[0055] Hereinafter, one aspect of the present invention will be described with reference to the accompanying drawings. Furthermore, in the following description, the terms "up / down," "front / back," and "left / right" will be used interchangeably with "right / left / right." Figure 1 The orientation of the toy shown is used as a reference for recording.

[0056] Figure 1 This is a perspective view of one embodiment of the toy of the present invention.

[0057] exist Figure 1 In this design, toy 1 is a humanoid robot with left and right arms 5, left and right legs 8, a torso 2, and a head 6. For example, the head 6 includes a neck and can move forward, backward, left, and right. Furthermore, the shoulders of the arms 5 can rotate freely; the upper arms 10 and forearms 20 are connected by elbows that can rotate and bend; and the hands 30 are also rotatably connected. The legs 8 are configured such that the thighs 40 and lower legs 50 can bend and rotate via knee joints. The feet 60 are configured to bend and rotate at the ankle joints.

[0058] The structure of the thigh section 40 will now be described. The thigh section 40 is configured as a first member that can be mounted with its orientation changed relative to the torso section 2. Furthermore, the left and right leg sections 8 are mounted symmetrically and identically to the torso section 2. Here, we will describe... Figure 1 The description will focus on the right side (left leg 8 of the robot) of the thigh 40 when the robot is facing the paper.

[0059] Figure 2 View from the front Figure 1 The front view is obtained by showing the leg 8 of toy 1.

[0060] like Figure 2 As shown, at the upper end of the thigh portion 40 of the leg portion 8, corresponding to the hip joint, the skeletal portion 40a extends along the axis CL1 (see reference). Figure 3 The upper part of the ) is connected to the body part 2 by a roughly spherical upper connecting portion 42j. The upper connecting portion 42j is connected to the body part 2, for example, by means of a pivot pin 81 (see reference). Figure 6 Supported for rotation, the pivot pin 81 passes through the front end of the left and right pivot members 3 extending from the center side of the body portion 2 to the left and right sides in the front-rear direction. Therefore, in Figure 2 In this configuration, the thigh portion 40 is supported so that it can rotate about axis CL2 in a forward-backward direction extending perpendicular to the paper. Furthermore, the left and right axis members 3 supporting the upper connecting portion 42j are rotatably mounted on the torso portion 2 about the left and right axis CL3. Therefore, the thigh portion 40 is supported so that it can rotate forward and backward about the left and right axis CL3.

[0061] Figure 3 It is removed Figure 2 An exploded perspective view of the outer shell portion 43 of the thigh portion 40 shown. Figure 4 It is along Figure 1 A sectional view of the portion shown by line XX.

[0062] like Figure 3 and Figure 4 As shown, the thigh portion 40 includes: a skeleton portion 40a, which is connected to the torso portion 2 via left and right axis members 3; and an outer shell portion 43 (43a, 43b), which is proportionally distributed as, for example, two members surrounding the skeleton portion 40a to form an outer shell. The skeleton portion 40a extends along the axis CL1, with its upper side connected to the left and right axis members 3 as described above, and its lower side connected to the upper end portion 51b of the lower leg portion 50. A knee joint capable of bending is formed by a knee support shaft 48 passing through the upper end portion 51b of the lower leg portion 50 and the knee-side connection portion 41b of the skeleton portion 40a of the thigh portion 40.

[0063] For the skeleton portion 40a, the first axis 41 (lower part in the figure) on the knee joint side and the second axis 42 (upper part in the figure) on the hip joint side are connected along the direction of axis CL1. Furthermore, the outer shell portion 43 is configured to rotate relative to the skeleton portion 40a about the axis CL1 of the skeleton portion 40a. This rotatable structure of the outer shell portion 43 is formed by a sliding structure between the inner circumferential surface 43is of the cylindrical outer shell portion 43 and the outer surface of the skeleton portion 40a. For example, it is structured such that a pair of annular guide walls 43c arranged in the direction of axis CL1 are provided on the inner circumferential surface 43is of the outer shell portion 43, and a guide portion 41d protruding radially from the outer surface of the skeleton portion 40a is embedded between these pair of guide walls 43c. Therefore, the outer shell portion 43 can rotate relative to the skeleton portion 40a in the direction about axis CL1 without any restriction.

[0064] Furthermore, the outer shell portion 43 is configured such that the peripheral portion 43e on its upper end side (the side closest to the body portion 2) varies 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 separate from it.

[0065] Figure 5 It means to Figure 2 The diagram shown is an exploded perspective view of the skeleton, which corresponds to the thigh area, divided into two parts.

[0066] like Figure 5 As shown, the first shaft 41 and the second shaft 42 of the skeleton part 40a can be separated in the direction of the axis CL1, and in the connected state, the length can be extended or retracted along the direction of the axis CL1. For this telescopic structure, for example, the first shaft 41 is provided with a sliding retaining hole 41h that is longer in the direction of the axis CL1 and has a generally rectangular cross-sectional shape, and the second shaft 42 is provided with a fitting insertion part 42a that can be fitted and inserted into the sliding retaining hole 41h and has a generally rectangular cross-sectional shape. Therefore, when the first shaft 41 and the second shaft 42 are assembled, the length of the skeleton part 40a is changed by sliding the fitting insertion part 42a within the sliding retaining hole 41h.

[0067] Furthermore, 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 peripheral surface 43is of the outer casing portion 43, a flange guide wall 43f is provided at a position parallel to a pair of guide walls 43c in the direction of the axis CL1 (upper side in the figure), and this flange guide wall 43f has a surface parallel to the guide wall 43c. Furthermore, in the state where the thigh portion 40 is assembled ( Figure 4In the state shown, the flange portion 42f is located between the flange guide wall 43f and the guide wall 43c (the upper guide wall of a pair of guide walls 43c). Thus, movement of the flange portion 42f in the direction of the axis CL1 is restricted, and the connection is maintained in a manner that prevents the first axis 41 and the second axis 42 from disengaging.

[0068] In the second axis 42, the connecting base 42b between the upper connecting portion 42j and the flange portion 42f is configured as a semi-cylindrical shape extending along the axis CL1 (see reference). Figure 5 That is, the outer peripheral surface of the connecting base 42b is a flat portion 42k, which is a flat surface on one side, not a circular surface.

[0069] Figure 6 It is an exploded three-dimensional diagram obtained by subdividing the skeleton part 40a according to its constituent elements.

[0070] The outer surface of the fitting insertion portion 42a of the second shaft 42 in the radial direction (refer to) Figure 5 A pressing member 42m is provided that contacts the inner surface of the sliding retaining hole 41h with a specified applied force. For example... Figure 6 As shown, a pressing member 42m is embedded in a transverse hole 42h that opens in a direction orthogonal to the sliding direction of the second axis 42. The pressing member 42m is subjected to force towards the outer surface in the radial direction of the second axis 42 by the elastic member 42n. Therefore, when the fitting insertion part 42a is inserted into the sliding retaining hole 41h, the pressing member 42m can abut against the inner surface of the sliding retaining hole 41h.

[0071] Furthermore, the first shaft 41 is structured to connect the retaining hole structure 41a and the knee-side connecting portion 41b. The retaining hole structure 41a forms a sliding retaining hole 41h, and the knee-side connecting portion 41b is connected to the upper end portion 51b on the lower leg portion 50 side to form the knee joint portion. Moreover, the retaining hole structure 41a is proportionally divided into two parts, and is rotatably connected relative to the connecting protrusion 41c protruding from the upper end of the knee-side connecting portion 41b. Furthermore, the proportionally divided parts of the retaining hole structure 41a are fastened by screws 82 or the like, but the part with the screws 82 is configured as the aforementioned protruding guide portion 41d.

[0072] Figure 7 It is along Figure 2 The cross-sectional view of the YY line portion is a cross-sectional view showing the shorter state of the skeleton portion 40a. Figure 8 It is a sectional view along the YY line, showing the longer section of the skeleton 40a.

[0073] In the shortest state of the skeletal portion 40a, such as Figure 7As shown, the fitting insertion part 42a is inserted to its deepest point within the sliding retaining hole 41h. In this case, the locking protrusion 42p, which protrudes from the front end face of the pressing member 42m, is embedded in the first locking recess 41p. This maintains the shorter state of the skeleton part 40a. Furthermore, in this shorter state of the skeleton part 40a, the peripheral edge 43e of the outer shell part 43 is positioned close to the upper connecting part 42j.

[0074] On the other hand, in the longest state of the skeletal portion 40a, such as Figure 8 As shown, the fitting insertion portion 42a is inserted to its shallowest extent within the sliding retaining hole 41h. In this case, the locking protrusion 42p of the pressing member 42m is embedded in the second locking recess 41q provided on the opening side of the sliding retaining hole 41h. As a result, the skeleton portion 40a is maintained in a longer state.

[0075] Figure 9 This is a side view showing the state in which the outer shell 43 is in its initial state (reference state) and the thigh 40 is raised forward while the frame 40a is shorter.

[0076] When performing a bending operation to lift the thigh 40 forward, such as Figure 9 As shown, when bending operation (rotation around axis CL3) is performed while keeping the peripheral edge 43e of the outer shell 43 close to the upper connecting part 42j, the peripheral edge 43e and the lower edge 2e of the body 2 come into contact in the early stage of bending, and the bending angle does not become too large.

[0077] Figure 10 This is an enlarged front view of the thigh portion 40, showing the state in which the outer shell portion 43 has rotated since the initial state (reference state). Figure 11 This is a side view showing the state in which the outer shell 43 is rotated and the thigh 40 is lifted forward.

[0078] Before performing leg flexion step 8, as Figure 10 As shown, for example, an operation is performed to rotate the outer casing 43 approximately 90 degrees. Thus, when the outer casing 43 is rotated, the peripheral portion 43e on the inner side of the bent thigh portion 40 is pulled away from the lower edge portion 2e. That is, the peripheral portion 43e, configured to change position in the direction of the axis CL1, is in a state where the portion that moves backward toward the knee relative to the lower edge portion 2e is bent inward. In this state, as... Figure 11 As shown, the shell is bent until the peripheral portion 43e contacts the lower edge 2e of the body portion 2 (rotation about the axis CL3). In this case, the bending angle is compared with the bending action before the outer shell portion 43 rotates. Figure 9 Compared to the state shown, the bending angle is larger.

[0079] Furthermore, the rotation angle of the outer shell 43 is described as approximately 90 degrees, but there is no limitation. The position of maximum bending (the position where the thigh 40 can be bent to the maximum) is affected by the shape of the adjacent lower edge 2e.

[0080] Figure 12 This is a front view showing the state in which the skeleton part 40a is stretched.

[0081] like Figure 12 As shown, when the skeleton portion 40a is lengthened, the distance between the peripheral portion 43e and the lower edge portion 2e increases. Furthermore, when the outer shell portion 43 is rotated 90 degrees to the right as shown in the figure, the distance between the peripheral portion 43e and the lower edge portion 2e on the inner side (front side) of the bending direction further increases.

[0082] Figure 13 This is a side view showing the state in which the thigh part 40 is raised forward while the skeleton part 40a is extended.

[0083] As described above, when a bending operation is performed while rotating the outer shell portion 43 in conjunction with the operation of stretching the skeleton portion 40a, such as Figure 13 As shown, the bending angle of the thigh portion 40 is very large. Furthermore, in this case, the flat portion 42k of the connecting base 42b of the skeleton portion 40a is significantly exposed. Therefore, bending (rotation) is possible until the connecting base 42b contacts the lower edge 2e. Furthermore, as... Figure 13 As shown, even with the thigh 40 bent significantly forward, it can still rotate around the axis CL2 of the upper connecting part 42j, causing the thigh 40 to extend laterally (to the right) towards the torso part 2. This further increases the bending angle.

[0084] As described above, in one embodiment of the present invention, the outer shell portion 43 is configured to rotate relative to the frame portion 40a in its outer peripheral direction, thereby enabling the interference position between the components adjacent to the outer shell portion 43 to change, for example, expanding the permissible range of the connection orientation (bending angle, etc.) between the torso portion 2 and the leg portion 8.

[0085] In this configuration, the peripheral portion 43e of the outer shell portion 43 varies in the direction of the axis CL1, thereby enabling the position of interference between the components adjacent to the outer shell portion 43 to change.

[0086] In this configuration, the length of the skeleton portion 40a can be extended or retracted relative to the length of the outer shell portion 43 in the direction of the axis CL1, thereby changing the distance between the outer shell portion 43 and the body portion 2 and preventing interference between the peripheral portion 43e of the outer shell portion and the body portion 2.

[0087] In the skeleton part 40a of this form, the second shaft 42 can slide and move under the guidance of the sliding retaining hole 41h of the first shaft 41, so the length of the skeleton part 40a can be changed.

[0088] In this configuration, the second shaft 42 can slide while abutting against the inner surface of the sliding retaining hole 41h due to the pressing member 42m, thus eliminating wobble between the second shaft 42 and the sliding retaining hole 41h. Consequently, the first shaft 41 and the second shaft 42 can extend and retract smoothly without wobble.

[0089] In this configuration, a pair of circumferential guide walls 43c provided on the inner circumferential surface 43is of the outer shell portion 43 are rotatably guided by the protruding guide portion 41d of the skeleton portion 40a, thus allowing the outer shell portion 43 to rotate smoothly. Furthermore, since the guide portion 41d is embedded between the pair of guide walls 43c, the axial position between the outer shell portion 43 and the skeleton portion 40a can be restricted (positioned).

[0090] In this configuration, the connection between the first shaft 41 and the second shaft 42 can be restricted to a position where they do not disengage from each other by engaging between the edge guide wall 43f of the outer casing 43 and the flange portion 42f of the second shaft 42. Therefore, no special structure is needed between the two shafts 41 and 42 to maintain their connection, thus simplifying the connection structure.

[0091] In this embodiment, the outer surface of the connecting base 42b of the connecting portion of the skeleton part 40a that connects to the body part 2 has a flat portion 42k, thereby enabling the flat portion 42k to suppress interference with adjacent components and expand the range of motion of the connecting portion.

[0092] In this embodiment, during the engagement of the sliding retaining hole 41h and the fitting insertion part 42a, the locking protrusion 42p provided on the front end face of the pressing member 42m engages and engages with the first locking recess 41p and the second locking recess 41q provided on the inner surface of the sliding retaining hole 41h. Therefore, for example, the shortest connection state and the longest connection state of the skeleton part 40a can be maintained.

[0093] The present invention has been described above in one aspect, but the invention can be modified appropriately within the scope of its technical concept. For example, in this aspect, the movable structure of the thigh 40 has been described, but the movable structure of the toy of the present invention is not limited thereto; for example, the same movable structure can also be used for the upper arm.
