Description

[Technical Field]

[0001] The present invention relates to a joint structure of a doll body. [Background technology]

[0002] As an example of a toy with movable parts, a doll body that can be made to take various poses like a human is known. For example, Patent Document 1 describes a toy that can be enjoyed by moving the movable parts. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-159139 Summary of the Invention [Problem to be solved by the invention]

[0004] Among the dolls with movable parts, those that are particularly popular among boys are those that recreate characters such as transforming heroes, soldiers, and large humanoid robots that appear in manga, anime, special effects movies, games, novels, etc. (hereinafter collectively referred to as "original works").

[0005] When users purchase a doll of a character that appears in an original work, they want to be able to pose it in the same way as they saw it in the original work. However, the range of movement of the movable parts of the dolls of characters that appear in the original work is narrow, and the reproduction of the pose is often incomplete. From the user's perspective, the insufficient flexibility of the movable parts makes it difficult to recreate the pose from the original work, which can be disappointing.

[0006] The problem to be solved by the present invention is to realize a joint structure that can improve the flexibility of the movable parts of a doll body. [Means for solving the problem]

[0007] One aspect of the present invention is a joint structure for a doll body in which the legs can swing in a predetermined swinging direction relative to a waist base, the joint structure comprising: a first swing link connected to the waist base and swingable in the swinging direction relative to the waist base; and a second swing link having one end connected to the first swing link and the other end connected to the leg and swingable in the swinging direction relative to the first swing link, wherein the other end can be pulled out from or inserted in stages from the waist by multi-stage swinging caused by a first swing in which the first swing link swings relative to the waist base and a second swing in which the second swing link swings relative to the first swing link.

[0008] Furthermore, depending on the position of the joint structure in the doll body, the other end may be displaceable to a position above or below the one end by the multi-stage swing when viewed from the front of the doll body.

[0009] Furthermore, specifically, the connection structure between the first swing link and the second swing link may be configured such that the first swing link has an arc-shaped elongated hole portion along the swing direction, the first swing link is located outside the waist base in the front view, the first swing link has a connection portion with the one end on a side surface on the waist base side, and the second swing link is located between the waist base and the first swing link, and the other end is connected to the leg through the elongated hole portion.

[0010] In addition, the waist base may have an arc-shaped groove along the swing direction on the side facing the first swing link, and the first swing link may have a convex portion on the surface facing the waist base that fits into the groove.

[0011] Further, the waist base has an arc-shaped groove along the swing direction on a side surface on the first swing link side, and the first swing link has a convex portion that fits into the groove on a surface facing the waist base, and the range of the first swing is determined within a range in which the convex portion can move relative to the groove, The second swing range may be determined within a range in which the other end portion can move relative to the slot portion.

[0012] Furthermore, the leg may have a thigh and a lower leg, the thigh may have an upper part and a lower part, the upper end of the upper part may be connected to the other end of the second swing link, and the lower part may be configured to be swingable in the swing direction relative to the upper part.

[0013] The lower leg portion may also have an upper leg part and a lower leg part, and the connecting surface between the upper leg part and the lower leg part may have an inclined surface that slopes in the front-to-back direction from the front-upper side to the rear-lower side, and the lower leg part may be rotatably connected to the upper leg part along the inclined surface.

[0014] The leg may also have a foot at its lower end, the foot having a heel, a central portion, a connecting part that connects the central portion to the heel so that it can be pulled out, and a toe that is connected to the central portion so that it can swing up and down.

[0015] Another embodiment is a doll body equipped with the above-described joint structure.

[0016] The doll body may also be configured to include an upper arm and a forearm connected to the upper arm so as to be able to swing, the forearm having an upper arm part and a hand part, the connecting surface between the upper arm part and the hand part having a front-to-rear inclined surface that slopes in the front-to-rear direction from the upper arm side on the rear side of the doll body's body to the hand side on the front side of the body, and the hand side part being rotatably connected to the upper arm side part along the front-to-rear inclined surface. [Effects of the Invention]

[0017] According to the present invention, it is possible to provide a joint structure for a doll body that can improve the flexibility of the movable parts. [Brief explanation of the drawings]

[0019] 1 is a front external view of a doll body 2 in an upright position, which is an example of an embodiment to which the present invention is applied. The directional indications by arrows shown in each figure indicate the up and down directions (Y-axis direction; positive direction is up) for the doll body 2, the front and back directions (Z-axis direction; positive direction is forward) for the doll body 2, and the left and right directions (X-axis direction; positive direction is left) for the doll body 2. Directions in the following explanation will be based on these directions.

[0020] The doll body 2 is a toy that reproduces as a three-dimensional object a character originally created from a manga, anime, special effects movie, game, novel, etc. The doll body 2 of this embodiment has a design that resembles a humanoid robot, and is a toy that is made by assembling parts for different body parts.

[0021] The doll body 2 includes a head 3, a torso 4, arms 5, and legs 6. The torso 4 has an upper chest 41, a central abdomen 42, and a lower waist 43. The basic form of the doll body 2 is a human-like form with the torso 4 at the center, a head 3 above it, arms 5 on each side, and two legs 6 below. In addition to this form, the doll body 2 may be fitted with a backpack-like attachment on its back (for example, a back vernier in the case of a robot weapon), wings on its back, or a tail. Any of these forms has the basic form of the doll body 2 of this embodiment, and can be considered a doll body of this embodiment.

[0022] The doll body 2 is a humanoid robot soldier that appears in manga and anime, and is designed based on the theme of an armored warrior. In particular, the doll body 2 is provided with a joint structure 100 in the waist 43, which improves flexibility and ensures sufficient freedom to raise the legs 6, allowing the user to play with the doll body 2 in poses similar to those in the original work.

[0023] Fig. 2 is a perspective external view of the joint structure 100. Fig. 3 is an exploded perspective view of the joint structure 100. The joint structure 100 is a structure that swingably connects the legs 6 to the waist 43. The joint structure 100 has a waist base 101, left and right first swing links 110 (meaning the positive and negative sides in the X-axis direction with the waist base 101 in between), left and right second swing links 120, and left and right thigh joints 130.

[0024] FIG. 4 is a partial cross-sectional view of the area around the waist base body 101 in the longitudinal direction. The waist base body 101 is a key part that connects the various parts of the waist region 43. As shown in FIGS. 2 to 4, an abdominal connecting hole 102 that fits with a protrusion provided on the abdomen 42 is provided in the upper part of the waist base body 101. On the upper outer periphery of the front, rear, left, and right sides of the waist base body 101, exterior mounting parts 103 are provided to mount a front waist exterior part 43f, a rear waist exterior part 43r, and left and right side waist exterior parts 43s, respectively. Furthermore, a link support part 104 is provided in the lower part of the waist base body 101 to connect and support the first swing link 110 and the second swing link 120.

[0025] The link support 104 is a section that extends below the waist base 101 and is a plate-like section that is thin in the left-right direction. The link support 104 has first swing shafts 105 on the left and right sides of the front side, and has first groove 106 and second groove 107 that are elongated holes that penetrate left and right at a position rearward of the first swing shaft 105, are long in the vertical direction, and are curved in an arc shape with the first swing shaft 105 as their center. The second groove 107 is elongated in the vertical direction at a position further rearward of the first groove 106, penetrates left and right, and is curved in an arc shape with the first swing shaft 105 as its center.

[0026] The first swing link 110 is connected to the waist base body 101 and is a link that can swing up and down along the YZ plane. Specifically, the first swing link 110 has a first swing bearing 111 that fits onto the first swing shaft 105 of the waist base body 101. When the first swing shaft 105 is fitted into the first swing bearing 111, the first swing link 110 is connected to the waist base body 101 so as to be able to swing.

[0027] The first swing link 110 has an elongated hole 112 that is arc-shaped and extends in the vertical direction along the YZ plane.

[0028] Of the two first swing links 110, one on the left and one on the right, one first swing link 110 (the right first swing link 110 in this embodiment) has three left and right connecting protrusions 113 (113a, 113b, 113c) on the surface facing the waist base body 101. The other first swing link 110 (the left first swing link 110 in this embodiment) has three left and right connecting holes 114 (114a, 114b, 114c) that fit into the left and right connecting protrusions 113, respectively, on the surface facing the waist base body 101.

[0029] The first left-right connecting protrusion 113a has an outer diameter that fits slidably into the first groove 106 of the link support part 104. The second left-right connecting protrusion 113b has an outer diameter that fits slidably into the second groove 107 of the link support part 104.

[0030] The two left and right first swing links 110 are connected to each other with the link support part 104 of the waist base body 101 sandwiched between them. Specifically, in this connection, the first left and right connecting protrusion 113a is inserted into the first groove 106 of the link support part 104 and fits into the first left and right connecting hole 114a. The second left and right connecting protrusion 113b is inserted into the second groove 107 of the link support part 104 and fits into the second left and right connecting hole 114b. The third left and right connecting protrusion 113c is fitted into the third left and right connecting hole 114c at a position outside the link support part 104, i.e., at a position that does not sandwich the link support part 104. The two left and right first swing links 110 can swing together around the first swing shaft 105. In this state, when the joint structure 100 is viewed from the front, the left and right first swing links 110 are positioned on the outsides of the left and right waist base body 101 (see FIG. 2).

[0031] The first swing link 110 also has a connecting portion 115 for connecting and pivotally supporting the second swing link 120. The connecting portion 115 is a second swing bearing formed of a through hole in the left-right direction.

[0032] The second swing link 120 has a second swing shaft 121 that protrudes in the left-right direction at one end (the end on the lower side in FIG. 3). The second swing link 120 is swingably connected to the first swing link 110 by fitting the second swing shaft 121 into a connecting portion 115 that abuts against the second swing bearing.

[0033] Furthermore, the second swing link 120 has, at the other end (the end on the upper side in FIG. 3), a third swing bearing 123 which is a recess (or hole) provided along the same direction as the second swing shaft 121. The outer diameter of the third swing bearing 123 is set to a dimension that allows it to fit into the elongated hole portion 112 of the first swing link 110 and slide.

[0034] The second swing link 120 is assembled to the first swing link 110 at a position sandwiched between the waist base body 101 and the first swing link 110, with the second swing shaft 121 fitted into the connecting portion 115 and the third swing bearing 123 fitted into and inserted through the elongated hole portion 112. The first swing link 110 is assembled to the waist base body 101 with the second swing link 120 assembled thereto. When the joint structure 100 is viewed from the front in this state (see FIG. 2), the second swing link 120 is located between the waist base body 101 and the first swing link 110.

[0035] The second swing link 120 connects the third swing bearing 123 to a thigh joint 130 to which the leg 6 is connected.

[0036] The thigh joint 130 is a movable part that connects the second swing link 120 and the leg 6. Specifically, the thigh joint 130 has a front base body 131 and a rear base body 132 that are rotatably connected by a shaft and bearing in the front-to-rear direction. A leg connecting rod 133 extends from the front base body 131, and a third swing shaft 134 that functions as a waist connecting rod extends from the rear base body 132. This third swing shaft 134 fits into the third swing bearing 123 of the second swing link 120.

[0037] Therefore, the thigh joint 130 is connected to the second swing link 120 so that it can rotate in the front-to-back direction with the third swing shaft 134 as a left-to-right axis, and the leg connecting rod 133 can swing on an axis that intersects the left-to-right direction, using the front-to-back axis that fits the front base 131 and rear base 132 together.

[0038] When the thigh joint 130 is assembled to the second swing link 120 and the leg 6 is connected to the thigh joint 130, the other end of the second swing link 120 is connected to the leg 6 through the long hole 112 of the first swing link 110. More specifically, the other end is connected to the leg 6 via the thigh joint 130.

[0039] Next, the operation of the joint structure 100 will be described. 5 to 8 are transition diagrams of the joint structure 100 for explaining the operation of raising the leg 6, and the transitions are made in the order of the drawing numbers. Note that in these drawings, some components are omitted and some parts are cut away to facilitate understanding. The thigh joint 130 and the leg 6 are also shown in perspective with long dashed lines. The shape of the leg 6 is also shown in a simplified manner.

[0040] FIG. 5 corresponds to a state in which the doll body 2 is standing upright. Focusing on the waist base body 101 and the first swing link 110, the first left-right connecting protrusion 113a is at the upper end of the elongated hole of the first groove 106, which is the upper limit of the range of relative movement for that protrusion with respect to the waist base body 101. The second left-right connecting protrusion 113b is at the upper end of the elongated hole of the second groove 107, which is also the upper limit of the range of relative movement for that protrusion. When viewed from the side and focusing on the relative positional relationship with the first swing shaft 105, both the first left-right connecting protrusion 113a and the second left-right connecting protrusion 113b are located above the first swing shaft 105.

[0041] Also, focusing on the first swing link 110 and the second swing link 120, the third swing bearing 123 is located at the upper end of the long hole of the long hole portion 112, and is at the upper limit of the relative movement range of the bearing with respect to the first swing link 110.

[0042] To raise the leg 6, first, as shown in FIG. 6, the first swing link 110 is rotated about the first swing shaft 105 relative to the waist base 101 to swing downward. This is called the "first swing." The first swing allows the first left-right connecting protrusion 113a to move to the lower end of the elongated hole of the first groove 106, which corresponds to the lower limit of the movable range of that protrusion. Also, the second left-right connecting protrusion 113b can move to the lower end of the elongated hole of the second groove 107, which corresponds to the lower limit of the movable range of that protrusion.

[0043] 7, the second swing link 120 is rotated about the second swing shaft 121 relative to the first swing link 110 to swing downward. This is called the "second swing." The second swing allows the third swing bearing 123 to move to the lower end of the elongated hole of the elongated hole portion 112, which corresponds to the lower limit of the range of movement of the third swing bearing 123 relative to the first swing link 110.

[0044] As a result, the multi-stage swing of the first swing and second swing causes the third swing bearing 123, the third swing shaft 134, and the thigh joint 130 to be gradually pulled out from the internal space of the waist 43, which is surrounded by the exterior parts (front waist exterior part 43f, rear waist exterior part 43r, and side waist exterior part 43s). In this state, the other end of the second swing link 120, i.e., the third swing bearing 123, is displaced from a position above one end of the second swing link 120, i.e., the second swing shaft 121, to a position below it, as viewed from the front of the doll body 2. Of course, by performing the first swing and the second swing in reverse order, the third swing bearing 123, the third swing shaft 134, and the thigh joint 130 can be gradually inserted back into their original positions within the waist 43.

[0045] 8, the thigh joint 130 and the leg 6 are rotated relative to the second swing link 120 around the third swing bearing 123, causing the leg 6 to swing forward until it abuts against the lower end of the front waist exterior part 43f. This is called the "third swing."

[0046] Because the third rocking bearing 123 is pulled out from the waist 43 by the multi-stage rocking of the first rocking and the second rocking, the rocking angle of the leg 6 by the third rocking relative to the waist 43 is much larger than when the third rocking bearing 123 is performed without pulling out from the waist 43 (by omitting the first rocking and the second rocking) (see FIG. 9). In other words, the joint structure 100 connecting the waist 43 and the leg 6 has improved flexibility compared to conventional art. For example, if the doll body 2 carries a gun-type assault weapon, the user can make the doll body 2 assume a knee-shooting pose, a prone shooting pose with one knee bent, a front kick or knee kick pose in a close combat scene, a pose with the leg raised to climb over an obstacle, and the like.

[0047] Next, the detailed structure of the leg portion 6 will be described. Fig. 10 is a side view showing a detailed configuration example of the leg 6 of the doll body 2. Fig. 11 is an exploded view of the same. Note that in these figures, some components are omitted and some parts are cut away to make it easier to understand.

[0048] The leg 6 has a thigh 7, a lower leg 8, a foot 9, an exterior knee part 10, and an interior knee part 11.

[0049] The thigh 7 further includes an upper thigh part 71 and a lower thigh part 72 .

[0050] The upper thigh part 71 further has a rod fitting portion 73 and a fourth swing shaft 74 . The rod fitting portion 73 is a hole into which the leg connecting rod 133 (see FIG. 3) of the thigh joint 130 is fitted so as to be rotatable about its axis, and functions as a bearing for the leg connecting rod 133. Therefore, the upper end of the thigh upper part 71 is connected to the third swing bearing 123 at the other end of the second swing link 120 via the thigh joint 130.

[0051] The fourth swing axis 74 is a protrusion that functions as an axis for swingably connecting the thigh lower part 72 to the thigh upper part 71, and is protruded outward to the left and right on each of the left and right sides of the lower end of the thigh upper part 71.

[0052] The thigh lower part 72 has a front lower part 75 that is in the front when the doll body 2 is in an upright position, and a rear lower part 76, and is assembled so that the thigh upper part 71 is sandwiched between them from the front and back.

[0053] 12 is a side view of the leg 6, showing a partial cutaway view of the thigh and the surrounding area, and an exploded view of the knee and the surrounding area. For ease of understanding, the outline of the thigh upper part 71 is shown by a dashed line.

[0054] The front lower part 75 has an opening 751 at the front upper part through which the front upper end of the thigh upper part 71 is exposed, and a front shaft guide groove 752 .

[0055] The front shaft guide groove 752 is a recessed portion carved into the left and right inner surfaces. The rear lower part 76 also has a rear shaft guide groove 761 carved into the left and right inner surfaces. The front shaft guide groove 752 and the rear shaft guide groove 762 are provided in opposing positions so that the insides of both grooves communicate when the front lower part 75 and the rear lower part 76 are assembled. When the front lower part 75 and the rear lower part 76 are assembled, the front shaft guide groove 752 and the rear shaft guide groove 762 form a guide groove into which the fourth oscillation shaft 74 slidably fits. Therefore, the thigh lower part 72 is configured to be swingable relative to the thigh upper part 71 about the fourth swing axis 74 along the YZ plane of the leg 6 (when the doll body 2 is in an upright position).

[0056] The rear lower part 76 of the thigh lower part 72 has fifth swing shafts 77 that protrude in left and right directions on both the left and right sides of the lower end. The fifth swing shaft 77 functions as an axis for the knee joint of the leg 6, and is provided behind the center of the front-to-back of the leg 6.

[0057] The lower leg portion 8 has an upper leg part 81 and a lower leg part 82. The former corresponds to the region on the gastrocnemius muscle side of the human body, and the latter corresponds to the region below the gastrocnemius muscle.

[0058] The upper lower leg part 81 is composed of two pieces: a left part 83 and a right part 84. The left part 83 and the right part 84 have, at the upper end portions on the opposing surfaces thereof, a fifth swing bearing 85 into which the fifth swing shaft 77 can be inserted, and an interlocking protrusion guide groove 86 into which the interlocking protrusion 12 of the knee internal part 11 can be inserted.

[0059] The knee internal part 11 is a cover that covers the front of the fifth swing shaft 77 and the fifth swing bearing 85, and is thick in the left-right direction and has a semicircular shape when viewed from the side. When the doll body 2 is in an upright position, the upper part of the knee internal part 11 is inserted into the internal space formed by the thigh lower part 72.

[0060] Additionally, a knee exterior part 10 is attached to the front of the upper lower leg part 81. The knee exterior part 10 corresponds in design to the "knee pad" of armor.

[0061] The upper crus part 81 and the lower crus part 82 are rotatably connected by the lower crus rotation shaft 87 by rotatably fitting a lower crus rotation shaft 87, which protrudes diagonally upward and backward from an upper inclined surface 821 (a surface whose normal faces diagonally upward and backward) of the lower crus part 82, into a lower crus rotation bearing hole 88 opened in a lower inclined surface 811 (a surface whose normal faces diagonally downward and forward) of the upper crus part 81. A protrusion is provided on the upper end of the lower crus rotation shaft 87, and this protrusion catches on the inside of the lower crus rotation bearing hole 88 to prevent it from coming off.

[0062] When the state in which the upper shin part 81 and the lower shin part 82 are connected is viewed from the side, the connection surface F1 between them (see FIG. 10; the mating surface between the upper slant surface 821 and the lower slant surface 811) can be said to have an inclined surface that slopes in the front-to-rear direction from the upper front to the lower rear when the doll body 2 is in an upright position. The lower shin part 82 is connected to the upper shin part 81 so as to be rotatable along this inclined surface.

[0063] Next, the operation of the leg 6 will be described. 13 to 15 are transition diagrams of the joint structure 100 for explaining the operation of raising the thigh of the leg 6, and the transitions are shown in the order of the figure numbers. Note that in these figures, some components are omitted and some parts are cut away to make it easier to understand.

[0064] When the first to third swings are performed, the legs 6 are swung up forward as shown in Figure 13. When the doll body 2 is in an upright position and facing forward, the front of the upper thigh part 71 comes into contact with the lower end of the front waist exterior part 43f of the waist 43, and is in an upper limit position where the third swing cannot be performed any further.

[0065] From this state, the thigh lower part 72 is further rotated on the fourth swing shaft 74 to swing upward relative to the thigh upper part 71 (at this time, the fourth swing shaft 74 rotates while sliding from the lower end to the upper end within the guide groove in the thigh lower part 72, causing the thigh upper part 71 to swing relative to the thigh lower part 72), and as shown in Figure 14, the thigh 7 is raised further upward.

[0066] In this way, there has been no conventional structure that allows the thighs 7 to bend in the middle and improves the flexibility of the legs 6. By using the multi-stage swing from the first swing to the fourth swing, it is possible to make the doll body 2 pose with its thighs raised high.

[0067] 14, if the lower leg 8 is further swung backward and downward relative to the thigh 7 about the fifth swing shaft 77, the leg 6 can be brought into a state in which the knee is bent, as shown in Fig. 15. In the leg 6 of the doll body 2, the fifth swing shaft 77, which corresponds to the knee joint, is set at a position rearward of the front-to-back center line of the leg 6, so that the knee can be bent more greatly than in a configuration in which the fifth swing shaft 77 is set on the front-to-back center line.

[0068] By bending the knees, the user can make the doll body 2 assume, for example, a knee-kicking pose. When the knees are bent, the lower end of the thigh 7 and the upper end of the lower leg 8 move apart, causing the kneecaps to open, but the kneecap interior part 11 is positioned there, so the appearance can be maintained.

[0069] Furthermore, by rotating the lower leg part 82 relative to the upper leg part 81 about the lower leg rotation axis 87, the user can make the doll body 2 assume a pose in which the foot 9 is twisted inward or outward.

[0070] Next, the detailed structure of the foot portion 9 will be described. Figure 16 is a side view of the foot 9 and its surroundings. Figure 17 is an exploded view of the same. The foot 9 has a heel 91, a central portion 92 corresponding to the position of the arch of the foot, a connecting part 93 that connects the central portion 92 to the heel 91 so that the central portion 92 can be pulled out and swing up and down, a toe 94 that is connected to the central portion 92 so that the central portion 92 can swing up and down, and an instep cover 95.

[0071] The heel portion 91 is composed of two pieces, a bilaterally symmetrical right part 911 and a left part 912. The right part 911 and the left part 912 each have an annular sixth rocking bearing 913 provided at the front upper end, and a guide portion 914 provided in the internal space.

[0072] The two sixth oscillating bearings 913 on the left and right are fitted to sandwich the sixth oscillating shaft 181 protruding on the left and right sides of the foot joint 180 provided at the lower end of the lower leg part 82, connecting the foot 9 to the lower leg 8 so that it can oscillate in the front-to-back direction.

[0073] The guide part 914 has a groove structure into which the seventh swing shaft 931 protruding from the left and right side surfaces of the rear end of the connecting part 93 is slidably fitted, and forms an arc with the rear pointing slightly upward in a side view. When the right part 911 and the left part 912 are assembled so as to sandwich the connecting part 93 from the left and right, the seventh swing shaft 931 is sandwiched and held between the left and right guide parts 914, and the connecting part 93 is connected to the heel part 91 so as to be slidable back and forth and swingable up and down.

[0074] An eighth swing shaft 932 is provided to protrude from the left and right side surfaces of the front end of the connecting part 93, and is connected to the central part 92 by the protrusions so as to be swingable in the up and down direction.

[0075] The central portion 92 is composed of two pieces, an upper part 921 and a lower part 922, and is assembled by placing the upper part 921 over the lower part 922 so that the connecting part 93 is sandwiched between them from above and below. Inside the central portion 92, by assembling the upper part 921 over the lower part 922, an eighth swing bearing 923 that rotatably holds an eighth swing shaft 932 of the connecting part 93 and a ninth swing bearing 924 that rotatably holds a ninth swing shaft 941 protruding from both the left and right ends of the rear end extension portion of the toe portion 94 are formed.

[0076] The upper part 921 has a protruding ball portion 925. An instep cover 95 is connected to the upper surface of the ball portion 925 by a ball joint.

[0077] The instep cover 95 has an upper cover 952 having a socket portion 951 that connects to the ball portion 925, and a lower cover 953 that is connected to the toe side of the cover so as to be able to swing up and down.

[0078] Next, the operation of the foot 9 will be described. 18 to 20 are transition diagrams for explaining the operation of bending the foot 9, and the transitions are shown in the order of the figure numbers. Note that in these diagrams, some components are omitted and some parts are drawn in perspective to make it easier to understand.

[0079] As shown in Figure 18, when the doll body 2 is in an upright position, the heel 91, the middle 92, and the toe 94 are in close contact with each other in the front-to-rear direction. Focusing on the connecting part 93, the seventh swing shaft 931 is located at the rear end of the guide part 914. In this state, the sole of the foot 9 is flat and not curved.

[0080] From here, when the leg 6 is swung backward and the toe portion 94 is swung upward relative to the central portion 92 on the ninth swing axis 941, the foot 9 comes into a state in which the base of the toes touches the ground and the arch to the heel are raised, as shown in Figure 19.

[0081] From this point on, if the leg 6 is further swung backward, the center portion 92 is moved away from the heel portion 91, and the center portion 92 is swung relatively upward, the sole of the foot 9 will be arched as shown in Figure 20. At this time, if we focus on the connecting part 93, the seventh oscillation shaft 931 is located at the front end position of the guide part 914. The limit to this arching of the foot 9 is reached when the rear end of the upper part of the instep cover 95 comes into contact with the front lower end of the lower crus part 82.

[0082] In this way, the feet 9 of the doll body 2 can bend in the same way as human feet, so it is possible to make the doll body 2 assume a pose that realistically reproduces the feeling of pushing off the ground.

[0083] As described above, according to this embodiment, the flexibility of the lower body of the doll body 2 is improved, and various poses that were not possible with the prior art can be realized.

[0084] [Modification] The embodiments to which the present invention can be applied are not limited to the above examples, and constituent elements can be added, omitted, or modified as appropriate.

[0085] (Variation 1) In the above embodiment, an example of a configuration is shown in which the left and right first swing links 110 are connected together via the link support portion 104, but the left and right first swing links 110 may not be connected together, but may be connected to the link support portion 104 separately.

[0086] Specifically, the first groove 106 and the second groove 107 are not holes that pass through the link support part 104 from side to side, but are literally grooves recessed into the left and right side surfaces, respectively. Then, protrusions that engage with the grooves are provided on the left and right first swing links 110, respectively, instead of the left and right connecting protrusions 113 and the left and right connecting holes 114. Then, the left and right first swing links 110 may be assembled so as to be connected so as to swing along the left and right surfaces of the link support part 104, respectively.

[0087] (Variation 2) In the above embodiment, the connecting structure between the upper crus part 81 and the lower crus part 82 makes it possible to realize a state in which the lower crus part 8 of the leg 6 is twisted left and right. A similar connecting structure can also be applied to the configuration of the forearm part of the arm 5.

[0088] Specifically, FIG. 21 is a side view showing a configuration example in which the connecting structure between upper lower leg part 81 and lower lower leg part 82 in the above embodiment is applied to the left arm 5 of the doll body 2.

[0089] In this configuration, the arm 5 has an upper arm 51 and a forearm 53 connected to the upper arm 51 by an elbow joint 52 so as to be swingable (rotatable). The forearm 53 has an upper arm part 54 and a hand part 55.

[0090] Upper arm part 54 has inclined surface 541 whose normal faces diagonally downward and rearward, and has forearm rotation shaft 542 protruding from there in the same direction. The tip of forearm rotation shaft 542 has an expanded diameter portion.

[0091] Hand-side part 55 is composed of two pieces, right part 551 and left part 552, which are assembled facing each other to rotatably hold forearm rotation shaft 542 and hand joint 56. Specifically, hand-side part 55 has inclined surface 553 whose normal faces obliquely upward and forward, and has forearm rotation bearing 554 into which forearm rotation shaft 542, which penetrates into the internal space along the same direction, is rotatably fitted.

[0092] In other words, the connecting surface between the upper arm side part 54 and the hand side part 55 (the boundary surface between the inclined surface 541 and the inclined surface 553) forms a front-to-rear inclined surface that is inclined in the front-to-rear direction from the upper arm side on the rear side of the body of the doll body 2 toward the hand side on the front side of the body, and the hand side part 55 is connected to the upper arm side part 54 so as to be able to rotate along the front-to-rear inclined surface. Therefore, similar to the relative twisting between the upper leg part 81 and the lower leg part 82 in the lower leg part 8 in the above embodiment, it is possible to realize a relative twisting between the upper arm side part 54 and the hand side part 55 in the forearm part 53.

[0093] (Variation 3) Furthermore, although the doll body 2 has been given as an example of a movable toy, the movable toy to which the joint structure 100 of the present invention can be applied is not limited to human figures, and can be similarly applied to the joints of animals (whether real or fictional). In this case, although the joint structure 100 is used as a hip joint in the above embodiment, the joint structure 100 may be used as a neck joint in the case of a two-headed character.
