Description

[0001]
[Industrial application fields]
The present invention relates to a flapping flying device that generates a levitation force by moving a pair of wings up and down, and more particularly to a flying device that flutters wings by human power.
[0002]
[Prior art]
Inventor of the present invention, in Japanese Patent Application No. 5-177078, the wing that flutters up and down is provided with unidirectional opening and closing means that closes when the wing is lowered and opens when the wing is raised, thereby efficiently generating levitation force. In addition, a device that flutters with human power or auxiliary power was proposed.
[0003]
[Problems to be solved by the invention]
However, in the previous invention, in order to move the wing up and down, a grip portion is provided on the bar connected to the wing, and the grip portion is moved up and down with both hands.
[0004]
According to this structure, since the grip part needs to be moved up and down and the bird's wings flutter, a force for moving the wing up and down is difficult to enter, and it is easy to get tired. For this reason, levitation is difficult, and long-time flapping operations are difficult.
[0005]
The technical problem of the present invention pays attention to such a problem, and by making it possible to easily move the wing up and down with a light force, it is possible to levitate efficiently and to perform a long-time flapping operation. There is.
[0006]
[Means for Solving the Problems]
The technical problem of the present invention is solved by the following means. According to the first aspect of the present invention, the left and right wings are supported so as to be able to flutter up and down, and when both wings are lifted, they are opened to allow air to pass, and when both wings are lowered, the wings are closed to prevent air from passing. In a flapping flight apparatus in which directional opening and closing means are provided on both wings, a main body side bar pivotally supported by a lower frame provided below the support part of both wings, and a wing side bar pivotally supported by left and right wing frames and connecting shaft supported bets, a possible structure folded middle inside, the connecting shaft bearing or the body side bar upper or blade-side bar the lower end of the main body side bar and the blade-side bars and provided with a driving portion such as the grip means When both wings are lifted due to air resistance acting on both wings, the wing side bar and the main body side bar of the middle-fold structure extend in a straight line, and when the force pulling the driving part inward acts, the wing side bar and the main body side The bar is folded inward and both There it has a structure in which downward is pulled downwards, a human powered flapping flying device, characterized in.
[0007]
In this way, the lower frame and both wings are connected by a bar having a half-folded structure, and gripping means provided at the middle-folded portion (the connecting support portion between the main body side bar and the wing side bar) or the main body side bar upper end or the wing side bar lower end The gripping means does not move up and down, but reciprocates in a substantially horizontal direction. As a result, it is easy to apply force and it is difficult to get tired, so that a long-time flapping operation is possible.
[0008]
Claim 2 is to have human powered flapping flying device which has a resilient means for generating a force for straight extended by elasticity of the main body side bar and the blade-side bar in the claim 1.
[0009]
Since such a bar having a folded structure composed of a main body side bar and a blade side bar has elastic means in a direction to straighten, a force in a direction to raise both blades acts by this elastic means. .
[0010]
Therefore, it is sufficient for the human power to generate a force in the direction of lowering both wings, that is, the direction of pulling the grip means against the elastic force of the elastic means.
[0011]
The elastic force by the elastic means and the upward air resistance acting on the wings cause a force in the direction in which the bent bar is straightened, so that a force for raising the wings is not so necessary.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of how the flapping flight apparatus according to the present invention is actually realized will be described. FIG. 1 is a front view of a flapping flight device according to the present invention, in which a sail is not shown. FIG. 2 is a front view for explaining the flapping operation in the flapping flight apparatus.
[0013]
Since the flapping flight apparatus of the present invention is an improvement over the flapping flight apparatus disclosed in the previously filed Japanese Patent Application No. 5-177078, the entire flapping flight apparatus of the previous invention will be described first in FIG.
[0014]
In FIG. 4, (a) is a plan view showing the whole flapping flight apparatus according to the present invention, (b) is a cross-sectional view taken along line bb in (a), and (c) is c in (a). -C sectional drawing, (d) figure is a figure explaining a drive action.
[0015]
Reference numerals 1a and 1b denote left and right wings, which have a structure in which sails made of sheet-like bodies 3a and 3b are stretched on wing frames and support wires (not shown). The wings 1a and 1b are lifted up and down by human power and power to generate levitation force.
[0016]
However, when the wings 1a and 1b are raised, the unidirectional opening and closing means 2a and 2b are opened to allow air to pass therethrough and closed when the wings 1a and 1b are lowered to prevent passage of air. It is provided on the wings 1a and 1b.
[0017]
The opening / closing means 2a, 2b includes sheet-like or thin-plate-like blades 4a, 4b integrally connected to the sheet-like bodies 3a, 3b constituting the blades 1a, 1b, and the root portions 5a of the blades 4a, 4b. The free ends 6a and 6b are pivoted up and down with 5b as a fulcrum. Moreover, the free ends 6a and 6b are disposed so as to overlap the lower surfaces of the sheet-like bodies 3a and 3b constituting the wing.
[0018]
Accordingly, when the blades 1a and 1b are lowered, the blades 4a and 4b are closed by the resistance of the air, and when the blades are lifted, the blades 4a and 4b are opened by the force of the air. The blades 4a and 4b automatically open and close. As a result, the blades 4a, 4b constituting the opening / closing means 2a, 2b can be opened / closed so as to generate a levitation force on the blades 1a, 1b without special control.
[0019]
That is, when the wings 1a and 1b are lowered by human power or power, a force that rises by pushing down air over the entire surface of the wings 1a and 1b is generated, and the airframe can be easily raised. Further, when the blades 1a and 1b are raised and raised, the opening / closing means 2a and 2b are opened so that air can pass therethrough, so that the air resistance is reduced, and the blades 1a and 1b can be easily lifted with a small force. It can return to the next, and it can prepare for the next levitation operation, and the amount of lowering of the fuselage is small. The vertical movement of the wings 1a and 1b can use both human power and power.
[0020]
The opening / closing operation of the opening / closing means 2a, 2b can be performed by human power or power. However, by applying the check valve principle in the valve mechanism, the opening / closing means 2a, 2b are automatically operated by the air force when the blades 1a, 1b move up and down. If the opening / closing operation is performed, a special drive source is not required, so that the opening / closing control of the opening / closing means 2a, 2b is facilitated, the configuration is simplified, and the weight can be reduced.
[0021]
The bases of both wings 1a and 1b are pivotally supported on a main frame 8 on which the human body 7 is mounted and supported, and the wings 1a and 1b are rotated and raised about the above-mentioned shaft support portion. Elastic means for generating directional force, such as rubber strings 9a and 9b, are provided.
[0022]
Further, between the wing frame supporting each of the wings 1a and 1b and the drive unit by at least one of the arm force, leg force and mechanical force of the human 7 who is riding on the main frame 8, It is connected by connecting means 11a, 11b such as a bar.
[0023]
Therefore, the wings 1a and 1b of both of the humans 7 riding on the main frame 8 can be pulled down against the elasticity to generate a levitation force. .
[0024]
However, the connecting means 11a and 11b and the driving portion are improved as shown in FIGS. 1 and 2 according to the present invention.
[0025]
The one-way opening / closing means 2a, 2b is provided on both wings 1a, 1b. In addition, as shown in FIG. Similarly, the wings 12a and 12b are also unidirectional opening and closing means that opens when the wings 1a and 1b are raised and allows air to pass, and closes when the wings 1a and 1b are lowered so that the air cannot pass therethrough. 13a and 13b are provided. Therefore, as shown by P2 in FIG. 4 (d), it is possible to easily generate the propulsive force of the flapping flight device and to fly at a high speed.
[0026]
The oblique blades 12a and 12b having the unidirectional opening and closing means 13a and 13b can be rotated back and forth with respect to the blades 1a and 1b, and can be rotated back and forth independently of the blades 1a and 1b. It is also possible to do.
[0027]
In this case, since the inclined blades 12a and 12b can be rotated back and forth with respect to the blades 1a and 1b, the flapping operation of the blades 1a and 1b is stopped and the inclined blades 12a and 12b are stopped. If only forward and backward rotation is performed, only forward movement is possible. When the oblique blades 12a and 12b move in the thrust generation direction, the unidirectional opening / closing means 13a and 13b are closed, and when the oblique blades 12a and 12b move in the opposite direction, they are opened and air resistance is reduced. Propulsive force can be generated efficiently by 12a and 12b, and the forward movement is smoothly performed.
[0028]
The unidirectional opening / closing means 2a, 2b provided on both the wings 1a, 1b can be opened against the levitation force by the operation of the passenger, and the opening amount can be controlled. In addition, a configuration connected to the operation unit is also possible. In this case, by controlling the opening amounts of the opening / closing means 2a and 2b by the operation of the passenger, the descent speed and the landing operation can be freely controlled, and the operability is further improved.
[0029]
In the present invention, the connecting means 11a and 11b such as wire-like bodies and bars and the drive units 10a and 10b in FIG. 4 are improved to a bar having a bent structure as shown in FIGS. .
[0030]
In FIG. 4, the wings 1a and 1b are pivotally supported on one common shaft, but in FIGS. 1 and 2, two substantially parallel main frames 17a, It is pivotally supported by 17b.
[0031]
The main frames 17a and 17b are connected by a plurality of horizontal bridge-shaped frames 8c, and leg frames 8a and 8b extending downward are fixed to the main frames 17a and 17b. A horizontal lower frame 8d is connected and fixed so as to connect the lower portions of 8b. A support frame 8e for supporting a human body is fixed horizontally between the leg frames 8a and 8b.
Wheels 18a and 18b are attached to the lower ends of the leg-shaped frames 8a and 8b.
[0032]
Reference numerals 19a and 19b denote wing frames for stretching the sails 3a and 3b in FIG. 4, and the sail is not shown in FIG. Elastic means 9a, 9b such as rubber or tension coil springs are attached between the support column 20 extending upward from the main frames 17a, 17b and the wing frames 19a, 19b.
[0033]
Further, a bent bar is attached between the wing frames 19a and 19b and the horizontal frame 8d. The bent bar includes wing-side bars 22a and 22b whose upper ends are supported by the wing frames 19a and 19b by the axes A1 and A2, and main body-side bars 22c and 22d whose lower ends are supported by the horizontal frame 8d by the axes A3 and A4. It is made up of.
[0034]
The lower side of the wing side bars 22a and 22b and the upper ends of the main body side bars 22c and 22d are connected by axes A5 and A6, and can be bent at the positions of the axes A5 and A6. Therefore, the right wing side bar 22a and the main body side bar 22c in the drawing are referred to as a middle folding bar B1, and the left wing side bar 22b and the main body side bar 22d in the drawing are referred to as a middle folding bar B2. Needless to say, each of the axes A1 to A6 has a pivotable support structure.
[0035]
Elastic means 23a, 23b such as rubber or tensile coil sbling are attached between the upper ends of the main body side bars 22c, 22d and both ends of the horizontal frame 8d. Further, grip portions 24a and 24b for gripping with both hands are attached to the upper ends of the main body side bars 22c and 22d.
[0036]
Next, the flapping operation of the flapping flight apparatus will be described with reference to FIG. In FIG. 2, only the movements of the wing frames 19a and 19b, the wing side bars 22a and 22b, and the main body side bars 22c and 22d are shown. That is, the solid line indicates the position where the wing frames 19a and 19b are raised most, the broken line indicates the middle position, and the chain line indicates the position where the wing frames 19a and 19b are lowered most.
[0037]
The flapping operation of the wing frames 19a and 19b is performed by reciprocating left and right by grasping the grip portions 24a and 24b with both hands in a state where a human is placed on the support frame 8e of FIG.
[0038]
The wing frames 19a and 19b are pulled upward by the tensile elastic means 9a and 9b of FIG. 1, and the bent bars B1 and B2 are extended by the tensile elastic means 23a and 23b to push up the wing frames 19a and 19b. Acting in the direction. Therefore, in addition to this elasticity, when the grip portions 24a, 24b are gripped with both hands and pushed outward, both wing frames 19a, 19b are raised to the upper limit position as shown by the solid line. In this state, the bent bars B1 and B2 are in a state of extending straight, so that the wing frames 19a and 19b cannot rise any further.
[0039]
Next, when the grips 24a and 24b are pulled inward, the middle bent bars B1 and B2 are bent at the shaft support portions A5 and A6, and the both wing frames 19a and 19b are rotated and lowered to a broken line state. Subsequently, when the grip portions 24a and 24b are further pulled inward, the middle folding bars B1 and B2 are further bent, and the wing frames 19a and 19b are further pulled downward to rotate and lower to a lower limit position indicated by a chain line.
[0040]
Thus, when the grip portions 24a and 24b are pulled inward, the gripping portions 24a and 24b are pulled against the elasticity of the pulling elastic means 9a and 9b and the pulling elastic means 23a and 23b. Because it works, it requires great power. Further, levitation force acts on the blades 1a and 1b by the air resistance at this time.
[0041]
Next, when the grip portions 24a and 24b are pushed outward so as to expand, the folded bars B1 and B2 are gradually extended and straightened, so that the folded bars B1 and B2 and the wing frames 19a and 19b are Then, the wing frames 19a and 19b are moved upward from the chain line state to the broken line state and then in the order of the solid line state.
[0042]
When the blades 1a and 1b are turned up, the blades 4a and 4b of the opening and closing means 2a and 2b are opened as described with reference to FIG. However, upward air resistance acts on the region where the blades 4a and 4b do not exist, and the force in the direction of raising the blades 1-a and 1b by the tensile elastic means 9a, 9b, 23a and 23b. Therefore, when the blades 1a and 1b are lifted, they can be operated with a relatively small force.
[0043]
In the illustrated example, the main body side bars 22c and 22d are attached to the horizontal frame 8d. However, if the main body side frames are lower than the main frames 17a and 17b supporting the wing frames 19a and 19b, the main body side bars 22c and 22d are horizontal. It may be attached to other than the frame 8d. For example, it can be attached to the leg-shaped frames 8a and 8b. Accordingly, the lower frames connected to the main frames 17a and 17b are collectively referred to as a lower frame.
[0044]
The grip portions 24a and 24b may also be attached to the lower ends of the shaft support portions A5 and A6 and the wing side bars 22a and 22b.
[0045]
In order to reduce the weight, each frame is preferably composed of a hollow body or pipe made of glass fiber, carbon glass fiber, or the like.
[0046]
In addition, the opening / closing drive of the grips 24a and 24b can be performed by power such as a motor. FIG. 3 shows an example thereof, in which a link 26a is pivotally supported on an axis A7 provided on a gear 25a driven by power such as a motor, and a tip thereof is pivotally supported on a drive unit 24a. Further, the link 26b is pivotally supported on an axis A8 provided on the gear 25b that meshes with the gear 25a, and the tip thereof is pivotally supported on the drive unit 24b.
[0047]
The shafts A7 and A8 are provided at symmetrical positions with respect to the tangent at the meshing portion of the gear 25a and the gear 25b. Further, since the gear 25a and the gear 25b rotate in the opposite directions, both the gears 25a and 25b. The rotation of the drive units 24a and 24b causes the foldable bars B1 and B2 to expand and contract by moving the blades 19a and 19b up and down.
[0048]
【The invention's effect】
According to claim 1 , the lower frame and both wings are connected by a bar having a middle folding structure, and provided at a middle folding part (a connecting shaft supporting part between the main body side bar and the wing side bar) or at the upper end of the main body side bar or the lower end of the wing side bar. Since the grip means is held by both hands and both wings are moved up and down, the grip means does not move up and down, but reciprocates in a substantially horizontal direction. As a result, it is easy to apply force and it is difficult to get tired, so that a long flapping operation is possible.
[0049]
According to the second aspect of the present invention , since the center-folded bar composed of the main body side bar and the wing side bar has the elastic means in the direction of straightening, the elastic means is used to raise both wings. Force acts. Therefore, it is sufficient for the human power to generate a force in the direction of lowering both wings, that is, the direction of pulling the grip means against the elastic force of the elastic means.
[0050]
The elastic force by the elastic means and the upward air resistance acting on the wings cause a force in the direction in which the folding lever is straightened, so that a force for raising the wings is not so necessary.
