Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flying top toy having one flat body and at least one flat extension having an open-ended wing-shaped cross section, and a method of launching the toy.

It is known that objects that rotate around an axis at high speed have a very high degree of position stability. This is used as an example to give stable flight characteristics in the "Frisbee" disc known to everyone. However, this principle is valid not only for rotationally symmetric objects, but also for the highly curved "Bou-Melange" used by Australians as an example for hunting purposes.

Such a Bou-Melan has the additional advantage that it can be recaptured in the ideal case by changing its flight direction and returning by this generally asymmetric flying object. . For this reason, Boomerang, as opposed to the Frisbee discs, is a very nice toy that can be thrown away, caught again and enjoyed without boredom, even when there is no opponent.

On the other hand, since both toys have very long flight trajectories, they are "frisbee" discs,
Also, a large open site is required to play in Bou-Melang.

However, in a large city, such a large site is very rare, and children raised there are often prevented from playing with this fun flying toy.
Even if there is a sufficient site, frisbee or boomerang throwing can be played only outdoors, so it is premised on reasonably good weather rather than gusty weather.

For this reason, even in a narrow space,
In particular, there arises a problem which is a starting point of the present invention in which a flying top-shaped toy is formed so that it can be played indoors so that even children raised in a large city can enjoy the toy.

In the same type of toy, this problem can be solved by having the center of gravity of the flat body within this or within a distance of not more than 2 cm, preferably 1 cm or more.

Like the "Frisbee" disc, the Bou-Melan grabs its surroundings by hand and throws it with a powerful arm movement while shaking it greatly, and at that time, the Bo-Melang throws at high speed, which is important for flight stability. Be led to. At the same time, strong momentum is also generated in the flying toy, which causes the flying toy to fly away at high speed, causing serious damage to the obstacle when it collides with an obstacle, and in some cases, the flying toy is broken. Is inevitable.

This flight characteristic, which is unfavorable for play in a narrow space, arises from the momentum energy produced at launch, so that the flying toy according to the invention has another principle, namely that the flying toy is within the center of gravity on a stationary object. It is supported and expelled approximately tangentially at at least one peripheral point, whereby a large torque is launched by directing this light object into a high-speed turning movement, without the simultaneous flight momentum being so great.

This is due to the fact that the mass inertia of the flying object according to the invention is relatively large compared to its inertial moment, so that a large proportion of the simultaneous energy is translated into rotational movement and only a relatively small portion is translated. Achieved by flowing into exercise. This results in less inertial moments, but is caused by the profile of the flying top with wing extensions leading to the peripheral tips that contribute to the mass inertia of the object.

What is of decisive importance for the invention is that the mass of the peripheral region is very low with respect to the center of gravity, while the mass of the toy according to the invention is concentrated in its center of gravity. is there. This is "frisbee" as an example
The disc has a rounded end that surrounds the circumference, while the winged extension holds the open ends. In other flying toys, multiple winged extensions are connected to each other by a peripheral ring and are thereby stable, while the present invention eliminates this ring to minimize inertial moments.

Furthermore, the open end of the wing extension is of crucial importance for the launching of the flying toy according to the invention, since it is almost impossible to utilize the tangential torque in the annular arrangement.

By virtue of the fact that the bottom surface of the flat body, together with all the extensions formed therein, is defined by a smooth curve, no peripheral reinforcing elements are necessary. This guides one or more extensions into the plane without scoring,
Flying toys according to the invention will have a relatively high degree of stability, especially in the wing area, and will not require a peripheral ring or the like to stabilize the flying toy. What also contributes to the stability of the flying toy according to the invention is that the wing-like extension has a cross-section that is almost or not thin relative to the cross-section of the peripheral region at the point where it is guided to the center-of-gravity region of the plane. is there.

The fact that the planar bodies have a diameter of 2 to 10 cm further increases the self-stability of the arrangement according to the invention. With such a small diameter, the forces acting on the wing extension during flight are relatively small, which eliminates the need for peripheral stabilization.

In the present invention, the thickness of the flat body is further changed from 0.1 to 3 m.
m, preferably 0,2 to 1 mm, in particular 0,3 to 0.7 mm.
The required thickness is based in particular on the stability requirements for the flying toys according to the invention and possibly also manufacturing engineering factors.

Mainly light, stable construction materials, in particular plastics, are suitable for flying toys according to the invention. Such plastics are already anticorrosive by themselves without processing, which minimizes manufacturing costs. The coloring to the desired color can be adjusted, for example, by adding a pigment to the granular raw material, so that it is not necessary to dye it at a later date. By choosing the proper materials, it can be guaranteed to be free of toxic substances, so that even if a child puts such a toy in his mouth, it does not pose any danger to the child. Furthermore, the diameter of the object according to the invention has been consciously measured so that it cannot be swallowed.

The invention further provides the possibility of being manufactured from a rigid foil that is especially perforated with a planar wing extension. Since this manufacturing method is based on a foil-shaped intermediate product, the manufacturing process can be carried out with simple tools, which makes it possible to manufacture at very low costs.

A further concept of the invention in which the one or more wing extensions extend approximately radially far from the plane center of mass utilizes the fact that the shortest connection between two points is a straight line. While the wing extension extends almost radially, the wing periphery is connected to the center of gravity of the flying toy with very little material and thus very little inertial moment.

In the present invention, it is also possible to provide one or more winged extensions with a curved and splayed bottom surface.
Due to the fact that the wing extension is bent in its peripheral region, for example, the lift force generated there is strengthened because the bent wing region is an extension of the wing cross section there. Flight characteristics,
Especially when there are many wings to improve flight stability,
The wings should all be bent in the same swirl direction, the main direction of rotation.

While the plane of the wing extension or extensions is slightly inclined with respect to the plane of the plane, like a propeller, the toy according to the invention accelerates the molecules of the ambient air downwards, The ton's reaction principle makes it possible to obtain at all times during flight the rotational energy for producing a lifting force to support its own weight, which allows the toy according to the invention to float in the air even at very low translational speeds. It will be possible.

This results in the best low speed flight characteristics, such as helicopters, which are very important in enclosed spaces. The inclination of the extension with respect to the plane of the plane is 5 ° to 30 °, preferably 10 ° to 20 °.

The inclination of the wing extension or extensions with respect to the plane base plane can be set by deforming the plastic foil. This can be achieved, for example, by heating the perforated body at least partly, which causes it to become temporarily plastic and to be forced into the shape during the subsequent cooling.

The flight characteristics of the toy according to the invention depend on a number of ancillary conditions, especially because fluid technology factors have to be taken into account. Therefore, a flat body of any shape with one wing extension does not have flight capability. The inventor continued the experiment, and designed each category of the air vehicle that showed particularly advantageous flight characteristics.

In the first embodiment, approximately
There are flat extensions 10 ° to 90 °, preferably 30 ° to 90 ° aft. This extension serves to stabilize the position of the lift wing, which has its original, preferably long, shape, thereby producing stable flight conditions. This embodiment has the advantage of requiring only one lift wing and one additional stabilizing wing, which can further reduce inertial moments. In this case, a large torque is generated in the relatively long lift wing, which leads to a very strong rotational movement of this arrangement, which can receive a large amount of rotational energy at the time of launch, which causes it to float in the air for a very long time. It becomes possible.

Another type of flyable toy features a number of winged extensions that are rotationally symmetric with respect to the center of gravity of the planar body or are arranged in a mirror image about an axis passing through the center of gravity. In this embodiment, the flying toy achieves stable flight characteristics due to its symmetrical outer shape, with the advantageous center of gravity being approximately in the center of the plane.

The flight characteristics of the rotationally symmetric embodiment can be further completed by trying to move away from the center of gravity of the planar body while the wing extensions are placed opposite each other at the same angle. This results in a substantially star-shaped arrangement, but the individual rays can also be curved.

In this embodiment, since the central part does not produce a lift action, a central recess is provided which encloses the center of gravity surrounded by the closed ring of the planar body. The closed annulus interconnects and stabilizes the different airfoil extensions so that the central portion can be left almost unloaded, which further reduces the inertial moment of the array. Furthermore, the annular design allows the blades to be separated from each other almost exclusively because the individual blades are connected to each other only by a small cross section of the annulus, which allows the blades to be tilted in a very simple manner. Can be provided.

This is achieved, for example, by tangentially corrugating the planar body in a closed annulus. This corrugation causes the wings installed there to gain a corresponding actuation that creates lift in flight.

The wave number of the closed annulus corresponds to the number of blade extensions, and the tilt angle of the installed airfoil element can be adjusted by the phase shift of the blade origin with respect to the wave of the closed annulus.
The deformation of the airfoil elements is then unnecessary in itself, which makes it possible to achieve a high degree of symmetry of the arrangement with simple production tools.

By placing the flat body on the convexly curved surface in the vicinity of the center of gravity, especially on the middle joint of the finger, or the like, and flipping the flat body almost horizontally with respect to the flat body extension, the high speed rotation is achieved. The propeller-like action of one or a plurality of extensions causes a vertical transport force and a stabilizing force to stabilize the position, and the flying force according to the present invention is launched by jumping to a substantially horizontal acceleration force.

This system is adapted to the operation of a flying top in a room. Because very slow translational motion is desired,
The flying top according to the invention is repelled only at the peripheral extremities, the translational movement of the horizontally acting acceleration force being relatively small, while the large torque acting here provides a very fast rotational movement. This is achieved by the well-defined wing shape which results in very little inertial moment in the lift-producing part of the plane. Other features, details, advantages and operations according to the present invention will be described with reference to the following main embodiments of the present invention and the drawings.

The flying top 1 is shown in full size in FIG. This top is made of a plastic film about 0.2 mm thick and is therefore very light. Its weight is only about 0.5 g. This top is 1 for each center point of the ring
It has a ring-shaped body 2 with three winglike extensions 3 arranged 20 ° apart. Like the ring 3, the wing extension 3 also has a width of approximately
It is from 0,6 to 1,0 cm. The wing extension 3 first extends radially outward in the transition zone 4 for the annulus 2, then gradually bends at about 90 ° and extends approximately coaxially with the annulus 2 in the outer zone. This extension finally extends to the tip 5 of the blade, which is each defined by a semicircular curve. The flying top 1 retains the main direction of rotation 7 from the open end 5 of the wing 3 to approximately its origin 4.

The entire periphery 6 of the air vehicle 1 extends very smoothly and is very rounded, especially in the transition zone 4, so that there are no notches which adversely affect the stability. Ring 2 has a waveform with an approximately sinusoidal amplitude that is periodic around it, and the wave period corresponds to one-third of the circumference of the ring, which makes it Three corrugations are formed. The waveform of ring 2 is for the wing 3 and the front surface 8 of each wing-shaped origin 3
There is a maximum value 9 of the wave amplitude in each of the rotation directions 7 at, and the back surface 10 is out of phase so that the minimum value 11 follows it.

For this reason the ring 2 is in front of the wing in the transition zone 4.
It tilts downwards from 8 to its back surface 10 and this tilt continues to the tip 5 of the otherwise flat wing 3.

This causes the entire wing 3 to tilt in the opposite direction to the swirl direction 7, ie downwardly from its origin 4 of the annulus 2 to the open end 5. When the flying top 1 rotates at high speed in the direction of the arrow 7, the wing extension 3 pushes the cut air downward, which causes the flying top 1 to simultaneously lift in the opposite direction. Due to the very low weight and the very small cross section of the flying top 1, this top floats in the air for a very long time, and at a constant altitude for a long time.

The diameter of the central recess 12 in the annulus 2 is about 22 mm in the example shown, so that the center of gravity of this recess 12 is only about 11 mm away from the nearest perimeter 13. Therefore a flying top with annulus 2
1 can be placed on the palm of the hand, in particular on the middle joint of the finger or on the bent knuckle, with complementary centering. Then, with one finger of the other hand, flip one of the open ends 5 of the wing extension 3, which leads the flying top 1 into a high-speed rotational movement.

When the flying top 1 is placed on a flat base for launching and a part of the energy obtained by flipping is introduced into a translational motion, the flying top 1 is hardly braked due to low air resistance. For the reason, fly away at a nearly constant speed. On the contrary, a flying top 1 with a central recess 12
When it is placed on the bent knuckle, the flying top does not fly away while it is playing, but it gains only a high-speed turning motion, and vertically rises like a helicopter.

The twenty-first embodiment of the flying top shown in FIG. 2 is distinguished from the first embodiment in that the central object is not a ring but a disc shape. From this central region 22, three wings 23, which are also installed by shifting 120 ° each, project to the outside. Each of the wings 23 dispersed in a star shape bends from a vertical axis extending substantially radially in a starting point 24 area to an axial direction extending substantially tangentially in a peripheral end portion 25 area.

Here again, the rim 26 is completely rounded,
This ensures that the notches do not adversely affect the stability of the flying top 21. The main direction of rotation 27 likewise extends from the blade tip 25 to an origin 24 located in its front respectively.

As can be seen in the side view of FIG. 5, the wings 23 are again inclined with respect to the base plane 28 of the flying top 21.
This tilt is achieved by a corresponding corrugation in the central region 22, especially at the origin 24. This waveform extends from the corner 29 where the wing 23 is located forward in the direction of rotation 27 thereof to the rear corner 30 while tilting downward. As a result, air molecules are accelerated downward at the time of high-speed turning 27 of the flying top 21.
The 21 gets the lift that produces the best flight characteristics. Contrary to the first embodiment of FIG. 1, the flying top 21 cannot be centered, for example, on a knuckle or the like at the time of starting, so that it always translates in addition to turning motion when it is played. Get exercise.

Although the above-mentioned flying tops 1 and 21 have a rotationally symmetrical bottom surface, the flying top 31 instead holds a basic shape symmetrical to the central axis 32. This is caused by the formation of three different wings 35 to 37 on the disk-shaped central object 34 near the center of gravity 33. The wings 35 and 36 retain a substantially curved shape and are formed in contact with the central object 34 within their perimeters, while the wings 37 are triangular, one side of which is the central region.
Formed in contact with 34. The thickness, diameter and weight of the cross section are almost equivalent to those in Examples 1 and 21.

All wings 35, 36, 37 are surrounded by a rounded perimeter 38. The main direction of rotation 39 of the flying top 31 is clockwise, so that the wings 35 to 37 are inclined downwards in the opposite direction of the turning direction in order to obtain the lift required for long flight. . The wings 35 to 35
The slope of 37 is relatively flat, about 5 ° to 15 °. Vertical launch is not achieved in this embodiment of the flying top 31 either, but the flying top 31 can be flipped at different points 40-42 with respect to the center of gravity 33 by means of wings 35-37 of different shapes. is there.

As a result, the energy generated by a certain starting impulse is separately divided into rotational and translational motions, and low speed ascending flight or high speed flat descending flight due to a low rotational speed and flight which one likes are possible.

Finally, the embodiment of the flying top 51 of FIG. 4 shows a totally asymmetrical shape. A main wing 54 located in front of the central portion 52 of the ring segment having a central angle of about 60 ° in the direction of rotation 53 protrudes almost vertically, and the main wing 54 extends to the main wing by about 30 in the direction of rotation 53.
A very rough feature of this embodiment is that the secondary wing 55 located at the rear is disposed, and the third control or stabilizing blade 56 is located at a position shifted by about 30 °. The area of the secondary wing 55 is the main wing 54
The area of the control blade 57 is about 80-90% of the
~ 20%, relatively small.

In this embodiment, the main wing 54 can be formed for maximum lift, and the control wing 56 is intended to obtain a stable flight condition like a horizontal stabilizer of an airplane.
The wing 55, on the other hand, has been optimized here to play mainly. The main flight speed of the flying top 51 can be adjusted by the length relationship between the main wing 54 and the auxiliary wing 55. It has been demonstrated that optimum long-range flight characteristics can be achieved when the wing length relationship is about 5: 4.
