  The best mode of the walking toy according to the present invention is a water-absorbing sheet 100 that is a laminated sheet with a waterproof sea back surface, a water pen 110 that can draw a line drawing on the water-absorbing sheet 100 with water, and a walking toy that includes a motor 35. It is a walking toy set that combines.

  The walking toy is a toy that can be moved to imitate a character having at least a head 13, a trunk 11, and a leg 17, and includes a motor 35 and forward and reverse rotations of the motor 35. A gear box 50 is built in which either the right drive wheel 73 or the left drive wheel 77 is rotated forward based on the rotation direction to be rotated, and a center electrode 83 that is grounded on the traveling surface and the traveling surface that surrounds the central electrode 83 And a control unit 41 that switches between forward and reverse rotation directions of the motor 35 when the detector 81 detects a wet location on the running surface. It is a walking toy that moves forward by alternately driving the right driving wheel 73 and the left driving wheel 77 by switching the forward rotation and reverse rotation of the motor 35 by the control unit 41.

  Then, when the wet position cannot be detected by the detector 81 during the forward rotation of the right drive wheel 73 or the left drive wheel 77, the control unit 41 turns the toy main body 10 by about one rotation with one drive wheel. After this, the motor 35 is controlled to rotate forward and backward so that the other drive wheel rotates forward and the toy body 10 rotates about once in the opposite direction.

  The walking toy according to the present invention is a toy imitating the shape of a doll such as a character as shown in FIGS. 1 and 2, and has a head 13, a trunk 11, an arm 15, and a leg 17. is.

  Further, the lower end of the leg portion 17 has a leg bottom surface 19 that is a flat surface that can stably stand the toy. As shown in FIG. It has a detector 81, and has a right drive wheel 73 and a left drive wheel 77 on the left and right of the leg bottom surface 19.

  The toy body 10 as the head 13, body 11 and legs 17 of the walking toy is formed by a front case 21 and a rear case 23 as shown in FIG. The speaker 37 is fixed inside 11.

  Further, a battery cover 25 is formed to be detachable from the head 13 of the rear case 23 to the body 11, and a power switch 33 is slightly protruded from the head 13 on the rear side of the head 13 in the rear case 23. In this way, the switch box 31 is mounted inside the head 13.

  The rear case 23 is formed with a battery storage portion 27 for storing the battery 29 inside the bar, and a control box 40 is attached to the inside of the toy main body of the battery storage portion 27.

  A gear box 50 to which the motor 35 is fixed is fixed to the leg bottom surface 19 of the toy main body 10, and the right driving wheel 73 and the left driving wheel are arranged at the distal ends of the rotating shafts protruding left and right from near the lower end of the gear box 50. 77 is provided, and a part of the right driving wheel 73 and the left driving wheel 77 is projected from the bottom surface 19 of the leg.

  In addition, a detector 81 is provided on the lower surface of the front end of the detector support arm 91 projecting forward from the lower end of the gear box 50, and the lower end of the detector 81 is projected from the leg bottom surface 19.

  Note that the amount of protrusion of the lower end of the detector 81 from the bottom surface 19 of the leg is approximately the same as or slightly less than the amount of protrusion of the right driving wheel 73 and the left driving wheel 77 from the bottom surface 19 of the leg. is.

  The gear box 50 incorporates a reduction gear and an idle gear 57, and the gear box 50 has a motor 35 fixed to the upper end as shown in FIGS.

  Further, a worm 51 is fixed to the rotating shaft of the motor 35, a worm receiving gear 53 that meshes with the worm 51 is provided, and a spur gear transmission gear 55 that rotates integrally with the worm receiving gear 53 is connected to the worm receiving gear 53. A floating gear 57 that meshes with the transmission gear 55 is provided near the tip of the floating support arm 59 with the rotation center of the transmission gear 55 as the rotation center.

  In addition, a right reduction gear is disposed obliquely below and forward of the idle gear 57 located directly below the transmission gear 55, and a left reduction gear is disposed obliquely below and behind the idle gear 57 located immediately below the transmission gear 55. The right speed reduction gear and the left are set so that the tooth tip of the idle gear 57 located immediately below the transmission gear 55 is slightly in contact with the tooth tip of the right reduction gear large diameter portion 61 and the tooth tip of the left reduction gear large diameter portion 65. A reduction gear is built into the gear box 50.

  The right reduction gear small diameter portion 63 meshes with the right drive gear 71, and the left reduction gear small diameter portion 67 meshes with the left drive gear 75 via the intermediate gear 69, and the right reduction gear and the left reduction gear are The same gear has a large diameter portion and a small diameter portion, respectively, and the right drive gear 71 and the left drive gear 75 also use the same gear.

  The right drive gear 71 and the left drive gear 75 are fixed to a right drive shaft 72 and a left drive shaft 76, respectively, having a central axis as a coaxial line, and a right drive wheel 73 is driven to the left near the right tip of the right drive shaft 72. The left drive wheel 77 is fixed near the left end of the shaft 76.

  Therefore, for example, when the worm receiving gear 53 and the transmission gear 55 are rotated in the counterclockwise direction as shown in FIG. By moving rearward due to the rotation of the rotation gear, the left reduction gear is separated from the right reduction gear, and the idler gear 57 reliably meshes with the left reduction gear large-diameter portion 65, and the left drive gear 75 via the left reduction gear and the intermediate gear 69, and the left The drive wheel 77 can be rotated.

  When the motor 35 is rotated forward, as shown in FIG. 7B, the idle gear 57 is moved forward by the rotation of the transmission gear 55 so that it is separated from the left reduction gear, and the idle gear 57 is The right drive gear 71 that meshes with the right reduction gear large-diameter portion 61 reliably and the right reduction gear small-diameter portion 63, and thus the right drive wheel 73 can be rotated.

  The right drive wheel 73 and the left drive wheel 77 have a slight rotational resistance due to the sliding frictional force of the right drive shaft 72 and the left drive shaft 76, and rotate forward when the drive force from the motor 35 is transmitted. Is what you do.

  The detector 81 arranged in front of the center of the leg bottom surface 19 has a columnar center electrode 83 at the center and a head at the lower end of the center electrode 83, as shown in FIG. When the running surface is wet, it is easy to transmit electric potential to the moisture on the running surface.

  Further, the detector 81 has a cylindrical tube electrode 87 around the center electrode 83 via a spacer 89, and the lower end of the tube electrode 87 is slightly larger than the head diameter of the center electrode 83. It has an annular electrode 85 that is a circular disc with a through hole of diameter.

  The annular electrode 85 is disposed at a position slightly higher than the position of the front end surface of the head of the center electrode 83 so that a slight gap is formed between the annular electrode 85 and the traveling surface. is.

  Further, as shown in FIG. 9, the control unit 41 accommodated in the control box 40 includes an audio memory 45 for storing audio data, a control IC 43 composed of a CPU, ROM and RAM, and audio data from the control IC 43. And a motor driver 47 for rotating or stopping the motor 35 based on a control signal from the control IC 43, and a detection circuit 48 for detecting the output state of the detector 81. Thing.

  When the power switch 33 is turned on, the control IC 43 drives the motor 35 via the motor driver 47 and supplies a high frequency voltage of about 1 kilohertz to the detector 81 as a detection signal.

  Therefore, in the detector 81, a very small current can flow due to the capacitance between the center electrode 83 and the cylindrical electrode 87. When the head of the center electrode 83 comes into contact with the wet position of the running surface, the moisture on the road surface And the annular electrode 85 is added, the amount of current flowing in the detection signal increases, the current value of the detection signal increases, and the increase in the current value is detected by the detection circuit 48. Can be detected.

  In addition, the frequency of this detection signal is sufficient if it is a predetermined frequency of several hundred hertz to several kilohertz.

  The control operation of the control IC 43 is to start the control when the power switch 33 is turned on. As shown in FIG. After performing S101), audio output processing (S105) is performed in which predetermined audio data is read from the audio memory 45 and the speaker 37 outputs audio.

  In this first audio output, you will output sounds such as “Oh, I'll do my best” and “I am ...”.

  Then, a motor forward rotation start process (S110) for starting the output of the forward rotation signal to the motor 35 is performed, the motor 35 is rotated forward, and a detection signal is output to the detector 81, whereby a line drawn with water is formed. Wet position detection judgment (S113) for detecting the input of the detection signal from the detection circuit 48 when the center electrode 83 of the detector 81 is in contact is made to judge whether or not a line drawn with water has been detected. On the other hand, the time lapse judgment (S115) is performed to determine whether or not the predetermined set time T1 has elapsed.

  Thus, when the motor 35 starts to rotate forward, the idle gear 57 meshes with the right reduction gear as described above to rotate the right drive gear 71 and the right drive wheel 73, and the left drive wheel 77 is stopped. The right drive wheel 73 can start moving forward.

  For this reason, the toy body 10 turns left with the left drive wheel 77 as the turning center, and keeps turning left until the detector 81 detects the wet position of the running surface or until the set time T1 elapses. .

  This set time T1 is based on the distance between the right drive wheel 73 and the left drive wheel 77 and the moving speed of the right drive wheel 73, and the turn amount of the toy body 10 is less than 300 degrees, for example, 330 degrees, which is less than one rotation. This is the predetermined time for turning.

  When the set time T1 has passed without detecting the wet position, the motor reverse rotation start process (S120) for reversing the motor 35 is performed to detect the line drawn with water (S123). This is to continue the detection of the line drawn with water by making the wet position detection judgment (S123) while making the time passage judgment (S125), which is judgment of whether or not the set time T2 has passed.

  When the motor 35 is reversely rotated in this way, the idle gear 57 meshes with the left reduction gear to rotate the left drive gear 75 and the left drive wheel 77, and the right drive wheel 73 is stopped and the toy body 10 is stopped. Is a right turn with the right drive wheel 73 as the turning center to detect the wet position on the running surface.

  The set time T2 is a time required for the toy body 10 to turn around the right drive wheel 73 by the left drive wheel 77 and to turn the toy body 10 at a turn of nearly 400 degrees, more than one rotation. It is what.

  Further, when the set time T2 has elapsed, a count process (S131) for adding “1” to the count value N is performed, and an audio output process (S133) is performed, and the count value N is “3” or “4”. If the predetermined number of times K has been reached or not (S135) and the predetermined number of times K has not been reached, the process returns to the motor forward rotation start process (S110).

  In this audio output process (S133), the sound that is emitted from the speaker 37 when it is confused, such as “are there” or “funny”, is generated based on the data in the audio memory 45.

  Therefore, in this walking toy, when the power switch 33 is turned on, the motor 35 rotates forward about one turn around the left drive wheel 77 by the forward rotation of the motor 35 to detect the wet location on the running surface. When the left turn makes a turn of nearly one turn without detecting a wet spot, the vehicle continues to make a right turn of one more turn around the right drive wheel 73. A swivel operation is performed so as to draw a figure 8 with the detector 81 so as to detect the wet part of the surface.

  Then, the wet part detection operation is performed so as to draw a figure 8 by the detector 81 by turning left and right, and if the wet part cannot be detected, a sound is output when the motor 35 is confused and the motor 35 is further corrected. The left turn and the right turn are repeated by rotation and reverse rotation. The left turn is less than one turn, and the right turn is one extra turn. Is an 8-character with a different direction, and can detect a wet location in a wide range centering on the detection start position of the wet location.

  Further, when the wet turn cannot be detected by performing left turn and right turn so that the detector 81 draws the figure 8 for the number of times that is the predetermined number K of 3 or 4 times, the operation control process is ended. Thing.

  When the wet position is detected in the wet position detection determination (S113) during the left turn by the motor forward rotation start process (S110), or when the wet position is detected during the right turn by the motor reverse rotation start process (S120) (S123). ), A count value reset process (S141) for setting the count value N to “0” is performed to determine whether or not the set time T3 has elapsed (S143). When T3 has elapsed, the polarity switching process (S145) is performed to switch the rotation direction of the motor 35 to the opposite direction.

  This set time T3 is a time required for turning the toy body 10 by about 20 degrees by rotating the right drive wheel 73 or the left drive wheel 77, and it is determined whether or not the set time T3 has elapsed. (S143) measures the elapsed time from when the detector 81 no longer detects a wet spot.

  Therefore, when the detector 81 detects a wet location during a right turn and a detection signal is input from the detection circuit 48 to the control IC 43, the detector 81 continues to turn right even if the detection signal is not input. After passing through the wet part, the right turn is further performed about 20 degrees, and then the motor 35 is rotated in the reverse direction to make a left turn, and the wet position is detected again by the detector 81 (S147). ).

  When the wet position is detected again in this wet position detection determination (S147), the sound output (S151) is performed and the process returns to the determination (S143) as to whether or not the set time T3 has elapsed. The line is turned while repeating the right turn and the left turn alternately so that the left turn is continued about 20 degrees after the detection is stopped, the right turn is performed by the polarity switching process (S145), and the wet position detection judgment (S147) is performed. Wet position detection judgment (S147) to detect the wet location that continues in the shape.

  For this reason, when the wet location is drawn on the running surface in a straight line, for example, when the right drive wheel 73 is stopped and the wet location is detected by turning right, even if the wet location is not detected, it is further left The drive wheel 77 continues to turn right by about 20 degrees due to the forward rotation of the drive wheel 77, then the left drive wheel 77 is stopped, and the left drive wheel 73 starts to turn left by the forward rotation of the right drive wheel 73. The right driving wheel 73 and the left driving wheel 77 are rotated so that the right driving wheel 73 is stopped and the right driving wheel 73 is stopped and the left driving wheel 77 is rotated so as to turn about 20 degrees after the point is no longer detected. It is the one that moves forward by alternately rotating.

  At this time, “Ichi” or “Nii” command voices are alternately output as voice output, and voices such as “I, Kanbaruyo” are also output.

  In addition, in the wet position detection determination (S147) after the polarity switching process (S145) is performed, a time passage determination (S149), which is a determination as to whether or not the set time T4 has passed, is performed together to detect a wet location. When the set time T4 has passed, the rotation direction determination (S155) is performed to determine whether or not the rotation direction of the motor 35 is in the forward rotation state by the passage of time determination (S149). When the direction is the direction, the process returns to the motor reverse rotation start process (S110), and when the rotation direction of the motor 35 is the reverse direction, the process returns to the motor normal rotation start process (S120) to rotate the toy main body 10 by about one rotation. Is to detect.

  As the set time T4, the time required for the toy body 10 to turn about 90 degrees by the forward rotation of the right drive wheel 73 or the left drive wheel 77 is set, and the line drawn with water on the running surface is curved. Even in this case, this walking toy can turn the direction of the toy body 10 to the right or left to nearly 90 degrees and detect the wet location by the detector 81, and the line drawn on the waterproof sheet is bent. Even when the toy body 10 moves, the left and right sides of the toy body 10 are alternately moved forward along the curve to continue the movement that appears to be walking along the line.

  The water supply sheet for running the walking toy is a square or rectangular sheet having a size of about several tens of centimeters to 1 meter, and a porous or fibrous sheet is laminated with the back surface being a waterproof sheet. It is a sheet. In addition, a water pen that has a built-in water tank and can transfer moisture from the nib to a sheet, etc., and a waterproof sheet may be combined with a walking toy.

  In the case of this combination, since the back surface is a waterproof sheet and is a laminated sheet that can contain moisture, it can be prevented from inadvertently getting wet under and around the sheet, as shown in FIG. Draw a line on the water absorbent sheet 100 with the water pen 110 and place it on the water absorbent sheet 100 so that this walking toy is placed near the line drawn with water, and draw it with water by turning on the power switch 33 You can walk along line 115 of the line.

  Therefore, even if a line is drawn with water on the water absorbent sheet 100, moisture does not escape to the back of the sheet and moisten the floor or table, so you can play with various lines 115 with confidence.

  Then, in a gentle curve or straight line, the left and right sides of the toy body 10 are alternately advanced along the line 115, and in a curve with a blurred or sudden change, the line 115 makes a full turn so that it returns to its original position. In order to stop and rotate several times, or generate various commands, such as commands, energetic voices, confused voices, etc., various curved lines 115 are drawn and varied in appearance. It is something that you can play and have fun playing.

  Note that the water absorbing sheet 100 may be a water absorbing sheet 100 in which a colored layer in which pigments or the like are dispersed is laminated and water is applied by a water pen 110 or the like, and the water absorbing sheet 100 changes color. 115 can be clearly seen, and you can enjoy walking along the line 115 of this walking toy.

  Also, without using a specific water-absorbing sheet 100, walking along the line 115 of the line drawn with water also by drawing a line with water on an appropriate sheet that can permeate water, such as felt or cardboard. It is something that can be done.

  The determination of whether or not the set time T3 has elapsed (S143) is not limited to the measurement of the elapsed time from when the detector 81 no longer detects the wet location. Sometimes it is possible to measure the time elapsed since the point was detected.

  The present invention can provide a walking toy that can be happily played by drawing a line 115 with water on the water-absorbing sheet 100 so that the mobile body travels like a walk along the line 115.
