[0025] According to the present disclosure, in a configuration in which the movement of the riding part is realized by a ball joint, by arranging the upper body part forward across the legs and the riding part backward, the weight balance between the two-legged robot toy and the figure playing the role of the person operating it can be made more appropriate.

[0026] [9] In the above [1] to [6], it is preferable that the lower body part includes a body-joined lower body part and a leg-joined lower body part, and the body-joined lower body part is movably connected to the upper body part.

[0027] According to the present disclosure, by dividing the lower body part, the posing width of the two-legged robot toy can be widened.

[0028]

[10] In the above [9], it is preferable that the leg-joined lower body part is movably connected to the body-joined lower body part.

[0029] According to the present disclosure, the posing width of the two-legged robot toy can be made wider.

[0030]

[11] In the above [1] to [6], it is preferable that the head is movably connected to the upper body part.

[0034]

[13] In the inventions according to [1] to [6] above, it is preferable that the head and the arms are connected to the upper body part in a movable state.

[0035] According to the present disclosure, while expanding the range of expressions in terms of the posture including the head and arms of the biped robot toy, it becomes possible to more appropriately achieve the weight balance.

[0036]

[14] In the inventions according to [4] or [5] or [7] above, each of the first axis, the second axis, and the third axis is provided one by one at a part that is separately divided as a separate body.

[0037] According to the present disclosure, in the case where the biped robot toy is sold as a so-called plastic model, it is possible to clarify the names of the parts (components) when assembling the plastic model. In other words, since each of the three axes is provided one by one at a part that is separately divided as a separate body, when explaining in an assembly instruction manual or the like, only one axis is provided for one part (component), and the explanation can be made easier to understand.

[0038] [Details of Embodiments of the Present Disclosure] A specific example of the biped robot toy of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be shown in an exaggerated or simplified manner. Also, the dimensional ratios of each part may be different in each drawing. Note that the present disclosure is not limited to these examples, and is shown by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims are included. In this specification, "parallel" and "orthogonal" include not only the strictly parallel and orthogonal cases, but also the cases that are generally parallel and orthogonal within the range where the effects of the present embodiment are achieved.

[0039] [Embodiment 1] (Biped Robot Toy 1) As shown in FIGS. 1 to 3, the biped robot toy 1 has a head 10, arms 20, legs 40, an upper body part 30, a lower body part 50, and a riding part 60.

[0040] The head 10 and the arms 20 are movably connected to the upper body 30. The upper body 30 and the lower body 50 are movably connected. The lower body 50 and the legs 40 are movably connected. In this embodiment, there is one head 10, and there are two arms 20 and two legs 40 respectively. Although it is in the form of bipedal walking, it is not limited to this.

[0041] (Head 10) As described above, the head 10 is connected above the upper body 30 in a movable state with respect to the upper body 30. More specifically, the head 10 can be moved upward or downward with respect to the upper body 30. In this specification, unless otherwise stated, the up and down directions refer to the up and down directions in FIG. 1.

[0042] The head 10 can also be tilted to the left and to the right with respect to the upper body 30. In this specification, unless otherwise stated, the left and right directions refer to the left and right directions in FIG. 1.

[0043] The head 10 can also be rotated about an axis in the up and down direction (an axis substantially parallel to the straight line passing through the center of gravity of the upper body 30 and the center of gravity of the lower body 50 to be described later) in the state of the bipedal robot toy shown in FIG. 1 with respect to the upper body 30. Since the head 10 can be freely moved with respect to the upper body 30 in this way, the bipedal robot toy 1 can be made to take various poses, and the range of expression can be expanded.

[0044] Although there is one head 10 in the form shown in the drawings, there may be a plurality as described above, or it may be connected to a part other than above the upper body. As a method of connecting in a movable state, an axis and a bearing may be used, or a ball joint may be used, and various structures can be adopted.

[0045] (Arms 20) As shown in FIGS. 1 to 3 and as described above, the wrist 20 is connected in the lateral direction of the upper body 30 in a state where it can be moved with respect to the upper body 30. More specifically, the wrist 20 is connected to the upper side surface of the upper body 30, can be moved up, down, left, and right, and can also be rotated about the connected portion as the center.

[0046] As a method of connecting the wrist 20 and the upper body 30 in a movable state, an axis and a bearing may be used, a ball joint may be used, or various structures such as forming the connecting portion with a member such as rubber can be adopted.

[0047] Since the wrist 20 can be freely moved with respect to the upper body 30 in this way, the two-legged robot toy 1 can be made to take various poses, and the range of expressions can be expanded.

[0048] (Upper body 30) As shown in FIGS. 1 to 3 and as described above, the head 10 and the wrist 20 are connected to the upper body 30 in a movable state. Further, the lower body 50 described later is also connected to the upper body 30 in a movable state.

[0049] The upper body 30 can be rotated about an axis in the vertical direction (an axis substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the upper body 30) in the state of the two-legged robot toy shown in FIG. 1 with respect to the lower body 50.

[0050] As a method of connecting the upper body 30 and the lower body 50 in a movable state, an axis and a bearing may be used, a ball joint may be used, and various structures can be adopted.

[0051] Since the upper body 30 can be freely moved with respect to the lower body 50 in this way, the two-legged robot toy 1 can be made to take various poses, and the range of expressions can be expanded.

[0052] (Lower body 50) As shown in FIGS. 1 and 3, the lower torso 50 has a torso-joint lower torso 51, a leg-joint lower torso 54, a first bearing 58, and a ball joint 59.

[0053] The upper torso 30, the legs 40, and a later-described riding part 60 are movably connected to the lower torso 50.

[0054] (Torso-joint lower torso 51) The torso-joint lower torso 51 can rotate about an axis in the vertical direction (an axis substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the upper torso 30) in the state of the bipedal robot toy shown in FIG. 1 with respect to the upper torso 30.

[0055] Note that, as a method of movably connecting the torso-joint lower torso 51 and the upper torso 30, an axis and a bearing may be used, or a ball joint may be used, and various structures can be adopted.

[0056] Since the torso-joint lower torso 51 can be freely moved with respect to the upper torso 30 in this way, the bipedal robot toy 1 can be made to take various poses, and the range of expression can be expanded.

[0057] (Leg-joint lower torso 54) The leg-joint lower torso 54 can rotate about an axis in the vertical direction (an axis substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the upper torso 30) in the state of the bipedal robot toy shown in FIG. 1 with respect to the torso-joint lower torso 51.

[0058] Note that, as a method of movably connecting the torso-joint lower torso 51 and the leg-joint lower torso 54, an axis and a bearing may be used, or a ball joint may be used, and various structures can be adopted.

[0059] Since the torso-joint lower torso 51 can be freely moved with respect to the leg-joint lower torso 54 in this way, the bipedal robot toy 1 can be made to take various poses, and the range of expression can be expanded.

[0060] (First bearing 58) The first bearing 58, by fitting with the first shaft 61 described later, can rotate the mounting part 60 described later with respect to the lower body part 50 about an axis in the vertical direction (an axis substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the upper body part 30) in the state of the two-legged robot toy shown in FIG. 1.

[0061] Since the lower body part 50 can be freely moved with respect to the mounting part 60 in this way, the two-legged robot toy 1 and the figure 70 described later that plays the role of the person operating the robot can be posed in various poses, and not only can the range of expression be expanded, but also the weight balance between the two-legged robot toy 1 and the figure 70 can be appropriately adjusted.

[0062] (Ball joint 59) The ball joint 59, by fitting with the joint receiver 69 described later, can rotate the mounting part 60 freely with respect to the lower body part 50.

[0063] In this way, by using the ball joint as well, the two-legged robot toy 1 and the figure 70 that plays the role of the person operating the two-legged robot toy 1 can be posed in various poses, and not only can the range of expression be expanded, but also the weight balance between the two-legged robot toy 1 and the figure 70 can be appropriately adjusted.

[0064] (Legs 40) As shown in FIGS. 1 to 3, two legs 40 are connected to the lower body part 50 in a movable state. More specifically, one leg 40 is connected to the left and right of FIG. 1 in the lower leg joint lower body part 54 in a movable state.

[0065] As a method of connecting the legs 40 and the lower leg joint lower body part 54 in a movable state, an axis and a bearing may be used, or a ball joint may be used, and various structures can be adopted.

[0066] Since the leg portion 40 can be freely moved with respect to the leg joint lower body portion 54 in this way, the two-legged robot toy 1 can be made to take various poses, and the range of expressions can be expanded.

[0067] (Ride-on part 60) As shown in FIGS. 2 to 4, FIGS. 9 to 12, etc., the ride-on part 60 includes a first axis 61, a second axis 62, a third axis 63, a ride-on handle part 65, a ride-on main body part 66, a ride-on footrest part 67, a ride-on seat part 68, and a joint receiver 69. The first virtual axis is parallel to the Z direction in the posture of the two-legged robot figure 1 in FIGS. 3 to 8. The second virtual axis is parallel to the X direction in the posture of the two-legged robot figure 1 in FIGS. 3 to 8. The third virtual axis is parallel to the Y direction in the posture of the two-legged robot figure 1 in FIGS. 3 to 8.

[0068] (First axis 61) The first axis 61 constitutes an up-down axis (an axis substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the upper body part 30) in the state of the two-legged robot toy shown in FIG. 1.

[0069] More specifically, the first axis 61 is substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the lower body part 50, and the ride-on part 60 is connected to the lower body part 50 by the first axis 61 and the first bearing.

[0070] Since the first axis 61 is provided in the up-down direction in the posture of the two-legged robot toy 1 in FIG. 1, even if the ride-on part 60 is displaced with respect to the lower body part 50, the total load applied to the first axis 61 and the first bearing does not change significantly. Therefore, among the three axes, the load borne by the first axis 61 and the first bearing, which play an important role in connecting the lower body part 50 and the ride-on part 60, can be reduced, and as a result, the entire two-legged robot toy 1 can have a robust structure.

[0071] The lower body part 50 and the upper body part 30 are connected at a position shifted in the first direction (the left direction in FIG. 2) from the position where the lower body part 50 and the leg part 40 are connected. The first shaft 61 and the first bearing are provided at a position shifted in the right direction in FIG. 2, which is the direction opposite to the first direction (the left direction in FIG. 2), from the position where the lower body part 50 and the leg part 40 are connected.

[0072] By doing so, in a configuration where the movement of the riding part 60 is realized in three axes, by arranging the upper body part 30 forward (the front direction of the paper surface in FIG. 1) with the leg part 40 in between and the riding part 60 backward (the back direction of the paper surface in FIG. 1), the weight balance between the two-legged robot toy 1 and the figure 70 played by the person operating it can be made more appropriate.

[0073] (Second shaft 62) The second shaft 62 constitutes a rotation axis in a direction orthogonal to the first axis that is substantially parallel to the straight line passing through the center of gravity of the head part 10 and the center of gravity of the upper body part 30.

[0074] In FIG. 1, the riding part 60 and the figure 70 are omitted for the purpose of explaining the configuration of the two-legged robot toy 1. However, the second shaft 62 is an axis for realizing that when the figure 70 is riding on the riding part 60, the figure 70 is in a tilted state (or returns from the tilted state) when viewed from the front of FIG. 1. More specifically, the second shaft 62 constitutes an axis parallel to the direction from the front to the back of the paper surface of FIG. 1 in the state where the two-legged robot toy 1 is in the posture of FIG. 1.

[0075] By providing the second shaft 62, for example, when the two-legged robot toy 1 tilts from the state as shown in FIG. 1, it is possible to keep the figure 70 played by the person operating the two-legged robot toy 1 in a non-tilted posture or in a posture tilted in the opposite direction. By allowing the two-legged robot toy 1 and the figure 70 played by the person operating the two-legged robot toy 1 to take various poses, not only can the range of expression be expanded, but also the weight balance between the two-legged robot toy 1 and the figure 70 can be appropriately adjusted.

[0076] (Third shaft 63) The third axis 63 constitutes a rotation axis in a direction orthogonal to both the first axis 61, which is substantially parallel to the straight line passing through the center of gravity of the head 10 and the center of gravity of the upper body 30, and the second axis 62 orthogonal to this.

[0077] The third axis 63 is an axis for realizing the up-and-down movement of the figure 70, which represents a person operating the bipedal robot toy 1, in the vertical direction of FIG. 2. More specifically, the third axis 63 constitutes an axis parallel to the direction from the front to the back of the paper surface of FIG. 2 in the state where the bipedal robot toy 1 is in the posture of FIG. 2.

[0078] By providing the third axis 63, for example, when the bipedal robot toy 1 tilts from the state as shown in FIG. 2, it becomes possible to keep the figure 70, which represents a person operating the bipedal robot toy 1, in a non-tilted posture or in a posture tilted in the opposite direction. In addition to being able to make the bipedal robot toy 1 and the figure 70, which represents a person operating the bipedal robot toy 1, take various poses, not only can the range of expression be expanded, but also the weight balance between the bipedal robot toy 1 and the figure 70 can be appropriately adjusted.

[0079] The first axis 61, the second axis 62, and the third axis 63 may each be provided one by one in parts that are separately divided as separate bodies.

[0080] By doing so, in the case where the bipedal robot toy 1 is sold as a so-called plastic model, the names of the parts (components) when assembling the model can be clarified. In other words, since each of the three axes is provided one by one in parts that are separately divided as separate bodies, when explaining in an assembly instruction manual or the like, only one axis is provided for one part (component), making the explanation easier to understand.

[0081] (Ride handle part 65) The ride handle part 65 is for the figure 70, which represents a person operating the bipedal robot toy 1, to hold onto or operate the bipedal robot toy 1 by hand.

[0082] (Ride-on main body part 66) The ride-on main body part 66 is the main body part of the ride-on part 60, which extends downward from around the ride-on handle part 65 in the state of Fig. 2, and is the part where the ride-on seat part 68 described later is provided.

[0083] (Ride-on footrest part 67) The ride-on footrest part 67 is for a figure 70 pretending to be a person operating the two-legged robot toy 1 to hook the feet or operate the two-legged robot toy 1 with the feet.

[0084] (Ride-on seat part 68) The ride-on seat part 68 extends rearward from the main body part of the ride-on part 60 in the state of Fig. 2, and is the part where a figure pretending to be a person operating the two-legged robot toy rides.

[0085] (Joint receiver 69) The joint receiver 69 is the part that engages with the aforementioned ball joint in order to connect the lower torso part 50 and the ride-on part 60 in a movable state. 59 And is the engaging part.

[0086] Ball joint 59 By adopting the configurations of the ball joint and the joint receiver 69, it is possible to efficiently utilize space, allow the two-legged robot toy 1 and the figure 70 pretending to be a person operating the two-legged robot toy 1 to take various poses, not only expand the range of expressions, but also appropriately balance the weights of the two-legged robot toy 1 and the figure 70.

[0087] The lower torso part 50 and the upper torso part 30 are connected at a position shifted in the first direction (the left direction in Fig. 2) from the position where the lower torso part 50 and the leg part 40 are connected, and the ball joint 59 And the joint receiver 69 are provided at positions shifted in the right direction in Fig. 2, which is the direction opposite to the first direction (the left direction in Fig. 2), from the position where the lower torso part 50 and the leg part 40 are connected.

[0088] The movement of the ride-on part 60 is controlled by the ball joint 59In the configuration realized by the joint receiver 69, by arranging the upper body part 30 forward (in the direction of the front side of the paper in FIG. 1) with the leg part 40 sandwiched therebetween and the riding part 60 backward (in the direction of the back side of the paper in FIG. 1), the weight balance between the two-legged robot toy 1 and the figure 70 that plays the role of a person operating the same can be made more appropriate.

[0089] (Figure 70) The figure 70 plays the role of a person operating the two-legged robot toy 1 and rides on the riding part 60. More specifically, it represents a state of sitting on the riding seat part 68 and operating the two-legged robot toy 1 by hanging the hands and feet on the riding handrail part 65 and the riding footrest part 67 respectively.

[0090] The operation and effect of this embodiment will be described. The two-legged robot toy of the present disclosure [1] includes a head part 10, an arm part 20, an upper body part 30 to which the head part 10 and the arm part 20 are connected, two leg parts 40, and a lower body part 50 to which the two leg parts 40 are movably connected and which is movably connected to the upper body part 30. A riding part 60 is connected to the rear part of the lower body part 50, and it is in the form of upright bipedal walking.

[0091] According to the present disclosure, the arrangement of the figure 70 that plays the role of a person operating the robot is optimized, and various posturings are possible without unnaturally enlarging the body of the two-legged robot toy 1 and by expanding the movable ranges of the arms, head, and legs.

[0092] [2] In the one described in [1] above, the riding part 60 is movably connected to the lower body part 50.

[0093] According to the present disclosure, the weight balance between the figure 70 that plays the role of a person operating the two-legged robot toy 1 and the two-legged robot toy 1 can be appropriately achieved.

[0094] [3] In the case of the above [2], the riding part 60 can be rotated about a first virtual axis with respect to the lower body part 50, the riding part 60 can be rotated about a second virtual axis orthogonal to the first virtual axis with respect to the lower body part 50, and the riding part 60 can be rotated about a third virtual axis orthogonal to the first virtual axis and the second virtual axis with respect to the lower body part 50.

[0095] According to the present disclosure, the position of the figure 70 playing the role of the person operating the bipedal robot toy 1 can be kept constant regardless of the posture of the bipedal robot toy 1. In other words, even when the bipedal robot toy 1 is in a state of leaning forward or backward, or in a state of leaning sideways, the position of the figure 70 playing the role of the person operating the bipedal robot toy 1 can be properly maintained.
