Description

The invention relates to a pyrotechnic device for creating a total effect consisting of separate effects.

To create a pyrotechnic cumulative effect, the ignition of so-called bombs is known, which, after reaching a certain height of rise, explode to present a two-dimensional effect. When rising, the bomb rotates around its own axis along the flight path. The orientation of the bomb is not possible. There is a risk that the effect of the bomb on the observer due to erroneous orientation during the explosion will be invisible.

With a light picture, the so-called Bengal lights are fixed on a stand. Due to its own weight, such a stand can be ignited solely on the ground.

The utility model is based on the task of improving the pyrotechnic device to create a total effect consisting of separate effects.

The problem is solved in a pyrotechnic device for creating a total effect consisting of separate effects, containing several tracer firecrackers, each of which has an ignition element, at least one luminous charge, and an ignition control system connected to the ignition elements to ignite the tracer firecrackers, and the tracer firecrackers are located in a pyrotechnic means at different angles of inclination relative to each other so that each of the rising luminous charges in represents a separate effect of the total effect, and the mass and volume of the ignition elements of at least two tracer firecrackers are set different.

The essence of the utility model is that many tracer firecrackers, which leave a luminous trace when rising, serve as separate effects to represent the overall effect. The cumulative effect is, for example, a graphic symbol, primarily a smiley or a heart. But the overall effect can also be a printed sign, primarily a letter or number. First of all, the total effect can be a word consisting of several letters and, above all, a stroke or a multi-digit number. It is possible to create any graphic images and symbols. Individual effects are individual points of the image, and the total effect is the overall picture that arises from the individual points of the image. Due to the fact that a separate effect is visible to the observer as an image point followed by a luminous trace during the raising of the tracing firecrackers, the total effect is visible for a relatively long period of time. A tracing firecracker can be performed without a subsequent luminous trace. With this design, a separate effect consists of a rising point of the image. The pyrotechnic device according to the utility model is shot into the air and is not limited to being used as a ground firework. Tracing firecrackers as a pyrotechnic device are primarily spatially relative to each other so that the individual effects represent the total effect. Each tracer firecracker has an ignition element and a luminous charge, and the ignition of the ignition element with a luminous charge represents an image point with a luminous trace. The pyrotechnic device comprises an ignition control system for, first of all, delayed ignition of tracing firecrackers. The ignition control system is connected to the ignition elements of the tracer firecrackers. First of all, the orientation of the tracer firecrackers is insignificant, since the luminous trace of the luminous charge is visible to the observer, regardless of the orientation of the tracer firecrackers, when rising. The danger of misconception is averted. First of all, tracing firecrackers ignite with a time shift to ensure that the individual effects are located at different distances from each other along the direction of rise. Advantageously, tracing firecrackers are fixed in a pyrotechnic means. It is especially favorable if the tracer firecrackers are located in the pyrotechnic means at different angles of inclination to each other. This makes it possible to directly and easily determine the total effect. The individual effects rising at different angles of inclination, primarily relative to the substrate (horizontal), create a cumulative effect, and the individual effects are ignited in time so that they are (clearly) visible at a predetermined distance equally distant with respect to the device. A pyrotechnic device in which tracer firecrackers are located in a pyrotechnic means makes it possible to concentrate tracer firecrackers in one object. Such a pyrotechnic means corresponds to a so-called battery, which is placed on a substrate. Tracing firecrackers are fixed in the battery. It is not possible to extract individual tracer firecrackers from a pyrotechnic product without destroying the pyrotechnic product.

The pyrotechnic device in which the tracer firecracker has a firing sleeve having a longitudinal axis provides reliable and error-free ignition. The ignition sleeve is made primarily in the form of a hollow cylinder. Other hollow profile shapes are also possible. First of all, the ignition element and the luminous charge are located in the ignition sleeve. The ignition sleeve protects the ignition element and the luminous charge from atmospheric influences, dampness and / or inadvertent damage. For this, it is particularly preferable to perform a pyrotechnic device so that (in the assembled state) the ignition sleeve is oriented at an angle from 0 ° to 70 °, especially from 15 ° to 45 ° to the horizontal. For this, in addition, it is particularly preferable to perform a pyrotechnic device so that (in the assembled state) the ignition sleeves are oriented so that it is possible to produce vertically directed effects. With a vertically directed effect, the luminous bodies are directed vertically in a plane so that an image that appears equidistant from above and below is produced relative to the position of the device. For this, the lower ignition charges must be charged less strongly than the ignition charges for the upper part of the image in order to produce different flight times t to a predefined image point.

Due to the fact that the mass and volume of the ignition charge of at least two tracer firecrackers are set different, an adjustable, adjustable lift height of the luminous charge is provided. Due to this, the rising total effect during the rise can change in geometry, first of all, to stretch or flatten your contour. It is possible that the rising total effect goes out simultaneously with the different elevation heights of the individual effects, that is, first of all, when the individual effects have reached their respective individual elevation. Thanks to at least two tracer firecrackers with differently set ignition charges, different times t of flight of individual luminous charges to the corresponding image point in the vertical picture can be obtained. Flight times t are essentially determined by the angle of the ignition sleeve to the horizontal.

The technical result achieved by the implementation of the utility model is to create a pyrotechnic device that expands the possibilities of creating cumulative effects by influencing the height of the luminous charges through the mass and the volume of the corresponding ignition charges in combination with the inclined relative position of the tracer firecrackers.

Tracing firecrackers are primarily fixed in the housing, for example by gluing or using mechanical fasteners. Such a pyrotechnic product is error-free and easy to handle and, above all, can be used pyrotechnically not prepared by the end user. Tracing firecrackers are located primarily in the body of the pyrotechnic means.

A pyrotechnic device in which the ignition control system has an ignition cord, which, first of all, directly connects two tracing firecrackers to each other, makes simple ignition possible.

The pyrotechnic device, in which the portion of the ignition cord of the ignition cord determines the time shift between the two tracers that are adjacent to the ignition in time, provides direct and simple establishment of the time sequence of ascending tracers.

The pyrotechnic device, in which the section of the ignition cord, is primarily directly connected to the ignition elements of the tracer firecrackers to be ignited, is error-free.

A pyrotechnic device in which tracer firecrackers, primarily their luminous charge, has a maximum height of 70 m, is clearly visible to the observer of the fireworks.

Such a pyrotechnic device may also correspond to the maximum permissible lift height for pyrotechnic products in class II. Class II pyrotechnic products correspond to New Year's fireworks and are suitable for use by end users.

The pyrotechnic device can also have a tracer firecracker whose luminous charge has a lower elevation, for example, from 5 m to 15 m. Such a tracer firecracker is made, first of all, in the form of a Roman fire. Roman fire is usually ignited while it is being held, that is, out of hand.

As an alternative to the fixed arrangement of the tracer firecrackers in the pyrotechnic means, the pyrotechnic device may be configured such that the tracer firecrackers are configured to be mutually arranged relative to each other.

This means that tracing firecrackers are mutable. The pyrotechnic device forms an unified pyrotechnic means and is intended, first of all, for use by pyrotechnically trained specialists.

The pyrotechnic device may have several holders, respectively, to accommodate one tracing firecracker. Holders can be mounted on a stand. The support makes possible a reliable and error-free arrangement of the pyrotechnic device, primarily on the substrate. Holders can be positioned on the stand spatially flexible. First of all, it is possible to change the spatial arrangement of the holders relative to each other on the stand. Due to this, it is possible to create various total effects using a pyrotechnic device. First of all, it is not necessary to equip all holders with tracer firecrackers.

In the pyrotechnic device, the holders can be located, first of all, in the correct raster. For example, we are talking about a rectangular raster. The raster is made, first of all, two-dimensional. First of all, the holders are oriented parallel to the bottom of the stand and, above all, at identical angles of inclination to each other. The holders are oriented essentially vertically and, above all, parallel to each other.

A pyrotechnic device does not require a separate safety approval. As a result of the fact that the quantities held are flexible and variable, the pyrotechnic device itself is not a separate pyrotechnic product, which would require a separate single European approval according to European standards or the approval of the Federal Office for the Study and Testing of Materials. Tracer firecrackers themselves require a single European clearance. To create a total effect, individual tracing firecrackers are combined by a trained pyrotechnic specialist, as a result of which a new pyrotechnic product is not created.

In the pyrotechnic device in which the ignition control system has an ignition device, the central, first of all, remotely controlled ignition of the pyrotechnic device is simplified. The ignition device is primarily electrically controlled. The ignition elements of the tracer firecrackers are connected, first of all, with electrical connection terminals. The connecting terminals are primarily suitably controlled by means of an ignition device.

Alternatively, the pyrotechnic device may correspond to class IV pyrotechnic means, for ignition of which pyrotechnic preparation is required in Germany.

FIG. 6: a top view of the pyrotechnic device according to FIG. four,

FIG. 7: An exemplary representation of a pyrotechnic device according to FIG. 4 total effect.

Depicted in FIG. 1-3 pyrotechnic device 1 is made as a pyrotechnic product in the form of pyrotechnic means. The pyrotechnic means is made according to the shown embodiment as a battery. In principle, other forms of pyrotechnic means are also possible.

The pyrotechnic means comprises a rectangular parallelepiped-shaped housing 2 with a bottom 3 and side walls 4. On the opposite bottom 3, the upper side of the housing 2 is open. A removable cover, not shown, may be arranged on the upper side to protect the interior of the housing 2 for storage and / or transportation. At the bottom 3, several tracer firecrackers are fixed 5. According to the illustrated embodiment, the tracer firecrackers 5 are glued to the bottom 3. The tracer firecrackers 5 are substantially identical.

The tracer firecrackers 5 have a cylindrical ignition sleeve 6. The ignition sleeves 6 respectively have a longitudinal axis 7. The tracer firecrackers 5 are fixed in the housing 2 at different angles of inclination of the corresponding longitudinal axis 7 relative to the bottom 3. First of all, the tracer firecrackers 5 have different angles of inclination relative to each other friend.

The inclination angles relative to the (horizontal) bottom 3 are from 0 ° to 70 °, especially from 15 ° to 45 °.

According to the embodiment shown, in the pyrotechnic device 1 there are fourteen separate tracer firecrackers. Depending on the total effect to be presented using the pyrotechnic device 1, more or less than fourteen firecrackers 5 can also be provided.

The tracer firecrackers 5 have, respectively, an ignition element 8 and a luminous charge 9. The ignition elements 8 of the tracer firecrackers 5 are respectively connected to the ignition control system. The ignition control system serves for delayed ignition of the tracer firecrackers 5. The ignition element is also called a moving charge, since it accelerates the luminous charge 9. After ignition, the ignition element 8 can be selected accordingly.

This is, above all, about the charge of black powder, the amount of which is selected in accordance with the desired acceleration (and flight range) of the luminous charge 9.

The luminous charge 9 is the so-called comet charge. After igniting the luminous charge 9 through the ignition element 8, the luminous charge causes a visual effect such as a meteorite. The luminous charge rises with a luminous point located at the top along the longitudinal axis 7, followed by a luminous trace.

The luminous charge is long visible along the direction of rise to the maximum rise height in the form of a luminous dot and a luminous trace. The direction of rise is determined by the longitudinal axis 7 of the ignition sleeve 6. Due to the influence of gravity on the ignition sleeve 6, the direction of rise by sections can be made in the form of a parabola.

Due to the high speed of the shot and the relatively small mass of tracer firecrackers 5, the curvature of the direction of rise is essentially unstoppable. This means that the direction of rise is formed essentially as a continuation of the longitudinal axis 7 of the ignition sleeve 6. A luminous dot forms an image point.

Tracing firecracker 5 can be performed as a standard, in itself well-known, comet. Alternatively, tracer firecracker 5 can also be implemented as a bomb, in which a fragmenting charge is additionally provided, which in a predetermined manner ignites with a time shift relative to the luminous charge 9.

Depending on the mass and volume of the ignition elements 8, the lift height of the luminous charge 9 is set. The greater the mass and / or the volume of the ignition elements 8, the greater the lift height. Tracing firecrackers 5 may also differ in mass and volume of the ignition elements 8. Thus, it is possible to achieve different heights of the lifting points 21 of the image. First of all, it is also possible to set the mass and / or volume of the various ignition elements 8 identical.

The timing is made in the form of an ignition cord 10. The ignition cord 10 connects respectively two tracing firecrackers 5 directly to each other. The ignition cord 10 has several sections 11 of the ignition cord, and each section 11 of the ignition cord directly connects to each other two time-flammable tracing firecrackers 5, especially their ignition elements 8. By establishing the length of the individual sections 11 of the ignition cord, a time shift is established when igniting tracer firecrackers 5, which are connected to each other by section 11 of the ignition cord. This ensures a reliable, error-free ignition process. First of all, it is ruled out that as a result of erroneous maintenance by the user, an unrecognizable or unesthetically formed cumulative effect could occur.

Further, the principle of operation of the pyrotechnic device 1 is explained in more detail. By igniting the ignition device, due to the series connection of the tracing firecrackers 5, they ignite sequentially, with a temporary shift. As a result of ignition of the ignition elements 5, the luminous charge 9 is fired from the ignition sleeve 6 along the longitudinal axis 7. The ignition elements 5, after ignition, cause the luminous charge 9 to move from the ignition sleeve 6. Due to the different angles of inclination of the longitudinal axes 7 relative to the bottom 3 of the housing 2, the luminous charges 9 are fired from the battery in different directions. When the luminous charges 9 rise, they produce a luminous point 21 at their apex and leave a luminous trace 22. Shot luminous charges 9 fired with a time delay and in different directions of flight produce a cumulative effect. The cumulative effect of FIG. 1 represents the outline of the heart, which is indicated by luminous dots 21. Luminous dots 21 represent individual effects.

Hereinafter, with reference to FIG. 4-7, a second embodiment of a utility model is described. Structurally identical parts retain the same reference designations as in the first embodiment, the description of which is then indicated. Structurally different, but functionally identical parts retain the same reference designations with the addition of the letter “a”.

In the pyrotechnic device 1a, the tracing firecrackers 5 are located in the holder 12 respectively provided for this on the stand 13. The support 13 has a beam-shaped base 14, on the upper side of which the holders 12 are fixed. It is also possible that the base is made in the form of a tray, so that the holders are located in bounded by a perimeter passing through the perimeter of the jumper with an offset downward with the groove.

The stand 13 has several support legs 15 for the reliable location of the stand 13 on the ground. The support legs 15 are firmly connected to the base 14. First of all, the support legs 15 are welded to the base 14. The stand 13 is made of metal. Other forms of implementation are possible. The support legs 15 can be made with the possibility of height adjustment, first of all, to compensate for the unevenness of the terrain on which the stand 13 should be installed. The support legs 15 can also have rollers to simplify the movement of the stand.

The holders 12 according to the shown embodiment are made in the form of V-shaped profile elements, the longitudinal axis of the profile being parallel to the longitudinal axis 7 of the tracing firecrackers 5. Due to the V-shape of the holder 12, tracing firecrackers 5 of various design sizes can be reliably held. First of all, the outer diameter of the ignition sleeve 6 is not essential for a specific and reliable location on the holder 12. At the opening of form V, the holder 12 has an additional holding element 16, which, for example, can be made in the form of a tape or belt, or a clamp. The holding element 16 prevents the situation when the tracer firecracker 5 is inadvertently detached from the abutting position on the holder 12. Unintentional tipping of the tracer firecracker 5 is prevented

Tracing firecrackers 5 are located on the stand 13 so that the longitudinal axis 7 are oriented parallel to each other and, above all, vertically. Tracing firecrackers 5 can be located on the base 14, for example, along a row, as shown in FIG. 6. This arrangement in a row corresponds to a regular, one-dimensional raster. It is also possible to provide a two-dimensional, especially correct, raster for locating the holders 12 on the stand 13. The holders 12 are variablely fixed on the stand 13 by means of fasteners not shown. For example, it is possible that the base 14 is made in the form of a perforated plate into which the holders can be screwed in the corresponding positions of the raster.

The ignition control system has electrically controlled connecting terminals 17. The connecting terminals 17 are directly connected to the ignition elements 8. For each tracing firecracker 5, one connecting terminal 17 is provided. The connecting terminals 17 are electrically conductive wires 18 respectively connected to the ignition elements 8.

In FIG. 7 in a simplified form shows how the total effect in the form of the letter Z is represented using a pyrotechnic device. As a result of the fact that the tracer firecrackers 5 with longitudinal axes 7 are parallel to each other, the image points can be shot parallel to each other. So that several luminous points 21 can be ignited along the luminous track 22, for example, several supports 13 can be arranged next to each other. It is also possible to place holders 12 on the stand 13 along the longitudinal direction 19 and along the transverse direction 20 with an offset relative to each other friend, primarily in several rows.
