- Heretofore, Hovercraft (trade name), an air cushion vehicle or the like has been generally known as a ground effect machine or a vehicle which travels utilizing a lift force of an air cushion contained between a bottom surface of an airframe and a running surface such as a ground or water surface on a lower side, or ground effects of wings. As a toy which travels under remote control utilizing a principle of such ground effect machine, the present applicant discloses a technology concerning an air cushion toy in which a skirt portion formed into an expandable/contractible bag shape is attached to a lower peripheral edge of a main body, and air is sucked from the outside by a blower for floating disposed in the main body to introduce the air into a main body bottom part surrounded with the skirt portion. Moreover, the air is introduced into the skirt portion to expand the portion, the main body is accordingly floated, and a blower for propelling is disposed in an upper part of the main body (see, e.g., Japanese Utility Model Publication No. 6-20559 (second to sixth pages, FIGS. 1 to 9)).
- In the conventional air cushion toy, the air is fed into the skirt portion disposed on the main body lower part peripheral edge by the blower for floating disposed in the main body to expand the skirt portion, the air is fed to the bottom part of the main body surrounded with the skirt portion, and the air is circulated between a lower-part side of the expanded skirt portion and a running surface such as a ground surface to float the airframe from the running surface. Therefore, the blower for floating having a large output has been required for uniformly circulating the air required for expanding or floating the skirt portion. To run the main body and freely change a direction, it has been necessary to dispose two blowers for propelling in the upper part of the main body, or install a mechanism which varies an air feed direction by means of one blower for propelling. Therefore, a large driving power supply is required for driving the blower for flying or propelling, and there is a fear that power consumption increases and flight for a long time cannot be performed.

In this case, even when the rotation speeds of the first andsecond propellers airframe 11 is balanced, and theairframe 11 can be moved backwards without swiveling counterclockwise or clockwise. - Next, to swivel clockwise the floated radio
control flying toy 10, as shown inFIG. 13 , when theright operation lever 37 is rotated downwards with the fingertip, and theleft operation lever 38 is rotated upwards with the fingertip in theoperating section 33 of thetransmitter 30, the rotation speeds of the front rightsecond propeller 16 b and the rear leftthird propeller 16 c rise in accordance with the rises of the driving outputs of the second and third second driving means 17 b and 17 c corresponding to the respective levers. Since these second andthird propellers FIG. 2 , the rises of the rotation speeds generate a force for swiveling clockwise theairframe 11. Therefore, the floatedairframe 11 can be swiveled clockwise by performing the lever operation shown inFIG. 13 . It is to be noted that it has been confirmed that the increase of the feed air amount accompanying the rises of the rotation speeds of the second andthird propellers - Next, to swivel counterclockwise the floated radio
control flying toy 10, as shown inFIG. 14 , when theright operation lever 37 is rotated upwards with the fingertip, and theleft operation lever 38 is rotated downwards with the fingertip in theoperating section 33 of thetransmitter 30, the rotation speeds of the rear rightfourth propeller 16 d and the rear leftfirst propeller 16 a rise in accordance with the rises of the driving outputs of the fourth and first driving means 17 d and 17 a corresponding to the respective levers. Since these fourth andfirst propellers FIG. 2 , the rises of the rotation speeds generate a force for swiveling counterclockwise theairframe 11. Therefore, the floated radiocontrol flying toy 10 can be swiveled counterclockwise by means of the lever operation shown inFIG. 14 . It is to be noted that it has been confirmed that the increase of the feed air amount accompanying the rises of the rotation speeds of the fourth andfirst propellers - As described above, in the radio

A pair of first andfourth propellers third propellers transmitter 30, thecontrol unit 20 controls the driving outputs of the first to fourth driving means 17 a, 17 b, 17 c, and 17 d, respectively. Moreover, to float the airframe, the first tofourth propellers fourth propellers second propellers third propellers fourth propellers control flying toy 10 of the present embodiment, a structure is simplified, a large driving power supply is not required for driving the blower for floating or propelling unlike a conventional air cushion toy, power consumption can be reduced, long-time flight is possible, and the toy can be enjoyed by floating and freely flying the toy above the flat running surface 1. - In the radio
control flying toy 10 of the first embodiment, there has been described the example in which the pair of first andfourth propellers third propellers transmitter 30. However, conversely, even when the driving outputs are lowered from 100% to 60%, the running can be controlled. In this case, the running operation by the same lever operation differs.

In this case, even when the rotation speeds of the first andsecond propellers airframe 11 is balanced, and theairframe 11 can be moved backwards without swiveling. - Next, to swivel clockwise the floated radio
control flying toy 40, as shown inFIG. 20 , both or one of theleft operation buttons lower operation button 53 is operated with the fingertip in theoperating section 33 of thetransmitter 50. When the button is operated in this manner, the driving output of the corresponding third driving means 17 c rises from 60% to 100%, and the rotation speed of thethird propeller 16 c rises. This rise of the rotation speed of thethird propeller 16 c generates a force to swivel thethird propeller 16 c in a clockwise direction opposite to the counterclockwise rotating direction in theairframe 11. Therefore, as shown inFIG. 20 , the floated radiocontrol flying toy 40 can be swiveled clockwise by operating the button. In this case, since a force to move theairframe 11 is simultaneously added owing to the increase of the air feed amount accompanying the rise of the rotation speed of thethird propeller 16 c, an operation different from that in clockwise swiveling of the first embodiment is performed. It is to be noted that in a case where both of theleft operation buttons third propellers airframe 11 moves rightwards. - Next, to swivel the floated radio
control flying toy 40 counterclockwise, as shown inFIG. 21 , both or one of theright operation buttons lower operation button 54 is operated with the fingertip in theoperating section 33 of thetransmitter 50. When the button is operated in this manner, the driving output of the corresponding fourth driving means 17 d rises from 60% to 100%, and the rotation speed of thethird propeller 16 d rises. This rise of the rotation speed of thefourth propeller 16 d generates a force to swivel thefourth propeller 16 d in a counterclockwise direction opposite to the clockwise rotating direction in theairframe 11. Therefore, as shown inFIG. 21 , the floated radiocontrol flying toy 40 can be swiveled counterclockwise by operating the button. In this case, since a force to move theairframe 11 is simultaneously added owing to the increase of the air feed amount accompanying the rise of the rotation speed of thefourth propeller 16 d, an operation different from that in the counterclockwise swiveling of the first embodiment is performed. It is to be noted that in a case where both of theright operation buttons fourth propeller airframe 11 moves leftwards. - As described above, in the radio
control flying toy 40 of the second embodiment of the present invention, the first tofourth propellers airframe 11 in the same manner as in the first embodiment. Moreover, thetransmitter 50 raises the driving outputs of the first to fourth driving means 17 a, 17 b, 17 c, and 17 d corresponding to the fouroperation buttons operation buttons - In the radio
control flying toy 40 of the second embodiment, there has been described the example in which the left first andthird propellers fourth propeller transmitter 30, but the driving outputs may be conversely lowered from 100% to 60%. In this case, the running operation by the same lever operation differs. - It is to be noted that in the first and second embodiments, the
airframe 11 may be formed into an arbitrary shape as long as the airframe has theflat bottom surface 14 parallel to the running surface 1 on the lower side, and is entirely formed into the rectangular plate shape, and the first tofourth propellers transmitter 30 of the first embodiment, and theoperation buttons transmitter 50 of the second embodiment may be constituted so as to be operated to thereby raise or lower the driving outputs of the corresponding first to fourth driving means 17 a, 17 b, 17 c, and 17 d, respectively. Furthermore, the radiocontrol flying toy 10 of the first embodiment can be operated with thetransmitter 50 in the same manner as in the second embodiment, and the radiocontrol flying toy 40 of the second embodiment can be operated with thetransmitter 30 in the same manner as in the first embodiment. - The present invention is applicable to a radio control flying toy in which air is fed toward a bottom-surface side of an airframe so that the airframe can be floated above a flat running surface, and freely flied.
