Description

The present invention relates to a firework according to the preamble of claim 1, with at least a first receiving part for a pyrotechnic effect, and at least one ignition means connected to the pyrotechnic effect. In addition, the present invention relates to a firework battery with at least one firework according to the preamble of claim 12 and to a method for lighting at least one second firework by a first firework according to the preamble of claim 13.

Fireworks are known from the general prior art which ignite a pyrotechnic effect arranged in a firework by means of an ignition means. The ignition means is usually an ignition cord which is guided by the pyrotechnic effect to the outside of the firework so that it can be ignited by a user. In addition there are firework batteries known, which have a plurality of fireworks, which are pyrotechnically connected to each other with an ignition means. In the event that a plurality of fireworks and / or firework batteries are connected or connected in series or in parallel, it is necessary in the general prior art to ignite the fireworks or firework batteries by an ignition means, which is usually designed as an ignition cord, interconnect pyrotechnically. This is the only way to ensure that several fireworks or firework batteries can be lit simultaneously or in parallel. From the DE 11 2004 001 284 B4 a firework is known which has at least a first receiving part for a pyrotechnic effect and has at least one ignition means connected to the pyrotechnic effect. On the firework, the ignition energy introduced by the ignition means is conducted through a connecting channel into a second firework that is in contact with and connected to the first firework, so that a second pyrotechnic effect can be ignited.

However, the solutions from the prior art have the disadvantage that the fireworks or the firework batteries must be pyrotechnically connected to one another by means of an ignition means, which is usually designed as an ignition cord, and accordingly are always connected on the material side and are in contact via this ignition means. The ignition device that connects the fireworks or firework batteries forms a great potential for failure or interruption potential. It is not uncommon for environmental factors to play a major role here, as the function of the ignition device is impaired. Moisture, in particular, is a major problem here because it is very likely that a pyrotechnic connection will be prevented, so that ignition of a pyrotechnic effect is prevented. In addition, a connection of several fireworks or firework batteries via an ignition means limits the possibilities of the geometrical arrangement of the fireworks or firework batteries to one another as far as possible. This applies particularly to over-the-counter fireworks or firework batteries, which usually have a conventional fuse.

From the publication DE 299 06 172 U1 A firework battery is known in which several firecrackers are mechanically connected to one another in such a way that the firing devices of all firecrackers are located adjacent to one another in a common firing chamber and can be ignited there due to the geometric arrangement.

It is therefore the object of the present invention to at least one of the disadvantages described above in a firework or a firework battery at least partially fix it. In particular, it is the object of the present invention to create a firework, a firework battery and a method for lighting, while at the same time fireworks or firework batteries, which are arranged at a distance from one another, are ignited in a simple and inexpensive manner without using a material ignition means to be connected.

The above object is achieved by a firework, a firework battery and a method for lighting a firework battery with the features of claims 1, 12 and 13. Further features and details of the invention emerge from the subclaims, the description and the drawings. Features and details that are described in connection with the fireworks according to the invention also apply, of course, also in connection with the firework battery according to the invention and the method according to the invention and vice versa, so that with respect to the disclosure of the individual aspects of the invention, reference can always be made to one another.

The firework according to the invention has at least a first receiving part for a pyrotechnic effect and at least one ignition means connected to the pyrotechnic effect. It is essential to the invention that at least one auxiliary ignition system is provided which can be ignited by the ignition means, an ignition flame being able to be generated by the auxiliary ignition system, and the ignition flame being able to be led out essentially horizontally from the firework, whereby at least one additional firework with a pyrotechnic effect can be ignited ,

The receiving part is to be understood here as a geometric body in or on which at least one pyrotechnic effect can be arranged. A pyrotechnic effect is a mixture of substances for producing acoustic, optical, thermal or mechanical effects, whereby the mixture consists of explosive substances that are subject to the corresponding legal regulations, which means that increased safety regulations apply. An ignition means in the sense of the invention is to be understood to mean all ignition or auxiliary ignition means which serve to trigger or ignite a pyrotechnic effect. You provide the necessary initial energy for the chemical reactions from the pyrotechnic mixtures available. In particular, ignition means are to be understood to mean typical ignition means for manual ignition, an incomplete list of exemplary ignition means being given below. Detonating cords are among the most common detonators which transfer the ignition to the pyrotechnic effect and can also be designed as retarders and which delay times of a few seconds, e.g. B. by means of slow-burning fuses (timing fuse, ignition wire, China fuse, sump fuse). Ignition lights are also conceivable, in which a special magnesium set is used, which is also insensitive to moisture. Ignition cord usually consist of a sleeve with a friction head, which z. B. is rubbed against a friction surface of a matchbox and thereby provides the necessary initial energy for the chemical reaction. Within the scope of the invention, ignition tags are also conceivable, which consist of an easily flammable material and accordingly pass on the ignition energy, which is introduced by a match or a lighter, to the pyrotechnic effect. In addition, it can also be a membrane which is designed such that an introduced thermal energy is passed on via the membrane to the pyrotechnic effect, so that the required initial energy can be made available accordingly. An essential core of the invention is the auxiliary ignition system according to the invention, which can be ignited by the ignition means, whereby an ignition flame can be generated by a pyrotechnic effect and / or pyrotechnic object arranged in the auxiliary ignition system. Accordingly, the auxiliary ignition system consists, among other things, of a mixture of substances for producing at least thermal effects, so that an initial energy in the form of thermal energy can be transmitted via it. This thermal energy is generated in the form of a pilot flame by the auxiliary ignition system, the pilot flame in particular being able to be led out essentially horizontally from the firework, so that the thermal energy which is required as initial energy for lighting an additional firework with a pyrotechnic effect can be transferred. An ignition flame in the sense of the invention accordingly replaces a material connection, for. B. in the form of a fuse, which is necessary to pyrotechnically connect at least two fireworks and / or firework batteries. Consequently, the pilot flame transfers at least so much thermal energy that it is sufficient, the initial energy to provide another pyrotechnic effect. The pilot flame has a direction of effect which is guided essentially horizontally away from the firework, whereby horizontally from the firework is to be understood as a horizontal spread in the case of a vertical or upright firework. In particular, it should be understood that the fireworks release the essential, ie largest, portion of the pyrotechnic effect in the vertical or vertical direction. As a rule, the vertical direction is the contact surface or the surface (floor) on which the firework is arranged or the opposite direction (sky). The auxiliary ignition system according to the invention can be arranged at any point on the firework, whereby this implies that the auxiliary ignition system can be partially or completely integrated into the firework and / or the first receiving part or can also be attached outside the firework. Within the scope of the invention, it is also conceivable that a plurality of auxiliary ignition systems are provided, these being able to be arranged at different locations on the firework and generating an ignition flame in different directions. Accordingly, additional, ie external, fireworks with a pyrotechnic effect can be lit by the lack of a pilot flame, the fireworks being in each case spaced apart and possibly arranged in contactless fashion with one another.

According to the auxiliary ignition system is arranged in a second receiving part. In particular, an insulation element is at least partially arranged between the auxiliary ignition system and the pyrotechnic effect. The second receiving part is also to be understood here as a geometric body, in or on which at least one chemical substance mixture can be arranged to produce thermal effects or energy. The second receiving part can, for. B. be can-shaped, cylindrical, cuboid, pyramid-shaped or have similar volumes. The first receiving part and / or the second receiving part can have a cellulose, a plastic, wood or metal. The use of cellulose is particularly environmentally friendly because it enables production with renewable raw materials, which also results in low material costs. The use of a plastic offers the advantage of a long durability as well as a high resistance to environmental influences as well as the force caused by transport or improper use Treatment. Similar properties also result when using a metal, with an additional ecological advantage being achievable through material recycling. In addition, the first and / or the second receiving part can also have gypsum, clay, quartz or ceramic, since these materials have good thermal resistance. According to the invention, it is conceivable that an insulation element is at least partially arranged between the auxiliary ignition system and the pyrotechnic effect. This insulation element can, for. B. in the form of a refractory bottom of the second receiving part. The insulation element according to the invention at least partially prevents or at least partially reduces or reduces the transition from thermal energy from the auxiliary ignition system to the pyrotechnic effect. In addition, the kinematic energy generated by the ignited auxiliary ignition system is directed in a certain direction, which is preferably the direction out of the firework. This ensures that the initial energy required to ignite another firework with a pyrotechnic effect can be transmitted in the desired direction. The insulation element can partially or completely encompass the second receiving part, the ignition means advantageously projecting through the insulating element and / or the second receiving part at at least one point. It is also conceivable that a breakthrough, ie a material recess along the insulation element and / or the second receiving part, serves as an ignition means if a chemical substance or material is present in this area which is used to transmit the initial energy for igniting the auxiliary ignition system or pyrotechnic effect is formed.

It is also advantageous if a casing is arranged on the fireworks or the first receiving part. The casing can be a label on which instructions for use, danger or other information are shown. This can e.g. B. in the form of a band around the firework or around the receiving part. The casing can e.g. B. by an adhesive connection, a Velcro connection or a screw connection to the firework and / or to the receiving part of the first receiving part and preferably have a cellulose, a plastic, wood or metal. The use of cellulose is particularly environmentally friendly because it enables production with renewable raw materials, which also results in low material costs. The use of a Plastic offers the advantage of a long shelf life as well as a high resistance to environmental influences and the effects of force caused by transport or improper handling. Similar properties also result when using a metal, with an additional ecological advantage being achievable through material recycling.

Furthermore, it is conceivable that the ignition means protrudes at least partially from the first receiving part of the pyrotechnic effect and / or from the casing of the firework and / or from the second receiving part from the auxiliary ignition system. If the ignition means protrudes at least partially from the first receiving part of the pyrotechnic effect and / or from the casing of the firework, this corresponds to an ignition means which is accessible from the outside and which the user applies an initial energy to, which leads it to the pyrotechnic effect via the ignition means , This can be, for example, an ignition cord that is ignited by a user from the outside, so that the thermal energy is conducted to the pyrotechnic effect via the ignition cord. The ignition means can, if it only protrudes from the first receiving part, thus z. B. are still behind the casing, so that it at least partially protects the ignition means through the casing against environmental influences. The same applies to the arrangement of the ignition means on or in the second receiving part of the auxiliary ignition system, so that the initial energy can be introduced by the user from the outside. Accordingly, by introducing the initial energy for ignition, both the pyrotechnic effect and the auxiliary ignition system can be ignited if the ignition means protrudes from the first receiving part of the pyrotechnic effect and / or from the casing of the firework and / or from the second receiving part of the auxiliary ignition system.

According to the invention, the pyrotechnic effect and the auxiliary ignition system can be pyrotechnically connected by the ignition means. For this it is necessary that the ignition means is arranged at least in sections in the pyrotechnic effect or in the first receiving part and at least in sections in the auxiliary ignition system or the second receiving part of the auxiliary ignition system. Due to the pyrotechnic connection, with the introduction of the initial energy for ignition at only one point or at only one end of the ignition means, the pyrotechnic effect and the auxiliary ignition system can be lit. The pyrotechnic connection can in this case be connected by a fuse and / or a pyrotechnic separating layer, an ignition paper, an ignition plate or a suitable ignition means as described above.

Furthermore, it is conceivable that at least one positioning aid and / or a support aid is arranged on the first receiving part and / or on the casing. It is particularly conceivable that the positioning aid and / or the support aid is formed from part of the casing. The positioning aid serves to position the firework or the receiving part in such a way that the auxiliary ignition system is arranged in a suitable position for igniting an opposite firework, so that the pilot flame can transmit enough initial energy that a further pyrotechnic effect can be ignited. A support aid in the sense of the invention serves to increase the stability of the firework, particularly when the auxiliary ignition system is ignited and energy is generated by the ignition of the explosive chemical mixture, which can possibly move the firework away from its original position. This increases stability on the one hand, which means that the pyrotechnic effect and / or the auxiliary ignition system are not moved into an unwanted position in which the pyrotechnic effect and / or the auxiliary ignition system can cause damage to surrounding objects and / or people. According to the invention, it can be advantageous for the positioning aid and / or the support aid to be formed by a section of the sheathing, so that the positioning aid and / or the support aid are formed in one piece or in the same material. In addition, the positioning aid and / or the support aid can have additional reinforcement elements which are arranged in the form of reinforcement struts or inserts, in particular made of a plastic or a metallic material, on and / or in the positioning aid and / or the support aid.

In the context of the invention, the positioning aid and / or the support aid can have at least one connecting means, whereby an at least mechanical connection can be established with at least one connecting means arranged on an additional firework. A connecting means according to the invention can, for. B. be formed as a material recess or a corresponding shape, which enables at least two connecting means to form and / or can be non-positively connected. For this purpose, a complementary geometry of the connecting means can be provided or the connecting means z. B. be formed as a slot in the positioning aid or the support aid, so that two connecting means can be nested or plugged together. Furthermore, it is conceivable for the connecting means to be designed as a hook or an eyelet and for two corresponding connecting means to be connected in each case. Adhesive and / or Velcro connections are also conceivable, as a result of which an at least non-positive and / or positive connection can be established. In particular, it is conceivable that the adhesive and / or Velcro connection is protected before use with a protection, for example a protective film, against external influences (for example dirt, moisture) and unintentional sticking together. A connecting element according to the invention enables a connection of at least fireworks in all the exemplary embodiments, so that the stability of the individual fireworks is increased and at the same time the fireworks can be positioned relative to one another. B. the pyrotechnic effects in their direction of action / arrangement (circular or at a special angle to each other) can be influenced. The spacing of the fireworks from one another can also be determined, so that, as a result of the pyrotechnic effects, displacement of the fireworks is at least substantially prevented.

According to the invention, it is conceivable that the positioning aid and / or the support aid is arranged movably on the receiving part. The positioning aid and / or the supporting aid can be arranged in a particularly advantageous manner on the receiving part and / or on the casing. For this purpose it can be provided that the positioning aid and / or the support aid have a hinge so that they can be freely positioned. Foldable in the sense of the invention is to be understood as a positioning aid and / or support aid that can be moved in the horizontal direction and / or in the vertical direction. This makes it possible that, on the one hand, the stability can be improved in such a way that mechanical forces are transmitted from the firework to a stand area, the position of the positioning aid and / or support aid being adaptable to the stand area in particular by means of a folding mechanism and, on the other hand, an existing one Lanyards can be variably positioned with a lanyard present on another firework.

The positioning aid and / or support aid according to the invention can primarily be able to be brought at least into a closed position and into an open position, the positioning aid and / or the support aid being arranged essentially flush on the receiving part in the closed position and a connection with at least one on the one in the open position additional fireworks arranged positioning aid and / or support aid can be produced. Accordingly, the fireworks have a small pack size in the closed position and the positioning aid and / or support aid can only be brought into the open position if necessary.

It is also advantageous that the auxiliary ignition system can be arranged on or in the casing and / or on or in the first receiving part. According to the invention, it is conceivable that the auxiliary ignition system or the second receiving part is arranged in the first receiving part, where the pyrotechnic effect is also accommodated. The auxiliary ignition system can also be in contact with the casing or at least partially have a positive and / or non-positive connection. For this purpose, the auxiliary ignition system can be connected to the first receiving part and / or to the casing via an adhesive, plug-in, snap-in or screw connection.

According to the invention, the insulation element can have cellulose and / or gypsum and / or clay and / or quartz and / or metal and / or ceramic. In particular, when using cellulose, this can be coated in order to further improve the material properties and in particular to increase the thermal resistance of the cellulose. Gypsum, clay, quartz, metal or ceramic have a high thermal resistance, so that the auxiliary ignition system can be thermally and pyrotechnically separated from the pyrotechnic effect. This can, for. B. can be achieved that a delayed ignition of the auxiliary ignition system or the pyrotechnic effect can be produced by targeted insulation with an insulation element.

According to the invention, a safety element can be arranged on the auxiliary ignition system, as a result of which the pilot flame can be prevented from escaping. Preventing the emergence of the pilot flame from the auxiliary ignition system or the fireworks can be advantageous if the fireworks are to be used alone, without further external ones Ignite firecrackers. Accordingly, the security element can, similarly to the insulation element, have a cellulose and / or plaster and / or clay and / or quartz and / or metal and / or ceramic, so that this results in a high thermal resistance. The security element in this case preferably has at least the same geometric size that the pilot flame of the auxiliary ignition system can reach to the maximum. The security element can be designed to be reversible and / or lockable and / or screwable and / or glued. In addition, it can have predetermined breaking points or only be glued at points so that it can be attached or detached as required. The security element can also be in the form of a security label, e.g. B. in the form of the casing. Here, the casing can have predetermined breaking points or a perforation at the point at which the auxiliary ignition system is arranged, so that it can be removed from the casing if necessary. This ensures that an unintentionally escaping pilot flame from the auxiliary ignition system or the firework is prevented, so that damage to external objects or people is prevented. An inadvertent ignition of the auxiliary ignition system by a security element is at least partially prevented, or the resultant effect is largely prevented.

In the context of the invention, it is conceivable that a safety mechanism for the auxiliary ignition system is arranged, as a result of which, in particular, the ignition means can be pyrotechnically separated or connected. A safety mechanism according to the invention serves to interrupt the ignition means, so that the initial energy can be interrupted to ignite the pyrotechnic effect and / or the auxiliary ignition system. This also prevents accidental ignition of the pyrotechnic effect and / or the auxiliary ignition system, which further increases safety. This can be, for. B. can be a mechanical device and / or a material property that enables the ignition means and / / the auxiliary ignition system to be pyrotechnically separated or connected. This can e.g. B. by separating the ignition means or by introducing additional material between the ignition means and the auxiliary ignition system or the pyrotechnic effect. Is z. For example, if the ignition device is led outwards using the safety mechanism or removed from the auxiliary ignition system, there is no longer a pyrotechnic connection between the ignition device and the auxiliary ignition system. Consequently, the initial energy required to ignite the auxiliary ignition system are no longer transmitted, so that the pilot flame does not escape from the auxiliary ignition system. It is also conceivable that the ignition mechanism can only be introduced into the auxiliary ignition system by the safety mechanism, so that initial energy can only be introduced via the auxiliary ignition system by actuating the safety mechanism.

Furthermore, it is conceivable that the pilot flame has a radiation angle α to the horizontal in a range between 90 ° and 0 °, advantageously between 44 ° and 20 °, preferably between 19 ° and 0 °. The radiation angle α geometrically indicates the area that is present between the horizontal axis of symmetry of the auxiliary ignition system and the casing or the firework. Accordingly, the radiation angle α between the horizontal and the casing of the firework can have a range between 0 and 90 °, 0 ° forming the horizontal or the horizontal axis of symmetry of the auxiliary ignition system. In order that as large a part of the initial energy as possible of the initial energy generated by the auxiliary ignition charge and thus a large part of the pilot flame reach the second, spaced, external firework, the radiation angle α advantageously has a range between 44 ° and 20 °. It is particularly preferred if the pilot flame has a radiation angle α in the range between 19 ° and 0 °, since in this region as large as possible a portion of the pilot flame and thus the initial energy required to ignite a further firecracker leads out in the desired direction.

According to the invention, the pilot flame can have an outlet length in the range of 2 mm and 300 mm, advantageously between 5 mm and 150 mm, preferably between 10 mm and 50 mm. The exit length determines the possible geometric arrangement of the two opposing fireworks, so that enough initial energy can be transferred by the pilot flame from one firework or from the first auxiliary ignition system to the second firework.

It is also advantageous if the pilot flame has a burning time in the range between 25 seconds and 60 seconds, advantageously between 29 seconds and 45 seconds, preferably between 1 second and 15 seconds. A shorter burning time increases security against outsiders or objects not involved, so that damage to these can be largely reduced. The longer burning time, on the other hand, enables a higher probability of igniting another firework, especially if the transmission conditions for the transmission of the initial energy by the pilot flame are impaired by environmental influences.

Furthermore, it is conceivable that the pilot flame can be achieved by a pyrotechnic signal ignition means and / or a Bengali fire and / or a shellac fire and / or a flame surface and / or a pyrotechnic effect and / or a pyrofluid. The use of a pyrotechnic signal igniter and / or a Bengali fire and / or a shellac fire and / or a pyrotechnic effect makes it possible to achieve additional pyrotechnic effects which at the same time serve to transmit the initial energy through the pilot flame to another firework. The use of a flame surface or a pyrofluid can have advantages in terms of installation space, since these are e.g. B. only be attached to an outer surface of the firework or on the casing of the firework.

According to a further aspect of the invention, a firework battery with at least one firework, in particular according to the invention, is claimed. Consequently, the firework of the firework battery has at least a first receiving part for a pyrotechnic effect and at least one ignition means connected to the pyrotechnic effect. In the fireworks according to the invention, at least one auxiliary ignition system can be provided, which can be ignited by the ignition means, an ignition flame being able to be generated by the auxiliary ignition system, and the ignition flame being able to be essentially led out from the fireworks, whereby at least one additional fireworks with pyrotechnic effects can be ignited. Accordingly, a firework battery according to the invention with at least one firework according to the invention, a further firework or and / or a further firework battery which is arranged at a distance from the first firework battery or the first firework can ignite without an existing fuse.

A firework battery according to the invention thus brings with it the same advantages as have been described in detail with reference to a firework body according to the invention.

Advantageously, the firework battery has at least one receiving part for at least one firework according to the invention and a border, which is connected via at least one hinge part to a further receiving part and / or an extension element extending the border, which is arranged on a receiving part, the axis of rotation of the hinge part being vertical is arranged to a floor, as a result of which the geometric arrangement of the receiving part and / or of the extension element can be moved relative to one another, as a result of which a rimmed standing area of the firework battery is enlarged.

According to the invention, at least one receiving part and / or an extension element can be fixed with at least one foldable support element. In this case, the support element can be formed over the entire surface, over part of the surface or only as a web in comparison to the receiving part or extension element. The support element can be folded from a transport position into a use position about a horizontal axis, the extension element having only a minor influence on the pack size in the transport position and the support element, the receiving part and / or the extension element being reinforced in an opened position in the use position. As a result, the receiving part and / or the extension element is held in its unfolded shape, so that the stability is thereby additionally increased and a displacement of the at least one receiving part or the at least one extension element is prevented. In addition, the surface of the support element also offers additional options for placing hazard warnings, instructions or advertising information.

It is also conceivable that at least one additional fireworks according to the invention can be accommodated in the base, in particular on the support elements, in particular at least one further fireworks can be fixed by at least one support element and / or a holding element. Due to the enlarged rimmed footprint of the firework battery when unfolded, new space is created in which at least one other firework can be accommodated, which in one collapsed state of the firework battery finds no place. The stand area thus becomes a receiving part for at least one firework, which further increases the stability of the firework battery. In addition, the number of fireworks within the stand area has a positive influence on the optical design and number of pyrotechnic effects.

A firework according to the invention arranged in the firework battery enables further fireworks arranged in the firework battery to be ignited via the auxiliary ignition system, in particular even if there is no connection to one another by means of an ignition cord. The auxiliary ignition system enables the fireworks to ignite each other even when the firework battery has a larger footprint, as a result of the receiving parts and / or extension elements being moved relative to one another. Consequently, after igniting a first firework of the firework battery, the auxiliary ignition system, which can be ignited by the ignition means, can produce an ignition flame, the ignition flame being led out essentially horizontally from the firework, whereby at least one additional firework with a pyrotechnic effect is ignited.

According to a further aspect of the invention, a method for igniting at least one second firework by a first firework is claimed, wherein the second firework is spaced apart and arranged contactlessly to the first firework and an auxiliary ignition system from the first firework ignites the second firework. Accordingly, a second firework can be ignited by the auxiliary ignition system of the first firework without a material connection to the first firework.

The described firework battery and the described method have all the advantages which have already been described for the fireworks according to the invention.

Elements and features with the same technical function and mode of action are in the Figures 1 to 12 each provided with the same reference numerals.

In Figure 1 schematically shows a firework battery 100 according to the invention with a firework 10 according to the invention, which here has, for example, at least one first receiving part 11 for a pyrotechnic effect 20 and at least one ignition means 40 connected to the pyrotechnic effect 20. The ignition means 40 connects in Figure 1 the auxiliary ignition system 30 with the pyrotechnic effect 20 and is led out by this through the receiving part 11 and the casing 12 and is thus accessible from the outside. The auxiliary ignition system 30, which can be ignited by the ignition means 40, is in the Figure 1 arranged in the first receiving part 11, the sheath 12 forming the outermost edge of the firework 10. The auxiliary ignition system 30 is arranged in the receiving part 13, an insulation element 50 which separates the auxiliary ignition system 30 from the pyrotechnic effect 20 is arranged on one side of the auxiliary ignition system 30. The receiving part 13 surrounds the auxiliary ignition system 30 on the remaining surfaces of the auxiliary ignition system 30, so that it is pyrotechnically connected to the pyrotechnic effect 20 only by the ignition means 40. The pilot flame 31, which is generated by the auxiliary ignition system 30, is led out essentially horizontally from the firework 10, so that the additional firework, spaced apart from the first firework 10, can be ignited by the pilot flame 31. The additional firework, which is spaced apart from the first firework, also has an ignition means 40, which is ignited by the pilot flame 31. The firework 10 points in Figure 1 a positioning aid 60 and a support aid 61 on the receiving part 11 of the firework 10. The positioning aid 60 or the support aid 61 can, according to the invention, for. B. foldable on the receiving part 11 or the casing 12 of the firework 10 may be arranged. In particular, the support aid 61 is preferably arranged in the vicinity of the surface with which the firework 10 is placed on the ground, so that the firework 10 can be supported on the ground via the support aid 61. The positioning aid 60, however, can be arranged anywhere on the firework 10 and can also be reversible, z. B. be arranged by locking, screwing or gluing. A further function of the positioning aid 60 or the support aid 61 results from the connecting means 63 according to the invention, which is arranged both on the positioning aid 60 and on the support aid 61. In this way, an at least mechanical connection can be established with at least one connecting means 63 arranged on an additional firework. Accordingly, it is conceivable that to the side of the Fireworks 10 on which the connecting means 63 is arranged, further fireworks are arranged and connected. This further increases stability. In Figure 1 the connecting means 63 is designed as a vertical slot 63 or incision 63 in the positioning aid 60 and the support aid 61. This slot 63 makes it possible, for example, for the positioning aid 60 to be inserted or nested into one another with the slot 63 of the support aid 61.

The Figure 2 schematically shows the auxiliary ignition system 30, which is arranged on a casing 12. The auxiliary ignition system 30 has in Figure 2 Via an insulation element 50 and via a receiving part 13. The ignition means 40 is guided from the outside through the casing 12 and the receiving part 13 and through the auxiliary ignition system 30 and emerges on another side of the receiving part 13 of the auxiliary ignition system 30. Accordingly, there is a connection of the ignition means 40 with the pyrotechnic effect 20 both above and below the auxiliary ignition system 30. This has the advantage that when the pyrotechnic effect 20 is ignited, the part of the ignition means 40 which is arranged in the pyrotechnic effect 20 can be lit in two places. Accordingly, the ignition means 40 can be ignited on the one hand below the auxiliary ignition system 30 by the pyrotechnic effect 20. On the other hand, there is the possibility that, in the case of a pyrotechnic effect 20 that burns from bottom to top, the ignition means 40 above the auxiliary ignition system 30 can also be ignited by the pyrotechnic effect 20. This results in a kind of fallback level, in the event that the ignition means 40 is not ignited at a first contact point with the pyrotechnic effect 20, the ignition means 40 is ignited by the second contact with the pyrotechnic effect 20. The auxiliary ignition system 30 is arranged on the casing 12 in such a way that the casing 12 forms the outermost edge layer of the firework 10. Accordingly, it is conceivable that the auxiliary ignition system 30 is connected to the casing 12 at a contact surface with the latter. This can be, for. B. is an adhesive, screw or a snap connection. The casing 12 thus forms a protective layer for the auxiliary ignition system 30, so that it is at least partially protected against environmental influences and / or forces.

The Figure 3 shows a firework 10 with a receiving part 11, wherein in the receiving part 11 in the Figure 3 there is no pyrotechnic effect. This is e.g. B. is conceivable if a pyrotechnic effect is not arranged in each firework in a firework battery 100, but an auxiliary ignition system 30 is present for igniting further fireworks and / or firework batteries. Hence in Figure 3 the auxiliary ignition system 30 is arranged in the receiving part 11 behind a casing 12 in such a way that the ignition means 40 penetrates the receiving part 13 of the auxiliary ignition system 30 at at least two points in the receiving part 13. Furthermore also in Figure 3 the auxiliary ignition system 30 has an insulation element 50, the insulation element 50 in this case in particular serving to direct the pilot flame of the auxiliary ignition system out of the receiving part 13 or out of the casing 12. Furthermore, in Figure 3 to recognize the safety element 62, which at least largely prevents the pilot flame from escaping. The Figure 3 also shows the horizontal axis of symmetry, with the radiation angle α being shown on the horizontal. The radiation angle α spans the area above and below the horizontal axis of symmetry, in which the pilot flame preferably spreads. Accordingly, the radiation angle α can extend in a range above the horizontal between 0 ° and 90 ° and below the horizontal between 0 ° and 90 °.

In Figure 4 The auxiliary ignition system 30 is shown, which is arranged directly on the casing 12, so that no receiving part 11 is required for receiving the second receiving part 13. The auxiliary ignition system 30 is arranged with the receiving part 13 directly on the casing 12, and according to the invention has z. B. via an adhesive, snap or screw connection. The ignition means 40 is carried out here both on the top and on the bottom of the receiving part 13 of the auxiliary ignition system 30. The insulation element 50 according to the invention, which is located on the side of the receiving part 13 of the auxiliary ignition system 30 opposite the casing 12, is also shown.

In Figure 5 A further embodiment of the auxiliary ignition system 30 is shown, the receiving part 13 of the auxiliary ignition system 30 being designed like a sleeve and together with the casing 12 forming the outermost edge of the firework 10. The ignition means 40 is in Figure 5 partially outside the firework 10 and from there is conducted into the auxiliary ignition system 30, so that the auxiliary ignition system 30 can also be ignited from the outside by the ignition means 40. From the receiving part 13 of the auxiliary ignition system 30, the ignition means 40 is guided out of the second receiving part 13 into the first receiving part 11. In this embodiment, the auxiliary ignition system 30 requires relatively little installation space, since it closes off the firework 10 directly with the casing 12 and is of relatively compact construction due to the sleeve-like shape.

In Figure 6 A further embodiment of the auxiliary ignition system 30 is shown, this being an ignition surface 30 which is protected against environmental influences by a casing 12 in the form of a label. The ignition device 40 is partially arranged outside the casing 12 and penetrates the casing 12 at one point in such a way that the ignition device 40 is guided along the sheet-like auxiliary ignition system 30 and from there into the first receiving part 11. In this embodiment, the auxiliary ignition system 30 has the smallest installation space, since the auxiliary ignition system 30 can be arranged between the receiving part 11 and the casing 12 without any problems due to the flat design.

In Figure 7 A firework battery 100 according to the invention is shown, the firework battery 100 in the embodiment having two support elements 112, which hold the receiving parts 111 in the use position in the unfolded position shown. According to the invention, the support elements 112 are connected to the one long side of the receiving parts 111 via a hinge part 114 and can be folded around the hinge part 114 in the transport position, so that the surface of the support elements 112 lies against the one surface of the long receiving part 111, so that in the transport position Firework battery 100 in the Figure 1 shown form assumes. According to the invention, the support elements 112 can have different sizes and do not have to stop over the entire longitudinal side of the receiving parts 111. The in the Figure 7 Support elements 112 shown have a large support effect for the receiving parts 111, since they cover a large part of the footprint 130 and thus come to a stop along the almost complete longitudinal side of the receiving parts 111.

The support elements 112 also cover the standing surface 130, so that on the one hand further information and / or advertising can be displayed on this spanned surface and on the other hand there is a surface that is protected against environmental influences and on which further fireworks 10 can be arranged , It is thus conceivable that the support elements 112 consist of a material that is at least partially moisture-proof and / or inhibitory, so that the stability of the support elements 112 through moisture does not have any negative effects.

The Figure 8 shows a further embodiment of the firework battery 100 according to the invention, in which a plurality of fireworks 10 are arranged in the clamped standing area 130. In the position of use shown, the receiving parts 111 form a square base 130 which forms enough space for further pyrotechnic sets 20. It is conceivable here that further fireworks 10 are arranged on a carrier, which is arranged in the use position of the firework battery 100 between the receiving parts 111 on the standing surface 130, so that the number of fireworks 10 is significantly increased, as a result of which the pyrotechnic effects of the firework battery 100 result in a greater variety in appearance.

The arrangement of the additional fireworks 10 on a carrier in the base 130 thus results in a comparable effect to that achieved by the support elements 112. In this way, a displacement of the receiving parts 111 from the use position into the transport position is prevented, so that increased security is ensured. Accordingly, in the embodiment according to Figure 8 Numerous advantages, which in addition to increased safety also result from a positive influence on the pyrotechnic effects or the number of pyrotechnic effects.

In the Figure 9 A further embodiment of the firework battery 100 according to the invention is shown, which are formed by three receiving parts 111, in which a plurality of fireworks 10 are arranged. In the transport position shown, the border 113 has the smallest possible extent of the embodiment shown. An auxiliary ignition system 30 according to the invention is arranged on the outer receiving part 111, which enables a firework of another firework battery to be lit. To do this, it is only necessary to position the additional firework battery with an ignition means or an auxiliary ignition system arranged on the additional firework battery in such a way that it can be ignited by the ignition flame.

The Figure 10 shows the further embodiment of the firework battery 100 according to the invention, which is also shown in FIG Figure 9 is shown, the extension elements 115 arranged between the receiving parts 111 being recognizable in the first transport position shown. In the first use position shown, the three receiving parts 111 are arranged at a distance from one another like an accordion, so that the extension elements 115 have acute angles between the receiving parts 111. As a result, the spread base 130 of the firework battery 100 is compared to that in FIG Figure 9 shown transport position significantly enlarged. The border 113 is extended by the extension elements 115 shown, so that the receiving parts 111 are connected by the extension elements 115, so that there is increased stability of the firework battery 100. In Figure 10 all three receiving parts 111 each have an auxiliary ignition system 30. The auxiliary ignition system 30 of the middle and rear receiving part 111 is arranged on the inside. It is thereby achieved that the pilot flame of the rear auxiliary ignition system 30 can ignite the fireworks 10 of the central receiving part 111, an auxiliary ignition system advantageously being arranged on the central receiving part 111, which is opposite the auxiliary ignition system 30 of the rear receiving part (not shown here specifically). The illustrated auxiliary ignition system 30 of the central receiving part 111 is also arranged such that a firework 10 of the front receiving part 111 can be ignited by an ignition flame of the auxiliary ignition system 30. Analogous to Figure 9 an auxiliary ignition system 30 according to the invention is arranged on the outer / front receiving part 111, which enables a firework of another firework battery to be ignited.

In addition, in the Figure 10 an ignition cord 140 with an ignition cord end 140.1 is shown, which is arranged on a receiving part 111 and is used to ignite at least one firework 10.

The Figure 11 shows a further embodiment of the firework battery 100 according to the invention in a second position of use, in which the spread standing area 130 is the largest. In this case, the extension elements 115, compared to that in FIG Figure 10 shown shape, a flat surface, so that the standing surface 130 spanned between the receiving parts 111 is largest. Also in Figure 11 The receiving parts 111 are shown with the auxiliary ignition system according to the invention, so that even in the second position of use, fireworks 10 of the receiving parts 111 arranged in parallel are made possible.

Depending on the length of the extension elements 115, the distance between the individual receiving parts 111 can be made larger or smaller. In this case, however, the receiving parts 111 are always spaced parallel to one another. It is conceivable that both a rectangular and a trapezoidal arrangement of the firework battery 100 is made possible.

Figure 12 shows two fireworks 10, each with a receiving part 11 and pyrotechnic effects 20 arranged therein. Positioning aids 60 are arranged on the casing 12 of the receiving parts 11. The positioning aids 60 each have a connecting means 63, two laterally arranged positioning aids 60 being in the open position in which the two connecting means 63 and positioning aids 60 are inserted one into the other. For this purpose, the connecting means 63 on the positioning aid 60 is designed as a slot 63, so that they can be interconnected. On the broadside / transverse surface, two further positioning aids 60 are arranged on the front firework 10, which are formed from the casing 12 and have a perforation 64 and an opening aid 65, so that the positioning aids 60 with the connecting means 63 arranged thereon, simply out of the casing can be solved. Accordingly, in Figure 12 , The positioning aids 60 shown in the foreground are shown in a closed position on the receptacle 11, an ignition means 40 being arranged on the receptacle 11.
