PYROTECHNIC CARRIER STRUCTURE

Abstract

The invention relates to a pyrotechnic carrier structure made from profiles (1) that can be interconnected on the edges thereof and with relative rotational freedom in order to form a firing base (20), to be horizontally arranged on the ground or warped for the arched arrangement thereof on support elements (12) formed by pairs of housings (13 and 14, 15 and 16, 17 and 18). Furthermore, the longitudinal movement of the profiles is avoided.

PREFERRED EMBODIMENT OF THE INVENTION

[0024] In the embodiment described and referencing the drawings, a pyrotechnic carrier structure is comprised by profiles 1 arranged so that they can be connected one next to the other as shown on FIG. 1 in order to form a carrier base 20 for the mortars 21 containing the fireworks at the moment they are fired. Referencing FIG. 1, each profile 1 has a rail 2 running along its length configured to receive and retain the base of the mortars, and this rail is centred longitudinally on the firing side and in a part 3 of the profile 1, whereas the side of the profile 1 that rests on or faces the ground comprises reinforcing ribs 4 to withstand the effects of firing the pyrotechnic mortars. The first connecting member 7 extends along the length of a first longitudinal edge 5 of the part 3 of each profile 1; it is completely hollow and is longitudinally open all along the length thereof by means of an axial slot 9. The second longitudinal edge 6 of said part 3 of each profile 1 extends longitudinally by means of the second connecting member 8, which can be seen in the example as comprising a section that corresponds with and is adjusted to the first connecting member 7, though that is also smaller.

[0025] As can be easily observed, FIG. 2 shows more clearly the rotational freedom determined by the angle (a) shown by two profiles 1 once they have been connected together after inserting and sliding the second connecting member 8 of a profile 1 in the corresponding first connecting member 7 of an adjacent profile 1, and after being rotated.

[0026] FIG. 3 shows more clearly the connection between two horizontally arranged profiles 1, and it also displays the surface recesses 10 made transversally on the supporting side of each of the profiles 1, which in the example extend to the first connecting number 7 and equally extend to the reinforcing ribs 4 of each of the profiles 1. The surface recesses 10 collaborate with the central longitudinal tabs in the searing pins 11, which are connected and can be dismounted in both profiles 1, and inserted either by sliding or snap-fitting them between the reinforcing ribs 4 next to the recesses 10, so that the tabs of the searing pins 11 fit on the recesses 10, typically in order to prevent the longitudinal movement between both profiles 1.

[0027] An example of a support element 12 of the pyrotechnic carrier structure 20 of the mortars 21 is shown on FIG. 4 independent from the pyrotechnic carrier structure, which shows the configuration and arrangement of the housings 13, 15, 17 and 14, 16, 18, in addition to the inclination of their respective geometric axes (b, c, d) in relation to the slots 19.

[0028] The pyrotechnic carrier structure comprises a base 20 comprised of a plurality of profiles 1 as shown on FIG. 5, though comprising a larger number of profiles on FIG. 6. Referencing the drawings, the base 20, which is formed by profiles 1 connected together after their respective second connecting members 8 have been inserted and slid in the corresponding first connecting members 7 of the adjacent profiles, is shown warped and mounted after the outer end parts thereof have been inserted in the pair of housings 15 and 16, which are longitudinally separated in the support elements 12, or vice versa, as shown on FIG. 5; or in the pair of housings 13 and 14 as shown on FIG. 6. In the example provided, the first lateral part of the base 20 is formed by the first longitudinal edge 5 and the first connecting member 7 of an outer profile in one of the sides of the base 20, and the second lateral part is formed by the second longitudinal edge 6 and the second connecting member 8 of the outer profile in the opposite side of the base 20. Optionally and although it has not been shown in the drawings, the base 20 of the pyrotechnic carrier structure could be horizontally arranged on a support surface, without having to use the support elements 12.

[0029] As shown in the examples of the structures shown on FIGS. 5 and 6, each one of the housings 13, 14, 15, 16, 17 and 18 extends downwards towards the support elements 12 from an upper slot 19 of a narrow width that is, however, wider than the thickness of the part 3 of the profiles 1. It can also be observed that the housings of each pair of housings 13 and 14, 15 and 16, 17 and 18 in the support elements 12 are separated from each other. The pairs of housings are shown contained in each other, and the inclination of the geometric axes of the housings 13, 15 and 17 are shown in opposition to the orientation of the housings 14, 16 and 18. Each pair of housings is shown with a different orientation that increases and tends to the vertical line towards the outer sides of the support elements 12. Likewise, it can be observed that the design of each housing is adapted for inserting and sliding the respective general sections of the outer lateral parts, 5 and 7, 6 and 8 respectively, of the mortar carrier base 20, so that each of the profiles 1 that form the base 20 are oriented at a predetermined and different angle in relation to each adjacent profile 1, and the lines of mortar tubes, which are shown on FIG. 6 by means of the mortar 21 that is further ahead, are oriented normal to the corresponding orientation of the profiles 1, with (e) describing the angular distance between them.

[0030] The invention has been described pursuant to the shown embodiments. It becomes obvious that it is possible to contribute modifying details and/or replace specific elements or devices for other equivalent ones or add supplementary devices of the known type without abandoning the scope of the invention.
