Description

Litter grenade with two mutually movable parts. The invention concerns a grenade with two mutually movable parts. Of known Throw grenades of this type differ from the present one in that (let the inner one Part that contains the explosive charge, so movably arranged in your outer part is that due to the centrifugal force occurring when the grenade is hurled Overcoming a blockage ignites a timer.

The detonator can be of any type. Impact detonators can also be used, Use fire igniters, fuses, etc.

Since the moment is the most favorable moment for blowing up the grenade is where it hits the target. so first of all there is an opener for the ignition into consideration.

But now it can happen that for some reason the percussion fuse fails. The grenade then constitutes a constant danger for your own troops in advance, since in your case it acts as a mine, it is therefore expedient to provide a pulp fuse next to the impact fuse, which reliably secures the detonation.

Special protection for the thrower offers the fact that for the release of the percussion detonator inhibitions of any kind, such as a burnable support set, a rotatable screw spindle o. The like. Are attached, the unlocking of the Only let the percussion fuse actually occur when all parts of the projectile have assumed the same speed in flight, and only on impact the The speed limit required for bursting occurs. With all modes of action the hand grenade is in relative motion.

Throwing this grenade is as convenient and easy as it gets at all possible, since all preparatory steps, even pulling it off, are omitted, and the thrower for the throw even after removing the safety device (linch pin) can wait for a favorable moment.

The relative movement between the parts of the grenade when the grenade is thrown is used: a) to ignite the fuel, b) to unlock the fuse of the percussion fuse, c) to activate the hemilititi device.

A grenade according to the present l # ', rfiti (liLiiig is in one embodiment with igniter shown in Fig. i.

The pot of the hand grenade is divided into an inner part a and an outer part 17 for the purpose of achieving a striking effect inside the grenade. The outer part of the pot is higher and wider than the inner part of the pot, so that it can move freely to and fro in the former. As a result, since the inner pot can have 2 to 4 inn-i air around the circumference, if only (the primer is sufficiently wide, any fine work is omitted. In the initial position, the inner pot a is held in the outer b by drag springs c . the drag springs are arranged so that the inner pot does not slip home detour to the front, thus preventing the intention impact effect. In ler (transport yet secures a locking pin d the inner pot against premature slippage.

The upper end of the inner pot has a primer e, to which a set tube f and a detonator are connected inside the pot. The set tube consists of two or more parts that have been produced in different manufacturing processes in order to prevent puncturing in the event of any manufacturing errors.

All sensitive parts are sealed watertight.

The outer pot has your primer on it of inner pot facing end wall a pen, which when you open the inner On the outer primer. The inner pot is therefore as a firing pin, which is driven by its own weight. Because the inner Pot is arranged freely movable, is also a shaking movement when it is served generated, which is the last remainder of the fuel, driven by the powder gases and shocked by the impact at the moment of hitting the earth, etc., hurled forward into the detonator and so, if not unconditionally Accuracy, an impact detonator effect achieved.

The fire igniter is switched to an impact igniter on impact.

This version offers a very special advantage without a special impact fuse also in that a solid elastic handle can be used, the allowed a long throw.

Another embodiment of the grenade with a fire and impact fuse is shown in Figs. 2 and 3 in two different positions (start and end position).

As an impact detonator, almost any detonator that hits the every situation works, to be used. It must, however, be used for a specific purpose be appropriate. A known percussion fuse is shown as an example, in which a movable body swings out between conical surfaces.

The unlocking is achieved in that a fork h is withdrawn by relative movement between the handle sleeve and the other moving parts of the hand grenade. The two prongs of the fork form the lock for a Federringk, the IThe alone or together with 1 Stätzkörpern loading moveable parts throughout, apart keeps in 'the Aufschlagzänders before the focus are.

After the fork has been withdrawn, the spring ring k snaps back and releases the movable parts, m ', which ignite the primer in a known manner.

The escapement device used in grenades with an impact fuse has the purpose of delaying the unlocking of the percussion fuse until all parts of the hand grenade have assumed the same speed in flight, in order to prevent a premature action of the percussion zander during the throw.

The purpose is achieved in that the retaining fork h for the Impact fuse not directly with the handle, but with a spiral spring or the like is associated, which, held in the rest position by counter pressure, itself can not expand, but then with the relative movement between the stem and the remaining moving parts of the hand grenade as soon as there is free space to expand has arisen, pulls the retaining fork back. It is so a resistance to the spring created, which only allows a slow expansion of the spring.

In the embodiment shown in FIGS. 2 and 3 , the resistance consists of a burning charge p, which is ignited by the impact of a firing pin on a primer and only opens the space for the spring to fall apart after it has been completely destroyed.

The ignition of the support set occurs through relative movement between Handle sleeve and the moving parts of the hand grenade.

The condition for reliable ignition is that the blow required for ignition is always equally strong and short. This is achieved in that the grip sleeve i with a coupling q (Fig. 2 and 3), which is held in a guide, is connected, which bolt the impact. releases only after a very specific stroke, i.e. always with the same impact effect.

Claims (3)

PATENT CLAIMS. i. Throwing grenade with two mutually movable Parts, characterized in that the inner part, which contains the explosive charge, is arranged so movably in the outer part that it is through the centrifugal the grenade occurring centrifugal force after overcoming a block a time fuse ignited. : 2. Litter grenade according to claim i with a Schla-igniter, characterized in that the explosive device which can be displaced in the outer pot or cup of the grenade is provided with a tubular reduction which protrudes into the handle or cup body of the grenade and at its lower end receives the firing pin with its spring . 3. Throwing grenade according to claim i, characterized in that the firing pin has a coupling (q) held in a guide, which emerges from the guide after always the same stroke and releases the firing pin with always the same striking effect.
