Description

  The present invention relates to a joint structure such as a toy doll or a mannequin doll having a movable joint, and a doll construction mechanism.

  For example, a dress-up doll generally has a moving arm and leg joint. The joint structure of a doll having such a movable joint has a structure in which the movable center of the joint coincides with the ball center. For example, the joint ends of the parts of the arms and legs or the joint members between them are pivotally supported. Or move around the fixed axis as a joint member, or move along the surface of a true spherical joint part. Things are common. Alternatively, even if the movable center of the joint is movable in a certain direction, a slit, a groove, or the like that matches the movable guide line is formed on the surface through the joint, arm, or leg portion itself. The thing is common (refer patent documents 1-4).

  However, in the case of the joint structure as described above, an unnatural gap or step (unevenness) that does not exist in the human body is formed between the joint member and the arm or leg part, or a screw hole or a straight line is formed in the joint itself. An unnatural line or gap such as a slit for passing an internal structure (rubber string, plate-like member, etc.) is formed on the outer surface of a parting line (mating surface), arm or leg. In addition, for example, when the joint is extended, the spherical shape of the joint member protrudes in an unnatural direction, or the members have an unnatural shape in advance so that the members do not interfere with each other when the joint is bent. It has an unnatural appearance that is different from the human body. As described above, the conventional joint structure has many unnatural portions as compared with the human body and lacks reality, which may impair the beauty and charm of the doll, for example.

  The present invention has been made in view of the above points, and a joint structure of a new doll that can realize an appearance closer to the human body even in various postures while ensuring the movement of the joint, and a doll that can configure the doll. It is an object to provide a configuration mechanism.

  In order to achieve the above object, the present invention provides a joint structure for a doll, which includes two doll constituent parts that form a movable joint therebetween, a connecting member, and an end that is movably fitted to the end of the connecting member. And the two doll constituent parts are slidably inserted into the inside of the other doll constituent parts, and inside each of the doll constituent parts, The fitting members are arranged, the fitting members are connected to each other by the connecting member, and at least one of the fitting members is relatively movable with respect to the doll-constituting part where the fitting member is located. In addition, the fitting member is provided with a repulsive force generating mechanism that generates a repulsive force when the two doll constituent parts move at least in a direction away from each other. In addition, when there is a fitting member that is not movable relative to the doll constituent part, the fitting member includes one fixed to the doll constituent part and one integrated with the doll constituent part. .

  According to the present invention, since one doll component part is inserted into the other doll component part, and there is a fitting member and a connecting member for connecting them inside, various internal members are not exposed on the surface as in the prior art. It is possible to reduce unnatural lines and gaps different from those of a human body, and to change the types of connecting members and fitting members without affecting the shape of the appearance, and to realize movements suitable for specific joints. In addition, since both ends of the connecting member are movably fitted to the fitting member, there are at least two movable fulcrums inside the joint, and a highly flexible joint movement can be realized. In addition, since the fitting member is movable, the movable fulcrum itself can be moved, and the degree of freedom and complicated joint movement can be realized. In addition, since the movable fulcrum is not fixed, the conventional ball center is fixed to the outer shape of the end of the one doll component and the inner shape of the other doll component into which the end is inserted. For example, a flat ellipsoidal spherical surface, an oblong ellipsoidal spherical surface, a substantially cylindrical curved surface partially having the same diameter part in the insertion direction, from the insertion direction. The cross section seen is almost an ellipsoidal shape, or a complex curved surface that draws different curved surfaces on each of the upper, lower, left, and right sides that do not have a constant spherical center or positive axis, preferably a more human-like appearance and movable trajectory It can be set to various shapes that guide In addition, by having a repulsive force generation mechanism, the repulsive force generation mechanism moves in accordance with various angles and positions (postures) of joint portions of various forms and configurations, and the repulsive force generation mechanism causes a repulsive force. Therefore, the two doll constituent parts are brought into contact (biased) with each other, and the gap between the two parts can be reduced. Therefore, it is possible to realize a doll joint having an appearance closer to that of the human body while ensuring the movement of the joint.

  The connecting member has a rod-shaped body, and has either a spherical body or a concave body at both ends of the rod-shaped body, and the fitting member is rotatably fitted to the spherical body or the concave body. May be. In such a case, it is possible to realize complicated joint movement with a high degree of freedom with simple and few members. For example, when either a concave body or a spherical body is made of a flexible material, it is easy to attach and detach, and each doll component can be easily installed and replaced.

  The rod-shaped body of the connecting member may be bent. In such a case, for example, interference between the end of the doll-constituting part and the connecting member when the joint is bent can be suppressed, so that the bending angle of the joint can be widened. Further, since the bent connecting member rotates at both end points, for example, even when the doll constituent part contacts the connecting member, the connecting member itself rotates (the bent part greatly moves), and the doll constituent part Can evacuate. As a result, it is possible to flexibly cope with various shapes and movements of the doll constituent parts.

  The outer shape of the end portion of the one doll constituent portion and / or the inner shape of the other doll constituent portion into which the end portion is inserted may be formed in a curved shape having no fixed spherical center. . In such a case, the appearance at the joint can be set closer to the human body. In such a case, the directionality and range of movement at the joint are guided or suppressed, so that movement closer to the human body can be realized. For example, when the outer shape of the end of the one doll constituent part has a substantially ellipsoidal shape that is long in the insertion direction, the one doll constituent part is drawn out from the other doll constituent part according to the angle of the joint. The other doll component can move without opening a gap. Further, when the outer shape of the end portion of the one doll constituting portion and the inner shape of the other doll constituting portion into which the end portion is inserted are formed in a substantially elliptical shape when the cross section viewed from the insertion direction is formed, The rotation around the axial direction (insertion direction) between the parts is suppressed, and movement closer to the human body can be realized at the joint.

  An angle holding force in fitting between the fitting member and the connecting member may be set larger than a repulsive force generated by the repulsive force generating mechanism. In this case, regardless of the repulsive force of the repulsive force generation mechanism, the position and angle between the one doll component and the other doll component where the end is inserted can be set to a desired state.

  The fitting portion of the fitting member of the one doll constituent part inserted into the other doll constituent part may be located inside the other doll constituent part. In this case, for example, the movement of the connecting member is not restrained by the end of the one doll component, so that a wide movable range of the connecting member can be ensured. In addition, for example, the outer peripheral surface of the one doll constituent part can be set wide, and the gap in appearance can be reduced.

  According to another aspect of the present invention, there is provided a doll joint structure, which is disposed between two doll component parts forming a movable joint, and an end portion is inserted inside the doll component part, or the end part is inserted into the doll component part. A doll component part is inserted, a joint member that is slidable with respect to the doll component part, a connecting member, and a fitting that is arranged inside each doll component part and is movably fitted to the end of the connecting member. And a fitting portion that is movably fitted to the end portion of the connecting member is formed at both ends of the joint member, and the fitting member of the one doll constituting portion and the joint member One fitting part, the other fitting part of the joint member, and the fitting member of the other doll constituting part are connected by the connecting member, and at least one of the fitting members is the fitting member. It is relatively movable with respect to the doll constituting part with the fitting The wood, repulsive force generating mechanism to generate a repulsive force may be provided when the two dolls component parts is moved in a direction at least away from each other.

  According to the present invention, since the two doll constituent parts and the joint member are inserted into each other, and there is a fitting member and a connecting member for connecting them inside, unnatural lines and gaps different from those of the human body as in the past Further, the movement suitable for a specific joint can be realized by changing the types of the connecting member and the fitting member without affecting the shape of the appearance. In addition, since both ends of each connecting member are movably fitted to each fitting member or each fitting portion, at least four movable fulcrums can be formed, and more flexible joint movement can be realized with a higher degree of freedom. it can. In addition, since the fitting member is movable, the movable fulcrum itself can be moved, and the degree of freedom and complicated joint movement can be realized. Further, since the movable fulcrum is not fixed, the outer shape of the end of the joint member, the inner shape of each doll component part into which the end part is inserted, or the outer shape of the end part of each doll component part, The inner shape of the joint member into which the end portion is inserted is not limited to a true spherical surface with a fixed spherical center as in the prior art, for example, a flat ellipsoidal spherical surface, an oblong ellipse with respect to the insertion direction A body-shaped spherical surface, a substantially cylindrical curved surface partially having the same diameter part in the middle, a substantially ellipsoidal shape whose cross section viewed from the insertion direction is close to a rhombus, or an up-down and left-right slant that does not have a constant spherical center or positive axis It can be set to a complicated curved surface that draws different curved surfaces, preferably various shapes that induce an appearance closer to the human body and a movable trajectory. In addition, by having a repulsive force generation mechanism, the repulsive force generation mechanism moves in accordance with various angles and positions (postures) of joint portions of various forms and configurations, and the repulsive force generation mechanism causes a repulsive force. Therefore, the two doll constituent parts and the joint members are brought into contact with each other (biased), and the respective gaps can be reduced. Therefore, it is possible to realize a doll joint having an appearance closer to that of the human body while ensuring the movement of the joint.

  The connecting member has a rod-shaped body, and has either a spherical body or a concave body at both ends of the rod-shaped body, and the fitting member and the fitting portion rotate to the spherical body or the concave body. The fitting may be possible. In such a case, it is possible to realize complicated joint movement with a high degree of freedom with simple and few members. Moreover, when either a concave body or a spherical body is comprised with the raw material which has flexibility, removal | desorption is also easy, and installation and replacement | exchange of each doll component part can also be performed easily.

  The outer shape of the end part of the joint member and the inner shape of the doll constituent part into which the end part is inserted, or the inner diameter of the end part of the joint member and the outer shape of the doll constituent part to be inserted into the end part , At least one of them may not be a perfect sphere, for example, may be formed in a curved shape having no fixed spherical center. In such a case, the movable directionality, range, and appearance of the joint can be set closer to the human body. For example, when the outer shape of the end portion of the joint member has a substantially ellipsoidal shape that is long in the insertion direction, the joint member and each doll component portion are spaced from each other while being pulled out from each doll component portion according to the angle of the joint. It can be moved without opening it. Further, for example, when the outer shape of the end portion of the joint member and the inner shape of the doll component portion into which the end portion is inserted are formed in a substantially elliptical shape when viewed from the insertion direction, the doll component portion Since the rotation around the axial direction (insertion direction) with the joint member is suppressed, a movement closer to the human body can be realized at the joint.

  The angle retention force in the fitting between the fitting portion of the joint member and the connecting member and the fitting between the fitting member and the connecting member may be set larger than the repulsive force generated by the repulsive force generating mechanism. . In such a case, regardless of the repulsive force of the repulsive force generation mechanism, the position and angle between one doll constituent part and the other doll constituent part sandwiching the joint member can be set to a desired state.

  The joint member may be inserted into the doll constituent part, and a fitting portion of the joint member may be located inside the doll constituent part. In such a case, for example, the movement of the connecting member is not constrained by the end of the joint member, so that a wide movable range of the connecting member can be ensured. In addition, for example, the outer peripheral surface of the one doll constituent part can be set wide, and the gap in appearance can be reduced.

  Another aspect of the present invention is a doll construction mechanism for a doll having a movable joint, which includes a connecting member and a fitting member that is movably fitted to an end of the connecting member, and the movable joint is provided on both sides. A through hole that penetrates in the longitudinal direction is formed in the doll-constituting part, and a locking portion that can lock the fitting member inserted from both sides is formed in the through hole. A repulsive force generation mechanism for connecting the fitting members on both sides is provided in the through hole of the constituent part.

  According to the present invention, since the fitting members and the connecting members for connecting them can be arranged inside the doll constituent parts, when the joints are configured by connecting the doll constituent parts and the joint members, Unnatural lines and gaps that differ from the human body can be reduced. Further, when each doll constituent part and the joint member are about to be separated from each other, the repulsive force is generated by the repulsive force generation mechanism, so that it is possible to prevent a gap from being formed between the members. Therefore, it is possible to realize a doll joint having an appearance closer to that of the human body while ensuring the movement of the joint. Moreover, the through-hole may be formed with a locking portion capable of locking the fitting member inserted from both sides. In such a case, for example, the repulsive force of each repulsive force generating mechanism is locked for each doll constituent part by the locking portion, so that it is possible to attach an appropriate appropriate repulsive force to each repulsive force generating mechanism unit. , Autonomous rotation and posture maintenance can be performed for each doll component. Also, depending on the angle (posture) of the joint, for example, when one of the doll constituent parts or the joint member tries to penetrate deeply into the other doll constituent part, the fitting member is connected to the inside of the doll constituent part. By being locked by the stopper, it is possible to prevent one of the doll constituent parts and the joint member from entering extremely deeply. In addition, even when each doll component is individually attached, detached, installed, exchanged, etc. (even when the doll component is removed singly), both fitting members that are biased toward the center are locking portions. Therefore, both the fitting members do not extremely enter the center of the doll constituting member, and each member can be installed more easily and easily. In addition, for example, a plurality of doll constituent parts can be connected in various ways to easily connect a plurality of movable joints.

  According to the present invention, it is possible to realize a doll joint having an appearance closer to that of a human body.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG.1 and FIG.2 is explanatory drawing which shows the outline of a structure of the doll 1 to which the joint structure of the doll concerning this Embodiment was applied. In addition, the aspect shown here is only one Embodiment of this invention, and this invention is not limited to this at all. For example, the configuration of one joint shown here is implemented in another joint, the relationship between the inserting side and the inserting side, the relationship between the unevenness of the fitting members, etc. are reversed, etc. Based on this, design modifications that are possible to those skilled in the art are within the scope of the present invention.

  The doll 1 has a head portion 10, a neck portion 11, a trunk portion 12, arm portions 13, and leg portions 14. The trunk 12 includes a chest 20 to which the head 10 and both arms 13 are connected, a waist 21 to which both legs 14 are connected, and an abdomen 22 between the chest 20 and the waist 21. In addition, the arm portion 13 includes an upper arm portion 30 connected to the chest portion 20, a forearm portion 31, and a hand portion 32. The leg portion 14 includes an upper knee portion 40, a lower knee portion 41, and a foot portion 42 that are connected to the waist portion 21. In the present embodiment, the chest 20 and the upper arm 30, the upper arm 30 and the forearm 31, the forearm 31 and the hand 32, the waist 21 and the upper knee 40, and the upper knee 40 as the doll constituting parts forming the movable joint. The joint structure of the doll according to the present invention is applied to the lower knee 41 and the lower knee 41 and the foot 42.

  First, the structure of the trunk | drum 12 is demonstrated. As shown in FIGS. 1 and 2, a chest internal fitting member 80 is provided above the trunk portion 12 and in the center of the hollow portion 50 of the chest portion 20. The chest internal fitting member 80 has an upper portion connected to an elastic member 83 such as rubber, and is suspended so as to be freely movable, for example. The elastic member 83 passes through the through hole 11a of the neck portion 11 located above the chest portion 20, for example, and is connected to the head portion 10 at the top thereof. Further, the lower part of the chest internal fitting member 80 is connected to the upper sphere 84 inside the abdomen 22. The upper sphere 84 is connected to a waist inner fitting member 180 having a lower sphere 86 to be described later with an elastic member 85 interposed therebetween. The upper surface of the lower sphere 86 is locked to a cylindrical locking portion 87 inside the abdomen 22 provided around the elastic member 85. Thus, the chest part 20, the abdomen part 22, and the waist part 21 are connected to each other while being urged toward the center side by the elastic member 85, thereby constituting the trunk part 12 as a whole.

  Next, the structure of the shoulder joint will be described. As shown in FIG. 3, a hollow portion 50 is formed inside the chest portion 20, and a shoulder side opening portion 51 leading to the hollow portion 50 is formed at a connection portion with the upper arm portion 30. The inner surface 51a of the shoulder-side opening 51 is formed in a curved shape so as to induce movement without hindering the rotation and entry / exit of the upper arm 30, and the outer surface 30a of the upper arm 30 inserted into the opening 51 is the chest 20 is formed in an outwardly convex curved shape so as to contact at least a part of either the inner surface 51a of the shoulder 20 or the end (edge) of the shoulder opening 51 and reduce the gap even at various positions and angles. ing. Therefore, the upper arm 30 can be rotated while moving in and out with respect to the chest 20.

  A through hole 60 is formed in the upper arm portion 30 along the longitudinal direction of the arm. A large-diameter portion 60a having a large diameter is formed at both ends of the through-hole 60, and a shoulder internal fitting member 90 and an elbow fitting member 91 are slidably disposed in the large-diameter portion 60a. The fitting members 90 and 91 may have flat surfaces formed on a part of the side surfaces so as not to rotate around the axis in the through hole 60.

  The shoulder internal fitting member 90 and the elbow fitting member 91 are connected by an elastic member 94 as a repulsive force generating mechanism that passes through the through hole 60 and is urged toward the center of the through hole 60. In addition, a locking portion 95 is formed at the boundary between the large diameter portion 60 a and the small diameter portion 60 b in the through hole 60. The engaging portion 95 can prevent both fitting members from entering the through hole 60 more than necessary. In such a case, when each doll component part is replaced or installed, each fitting member 90, 91 is conveniently placed at an appropriate position.

  The connecting member 81 has a shape in which spherical bodies 81b are formed at both ends of a rod-like body 81a. A fitting recess 92 as a fitting portion into which the spherical body 81b is rotatably fitted is formed on the surface of the shoulder inner fitting member 90 on the chest 20 side. A fitting recess 82 is formed. By connecting the fitting recesses 92 and 82 with the connecting member 81, the chest 20 and the upper arm 30 can be connected. The upper arm portion 30 can be maintained at a desired angle and position with respect to the chest portion 20 by friction of each fitting portion.

  The angle holding force in fitting between the fitting recesses 82 and 92 and the connecting member 81 is set larger than the repulsive force by the elastic member 94, and in this case, regardless of the repulsive force by the elastic member 94, the upper arm portion 30. And the chest 20 can be held at a desired angle.

  Further, the upper arm portion 30 is inserted to the back of the chest portion 20, and the fitting recess 92 is positioned inside the portion of the upper arm portion 30 inserted into the chest portion 20. In this case, since the range of the outer surface 30a of the upper arm 30 that is exposed while sliding with the chest 20 can be set wide, even when the upper arm 30 is largely bent with respect to the chest 20, a gap in appearance is difficult to be formed. Become. Further, for example, since the movement of the connecting member 81 is not restrained by the end of the upper arm portion 30, a wide movable range of the connecting member 81 can be ensured. Therefore, it is possible to secure a large movable range while reducing the gap in appearance.

  Next, the movement of the shoulder joint and the shape for guiding it will be described. When the shoulder joint is moved, the spherical bodies 81 b at both ends of the connecting member 81 rotate with respect to the fitting recesses 82 and 92. At this time, since the connecting member 81 can be rotated at two points on both ends, the shoulder 20 and the upper arm 30 can be operated in an interlocking manner, and the shoulder joint can ensure a highly flexible operation. For example, when the shoulder is greatly opened (FIG. 3B), the fitting recess 92 relatively moves in the chest 20, but the connecting member 81 can also change the angle in conjunction therewith.

  Further, the shoulder internal fitting member 90 is slidable and the elastic member 94 can be expanded and contracted, that is, the movable fulcrum of the connecting member 81 (and thus the joint part) itself is fluid and relatively movable. As a result, a larger movable range and free movement can be secured. For example, when the upper arm 30 opens and closes in the lateral direction with respect to the chest 20 (FIG. 3), or moves back and forth (such as a type that shrugs or stretches the chest) (FIG. 4), or vertically Even when the angle and the position of the chest 20 and the upper arm 30 are various, such as when the arm rotates in the plane (the arm is raised high) (FIG. 3B), the position of the fitting recess 92 is connected. The member 81 is kept in an appropriate state. As described above, various complicated operations closer to the human body can be realized.

  In addition, the shape of the shoulder joint, the dividing line, the dividing method, and the like can be set in various ways to correspond to the above operation. For example, it may have a shape that induces an appearance closer to the human body and a movable trajectory. In the present embodiment, the outer surface 30a of the upper arm portion 30 is set so as to draw an arc whose lower surface side is longer than the upper surface side when the shoulder is opened based on a substantially elliptical shape that is slightly longer in the insertion direction. Thereby, the upper arm part 30 can be widely rotated in a state where the gap between both members is reduced while being pulled out from the chest part 20. As another embodiment, each doll constituting member constituting the shoulder may be divided into a plurality of parts in order to secure a wider movable range.

  In addition, since the repulsive force is exerted by the elastic member 94, the chest 20 and the upper arm 30 are brought into contact with each other (biased) even in various postures, and the gap between the two parts can be reduced. For example, when the upper arm 30 is moved in the direction in which the upper arm 30 is pulled out from the chest 20, the upper elbow fitting member 91 is locked to the lower locking portion 95 in the upper arm 30, or the upper arm 30 is an elbow described later. The elastic member 94 generates a repulsive force in the direction in which the chest part 20 and the upper arm part 30 are brought close to each other. Further, when the upper arm portion 30 tries to enter the inside of the chest portion 20 more than intended, the shoulder internal fitting member 90 is locked by the locking portion 95 above the inner surface of the upper arm portion 30 to prevent it.

  Further, when the upper arm 30 can be inserted deeply into the chest 20 at a certain angle, both members can be easily installed at that angle. For example, when the connecting member 81 and / or each fitting part (fitting concave part 82, 92) has flexibility and is detachable, for example, the inside of the shoulder locked by the locking part 95 The upper arm 30 is simply pushed into the chest 20 by inserting the fitting recess 92 of the fitting member 90 into the spherical body 81 b that is the other end of the connecting member 81 connected to the fitting recess 82 of the chest internal fitting member 80. It becomes possible to connect.

  Next, the structure of the elbow joint will be described. As shown in FIG. 5, an elbow joint member 100 is provided between the upper arm portion 30 and the forearm portion 31. The elbow joint member 100 has a substantially ellipsoidal shape with a center line bent when viewed from the side, and both end portions are inserted into a through hole 60 of the upper arm portion 30 and a through hole 61 of the forearm portion 31 described later. ing. A part of the surface on both sides of the elbow joint member 100 that abuts on the upper arm 30 and the forearm 31 is formed in an outwardly convex curved shape that reduces the gap even at various positions and angles. The inner peripheral surface of the forearm portion 31 is also formed in a curved shape that does not prevent the elbow joint member 100 from rotating and coming in and out and that induces movement. Therefore, the upper arm part 30 and the forearm part 31 can slide along the surface of the elbow joint member 100 while drawing the entrance / exit trajectory. Further, the diameter near the center on the inner angle side of the elbow joint member 100 is small, and when the elbow joint is bent greatly (FIG. 5B), the upper arm portion 30 and the forearm portion are added to the small diameter portion 100a. The end of 31 abuts.

  A through hole 61 is formed in the forearm portion 31 along the longitudinal direction of the arm. A large diameter portion 61a is formed at an end of the through hole 61 on the elbow joint member 100 side, and the large diameter portion 61a. The under-elbow fitting member 120 is slidably disposed. In addition, the flat surface may be formed in a part of side surface of the under-elbow fitting member 120 so that it may not rotate around an axis within the through-hole 61. Further, a small diameter portion 61b is formed on the wrist joint member 140 side of the through hole 61, and the wrist upper fitting member 121 is slidably disposed in the small diameter portion 61b.

  The lower elbow fitting member 120 and the wrist upper fitting member 121 are connected by an elastic member 132 that passes through the through hole 61, and are urged toward the center of the through hole 61. At the boundary between the large diameter portion 61 a and the small diameter portion 61 b of the through hole 61, a locking portion 133 that locks the elbow fitting member 120 is formed. A cylindrical locking member 134 having a smaller diameter than the small diameter portion 61b is slidably disposed in the small diameter portion 61b. The wrist upper fitting member 121 is locked by a locking portion 135 at the end of a cylindrical locking member 134, for example.

  In addition, the cylindrical locking member 134 and the wrist upper fitting member 121 may be slidable and detachable independently of the forearm portion 31. In such a case, for example, when the diameter of the opening is narrow and the installation position of the fitting member is deep, or the distance between the engaging portions is extremely short with respect to the length of the doll component, and the elastic member installed there Even if it is difficult to install each member, such as when the length of the doll is less than the length of the doll-constituting part, it can be easily performed. For example, in FIG. 6A, the under-elbow fitting member 120 and the wrist upper fitting member 121 are respectively inserted deeply into the forearm portion 31 so that the distance between the two fitting members is a doll component part. It is set to be less than half the length of the forearm portion 31. Further, in order to generate a repulsive force, the natural length of the elastic member 132 is set to be equal to or less than the distance between the two fitting members. For example, when the stretch rate of the elastic member 132 remains at 1 to 5 times, the length of the stretched elastic member 132 is not enough for the forearm portion 31, and as a result, the elastic member 132 is pulled out from the forearm portion 31. The operation of connecting to each fitting member becomes extremely difficult. Even in such a case, if the fitting members 120 and 121 are connected to the cylindrical locking member 134 of an appropriate length in advance by the elastic member 132 and the forearm portion 31 is inserted from the wrist side later, Regardless of the length and shape of the forearm 31, the elastic member 132 having an appropriate length and elongation can be installed.

  Note that the cylindrical locking member 134 may be provided inside a doll-constituting part other than the forearm portion 31. The cylindrical locking member 134 may be made of a flexible material such as rubber. In such a case, the cylindrical locking member 134 is curved, so that it can be installed in the bent through hole 61 of the upper arm 30 as shown in FIG. It can also serve as a protective member that prevents damage due to contact with the inner wall (corner) or the like.

  Fitting recesses 110 and 111 are formed at both ends of the elbow joint member 100, a fitting recess 93 is formed in the upper elbow fitting member 91, and a fitting recess 130 is formed in the lower elbow fitting member 120. ing. The upper arm 30, the forearm 31, and the elbow joint member 100 can be connected by connecting the fitting recess 110 and the fitting recess 93, and the fitting recess 111 and the fitting recess 130 with the two connecting members 81. The upper arm portion 30 and the forearm portion 31 can be maintained at a desired angle and position with respect to the elbow joint member 100 by friction of each fitting portion.

  In addition, the angle holding force in fitting between the fitting recesses 93, 110, 111, and 130 and the connecting member 81 is set to be larger than the repulsive force by the elastic member 94 or the elastic member 132. , 132, the upper arm 30 and the forearm 31 can be held at a desired angle.

  Further, the elbow joint member 100 is inserted to the back of the upper arm portion 30 and the forearm portion 31, the fitting concave portion 110 enters the inner side of the upper arm portion 30, and the fitting concave portion 111 enters the inner side of the forearm portion 31. In such a case, since the range of the outer surface of the elbow joint member 100 that is exposed while sliding with the upper arm portion 30 and the forearm portion 31 can be set wide, the upper arm portion 30 and the forearm portion 31 are made larger than the elbow joint member 100. It becomes difficult to create a gap in appearance even when bent. Further, for example, since the movement of the connecting member 81 is not restricted by the end of the elbow joint member 100, a wide movable range of the connecting member 81 can be ensured. Therefore, it is possible to secure a large movable range while reducing the gap in appearance.

  Next, the operation of the elbow joint and the shape for guiding it will be described. When the elbow joint is moved, the spherical body 81 b of the two connecting members 81 rotates with respect to the fitting recess 93 and the fitting recess 110, and the fitting recess 111 and the fitting recess 130. At this time, since the two connecting members 81 can be rotated at a total of four points, two at each end, even if the angle between the elbow joint member 100 and the upper arm portion 30 or the forearm portion 31 is varied, it is interlocked. Correspondingly, the elbow joint can ensure a high degree of freedom of movement. For example, when the elbow of FIG. 5B is greatly bent or when the elbow of FIG. 5C is extended, the positions of the fitting recesses 110 and 111 of the elbow joint member 100 are the upper arm portion 30 and the forearm portion 31. Although the inside moves relatively, each connecting member 81 can also change the angle in conjunction. In this way, the elbow joint sandwiches the elbow joint member 100 and moves at two locations on the upper arm portion 30 side and the forearm portion 31 side, so that a larger movable range can be secured and, for example, the upper arm portion 30 and the elbow joint can be secured. In a state where the elbow is bent at the contact portion with the member 100, the doll constituting member below the forearm portion 31 including the hand portion 32 described later in the contact portion between the forearm portion 31 and the elbow joint member 100 in the axial direction. The doll constituting member below the elbow joint member 100 including the forearm portion 31 is pivoted in a state where the elbow is bent at a contact portion between the forearm portion 31 and the elbow joint member 100 (rotation of the palm, etc.) The upper arm 30 and the forearm 31 can be moved differently, such as rotating in a direction (a type in which the bent forearm is greatly shaken to the left and right), so that a more free and complex posture can be taken.

  Further, the upper elbow fitting member 91 and the lower elbow fitting member 120 are slidable and the elastic members 94 and 132 are respectively extendable, that is, the movable fulcrum of the connecting member 81 is fluid. In addition, by being relatively movable, it is possible to secure a larger movable range and free movement. For example, as shown in FIG. 5 (b), when the elbow joint member 100 is largely pulled out from the upper arm portion 30 or the forearm portion 31 and is moved outwardly (the elbow is protruded), as shown in FIG. Even if the angles and positions of the joint member 100 and the upper arm portion 30 and the forearm portion 31 are various, the positions of the fitting concave portion 93 and the fitting concave portion 130 are kept in an appropriate state with respect to the connecting member 81. As described above, various complicated operations closer to the human body can be realized.

  In addition, the shape of the elbow joint, the dividing line, the dividing method, and the like can be set in various ways to correspond to the above operation. In the present embodiment, the outer surfaces of both ends of the elbow joint member 100 are set so as to draw an arc whose back side is longer than the front side when the elbow is bent. As a result, the elbow joint member 100 is pulled out from the upper arm portion 30 and the forearm portion 31, and the upper arm portion 30 and the forearm portion 31 do not interfere with each other and rotate widely in a state where the gap between both members is reduced. Can do.

  In another embodiment, the rear surface (elbow protruding portion side) of the elbow joint member 100 may be shaped such that the upper arm portion 30 and / or the forearm portion 31 are in contact with each other. In such a case, it is possible to prevent the elbow joint from being bent in a direction that does not match the movement of the human body, such as the backward bending being restricted at the abutting portion of both members, and when the arm is extended, the rear surface portion The number of dividing lines appearing in the appearance is reduced, and the appearance is closer to the human body. Further, as another embodiment, for example, as in the case of a shoulder joint, the dividing line may be reduced by providing no joint member. In such a case, the appearance is closer to the human body.

  Further, since the repulsive force acts on the elastic members 94 and 132, the elbow joint member 100 and the upper arm portion 30 and the forearm portion 31 are in contact (biased) with each other even in various postures, thereby reducing the gaps between the portions. can do. For example, when the elbow joint member 100 moves from the upper arm portion 30 in the direction in which the elbow joint member 100 is pulled out, the shoulder inner fitting member 90 is locked to the upper locking portion 95 in the upper arm portion 30 or the upper arm portion 30 is moved to the chest portion 20. The elastic member 94 generates a repulsive force in a direction in which the upper arm 30 and the elbow joint member 100 are brought closer to each other. Further, when the elbow joint member 100 moves in the direction of being pulled out from the forearm portion 31, the wrist upper fitting member 121 is locked to a cylindrical locking member 134, or the forearm portion 31 is a wrist joint member 140 described later. The elastic member 132 generates a repulsive force in a direction in which the elbow joint member 100 and the forearm portion 31 are brought close to each other. Further, when the elbow joint member 100 tries to enter more than intended inside the upper arm portion 30 or the forearm portion 31, the upper elbow fitting member 91 is moved to the elbow side by the locking portion 95 on the elbow side of the upper arm portion 30. The lower fitting members 120 are respectively locked by the locking portions 133 of the forearm portion 31 to prevent it.

  Further, when the end of the elbow joint member 100 can be inserted deeply into the upper arm portion 30 or the forearm portion 31 at a certain angle, it is possible to easily install adjacent members at that angle. For example, when each connecting member 81 and / or each fitting portion (fitting recesses 93, 110, 111, 130) has flexibility and is detachable, first, on the upper arm portion 30 side, For example, the spherical body 81b which is the other end of the coupling member 81 connected to the fitting recess 110 of the elbow joint member 100 is moved to the fitting recess 93 of the upper elbow fitting member 91 locked by the locking portion 95. On the side of the forearm portion 31, for example, the lower elbow fitting member in which the spherical body 81 b which is the other end of the connecting member 81 connected to the fitting recess 111 of the elbow joint member 100 is locked by the locking portion 133. The elbow joint member 100 can be easily connected to the fitting recess 130 of 120 by pushing it into the upper arm portion 30 or the forearm portion 31.

  Next, the structure of the wrist joint will be described. As shown in FIGS. 5 and 6, a wrist joint member 140 is provided between the forearm portion 31 and the hand portion 32. Both ends of the wrist joint member 140 have a reduced diameter, and are inserted into the through hole 61 of the forearm portion 31 and the hollow portion 62 where the hand portion 32 is opened. The surfaces on both sides of the wrist joint member 140 that contacts the forearm portion 31 and the hand portion 32 are formed in an outwardly convex curved shape that reduces the gap even at various positions and angles, and the forearm portion 31 and the hand portion. The inner peripheral surface 32 is also formed in a curved shape that guides the movement of the wrist joint member 140. Therefore, the forearm portion 31 and the hand portion 32 can slide along the surface.

  Fitting recesses 150 and 151 are formed at both ends of the wrist joint member 140, a fitting recess 131 is formed in the wrist upper fitting member 121, and a fitting recess is formed in the hollow portion 62 of the hand portion 32. 152 is formed. The forearm portion 31, the hand portion 32, and the wrist joint member 140 can be connected by connecting the fitting recess 150 and the fitting recess 131, the fitting recess 151 and the fitting recess 152 with the two connecting members 81. The forearm portion 31 and the hand portion 32 can be maintained at a desired angle and position with respect to the wrist joint member 140 by friction of each fitting portion.

  Further, the angle holding force in the fitting between the fitting recesses 150 and 131 and the connecting member 81 is set to be larger than the repulsive force by the elastic member 132, and in this case, the wrist regardless of the repulsive force by the elastic member 132. The joint member 140 and the forearm 31 can be held at a desired angle.

  Further, the wrist joint member 140 is inserted to the back of the forearm portion 31 and the hand portion 32, the fitting recess 150 enters the inside of the forearm portion 31, and the fitting recess 151 enters the inside of the hand portion 32. In such a case, the range of the outer surface of the wrist joint member 140 that is exposed while sliding with the forearm portion 31 or the hand portion 32 can be set wide, so that the forearm portion 31 and the hand portion 32 are made larger than the wrist joint member 140. Even when bent, it becomes difficult to create a gap in appearance. Further, for example, since the movement of the connecting member 81 is not restricted by the end of the wrist joint member 140, a wide movable range of the connecting member 81 can be ensured. Therefore, it is possible to secure a large movable range while reducing the gap in appearance.

  Next, the operation of the wrist joint and the shape for guiding it will be described. When moving the wrist joint, the spherical bodies 81 b of the two connecting members 81 rotate with respect to the fitting recess 131 and the fitting recess 150, and the fitting recess 151 and the fitting recess 152. At this time, since the two connecting members 81 can be rotated at a total of four points, two at each end, even if the angle between the wrist joint member 140 and the forearm portion 31 or the hand portion 32 is varied, they are interlocked. Correspondingly, the wrist joint can ensure a high degree of freedom. For example, when the wrist of FIG. 5 (b) is largely bent toward the thumb, when the wrist of FIG. 5 (c) is largely bent toward the little finger, when the palm of FIG. 6 (b) is largely bent toward the abdominal surface, When the palm of FIG. 6 (c) is largely bent toward the back, the positions of the fitting recesses 150 and 151 of the wrist joint member 140 move relatively in the forearm portion 31 and the hand portion 32. The member 81 can change the angle in conjunction with it. In this way, the wrist joint sandwiches the wrist joint member 140 and moves at two locations on the forearm portion 31 side and the hand portion 32 side, so that a larger movable range can be secured and, for example, the palm is refracted inward. However, the forearm portion 31 side and the hand portion 32 side can be moved separately, such as rotating in the direction of the little finger, and a more free and complicated posture can be taken.

  Further, the wrist upper fitting member 121 is slidable and the elastic member 132 is extendable, that is, the movable fulcrum of the connecting member 81 is fluid and relatively movable. In addition, a large movable range and free movement can be secured. For example, as shown in FIG. 5, the wrist joint member 140 is pulled out from the forearm portion 31 and rotated in the thumb direction or the little finger direction, or as shown in FIG. 6, the wrist joint member 140 is largely rotated in the palm surface direction or the back direction. Even if the angle and position of the wrist joint member 140 and the forearm portion 31 are various, the position of the fitting recess 131 is maintained in an appropriate state with respect to the connecting member 81. As described above, various complicated operations closer to the human body can be realized.

  In addition, the shape of the wrist joint, the dividing line, the dividing method, and the like can be set in various ways to correspond to the above operation. Even if the outer shape of the end portion of the wrist joint member 140 and the inner shape of the end portion of the forearm portion 31 and the hand portion 32 into which the end portion is inserted as viewed from the insertion direction are set to have a flat elliptical shape Good. In such a case, an appearance closer to the shape of the human body can be reproduced. Further, the rotation of the hand portion 32 around the axis with respect to the forearm portion 31 is limited. Thereby, the wrist joint moves closer to the human body without rotating the wrist joint in an unintended direction. For example, in the human body, when the wrist joint including the hand part is rotated around the axis with respect to the forearm part (species for turning the palm upside down, etc.), the forearm part itself needs to be rotated (twisted). Even in the configuration, when it is desired to rotate the wrist around the longitudinal axis, as described above in the description of the elbow joint, for example, it is at the contact portion between the forearm portion 31 and the elbow joint member 100, that is, the forearm portion. You may carry out by rotation of 31.

  In addition, since a repulsive force is exerted by the elastic member 132, the forearm portion 31 and the wrist joint member 140 are brought into contact (biased) even in various postures, and the gap between the two portions can be reduced. For example, when the wrist joint member 140 is pulled out from the forearm portion 31, for example, the elbow joint member 120 is locked to the locking portion 133, or the elbow joint member 100 and the forearm portion 31 are in contact with each other. The repulsive force is generated by the elastic member 132 in the direction in which the forearm portion 31 and the wrist joint member 140 are brought close to each other. Further, when the wrist joint member 140 tries to enter the inside of the forearm portion 31 more than intended, the wrist upper fitting member 121 is locked by the locking portion 135 of the cylindrical locking member 134, prevent.

  Further, when the wrist joint member 140 can be inserted deeply into the forearm portion 31 at a certain angle, both members can be easily installed at that angle. For example, when the connecting member 81 and / or each fitting portion (the fitting recess 131, 150) has flexibility and is detachable, it is connected to the fitting recess 150 of the wrist joint member 140. The spherical joint 81b, which is the other end of the connecting member 81, is simply inserted into the fitting recess 131 of the wrist upper fitting member 121 locked by the locking portion 135 of the cylindrical locking member 134. It can be connected by being pushed into the forearm 31.

  Further, as another embodiment, for example, as in the case of a shoulder joint, the dividing line may be reduced by providing no joint member. In such a case, the appearance is closer to the human body. Alternatively, for example, an independent fitting portion into which the connecting member 81 is fitted is provided in the hollow portion 62 of the hand portion 32, and the fitting portion and the main portion of the hand portion 32 are connected by an elastic member. A configuration may be adopted. In such a case, it is possible to realize wrist rotation with a larger degree of freedom.

  Next, the structure of the hip joint will be described. For example, as shown in FIGS. 7 and 8, a hollow portion 50 is formed below the trunk portion 12 and inside the waist portion 21, and an opening portion 160 into which the upper knee portion 40 is inserted is formed below the waist portion 21. ing. The inner surface 160a of the opening 160 is formed in a curved shape so as to induce movement without hindering the rotation and entry / exit of the upper knee 40, and the outer surface 40a at the upper end of the upper knee 40 is the inner surface 160a of the waist 21 or It is in contact with at least a part of one of the end portions (edges) of the opening 160, and is formed in an outwardly convex curved shape so that the gap is reduced at various positions and angles. Therefore, the knee upper part 40 can be rotated while moving in and out with respect to the waist part 21.

  A through hole 170 is formed in the upper part of the knee 40 along the longitudinal direction of the leg. Large diameter portions 170a having large diameters are formed at both ends of the through hole 170, and a hip joint fitting member 190 and an above-knee fitting member 191 are slidably disposed in the large diameter portion 170a. Further, the hip joint fitting member 190 may be formed with a flat surface on a part of the side surface so as not to rotate around the axis in the through hole 170.

  The hip joint fitting member 190 and the above-knee fitting member 191 are connected by an elastic member 194 passing through the through hole 170 and are urged toward the center of the through hole 170. Further, a locking portion 195 is formed at the boundary between the large diameter portion 170a and the small diameter portion 170b. By this locking portion 195, it is possible to prevent the hip joint fitting member 190 and the above-knee fitting member 191 from entering the inside of the through hole 170 more than necessary.

  A waist internal fitting member 180 is provided at the center of the hollow portion 50 of the waist 21. A fitting recess 182 is formed on both the left and right sides of the waist inner fitting member 180, and a fitting recess 192 is formed in the hip joint fitting member 190. By connecting the fitting recesses 182 and 192 with the connecting member 181, the waist 21 and the upper knee 40 can be connected. The upper knee 40 can be maintained at a desired angle and position with respect to the waist 21 by friction of each fitting portion.

  The angle holding force in fitting between the fitting recesses 182 and 192 and the connecting member 181 is set to be larger than the repulsive force by the elastic member 194, and the waist 21 and the upper knee 40 regardless of the repulsive force by the elastic member 194. Can be held at a desired angle.

  For example, the connecting member 181 has a shape in which spherical bodies 181b are formed at both ends of a rod-like body 181a bent halfway. In this case, since the connecting member 181 is bent, interference between the end portion of the upper knee portion 40 on the waist 21 side and the connecting member 181 is suppressed, and the upper knee portion 40 can be bent to a wide angle accordingly. Further, since the bent connecting member 181 rotates at both end points, for example, even when the knee upper portion 40 contacts the connecting member 181, the connecting member 181 itself rotates (the bent portion moves greatly), and the knee The upper part 40 can be retracted. As a result, it is possible to flexibly cope with various shapes and movements of the upper knee 40.

  Next, the operation of the hip joint and the shape for guiding it will be described. When the hip joint is moved, the spherical bodies 181 b at both ends of the connecting member 181 rotate with respect to the fitting recesses 182 and 192. At this time, since the connecting member 181 can be rotated at two points on both ends, the hip joint can be operated in an interlocked manner even when the angles of the waist 21 and the upper knee 40 are various, and the hip joint can ensure a highly flexible operation. For example, when the knee upper part 40 in FIG. 8B is largely bent in the abdominal surface (frontal) direction, the position of the fitting recess 192 depends on the position of the waist part 21 and / or the waist part 21 and the knee upper part 40. Although the inside of the upper knee 40 moves relatively, the connecting member 181 can change the angle in conjunction with it.

  Further, the hip joint fitting member 190 is slidable and the elastic member 194 is extendable, that is, the movable fulcrum of the connecting member 181 is fluid and relatively movable. A large movable range and free movement can be secured. For example, as shown in FIG. 7B, the upper knee 40 opens and closes in the lateral direction with respect to the waist 21, or the upper knee 40 is rotated in the long axis direction as shown in FIG. When the entire leg including the ankle is directed in the lateral direction), or when rotating in the front and rear vertical plane (raising the leg upward) as shown in FIG. Even if the positions are various, the position of the fitting recess 192 is maintained in an appropriate state with respect to the connecting member 181. As described above, various complicated operations closer to the human body can be realized.

  It is also possible to set various shapes such as the shape of the hip joint, the dividing line, and the dividing method to correspond to the above operation. In the present embodiment, the outer surface 40a at the end of the upper knee 40 is set so as to draw an arc whose back side is longer than the front side when the legs are lifted. Thereby, the upper knee part 40 can be widely rotated in a state in which the gap between the two members is reduced while being pulled out from the waist part 21. As another embodiment, each doll constituting member constituting the hip joint may be divided into a plurality of parts in order to secure a wider movable range.

  In addition, since the repulsive force is exerted by the elastic member 194 as a repulsive force generating mechanism, the waist 21 and the knee upper portion 40 are abutted (biased) with each other even in various postures, and the gap between both portions can be reduced. . For example, when the knee upper part 40 moves in the direction in which the knee upper part 40 is pulled out from the lumbar part 21, the above-knee fitting member 191 is locked to the locking part 195 in the lower part of the knee upper part 40, or the knee upper part 40 is a knee joint described later. The elastic member 194 is repelled by the elastic member 194 in a direction in which the waist portion 21 and the knee upper portion 40 are brought close to each other. Further, when the knee upper portion 40 tries to enter the inside of the waist portion 21 more than intended, the hip joint fitting member 190 is locked by the locking portion 195 above the knee upper portion 40 to prevent it.

  Moreover, when the knee upper part 40 can be inserted deeply into the waist 21 at a certain angle, both members can be easily installed at that angle. For example, when the connecting member 181 and / or each fitting portion (fitting recesses 182 and 192) are flexible and detachable, the hip fitting member locked by the locking portion 195 is used. The fitting recess 192 of 190 is pushed into the spherical body 181b which is the other end of the connecting member 181 connected to the fitting recess 182 of the waist inner fitting member 180, and the knee upper part 40 is simply pushed to the waist 21 side. Can be connected.

  In this embodiment, the bent connecting member 181 is used. However, as another embodiment, for example, as shown in FIG. 8C, a bent portion is provided on the side of the fitting member 180 and the connecting member is not bent. The member 81 may be used. In such a case, a connection member common to other parts can be used, and production of the member is facilitated.

  Next, the structure of the knee joint will be described. As shown in FIG. 9, a knee joint member 200 is provided between the upper knee portion 40 and the lower knee portion 41. Both end portions of the knee joint member 200 are reduced in diameter as they approach the end portion, and are inserted into a through hole 170 in the upper knee portion 40 and a through hole 171 in the lower knee portion 41 described later. The surfaces on both sides of the knee joint member 200 that are in contact with the upper knee portion 40 and the lower knee portion 41 are formed in a curved shape that protrudes outward so that the gap is reduced at various positions and angles. The inner peripheral surface of 41 is also formed in a curved shape that does not hinder the rotation and movement of the knee joint member 200 and induces movement. Therefore, the knee upper portion 40 and the knee lower portion 41 can slide along the surface while moving in and out. Further, the diameter near the center of the inner corner side of the knee joint member 200 is small, and when the knee joint member 200 is largely bent as shown in FIG. The ends of the upper part 40 and the lower knee part 41 abut.

  As shown in FIGS. 9B and 10, a through hole 171 is formed in the lower knee 41 along the longitudinal direction of the leg. Large diameter portions 171a are formed at both ends of the through-hole 171, and the below-knee fitting member 220 and the ankle fitting member 221 are slidably disposed on the large diameter portion 171a.

  The below-knee fitting member 220 and the ankle fitting member 221 are connected by an elastic member 232 passing through the through-hole 171 and are urged toward the center of the through-hole 171. In addition, a locking portion 233 is formed at the boundary between the large diameter portion 171a and the small diameter portion 171b of the through hole 171. The locking portion 233 can prevent the under-knee fitting member 220 and the ankle fitting member 221 from entering the through hole 171 more than necessary.

  Fitting recesses 210 and 211 are formed at both ends of the knee joint member 200, a fitting recess 193 is formed at the above-knee fitting member 191, and a fitting recess 230 is formed at the below-knee fitting member 220. Yes. By connecting the fitting recess 210 and the fitting recess 193, the fitting recess 211 and the fitting recess 230 with the two connecting members 81, the upper knee portion 40, the lower knee portion 41 and the knee joint member 200 can be connected. The upper knee portion 40 and the lower knee portion 41 can be maintained at a desired angle and position with respect to the knee joint member 200 by friction of each fitting portion.

  In addition, the angle holding force in fitting between the fitting recesses 193, 210, 211, 230 and each connecting member 81 is set larger than the repulsive force by the elastic member 194 or the elastic member 232, and the elastic members 194, 232 are set. Regardless of the repulsive force, the upper knee 40 and the lower knee 41 can be held at a desired angle.

  Further, the knee joint member 200 is inserted to the back of the knee upper part 40 and the knee lower part 41, the fitting concave part 210 enters the inside of the knee upper part 40, and the fitting concave part 211 enters the inside of the knee lower part 41. In this case, since the range of the outer surface of the knee joint member 200 that is exposed while sliding with the upper knee portion 40 and the lower knee portion 41 can be set wide, the upper knee portion 40 and the lower knee portion 41 are made larger than the knee joint member 200. Even when bent, it becomes difficult to create a gap in appearance. Further, for example, since the movement of the connecting member 81 is not restricted by the end of the knee joint member 200, a wide movable range of the connecting member 81 can be ensured. Therefore, it is possible to secure a large movable range while reducing the gap in appearance.

  Moreover, as shown in FIG.9 (c), the rotation suppression part 200b which the rod-shaped body 81a of the connection member 81 contact | abuts at the both ends of the knee joint member 200 at the time of movement is formed. Thereby, the rotation of the joint member 81 in the fitting recesses 210 and 211 in a predetermined direction, for example, the forward rotation angle of the upper knee 40 and the lower knee 41 with respect to the knee joint member 200 is suppressed, and the movement of the joint in that direction is restricted. it can. In such a case, the knee joint is prevented from being bent in a direction different from the movement of the human body (for example, forward) regardless of the shape of the upper knee 40 or the lower knee 41. In another embodiment, when the front surface of the knee joint member 200 is covered with the upper knee 40 and / or the lower knee 41, the forward rotation angle is suppressed by the upper knee 40 and the lower knee. Although it is performed also by mutual contact | abutting in the front-end | tip part of 41, even if it is the case, if the rotation suppression part 200b is formed in the knee joint member 200, suppression of the rotation angle in the rotation suppression part 200b will be carried out. As a result, the upper knee 40 and the lower knee 41 are not subjected to a large load in the vicinity of the abutting portion between the front portions of the upper and lower knees 40 and 41, which are often formed of thin members. The breakage of the end portion is also reduced, which is convenient in terms of durability.

  Next, the operation of the knee joint and the shape for guiding it will be described. When moving the knee joint, the spherical body 81 b of the two connecting members 81 rotates with respect to the fitting recess 193 and the fitting recess 210, and the fitting recess 211 and the fitting recess 230. At this time, since the two connecting members 81 can rotate at a total of four points, two at each end, even if the angle between the knee joint member 200 and the knee upper part 40 or the knee lower part 41 is varied, the two coupling members 81 are interlocked. Correspondingly, the knee joint can ensure a highly flexible movement. For example, when the knee shown in FIG. 9B is greatly bent or when the knee shown in FIG. 9C is extended, the positions of the fitting recesses 210 and 211 of the knee joint member 200 are within the upper knee 40 and the lower knee 41. However, each connecting member 81 can change the angle in conjunction with it.

  Further, since the above-knee fitting member 191 and the below-knee fitting member 220 are slidable and the elastic members 194 and 232 are respectively extendable, that is, the movable fulcrum of the connecting member 81 is fluid and By being relatively movable, it is possible to secure a larger movable range and free movement. For example, as shown in FIG. 9B, when the knee joint member 200 is slightly pulled outward from the upper knee 40 or the lower knee 41 and the knee is moved outwardly (the knee is pushed out) as shown in FIG. Even if the angles and positions of the joint member 200 and the upper knee portion 40 and the lower knee portion 41 are various, the positions of the fitting recesses 193 and 230 are maintained in an appropriate state with respect to each connecting member 81. As described above, various complicated operations closer to the human body can be realized.

  In addition, the shape of the knee joint, the dividing line, the dividing method, and the like can be set in various ways to correspond to the above operation. In this embodiment, the outer surfaces of both ends of the knee joint member 200 are set so as to draw an arc whose front side is longer than the back side when the knee is bent. As a result, the knee joint member 200 is pulled out from the upper knee portion 40 and the lower knee portion 41, and the upper knee portion 40 and the lower knee portion 41 do not interfere with each other, and can rotate widely in a state where the gap between both members is reduced. it can. Further, the outer shape of the end portion of the knee joint member 200 and the inner shape of the end portions of the knee upper portion 40 and the knee lower portion 41 into which the end portions are inserted are set to have a substantially elliptical shape when viewed from the insertion direction. Also good. In such a case, an appearance closer to the shape of the human body can be reproduced. In such a case, the rotation of the knee joint member 200 around the axis with respect to the lower knee 41 and the upper knee 40 is restricted. Thereby, the movement of the knee joint closer to the human body is realized without the knee joint rotating in an unintended direction.

  Further, as described above, in another embodiment, the front surface (the knee side) of the knee joint member 200 may be shaped so as to be in contact with the upper knee portion 40 and / or the lower knee portion 41. In such a case, when the legs are extended, the number of dividing lines appearing on the front surface is reduced, and the appearance is closer to the human body. Further, as another embodiment, for example, a configuration without a joint member may be used similarly to a shoulder joint or the like, and the dividing line may be reduced. In such a case, an appearance closer to a human body is obtained.

  Further, since the repulsive force acts on the elastic members 194 and 232, the knee joint member 200 and the upper knee 40 and the lower knee 41 are brought into contact with each other (biased) even in various postures, thereby reducing the gaps between the respective parts. can do. For example, when the knee joint member 200 moves in the direction in which the knee joint member 200 is pulled out from the knee upper part 40, the hip joint fitting member 190 is locked to the upper locking part 195 in the knee upper part 40 or the knee upper part 40 is connected to the waist part 21. The elastic member 194 generates a repulsive force in the direction in which the upper knee portion 40 and the knee joint member 200 are brought closer to each other. When the lower knee 41 moves away from the knee joint member 200, the in-ankle fitting member 221 is locked to the lower locking portion 233 in the lower knee 41 or the lower knee 41 is a foot described later. The elastic member 232 generates a repulsive force in the direction in which the lower knee portion 41 and the knee joint member 200 are brought closer to each other. Further, when the knee joint member 200 tries to enter the inside of the upper knee 40 or the lower knee 41 more than intended, the above-knee fitting member 191 is moved below the knee by the locking portion 195 on the knee side of the above knee 40. The fitting members 220 are locked by the locking portions 233 on the knee side of the lower knee 41 to prevent it.

  Further, when the end portion of the knee joint member 200 can be inserted deeply into the upper knee portion 40 or the lower knee portion 41 at a certain angle, it is possible to easily install adjacent members at that angle. For example, when each connecting member 81 and / or each fitting portion (fitting recesses 193, 210, 211, 230) has flexibility and is detachable, first, on the upper knee 40 side, For example, the spherical body 81b which is the other end of the coupling member 81 connected to the fitting recess 210 of the knee joint member 200 is moved to the fitting recess 193 of the above-knee fitting member 191 locked by the locking portion 195. Further, for example, on the knee lower portion 41 side, the spherical body 81 b that is the other end of the connecting member 81 connected to the fitting recess 211 of the knee joint member 200 is locked by the locking portion 233. It is possible to connect to the fitting recess 230 by simply pushing the knee joint member 200 into the upper knee portion 40 or the lower knee portion 41.

  Next, the structure of the ankle joint will be described. For example, as shown in FIGS. 10 and 11, a hollow portion 172 is formed inside the foot portion 42, and an opening portion into which the knee lower portion 41 is inserted is formed above the hollow portion 172. The inner surface 42a of the opening is formed in a curved shape that does not hinder the rotation of the lower knee 41 and induces movement, and the outer surface 41a at the lower end of the lower knee 41 is the inner surface 42a of the foot 42 or the opening. It is formed in a curved shape so as to abut against at least a part of one of the end portions (edges) of the portion and reduce the gap even at various positions and angles. Accordingly, the foot portion 42 can slide along the surface while moving in and out.

  The hollow portion 172 of the foot portion 42 is provided with a foot portion fitting member 240 fixed to the foot portion 42, and a fitting recess 241 is formed on the upper portion of the foot portion fitting member 240. Further, a fitting recess 231 is formed in the ankle fitting member 221. By connecting the fitting recesses 231 and 241 with the connecting member 81, the lower knee portion 41 and the foot portion 42 can be connected. The foot part 42 can be maintained at a desired angle and position with respect to the lower knee 41 by friction of each fitting part.

  The angle holding force in fitting between the fitting recesses 231 and 241 and the connecting member 81 is set to be larger than the repulsive force by the elastic member 232, and regardless of the repulsive force by the elastic member 232, 42 can be held at a desired angle.

  The foot fitting member 240 is fixed to a sole 242 that can be removed from the foot 42 main body, and the foot fitting member 240 and the sole 242 are inserted into the foot 42 from the bottom of the foot. It may be locked and detachable. For example, the shape seen from the side surfaces of the sole part 242 and the foot fitting member 240 is an area of the lower surface that is recessed near the center so that the end of the knee lower part 41 does not interfere when the ankle joint is moved. Has a substantially trapezoidal shape, and the contact portion of the foot portion 42 main body with the sole portion 242 and the foot portion fitting member 240 is formed in a shape capable of locking it. Thereby, the foot sole part 242 and the foot part fitting member 240 can be removed from the back surface of the foot part 42. In this case, for example, it can be easily replaced with various soles 242 and the like which are set to be easily fixed to a doll base or shoes. As another embodiment, for example, the foot sole 242 is not removable from the foot 42 main body, and may be formed continuously. In such a case, the dividing lines on the appearance are reduced and the appearance is closer to the human body.

  A fitting recess 243 is provided at the front portion of the foot fitting member 240. An intermediate member 244 is provided on the front side of the foot fitting member 240. A spherical portion 245 is formed at the rear portion of the intermediate member 244, and a fitting recess 246 is formed at the front portion of the intermediate member 244. The spherical portion 245 of the intermediate member 244 is fitted in the fitting recess 243 of the foot fitting member 240. An opening 250 is formed on the distal end side of the foot portion 42. A toe 251 is inserted into the opening 250. A fitting recess 252 is formed in the toe portion 251, and the fitting recess 252 and the fitting recess 246 are connected by a connecting member 81. Thereby, the toe part 251 can be connected and bent with respect to the foot part 42.

  The spherical bodies 81b of the connecting member 81 rotate with respect to the fitting recess 246 of the intermediate member 244 and the fitting recess 252 of the toe 251 so that the toe 251 bends in a desired direction with respect to the foot 42. It is done. At this time, since the connecting member 81 can be rotated at two points on both ends, the toe joint 251 can be operated in conjunction with various angles of the toe part 251 with respect to the foot part 42 body, and the toe joint operates with a high degree of freedom. Can be secured.

  The toe part 251 may be divided into a plurality of parts. In this embodiment, the thumb and the other four fingers are divided as separate members. In such a case, since the finger part is independently movable, it is convenient for the case where the doll is made stable and independent. Moreover, the toe part 251 may be installed so that attachment or detachment with the intermediate member 244 is possible. In such a case, it can be exchanged with or removed from the toes 251 of an appropriate size, which is convenient when, for example, it is desired to wear smaller shoes. As another embodiment, for example, the intermediate member 244 may be divided and formed, and the divided members may be connected by an elastic member. In such a case, the toe can be turned with a larger degree of freedom.

  Next, the operation of the ankle joint and the shape for guiding it will be described. When the ankle joint is moved, the spherical bodies 81 b at both ends of the connecting member 81 rotate with respect to the fitting recesses 231 and 241. At this time, since the connecting member 81 can be rotated at two points on both ends, even if the angles of the knee lower part 41 and the foot part 42 are varied, the ankle joint can ensure a highly flexible operation. . For example, when the ankle is greatly extended (FIG. 10C), the fitting recess 241 relatively moves in the lower knee 41, but the connecting member 81 can also change the angle in conjunction with it.

  Further, the ankle fitting member 221 is slidable and the elastic member 232 is extendable, that is, the movable fulcrum of the connecting member 81 is fluid and relatively movable. In addition, a large movable range and free movement can be secured. For example, when the lower knee portion 41 is pulled out from the foot portion 42, the foot portion 42 rotates in the front-rear vertical plane with respect to the lower knee portion 41 (FIG. 10), or in the left-right vertical plane (FIG. 11). ) And the like, even if the angles and positions of the knee lower part 41 and the foot part 42 are various, the position of the fitting recess 231 is maintained in an appropriate state with respect to the connecting member 81. As described above, various complicated operations closer to the human body can be realized.

  In addition, the shape of the ankle joint, the dividing line, the dividing method, and the like can be set in various ways to correspond to the above operation. For example, the cross section viewed from the insertion direction of the outer shape 41a of the lower knee 41 and the inner surface 42a of the foot portion 42 into which the end portion is inserted may be set to a substantially elliptical shape close to a rhombus. In such a case, an appearance closer to the shape of the human body can be reproduced. In such a case, the rotation of the foot 42 around the axis with respect to the lower knee 41 is restricted. Thereby, the movement of the ankle joint closer to the human body is realized without the ankle joint rotating in an unintended direction. In particular, it is advantageous from the viewpoint of maintaining the posture that the rotation in the unintended direction is suppressed at the ankle joint, which is the portion where the weight of the entire doll 1 is the most. For example, in a human body, when the ankle joint including the foot is largely rotated around the longitudinal axis of the leg while the sole is in contact with the ground, the entire leg is required to rotate. Even in this configuration, the movement may be performed at the contact portion between the knee upper portion 40 and the waist 21 as described above, that is, by the rotation of the knee upper portion 40. As another embodiment, for example, in order to secure a wider movable range, each doll constituting member constituting the ankle may be divided into a plurality of parts.

  In the present embodiment, the contact portions of the knee joint member 200 with the upper knee portion 40 and the lower knee portion 41 are set in a shape in which the rotation in the axial direction is suppressed. However, as another embodiment, You may set a contact part in the shape which does not suppress rotation. In such a case, the leg portion 42, the lower knee portion 41, and the knee joint member 200 can be rotated around the longitudinal axis of the leg regardless of the rotation at the contact portion between the upper knee portion 40 and the waist portion 21. For example, when it is difficult to rotate the upper knee 40 around the axis due to the shape of the contact portion between the upper knee 40 and the waist 21, the rotation around the axis can be compensated.

  Further, since a repulsive force is exerted by the elastic member 232, the lower knee 41 and the foot 42 are brought into contact (biased) even in various postures, and the gap between the two parts can be reduced. For example, when the knee lower part 41 moves in the direction of being pulled out from the foot part 42, the lower knee fitting member 220 is locked to the upper locking part 233 in the lower knee part 41, or the lower knee part 41 is connected to the joint member 200. The elastic member 232 generates a repulsive force in a direction in which the lower knee portion 41 and the foot portion 42 are brought closer to each other. Further, when the lower knee 41 tries to enter the inside of the foot portion 42 more than intended, the in-ankle fitting member 221 is locked by the lower locking portion 233 in the lower knee portion 41 to prevent it.

  Further, when the lower knee 41 can be inserted deeply into the foot portion 42 at a certain angle, both members can be easily installed at that angle. For example, when the connecting member 81 and / or each fitting portion (the fitting recesses 231 and 241) have flexibility and can be detached, the connection member 81 and the fitting recess 241 of the foot fitting member 240 are connected. The spherical body 81b, which is the other end of the connecting member 81, is pushed into the fitting recess 231 of the in-ankle fitting member 221 locked by the locking portion 233, and the knee lower portion 41 is simply pushed into the foot portion 42. Can be connected.

  In addition, since the repulsive force of each repulsive force generating mechanism is locked for each doll component part, this mechanism can change the repulsive force generating mechanism to give an appropriate appropriate repulsive force strength. Can be autonomously rotated and maintained in posture for each doll component. For example, at the wrist joint, which is a part that frequently changes poses, the repulsive force of the elastic member 132 is weakened so that it can be easily moved, and the weight of the entire leg is prevented so that the gap does not open when the doll 1 is lifted by grasping the abdomen 22. Depending on the setting of the posture at the time of display, such as when the repulsive force of the elastic member 232 is increased to increase the strength of the ankle joint, when increasing the repulsive force at the hip joint or when the doll 1 is displayed independently, The strength of the repulsive force at each joint site can also be changed.

  According to the above embodiment, for example, in the joint structure of the shoulder joint, the connecting member 81 and the fitting members 80 and 90 into which the end portions of the connecting member 81 are movably fitted are provided. Are slidably inserted inside the chest part 20, and fitting members 80 and 90 are arranged inside the upper arm part 30 and the chest part 20, and the fitting members 80 and 90 are connected to each other by a connecting member 81. The fitting member 90 is slidable relative to the upper arm portion 30, and the fitting member 90 is elastic so as to generate a repulsive force at least when the upper arm portion 90 moves in the direction of being pulled out from the chest portion 20. A member 94 is connected. Further, the joint structure of the hip joint includes a connecting member 181, fitting members 180 and 190, an elastic member 194, and the like, and has substantially the same configuration. Furthermore, the joint structure of the ankle joint includes the connecting member 81, the fitting members 221, 240, the elastic member 232, and the like, and has substantially the same configuration.

  According to this configuration of the present embodiment, one doll constituent part (upper arm 30, upper knee 40, lower knee 41, etc.) forming a movable joint is the other doll constituent part (chest 20, waist 21, foot). 42), and there are fitting members and connecting members that connect them inside, so as shown in FIG. 12, unnatural lines and gaps different from a human body like a conventional doll can be reduced, In addition, the movement suitable for a specific joint can be realized by changing the types of the connecting member and the fitting member without affecting the appearance shape. In addition, since both ends of the connecting member are movably fitted with the fitting member, at least two movable fulcrums can be formed, and a complicated joint movement with high flexibility can be realized. Further, since the fitting member is movable, the movable fulcrum itself can be moved, and the degree of freedom and complicated joint movement can be realized. In addition, since the movable fulcrum is not fixed, the outer shape of the end of the one doll constituent part and the inner shape of the other doll constituent part into which the end is inserted are Not only a spherical spherical surface, but also various shapes that are suitable for each joint part and that induce an appearance close to a human body and a movable locus can be set. Furthermore, by having an elastic member as a repulsive force generation mechanism, for example, various angles and angles of joint portions in various forms and configurations, such as an aspect in which one inserted doll component is pulled out from the other doll component Depending on the position (posture), the elastic member extends in cooperation and a repulsive force acts, so that the two doll constituent parts are brought into contact with each other (biased), and the gap between the two parts can be reduced. Therefore, it is possible to realize a doll joint having an appearance closer to that of the human body while ensuring the movement of the joint.

  The connecting members 81 and 181 have rod-shaped bodies 81a and 181a and spherical bodies 81b and 181b at both ends of the rod-shaped bodies 81a and 181a, and the fitting members are pivotally fitted to the spherical bodies 81b and 181b. Therefore, it is possible to realize complicated joint movement with a high degree of freedom with simple and few members. Further, when the spherical body and / or the fitting member are made of a flexible material, the attachment and detachment can be facilitated, and the installation and replacement of the doll constituent parts can be easily performed. Note that both ends of the connecting member do not necessarily have to be spherical, and may be concave. In this case, the fitting member is rotatably fitted to the concave.

  For example, in the hip joint, since the rod-shaped body 181a of the connecting member 181 is bent, for example, the interference between the end of the upper knee 40 and the connecting member 181 when the joint is bent can be suppressed, and the bending angle of the hip joint is widened. Can do. Further, since the bent connecting member 181 rotates at both end points, for example, when the end of the knee upper portion 40 comes into contact with the connecting member 181, the bent portion of the connecting member 181 also rotates greatly and retracts from the upper knee 40. be able to. As a result, it is possible to flexibly cope with various shapes and movements of the upper knee 40.

  According to the present embodiment, the outer shape of the end of the one doll component (upper arm 30, upper knee 40, lower knee 41, etc.) and / or the other doll configuration into which the end is inserted. The inner shape of the part (chest 20, waist 21, foot 42, etc.) is formed in a curved shape that does not have a constant spherical center. In such a case, the appearance of the joint can be set closer to the human body. In such a case, since the directionality and range of movement at the joint are guided or suppressed, movement closer to the human body can be realized. For example, when the outer shape of the end of the one doll constituent part has a substantially ellipsoidal shape that is long in the insertion direction, the one doll constituent part is drawn out from the other doll constituent part according to the angle of the joint. The other doll component can move without opening a gap. Further, when the outer shape of the end portion of the one doll component part and the inner shape of the other doll component part into which the end part is inserted are formed in a substantially elliptical shape when viewed from the insertion direction, The rotation of the doll constituent parts around the axial direction (insertion direction) is suppressed, and a movement closer to the human body can be realized at the joint.

  In addition, the connection member 81 and the fitting recesses 82 and 92 in the shoulder joint, the connection member 181 and the fitting recesses 182 and 192 in the hip joint, the connection member 81 and the fitting recess 231 in the ankle joint, Since the angle holding force due to the engagement with the elastic member 241 is set to be larger than the repulsive force due to the elastic members 94, 194, 232, one doll constituting portion and the end portion thereof regardless of the repulsive force due to the elastic member It is possible to set the position and angle with other doll constituent parts into which the is inserted into a desired state.

  In the above embodiment, the joint structure is used for a shoulder joint, a hip joint, and an ankle joint, but may be used for other joints such as an elbow joint, a wrist joint, and a knee joint.

  In the elbow joint of the present embodiment, for example, the elbow joint member 100 is arranged between the upper arm portion 30 and the forearm portion 31 and the end portion is slidably inserted into the upper arm portion 30 and the forearm portion 31. The member 81 has fitting members 91 and 120 which are disposed inside the upper arm portion 30 and the forearm portion 31 and into which end portions of the connecting member 81 are movably fitted, and are connected to both ends of the elbow joint member 100. Fitting recesses 110 and 111 into which end portions of the member 81 are movably fitted are formed, the fitting member 91 and the fitting recess 110, the fitting recess 111 and the fitting member 120 are connected by two connecting members 81, The fitting members 91 and 120 are slidable relative to the upper arm portion 30 and the forearm portion 31 with the fitting member, and the fitting members 91 and 120 include at least the upper arm portion 30 and the forearm portion 31. The elbow joint member 100 is pulled out from Elastic members 94,132 to produce a repulsive force when moving is connected to a direction. The knee joint also has a substantially similar configuration including the knee joint member 200 and the like. In this embodiment of the wrist joint, the wrist joint member 140 has a substantially similar configuration on the forearm portion 31 side.

  According to this configuration of the present embodiment, the joint members (the elbow joint member 100, the knee joint member 200, and the wrist joint member 140) have two doll constituent parts (the upper arm portion 30 and the forearm portion 31, the upper knee portion 40). Lower knee 41, forearm portion 31 and hand portion 32), and there are fitting members and connecting members that connect them inside, reducing unnatural lines and gaps different from those of the human body as in the past In addition, the movement suitable for a specific joint can be realized by changing the types of the connecting member and the fitting member without affecting the appearance shape. In addition, since both ends of each connecting member are movably fitted to each fitting member or each fitting portion, at least four movable fulcrums can be formed, and more flexible joint movement can be realized with a higher degree of freedom. it can. Further, since the fitting member is movable, the movable fulcrum itself can be moved, and the degree of freedom and complicated joint movement can be realized. In addition, since the movable fulcrum is not fixed, the outer shape of the end portion of the joint member and the inner shape of each doll component part into which the end portion is inserted are limited to a true spherical surface with a fixed ball center. Instead, it can be set to various shapes that guide the appearance and the movable locus closer to the human body. Further, by having the repulsive force generation mechanism, the repulsive force generation mechanism extends in cooperation with each other according to various angles (postures) of the joints having various forms and configurations, and the repulsive force is generated by the repulsive force generation mechanism. Therefore, the two doll constituent parts and the joint members are brought into contact with each other (biased), and the respective gaps can be reduced. Therefore, it is possible to realize a doll joint having an appearance closer to that of the human body while ensuring the movement of the joint.

  In addition, each doll component and the joint member are connected by a connecting member having a spherical body and a fitting member into which the spherical body is rotatably fitted. Therefore, a simple and simple configuration with a high degree of freedom and complexity. Can move the joint.

  In addition, the angle holding force in fitting between each connecting member 81 in the elbow joint and the fitting recesses 93 and 110 and fitting in the fitting recesses 111 and 130 is set larger than the repulsive force by the elastic members 94 and 132, respectively. In addition, the angle holding force due to the fitting between the coupling members 81 and the fitting recesses 193 and 210 and the fitting recesses 211 and 230 in the knee joint is set larger than the repulsive force due to the elastic members 194 and 232, respectively. In addition, since the angle holding force due to the fitting between the connecting member 81 and the fitting recesses 131 and 150 in the wrist joint is set to be larger than the repulsive force due to the elastic member 132, each joint can be connected regardless of the repulsive force due to the elastic member. The position and angle between the member and each doll component part into which the end is inserted can be set to a desired state.

  For example, the fitting recesses 110 and 111 of the elbow joint member 100 are located inside the upper arm portion 30 and the forearm portion 31, and the fitting recesses 210 and 211 of the knee joint member 200 are located inside the upper knee portion 40 and the lower knee portion 41. The fitting recesses 150 and 151 of the wrist joint member 140 are located inside the forearm portion 31 and the hand portion 32. For this reason, for example, the movement of the connecting member 81 is not restricted by the end of the joint member, and a wide movable range of the connecting member 81 can be ensured. In addition, for example, the outer peripheral surface of the joint member can be set wide, and the gap in appearance can be reduced.

  In the above embodiment, the joint member is used for an elbow joint, a wrist joint, and a knee joint that require a relatively wide bending angle, so that the gap between the doll components is sufficiently secured while ensuring a sufficient bending angle of the joint. Can be reduced. The joint member may also be used for other joints such as a shoulder joint other than the elbow joint, wrist joint, and knee joint, hip joint, and ankle joint.

  Further, in the doll construction mechanism that constitutes the doll 1 having the movable joint in the present embodiment, for example, the upper arm portion 30 on which the movable joint is formed on both sides, the connecting member 81, and the end of the connecting member 81 are movably fitted. The upper arm 30 is formed with a through-hole 60 penetrating in the longitudinal direction, and the through-hole 60 has fitting members 90 and 91 inserted from both sides. A locking portion 95 that can be locked is formed, and the through hole 60 is provided with an elastic member 94 that connects the fitting members 90 and 91 on both sides. The forearm 31, the upper knee 40, the lower knee 41 and the like have the same configuration.

  According to the present embodiment, since the fitting members and the connecting members that connect them can be arranged inside the doll constituent parts, when the joints are configured by connecting the doll constituent parts and the joint members, Such unnatural lines and gaps that are different from the human body can be reduced. Further, when each doll constituent part and the joint member are about to be separated from each other, the repulsive force is generated by the repulsive force generation mechanism, so that it is possible to prevent a gap from being formed between the members. Therefore, it is possible to realize a doll joint having an appearance closer to that of the human body while ensuring the movement of the joint. The through hole is formed with a locking portion that can lock the fitting member inserted from both sides. Thereby, for example, since the repulsive force of each repulsive force generating mechanism is locked for each doll constituent part by the locking portion, it becomes possible to attach an appropriate repulsive force level independently to each repulsive force generating mechanism unit. , Autonomous rotation and posture maintenance can be performed for each doll component. Also, depending on the angle (posture) of the joint, for example, when one of the doll constituent parts or the joint member tries to penetrate deeply into the other doll constituent part, the fitting member is connected to the inside of the doll constituent part. By being locked by the stopper, it is possible to prevent one of the doll constituent parts and the joint member from entering extremely deeply. Further, even when each doll component is individually removed, installed, exchanged, etc., since both fitting members urged toward the center are locked by the locking portions, both fitting members are dolls. Each member can be installed more easily and easily without extremely entering the center of the component member. In addition, for example, a plurality of doll constituent parts can be connected in various ways to easily connect a plurality of movable joints.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, in the above embodiment, the connecting member 181 bent at the hip joint is used, but a linear connecting member 81 may be used. Moreover, you may use the connection member 181 for another joint. For example, the connecting member may have other shapes such as a shape in which both end portions are not spherical, a rod-shaped body as a whole, a rod-shaped body having a rotating portion, and a plurality of rotating portions. Good.

  In addition, a part or the whole of the relationship between the above-described connecting member and the unevenness of the fitting member or the fitting portion may be reversed. For example, both ends or one end of the connecting member may be formed into a concave body, and the corresponding fitting member or fitting portion side may be formed into a spherical body. Further, a plurality of connecting members may be provided in one connecting portion in parallel and / or in series, asymmetrical in the vertical and horizontal directions.

  Moreover, the elastic member does not necessarily have to penetrate through the through hole of the doll component, and a bottomed hole may be formed from both ends of the doll component and may be provided in the bottomed hole, respectively. That is, the elastic member may be divided within the doll component. Further, the repulsive force generation mechanism is not limited to an elastic member, and may be a spring or the like, a cylinder or the like that can be electrically and mechanically compressed as long as it generates a repulsive force. Further, the repulsive force generated by the repulsive force generation mechanism may be generated when the two doll constituent parts move at least in the direction away from each other, and may occur when the two doll constituent parts do not move in the direction away from each other. It does not have to occur.

  The joint structure of the above embodiment may be applied to the joints when joints are provided in other parts such as the neck, trunk, head, and fingers of the doll. Moreover, in the above embodiment, although the both ends of the joint member were inserted in the doll constituent part, the end part of the doll constituent part may be inserted in the both ends of the joint member. In addition, one end of the joint member may be inserted into the doll constituent part, and the doll constituent part may be inserted into the other end of the joint member. In addition, the curved surface with which each doll component part abuts may be spherical.

  In addition, the size, material, etc. of the doll constituent parts, joint members, fitting members, etc. are not limited. For example, the doll constituent part, the joint member, etc. may be a material having plasticity or flexibility. The doll may be a mannequin, a prosthetic limb, a robot, or the like, and may be an animal, an insect, or a living / inanimate object as long as it has a similar joint structure.
