Description

The invention relates to a fireworks receiving device according to claim 1, and a fireworks body according to claim 7.

For all effects, which are highly effective in the night sky, it is not possible to determine in which direction the stars are ejected. This is left to chance, because spherical and cylindrical fireworks bombs can rotate around all three axes during the ascent and thereby also stagger strongly and rockets can rotate about the longitudinal axis.

When rotating around the longitudinal axis, the term rollers is used.

Since the invention of the fireworks, it has been a great endeavor of pyrotechnicians to make signs, symbols or letters appear in the night sky. So far, this problem has not been solved satisfactorily.

For a long time bullet and cylinder bombs with signs, symbols or letters are known. This effect type is also called figure bombs. If, for example, the firework stars are placed heart-shaped in the burster charge during the production of the effect, then it is quite possible to achieve that the stars are also driven apart in the shape of a heart in the sky. However, the spatial orientation is not determinable, because these fireworks bombs rotate during the climb around all three axes and sometimes very stagger. Due to the friction in the mortar during the launch and the air resistance in the ascent phase, the ball and cylinder bombs are often set in violent rotation. It is up to chance to decide in which spatial orientation the heart shape will emerge. In rare and favorable cases can it may be that the heart is properly represented to the viewer at a particular location. But more often it happens that the heart is upside down, for example, or that all the fireworks stars lie one behind the other and that instead of the broad heart shape, only one line is visible. Typically, many heartbombs must be shot in order to clearly recognize a beautiful heart shape from time to time. This represents a very high effort and the deformed appearing hearts can reduce the experience value of a fireworks display. Generating letters and whole words in the sky is out of the question with this technique.

To alleviate this problem, certain obvious measures have been taken so far to limit the two undesirable degrees of freedom of rotation. In most cases, these are purely aerodynamic measures.

One option is to use fireworks instead of the ball and cylinder bombs. Here one meets for example the so-called ball rockets, which can contain the necessary effect set with the necessary Zerlegerladung. Naturally, the rocket only rotates about its longitudinal axis during the ascent. In the example of the heart-shaped arrangement of the fireworks stars are then generated in each case, for example, vertical hearts, which either coincidentally correct in their full width or much smaller width or only as a vertical line for the spectators, who are located in a certain place see are. Fireworks rockets in the area of large fireworks usually have the disadvantage that a very large safety margin is required. In addition, a very large and powerful rocket motor must be used in order to sufficiently accelerate sufficiently large, mostly spherical rocket heads. The usually high speed of rocket ascension, especially at the end of the shear phase, leads to the undesirable side effect that the effect images are often shown heavily distorted.

Another possibility is to attach to the ball and cylinder bombs ropes, chains and fabric panels, with or without weights and brake bodies, to limit the degrees of freedom. This is sometimes practiced in traditional Maltese fireworks to reduce the unwanted rotation and tumbling, during the trajectory of figure bombs, and to optimize the effect image in such a way that the figures are more likely to stand vertically and thus correctly in the sky. Again, the problem persists that the effect is not always seen in full width. Often it will be compressed for the audience at a certain place only, mirrored and sometimes only to be seen as a vertical line.

Out US 5,339,741 (Disney, Date of the Patent: August 23, 1994, Filing Date: January 7, 1992), it is known that fireworks bombs in the form of a projectile, such as those used in firearms, have better flight characteristics than spherical and cylindrical fireworks, and thus the Precision can be increased. Further described herein is an electronic time fuse with precise time delay for large fireworks effects to increase precision. US2004 / 003744 A1 discloses a firecracker with wings.

Out US 6,324,981 (Lacroix, priority: FR / 98/01261, 23 December 1998 ) is a fireworks known, with which it is possible to obtain figures, letters or any sign in the sky. This is made possible by the prior art by the sign is already deposited in the firecracker in the form with which it is to be written to the sky. In this invention, in particular, the fuel is made of a metal powder such as titanium with a Granule size of greater than 500 microns formed. The advantage of the metal powder is a particularly homogeneous and lasting effect image in the night sky. In addition, aerodynamic measures were taken in this invention: First, instead of the spherical or cylindrical shape a projectile-shaped geometry was selected, as it was already prior art at this time, and by a hollow cylindrical extension with longitudinal slots a kind Umschürzung was added. Both measures are intended to stabilize the trajectory and limit two degrees of freedom. The problem with such a fireworks body is that even here it is not certain that the sign to be displayed in the sky can also be seen in such a way that it is also perceived as such by the spectators of the fireworks. Again, it is left to chance at which angular position the Zerlegerladung ignites and whether the sign is clearly visible. If you want to show a letter like the horizontal "S" shown in the patent, it may well happen that this is rotated by 90 ° and the viewers at a certain place would rather recognize a serpentine line and other letters that are not represent the S, for example, would be shown on the head. If the sign is installed vertically, it can also be perceived as mirrored or with compressed width or only as a vertical line.

The object of the invention is to improve the prior art and in particular to provide a fireworks available that represents a letter, a character, a character or a symbol so in the sky with predeterminable orientation in space that he from the spectators at a certain place as such can always be seen and perceived.

The invention relates to a fireworks receiving device having a shaped body with an upwardly open recess, which preferably has the shape of a hollow hemisphere, and a first open bore at the bottom of the molding, which is centrally located, preferably adjacent to the first bore, a second Is located in the first bore, preferably a through hole or hollow bore, preferably a rod, a so-called guide rod and at least 2 lateral cylindrical hollow holes (2) in the molding or instead of the hollow holes down salaried wings, wherein the shaped body has a sensor for determining the geomagnetic field, wherein the sensor is preferably mounted obliquely to the longitudinal axis.

The first bore preferably has an extension in the form of a hollow cylinder, so that the hollow hemisphere and the likewise hollow cylinder together have quasi a funnel shape. On the outside of the molded body are still preferably at least one, it can also 2, 3, 4, 5 or 6 depending on the size lateral cylindrical hollow holes in the molding attached. These hollow bores are preferably at right angles to the longitudinal axis of the shaped body, but can also in a different internal angle of preferably 85 °, 80 °, 75 °, 70 °, 65 °, 60 °, 55 °, 50 °, 45 °, 40 ° , 35 °, 30 °, 25 °, 20 °, 15 °, 10 ° or 5 ° to the longitudinal axis of the shaped body when it stands on its hollow cylinder and have a closed end, so that rocket motors can be arranged therein After ignition, develop thrust forces and let the fireworks pickup device according to the invention roll around its longitudinal axis because the hollow bores are offset from the central axis.

The molded article is preferably made of cardboard, papier mache, pressed fibers of natural or synthetic origin, wood, Metal or preferably from a plastic such as preferably acrylonitrile-butadiene-styrene, polyethylene, polyester, polyurethanes or any other suitable thermoset or thermoset. Preferably, the shaped body of decomposable plastic or lignin or other decomposable plastics of natural or artificial origin.

Big fireworks effects are used to create a variety of effects in the night sky. Here are mainly so-called ball and cylinder bombs and much less used fireworks rockets.

All of these major fireworks effects usually include so-called stars to produce the desired effect in the night sky. The stars are either rolled according to a very old, traditional method, preferably in mixing drums. In this case, rice grains, small noodles or small metal spheres are preferably placed in a mixing drum together with, for example, a mixture of black powder and, for example, coloring effect sets containing metal salts or other coloring substances.

The stars are therefore preferably beads which have a charge of preferably black powder with an effect set, such as certain metal salts or other coloring substances which produce certain luminous and color effects.

• Rot: Strontiumsalze, Calciumsalze, Lithium
• Gelb: Natriumsalze
• Grün: Bariumsalze, Kupfer, Tellur, Thallium, Zink
• Violett: Cäsium, Kalium
• Weiß, Silberfarben: Magnesium, Aluminium, Titan, Zirconium
• Goldfarben: Eisen, Kohle.

For example, the following colors can be created by using different chemicals as an effect set:

• Red: strontium salts, calcium salts, lithium
• Yellow: sodium salts
• Green: barium salts, copper, tellurium, thallium, zinc
• Violet: cesium, potassium
• White, silver: magnesium, aluminum, titanium, zirconium
• Gold colors: iron, coal.

It is also possible to apply a plurality of different layers to a grain of rice, and thus various effects, such as a color change from red to green to blue, are possible in succession.

In addition to the optical effects and additional acoustic effects are possible, such as preferably rattle, crackling (so-called crackling), whistling and howling.

The mixing drum is moved until the desired star size is reached.

Instead of rolling the stars, they can also preferably be pressed. This more modern process is cheaper and much less time consuming. However, certain effects, such as a color change, can not be generated.

The fireworks stars are preferably used in ball and cylinder bombs as well as rockets, Roman lights, single shots, fire pots and batteries in the area of large fireworks as well as in rockets, Roman lights, single shots, fire pots and batteries in the area of consumer fireworks. The stars preferably show a trail of light after being ignited by the burst of the bursting charge and expelled in a particular direction. For certain types of effects that do not have a burster charge, such as fire pots, the stars are ignited by the ejection charge.

Ball and cylinder bombs are loaded in a mortar and fired. These mortars are preferably made of an open-topped tube with a closed bottom at the bottom. The mortars are preferably vertical or with a certain inclination, with the opening facing up. Usually, several mortars are placed in a mortar rack (mortar rack). The mortar racks are then joined together, for example by struts, so that they stand securely.

A bullet or cylinder bomb preferably has three pyrotechnic charges with explosive: an ejection charge, a bursting charge and an effect set. The firework stars are embedded in the bursting charge as an effect set, which then create the lighting effects in the sky. Due to the explosion of the discharge charge the ball or cylinder bomb is driven out of the mortar. At the same time, one or, for reasons of redundancy, this process often ignites two or more timing fuses or pressed or hammered pre-burners. As the fireworks bomb rises, these timers burn down. The time fuses are dimensioned so that shortly before reaching the culminating point, the bursting charge is ignited. The burster load has two main tasks. First, it ignites the fireworks stars and second, it accelerates the fireworks stars so that they are ejected in different directions. Firework stars, which are more in the center of the explosion, are less accelerated than those in the outer area. Sometimes at the end of the time fuse in the middle of the fireworks bomb is still a booster charge, the so-called Zündsatz. This ensures that the burster charge is ignited evenly in the center.

Rockets are preferably comprised of a disintegrating charge effect set and a rocket motor, and a lead bar. Rockets are put in a launching bracket. The rocket engine is lit and generates the thrust for the ascent of the rocket. At the end of the Ascension phase, the Burst Charge becomes the effect set with the stars ignited. The stars are ignited and, depending on the strength of the bursting charge, accelerated and dispersed in different directions. Typically, one uses the burnout of the rocket motor for the ignition of the Zerlegerladung.

Furthermore Stoppine can be used. It is a kind of igniter that is used in the area of large fireworks. It is distinguished between covered and uncovered Stoppine, wherein a Stoppine is fibrous material impregnated with black powder suspended in water. In a covered Stoppine the fibers are covered with paper or plastic film and therefore burns off very quickly.

Furthermore, it is possible to use electric lighters, which are used in many areas of pyrotechnics in order to ignite pyrotechnic charges. These are not to be confused with the so-called detonators. These are preferably special igniters which additionally contain a booster charge to detonate explosives. An igniter, as used in the field of large fireworks, preferably consists of a small plate of insulating material, on which two electrically conductive tracks are mounted. On one side of the plate preferably the two lead wires, so the ignition cable, soldered or welded. On the other hand, preferably the electrical connection is made with a resistance wire. A small amount of a suitable pyrotechnic set is preferably applied to the resistance wire. The lighter is then preferably provided with one or more layers of protective lacquer and thus sealed and mechanically durable and insensitive to electrostatic discharges. If the lighter with a certain electrical current flows through, so heats the resistance wire and the pyrotechnic charge in the lighter ignites. This creates sparks and heat, which also ignites the ignited pyrotechnic charge outside the lighter. If the electric current through the lighter is sufficiently high, this process happens abruptly and only takes a few milliseconds.

Furthermore, it is possible that instead of the lighter, it is also possible to use bare resistance wire in order to ignite pyrotechnic charges and charges. These lighters operate without a pyrotechnic set, preferably by bringing a piece of wire or, preferably, a resistance wire coil, in close thermal contact with the set or charge or fuse to be ignited during installation. If enough current flows through the wire, it glows and the pyrotechnic material is ignited. It has long been known that, in principle, any light bulb can easily be transformed into an electric lighter by opening the glass bulb and filling a pyrotechnic charge, such as black powder. In the meantime, lighters without a pyrotechnic composition are also commercially available. These include a piece of wire or a filament of single or multiple coiled resistance wire, as used in incandescent lamps. At sufficiently high currents, the ignition process is almost abrupt and takes only a few milliseconds. However, the delay is usually slightly longer than with conventional igniters. The advantage of this variant of lighters is that they are not considered as dangerous goods and may be transported without restriction. Pyrotechnic articles provided with these igniters are not considered to be enriched and may be handled, transported and shipped in containers without any special additional measures.

A fireworks invention preferably has an ejection charge, a bursting charge, an effect set, a guide rod, one or more rocket motors and an electronic unit with a sensor for measuring the earth's magnetic field, a lighter for triggering the ejection charge and a lighter for triggering the bursting charge. Instead of rocket engines, other thrust-producing devices may be used, such as pyrotechnic fountains with or without nozzles, or pressed black powder or other suitable pyrotechnic compositions in a sleeve with or without nozzle or pressurized gases.

The fireworks according to the invention is preferably made of a mortar, ie a tube of preferably 30 cm to 1.5 m, preferably 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm 100 cm 110 cm, 120 cm, 130 cm , 140 cm long shot down. A mortar may preferably be constructed of glass fiber reinforced plastic, cardboard, steel, aluminum, polyethylene or other thermosets or thermosets.

The mortar used preferably has a hole in the bottom through which the guide rod of the novel fireworks body is later inserted.

The guide rod sticks out at the bottom and should not touch the ground.

The mortar is preferably positioned elevated and secured so that the guide bar can protrude downwardly while not touching the ground.

Another solution is preferably to install a bottom of the mortar, with an opening for the guide rod, in the middle of the mortar and to extend down the mortar barrel, as shown in the drawing. The mortar tube can open at the bottom or closed with a floor. If it is equipped with a floor, it can have a closable opening in the floor, so that the lower pipe section can be cleaned.

For these mortars preferably simple frames can be made, similar to those as they are already used in the field of large fireworks.

Alternatively, it is also preferable to construct a holder for a single mortar, preferably, for example, a tripod with standing platforms, which evenly distribute the enormous forces produced during launch to a larger area.

The firework receiving device according to the invention preferably has at the bottom a rod, a so-called guide rod, while this rod can be fastened in the first bore, which can preferably be a hollow bore. This rod may also preferably be attached to the fireworks body and guided through the first bore in the fireworks receiving device. The rod, a so-called guide rod, is preferably a round rod or polygonal rod, preferably a square rod. This has, depending on the size of the fireworks body, a corresponding length, which preferably 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, 40 cm, 45 cm, 50 cm, 55 cm, 60 cm, 65 cm, 70 cm, 75 cm, 80 cm, 85 cm, 90 cm, 95 cm, 100 cm, 105 cm, 110 cm, 115 cm, 120 cm, 125 cm, 130 cm, 135 cm, 140 cm, etc. in 5 cm Steps up to preferably 3 m can be.

This guide rod is preferably made of cardboard, papier mache, pressed fibers of natural or synthetic origin, wood, metal or preferably of a plastic such as preferably acrylonitrile-butadiene-styrene, polyethylene, polyester, Polyurethanes or any other suitable thermoset or thermoset. Preferably, the Leitstab of decomposable plastic or lignin or other decomposable plastics of natural or artificial origin.

A fireworks body according to the invention has a shaped body. In this shaped body, a fireworks body, such as preferably a so-called bomb, attached. A bomb thus has a substantially spherical shape, which is preferred and also a cylindrical or any other geometric shape of the fireworks body is possible. This bomb is similar in structure to the fireworks bombs already used in the area of large fireworks. Typically, these are made from two hollow papal balls. The cardboard balls are filled separately with bursting charge and effect set and then quickly folded. Then the two halves are glued together. For this purpose, for example, first crepe adhesive tape is preferably applied along the gap. Subsequently, a paste-coated paperboard tape is preferably applied to the resulting ball. The ball is preferably multi-layered and overlapped on all sides with a layer of cardboard tape, so that a very stable ball is formed, which is torn when igniting the Zerlegerladung into many small fragments. The cardboard ball should therefore preferably not break up along the gap, but at other locations. The attachment of the bomb is preferably carried out via an adhesive connection, wherein a screw or a fastening by means of bands would be possible. Such a bomb preferably has a cardboard sheath. These bombs preferably have a caliber of 50, 75, 100, 125, 150, 175, 200, 210, 225, 250, 300 or 400 mm, but also any other caliber in the range of about 20 to about 600 mm can be used. The larger the caliber, the larger the achievable effect image in the night sky. The height of rise in m corresponds approximately to the caliber in mm. A caliber of 100 mm gives approximately a rise height of 100 m.

An inventive fireworks body has an ejection charge, which serves to raise the fireworks in height.

This preferably consists of black powder or nitrocellulose powder or other suitable explosives. Advantageous here are explosives such as black powder, which implement relatively slowly and ensure that the firecracker is driven out of the mortar without the firecracker is destroyed. Black powder deflagrates at a speed of 300 to 600 m / s. In the ejection charge, an electric lighter is preferably installed, which is connected to the electronic unit and can be triggered by this. This may preferably be a conventional lighter or just a filament of resistance wire.

As known from conventional fireworks bombs, the black powder is preferably in a small bag or piece of thin tube made, for example, of plastic film. This is preferably installed around the molding and around the guide rod. In order to protect the ejection charge from moisture, water and mechanical stress and to increase safety, this area is preferably wrapped with several layers of paper or plastic film.

The burster charge also preferably comprises black powder or nitrocellulose powder and serves to ignite the effect charge, ie the fireworks stars. The burster charge preferably consists of rice hulls, which with black powder preferably in the ratio 4 parts of black powder to 1 part Rice husk or any other suitable burster charge.

The effect set is embedded in the bursting charge.

In the Zerlegerladung an electric lighter is preferably installed preferably in the center, which is connected to the electronic unit and can be triggered by this. This may preferably be a conventional lighter or just a filament of resistance wire.

In order for the burster charge to ignite quickly and evenly, a primer made from black powder or nitrocellulose powder can preferably be installed around the lighter or around the filament made of resistance wire.

The stars are preferably the fireworks stars described above, which are embedded in the bursting charge as usual. With these stars, characters, such as a heart, letters, characters, symbols or words can be written to the sky.

In order for the fireworks of the invention to function properly, it is necessary to attach a marker to the fireworks bomb so that it can be installed in the correct position. The built-in lighter is a preferably two-core cable out of the ball. On the basis of this cable and by attached to the inside of the ball small magnets can preferably be marked the position of the built-effect set and so the correct assembly can be facilitated. Also, preferably by imaging methods such as X-ray, the internal structure can be made visible after the production of the fireworks bomb to allow the correct installation.

It must be ensured that the stars are not displaced or get confused in any way during launch, which causes high acceleration values.

For example, a holding device for the stars is preferably a styrofoam plate with holes or the stars are rolled up into thin paper or pyro-paper, the aim being that the stars do not get confused on firing and the shape to be displayed is preserved. In the explosion of the burster charge, the holding apparatus should burn, be destroyed, the paper or the Pyropapier shredded and burn quite well, so that the fireworks stars can be freely ejected in the respective direction (Pyropex is nitrated cellulose, which burns very quickly).

Another way to fix the stars is to apply preferably black powder suspension and allow to cure. Also, conventional adhesives and resins can be preferably used for this purpose.

Another possibility is to use a material that is flammable and arranged in the form of a sign that corresponds to the shape of the sign to be received in the sky. This is achieved according to the invention by arranging the sign in the shape of the sign by means of a combustible shaped body, preferably a cardboard, a wax or thermosetting or thermosetting polymer, which corresponds to the shape of the sign to be obtained in the sky. This may preferably be cardboard or preferably foamed plastic, such as Styrofoam, or any other thermoset or thermoset, preferably in the form of a disc, which has depressions or holes in the shape of the character to be obtained in the sky. So with a heart The depressions are heart-shaped, in which the fireworks stars are inserted.

The options listed above can also be combined with each other.

Typical figures and symbols may preferably be heart, double heart, Saturn, cube, butterfly or ring, as well as double and multiple ring, various star-shaped symbols, such as a Mercedes star, smiley face, cat face and umbrella u.v.a.m. be.

Typical letters and characters may be, for example, Latin, Cyrillic, Chinese and Japanese letters or characters.

If several of these effects are built next to each other and ignited simultaneously or with a certain time offset, whole words or sentences can be written in the sky.

Flags and logos can preferably be displayed with different colored fireworks stars. The color is determined by the chemical composition. With red and white stars, for example, a pixel matrix could be shown, which, for example, shows the Swiss flag. The stars can produce any image, as each star acts like a pixel on a screen, the image being initially small and growing ever larger until all the stars have burned out.

The stars can preferably be installed two-dimensionally in one layer or three-dimensionally in the fireworks bomb. For example, the three-dimensional variant lends itself to the symbol "cube", whereby the stars are arranged along the 12 edges of the cube.

If, for example, a letter is to be shown, then this letter can be installed in the later desired orientation in the fireworks bomb. If the audience is far away or if the letter should be recognizable from a great distance, it is advisable to install the letter vertically. At normal distance, an angle of, for example, 45 degrees is suitable. If the audience is very close to the shooting site, the horizontal installation is advantageous.

Both rolled, pressed and cast stars can be used.

To increase the ignitability of the stars, they may preferably be rolled into black powder dust prior to incorporation, or they are preferably provided with a black powder-based coating.

According to the invention, a fireworks receiving device, which has a shaped body with an upwardly open recess, that is preferably in the form of a hollow hemisphere and a first open bore in the bottom of the molding, which is centrally located, preferably with a second bore next to the first bore is smaller diameter, wherein in the first bore a rod, the so-called guide rod may be attached, which bore may also preferably be a hollow bore. If this bore is a continuous one, the baton may also be attached to the fireworks and passed through the first bore in the firecracker receptacle.

The first bore preferably has an extension in the form of a hollow cylinder, so that the hollow hemisphere and the likewise hollow cylinder together have quasi a funnel shape. On the outside of the molding are still preferably at least one, it can also be 2, 3, 4, 5 or 6 depending on the size of lateral cylindrical hollow holes in the molding attached. These hollow bores are preferably at right angles to the longitudinal axis of the shaped body, but may also be in a different internal angle of 85 °, 80 °, 75 °, 70 °, 65 °, 60 °, 55 °, 50 °, 45 °, 40 °, 35 °, 30 °, 25 °, 20 °, 15 °, 10 ° or 5 ° to the longitudinal axis of the shaped body when it stands on its hollow cylinder and have a closed end, so that preferably rocket motors can be arranged therein After ignition, develop thrust forces and let the fireworks pickup device according to the invention roll around its longitudinal axis because the hollow bores are offset from the central axis. Instead of rocket engines, other thrust-producing devices may be used, such as pyrotechnic fountains with or without nozzles, or pressed black powder or other suitable pyrotechnic compositions in a sleeve with or without nozzle or pressurized gases.

This shaped body is preferably made of cardboard, papier-mâché, pressed fibers of natural or synthetic origin, wood, metal or preferably of a plastic such as preferably acrylonitrile-butadiene-styrene, polyethylene, polyester, polyurethanes or any other suitable thermoset or thermoset. Preferably, the shaped body of decomposable plastic or lignin or other decomposable plastics of natural or artificial origin.

An angular momentum arises because the rocket motors are arranged outside the central axis. The direction of rotation is preferably predetermined by the arrangement of the rocket motors and the associated thrust direction. These rocket engines are preferably simultaneously with the ignition of the ejection charge by the hot burned products, the sparks and the enormous pressure as it were by the ejection charge ignited, but they can also be ignited preferably individually and separately from the ejection charge. Preferably, the rocket engines may also have a coating that promotes their ignition.

Preferably, the speed increases during the rise of the fireworks body. At the beginning, the speed is very low because of the inertia. This continues to increase as long as the rocket motors deliver thrust.

In the interior of the molded body is still preferably in the middle of a recess, preferably in hexagonal shape, in which such a shaped device can be placed. Preferably, the device is an electronic module, for example in the form of a printed circuit board.

For the function of the new type of firework, it is important that this electronic unit is installed in a specific orientation to the effect set. For this purpose, for example, markings are preferably present on the board, which indicate how the fireworks bomb must be installed together with the electronics unit. It may also be present preferably a notch in the board and preferably a nose in the molding and a label of the molding so that the correct structure is facilitated or enforced.

This electronic module preferably consists of a printed circuit board with preferably a microcontroller with preferably at least one communication interface, various inputs and outputs, so-called ports, at least one analog input and preferably at least one sensor for determining the earth's magnetic field and all necessary components for the storage of electrical Energy and and preferably a voltage control and an oscillator for Generation of the clock frequency for the microcontroller. Furthermore, this module is able by suitable programming to evaluate the sensor signals and to calculate the correct time of ignition of the bursting charge. The sensor or sensors for determining the earth's magnetic field allows the electronics unit, during the ascent phase, at any time to determine in which position to the earth's magnetic field, the fireworks is currently.

Further, the electronic unit is preferably connected to an external control unit via a cable.

The electronics unit is able to receive the command to launch and initiate the kill itself.

Once the fireworks is shot down, there is no way to provide the electronics unit from the outside with electrical energy. Therefore, capacitors are preferably used, which are preferably charged prior to launch and power the electronics unit during ascent until ignition of the bursting charge.

Preferably, three capacitors are used. The first capacitor should preferably supply the electronics unit and especially the microcontroller with power. The second capacitor is preferably to store the energy required to safely trigger the lighter of the ejection charge. It would also be possible to trigger the ejection charge by means of externally provided energy. But it is advantageous to buffer the energy in a capacitor, because with long cable runs with small conductor cross sections, it can lead to significant voltage drops. The third capacitor is preferably to store the energy required to safely trip the igniter charge lighter.

The electronics unit is preferably programmed prior to launch with various parameters. Preferably, these data are stored non-volatile in the electronics unit, for example in a flash or EEPROM memory, so that they are available unchanged even after an interruption of the power supply. This data can preferably be programmed either already during the production of the electronics unit or at any other time, such as shortly before use.

Preferably, a time window is programmed within which the ignition of the Zerlegerladung should take place. The height is preferably in relation to time, i. It is known after which time each firecracker has reached its minimum height, from which the ignition for the spectators and the environment is safe and the effect is clearly visible. It is also known after which time each firecracker reaches the culmination point. The upper limit of the time window should be chosen so that the culmination point is not reached. The firecracker should be detonated before it starts to fall back to earth. Otherwise, it can not be guaranteed that the sign will be displayed correctly, and in extreme cases, the fireworks would fall back to the earth's surface as a so-called "black bomb".

The time window depends heavily on the caliber used, ie the diameter, of the fireworks body.

• untere Grenze des Zeitfensters für die Zündung der Zerlegerladung, dies entspricht der Mindesthöhe
• obere Grenze des Zeitfensters, für die Zündung der Zerlegerladung, dies entspricht der Maximalhöhe
• Winkel bezüglich zum Beispiel der Nord-Süd-Achse, bei dem die Zerlegerladung gezündet werden soll

The electronics unit in the fireworks is thus essentially programmed with the following parameters:

• lower limit of the time window for the ignition of the Zerlegerladung, this corresponds to the minimum height
• upper limit of the time window, for the ignition of the Zerlegerladung, this corresponds to the maximum height
• Angle with respect to, for example, the north-south axis at which the bursting charge is to be ignited

Further, the time window and roll rate is preferably determined so that the fireworks body preferably makes at least one complete revolution about the longitudinal axis during the time window to achieve any angular position. Preferably, however, the system is tuned so that several revolutions occur within the time window. This ensures that the ignition takes place shortly after reaching the minimum height and that several fireworks of this type, which are ignited simultaneously, are also disassembled approximately simultaneously.

Further, the electronics unit is preferably programmed with the angular displacement with which the character is to be displayed later. After some kind of electronic compass is used here, it is preferable to use the north-south axis as a reference, but theoretically any other reference can be used. If the north-south axis is used and the angular excursion is programmed with 90 °, this means that viewers who are located south of the shooting site can perceive the sign in full width and correctly oriented in the night sky.

The power supply and communication with the control unit can preferably be done via a common cable or two different cables. The common cable can also preferably have only two wires.

When launching the cable connection is preferably interrupted. This can preferably be used to detect the firing. The ignition of the Zerlerger charge is preferably only when the cable break has been detected at the right time.

The capacitor that provides the ignition energy to initiate the ejection charge and the capacitor that provides the ignition energy to initiate the bursting charge preferably can not be charged until the control system is armed and the information is "armed" to the electronics unit in the firework is passed on to increase security. For example, the charge of these firing capacitors may also generally be made shortly before an imminent launch, for example, five seconds before firing, to increase safety as well.

The charging voltage of the capacitors can preferably be measured by means of an analog / digital converter and thus constantly monitored by the microcontroller. The launch is useful only when the charging voltage is high enough to ensure that both the ejection charge and the bursting charge can be safely ignited.

Conversely, these capacitors can be deliberately discharged when the control system is disarmed. The state of charge of the ignition capacitors can preferably be monitored in order to increase safety. This makes it possible to indicate to the user that the ignition capacitors are discharged and that personnel can safely approach the mortar to disconnect the firecracker and discharge it from the mortar.

Over several resistors, which are connected parallel to the different capacitors (main capacitor for the power supply, ignition capacitor for the ejection charge, ignition capacitor for the Zerlegerladung) can be ensured In order to increase safety, the capacitors will discharge automatically within a few minutes if the cable connection is interrupted.

Instead of a discharge resistor, preferably two or more resistors may be connected to ensure safety when a resistor should be defective.

In the electronics unit is preferably a sensor for measuring the earth's magnetic field. In principle, this is an electronic compass. The sensor is installed in relation to the fireworks stars in a predetermined orientation to allow the microcontroller to determine the spatial orientation of the symbol or character to be displayed over the time of ignition of the bursting charge. Furthermore, the sensor is installed in such a way that it mainly measures the component of the geomagnetic field which is horizontal with respect to the earth's surface and thus the relation to the north-south axis can be determined.

In order for the electronics unit to ignite the ejection charge, an igniter is preferably installed in the ejection charge, which is preferably connected to the electronics unit. The ignition cables of this lighter are preferably laid in the second bore with a small diameter in the molding. The bore is preferably sealed by suitable materials, preferably an adhesive, to prevent, at launch, hot combustion products from passing through the bore from the ejection charge into the chamber with the electronics unit and possibly further to the bursting charge.

As soon as the electronic unit receives the order to fire down the control unit, the ejection charge is ignited, but only if all conceivable input conditions are met. These include, for example, the sufficient charge of all capacitors, a functional data connection to the control unit and the useful programming of the fireworks body with the required parameters.

With the ignition of the ejection charge is detected, whether the firecracker has left the mortar. This is preferably done by the detection of the separation of the cable connection at the right time immediately after the ignition of the ejection charge.

If it has been recognized that the launching has not taken place, the process is preferably stopped in order to avoid a pipe rupture. In such a case, the capacitors are deliberately discharged relatively quickly to establish a safe operating condition for removing the firecracker from the mortar.

With the successful launch, a time counter is preferably started in the electronics unit. This is used to control the timing, taking into account the programmed parameters.

Upon successful launching, it is also preferable to start acquiring the measured values of the geomagnetic field sensor in order to continuously determine the rate of rotation and the angular position of the longitudinal axis of the firework with respect to, for example, the north-south axis.

Once the ejection charge is ignited, the fireworks rises and is offset by the rocket motors in a rotation about the longitudinal axis with a predetermined direction of rotation. Because of the inertia, the speed increases during the ascent, while the rocket motors constantly provide a relatively even thrust.

By continuous measurement of the signal of the geomagnetic field sensor preferably the software (firmware) of the electronics always calculates the instantaneous rotational speed, ie the angular velocity. From this, the spatial orientation can be derived at any time.

During the ascent, the sensor preferably provides an approximately sinusoidal signal whose maxima and minima indicate north-south orientation and south-north orientation. The frequency corresponds to the speed.

The time between two minima or maxima is one period and this time is exactly one revolution. Half of this time equals one half turn. A quarter of this time is equivalent to a quarter turn, etc.

With this method, the current angular velocity and angular position can be calculated at any time.

During this ascent phase, ie in the time between the launch and the reaching of the lower limit of the time window, the electronic unit preferably evaluates the signals of the earth magnetic field sensor and thereby determines the current rotation rate and thus also the actual angular velocity of the fireworks body.

As soon as the lower limit of the time window has been reached, the optimum ignition point can be calculated from the current angular velocity.

Especially at higher rotation rates, even small time delays can have a negative effect on the correct display of the sign in the night sky. A time delay is mainly caused by the fact that the lighters cause a certain delay of a few milliseconds. For this reason, the ignition timing should be moved slightly forward, depending on the ignition delay, by including a correction factor depending on the current yaw rate.

Once the optimum ignition point has been reached, preferably the bursting charge is ignited. For this purpose, a lighter is preferably in the middle of the Zerlegerladung. This lighter is preferably connected via a cable to the electronics unit. This cable may be laid in a variety of ways, such as preferably in a sleeve within the fireworks bomb, and preferably in a bore within the molding. To increase safety, preferably the sleeve and the second bore should be sealed with a suitable material, such as preferably an adhesive, so that there is no danger of premature ignition. However, the cable can also preferably be routed outside on the fireworks bomb and guided at any point into the bursting charge.

In order to promote the ignition of the bursting charge and, to ensure uniform ignition, the bursting charge may preferably be provided with an additional priming charge, such as black powder dust or granules.

The character or letter now appears in the correct orientation in space, so that viewers can see and recognize it well and correctly at a certain location.

Fragments of the shell of the fireworks bomb fall to the ground. Likewise, the Leitstab and the molding.

Should the electronics unit not be able to calculate a suitable ignition point during the flight phase, for example if the earth magnetic field sensor fails to supply a signal due to a defect, ignition of the disintegrating charge preferably takes place upon reaching the upper limit of the time window, to prevent a so-called "black bomb".

The following meaningful embodiments of the invention are conceivable and the following developments are offered:
Instead of conventional igniters containing pyrotechnic material, it is also preferable to allow all-electric ignition by igniting by the heat generated by the voltage applied to a filament. The filament preferably consists of a piece of wire or preferably has single or multiple filaments which rapidly glow and ignite the respective charge, ie either the ejection charge or the bursting charge. If the firecracker is equipped with these glow starters, it is not considered bezundert and may be transported in traffic or at sea. Typically, these lighters have a slightly longer ignition delay, which can be taken into account in the calculation of the ignition timing.

In order to increase the amplitude of the output signal of the magnetic field sensor, the active surface of the sensor can preferably be mounted obliquely to the longitudinal axis of the fireworks body and thus adapted to the local prevailing inclination angle of the earth's magnetic field.

In order to detect whirling movements or other abnormalities in the trajectory of the fireworks body, preferably a second magnetic field sensor can be installed, whose active area is aligned horizontally to the longitudinal axis of the fireworks body, so that the perpendicular to the earth's surface magnetic field component is also detected.

The methodology for the safe detection of firing can be supplemented by the following measures:
For reliable detection of the firing, the signal of the magnetic field sensor can preferably additionally be used, and it can be examined whether the rotational speed, ie the frequency, increases with time. It can also be examined whether the sensor delivers a sinusoidal signal.

For reliable detection of the launch, the signal of a thermistor can preferably also be used, which is attached to the underside of the molded body. It can be examined whether the temperature has risen suddenly by the ignition of the ejection charge.

For reliable detection of firing, in addition, the signals of preferably up to three acceleration sensors for up to three axes and the signals of up to three gyroscopes for up to three axes can be used, which are integrated in the electronics unit.

Instead of a plurality of capacitors, it is also possible to use preferably a central capacitor which supplies the energy for operating the electronic unit and the energy for igniting the ejection charge and the bursting charge.

Instead of standard electrolytic or tantalum capacitors, it is also possible to use capacitors with an extremely high capacitance, so-called double-layer capacitors.

To store the electrical energy and to operate the electronics unit and to trigger the lighter can be used instead of capacitors also preferably batteries or rechargeable batteries, ie primary or secondary elements.

Instead of a microcontroller, a microprocessor can preferably also be used. In this case, other components within the electronics unit are preferably required: RAM, ROM, EEPROM, port devices and A / D converter.

The electronics unit may also preferably be mounted under a protective cover at the top of the firework or at another suitable location.

The communication between the external control unit and the electronics unit may instead function by means of a cable in a variety of ways: by radio, by inductive or capacitive coupling, by ultrasound or by optical coupling by means of visible or invisible light of any wavelength in free space or by light guide , The compound may preferably be with or without data exchange. The data exchange may preferably be unidirectional or preferably bidirectional. The connection to the control unit may preferably be with or without power or power supply to the electronics unit in the fireworks body.

Instead of a single fireworks body, preferably several of these fireworks may preferably be operated on a common communication means such as a cable. This network can have different topologies. These include essentially preferably the network topologies line, bus, star, tree or ring, as well as meshed and fully meshed.

If several fireworks are operated within the framework of a network, it can be ensured, preferably by suitably attached strain reliefs, that the remaining network remains intact and operable in the event of a firing with separation of the connection to the network.

Instead of a Leitstabs also preferably a projectile-shaped fireworks bomb similar to the shape of a projectile of a firearm with a tail or otherwise suitable geometric shape is possible, the tail preferably influences and dictates the direction of rotation and speed.

The fireworks body could preferably be cylindrical or projectile-shaped and have turned grooves on the outside, so that upon firing from the mortar, a twist with a certain twisting direction with a certain twisting speed is created. The speed curve changes as a result. At the beginning of the flight phase, this is high and over time it decreases continuously.

The fireworks could preferably be cylindrical or projectile-shaped, and the mortar could preferably have traction, such as helical grooves, to set the firework in rotation and to impart a spin to the firework, just as a gun-run is used to pull the firework Projectile to give a twist. The speed curve changes as a result. At the beginning of the flight phase, this is high and over time it decreases continuously.

The fireworks could preferably be cylindrical or projectile-shaped and the mortar could also have a twisted polygon structure similar to a helix to impart a certain twist to the fireworks, as well as in firearms, a polygon run is used to impart a spin to the projectile. The speed curve changes as a result. At the beginning of the flight phase, this is high and over time it decreases continuously.

A further subject matter is a method for firing a fireworks body according to the invention wherein the fireworks are placed in a mortar for firing, which is raised and fixed so that the firebrig's conducting bar can protrude downwardly and not touch the ground.

Preferably firecracker according to the invention is introduced for launching in a mortar having a bottom, with an opening for the Leitstab in the middle of the mortar and the mortar tube is to extend down, the mortar tube may be open at the bottom or closed with a bottom, where, when equipped with a floor, it may have a closable opening in the floor so that the lower pipe section can be cleaned.

Preferably, the fireworks of the present invention are placed in a mortar for launch having features, such as preferably helical grooves, or the mortar has a polygon structure to set the fireworks in rotation.

The guide rod may preferably have a foldable tail at the end, wherein the tail influences the direction of rotation and rate of rotation.

A tail could also be located preferably at the top, so the top of the fireworks body.

Instead of a discharge charge of pyrotechnic material, the fireworks could also preferably be driven out of the mortar by means of compressed air or other pressurized gases. If gases are used, they can also be in liquefied form. By opening a valve, the vapor pressure of the gases can be used to drive the firecracker out of the mortar.

To increase safety and reliability, there are several ways to achieve redundancy.

In addition to the electronics unit, one or more pyrotechnic time delays, preferably fuses, could preferably be incorporated, which are preferably ignited by the ejection charge and whose delay is such that the bursting charge is ignited at approximately the culmination point should the electronics unit fail.

The firing capacitors and the output transistors could preferably be present in duplicate, so that the ignition still takes place, in the event that a circuit part should fail.

There could preferably be two or more magnetic field sensors so that the fireworks can still function properly should a sensor be defective.

In addition to the electronics unit, there could preferably be a further stand-alone electronics unit which provides an electronic ignition delay with a preset time. If the main unit failed, the second electronics unit would fire the burst charge approximately when the culmination point is reached. The ignition signals of both units could be fed by diodes to a common lighter in the bursting charge. In addition to the electronics unit, there could preferably be another independent electronics unit which operates identically and has two independent lighters. If the electronics unit failed first, the second electronics unit would fire the bursting charge at the right time.

The data transmission between the control unit and the electronic unit in the fireworks can be made particularly safe by the use of protocols with checksums with cyclic redundancy check (CRC) and encryption such as AES.

If it is advantageous, preferably also a piece of Stoppine can be installed between the igniters and the respective charges. The additional delay time through the Stoppine can be taken into account in the calculation of the ignition timing of the Zerlegerladung.

The baffle and plastic moldings could preferably contain explosive in cavities which, for example, are ignited together with the rupturable charge and destroy these parts, so that only small fragments fall to the ground, which pose no danger.

Another alternative is that the guide bar and the plastic molding are preferably equipped with a parachute which is ejected, so that these parts slide slowly and safely to the ground after ignition of the burster charge.

It is possible to use both preferably rolled and pressed fireworks stars. The latter are usually cylindrical.

Instead of the stars, it is preferable to use metal powder or granules of any grain size and other color powders or granules of any grain size and carbon in all available forms, which oxidizes in the air and causes a luminous appearance, thereby producing a more homogeneous effect image can. The powders and granules may be pressed or loose.

To increase the effect, preferably one or more fireworks stars can be mounted outside in the upper area of the fireworks body. These are ignited when fired by the hot products of combustion and cause a spark tail during ascent. This effect is known in the large fireworks area as a so-called palm. The tail forms the palm trunk. Firework stars draw the palm leaves to the night sky.

The pyrotechnic set in the rocket motors can preferably be additionally provided with effect sets to increase the effect. These can serve the optical and acoustic effect increase.

The following alternative solutions are conceivable.

If the rocket motors are preferably oriented slightly downwards to provide thrust up, it may create an effect similar to a firework rocket, with the thrust of the rocket motors causing the fireworks to rise. So could preferably be dispensed with a mortar and on the ejection charge.

An alternative, instead of the hollow holes and the rocket motors or in addition to the hollow holes and the Rocket motors, preferably attached down-mounted wings to the molding. These wings may be mounted in a number of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, and during the ascent phase also cause the fireworks to roll in a predetermined direction of rotation about the longitudinal axis.

Preferably, one to three acceleration sensors for up to three axes and one to three gyroscopes for up to three axes can be present and evaluated in order to compare the typical acceleration values with the actual ones and to verify the successful launch and the correct ascent. This sensor system can preferably additionally be evaluated during the entire trajectory in order to increase safety and precision. By means of this so-called inertial navigation, however, under certain circumstances it is also possible to dispense entirely with magnetic field sensors, guide rods, moldings and rocket motors. The electronics unit would then sit within, for example, a preferably ball-shaped or cylindrical fireworks bomb and the fireworks bomb would rotate in all degrees of freedom and be fired at the appropriate time.

Preferably, the shaped body can determine its position in three-dimensional space by evaluating radio signals from communication or navigation satellites. By evaluating the radio signals of communication or navigation satellites could preferably be dispensed inertial navigation, magnetic field sensor, guide rod, moldings and rocket engines. The electronics unit would then sit within a, for example, spherical or cylindrical fireworks bomb and the fireworks bomb would rotate in all degrees of freedom and be fired at the appropriate time.

If the electronics unit is not intended to trigger the launch itself, ignition of the ejection charge may also be conventionally done by means of a built-in lighter connected to an ignition system or by hand by means of a fuse such as Stoppine. In this case, the electronics unit must preferably detect the firing, for example by means of temperature and acceleration sensors or with the magnetic field sensor.

In the simplest case, the electronic unit is preferably informed by applying a voltage to two lines that the launch should be initiated. In this simplest case, the control unit is preferably a simple voltage source such as a battery or a rechargeable battery or any existing ignition system for the pyrotechnics. Also with this, the capacitors can be charged as described and after a certain time, when this process is completed with certainty, for example after five seconds, the ejection charge can be ignited by the electronics unit and the entire process up to the ignition of the Zerlegerladung to be started.

The functional principle described here can also be applied to other types of fireworks. These include preferably parachute bombs, Girandolas, so rising crowns, and rockets.

The invention surprisingly allows a large firework effect with electronics unit for generating two- or three-dimensional figures, letters, characters, numbers, numbers, flags, logos and symbols in the sky, the time of the decomposition and thus the effect height and the location and Orientation in the room are determinable to provide.
