IGNITER WITH A DELAY TIME THAT CAN BE SET

Abstract

The invention relates to an igniter with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter has, in a delay section, preferably in the fuse head, a relief bore that can be closed or opened.

Claims

1-11. (canceled)

12. An igniter with an adjustable delay time (Vz), wherein a relief bore is provided in a delay line of a delay charge.

13. The igniter as claimed in claim 12, wherein the relief bore can be opened or closed by a split pin, a pin or the like.

14. The igniter as claimed in claim 13, wherein the pin can be pulled, pressed, or twisted.

15. The igniter as claimed in claim 12, wherein two different delay times (Vz) can be set.

16. The igniter as claimed in claim 12, wherein that delay times (Vz) of 0.5 s or 1.0 s, 1.0 s or 1.5 s, 1.5 s or 2 s etc. can be set.

17. An irritation body with an igniter as claimed in claim 12.

18. The irritation body as claimed in claim 17, wherein the relief bore is inserted in the igniter head.

19. The irritation body as claimed in claim 18, wherein the opening of the relief bore is realized by a slight movement of the igniter head upwards relative to the housing.

20. The irritation body as claimed in claim 17, wherein a safety catch prevents manipulation of the Vz adjustment and of a split pin.

21. A hand grenade with an igniter as claimed in claim 12.

22. The hand grenade as claimed in claim 21, wherein the relief bore is inserted into the igniter head.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The invention will be explained in more detail on the basis of an exemplary embodiment with a drawing.

[0016] FIG. 1 shows a representation of an igniter 1, here an igniter head, of a known irritation body which is not shown in detail. This figure shows the igniter head 1′ in a representation in which a rocker lever 3 is on the left on the igniter head 1′ as well as in a sectional representation in which the rocker lever 3 is to the right of this. The rocker lever 3 is secured by a split pin 4 in a known manner and keeps a spring-loaded firing pin 17 or striker/igniter (a detonator), i.e. an object with explosives, from striking a percussion cap 18.

DETAILED DESCRIPTION

[0017] As can be seen from the figure in the representation on the right, the igniter head 1′ has a relief bore 15 in a delay line 24, which can be released by another split pin, a pin 16 or the like.

[0018] The relief bore 15 is located in the delay line 24 (channel) and this is preferably within the igniter head 1′.

[0019] The operation is as follows:

[0020] The irritation body is protected by the safety catches 20. The safety catch 20 is pressed into the gap 22, for example during assembly. In addition, this safety catch 20 prevents the detonator 17 from unintentionally striking the ignition cap 18 by the flap 23 protruding into the igniter head 1′. This further safety catch 20 is only removed immediately before use. It therefore also prevents any manipulation of the Vz adjustment and the split pin 4 (for example a rotary split pin). Only after removing the safety catch 20 does a pressure safety catch, which is not shown in detail, disengage and release the split pin 4.

[0021] For setting the delay time Vz, the split pin 16 can remain in the relief bore 15 or can be pulled out of it. When the relief bore 15 is opened, the pyrotechnic delay charge 12 burns without pressure and thus slower than under pressure. This is achieved by a longer Vz compared to a closed relief bore 15. If, on the other hand, the relief bore 15 remains closed, the burning of the pyrotechnic delay charge 12 takes place as originally set by means of the quantity of the delay charge, i.e. normally.

[0022] This exemplary embodiment refers to an irritation body above. However, the application of the inventive idea of the simple setting of the delay time is not limited to this use. An application with a hand grenade is also conceivable.
