[0029] <Appearance of the model toy>

[0030] A configuration example of a model toy 100 according to an embodiment of the present invention will be described. Figure 1 1 is a diagram showing an example of the external appearance structure of the model toy 100 according to the present embodiment. Figure 1 (a) shows the front appearance of the model toy 100. Figure 1 (b) shows the outer side of the model toy 100. In addition, the arrows of x, y, and z respectively indicate the directions of the left, upper, and front directions in the model toy 100, and the same applies to the other drawings.

[0031] The model toy 100 includes a head 101, a chest 102, arms 103a-103b, legs 104a-104b, and a waist 105 constituting a main body. In the present embodiment, a humanoid robot is used as an example of the model toy 100, but the present invention is not intended to be limited thereto, and the present invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and ornaments.

[0032] The head 101 is connected to the chest 102. The right arm 103b and the left arm 103a are also connected to the chest 102 at the side, and the waist 105 is connected to the lower part. The waist 105 includes a hip joint and is rotatably connected to the right leg 104b and the left leg 104a. In addition, as shown in the dotted rectangular area, the right arm 103b and the left arm 103a have a right hand component 106b and a left hand component 106a at the top end, respectively.

[0033] <Structure of the elbow joint>

[0034] like Figure 1As shown, the left arm portion 103a and the right arm portion 103b of the model toy 100 of the present embodiment are respectively provided with an elbow joint portion 107 configured in a manner that allows flexion and extension. The elbow joint portion 107 is a model component (movable component) composed of a plurality of accessories (components) connected to each other in a manner that allows rotation. For the elbow joint portion 107, in addition to expanding the movable area of ​​flexion and extension movements, it is also required to be easy to assemble and difficult for a plurality of accessories to be separated after assembly. Below, the elbow joint portion 107 of the left arm portion 103a is illustrated, the assembly of the elbow joint portion 107 is explained in sequence, and an example of its structure is shown.

[0035] The elbow joint 107 includes an elbow base member 10 (member) and a first elbow fitting 20 (first fitting) connected to each other. Figure 2A to Figure 2B , the connection between the elbow base member 10 and the first elbow fitting 20 will be described. Figure 2A The elbow base member 10 and the first elbow fitting 20 are shown in a state where they are separated. Figure 2B The state in which the elbow base member 10 and the first elbow fitting 20 are connected is shown.

[0036] The first elbow fitting 20 has a clamping portion 20a that clamps the upper portion 10a, which is one end portion of the elbow base member 10, and has a protrusion 22 (first protrusion) on the inner side surface 21 of the clamping portion 20a. The protrusion 22 engages with the groove 12 (first groove) provided on the outer side surface 11 of the upper portion 10a of the elbow base member 10, and becomes a rotation axis when the first elbow fitting 20 rotates relative to the elbow base member 10. In the present embodiment, the protrusions 22 are respectively provided on two inner side surfaces 21 facing each other in the clamping portion 20a of the first elbow fitting 20.

[0037] The groove 12 of the elbow base member 10 is provided on the outer side surface 11 of the upper portion 10a sandwiched by the clamping portion 20a of the first elbow fitting 20, and extends in one direction starting from the rotation axis when the first elbow fitting 20 rotates. That is, the outer side surface 11 of the elbow base member 10 is formed into a letter C shape by the groove 12 opened in one direction. In the present embodiment, the grooves 12 are respectively provided on two outer side surfaces 11 on opposite sides of the upper portion 10a of the elbow base member 10.

[0038] The connection between the elbow base member 10 and the first elbow fitting 20 is performed in a state where the elbow base member 10 and the first elbow fitting 20 are in a predetermined relative posture (first relative posture). Figure 2AAs shown, the predetermined relative posture of the elbow base member 10 and the first elbow fitting 20 refers to the relative posture of the elbow base member 10 and the first elbow fitting 20 when the angle α between the imaginary line La extending in the longitudinal direction of the elbow base member 10 and the imaginary line Lb extending in the longitudinal direction of the first elbow fitting 20 is a predetermined angle. The predetermined angle is a value less than 90 degrees (preferably less than 60 degrees, more preferably less than 45 degrees). In a state where the elbow base member 10 and the first elbow fitting 20 are in the predetermined relative posture, the first elbow fitting 20 is moved relative to the elbow base member 10 along the groove 12 of the elbow base member 10, so that the protrusion 22 of the first elbow fitting 20 is engaged with the groove 12.

[0039] After the protrusion 22 of the first elbow fitting 20 is engaged with the groove 12 of the elbow base member 10, Figure 2B As shown, the first elbow fitting 20 is rotated relative to the elbow base member 10 with the protrusion 22 as the rotation axis A1 (center). Thus, the first elbow fitting 20 is connected to the elbow base member 10. The first elbow fitting 20 is provided with a restraining portion 23 (restricting portion) for restraining (restricting) the movement of the first elbow fitting 20 along the groove 12 of the elbow base member 10 when the elbow base member 10 and the first elbow fitting 20 connected to each other are in a posture different from the prescribed relative posture (first relative posture). The restraining portion 23 restrains the movement of the first elbow fitting 20 along the groove 12 relative to the elbow base member 10 by contacting the elbow base member 10 when the elbow base member 10 and the first elbow fitting 20 connected to each other are in a posture different from the prescribed relative posture (first relative posture). Thus, it is possible to make it difficult for the first elbow fitting 20 to detach from the elbow base member 10.

[0040] In addition, the elbow joint portion 107 further includes a second elbow fitting 30 (second fitting) connected to the elbow base member 10. Figure 3A to Figure 3B , the connection between the elbow base member 10 and the second elbow fitting 30 will be described. Figure 3A The elbow base member 10 and the second elbow fitting 30 are shown in a state where they are separated. Figure 3B The state where the elbow base member 10 and the second elbow fitting 30 are connected is shown.

[0041] The second elbow fitting 30 has a clamping portion 30a that clamps the lower portion 10b, which is the other end portion of the elbow base member 10, and has a protrusion 32 (second protrusion) on the inner side surface 31 of the clamping portion 30a. The protrusion 32 engages with the groove 14 (second groove) provided on the outer side surface 13 of the lower portion 10b of the elbow base member 10, and serves as a rotation axis when the second elbow fitting 30 rotates relative to the elbow base member 10. In the present embodiment, the protrusions 32 are provided on two inner side surfaces 31 facing each other in the clamping portion 30a of the second elbow fitting 30.

[0042] The groove 14 of the elbow base member 10 is provided on the outer side surface 13 of the lower portion 10b sandwiched by the clamping portion 30a of the second elbow fitting 30, and extends in one direction starting from the rotation axis when the second elbow fitting 30 rotates. That is, the outer side surface 13 of the elbow base member 10 is formed into a letter C shape by the groove 14 open in one direction. In the present embodiment, the groove 14 is respectively provided on two outer side surfaces 13 on opposite sides of the lower portion 10b of the elbow base member 10.

[0043] The connection between the elbow base member 10 and the second elbow fitting 30 is performed in a state where the elbow base member 10 and the second elbow fitting 30 are in a predetermined relative posture (second relative posture). Figure 3A As shown, the predetermined relative posture of the elbow base member 10 and the second elbow fitting 30 refers to the relative posture of the elbow base member 10 and the second elbow fitting 30 when the angle β between the imaginary line La extending in the longitudinal direction of the elbow base member 10 and the imaginary line Lc extending in the longitudinal direction of the second elbow fitting 30 is a predetermined angle. The predetermined angle is a value less than 90 degrees (preferably less than 60 degrees, more preferably less than 45 degrees). In a state where the elbow base member 10 and the second elbow fitting 30 are in the predetermined relative posture, the second elbow fitting 30 is moved relative to the elbow base member 10 along the groove 14 of the elbow base member 10, so that the protrusion 32 of the second elbow fitting 30 is engaged with the groove 14.

[0044] After the protrusion 32 of the second elbow fitting 30 is engaged with the groove 14 of the elbow base member 10, Figure 3B As shown, the second elbow fitting 30 is rotated relative to the elbow base member 10 with the protrusion 32 as the rotation axis A2 (center). Thus, the second elbow fitting 30 is connected to the elbow base member 10. The second elbow fitting 30 is provided with a restraining portion 33 (restricting portion) for restraining (restricting) the movement of the second elbow fitting 30 along the groove 14 of the elbow base member 10 when the elbow base member 10 and the second elbow fitting 30 connected to each other are in a posture different from the predetermined relative posture (second relative posture). The restraining portion 33 restrains the movement of the second elbow fitting 30 along the groove 14 relative to the elbow base member 10 by contacting the elbow base member 10 when the elbow base member 10 and the second elbow fitting 30 connected to each other are in a posture different from the predetermined relative posture (second relative posture). Thus, it is possible to make it difficult for the second elbow fitting 30 to detach from the elbow base member 10.

[0045] Here, if Figure 2A As shown, in the elbow base member 10, the groove 12 of the upper part 10a and the groove 14 of the lower part 10b can be set to open toward the same side surface 15 (the surface on the +Z direction side). The extending direction of the groove 12 of the upper part 10a and the extending direction of the groove 14 of the lower part 10b can also be parallel. Figure 4As shown, various exterior components 41 to 47 are attached to the elbow joint 107 assembled as described above. This prevents the components of the elbow joint 107 from being separated, and the arm 103 (left arm 103a) of the model toy 100 is formed.

[0046] As described above, in the elbow joint portion 107 of the present embodiment, the elbow base member 10 and the first elbow fitting 20 are connected to each other by engaging the protrusion 22 of the first elbow fitting 20 with the groove 12 of the elbow base member 10 in a predetermined relative posture (first relative posture) and then rotating each other with the protrusion 22 as a rotation axis. In addition, the movement of the first elbow fitting 20 along the groove 12 of the elbow base member 10 is suppressed by the suppression portion 23 of the first elbow fitting 20 in a state different from the predetermined relative posture.

[0047] Similarly, the elbow base member 10 and the second elbow fitting 30 are connected to each other by engaging the protrusion 32 of the second elbow fitting 30 with the groove 14 of the elbow base member 10 in a predetermined relative posture (second relative posture) and then rotating each other with the protrusion 32 as a rotation axis. In addition, the movement of the second elbow fitting 30 along the groove 14 of the elbow base member 10 is suppressed by the suppression portion 33 of the second elbow fitting 30 in a state different from the second relative posture.

[0048] Through such a structure, in the elbow joint part 107 of this embodiment, in addition to expanding the movable area of ​​​​extension and flexion, it is also possible to make the multiple accessories (elbow base component 10, first elbow accessory 20, second elbow accessory 30) that constitute the elbow joint part 107 easy to assemble and make the multiple accessories difficult to detach after assembly.

[0049] <Structure of the knee joint>

[0050] like Figure 1 As shown, the left leg 104a and the right leg 104b of the model toy 100 of the present embodiment are respectively provided with a knee joint 108 that is configured in a manner that can be flexed and extended. The knee joint 108 is a model component (movable component) composed of a plurality of accessories (components) that are connected to each other in a manner that can rotate. For the knee joint 108, in addition to expanding the movable range of flexion and extension movements, it is also required to be easy to assemble and difficult to separate a plurality of accessories after assembly, similarly to the elbow joint 107. Below, the knee joint 108 of the left leg 104a is illustrated, and the assembly of the knee joint 108 is described in order, and its structural example is shown. In addition, the structure of the knee joint 108 is different from that of the above-mentioned elbow joint 107 in the number of accessories, but is basically the same structure. Therefore, below, sometimes the description and illustration of the structure identical to the structure of the above-mentioned elbow joint 107 are omitted.

[0051] The knee joint 108 includes a knee base member 50 (member) and a first knee attachment 60 (first attachment) connected to each other. Figure 5A to Figure 5B , the connection between the knee base member 50 and the first knee accessory 60 will be described. Figure 5A The knee base member 50 and the first knee attachment 60 are shown in a state where they are separated. Figure 5B The figure shows a state where the knee base member 50 is connected to the first knee fitting 60. The knee base member 50 and the first knee fitting 60 in the knee joint portion 108 correspond to the elbow base member 10 and the first elbow fitting 20 in the elbow joint portion 107, respectively.

[0052] The first knee fitting 60 has a clamping portion 60a that clamps the upper portion 50a, which is one end portion of the knee base member 50, and has a protrusion 62 (first protrusion) on the inner side surface 61 of the clamping portion 60a. The protrusion 62 engages with the groove 52 (first groove) provided on the outer side surface 51 of the upper portion 50a of the knee base member 50, and serves as a rotation axis when the first knee fitting 60 rotates relative to the knee base member 50. In the present embodiment, the protrusions 62 are provided on two inner side surfaces 61 that face each other in the clamping portion 60a of the first knee fitting 60.

[0053] The groove 52 of the knee base member 50 is provided on the outer side surface 51 of the upper portion 50a sandwiched by the clamping portion 60a of the first knee accessory 60, and extends in one direction starting from the rotation axis when the first knee accessory 60 rotates. That is, the outer side surface 51 of the knee base member 50 is formed in the shape of a letter C by the groove 52 opened in one direction. In the present embodiment, the grooves 52 are respectively provided on two outer side surfaces 51 on opposite sides of the upper portion 50a of the knee base member 50.

[0054] The knee base member 50 and the first knee accessory 60 are connected with each other in a state where the knee base member 50 and the first knee accessory 60 are in a predetermined relative posture (first relative posture). Figure 5A As shown, the predetermined relative posture of the knee base member 50 and the first knee accessory 60 refers to the relative posture of the knee base member 50 and the first knee accessory 60 when the angle γ between the imaginary line Ld extending in the longitudinal direction of the knee base member 50 and the imaginary line Le extending in the longitudinal direction of the first knee accessory 60 is a predetermined angle. The predetermined angle is a value less than 90 degrees (preferably less than 60 degrees, more preferably less than 45 degrees). In a state where the knee base member 50 and the first knee accessory 60 are in the predetermined relative posture, the first knee accessory 60 is moved relative to the knee base member 50 along the groove 52 of the knee base member 50, so that the protrusion 62 of the first knee accessory 60 is engaged with the groove 52.

[0055] After the protrusion 62 of the first knee fitting 60 is engaged with the groove 52 of the knee base member 50, Figure 5BAs shown in FIG. 1 , the first knee fitting 60 is rotated relative to the knee base member 50 with the protrusion 62 as the rotation axis A3 (center). Thus, the first knee fitting 60 is connected to the knee base member 50. The first knee fitting 60 is provided with a restraining portion 63 (restricting portion) for restraining (restricting) the movement of the first knee fitting 60 along the groove 52 of the knee base member 50 when the knee base member 50 and the first knee fitting 60 connected to each other are in a posture different from a predetermined relative posture (first relative posture). The restraining portion 63 restrains the movement of the first knee fitting 60 along the groove 52 relative to the knee base member 50 by contacting the knee base member 50 when the knee base member 50 and the first knee fitting 60 connected to each other are in a posture different from a predetermined relative posture (first relative posture). Thus, the first knee fitting 60 can be made difficult to be separated from the knee base member 50.

[0056] In addition, the knee joint portion 108 further includes a second knee fitting 70 (second fitting) connected to the knee base member 50. Figure 6A to Figure 6B , the connection between the knee base member 50 and the second knee accessory 70 will be described. Fig. 6A The knee base member 50 and the second knee attachment 70 are shown in a state where they are separated. Figure 6B The state where the knee base member 50 is connected to the second knee fitting 70 is shown. In addition, the second knee fitting 70 in the knee joint portion 108 corresponds to the second elbow fitting 30 in the elbow joint portion 107.

[0057] The second knee fitting 70 has a clamping portion 70a that clamps the lower portion 50b, which is the other end portion of the knee base member 50, and has a protrusion 72 (second protrusion) on the inner side surface 71 of the clamping portion 70a. The protrusion 72 engages with the groove 54 (second groove) provided on the outer side surface 53 of the lower portion 50b of the knee base member 50, and serves as a rotation axis when the second knee fitting 70 rotates relative to the knee base member 50. In the present embodiment, the protrusions 72 are provided on two inner side surfaces 71 that face each other in the clamping portion 70a of the second knee fitting 70.

[0058] The groove 54 of the knee base member 50 is provided on the outer side surface 53 of the lower portion 50b sandwiched by the clamping portion 70a of the second knee fitting 70, and extends in one direction starting from the rotation axis when the second knee fitting 70 rotates. That is, the outer side surface 53 of the knee base member 50 is formed in the shape of a letter C by the groove 54 opened in one direction. In the present embodiment, the groove 54 is respectively provided on two outer side surfaces 53 on opposite sides of the lower portion 50b of the knee base member 50.

[0059] The knee base member 50 and the second knee fitting 70 are connected with each other in a state where the knee base member 50 and the second knee fitting 70 are in a predetermined relative posture (second relative posture). Fig. 6AAs shown, the predetermined relative posture of the knee base member 50 and the second knee fitting 70 refers to the relative posture of the knee base member 50 and the second knee fitting 70 when the angle δ between the imaginary line Ld extending in the longitudinal direction of the knee base member 50 and the imaginary line Lf extending in the longitudinal direction of the second knee fitting 70 is a predetermined angle. The predetermined angle is a value less than 90 degrees (preferably less than 60 degrees, more preferably less than 45 degrees). In a state where the knee base member 50 and the second knee fitting 70 are in the predetermined relative posture, the second knee fitting 70 is moved relative to the knee base member 50 along the groove 54 of the knee base member 50, so that the protrusion 72 of the second knee fitting 70 is engaged with the groove 54.

[0060] After the protrusion 72 of the second knee fitting 70 is engaged with the groove 54 of the knee base member 50, Figure 6B As shown, the second knee fitting 70 is rotated relative to the knee base member 50 with the protrusion 72 as the rotation axis A4 (center). As a result, the second knee fitting 70 is connected to the knee base member 50. The second knee fitting 70 is provided with a restraining portion 73 (restricting portion) for restraining (restricting) the movement of the second knee fitting 70 along the groove 54 of the knee base member 50 when the knee base member 50 and the second knee fitting 70 connected to each other are in a posture different from a predetermined relative posture (second relative posture). The restraining portion 73 restrains the movement of the second knee fitting 70 along the groove 54 relative to the knee base member 50 by contacting the knee base member 50 when the knee base member 50 and the second knee fitting 70 connected to each other are in a posture different from a predetermined relative posture (second relative posture). As a result, the second knee fitting 70 can be made difficult to be separated from the knee base member 50.

[0061] Here, if Figure 5A As shown, in the knee base member 50, the groove 52 of the upper part 50a and the groove 54 of the lower part 50b may be opened toward the same side surface 55 (surface on the +Z direction side). The extending direction of the groove 52 of the upper part 50a and the extending direction of the groove 54 of the lower part 50b may be parallel.

[0062] In addition, the knee joint 108 further includes a third knee member 80 (third member) connected to the first knee member 60. Figure 7A to Figure 7B , the connection between the first knee accessory 60 and the third knee accessory 80 is described. Fig. 7A The first knee fitting 60 and the third knee fitting 80 are shown in a state where they are separated. Figure 7B The state in which the first knee fitting 60 and the third knee fitting 80 are connected is shown.

[0063] The first knee fitting 60 has a clamping portion 60b that clamps a portion 80a of the third knee fitting 80, and has a protrusion 65 (third protrusion) on the inner side surface 64 of the clamping portion 60b. The protrusion 65 engages with a groove 82 (third groove) provided on the outer side surface 81 of the portion 80a of the third knee fitting 80, and serves as a rotation axis when the first knee fitting 60 and the third knee fitting 80 rotate relative to each other. In the present embodiment, the protrusions 65 are provided on two inner side surfaces 64 that face each other in the clamping portion 60b of the first knee fitting 60.

[0064] The groove 82 of the third knee fitting 80 is provided on the outer side surface 81 of a portion 80a sandwiched by the clamping portion 60b of the first knee fitting 60, and extends in one direction starting from the rotation axis when the first knee fitting 60 rotates. That is, the outer side surface 81 of the third knee fitting 80 is formed into a letter C shape by the groove 82 open in one direction. In the present embodiment, the groove 82 is respectively provided on two outer side surfaces 81 on opposite sides of the portion 80a of the third knee fitting 80.

[0065] The connection between the first knee member 60 and the third knee member 80 is performed in a state where the first knee member 60 and the third knee member 80 are in a predetermined relative posture (third relative posture). Fig. 7A As shown, the predetermined relative posture of the first knee fitting 60 and the third knee fitting 80 refers to the relative posture of the first knee fitting 60 and the third knee fitting 80 when the angle ε between the imaginary line Le extending in the longitudinal direction of the first knee fitting 60 and the imaginary line Lg extending in the longitudinal direction of the third knee fitting 80 is a predetermined angle. The predetermined angle is a value less than 90 degrees (preferably less than 60 degrees, more preferably less than 45 degrees). In the state where the first knee fitting 60 and the third knee fitting 80 are in the predetermined relative posture, the first knee fitting 60 is moved relative to the third knee fitting 80 along the groove 82 of the third knee fitting 80, so that the protrusion 65 of the first knee fitting 60 is engaged with the groove 82.

[0066] After the protrusion 65 of the first knee fitting 60 is engaged with the groove 82 of the third knee fitting 80, Figure 7BAs shown, the third knee fitting 80 is rotated relative to the first knee fitting 60 with the protrusion 65 as the rotation axis A5 (center). As a result, the third knee fitting 80 is connected to the first knee fitting 60. The first knee fitting 60 is provided with a restraining portion 66 (restricting portion) for restraining (restricting) the movement of the first knee fitting 60 along the groove 82 of the third knee fitting 80 when the first knee fitting 60 and the third knee fitting 80 connected to each other are in a posture different from the predetermined relative posture (third relative posture). The restraining portion 66 restrains the movement of the first knee fitting 60 relative to the third knee fitting 80 along the groove 82 by contacting the third knee fitting 80 when the first knee fitting 60 and the third knee fitting 80 connected to each other are in a posture different from the predetermined relative posture (third relative posture). As a result, the first knee fitting 60 and the third knee fitting 80 can be prevented from being separated from each other.

[0067] Various exterior components are attached to the knee joint 108 assembled as described above. This prevents the components of the knee joint 108 from being separated, and the leg 104 (left leg 104a) of the model toy 100 can be constructed.

[0068] In the knee joint part 108 of the present embodiment, through the above-mentioned structure, similar to the elbow joint part 107, in addition to expanding the movable area of ​​​​extension and flexion, it is also possible to facilitate the assembly of multiple accessories (knee base component 50, first knee accessory 60, second knee accessory 70, third knee accessory 80) constituting the knee joint part 108, and make it difficult for the multiple accessories to detach after assembly.
