And the power supply 120 which supplies a power supply to each element of an electric circuit is provided.

(Operation)
The traveling toy of the present embodiment has the above configuration, and the operation will be described below.

  The traveling toy according to the present embodiment performs control using the transmitter 100 shown in the block diagram of FIG. First, when a steering operation is performed by the transmitter 100, a steering operation signal is transmitted from the transmitter 100 via the transmission antenna 107, received by the reception antenna 111 of the receiver 110, and controlled via the super regenerative reception unit 112. A signal is supplied from the IC 113 to the motor drive amplification unit 114 connected to the steering device 25, and the motor 26 of the steering device 25 is rotated. Thereby, the tie rod 23 is moved right and left, and the front wheel 22 is steered.

  When a traveling operation is performed by the transmitter 100, a traveling operation signal is transmitted from the transmitter 100 via the transmission antenna 107, received by the reception antenna 111 of the receiver 110, and from the control IC 113 via the super regenerative reception unit 112. A signal is supplied to the motor drive amplifier 115 connected to the rear wheel drive device 95 to rotate the motor 96 of the rear wheel drive device 95. Thereby, the rear wheel 91 can be driven to move the traveling toy 1 forward or backward.

  When a deforming operation from a buggy type automobile shape to a robot shape is performed by the transmitter 100, a deformation operation signal is transmitted from the transmitter 100 via the transmitting antenna 107, received by the receiving antenna 111 of the receiver 110, and super-reproduced. A signal is supplied from the control IC 113 to the motor drive amplifying unit 116 connected to the chassis folding mechanism 50 via the mold receiving unit 112, and the motor 53 of the chassis folding mechanism 50 is rotated forward.

  3 and 4, when the motor 53 of the chassis folding mechanism 50 is driven to rotate forward, the rotation of the pinion 54, first car 55, second car 56, third car 57, fourth car 58, fifth car 59 is rotated forward. Here, the normal rotation of the motor refers to a rotation in which the fifth wheel & pinion 59 rotates counterclockwise when FIG. 4 is viewed from the front. With the rotation of the fifth wheel & pinion 59, the fan-shaped gear 60 rotates around the drive shaft 63. At the same time, the storage case 61 fixed to the fan-shaped gear 60 also rotates around the drive shaft 63 of the fan-shaped gear 60, so that the angle formed between the front chassis 30 and the storage case 61 changes from substantially horizontal to an acute angle, and 5 The rotation shaft of the number wheel 59 and the drive shaft 63 of the fan-shaped gear 60 rise in the vertical direction (FIG. 4b). As the drive shaft 63 rises in the vertical direction, the chassis 10 is bent and the front chassis 30 is raised.

  At this time, the rear chassis 80 also rotates with respect to the chassis folding means 30 about the connecting shaft 13 (FIG. 2). In FIG. 2, the fixed part 82 installed on the connecting shaft 13 that connects the chassis folding means 52 and the rear chassis 80 regulates the rotational direction of the rear chassis 80, so that the rear part is viewed from the front when FIG. 4 is viewed from the front. The chassis 80 does not rotate counterclockwise with respect to the chassis folding means 52. Accordingly, the rear chassis 80 also rises.

  The length of the front chassis 30 is longer than the length of the rear chassis 80, and the chassis folding means 52 is provided in the middle of the forward chassis 30, so the chassis 10 is bent and the front chassis 30 is raised. At times, the front chassis 30 is higher than the rear chassis 80, and a portion corresponding to the robot-shaped body 2 is formed.

  Further, as shown in FIG. 4, the connecting arm 76 of the chassis folding means 52 swings around a projection 77 provided at the center of the front chassis case 31 and is provided on the rear chassis 80 side. The receptacle 78 is rotated clockwise as viewed from the front in FIG. Since the arm receiver 78 is biased by a spring, an impact generated when the chassis is bent is absorbed.

In conjunction with the change in the angle between the front chassis 30 and the storage case 61 from approximately horizontal to an acute angle, the angle between the front chassis 30 and the dome-shaped cover 62 of the chassis folding means 52 also changes from approximately horizontal to an acute angle. Then, the sleeve 34 of the upper body forming means 33 attached to the both end portions of the dome-shaped cover 62 rises. As shown in FIGS. 6 and 8, the sleeve 34 rises and the grooved slider 38 rotates around the shaft 36, and the pin 39 ′ of the connecting part 39 connected to the head 40 is the groove of the grooved slider 38. Is moved forward from the position of the rear end of the traveling direction, the head 40 changes from substantially parallel to substantially vertical with respect to the front chassis 30, and the head 40 rises.

  At the same time, the rotation of the grooved slider 38 changes the plane including the shaft 36 and the shaft 37 from approximately parallel to approximately vertical with respect to the front chassis 30. At the same time, the cylindrical parts 35 a of the both arm portions 35 inserted and fixed to the shafts 36 and 37 rotate around the shaft 37, so that both arm portions 35 become substantially perpendicular to the front chassis 30.

  As shown in FIG. 7, along with the rotation of the cylindrical part 35 a, the protrusion 35 a ′ of the cylindrical part 35 a extends from the inside of the front chassis case 31 along the sliding groove 31 a ′ of the curved part 31 a of the forward chassis case 31. Slide outward. Thus, both arms 35 are substantially perpendicular to the front chassis 30 and move outward.

  Further, as shown in FIG. 9, the arm 71 rotates about the connecting shaft portion 72 a of the arm receiving 72 on the driven side. The posture of the traveling toy 1 is such that the front wheel support chassis 20 is in a parallel state with respect to the road surface by the arm receiver 73 having a connecting shaft portion 73a that connects the other end of the arm 71 being biased by a spring. Adjusted.

  Further, when the drive shaft 63 rotates, the protrusions 74 a and 74 b of the fixed plate 74 rotate around the drive shaft 63, and the protrusion 74 b contacts the switch piece 75 a so that the switch piece 75 a is connected to the back surface of the front chassis 30. Move in the direction. When the switch piece 75a moves to the end of the switch mechanism 75, the switch mechanism 75 is activated to stop the rotation of the motor 53 for the chassis folding mechanism 50. Thus, the deformation operation from the buggy type automobile shape to the robot shape is completed.

  When the transmitter 100 performs a deformation operation from a robot shape to a buggy type automobile shape, a deformation operation signal is transmitted through the receiving antenna 111, the super regenerative reception unit 112, the control IC 113, and the motor drive amplification unit 116 to bend the chassis. The motor 53 of the mechanism 50 is reversed. In FIG. 4, when the motor 53 of the chassis folding mechanism 50 is driven in reverse, the sector gear 60 that meshes with the fifth wheel 59 rotates around the drive shaft 63. At the same time, the storage case 61 fixed to the fan-shaped gear 60 rotates around the drive shaft 63 of the fan-shaped gear 60, and the angle formed by the front chassis 30 and the storage case 61 changes from an acute angle to a substantially horizontal angle. Thus, the rotation shaft of the fifth wheel 59 and the drive shaft 63 of the fan-shaped gear 60 are lowered in the vertical direction (FIG. 4a), the chassis 10 is extended, and the front chassis 30 is tilted toward the rear chassis 80.

  At this time, the angle formed by the front chassis 30 and the dome-shaped cover 62 of the chassis folding means 52 changes from an acute angle to substantially horizontal, and the sleeve 34 of the upper body forming means 33 falls backward. At the same time, the grooved slider 38 rotates about the shaft 36 and the pin 39 ′ of the connecting part 39 connected to the head 40 slides rearwardly from the front end of the grooved slider 38 on the grooved slider 38. The head 40 changes from substantially vertical to substantially parallel to the front chassis 30 and the head 40 is accommodated. Further, as the grooved slider 38 rotates, the plane including the shaft 36 and the shaft 37 changes from substantially vertical to substantially parallel to the front chassis 30, and the cylindrical parts 35 a of both arm portions 35 become shafts. By rotating around 37, both arm portions 35 become substantially parallel to substantially perpendicular to the front chassis 30 (FIGS. 6 and 8). At the same time, the projection 35a ′ of the cylindrical part 35a slides in the sliding groove 31a ′ of the curved portion 31a of the front chassis case 31, and the both arms 35 move from the outside to the inside of the front chassis 30 (FIG. 7). ).
