Description

The present invention relates to model toys and movable structures.

To realize movements and poses similar to those of humans and animals, doll toys (model toys) include various joints and movable parts. These mechanisms allow for a variety of poses. However, providing a doll toy with the same number of joints as a human or other animal would require a large number of parts, and even in an elaborate doll toy, the number is limited and it is difficult to achieve this. Therefore, in order to realize the movements and poses described above, it is important to expand the range of motion of the joints and the parts connected to them while configuring them with fewer joints and parts. By expanding the range of motion, it is possible to perform movements with a higher degree of freedom and a variety of poses. Patent Document 1 proposes a quadruped animal doll with a joint structure that allows for realistic movements similar to those of real animals.

JP 2010-17264 A

To achieve natural movements like those of human limbs, it is desirable for them to be able to rotate in various directions. However, in model toys, elbow joints, knee joints, etc. generally only rotate in specific directions. In such model toys, it is difficult to achieve the bending and twisting movements that occur in human limbs.

The present invention provides, for example, a new mechanism for moving a model toy.

The present invention is a model toy comprising: a base part having a first connecting portion and a second connecting portion and a rotation axis; a first part rotatably connected to the base part via the first connecting portion in a first direction; and a second part connected to the base part via the second connecting portion and rotatable in a second direction different from the first direction around the rotation axis of the base part.
The present invention also provides, for example, a model toy comprising a base part having a first connecting portion and a second connecting portion and a rotation axis, a first part rotatably connected to the base part via the first connecting portion in a first direction, and a second part connected to the base part via the second connecting portion and rotatable in a second direction different from the first direction around the rotation axis of the base part, wherein the first part includes first and second parts, which are connected so as to sandwich the base part, and a third connecting portion formed on one of the first and second parts is inserted into the first connecting portion.

The present invention is also characterized in that, for example, a movable structure of a model toy includes a base part having a first connecting part and a second connecting part and a rotation axis, a first part rotatably connected to the base part via the first connecting part, and a second part connected to the base part via the second connecting part and rotatable in a second direction different from the first direction around the rotation axis of the base part.
The present invention also provides, for example, a movable structure of a model toy, comprising a base part having a first connecting portion and a second connecting portion and a rotation axis, a first part rotatably connected to the base part via the first connecting portion in a first direction, and a second part connected to the base part via the second connecting portion and rotatable in a second direction different from the first direction around the rotation axis of the base part, wherein the first part includes first and second parts, which are connected so as to sandwich the base part, and a third connecting portion formed on one of the first and second parts is inserted into the first connecting portion.

The present invention can provide, for example, a new mechanism for moving a model toy.

The following embodiments are described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be combined in any combination. In addition, the same reference numbers are used for the same or similar configurations, and duplicate descriptions are omitted.

<Appearance of the left leg of the model toy>
First, the left leg incorporated in the model toy according to this embodiment will be described with reference to Fig. 1. Fig. 1(a) shows the front exterior of the left leg 100 of the model toy, and Fig. 1(b) shows the side exterior of the left leg 100 of the model toy. Note that the x, y, and z arrows indicate the upward, left, and forward directions of the model toy, respectively, and this also applies to the other drawings.

The left leg 100 comprises an upper leg 101, a knee joint 102, a lower leg 103, and a foot 104. In this embodiment, a humanoid robot is used as an example of a model toy, but this is not intended to limit the invention, and the invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and accessories. The right leg is not shown, but is formed symmetrically to the left leg and has a similar configuration, so a description of it will be omitted.

In addition, in this embodiment, an example of applying the present invention to the legs of a model toy is described, but a similar configuration can also be applied to the arms, neck, waist, etc. of a model toy. In particular, in the arms, the upper arm, elbow joint, forearm, and hand can be realized as a configuration corresponding to the upper leg, knee joint, lower leg, and foot of the legs, respectively.

The upper leg portion 101 is rotatably connected to the knee joint portion 102. The lower leg portion 103 is further rotatably connected to the knee joint portion 102. Furthermore, the foot portion 104 is connected to the lower part of the lower leg portion 103 by a spherical connecting portion. The knee joint portion 102 according to this embodiment rotatably connects the upper leg portion 101, which is a first part, and the lower leg portion 103, which is a second part, in the vertical direction of the model toy, which is a first direction. Furthermore, the knee joint portion 102 connects the upper leg portion 101 and the lower leg portion 103 in the horizontal direction of the model toy, which is a second direction different from the first direction. Details of these rotation mechanisms will be described later.

<Structure around the knee joint>
Next, the configuration around the knee joint of the left leg 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2(a) shows a side view of the left leg 100 disassembled into three parts. Fig. 2(b) shows an exploded configuration of a portion of the left leg 100. Here, the configuration of the left leg 100 will be described, but the configuration of the right leg (not shown) will not be described since it has the same configuration as the left leg.

Reference numeral 200 denotes the area surrounding the knee joint of the left leg 100. As shown in FIG. 2(b), the area surrounding the knee joint 200 is made up of parts 201 to 211. Part 201 is the base part of the knee joint, and parts 202a and 202b, which form part of the upper leg, are connected to it so as to sandwich it from both sides. Furthermore, parts 203a and 203b, which form part of the lower leg, are connected to it so as to sandwich it from both sides.

Part 211, which forms part of the upper leg 101, is rotatably connected to the top of parts 202a and 202b. Part 211 is further connected to other parts of the upper leg 101. Part 210 is rotatably connected to the bottom of parts 203a and 203b to form the ankle. Foot 104 is further rotatably connected to part 210. Parts 206 to 209 are exterior parts for the legs.

<Components>
Next, each part constituting a rotation mechanism in the knee joint of the left leg 100 according to this embodiment will be described with reference to Fig. 3. Fig. 3 shows an exploded perspective view of each part.

Part 201, which is the base part, is composed of a rod-shaped rotating shaft 311, a ring-shaped connecting part 312, and a protrusion 313 formed on the outer periphery of the rotating shaft 311. The protrusion 313 is fitted into a recess 331a formed in part 203a. The recess 331a is formed to be larger than the protrusion 313, and does not restrict the rotation of part 201.

Part 203b also has a recess (not shown), and when part 201 is sandwiched between parts 203a and 203b, protrusion 313 of part 201 is rotatably fitted into the recess. Part 201 rotates in the horizontal direction (second direction) of the model toy around rotation axis 311.

The cylindrical connecting portion 321a of part 202a is inserted into the connecting portion 312 of part 201. The inserted connecting portion 321a then passes through the ring-shaped connecting portion 312 and is connected to part 202b on the opposite side. In this way, parts 202a and 202b are rotatably connected so as to sandwich part 201.

Part 202a is formed with cylindrical connecting portion 322a, similar to connecting portion 321a. Connecting portion 322a is inserted into and passes through ring-shaped connecting portion 341 provided on part 211, and is connected to part 202b on the opposite side. In other words, parts 202a and 202b are rotatably connected to part 201 and part 211 in a similar manner so as to sandwich them therebetween.

The rotation mechanism with the connecting parts 321a, 322a as the rotation axis can rotate the parts 201, 211 connected to the connecting parts 321a, 322a in the vertical direction (first direction) of the model toy. In other words, these rotation mechanisms realize the rotation of the legs at a normal knee joint by a two-stage rotation movement, and can expand the range of motion.

In addition, parts 202a, 202b, and 211 connected to connecting part 312 also rotate in conjunction with the rotation of part 201 around rotation axis 311. Therefore, the knee joint according to this embodiment can realize rotational movements in two directions: a first direction (vertical direction) of the model toy, and a second direction (horizontal direction) different from the first direction. The second direction is, for example, a direction that differs by approximately 90 degrees from the first direction. This makes it possible to express the "flexibility" of the legs, for example, and to express the "flexibility of the legs" with a flair in movements such as high kicks. Details will be described later using FIG. 5.

The present invention is not limited to the above rotation direction, and the rotation direction can be determined in any direction depending on the position where the rotation mechanism is employed. Also, according to this embodiment, the second direction is defined as a direction that is approximately 90 degrees different from the first direction in order to realize the "bending" and "twisting" movements in the model toy, but the present invention does not limit these angles, and the angle can be any angle depending on the movement to be realized.

<Rotational movement>
Next, various rotational movements of the left leg 100 of the model toy according to this embodiment will be described with reference to Figures 4 and 5. Figures 4(a) and 4(b) show the rotational movement of the leg in a first direction (vertical direction). Figure 4(c) shows the rotational movement of the leg in a second direction (horizontal direction). Figure 5 explains posing using multiple rotational movements of the left leg. Note that although parts 202 and 203 in Figures 4(a) to 4(c) are each composed of two parts, only parts 202a and 203a on the right side are shown here for ease of explanation.

As shown in FIG. 4(a), part 211 can rotate in the direction indicated by the arrow (first direction) around rotation axis 401. Rotation axis 401 is formed by inserting cylindrical connecting portion 322a of part 202a into ring-shaped connecting portion 341 of part 211. In response to this rotational movement, the parts of upper leg 101 connected to part 201 can rotate in the vertical direction (up and down direction) of the model toy.

As shown in FIG. 4(b), part 202a can rotate in the direction indicated by the arrow (first direction) around rotation axis 402. Rotation axis 402 is formed by inserting cylindrical connecting portion 321a of part 202a into ring-shaped connecting portion 312 of part 201. In response to this rotational motion, the parts of upper leg 101 connected to part 201 can rotate in the vertical direction (up and down direction) of the model toy. Therefore, it rotates in the same direction as the rotational motion shown in FIG. 4(a), and the range of motion of the knee joint of the model toy can be expanded. As shown in FIG. 4(b), it can be rotated to a position where the leg is folded at the knee joint.

As shown in FIG. 4(c), part 201 can rotate in the direction indicated by the arrow (second direction) around rod-shaped rotation axis 311. This rotation can be performed within the range sandwiched between parts 203a and 203b. This rotation also causes the parts of upper leg 101 connected to part 201 to rotate in conjunction with it.

In response to this rotational movement, part 201 can rotate in the horizontal direction (left and right direction) of the model toy relative to connected parts 203a and 203b. In this way, in the model toy according to this embodiment, the knee joint can move in two rotational directions, a first direction and a second direction different from the first direction, allowing for more natural poses and movements.

Figure 5(a) shows the left leg 100 before the rotational motion. Figure 5(b) shows the state in which the lower leg 103 and foot 104 have been rotated in the direction of the arrow around the rotation axis 311 from the state in Figure 5(a). In this way, in addition to the bending and stretching of the leg caused by the normal rotational motion of the knee joint, the model toy according to this embodiment can perform a rotational motion in a direction different from the bending and stretching motion. As a result, for example, when performing a pose such as a high kick with the model toy, the bending of the leg can be reproduced by performing a twisting motion as shown in Figure 5(b), allowing for a more realistic pose.

As described above, the model toy according to this embodiment includes a base part having a first connecting part, a second connecting part, and a rotation axis, a first part rotatably connected to the base part via the first connecting part in a first direction, and a second part connected to the base part via the second connecting part and rotatable in a second direction different from the first direction around the rotation axis of the base part. In this way, according to this embodiment, a joint mechanism that performs rotational movements in two directions can be realized in the joint structure provided in the model toy. This allows the legs, arms, etc. to perform "bending" and "twisting" movements, allowing for extravagant movements. In this way, according to this embodiment, for example, a new mechanism for a movable mechanism in a model toy can be provided.

The present invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the gist of the invention. For example, the shape of the model toy is not particularly limited, and may include various shapes such as people, animals, robots, insects, and dinosaurs.
