FIG. 1 is a perspective view of a toy according to one embodiment of the present invention.
In FIG. 1, a toy 1 has a structure imitating a humanoid robot, having left and right arm parts 5, left and right leg parts 8, a torso part 2 of the toy main body, and a head part 6. For example, the head 6 including the neck portion moves back and forth and left and right. Also, regarding the arm portion 5, the shoulder portion can freely rotate, the upper arm portion 10 and the forearm portion 20 are rotatably and bendably connected by the elbow portion, and the hand portion 30 is also rotatably connected. has been done. Further, the leg portion 8 is configured such that the thigh portion 40 and the lower leg portion 50 can be bent and rotated by the joint structure of the knee portion. Further, the foot portion 60 is also configured to be able to bend and rotate at the ankle.

Hereinafter, the structure of the thigh section 40 configured as a first member attached to the body section 2 so as to be able to change its direction will be described. Note that the left and right legs 8 are attached to the body 2 on the left and right, and have the same configuration with bilateral symmetry, so here, in FIG. The section 40 will be explained.

FIG. 2 is a front view of the leg portion 8 of the toy 1 shown in FIG. 1, viewed from the front.
As shown in FIG. 2, the leg portion 8 has a portion corresponding to the hip joint at the upper end of the thigh portion 40, which is approximately the same as the upper end portion of the skeleton portion 40a (see FIG. 3) extending along the axis CL1. A spherical upper connecting portion 42j is connected to the body portion 2. The upper connecting portion 42j is rotatably supported via, for example, a shaft pin 81 (see FIG. 6) that passes through the tips of the left and right shaft members 3 extending from the center side of the body portion 2 to the left and right sides in the front and back direction. has been done. Therefore, in FIG. 2, the thigh 40 is supported so as to be rotatable about an axis CL2 in the front-rear direction extending in a direction perpendicular to the paper surface. Further, the left and right shaft members 3 supporting the upper connecting portion 42j are attached to the body portion 2 so as to be rotatable about the left and right axis CL3. Therefore, the thigh 40 is supported so as to be rotatable in the front-rear direction about the left and right axis CL3.

FIG. 3 is an exploded perspective view of the thigh 40 shown in FIG. 2 with the outer shell 43 removed. FIG. 4 is a cross-sectional view of a portion taken along line XX shown in FIG.

As shown in FIGS. 3 and 4, the thigh section 40 includes a skeleton section 40a connected to the body section 2 via the left and right shaft members 3, and an outer section that is divided into two parts, for example, in proportion to surround the skeleton section 40a. An outer shell portion 43 (43a, 43b) constituting a shell is provided. The skeleton portion 40a extends along the axis CL1, and its upper side is connected to the left and right shaft members 3 as described above, and its lower side is connected to the upper end portion 51b of the lower leg portion 50. The connection part between the lower leg part 50 and the thigh part 40 is such that the upper end part 51b of the lower leg part 50 and the knee side connection part 41b of the skeleton part 40a of the thigh part 40 are penetrated by the knee support shaft 48 and bent. It constitutes a possible knee joint.

In the skeleton part 40a, a first axis 41 on the knee joint side (the lower part in the figure) and a second axis 42 on the hip joint side (the upper part in the figure) are connected along the direction of the axis CL1. . Further, the outer shell portion 43 is rotatably provided with respect to the skeleton portion 40a around the axis CL1 of the skeleton portion 40a. The rotatable structure of the outer shell portion 43 is based on a sliding structure between the inner peripheral surface 43is of the outer shell portion 43 and the outer surface of the skeleton portion 40a. For example, a pair of annular guide walls 43c arranged in the direction of the axis CL1 are provided on the inner circumferential surface 43is of the outer shell 43, and between the pair of guide walls 43c, a diameter The guide portion 41d protruding in the direction is fitted into the guide portion 41d. Therefore, the outer shell portion 43 can rotate in the direction around the axis CL1 with respect to the skeleton portion 40a without being restricted in any way.

Further, the outer shell portion 43 has a configuration in which a peripheral edge portion 43e on the upper end side (body portion 2 side) changes in position in the direction of the axis CL1. That is, the peripheral portion 43e is configured to have a portion that is close to the body portion 2 and a portion that is remote from the body portion 2.

FIG. 5 is an exploded perspective view showing a state in which the skeleton of the portion corresponding to the thigh shown in FIG. 2 is divided into two parts.
As shown in FIG. 5, the first axis 41 and the second axis 42 of the skeleton part 40a can be separated in the direction of the axis CL1, and in the connected state, the first axis 41 and the second axis 42 have a length along the direction of the axis CL1. is configured to be expandable. In this expandable structure, for example, the first shaft 41 is provided with a slide holding hole 41h that is elongated along the direction of the axis CL1 and has a substantially rectangular cross section, and the second shaft 42 is provided with a slide holding hole 41h. A fitting insertion portion 42a having a substantially rectangular cross-sectional shape is provided which can be fitted and inserted into the hole 41h. Therefore, when the first shaft 41 and the second shaft 42 are assembled, the length of the skeleton portion 40a changes as the fitting insertion portion 42a slides within the slide holding hole 41h.

Further, a disc-shaped flange 42f is provided on the base end side (upper side in the figure) of the fitting insertion portion 42a of the second shaft 42. On the other hand, on the inner circumferential surface 43is of the outer shell portion 43, an edge guide is provided with a surface parallel to the pair of guide walls 43c at a position aligned with the guide wall 43c in the direction of the axis CL1 (upper position in the figure). A wall 43f is provided. When the thigh 40 is assembled (the state shown in FIG. 4), the flange 42f is located between the edge guide wall 43f and the guide wall 43c (the upper one of the pair of guide walls 43c). It is located in This restricts the movement of the collar portion 42f in the direction of the axis CL1, and maintains the connected state so that the first shaft 41 and the second shaft 42 do not come off.

In the second shaft 42, a root portion 42b between the upper connecting portion 42j and the collar portion 42f is configured in a semi-cylindrical shape (see FIG. 5) extending in the direction of the axis CL1. That is, the outer circumferential surface of the root portion 42b is configured such that one side thereof is not a circumferential surface but a flat portion 42k that is a flat surface.

FIG. 6 is an exploded perspective view of the skeleton portion 40a that is finely disassembled into component parts.
A pressing member 42m that contacts the inner surface of the slide holding hole 41h with a predetermined biasing force is provided on the outer surface in the radial direction of the fitting insertion portion 42a of the second shaft 42 (see FIG. 5). . As shown in FIG. 6, a pressing force applied by an elastic member 42n toward the outer surface in the radial direction of the second shaft 42 is applied to a horizontal hole 42h opened in a direction perpendicular to the sliding direction of the second shaft 42. 42 m of members are installed inside. Therefore, when the fitting insertion portion 42a is inserted into the slide holding hole 41h, the pressing member 42m can come into contact with the inner surface of the slide holding hole 41h.

Note that the first shaft 41 is connected to a holding hole forming portion 41a that forms the slide holding hole 41h and a knee side connecting portion 41b that is connected to the upper end portion 51b on the lower leg portion 50 side and forming a knee joint portion. The configuration is as follows. Further, the holding hole forming part 41a has a structure that is divided into two parts, and is designed to hold in its mouth a connecting protrusion 41c protruding from the upper end side of the knee side connecting part 41b. Rotatably coupled. Further, in the holding hole forming portion 41a, the two proportionally divided portions are fastened by screws 82 or the like, and the portion where the screws 82 are provided is configured as the above-mentioned protruding guide portion 41d.

7 is a cross-sectional view of a portion taken along line YY in FIG. 2, showing a state in which the skeleton portion 40a is short, and FIG. 8 is a cross-sectional view of a portion taken along line YY of FIG. It is a sectional view showing a state where the skeleton part 40a is long in the figure.

When the skeleton portion 40a is at its shortest length, as shown in FIG. 7, the fitting insertion portion 42a is inserted most deeply into the slide holding hole 41h. In this case, a locking protrusion 42p protruding from the tip end surface of the pressing member 42m fits into the first locking recess 41p. Thereby, the short state of the skeleton portion 40a is maintained. Further, in the short state of the skeleton portion 40a, the peripheral edge portion 43e of the outer shell portion 43 is located close to the upper connecting portion 42j.

On the other hand, when the skeleton portion 40a is at its longest length, as shown in FIG. 8, the fitting insertion portion 42a is inserted at its shallowest depth into the slide holding hole 41h. In this case, the locking protrusion 42p of the pressing member 42m fits into the second locking recess 41q provided on the opening side of the slide holding hole 41h. Thereby, the long state of the skeleton portion 40a is maintained.

FIG. 9 is a side view showing a state in which the outer shell part 43 is in an initial state (reference state) and the skeleton part 40a is short and the thigh part 40 is raised forward.
When performing a bending operation to raise the thigh 40 forward, as shown in FIG. In this case, the peripheral edge portion 43e and the lower edge portion 2e of the body portion 2 come into contact with each other at a relatively early stage after the first bending, and the bending angle does not become very large.

FIG. 10 is an enlarged front view of the thigh 40 showing a state in which the outer shell 43 is rotated from the initial state (reference state). FIG. 11 is a side view showing a state in which the thigh 40 is raised forward after the outer shell 43 is rotated.
Before bending the leg portion 8, as shown in FIG. 10, for example, the outer shell portion 43 is rotated approximately 90 degrees. When the outer shell portion 43 is rotated in this manner, the peripheral edge portion 43e on the side (inside) that bends the thigh portion 40 becomes distant from the lower end edge portion 2e. That is, the peripheral edge portion 43e, which is configured to change its position in the direction of the axis CL1, is in a state where the portion retreated toward the knee with respect to the lower edge portion 2e is the inner side of the bend. In this state, as shown in FIG. 11, the peripheral portion 43e is bent (rotated about the axis CL3) until it comes into contact with the lower end edge 2e of the body portion 2. In this case, the bending angle is larger than the bending angle during the bending operation before rotating the outer shell portion 43 (the state shown in FIG. 9).
Although the rotation angle of the outer shell portion 43 is described as approximately 90 degrees, it is not limited to this in any way, and the position where the outer shell portion 43 can be bent the most (the position where the thigh portion 40 can be bent the most) is as follows. It depends on the shape of the adjacent lower end edge 2e.

FIG. 12 is a front view showing the skeleton part 40a in an extended state.
As shown in FIG. 10, when the skeleton portion 40a is lengthened, the distance between the peripheral edge portion 43e and the lower edge portion 2e becomes larger. Further, the outer shell portion 43 is rotated 90 degrees to the right as shown in the figure, to further increase the distance between the peripheral edge portion 43e and the lower edge portion 2e on the inside (front side) in the bending direction.

FIG. 13 is a side view showing a state in which the thigh part 40 is raised forward with the skeleton part 40a extended.
When a bending operation is performed while stretching the skeleton 40a and rotating the outer shell 43 as described above, the bending angle of the thigh 40 becomes very large, as shown in FIG. Bend. Further, in this case, the flat portion 42k of the root portion 42b of the skeleton portion 40a is largely exposed. Thereby, the bending (rotation) can be performed until the root portion 42b touches the lower end edge 2e. Further, as shown in FIG. 11, in a state where the thigh 40 is largely bent forward, the thigh 40 is further moved in the lateral direction (right direction). This further increases the bending angle.

As described above, in one aspect of the present invention, the outer shell portion 43 is configured to be able to rotate in the outer circumferential direction relative to the skeleton portion 40a, thereby preventing interference with members adjacent to the outer shell portion 43. It becomes possible to change the position, and for example, it becomes possible to widen the permissible range of the connection direction (bending angle, etc.) between the body part 2 and the leg part 8.

In this aspect, since the peripheral edge 43e of the outer shell 43 is configured to change in the direction of the axis CL1, the position where the outer shell 43 interferes with a member adjacent to it can be changed.

In this aspect, the distance between the outer shell part 43 and the body part 2 can be changed because the length of the skeleton part 40a can be expanded and contracted with respect to the length of the outer shell part 43 in the direction of the axis CL1. It becomes possible to avoid interference between the peripheral edge portion 43e of the shell portion and the body portion 2.

In the skeleton part 40a of this embodiment, since the second shaft 42 can slide while being guided by the slide holding hole 41h of the first shaft 41, the length of the skeleton part 40a can be changed.

In this aspect, the second shaft 42 can slide while being in contact with the inner surface of the slide holding hole 41h by the pressing member 42m, so that rattling between the second shaft 42 and the slide holding hole 41h can be prevented. It can be eliminated. This allows the first shaft 41 and the second shaft 42 to expand and contract smoothly without wobbling.

In this aspect, since the pair of circumferential guide walls 43c provided on the inner circumferential surface 43is of the outer shell part 43 are rotatably guided by the protruding guide part 41d of the skeleton part 40a, the outer shell part 43 The portion 43 can be rotated smoothly. Furthermore, since the guide portion 41d is fitted between the pair of guide walls 43c, the axial position of the outer shell portion 43 and the skeleton portion 40a can be regulated (positioned).

In this embodiment, the first shaft 41 and the second shaft 42 are connected to each other by engagement between the edge guide wall 43f provided on the outer shell 43 and the flange 42f of the second shaft 42. , 42 can be regulated to a position where they do not come apart, so a special structure for maintaining the connection between the two shafts 41, 42 is not required between the two shafts 41, 42, and the connection structure can be simplified.

In this aspect, the outer surface of the base portion 42b of the connecting portion with the body portion 2 of the skeleton portion 40a has a flat portion 42k, so that interference with adjacent members can be suppressed by the flat portion 42k. This allows the range of movement of the connecting parts to be widened.

In this aspect, when the slide holding hole 41h and the fitting insertion portion 42a are fitted, the locking protrusion 42p provided on the distal end surface of the pressing member 42m is connected to the first locking protrusion 42p provided on the inner surface of the slide holding hole 41h. Since it is fitted and locked in the recess 41p and the second locking recess 41q, for example, the shortest connected state and the longest connected state of the skeleton part 40a can be maintained.

Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in this embodiment, the movable structure of the thigh 40 has been described, but the movable structure of the toy according to the present invention is not limited to this, and a similar movable structure may be adopted for the upper arm, for example. .
