[Prior art]

 Flying toys that use the principles of airplanes and helicopters are well known, and it is also well known that rubber, springs, engines, and electric motors are used as the power source for propellers that generate propulsive force and rotors that generate lift. Is.

Among these flying toys, those using an engine or an electric motor as a power source are intended for school children and students of higher grades and adults, and require a vast space. Also, the one powered by rubber or rubber is suitable for school children of lower grades and children who are close to school, and since it has considerable flight ability, it requires a sufficiently large space.

On the other hand, as a flying toy suitable for infants and children who do not have the knowledge to handle engines and electric motors, but also have the operating ability to store sufficient rubber and springs, they can be projected with one hand and fly like a glider. There are paper airplanes that can be made to fly, and bamboo dragonfly that holds the shaft between both hands to rotate and release it.However, since it only makes it fly by applying its own force, the flight distance and time are extremely short. Or, there is a problem that it is difficult to make people interested because it has the same shape and design as existing flying objects.

[0005]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to use a rubber and a spring as a power source, which has a flight ability that cannot be obtained by hand power, and which has a shape and design that is easy to operate even for small children and infants and that does not lose interest. The point is that there was no flying toy that I had.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a rod-shaped body between a hanging position on both sides near the upper end and an expanding position extending substantially at right angles to the body and in opposite directions. A flying body in which two wings are attached to rotate freely, and a holding cylinder is rotatably attached to the lower end of the main body; a reel in which an operation string having a tab is wound around the tip and the base end is fixed. , A rewinding power member that accumulates rotational force in the winding direction as the reel rotates in the feeding direction, a driving mechanism that has a speed increasing gear for transmitting the rotation of the reel to the flying body, and a one-handed grip and hold It consists of a housing that has a guide tube that is open to the top surface where the cylinder is fitted. The knob is locked to the outer surface of the housing, and the tip of the drive shaft that supports the driven side of the speed increasing gear faces the guide tube. The housing It consisted of; the promotion vessel was built; a lower end and bonding and separation free shaft coupling in the axial direction provided at the upper end of the drive shaft of the main body.

Further, in the above, the aircraft is made into a doll form by a wing formed by attaching wings to the main body composed of a head and an elongated torso and legs up and down and arms, and the wings are directed toward the rotation direction of the aircraft. Inclining upward and softening at least the peripheral part, making the housing self-supporting, providing a constriction part as a grip in the middle part, and incorporating a driving mechanism in the upper part, linking the aircraft and the thruster with each other It is preferable to unify the shapes and designs of certain objects.

[0008]

[Action]

 Insert the holding tube into the guide tube to connect the shaft coupling, hold the housing with one hand in an upright posture, and hold the knob with the other hand to pull the operating cord to reel. Rotates and the operating axis is driven at high speed, and the aircraft rotates.

【Example】

 Referring to the drawings, an embodiment of the present invention will be described. An aircraft A is made of synthetic resin in the form of a female dancer doll, and has a head 2 and a torso 3 elongated vertically. A bar-shaped main body 1 as a whole including legs 4, and wings 5 formed by attaching left and right arms 6 rotatably attached to a shoulder of a body 2 by a support shaft 8 to wings 7 extending forward thereof. And have.

In FIG. 1, the left and right wings of the two wings 5 are shown in the drooping position and the right arm, respectively, in an expanded position toward the front of the doll. A stop pin 9 is provided on the side of the support shaft 8 projecting from the base end of the arm 6 so as to rotate between the expanded position extending in the opposite direction and the shaft hole 10 of the main body 1. The stop pin 9 was fitted in the circular arc groove 11 formed on the peripheral surface to regulate the turning range (see FIG. 2).

Further, as can be seen from the right arm of FIG. 1, the wing 5 is inclined upward toward the front in the direction of rotation given by a propulsion device B, which will be described later, of the air vehicle A, which creates an angle of attack. , Always generate lift.

Further, the arm 6 and the blade 7 are integrally molded of hard synthetic resin, and the cushion layer 15 made of soft rubber is laminated on the peripheral edge portion and the upper surface of the blade 7 to prevent damage when hitting a hard object. Not only will they not be injured, but they will not be injured if they hit the human body.

A support shaft 12 made of metal is fixedly protruded below the leg 4 of the main body 1, and a clutch piece 43 of a dog clutch forming a shaft coupling C, which will be described later, is fixedly fixed to the tip portion thereof. . A small-diameter pipe portion 14 at the base end of a holding cylinder 13 made of synthetic resin that surrounds the clutch piece 43 and extends below the tip end thereof is rotatably fitted on the support shaft 12.

Next, the propulsion device B has a lower base 23 whose bottom surface 22 is flat so as to be self-supporting, and a grip portion 24 which is narrowed to a thickness that can be held by one hand by a small child in an intermediate portion. And a large-enlarged storage part 25 at the top, and has a hollow housing 21 made of synthetic resin.

The housing 21 is made up of flowers and leaves studded with trees to form a suitable place for a dancer to take off. However, celestial bodies such as the moon and stars, sea animals such as fish and dolphins, etc. It is preferable to have a shape and design that are related to Aircraft A in order to keep the fun.

A casing 30 made of synthetic resin, which houses a driving mechanism 31, is built in and fixed to the storage portion 25. The driving mechanism 31 includes an operating cord 33 having a butterfly-shaped knob 32 attached to the tip thereof, a reel 35 fixed to a support shaft 34 having both ends rotatably supported by the casing 30, and a support shaft. A rewinding power member 36 formed of a torsion coil spring surrounding 34, a drive shaft 37 having one end fixed to the casing 30 and being supported in a cantilever manner, and a drive shaft 37 arranged in parallel with the support shaft 34, and an interlocking mechanism between them. And a speed gear 38.

The operation string 33 has its base end fixed to one flange of the reel 35, extends in the lateral direction, and is drawn out to the outside of the storage section 25 through the through hole 26 of the housing 21. The piece 32 is locked to the outer surface of the housing 21 so as not to be pulled in.

One end of the torsion coil spring that constitutes the rewinding power member 36 is fixed to the casing 30 and the other end is fixed to the other flange of the reel 35, and the operation string 33 is always wound around the reel 35. Applying rotational force in the direction.

The support shaft 34 and the drive shaft 37 extend in the vertical direction, and the flange to which the operation string 33 of the reel 35 is fixed is used as the large gear 40 on the driving side, and the driven side is rotatably fitted to the drive shaft 37. The speed of rotation of the reel 35 is increased by the speed increasing gear 38 configured to mesh with the small gear 41 of FIG.

Further, the shaft coupling C is composed of a triangular chevron-shaped meshing clutch, and is fixed to the tip of the support shaft 12 of the flying body A and is placed inside the holding cylinder 13 and is provided with a downward clutch on the driven side. Upward of the driving side disposed inside the guide tube 27 formed integrally with the gear piece 43 and the small gear 41 of the driving mechanism B, which is rotatably fitted to the tip of the drive shaft 37 and projectingly formed in the casing 30. When the operation cord 33 is pulled out and reeled out from the reel 35, the clutch clutch 42 on the driving side pushes the clutch clutch 43 on the driven side to rotate the flying body A. However, the driven side separates at higher speeds.

The guide cylinder 27 is opened to the upper surface of the housing 21 and holds the holding cylinder 13 with a slight slack to hold the aircraft A in an upright state. The guide cylinder 27 is provided not in the casing 30 but in the housing 21. Sometimes.

In this embodiment having such a configuration, the holding barrel 13 of the flying body A is fitted into the guide barrel 27 so as to be held upright on the upper surface of the propulsion unit B. Further, if the clutch pieces 42 and 43 are pushed in at the time of fitting, they will rotate and descend to mesh with each other. Alternatively, in the present embodiment, since the clutch pieces 42, 43 are triangular in shape, even if they are left unattended, they are rotated by the own weight of the flying body A and descend to mesh with each other (see (1) in FIG. 3).

Next, when the operator grasps the grip portion 24 of the housing 21 with one hand and holds the flying body A upright or in a slightly tilted position with the other hand and holds the knob 32, the operation cord 33 is pulled. The reel 35 rotates while feeding out the operation string 33, rotates the drive shaft 37 at a high speed through the speed increasing gear 38, and twists the rewinding power member 36 to accumulate a rotational force in the winding direction.

The wing 5 of the flying body A, which is connected to the drive shaft 37 by the shaft joint C, generates a lift force with the rotation and is rotated and raised to the expanded position, and then the main body 1 is lifted. . In order to generate a lift force capable of raising the main body 1 on the wing 5, it is necessary to rotate at a considerably high speed, and therefore the operation cord 33 must be pulled at a considerably high speed and at a constant speed. However, the procedure can be easily learned with one or two mistakes, and thereafter, the operation cord 33 can be pulled to a high place by pulling at a maximum speed and stroke that does not break the operation cord 33.

When the main body 1 starts to rise while rotating, the shaft coupling C separates as shown in (2) of FIG. 3, and subsequently the holding cylinder 13 comes out of the guide cylinder 27 as shown in (3) of FIG. , Flying while rotating upward. It is the same as the bamboo dragonfly that the two wings 5 projecting from the rod-shaped body 1 in opposite directions generate lift with rotation, which is the same as the bamboo dragonfly, but in this embodiment, a dancer with wings 7 spins in the air. While appearing to dance (see Figure 4). Then, the blades 5 gradually hang down while descending as the rotation speed decreases, stall, and fall to the ground surface or floor surface.

In this embodiment, since the soft cushion layer 15 is provided on the peripheral portion and the upper surface of the blade 7, the wing 5 is not damaged by the impact at the time of dropping, and the human body is not touched during rotation. Will not be injured.

The rewinding power member 36 causes the operation string 33 to be wound up by rotating the reel 35 in the reverse direction when the flying body A starts flying and releases the knob 32 from the hand or stops pulling. It may be composed of a spiral spring or a rubber cord.

[0028]

[Effect of device]
