Description

The present invention relates to a model toy and a movable structure.

Doll type toys (model toys) are required to realize natural movements and a variety of poses. Therefore, in order to realize movements and poses similar to those of humans and animals, doll-type toys include various joints and movable parts. Patent Document 1 proposes an assembly system in which a ball is rotatably connected to a socket made of a petal member.

Special Publication No. 11-501556

In the above-mentioned conventional technology, the ball and the socket are fitted and connected, and the ball is elastically locked to the socket. However, these shaft members and receivers in the movable structure may fall off due to the attractive force generated by the movable structure. Therefore, in order to prevent these members from falling off, it is conceivable to form the recess on the receiving side narrower to increase the fitting force. On the other hand, increasing the fitting force may cause problems such as difficulty in inserting the parts during assembly.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the claimed invention, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the plurality of features described in the embodiments may be arbitrarily combined. In addition, the same or similar configurations are given the same reference numerals, and duplicate explanations will be omitted.

<Assembly configuration of movable structure>
First, with reference to FIG. 1, an example of the assembly configuration of the movable structure 100 according to the present embodiment will be described. FIG. 1 shows a perspective view of a movable structure 100. Note that the up and down, left and right, and front and back arrows indicate the orientation of the movable structure or doll-shaped toy in the figure, and the same applies to other figures.

As shown in FIG. 1(a), the movable structure 100 includes a movable member 101 and a receiving portion 102. Furthermore, the movable structure 100 is incorporated into a doll-type toy (not shown) and functions as a movable structure such as a joint. For example, the movable structure according to this embodiment can be applied to joints such as ankle joints, neck joints, shoulder joints, hip joints, elbow joints, and knee joints. The movable member 101 is inserted into and connected to the receiving portion 102 in the direction of the arrow.

FIG. 1(b) shows a state in which the movable member 101 is inserted into the receiving portion 102 from a predetermined direction and connected. Thereafter, they are fitted in the direction of the arrow and are rotatably fitted. The detailed mechanism of fitting will be described later. FIG. 1(c) shows a state in which the movable member 101 is rotatably fitted to the receiving portion 102.

As described above, according to the present embodiment, the movable member 101 is connected to the receiving part 102 at a position different from the normal position (FIG. 1(c)) when the movable member 101 is assembled to the receiving part 102. Thereafter, by rotating the movable member 101 relative to the receiving portion 102, it can be rotated to the normal position.

<Structure of the receiving part>
Next, the detailed configuration of the receiving portion 102 according to this embodiment will be described with reference to FIG. 2. FIG. 2(a) shows a perspective view of the receiving part 102. FIG. 2(b) shows a plan cross section of the receiving portion 102.

As shown in FIG. 2A, the receiving portion 102 is formed to include a base portion 201, clamping portions 202a and 202b, and a shaft 203. The shaft 203 is formed in a cylindrical shape, and is formed so that its upper and lower sides are sandwiched between the clamping parts 202a and 202b extending from the base 201. A recess 204 is formed along the circumference in a part of the outer peripheral surface of the shaft 203 . Moreover, a part of the cylindrical shaft 203 is cut (cut), and part of the side surface (curved surface) of the cylinder has flat surfaces 208a and 208b. In this embodiment, the term "cut" means cutting out or scraping off a part of a part included in a model toy or the like. Note that in the manufacturing process of the shaft 203, it is not necessary to actually cut the shaft 203, and the shaft 203 may be molded into a shape having a flat surface with both sides cut from the beginning. Further, a wall portion 210 is formed on the base portion 201, and the wall portion 210 and the flat surfaces 208a and 208b are arranged at positions substantially parallel to each other. In this embodiment, an example will be described in which both sides of the cylindrical shaft 203 are cut, but the invention is not limited to this, and the case may be such that only one side is cut.

FIG. 2(b) shows a cross section taken along the line XX' in FIG. 2(a) and viewed from the direction of the arrow. As shown in FIG. 2(b), both side surfaces of the shaft 203 that come into contact with a portion of the movable member 101 when the movable member 101 is connected are cut. The cut portions of the shaft 203 are shown by hatching. 205a and 205b indicate portions of the shaft 203 that are cut on each side. The portions 205a and 205b indicate the amount of cut or the width of the cut, and on each side, the diameter 207 of the cylindrical circle perpendicular to the insertion direction of the movable member 101 into the shaft 203 (indicated by the solid arrow in the figure) is the diameter 207 of the cylindrical shape. It has widths 206a and 206b of 0.2 mm from the point where it intersects with the outer periphery.

Such a cut allows the movable member 101 to be easily inserted in a predetermined direction with respect to the shaft 203. In other words, the amount of crossing over when inserting the movable member 101 into the shaft 203 can be reduced. On the other hand, due to such a cut, the force for fitting the movable member 101 and the receiving portion 102 together becomes weaker compared to the case where the cylindrical shape is not cut. However, according to the present embodiment, when the movable member 101 is rotated to the normal position with respect to the shaft 203, since both sides are not cut, the above-mentioned amount of crossing increases, and the fitting force is increased. be able to.

Further, by cutting the region 205b of the shaft 203, the strength of the mold for manufacturing the part corresponding to the receiving portion 102 can be increased. In the manufacturing process of the receiving part 102, the receiving part 102 is molded in a predetermined mold, and a part of the mold is formed so as to fit into the space between the base part 201 and the shaft 203. In that case, since the side surface of the shaft 203 is cut, the distance between the part and the base 201 can be increased, and the width of the part of the mold formed between them can be increased. can do. Therefore, the strength of the mold can be increased in this portion. In the manufacturing process, it is necessary to remove the molded part from the mold after the part is molded, which causes friction and wears the mold, but it reduces mold breakage because it can be formed over a wider area. be able to.

Further, according to the present embodiment, the holding parts 202a and 202b are formed to sandwich the shaft 203 from above and below as supports for the above-mentioned fitting, and are formed wider than the width of the shaft 203. As a result, when the movable member 101 is connected to the shaft 203, the clamping parts 202a and 202b come into contact with the upper and lower surfaces of the movable member 101 when inserted or rotated to the normal position, and the movable member 101 and the receiving part 102 can be supported. With such a mechanism, according to the present embodiment, it is possible to prevent the movable member 101 from falling off the receiving part 102.

<Configuration of movable members>
Next, the detailed configuration of the movable member 101 according to this embodiment will be described with reference to FIG. 3. FIG. 3(a) shows a perspective view of the movable member 101. FIG. 3(b) shows a plan view of the movable member 101.

The movable member 101 includes a first connecting portion 303, a rod portion 302, and a second connecting portion 301. The first connecting portion 303 is formed in a C-shape at one end of the rod portion 302 and is rotatably connected to the shaft 203 of the receiving portion 102 . On the other hand, the second connecting part 301 is formed in a spherical shape at the other end of the rod part 302, and is rotatably connected to other parts. Note that there is no intention to limit the second connecting portion 301 to a spherical connecting portion, and the second connecting portion 301 may be a connecting portion having another shape. For example, the second connecting portion may be formed in a C-shape like the first connecting portion 303, or may be formed in a ring shape or other shapes.

Further, the first connecting portion 303 includes two edge portions 303a and 303b located at the tip of the C-shape. The edge portions 303a and 303b are located near the C-shaped opening. As shown in FIG. 3(b), the distance d1 between the two end edges is narrower than the width d2 in the direction in which both side surfaces of the shaft 203 are cut. In other words, it functions as a crossing part when connecting the movable member 101 to the shaft 203, and prevents it from falling off from the receiving part 102. Therefore, at least the first connecting portion 303 of the movable member 101 is formed using an elastic member so as to bend in response to the pressure generated when connected to the shaft 203 or when rotated.

Furthermore, a convex portion 304 is formed on the inner wall of the first connecting portion 303 . The protrusion 304 is fitted into the recess 204 formed in the shaft 203. By fitting the convex portion 304 into the concave portion 204 in this manner, it is possible to prevent the movable member 101 from falling off in the vertical direction. Note that the recess 204 is formed along a part of the circumference of the outer circumferential surface of the shaft 203, and the protrusion 304 is formed to match the shape. Therefore, since the convex portion 304 rotates along the concave portion 204 when the movable member 101 rotates about the shaft 203, the rotation of the movable member 101 is not inhibited.

<Assembly procedure>
Next, with reference to FIG. 4, a procedure for assembling the movable member 101 according to this embodiment to the receiving portion 102 will be described.

FIG. 4(a) shows a state in which the movable member 101 is inserted into the receiving portion 102 at the insertion position. At the time of insertion (connection), the end edges 303a and 303b of the first connecting portion 303 each expand outward to receive and grip the shaft 203 inside the C-shaped first connecting portion 303. At this time, since both sides of the shaft 203 are cut, it is possible to suppress the outward expansion of each of the end edges 303a and 303b, and the movable member 101 can be inserted more easily than when the ends are not cut. Can be done. On the other hand, in this state, as shown in dotted line areas 401a and 401b, both cut sides of the shaft 203 are not in contact with the inner wall of the first connecting portion 303. Therefore, there is a possibility that the fitting force will be weaker compared to the case where the cut is not made. Note that, as described using FIG. 2, according to the present embodiment, for example, the holding portion 102 is provided with the holding portions 202a and 202b, and the holding portions 202a and 202b abut against the movable member 101 and are movable. Fitting of the member 101 and the receiving part 102 can be supported.

FIG. 4(b) shows a state in which the movable member 101 is rotated to the normal position. When the movable member 101 is rotated 90 degrees in the direction of the arrow from the inserted state shown in FIG. 4(a), it becomes the state shown in FIG. 4(b). In other words, the movable member 101 can rotate based on a normal position rotated by 90 degrees around the shaft 203. In this state, both uncut side surfaces of the shaft 203 abut against the inner wall of the first connecting portion 303 . Therefore, in the direction in which the movable member 101 is pulled out, the amount of riding over increases, and falling off from the receiving portion 102 can be further reduced. On the other hand, as shown in the dotted line area 402, the cut surfaces face each other at the innermost part of the first connecting portion 303, forming a space. For example, if the shaft 203 is not cut, the surface of the shaft 203 will come into contact with the innermost part of the first connecting part 303 and press that part. Such pressure may cause the area to turn white. However, according to the present embodiment, since a space is formed in the portion, such whitening can be prevented.

<Structure of the foot>
An example of a doll-shaped toy incorporating the movable structure according to the present embodiment will be described below with reference to FIGS. 5 and 6. Here, an example will be described in which the movable structure according to the present embodiment is incorporated into the foot of a doll-type toy (as part of the ankle joint). Note that the example in which the present movable structure is applied as a part of the ankle joint is one example and is not intended to limit the present invention. For example, the present movable structure can be applied to movable parts such as other joints, such as neck joints, shoulder joints, hip joints, elbow joints, knee joints, etc.

5(a) shows a front view of the foot part 500, and FIG. 5(b) shows a side view of the foot part 500. The foot portion 500 includes parts 501, 503, 504 and a shaft portion 502. In the foot portion 500, a cylindrical rod portion formed at the upper portion of the shaft portion 502 is further connected to a leg portion (not shown) of the doll-type toy. Parts 501, 503, and 504 are each rotatably connected to shaft portion 502. An example in which the movable structure according to the present invention is connected to a first part 501 and a second part 504 will be described below.

FIG. 6(a) shows a side sectional view of the foot portion 500. The parts 501 and 504 and the shaft portion 502 are connected by a connecting member 601. The connecting member 601 is a part corresponding to the movable member 101, and is rotatably connected to a shaft 602 of a receiving portion assembled to the part 501. The connecting portion 601 includes a first connecting portion 601a and a second connecting portion 601b. The first connecting portion 601a is formed in a C-shape and is rotatably connected to the shaft 602. This allows the part 501 to rotate around the shaft 602 as shown at 611. On the other hand, the second connecting portion 601 is formed in a spherical shape, and as shown at 612, the part 504 is rotatably connected thereto.

As described above, the movable structure according to the present embodiment includes a receiving portion having a cylindrical shaft, and a movable member having at one end a first connecting portion rotatably connected to the shaft. The shaft of the receiving part has both sides cut so that a part of the first connecting part can come into contact with the first connecting part when connecting the first connecting part. Thereby, in the movable structure, members can be easily assembled, and falling off can be reduced. In this way, according to this embodiment, a novel mechanism can be provided in the movable structure.

In addition, although an example of a doll-shaped toy has been explained as a model toy, the shape of the doll-shaped toy (doll body) is not particularly limited, and can be various shapes such as humans, animals, robots, insects, dinosaurs, virtual life forms, etc. This includes shapes such as Moreover, the shape of the model toy is not particularly limited as long as it includes a movable part.
