Abstract

Single pipe for pyrotechnics, of the type comprising a tubular body housing a bullet or meteor generating a light and chromatic burst at high altitude, characterized by comprising, inside the tubular body (1), integral means (10) for the temporary fastening of the bullet (3) prior to its firing, advantageously constituted by a protrusion of internal diameter, necessary and sufficient for said temporary retention, without hindering in its moment the exit of the bullet.

Description

Monotiro tube for pyrotechnics.

Object of the invention

This Utility Model. refers to a monotiro tube for pyrotechnics.

It is a device of the type called usually a candle that produces a light and colored burst in its high rise.

Field of the Invention

It is the manufacture of pyrotechnic articles for the generation of light and color effects in the castles of fireworks and the like.

Background of the invention

Pyrotechnic devices of the type are known called candela, which shoots at high altitude a bullet or meteor with light and color effects, which consist of a body tubular bearing of the meteor inside in order to its launching.

The meteor or bullet, usually in the form of cylindrical tablet, remains held inside the body  tubular support, until the moment of its firing, by a temporary fastener element, which usually consists of a washer or a cardboard, plastic or similar disk.

When the shot occurs, that element ends its retaining function of the pellet or bullet and it follows, falling to the ground

In a fireworks castle, where shoot a lot of this kind of devices (monotiros), is therefore generated as a byproduct of releases, a large number of washers or fastener discs. This means a true pollution of the environment, which requires a consequent cleaning of the floor for the elimination of those objects.

It was desirable to have a monotiro pyrotechnic whose launch does not produce the generation of polluting by-products of the environment, specifically of the land launch and its surroundings.

Brief Description of the Invention

To satisfy the aforementioned purpose, it has been designed a monotiro or candela whose bearing tubular body means means for temporarily holding the bullet to the shot time, means not consisting of an applied part and therefore separable and remnant, but formants of one's own tubular body, not generating waste after launch.

The means in question advantageously consist in one or more internal projections in the tubular support body Of the device.

To facilitate the explanation, the present description of some drawings in which it has been represented,  by way of illustrative and non-limiting example, a case of realization of a monotiro tube for pyrotechnics, according to principles of the claims.

Brief description of the drawings

Figure 1 is an exterior perspective view of a monotiro tube of the class described.

Figure 2 is a meridian section view of the  Monotiro himself at his disposal for the shot.

Detailed description of the invention

The designated elements with numbers in the Drawings correspond to the parts indicated below.

The device consists of a tubular body 1 of  support, open base, whose interior 2 houses, in its part middle and lower, the means of lifting the bullet or meteor 3, consisting of a cylindrical pyrotechnic tablet 4, of a appropriate composition.

The bullet or meteor drive 3 is effected by means of a load 5 of granular powder, contained in a space conical 6 formed in the inner and lower part of body 1, prolonged in a narrow central cylindrical zone 7 occupied by a electric igniter 8 and in which the end of a wick concurs 9 intended to turn on the device.

Characteristic of the present invention is the existence, inside the tubular body 1, of means temporarily retainers of the bullet or meteor 3. Such means they may consist of an annular internal projection 10, in a group of stubs or prominences or the like.

This avoids the need to apply parts additional clamping whose permanence after the firing of the device produces the aforementioned contamination of the environment ambient.

The conical shape of the lower space 6 which allows to reduce to a minimum the amount of Gunpowder 5 and keep it concentrated. This achieves a regularity in the force produced in the firing of the tube and a uniformity in height reached by the different tubes monotiro of a set of them.

Claims (4)

1. Monotiro tube for pyrotechnics, of the type comprising a tubular body that houses a bullet or meteor generating a high-rise light and chromatic burst, characterized by comprising, inside the tubular body (1), integral means (10) for the temporary clamping of the bullet (3) prior to its firing, advantageously constituted by a prominence of internal diameter, necessary and sufficient for said temporary retention, without hindering the exit of the bullet at the time. 2. Monotiro tube for pyrotechnics, according to claim 1, characterized in that the clamping means (10) consist of an internal projection in the form of an annular nerve. 3. Monotiro tube for pyrotechnics, according to claim 1, characterized in that the fastening means (10) consist of a plurality of regularly distributed radial lugs. 4. Monotiro tube for pyrotechnics, according to claim 1, characterized in that it comprises in its internal lower part a space (6) of conical housing for the load (5) of granular discharge powder, which is thus concentrated in a reduced volume and causes a regularity in the impulse of the bullet and in the height reached by the latter.
