Holder for fireworks.

Overturned fireworks, including fireworks batteries, rockets and bomb tubes are a big problem. When the fireworks is overturned and set on fire, they can cause disabled personal injuries such as eye damages. Overturned fireworks, set on fire, can furthermore cause devastation of huge material values.

Alone in Denmark there has been reported 3.997 accidents, caused by fireworks on New Year's Eve from 1995/96 to 2004/05. Of these accidents Roman fireworks, fireworks batteries and bomb tubes amounted to 18%, and rockets amounted to 40%. http : //www.fyrvaerkeri .dk/static paqes/uaqstat. pdf

Because of the many and often violent accidents, caused by New Year rockets great efforts have been made in establishing holders which will secure a stable placement and firing of New Year rockets. See for example WO 03089870 Al, US 4771695 and DK 172842 Bl.

These holders, however, are dedicated to New Year's rockets and cannot be brought to usage by the holders of fireworks batteries.

From EP 1580519 a holder is known, which in a limited extent, can be used for holding fireworks batteries. The holder, which is described in this patent script, is designed as a clothes-peg with 2 jaws, where the jaws can maintain the fireworks batteries mechanical or by a spring force. But because of the lever principle the fireworks batteries can only be maintained by a very limited force and only from two directions, which is not enough for big fireworks batteries, as the biggest fireworks batteries have diameters of more than 20 centimeters. By maintaining the fireworks batteries in the one end of the jaw there is furthermore the disadvantage that a very limited stabilization is obtained in setting the fireworks batteries on fire.

US 2004217020 concerns a holder that can be used for maintenance of en predetermined size of fire works, where the fire works are kept maintained by

two jaws. The jaws are kept in place by a string, which implies that the user can tie a non-skid knot, as the powers from big fire works batteries can be very fierce. Therefore this solution is very insecure for the users. Especially if the user is under the influence of alcohol, which is not unusual for grown-ups on a New Year's Eve. The holder, which is described in the American patent script, US 2004217020, has furthermore the disadvantage that the user gets dirty fingers, if he wants to use the holder several times, as the distance from the position of the fireworks battery and to the position where the holder has to be open, is very short. The possibility for reusing this holder is furthermore made difficult by the fact that, the non-skid knot shall be tied in such a way that it is easily opened again. Many users will have difficulty in doing this in cold weather and the user has cold fingers and/or if the user is under the influence of alcohol.

Therefore it is the purpose of the present invention to provide a more stable holder for fireworks batteries that partly is very simple to use and partly can be folded together quickly in preparation for a reuse later on.

Furthermore it is the purpose of this present invention to provide a very stable launch pad, which can be reused in firing of even very huge rockets and bomb tubes, where the launch pad can be fixated by the holder according to the invention.

Beyond satisfying purposes the drawn up according to that the holder should be easy to operate and to reuse, the present invention can furthermore consider that launch pads regardless of their sizes or designs can be launched securely, when they are fasten, placed centrally in the holder. The present invention provide furthermore a fastening of bottles such as beer and wine bottles, used as launch pad for smaller fireworks, especially smaller New Year's rockets.

However, using a dedicated launch pad a very secure launch is considered even for very big rockets and bomb tubes.

The preferred embodiment of the holder for fireworks, according to the invention, is built of 2 long and 2 short bars, for example made out of flat bars, where each bar is assembled in revolving gear, in one level, together with 2 of the other bars, and where all 4 bars are buckled in one end to form the basis for a level of the 4 bars for heights between 5 and 30 centimeters. When the present invention is used for keeping the fireworks batteries in place, the invention is buckled or folded against the actual fireworks battery at which at least 3 of the bars are brought in contact with the fireworks battery, henceforth the invention is fixed mechanically in one of the 3 rotary link, which are furthest away from the fireworks battery. The mechanical fixation of the fireworks battery can profitably being provided by tightening together a bolt and a nut, where for example the nut is cast in a ergonomically shaped handle.

The preferred embodiment of the invention when the holder is joined to a dedicated launch pad, is preferably used for the launching of especially big rockets and bomb tubes, in this embodiment the dedicated launch pad is made out of a tube shaped body. At the bottom of the pipe-shaped body a number of legs can be fitted on, preferably 3 collapsible legs. At the same level as the uplifted level of the holder - between 5 and 30 centimeters from the ground - the tube shaped body has a ring-shaped body with a exterior diameter of at least 5 centimeters, fitted on.

The invention is more closely described below with references to the drawing.

As it appears from the figures 1, 2 and 3 the item, mainly a fireworks battery or for example a launch pad for big rockets _/ will be placed in the middle af the rack 1 and fixated by the influence of at least 3 central forces pi, p2, p3 and/or p4 on the same level, when basis A and basis B are being moved away from basis C and basis D. When the item is kept in this position by the bars, the bars are kept in this position by fitting on one of the 3 assemblings Ll, L2 or L3, the one which furthest away from the item. In fitting on for example assembling L3 it is profitably to be able to use a ergonomically shaped handle H, for ensuring fixation of the link.

To ensure that the strong pressure that is directed towards the fireworks batteries does not cause a perforation of the fireworks batteries, the 2 short bars at the ends that can come in contact with the fireworks batteries can be buckled upwards.

After use the handle, H, is loosened, after this A and B are being moved towards C and D, after which the item can be lifted up or the holder can be lifted up over the item. Subsequently the holder can be folded completely, as the right bar a' is shorter than the left short bar b' to allow the buckled-up end of Ol can pass by the buckled-up end of 02.

It seems obvious to place for example a plast tube centrally in the holder, and then use the plast tube as a launch pad for especially big rockets and bomb tubes. By fixation of the plast tube, the holder, however, should be squeezed very much before the plastic tube is fixated. This has the unfortunate consequence that only a very small support and therefore a very small stabilization of the plast tube, as the supporting area becomes very slim, which results in the plastic tube to overturn easily, together with eventually a big, New Year's rocket, which has been set on fire. Therefore it is pecessary to use a plast tube with a very big diameter or to use a dedicated launch pad 27, when launching big rockets and bomb tubes, when the rack, according to the

invention, should secure the stabilization of the tube, which is used as launch pad.

One of the conditions for a big stability of a dedicated launch pad 27 will therefore be a relative big diameter on the same level as where the central powers pi, p2, p3 and p4 from holder 1 can tribute to the intentional fixation of the launch pad. The big diameter of the launch pad can for example be achieved by letting the tube-formed item having a ring-formed item with a relative big diameter 28 fitted on.

The launch pad does not achieve a sufficient stability, if only the ring-formed item is fixated. Furthermore it is essential that the launch pad itself has a big supportive area. A big supportive area can for example be achieved by fitting on mainly 3 collapsible legs 29 near the bottom of the launch pad 27.

The holder 1 can be produced of metal or plastic. When the holder 1 is made of plastic, it can profitably be produced of plastic containing fire-resistant or coated with a fire-resistant material, furthermore it will be profitable to increase the weight of the plastic holder 1 by mixing the plastic with either sand or glass. In limiting the wear on the moulds grain of sand and/or grain of glass for production should be coated with a kind of plastic with a melting temperature, which is higher than the plastic mass used in the production. As an alternative or as a supplement for increasing the weight, it will be profitable to produce the holder of plastic tube containing one or more channels, which can be filled with a ballast-material, including grain of sand and grain of glass.
