Description

[Technical Field]

[0001] The present disclosure relates to biped robotic toys. [Background technology]

[0002] Conventionally, there have been many variations in robot toys, and various types have been proposed, such as robot toys that imitate humans who walk upright on two legs, and robot toys that imitate the forms of animals or insects. These robot toys may have a figure that acts as a person operating the robot, and various techniques have been proposed for where to position the figure that acts as a person operating the robot.

[0003] The location of the figure representing the person operating the robot can be on top of the robot toy or inside the torso, and the location not only affects the shape of the robot toy but also limits the range of motion of the joints that allow the robot toy to achieve various poses. Patent Document 1 discloses a technology in which the robot can be transformed from a running form to a flying form by rearranging the components that make up the toy body, and a figure representing the person operating the robot is housed inside the robot. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Application Publication No. 5-195 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with this technology, there are issues such as the fact that if a figure representing a person operating a bipedal robot toy is placed inside the torso of the bipedal robot toy, the torso itself becomes unnaturally large, it becomes difficult to secure space inside the torso to place a moving mechanism, and if the figure is placed above the bipedal robot toy, the range of movement of the arms and head of the bipedal robot toy is limited.

[0006] The objective of the present disclosure is to optimize the placement of a figure representing a person operating a robot, without making the torso of a bipedal robot toy unnaturally large, and to increase the range of motion of the arms, head, and legs to enable a variety of poses. [Means for solving the problem]

[0007] The bipedal robot toy of the present disclosure comprises a head, arms, an upper torso to which the head and arms are connected, two legs, and a lower torso to which the two legs are movably connected and which is movably connected to the upper torso, and a riding section is connected to the rear of the lower torso. [Effects of the Invention]

[0008] According to the present disclosure, the positioning of the figure representing the person operating the robot can be optimized, the torso of the bipedal robot toy can be made unnaturally large, and the range of motion of the arms, head, and legs can be expanded to enable a variety of poses.

[0020] [6] In the above [3], it is preferable that ball joints and joint receivers are provided for rotation around the first virtual axis, rotation around the second virtual axis, and rotation around the third virtual axis.

[0021] According to the present disclosure, by using a ball joint to properly maintain the position of a figure representing a person operating a bipedal robot toy, a structure with excellent space efficiency can be achieved.

[0022] [7] In the above [4] or [5], it is preferable that the lower torso and the upper torso are connected at a position shifted in a first direction from a position where the lower torso and the legs are connected, and the first shaft and the first bearing are provided at a position shifted in a direction opposite to the first direction from a position where the lower torso and the legs are connected.

[0023] According to the present disclosure, in a configuration that allows the riding part to move in three axes, by placing the upper torso in front and the riding part in the rear, sandwiching the legs between them, the weight balance between the bipedal robot toy and the figure representing the person operating it can be more appropriately achieved.

[0025] According to the present disclosure, in a configuration in which the movement of the riding part is achieved by a ball joint, by placing the upper torso in front and the riding part in the rear, sandwiching the legs, the weight balance between the bipedal robot toy and the figure representing the person operating it can be more appropriately achieved.

[0026] [9] In the above items [1] to [6], it is preferable that the lower torso section comprises a torso-connected lower torso section and a leg-connected lower torso section, and that the torso-connected lower torso section is movably connected to the upper torso section.

[0027] According to the present disclosure, by dividing the lower torso, the range of posing of the biped robot toy can be expanded.

[0028]

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

[0029] According to the present disclosure, it becomes possible to further expand the range of poses of a biped robot toy.

[0030]

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

[0031] According to the present disclosure, it becomes possible to expand the range of expressions possible using postures including the head of a bipedal robot toy.

[0032]

[0033] According to the present disclosure, it is possible to expand the range of expressions possible with postures including the arms of a biped robot toy while more appropriately balancing the weight.

[0034]

[13] In the above items [1] to [6], it is preferable that the head and the arms are movably connected to the upper torso.

[0035] According to the present disclosure, it is possible to expand the range of expressions possible with postures including the head and arms of a biped robot toy while more appropriately balancing the weight.

[0036]

[14] In the above [4], [5] or [7], the first shaft, the second shaft and the third shaft are each provided in a separate, divided section.

[0037] According to the present disclosure, in cases where a biped robot toy is sold as a so-called plastic model, the names of the parts when assembling the plastic model can be clarified. In other words, since each of the three axes is provided in a separate, divided portion, when explaining in an assembly manual or the like, only one axis is provided per part, making the explanation easier to understand.

[0038] [Details of the embodiments of the present disclosure] Specific examples of the biped robot toy of the present disclosure will be described below with reference to the drawings. In each drawing, for the sake of convenience, some of the components may be exaggerated or simplified. Furthermore, the dimensional proportions of each part may differ from drawing to drawing. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this specification, "parallel" and "orthogonal" do not only refer to strictly parallel or orthogonal, but also include roughly parallel or orthogonal within the scope of the effects of this embodiment.

[0039] [Embodiment 1] (Bipedal 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 30, a lower body 50, and a riding section 60. As shown in FIGS.

[0040] The head 10 and arms 20 are movably connected to the upper torso 30. The upper torso 30 and the lower torso 50 are movably connected. The lower torso 50 and the legs 40 are movably connected. In this embodiment, there is one head 10, two arms 20, and two legs 40, and the robot is in a form that walks upright, but the present invention is not limited to this.

[0041] (Head 10) As described above, the head 10 is movably connected to the upper torso 30 above the upper torso 30. More specifically, the head 10 can be moved upward or downward relative to the upper torso 30. In this specification, "upper" and "lower" refer to the upper and lower directions in FIG. 1 unless otherwise specified.

[0042] The head 10 can also be tilted leftward or rightward relative to the upper torso 30. In this specification, left and right refer to the left and right in FIG. 1 unless otherwise specified.

[0043] The head 10 can also be rotated relative to the upper body 30 about an axis in the vertical direction (an axis substantially parallel to a line passing through the center of gravity of the upper body 30 and the center of gravity of a lower body 50, which will be described later) in the state of the biped robot toy shown in Fig. 1. In this way, the head 10 can be freely moved relative to the upper body 30, so that the biped robot toy 1 can be made to take various poses and the range of expression can be expanded.

[0044] Although the embodiment shown in the drawings has only one head 10, there may be multiple heads as described above, and the heads may be connected to a location other than above the upper body. As a method for movably connecting the heads, a shaft and bearing may be used, or a ball joint may be used, and various other structures may be employed.

[0045] (Arm 20) 1 to 3 and as described above, the arms 20 are connected laterally to the upper torso 30 in a state in which they can move relative to the upper torso 30. More specifically, the arms 20 are connected to the upper side surfaces of the upper torso 30, and can move up and down and left and right, and can also rotate around the connected parts.

[0046] The method of movably connecting the arm 20 and the upper torso 30 may be various structures, such as using a shaft and bearing, using a ball joint, or constructing the connecting portion using a material such as rubber.

[0047] In this way, the arms 20 can be freely moved relative to the upper body 30, so that the biped robot toy 1 can be made to take a variety of poses, and the range of expression can be widened.

[0048] (Upper body 30) 1 to 3 and as described above, the head 10 and the arms 20 are movably connected to the upper torso 30. In addition, the lower torso 50, which will be described later, is also movably connected to the upper torso 30.

[0049] The upper torso 30 can be rotated relative to the lower torso 50 around an axis in the vertical direction (an axis approximately parallel to a 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 biped robot toy shown in Figure 1.

[0050] The method for movably connecting the upper body 30 and the lower body 50 may be a shaft and bearing, or a ball joint, and various other structures may be employed.

[0051] In this way, the upper body 30 can be freely moved relative to the lower body 50, so that the biped robot toy 1 can be made to take a variety of poses and the range of expression can be widened.

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

[0053] The lower torso 50 is movably connected to the upper torso 30, the legs 40, and a riding section 60 (described later).

[0054] (Body joint lower body part 51) The torso joint lower torso 51 can be rotated relative to the upper torso 30 around an axis in the vertical direction (an axis approximately parallel to a 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 biped robot toy shown in Figure 1.

[0055] The method for movably connecting the lower trunk section 51 and the upper trunk section 30 may be by using a shaft and bearing, or by using a ball joint, and various other structures may be employed.

[0056] In this way, the torso joint lower torso section 51 can be freely moved relative to the upper torso section 30, so that the biped robot toy 1 can be made to take a variety of poses and the range of expression can be widened.

[0057] (Leg joint lower torso 54) The leg-jointed lower torso portion 54 can be rotated relative to the torso-jointed lower torso portion 51 around an axis in the vertical direction (an axis approximately parallel to a line passing through the center of gravity of the head portion 10 and the center of gravity of the upper torso portion 30) in the state of the biped robot toy shown in Figure 1.

[0058] The method for movably connecting the trunk joint lower trunk section 51 and the leg joint lower trunk section 54 may be by using a shaft and bearing, or by using a ball joint, and various other structures may be employed.

[0059] In this way, the torso joint lower torso section 51 can be freely moved relative to the leg joint lower torso section 54, so that the biped robot toy 1 can be made to take a variety of poses and the range of expression can be widened.

[0060] (First bearing 58) The first bearing 58, by fitting with the first axis 61 described below, allows the riding section 60 described below to rotate relative to the lower torso 50 around an axis in the vertical direction (an axis approximately parallel to a 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 Figure 1.

[0061] In this way, the lower torso 50 can be freely moved relative to the riding section 60, so that the biped robot toy 1 and the figure 70 (described below) representing the person operating the robot can be made to take on a variety of poses, not only expanding the range of expression but also making it possible to properly balance the weight of the biped robot toy 1 and the figure 70.

[0062] (Ball Joint 59) The ball joint 59 allows the riding section 60 to rotate freely relative to the lower torso section 50 by fitting into a joint receiver 69 described below.

[0063] In this way, by using ball joints, it is possible to make the bipedal robot toy 1 and the figure 70 representing the person operating the bipedal robot toy 1 take on a variety of poses, not only expanding the range of expression but also making it possible to properly balance the weight of the bipedal robot toy 1 and the figure 70.

[0064] (legs 40) As shown in Figures 1 to 3, two legs 40 are movably connected to the lower torso 50. More specifically, one leg 40 is movably connected to the left and right of the leg-joined lower torso 54 in Figure 1.

[0065] The leg 40 and the leg joint lower body 54 can be movably connected using a shaft and bearing, a ball joint, or various other structures.

[0066] In this way, the legs 40 can be freely moved relative to the leg joint lower torso 54, so that the biped robot toy 1 can be made to take a variety of poses and the range of expression can be widened.

[0067] (Boarding section 60) As shown in Figures 2 to 4, 9 to 12, etc., the riding section 60 has a first axis 61, a second axis 62, a third axis 63, riding handholds 65, a riding main body 66, riding footrests 67, a riding seat 68, and a joint support 69. The first imaginary axis is parallel to the Z direction in the posture of the biped robot figure 1 in Figures 3 to 8. The second imaginary axis is parallel to the X direction in the posture of the biped robot figure 1 in Figures 3 to 8. The third imaginary axis is parallel to the Y direction in the posture of the biped robot figure 1 in Figures 3 to 8.

[0068] (first axis 61) The first axis 61 constitutes an axis in the vertical direction in the state of the biped robot toy shown in FIG. 1 (an axis substantially parallel to a line passing through the center of gravity of the head 10 and the center of gravity of the upper body 30).

[0069] More specifically, the first axis 61 is approximately parallel to a line passing through the center of gravity of the head 10 and the center of gravity of the lower torso 50, and the riding section 60 is connected to the lower torso 50 by the first axis 61 and a first bearing.

[0070] 1, the total load acting on the first shaft 61 and the first bearing does not change significantly even if the riding section 60 is displaced relative to the lower torso 50. Therefore, the load acting on the first shaft 61 and the first bearing, which play an important role in connecting the lower torso 50 and the riding section 60 among the three shafts, is reduced, and as a result, the entire biped robot toy 1 can have a robust structure.

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

[0072] By doing this, in a configuration that allows the riding section 60 to move in three axes, by placing the upper torso 30 in front (towards the viewer in Figure 1) and the riding section 60 in the rear (towards the reader in Figure 1) across the legs 40, the weight balance between the bipedal robot toy 1 and the figure 70 representing the person operating it can be more appropriately achieved.

[0073] (Second axis 62) The second axis 62 constitutes a rotation axis that is perpendicular to the first axis, which is substantially parallel to a line passing through the center of gravity of the head 10 and the center of gravity of the upper body 30 .

[0074] In order to explain the configuration of the biped robot toy 1, the riding section 60 and the figure 70 are omitted in Fig. 1, but the second axis 62 is an axis that allows the figure 70 to tilt to the left or right when viewed from the front of Fig. 1 (or to return from a tilted state) when the figure 70 is riding on the riding section 60. More specifically, the second axis 62 forms an axis that is parallel to the direction from the front to the back of the paper in Fig. 1 when the biped robot toy 1 is in the posture shown in Fig. 1.

[0075] By providing the second axis 62, for example, when the biped robot toy 1 tilts from the position shown in Figure 1, it becomes possible to keep the figure 70 representing the person operating the biped robot toy 1 in a non-tilted position, or in a position tilted in the opposite direction. This not only allows the biped robot toy 1 and the figure 70 representing the person operating the biped robot toy 1 to take on a variety of poses, widening the range of expression, but also makes it possible to properly balance the weight of the biped robot toy 1 and the figure 70.

[0076] (Third axis 63) The third axis 63 constitutes a rotation axis perpendicular to both the first axis 61, which is approximately parallel to a line passing through the center of gravity of the head 10 and the center of gravity of the upper torso 30, and the second axis 62, which is perpendicular to the first axis 61.

[0077] The third axis 63 is an axis that enables the figure 70 representing the person operating the biped robot toy 1 to move in the up and down direction in Fig. 2. More specifically, the third axis 63 constitutes an axis that is parallel to the direction from the front to the back of the paper in Fig. 2 when the biped robot toy 1 is in the posture shown in Fig. 2.

[0078] By providing the third axis 63, for example, when the biped robot toy 1 tilts from the position shown in Figure 2, it becomes possible to keep the figure 70 representing the person operating the biped robot toy 1 in a non-tilted position, or in a position tilted in the opposite direction. This not only allows the biped robot toy 1 and the figure 70 representing the person operating the biped robot toy 1 to take on a variety of poses, widening the range of expression, but also makes it possible to properly balance the weight of the biped robot toy 1 and the figure 70.

[0079] The first shaft 61, the second shaft 62, and the third shaft 63 may each be provided at a separate location.

[0080] By doing so, in cases where the biped robot toy 1 is sold as a so-called plastic model, the names of the parts when assembling the plastic model can be clarified. In other words, since each of the three axes is provided at a separate, divided portion, when explaining in an assembly manual or the like, only one axis is provided per part, making the explanation easier to understand.

[0081] (Boarding Handrail 65) The boarding handhold 65 is for a figure 70 impersonating a person operating the biped robot toy 1 to hold on to or for operating the biped robot toy 1 with his or her hands.

[0082] (Boarding body 66) The boarding main body 66 is the main body of the boarding section 60, and in the state of FIG. 2, extends downward from the boarding handholds 65 and is the portion where the boarding seat 68, which will be described later, is provided.

[0083] (Boarding footrest 67) The boarding footrest 67 is for a figure 70 representing a person operating the biped robot toy 1 to place his / her foot on, or for operating the biped robot toy 1 with his / her foot.

[0084] (Pass 68) The riding seat 68 extends rearward from the main body of the riding section 60 in the state of FIG. 2, and is a portion on which a figure impersonating a person operating the biped robot toy rides.

[0085] (Joint receiver 69) The joint receiver 69 is a part that engages with the ball joint 58 described above in order to movably connect the lower body section 50 and the riding section 60 together.

[0086] By adopting the configuration of the ball joint 58 and the joint receiver 69, it is possible to efficiently use space and make the biped robot toy 1 and the figure 70 representing the person operating the biped robot toy 1 take various poses, not only widening the range of expression but also making it possible to properly balance the weight of the biped robot toy 1 and the figure 70.

[0087] The lower torso 50 and the upper torso 30 are connected at a position shifted in a first direction (to the left in FIG. 2) from the position at which the lower torso 50 and the leg 40 are connected, and the ball joint 58 and the joint receiver 69 are provided at a position shifted to the right in FIG. 2, which is the direction opposite to the first direction (to the left in FIG. 2), from the position at which the lower torso 50 and the leg 40 are connected.

[0088] In a configuration in which the movement of the riding section 60 is achieved by a ball joint 58 and a joint receiver 69, by placing the upper torso 30 in front (towards the viewer in Figure 1) and the riding section 60 in the rear (towards the distance from the viewer in Figure 1) of the legs 40, the weight balance between the bipedal robot toy 1 and the figure 70 representing the person operating it can be more appropriately achieved.

[0089] (Figure 70) The figure 70 represents a person operating the biped robot toy 1, and rides on the riding section 60. More specifically, it represents the state of operating the biped robot toy 1 by sitting on the riding seat 68 and placing hands and feet on the riding handholds 65 and the riding footholds 67, respectively.

[0090] The effects of this embodiment will be described. The biped robot toy of the present disclosure includes: [1] It comprises a head 10, arms 20, an upper torso 30 to which the head 10 and arms 20 are connected, two legs 40, and a lower torso 50 to which the two legs 40 are movably connected and which is movably connected to the upper torso 30, and a riding section 60 is connected to the rear of the lower torso 50, and is in an upright bipedal form.

[0091] According to the present disclosure, the positioning of the figure 70 representing the person operating the robot is optimized, and the torso of the bipedal robot toy 1 is not made unnaturally large, and the range of motion of the arms, head, and legs is expanded, allowing for a variety of poses.

[0092] [2] In the above [1], the riding section 60 is movably connected to the lower body section 50.

[0093] According to the present disclosure, it is possible to properly balance the weight of the figure 70 representing the person operating the biped robot toy 1 and the biped robot toy 1.

[0094] [3] In the above [2], the riding section 60 can be rotated relative to the lower torso 50 around a first imaginary axis, the riding section 60 can be rotated relative to the lower torso 50 around a second imaginary axis perpendicular to the first imaginary axis, and the riding section 60 can be rotated relative to the lower torso 50 around a third imaginary axis perpendicular to the first and second imaginary axes.

[0095] According to the present disclosure, the position of the figure 70 representing the person operating the biped robot toy 1 can be kept constant regardless of the posture of the biped robot toy 1. In other words, even if the biped robot toy 1 is tilted forward or backward, or tilted to the side, the position of the figure 70 representing the person operating the biped robot toy 1 can be kept appropriate.

[0096] [4] In the above [3], a first shaft 61 and a first bearing are provided for rotation about a first imaginary axis, a second shaft 62 and a second bearing are provided for rotation about a second imaginary axis, and a third shaft 63 and a third bearing are provided for rotation about a third imaginary axis.

[0097] According to the present disclosure, the proper positioning of the figure 70 representing the person operating the bipedal robot toy 1 can be maintained by using a three-axis configuration with individual axes and bearings, resulting in a robust structure.

[0098] [5] In the above [4], the first axis 61 is approximately parallel to a line passing through the center of gravity of the head 10 and the center of gravity of the upper body 30, and the riding section 60 is connected to the lower body 50 by the first axis 61 and a first bearing.

[0099] According to the present disclosure, the load borne by the first axis 61 and the first bearing, which play the important role of connecting the lower torso 50 and the riding section 60, can be reduced, resulting in the entire biped robot toy 1 having a robust structure.
