Hand grenade for producing smoke

Abstract

A hand grenade for producing smoke, having a housing provided with outflow openings for the smoke to be produced. The hand grenade also has a fuse head having an igniter for igniting the hand grenade and an ignition and delay line. An active charge can be ignited via the fuse head and the ignition and delay line, creating a carrier gas in the housing. An effect region is also provided in the hand grenade, by means of which at least one effect module of the hand grenade can be supplied. The effect module contains an active ingredient that can be converted into its gaseous state of aggregation by the action of heat and can flow out of the outflow openings with the carrier gas.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawing which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein the sole FIGURE is a schematic illustration and cross section through a hand grenade according to an exemplary embodiment of the invention.

DETAILED DESCRIPTION

(2) The FIGURE shows an exemplary embodiment of the hand grenade according to the invention for producing smoke. In addition, the hand grenade possesses a housing, which is shown as a cross section in the FIGURE in order to be able to show the features within the housing.

(3) The housing comprises outflow openings 3 which are used to allow the smoke produced within the housing to exit toward the outside. The outflow openings 3 can be sealed using a diaphragm in order to make the output of smoke from the housing possible, however, thereby not allowing any fluid from the outside of the housing to enter the inside of it.

(4) Furthermore, the hand grenade according to the invention comprises a fuse head 1, which comprises an igniter to ignite the hand grenade. The igniter for igniting furthermore comprise an actuator 6, which is designed as a manual lever in the present FIGURE, thereby acting on a mechanical level. The actuator is used to activate the fuse head 1. In the present case, this occurs by moving the manual lever.

(5) The fuse head 1 initiates the activation of an ignition and delay line 2. This is preferably designed as a pyrotechnic composition, which has a certain burn duration, thereby causing the delay.

(6) After the delay the burning of the ignition and delay line 2 has passed, this ignites an active charge 4, which is also arranged within the housing of the hand grenade. Due to the ignition, the active charge 4 is ignited, burned off and broken down, whereby a carrier gas results. The carrier gas then disperses inside the housing of the hand grenade.

(7) An effect region is provided in the housing of the hand grenade, which can accommodate at least one effect module 5. This effect module 5 contains an active ingredient, which can be converted into its gaseous state of aggregation due to heat development. This action of heat is produced by the burning and breaking down of the active charge 4. After conversion into the gaseous state of aggregation, the active ingredient can then flow out of the outflow openings 3 together with the carrier gas.

(8) The effect module 5 contains an active ingredient, preferably an organic active ingredient, which gives the produced smoke a certain feature, for example, a certain color. Thereby, the organic active ingredient can also be designed to be a colorant.

(9) For better handling and for creating a storage possibility of the effect module 5, a shell can be provided, which completely encloses the active ingredient of the effect module 5.

(10) According to the invention, the housing of the hand grenade possesses an opening, via which the effect module 5 can be introduced into the effect region of the housing. In a particular embodiment, in addition, the effect region of the housing is provided with a thread and the effect module is provided with a corresponding mating thread so that the effect module 5 can be screwed into the effect region of the housing.

(11) The introduction of the effect module 5 is shown in FIG. 1 by the underside of the hand grenade.

(12) In order to keep the effect module 5 within the effect region, a closure 7 is preferably provided, by means of which the opening can be sealed. This closure 7 can be designed as an intrinsic component, which is screwed into or onto the opening by the screw connection. Other closure possibilities for the closure 7 include a quick-release closure or a magnetic closure. Similarly, however, the closure 7 can also be formed out of the effect module 5, namely that an end of the effect module 5 preferably forms this closure after screwing in. This is the end of the effect module 5 which faces the opening. In this case, it is proposed to manufacture the effect module 5 with the same dimensions as the effect region in which it can be received. By means of this, a level sealing of the opening is ensured.

(13) The present invention is not limited to the aforementioned features. On the contrary, further embodiments are possible. In this way, the outflow openings can be applied onto the base or the head of the hand grenade. Similarly, the ignition and delay line can be electrically designed so that no burning of this is caused, but the delay is electrically controlled.

(14) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
