Description

  The present invention relates to a helicopter toy that flies by remote control and a balance device that stably flies a helicopter toy.

  Nowadays, various helicopter toys that fly indoors and outdoors are proposed and provided in reality.

  In many cases, this helicopter toy is operated by ascending, descending, stopping in the air, moving forward, turning, and the like by wireless operation such as infrared rays (for example, Patent Documents 1, 2, and 3).

  In addition, a remotely operated helicopter toy that is allowed to fly indoors has been devised in various ways to improve flight stability such as hovering (stop in the air).

  For example, the helicopter toy shown in Patent Document 1 has a main rotor at the upper left and right sides of the aircraft. Then, the rotor shafts of the right rotor and the left rotor are provided on the left and right sides of the machine body so that the upper part opens to the left and right rather than the lower part so as to be V-shaped. Therefore, the simple structure enables stable ascent, descent, air stop, advance, and turn flight.

  Moreover, the helicopter toy shown in Patent Document 2 has auxiliary wings instead of stabilizers above main rotor blades that are main rotors provided on the upper part of the fuselage. Then, the auxiliary wing and the main rotor blade are attached to the rotary shaft of the main rotor blade at different angles so that the center axis lines thereof intersect. Further, the auxiliary blade is attached to the rotation shaft of the main rotor blade so that the central axis thereof can swing in the vertical direction. Further, the main rotor blade is attached to the rotating shaft of the main rotor blade with a variable pitch angle that varies the horizontal height between the blade front end and the blade rear end.

  Still further, the helicopter toy disclosed in Patent Document 2 is configured such that the main rotor blade and the auxiliary rotor blade are coupled by a link, and the center axis of the auxiliary rotor blade swings with respect to the rotation axis of the main rotor blade. The pitch angle of the main rotor blade is changed according to the rotational position of the main rotor blade. Therefore, when the rotating surface of the airframe or main rotor is tilted by the auxiliary blade that always rotates in the horizontal plane, the pitch angle is changed depending on the rotation position of the main rotor, and the rotation axis of the main rotor, that is, the airframe This makes it possible to adjust the inclination of the vehicle so that stable ascent, descent, aerial stop, advance, and turn flight are possible.

  The helicopter toy shown in Patent Document 3 has an upper main rotor and a lower main rotor that rotate in reverse on the upper part of the fuselage, and has a stabilizer below the upper main rotor to increase the pitch angle of the upper main rotor. Adjustable to increase flight stability. Furthermore, the lower main rotor has a variable pitch angle in the four directions of front, rear, left and right. Accordingly, it is possible to perform stable ascending, descending, aerial stop, and forward, backward, turn, and flight that moves in parallel in the left and right directions.

  As described above, the helicopter toy is capable of stable flight while facilitating indoor flight operations.

  However, even indoors, if the airframe shakes due to disturbances such as air convection and breeze, the flight becomes unstable, which may cause a collision with a wall or a crash.

  Also, if the main rotor is suddenly rotated rapidly in order to raise the aircraft during takeoff, the aircraft will vibrate and swing due to the reaction of the rotation of the rotor, causing balance imbalance and making takeoff difficult. There was also.

  Many helicopter toys can be operated to ascend, descend, advance, retreat, aerial stop, and turn, but few are capable of operating parallel flight in the lateral direction. For this reason, when the airframe is tilted in the horizontal direction due to disturbance or imbalance of the balance, the recovery control operation cannot be performed and the aircraft is often crashed.

  The present invention eliminates the above-mentioned drawbacks, reduces the horizontal inclination, and restores the inclination quickly, thereby improving the stability in the lateral direction and the helicopter toy that improves the inclination recovery of the helicopter toy. An equilibrium device is provided.

  A helicopter toy according to the present invention includes a machine body including a main body portion and a balance device fixed to the main body portion, and the balance device is a long rod-shaped balance rod extending in the left-right direction of the machine body. The balance rod is a helicopter toy that has enormous portions at both ends and is swingably provided on the airframe.

  The balancer device for a toy according to the present invention includes a support main body having a flat plate-like fixing plate, and a swing support that can swing relative to the support main body. This is a balance device for a helicopter toy in which the balance rod is swingably attached to the support main body portion by supporting the central portion of a long rod-shaped balance rod having enormous portions at both ends by the portion.

  The helicopter toy according to the present invention is provided with a long balance rod that extends in the left-right direction of the fuselage and has enormous portions at both ends so as to be swingable. Can be stabilized.

  The balance device for a helicopter toy that swingably supports a long balance rod having an enormous portion at both ends by a support main body having a fixed plate can be easily attached to the upper part of the helicopter toy by a fixed plate. It is possible to improve the flight stability of the helicopter toy.

FIG. 7A is a diagram showing a swinging state of the balancing device provided in the helicopter toy according to the embodiment of the present invention, and FIG. FIG. 7B is a diagram illustrating a state in which the peristaltic support portion swings to the left (the body, that is, the fixed support portion tilts to the right). It is a figure which shows the inclination state of the helicopter toy which concerns on embodiment of this invention, Comprising: FIG. 8A shows a horizontal state, FIG. 8B is a figure which shows an inclination state.

  As shown in FIGS. 1 and 2, the helicopter toy according to the embodiment of the present invention has a counter-rotating main rotor 150 at the center upper portion of the fuselage 110, and a tail end portion 115 at the rear end portion. A balance rotor 180 that includes a rear rotor 116 having a horizontal plane as a rotation surface, and that supports a balance rod 197 that extends laterally from the main body 111 simulating a cabin so as to be swingable by a support 181. Helicopter toy 100.

  This helicopter toy 100 is described with the nose side forward and the main rotor 150 side upward, with the front and rear and up and down directions defined, and the left and right are symmetric in appearance, but the front direction of the body 110 The left side and the right side will be described according to the state viewed from the side.

  The helicopter toy 100 includes a fuselage 110 having a sled landing member 113 below a main body portion 111 simulating a cabin, and a pipe-shaped tail portion 115 behind the main body portion 111. A rear rotor motor 117 and a rear rotor 116 fixed to the motor shaft of the rear rotor motor 117 are provided at the ends.

  The main rotor 150 above the machine body 110 includes an upper rotor 151 and a lower rotor 161 disposed below the upper rotor 151, and rotates the upper rotor 151 and the lower rotor 161 in opposite directions.

  The lower rotor 161 has a lower rotor shaft 163 projecting upward from the main body 111 at a position slightly rearward of the main body 111, and the lower rotor head 165 provided at the upper end of the lower rotor shaft 163 is One lower rotor blade 167 is attached to the lower rotor shaft 163.

  The upper rotor 151 has an upper rotor shaft 153 that is coaxial with the lower rotor shaft 163 and penetrates the lower rotor shaft 163. Two upper rotors are provided by an upper rotor head 155 provided near the upper end of the upper rotor shaft 153. A blade 157 is attached to the upper rotor shaft 153.

  Then, when the two lower rotor blades 167 are attached to the lower rotor shaft 163 by the lower rotor head 165, the lower rotor head 165 in which the short side portions that are both ends in the long side direction of the rectangular shape are formed in a semicircular arc shape is used. The lower rotor blades 167 are attached to the vicinity of both ends in the long side direction of the lower rotor head 165 so as to be rotatable by blade pins 169, respectively. That is, the tip of each lower rotor blade 167 can be rotated back and forth in a horizontal plane around the blade pin 169 with respect to the lower rotor head 165.

  Similarly, when the two upper rotor blades 157 are attached to the upper rotor shaft 153 by the upper rotor head 155, the upper rotor head 155 in which both ends, which are rectangular short sides, are semicircular arcs, The upper rotor blades 157 are rotatably attached to the vicinity of both ends in the long side direction of the upper rotor head 155 by blade pins 169, and the tips of the upper rotor blades 157 are centered on the blade pins 169 with respect to the upper rotor head 155. It can be rotated.

  Accordingly, while the upper rotor 151 and the lower rotor 161 are rotating, the two upper rotor blades 157 and the two lower rotor blades 167 are respectively centered on the upper rotor head 155 and the lower rotor head 165 due to centrifugal force due to their own weight. As a straight line and rotate. When the tip of the upper or lower rotor blades 157, 167 hits an obstacle such as a wall, the rotor blades 157, 167 that hit the obstacle by the external force applied to the rotor blades 157, 167 from the obstacle are centered around the blade pin 169. It rotates to delay the rotation. For this reason, it is possible to prevent an impact caused by an external force from being applied to the upper and lower rotor heads 155 and 165, and thus the upper rotor shaft 153 and the lower rotor shaft 163.

  Further, the upper rotor 151 is configured such that a rectangular upper rotor head 155 having semicircular ends at both ends is rotatable about a longitudinal axis (long axis) passing through the center of the upper rotor head 155 as a rotation axis. It is attached to the shaft 153. Therefore, the pitch angle that is the elevation angle of the upper rotor blade 157 is made variable by the swinging of the upper rotor head 155 about the rotation axis.

  That is, when the upper rotor head 155 is horizontal, the two upper rotor blades 157 attached to the upper rotor head 155 by the blade pins 169 have the same pitch angle so that the front edge of each rotor blade is more than the rear edge. High position.

  However, when the upper rotor head 155 is tilted with the major axis of the upper rotor head 155 being pivoted, the upper rotor blade 157 of the two upper rotor blades 157 has a higher front edge. To increase the pitch angle. Further, the other upper rotor blade 157 is rotated so as to lower its front end edge to reduce the pitch angle.

  A stabilizer 170 is provided at the upper end of the upper rotor shaft 153, and the stabilizer 170 is attached to the upper end of the upper rotor shaft 153 by a stabilizer head 171 with a stabilizer rod 173 having a length shorter than the total length of the upper rotor 151 and the lower rotor 161. It is what

  Further, a weight 177 is provided at both ends of the stabilizer rod 173, and a rod-like link shaft 179 that connects the side of the stabilizer head 171 and the side of the upper rotor head 155 is provided.

  The stabilizer rod 173 uses a stabilizer pin 175 for a boss 176 provided at the upper end of the upper rotor shaft 153 as shown in FIG. 3, in particular, FIG. 3A, which is an enlarged view of the main part of the stabilizer 170 and the upper rotor 151. The stabilizer head 171 is attached, the axial direction of the stabilizer rod 173 and the axial direction of the stabilizer pin 175 are orthogonal to each other, and both ends of the stabilizer rod 173 can be swung up and down with the stabilizer pin 175 as a swing center.

  The direction that intersects the axial direction of the orthogonal stabilizer rod 173 and the axial direction of the stabilizer pin 175 is defined as the major axis direction of the upper rotor head 155, and the link shaft 179 is disposed on the side of the upper rotor head 155. It is what you are doing.

  Therefore, the stabilizer rod 173 is swung around the stabilizer pin 175 as a rocking center. For example, when the right end of the stabilizer rod 173 is lowered in FIG. 3, the link shaft 179 is connected to the stabilizer head 171 of the upper rotor head 155. The straight edge 155a on the upper right side is pushed down, and the straight edge 155b on the lower left side of the upper rotor head 155 is pulled up.

  Therefore, the upper rotor 151 reduces the pitch angle by pushing down the front edge of the upper rotor blade 157 on the right side shown in FIG. 3 and reduces the pitch angle by pushing down the rear edge of the upper rotor blade 157 on the left side. It's something that gets bigger.

  Further, as shown in FIG. 1 and the like, the helicopter toy 100 has a balancing device 180 attached to the upper part of the main body 111 in the fuselage 110 at a position immediately in front of the lower rotor shaft 163.

  This balancer 180 is a long rod-like balance rod 197 provided with enormous portions 199 at both ends, and is fixed to the upper part of the body 110 so that it can be swung by a support portion 181.

The balance rod 197 is arranged so as to extend to the left and right by the same length so as to be orthogonal to the longitudinal center line axis of the airframe 110, and can swing so as to move both left and right ends in the vertical direction. Therefore, a horizontal equilibrium state in which both ends are located on the same horizontal plane can be maintained by the weight balance of the balance rod 197.
The balancer 180 will be described in detail later.

  Further, as shown in FIG. 4, main motors 141 and 142 for rotating the main rotor 150, a control circuit, a battery 123, and the like are incorporated in the main body 111.

  That is, a power switch 133 is provided on the lower surface of the main body 111, and by operating the power switch 133, the operation signal is received and each part based on the operation signal is made operable.

  A power terminal 131 is provided on the lower surface of the main body 111, and when the power jack of the charger is inserted and connected to the power terminal 131, the battery 123 built in the main body 111 can be charged.

  The battery 123 is arranged near the nose of the main body 111 so that the weight balance of the helicopter toy 100 can be maintained.

  The lower surface of the main body 111 has an infrared receiver as a receiving device 135 that receives an operation signal, and can receive an operation signal from a transmitter.

  The main body 111 includes a first main motor 141, a second main motor 142, a first main motor 141, a second main motor 142, and a rear rotor motor according to an operation signal received by the receiving device 135. A control circuit board 121 having a control circuit for controlling the rotation of 117 is accommodated.

  Further, the main body 111 has an upper rotor gear 145 provided at the lower end of the upper rotor shaft 153. The upper rotor gear 145 is meshed with a pinion attached to the motor shaft of the first main motor 141, and the lower rotor is engaged. A lower rotor gear 146 is provided at the lower end of the shaft 163 and meshed with a pinion attached to the motor shaft of the second main motor 142.

  Further, the rear rotor motor 117 provided at the rear end of the tail portion 115 has a motor shaft perpendicular to the horizontal plane and a rear rotor 116 attached to the upper end of the motor shaft. The rear rotor motor 117, the first main motor 141, and the second main motor 142 are connected to the control circuit board 121 by the power line 125.

  Then, by controlling the rotation speed and rotation stop of the first main motor 141 and the second main motor 142 by the control circuit of the control circuit board 121, the rotation speeds of the upper rotor 151 and the lower rotor 161 can be controlled. Similarly, the forward / reverse rotation and stop of the rear rotor 116 can be controlled by controlling the forward / reverse rotation and rotation stop of the rear rotor motor 117 by the control circuit of the control circuit board 121.

  As described above, the helicopter toy 100 includes the main rotor 150 having the upper rotor 151 and the lower rotor 161 above the main body 111, and rotates the upper rotor 151 and the lower rotor 161 in the reverse direction. By matching the rotational speed of 151 and the rotational speed of the lower rotor 161, the direction of the airframe 110 can be fixed in one direction in the air.

  When the rotational speed of the upper rotor 151 and the lower rotor 161 is increased, the airframe 110 is raised. When the rotational speed of the upper rotor 151 and the lower rotor 161 is decreased, the airframe 110 is lowered, and the rotational speed of the upper rotor 151 is increased. And the rotational speed of the lower rotor 161 are adjusted to adjust the ascending speed and the descending speed of the airframe 110 without changing the direction of the airframe 110, and can be stopped in the air.

  Further, if a rotational speed difference between the upper rotor 151 and the lower rotor 161 is caused so as to slightly increase the rotational speed of the upper rotor 151 and slightly lower the rotational speed of the lower rotor 161, the airframe 110 While maintaining altitude or ascending or descending, the body 110 can be turned so that the nose is directed to the left, for example. Then, if the rotational speed of the upper rotor 151 and the lower rotor 161 is slightly increased so that the rotational speed of the upper rotor 151 is slightly decreased and the rotational speed of the lower rotor 161 is slightly increased, While maintaining altitude or ascending or descending, the airframe 110 can be turned so that the nose is directed to the right, for example.

  Since the rear rotor 116 is horizontally attached, when the rear rotor 116 is rotated forward, for example, the aircraft 110 is tilted slightly forward so as to lift the tail portion 115, and the flight is performed forward. Further, when the rear rotor 116 is rotated in the reverse direction, the airframe 110 can be tilted slightly rearward so as to push down the tail portion 115 to perform backward flight.

  Therefore, this toy helicopter toy 100 can be freely operated by ascending, descending, maintaining a predetermined altitude, moving forward, retreating, turning, etc. according to the operation signal. It can be easily operated.

  Further, as shown in FIG. 3, the balancer 180 has a length L2 of the balance rod 197 that is longer than the total length L1 of the fuselage 110, and is provided with a resin pipe as enormous portions 199 at both ends of the balance rod 197. Is.

  The balance rod 197 has a rod body 198 made of a thin aluminum pipe or a solid elongated rod-like body, and is curved in an arc shape so that both ends are lower than the center portion with respect to the center portion. It is.

  And the resin pipe which makes the enormous part 199 cross | intersects so that the center axis of a pipe may be in the horizontal state of the front-back direction, and may be orthogonally crossed with the axial direction of the edge part of the rod main body 198 in the balance rod 197.

  In addition, the central axis of the resin pipe that is the enormous portion 199 may be a vertical direction instead of a horizontal direction, or may be inclined in the front-rear direction. It is sufficient to make the combined axial direction orthogonal to the end axis of the rod body 198 in the balance rod 197.

  The shape of the enormous portion 199 is not limited to the pipe shape, but is a spindle shape or a teardrop shape, and the spindle or teardrop shape central axis is orthogonal to the end axis of the curved rod-shaped rod body 198. Sometimes.

  Furthermore, the shape of the enormous portion 199 may be a spherical shape, or as shown in FIG. 5A, a deformed spherical shape in which the diameter gradually increases so as to extend the end axis of the rod body 198. In this case, as shown in FIG. 5B, a cylindrical or prismatic shape having a larger diameter than the rod body 198 that extends the end axis of the rod body 198, a rod body of the balance rod 197 as shown in FIG. Various shapes such as a conical shape extending the end axis of 198 and a plate-like body such as a flat triangle or a circle extending in the front-rear direction of the body 110 (not shown) can be used.

  The support portion 181 that fixes the balance rod 197 to the upper portion of the main body 111 so as to be swingable is, as shown in FIG. The plate 185 and the rear support plate 187 have a support main body portion 183 having a U-shape opening upward.

  The support portion 181 includes a support pin 193 that passes through the vicinity of the upper end of the rod support plate 195 and the rod support plate 195 between the front support plate 185 and the rear support plate 187, and is fixed to the rod support plate 195. The swing support portion 191 is provided. The swing support portion 191 is attached to the front and rear ends of the support pin 193 so as to be rotatable with respect to the vicinity of the upper end of the front support plate 185 and the vicinity of the upper end of the rear support plate 187, and the rod support plate with the support pin 193 as the swing center. The lower end of 195 can be turned left and right.

  The support pin 193 is fixed in the vicinity of the upper ends of the front support plate 185 and the rear support plate 187, and the rod support plate 195 can be swung and rotated with respect to the support pin 193. Sometimes it is supported.

  Then, the vertical length of the rod support plate 195 is made shorter than the vertical lengths of the front support plate 185 and the rear support plate 187, and the center portion of the balance rod 197 is fixed to the lower end of the rod support plate 195. The left and right balances are adjusted so that both ends are horizontal and have the same height.

  In this way, the balance rod 197 of the balancer 180 is normally kept horizontal, with the left and right lengths from the support point being the same length. Further, as shown in FIGS. 7A and 7B, the balance rod 197 can swing left and right with the fixing plate 189 of the support main body 183 in a horizontal state.

  Then, a chassis (not shown) that fixes the first main motor 141, the second main motor 142, the battery 123, the control circuit board 121, and the like that incorporate the fixing plate 189 of the supporting main body 183 in the main body 111 in the main body 111 of the body 110. The balance device 180 is attached to the airframe 110 by being fixed to the upper surface of the airframe 110 or to the upper surface of the exterior cover of the main body 111 in the airframe 110.

  Therefore, even when the airframe 110 is tilted left and right and the support main body 183 is tilted, the balance rod 197 fixed to the lower end of the rod support plate 195 of the swing support 191 can be maintained horizontally. is there.

  When the fixing plate 189 of the support main body 183 is fixed to the chassis built in the main body 111, as shown in FIGS. 1 and 4, a groove 119 is formed at the upper end of the outer cover and the balance protruding from the outer cover is formed. The vertical swing width of the rod 197 is secured.

  In addition, when attaching the balance device 180 to the top surface of the chassis or the top surface of the exterior cover of the main body 111, the balance device 180 can be fixed to the top of the fuselage 110 very easily by applying an adhesive to the bottom surface of the fixing plate 189. Is something that can be done.

  As described above, this helicopter toy 100 is equipped with a balance device 180 in the fuselage 110, and can be freely operated to raise, lower, maintain a predetermined altitude, move forward, retreat, turn, etc. by an operation signal. In the space of the state, it is possible to perform a stable flight and perform a maneuvering operation relatively easily.

  However, the helicopter toy 100 is usually made small and light, and the airframe 110 may swing back and forth or left and right due to slight disturbance such as air convection.

  If the swinging back and forth is skilled in maneuvering operations, the restoration operation can be performed to return to normal flight by the forward or backward control operation, but the left and right shaking can be restored. Therefore, it is difficult to control to prevent the fall and the fall.

  However, the helicopter toy 100 according to this embodiment includes the stabilizer 170 and the balance device 180 as described above. Therefore, when the airframe 110 changes from the normal state shown in FIG. 8A to the inclined state shown in FIG. 8B due to disturbance such as turbulent flow, the support of the balance rod 197 located above the vertical line of the center of gravity of the airframe 110 is supported. The point will deviate from the vertical line. Therefore, in order for the airframe 110 to tilt, a force is required to move the balance rod 197 having the enormous portions 199 at both ends laterally from above the center of gravity of the airframe 110.

  For this reason, the weight of the balance rod 197 becomes resistance to an external force that tilts the airframe 110, and the inclination of the airframe 110 can be reduced.

  Further, as shown in FIG. 8B, even when the airframe 110 is inadvertently tilted due to a disturbance, it can be quickly returned to the normal state shown in FIG.

  That is, when the fuselage 110 is tilted sideways, the stabilizer 170 maintains rotation in the horizontal plane due to rotational inertia, and therefore the upper rotor head 155 connected to the stabilizer head 171 by the link shaft 179 tilts, and the upper rotor head 155 The inclination is reversed every time the upper rotor shaft 153 rotates 180 degrees.

  For this reason, the elevation angle, which is the pitch angle of the upper rotor blade 157, is larger on the inclined side (right side in FIG. 8B) and smaller on the opposite side (left side in FIG. 8B), and the lift F1 generated by the upper rotor 151 is greatly generated on the inclined side. As shown in FIG. 8B, an upward lift F1 ′ is generated so as to restore the inclination.

  In addition, since the balance rod 197 of the balancer 180 is kept horizontal, the triangle formed by both ends of the balance rod 197 and the upper rotor head 155 becomes an unequal triangle, and the upper rotor head 155, which is the center of the lift F1, is balanced with the balance rod. The action of returning to the upper center of 197 can be increased.

  Therefore, as shown in FIG. 8A, the lift F1 by the upper rotor 151, the lift F2 by the lower rotor 161, and the gravity G of the entire body 110 including the balancing device 180 overlap on the vertical line, It is possible to quickly return to a stable state where the center of the upper rotor head 155 is an isosceles triangle.

  In addition, it is not limited to the stability during the flight, and even when starting and taking off, such as when the main rotor 150 is rapidly rotated from the landing state to take off, the aircraft will be affected by the vibration of the airframe 110 at the start of starting the motor and rotor. Even if it swings, the peristalsis can be limited to a small extent, and the right and left tilt can be restored to the stable state by the balancer 180, and the posture immediately after takeoff can be quickly returned to the stable state and the operation can be easily continued.

  As described above, according to the present embodiment, the balance rod 197 can be swung so that the balance rod 197 of the balancer 180 is kept horizontal even when the body 110 is swung from side to side. The enormous parts 199 formed at both ends of the balance rod 197 are not limited to resin, but may be formed of a light metal such as aluminum, reducing the weight of the balancer 180 and reducing the weight increase of the helicopter toy 100. Yes.

  The length L2 of the balance rod 197 is preferably at least approximately equal to the total length L1 of the fuselage 110 or longer than the full length L1 of the fuselage 110 so as to be longer than the full length L1 of the fuselage 110.

  Further, although the balance rod 197 is curved so that the center portion is higher than both ends, when the balance rod 197 is suspended from a support pin 193 having a swing center as shown in FIG. Sometimes.

  The balance rod 197 is not only fixed to the main body 111 so as to be suspended by the support main body 183 such as the fixing plate 189 and the swing support 191 such as the rod support plate 195, but also the main body of the body 110. In some cases, the balance rod 197 is suspended from a chassis or the like built in the 111 so that the balance rod 197 is swingably attached to the upper portion of the main body 111.

That is, while increasing the center position of the balance rod 197 in the balancer 180, the center of gravity of the balance rod 197 is lower than the support point that is the center of swinging, and the balance rod 197 is leveled with both ends of the balance rod 197 at the same height. It would be enough if it could be maintained.

  In addition, the stabilizer 170 is not limited to the case where it is provided above the upper rotor 151. The upper rotor 151 is attached to the upper end of the upper rotor shaft 153, and the stabilizer 170 is located below the upper rotor 151 and above the lower rotor 161. In addition, a stabilizer 170 may be provided between the upper rotor 151 and the lower rotor 161.

  As described above, the helicopter toy 100 according to the embodiment of the present invention is provided with the long balance rod 197 extending to the left and right of the airframe 110 so that the airframe 110 can swing. In some cases, the balance rod 197 having the enormous portion 199 at both ends is kept horizontal, the balance rod 197 holds down the inclination of the airframe 110 to a small extent, and the inclination is quickly restored to enable stable flight.

  In addition, the helicopter toy 100 having the balance rod 197 that can swing the left and right ends up and down at the upper part of the main body 111 keeps the balance rod 197 that is kept horizontal even when the fuselage 110 is tilted at the height of the fuselage 110. Even when flying low near the ground or floor, the balance rod 197 does not hit the obstacle, and even with the balance rod 197 whose ends are curved lower than the center, the aircraft remains in a stable state. Can be attached.

  The helicopter toy 100, in which the main rotor 150 is a counter-rotating rotor of the upper rotor 151 and the lower rotor 161, can easily adjust the direction of the nose by adjusting the rotational speed of the upper rotor 151 and the lower rotor 161 individually. It is also possible to easily turn the nose to change the direction of the nose.

  In addition, the helicopter toy 100, which allows the pitch angle of the upper rotor blade 157 in the upper rotor 151 to be variable and the pitch angle to be adjusted by the stabilizer 170, allows the main rotor 150 to fly back and forth and to the left and right and to stabilize the flight. The flight operation can be facilitated.

  Furthermore, the helicopter toy 100 having the rear rotor 116 horizontally allows the fuselage 110 to tilt forward or backward by rotating the rear rotor 116 forward or backward, and the main rotor 150 allows the nose direction to be changed. The forward and backward movement of the stabilized airframe 110 can be easily controlled with a simple mechanism.

  Even if the balancing device 180 such as the balance rod 197 is light, the length L2 of the balance rod 197 that maintains the level is set to be equal to or greater than the total length L1 of the fuselage 110, so that the width of the fuselage 110 is reduced. The rolling due to can be effectively limited.

  Further, since the balancer 180 supports the balance rod 197 in a swingable manner using a support main body 183 having a flat plate-shaped fixing plate 189, the airframe 110 in the helicopter toy 100 is easily supported by the fixing plate 189. It can be attached and fixed to the upper part of the plate.

  Then, if the support portion 181 of the balancer 180 is the support main body portion 183 and the swing support portion 191 and the center portion of the balance rod 197 is supported by the swing support portion 191, the long balance rod 197 is moved from the support point to the left and right. It can be supported horizontally, while being easily swingable as a symmetry.

  Further, a rod support plate 195 serving as a swing support portion 191 is disposed between the front support plate 185 and the rear support plate 187 of the support body portion 183 so that the rod support plate 195 can swing and a support pin is provided near the upper end thereof. The support portion 181 supported by 193 can reliably suspend the rod support plate 195 and the balance rod 197 so that the rod support plate 195 and the balance rod 197 can swing. The horizontal state of the rod 197 can be easily maintained.

  Then, if the balance rod 197 having the enormous part 199 at both ends of the rod body 198 is curved so that both ends are lower than the center part, the center of gravity position of the balance rod 197 is lower than the center part as the support point of the balance rod 197. In addition, the leveling of the swingable balance rod 197 can be further ensured.

  Further, by making the rod body 198 of the balance rod 197 made of aluminum, the balance rod 197 and hence the balance device 180 can be reduced in weight, and stable flight can be achieved while reducing the weight increase of the helicopter toy 100.

  Furthermore, if the enormous portion 199 is made of a resin pipe that is thicker than the diameter of the rod body 198 of the balance rod 197 and the pipe shaft is horizontal, the balance rod 197 can easily increase the horizontal maintenance force while suppressing an increase in the weight of the balance rod 197. Moreover, it is possible to maintain a stable appearance.

  As described above, the helicopter toy 100 according to the embodiment of the present invention includes the upper rotor 151 and the lower rotor 161 that are counter-rotating rotors, and can be lifted and lowered, suspended in the air, and the like. While having a stabilizer 170 for adjusting the pitch angle to enable stable flight, by providing the balancing device 180, lateral stability can be further enhanced and stable flight can be made easier.
