The propeller toy described in Non-Patent Document 1 includes three wheels, and can run on the running surface by the propulsion force of the propeller by rotationally driving the rotor shaft slightly inclined forward. There is a problem that the traveling speed is slow because the inclination angle of the rotor shaft is small. In addition, if the inclination angle of the rotor shaft is increased, the traveling speed can be increased, but in that case, it becomes difficult to obtain the lift necessary for ascent.
In addition, the propeller toy that is placed on the running surface and is in a stopped state moves when an external force is applied because the wheels are idle, and can be displayed on an inclined surface, for example. It was not a thing. Furthermore, it does not have a mechanism that stops immediately when it lands or when it finishes traveling.

  The present invention has been made in view of such problems of the prior art, and is a propeller toy capable of running and flying, and can adjust the running speed by changing the inclination angle of the rotor shaft. Another object of the present invention is to provide a propeller toy that can be stopped immediately after landing or immediately after running.

  A propeller toy according to the present invention is a propeller toy remotely controlled by an operation signal from a transmitter, and includes a body, a front wheel attached to a front side of the body, and a connecting member pivotally attached to a rear portion of the body. A rear wheel attached to the rear side of the fuselage via the connecting member, a drive motor, a rotor shaft that is attached to protrude above the fuselage and is driven to rotate by the drive motor, and the rotor shaft A rotor mounted on the rotor shaft so as to be orthogonal to the rotation center axis of the vehicle and a braking member projecting downward from the bottom surface of the fuselage so as to contact the running surface in a stationary state. A plurality of members mounted on the fuselage including the rotor, and the fuselage arranged to be vertically movable at least with respect to the rear wheel via the connecting member. The rotor shaft is attached to the rear side with respect to the center of gravity of the floating portion, and the vehicle body is inclined slightly forward by causing the braking member to contact the running surface. In the stopped state, the rotor shaft was driven by the drive motor, and the rear part of the fuselage was floated in a state where the front wheels and the rear wheels were grounded on the running surface. The brake member is configured to start traveling with a forward inclined posture separated from the traveling surface, and to take off and fly by driving the rotor shaft at a higher speed by the drive motor. And

  The propeller toy according to the present invention includes a connecting member pivotally attached to a front portion of the airframe, the front wheel is attached via the connecting member, and the floating portion is connected to the front wheel via the connecting member. The propeller toy is configured to be movable in a vertical direction with respect to the propeller toy, and when the propeller toy is in a traveling state in a forward tilted posture, the rotor shaft is driven at a higher speed by the drive motor. With the rear wheel in contact with the running surface, the front part of the aircraft is levitated, and the aircraft is made to take a substantially horizontal posture with a slight forward tilt, and then is configured to take off and fly. Yes.

  In the propeller toy according to the present invention, an upper rotor and a lower rotor that are rotationally driven in opposite directions are attached to the rotor shaft, and when the propeller toy is in a running state or a flying state, the drive motor The upper and lower rotors are configured to turn left and right by rotating at different speeds.

  Furthermore, this propeller toy is equipped with an elastic member that urges the wheel in a direction to move the wheel downward in the pivotally attached portion of the fuselage and the connecting member, and absorbs an impact when the propeller toy lands. It may be configured as follows.

  In the propeller toy, the rear wheel is preferably formed larger than the front wheel.

  And it is suitable for the front end of the said front wheel to be located in the forefront of the said propeller toy.

  According to the present invention, the propeller toy is capable of running and flying, and the front wheel and the rear wheel are grounded when the rotor shaft is driven by attaching the rear wheel to the airframe via the connecting member. Thus, the tilt angle of the rotor shaft can be changed by floating the rear part of the fuselage, so that it is possible to provide a propeller toy that can adjust the traveling speed by finely adjusting the rotational speed of the rotor. In addition, the propeller toy can be stopped immediately after landing or after traveling by grounding the braking member on the traveling surface. Furthermore, by rotating the rotor of the propeller toy in a stopped state instantaneously at a high speed, it is possible to give a large lift to the propeller toy in a substantially horizontal posture and easily take off. Further, when the braking member is brought into contact with the mounting surface at the time of stopping, even an inclined surface can be easily fixed and exhibited.

  Then, by attaching the front wheels to the airframe via the connecting member, when the propeller toy is in the traveling state in the forward inclined posture, the airframe is in a state where the front wheels and the rear wheels are grounded by increasing the rotational speed of the rotor. The front part can also be lifted, and the aircraft can be shifted to a substantially horizontal posture with a slight forward tilt. Thereby, since a big lift can be obtained instantaneously, the propeller toy in a driving | running | working state can be taken off smoothly.

  In addition, by providing two rotors that can be driven to rotate in opposite directions, it is possible to cancel the reaction torque applied to the airframe to enable stable straight-ahead travel and straight-ahead flight, and during traveling or flight due to the difference in rotational speed It is possible to provide a propeller toy that enables a turning motion by changing the direction of the airframe to the left and right.

  Furthermore, the impact when the propeller toy is landed can be absorbed by attaching the elastic member to the pivot part of the fuselage and the connecting member.

  Moreover, by forming the rear wheel larger than the front wheel, the propeller toy can have a powerful appearance and can easily create a forward leaning posture with the front slightly lowered.

  And by making the front end of the front wheel the leading edge of the propeller toy, when the front end of the propeller toy comes into contact with an obstacle such as a vertical wall, the propeller toy moves up the front wheel and gets over the obstacle Can be made.

  Hereinafter, modes for carrying out the present invention will be described. As shown in FIGS. 1 and 2, the propeller toy 1 is remotely controlled by an operation signal from the transmitter 110. This propeller toy 1 includes a fuselage 10, a front wheel 11 attached to the front side of the fuselage 10, a rear wheel 12 attached to the rear side of the fuselage 10, and a rotor shaft attached so as to protrude above the fuselage 10. 30 and 40, two rotors 3 and 4 attached to the rotor shafts 30 and 40, and a braking member 13 projecting downward from the bottom of the rear portion of the body 10 so as to contact the running surface. Further, inside the fuselage 10, two rotor drive motors 80 (80U, 80L) are mounted on the left and right of the rear part, and also have a battery 90, a control circuit board, and the like.

  The front wheel 11 and the rear wheel 12 are attached to the airframe 10 via connecting members 5 pivotally attached to the front and rear portions of the airframe 10, respectively. The front wheel 11 is arranged such that the front end thereof is the leading edge of the propeller toy 1, and the rear wheel 12 is formed larger than the front wheel 11 and has a powerful appearance.

  The rotor drive motor 80, the rotor shafts 30 and 40, the rotors 3 and 4, the braking member 13, a plurality of members mounted on the body 10 such as the battery 90 and the control circuit board, and a portion including the body 10 (hereinafter referred to as “ The floating portion is referred to as “movable up and down” with respect to the wheel via the connecting member 5, and the rotor shafts 30 and 40 are attached to positions slightly behind the center of gravity of the floating portion. Therefore, when the propeller starts rotating, as shown in FIG. 6, the rear part of the airframe 10 floats around the axle of the front wheel 11 as a turning shaft, and the vehicle travels forward with a relatively large forward leaning posture. You can drive at speed.

  Next, if the rotation speed of the propeller is increased, the upward force becomes stronger, and as shown in FIG. 7, the front of the floating portion rises and the inclination angle of the rotor shafts 30, 40 becomes smaller, so that the rotor shaft 30 and 40 can be taken off easily. Can do. At this time, by attaching the rotor shafts 30 and 40 to a position slightly behind the center of gravity of the propeller toy 1 including the rotor shafts 30 and 40 and the wheels, the propeller toy 1 is slightly attached to the rotor shaft 30 at the time of flight. , 40 can be made to fly forward with a forward leaning posture inclined forward.

  The rotor shafts 30 and 40 are composed of a coaxial upper rotor shaft 30 and a lower rotor shaft 40 that are rotationally driven in opposite directions. The lower rotor shaft 40 is formed in a cylindrical shape that is rotationally driven by a lower rotor drive motor 80L. Further, the upper rotor shaft 30 penetrates the inside of the lower rotor shaft 40, the upper portion is formed with a large diameter and the lower portion is formed with a small diameter, and the lower diameter shaft portion of the lower portion of the upper rotor shaft 30 is inserted into the lower rotor shaft 40 The lower end of the lever is rotationally driven by the upper rotor drive motor 80U. That is, the upper and lower rotor shafts 30 and 40 are individually rotated and driven via the gears by the two rotor drive motors 80 (80U and 80L) disposed in the body 10.

  The upper and lower rotors 3 and 4 are attached so as to be orthogonal to the rotation center axes of the rotor shafts 30 and 40, respectively. That is, the propeller toy 1 is a counter-rotating propeller toy 1 in which the upper and lower rotors 3 and 4 are rotationally driven in directions opposite to each other.

  The braking member 13 is made of a material such as a resin having a high friction coefficient, and is in contact with the traveling surface when the vehicle is stopped. Thereby, since the propeller toy 1 can be prevented from moving unexpectedly, the propeller toy 1 can be easily fixed and displayed on a mounting surface such as an inclined surface. Furthermore, the propeller toy 1 can be stopped immediately after landing or after the traveling is finished by bringing the braking member 13 into contact with the traveling surface.

  The propeller toy 1 is provided with a torsion coil spring as an elastic member that urges the front wheel 11 and the rear wheel 12 in a direction in which the front wheel 11 and the rear wheel 12 are moved downward at a pivotal attachment portion of the airframe 10 and the connecting member 5. For this reason, an impact can be absorbed when the propeller toy 1 is landed.

  With the configuration as described above, as shown in FIG. 5, the propeller toy 1 is in a stopped state in which the body 10 is slightly inclined forward and the braking member 13 is grounded to the running surface. When the rotor shafts 30 and 40 are driven by the rotor drive motor 80, the center of gravity of the floating portion is positioned slightly forward with respect to the rotor shafts 30 and 40, as shown in FIG. The rear part of the body 10 can be lifted with the front wheels 11 and the rear wheels 12 in contact with the running surface.

  Since the propeller toy 1 assumes a forward tilt posture in which the grounded braking member 13 is separated from the traveling surface, the propeller toy 1 can start traveling by the propulsive force generated by the rotation of the rotors 3 and 4.

  When the propeller toy 1 is in a traveling state in which the propeller toy 1 is in the forward leaning position, when the rotor shafts 30 and 40 are driven at a higher speed by the rotor driving motor 80, as shown in FIG. The front part of the airframe 10 can also be levitated in a state where 12 is in contact with the traveling surface. In other words, by tilting the fuselage 10 back to the horizontal direction and shifting it to a substantially horizontal posture slightly tilted forward, a large lift can be obtained instantaneously, so the propeller toy 1 in the running state can be It can be taken off smoothly.

  Since the propeller toy 1 employs the counter-rotating rotors 3 and 4, the propeller toy 1 can cancel the reaction torque applied to the airframe 10 and perform stable straight traveling and straight flight. Further, when the propeller toy 1 is in a running state or a flying state, the upper and lower rotors 3 and 4 can be turned left and right by rotating at different speeds by the rotor drive motor 80.

  In addition, by making the Aircraft 10 imitating a car body such as a racing cart or buggy, the rotors 3 and 4 in a stationary state are instantaneously rotated at high speed and stopped immediately to produce a jump action on the Aircraft 10. It can also be made.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external perspective view of the propeller toy 1 and the transmitter 110 in the present embodiment, and FIG. 2 is a schematic side view showing the internal structure of the propeller toy 1 in the present embodiment. In the present invention, “front”, “rear”, “left”, “right”, “upper”, and “lower” follow the direction of the propeller toy as viewed forward.

  As shown in FIG. 1, the propeller toy 1 according to the present invention travels and flies according to the signal received by the receiver by transmitting a wireless operation signal from the transmitter 110 to the receiver built in the body 10. This is a remotely controlled propeller toy 1.

  The shape of the propeller toy 1 will be described with reference to FIGS. 1 and 2. The propeller toy 1 is made of, for example, a lightweight material such as molded polystyrene foam or plastic. The propeller toy 1 includes a body 10 that is shaped like a racing cart. A pair of front wheels 11 are attached to the front side of the body 10 and a pair of rear wheels are mounted on the rear side of the body 10. 12 is installed. The front wheel 11 is arranged such that the front end thereof is the leading edge of the propeller toy 1, and the rear wheel 12 is formed larger than the front wheel 11 and has a powerful appearance. The front wheels 11 and the rear wheels 12 have a surface with a low coefficient of friction and are mounted on the axle so as to be freely movable. The propeller toy 1 is a small toy having a total length, a total width and a total height of about 100 to 200 mm. Note that the size of the propeller toy 1 is not limited to the above.

  Rotor shafts 30 and 40 are attached to the body 10 so as to protrude upward. The rotor shafts 30 and 40 are mounted with upper and lower rotors 3 and 4 which are rotors of the propeller toy 1. Inside the fuselage 10, two rotor drive motors 80 (80U, 80L) are mounted on the left and right of the rear part, and also have a battery 90, a control circuit board, and the like.

  The rotor shafts 30 and 40 include an upper rotor shaft 30 and a lower rotor shaft 40 that are coaxially driven to rotate in opposite directions. The lower rotor shaft 40 is formed in a cylindrical shape and has a lower rotor gear 41 in the vicinity of the center. The lower rotor gear 41 is meshed with the pinion gear 81L of the lower rotor drive motor 80L. Therefore, when the lower rotor drive motor 80L is driven, the lower rotor shaft 40 is rotationally driven.

  The upper rotor shaft 30 penetrates the inside of the lower rotor shaft 40, and is formed with a large diameter at the top and a small diameter at the bottom. The upper rotor shaft 30 has a lower small-diameter shaft portion penetrating the lower rotor shaft 40, and the upper rotor gear 31 arranged at the lower end thereof meshes with the pinion gear 81U of the upper rotor drive motor 80U. Has been. Therefore, when the upper rotor drive motor 80U is driven, the upper rotor shaft 30 is rotationally driven. In other words, the upper and lower rotor shafts 30, 40 are individually connected via the gears 31, 41, 81U, 81L by the two rotor drive motors 80 (80U, 80L) disposed on the left and right of the rear part of the body 10. Driven by rotation.

  The upper and lower rotors 3 and 4 are respectively attached so as to be orthogonal to the rotation center axis of the rotor shafts 30 and 40. That is, the rotational power of the rotor drive motor 80 is transmitted to the upper and lower rotors 3 and 4 via the rotor shafts 30 and 40. Further, the blades of the upper and lower rotors 3 and 4 are formed so as to incline forward with respect to the respective rotation directions. That is, the propeller toy 1 is a counter-rotating propeller toy 1 in which the upper and lower rotors 3 and 4 are rotationally driven in directions opposite to each other. Accordingly, the reaction torque applied to the airframe 10 can be canceled by rotating the rotors 3 and 4 in the opposite directions. Further, by adjusting the rotational speed of the rotors 3 and 4 by increasing or decreasing one of the rotational speeds, the airframe 10 can be caused to make a turning motion.

  The rotor shafts 30 and 40 include a plurality of members and airframes mounted on the airframe 10, such as the rotor shafts 30 and 40, the rotors 3 and 4, the braking member 13, the rotor drive motor 80, the battery 90, and the control circuit board. It is attached to a position behind the center of gravity of the floating portion that includes 10 and slightly behind the center of gravity of the entire propeller toy 1 including the wheels 11 and 12. That is, the center of gravity position of the entire propeller toy 1 is located behind the center of gravity of the floating portion.

  In this way, by arranging the rotor shafts 30 and 40 on the rear side with respect to the center of gravity of the floating portion, the front wheel 11 and the rear wheel 12 that are attached to the connecting member 5 described later when lift is applied to the airframe 10 The rear part of the airframe 10 can be levitated while being in contact with the running surface. Further, by arranging the rotor shafts 30 and 40 slightly behind the center of gravity of the entire propeller toy 1, the propeller toy 1 slightly tilts the rotor shafts 30 and 40 forward during flight. It is possible to fly forward by leaning forward.

  In addition, since the rear wheel 12 is formed larger than the front wheel 11, the center of gravity position of the propeller toy 1 as a whole can be made closer to the rotor shafts 30 and 40 compared to the center of gravity of the floating portion, so that As described above, the propeller toy 1 can be made to perform a stable flight at a low speed by easily creating a forward leaning posture in which the rotor shafts 30 and 40 are slightly tilted during flight.

  The stabilizer 7 is a round bar-shaped member that is pivotally attached to the upper rotor shaft 30 below the upper rotor 3 that is pivotally attached to the upper rotor shaft 30 and can be tilted. It is mounted so as to be about 30 to 90 degrees. The stabilizer 7 has weights 76 attached to both ends. In addition, a stabilizer link 78 is attached to the stabilizer 7 so that the stabilizer 7 and the upper rotor 3 are interlocked.

  That is, when the stabilizer 7 is tilted in a certain direction around the axis that supports the stabilizer 7, the upper rotor 3 is centered on the axis that supports the upper rotor 3 via the stabilizer link 78 along with the inclination. The blades of the upper rotor 3 are tilted in the same direction. For this reason, even if the fuselage 10, the rotor shaft 30, 40, etc. are swung by disturbances such as wind, the stabilizer 7 maintains its rotation and keeps the upper rotor 3 at a constant pitch angle with respect to the horizontal. Therefore, it is possible to fly the aircraft 10 stably.

  Further, the propeller toy 1 includes a braking member 13 projecting downward from the rear bottom surface of the airframe 10. The braking member 13 is made of a material such as a resin having a high friction coefficient, and is in contact with the traveling surface in a stationary state. Thereby, when the propeller toy 1 is in a stationary state on the traveling surface, the braking member 13 is in contact with the traveling surface so that the frictional force between the traveling surface and the traveling surface resists the force in the direction parallel to the traveling surface. Therefore, the propeller toy 1 does not move unexpectedly due to external force. Further, the propeller toy 1 can be easily fixed on a mounting surface such as an inclined surface for display. Further, the braking member 13 can be used as a brake. That is, if the player performs a traveling stop operation while the propeller toy 1 is traveling on the traveling surface, the airframe 10 can be immediately stopped by bringing the braking member 13 into contact with the traveling surface. Similarly, if the landing operation is performed during the flight of the propeller toy 1, the airframe 10 can be immediately stopped by bringing the braking member 13 into contact with the traveling surface after landing.

  The front wheel 11 and the rear wheel 12 attached to the airframe 10 are attached to the airframe 10 via a front connecting member 5a and a rear connecting member 5b pivotally attached to the front and rear portions of the airframe 10, respectively. Specifically, the connecting member 5 is pivotally attached in the vicinity of one end portion on the side of the body 10, and an axle is attached to the other end portion of the connecting member 5. That is, the floating portion is arranged to be movable up and down via the front connecting member 5a and the rear connecting member 5b corresponding to the front wheel 11 and the rear wheel 12, respectively. The connecting member 5 is formed with a locking bar 20 that extends further inward from the body 10 side from the pivotally attached portion. The locking bar 20 engages with an upper locking piece 21 and a lower locking piece 22 that are fixed to the airframe 10 so as to protrude to the connecting member 5 side, thereby limiting the rotation range of the connecting member 5. To do.

  A torsion coil spring (not shown) as an elastic member that biases the front wheel 11 and the rear wheel 12 in the direction of moving downward is wound around the connecting portion 5 and the pivot portion of the body 10. In other words, when the propeller toy 1 is placed on the running surface, as shown in the drawing, the aircraft body 10 is in a state where it is sunk by its own weight against the elastic force of the elastic member, and the lower side When the stop piece 22 and the locking bar 20 are engaged, the connecting member 5 is in a substantially horizontal state. At this time, as described above, the braking member 13 is in contact with the traveling surface.

  When the fuselage 10 floats due to the rotation of the rotors 3 and 4, the front wheels 11 and the rear wheels 12 are moved downward with the axis of the pivot part as the rotation center due to the elastic force of the elastic members and the weight of the front wheels 11 and the rear wheels 12 To turn.

  When the propeller toy 1 is landed, if the body 10 sinks downward, the elastic member functions as a cushion and can absorb the impact.

  The propeller toy 1 incorporates in the body 10 a receiver having a control unit that controls the operation of the rotor drive motor 80 based on an operation signal from the transmitter 110, a battery 90 that supplies power to each unit, and the like. ing. Thereby, the propeller toy 1 causes the control unit of the receiver in response to the remote operation signal from the wireless transmitter 110 to generate a predetermined control signal and drive the rotor drive motor 80 (80U, 80L), Run, jump, climb, descend, turn and advance.

  The control unit is not limited to being formed as a part of the receiver, and can be provided separately from the receiver. However, by forming the control unit integrally with the receiver, a small and simple propeller can be provided. The toy 1 can be configured.

Next, the transmitter 110 and the receiver 100 of the present embodiment will be described with reference to FIGS. FIG. 3 is a front view of the transmitter 110 in the present embodiment, and FIG. 4 is a functional block diagram of the propeller toy 1 in the present embodiment.
The transmitter 110 is held by a player who remotely controls the propeller toy 1 and transmits an operation signal to the receiver 100 in the machine body 10.

  The transmitter 110 includes an accelerator lever 120, a turning lever 124 and a trim adjustment dial 122, which are operation units for controlling the rotational speed of the rotors 3 and 4, and an antenna 116 for transmitting an operation signal. The transmitter 110 includes a control unit 112 that generates a predetermined signal in response to a player's operation, a transmission circuit 111 that modulates an encoded signal transmitted from the control unit 112, an amplifier 118, A power supply (not shown) is incorporated.

  The antenna (infrared oscillator) 116 is mounted on the upper surface of a hollow, substantially rectangular parallelepiped main body case. The accelerator lever 120 and the turning lever 124 are disposed in front of the main body case, and a trim adjustment dial 122 is disposed in the vicinity of the turning lever 124. A power switch, an indicator, and the like are also provided on the front surface of the transmitter 110.

  The accelerator lever 120 can be tilted up and down, and controls the two upper and lower rotor drive motors 80U and 80L (80) for rotationally driving the rotors 3 and 4 at the same rotational speed. The upper rotor 3 and the lower rotor 4 are rotated. The accelerator lever 120 can be tilted upward to increase the rotational speed of each motor 80, and can be tilted downward to decrease the rotational speed of each motor 80. Further, the accelerator lever 120 can be stopped to drive each motor 80 by tilting to the lower end position. That is, the accelerator lever 120 is an operation unit for instructing the propeller toy 1 to travel, jump, ascend, descend, and advance flight.

  The swivel lever 124 can be tilted left and right, and controls the upper and lower rotor drive motors 80U, 80L (80) so as to make a difference in rotational speed between the upper rotor 3 and the lower rotor 4, thereby Turn. By tilting the swivel lever 124 to the left or right, the propeller toy 1 can change the direction of the airframe 10 to the left or right so that the swivel motion can be performed. That is, the turning lever 124 is an operation unit for instructing turning traveling and turning flight.

  The trim adjustment dial 122 controls the electric power supplied to the upper and lower rotor drive motors 80U and 80L (80) to equalize the rotational speeds of the upper rotor 3 and the lower rotor 4, thereby moving forward or flying forward. This is an operation unit for stably propelling the propeller toy 1 during operation.

  The rotational speeds of the rotors 3 and 4 are linearly controlled by variable resistances in the accelerator lever 120, the turning lever 124, and the trim adjustment dial 122 of the transmitter 110.

  Then, as shown in FIG. 4, the receiver 100 receives a radio signal transmitted from the transmitter 110 via the antenna 106 and demodulates the received circuit 101, and decodes the demodulated signal to drive the rotor. A control unit 102 that generates a control signal for driving the motor 80 and a power source (not shown) are provided. Note that it is preferable that the transmitter 110 and the passive elements of the receiver circuit 101 of the transmitter 110 and the receiver 100 are detachable crystal resonators so that the frequency can be changed by the player.

  Accordingly, if an operation command for increasing the rotational speed of the rotors 3 and 4 is transmitted by operating the accelerator lever 120, the rotor drive motor 80 is driven to rotate the upper and lower rotors 3 and 4 at a predetermined speed. it can. The propeller toy 1 placed on the running surface can be run by rotating the rotors 3 and 4 at a predetermined speed, and can be taken off and raised by further increasing the rotational speed. Further, when the propeller toy 1 is in a running state or a flying state, the upper and lower rotors 3 and 4 are operated so that the rotational speeds of the upper and lower rotors 3 and 4 are slightly different by operating the turning lever 124 and transmitting a turning operation command. The drive motors 80U and 80L (80) for the rotor can be controlled. By applying torque caused by the difference in rotational speed between the upper and lower rotors 3 and 4 to the airframe 10, the propeller toy 1 can perform a turning motion so as to change the direction of the nose to the left or right.

  Then, if an operation command for operating the accelerator lever 120 to reduce the rotation speed of the rotors 3 and 4 is transmitted, the propeller toy in the running state is driven by decelerating the upper and lower rotor drive motors 80U and 80L (80). 1 can be decelerated and the propeller toy 1 in flight can be lowered. Further, by operating the accelerator lever 120 to tilt to the lower end position, the upper and lower rotor drive motors 80U, 80L (80) are stopped, the propeller toy 1 in the running state is stopped, and the flying state is entered. A certain propeller toy 1 can be landed on the running surface.

  Furthermore, after the accelerator lever 120 is instantaneously tilted upward, the propeller toy 1 can be caused to produce a jump action by performing an operation of tilting downward.

Hereinafter, the traveling and flight procedures and operations of the propeller toy 1 will be described with reference to FIGS.
First, the power switch provided on the side surface of the machine body 10 is turned on, and the propeller toy 1 is placed on the running surface as shown in FIG. At this time, the propeller toy 1 is in a stopped state in which the braking member 13 is brought into contact with the traveling surface and the body 10 is in a substantially horizontal posture in which it slightly tilts forward. Next, when the power switch of the transmitter 110 is turned on and the accelerator lever 120 is tilted upward to a predetermined position, the rotor shafts 30 and 40 are driven by the rotor drive motor 80, and the rotors 3 and 4 are rotated. Lift is generated. When lift is generated, the center of gravity of the floating portion is located in front of the rotor shafts 30 and 40, and the rear wheel 12 is connected to the airframe 10 via the rear connecting member 5b. In addition, with the front wheels 11 and the rear wheels 12 in contact with the traveling surface, the rear portion of the airframe 10 rises with the axle of the front wheels 11 as the rotation axis. The propeller toy 1 assumes a forward leaning posture in which the grounded braking member 13 is separated from the traveling surface, and thus starts traveling by the propulsive force generated by the rotation of the rotors 3 and 4. At this time, since the propeller toy 1 travels forward in a forward tilt posture in which the rotor shafts 30 and 40 have a relatively large inclination angle, the propeller toy 1 can travel at a high traveling speed.

  When the rear part of the airframe 10 floats, the locking bar 20 of the rear connecting member 5b engages with the upper locking piece 21 to limit the flying height of the rear part of the airframe 10.

  Then, when the propeller toy 1 is in a traveling state in which the propeller toy 1 is in a relatively large forward tilting posture, if the operation of tilting the accelerator lever 120 to a predetermined position further upward is performed, the rotational speed of the rotors 3 and 4 is increased. Large lift is generated. When the lift increases, as shown in FIG. 7, the front portion of the body 10 also floats with the front wheels 11 and the rear wheels 12 in contact with the traveling surface. In other words, the propeller toy 1 has its front part lifted so that the airframe 10 is returned to the horizontal direction by this upward floating force (that is, so that the inclination angle of the rotor shafts 30 and 40 is reduced), It shifts to a substantially horizontal posture that is inclined forward.

  When the front part of the airframe 10 floats, the locking bar 20 of the front connecting member 5a is engaged with the upper locking piece 21 to limit the flying height of the front part of the airframe 10.

  Further, when the propeller toy 1 is in a traveling state in which the propeller toy 1 is in a forward inclined posture (see FIG. 6) or a substantially horizontal posture (see FIG. 7), if the turning lever 124 is operated, the two rotor drive motors 80 The motor 80 is driven so as to cause a difference in rotational speed, and a turning force that turns the body 10 left and right is generated. Here, since the wheel surface that contacts the running surface is processed with a low friction coefficient, the wheel slides on the running surface. That is, when the turning force is generated, the propeller toy 1 travels in the turning direction by the propulsive force while changing the nose in the left-right direction.

  When the propeller toy 1 is in a traveling state in a substantially horizontal posture, if the operation of tilting the accelerator lever 120 further upward is performed, the rotational speed of the rotors 3 and 4 increases. At this time, since the airframe 10 is in a substantially horizontal posture, a large lift is instantaneously generated in the propeller toy 1.

  That is, when the propeller toy 1 is in a stopped state placed on the running surface, if the accelerator lever 120 is gradually tilted upward, the propeller toy 1 starts running and the rotor shafts 30, 40 are relatively After accelerating to a forward leaning posture with a large inclination angle, the rotor shafts 30, 40 can take off smoothly and take off in a substantially horizontal posture with a small inclination angle. And, since the propeller toy 1 in the flight state is mounted at a position where the rotor shafts 30 and 40 are slightly rearward with respect to the center of gravity of the entire propeller toy 1, the rotor shafts 30 and 40 are slightly forward. It will move forward in a tilted forward leaning posture. In addition, the propeller toy 1 in the flying state is maintained in a stable posture by the stabilizer 7.

  Then, when the propeller toy 1 is in a flying state, the player operates the accelerator lever 120 of the transmitter 110 to bring the rotors 3 and 4 to a predetermined rotational speed, so that the lift obtained by the rotors 3 and 4 And the gravity applied to the airframe 10 can be balanced to cause the propeller toy 1 to perform a horizontal flight, and by further reducing the rotation speed, the airframe 10 can be lowered and landed.

  Further, when the propeller toy 1 is in a flying state, the rotation speeds of the upper rotor 3 and the lower rotor 4 are controlled by operating the turning lever 124 so that the upper and lower rotors 3 and 4 are rotated at different speeds. By changing to a slightly different speed, the propeller toy 1 can change the direction of the nose. Accordingly, when the propeller toy 1 is in the forward flight state and receives the turning operation command, the propeller toy 1 performs the turning flight while the nose direction is changed during the forward flight.

  Further, when the propeller toy 1 is in a running state, the propeller toy 1 can be made to produce a jump action by performing an operation of quickly tilting the accelerator lever 120 upward and returning it immediately downward.

  Further, when the propeller toy 1 is in the stopped state, if the accelerator lever 120 is quickly tilted upward, the lift force necessary for ascending from the rotors 3 and 4 in the substantially horizontal state is obtained before the forward tilting posture is achieved. It is also possible to take off the aircraft 10 and immediately shift to the flying posture.

  When the propeller toy 1 is traveling on the traveling surface, if the traveling stop operation is performed, the aircraft 10 that has lost its buoyancy sinks due to its own weight, and the braking member 13 comes into contact with the traveling surface. Will stop. Similarly, if the landing operation is performed during the flight of the propeller toy 1, the brake member 13 comes into contact with the traveling surface after landing, so the aircraft 10 immediately stops.

  As described above, the propeller toy 1 of the present invention attaches the rear wheel 12 to the airframe 10 via the rear connecting member 5b, thereby grounding the front wheel 11 and the rear wheel 12 when the rotor shafts 30, 40 are driven. In this state, the tilting angle of the rotor shafts 30 and 40 can be changed by floating the rear part of the body 10, so that the traveling speed can be adjusted by finely adjusting the rotational speed of the rotors 3 and 4. In addition, the propeller toy 1 can be stopped immediately after landing or after traveling by bringing the braking member 13 into contact with the traveling surface. Further, by instantaneously rotating the rotors 3 and 4 of the propeller toy 1 in a stopped state at high speed, the propeller toy 1 in a substantially horizontal posture can be given a large lift and can be easily taken off. In addition, when the braking member 13 is grounded to the placement surface when stopped, the propeller toy 1 can be displayed with easy fixing even on an inclined surface.

  Then, by attaching the front wheel 11 to the airframe 10 via the front connecting member 5a, the front wheel 11 and the propeller toy 1 can be increased by increasing the rotational speed of the rotors 3 and 4 when the propeller toy 1 is in the traveling state in the forward inclined posture. With the rear wheel 12 in contact with the ground, the front portion of the body 10 can also be lifted, and the body 10 can be shifted to a substantially horizontal posture with a slight forward tilt. Accordingly, since a large lift can be obtained instantaneously, the propeller toy 1 in the running state can be smoothly taken off.

  In addition, by providing two rotors 3 and 4 that can be driven to rotate in opposite directions, it is possible to cancel the reaction torque applied to the airframe 10 to enable stable straight traveling and straight flight, and due to the difference in rotational speed. It is possible to provide the propeller toy 1 that enables a turning motion during traveling or in flight.

  Furthermore, by attaching an elastic member to the pivoting portion of the airframe 10 and the connecting member 5, the impact when the propeller toy 1 lands can be absorbed.

  Further, by forming the rear wheel 12 larger than the front wheel 11, the propeller toy 1 can have a powerful appearance and can easily create a forward leaning posture with the front slightly lowered.

  And by making the front end of the front wheel 11 the most advanced of the propeller toy 1, when the front end of the propeller toy 1 comes into contact with an obstacle such as a vertical wall, the front wheel 11 rises while rotating and gets over the obstacle The action can be made to propeller toy 1.

  And this invention is not limited to the above Example, A change and improvement are possible freely in the range which does not deviate from the summary of invention. For example, the connecting member 5 of the propeller toy 1 is not limited to being attached to each of the front wheel 11 and the rear wheel 12, and may be attached only to the rear wheel 12. In this case, by gradually increasing the rotational speed of the rotors 3 and 4, it is possible to travel on the traveling surface at a high speed, and by instantaneously rotating the rotors 3 and 4 of the propeller toy 1 in a stopped state. The propeller toy 1 in a substantially horizontal posture can be easily taken off by giving a large lift.

  Then, the transmitter 110 and the receiver 100 may be steerable by connecting them with a cable. Further, the propeller toy 1 is not limited to the case where the airframe 10 simulates a racing car, and the airframe 10 may be formed by imitating various automobiles such as buggies, airplanes, and helicopters. Furthermore, the rotors 3 and 4 are not limited to the twin-rotor type of coaxial reversal type, but are a tandem rotor type having rotors before and after the fuselage 10, and a single rotor and a single rotor having a tail rotor that counteracts the reaction force of this rotor. A rotor type may be adopted. The wheels are not limited to four wheels, and may be a propeller toy 1 such as a three-wheeled motorcycle or a three-wheeled vehicle having the front wheel 11 or the rear wheel 12 as one wheel.
