  However, in the conventional helicopter toy described above, the toy body is simply levitated in the air by controlling the forward / reverse rotation of the driving motor to be in the hovering state. In order to achieve this, there is a problem that the steering operation is troublesome and complicated.

  In particular, such a conventional helicopter toy has no measures such as detecting an obstacle or the like, and has a problem that it is difficult to perform a steering operation.

  The present invention has been made in view of such circumstances, and an object of the present invention is to obtain a helicopter toy that can be very easily floated in the air and automatically maintained in a hovering state.

  In order to meet such an object, a helicopter toy according to the present invention (the invention according to claim 1) is a toy that floats by a propeller that can be levitated by remote control operation. A distance sensor that measures the distance to the obstacle in up to six directions, left and right, and front and rear, and a hovering control unit that maintains a stationary state in the air at a predetermined position based on the measurement result of the distance sensor It is characterized by being.

The distance is measured according to the intensity of infrared rays.

  The toy that floats by the propeller according to the present invention (the invention according to claim 4) is the toy that floats by the propeller according to claim 2, wherein the infrared sensor uses the characteristics of the infrared sensor, changes the frequency of the infrared, The distance is measured by the frequency of the infrared rays that have been reflected back.

  A toy floating by a propeller according to the present invention (invention of claim 5) is characterized in that in the toy floating by the propeller of claim 1, an ultrasonic sensor is used as a distance sensor.

  As described above, according to the helicopter toy according to the present invention, based on the measurement results of the plurality of distance sensors and the distance sensor, the distance to the obstacle in a plurality of directions is appropriately grasped, and the air position It is very easy and automatic to float and hover in the hovering state, and an interesting flying toy can be obtained.

  Furthermore, according to the helicopter toy according to the present invention, there is an advantage that a flight operation such as advancing, retreating, or turning from an airborne state can be easily performed.

1 to 3 show an embodiment of a helicopter toy according to the present invention.
In these figures, the copter toy indicated by reference numeral 1 includes a main rotor 4 as a propeller at the top of the toy body 2 and a tail rotor 5 at the rear. In addition, 3 is a leg part and has other necessary members.

  According to the present invention, in the helicopter toy 1 having the above-described configuration, the helicopter toy main body 2 includes distance sensors 11 to 16 that measure distances to obstacles in up and down, left and right, and up and down six directions. . Furthermore, a hovering control unit 20 is provided for maintaining a stationary state in the air at a predetermined position indoors based on the measurement results of these distance sensors 11-16.

  Here, in this embodiment, as the distance sensors 11 to 16, etc., infrared sensors that can detect the distance to the obstacle by emitting infrared rays and receiving the reflected light are used. .

  Here, the infrared sensor is configured to change the intensity of infrared output, for example, and to measure the distance based on the intensity of infrared light that has been reflected.

  And it is good to control the output of the main rotor 4 which is a propeller, and the tail rotor 5 by measuring and recognizing the distance to an obstruction with such an infrared sensor. That is, when the obstacle approaches a little, the output of the propeller is slightly increased, and when the obstacle approaches considerably, the outputs of the main rotor 4 and the tail rotor 5 that are the propellers are greatly increased, thereby making it possible to control according to the distance. It is.

  Here, as a distance measuring method using the above-described infrared sensor, there is a method of measuring the distance by using the infrared sensor characteristic, changing the frequency of the infrared light, and returning the reflected infrared frequency. It can be measured by various methods.

  The helicopter toy main body 2 is appropriately operated by radio control by the remote controller 30 to perform a flight operation.

FIG. 2 shows a case where the helicopter toy 1 according to the present invention is levitated indoors.
That is, in this FIG. 2, the code | symbol 7 is indoors and the floor surface 8, the ceiling 9, the wall surface 10, etc. exist in the four directions.

In such a configuration, the remote control control unit 30 sends a steering signal to the reception unit 23 and the control unit 20 drives the helicopter drive unit 22, thereby causing the helicopter toy 1 to fly in the air in the indoor 7. Can be landed.
At this time, the distance sensors 11 to 16 provided in the helicopter toy main body 2 can detect whether there is an obstacle in the direction by irradiating infrared rays in the respective directions and receiving the reflection. .

For example, in FIG. 2, the hovering state can be automatically maintained at a predetermined aerial position by detecting the floor surface 8, the ceiling 9, and the wall surface 10 and obtaining the distances.
To describe this in detail, the distance can be measured by changing the frequency of the infrared rays from the sensors 11 to 16, and the spatial position can be recognized. That is, because the sensitivity varies depending on the frequency, the distance can be measured.

  According to such a helicopter toy 1, a plurality of distance sensors 11 to 16 and obstacles such as the floor 8, the wall 9, and the ceiling 10 in the indoor 7 based on the measurement results of the distance sensors 11 to 16. Appropriately grasping the distance, levitating in the aerial position and flying in a hovering state can be carried out very easily and automatically, and an interesting flying toy can be obtained.

  Moreover, according to such a helicopter toy 1, flight operations such as advancing, retreating, or turning can be easily performed in an airborne state in the indoor 7 or the like.

  In particular, in such a helicopter toy 1, the distance is measured by the distance sensors 11 to 16, so that the current state is rising, falling, or moving back and forth and left and right Can be determined, and can be stopped in the air by controlling the propellers (the main rotor 4 and the tail rotor 5).

  Then, when moving in any direction, for example, when it is descending, it is possible to cancel the downward force and raise it to the original position by increasing the rotation speed of the propeller. Moreover, by measuring the distance in the downward direction during the ascent and gradually decreasing the buoyancy due to the propeller, it is possible to shift to a stationary state when the original position is reached.

  Here, if such control control is performed suddenly, there is a risk that inertia will work and it will rise too much, but such inertia can also be stopped by controlling it stepwise according to distance. It is possible to go to the state. In addition, it cannot be overemphasized that the same thing can be said for such operation control also in the movement in another direction.

In addition, this invention is not limited to the structure demonstrated by embodiment mentioned above, It cannot be overemphasized that the shape, structure, etc. of each part which comprise the toy which floats with propellers, such as helicopter toy 1, can be changed suitably. Nor.
For example, the distance sensor is not limited to the above-described six locations, ie, the top, bottom, left, and front, but may be distance sensors 17 and 18 that are directed obliquely downward as indicated by the wavy lines in FIG. .

  Moreover, although the case where the infrared sensor was used was demonstrated as the distance sensors 11-16, 17, and 18 mentioned above, this invention is not restricted to this, The ultrasonic sensor etc. which can measure a distance by reflection time may be sufficient. .

  Further, in the above-described embodiment, the case where the helicopter toy 1 is levitated indoors or the like has been described. However, the present invention is not limited to this, and it is possible to levitate or fly similarly outdoors. Needless to say.
