[0025] Hereinafter, embodiments will be described in detail based on the accompanying drawings. Furthermore, in all the drawings used to describe the embodiments, components with the same function will be labeled with the same reference numerals, and repeated descriptions will be omitted. Additionally, in the following embodiments, descriptions of the same or identical parts will generally not be repeated unless specifically required.

[0026] A toy according to one embodiment of the present invention is described with reference to the accompanying drawings. Figures 1-4 This is a perspective view of toy 1 according to this embodiment. Figure 1 and Figure 2 Toy 1 is shown with its mouth closed. Figure 3 and Figure 4Toy 1 is shown with its mouth open. Additionally, in... Figure 1 and Figures 2-4 In the middle, observe the different directions of toy 1.

[0027] Figures 1-4 The toy 1 of this embodiment shown includes: a jaw member (simulated jaw, virtual jaw) 2 that imitates the lower jaw, a jaw member (simulated jaw, virtual jaw) 3 that imitates the upper jaw, a support platform (main body) 4 that supports the jaw members 2 and 3, a plurality of tooth members (simulated teeth, virtual teeth) 5 that respectively imitate teeth, and a rod 6. Figures 1-4 The toy 1 of this embodiment shown also includes a component mimicking a toothbrush (simulated toothbrush, virtual toothbrush) 11, a component mimicking a dental tool (simulated dental tool, virtual dental tool) 12, and a component mimicking a cup (simulated cup, virtual cup) 13. These structural elements of the toy 1 can be formed primarily using materials such as resin. In the detailed description, for convenience, [the following will be used]. Figures 1-4 The side of the toy 1 that mimics the upper jaw 2 is described as "upper," and the side of the toy that mimics the lower jaw 3 is described as "lower." The other figures are described in the same way.

[0028] Jaw member 2 is mounted on and fixed to support platform 4. Jaw member 3 is mounted in a manner that allows it to rotate relative to jaw member 2. Multiple tooth members 5 are mounted on jaw member 2 in a manner that allows them to rotate.

[0029] By moving jaw member 3 relative to jaw member 2, jaw member 2 and jaw member 3 can be changed to a closed mouth state. Figure 2 (state) and open mouth state ( Figure 3 More specifically, by rotating the jaw member 3 around the axis of rotation that holds the jaw member 3 relative to the jaw member 2, the jaw member 2 and jaw member 3 can be changed to a closed mouth state. Figure 2 (state) and open mouth state ( Figure 3 (State).

[0030] The head is formed by jaw member 2 and jaw member 3. In addition, the main body 7 is installed in the support platform 4 at a position adjacent to jaw member 2.

[0031] The lever 6 is mounted on the jaw member 2 or the support platform 4. By moving the lever 6, the jaw member 3 can move relative to the jaw member 2 (more specifically, rotate). Specifically, when the lever 6 is pulled forward (laid down), the jaw member 2 and the jaw member 3 are in an open mouth state. Figure 3 When the lever 6 is retracted inward (erected), jaw members 2 and 3 are in a closed mouth state. Figure 2 (State).

[0032] When jaw components 2 and 3 are in an open mouth state ( Figure 3 When the jaw members 2 and 3 are in a closed mouth state, the multiple toothed members 5 installed on the jaw member 2 are exposed, making them visible to the user of the toy 1. Conversely, when the jaw members 2 and 3 are in a closed mouth state... Figure 2 When the toy is in a certain state, the multiple toothed components 5 installed on the jaw component 2 are hidden in the jaw component 3 and become invisible to the user of the toy 1.

[0033] Multiple toothed members 5 are mounted on the jaw member 2, each with a defined surface exposed from the jaw member 2. Multiple toothed members 5 are arranged along the outer periphery of the jaw member 2 on the upper surface side of the jaw member 2. The toothed members 5 are not completely fixed to the jaw member 2, but are mounted to the jaw member 2 in a rotatable manner. Figure 5 This is a cross-sectional view of the toothed component 5 used in toy 1. Figure 5 In the sectional view, the toothed member 5 is able to rotate about the rotation axis 21. Figure 5 In the middle, the rotation axis 21 extends in a direction approximately perpendicular to the paper surface. The tooth component 5 has a surface 5a that imitates a carious tooth and a surface 5b that imitates a non-carious tooth.

[0034] The multiple toothed members 5 installed on the jaw member 2 can be changed to a state in which the surface 5a of the toothed member 5 is exposed from the jaw member 2 according to the operation of the user of the toy 1. Figure 3 The state of exposing the surface 5b of the tooth member 5 from the jaw member 2. Figure 4 (State). In a state where the surface 5a of the tooth member 5 is exposed from the jaw member 2 ( Figure 3 In the state of ( ), the surface 5a, which mimics the tooth decay, becomes the upper surface of the tooth member 5, and in the state of exposing the surface 5b of the tooth member 5 from the jaw member 2 ( ). Figure 4 In the state where the tooth member 5a is exposed from the jaw member 2, the surface 5b, which mimics the surface of a non-caries tooth, becomes the upper surface of the tooth member 5. Figure 3 The state of exposing the surface 5b of the tooth member 5 from the jaw member 2. Figure 4 In the state of ( ), the rotational position of the tooth member 5 is different. In other words, by rotating the tooth member 5, the rotational position is changed, thereby making the exposed surface of the tooth member 5 from the jaw member 2 change to either surface 5a or surface 5b.

[0035] The toothed member 5 includes an outer member (shell member) 22 constituting the outer periphery of the toothed member 5 and an inner member 23 disposed inside the outer member 22 in a manner covered by the outer member 22 (see reference). Figure 5The outer member 22 has a different color from the inner member 23. On the surface 5a of the tooth member 5, an opening (through hole) 24 is provided in the outer member 22, exposing the inner member 23, which has a different color from the outer member 22. That is, when the surface 5a of the tooth member 5 is exposed from the jaw member 2, the user can visually identify the inner member 23, which has a different color from the outer member 22, through the opening 24. However, on the surface 5b of the tooth member 5, no opening is provided in the outer member 22 to expose the inner member 23. Therefore, when the surface 5b of the tooth member 5 is exposed from the jaw member 2, the inner member 23 is covered by the outer member 22 and is not exposed from the outer member 22. Therefore, the user cannot visually identify the inner member 23 from the surface 5b of the tooth member 5. In other words, when the surface 5a of the tooth member 5 is exposed from the jaw member 2, the inner member 23 is exposed from the outer member 22; when the surface 5b of the tooth member 5 is exposed from the jaw member 2, the inner member 23 is covered by the outer member 22. Thus, the surface 5a of the tooth member 5 looks like a carious tooth, while the surface 5b of the tooth member 5 looks like a non-carious tooth.

[0036] In general, the shape of the tooth member 5 (and thus the shape of the outer member 22) is, for example, generally cuboid (more specifically, generally cubic). When the tooth member 5 rotates, any one of the four faces of the tooth member 5 that are generally parallel to the axis of rotation 21 becomes the upper surface and can be exposed from the jaw member 2. Two of the four faces that are generally parallel to the axis of rotation 21 become faces 5a that mimic caries, and the other two become faces 5b that mimic non-caries teeth. In the tooth member 5, the faces 5a that mimic caries are located on opposite sides of each other, and the faces 5b that mimic non-caries teeth are located on opposite sides of each other (see reference). Figure 5 ).

[0037] Here, the rotational position of the tooth member 5 is referred to as the "rotational position of the tooth" when the surface 5a, which mimics a carious tooth, is exposed from the jaw member 2, i.e., when the surface 5a, which mimics a carious tooth, becomes the upper surface of the tooth member 5 and is exposed from the jaw member 2. Conversely, the rotational position of the tooth member 5 is referred to as the "rotational position of the non-carious tooth" when the surface 5b, which mimics a non-carious tooth, is exposed from the jaw member 2, i.e., when the surface 5b, which mimics a non-carious tooth, becomes the upper surface of the tooth member 5 and is exposed from the jaw member 2. The user of the toy 1 can see the surface exposed from the jaw member 2 as the upper surface of the tooth member 5; therefore, the tooth member 5 in the rotational position of the carious tooth looks like a carious tooth, and the tooth member 5 in the rotational position of the non-carious tooth looks like a non-carious tooth. When the tooth member 5, which is located in the rotational position of the carious tooth, is rotated by 90°, the tooth member 5 becomes the rotational position of the non-carious tooth. When the tooth member 5 is rotated by 90° further, the tooth member 5 becomes the rotational position of the carious tooth. When the tooth member 5 is rotated by 90° further, the tooth member 5 becomes the rotational position of the non-carious tooth. When the tooth member 5 is rotated by 90° further, the tooth member 5 becomes the rotational position of the carious tooth.

[0038] Figures 1-4 The toy 1 of this embodiment also includes a component 11 that imitates a toothbrush, a component 12 that imitates a dental tool, and a component 13 that imitates a cup. Figures 1-4 In this case, component 12, which imitates a dental tool, is a component that imitates a dental drill bit. Components 11, 12, and 13 are respectively disposed in the hole (recess) provided in the support base 4, and can be removed from the support base 4.

[0039] The user of toy 1 can rotate the toothed member 5 by pressing the toothbrush-like component 11 against it and applying rotational force to the toothed member 5 using component 11. Alternatively, the user can press the dental tool-like component 12 against the toothed member 5 instead of the toothbrush-like component 11 and apply rotational force to the toothed member 5 using component 12, thus rotating the toothed member 5. Therefore, components 11 and 12 can be considered as rotational operating components that can be pressed against and rotated by the user of toy 1. Component 13 mimics a cup used for brushing teeth and is not used to rotate the toothed member 5. Therefore, the cup-like component 13 can be fixed to the support base 4, or it can be omitted.

[0040] like Figure 3 and Figure 4 As shown, when jaw members 2 and 3 are in an open mouth state, member 11 or member 12 can be easily inserted into the mouth, and member 5 can be rotated by pressing member 11 or member 12 against member 5. Furthermore, as... Figure 1 and Figure 2As shown, when jaw members 2 and 3 are in a closed mouth state, it is not easy, or impossible, to insert member 11 or member 12 into the mouth. Therefore, the action of pressing member 11 or member 12 against tooth member 5 to rotate tooth member 5 is not like... Figure 1 and Figure 2 When jaw components 2 and 3 are in a closed mouth state, it is like... Figure 3 and Figure 4 When the jaw components 2 and 3 are in an open mouth state, it is done by the user of toy 1.

[0041] Figure 6 and Figure 7 This is an explanatory diagram illustrating the mechanism for positioning the rotational position of the toothed component 5.

[0042] like Figure 6 and Figure 7 As shown, the tooth member 5 has a square-shaped plate member 32 located on its side (the side substantially perpendicular to the rotation axis 21). Furthermore, the planar shape of the plate member 32 corresponds to the shape of the face substantially perpendicular to the rotation axis 21. The four sides of the square-shaped plate member 32 are parallel to the four faces (5a, 5b) of the tooth member 5 substantially perpendicular to the rotation axis 21. This plate member 32 is fixed to or integrally formed with the outer member 22 of the tooth member 5; therefore, when the tooth member 5 rotates, the plate member 32 also rotates. The rotation axis 21 passes through a hole located near the center of the plate member 32. Additionally, as... Figure 6 and Figure 7 As shown, two rod-shaped members 33 (one referred to as member 33a and the other as member 33b) extending in the vertical direction (from the upper jaw member 2 toward the lower jaw member 3) are installed on the jaw member 2, forming a plate member 32 sandwiched between these two members 33 (33a and 33b). The lower parts of members 33a and 33b ( Figure 6 and Figure 7 The portion hidden by the jaw member 2 is connected and fixed to the jaw member 2.

[0043] Since the square-shaped plate member 32 is sandwiched between members 33a and 33b, therefore, as Figure 6 As shown, when two sides of the square-shaped plate member 32 are parallel to the extending directions (vertical direction) of the rod-shaped members 33a and 33b, the two sides are in approximately complete contact with members 33a and 33b, thus the square-shaped plate member 32 is stably sandwiched between members 33a and 33b. Therefore, in Figure 6 In this state, the rotational position of the toothed component 5 is stable, and even if a small external force (rotational force) is applied to the toothed component 5, the rotational position of the toothed component 5 will not change.

[0044] In addition, such as Figure 7 As shown, when the sides of the square-shaped plate member 32 are inclined relative to the extending direction (vertical direction) of the rod-shaped members 33a and 33b, the corners of the square-shaped plate member 32 contact the rod-shaped members 33a and 33b, resulting in an increased gap between the rod-shaped members 33a and 33b. Therefore, the rod-shaped members 33a and 33b, with their increased gap, become flexed (bent), and the rod-shaped members 33a and 33b forcefully press against the corners of the square-shaped plate member 32. Thus, in Figure 7 In this state, the rotational position of the toothed component 5 is unstable. By applying only a slight external force (rotational force), it will automatically... Figure 7 The state is like Figure 6 As shown, the two sides of the plate member 32 are parallel to the extension direction of the rod-shaped members 33a and 33b.

[0045] Therefore, as Figure 6 As shown, the rotational position of the toothed member 5 is restricted to a state where the two sides of the plate member 32 are parallel to the extending directions of the rod-shaped members 33a and 33b. That is, the rotational position of the toothed member 5 is restricted to... Figure 6 The rotational positions of the tooth member 5 are shown in the diagram: the rotational position of a carious tooth, the rotational position from which the tooth member 5 rotates 90° (the rotational position of a non-carious tooth), the rotational position from which the tooth member 5 rotates further 90° (the rotational position of a carious tooth), and the rotational position from which the tooth member 5 rotates further 90° (the rotational position of a non-carious tooth), and these rotational positions can be stably maintained. The plate member 32 and the rod-shaped members 33a and 33b can function as limiting parts that restrict the rotational position of the tooth member 5. Therefore, when the tooth member 5 is provided with multiple exposed surfaces, including a surface 5a that imitates a carious tooth and a surface 5b that imitates a non-carious tooth, such that one surface can be exposed from the jaw member 2 depending on the rotational position, the plate member 32 and the rod-shaped members 33a and 33b can limit the rotation of the tooth member 5 to the position where any one of the multiple exposed surfaces (5a, 5b) is exposed from the jaw member 2.

[0046] In addition, as Figure 6 and Figure 7 As shown, in the tooth component 5, a protrusion (protrusion portion) 31 is provided on the surface 5a that imitates a decayed tooth. Figure 6 and Figure 7In this case, protrusions 31 are provided near the four corners of the surface 5a that imitates a tooth decayed tooth, thus providing four protrusions 31 on each surface 5a. The protrusions 31 correspond to the portions of the outer member 22 of the tooth member 5 that protrude outward from the curved surface representing the appearance of a tooth. The brush surface (the surface of the part that imitates a brush) of the toothbrush member 11 is not a flat surface, but a serrated surface (concave-convex surface). The user of the toy 1 can change the tooth member 5 from the tooth decayed rotation position to the non-tooth decayed rotation position by pressing the brush surface of the toothbrush member 11 onto the tooth decayed ... Therefore, the protrusion 31 on the tooth-imitating tooth surface 5a of the tooth member 5 can become the operated part for the user of the toy 1 to rotate the tooth member 5. That is, the user of the toy 1 performs an action (operation) to change the state from the state where the tooth member 5 surface 5a is exposed from the jaw member 2 (the state where the tooth member 5 is in the tooth-imitating rotation position) to the state where the tooth member 5 surface 5b is exposed from the jaw member 2 (the state where the tooth member 5 is in the non-tooth-imitating rotation position), and the protrusion 31 can become the operated part of this action (operation). Since the protrusion 31 is provided on the tooth-imitating tooth surface 5a of the tooth member 5, the tooth member 5 can be easily and reliably changed from the tooth-imitating rotation position to the non-tooth-imitating rotation position by using the toothbrush-imitating member 11, etc. Furthermore, when a component 12 that mimics a dental tool (here, a dental drill bit) is used instead of a component 11 that mimics a toothbrush, the protrusion 31 can also act as the operated part, allowing the tooth component 5 to easily and reliably change from a tooth decay position to a non-tooth decay position. In addition, by inserting the tip of the drill bit into the opening 24 of the outer component 22 of the tooth component 5, the component 12 that mimics a dental tool can also easily and reliably impart rotational force to the tooth component 5.

[0047] Figure 8 and Figure 9 This is an explanatory diagram illustrating the mechanism by which jaw components 2 and 3 change to an open mouth state and a closed mouth state. Figure 8 and Figure 9 It is a 3D view showing a portion of Toy 1 through perspective. Figure 8 In the middle, jaw components 2 and 3 are in a closed mouth state. Figure 9 In the middle, jaw components 2 and 3 are in an open mouth state.

[0048] When lever 6 is actuated, the rotating shaft (not shown) connected to lever 6 and the gear (not shown) fixed to the rotating shaft rotate, thereby rotating the pinion (gear) 42 meshing with the gear. A rack (plate-shaped or rod-shaped gear) 41 is arranged adjacent to the pinion 42, and the teeth of the pinion 42 mesh with the teeth of the rack 41. Therefore, when the pinion 42 rotates, the rack 41 can move in a straight line (here, in the vertical direction), converting the rotational motion of the pinion 42 into the linear motion of the rack 41. The upper end of the rack 41 is connected to the jaw member 3. Using the linear motion (vertical movement) of the rack 41, the jaw member 3 can move, thereby changing the jaw members 2 and 3 into an open-mouth state and a closed-mouth state.

[0049] For example, such as Figure 8 As shown, with lever 6 in the upright position, jaw components 2 and 3 are in a closed mouth state, but as... Figure 9 As shown, when lever 6 is lowered towards the front, rack 41 descends in response to the rotation of pinion 42, thereby actuating jaw member 3 and causing jaw members 2 and 3 to open their mouths. On the other hand, as... Figure 9 As shown, with lever 6 tilted forward, jaw components 2 and 3 are in an open mouth state, but as... Figure 8 As shown, when the lever 6 is raised (retracted) inward, the rack 41 rises in response to the rotation of the pinion 42, thereby causing the jaw member 3 to move and the jaw members 2 and 3 to be in a closed state.

[0050] in addition, Figure 8 and Figure 9 The gear (small gear) 43 shown meshes with a gear (not shown) fixed to a rotating shaft (not shown) connected to the lever 6. When the lever 6 is turned, the gear 43 also rotates.

[0051] As described above, when jaw members 2 and 3 are in an open mouth state, each tooth member 5 can be changed to a state where the surface 5a of the tooth member 5 is exposed from the jaw member 2, depending on the operation of the user of the toy 1. Figure 3 The state of the tooth member 5 and the state of the surface 5b of the tooth member 5 exposed from the jaw member 2. Figure 4 In other words, when jaw components 2 and 3 are in an open mouth state, each tooth component 5 can change to the rotational position of the tooth according to the operation of the user of the toy 1. Figure 3 Rotation position of teeth with and without caries (rotation position of teeth with and without caries) Figure 4 (The rotational position). Moreover, as described below, the jaw components 2 and 3, which were in an open mouth state, changed to a closed mouth state ( Figure 1 and Figure 2Corresponding to the state of the jaw member 2, the multiple tooth members 5 installed on the jaw member 2 are all in a state where the surface 5a of the tooth member 5 is exposed from the jaw member 2 (specifically, the surface 5a mimicking a carious tooth becomes the upper surface of the tooth member 5). In other words, the jaw members 2 and 3, which are in an open mouth state, are changed to a closed mouth state. Figure 1 and Figure 2 Correspondingly, in the state of the tooth, the multiple tooth components 5 installed on the jaw component 2 all become the rotational position of the tooth. (Refer to...) Figure 10 and Figure 11 Here is an example of an organization that implements it.

[0052] Figure 10 and Figure 11 This is an explanatory diagram illustrating the mechanism by which all the tooth components 5 become the rotating position of the tooth when the jaw components 2 and 3 change from an open mouth state to a closed mouth state. Figure 10 This corresponds to the situation where jaw components 2 and 3 are in an open mouth state. Figure 11 This corresponds to the situation where jaw components 2 and 3 are in a closed mouth state.

[0053] like Figure 10 and Figure 11 As shown, the toothed member 5 has a rod-shaped member 51 provided on its side (the side substantially perpendicular to the rotation axis 21). Furthermore, the toothed member 5 includes the aforementioned plate member 32 (see above). Figure 6 and Figure 7 The side of the ) and the rod-shaped component 51 (see reference) Figure 10 and Figure 11 The sides of the jaw member 5 are opposite to each other. The tooth member 5 is mounted on the jaw member 2, and the side of the tooth member 5 with the rod-shaped member 51 faces the inside of the jaw member 2, while the side of the tooth member 5 with the plate member 32 faces the outside of the jaw member 2. Thus, the rod-shaped or plate-shaped member 52, which will be described later, can be easily arranged on the inside of the jaw member 2.

[0054] The rod-shaped member 51 extends in a direction that is approximately perpendicular to the rotation axis 21 of the tooth member 5 and approximately parallel to the surface 5a that imitates a carious tooth. Since the surface 5a that imitates a carious tooth and the surface 5b that imitates a non-carious tooth are approximately perpendicular to each other, the extension direction of the rod-shaped member 51 is approximately perpendicular to the surface 5b that imitates a non-carious tooth. Because the rod-shaped member 51 is fixed to or integrally formed with the outer member 22 of the tooth member 5, it rotates along with the tooth member 5 when it rotates. The rotation axis 21 passes through a hole located near the center of the rod-shaped member 51.

[0055] Therefore, when the tooth member 5 is in the rotating position of the tooth, the rod-shaped member 51 provided on the side of the tooth member 5 extends in the horizontal direction. In addition, when the tooth member 5 is in the rotating position of the non-tooth, the rod-shaped member 51 provided on the side of the tooth member 5 extends in the vertical direction.

[0056] A rod-shaped or plate-shaped member 52 is arranged adjacent to the toothed member 5, and a protruding portion 53 protruding upward is provided on the upper surface of the member 52. The protruding portion 53 is provided corresponding to each toothed member 5. The member 52 is located in... Figure 10 and Figure 11 It extends in the X direction as shown. Here, the X direction refers to the direction that is approximately perpendicular to the rotation axis 21 of the tooth member 5 and approximately parallel to the side surface of the tooth member 5 (the side surface where the member 51 is located).

[0057] Component 52 is connected to the above Figure 8 and Figure 9 The gear (pinion) 43 shown engages with a rack (not shown). Therefore, the rotational motion of the gear 43 can be converted into linear motion of the member 52 in the X direction. When the lever 6 is turned, the gear 43 also rotates, thereby moving the member 52 in the X direction. Since the protrusion 53 is connected to the member 52, when the member 52 moves in the X direction, the protrusion 53 also moves in the X direction along with it.

[0058] When jaw components 2 and 3 are in the open mouth state (with rod 6 tilted forward), component 52 and protrusion 53 are located Figure 10 As shown in the diagram, when jaw members 2 and 3 are in the closed mouth state (with rod 6 raised), member 52 and protrusion 53 are located at... Figure 11 The position shown. That is, when jaw members 2 and 3 change from an open mouth state to a closed mouth state, member 52 and protrusion 53 move in the X direction from... Figure 10 The position shown is towards Figure 11 The position is moved as shown, and at this time the protrusion 53 passes under the rod-shaped member 51 provided on the side of the tooth member 5.

[0059] When the rod-shaped member 51 extends horizontally (i.e., when the tooth member 5 is in the rotating position of a carious tooth), the protrusion 53 does not collide with the rod-shaped member 51 when it passes below it, thus the tooth member 5 on which the member 51 is mounted does not rotate. However, when the rod-shaped member 51 extends vertically (i.e., when the tooth member 5 is in the rotating position of a non-carious tooth), the protrusion 53 collides with the rod-shaped member 51 when it passes below it, causing the rod-shaped member 51 to rotate 90°, so that its extension direction changes from vertical to horizontal. Because the rod-shaped member 51 rotates 90°, the tooth member 5 on which the member 51 is mounted also rotates 90°, changing from the rotating position of a non-carious tooth to the rotating position of a carious tooth.

[0060] Here, in Figure 10 and Figure 11 In this context, the left toothed component 5 is referred to as toothed component 5c, and the right toothed component 5 is referred to as toothed component 5d. When jaw components 2 and 3 are in an open mouth state, as... Figure 10 As shown, the tooth member 5c uses a component 11 that mimics a toothbrush to change from the rotational position of a carious tooth to the rotational position of a non-carious tooth, while the tooth member 5d maintains the rotational position of a carious tooth.

[0061] With jaw components 2 and 3 open, tooth component 5d... Figure 10 The image shows the position of the tooth decayed area, but even if jaw components 2 and 3 change from an open mouth state to a closed mouth state, as shown... Figure 11 As shown, the tooth component 5d also maintains the rotational position of the decayed tooth. This is because, at the protrusion 53... Figure 10 The position has been moved to Figure 11 When in the correct position, the protrusion 53 does not collide with the rod-shaped member 51 located on the side of the tooth member 5d.

[0062] In contrast, with jaw components 2 and 3 in the open mouth state, tooth component 5c... Figure 10 The image shows a rotating position not associated with tooth decay, but when jaw components 2 and 3 change from an open mouth state to a closed mouth state, as shown... Figure 11 As shown, the tooth component 5c changes from a non-carious rotational position to a carious rotational position. This is because, when the protrusion 53... Figure 10 The position has been moved to Figure 11 When the toothed member 5c is in the correct position, the protrusion 53 collides with and pushes the rod-shaped member 51 located on the side of the toothed member 5c, thereby giving the member 51 a rotational force, and thus the toothed member 5c rotates 90°.

[0063] Therefore, when the jaw members 2 and 3, which are in an open mouth state, change to a closed mouth state by moving the lever 6, the multiple tooth members 5 installed on the jaw member 2 all become the rotation position for tooth decay. That is, when the jaw members 2 and 3 are in an open mouth state, each tooth member 5 can change to a rotation position for tooth decay and a rotation position for non-tooth decay according to the operation of the user of the toy 1 (for example, the operation of the toothbrush-imitating member 11). However, corresponding to the jaw members 2 and 3 changing from an open mouth state to a closed mouth state, the multiple tooth members 5 installed on the jaw member 2 all become the rotation position for tooth decay.

[0064] Next, the method of using toy 1 will be explained.

[0065] First, regarding Figure 1 and Figure 2 In the case of toy 1 with its mouth closed, the user of toy 1 pulls rod 6 forward (lays it down), causing jaw components 2 and 3 of toy 1 to... Figure 3 That puts the mouth in an open position. With the mouth open, the user of toy 1 can see the multiple toothed components 5 installed on the jaw component 2.

[0066] When jaw components 2 and 3 are in a closed mouth state ( Figure 1 and Figure 2 When the state of the mouth is open, the multiple tooth components 5 installed on the jaw component 2 all become the rotation position of the tooth, that is, as Figure 3 As shown, the upper surfaces of the multiple tooth members 5 installed on the jaw member 2 all become surfaces 5a that mimic caries. That is, in this stage, the multiple tooth members 5 installed on the jaw member 2 are in a state where the surfaces 5a that mimic caries are exposed from the jaw member 2. Therefore, in this stage, when the user of the toy 1 observes, the multiple tooth members 5 installed on the jaw member 2 are all seen as caries.

[0067] Next, the user of toy 1 removes the toothbrush-like component 11 from the support base 4 and presses it onto the tooth component 5. By applying rotational force to the tooth component 5 using the component 11, the tooth component 5 rotates. As a result, the tooth component 5 in the position of rotating as a tooth decayed tooth (i.e., the tooth component 5 with the tooth decayed tooth surface 5a as its upper surface) rotates, and the tooth component 5 in the position of rotating as a non-tooth decayed tooth (i.e., the upper surface of the tooth component 5 becomes the tooth surface 5b of a non-tooth decayed tooth). Thus, when the user of toy 1 observes, they see the tooth component 5 in the position of rotating as a tooth decayed tooth (the tooth component 5 in the position of rotating as a tooth decayed tooth) rotating due to the operation generated by the toothbrush-like component 11, making it appear as if the tooth decay has been cured and transformed into a non-tooth decayed tooth (the tooth component 5 in the position of rotating as a non-tooth decayed tooth).

[0068] exist Figure 4The image shows a state where a component 11, mimicking a toothbrush, causes all the tooth components 5 mounted on the jaw component 2 to change from a tooth-like rotational position to a non-tooth-like rotational position. That is, as shown... Figure 3 As shown, the entire tooth component 5 is exposed from the palatal component 2 by rotating the tooth component 5 using a component 11 that mimics a toothbrush, thus, as Figure 4 As shown, all the tooth components 5 are transformed to mimic the state in which the surface 5b of a non-caries tooth is exposed from the jaw component 2.

[0069] The user of toy 1 can use the toothbrush-like component 11 to rotate any one of the multiple tooth components 5 installed on the jaw member 2, thereby changing the tooth component 5 located in the tooth-cavitating rotation position to a non-tooth-cavitating rotation position. For example, it is also possible to change all of the multiple tooth components 5 installed on the jaw member 2 from the tooth-cavitating rotation position to a non-tooth-cavitating rotation position, or it is also possible to change a portion of the multiple tooth components 5 installed on the jaw member 2 from the tooth-cavitating rotation position to a non-tooth-cavitating rotation position, while keeping the remaining portion in the tooth-cavitating rotation position.

[0070] By using the toothbrush-like component 11 to rotate the tooth component 5, the tooth component 5, which is located in the rotation position of a carious tooth, is changed to a rotation position of a non-carious tooth. This behavior makes the user of the toy 1 associate with the behavior of brushing teeth, and makes the user of the toy 1 realize that brushing teeth is effective in eliminating (reducing) cavities.

[0071] Furthermore, instead of the toothbrush-imitating component 11, the tooth component 5 can be rotated using the dental tool-imitating component 12, thereby changing the tooth component 5 from a position associated with tooth decay to a non-tooth decay position. By rotating the tooth component 5 using the dental tool-imitating component 12, thus changing it from a position associated with tooth decay to a non-tooth decay position, the user of toy 1 is reminded of the act of treating tooth decay using dental tools. This allows the user of toy 1 to realize that treating tooth decay at a dental clinic or similar facility is effective in eliminating (reducing) tooth decay.

[0072] Next, the user of toy 1 moves lever 6 inward (erects it), thereby causing jaw member 3 to move relative to jaw member 2, and jaw member 2 and jaw member 3 to move from an open mouth state ( Figure 4 (to become a closed-mouth state) Figure 1 and Figure 2 With the mouth closed, the user of toy 1 cannot see the multiple toothed components 5 installed on the jaw component 2.

[0073] At this point, as described above Figure 10 and Figure 11As explained, when the jaw members 2 and 3 are in the open mouth state, regardless of whether each tooth member of the multiple tooth members 5 of the toy 1 is in the tooth rotation position or the non-tooth rotation position, corresponding to the change of the jaw members 2 and 3 from the open mouth state to the closed mouth state, the multiple tooth members 5 of the toy 1 are all in the tooth rotation position.

[0074] In other words, even when jaw members 2 and 3 are in an open mouth state, the tooth member 5, which is in a tooth-causing rotation position, is changed to a non-tooth-causing rotation position by the toothbrush-mimicking member 11. This non-tooth-causing rotation position of the tooth member 5 will also correspond to the tooth-causing rotation position corresponding to the change of jaw members 2 and 3 from an open mouth state to a closed mouth state. On the other hand, the tooth member 5, which is designed to maintain the tooth-causing rotation position when jaw members 2 and 3 are in an open mouth state, will maintain the tooth-causing rotation position even when jaw members 2 and 3 change from an open mouth state to a closed mouth state.

[0075] Next, the user of toy 1 pulls rod 6 forward (lays it down), causing jaw member 3 to move relative to jaw member 2, and jaw members 2 and 3 to close their mouths. Figure 1 and Figure 2 ) becomes an open mouth state ( Figure 3 With the mouth open, the user of toy 1 can see multiple tooth components 5 installed on the jaw member 2. At this time, the multiple tooth components 5 installed on the jaw member 2 are all in the rotation position of a tooth (that is, the surface 5a that imitates a tooth becomes the rotation position of the upper surface of the tooth component 5). Therefore, when the user of toy 1 observes, the multiple tooth components 5 installed on the jaw member 2 are all seen as teeth.

[0076] Then, the user of toy 1 can repeat the above operation. That is, by using the toothbrush-like component 11 to rotate the tooth component 5, the user of toy 1 can change the tooth component 5 from the rotation position of the tooth with cavities to the rotation position of the non-cavities. Then, by retracting the lever 6 inward, the jaw components 2 and 3 change from an open mouth state to a closed mouth state, and at the same time, the multiple tooth components 5 installed on the jaw component 2 are all in the rotation position of the tooth with cavities. Then, by tilting the lever 6 forward, the jaw components 2 and 3 change from a closed mouth state to an open mouth state, but in this state, the tooth components 5 visible to the user of toy 1 are all in the rotation position of the tooth with cavities.

[0077] The toy 1 of this embodiment includes a jaw member 2 that mimics a jaw and multiple tooth members 5 that are mounted on the jaw member 2 and each mimics a tooth. The multiple tooth members 5 of the toy 1 are each mounted with a predetermined surface exposed from the jaw member 2. The multiple tooth members 5 of the toy 1 can be changed in response to the user's operation to a state where surface 5a of the tooth member 5 is exposed from the jaw member 2 and a state where surface 5b of the tooth member 5 is exposed from the jaw member 2, thereby increasing the fun of the toy 1.

[0078] Furthermore, in each of the multiple tooth components of toy 1, surface 5a imitates a decayed tooth, and surface 5b imitates a non-decayed tooth. Therefore, the act of changing the state of surface 5a of tooth component 5 from being exposed to the jaw member 2 to the state of surface 5b of tooth component 5 being exposed to the jaw member 2 is easily associated with the act of changing a decayed tooth into a non-decayed tooth, thus further enhancing the fun of toy 1. Additionally, when the appearance of a decayed tooth is represented by printing or labeling on the outer component (shell component) 22, pressing (rubbing) the components 11 and 12 on the tooth component 5 may cause damage such as ink peeling or label peeling. However, in toy 1, each tooth component 5 has an inner component 23 separately provided as an appearance component representing a decayed tooth, thus preventing such damage and protecting the aesthetics of toy 1.

[0079] In addition, toy 1 includes a rotating operating component operated by the user of toy 1. This component rotates each of the multiple toothed components 5 by pressing on them. The rotating operating component mimics a toothbrush or dental tool. Therefore, the user of toy 1 can easily associate it with brushing teeth or treating cavities while playing with toy 1. This further enhances the fun of toy 1.

[0080] Furthermore, the toy 1 of this embodiment includes a jaw member 2 that mimics the lower jaw and a jaw member 3 that mimics the upper jaw. When the jaw members 2 and 3 are in an open mouth state, the plurality of tooth members 5 provided by the toy 1 can respectively change to a state in which the surface 5a of the tooth member 5 is exposed from the jaw member 2 and a state in which the surface 5b of the tooth member 5 is exposed from the jaw member 2, corresponding to the operation of the user of the toy 1. Moreover, corresponding to the jaw members 2 and 3 changing from an open mouth state to a closed mouth state, the plurality of tooth members 5 provided by the toy 1 are all in a state in which the surface 5a of the tooth member 5 is exposed from the jaw member 2. Thus, as long as the mouth is opened and closed, repeated play using the toy 1 can be performed, thereby improving the operability of the toy 1. In addition, the fun of the toy 1 can be further enhanced.

[0081] The invention made by the inventor has been specifically described above based on its implementation method, but the invention is not limited to the described implementation method, and it goes without saying that various modifications can be made without departing from its spirit.
