Definitions
- the present invention relates to a hand grenade for producing smoke, in particular for producing colored smoke.
- a corresponding smoke is widely used in the military field and for security purposes, for example, as a simple form of remote communication.
- the smoke grenades carried as hand grenades produce smoke of a certain quality after activation, which is defined by the composition of sentences contained in the smoke body.
- the different textures of the smoke, for example different colors, are made possible by different numbers of different garnets.
- Object of the present invention is therefore to provide a hand grenade, which can produce different textures of smoke depending on the requirement requirements and no unused effect charges are discarded with the hand grenade according to the invention.
- a hand grenade for generating smoke with a housing which comprises outflow openings for the smoke to be generated. These outflow openings may be designed as holes in the housing, which may optionally be closed with a membrane permeable on one side.
- the hand grenade according to the invention also has a detonator head, which comprises means for igniting the hand grenade.
- a detonator head which comprises means for igniting the hand grenade.
- These means for firing the hand grenade may be of a mechanical nature, such as a piezoelectric element or electrical and chemical nature. All means for igniting the hand grenade is common that they can initiate a pyrotechnic element.
- a firing and deceleration path which may be initiated by the means for firing the hand grenade.
- the ignition and delay line is intended to ignite or disassemble a corresponding active charge.
- the ignition and delay line is associated with a time delay, so that after initiation of the ignition and delay line this time delay can ignite or disassemble an active charge.
- Such active charge is also provided in the housing, which can be ignited on the ignition and delay line or can be disassembled. By burning or decomposing the active charge creates a carrier gas in the housing. If the pressure is high enough by the carrier gas in the housing, this carrier gas is then discharged via the corresponding outflow openings from the hand grenade.
- the active charge may be introduced via a container in the hand grenade and contains a pyrotechnic mixture.
- this mixture consists of at least one oxidizing agent and at least one reducing agent, which serves to generate the carrier gas and the necessary heat energy.
- an effect area is provided in the housing, which can accommodate at least one effect module.
- Such an effect module contains an active substance, which changes into its gaseous state of aggregation due to the action of heat. This heat effect is generated by the burning or decomposition of the active charge, so that the then gaseous active substance of the effect module can escape together with the carrier gas from the outflow openings.
- any effect module to be used with the same type of effective charge can be burned or decomposed by the above-mentioned construction. It must therefore be provided in the housing of the hand grenade only an active charge to burn off the effect charges or disassemble.
- the effect modules can thus be manufactured separately from the active charge and stored until use. This allows a space-saving storage of the effect modules.
- the effect module according to the invention preferably has a shell which completely comprises the active ingredient of the effect module.
- the effect module comprises at least one organic active substance.
- This organic active ingredient is carried out in a particular preferred embodiment as a dye. This makes it possible that the smoke generated by the hand grenade is applied as a color smoke.
- the means for ignition comprise an actuator.
- Said actuator triggers the initiation of the igniter head when activated.
- the initiation can be caused by electrical, chemical or mechanical action.
- the actuator itself can act electrically, mechanically or magnetically.
- the actuator can be triggered manually or remotely controlled.
- the hand grenade for receiving remote control signals then has a corresponding receiving unit.
- this is preferably carried out as a hand lever. In manual operation of the hand lever then sets the ignition of the hand grenade in the first of the igniter head is activated, this then initiates the ignition and delay line and ignited after the delay time, the effective charge through the ignition and delay line or disassembled.
- the active charge itself preferably comprises a pyrotechnic substance mixture which can be burned off or decomposed while generating heat. Due to the resulting heat development, the effect module is heated accordingly, so that it can emerge after its transition into the gaseous state of matter together with the carrier gas from the outflow openings.
- the hand grenade according to the invention can produce various types of smoke, preferably colored smoke. Equally conceivable, however, are different densities of the smoke, different shades of gray and even smoke with infrared or UV components.
- the effect module preferably comprises at least one organic substance. This can for example be designed as a dye. It is also possible to mix several organic substances in one effect module to cause a mixing effect for the smoke, for example a yellow coloration with infrared component.
- effect modules can be introduced into the effect area of the housing, which then together generate a mixture of the smoke.
- two effect modules can be introduced, one for producing colored smoke and one for producing UV components in the smoke.
- the housing contains an opening, via which effect modules can be introduced into the effect area of the housing. This is done preferably by inserting the effect modules in the housing of the hand grenade according to the invention.
- the opening can preferably be closed with a closure.
- This closure can be a separate component that is attached after insertion of the effect module in or at the opening to hold the effect module in the hand grenade.
- the effect area has a thread and the effect module has a corresponding mating thread.
- the effect module can form the closure, namely with its opening facing the end.
- Figure 1 a schematic representation and section through a hand grenade according to the invention.
- FIG. 1 shows an embodiment of the hand grenade according to the invention for producing smoke.
- the hand grenade has a housing which is shown cut in Figure 1 in order to show the features within the housing can.
- the housing has outflow openings 3, which serve to let out the smoke generated within the housing to the outside.
- the discharge ports 3 may be closed with a membrane to allow the discharge of smoke from the housing, but not to allow any fluids to enter from the outside of the housing.
- the hand grenade according to the invention also has a detonator head 1, which comprises means for igniting the hand grenade.
- the means for ignition further comprise an actuator 6, which is designed in the present figure as a hand lever and thus acts mechanically.
- the actuator serves to activate the igniter head 1. This is done in the present case by moving the hand lever.
- the igniter head 1 initiates the activation of an ignition and delay line 2. This is preferably carried out as a pyrotechnic composition, which has a certain burning time and thus causes the delay.
- an active charge 4 which is also arranged in the housing of the hand grenade.
- the active charge 4 is ignited by the ignition and burned or decomposed, creating a Carrier gas is generated.
- the carrier gas then spreads inside the housing of the hand grenade.
- an effect area is provided, which can accommodate at least one effect module 5.
- This effect module 5 contains an active substance, which can change into its gaseous state of aggregation due to the evolution of heat. This heat is generated by the burning or disassembly of the active charge 4. After passing into the gaseous state of matter, the active substance can then emerge from the outflow openings 3 together with the carrier gas.
- the effect module 5 contains an active substance, preferably an organic active substance, which adds a certain property to the smoke produced, for example a certain color.
- the organic agent may also be designed as a dye.
- a shell may be provided which completely encompasses the active substance of the effect module 5.
- the housing of the hand grenade has an opening via which the effect module 5 can be introduced into the effect area of the housing.
- the effect area of the housing is provided with a thread and the effect module with a corresponding mating thread, so that the effect module 5 can be screwed into the effect area of the housing.
- a closure 7 is preferably provided, with which the opening can be closed.
- This closure 7 can be designed as a separate component, which is screwed by screwing in or on the opening. Further closure possibilities for the closure 7 are a quick-release closure or a magnetic closure.
- the closure 7 can also be formed from the effect module 5, specifically in the preferred manner after screwing in one end of the effect module 5 forms this closure. This is the end of the effect module 5, which points to the opening. In this case, it is proposed to manufacture the effect module 5 to the same extent as the effect area in which it can be accommodated. This ensures a smooth completion of the opening.
- the present invention is not limited to the aforementioned features. Rather, further embodiments are possible.
- the outflow openings can be attached to the bottom or the head of the hand grenade.
- the ignition and delay line can be electrically designed so that no burn-off is caused, but the delay is electrically controlled.
