Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sound sensor deformable toy that uses a sound sensor.

[Prior Art] A variety of deformable toys have been known in the past, but these toys are either deformed manually by the player or automatically deformed by the player's mechanical operation, and the deformation involves Toys and players always came into direct contact.

[Problems to be Solved] Many deformable toys, such as robots and cars, have shapes that give children dreams, and from this point of view, it has been desired that the deformation action be performed remotely. Furthermore, there was a desire for something that would use a more familiar operating method rather than the common remote control of so-called radio-controlled toys using wireless telegraphy.

[Means for solving the problem] The present invention aims to perform remote control using a sound sensor such as a microphone. Specifically, the sound sensor is mounted on a toy body equipped with a deformable A structure and a traveling mechanism. A sound sensor deformable toy, characterized in that the sound sensor generates an output signal upon reception of a predetermined sound, and the deformation mechanism and the traveling mechanism are individually movable according to the output signal of the sound sensor. be.

[Example] Embodiments of the present invention will be described below based on the drawings.

Figures 1 to 6 (a) and (b) show one embodiment of the present invention, and as shown in the figures, the present invention is applied to a transformable toy that changes shape between a car and a robot. be. It goes without saying that the present invention is also applicable to shapes and structures other than those shown in the figures.

The toy body l has a box-shaped base 2 and a gate-shaped chassis 3.
The installation is further carried out by assembling a podium 4 shaped like a car, a roof 5, and a power supply mounting part 6 located on the roof 5.

The base 2 houses the traveling mechanism A and the deformation mechanism B,
A neck 7 in the form of a robot is fixed to the front end, and a rear wheel 8.8 is rotatably supported at the 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 ends thereof. The rear half of the pod 4 is fixed to the base 2, but the front end is divided into two parts, so that it becomes an arm in robot form (hereinafter referred to as arm 11.1).
(referred to as 1) is a bearing on the base 2. The roof 5 also serves as a part of the deformation mechanism B, and is a rotating part that slides along the top surface of the podium 4. Furthermore, the power supply mounting part 6 is fixedly installed on the top surface of the podium 4, and a microphone 13 is protruded from the front end of the box part, and battery boxes 14 and 14 are provided on both sides of the box part.
A robot-shaped support wheel 15 is provided at the rear end.

Next, the traveling mechanism A will be explained. The traveling mechanism A is constructed by disposing 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. The traveling mechanism A changes the direction of rotation as the motor 16 rotates in the forward and reverse directions, rotates the rear wheel 8 in the forward and reverse directions, and moves the toy body l 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. 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 composed of the motor 21 and the gear group described above.The rotation of the motor 21 rotates the support pin 23, and accordingly the arm 9 is rotated, thereby transforming the entire chassis 3 into the form of an automobile. The position of the front wheels is changed from the position of the front wheels in the robot form to the position of the legs 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 on the arm 9 with a cam portion 28 formed in the portion and two protruding pieces 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 podium 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. A spring is installed between the sliding piece 31 and a position slightly closer to the tip of the arm portion 11 than the bearing position relative to the base 2. The 12th is the passing. The cam portion 28 of the arm 9 is
A stepped portion 35 is formed on the peripheral edge between the two protrusions 33 and 34, and in the form of an automobile, as shown in FIG. It's pushing against me. To explain the deformation operation here, when the motor 21 rotates forward and the arm 9 begins to rotate downward, the protrusion 29 passes over the peripheral edge of the cam part 28 and comes into contact with the second protrusion 34.
The protruding piece 29 is pushed forward, and the roof 5 and the sliding piece 31 move forward as well. Then, arm 1
1 is pushed outward by a spring 12 from a position deviated from the position where it is supported on the base 2, so that it opens at a substantially right angle as shown in the figure and exposes the head 7. The roof 5 also rises to form the chest of the robot. Further, as the arm 9 rotates, the front end of the toy body 1 is gradually lifted up, and when the front wheel 10 comes into contact with the rear wheel 8, it becomes approximately upright. At this time, the toy main body l has a front wheel 10.
With the support wheels 15 and 15, it is supported at three points 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 has a microphone 13 and both motors 16.2.
1, an amplifier section 40, a sound detection section 43 comprising two comparison sections 41.42, and a one-car comparison section 41.4.
2 and a switching section 44.45 arranged between the two motors 16.21. Each part is constituted by an electronic circuit, and any type of part may be used as long as it can perform the functions described below. As an example of the comparison parts 41 and 42, for example, FIG.
A circuit using two operational amplifier ICs 46, 46 can be considered as shown in (b). That is, the sound detection section 43 picks up a predetermined constant sound, in other words, the microphone 13 and outputs it to the amplifier section 4.
It is designed to operate only in response to an electrical signal of a predetermined frequency corresponding to the sound amplified by 0, and generate an output signal.The variable resistor VR connects the operating value of the operational amplifier IC46 to the offset null. It can be changed and operated in response to various sounds. Switching section 44.4
This can be realized by a circuit using five transistors or the like. That is, in response to the output signal of the sound detection section 43, the motors 16 and 21
Any known circuit can be used as long as it stops, rotates forward, stops, reverses, and stops.

Next, we will explain the overall operation of this toy. 47 in Figure 1 is an appropriately selected sound-producing toy. Many sounds can be produced by operating the keyboard 49. Here, for convenience of explanation, we will use this sound-producing toy 47 to make C ( Have the children play by making the C) and G (N) sounds. For this reason, the operational amplifier ICs 46 of the control device Z are also adjusted, so that the comparator 41 responds to the G sound and the comparator 42 responds to the G sound.

First, the switch 48 provided on the bottom surface of the base 2 is turned 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 G sound is first emitted from the sound toy 47, the microphone 13
picks up this G sound and compares it with the comparison section 4 in the control device Z.
1. When the switching unit 44 operates and the motor 16 rotates in the forward direction (it may rotate in the reverse direction depending on the previous operation, but it is assumed that it has rotated in the forward direction), the traveling mechanism A operates as described above and the rear wheel 8 rotates. , the toy body l moves forward. Then, when the second G sound is emitted, the microphone 13 picks it up again, and the output signal from the comparing section 41 turns off the switching section 44, the motor 16 stops, and the toy main body 1 also stops from its forward movement state. When the third G 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 toy main body l moves backward. Furthermore, when the fourth G sound is emitted, the toy main body l stops, and this is then repeated.

In the deformation operation, when the sound toy first emits a G sound, the microphone 13 picks up this G sound, the comparison section 42 and the switching section 45 in the control device Z operate, and the motor 21 rotates in the forward direction. (Also in this case, it may rotate in the opposite direction depending on the previous operation, but it is assumed to have rotated in the forward direction.)
Then, the deformation mechanism B operates as described above, the chassis 3 rotates, and the toy body 1 transforms from a car to a robot. If the G sound is emitted at the same time, the toy main body 1 will be transformed and at the same time run and stop as described above, so that the user can experience even more interesting transformation operations. When the second G sound is emitted, microphone 13 picks it up again,
The switching unit 45 is turned off by the output signal of the comparison unit 42.
F, the motor 21 stops, and the deformation operation stops. In this case, the stop operation can be freely performed during the transformation or after the transformation is completed, and the running and stopping operations can also be performed using the G sound. Then, when the third G sound is emitted, the switching unit 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 G sound is possible. Furthermore, when the fourth G sound is emitted, the deformation operation stops again, and the above process is repeated.

[Effects] As explained below, the sound sensor deformable toy according to the present invention uses a sound sensor to control the running and deformation movements of the toy body, so it is possible to use sweat-based remote control, which is not available in conventional deformable toys. This has the effect of arousing interest, allowing f-statements to engage in dreamy play, and also to arouse scientific interest in sounds and the movements of objects.
