A POLYSTYRENE SUPPORT BASE FOR FIREWORKS

Technical field

The present invention refers to the technical field relative to firework games.

In particular, the invention refers to an innovative support for fireworks, particularly for propulsion ones, such as volcanoes, fountains and fireworks that explode in altitude .

Background art

Fireworks of the explosive and non explosive type, which are launched into the air, have long been known.

These can include luminous fireworks such as fountains and volcanoes, as well as fireworks that explode when they reach a certain altitude. Such fireworks take off from a support base appropriately placed on the ground.

For example, patent application number PI1999A000O24 in the name of the same applicant of this patent has long been known, and describes a box-like pyrotechnic device to light fireworks in sequence.

The invention is composed of a box-like element containing inside it a lighting plan on which a support plane is placed superiorly, and on which, in turn, the fireworks are arranged. An external fuse penetrates into the box-like element and allows the lighting of the fire plan and thus the lighting of all the fireworks is triggered.

This box-like element can then be connected to other ones in sequence through an external tubular element into which the fuse passes. The box-like element includes a threaded attachment on which to connect the tubular element into which the fuse passes.

By appropriately adjusting the lengths, the diameters and the positions of the tubular element, it is possible to foresee the lighting, simultaneous or in sequence, of many box-like elements connected among them.

The box-like element is generally realized in materials such as cardboard.

However, such an invention presents various technical inconveniences.

In the first place, such a box-like element is very light and therefore not much stable. It is therefore necessary to fill it with plaster to make it heavier and render it more stable. The box, however, should undergo a shaking test in accordance with provisions CE2007/23C and such a filling material is often subject to breakages that cause the waste of the product. Plaster^' is in fact typically fragile.

The box, moreover, is not much stable and it hardly bears the effect of recoil in fireworks. This is due to the fact that the box has such dimensions as to contain exactly the support plan for the fireworks. Constructing a larger box that increases the stability is an impracticable operation since it would require the realization of a support plan for the fireworks much smaller in terms of area. In fact, this would increase in an unacceptable manner the production costs of the boxlike product itself and its realization difficulties. In this sense, the use of the filling material is preferred, although it is often a reason for the waste of the entire product once it undergoes the shaking test.

Disclosure of invention

It is therefore the aim of the present invention to provide an innovative support base (1) for fireworks (100) that solves at least in part said technical inconveniences .

In particular, it is the aim of the present invention to provide a support base for fireworks that results stable without the need for rendering it heavier.

It is also the aim of the present invention to provide a support base that is economical to be produced, allowing to easily vary the shapes of it without increasing production costs.

These and other aims are therefore obtained with the present support base (1) for fireworks (100) in accordance with claim 1.

Such a support base (1) is realized in polystyrene and comprises a receiving seat (2, 3) on which to place the fireworks (100) .

In this manner, the support base, which is selected of a greater width with respect to the fireworks that it will hold, creates a stable base. The fireworks will therefore emerge upwards from said support base 1 whose height can, for example, be selected in the order of a quarter (1/4) or a fifth (1/5) of the overall height of the fireworks applied.

Polystyrene is easily workable in different shapes and measures and allows to easily realize receiving seats for fireworks of any dimensions.

In accordance with such a solution, therefore, support bases of different shapes can be realized that adapt well to fireworks of different shapes, realizing them large enough as to guarantee a good and stable support base. In this manner, it is not necessary anymore to make the assembly heavier through the use of filling material that risks to compromise transport tests.

Advantageously, the receiving seat (2, 3) can be passing . Alternatively, the receiving seat (2, 3) can be blind.

Advantageously, the support base can have a substantially box-like shape.

This renders the realization process simpler.

Advantageously, the support base includes one or more channels (5) .

These channels are easily obtainable in polystyrene directly in the mould or with a hot wire cut method.

Advantageously, the channel (5) is in the shape of a groove that faces on the face ( 4 ) of support to the ground of the support base.

Advantageously, a pipe (6) can be included, applied into each channel (5) .

The pipe serves for the passage of the fuse.

Advantageously, the pipe (6) includes at its ends a screw thread to allow a connection in sequence between many support bases.

Advantageously, the pipe (6) can be of cardboard.

This has the advantage of being economical and easily workable.

Advantageously, a flexible pipe (7) can be included to connect a support base to another one through said pipe (6) .

A firework game is also described here, comprising a support base (1) as described and a firework game (100) arranged on the support base (1).

Last, it is also described here a selling kit of a firework game comprising:

- A containment box (10) into which the following items result arranged:

- A support base (1) as per one or more of the preceding claims from 1 to 10;

- A firework game (100) arranged on the support base

(l) ; - A cover (15) that is applied on the fireworks (100) on the part opposed to the support base (1);

- A flexible pipe (7) .

Advantageously, the cover (15) can include a containment seat (16) into which the flexible pipe results arranged .

This allows to economize spaces.

- Figures from 7 to 9 show a selling kit that comprises said support base with the fireworks and the flexible pipe 7 to connect it to other similar devices.

Description of some preferred embodiments

Figure 1 describes, in an axonometric view, a possible embodiment of the invention.

In particular, a support base 1 for fireworks is included, which is of polystyrene.

The support base can be assimilated to a full box- like element which can have any profile, as for example the generally quadrangular one portrayed in figure 1.

Figure 1 also shows a receiving seat (2, 3) obtained in the body of the support base. The receiving seat is of an appropriate shape and can be both passing and blind. The receiving seat serves to hold inside it fireworks 100.

In the specific case of figure 1 the receiving seat (2, 3) is blind but, as better described in detail below, it could be passing.

The shape of the receiving seat can therefore be any, in order to serve as support for fireworks of any shape, for example cylindrical, quadrangular or triangular .

As it is well known in the state of the art, fireworks are generally constituted of plastic or metal tubes in which the explosive material is placed and said tubes are glued and bound among them with a sheet in such a way as to form a single body, as for example shown with the cylindrical fireworks 100 of figure 5 or with those of figure 6. In that sense, it is therefore clear that the support base 1 can have receiving seats (2, 3) of different shapes according to the number of pipes and to the final shape of the fireworks themselves.

The receiving seat of the fireworks of figure 5 could be, for example, a simple cylindrical seat into which the cylinder 100 is placed. The same could be passing, in such a way that the fireworks themselves rest directly on the ground and have said support base that surrounds them like a lifebuoy, or else blind.

In any case, the support base 1 forms a. sort of lifebuoy that realizes a more stable base for the fireworks . In another example deduced from figure 6, quadrangular fireworks could be for example lodged into receiving seats of quadrangular shape.

In the specific case of figure 1, for example, the seat is formed by the clover 2 and by the external ring 3. This is so because the fireworks that it will hold are a cylindrical element whose external perimeter is annular and lodges into the ring 3, while inside it there are three tubes that will fall into the clover-like seat 2.

Figure 2 and figure 3, for more clarity, show a top view that highlights both the seat 2 and the circular seat 3 and a bottom view that shows the support surface 4 on which the support base 1 rests on the ground. In this case, the receiving seats are blind.

Going back to figure 1, it shows two channels 5 obtained in the support base and that form the grooves for the application of a tubular element into which the fuse passes .

Figure 4 shows a possible realization example in which the channels 5 are in the shape of grooves obtained exactly in correspondence of the base 4 and into which the tubular elements 6 (generally of cardboard) for the fuses are lodged, and eventually fixed with glue. As clarified below, and as anyway visible in figure 4, the pipes terminate with screw threads to allow to connect in sequence a support base 1 to another one through further flexible pipes 7 discussed below.

It is also clear that the channels 5, if the height of the support base is sufficient, can be obtained into the thickness of the base 1 itself, for example at mid- height and with a penetrating point.

Polystyrene is an easily workable material, of low cost and that allows to obtain different shapes and seats quickly. It is therefore clear that such a technology serves well to realize support bases of the most diverse shapes which result well stable and suitable for fireworks of different shapes, unlike cardboard box-like elements that are difficult to be worked.

Polystyrene can easily be custom-cut, for example with hot wire. In this manner, bases of any shape and size can be realized in a short period of time and at a low cost. The area can now be selected in such a way as to give a greater stability to the fireworks.

Alternatively, low cost moulds can be used into which polystyrene is glued and then solidified.

Figure 5 therefore shows a further example of quadrangular-shaped support base with a receiving seat for holding cylindrical fireworks (for example a fountain or a volcano) .

Figure 6 shows the connection in sequence through flexible pipes 7 provided with screw threads and that are screwed to the corresponding screw thread of the pipe 6 inserted into the support base.

The assembly phase of a firework game therefore includes the preparation of the fireworks 100 as described, combining many pipes among them. Subsequently, the fireworks are placed on the support base 1 to which they remain fixed thanks to a pre-determined degree of mechanical interference with which they are coupled.

Alternatively, or in combination, the use of glue can be foreseen. At this point, the firework game is ready for being sold and used.

To that aim, figures from 7 to 9 show a selling kit that comprises a containment box 10 into which the support base 1 described above is inserted and furnished with the fireworks 100. A superior cover 15 closes the fireworks 100 and includes a seat 16 to apply to it the flexible pipe 7.
