  • Publication number: 20240118062
    Abstract: The present disclosure relates to a pyrotechnic object, in particular an irritation body, irritation projectile or ammunition, comprising an ignition device, comprising a delay chamber extending along a delay path, in which chamber a delay charge is accommodated, and comprising at least one and preferably a plurality of effect chambers in which or in each of which an effect charge to be ignited is accommodated, wherein the delay chamber is transversely connected to a respective effect chamber via a respective over-ignition opening which branches off from the delay chamber and forms an over-ignition path, wherein in the case of a plurality of effect chambers the plurality of over-ignition openings are arranged successively downstream along the delay path in the order of the effect charges to be ignited.

  • Patent number: 10996034
    Abstract: An irritation member having a housing, wherein the housing has a front side and a rear side, as well as lateral surfaces connecting the front side and the rear side. The front side and rear side are larger than the lateral surfaces, thereby producing a parallelepipedal housing. The irritation member has blow-out openings on the lateral surfaces and an actuation element that is provided in a recess of the housing. In the event of non-actuation, the actuation element is thereby received in the recess of the housing and thus does not increase the size of the housing. As a result, the irritation member does not look like a conventional irritation member.

  • Publication number: 20200149851
    Abstract: A rolling preventer for reducing rolling movements of a grenade, wherein the rolling preventer has at least one hindering element, which counteracts rolling movements of the grenade and can consequently reduce the rolling movement. The rolling preventer according to the invention also has a clearance, by which the rolling preventer can be attached to a grenade. For this purpose, the grenade is inserted through the clearance and the rolling preventer is thereby fastened to the grenade. Also proposed is a grenade, with a housing, an actuating element and a safety device, wherein the grenade is equipped with a rolling preventer according to the invention.

  • Patent number: 9016205
    Abstract: An irritation body (100, 100?) is proposed, which is formed by at least two modules (101, 102). The upper module (101) serves for acceptance of an ignition head (1) with tilt lever (3) and comprises upper blow-out apertures (8, 9). The lower module (102) is intended for acceptance of an effect-charge (11) with the effect-charge (11) being integrated in a central chamber (10) of a module (102). The chamber (10) itself is functionally connected with the upper blow-out apertures (8, 9) and also with the lower blow-out apertures (12, 18, 19, 20) in the lower module (102). The chamber (10) in the lower module (102) can, depending upon module (102), be selected in different sizes, which produces, under concomitant volume variability, output variability with defined increase in output.

  • Publication number: 20060283346
    Abstract: A rocker-arm igniter for irritation grenades, hand grenades, smoke or fog grenades, or similar, includes a rocker arm that may be pivoted by a tensioned spring about a pivot axis from a initial position into a second position, and that is firmly attached to a striker that, when the rocker arm is pivoted into its second position, strikes a igniter element of the rocker-arm igniter. A first mechanical securing device with a first securing device element is provided that holds the rocker arm in its initial position. Additionally, a second mechanical securing device with a second securing device element is provided that also holds the rocker arm in its initial position. The rocker arm is released to pivot into its second position only after removal of both securing device elements.
