[0019] Hereinafter, a toy according to an embodiment of the present invention will be described with reference to the drawings.

[0020] Appearance and Operation Figure 1 is a perspective view of a doll toy 1 according to an embodiment. In this description of the doll toy 1, "up and down" and "left and right" refer to the directions shown in Figure 1, "front" refers to the front side of the doll toy 1, and "back" refers to the rear side of the doll toy 1. This doll toy 1 is, for example, a stuffed bear. When this doll toy 1 is lifted with both hands and the abdomen is repeatedly pressed with the thumbs, and then the thumbs are released from the abdomen, the eyeballs 10 move from side to side many times, and the eyelids 11 move up and down repeatedly to open and close.

[0021] 《Operation Unit 20》 Figure 2 is a perspective view showing the external appearance of the operating unit 20, Figure 3 is a perspective view showing the operating unit 20 with the front frame 21a removed, and Figure 4 is a side view showing the functional configuration of the operating unit 20. The doll toy 1 has an internal operating unit 20. The functional components of the operating unit 20 are assembled in a single housing 21. A transparent plastic front frame 21a is provided on the upper front part of the housing 21. The operating unit 20 includes an eyeball 10 and an eyelid 11, a power generating unit 30 that generates power to move the eyeball 10 and the eyelid 11, and a power transmission mechanism 40 that transmits the power generated by the power generating unit 30 to the eyeball 10 and the eyelid 11.

[0022] 《Eyeball 10 and eyelid 11》 Figure 5 is a perspective view showing the eyelid 11 and the eyelid movement mechanism, and Figure 6 is a perspective view showing the eyeball 10 and the eyeball movement mechanism. Each of the left and right eyelids 11 is composed of an arched or curved plate and is connected to each other by a connecting shaft 11a. Each of the left and right eyelids 11 is mounted on the housing 21 so as to be rotatable vertically within a predetermined angular range around a second axis 11b, which is the horizontal axis. Furthermore, the left and right eyelids 11 are made of, for example, transparent plastic, so that the eyeball 10 located inside them can be seen even when the eyelids 11 are closed. Each of the left and right eyeballs 10 is hemispherical in shape, with a pupil drawn on its surface. Each of the left and right eyeballs 10 is partially covered by the left and right eyelids 11. The left and right eyeballs 10 are also mounted on the housing 21 separately so as to be rotatable left and right within a predetermined angular range around a first axis 10a, which is the vertical axis.

[0023] Power generation unit 30 As shown in Figure 4, the power generation unit 30 includes a mainspring unit 31 and a mainspring winding mechanism 32 for winding the mainspring.

[0024] <Spring Unit 31> Figure 7 is a side view showing the mainspring unit 31 and its surroundings. The mainspring unit 31 is equipped with a mainspring and a speed governor (not shown) within a housing 31a. The housing 31a is provided with a core body (winding shaft) 31b that penetrates in the front-to-back direction. An input shaft 31c for inputting winding power and an output shaft 31d for extracting slack force are fixedly mounted on this core body 31b. As a result, the input shaft 31c and the output shaft 31d rotate in conjunction with each other.

[0025] <Mainspring winding mechanism 32> Figure 8 is a perspective view showing the mainspring unit 31 and the mainspring winding mechanism 32. A. Push button 33 The mainspring winding mechanism 32 is configured to include a push button 33, as shown in Figures 3 and 8. The push button 33 is constructed in a hollow cylindrical shape, with one end closed and the other end open. The push button 33 is mounted on the housing 21 such that the closed end is at the front and the open end is at the rear. The push button 33 is fitted from the front into the cylindrical portion 22 of the lower half of the housing 21. Grooves 33a are formed on the left and right sides of the outer circumferential surface of the push button 33, along the generatrix. The grooves 33a engage with the protrusions 22a attached to the cylindrical portion 22 of the housing 21, allowing the push button 33 to move in the front-rear direction within a predetermined range relative to the cylindrical portion 22. The push button 33 is biased forward by the biasing force of a coil spring 33b interposed between it and the housing 21.

[0026] B. Motion conversion mechanism 34 As shown in Figure 8, the mainspring winding mechanism 32 includes a motion conversion mechanism 34 that converts the linear motion of the push button 33 into the rotational motion of the mainspring's input shaft 31c.

[0027] In other words, the rear of the push button 33 has two parallel protruding pieces 34a extending diagonally upward and backward. A pin 34b is placed between the tips of these two protruding pieces 34a. Two protruding pieces 34a, and near the tips of 34a, a rotating body 35 that can rotate around an axis 35a extending in the left-right direction is attached to the housing 21.

[0028] Figure 9 is an enlarged perspective view showing the rotating body 35. The rotating body 35 consists of a rotating part 351 with a bifurcated portion 350 formed at an eccentric position from the shaft 35a, a rotating part 353 with a missing-tooth crown gear 352 formed thereon, and a coil spring (tension spring) 354 with one end attached to the rotating part 351 and the other end attached to the rotating part 353, connecting the rotating part 351 and the rotating part 353. The bifurcated portion 350 of the rotating portion 351 engages with the pin 34b, and the toothless crown gear 352 of the rotating portion 353 meshes with the gear 310 formed on the input shaft 31c. The input shaft 31c is mounted on the core body 31b so as to be able to rotate freely. A one-way clutch (not shown) is interposed between the gear 310 and the core body 31b, and connects the input shaft 31c and the core body 31b only when the push button 33 is pressed.

[0029] Power transmission mechanism 40 Returning to Figure 7, the power transmission mechanism 40 is composed of an output shaft 31d, a one-way clutch 40a, and a transmission shaft 40b. The clutch pieces of the one-way clutch 40a are in contact with each other by the biasing force of a coil spring 40c that biases the transmission shaft 40b toward the output shaft 31d. The one-way clutch 40a releases the connection between the output shaft (driving shaft) 31d and the transmission shaft (driven shaft) 40b when the output shaft (driving shaft) 31d rotates in the opposite direction during winding of the mainspring. On the other hand, the power transmission mechanism 40 connects the output shaft 31d and the transmission shaft 40b when the output shaft 31d rotates in one direction during unwinding of the mainspring.

[0030] <Eye movement mechanism> The power transmission mechanism 40 includes an eyeball motion mechanism that moves the eyeball 10 by the rotation of the output shaft 31d. As shown in Figure 6, the eyeball motion mechanism comprises a cam mechanism (first cam mechanism) 41 and a motion conversion mechanism (first motion conversion mechanism) 42.

[0031] A. Cam mechanism 41 The cam mechanism 41 is composed of a plate cam. The cam (original segment) 41a is fixed to the output shaft 31d. A portion of the eyeball operating member (following segment) 41b, which is movable left and right, is in contact with the cam 41a by the biasing force of the coil spring 41c.

[0032] B. Motion conversion mechanism 42 The motion conversion mechanism 42 converts the left-right movement of the eyeball manipulation member 41b into rotational movement of the eyeball 10. Specifically, the eyeball manipulation member 41b has an elongated notch 42a in the front-to-back direction, while the second axis 11b of the eyeball 10 is provided with an eccentric pin 42b that engages with the notch 42a. As a result, when the eyeball manipulation member 41b moves left-to-right, the eyeball 10 rotates left-to-right around the second axis 11b.

[0033] <Eyelid movement mechanism> The power transmission mechanism 40 includes an eyelid movement mechanism that moves the eyelid 11. Figure 10 is a perspective view showing the eyelid movement mechanism, which comprises a cam mechanism (second cam mechanism) 45 and a motion conversion mechanism (second motion conversion mechanism) 46. A. Cam mechanism 45 The cam mechanism 45 is composed of a plate cam. The cam (original section) 45a is fixed to the transmission shaft 40b. The lower end of the eyelid operating member (following section) 45b, which is movable up and down, is in contact with the cam 45a by the biasing force of the coil spring 45c.

[0034] B. Motion conversion mechanism 46 The motion conversion mechanism 46 converts the vertical movement of the eyelid operating member 45b into rotational movement of the eyelid 11. Specifically, a pin 46a is provided on one side of the eyelid operating member 45b, while a bifurcated portion 46b that engages with the pin 46a is attached to the connecting shaft 11a of the eyelid 11 at an eccentric position. As a result, when the eyelid operating member 45b moves up and down, the eyelid 11 moves up and down, opening and closing.

[0035] Sound output mechanism The doll toy 1 is equipped with a sound-producing mechanism. The sound-producing mechanism is equipped with a bellows 60 that allows air to enter and exit. The bellows 60 is located in the hollow part of the push button 33 and contracts when the push button 33 is pressed, and expands due to the restoring force when the pressure is released. At this time, air is drawn in and sound is emitted. This sound is emitted to the outside through the sound-emitting hole 33c (see Figure 8) of the push button 33.

[0036] 《Operation》 Hold the doll toy 1 with both hands. Repeatedly press the abdomen with both thumbs. This winds up the mainspring. At this time, the one-way clutch 40a is given rotation in the opposite direction, so the position of the eyeball 10 can be displaced relative to the position of the eyelid 11. Then, when the pressure on the abdomen is released, the one-way clutch 40a is given one-way rotation, the output shaft 31d and the transmission shaft 40b are coupled, and the eyeball 10 and eyelid 11 begin to move from their new relative positions.

[0037] Effects of the Embodiment According to this doll toy 1, the following effects can be obtained. When the mainspring is wound, only the eyeball 10 moves, causing the initial position of the eyeball 10 when relaxed to shift. The amount of this shift varies depending on the number of times and the degree of pressure applied to the push button 33. Therefore, the initial position (relative position) of the eyeball 10 and eyelid 11 when relaxed changes randomly each time.

[0038] Furthermore, since the eyeball movement mechanism and eyelid movement mechanism include cam mechanisms 41 and 45, the dependent segments move in accordance with the shape of the cam (primary segment), allowing for fine and delicate movements of the eyeball 10 and eyelid 11.

[0039] Furthermore, since the rotational motion is converted into linear motion by the cam mechanisms 41 and 45, and then the linear motion is converted back into rotational motion by the motion conversion mechanisms 42 and 46, the change in the outer diameter of the cams 41a and 45a can be converted into reciprocating motion and velocity changes of the eyeball 10 and eyelid 11, thus allowing for fine changes in the movement of the eyeball 10 and eyelid 11.

[0040] Variant form Although embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible without changing the gist of the present invention.

[0041] In the above embodiment, the position of the eyeball 10 was displaced relative to the position of the eyelid 11 by applying reverse rotation to the one-way clutch 40a when winding the mainspring, but the position of the eyelid 11 may also be displaced relative to the position of the eyeball 10.

[0042] Furthermore, although a spring was used as the power source in the above embodiment, a forward / reverse motor may also be used as the power source. In this case, it is preferable to regularly or randomly displace the relative position of one of the eyeball 10 and eyelid 11 with respect to the other position by controlling the forward / reverse rotation of the motor before the movement of the eyeball 10 and eyelid 11.

[0043] Furthermore, in the above embodiment, operating members are provided on the driving shaft (output shaft 31d) and the driven shaft (transmission shaft 40b), which can be coupled and uncoupled by the one-way clutch 40a. However, operating members may also be provided on the shaft linked to the driving shaft and / or the driven shaft.

[0044] Furthermore, although the moving members in the above embodiment were the eyeball 10 and eyelid 11, the two operating members are not limited to the eyeball 10 and eyelid 11 as long as the movement of the two moving members can be seen simultaneously, and the invention can be applied to toys in general. For example, in the case of a doll toy, the two members may be both hands, hands and feet, or head and hands. It may also be a toy other than a doll toy.

[0045] Furthermore, in the above embodiment, cam mechanisms 41 and 45 are provided on the driving shaft (output shaft 31d) and the driven shaft (transmission shaft) 40b, which can be coupled and uncoupled by a one-way clutch 40a, to operate the eyeball 10 and eyelid 11. However, at least one of the driving shaft (output shaft 31d) and the driven shaft (transmission shaft) 40b can be replaced with other mechanisms, such as a gear mechanism or a link mechanism.
