Description

The present invention relates to humanoid toys.

There is known a humanoid toy that a user can complete by assembling parts for each region and play with the toy in various poses. For example, Patent Literature 1 discloses that the shoulder joint itself is supported by a vertical axis and rotated around the vertical axis so that it can swing back and forth with respect to the body. is disclosed (see FIG. 5 of Patent Document 1).

JP-A-2001-96073

The design of a humanoid robot is known as an example of the design theme of humanoid toys. Many of the humanoid toys designed as humanoid robots have straight, mechanical designs covered with armor for the main trunks such as the chest, abdomen, and waist. and. Conventionally, those trunk parts have been designed as one box-shaped part or one shell-shaped part. For this reason, it was easy for the movable parts provided on the trunk to move freely.

For example, in TV anime and manga about humanoid robot heroes, there are so-called "definitive poses" such as posing with both hands stretched out in front of the chest and holding a sword or gun, or swinging a sword down on a robe. And "pretentious poses" often appear. As a user, I would like to reproduce it with a humanoid toy. Specifically, when the humanoid toy is viewed from above, it is desired to reproduce a pose in which the shoulder is pushed forward with respect to the body.

According to the configuration of Patent Document 1, by connecting and pivoting the arms to the body with a vertical axis (support shaft 6 in Patent Document 1), the shoulders can be axially rotated about the vertical axis from the horizontal position. It can be displaced to a position diagonally forward of the torso. However, since the vertical axis is fixed to the torso, the swing range of the arm was insufficient to reproduce the "decisive pose" and "pretentious pose". If an attempt is made to secure a sufficient swing angle, a considerable amount of space must be provided to prevent interference between the torso and shoulder joints (corresponding to the front portion 69 in FIGS. 5 and 6 in Patent Document 1). However, the space appears on the front side of the body and the shoulder joint is exposed (in FIG. 6 of Patent Document 1, the space appears and the shoulder joint is exposed), and the attractiveness of the exterior design is significantly impaired. It was possible.

It is an object of the present invention to widen the movable range and facilitate reproduction of a "decisive pose" or a "pretentious pose".

The present invention is a humanoid toy comprising a central chest, arms, and side chests connected to the central chest and the arms, and the connection structure between the central chest and the side chests is The humanoid toy has a structure in which the side chest can be displaced in a direction in which the arm protrudes in front of the humanoid toy. In addition, the present invention is a humanoid toy having a chest, comprising a central chest forming the left and right central portions of the chest, arms, and side chests connected to the central chest and the arms, The central chest is assembled by attaching a central chest exterior part to a central chest base, and the side chest is assembled by attaching a side chest exterior part to a side chest base, the central chest exterior part and the side chest exterior. The external appearance of the chest is formed by parts, and the connection structure between the central chest and the side chest is a structure in which the side chest can be displaced in the direction in which the arm protrudes in front of the humanoid toy. A humanoid toy having

Further, in the present invention, the connection structure may have a structure in which the rear side of the lateral chest in the direction of protrusion can be displaced more outward than the front side in the direction of protrusion.

Further, in the present invention, the shoulder may be connected to the side chest so that the shoulder can swing in the projecting direction.

Further, in the present invention, the connecting structure has a closed link structure for planar movement including the projecting direction, both ends of the closed link structure are provided at the central chest, and an intermediate link The side thorax may be connected to the central thorax.

Further, in the present invention, the rear end of the both ends of the closed link structure may be slidable in a predetermined sliding direction.

Further, in the present invention, the sliding direction may be set in a direction diagonally forward and outward when viewed from the back side of the humanoid toy.

Further, in the present invention, the displaceable range of the side thorax is defined as a position where the side thorax is horizontally aligned with the central thorax in a top view is a rear limit position, and a position where the side thorax is most moved in the projecting direction is a front limit position. The range may be set as follows.

According to the present invention, it is possible to provide a humanoid toy that has a wider movable range and can easily reproduce a "fixed pose" or a "pretentious pose".

FIG. 1 is a perspective external view schematically showing the upper body portion of a humanoid toy to which the present invention is applied.
The humanoid toy 2 is a toy configured by assembling parts for each part. In the illustrated example, the head 3, chest 4, abdomen 5, arms 6, and backpack 7 of the humanoid toy 2 are selectively illustrated, but parts not illustrated are also included (for example, , waist and legs) are also provided as appropriate. The user can arbitrarily change the relative orientations and relative postures of these parts, and enjoy various poses of the humanoid toy 2 .

The chest 4 of this embodiment has a central chest part 41 , a left chest part 42 and a right chest part 43 .
The central chest part 41 is a part that constitutes the trunk, and forms the left and right central portions of the chest 4 in this embodiment. The left chest part 42 and the right chest part 43 are parts that constitute a part of the trunk or the appearance of the trunk, and correspond to the side chest. In this embodiment, they form a right half corresponding to a portion of the right shoulder and right lung, and a left half corresponding to a portion of the left shoulder and left lung.

The posture in FIG. 1 is an upright pose in which the central chest part 41, the left chest part 42, and the right chest part 43 are arranged side by side. The outer surface of the chest part 42 and the outer surface of the right chest part 43 form an integrally connected appearance as the chest part 4 .

In the humanoid toy 2 of the present embodiment, the left chest part 42 and the right chest part 43 are configured to be displaceable with respect to the central chest part 41 in the forward direction of the humanoid toy 2, i.e., the arm sticking-out direction. . As a result, the movable range in the projecting direction of the arm is wider than before, making it easier to reproduce the "decisive pose" and "pretentious pose".

[Explanation about the movable range of the arm]
FIG. 2 is a top view schematically showing the upper body portion of the humanoid toy 2 in this embodiment,
(1) "Upright Pose" in which the central chest part 41, the left chest part 42, and the right chest part 43 are arranged side by side, and the arms 6 are lowered straight;
(2) "Simple arm thrusting pose" in which the arms 6 are projected forward while the central chest part 41, the left chest part 42, and the right chest part 43 are aligned side by side;
(3) With the central chest part 41, the left chest part 42, and the right chest part 43 left and right side by side, the arm 6 is swung forward about the shoulder connecting vertical shaft 423, and the sword or the gun is wielded with both hands. "Standing Arm Thrusting Pose" where the arm 6 is protruding in front of the chest as if standing in front of the chest.
(4) Displaced left chest part 42 and right chest part 43 are displaced forward, and arm 6 is protruded in front of the chest as if holding a sword or a gun with both hands in front of the chest "displacement stance arm thrusting pose";
are shown respectively.

As shown in FIG. 2(1), in the upright pose, the outer surface of the central chest part 41, the outer surface of the left chest part 42, and the outer surface of the right chest part 43 are integrally connected to form the chest 4. forming This appearance is the same as the character setting in anime and manga, and there is no reduction in attractiveness in terms of appearance design. As shown in FIG. 2(2), simply sticking out the arm does not similarly reduce the attractiveness of the appearance design.

Here, the humanoid toy 2 is made to hold a sword or a gun with both hands in front of the chest, in which the shoulder joints are greatly bent (bent deeply), such as a "fixed pose" or a "pretentious pose".
Normally, when a person holds a sword or gun in front of their chest, if they are simply holding it, their back is relatively flat as in normal times, and only their arms are stretched forward. On the other hand, in the stance of a person who is desperately trying to fight with a high level of combat awareness, both shoulders and the entire back form a strong arc. Creates good looks.

As shown in FIG. 2(3), even if the central chest part 41, the left chest part 42, and the right chest part 43 are arranged side by side, the vertical axis connecting the arms 6 and the chest 4 (shoulder connecting upper and lower parts) 423), it is possible to swing forward and backward, giving the impression that the shoulders are protruding forward more than in the previous "simple arm thrusting pose". However, the amount of protrusion of the shoulder is small, and the impression of "just standing up" cannot be wiped out.

However, when the present embodiment is applied and the left chest part 42 and the right chest part 43 are displaced forward of the central chest part 41, as shown in FIG. 2(4), the amount of shoulder protrusion increases. . That is, the left chest part 42 and the right chest part 43 can be displaced so as to move forward of the humanoid toy 2 relative to the central chest part 41 . As a result, when viewed from above, the 3 parts of the center chest part 41, left chest part 42, and right chest part 43 are arranged to create a "strong arc" that creates a cool "decisive pose" or "showing off pose". Become.

Such a "strong arc" arrangement has the same effect even when it is applied to only one shoulder joint. Therefore, for example, the humanoid toy with a conventional structure that does not displace the shoulder joint even in a "decisive pose" in which a sword held in one hand is swung diagonally down, or a "pretentious pose" in which a gun held in one hand is thrust diagonally forward. It looks much better than the same pose in .

[Description of link structure]
Next, an example of a connecting structure capable of displacing the left chest part 42 and the right chest part 43 with respect to the central chest part 41 in the direction in which the arm protrudes will be described in detail. Since the left chest part 42 and the right chest part 43 have bilaterally symmetrical structures, the relationship between the central chest part 41 and the left chest part 42 will be described below as a representative example.

FIG. 3 is a link diagram for explaining an example of the connection structure between the central chest part 41 and the left chest part 42, and is a top view of the action plane including the projecting direction of the arm 6. As shown in FIG.
In the present embodiment, the central chest part 41 and the left chest part 42 constitute a five-bar slider-crank closed link structure that operates on a plane including the projecting direction of the arm 6 .

Specifically, the central chest part 41 is used as a first link, the left chest part 42 is used as a second link, and the front parts are connected by a front link part 46 (third link). The front link part 46 is connected to the central chest part 41 by a fixed joint 50 and is connected to the left chest part 42 by a front joint 51 .

In addition, the central chest part 41 and the left chest part 42 are connected at their respective rear parts via a rear link part 47 (fourth link) and a slider 48 (fifth link). One end of the rear link part 47 is connected to the left chest part 42 by a rear joint 52 , and the other end is connected to the slider 48 by a slider joint 53 .

The slider 48 is fixed to the rear end portion of the central chest part 41 with its sliding direction set in a direction diagonally forward and outward when viewed from the back side of the humanoid toy 2 . The illustrated example shows the connection structure between the central chest part 41 and the left chest part 42, so that the sliding direction is obliquely forward left of the humanoid toy 2. As shown in FIG. In the case of the connection structure between the central chest part 41 and the right chest part 43, the sliding direction is set so that the humanoid toy 2 faces obliquely forward right.

By adopting such a five-bar slider-crank type closed link structure, the left chest part 42 is set to the rear limit position where the left chest part 42 and the center chest part 41 are aligned left and right, as shown in FIG. 3(1). , through the intermediate position shown in FIG. 3(2), and as shown in FIG. At the rear limit position, the slider 48 is at the position closest to the central chest part 41, slides leftward as the forward displacement progresses, and reaches the front limit position when fully slid.

In addition, in the intermediate position, the left chest part 42 assumes an inclined posture such that the rear end portion protrudes outward. In other words, the rear side in the projection direction of the left chest part 42 is displaced to the outside (to the left because it is the left chest part 42) from the front side in the projection direction. By selectively using this intermediate posture, it is possible to make the humanoid toy 2 take a pose in which the left arm wraps around the front of the chest.

[Description of parts configuration]
Next, an example of a configuration of parts for realizing such a closed link structure will be described.
FIG. 4 is a perspective exploded view of a part relating to the connection structure between the central chest part 41 and the left chest part 42, as seen obliquely from the front left. The balloons in the figure show views from different angles to facilitate understanding of the three-dimensional shape of each part.

The connection structure between the central chest part 41 and the left chest part 42 includes a central lower chest part 41d fixed on the abdomen 5, a rear link part 47, a central upper chest part 41u, a front link part 46, and a left side. It has a chest base 421 and a shoulder connecting part 49 .

The central chest lower part 41 d is fixed above the abdomen 5 . The central chest lower part 41d has lower slide rail long holes 412 opening upward at the left and right rear portions with the head connecting projection 411 for connecting the head 3 in the center. These left and right lower slide rail long holes 412 are elements for realizing the slider 48 (see FIG. 3) of the link mechanism, and the longitudinal direction of the holes is the sliding direction. That is, the left lower slide rail elongated hole 412 is provided on a horizontal plane so as to have a longitudinal direction toward the obliquely left front of the humanoid toy 2 . The right lower slide rail elongated hole 412 is provided on a horizontal plane so as to have a longitudinal direction toward the oblique right front of the humanoid toy 2 .

The rear link part 47 has a cylindrical rear joint bearing portion 471 that is open vertically at one end of the rod, and has an upper slide pin 472u and a lower slide pin 472d on the upper and lower surfaces of the other end.

The central chest upper part 41u is fixed to pivotably support the front link parts 46 in the front left and right directions with a head mounting hole 413 fitted to the head connecting projection 411 of the central chest lower part 41d in the center. It has a joint shaft 414 and upper slide rail long holes 415 on the left and right rear. These left and right upper slide rail long holes 415 are elements for realizing the slider 48 (see FIG. 3), and the longitudinal direction of the holes is the sliding direction. That is, the left upper slide rail elongated hole 415 is provided on a horizontal plane so as to have a longitudinal direction toward the obliquely left front of the humanoid toy 2 . The right upper slide rail long hole 415 is provided on a horizontal plane so as to have a longitudinal direction toward the oblique right front of the humanoid toy 2 .

The front link part 46 is a structural element having a box-end wrench shape, and has a front joint bearing portion 461 that is open vertically at one end of the rod, and a cylindrical shape that is open vertically at the other end of the rod. of fixed joint bearings 462 .

The left chest base 421 is a base part of the left chest part 42 and corresponds to the left chest part 42 with the front exterior parts removed. The left chest base 421 frontwardly forms the main volume of the left chest, and a support piece 422 extends rearward from its rear end surface. A vertical shaft 423 for shoulder connection, which is a pivot of the shoulder connection part 49 and functions to swing the arm back and forth, protrudes upward from the upper surface of the shaft base piece 422 . A front joint shaft 424 projects downward from the front of the bottom surface of the shaft base piece 422, and a rear joint shaft 425 projects downward from the rear of the bottom surface.

The shoulder connection part 49 is a part that connects the left chest part 42 and the left arm part 6, and is composed of a shoulder connection front/rear axis part 491, a shoulder connection left/right axis part 492, and a left chest upper surface exterior part 493. , consists of

The shoulder connecting front/rear shaft part 491 is a tubular body that opens vertically and has a shoulder connecting vertical bearing portion 494 through which the shoulder connecting vertical shaft 423 is inserted. protruded.

The shoulder connecting left/right shaft part 492 is a tubular body that opens forward and backward, and has a shoulder connecting front/rear bearing portion 496 through which the shoulder connecting front/rear shaft 495 is inserted. A shaft 497 protrudes.

[Explanation of assembly procedure]
Next, a procedure for assembling the parts relating to the connection structure between the central chest part 41 and the left chest part 42 will be described.

5 to 7 are perspective views for explaining the procedure for assembling parts around the chest.
In addition, in these figures, the connection structure between the central chest part 41 and the left chest part 42 is selectively illustrated for easy understanding. The procedure for assembling the connection structure between the central chest part 41 and the right chest part 43 is not shown, but since the connection structure is bilaterally symmetrical, it can be assembled in the same manner as shown in these figures.

First, as shown in FIG. 5, the rear link part 47 is attached to the central lower chest part 41d from above, and then the central upper chest part 41u is attached.
Specifically, the lower slide pin 472 d of the rear link part 47 is fitted into the lower slide rail long hole 412 and attached. Then, the upper slide rail long hole 415 is fitted into the upper slide pin 472u of the rear link part 47, and the central chest upper part 41u is put thereon. As a result, the upper slide rail long hole 415 and the lower slide pin 472d face each other with the rear link part 47 sandwiched therebetween, and function as a rail that guides the rear link part 47 in the sliding direction.

Next, as shown in FIG. 6, the front link parts 46, the left chest base 421, and the shoulder connecting parts 49 are assembled.
Specifically, the fixed joint bearing portion 462 of the front link part 46 is fitted onto the fixed joint shaft 414 of the central upper chest part 41u from above. Next, the front joint shaft 424 of the left chest base 421 is fitted into the front joint bearing 461 of the front link part 46, and the rear joint shaft 425 is fitted into the rear joint bearing 471 of the rear link part 47. Assemble from above. Then, the pre-assembled shoulder connecting part 49 is assembled from above such that the shoulder connecting vertical shaft 423 is inserted into the shoulder connecting vertical bearing portion 494 . As a result, the left arm 6 is connected to the left chest part 42 so as to be swingable forward in the projecting direction. The assembly of the parts related to the connection structure between the central chest part 41 and the left chest part 42 is basically completed at this point. Of course, although illustration is omitted, parts related to the connecting structure between the central chest part 41 and the right chest part 43 are also assembled in the same manner.

As shown in FIG. 7, other exterior parts are attached as appropriate to complete the chest area of the humanoid toy 2. As shown in FIG. In this embodiment, the left chest front exterior part 429 is attached from the front to the front of the left chest base 421, and the central chest front exterior part 418 is attached to the front of the central upper chest part 41u and the central lower chest part 41d from the front. Then, the central chest upper surface exterior part 419 is attached to the central chest upper part 41u from above. In addition, exteriors such as rear exterior parts are installed as appropriate.

[Description of operation]
Next, the operation of the connection structure between the central chest part 41 and the left chest part 42 will be described. 8A and 8B are diagrams for explaining the operation of the connection structure between the central chest part 41 and the left chest part 42. (1) Perspective external view of the chest area in the undisplaced state of the left chest part 42, (2) ) is a see-through top view of the inside of the chest showing the relative positional relationship of the parts related to the connecting structure in the non-displaced state. FIG. 9 shows the maximum displacement state of the left chest part 42 .

In FIG. 8, the left chest part 42 and the central chest part 41 are side by side in terms of appearance of the chest. Inside the chest, the left chest base 421 (shown only in dashed outline) is at its posterior limit position (see FIG. 3(1)).

When the left chest part 42 is displaced forward from here, as shown in FIG. It is swung forward while sliding in the left front direction. Then, the left chest base 421 reaches the front limit position (see FIG. 3 (3)), and the left chest front exterior part 429 and the shoulder connecting parts 49 are also integrated with the left chest base 421 forward with respect to the central chest part 41. Displaced as if sliding. From the appearance of the chest, the left chest part 42 appears to protrude by sliding forward from the side-by-side position with the central chest part 41 .

The left and right shoulder connecting shaft 497 of the shoulder connecting part 49 to which the left arm 6 is actually connected also moves forward due to the displacement. Therefore, the movable range of the shoulder joint is widened while suppressing the reduction in the appeal of the appearance design, making it easier to reproduce the "decisive pose" and "pretentious pose".

As described above, in the humanoid toy 2 according to the present embodiment, the chest 4 is divided into the central chest part 41 and the side chest parts 42 and 43, and the side chest parts 42 and 43 are divided into the central chest part 41. It can be displaced forward. In other words, the position itself where the arm 6 is connected to the chest 4 can be displaced forward. Therefore, it is possible to expand the range of motion around the shoulder joints compared to conventional humanoid toys while suppressing the reduction in the attractiveness of the appearance design, making it easier to reproduce the "decisive pose" and "pretentious pose".

Further, according to the humanoid toy 2 in the main character form, the rear side in the projecting direction of the side chest parts 42 and 43 is displaced outward from the front side in the projecting direction. In other words, the posture is such that the shoulders protrude obliquely forward and outward. By selectively using this posture, it is possible to make the humanoid toy 2 take a "fixed pose" or a "pretentious pose" in which the arm wraps around the front of the chest.

Further, according to the humanoid toy 2 according to this embodiment, the connection structure can be realized by the closed link structure.

Further, according to the humanoid toy 2 according to the present embodiment, the displaceable range of the side chest parts 42 and 43 can be set to a range suitable for forward projection of the arm 6 .

[Modification]
It should be noted that the embodiments of the present invention are not limited to the above examples, and components can be appropriately added, omitted, or changed as long as the gist of the invention is not changed.

For example, in the above-described embodiments, a humanoid toy was used as an example of a toy, but it is not limited to a humanoid toy. the present invention can be applied.

Also, as an example of the movable part, in the above embodiment, the arm is given, but the name can be appropriately changed according to the design of the toy, such as neck, gun barrel, horn, tactile sensation, sensor, etc.

Also, as an example of the displacement direction, the front is exemplified, but it may be upward, downward, backward, etc. In order to reproduce the assumed "determined pose" or "pretentious pose", the displacement direction is appropriate in the direction in which the movable part protrudes. can be set.
