Description

Technical Field

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

Background Art

[0002] In model toys (humanoid figures) such as humans and animals, it is required to realize natural movements and various 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 movement are realized by a plurality of parts in the humanoid figure. For example, in order to realize a forward bending motion, the abdomen etc. is divided into a plurality of parts and combined, and by the movement of each part, a more natural and wider-range forward bending motion can be realized. Patent Document 1 proposes an abdominal joint structure of a human figure in which an abdominal member, a chest member, and a waist member are configured to be slidable around a support shaft of a connecting member.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, the chest member and the waist member are connected to a connecting member located inside the spherical 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 contacting the abdominal member when the chest member is slid, thereby preventing the range of movement from narrowing.

[0005] However, with the configuration of the conventional technology described above, the abdomen is formed in a spherical shape, making it difficult to give a natural impression to the appearance of the doll body, resulting in an unnatural look. Furthermore, the chest member slides around the abdominal member, meaning that the space between the abdominal and chest members bends, 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 rotating mechanism in a model toy. [Means for solving the problem]

[0007] The present invention relates to, for example, a model toy comprising a first part having a pivot axis and a second part having a rail portion for receiving the pivot axis of the first part, and being rotatably inserted into the first part around the pivot axis, wherein the second part is slidable into the first part within the range in which the rail portion is formed.

[0008] Furthermore, the present invention relates to, for example, a model part comprising a first part having a pivot axis and a second part having a rail portion for receiving the pivot axis of the first part, and being rotatably inserted into the first part about the pivot axis, wherein the second part is slidable into the first part within the range in which the rail portion is formed. [Effects of the Invention]

[0009] According to the present invention, a novel mechanism for rotation in model toys can be provided. [Brief explanation of the drawing]

[0011] The embodiments will be described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention as defined in the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more of the features described in the embodiments may be combined arbitrarily. Furthermore, identical or similar configurations will be given the same reference numeral, and redundant descriptions will be omitted.

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

[0013] The model toy 100 comprises a head 101, an upper body 102 (shown by the dotted line area), arms 103a and 103b, a waist 104, and legs 105a and 105b, which constitute the main body. In this embodiment, a humanoid robot is used as an example of a model toy, but there is no intention to limit the present invention, and the present invention can be applied to various models such as people, animals, robots, insects, dinosaurs, weapons, ornaments, etc.

[0014] The head 101 is rotatably connected to the upper body 102. The right arm 103b and the left arm 103a are further connected to the upper body 102 at the sides by connecting members, and the waist 104 is connected at the bottom. The waist 104 includes a hip joint, to which the right leg 105b and the left leg 105a are rotatably connected.

[0015] <Configuration of the upper body part> Referring to FIG. 2, the configuration of the upper body part 102 of the model toy 100 according to the present embodiment will be described. FIG. 2(a) shows the front appearance of the model toy 100. FIG. 2(b) shows an exploded perspective view of the upper body part 102. Since FIG. 2(a) is the same drawing as FIG. 1, the description thereof will be omitted.

[0016] As shown in FIG. 2(b), the upper body part 102 is configured to include parts 201 to 211b. The part 201 corresponds to the first part, has a cavity inside, and forms the lower part of the abdomen of the model toy 100. The parts 202 and 203 are assembled with 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 slidably and rotatably. The detailed configuration of the parts 201 to 203 will be described later.

[0017] The parts 204 and 205 correspond to the third part and the fourth part respectively, and are rotatably connected to each other. The connecting part (the second connecting part) formed at the lower part of the part 204 is formed in a spherical shape and is rotatably connected to the parts 202 and 203. The parts 204 and 205 form a joint between the chest and the abdomen of the model toy 100. The part 205 is further rotatably connected to the part 208 that forms the back of the model toy 100. The part 208 corresponds to other parts. Further, a part 209 is rotatably connected to the upper side of the part where the part 205 is assembled on the part 208. The part 209 forms the neck of the model toy 100, and a part 210 that constitutes the neck joint is rotatably connected thereto.

[0018] Part 206 is connected to the cylindrical portion formed on the front surface of the model toy part 204, and forms a part of the chest of the model toy 100. Part 207 is connected from the front direction of the model toy 100 so as to sandwich part 208 and parts 202 - 205. Part 207 is a part that forms a part of the chest of the model toy 100. Parts 211a and 211b are respectively rotatably connected to both ends of part 207. Parts 2011a and 211b respectively form shoulder joints, and the arm portions 103a and 103b are respectively rotatably connected thereto.

[0019] <Configuration of the abdomen> Referring to FIGS. 3 and 4, the configuration of the abdomen of the model toy 100 according to the present embodiment will be described. FIG. 3 shows the configurations of parts 201 - 203 respectively. FIG. 4 shows a plan view of parts 201 - 204.

[0020] As shown in FIG. 3, part 201 is formed including cylindrical rotation shafts 311a and 311b, a cavity 312, and a cylindrical through - hole 313. A cylindrical through - hole 313 is formed at the center inside part 201, and a part of the waist 104 is rotatably connected to the through - hole from the lower direction of the model toy 100. The rotation shafts 311a and 311b are formed so as to extend in different directions outward from the outer peripheral wall of the through - hole 313.

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

[0022] Part 203 is formed including a rail section 331, connecting sections 332a and 332b, and a receiving section 333. The rail section 331 slidably receives the pivot shaft 311b. The connecting sections 332a and 332b fit with the connecting sections 322a and 322 of part 202, respectively. The receiving section 333 is rotatably connected to the second connecting section of part 204. The second connecting section of part 204 is formed in a spherical shape, and the receiving section 333 is formed with a U-shaped side cross-section to accommodate the second connecting section.

[0023] Parts 202 and 203 are connected via connecting parts 322a, 322b, 332a, and 332b, after which the connected parts 202 and 203 are inserted into the cavity 312 of part 201. When parts 202 and 203, which constitute the second part, are assembled, rail sections 321 and 331 are formed on both sides of the inner wall of the second part. When inserting parts 202 and 203 into part 201, pivot shafts 311a and 311b are inserted into the rail sections 321 and 331, respectively. Note that the rail sections 321 and 331 are not formed in a straight line in the vertical direction of the model toy 100, but are formed in a curved, bow-shaped form. In other words, the rail sections 321 and 331 are formed from the front of the lower abdomen toward the back at chest height. By forming it in this way, when part 201 and parts 202 and 203 are slid within the formed range of rail sections 321 and 331, and part 201 and parts 202 and 203 are separated, a larger gap can be formed in front of the abdomen. This gap can be used to enable the model toy 100 to bend forward, and the range of motion in the bending motion can be increased.

[0024] Figure 4 shows a plan view of parts 201 to 203, with only part 202 removed. In other words, it shows the assembled state of parts 201 and 203. Normally, parts 202 and 203 are assembled and then inserted into part 201, but here, part 202 is removed to easily explain the positional configuration of the receiving portion 333 of part 203.

[0025] The receiving portion 333 of part 203 is located above the through hole 313 of part 201 when part 203 is inserted into part 201. That is, the receiving portion 333 is positioned near the center on part 201. The receiving portion 333 is also formed with a predetermined width. This allows the second connecting portion of part 204 to be rotatably received from above.

[0026] <Sliding movement of the abdomen> Referring to Figure 5, the sliding movement of the abdomen in the model toy 100 according to this embodiment will be explained. Figure 5(a) shows a side view of the upper body portion 102 of the model toy 100. Figures 5(b) to 5(d) show side cross-sectional views of the upper body portion 102 of the model toy 100.

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

[0028] Figure 5(c) shows the first state in which the pivot shaft 311b (311a) is slid all the way to the back of the rail section 331 (rail section 321). In the first state, it can be seen that the first part, part 201, and the second part, part 203 (part 202), are tightly connected.

[0029] Figure 5(d) shows the state in which part 203 (part 202) has been slid in the direction of arrow x3 from the first state in Figure 5(c). The second state shows the pivot shaft 311b (311a) slid near the tip opposite the inner end of the rail section 331 (rail section 321). In the model toy 100 according to this embodiment, the degree to which parts 202 and 203 are inserted into part 201 can be adjusted between the first and second states. The diameter of the pivot shaft 311b (311a) is formed to be shorter than the width of the rail section 331 (rail section 321), but by bringing their lengths as close as possible, the holding force of the pivot shaft 311b (311a) by the rail section 331 (rail section 321) can be increased, allowing it to slide and hold in the desired position. In other words, it can be adjusted to other states, not just the two states of the first and second states. This allows for the formation of an appropriate gap to achieve the 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 shown by the dotted arrow L1. By using this gap to rotate part 201 upward around the pivot axis 311b (311a), or to rotate part 203 (202) downward, as shown by arrow x2, the forward bending motion shown in Figures 5(a) and 5(b) is achieved. In the toy model 100 according to this embodiment, there are multiple mechanisms for creating gaps between parts to enable such forward bending motion. Other mechanisms for creating gaps will be described later.

[0030] <Side cross-section of the upper body> Referring to Figure 6, the rotation mechanism that assists the forward bending motion of the model toy 100 according to this embodiment will be described. Figure 6 shows a side cross-sectional view of the upper body portion 102.

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

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

[0033] Part 210 is a component that forms the neck joint connecting the head 101 and the chest 102. Part 210 has connecting parts on its upper and lower ends, and is rotatably connected to a part of the head 101 and to part 209, respectively. Furthermore, part 210 is formed so that its central part can bend and rotate.

[0034] Thus, this toy model 100 includes multiple rotational mechanisms to support forward bending. As mentioned above, these multiple rotational mechanisms include at least the rotational mechanisms indicated by the curved arrows in Figure 6. It also has multiple mechanisms that slide upward, allowing for gaps between parts and securing space for rotational movement. This expands the range of motion.

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

[0036] Figure 7(a) shows each part being slid upward. Specifically, the related parts described above slide in the directions of arrows x3, x4, and x5. Arrow x5 shows the head 101 sliding relative to part 210. This is achieved by forming the connecting part of part 210 into a recess in the head 101 into which the connecting part is inserted, so that the connecting part is slidable. These slides secure gaps L1, L2, and L3 between each part. By using these secured gaps, rotational movement can be performed, mitigating limitations on the range of motion due to interference between parts.

[0037] Figure 7(b) shows the model toy 100 performing a forward bending motion. As indicated by the multiple curved arrows, each rotation mechanism performs a rotational motion, resulting in a more natural rotation and a larger range of motion. In addition to ensuring gaps to reduce interference between parts, a mechanism may be provided that allows one part to fit into another. For example, as shown in Figure 7(b), part 202 can be made to fit inside part 207.

[0038] As described above, the model toy according to this embodiment comprises a first part (201) having a pivot axis, and second parts (202, 203) having a rail portion for receiving the pivot axis of the first part, and being rotatably inserted into the first part around the pivot axis, with the second parts being slidable into the first part within the range of the rail portion. Thus, according to this embodiment, a novel mechanism for a rotating mechanism in a model toy can be provided.

[0039] <Variation> The present invention is not limited to the embodiments described above, 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 people, animals, robots, insects, dinosaurs, etc. Furthermore, in the above embodiments, a form was described in which the sliding mechanism and rotation mechanism of parts 201 to 203 are used in the abdomen (waist joint). However, there is no intention 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 neck joint.
