[Example] Hereinafter, an example of the present invention will be described based on the drawings.

Figures 1 to 6 A and B show an embodiment of the present invention. As shown in the figures, the present invention is applied to a deformable toy that changes form between a car and a robot to create a running toy. be. It goes without saying that the present invention can also be applied to shapes and structures other than those shown in the figures.

The traveling body 1 has a box-shaped base 2, a gate-shaped sheath 3 attached to it, and a body 4 having the outer shape of a car.
A roof 5 and a power supply mounting part 6 located on the roof 5 are assembled. The base 2 houses a traveling mechanism A and a deformation mechanism B, has a neck 7 in the form of a robot fixed to its front end, and rotatably supports rear wheels 8, 8 at its rear end. The chassis 3 is formed by rotatably supporting two arms 9, 9 at the central portions of the sides of the base 2, and having front wheels 10, 10 pivotally supported at the front end. The rear half of the body 4 is fixed to the base 2, but the front end is divided into two parts and is journalled on the base 2 to form arms in the robot form (hereinafter referred to as arm parts 11, 11). . The roof 5 also serves as a part of the deformation mechanism B, and is capable of sliding along the upper surface of the body 4. Furthermore, the power supply mounting section 6 is mounted on the body 4.
It is fixed on the top surface, with a microphone 13 protruding from the front end of the box, and battery boxes 1 on both sides.
4, 14 are provided with a robot-shaped indicator wheel 15 at their rear ends.

Next, the traveling mechanism A will be explained. The traveling mechanism A includes a plurality of intermediate gears 19 and 20 between a pinion gear 17 attached to a motor 16 and a gear 18 coaxial with the rear wheel 8.
It is constructed by arranging. This traveling mechanism A
The rotation direction is changed as the motor 16 rotates in the forward and reverse directions, and the rear wheels 8 are rotated in the forward and reverse directions to move the traveling body 1 forward and backward. Of course, if the motor 16 is stopped, the toy main body 1 cannot move forward.

The deformation mechanism B is mainly formed by disposing a plurality of intermediate gears 25, 26, 27 between the pinion gear 22 of the second motor 21 and the gear 24 attached to the support pin 23 of the arm 9 that supports the front wheel 10. I did it,
It consists of a mechanism for deforming the chassis 3 and a mechanism for deforming the arm 11. The mechanism for transforming the chassis 3 is based on the motor 21 and the gear group described above. The rotation of the motor 21 rotates the support pin 23, and in conjunction with this, the arm 9 is rotated to transform the entire chassis 3 into the form of an automobile. The position is changed from the front wheel position to the leg position in the robot form, that is, the position where the rear wheels 8 and front wheels 10 are connected.

The mechanism for deforming the arm portion 11 is constructed by engaging a cam portion 28 formed at the support pin attachment portion of the arm 9 with two protrusions 29 protruding from the lower surface of the roof 5. The projecting piece 29 is inserted into an opening 30 provided in the roof 5, and the upper surface of the body 4 is loosely sandwiched between the integrally formed sliding piece 31. The sliding piece 31 is formed into a substantially U-shape and is fixed to the projecting piece 29, and a spring 12 is applied between the corner portion 32 and a position slightly closer to the tip than the bearing position of the arm portion 11 relative to the base 2. I have given it to you. The cam part 28 of the arm 9 has a stepped part 35 formed on the peripheral edge between two protrusions 33 and 34, and in the form of an automobile, as shown in FIG. The protruding piece 29 of No. 5 is pressed backward. To explain the deformation operation here, the motor 21 rotates forward, the arm 9 begins to rotate downward, and the protruding piece 29 moves toward the cam portion 28.
When it passes over the peripheral edge of and comes into contact with the second protrusion 34,
The protruding piece 29 is pushed forward, and the roof 5 and sliding piece 31 are also moved forward accordingly. Then, the arm portion 11 is moved to the base 2 by the spring 12.
The head 7 is pushed outward at a position deviated from the supporting position thereof, and opens at a substantially right angle as shown in the figure, exposing the head 7. The roof 5 also rises to form arms in the form of a robot. Further, as the arm 9 rotates, the front end side of the toy main body 1 is gradually lifted, and when the front wheel 10 comes into contact with the rear wheel 8, it becomes approximately upright. At this time, the traveling body 1 is supported at three points by the front wheels 10 and the support wheels 15, and stands stably upright.

When the motor 21 is rotated in the opposite direction, the arm 9 begins to rotate upward, and the stepped portion 35 of the cam portion 28 comes into contact with the protruding piece 29 for a while, pushing the protruding piece 29 backward. When removed from the step 35, the first protrusion 33 pushes the protrusion 29 back to its original position, and along with this, the roof 5 also returns to its original position.

Next, the control device Z for the traveling mechanism A and the deformation mechanism B will be explained. This control device Z is arranged between the microphone 13 and both motors 16 and 21, and includes an amplifier section 40 that constitutes a sound detection means together with the microphone 13.
and a sound detection section 43 comprising two comparison sections 41 and 42.
and switching parts 44, 45 as switching means disposed between both comparison parts 41, 42 and both motors 16, 21. Each part is constituted by an electronic circuit, and any part may be used as long as it can perform the functions described below. The comparison units 41 and 42 are
The first sound detection means and the second sound detection means are respectively activated by different sounds.
A circuit using two operational amplifiers IC46 and 46 can be considered as shown in Figure B. That is, the sound detecting sections 43 operate in response to electrical signals of respective predetermined frequencies corresponding to predetermined constant sounds, in other words, the sounds picked up by the microphone 13 and amplified by the amplifier section 40,
It is designed to generate an output signal, and can operate in response to various sounds by changing the operating value of the operational amplifier IC46 using a variable resistor VR connected to the offset null. Switching parts 44, 45
This can be realized by a circuit using a transistor or the like. That is, any known circuit can be used as long as it causes the motors 16 and 21 to stop, rotate forward, stop, reverse, and stop in response to the output signal of the sound detection section 43.

Next, I will explain the overall operation of this toy. 4 in the diagram
Reference numeral 7 designates a suitably selected sound-producing toy that can produce a large number of sounds by operating the keyboard 49, but here, for the sake of explanation, we will use the sound-producing toy 47 to produce the sounds C (C) and G (G). Let's play. For this reason, the control device Z
The operational amplifiers IC46 are also adjusted respectively, and the comparison section 41
It is assumed that the comparator 42 responds to a C note and the comparison unit 42 responds to a G note.

First, switch 48 provided on the bottom of base 2.
Set to ON. At this time, if the vehicle was in a state other than stopped during the previous operation, it will start running or deforming, but it is assumed that no changes occur and the vehicle remains in the form of an automobile.

When the sound toy 47 first emits the sound C, the microphone 13 picks up the sound C, the comparison section 41 and the switching section 44 in the control device Z operate, and the motor 16 rotates in the forward direction (according to the previous operation). Although the rotation may be reversed, it is assumed that the rotation is forward.) Then, the traveling mechanism A operates as described above, the rear wheels 8 rotate, and the traveling body 1 moves forward. Then, when the second sound C is emitted, the microphone 13 picks it up again, and the switching section 44 is turned OFF based on the output signal of the comparison section 41, and the motor 16 is stopped.
The traveling body 1 also stops from the forward state. When the third C sound is emitted, the switching unit 44 operates in the opposite direction to the forward state, the motor 16 rotates in the reverse direction, and the traveling body 1 moves backward. Furthermore, when the fourth C sound is emitted, the traveling body 1 stops, and this process is repeated thereafter.

Then, the deformation motion starts from the sound toy to the G.
When the sound is emitted, the microphone 13 picks up this G sound, and the comparison section 42 and switching section 45 in the control device Z are activated, causing the motor 21 to rotate in the forward direction (in this case, it may also rotate in the reverse direction depending on the previous operation). However, it is assumed that the rotation is in the normal direction.) Then, the deformation mechanism B operates as described above, and the chassis 3 rotates.
The traveling body 1 transforms from a car to a robot. At this time, when the C sound is emitted, the traveling body 1 is transformed and at the same time runs and stops as described above, so that the user can experience an even more interesting transformation operation. When the second G sound is emitted, the microphone 13 picks it up again, and the output signal from the comparison section 42 turns off the switching section 45, which turns off the motor 21.
stops and the deformation operation stops. In this case, you can freely stop the transformation during the transformation or after the transformation is completed, and the C
Running and stopping operations can also be performed using sound. When the third G sound is emitted, the switching part 45 operates in the opposite direction to the forward state, the motor 21 rotates in the reverse direction, and the chassis 3 performs a rotational return operation, changing from a robot to a car. . Even in this state, operation using the C sound is possible. Furthermore, when the fourth G sound is emitted, the deformation operation stops again, and the above process is repeated. That is, in the illustrated example, six movement patterns can be formed using two sounds. Further, although the illustrated example has a traveling mechanism A and a deforming mechanism B as operating mechanisms, other combinations may be used, for example, two deforming mechanisms may be provided separately from the traveling device.

[Effects] As explained above, the running toy according to the present invention uses the sound sensor and the control device to drive the two operating mechanisms of the running body to perform the running operation, and the chassis consisting of the arm rotates to move the front wheels to the rear. By controlling the robot's transformation into a shape that is close to the ring, it becomes interesting for adults as it allows remote control of multiple patterns using sounds, which is not found in conventional transforming toys. This has the effect of not only allowing children to engage in dreamy play, but also to arouse scientific interest in sounds and the movements of objects.

Moreover, the present invention makes it possible to operate the traveling mechanism while rotating the chassis and changing the form from a car to a robot, so even in the robot form, the front wheels, rear wheels, support wheels, etc. This has the effect of making driving possible and further deepening the interest.
