Definitions

  • the invention relates to a signaling means, in particular a Signal rocket.
  • Pyrotechnic signaling devices are used primarily in the air and Seafaring, third parties on acute emergencies and impending To draw attention to dangerous situations.
  • the a signal rocket that is usually fired from the hand and on the other signal cartridges, which consist of a suitable signal gun are fired, used.
  • Such Signaling devices are also used as pyrotechnic lighting devices for airport apron lighting or lighting for search and rescue operations at night.
  • the signal is fired from an outer tube, in where the signal is housed.
  • the signal occurs after the Ignite from the outer tube, by one with one detachable closure provided end face of the outer tube, which is removed from the signal.
  • the invention is a practical training of Closure on the upper face of the outer tube, which in the must meet two essential requirements.
  • the closure of the mechanical stresses of the Signal rocket, especially a fall on the top face, withstand, without the already ignited Signal can slip out of the outer tube.
  • the signal with the lowest possible Step out the resistance from the front of the outer tube can, so the closure can be easily blasted off so that the Recoil is as low as possible.
  • Signal means are known in which a closure of the upper end of the outer tube assigned to the signal through one or more discs.
  • a closure of the upper end of the outer tube assigned to the signal through one or more discs.
  • the EP 0 277 275 B1 discloses a generic signal rocket, at of several items, namely a cover in Connection with a curved collecting disk, a functional closure of the top of the Form outer tube. This configuration corresponds to the from a mechanical and ignition point of view Signaling requirements, but it is in production-technically unfavorable. So trained Signaling devices can only be installed with great effort.
  • a firework rocket is known from DE 39 02 381 A1 has an envelope (missile body), the lower and the upper part by means of a predetermined breaking seam similar to a bellows are connected.
  • the wall thickness of the envelope is everywhere about the same, even in the area of bellows-like Predetermined breaking seam. This leads to the blasting of the Head of the envelope from the rest (lower) part of it is not relieved, which is therefore not the case with fireworks rockets is required because this is unlike signal rockets not be shot out of your hand and thereby hit it on one low recoil doesn't arrive at all.
  • the invention is based on the object To create signaling means that are reliable and functional closure that has a simple Manufacturing guaranteed.
  • the signaling device has the features of claim 1.
  • the manufacture of the Signal means simplified. In particular, assembly is not required the previously separate cover.
  • the constriction causes force on the cover opposite to the direction of the rocket launch, e.g. at a fall on the locked face of the signal rocket, that the coverage is limited in scope elastic region is deformed. Removing the cover from the Outer tube and the associated slipping out of the signal from the outer tube is prevented.
  • a predetermined breaking point is assigned to the cover by means of a signal.
  • the predetermined breaking point ensures when the Signal rocket using the signal as possible low resistance.
  • the cover can be easily removed from the outer tube loosen or blow off, and thereby the recoil at Reduce firing of the signaling agent.
  • FIG. 1 shows a parachute signal rocket 10 Signaling means.
  • An elongated cylindrical outer tube 11 of the parachute missile 10 has two each other opposite end faces 12, 13.
  • the lower end face 13 has an opening 14.
  • the opening 14 is through a Bottom 15 releasably closed to the outer tube 11, which is a manually operated trigger 16 for the ignition assigned.
  • Towards the rocket launch (arrow 17) seen above the floor 15 is a propellant 18 and a signal above it, namely a star set 19, with one above it folded parachute 20.
  • the top face 12 of the outer tube 11 is a trained according to the invention Closure 21 assigned. For the rest, the propellant 18 and the star set 19 still trained in a conventional manner Cheers, delay rates and intermediate rates assigned, which are not described here.
  • a closure 29 according to a first embodiment of the Invention consists of a cover 30 with a wall 33 of the outer tube 11 is formed in one piece (FIG. 3).
  • the Cover 30 consists of two sections, namely one lower, cylindrical section 31 and an upper, conical section 32.
  • constriction 34 is assigned in the lower, cylindrical section 31 is the cover 30 a constriction 34 is assigned.
  • the constriction 34 is as circumferential, outside of a wall 35 of the lower section 31 outgoing, groove formed.
  • the depth of the neck 34 is several times greater than the thickness of the wall 33 of the Outer tube 11.
  • the width the constriction 34 is dimensioned such that when a force is applied opposite to the direction of the missile launch the deformation of the cover 30 is always in the elastic range remains.
  • the constriction 34 is small Distance to a bottom wall 36 of the cover 30 is arranged. This creates between in a transition region 37 Cover 30 and wall 33 a predetermined breaking point 38.
  • the predetermined breaking point 38 or the distance of the constriction 34 from the Bottom wall 36 is less than the thickness of the wall 33, and in such a way that when the parachute signal rocket 10 the closure 29 can be easily blown off.
  • the closure 21 consists of a cover 49 which is integral with a wall 50 of the Outer tube 11 is formed.
  • the cover 49 consists of a lower, cylindrical section 51 and an upper, tapered section 52.
  • the lower section 51 are one Constriction 53 and a notch 54 assigned.
  • the constriction 53 is from a wall 55 of the cover 49 starting as a circumferential groove.
  • the training and The constriction 53 is dimensioned analogously to the constriction 34 of FIG. 3.
  • the notch 54 is based on a Bottom wall 56 of the cover 49 an edge region 57 of the same assigned.
  • the notch 54 is V-shaped in cross section formed, with one leg of the notch 54 through the Wall 50 is formed.
  • the notch 54 is therefore in the Transitional area (edge area 57) between cover 49 and Wall 50 arranged.
  • the depth of the notch 54 is such dimension that in the transition area a defined predetermined breaking point 58 arises.
  • the notch 54 has one Opening angle of 10 ° - 50 °, preferably 30 °. The opening angle from 30 ° has been considered a recoil-free Detonation of the closure 21 as particularly favorable proven.
  • Fig. 5 shows the operation of the designed according to the invention 4, in the event of a force opposite to the direction (arrow 17) of the missile launch (for example, by dropping the parachute rocket 10 on the closure 21).
  • a force opposite to the direction (arrow 17) of the missile launch for example, by dropping the parachute rocket 10 on the closure 21.
  • the Deformation of the cover 49 is determined by the width of the Constriction 53 limited.
  • At maximum deformation of the Cover 49 is in the area of wall 50 of outer tube 11 the constriction 53 compressed so that sections opposite walls 59, 60 of the constriction 53 one on top of the other lie. Forms outside the area of the wall 50 the constriction 53 a cavity 61.
  • constriction 53 is a the wall 50 and the end of the groove limited circular ring Cover 49 deliberately deformed.
  • the depth of the constriction 53 or groove determines the width of the annulus. Combined with the width of the constriction 53 ensures the depth of the same, that the deformation of the cover 49 or the annulus is limited and always remains in the elastic range, so that the predetermined breaking point 58 does not break.
  • the closure 62 consists of a cover 63 which with a Wall 64 of the outer tube is connected in one piece.
  • the Cover 63 consists of a lower, cylindrical section 65 and an upper, conical section 66. Analogous to that 4 are the lower portion 65 a Constriction 67 and a notch 68 assigned. in the 4 is the difference from the exemplary embodiment according to FIG Constriction 67 formed in a special way. Starting from a wall 69 of the cover 63 is the constriction 67 as circumferential groove formed. The depth of the constriction is 67 a multiple, in particular a double, larger than the thickness of the wall 64 of the outer tube.
  • the width of the Constriction is due to technical manufacturing conditions formed thicker than in the exemplary embodiment according to FIG. 4. So that the constriction 67, however, its functionality Limitation of deformation of the cover 63 are the same Assigned to webs 70.
