[0002] [Patent Document 1] Utility Model Registration No. 3191973 Summary of the Invention [Problem to be solved by the invention]

[0003] In the above-mentioned moving toy, the sun gear and planetary gears that make up the planetary gear mechanism are mounted on the same member (body), and the rotation of the sun gear in one direction moves a moving body connected to one reduction gear train, and the rotation of the sun gear in the other direction moves a moving body connected to another reduction gear train. Also known as moving toys are those that are provided with a timer mechanism and operate a plurality of moving bodies at different times. However, although both can operate multiple moving objects with a time difference, the former moving toy requires a motor to rotate forward and backward, and the latter moving toy requires a timer mechanism, making both complex. An object of the present invention is to provide a moving toy with a simple structure that can move two moving bodies with a time lag. [Means for solving the problem]

[0006] The third means is the second means, and when the first operation of the second operating body is completed and the rotation of the planetary gears is stopped, the rotation of the sun gear causes the planetary gears to revolve from the first revolution position to the second revolution position against the biasing force of the elastic body, thereby oscillating the first operating body in the rotation direction of the sun gear. It is characterized by:

[0007] The fourth means is the third means, characterized in that the operating device returns the planetary gear to the first orbital position by the biasing force of the elastic body when the rotation of the sun gear stops at the second orbital position.

[0008] The fifth means is the fourth means, The operating device includes a motor that can rotate forward and backward, The operating device is At a first revolution position where the revolution of the planetary gear is prevented by the elastic body, the planetary gear rotates on its axis due to the reverse rotation of the sun gear, causing the second moving body to perform a second movement, When the second operation of the second operating body is completed and the rotation of the planetary gear stops, the rotation of the sun gear causes the planetary gear to revolve from the first revolution position to the third revolution position against the biasing force of the elastic body, thereby oscillating the first operating body in the reverse direction of the sun gear. It is characterized by:

[0009] The sixth means is the fifth means, The operating device is characterized in that, when the rotation of the sun gear stops at the third revolution position, the biasing force of the elastic body returns the planetary gear to the first revolution position.

[0015] Hereinafter, a moving toy according to an embodiment of the present invention will be described with reference to the drawings.

[0016] FIG. 1 is a perspective view showing an action toy 100 according to an embodiment, and FIG. 2 is a front view of the action toy 100. As shown in FIG. The moving toy 100 comprises a base 10 and a doll body 20 provided on the base 10.

[0017] The base 10 is an octagonal prism-shaped stage. An A button 11 and a B button 12 are provided on the top surface of the base 10. The A button 11 and the B button 12 serve as a power button and a mode switching button, which will be described in detail later.

[0018] The doll body 20 is an animal doll that stands on two legs. An example of the movement of the doll body 20 will be explained as follows. In the following explanation, "left," "right," "front," "back," "up," and "down" refer to "left," "right," "front," "back," "up," and "down" as seen from the doll body 20. From the basic posture (Fig. 2), the left arm 23L is raised and the right arm 23R is lowered at the same time. At this time, the head 24 also moves slightly to the right (Fig. 9). By moving the head 24 slightly to the right, interference with the head 24 is prevented when the left arm 23L is raised, allowing for greater movement of the left arm 23L. Furthermore, because the shape of the torso 22 is flat, interference with the abdomen is prevented when the right arm 23R is lowered, allowing for greater movement of the right arm 23R. Next, the left and right arms 23L, 23R and head 24 are left in the same positions relative to the torso 22, and the torso 22 is tilted to the right (FIG. 10). After that, the torso 22, the left and right arms 23L, 23R and head 24 of the doll body 20 are returned to the basic position (FIG. 2). Thereafter, from the basic posture (FIG. 2), the right arm 23R is raised and the left arm 23L is lowered at the same time. At this time, the head 24 also moves slightly to the left (FIG. 11). By moving the head 24 slightly to the left, interference with the head 24 is prevented when the right arm 23R is raised, allowing the right arm 23R to move more widely. Furthermore, because the shape of the torso 22 is flat, interference with the abdomen is prevented when the left arm 23L is lowered, allowing the left arm 23L to move more widely, all the way up to the front of the abdomen. Next, the left and right arms 23L, 23R and head 24 are left in the same positions relative to the torso 22, and the torso 22 is tilted to the left (FIG. 12). After that, the torso 22, the left and right arms 23L, 23R and head 24 of the doll body 20 are returned to the basic position (FIG. 2). Thereafter, the doll body 20 repeats the above-mentioned movements.

[0019] (20 dolls) FIG. 3 is a front view of the doll body 20 showing the internal structure of the doll body 20. The doll body 20 comprises left and right legs 21L, 21R, a torso 22, left and right arms 23L, 23R, and a head 24. The left and right legs 21L, 21R are fixed to the base 10 in a spread-legged state. The left and right legs 21L, 21R are connected to each other via a connecting part 25 inside the body 22. A shaft 26 extending in the front-to-rear direction is attached to this connecting part 25. The body 22 is connected to the connecting part 25 via the shaft 26. This allows the body 22 to swing left and right within a predetermined range around the shaft 26.

[0020] The head 24 is integrally formed with the neck 27 and the left and right shoulders 28L, 28R. The lower end of a link 29 is connected to the body 22 via a shaft 29a extending in the front-to-rear direction. This allows the link 29 to rotate within a predetermined range around the shaft 29a. The upper end of the link 29 is connected to the lower end of the neck 27, which is integral with the head 24, via a shaft 30. The rear end of the shaft 30 is inserted into a groove 30a (Fig. 3), which restricts the rotation range of the link 29. This allows the head 24 to swing left and right within a predetermined range when the link 29 rotates left and right around the shaft 29a.

[0021] Next, the left and right arms 23L, 23R will be described. Note that since the left and right arms 23L, 23R have a symmetrical structure, only the structure of the left arm 23L will be described, and a description of the structure of the right arm 23R will be omitted. FIG. 4 is a perspective view of the left arm 23L as seen from behind. The base of the arm 23L is bent downward within the torso 22, and the lower end of the bent part is connected to the torso 22 via an axis 31, and the upper end of the bent part is connected to the shoulder 28L via an axis 32.

[0022] The arm 23L includes an upper arm 230, a lower arm 231, and a hand 232. The upper arm 230 is made up of a front upper arm part 230F and a rear upper arm part 230R. The front upper arm part 230F is connected to the torso 22 via a shaft 31. The rear upper arm part 230R is connected to the shoulder 28L via a shaft 32.

[0023] Further, the lower arm portion 231 is connected to the front upper arm part 230F via a pin 33, and is connected to the rear upper arm part 230R via a pin 34. Further, a hand portion 232 is attached to the lower cup portion 231 by recess-and-projection fitting. This allows the front upper arm part 230F and the rear upper arm part 230R to move relatively and separately.

[0024] (Operating device 40) FIG. 5 is a front perspective view showing part of the operating device, FIG. 6 is a front view of the doll body with part of the operating device exposed, and FIG. 7 is a rear view of the doll body with part of the operating device exposed. An electric operating device 40 is provided inside the base 10 and the doll body 20 to operate the head 24, the left and right arms 23L, 23R, and the torso 22. A dry battery (not shown) is used as the power source for this operating device 40. The dry battery is detachably provided inside the base 10.

[0025] The operating device 40 includes a motor 41 that can rotate forward and backward as a power source. The power of the motor 41 is transmitted to the link 29 via gears 42a to 42j.

[0026] Of these, gears 42a to 42e are provided inside base 10. Gear 42a is a motor gear, and gear 42b is a crown gear that meshes with motor gear 42a. Gear 42c is a gear that is provided coaxially with gear 42b and rotates integrally with gear 42b. Gear 42d is a gear that is provided on a different axis from gear 42c and meshes with gear 42c, and gear 42e is a gear that is provided on a different axis from gear 42d and meshes with gear 42c.

[0027] Gears 42f to 42j are provided inside the doll body 20. Gear 42f is provided on the same shaft 43 as gear 42d and rotates integrally with gear 42d. Shaft 43 passes through the left leg 21L of the doll body 20. Gear 42g is a crown gear provided on shaft 26 of connecting portion 25 and meshes with gear 42f. Gear 42h is a gear (sun gear) provided coaxially with gear 42g and rotates integrally with gear 42g. Gear 42i is a gear (planetary gear) meshing with gear 42g. Gear 42i is fixed in position relative to the body 22 by, for example, having its shaft fixed to or integrally molded with the body 22. Gear 42j is a gear meshing with gear 42i, and is attached to shaft 29a and moves integrally with link 29.

[0028] Additionally, a cylindrical protrusion 44 is provided on the rear surface of the connecting portion 25 that supports the shaft 26, behind the rear side of the gear 42g. A torsion spring 45 is wound around the cylindrical protrusion 44. A stopper 46 extending in the left-right direction is provided below the cylindrical protrusion 44. Ends 45L, 45R of the torsion spring 45 extend below the stopper 46. The end portions 45L, 45R face each other with the central stopper 46 in between. Furthermore, two ribs 47L, 47R extending in the vertical direction are provided inside the rear torso part that constitutes torso 22, and the two ribs 47L, 47R are located between ends 45L, 45R of torsion spring 45. This limits the oscillation of torso 22 about axis 26. In other words, the revolution of gear (planetary gear) 42i around gear (sun gear) 42h is limited.

[0029] (20 doll body movements) The doll body 20 configured as above can move as follows: Here, the revolution position of the gear 42i in the basic posture of Fig. 2 is defined as a first revolution position. When the planetary gear 42i is in the first revolution position, the inner ribs 47L, 47R of the rear torso part 22R are positioned between the ends 45L, 45R of the torso spring 45. In this state, the torso 22 is prevented from swinging left and right relative to the left and right legs 21L, 21R by the torsion spring 45. As a result, when the gear (sun gear) 42h is rotated by the motor 41 in this state, the meshing gear 42i rotates (spins) on the spot in a direction corresponding to the rotation direction of the gear 42h, and the rotational power of the gear 42j rotates in a predetermined direction, and the left and right arms 23L, 23R and head 24 move in a predetermined direction via the left and right shoulders 28L, 28R. Then, when the shaft 30 at the upper end of the link 29 reaches the end of the groove 30a, the rotation of the link 29 and therefore the gear 42j stops. The state after this operation is shown in Figures 9 and 11. It should be noted that even during movement of the left and right shoulders 28L, 28R, the torso 22 may be subjected to a rotational torque via the front upper arm part 230F and the axis 31 due to the movement of the rear upper arm part 230R, but in this case, the biasing force of the torsion spring 45 is strong, and the revolution described below does not occur solely due to the rotational torque.

[0030] When the movement of the left and right arms 23L, 23R and the head 24 ends and the rotation of the gear 42j linked thereto is also stopped, the continued rotation of gear 42h causes gear 42i to revolve around gear 42h in the same direction as the rotation of gear 42h against the biasing force of torsion spring 45. This means that the timing at which the revolution starts (the timing at which the trunk 22 swings) can be easily adjusted by setting the range of groove 30a. Note that the revolution position of gear 42i in this case differs depending on the rotation direction of gear 42h, and therefore will hereinafter be collectively referred to as "other revolution positions." As a result, the torso 22 swings relative to the left and right legs 21L, 21R and assumes a tilted posture. The state after this movement is shown in Figures 10 and 12. Figure 8 is a rear view showing the state of the torsion spring 45 of the doll body 20 at this time.

[0031] Furthermore, when the rotation of the motor 41 stops and the rotation of the gear (sun gear) 42h stops at another revolution position, the torso 22 tries to return to an upright position relative to the left and right legs 21L, 21R due to the biasing force of the torsion spring 45. This causes the gear 42h to revolve around its axis and return to the first revolution position.

[0032] (Control Configuration) FIG. 13 is a block diagram showing the functional configuration of the moving toy 100. As shown in FIG. The moving toy 100 includes, as functional components, a detection unit 50, a mode input unit 51, a microphone 52, a control unit 53, a memory unit 54, a communication unit 55, and a light emitting unit 56.

[0033] The detection unit 50 includes a detector switch (not shown) disposed on the connecting portion 25 . The detector switch detects whether or not the torso 22 is in an upright position relative to the left and right legs 21L, 21R, and sends a detection signal to the control unit 53. For example, when the control unit 53 determines based on the detection signal that the torso 22 is not in the upright position, it controls the motor 41 to bring the torso 22 into an upright state.

[0034] The mode input unit 51 includes push button switches (not shown) corresponding to the A button 11 and the B button 12. The push button switches detect the selected mode and send a detection signal to the control unit 53. The control unit 53 executes the mode based on the detection signal.

[0035] The control unit 53 is configured to include a microcontroller unit and peripheral circuits, and reads out each program from the storage unit 54 and executes processing and control in accordance with each program.

[0036] The storage unit 54 is equipped with a storage device such as a flash memory that can write and read data, and stores operating programs and data necessary for executing the programs.

[0037] The communication unit 55 includes an LED for transmission and a photodiode or CMOS for reception. This communication unit 55 communicates with the adjacent moving toy 100 under the control of the control unit 53, and based on this, the control unit 53 synchronizes and operates the moving toys 100.

[0038] The light emitting unit 56 includes LEDs (not shown) attached to the left and right arms 23L and 23R. The light emitting unit 56 blinks the LEDs under the control of the control unit 53, causing the tips of the hands 232 to blink.

[0039] (Switch specifications) FIG. 14 shows the specifications of the switch of the moving toy 100. Pressing the A button 11 or B button 12 will put the device into microphone mode, and briefly pressing both the A button 11 and the B button 12 will put the device into program mode. To turn the device off, press and hold both the A button 11 and the B button 12 simultaneously. After entering microphone mode, each time the B button 12 is pressed, the mode transitions in the following order: communication mode, flashing mode, microphone mode, etc. Also, after entering microphone mode, if the A button 11 and the B button 12 are pressed briefly, the mode transitions to program mode.

[0040] A. Microphone mode In the microphone mode, the doll body 20 operates when an external sound is picked up by the microphone, and goes into standby mode when the external sound has ceased for a predetermined period of time.

[0041] B. Communication Mode In the communication mode, the moving toys 100 communicate with each other, and adjacent moving toys 100 are synchronized and operated.

[0042] C. Flashing Mode In the blinking mode, it blinks the LED of the hand part 232. If a colored transparent member is attached to the hand part 232, the light-transmitting member can be made to blink in that color.

[0043] D. Program Mode The moving toy 100 is made to move according to a program, and the moving toy 100 is made to move according to a program that is pre-installed.

[0044] (Variation) Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications are possible.

[0045] For example, in the above embodiment, the torso 22 starts to swing when the planetary gear 42i starts to revolve, but because the torso 22 receives a rotational torque via the front upper arm part 230F and the shaft 31 in response to the movement of the rear upper arm part 230R, it is also possible to delay the swing of the torso 22 using only the rotational torque by adjusting the biasing force of the torsion spring 45. In this case, in the embodiment, the timing of the swing of the torso 22 can be adjusted by adjusting the biasing force of the torsion spring 45.

[0046] In the above embodiment, the body is tilted to the left or right after the left and right arms are moved up and down, but the present invention can be applied to general moving toys in which a second moving body provided on a first moving body is moved, and then the first moving body is moved. For example, the present invention can be applied to a case in which the tail of an animal toy is made up of two members, and the tip member is moved, and then the base member is moved.

[0047] Furthermore, in the above embodiment, one example of the movement of the doll body 20 has been described, but the rotation direction of the motor may be changed at a position different from the above (in the middle of rotation or revolution). [Explanation of symbols]
