DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aircraft toy in which the rolling and yawing directions during flight are stabilized.

[0002]

2. Description of the Related Art An airplane toy is made as a miniature version of an ordinary airplane generally used for passenger transportation and the like. Therefore, regardless of the flight performance as to whether or not it can be suspended in the air, a shape having a fuselage, a main wing, a horizontal tail, and a vertical tail is generally used. Of course, the main wing is used to obtain the main lift, the horizontal and vertical tails are provided for flight stability, and in particular, the vertical tail is used to obtain the rolling stabilization function. It is generally known that

[0003]

However, in the case of the airplane toy having the known shape described above, the size and mounting position of the vertical tail are determined according to the size of the fuselage in order to exhibit the function as the vertical tail. For example, it has been pointed out that various restrictions are imposed on the design of the body shape.

[0004] Airplane toys in which the tail fin is omitted, for example, in the form of a UFO (unidentified flying object) are actually sold as toys, but they generally fly even if they are thrusted by human power. It is not envisaged, but simply provides a miniature version of an airplane as a toy for children. Therefore, it cannot actually fly to some extent in the air, and if it is thrown in the air to fly, it will immediately fall.

[0005] As described above, various shapes of an airplane toy can be assumed if the flight performance is neglected. However, in order to secure a certain level of flight performance, the tail fin, particularly the vertical tail fin, cannot be omitted. In this case, flight stability is lost, and the commercial value of an airplane toy on the assumption that flight performance can be expected is impaired.

[0006] The present invention takes into account the above-mentioned problem of restrictions due to the shape of the conventional airplane toy, and eliminates the vertical tail or the horizontal tail or the fuselage without losing flight performance stability. It is an object to provide an airplane toy that can adopt various shapes as a possible airplane toy.

[0007]

SUMMARY OF THE INVENTION The present invention provides a means for solving the above-mentioned problems, which comprises an airframe integrating a wing, a fuselage and a horizontal tail wing, or the latter two parts, and from the center of gravity of the airframe or the front end of the wing on the airframe centerline. Place the rotating rotor within a distance range of a predetermined ratio of the main wing width so that its rotation center is parallel to the main wing, and
Gyroscope precession by the aircraft is Rollin
In the direction to cancel the rotation due to yaw and yaw displacement.
It was an airplane toy that was rotatably mounted to match the correct direction .

The airplane toy of the above construction does not have a vertical tail, but instead has a rotating rotor provided at a predetermined distance from the center of gravity of the aircraft or the front end of the wing on the fuselage centerline. Since the vertical tail can be omitted, the shape of the fuselage can be modified in various ways, and the horizontal tail can be integrated with the fuselage.

The rotating rotor can be provided with a rotating force in various ways. For example, a thrust may be given by a tapping force at the same time as the rotary rotor is hit, or rotation and thrust may be given simultaneously by blowing compressed air to the rotary rotor. or,
The rotational force and the thrust may be applied by different methods or means. For example, a motor is provided in the body, and the rotating rotor is rotated by the motor. Thrust is a method of flying the entire airplane toy horizontally by hand.

The rotating rotor is provided rotatably about a rotation axis parallel to the blade length direction of the main wing. The rotating rotor ensures flight stability in place of the vertical tail,
Flight stability can be obtained by precession of the gyroscope acting on the rotating rotor. Therefore, the rotating rotor must be given a direction of rotation such that this precession acts in a direction that counteracts the rolling and yawing movements that impair flight stability.

The airplane toy of the present invention, which does not have a vertical tail, has a nose that flies in a direction irrelevant to the direction of the airflow, resulting in an imbalance in lift, and the centerline of the airframe over the entire airframe. When the rotating rotor is rotating around an axis parallel to the main wing at this time, the gyroscope's force is set about an axis orthogonal to the respective center lines of the rotating rotor and the fuselage. Differential motion occurs.

If the rotating rotor is rotated in advance so that the direction of rotation of the precession of the gyroscope matches the direction of canceling the rotation of the body due to rolling and the direction of correcting the yaw deviation, the body becomes stable. It is possible for a flight to take place.

[0013] As the airframe shape capable of obtaining the above flight stability, the airframe of the first invention may be formed from the main wing and the fuselage or both integrally as in the second invention. .

When giving rotation to the above-mentioned rotating rotor,
At the center of the fuselage, a hollow tube whose front end extends to the front of the rotating rotor is attached so that the rotating rotor is rotated by air blown from the front end outlet, and the rear end is provided so as to protrude or separate from the horizontal tail. Can be. If this hollow tube is formed of a plastic straw, it is lightweight, and air can be blown from the rear-end blowing port to impart rotation to the rotating rotor.

In the above configuration, flight stability is premised on linear flight. However, flight stability is not necessarily limited to linear flight, and may be curved, for example, so-called boomerang flight. However, in this case, an auxiliary flap is provided on the main wing, and the left and right sides of the auxiliary flap are deformed upside down so that the flight becomes curved.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing an embodiment of an airplane toy, and shows not only the airplane toy but also a launch pad for flying the airplane toy.

As shown in FIG. 1, an airplane toy A comprises a main wing 1, a fuselage 2, and a horizontal tail 3, and a rotary rotor 4 is rotatably provided at a position within a predetermined distance from the front end of the main wing 1 on the fuselage center line. ing. The main wing 1, the fuselage 2, and the horizontal tail 3 are formed independently, and no vertical tail is provided.

The position in the predetermined range is the center of gravity of the aircraft or a position slightly closer to the front end of the main wing. The center of gravity of the aircraft is generally located at a distance of about 1/3 of the width of the main wing from the front end of the main wing. However, it is preferable that the center of gravity be provided slightly before that considering the rotational resistance of the rotary rotor 4.

The main wing 1 has a thin plate shape perpendicular to the fuselage 2 (FIG. 2 (a)). However, as shown in FIG. Alternatively, as shown in FIG. 5, the blade may be of a swept-wing type in which the tip of the blade retreats rearward at a predetermined angle (a). Further, as shown in FIG. 5B, both wings may have a dihedral angle of a predetermined angle.

The rotating rotor 4 has a rotating shaft 4a whose main wing 1
Are mounted rotatably by bearings 5 in parallel with the blade length direction. A notch 6 is provided at the front end of the main wing 1 around the center line of the fuselage to provide the rotating rotor 4,
The rotary rotor 4 is mounted in the notch 6. Although not shown, a thin hook-and-loop fastener may be attached to the outer periphery of the rotating rotor 4. This is to increase game competitiveness as a playground equipment, as described later.

FIG. 1 also shows a perspective view of the launch pad B. The launch table B has a U-shaped launch board 11 on which a suppressor plate 12 is mounted, and as shown by a dashed line in FIG. , In the direction of arrow f in the figure. Launch board 11
A gripping portion 13 is fixed to the lower surface of the device, and a claw plate 14 that overlaps from the back surface to the upper surface is swingably locked.
The claw plate 14 is formed in a fork shape with a notch 14a provided at the tip, and a locking step 14b is provided on the back surface of the tip.

A spring plate 15a is provided at the upper end of a lever 15 that is rotatable about a point P in order to apply a resilient force F to the body, which is locked to the claw plate 14. The claw plate 14 has a mounting base loosely mounted, and can swing freely as shown by a two-dot chain line in FIG.

When the toy A is mounted on the launch pad B and fired, the main wings 1 and 1 are inserted between the launch board 11 and the restraint plate 12 of the launch pad B, and the lever 15 is moved in the direction of the dashed line arrow in FIG. 4 to press the upper portion of the spring plate 15a against the claw plate 14.
When the lever 15 is pulled into the notch 14a of the lifting claw plate 14 in the solid line shape of (b), the shoulder portion of the spring plate 15a is hooked on the locking step portion 14b even if the lever 15 is then pulled in the direction of the solid line arrow in FIG. I ca n’t miss it.

Pulling the lever 15 more strongly, the spring plate 15
When a is curved, the elastic force F is applied to the spring plate 1 at the moment when the shoulder is released.
5a, the user rotates the rotary rotor 4 in the direction of the arrow in FIG. 1 by hitting the rotary rotor 4 of the airplane toy A, and flies in the forward direction by the applied thrust.

When the airplane toy A having the above configuration is fired by the launch pad B, the airplane toy A flies as follows. FIG. 6 is an explanatory diagram of the flight action. (A) As shown in the drawing, when the rotary rotor 4 is hit with the spring plate 15a, a thrust in the direction of arrow F is given and the rotary rotor 4 is rotated. This rotation direction rotates clockwise when the aircraft is viewed from the left side.

When the above-described thrust and rotation are given,
(B) As shown in the figure, near the center line of the fuselage where the rotating rotor 4 is provided, the speed of the airflow arriving above the rotating rotor 4 is large due to the influence of the rotation of the rotating rotor 4, and the speed is small at the lower side. This causes lift. Of course, at the same time, the lift generated by the airflow arriving at the main wing 1 also acts.

The toy A having sufficient lift in this way flies in the direction urged by the launch pad B. At this time, the toy A flies in the predetermined direction without the vertical tail. This is for the following reasons.

If it is assumed that the toy A shown in FIG. 1 flies by receiving a wind from the right side in the traveling direction, the counterclockwise direction when the center line of the airframe as shown in the figure is viewed in the traveling direction. The force in the rolling direction acting as the direction acts. Then, the rotating rotor 4 provided near the center of the main wing 1
, Two rotational forces, the rotational force of the rotary rotor 4 and the rolling force of the fuselage, act on two orthogonal axes, that is, the center line of the rotary rotor and the fuselage center line.
A gyroscope precession acts on the rotating rotor 4 about another orthogonal axis and another axis.

That is, a precession about the z axis of the orthogonal axes indicated by the x, y, and z axes in FIG. 1 occurs. Therefore, the gyro is rotated so that the entire body of the airplane toy A counteracts the direction of rotation by the rolling motion, and at the same time, the nose rotates in the right direction toward the traveling direction until the rolling force acting on the wings becomes uniform. Scope precession works. If the size, mass, and rotational speed of the rotating rotor 4 are given so that the magnitude of the gyroscope precession becomes sufficiently large to be able to oppose the size of the body that is going to turn by the rolling motion, The aircraft is prevented from shifting to the left, and the straightness of the aircraft is eventually secured. Therefore, flight stability can be obtained without the vertical tail.

Although the above operation has been described for the case where the aircraft rolls to the left, it is exactly the same when rolling to the right. The rolling motion to the left and right is canceled by the gyroscope precession, and the nose is always moved. By matching the airflow direction, flight stability can be ensured.

The above operation is basically the same in the case of (a) the swept wing and (b) the dihedral angle shown in FIG. 5, but the rotating direction of the rotary rotor 4 is changed by the launch pad. Or the main wing has a dihedral shape and the rotating direction of the rotating rotor 4 is in the opposite direction, or the center position of the rotating rotor 4 is effective from the center of gravity of the fuselage. When the vehicle is far away, the straightness of the aircraft cannot be ensured as described above.

When the airplane toy of this embodiment is used as a playground equipment, it is advantageous to attach a hook-and-loop fastener to the rotating rotor 4 as described above in order to increase the competitiveness of the game. For example, when a cloth such as a curtain in a room is made into a dart shape and a plane toy is made to fly toward the cloth, the planes fly and compete for points by utilizing the fact that the rotating rotor 4 sticks to the curtain by the hook-and-loop fastener. And so on.

FIG. 7 shows an application example in which the shape is different from that of the first embodiment. Although the appearance is in the form of a car such as a race car, the main wing 1, the fuselage 2, and the horizontal tail 3
It is an airplane toy having.

FIG. 8 is an external perspective view of an airplane toy according to another embodiment. A doll-shaped body 2 and a foot-shaped tail 3 are provided below the main wing 1, and a rotating rotor 4 is provided inside the body 2 near the front end.
Having.

7 and 8, the basic operation is the same as that of the first embodiment, and the flight is stabilized by the action of the gyroscope precession by the rotating rotor 4 without the vertical tail. I am trying to gain sex.

9 is an airplane toy having only the main wing 1 and the fuselage 2, FIG. 10 is an airplane toy in which the main wing 1 and the fuselage 2 are integrated (combined type), and FIG. 11 is an airplane toy in which the main wing 1 and the fuselage 2 are integrated. It is an example of a UFO (unidentified flying object) type airplane toy.

Although neither of them is provided with not only the vertical tail but also the horizontal tail, flight performance is sufficient because the rotating rotor 4 basically ensures flight stability. An advantage of these three examples is that various appearance designs can be employed.

FIG. 12 is an external perspective view showing another embodiment of the launch pad B 'and a sectional view taken along the line BB. The airplane toy fired by the launch pad B 'in this embodiment is shown in FIG.
The horizontal tail 3 of the above example is integrated with the fuselage 2
Although an example of formation is shown, it goes without saying that the airplane toy is not limited to this and may be any of the airplane toys shown in FIGS. In any case, as for the launch table B ', only the rotary rotor 4 has a shape in which a plurality of notches 4x are provided in a part thereof as shown in the drawing.

As shown, the connecting member 1 of the firing substrate 11
The upper end of a compression head 13 'of the compressed air generator is detachably attached to 1a. A compressed air nozzle 15 'is provided above the compression head 13', and a control valve (not shown) provided in the compression head 13 'is operated by a firing lever 14' to compress the compressed air from the nozzle 15 'at the tip. Air is blown out. 15a 'is a spray pipe.

The compression head 13 ′ moves up and down to generate compressed air in an internal cylinder, stores the compressed air in an air tank 16, and controls the inside of the compression head 13 ′ through a connecting pipe 17. I try to lead to the valve.

According to the launching table B 'of this embodiment, the compressed air is generated by pulling the firing lever 14'.
The rotation of the rotary rotor 4 and the thrust of the machine body are given by spraying the required amount from the rotor 5 to the rotary rotor 4 as in the case of the example of FIG.

FIG. 13 is a schematic perspective view showing an example in which a motor is used as a means for applying a rotating force to the rotating rotor 4.
An airplane toy having a body shape in which a main wing 1, a fuselage 2, and a tail wing 3 are integrally formed is shown as an example. The flight performance is exactly the same as that of the example of FIG. 1, but the method of applying the thrust to the rotating rotor 4 is completely different.

A motor 7 is attached to the rotating rotor 4 to apply a rotating force. The power supply to the motor 7 connects the battery 10 to the terminals 9a and 9b when the power supply to the capacitor 8 is stopped.
The connection is made via When the power supply to the capacitor 8 is completed, the battery 10 is removed, and when the motor 7 is rotated, the switch 8x is turned on to drive.

It is preferable that the center point of the rotating rotor 4 is provided on the center line (length direction) of the body. For this reason, when the weight of the motor 7 causes an unbalance in the distribution of the overall weight, a balanced additional weight portion is provided, or the motor is mounted such that the center point is located on the fuselage center line, and the motor output is reduced by a gear. It is preferable that the power can be transmitted to the rotating rotor 4 via the motor.

In this case, the thrust for flying is given manually. What is necessary is just to throw the illustrated airplane toy in hand in a state of rotating the rotating rotor 4 so as to fly at a predetermined height. At this time, it is a condition that the rotation direction of the rotating rotor 4 is naturally set to the same direction as the example of FIG.

The example of FIG. 14 is an example of an airplane toy in which the battery 10 is incorporated in the fuselage 2 instead of the capacitor of the example of FIG. It is naturally preferable that the battery 10 is also provided on the fuselage center line.

In the example of FIG. 15, the battery 10 of the example of FIG. 13 is used as a solar cell panel 10 'to obtain power from sunlight.

FIG. 16 et seq. Show an example of an airplane toy that makes a boomerang flight. FIG. 16 is an external perspective view of the airplane toy of this example. This airplane toy is an example in which the main wing 1 and the horizontal tail (elevator) 3 are integrated and the fuselage is omitted, or is to be regarded as included in the integrated airframe. Basically, the same members as those in the example of FIG. 1 are denoted by the same reference numerals, and the following description will focus on features unique to this embodiment.

The main wing 1 of this embodiment is provided with ailerons 1E (auxiliary flaps) on the left and right, and the horizontal tails (elevators) 3, 3 can be bent upward with respect to the main wing 1 at straight lines L, L. It is provided to be able to. In this example, the main wing 1 is made of plastic so that straight lines L, L can be creased and bent upward.

The main wings 1, 1 are provided at the center thereof with a hollow tube 7 'using a straw along the flight direction. The hollow tube 7 ′ has a front end extending to a position short of the rotary rotor 4, and a rear end set to slightly project from the rear ends of the horizontal tails 3, 3. This rear end may be provided by being bent upward from the surface of the main wing 1 or the horizontal tail unit 3 in addition to the above.
In that case, it is not necessary to have a length protruding from the tail 3.

As shown in FIG. 17, the hollow tube 7 'is provided at the center of the main wings 1 and 1 so that the center line thereof substantially passes through the rotating shaft 4a of the rotating rotor 4, and as shown in FIG. The upper half of the outlet 7a 'is closed with a small piece 7p' so that the outlet 7a 'at the front end is located slightly below the center line. As a result, the air blown from the outlet 7a 'hits the outer periphery of the rotary rotor 4 at a position slightly shifted from the center line, thereby rotating the rotary rotor 4 in the direction of the arrow (clockwise) in the figure.

In the above example, the front end of the hollow tube 7 'is provided in a horizontal straight line, and the outlet 7a' is vertically asymmetric so that the rotating rotor 4 is rotated by the blown air. Besides, for example, the predetermined length of the front end of the hollow tube 7 ′ is bent slightly obliquely downward, and the outlet 7 a ′ blows the blow air slightly obliquely to the rotor 4 to rotate the rotor 4. (In this case, the small piece 7p 'is unnecessary). 4x is a hook-and-loop fastener.

The rotating rotor 4 supports the rotating shaft 4a with a bearing 5, which is in the form of an L-shaped lever as shown in FIG. The rotor 4 is supported so that the rotor 4 is positioned in a notch 6 near the center front edge of the main wings 1 and 1 so as to sandwich the vicinity of the front end of the rotor. 5x is a notch space formed inside the arm of the bearing 5.

The airplane toy of this embodiment having the above configuration is lighter and easier to handle than those of the other examples described above, and has high practicability in consideration of safety when used as a toy. It is. The method of use will be described with reference to FIGS.

As will be described later, the purpose of the airplane of this example is basically to draw a certain turning radius so as to fly as a boomerang and to play as a playground equipment. The turning flight at that time is rotated in the direction of the arrow shown in FIG.

In order to give this rotation, as shown in FIG. 19, the rear end of the hollow tube 7 'is held in the mouth, and breath is blown, and air is blown from the front end of the hollow tube 7' to the rotating rotor 4. In this case, as described above, the front end outlet 7a 'of the hollow tube 7' is slightly displaced from the center of the rotating rotor 4, so that it always rotates in a certain direction as shown by the arrow.

With the rotating rotor 4 rotated as described above, as shown in FIG. 20, one side of the main wing 1 is sandwiched between fingers to hold the body substantially vertically, and the arm is thrown to throw out.
As shown in FIG. 21, the airplane toy makes a boomerang flight while turning and returns to the initial position.

FIGS. 20 and 21 show a case where the vehicle turns right. For this right turn, as shown in FIG. 20, the aileron 1E of the left main wing 1 is set upward at a large angle with the left main wing 1 turned upward, and the aileron 1E of the right main wing 1 is set downward at a small angle (FIG. 16). (Upward and downward with reference to the upper and lower surfaces of).

When the left and right ailerons 1E and 1E are set to fly as described above, the wings 1 and 1 are gradually rotated by the gyro moment of the rotating rotor 4 during the flight even if the body is sent out vertically. As 1 approaches the horizontal state, lift is generated and the flight continues, and in the above example, the vehicle returns to the initial position while making a stable right turn.

The above description is for a right turn, but in the case of a left turn, as shown in FIG.
If the upper and lower aeron 1E is turned upside down, that is, the upper and lower surfaces of the fuselage are turned upside down and the upper aileron 1E is set at a small angle toward the upper surface of the fuselage and sent out, the fuselage turns left.

When turning left, the angle of the aileron 1E shown in FIG. 20 is set upside down, that is, the upper aileron 1E is set at a large angle toward the lower surface and the lower aileron 1E is set at a small angle toward the upper surface. The aircraft does not make a left turn even if it is sent out vertically.

Also, when the ailerons 1E, 1E are set in the reverse of the above-described relationship for the left turn shown in FIG. 22, the right turn is not performed. This is because the rotation direction and the turning direction of the rotating rotor 4 are different in each case.

Therefore, for example, the hollow tube 7 ′ is provided rotatably around its central axis, and the hollow tube 7 ′ is arranged so that the relationship of the displacement of the front end outlet with respect to the rotary rotor 4 is upside down. When rotated 180 °, the rotating rotor 4
0, rotate in the direction opposite to the direction of the arrow in FIG. Therefore, FIG.
If the ailerons 1E and 1E are set in the opposite relationship at 22, the right turn and the left turn are performed normally, so the right turn and the left turn are performed by rotating the hollow tube 7 '. It may be set.

As described above, when making a boomerang flight by turning right or left, the elevator angle of the horizontal tail 3 is fixed to an arbitrary set angle. When the elevator angle is set to be large or small, the turning radius becomes large or small as shown in FIG.

In the embodiments shown in FIG. 16 and subsequent figures, the main wing 1,
Although the boomerang flight is enabled by providing the auxiliary flaps (ailerons) 1E and 1E in the first embodiment, the auxiliary flaps may be provided in each of the embodiments before FIG.

[0066]

As described above in detail, the airplane toy according to the present invention has a rotating rotor provided near the center of gravity of the aircraft, omits the vertical tail, and imparts rotation to the rotating rotor in a predetermined direction, so that the airframe is subject to wind or the like. since attempts to rotate by rolling and yawing motion effects for the rotation thereof and configured to canceling Suyo by gyroscopic precession, thereby ensuring the stability of the flight, the design obtained by modifying the shape of the body in a variety of forms Therefore, there is obtained an advantage that the use as a playground equipment on the premise of competitiveness of competing for a flight distance and a flight time is increased.

In the airplane toy of the second invention, the main wing and the fuselage or the fuselage are integrated. However, even in such a shape, the straightness and stability of flight are maintained by the action of precession by the rotating rotor as in the first invention. There is an advantage that the same can be obtained and the design can be diversified.

In the third invention, a hollow tube is provided at the center of the body as a means for imparting rotation to the rotating rotor, and the rotating rotor is rotated by the air blown out. It greatly contributes to the practical use of toys.

In the fourth invention, since the auxiliary flap is provided on the main body wing, the toy of the airplane toy can stably perform boomerang flight by setting the setting angle of the auxiliary flap in the left and right main wings in different directions. Thus, a more practical airplane toy can be obtained in combination with the weight reduction of the rotation applying means.
