Description

Technical Field

[0001] This invention relates to model toys and joint structures. Background Technology

[0002] To achieve movements and postures similar to those of humans and animals, humanoid toys (model toys) include various joints and movable parts. These mechanisms allow for a wide variety of poses. However, setting the same number of joints as humans requires many components, and even for intricately designed humanoid toys, the number of joints is limited, making implementation difficult. Therefore, to achieve the aforementioned movements and postures, it is important to construct the toy with fewer joints and components, and to expand the movable area of ​​the joints and their connected parts. By expanding the movable area, a higher degree of freedom of movement and a wider range of poses can be achieved. Patent Document 1 proposes a quadrupedal humanoid with a joint structure capable of performing realistic movements similar to those of a real animal.

[0006] The problem the invention aims to solve

[0007] To achieve natural movements like those of human limbs, the desired capability is the ability to rotate in all directions. On the other hand, by incorporating shoulder, hip, and lumbar joints internally, similar to those in humans, natural movement of the components connected to these joints can be achieved; however, this range of motion is limited by adjacent components. Therefore, to expand the range of motion, it is important to ensure sufficient space between adjacent components.

[0009] Solution for solving the problem

[0010] The present invention is, for example, a model toy, characterized in that the model toy comprises: a first component having a recess; and a second component having a cylindrical shaft connected to the recess of the first component in a manner rotatable relative to the recess of the first component, the second component being movable between a first region and a second region formed in the recess, and performing a rotational action about the cylindrical shaft as a center in each region.

[0011] Furthermore, the present invention includes, for example, a joint structure characterized in that the joint structure comprises: a first component having a recess; and a second component having a cylindrical shaft connected to the recess of the first component in a manner rotatable relative to the recess of the first component, the second component being movable between a first region and a second region formed in the recess, wherein rotational action is performed in each region about the cylindrical shaft as a center.

[0025] 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 not all combinations of features described in the embodiments are essential to the invention. Two or more features from the plurality of features described in the embodiments can be combined arbitrarily. Additionally, the same or identical structures are labeled with the same reference numerals, and repeated descriptions are omitted.

[0026] <First Embodiment>

[0027] <Appearance of model toys>

[0028] The first embodiment of the present invention will be described below. First, refer to... Figure 1A and Figure 1B An example of the appearance configuration of the model toy 100 of this embodiment will be described. Figure 1A This shows the front view of model toy 100. Figure 1B The figures show (a) an exploded perspective view of the model toy 100 and (b) an exploded perspective view of its upper body. Additionally, the arrows pointing up / down, left / right, and forward / backward indicate the orientation of the model toy in the figures, and the same applies to the other figures.

[0029] The model toy (humanoid figure) 100 includes a head 101, chest 102, arms 103a and 103b, abdomen 104, clothing 105, and legs 106a and 106b. The model toy 100 is an articulated model toy, such as a posable human figure, where each part can move within the limited area created by the relationship between it and other components. The head 101 is connected to the chest 102 by a spherical connecting member (hereinafter also referred to as a ball joint). The chest 102 is also connected to the arms 103, including the right arm 103a and the left arm 103b, by a spherical connecting member, and the abdomen 104 is connected at the lower part. The detailed structure of the chest will be described later. The clothing 105 is connected to the abdomen 104. Furthermore, the legs, including the right leg 106a and the left leg 106b, are connected to the lower part of the abdomen 104.

[0030] In the following description, the upper body, including the head 101, chest 102, and arm 103, will be referred to as the upper body. The lower body, including the clothing part 105 and leg 106a, will be referred to as the lower body. The upper body and lower body are connected by the abdomen 104. The chest 102, abdomen 104, and clothing part 105 will also be collectively referred to as the torso. Hereinafter, the thoracic joint structure of the chest 102 and the shoulder joint structure connecting the arm 103b to the chest 102 by a component having a cylindrical shaft will be described as movable structures (joint structures) of this embodiment. However, this is not intended to limit the invention; the movable structures described below are not limited to the thoracic joint and shoulder joint, and can be applied to other joints, such as the cervical joint connecting the head and the hip joint connecting the legs.

[0031] Figure 1B (b) shows an exploded perspective view of the chest 102 and left arm 103b, which are part of the upper body. As shown, the left arm 103b is connected to the shoulder member of the chest 102 by means of a spherical connector, in a manner that allows it to rotate relative to the shoulder member. Since the structure of the right arm 103a is the same, its description is omitted. In the following description, the structure of the shoulder joint related to the left arm 103b will be described, but the structure of the shoulder joint related to the right arm 103a is also the same.

[0032] <Structure of the upper body>

[0033] Next, refer to Figure 2 The detailed structure of the upper body of the model toy 100 of this embodiment, including the chest 102 and the left arm 103b, will be described. Figure 2 (a) represents an exploded three-dimensional view of the upper body. Figure 2 (b) represents an exploded perspective view of the multiple components that make up the chest 102. Figure 2 (a) is with Figure 1B The same diagram as (b) is used, therefore, the description is omitted.

[0034] like Figure 2As shown in (b), the chest 102 is composed of components 201 to 206, and a component 207b (the fourth component) is rotatably connected to the end of the left arm 103b. Component 201, corresponding to the first component, serves as the base of the thoracic and shoulder joints. Components 202a and 202b, corresponding to the second component, serve as movable axes of the shoulder joints, and are at least partially formed in a cylindrical shape serving as a rotation axis. Components 202a and 202b are rotatably connected to component 201. Components 203a and 203b, corresponding to the third component, are assembled to components 202a and 202b, respectively. The right arm 103a and left arm 103b are rotatably connected to components 203a and 203b, respectively.

[0035] Component 204 is assembled from above to component 201 and is rotatably connected to component 205, which forms part of the neck joint. Component 206 is assembled from the front to component 201 and forms part of the chest 102.

[0036] <Detailed Structure of the Shoulder Joint>

[0037] Next, refer to Figure 3A , Figure 3B The detailed structure of the shoulder joint of the model toy 100 of this embodiment will be described. Figure 3A An exploded 3D view showing the components that make up the shoulder joint. Figure 3B This section shows the assembly structure of components 202b and 203b. Here, the structure of a portion of the left shoulder, including the thoracic and shoulder joints, is described, but the structure of the right shoulder is similar and therefore omitted.

[0038] like Figure 3A As shown, component 201 is configured to include at least a cylindrical portion 311, recesses 312a and 312b, and cylindrical portions 313a and 313b. The cylindrical portion 311 is a connecting portion for connecting component 204. In the recesses 312a and 312b, components 202a and 202b are inserted to their deepest parts as indicated by the dashed arrows and are connected to be rotatable. The cylindrical portions 313a and 313b are connecting portions for connecting component 206.

[0039] Component 202b is configured to include at least a cam 321b, a groove 322b, a cylindrical portion 323b, and a protrusion 324b. The cam 321b is used to convert the rotational motion of component 202b into linear motion, forming a cam mechanism that utilizes the rib formed in component 201 (described later) as a guide. Therefore, the cam 321b is located at the lower end of a cylindrical shaft and is formed as a partially protruding circular shape. Thus, the protrusion of the cam 321b engages with the rib, thereby converting the rotational motion into linear motion. The groove 322b is formed along the outer periphery of the cylindrical shaft of component 202b and is embedded deep into the recess 312b of component 201. The cylindrical portion 323b is a connecting portion connected to component 203b. The protrusion 324b is a connecting portion connected to component 203b, and is embedded in the recess formed in component 203b (described later), functioning as a locking portion.

[0040] Component 203b is configured to include at least recesses 331b, 332b, and 333b. A cylindrical portion 323b of component 202b is connected to recess 331b. A spherical connecting portion of component 207b, located at the end of the left arm portion 103b, is rotatably connected from the left side of recess 332b. Furthermore, as shown... Figure 3B As shown, the recess 333b functions as a fixed window into which the protrusion 324b of component 202b is embedded.

[0041] <Detailed structure of the base>

[0042] Next, refer to Figure 4 The detailed structure of the base that forms part of the chest and shoulder joint in this embodiment will be described. Figure 4 (a) and Figure 4 (b) represents the top view of component 201, and shows the connection state with component 202b.

[0043] As described above, recesses 312a and 312b are formed in component 201 for inserting components 202a and 202b. Recesses 312a and 312b are formed from two regions: a first region 401a and 401b, and a second region 402a and 402b, respectively. The first regions 401a and 401b are located at the depth of the recesses 312a and 312b. On the other hand, the second regions 402a and 402b are located near the openings of the recesses 312a and 312b. Therefore, the second region 402 is located further outward from the center of the model toy 100 compared to the first region 401. The first region 401 and the second region 402 are formed continuously.

[0044] like Figure 4As shown in (a), component 202b is inserted from the opening of recess 312b and into the depth of the first region 401b. In the model toy 100, with the left arm 103b in its normal, inactive position, component 202b is located in the first region 401b. In this normal state, component 202b can rotate inward or outward by rotating in the direction of the arrow.

[0045] In order to make component 202b from Figure 4 When state (a) rotates counterclockwise, the cam mechanism converts the rotational motion into linear motion, such as... Figure 4 As shown by the dashed arrow in (b), component 202b moves along the shape of recess 312b toward the second region 402b. In conjunction with this movement, the left arm 103b, connected to components 202b and 203b, also moves in the same direction. As a result, the left arm 103b moves away from the center of the model toy 100. That is, the left arm 103b is in an outward-opening state. In this state, component 202b is also connected to be able to rotate in the direction of the solid arrow. Thus, components 202a and 202b are connected to be able to move between the first regions 401a and 401b and the second regions 402a and 402b of the recesses 312a and 312b formed in component 201.

[0046] <Movement of the movable axis>

[0047] In the following, refer to Figure 5 The movement of the movable axis of the shoulder joint constituting this embodiment will be described. Figure 5 (a) and Figure 5 (b) represents a perspective view of parts 201 and 202b viewed from below.

[0048] Figure 5 (a) shows the appearance of component 202b rotating within the first region 401b of recess 312b. In component 201, besides using… Figure 3A , Figure 3B In addition to the described structure, it also includes ribs 314a and 314b. Ribs 314a and 314b are formed near the outer periphery of recesses 312a and 312b, and their partial (wall surfaces) are formed to gradually approach the outer periphery of recesses 312a and 312b from a predetermined position. When component 202b rotates in the direction of the arrow, at a certain stage of rotation, cam 321b abuts against the wall surface of rib 314b. It is formed such that from the position where cam 321b and rib 314b abut, the wall surface further approaches the outer periphery of recess 312b.

[0049] Figure 5(b) indicates that component 202b is removed from Figure 5 The state of (a) has been further rotated. This is how component 202b is made to rotate from... Figure 5 When the component 202b rotates further in state (a), the cam 321b moves across the rib 314b, changing the rotational motion of the component 202b into linear motion. It is then subjected to force as indicated by the arrow (prescribed direction) and moves along the rib 314b towards the second region 402b of the recess 312b. Since no rib 314b is formed around the periphery of the second region 402b, there is no component for the cam 321b to abut against, even when the component 202b rotates. In other words, the movable area of ​​the component 202b in the second region 402b is not restricted by other components. Therefore, according to this embodiment, the component 202b is configured to move between the first region 401b and the second region 402b of the recess 312b while maintaining rotational motion.

[0050] <Shoulder joint movements>

[0051] In the following, refer to Figure 6 The movement of the shoulder joint in this embodiment will be explained. Figure 6 (a) and Figure 6 (b) shows a top view of the chest 102 and the left arm 103b. Here, the movable area of ​​the left arm 103b will be described with the component 201b positioned in the first region 401b and the second region 402b respectively.

[0052] Figure 6 (a) indicates the position of component 201b in the first region 401b of recess 312b. In this case, the left arm 103b is in a state of contact with the chest 102 and clamped. Consequently, component 203b, which forms part of the shoulder joint, is in a state of contact with component 206 on the front surface of the chest 102. In this state, component 206 and other components restrict the movable area of ​​the left arm 103b with component 202b as the movable axis.

[0053] Figure 6 (b) indicates the position of component 201b in the second region 402b of recess 312b. In this case, as shown by the dashed arrow, the left arm 103b... Figure 6 The state of (a) moves outward from the center of the model toy 100. Therefore, as indicated by reference numeral 601, space can be ensured between component 203b and component 206 to expand the movable area of ​​the left arm 103b. Thus, according to this embodiment, space can be ensured at the shoulder joint to reduce interference from other components, and the movable area using component 202b as a movable axis can be expanded.

[0054] As explained above, the model toy of this embodiment includes: a first component having a recess; and a second component having a cylindrical shaft, the cylindrical shaft being connected to the recess of the first component in a manner rotatable relative to the recess of the first component. The second component is movable between a first region and a second region formed in the recess, performing a rotational movement about the cylindrical shaft as a center in each region. Thus, in the model toy, a joint structure that ensures movable space to expand the movable area can be realized.

[0055] <Second Implementation>

[0056] The second embodiment of the present invention will be described below. In this embodiment, a mechanism that restricts the mobility of the shoulder joint will be described. In the above embodiment, within the limits of the other components, the rotational movement of the component (second component) 202b constituting the shoulder joint is allowed to proceed freely. In this case, the movable area can be expanded to a larger range, but on the other hand, movement beyond the natural range of motion is allowed. For example, when the shoulder joint including component 202b is rotated inward, a gap is generated in the component near the scapula on the back side, resulting in a deterioration in the aesthetic appearance during movement.

[0057] Therefore, in this embodiment, the following structure is provided: a limiting member (limiting part) is provided on the second component to limit the rotation of the second component, thereby limiting the rotational movement of the second component. This allows for the maintenance of shoulder joint rotation and limits unnecessary range of motion. Furthermore, in the following descriptions, the same reference numerals are used for structures identical to those in the first embodiment described above, and further explanation is omitted.

[0058] <Structure of the movable shaft>

[0059] First, refer to Figure 7 The structure of the second component in this embodiment will be described. Figure 7 (a) represents a perspective view of component 700b, which is the second component. Figure 7 (b) indicates the way that component 700b is connected to component 201, which is the first component.

[0060] like Figure 7 As shown in (a), in addition to the structure of component 202b in the first embodiment described above, component 700b also includes a limiting member 701b. The limiting member 701b is configured to partially protrude from the side of the cylindrical movable shaft of component 700b, and functions to limit the rotation of cam 321b.

[0061] Figure 7(b) indicates the state in which component 204 is assembled to component 201, and component 201 is connected to component 700b, which is the second component. In this state, when component 700b is rotated inward (clockwise in the figure), the limiting member 701b of component 700b collides with the cylindrical portion 702 of component 204, limiting further rotational movement. Thus, the rotation angle of cam 321b can be limited to slightly more than 10 degrees (a predetermined angle). Furthermore, the limited rotation angle (predetermined angle) can be arbitrarily set according to the specifications of the model toy used, and is not limited to the present invention.

[0062] <Examples of shoulder joint movements>

[0063] Next, refer to Figure 8 The movement example of the shoulder joint in this embodiment will be described. Figure 8 (a) and Figure 8 (c) represents the top view section of the shoulder joint in the first embodiment described above. Figure 8 (b) and Figure 8 (d) represents the top view section of the shoulder joint in this embodiment.

[0064] In making the shoulder joint from Figure 8 When the state of (a) is rotated inward, that is, when component 202b is rotated clockwise as shown in the figure, as Figure 8 As shown in (c), the component 203b constituting the shoulder joint creates a gap 801 on the back side, away from component 201. Such a gap may be a major cause of discomfort. However, on the other hand, by increasing the movable area of ​​component 202b, which serves as a movable axis, a wide variety of movements can be achieved.

[0065] On the other hand, when the component 700b of this embodiment is moved from... Figure 8 When state (b) rotates clockwise as shown in the diagram, as Figure 8 As shown in the dashed area 803 of (d), the limiting member 701b of component 700b collides with part 702 of component 204, thus limiting the rotation range of component 700b. Therefore, according to this embodiment, as component 700b rotates, component 203b constituting the shoulder joint moves slightly away from component 201, creating some gap 802 on the spinal side. However, if... Figure 8 Comparing the gap 801 shown in (c), it can be seen that it has become much smaller. Thus, according to this embodiment, by limiting the movable area of ​​local movements of the shoulder joint, movements that deteriorate the aesthetic appearance can be limited.

[0066] As explained above, in the model toy of this embodiment, in addition to the structure of the above embodiment, a limiting member is also formed on a portion of the side of the second component. When the cylindrical shaft rotates by a predetermined angle in the first region, the limiting member collides with other components, thereby limiting the rotation of the cylindrical shaft. Thus, according to this embodiment, unnecessary movable areas in the joint structure can be appropriately limited, preventing movements that cause discomfort.

[0067] <Variation Example>

[0068] This invention is not limited to the embodiments described above, and various modifications and alterations are possible within the scope of the invention's intent. In the above embodiments, an example of applying the movable structure to a shoulder joint was described, but this does not limit the intent of the invention, and it can also be used in other locations. For example, it can also be used in joints such as the neck joint and the hip joint connecting the leg. Furthermore, the shape of the recess and rib for receiving the movable shaft of the joint formed at the base can be arbitrarily shaped to match the shape of the location where the invention is applied.

[0069] Furthermore, examples of model toys have been given as examples, but the shape of model toys (human figures) is not particularly limited, and includes a wide variety of shapes such as humans, animals, robots, insects, dinosaurs, and virtual life forms. Moreover, as long as it includes movable parts, the shape of a model toy is not particularly limited.
