Description

The present invention relates to a joint of a doll, and more particularly to a joint portion disposed in the middle of a rod-like member extending from the trunk.
In this specification, a doll is a doll that has a torso, legs, arms, and head, and that replicates the body shape of a creature such as a human being or an animal. The concept includes not only a head but also a so-called doll body. Moreover, all the so-called movable dolls in which required portions such as limbs and waist are configured to be movable are targeted. In addition, movable dolls are provided with joints separately at the required movable locations, or are formed integrally without any joints, but can be bent at the required locations such as knees and elbows. All known ones are targeted.
In addition, the “torso” is a portion excluding the doll's arms, legs, and head, but in this specification, the torso is a concept including a head, and the “rod-like member” is attached to the torso by protruding. It is a concept including all members attached to projecting from the trunk, such as the tail and other antennas, in a rod shape.
Further, the “upper leg” refers to the range from the base of the leg (the connecting portion with the lumbar crotch position) to the upper knee, and the “lower leg” refers to the range from the lower knee to the ankle.

In the recent doll industry, dolls having a configuration that faithfully replicates the human body (naked body) form called a figure are gaining popularity among customers.
The figure dolls are generally played by girls and the like, or simply dressed up, but the figure consumer base has changed recently, especially for male and female adults. The number of people is also increasing. Also, create a custom doll called a custom doll with a head of your choice on the doll body and various costumes, and pose the doll to publish the photographed image. The way of playing is being recognized.
Such enthusiasts place an emphasis on posing, and tend to desire arm and leg joints to move realistically like humans, especially those who place an emphasis on posing in a deeper expression In order to do this, the degree of freedom of the movable range of the arms and elbows is regarded as important. In particular, whether or not the joints of the arms and knees can be bent at an acute angle has become a serious concern.

Conventionally, a spherical joint is well known as an elbow joint of a doll's arm or a knee joint of a leg. For example, the joint structure of a knee joint is composed of a pair of hemispherical joints, and the joints are an upper leg and a lower leg. One hemispherical joint has a rotation axis at the center of the circular plane, and the rotation axis can slide on the circular plane of the other hemispherical joint. The circular flat centers are connected to each other by a rotation shaft so that the upper leg and the lower leg can be bent and rotated about the rotation axis.
Since the upper leg and the lower leg are rotated about the rotation axis regardless of the bending position, the spherical joint portion can always maintain a spherical appearance, and the upper and lower legs of the doll are Since it is connected with a spherical body, there is an advantage that the appearance of the leg portion looks beautiful.
However, when the spherical joint is bent, the lower leg rear surface of the upper leg and the upper leg rear surface of the upper leg are brought into contact with each other at a position where the upper leg and the lower leg are bent by about 90 degrees to inhibit further bending. . Therefore, there is a disadvantage that the bending angle when the rear surface of the lower leg portion of the upper leg and the rear surface of the upper leg portion of the lower leg are in contact is the maximum bending angle, and as a result, the leg portion of the doll is bent more than the maximum bending angle. There was a problem that the position of the doll could not be given and the posing of the doll was restricted.

As a technical solution for solving the above drawbacks and increasing the flexion angle of the elbow and knee joints, the present inventor has disclosed a double joint part provided in a knee joint part of a leg as disclosed in Patent Document 1. Is provided.
In the double joint portion of Patent Document 1, a knee body having disk-like connecting pieces at both ends is connected to a bifurcated holding portion at the lower end of the upper leg and a holding portion at the upper end of the lower leg. The knee body is configured to be movably coupled, and the knee body can bend the knee joint by rotating the shaft coupling portions at both ends. In the double joint having such a configuration, the rotation center of the shaft coupling portion on the lower leg side is such that the shaft coupling portion on the upper leg side and the shaft coupling portion on the lower leg side from the rotation center of the shaft coupling portion on the upper leg side. Rotate with the position separated by the distance as the center of rotation. Therefore, when the shaft coupling portion on the upper leg side of the knee body is bent by approximately 90 degrees, the shaft coupling portion on the lower leg side bends behind the knee, so that the lower end of the rear surface of the upper leg and the lower leg are compared with the spherical joint described above. It becomes difficult for the upper end of the rear surface to come into contact, and a large maximum bending angle can be obtained.
JP 2004-121494 A

The outer diameter of the upper leg shaft 51 is slightly smaller than the inner diameter of the inner hole 43a provided in the cylindrical portion 43 of the fan-shaped member 4 (see the dimension R2 in FIGS. 4B and 4D). A screw hole 51 a is formed in the length direction of the upper leg shaft 51 on the distal end side of the upper leg shaft 51.

The pin 52 is a region close to the outer periphery 54 of the semicircular portion 54a, and is rotated backward from the perpendicular 58 passing through the center of the upper leg shaft 51 in the backward direction at a predetermined angle θ1 (left direction in FIG. 5A). ) To a length D5 that can be inserted into the circumferential groove 25 of the upper leg side connecting plate 22. In this embodiment, as the length dimension D5, from the edge 54 (semi-circular part 54a), the thickness dimension D3 of the lower leg side connecting plate 33, the thickness dimension D1 of the upper leg side connecting plate 22, and the thickness of the lower leg side connecting plate 33 are used. The total length of the dimension D3 is set.
Note that the predetermined angle θ1 is set to approximately 55 degrees in the present embodiment. This angle θ1 is set to the same angle as the angle range θ1 in which the circumferential groove 25 of the upper leg side connecting plate 22 is formed. Therefore, when the angle range θ1 in which the circumferential groove 25 is formed is changed in design, the angle θ1 in which the pin 52 is formed is also changed in design according to the changed angle range.
The diameter of the pin 52 is set to be smaller than the connecting groove 22 radial groove width of the circumferential groove 25.

  The lower leg shaft 53 is provided at the arc center of the arc portion 54b, and the arc center is a region close to the outer periphery 54 of the semicircular portion 54a and is clockwise from a perpendicular 58 passing through the center of the upper leg shaft 51. It is located in the rearward direction (left direction in FIG. 5A) of the predetermined angle θ2. As the predetermined angle θ2, approximately 75 degrees is set in this embodiment. This angle θ2 is set to the same angle as a predetermined angle θ2 at which the lower leg shaft 45 of the fan-shaped member 4 is formed. Therefore, when the angle θ2 at which the lower leg shaft 45 is formed is changed in design, the angle θ2 at which the lower leg shaft 53 is formed is also changed in design according to the changed angle.

Further, a region in the vicinity of the lower leg shaft 53 of the semicircular portion 54a of the edge portion 54 and a rear end portion 54c have dimensions corresponding to the thickness of the lower leg side connecting plate 32 (see dimension D3 in FIG. 3B). A step 54d and a step 54e are formed at the boundary between the edge portion 54 and the non-notched portion of the edge portion 54, which are notched toward the outer surface direction (left side in FIG. 5B).
The lower leg shaft 53 extends from the notch and protrudes to the same length (see dimension D3 in FIG. 5) as the thickness of the lower leg side connecting plate 32 (see dimension D3 in FIG. 3 (b)). To do.
The diameter of the lower leg shaft 53 is slightly smaller than the diameter of the shaft hole 39a of the lower leg side connecting plate 32.
The shape of the outer surface 55 of the cover portion 5 is formed so as to protrude from the edge portion 54 (semi-circular portion 54a, arc portion 54b, and rear end portion 54c) with a smoothly convex curved surface portion outward. The inner surface shape of the cover portion 5 forms a concave surface outward from the edge portion 54.

  As described above, in one cover portion 5, the lower leg shaft 53 is fitted with the lower leg shaft 45 of the fan-shaped member 4 with respect to the upper leg shaft 51 fitted into the inner hole 43 a of the cylindrical portion 43 of the fan-shaped member 4. Since the upper leg shaft 51 and the lower leg shaft 53 constitute the upper leg side shaft mechanism, the upper leg shaft 51 and the lower leg shaft 53 are configured so as to be fitted to the shaft hole 39a having the same central axis 37 as the shaft hole 39b of the lower leg side connecting plate 33. And the lower leg side shaft mechanism are separated by a predetermined distance (see dimension DS in FIG. 5A) in parallel. The dimension DS may be set according to the design convenience of the bending operation of the upper leg side joint part 2 and the lower leg side joint part 3 as described in relation to the cylindrical part 43 of the fan-shaped member 4 and the lower leg shaft 45. . In this case, the dimension DS is preferably set so that the lower leg shafts 53 and 45 are within the range of the semicircular portion 54a. As a result, the lower leg 8 rotates around the range of the semicircular portion 54a, so that the lower leg 8 performs a rotation operation close to an actual human lower leg. Further, when it is desired to set the bending angle of the lower leg 8 with priority, the dimension DS is not limited to the above, and the dimension DS may be set so that the lower leg shafts 54 and 45 are provided beyond the range of the semicircular portion 54a.

As shown in FIGS. 6 to 8, the other cover portion 6 is formed on the other side of the pair of lower leg side connection plates 32 and 33 of the upper leg side joint plate 22 and the lower leg side joint portion 3 (see FIG. 6 and 8 on the right side).
Note that the outer diameter shape of the other cover portion 6 is similar to that of the cover portion 5.
That is, as shown in FIGS. 5D, 5E, and 5F, the outer shape is a semicircular portion 64a having an upper shape with the same outer periphery as the upper leg connecting plate 22, and the semicircular portion 64a. An arc portion 64b having a curved surface having a diameter larger than the curved surface 33a on the front side of the lower leg side connecting plate 33 continuously obliquely downward from the front side (right side in the figure) of the semicircular portion 64a. A so-called ball-shaped edge portion 64 is formed which includes a rear end portion (right side in the drawing) and a rear end portion 64c continuously tapered from the lower end of the arc portion 64b. The edge portion 64 has a predetermined thickness along the outer shape.

The rear end and the rear end 64c of the semicircular portion 64a of the edge portion 64 correspond to the thickness of the lower leg side connecting plate 32 (see the dimension D3 in FIG. 3B), like the one cover portion 5. A step 64d and a step 64e are formed at the boundary between the edge portion 64 and the non-notched portion of the edge portion 64, respectively, in the outer surface direction (left side in FIG. 6B).
Moreover, the circular arc part 64b leaves the inner area | region of the virtual circle (refer the broken line C in FIG.5 (d)) concentric and concentric with the semicircular part 64a, and the thickness (in FIG.3 (b)) of the lower leg side connection board 32 is left. Projecting inward (to the right in FIG. 6B) with the same length (see dimension D1 in FIG. 5E).
Note that the region 67 on the rear end side of the stepped portion 64e of the edge portion 64 is formed so as to protrude inward (to the right in FIG. 5E).

Further, the shape of the outer surface 65 of the cover portion 6 is formed so as to protrude from the edge portion 64 (semi-circular portion 64a, arc portion 64b, and rear end portion 64c) with a smooth convex curved portion outward. At the same time, the inner surface shape of the cover portion 6 forms a concave surface outward from the edge portion 64.
Furthermore, on the inner surface side of the cover part 6, a large-diameter hole 61 that fits into the cylindrical part 43 of the fan-shaped member 4, a pin hole 63 into which the pin 44 of the fan-shaped member 4 fits, and a pin 52 of the cover part 5 A pin hole 62 to be fitted is provided.

Specifically, the large diameter hole 61 is formed as a hole having a diameter slightly larger than the outer diameter R1 of the cylindrical portion 43 of the fan-shaped member 4 at the center of the semicircular portion 64a. Note that the depth of the large-diameter hole 61 is the same as the length of the cylindrical portion 43.
The pin hole 63 is arranged on a vertical line 68 passing through the center of the semicircular portion 64a (see FIG. 5D) and at a position spaced apart by the same dimension as the dimension between the cylindrical part 43 of the fan-shaped member 4 and the pin 44. The diameter of the pin 44 is slightly larger than that of the pin 44 and the same depth as the length of the pin 44.

  The pin hole 62 is an area close to the outer periphery 64 of the semicircular portion 64a, and is rotated backward from the perpendicular 68 passing through the center of the large-diameter hole 61 in a backward direction at a predetermined angle θ1 (right in FIG. 5D). Direction). That is, the pin hole 62 is disposed at a position corresponding to the position of the pin 52 of the cover unit 5. Therefore, in this embodiment, the angle θ1 at which the pin hole 62 is disposed is also set to approximately 55 degrees. The angle θ1 is set to the same angle as the angle range θ1 in which the circumferential groove 25 of the upper leg side connecting plate 22 is formed, and thus the circumferential groove 25 of the upper leg side connecting plate 22 is formed. Along with the design change of the angle range θ1, the design of the angle θ1 at which the pin hole 62 is arranged is also changed. Further, the depth of the pin hole 63 is formed such that the tip of the pin 52 can be fitted.

  As described above, each mechanism of the connecting portion is formed integrally with each member constituting the one connecting portion, the fan-shaped member 4 and the other cover portion 6 formed integrally with the one cover portion 5. Each member constituting the other connecting portion is combined with the upper leg side joint portion 2 and the lower leg side joint portion 3, respectively, and each mechanism further includes an outer surface 55 of the cover portion 5 on one side. And it is coat | covered with the outer surface 65 of the cover part 6 distribute | arranged to the other side.

The case where the joint part 1 is assembled will be described with reference to FIG.
When assembling the joint 1, first, the upper leg side connecting plate 22 of the upper leg side joint 2 is placed between the lower leg side connecting plate 32 and the lower leg side connecting plate 33 of the lower leg side joint 3. The connecting plate 22 is inserted until the outer peripheral surface 22 extends along the upper surface 36 a of the extending portion 36.
Next, one cover portion 5 is combined from one side (left side in the figure) of the upper leg side connecting plate 22 and the lower leg side connecting plate 32. At this time, the pin 52 of the one cover portion 5 is inserted into the circumferential groove 25 of the upper leg side connecting plate 22, and the upper leg shaft 51 of the one cover portion 5 is inserted into the shaft hole 29 of the upper leg side connecting plate 22. And the lower leg shaft 53 of one cover portion 5 is fitted into the shaft hole 39a of the lower leg side connecting plate 32.

Since the length dimension D4 of the upper leg shaft 51 is set slightly longer than the total length of the thickness dimension D3 of the lower leg side connecting plate 33 and the thickness dimension D1 of the upper leg side connecting plate 22, The tip of the shaft 51 slightly protrudes from the upper leg side connecting plate 22.
Further, since the length dimension of the lower leg shaft 53 of one cover portion 5 and the thickness dimension of the lower leg side connecting plate 32 are both set to the dimension D3, the tip of the lower leg shaft 53 is connected to the lower leg side connecting plate 32. Is inserted up to the plate surface on the opposite side, and does not contact the upper leg side connecting plate 22.
Further, the length dimension D5 of the pin 52 is set to a total length dimension of the thickness dimension D3 of the lower leg side connecting plate 33, the thickness dimension D1 of the upper leg side connecting plate 22, and the thickness dimension D3 of the lower leg side connecting plate 33. Therefore, it protrudes from the upper leg side connecting plate 22 by the thickness dimension D3.
Since the rear end and the rear end 54c of the semicircular part 54a of the other cover part 5 are notched with the thickness dimension D3 of the lower leg side connecting plate 33, the notched part extends to the lower leg side connecting plate 33 and the extended leg part. It is in sliding contact with the side surface of the portion 36.

Further, the fan-shaped member 4 is combined from the other side (the right side in the drawing) of the upper leg side connecting plate 22 and the lower leg side connecting plate 33. At this time, the inner hole 43a of the cylindrical portion 43 of the fan-shaped member 4 is fitted to the lower leg shaft 53 of the cover portion 5 that has passed through the shaft hole 29 of the upper leg side connecting plate 22, and the shaft hole 39b of the lower leg side connecting plate 33 is inserted. The lower leg shaft 45 of the fan-shaped member 4 is fitted to the upper part.
Since the length dimension of the lower leg shaft 45 of the fan-shaped member 4 and the thickness dimension of the lower leg side connecting plate 33 are both set to the dimension D3, the tip of the lower leg shaft 45 is opposite to the lower leg side connecting plate 33. The plate is inserted to the opposite side plate surface and does not come into contact with the upper leg side connecting plate 22.
In addition, since the length dimension of the cylindrical portion 43 of the fan-shaped member 4 and the thickness dimension of the lower leg side connecting plate 33 are both set to the dimension D3, the tip of the cylindrical portion 43 is in sliding contact with the upper leg side connecting plate 22. At the same time, the one surface side 41 a of the fan-shaped member 4 is in sliding contact with the side surface of the lower leg side connecting plate 33.

The screw S inserted into the cylindrical portion 42 of the fan-shaped member 4 and the hole 41 c of the cylindrical portion 43 is tightened into the screw hole 51 a of the upper leg shaft 51. As a result, the upper leg side joint portion 2 is pivotally supported (slidably fitted) on the upper leg shaft 51 and the lower leg side joint portion 3 is pivotally supported on the lower leg shafts 35 and 53. In addition, since each member is in sliding contact with no gap, it is held firmly without rattling.
Finally, the other cover part 6 is combined from the other side (right side in the figure). At this time, the large-diameter hole 61 of the other cover portion 6 is fitted to the cylindrical portion 42 of the fan-shaped member 4, and the pin hole 62 of the other cover portion is fitted to the pin 44 of the fan-shaped member 4.
The rear end and the rear end 64c of the semicircular portion 64a of the other cover portion 6 are notched with the thickness dimension D3 of the lower leg side connecting plate 32, so that the notched portion is the lower leg side connecting plate 32 and It is in sliding contact with the side surface of the extended portion 36.
Furthermore, since the arc portion 64b of the other cover portion 6 protrudes with the same length as the thickness dimension D1 of the lower leg side connecting plate 32, the arc portion 64b of the one cover portion 5 abuts exactly.

As shown in FIG. 9, the joint portion 1 assembled in this way is covered by the smooth curved outer surfaces 55 and 56 of the cover portion 5 and the cover portion 6. At this time, the edge portions 54 and 64 of the cover portion 5 and the cover portion 6 are the semicircular portion 54a of the cover portion 5 and the semicircular portion 64a of the cover portion 6 respectively of the outer peripheral surface 22a of the upper leg side connecting plate 22. The arcuate part 54b of the cover part 5 and the arcuate part 64b of the cover part 6 are in contact with each other without any gap, and the rear end part 54c of the cover part 5 and the rear end part 64c of the cover part 6 are The lower leg side support shaft portion 31 is in sliding contact with both side surfaces of the concave curved surface 36c provided on the rear side of the extending portion 36. Thereby, the joint part 1 is collected into one hook-like appearance shape.
Further, when the joint portion 1 is combined with the end portion of the upper leg 7 and the end portion of the lower leg 8, as shown in FIG. 1 (a), FIG. 2 (b), and FIG. Since it has an external appearance integrated with the end of the leg 7 and the end of the lower leg 8, it has a shape closer to a real human joint.

Below, operation | movement of the joint part 1 is demonstrated.
First, operation | movement of the upper leg side joint part 2 is demonstrated, referring FIG. 10 (a) (b). 10 (a) and 10 (b), in order to make the explanation easy to understand, the state where the fan-shaped member 4 and the cover part 6 are removed and the cover part 5 is fixed and the upper leg side joint part is shown. 2 shows the operation.
The upper leg side joint portion 2 is rotatably supported by an upper leg shaft 51 fitted in the shaft hole 29 of the upper leg side connecting plate 22 and rotates around a circle center 26 of the upper leg side connecting plate 22. . A pin 52 is inserted into the circumferential groove 25 of the upper leg side connecting plate 22.

When the upper leg side joint 2 rotates in the forward bending direction (rotation in the right direction in the figure, see the right arrow in FIG. 10A), the pin 52 contacts the other end 25b of the circumferential groove 25. This restricts the rotation of the upper leg side joint 2 in the forward bending direction.
When the upper leg joint portion 2 rotates in the backward bending direction (leftward rotation in the figure, see the leftward arrow in FIG. 10B), the pin 52 contacts the one end 25a of the circumferential groove 25. Thus, the rotation in the backward bending direction of the upper leg side joint 2 is restricted.
In the present embodiment, the circumferential groove 25 is formed in an angle range of approximately 55 degrees from the one end 25a to the other end 25b, so that the upper leg side joint portion 2 is bent backward by the angle, and more than that. The backward bending rotation is regulated. Therefore, the upper leg side joint 2 can freely rotate within the angular range.

Next, the operation of the lower leg side joint 3 will be described with reference to FIGS. In FIGS. 11A and 11B, for easy understanding, the lower leg side joint portion 3 is removed in a state where the cover portion 6 is removed, the fan-shaped member 4 is indicated by a broken line, and the cover portion 5 is fixed. Shows the operation.
The upper leg side joint portion 3 is rotatably supported by fitting the lower leg shaft 53 and the shaft hole 39a of the cover portion 5 and the lower leg shaft 45 of the fan-like member 4 and the shaft hole 39b. The shaft center of the lower leg shaft 53 and the lower leg shaft 45 is rotated about the rotation center 37.

When the lower leg side joint portion 3 rotates in the forward bending direction (rotation in the right direction in the figure, see the right-pointing arrow in FIG. 11A), the cylindrical portion 43 of the fan-like member 4 is connected to the lower leg side connecting plate 33. By making contact with the concave curved portion 33c, the rotation of the lower leg side joint portion 3 in the forward bending direction is restricted.
When the lower leg joint 3 rotates in the backward bending direction (left rotation in the figure, see the left arrow in FIG. 11B), the rotation is not particularly limited, and the upper leg joint 2 is The upper leg 7 attached and the lower leg 8 attached with the lower leg joint part 3 can freely rotate until they come into contact with each other.

  Next, a specific operation in a state where the upper leg side joint part 2 and the lower leg side joint part 3 are assembled will be described with reference to FIGS. 12 to 14, the cover portion 6 is removed, the fan-shaped member 4 is indicated by a broken line, and the upper leg 7 and the lower leg 8 are indicated by alternate long and short dash lines for easy understanding. Further, the operation of the upper leg side joint part 2 and the lower leg side joint part 3 with the cover part 5 fixed is shown.

  When the upper leg 7 and the lower leg 8 are bent forward (elongated), that is, when the joint portion 1 is bent forward at the maximum, as shown in FIG. The other end 25b and the pin 52 come into contact with each other to restrict the rotation of the upper leg side joint portion 2 in the forward bending direction, and the concave bent portion 33c of the lower leg side connecting plate 33 and the cylindrical portion 43 of the fan-like member 4 come into contact with each other. The rotation of the lower leg joint 3 in the forward bending direction is restricted. Thereby, the forward bending of the upper leg 7 and the lower leg 8 is regulated. At this time, the lower end 72 on the front side of the upper leg 7 and the upper end 82 on the front side of the lower leg 8 are close to each other, so that the joint portion 1 is hidden by the upper leg 7 and the lower leg 8.

  Next, as shown in FIG. 13, in the state where only the upper leg 7 is bent backward (see the left-pointing arrow in the drawing), the upper leg side connecting plate 22 rotates about the circle center 26 of the upper leg side connecting plate 22. As a backbend. In the state where it is bent back to the maximum, the one end 25a of the circumferential groove 25 of the upper leg side connecting plate 22 and the pin 52 come into contact with each other to restrict the rotation of the upper leg side joint portion 2 in the backward bending direction, and the lower leg side connecting plate. The concave curved portion 33c of 33 and the cylindrical portion 43 of the fan-shaped member 4 are in contact with each other, and the rotation of the lower leg side joint portion 3 in the forward bending direction is restricted. At this time, the lower end 72 on the front side of the upper leg 7 and the upper end 82 on the front side of the lower leg 8 are separated by the amount of backward bending of the upper leg 7, but the joint portion 1 is covered with the cover portion 5 and the cover portion 6. Therefore, each mechanism of the joint part 1 is not exposed and the aesthetic appearance is maintained.

  Next, as shown in FIG. 14, in addition to the state where the upper leg 7 is bent backward, the lower leg 8 is also bent backward (see the left arrow in the figure), the lower leg side connecting plate 22 is connected to the lower leg. The shaft 53 and the lower leg shaft 45 are rotated backward about the axis 37 as the rotation center 37. At this time, since the arc portion 54b of the cover portion 5 and the arc portion 64b of the cover portion 6 are formed coaxially with the lower leg shaft 53 and the lower leg shaft 45, the arc portion 54b and the arc portion during the backward bending rotation of the lower leg 8 are formed. In the exposed portion 64b, the distance between the lower leg shaft 53 and the lower leg shaft 45 does not change. Therefore, the arc part 54b of the cover part 5, the arc part 64b of the cover part 6, and the outer surface 55 extending from the arc part 54b and the outer surface 65 extending from the arc part 64b are always integrated with the upper end 82 of the lower leg 8. It has become.

  Further, in the state where the rear leg is bent to the maximum, the rear side 73 of the upper leg 7 to which the upper leg side joint part 2 is attached and the rear side 83 of the lower leg 8 to which the lower leg side joint part 3 is attached come into contact with each other. No more backward bending. At this time, the lower end 72 on the front side of the upper leg 7 and the upper end 82 on the front side of the lower leg 8 are largely separated from each other. However, as shown in FIG. 15, the joint portion 1 has the outer surface 55 and the cover portion 6 of the cover portion 5. Since the outer surface 65 is covered, each mechanism of the joint portion 1 is not exposed. Further, the shape of the rear side of the joint portion 1 (the concave curved surface 36c of the extending portion 36) is formed as a curved surface that is an extension of the bulge of the calf of the lower leg 8, so that it looks integral with the lower leg 8. Thereby, the joint part 1 becomes integral with the upper leg 7 and the lower leg 8 from the extended state to the bent state, and can maintain the aesthetic appearance of the doll.

Further, the center line 38a of the upper leg side connecting plate 22 of the upper leg side joint part 2 and the center line 28b of the extending part 36 of the lower leg joint part 3 are combined with a deviation of D2 (FIG. 3B). )reference).
An overall view seen from the back side of the leg is shown in FIG. When the joint part 1 is combined with the upper leg 7 and the lower leg 8, the upper leg 7 and the lower leg 8 are connected to the center line 38a of the upper leg side connecting plate 22 and the center line 28b of the extension part 26 of the lower leg joint part 3, respectively. Therefore, they are combined with a deviation dimension D2. Thereby, it can be set as the leg part of the more realistic doll which reproduced the shape of a real human leg part which has the lower leg outside the upper leg.

  In the present embodiment, the other end side angle restricting mechanism is configured by the cylindrical portion 43 coming into contact with the concave curved portion 33c. In addition, the base end portion of the upper leg shaft 51 is used as the lower leg portion. It is formed in a cylindrical shape having a slightly smaller diameter than the concave curved portion 32c on the upper end side of the side connecting plate 32, and the base end portion of the upper leg shaft 51 is configured to contact the concave curved portion 32c of the lower leg side connecting plate 32, It is good also as an other end side angle control mechanism which controls the rotation angle of the lower leg side connection board 32 by both the concave curved part 32c and the concave curved part 33c.

In addition, the above-described fitting relationship with each shaft and shaft hole, and the relationship between the pin 52 and the circumferential groove 25 are not limited thereto, and the above-described one end side shaft mechanism and one end side angle regulating mechanism, Furthermore, as long as the other end side shaft mechanism and the other end side angle restricting mechanism are configured, the shaft, the shaft hole, the pin 52, and the circumferential groove 25 may be provided in any member to be combined.
For example, the upper leg shaft 51 may be provided on the fan-shaped member 4, the cylindrical portion 43 may be provided on one cover portion 5, and the lower leg shafts 53 and 45 may be provided on the lower leg side connecting plates 32 and 33, respectively.

Furthermore, in the present embodiment, the one cover portion 5 and the one connecting portion are integrally formed, but the present invention is not limited to this, and the one cover portion 5 and the one connecting portion may be formed separately. Alternatively, it is also within the scope of the present invention to integrally form the other cover portion 6 and the other connecting portion (fan-like member 4).
In this embodiment, one upper leg side connecting plate 22 is provided and a pair of lower leg side connecting plates 32 and 33 are provided. However, the present invention is not limited to this, and a plurality of upper leg side connecting plates 22 are provided. It may be provided, or one or three or more lower leg side connecting plates may be provided. Even in that case, it is within the scope of the present invention as long as each mechanism is provided.

In the first embodiment, the case where the joint portion 1 is applied to the leg portion of the doll has been described as an example. However, the present invention is not limited thereto, and the joint portion 1 is applied to other portions of the doll, for example, the arm portion. Is also possible.
Below, an example which applied the joint part 1 to the arm part of a doll is demonstrated.
In addition, the joint part 1 of a present Example is integrated in the elbow part of the arm part whose internal space is narrower than the knee part of a leg part.
Therefore, although the structure which simplified the joint part 1 of Example 1 mentioned above is employ | adopted, one end side joint part is equipped with a disk-shaped one end side connection board, and the other end side joint part pinches | interposes this disk. One end side shaft mechanism that includes two other end side connection plates and rotatably supports the one end side joint portion, and the other end side shaft mechanism that rotatably supports the other end side joint portion is one end side shaft mechanism And an end-side angle restricting mechanism and an angle-side restricting mechanism on the other end side, covering the respective mechanisms and integrated with the end portion of the first member and the end portion of the second member. The basic configuration including a pair of curved surface portions forming the same is the same.
Therefore, in this embodiment, the same reference numerals are used for the structural members having substantially the same shape as in the first embodiment, and the description is omitted, and the simplified configuration is different from the above embodiment. The explanation will be focused on the parts.
