Description

[Technical Field]

[0001] The present invention relates to a moving toy. [Background technology]

[0002] Conventionally, there are known doll toys that can change shape. For example, in the shape-changing toy described in Patent Document 1, there is a toy in which the hands and feet of the doll body can be instantly stored inside a spherical head, and it is configured so that users can enjoy changing the shape.

[0003] Furthermore, there are conventional games such as dominoes and shogi toppling, in which multiple pieces are lined up so that they touch when they fall, and the players enjoy watching the pieces fall in a chain reaction. Regarding dominoes and the like, a toy such as the domino toppling toy described in Patent Document 2 is known in which a base and a piece that falls on the base are formed as one unit, and multiple units are connected to make the pieces fall in a continuous sequence. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 8-066562 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-191858 Summary of the Invention [Problem to be solved by the invention]

[0005] By the way, while shape-changing dolls are enjoyable to watch as they change form, they will not change form unless the user operates them. In addition, games such as dominoes and shogi toppling involve knocking down multiple pieces arranged in a chain reaction, but the pieces simply fall over, and the movements of each piece are simple.

[0006] The present invention has been made in light of the above-mentioned problems, and aims to provide a moving toy that can perform visually interesting shape changes in a chain reaction without the user having to perform sequential operations. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a motion toy having legs attached to a base placed on a flat surface, the legs being able to stand upright on the base, the lower end of the legs being rotatably supported by a base shaft provided on the base, and the range of rotation around the base shaft being limited to a predetermined range from an upright position toward the front, the upper leg members being able to stand upright above the lower leg members, a first rotating part rotatably supporting the lower end of the upper leg members and positioned behind the base shaft, and a second rotating part rotating the upper end of the lower leg members. The toy is equipped with an interlocking member having a second rotating part that rotatably supports the upper leg member and is positioned rearward of the base shaft part, and a tilting control member that rotates the upper leg member rearward from an upright position around the first rotating part when the lower leg member rotates forward from an upright position around the base shaft part, so that when multiple action toys are lined up in front of each other and the lower leg member of the action toy positioned at the rear rotates forward, the leg of the action toy positioned at the rear comes into contact with the leg of another action toy positioned in front of it. [Effects of the Invention]

[0008] This allows the moving toy of the present invention to undergo a series of visually interesting transformations without the user having to perform sequential operations. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the moving toy of the present invention will be described below based on Example 1 shown in the drawings. In this specification, the X-axis, Y-axis, and Z-axis are defined as shown in each drawing, and the X-axis in Fig. 1 is defined as the left-right direction (the positive X-axis direction is left, and the negative X-axis direction is right), the Y-axis is defined as the up-down direction (the positive Y-axis direction is up, and the negative Y-axis direction is down; sometimes referred to as the vertical direction), and the Z-axis is defined as the front-to-back direction (the positive Z-axis direction is back, and the negative Z-axis direction is front).

[0011] As shown in Figures 1 to 3, the moving toy 1 of Example 1 is composed of a main body 2 which is a doll that resembles a human body, and a base 3 that is placed on a horizontal surface and supports the main body 2.

[0012] The main body 2 can stand upright in a direction perpendicular to the horizontal plane on which the base 3 is placed, and includes a head 10 that resembles a human head, an upper body 20 that resembles a human upper body, and legs 30 that resemble a human lower body. That is, the legs 30 are attached to the base 3, and the upper body 20 is disposed above the legs 30.

[0013] The head 10 is fixed to the top of the upper body 20. The head 10 is composed of a cylindrical front head 11, whose front surface 11a facing forward is formed as a plane perpendicular to the front-to-rear direction, and a hemispherical occipital region 12, whose rear surface facing rearward is curved like a dome. The front head 11 is formed integrally with the front half body 21, which will be described later, and the occipital region 12 is formed integrally with the rear half body 22, which will be described later (see FIG. 5A). Therefore, the head 10, integrated with the upper body 20, can be separated into two parts in the front-to-rear direction.

[0014] As shown in FIG. 5A, the upper body 20 is made up of a front half body 21 and a rear half body 22, which are formed as two parts separable in the front-to-rear direction, and is formed by joining the front half body 21 and the rear half body 22. Here, the front half body 21 is formed with a front surface 21a facing forward, which is a plane that forms a right angle with the front-to-rear direction. The front surface 21a of the front half body 21 is flush with the front surface 11a of the head 10 (see FIG. 6). In addition, a left arm 23 is rotatably attached to the upper left side of the upper body 20, and a right arm 24 is rotatably attached to the upper right side of the upper body 20. A pair of notches 25 that recess the mating surfaces of the front half body 21 and the rear half body 22 are formed in the upper body 20 at the positions where the left arm 23 and the right arm 24 are attached.

[0015] A support shaft 26 (see FIG. 5A) is provided within each cutout portion 25, protruding from front half body 21 and having its tip portion fitted into a recess 22a formed in rear half body 22. Holes 26a through which support shafts 26 can pass are formed in upper end portion 23a of left arm 23 and upper end portion 24a of right arm 24. Left arm 23 and right arm 24 are pivotally supported by support shafts 26 passing through holes 26a with their upper ends 23a, 24a housed in cutout portions 25. With this structure, left arm 23 and right arm 24 can each rotate left and right relative to upper body 20.

[0016] Furthermore, both left arm 23 and right arm 24 hang down due to their own weight along the left and right side surfaces 20a of upper body 20. Abutment portions 27 that protrude laterally are formed on both the left and right side surfaces 20a of upper body 20. In addition, lower end portions 23b, 24b of left arm 23 and right arm 24 in a hanging state come into contact with abutment portions 27. Abutment portions 27 are portions that come into contact when left arm 23 and right arm 24 rotate, producing a light tapping sound.

[0017] 5A, a front recess 21b that is open toward the rear is formed in the lower part of front half body 21, and a rear recess 22b that is open toward the front is formed in the lower part of rear half body 22. A retaining member 28 is built into the lower interior of upper body 20 and is disposed between front half body 21 and rear half body 22. As shown in FIG. 6, retaining member 28 is retained within upper body 20 and simultaneously closes the openings of front recess 21b and rear recess 22b, respectively. As a result, a front bearing 28a is formed between front recess 21b and retaining member 28, and a rear bearing 28b is formed between rear recess 22b and retaining member 28.

[0018] As shown in Fig. 5B, the leg 30 is configured as a link mechanism combining multiple parts, with its lower end supported by the base 3 and its upper end attached to the upper body 20. That is, from the upright state shown in Figs. 1 and 2, the leg 30 of Example 1 rotates forward at its lower portion, bends at its midpoint, and rotates backward at its upper portion around the bent position, as shown in Fig. 3.

[0019] 5B, the leg 30 of the first embodiment includes an upper thigh member 31, an upper link member 32, a lower thigh member 33, a lower link member 34, and an interlocking member 35. The upper thigh member 31 and the interlocking member 35 are connected via a first shaft 36a, the lower thigh member 33 and the interlocking member 35 are connected via a second shaft 36b, and the upper link member 32 and the lower link member 34 are connected to the interlocking member 35 via a third shaft 36c. Furthermore, the lower thigh member 33 is connected to the base 3 via a fourth shaft 37a, and the lower link member 34 is connected to the base 3 via a fifth shaft 37b.

[0020] In the leg 30 of Example 1, the upper thigh member 31 and the upper link member 32 imitate the area from below the waist to the knee of a person, and the lower thigh member 33 and the lower link member 34 imitate the area from below the knee to the ankle of a person.

[0021] The upper thigh member 31 is disposed below the upper body 20 and can stand upright above the lower thigh member 33. The upper thigh member 31 has a left upper thigh portion 31a and a right upper thigh portion 31b aligned in the left-right direction, and a cylindrical first connecting shaft 31c connecting the upper portions of the left upper thigh portion 31a and the right upper thigh portion 31b. The first connecting shaft 31c extends in the left-right direction and is rotatably attached to the front bearing 28a (see FIG. 6). As a result, the upper end of the upper thigh member 31 is rotatably supported by the upper body 20.

[0022] Furthermore, shaft holes 31d are formed in the lower parts of the left upper leg portion 31a and the right upper leg portion 31b at positions facing each other in the left-right direction. The shaft holes 31d are through-holes that pass through the left upper leg portion 31a and the right upper leg portion 31b, and the first shaft 36a is press-fitted into the shaft holes 31d.

[0023] The left upper leg 31a and the right upper leg 31b each have a front surface 31f facing forward, which is formed as a plane that forms a right angle with the front-to-back direction when the legs 30 are in an upright position. When the legs 30 are in an upright position, the front surfaces 31f are flush with the front surface 11a of the head 10 and the front surface 21a of the front half body 21 (see FIG. 6).

[0024] Furthermore, the left upper thigh portion 31a and the right upper thigh portion 31b have open lower ends that face the lower thigh member 33 when the leg 30 is in an upright position. An upper contact surface 31j, which is a narrow flat surface that follows the outer shape, is formed on the periphery of the lower ends.

[0025] The upper link member 32 is disposed behind the upper thigh member 31 and includes a left upper link 32a and a right upper link 32b aligned in the left-right direction, and a cylindrical second connecting shaft 32c connecting the upper portions of the left upper link 32a and the right upper link 32b. The second connecting shaft 32c extends in the left-right direction and is rotatably attached to the rear bearing 28b (see FIG. 6). As a result, the upper end of the upper link member 32 is rotatably supported by the upper body 20 at a position rearward and below the upper end of the upper thigh member 31.

[0026] Furthermore, shaft holes 32d are formed at the lower ends of the upper left link 32a and the upper right link 32b at positions facing each other in the left-right direction. The shaft holes 32d are through-holes that pass through the upper left link 32a and the upper right link 32b.

[0027] The lower leg member 33 is disposed below the upper leg member 31 and is capable of standing upright relative to the base 3, with its lower end rotatably supported by a bearing 41 provided on the base 3. The lower leg member 33 has a left lower leg portion 33a and a right lower leg portion 33b aligned in the left-right direction, and a connecting portion 33c connecting the left lower leg portion 33a and the right lower leg portion 33b.

[0028] Furthermore, upper shaft holes 33d are formed at the upper ends of the left and right crus 33a and 33b at positions facing each other in the left-right direction, and lower shaft holes 33e are formed at the lower ends of the left and right crus 33a and 33b at positions facing each other in the left-right direction. The upper shaft holes 33d and the lower shaft holes 33e are through holes that pass through the left and right crus 33a and 33b. A second shaft 36b is press-fitted into the upper shaft hole 33d, and a fourth shaft 37a is press-fitted into the lower shaft hole 33e.

[0029] The left lower leg 33a and the right lower leg 33b each have a front surface 33f facing forward, which is formed as a plane that forms a right angle with the front-to-rear direction when the legs 30 are in an upright position. When the legs 30 are in an upright position, the front surface 33f is flush with the front surface 11a of the head 10, the front surface 21a of the front half body 21, and the respective front surfaces 31f of the left upper leg 31a and the right upper leg 31b (see FIG. 6). In addition, a contact member 33g that is semicircular in front view is formed at the lower end of the front surface 33f.

[0030] In addition, the bottom surfaces 33h of the left lower leg portion 33a and the right lower leg portion 33b (the surfaces facing the base 3 when the leg portion 30 is in an upright position) are formed as planes perpendicular to the vertical direction when the leg portion 30 is in an upright position, and the front corners are formed as convex curved surfaces centered on the lower shaft hole 33e (see Figure 4).

[0031] Furthermore, the left crus 33a and right crus 33b are formed with a lower contact surface 33j, which is a narrow, flat surface that follows the outer shape, at their upper ends that face the upper thigh member 31 when the leg 30 is in an upright position, and an insertion section 33k formed inward of the lower contact surface 33j. The insertion section 33k protrudes from the lower contact surface 33j, and its peripheral surface is inclined toward the inside of the left crus 33a or right crus 33b. When the leg 30 is in an upright position, the lower contact surface 33j comes into contact with the upper contact surface 31j, and the insertion section 33k fits into the lower end of the left crus 33a or right crus 33b.

[0032] Additionally, on the rear surfaces of the left crus 33a and the right crus 33b, engaging protrusions 33m are formed that protrude rearward when the leg 30 is in an upright position.

[0033] The lower link member 34 is disposed behind the crus member 33 and includes a left lower link 34a and a right lower link 34b aligned in the left-right direction, and a connecting portion 34c connecting the left lower link 34a and the right lower link 34b. Upper shaft holes 34d are formed in the upper portions of the left lower link 34a and the right lower link 34b at positions facing each other in the left-right direction, and lower shaft holes 34e are formed in the lower portions of the left lower link 34a and the right lower link 34b at positions facing each other in the left-right direction. The upper shaft hole 34d and the lower shaft hole 34e are through holes that pass through the left lower link 34a and the right lower link 34b. A fifth shaft 37b is press-fitted into the lower shaft hole 34e.

[0034] Furthermore, in the action toy 1 of Example 1, when the leg section 30 is assembled, the lower part of the upper link member 32 is inserted between the lower left link 34a and the lower right link 34b. At this time, the upper shaft holes 34d formed in the lower left link 34a and the lower right link 34b are arranged coaxially with the shaft holes 32d formed in the upper left link 32a and the upper right link 32b. Then, the third shaft 36c is press-fitted into the upper shaft hole 34d and rotatably passes through the shaft hole 32d.

[0035] The lower ends of the left lower link 34a and the right lower link 34b are formed with abutment protrusions 34g that protrude forward when the leg 30 is in an upright position. Furthermore, the left lower link 34a and the right lower link 34b are formed on their left and right side surfaces with a cylindrical interference protrusion 34j that surrounds the upper shaft hole 34d and a cylindrical interference protrusion 34h that surrounds the lower shaft hole 34e.

[0036] The interlocking member 35 is disposed in the center of the upper leg member 31, the upper link member 32, the lower leg member 33, and the lower link member 34, and has a first interlocking portion 35a, a second interlocking portion 35b, and a third interlocking portion 35c.

[0037] The first interlocking portion 35a is inserted between the left upper leg portion 31a and the right upper leg portion 31b, and has a first shaft holding hole 35d (first rotating portion) formed therein. The first shaft holding hole 35d penetrates the first interlocking portion 35a in the left-right direction and is positioned so as to overlap the shaft holes 31d formed in the left upper leg portion 31a and the right upper leg portion 31b when the leg portion 30 is assembled. A first shaft 36a is press-fitted into the shaft hole 31d and rotatably passes through the first shaft holding hole 35d. The first shaft holding hole 35d has an elongated cross section in a side view. Therefore, the upper leg member 31 is held movably and rotatably at the position of the first shaft holding hole 35d via the first shaft 36a.

[0038] The second interlocking portion 35b is formed below the first interlocking portion 35a and is inserted between the left crus 33a and the right crus 33b. The second interlocking portion 35b has a second shaft holding hole 35e (second rotating portion). The second shaft holding hole 35e is located below the first shaft holding hole 35d, penetrates the second interlocking portion 35b in the left-right direction, and is positioned coaxially with the upper shaft holes 33d formed in the left crus 33a and the right crus 33b when the leg 30 is assembled. The second shaft 36b is press-fitted into the upper shaft hole 33d and rotatably passes through the second shaft holding hole 35e. Therefore, the crus member 33 is rotatably held at the position of the second shaft holding hole 35e via the second shaft 36b.

[0039] The third interlocking portion 35c is formed at a position rearward of the first interlocking portion 35a and the second interlocking portion 35b and is inserted between the left upper link 32a and the right upper link 32b. A third shaft retaining hole 35f (third rotating portion) is formed in the third interlocking portion 35c. The third shaft retaining hole 35f is rearward of the first shaft retaining hole 35d and the second shaft retaining hole 35e and is disposed between the first shaft retaining hole 35d and the second shaft retaining hole 35e. The third shaft retaining hole 35f penetrates the third interlocking portion 35c in the left-right direction and is disposed coaxially with the shaft holes 32d formed in the left upper link 32a and the right upper link 32b and the upper shaft holes 34d formed in the left lower link 34a and the right lower link 34b when the leg portion 30 is assembled. The third shaft 36c press-fitted into the upper shaft hole 34d rotatably passes through the shaft hole 32d and the third shaft retaining hole 35f. Therefore, the upper link member 32 and the lower link member 34 are relatively rotatable at the position of the third shaft holding hole 35f via the third shaft 36c fixed to the lower link member 34. In other words, the third shaft holding hole 35f rotatably supports the lower end of the upper link member 32 and the upper end of the lower link member 34.

[0040] As shown in FIG. 5C, the base 3 has a flat base main body 40 that is approximately a regular hexagon in plan view, and the main body 2 is attached with predetermined corners facing in the front-to-rear direction.

[0041] The base main body 40 has a step 40a extending in the left-right direction formed midway in the front-rear direction. The base main body 40 has a height difference between an area in front of the step 40a and an area behind the step 40a, with the front area being lower than the rear area. As shown in FIG. 5C, the base 3 of Example 1 has a bearing 41, a connection hole 42 (engaged portion), a pair of auxiliary protrusions 43, a groove 44, a pair of recesses 45, and a pair of protrusions 46 formed in the area behind the step 40a. A connection protrusion 47 (engagement portion) is formed in the area in front of the step 40a, and a pair of engagement claws 48 are formed on the front edge. Furthermore, a pair of guide recesses 49 are formed on the back side of the area behind the step 40a (see FIG. 5D).

[0042] The bearing portion 41 is formed in approximately the center of the base body portion 40, protrudes from the surface of the base body portion 40, and has a front shaft hole 41a (base shaft portion) and a rear shaft hole 41b (second base shaft portion) that penetrate in the left-right direction. The rear shaft hole 41b is formed in a position rearward of the front shaft hole 41a and above the rear shaft hole 41b.

[0043] In the main body 2, the lower shaft hole 33e of the shank member 33 is positioned coaxially with the front shaft hole 41a, and the lower shaft hole 34e of the lower link member 34 is positioned coaxially with the rear shaft hole 41b. The fourth shaft 37a press-fitted into the lower shaft hole 33e rotatably passes through the front shaft hole 41a. Furthermore, the fifth shaft 37b press-fitted into the lower shaft hole 34e rotatably passes through the rear shaft hole 41b. Therefore, in the main body 2, the shank member 33 is rotatably held at the position of the front shaft hole 41a via the fourth shaft 37a, and the lower link member 34 is rotatably held at the position of the rear shaft hole 41b via the fifth shaft 37b.

[0044] The connection hole 42 is a through-hole that penetrates the base main body 40. The connection hole 42 is formed at the rear end rearward of the bearing portion 41 (front shaft hole 41a) and is located near a corner facing rearward. As will be described later, the connection hole 42 can engage with a connection protrusion 47 formed on another base 3.

[0045] The auxiliary protrusions 43 protrude from the surface of the base main body 40 and are formed on both the left and right sides of the bearing 41. The auxiliary protrusions 43 have a front surface 43a facing forward that forms an inclined surface tilted backward.

[0046] The groove 44 is a recess formed between the step 40a and the bearing 41 and extending in the left-right direction. A partition member 50 shown in FIG. 5E is removably inserted into the groove 44. The partition member 50 is a plate-shaped member, and stands upright from the base main body 40 when its lower end 51 is inserted into the groove 44. When the partition member 50 is attached to the base main body 40, it interferes with the bending legs 30 and restricts the bending of the legs 30. In other words, the legs 30 are bendable when the partition member 50 is not attached.

[0047] The pair of recesses 45 are recesses formed on the left and right sides of the bearing portion 41, behind the groove portion 44. Each recess 45 has a semicircular shape that curves backward in a plan view, and the bottom surface is formed so that it gradually becomes deeper toward the rear. When the leg 30 is bent, a contact body 33g formed on the front surface 33f of the crus member 33 engages with the recess 45. The contact body 33g interferes with the bottom surface of the recess 45, thereby restricting the crus member 33 from rotating forward.

[0048] A pair of protrusions 46 are formed between the step portion 40a and the groove portion 44, and protrude from the surface of the base main body portion 40. The distance between the pair of protrusions 46 is set to a dimension approximately equal to the width of the leg portion 30 in the left-right direction. When the leg portion 30 is bent, it fits between the pair of protrusions 46, and the lower leg member 33 interferes with the protrusions 46, thereby suppressing rattling.

[0049] The connection protrusion 47 is formed at the front end portion forward of the bearing portion 41 (front shaft hole 41a), and in this case, is formed near a corner portion facing forward. The connection protrusion 47 has a cylindrical shape protruding from the surface of the base main body portion 40. The connection protrusion 47 has a size that allows it to be inserted without rattle into the connection hole 42 formed in another base 3, and the other base 3 is supported so that it can rotate around the connection protrusion 47. Note that when the other base 3 rotates around the connection protrusion 47, it interferes with the step portion 40a, thereby restricting rotation of the base 3.

[0050] The pair of engagement claws 48 are formed on the front side edges of the base body 40, sandwiching a forward-facing corner, and protrude upward. The pair of guide recesses 49 allow the engagement claws 48 to fit into them, and extend along a circumference centered on the connection hole 42.

[0051] In the action toy 1 of Example 1, as shown in FIG. 6 , the center of the front bearing 28a and the center of the front shaft hole 41a are set on the same vertical line Lα, and the center of the rear bearing 28b and the center of the rear shaft hole 41b are set on the same vertical line Lβ in a side view. Furthermore, the front bearing 28a is formed in a position higher than the rear bearing 28b. Furthermore, the first shaft retaining hole 35d and the second shaft retaining hole 35e are positioned rearward of the front shaft hole 41a in a side view when the leg 30 is upright. The third shaft retaining hole 35f is positioned rearward of the rear shaft hole 41b in a side view when the leg 30 is upright. Furthermore, the third shaft retaining hole 35f is formed in a position lower than the first shaft retaining hole 35d and higher than the second shaft retaining hole 35e in a side view. Furthermore, the front shaft hole 41a is formed in a position lower than the rear shaft hole 41b in a side view.

[0052] In the action toy 1 of Example 1, when the leg 30 is in an upright position, the first line L1 and the second line L2 shown in FIG. 6 are parallel to each other in a side view, and the third line L3 and the fourth line L4 are parallel to each other in a side view. Here, the first line L1 is a line connecting the center of the front bearing 28a and the center of the rear bearing 28b. The second line L2 is a line connecting the center of the first shaft retaining hole 35d and the center of the third shaft retaining hole 35f. The third line L3 is a line connecting the center of the front shaft hole 41a and the center of the rear shaft hole 41b. The fourth line L4 is a line connecting the center of the second shaft retaining hole 35e and the center of the third shaft retaining hole 35f.

[0053] The bending motion of the legs 30 of the moving toy 1 of the first embodiment will be described below with reference to FIG. 7, which shows the states of the moving toy 1 in stages as the legs 30 are bent.

[0054] In the action toy 1 of Example 1, the leg 30, when in the upright state shown in Fig. 1 extending in the vertical direction, maintains the upright state unless an external force is applied. That is, when the leg 30 is in the upright state, the upper leg member 31 and the lower leg member 33 of the leg 30 are aligned in a straight line in the vertical direction as shown in Fig. 6, and the load due to the weight of the upper body 20 acts on the first connecting shaft 31c and the second connecting shaft 32c.

[0055] In contrast, first shaft retaining hole 35d that supports upper thigh member 31 is disposed rearward in side view from front bearing 28a to which first connecting shaft 31c is attached, as shown in Fig. 6. Furthermore, third shaft retaining hole 35f that supports upper link member 32 is disposed rearward in side view from rear bearing 28b to which second connecting shaft 32c is attached, as shown in Fig. 6. Therefore, the vector of a load acting vertically downward on first connecting shaft 31c passes in front of first shaft retaining hole 35d, and the vector of a load acting vertically downward on second connecting shaft 32c passes in front of third shaft retaining hole 35f.

[0056] As a result, the load due to the weight of the upper body 20 generates a moment in the opposite direction to the direction that rotates the upper thigh member 31 backward about the first axis 36a and the direction that rotates the upper link member 32 backward about the third axis 36c, thereby allowing the leg 30 to remain upright.

[0057] In the legs 30 of the moving toy 1 of Example 1, the bottom surfaces 33h of the left lower leg portion 33a and the right lower leg portion 33b are formed as planes that form a right angle with the up-down direction when the legs 30 are in an upright position. Therefore, when the legs 30 are in an upright position, the bottom surfaces 33h of the left lower leg portion 33a and the right lower leg portion 33b come into contact with the surface of the base main body 40 (see FIG. 4). Therefore, the moving toy 1 of Example 1 can restrict backward rotation of the lower leg member 33. Furthermore, the front corner of the bottom surface 33h is formed as a convex curved surface centered on the lower shaft hole 33e. Therefore, the moving toy 1 of Example 1 can allow forward rotation of the lower leg member 33.

[0058] Furthermore, in the moving toy 1 of Example 1, when the legs 30 are upright, the interference convexities 34h formed on the left lower link 34a and the right lower link 34b come into contact with the engagement convexities 33m formed on the left lower leg 33a and the right lower leg 33b. Therefore, the moving toy 1 of Example 1 can restrict the backward rotation of the legs 30 by the interference convexities 34h coming into contact with the engagement convexities 33m.

[0059] 7, the upright leg 30 starts to bend when an external force F acting from the rear to the front acts on the upright leg 30. The external force F may be input by pressing the leg 30 or by vibration occurring in the leg 30.

[0060] When the leg 30 receives the external force F, the lower link member 34 rotates forward around the rear shaft hole 41b of the bearing 41. Then, the lower leg member 33 is pushed forward by the lower link member 34, and the lower leg member 33 rotates forward around the front shaft hole 41a of the bearing 41.

[0061] The forward rotation of the lower leg member 33 and the lower link member 34 is restricted by the contact protrusions 34g formed on the left lower link 34a and the right lower link 34b interfering with the front surface 43a of the auxiliary protrusion 43, and by the contact bodies 33g formed on the left upper leg 31a and the right upper leg 31b engaging with the recesses 45. Therefore, the range of rotation of the lower leg member 33 about the front shaft hole 41a is limited to a predetermined range forward from the upright position.

[0062] As the lower link member 34 rotates forward, the interlocking member 35 moves forward. As a result, the position of the third shaft holding hole 35f, which supports the upper link member 32, moves forward of the front bearing 28a, which supports the first connecting shaft 31c. As a result, the vector of the load acting vertically downward on the second connecting shaft 32c passes behind the third shaft holding hole 35f. The vector of the load acting vertically downward on the second connecting shaft 32c acts in a direction that tends to rotate the upper link member 32 rearward about the third shaft 36c. As a result, the upper link member 32 rotates rearward about the third shaft holding hole 35f.

[0063] Furthermore, as the interlocking member 35 moves forward and the upper link member 32 rotates backward, the upper body 20 is pulled backward and the first connecting shaft 31c moves backward. As a result, the upper part of the upper thigh member 31 tilts backward and the upper thigh member 31 rotates backward around the first shaft holding hole 35d. In other words, the upper link member 32 corresponds to a tilt control member that rotates the upper thigh member 31 backward within a predetermined range from the upright position around the position of the first shaft holding hole 35d when the lower thigh member 33 rotates forward from the upright position around the front shaft hole 41a.

[0064] 7, the lower leg member 33 and the lower link member 34 of the leg 30 rotate forward, and at the same time, the upper leg member 31 and the upper link member 32 rotate backward, causing the leg 30 to bend at the position where the interlocking member 35 is provided (the middle part in the longitudinal direction).

[0065] Furthermore, in the moving toy 1 of Example 1, when the leg 30 bends, the first axis 36a moves back and forth within the first axis holding hole 35d of the interlocking member 35 to allow the upper leg member 31 and the lower leg member 33 to bend relative to each other. That is, in the main body 2, in the first half of the bending motion of the leg 30, the first axis 36a moves so as to arch the upper body 20 backward. Then, in the second half of the bending motion of the leg 30, the first axis 36a moves in a direction returning the upper body 20 to an upright position. Therefore, the moving toy 1 of Example 1 can prevent the upper body 20 from swinging significantly in the front-to-back direction when the leg 30 bends, and can maintain the upper body 20 in a nearly upright position from the start to the end of bending of the leg 30.

[0066] As described above, the moving toy 1 of Example 1 has a mechanism in which the first shaft holding hole 35d has an elongated cross section in a side view, and the first shaft 36a moves back and forth within the first shaft holding hole 35d as the leg 30 bends. This mechanism constitutes a means (posture maintaining means) for maintaining the posture of the upper body 20 in a nearly upright posture when the leg 30 is bent. This allows the posture of the upper body 20 to remain upright even when the leg 30 is bent so that the knee joint is bent. Placing a plurality of moving toys 1 configured in this manner in a row can provide a play experience in which the "knee-clap" motion, which will be described later, can be performed continuously. The posture maintaining means may be configured not only using the mechanism disclosed in Example 1, but also using other means. For example, the posture maintaining means may be configured by providing a self-sustaining, balanced position with the attachment position of the upper body 20 to the leg 30 as a fulcrum.

[0067] The magnitude of the swinging of the upper body 20 in the front-to-rear direction is determined by the inclination angle, relative to the horizontal plane, of the first straight line L1 that connects the front bearing 28a and the rear bearing 28b, which are the connecting parts between the upper body 20 and the leg 30. In other words, the greater the inclination angle of the first straight line L1 relative to the horizontal plane, the greater the swinging of the upper body 20 that occurs when the leg 30 is bent.

[0068] When the leg 30 is bent to its bending limit, the main body 2 of the action toy 1 of Example 1 assumes a form that mimics a slightly crouching human posture with the knee bent as if jutting out. The leg 30 is bent to its bending limit when the contact member 33g of the lower leg member 33 engages with the recess 45 and the upper leg member 31 interferes with the interference protrusion 34j.

[0069] Furthermore, as shown in Fig. 4, when a plurality of moving toys 1 are lined up in front of and behind each other, the legs 30 of the rear moving toy 1 are bent, and the bent legs 30 come into contact with the legs 30' of another moving toy 1' arranged in front (just ahead), and are set to a length that enables the legs 30' of the other moving toy 1' to be pushed forward from behind. That is, in the moving toy 1 of Example 1, when a plurality of moving toys 1 are lined up in front of and behind each other, as shown in Fig. 8, when the legs 30 of the rear moving toy 1 are bent, the legs 30' of the other moving toy 1' arranged in front of the moving toy 1 can be bent by pushing them from behind.

[0070] Note that "a state in which multiple action toys 1 are lined up in front of and behind" includes not only a case in which multiple action toys 1 are arranged on the same straight line along the front-to-back direction (see Figure 8), but also a case in which they are arranged in front of and behind each other with a predetermined range of offset from the straight line along the front-to-back direction (see Figure 10(B)).

[0071] With this configuration, when a plurality of action toys 1 of Example 1 are arranged in a row, as shown in FIG. 8 , and the leg 30 of the last action toy 1 is bent, the bending motion of the leg 30 is transmitted to the action toys 1 in front, causing a chain reaction of bending of the leg 30 forward. In other words, the action toy 1 of Example 1 reproduces the human movement known as "knee-cracking," in which, if a person standing behind bends his / her knee and pushes against the back of the knee of another person standing in front, the knee bends as the person is unable to support the body momentarily. Moreover, the action toy 1 of Example 1 can propagate the bending motion of the leg 30 from the rear to the front. As a result, the action toy 1 of Example 1 can perform a chain reaction of visually interesting shape changes without the user having to perform sequential operations.

[0072] In the action toy 1 of Example 1, the upper end of the upper thigh member 31 is rotatably supported by the upper body 20 disposed above the leg 30. The interlocking member 35 has a first shaft holding hole 35d, a second shaft holding hole 35e disposed below the first shaft holding hole 35d, and a third shaft holding hole 35f disposed rearward of the first shaft holding hole 35d and the second shaft holding hole 35e and between the first shaft holding hole 35d and the second shaft holding hole 35e. The tilt control member is formed by an upper link member 32 disposed rearward of the upper thigh member 31.

[0073] Here, the upper end of the upper link member 32 is rotatably attached to the upper body 20 at a position lower than the upper end of the upper thigh member 31. In addition, the lower end of the upper link member 32 is rotatably supported by the third shaft holding hole 35f of the interlocking member 35.

[0074] As a result, the moving toy 1 of the first embodiment can easily cause the leg 30 to bend with a simple structure.

[0075] In the action toy 1 of Example 1, the lower link member 34 is disposed behind the lower leg member 33, and the base 3 is formed with a rear shaft hole 41b at a position rearward of and above the front shaft hole 41a. The upper end of the lower link member 34 is rotatably supported by the third shaft holding hole 35f. The lower end of the lower link member 34 is rotatably supported by the rear shaft hole 41b.

[0076] Therefore, the action toy 1 of Example 1 can suppress the rotation of the upper body 20 that accompanies bending of the legs 30, and can move the upper body 20 in the vertical direction when the legs 30 are bent.

[0077] In the moving toy 1 of Example 1, the base main body 40 has a hexagonal shape in a plan view. Therefore, as shown in Fig. 9, when a plurality of bases 3 are arranged so that the sides of the hexagonal base main body 40 in a predetermined direction are in contact with each other, the bases 3 can be arranged in a honeycomb shape. Note that in Fig. 9, the main body 2 is omitted to make it easier to understand the state of the bases 3 when a plurality of moving toys 1 are arranged.

[0078] Furthermore, when multiple bases 3 are lined up with the sides of the hexagonal base main body 40 in a predetermined direction in contact with each other, the engaging claws 48 formed on the rear base 3 fit into and engage with the guide recesses 49 formed on the front base 3. This connects the bases 3 together, making it possible to line up the moving toys 1 at regular intervals without misalignment.

[0079] In addition, in the moving toy 1 of Example 1, when multiple bases 3 are lined up in front of and behind each other, the connecting protrusion 47 of the rear base 3 is inserted into the connecting hole 42 of the front base 3, as shown in Fig. 10A. This connects the bases 3 arranged in front of and behind each other, making it possible to line up the moving toys 1 at regular intervals without any misalignment. Note that the main body 2 is omitted in Fig. 10A to make it easier to understand the state of the bases 3 when multiple moving toys 1 are lined up.

[0080] Furthermore, in the moving toy 1 of Example 1, the base 3 arranged in the front and the base 3 arranged in the rear can rotate relatively within a certain range around the connection hole 42 and the connection protrusion 47. As a result, as shown in Fig. 10B, the moving toy 1 of Example 1 can tilt the arrangement direction of the bases 3 in the connected state relative to the front-to-rear direction. Note that in Fig. 10B, the main body 2 is omitted to make it easier to understand the state of the bases 3 when multiple moving toys 1 are arranged.

[0081] The angle range within which the arrangement direction of the moving toy 1 can be tilted is a range within which the base 3 arranged in the front does not interfere with the step portion 40a formed on the base 3 arranged in the rear. In the first embodiment, the arrangement direction can be tilted by 30° to the left and right around the front-to-rear direction.

[0082] Furthermore, when the arrangement direction of the moving toy 1 is tilted relative to the front-to-rear direction, the engagement claws 48 formed on the base 3 arranged at the rear enter into the guide recesses 49 formed on the base 3 arranged at the front. Here, since the guide recesses 49 extend along a circumference centered on the connection hole 42, the engagement claws 48 do not interfere with the base main body 40 even when the arrangement direction of the moving toy 1 is tilted relative to the front-to-rear direction.

[0083] Although the moving toy of the present invention has been specifically described above, the present invention is not limited to Example 1, and it goes without saying that modifications are possible within the scope of the technical idea of ​​the present invention.

[0084] That is, in the moving toy 1 of Example 1, an example in which the main body 2 imitates a human body is shown, but this is not limiting. The main body 2 only needs to have legs 30, and can imitate any shape, such as a standing animal or a non-human character.

[0085] Furthermore, the left upper leg 31a and the right upper leg 31b need only be attached to the upper body 20, and do not have to be connected by the first connecting shaft 31c. The left upper link 32a and the right upper link 32b also need not be connected by the second connecting shaft 32c, as long as they are attached to the upper body 20. Furthermore, the left lower leg 33a and the right lower leg 33b do not have to be connected by the connecting part 33c, and the left lower link 34a and the right lower link 34b do not have to be connected by the connecting part 34c.

[0086] In Example 1, since the main body 2 is modeled after a human body, the upper thigh member 31 and the like are configured to have two members (e.g., left upper thigh portion 31a and right upper thigh portion 31b) aligned in the left-right direction. However, depending on the shape that the main body 2 is modeled after, the upper thigh member 31 and the like may be a single member, or may be configured with three or more members aligned in the left-right direction.

[0087] Furthermore, in the action toy 1 of Example 1, the front surface 11a of the forehead 11, the front surface 21a of the front half body 21, the front surfaces 31f of the left upper leg 31a and right upper leg 31b, and the front surfaces 33f of the left lower leg 33a and right lower leg 33b are formed flush with each other. This allows, for example, a picture representing a face, such as eyes, a nose, and a mouth, or a picture of the face of an anime character, to be printed directly on the main body 2 using a printer or the like, or a sheet with a predetermined picture printed on it can be easily attached to the main body 2. Note that the front surface 11a of the forehead 11, etc., does not necessarily have to be a plane perpendicular to the front-to-rear direction, and does not necessarily have to be formed flush with other members.

[0088] Furthermore, in Example 1, an example was shown in which the engaging portion formed on the base 3 was the connecting protrusion 47 protruding from the base main body 40, and the engaged portion was the connecting hole 42 penetrating the base main body 40. However, the engaging portion and the engaged portion only need to be detachably engaged with each other, and for example, the engaging portion may be constituted by a through hole and the engaged portion may be formed by a protrusion. Also, the engaging portion and the engaged portion do not need to be formed on the base main body 40. [Explanation of symbols]
