201 is formed using an elastic member that flexes according to the pressure generated during rotation when connected relative to the shaft 401.

[0037] Furthermore, a track portion 305 is formed on the outer side of the first connecting portion 301, partially along the shape of the letter C. In this embodiment, the form of the track portion 305 located on the outer side of the lower edge portion 304b of the letter C shape is described, but this is not intended to limit the invention. For example, it may be formed on the outer side of the edge portion 304a instead. The track portion 305 is formed as a groove to accommodate the insertion portion 402 formed on the shoulder accessory 202a, preventing the first connecting portion 301 from falling off the shoulder accessory 202. Furthermore, the track portion 305 is an example of a sliding portion provided along the rotation direction of the first connecting portion 301, and its shape is not particularly limited as long as the insertion portion 402 can be held in a sliding position. By inserting the insertion portion 402 deep into the track portion 305, a structure is formed that makes it difficult for the movable member 201 to fall off the shoulder accessory 202. In addition, the track portion 305 and the insertion portion 402 may also be provided in opposite directions. That is, the track part 305 can be provided on the shoulder accessory 202, and the insertion part 402 can be provided on the movable member 201.

[0038] Furthermore, a protrusion 306 is formed on the inner wall of the first connecting portion 301. The protrusion 306 is embedded in the recess 406 formed on the shaft 401. By embedding the protrusion 306 into the recess 406 in this way, it is possible to prevent the movable member 201 from falling out in the front-rear direction. In addition, the recess 406 is formed along a partial circumference of the outer peripheral surface of the shaft 401, and the protrusion 306 is formed correspondingly to its shape. Therefore, when the movable member 201 rotates relative to the shaft 401, the protrusion 306 rotates along the recess 406, and thus does not hinder the rotation of the movable member 201.

[0039] <Structure of the connecting part>

[0040] Next, refer to Figure 4 The detailed structure of the shoulder fitting 202, which serves as the receiving part in this embodiment, will be described. Figure 4 (a) represents a side view of shoulder fitting 202a. Figure 4(b) represents the side view of shoulder accessory 202b. Figure 4 (c) represents a three-dimensional view of shoulder accessory 202.

[0041] like Figure 4 As shown in (a), the shoulder fitting 202a on the back side is formed to include a shaft portion 401a and an insertion portion 402. Additionally, as... Figure 4 As shown in (b), the shoulder fitting 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 torso 102 is rotatably embedded in the upper arm portion 203.

[0042] The insertion part 402 is a component that is inserted into the track part 305. Here, an example is described where the insertion part 402 is formed only on one side of the shoulder fitting 202a. However, the insertion part 402 can also be provided on the shoulder fitting 202b, and the track part 305 can be provided on the side of the movable member 201 near the shoulder fitting 202b, with the insertion part 402 and the track part 305 formed on both sides. This improves the function of preventing the movable member 201 from detaching from the shoulder fitting 202. In this case, the width of the track part 305 formed on the movable member 201 also needs to be specified to accommodate the insertion parts provided on both sides.

[0043] Figure 4 (c) indicates the assembled state of shoulder fittings 202a, 202b, and 202c. When assembling shoulder fittings 202a and 202b, shaft portions 401a and 401b are connected to form shaft 401. Shaft 401 is formed in a cylindrical shape, with a recess 406 formed in a portion thereof. As described above, the protrusion 306 formed on the movable member 201 is rotatably inserted into the recess 406. Figure 4 As shown in (c), the insertion portion 402 is provided on one side (back side) of the shoulder fitting 202. However, as described above, the insertion portion 402 may also be provided on the other side (front side), or on both sides. Furthermore, in this embodiment, the shaft portions 401a and 401b constituting the shaft 401 are shafts of different diameters, but they may also be shafts of the same diameter. However, when the insertion portion 402 is provided only on one side of the shoulder fitting 202, as... Figure 4 As shown in (c), by making the diameter of the shaft portion 401a adjacent to the insertion portion 402 smaller than the diameter of the shaft portion 401b, space saving can be achieved.

[0044] Additionally, as indicated by reference numerals 407a and 407b in the accompanying drawings, holes for connecting other fittings are formed on the outer side of the shaft 401. Holes 407a and 407b are formed from the outer side of the shoulder fittings 202a and 202b toward the interior of the shaft 401, and are capable of accommodating the rod portion of other fittings. Furthermore, while holes 407a and 407b are provided corresponding to the shaft 401 in this embodiment, this does not limit the scope of the invention; for example, they could be provided at other locations on the shoulder fittings 202.

[0045] Assembly Steps

[0046] Next, refer to Figure 5 The steps for assembling the movable member 201 of this embodiment relative to the shoulder fitting 202 are described.

[0047] like Figure 5 As shown in (a), the movable member 201 is assembled in the direction of the arrow relative to the assembled shoulder accessory 202. At this time, the first connecting part 301 and the track part 305, which are shaped like the letter C, are adjusted and assembled in such a way that they are respectively inserted into the shaft 401 and the insertion part 402. Here, the insertion part 402 is inserted from an obliquely upward direction, corresponding to its shape.

[0048] Figure 5 (b) represents a sectional view of the shoulder joint. For example... Figure 5 As shown in (b), the movable member 201 is connected to the shoulder fitting 202 in a manner that allows it to rotate about the axis 401 in the direction of the dashed arrow. Furthermore, by rotating the movable member 201 relative to the shoulder fitting 202, the insertion portion 402 is driven deep into the track portion 305, thereby improving the function of preventing the movable member 201 from falling off. In other words, although there is a possibility of the movable member 201 falling off at the position where it is connected to the shoulder fitting 202, the possibility of falling off is reduced by rotating the insertion portion 402 from that position to drive it deep into the track portion 305.

[0049] <Arm Assembly>

[0050] Reference Figure 6 and Figure 7 The assembly of the left arm 103a to the torso 102 will be explained. Figure 6 and Figure 7 The upper body of the model toy 100 is shown, with only the shoulder joint section shown in cross-section to clarify the internal structure. Here, the process is described in the order of first assembling the movable member 201 relative to the torso 102, and then assembling the arm 103.

[0051] like Figure 6As shown in (a), the spherical second connecting portion 303 of the movable member 201 is connected to the torso 102 in a manner that allows it to rotate relative to the torso 102. Then, the shaft 401 and insertion portion 402 of the left arm portion 103a are inserted and connected from an obliquely upward position, aligned with the first connecting portion 301 and the track portion 305 of the movable member 201. That is, as... Figure 6 As shown in (a), the left arm 103a is assembled in a state where it is raised above the model toy 100.

[0052] Then, as Figure 6 As shown in (b), the left arm 103a rotates downwards (in the direction of the dashed arrow) about axis 401, moving towards its normal position. Furthermore, after the left arm 103a is fitted to the movable member 201, this movement occurs naturally due to its weight. On the other hand, the connection between the movable member 201 and the shoulder fitting 202 can be configured such that the outer periphery of axis 401 is adjusted to be larger to improve the strength of the fit and prevent the left arm 103a from naturally moving towards its normal position due to its weight. In this case, a predetermined force needs to be applied to move the left arm 103a to its normal position.

[0053] Figure 7 This indicates the left arm portion 103a after being assembled to the torso 102 and moved to its normal position. The dashed area 702 shows an enlarged view of the dashed area 701. As shown, when the left arm portion 103a moves to its normal position, the insertion part 402 enters deep into the track part 305. In this state, when force is applied in the direction of the solid arrow, in the portion shown in the dashed area 703, the insertion part 402 engages with the inner wall of the track part 305, which forms the outer wall of the first connecting part 301, thus preventing the left arm portion 103a from being pulled out.

[0054] As explained above, the movable structure of this embodiment includes: a receiving portion having a cylindrical shaft; and a movable member having a first connecting portion connected to the shaft in a manner rotatable relative to the shaft, wherein a track portion partially provided along the outer shape of the first connecting portion is formed in the receiving portion or the movable member. Thus, according to this embodiment, a new structure can be provided for movable structures and model toys. More specifically, in movable structures and model toys, assembly can be easily achieved, and the detachment (pull-out) of parts can be significantly reduced.

[0055] <Variation Example>

[0056] This invention is not limited to the embodiments described above, but can be modified and altered in various ways within the scope of the invention's intent. For example, the shape of the model toy is not particularly limited, and includes a wide variety of shapes such as people, animals, robots, insects, and dinosaurs.

[0057] Furthermore, according to the above embodiment, an example in which the track portion 305 is formed on the outer side of the end edge portion 304b of the movable member 201 has been described. However, the track portion may also be formed alternatively or additionally on the outer side of the end edge portion 304a, or it may be formed on the shoulder fitting 202 side. When the track portion is provided on the shoulder fitting 202 side, an insertion portion is formed on the movable member side.
