Because the vertical motion of the wings can be easily attained by a limited force, floating can be made efficiently and the flapping operation can be made for a long period of time. This flapping flying apparatus includes unidirectional opening/closing means provided to both wings for supporting right and left two rings in such a manner that they can flap in the vertical direction, opening to allow air to pass when they move up and closing to inhibit air from passing when they move; mid-point foldable structure for connecting for pivotal supporting a main body side bar pivotally supported by a lower frame disposed below support portions of both wings with wing side bars pivotally supported on the support frame side of both wings; and a driving portion such as gripping means disposed near a connecting portion between the main body side bar and the wing side bar.

Description

Description Flapping flight equipment Technical field

TECHNICAL FIELD The present invention relates to a flapping flight device that generates a levitation force by moving a pair of wings up and down, and particularly to a flight device that flutters a wing manually.

The inventor of the present invention disclosed in Japanese Patent Application No. 5-1770778 that the efficiency of the wings was improved by providing unidirectional opening / closing means on the wings that flutter up and down and close when the wings descend and open when the wings rise We proposed a device that generates levitation force and flutters manually or with auxiliary power.

However, the previous invention has a structure in which a grip portion is provided on a bar connected to the wing in order to move the wing up and down, and the grip portion is moved up and down with both hands.

According to this structure, it is necessary to move the grip portion up and down and the bird wings to flutter, so that the force for moving the wings up and down is difficult to enter, and it is easy to get tired. Therefore, it is difficult to levitate, and it is difficult to flutter for a long time.

The technical problem of the present invention is to focus on such a problem and to make it possible to easily lift and lower the wing with a light force, thereby enabling efficient levitation and long-time flapping operation. It is in. Disclosure of the invention

The technical problem of the present invention is solved by the following means.

In the first invention, the two left and right wings are supported so as to be capable of flapping up and down, open when both wings rise, and allow air to pass through, and when both wings descend, close to disable air passage. In a flapping flight system in which a unidirectional opening / closing means is provided on both wings, a main body side bar supported on a lower frame provided below the supporting portions of both wings, and a supporting bar provided on the supporting frame side of both wings. A flapping flight device comprising a wing-side bar connected to the wing-side bar and having a structure capable of being bent in the middle, and a driving unit such as a gripping means provided near a connecting portion between the main-body-side bar and the wing-side bar.

In this way, the lower frame and the two wings are connected by a bar with a middle bent structure, and the gripping means provided near the center bent part is held with both hands to move the two wings up and down. Instead of making them move, they reciprocate almost horizontally. As a result, it is easy to apply power and it is hard to get tired, so that long-time flapping can be performed.

The second invention is a flapping flight device having elastic means for generating a force in a direction in which the main body side bar and the wing side bar in the first invention are straightened by elasticity.

As described above, since the bar having the middle bent structure composed of the main body side bar and the wing side bar has the elastic means in the direction of straightening, a force in the direction of raising both wings is exerted by this flexible means. .

Therefore, it is sufficient for the human power to generate a force in the direction of lowering the two wings, that is, in the direction of pulling the gripping means, against the elasticity of the elastic means, so that the force for generating the levitation force is easily applied.

The elasticity of this elastic means and the upward air resistance acting on the wing Due to the fact that the straight bar works in the direction of straightening, the wing lift force is not very necessary. BRIEF DESCRIPTION OF THE FIGURES

Next, an embodiment will be described as to how the flapping flight device according to the present invention is actually embodied. 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 of the flapping flight device.

The flapping flight device of the present invention is an improvement of the flapping flight device of the previously filed Japanese Patent Application No. 5-1770778. I do.

In FIG. 4, (a) is a plan view showing the entirety of the flapping flight device according to the present invention, (b) is a sectional view taken along the line b-b in (a), and (c) is c in (a). FIG. 1C is a cross-sectional view, and FIG. Reference numerals 1a and 1b denote left and right wings, which have a structure in which sails made of sheet slats 3a and 3b are stretched on wing frames and supporting wires (not shown). The wings 1a and 1b are lifted up and down manually or by power to generate a levitation force.

However, when the two wings 1a, 1b rise, they open to allow air to pass through, and when the two wings 1a, 1b descend, they close to prevent air from passing. 2b is provided on both wings la and lb.

The opening / closing means 2a, 2h are composed of sheet-like or thin sheet-like blades 4a, 4b integrally connected to the sheet-like bodies 3a, 3b constituting the wings 13, 1b. The free ends 6a and 6b are configured to pivot up and down around the roots 5a and 5b of the blades 4a and 4b. In addition, the free ends 6a and 6b are arranged so as to overlap the lower surfaces of the sheet-like members 3a and 3b constituting the wing.

Therefore, when the wings 1a and 1b descend, the blades 4a and 4b close due to the resistance of air, and when the wings 1a and 1b rise, the blades 4a and 4b open with the force of air. The blades 4a and 4b open and close automatically in conjunction with the vertical movement of b. As a result, the opening / closing operation can be performed so as to generate a levitation force on the blades 4a, 4 1) and the blades 13, 1b constituting the opening / closing means 2a, 2b without performing special control.

That is, when the wings 1a and 1b are lowered by human power or power, a force is generated that pushes down the air over the entire surfaces of the wings 1a and 1b, and the aircraft can be easily lifted. When the wings 1a and 1b are returned and raised, the opening / closing means 2a and 2b are opened to allow air to pass through. , 1b can be raised and restored to prepare for the next levitation operation, and the amount of descent of the aircraft is small. In addition, wing la, lb It is possible to use both human power and power for vertical movement.

The opening / closing operation of the opening / closing means 2a, 2b can be performed manually or by power.However, by applying the check valve principle in the valve mechanism described above, the air when the blades 1a, lb move up and down is applied. With a configuration that automatically opens and closes with this force, no special drive source is required, so that the opening and closing control of the opening and closing means 2a and 2b is facilitated, and the configuration is simplified and the weight can be reduced.

The roots of both wings 1 a and 1 are rotatably supported on a main frame 8 on which the human body 7 is mounted and supported, and the respective wings 1 a and 1 b rotate around the shaft support. It has elastic means for generating a force in the direction of moving up, for example, rubber strings 9a and 9b.

In addition, the wing frame supporting each wing 1a, 1b and the drive unit of at least one of the arm strength, leg strength and mechanical force of the person 7 riding on the main frame 8 , And connecting means such as a wire-like body and a bar.

Therefore, the wings 1a and lb of both wings may be pulled down by the strength, leg strength, mechanical strength, and the like of the person riding on the main frame 8 against the elasticity to generate a levitation force. it can.

However, the connecting means lla, lib and the driving section are improved by the present invention as shown in FIGS.

The one-way opening / closing means 2a and 2b are provided on both wings la and 1b, and additionally, as shown in FIG. 4 (c), at the tips of both wings 1a and 1b. Similarly, when the wings 1a and 1b rise, the open wings 1a and 1b open and allow air to pass through, and when the wings 1a and 1b descend, they close and close. One-way opening / closing means 13a and 13b for preventing air from passing are provided. Therefore, as indicated by P2 in Fig. 4 (d), Can easily generate thrust and fly at high speed.

In addition, the inclined blades 12 a and 1213 having the one-way opening / closing means 13 a and 13 b can rotate back and forth with respect to the blades 13 and 1 b, and the blades 1 a and lb. Can be independently rotated back and forth.

In this case, since the inclined blades 1 2a and 1 2 13 can rotate back and forth with respect to the blade 13 and lb, the flapping of the blades 1 a and 1 b, for example, when riding in an updraft, Stopping, if only the forward and backward rotation of the inclined wings 12a and 12b is performed, only forward movement is possible. When the inclined wings 12a and 12b move in the thrust generating direction, the one-way opening / closing means 13a and 13b are closed, and when moving in the opposite direction, open. Since the air resistance is reduced, the propulsion force can be efficiently generated by the inclined blades 12a and 12b, and the forward motion is smoothly performed.

One-way opening / closing means 2a, 2b provided on both wings 1a, 1b are constructed so that they can be lifted and lifted by operating the occupant, and the amount of opening It is also possible to have a configuration linked to the operation unit so that the control can be performed. In this case, the descending speed and the landing operation can be freely controlled by controlling the opening amounts of the opening / closing means 2a and 2b by the operation of the passenger, and the operability is further improved.

In the present invention, a connecting means 11a, 111) such as a wire-like body or a bar in FIG. 4 and a drive unit 10 &, 10b are connected to each other by a folding structure as shown in FIGS. The bar has been improved.

In FIG. 4, the wings 1 a and lb are rotatably supported by one common shaft, but in FIGS. 1 and 2, two substantially parallel main frames 1 It is supported on 7a and 17b.

Multiple horizontal bridge frames between the main frames 17a and 17b 8c, and legged frames 8a, 8b extending downward are fixed to both main frames 17a, 17b, connecting the lower parts of legged frames 8a, 8b So that the horizontal lower frame 8d is connected and fixed. A support frame 8e for supporting a human body is fixed horizontally between the leg-shaped frames 8a and 8b. Wheels 18a, 18b are attached to the lower ends of the leg-shaped frames 8a, 8b.

19b is a wing frame for extending the sails 3a and 3b in FIG. 4, and the sail is not shown in FIG. Elastic means 9a, 9 such as rubber or tension coil springs are provided between the struts 20 extending upward from the main frames 17a, 17b and the wing frames 19a, 19b. b is attached.

Also, a center bending bar is attached between the wing frames 19a and 19b and the horizontal frame 8d. The center bending bar has wing side bars 22 a and 22 b supported at the upper ends by wing frames 19 a and 19 b on axes A 1 and A 2, and the lower end by a horizontal frame 8 on a horizontal frame 8. 3, consists of main body side bars 22c and 22d supported by A4.

The lower ends of the wing-side bars 22a and 22b and the upper ends of the body-side bars 22c and 22d are connected by axes A5 and A6, and the positions of the axes A5 and A6 Can be folded in. Therefore, the wing-side bar 2 2a on the right side of the figure and the main body side bar 2 2c are referred to as a center bending bar B1, and the wing-side bar 2 2b on the left side of the figure and the main body side bar 2 2d are bent in the middle. Call it B2. Needless to say, each of the shafts A1 to A6 is a rotatable shaft support structure. Elastic means 23a and 23b, such as rubber and tension coil springs, are attached between the upper ends of the body side bars 22c and 22d and both ends of the horizontal frame 8d. Also, on the main unit side 2 2c and 2 2d At the end, grips 24a and 24b for holding with both hands are attached. Next, the flapping operation of the flapping flight device will be described with reference to FIG. In FIG. 2, only the movement of the wing frames 19a and 19b, the wing-side bar-22a. 22b, and the main body-side bar 22c and 22d are shown. In other words, the solid line shows the position where the wing frames 19a and 19b rise most, the broken line shows the middle position, and the chain line shows the position where the wing frames 19a and 19b fall most. .

The flapping motion of the wing frames 19a and 19b is performed by holding the gripping portions 24a and 24b with both hands while the human is lying on the support frame 8e in FIG. It is performed by reciprocating left and right.

The wing frames 19a, 19b are pulled upward by the tension elastic means 9a, 9b shown in FIG. 1, and are also bent B1, B by the tension elastic means 23a23b. 2 acts to extend the wing frames 19a and 19b by extending them. Therefore, in addition to this elasticity, when the grip portions 24a and 24b are grasped and pushed outward with both hands, the two-wing frame 19a.19b rises to the upper limit position as shown by the solid line. In this state, the center folding bars Bl and B2 are in a straightened state, so that the wing frames 19a and 19b cannot further rise. Next, when the grips 24a and 24b are pulled inward, the center bending bars B1 and B2 break at the shaft supports A5 and A6, and the two wing frames 19a and 19b rotate. It descends and becomes a broken line. Subsequently, when the grip portions 24a and 24b are further pulled inward, the middle bent bars Bl and B2 are further bent, and the wing frames 19a and 19b are further pulled downward, and the chain line Rotate down to the lower limit position shown by.

When the grips 24a and 24b are pulled inward, the elasticity Means 9a and 9b and tensile elastic means 23a and 23b are pulled against the elasticity, and a large force is required because air resistance acts on the entire lower surface of both wings la and lb. At this time, levitation force acts on the wings 1a and 1b due to the air resistance.

Next, when the grip portions 24a and 24b are pushed outward so as to be expanded, the middle bending bars Bl and B2 are gradually pushed and stretched straight, so that the middle bending bars B1 and B1 B2 and the wing frames 19a and 19b move from the chain line state to the broken line state, and then to the solid line state, and the wing frames 19a and 19b rotate upward.

When the two wings l a and 1 b rotate upward, the blades 4 a and 4 b of the opening / closing means 2 a and 2 b open as described in FIG. 4, and the air resistance decreases. However, in the area where the blades 4a and 4b are not present, upward air resistance acts, and in addition, the tensile elastic means 9a, 9b, 23a and 2313 Since the force in the direction of raising the wings 13 and 1b is acting, when the wings 1a and 1b are raised, it can flutter with relatively small force.

In the illustrated example, the main body side bars 22c and 22d are attached to the horizontal frame 8d, but the main frames 17a and 17 that support the wing frames 19a and 19b If it is the main body side frame below b, it may be attached to other than the horizontal frame 8d. For example, it can be attached to the leg frames 8a and 8b. Therefore, the lower frames connected to the main frames 17a and 17b are collectively called lower frames.

The grips 24a and 24b may also be attached to the lower ends of the shaft supports A5 and A6 and the wing-side bars 22a and 22b. In order to reduce the weight, each frame is preferably made of a hollow body or pipe made of glass fiber, power glass fiber, or the like.

In addition, the opening / closing drive of the grip portions 24a and 24b can be performed by power of a motor or the like. Fig. 3 shows an example, in which a link 26a is pivotally supported on a shaft A7 provided on a gear 25a driven by a motor or the like, and a distal end of the link 26a is pivotally supported on a driving section 24a. . Further, a link 26b is pivotally supported on a shaft A8 provided on the gear 25b meshing with the gear 25a, and a tip of the link 26b is pivotally supported on the driving portion 24b.

The shafts A 7 and A 8 are provided at symmetrical positions with respect to a tangent line at a meshing portion between the gear 25 a and the gear 25 b, and the gear 25 a and the gear 25 b are different from each other. Since the two gears 25a and 25b rotate in opposite directions, the drive units 24a and 24b open and close to the left and right by the rotation of the two gears 25a and 25b. The wing frames 19a and 19b can be moved up and down by expanding and contracting the wing frames. Industrial applicability

According to the first invention, the lower frame and the two wings are connected by a bar having a middle bent structure, and the grip means provided near the middle bent portion is gripped with both hands to move the two wings up and down. The means are not moved up and down, but reciprocated almost horizontally. As a result, it is easy to apply power and it is hard to get tired.

Further, according to the second invention, since the bar of the center-bending structure composed of the main body side bar and the wing side bar has the elastic means in the direction of straightening, the two wings are raised by this elastic means. Directional force acts. I Therefore, human power is sufficient to generate force in the direction of lowering both wings, that is, in the direction of pulling on the gripping means, by staking the elasticity of this elastic means, and the force at the time of generating levitation force is included. easy.

Since the elasticity of the elastic means and the upward air resistance acting on the wing exert a force in the direction in which the center bending bar straightens, the force required to raise the wing is not so necessary.

Claim 1 has a structure in which the main body side bar and the wing-side bar are bent inward toward the inside, and when both wings are raised due to air resistance acting on both wings, the wing-side bar with the middle bent structure is used. Clarified that the main body side bar extends straight down.

In the cited example (US, 4, 417, 70,), the operation in the directions of arrows a3 and a4 is performed by the elastic means 23a and 23b such as rubber in FIG. In addition, the wing-side bar and the body-side bar cannot be stretched in a straight line, and no force can be applied to push the wing upward.

In the cited example (JP, 7-33092), the connecting rods 35a and 35b have a structure that bends outward, so it is necessary to apply force to push down both hands, and it is difficult to exert enough force to pull down the wing . Conversely, when raising the wings, both arms must be raised, but also in this case, it is difficult to exert power.

On the other hand, according to the present invention, the wing-side bar and the main-body-side bar are constituted by bars, not wires, and the wing-side bar and the main-body-side bar are linearly extended by rubber or the like to apply a force for pushing up the wing. Becomes possible.
