Description

The present invention relates to a fireworks body assembly comprising at least two fireworks and a bottom plate with arranged on an upper side of the bottom plate receptacles for the at least two fireworks, as well as a corresponding bottom plate.

Commercially available fireworks are sold to end users, not only in the form of individual firecrackers, but also increasingly in the form of so-called battery fireworks, in which several individual fireworks are arranged in groups, and in which the individual fireworks inside with each other Connection stand. In such battery fireworks then depending on the type of making the inner connection (entrainment) targeted a firing of the individual fireworks can be triggered. An exemplary battery firing assembly is shown in FIG EP 1 262 730 A2 disclosed. The individual firecrackers are loosely received in a receiving part, which is similar to an outer packaging, an alignment of the individual fireworks to each other takes place by the mutual attitude and support of the respective firecracker sleeves with their contact surfaces together.

A disadvantage of these known from the prior art battery fireworks, however, is that on the one hand the exact, usually parallel alignment of the occasionally recorded in a recording fireworks just after firing one or more fireworks from such a battery plant fireworks remaining in the same is affected, and in the production of such battery fireworks due to the necessary exact alignments of the respective occasionally recorded firecrackers must be worked with great effort. On the other hand, it is only known to purchase already ready-made battery fireworks, in which the manufacturers already installed the occasional firecrackers and the firing order is predetermined. However, there is a need, as far as permissible in the private, but also in the professional field, to provide fireworks arrangements with which a battery rework can be simply and possibly also reused by the user, whereby the ignition sequence can also be determined by the user.

It is therefore an object of the present invention to provide a fireworks assembly as well as a bottom plate for fireworks available, which avoids the above-mentioned, known from the prior art disadvantages and meets needs.

This object is achieved by a fireworks body comprising at least two fireworks and a bottom plate with at least two arranged on top of the bottom plate receptacles each for at least one fireworks, wherein the bottom plate on a bottom at least one elongated, open in the direction of a surface of the bottom recess Igniter and at least one Überzündungsstelle per firecracker body, wherein the Überzündungsstelle is disposed in the region between the recess and a receptacle. Depending firecracker each receiving a receptacle is preferably provided. The great advantage of the fireworks arrangement according to the invention is that due to the arrangement of at least one elongated recess on the underside of the bottom plate on the one hand the end user, where permitted, can assemble his own fireworks himself, in particular the firing order by laying appropriate ignition in the elongated, in particular channel-shaped Recess and assignment of fireworks to the appropriate recordings can set. In addition, it is advantageously achieved that flames in the opening direction of the elongated receptacle, that can escape towards the surface of the underside of the bottom plate, whereby a pressure distribution or pressure relief that occurs during ignition takes place, which reduces the risk of over-firing the fireworks with each other. It is therefore ensured that the over-ignition is provided only by the appropriate ignition means, and not by an uncontrolled over-firing of the fireworks with each other. Such an advantage can not be achieved, in particular, if the recess were to be arranged on the upper side, in which case the flames must escape to the side and thus the risk of fireworks overestimating one another increases.

The base plate may be formed in one or more parts, in particular, it may also be modular plug-in, wherein the aforementioned expert corresponding connection means are known, for example, conventional connectors, such as those with protruding sleeves or the like. At least one fireworks body should be able to be accommodated per modular subelement of the base plate. Preferred is a one-piece design.

The elongate recess may have any cross-section, for example a semicircular, semi-oval, or quadrangular cross-section, wherein the corners may be rounded. Particularly preferred is a rectangular or square cross-section.

The shots for the fireworks can be designed in various ways. In the simplest case, they can simply be arranged as recesses on the upper side of the base plate, in which the individual fireworks, which are generally designed in the form of a cylinder tube, are set up in such a way that a firing cord the same engages through the Überzündungstelle in the elongated recess in which a igniter is guided. However, it may alternatively be provided, for example, that the receptacle for the fireworks is formed by a sleeve-like receptacle, which is arranged on the upper side of the bottom plate, and is securely connected by means of a circumferential collar with the top of the bottom plate. But any other type of training recording is conceivable.

In a preferred embodiment of the present invention, the elongated recess has at least one undercut near the surface. The term "near-surface" in the context of the present invention is understood to mean that, starting from the surface of the underside, the undercut is arranged in the recess in a region which corresponds to a maximum of about 50% of the total depth of the elongated recess, starting from the surface of the elongated recess Bottom of the bottom plate. Preferably, the undercut is no further from the surface of the underside of the bottom plate in the interior of the elongated recess than about 30%, based on the maximum depth of the elongated recess. Preferably, at least two undercuts are provided which are associated with the longitudinal sides of the elongated recess. The arrangement of the undercuts makes it possible that ignition means such as in particular ignition cords and Stoppines are simply einklickbar in the elongated recess, which greatly facilitates the self-assembly by the end user. The undercut can be designed for this purpose in any manner known to those skilled in the art, and preferably has a skew in a range of about 30 ° to 60 °.

Igniter in the context of the present invention are the abovementioned Stoppins, but also igniter, especially self-adhesive, as well as igniting cords, such as so-called Bickford's ignition cords, ignition strands or the like.

The bottom plate may be made of any material usable for the stated purpose. Particular mention should be made of cardboard materials, plastic materials, as far as suitable for fireworks, and / or metallic materials. The receptacle for the fireworks can be formed from these materials.

Preferably, in the fireworks arrangement according to the invention, at least two overfire sites are provided per fireworks, more preferably at least three. This makes it possible to adjust the delay time between the fireworks. Because, depending on how the firing line of the fireworks body is guided in the elongated recesses, the over-ignition takes place between the firing means arranged in the elongate recess and the firing cord of the fireworks body sooner or later.

In a further preferred embodiment of the present invention, the over-ignition point is formed as a bore between the receptacle for the fireworks and the elongated recess. The bore can have any possible cross-section, in particular, the hole does not have to have a round cross-section, but may for example also be square, rectangular, hexagonal, octagonal or n-square executed. Preferably, the bore is formed with a width which is only slightly wider than the diameter of a firing line of a fireworks body, so that after insertion of the fireworks body into the receptacle on the bottom plate slipping out of the firing of the fireworks body from the Überzündungstelle be avoided.

The firework body arrangement according to the invention can have at least two intersecting recesses in an advantageous embodiment. Then recordings for fireworks are preferably arranged at the intersection. But any other embodiment of at least one elongated recess on the underside of the bottom plate is possible, for example, one in which serpentine or S- or double S-shaped only a single or more recesses are formed on the underside of the bottom plate, also without crossing each other. Also, no uniform crossing pattern must be provided, for example, only individual elongated recesses may intersect, while others may have no intersection. Also, for example, a grid or diamond-like arrangement of the recesses is possible.

In a further preferred embodiment of the present invention, at least one widening is provided in the region of at least one mouth of a recess at an edge of the bottom plate. In providence exactly an elongated recess on the underside of the bottom plate of this is preferably associated with at least one mouth, but preferably two mouths, for example, in a linear, rectilinear design of the at least one recording in a quadrangular base plate such a, in which the mouths to the opposite Side edges of the quadrangular bottom plate are formed substantially opposite one another. The widening in the region of at least one opening advantageously creates the possibility of arranging there the ignition means with its one end, so that it does not protrude beyond the outer contour of the base plate. As a result, the subsequent packaging, in particular not a self-assembly by the end user, is considerably simplified, since this can be easily ignited in the expansion of the igniter.

In a further preferred embodiment of the present invention, the igniter is held by glue in the elongated recess, more preferably by injection molding. The injection molding process is particularly applicable to firing cords and Stoppinen. In a further embodiment of the present invention, the bottom plate can be arranged on a base plate. The connection between the base plate and the base plate can be done in any way, for example, by a simple clamping, so that the base plate is repeatedly used repeatedly. Baseplate and / or bottom plate may also include foot elements to allow for spaced placement of the fireworks assembly on a footprint. The foot elements may in particular also be adjustable, in particular height-adjustable, so that an exactly parallel alignment of the arrangement according to the invention can be achieved.

Furthermore, the present invention relates to a floor panel as used in a fireworks assembly according to the present invention. The bottom plate in this case has, in particular on a top side, at least two receptacles for at least one fireworks body, an elongated opening for igniting means being open in the direction of a surface of the underside of the bottom plate, and at least one overcrowding point being provided for each firecracker body, wherein the Überzündungstelle is arranged in the region between the recess and a receptacle.

The fireworks assembly according to the invention can be made available to the end user in a completely prefabricated form, but the end user can also be provided separately, for example, the bottom plate, on the other fireworks and igniter so that it can make a self-assembly of fireworks arrangement. Finally, provision may also be made for additionally arranging ignition compound in the at least one elongated recess of the base plate, in particular in the region of over-ignition points, in order to ensure the ignition of igniter agent on the firing line of the fireworks body. Incidentally, the firecracker may preferably be designed as a cylinder or ball bombette or with a fire stop function with loose stars, bang or whistle cartridges.

First, it should be noted that the invention is not limited to the feature combinations shown in the figures. Rather, the features disclosed in the description including the description of the figures can be combined with those features indicated in the figures. Furthermore, it should be noted that the reference numbers incorporated in the claims in no way limit the scope of the present invention, but merely refer to the embodiments shown in the figures. Furthermore, it should be noted that the exemplified in the figures training the bottom plate in a square shape only simplifies the presentation, and the bottom plate may have any other shape. In particular, the base plate can also be formed in several parts, with the individual modules then ultimately form a bottom plate via connectors. The formation of the receptacle for the fireworks body, which is selected in the figures, is merely exemplary, other embodiments of the recording, as these are reproduced in particular in the general description, are readily possible.

Fig. 1 shows a generally designated by the reference numeral 10 first embodiment of the fireworks body assembly according to the invention in a bottom view with a bottom plate 14 with a bottom 18. Schematically, the arrangement of a total of four fireworks 12.1, 12.2, 12.3 and 12.4 on the bottom side facing away from the top 16th (see also Fig. 2 The firecrackers 12.1 to 12.4 are cylindrical section-shaped, in particular as a cylinder or Kugelbombette or with a Feuertopffunktion be formed with loose stars, bang or whistle cartridges, and accordingly have a circular diameter.

The bottom plate 14 has side edges 22.1, 22.2, 22.3 and 22.4, in which mouths 38 (for example, for receiving 26.2 are the mouths 38.21 and 38.22 referred to in Fig. 1 ) of a total of three linear and rectilinear elongated recesses 26.1, 26.2 and 26.3 open. These elongate recesses 26.1, 26.2 and 26.3 are approximately square in cross-section (see Fig. 3 ), wherein the elongated recesses 26.1 and 26.2 are parallel to each other and thereby pulled through to the side edges 22.1 and 22.3 of the bottom plate 14. The elongated recesses 26.1 and 26.2 are crossed at right angles by an elongated recess 26.3.

The elongate recess 26.2 has on the side edge 22.3 of the bottom plate 14 has a rectangular-shaped extension 40, in which a not shown here inserted Igniter can be pressed so that it does not protrude beyond the outer contour, defined by the side edges 22.1 to 22.4, the bottom plate, and thus a simple packaging when prefastening the fireworks arrangement is possible.

Furthermore is Fig. 1 to recognize that in the bottom plate 14 Überzündungsstellen 30 are arranged, which in a region between the elongated recesses 26.1 to 26.3 and the not shown in detail receptacles 24 (see Fig. 2 ) disposed on the upper surface 16 of the bottom plate 14. In this case, as illustrated, for example, with respect to the fireworks 12.4, only a single Überzündungstelle 30.1 be provided, but also, as shown on the fireworks 12.2, also a total of three Überzündungstellen 30.2, 30.3 and 30.4 be associated with a fireworks. Depending on which bore the ignition cord 13 (see Fig. 2 ) of the fireworks body 12.2 is first passed, starting from the location of the ignition, for example, starting from a recorded in the extension 40 end of an igniter, there is a staggered over-ignition, so that thereby a fine adjustment from the factory or by the end user in self-assembly in terms of the sequence of fireworks achievable with the fireworks arrangement can be taken.

Fig. 2 shows a sectional view through the bottom plate 14 of the embodiment according to Fig. 1 , wherein the arrangement of the Überzündungsstellen 30.1 to 30.4 and the arrangement of Anzündschnüren 13.1 or 13.2 from firecrackers not shown in detail here 12.4 and 12.2 according to particularly clarified Fig. 1 the fireworks assembly 10 according to the invention. The receptacles 24.1 and 24.2 are circular in shape, and convey with the use of fireworks 12 in this sufficient support. The Überzündungsstellen 30.1 to 30.4 are seen in cross-section circular, which also in the other fireworks 12.1 and 12.3 according to Fig. 1 the fireworks assembly 10 may be the case.

Fig. 3 shows the detail X the Fig. 2 in a detailed view, from which in particular the approximately square cross-section of the elongated recess 26.3 is apparent, wherein a base 36 is formed, which is provided on both sides with a soft curve merges into side walls 34.1 and 34.2 of the elongated recess 26.3. In this an ignition means 28, such as a Stoppine, is recorded, which is in contact with both the base 36 and the side walls 34.1 and 34.2, but need not. The inside width of the elongated recess 26.3 is chosen so that it corresponds approximately to the diameter of the igniter 28 (+/- 5%). This may also be the case with the further elongate recesses 36 of the fireworks body arrangement 10, and is otherwise also preferred in the context of the present invention. On the side walls 34.1 and 34.2 opposite undercuts 32.1 and 32.2 are formed, which have a skew at an angle of 45 °. This makes it possible to simply press the Stoppers 28 in the elongated recess 26.3 and this to give a firm grip, which is avoided by the undercut 32.1 and 32.2 falling out of the Stoppine 28 from the elongated recess 26.3.

In the in the Fig. 1 to Fig. 3 shown first embodiment of the fireworks body assembly 10 is a variety of ways how the igniter 28 can be performed in the recesses 26.1 to 26.3. For example, the igniter can be pressed starting from the widening 40 via the mouth 38.22 in the elongated recess 26.2 and so over the Überzündungstellen 30 fireworks 12.4 and 12.3 cause the same, then then kinking at right angles to the fireworks 12.3 in the elongated recess 26.3 to be performed on the fireworks body 12.2 and in the area of Überzündungsstellen 30.2 to 30.4, then there at right angles to the left bent on the fireworks 12.1 with another three Überzündungstellen 30 to be performed. However, it would also be possible, for example, to introduce an ignition means 28 via the mouth 38.21 of the elongate recess 26.2 (whereby a widening 40 could be provided on the side edge 22.1 in the region of the mouth 38.21), and the igniter means 28 onto the over-ignition sites 30 of the fireworks 12.3 and 12.4, and thereby provide a diversion such that another branch of the igniter 28 is guided by the fireworks body 12.3 on the fireworks 12.2 to the fireworks 12.1. But also a variety of other possibilities of the arrangement of igniter 28 in the recesses 26 is conceivable. From the above it is clear that the igniter can also be designed in several parts in the meaning of the invention, and in particular can have branching points.

Fig. 4 now shows a second embodiment of the fireworks assembly 10 according to the invention, wherein a square bottom plate 14 with now a total of nine fireworks 12, which are schematically indicated, is provided on the underside 18, a single recess 26 S-shaped with mouths 38.11 and 38.12 in Each Firecracker 12 is exactly one Überzündungstelle 30 is provided so that in each series of three an equal distance between the Überzündungstellen is given and accordingly takes place at the same time over time ignition takes place in each row of three, whereas when changing the Threesome due to the longer way a delay of the over-ignition occurs.

By the present invention, a fireworks body assembly as well as a bottom plate is provided for this, which a simple assembly, in particular self-assembly by the end user, allows for a simultaneously high variability of the pyrotechnic effects to be achieved by arranging a or more Überzündungsstellen and specific leadership of igniter with specific arrangement of one or more elongated recesses on the underside of the bottom plate.
