DETAILED DESCRIPTION

[0061] Hereinafter, referring to Figures 1 to 14 An embodiment showing one technical solution of the present application is described.

[0062] Figure 1 A perspective view showing one embodiment of a toy provided with the movable structure of the present application.

[0063] As Figure 1 shown, the toy 100 has a head portion 101, a torso portion 102 (torso), and a tail portion 103, and is a toy that imitates a hypothetical robot provided with four limb portions 105 installed in the torso portion 102. For example, the toy 100 imitates a hypothetical combat weapon capable of attaching and changing armaments and armor, and has a mechanical structure. In the toy 100, the movable structure 1 described later is applied to the limb portions 105. Further, for example, an armament member 104 capable of swinging back and forth or the like is installed outside (upper end side in the drawing) of the installation portion of each limb portion 105.

[0064] Figure 2 A perspective view of Figure 1 the left front leg in the toy 100 shown. Figure 3This is an exploded perspective view showing the first movable part 10, the second movable part 20, and the third movable part 30 disassembled. Furthermore, in the toy 100, the right foreleg and the left foreleg are symmetrical and have the same structure, therefore description is omitted. Additionally, the illustration shows the weapon member 104 with the limb part 105 removed.

[0065] like Figure 2 As shown, the movable structure 1 is configured to be connected to the torso 102 via the torso connection portion 50, and is capable of moving like a joint along the rotation axes CL1, CL2, and CL3. For example, the movable structure 1 includes: a first movable portion 10 extending upward and downward in the figure, which is capable of rotating about a first axis 14 extending in a first direction (along the direction of the rotation axis CL1); a second movable portion 20 extending upward and downward, which is connected to the top end of the first movable portion 10 and is capable of moving in conjunction with the first movable portion 10; and a third movable portion 30 extending upward and downward, which is connected to both the first movable portion 10 and the second movable portion 20 in a manner that allows them to rotate relative to both the first movable portion 10 and the second movable portion 20.

[0066] Here, in Figure 2 and Figure 3 In the movable structure 1 of the front leg shown, the first movable part 10, the second movable part 20 and the third movable part 30 are provided in a state of being connected above and below. For the description of the same structural elements in the upper and lower pairs, the same reference numerals are used and the description is omitted as appropriate.

[0067] like Figure 3 As shown, a first movable part 10, arranged around a rotation axis CL1, extends upward and downward around a pair of cylindrical hubs 11, which are rotatably penetrated by a first shaft 14. The hubs 11 are penetrated by the first shaft 14, for example, in contact with each other in a joint-like manner, and each of the two hubs 11 has a cylindrical columnar part 12 extending upward and downward around its rotation radius. A second movable part 20 is connected to the top end of the columnar part 12. More specifically, the first movable part 10 is configured as a pair of upper and lower members that can rotate around the first shaft 14 at a predetermined angle of intersection. Furthermore, the upper second movable part 20u (20) is connected to the torso 102 side to form the shoulder of the foreleg, and the lower second movable part 20d (20) forms a connection to the foot 40. In addition, the third movable part 30 is arranged obliquely relative to the columnar part 12, with one end mounted around the columnar part 12 of the first movable part 10 and the other end mounted to the second movable part 20, the details of which will be described later.

[0068] Furthermore, a movable range stop 18 is provided on the outer surface of the hub 11, which restricts the relative rotational position of adjacent hubs 11. A mounting protrusion 19 is provided on the movable range stop 18 for mounting the stop 15, which will be described later.

[0069] The extending direction of the columnar portions 12 is the direction of the leg axis CL4 (second direction) intersecting the rotation axis CL1 (first direction), and the leg axis CL4 of the upper side and the leg axis CL4 of the lower side form a predetermined angle (angle of the joint). Further, the two columnar portions 12 are joined to the two second movable portions 20u, 20d (20) in a manner that they can rotate with the respective leg axes CL4 as centers with respect to the two second movable portions 20u, 20d (20). In addition, the two second movable portions 20u, 20d (20) are substantially cylindrical members, and are disposed in a manner that the respective rotation axes CL2, CL3 are substantially parallel to the rotation axis CL1.

[0070] In the upper second movable portion 20u, a support shaft 20c on the rotation axis CL2 thereof is attached to the trunk connecting portion 50. In addition, the lower second movable portion 20d is connected to the foot portion 40, for example, via a foot connecting portion 20e. Further, the foot connecting portion 20e holds the foot portion 40 in a manner that it can perform up-and-down movement and rotational movement, for example, via a ball joint or the like (refer to Figure 6 ) that connects the foot portion 40, and the details thereof are omitted. In addition, a plurality of claw portions 41 are provided on the tip end side of the foot portion 40, and these claw portions 41 are also appropriately configured to be able to individually rotate up and down and left and right.

[0071] The turntable 13 that is integral with the columnar portion 12 is a circular configuration in which the turn surface 13e thereof is inclined at a predetermined angle θ (refer to Figure 4 ) with respect to the leg axis CL4 (second direction). Further, the one end side 33 of the third movable portion 30 is configured in a ring shape and is attached to the turn surface 13e of the turntable 13 in a manner that it can slide with respect to the turn surface 13e of the turntable 13, and the other end side 32 is joined to the engagement hole 22 of the second movable portion 20.

[0072] Figure 4 is an exploded perspective view for showing the attachment configuration of the third movable portion 30. Figure 5 is a perspective view showing a state in which the second movable portion 20 is separated from the first movable portion 10 and the third movable portion 30.

[0073] As shown in Figure 4 , the third movable portion 30 is configured by a pair of left and right split members 30L, 30R that engage in a manner that they sandwich the columnar portion 12 from the left and right directions. The one end side 33 of the main trunk portion 31 of the third movable portion 30, which is configured to have a thick wall, has a ring-shaped protruding wall 33a that protrudes inward in a ring shape so as to surround the turntable 13. On the other hand, a protruding shaft 32a is provided protruding on the other end side 32 of the main trunk portion 31, and a tip end spherical portion 32b is provided on the tip end of the protruding shaft 32a.

[0074] On the rotary disk 13, a guide groove 13g along the circumferential direction is provided on the outer peripheral surface. Thus, the third movable portion 30 is joined to the rotary disk 13 in a manner so as to be slidable around the columnar portion 12, with the annular protruding wall 33a being engaged with the guide groove 13g.

[0075] As described above, the second movable portion 20 is a substantially cylindrical member, as Figure 5 indicated, an attachment hole 20h is provided on the outer surface thereof, to which the top end 12b of the columnar portion 12 is joined in a rotatable manner. Further, on the second movable portion 20, a protruding wall 21 protruding in the radial direction of the second movable portion 20 and having a thick wall thickness is provided at a position adjacent to the attachment hole 20h. On this protruding wall 21, an engagement hole 22 in the form of an elongated hole having a circular cross section is provided, which is open in the same direction as the attachment hole 20h. Further, the top end spherical portion 32b is engaged with the engagement hole 22 in a slidable manner.

[0076] Figure 6 is a cross-sectional view of the X-X line portion. Figure 2

[0077] As Figure 6 indicated, at a position on the upper side than the rotation axis CL1, the third movable portion 30 is joined in a state having the above-described inclination θ, from the upper left side of the drawing toward the lower right side, with respect to the upper leg axis CL4 joining the second movable portion 20 and the first movable portion 10. On the other hand, the third movable portion 30 on the lower side than the rotation axis CL1 is joined in a state having the above-described inclination θ, from the lower left side of the drawing toward the upper right side, with respect to the lower leg axis CL4 joining the second movable portion 20 and the first movable portion 10. In this way, the portion having the rotation axis CL1 is configured as, for example, a joint portion in the substantially central portion of the upper and lower legs (front legs).

[0078] Figure 7 is an action explanatory view at the time of rotation of the first movable portion 10.

[0079] With respect to the twisting action for turning the leg, the action is explained in the case where the first movable portion 10 is rotated with respect to the upper and lower second movable portions 20 (only the upper single second movable portion 20 is shown in the drawing).

[0080] In a state before the rotation of the first movable portion 10, for example, as Figure 7 ​As shown, the tip ball portion 32b is located at the deepest side (upper side) of the engagement hole 22. Then, the first movable portion 10 is rotated in either direction to the left or right (in the direction of the arrow A in the drawing). When the swivel plate 13, which is disposed obliquely with respect to the leg axis CL4, is rotated by this rotation, the uppermost end portion 13t, which is located at the uppermost end of the swivel plate 13, moves slightly to the lower side. Due to the movement of the swivel plate 13, the third movable portion 30 moves downward (in the direction of the arrow B shown by a dotted line in the drawing). Along with this downward movement, the tip ball portion 32b moves to the opening side (lower side in the drawing) within the engagement hole 22. In addition, when the tip ball portion 32b has moved, the main body trunk portion 31 of the third movable portion 30 also moves in rotation, so that the protruding shaft 32a becomes in a state in which it is inclined with respect to the engagement hole 22 by an amount corresponding to the rotation, compared to the initial position.

[0081] Thus, even if the first movable portion 10 is rotated to become in a state in which the orientations of the first movable portion 10 and the second movable portion 20 are twisted, the third movable portion 30 maintains its connection state only by slightly changing the connection interval between the first movable portion 10 and the second movable portion 20.

[0082] Figure 8 is a perspective view showing a state of restriction of the twisting action.

[0083] In the case of performing the twisting action of swiveling the leg portions, as shown in Figure 8 , the first movable portion 10 is relatively rotated with respect to the second movable portion 20. That is, in the case of viewing the leg portions from above, the swivel is performed in a direction in which the rotation axis CL1 and the rotation axis CL2 intersect. At this time, the third movable portion 30 rotates together with the first movable portion 10 in a manner of being dragged by the swivel plate 13. However, the third movable portion 30, which has a deviation in rotational movement from the first movable portion 10, increases in frictional force, and the movement amount of this third movable portion 30 gradually decreases and stops rotating earlier than the first movable portion 10. Thus, the restriction of the rotation amount of the first movable portion 10, that is, the restriction of the twisting action can be set by the frictional force between the first movable portion 10 and the third movable portion 30. In addition, in the case in which the frictional force at this rotation is small, the relative movement amount of the first movable portion 10 with respect to the third movable portion 30 becomes large, but in this case, as shown in Figure 8 , the stopper 15 provided on the first movable portion 10 side and the end surface 31e of the main body trunk portion 31 can abut against each other to restrict the twisting action amount (swivel range).

[0084] In addition, in the linking portions of the pair of first movable portions 10, with respect to the movable range stopper 18 provided to the hub portion 11, for example, in the case in which the action has been performed in a manner of opening the upper and lower leg axes CL4 Figure 8When the movable range stoppers 18 are moved in the arrow C direction, the base portions 18b of the movable range stoppers 18 abut against each other. Thus, the moving angle of the upper and lower first movable portions 10 can be limited.

[0085] Figure 9 is a perspective view showing a twisted state of the left front leg to the outward side. Figure 2 is a perspective view showing a twisted state of the left front leg to the outward side.

[0086] In the movable structure 1 configured as described above, in addition to being able to perform the flexion and extension action of the joint portion, for example, as shown in Figure 9 , the leg portion can also be able to perform a twisting action. In this case, when the illustrated leg portion is viewed from above, the turning axis CL1 is turned in the counterclockwise direction with respect to the orientation of the turning axis CL2. Also, with respect to the turning axis CL3 of the ankle portion, it can also be configured in a twisted state that is further turned in the counterclockwise direction when viewed from above. In this way, the upper and lower first movable portions 10 are rotated together in an open manner with respect to the torso portion 102, thereby causing the foot portion 40 to open with respect to the torso portion 102 to a large extent. Also, it is also possible to perform an action of bending the foot portion 40 to the inward side (torso portion 102 side) in a manner opposite to that shown in Figure 9 . Also, in a case where the upper and lower first movable portions 10 are rotated in different directions, a more complex twisted state can be expressed.

[0087] Figure 10 is an exploded perspective view of the torso connecting portion 50 of the front leg, Figure 11 is a perspective view showing an opening action of the leg portion using the torso connecting portion 50 of the front leg.

[0088] As shown in Figure 10 , the torso connecting portion 50 is provided with a transverse connecting portion 52, whose one end mounting portion 54 is mounted to the torso portion 102, and a longitudinal connecting portion 51, which is pivotally supported to the support shaft portion 55 at the other end of the transverse connecting portion 52. Also, the support shaft 20c of the upper second movable portion 20u is connected to the connecting hole 56 of the longitudinal connecting portion 51. The transverse connecting portion 52 has, for example, a torso side connecting portion 52a having a pivot portion 52c, and a leg side connecting portion 52b having an insertion hole 52d into which the pivot portion 52c is inserted. Also, the leg side connecting portion 52b is connected to the torso side connecting portion 52a in a manner that it can rotate with respect to the torso side connecting portion 52a about the pivot portion 52c. By configuring the torso connecting portion 50 in this way, as shown in Figure 11 , the front leg portion can perform an action of opening with respect to the torso portion 102 to a large extent in the transverse direction (left side direction).

[0089] Figure 12 is a perspective view of the left rear leg in the toy shown in Figure 1 .

[0090] In Figure 12 the case of the left rear leg shown, aspects different from the front leg are the configuration of the torso connecting portion 60, the linking orientation of the upper and lower pair of first movable portions 10, and the length of the ankle linking portion 46 of the foot portion 40, and the like. The portions other than these are the same structure as the front leg described above. For example, in the case of the rear leg, the upper and lower pair of first movable portions 10 become the following structure: the linking site is located at a position further forward than the second movable portion 20 on the upper side, and the orientation with respect to the torso portion 102 is flipped front to back. Also, with respect to the torso connecting portion 60, rather than becoming a link structure as in the case of the front leg, it is constituted by one support member extending in the substantially front-to-back direction of the torso portion 102. In the rear leg thus constituted, with respect to the portions other than the torso connecting portion 60, the rear leg is constituted by the same structure as the front leg. Figure 11 The action of the rear leg, other than the opening action shown, can be set to the same action as the action of the front leg.

[0091] The configuration of the third movable portion 30 can also be changed as shown in Figure 13 and Figure 14 .

[0092] Figure 13 is a side view shown in partial cross section indicating a modification example of the third movable portion 30 in the movable structure 1, Figure 14 is Figure 13 a schematic perspective view of the third movable portion 30 shown.

[0093] Figure 13 The third movable portion 30 shown is, for example, a cylinder structure provided with a cylinder main portion 35 and a cylinder rod main portion 36. One end side (left side in the drawing) of the cylinder main portion 35 is linked to the protruding wall 17 on the first movable portion 10 side via a first movable side linking portion 35b, and a cylinder opening 35a is provided on the other end side of the cylinder main portion 35 toward the second movable portion 20 side. One end side (right side in the drawing) of the cylinder rod main portion 36 is linked to the protruding wall 21 on the second movable portion 20 side via a second movable side linking portion 36b. Also, a cylinder rod 36a protruding toward the cylinder main portion 35 side is inserted in the cylinder opening 35a.

[0094] In the case thus constituted, for example when the first movable portion 10 is rotated, the distance between the protruding wall 21 on the second movable portion 20 side and the protruding wall 17 on the first movable portion 10 side changes. At this time, the cylinder rod 36a moves within the cylinder opening 35a, and in conjunction therewith, the interval between the cylinder main portion 35 and the cylinder rod main portion 36 changes. Thus, the elastic force and the action at the time of extension and contraction of the third movable portion 30 can be controlled using the frictional force between the cylinder rod 36a and the cylinder opening 35a, the in-and-out situation of the air within the cylinder opening 35a, and the like.

[0095] As Figure 14As shown, the cylinder main body portion 35 and the cylinder rod main body portion 36 that constitute the third movable portion 30 are arranged on both sides in a manner that sandwiches the columnar portion 12. By being arranged in this manner, the third movable portion 30 alternately performs an action in which the interval between the cylinder main body portion 35 and the cylinder rod main body portion 36 on one side widens and the interval between the cylinder main body portion 35 and the cylinder rod main body portion 36 on the other side narrows. That is, the third movable portion 30 can perform an action like the muscles of the inside and outside.

[0096] As described above, in the present embodiment, in the movable structure of the toy that imitates the limbs of an animal, the first movable portion 10 that can perform a bending action like a joint by rotating around the first axis 14 extending in the first direction can be rotated in a direction in which the first axis 14 swings (in a second direction extending transversely to the first direction), and thus the joint vicinity can be rotated in a twisting manner. As a result, an action that closely resembles the action around an actual joint can be performed. In addition, an agile action like that of an animal can be reproduced. Figures 1 to 14 As described above, in the present embodiment, in the movable structure of the toy that imitates the limbs of an animal, the first movable portion 10 that can perform a bending action like a joint by rotating around the first axis 14 extending in the first direction can be rotated in a direction in which the first axis 14 swings (in a second direction extending transversely to the first direction), and thus the joint vicinity can be rotated in a twisting manner. As a result, an action that closely resembles the action around an actual joint can be performed. In addition, an agile action like that of an animal can be reproduced.

[0097] In the present embodiment, the third movable portion 30 links the first movable portion 10 and the second movable portion 20 in a manner in which the connection interval between the first movable portion 10 and the second movable portion 20 can be changed, and thus, for example, around the columnar portion 12 (axis in the length direction in which the leg bone extends) extending in the second direction as the second axis, the contraction and expansion of the muscles that contract in a manner that winds around the columnar portion 12 when the columnar portion 12 rotates can be expressed, and an action that closely resembles that of an actual animal can be performed.

[0098] In the present embodiment, the one-end side 33 of the third movable portion 30 is supported in a slidable manner to the outer periphery of the rotation surface 13e of the turntable 13, and thus the rotation of the columnar portion 12 can be permitted while maintaining the linkage of the one-end side 33 and the other-end side 32. As a result, the columnar portion 12 and the third movable portion 30 can perform a twisting action in a manner in which the relative positions in the axis direction of the columnar portion 12 shift.

[0099] Moreover, in the present embodiment, as a structure for changing the linking distance between the first movable section 10 and the second movable section 20 by the rotation of the first movable section 10, for example, the rotation surface 13e of the turntable 13 is inclined with respect to the columnar section 12 (second direction), so that in the case where the columnar section 12 is rotated, the third movable section 30 moves on the turntable 13 and moves in the length direction of the columnar section 12. As a result, even when the one end portion (knee of the leg) of the columnar section 12 is rotated in a manner to change the orientation, the linking of the third movable section 30 can maintain the linking state while changing the linking distance, in a manner to perform the flexion action like the muscle portion of an animal, for example, the rotation (twist) of the knee portion of the leg. In addition, it can also be configured so that the friction force becomes larger as the twist angle becomes larger, whereby the action of approaching the joint of an actual animal can be simulated.

[0100] In the present embodiment, the third movable section 30 is composed of a pair of divided members 30L, 30R engaged in a manner to sandwich the turntable 13, so that the inner and outer muscle shapes can be easily expressed. In addition, by being composed of a pair, the assembly property is good when the divided members 30L, 30R are assembled to the turntable 13.

[0101] In the present embodiment, the third movable section 30 has a cylinder structure that can be flexed at the middle in the length direction thereof, so that the rotation of the columnar section 12 of the first movable section 10 can be supported while being supported by the cylinder structure. In addition, by configuring the third movable section 30 with a pair of cylinder structures at positions sandwiching the columnar section 12 in the radial direction thereof, the inner and outer muscles can be expressed. In addition, the pair of cylinder structures of the third movable section 30 can alternately perform the flexion action when alternately performed in the rotation direction of the columnar section 12, and the action of approaching the muscle of an actual animal can be performed.

[0102] In the present embodiment, the first movable section 10 can limit the rotation range by the stopper 15 that can contact the one end of the third movable section 30. In addition, by limiting the relative position of the rotation of the third movable section 30 and the first movable section 10, the second movable section 20 and the other end side 32 can be prevented from being disengaged. Moreover, the components of the rotation portion can be protected.

[0103] In the present embodiment, the first movable section 10 is configured so that a pair of columnar sections 12 extend in a predetermined direction, so that the joint portion such as the knee, elbow can be simulated. In addition, by providing the structures that can independently perform the twist action above and below, for example, the leg portion above the knee can be rotated with respect to the trunk portion, on the other hand, the leg portion below the knee can also be freely rotated independently thereof. As a result, the action of approaching the actual animal can be performed.

[0104] In this embodiment, the movable range stopper 18 that limits the rotation angle in the direction around the axis of the first direction is provided to the pair of first movable portions 10, so that the movable range of the knee portion, for example, can be limited to perform an action close to that of an actual animal. In addition, by limiting the excessive rotation of the pair of first movable portions 10, the components of the rotation portion can be protected.

[0105] The above describes one embodiment of the present application, but the present application can be appropriately changed within the scope of the technical idea thereof. For example, in the above embodiment, the robot toy that imitates a quadruped animal is described, but is not limited thereto, and can be applied to a robot that walks on two legs, a robot that slithers like a snake, and the like, toys having various movable configurations. In addition, the present application is not limited to the leg portion, and can be applied to the wrist portion, the torso portion, the tail portion, and the like, movable portions.
