[0015] 1 and 2 show the configuration of the upper body of a doll body for explaining an embodiment of the present invention.

[0016] The doll body 1 shown in Fig. 1 comprises a torso 2, a pair of left and right arms 3, a first joint member 6, a second joint member 7, and a third joint member 8 that constitute shoulder joints, and a covering member 9. The first joint member 6, the second joint member 7, the third joint member 8, and the covering member 9 are provided for each pair of left and right arms 3.

[0017] The torso 2 includes a frame member 11 disposed on the trunk axis A of the torso 2, a front chest member 12, and a rear chest member 13. The front chest member 12 and the rear chest member 13 are assembled together, and the frame member 11 is housed inside the torso 2, which is surrounded by the front chest member 12 and the rear chest member 13. The rear chest member 13 is fixed to the frame member 11 with screws or the like, and the front chest member 12 assembled to the rear chest member 13 is also fixed to the frame member 11.

[0018] The arm 3 includes a shoulder member 14 that serves as the base of the upper arm. Members (not shown) that form the parts beyond the shoulder, such as the upper arm and forearm, are attached to the shoulder member 14.

[0019] The first joint member 6 and the second joint member 7 are housed inside the body 2. The first joint member 6 is connected to a frame member 11 inside the body 2, and the second joint member 7 is connected to the first joint member 6.

[0020] The third joint member 8 is connected to the shoulder member 14 of the arm 3. An opening 15 is formed at the shoulder of the torso 2, and the third joint member 8 is connected to the second joint member 7 through the opening 15.

[0021] The covering member 9 is formed in an annular shape and is inserted so as to be able to protrude and retract into an opening 15 at the shoulder of the body 2. The third joint member 8, which is connected to the second joint member 7 and the shoulder member 14, respectively, is inserted into the covering member 9 through the opening 15, and the covering member 9 covers the connecting portion between the third joint member 8 and the shoulder member 14.

[0022] 3 and 4 show the shoulder joint structure of the doll body 1, and FIGS. 5 and 6 show the operation of the shoulder joint structure of the doll body 1.

[0023] The connecting portion 20 between the frame member 11 and the first joint member 6 is located below the axial direction of the trunk axis A with respect to an opening 15 (see Figure 1) at the shoulder of the torso 2 and on the front side of the chest in the chest thickness direction anterior to the opening 15, the connecting portion 22 between the second joint member 7 and the third joint member 8 is located at the shoulder of the torso 2 facing the opening 15, and the connecting portion 21 between the first joint member 6 and the second joint member 7 is located between the connecting portion 20 and the connecting portion 22.

[0024] The connecting portion 20 between the frame member 11 and the first joint member 6 is configured as a so-called ball joint consisting of a socket 30 provided in the frame member 11 and a ball 31 provided at one end of the first joint member 6, and the first joint member 6 can rotate relative to the frame member 11 in a rolling motion. Note that the ball may be provided on the frame member 11 side, and the socket may be provided on the first joint member 6 side.

[0025] The connecting portion 21 between the first joint member 6 and the second joint member 7 is composed of a shaft portion 32 provided at the other end of the first joint member 6 and a bearing portion 33 provided at one end of the second joint member 7, and the second joint member 7 is rotatable relative to the first joint member 6 around the shaft portion 32 as a rotation axis. Note that the bearing portion may be provided on the first joint member 6 side, and the shaft portion may be provided on the second joint member 7 side.

[0026] The connecting portion 22 between the second joint member 7 and the third joint member 8 is configured as a so-called ball joint consisting of a socket 34 provided at the other end of the second joint member 7 and a ball 35 provided at one end of the third joint member 8, and the third joint member 8 is rotatable relative to the second joint member 7 in a rolling motion. Note that the ball may be provided on the second joint member 7 side, and the socket may be provided on the third joint member 8 side.

[0027] The connecting portion 23 between the third joint member 8 and the shoulder member 14 of the arm 3 is composed of a bearing portion 36 provided at the other end of the third joint member 8 and a shaft portion 37 provided on the shoulder member 14, and the shoulder member 14 is rotatable with respect to the third joint member 8 around the shaft portion 37 as a rotation axis. Note that the shaft portion may be provided on the third joint member 8 side, and the bearing portion may be provided on the shoulder member 14 side.

[0028] The arm 3 swings back and forth and up and down relative to the body 2 by the rotation of the shoulder member 14 relative to the third joint member 8 and the rotation of the third joint member 8 relative to the second joint member 7 .

[0029] 5 and 6, the first joint member 6 can rotate relative to the frame member 11, with a connecting portion 20 with the frame member 11 configured as a ball joint as a fulcrum, so that a connecting portion 21 with the second joint member 7 moves away from the trunk axis A of the torso 2 in the shoulder width direction. By rotating the first joint member 6 in this manner, the third joint member 8 moves away from the trunk axis A in the shoulder width direction.

[0030] The second joint member 7 is also rotatable relative to the first joint member 6, with the connecting portion 21 with the first joint member 6 as a fulcrum, so that the connecting portion 22 with the third joint member 8 moves away from the trunk axis A of the torso 2 in the shoulder width direction. By such rotation of the second joint member 7, the third joint member 8 is moved further away from the trunk axis A in the shoulder width direction.

[0031] By moving the third joint member 8 away from the trunk axis A in the shoulder width direction, the connection portion 23 between the third joint member 8 and the shoulder member 14 of the arm 3 moves away from the opening 15 at the shoulder of the torso 2. This makes it less likely that the upper arm portion of the arm 3 extending beyond the shoulder member 14 will interfere with the torso 2 or the edge of the opening 15, thereby expanding the range of motion of the arm 3. For example, when moving the arm 3 forward of the chest of the torso 2, it becomes possible to move the arm 3 so that the arm 3 overlaps the chest of the torso 2.

[0032] Furthermore, the first joint member 6 is rotatable relative to the frame member 11, with a connection portion 20 with the frame member 11 configured as a ball joint as a fulcrum, so as to move the third joint member 8 forward in the chest thickness direction. This rotation of the first joint member 6 positions a connection portion 23 between the third joint member 8 and the shoulder member 14 of the arm 3, i.e., a portion that serves as a fulcrum for the swing of the arm 3, close to the edge of the front chest side of the opening 15 at the shoulder of the torso 2. This makes it less likely that the upper arm portion of the arm 3 extending beyond the shoulder member 14 will interfere with the torso 2 or the edge of the front chest side of the opening 15, further expanding the range of motion of the arm 3. In other words, the range of motion when moving the arm 3 forward of the torso 2 is expanded.

[0033] By arranging the connecting part 20, which serves as the fulcrum for the rotation of the above-described first joint member 6, on the front side of the chest, which is forward in the chest thickness direction with respect to the opening 15, the arm 3 can be moved further forward of the torso 2 than when it is located on the rear side of the chest in the chest thickness direction. Furthermore, because the connecting part 20, which serves as the fulcrum for the rotation of the first joint member 6, is located on the chest, further axially lower than the opening 15 at the shoulder of the torso 2, the rotation radius of the third joint member 8 can be increased. The first joint member 6 rotates within a limited space inside the torso 2, and the rotation angle of the first joint member 6 is naturally limited. However, by increasing the rotation radius of the third joint member 8, the displacement amount of the third joint member 8 can be increased for a given rotation angle of the first joint member 6.

[0034] Furthermore, if the connecting part 20, which serves as the rotation fulcrum of the first joint member 6, is provided axially above the trunk axis A with respect to the opening 15 at the shoulder of the torso 2, the upper part of the torso 2 (the position near the collarbone in the human body) will become thicker in the chest thickness direction in order to secure space for the connecting part 20, which will spoil the appearance. Therefore, by locating the connecting part 20, which serves as the rotation fulcrum of the first joint member 6, in the chest part of the torso 2, it is possible to secure space inside the chest by utilizing the bulge of the chest breast, without creating an unnatural bulge in the appearance of the torso 2.

[0035] As the third joint member 8 moves, the covering member 9 is dragged by the third joint member 8 and protrudes from the opening 15 at the shoulder of the torso 2, or comes into contact with the third joint member 8 and retracts into the opening 15, so that the connecting portion 23 between the third joint member 8 and the shoulder member 14 is kept covered by the covering member 9. This makes it possible to expand the range of motion of the arm 3 of the doll body 1 while maintaining a natural appearance.

[0036] Furthermore, in the above embodiments of the present invention, the first joint member 6 and the frame member 11, and the second joint member 7 and the third joint member 8 are connected by ball joints, and the first joint member 6 and the second joint member 7, and the third joint member 8 and the shoulder member 14 are connected by shafts and bearings. However, the structures of the connecting parts of the shoulder joint structure of the present invention are not limited to those described above. [Explanation of symbols]
