"Provision made for rocket bombs of sequential color and its mould".Numerous pyrotechnic performances are performed every day in Brazil, but the companies that run generally require well-trained professionals.This factor has been the cause of various accidents.Many of them are related to the tools of shot, which are metal devices.Wood or cardboard (the latter when disposable) capable of holding the mortar in the desired position (vertical or inclined).Providing such security that cannot turn during the show (which could cause uncontrolled releases of horizontal, even against the public).There is a great demand on the market of fire pumps disposable tools with already loaded and the wicks placed and remain upright without support. There are various models available.Among them, it is very popular, the rocket bombs of color sequential, known as giru00e2ndola, which consists of 6, 9, 12 or more mortars, insured in the foot by a base and a platform.Both consist of a box or liner of corrugated cardboard.The conventional model of giru00e2ndola has the following drawbacks: it is common for the cardboard of the platform is set in contact with the fuse lit before all the mortars of giru00e2ndola are COnsumidos, a situation that can lead to unpredictable results. To fit the mortars, the bases and platforms are compatible with the diameter of holes.This configuration, which theoretically is appropriate, by the fact that in practice vary the external diameters of the tubes of the mortars.Since there is a lack of standardization among the manufacturers of domestic fires.Thus, or the tube is loose and fit with uncertainty or is necessary for placing a forced entry, bursting the cardboard, which can compromise the mechanical stability of the assembly.This provision made for giru00e2ndolas aims to eliminate these drawbacks.With less possibility of fire and allowing the fitting of mortar tubes with several diameters.
