Description

The present invention relates to a toy arm structure.

There are known toys that allow the user to assemble and complete parts for each part and to play with various poses. For example, Patent Document 1 has a structure in which a ball joint connecting legs (corresponding to a femur joint in the human body) is swingably supported by a front-back axis fixed to a side portion in the lumbar region. The configuration of a humanoid toy that can achieve both an upright posture and a dynamic open leg posture by changing the interval between the ball joints is disclosed.

By the way, one of the themes of toy design is a large humanoid robot that appears in manga and TV animation. Humanoid toys designed as humanoid robots often have a design that mainly resembles a Western knight covered in armor. In that case, it is designed as a flowing and powerful form as if a muscular skeleton is hidden in it. For example, the arms and legs have contours that make the muscles bulge, as humans say, to emphasize strength.

Then, when a user purchases such a humanoid toy, he / she wants to make him / her make a “decision pose” or a “look-and-feel pose” that appears in manga and TV animation. For example, in a hanger (a parking lot for humanoid robots) before a sortie, a long equipment such as a rifle is held with one hand in a posture along the longitudinal direction of the equipment and the "pre-sortie pose". Can be said to be one of them.

However, since the modeling of the humanoid toy faithfully reproduces the design of the original combat robot, it is easy for inconvenience to occur in the movement of the movable parts.
For example, focusing on the parts of the hand part (meaning the part beyond the wrist), there are few movable parts of the wrist, and the movable range of the wrist is also limited. Therefore, for example, even if you try to equip the rifle along the direction of the arm in order to realize the determined pose of standing, the stock part interferes with the forearm part and the rifle is equipped in the hand part. There was a situation where I couldn't let him.

The problem that a specific fixed pose such as the pre-sortie pose cannot be reproduced is not limited to humanoid toys, and it is the same regardless of whether the overall design of the toy is humanoid or non-doll. Is. For example, animals, insects, imaginary creatures, robots, vehicles, etc. were the same as long as they had a design with an arm structure.

The present invention has been devised with the main object of providing a technique capable of reproducing a specific pose in which a specific equipment is attached to the arm structure in a toy having an arm structure.

An aspect of the present invention is a forearm portion having a hand portion that can be mounted so as to hold an accessory longer than the total length of the hand portion and a support portion that supports the hand portion, and the support portion is placed at a first position. When the equipment is attached to the hand portion, the forearm portion that can be changed to a second position that can reduce the interference between the equipment and the forearm portion as compared with the first position, and the forearm portion. It is a toy arm structure equipped with. Further, in the aspect of the present invention, the hand portion that can be mounted so as to hold an accessory longer than the total length of the hand portion, a support portion that supports the hand portion, and a pivotal support portion in which the support portion is rotatably provided. A forearm portion having a forearm base and a forearm base supporting the pivotal portion, and a slide pin projecting to one end side of the pivotal support portion is engaged with an elongated hole portion provided in the forearm base portion to support the pivotal portion. The part is changed to the first position and the second position where the interference between the equipment and the forearm can be reduced as compared with the first position when the equipment is attached to the hand part. Ri can toy arm structure der is, the forearm, the the supporting portion and the pivot portion includes a slidable slider unit relative to the front arm base, the second position, the slider portion It is a position where the length of the forearm portion is lengthened as compared with the first position by sliding, the forearm portion has a lock portion that locks the slide position of the slider portion, and the lock portion is the said. that has been provided on the exterior portion of the forearm.

The forearm portion supports the support portion and has a slider portion capable of changing the length of the forearm portion, and the second position is the second position as compared with the first position by sliding the slider portion. It may be a position where the length of the forearm is increased.

Further, by having a joint structure in which one end side is connected to the hand portion and a joint structure in which the other end side is connected to the support portion, the angle and posture of the hand portion can be changed with respect to the support portion. It may be further provided with a link portion to be provided.

Further, the forearm portion may have a lock portion that locks the slide position of the slider portion.

Further, the lock portion may be provided on the outer portion of the forearm portion.

Further, the forearm portion can be changed into a linear form and a bent form by changing the support angle of the support portion, and the first position is a position in which the linear form is formed. , The second position may be the position in which the bent form is formed.

Further, the equipment may be a part that imitates a firearm having a stock.

It is also possible to construct a humanoid toy having the above-mentioned arm structure.

FIG. 1 is a front view (front view) of a humanoid toy which is an example of an embodiment to which the present invention is applied. In addition, a part is represented by a silhouette for easy understanding. The direction notation indicated by the arrows in the figure indicates the front, back, left, and right for the humanoid toy 2.

The humanoid toy 2 is a toy that has a design that imitates a humanoid robot based on a TV anime or manga, and is made by assembling parts for each part. The humanoid toy 2 has a design with the motif of a Western knight covered with armor, and the arm structure 3 and leg structure are as if a muscular skeleton is hidden in it. It has a flowing and powerful form. Further focusing on the details, the arm structure 3 contoured by a thick solid line has an upper arm portion 4, a forearm portion 5, and a hand portion 6 (meaning a portion for gripping an object beyond the wrist). The portion of the forearm 5 facing the torso when standing upright is designed as if the muscles of a person are raised, and is expressed to be remarkably thicker than the forearm of a normal person.

The hand portion 6 is a fist-shaped integrally molded product having a ball joint stud 61 that realizes a wrist movable portion. The hand portion 6 has a five-fingered form, but they cannot be moved. The convex portion of the equipment is mounted on the hand portion 6 so as to have an equipment (a part prepared separately from the main body of the humanoid toy 2; a part prepared as a dress-up element). A mounting recess 62 having a polygonal cross section (for example, a rectangle when viewed from the insertion direction) is provided for inserting and fitting the toy.

Equipment includes specific equipment 7 designed to imitate tall weapons such as rifles and bazooka guns. The specific equipment 7 shown in FIG. 1 is intentionally shown as a side view so that the overall design can be easily understood.

The total length of the specific equipment 7 is at least longer than the total length of the hand portion 6, and the stock 72 is provided behind the pistol grip 71 inserted into the mounting recess 62. In the original story in which a humanoid robot modeled after the humanoid toy 2 appears, hold this special equipment 7 in one hand with your right hand on the hanger before the sortie, and wait in the so-called pre-sortie pose. The scenes of a cool sortie with a majestic BGM are drawn many times. For users of the humanoid toy 2, when decorating it, they want to pose before the sortie.

However, with the arm structure of a conventional humanoid toy, it is not possible to attach a tall part to the hand portion 6 so as to hold it like the specific equipment 7, and to make a pose before the sortie.

FIG. 2 is a front view of the right arm for explaining the problem of the conventional humanoid toy using the humanoid toy 2. FIG. 3 is a side view of the right arm of FIG. 2 as viewed from the right side when facing the front.
Since the left and right arm structures 3 of the humanoid toy 2 of the present embodiment are symmetrical, the following description will be made with the right arm structure 3 as a representative, and the illustration and description of the left arm will be omitted.

It is difficult to understand from the front view of FIG. 2, but as can be seen by referring to FIG. 3, in the conventional humanoid toy, the pistol grip 71 of the specific equipment 7 is attached to the hand portion 6 from the front side of the arm structure portion 3. Even if I try to put it on, I can't get close to it. As shown by the alternate long and short dash line in FIG. 3, in order to make the pose before the sortie as in the original, the arm structure 3 is in a state of being extended along the longitudinal direction of the specific equipment 7, and the gun of the specific equipment 7 is used. The grip 71 must be mounted in the mounting recess 62 of the hand portion 6 and the stock 72 must be positioned inside the forearm portion 5 (body side).

However, with conventional humanoid toys, interference points occur, and it is not possible to pose before the sortie as in the original. Specifically, for example, if a posture in which the arm structure 3 is extended along the longitudinal direction of the specific equipment 7 is first created, and the gun grip 71 of the specific equipment 7 is attached to the hand portion 6 in that posture. To do. In order to make the arm structure 3 in an extended posture, the hand portion 6 is rotated outward with the stud 61 of the ball joint 60 as a fulcrum, but as shown by the white arrow in FIG. 2, the hand portion 6 is used as an exterior part. Due to contact, its rotation is limited. Further, when the gun grip 71 of the specific equipment 7 is attached to the hand portion 6 in that posture, the lower end of the stock 72 is on the front side of the forearm portion 5 as shown by the shaded arrows in FIGS. 2 and 3. It interferes and cannot be installed.

Now, the arm structure 3 of the present embodiment that can realize the pre-sortie pose will be described.
FIG. 4 is a simplified view of the structure of the arm structure 3 of the present embodiment, and a part of the structure is shown in cross section. The forearm portion 5 of the arm structure 3 of the present embodiment has a support portion 11 that connects the hand portion 6 with a ball joint, a pivot portion 12 that swingably supports the support portion 11, and a pivot portion 12 that can slide. It has a forearm base 14 to support. The outside of the forearm portion 5 is covered with an exterior portion 16 that covers at least a part of these.

The forearm base 14 has a connecting structure portion with the upper arm portion 4 on one end side (upper end side in FIG. 4), and the pivot portion 12 is provided on the other end side (lower end side in FIG. 4). It is supported via the slide mechanism portion 20.

The slide mechanism portion 20 includes a slide guide 21 provided on the forearm base portion 14 along the longitudinal direction of the forearm portion 5, and a slide pin projecting from one end side (upper end side in FIG. 4) of the pivot support portion 12. It is realized by engaging with 22.

On the other hand, on the other end side of the pivotal support portion 12 (lower end side as referred to in FIG. 4), the support portion 11 is swingably supported via the swing mechanism portion 30.

The swing mechanism portion 30 is formed by fitting a swing shaft 31 projecting from the pivot portion 12 into a shaft hole 32 provided on one end side (upper end side in FIG. 4) of the support portion 11. This is realized, and the support portion 11 is swingably supported in the inward / outward direction of the arm structure 3 (the direction away from the body portion of the humanoid toy 2; the left-right direction in FIG. 4). It is assumed that the swing shaft 31 and the shaft hole 32 are set in an appropriate fitting relationship in which the swing posture is maintained.

Further, on the other end side of the support portion 11 (lower end side as referred to in FIG. 4), a socket 63 that fits with the stud 61 of the hand portion 6 is provided. That is, the support portion 11 and the pivot portion 12 are connected by a ball joint 60.

The support portion 11 and the pivot portion 12 form a slider portion 10 that slides integrally with the forearm base portion 14 while supporting the hand portion 6, and the length of the forearm portion 5 can be changed. Then, the support portion 11 swings with respect to the pivotal support portion 12, so that the forearm portion 5 can be changed to a linear form or a bent form by changing the support angle of the support portion 11.

Further, the forearm portion 5 has a lock portion 40 that locks the slide position of the slider portion 10. The lock portion 40 is realized by engaging the lock pin 43 projecting from the pivot portion 12 with the first lock hole 41 or the second lock hole 42 provided in the exterior portion 16.

The first lock hole 41 is provided at a position where the pivot portion 12 is brought close to the forearm base portion 14, that is, the forearm portion 5 is the shortest, and is fitted with the lock pin 43. The second lock hole 42 is provided at a position where the pivot portion 12 is most distant from the forearm base portion 14, that is, the forearm portion 5 is the longest, and is fitted with the lock pin 43.

FIG. 5 is a diagram for explaining a procedure for changing the position of the support portion 11. To attach the specific equipment 7 to the humanoid toy 2, the operation is as follows: FIG. 5 (1) → FIG. 5 (2) → FIG. 5 (3) → FIG. 5 (4).

Specifically, when the specific equipment 7 is not attached, the support portion 11 is in the "first position" as shown in FIG. 5 (1). At this time, the forearm portion 5 has the shortest and linear shape. Then, in order to mount the specific equipment 7, the exterior portion 16 is first shifted or removed to release the engagement between the first lock hole 41 and the lock pin 43, and the lock portion 40 is released. As a result, the slide mechanism portion 20 becomes movable.

Next, as shown in FIG. 5 (2), the pivot portion 12 is pulled out from the forearm base portion 14 to bring the forearm portion 5 into the longest state. Subsequently, as shown in FIG. 5 (3), the support portion 11 is swung with respect to the pivot portion 12 inward of the forearm portion 5. As a result, the forearm portion 5 has the longest and bent shape, and the support portion 11 does not interfere with the forearm portion 5 when the specific equipment 7 is attached to the hand portion 6 as compared with the first position. It means that it has been moved to the second position, which is the position. The second position is a position where the specific equipment 7 is less likely to interfere with the forearm portion 5 than the first position, and the interference between the specific equipment 7 and the forearm portion 5 can be reduced as compared with the first position. It can also be called a position.

Then, when the exterior portion 16 that has been displaced or removed last is returned to the original position, the second lock hole 42 and the lock pin 43 are fitted, the lock portion 40 is locked, and the slide mechanism portion 20 becomes immobile. .. As a result, even if the humanoid toy 2 is turned upside down or the posture of the arm structure 3 is changed, the forearm portion 5 is not unintentionally shortened due to the weight of the specific equipment 7 or the like.

FIG. 6 is a diagram comparing the mounted state of the specific equipment 7 due to the difference in the position of the support portion 11. The left side of FIG. 6 shows the state where the support portion 11 is in the first position, and the right side of FIG. 6 shows the state where the support portion 11 is in the second position. In the state where the support portion 11 is in the first position, even if the angle (wrist angle) of the hand portion 6 is adjusted as much as possible with the ball joint 60 (see FIG. 4), the stock 72 of the specific equipment 7 is the forearm portion. It is inevitable to interfere with 5, and the original pre-sortie pose cannot be reproduced. However, if the support portion 11 is moved to the second position, the original pre-sortie pose can be reproduced.

Equipment other than the specific equipment 7 (for example, equipment whose end is attached to the attachment recess 62 (for example, beam saber, sword, etc.), or equipment such as a pistol that has no or short rear part from the pistol grip. , Etc.), the support portion 11 may be returned from the second position to the first position.

In order to return the support portion 11 from the second position to the first position, the operation may be performed in the reverse order of the above description with reference to FIG.

Next, a more specific configuration will be described.
FIG. 7 is a front view showing a detailed configuration example of the arm structure 3 in the humanoid toy 2 of the present embodiment, and shows a state in which the support portion 11 is moved to the second position. Some parts are not shown for easy understanding of the structure.

The exterior portion 16 of the forearm portion 5 of the humanoid toy 2 is composed of a movable exterior portion 16a for lock operation and a fixed exterior portion 16b, and mainly covers the outside of the arm (the left side in FIG. 7). It is designed. The movable exterior part 16a for lock operation is one part that is convex to the outside of the arm, but the fixed exterior part 16b is composed of two front and rear pieces (meaning a two-part configuration of the front part and the back part in FIG. 7). It is composed.

The forearm base 14 is composed of two front and rear pieces (14f, 14r), and when the front and rear are combined, it forms a substantially tubular body having a slide guide 21 (see FIG. 4) and the like inside.

FIG. 8 is a front view showing a configuration example of the arm structure 3 in the humanoid toy 2 of the present embodiment, showing a state in which the movable exterior portion 16a for lock operation and the fixed exterior portion 16b are removed. FIG. 9 is a diagram showing a state in which the piece on the front side of the forearm base 14 is further removed.

The lock operation movable exterior portion 16a has a connecting portion 16c, and in the completed humanoid toy 2, the lock operation movable exterior portion 16a and the connecting portion 16c are connected and fixed to function as an integral part.

FIG. 10 is a front view showing a configuration example of the movable exterior portion 16a for lock operation and the connecting portion 16c. The connecting portion 16c is a component that engages the movable exterior portion 16a for lock operation with the slider portion 10, and slide pins 17 and slide plates 18 are projected on the front side and the back side, respectively. The slide pin 17 and the slide plate 18 are assembled so as to be loosely fitted with the guide hole 47 and the guide groove 48 formed along the direction intersecting the slide direction of the slider portion 10, respectively (see FIGS. 8 and 9). .. As a result, the movable exterior portion 16a for lock operation can be slid from the forearm portion 5 in the outward direction (on the left side when facing FIGS. 8 and 9) for the locking / unlocking operation of the lock portion 40. Basically, it does not come off from the forearm 5.

Further, a first lock hole 41 and a second lock hole 42 are recessed on the facing surface where the connecting portion 16c faces the pivot portion 12.

FIG. 11 is a front view showing a configuration example of the slider portion 10 (the pivotal branch portion 12 and the support portion 11). FIG. 12 is a perspective view of the same.

FIG. 13 is a front view of the humanoid toy 2 in a pre-sortie pose. The configuration of the present embodiment described above is applied to both the left and right arm structures 3. In FIG. 13, the support portion 11 of the arm structure 3 of the right arm is changed to the second position to equip the specific equipment 7. The support portion 11 of the left arm structure 3 remains in the first position.

As described above, according to the present embodiment, in the toy having the arm structure, it is possible to reproduce the equipment state as the original using the parts of the specific equipment without causing the reproduction of the original design to fail. More specifically, it is possible to reproduce a pose in which a relatively tall specific equipment that is equipped along the inside of a portion corresponding to the forearm is equipped along the longitudinal direction of the equipment.

The embodiment to which the present invention can be applied is not limited to the above example, and components can be added, omitted, or changed as appropriate as long as the gist of the invention is not changed.

For example, in the above embodiment, a humanoid toy has been mentioned as an example of a toy, but the present invention is not limited to a humanoid toy as long as it has a part corresponding to an arm structure such as an animal, a bird, an insect, or a crustacean. Can be applied. At that time, the name of the part corresponding to the arm structure in the above embodiment does not have to be the arm. For example, it may be a leg, a tentacle, a tail, a manipulator, and the like. In addition, at that time, the design of the hand portion 6 may be a design that does not have five fingers as long as the equipment can be attached.

Further, although the rifle is illustrated as the specific equipment 7, the design as the equipment is not limited to the firearm and can be set as appropriate.

Further, although the slide mechanism portion 20 (see FIG. 4) is exemplified as a linear motion mechanism using a focus guide, the support portion 11 protrudes from the tubular exodermis structure formed by the forearm base portion 14 and the exterior portion 16. If it can be accommodated and moved, it can be replaced with another structure. For example, it may be replaced with a bellows structure, a screw structure, or the like.

Further, although the hand portion 6 has been described as an integrally molded product having a fist shape, some movable portions may be provided. For example, it may be a hand portion having five fingers having a knuckle structure.

Further, for example, as in the hand portion 6B shown in FIG. 14, the base part 6Ba (corresponding to the five fingers and the palm portion) having the mounting recess 62 and the link portion 6Bb (corresponding to the wrist portion) having the stud 61 of the ball joint are 2 It may be a piece structure.

The link portion 6Bb has a joint cylinder portion 65 having a joint structure connected to the base part 6Ba of the hand portion 60 on one end side of the rod portion 66, and has a stud 61 (support portion 11 (see FIG. 4)) on the other end side. It has a joint structure to connect). The joint cylinder portion 65 is fitted with the joint shaft 64 of the base part 6Ba and is oscillatedly jointed. The swing axis is indicated by a long-dotted chain line in FIG.

As a result, the angle and posture of the hand portion 6B with respect to the support portion 11 can be changed. That is, the hand portion 6B can rotate the base part 6Ba in the palm direction or the opposite direction with the link portion 6Bb as a reference.

FIG. 15 is a front view showing a detailed configuration example of the arm structure 3 in the humanoid toy 2 using the hand portion 6B, and shows a state in which the support portion 11 is moved to the second position. Since the angle and posture of the hand portion 6B can be changed with respect to the support portion 11, even if the rod portion 66 is set shorter than that of the above embodiment, or the position of the stud 61 on the support portion 11 is set closer to the body side. Even if it is set to, the hand portion 6B can be set to a position and a posture suitable for equipping the specific equipment 7. That is, the humanoid toy 2 can be made to pose before the sortie as in the original.
