Definitions
- the invention relates to a pyrotechnic charge in a pipe the preamble of claim 1.
- DE 26 44 230 A1 discloses a practice hand grenade with an ignition delay, in which a pyrotechnic charge u. a. generated a bang. This is this charge is placed in a tube inside the grenade. The pipe closes with one, when the pyrotechnic charge is ignited by the building gas pressure tearing ground. It cannot be ruled out that large parts of the ground fly away with high kinetic energy, which according to the applicable regulations is not permitted.
- the object of the invention is therefore a closure for a pyrotechnic charge to create, in which parts fly away but these have a very low mass have, so that the energy transmitted through these parts far below a permissible value remain.
- FIG. 1 shows a hand grenade in longitudinal section and FIG. 2 shows an enlarged one drawn section of a charge tube according to FIG. 1.
- a practice hand grenade 1 shown in dash-dot lines has a central charge tube 3 with primer 5, a time-delayed set 7 and a bang charge 9 on.
- the charge tube 3 closes with its free end face 11 approximately with the lower one Face 13 of the practice grenade 1.
- a bore 15 takes the bang charge 9 on.
- the charge tube 3 has a conical seat 17 for a ball 18 from a light, foamed styrene and a recess 19 for one disk-shaped or lid-shaped silicone layer 21 consisting of a vulcanizable Silicone rubber.
- This is crater-shaped 27 and in relation to the ball 18 with respect to the conical seat 17 conical 28.
- the ball 18 is seated in the conical seat 17 with a slight preload, with about 50% of the Ball surface is glued to the silicone layer 21.
- the silicone layer 21 is in turn over the surface of the recess 19 and part of the conical seat 17 glued to the charge tube 3.
- a very thin, membrane-shaped layer 31 of the silicone layer 21 enables the Ball 18 exits charge tube 3.
- the diameter 23 of the recess 19 is larger than the diameter 25 of the Ball 18. Because of this and through the conical seat 17, 28 or the edge 29 there is a Large adhesive surface of the silicone layer 21 on the charge tube 3 and on the ball 18 before. In the event of hard impacts in the axial direction of the charge tube 3, this ensures that the bang charge 9 applied to the ball 18 by the ball 18 and the silicone layer 21 existing closure 30 an opening 33 of the charge tube 3 closes securely.
- the time-delayed set 7 burns and ignites the bang charge 9.
- the gas pressure of the bang charge 9 drives the ball 18 out of it Tapered seat 17.
- the silicon layer 21 increases in the area of the layer 31 deformed until the ball 18, the increasingly thin silicon layer 21, 31st pierces.
- the silicone layer 21, 31 therefore remains on the charge tube 3 while the ball 18 due to its very low mass and due to the large air resistance quickly falls to the ground. The given conditions for the kinetic Energy and flying distance of flying parts are not reached, so that the safety conditions are met.

dadurch gekennzeichnet,
daß das Rohr (3) eine Ausnehmung (19) zur Aufnahme der etwa scheibenförmigen Silikonschicht (21) aufweist und der Durchmesser (23) der Ausnehmung (19) größer ist als die Kugel (18). - Pyrotechnische Ladung nach Anspruch 1,
dadurch gekennzeichnet,
daß die Silikonschicht (21) aus einem vulkanisierbarem Silikonkautschuk besteht. - Pyrotechnische Ladung nach Anspruch 1,
dadurch gekennzeichnet,
