Stun grenade with time delay trigger

a trigger and time delay technology, applied in the field of non-lethal missiles, can solve the problems of not having the capacity to stun, and pyrotechnic triggers may not be preferred, and achieve the effect of controlling the timing of operation of grenade simulators and stun grenades

Problems solved by technology

Practice grenades may be similar in providing for generation of light and noise, but without the capacity for stunning.
Unlike conventional grenades pyrotechnic triggers may not be preferred due to the potential for causing injury.

Embodiment Construction

[0018]Referring now to the drawings FIG. 1 illustrates a grenade simulator 10. Grenade simulator 10 includes a cylindrical housing 12, sized to be easily grasped in a hand. The cylindrical housing is closed at one end by a hemispherical flash globe 50 and at the other end by a cap 52. A handle 28 is shown flush with housing 12 where it may be retained by a safety (not shown) or held in place by hand.

[0019]Referring to FIG. 2, the consequences of release of handle 28 of grenade simulator 10 are illustrated. Upon release of a hold on grenade simulator 10 handle 28 swings outwardly from housing 12. The movement of handle 28 initiates operations (described below) which result in a bright flash being emitted from flash globe 50 at one end of the housing 12 and the inflation until rupture of a rupture bag 54 at the opposite of the housing. Rupture of the rupture bag 54 releases a volume of air at a pressure calculated to generate a shock wave evocative of sound generated by an explosion. ...

Abstract

A grenade simulator comprises a housing with an integral internal track. A carriage is mounted on the track for linear movement. A travel limit is provided at one end of the track to limit movement of the carriage on the track. A gas source is installed on the carriage. A drive spring installed between the carriage and the housing for urging the carriage against the travel limit. A multi-link trigger is installed on the housing for holding the carriage away from the travel limit until the multi-link trigger is released. A bayonet opens the gas source upon the carriage reaching the travel limit. A release delay is integral with the multi-link trigger.

Description

BACKGROUND[0001]1. Technical Field[0002]The field relates to non-lethal missiles for practice, controlling crowds and subduing individuals, and more particularly to triggers controlling timing of operation of grenade simulators and stun grenades.[0003]2. Description of the Art[0004]Stun grenades are typically hand thrown missiles which include a small pyrotechnic charge to create a flash of light and noise. Practice grenades may be similar in providing for generation of light and noise, but without the capacity for stunning. Unlike conventional grenades pyrotechnic triggers may not be preferred due to the potential for causing injury.[0005]Woodall, U.S. Pat. No. 5,996,503 teaches a spring loaded ram for piercing a gas reservoir, a spring biased trigger lever which pivots to release the spring loaded ram and a “release activated delay” which delays operation of the device after release of the trigger lever. Woodall's delay mechanism is described as providing for temporarily restraini...
