    • This invention relates to a firing launching system and method which comprises a base having a plurality of apertures. The plurality of apertures receive a plurality of mortars which, in turn, receive a plurality of Pyrotechnic projectiles which may be situated in the plurality of mortars, respectively. The Pyrotechnic projectiles may then be ignited and launched to provide a fireworks display. The base may be a one-piece molded solid construction and provided with the plurality of apertures such that at least two-thirds of each of the plurality of mortars is encased to provide support to a wall of the mortar. The base may be provided with a plurality of apertures having a common diameter for receiving a common size mortar or receiving one of a plurality of sleeves, each having the same outer diameter, but a varying inner diameter to permit the sleeve to receive a different sized mortars. In alternate embodiments, the base may be provided hollow such that it can be filled with an insulator, such as water or sand, at a launch site. In this embodiment, the base can be emptied to facilitate transporting the base to and from the pyrotechnic launch site.
    • 本发明涉及一种起火发射系统和方法,其包括具有多个孔的基座。 多个孔容纳多个迫击炮,其又分别接收可分别位于多个迫击炮中的多个烟火射弹。 然后可以点燃和发射烟火弹,以提供烟花汇演。 基座可以是单件模制固体结构并且设置有多个孔,使得多个砂浆中的每一个的至少三分之二被包围以提供对砂浆壁的支撑。 基部可以设置有多个孔,其具有用于接收共同尺寸的砂浆的共同的直径,或者接收多个套筒中的一个,每个套筒具有相同的外径,但是具有变化的内径,以允许套筒接收不同尺寸 迫击炮 在替代实施例中,基座可以设置为中空的,使得其可以在发射位置处填充有绝缘体,例如水或沙子。 在该实施例中,基座可以被排空以便于将基座运送到和从烟火发射场地运送。

    • A longitudinal launcher tube made substantially of polyurethane resin or plastic having a rear end closed by a transverse rear wall and an open front end. The invention allows a projectile to be housed in the tube and adapted to slide longitudinally inside it towards the front, to be expelled from it via the front end tube, means for defining with the tube and projectile a rear gas expansion chamber immediately to the rear of the projectile, and an impulse cartridge adapted on command to develop gas pressure in the rear chamber to cause the expulsion of the projectile via the front end of the tube. The apparatus is a pyrotechnic device for rigidly supporting fireworks such as mortar-type, rocket-type, projectile-type, and other pyrotechnic devices so that the launcher device is reusable, whereby the launcher substantially retains its integrity after each launch to minimize harm caused to persons and the environment.
    • 主要由聚氨酯树脂或塑料制成的纵向发射管,其后端由横向后壁和敞开的前端封闭。 本发明允许将射弹容纳在管中并且适于在其内部纵向地向前滑动,通过前端管从其排出,用于与管一起定出的装置,并将后气体膨胀室立即向后推 以及一个适于根据命令开发后室中的气体压力以引起射弹从管的前端排出的脉冲盒。 该装置是用于刚性地支撑烟花的烟火装置,例如砂浆型,火箭型,射弹型和其他烟火装置,使得发射装置可重复使用,由此发射器在每次发射之后基本上保持其完整性,以最小化所造成的危害 给人和环境。
