Any combination of two or more features described in the embodiments may be used. Additionally, identical or identical structures are labeled with the same reference numerals, and redundant descriptions are omitted.

[0025] <Appearance of model toys>

[0026] Reference Figure 1 An example of the appearance structure of the model toy 100 of this embodiment will be described. Figure 1This shows the front view of model toy 100. Furthermore, the x-arrow indicates the left-facing direction of the model toy, the y-arrow indicates the upward-facing direction, and the z-arrow indicates the front-facing direction; the same applies to the other figures.

[0027] The model toy 100 comprises a head 101, a chest 102, arms 103a and 103b, a waist 104, legs 105a and 105b, and wings 106a and 106b, forming the main body. In this embodiment, a humanoid robot is used as an example of a model toy, but this is not intended to limit the invention. The invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and decorative items.

[0028] The head 101 is rotatably connected to the chest 102. The chest 102 also has a right arm 103a and a left arm 103b connected to its sides via shoulder joints, and a waist 104 connected to its lower part. The waist 104 includes a hip joint, and a right leg 105a and a left leg 105b are rotatably connected to it.

[0029] Wings 106a and 106b are decorative parts (model components) of the model toy 100 connected to the rear side of the chest 102. Each wing 106a and 106b is movable relative to the main body, and can move within each wing to an open state (wing extended) and a closed state (wing closed). Furthermore, each wing 106a and 106b includes a fine-tuning thruster as a decorative component. Here, a fine-tuning thruster refers to a device that corresponds to a jet nozzle used in rockets or similar devices and controls the attitude of the machine. In this embodiment, each wing 106a and 106b of the model toy 100 includes a model component that mimics the aforementioned jet nozzle. Additionally, the jet nozzle in this embodiment has a movable mechanism. This movable mechanism will be described in detail below.

[0030] <Wing Shape>

[0031] Reference Figure 2 An example of the structure of the wing in this embodiment will be described. Figure 2 (a) represents the front view of the decorative section 106, including the wings 106a and 106b. Figure 2 (b) represents an exploded perspective view of wing 106b.

[0032] like Figure 2As shown in (a), the decorative part 106, in addition to the wings 106a and 106b, also has a connecting part 106c. The connecting part 106c is rotatably connected to the wings 106a and 106b on the left and right sides respectively, and is further connected to the back of the model toy 100. The structure of the wing 106b will be described below, but the wing 106a is also symmetrical to the wing 106b, so the description is omitted.

[0033] Figure 2 (b) shows an exploded perspective view of wing 106b. Wing 106b is configured to include wings 201a and 201b, a propeller section 202, and a connecting section 203. Each part is composed of multiple components. Wings 201a and 201b are rotatably connected to the left and right sides of the propeller section 202, respectively. Connecting section 203 is connected to the upper part of the propeller section 202. Connecting section 203 is rotatably connected to connecting section 106c. Furthermore, wing 106b can move between an open state (wings 201a and 201b open) and a closed state (wings 201a and 201b closed) via a movable structure of the connecting sections of wings 201a and 201b provided on both sides of the propeller section 202. Regarding the wing's mobility, [the following is used...] Figure 4 This will be discussed later.

[0034] <Structure of the propulsion section>

[0035] Reference Figure 3 The detailed structure of the thruster section 202 in this embodiment will be described. Figure 3 This is an exploded perspective view of the thruster section 202.

[0036] like Figure 3 As shown, the propulsion unit 202 is configured to include fittings 301 to 310b. The propulsion unit 202 includes fittings 301 to 305d that simulate a jet nozzle. First, the structure of the jet nozzle fitting will be described. Fitting 301 is a rod-shaped first fitting (nozzle), formed having a first portion with a thinner tip and a second portion with a diameter longer than the first portion. Additionally, fitting 301 has a first protrusion on its outer peripheral surface. Fitting 301 passes through fittings 302 and 303 and is connected to fitting 304.

[0037] Accessory 302 is an example of the second accessory; it is a cylindrical accessory with a hollow portion that receives accessory 301, and accessory 303 is connected to its lower end in the figure. Accessory 303 is an example of the third accessory; it has an opening through which accessory 301 passes, and also has connecting portions for accessories 305a to 305d to be rotatably connected. Accessories 305a to 305d are examples of the fourth accessory; they are connected to cover accessory 304 and form blade portions (fins) at the front end of the injection nozzle. Accessory 304 is an example of the fifth accessory.

[0038] Accessories 306a and 306b are installed by clamping them into accessories 301 to 305d, which constitute the jet nozzle, from both sides. This prevents accessories 301 to 305d from detaching. Accessory 310a is installed in accessory 306a, and accessory 310b is installed in accessory 306b. Wing 201a is rotatably connected to accessory 310a, and wing 201b is rotatably connected to accessory 310b. Accessories 310a and 310b themselves are composed of multiple folded accessories, which can be rotated by unfolding them, and wings 201a and 201b can move between open and closed states. Furthermore, as part of the external accessories of the propeller section 202, accessories 307 and 308 are installed from the front, and accessory 309 is installed from the rear.

[0039] <Wing Mobility>

[0040] Reference Figure 4 The movable structure of the wing in this embodiment will be described. Figure 4 of (a) Figure 4 (b) shows the rear view of wing 106b. Furthermore, wing 106a is omitted from the description as it has the same structure as wing 106b.

[0041] Figure 4 (a) indicates the closed state that closes the wings 201a and 201b of the wing 106b. Figure 4 (b) is from Figure 4 The closed state of (a) causes wings 201a and 201b to rotate and open. Components 310a and 310b are each composed of multiple components, and by rotating each component, wings 201a and 201b can be rotated.

[0042] like Figure 4 As shown in (b), when the wings 201a and 201b are changed from the closed state to the open state, the propeller section 202 is exposed. In this state, the propeller section 202 can be operated to move the jet nozzle section between the closed state and the open state. The detailed movable mechanism will be described later.

[0043] <Structure of the jet nozzle>

[0044] Reference Figure 5 The structure of the injection nozzle in this embodiment will be described. Figure 5 (a) represents a perspective view of the thruster section 202. Figure 5 (b) represents a perspective view of the injection nozzle 500. Furthermore, in Figure 5 In (a), for ease of explanation, the state of accessories 307 to 309 as external accessories after disassembly is indicated.

[0045] like Figure 5 As shown in (a), the propulsion section 202 includes a jet nozzle 500. As described above, the jet nozzle 500 is configured to include fittings 301 to 305d. Fittings 306a and 306b are mounted relative to the jet nozzle 500 from both sides. Openings are formed in fittings 306a and 306b, exposing the second protrusion 621a of fitting 302 in an operable manner. Furthermore, although not shown, the second protrusion 621b, located on the rear side of fitting 306b, is also exposed through the opening in an operable manner. By rotating the second protrusions 621a and 621b, the jet nozzle 500 can be changed from a closed state to an open state. Alternatively, either the second protrusion 621a or 621b may be formed.

[0046] Figure 5 (b) indicates the injection nozzle 500 after being removed from the propeller section 202. A groove 622 is formed spirally (inclined) on the side wall of the fitting 302. A first protrusion 611 formed on the side of the fitting 301 is inserted into this groove 622. In this state, when the fitting 302 is rotated in the direction of the arrow by means of the second protrusions 621a and 621b, the first protrusion 611 is guided to move by the groove 622. The groove 622 is formed in the direction of the front end of the injection nozzle 500 (opposite to the y direction in the figure). Therefore, the fitting 301, as the first fitting, slides in the direction of the front end of the injection nozzle 500. This front end direction is referred to as the length direction or sliding direction of the fitting 301.

[0047] Here, refer to Figure 6 The sliding action of accessory 301 is explained. Figure 6 (a) indicates accessories 301 and 302 before the action. Figure 6 (b) indicates accessories 301 and 302 after the action.

[0048] exist Figure 6In state (a), the second protrusions 621a and 621b are rotated in the direction of the arrow. As a result, the accessory 302 rotates in the opposite direction to the x-direction in the figure, and the position of the groove 622 also moves. Figure 6 As shown in (b), the groove 622 from Figure 6 The position of (a) moves, and the first protrusion 611 of the accessory 301 is guided by the groove 622 to move in the direction of the arrow. As a result, the accessory 301 moves (slides) in the opposite direction (sliding direction) of the y direction in the figure.

[0049] <Assembly structure of blade section (fin)>

[0050] Reference Figure 7 The structure of the blade portion at the front end of the injection nozzle 500 in this embodiment will be described. Figure 7 This indicates the situation where accessory 305a is installed relative to accessory 303.

[0051] Fitting 303 has an opening 731 through which fitting 301 passes, and recesses 732a-732d for connecting fittings 305a-305d. Recesses 732a-732d are formed on the outer periphery of one end of fitting 303. Additionally, fitting 305a has a third protrusion 751a and a connecting portion 752a, fitting 305b has a third protrusion 751b and a connecting portion 752b, fitting 305c has a third protrusion 751c and a connecting portion 752c, and fitting 305d has a third protrusion 751d and a connecting portion 752d. Figure 7 The diagram shows the connecting portion 752b of accessory 305b rotatably connected to the recess 732b of accessory 303. When the connecting portion 752b rotates in the direction of the arrow, the blade portion of accessory 305b rotates in the direction of the arrow.

[0052] The rotation of the connecting portion 752b is achieved by pressing the third protrusion 751b by the fitting 301. The third protrusion 751b of the fitting 305b is exposed in the opening 731 through the opening 731. The fitting 301 presses the exposed portion through the opening 731. As a result, the fitting 305b rotates in an outward opening manner. On the other hand, when the third protrusion 751b is pressed from the opposite side, the fitting 305b rotates in a closing direction. Similarly to the fitting 305b, the connecting portion 752a of the fitting 305a is also rotatably connected to the recess 732a, the connecting portion 752c of the fitting 305c is also rotatably connected to the recess 732c, and the connecting portion 752d of the fitting 305d is also rotatably connected to the recess 732d.

[0053] <Action of the jet nozzle>

[0054] Reference Figure 8 The operation of the injection nozzle 500 in this embodiment will be explained. Figure 8 of (a) Figure 8 (b) represents a three-dimensional view of the injection nozzle 500. Figure 8 (c) represents a side view of the injection nozzle. Furthermore, in Figure 8 For ease of explanation, the image is shown with some parts disassembled.

[0055] Figure 8 (a) indicates the closed state of the spray nozzle 500 after the accessories 302, 304, and 305d of the spray nozzle 500 have been disassembled. Here, the closed state of the spray nozzle refers to the state in which accessories 305a to 305d are closed. In this state, a portion (first portion) of accessory 301 is located between the third protrusions 751a to 751d of each accessory 305a to 305d. The first portion of accessory 301 is formed to have a first diameter l1. This first diameter l1 is defined as the length that can pass through the inside of the portion of accessory 305a to 305d where the third protrusions 751a to 751d are located in the closed state. That is, the first portion of accessory 301 is formed to not contact the third protrusions 751a to 751d.

[0056] Figure 8 (b) indicates from Figure 8 In the case where the closed state of component 302 has been rotated, component 301 slides in the opposite direction of the y-direction in the figure, and components 305a to 305d are in the open state. In the open state, component 301 moves forward, and a portion of component 301 (the second portion) contacts and is pressed out by the third protrusions 751a to 751d, and components 305a to 305d rotate in the direction of the arrow. The second portion of component 301 is formed to have a second diameter l2. This second diameter l2 is defined as the length of the portion of component 305a to 305d that abuts against the portion where the third protrusions 751a to 751d are located in the closed state. That is, the second portion of component 301 is formed to contact the third protrusions 751a to 751d in the closed state.

[0057] Furthermore, a component 304 is connected to the front end of component 301. Therefore, when the rotation of component 302 is revoked, component 301 slides in the y-direction shown in the figure, and the end of component 304 abuts against the third protrusions 751a-751d of components 305a-305d in the open state, pressing them back and returning components 305a-305d to the closed state. The aforementioned end of component 304 is formed to have a third diameter l3. This third diameter l3 is defined as the length that contacts the portion of components 305a-305d where the third protrusions 751a-751d are located in the open state. In other words, the aforementioned end of component 304 is formed to contact the third protrusions 751a-751d.

[0058] Figure 8 (c) shows the first diameter l1 to the third diameter l3. Furthermore, the dotted line in the figure is drawn along the length of the second diameter l2. It can be seen that the first diameter l1 at the first part of the fitting 301 is defined as the length between the third protrusions 751c and 751d in the closed state. Additionally, the second diameter l2 at the second part of the fitting 301 is defined to be longer than the length between the third protrusions 751c and 751d in the closed state, that is, longer than the first diameter l1. Therefore, it can contact the third protrusion.

[0059] Furthermore, the aforementioned end of accessory 304 is specified to be longer than the first diameter l1 and also longer than the second diameter l2. This is because the aforementioned end of accessory 304 contacts accessories 305a-305d when they are open, i.e., because the aforementioned end of accessory 304 is specified to be the length that allows it to contact the third protrusions 751a-751d when they are rotated open. Therefore, the diameters are specified to be in the relationship of first diameter l1 < second diameter l2 < third diameter l3.

[0060] As explained above, the model toy of this embodiment includes: a first rod-shaped accessory having a first protrusion on its side; and a second cylindrical accessory having a hollow portion through which the first accessory passes, a second protrusion for rotational operation, and a groove formed on its side wall to guide the movement of the first protrusion. Furthermore, when the second accessory is rotated via the second protrusion, the first protrusion of the first accessory moves in the groove, and the first accessory slides in the longitudinal direction. Additionally, the model toy also includes: a third accessory connected to the end of the second accessory and having a recess and an opening through which the first accessory passes; and a fourth accessory rotatably connected to the recess of the third accessory and having a third protrusion. In this case, when the first accessory slides in the longitudinal direction, pressing the third protrusion causes the fourth accessory to rotate relative to the third accessory. Therefore, according to this embodiment, by rotating the second component, the first component (nozzle) can slide, thereby causing the fourth component (fin) to rotate into the open state in conjunction. Thus, according to this embodiment, a new structure for the movable mechanism in a model toy can be provided.

[0061] <Variation Example>

[0062] This invention is not limited to the embodiments described above, and various modifications and alterations can be made within the scope of the invention's intent. For example, the shape of the model toy is not particularly limited, and includes a wide variety of shapes such as humans, animals, robots, insects, and dinosaurs. Furthermore, in the above embodiments, a model component (wing) that can be attached to or detached from the back of the model toy was described as an example, but this is not intended to limit the components or positions that can be attached to the model toy. For example, other clothing components, protective gear components, weapon components, etc., could also be used.
