Definitions
- the invention relates to a grenade that can be fired with the help of a propellant charge from a tube, with an impact detonator or the like from an explosive charge. igniting tapping detonator and an axially displaceable striker with a firing pin, and with a spring-loaded adjustable slider perpendicular to the striker, which is held by a locking pin that can be displaced in the longitudinal direction of the grenade, with a primer that is acted upon by a second firing pin of the striker when fired due to the inertia and ignites a two-part pyrotechnic set, the first part of which causes the longitudinal displacement of the locking pin and thus the release of the slide, and the second part of which is a self-deceleration set which takes effect when the impact is incorrect.
- the combustion of the shorter-burning delay set releases a spacer, or melts it, which keeps the rear firing pin of the impact body pressed into a recess in the slide in a secured position, so that it is fixed against displacement.
- the slide can move, making it possible for the rear firing pin to pass through to the detonator upon impact. If this is done in such a way that the detonator is not acted upon, the self-igniting primer is ignited shortly thereafter by the longer-burning second delay set, which likewise initiates the act on the detonator through the rear firing needle.
- a pyrotechnic safety and delay relay in which an ignition chain is also interrupted by a slide containing a transmission delay charge. The displacement path is blocked until it leaves the launch tube.
- a primer is fired, which in the locked position ignites the associated transmission delay charge.
- the combustion gases of the transfer delay charge move the slide into its end position, in which the connection to the main charge has been closed.
- the projectile provided with this device has neither a detonator nor a self-dismantling.
- EP-B 48204 shows a cartridge equipped with a spring-loaded slide with a launch tube and a projectile, the slide interrupting the ignition chain being secured twice. On the one hand, its movement is prevented by an axially parallel locking pin, which releases it when fired due to the inertia, and on the other hand by the launch tube, on which a pin protruding from the slide rests until the projectile has left the launch tube.
- a transfer charge is separated from the main charge to be ignited by the slide, and a delay charge is then connected to it, the connection to the launch propellant charge being blocked by means of a locking piece which can be moved axially parallel before the launch. When fired, the breech block is moved forward under the action of the propellant gases and these ignite the now accessible delay charge.
- DE-A-33 26 683 and 34 41 show explosive fragmentation grenades with a cylindrical housing part provided at the front with a projectile hood and a bottom screw closing the filling opening of the housing on the bottom or on the firing side, which carries the adapted detonator, the interior comprising a fragment jacket 556.
- the accommodation of the ignition device in the bottom part improves the functional safety of the grenades and increases the safety of the front pipe and the ignition, since both can be controlled directly by the firing.
- the invention has now set itself the task of creating a grenade of the type mentioned, in which increased security Self-dismantling in the event of malfunctions between the tapping detonator and the striking piece
- the splintering effect in the latter case is also to be improved if the target material more or less insulates the lateral splintering effect.
- a ball lock is provided in such a way that the locking pin has a tapered section, in which a locking ball engages laterally until it is fired, the locking ball being locked by a recoil bolt which bears against a plate which can be penetrated by the firing.
- the plate can be made of aluminum or brass, for example.
- the bottom part 1 of the grenade has an impact piece bore 4 made from the inside, that is to say the side facing the housing 2, into which an impact piece 5 is inserted.
- the diameter of the striking hole 4 is then reduced to the bottom surface, and a primer 10 is inserted in this part.
- the percussion bore 4 opens into a transverse channel 20 (FIG. 7), which leads radially outwards on one side and, on the other hand, is delimited by a partition 44, which is preceded by a ring 52.
- two further holes 19, 35 are diametrically opposite one another in the bottom part hen, which also open into the transverse channel 20, the bores 35 being separated from the transverse channel 20 by the partition 44. They are preferably arranged at the same radial distance from the striking hole 4.
- a channel 23 extends in the base part 1 parallel to the transverse channel 20, in which a slide 24 exposed on the upper side is slidably arranged.
- the slide 24 is provided with side guide webs which engage in side grooves 11 of the base part 1 (Fig. 4).
- a cover on the explosive charge side in the form of an insulation board 30, against which a transfer charge 34 rests, is provided above the base part 1.
- a locking bore 16 opens radially into the bore 35 receiving the locking pin 12 from the outside.
- the locking pin 12 has two tapered sections 13, 14 in this embodiment. In the secured position, the tapered section 13 is located at the height of the radial locking bore 16, in which, under the action of a spring 18, a locking bar 17 is arranged which engages in the tapered section 13 of the locking pin 12. After screwing in the base part 1, the locking bore 16 and the transverse channel 20 are closed off from the outside by the pot carrying the insulation board 30, so that the entire detonator installation is encapsulated.
- the second tapered section 14 has a length that is greater than the reduced thickness of the slider 24 and a diameter that is smaller than the width of the longitudinal slot 25.
- the grenade is fired from the tube 36 by the propellant charge 60.
- the plate 41 and the shear pin, if provided, of the striking piece 5, which acts on the primer 10 breaks. This ignites the pyrotechnic set 21, which is contained behind the primer in the transverse channel 20 and burns radially outwards on both sides.
- Both the impact ignition chain between the striking element 5 with its ignition needle 8 and the transfer charge 34 and the self-ignition ignition chain between the primer 10, the L-shaped self-deceleration delay set 22 and the transfer charge 34 are still interrupted by the slide 24.
- the slider 24 remains in the secured position, although the locking pin 12 is moved forward, and the self-dismantling ignition chain is interrupted. Since the burning detonator 27 is highly flammable and, due to production-related circumstances, even in the secured slide position, the end of the self-deceleration delay set 22 is relatively close, the risk of an unwanted burnout in the event of the target being hit prematurely in the fore-pipe protection area by the ring 52 holding the destructible partition 51 Blind hole 54 in the slide 24 and completely eliminated by a relief channel 53. The ring 52 forms a cross-sectional constriction, so that the distance to the burning detonator 27 is increased.
