2. Description of the Related Art It is humanity's dream that humans can fly freely in the sky like birds, and many ancestors are trying to fly, but it has not been realized yet. Therefore, hang-riders and paragliders are only used to fly in the air.

However, the hang-rider and the paraglider select a mountain where the airflow is gentle and high, jump off from the launcher stand at the summit, grab the thermal on the way, and fly leisurely. You cannot climb or fly forward.

[0004]

As described above, the hang-rider and the paraglider only fly by gliding or descending by utilizing the airflow, and actively generate levitation and propulsion to fly freely. While controlling the state,
It is impossible to fly toward the target point, and it is impossible to “fly freely in the sky like a bird”, which is the dream of mankind.

A technical problem of the present invention is to pay attention to such a problem and to easily generate a large levitation force or propulsion force even by human power so that the man can fly freely in the sky.

At the front end of each rib 28a ...
a is inserted, one end 29a1 is fixed to the front end of the outermost blade frame 26a via a tension coil spring,
The other end 29a2 is guided to the support shaft connecting frame 301 via the support shaft 19a. A string-like body 31a is inserted through the rear ends of the ribs 28a, one end 31a1 is attached to the rear end of the outermost blade frame 26a, and the other end 3 is attached.
1a2 is attached to the rear end of the support shaft 19a.

Now, the other end 29a of the front string 29a
2a and the support shaft 19a are inserted through the hook 32a
Is pulled, the outermost wing frame 26a is pulled toward the support shaft 19a, and the two parallel frames 24a, 25a and the outermost wing frame 26a approach each other until they are substantially parallel to the support shaft 19a. Folds compactly as shown in FIG.

In this state, as shown in FIG. 5, when the hook 32a is hooked on the pin of the intermediate support shaft connecting frame 302, the blade 1a is folded. The sheet-like bodies 3a and 3b are made of, for example, Dacron 60Z (trade name) and have a high degree of flexibility, so that they can be folded at the positions of the ribs 27a and ribs 28a.
Note that 1ax is the state of being folded in this way.

On the blade 1b side, in the same manner, the support shaft 19b is formed.
On the other hand, it is attached so that it can be folded. A torsion coil spring 33b is attached to the mounting plate 21b, one end of which is locked to the support shaft 19b and the other end of which is locked to the wing frame 23b, so that the wing frame 23b is extended by a spring force. Therefore, in the illustrated example, when the hook 32a is removed from the pin of the support shaft coupling frame 302, the wing 1b is extended by the spring force of the torsion coil spring 33b and spreads to a flightable state.

The blade 1a (1b) is provided with an opening 14 as illustrated in FIG. 2 (b), and the blade 4a (4b) larger than the opening 14 is formed.
Are integrally connected to the sheet-like bodies 3a (3b) of the blade 1a (1b). Therefore, when the blade 1a (1b) descends, the blade 4a (4b) closes, and a levitation force is generated in the blade 1a (1b),
When (1b) rises, these blades 4a, 4b open and wing 1a
(1b) can be easily raised.

As illustrated in FIG. 6, rod-shaped connecting means 35a and 35b are attached to the shaft supporting portions 34a and 34b of the blade frames 22a and 25a, and the other end is connected to the shaft supporting portions 34a and 34b. It is guided to the operation parts 36a and 36b of the passenger 7. By attaching a grip 36g or the like to the ends of the connecting means 35a, 35b shown in the figure and reciprocating the grip in the direction of the arrow a ₁ , the wings 1a, 1b can be easily flapping, but FIG. In the embodiment of FIG. 7, a device as in claim 5 is devised so that the flapping operation can be performed more easily.

6 and 7, the support shafts 19a and 19b are provided.
The main frame is composed of the hanging frames 8a and 8b in which the both support shafts 19a and 19b are rotatably inserted, and the frame 8c that connects the hanging frames 8a and 8b. Then, a leg 38 having wheels 37 for sliding is attached to the connecting frame 8c, and the lower arm 3 of the two arms 39 and 40 connected in a dogleg shape.
The lower end 391 of the shaft 9 is rotatably supported on the leg 38, and the upper end of the upper arm 40 is connected to a slider 41 which is guided by the leg 38 and moves up and down. Leg 38
An elastic pressure means (compression coil spring) 42 for moving the slider 41 to the wheel 37 side is attached to the.

Further, the slider 41 and the connecting frame 8
The shaft support portion 43 is provided at a position between the shaft support portion c and the tip end of the pair of telescopic rods 44a and 44b supported by the shaft support portion 43 and the blade frame supporting the blades 1a and 1b. Are connected by connecting rods 35a and 35b, and driving portions 36a and 36b by a human arm force are provided at the connecting portions.

The pair of telescopic rods 44a,
The non-stretchable side (base end side) of 44b and the slider 41 are connected by arms 45a and 45b. On the other hand, a wire 46 that pulls the lower arm 39 connected in a dogleg shape in a direction in which the dogleg arms 39 and 40 extend penetrates the guide tube 47 and is operated by the right hand. It is guided to the portion 36b.

Therefore, when the lever 48 arranged on the operation portion 36b is grasped by the right hand, the wire-like body 46 is pulled, the dog-legged arms 39 and 40 are extended against the compression coil spring 42, and the arm 45a. , 45b,
The telescopic rods 44a and 44b are pivotally moved up about the shaft support portion 43, and the wings 1a and
Raise 1b.

After all, in this embodiment, the wings 1a and 1b are lifted by grasping the lever 48 and extending the dog-legged arms 39 and 40, and the wings 1a and 1b are lowered by the arm force. This is performed by pulling the rods 35a and 35b. FIG. 9 shows an embodiment for reducing the gripping force of the lever 48. A torsion spring 49 is wound around the shaft of the shaft support 43, one end 49a of the torsion spring 49 is locked to the telescopic rod 44a on the wing 1a side, and the other end 49b is locked. It has a structure in which it is locked to a telescopic rod 44b on the wing 1b side.

[0072] In this embodiment, both ends 49a of the torsion spring 49, the spring force of 49b, as indicated by arrow a _2, a _3,
Since the force for raising both the telescopic rods 44a, 44b acts, the gripping force of the lever 48 is reduced, and the wings 1a, 1b can be raised with a light force. 6 and 9, the blades 1a and 1b are horizontal, and the blades 1a and 1b are horizontal.
Is a state where the blades 1a and 1b are descending, and the flapping operation is repeated between and.

At the time of takeoff, while alternately repeating the operation of lowering the wings 1a, 1b by the arm force and the operation of raising the wings 1a, 1b by the grip force, the person manually pushes the flapping flight device as shown in FIG. Then support shafts 19a, 19
The abdomen is placed on the belt 50 hung on b, and both legs are placed on the belt 51 at the rear end so that the human body 7 is in a horizontal state.

The flapping flight device moves forward due to the inertia when it glides, but since the wings 1a and 1b are curved so as to be convex upward, the air flow on the upper side becomes faster than that on the lower side, and the air pressure on the upper side changes. Since it is lower than the lower side, levitation force is generated. Therefore, it is possible to efficiently levitate in combination with the levitating force caused by the flapping motion.

Both wings 1a and 1b may be rotatably supported by separate support shafts 19a and 19b as in the embodiment of FIG. 6, but as shown in FIG. 1 (b). It may be supported on a common shaft.

In contrast to the fifth embodiment, in the sixth embodiment, as shown in FIG. 1, both blades 1a and 1b exert a force in a direction of rotating up or down about the shaft supporting portion. It has elastic means 9a, 9b for generating.

For example, in FIG. 1, the main frame 8
The poles 52 and 53 are erected to connect the upper ends 54, and between the upper ends 54 and the wing frames of the respective wings 1a and 1b, an elastic body 9 such as a rubber string or a tension coil spring is provided.
a, when connected by 9b, always wings 1a, resilient in a direction to increase the 1b (arrow a _2, a ₃ directions) occurs.

Therefore, the occupant guides the tip ends of the wire-shaped bodies 11a and 11b connected to the wing frame to the operation portion of the person 7 who is on the main frame 8 and pulls the wire-shaped bodies 11a and 11b. Alternatively, the levitation force can be generated by vertically moving the wings 1a and 1b only by intermittently repeating the operation of opening or releasing.

Contrary to the illustration, the main frame 8 and the wings 1
The wing frames of a and 1b are connected by a tension elastic body such as a rubber string or a tension coil spring, and the wings 1a and 1b are lowered by a spring force to generate a levitation force.
It is also possible to guide the wire-like body connected to the wing frame of b to the position of the occupant through the connecting portion 54, and the occupant pulls the wire-like body to raise the wings 1a and 1b.

In this way, the wings 1a, 1b can be raised (or lowered) by the spring force, and the wings 1a, 1b can be lowered (or raised) by the human force against the spring force.

On the other hand, in claim 7, both the raising and lowering of the wings 1a, 1b are performed manually. FIG. 10 shows an embodiment thereof, in which, at the position of the legs of the occupant, pedals 57a fixed to the bearings 55 mounted on the main frame are rotatably supported by cranks 56a and 56b having a mechanism similar to that of a bicycle. , 57b have pedals 58a, 58b attached thereto.

A guide 5 such as a pulley is attached to the top ends 54 of the poles 52 and 53 standing on the main frame 8 in FIG.
Wires 60a and 60b, which support 9a and 59b and are connected to the wing frames of both wings 1a and 1b from above, are connected to the pedal shaft 5 of one side through the guides 59a and 59b.
7a and connect.

Further, guides 61a and 61b such as pulleys are attached to the main frame 8 and the like below the wings 1a and 1b.
The guides 61a, 62a, 62b, which are connected to the wing frames of both wings 1a, 1b from below,
It is guided and connected to the other pedal shaft 57b via 61b.

According to this structure, one pedal shaft 57a
However, when moving toward the rear end of the flapping flight device, the wires 60a and 60b are pulled to raise the wings 1a and 1b, and at the same time, the other pedal shaft 57b moves toward the front end of the flapping flight device. 62a and 62b are loosened.

On the contrary, when one pedal shaft 57a moves toward the front end of the flapping flight device, the wire 60
a and 60b are loosened, the other pedal shaft 57b moves toward the rear end of the flapping flight device, and the lower wires 62a and 62b of the wings 1a and 1b are pulled, and the wings 1a and 1b are pulled down.

It is also possible to provide a crank mechanism at the position of the occupant's arm and pedal the pedal with both hands. Since the wires 60a, 60b, 62a, 62b in the illustrated example are stretched obliquely, the efficiency of the force is low and a large force is required. Therefore, a guide means such as a pulley is attached to an auxiliary frame or the like at right angles to the main frame, just above and below the wire attachment positions 34a and 34b, and the wire 60 is attached.
If the a, 60b, 62a, 62b are pulled in the direction perpendicular to the plane of the blades 1a, 1b, they can be easily flapping with a small force, and the wires 60a, 60b, 62a, 62
As b, a material having low tensile strength can be used.

An eighth aspect of the present invention is an apparatus adapted to obtain a larger propulsive force.
When a and 1b rise, they open to allow air to pass,
The unidirectional opening / closing means 2a, 2b, which are closed to prevent air from passing when the a, 1b descend, are attached to both blades 1a, 1b.
As shown in FIGS. 1 (a) and 1 (c), when the blades 1a and 1b rise to the front-lowering oblique blades 12a and 12b provided at the tips of both blades 1a and 1b, A unidirectional opening / closing means 13a that opens to allow air to pass therethrough and closes when the wings 1a and 1b descend to prevent air from passing therethrough.
13b is provided.

With this structure, as shown in FIG. 1D, when the blades 1a and 1b descend, the oblique blades 12a and 12b are moved.
The force P acting on the lower surface of the flapping flight device can be divided into a force P1 in the direction to levitate the flapping flight device and a force P2 in the direction to advance the flapping flight device. As you can see, wing 1
When flapping operation of a and 1b is performed, the oblique blades 12a and 12b are
Since the forward force is generated at, it is possible to efficiently generate the propulsive force to move forward.

FIG. 11 is a plan view and a side view showing an embodiment of claim 9 for generating a propulsive force in a flapping flight apparatus having wings 1a and 1b having unidirectional opening / closing means 2a and 2b. It has a rotary vane 70, and is structured to be rotationally driven by human power or mechanical power. The rotary vanes 70 may be propeller-shaped ones in a propeller machine, and the number may be either single or plural. In the illustrated example, a bevel gear is attached to the shaft of a foot-type crank in a bicycle similar to the case of FIG.
71 is provided, and the bevel gear 72 having a small diameter is used to accelerate the propeller 70 so that the propeller 70 is rotated.

When the shaft of the propeller 70 is always kept horizontal, only the force in the forward direction can be obtained, but if it is tilted upward, the levitation force can be generated in addition to the forward force. Further, if the vehicle is tilted in the left-right direction, steering becomes possible. The propeller
The rotational drive of 70 may be a combination of a screw rod and a nut that rotates the nut only in one direction, or a combination of a rack and a pinion that allows the pinion to rotate only in one direction. The illustrated crankshaft may be rotationally driven by a motor M, an engine or the like.

A tenth aspect of the present invention is the blades 1a and 1b of the first to ninth aspects.
The unidirectional opening / closing means 13a, 13b in 1 can be opened by the operation of the passenger, and the opening amount can be controlled. For example, as shown in FIG. 2B, the blade 4a (4b) is normally closed by utilizing the elastic force of the tension coil spring 17 or the like or by the levitation force. Further, when the wings 1a and 1b are operated by flapping, they only float.

Therefore, when riding in an ascending air current, it is difficult to descend or land, but connect the wire 68 to the blades 4a (4b) of FIG. 1 (a) as shown in FIG. 2 (b). Then, using the pulley 69 as a guide, guide it to the passengers' hands. And when you want to descend, the wire
68 and pull down the blades 4a (4b) to open the opening 14
When opened, air will leak upwards, reducing the levitation force and gradually descending. The descending speed can be easily controlled by manipulating the opening amount of the opening 14.

FIG. 12 shows a twelfth embodiment of the present invention, in which the front-lowering oblique blades 12a and 12b are pivotally supported at the front ends of the blades 1a and 1b so as to be rotatable back and forth. In this embodiment, the torsion spring 63 allows the oblique blade 12a,
An elastic force acts in the direction in which 12b pivotally moves forward. Then, it is positioned by hitting a stopper 64 that sets the inclination angle of the oblique blades 12a and 12b.

Wires are attached to the lower ends of the oblique blades 12a and 12b.
65 is tied together and is guided to the tip of a lever 66 for front-back drive. The front-rear drive unit is designed so that an occupant moves the lever 66 rearward manually, by leg force, or by power, and the lever 66 is normally pulled forward by the elastic force of the torsion spring 63.

[0095] flapping when advancing the flight device, when a force for moving such a lever 66 backward by human power, Hasutsubasa 12a, 12b is against the torsion spring 63, rotating in the arrow a ₄ direction wire 65 Move dynamically. At this time, since the unidirectional opening / closing means 13a and 13b are closed by the resistance of the air, a propulsive force in the direction of moving the flapping flight device forward is generated, and the flapping flight device can be efficiently moved forward.

When the force for moving the lever 66 rearward is released, the elasticity of the torsion spring 63 causes the oblique blades 12a, 12
b returns to the original position shown by the solid line. At the time of the returning operation, the unidirectional opening / closing means 13a, 13b open due to the resistance of the air, so that the oblique blades 12a, 12b can be easily returned by the elasticity of the torsion pulling 63. Therefore, the forward movement can be easily performed only by repeating the forward / backward movement of the lever 66, and the forward movement speed can be easily controlled by the speed and frequency of the lever operation.

In the case of riding in an updraft, the blade 1a,
If the flapping operation of 1b is stopped and only the oblique blades 12a and 12b are rotated back and forth, only forward movement is possible, and the operability of the flapping flight device is improved. Left and right oblique blades 12a and 1
If the frequency and speed of the forward and backward movements with respect to 2b are changed and they are operated separately, the steering in the left and right direction becomes easy.

Without using the torsion pulling 63, FIG.
In the above application, both the forward and backward directions of the oblique blades 12a and 12b can be driven by human power alone or by power. The frame 67 attached to the outer periphery of the oblique blades 12a and 12b is used for reinforcing the oblique blades 12a and 12b and the wire 6.
5 is for mounting. In the illustrated example, the oblique blade 12a,
Although 12b is attached to the front ends of the wings 1a and 1b, it may be attached to other portions.

A thirteenth aspect of the present invention is a vertical moving oblique blade 1 according to the eighth aspect.
In addition to 2a and 12b, or in place of the front-rear rotating oblique blades 12a and 12b of claim 12, propulsion blades that reciprocate in the front-rear direction are attached to a rigid body such as a main frame. FIG. 13 is a plan view and a side view showing this embodiment. Propulsion wings 74a and 74b are axially supported by a horizontal shaft 73 attached between main shaft support shafts 19a and 19b. Has unidirectional opening / closing means 13a, 13b having substantially the same configuration as that shown in FIGS. The propulsion wings 74a, 74b are supported by elastic means 75a, 75b such as rubber or a tension coil spring for supporting shafts 19a,
It is pulled to the 19b side.

Foot-operated levers 76a and 76b are connected to the propulsion wings 74a and 74b, and elastic means 75a and 75b are connected.
When the levers 76a and 76b are alternately stepped against the pulling force of
Propulsion blades 74a, 74b is rotated forward or arrow a ₅ direction from the dashed line position, and closing means 13a, 13b is opened, it can be rotated forward with a light force. Next, when the stepping force is released, the propulsion blades 74a, 74b are rotated toward the support shafts 19a, 19b by the force of the elastic means 75a, 75b and fall down as shown by the broken lines, and in this process, the opening / closing means 13a, 13b are opened. Since it closes, air is pushed out backwards and propulsive force is generated.

If a sheet-like member is attached to the support shafts 19a and 19b just below the propeller blades 74a and 74b, the propeller blades 74a and 74b will be
The air pushed away by the 74b causes the sheet-like body and the propulsion wing 74
Since a and 74b are surely pushed to the rear, a large propulsive force can be obtained. The pair of propulsion wings 74a, 74b
Can also be combined into a single configuration.

FIGS. 14 (a) and 14 (b) show an embodiment of claim 14 in which unidirectional opening / closing is performed by using a propulsion wing having unidirectional opening / closing means instead of the sheet-like body in FIG. Means 13a,
This is an example in which a pair of propulsion blades 74a and 74b having 13b are provided in a V shape. The pair of propulsion blades 74a, 74b are arranged rearward in a V-shape and can be opened and closed about the front shaft 73.
(a) is a perspective view, and a pair of propulsion blades 74a, 74b are supported by a common shaft 73, while (b) is a horizontal sectional view, in which a pair of propulsion blades 74a, 74b are separated. It is supported by shafts 73a and 73b.

[0103] Now, a pair of propulsion blades 74a, the 74b is closed to drive in the direction, unidirectional closing unit 13a, an opening 14 is closed at 13b, it is displaced to ensure that the arrow a _6, a ₇ direction air Therefore, a large propulsive force can be reliably obtained. (b) When the space between the two support shafts 73a and 73b in the figure is closed by the sheet-like body 77 to prevent air from escaping forward, the propulsive force can be further increased.

(A) As shown by the chain line in the figure, if plate-like bodies 78 and 79 are arranged in the upper and lower openings of the V-shaped propulsion blades 74a and 74b to prevent air from escaping from above and below, , The driving force becomes even stronger.

In the figures (a) and (b), the pair of propulsion blades 74a and 74b are V-shaped.
Whereas an angle in shape, (c) drawing a pair of propulsion blades 74a, 74b are positioned on a straight line, as indicated by an arrow a _8, propulsion direction F with respect to the vertical line L1 It reciprocates around. Alternatively, the structure may be such that it reciprocally rotates within a range of 90 degrees as shown by an arrow a ₉ .

In (d), a pair of propulsion blades 74a, 74b angled in a V-shape or a V-shape are fixed so that they cannot be opened and closed, and are driven forward and backward as a whole in a fixed state. In this case, when the integral propulsion blades 74a, 74b move rearward, the air can be effectively pushed out backward so as not to escape, so that a large thrust is generated. When the integral propulsion blades 74a, 74b move forward, air easily escapes from the slope and the unidirectional opening / closing means 13a, 13b open.
Air easily escapes from the opening 14, and the pair of propulsion blades 74a and 74b can be moved forward with a light force.

The gap with 80 is small, and the unidirectional opening / closing means 13 is opened, so that the air taken in from the front direction can be surely pushed out to the rear to generate a propulsive force.

15 (b) (c) (d), a poppet valve-shaped propulsion blade 81 is reciprocated in a straight line in a tubular body 80. That is, (b) the reciprocating plate 83 having the opening 82 as shown in FIG.
It is supported so that it can be opened and closed via 84 etc. Therefore, when the wires 60 and 62 illustrated in FIG. 10 and the like are connected to the reciprocating plate 83 and moved backward as shown in FIG.
When 82 is closed, the air in the tubular body 80 is pushed out rearward and a large thrust is generated.

On the contrary, when the reciprocating plate 83 is moved forward as shown in (d), the opening 82 is opened, and the air flowing into the tubular body 80 passes through the opening 82 and moves backward. Since it flows, the reciprocating plate 83 is easily returned with a light force to prepare for the next generation of thrust. The tubular body 80 is a rectangular or circular tube depending on the outer shapes of the propulsion wings 74, 81 incorporated therein. It should be noted that by rotatably supporting the tubular body 80 and orienting it vertically or horizontally, steering in the up-down direction and the left-right direction can be performed reliably and easily.

In each of the above embodiments, the flapping operation of the wings 1a and 1b and the driving of the propulsion wings can be performed by at least one of human arm force, leg force, or mechanical force (power). For example, it is possible to perform a flapping motion with the occupant's strength and leg strength, and to use a light power supplementarily. Alternatively, it is possible to improve the operability and controllability by flapping the wings 1a and 1b with a light power and using human power as an auxiliary.

In addition, when the flying speed is slow only by the flapping operation by the wings 1a, 1b, a balloon-like container that can be filled with an auxiliary gas such as He gas, which is lighter than air, is installed in the main frame or both wings 1a, 1b.
