Definitions

  • the present invention relates to a rifle grenade with a launcher, which can be placed on a rifle, the grenade being accelerated and initiated by the muzzle pressure of a rifle ammunition, an axially movable projectile trap being provided in the launcher, which stores the ignition energy for the grenade and releases in the presence of sufficient gas pressure.
  • Rifle grenades attached to infantry rifles according to the preamble of claim 1 have been known for many years. These are over-caliber explosive projectiles, which consist of a jacket, the explosive charge and a detonator. These are firmly connected to a tubular launching device, which comprises the projectile trap and a tail unit for flight stabilization.
  • the effect in the target should not be impaired by parts of the launcher and / or guide surfaces remaining on the grenade.
  • the Grenades have tactical advantages, such as those desired in house-to-house combat.
  • the launcher has a mechanical lock which unlocks through the muzzle pressure generated when the projectile is fired and releases the grenade.
  • the complete separation of the grenade from the launcher gives significantly better kinetic properties; the effect of the grenade in the target is also better, especially when using a splinter jacket, or it can also achieve targets that cannot be assigned with rocket-like grenades.
  • a piece of pipe also called a garnet neck or grenade sleeve, protrudes from the rifle grenade at the rear, which receives at least part of an ignition chain and has a collar-shaped flange, that the piece of pipe is conical at the end, that the firing device has at least two mutually opposite claws , which reach over the flange and hold the pipe section in a form-fitting manner and that these claws can be disengaged by the axial movement of a driving piston with a projectile trap, as a result of which the grenade on its ballistic path separates from the launcher.
  • the claws mentioned in claim 2 are pivoted out by the forces resulting when the rifle grenade is fired, so that they release the collar-shaped flange of the grenade and this is exposed to an unobstructed ballistic flight.
  • the spherical shape, claim 3, proves to be particularly advantageous since it can be used to achieve a high degree of accuracy. It is unaffected by weather conditions; the non-wing stabilized grenade will hit upon impact hard obstacles distracted by the type of elastic impact. This property can be used in tactical use (eg in house warfare); a new doctrine of use for rifle grenades can be created.
  • the effect at the target is unaffected by the tail unit and accordingly less dependent on the angle of impact of the grenade.
  • the hand grenade body mentioned in claim 4 is particularly economical and has already been tried and tested many times. Warehousing and logistics are significantly simplified by a grenade that is suitable for both manual throwing and firing a rifle.
  • the embodiment according to claim 5 is particularly safe to use and simple to manufacture.
  • the conical surface according to claim 6 ensures a safe opening of the claws when firing.
  • the transmission element according to claim 11 is particularly space-saving and economical.
  • Fig. 1, 1 designates a rifle grenade, which is essentially a notoriously known, spherical hand grenade.
  • the grenade 1 is supported by a grenade holder 2 formed by wings and held positively by means of claws 4.
  • the claws 4 are arranged at the end on claw levers 3 and have cams 5 in their central region, which protrude into the interior of a support tube 7.
  • the claw levers 3 - a total of four - are held resiliently in a base ring 6.
  • the base ring 6 is in turn mounted on the support tube 7.
  • the end part of the support tube 7 has a taper 8.
  • the grenade shown with the launcher is stored and transported in the form shown in FIG. 1. It is used by slipping the support tube 7 onto a conventional rifle 60, FIG. 2.
  • the support tube 7 encloses the muzzle brake 62 and the barrel 61 in a manner known per se; it is non-positively fixed on the shooting cup, not shown here for drawing reasons, by a ring spring.
  • the ready-to-fire device FIG. 2, shows details from FIG. 1; the grenade 1 has a two-part jacket 100, 100 ', in which an explosive charge 101 is cast.
  • an ignition chain 102-104 consisting of a pyrotechnic delay set, an ignition charge, and a detonator projects in the form of a tubular detonator into the explosive charge 101.
  • the grenade 1 is supplemented by a short pipe section 10 with flange 11 and a conical surface 12, which pipe section 10 is glued to the jacket 100 by a bead 13.
  • claws 4 which are designed to be disengageable via a claw lever 3 and four cams 5, grip over the flange 11.
  • the claw levers 3 are resiliently arranged in a base ring 6, which rests on the pipe section 10 in a non-positive manner and is positioned on the taper 8 at its lower end.
  • the unlocking piston 18 has a cylindrical bore with an inner cone 20, in which a uniformly shaped driving piston 21 is slidably inserted, which also has a damping ring 21 '.
  • the driving piston 21 is sealed against the inside diameter of the support tube 7 by a gas-tight ring seal 22; in its central area it has a projectile trap 23 which is constructed in a manner known per se as a "sandwich" and acts as a shock absorber.
  • An additional clamping plate 24 prevents the driving piston 21 from sliding out.
  • FIG. 3 shows the device described above in its firing phase, the firing direction being designated A.
  • a conventional projectile 63 with a steel jacket is caught in the projectile trap 23 of the driving piston 21, during which is accelerated by the high gas pressure generated by the ammunition in the order of 1000 bar.
  • the driving piston 21 penetrates into the unlocking piston 18; the pulse is damped by the elastic damping ring 21 'and the damping space 21''between the components, which forms an air cushion.
  • the further impulse transmission now takes place via the extension 31 'of the engagement shaft to the safety element 17 which triggers the ignition if the acceleration is sufficient.
  • unlocking piston 18 presses the four cams 5 outward on its axial path, so that the claws 4 which extend over the flange 11 swing out and release the grenade with its detonator 14 which acts in a delayed manner.
  • the spring 15 is used here for safe separation.
  • the device is simply put on the rifle 60 and sufficiently secured on the shooting cup for the necessary manipulation of the shooter.
  • the high gas pressure generated by the ammunition accordingly accelerates the entire device, so that the support tube 7 is also thrown at a distance of approximately 30 m from the muzzle of the rifle 60.
  • the free-flying grenade 1 can in turn, with a weight of 465 g, reach shooting distances of over 130 m; due to its pyrotechnic delay, it only explodes at the target.
  • the security element 17, which is known per se in its physical function, but has been specifically adapted to the requirements of the present launching device.
  • the preferably used security element downstream of the grenade 1 has a cylindrical shape from which the engagement shaft 31 protrudes.
  • the engagement shaft 31 receives a mechanical pulse J, which acts on an ignition pin 33 mounted in a locking shaft 32.
  • the ignition pin 33 is mounted in an ignition channel 33 'and has an ignition tip 35 which is struck on a spherical locking element 57 by an ignition pin spring 34.
  • the locking element 57 is in turn inserted and stored in a cylindrical transverse bore 57 '.
  • a mass lock 52-56 Arranged parallel to the ignition channel 33 ' is a mass lock 52-56, which consists of a guide shaft 52, a bush with a locking flange 53 and a locking shaft 54 with an annular groove 55. The entire sleeve is pressed upwards by a locking spring 56 against a spacer ring 52 '; the guide shaft 52 is supported on both sides in the housing parts 41.
  • the two-part housing 41 encloses a guide block 40; these parts accommodate the mechanical components.
  • a slide 36 with a slide spring 39 is located in the upper housing part 41.
  • a guide surface 42 ′ can be seen on the slide 36, which is partially enclosed by the locking flange 53.
  • the ignition channel 33 ' in the slide 36, there is a pinhole 43 and above the slide another pinhole 43' in the housing 41.
  • FIG. 4 is an illustration of the sectional planes A - C - - A.
  • 5 is an illustration of half the section plane C - C.
  • the firing pin formed by the elements 31-35 is also half visible.
  • the spherical transmission element 51 which rests on the one hand on the locking shaft 32 and on the other hand on an unlocking cone 49.
  • the unlocking cone 49 merges into a retaining shaft 50 and an unlocking shaft 48, which in turn is limited by a stop flange 47.
  • a locking pin 44 is transferred into a locking bolt 46 which opens into the stop flange 47.
  • the slider 36 underneath has recesses 38, 38 'on the end face; the locking pin 44 rests on the recess 38, so that the spring-loaded slide 36 cannot move any further, it is locked.
  • the spiral spring 39 arranged on the left side is provided with an arrow which indicates the direction of movement of the slide 36.
  • a central mounting hole 30 is used to insert the locking element 57, Fig. 4; Concentric to this, the ignition tip 35 below is indicated.
  • a cylindrical anti-rotation device 58 is located in a recess 58 'and is used for simple assembly of the entire device in an ammunition body or in a corresponding tubular receiving part.
  • the device according to FIG. 7 a represents the secured state before a pulse J hits the engagement shaft 31.
  • the slide 36 loaded by the spring 39 is blocked by the left-hand mass lock 44-50 and at the same time by the right-hand side drawn mass lock 52-56.
  • the ignition element 37, as well as the pinhole 43 in the slide 36, have moved laterally out of the effective range of the ignition tip 35.
  • the firing pin spring 34 is minimally tensioned and lies against the conical firing tip 35.
  • the two mass locks 44-50 and 52-56 are extended to their end positions.
  • the slide spring 39 pushes the slide 36 to the right; at the same time, the spherical locking element 57 also deviates to the right and slides into the annular groove 55, so that the ignition tip 35, driven by the spring 34, strikes the ignition element 37 and initiates it.
  • the pinhole 43 is in this slide position in congruence with a pinhole 43 '(not shown here) in the housing 41.
  • the ignition chain of the rifle grenade behind it can be detonated.
  • the safety element is a so-called safety & arm device which can store the ignition energy and, as described, acts as a double blocking element and corresponds to the usual safety regulations.
  • the spherical grenade 1 is known as such as a hand grenade (HG 85: brochure, undated, "The hand grenade collection", Swiss Federal Ammunition Factory, CH-6460 Altdorf); but without the usual safety and release mechanism.
  • FIGS. 8a, 8b again shows the simple structure of the subject of the invention with its most essential functional elements, based on its assembly.
  • the grenade holder 2 is designed as a tube piece and is thermally shrunk onto the upper part of the support tube 7.
  • the claw levers 3, Fig. 8b are now spread apart and pushed onto the support tube 7, Fig. 8a, until the end of the taper 8.
  • the slot-like grooves are in the support tube 7 25 in which the cams 5 engage or reach through.
  • the unlocking piston 18 is then pushed into the recess 28, as is the driving piston 21 - with its seal (not shown) - and the whole is fixed by a clamping plate 24 known per se.
  • the ammunition is taken from the usual hand grenade (Swiss Army HG 85); only the pipe section 10 shown here is specific to the invention; the hand grenade detonator is designed without its primary detonator (firing pin detonator).
  • the preferred embodiment described above has excellent ballistic properties in practical testing.
  • the rifle grenade can also be used tactically like a billiard ball; Targeted ricochets can also hit hidden targets. With a suitable temperature - choice of the pyrotechnic delay fuse - the grenade can also be rolled into otherwise unreachable targets.
  • separation points between the grenade and the launcher can also be realized in the manner of collets, as are known from their use in clamping machine tools and have proven themselves there.
  • a separation of the launcher and grenade is also conceivable through the targeted use of predetermined breaking points in the area of the neck of the grenade.
