Description

[Technical field]

[0001] The present invention relates to model toys and model parts. [Background technology]

[0002] Model toys (doll bodies) of people and animals are required to realize natural movements and a variety of poses. Therefore, in order to realize movements and poses similar to those of humans and animals, various joints and rotating parts with a wider range of motion are realized in the doll body by using multiple parts. For example, in order to realize a forward bending movement, the abdomen, etc. can be divided into multiple parts and combined to realize a more natural forward bending movement with a wider range of motion by the movement of each part. Patent Document 1 proposes an abdominal joint structure for a doll in which a stomach member, a chest member, and a waist member are configured to be slidable around the support shaft of a connecting member.

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 1-138492 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, the chest member and the waist member are connected to a connecting member located inside the spherically shaped abdominal member, and the chest member is configured to be slidable around the abdominal member. By forming the abdominal member into a spherical shape, it is possible to prevent the lower part of the chest member from coming into contact with the abdominal member when the chest member is slid, thereby preventing the range of motion from being narrowed.

[0005] However, in the above-mentioned conventional configuration, the abdomen is formed into a spherical shape, which makes it difficult to give a natural impression to the external appearance of the doll body, resulting in an unnatural feeling. Also, the chest member slides around the abdomen member, which means that the abdomen member and the chest member move in a bending motion, making it difficult to give the impression of a natural forward bending motion.

[0006] The present invention provides, for example, a novel mechanism for a rotation mechanism in a model toy. [Means for solving the problem]

[0007] The present invention is, for example, a model toy comprising a first part having a pivot axis, and a second part having a rail portion that receives the pivot axis of the first part and is inserted into the first part so as to be rotatable around the pivot axis, and the second part is insertable into the first part and slidable within the range in which the rail portion is formed. The present invention also provides, for example, a model toy comprising a first part having a rotation axis, a second part having a rail portion that receives the rotation axis of the first part and is inserted into the first part so as to be rotatable around the rotation axis, a third part having a first connecting portion at one end and a second connecting portion at the other end, and a fourth part having one end that is rotatably connected to the first connecting portion and the other end that is connected to another part, the second part having a receiving portion that rotatably receives the second connecting portion of the third part and is insertable into the first part and slidable within the range in which the rail portion is formed, the first part and the second part are parts that form the abdomen of the model toy, and the third part and the fourth part form a joint between the chest and abdomen of the model toy.

[0008] The present invention is also characterized in that, for example, a model component includes a first part having a rotation axis, and a second part having a rail portion that receives the rotation axis of the first part and is inserted into the first part so as to be rotatable around the rotation axis, and the second part is insertable into the first part and slidable within the range in which the rail portion is formed. The present invention also provides, for example, a model part for a model toy, comprising: a first part having a rotation axis; a second part having a rail portion that receives the rotation axis of the first part and is inserted into the first part so as to be rotatable around the rotation axis; a third part having a first connecting portion at one end and a second connecting portion at the other end; and a fourth part having one end that is rotatably connected to the first connecting portion and the other end that is connected to another part, wherein the second part has a receiving portion that rotatably receives the second connecting portion of the third part and is insertable into the first part and slidable within the range in which the rail portion is formed, the first part and the second part are parts that form the abdomen of the model toy, and the third part and the fourth part form a joint between the chest and the abdomen of the model toy.

[0011] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0012] <Appearance of the model toy> First, an example of the external configuration of a model toy 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 shows the external front view of the model toy 100. Note that the x, y, and z arrows indicate the upward, left, and forward directions of the model toy, respectively, and the same is true for other drawings.

[0013] The model toy 100 includes a head 101 constituting a main body, an upper body 102 indicated by a dotted line area, arms 103a, 103b, a waist 104, and legs 105a, 105b. In this embodiment, a humanoid robot is used as an example of a model toy, but this is not intended to limit the present invention, and the present invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and ornaments.

[0014] The head 101 is rotatably connected to an upper body 102. A right arm 103b and a left arm 103a are further connected to the sides of the upper body 102 by connecting members, and a waist 104 is connected to the lower part of the upper body 102. The waist 104 includes hip joints, and a right leg 105b and a left leg 105a are each rotatably connected thereto.

[0015] <Upper body structure> The configuration of the upper body 102 of the model toy 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2(a) shows the front appearance of the model toy 100. Fig. 2(b) shows an exploded perspective view of the upper body 102. Fig. 2(a) is the same as Fig. 1, so the description will be omitted.

[0016] As shown in Fig. 2(b), the upper body 102 is configured to include parts 201 to 211b. The part 201 corresponds to the first part, has a hollow portion inside, and forms the lower part of the abdomen of the model toy 100. The parts 202 and 203 are assembled to each other to form the second part, and form the upper part of the abdomen of the model toy 100. The parts 202 and 203 are connected to the part 201 so as to be slidable and rotatable. The detailed configurations of the parts 201 to 203 will be described later.

[0017] Parts 204 and 205 correspond to the third and fourth parts, respectively, and are rotatably connected to each other. A connecting portion (second connecting portion) formed at the lower portion of part 204 is formed in a spherical shape, and is rotatably connected to parts 202 and 203. Parts 204 and 205 form a joint between the chest and abdomen of model toy 100. Part 205 is further rotatably connected to part 208 that forms the back of model toy 100. Part 208 corresponds to another part. Part 209 is further rotatably connected to part 208 above the portion to which part 205 is attached. Part 209 forms the neck of model toy 100, and part 210 that constitutes a neck joint is rotatably connected to part 209.

[0018] Part 206 is connected to a cylindrical portion formed on the front of model toy part 204, and forms part of the chest of model toy 100. Part 207 is connected to part 208 from the front of model toy 100 so as to sandwich parts 202 to 205. Part 207 is a part that forms part of the chest of model toy 100. Parts 211a and 211b are rotatably connected to both ends of part 207. Parts 211a and 211b each form a shoulder joint, and arms 103a and 103b are rotatably connected to them.

[0019] <Abdominal structure> The configuration of the abdomen of the model toy 100 according to this embodiment will be described with reference to Figures 3 and 4. Figure 3 shows the configuration of each of the parts 201 to 203. Figure 4 shows a plan view of the parts 201 to 204.

[0020] 3, part 201 is formed to include cylindrical rotating shafts 311a, 311b, a hollow portion 312, and a cylindrical through-hole 313. Cylindrical through-hole 313 is formed in the center of the interior of part 201, and some parts of waist portion 104 are rotatably connected to the through-hole from below model toy 100. Rotating shafts 311a, 311b are formed to extend outward from the outer circumferential wall of through-hole 313 in different directions.

[0021] The part 202 is formed to include a rail portion 321 and connection portions 322a and 322b. The rail portion 321 receives the rotation shaft 311a in a slidable manner. The connection portions 322a and 322b are fitting portions for connecting to the part 203.

[0022] Part 203 is formed to include rail portion 331, connecting portions 332a and 332b, and receiving portion 333. Rail portion 331 slidably receives rotation shaft 311b. Connecting portions 332a and 332b fit with connecting portions 322a and 322 of part 202, respectively. Receiving portion 333 is rotatably connected to second connecting portion 322 of part 204. Second connecting portion 322 of part 204 is formed in a spherical shape, and receiving portion 333 is formed so that its side cross section is U-shaped so as to be able to receive second connecting portion.

[0023] The parts 202 and 203 are connected via the connecting parts 322a, 322b, 332a, and 332b, and then the connected parts 202 and 203 are inserted into the hollow part 312 of the part 201. When the parts 202 and 203 constituting the second part are assembled, the rail parts 321 and 331 are formed on both sides of the inner wall of the second part. When the parts 202 and 203 are inserted into the part 201, the rotation shafts 311a and 311b are inserted into the rail parts 321 and 331, respectively. The rail parts 321 and 331 are not formed linearly in the vertical direction of the model toy 100, but are formed curved in an arch shape. In other words, the rail parts 321 and 331 are formed from the front of the lower abdomen toward the back at chest height. By forming them in this way, when the parts 201 and 202, 203 are slid within the range in which the rail portions 321, 331 are formed, and the parts 201 and 202, 203 are separated from each other, a larger gap can be formed in front of the abdomen. By utilizing this gap, the model toy 100 can be made to bend forward, and the effect of widening the range of motion in the forward bending motion can be obtained.

[0024] 4 shows a plan view of parts 201 to 203 with only part 202 removed. That is, it shows a state in which parts 201 and 203 are assembled. Normally, parts 202 and 203 are inserted into part 201 in an assembled state, but here, in order to easily explain the positional configuration of receiving portion 333 of part 203, part 202 is shown removed.

[0025] Receiving portion 333 of part 203 is located above through-hole 313 of part 201 when part 203 is inserted into part 201. That is, receiving portion 333 is disposed near the center of part 201. Also, receiving portion 333 is formed with a predetermined width. This allows it to rotatably receive the second connecting portion of part 204 from above.

[0026] <Sliding movement of abdomen> The sliding movement of the abdomen of the model toy 100 according to this embodiment will be described with reference to Fig. 5. Fig. 5(a) shows a side view of the upper body part 102 of the model toy 100. Figs. 5(b) to 5(d) show cross-sectional side views of the upper body part 102 of the model toy 100.

[0027] 5(a) and 5(b) show a side view and a cross-sectional side view in the case where each part is located at the same position. As shown in FIG. 5(b), part 203 (part 202) can slide in the direction of arrow x1 relative to part 201 by rail portion 331 (rail portion 321). Also, part 201 and part 203 (part 202) can rotate in the direction of arrow x2 around rotation axis 311b (311a).

[0028] 5(c) shows a first state in which the rotating shaft 311b (311a) has been slid to the back of the rail portion 331 (rail portion 321). In the first state, it can be seen that the part 201, which is the first part, and the part 203 (part 202), which is the second part, are tightly connected to each other.

[0029] FIG. 5(d) shows a state where the part 203 (part 202) is slid in the direction of the arrow x3 from the first state in FIG. 5(c). A second state is shown where the rotation shaft 311b (311a) is slid to the vicinity of the tip end on the opposite side to the inner part of the rail part 331 (rail part 321). In the model toy 100 according to this embodiment, the degree to which the parts 202 and 203 are inserted into the part 201 can be adjusted between the first state and the second state. The diameter of the rotation shaft 311b (311a) is formed to be shorter than the width of the rail part 331 (rail part 321), but by making these lengths as close as possible, the holding force of the rotation shaft 311b (311a) by the rail part 331 (rail part 321) can be increased, and the rotation shaft 311b (311a) can be slid and held at a desired position. In other words, the state can be adjusted to other states without being limited to the first state and the second state. This allows an appropriate gap to be formed to realize a desired rotation. In the second state, a gap is formed between the first part, part 201, and the second part, part 203 (part 202), as indicated by the dotted arrow L1. Using this gap, part 201 is rotated upward about rotation axis 311b (311a) as indicated by arrow x2, or part 203 (202) is rotated downward, resulting in a forward bending motion state as shown in Figures 5(a) and 5(b). Note that in the model toy 100 according to this embodiment, there are multiple mechanisms for providing gaps between parts for such forward bending motion. Other mechanisms for providing gaps will be described later.

[0030] <Side section of upper body> A rotation mechanism for assisting the forward bending motion of the model toy 100 according to this embodiment will be described with reference to Fig. 6. Fig. 6 shows a side cross-sectional view of the upper body portion 102.

[0031] Part 601 is connected to the upper part of waist 104. Part 610 has a spherical connecting part 611 at its upper part. Connecting part 611 is rotatably inserted from the lower part of through hole 313 of part 201. Also, as described above, parts 202 and 203 can rotate around rotation axis 311b (311a).

[0032] Furthermore, in the rotation mechanism of the model toy 100, the second connecting portion 602 of the part 204 is rotatably connected to the receiving portion 333 of the part 203. As shown in the dotted line frame, the part 204 has a first connecting portion 601 at one end and a second connecting portion 602 at the other end. Furthermore, the first connecting portion 601 of the part 204 is rotatably connected to the connecting portion 603 of the part 205. The part 205 has connecting portions 603 and 604. The connecting portion 603 is rotatably connected to the part 208 corresponding to the other part. The parts 204 and 205 can rotate as shown in the dotted line frame, and the state before the rotation corresponds to the third state, and the state in the dotted line frame after the rotation corresponds to the fourth state. In the fourth state, the connected part 208 is lifted in the direction of the arrow x4, and the part 207 and the like connected to the part 208 are also lifted accordingly. As a result, a gap is formed between the parts 202 and 203, which are the second part, and the part 208, which is the other part.

[0033] Part 210 is a part that constitutes a neck joint that connects head 101 and chest 102. Part 210 has connecting parts at the top and bottom, which are rotatably connected to some parts of head 101 and part 209, respectively. Furthermore, part 210 is formed so that the center of the part can rotate and bend.

[0034] In this way, the model toy 100 includes multiple rotation mechanisms that support forward bending motion. As described above, the multiple rotation mechanisms include at least the rotation mechanisms at the locations of the curved arrows in FIG. 6. In addition, the model toy 100 has multiple mechanisms that slide upward, and gaps are provided between each part to ensure space for rotational motion. This allows the range of motion to be expanded.

[0035] <Upper body movements> The movement (forward bending movement) of the upper body 102 according to this embodiment will be described with reference to Fig. 7. Fig. 7(a) and Fig. 7(b) show side cross-sectional views of the model toy 100.

[0036] FIG. 7(a) shows the state where each part is slid upward. Specifically, the above-mentioned related parts slide in the directions of the arrows x3, x4, and x5. Arrow x5 shows the state where the head 101 is slid relative to the part 210. This is achieved by forming the connecting part of the part 210 slidably in the recess of the head 101 into which the connecting part is inserted. These slides ensure gaps L1, L2, and L3 between each part. These ensured gaps can be used to perform rotational movements, and restrictions on the range of motion due to interference between parts can be alleviated.

[0037] FIG. 7(b) shows the model toy 100 bending forward. As shown by the curved arrows, each rotation mechanism rotates to achieve a more natural rotation and a larger range of motion. In addition to providing gaps to reduce interference between parts, a mechanism may be provided that allows one part to move into the other part. For example, as shown in FIG. 7(b), part 202 can move into part 207.

[0038] As described above, the model toy according to this embodiment includes a first part (201) having a rotation axis, and a second part (202, 203) having a rail portion that receives the rotation axis of the first part and is inserted into the first part so as to be rotatable about the rotation axis, and the second part can be inserted into the first part and slid within the range of the rail portion. In this way, according to this embodiment, a novel mechanism for a rotation mechanism in a model toy can be provided.

[0039] <Modification> The present invention is not limited to the above-mentioned embodiment, and various modifications and changes are possible within the scope of the gist of the invention. For example, the shape of the model toy is not particularly limited, and includes various shapes such as humans, animals, robots, insects, and dinosaurs. In addition, in the above-mentioned embodiment, the sliding mechanism and the rotating mechanism of the parts 201 to 203 are described as being adopted in the abdomen (waist joint). However, this is not intended to limit the present invention, and these mechanisms may be used in other parts. For example, they may be applied to the chest joint or the neck joint.
